Preliminary Prospectus

Up to 6,896,551 Shares of Common Stock

Pre-Funded Warrants to Purchase up to 6,896,551 Shares of Common Stock

Placement Agent Warrants to Purchase up to 206,897 Shares of Common Stock

7,103,448 Shares of Common Stock Issuable upon the Exercise of Pre-Funded Warrants and Placement Agent Warrants

This is an offering of securities by Sonim Technologies, Inc. We are offering, on a best-efforts basis, up to 6,896,551 shares of our common stock. You should read this prospectus and any prospectus supplement or amendment carefully before you invest in our securities.

We are also offering to those purchasers, if any, whose purchase of our common stock in this offering would otherwise result in such purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% of our outstanding common stock immediately following the consummation of this offering, the opportunity, in lieu of purchasing common stock, to purchase pre-funded warrants to purchase shares of our common stock (“pre-funded warrants”). Each pre-funded warrant will be exercisable for one share of our common stock (subject to adjustment as provided for therein) at any time at the option of the holder until such pre-funded warrant is exercised in full, provided that the holder will be prohibited from exercising pre-funded warrants for shares of our common stock if, as a result of such exercise, the holder, together with its affiliates and certain related parties, would own more than 4.99% of the total number of shares of our common stock then issued and outstanding. However, any holder may increase such percentage to any other percentage, not in excess of 9.99%, provided that any increase in such percentage shall not be effective until 61 days after notice to us. The purchase price of each pre-funded warrant will equal the price per share at which shares of our common stock are being sold to the public in this offering, minus $0.001, and the exercise price of each pre-funded warrant will equal $0.001 per share of common stock. Pursuant to this prospectus, we are also offering the shares of common stock issuable upon the exercise of the pre-funded warrants offered hereby. For each pre-funded warrant purchased in this offering in lieu of common stock, we will reduce the number of shares of common stock we are offering by one.

This offering will terminate on July 31, 2025, unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all the securities purchased in this offering. The public offering price per share (or pre-funded warrant) will be fixed for the duration of this offering.

Our common stock is listed on the Nasdaq Capital Market (“Nasdaq”) under the symbol “SONM.” The last reported sale price of our common stock on June 18, 2025, was $1.45. The public offering price for the securities offered by this prospectus will be determined between us and the investors in this offering at the time of pricing and may be at a discount to the current market price. Therefore, the recent market price of $1.45 per share of common stock used throughout this prospectus may not be indicative of the actual combined public offering price for our common stock or pre-funded warrants, as applicable. There is no established trading market for the pre-funded warrants, and we do not expect a market to develop. In addition, we do not intend to apply for the listing of the pre-funded warrants on any national securities exchange or other trading market. Without an active trading market, the liquidity of the pre-funded warrants will be limited.

We are a “smaller reporting company” as defined under the federal securities laws and, under applicable Securities and Exchange Commission rules, we have elected to comply with certain reduced public company reporting and disclosure requirements.

We have agreed to pay the placement agent fees set forth in the table below, which assumes that we sell all of the securities offered by this prospectus. See “Plan of Distribution” on page 72 of this prospectus for more information regarding these arrangements. There is no minimum number of shares of common stock or pre-funded warrants or minimum aggregate amount of proceeds that is a condition for this offering to close. We may sell fewer than all of the shares of common stock and pre-funded warrants offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund if we do not sell all of the securities offered hereby. In addition, we have not established an escrow account in connection with this offering. Because there is no escrow account and no minimum number of securities or amount of proceeds, investors could be in a position where they have invested in us, but we have not raised sufficient proceeds in this offering to adequately fund the intended uses of the proceeds as described in this prospectus.

Investing in our securities involves a high degree of risk. See the section titled “Risk Factors” beginning on page 9 to read about the factors you should consider before buying shares of our common stock.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Delivery of the common stock or pre-funded warrants offered hereby is expected to be made on or about [          ], 2025, subject to satisfaction of certain customary closing conditions.

INFORMATION ABOUT THIS PROSPECTUS

General Information

This prospectus is part of a registration statement on Form S-1 (File No. 333-              ) that we filed with the Securities and Exchange Commission (the “SEC”). As permitted by SEC rules, this prospectus does not contain all of the information included in the registration statement. For further information, we refer you to the registration statement, including its exhibits. Statements contained in this prospectus about the provisions or contents of any agreement or other document are not necessarily complete. If the SEC’s rules and regulations require that an agreement or document be filed as an exhibit to the registration statement, please see that agreement or document for a complete description of these matters.

You should read this prospectus together with any additional information you may need to make your investment decision. You should also read and carefully consider the information in the documents we have referred you to in “Where You Can Find Additional Information” below.

Unless otherwise stated or the context requires otherwise, when we refer to “Sonim,” “we,” “our,” “us,” and the “Company” in this prospectus, we mean Sonim Technologies, Inc. and its consolidated subsidiaries. When we refer to “you,” we mean the potential investors in our securities.

Trademarks, Trade Names and Service Marks

Solely for convenience, tradenames referred to in this prospectus appear without the ® and ™ symbols, but those references are not intended to indicate, in any way, that we will not assert, to the fullest extent under applicable law, our rights, or that the applicable owner will not assert its rights, to these tradenames. We do not intend our use or display of other companies’ trademarks, trade names, service marks or copyrights to imply a relationship with, or endorsement or sponsorship of us by, such other companies.

Industry and Market Data

The market data and certain other statistical information used throughout this prospectus are based on independent industry publications, government publications or other published independent sources. Although we believe these third-party sources are reliable as of their respective dates, neither we nor the placement agent have independently verified the accuracy or completeness of this information. Some data is also based on our good-faith estimates. The industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of factors, including those described in the section entitled “Risk Factors.” These and other factors could cause results to differ materially from those expressed in any third-party publications or our good-faith estimates.

Basis of Presentation

All information in this prospectus assumes a 1-for-10 reverse stock split of our common stock, which was effected on July 17, 2024 (all share and per share amounts in this prospectus have been presented on a retrospective basis to reflect the reverse stock split).

Certain monetary amounts, percentages and other figures included elsewhere in this prospectus have been subject to rounding adjustments. Percentage amounts included in this prospectus have not in all cases been calculated on the basis of such rounded figures, but on the basis of such amounts prior to rounding. For this reason, percentage amounts in this prospectus may vary from those obtained by performing the same calculations using the figures in our combined/consolidated financial statements included elsewhere in this prospectus. Accordingly, certain other figures and amounts that appear as totals in this prospectus may not be the arithmetic aggregation of the figures or amounts that precede them, and figures or amounts expressed as a percentage may not total 100% or be the arithmetic aggregation of the percentages that precede them.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference herein contain forward-looking statements that involve substantial risks and uncertainties. All statements, other than statements of historical facts, included in this prospectus or the documents incorporated herein by reference regarding our strategy, future operations, future financial position, future revenues, projected costs, prospects, plans, and objectives of management are forward-looking statements. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “will,” “would,” “could,” “should,” “potential,” “seek,” “evaluate,” “pursue,” “continue,” “design,” “impact,” “affect,” “forecast,” “target,” “outlook,” “initiative,” “objective,” “priorities,” “goal,” or the negative of such terms and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.

Forward-looking statements contained in this prospectus include but are not limited to, statements about:

We caution you that the foregoing list may not contain all of the forward-looking statements made in this prospectus.

Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those anticipated by these forward-looking statements. These risks and uncertainties include, but are not limited to, the following:

Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. You should read this prospectus and the documents that we incorporate by reference herein completely and with the understanding that our actual future results may be materially different from what we expect. Except as required by applicable law, we undertake no obligation to update publicly any forward-looking statements for any reason after the date of this prospectus, any prospectus supplement, and the other documents we have filed with the SEC that are incorporated herein by reference to conform such statements to actual results or to changes in our expectations.

Risk Factors

You should carefully consider the risks and uncertainties described below and the other information in this prospectus before making an investment in our common stock. Our business, financial condition, results of operations, or prospects could be materially and adversely affected if any of these risks occur, and as a result, the market price of our common stock could decline and you could lose all or part of your investment. This prospectus also contains forward-looking statements that involve risks and uncertainties. See “Forward-Looking Statements.” Our actual results could differ materially and adversely from those anticipated in these forward-looking statements as a result of certain factors, including those set forth below.

Risks Related to Our Business and Industry

To remain competitive and stimulate consumer and business demand, we must successfully manage the introduction of new products and product lines and the transition and enhancement of existing products.

We operate in a highly competitive, quickly changing environment characterized by evolving industry standards, frequent new product and service introductions, evolving distribution channels, increasing demand for customized product and software solutions, rapid competitive developments; and changing customer demands. Technological advancements could render our products obsolete, which typically erodes prices and causes products to become unmarketable.

Our success will depend on our ability to respond to changing technologies and customer requirements, effectively stimulate customer and business demands for new and upgraded products, and our ability to develop and introduce new and enhanced products in a cost-effective and timely manner. For example, our XP3plus and XP5plus products are compatible with fourth-generation, or 4G, technology, but fifth-generation wireless, or 5G, technology has required us to upgrade our XP3plus and XP5plus to support 5G.

As a result, we are currently prioritizing spending on research and development of our upgrades to 5G and the development of new mobile phones and other data devices. However, the research and development necessary to launch our new products will require us to incur additional costs and our liquidity continues to be adversely impacted by our ongoing net losses. There can be no assurance that we will have sufficient resources to complete the development of our new products and bring them to market. Even if we are able to introduce our new ruggedized mobile phones and data devices to the market, there can be no assurance that these new product introductions will lead to any sales or increase in revenue. If we fail to develop new products on a timely and cost-effective basis, or if our new products fail to achieve market acceptance, our business, operations, financial condition, and liquidity would be further materially adversely affected and we may be required to delay, reduce or cease our operations and we may be required to seek bankruptcy protection.

The development of new or enhanced products is a complex and uncertain process requiring the accurate anticipation of technological and market trends. We may experience design, manufacturing, marketing, and other difficulties that could delay or prevent the development, introduction, or marketing of our new products and enhancements. If we experience delays with new products, if our expectations regarding market demand and direction are incorrect, if sales of our existing products begin to decline more rapidly, or if the rate of decline continues to exceed the rate of growth of our next-generation products, it will materially and adversely affect our business, results of operations and financial condition, and may require us to significantly reduce or even eliminate certain research and development programs.

We participate in a competitive industry, which may become more competitive. Competitors with greater resources and significant experience in high-volume product manufacturing may be able to respond more quickly and cost-effectively than we can to new or emerging technologies and changes in customer requirements.

We face significant competition in developing and selling our solutions. Our primary competitors in the non-rugged mobile device market include Apple Inc. and Samsung Electronics Co. Ltd. Our primary competitor in the rugged mobile device market is Kyocera Corporation. We also face competition from large system integrators and manufacturers of private and public wireless network equipment and devices. Competitors in this space include Harris Corporation, JVC KENWOOD Corporation, Motorola Solutions, Inc., MSI, and Tait International Limited.

We cannot assure we will be able to compete successfully against current or future competitors. Increased competition in mobile computing platforms, or related accessories and software developments may result in price reductions, lower gross profit margins, and loss of market share, and could require increased spending on research and development, sales and marketing, and customer support. Some competitors may make strategic acquisitions or establish cooperative relationships with suppliers or companies that produce complementary products, which may create additional pressures on our competitive position in the marketplace.

Most of our competitors have longer operating histories, greater name recognition, larger customer bases, and significantly greater financial, technical, sales, marketing, and other resources and experience than we do. In addition, because of the higher volume of components that many of our competitors purchase from their suppliers, they are able to keep their supply costs relatively low and, as a result, may be able to recognize higher margins on their product sales than we do. Many of our competitors may also have existing relationships with the channel partners who we use to sell our products, or with our potential customers. This competition may result in reduced prices, reduced margins, and longer sales cycles for our products. Our competitors may also be able to quickly and cost-effectively respond to new or emerging technologies and changes in customer requirements. The combination of brand strength, extensive distribution channels, and financial resources of the larger vendors could cause us to lose market share and could reduce our margins on our products, especially if any of our larger competitors moved into the market for ultra-rugged mobile phones and accessories, as those competitors would enjoy relatively low barriers. If any of our larger competitors were to commit greater technical, sales, marketing, and other resources to our markets, our ability to compete would be adversely impacted. If we are unable to successfully compete with our competitors, our sales will suffer and as a result, our financial condition will be adversely impacted.

We are dependent on the continued services and performance of a concentrated and limited group of senior management and other key personnel, the loss of any of whom could adversely impact our business.

Our future success depends in large part on the continued contributions of a concentrated and limited group of senior management and other key personnel. Beginning in 2021, we outsourced substantially all of our manufacturing work to third parties. As of December 31, 2024, our worldwide employee headcount was 131 employees.

Due to the small size of our Company and our limited number of employees, each member of our executives, managers and other key personnel serves a critical role to our success. If we are unable to retain sufficiently experienced and capable employees, including those who can help us increase revenues generated from our end market segments, our business and financial results may suffer. The loss of the services of any additional executives, managers or other key personnel could impede the achievement of our strategic objectives, seriously harm our ability to successfully implement our business strategy and adversely impact our operating results. In addition, if additional executives, managers or other key personnel resign, retire or are terminated, or their service is otherwise interrupted, including due to global pandemics, we may not be able to replace them in a timely manner and we could experience significant declines in productivity and/or errors due to insufficient staffing or managerial oversight. Moreover, experienced and capable employees in the technology industry remain in high demand, and there is continual competition for their talents. Given our size, we may be at a disadvantage, relative to our larger competitors, in the competition for these personnel.

We rely on our channel partners to generate a substantial amount of our revenue. If we are unable to maintain successful relationships with channel partners, our business, operating results, and financial condition could be adversely affected.

In the years ended December 31, 2024 and 2023, approximately 62% and 35% of our revenues, respectively, were derived from the three largest U.S. wireless carriers, our channel partners. Our channel partners are primarily wireless carriers who sell our products through their sales channels. To the extent our channel partners are unsuccessful in selling or do not promote our products, or we are unable to obtain and retain a sufficient number of high-quality channel partners, our business and operating results could be significantly harmed.

We enter into master sales arrangements with the majority of our channel partners. Under the master sales arrangements, our partners purchase our products for distribution on a purchase order basis. While these arrangements are typically long-term, they generally do not contain any firm purchase volume commitments. As a result, our channel partners are not contractually obligated to purchase from us any minimum quantity of products. We are generally required to satisfy any and all purchase orders delivered to us within specified delivery windows, with limited exceptions (such as orders significantly in excess of forecasts). If we are unable to efficiently manage our supply and satisfy purchase orders on a timely basis to our channel partners, we may be in breach of our sales arrangements and lose potential sales. Our sales arrangements also generally include technical performance standards for our mobile phones, mobile hotspots, and accessories sold, which vary by channel partner. If a technical issue with any of our covered products exceeds certain preset failure thresholds for the relevant performance standard or standards, the channel partner typically has the right to cease selling the product, cancel open purchase orders, and levy certain monetary penalties. If our products suffer technical issues or failures following sales to our channel partners, we may be subject to significant monetary impact and our channel partners may cease making purchase orders, which would significantly harm our business and results of operations. In addition, our channel partners retain sole discretion in which of their stocked products to offer their customers. While we may offer limited customer incentives, we generally have limited to no control over which products our channel partners decide to offer or promote, which directly impacts the number of products that our partners will purchase from us.

Our channel partners may be unsuccessful in marketing, selling and supporting our solutions. They may also market, sell and support solutions that are competitive with ours, and may devote more resources to the marketing, sales, and support of such products. They may have incentives to promote our competitors’ products in lieu of our products, particularly for competitors who do a large volume of business with the channel partner. In the event there is not sufficient demand for our products, our channel partners may stop selling our products completely. While we employ a small direct sales force, our channel partners have significantly larger sales teams who are not contractually obligated to promote any of our devices and often have multiple competing devices in stock to offer their customers. In addition, downstream sales by our channel partners often succeed due to attractive device prices and monthly rate plans, which we do not control. In certain cases, we may promote our own devices through customer incentives, typically in exchange for retail price reductions or contributions of funds for marketing purposes; however, there can be no assurance that any such incentives would contribute to increased purchases of our products. Further, given the impact of attractive pricing on ultimate sales, we generally must offer increased promotional funding or price reductions for our more expensive products. This promotional funding or price reductions operate to reduce our margins and significantly impact our profitability.

New sales channel partners, as well as sales of new products being sold by existing channel partners, may take several months or more to achieve significant sales. Our channel partner sales structure could subject us to lawsuits, potential liability, and reputational harm if, for example, any of our channel partners misrepresents the functionality of our products or services to their customers or violates laws or our corporate policies. Additionally, some of our master agreements with our wireless carrier customers contain “most favored nation” clauses. These clauses typically provide that if we enter into an agreement with another wireless carrier or customer on more favorable terms, we must offer some of those terms to our existing wireless carrier customers. These provisions may obligate us to provide different, more favorable, terms to our existing wireless carrier customers, which could, if applied, result in lower revenues or otherwise adversely impact our business, financial condition, and results of operations.

If we fail to effectively manage our existing or future sales channel partners, our channel partners fail to promote our products effectively, we are unable to meet our obligations under our sales arrangements or enter into future agreements with wireless carrier customers that have terms that are more favorable to the customer, our business and results of operations would be harmed.

We continue to transform our business. The assumptions underlying these efforts may prove to be inaccurate, or we may fail to achieve the expected benefits from these efforts, and we may have to restructure or transform our business again in the future.

In order to be successful, we must have a competitive business model that brings innovative products and services to market in a timely way. We continue to restructure and transform our business in response to changes in industry and market conditions and to focus on business simplification, quality improvement, reduced direct and indirect costs, and new revenue growth. We must manage the potentially higher growth areas of our business, which entail higher operational and financial risks, as well as the non-core areas, in order for us to achieve improved results. Our assumptions underlying these actions may not be correct, we may be unable to successfully execute these plans, and even if successfully executed, our actions may not be effective or may not lead to the anticipated benefits. As a result, we may determine that further restructuring or business transformation will be needed, which could result in the need to record further special charges such as costs associated with workforce reductions, and we may be unable to maintain or improve our market competitiveness or profitability.

In connection with the transformation of our business, we have made and will continue to make, judgments as to whether we should outsource the development and manufacturing of our products. If any of these providers experience (i) difficulties in obtaining sufficient supplies of components, (ii) component prices significantly exceeding anticipated costs, (iii) an interruption in their operations, or (iv) otherwise suffers capacity constraints, we experience a delay in production and shipping of these products, which would have a negative impact on our revenue. Should there be any disruption in services due to natural disasters, economic or political difficulties, transportation restrictions, acts of terror, quarantines, or other restrictions associated with infectious diseases, or other similar events, or any other reason, such disruption could have a material adverse effect on our business. Operating in the international outsourcing environment exposes us to certain inherent risks, including unexpected changes in regulatory requirements and tariffs, and potentially adverse tax consequences, which could materially affect our results of operations. If these providers are unable to achieve greater operational efficiencies, delivery schedules for new product development and current product delivery could be negatively impacted. Currently, we have no second source of manufacturing for a portion of our products. In addition, switching from one provider to another is an expensive, difficult, and time-consuming process, with serious risks to our ability to successfully transfer our development and/or manufacturing operations. If overall demand for our devices increases in the future, we will need to expand our manufacturing capacity in a cost-efficient manner. Our operations, and consequently our revenues and profitability, could be materially adversely affected if we are forced to switch from any of our providers to another provider due to any of a number of factors, including financial difficulties faced by the manufacturer, disagreements in pricing negotiations between us and the manufacturer or organizational changes in the manufacturer.

Further, we have made and will continue to make judgments as to whether we should further reduce, relocate, or otherwise change our workforce. We have outsourced substantially all of our manufacturing functions, software development, and quality control functions to third parties, transferring the employees who previously performed this work. These reductions may have resulted in the loss of institutional knowledge and expertise and the reallocation and combination of certain roles and responsibilities across the organization, all of which could adversely affect our operations. These restructuring and additional measures we might take to reduce costs could divert management attention, yield attrition beyond our intended reduction in force, reduce employee morale, or cause us to delay, limit, reduce, or eliminate certain product development plans, each of which could have an adverse impact on our business, operating results and financial condition. Furthermore, our workforce efforts may impair our ability to achieve our current or future business objectives.

We are materially dependent on the adoption of our solutions by both the industrial enterprise and public sector markets, and if end customers in those markets do not purchase our solutions, our revenues will be adversely impacted, and we may not be able to expand into other markets.

Our revenues have historically been in the industrial enterprise market, and we are materially dependent on the adoption of our solutions by both the industrial enterprise and public sector markets. End customers in the public sector market may remain, for reasons outside our control, tied to solutions or other competitive alternatives to our phones. Sales of our products to these buyers may also be delayed or limited by these competitive conditions. If our products are not widely accepted by buyers in those markets, we may not be able to expand sales of our products into new markets, and our business, results of operations, and financial condition may be adversely impacted.

We rely primarily on third-party contract manufacturers and partners. If these relationships are disrupted and we are unable to obtain substitute manufacturers or partners, on favorable terms or at all, our business, operating results, and financial condition may be harmed.

We have outsourced contract manufacturing, product assembly, and some of our software development operations to third parties located in Asia.

Our contract manufacturers now produce all of our products in facilities located in Asia. All manufacturing of our products is performed in accordance with detailed specifications and product designs furnished or approved by us and is subject to rigorous quality control standards. We periodically review our product manufacturing operations and consider changes we believe may be necessary or appropriate. Although we intend to closely manage the transition process when manufacturing changes, we could experience disruption to our operations during any such transition. Other significant risks include limited control over assembly and testing capacity, delivery schedules, quality assurance, manufacturing yields, production costs, tariffs, and uncertainty over political unrest. Any such disruption could negatively affect our reputation and our operating results. Additionally, our reliance on third parties could, in certain instances, result in reputational damage or even disqualify us from sales opportunities with certain customers.

In addition, we rely on third parties to provide certain services to us, or to our customers, including hosting services, and providers of other cloud-based services. If these third-party providers do not perform as expected, our customers may be adversely affected, resulting in potential liability and negative exposure for us. If it is necessary to migrate these services to other providers due to poor performance, cyber breaches or other security considerations, or other financial or operational factors, it could result in service disruptions to our customers and significant time and expense to us, any of which could adversely affect our business, operating results, and financial condition.

Migrating our design methodology to third-party contract manufacturers or partners could involve increased costs, resources, and development time, and could expose us to further risk of losing control over our intellectual property and the quality of our products.

We have engaged in related-party transactions and may continue to rely on related parties for key business activities, which could create conflicts of interest and adversely affect our business.

We have entered into, and may continue to enter into, transactions with affiliates of Jeffrey Wang, a director who beneficially owns approximately 19% of our common stock. These transactions have included, among other things, engineering services related to the development of new products, and we anticipate continued reliance on related parties for these and potentially other key services.

Related-party transactions present potential conflicts of interest that could result in decisions that prioritize the economic interests of certain individuals over those of our company and its stockholders. In the event of a dispute under any related-party agreement, the interests of affiliated parties may not align with ours, and the resolution of such disputes may be less favorable than what we might achieve in an arms-length transaction with an unaffiliated third party. Additionally, our ability to enforce contractual rights against related parties may be constrained by these relationships.

In the past, affiliates of Mr. Wang have attempted to influence our contractual relationships with third parties by exerting pressure on strategic decisions. While such efforts did not alter the views of a majority of our independent directors, similar actions by related parties in the future could disrupt our operations, create uncertainty, or lead to strategic decisions that are not in the best interests of the company or its stockholders.

Furthermore, there is no assurance that we will be able to replace these related-party services on comparable terms if needed. If we are required to seek alternative service providers, we may incur higher costs, delays, or operational inefficiencies, which could materially impact our business, financial condition, and results of operations.

If our products contain defects or errors, we could incur significant unexpected expenses, experience product returns and lost sales, experience product recalls, suffer damage to our brand and reputation, and be subject to product liability or other claims.

We produce highly complex products that incorporate leading-edge technology, including both hardware and software. The industry standards upon which many of our products are based are also complex, experience changes over time, and may be interpreted in different manners. Software often contains defects or programming flaws that can unexpectedly interfere with expected operations. In addition, our products are complex and are designed to be deployed in large quantities across complex and varying networks. Because of the nature of these products, they can only be fully tested when completely deployed in large networks with high amounts of traffic, and there is no assurance that our pre-shipment testing programs will be adequate to detect all defects. As a result, our customers may discover errors or defects in our hardware or software, or our products may not operate as expected. If we are unable to cure a product defect, we could experience damage to our reputation, reduced customer satisfaction, loss of existing customers and failure to attract new customers, failure to achieve market acceptance, reduced sales opportunities, loss of revenue and market share, increased service and warranty costs, diversion of development resources, legal actions by our customers, and increased insurance costs. Defects, integration issues, or other performance problems in our products could also result in damages to our customers, financial or otherwise. Our customers could seek damages for related losses from us, which could seriously harm our business, operations, financial condition, and liquidity. A product liability claim brought against us, even if unsuccessful, would likely be time-consuming and costly. The occurrence of any of these problems would seriously harm our business, operations, financial condition, and liquidity.

Further, errors, defects, or bugs in our solutions could be exploited by hackers or could otherwise result in an actual or perceived breach of our information systems. Alleviating any of these problems could require significant expense and could cause interruptions, delays, or cessation of our product licensing, which would reduce demand for our products and result in a loss of sales, delay in market acceptance, and injure our reputation and could adversely impact our business, results of operations and financial condition.

If our business does not grow as we expect, or if we fail to manage our growth effectively, our operating results and business will suffer.

Our ability to successfully grow our business depends on a number of factors including our ability to:

As usage of our solutions grows, we will need to continue to make investments to develop and implement new or updated solutions, technologies, security features, and cloud-based infrastructure operations. In addition, we will need to appropriately scale our internal business systems and our services organization, including the suppliers of our detection equipment and customer support services, to serve our growing customer base. Any failure of, or delay in, these efforts could impair the performance of our solutions and reduce customer satisfaction. Further, our growth could increase quickly and place a strain on our managerial, operational, financial, and other resources, and our future operating results depend to a large extent on our ability to successfully manage our anticipated expansion and growth. To manage our growth successfully, we will need to continue to invest in sales and marketing, research and development, general and administrative functions, and other areas. We are likely to recognize the costs associated with these investments earlier than receiving some of the anticipated benefits, and the return on these investments may be lower, or may develop more slowly, than we expect, which could adversely impact our operating results.

If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities or develop new solutions or upgrades to our existing solutions, satisfy customer requirements, maintain the quality and security of our solutions, or execute our business plan, any of which could harm our business, operating results and financial condition.

We are required to undergo a lengthy customization and certification process for each wireless carrier customer, which increases our operating expenses and cost of revenue, and failure to obtain such certification would adversely impact our results of operations and financial condition.

Each wireless carrier requires each of our devices to complete a thorough technical acceptance process before it can be stocked and sold. Such acceptance processes impose rigorous and complex requirements on our devices, which result in a lengthy testing and certification process, during which we incur substantial operating expenses related to the wireless carrier’s technical acceptance of our devices. The acceptance processes and related costs to us vary across carrier customers depending on carrier size and level of customization required. Generally, the certification process commences within one to three months of product concept development. During this development stage, certain carriers provide a technology roadmap and target demographics, allowing us to define product specifications to meet carrier goals, while other carriers provide defined specifications and preferred price points. Once we receive approval of a product concept by the carrier, we and the carrier advance the product to the development stage. When the product is close to becoming a functioning model, we commence internal quality assurance processes and field testing, which may include third-party lab testing, in-market field testing, and interoperability testing. Finally, as the last step in the testing phase, the wireless carrier typically conducts testing itself, following which the product may be certified and stocked. The entire process can last from 6 to 18 months depending on the particular wireless carrier and type of device. Any delay in the acceptance process or failure to satisfy the device certification requirements affects our ability to bring products to market and adversely impacts our results of operations and financial condition.

We experience lengthy sales cycles for our products and the delay of an expected large order could result in a significant unexpected revenue shortfall.

The purchase of our products is often an enterprise-wide decision for prospective customers, which requires us to engage in sales efforts over an extended period of time and provide a significant level of education to prospective customers regarding the uses and benefits of such devices. Prospective customers, especially the wireless carriers that sell our products, often undertake a prolonged evaluation process that may take from several months to several years in certain cases. Consequently, if our forecasted sales from a specific customer are not realized, we may not be able to generate revenues from alternative sources in time to compensate for the shortfall. The loss or delay of an expected large order could also result in a significant unexpected revenue shortfall. Moreover, to the extent we enter into and deliver our products pursuant to significant contracts earlier than we expected, our operating results for subsequent periods may fall below expectations. We may spend substantial time, effort, and money on our sales and marketing efforts without any assurance that our efforts will produce any sales. If we are unable to succeed in closing sales with new and existing customers, our business, operating results, and financial condition will be harmed.

If we fail to adequately forecast demand for our inventory and supply needs, we could incur additional costs or experience manufacturing delays, which could reduce our gross margin or cause us to delay or even lose sales.

Because our production volumes are based on a forecast of channel partner demand rather than firm purchase commitments from our major customers, our forecasts have been, and there is a risk that our forecasts could be inaccurate in the future. There is a risk that we will be unable to sell our products at the volumes and prices we expect, which may result in excess inventory. We provide, and will continue to provide, forecasts of our demand to our third-party suppliers prior to the scheduled delivery of products to our channel partners. If we overestimate our requirements, our contract manufacturers may have excess component inventory, which could increase our costs. If we underestimate our requirements, our contract manufacturers may have inadequate component inventory, which could interrupt the manufacturing of our products and result in delays in shipments and revenues, lost sales, or we could incur unplanned overtime costs to meet our requirements, resulting in significant cost increases. For example, certain materials and components used to manufacture our products may reach end of life during any of our product’s life cycles, following which suppliers no longer provide such expired materials and components. This would require us to either source and qualify an alternative component, which could require a re-certification of the device by the wireless carriers and/or regulatory agencies or forecast product demand for a final purchase of such materials and components that may reach end of life to ensure that we have sufficient product inventory through a product’s life cycle. If we overestimate forecasted demand, we will hold excess end-of-life materials and components resulting in increased costs. If we underestimate forecasted demand, we could experience delays in shipments and loss of revenues.

In addition, if we underestimate our requirements and the applicable supplier becomes insolvent or is no longer able to timely supply our needs in a cost-efficient manner or at all, we may be required to acquire components, which may need to be customized for our products, from alternative suppliers, including at significantly higher costs. For example, in 2018, one of our suppliers became insolvent and ceased all production, requiring us to seek alternative supply of complex components in a very short time frame. If we cannot source alternative suppliers and/or alternative components, we may suffer delays in shipments or lost sales. Similarly, credit constraints at our suppliers could require us to accelerate payment of our accounts payable, impacting our cash flow. Further, lead times for materials and components that we order vary significantly and depend on factors such as the specific supplier, contract terms, customization needed for any particular component and demand for each component at a given time. Any such failure to accurately forecast demand and manufacturing and supply requirements, and any need to obtain alternative supply sources, could materially harm our business, results of operations, and financial condition.

The markets for our mobile devices and related accessories may not develop as quickly as we expect or may not develop at all.

Our future success is substantially dependent upon continued adoption of devices and related accessories in the industrial enterprise and public sector markets, including the transition from LMR and PTT to smartphone and cellular networks. These market developments and transitions may take longer than we expect or may not occur at all and may not be as widespread as we expect. If the market does not develop as we expect, our business, operating results, and financial condition will be significantly harmed.

Our dependence on third-party suppliers for key components of our products could delay shipment of our products and reduce our sales.

We depend on certain suppliers for the delivery of components used in the assembly of our products, including machined parts, injection molded plastic parts, printed circuit boards, and other miscellaneous custom parts for our products. Our reliance on third-party suppliers creates risks related to our potential inability to obtain an adequate supply of components and reduced control over pricing and timing of delivery of components. In particular, we have little to no control over the prices at which our suppliers sell materials and components to us. The components business has, from time to time, experienced periods of extreme shortages in product supply, generally as the result of demand exceeding available supply. Many companies use the same raw materials and supplies that we do in the production of their products. Companies with more resources than our own may have a competitive advantage in obtaining raw materials and supplies due to greater buying power. When these shortages occur, suppliers also tend to either increase prices or reduce the number of units sold to customers. In addition, certain supplies of our components are available only from a single source or limited sources and we may not be able to diversify suppliers in a timely manner. We have experienced shortages in the past that have negatively impacted our results of operations and may experience such shortages in the future. These factors can result in reduced supply, higher prices of components used in the assembly of our products, and delays in the receipt of certain of our key components, which in turn may generate increased costs, lower margins, and delays in product delivery, with a corresponding adverse effect on revenues and customer relationships. For example, we phased out low margin white label products in the first half of 2024 because our manufacturing partners had difficulty maintaining production of our white label products.

We also do not have long-term supply agreements with any of our suppliers. Our current contracts with certain suppliers may be canceled or not extended by such suppliers and, therefore, do not afford us sufficient protection against a reduction or interruption in supplies. Moreover, if any of these suppliers breach their contracts with us, our legal remedies associated with such a breach may be insufficient to compensate us for any damages we may suffer.

Any interruption of supply for any material components of our products for any reason, including but not limited to global or local health crises, or inability to obtain required components from our third-party suppliers, could significantly delay the production and shipment of our products and harm our revenues, profitability and financial condition.

Our future success is dependent on our ability to create independent brand awareness for our company and products with end customers, and our inability to achieve such brand awareness could limit our prospects.

We depend on a small number of wireless carriers to distribute our products. While we intend to accelerate direct marketing and end-customer brand awareness initiatives in the future, our sales and marketing efforts have historically been predominantly focused on channel partners. As such, historically, our operating expenses related to end-customer marketing efforts have historically been very small, representing less than 1.0% of our total sales and marketing expenses (including during the years ended December 31, 2024 and 2023). Increasing end-customer brand awareness requires investment in our sales and marketing efforts. As a result, we expect our sales and marketing expenses to increase in the future, primarily from increased use of third-party service providers, which will require us to cost-efficiently ramp up our sales and marketing capabilities and effectively target end customers. However, there can be no assurance that we will successfully increase our brand awareness or do so in a cost-efficient manner while maintaining market share within our existing sales channels. Our failure to establish stand-alone brand awareness with end customers of our products would leave us vulnerable to competitors and have an adverse impact on our prospects. If we are unable to significantly increase the awareness of our brand and solutions with end customers in a cost-efficient manner, we will remain significantly dependent on our channel partners for sales of our products and would adversely impact our ability to grow our business.

If we are unable to sell our solutions into new markets, our revenues may not grow.

Any new market into which we attempt to sell our solutions may not be receptive. Our ability to penetrate new markets depends on the quality of our solutions, the continued adoption of our public safety solution by first responders, the perceived value of our solutions as a risk management tool and our ability to design our solutions to meet the demands of our customers. If the markets for our solutions do not develop as we expect, our revenues may not grow.

Our ability to successfully face these challenges depends on several factors, including increasing the awareness of our solutions and their benefits, the effectiveness of our marketing programs, the costs of our solutions, our ability to attract, retain and effectively train sales and marketing personnel, and our ability to develop relationships with wireless carriers and other partners. If we are unsuccessful in developing and marketing our solutions into new markets, new markets for our solutions might not develop or might develop more slowly than we expect, either of which would harm our revenues and growth prospects.

Changes in the availability of federal funding to support local public safety or other public sector efforts could impact our opportunities with public sector end customers.

Many of our public sector end customers rely to some extent on funds from the U.S. federal government to purchase and pay for our solutions. Any reduction in federal funding for local public safety or other public sector efforts could result in our end customers having less access to funds required to continue, renew, expand, or pay for our solutions. If federal funding is reduced or eliminated and our end customers cannot find alternative sources of funding to purchase our solutions, our business will be harmed.

Failure of our suppliers, subcontractors, distributors, resellers, and representatives to use acceptable legal or ethical business practices, or to fail for any other reason, could negatively impact our business.

We do not control the labor and other business practices of our suppliers, subcontractors, distributors, resellers, and third-party sales representatives (the “TPSRs”), and cannot provide assurance that they will operate in compliance with applicable rules, and regulations regarding working conditions, employment practices, environmental compliance, anti-corruption, and trademark a copyright and patent licensing. If one of our suppliers, subcontractors, distributors, resellers, or TPSRs violates labor or other laws or implements labor or other business practices that are regarded as unethical, the shipment of finished products to us could be interrupted, orders could be canceled, relationships could be terminated, and our reputation could be damaged. If one of our suppliers or subcontractors fails to procure the necessary license rights to trademarks, copyrights, or patents, legal action could be taken against us that could impact the salability of our products and expose us to financial obligations to a third party. Any of these events could have a negative impact on our sales and results of operations.

Moreover, any failure of our suppliers, subcontractors, distributors, resellers, and TPSRs, for any reason, including bankruptcy or other business disruption, could disrupt our supply or distribution efforts and could have a negative impact on our sales and results of operations.

We are exposed to risks associated with strategic transactions.

We may pursue mergers, acquisitions, or dispositions of businesses or assets or other strategic transactions that we believe will strengthen, streamline, or expand our business. Each such transaction would be dependent upon several factors, including identifying suitable companies, businesses, or assets that align with our business strategies, reaching an agreement with the potential counterparties on acceptable terms, receipt of any applicable regulatory and other approvals, and other conditions. These transactions involve various risks, including among others:

Risks Related to Our Financial Condition

We may not generate sufficient liquidity to operate our business and maintain its growth.

We will require significant funds to implement our business strategy, upgrade and expand our product portfolio, and meet our other liquidity needs. Our historical revenue is not indicative of our future performance. There can be no assurance that we will generate sufficient revenue to offset the cost of maintaining our operations, including significant accounting, legal, administrative, and other costs associated with being a public company, and successfully expand our business in accordance with our growth strategy. Additionally, our cash needs may increase in the near future as we focus on growing and developing our data devices businesses and expanding our operations internationally, and our liquidity may not be sufficient to achieve these objectives.

We may need to seek to raise additional capital from the sale of securities or the incurrence of indebtedness to allow us to maintain our operations and invest in growth opportunities. There can be no assurance that any debt or equity financing will be available to us on acceptable terms, or at all. Additionally, if we issue additional equity securities to raise funds, whether to existing investors or others, the ownership percentage of our existing stockholders would be reduced. New investors may demand rights, preferences, or privileges senior to those of existing holders of common stock. We may also be limited as to the amount of funds we can raise pursuant to SEC rules and the continued listing requirements of Nasdaq.

An inability to maintain adequate cash on hand, generate sufficient cash flow from our operations, or access capital financing on acceptable terms will reduce our chances to compete successfully and expand our business in the manner currently contemplated and adversely affect our business and results of operations.

We have not been profitable in recent years and may not achieve or maintain profitability in the future.

We have incurred significant net losses since 2013 and have an accumulated deficit of $284 million as of December 31, 2024. We are not certain whether or when we will obtain a high enough volume of sales of our products to sustain or increase our growth or achieve or maintain profitability in the future. We also expect our costs to increase in future periods, which would negatively impact our future operating results if our revenues do not increase. In particular, we expect to continue to expend substantial financial and other resources on:

These investments may not result in increased revenues or growth in our business. Additionally, we have recently and may continue to encounter unforeseen operating expenses, difficulties, complications, delays, and other unknown factors that may result in losses in future periods. If we are unable to increase our revenues at a rate sufficient to offset the expected increase in our costs, our business, operating results, and financial position may be harmed, and we may not be able to achieve or maintain profitability over the long term. We are subject to the risks and uncertainties associated with the development and release of new products. Our principal sources of liquidity as of December 31, 2024, consist of existing cash and cash equivalents totaling $5.3 million. The cost structure of the company has been significantly reduced and many aspects of product development and operational support have been outsourced to add additional spending flexibility if needed. We have subsequently raised approximately $3.8 million through our ATM stock sale program and $3.0 million from a debt facility. Our existing capital is expected to allow the company to continue operations for at least the next twelve months. If necessary, we will seek to raise additional capital. There can be no assurance that additional financing will be available to us on acceptable terms, or at all. Additionally, if we issue additional equity securities to raise funds, whether to existing investors or others, the ownership percentage of our existing stockholders would be reduced. New investors may demand rights, preferences, or privileges senior to those of existing holders of common stock. Additionally, we may be limited as to the amount of funds we can raise pursuant to SEC rules and the continued listing requirements of the Nasdaq Stock Market or Nasdaq. If we cannot grow our revenue run-rate or raise needed funds, we might be forced to make additional reductions in our operating expenses, which could adversely affect our ability to implement our business plan and ultimately our viability as a Company.

Our ability to use our net operating losses to offset future taxable income will be subject to certain limitations.

As of December 31, 2024 and 2023, we had U.S. federal and state net operating loss carryforwards, or NOLs, of $120.1 million and $95.2 million, respectively, due to prior period losses, a portion of which expire in various years beginning in 2037 and 2035, respectively, if not utilized. In general, under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its NOLs to offset future taxable income. Due to the investment by AJP Holding Company, LLC (“AJP”) in 2022 and the resulting ownership change, the future use of the NOLs to reduce future taxable income of the Company is severely limited.

Risks Related to Information Technology and Intellectual Property

A security breach or other significant disruption of our IT systems or those of our partners, suppliers, or manufacturers, caused by cyberattacks or other means, could have a negative impact on our operations, sales, and operating results.

We rely extensively on our information systems to manage our business operations. We have experienced and expect to continue to experience attempts to compromise our information technology systems and those of our third-party service providers. All IT systems are potentially vulnerable to damage, unauthorized access, or interruption from a variety of sources, including but not limited to, cyberattacks, cyber intrusions, computer viruses, security breaches, denial-of-service attacks, ransomware or other malware, energy blackouts, natural disasters and severe weather conditions, terrorism, sabotage, war, insider trading, human error, and computer and telecommunication failures. Attacks against the Company can escalate during periods of geopolitical tensions or conflict. Additionally, like other mobile device manufacturers, we use open-source software from time to time, which may be more susceptible to cybersecurity vulnerabilities that may not be identified timely. We are also dependent upon third-party manufacturers and service providers to adequately protect our IT systems. We do not have direct oversight or influence over how third parties manage the security, quality, or resiliency of their networks. Cyber attacks continue to evolve in sophistication and volume, and inherently may be difficult to detect for long periods of time. For example, the development and implementation of AI technologies may further increase our exposure to or exacerbate the risks of cyber attacks or other security incidents, particularly where such technologies are exploited by third parties to breach our IT systems or those of our third-party service providers.

A cyberattack or other significant disruption involving our IT systems or those of our outsource partners, suppliers, or manufacturers could result in the unauthorized release of proprietary, confidential, or sensitive information of ours or result in virus and malware installation on our devices. Such unauthorized access to, or release of, this information or other security breaches could: (i) allow others to unfairly compete with us, (ii) compromise safety or security, (iii) subject us to claims for breach of contract, tort, and other civil claims, and (iv) damage our reputation. We could face regulatory penalties, enforcement actions, remediation obligations, or private litigation by parties whose data is improperly disclosed or misused. Any or all of the foregoing could negatively impact our business, financial condition, and results of operations.

If we are unable to successfully protect our intellectual property, our competitive position may be harmed.

Our ability to compete is heavily affected by our ability to protect our intellectual property. We rely on a combination of patents, patent applications, copyright and trademark laws, trade secrets, confidentiality procedures, and contractual provisions to protect our proprietary rights. We also enter, and plan to continue to enter, into confidentiality, invention assignment, or license agreements with our employees, consultants, and other parties with whom we contract, and control access to and distribution of our software, documentation, and other proprietary information. The steps we take to protect our intellectual property may be inadequate, and it is possible that some or all of our confidentiality agreements will not be honored, and certain contractual provisions may not be enforceable. Existing trade secret, trademark, and copyright laws offer only limited protection. Unauthorized parties may attempt to copy aspects of our products or obtain and use information that we regard as proprietary. Policing unauthorized use of our products is difficult, time-consuming, and costly, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. We cannot assure you that our means of protecting our proprietary rights will be adequate or that our competitors will not independently develop similar technology, the effect of either of which would harm our competitive position in the market. Furthermore, disputes can arise with our strategic partners, customers, or others concerning the ownership of intellectual property.

Others may claim that we infringe on their intellectual property rights, which may result in costly and time-consuming litigation and could delay or otherwise impair the development and commercialization of our products.

In recent years, there has been a significant increase in litigation in the United States involving patents and other intellectual property rights, and because our products are comprised of complex technology, we are often involved in or impacted by assertions, including both requests to take licenses and litigation, regarding infringement of patent and other intellectual property rights of third parties. Third parties have asserted, and in the future may assert, intellectual property infringement claims against us and against our channel partners, end customers, and suppliers. Many of these assertions are brought by non-practicing entities whose principal business model is to secure patent licensing revenues from product manufacturing companies. Claims for alleged infringement and any resulting lawsuit, if successful, could subject us to significant liability for damages and invalidation of our intellectual property rights. Defending any such claims, with or without merit, including pursuant to indemnity obligations, could be time-consuming, and expensive, cause product shipment delays, or require us to enter into a royalty or licensing agreement, any of which could delay the development and commercialization of our products or reduce our margins. If we are unable to obtain a required license, our ability to sell or use certain products may be impaired. In addition, if we fail to obtain a license, or if the terms of the license are burdensome to us, our operations could be significantly harmed.

Our use of open-source software could subject us to possible litigation or otherwise impair the development of our products.

A portion of our technologies incorporates open-source software, including open-source operating systems such as Android, and we expect to continue to incorporate open-source software into our platform in the future. Few of the licenses applicable to open-source software have been interpreted by courts, and their application to the open-source software integrated into our proprietary technology platform may be uncertain. If we fail to comply with these licenses, then pursuant to the terms of these licenses, we may be subject to certain requirements, including requirements that we make available the source code for our software that incorporates the open-source software. We cannot assure you that we have not incorporated open-source software in our software in a manner that is inconsistent with the terms of the applicable licenses or our current policies and procedures. If an author or other third party that distributes such open-source software were to allege that we had not complied with the conditions of one or more of these licenses, we could incur significant legal expenses defending against such allegations. Litigation could be costly for us to defend, have a negative effect on our operating results and financial condition, or require us to devote additional research and development resources to change our technology platform.

With respect to open-source operating systems, if third parties cease continued development of such operating systems or restrict our access to such operating systems, our business and financial results could be adversely impacted. We are dependent on third parties’ continued development of operating systems, software application ecosystem infrastructures, and such third parties’ approval of our implementations of their operating and system and associated applications. If such parties cease to continue development or support of such operating systems or restrict our access to such operating systems, we would be required to change our strategy for our devices. As a result, our financial results could be negatively impacted because a resulting shift away from the operating systems we currently use, and the associated applications ecosystem could be costly and difficult.

Our inability to obtain and maintain any third-party license required to develop new products and product enhancements could seriously harm our business, financial condition, and results of operations.

From time to time, we are required to license technology from third parties to develop new products or product enhancements. For example, we have entered into worldwide intellectual property cross-license agreements or other technology license agreements with a number of global technology companies in the mobile telecommunications market. Third-party licenses may not be available to us on commercially reasonable terms, or at all. If we fail to renew any intellectual property license agreements on commercially reasonable terms, or any such license agreements otherwise expire or terminate, we may not be able to use the patents and technologies of these third parties in our products, which are critical to our success. We cannot assure you that we will be able to effectively control the level of licensing and royalty fees paid to third parties, and a significant increase in such fees could have a significant and adverse impact on our future profitability. Seeking alternative patents and technologies may be difficult and time-consuming, and we may not be successful in finding alternative technologies or incorporating them into our products. Our inability to obtain any third-party license necessary to develop new products or product enhancements could require us to obtain substitute technology of lower quality or performance standards, or at greater cost, which could seriously harm our business, financial condition, and results of operations.

Increasing regulatory focus on privacy and cybersecurity issues and expanding laws could expose us to liability, subject us to lawsuits, investigations, and other liabilities and restrictions on our operations that could significantly and adversely affect our business.

Personal privacy and information security are significant issues in the United States, Europe and the other jurisdictions in which we operate or make our products and applications available. The legislative and regulatory framework for privacy and security issues worldwide is rapidly evolving and may be inconsistent from jurisdiction to jurisdiction. Examples of these laws include but are not limited to:

We may incur substantial expense in complying with the obligations imposed by various jurisdictions in which we do business or seek to do business and we may be required to make significant changes in our business operations, all of which may adversely impact our revenues and our business overall. Additionally, our failure or perceived failure to comply with privacy and information security laws and regulations would result in negative publicity fines and orders requiring that we change our practices, which will adversely affect our business, reputation, financial condition, and operating results.

Risks Related to Legal and Regulatory Matters

Changes in laws and regulations concerning the use of telecommunication bandwidth could increase our costs and adversely impact our business.

Our business depends on our ability to sell devices that use telecommunication bandwidth allocated to licensed and unlicensed wireless services, and that use of that bandwidth is subject to laws and regulations that are subject to change over time. Changes in the permitted uses of telecommunication bandwidth, reallocation of such bandwidth to different uses, and new or increased regulation of the capabilities, manufacture, importation, and use of devices that depend on such bandwidth could increase our costs, require costly modifications to our products before they are sold, or limit our ability to sell those products into our target markets. In addition, we are subject to regulatory requirements for certification and testing of our products before they can be marketed or sold. Those requirements may be onerous and expensive. Changes to those requirements could result in significant additional costs and could adversely impact our ability to bring new products to market in a timely fashion.

The interpretation and implementation of the various provisions of the Communications Act of 1934, as amended, and the FCC rules implementing said act continue to be heavily debated and may have a material adverse effect on our business. FCC regulatory activity has increased in 2023 and 2024, particularly in connection with broadband the origin of hardware (including chipsets) and software used in telecommunication and data devices. We cannot predict how increased regulatory activity at the FCC will impact our businesses but expect increased legal and compliance costs. If we do not comply with FCC rules, regulations, orders, policies, or procedures we could be subject to FCC enforcement actions, fines, and possibly restrictions on our ability to operate or offer certain or all of our products in the United States. Any enforcement action by the FCC, which may be a public process, would hurt our reputation in the industry, could erode customer trust, possibly impair our ability to sell our products to customers, and could adversely affect our business, results of operations, and financial condition.

Changes in U.S. trade policy, including the imposition of tariffs and restrictions and the resulting consequences, may have a material adverse impact on our business, operating results, and financial condition.

We cannot predict what changes to trade policy will be made, or the economic impact that changes to trade policy will have, including significant increases in tariffs on goods imported into the United States, particularly tariffs on products manufactured abroad, including China and other countries, and the length of time such tariffs may remain in place, or whether the entry into new bilateral or multilateral trade agreements will occur. As of the filing date of this prospectus, the U.S. has imposed tariffs on foreign imports into the United States, including, most relevant to us, an additional 145% tariff on all imports from China, provided, that an exemption was granted to smartphones and certain other items. These tariffs may further increase the cost of our products and could negatively impact our results of operations. At this time, it remains unclear what additional actions, if any, will be taken by the U.S. or other governments with respect to international trade agreements, the imposition of additional tariffs on goods imported into the U.S., tax policy related to international commerce, increased export control, sanctions and investment restrictions, or other trade matters. Although the ultimate scope and timing of any such actions is currently indeterminable, if implemented, they could have a material impact on our financial condition and results of operations. If further tariffs are imposed on a broader range of imports, further retaliatory trade measures are taken by various countries in response to tariffs, or efforts are made to withdraw from or substantially modify such agreements, then we may be required to raise our prices or incur additional expenses.

In addition, the FCC rules prohibit communications equipment deemed to pose an unacceptable risk to national security from obtaining the equipment authorization that allows the products to be imported, marketed, or sold in the U.S. If any of our product components were to be classified under these restrictions, we could face regulatory hurdles, supply chain disruptions, and lost revenue opportunities, which could have a material impact on our operations and financial results. Additionally, evolving national security policies and heightened scrutiny of foreign-manufactured telecommunications equipment may further increase compliance costs and restrict our market access.

The adoption or expansion of trade restrictions, the escalation of a trade war, or other governmental actions related to tariffs, trade agreements, or prohibition of components of communication equipment, could negatively impact demand for our products, increase costs, disrupt our supply chain, and adversely affect our customers and suppliers. Any of these developments could have a material adverse effect on our business, operating results, and financial condition.

The unfavorable outcome of any future litigation, arbitration, or administrative action could have a significant adverse impact on our financial condition or results of operations.

From time to time, we are a party to litigation, arbitration, or administrative actions. Our business may bring us into conflict with third parties with whom we have contractual or other business relationships, or with our competitors or others whose interests differ from ours. If we are unable to resolve those conflicts on terms that are satisfactory to all parties, we may become involved in litigation brought by or against us. Our financial results and reputation could be negatively impacted by unfavorable outcomes to any future litigation or administrative actions, including those related to the Foreign Corrupt Practices Act, the U.K. Bribery Act, or other anti-corruption laws. Monitoring, initiating, and defending against legal actions is time-consuming for our management, likely to be expensive, and may detract from our ability to fully focus our internal resources on our business activities. In addition, despite the availability of insurance, we may incur substantial legal fees and costs in connection with litigation. Lawsuits are subject to inherent uncertainties, and defense and disposition costs depend upon many unknown factors. Lawsuits could result in judgments against us that require us to pay damages, enjoin us from certain activities, or otherwise negatively affect our legal or contractual rights, which could have a significant adverse effect on our business. In addition, the inherent uncertainty of such litigation could lead to increased volatility in our stock price and a decrease in the value of our stockholders’ investment in our common stock. There can be no assurances as to the favorable outcome of any litigation or administrative proceedings. In addition, it can be very costly to defend litigation or administrative proceedings and these costs could negatively impact our financial results.

We may incur substantial costs and receive adverse outcomes in litigation, regulatory investigations, and other legal matters in connection with alleged violations of securities laws and regulations.

Our business, financial condition, and results of operations could be materially adversely affected by unfavorable results in pending or future litigations, regulatory investigations, and other legal matters related to violations or perceived violations of applicable securities laws and regulations by the Company or its affiliates.

We have been subject to the SEC investigation and stockholders’ class actions in the past and may become subject to securities-related investigations or legal proceedings in the future. The ultimate resolution of such investigations and lawsuits cannot be predicted, and the claims raised in these lawsuits may result in further legal matters or actions against us, including, but not limited to, government enforcement actions or additional private litigation. We were subject to an SEC investigation that had started in March 2020. Although there were no penalties imposed against the Company as a result of that SEC investigation, we cannot predict the outcome of any particular proceeding, or whether any new SEC investigation will be resolved favorably or ultimately result in charges or material damages, fines, or other penalties, enforcement actions, or civil or criminal proceedings against us or members of our senior management.

Litigation matters and regulatory investigations, regardless of their merits or their ultimate outcomes, are costly, divert management’s attention, and may materially adversely affect our reputation and demand for our products. We cannot predict with certainty the eventual outcome of pending or future legal matters. An adverse outcome of litigation or legal matters could result in us being responsible for significant damages. Any of these negative effects resulting from litigation, regulatory investigations, and other legal matters could materially adversely affect our business, financial condition, and results of operations.

We are subject to anti-corruption, anti-bribery, anti-money laundering, economic sanctions, export control, and similar laws. Non-compliance with such laws can subject us to criminal or civil liability and harm our business, revenues, financial condition, and results of operations.

We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, and other anti-bribery and anti-money laundering laws in the countries in which we conduct activities. Anti-corruption and anti-bribery laws have been enforced aggressively in recent years and are interpreted broadly to generally prohibit companies and their employees and third-party intermediaries from authorizing, offering, or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. As we increase our international presence, we may engage with distributors and third-party intermediaries to market our solutions and to obtain necessary permits, licenses, and other regulatory approvals. In addition, we or our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners, and agents, even if we do not explicitly authorize such activities.

The United States has imposed economic sanctions that affect transactions with designated foreign countries, nationals and others. In particular, the United States prohibits U.S. persons from engaging with individuals and entities identified as “Specially Designated Nationals,” such as terrorists and narcotics traffickers. These prohibitions are administered by the U.S. Department of the Treasury’s Office of Foreign Assets Control, or OFAC. OFAC rules prohibit U.S. persons from engaging in, or facilitating a foreign person’s engagement in, transactions with or relating to the prohibited individual, entity or country, and require the blocking of assets in which the individual, entity or country has an interest. Blocked assets (e.g., property or bank deposits) cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. Other countries in which we operate, including Canada and the United Kingdom, also maintain economic and financial sanctions regimes.

Some of our solutions, including software updates and third-party accessories, may be subject to U.S. export control laws, including the Export Administration Regulations; however, the vast majority of our products are non-U.S.-origin items , developed and manufactured outside of the United States, and therefore not subject to these laws. For third-party accessories, we rely on manufacturers to supply the appropriate export control classification numbers that determine our obligations under these laws.

We cannot assure you that our employees and agents will not take actions in violation of our policies and applicable law, for which we may be ultimately held responsible. As we increase our international presence, our risks under these laws, rules, and regulations may increase. Further, any change in the applicability or enforcement of these laws, rules, and regulations could adversely impact our business operations and financial results.

Detecting, investigating and resolving actual or alleged violations can require a significant diversion of time, resources, and attention from senior management. In addition, noncompliance with anti-corruption, anti-bribery, anti-money laundering, or economic sanctions laws, rules, and regulations could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension and/or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage, and other collateral consequences. If any subpoenas or investigations are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, revenues, financial condition, and results of operations would be significantly harmed. In addition, responding to any action will likely result in a significant diversion of management’s attention and resources and significant defense costs and other professional fees. Enforcement actions and sanctions could further harm our business, financial condition and results of operations.

We are subject to a wide range of product-, consumer-, worker- safety and environmental laws and regulations.

Our operations and the products we manufacture or sell are subject to a wide range of product regulatory and safety, consumer, worker safety and environmental laws and regulations. Compliance with such existing or future laws and regulations could subject us to future costs or liabilities, impact our production capabilities, constrict our ability to sell, expand or acquire facilities, restrict what solutions we can offer and generally impact our financial performance. Our products are designed for use in potentially explosive or hazardous environments. If our product design fails for any reason in such environments, we may be subject to product liabilities and future costs. In addition, some of these laws are environmental and relate to the use, disposal, remediation, emission, discharge of and exposure to hazardous substances. These laws often impose liability and can require parties to fund remedial studies or actions regardless of fault. Environmental laws have tended to become more stringent over time and any new obligations under these laws could have a negative impact on our operations or financial performance.

Laws focused on the energy efficiency of electronic products and accessories, recycling of both electronic products and packaging, reducing or eliminating certain hazardous substances in electronic products, and the transportation of batteries continue to expand significantly. Laws pertaining to accessibility features of electronic products, standardization of connectors and power supplies, the transportation of lithium-ion batteries, and other aspects are also proliferating. There are also demanding and rapidly changing laws around the globe related to issues such as product safety, radio interference, radio frequency radiation exposure, medical related functionality, and consumer and social mandates pertaining to use of wireless or electronic equipment. These laws, and changes to these laws, could have a substantial impact on whether we can offer certain products, solutions, and services, and on what capabilities and characteristics our products or services can or must include.

These laws and regulations impact our products and could negatively impact our ability to manufacture and sell products competitively. In addition, we anticipate that we will see increased demand to meet voluntary criteria related to reduction or elimination of certain constituents from products, increasing energy efficiency and providing additional accessibility.

The requirements of being a public company may strain our resources and distract our management, which could make it difficult to manage our business.

We are required to comply with various regulatory and reporting requirements, including those required by the SEC. Complying with these reporting and other regulatory requirements will be time-consuming and will result in increased costs to us and could have a negative effect on our results of operations, financial condition or business.

As a public company, we are subject to the reporting requirements of the Exchange Act and requirements of the Sarbanes-Oxley Act. These requirements may place a strain on our systems and resources. The Exchange Act requires that we file annual, quarterly and current reports with respect to our business and financial condition. The Sarbanes-Oxley Act requires that we attest to having internal controls over financial reporting. To maintain and improve the effectiveness of our disclosure controls and procedures, we will need to commit significant resources, hire additional staff and provide additional management oversight. We will be implementing additional procedures and processes for the purpose of addressing the standards and requirements applicable to public companies. Sustaining our growth also will require us to commit additional management, operational and financial resources to identify new professionals to join our firm and to maintain appropriate operational and financial systems to adequately support expansion. These activities may divert management’s attention from other business concerns, which could have a significant adverse impact on our results of operations, financial condition or business.

Being a public company requires significant resources and management oversight. As a result, management’s attention may be diverted from other business concerns, which could harm our business, operating results, and financial condition.

Risks Related to this Offering and Ownership of Our Common Stock

This is a best-efforts offering, no minimum amount of securities is required to be sold, and we may not raise the amount of capital we believe is required for our business plans, including our near-term business plans.

The placement agent has agreed to use its reasonable best efforts to solicit offers to purchase the securities in this offering. The placement agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, placement agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth herein. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to support our continued operations, including our near-term continued operations. Thus, we may not raise the amount of capital we believe is required for our operations in the short-term and may need to raise additional funds to complete such short-term operations. Such additional fundraises may not be available or available on terms acceptable to us.

Holders of our pre-funded warrants will have no rights as a common stockholder until they acquire our common stock.

Until you acquire shares of our common stock upon exercise of your pre-funded warrants, you will have no rights with respect to shares of our common stock issuable upon exercise of your pre-funded warrants. Upon exercise of your pre-funded warrants, you will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

There is no public market for the pre-funded warrants being offered in this offering.

There is no established public trading market for the pre-funded warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the pre-funded warrants on any national securities exchange or other nationally recognized trading system, including The Nasdaq Capital Market. Without an active trading market, the liquidity of the warrants and pre-funded warrants will be limited.

If you purchase shares of our common stock sold in this offering, you will experience immediate and substantial dilution in the net tangible book value of your shares. In addition, we may issue equity or convertible debt securities in the future, which may result in additional dilution to investors.

Investors purchasing our common stock in this offering will pay a price per share that substantially exceeds the as adjusted net tangible book value per share. As a result, investors purchasing our common stock in this offering will incur immediate dilution of $0.85 per share, representing the difference between the assumed public offering price of $1.45 per share, which is the last reported sale price of our common stock on the Nasdaq on June 18, 2025, and our as adjusted net tangible book value as of March 31, 2025. For more information on the dilution you may suffer as a result of investing in this offering, see the section titled “Dilution” below. In addition, to the extent we need to raise additional capital in the future and we issue shares of common stock or securities convertible or exchangeable for our common stock, our then-existing stockholders may experience dilution and the new securities may have rights senior to those of our common stock offered in this offering.

Certain of our affiliates and significant stockholders are not subject to lock-up or standstill agreements and may sell shares at any time, which could adversely affect the trading price of our common stock and our ability to raise capital.

While most of our officers and directors are subject to lock-up agreements restricting the transfer of their shares following the consummation of this offering, subject to customary exceptions, several of our significant stockholders are not subject to any similar contractual restrictions. Mr. Jeffrey Wang, AJP, the Orbic Group, and Laurence W. Lytton are not subject to any lockup or standstill agreement or other obligation to maintain their ownership of our shares. Subject to restrictions on the resale of our shares applicable to those stockholders pursuant to our insider trading policy and federal securities laws, those stockholders may sell their shares in the public market. As disclosed in the section titled “Principal Securityholders,” these stockholders collectively own a substantial percentage of our outstanding shares. Sales of a significant number of shares by any of these stockholders in the public market, or even the perception that such sales may occur, could result in a decline in the market price of our common stock. These potential sales could also increase volatility in our stock price, particularly given the relatively low public float of our common stock. Moreover, such sales may impair our ability to raise capital through future equity offerings on favorable terms, or at all, by exerting downward pressure on our stock price or by signaling to potential investors a lack of long-term commitment by key stockholders. If we are unable to raise necessary capital when needed, our business, financial condition, and results of operations may be materially and adversely affected.

We have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

Our management will have broad discretion in the application of the net proceeds from this offering, including for any of the purposes described in the section titled “Use of Proceeds,” and you will not have the opportunity as part of your investment decision to assess whether the net proceeds are being used appropriately. Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. Our management might not apply our net proceeds in ways that ultimately increase the value of your investment. We expect to use the net proceeds of this offering, together with our existing cash and cash equivalents, for working capital and other general corporate purposes, including sales and marketing activities and product development. The failure of our management to apply these funds effectively could harm our business. Pending their use, we may invest the net proceeds from this offering in short- and intermediate term, investment-grade, interest-bearing securities. These investments may not yield a favorable return to our stockholders. If we do not invest or apply the net proceeds from this offering in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline.

Our business and operations could be negatively affected if we become subject to stockholder activism or hostile bids, which could cause us to incur significant expense, hinder execution of our business strategy and impact our stock price.

Stockholder activism—ranging from proxy contests and hostile bids to public campaigns and litigation—has become increasingly prevalent. Declines in our stock price may heighten our vulnerability to unsolicited approaches, potentially disrupting our business strategy and operations.

In January 2025, Orbic North America, LLC (“Orbic”), an affiliate of a competitor currently engaged in intellectual property litigation against us, announced an “agreement in principle” with AJP, our largest stockholder, to acquire a portion of AJP’s shares. AJP is controlled by our director Jeffrey Wang, who beneficially owns approximately 19% of our outstanding common stock. Following this announcement, our board formed a Special Committee to evaluate strategic alternatives. Thereafter, AJP, Orbic, and their affiliates formed a group pursuant to Section 13 of the Exchange Act (the “Orbic Group”), and Orbic entered into an irrevocable proxy agreement granting it control over all of AJP’s voting power. The Orbic Group submitted a purported acquisition proposal and a purported notice to nominate an alternative slate of director candidates for election at our 2025 annual meeting (the “Notice”). Our board rejected the Notice as deficient, and AJP and Orbic subsequently initiated litigation against the Company and all of our directors except Mr. Wang, as described in the subsection titled “Legal Proceedings” below. Our board subsequently elected to waive the deficiency of the notice and permit the Orbic Group to nominate its director candidates for election at our 2025 annual meeting.

Responding to such actions by activist stockholders can be costly and time-consuming, disrupt our operations, and divert the attention of management and our board of directors. If AJP and Orbic are successful in the litigation and proxy contest, they could gain control of our board of directors, potentially pursuing actions advanced by our competitor that conflict with our long-term strategic objectives. Actions of AJP and Orbic may also discourage or deter a potential acquirer of Sonim from considering Sonim as a desirable acquisition target.

The presence of an activist stockholder or the perception of a potential hostile takeover may create uncertainty regarding our future direction, strain relationships with business partners, and impact our ability to attract and retain key personnel. In fact, Sonim has already had to dispel market rumors regarding potential hostile actions by Orbic, which has required management’s time and effort.

Our evaluation of strategic alternatives may not lead to a favorable outcome and could create business disruption and stock price volatility.

In January 2025, we formed a Special Committee composed solely of independent directors to evaluate potential strategic alternatives aimed at enhancing stockholder value. These alternatives could include acquisitions, divestitures, mergers, partnerships, financings, or a sale of the company. The Special Committee was formed in response to the Schedule 13D/A filing by AJP on January 17, 2025, and it subsequently received an unsolicited, non-binding proposal from Orbic. On June 2, 2025, we announced a letter of intent in connection with a potential sale of assets transaction with Social Mobile, and explained our vision of the Sonim strategic alternatives.

The process of reviewing potential strategic alternatives may be time-consuming, distracting, and disruptive to our business operations, which may cause concern to our employees, investors, strategic partners, and other constituencies and may have a material impact on our business and operating results and/or result in increased volatility in our share price. We have and will continue to incur substantial expenses associated with identifying, evaluating, and negotiating potential strategic alternatives.

There can be no assurance that our strategic review process will result in any transaction or other strategic outcome. We do not intend to disclose further developments on this strategic review process unless and until we determine that such disclosure is appropriate or necessary. If we determine to engage in a transaction as a result of our exploration and evaluation of strategic alternatives, our future business, prospects, financial position and operating results could be significantly different than those in historical periods or projected by our management. Moreover, the review of strategic alternatives may disrupt our business by causing uncertainty among current and potential employees, suppliers, customers and investors. The selection and execution of a strategic alternative may lead to similar disruptions, and parties advocating for alternatives not selected may solicit support for such other alternatives, causing further disruption. Until the process is concluded, perceived uncertainties related to our future may result in the loss of potential business opportunities and volatility in the market price of our common stock and may make it more difficult for us to attract and retain qualified personnel and business partners.

The occurrence of any one or more of the above risks could have a material adverse impact on our business, financial condition, results of operations and cash flows.

We are required to meet the Nasdaq continued listing requirements and other Nasdaq rules, or we may risk delisting. Delisting could negatively affect the price of our common stock, which could make it more difficult for us to sell securities in a future financing or for you to sell our common stock.

We are required to meet the continued listing requirements of the Nasdaq and other Nasdaq rules, including those regarding director independence and independent committee requirements, minimum stockholders’ equity, minimum share price and certain other corporate governance requirements. In particular, we are required to maintain a minimum bid price for our listed common stock of $1.00 per share (which we previously failed to meet resulting in two reverse stock splits in a five-year period in order to regain compliance) and either a minimum stockholders’ equity of $2,500,000, or a minimum market value of our common stock of at least $35,000,000. If we do not meet these continued listing requirements, our common stock could be delisted. We have a history of receiving deficiency letters from Nasdaq.

If Nasdaq delists our common stock from trading on its exchange and we are not able to list our common stock on another national securities exchange, we expect our common stock could be quoted on an over-the-counter market. If this were to occur, we could face significant material adverse consequences, including:

Sales of our common stock under resale registration statements or the perception of such sales in the public market or otherwise could cause the market price for our common stock to decline, even if our business is doing well.

Resales of our common stock may cause the market price of our securities to drop significantly. The sale of shares of our common stock in the public market or otherwise, or the perception that such sales could occur, could reduce the prevailing market price of shares of our common stock and increase the volatility of our share price.

Such sales could occur pursuant to two effective Form S-3 Registration Statements and prospectuses, dated, respectively, December 1, 2023, (the “AJP Registration Statement”) and September 16, 2024 (the “Liu Registration Statement”), as well as pursuant to a Form S-3 Registration Statement we are obligated to file with the SEC on or before July 12, 2025 (the “2025 PIPE Registration Statement”).

These sales, or the possibility that these sales may occur, also might make it more difficult for us:

Resales of our common stock may cause the market price of our securities to drop significantly.

As of the filing date of this prospectus:

Until such time that these registration statements are no longer effective, they will permit the resale of the registered shares. As such, sales of a substantial number of shares of our common stock in the public market could occur at any time.

Our quarterly results may vary significantly from period to period, which could make our future results difficult to predict and could cause our operating results to fall below investor, analyst, or our expectations.

Our quarterly results and, in particular, our revenue, gross margins, operating expenses, operating margins and net income (loss), have historically varied significantly from period to period and may continue to do so in the future. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Our budgeted expense levels are based, in large part, on our expectations of future revenue and the development efforts associated with that future revenue. Due to our smaller scale compared to many of our customers, we are particularly vulnerable to the impacts of changes in these customers’ order forecasts. Consequently, if our revenue does not meet projected levels in the short term, our inventory levels, cost of revenues and operating expenses would be high relative to revenue, resulting in potential operating losses. If our revenue or operating results do not meet the expectations of investors, the price of our common stock may decline substantially.

Factors that may contribute to fluctuations in our quarterly results, many of which are outside our control and may be difficult to predict, include:

The financial and operational projections that we may provide from time to time are subject to inherent risks.

The projections and timelines that our management may provide from time to time (including with respect to financial or operational matters and the expansion of our product portfolio and business lines) reflect numerous assumptions made by our management with respect to our specific, as well as general business, economic, market and financial conditions, including our ability to correctly assess the demand to such products from different consumers and other matters, all of which may be difficult to predict and many of which are beyond our control.

Accordingly, there is a risk that the assumptions made in preparing the projections, or the projections themselves, will prove inaccurate or that our organic growth and expansion may be curtailed. You should be prepared for differences between actual and projected results from time to time. Our future actual results may be materially different from those contained in our projections, both as to amounts and as to timing. The inclusion of projections or timelines in our Annual Report on Form 10-K or any other filings we make with the SEC or otherwise communicated to investors by us should not be regarded as an indication that we or our management or representatives considered or consider such projections and timelines to be a reliable prediction of future events, and the projections and timelines should not be relied upon as such.

Some provisions of Delaware law and our certificate of incorporation and bylaws and the adoption of the rights plan may delay or prevent a change in control and may discourage bids for our common stock at a premium over its market price.

Our certificate of incorporation and bylaws provide for, among other things:

These anti-takeover defenses could discourage, delay or prevent a transaction involving a change in control of our company or changes in our management, including transactions in which our stockholders might otherwise receive a premium for their common stock over then current market prices. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and to cause us to take other corporate actions than you desire.

Additionally, we are subject to the provisions of Section 203 of the General Corporation Law of the State of Delaware (“DGCL”), which prohibit a publicly-held Delaware corporation from engaging in a business combination with an interested stockholder, generally a person which together with its affiliates owns, or within the last three years has owned, 15% of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. These provisions of DGCL may have the effect of delaying, deferring or preventing a change in control, and may discourage bids for our common stock at a premium over its market price.

Additionally, on April 21, 2025, the Board declared a dividend of one preferred share purchase right for each outstanding share of common stock, par value $0.001 per share, of the Company, and adopted a stockholder rights plan, as set forth in the Rights Agreement, dated as of April 21, 2025, by and between Equiniti Trust Company, LLC, as rights agent (the “Rights Agent”) and the Company (the “Rights Agreement”), which was previously approved by our board. In connection with the Rights Agreement, a dividend was declared of one preferred stock purchase right for each share of the common stock of the Company outstanding at the Record Date (individually, a “Right” and collectively, the “Rights”). In general terms, the Rights Agreement imposes a significant penalty upon any person or group that acquires beneficial ownership of 15.5% (or, in the case of passive institutional investors, an amount of “less than 20%”) or more of the outstanding shares of common stock without the approval of the Board. The Rights will expire on April 21, 2026  

The Rights Agreement could have the effect of discouraging, delaying or preventing a change in management or control over us. While there is no plan to do so at this time, our board may choose to extend the current Rights Agreement or adopt a new rights agreement in the future.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain stockholder litigation matters and the U.S. federal district courts as the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees, agents or trustees to us or our stockholders, (iii) any action asserting a claim against us or any director or officer or other employee of ours arising pursuant to any provision of the DGCL, our amended and restated certificate of incorporation or our bylaws or (iv) any action asserting a claim against us or any director or officer or other employee of ours that is governed by the internal affairs doctrine, in each such case subject to such Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. Our certificate of incorporation also provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. However, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce a duty or liability created by the Securities Act or the rules and regulations thereunder; accordingly, we cannot be certain that a court would enforce such provision. Our certificate of incorporation further provides that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have notice of and consented to the provisions of our certificate of incorporation described above; however, our stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder. The forum selection provisions in our certificate of incorporation may have the effect of discouraging lawsuits against us or our directors and officers and may limit our shareholders’ ability to obtain a favorable judicial forum for disputes with us. If the enforceability of our forum selection provision were to be challenged, we may incur additional costs associated with resolving such a challenge. While we currently have no basis to expect any such challenge would be successful, if a court were to find our forum selection provision to be inapplicable or unenforceable, we may incur additional costs associated with having to litigate in other jurisdictions, which could have an adverse effect on our business, financial condition and results of operations and result in a diversion of the time and resources of our employees, management and the board of directors.

The market price of our common stock is likely to be volatile and could fluctuate or decline, resulting in substantial loss of your investment.

The market price of our common stock could be subject to wide fluctuations in response to, among other things, the factors described in this “Risk Factors” section or otherwise, and other factors beyond our control, such as fluctuations in the valuations of companies perceived by investors to be comparable to us.

Furthermore, the stock markets have experienced price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market fluctuations, as well as general economic, systemic, political, and market conditions, such as recessions, interest rate changes, or international currency fluctuations, may negatively affect the market price of our common stock.

The trading price of our common stock is likely to be volatile and subject to wide price fluctuations in response to various factors, including:

These and other factors may cause the market price and demand for our common stock to fluctuate substantially, which may limit or prevent investors from readily selling their shares of common stock and may otherwise negatively affect the liquidity of our common stock. In addition, in the past, when the market price of a stock has been volatile, holders of that stock have often instituted securities class action litigation against the company that issued the stock.

General Risk Factors

Natural or man-made disasters and other similar events may significantly disrupt our business, and negatively impact our operating results and financial condition.

Any of our facilities may be harmed or rendered inoperable by natural or man-made disasters, including earthquakes, tornadoes, hurricanes, wildfires, floods, nuclear disasters, acts of terrorism or other criminal activities, infectious disease outbreaks, and power outages, which may render it difficult or impossible for us to operate our business for some period of time. Any disruptions in our operations could negatively impact our business and operating results and harm our reputation. In addition, we may not carry business insurance or may not carry sufficient business insurance to compensate for losses that may occur. Any such losses or damages could have a significant adverse impact on our business, operating results and financial condition. In addition, the facilities of significant vendors may be harmed or rendered inoperable by such natural or man-made disasters, which may cause disruptions, difficulties or significant adverse impact on our business.

Our operations and performance depend significantly on global and regional economic conditions and adverse economic conditions can materially adversely affect our business, results of operations, and financial condition.

We are highly susceptible to the global supply chain and any disruptions. The majority of our suppliers and manufacturing facilities are located outside the U.S. As a result, the Company’s operations and performance depend significantly on global and regional economic conditions.

Adverse macroeconomic conditions, including inflation or recession, new or increased tariffs and other barriers to trade, changes to the U.S. fiscal and monetary policy, tighter credit, higher interest rates, high unemployment, currency fluctuations, changes in the volume and relative mix of U.S. government spending, international disputes, geopolitical tensions, and conflict can adversely impact consumer confidence and spending and materially adversely affect demand for our products and services. In addition, consumer confidence and spending can be materially adversely affected in response to financial market volatility, negative financial news, declines in income or asset values, energy shortages and cost increases, labor and healthcare costs, and other economic factors. Besides an adverse impact on demand for our products, uncertainty about, or a decline in, global or regional economic conditions can have a significant impact on our counteragents including customers, suppliers, contract manufacturers, logistics providers, cellular network carriers, and channel partners.

These and other economic factors can materially adversely affect the Company’s business, results of operations, financial condition, and stock price.

Economic uncertainties or downturns, or political changes, could limit the availability of funds to our customers and potential customers, which could significantly adversely impact our business.

Current or future economic uncertainties or downturns could adversely impact our business and operating results. Negative conditions in the general economy both in the United States and abroad, including conditions resulting from changes in gross domestic product growth, financial and credit market fluctuations, political deadlock, natural catastrophes, infectious disease outbreaks, geopolitical tensions and warfare and terrorist attacks in North America, Europe, the Asia Pacific region or elsewhere, could cause a decrease in funds available to our customers and potential customers and negatively affect the growth rate of our business.

These economic conditions may make it extremely difficult for our customers and us to forecast and plan future budgetary decisions or business activities accurately, and they could cause our customers to reevaluate their decisions to purchase our solutions, which could delay and lengthen our sales cycles or result in cancellations of planned purchases. Furthermore, during challenging economic times or as a result of political changes, our customers may tighten their budgets and face constraints in gaining timely access to sufficient funding or other credit, which could result in an impairment of their ability to make timely payments to us. In turn, we may be required to increase our allowance for doubtful accounts, which would adversely impact our financial results.

We cannot predict the timing, magnitude or duration of any economic slowdown, instability or recovery, generally or within any particular industry, or the impact of political changes. If the economic conditions of the general economy or industries in which we operate worsen from present levels, or if recent political changes result in less funding being available to purchase our solutions, our business, operating results and financial condition could be adversely impacted.

Foreign currency fluctuations may reduce our competitiveness and sales in foreign markets.

The relative change in currency values creates fluctuations in product pricing for international customers. These changes in foreign end-customer costs may result in lost orders and reduce the competitiveness of our products in certain foreign markets. These changes may also negatively impact the financial condition of some foreign customers and reduce or eliminate their future orders of our products. In addition, a significant portion of our research and development expenditure takes place in China and India. Fluctuations in the currency values of those countries could negatively impact our operating expenses.

Use of Proceeds

We estimate that the net proceeds to us from this offering, after deducting placement agent fees and estimated offering expenses payable by us, will be approximately $9.0 million. Additionally, because this is a “best efforts” offering and there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, the placement agent’s fees and net proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth on the cover page of this prospectus. As a result, we may receive significantly less in net proceeds. Based on the assumed offering price set forth above, we estimate that our net proceeds from the sale of 75%, 50%, and 25% of the securities offered in this offering would be approximately $6.7 million, $4.4 million, and $2.1 million, respectively, after deducting the estimated placement agent fees and estimated offering expenses payable by us.

We intend to use the net proceeds for our operations, including the purchase of life settlement policies, supporting our overall business strategy, working capital purposes and general corporate purposes, which may include repayment and refinancing of our indebtedness. We have not yet determined the manner in which we will allocate the net proceeds from this offering, and as a result, management will have broad discretion in the allocation and use of the net proceeds. We may temporarily invest the net proceeds from this offering in cash and cash equivalents or short-term marketable securities until they are used for their stated purpose.

The Company reserves the right to change the use of proceeds, provided that such reservation is due to certain contingencies that are discussed specifically and the alternatives to such use in that event are indicated.

Dilution

If you invest in our common stock, your interest will be diluted to the extent of the difference between the price per share you pay in this offering and the net tangible book value per share of our common stock immediately after this offering. Dilution with respect to net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the net tangible book value per share of our common stock immediately after this offering.

Our net tangible book value of our common stock as of March 31, 2025 was approximately $(1.1 million), or approximately $(0.17) per share of common stock based upon 6,333,657 shares outstanding as of such date. Net tangible book value per share is equal to our total tangible assets, less our total liabilities, divided by the total number of shares outstanding as of March 31, 2025.

After giving effect to the sale of our common stock in the aggregate amount of $10.0 million at the public offering price of $1.45 per share and after deducting placement agent fees and estimated offering expenses payable by us, our net tangible book value as of March 31, 2025 would have been approximately $8.0 million, or $0.60 per share of common stock. This represents an immediate increase in net tangible book value of $0.77 per share to our existing stockholders and an immediate dilution in net tangible book value of $0.85 per share to new investors in this offering at the assumed public offering price.

The following table illustrates this calculation on a per share basis:

The number of shares of our common stock to be outstanding immediately after this offering for the purpose of the above discussion and table is based on 6,333,657 shares of our common stock outstanding as of March 31, 2025, and excludes, as of such date:

To the extent that options or warrants have been or are exercised, or other shares are issued, investors purchasing shares in this offering could experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

Capitalization

The following table sets forth our cash and cash equivalents and capitalization as of March 31, 2025:

Our capitalization following the closing of this offering will be adjusted based on the actual public offering price and other terms of this offering determined at pricing.

Business

Overview

Sonim Technologies, based in the United States, is a leading provider of enterprise 5G solutions, offering a robust portfolio that includes rugged handsets, smartphones, wireless internet devices, software, services, and accessories. Our products are engineered to deliver reliable communication in challenging and unpredictable environments, serving sectors such as critical communications, first responders, government, industrial, construction, hospitality, and logistics. We distribute our products primarily through major wireless carriers. We currently have products available at all three U.S. Tier-one carriers – AT&T, T-Mobile and Verizon as well as the three primary carriers in Canada – Bell, Telus and Rogers, Telstra in Australia, and multiple carriers throughout Europe. These carriers resell our products, along with network services, to end customers focusing on two primary-end markets: industrial enterprise and the public sector. We also sell our products through distributors and resellers in various markets, including Europe and South Africa.

Sonim is executing a strategic expansion initiative, focusing on broadening its market reach with new products, geographical footprint, and customer segments including enterprise, small and medium business, and prosumers. This strategy is underpinned by a strong emphasis on execution. We have introduced new product categories: Connected Solutions featuring wireless internet products, a next-generation rugged smartphone, and a new range of mid and low-tier professional rugged phones, all boasting IP ratings, MIL-STD-810H standards, and elements of Sonim’s Rugged Performance Standards (“RPS”), highlighting our value proposition to target markets.

During the second half of 2024 and through the filing date of this prospectus, Sonim launched the following products:

Additionally, the XP10 is now available through our distribution partners in EMEA and Australia. Most of these products are supported by the SonimWare platform and enterprise services. In the first quarter of 2025, the XP Pro 5G and H500 5G each received Verizon Frontline certification. In the first quarter of 2025 we also announced the upcoming launch and availability of the XP Pro Thermal 5G smartphone for Europe which includes an SDK-enabled Sonim IRIS software for custom application development and an integrated thermal camera by FLIR® that benefits a number of vertical trades such as electricians, plumbers, public safety, construction, agriculture, amongst others.

Geographic market expansion continues with agreements and product availability through new distribution partners in Europe and South Africa, catering to carrier, reseller, and enterprise sales channels. New partners include TCCM, Brodos, Modino, Ingram Micro, and Cernotech, which bolster our presence in these regions. This strategic alignment supports our commitment to offering reliable solutions and expanding our customer base.

During the first half of 2024, Sonim undertook a strategic shift away from low-margin white label products, a transition that was expedited due to manufacturing challenges faced by our partners. This shift resulted in a decline in revenue for the year, with 2024 revenue totaling $58.3 million, compared to $93.6 million in 2023. Our net loss for 2024 was $33.6 million, compared to $0.1 million in 2023. However, with the introduction of new product lines in the fourth quarter of 2024 and in the first half of 2025, we anticipate a return to revenue growth and improved profitability in 2025.

With the primary sales channels in the U.S. and Canada consisting of large wireless carriers, the Company’s customer base is highly concentrated, as represented in the tables below (all figures as a percentage of our total net revenues):

Revenue by Customer Type

 Revenue by Product Type

In alignment with Sonim Technologies’ commitment to quality, reliability, and regulatory compliance, we have prioritized our Trade Agreements Act (“TAA”) initiatives. TAA compliance is crucial in enhancing our market strategy, particularly in expanding opportunities within government and enterprise markets, which demand stringent adherence to regulatory standards. By ensuring our products meet TAA requirements, we reinforce our position as a trusted provider of enterprise 5G solutions.

This initiative underscores our dedication to delivering products that not only meet industry-leading standards but also comply with U.S. federal procurement regulations, thereby enhancing our competitiveness in securing government contracts.

Looking ahead, Sonim is focused on bringing our new products and solutions offering to our expanded portfolio throughout 2025.

Our Products

Ruggedized Cell Phones

Communication, data collection, productivity and safety among task workers have always been central requirements in business-critical and mission-critical environments. Organizations with remote and disparate workers—from police and firefighters to construction, oil rig, logistics and manufacturing workers—need an extremely durable solution that provides reliable and secure voice, data and workflow applications. The global market for rugged devices continues to grow, and we believe that the use of consumer phones in line-of-business applications provides an attractive market opportunity. Ruggedized mobile phones are well suited for industrial enterprise and other critical infrastructure applications due to their durability and functionality in a range of environments. Equipping workers with smarter mobile phones also helps enable more efficient communication with and between field employees and enhances the information that decision-makers use to deploy resources within their organizations. The timing of our growth into Europe and other areas outside of North America has accelerated due to the shutdown of a former competitor, Bullitt Group Ltd. (“Bullitt”), in January 2024. We have expanded our sales force and increased our service infrastructure to serve customers that were previously served by Bullitt.

Connected Solutions Market

Our Connected Solutions product portfolio includes mobile hotspots and fixed wireless access (“FWA”) devices that connect to the internet through the 4G and 5G cellular networks. Mobile operators receive data subscription revenue by providing these devices to their customers to access the internet. These devices replace cable internet access and provide new access to rural areas. The market for these solutions continues to grow in North America and in Europe. We created a division to design, develop and sell connected solutions devices. With competition exiting the carrier space as well as non-competitively priced products in the market, Sonim believes that this space is a great opportunity for expansion. Sonim has developed feature-rich devices that are competitively priced.

Key Features of Our Ruggedized Solutions

As a result of these key attributes, we believe that our ruggedized, purpose-built mobile solutions can increase the productivity of task workers and significantly reduce the total cost of ownership for entities deploying our solutions.

Our Strategy

The three pillars of our go-forward strategy are as follows:

Our strategy includes the following:

Our Target Markets

We believe that our solutions can improve communication reliability, operational efficiency and safety for end customers and task workers in commercial sectors, public sectors, and for individual retail customers. Our ruggedized mobility solutions target three end markets: industrial enterprise, public sector, and consumers that demand a more durable product.

Industrial Enterprise

Transportation and Logistics. Enterprises and fleet workers across supply chain, delivery services, airport workers, and field management rely on mobile devices to operate safely and efficiently in environments that are often susceptible to inclement weather. For enterprises looking to improve supply chain functionality, our mobile resource management applications such as location tracking, mileage tracking, and job dispatch can help businesses monitor operations more efficiently. We believe that a weather-resistant and long-battery ruggedized device, combined with productivity applications and services with the native camera on our smartphones, provides reliable communication options for transportation and logistics workers. In addition, our solutions reduce the number of devices and tools that these task workers would need to carry in the field by consolidating the functionality of multiple single-purpose devices into one purpose-built mobile device.

Construction. We offer workers in the construction industry crush-, puncture-, scratch- and impact-resistant devices, which we believe to be crucial in environments where there is a high risk of such occurrences. Job sites also value the PTT capabilities that are tightly integrated into Sonim devices. Additionally, we believe our phones and related accessories help promote worker safety and productivity, with support for lone-worker safety applications and with features such as extended battery life and extra-loud speakers. For business decision-makers, we offer devices with consolidated functionality, which enables a total cost of ownership that we believe is significantly lower versus comparable offerings that enable real-time reporting. This can help eliminate costly delays by capturing verbal, visual, and location data from job sites more efficiently.

Manufacturing. As market demand and competition in the manufacturing sector require more nimble production lines, equipment for reliable communication and safety standard compliance are necessary to improve efficiency and keep workers safe. Our devices’ PTT functionality and extra-loud speakerphones are designed to keep lines of communication open and functional in fast-changing and loud environments, while our glove-friendly touchscreen displays allow workers to have access to real-time data, thus reducing production downtime. Additionally, our devices are designed to survive blunt force and can be sanitized and sterilized for safe use in food or medical processing facilities. We believe that these features can enhance the productivity of workers in the manufacturing industry.

Facilities Management. Service-based operations in large indoor and outdoor facilities, including recreation parks, require management of mobile teams. Our mobile phones consolidate radio, guard tour verification, panic button systems and scanners, which otherwise would require separate and single-purpose equipment. Our devices can improve business operations through functionalities such as automated work order dispatch and job completion verification tools delivered via proprietary third-party applications integrated with our devices.

Energy, Mining, and Utilities. The safety standards for mobile phones used in the energy and utility industry are more stringent due to the reactive characteristics of the natural resources being procured and serviced, as well as the potentially high-voltage or explosive environments. We believe we are uniquely positioned to serve these workers because a number of our devices are designed for use in potentially explosive or hazardous environments (rated Non-Incendive or Intrinsically Safe by either the CSA Group, ATEX or IECEx notified bodies), and their resistance to various chemicals and extreme temperatures. Reliable communication devices are often mission-critical for workers to stay safe while performing energy- and utility-related operations.

Public Sector

Public Safety. In the United States, AT&T’s FirstNet, T-Mobile’s T-Priority, and Verizon’s Frontline public safety prioritization provide optimized networks for this sector. Through our partnerships with the major wireless carriers, we believe we are in a strong position to provide mission-critical solutions to the public safety market as public safety networks mature. Through enhanced communication capabilities, our devices can decrease the response time of first responders and help public safety workers stay safe and connected in hazardous, isolated or emergency conditions. The durability of our phones, combined with their purpose-built functionality, provides a lower total cost of ownership compared to similar products, which is highly attractive to city and state decision-makers.

Federal Government. Whether during natural disasters or day-to-day operations, our devices help provide functionality and reliability that is crucial for federal workers to protect and serve their nation. Our mobile solutions support purpose-built voice communications and data capture applications that allow federal workers to stay connected and quickly make more informed decisions while in the field.

Small Business Users

As small businesses grow more reliant upon mobile devices to support all of their daily activities, mobile devices are now more than ever being placed into situations and environments that are more prone to physical damage including screen breakage and water damage. We believe that this market is currently underserved with only higher cost devices offering the features that are needed. Sonim’s value proposition will be to offer an overall lower total cost of ownership as a small business will not need to lose valuable downtime and money repairing or replacing their device as often as other devices in the market. In the fourth quarter of 2024, we launched a new semi-rugged smartphone that is sleeker and lighter than our ultra-rugged phones. These phones will be targeted at small business users.

Home and Small Business Internet Users

Mobile hotspots are used by businesses, government employees and consumers. Having the ability to access the internet (and at times share the connection) in a secure way wherever the customers go is essential to many users. Whether it is a salesperson visiting their customers, a police officer using their computer in their patrol car, a small business in need of failover for business continuity in the event of an internet outage, a student working on a paper or a family going on vacation, the need for reliable internet has become a necessity in today’s world. Mobile hotspots provide the perfect vehicle for enabling these use cases. We will be launching additional mobile hotspots in 2025.

Fixed wireless access provides an economical way for operators to quickly deploy internet to new customers without having to lay costly new cable or fiber. This service is used by businesses and consumers alike. Historically internet connectivity was effectively a monopoly business with major fixed wireline operators dividing up the country. Consumers had little choice when it came to options for internet service. With 5G, wireless operators are using fixed wireless access as a way to add new revenue streams to their businesses. Additionally, fixed wireline operators are using fixed wireless access as a way to quickly deploy to rural areas that were not served by cable companies.

Products and Technology

Features of Our Ruggedized Mobile Phones

Our mobile phones can withstand a variety of harsh environments and are supported by our industry-leading three-year comprehensive manufacturer’s warranty for our ultra-rugged devices. We developed our devices to meet industry standards for protection from the ingress of water and/or micro-particles (IEC standard 60529). Our devices are rated a minimum of IP-68, allowing them to be submersed in up to six and a half feet of water for up to 30 minutes, and our XP10 smartphone has been further tested and certified to withstand sprays of high-pressure streams (up to 1,450 PSI) of hot (80°C) water (IPx9K). We have additionally designed and manufactured our devices to withstand repeated drops to concrete across all angles and faces, attaining MIL-STD-810G ratings and, in 2011, earning the Sonim XP3300 the title of World’s Toughest Phone by the Guinness Book of World Records after surviving a fall from 82 feet 11.7 inches to concrete. Engineered with a protective glass lens that is up to three times thicker than that of other cellular devices in the market and a unique blend of plastic and rubber used in the housings, our ultra-rugged mobile phones are designed to be resistant to punctures caused by impacts from external objects up to 2J on the display lens and 4J on the housing. Furthermore, we understand that the jobs of our end users often take them into extreme environments. As a result, we have designed our devices to operate from -4°F to +131°F, be usable while wearing work gloves (glove-friendly touch display, large physical buttons), be audible in noisy environments with loud 100+ dB loudspeakers and multiple microphone noise-cancellation technology, and, for our XP5plus and XP10 phones to last throughout an average day based on ordinary use without needing to be recharged with large, extended-life batteries. We have also designed, manufactured and certified our devices to be safe for use in potentially hazardous or explosive environments.

In addition, our devices provide a wide range of connectivity options for our end customers (including LTE, 3G, 4G, 5G, GSM, WiFi, NFC, location tracking and Bluetooth for certain of our devices), and our phones support a wide range of global frequencies allowing them to be used almost anywhere in the world where there is cellular coverage. Our phones are certified to work on multiple mobile network operators and come equipped with LTE Band 14 to support FirstNet (built with AT&T). We support the latest technologies, including 5G, and we have incorporated 5G into our product roadmap.

Our Devices

Mobile Phone Products

Connected Solutions Products

Accessories

Our portfolio of industrial-grade accessories extends beyond the traditional consumer cellular ecosystem of wall chargers and cases. We work with a number of accessory manufacturers and design partners to deliver innovative purpose-built accessories that enhance the functionality and usability of our devices.

SonimWare Software

In addition to the ecosystem of Android developers and their applications, which are supported on our devices, we provide a suite of applications and tools that help customers manage, deploy and support their Sonim devices. The capabilities of these software applications differentiate us from many rugged vendors that only focus on hardware. Current capabilities include:

Sales and Marketing

As of December 31, 2024, our sales and marketing team consisted of 19 professionals located in the United States, Canada and Europe. We sell our products directly to wireless carriers, through distributors and resellers and directly to end customers. Our marketing efforts consist of product marketing, channel partner/carrier marketing and corporate marketing. Product marketing focuses on ensuring that carrier requirements related to product specifications are in-line with our brand requirements. Channel partner marketing focuses on go-to-market strategy as well as developing supplemental sales tools, carrier and non-carrier marketing campaigns, and industry trade show material. Corporate marketing consists of public relations, brand awareness, social and digital marketing, and lead generation operations.

Customers

While we are actively committed to expanding our customer base on various levels, our sales model mainly focuses on sales through our carrier customers in North America and our distribution partners in Europe, the Middle East, South Africa, and Australia. As a result, a small number of customers account for a large percentage of our net revenue For the three months ended March 31, 2025, wireless carriers contributed 84% of our total net revenues, 32% of which related to the expiration of customer allowance agreements as three of our legacy phones approach end-of-life, with our top three carrier customers accounting for 74% of our total net revenues, 32% of which related to the expiration of customer allowance agreements. For further discussion of our revenue trends and risks related to our customers and contractual relationships, please refer to the “Risk Factors” of this prospectus and sections titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our periodic reports incorporated by reference in this prospectus.

Manufacturing

We have outsourced the manufacturing and the final assembly to third-party ODM partners for our phones and data devices. We have moved the manufacturing of the majority of our newest products outside of China and expect to phase out all manufacturing in China during 2025.

Competition

We operate in a highly competitive environment serving end customers in the industrial enterprise and public sector markets. These markets are highly fragmented, evolving and increasingly competitive. Competition in our industry is intense and has been characterized by rapidly changing technologies, evolving industry standards, significant barriers to entry in the form of carrier certification requirements, frequent new product introductions, annual operating system changes and rapid changes in end user requirements.

Non-rugged mobile device manufacturers have not historically created devices specifically to compete in the industrial enterprise and public sector markets. These manufacturers typically focus on a different consumer audience and the requirements to manufacture ruggedized phones differ significantly from their core products. Nevertheless, we face competition from manufacturers of non-rugged mobile phones such as Apple Inc. and Samsung Electronics Co. Ltd, or Samsung, to the extent that end users decide to purchase traditional devices and add a rugged case for use in environments that we believe are better suited for purpose built ruggedized mobile phones. We also face competition from manufacturers of rugged mobile phones such as Samsung and Kyocera Corporation as well as from large system integrators and manufacturers of private and public wireless network equipment and devices. A large competitor in the rugged phone space, Bullitt Group Ltd., ceased operations in January 2024, which has created an opportunity for us, particularly in Europe.

We believe the principal competitive factors affecting the market for our products are the products’ performance, features (including security features), quality, design innovation, reliability, price, customer service, reputation in the industry, brand loyalty and a strong third-party software and accessories ecosystem. We believe that our strongest competitive advantages are our products’ durability and reputation in the industry, as well as the push to talk capabilities not available in all competitive devices. Additionally, we believe our XP10 rugged smartphone is one of the most rugged smartphones made anywhere in the world and it is consequently able to be fully sterilized and cleaned. In order to compete, we will be required to continue to respond promptly and effectively to the challenges of technological changes and our competitors’ innovations.

Intellectual Property

We hold numerous utility and design patents both inside and outside the United States and have filed additional utility and design patent applications in the United States. We have registered, and applied for the registration of, U.S. and international trademarks, service marks, domain names, and copyrights. We also have contractual rights to standard essential patents for 2G, 3G, 4G, and 5G wireless technologies, some of which require significant royalty payments. We opportunistically negotiate licenses with other patent holders where appropriate for our technology.

Our products are built to conform to wireless standards which are covered by numerous essential patents held by third parties. Our wireless carriers require us to provide patent indemnification for the products we sell to them, and in turn, we secure intellectual property indemnification from our suppliers.

We do not believe that our products infringe on the proprietary rights of any third parties. There can be no assurance, however, that third parties will not claim such infringement by us or our channel partners and end customers with respect to current or future products.

Our smartphone devices use the standard Android operating system and our feature phones use an operating system based on the Android Open Source Project. We additionally integrate third-party licensed software on commercially reasonable terms. Several Android-based apps and extension enablers of Android are developed internally by our employees.

For further discussion of the risks in connection with each of the foregoing matters, see “Risk Factors—Risks Related to Information Technology and Intellectual Property” of this prospectus.

Properties

We maintain our corporate headquarters in a leased facility in San Diego, California. In addition, we lease facilities in Shenzhen, China, in Beijing, China and in Bangalore, India for employees that perform engineering, logistics services, software development. We believe that our facilities are suitable to meet our current needs.

Legislation and Regulation

Wireless communication devices use radio spectrum, which is regulated by government agencies throughout the world. In the United States, use of spectrum is regulated by the Federal Communications Commission, or FCC, and the National Telecommunications and Information Administration, or NTIA, for non-federal government entities and federal government entities, respectively. The FCC and NTIA allocate spectrum for various uses, including commercial wireless services and public safety services, and regulate the use of that spectrum and the devices, such as our products, that operate on that spectrum. The FCC and NTIA also adopt requirements that affect wireless equipment, such as limits on radio emissions and rules requiring that handsets have specified capabilities, such as providing location information to 911 operators. The FCC also regulates the testing and certification for the import and/or sale of certain wireless devices.

Other countries also have regulatory bodies that define and implement the rules for using radio spectrum, pursuant to their respective national laws and international coordination under the International Telecommunications Union. Our ability to manufacture and sell products in other countries could be affected by such rules. In addition, any significant variations between the rules in the United States and rules in other countries, including differences in available spectrum bands for wireless communication, could increase the costs of designing and manufacturing our products.

Research and Development

We allocate significant resources and funds to developing robust and innovative solutions for the end users of our products and ensuring that these solutions meet their exacting requirements for functionality and reliability. Our research and development initiatives are led by our internal teams and are supported by third-party original design manufacturers as needed. Our product management team and our sales and marketing team spend time interacting with a combination of end users and IT administrators in our target markets, wireless carriers and application and accessory ecosystem partners to better understand the market requirements for our solutions. Once defined, our engineering organization develops and tests the solution against these requirements and works to achieve technical certification and approval from the wireless carriers which allows the solutions to be sold to our end users.

Employees

We had 117 full-time employees and 33 contractors as of March 31, 2025.

None of our employees are represented by a labor union or covered by a collective bargaining agreement. We have not experienced any work stoppages, and we consider our relations with our employees to be good.

Legal Proceedings

General Litigation

The Company is involved in various legal proceedings arising in the normal course of business. The Company does not believe that the ultimate resolution of these other matters will have a material adverse effect on its consolidated financial position, results of operations, or cash flows.

AJP and Orbic Litigation

On April 24, 2025, AJP on behalf of itself and Orbic, filed a complaint (the “Complaint”) in the Delaware Court of Chancery against the Company and directors Mike Mulica, James Cassano, Peter Liu, and Jack Steenstra (the “Director Defendants”). The Complaint alleges that the individual defendants breached their fiduciary duties and seeks, among other relief, a declaration to that effect and an injunction prohibiting enforcement of certain provisions of the Company’s amended and restated bylaws (the “Bylaws”) in connection with the purported notice of nomination (the “Notice”) of proposing a competing slate of directors for election at the Company’s 2025 annual meeting, as more fully described in the Complaint.

The Notice was submitted on the evening of Thursday, March 20, 2025—fewer than two business days before the nomination deadline of Saturday, March 22, 2025—and was determined to be deficient for failing to include all information required under the Bylaws.

AJP beneficially owns approximately 19.04% of the Company’s outstanding common stock. Its sole manager, Jeffrey Wang, is a director of the Company. Orbic, which is a competitor of the Company and an affiliate of Reliance Communications, LLC (“Reliance”), exercises full voting control over AJP’s shares pursuant to an irrevocable proxy agreement. The Company and Reliance are currently involved in litigation in the United States District Court for the Eastern District of New York (Case No. 24-CV-4433), in which each party has asserted claims against the other arising out of allegations by Reliance regarding purported intellectual property violations by the Company, which the Company disputes. On March 18, 2025, Orbic, AJP, and certain affiliates filed a Schedule 13D announcing the formation of a group under Section 13 of the Exchange Act.

Orbic and AJP also filed a motion for expedited proceedings with their complaint. The Delaware Court of Chancery granted the motion for expedited proceedings on May 2, 2025.

On May 11, 2025, our board determined it was advisable and in the best interests of Sonim to waive the deficiency in the Notice rather than engage in protracted litigation. On the same day, Sonim’s counsel notified Orbic’s counsel of the same.

On June 2, 2025, we, AJP, Orbic, and the Director Defendants entered into a Stipulation of Dismissal pursuant to which AJP and Orbic dismissed the Complaint without prejudice.

Mr. Liu

On December 8, 2023, the Company entered an amended and restated employment agreement with Mr. Liu (the “Liu Employment Agreement”), which superseded his previous employment arrangements.

The Crolius Letter Agreement provides for the at-will employment of Mr. Crolius, references the Company’s policies, and contains other customary conditions. The Crolius Base Salary was conditioned to be retroactively effective as of November 1, 2023, and Mr. Crolius was entitled to receive a lump sum payment of the difference between the Crolius Base Salary and the base salary pursuant to his previous employment arrangements. On April 15, 2025, the Company and Mr. Crolius amended the Crolius Letter Agreement, changing the terms of Mr. Crolius’s severance in the event of a change in control, as described below under the title “Potential Payments upon Termination or Change in Control.”

The Becher Letter Agreement provides for the at-will employment of Mr. Becher, references the Company’s policies, and contains other customary conditions.

The Becher Options are subject to the terms and conditions of the EIP.

Potential Payments upon Termination or Change in Control

Each of our NEOs is covered by arrangements that specify certain payments to be made in the event that the executive’s employment is terminated in certain circumstances. These severance benefits are intended to reflect market practices and are designed to attract, retain, and appropriately incentivize and further motivate them to contribute to our short- and long-term success for the benefit of our stockholders, particularly during uncertain times. The severance benefits of all NEOs are subject to customary conditions and applicable tax and other deductions and witholdings.

Liu Employment Agreement

Nonqualified Deferred Compensation

Our named executive officers did not participate in, or earn any benefits under, a nonqualified deferred compensation plan sponsored by us during 2024.

Employee Benefit Plans

We believe that our ability to grant equity-based awards is a valuable and necessary compensation tool that aligns the long-term financial interests of our executive officers with the financial interests of our stockholders. In addition, we believe that our ability to grant options and other equity-based awards helps us to attract, retain and motivate executive officers and encourages them to devote their best efforts to our business and financial success. Vesting of equity awards (other than awards granted in lieu of cash salary or bonus) is generally tied to continuous service with us and serves as an additional retention measure. Our executive officers generally are awarded an initial new hire grant upon commencement of employment.

Each of our named executive officers currently employed by us holds equity awards under our 2019 Equity Incentive Plan that were granted subject to the general terms thereof and the applicable forms of award agreement thereunder. The specific vesting terms of each named executive officer’s equity awards are described under “Outstanding Equity Awards as of December 31, 2024.”

Prior to our initial public offering, we granted all equity awards pursuant to our 2012 Equity Incentive Plan. We currently grant all equity awards pursuant to our 2019 Equity Incentive Plan. All options are granted with a per share exercise price equal to no less than the fair market value of a share of our common stock on the date of the grant. All options have a maximum term of up to 10 years from the date of grant, subject to earlier expiration following the cessation of an executive officer’s continuous service with us.

Options generally remain exercisable for three months following an executive officer’s termination, except in the event of a termination for cause or due to disability or death. Restricted stock unit awards (“RSUs”) generally vest annually over 4 years (other than awards granted in lieu of cash salary or bonus, which may be vested at grant), subject to the continued service with us through each vesting date.

Health and Welfare Benefits

We pay premiums for medical insurance, dental insurance, and vision insurance for all full-time employees, including our named executive officers. These benefits are available to all full-time employees, subject to applicable laws.
