Preliminary Prospectus Supplement
(To Prospectus dated May 27, 2025)

GDS Holdings Limited

American Depositary Shares

We are offering American depositary shares (“ADSs”) (each representing as of the date hereof eight Class A ordinary shares of GDS Holdings Limited, par value US$0.00005 per share), which we refer to as the “Delta Placement of Borrowed ADSs”. We will loan such ADSs to J.P. Morgan Securities plc (the “ADS Borrower”) pursuant to an ADS lending agreement, which we refer to as the “ADS Lending Agreement,” for sale by an affiliate of the ADS Borrower, J.P. Morgan Securities LLC (the “Borrowed ADS Underwriter”), pursuant to this prospectus supplement. In this prospectus supplement, we also refer to the ADSs borrowed under the ADS Lending Agreement as the “Borrowed ADSs” and to the ADS loan transaction pursuant to the ADS Lending Agreement as the “ADS Loan.” We believe that under United States generally accepted accounting principles, or U.S. GAAP, the Borrowed ADSs will not be considered outstanding for the purpose of computing and reporting our earnings per ADS. We will not receive any proceeds from the sale of the Borrowed ADSs in this offering, but we will receive from the ADS Borrower or its affiliate a nominal lending fee of US$0.0004 per each Borrowed ADS. The ADS Borrower or its affiliates will receive all the proceeds from the sale of the Borrowed ADSs.

The ADS Borrower or its affiliates will use the short positions resulting from the Delta Placement of the Borrowed ADSs to facilitate privately negotiated derivative transactions, by which certain investors in our % convertible senior notes due 2032 (the “convertible senior notes” and the “Concurrent Notes Offering”, respectively) described below, who employ a convertible arbitrage strategy, will hedge their market risk with respect to the convertible senior notes. These derivative transactions are expected to be on market-standard terms for such type of transactions. During the term of such transactions, such investors may use their synthetic short positions established thereunder at their sole discretion.

The number of Borrowed ADSs to be sold hereunder will depend on what portion of investors in the Concurrent Notes Offering desire to hedge their investments through the derivative transactions with the ADS Borrower or its affiliates, will be determined at the time of pricing of the Delta Placement of Borrowed ADSs and is expected to be no greater than commercially reasonable initial short positions of such convertible arbitrage investors. The underwriters will initially offer the Borrowed ADSs to the public at US$ per ADS, which is the same price as the price to the public per ADS in the Concurrent Primary ADSs Offering (each as defined below), and may subsequently offer such Borrowed ADSs for sale in one or more transactions on the Nasdaq Global Market, in the over the counter market, through negotiated transactions or otherwise, at market prices prevailing at the time of sale, at prices related to prevailing market prices at the time of sale or at negotiated prices. See “Description of the Delta Placement of Borrowed ADSs and Concurrent Offering of Convertible Senior Notes” and “Underwriting (Conflicts of Interest).” We do not expect to lend any additional ADSs to the ADS Borrower or any other party to facilitate any short positions that may be desired by any initial or subsequent investors in the convertible senior notes after this offering, and will not lend any additional ADSs following any exercise by the initial purchasers in the concurrent convertible notes offering described below of their option to purchase additional convertible senior notes. There can be no assurance that the ADS Borrower will continue to facilitate any privately negotiated derivative transactions by which any convertible arbitrage investors in our convertible senior notes may be hedging their exposure to the market risk of our ADSs and/or Class A ordinary shares during the term of such convertible senior notes. There is no intent that the Delta Placement of Borrowed ADSs will create any inventory of our ADSs and/or Class A ordinary shares with the ADS Borrower or its affiliates that could be made available for borrowing to any investor in our convertible senior notes during the term thereof.

Our ADSs are listed on the Nasdaq Global Market under the symbol “GDS” and our Class A ordinary share are listed on the Main Board of the Hong Kong Stock Exchange under the stock code “9698.” The last reported sale price of our ADSs on the Nasdaq Global Market on May 23, 2025 was US$28.50 per ADS.

TABLE OF CONTENTS

Neither this prospectus supplement nor the accompanying prospectus is an offer in respect of our convertible senior notes. Our convertible senior notes are being concurrently offered in a separate offering in reliance on Rule 144A under the Securities Act of 1933, as amended, or the “Securities Act”, to persons reasonably believed to be “qualified institutional buyers” (as defined in Rule 144A under the Securities Act).

Concurrently with this offering and the Concurrent Notes Offering, we are also offering 5,200,000 ADSs pursuant to a separate prospectus supplement and the accompanying prospectus (the “Concurrent Primary ADS Offering”). We refer to these ADSs as the “Primary ADSs.” The last reported sale price of our ADSs on the Nasdaq Global Market on May 23, 2025 was US$28.50 per ADS. We will receive all of the net proceeds from the offering of the Primary ADSs. This prospectus supplement is not an offer in respect of the Primary ADSs, which will be made under a separate prospectus supplement filed with the SEC pursuant to Rule 424(b) of the Securities Act and the base prospectus.

The completion of the Delta Placement of Borrowed ADSs is contingent upon the completion of both the Concurrent Primary ADSs Offering and the Concurrent Notes Offering, and the completion of each of the Concurrent Primary ADSs Offering and the Concurrent Notes Offering is contingent upon the completion of each other and the Delta Placement of Borrowed ADSs hereunder. If the Concurrent Notes Offering is not consummated, the Concurrent Primary ADSs Offering will terminate, the ADS Loan under the ADS Lending Agreement will terminate, and the Delta Placement of Borrowed ADSs will terminate and all of the Borrowed ADSs (or ADSs fungible with the Borrowed ADSs or other substitute securities or property as provided for in the ADS Lending Agreement) must be returned to us.

We expect that delivery of the Borrowed ADSs will be made through the facilities of The Depositary Trust Company on , 2025 (such settlement being referred to as “T+2”). Under Rule 15c6-1 under the Securities Exchange Act of 1934 (the “Exchange Act”), as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the ADSs more than one business day prior to , 2025 will be required, by virtue of the fact that the Borrowed ADSs settle on T+2 to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Borrowed ADSs who wish to trade the Borrowed ADSs during such period should consult their advisors.

Investing in the ADSs involves risk. See “Risk Factors” beginning on page S-21 of this prospectus supplement for a discussion of certain risks that you should consider in connection with an investment in the ADSs.

GDS Holdings Limited is not an operating company in mainland China, but instead is a holding company incorporated as a Cayman Islands exempted company. PRC laws and regulations impose certain restrictions or prohibitions on foreign ownership of companies that engage in telecommunications-related businesses, including the provision of value-added telecommunications services, or VATS. Our internet data center businesses are classified as VATS by the PRC government. Accordingly, we operate substantially all of these business operations in mainland China through the consolidated variable interest entities, or VIEs, and their subsidiaries, as well as through our subsidiaries, and rely on contractual arrangements to control the business operations of the consolidated VIEs. GDS Holdings Limited has no equity ownership in the consolidated VIEs. As used in this prospectus supplement, “GDS,” “our company,” “the Company,” “we,” “our” or “us” refers to GDS Holdings Limited, an exempted company incorporated in the Cayman Islands with limited liability on December 1, 2006 and, where the context requires, its consolidated subsidiaries and the consolidated affiliated entities, including the VIEs and their subsidiaries, from time to time. Investors in the ADSs are not purchasing an equity interest in the consolidated VIEs and their subsidiaries in mainland China, but instead are purchasing an equity interest in a holding company incorporated as a Cayman Islands exempted company and its subsidiaries (excluding the VIEs and their subsidiaries).

Our corporate structure is subject to risks associated with our contractual arrangements with the consolidated VIEs. These contractual arrangements may not be as effective as direct ownership in providing us with control over the consolidated VIEs and we may have to incur substantial costs and expend significant resources to enforce such arrangements in reliance on legal remedies under PRC law. The enforceability of the agreements under the contractual arrangements has not been tested in a court of law. There are also uncertainties regarding the interpretation and application of current and future PRC laws, regulations and rules regarding the status of the rights of our Cayman Islands holding company with respect to the contractual arrangements. If our corporate structure or contractual arrangements were found to be in violation of any existing or future PRC laws or regulations, we could be subject to severe penalties, and the relevant regulatory authorities would have discretion in dealing with such violations. As a result, we would be unable to direct the activities of the consolidated VIEs and their subsidiaries, receive their economic benefits and/or claim our contractual control rights over the assets of the VIEs and their subsidiaries that conduct substantially all of our operations in

TABLE OF CONTENTS

mainland China, we would no longer be able to consolidate such VIEs and their subsidiaries in our consolidated financial statements in accordance with U.S. GAAP, which would likely materially and adversely affect our financial condition and results of operations, and cause the value of our securities to significantly decline or become worthless. For a detailed description of the risks associated with our corporate structure, please refer to risks disclosed under “Item 3. Key Information — D. Risk Factors — Risks Related to Our Corporate Structure” in our annual report on Form 20-F for the fiscal year ended December 31, 2024 (the “2024 Annual Report”), which is incorporated by reference in this prospectus supplement.

In addition, we face various risks and uncertainties related to doing business in China. Our business operations are primarily conducted in China, and we are subject to complex and evolving PRC laws and regulations. For example, we face risks associated with regulatory approvals on offshore offerings, anti-monopoly regulatory actions, and oversight on cybersecurity and data security and protection, which may impact our ability to conduct certain businesses, accept foreign investments or financing, or list on a United States, Hong Kong or other foreign exchange. These risks could result in a material adverse change in our operations and the value of our ADSs, impact our ability to offer or continue to offer securities to investors, or cause the value of our securities to significantly decline or become worthless. For more details of the risks we face related to doing business in China, see “Item 3. Key Information — D. Risk Factors — Risks Related to Doing Business in the People’s Republic of China” in our 2024 Annual Report.

Pursuant to the Holding Foreign Companies Accountable Act, or the HFCA Act, as amended by the Consolidated Appropriations Act, 2023, if we have retained a registered public accounting firm to issue an audit report where the registered public accounting firm has a branch or office that is located in a foreign jurisdiction and the Public Company Accounting Oversight Board, or the PCAOB, has determined that it is unable to inspect or investigate completely because of a position taken by an authority in the foreign jurisdiction, the Securities and Exchange Commission, or the SEC, will identify us as a “covered issuer,” or SEC-identified issuer; and if we were to be identified as an SEC-identified issuer for two consecutive years, the SEC would prohibit our securities (including our shares or ADSs) from being traded on a national securities exchange or in the over-the-counter trading market in the United States. In December 2021, the PCAOB made its determinations, or the 2021 determinations, pursuant to the HFCA Act that it was unable to inspect or investigate completely registered public accounting firms headquartered in mainland China or Hong Kong, including our auditor. In December 2022, the PCAOB vacated the previous 2021 determinations, and as a result, our auditor is no longer a registered public accounting firm that the PCAOB is unable to inspect or investigate completely as of the date of our 2024 Annual Report or at the time of issuance of the audit report included therein. As such, we do not expect to be identified as an SEC-identified issuer following the filing of our 2024 Annual Report. However, the PCAOB may change its determinations under the HFCA Act at any point in the future. In particular, if the PCAOB finds its ability to completely inspect and investigate registered public accounting firms headquartered in mainland China or Hong Kong is obstructed by the PRC authorities in any way in the future, the PCAOB may act immediately to consider the need to issue new determinations consistent with the HFCA Act. We cannot assure you that the PCAOB will always have complete access to inspect and investigate our auditor, or that we will not be identified as an SEC-identified issuer again in the future. If we are identified as an SEC-identified issuer again in the future, we cannot assure you that we will be able to change our auditor or take other remedial measures in a timely manner, and if we were to be identified as an SEC-identified issuer for two consecutive years, we would be delisted from Nasdaq and our securities (including our shares and ADSs) will not be permitted for trading “over-the-counter” either. For more details, see “Item 3. Key Information — D. Risk Factors — Risks Related to Doing Business in the People’s Republic of China — The audit report included in this annual report is prepared by an auditor which the U.S. Public Company Accounting Oversight Board was unable to inspect and investigate completely before 2022 and, as such, our investors had been deprived of the benefits of such inspections in the past, and may be deprived of the benefits of such inspections in the future” and “— If the PCAOB determines that it is unable to inspect or investigate completely our auditor at any point in the future, our ADSs may be prohibited from trading in the United States under the HFCA Act, as amended, and any such trading prohibition on our ADSs or threat thereof may materially and adversely affect the price of our ADSs and value of your investment” in our 2024 Annual Report.

INCORPORATION OF DOCUMENTS BY REFERENCE

The SEC allows us to “incorporate by reference” the information we file with them. This means that we can disclose important information to you by referring you to those documents. Each document incorporated by reference is current only as of the date of such document, and the incorporation by reference of such documents shall not create any implication that there has been no change in our affairs since the date thereof or that the information contained therein is current as of any time subsequent to its date.

SUMMARY

This summary highlights information contained elsewhere or incorporated by reference in this prospectus supplement. This summary is not complete and does not contain all of the information that you should consider before investing in the ADSs. You should read the entire prospectus supplement carefully, including the section titled “Risk Factors” in Exhibit 99.3 to the May 27 Form 6-K, the section titled “Risk Factors” of this prospectus supplement and under “Item 3. Key Information — D. Risk Factors” in our 2024 Annual Report and the financial statements and the notes thereto of our company, which are incorporated by reference in this prospectus supplement, and the other financial information appearing elsewhere or incorporated by reference in this prospectus supplement.

Business Overview

We are a leading developer and operator of high-performance data centers in China. In addition, we have a significant minority investment in DayOne, our equity investee, which develops and operates data centers in Southeast Asia and Northeast Asia. Accordingly, we derive shareholder value from our consolidated business in China and from our deconsolidated, but highly material, equity investment in DayOne.

Our facilities in mainland China are strategically located in primary economic hubs where demand for high-performance data center services is concentrated. Our data centers are designed and configured as high-performance data centers with large net floor area and power capacity, high power density and efficiency, and multiple redundancy across all critical systems. We are carrier and cloud neutral, which enables our customers to access all the major telecommunications networks, as well as the largest PRC and global public clouds which we host in many of our facilities.

We offer colocation and managed services, including direct private connection to leading public clouds, an innovative service platform for managing hybrid clouds. Our innovative and unique platform of interconnected data centers enables cloud service providers to expand in a flexible way in their key markets, and also enables enterprises to deploy their hybrid clouds in close proximity to the networked nodes of leading public clouds.

We have a 24-year track record of service delivery, successfully fulfilling the requirements of some of the largest and most demanding customers for outsourced data center services. As of March 31, 2025, we had an aggregate net floor area of 610,685 sqm in service, 90.9% of which was committed by customers, and an aggregate net floor area of 132,208 sqm under construction, 71.6% of which was pre-committed by customers.

We believe the market for high-performance data center services in mainland China continues to grow at a strong underlying rate. Demand is driven by rapid growth in the volume of data created, transmitted, processed and stored as a result of the accelerating trend of digital transformation and the rising adoption of new technologies such as cloud computing, 5G, artificial intelligence, big data, machine learning, blockchain, internet of things, augmented and virtual reality, e-payments and digital currency. This has been strongly endorsed and further encouraged by the PRC government policies which consistently and actively support technology-driven development and the growth of the digital economy. The PRC government has promoted the concept of “new infrastructure” which includes, among other things, largescale data centers, artificial intelligence and industrial internet. The PRC government has rolled out plan for overall layout of the country’s digital development. According to the plan, important progress will be made in the construction of a digital China by 2025, with effective interconnectivity in digital infrastructure, a significantly improved digital economy, and major breakthroughs achieved in digital technology innovation. A newly formed National Bureau of Data will be responsible for overall coordination and promoting the development of digital China.

Our platform of interconnected data centers and secured expansion capacity is strategically located to address this growing demand. We develop and operate our data centers predominantly in and around Shanghai, Beijing, Shenzhen, Guangzhou, and Chengdu/Chongqing, the primary financial, commercial, industrial and communications hubs in each region. We refer to the areas in and around these hubs as Tier 1 markets. Our customers typically use our data centers in Tier 1 markets to house their mission-critical, latency-sensitive data and applications. Our data locations provide convenient access for our customers and, furthermore, the extensive multi-carrier telecommunications networks in these markets enable our customers to enhance the performance and lower the cost of connectivity to our facilities.

TABLE OF CONTENTS

In the past, our data centers were mainly clustered in key urban districts within each Tier 1 market in accordance with customer preference. In order to keep pace with demand and overcome the challenge of creating new supply, we are also developing more data centers at strategy locations on the outer edge of these markets, including on campuses we can expand capacity in multiple phases. These outer edge developments, which we still consider Tier 1 markets, enable our hyperscale customers to fulfill their requirement for larger developments of IT capacity on a single site and to upscales over time, while remaining within acceptable parameters for network latency. In addition to our presence in Tier 1 markets, we also build, operate and transfer data centers at other locations selected by our customers in order to house their offline and less critical data and applications in lower cost areas where, at times, renewable energy sources are also accessible.

In recent years, we have seen strong growth in demand for high-performance data center services internationally. We believe that a significant part of this demand originates from the top tier of China and global technology companies, with many of which we have existing customer relationships. In order to better serve our customers’ requirements, we established DayOne in 2022, with its corporate headquarters in Singapore and its own dedicated management. In order to optimize performance, DayOne has transitioned within a short period of time to become independent of GDS with a strong and diversified shareholder base consisting of leading global investors. Following the closing of DayOne’s Series B equity financing on December 31, 2024, we owned approximately 35.6% of the equity interest of DayOne in the form of ordinary shares on an as-converted basis, and therefore no longer consolidate DayOne for accounting purposes.

From its inception, DayOne focused on creating a new global data center hub known as SIJORI, which integrates Singapore, Johor in Malaysia, and the Riau Islands in Indonesia. Building on its success in SIJORI, DayOne is entering the Tokyo and Greater Bangkok markets with new developments. DayOne also has a presence in Hong Kong. As of March 31, 2025, DayOne had total power committed of 539 MW, power capacity in service of 154 MW, power capacity under construction of 425 MW, and power utilized of 145 MW.

From our inception, we have built up our own in-house data center design capability, which we believe is unparalleled in the industry. We were one of the first movers in developing high-performance data centers in mainland China, anticipating the trend for IT to become increasingly mission-critical, and then in combining high availability with larger net floor area and power capacity to meet the unprecedented requirements of hyperscale cloud service providers and large internet companies. Our data centers are largescale, highly reliable and highly efficient facilities that provide a flexible, modular and secure operating environment in which our customers can house, power and cool the computer systems and networking equipment that support their mission-critical IT. We install high power density (which refers to the ratio of power capacity to net floor area) and optimize power usage efficiency, which enables our customers to deploy their IT systems more efficiently and reduce their operating and capital costs. As a result of our advanced data center design, high technical specifications and robust operating procedures, we are able to make service level commitments related to service availability and other key metrics that meet our customers’ required standards. Within our data centers, we have also developed an innovative service platform to assist our enterprise customers to integrate and control every aspect of their hybrid cloud computing environment across their private servers and one or more public cloud service providers. As of March 31, 2025, we served 937 customers, including PRC and global hyperscale cloud service providers and large internet companies, a diverse community of financial institutions, telecommunications carriers and IT service providers and large domestic private sector and multinational corporations, many of which are leaders in their respective industries. We host the largest public cloud platforms operating in mainland China, some of which are present in multiple GDS data centers. Agreements with our hyperscale cloud service provider and large internet customers generally have terms of three to ten years, while agreements with our financial institution and enterprise customers typically have terms of one to five years.

As of March 31, 2025, we operated 87 self-developed data centers with an aggregate net floor area of 606,097 sqm in service. We also operated capacity at third-party data centers with an aggregate net floor area of 4,588 sqm in service, which we lease on a wholesale basis and use to provide colocation and managed services to our customers. As of the same date, we also had an aggregate net floor area of 132,208 sqm under construction. In total, we have 95 self-developed data centers in service and under construction, and we have a total capacity of 742,893 sqm. As of the same date, we had an estimated aggregate developable net floor area of approximately 354,702 sqm held for potential future development. Our net revenue and results of operations are largely determined by the degree to which our data center capacity is committed or pre-committed as well

as its utilization. We had commitment rates for our area in service of 95.5%, 92.5%, 91.9% and 90.9% as of December 31, 2022, 2023, 2024 and March 31, 2025, respectively. We had utilization rates for our area in service of 71.8%, 73.9%, 73.8% and 75.7% as of December 31, 2022, 2023, 2024 and March 31, 2025, respectively. The difference between commitment rate and utilization rate is primarily attributable to customers who have entered into agreements but have not yet started to use revenue-generating services.

Our net revenue grew from RMB9,268.1 million in 2022 to RMB9,782.4 million in 2023, representing an increase of 5.5%, and increased to RMB10,322.1 million (US$1,422.4 million) in 2024, representing an increase of 5.5%. Our net revenue was RMB2,723.2 million (US$375.3 million) for the three months ended March 31, 2025. Our net loss increased from RMB1,266.1 million in 2022 to RMB4,285.4 million in 2023. Our net income was RMB3,303.8 million (US$455.3 million) in 2024 and RMB764.1 million (US$105.3 million) for the three months ended March 31, 2025, including gain on deconsolidation of subsidiaries. Our adjusted EBITDA increased from RMB4,333.7 million in 2022 to RMB4,733.0 million in 2023, and increased to RMB4,876.4 million (US$672.0 million) in 2024. Our adjusted EBITDA was RMB1,323.8 million (US$182.4 million) for the three months ended March 31, 2025. As of December 31, 2022, 2023, 2024 and March 31, 2025, our accumulated deficit was RMB5,179.7 million, RMB9,469.8 million, RMB6,044.4 million (US$832.9 million) and RMB5,281.4 million (US$727.8 million), respectively.

Our Business Model

Our core business operations entail the planning and sourcing of new data centers, developing such facilities, securing customer commitments, providing our colocation and managed services to customers, and maintaining high levels of service and customer satisfaction to develop and maintain long-term relationships with our customers. We focus on developing and operating what we refer to as high-performance data centers. These are data centers that feature large net floor area and power capacity, high power density and efficiency, and multiple redundancy across all critical systems.

Sourcing

Our strong customer and industry relationships offer us insight into the size, timing, and location of future demand which is reflected in our data center capacity development plan. Based on this insight, we aim to secure land and buildings with potential customer demand, together with the required power capacity and regulatory approvals, including energy quota under the energy conservation review opinion, for future development commensurate with anticipated demand for our services. Our in-house team begins sourcing potential sites a few years in advance of planned development. We source new data center capacity by: (i) acquiring or leasing property which we develop for use as data center facilities, whether through constructing on greenfield land, redeveloping brownfield sites, converting existing industrial buildings, or fitting out and equipping purpose-built building shells; (ii) leasing existing data center capacity from third-party wholesale providers; and (iii) acquiring high-performance data centers from other companies.

Regardless of the source of our data center capacity, we ensure that the facilities meet the high-performance standards required by our target customers.

Construction

After procuring greenfield or brownfield sites or existing industrial buildings or purpose-built building shells, we design and, through cooperation with developers, contractors, and suppliers, build out the facility to achieve our advanced design and high technical specifications.

We take a modular approach to developing, commissioning, equipping and fitting out of facilities, so that we can cater to a range of customer requirements with regard to redundancy, power density, cooling, rack configuration and other technical specifications. In addition, by taking a modular approach, we are able to phase our capital expenditures related to equipping and fitting out individual computer rooms in accordance with proven sales demand or contractual delivery commitments to customers.

Marketing

We usually commence marketing new data center facilities before we commence construction by seeking strong indications of interest from customers. We aim to convert such indications of interest into pre-commitment

S-3

TABLE OF CONTENTS

agreements for a substantial part of the capacity under development as early as possible in the construction cycle. Such pre-commitments typically come from anchor customers who require largescale capacity, such as hyperscale cloud service providers and large internet companies. Through securing such pre-commitments, we are able to reduce investment risk and optimize resource planning. Once construction is complete, and the data center enters service, we re-categorize area pre-committed as area committed. We aim to maintain high commitment rates for each of our data centers.

For certain sites, we deliberately do not seek pre-commitments, in order to reserve sufficient capacity for our financial institution and large enterprise customers who typically procure with a shorter lead time once data centers are in service. This also helps to ensure that we have sufficient capacity available to fulfill the anticipated expansion requirements of strategic customers who we are already serving in the same location. As a result of this sales approach, some of our data centers under construction and in service have lower pre-commitment and commitment rates, respectively.

Delivery

Once construction is complete, and the data center enters service, we re-categorize area under construction as area in service.

Anchor customers with largescale commitments typically move in over a period of 6 to 24 months, whereas financial institutions and large enterprise customers typically move in over a period of 3 to 12 months. The longer move-in period for anchor customers is due to the larger scale of their deployments and operational models, under which they increase utilization of committed data center capacity in multiple phases and in line with the increasing load on their IT systems. During such move-in periods, customers have the right to use part or all of the services for which they have committed. They are billed for the amount of services they actually use, subject to a minimum billable amount as stated in the sales agreements. Such minimum billable amount typically steps up over time. Customers are usually not allowed to terminate their sales agreements before the end of the move-in period. See “Business Overview — Our Customers — Sales Agreements.” The portion of area committed by customers which is revenue generating is referred to as area utilized. As a result of the flexibility granted to customers to use part or all of the services during the move-in period, some of our data centers have lower utilization rates.

Commitment and Utilization Rates

Our business model provides us with high levels of revenue visibility due to the long-term nature of our customer agreements and substantial backlog. Backlog is defined as area committed or pre-committed by customers but yet to be utilized (total area committed minus area utilized at the end of each period). As of December 31, 2022, 2023, 2024 and March 31, 2025, we had backlog of 228,787 sqm, 213,640 sqm, 176,904 sqm and 187,138 sqm, respectively. We maintained a consistent level of backlog across these periods primarily due to higher levels of customer commitments and pre-commitments. We endeavor to provide high levels of customer service, support, and satisfaction to maintain long-term customer relationships and high rates of agreement renewals for our services. Our churn rate, which we define as area terminated or expired without renewal during the quarter divided by total area utilized at the end of the preceding quarter, averaged approximately 1.4%, 1.2% and 0.9% in 2023, 2024 and the three months ended March 31, 2025, respectively.

For our in-service data centers, we aim to maintain high levels of long-term commitment and utilization rates. We had commitment rates for our area in service of 95.5%, 92.5%,91.9% and 90.9% as of December 31, 2022, 2023, 2024 and March 31, 2025, respectively. We had utilization rates for our area in service of 71.8%, 73.9%,73.8% and 75.7% as of December 31, 2022, 2023, 2024 and March 31, 2025, respectively. The difference between commitment rate and utilization rate is primarily attributable to customers who have not yet fully utilized all the revenue-generating services for which they have committed. Until the end of the move-in period, the area committed is not fully categorized as area utilized.

Due to the typical time lag for move-in, the continual expansion of our data center capacity, and the high proportion of anchor customers with largescale commitments, we expect that our utilization rate will continue to lag behind our commitment rate. For data centers that have been in operation for a longer period of time, the commitment rate and utilization rate will tend to converge, as customers have fully moved in.

Our Corporate Structure and Contractual Arrangements with the Consolidated Affiliated Entities

GDS Holdings Limited is not an operating company in mainland China, but instead is a holding company incorporated as a Cayman Islands exempted company. PRC laws and regulations impose certain restrictions or prohibitions on foreign ownership of companies that engage in telecommunications-related businesses, including the provision of VATS. Our internet data center businesses are classified as VATS by the PRC government. Accordingly, we operate substantially all of these business operations in mainland China through the consolidated VIEs and their subsidiaries, as well as through our subsidiaries, and rely on contractual arrangements, described below, to control the business operations of the consolidated VIEs. GDS Holdings Limited has no equity ownership in the consolidated VIEs. Revenues contributed by the VIEs and their subsidiaries accounted for 96.7%, 97.0%, 96.1% and 98.0% of our total revenues for the years of 2022, 2023, 2024 and the three months ended March 31, 2025, respectively. As used in this prospectus supplement, “we,” “us,” “our company,” “the Company” or “our” refers to GDS Holdings Limited, an exempted company incorporated in the Cayman Islands with limited liability on December 1, 2006 and, where the context requires, its consolidated subsidiaries and the consolidated affiliated entities, including the variable interest entities and their subsidiaries, from time to time. Investors in our ADSs are not purchasing an equity interest in the consolidated VIEs and their subsidiaries in mainland China, but instead are purchasing an equity interest in a holding company incorporated as a Cayman Islands exempted company and its subsidiaries (excluding the VIEs and their subsidiaries).

In addition, aside from our direct operations through our consolidated subsidiaries and consolidated VIEs, we also derive a significant proportion of our value and results of operations from DayOne, our equity investee, in which we hold a 35.6% equity stake and which develops and operates data centers in Southeast Asia and Northeast Asia. See “Item 4 — Information on the Company — B. Business Overview — Our Equity Investment in DayOne” and “Item 5 — Operating and Financial Review and Prospects — Overview — Discontinued Operations” in our 2024 Annual Report.

Our consolidated mainland China subsidiaries, the consolidated VIEs and their shareholders have entered into a series of contractual arrangements, including equity interest pledge agreements, shareholder voting rights proxy agreements, exclusive technology license and service agreements, intellectual property rights license agreements, exclusive call option agreements and loan agreements. The terms in each set of contractual arrangements with the consolidated VIEs and their shareholders are substantially similar. For more details of these contractual arrangements, see “Item 4. Information on the Company — C. Organizational Structure — Contractual Arrangements with Affiliated Consolidated Entities” in our 2024 Annual Report. We rely on these contractual arrangements to control the business operations of the consolidated VIEs. As a

result of these contractual arrangements, we are the primary beneficiary of Management HoldCo, GDS Shanghai, GDS Beijing and their respective subsidiaries, and, therefore, have consolidated their financial results in our consolidated financial statements in accordance with U.S. GAAP.

However, these contractual arrangements may not be as effective as direct ownership in providing us with control over the consolidated VIEs and we may have to incur substantial costs and expend significant resources to enforce such arrangements in reliance on legal remedies under PRC law. See “Item 3. Key Information — D. Risk Factors — Risks Related to Our Corporate Structure — We rely on contractual arrangements with the consolidated VIEs and their shareholders for our China operations, which may not be as effective as direct ownership in providing operational control and otherwise have a material adverse effect as to our business” and “Item 3. Key Information — D. Risk Factors — Risks Related to Our Corporate Structure — The individual management shareholders of our Management HoldCo may have potential conflicts of interest with us, which may materially and adversely affect our business and financial condition” in our 2024 Annual Report.

There are also uncertainties regarding the interpretation and application of current and future PRC laws, regulations and rules regarding the status of the rights of our Cayman Islands holding company with respect to the contractual arrangements. It is uncertain whether our corporate structure will be seen as violating the foreign investment rules as we are currently leveraging the contractual arrangements to operate businesses which are classified as VATS by the PRC government and are prohibited or restricted to foreign investment. Furthermore, if future legislation mandates further actions to be taken by companies with respect to existing contractual arrangements, we may face uncertainties as to whether we can complete such actions in a timely manner, or at all. If we fail to take appropriate and timely measures to comply with any of these or similar regulatory compliance requirements, our current corporate structure, corporate governance, and business operations could be materially and adversely affected. Further, if our corporate structure or contractual arrangements were found to be in violation of any existing or future PRC laws or regulations, we could be subject to severe penalties, and the relevant regulatory authorities would have discretion in dealing with such violations. As a result, we would be unable to direct the activities of the consolidated VIEs and their subsidiaries, receive their economic benefits and/or claim our contractual control rights over the assets of the VIEs and their subsidiaries that conduct substantially all of our operations in mainland China, we would no longer be able to consolidate such VIEs and their subsidiaries in our consolidated financial statements in accordance with U.S. GAAP, which would likely materially and adversely affect our financial condition and results of operations, and cause the value of our securities to significantly decline or become worthless. See “Item 3. Key Information — D. Risk Factors — Risks Related to Our Corporate Structure — If the PRC government deems that the contractual arrangements in relation to the consolidated VIEs do not comply with PRC regulatory restrictions on foreign investment in the relevant industries, or if these regulations or the interpretation of existing regulations change in the future, we may be subject to severe penalties or be forced to relinquish our interests in the operations of the consolidated VIEs and their subsidiaries” and “Item 3. Key Information — D. Risk Factors — Risks Related to Our Corporate Structure — Uncertainties exist with respect to the interpretation and implementation of the 2019 PRC Foreign Investment Law and how it may impact the viability of our current corporate structure, corporate governance and business operations” in our 2024 Annual Report.

The PRC government’s authority in regulating our operations, as well as its oversight over offerings conducted overseas by, and foreign investment in, China-based issuers, could impact our ability to offer or continue to offer securities to investors. Implementation of industry-wide regulations of this nature may cause the value

of our securities to significantly decline or become worthless. For more details, see “Item 3. Key Information — D. Risk Factors — Risks Related to Doing Business in the People’s Republic of China — Our business operations are impacted by the policies and regulations of the PRC government. Any policy or regulatory change may cause us to incur compliance costs” and “Item 3. Key Information — D. Risk Factors — Risks Related to Doing Business in the People’s Republic of China — We face various legal and operational risks and uncertainties as a company based in and primarily operating in China” in our 2024 Annual Report.

The complex and changing regulatory environment in mainland China could cause material adverse changes in our operations and the value of our ADSs. For more details, see “Item 3. Key Information — D. Risk Factors — Risks Related to Doing Business in the People’s Republic of China — The complex and changing regulatory environment in mainland China as well as changes in policies, laws, rules and regulations in the PRC could adversely affect us” in our 2024 Annual Report.

Permissions Required from the PRC Authorities for Our Operations and this Offering

We conduct our business primarily through our subsidiaries, the consolidated VIEs and their subsidiaries in mainland China. Our operations in mainland China are governed by PRC laws and regulations. As of the date of this prospectus supplement, our mainland China subsidiaries, the consolidated VIEs and their subsidiaries have obtained the requisite licenses and permits from the PRC government authorities that are material for the business operations of our subsidiaries, the consolidated VIEs and their subsidiaries in mainland China, including, among others, the VATS licenses, fixed-asset investment project filings and energy conservation review opinions. Given the uncertainties of interpretation and implementation of relevant laws and regulations and the enforcement practice by relevant government authorities, we may be required to obtain additional licenses, permits, filings or approvals for our business in the future.

We completed the pre-issuance registration with the NDRC in connection with the convertible notes offering and obtained a certificate evidencing such registration on April 7, 2025. After the issuance of the notes, we shall file or cause to be filed the requisite information on the convertible notes offering with the NDRC within the time period as required by the NDRC pursuant to the NDRC Foreign Debt Measures and any implementation rules or applicable policies as issued by the NDRC from time to time. In addition, as advised by our PRC legal counsel, King & Wood Mallesons, according to the Trial Administrative Measures of Overseas Securities Offering and Listing by Domestic Companies issued by the CSRC on February 17, 2023, we are required to submit a filing with the CSRC within three business days after completion of the convertible notes offering. We cannot assure you that we will be able to complete the filing procedures as required in a timely manner. For details of the associated risks, see “Risk Factors — Risks Relating to Doing Business in the People’s Republic of China — The approval of, or filing with the CSRC or other PRC government authorities may be required in connection with acquisitions conducted by foreign investors or future offshore offerings under PRC law, and, if required, we cannot predict whether or for how long it will take to obtain such approval or complete such filing” in Exhibit 99.3 to the May 27 Form 6-K.

Cash Flows through our Organization

GDS Holdings Limited is a holding company with no material operations of its own. As a result, although other means are available for us to obtain financing at the holding company level, our company’s ability to pay dividends to the shareholders and to service any debt it may incur may depend upon dividends paid by our subsidiaries. We conduct our operations primarily through our subsidiaries and consolidated VIEs and their subsidiaries. In addition, we hold a significant equity interest in DayOne, our former consolidated subsidiary and current equity investee company. GDS Holdings Limited provides continuing financial support to our subsidiaries for business expansion, while our subsidiaries also obtain financings through borrowings from various financial institutions. Meanwhile, for compliance purpose, the VIEs and their subsidiaries are the contracting party for our IDC service agreements, and our subsidiaries, as the owners of most of the self-developed data center assets, provide outsourcing and other services to the VIEs. Once the VIEs and their subsidiaries receive service fees from the customers, they can settle the corresponding outsourcing and service fees to our subsidiaries accordingly. For more details, see “Item 5. Operating and Financial Review and Prospects — B. Liquidity and Capital Resources” in our 2024 Annual Report.

Non-GAAP Measures

In evaluating our business, we consider and use the following non-GAAP measures as supplemental measures to review and assess our operating performance:

	RMB		RMB		RMB		US$		RMB		RMB		US$

Non-GAAP Consolidated Financial Data:
Adjusted EBITDA(1)		4,333,724		4,733,004		4,876,436		671,991		1,140,716		1,323,847		182,430
Adjusted EBITDA margin(2)		46.8%		48.4%		47.2%		47.2%		46.9%		48.6%		48.6%
Adjusted gross profit(3)		4,788,629		5,087,630		5,314,174		732,313		1,270,130		1,455,422		200,562
Adjusted gross profit margin(4)		51.7%		52.0%		51.5%		51.5%		52.2%		53.4%		53.4%

(1)

Adjusted EBITDA is defined as net income or net loss (computed in accordance with GAAP) excluding income (loss) from discontinued operations, net interest expenses, income tax expenses (benefits), depreciation and amortization, operating lease cost relating to prepaid land use rights, accretion expenses for asset retirement costs, share-based compensation expenses, gain on deconsolidation of subsidiaries, share of results of equity method investees, gain from purchase price adjustment and impairment losses of long-lived assets.

(2)

Adjusted EBITDA margin is defined as adjusted EBITDA as a percentage of net revenue.

(3)

Adjusted gross profit is defined as gross profit (computed in accordance with U.S. GAAP), excluding depreciation and amortization, operating lease cost relating to prepaid land use rights, accretion expenses for asset retirement costs and share-based compensation expenses allocated to cost of revenue.

(4)

Adjusted gross profit margin is defined as adjusted gross profit as a percentage of net revenue.

Our management and board of directors use adjusted EBITDA, adjusted EBITDA margin, adjusted gross profit, and adjusted gross profit margin, which are non-GAAP financial measures, to evaluate our operating performance, establish budgets and develop operational goals for managing our business. We believe that the exclusion of the income and expenses eliminated in calculating adjusted EBITDA and adjusted gross profit can provide useful supplemental measures of our core operating performance. In particular, we believe that the use of adjusted EBITDA as a supplemental performance measure captures the trend in our operating performance by excluding from our operating results the impact of our capital structure (primarily interest expense), asset base charges (primarily depreciation and amortization, operating lease cost relating to prepaid land use rights and accretion expenses for asset retirement costs), other non-cash expenses (primarily share-based compensation expenses), and other income and expenses which we believe are not reflective of our operating performance (primarily gain or loss from deconsolidation of subsidiaries, share of results of equity method investees and gain from purchase price adjustment), whereas the use of adjusted gross profit as a supplemental performance measure captures the trend in gross profit performance of our data centers in service by excluding from our gross profit the impact of asset base charges (primarily depreciation and amortization, operating lease cost relating to prepaid land use rights and accretion expenses for asset retirement costs) and other non-cash expenses (primarily share-based compensation expenses) included in cost of revenue. In addition, we exclude income (loss) from discontinued operation from our adjusted EBITDA and adjusted EBITDA margin to measure our financial performance from continuing operations, which will be consistent with our future financial performance measurements.

We note that depreciation and amortization is a fixed cost which commences as soon as each data center enters service. However, it usually takes several years for new data centers to reach high levels of utilization and profitability. We incur significant depreciation and amortization costs for its early stage data center assets. Accordingly, gross profit, which is a measure of profitability after taking into account depreciation and amortization, does not accurately reflect the Company’s core operating performance.

We also present these non-GAAP measures because we believe these non-GAAP measures are frequently used by analysts, investors and other interested parties as measures of the financial performance of companies in our industry.

TABLE OF CONTENTS

These non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. These non-GAAP financial measures have limitations as analytical tools, and when assessing our operating performance, cash flows or our liquidity, investors should not consider them in isolation, or as a substitute for net income (loss), cash flows (used in) provided by operating activities or other consolidated statements of operations and cash flow data prepared in accordance with U.S. GAAP. There are a number of limitations related to the use of these non-GAAP financial measures instead of their nearest GAAP equivalent. First, adjusted EBITDA, adjusted EBITDA margin, adjusted gross profit, and adjusted gross profit margin are not substitutes for gross profit, net income (loss), cash flows (used in) provided by operating activities or other consolidated statements of operation and cash flow data prepared in accordance with U.S. GAAP. Second, other companies may calculate these non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of these non-GAAP financial measures as tools for comparison. Finally, these non-GAAP financial measures do not reflect the impact of net interest expenses, income tax benefits (expenses), depreciation and amortization, operating lease cost relating to prepaid land use rights, accretion expenses for asset retirement costs, share-based compensation expenses, gain from purchase price adjustment, impairment losses of long-lived assets, gain on deconsolidation of subsidiaries and share of results of equity method investees, each of which has been and may continue to be incurred in our business.

We mitigate these limitations by reconciling the non-GAAP financial measure to the most comparable U.S. GAAP performance measure, all of which should be considered when evaluating our performance.

The following table reconciles our adjusted EBITDA in the periods presented to the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP, which is net income or net loss:

THE OFFERING

Issuer

GDS Holdings Limited, an exempted company incorporated under the laws of the Cayman Islands.

Initial Offering price

US$ per ADS, which is the same price as the price to the public per ADS in the Concurrent Primary ADSs Offering (as described below)

Securities offered; Delta Placement of Borrowed ADSs

An affiliate of the ADS Borrower (the “Borrowed ADS Underwriter”) is selling short Borrowed ADSs (representing Class A ordinary shares) to facilitate privately negotiated derivative transactions, by which certain investors in our % convertible senior notes due 2032 (“convertible senior notes”) in the Concurrent Notes Offering described below, who employ a convertible arbitrage strategy, will hedge their market risk with respect to the convertible senior notes. These derivative transactions are expected to be on market-standard terms for such type of transactions. During the term of such transactions, such investors may use their synthetic short positions established thereunder at their sole discretion. The number of Borrowed ADSs to be sold hereunder will depend on what portion of investors in the Concurrent Notes Offering desire to hedge their investments through the derivative transactions with the ADS Borrower or its affiliates, will be determined at the time of pricing of the Delta Placement of Borrowed ADSs, and is expected to be no greater than commercially reasonable initial short positions of such convertible arbitrage investors. We do not expect to lend any additional ADSs to the ADS Borrower or any other party to facilitate any short positions that may be desired by any initial or subsequent investors in the convertible senior notes after this offering, and will not lend any additional ADSs following any exercise by the initial purchasers in the concurrent convertible notes offering described below of their option to purchase additional convertible senior notes. There can be no assurance that the ADS Borrower will continue to facilitate any privately negotiated derivative transactions by which any convertible arbitrage investors in our convertible senior notes may be hedging their exposure to the market risk of our ADSs and/or Class A ordinary shares during the term of such convertible senior notes. There is no intent that the Delta Placement of Borrowed ADSs will create any inventory of our ADSs and/or Class A ordinary shares with the ADS Borrower or its affiliates that could be made available for borrowing to any investor in our convertible senior notes during the term thereof

We believe that under United States generally accepted accounting principles, or U.S. GAAP, the Borrowed ADSs will not be considered outstanding for the purpose of computing and reporting our earnings per ADS. We will not receive any proceeds from the sale of the Borrowed ADSs in this offering, but we will receive from the ADS Borrower or its affiliate a nominal lending fee of US$0.0004 per each Borrowed ADS. The ADS Borrower or its affiliates will receive all the proceeds from the sale of the Borrowed ADSs.

TABLE OF CONTENTS

Concurrent Notes Offering

Concurrently with the Delta Placement of Borrowed ADSs, we are offering US$450,000,000 aggregate principal amount of convertible senior notes, plus up to US$50,000,000 aggregate principal amount of our convertible senior notes if the initial purchasers of the Concurrent Notes Offering exercise their option to purchase additional convertible senior notes in full, pursuant to a separate offering memorandum in reliance on the exemptions from registration provided by Rule 144A under the Securities Act. Neither this prospectus supplement nor the accompanying prospectus is an offer in respect of our convertible senior notes.

We estimate that the net proceeds to us from the Concurrent Notes Offering, if it is consummated, will be approximately US$ million (or approximately US$ million if the initial purchasers in the Concurrent Notes Offering if the initial purchasers of the Concurrent Notes Offering exercise their option to purchase additional convertible senior notes in full), after deducting the initial purchasers’ discounts and commissions and our estimated offering expenses. We expect to use the net proceeds of the Concurrent Notes Offering for working capital needs and the refinancing of its existing indebtedness, including potential future negotiated repurchases, or redemption upon exercise of the investor put right, of its convertible bonds due 2029.

See “Description of the Delta Placement of Borrowed ADSs and Concurrent Offering of Convertible Senior Notes” for a description of the Concurrent Notes Offering.

Concurrent Primary ADS Offering

Concurrently with this offering and the Concurrent Notes Offering, we are also offering 5,200,000 (or 5,980,000 ADSs if the underwriters in the Concurrent Primary ADS Offering exercise their option to purchase additional ADSs in full) ADSs pursuant to a separate prospectus supplement and the accompanying prospectus in the Concurrent Primary ADS Offering. We will receive all of the net proceeds from the offering of the Primary ADSs. This prospectus supplement is not an offer in respect of the Primary ADSs which will be made under a separate prospectus supplement filed with the SEC pursuant to Rule 424(b) of the Securities Act and the base prospectus. We estimate that the net proceeds to us from the Concurrent Primary ADS Offering, if it is consummated, will be approximately US$ million (or approximately US$ million if the underwriters in the Concurrent Primary ADS Offering if the underwriters of the Concurrent Primary ADS Offering exercise their option to purchase additional ADSs in full), after deducting the initial purchasers’ discounts and commissions and our estimated offering expenses. We expect to use the net proceeds of the Concurrent Primary ADS Offering for working capital needs and the refinancing of its existing indebtedness, including potential future negotiated repurchases, or redemption upon exercise of the investor put right, of its convertible bonds due 2029.

TABLE OF CONTENTS

Listing

Our ADSs are listed on The Nasdaq Global Market under the symbol “GDS” and our Class A ordinary shares are listed on the Main Board of the Hong Kong Stock Exchange under the stock code “9698.”

Lock-up

We and our officers, directors and certain principal shareholders have agreed not to sell or otherwise dispose of our ordinary shares, ADSs or certain other securities until the expiration of the Restricted Periods described under “Underwriting (Conflicts of Interest).”

Risk factors

An investment in our ADSs involves risks. You should carefully consider the information set forth in the sections of this prospectus supplement and the accompanying prospectus titled “Risk Factors,” as well as other information included in or incorporated by reference into this prospectus supplement and the accompanying prospectus before deciding whether to invest in the ADSs.

Delayed Settlement

We expect that delivery of the Borrowed ADSs will be made against payment therefor on , 2025 (such settlement being referred to as “T+2”). Under Rule 15c6-1 under the Securities Exchange Act of 1934 (the “Exchange Act”), as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the ADSs more than one business day prior to , 2025 will be required, by virtue of the fact that the Borrowed ADSs settle on T+2 to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Borrowed ADSs who wish to trade the Borrowed ADSs during such period should consult their advisor.

Conflicts of interest

All of the proceeds of the offering of the Borrowed ADSs will be paid to the Borrowed ADS Underwriter or affiliates thereof. As a result, the Borrowed ADS Underwriter, or affiliates thereof, will each receive 5% or more of the net proceeds of this offering. Thus, the Borrowed ADS Underwriter has a “conflict of interest” as defined in Rule 5121 of the Financial Industry Regulatory Authority, Inc. (“FINRA”). Accordingly, this offering will be made in compliance with the requirements of FINRA Rule 5121. The appointment of a “qualified independent underwriter” is not required in connection with this offering as a “bona fide public market”, as defined in FINRA Rule 5121, exists for the ADSs.

RISK FACTORS

Investing in the ADSs involves risk. You should consider carefully the risks described below, in our 2024 Annual Report and all of the other information set forth in or incorporated by reference into this prospectus supplement and in the accompanying prospectus before investing in the ADSs. The following factors, individually and in the aggregate, could cause our business, results of operations and financial condition to suffer or materially differ from expected and historical results. As a result, the trading price of the ADSs may decline, and you may lose part or all of your investment.

Risks Relating to Doing Business in the People’s Republic of China

Substantially all of our operations are conducted in the PRC and a substantial majority of our net revenue is sourced from the PRC. Accordingly, our financial condition and results of operations are affected to a significant extent by economic, political and legal developments in the PRC.

The PRC economy differs from the economies of most developed countries in many respects, including the extent of government involvement, level of development, growth rate, and control of foreign exchange and allocation of resources. Although the PRC government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets, and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in mainland China is still owned by the government. In addition, the PRC government continues to play a significant role in regulating industry development by imposing industrial policies. The PRC government drives China’s economic growth by allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy, regulating financial services and institutions and providing preferential treatment to particular industries or companies.

While the PRC economy has experienced significant growth in the past three decades, such growth has been uneven, both geographically and among various sectors of the economy. The PRC government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures may benefit the overall PRC economy, but may also have a negative effect on us. Our financial condition and results of operation could be materially and adversely affected by government control over capital investments or changes in tax regulations that are applicable to us. See “— The complex and changing regulatory environment in mainland China as well as changes in policies, laws, rules and regulations in the PRC could adversely affect us.” In addition, the PRC government has implemented in the past certain measures to control the pace of economic growth. These measures may cause decreased economic activity, which in turn could lead to a reduction in demand for our services and consequently have a material adverse effect on our businesses, financial condition and results of operations.

We face various legal and operational risks and uncertainties as a company based in and primarily operating in China.

We face various legal and operational risks and uncertainties as a company based in and primarily operating in China. The PRC government has authority to exert influence on the ability of a China-based company, like us, to conduct its business, accept foreign investments or list on a U.S. stock exchange. For example, we face risks associated with regulatory approvals of offshore offerings, anti-monopoly regulatory actions, cybersecurity and data privacy, as well as any future inability of the U.S. PCAOB to inspect or investigate our auditors completely. In addition, the PRC government may also intervene with or influence our operations as the government deems appropriate to further regulatory, political and societal goals. The PRC government has published new policies that affected certain industries such as the education and internet industries, and we cannot rule out the possibility that it may in the future release regulations or policies regarding our industry that could affect our business, financial condition and results of operations. See “— Complex and changing regulatory environment in the mainland China, and changes in policies, laws, rules and regulations in the PRC that could adversely affect us.” Any such regulatory oversight actions, once taken by the PRC government,

S-21

TABLE OF CONTENTS

could impact our ability to offer or continue to offer securities to investors, and could cause the value of our securities, including our ADSs, to significantly decline or become worthless.

The complex and changing regulatory environment in mainland China as well as changes in policies, laws, rules and regulations in the PRC could adversely affect us.

Substantially all of our operations are conducted in mainland China, and are governed by PRC laws, rules and regulations. Our mainland China subsidiaries, the VIEs and their subsidiaries are subject to laws, rules and regulations applicable to foreign investment in mainland China. The PRC legal system is a civil law system based on written statutes. Unlike the common law system, prior court decisions may be cited for reference but have limited precedential value under the civil law system.

In 1979, the PRC government began to promulgate a comprehensive system of laws, rules and regulations governing economic matters in general. The overall effect of legislation over the past three decades has significantly enhanced the protections afforded to various forms of foreign investment in mainland China. However, enacted laws, rules and regulations may not sufficiently cover all aspects of economic activities in mainland China or may be subject to degrees of interpretation by PRC regulatory agencies. Any failure or perceived failure to comply with the related laws, rules and regulations, by us or our top customers, may result in governmental investigations or enforcement actions, litigations or claims against us or our top customers and could have an adverse effect on our business, financial condition and results of operations.

Any administrative and court proceedings in mainland China may be protracted, resulting in costs and diversion of resources and management attention. Since PRC administrative and court authorities have discretion in interpreting and implementing statutory and contractual terms, it may be difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy. These uncertainties may impede our ability to enforce the contracts we have entered into and could materially and adversely affect our business, financial condition and results of operations.

Our business operations are impacted by the policies and regulations of the PRC government. Any policy or regulatory change may cause us to incur compliance costs.

We are subject to national, provincial and local governmental regulations, policies and controls. Central governmental authorities and provincial and local authorities and agencies regulate many aspects of Chinese industries, including without limitation, among others and in addition to specific industry-related regulations, the following aspects:

•

construction or development of new data centers or renovation, rebuilding or expansion of existing data centers;

•

banking regulations, as a result of the colocation services we provide to banks and financial institutions, including regulations governing the use of subcontractors in the management and maintenance of facilities;

•

environmental protection laws and regulations;

•

security laws and regulations;

•

establishment of or changes in shareholder of foreign investment enterprises;

•

foreign exchange;

•

taxes, duties and fees;

•

customs;

•

land planning and land use rights;

•

energy conservation and emission reduction;

•

cybersecurity and information protection laws and regulations, including the Cybersecurity Law of the People’s Republic of China, or the Cybersecurity Law, the Data Security Law of the People’s Republic of China, or the Data Security Law, and the Administrative Measures for the Graded Protection of Information Security; and

S-22

TABLE OF CONTENTS

•

artificial intelligence laws and regulations.

The liabilities, costs, obligations and requirements associated with these laws and regulations may be material, may delay the commencement of operations at our new data centers or cause interruptions to our operations. Failure to comply with the relevant laws and regulations in our operations may result in various penalties, including, among others the suspension of our operations and thus adversely and materially affect our business, prospects, financial condition and results of operations. While we have endeavored to comply with the relevant laws and regulations in the development and operation of our data centers, we may incur additional costs in order to fulfill such requirements, and we cannot assure you that we have complied with, or will comply with the requirements of all relevant laws and regulations (including obtaining of all relevant approvals required for the development and operation of data centers). Additionally, there can be no assurance that currently applicable laws or regulations will remain unchanged or no new laws or regulations will be imposed. For example, see “Item 4. Information on the Company — B. Business Overview — Regulatory Matters Related to Our Business — People’s Republic of China Regulations — Regulations Related to Information Technology Outsourcing Services Provided to Banking Financial Institutions” in our 2024 Annual Report for information regarding regulations of banking and financial institutions that outsource their data center services to us, and “— Regulations Related to Land Use Rights and Construction” in our 2024 Annual Report for information regarding restrictions on the new construction or expansion of data centers within the boundaries of the Beijing municipality. We cannot assure you that we will comply with the requirements of all new laws and regulations. For example, the PRC Civil Code, which was passed on May 28, 2020 by the National People’s Congress and became effective in January 2021, replaces among other laws, the General Provisions of the PRC Civil Law, the PRC Marriage Law, the PRC Guarantee Law, the PRC Contract Law, the PRC Property Law and the PRC Tort Liability Law. It remains to be seen how the PRC Civil Code will be implemented and enforced in practice. In addition, in March 2021, the National People’s Congress published the Fourteenth Five-Year Plan for the National Economic and Social Development of the People’s Republic of China and the Outline of the Long-term Goals for 2035, according to which the PRC government aims to reach the goal of achieving net-zero carbon dioxide emissions by offsetting emissions of carbon dioxide by 2060, namely carbon neutrality, through various measures including afforestation, energy conservation and emission reduction. To achieve the carbon neutrality goal, the PRC government has promulgated certain regulations and may promulgate more laws and regulations in the future. For example, the Circular 1258 provides that with the consumption of the power generated from renewable energy sources in 2020 in all regions as the base, the consumption of the power generated from renewable energy sources (mainly includes wind energy, solar energy, hydropower, biomass power and geothermal energy) newly added each year compared with the previous year during the Fourteenth Five-Year Plan period shall be deducted at the time of assessment of total national and regional energy consumption, which is an important measure for the “Dual-Control” targets. These laws and regulations may compel us to source more renewable energy, and we may be unable to do on commercially acceptable terms. Compliance with such laws or regulations may require us to incur material capital expenditures or other obligations or liabilities.

The PRC Cybersecurity Law and Data Security Law are relatively new, and subject to change and uncertain interpretation by regulators. These laws may result in claims, penalties, changes to our business practices, increased cost of operations, damages to our reputation and brand, or otherwise harm our business.

Additionally, the Cybersecurity Law came into effect on June 1, 2017, which provides certain rules and requirements applicable to network service providers in mainland China. The Cybersecurity Law requires network operators to perform certain functions related to cybersecurity protection and the strengthening of network information management through taking technical and other necessary measures as required by laws and regulations to safeguard the operation of networks, responding to network security effectively, preventing illegal and criminal activities, and maintaining the integrity and confidentiality and usability of network data. However, the Cybersecurity Law still leaves a series of gaps to be filled due to the complex and sensitive nature of this regulatory area. While the Cybersecurity law sets out a broad set of principles, certain key terms and clauses are uncertain and ambiguous, which appear intended to be clarified through a series of laws, implementing regulations and guidelines to be issued by relevant authorities. Numerous regulations, guidelines and other measures have been and are expected to be adopted under the Cybersecurity Law. For more details, see “Item 4. Information on the Company — B. Business Overview — Regulatory Matters Related to Our Business — People’s Republic of China Regulations — Regulations Related to Information Security and

S-23

TABLE OF CONTENTS

Confidentiality of User Information” in our 2024 Annual Report. Currently, the Cybersecurity Law and relevant regulations, guidelines and other measures have not directly impacted our operations, but in light of rapid advances in its implementation, we believe the implementation of the Cybersecurity Law involves potential risks to our business because we may be deemed as the network operator of critical information infrastructure thereunder.

Furthermore, the PRC regulatory and enforcement regime with regard to data security and data protection has continued to evolve. There are uncertainties on how certain laws and regulations will be implemented in practice. PRC regulators have been increasingly focused on regulating data security and data protection. We expect that these areas will receive greater attention from regulators, as well as attract public scrutiny and attention going forward. This greater attention, scrutiny and enforcement, including more frequent inspections, could increase our compliance costs and subject us to heightened risks and challenges associated with data security and protection. As of the date of this prospectus supplement, we have not been designated as operator of critical information infrastructure by the PRC governmental authorities. While we do not have access to our customers’ data stored on the servers collocated in our data centers, we cannot rule out the possibility that data related to our operations may be deemed important data/core data or we may be deemed to be a critical information infrastructure operator, which would subject us to additional supervisory requirements. Any incompliance on such additional supervisory requirements may subject us to fines, order to rectify, suspension of users registration, revocation of business certificate and other penalties, which may have material adverse effect on our business, operations and financial condition as well as the price of our securities.

In addition, we could become subject to enhanced cybersecurity review or investigations launched by PRC regulators in the future. The Data Security Law provides that the state shall establish a data security review mechanism on data processing activities that do or may affect national security. Pursuant to the Cybersecurity Review Measures effective on February 15, 2022, critical information infrastructure operators that procure internet products and services must be subject to the cybersecurity review if their activities affect or may affect national security and network platform operators that hold personal information of over one million users shall apply with the Cybersecurity Review Office for a cybersecurity review before any public listing in a foreign country. For more details, please see “Item 4. Information on the Company — B. Business Overview — Regulatory Matters Related to Our Business — People’s Republic of China Regulations — Regulations Related to Information Security and Confidentiality of User Information” in our 2024 Annual Report. Any failure or delay in the completion of the cybersecurity review procedures or any other non-compliance with the cybersecurity related laws and regulations may result in fines or other penalties, including suspension of business, website closure, and revocation of prerequisite licenses, as well as reputational damage or legal proceedings or actions against us, which may have material adverse effect on our business, financial condition or results of operations. As of the date of this prospectus supplement, we have not been informed by any PRC governmental authority of any requirement that we file for a cybersecurity review. We have not been involved in any investigations on cybersecurity review initiated by the CAC or other competent authorities, and we have not received any inquiry, notice, warning, or sanction in such respect. However, there remains significant uncertainty in the interpretation and enforcement of relevant PRC cybersecurity laws and regulations. We cannot assure you that our future offering will be subject to cybersecurity review by the CAC or other competent authorities, and if so, we may not be able to pass such review.

We believe that we are in compliance with the regulations and policies that have been issued by the CAC and other competent PRC regulatory authorities on cybersecurity in all material respects as of the date of this prospectus supplement. We have formulated a cybersecurity management policy and information security management guidelines to comply with the requirements under the Cybersecurity Law. See “Item 16K. Cybersecurity” in our 2024 Annual Report for details on measures we have taken to manage information security risk. However, we cannot assure you that the measures we have taken or will take are adequate under the Cybersecurity Law or other cybersecurity related laws and regulations, and we may be held liable in the event of any breach of the relevant requirements under the Cybersecurity Law or other relevant laws and regulations. Furthermore, as uncertainties remain regarding the interpretation and implementation of applicable PRC laws and regulations, we cannot assure you that we will comply with such laws and regulations in all respects and we may be ordered to rectify or terminate any actions that are deemed illegal by regulatory authorities. We may also become subject to fines and/or other sanctions which may have material adverse effect on our business, operations and financial condition as well as price of our securities.

We may also be held liable in the event of any breach of general clauses on our compliance with such statutory requirements as well as some other specific requirements related to data protection under the relevant customer contracts. If further changes in our business practices are required under China’s evolving regulatory framework for the protection of information in cyberspace, our business, financial condition and results of operations may be adversely affected.

The approval of, or filing with the CSRC or other PRC government authorities may be required in connection with acquisitions conducted by foreign investors or future offshore offerings under PRC law, and, if required, we cannot predict whether or for how long it will take to obtain such approval or complete such filing.

The M&A Rules include, among other things, provisions that purport to require that an offshore special purpose vehicle formed for the purpose of an overseas listing of securities in a PRC company obtain the approval of the CSRC prior to the listing and trading of such special purpose vehicle’s securities on an overseas stock exchange. On September 21, 2006, the CSRC published on its official website procedures regarding its approval of overseas listings by special purpose vehicles. However, uncertainty remains regarding the scope and applicability of the M&A Rules to offshore special purpose vehicles.

While the application of the M&A Rules remains unclear, we believe, based on the advice of our PRC counsel, King & Wood Mallesons, that the CSRC approval was not required in the context of our initial public offering or follow-on public offerings under the M&A Rules because we had not acquired any equity interests or assets of a PRC company owned by its Controlling Shareholders or beneficial owners who are PRC companies or individuals, as such terms are defined under the M&A Rules. There can be no assurance that the PRC regulatory authorities will not take a view that is contrary to or otherwise different from the above opinions of our PRC counsel in the future. If any other PRC regulatory body subsequently determines that its approval was needed for our initial public offering or follow-on public offerings or such approval is needed for any future offerings, we may face actions or sanctions by the CSRC or other PRC regulatory agencies. In any such event, these regulatory agencies may impose fines and penalties on our operations in mainland China, limit our operating privileges in mainland China, delay or restrict the repatriation of the proceeds from our initial public offering or follow-on public offerings into the PRC or take other actions that could have a material adverse effect on our business, financial condition, results of operations, reputation and prospects, as well as the trading price of our ADSs and/or ordinary shares.

The regulations also established additional procedures and requirements that are expected to make merger and acquisition activities in mainland China by foreign investors more time-consuming and complex, including requirements in some instances that MOFCOM be notified in advance of any change-of-control transaction in which a foreign investor takes control of a PRC domestic enterprise, or that the approval from MOFCOM be obtained in circumstances where overseas companies established or controlled by PRC enterprises or residents acquire affiliated domestic companies. We may grow our business in part by acquiring other companies operating in our industry. Complying with the requirements of the new regulations to complete such transactions could be time-consuming, and any required approval processes, including approval from MOFCOM, may delay or inhibit our ability to complete such transactions, which could affect our ability to expand our business or maintain our market share. See “Item 4. Information on the Company-B. Business Overview-Regulatory Matters Related to Our Business -People’s Republic of China Regulations-Regulations Related to M&A and Overseas Listings” in our 2024 Annual Report.

On February 17, 2023, the CSRC released several regulations regarding the filing requirements for overseas offerings and listings by domestic companies, including the Trial Administrative Measures of Overseas Securities Offering and Listing by Domestic Companies, or the Trial Measures, and five supporting guidelines, or together with the Trial Measures, the New Regulations on Filing. The New Regulations on Filing were formally implemented on March 31, 2023. The New Regulations on Filing provides, among others, that PRC domestic companies that seek to offer and list securities in overseas markets, either in direct or indirect means, are required to file the required documents with the CSRC within three working days after the application for overseas listing submitted. However, listed companies like us, which are called as “the stock enterprises”, are not required to apply for the filing immediately until they involved in matters required filings, such as follow-on financing activities. For details about the Trial Measures, please refer to “Item 4. Information on the Company — B. Business Overview — Regulatory Matters Related to Our Business — People’s Republic of China Regulations — Regulations Related to M&A and Overseas Listings” in our 2024 Annual Report.

TABLE OF CONTENTS

If it is determined in the future that approval and filing from the CSRC or other regulatory authorities or other procedures, including the cybersecurity review under the Cybersecurity Review Measures, are required for our offshore offerings, it is uncertain whether we can or how long it will take us to obtain such approval or complete such filing procedures and any such approval or filing could be rejected. Any failure to obtain (including possible rescission of such approval) or delay in obtaining such approval or completing such filing procedures for our offshore offerings, or a rescission of any such approval or filing if obtained by us, would subject us to sanctions by the CSRC or other PRC regulatory authorities for failure to seek CSRC approval or filing or other government authorization for our offshore offerings. These regulatory authorities may impose fines and penalties on our operations in mainland China, limit our ability to pay dividends outside of mainland China, limit our operating privileges in mainland China, delay or restrict the repatriation of the proceeds from our offshore offerings into mainland China or take other actions that could materially and adversely affect our business, financial condition, results of operations, and prospects, as well as the trading price of our listed securities. The CSRC or other PRC regulatory authorities also may require us to halt our offshore offerings before settlement and delivery of the shares offered. Consequently, if investors engage in market trading or other activities in anticipation of and prior to settlement and delivery, they do so at the risk that settlement and delivery may not occur. In addition, if the CSRC or other regulatory authorities later promulgate new rules or explanations requiring that we obtain their approvals or accomplish the required filing or other regulatory procedures for our prior offshore offerings, we may be unable to obtain a waiver of such approval requirements, if and when procedures are established to obtain such a waiver. Any uncertainties or negative publicity regarding such approval requirement could materially and adversely affect our business, prospects, financial condition, reputation, and the trading price of our listed securities.

PRC regulations relating to investments in offshore companies by PRC residents may subject our PRC-resident beneficial owners or our mainland China subsidiaries to liability or penalties, limit our ability to inject capital into our mainland China subsidiaries or limit our mainland China subsidiaries’ ability to increase their registered capital or distribute profits.

SAFE Circular 37, which replaced the former circular commonly known as “SAFE Circular 75” promulgated by SAFE on October 21, 2005, requires PRC residents to register with local branches of SAFE in connection with their direct establishment or indirect control of an entity, for the purpose of overseas investment and financing, with such PRC residents’ legally owned assets or equity interests in domestic enterprises or offshore assets or interests, referred to in SAFE Circular 37 as a “special purpose vehicle.” SAFE Circular 37 further requires amendment to the registration in the event of any significant changes with respect to the special purpose vehicle, such as increase or decrease of capital contributed by PRC individuals, share transfer or exchange, merger, division or other material event. In the event that a PRC shareholder holding interests in a special purpose vehicle fails to fulfill the required SAFE registration, the mainland China subsidiaries of that special purpose vehicle may be prohibited from making profit distributions to the offshore parent and from carrying out subsequent cross-border foreign exchange activities, and the special purpose vehicle may be restricted in its ability to contribute additional capital into its mainland China subsidiary. Moreover, failure to comply with the various SAFE registration requirements described above could result in liability under PRC law for evasion of foreign exchange controls. According to the Notice on Further Simplifying and Improving Policies for the Foreign Exchange Administration of Direct Investment released on February 13, 2015 by SAFE, local banks will examine and handle foreign exchange registration for overseas direct investment, including the initial foreign exchange registration and amendment registration, under SAFE Circular 37 from June 1, 2015.

Mr. Huang completed the initial SAFE registration pursuant to SAFE Circular 75 in 2012, and is in the process of applying for amendment of such registration. We have notified substantial beneficial owners of ordinary shares who we know are PRC residents of their filing obligation. Nevertheless, we may not be aware of the identities of all of our beneficial owners who are PRC residents. We do not have control over our beneficial owners and there can be no assurance that all of our PRC-resident beneficial owners will comply with SAFE Circular 37 and subsequent implementation rules, and there is no assurance that the registration under SAFE Circular 37 and any amendment will be completed in a timely manner or will be completed at all. The failure of our beneficial owners who are PRC residents to register or amend their foreign exchange registrations in a timely manner pursuant to SAFE Circular 37 and subsequent implementation rules, or the failure of future beneficial owners of our company who are PRC residents to comply with the registration procedures set forth in SAFE Circular 37 and subsequent implementation rules, may subject such beneficial

S-26

TABLE OF CONTENTS

owners or our mainland China subsidiaries to fines and legal sanctions. Failure to register or comply with relevant requirements may also limit our ability to contribute additional capital to our mainland China subsidiaries and limit our mainland China subsidiaries’ ability to distribute dividends to our company. These risks may have a material adverse effect on our business, financial condition and results of operations.

Any failure to comply with PRC regulations regarding our employee share incentive plan may subject the PRC plan participants or us to fines and other legal or administrative sanctions.

Pursuant to SAFE Circular 37, PRC residents who participate in share incentive plans in overseas non-publicly-listed companies due to their position as director, senior management or employees of the mainland China subsidiaries of the overseas companies may submit applications to SAFE or its local branches for the foreign exchange registration with respect to offshore special purpose companies. Our directors, executive officers and other employees who are PRC residents and who were granted options may follow SAFE Circular 37 to apply for the foreign exchange registration before our company became an overseas listed company. Since our company became an overseas listed company upon completion of our initial public offering, we and directors, executive officers and other employees of our mainland China subsidiaries, the VIEs and their subsidiaries and any individuals who have been granted options have been subject to the Notice on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly Listed Company, issued by SAFE in February 2012, or SAFE Circular 7, according to which, among others, employees, directors, supervisors and other management members of PRC companies participating in any stock incentive plan of an overseas publicly listed company who are domestic individuals as defined therein are required to register and make regular periodic filings with SAFE through a domestic qualified agent, which could be a mainland China subsidiary of such overseas listed company, and complete certain other procedures. One of our subsidiaries, as the domestic qualified agent, has completed the registration under SAFE Circular 7 for our share incentive plan and we are making efforts to comply with these requirements stipulated in SAFE Circular 7. Failure to complete the SAFE registrations or meet other requirements may subject relevant participants in our share incentive plan to fines and legal sanctions and may also limit the ability to make payment under our share incentive plan or receive dividends or sales proceeds related thereto, or our ability to contribute additional capital into our wholly-foreign owned enterprises in mainland China and limit our wholly-foreign owned enterprises’ ability to distribute dividends to us. We also face regulatory uncertainties that could restrict our ability to adopt additional share incentive plans for our directors and employees under PRC law.

It may be difficult for overseas regulators to conduct investigations or collect evidence within China.

There are significant legal and other obstacles in mainland China to providing information needed for regulatory investigations or litigation initiated by regulators outside mainland China. Although the authorities in mainland China may establish a regulatory cooperation mechanism with the securities regulatory authorities of another country or region to implement cross-border supervision and administration, such cooperation with the securities regulatory authorities in the Unities States involves uncertainty. Furthermore, according to Article 177 of the PRC Securities Law, or Article 177, which became effective in March 2020, no overseas securities regulator is allowed to directly conduct investigation, evidence collection and other activities within the territory of the PRC. While detailed interpretation of or implementation rules under Article 177 have yet to be promulgated, the inability for an overseas securities regulator to directly conduct investigation or evidence collection activities within mainland China may further increase difficulties faced by you in protecting your interests.

The enforcement of the Labor Contract Law of the People’s Republic of China, or the PRC Labor Contract Law, and other labor-related regulations in the PRC may increase our labor costs, impose limitations on our labor practices and adversely affect our business and our results of operations.

On June 29, 2007, the SCNPC enacted the PRC Labor Contract Law, which became effective on January 1, 2008 and was amended on December 28, 2012. The PRC Labor Contract Law introduces specific provisions related to fixed-term employment contracts, part-time employment, probation, consultation with labor unions and employee assemblies, employment without a written contract, dismissal of employees, severance, and collective bargaining, which together represent enhanced enforcement of labor laws and regulations. According to the PRC Labor Contract Law, an employer is obliged to sign an unfixed-term labor contract

S-27

TABLE OF CONTENTS

with any employee who has worked for the employer for ten consecutive years. Further, if an employee requests or agrees to renew a fixed-term labor contract that has already been entered into twice consecutively, the resulting contract must have an unfixed term, with certain exceptions. The employer must pay economic compensation to an employee where a labor contract is terminated or expires in accordance with the PRC Labor Contract Law, except for certain situations which are specifically regulated. In addition, the government has issued various labor-related regulations to further protect the rights of employees. According to such laws and regulations, employees are entitled to annual leave ranging from five to fifteen days and are able to be compensated for any untaken annual leave days in the amount of three times their daily salary, subject to certain exceptions. In the event that we decide to change our employment or labor practices, the PRC Labor Contract Law and its implementation rules may also limit our ability to effect those changes in a manner that we believe to be cost-effective. In addition, as the interpretation and implementation of these new regulations are still evolving, our employment practices may not be at all times deemed in compliance with the new regulations. If we are subject to severe penalties or incur significant liabilities in connection with labor disputes or investigations, our business and financial conditions may be adversely affected.

We rely to a significant extent on dividends and other distributions on equity paid by our principal operating subsidiaries to fund offshore cash and financing requirements.

We are a holding company and rely to a significant extent on dividends and other distributions on equity paid by our principal operating subsidiaries and on remittances from the VIEs, for our offshore cash and financing requirements, including the funds necessary to pay dividends and other cash distributions to our shareholders, fund intercompany loans, service any debt we may incur outside of mainland China and pay our expenses. When our principal operating subsidiaries or the VIEs incur additional debt, the instruments governing the debt may restrict their ability to pay dividends or make other distributions or remittances to us. Furthermore, the laws, rules and regulations applicable to our mainland China subsidiaries and certain other subsidiaries permit payments of dividends only out of their retained earnings, if any, determined in accordance with applicable accounting standards and regulations.

Under PRC laws, rules and regulations, each of our subsidiaries incorporated in mainland China is required to set aside at least 10% of its net income each year to fund certain statutory reserves until the cumulative amount of such reserves reaches 50% of its registered capital. These reserves, together with the registered capital, are not distributable as cash dividends. As a result of these laws, rules and regulations, our subsidiaries, VIEs and their subsidiaries incorporated in mainland China are restricted in their ability to transfer a portion of their respective net assets to their shareholders as dividends, loans or advances. As of March 31, 2025, the restricted net assets were RMB25,274.9 million (US$3,483.0 million), including those of the VIEs and their subsidiaries of RMB320.7 million (US$44.2 million) and our subsidiaries of RMB24,954.2 million (US$3,438.8 million), which mainly consisted of paid-in registered capital. In addition, registered share capital and capital reserve accounts are also restricted from withdrawal in the PRC, up to the amount of net assets held in each operating subsidiary.

Limitations on the ability of VIEs to make remittance to the wholly-foreign owned enterprise and on the ability of our subsidiaries to pay dividends to us could limit our ability to access cash generated by the operations of those entities, including to make investments or acquisitions that could be beneficial to our businesses, pay dividends to our shareholders or otherwise fund and conduct our business.

In January 2017, SAFE promulgated the Circular on Further Improving Reform of Foreign Exchange Administration and Optimizing Genuineness and Compliance Verification, or SAFE Circular 3, which stipulates several capital control measures with respect to the outbound remittance of profit from domestic entities to offshore entities, including (i) under the principle of genuine transactions, banks shall check board resolutions regarding profit distribution, original copies of tax filing records and audited financial statements; and (ii) domestic entities shall hold income to account for previous years’ losses before remitting any profits. Moreover, pursuant to SAFE Circular 3, domestic entities shall make detailed explanations of their sources of capital and utilization arrangements, and provide board resolutions, contracts and other proof when completing the registration procedures in connection with any outbound investment.

We may be treated as a resident enterprise for PRC tax purposes under the PRC Enterprise Income Tax Law, and we may therefore be subject to PRC income tax on our global income.

Under the PRC Enterprise Income Tax Law and its implementing rules, enterprises established under the laws of jurisdictions outside of mainland China with “de facto management bodies” located in mainland China

S-28

TABLE OF CONTENTS

may be considered PRC tax resident enterprises for tax purposes and may be subject to the PRC enterprise income tax at the rate of 25% on their global income. “De facto management body” refers to a managing body that exercises substantive and overall management and control over the production and business, personnel, accounting books and assets of an enterprise. The STA issued Circular 82 on April 22, 2009. Circular 82 provides certain specific criteria for determining whether the “de facto management body” of a Chinese-controlled offshore-incorporated enterprise is located in mainland China. Although Circular 82 only applies to offshore enterprises controlled by PRC enterprises, not those controlled by foreign enterprises or individuals, the determining criteria set forth in Circular 82 may reflect the STA general position on how the “de facto management body” test should be applied in determining the tax resident status of offshore enterprises, regardless of whether they are controlled by PRC enterprises. If we were to be considered a PRC resident enterprise, we would be subject to PRC enterprise income tax at the rate of 25% on our global income. In such case, our profitability and cash flow may be materially reduced as a result of our global income being taxed under the Enterprise Income Tax Law. We believe that none of our entities outside of mainland China is a PRC resident enterprise for PRC tax purposes. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the interpretation of the term “de facto management body.”

We may not be able to obtain certain benefits under the relevant tax treaty on dividends paid by our mainland China subsidiaries to us through our Hong Kong subsidiary.

We are a holding company incorporated under the laws of the Cayman Islands and as such rely on dividends and other distributions on equity from our mainland China subsidiaries to satisfy part of our liquidity requirements. Pursuant to the PRC Enterprise Income Tax Law, a withholding tax rate of 10% currently applies to dividends paid by a PRC “resident enterprise” to a foreign enterprise investor, unless any such foreign investor’s jurisdiction of incorporation has a tax treaty with China that provides for preferential tax treatment. Pursuant to the Arrangement between Mainland China and the Hong Kong for the Avoidance of Double Taxation and Prevention of Fiscal Evasion with Respect to Taxes on Income, such withholding tax rate may be lowered to 5% if a Hong Kong resident enterprise owns no less than 25% of a PRC enterprise. However, the 5% withholding tax rate does not automatically apply and certain requirements must be satisfied, including without limitation that (a) the Hong Kong enterprise must be the beneficial owner of the relevant dividends; and (b) the Hong Kong enterprise must directly hold no less than 25% share ownership in the PRC enterprise during the 12 consecutive months preceding its receipt of the dividends.

Dividends payable to our foreign investors and gains on the sale of our ADSs and/or ordinary shares by our foreign investors may become subject to PRC tax.

Under the Enterprise Income Tax Law and its implementation regulations issued by the State Council, a 10% PRC withholding tax, subject to any reduction or exemption set forth in applicable tax treaties or under applicable tax arrangements between jurisdictions, is applicable to dividends payable to investors that are non-resident enterprises, which do not have an establishment or place of business in the PRC or which have such establishment or place of business but the dividends are not effectively connected with such establishment or place of business, to the extent such dividends are derived from sources within the PRC. Similarly, any gain realized on the transfer of ADSs and/or ordinary shares by such investors is also subject to PRC tax at a current rate of 10%, subject to any reduction or exemption set forth in applicable tax treaties or under applicable tax arrangements between jurisdictions, if such gain is regarded as income derived from sources within the PRC. If we are deemed a PRC resident enterprise, dividends paid on our ordinary shares and/or ADSs, and any gain realized from the transfer of our ordinary shares and/or ADSs, would be treated as income derived from sources within the PRC and would as a result be subject to PRC taxation. Furthermore, if we are deemed a PRC resident enterprise, dividends payable to individual investors who are non-PRC residents and any gain realized on the transfer of ADSs and/or ordinary shares by such investors may be subject to PRC tax at a current rate of 20%, subject to any reduction or exemption set forth in applicable tax treaties or under applicable tax arrangements between jurisdictions. If we or any of our subsidiaries established outside mainland China are considered a PRC resident enterprise, it is unclear whether holders of our ADSs and/or ordinary shares would be able to claim the benefit of income tax treaties or agreements entered into between mainland China and other countries or areas. If dividends payable to our non-PRC investors, or gains from the transfer of our ADSs and/or ordinary shares by such investors, are deemed as income derived

S-29

TABLE OF CONTENTS

from sources within the PRC and thus are subject to PRC tax, the value of your investment in our ADSs and/or ordinary shares may decline significantly.

We and our shareholders face uncertainties with respect to indirect transfers of equity interests in PRC resident enterprises or other assets attributed to a Chinese establishment of a non-Chinese company, or immovable properties located in China owned by non-Chinese companies.

On February 3, 2015, the STA issued the Bulletin on Issues of Enterprise Income Tax on Indirect Transfers of Assets by Non-PRC Resident Enterprises, or STA Bulletin 7, which replaced or supplemented previous rules under the Notice on Strengthening Administration of Enterprise Income Tax for Share Transfers by Non-PRC Resident Enterprises, or Circular 698, issued by the STA, on December 10, 2009. Pursuant to STA Bulletin 7, an “indirect transfer” of assets, including equity interests in a PRC resident enterprise, by non-PRC resident enterprises may be recharacterized and treated as a direct transfer of PRC taxable assets, if such arrangement does not have a reasonable commercial purpose and was established for the purpose of avoiding payment of PRC enterprise income tax. As a result, gains derived from such indirect transfer may be subject to PRC enterprise income tax. According to STA Bulletin 7, “PRC taxable assets” include assets attributed to an establishment in China, immovable properties located in China, and equity investments in PRC resident enterprises, in respect of which gains from their transfer by a direct holder, being a non-PRC resident enterprise, would be subject to PRC enterprise income taxes. When determining whether there is a “reasonable commercial purpose” of the transaction arrangement, features to be taken into consideration include: whether the main value of the equity interest of the relevant offshore enterprise derives from PRC taxable assets; whether the assets of the relevant offshore enterprise mainly consists of direct or indirect investment in China or if its income mainly derives from China; whether the offshore enterprise and its subsidiaries directly or indirectly holding PRC taxable assets have real commercial nature which is evidenced by their actual function and risk exposure; the duration of existence of the business model and organizational structure; the replicability of the transaction by direct transfer of PRC taxable assets; and the tax situation of such indirect transfer and applicable tax treaties or similar arrangements. In respect of an indirect offshore transfer of assets of a PRC establishment, the resulting gain is to be included with the enterprise income tax filing of the PRC establishment or place of business being transferred, and would consequently be subject to PRC enterprise income tax at a rate of 25%. Where the underlying transfer relates to the immovable properties located in China or to equity investments in a PRC resident enterprise, which is not related to a PRC establishment or place of business of a non-resident enterprise, a PRC enterprise income tax of 10% would apply, subject to available preferential tax treatment under applicable tax treaties or similar arrangements, and the party who is obligated to make the transfer payments has the withholding obligation. Where the payor fails to withhold any or sufficient tax, the transferor shall declare and pay such tax to the tax authority by itself within the statutory time limit. Late payment of applicable tax will subject the transferor to default interest. STA Bulletin 7 does not apply to transactions of sale of ordinary shares by investors through a public stock exchange where such ordinary shares were acquired from a transaction through a public stock exchange.

On October 17, 2017, the STA issued the Announcement on Issues Relating to Withholding at Source of Income Tax of Non-resident Enterprises, or STA Circular 37. STA Circular 37 supersedes Circular 698 in its entirety, and amends certain provisions in STA Bulletin 7, but does not touch upon other provisions of STA Bulletin 7, which remain in full force. STA Circular 37 purports to clarify certain issues in the implementation of the above regime, by providing, among others, the definitions of equity transfer income and tax basis, the foreign exchange rate to be used in the calculation of withholding amounts and the date of occurrence of the withholding obligation. Specifically, STA Circular 37 provides that where the transfer income subject to withholding at its source is derived by a non-PRC resident enterprise by way of instalments, the instalments may first be treated as recovery of costs of previous investments; upon recovery of all costs, the tax amount to be withheld shall then be computed and withheld.

There is uncertainty as to the application of STA Bulletin 7 and STA Circular 37. STA Bulletin 7 and STA Circular 37 may be determined by the tax authorities to be applicable to our historical or future offshore restructuring transactions or sale of our ordinary shares or ADSs or those of our offshore subsidiaries, with non-resident enterprises being the transferors. We may be subject to filing obligations or taxed as the transferor, or subject to withholding obligations as the transferee, in such transactions. For transfers of our ordinary shares or ADSs by investors that are non-PRC resident enterprises, our mainland China subsidiaries may be requested to assist with filings under STA Bulletin 7 and STA Circular 37. For example, in the past, we

S-30

TABLE OF CONTENTS

acquired EDC Holding Limited, or EDC Holding, by issuing shares of GDS Holdings, to its shareholders in exchange for all of the outstanding shares of EDC Holding that were not held by us then. In addition, certain of our direct and indirect shareholders transferred some or all of their equity interest in us through indirect transfers conducted by their respective overseas holding companies which held ordinary shares in us. As a result, the transferors and transferees in these transactions, including us may be subject to the tax filing and withholding or tax payment obligation, while our mainland China subsidiaries may be requested to assist in the filing. Furthermore, we, our non-resident enterprises and mainland China subsidiaries may be required to spend valuable resources to comply with STA Bulletin 7 and STA Circular 37 or to establish that we and our non-resident enterprises should not be taxed under STA Bulletin 7 and STA Circular 37, for our previous and future restructuring or disposal of shares of our offshore subsidiaries, which may have a material adverse effect on our financial condition and results of operations.

Restrictions on currency exchange may limit our ability to utilize our net revenue effectively.

Substantially all of our net revenue is denominated in Renminbi. The Renminbi is currently convertible under the “current account,” which includes dividends, trade and service-related foreign exchange transactions, but not under the “capital account,” which includes foreign direct investment and loans, including loans we may secure from our onshore subsidiaries, VIEs or their subsidiaries. Currently, certain of our mainland China subsidiaries, may purchase foreign currency for settlement of “current account transactions,” including payment of dividends to us, without the approval of SAFE by complying with certain procedural requirements. However, the relevant PRC governmental authorities may limit or eliminate our ability to purchase foreign currencies in the future for current account transactions. Foreign exchange transactions under the capital account remain subject to limitations and require approvals from, or registration with, SAFE and other relevant PRC governmental authorities. Since a significant amount of our future net revenue will be denominated in Renminbi, any existing and future restrictions on currency exchange may limit our ability to utilize net revenue generated in Renminbi to fund our business activities outside of the PRC or pay dividends in foreign currencies to our shareholders, including holders of our ADSs and/or ordinary shares, and may limit our ability to obtain foreign currency through debt or equity financing for our subsidiaries, VIEs or their subsidiaries.

The audit report incorporated by reference into this prospectus supplement is prepared by an auditor which the U.S. Public Company Accounting Oversight Board was unable to inspect and investigate completely before 2022 and, as such, our investors had been deprived of the benefits of such inspections in the past, and may be deprived of the benefits of such inspections in the future.

Our auditor, the independent registered public accounting firm that issues the audit report incorporated by reference into this prospectus supplement, as an auditor of companies that are traded publicly in the U.S. and a firm registered with the PCAOB, is required by the laws of the U.S. to undergo regular inspections by the PCAOB to assess its compliance with the laws of the U.S. and professional standards. According to Article 177 of the PRC Securities Law which became effective in March 2020, no overseas securities regulator is allowed to directly conduct investigation or evidence collection activities within the territory of the PRC. Accordingly, without the consent of the competent PRC securities regulators and relevant authorities, no organization or individual may provide the documents and materials relating to securities business activities to overseas parties. In 2021, PCAOB made determinations that the positions taken by PRC authorities prevented the PCAOB from inspecting and investigating firms headquartered in mainland China and Hong Kong completely. On August 26, 2022, the PCAOB signed a Statement of Protocol with the CSRC and the Ministry of Finance of the PRC, taking the first step toward opening access for the PCAOB to inspect and investigate completely registered public accounting firms headquartered in mainland China and Hong Kong including our auditor. According to its announcement, the PCAOB sent staff to conduct on-site inspections and investigations in Hong Kong from September to November 2022 and conducted inspection field work and investigative testimony in a manner consistent with the PCAOB’s methodology and approach to inspections and investigations in the U.S. and globally. The PCAOB inspections have identified numerous deficiencies in the audit firms in China, which are consistent with the types and number of findings the PCAOB has encountered in other first-time inspections around the world. If audit firms in China had been subject to such inspections in the past, such deficiencies may have been identified earlier and these audit firms, including our auditor, may have taken remedial measures to address any such deficiencies, and the historical inability of the PCAOB to inspect audit firms in China has deprived our investors of the benefits of such inspections. The inability of the

S-31

TABLE OF CONTENTS

PCAOB to conduct complete inspections of auditors in China before 2022 may have made it more difficult to evaluate the effectiveness of our auditor’s audit procedures or quality control procedures as compared to auditors outside of China that are subject to PCAOB inspections, which could cause investors or potential investors in our ADSs to lose confidence in the quality of our consolidated financial statements.

In addition, while the PCAOB announced in December 2022 that it secured complete access to inspect and investigate registered public accounting firms headquartered in China, we cannot assure you that the PCAOB will continue to have such access in the future. If the PCAOB is not able to inspect and investigate completely auditors in China for any reason, such as any change in the position of the governmental authorities in China in the future, our investors may be deprived of the benefits of such inspections again.

The market prices of our ADSs and/or other securities could be adversely affected as a result of anticipated negative impacts of the HFCA Act upon, as well as negative investor sentiment towards, China-based companies listed in the United States, regardless of our actual operating performance. If our ADSs were not listed on a national stock exchange in the U.S., the Hong Kong Stock Exchange will regard us as having a primary listing in Hong Kong and we will no longer enjoy certain exemptions or waivers from strict compliance with the requirements under the Hong Kong Listing Rules, the Companies (WUMP) Ordinance, the Takeovers Codes and the SFO, which could result in our incurring incremental compliance costs. Notwithstanding the foregoing, in the event that the Hong Kong Stock Exchange deemed us as having a dual primary listing in Hong Kong, we will be permitted to retain our existing weighted voting rights structure and our variable interest entity structure. See “— Risks Related to Our ADSs and Class A Ordinary Shares — We adopt different practices as to certain matters as compared with many other companies listed on the Hong Kong Stock Exchange.”

If the PCAOB determines that it is unable to inspect or investigate completely our auditor at any point in the future, our ADSs may be prohibited from trading in the United States under the HFCA Act, as amended, and any such trading prohibition on our ADSs or threat thereof may materially and adversely affect the price of our ADSs and value of your investment.

The HFCA Act was signed into law on December 18, 2020 and amended pursuant to the Consolidated Appropriations Act, 2023 on December 29, 2022. Under the HFCA Act and the rules issued by the SEC and the PCAOB thereunder, if we have retained a registered public accounting firm to issue an audit report where the registered public accounting firm has a branch or office that is located in a foreign jurisdiction and the PCAOB has determined that it is unable to inspect or investigate completely because of a position taken by an authority in the foreign jurisdiction, the SEC will identify us as a “covered issuer”, or SEC-identified issuer, shortly after we file with the SEC a report required under the Securities Exchange Act of 1934, or the Exchange Act (such as our annual report on Form 20-F) that includes an audit report issued by such accounting firm; and if we were to be identified as an SEC-identified issuer for two consecutive years, the SEC would prohibit our securities (including our shares or ADSs) from being traded on a national securities exchange or in the over-the-counter trading market in the United States.

In December 2021, the PCAOB made its determinations, or the 2021 determinations, pursuant to the HFCA Act that it was unable to inspect or investigate completely registered public accounting firms headquartered in mainland China or Hong Kong including our auditor. After we filed our annual report on Form 20-F for the fiscal year ended December 31, 2021 on April 28, 2022, the SEC conclusively identified us as an SEC-identified issuer on May 26, 2022. As such, we were required to satisfy additional disclosure requirement for SEC-identified issuers that are also foreign issuers in our annual report as of December 31, 2022 and for the year then ended. See “Item 16I. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections” in our 2024 Annual Report.

Following the Statement of Protocol signed between the PCAOB and the CSRC and the Ministry of Finance of the PRC in August 2022 and the on-site inspections and investigations conducted by the PCAOB staff in Hong Kong from September to November 2022, the PCAOB Board voted in December 2022 to vacate the previous 2021 determinations, and as a result, our auditor is no longer a registered public accounting firm that the PCAOB is unable to inspect or investigate completely as of the date of this prospectus supplement or at the time of issuance of the audit report incorporated herein by reference. As such, we were not identified as an SEC-identified issuer following the filing of our annual reports in 2023 and 2024 and we do not expect to be so identified following the filing of our annual report in 2025 either. However, the PCAOB may change its

S-32

TABLE OF CONTENTS

determinations under the HFCA Act at any point in the future. In particular, if the PCAOB finds its ability to completely inspect and investigate registered public accounting firms headquartered in mainland China or Hong Kong is obstructed by the PRC authorities in any way in the future, the PCAOB may act immediately to consider the need to issue new determinations consistent with the HFCA Act. We cannot assure you that the PCAOB will always have complete access to inspect and investigate our auditor, or that we will not be identified as an SEC-identified issuer again in the future.

If we are identified as an SEC-identified issuer again in the future, we cannot assure you that we will be able to change our auditor or take other remedial measures in a timely manner, and if we were to be identified as an SEC-identified issuer for two consecutive years, we would be delisted from the Nasdaq and our securities (including our shares and ADSs) will not be permitted for trading “over-the-counter” either. If our securities are prohibited from trading in the United States, or threatened with such a prohibition, the risk and uncertainty associated with delisting would have a negative impact on the price of our ADSs and ordinary shares. Also, such a prohibition or any threat thereof would significantly affect our ability to raise capital on terms acceptable to us, or at all, which would have a material adverse impact on our business, financial condition, and prospects. Moreover, the implementation of the HFCA Act and other efforts to increase the U.S. regulatory access to audit information could cause investor uncertainty as to China-based issuers’ ability to maintain their listings on the U.S. national securities exchanges and the market price of the securities of China-based issuers, including us, could be adversely affected.

If additional remedial measures are imposed on the “big four” PRC-based accounting firms, including our independent registered public accounting firm, in administrative proceedings brought by the SEC alleging such firms’ failure to meet specific criteria set by the SEC with respect to requests for the production of documents, we could be unable to timely file future financial statements in compliance with the requirements of the U.S. Exchange Act.

Starting in 2011 the Chinese affiliates of the “big four” accounting firms, including our independent registered public accounting firm, were affected by a conflict between U.S. and Chinese law. Specifically, for certain U.S. listed companies operating and audited in mainland China, the SEC and the PCAOB sought to obtain from the Chinese accounting firms access to their audit work papers and related documents. The firms were, however, advised and directed that under Chinese law they could not respond directly to the U.S. regulators on those requests, and that requests by foreign regulators for access to such papers in China had to be channeled through the CSRC.

In December 2012, this impasse led the SEC to commence administrative proceedings under Rule 102(e) of its Rules of Practice and also under the Sarbanes-Oxley Act against the Chinese affiliates of the “big four” accounting firms, including our independent registered public accounting firm. In January 2014, the administrative law judge reached an initial decision to impose penalties on the firms including a temporary suspension of their right to practice before the SEC. The accounting firms filed a petition for review of the initial decision. On February 6, 2015, before a review by the commissioners of the SEC had taken place, the firms reached a settlement with the SEC. Under the settlement, the SEC accepts that future requests by the SEC for the production of documents will normally be made to the CSRC. The firms will receive matching Section 106 requests and are required to abide by a detailed set of procedures with respect to such requests, which in substance require them to facilitate production via the CSRC. If they fail to meet the specified criteria, the SEC retains authority to impose a variety of additional remedial measures on the firms depending on the nature of the failure. Remedies for any future non-compliance could include, as appropriate, an automatic six-month bar on a single firm’s performance of certain audit work, commencement of a new proceeding against a firm, or in extreme cases the resumption of the current proceeding against all four firms. Under the terms of the settlement, the underlying proceeding against the four PRC-based accounting firms was deemed dismissed with prejudice four years after entry of the settlement. The four-year mark occurred on February 6, 2019. It is uncertain whether the SEC will further challenge the four PRC-based accounting firms’ compliance with U.S. laws in connection with U.S. regulatory requests for audit work papers or if the results of such challenge would result in the SEC imposing penalties such as suspensions. If additional remedial measures are imposed on the Chinese affiliates of the “big four” accounting firms, including our independent registered public accounting firm, we could be unable to timely file future financial statements in compliance with the requirements of the U.S. Exchange Act.

TABLE OF CONTENTS

In the event that the SEC restarts the administrative proceedings, depending upon the final outcome, listed companies in the United States with major PRC operations may find it difficult or impossible to retain auditors in respect of their operations in the PRC, which could result in financial statements being determined to not be in compliance with the requirements of the U.S. Exchange Act, including possible delisting. Moreover, any negative news about any such future proceedings against these audit firms may cause investor uncertainty regarding China-based, United States-listed companies and the market price of our ADSs and/or ordinary shares may be adversely affected.

The perception among investors that the Company is at heightened risk of delisting from Nasdaq could negatively affect the market price of our securities and trading volume of our ADSs. If a delisting were to occur, we would face material adverse consequences.

The perception among investors, due to current and proposed rules and regulations relating to the ability of the PCAOB to inspect our auditors, political tensions between the United States and China, and other matters, that the Company is at heightened risk of delisting from Nasdaq, could negatively affect the market price of our securities and trading volume of our ADSs. There have been recent media reports on deliberations within the U.S. government regarding limiting or restricting China-based companies from accessing U.S. capital markets, and delisting China-based companies from U.S. national securities exchanges. On April 9, 2025, amid the escalating trade war between the U.S. and China, the U.S. Secretary of the State, Scott Bessent, indicated the possibility of delisting U.S. — listed China — based issuers. If any further such deliberations were to materialize, the resulting legislation may have a material and adverse impact on the stock performance of China-based issuers listed in the United States such as us, and there can be no assurance that we will always be able to maintain the listing of our ADSs on a national stock exchange in the U.S., such as the NYSE or the Nasdaq Stock Market, or that you will always be allowed to trade our shares or ADSs. See “— The audit report incorporated by reference into this prospectus supplement is prepared by an auditor which the U.S. Public Company Accounting Oversight Board was unable to inspect and investigate completely before 2022 and, as such, our investors had been deprived of the benefits of such inspections in the past, and may be deprived of the benefits of such inspections in the future.” If our ADSs were not listed on a national stock exchange in the U.S., the Hong Kong Stock Exchange will regard us as having a primary listing in Hong Kong and we will no longer enjoy certain exemptions or waivers from strict compliance with the requirements under the Hong Kong Listing Rules, the Companies (WUMP) Ordinance, the Takeovers Codes and the SFO, which could result in our incurring incremental compliance costs. Notwithstanding the foregoing, in the event that the Hong Kong Stock Exchange deemed us as having a dual primary listing in Hong Kong, we will be permitted to retain our existing weighted voting rights structure and our variable interest entity structure. See “— Risks Related to Our ADSs and Class A Ordinary Shares — We adopt different practices as to certain matters as compared with many other companies listed on the Hong Kong Stock Exchange.”

Additionally, any actual delisting determination could seriously decrease or eliminate the value of an investment in our ADSs. We could face substantial material adverse consequences, including, but not limited to, among other things: limited availability for market quotations for our ADSs; reduced liquidity with respect to our shares; a reduced number of investors willing to hold or acquire our shares, which could negatively impact our ability to raise equity financing; an impaired ability to provide equity incentives to our employees; and limited news and analyst coverage. Additionally, many of our loan agreements include a covenant that we maintain our shares listed on at least one of the following stock exchanges before the maturity date: (i) Nasdaq; or (ii) The Singapore Exchange Securities Trading Limited; or (iii) the Hong Kong Stock Exchange; or (iv) any other stock exchange acceptable to the lender. The breach of such covenant could result in a default with respect to the related indebtedness. If a default occurs, the relevant lenders could elect to declare the indebtedness, together with accrued interest and other fees, to be due and payable immediately. This, in turn, could cause our other debt, to become due and payable as a result of cross-default or acceleration provisions contained in the agreements governing such other debt. In the event that some or all of our debt is accelerated and becomes immediately due and payable, we may not have the funds to repay, or the ability to refinance, such debt.

Risks Relating to This Offering

Sales of our Class A ordinary shares, ADSs, or other equity or equity-linked securities in the public market, or the perception that these sales could occur, could cause the trading price of our Class A ordinary shares and/or ADSs to decline significantly. Upon completion of this offering of the ADSs and the Concurrent Primary ADS Offering, we will have ordinary shares issued and outstanding, including Class A ordinary shares and 43,590,336 Class B ordinary shares. Excluding the Class A ordinary shares to be issued pursuant to the ADS Loan under the ADS Lending Agreement, our total ordinary shares outstanding will be . All ADSs sold in this offering will be freely transferable by persons other than our “affiliates” without restriction or additional registration under the Securities Act. Some ordinary shares and/or ADSs outstanding after this offering, the Concurrent Notes Offering and the Concurrent Primary ADSs Offering and held by certain of our officers, directors and principal shareholders will be available for sale, upon the expiration of the lock-up periods (if applicable to such holder), subject to volume and other restrictions as applicable under Rules 144 and 701 under the Securities Act. Any or all of these ordinary shares or ADSs may be released prior to the expiration of the applicable lock-up period at the discretion of the Borrowed ADS Underwriter, the initial purchaser or the underwriters, as applicable for the respective offering. See “Underwriting (Conflicts of Interest).” Our other outstanding ordinary shares and/or ADSs not subject to lock-up may be available for sale immediately after the date of this prospectus supplement. To the extent a substantial amount of such securities are sold into the market, the market price of our ADSs could decline significantly.

Certain major holders of our ordinary shares have the right to cause us to register under the Securities Act the sale of their shares, subject to the applicable lock-up periods. Registration of these shares under the Securities Act would result in ADSs representing these shares becoming freely tradable without restriction under the Securities Act immediately upon the effectiveness of the registration. Sales of these registered shares in the form of ADSs in the public market could cause the price of our ADSs to decline significantly.

In addition, the convertible senior notes in the concurrent offering and our existing convertible notes may also encourage short selling by market participants because the conversion of the convertible senior notes could depress our ADS price. The price of our ADSs could be affected by possible sales of our ADSs by investors who view the convertible senior notes as a more attractive means of equity participation in us and by hedging or arbitrage trading activity involving our ADSs.

The ADSs are equity and are subordinate to our existing and future indebtedness, the convertible preferred stock and any preferred stock we may issue in the future.

The ADSs are our equity interests and do not constitute indebtedness. As such, ADSs will rank junior to all indebtedness and other non-equity claims on us with respect to assets available to satisfy claims on us, including in a liquidation of us. Additionally, holders of our ADSs may be subject to prior dividend and liquidation rights of any holders of our preferred stock or depositary shares representing such preferred stock then outstanding.

Our ADSs will rank junior to our convertible preferred stock with respect to the payment of dividends and amounts payable in the event of our liquidation, dissolution or winding-up of our affairs. This means that, unless accumulated dividends have been paid on all our convertible preferred stock through the most recently completed dividend period, no dividends may be declared or paid on our ADSs and we will not be permitted to repurchase any of our ADSs, subject to limited exceptions. Likewise, in the event of our voluntary or involuntary liquidation, dissolution or winding-up of our affairs, no distribution of our assets may be made to holders of our ADSs until we have paid to holders of our preferred stock a liquidation preference equal to the greater of (i) the stated value per convertible preferred share, plus an amount equal to any dividends accumulated but unpaid thereon (whether or not declared), and (ii) the payment such holders would have received had such holders, immediately prior to such liquidation, converted their convertible preferred shares into Class A ordinary shares (at the then applicable conversion rate).

TABLE OF CONTENTS

Our board of directors is authorized to issue additional classes or series of preferred stock without any action on the part of the shareholders. The board of directors also has the power, without shareholder approval, to set the terms of any such classes or series of preferred stock that may be issued, including voting rights, dividend rights, and preferences over our ADSs with respect to dividends or upon our dissolution, winding-up and liquidation and other terms. If we issue preferred stock in the future that has a preference over our ADSs with respect to the payment of dividends or upon our liquidation, dissolution, or winding up, or if we issue preferred stock with voting rights that dilute the voting power of our ADSs, the rights of holders of our ADSs or the market price of our ADSs could be adversely affected.

You must rely on the judgment of our management as to the use of the net proceeds from the offering of Primary ADSs, and such use may not produce income or increase the price of our ADS.

We expect to use the net proceeds from the offering of Primary ADSs for general corporate purposes, working capital needs and the refinancing of our existing indebtedness, including reserving amounts for possible future negotiated repurchases of, or for redemption upon exercise of the investor put right, of our convertible bonds due 2029. Our management will have considerable discretion in the application of the net proceeds received by us. You will not have the opportunity, as part of your investment decision, to assess whether proceeds are being used appropriately. The net proceeds may be used for corporate purposes that do not improve our efforts to achieve or maintain profitability or increase the price of our ADS. The net proceeds from this offering may be placed in investments that do not produce income or that lose value.

Changes in the accounting guidelines relating to the Borrowed ADS could decrease our earnings per ADS and potentially the price of our ADS.

The ADS Borrower is hereby offering ADSs, which are being borrowed pursuant to the ADS Lending Agreement by the ADS Borrower, and its affiliate is acting as the underwriter in this offering. The ADS Borrower and its affiliates will receive all of the proceeds from the sale of the Borrowed ADSs. We will not receive any proceeds from the sale of the Borrowed ADSs pursuant to this prospectus supplement, but we will receive a nominal lending fee of US$0.0004 per Borrowed ADS for the use of those ADSs.

Subject to certain terms of the ADS Lending Agreement, the Borrowed ADSs generally must be returned to us as soon as practicable after the termination of the ADS Lending Facility and in any event no later than the twenty-fifth trading day following the day we notify the ADS Borrower of our intention to terminate the ADS Lending Agreement at any time after the date on which the entire principal amount of the convertible senior notes being offered concurrently cease to be outstanding, or earlier in certain circumstances. Based on the terms of the ADS Lending Agreement, we believe that, under U.S. GAAP (as in effect on the date of this prospectus supplement), the Borrowed ADSs will not be considered outstanding for the purpose of computing and reporting our net income (loss) per ADS. If these accounting guidelines were to change in the future, we might be required to treat the Borrowed ADSs as outstanding for purposes of computing earnings per ADS, in which case our net income per ADS would be reduced and our ADS price could decrease, possibly significantly. The Class A ordinary shares underlying the Borrowed ADSs will be considered issued and outstanding as fully paid shares for Cayman Islands company law purposes, including voting rights and dividend rights.

The effect of the borrowing of our ADSs pursuant to the ADS Lending Agreement and the issuance of our ADSs in this offering may adversely affect the market price of our ADSs.

The increase in the number of outstanding ADSs and the sale of the Borrowed ADSs could have a negative effect on the market price of our ADSs. The existence of the ADS Lending Agreement, the short sales of our ADSs and related derivative transactions effected in connection with the sale of our convertible senior notes, or any unwind of such short sales or derivatives transactions, each as described under “— Description of the Delta Placement of Borrowed ADSs and Concurrent Offering of Convertible Senior Notes,” could cause the market price of our ADSs to be lower over the term of the ADS Lending Agreement than it would have been had we not entered into that agreement. The market price of our ADSs could be further negatively affected by these or other short sales of our ADSs, including other sales by the purchasers of the convertible senior notes hedging their investment therein. The effect, if any, of these activities on the market price of our ADSs will

S-36

TABLE OF CONTENTS

depend on a variety of factors, including market conditions, and cannot be ascertained at this time. Any of these activities could, however, cause or avoid an increase or a decrease in the market price of our ADSs.

The number of Borrowed ADSs to be sold hereunder will depend on what portion of investors in the Concurrent Notes Offering desire to hedge their investment in the Notes through privately negotiated derivatives transactions with the ADS Borrower or its affiliates, and will be determined at the time of pricing of the Delta Placement of Borrowed ADSs and is expected to be no greater than commercially reasonable initial short positions of such convertible arbitrage investors. It is possible, however, that investors in the Notes in the Concurrent Notes Offering may short sell additional shares of our Class A ordinary shares shortly after the pricing of this offering. Such additional sales could have the effect of causing the market price of our shares of Class A ordinary shares to be lower than it would have been absent such selling.

The ADS Lending Agreement is intended to facilitate privately negotiated derivative transactions relating to the ADSs, including cash-settled swaps between the ADS Borrower and investors in the convertible senior notes, by which investors in our convertible senior notes in the Concurrent Notes Offering will hedge their market risk with respect to the convertible senior notes, concurrently with, or shortly after, the pricing of the convertible senior notes. After placement of the convertible senior notes and the Borrowed ADSs, neither we nor the ADS Borrower will control how such holders may use such hedging transactions. In addition, such holders may enter into other transactions in connection with such hedging transactions, including the purchase or sale of ADSs.

Pursuant to the ADS Lending Agreement, the ADS Borrower has re-delivery obligations in respect of any Borrowed ADSs subject to the Loan Transaction, as well as for cash and non-cash distributions in respect of the notional number of the then-outstanding Borrowed ADSs (whether or not such ADS Borrower holds such ADSs). Such re-delivery may be in the form of ADSs that the ADS Borrower may need to procure by purchasing in the open market.

As a result, the existence of the ADS Lending Agreement, such hedging transactions, and any related market activity could cause the market price of the ADSs to be lower over the term of the ADS Lending Agreement than it would have otherwise been had we not entered into the ADS Lending Agreement.

Adjustments by convertible senior note investors of their hedging positions in our ADSs and the expectation thereof may have a negative effect on the market price of our ADSs.

Selling the Borrowed ADSs in this offering will allow the Borrowed ADS Underwriter or its affiliates to facilitate privately negotiated derivative transactions, by which certain investors in our convertible senior notes, who employ a convertible arbitrage strategy, will hedge their market risk with respect to the convertible senior notes. The number of Borrowed ADSs offered hereby may be more or less than the number of ADSs that will be needed in such hedging transactions at any point in time. Neither we nor the ADS Borrower will control any transactions that investors in our convertible senior notes may enter into at any time referencing any of our securities, including purchases and sales of our Class A ordinary shares or equivalent derivative transactions. Any buying or selling of our ADSs or entering into equivalent derivative transactions by investors in the convertible senior notes to adjust their hedging positions or otherwise in the future may affect the market price of our ADSs.

We may not have the ability to raise the funds necessary to (i) repurchase the convertible senior notes and other convertible senior notes on specified dates, (ii) repurchase the convertible senior notes offered in the Concurrent Notes Offering and/or the existing convertible senior notes upon the occurrence of a fundamental change, or the notes offered in the Concurrent Notes Offering and/or the existing convertible senior notes upon a redemption, or (iii) settle conversions of the notes offered in the Concurrent Notes Offering in cash (if cash settlement or combination settlement applies) or to repay the principal of the convertible senior notes offered in the Concurrent Notes Offering and the existing convertible senior notes at maturity, and our future debt may contain limitations on our ability to pay cash upon conversion or upon required repurchase or redemption of the convertible senior notes.

Holders of the convertible senior notes will have the right to require us to repurchase their convertible senior notes on June 1, 2029, or if a fundamental change occurs, for cash, all or a portion of their convertible senior notes. We may not have sufficient funds to pay the interest or repurchase price. If we fail to pay interest on the

S-37

TABLE OF CONTENTS

convertible senior notes or repurchase the convertible senior notes, we will be in default under the indenture governing the convertible senior notes, which in turn may constitute a default under existing and future agreements governing our indebtedness. In addition, if the initial purchasers exercises their option to purchase additional convertible senior notes in full, or if we issue other debt securities in the future, our debt service obligations will increase. The existing convertible senior notes contain similar protections concerning the holders’ right to require us to repurchase the existing convertible senior notes upon the occurrence of a fundamental change (as defined in the terms of such existing convertible senior notes) as well as similar provisions regarding our ability to redeem the existing convertible senior notes in case of certain changes in tax law, upon a cleanup redemption by us or upon an optional redemption by us.

In addition, upon conversion of the convertible senior notes, unless we elect to deliver solely ADSs (or Class A ordinary shares if such holder elects to receive Class A ordinary shares in lieu of any ADSs deliverable upon conversion) to settle such conversion (other than paying cash in lieu of delivering any fractional ADS), we will be required to make cash payments in respect of the notes being converted.

However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of the notes (or the existing convertible senior notes) surrendered therefor or redeem the convertible senior notes (or the existing convertible senior notes) or the convertible senior notes (or the existing convertible senior notes) being converted. In addition, our ability to repurchase the convertible senior notes (or the existing convertible senior notes), redeem the convertible senior notes (or the existing convertible senior notes) or pay cash upon conversions of the convertible senior notes (or the existing convertible senior notes) may be limited by law, by regulatory authority or by agreements governing our and/or our subsidiaries’ current or future indebtedness. Our failure to repurchase the notes or pay the redemption price or repay the principal at a time when the repurchase or such payment is required by the indenture governing the convertible senior notes or to pay any cash payable on future conversions of the convertible senior notes would constitute a default under the indenture governing the convertible senior notes. There would be similar consequences under the indentures governing the existing convertible senior notes in case of a failure to repurchase such existing convertible senior notes or pay the redemption price or repay the principal thereunder. A default under the indenture or the fundamental change itself could also lead to a default under any indenture or agreement governing our indebtedness or any future indebtedness. If the repayment of the existing convertible senior notes or any indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the existing convertible senior notes or other indebtedness and repurchase the notes or make cash payments upon conversions thereof.

Provisions of the convertible senior notes being offered concurrently could also discourage an acquisition of us by a third party.

Certain provisions of the convertible senior notes could make it more difficult or more expensive for a third party to acquire us, or may even prevent a third party from acquiring us. For example, upon the occurrence of certain transactions constituting a fundamental change, holders of the convertible senior notes will have the right, at their option, to require us to repurchase all of their convertible senior notes or any portion of the principal amount of the convertible senior notes in integral multiples of US$1,000. We may also be required to increase the conversion rate for conversions in connection with certain fundamental changes. By discouraging an acquisition of us by a third party, these provisions could have the effect of depriving the holders of our Class A ordinary shares and holders of our ADSs of an opportunity to sell their Class A ordinary shares and ADSs, as applicable, at a premium over prevailing market prices.

We are subject to counterparty risk with respect to the ADS Lending Agreement.

We are subject to the risk that the ADS Borrower may default under the ADS Lending Agreement. Our exposure to the ADS Borrower under the ADS Lending Agreement will not be secured by any collateral. In the past, economic conditions have resulted in the actual or perceived failure or financial difficulties of a number of financial institutions, including the bankruptcy filing by Lehman Brothers Holdings Inc. and various of its affiliates. If the ADS Borrower becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under our transactions with the ADS Borrower. Our exposure to the ADS Borrower under the ADS Lending Agreement will depend on many factors. Generally, our exposure will be correlated to the market price of our ADSs and the number

S-38

TABLE OF CONTENTS

of Borrowed ADSs outstanding at the time of any default by the ADS Borrower. We can provide no assurances as to the financial stability or viability of the ADS Borrower.

You may be subject to limitations on transfer of your ADSs.

Your ADSs are transferable on the books of the Depositary. However, the Depositary may close its transfer books at any time or from time to time when it deems expedient in connection with the performance of its duties. In addition, the Depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

We may become a passive foreign investment company, which could result in adverse U.S. federal income tax consequences to U.S. investors.

Based on the past and projected composition of our income and assets and the valuation of our assets, we do not believe we were a passive foreign investment company, or PFIC, for our most recent taxable year and we do not expect to be a PFIC for our current taxable year or in the foreseeable future, although there can be no assurance in this regard. The determination of whether or not we are a PFIC is made on an annual basis and will depend on the composition of our income and assets from time to time. Specifically, for any taxable year, we will be classified as a PFIC for U.S. federal income tax purposes if either (i) 75% or more of our gross income in that taxable year is passive income or (ii) the average percentage of our assets (which includes cash) by value in that taxable year which produce, or are held for the production of, passive income is at least 50%. The calculation of the value of our assets will be based, in part, on the quarterly market value of our ADSs, which is subject to change. See “Taxation — U.S. Federal Income Tax Considerations — Passive Foreign Investment Company Considerations.”

In addition, there is uncertainty as to the treatment of our corporate structure and ownership of the VIEs for U.S. federal income tax purposes. For U.S. federal income tax purposes, we consider ourselves to own the stock of the VIEs. If it is determined, contrary to our view, that we do not own the stock of the VIEs for U.S. federal income tax purposes (for instance, because the relevant PRC authorities do not respect these arrangements), we may be treated as a PFIC.

If you are a U.S. holder, as defined under “Taxation — U.S. Federal Income Tax Considerations,” and we are a PFIC for any taxable year during which you hold our ADSs or Class A ordinary shares, our PFIC status could result in adverse U.S. federal income tax consequences to you. For example, if we are or become a PFIC, you may become subject to increased tax liabilities under U.S. federal income tax laws and regulations and may become subject to burdensome reporting requirements. In some cases, shareholders of a PFIC may make one of certain elections that would ameliorate some of the adverse tax consequences of the PFIC rules. See “Taxation — U.S. Federal Income Tax Considerations — Passive Foreign Investment Company Considerations” for further details. You are urged to consult your own tax advisors concerning the U.S. federal income tax consequences of the application of the PFIC rules.

There can be no assurance that we will not be a PFIC for the current or any future taxable year.

TABLE OF CONTENTS

DIVIDEND POLICY

Since our inception, except for the US$50.8 million preference dividend paid to our preferred shareholders upon completion of our initial public offering, of which US$11.4 million was paid in cash and US$39.4 million was paid in the form of 31,490,164 Class A ordinary shares based on the initial public offering price of US$10.00 per ADS and dividends on our preferred shares issued on March 19, 2019, we have not declared or paid any dividends on our shares. We do not have any present plan to pay any dividends on our Class A ordinary shares or ADSs in the foreseeable future. We intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business.

The holder of our convertible preferred shares, i.e., an affiliate of Ping An Overseas Holdings, is entitled to receive cumulative preferred dividends which began to accrue and accumulate from the date the convertible preferred shares were issued, regardless of whether any funds of our company are legally available for the payment of such dividends. The cumulative preferred dividends generally accrue (i) during the first eight years from the issuance date, at a minimum rate of 5% per annum of a specified value for each convertible preferred share, payable quarterly in arrears, in cash or in kind in the form of additional convertible preferred shares, at our option, and (ii) as of the eighth anniversary of the issuance date, at a minimum rate of 7% per annum of a specified value for each convertible share, payable quarterly in arrears, in cash only, which rate shall be further increased by 50 basis points per quarter thereafter for so long as any convertible preferred shares remain outstanding. If the aggregate amounts of dividend on its ordinary shares are higher than the cumulative preferred share dividends over the four consecutive quarters, the holders of preferred shares have the right to receive the dividend in an amount equal to the dividend paid to the holders of ordinary shares (treating each holder of convertible preferred shares as being the holder of the number of Class A ordinary shares into which such holder’s convertible preferred shares would be converted if such shares were converted at the end of each period).

Any future determination to pay dividends will be made at the discretion of our board of directors and may be based on a number of factors, including our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant. If we pay any dividends, we will pay our ADS holders to the same extent as holders of our Class A ordinary shares, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder. Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.

We are an exempted company incorporated in the Cayman Islands. In order for us to distribute any dividends to our shareholders and ADS holders, we may rely on dividends distributed by our mainland China subsidiaries. Certain payments from our mainland China subsidiaries to us may be subject to PRC withholding tax. In addition, regulations in the PRC currently permit payment of dividends of a PRC company only out of accumulated distributable after-tax profits as determined in accordance with its articles of association and the accounting standards and regulations in mainland China. Each of our mainland China subsidiaries is required to set aside at least 10% of its after-tax profit based on PRC accounting standards every year to a statutory common reserve fund until the aggregate amount of such reserve fund reaches 50% of the registered capital of such subsidiary. Such statutory reserves are not distributable as loans, advances or cash dividends.

TABLE OF CONTENTS

DESCRIPTION OF THE DELTA PLACEMENT OF BORROWED ADSs AND CONCURRENT OFFERING CONVERTIBLE SENIOR NOTES

Concurrently with the Delta Placement of Borrowed ADSs (as defined below), we are offering US$450,000,000 aggregate principal amount of convertible senior notes, plus up to US$50,000,000 aggregate principal amount of our convertible senior notes if the initial purchasers exercise their option to purchase additional convertible senior notes in full, in reliance on the exemption from registration provided by Rule 144A under the Securities Act (the “Concurrent Notes Offering”).

The ADS Borrower or its affiliates will use the short positions resulting from the Delta Placement of the Borrowed ADSs to facilitate privately negotiated derivative transactions, by which certain investors in our convertible senior notes, who employ a convertible arbitrage strategy, will hedge their market risk with respect to the convertible senior notes. These derivative transactions are expected to be on market-standard terms for such type of transactions. During the term of such transactions, such investors may use their synthetic short positions established thereunder at their sole discretion.

The number of Borrowed ADSs to be sold hereunder will depend on what portion of investors in the Concurrent Notes Offering desire to hedge their investment in the Notes through privately negotiated derivatives transactions with the ADS Borrower or its affiliates, and will be determined at the time of pricing of the Delta Placement of Borrowed ADSs and is expected to be no greater than commercially reasonable initial short positions of such arbitrage investors. It is possible, however, that investors in the Notes in the Concurrent Notes Offering may short sell additional shares of our Class A ordinary shares shortly after the pricing of this offering. Such additional sales could have the effect of causing the market price of our shares of Class A ordinary shares to be lower than it would have been absent such selling.

The underwriters will initially offer the Borrowed ADSs to the public at US$ per ADS, which is the same price as the price to the public per ADS in the Concurrent Primary ADSs Offering (each as defined below), and may subsequently offer such Borrowed ADSs for sale in one or more transactions on the Nasdaq Global Market, in the over the counter market, through negotiated transactions or otherwise, at market prices prevailing at the time of sale, at prices related to prevailing market prices at the time of sale or at negotiated prices. See “Underwriting (Conflicts of Interest).” We do not expect to lend any additional ADSs to the ADS Borrower or any other party to facilitate any short positions that may be desired by any initial or subsequent investors in the convertible senior notes after this offering, and will not lend any additional ADSs following any exercise by the initial purchasers in the concurrent convertible notes offering described below of their option to purchase additional convertible senior notes. There can be no assurance that the ADS Borrower will continue to facilitate any privately negotiated derivative transactions by which any convertible arbitrage investors in our convertible senior notes may be hedging their exposure to the market risk of our ADSs and/or Class A ordinary shares during the term of such convertible senior notes. There is no intent that the Delta Placement of Borrowed ADSs will create any inventory of our ADSs and/or Class A ordinary shares with the ADS Borrower or its affiliates that could be made available for borrowing to any investor in our convertible senior notes during the term thereof.

Subject to the terms of the ADS Lending Agreement, the ADSs borrowed pursuant to the ADS Lending Agreement must generally be returned to us as soon as practicable after the termination of the ADS Lending Facility and in any event no later than the twenty-fifth trading day following the earliest of:

S-43

TABLE OF CONTENTS

•

the date on which we have notified the ADS Borrower in writing of our intention to terminate the ADS Lending Agreement at any time after the date on which the entire principal amount of the convertible senior notes ceases to be outstanding, whether as a result of conversion, redemption, repurchase, cancellation or otherwise; and

•

the date on which the ADS Lending Agreement terminates in accordance with its terms (including at the election of the ADS Borrower or us upon any event described below).

The ADS Borrower may not re-borrow any ADSs that it has returned to us under the ADS Lending Agreement.

The ADS Loan under the ADS Lending Agreement will terminate, and the Delta Placement of Borrowed ADSs will terminate, and any Borrowed ADSs must be returned to us if the Concurrent Notes Offering is not consummated. In addition, the ADS Borrower may terminate all or any portion of the ADS Loan under the ADS Lending Agreement at any time or upon our default under the ADS Lending Agreement, including certain breaches by us of our representations and warranties, covenants or agreements under the ADS Lending Agreement, or the bankruptcy of us or upon the occurrence of certain event described in the ADS Lending Agreement. We may terminate the ADS Loan with the ADS Borrower upon a default of the ADS Borrower under the ADS Lending Agreement, including certain breaches by the ADS Borrower of its representations and warranties, covenants or agreements under the ADS Lending Agreement, or the bankruptcy of the ADS Borrower.

If the ADS Borrower is legally prevented from returning the Borrowed ADSs to us or if it is impracticable for the ADS Borrower to return the Borrowed ADSs to us or, in certain other circumstances, the ADS Borrower may elect to either pay us the value of the Borrowed ADSs in cash instead of returning the Borrowed ADSs or provide collateral to us with equivalent value.

The ADS Borrower or its affiliates will receive all of the proceeds from the sale of the Borrowed ADSs borrowed pursuant to the ADS Lending Agreement and we will not receive any proceeds from the sale of the Borrowed ADSs, but the ADS Borrower will pay us a nominal lending fee of US$0.0004 per each Borrowed ADS.

The Class A ordinary shares underlying the Borrowed ADSs that we will issue to the ADS Borrower will be issued and outstanding as fully paid shares for company law purposes. The ADS depositary will be the holder of the Class A ordinary shares underlying the Borrowed ADSs. The holders of the Borrowed ADSs will have all of the rights of a holder of our outstanding ADSs, including the right, through the ADS depositary, to vote on all matters on which our ADS holders have a right to vote (except the ADS Borrower and its affiliates have agreed not to vote the Borrowed ADSs held by them) and the right, through the ADS depositary, to receive any dividends or other distributions made to ADS holders in respect of any dividend or other distribution that we may pay or make on our outstanding Class A ordinary shares. However, under the ADS Lending Agreement and on the terms set forth therein, the ADS Borrower has agreed:

•

to pay us an amount equal to any cash dividends or distributions (in liquidation or otherwise) that are paid on the Borrowed ADSs (net of any fees, costs or tax withholdings and deductions); and

•

to pay or deliver to us any other dividend or distribution on the Borrowed ADSs (other than a dividend or distribution of ADSs) (net of any fees, costs or tax withholdings and deductions), or, in certain circumstances, an amount equal to the value thereof (net of any fees, costs or tax withholdings and deductions) or, subject to the terms of the ADS Lending Agreement, the increased number of the Borrowed ADSs reflecting the economic impact of such distribution..

The existence of the ADS Loan and the sale of the Borrowed ADSs under this prospectus supplement and the accompanying prospectus could have the effect of causing the market price of our ADSs and Class A ordinary shares to be lower over the term of the ADS Lending Agreement than it would have been had we not entered into the ADS Lending Agreement. In addition, any purchases of ADSs and/or Class A ordinary shares in connection with the termination of any portion of the ADS Lending Agreement or otherwise may have the effect of increasing, or preventing a decline in, the market price of our ADSs and Class A ordinary shares during or following the loan unwind period.

TABLE OF CONTENTS

maintain the orderly conduct of the meeting or allow the business of the meeting to be properly and effectively dealt with, while affording all shareholders a reasonable opportunity to express their views.

Pursuant to our Memorandum and Articles of Association the following matters are subject to ordinary resolution of the shareholders, with Class A ordinary shares and Class B ordinary shares each being entitled to one vote per share: (i) the election of two independent directors nominated by our nominating and corporate governance committee; (ii) any allotment or issuance of any of our shares or securities (in any 12-month period, whether in a single transaction or a series of transactions) equal to 10% or more of our share capital, or 10% or more of our voting power, prior to such allotment or issuance (without regard to any exemption from shareholder approval available under the Nasdaq Stock Market Rules); and (iii) any disposition of all, or 10% or more, of our undertakings or assets, as defined in our Memorandum and Articles of Association.

Subject to the abovementioned matters at general meetings of shareholders with respect to which Class B ordinary shares are entitled to 20 votes per share, an ordinary resolution to be passed by the shareholders requires the affirmative vote of a simple majority of votes attached to the ordinary shares cast in a general meeting, while a special resolution requires the affirmative vote of no less than 75% of votes attached to the ordinary shares cast in a general meeting. A special resolution is required for important matters such as a change of name or making changes to our Memorandum and Articles of Association.

Where any shareholder is, under the Hong Kong Listing Rules, required to abstain from voting on any particular resolution or restricted to voting only for or only against any particular resolution, any votes cast by or on behalf of such shareholder in contravention of such requirement or restriction shall not be counted.

Conversion. Class B ordinary shares are convertible into Class A ordinary shares. All Class B ordinary shares are subject to automatic conversion into Class A ordinary shares on the same business day as the first to occur of the following: (i) Mr. William Wei Huang ceasing to have beneficial ownership (as such term is interpreted pursuant to applicable U.S. securities laws and rules, regulations and forms promulgated thereunder by the SEC), in aggregate, of not less than two point seventy-five per cent (2.75%) of our issued and outstanding share capital on an as-converted basis, subject to certain exclusions; (ii) the Foreign Investment Law in the form implemented does not require that our VIE entities as it relates to VIE entities be owned or controlled by PRC nationals or entities; (iii) the PRC law no longer requires the conduct of the businesses carried out, or contemplated to be carried out, by us in the PRC, be owned or controlled by PRC nationals or entities; (iv) the promulgation of the Foreign Investment Law as it relates to VIE entities is abandoned by the relevant authorities in the PRC; or (v) the relevant authorities in the PRC approve our VIE structure without the need for our VIE entities to be controlled by PRC nationals or entities; provided, however, that the Class B ordinary shares shall not be automatically converted upon ceasing to constitute two point seventy-five per cent (2.75%) of our issued and outstanding share capital on an as-converted basis (subject to certain exclusions) if 75% of the board of directors resolve that such automatic conversion shall, in their opinion, result in our failing to comply with any applicable foreign ownership restrictions under PRC law. Class B shareholders may elect to convert any or all of their Class B ordinary shares into Class A ordinary shares. Each Class B ordinary share is generally convertible into one Class A ordinary share, or at a conversion rate of 1:1. However, if and when the nominal amount of one Class A ordinary share changes by reason of consolidation or sub-division, the applicable conversion rate of Class B ordinary shares into Class A ordinary shares shall equal the quotient of the revised nominal amount, divided by the former nominal amount, of one Class A ordinary share.

Transfer of Ordinary Shares.

Subject to the restrictions contained in our Articles of Association, as applicable, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in the usual or common form or any other form approved by our board of directors. Class B ordinary shares may not be assigned or transferred in whole or in part by a holder or such holder’s affiliate. Class B ordinary shares must be converted into Class A ordinary shares prior to any such assignment or transfer.

Our board of directors may, in its absolute discretion, decline to register any transfer of any ordinary share in the circumstances set out in our Memorandum and Articles of Association. Our board of directors may also decline to register any transfer of any ordinary share unless:

•

the instrument of transfer is lodged with us, accompanied by the certificate for the ordinary shares to which it relates and such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer;

S-47

TABLE OF CONTENTS

•

the instrument of transfer is in respect of only one class of ordinary shares;

•

the instrument of transfer is properly stamped, if required;

•

the ordinary shares transferred are fully paid and free of any lien in favor of us;

•

any fee related to the transfer has been paid to us; and

•

the transfer is not to more than four joint holders.

If our directors refuse to register a transfer they shall, within three months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal.

Liquidation. On a return of capital on winding up or otherwise (other than on conversion, redemption or purchase of ordinary shares), assets available for distribution among the holders of ordinary shares shall be distributed among the holders of the ordinary shares on a pro rata basis. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that the losses are borne by our shareholders proportionately.

Calls on Ordinary Shares and Forfeiture of Ordinary Shares. Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their ordinary shares. The ordinary shares that have been called upon and remain unpaid are subject to forfeiture.

Redemption of Ordinary Shares. Subject to the provisions of the Companies Act and other applicable law, we may issue shares on terms that are subject to redemption, at our option or at the option of the holders, on such terms and in such manner, including out of capital, as may be determined by the board of directors.

Variations of Rights of Shares

If at any time, our share capital is divided into different classes of shares, all or any of the special rights attached to any class of shares may, subject to the provisions of the Companies Act, be varied with the sanction of a special resolution passed at a general meeting of the holders of the shares of that class. Consequently, the rights of any class of shares cannot be detrimentally altered without a majority of two-thirds of the vote of all of the shares in that class. The rights conferred upon the holders of the shares of any class issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu with such existing class of shares

General Meetings of Shareholders

Shareholders’ meetings may be convened by a majority of our board of directors or our chairman. Advance notice of at least 21 calendar days is required for the convening of our annual general shareholders’ meeting, and advance notice of at least 14 calendar days is required for the convening of any extraordinary general meeting of our shareholders. A quorum required for a meeting of shareholders consists of at least two shareholders present or by proxy or by duly authorized representative, representing not less than one-third in nominal value of the total issued voting shares in our company, save that for any general meeting requisitioned according to Article 58(2)(iv), two shareholders entitled to vote and present in person or by proxy or (in the case of a shareholder being a corporation) by its duly authorized representative representing not less than 10% of the aggregate voting power in the Company throughout the meeting shall form a quorum.

Cayman Islands law provides shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with any right to put any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. Our Memorandum and Articles of Association allow our Class A shareholders (excluding STT Garnet and its controlled affiliates) holding shares representing in aggregate not less than one-third of the issued and outstanding Class A ordinary shares of our company (calculated excluding Class A ordinary shares beneficially owned by STT Garnet or its controlled affiliates), or any one or more shareholders holding at the date of deposit of the requisition not less than 10% of the voting rights, on a one vote per share basis, in the share capital of the Company, to requisition an extraordinary general meeting of our shareholders, in which case our directors are obliged to call such meeting and to put the resolutions so requisitioned to a vote at such meeting; however, our Memorandum and Articles of Association

S-48

TABLE OF CONTENTS

do not provide our shareholders with any right to put any proposals before annual general meetings or extraordinary general meetings not requisitioned by such shareholders. When STT Garnet no longer has any director appointment right as described herein, STT Garnet will be eligible for the same right to requisition a shareholder meeting described above on the same terms as other Class A ordinary shareholders, where the one-third of the Class A ordinary shares will then be calculated based upon all Class A ordinary shares issued and outstanding. STT Garnet and the Class B shareholders also have the right to requisition a general meeting insofar as is necessary to exercise and protect their respective nomination and appointment rights.

Inspection of Books and Records

Holders of our ordinary shares have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records. However, our Memorandum and Articles of Association provide our shareholders with the right to inspect our list of shareholders and to receive annual audited financial statements. See “Where You Can Find More Information About Us.”

Anti-Takeover Provisions in the Memorandum and Articles of Association.

Some provisions of our Articles of Association may discourage, delay or prevent a change in control of our company or management that shareholders may consider favorable, including provisions that authorize our board of directors to issue preferred shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preferred shares without any further vote or action by our shareholders.

However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our Memorandum and Articles of Association, as amended and restated from time to time, for what they believe in good faith to be in the best interests of our company.

Changes in Capital

We may from time to time by ordinary resolution:

•

increase the share capital by such sum, to be divided into shares of such classes and amount, as the resolution shall prescribe;

•

consolidate and divide all or any of our share capital into shares of a larger amount than our existing shares;

•

sub-divide our existing shares, or any of them into shares of a smaller amount; or

•

cancel any shares which, at the date of the passing of the resolution, have not been taken or agreed to be taken by any person and diminish the amount of our share capital by the amount of the shares so cancelled.

We may by special resolution reduce our share capital or any capital redemption reserve in any manner permitted by law.

Certain Enumerated Rights under Our Articles of Association

Appointment Rights

Our Articles of Association provide that for so long as STT Garnet beneficially owns: not less than 25% of our issued and outstanding share capital, they may appoint three directors to our board of directors, including our vice-chairman; less than 25%, but not less than 15%, of our issued and outstanding share capital, they may appoint two directors to our board of directors, including our vice-chairman; and less than 15%, but not less than 8%, of our issued and outstanding share capital, they may appoint one director to our board of directors, including our vice-chairman, none of which appointments will be subject to a vote by our shareholders. Our Articles of Association also provide that for so long as STT Garnet has the right to appoint one or more directors to our board of directors, any change in the total number of directors on our board shall require the approval of the director or directors appointed by STT Garnet. The above rights of STT Garnet may not be amended without the approval of STT Garnet.

S-49

TABLE OF CONTENTS

Our Articles of Association further provide that for so long as there are Class B ordinary shares outstanding, if any of the directors nominated by or subject to election by Class B shareholders at 20 votes per share (i) is not elected or (ii) ceases to be a director, then the Class B shareholders may appoint an interim replacement for each such director. As of and after such time as there cease to be any Class B ordinary shares outstanding, and for so long as Mr. William Wei Huang continues to have beneficial ownership in not less than 2% of our then issued share capital, subject to certain exclusions, Mr. William Wei Huang may appoint one director (which is intended to be Mr. William Wei Huang) to our board of directors. Such appointments will not be subject to a vote by our shareholders. Any person so appointed shall hold office until the next general meeting of our shareholders and be subject to re-nomination and re-election at such meeting.

Nomination Rights

Our Articles of Association also provide that for so long as Mr. William Wei Huang continues to have beneficial ownership (as such term is interpreted pursuant to applicable U.S. securities laws and rules, regulations and forms promulgated thereunder by the SEC), in aggregate, of not less than two point seventy-five per cent (2.75%) of our issued and outstanding share capital on an as-converted basis, subject to certain exclusions, the Class B shareholders shall have the right to nominate five of our directors, all of whom will be subject to a vote at general meetings of our shareholders and with respect to whom Class B ordinary shares will be entitled to 20 votes per share. If any of the directors nominated by or subject to election by the Class B shareholders at 20 votes per share (i) is not elected or (ii) ceases to be a director, then Mr. Huang may appoint another person to serve in the stead of such director. Any person so appointed shall hold office until the next general meeting of our shareholders and be subject to re-nomination and re-election at such meeting.

Exempted Company

We are an exempted company with limited liability under the Companies Act of the Cayman Islands. The Companies Act in the Cayman Islands distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except for the exemptions and privileges listed below:

•

an exempted company does not have to file an annual return of its shareholders with the Registrar of Companies;

•

an exempted company’s register of members is not open to inspection;

•

an exempted company does not have to hold an annual general meeting;

•

an exempted company may issue no par value, negotiable or bearer shares;

•

an exempted company may obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 20 years in the first instance);

•

an exempted company may register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands;

•

an exempted company may register as a limited duration company; and

•

an exempted company may register as a segregated portfolio company.

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company. We are subject to reporting and other informational requirements of the Exchange Act, as applicable to foreign private issuers. We currently comply with the Nasdaq Stock Market Rules in lieu of following home country practice. The Nasdaq Stock Market Rules require that every company listed on the Nasdaq hold an annual general meeting of shareholders. In addition, our Articles of Association allow directors to call special meeting of shareholders pursuant to the procedures set forth in our Articles.

Differences in Corporate Law

S-50

TABLE OF CONTENTS

Companies Act and the current Companies Act of England. In addition, the Companies Act differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of certain significant differences between the provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in the State of Delaware in the United States and their shareholders.

Mergers and Similar Arrangements.

The Companies Act permits mergers between Cayman Islands companies and between Cayman Islands companies and non-Cayman Islands companies. In order to effect such a merger, the directors of each constituent company must approve a written plan of merger, which must then be authorized by (a) a special resolution of the shareholders of each constituent company, and (b) such other authorization, if any, as may be specified in such constituent company’s articles of association. The plan must be filed with the Registrar of Companies of the Cayman Islands together with a declaration as to the solvency of the surviving company, a list of the assets and liabilities of each constituent company and an undertaking that a copy of the certificate of merger will be given to the members and creditors of each constituent company and that notification of the merger will be published in the Cayman Islands Gazette. Court approval is not required for a merger which is effected in compliance with these statutory procedures.

A merger between a Cayman parent company and its Cayman subsidiary or subsidiaries does not require authorization by a resolution of shareholders. For this purpose a subsidiary is a company of which at least ninety percent (90%) of the issued shares entitled to vote are owned by the parent company.

The consent of each holder of a fixed or floating security interest over a constituent company is required unless this requirement is waived by a court in the Cayman Islands.

Save in certain limited circumstances, a dissentient shareholder of a Cayman constituent company is entitled to payment of the fair value of his shares upon dissenting to a merger or consolidation. The exercise of appraisal rights will preclude the exercise of any other rights save for the right to seek relief on the grounds that the merger or consolidation is void or unlawful.

In addition, there are statutory provisions that facilitate the reconstruction and amalgamation of companies by way of schemes of arrangement, provided that the arrangement is approved by a majority in number, representing 75 per cent. in value of each class of shareholders and creditors with whom the arrangement is to be made. The convening of the meetings and subsequently the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder has the right to express to the court the view that the transaction ought not to be approved, the court can be expected to approve the arrangement if it determines that:

•

the statutory provisions as to the required majority vote have been met;

•

the shareholders have been fairly represented at the meeting in question and the statutory majority are acting bona fide without coercion of the minority to promote interests adverse to those of the class;

•

the arrangement is such that may be reasonably approved by an intelligent and honest man of that class acting in respect of his interest; and

•

the arrangement is not one that would more properly be sanctioned under some other provision of the Companies Act.

When a take over offer is made and accepted by holders of 90% of the shares the subject of the offer within four months, the offeror may, within a two-month period commencing on the expiration of such four month period, require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands but this is unlikely to succeed in the case of an offer which has been so approved unless there is evidence of fraud, bad faith or collusion.

If an arrangement and reconstruction by way of scheme of arrangement is thus approved and sanctioned or general offer is made and accepted, the dissenting shareholder would have no rights comparable to appraisal rights, which would otherwise ordinarily be available to dissenting shareholders of Delaware corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

TABLE OF CONTENTS

The Companies Act also contains statutory provisions which provide that a company may present a petition to the Grand Court of the Cayman Islands for the appointment of a restructuring officer on the grounds that the company (a) is or is likely to become unable to pay its debts within the meaning of section 93 of the Companies Act; and (b) intends to present a compromise or arrangement to its creditors (or classes thereof) either, pursuant to the Companies Act, the law of a foreign country or by way of a consensual restructuring. The petition may be presented by a company acting by its directors, without a resolution of its members or an express power in its articles of association. On hearing such a petition, the Cayman Islands court may, among other things, make an order appointing a restructuring officer or make any other order as the court thinks fit.

Shareholders’ Suits.

In principle, we will normally be the proper plaintiff and as a general rule a derivative action may not be brought by a minority shareholder. However, based on English authorities, which would in all likelihood be of persuasive authority in the Cayman Islands, the Cayman Islands courts can be expected to follow and apply the common law principles (namely the rule in Foss v. Harbottle and the exceptions thereto) so that a non-controlling shareholder may be permitted to commence a class action against or derivative actions in the name of the company to challenge actions where:

•

a company acts or proposes to act illegally or ultra vires;

•

the act complained of, although not ultra vires, could only be effected duly if authorized by more than a simple majority vote that has not been obtained; and

•

those who control the company are perpetrating a “fraud on the minority.”

Indemnification of Directors and Executive Officers and Limitation of Liability.

Cayman Islands law does not limit the extent to which a company’s articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. Our Memorandum and Articles of Association permit indemnification of officers and directors for losses, damages, costs and expenses incurred in their capacities as such unless such losses or damages arise from dishonesty or fraud which may attach to such directors or officers. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation. In addition, we have entered into indemnification agreements with our directors and senior executive officers that will provide such persons with additional indemnification beyond that provided in our Memorandum and Articles of Association.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us under the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Directors’ Fiduciary Duties.

Under Delaware corporate law, a director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components: the duty of care and the duty of loyalty. The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he or she reasonably believes to be in the best interests of the corporation. He or she must not use his or her corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

S-52

TABLE OF CONTENTS

As a matter of Cayman Islands law, a director of a Cayman Islands company is in the position of a fiduciary with respect to the company and therefore it is considered that he owes the following duties to the company — a duty to act bona fide in the best interests of the company, a duty not to make a profit based on his or her position as director (unless the company permits him to do so) and a duty not to put himself in a position where the interests of the company conflict with his or her personal interest or his or her duty to a third party. A director of a Cayman Islands company owes to the company a duty to act with skill and care. It was previously considered that a director need not exhibit in the performance of his or her duties a greater degree of skill than may reasonably be expected from a person of his or her knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care and these authorities are likely to be followed in the Cayman Islands.

Shareholder Action by Written Consent

Under the Delaware General Corporation Law, a corporation may eliminate the right of shareholders to act by written consent by amendment to its certificate of incorporation. Our Memorandum and Articles of Association expressly provide that shareholders may not approve corporate matters by way of a unanimous written resolution signed by or on behalf of each shareholder who would have been entitled to vote on such matter at a general meeting without a meeting being held.

Shareholder Proposals.

Under the Delaware General Corporation Law, a shareholder has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the governing documents. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.

Cayman Islands law does not provide for the right for shareholders to requisition a shareholders’ meeting. As an exempted Cayman Islands company, we are not obliged by law to call shareholders’ annual general meetings. However, our Memorandum and Articles of Association allow shareholder requisitions of general meetings under certain circumstances.

Cumulative Voting.

Under the Delaware General Corporation Law, cumulative voting for elections of directors is not permitted unless the corporation’s certificate of incorporation specifically provides for it. Cumulative voting potentially facilitates the representation of minority shareholders on a board of directors since it permits the minority shareholder to cast all the votes to which the shareholder is entitled on a single director, which increases the shareholder’s voting power with respect to electing such director. As permitted under Cayman Islands law, our Memorandum and Articles of Association do not provide for cumulative voting. As a result, our shareholders are not afforded any less protections or rights on this issue than shareholders of a Delaware corporation.

Removal of Directors.

Under the Delaware General Corporation Law, a director of a corporation with a classified board may be removed only for cause with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Under our Memorandum and Articles of Association, subject to the enumerated appointment and nomination rights provided to certain of our shareholders, any director (other than Mr. William Wei Huang (for so long as he is a director) and any directors appointed by STT Garnet) may be removed by way of a special resolution of the shareholders.

Transactions with Interested Shareholders.

The Delaware General Corporation Law contains a business combination statute applicable to Delaware corporations whereby, unless the corporation has specifically elected not to be governed by such statute by amendment to its certificate of incorporation, it is prohibited from engaging in certain business combinations with an “interested shareholder” for three years following the date that such person becomes an interested shareholder. An interested shareholder generally is a person or a group who or which owns or owned 15% or more of the target’s outstanding voting stock within the past three years. This has the effect of limiting the

S-53

TABLE OF CONTENTS

ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which such shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware corporation to negotiate the terms of any acquisition transaction with the target’s board of directors.

Cayman Islands law has no comparable statute. As a result, we cannot avail ourselves of the types of protections afforded by the Delaware business combination statute. However, although Cayman Islands law does not regulate transactions between a company and its significant shareholders, it does provide that such transactions must be entered into bona fide in the best interests of the company and for a proper corporate purpose and not with the effect of constituting a fraud on the minority shareholders.

Dissolution; Winding Up.

Under the Delaware General Corporation Law, unless the board of directors approves the proposal to dissolve, dissolution must be approved by shareholders holding 100% of the total voting power of the corporation. Only if the dissolution is initiated by the board of directors may it be approved by a simple majority of the corporation’s outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board. Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members or, if the company is unable to pay its debts as they fall due, by an ordinary resolution of its members. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so.

Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so. Under our Memorandum and Articles of Association, the Board shall have power in the name and on behalf of the Company to present a petition to the court for the Company to be wound up, or our company may be dissolved, liquidated or wound up by the vote of holders of seventy five per cent. of our shares voting at a meeting.

Variation of Rights of Shares.

Under the Delaware General Corporation Law, a corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of such class, unless the certificate of incorporation provides otherwise. Under Cayman Islands law and our Articles of Association, if our share capital is divided into more than one class of shares, we may vary the rights attached to any class only with the sanction of a special resolution passed at a general meeting of the holders of the shares of that class and only with the approval of the holders of such class.

Amendment of Governing Documents.

Under the Delaware General Corporation Law, a corporation’s governing documents may be amended with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. As permitted by Cayman Islands law, our Memorandum and Articles of Association may only be amended by special resolution.

Rights of Non-Resident or Foreign Shareholders.

There are no limitations imposed by our Memorandum and Articles of Association on the rights of non-resident or foreign shareholders to hold or exercise voting rights on our shares. In addition, there are no provisions in our Memorandum and Articles of Association governing the ownership threshold above which shareholder ownership must be disclosed.

Directors’ Power to Issue Shares.

Subject to applicable law, our board of directors is empowered to issue or allot shares or grant options and warrants with or without preferred, deferred, qualified or other special rights or restrictions.

UNDERWRITING (CONFLICTS OF INTEREST)

The Borrowed ADSs being offered under this prospectus supplement and the accompanying prospectus are ADSs that we have agreed pursuant to the ADS Lending Agreement to loan to J.P. Morgan Securities plc (the “ADS Borrower”), an affiliate of J.P. Morgan Securities LLC, which is acting as the underwriter in this offering (the “Borrowed ADS Underwriter”). We have entered into an underwriting agreement with the Borrowed ADS Underwriter and the ADS Borrower, with respect to this offering of the Borrowed ADSs by the ADS Borrower as listed below.

Underwriter			Number of Borrowed ADSs offered
J.P. Morgan Securities LLC

The Borrowed ADSs will initially be offered at US$ per ADS, which we refer to as the Delta Placement of Borrowed ADSs.

The Borrowed ADSs will be offered through the Borrowed ADS Underwriter, either directly or indirectly through its U.S. broker-dealer affiliates, or such other registered dealers as may be designated by the Borrowed ADS Underwriter, and these dealers may receive compensation in the form of discounts, concessions or commissions from the ADS Borrower (or its affiliate) and/or from purchasers of Borrowed ADSs for whom the dealers may act as agents or to whom they may sell as principals. Sale of any Borrowed ADSs made outside of the United States may be made by an affiliate of the underwriter. The ADS Borrower or its affiliates will use the short positions resulting from the Delta Placement of the Borrowed ADSs to facilitate privately negotiated derivative transactions, by which certain investors in our convertible senior notes, who employ a convertible arbitrage strategy, will hedge their market risk with respect to the convertible senior notes. These derivative transactions are expected to be on market-standard terms for such type of transactions. During the term of such transactions, such investors may use their synthetic short positions established thereunder at their sole discretion. See “Description of the Delta Placement of Borrowed ADSs and Concurrent Offering of Convertible Senior Notes.”

The ADS Borrower, or its affiliates, will receive all of the proceeds from the sale of the Borrowed ADSs. While we will not receive any proceeds from the sale of the Borrowed ADSs, under the ADS Lending Agreement, we will receive a nominal processing fee for the use of such Borrowed ADSs of US$0.0004 per ADS from the ADS Borrower or its affiliates.

Our ADSs are listed on The Nasdaq Global Market under the symbol “GDS” and our Class A ordinary share are listed on the Main Board of the Hong Kong Stock Exchange under the stock code “9698.”

We have agreed to indemnify the initial purchaser of the convertible senior notes, and the ADS Borrower and the Borrowed ADS Underwriter against some specified types of liabilities, including liabilities under the Securities Act, and to contribute to payments the initial purchaser of the convertible senior notes or the ADS Borrower and the Borrowed ADS Underwriter may be required to make in respect of any of these liabilities.

Other Relationships

The Borrowed ADS Underwriter, the ADS Borrower and certain of their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

The Borrowed ADS Underwriter is an underwriter in the offering of Primary ADSs. An affiliated of the ADS Borrower and is an initial purchaser of the convertible senior notes concurrently offered under Rule 144A. In addition, the ADS Borrower, an affiliate of J.P. Morgan Securities LLC, i.e, the Borrowed ADS Underwriter, has entered into the ADS Lending Agreement with us. See above under “Description of the Delta Placement of Borrowed ADSs and Concurrent Offering of Convertible Senior Notes.”

The Borrowed ADS Underwriter, the ADS Borrower and certain of their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage activities.

In addition, in the ordinary course of their various business activities, the Borrowed ADS Underwriter, the ADS Borrower and certain of their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments issued by us and our affiliates. The Borrowed ADS Underwriter, the ADS Borrower and certain of their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to customers that they acquire, long and/or short positions in such securities and instruments.

Expenses

The expenses of this offering and the concurrent offering of our convertible senior notes that are payable by us are estimated to be US$ million (excluding the initial purchaser’s discounts and commissions payable in connection with the concurrent offering of convertible senior notes). We have also agreed to reimburse the ADS Borrower and the Borrowed ADS Underwriter for certain of their expenses in an amount up to US$ .

Concurrent Notes Offering

S-57

TABLE OF CONTENTS

our % convertible senior notes due 2032 (the “convertible senior notes” and the “Concurrent Notes Offering”, respectively) described below, who employ a convertible arbitrage strategy, will hedge their market risk with respect to the convertible senior notes. These derivative transactions are expected to be on market-standard terms for such type of transactions. During the term of such transactions, such investors may use their synthetic short positions established thereunder at their sole discretion.

J.P. Morgan Securities LLC, an affiliate of the ADS Borrower, is acting as the underwriter in the Delta Placement of Borrowed ADSs (the “Borrowed ADS Underwriter”), as an underwriter in the offering of Primary ADSs.

Conflicts of Interest

All of the proceeds of the offering of the Borrowed ADSs will be paid to the Borrowed ADS Underwriter or affiliates thereof. As a result, the Borrowed ADS Underwriter, or affiliates thereof, will each receive 5% or more of the net proceeds of this offering. Thus, the Borrowed ADS Underwriter has a “conflict of interest” as defined in FINRA Rule 5121. Accordingly, this offering will be made in compliance with the requirements of FINRA Rule 5121. The appointment of a “qualified independent underwriter” is not required in connection with this offering as a “bona fide public market” as defined in FINRA Rule 5121, exists for the ADSs. In accordance with FINRA Rule 5121, no Borrowed ADS Underwriter will make sales to any account over which it exercises discretionary authority without the specific written approval of the transaction from the account holder.

Stabilization, Short Positions and Penalty Bids

The Borrowed ADS Underwriter will not engage in any stabilizing transactions in connection with the Delta Placement of the Borrowed ADSs.

However, in connection with the Concurrent Primary ADSs Offering, the underwriters for that offering may engage in stabilizing transactions, which may involve making bids for, purchasing and selling ADSs in the open market for the purpose of preventing or retarding a decline in the market price of the ADSs while this offering is in progress. These stabilizing transactions may include making short sales of ADSs, which involves the sale by such underwriters of a greater number of ADSs than they are required to purchase in the Concurrent Primary ADSs Offering, and purchasing ADSs on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional ADSs referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters of the Concurrent Primary ADSs Offering may close out any covered short position either by exercising their option to purchase additional ADSs in the Concurrent Primary ADSs Offering, in whole or in part, or by purchasing ADSs in the open market. In making this determination, the underwriters of the Concurrent Primary ADSs Offering will consider, among other things, the price of ADSs available for purchase in the open market compared to the price at which the underwriters may purchase ADSs through the option to purchase additional ADSs. A naked short position is more likely to be created if the underwriters of the Concurrent Primary ADSs Offering are concerned that there may be downward pressure on the price of the ADSs in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters of the Concurrent Primary Offering create a naked short position, they will purchase ADSs in the open market to cover the position.

The underwriters of the Concurrent Primary ADSs Offering may also engage in other activities that stabilize, maintain or otherwise affect the price of the ADSs, including the imposition of penalty bids. This means that if the representatives of the underwriters of the Concurrent Primary ADSs Offering purchase ADSs in the

S-58

TABLE OF CONTENTS

open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those ADSs as part of the Concurrent Primary ADSs Offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the ADSs or preventing or retarding a decline in the market price of the ADSs, and, as a result, the price of the ADSs may be higher than the price that otherwise might exist in the open market. These activities may be commenced and discontinued at any time. The underwriters of the Concurrent Primary ADSs Offering may carry out these transactions on the Nasdaq Global Market, in the over the counter market or otherwise.

Selling Restrictions

With respect to offers and sales of our securities that are the subject of this prospectus supplement:

United Kingdom

An offer to the public of any ADSs may not be made in the United Kingdom, except that an offer to the public in the United Kingdom of any ADSs may be made at any time under the following exemptions under the UK Prospectus Regulation:

(a)

to any legal entity which is a “qualified investor” as defined under the UK Prospectus Regulation;

(b)

to fewer than 150 natural or legal persons (other than “qualified investors” as defined under the UK Prospectus Regulation), subject to obtaining the prior consent of the underwriter for any such offer; or

(c)

in any other circumstances falling within section 86 of the Financial Services and Markets Act 2000 (as amended, “FSMA”);

provided that no such offer of ADSs shall result in a requirement for the issuer or any underwriter to publish a prospectus pursuant to section 85 of the FSMA or a supplemental prospectus pursuant to Article 23 of the UK Prospectus Regulation and each person who initially acquires any ADSs or to whom any offer is made will be deemed to have represented, warranted and agreed to and with each of the underwriter and the issuer that it is a qualified investor within the meaning of Article 2 of the UK Prospectus Regulation.

In the case of any ADSs being offered to a financial intermediary as that term is used in Article 1(4) of the UK Prospectus Regulation, each financial intermediary will also be deemed to have represented, warranted and agreed that the ADSs acquired by it in the offer have not been acquired on a non-discretionary basis on behalf of, nor have they been acquired with a view to their offer or resale to, persons in circumstances which may give rise to an offer of any ADSs to the public, other than their offer or resale in the United Kingdom to qualified investors as so defined or in circumstances in which the prior consent of the underwriter has been obtained to each such proposed offer or resale.

The issuer, the underwriter and their affiliates will rely upon the truth and accuracy of the foregoing representations, warranties and agreements. Notwithstanding the above, a person who is not a “qualified investor” and who has notified the underwriter of such fact in writing may, with the prior consent of the underwriter, be permitted to acquire ADSs in the offer.

For the purposes of this provision, the expression an “offer to the public” in relation to any ADSs in the United Kingdom means the communication in any form and by any means of sufficient information on the terms of the offer and any ADSs to be offered so as to enable an investor to decide to purchase or subscribe for any ADSs, and the expression “UK Prospectus Regulation” means Regulation (EU) 2017/ 1129 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018.

European Economic Area

The ADSs are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”) or in the United Kingdom. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer

S-59

TABLE OF CONTENTS

within the meaning of Directive 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2017/1129 (as amended or superseded, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the ADSs or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the ADSs or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement has been prepared on the basis that any offer of ADSs in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Regulation, from the requirement to publish a prospectus for offers of ADSs.

This prospectus supplement is not a prospectus for the purposes of the Prospectus Regulation. This prospectus supplement has been prepared on the basis that any offer of ADSs in any Member State of the EEA or the United Kingdom will be made pursuant to an exemption under the Prospectus Regulation from a requirement to publish a prospectus for offers of ADSs. This prospectus supplement is not a prospectus for the purpose of the Prospectus Regulation.

Hong Kong

The ADSs may not be offered or sold in Hong Kong by means of any document other than (i) in circumstances which do not constitute an offer to the public within the meaning of the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32 of the Laws of Hong Kong) (“Companies (Winding Up and Miscellaneous Provisions) Ordinance”), or (ii) to “professional investors” as defined in the Securities and Futures Ordinance (Cap. 571 of the Laws of Hong Kong) (“Securities and Futures Ordinance”) and any rules made thereunder, or (iii) in other circumstances which do not result in the document being a “prospectus” as defined in the Companies (Winding Up and Miscellaneous Provisions) Ordinance, and no advertisement, invitation or document relating to the ADSs may be issued or may be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the securities laws of Hong Kong) other than with respect to ADSs which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” in Hong Kong as defined in the Securities and Futures Ordinance and any rules made thereunder.

Japan

The securities have not been and will not be registered under the Financial Instruments and Exchange Act of Japan (Act No. 25 of 1948, as amended), or the FIEA. The securities may not be offered or sold, directly or indirectly, in Japan or to or for the benefit of any resident of Japan (including any person resident in Japan or any corporation or other entity organized under the laws of Japan) or to others for reoffering or resale, directly or indirectly, in Japan or to or for the benefit of any resident of Japan, except pursuant to an exemption from the registration requirements of the FIEA and otherwise in compliance with any relevant laws and regulations of Japan.

Singapore

This prospectus supplement has not been registered as a prospectus with the Monetary Authority of Singapore. Accordingly, this prospectus supplement and any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of the ADSs may not be circulated or distributed, nor may the ADSs be offered or sold, or be made the subject of an invitation for subscription or purchase, whether directly or indirectly, to persons in Singapore other than (i) to an institutional investor (as defined in Section 4A of the Securities and Futures Act, Chapter 289 of Singapore, as modified or amended from time to time including by any subsidiary legislation as may be applicable at the relevant time (together, the “SFA”), under Section 274 of the SFA, (ii) to a relevant person (as defined in Section 275(2) of the SFA) pursuant to Section 275(1) of the SFA, or any person pursuant to Section 275(1A) of the SFA, and in accordance with the conditions specified in Section 275 of the SFA or (iii) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the SFA, in each case subject to conditions set forth in the SFA.

TABLE OF CONTENTS

TAXATION

This summary is based on the laws of the Cayman Islands, the PRC, Hong Kong and the United States in effect on the date of this prospectus supplement, which are subject to changes (or changes in interpretation), possibly with retroactive effect. This discussion does not purport to be a comprehensive description of all the tax considerations that may be relevant to a decision to acquire, own or dispose of our ADSs or Class A ordinary shares and does not purport to deal with consequences applicable to all categories of investors, some of which may be subject to special rules. Prospective investors are urged to consult their tax advisors regarding the tax consequences of owning and disposing of our ADSs or Class A ordinary shares.

Cayman Islands Taxation

The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty or withholding tax applicable to us or to any holder of our ADSs or ordinary shares. There are no other taxes likely to be material to us levied by the Government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or after execution brought within the jurisdiction of, the Cayman Islands. No stamp duty is payable in the Cayman Islands on the issue of shares by, or any transfer of shares of, Cayman Islands companies except those which hold interests in land in the Cayman Islands. The Cayman Islands is a party to a double tax treaty entered with the United Kingdom in 2010 but is otherwise not party to any double tax treaties. There are no exchange control regulations or currency restrictions in the Cayman Islands.

Payments of dividends and capital in respect of our ADSs and ordinary shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of our ADSs or ordinary shares, as the case may be, nor will gains derived from the disposal of our ADSs or ordinary shares be subject to Cayman Islands income or corporation tax.

Pursuant to Section 6 of the Tax Concessions Act (1999 Revision) of the Cayman Islands, we have obtained an undertaking from the Governor-in-Council:

(1)

that no law which is enacted in the Cayman Islands imposing any tax to be levied on profits or income or gains or appreciation shall apply to us or our operations; and

(2)

that the aforesaid tax or any tax in the nature of estate duty or inheritance tax shall not be payable on our shares, debentures or other obligations.

The undertaking for us is for a period of twenty years from December 19, 2006.

People’s Republic of China Taxation

In March 2007, the National People’s Congress of China enacted the PRC Enterprise Income Tax Law, which became effective on January 1, 2008, and was most recently amended on February 24, 2017 and on December 29, 2018. The PRC Enterprise Income Tax Law provides that enterprises organized under the laws of jurisdictions outside China with their “de facto management bodies” located within China may be considered PRC resident enterprises and therefore subject to PRC enterprise income tax at the rate of 25% on their worldwide income. The Implementing Rules of the PRC Enterprise Income Tax Law further defines the term “de facto management body” as the management body that exercises substantial and overall management and control over the business, personnel, accounts and properties of an enterprise. While we do not currently consider our company or any of our overseas subsidiaries to be a PRC resident enterprise, there is a risk that the PRC tax authorities may deem our company or any of our overseas subsidiaries as a PRC resident enterprise since a substantial majority of the members of our management team as well as the management team of some of our overseas subsidiaries are located in China, in which case we or the overseas subsidiaries, as the case may be, would be subject to the PRC enterprise income tax at the rate of 25% on worldwide income.

If the PRC tax authorities determine that our Cayman Islands holding company is a “resident enterprise” for PRC enterprise income tax purposes, a number of unfavorable PRC tax consequences could follow. One example is a 10% withholding tax would be imposed on dividends we pay to our non-PRC enterprise shareholders and with respect to gains derived by our non-PRC enterprise shareholders from transferring our ordinary shares or ADSs. Furthermore, if we are deemed a PRC resident enterprise, dividends paid to

S-64

TABLE OF CONTENTS

individual investors who are non-PRC residents and any gain realized on the transfer of ADSs or ordinary shares by such investors may be subject to PRC tax (which in the case of dividends may be withheld at source) at a rate of 20%. It is unclear whether, if we are treated as a PRC resident enterprise, holders of our ordinary shares or ADSs would be able to claim the benefit of income tax treaties or agreements entered into between China and other countries or areas.

Hong Kong Taxation

Our subsidiaries incorporated in Hong Kong were subject to Hong Kong profits tax at a rate of 16.5% in the fiscal years ended December 31, 2022, 2023 and 2024. GDS Holdings was subject to Hong Kong profits tax at a rate of 16.5% in the fiscal years ended December 31, 2022, 2023 and 2024.

Our principal register of members is maintained by our Principal Share Registrar in the Cayman Islands, and our Hong Kong register of members is maintained by the Hong Kong Share Registrar in Hong Kong.

Dealings in our Class A ordinary shares registered on our Hong Kong share register are subject to Hong Kong stamp duty. The stamp duty is charged to each of the seller and purchaser at the rate of 0.13% of the consideration for, or (if greater) the value of, our Class A ordinary shares transferred. In other words, a total of 0.26% is currently payable on a typical sale and purchase transaction of our Class A ordinary shares. In addition, a fixed duty of HK$5.00 is charged on each instrument of transfer (if required).

To facilitate ADS-Class A ordinary share conversion and trading between the Nasdaq and the Hong Kong Stock Exchange, we have moved a portion of our issued ordinary shares from our Cayman share register to our Hong Kong share register. It is unclear whether, as a matter of Hong Kong law, the trading or conversion of ADSs constitutes a sale or purchase of the underlying Hong Kong-registered ordinary shares that is subject to Hong Kong stamp duty. We advise investors to consult their own tax advisors on this matter. See “Item 3. Key Information — D. Risk Factors — Risks Related to Our ADSs and Class A Ordinary Shares — There is uncertainty as to whether Hong Kong stamp duty will apply to the trading or conversion of our ADSs.” in our 2024 Annual Report.

U.S. Federal Income Tax Considerations

The following discussion is a summary of certain U.S. federal income tax considerations relating to the ownership and disposition of our ADSs and Class A ordinary shares. This discussion applies only to U.S. holders (as defined below) that acquire our ADSs pursuant to this offering and hold our ADSs or Class A ordinary shares (as applicable) as capital assets for U.S. federal income tax purposes (generally, property held for investment).

As used herein, the term “U.S. holder” means a beneficial owner of our ADSs or Class A ordinary shares that is, for U.S. federal income tax purposes, any of the following:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•

an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust if it (1) is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

This discussion is based upon provisions of the United States Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations thereunder, rulings and administrative pronouncements of the Internal Revenue Service (the “IRS”), judicial decisions and the income tax treaty between the United States and the PRC (the “Treaty”), all as currently in effect as of the date hereof. Those authorities may be changed or subject to different interpretation, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those summarized below. In addition, this discussion assumes that the deposit agreement, and all other related agreements, will be performed in accordance with their terms.

S-65

TABLE OF CONTENTS

This discussion does not represent a detailed description of the U.S. federal income tax consequences applicable to you if you are subject to special treatment under the U.S. federal income tax laws, including if you are:

•

a dealer in securities or currencies;

•

a financial institution;

•

a regulated investment company;

•

a real estate investment trust;

•

an insurance company;

•

a tax-exempt organization;

•

a person holding our ADSs or Class A ordinary shares as part of a hedging, integrated or conversion transaction, a constructive sale or a straddle;

•

a trader in securities that has elected the mark-to-market method of accounting for your securities;

•

a person liable for any alternative minimum tax;

•

a person who owns or is deemed to own 10% or more of our stock (by vote or value);

•

a person required to accelerate the recognition of any item of gross income with respect to our ADSs or Class A ordinary shares as a result of such income being recognized on an applicable financial statement;

•

a partnership or other pass-through entity for U.S. federal income tax purposes; or

•

a person whose “functional currency” is not the U.S. dollar.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our ADSs or Class A ordinary shares, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner of a partnership holding our ADSs or Class A ordinary shares, you should consult your tax advisors regarding the tax considerations applicable to you.

This discussion does not contain a detailed description of all the U.S. federal income tax consequences to you in light of your particular circumstances and does not address the Medicare tax on net investment income, U.S. federal estate and gift taxes, or the effects of any state, local or non-U.S. tax laws. It is not intended to be, and should not be construed to be, legal or tax advice to any particular investor in our ADSs or Class A ordinary shares. If you are considering the acquisition of our ADSs, you should consult your own tax advisors concerning the particular U.S. federal income tax consequences to you in light of your particular situation as well as any consequences arising under other U.S. federal tax laws, the laws of any other taxing jurisdiction, and any applicable tax treaties.

ADSs

If you hold ADSs, for U.S. federal income tax purposes, you generally will be treated as the owner of the underlying Class A ordinary shares that are represented by such ADSs. Accordingly, deposits or withdrawals of Class A ordinary shares for ADSs will not be subject to U.S. federal income tax.

Taxation of Dividends

Subject to the discussion under “— Passive Foreign Investment Company Considerations” below, the gross amount of any distributions (other than certain pro rata distributions of our shares) on the ADSs or Class A ordinary shares (including any amounts withheld to reflect PRC withholding taxes) will be taxable as dividends, to the extent paid out of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Such income (including withheld taxes) will be includable in your gross income as ordinary income on the day actually or constructively received by you, in the case of the Class A ordinary shares, or by the depositary, in the case of ADSs. Such dividends will not be eligible for the dividends received deduction generally allowed to corporations under the Code.

S-66

TABLE OF CONTENTS

Subject to applicable limitations (including a minimum holding period requirement), dividends received by non-corporate U.S. holders from a qualified foreign corporation may be treated as “qualified dividend income” that is subject to reduced rates of taxation. A foreign corporation is generally treated as a qualified foreign corporation with respect to dividends paid by that corporation on ordinary shares (or ADSs backed by such shares) that are readily tradable on an established securities market in the United States. U.S. Treasury Department guidance indicates that our ADSs, which are listed on the Nasdaq, are readily tradable on an established securities market in the United States. Thus, subject to the discussion under “— Passive Foreign Investment Company Considerations” below, we believe that dividends we pay on our ADSs will be eligible for the reduced tax rates. Since we do not expect that our Class A ordinary shares will be listed on an established securities market in the United States, we do not believe that dividends that we pay on our Class A ordinary shares that are not represented by ADSs will meet the conditions required for these reduced tax rates. There also can be no assurance that our ADSs will continue to be readily tradable on an established securities market in the United States in later years. Consequently, there can be no assurance that our ADSs will continue to be eligible for the reduced tax rates. A qualified foreign corporation also generally includes a foreign corporation that is eligible for the benefits of certain income tax treaties with the United States. In the event that we are deemed to be a PRC resident enterprise under the PRC tax law (see “— People’s Republic of China Taxation” above), we may be eligible for the benefits of the Treaty. In that case, dividends we pay on our Class A ordinary shares would be eligible for the reduced rates of taxation whether or not the shares are readily tradable on an established securities market in the United States, and whether or not the shares are represented by ADSs. You should consult your own tax advisors regarding the application of these rules given your particular circumstances.

Notwithstanding the foregoing, we will not be treated as a qualified foreign corporation, and non-corporate U.S. holders will not be eligible for reduced rates of taxation, for any dividends that we pay if we are a passive foreign investment company (a “PFIC”) in the taxable year in which such dividends are paid or in the preceding taxable year (see “— Passive Foreign Investment Company Considerations” below).

In the event that we are deemed to be a PRC resident enterprise under the PRC tax law, you may be subject to PRC withholding taxes on dividends paid to you with respect to the ADSs or Class A ordinary shares. See “— People’s Republic of China Taxation” above. In that case, subject to certain conditions and limitations (including a minimum holding period requirement), PRC withholding taxes on dividends may be treated as foreign taxes eligible for credit against your U.S. federal income tax liability. For purposes of calculating the foreign tax credit, dividends paid on the ADSs or Class A ordinary shares will be treated as foreign source income and will generally constitute “passive category income.” However, if you are eligible for Treaty benefits, any PRC withholding taxes on dividends will not be creditable against your U.S. federal income tax liability to the extent withheld at a rate exceeding any applicable Treaty rate. In addition, U.S. Treasury regulations addressing foreign tax credits (the “Foreign Tax Credit Regulations”) impose additional requirements for foreign taxes to be eligible for a foreign tax credit, and unless you are eligible for and elect to claim the benefits of the Treaty, there can be no assurance that those requirements will be satisfied. The Department of the Treasury and the IRS are considering proposing amendments to the Foreign Tax Credit Regulations. In addition, recent notices from the IRS provide temporary relief by allowing taxpayers that comply with applicable requirements to apply many aspects of the foreign tax credit regulations as they previously existed (before the release of the current Foreign Tax Credit Regulations) for taxable years ending before the date that a notice or other guidance withdrawing or modifying the temporary relief is issued (or any later date specified in such notice or other guidance). Alternatively, instead of claiming a foreign tax credit, you may be able to deduct any PRC withholding taxes in computing your taxable income, subject to generally applicable limitations under U.S. law (including that a U.S. holder is not eligible for a deduction for otherwise creditable foreign income taxes paid or accrued in a taxable year if such U.S. holder claims a foreign tax credit for any foreign income taxes paid or accrued in the same taxable year). The rules governing the foreign tax credit and deductions for foreign taxes are complex. You are urged to consult your tax advisors regarding the availability of the foreign tax credit or a deduction under your particular circumstances.

To the extent that the amount of any distribution exceeds our current and accumulated earnings and profits, as determined under U.S. federal income tax principles, the distribution ordinarily would be treated, first, as a tax-free return of capital, causing a reduction in the adjusted basis of the ADSs or Class A ordinary shares (thereby increasing the amount of gain, or decreasing the amount of loss, to be recognized by you on a subsequent disposition of the ADSs or Class A ordinary shares), and, second, the balance in excess of adjusted

S-67

TABLE OF CONTENTS

basis ordinarily would be taxed as capital gain recognized on a sale or exchange. However, we do not expect to determine our earnings and profits in accordance with U.S. federal income tax principles. Therefore, you should expect that distributions will generally be reported to the IRS and taxed to you as dividends (as discussed above), even if they might ordinarily be treated as a tax-free return of capital or as capital gain.

Sale, Exchange or Other Taxable Disposition of ADSs or Class A Ordinary Shares

For U.S. federal income tax purposes, you will generally recognize taxable gain or loss on any sale, exchange or other taxable disposition of ADSs or Class A ordinary shares in an amount equal to the difference between the amount realized for the ADSs or Class A ordinary shares (net of any Hong Kong stamp duty imposed on such proceeds) and your adjusted basis in the ADSs or Class A ordinary shares (which should similarly take into account any Hong Kong stamp duty paid in connection with the acquisition of the ADSs or Class A ordinary shares), both as determined in U.S. dollars. Subject to the discussion under “— Passive Foreign Investment Company Considerations” below, such gain or loss will generally be capital gain or loss and will generally be long-term capital gain or loss if you have held the ADSs or Class A ordinary shares for more than one year. Long-term capital gains of non-corporate U.S. holders (including individuals) are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Any gain or loss recognized by you will generally be treated as U.S. source gain or loss for foreign tax credit purposes. However, if we are treated as a PRC resident enterprise for PRC tax purposes and PRC tax is imposed on any gain, and if you are eligible for the benefits of the Treaty, you may elect to treat such gain as PRC source gain under the Treaty. If you are not eligible for the benefits of the Treaty or you fail to make the election to treat any gain as PRC source, then you generally would not be able to use a foreign tax credit for any PRC tax imposed on the disposition of our ADSs or Class A ordinary shares unless such credit can be applied (subject to applicable limitations) against U.S. federal income tax due on other income derived from foreign sources in the same income category (generally, the passive category). However, pursuant to the Foreign Tax Credit Regulations, unless you are eligible for and elect to claim the benefits of the Treaty, any such PRC tax would generally not be a foreign income tax eligible for a foreign tax credit (regardless of any other income that you may have that is derived from foreign sources). In such case, the non-creditable PRC tax may reduce the amount realized on the sale, exchange or other taxable disposition of the ADSs or Class A ordinary shares. As discussed above, however, recent notices from the IRS provide temporary relief by allowing taxpayers that comply with applicable requirements to apply many aspects of the foreign tax credit regulations as they previously existed (before the release of the current Foreign Tax Credit Regulations) for taxable years ending before the date that a notice or other guidance withdrawing or modifying the temporary relief is issued (or any later date specified in such notice or other guidance). If any PRC tax is imposed on the sale, exchange or other taxable disposition of the ADSs or Class A ordinary shares and you apply such temporary relief, such PRC tax may be eligible for a foreign tax credit or deduction, subject to the applicable conditions and limitations.

You will be eligible for the benefits of the Treaty if, for purposes of the Treaty, you are a resident of the United States, and you meet other requirements specified in the Treaty. Because the determination of whether you qualify for the benefits of the Treaty is fact intensive and depends upon your particular circumstances, you are specifically urged to consult your tax advisors regarding your eligibility for the benefits of the Treaty. You are also urged to consult your tax advisors regarding the tax consequences if any PRC tax is imposed on gain on a disposition of our Class A ordinary shares or ADSs, including the availability of the foreign tax credit or a deduction and the election to treat any gain as PRC source, under your particular circumstances.

Passive Foreign Investment Company Considerations

Based on the past and projected composition of our income and assets and the valuation of our assets, we do not believe we were a PFIC for our most recent taxable year and we do not expect to be a PFIC for our current taxable year or in the foreseeable future, although there can be no assurance in this regard, since the determination of our PFIC status cannot be made until the end of a taxable year and depends significantly on the composition of our assets and income throughout the year.

In general, we will be a PFIC for any taxable year in which:

•

at least 75% of our gross income is passive income, or

S-68

TABLE OF CONTENTS

•

at least 50% of the value (generally based on a quarterly average) of our assets is attributable to assets that produce or are held for the production of passive income.

For this purpose, passive income generally includes dividends, interest, royalties and rents (other than royalties and rents derived in the active conduct of a trade or business and not derived from a related person), as well as gains from the sale of assets (such as stock) that produce passive income, foreign currency gains, and certain other categories of income. In addition, cash and other assets readily convertible into cash are generally considered passive assets. If we own at least 25% (by value) of the stock of another corporation, we will be treated, for purposes of determining whether we are a PFIC, as owning our proportionate share of the other corporation’s assets and receiving our proportionate share of the other corporation’s income. However, it is not entirely clear how the contractual arrangements between us and the VIEs will be treated for purposes of the PFIC rules. For U.S. federal income tax purposes, we consider ourselves to own the stock of the VIEs. If it is determined, contrary to our view, that we do not own the stock of the VIEs for U.S. federal income tax purposes (for instance, because the relevant PRC authorities do not respect these arrangements), that would alter the composition of our income and assets for purposes of testing our PFIC status, and may cause us to be treated as a PFIC.

The determination of whether we are a PFIC is made annually. Accordingly, it is possible that we may become a PFIC in the current or any future taxable year due to changes in our asset or income composition. The calculation of the value of our assets will be based, in part, on the quarterly market value of our ADSs, which is subject to change.

If we are a PFIC for any taxable year during which you hold our ADSs or Class A ordinary shares and you do not make a timely mark-to-market election, as described below, you will be subject to special — and generally very unfavorable — tax rules with respect to any “excess distribution” received and any gain realized from a sale or other disposition, including a pledge, of the ADSs or Class A ordinary shares. Distributions received in a taxable year with respect to the ADSs or Class A ordinary shares that are greater than 125% of the average annual distributions received during the shorter of the three preceding taxable years or your holding period for the ADSs or Class A ordinary shares will be treated as excess distributions. Under these special tax rules:

•

the excess distribution or gain will be allocated ratably over your holding period for the ADSs or Class A ordinary shares,

•

the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we were a PFIC, will be treated as ordinary income, and

the amount allocated to each other year will be subject to tax at the highest tax rate in effect for that year for individuals or corporations, as applicable, and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such year.

Although the determination of whether we are a PFIC is made annually, if we are a PFIC for any taxable year in which you hold our ADSs or Class A ordinary shares, you will generally be subject to the special tax rules described above for that year and for each subsequent year in which you hold the ADSs or Class A ordinary shares (even if we do not qualify as a PFIC in any subsequent years). However, if we cease to be a PFIC, you can avoid the continuing impact of the PFIC rules by making a special election to recognize gain as if your ADSs or Class A ordinary shares had been sold on the last day of the last taxable year during which we were a PFIC. You are urged to consult your own tax advisor about this election.

In certain circumstances, in lieu of being subject to the special tax rules discussed above, you may make a mark-to-market election with respect to your ADSs or Class A ordinary shares, provided such ADSs or Class A ordinary shares are treated as “marketable stock.” The ADSs or Class A ordinary shares generally will be treated as marketable stock if the ADSs or Class A ordinary shares, as applicable, are “regularly traded” on a “qualified exchange or other market” (each within the meaning of the applicable U.S. Treasury regulations). Under current law, the mark-to-market election may be available to ADS holders as the ADSs are listed on the Nasdaq, which constitutes a qualified exchange, although there can be no assurance that the ADSs will be “regularly traded” for purposes of the mark-to-market election or that the ADSs will continue to be listed on the Nasdaq. The Class A ordinary shares are listed on the Hong Kong Stock Exchange, which must meet certain trading, listing, financial disclosure and other requirements to be treated as a qualified

exchange for these purposes. There also can be no assurance that the Class A ordinary shares will be “ regularly traded” for purposes of the mark-to-market election.

If you make an effective mark-to-market election with respect to our ADSs or Class A ordinary shares, for each taxable year that we are a PFIC you will include as ordinary income the excess of the fair market value of your ADSs or Class A ordinary shares at the end of the year over your adjusted basis in the ADSs or Class A ordinary shares. You will be entitled to deduct as an ordinary loss in each such year the excess of your adjusted basis in the ADSs or Class A ordinary shares over their fair market value at the end of the year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. If you make an effective mark-to-market election, any gain you recognize upon the sale or other disposition of your ADSs or Class A ordinary shares in a year that we are a PFIC will be treated as ordinary income and any loss will be treated as ordinary loss, but such loss will only be treated as ordinary loss to the extent of the net amount previously included in income as a result of the mark-to-market election, and thereafter will be capital loss. If you make an effective mark-to-market election, the general tax rules that apply to distributions by corporations that are not PFICs would apply to distributions by us, except that the reduced rates of taxation for qualified dividend income of non-corporate U.S. holders (as discussed above under “— Taxation of Dividends”) would not be available if we are a PFIC in the taxable year in which the dividends are paid or in the preceding taxable year.

Your adjusted basis in the ADSs or Class A ordinary shares will be increased by the amount of any income inclusion and decreased by the amount of any deductions under the mark-to-market rules. If you make a mark-to-market election, it will be effective for the taxable year for which the election is made and all subsequent taxable years unless the ADSs or Class A ordinary shares are no longer regularly traded on a qualified exchange or other market, or the IRS consents to the revocation of the election. You are urged to consult your tax advisor about the availability of the mark-to-market election, and whether making the election would be advisable in your particular circumstances.

A different election, known as the “qualified electing fund,” or “QEF” election, is generally available to holders of PFIC stock, but only if the corporation provide the holders with a “PFIC Annual Information Statement” containing certain information necessary for the election, including the holder’s pro rata share of the corporation’s earnings and profits and net capital gain for each taxable year, computed according to U.S. federal income tax principles. We do not intend, however, to determine our earnings and profits or net capital gain under U.S. federal income tax principles, nor do we intend to provide U.S. holders with a PFIC Annual Information Statement. Therefore, you should not expect to be eligible to make this election.

If we are a PFIC for any taxable year during which you hold our ADSs or Class A ordinary shares and any of our non-U.S. subsidiaries is also a PFIC or we otherwise have any investment in a non-U.S. company that is treated as an equity interest in a PFIC for U.S. federal income tax purposes (any such non-U.S. subsidiary or non-U.S. company, a “lower-tier PFIC”), you will be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC for purposes of the application of the PFIC rules. Because a mark-to-market election cannot be made for any lower-tier PFICs unless the shares in such lower-tier PFICs are themselves treated as marketable stock, if you make a mark-to-market election with respect to our ADSs or Class A ordinary shares, you may continue to be subject to the special tax rules discussed above (rather than the mark-to-market rules) with respect your indirect interest in any such lower-tier PFIC. You are urged to consult your tax advisors about the application of the PFIC rules to any lower-tier PFIC.

You will generally be required to file IRS Form 8621 if you hold our ADSs or Class A ordinary shares in any year in which we are classified as a PFIC. You are urged to consult your tax advisors concerning the U.S. federal income tax consequences of holding ADSs or Class A ordinary shares if we are considered a PFIC in any taxable year.

Information Reporting and Backup Withholding

In general, information reporting will apply to dividends in respect of our ADSs or Class A ordinary shares and the proceeds from the sale, exchange or other disposition of our ADSs or Class A ordinary shares that are paid to you within the United States (and in certain cases, outside the United States), unless you establish that you are an exempt recipient such as a corporation. A backup withholding tax may apply to such payments if

GDS Holdings Limited

CLASS A ORDINARY SHARES

We may from time to time in one or more offerings offer and sell our Class A ordinary shares, including Class A ordinary shares represented by American depositary shares, or ADSs.

In addition, from time to time, the selling shareholders to be named in a prospectus supplement may offer and sell our Class A ordinary shares or ADSs held by them. The selling shareholders may sell our Class A ordinary shares or ADSs through public or private transactions at prevailing market prices or at privately negotiated prices. We will not receive any proceeds from the sale of our Class A ordinary shares or ADSs by the selling shareholders.

We will provide specific terms of any offering in a supplement to this prospectus. Any prospectus supplement may also add, update, or change information contained in this prospectus. You should carefully read this prospectus and the applicable prospectus supplement as well as the documents incorporated or deemed to be incorporated by reference in this prospectus before you purchase any of the securities offered hereby.

These securities may be offered and sold in the same offering or in separate offerings; to or through underwriters, dealers, and agents; or directly to purchasers. The names of any underwriters, dealers, or agents involved in the sale of our securities, their compensation and any options to purchase additional securities granted to them will be described in the applicable prospectus supplement. For a more complete description of the plan of distribution of these securities, see the section entitled “Plan of Distribution” beginning on page 36 of this prospectus.

The ADSs are listed on the Nasdaq Global Market under the symbol “GDS.” On May 23, 2025, the last reported sale price of the ADSs on the Nasdaq Global Market was US$28.50 per ADS. Our ordinary shares are listed on the Hong Kong Stock Exchange under the stock code “9698.” On May 27, 2025, the last reported trading price of our ordinary shares on the Hong Kong Stock Exchange was HK$27.50 per share.

Our outstanding share capital consists of Class A ordinary shares and Class B ordinary shares. The rights of the holders of our Class A ordinary shares and our Class B ordinary shares are virtually identical other than with respect to voting, conversion and director nomination rights. Each of our Class A and Class B ordinary shares is entitled to one vote per share except that each Class B ordinary share is entitled to 20 votes with respect to (i) the election of a simple majority of our directors and (ii) any change to our Articles of Association that would adversely affect the rights of the holders of Class B ordinary shares at general meetings of our shareholders. Each Class B ordinary share is convertible at any time into one Class A ordinary share. For so long as Mr. William Wei Huang, the founder, chairman of the board, and chief executive officer of our company, continues to have beneficial ownership in not less than 2.75% of the then issued share capital of our company on an as converted basis (subject to certain exclusions), the holders of Class B ordinary shares will also have the right to nominate five directors to our board of directors, which directors shall be subject to the voting arrangements described above. See “Description of Share Capital.”

Investing in these securities involves a high degree of risk. You should carefully consider the risks and uncertainties discussed under the heading “Risk Factors” included in the applicable prospectus supplement or under similar headings in other documents which are incorporated by reference in this prospectus.

GDS Holdings Limited is not an operating company in mainland China, but instead is a Cayman Islands holding company. PRC laws and regulations impose certain restrictions or prohibitions on foreign ownership of companies that engage in telecommunications-related businesses, including the provision of value-added telecommunications services, or VATS. Our internet data center businesses are classified as VATS by the PRC government. Accordingly, we operate substantially all of these business operations in mainland China through the consolidated variable interest entities, or VIEs, and their subsidiaries, as well as through our subsidiaries, and rely on contractual arrangements to control the business operations of the consolidated VIEs. GDS Holdings Limited has no equity ownership in the consolidated VIEs. As used in this prospectus, “GDS,” “our company,” “the Company,” “we,” “our” or “us” refers to GDS Holdings Limited, a company incorporated in the Cayman Islands with limited liability on December 1, 2006 and, where the context requires, its consolidated subsidiaries and the consolidated affiliated entities, including the VIEs and their subsidiaries, from time to time. Investors in the ADSs are not purchasing an equity interest in the consolidated VIEs and their subsidiaries in mainland China, but instead are purchasing an equity interest in a Cayman Islands holding company and its subsidiaries (excluding the VIEs and their subsidiaries).

TABLE OF CONTENTS

uncertainties regarding the interpretation and application of current and future PRC laws, regulations and rules regarding the status of the rights of our Cayman Islands holding company with respect to the contractual arrangements. If our corporate structure or contractual arrangements were found to be in violation of any existing or future PRC laws or regulations, we could be subject to severe penalties, and the relevant regulatory authorities would have discretion in dealing with such violations. As a result, we would be unable to direct the activities of the consolidated VIEs and their subsidiaries, receive their economic benefits and/or claim our contractual control rights over the assets of the VIEs and their subsidiaries that conduct substantially all of our operations in mainland China, we would no longer be able to consolidate such VIEs and their subsidiaries in our consolidated financial statements in accordance with U.S. GAAP, which would likely materially and adversely affect our financial condition and results of operations, and cause the value of our securities to significantly decline or become worthless. For a detailed description of the risks associated with our corporate structure, please refer to risks disclosed under “Item 3. Key Information — D. Risk Factors — Risks Related to Our Corporate Structure” in our annual report on Form 20-F for the fiscal year ended December 31, 2024 (the “2024 Form 20-F”), which is incorporated by reference in this prospectus.

Pursuant to the Holding Foreign Companies Accountable Act, or the HFCA Act, as amended by the Consolidated Appropriations Act, 2023, if we have retained a registered public accounting firm to issue an audit report where the registered public accounting firm has a branch or office that is located in a foreign jurisdiction and the Public Company Accounting Oversight Board, or the PCAOB, has determined that it is unable to inspect or investigate completely because of a position taken by an authority in the foreign jurisdiction, the Securities and Exchange Commission, or the SEC, will identify us as a “covered issuer,” or SEC-identified issuer; and if we were to be identified as an SEC-identified issuer for two consecutive years, the SEC would prohibit our securities (including our shares or ADSs) from being traded on a national securities exchange or in the over-the-counter trading market in the United States. In December 2021, the PCAOB made its determinations, or the 2021 determinations, pursuant to the HFCA Act that it was unable to inspect or investigate completely registered public accounting firms headquartered in mainland China or Hong Kong, including our auditor. In December 2022, the PCAOB vacated the previous 2021 determinations, and as a result, our auditor is no longer a registered public accounting firm that the PCAOB is unable to inspect or investigate completely as of the date of our 2024 Form 20-F or at the time of issuance of the audit report included therein. As such, we do not expect to be identified as an SEC-identified issuer following the filing of our 2024 Form 20-F. However, the PCAOB may change its determinations under the HFCA Act at any point in the future. In particular, if the PCAOB finds its ability to completely inspect and investigate registered public accounting firms headquartered in mainland China or Hong Kong is obstructed by the PRC authorities in any way in the future, the PCAOB may act immediately to consider the need to issue new determinations consistent with the HFCA Act. We cannot assure you that the PCAOB will always have complete access to inspect and investigate our auditor, or that we will not be identified as an SEC-identified issuer again in the future. If we are identified as an SEC-identified issuer again in the future, we cannot assure you that we will be able to change our auditor or take other remedial measures in a timely manner, and if we were to be identified as an SEC-identified issuer for two consecutive years, we would be delisted from Nasdaq and our securities (including our shares and ADSs) will not be permitted for trading “over-the-counter” either. For more details, see “Item 3. Key Information — D. Risk Factors — Risks Related to Doing Business in the People’s Republic of China — The audit report included in this annual report is prepared by an auditor which the U.S. Public Company Accounting Oversight Board was unable to inspect and investigate completely before 2022 and, as such, our investors had been deprived of the benefits of such inspections in the past, and may be deprived of the benefits of such inspections in the future” and “— If the PCAOB determines that it is unable to inspect or investigate completely our auditor at any point in the future, our ADSs may be prohibited from trading in the United States under the HFCA Act, as amended, and any such trading prohibition on our ADSs or threat thereof may materially and adversely affect the price of our ADSs and value of your investment” in our 2024 Form 20-F.

GDS Holdings Limited is a holding company with no material operations of its own. As a result, although other means are available for us to obtain financing at the holding company level, our company’s ability to pay dividends to the shareholders and to service any debt it may incur may depend upon dividends paid by our subsidiaries. Under PRC laws and regulations, our subsidiaries and the VIEs and their subsidiaries incorporated in mainland China are subject to certain restrictions with respect to paying dividends or otherwise transferring any of their net assets to us. Remittance of dividends by a wholly foreign-owned enterprise out of mainland China is also subject to examination by the banks designated by the State Administration of Foreign Exchange of the PRC. In addition, under PRC laws, GDS Holdings Limited may provide funding to our mainland China subsidiaries only through capital contributions or intercompany loans, and to our VIEs and their subsidiaries only through intercompany loans, subject to satisfaction of applicable government registration and approval requirements. For a detailed description of how cash is transferred through our organization, see “Item 3. Key Information — Cash Flows through our Organization” in our 2024 Form 20-F.

OUR COMPANY

We have a 24-year track record of service delivery, successfully fulfilling the requirements of some of the largest and most demanding customers for outsourced data center services. As of December 31, 2024, we had an aggregate net floor area of 613,583 sqm in service, 91.9% of which was committed by customers, and an aggregate net floor area of 102,691 sqm under construction, 64.1% of which was pre-committed by customers.

global technology companies, with many of which we have existing customer relationships. In order to better serve our customers’ requirements, we established DayOne in 2022, with its corporate headquarters in Singapore and its own dedicated management. In order to optimize performance, DayOne has transitioned within a short period of time to become independent of GDS with a strong and diversified shareholder base consisting of leading global investors. Following the closing of DayOne’s Series B equity financing on December 31, 2024, we owned approximately 35.6% of the equity interest of DayOne in the form of ordinary shares on an as-converted basis, and therefore no longer consolidate DayOne for accounting purposes.

From its inception, DayOne focused on creating a new global data center hub known as SIJORI, which integrates Singapore, Johor in Malaysia, and the Riau Islands in Indonesia. Building on its success in SIJORI, DayOne is entering the Tokyo and Greater Bangkok markets with new developments. DayOne also has a presence in Hong Kong. As of December 31, 2024, DayOne had total power committed of 469 MW, power capacity in service of 132 MW, power capacity under construction of 369 MW, and power utilized of 123 MW.

From our inception, we have built up our own in-house data center design capability, which we believe is unparalleled in the industry. We were one of the first movers in developing high-performance data centers in mainland China, anticipating the trend for IT to become increasingly mission-critical, and then in combining high availability with larger net floor area and power capacity to meet the unprecedented requirements of hyperscale cloud service providers and large internet companies. Our data centers are largescale, highly reliable and highly efficient facilities that provide a flexible, modular and secure operating environment in which our customers can house, power and cool the computer systems and networking equipment that support their mission-critical IT. We install high power density (which refers to the ratio of power capacity to net floor area) and optimize power usage efficiency, which enables our customers to deploy their IT systems more efficiently and reduce their operating and capital costs. As a result of our advanced data center design, high technical specifications and robust operating procedures, we are able to make service level commitments related to service availability and other key metrics that meet our customers’ required standards. Within our data centers, we have also developed an innovative service platform to assist our enterprise customers to integrate and control every aspect of their hybrid cloud computing environment across their private servers and one or more public cloud service providers. As of December 31, 2024, we served 926 customers, including PRC and global hyperscale cloud service providers and large internet companies, a diverse community of financial institutions, telecommunications carriers and IT service providers and large domestic private sector and multinational corporations, many of which are leaders in their respective industries. We host the largest public cloud platforms operating in mainland China, some of which are present in multiple GDS data centers. Agreements with our hyperscale cloud service provider and large internet customers generally have terms of three to ten years, while agreements with our financial institution and enterprise customers typically have terms of one to five years.

Registered Office, Entry Number and Objects

Board of Directors

See “Item 6. Directors, Senior Management and Employees — C. Board Practices — Duties of Directors” and “— Appointment, Nomination and Terms of Directors” in our 2024 Form 20-F, which is incorporated by reference in this prospectus.

Ordinary Shares

General. All of our outstanding ordinary shares are fully paid and non-assessable (which means that no further sums are required to be paid by the holders thereof in connection with the issue thereof). Certificates representing the ordinary shares are issued in registered form. Our shareholders who are non-residents of the Cayman Islands may freely hold and vote their ordinary shares.

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors subject to the Companies Act and to the Articles of Association.

Voting Rights.

Class A ordinary shares and Class B ordinary shares carry equal rights, generally rank pari passu with one another and are entitled to one vote per share at general meetings of shareholders, except for only the following matters at general meetings of shareholders, with respect to which Class B ordinary shares are entitled to 20 votes per share: (i) the election of a simple majority of our directors; and (ii) any change to our Articles of Association that would adversely affect the rights of Class B shareholders. Class B ordinary shares are convertible into Class A ordinary shares, and will automatically convert into Class A ordinary shares under certain circumstances. Any Class A ordinary shares which Mr. William Wei Huang, our founder, chairman and chief executive officer, directly or indirectly acquires will be converted into Class B ordinary shares.

TABLE OF CONTENTS

Voting at any meeting of shareholders is by way of a poll, unless the chairman allows a vote by show of hands on a resolution which relates purely to a procedural or administrative matter. Procedural and administrative matters are those that are not on the agenda of the general meeting and relate to the chairman’s duties to maintain the orderly conduct of the meeting or allow the business of the meeting to be properly and effectively dealt with, while affording all shareholders a reasonable opportunity to express their views.

Pursuant to our Articles of Association the following matters will be subject to ordinary resolution of the shareholders, with Class A ordinary shares and Class B ordinary shares each being entitled to one vote per share: (i) the election of two independent directors nominated by our nominating and corporate governance committee; (ii) any allotment or issuance of any of our shares or securities (in any 12-month period, whether in a single transaction or a series of transactions) equal to 10% or more of our share capital, or 10% or more of our voting power, prior to such allotment or issuance (without regard to any exemption from shareholder approval available under the Nasdaq Stock Market Rules); and (iii) any disposition of all, or 10% or more, of our undertakings or assets, as defined in our Articles of Association.

Subject to the abovementioned matters at general meetings of shareholders with respect to which Class B ordinary shares are entitled to 20 votes per share, an ordinary resolution to be passed by the shareholders requires the affirmative vote of a simple majority of votes attached to the ordinary shares cast in a general meeting, while a special resolution requires the affirmative vote of no less than 75% of votes cast attached to the ordinary shares. A special resolution will be required for important matters such as a change of name or making changes to our Memorandum and Articles of Association.

Conversion. Class B ordinary shares are convertible into Class A ordinary shares. All Class B ordinary shares are subject to automatic conversion into Class A ordinary shares on the same business day as the first to occur of the following: (i) Mr. William Wei Huang ceasing to have beneficial ownership (as such term is interpreted pursuant to applicable U.S. securities laws and rules, regulations and forms promulgated thereunder by the SEC), in aggregate, of not less than two point seventy-five per cent (2.75%) of our issued and outstanding share capital on an as-converted basis; (ii) the Foreign Investment Law in the form implemented does not require that our VIE entities as it relates to VIE entities be owned or controlled by PRC nationals or entities; (iii) the PRC law no longer requires the conduct of the businesses carried out, or contemplated to be carried out, by us in the PRC, be owned or controlled by PRC nationals or entities; (iv) the promulgation of the Foreign Investment Law as it relates to VIE entities is abandoned by the relevant authorities in the PRC; or (v) the relevant authorities in the PRC approve our VIE structure without the need for our VIE entities to be controlled by PRC nationals or entities; provided, however, that the Class B ordinary shares shall not be automatically converted upon ceasing to constitute two point seventy-five per cent (2.75%) of our issued and outstanding share capital on an as-converted basis if 75% of the board of directors resolve that such automatic conversion shall, in their opinion, result in our failing to comply with any applicable foreign ownership restrictions under PRC law. Class B shareholders may elect to convert any or all of their Class B ordinary shares into Class A ordinary shares. Each Class B ordinary share is generally convertible into one Class A ordinary share, or at a conversion rate of 1:1. However, if and when the nominal amount of one Class A ordinary share changes by reason of consolidation or sub-division, the applicable conversion rate of Class B ordinary shares into Class A ordinary shares shall equal the quotient of the revised nominal amount, divided by the former nominal amount, of one Class A ordinary share.

Transfer of Ordinary Shares.

TABLE OF CONTENTS

•

the instrument of transfer is in respect of only one class of ordinary shares;

•

the instrument of transfer is properly stamped, if required;

•

the ordinary shares transferred are fully paid and free of any lien in favor of us; and

•

any fee related to the transfer has been paid to us; and

•

the transfer is not to more than four joint holders.

Variations of Rights of Shares

If at any time, our share capital is divided into different classes of shares, all or any of the special rights attached to any class of shares may, subject to the provisions of the Companies Act, be varied with the sanction of a special resolution passed at a general meeting of the holders of the shares of that class. Consequently, the rights of any class of shares cannot be detrimentally altered without a majority of 75% of the votes cast of all of the shares in that class at a general meeting of the holders of the shares of that class. The rights conferred upon the holders of the shares of any class issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu with such existing class of shares

General Meetings of Shareholders

TABLE OF CONTENTS

or any one or more shareholders holding at the date of deposit of the requisition not less than 10% of the voting rights, on a one vote per share basis, in the share capital of the Company, to requisition an extraordinary general meeting of our shareholders, in which case our directors are obliged to call such meeting and to put the resolutions so requisitioned to a vote at such meeting; however, our Memorandum and Articles of Association do not provide our shareholders with any right to put any proposals before annual general meetings or extraordinary general meetings not requisitioned by such shareholders. When STT Garnet no longer has any director appointment right as described herein, STT Garnet will be eligible for the same right to requisition a shareholder meeting described above on the same terms as other Class A ordinary shareholders, where the one-third of the Class A ordinary shares will then be calculated based upon all Class A ordinary shares issued and outstanding. STT Garnet and the Class B shareholders also have the right to requisition a general meeting insofar as is necessary to exercise and protect their respective nomination and appointment rights.

Inspection of Books and Records

Holders of our ordinary shares will have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records. However, we will in our Articles provide our shareholders with the right to inspect our list of shareholders and to receive annual audited financial statements. See “Where You Can Find More Information About Us.”

Anti-Takeover Provisions in the Memorandum and Articles of Association.

Changes in Capital

We may from time to time by ordinary resolution:

•

increase the share capital by such sum, to be divided into shares of such classes and amount, as the resolution shall prescribe;

•

consolidate and divide all or any of our share capital into shares of a larger amount than our existing shares;

•

sub-divide our existing shares, or any of them into shares of a smaller amount; or

•

We may by special resolution reduce our share capital or any capital redemption reserve in any manner permitted by law.

Certain Enumerated Rights under Our Articles of Association

•

an exempted company may register as a segregated portfolio company.

TABLE OF CONTENTS

Differences in Corporate Law

The Companies Act is derived, to a large extent, from the older Companies Acts of England but does not follow recent English statutory enactments and accordingly there are significant differences between the Companies Act and the current Companies Act of England. In addition, the Companies Act differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of certain significant differences between the provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in the State of Delaware in the United States and their shareholders.

Mergers and Similar Arrangements.

The consent of each holder of a fixed or floating security interest over a constituent company is required unless this requirement is waived by a court in the Cayman Islands.

•

the statutory provisions as to the required majority vote have been met;

•

the arrangement is such that may be reasonably approved by an intelligent and honest man of that class acting in respect of his interest; and

•

the arrangement is not one that would more properly be sanctioned under some other provision of the Companies Act.

TABLE OF CONTENTS

rights, which would otherwise ordinarily be available to dissenting shareholders of Delaware corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

Shareholders’ Suits.

•

a company acts or proposes to act illegally or ultra vires;

•

the act complained of, although not ultra vires, could only be effected duly if authorized by more than a simple majority vote that has not been obtained; and

•

those who control the company are perpetrating a “fraud on the minority.”

Indemnification of Directors and Executive Officers and Limitation of Liability.

Cayman Islands law does not limit the extent to which a company’s articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. Our Memorandum and Articles of Association permit indemnification of officers and directors for actions, costs, charges, losses, damages and expenses incurred by reason of any act done, concurred in or omitted in or about the execution of their duty, or supposed duty, in their respective offices or trusts provided that the indemnity shall not extend to any matter in respect of any fraud or dishonesty which may attach to such directors or officers. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation. In addition, we have entered into indemnification agreements with our directors and senior executive officers that will provide such persons with additional indemnification beyond that provided in our Memorandum and Articles of Association.

Directors’ Fiduciary Duties.

TABLE OF CONTENTS

in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

with an “interested shareholder” for three years following the date that such person becomes an interested shareholder. An interested shareholder generally is a person or a group who or which owns or owned 15% or more of the target’s outstanding voting stock within the past three years. This has the effect of limiting the ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which such shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware corporation to negotiate the terms of any acquisition transaction with the target’s board of directors.

DESCRIPTION OF AMERICAN DEPOSITARY SHARES

General

JPMorgan Chase Bank, N.A., acts as the depositary for the ADSs. Each ADS represents an ownership interest in eight (8) Class A ordinary shares deposited with the custodian, as agent of the depositary. Each ADS also represents an ownership interest in any other securities, cash or other property which may be held by the depositary. Unless certificated American depositary receipts, or ADRs, are specifically requested by you, all ADSs are issued on the books of our depositary in book-entry form and periodic statements will be mailed to you which reflect your ownership interest in such ADSs. In our description, references to American depositary receipts or ADRs shall include the statements you will receive which reflect your ownership of ADSs.

The depositary’s office is located at JPMorgan Chase Bank, N.A., 383 Madison Avenue, Floor 11, New York, New York 10179.

You may hold ADSs either directly or indirectly through your broker or other financial institution. If you hold ADSs directly, by having an ADS registered in your name on the books of the depositary, you are an ADR holder. This description assumes you hold your ADSs directly. If you hold the ADSs through your broker or financial institution nominee, you must rely on the procedures of such broker or financial institution to assert the rights of an ADR holder described in this section. You should consult with your broker or financial institution to find out what those procedures are.

As an ADR holder, we do not treat you as a shareholder of ours and you do not have any shareholder rights. Cayman Islands law governs shareholder rights. Because the depositary or its nominee is the shareholder of record for the Class A ordinary shares represented by all outstanding ADSs, shareholder rights rest with such record holder. Your rights are those of an ADR holder. Such rights derive from the terms of the deposit agreement entered into among us, the depositary and all registered holders from time to time of ADSs issued under the deposit agreement. The obligations of the depositary and its agents are also set out in the deposit agreement. Because the depositary or its nominee is actually the registered owner of the Class A ordinary shares, you must rely on it to exercise the rights of a shareholder on your behalf. The deposit agreement and the ADSs are governed by New York law. Under the deposit agreement, as an ADR holder, you agree that any legal suit, action or proceeding against or involving us or the depositary, arising out of or based upon the deposit agreement, the ADSs or the transactions contemplated thereby, may only be instituted in a state or federal court in New York, New York, and you irrevocably waive any objection which you may have to the laying of venue of any such proceeding and irrevocably submit to the exclusive jurisdiction of such courts in any such suit, action or proceeding.

The following is a summary of what we believe to be the material terms of the deposit agreement. Notwithstanding this, because it is a summary, it may not contain all the information that you may otherwise deem important. For more complete information, you should read the entire deposit agreement and the form of ADR which contains the terms of your ADSs. You can read a copy of the deposit agreement which is filed as an exhibit to the registration statement of which this prospectus forms a part. You may also obtain a copy of the deposit agreement at the SEC’s Public Reference Room which is located at 100 F Street, NE, Washington, DC 20549. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-732-0330. You may also find the registration statement and the attached deposit agreement on the SEC’s website at http://www.sec.gov.

Share Dividends and Other Distributions

How will I receive dividends and other distributions on the Class A ordinary shares underlying my ADSs?

We may make various types of distributions with respect to our securities. The depositary has agreed that, to the extent practicable, it will pay to you the cash dividends or other distributions it or the custodian receives on shares or other deposited securities, after converting any cash received into U.S. dollars (if it determines such conversion may be made on a reasonable basis) and, in all cases, making any necessary deductions provided for in the deposit agreement. The depositary may utilize a division, branch or affiliate of JPMorgan Chase Bank, N.A. to direct, manage and/or execute any public and/or private sale of securities under the deposit agreement. Such division, branch and/or affiliate may charge the depositary a fee in connection with such

TABLE OF CONTENTS

sales, which fee is considered an expense of the depositary. You will receive these distributions in proportion to the number of underlying securities that your ADSs represent.

Except as stated below, the depositary will deliver such distributions to ADR holders in proportion to their interests in the following manner:

•

Cash. The depositary will distribute any U.S. dollars available to it resulting from a cash dividend or other cash distribution or the net proceeds of sales of any other distribution or portion thereof (to the extent applicable), on an averaged or other practicable basis, subject to (i) appropriate adjustments for taxes withheld, (ii) such distribution being impermissible or impracticable with respect to certain registered ADR holders, and (iii) deduction of the depositary’s and/or its agents’ expenses in (1) converting any foreign currency to U.S. dollars to the extent that it determines that such conversion may be made on a reasonable basis, (2) transferring foreign currency or U.S. dollars to the United States by such means as the depositary may determine to the extent that it determines that such transfer may be made on a reasonable basis, (3) obtaining any approval or license of any governmental authority required for such conversion or transfer, which is obtainable at a reasonable cost and within a reasonable time and (4) making any sale by public or private means in any commercially reasonable manner. If exchange rates fluctuate during a time when the depositary cannot convert a foreign currency, you may lose some or all of the value of the distribution.

•

Shares. In the case of a distribution in shares, the depositary will issue additional ADRs to evidence the number of ADSs representing such Class A ordinary shares. Only whole ADSs will be issued. Any shares which would result in fractional ADSs will be sold and the net proceeds will be distributed in the same manner as cash to the ADR holders entitled thereto.

•

Rights to receive additional shares. In the case of a distribution of rights to subscribe for additional shares or other rights, if we timely provide evidence satisfactory to the depositary that it may lawfully distribute such rights, the depositary will distribute warrants or other instruments in the discretion of the depositary representing such rights. However, if we do not timely furnish such evidence, the depositary may:

(i) sell such rights if practicable and distribute the net proceeds in the same manner as cash to the ADR holders entitled thereto; or

(ii) if it is not practicable to sell such rights by reason of the non-transferability of the rights, limited markets therefor, their short duration or otherwise, do nothing and allow such rights to lapse, in which case ADR holders will receive nothing and the rights may lapse.

•

Other Distributions. In the case of a distribution of securities or property other than those described above, the depositary may either (i) distribute such securities or property in any manner it deems equitable and practicable or (ii) to the extent the depositary deems distribution of such securities or property not to be equitable and practicable, sell such securities or property and distribute any net proceeds in the same way it distributes cash.

If the depositary determines in its discretion that any distribution described above is not practicable with respect to any specific registered ADR holder, the depositary may choose any method of distribution that it deems practicable for such ADR holder, including the distribution of foreign currency, securities or property, or it may retain such items, without paying interest on or investing them, on behalf of the ADR holder as deposited securities, in which case the ADSs will also represent the retained items.

Any U.S. dollars will be distributed by checks drawn on a bank in the United States for whole dollars and cents. Fractional cents will be withheld without liability and dealt with by the depositary in accordance with its then current practices.

The depositary is not responsible if it fails to determine that any distribution or action is lawful or reasonably practicable.

There can be no assurance that the depositary will be able to convert any currency at a specified exchange rate or sell any property, rights, shares or other securities at a specified price, nor that any of such transactions can be completed within a specified time period. All purchases and sales of securities will be handled by the Depositary in accordance with its then current policies, which are currently set forth in the “Depositary Receipt Sale and

TABLE OF CONTENTS

Purchase of Security” section of https://www.adr.com/Investors/FindOutAboutDRs, the location and contents of which the Depositary shall be solely responsible for.

Deposit, Withdrawal and Cancellation

How does the depositary issue ADSs?

The depositary will issue ADSs if you or your broker deposit Class A ordinary shares or evidence of rights to receive Class A ordinary shares with the custodian and pay the fees and expenses owing to the depositary in connection with such issuance. In the case of the ADSs to be issued under this prospectus, we will arrange with the underwriters named herein to deposit such Class A ordinary shares.

Class A ordinary shares deposited in the future with the custodian must be accompanied by certain delivery documentation and shall, at the time of such deposit, be registered in the name of JPMorgan Chase Bank, N.A., as depositary for the benefit of holders of ADRs or in such other name as the depositary shall direct.

The custodian will hold all deposited shares (including those being deposited by or on our behalf in connection with the offering to which this prospectus relates) for the account and to the order of the depositary. ADR holders thus have no direct ownership interest in the Class A ordinary shares and only have such rights as are contained in the deposit agreement. The custodian will also hold any additional securities, property and cash received on or in substitution for the deposited Class A ordinary shares. The deposited Class A ordinary shares and any such additional items are referred to as “deposited securities”.

Upon each deposit of Class A ordinary shares, receipt of related delivery documentation and compliance with the other provisions of the deposit agreement, including the payment of the fees and charges of the depositary and any taxes or other fees or charges owing, the depositary will issue an ADR or ADRs in the name or upon the order of the person entitled thereto evidencing the number of ADSs to which such person is entitled. All of the ADSs issued will, unless specifically requested to the contrary, be part of the depositary’s direct registration system, and a registered holder will receive periodic statements from the depositary which will show the number of ADSs registered in such holder’s name. An ADR holder can request that the ADSs not be held through the depositary’s direct registration system and that a certificated ADR be issued.

How do ADR holders cancel an ADS and obtain deposited securities?

When you turn in your ADR certificate at the depositary’s office, or when you provide proper instructions and documentation in the case of direct registration ADSs, the depositary will, upon payment of certain applicable fees, charges and taxes, deliver the underlying Class A ordinary shares to you or upon your written order. Delivery of deposited securities in certificated form will be made at the custodian’s office. At your risk, expense and request, the depositary may deliver deposited securities at such other place as you may request.

The depositary may only restrict the withdrawal of deposited securities in connection with:

•

temporary delays caused by closing our transfer books or those of the depositary or the deposit of Class A ordinary shares in connection with voting at a shareholders’ meeting, or the payment of dividends;

•

the payment of fees, taxes and similar charges; or

•

compliance with any U.S. or foreign laws or governmental regulations relating to the ADRs or to the withdrawal of deposited securities.

This right of withdrawal may not be limited by any other provision of the deposit agreement.

Record Dates

The depositary may, after consultation with us if practicable, fix record dates for the determination of the registered ADR holders who will be entitled (or obligated, as the case may be):

•

to receive any distribution on or in respect of shares,

•

to give instructions for the exercise of voting rights at a meeting of holders of shares,

TABLE OF CONTENTS

•

to pay the fee assessed by the depositary for administration of the ADR program and for any expenses as provided for in the ADR, or

•

to receive any notice or to act in respect of other matters,

all subject to the provisions of the deposit agreement.

Voting Rights

How do I vote?

If you are an ADR holder and the depositary asks you to provide it with voting instructions, you may instruct the depositary how to exercise the voting rights for the Class A ordinary shares which underlie your ADSs. Subject to the next sentence, as soon as practicable after receipt from us of notice of any meeting at which the holders of shares are entitled to vote, or of our solicitation of consents or proxies from holders of shares, the depositary shall fix the ADS record date in accordance with the provisions of the deposit agreement in respect of such meeting or solicitation of consent or proxy. The depositary shall, if we request in writing in a timely manner (the depositary having no obligation to take any further action if our request shall not have been received by the depositary at least 30 days prior to the date of such vote or meeting) and at our expense and provided no legal prohibitions exist, distribute to the registered ADR holders a notice stating such information as is contained in the voting materials received by the depositary and describing how you may instruct the depositary to exercise the voting rights for the Class A ordinary shares which underlie your ADSs, including instructions for giving a discretionary proxy to a person designated by us. For instructions to be valid, the depositary must receive them in the manner and on or before the date specified. The depositary will try, as far as is practical, subject to the provisions of and governing the underlying Class A ordinary shares or other deposited securities, to vote or to have its agents vote the Class A ordinary shares or other deposited securities as you instruct. The depositary will only vote or attempt to vote as you instruct. Holders are strongly encouraged to forward their voting instructions to the depositary as soon as possible. Voting instructions will not be deemed to be received until such time as the ADR department responsible for proxies and voting has received such instructions notwithstanding that such instructions may have been physically received by the depositary prior to such time. The depositary will not itself exercise any voting discretion. Furthermore, neither the depositary nor its agents are responsible for any failure to carry out any voting instructions, for the manner in which any vote is cast or for the effect of any vote. Notwithstanding anything contained in the deposit agreement or any ADR, the depositary may, to the extent not prohibited by law or regulations, or by the requirements of the stock exchange on which the ADSs are listed, in lieu of distribution of the materials provided to the depositary in connection with any meeting of, or solicitation of consents or proxies from, holders of deposited securities, distribute to the registered holders of ADRs a notice that provides such holders with, or otherwise publicizes to such holders, instructions on how to retrieve such materials or receive such materials upon request (i.e., by reference to a website containing the materials for retrieval or a contact for requesting copies of the materials).

We have advised the depositary that under the Cayman Islands law and our constituent documents, each as in effect as of the date of the deposit agreement, voting at any meeting of shareholders is by show of hands unless a poll is (before or on the declaration of the results of the show of hands) demanded. In the event that voting on any resolution or matter is conducted on a show of hands basis in accordance with our constituent documents, the depositary will refrain from voting and the voting instructions received by the depositary from holders shall lapse. The depositary will not demand a poll or join in demanding a poll, whether or not requested to do so by holders of ADSs. There is no guarantee that you will receive voting materials in time to instruct the depositary to vote and it is possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote.

Reports and Other Communications

Will ADR holders be able to view our reports?

The depositary will make available for inspection by ADR holders at the offices of the depositary and the custodian the deposit agreement, the provisions of or governing deposited securities, and any written

TABLE OF CONTENTS

communications from us which are both received by the custodian or its nominee as a holder of deposited securities and made generally available to the holders of deposited securities.

Additionally, if we make any written communications generally available to holders of our Class A ordinary shares, and we furnish copies thereof (or English translations or summaries) to the depositary, it will distribute the same to registered ADR holders.

Fees and Expenses

The depositary may charge each person to whom ADSs are issued, including, without limitation, issuances against deposits of Class A ordinary shares, issuances in respect of share distributions, rights and other distributions, issuances pursuant to a stock dividend or stock split declared by us or issuances pursuant to a merger, exchange of securities or any other transaction or event affecting the ADSs or deposited securities, and each person surrendering ADSs for withdrawal of deposited securities or whose ADRs are cancelled or reduced for any other reason, $5.00 for each 100 ADSs (or any portion thereof) issued, delivered, reduced, cancelled or surrendered, as the case may be. The depositary may sell (by public or private sale) sufficient securities and property received in respect of a share distribution, rights and/or other distribution prior to such deposit to pay such charge.

The following additional charges shall be incurred by the ADR holders, by any party depositing or withdrawing Class A ordinary shares or by any party surrendering ADSs and/or to whom ADSs are issued (including, without limitation, issuance pursuant to a stock dividend or stock split declared by us or an exchange of stock regarding the ADSs or the deposited securities or a distribution of ADSs), whichever is applicable:

•

a fee of U.S.$1.50 per ADR or ADRs for transfers of certificated or direct registration ADRs;

•

a fee of up to U.S.$0.05 per ADS for any cash distribution made pursuant to the deposit agreement;

•

an aggregate fee of up to U.S.$0.05 per ADS per calendar year (or portion thereof) for services performed by the depositary in administering the ADRs (which fee may be charged on a periodic basis during each calendar year and shall be assessed against holders of ADRs as of the record date or record dates set by the depositary during each calendar year and shall be payable in the manner described in the next succeeding provision);

•

a fee for the reimbursement of such fees, charges and expenses as are incurred by the depositary and/or any of its agents (including, without limitation, the custodian and expenses incurred on behalf of holders in connection with compliance with foreign exchange control regulations or any law or regulation relating to foreign investment) in connection with the servicing of the Class A ordinary shares or other deposited securities, the sale of securities (including, without limitation, deposited securities), the delivery of deposited securities or otherwise in connection with the depositary’s or its custodian’s compliance with applicable law, rule or regulation (which fees and charges shall be assessed on a proportionate basis against holders as of the record date or dates set by the depositary and shall be payable at the sole discretion of the depositary by billing such holders or by deducting such charge from one or more cash dividends or other cash distributions);

•

a fee for the distribution of securities (or the sale of securities in connection with a distribution), such fee being in an amount equal to the $0.05 per ADS issuance fee for the execution and delivery of ADSs which would have been charged as a result of the deposit of such securities (treating all such securities as if they were shares) but which securities or the net cash proceeds from the sale thereof are instead distributed by the depositary to those holders entitled thereto;

•

stock transfer or other taxes and other governmental charges;

•

cable, telex and facsimile transmission and delivery charges incurred at your request in connection with the deposit or delivery of Class A ordinary shares, ADRs or deposited securities;

•

transfer or registration fees for the registration of transfer of deposited securities on any applicable register in connection with the deposit or withdrawal of deposited securities;

TABLE OF CONTENTS

•

in connection with the conversion of foreign currency into U.S. dollars, JPMorgan Chase Bank, N.A. shall deduct out of such foreign currency the fees, expenses and other charges charged by it and/or its agent (which may be a division, branch or affiliate) so appointed in connection with such conversion; and

•

fees of any division, branch or affiliate of the depositary utilized by the depositary to direct, manage and/or execute any public and/or private sale of securities under the deposit agreement.

JPMorgan Chase Bank, N.A. and/or its agent may act as principal for such conversion of foreign currency. For further details see https://www.adr.com.

We will pay all other charges and expenses of the depositary and any agent of the depositary (except the custodian) pursuant to agreements from time to time between us and the depositary. The charges described above may be amended from time to time by agreement between us and the depositary.

The depositary may make available to us a set amount or a portion of the depositary fees charged in respect of the ADR program or otherwise upon such terms and conditions as we and the depositary may agree from time to time. The depositary collects its fees for issuance and cancellation of ADSs directly from investors depositing Class A ordinary shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions, or by directly billing investors, or by charging the book-entry system accounts of participants acting for them. The depositary will generally set off the amounts owing from distributions made to holders of ADSs. If, however, no distribution exists and payment owing is not timely received by the depositary, the depositary may refuse to provide any further services to holders that have not paid those fees and expenses owing until such fees and expenses have been paid. At the discretion of the depositary, all fees and charges owing under the deposit agreement are due in advance and/or when declared owing by the depositary.

Payment of Taxes

If any taxes or other governmental charges (including any penalties and/or interest) shall become payable by or on behalf of the custodian or the depositary with respect to any ADR, any deposited securities represented by the ADSs evidenced thereby or any distribution thereon, including, without limitation, any Chinese Enterprise Income Tax owing if the Circular Guoshuifa [2009] No. 82 issued by the Chinese State Administration of Taxation (SAT) or any other circular, edict, order or ruling, as issued and as from time to time amended, is applied or otherwise, such tax or other governmental charge shall be paid by the holder thereof to the depositary and by holding or having held an ADR the holder and all prior holders thereof, jointly and severally, agree to indemnify, defend and save harmless each of the depositary and its agents in respect thereof. If an ADR holder owes any tax or other governmental charge, the depositary may (i) deduct the amount thereof from any cash distributions, or (ii) sell deposited securities (by public or private sale) and deduct the amount owing from the net proceeds of such sale. In either case the ADR holder remains liable for any shortfall. If any tax or governmental charge is unpaid, the depositary may also refuse to effect any registration, registration of transfer, split-up or combination of deposited securities or withdrawal of deposited securities until such payment is made. If any tax or governmental charge is required to be withheld on any cash distribution, the depositary may deduct the amount required to be withheld from any cash distribution or, in the case of a non-cash distribution, sell the distributed property or securities (by public or private sale) in such amounts and in such manner as the depositary deems necessary and practicable to pay such taxes and distribute any remaining net proceeds or the balance of any such property after deduction of such taxes to the ADR holders entitled thereto.

By holding an ADR or an interest therein, you will be agreeing to indemnify us, the depositary, its custodian and any of our or their respective officers, directors, employees, agents and affiliates against, and hold each of them harmless from, any claims by any governmental authority with respect to taxes, additions to tax, penalties or interest arising out of any refund of taxes, reduced rate of withholding at source or other tax benefit obtained.

Reclassifications, Recapitalizations and Mergers

If we take certain actions that affect the deposited securities, including (i) any change in par value, split-up, consolidation, cancellation or other reclassification of deposited securities or (ii) any distributions of shares

TABLE OF CONTENTS

or other property not made to holders of ADRs or (iii) any recapitalization, reorganization, merger, consolidation, liquidation, receivership, bankruptcy or sale of all or substantially all of our assets, then the depositary may choose to, and shall if reasonably requested by us:

(1)

amend the form of ADR;

(2)

distribute additional or amended ADRs;

(3)

distribute cash, securities or other property it has received in connection with such actions;

(4)

sell any securities or property received and distribute the proceeds as cash; or

(5)

none of the above.

If the depositary does not choose any of the above options, any of the cash, securities or other property it receives will constitute part of the deposited securities and each ADS will then represent a proportionate interest in such property.

Amendment and Termination

How may the deposit agreement be amended?

We may agree with the depositary to amend the deposit agreement and the ADSs without your consent for any reason. ADR holders must be given at least 30 days’ notice of any amendment that imposes or increases any fees or charges (other than stock transfer or other taxes and other governmental charges, transfer or registration fees, SWIFT, cable, telex or facsimile transmission costs, delivery costs or other such expenses), or otherwise prejudices any substantial existing right of ADR holders. Such notice need not describe in detail the specific amendments effectuated thereby, but must identify to ADR holders a means to access the text of such amendment. If an ADR holder continues to hold an ADR or ADRs after being so notified, such ADR holder is deemed to agree to such amendment and to be bound by the deposit agreement as so amended. Notwithstanding the foregoing, if any governmental body or regulatory body should adopt new laws, rules or regulations which would require amendment or supplement of the deposit agreement or the form of ADR to ensure compliance therewith, we and the depositary may amend or supplement the deposit agreement and the ADR at any time in accordance with such changed laws, rules or regulations, which amendment or supplement may take effect before a notice is given or within any other period of time as required for compliance. No amendment, however, will impair your right to surrender your ADSs and receive the underlying securities, except in order to comply with mandatory provisions of applicable law.

How may the deposit agreement be terminated?

The depositary may, and shall at our written direction, terminate the deposit agreement and the ADRs by mailing notice of such termination to the registered holders of ADRs at least 30 days prior to the date fixed in such notice for such termination; provided, however, if the depositary shall have (i) resigned as depositary under the deposit agreement, notice of such termination by the depositary shall not be provided to registered holders unless a successor depositary shall not be operating under the deposit agreement within 60 days of the date of such resignation, and (ii) been removed as depositary under the deposit agreement, notice of such termination by the depositary shall not be provided to registered holders of ADRs unless a successor depositary shall not be operating under the deposit agreement on the 120th day after our notice of removal was first provided to the depositary. After the date so fixed for termination, (a) all direct registration ADRs shall cease to be eligible for the direct registration system and shall be considered ADRs issued on the ADR register maintained by the depositary and (b) the depositary shall use its reasonable efforts to ensure that the ADSs cease to be DTC eligible so that neither DTC nor any of its nominees shall thereafter be a registered holder of ADRs. At such time as the ADSs cease to be DTC eligible and/or neither DTC nor any of its nominees is a registered holder of ADRs, the depositary shall (a) instruct its custodian to deliver all Class A ordinary shares to us along with a general stock power that refers to the names set forth on the ADR register maintained by the depositary and (b) provide us with a copy of the ADR register maintained by the depositary. Upon receipt of such Class A ordinary shares and the ADR register maintained by the depositary, we have agreed to use our best efforts to issue to each registered holder a Share certificate representing the Shares represented by the ADSs reflected on the ADR register maintained by the depositary in such registered

TABLE OF CONTENTS

holder’s name and to deliver such Share certificate to the registered holder at the address set forth on the ADR register maintained by the depositary. After providing such instruction to the custodian and delivering a copy of the ADR register to us, the depositary and its agents will perform no further acts under the deposit agreement or the ADRs and shall cease to have any obligations under the deposit agreement and/or the ADRs.

Limitations on Obligations and Liability to ADR Holders

Limits on our obligations and the obligations of the depositary; limits on liability to ADR holders and holders of ADSs

Prior to the issue, registration, registration of transfer, split-up, combination, or cancellation of any ADRs, or the delivery of any distribution in respect thereof, and from time to time in the case of the production of proofs as described below, we or the depositary or its custodian may require:

•

payment with respect thereto of (i) any stock transfer or other tax or other governmental charge, (ii) any stock transfer or registration fees in effect for the registration of transfers of Class A ordinary shares or other deposited securities upon any applicable register and (iii) any applicable fees and expenses described in the deposit agreement;

•

the production of proof satisfactory to it of (i) the identity of any signatory and genuineness of any signature and (ii) such other information, including without limitation, information as to citizenship, residence, exchange control approval, beneficial ownership of any securities, compliance with applicable law, regulations, provisions of or governing deposited securities and terms of the deposit agreement and the ADRs, as it may deem necessary or proper; and

•

compliance with such regulations as the depositary may establish consistent with the deposit agreement.

The issuance of ADRs, the acceptance of deposits of Class A ordinary shares, the registration, registration of transfer, split-up or combination of ADRs or the withdrawal of Class A ordinary shares, may be suspended, generally or in particular instances, when the ADR register or any register for deposited securities is closed or when any such action is deemed advisable by the depositary; provided that the ability to withdraw Class A ordinary shares may only be limited under the following circumstances: (i) temporary delays caused by closing transfer books of the depositary or our transfer books or the deposit of Class A ordinary shares in connection with voting at a shareholders’ meeting, or the payment of dividends, (ii) the payment of fees, taxes, and similar charges, and (iii) compliance with any laws or governmental regulations relating to ADRs or to the withdrawal of deposited securities.

The deposit agreement expressly limits the obligations and liability of the depositary, ourselves and our respective agents, provided, however, that no disclaimer of liability under the Securities Act is intended by any of the limitations of liabilities provisions of the deposit agreement. In the deposit agreement it provides that neither we nor the depositary nor any such agent will be liable if:

•

any present or future law, rule, regulation, fiat, order or decree of the United States, the Cayman Islands, the People’s Republic of China (including the Hong Kong Special Administrative Region, the People’s Republic of China) or any other country or jurisdiction, or of any governmental or regulatory authority or securities exchange or market or automated quotation system, the provisions of or governing any deposited securities, any present or future provision of our charter, any act of God, war, terrorism, nationalization, expropriation, currency restrictions, work stoppage, strike, civil unrest, revolutions, rebellions, explosions, computer failure or circumstance beyond our, the depositary’s or our respective agents’ direct and immediate control shall prevent or delay, or shall cause any of them to be subject to any civil or criminal penalty in connection with, any act which the deposit agreement or the ADRs provide shall be done or performed by us, the depositary or our respective agents (including, without limitation, voting);

•

it exercises or fails to exercise discretion under the deposit agreement or the ADRs including, without limitation, any failure to determine that any distribution or action may be lawful or reasonably practicable;

•

it performs its obligations under the deposit agreement and ADRs without gross negligence or willful misconduct;

•

it takes any action or refrains from taking any action in reliance upon the advice of or information from legal counsel, accountants, any person presenting Class A ordinary shares for deposit, any registered holder of ADRs, or any other person believed by it to be competent to give such advice or information; or

TABLE OF CONTENTS

•

it relies upon any written notice, request, direction, instruction or document believed by it to be genuine and to have been signed, presented or given by the proper party or parties.

Neither the depositary nor its agents have any obligation to appear in, prosecute or defend any action, suit or other proceeding in respect of any deposited securities or the ADRs. We and our agents shall only be obligated to appear in, prosecute or defend any action, suit or other proceeding in respect of any deposited securities or the ADRs, which in our opinion may involve us in expense or liability, if indemnity satisfactory to us against all expense (including fees and disbursements of counsel) and liability is furnished as often as may be required. The depositary and its agents may fully respond to any and all demands or requests for information maintained by or on its behalf in connection with the deposit agreement, any registered holder or holders of ADRs, any ADRs or otherwise related to the deposit agreement or ADRs to the extent such information is requested or required by or pursuant to any lawful authority, including without limitation laws, rules, regulations, administrative or judicial process, banking, securities or other regulators. The depositary shall not be liable for the acts or omissions made by, or the insolvency of, any securities depository, clearing agency or settlement system. Furthermore, the depositary shall not be responsible for, and shall incur no liability in connection with or arising from, the insolvency of any custodian that is not a branch or affiliate of JPMorgan Chase Bank, N.A. Notwithstanding anything to the contrary contained in the deposit agreement or any ADRs, the depositary shall not be responsible for, and shall incur no liability in connection with or arising from, any act or omission to act on the part of the custodian except to the extent that the custodian has (i) committed fraud or willful misconduct in the provision of custodial services to the depositary or (ii) failed to use reasonable care in the provision of custodial services to the depositary as determined in accordance with the standards prevailing in the jurisdiction in which the custodian is located. The depositary and the custodian(s) may use third party delivery services and providers of information regarding matters such as pricing, proxy voting, corporate actions, class action litigation and other services in connection with the ADRs and the deposit agreement, and use local agents to provide extraordinary services such as attendance at annual meetings of issuers of securities. Although the depositary and the custodian will use reasonable care (and cause their agents to use reasonable care) in the selection and retention of such third party providers and local agents, they will not be responsible for any errors or omissions made by them in providing the relevant information or services. The depositary shall not have any liability for the price received in connection with any sale of securities, the timing thereof or any delay in action or omission to act nor shall it be responsible for any error or delay in action, omission to act, default or negligence on the part of the party so retained in connection with any such sale or proposed sale.

The depositary has no obligation to inform ADR holders or other holders of an interest in any ADSs about the requirements of Cayman Islands or People’s Republic of China law, rules or regulations or any changes therein or thereto.

Additionally, none of us, the depositary or the custodian shall be liable for the failure by any registered holder of ADRs or beneficial owner therein to obtain the benefits of credits on the basis of non-U.S. tax paid against such holder’s or beneficial owner’s income tax liability. Neither we nor the depositary shall incur any liability for any tax consequences that may be incurred by registered holders or beneficial owners on account of their ownership of ADRs or ADSs.

Neither the depositary nor its agents will be responsible for any failure to carry out any instructions to vote any of the deposited securities, for the manner in which any such vote is cast or for the effect of any such vote. The depositary may rely upon instructions from us or our counsel in respect of any approval or license required for any currency conversion, transfer or distribution. The depositary shall not incur any liability for the content of any information submitted to it by us or on our behalf for distribution to ADR holders or for any inaccuracy of any translation thereof, for any investment risk associated with acquiring an interest in the deposited securities, for the validity or worth of the deposited securities, for the credit-worthiness of any third party, for allowing any rights to lapse upon the terms of the deposit agreement or for the failure or timeliness of any notice from us. The depositary shall not be liable for any acts or omissions made by a successor depositary whether in connection with a previous act or omission of the depositary or in connection with any matter arising wholly after the removal or resignation of the depositary. Neither the depositary nor any of its agents shall be liable to registered holders or beneficial owners of interests in ADSs for any indirect, special, punitive or consequential damages (including, without limitation, legal fees and expenses) or lost profits, in each case of any form incurred by any person or entity, whether or not foreseeable and regardless of the type of action in which such a claim may be brought.

TABLE OF CONTENTS

In the deposit agreement each party thereto (including, for avoidance of doubt, each holder and beneficial owner and/or holder of interests in ADRs) irrevocably waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in any suit, action or proceeding against the depositary and/or us directly or indirectly arising out of or relating to the Class A ordinary shares or other deposited securities, the ADSs or the ADRs, the deposit agreement or any transaction contemplated therein, or the breach thereof (whether based on contract, tort, common law or any other theory).

The depositary and its agents may own and deal in any class of securities of our company and our affiliates and in ADRs.

Disclosure of Interest in ADSs

To the extent that the provisions of or governing any deposited securities may require disclosure of or impose limits on beneficial or other ownership of deposited securities, other shares and other securities and may provide for blocking transfer, voting or other rights to enforce such disclosure or limits, you agree to comply with all such disclosure requirements and ownership limitations and to comply with any reasonable instructions we may provide in respect thereof. We reserve the right to instruct you to deliver your ADSs for cancellation and withdrawal of the deposited securities so as to permit us to deal with you directly as a holder of shares and, by holding an ADS or an interest therein, you will be agreeing to comply with such instructions.

Books of Depositary

The depositary or its agent will maintain a register for the registration, registration of transfer, combination and split-up of ADRs, which register shall include the depositary’s direct registration system. Registered holders of ADRs may inspect such records at the depositary’s office at all reasonable times, but solely for the purpose of communicating with other holders in the interest of the business of our company or a matter relating to the deposit agreement. Such register may be closed at any time or from time to time, when deemed expedient by the depositary.

The depositary will maintain facilities for the delivery and receipt of ADRs.

Pre-release of ADSs

In its capacity as depositary, the depositary shall not lend shares or ADSs; provided, however, that the depositary may (i) issue ADSs prior to the receipt of Class A ordinary shares and (ii) deliver Class A ordinary shares prior to the receipt of ADSs for withdrawal of deposited securities, including ADSs which were issued under (i) above but for which shares may not have been received (each such transaction a “pre-release”). The depositary may receive ADSs in lieu of Class A ordinary shares under (i) above (which ADSs will promptly be canceled by the depositary upon receipt by the depositary) and receive Class A ordinary shares in lieu of ADSs under (ii) above. Each such pre-release will be subject to a written agreement whereby the person or entity (the “applicant”) to whom ADSs or Class A ordinary shares are to be delivered (a) represents that at the time of the pre-release the applicant or its customer owns the Class A ordinary shares or ADSs that are to be delivered by the applicant under such pre-release, (b) agrees to indicate the depositary as owner of such Class A ordinary shares or ADSs in its records and to hold such Class A ordinary shares or ADSs in trust for the depositary until such Class A ordinary shares or ADSs are delivered to the depositary or the custodian, (c) unconditionally guarantees to deliver to the depositary or the custodian, as applicable, such Class A ordinary shares or ADSs, and (d) agrees to any additional restrictions or requirements that the depositary deems appropriate. Each such pre-release will be at all times fully collateralized with cash, U.S. government securities or such other collateral as the depositary deems appropriate, terminable by the depositary on not more than five (5) business days’ notice and subject to such further indemnities and credit regulations as the depositary deems appropriate. The depositary will normally limit the number of ADSs and Class A ordinary shares involved in such pre-release at any one time to thirty percent (30%) of the ADSs outstanding (without giving effect to ADSs outstanding under (i) above), provided, however, that the depositary reserves the right to change or disregard such limit from time to time as it deems appropriate. The depositary may also set limits with respect to the number of ADSs and Class A ordinary shares involved in pre-release with any one person on a case-by-case basis as it deems appropriate. The depositary may retain for its own account any

TABLE OF CONTENTS

compensation received by it in conjunction with the foregoing. Collateral provided in connection with pre-release transactions, but not the earnings thereon, shall be held for the benefit of the ADR holders (other than the applicant).

Appointment

In the deposit agreement, each registered holder of ADRs and each person holding an interest in ADSs, upon acceptance of any ADSs (or any interest therein) issued in accordance with the terms and conditions of the deposit agreement will be deemed for all purposes to:

•

be a party to and bound by the terms of the deposit agreement and the applicable ADR or ADRs, and

•

appoint the depositary its attorney-in-fact, with full power to delegate, to act on its behalf and to take any and all actions contemplated in the deposit agreement and the applicable ADR or ADRs, to adopt any and all procedures necessary to comply with applicable laws and to take such action as the depositary in its sole discretion may deem necessary or appropriate to carry out the purposes of the deposit agreement and the applicable ADR and ADRs, the taking of such actions to be the conclusive determinant of the necessity and appropriateness thereof.

Conversion Between ADS and Class A Ordinary Shares

In connection with our initial public offering of Class A ordinary shares in Hong Kong, or the Hong Kong IPO, we have established a branch register of members in Hong Kong, or the Hong Kong share register, which is maintained by our Hong Kong Share Registrar, Computershare Hong Kong Investor Services Limited. Our principal register of members, or the Cayman share register, will continue to be maintained by our principal share registrar, Conyers Trust Company (Cayman) Limited.

All Class A ordinary shares offered in the Hong Kong IPO are registered on the Hong Kong share register in order to be listed and traded on the Hong Kong Stock Exchange. As described in further detail below, holders of Class A ordinary shares registered on the Hong Kong share register are able to convert these shares into ADSs, and vice versa.

In connection with the Hong Kong public offering, and to facilitate fungibility and conversion between ADSs and Class A ordinary shares and trading between the Nasdaq and the Hong Kong Stock Exchange, we moved a portion of our issued Class A ordinary shares that are represented by ADSs from our Cayman share register to our Hong Kong share register.

Our ADSs

Our ADSs representing our Class A ordinary shares are traded on the Nasdaq Global Market, or Nasdaq. Dealings in our ADSs on Nasdaq are conducted in U.S. dollars.

ADSs may be held either:

•

directly, by having a certificated ADS, or an ADR, registered in the holder’s name, or by holding in the direct registration system, pursuant to which the depositary may register the ownership of uncertificated ADSs, which ownership shall be evidenced by periodic statements issued by the depositary to the ADS holders entitled thereto; or

•

indirectly, by holding a security entitlement in ADSs through a broker or other financial institution that is a direct or indirect participant in The Depository Trust Company.

Converting Class A Ordinary Shares Trading in Hong Kong into ADSs

An investor who holds ordinary shares registered in Hong Kong and who intends to convert them to ADSs to trade on Nasdaq must deposit or have his or her broker deposit the Class A ordinary shares with the depositary’s Hong Kong custodian, JP Morgan Chase Bank, N.A., Hong Kong Branch, or the custodian, in exchange for ADSs.

A deposit of Class A ordinary shares trading in Hong Kong in exchange for ADSs involves the following procedures:

TABLE OF CONTENTS

•

If Class A ordinary shares have been deposited with CCASS, the investor must transfer Class A ordinary shares to the depositary’s account with the custodian within CCASS by following the CCASS procedures for transfer and submit and deliver a duly completed and signed conversion form to the depositary via his or her broker.

•

If Class A ordinary shares are held outside CCASS, the investor must arrange to deposit his or her Class A ordinary shares into CCASS for delivery to the depositary’s account with the custodian within CCASS, submit and deliver a request for conversion form to the custodian and after duly completing and signing such conversion form, and deliver such conversion form to the custodian.

•

Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, if applicable, the depositary will issue the corresponding number of ADSs in the name(s) requested by an investor and will deliver the ADSs to the designated DTC account of the person(s) designated by an investor or his or her broker.

For Class A ordinary shares deposited in CCASS, under normal circumstances, the above steps generally require two business days. For Class A ordinary shares held outside CCASS in physical form, the above steps may take 14 business days, or more, to complete. Temporary delays may arise. For example, the transfer books of the depositary may from time to time be closed to ADS issuances. The investor will be unable to trade the ADSs until the procedures are completed.

Converting ADSs to Class A Ordinary Shares Trading in Hong Kong

An investor who holds ADSs and who intends to convert his/her ADSs into Class A ordinary shares to trade on the Hong Kong Stock Exchange must cancel the ADSs the investor holds and withdraw Class A ordinary shares from our ADS program and cause his or her broker or other financial institution to trade such ordinary shares on the Hong Kong Stock Exchange.

An investor that holds ADSs indirectly through a broker should follow the broker’s procedure and instruct the broker to arrange for cancellation of the ADSs, and transfer of the underlying ordinary shares from the depositary’s account with the custodian within the CCASS system to the investor’s Hong Kong stock account.

For investors holding ADSs directly, the following steps must be taken:

•

To withdraw Class A ordinary shares from our ADS program, an investor who holds ADSs may turn in such ADSs at the office of the depositary (and the applicable ADR(s) if the ADSs are held in certificated form), and send an instruction to cancel such ADSs to the depositary.

•

Upon payment or net of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, if applicable, the depositary will instruct the custodian to deliver Class A ordinary shares underlying the cancelled ADSs to the CCASS account designated by an investor.

•

If an investor prefers to receive Class A ordinary shares outside CCASS, he or she must receive Class A ordinary shares in CCASS first and then arrange for withdrawal from CCASS. Investors can then obtain a transfer form signed by HKSCC Nominees Limited (as the transferor) and register Class A ordinary shares in their own names with the Hong Kong Share Registrar.

For Class A ordinary shares to be received in CCASS, under normal circumstances, the above steps generally require two business days. For Class A ordinary shares to be received outside CCASS in physical form, the above steps may take 14 business days, or more, to complete. The investor will be unable to trade the Class A ordinary shares on the Hong Kong Stock Exchange until the procedures are completed.

Temporary delays may arise. For example, the transfer books of the depositary may from time to time be closed to ADS cancellations. In addition, completion of the above steps and procedures is subject to there being a sufficient number of Class A ordinary shares on the Hong Kong share register to facilitate a withdrawal from the ADS program directly into the CCASS system. We are not under any obligation to maintain or increase the number of Class A ordinary shares on the Hong Kong share register to facilitate such withdrawals.

TABLE OF CONTENTS

Depositary Requirements

Before the depositary issues ADSs or permits withdrawal of ordinary shares, the depositary may require:

•

production of satisfactory proof of the identity and genuineness of any signature or other information it deems necessary; and

•

compliance with procedures it may establish, from time to time, consistent with the deposit agreement, including presentation of transfer documents.

The depositary may refuse to deliver, transfer, or register issuances, transfers and cancellations of ADSs generally when the transfer books of the depositary or our Hong Kong or Cayman Share Registrars are closed or at any time if the depositary or we determine it advisable to do so or if it would violate any applicable law or the Depository’s policies and procedures.

All costs attributable to the transfer of Class A ordinary shares to effect a withdrawal from or deposit of ordinary shares into our ADS program will be borne by the investor requesting the transfer. In particular, holders of ordinary shares and ADSs should note that the Hong Kong Share Registrar will charge between HK$2.50 to HK$20, depending on the speed of service (or such higher fee as may from time to time be permitted under the Hong Kong Listing Rules), for each transfer of ordinary shares from one registered owner to another, each share certificate cancelled or issued by it and any applicable fee as stated in the share transfer forms used in Hong Kong. In addition, holders of Class A ordinary shares and ADSs must pay up to US$5.00 (or less) per 100 ADSs for each issuance of ADSs and each cancellation of ADSs, as the case may be, in connection with the deposit of Class A ordinary shares into, or withdrawal of Class A ordinary shares from, our ADS program.

Governing Law

The deposit agreement and the ADRs shall be governed by and construed in accordance with the laws of the State of New York. In the deposit agreement, we have submitted to the jurisdiction of the courts of the State of New York and appointed an agent for service of process on our behalf. Notwithstanding the foregoing, (i) any action based on the deposit agreement or the transactions contemplated thereby may be instituted by the depositary in any competent court in the Cayman Islands, Hong Kong, the People’s Republic of China and/or the United States, (ii) the depositary may, in its sole discretion, elect to institute any action, controversy, claim or dispute directly or indirectly based on, arising out of or relating to the deposit agreement or the ADRs or the transactions contemplated thereby, including without limitation any question regarding its or their existence, validity, interpretation, performance or termination, against any other party or parties to the deposit agreement (including, without limitation, against ADR holders and owners of interests in ADSs), by having the matter referred to and finally resolved by an arbitration conducted under the terms described below, and (iii) the depositary may in its sole discretion require that any action, controversy, claim, dispute, legal suit or proceeding brought against the depositary by any party or parties to the deposit agreement (including, without limitation, by ADR holders and owners of interests in ADSs) shall be referred to and finally settled by an arbitration conducted under the terms described below. Any such arbitration shall be conducted in the English language either in New York, New York in accordance with the Commercial Arbitration Rules of the American Arbitration Association or in Hong Kong following the arbitration rules of the United Nations Commission on International Trade Law (UNCITRAL).

By holding an ADS or an interest therein, registered holders of ADRs and owners of ADSs each irrevocably agree that any legal suit, action or proceeding against or involving us or the depositary, arising out of or based upon the deposit agreement, the ADSs or the transactions contemplated thereby, may only be instituted in a state or federal court in New York, New York, and each irrevocably waives any objection which it may have to the laying of venue of any such proceeding, and irrevocably submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding.

TABLE OF CONTENTS

ENFORCEABILITY OF CIVIL LIABILITIES

We are incorporated under the laws of the Cayman Islands as an exempted company with limited liability. We are incorporated in the Cayman Islands because of certain benefits associated with being a Cayman Islands corporation, such as political and economic stability, an effective judicial system, a favorable tax system, the absence of foreign exchange control or currency restrictions and the availability of professional and support services. However, the Cayman Islands has a less developed body of securities laws as compared to the United States and provides protections for investors to a lesser extent. In addition, Cayman Islands companies may not have standing to sue before the federal courts of the United States.

Substantially all of our operations are conducted in China, and substantially all of our assets are located in China. In addition, most of our directors and officers are residents of jurisdictions other than the United States and all or a substantial portion of their assets are located outside the United States. As a result, it may be difficult for investors to effect service of process within the United States upon us or these persons, or to enforce against us or them judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States. It may also be difficult for you to enforce in United States courts judgments obtained in United States courts based on the civil liability provisions of the United States federal securities laws against us and our officers and directors.

We have appointed Cogency Global Inc. as our agent to receive service of process with respect to any action brought against us in the United States District Court for the Southern District of New York under the federal securities laws of the United States or of any state in the United States or any action brought against us in the Supreme Court of the State of New York in the County of New York under the securities laws of the State of New York.

Conyers Dill & Pearman, our counsel as to Cayman Islands law, and King & Wood Mallesons, our counsel as to PRC law, have advised us that there is uncertainty as to whether the courts of the Cayman Islands or the PRC would, respectively, (1) recognize or enforce judgments of United States courts obtained against us or our directors or officers predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States and (2) entertain original actions brought in the Cayman Islands or the PRC against us or our directors or officers predicated upon the securities laws of the United States or any state in the United States.

Conyers Dill & Pearman has informed us that the uncertainty with regard to Cayman Islands law relates to whether a judgment obtained from the United States courts under the civil liability provisions of the securities laws will be determined by the courts of the Cayman Islands as penal or punitive in nature. If such a determination is made, the courts of the Cayman Islands will not recognize or enforce the judgment against a Cayman company. Because the courts of the Cayman Islands have yet to rule on whether such judgments are penal or punitive in nature, it is uncertain whether they would be enforceable in the Cayman Islands. Conyers Dill & Pearman has further advised us that a final and conclusive judgment in the federal or state courts of the United States under which a sum of money is payable, other than a sum payable in respect of taxes, fines, penalties or similar charges, may be subject to enforcement proceedings as a debt in the courts of the Cayman Islands under the common law doctrine of obligation.

In addition, Conyers Dill & Pearman has advised us that there is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the Cayman Islands will generally recognize as a valid judgment, a final and conclusive judgment in personam obtained in the federal or state courts in the United States under which a sum of money is payable (other than a sum of money payable in respect of multiple damages, taxes or other charges of a like nature or in respect of a fine or other penalty) and would give a judgment based thereon provided that (i) such courts had proper jurisdiction over the parties subject to such judgment; (ii) such courts did not contravene the rules of natural justice of the Cayman Islands; (iii) such judgment was not obtained by fraud; (iv) the enforcement of the judgment would not be contrary to the public policy of the Cayman Islands; (v) no new admissible evidence relevant to the action is submitted prior to the rendering of the judgment by the courts of the Cayman Islands; and (vi) there is due compliance with the correct procedures under the laws of the Cayman Islands.

King & Wood Mallesons has advised us that the recognition and enforcement of foreign judgments are provided for under the PRC Civil Procedure Law. PRC courts may recognize and enforce foreign judgments in

PLAN OF DISTRIBUTION

We and the selling shareholders may sell the securities offered through this prospectus (1) to or through underwriters or dealers, (2) directly to purchasers, including our affiliates, (3) through agents, or (4) through a combination of any these methods. The securities may be distributed at a fixed price or prices, which may be changed, market prices prevailing at the time of sale, prices related to the prevailing market prices, or negotiated prices. The prospectus supplement will include the following information, if applicable:

•

the terms of the offering;

•

the names of any underwriters, dealers or agents;

•

the name or names of any managing underwriter or underwriters;

•

the purchase price of the securities;

•

the net proceeds from the sale of the securities;

•

any delayed delivery arrangements;

•

any underwriting discounts, commissions and other items constituting underwriters’ compensation;

•

any offering price to the public;

•

any discounts or concessions allowed or reallowed or paid to dealers; and

•

any commissions paid to agents.

Sale through underwriters or dealers

If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any public offering price and any discounts or concessions allowed or reallowed or paid to dealers. The prospectus supplement will include the names of the principal underwriters the respective amount of securities underwritten, the nature of the obligation of the underwriters to take the securities and the nature of any material relationship between an underwriter and us.

If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.

Direct sales and sales through agents

We and the selling shareholders may sell the securities offered through this prospectus directly. In this case, no underwriters or agents would be involved. Such securities may also be sold through agents designated from time to time. The prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent by us and the selling shareholders. Unless otherwise indicated in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We and the selling shareholders may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such sales will be described in the prospectus supplement.

TABLE OF CONTENTS

Delayed delivery contracts

If the prospectus supplement indicates, we or the selling shareholders may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

Market making, stabilization and other transactions

Unless the applicable prospectus supplement states otherwise or the shares are offered by the selling shareholders, each series of offered securities will be a new issue and will have no established trading market. We may elect to list any series of offered securities on an exchange. Any underwriters that we and the selling shareholders use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.

Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Exchange Act. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

Derivative transactions and hedging

We, the selling shareholders, the underwriters or other agents may engage in derivative transactions involving the securities. These derivatives may consist of short sale transactions and other hedging activities. The underwriters or agents may acquire a long or short position in the securities, hold or resell securities acquired and purchase options or futures on the securities and other derivative instruments with returns linked to or related to changes in the price of the securities. In order to facilitate these derivative transactions, we may enter into security lending or repurchase agreements with the underwriters or agents. The underwriters or agents may effect the derivative transactions through sales of the securities to the public, including short sales, or by lending the securities in order to facilitate short sale transactions by others. The underwriters or agents may also use the securities purchased or borrowed from us, the selling shareholders or others (or, in the case of derivatives, securities received from us or the selling shareholders in settlement of those derivatives) to directly or indirectly settle sales of the securities or close out any related open borrowings of the securities.

If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be named in the applicable prospectus supplement. In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus and an applicable prospectus supplement. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

Electronic auctions

We and the selling shareholders may also make sales through the Internet or through other electronic means. Since we and the selling shareholders may from time to time elect to offer securities directly to the public, with

TABLE OF CONTENTS

or without the involvement of agents, underwriters or dealers, utilizing the Internet or other forms of electronic bidding or ordering systems for the pricing and allocation of such securities, you should pay particular attention to the description of that system we will provide in a prospectus supplement.

Such electronic system may allow bidders to directly participate, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us, and which may directly affect the price or other terms and conditions at which such securities are sold. These bidding or ordering systems may present to each bidder, on a so-called “real-time” basis, relevant information to assist in making a bid, such as the clearing spread at which the offering would be sold, based on the bids submitted, and whether a bidder’s individual bids would be accepted, prorated or rejected. Of course, many pricing methods can and may also be used.

Upon completion of such an electronic auction process, securities will be allocated based on prices bid, terms of bid or other factors. The final offering price at which securities would be sold and the allocation of securities among bidders would be based in whole or in part on the results of the Internet or other electronic bidding process or auction.

General information

Agents, underwriters, and dealers may be entitled, under agreements entered into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act.
