Investment Objective

The ARK Innovation ETF’s (“Fund”) investment objective is long-term growth of capital.

Fund Fees and Expenses

The table below describes the fees and expenses that you pay if you buy, hold and sell shares of the Fund (“Shares”). Investors may pay other fees, such as brokerage commissions and other fees to financial intermediaries on their purchases and sales of Shares, which are not reflected in the tables and examples below.

(a)

Pursuant to a Supervision Agreement, ARK Investment Management LLC (“ARK” or “Adviser”) pays all other expenses of the Fund (other than acquired fund fees and expenses, taxes and governmental fees, brokerage fees, commissions and other transaction expenses, certain foreign custodial fees and expenses, costs of borrowing money, including interest expenses, and extraordinary expenses (such as litigation and indemnification expenses)).

​

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example does not take into account brokerage commissions that you pay when purchasing or selling Shares.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The example also assumes that your investment has a 5% annual return and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may result in higher transaction costs and higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 71% of the average value of its portfolio.

Principal Investment Strategies

The Fund is an actively-managed exchange-traded fund (“ETF”) that will invest under normal circumstances primarily (at least 65% of its assets) in domestic and foreign equity securities of

companies that are relevant to the Fund’s investment theme of disruptive innovation. The Adviser defines “disruptive innovation” as the introduction of a technologically enabled new product or service that potentially changes the way the world works. The Adviser believes that companies relevant to this theme are those that rely on or benefit from the development of new products or services, technological improvements and advancements in scientific research relating to the areas of genomics* (“Genomic Revolution Companies”); innovation in automation and manufacturing (“Automation Transformation Companies”), transportation, energy (“Energy Transformation Companies”), artificial intelligence (“Artificial Intelligence Companies”) and materials; the increased use of shared technology, infrastructure and services (“Next Generation Internet Companies”); and technologies that make financial services more efficient (“Fintech Innovation Companies”).

In selecting companies that the Adviser believes are relevant to a particular investment theme, the Adviser seeks to identify, using its own internal research and analysis, companies capitalizing on disruptive innovation or that are enabling the further development of a theme in the markets in which they operate. The Adviser’s internal research and analysis leverages insights from diverse sources, including external research, to develop and refine its investment themes and identify and take advantage of trends that have ramifications for individual companies or entire industries. The types of companies that the Adviser believes are Genomic Revolution Companies, Automation Transformation Companies, Energy Transformation Companies, Artificial Intelligence Companies, Next Generation Internet Companies or Fintech Innovation Companies are described below:

•

Genomic Revolution Companies.   Companies that the Adviser believes are substantially focused on and are expected to substantially benefit from extending and enhancing the quality of human and other life by incorporating technological and scientific developments, improvements and advancements in genomics into their business, such as by offering new products or services that rely on genomic sequencing,** analysis, synthesis or instrumentation. These companies may include ones across multiple sectors, such as healthcare, information technology, materials, energy and consumer discretionary. These companies may also develop, produce, manufacture or significantly rely on or enable bionic devices, bio-inspired computing, bioinformatics,*** molecular medicine and agricultural biotechnology.

​

•

Automation Transformation Companies.   Companies that the Adviser believes are focused on man capitalizing on the productivity of machines, such as through the automation of functions, processes or activities previously performed by human labor, such as transportation through an emphasis on mobility as a service, or the use of robotics to perform other functions, activities or processes.

​

•

Energy Transformation Companies.   Companies that the Adviser believes seek to capitalize on innovations or evolutions in: (i) ways that energy is stored or used; (ii) the discovery, collection and/or implementation of new sources of energy, including unconventional sources of oil or natural gas; and/or (iii) the production or development of new materials for use in commercial applications of energy production, use or storage.

​

•

Artificial Intelligence Companies.   Companies that the Adviser considers to be Artificial Intelligence (“AI”) Companies include a company that: (i) designs, creates, integrates, or delivers robotics, autonomous technology, and/or AI in the form of products, software, or systems; (ii) develops the building block components for robotics, autonomous technology, or AI, such as advanced machinery, semiconductors and databases used for machine

​

*

The Adviser defines “genomics” as the study of genes and their functions, and related techniques (e.g., genomic sequencing).

​

**

The Adviser uses the term “genomic sequencing” to refer to techniques that allow researchers to read and decipher the genetic information found in the DNA (i.e., the exact sequence of bases A, C, G and T in a DNA molecule), including the DNA of bacteria, plants, animals and human beings.

​

***

The Adviser defines “bioinformatics” as the science of collecting and analyzing complex biological data such as genetic codes.

learning; (iii) provides its own value-added services on top of such building block components, but are not core to the company’s product or service offering; and/or (iv) develops computer systems that are able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages.

•

Next Generation Internet Companies.   Companies that the Adviser believes are focused on and expected to benefit from shifting the bases of technology infrastructure from hardware and software to the cloud, enabling mobile and local services, such as companies that rely on or benefit from the increased use of shared technology, infrastructure and services. These companies may include mail order houses which generate the entirety of their business through websites and which offer internet-based products and services, such as streaming media or cloud storage in addition to traditional physical goods. These companies may also include ones that develop, use or rely on innovative payment methodologies, big data, the “internet of things*,” machine learning, and social distribution and media.

​

•

Fintech Innovation Companies.   Companies that the Adviser believes are focused on and expected to benefit from the shifting of the financial sector and economic transactions to technology infrastructure platforms, and technological intermediaries. Fintech Innovation Companies may also develop, use or rely on innovative payment platforms and methodologies, point of sale providers, e-commerce, transactional innovations, business analytics, fraud reduction, frictionless funding platforms, peer-to-peer lending, blockchain technologies,** intermediary exchanges, asset allocation technology, cryptocurrency,*** mobile payments, and risk pricing and pooling aggregators. The Fund may have exposure to cryptocurrency, such as bitcoin, indirectly through an investment in a grantor trust. The Fund’s exposure to cryptocurrency may change over time and, accordingly, such exposure may not always be represented in the Fund’s portfolio.

​

The Adviser will select investments for the Fund that represent its highest-conviction investment ideas within the theme of disruptive innovation, as described above, in constructing the Fund’s portfolio. The Adviser’s process for identifying Genomic Revolution Companies, Automation Transformation Companies, Energy Transformation Companies, Artificial Intelligence Companies, Next Generation Internet Companies and Fintech Innovation Companies uses both “top down” (thematic research sizing the potential total available market, and surfacing the prime beneficiaries) and “bottom up” ​(valuation, fundamental and quantitative measures) approaches. In both the Adviser’s “top down” and “bottom up” approaches, the Adviser evaluates environmental, social, and governance (“ESG”) considerations. In its “top down” approach, the Adviser uses the framework of the United Nations Sustainable Development Goals to integrate ESG considerations into its research and investment process. The Adviser, however, does not use ESG considerations to limit, restrict or otherwise exclude companies or sectors from the Fund’s investment universe. In its “bottom up” approach, the Adviser makes its investment decisions primarily based on its analysis of

*

The Adviser defines the “internet of things” as a system of interrelated computing devices, mechanical and digital machines, or physical objects that are provided unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

​

**

The term “blockchain” refers to a peer-to-peer distributed ledger that is secured using cryptography. A distributed ledger is a shared electronic database where information is recorded and stored across multiple computers; a blockchain is one type of distributed ledger. A blockchain may be open and permissionless or private and permissioned. The Bitcoin and Ethereum blockchains are examples of open, public, permissionless blockchains.. Blockchain derives its name from the way it stores transaction data in “blocks” that are linked together to form a chain. As the number of transactions grows, so does the blockchain. Blocks record and confirm the time and sequence of transactions, which are then logged into the blockchain network, which is, with respect to public blockchains, governed by rules agreed on by the network participants.

the potential of individual companies, while integrating ESG considerations into that process. The Adviser’s highest-conviction investment ideas are those that it believes present the best risk-reward opportunities.

Under normal circumstances, substantially all of the Fund’s assets will be invested in equity securities, including common stocks, partnership interests, business trust shares and other equity investments or ownership interests in business enterprises. The Fund’s investments will include micro-, small-, medium- and large-capitalization companies. The Fund’s investments in foreign equity securities will be in both developed and emerging markets. The Fund may invest in foreign securities listed on foreign exchanges as well as American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”).

The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940, as amended (the “1940 Act”), which means that it may invest a high percentage of its assets in a limited number of issuers.

Principal Risks

There is no assurance that the Fund will meet its investment objective. The value of your investment in the Fund, as well as the amount of return you receive on your investment in the Fund, may fluctuate significantly. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. Therefore, you should consider carefully the following risks before investing in the Fund. The principal risks of investing in the Fund listed below are presented alphabetically to facilitate your ability to find particular risks and compare them with the risks of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.

Authorized Participants Concentration Risk.   The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”) on an agency basis (i.e., on behalf of other market participants). To the extent that those APs exit the business or are unable to process creation and/or redemption orders, and no other AP is able to step forward to create and redeem in either of these cases, Shares may possibly trade at a discount to net asset value (“NAV”). The AP risk may be heightened in the case of ETFs investing internationally because international ETFs often require APs to post collateral, which only certain APs are able to do.

Communications Sector Risk.   The Fund will be more affected by the performance of the communications sector than a fund with less exposure to such sector. Communication companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communications sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communications sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

Consumer Discretionary Risk.   The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Cryptocurrency Risk.   Cryptocurrencies (also referred to as “virtual currencies” and “digital currencies”) are digital assets designed to act as a medium of exchange. Cryptocurrency is an emerging asset class. There are thousands of cryptocurrencies, the most well-known of which is bitcoin. The Fund may have exposure to bitcoin indirectly through an investment in the Grayscale Bitcoin Trust (“GBTC”), a privately offered, open-end investment vehicle that invests in bitcoin.

Cryptocurrency generally operates without central authority (such as a bank) and is not backed by any government, corporation, or other entity. Cryptocurrency is not generally accepted as legal tender. Regulation of cryptocurrency is still developing. Federal, state and/or foreign governments may restrict the development, use, or exchange of cryptocurrency.

The market price of bitcoin has been subject to extreme fluctuations. The price of bitcoin could fall sharply (potentially to zero) for various reasons, including, but not limited to, regulatory changes, issues impacting the bitcoin network, events involving entities that facilitate transactions in bitcoin, or changes in user preferences in favor of alternative cryptocurrencies. Furthermore, events that impact one cryptocurrency may lead to a decline in the value of other cryptocurrencies, including bitcoin.

Cryptocurrency exchanges and other trading venues on which cryptocurrencies trade are relatively new and, in most cases, largely unregulated. Therefore, cryptocurrency exchanges may be more exposed to fraud and failure than established, regulated exchanges for securities, derivatives and other currencies. Cryptocurrency exchanges may not have the same features as traditional exchanges to enhance the stability of trading on the exchange, such as measures designed to prevent sudden price swings such as “flash crashes.” As a result, the prices of cryptocurrencies on exchanges may be subject to more volatility than traditional assets traded on regulated exchanges. Cryptocurrency exchanges are also subject to cyber security risks. Cryptocurrency exchanges have experienced cyber security breaches in the past and may be breached in the future, which could result in the theft and/or loss of bitcoin and other cryptocurrencies and impact the value of bitcoin. Furthermore, cyber security events, legal or regulatory actions, fraud, and technical glitches, may cause a cryptocurrency exchange to shut down temporarily or permanently, which may also affect the value of bitcoin.

The Fund’s investments in GBTC expose the Fund to all of the risks related to cryptocurrencies described above and also expose the Fund to risks related to GBTC directly. Shares of GBTC may trade at a significant premium or discount to NAV. To the extent GBTC trades at a discount to NAV, the value of the Fund’s investment in GBTC would typically decrease. Similar to fiat currencies (i.e., a currency that is backed by a central bank or a national, supra-national or quasi-national organization), cryptocurrencies, including bitcoin, are susceptible to theft, loss and destruction. If GBTC experiences theft, loss, or destruction of its bitcoin holdings, the Fund’s investments in GBTC could be harmed. Furthermore, because there is no guarantee that an active trading market for GBTC will exist at any time, the Fund’s investments in GBTC may also be subject to liquidity risk, which can impair the value of the Fund’s investments in GBTC. Investors may experience losses if the value of the Fund’s investments in GBTC decline.

Cryptocurrency Tax Risk.   Many significant aspects of the U.S. federal income tax treatment of investments in bitcoin are uncertain and an investment in bitcoin may produce income that is not treated as qualifying income for purposes of the income test applicable to regulated investment companies, such as the Fund. GBTC is expected to be treated as a grantor trust for U.S. federal income tax purposes, and therefore an investment by the Fund in GBTC will generally be treated as a direct investment in bitcoin for such purposes. See “Taxes” in the Fund’s Statement of Additional Information for more information.

Currency Risk.   Changes in currency exchange rates will affect the value of non-U.S. dollar denominated securities, the value of dividends and interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to other currencies will adversely affect the value of the Fund’s investments denominated in those other currencies.

Cyber Security Risk.   As the use of Internet technology has become more prevalent in the course of business, funds have become more susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events from external or internal sources that may cause the Fund to lose proprietary information, suffer data corruption, lose operational capacity, or result in unauthorized access to confidential information.

 

5

 

Such events could prevent the Fund from engaging in normal business activities and cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve, among other things, unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding, ransomware attacks that impair the Fund’s ability to access its data or systems until a ransom is paid, or denial-of-service attacks that make network services unavailable to intended users. In addition, cyber security breaches of the Fund’s third-party service providers, such as its adviser, administrator, transfer agent or custodian, the Fund’s trading counterparties, and issuers in which the Fund invests, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Cyber security breaches experienced by an issuer in which the Fund invests can also impact the value of the Fund’s investment in that issuer. While the Fund has established business continuity plans and risk management systems designed to reduce the risks associated with cyber security, there are inherent limitations in such plans and systems. Additionally, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of its third-party service providers, trading counterparties, or issuers.

Depositary Receipts Risk.   Depositary receipts generally involve similar risks to those associated with investments in foreign securities. Depositary receipts are securities that are typically issued by a bank or trust company that evidence ownership of underlying securities issued by a foreign corporation and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign securities. The issuers of certain depositary receipts are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Investments in depositary receipts may be less liquid than the underlying shares in their primary trading market. Depositary receipts may not necessarily be denominated in the same currency as the underlying securities into which they may be converted. In addition, the issuers of the stock underlying unsponsored depositary receipts are not obligated to disclose material information in the United States.

Disruptive Innovation Risk.   Companies that the Adviser believes are capitalizing on disruptive innovation and developing technologies to displace older technologies or create new markets may not in fact do so. Companies that initially develop a novel technology may not be able to capitalize on the technology. Companies that develop disruptive technologies may face political or legal attacks from competitors, industry groups or local and national governments. These companies may also be exposed to risks applicable to sectors other than the disruptive innovation theme for which they are chosen, and the securities issued by these companies may underperform the securities of other companies that are primarily focused on a particular theme. The Fund may invest in a company that does not currently derive any revenue from disruptive innovations or technologies, and there is no assurance that a company will derive any revenue from disruptive innovations or technologies in the future. A disruptive innovation or technology may constitute a small portion of a company’s overall business. As a result, the success of a disruptive innovation or technology may not affect the value of the equity securities issued by the company.

Emerging Market Securities Risk.   Investment in securities of emerging market issuers may present risks that are greater than or different from those associated with foreign securities due to less developed and liquid markets and such factors as increased economic, political, regulatory, or other uncertainties. Certain emerging market countries may be subject to less stringent requirements regarding accounting, auditing, financial reporting and record keeping and therefore, material information related to an investment may not be available or reliable. In addition, the Fund is limited in its ability to exercise its legal rights or enforce a counterparty’s legal obligations in certain jurisdictions outside of the United States, in particular, in emerging markets countries.

Equity Securities Risk.   The value of the equity securities the Fund holds may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities the Fund holds participate or factors relating to specific companies in which the Fund invests. These can include stock movements, purchases or sales of securities by the Fund, government

policies, litigation and changes in interest rates, inflation, the financial condition of the securities’ issuer or perceptions of the issuer, or economic conditions in general or specific to the issuer. Equity securities may also be particularly sensitive to general movements in the stock market, and a decline in the broader market may affect the value of the Fund’s equity investments.

•

Special Purpose Acquisition Companies (SPACs).   The Fund may invest in stock of, warrants to purchase stock of, and other interests in SPACs or similar special purposes entities. A SPAC is a publicly traded company that raises investment capital for the purpose of acquiring or merging with an existing company. Investments in SPACs and similar entities are subject to a variety of risks beyond those associated with other equity securities. Because SPACs and similar entities do not have any operating history or ongoing business other than seeking acquisitions, the value of their securities is particularly dependent on the ability of the SPAC’s management to identify a merger target and complete an acquisition. Until an acquisition or merger is completed, a SPAC generally invests its assets, less a portion retained to cover expenses, in U.S. government securities, money market securities and cash and does not typically pay dividends in respect of its common stock. As a result, it is possible that an investment in a SPAC may lose value.

​

Financial Technology Risk.   Companies that are developing financial technologies that seek to disrupt or displace established financial institutions generally face competition from much larger and more established firms. Fintech Innovation Companies may not be able to capitalize on their disruptive technologies if they face political and/or legal attacks from competitors, industry groups or local and national governments. Laws generally vary by country, creating some challenges to achieving scale. A Fintech Innovation Company may not currently derive any revenue, and there is no assurance that such company will derive any revenue from innovative technologies in the future. Additionally, Fintech Innovation Companies may be adversely impacted by potential rapid product obsolescence, cybersecurity attacks, increased regulatory oversight and disruptions in the technology they depend on.

Foreign Securities Risk.   The Fund’s investments in foreign securities can be riskier than U.S. securities investments. Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. The prices of foreign securities and the prices of U.S. securities have, at times, moved in opposite directions. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market. The Fund normally will not hedge any foreign currency exposure.

Future Expected Genomic Business Risk.   The Adviser may invest some of the Fund’s assets in Genomics Revolution Companies that do not currently derive a substantial portion of their current revenues from genomic-focused businesses and there is no assurance that any company will do so in the future, which may adversely affect the ability of the Fund to achieve its investment objective.

Health Care Sector Risk.   The health care sector may be affected by government regulations and government health care programs, restrictions on government reimbursement for medical expenses, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many health care companies are: (i) heavily dependent on patent protection and intellectual property rights and the expiration of a patent may adversely affect their profitability; (ii) subject to extensive litigation based on product liability and similar claims; and (iii) subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many health care products and services may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and delays or failure to receive such approvals may negatively impact the business of such companies. Additional or more stringent

laws and regulations enacted in the future could have a material adverse effect on such companies in the health care sector. In addition, issuers in the health care sector include issuers having their principal activities in the biotechnology industry, medical laboratories and research, drug laboratories and research and drug manufacturers, which have the additional risks described below.

•

Biotechnology Company Risk.   A biotechnology company’s valuation can often be based largely on the potential or actual performance of a limited number of products and can accordingly be greatly affected if one of its products proves, among other things, unsafe, ineffective or unprofitable. Biotechnology companies are subject to regulation by, and the restrictions of, the U.S. Food and Drug Administration, the U.S. Environmental Protection Agency, state and local governments, and foreign regulatory authorities.

​

•

Pharmaceutical Company Risk.   Companies in the pharmaceutical industry can be significantly affected by, among other things, government approval of products and services, government regulation and reimbursement rates, product liability claims, patent expirations and protection and intense competition.

​

Information Technology Sector Risk.   The information technology sector includes companies engaged in internet software and services, technology hardware and storage peripherals, electronic equipment instruments and components, and semiconductors and semiconductor equipment. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face rapid product obsolescence due to technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Failure to introduce new products, develop and maintain a loyal customer base, or achieve general market acceptance for their products could have a material adverse effect on a company’s business. Companies in the information technology sector are heavily dependent on intellectual property and the loss of patent, copyright and trademark protections may adversely affect the profitability of these companies.

•

Internet Company Risk.   Many Internet-related companies have incurred large losses since their inception and may continue to incur large losses in the hope of capturing market share and generating future revenues. Accordingly, many such companies expect to incur significant operating losses for the foreseeable future, and may never be profitable. The markets in which many Internet companies compete face rapidly evolving industry standards, frequent new service and product announcements, introductions and enhancements, and changing customer demands. The failure of an Internet company to adapt to such changes could have a material adverse effect on the company’s business. Additionally, the widespread adoption of new Internet, networking, telecommunications technologies, or other technological changes could require substantial expenditures by an Internet company to modify or adapt its services or infrastructure, which could have a material adverse effect on an Internet company’s business.

​

•

Semiconductor Company Risk.   Competitive pressures may have a significant effect on the financial condition of semiconductor companies and, as product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Reduced demand for end-user products, under-utilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor sector. Semiconductor companies typically face high capital costs and may be heavily dependent on intellectual property rights. The semiconductor sector is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. The stock prices of companies in the semiconductor sector have been and likely will continue to be extremely volatile.

​

•

Software Industry Risk.   The software industry can be significantly affected by intense competition, aggressive pricing, technological innovations, and product obsolescence.

​

 

8

 

Companies in the software industry are subject to significant competitive pressures, such as aggressive pricing, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in this industry, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many software companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.

International Closed-Market Trading Risk.   Because certain of the Fund’s underlying securities trade on an exchange that is closed when the securities exchange on which Fund Shares list and trade is open, there are likely to be deviations between the current pricing of an underlying security and stale security pricing (i.e., the last quote from its closed foreign market), likely resulting in premiums or discounts to NAV that may be greater than those experienced by ETFs that do not invest in foreign securities.

Issuer Risk.   Because the Fund may invest in approximately 40 to 50 issuers, it is subject to the risk that the value of the Fund’s portfolio may decline due to a decline in value of the equity securities of particular issuers. The value of an issuer’s equity securities may decline for reasons directly related to the issuer, such as management performance and reduced demand for the issuer’s goods or services.

Large-Capitalization Companies Risk.    Large-capitalization companies are generally less volatile than companies with smaller market capitalizations. In exchange for this potentially lower risk, the value of large-capitalization companies may not rise as much as that of companies with smaller market capitalizations.

Management Risk.   As an actively-managed ETF, the Fund is subject to management risk. The ability of the Adviser to successfully implement the Fund’s investment strategies will significantly influence the Fund’s performance. The success of the Fund will depend in part upon the skill and expertise of certain key personnel of the Adviser, and there can be no assurance that any such personnel will continue to be associated with the Fund.

Market Risk.   The value of the Fund’s assets will fluctuate as the markets in which the Fund invests fluctuate. The value of the Fund’s investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events, such as inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, political instability, and infectious disease epidemics or pandemics.

For example, the outbreak of COVID-19, a novel coronavirus disease, has negatively affected economies, markets and individual companies throughout the world, including those in which the Fund invests. The effects of this pandemic to public health and business and market conditions, including exchange trading suspensions and closures may continue to have a significant negative impact on the performance of the Fund’s investments, increase the Fund’s volatility, negatively impact the Fund’s arbitrage and pricing mechanisms, exacerbate pre-existing political, social and economic risks to the Fund, and negatively impact broad segments of businesses and populations. The Fund’s operations may be interrupted as a result, which may contribute to the negative impact

on investment performance. In addition, governments, their regulatory agencies, or self-regulatory organizations may take actions in response to the pandemic that affect the instruments in which the Fund invests, or the issuers of such instruments, in ways that could have a significant negative impact on the Fund’s investment performance. The full impact of the COVID-19 pandemic, or other future epidemics or pandemics, is currently unknown.

Market Trading Risk.   The Fund faces numerous market trading risks, including disruptions to the creation and redemption processes of the Fund, losses from trading in secondary markets, the existence of extreme market volatility, the potential lack of an active trading market for Shares due to market stress, or trading halts impacting the Shares or the Fund’s underlying securities, which may result in Shares trading at a significant premium or discount to their NAV. If a shareholder purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Micro-Capitalization Companies Risk.   Micro-capitalization companies are subject to substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses). Their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. The shares of micro-capitalization companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities.

Next Generation Internet Companies Risk.   The risks described below apply, in particular, to the Fund’s investment in Next Generation Internet Companies.

•

Internet Information Provider Company Risk.   Internet information provider companies provide Internet navigation services and reference guide information and publish, provide or present proprietary advertising and/or third party content. Such companies often derive a large portion of their revenues from advertising, and a reduction in spending by or loss of advertisers could seriously harm their business. This business is rapidly evolving and intensely competitive, and is subject to changing technologies, shifting user needs, and frequent introductions of new products and services. The research and development of new, technologically advanced products is a complex and uncertain process requiring high levels of innovation and investment, as well as the accurate anticipation of technology, market trends and consumer needs. The number of people who access the Internet is increasing dramatically and a failure to attract and retain a substantial number of such users to a company’s products and services or to develop products and technologies that are more compatible with alternative devices, could adversely affect operating results. Concerns regarding a company’s products, services or processes that may compromise the privacy of users or other privacy related matters, even if unfounded, could damage a company’s reputation and adversely affect operating results.

Catalog and Mail Order House Company Risk.   Catalog and mail order house companies may be exposed to significant inventory risks that may adversely affect operating results due to, among other factors: seasonality, new product launches, rapid changes in product cycles and pricing, defective merchandise, changes in consumer demand and consumer spending patterns, or changes in consumer tastes with respect to products. Demand for products can change significantly between the time inventory or components are ordered and the date of sale. The acquisition of certain types of inventory or components may require significant lead-time and prepayment and they may not be returnable. Failure to adequately predict customer demand or otherwise optimize and operate distribution centers could result in excess or insufficient inventory or distribution capacity, result in increased costs, impairment charges, or both. The business of catalog and mail order house companies can be highly seasonal and failure to stock or restock popular products in sufficient amounts during high demand periods could significantly affect revenue and future growth. Increased website traffic during peak periods could cause system

interruptions which may reduce the volume of goods sold and the attractiveness of a company’s products and services.

Non-Diversified Risk.   The Fund is classified as a “non-diversified” investment company under the 1940 Act. Therefore, the Fund may invest a relatively higher percentage of its assets in a relatively smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Small- and Medium-Capitalization Companies Risk.   Small- and medium-capitalization companies may be more volatile and more likely than large-capitalization companies to have narrower product lines, fewer financial resources, less management depth and experience and less competitive strength. Returns on investments in securities of small- and medium-capitalization companies could trail the returns on investments in securities of large-capitalization companies.

Management of the Fund

Investment Adviser.  ARK Investment Management LLC.

Portfolio Manager.  The following individual has been primarily responsible for the day-to-day management of the Fund’s portfolio since the inception of the Fund: Catherine D. Wood.

Purchase and Sale of Fund Shares

The Fund issues and redeems Shares at its NAV only in a large specified number of Shares each called a “Creation Unit,” or multiples thereof, and only with APs who have entered into contractual arrangements with the Fund’s distributor (“Distributor”).

Individual Shares (rather than Creation Units) of the Fund may only be purchased and sold on a national securities exchange through a broker or dealer at market price. The prices at which individual Shares may be purchased and sold on a national securities exchange through brokers are based on market prices and, because Shares will trade at market prices rather than at NAV, individual Shares of the Fund may trade at a price greater than or less than NAV. Shares of the Fund are listed on NYSE Arca, Inc.

An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares of the Fund (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares in the secondary market (the “bid-ask spread”).

Recent information, including information about the Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is included on the Fund’s website at http://ark-funds.com.

Tax Information

The Fund’s distributions are taxable and generally will be taxed as ordinary income or capital gains.

Payments to Broker-Dealers and Other Financial Intermediaries

The Adviser and its related companies may pay broker/dealers or other financial intermediaries (such as a bank) for the sale of the Fund Shares and related services. These payments create a conflict of interest by influencing your broker/dealer, sales persons or other intermediary or its employees or associated persons to recommend the Fund over another investment. Ask your financial adviser or visit your financial intermediary’s website for more information.
