We currently have one reportable operating segment: Wireless.

The wireless industry continues to undergo rapid change on all fronts as connected devices, mobile applications, and digital content are consumed by users who want information, high-speed wireless connectivity and entertainment, anytime, anywhere. While most of us think about being “connected” in terms of computers, tablets and smartphones, the consumer IoT market is creating a world where almost anything can be connected to the wireless Internet. Wearable devices such as smartwatches, fitness trackers, pet trackers and GPS locators, as well as smart home devices, are now commonplace, enabling people, pets, and things to be connected to the “Internet of Everything.” These devices have created an entire ecosystem of over-the-top (“OTT”) apps that provide products over the Internet to bypass traditional distribution methods, while expanding how communication service providers can provide value to mobile consumers.

Although there are numerous business opportunities associated with pervasive connectivity, there are also numerous challenges, including:

•The average age by which most children use smartphones and other connected devices continues to decrease. As such, parents and guardians must be proactive in managing and combating digital lifestyle issues such as excessive screen time, cyberbullying, and online safety;

•As IoT use cases continue to proliferate and scale, management complexity, security and interoperability must be addressed efficiently and correctly;

•Mobile network operators (“MNO”) are being marginalized by messaging applications, and face growing competitive pressure from cable multiple system operators (“MSO”) and others deploying Wi-Fi networks to attract mobile users;

•Enterprises face increasing pressure to mobilize workforces, operations, and customer engagement, but lack the expertise and technologies needed to leverage mobile technology securely and cost-effectively;

•The ubiquity and convenience of e-commerce has created the need for consumer-facing brands to reimagine brick-and-mortar retail experiences; and

•The change in dynamics of work, school and home life has led to an increased use of mobile devices for work, education and entertainment which has given rise to a new set of challenges and issues.

To address these challenges, Smith Micro offers the following solutions:

SafePath®– Comprised of SafePath OS™, SafePath Kids™, SafePath Family™, SafePath Global™, SafePath IoT™, SafePath Home™, and SafePath Premium™, the SafePath product suite provides comprehensive and easy-to-use tools to protect family digital lifestyles and manage connected devices both inside and outside the home. As a carrier-grade, white-label platform, SafePath empowers MNO and cable operators to bring to market full-featured, on-brand family safety solutions that provide in-demand services to mobile subscribers. These solutions include location tracking, parental controls, driver safety functionality, and enhanced AI/machine learning to optimize and customize families' online experience, provide cyberbullying protection, social media intelligence, and public safety notifications for parents or guardians. Our SafePath-based solutions have traditionally been delivered to end-users as value-added services, offering new revenue streams for MNOs while helping to increase brand affinity and reduce subscriber churn. In 2024, we launched two new innovations on our SafePath platform. First, we deployed and launched SafePath Global™, a new deployment and launch model that allows MNOs to rapidly deliver SafePath to their users with faster time-to-market, minimal reliance on MNO's resources, and easy customer onboarding. Second, we launched SafePath Kids, a new and innovative implementation of our solution which enables MNOs to offer rate plans for children with built-in protections, not as a value-added service but as an integral component of the MNO offering. In 2025 we plan to deploy SafePath OS, a software solution designed to be pre-installed and configured on mobile devices to enable MNOs to offer kids phones and senior phones with key features and protections of our SafePath family safety solution out of the box.

ViewSpot® – Our retail display management platform provides wireless carriers and retailers with a way to bring powerful on-screen, interactive demos to life.

With the feature set provided by the ViewSpot platform, wireless carriers and other smartphone retailers can easily customize and optimize the content loops displayed on demo devices so that it resonates with in-store shoppers. Interactive demos created in ViewSpot can be experienced on Android smart devices.

CommSuite® – The CommSuite premium messaging platform helps mobile service providers deliver a next-generation voicemail experience to mobile subscribers, while monetizing a legacy cost-center. CommSuite Visual Voicemail (“VVM”) and Premium Visual Voicemail ("PVVM") quickly and easily allows users to manage voice messages just like email or SMS with reply, forwarding and social sharing options. CommSuite also enables multi-language Voice-to-Text (“VTT”) transcription messaging, which facilitates convenient message consumption for users by reading versus listening. The CommSuite platform is available to both postpaid subscribers as well as prepaid subscribers and is installed on millions of Android handsets in the United States.

Because of our broad product portfolio, deep integration and product development experience and flexible business models we can quickly bring to market innovative solutions that support our customers’ needs, which creates new revenue opportunities and differentiates their products and services from their competitors.

Our marketing and sales strategy is as follows:

Leverage Operator Relationships. We continue to capitalize on our strong relationships with the world’s leading MNOs and MSOs. These customers serve as our primary distribution channel, providing access to hundreds of millions of end-users around the world.

Focus on High-Growth Markets. We continue to focus on providing digital lifestyle solutions, analytics/Big Data solutions, premium messaging services, and visual retail content management solutions.

Expand our Customer Base. In addition to growing our business with current customers, we look to add new MNO and MSO customers worldwide, as well as to expand into new partnerships as we extend the reach of our product platforms within the connected lifestyle ecosystem.

In our business, we market and sell our products primarily to large MNOs and MSOs, so there are a limited number of actual and potential customers for our current products, resulting in significant customer concentration. With the launch of SafePath Global, we plan to expand our customer reach more easily to smaller MNOs and MSOs.

One of the Company's U.S. Tier 1 carrier customers terminated its family safety contract with Smith Micro, effective June 30, 2023, and elected to continue to receive services under the contract for a transitional period through November 30, 2023. The revenues associated with that customer contract were approximately 36% of our total revenues for 2023. We did not have any further revenue from this contract in 2024.

We provide technical support and customer service through our online knowledge base, email, and live chat. Our operator customers generally provide their own primary customer support functions and rely on us for support to their technical support personnel.

The software industry, particularly the wireless market, is characterized by rapid and frequent changes in technology and user needs. We work closely with industry groups and customers, both current and potential, to help us anticipate changes in technology and determine future customer needs. Software functionality depends upon the capabilities of the related hardware. Accordingly, we maintain engineering relationships with various hardware manufacturers, and we develop our software in tandem with their product development. Our engineering relationships with manufacturers, as well as with our major customers, are central to our product development efforts. We remain focused on the development and expansion of our technology, particularly in the wireless space.

The markets in which we operate are highly competitive and subject to rapid changes in technology. These conditions create new opportunities for Smith Micro, as well as for our competitors, and we expect new competitors to continue to enter the market. We not only compete with other software vendors for new customer contracts, in an increasingly competitive and fast-moving market we also compete to acquire technology and qualified personnel.

We believe that the principal competitive factors affecting the mobile software market include domain expertise, product features, usability, quality, price, customer service, speed to market and effective sales and marketing efforts. Although we believe that our products currently compete favorably with respect to these factors, there can be no assurance that we can maintain our competitive position against current and potential competitors. We also believe that the market for our software products has been and will continue to be characterized by significant price competition. A material reduction in the price we obtain for our products would negatively affect our profitability.

Many of our existing and potential customers have the resources to develop products internally that would compete directly with our product offerings. As such, these customers may opt to discontinue the purchase of our products in the future. Our future performance is therefore substantially dependent upon the extent to which existing customers elect to purchase software from us rather than designing and developing their own software.

We protect our intellectual property through a combination of patents, copyrights, trademarks, trade secrets, intellectual property laws, confidentiality procedures and contractual provisions. We have United States and foreign patents and pending patent applications that relate to various aspects of our products and technology. We have also registered, and applied for the registration of, U.S. and international trademarks, service marks, domain names, and copyrights. We will continue to apply for such protections in the future as we deem necessary to protect our intellectual property. We seek to avoid unauthorized use and disclosure of our proprietary intellectual property by requiring employees and third parties with access to our proprietary information to execute confidentiality agreements with us and by restricting access to our source code.

Our customers license our products and/or access our offerings pursuant to written agreements. Our customer agreements contain restrictions on reverse engineering, duplication, disclosure, and transfer of licensed software, and restrictions on access and use of software as a service ("SaaS").

Despite our efforts to protect our proprietary technology and our intellectual property rights, unauthorized parties may attempt to copy or obtain and use our technology to develop products and technology with the same functionality as our products and technology. Policing unauthorized use of our technology and intellectual property rights is difficult, and we may not be able to detect unauthorized use of our intellectual property rights or take effective steps to enforce our intellectual property rights.

As of December 31, 2024, we had a total of 164 employees within the following departments: 117 in engineering and operations, 31 in sales and marketing, and 16 in management and administration. We are not subject to any collective bargaining agreement, and we believe that our relationships with our employees are good. We believe that our strength and competitive advantage is our people. We value the skills, strengths, and perspectives of our diverse team and foster a participatory workplace that enables people to get involved in making decisions. The Company provides various training and development opportunities to foster an environment in which employees are encouraged to be creative thinkers who are driven, focused, and interested and able to advance their knowledge and skills in ever-changing technology.

Our future operating results are highly uncertain. Before deciding to invest in our common stock or to maintain or change your investment, you should carefully consider the risks described below, in addition to the other information contained in this Report and in our other filings with the SEC, including our other Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations. If any of these risks actually occur, our business, financial condition or results of operations could be seriously harmed. In that event, the market price for our common stock could decline and you may lose all or part of your investment.

We sell our wireless products and solutions primarily to large wireless carriers, so there are a limited number of actual and potential customers for our products, resulting in significant customer concentration. For the year ended December 31, 2024, sales to our three largest customers comprised 58%, 20%, and 14% of our revenues. No other customer was greater than 10% of our revenues individually.

Because of our relatively high customer concentration, a small number of significant customers possess a relative level of pricing and negotiating power over us, enabling them to achieve advantageous pricing and other contractual terms, including the ability to terminate their agreements with us with a limited amount of notice. In addition, because our contracts generally provide our customers with the right and license, but not the obligation, to deploy our solutions to their end users, the existence of a contract does not guarantee that our solutions will be deployed as widely as we expect or at all. Any material decrease in our sales to any of these customers, including the termination of contracts with any of these customers or a customer's curtailment or cessation of offering our solutions to their end users, would materially affect our revenue and profitability. The reduction in sales or termination of relationships with any of these customers would also increase the customer concentration and risk as to our remaining large customers.

If there are delays in the distribution of our products or if customer negotiations for our new products cannot occur on a timely basis, we may not be able to generate sufficient revenues to meet the needs of the business in the foreseeable future or at all.

We sell our wireless products for use on handheld devices primarily to our wireless carrier customers, who deploy our products for use by their end user customers. Our wireless carrier customers’ launch of new or updated releases of our products and services may require that we enter into new or amended contracts with them and requires resource and scheduling commitments by our wireless carrier customers and the completion of their internal design, qualification, testing, and other go-to-market processes and approvals, many of which are outside of our control. In the event that we are unable to complete the necessary contract processes, or that our wireless carrier customers withhold or delay the commitment of resources or the completion of necessary internal processes or approvals, we may not be able to launch our new or updated products or services within the timeframes that we expect or at all, and our revenue and financial performance may be adversely affected. In addition, the success of our customers, and their ability and willingness to market to their end users the services that are supported by our products, is critical to our future success. Our ability to generate revenues from our software products and services is also constrained by our carrier customers’ ability to attract and retain customers. We have limited input into or influence upon their marketing efforts and sales and customer retention activities. If our large carrier customers fail to maintain or grow demand for their services, revenues or revenue growth from our products designed for use on mobile devices will decline and our results of operations will suffer.

Our future performance depends in significant part upon the continued service of our senior management and other key technical personnel. We do not have employment agreements with our key employees. The loss of the services of our key employees could materially and adversely affect our business, financial condition, and results of operations. Our future success also depends on our ability to continue to attract, retain, and motivate qualified personnel, particularly highly skilled engineers involved in the ongoing research and development required to develop and enhance our products.

Competition for these employees remains high and employee retention is a common problem in our industry. Our inability to attract and retain the highly trained technical personnel that are essential to our product development, sales, marketing, service, and support teams may limit the rate at which we can generate revenue, develop new products or product enhancements, and generally would have an adverse effect on our business, financial condition, and results of operations.

We and/or the third-party systems that we use to deliver our products and services may be subject to cyber-attacks by third parties seeking unauthorized access to our data or our customers’ or their end users’ data or to disrupt our ability to provide service. Our products and services involve the collection, storage, processing, and transmission of data. The uninterrupted operation of our hosted solutions and the confidentiality and security of our data, our customers’ and their end users’ data, and other third-party information and materials is critical to our business. Any failure to prevent or mitigate security breaches and improper access to or disclosure of our data or our customers’ data or their users’ data, including personal information from users, or of the other third party information and materials in our possession or control, including pre-release mobile devices in our custody, could result in the loss, modification, disclosure, destruction, or other misuse of such data or materials, which could harm our business and reputation, subject us to material liability and diminish our competitive position. In addition, computer malware, viruses, and general hacking have become more prevalent and may occur on our systems or on the third-party systems that we use. Such breaches and attacks may cause interruptions to the services we provide, degrade the user experience, cause our customers and their users to lose confidence and trust in our products and services, impair our internal systems or the third-party systems that we use, and result in financial harm to us.

If we are unable to protect, or our customers and mobile device manufacturer partners perceive that we are unable to protect, the security and privacy of information, data and materials in our care, our growth could be materially adversely affected, and we could be subject to material liability. A security or privacy breach may:

•cause our customers to lose confidence in our solutions;

•cause our mobile device manufacturer partners to cease doing business with us;

•harm our reputation;

•expose us to material liability; and

•increase our expense from potential remediation costs.

While we believe we use proven applications and have established adequate physical and technological safeguards designed for facility security, data security and integrity to process electronic transactions, there can be no assurance that these applications and safeguards will be adequate to prevent a security breach or that in the event of a security breach we will be able to react in a timely manner, or that our remediation efforts will be successful. We also cannot be certain that these applications and safeguards will be or remain sufficient to address changing market conditions or the security and privacy concerns of existing and potential customers and device manufacturer partners. Our efforts to protect our data, our customers’ and their end users' data and the other third party information and materials we receive, and to disable undesirable activities on our systems, may also be unsuccessful due to software bugs or other technical malfunctions, employee, contractor, or vendor error or malfeasance, including defects or vulnerabilities in our vendors’ information technology systems or offerings, breaches of security of our facilities or technical infrastructure, or other threats that may evolve in the future. In addition, our customers and end users may use our products and services in a manner which violates cybersecurity or data privacy laws in one or more jurisdictions. Any significant or high-profile security breach, data privacy breach or violation of data privacy laws could result in the loss of business and reputation, litigation against us, liquidated and other damages, and regulatory investigations and penalties that could adversely affect our operating results and financial condition.

We currently serve our customers from data center hosting facilities. Any damage to, or failure of, such facilities generally could result in interruptions in our service. Interruptions in our service may reduce our revenue, cause us to issue credits or pay penalties, cause customers to terminate their on-demand services, and adversely affect our renewal rates and our ability to attract new customers.

We are dependent on the interoperability of our products with popular operating systems, devices, networks, standards, and other third party technology that we do not control. For example, we depend upon the interoperability of our mobile products with the Android and iOS mobile operating systems. Any changes, bugs or technical issues in such systems, or changes in our relationships with mobile operating system partners, handset manufacturers, mobile carriers, or other third-party technology providers, or in their terms of service or policies that degrade our products’ functionality, reduce, or eliminate our ability to distribute our products, or give preferential treatment to competitive products could adversely affect the usage of our products.

We maintain relationships with mobile device manufacturers which provide us with insights into product development and emerging technologies and which in some cases support our ability to interoperate with mobile devices in the manner necessary for the proper functioning of our products. These insights allow us to keep abreast of, or to anticipate, market trends and help us to serve our current and prospective customers. Mobile device manufacturers are under no obligation to continue providing us with these valuable insights nor to continue to support our interoperability with their devices in the manner necessary for the proper functioning of our products. If we are unable to maintain our existing relationships with mobile device manufacturers, if we fail to enter into relationships with additional mobile device manufacturers, or if mobile device manufacturers favor one of our competitors, our ability to provide products that meet our current and prospective customers’ needs could be compromised and our reputation and future revenue prospects could suffer. For example, if our software does not function well with a popular mobile device because we have not maintained a relationship with its manufacturer, carriers seeking to provide that device to their respective customers may choose an alternative solution. Even if we succeed in establishing and maintaining these relationships, they may not result in additional customers or revenues.

Because mobile software applications are key components of our products and services, the success of our business is dependent on our ability and/or our customers’ ability to distribute our mobile software applications through mobile software application stores, which are subject to terms and policies that are controlled by and subject to change in the discretion of the third-party operators of the application stores, or in certain cases by causing our software applications to be pre-loaded onto the devices that our customers distribute to their end users. In addition, each of the application store operators has approval authority over our mobile software applications as a condition to our distribution of our mobile software applications through the applicable application store, and any delay or withholding of any such approval can lead to delays in the availability of new releases, which may harm our customer relationships and adversely affect our business. There is also no guarantee that any approval will not be rescinded in the future. Any changes to third party application stores or their policies, terms or service or approvals, and where applicable, any delay or interruption in the ability of our software to be pre-loaded onto the devices that our customers distribute to their end users, and other barriers that restrict our ability to distribute our mobile software applications, including government actions, orders, or restrictions, may seriously harm our ability to maintain and/or grow the subscriber base for our products and services and could materially and adversely affect our financial condition and results of operations.

Our software products are complex and may contain undetected defects. If we discover software defects in our products, we may experience delayed or lost revenues during the period it takes to correct these problems. Defects, whether actual or perceived, could result in adverse publicity, loss of revenues, product returns, a delay in market acceptance of our products, loss of competitive position or claims against us by customers. Any such problems could be costly to remedy and could cause interruptions, delays, or cessation of our product sales, which could cause us to lose existing or prospective customers and could negatively affect our results of operations.

As indicated in the report provided from our independent registered public accounting firm, the Company's present financial situation raises substantial doubt about the Company's ability to continue as a going concern without additional capital becoming available to the Company.

While the accompanying financial statements have been prepared assuming that the Company will continue as a going concern, continued operations are dependent upon our ability to execute according to plans, which may include reducing expenditures, obtaining further operational efficiencies, completing equity or debt financings, or securing commercial lines of credit, and ultimately generating profitable operational results. Such financing or lines of credit may not be available on reasonable terms or at all. While the business plans we have established may enable us to meet our financial obligations as they become due over the next twelve months and maintain our current level of operating activities, our ability to continue as a going concern is substantially dependent upon multiple factors, which primarily include those factors set forth above. In order to preserve liquidity, we may also take one or more of the following additional actions:

•Implement additional restructuring and cost reductions,

•Secure a revolving line of credit,

•Dispose of one or more product lines, and/or

•Sell or license intellectual property.

Should we become unable to continue in the normal course of operations, adjustments would be required to the amounts and classifications of assets and liabilities within our consolidated financial statements, and these adjustments could be significant. Our consolidated financial statements do not reflect the adjustments or reclassifications of assets and liabilities that would be necessary if we were to become unable to continue as a going concern.

It is likely that we may need or choose to obtain additional financing to fund our future activities. We could raise these funds by selling more stock to the public or to selected investors, or by entering into borrowing arrangements. We may not be able to obtain additional funds on favorable terms, or at all. If adequate funds are not available, we may be required to curtail our operations or other business activities significantly or to obtain funds through arrangements with strategic partners or others that may require us to relinquish rights to certain technologies or potential markets. Our inability in the future to obtain additional equity or debt capital on acceptable terms, or at all, could adversely impact also our ability to execute our business strategy, which could adversely affect our growth prospects and future stockholder returns.

Additionally, the securities purchase agreements we have entered into in the past, and may enter into in the future, may include certain restrictions restricts or otherwise impair our ability to obtain additional financing using certain types of transactions.

It is possible that our future capital requirements may vary materially from those currently anticipated. The amount of capital that we will need in the future will depend on many factors, including but not limited to:

•the launch and market acceptance of our products;

•the levels of promotion and advertising that will be required to launch our products and achieve and maintain a competitive position in the marketplace;

•our business, product, capital expenditure, and research and development plans and product and technology roadmaps;

•the levels of working capital that we maintain;

•any acquisitions that we would choose to undertake;

•capital improvements to new and existing facilities;

•technological advances;

•our competitors’ response to our products; and

•our relationships with suppliers and customers.

In addition, we may raise additional capital to accommodate planned growth, hiring, and infrastructure needs or to consummate acquisitions of other businesses, products, or technologies.

During 2024 and 2023, we have been in a net loss position, partially driven by the loss of one of our U.S. Tier 1 customers in 2023. In February 2023, following receipt of notice of termination of this U.S. Tier 1 customer contract, we announced we would accelerate our efforts designed to reduce operating costs to advance our ongoing commitment to profitable growth. As a result, we have reduced operating expenditures significantly since that date, and we may need to continue such efforts. We may encounter challenges in the execution of these efforts, and these challenges could impact our financial results. Moreover, although we believe that these efforts have reduced operating costs and improved operating margins, we cannot guarantee that we will sustain the targeted benefits, or that the benefits will be adequate to meet our long-term profitability and operational expectations. Concurrently, we are focusing our efforts on growing our customers’ subscribers on the SafePath platform and offering expanded offerings to our existing and prospective customers that we believe are more closely aligned with their core business objectives, which we expect will increase our revenues, however we cannot guarantee that our efforts will be successful or will result in an increase in our revenues in the manner that we expect or at all. If we do not achieve certain revenue targets subsequent to these efforts, we may need to undertake further cost reduction actions, which may include further restructurings.

The Company's actions to reduce operating costs as a result of the receipt of the notice of termination of one of our U.S. Tier 1 customer contracts caused the Company to incur additional charges related to severance and reorganization activities in 2023 and 2024, which included charges related to employee transition, severance payments, employee benefits, and stock-based compensation. Similar events and/or operating cost reduction efforts in the future could cause the Company to take similar remedial actions, which could cause the Company to incur additional charges in the short-term period following such events or actions. Additional continuing risks associated with the impact of these efforts include employee attrition beyond our intended reduction in force and adverse effects on employee morale, diversion of management attention, adverse effects to our reputation as an employer (which could make it more difficult for us to hire new employees in the future), and potential failure or delays to meet operational and growth targets due to the loss of qualified employees. If we do not realize the expected benefits of our cost reduction efforts on a timely basis or at all, our business, results of operations and financial condition could be adversely affected.

Our operating income or loss can change quarter to quarter and year to year due to a change in our sales mix and the timing of our continued investments in research and development and infrastructure. We continue to invest in research and development, which is vital to maintaining and enhancing our technology portfolio. The timing of these additional expenses can significantly vary quarter to quarter and even from year to year.

As of December 31, 2024, we had total goodwill and net intangible assets of $34.6 million. We assess goodwill and definite lived assets for impairment annually, and we conduct an interim evaluation of definite lived and indefinite lived assets whenever events or changes in circumstances indicate that these assets may be impaired. Our ability to realize the value of goodwill and net intangible assets will depend on the future cash flows of the businesses to which they relate. If we are not able to realize the value of the goodwill and net intangible assets, this could adversely affect our results of operations and financial condition, and also result in an impairment of those assets.

As of March 10, 2025, there were warrants outstanding to purchase up to 8,382,048 shares of our common stock at exercises prices ranging from $1.04 to $21.20. The exercise of some or all of these warrants will dilute the ownership interests of existing stockholders. Any sales in the public market of shares of our common stock that we issued upon exercise of these warrants could adversely affect prevailing market prices of our common stock. In addition, the existence of these warrants may encourage short selling by market participants because the exercise of the warrants could be used to satisfy short positions.

We derive a significant portion of our revenue from wireless carriers. In order to sustain and grow our business, we must continue to sell our software products in this vertical market, and we must seek to expand into additional markets. Shifts in the dynamics of the vertical markets that we serve, such as new product introductions by our competitors, could materially harm our results of operations, financial condition, and prospects. Increasing our sales outside our core vertical markets and into markets in which we do not have significant experience, for example to large enterprises, would require us to devote time and resources to hire and train sales employees familiar with those industries. Even if we are successful in hiring and training sales teams, customers in other vertical markets may not need or sufficiently value our current products or new product introductions.

Our success depends on our ability to anticipate and adapt to changes in technology and industry standards, including changes in the operating systems with which our products are designed to be compatible, and to changes in customer demands. The communications software markets in which we operate are characterized by rapid technological change, changing customer needs, frequent new product introductions, evolving industry standards, and short product life cycles. Any of these factors could render our existing products obsolete and unmarketable. New products and product enhancements can require long development and testing periods as a result of the complexities inherent in today’s mobile technology environment and the performance demanded by customers. If our target markets do not develop as we anticipate, if our products do not gain widespread acceptance in these markets, or if we are unable to develop new versions of our software products that can operate on future wireless networks and PC and mobile device operating systems and interoperate with relevant third-party technology, our business, financial condition and results of operations could be materially and adversely affected.

We operate in markets that are extremely competitive and subject to rapid changes in technology. Because there are low barriers to entry into the software markets in which we participate and may participate in the future, we expect significant competition to continue from both established and emerging software companies, domestic and international. In fact, our growth opportunities in new product markets could be limited to the extent established and emerging software companies enter or have entered those markets. We also may face competition from our existing customers that choose to internally develop and operate a competing product.

Many of our other current and prospective competitors have significantly greater financial, marketing, service, support, technical, and other resources than we do. As a result, they may be able to adapt more quickly than we can to new or emerging technologies and changes in customer requirements, or to devote greater resources to the promotion and sale of their products. Announcements of competing products by competitors could result in our carrier customers reducing, delaying, or withholding the adoption, promotion, or launch of our products and services in anticipation of the introduction of such new products. In addition, some of our competitors are currently making complementary products that are sold separately. Such competitors could decide to enhance their competitive position by bundling their products to attract customers seeking integrated, cost-effective software applications. Some competitors have a retail emphasis and offer OEM products with a reduced set of features. The opportunity for retail upgrade sales may induce these and other competitors to make OEM products available at their own cost or even at a loss. We also expect competition to increase as a result of software industry consolidations, which may lead to the creation of additional large and well-financed competitors. Increased competition is likely to result in price reductions, fewer customer orders, reduced margins, and loss of market share.

In recent years, our revenues derived from sales to customers outside the U.S. have not been material. Our revenues derived from such sales can vary from quarter to quarter and from year to year. In the future, we may expand our international business activities. International operations are subject to many inherent risks, including:

•general political, social and economic instability;

•trade restrictions;

•the imposition of governmental controls;

•exposure to different legal standards, particularly with respect to intellectual property;

•burdens of complying with a variety of foreign laws, including without limitation data privacy laws, such as the General Data Protection Regulation (“GDPR”) in Europe;

•import and export license requirements and restrictions of the United States and any other country in which we operate;

•unexpected changes in regulatory requirements;

•foreign technical standards;

•changes in tariffs;

•difficulties in staffing and managing international operations;

•difficulties in securing and servicing international customers;

•difficulties in collecting receivables from foreign entities;

•fluctuations in currency exchange rates and any imposition of currency exchange controls; and

•potentially adverse tax consequences.

These conditions may increase our cost of doing business. Moreover, as our customers are adversely affected by these conditions, our business with them may be disrupted and our results of operations could be adversely affected.

In the ordinary course of our business, through the delivery of our solutions and in connection with our routine processing of human resources data, we collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, transmit, share and otherwise process confidential, proprietary, and sensitive information, including personal information, and information that may be considered sensitive personal information in certain jurisdictions. As a result, we are subject to numerous data privacy, data protection, and information security obligations, such as various laws, regulations, guidance, industry standards, external and internal privacy and security policies, and contractual requirements, and may become subject to new obligations of this nature in the future.

The data privacy, data protection, and information security laws and regulations to which we are and may become subject address and will address a range of issues, including data privacy, cybersecurity, age-appropriate design, and restrictions or technological requirements regarding the collection, use, storage, protection, retention, or transfer of personal information. The regulatory framework and enforcement mechanisms for data privacy and cybersecurity issues worldwide can vary substantially between jurisdictions. New laws continue to be enacted that may require considerable resources to ensure timely and ongoing compliance given the nuances of each jurisdiction’s legal obligations. For example, more U.S. states are enacting comprehensive data privacy laws similar to the California Consumer Privacy Act of 2018 and the substantial amendments to that framework from the California Privacy Rights Act (CPRA), which took effect in January 2023, that provide new data privacy rights to state residents, expand certain protections to personal information of employees in the state, and create special degrees of protection for certain “sensitive” personal information. The CPRA establishes a dedicated California data protection authority, which may increase enforcement actions and penalties for privacy regulation violations, as well as audits of possible violations. Additionally, expanded business-to-business personal information protections may require additional negotiation of new and existing data processing agreements with service providers. We may also be or become subject to laws requiring age-appropriate design of online products accessed by children, which may require us to expend resources to make conforming updates to our products. Burgeoning legal obligations may require expenditure of considerable resources to establish and maintain the necessary internal infrastructure to comply with monitoring obligations, requests from data subjects, and other requirements, which may limit the use and adoption of our offerings. Other state and federal legislative and regulatory bodies have enacted or may enact similar legislation regarding the handling of personal data.

Foreign privacy and data protection laws and regulations can be more restrictive than those in the United States. For example, in the European Union, the GDPR includes operational and governance requirements for companies that collect or process personal data of residents of the European Union and provides for significant penalties for non-compliance.

The costs of compliance with, and other burdens imposed by, these laws and regulations may become substantial and may limit the use and adoption of our offerings, require us to change our business practices, impede the performance and development of our solutions.

In addition to data privacy and security laws, we are contractually subject to industry standards adopted by industry groups and may become subject to such obligations in the future. We are also bound by other contractual obligations related to privacy, data protection, and information security, and our efforts to comply with such obligations may not be successful. We publish privacy policies, marketing materials, and other statements, such as compliance with certain certifications or self-regulatory principles, regarding privacy, data protection, and information security privacy, data protection, and information security. For the offerings that are distributed by our customers under their respective brands, our customers develop the applicable privacy policies, terms of service and other similar materials and statements. If any of these policies, materials or statements are found to be deficient, lacking in transparency, deceptive, unfair, or misrepresentative of our practices, we may be subject to investigation, claims, litigation, enforcement actions by regulators, contractual penalties or indemnification obligations, or other adverse consequences.

We may at times fail (or be perceived to have failed) in our efforts to comply with our privacy, data protection, and information security obligations. Moreover, despite our efforts, our personnel or third parties on whom we rely, including the third-party providers of services we utilize to deliver some of the functionality of our offerings, may fail to comply with such obligations, which could negatively impact our business operations. If we or the third parties on which we rely fail, or are perceived to have failed, to address or comply with applicable privacy, data protection, and information security obligations, we could face significant consequences, including but not limited to significant fines, penalties, or liabilities for noncompliance, government enforcement actions, litigation (including class-action claims), additional reporting requirements and/or oversight, bans on processing personal information, and orders to destroy or not use personal information. Any of these events could have a material adverse effect on our reputation, business, or financial condition.

Our solutions are distributed by or on behalf of our mobile operator customers, under the mobile operator’s brand, to their end customers. As such our mobile operators, and not the Company, maintain the direct relationship with the end users for our solutions. We require our mobile operator customers to establish appropriate end user terms, privacy policies and other commercial terms with their end users, which include without limitation appropriate license grants and/or rights of use and access, warranty disclaimers, and other customary and contractually agreed terms. If these end user terms, agreements, or policies are deficient, lacking in transparency, deceptive, unfair, lack sufficient warrant disclaimers, misrepresent the role of the Company or are otherwise inadequate to protect the mobile operator’s or the Company’s interests, we may be subject to claims, litigation, or other adverse consequences.

Certain of our customers in the communications industry are subject to regulation by the Federal Communications Commission, which could have an indirect effect on our business. In addition, the U.S. telecommunications industry has been subject to continuing deregulation since 1984. We cannot predict when, or upon what terms and conditions, further regulation or deregulation might occur, or the effect regulation or deregulation may have on demand for our products from customers in the communications industry. Demand for our products may be indirectly affected by regulations imposed upon potential users of those products, which may increase our costs and expenses.

Our success is dependent upon our software code base, our programming methodologies and other intellectual properties and proprietary rights. In order to protect our proprietary technology, we rely on a combination of trade secrets, nondisclosure agreements, patents, and copyright and trademark law. We currently own U.S. trademark registrations for certain of our trademarks and U.S. patents for certain of our technologies. However, these measures afford us only limited protection. For our mobile applications that are distributed by our carrier customers to their end users, we rely on our carrier customers to establish binding end user terms. It is possible that third parties may copy or otherwise obtain our rights without our authorization. It is also possible that third parties may independently develop technologies similar to ours. It may be difficult for us to detect unauthorized use of our intellectual property and proprietary rights. In addition, we sometimes include open-source software in our products.

As a result of our use of open-source software in our products, we may license or be required to license or disclose code and/or innovations that turn out to be material to our business and may also be exposed to increased litigation risk. If the protection of our proprietary rights is inadequate to prevent independent development, unauthorized use, or appropriation by third parties, the value of our brands and other intangible assets may be diminished and competitors may be able to more effectively mimic our products, services, and methods of operations. Any of these events could have an adverse effect on our business and financial results.

We may be subject to claims of intellectual property infringement as the number of trademarks, patents, copyrights, and other intellectual property rights asserted by companies in our industry grows and the coverage of these patents and other rights and the conduct of our business, including the functionality of our products, increasingly overlap. From time to time, we may receive communications from third parties asserting that our trade name or features, content, or trademarks of certain of our products infringe upon intellectual property rights held by such third parties. We have also received and may in the future receive correspondence from third parties separately asserting that our products may infringe on certain patents held by those parties. Although we are not aware that any of our products infringe on the proprietary rights of others, third parties may claim infringement by us with respect to our current or future products.

Additionally, subject to certain limitations, our customer agreements require that we indemnify our customers for infringement claims made by third parties involving our intellectual property, including our software code, embedded in their products, or otherwise distributed by them. Infringement claims, whether with or without merit, could result in time-consuming and costly litigation, divert the attention of our management, cause product shipment delays, result in our sales being enjoined, or require us to enter into royalty or licensing agreements with third parties. If we are required to enter into royalty or licensing agreements, they may not be on terms that are acceptable to us. An injunction or unfavorable royalty or licensing agreements could seriously impair our ability to market our products and have an adverse effect on our business.

Our common stock is currently listed for quotation on the Nasdaq Stock Market. We are required to meet specified requirements in order to maintain our listing on Nasdaq. We could lose our listing on Nasdaq if in the future we become non-compliant with any of the Nasdaq continued listing requirements and, if applicable, we would not remedy such failure within the time allotted by Nasdaq, including for example if the closing bid price of our common stock were to fall and remain below $1.00 per share for more than 30 consecutive business days and we were not able to remedy that failure in the allotted time, or if in the future we would fail to comply with any of the other Nasdaq listing requirements. The loss of our Nasdaq listing would in all likelihood make our common stock significantly less liquid and adversely affect its value.

In the event of a delisting from the Nasdaq Capital Market, our common stock would likely be traded in the over-the-counter inter-dealer quotation system, more commonly known as the OTC. OTC transactions involve risks in addition to those associated with transactions in securities traded on the securities exchanges, such as the Nasdaq Capital Market, or, together, Exchange-listed stocks. Many OTC stocks trade less frequently and in smaller volumes than Exchange-listed stocks. Accordingly, our stock would be less liquid than it would be otherwise. Also, the prices of OTC stocks are often more volatile than Exchange-listed stocks. Additionally, institutional investors are usually prohibited from investing in OTC stocks, and it might be more challenging to raise capital when needed.

A customer’s decision to purchase and launch to the market certain of our products or solutions, particularly products or versions of products that are new to the market, may involve a lengthy contracting, design, and qualification processes, with a timing gap between contracting and launch. Further, a lengthy contracting process, together with lengthy testing, qualification and approval processes are often a prerequisite to our customers’ being in a position to launch updated versions of our products. In particular, customers deciding on the implementation of our products may have lengthy and unpredictable procurement and go-to-market processes that may delay or impact expected revenues. This unpredictability may cause our revenues and operating results to vary unexpectedly from quarter-to-quarter, making our future operational results less predictable.

We have historically made targeted acquisitions of businesses or product lines with technology important to our business strategy and expect to continue to do so in the future. As part of any acquisition, we are required to assimilate the operations, products, and, where applicable, personnel of the acquired businesses and train, retain, and motivate key personnel needed for the successful integration of the acquired business. We may not be able to maintain uniform standards, controls, procedures, and policies if we fail in these efforts. Additionally, as we integrate any newly acquired business into our existing operations, process changes may result in unanticipated or unintended delays in sales of acquired products or services, which could adversely affect our relationships with customers of the acquired business and result in lower revenues from the acquired business than anticipated. Acquisitions may cause disruptions in our operations and divert management’s attention from our Company’s day-to-day operations, which could impair our relationships with our existing employees, customers, and strategic partners. Acquisitions may also subject us to liabilities and risks that are not known or identifiable at the time of the acquisition.

We may also have to incur debt or issue equity securities to finance future acquisitions. Our financial condition could be harmed to the extent we incur substantial debt or use significant amounts of our cash resources in acquisitions. The issuance of equity securities for any acquisition could be substantially dilutive to our existing stockholders. In addition, we expect our profitability could be adversely affected because of acquisition-related accounting costs, impairments, amortization expenses, and charges related to acquired intangible assets. In consummating acquisitions, we are also subject to risks of entering geographic and business markets in which we have had limited or no prior experience. If we are unable to fully integrate acquired businesses, products, or technologies within existing operations, we may not receive the intended benefits of such acquisitions.

Many of the Company’s products and services include third-party intellectual property, which require licenses directly to us or to unrelated companies that provide us with sublicenses and/or execution of services for the operation of our business. The Company has historically been able to obtain such licenses or sublicenses on reasonable terms. There is, however, no assurance that the necessary licenses could be obtained on acceptable terms, or at all, in the future. If the Company or our third-party service providers are unable to obtain or renew critical licenses on reasonable terms, we may be forced to terminate or curtail our products and services which rely on such intellectual property, and our financial condition and operating results may be materially adversely affected.

Our quarterly revenues and operating results have fluctuated significantly in the past and may continue to vary from quarter to quarter due to several factors, many of which are not within our control. If our operating results do not meet the expectations of securities analysts or investors, our stock price may decline. Fluctuations in our operating results may be due to several factors, including the following:

•the gain or loss of a key customer;

•the timing of product and services deployments to our major customers and the timing of our customers’ launch of their branded versions of such products and services to their end users;

•the timing and extent of our customers’ efforts to market and promote such products and services to their users;

•the timing of user acceptance of our customers’ branded versions of our products and services and the growth or decline in the subscriber base for such products and services;

•our ability to maintain or increase gross margins;

•variations in our sales channels or the mix of our product sales;

•our ability to anticipate market needs and to identify, develop, complete, introduce, market and produce new products and technologies in a timely manner to address those needs;

•the availability and pricing of competing products and technologies and the resulting effect on sales and pricing of our products;

•acquisitions;

•the effect of new and emerging technologies;

•deferrals of orders by our customers in anticipation of new products, applications, product enhancements or operating systems; and

•general economic and market conditions.

Our revenues are heavily dependent upon the number of subscribers utilizing our products through our wireless carrier customers. Variations in subscribers, including churn of those subscribers across multiple product and wireless carrier bases can drive volatility in our revenues and result in difficulties in predicting our operating results. Significant sales may also occur earlier than expected, which could cause operating results for later quarters to compare unfavorably with operating results from earlier quarters.

Future orders may come from new customers or from existing customers for new products. The sales cycles may be greater than what we have experienced in the past, increasing the difficulty to predict quarterly revenues.

Because we sell primarily to large wireless carriers, we have no direct relationship with most end users of our products. This indirect relationship delays feedback and blurs signals of change in the quick-to-evolve wireless ecosystem and is one of the reasons we have difficulty predicting demand.

A large portion of our operating expenses, including rent, depreciation, and amortization, is fixed and difficult to reduce or change. Accordingly, if our total revenue does not meet our expectations, we may not be able to adjust our expenses quickly enough to compensate for the shortfall in revenue. In that event, our business, financial condition, and results of operations would be materially and adversely affected.

Due to all of the foregoing factors, and the other risks discussed in this Report, you should not rely on quarter-to-quarter comparisons of our operating results as an indication of future performance.

None.

In our business, we recognize the risk that cybersecurity threats pose to our operations, and as such, cybersecurity is an important component of our overall risk management strategy. We have adopted and implemented an approach to identify and mitigate cybersecurity risks utilizing the National Institute of Standards and Technology’s Cybersecurity Framework (“NIST CSF”) as a guideline to help management identify, assess, reassess, and manage cybersecurity risks. We have developed and implemented cybersecurity programs and processes, including risk management and assessment programs, network segmentation, deployment of detection tools across our network, systems and databases, security and event monitoring capabilities, a detailed incident response plan and an incident response team. Our incident response team is led by our Chief Information Officer, who has over 23 years of experience in information technology leadership and information security, serving in roles of increasing responsibility within private and public companies, and also includes our General Counsel and our Chief Financial Officer. We conduct an initial assessment on the cybersecurity profile of our third party vendors as they are onboarded and evaluate their cyber security programs and safeguards before allowing them access in our environments. We utilize cyber intelligence to provide continuous monitoring and scanning of systems to provide awareness if any of our vendors have security incidents. Within our purchasing and third-party vendor management programs, we require all vendors who handle our data as well as vendors who provide technology and data services to maintain certain security protections including compliance with applicable data protection laws and implementation of administrative, physical, and technical safeguards to protect our data, including storage, transmission, and access. We have implemented advanced detection, prevention and protection capabilities, including practices and tools to monitor and mitigate threats. We provide at least quarterly company-wide cybersecurity information training and routinely communicate with employees about the potential for cybersecurity threats. We additionally deploy technical safeguards that are designed to protect our information systems from cybersecurity threats including firewalls, intrusion penetration and detection systems, anti-malware functionality and access controls, vulnerability assessments and cybersecurity threat intelligence. We continuously monitor and assess our information technology and data assets to detect anomalies and to respond quickly to threats that may arise. In certain instances, we engage third parties to conduct or assist us with conducting cybersecurity risk assessments, information security program assessments and external threat environment reviews.

We perform periodic assessments and testing of our policies, standards, processes, and practices in a manner intended to address cybersecurity threats and events. The results of such assessments are evaluated by management, and we adjust our cybersecurity policies, standards, processes, and practices as necessary based on the information provided by these evaluations.

Our incident response plan sets forth a process for detecting and responding to cybersecurity incidents, determining their scope and risk, developing an appropriate response to mitigate and remediate the incident, assessing materiality and communication or notification requirements, and reducing the likelihood of future incidents. In the event of a real or perceived cybersecurity incident the information technology team would, as soon as practicable, inform the incident response team, the members of which would then collaborate to assess a strategy and manage the risks.

Our risks of security breaches, improper access to or disclosure of our data, our customers’ data or their end users’ data, other hacking attacks on our systems or the third-party systems that we use, or other cyber incidents and privacy breaches could harm our reputation and adversely affect our business, are further disclosed in Item 1A. RISK FACTORS. To date, there have been no cybersecurity incidents which have materially affected, or have been reasonably likely to materially affect, the Company, including our business strategy, results of operations or financial condition. Further, we have a cyber risk insurance policy designed to help us mitigate risk exposure by providing top-tier external cybersecurity firms, as needed, and offsetting certain costs that may be involved with response, recovery and remediation after a cybersecurity breach or similar event.

The audit committee of the Company’s Board of Directors is responsible for overseeing management’s risk assessment and risk management processes designed to monitor and mitigate cybersecurity threats by reviewing with management the cybersecurity and other information technology risks, controls and processes, including the processes used to prevent or mitigate cybersecurity risks and respond to cybersecurity events. The Chief Information Officer, a member of the Company's incident response team, provides reports at least annually to the entire Board of Directors and other members of our senior management team as appropriate. These reports include updates on the Company’s cybersecurity risks and threats, the status of projects to strengthen our information security systems, assessments of the information security program, and the emerging threat landscape. Our Chief Information Officer also regularly updates senior management on our cybersecurity risk governance and management and the status of ongoing efforts to strengthen cybersecurity effectiveness. We also actively engage with key vendors, customers, and industry participants as part of our continuing efforts to evaluate and enhance the effectiveness of our information security policies and procedures.

As dictated by the incident response plan, our audit committee also will receive prompt and timely information regarding cybersecurity threats or incidents that may be material in nature from the incident response team, as well as ongoing updates regarding any such threat or incident until it has been mitigated, resolved, or otherwise addressed.

The Company may become involved in various legal proceedings arising from its business activities. While management does not currently believe that the ultimate disposition of these matters will have a material adverse impact on the Company’s consolidated results of operations, cash flows, or financial position, litigation is inherently unpredictable, and depending on the nature and timing of these proceedings, an unfavorable resolution could materially affect the Company’s future consolidated results of operations, cash flows or financial position in a particular period.

The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the related notes and other financial information appearing elsewhere in this Report. This Report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

Smith Micro provides software solutions that simplify and enhance the mobile experience to some of the leading wireless service providers around the globe. From enabling the Digital Family Lifestyle™ to providing powerful voice messaging capabilities, we strive to enrich today’s connected lifestyles while creating new opportunities to engage consumers via smartphones and consumer IoT devices. Our portfolio includes family safety software solutions to support families in the digital age and a wide range of products for creating, sharing, and monetizing rich content, such as visual voice messaging, retail content display optimization and performance analytics on any product set.

In 2024, our revenues declined by 50% to $20.6 million, primarily driven by an $18.1 million decline in revenues in our Family Safety product line, coupled with a $2.3 million decline in ViewSpot revenues. The revenue decline was primarily associated with the impact of the loss of a Tier 1 Family Safety contract, which concluded in November 2023. The revenues associated with that customer accounted for approximately 36% of our total revenues for 2023 and we recognized no revenues related to that contract in 2024. Other factors impacting the decline in revenues were the losses of two ViewSpot contracts, coupled with T-Mobile's efforts to migrate legacy Sprint subscribers to the T-Mobile network, which has impacted our revenues associated with legacy Sprint subscribers. As a result of the decrease in revenue, gross profit declined to $14.4 million in 2024, a decrease of $15.9 million compared to the prior year. To address the impact of that Tier 1 Family Safety contract termination, starting in the first quarter of 2023 and continuing in 2024, we undertook multiple restructuring efforts that have resulted in the elimination of approximately 48% of the Company's global workforce. While operating expenses increased in 2024 by approximately $15.5 million, the increase was primarily due to a non-cash goodwill impairment charge of $24.0 million. We realized year-over-year reductions in Research and Development, Sales and Marketing and General and Administrative expenses of $3.1 million, $2.2 million and $2.2 million, respectively, as a result of the cost reduction efforts undertaken. These decreases resulted in an 18% reduction in operating expenses, excluding goodwill impairment, in 2024 as compared to 2023, which follows a 26% reduction in operating expenses in 2023 as compared to 2022. The net loss for 2024 was $48.7 million, resulting in a net loss of $3.94 per basic and diluted share.

We believe that we remain strategically positioned to offer our market-leading family safety platform to the majority of U.S. mobile subscribers as we provide white-label Family Safety applications to two Tier 1 wireless carriers operating in the United States. Further, a Tier 1 carrier in Europe launched a new SafePath-based family safety solution in the fourth quarter of 2024 and began conducting robust marketing activities related to that solution during the first quarter of 2025. We believe that we have an opportunity to increase the respective subscriber bases, and in turn, grow the revenues associated with these Tier 1 carriers. In addition, with the recent expansion of our SafePath product line, most notably with SafePath Kids and SafePath OS, we believe that we are well-positioned to grow our Family Safety revenues more broadly with these Tier 1 carriers as well as with other operators in our industry.

Refer to section titled "Liquidity and Capital Resources" for discussion of significant material changes in cash and Note 7 of our Notes to the Consolidated Financial Statements for discussion regarding the changes related to the notes payable, derivative liabilities, and warrant liabilities.

The following table sets forth certain consolidated statement of operations data as a percentage of total revenues for the periods indicated:

The following is a description of the primary components of our revenues and expenses:

Revenues. Revenues are net of allowances. Our operations are organized into one business segment, Wireless, which includes all of our existing core products, including the Family Safety (including SafePath), CommSuite, and ViewSpot portfolio of products.

Cost of revenues. Cost of revenues consists of direct product and hosting, maintenance, data center, royalties, and technical support expenses including personnel costs.

Selling and marketing. Selling and marketing expenses consist primarily of personnel costs, advertising costs, including digital marketing expenses, sales commissions, and trade show expenses. These expenses may vary significantly from quarter to quarter based on the timing of trade shows and product introductions.

Research and development. Research and development expenses consist primarily of personnel costs, equipment costs, and external contract development costs required to conduct our software development efforts.

General and administrative. General and administrative expenses consist primarily of personnel costs, professional services and fees paid for external service providers, space and occupancy costs, and legal and other public company costs.

Depreciation and amortization. Depreciation is the expensing of a fixed asset as it is used to reflect its anticipated deterioration. Amortization of intangible assets consists of the amortization expense based on the pattern of economic benefit generated from the use of the related assets.

Goodwill impairment. Goodwill impairment represents the charge recorded in the amount of the carrying value of the Company's single reporting unit exceeding its fair value.

Change in fair value of warrant and derivative liabilities. Change in fair value of warrant and derivative liabilities results from valuation related impacts to the warrant and derivative liabilities.

Loss on derecognition of debt. Adjustments to fair value at each period end as the result of installment payments extinguishing principal associated with the convertible notes, including derivatives.

Interest income (expense), net. Interest income is primarily related to interest earned on cash equivalents. Interest expense is primarily related to interest associated with our convertible notes and financing arrangements and the amortization of debt issuance costs and discount.

Other income (expense), net. Other income (expense), net is primarily related to fixed asset disposals and other non-operating gains or losses.

(Benefit) provision for income tax expense. Income tax (benefit) expense is primarily related to the provision for federal, state, and foreign taxes imposed upon our results of operations.

Revenues. Revenues were $20.6 million and $40.9 million for the years ended December 31, 2024 and 2023, respectively, representing a decrease of $20.3 million, or 50%. This decrease was driven by declines in Family Safety and ViewSpot revenues of approximately $18.1 million and $2.3 million, respectively. This decline in revenues was primarily as a result of the losses of a Family Safety contract with a Tier 1 carrier and two ViewSpot contracts, coupled with the migration of legacy Sprint customers onto the T-Mobile network, which has impacted our revenues associated with legacy Sprint subscribers for Family Safety.

Cost of revenues. Cost of revenues were $6.1 million and $10.6 million for the years ended December 31, 2024 and 2023, respectively. This decrease of approximately $4.4 million was primarily due to cost reduction efforts in 2024 and the year-over-year decline in revenue.

Gross profit. Gross profit was $14.4 million, or 70.2% of revenues, for the year ended December 31, 2024, compared to $30.3 million, or 74.2% of revenues, for the year ended December 31, 2023. The decrease of $15.9 million in gross profit was a result of the year-over-year decline in revenue volume.

Selling and marketing. Selling and marketing expenses were $8.9 million and $11.1 million for the years ended December 31, 2024 and 2023, respectively. This decrease of $2.2 million was primarily due to decreases in personnel related costs of $1.7 million coupled with a period-over-period decline in marketing costs of $0.6 million and a decrease in travel costs of $0.1 million, partially offset by an increase in stock-based compensation of approximately $0.3 million.

Research and development. Research and development expenses were $14.1 million and $17.1 million for the years ended December 31, 2024 and 2023, respectively. This decrease of approximately $3.1 million was primarily due to the decline in personnel-related costs of approximately $2.9 million associated with the workforce reduction efforts coupled with reductions in contractor costs of $0.2 million due to the substantial completion of SafePath migration efforts during 2023.

General and administrative. General and administrative expenses were $10.6 million and $12.8 million for the years ended December 31, 2024 and 2023, respectively. This decrease of $2.2 million was primarily related to declines in personnel-related costs of approximately $1.0 million associated with the workforce reduction efforts undertaken, a decrease in professional fees of approximately $0.2 million, a reduction in occupancy costs of approximately $0.4 million, and a decline in stock-based compensation of approximately $0.6 million.

Depreciation and amortization. Depreciation expense was $0.4 million and $0.6 million for the years ended December 31, 2024 and 2023, respectively. Amortization expense was $5.9 million and $6.8 million for the years ended December 31, 2024 and 2023, respectively. The total decrease in depreciation expense of approximately $0.2 million was primarily due to certain fixed assets that have now been fully depreciated. Amortization expense is recognized based on the pattern of economic benefit expected to be generated from the use of the intangible asset, and as such it decreased by approximately $0.9 million.

Goodwill impairment. An impairment charge was recorded during the first quarter of 2024 as a result of an interim triggering event leading to an analysis, whereby we concluded that the carrying value of our single reporting unit exceed its fair value by $24.0 million. We did not have a similar charge in the prior year.

Change in fair value of warrant and derivative liabilities. The change in fair value of warrant and derivative liabilities of $0.4 million and $4.2 million for the years ended December 31, 2024 and 2023, respectively, resulted from valuation related impacts to warrant and derivative liabilities including changes in stock price, risk-free interest rate, expected term, and expected volatility.

Loss on derecognition of debt. The loss recognized on derecognition of debt for the year ended December 31, 2023 was $4.0 million. This resulted from installment payments made on the convertible notes issued under the Note and Stock offering in August 2022 (the "Notes") in the form of shares, and the required derecognition of the net debt position related to that principal balance, including the derivative, and discounts. There was no commensurate loss in the year ended December 31, 2024 as the convertible notes were retired at maturity as of December 31, 2023.

Interest income (expense), net. Interest income, net was $0.1 million for the year ended December 31, 2024 and interest expense, net was $6.4 million for the year ended December 31, 2023. The period-over-period change in interest income (expense), net of $6.5 million was primarily related to the amortization of the discount and debt issuance costs and stated interest expense related to the Notes, which were fully retired effective December 31, 2023.

(Benefit) provision for income tax expense. Because of our cumulative loss position, the current provision for income tax expense consists of state income taxes, foreign tax withholdings, and foreign income taxes. After consideration of the Company’s cumulative loss position as of December 31, 2024, the Company retained a full valuation allowance related to its U.S.-based deferred tax assets of $70.2 million at December 31, 2024.

Our principal sources of liquidity are our existing cash and cash equivalents, and cash generated by operations. We have in the past also generated cash from equity and debt financings. Our primary needs for liquidity relate to working capital requirements for operations. Our working capital requirements will depend on many factors, including the ability to obtain sufficient subscribers, and therefore revenue, from our customers to cover the current level of operating expenses to achieve a level of profitability. As of December 31, 2024, our cash and cash equivalents were approximately $2.8 million and we had no outstanding debt. Our cash flow used in operations was $14.3 million for the year ended December 31, 2024. Our cash balance as of December 31, 2024 was impacted by our transition to a new payment platform with our largest customer, which delayed the receipt of cash from this customer for certain invoices. We were subsequently able to collect $2.5 million of these aged receivables from that customer in January 2025. This delay in cash receipts was the primary driver of the increase in our accounts receivable balance to $5.7 million as of December 31, 2024 compared to $3.4 million as of September 30, 2024.

Our liquidity is being adversely impacted by the effect of the aforementioned loss during 2023 of our Family Safety contract with a Tier 1 carrier on our results of operations, since we recognized no revenue from that contract during 2024. While we have adjusted our cost structure and we expect to generate additional revenues from our recent launch with a Tier 1 carrier in Europe, the timing of that anticipated revenue growth versus the current impact of that contract loss could cause the cash and cash equivalents on hand and expected to be generated in the next twelve months and beyond to be insufficient to fund operations at the current levels.

This adverse impact on liquidity does not trigger a violation of any covenants in our material agreements, particularly as all of our outstanding debt was retired as of December 31, 2023. The availability of sufficient funds will depend to an extent on the timing of subscriber growth and the related cash generation thereof, and/or the ability to obtain the necessary capital to meet our obligations and fund our working capital requirements to maintain normal business operations. However, to meet future cash needs, the Company may determine to take additional actions, as noted in our Risk Factor "If we are unable to meet our obligations as they become due over the next twelve months, the Company may not be able to continue as a going concern." There can be no assurance that any such potential actions will be available or will be available on satisfactory terms. Our ability to obtain additional financing in the debt and equity capital markets is subject to several factors, including market and economic conditions, our performance and investor sentiment with respect to us and our industry. As a result of these uncertainties, and notwithstanding management's plans and efforts to date, we have been unable to alleviate substantial doubt about our ability to continue as a going concern within one year from the date that the financial statements are issued.

Changes in cash and cash equivalents are as follows:

Net cash used in operating activities was $14.3 million for the year ended December 31, 2024. The primary uses of operating cash were a net loss of $48.7 million less non-cash expenses totaling $33.9 million, including a goodwill impairment charge of $24.0 million, depreciation and amortization of $6.3 million and stock compensation expense of $4.5 million, coupled with a decrease in accounts payable and accrued liabilities of $1.9 million, partially offset by a decrease in accounts receivable of $2.2 million.

Net cash used in operating activities was $7.0 million for the year ended December 31, 2023. The primary uses of operating cash were a net loss of $24.4 million less non-cash expenses totaling $17.8 million, and a decrease in accounts payable and accrued liabilities of $2.8 million, partially offset by a decrease in accounts receivable of $2.6 million.

Net cash provided by investing activities of $0.2 million for the year ended December 31, 2024 was primarily attributable to the net proceeds from licensing several of our patents. Net cash used in investing activities was $0.1 million for the year ended December 31, 2023.

Net cash provided by financing activities of $9.8 million for the year ended December 31, 2024 was attributable to the net cash proceeds of $9.8 million from the offerings conducted in May 2024 and October 2024.

Net cash used by financing activities of $0.1 million for the year ended December 31, 2023 was primarily attributable to the timing of borrowings and repayments from short-term insurance premium financing arrangements.

During our normal course of business, we have made certain indemnities, commitments, and guarantees under which we may be required to make payments in relation to certain transactions. These include: intellectual property indemnities to our customers and licensees in connection with the use, sale and/or license of our products; contractual indemnities to our customers for breach of covenants, representations and warranties with respect to end user data privacy obligations; indemnities to various lessors in connection with facility leases for certain claims arising from such facility or lease; indemnities to vendors and service providers pertaining to claims based on negligence or willful misconduct; indemnities involving the accuracy of representations and warranties in certain contracts; and indemnities to directors and officers of the Company to the maximum extent permitted under the laws of the State of Delaware. We may also issue a guarantee in the form of a standby letter of credit as security for contingent liabilities under certain customer contracts. The duration of these indemnities, commitments and guarantees varies, and in certain cases, may be indefinite. The majority of these indemnities, commitments and guarantees may not provide for any limitation of the maximum potential for future payments we could be obligated to make. We have not recorded any liability for these indemnities, commitments and guarantees in the accompanying consolidated balance sheets.

See Note 1 of our Notes to Consolidated Financial Statements for information regarding recent accounting pronouncements.

As of December 31, 2024, we did not have any off-balance sheet arrangements.

Our discussion and analysis of results of operations, financial condition, and liquidity are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may materially differ from these estimates under different assumptions or conditions. On an on-going basis, we review our estimates to ensure that they appropriately reflect changes in our business or new information as it becomes available.

We believe the following critical accounting policies affect our more significant estimates and assumptions used in the preparation of our consolidated financial statements:

We apply the provisions of Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic No. 805, Business Combinations, in the accounting for our acquisitions, which requires recognition of the assets acquired and the liabilities assumed at their acquisition date fair values, separately from goodwill. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the tangible and identifiable intangible assets acquired and liabilities assumed. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period that exists up to twelve months from the acquisition date, we may record adjustments to the tangible and specifically identifiable intangible assets acquired and liabilities assumed with a corresponding adjustment to goodwill in the reporting period in which the adjusted amounts are determined. Upon the conclusion of the measurement period or final determination of the values of assets acquired and liabilities assumed, whichever comes first, the impact of any subsequent adjustments is included in the consolidated statements of operations.

Costs to exit or restructure certain activities of an acquired company or our internal operations are accounted for as a one-time termination and exit costs pursuant to FASB ASC Topic No. 420, Exit or Disposal Cost Obligations, and are accounted for separately from the business combination. A liability for costs associated with an exit or disposal activity is recognized and measured at its fair value in our consolidated statement of operations in the period in which the liability is incurred.

Uncertain income tax positions and tax-related valuation allowances that are acquired in connection with a business combination are initially estimated as of the acquisition date. We reevaluate these items quarterly based upon facts and circumstances that existed as of the acquisition date, with any adjustments to the preliminary estimates being recorded to goodwill if such adjustments occur within the 12-month measurement period. Subsequent to the end of the measurement period or our final determination of the value of the tax allowance or contingency, whichever comes first, changes to these uncertain tax positions and tax-related valuation allowances will affect the provision for income taxes in the consolidated statement of operations and could have a material impact on results of our operations and financial position.

We measure and disclose fair value measurements as required by FASB ASC topics.

•Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

•Level 2 - Include other inputs that are directly or indirectly observable in the marketplace.

•Level 3 - Unobservable inputs which are supported by little or no market activity.

We measure our cash equivalents at fair value. Our cash equivalents and short-term investments are classified within Level 1 by using quoted market prices utilizing market observable inputs.

For warrant liabilities and derivatives, we may utilize fair value measurements which are categorized within Level 3 of the fair value hierarchy, and subsequent changes in fair value for designated items are required to be reported in earnings in the current period.

For goodwill and other intangibles impairment analysis, we may utilize fair value measurements which are categorized within Level 3 of the fair value hierarchy.

Long-lived assets to be held are reviewed for events or changes in circumstances which indicate that their carrying value may not be recoverable. They are tested for recoverability using undiscounted cash flows to determine whether or not impairment to such value has occurred as per ASC Topic No. 360, Property, Plant, and Equipment.

Goodwill represents purchase consideration from a business combination that exceeds the value assigned to the net assets of the acquired businesses. As per Topic No. ASC 350, Intangibles- Goodwill and Other, we are required to periodically assess the recoverability of the carrying value of our goodwill at least annually during the fourth quarter of the fiscal year or whenever events or circumstances indicate a potential impairment. If the carrying amount of our single reporting unit exceeds its fair value, an impairment loss equal to the excess of carrying value over fair value is recorded.

We have no indefinite-lived intangible assets. Amortization expense related to our definite-lived intangible assets resulting from acquisitions is calculated based on the pattern of economic benefit expected to be generated from the use of that asset. Intangible assets are tested for impairment if events or circumstances occur indicating that the respective asset might be impaired in accordance with ASC Topic No. 350, Intangibles- Goodwill and Other and ASC 360, Property, Plant and Equipment.

In connection with preparing our consolidated financial statements, management evaluates whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern within one year from the date that the financial statements are issued.

In accordance with FASB ASC Topic No. 606, Revenue from Contracts with Customers, we recognize the sale of goods and services based on the five-step analysis of transactions as provided in Topic 606, which requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods and services.

We transfer software licenses to our customers on a royalty free, non-exclusive, non-transferrable, limited use basis during the term of the agreement. In some instances, we perform integration services to ensure the software operates within our customer’s operating platforms as well as the operating platforms of the mobile devices used by their end customers, before transferring the license. Revenue related to these services is recognized at a point in time upon acceptance of the licensed software by the customer. We also earn usage-based revenue on our platforms. Usage based revenue is generated based on licenses used by our customers' active subscribers’ access and usage of our software licenses and cloud-based services on our platforms, the provision of hosting services, and revenue share based on media placements on our platform. We recognize our usage-based revenue when we have completed our performance obligation and have the right to invoice the customer. This revenue is generally recognized monthly. Finally, we ratably recognize revenue over the contract period when customers pay in advance of our service delivery.

We also provide consulting services in connection with our development of customer-specified functionality that are generally not on our software development roadmap. We recognize revenue from our consulting services upon delivery and acceptance by the customer of our software enhancements and upgrades. For certain customers we provide maintenance and technology support services for which the customer either pays upfront or as we provide the services. When the customer pays upfront, we record the payments as contract liabilities and recognize revenue ratably over the contract period as this is our stand ready performance obligation that is satisfied ratably over the maintenance and technology services period.

We have received upfront payments from customers from services to be provided under our ViewSpot contracts. The advance receipts were deferred and subsequently recognized ratably over the contract period. We also provide consulting services to configure new devices or ad hoc targeted promotional content for our customers upon request. These requests are driven by our customers’ marketing initiatives and tend to be short term “bursts” of activity. We recognize these revenues upon delivery of the configured promotional content to the cloud platform or upon certification of the new device.

We account for all stock-based payment awards made to employees and directors based on their fair values and recognizes such awards as compensation expense over the vesting period using the straight-line method over the requisite service period for each award as required by FASB ASC Topic No. 718, Compensation-Stock Compensation.

Our consolidated financial statements appear in a separate section of this Report beginning on page F-1.

None.

We conducted an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (“Exchange Act”)) as of December 31, 2024. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer determined that as of December 31, 2024, our disclosure controls and procedures were effective to ensure that the information required to be disclosed in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Our management is responsible for the integrity and objectivity of all information presented in this Report. The consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States of America and include amounts based on management’s best estimates and judgments. Management believes the consolidated financial statements fairly reflect the form and substance of transactions and that the consolidated financial statements fairly represent the Company’s financial position and results of operations for the periods and as of the dates stated therein.

The Audit Committee of the Board of Directors, which is composed solely of independent directors, meets regularly with our independent registered public accounting firm, SingerLewak LLP, and representatives of management to review accounting, financial reporting, internal control, and audit matters, as well as the nature and extent of the audit effort. The Audit Committee is responsible for the engagement of the independent auditors. The independent auditors have free access to the Audit Committee.

There have been no changes in our internal controls over financial reporting during the quarter ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Our management, including the Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) under the Exchange Act).

Our management, including the Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of December 31, 2024. Management based this assessment on criteria for effective internal control over financial reporting described in “Internal Control-Integrated Framework 2013” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management determined that, as of December 31, 2024, we maintained effective internal control over financial reporting.

None.

We have adopted a statement of policy on insider trading (the “insider trading policy”) that describes our standards regarding the prohibition on trading, and causing the trading of securities while in possession of certain material nonpublic information, which we believe are reasonably designed to promote compliance with insider trading laws, rules and regulations, as well as any listing standards applicable to the Company (including Nasdaq listing standards). Our insider trading policy is applicable to all of our directors, officers and employees. The policy attempts to establish standards that will avoid even the appearance of improper transactions on the part of insiders to preserve the Company’s reputation for adhering to the highest standards of conduct.

The insider trading policy, among other things, prohibits trading in Company securities or “tipping” on the basis of or while in possession of material nonpublic information about the Company. These guidelines also provide certain specific exceptions for various transactions including, for example, (i) stock option exercises where no sale is made, (ii) the vesting of restricted stock awards or tax withholding requirements in connection therewith, (iii) bona fide gifts of securities, and (iv) Rule 10b5-1 plans. The insider trading policy further restricts trading and other transactions by our directors, officers and employees during certain “blackout periods” that follow the end of a given fiscal period.

Our insider trading policy further acknowledges that short sales, buying or selling publicly traded options, hedging transactions in the Company’s stock, margin accounts, and pledged securities may permit a holder to continue to own our common stock obtained through benefit plans or otherwise, but without the full risks and rewards of ownership. When that occurs, those participating in such transactions may no longer have the same objectives as our other stockholders. As such, the Company’s directors, officers and employees are prohibited from engaging in such transactions (except as otherwise may be approved in writing by the Company).

A copy of the Smith Micro Software, Inc. insider trading policy is filed as Exhibit 19.1 to this Report.

During the fiscal quarter ended on December 31, 2024, no director or officer of the Company adopted or terminated any “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.”

Pursuant to the requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, the registrant has duly caused this Report to be signed on its behalf by the undersigned thereunto duly authorized.

Pursuant to the requirements of the Securities Exchange Act of 1934, this Report has been signed below by the following persons on behalf of the registrant and in the capacities and on the dates indicated.

To the Stockholders and the Board of Directors of Smith Micro Software, Inc.

We have audited the accompanying consolidated balance sheets of Smith Micro Software, Inc. and its subsidiaries (collectively, the Company) as of December 31, 2024 and 2023, the related consolidated statements of operations, stockholders’ equity and cash flows, for the years then ended and the related notes to the consolidated financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the financial statements, the Company has suffered recurring losses from operations and has projected future cash flow requirements to meet continuing operations in excess of current available cash. This raises substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters also are described in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

The Company recognizes revenue upon transfer of control of promised services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those services. The Company primarily sells software solutions, cloud-based services and consulting services to major wireless network operators.

Significant judgement is exercised by the Company in determining revenue recognition, and includes the following:

•Determination of whether promised services are capable of being distinct and are distinct in the context of the Company’s customer contracts which leads to whether they should be accounted for as individual or combined performance obligations.

•Determination of prices for each distinct performance obligation, including for products and services sold separately.

•Determination of the timing of when revenue is recognized for each distinct performance obligation either over time or at a point in time.

We identified revenue recognition as a critical audit matter because of the significant judgements required by management. This required a high degree of auditor judgement and an increased extent of effort when performing audit procedures to evaluate whether revenue was appropriately recognized.

Our audit procedures related to the Company’s revenue recognition included the following, among others:

•We selected a sample of recorded revenue transactions and performed the following procedures:

•Obtained an understanding of management’s processes and controls related to revenue recognition.

•Obtained customer source documents and agreed them against the respective contract, related amendments, if any, or Statement of Work, if applicable, for each selection, to test if the contractual terms of the agreement have been appropriately applied to each selection.

•Evaluated management’s application of each step within the revenue accounting guidance and tested revenue recognition for specific performance obligations, including the allocation of pricing.

•Tested the mathematical accuracy of management’s calculations of revenue and associated timing of revenue recognized in the financial statements.

As of December 31, 2024, the Company’s goodwill, net was $11.0 million. The Company has a single reporting unit and performs an impairment test of goodwill at least annually during the fourth quarter or whenever events or circumstances indicate the carrying amount may not be recoverable. Due to a triggering event in February 2024, the Company determined it was necessary to perform a quantitative impairment assessment of goodwill as of February 29, 2024, by estimating the fair value of the reporting unit. The Company utilized weighted discounted cash flow and market-based valuation models to determine the fair value using significant assumptions such as discount rate, forecasted revenue, gross margin and operating expense projections, and comparable entity industry data. Based on the quantitative assessment performed, the Company concluded that the goodwill was impaired and recorded a $24.0 million charge. For the annual assessment date of December 31, 2024, the Company elected to perform a quantitative impairment test using the weighted discounted cash flow and market-based valuation models to determine the fair value using significant assumptions such as discount rate, forecasted revenue, gross margin and operating expense projections, and comparable entity industry data and concluded that the estimated fair value exceeded the carrying value of the assets and liabilities as of December 31, 2024, and as such there was not any further impairment of goodwill recorded in the fiscal year.

We identified the estimation of fair valuation of goodwill as a critical audit matter because of certain significant assumptions used by management in determining the estimate, including revenue, and expenses projections and the discount rate. Auditing management’s assumptions of revenue revenues, gross margin and operating expense projections and the discount rate involved a high degree of auditor judgment and increased audit effort, including the use of a valuation specialist, as changes in these assumptions could have a significant impact on the fair value of the reporting unit potential impairment charges.

Our audit procedures related to the Company’s goodwill impairment analysis included the following, among others:

•Obtained an understanding of management's processes and controls related to the Company's impairment analysis and determination of the fair value estimates.

•Evaluated the reasonableness of management's significant assumptions and underlying data used in the valuation models such as forecasted revenues, gross margin and operating expense projections by comparing management's prior forecasts to historical results.

•Performed a sensitivity analysis on the quantitative amounts utilized in evaluating the valuation.

•Evaluated management's significant accounting policies related to impairment of goodwill for reasonableness, including the determination of a single reporting unit.

•Utilized a valuation professional with specialized skills and knowledge to assist in:

▪Evaluating the appropriateness of the selection and application of the income and market-based valuation models, including selection of discount rates, weighted average cost of capital and long-term growth rate;

▪Testing the mathematical accuracy of the significant calculations in the valuation models;

▪Determining the reasonableness of the selection of discount rates, long-term growth rate range and multiples using publicly available market data.

We have served as the Company’s auditor since 2005.

On April 3, 2024, the Company filed a certificate of amendment to its Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware to effect a one-for-eight (1:8) reverse stock split of the shares of the Company's common stock, par value $0.001 per share (the "Common Stock"), with an effective time of 11:59 p.m., Eastern Time on April 10, 2024 (the "Reverse Stock Split"). At the effective time, every eight shares of common stock, whether issued and outstanding or held by the Company as treasury stock were automatically combined and converted (without any further act) into one share of fully paid and nonassessable common stock, with any fractional shares resulting from the Reverse Stock Split rounded up to the nearest whole share. The number of outstanding shares of common stock was reduced from approximately 76.8 million shares to approximately 9.6 million shares due to the Reverse Stock Split.

The Reverse Stock Split did not change the Company's authorized shares of common stock from 100,000,000 shares or the par value of the common stock, and, therefore, the Company reclassified an amount equal to the reduction in the number of shares of common stock at par value to additional paid-in-capital. Proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise of stock options and the settlement of restricted stock awards and the number of shares authorized and reserved for issuance pursuant to the Company's equity incentive plans (see Note 11). Additionally, there were adjustments to the per share exercise price and the number of shares issuable upon exercise of warrants (see Note 5).

All share and per share amounts for common stock (including share amounts underlying convertible securities and the applicable exercise prices of such convertible securities) in these consolidated financial statements and notes thereto have been retroactively adjusted for all periods presented to give effect to the Reverse Stock Split, including reclassifying an amount equal to the reduction in the number of shares of common stock at par value to additional paid-in capital.

The accompanying consolidated financial statements reflect the operating results and financial position of Smith Micro and its wholly owned subsidiaries in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). All intercompany amounts have been eliminated in consolidation.

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Certain reclassifications have been made to the prior year financial statements to conform to the current presentation.

During 2024 and 2023, the Company had a subsidiary or branch office in Serbia, Sweden, Portugal, and Slovakia. The functional currency for all of these foreign entities is the U.S. dollar in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 830. Foreign currency transactions that increase or decrease expected functional currency cash flows is a foreign currency transaction gain or loss that are included in determining net income for the period in which the exchange rate changes. Likewise, a transaction gain or loss (measured from the transaction date or the most recent intervening balance sheet date, whichever is later) realized upon settlement of a foreign currency transaction is included in determining net income for the period in which the transaction is settled.

The Company applies the provisions of FASB ASC Topic No. 805, Business Combinations, in the accounting for its acquisitions, which requires recognition of the assets acquired and the liabilities assumed at their acquisition date fair values, separately from goodwill. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the tangible and identifiable intangible assets acquired and liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period that exists up to twelve months from the acquisition date, the Company may record adjustments to the tangible and specifically identifiable intangible assets acquired and liabilities assumed with a corresponding adjustment to goodwill in the reporting period in which the adjusted amounts are determined. Upon the conclusion of the measurement period or final determination of the values of assets acquired and liabilities assumed, whichever comes first, the impact of any subsequent adjustments is included in the consolidated statements of operations.

Costs to exit or restructure certain activities of an acquired company or the Company’s internal operations are accounted for as a one-time termination and exit cost pursuant to FASB ASC Topic No. 420, Exit or Disposal Cost Obligations, and are accounted for separately from the business combination. A liability for costs associated with an exit or disposal activity is recognized and measured at its fair value in the Company’s consolidated statement of operations in the period in which the liability is incurred.

Uncertain income tax positions and tax-related valuation allowances that are acquired in connection with a business combination are initially estimated as of the acquisition date. The Company reevaluates these items quarterly based upon facts and circumstances that existed as of the acquisition date, with any adjustments to the preliminary estimates being recorded to goodwill if such adjustments occur within the 12-month measurement period. Subsequent to the end of the measurement period or the Company’s final determination of the value of the tax allowance or contingency, whichever comes first, changes to these uncertain tax positions and tax-related valuation allowances will affect the provision for income taxes in the consolidated statement of operations and could have a material impact on results of operations and financial position.

Cash and cash equivalents generally consist of cash and money market funds. The carrying amount of cash and cash equivalents approximates fair value due to the short-term maturities of these instruments.

Smith Micro sells its products worldwide. The Company performs ongoing credit evaluations of its customers and adjusts credit limits based upon payment history, the customer’s current credit worthiness and various other factors, as determined by review of their current credit information. The Company continuously monitors collections and payments from its customers. The Company estimates credit losses and maintains an allowance based upon these estimates. While such credit losses have historically been within its estimated reserves, the Company cannot guarantee that it will continue to experience the same credit loss rates that it has in the past. If not, this could have an adverse effect on Smith Micro’s consolidated financial statements.

Equipment and improvements are stated at cost. Depreciation is computed using the straight-line method based on the estimated useful lives of the assets, generally ranging from three to seven years. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life of the asset or the lease term.

Development costs incurred in the research and development of new software products and enhancements to existing software products are expensed as incurred until technological feasibility has been established. The Company considers technological feasibility to be established when all planning, designing, coding, and testing has been completed according to design specifications. After technological feasibility is established, any additional costs are capitalized. Through December 31, 2024, software has been substantially completed concurrently with the establishment of technological feasibility; accordingly, no costs have been capitalized to date.

Long-lived assets to be held are reviewed for events or changes in circumstances which indicate their carrying value may not be recoverable. They are tested for recoverability using undiscounted cash flows to determine whether or not impairment to such value has occurred.

Goodwill represents purchase consideration from a business combination that exceeds the value assigned to the net assets of the acquired businesses. Smith Micro is required to periodically assess the recoverability of the carrying value of its goodwill at least annually during the fourth quarter of the fiscal year or whenever events or circumstances indicate a potential impairment. If the carrying amount of the Company’s single reporting unit exceeds its fair value, an impairment loss equal to the excess of carrying value over fair value is recorded.

The Company has no indefinite-lived intangible assets. Amortization expense related to the Company’s definite-lived intangible assets resulting from acquisitions is calculated based on the pattern of economic benefit expected to be generated from the use of that asset and reassessed as determined necessary. Intangible assets are tested for impairment if events or circumstances occur indicating that the respective asset might be impaired.

The Company analyzes all financial instruments with features of both liabilities and equity under FASB ASC Topic No. 480, Distinguishing Liabilities from Equity, and FASB ASC Topic No. 815, Derivatives and Hedging. Derivative and warrant liabilities are adjusted to reflect fair value at each period end, with any increase or decrease in the fair value being recorded in the Statements of Operations as adjustments to fair value.

In connection with preparing its consolidated financial statements, management evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern within one year from the date that the financial statements are issued.

In accordance with FASB ASC Topic No. 606, Revenue from Contracts with Customers, the Company recognizes the sale of goods and services based on the five-step analysis of transactions as provided in Topic 606, which requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods and services.

Smith Micro primarily sell its software solutions, cloud-based services and consulting services to major wireless network and cable operators. For all contracts with customers, the Company first identifies the contract which usually is established when a contract is fully executed by each party and consideration is expected to be received. Next, the Company identifies the performance obligations in the contract. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. The Company then determines the transaction price in the arrangement and allocates the transaction price, if necessary, to each performance obligation identified in the contract. The allocation of the transaction price to the performance obligations are based on the relative standalone selling prices for the goods and services contained in a particular performance obligation. The transaction price is adjusted for the Company’s estimate of variable consideration. The Company evaluates the total amount of variable consideration expected to be earned by using the expected value method, as the Company believes this method represents the most appropriate estimate for this consideration, based on historical service trends, the individual contract considerations, and its best judgment at the time.

The Company includes estimates of variable consideration in revenues only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company also generates the majority of its revenue on usage-based fees which are variable and depend entirely on customers’ use of perpetual licenses, transactions processed on the Company’s hosted environment, advertisement placements on the Company’s service platform, and activity on the Company’s cloud-based service platform.

Smith Micro grants certain software licenses to its customers on a royalty free, non-exclusive, non-transferable, limited use basis during the term of the agreement. In some instances, the Company performs integration services to ensure the software operates within its customer’s operating platforms as well as the operating platforms of the mobile devices used by their end customers, before transferring the license. Revenue related to these services is recognized at a point in time upon acceptance of the licensed software by the customer. The Company also earns usage-based revenue on its platforms. The Company’s contracts with the certain customers may include promises to transfer multiple products and services. Smith Micro’s cloud-based service includes a software solution license integrated with cloud-based services. Judgment is required to determine whether the software license is considered distinct and accounted for separately, or not distinct and accounted for together with the cloud service and recognized over time. Smith Micro does not allow its customers to take possession of the software solution, and since the utility of the license comes from the cloud-based services that are provided, the Company considers the software license and the cloud-based services to be a single performance obligation. Usage based revenue is generated based on licenses used by Smith Micro’s customer’s active subscribers’ access and usage of Smith Micro’s software licenses and cloud-based services on Smith Micro’s platforms, the provision of hosting services, and revenue share based on media placements on Smith Micro’s platform. Smith Micro recognizes usage-based revenue when the Company has completed its performance obligation and has the right to invoice the customer. This revenue is generally recognized monthly or quarterly. Finally, the Company ratably recognizes usage-based revenue over the contract period when customers pay in advance of service delivery.

Smith Micro also provides consulting services to develop customer-specified functionality that are generally not on its software development roadmap. The Company recognizes revenue from its consulting services upon delivery and acceptance by the customer of its software enhancements and upgrades. For certain customers the Company provides maintenance and technology support services for which the customer either pays upfront or as the Company provides the services. When the customer pays upfront, the payments are recorded as contract liabilities and revenue is recognized ratably over the contract period as this is the Company’s stand ready performance obligation that is satisfied ratably over the maintenance and technology services period.

The Company may receive upfront payments from customers from services to be provided under its ViewSpot contracts. Those advance receipts are deferred and subsequently recognized ratably over the contract period. Smith Micro also provides consulting services to configure new devices or ad hoc targeted promotional content for its customers upon request. These requests are driven by customers’ marketing initiatives and tend to be short term “bursts” of activity. These revenues are recognized upon delivery of the configured promotional content to the cloud platform or upon certification of the new device.

Smith Micro has made accounting policy elections to exclude all taxes by governmental authorities from the measurement of the transaction price, and since the Company’s standard payment terms are less than one year, the Company has elected the practical expedient not to assess whether a contract has a significant financing component.

Smith Micro owns the Intellectual Property and retains ownership when the Company licenses its customized software solutions for use by its customers. The Company is a principal in these transactions and as such revenue is recognized with respect thereto on a gross basis.

The Company accounts for all stock-based payment awards made to employees and directors based on their fair values and recognizes such awards as compensation expense over the vesting period using the straight-line method over the requisite service period for each award as required by FASB ASC Topic No. 718, Compensation-Stock Compensation.

The Company accounts for income taxes as required by FASB ASC Topic No. 740, Income Taxes. This Topic clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Topic also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The Topic requires an entity to recognize the financial statement impact of a tax position when it is more likely than not that the position will be sustained upon examination. The amount recognized is measured as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. In addition, the Topic permits an entity to recognize interest and penalties related to tax uncertainties either as income tax expense or operating expenses. The Company has chosen to recognize interest and penalties related to tax uncertainties as income tax expense.

The Company assesses whether a valuation allowance should be recorded against its deferred tax assets based on the consideration of all available evidence, using a “more likely than not” realization standard. The four sources of taxable income that must be considered in determining whether deferred tax assets will be realized are: (1) future reversals of existing taxable temporary differences (i.e., offset of gross deferred tax liabilities against gross deferred tax assets); (2) taxable income in prior carryback years, if carryback is permitted under the applicable tax law; (3) tax planning strategies; and (4) future taxable income exclusive of reversing temporary differences and carryforwards.

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures. The amendments in this update are intended to improve reportable segment disclosure requirements, through enhanced disclosures about significant segment expenses. The improved disclosure requirements apply to all public entities that are required to report segment information, including those with only reportable segment. In addition to the current requirements, the amendments require all segment profit or loss and asset disclosures to be provided on an annual and interim basis. The amendments are effective for fiscal years beginning after December 15, 2023 and will be effective for interim reporting periods beginning after December 15, 2024. The Company adopted ASU 2023-07 with no material effect on its consolidated financial statements other than the additional disclosure requirements which are included in Note 15.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which provides for improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. This guidance is effective for fiscal years beginning after December 15, 2024, and the adoption of this standard is not anticipated to have a significant impact on the Company's consolidated financial statements other than adding new disclosures, which the Company is currently evaluating.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40), which is intended to improve the decision-usefulness of expense information on public companies' income through disaggregation of relevant expense captions in the notes to the financial statements. This ASU is effective for fiscal years beginning after December 15, 2026 and interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of this ASU on the consolidated financial statements and related disclosures.

The Company's financial statements have been presented on the basis that it is a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. In connection with preparing consolidated financial statements for the year ended December 31, 2024, certain conditions in the Company's evaluation, considered in the aggregate, have raised substantial doubt about the Company's ability to continue as a going concern within one year from the date that the financial statements are issued, which has not been alleviated. The evaluation considered the Company's financial condition, including its liquidity sources, funds necessary to maintain the Company's operations considering the current financial condition, obligations, and other expected cash flows, and negative financial trends of recurring operating losses and negative cash flows.

The Company has no outstanding debt and is continuing operations and generating revenues in the normal course, however the Company is dependent, to an extent, on the timing of subscriber and revenue growth for its products and the related cash generation from that growth and/or the ability to obtain the necessary capital to meet its obligations and fund its working capital requirements to maintain normal business operations. Management believes that the actions presently being taken to implement the Company's business plan to expand subscriber growth, to acquire new customers, and to expand its offerings to existing customers to generate increased revenues, and, if necessary, to raise additional capital will support the Company's operations; as such the financial statements do not include any adjustments that may be necessary if the Company is unable to continue as a going concern. The Company believes, based on its history of being able to complete debt and equity financings, that it would be able to raise additional funds as necessary, through public or private equity offerings, including by filing one or more registration statements, through debt financings, or from a combination of these funding sources. However, it may not be able to secure such incremental capital in a timely manner or on favorable terms, if at all. To preserve liquidity, the Company may also take one or more of the following additional actions:

•Implement additional restructuring and cost reductions,

•Secure a revolving line of credit, if available,

•Dispose of one or more product lines and/or,

•Sell or license intellectual property.

While management believes that the Company’s plans for growing revenue and the other potential actions available to it would alleviate the conditions that raise substantial doubt, these strategies are not entirely within the Company’s control and cannot be assessed as being probable of occurring.

Equipment and improvements consist of the following (in thousands):

Depreciation and amortization expense on equipment and improvements was $0.4 million and $0.6 million for each of the years ended December 31, 2024 and 2023, respectively.

The carrying amount of goodwill and the accumulated impairment losses are as follows (in thousands):

Smith Micro reviews the recoverability of the carrying value of the Company's single reporting unit goodwill at least annually or whenever events or circumstances indicate a potential impairment. The annual impairment testing date is December 31 of each year.

Recoverability of goodwill is determined by comparing the estimated fair value of the reporting unit to the carrying value of the underlying net assets in the reporting unit. If the estimated fair value of a reporting unit is determined to be less than the carrying value, goodwill is deemed impaired, and an impairment loss is recognized to the extent that the carrying value of goodwill exceeds the fair value.

During the first quarter of 2023, management concluded that the written notice of termination of a U.S. Tier 1 customer agreement for the Company's family safety solution, as disclosed in Note 16 of the 2022 Form 10-K, represented a triggering event indicating possible impairment of goodwill and long-lived assets, including customer relationships intangible assets. The estimated fair value of the Company's reporting unit exceeded the carrying value as of February 2023, and as such there was not any impairment. For the annual assessment date of December 31, 2023, there was not any impairment of the Company’s goodwill.

In the first quarter of 2024, as a result of the sustained decrease in the Company's common stock share price and overall market capitalization subsequent to February 23, 2024, management concluded that a triggering event occurred, indicating goodwill may be impaired. The Company conducted a quantitative impairment test of its goodwill as of February 29, 2024 and as a result of this interim assessment, including the impact of the projections of revenue growth, earnings before interest taxes depreciation and amortization (“EBITDA”), and discount rates along with market multiples, the Company recorded a goodwill impairment charge totaling $24.0 million during the three months ended March 31, 2024. The fair value of the reporting unit was determined based on a combination of the income approach using estimated discounted cash flows and a market-based valuation methodology. The assessment utilized level 3 inputs including estimates of revenue growth, EBITDA contribution and discount rates. Subsequent to this impairment charge, the fair value of the Company's single reporting unit approximated its carrying value.

For the annual assessment date of December 31, 2024, the Company elected to perform a quantitative impairment test with a combination of the income approach using estimated discounted cash flows and a market-based approach and concluded that the estimated fair value exceeded the carrying value of the reporting unit as of December 31, 2024, and as such there was not any further impairment of goodwill recorded in the fiscal year. However, if projections are not achieved or specific valuation factors outside the Company's control, such as discount rates and continued economic and industry challenges, significantly change, goodwill could be subject to future impairment.

The following table sets forth the Company’s acquired intangible assets by major asset class as of December 31, 2024 and 2023, respectively (in thousands, except for useful life data):

The Company recorded amortization expense of $5.9 million and $6.8 million on intangible assets for the years ended December 31, 2024 and 2023, respectively.

Future amortization expense related to intangible assets as of December 31, 2024 are as follows (in thousands):

Late in the third quarter of 2023, the Company received notice of a termination of one of its ViewSpot contracts. Subsequently, in the fourth quarter of 2023, the Company was also informed by another ViewSpot customer that they would not enter into a further extension of their existing ViewSpot contract, which was expiring in December 2023. As part of this notice, that customer exercised its right to continued service for a transition period of up to 180 days beyond the expiration of this contract. As a result of these combined customer contract termination and expiration notifications, the Company reviewed its assets, including the customer relationship intangible asset, pertaining to ViewSpot and determined that the carrying amount of the asset group was not in excess of the fair value based upon undiscounted expected future cash flows. The Company then reassessed the lives associated with these assets and is amortizing the remaining customer relationship intangible based on the pattern of economic benefit expected to be generated from the use of that asset, which accelerated $0.9 million of amortization expense in 2023. There was no impairment of any intangible assets for the years ended December 31, 2024 or 2023.

On December 27, 2023, the Company received a notice from the Nasdaq Stock Market ("Nasdaq") that the Company was not in compliance with the $1.00 minimum bid price requirement for continued listing, as set forth in Nasdaq Listing Rule 5550(a)(2) (the "Minimum Bid Price Requirement"), as the closing bid price of the Company’s Common Stock had been below $1.00 per share for more than thirty (30) consecutive business days as of the date of that notice. The Company undertook a one-for-eight (1:8) reverse stock split (the “Reverse Stock Split”), which became effective April 10, 2024 at 11:59 pm Eastern time, to enable the Company to regain compliance with the Minimum Bid Price Requirement. On April 29, 2024, the Company received notice from Nasdaq that it had regained compliance with the Minimum Bid Price Requirement, and the matter is now closed.

On November 26, 2024, the Company received a notice from Nasdaq that the Company’s Common Stock did not meet the $1.00 minimum bid price requirement pursuant to the Minimum Bid Price Requirement, and in accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was provided an initial compliance period of 180 calendar days, or until May 26, 2025, to regain compliance with the Minimum Bid Price Requirement. On January 8, 2025, the Company received written notification from Nasdaq indicating that the Company’s Common Stock had a closing price at or greater than $1.00 per share for the last 10 consecutive business days, from December 23, 2024 to January 7, 2025, and that, as a result, the Company has regained compliance with the Minimum Bid Price Requirement and the matter is now closed.

On May 10, 2024, the Company entered into a securities purchase agreement with certain institutional and accredited investors relating to the registered direct offering and sale of an aggregate of 1,065,000 shares of the Company’s Common Stock at an offering price of $2.15 per share of Common Stock and pre-funded warrants (“Pre-Funded Warrants") to purchase up to 845,000 shares of Common Stock (the “Registered Direct Offering”). The Pre-Funded Warrants were purchased at a price of $2.149 per underlying share and had an exercise price of $0.001 per share and could be exercised at any time after their original issuance until such Pre-Funded Warrants were exercised in full. The shares of Common Stock and Pre-Funded Warrants (including the shares of Common Stock underlying the warrants) were offered by the Company pursuant to a prospectus supplement dated May 10, 2024, and accompanying prospectus dated May 12, 2022, in connection with a takedown from the Company’s shelf registration statement on Form S-3 (File No. 333-264667), which was declared effective by the SEC on May 12, 2022.

In a private placement on May 14, 2024, concurrent with the Registered Direct Offering, the Company also sold to the Purchasers unregistered warrants (the “Common Warrants”) to purchase up to an aggregate of 1,910,000 shares of Common Stock (the “Private Placement”). Each unregistered Common Warrant has an exercise price of $2.34 per share, is exercisable at any time beginning November 14, 2024 and will expire November 14, 2029. Both the Registered Direct Offering and the Private Placement closed on May 14, 2024.

Roth Capital Partners, LLC (“Roth”) acted as the exclusive placement agent for the Registered Direct Offering and the Private Placement pursuant to a placement agency agreement (the “Placement Agency Agreement”) dated May 10, 2024, by and between the Company and Roth, and a related engagement letter with Roth. Pursuant to the Placement Agency Agreement, on May 14, 2024 the Company issued to Roth warrants to purchase up to 133,700 shares of Common Stock (the “Placement Agent Warrants”), which represented 7.0% of the aggregate number of shares of Common Stock and Pre-Funded Warrants sold in the Registered Direct Offering. The Placement Agent Warrants are exercisable at any time beginning November 14, 2024, have an exercise price equal to $2.86, and expire November 16, 2026.

The shares of Common Stock underlying the Common Warrants and the Placement Agent Warrants (collectively referred to herein as the “Warrants”) were registered on a registration statement on Form S-1 (File No. 333-280542) filed with the SEC on June 27, 2024, which was declared effective by the SEC on July 10, 2024. Shares of Common Stock issued by the Company upon exercise of the Warrants may be resold by the holders pursuant to the prospectus dated July 11, 2024. The filings made by the Company in connection with the potential resale of the Common Stock underlying the Warrants were filed within the time period agreed by the parties in the Purchase Agreement.

The net cash proceeds to the Company, after deducting offering related expenses was $3.4 million. The Pre-Funded Warrants, Common Warrants, and Placement Agent Warrants were all assessed and recorded as equity instruments.

In 2024, all 845,000 Pre-Funded Warrants from the May Registered Direct Offering and Private Placement were exercised on a cashless basis resulting in the issuance of 844,061 shares of Common Stock. No other warrants were exercised during the twelve months ended December 31, 2024.

On October 3, 2024, the Company announced its completion of two securities offerings raising aggregate gross proceeds of $6.9 million: a registered offering of Common Stock and concurrent private placement of warrants exercisable for Common Stock with certain institutional and accredited investors (collectively, the “October 2024 RDO”), and an unregistered private placement transaction of Common Stock and warrants exercisable for Common Stock with William W. Smith Jr., the Company's Chief Executive Officer, a related party, who participated in the private placement through a trust for which he serves as co-trustee (the “October 2024 Private Placement”). The registered offering of 3,321,881 registered shares of the Company's Common Stock together with the concurrent private placement of unregistered warrants to purchase an equal number of shares of the Company’s Common Stock pursuant to the October 2024 RDO resulted in gross proceeds to the Company of approximately $3.9 million, including $0.2 million from another related party, prior to transaction expenses.

The October 2024 Private Placement transaction with the Company’s Chief Executive Officer of 2,575,107 unregistered shares of the Company's Common Stock together with unregistered warrants to purchase an equal number of shares of the Company’s Common Stock resulted in gross proceeds to the Company of approximately $3.0 million prior to transaction expenses. Both offerings were approved by an independent special committee of the Company's Board of Directors and were priced based on the market value of the offered securities, at a purchase price of $1.165 per share of Common Stock with a warrant exercise price of $1.04 per share of Common Stock. Each of the warrants issued in the October 2024 offerings was initially exercisable at any time beginning six months following its original issuance and expires five and one-half years from the initial issuance of the warrant. In January 2025, at the request of certain holders of the warrants issued in the October 2024 RDO, the Company provided all of the October 2024 RDO warrant holders the opportunity to amend their warrants to adjust the start of the warrant exercise period to January 9, 2025, and as a result a portion of the warrants issued in connection with the October 2024 RDO were so amended. No other terms were changed as a result of that amendment to certain of the warrants.

Pursuant to the terms of an agreement previously entered into with Roth, which expired on September 29, 2024, Roth received certain “tail” compensation in the form of a cash fee of $54,000. In addition, concurrent with the offerings, the Company issued to Roth a warrant to purchase up to 20,000 shares of the Company’s Common Stock (the “Roth Warrant”), which has substantially the same terms as the warrants issued in the registered offering, except that the Roth Warrant has an exercise price of $1.46 per share of Common Stock and will expire two-and-a-half years from the effective date of the October registered offering.

On October 21, 2024, the Company filed a definitive proxy statement for a Special Meeting of Stockholders to approve the issuance of the number of shares of the Company’s Common Stock that would cause William W. Smith, Jr. to beneficially own twenty percent or more of the Company, through the exercise of the warrants purchased in the unregistered private placement transaction. The shareholders approved this proposal on December 10, 2024.

On October 28, 2024, the Company filed a registration statement with the SEC (File No. 333-282858) registering the resale of the shares of stock issued in the October 2024 Private Placement and the shares of common stock issuable upon exercise of the warrants issued in the October 2024 RDO and the October 2024 Private Placement. This registration statement was declared effective by the SEC on November 8, 2024.

The net cash proceeds to the Company from both offerings, after deducting offering related expenses was $6.6 million. All warrants associated with these transactions were assessed and recorded as equity instruments.

On August 11, 2022, the Company entered into a Securities Purchase Agreement ("SPA") with certain accredited investors, and, pursuant to the SPA, sold a new series of senior secured convertible notes (the "Notes") with an aggregate original principal amount of $15.0 million and an initial conversion price of $26.80 per share, subject to adjustment as described in the Notes, and warrants to acquire up to an aggregate amount of 279,851 additional shares of the Company’s common stock (the "Notes Warrants" and together with the Notes, the "Notes and Warrants Offering"). The closing of the Notes and Warrants Offering occurred on August 11, 2022. The Notes accrued compounding interest at the rate of 6.0% per annum, which was payable in cash or shares of the Company's common stock at the Company's option, in arrears quarterly in accordance with the terms of the Notes. Upon the occurrence and during the continuance of an Event of Default (as defined in the Notes), the Notes would accrue interest at the rate of 15.0% per annum. Upon conversion and other designated events, holders of the Notes were also entitled to receive an interest make-whole payment. Upon a redemption due to a Change in Control (as defined in the Notes), holders of the Notes were entitled to cash settlement. The Notes matured on December 31, 2023, with amortization payments being made monthly from April 2023 through December 2023, and the balance at maturity, with a total of 2.1 million of shares transferred valued at a total of $19.1 million as of the dates conveyed. The entire balance of the note was repaid in 2023 and as such all of the debt and the related derivative were derecognized as of December 31, 2023. The Notes contained a make-whole feature and a redemption right payable in cash upon change in control feature, as well as certain other conversion and redemption features. These features were viewed as a compound embedded derivative that met the criteria to be bifurcated and carried at fair value. This was classified in the balance sheet line "Derivative liabilities" and as a discount on the Notes, with subsequent adjustments to fair value each reporting period with a charge to earnings.

The derivative was eliminated with the retirement of the notes on December 31, 2023. The following assumptions were utilized:

Given that the Notes Warrants and the derivative are liability instruments that are measured at fair value, the transaction proceeds were allocated first to the Notes Warrants and derivative, with the residual to the Notes. Transaction issuance costs for the Notes and Warrants Offering were allocated in the same manner, with $0.5 million relating to the Notes Warrants and derivative being expensed immediately in 2022 within "General and administrative expenses." Deferred financing costs for the Notes and Warrants Offering totaled $0.5 million and were reported net of accumulated amortization as a deduction from the face amount of the debt. Amortization of the deferred financing costs and discount was reported as a component of interest expense and is computed using the effective interest method over the expected term of the debt. In the Notes and Warrants Offering, the Company raised net cash proceeds of $14.0 million.

During the year ended December 31, 2023, the Company recognized interest expense of $6.6 million on the Notes and related instruments utilizing the effective interest rate of 155%, which includes amortization of debt issuance costs of $0.3 million, amortization of discount of $5.7 million, and contractual interest of $0.6 million. The Notes were retired at maturity on December 31, 2024, and as such there was no remaining amortization of debt issuance costs, amortization of discount, or contractual interest.

The Notes contained certain customary affirmative and negative covenants regarding the incurrence of indebtedness, acquisition and investment transactions, the existence of liens, the repayment of indebtedness, the payment of cash in respect of dividends, distributions or redemptions, and the transfer of assets, among other matters. Throughout the duration of the notes the Company was in compliance with all covenants

On August 11, 2022, the Company issued the Notes Warrants in conjunction with the Notes and Warrants Offering, at an initial fair value of $3.8 million. The exercise price of and number of shares underlying the Notes Warrants were immediately proportionately adjusted pursuant to the Reverse Stock Split to $26.80 and 279,851 shares, respectively, and on May 2, 2024, the exercise price for each of the Notes Warrants was further adjusted to $2.06 in accordance with their terms.

The Company issued additional warrants (the "Additional Warrants") to purchase Common Stock on August 12, 2022 in conjunction with a registered direct offering for the sale of shares of the Company's Common Stock and the Additional Warrants. The Additional Warrants do not reprice further beyond the immediate proportionate adjustments to the per share exercise price and number of shares issuable of $21.20 and 141,509 shares, respectively, that occurred upon and as a result of the Reverse Stock Split.

All changes in the fair value of the Notes Warrants and Additional Warrants liabilities are recognized in the Company's consolidated statements of operations until they are either exercised or expire. Since their issuance, none of the Notes Warrants or Additional Warrants have been exercised. The Notes Warrants and Additional Warrants are not traded in an active securities market and, as such, the estimated fair value is determined by using a Black-Scholes option pricing model which considers the likelihood of repricing adjustments and utilizes assumptions noted in the following table. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of valuation. Expected volatility is based on the historical volatility over the expected remaining term of the warrants. The Company has no reason to believe future volatility over the expected remaining life of the Notes Warrants and Additional Warrants is likely to differ materially from historical volatility. Expected life is based on the term of the applicable warrants. Below are the specific assumptions utilized:

The Company measures and discloses fair value measurements as required by FASB ASC Topic No. 820, Fair Value Measurements and Disclosures.

•Level 1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

•Level 2 – Include other inputs that are directly or indirectly observable in the marketplace.

•Level 3 – Unobservable inputs which are supported by little or no market activity.

The following table presents information about the financial liabilities that are measured at fair value on a recurring basis at December 31, 2024 and 2023 (in thousands):

The following table presents the changes in the fair value of Level 3 instruments for the years ended December 31, 2024 and 2023 (in thousands):

The carrying values for all other financial assets and liabilities approximated fair value for the years ended December 31, 2024 and 2023.

Loss before provision for income taxes was generated from the following sources (in thousands):

A summary of the income tax expense is as follows (in thousands):

A reconciliation of the provision for income taxes to the amount of income tax expense that would result from applying the federal statutory rate to the loss before income taxes is as follows:

The major components of the Company’s deferred tax assets and liabilities are as follows (in thousands):

The Company has federal net operating loss (“NOL”) carryforwards of approximately $207.3 million and state NOL carryforwards $180.9 million at December 31, 2024, and federal NOL carryforwards of $189.5 million and state NOL carryforwards of $136.2 million at December 31, 2023, to reduce future cash payments for income taxes. The federal NOL carryforwards generated prior to 2018 will expire from 2031 through 2037 and state NOL carryforwards will expire through 2041. Federal NOL carryforwards generated in 2018 and thereafter have no expiration date.

The Company has federal tax credit carryforwards of approximately $2.5 million at both December 31, 2024 and December 31, 2023. The Company has state tax credit carryforwards of $0.7 million at both December 31, 2024 and December 31, 2023 . These tax credits will begin to expire in 2028. To the extent that an ownership change has occurred under Internal Revenue Code Sections 382 and 383, the Company’s use of its loss carryforwards and credit carryforwards to offset future taxable income may be limited.

No ownership changes have occurred as of December 31, 2024.

At December 31, 2024 and 2023, the Company had unrecognized tax benefits, including interest and penalties, of approximately $0.4 million, with no changes in those balances.

The Company recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense, however during 2024 and 2023, the Company did not recognize any interest or penalties. There were no  cumulative interest or penalty amounts at December 31, 2024 and 2023. The Company does not anticipate any material changes to unrecognized tax benefits within the next twelve months that will affect the effective tax rate.

In assessing whether a valuation allowance is required, significant weight is given to evidence that can be objectively verified. Realization of deferred tax assets is dependent upon the generation of future taxable income. As required by ASC 740, Smith Micro has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax assets and determined that it was more likely than not that the Company would not realize the deferred tax assets due to the Company's cumulative losses and uncertain near-term market and economic conditions, which reduce the Company’s ability to rely on projections of future taxable income in assessing the realizability of its deferred tax assets.

After a review of the four sources of taxable income as of December 31, 2024 (as described in Note 1), and after consideration of the Company’s continuing cumulative loss position as of December 31, 2024, the Company recorded a valuation allowance related to its U.S.-based deferred tax assets of $70.2 million at December 31, 2024. The valuation allowance on deferred tax assets increased by $11.7 million and decreased by $4.2 million in 2024 and 2023, respectively.

The Company is subject to U.S. federal income tax as well as to income tax of multiple state jurisdictions. Currently there are no audits in process or pending from Federal or state tax authorities. The outcome of any tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income tax in the period such resolution occurs. As of December 31, 2024, a current estimate of the range of changes that may occur within the next twelve months cannot be made due to the uncertainty regarding the timing of these events.

For financial reporting purposes, income before provision for income taxes for the Company’s foreign subsidiaries was approximately $0.1 million for both years ended December 31, 2024 and 2023. Smith Micro does not provide for U.S. taxes on its unremitted earnings of foreign subsidiaries that have not been previously taxed since the Company intends to invest such undistributed earnings indefinitely outside of the U.S.

The 2017 US Tax Cuts and Jobs Act subjects a U.S. shareholder to current tax on global intangible low-taxed income (“GILTI”) earned by certain foreign subsidiaries. The Company's accounting policy is to recognize the tax on GILTI as a period expense in the period the tax is incurred. The current income related to the GILTI inclusion in 2024 is $1.1 million.

The Company calculates earnings per share (“EPS”) as required by FASB ASC Topic No. 260, Earnings Per Share. Basic EPS is calculated by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period, excluding common stock equivalents. Diluted EPS is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period, plus the weighted average number of dilutive common stock equivalents outstanding for the period using the treasury-stock method. For periods with a net loss, the dilutive common stock equivalents are excluded from the diluted EPS calculation. For purposes of this calculation, common stock subject to repurchase by the Company, options, warrants, and convertible notes are considered to be common stock equivalents, and are only included in the calculation of diluted earnings per share when their effect is dilutive.

The following table sets forth the details of basic and diluted earnings per share (in thousands, except per share amounts):

The following shares were excluded from the computation of diluted net loss per share as the impact of including those shares would be anti-dilutive (in thousands):

The Company offers its US employees participation in a 401(k) plan, in which the Company matches the employee contributions at a rate of 20%, subject to a vesting schedule. Total employer contributions amounted to $0.4 million and $0.5 million for the years ended December 31, 2024 and 2023, respectively.

On June 18, 2024, the Company's stockholders approved the Company's Amended and Restated Omnibus Equity Incentive Plan (the "OEIP") which amended and restated (and renamed) the Company's 2015 Omnibus Equity Incentive Plan (as previously amended, the "2015 Plan") and increased the number of shares reserved thereunder by 3.0 million shares. As of December 31, 2024, there were approximately 2.6 million shares available for future grants under the Company’s OEIP. References to the OEIP herein include the 2015 Plan prior to its amendment and restatement. The maximum number of shares available for issuance over the term of the OEIP may not exceed 4.2 million shares. During the year ended December 31, 2024, the Company granted 0.7 million shares of restricted stock under the OEIP.

The Company previously maintained a 2005 Stock Option/Stock Issuance Plan (the "2005 Plan"), which was replaced by the 2015 Plan. As of December 31, 2024, no options issued under the 2005 Plan remain outstanding, and no new grants have been made under the 2005 Plan.

The OEIP provides for the issuance of full value awards (restricted stock, performance stock, dividend equivalent right or restricted stock units) and partial value awards (stock options or stock appreciation rights) to employees, non-employee members of the board and consultants. Any full value award settled in shares will be debited as 1.2 shares, and partial value awards settled in shares will be debited as 1.0 shares against the share reserve. The exercise price per share for stock option grants is not to be less than the fair market value per share of the Company’s common stock on the date of grant.

The Board of Directors has the discretion to determine the vesting schedule. Stock options may be exercisable immediately or in installments, but generally vest over a four-year period from the date of grant. In the event the holder ceases to be employed by the Company, all unvested stock options terminate, and all vested stock options may be exercised within a period of 90 days following termination. In general, stock options expire ten years from the date of grant. Restricted stock is valued using the closing stock price on the date of the grant. The total value is expensed over the vesting period, which typically ranges from 12 to 48 months, however in the quarters ended September 30, 2024, March 31, 2024, and September 30, 2023, the Company granted restricted stock awards with tranched vesting period of two to seven months.

The Company accounts for all stock-based payment awards made to employees and directors based on their fair values and recognized as compensation expense over the vesting period using the straight-line method over the requisite service period for each award as required by FASB ASC Topic No. 718, Compensation-Stock Compensation.

Non-cash stock-based compensation expenses related to stock options, restricted stock grants and the ESPP (as defined below) were recorded in the financial statements as follows (in thousands):
