Investing in our common stock involves a high degree of risk, including the risks described below, each of which may be relevant to decisions regarding an investment in or ownership of our stock. The occurrence of any of these risks could have a significant adverse effect on our reputation, business, financial condition, revenue, results of operations, growth, or ability to accomplish our strategic objectives, and could cause the trading price of our common stock to decline. You should carefully consider the risks set forth below and the other information contained in this report, including our consolidated financial statements and related notes and Management's Discussion and Analysis of Financial Condition and Results of Operations, before making investment decisions related to our common stock. However, this report cannot anticipate and fully address all possible risks of investing in our common stock, the risks of investing in our common stock may change over time, and additional risks and uncertainties that we are not aware of, or that we do not consider to be material, may emerge. Moreover, some of the factors, events, and contingencies discussed below may have occurred in the past,past. butReferences theto disclosurespast belowevents are provided by way of example only and are not representationsintended to be a complete listing or representation as to whether or not the factors,such events or contingencies have occurred in the past,past or their likelihood of occurring in the future, and instead reflect our beliefs and opinions as to the factors, events, or contingencies that could materially and adversely affect us in the future. Accordingly, you are advised to consider additional sources of information and exercise your own judgment in addition to the information we provide.
Our business depends on the overall demand for advertising and on the economic health of our current and prospective sellers and buyers. If advertisers reduce their overall advertising spending, our revenue and results of operations are directly affected. Accordingly, our business and operations have been, and could in the future be, adversely affected by events beyond our control, such as health epidemics or pandemics, geopolitical events, and economic and macroeconomic factors like labor strikes, labor shortages, supply chain disruptions, tariffs, trade wars, capital market disruptions and instability of financial institutions, inflation and recessionary concerns impacting the markets and communities in which our clients operate.
In addition, continued inflation could result in an increase in our cost base relative to our revenue and increased cost associated with our infrastructure investments. Moreover, in response to US tariffs, foreign countries in which we operate may enact additional or new taxes that are applicable to our business.
We face intense competition in the marketplace. We compete for advertising spending against competitors that, in some cases, are also buyers and/or sellers on our platform. We also compete for supply of advertising inventory against a variety of competitors. Some of our existing and potential competitors are better established, benefit from greater name recognition, may have offerings and technology that we do not have or have significantly more financial, technical, sales, and marketing resources than we do. In addition, some competitors, particularly those with greater scale or a more diversified revenue base and a broader offering, have greater flexibility than we do to compete aggressively on the basis of price and other contract terms, or to compete with us by including in their product offerings services that we may not provide. Some existing and potential buyers that we work with have their own direct relationships with sellers or are seeking to establish such relationships, and many sellers are investing in capabilities that enable them to connect more effectively directly with buyers without the use of intermediaries such as us. Our business suffers to the extent that buyers and sellers purchase and sell advertising inventory directly from one another or through intermediaries other than us, reducing the amount of advertising spend on our platform. New or stronger competitors may emerge through acquisitions and industry consolidation or through development of disruptive technologies.technologies, including artificial intelligence (“AI”), which may disrupt the digital advertising ecosystem by enabling new ad-buying, optimization or monetization models or enhancing the capabilities of competitors. If our offerings are not perceived as competitively differentiated, we could lose clients, market share or be compelled to reduce our prices, making it more difficult to grow our business profitably.
As technology continues to improve and market factors continue to attract investment, competition and pricing pressure may increase and market saturation may change the competitive landscape in favor of larger competitors with greater scale and broader offerings, including those that can afford to spend more than we can to grow more quickly and strengthen their competitive position. Competition may be further impacted by advancements in artificial intelligence,AI, and our ability to compete in the future may be dependent, in part, on our ability to further develop artificial intelligenceAI into our solutions. In addition, our competitors or potential competitors may adopt certain aspects of our business model, which could reduce our ability to differentiate our solutions.
Sellers and buyers may seek to change the terms on which they do business with us, or allocate their advertising inventory or demand to our competitors who provide advertising demand and supply to them on more favorable terms or whose offerings are considered more beneficial. Supply of advertising inventory is also limited for some sellers, and sellers may request higher prices, fixed price arrangements or guarantees that we cannot provide as effectively as our competitors, or that would reduce the profitability of that business. In addition, sellers sometimes place significant restrictions on the sale of their advertising inventory, such as strict security requirements, limitations on data sharing, prohibitions on advertisements from specific advertisers or specific industries, and restrictions on the use of specified creative content or format. Buyers, in turn, are free to direct their spend to us or one or more of our competitors, and increasingly are seeking price concessions, rebates, or other consideration to direct more spend towards us.
We serve many buyers and sellers, but certain large buyers and sellers have accounted for and will continue to account for a disproportionate share of business transacted through our solution. In 2025, there were two buyers of advertising inventory that indirectly contributed to approximately 44% of revenue through their buying activity from sellers on our platform. If a buyer or group of buyers representing a significant portion of the demand in our marketplace, or a seller or group of sellers representing a significant portion of the inventory in our marketplace decides to materially reduce use of our solutions, it could cause an immediate and significant decline in our revenue and profitability and harm to our business. In addition, loss of substantial inventory or demand could degrade our marketplace. Loss of major DSP sources of demand could adversely affect bid density or pricing in our auctions, and reduction in fees if we are not able to redirect inventory to other demand sources. Loss of important unique inventory could reduce fees from demand that cannot be shifted to other sellers and make it harder to differentiate ourselves from our competitors. The number of large media buyers and sellers in the market is finite, and it could be difficult for us to replace the losses from any buyers or sellers whose relationships with us diminish or terminate.
Sellers and buyers may seek to change the terms on which they do business with us, or allocate their advertising inventory or demand to our competitors who provide advertising demand and supply to them on more favorable terms or whose offerings are considered more beneficial. Supply of advertising inventory is also limited for some sellers, such as special sites or new technologies, and sellers may request higher prices, fixed price arrangements or guarantees that we cannot provide as effectively as our competitors, or that would reduce the profitability of that business. In addition, sellers sometimes place significant restrictions on the sale of their advertising inventory, such as strict security requirements, limitations on data sharing, prohibitions on advertisements from specific advertisers or specific industries, and restrictions on the use of specified creative content or format. Finally, with the proliferation of header bidding in desktop and mobile, sellers' inventory is available for purchase through multiple exchanges simultaneously. Buyers, in turn, are free to direct their spend to us or one or more of our competitors, and increasingly are seeking price concessions, rebates, or other consideration to direct more spend towards us.
We serve many buyers and sellers, but certain large buyers and sellers have accounted for and will continue to account for a disproportionate share of business transacted through our solution. In 2024, there were two buyers of advertising inventory that indirectly contributed to approximately 39% of revenue through their buying activity from sellers on our platform. If a buyer or group of buyers representing a significant portion of the demand in our marketplace, or a seller or group of sellers representing a significant portion of the inventory in our marketplace decides to materially reduce use of our solutions, it could cause an immediate and significant decline in our revenue and profitability and harm to our business. In addition, loss of substantial inventory or demand could degrade our marketplace. Loss of major DSP sources of demand could adversely affect bid density or pricing in our auctions, and reduction in fees if we are not able to redirect inventory to other demand sources. Loss of important unique inventory could reduce fees from demand that cannot be shifted to other sellers and make it harder to differentiate ourselves from our competitors. The number of large media buyers and sellers in the market is finite, and it could be difficult for us to replace the losses from any buyers or sellers whose relationships with us diminish or terminate.
In light of these challenges, programmatic CTV has largely been transacted through reserve auctions. Reserve auctions allow publishers to establish direct deals with a buyer, and may be "guaranteed," where a buyer has negotiated a pre-established price and volume with a seller. These transaction types allow the seller to maintain tighter control over their advertising allocation and are often used by sellers that maintain a direct sales force but still want to experience the benefits of automation. In general, advertising impressions monetized through reserve auctions carry a lower fee than impressions monetized through auctions with multiple bidders. Accordingly, an increase in the percentage of CTV inventory monetized through reserve auctions, at the expense of biddable auctions, could drive a decrease in our overall take rate (our fee as a percentage of advertising spend) which may negatively impact our growth.
Our success requires us to maintain and expand our access to premium and unique advertising inventory. We do not own or control the ad inventory upon which our business depends and do not own or create content. Sellers are generally not required to offer a specified level of inventory on our platform, and we cannot be assured that any publisher will continue to make their ad inventory available on our platform. Sellers may seek to change the terms on which they offer inventory on our platform, including with respect to pricing, may elect to make advertising inventory available to our competitors who offer more favorable economic terms, may create their own ad-tech solutions, or may connect with buyers directly. Sellers may also require us to take increased risks in some of our commercial agreements in the form of offering revenue guarantees or minimum spend commitments, and we may be subject to losses if we cannot meet these guarantees or commitments. Furthermore, sellers may enter into exclusive relationships with our competitors or with DSPs directly, which may precludelimit us from offering their inventory.
The digital advertising market, and our business, may be negatively impacted by advancements in AI.
Advancements in AI present both opportunities and risks to our business, particularly within the context of the open internet and display advertising. AI is changing the way in which users access information and content on the open internet, in particular with respect to search referral traffic, which has and is expected to continue to decline. This shift could create challenges for open web publishers that have relied on advertising to support their business models. Furthermore, the rapid evolution of AI technologies could lead to diminishing demand for display advertising or reallocating budgets to new formats and approaches, including walled-gardens that we cannot access. If we are unable to capture this demand through other channels, adapt to evolving market expectations, or compete effectively with AI-driven ecosystems, our growth and market position could be adversely impacted.
AI may significantly affect the competitive dynamics of our industry, and failure to effectively build AI features into our platform could adversely affect our results of operations.
The market for programmatic advertising is characterized by rapid technological change and intense competition. We face significant pressure from existing competitors and new market entrants who are increasingly leveraging AI to enhance their platforms. If our competitors or other third parties, including those with greater financial and technical resources, incorporate AI into their offerings more quickly or effectively than we do, our platform may become less attractive to buyers and sellers of digital advertising. Any failure on our part to successfully develop and deploy AI solutions into our platform could result in a loss of market share.
Moreover, emerging AI–driven programmatic advertising protocols and transaction frameworks may not be interoperable with, or may reduce reliance on, existing industry standards and infrastructure, which could disrupt established buying and selling workflows. If we are unable to adapt our technology or influence the adoption of such protocols, it could adversely affect demand for our platform and our market share. If we fail to anticipate and adequately respond to these AI-driven structural shifts, our competitive position and ability to maintain a leading independent marketplace may be compromised.
We may be ineffective in using AI to realize internal efficiencies, which could result in higher operating costs and decreased margins.
We currently incorporate AI solutions into our product offerings and internal workflows, and we expect the use of AI to become increasingly central to our operations over time. However, our ability to realize the anticipated benefits of these technologies is subject to significant risks and uncertainties. We may fail to effectively leverage internal AI solutions to automate manual processes, optimize our infrastructure or enhance the productivity of our team.
If we are unable to realize the cost savings or operational improvements we anticipate from AI, our margins may be negatively impacted. Furthermore, the implementation of AI-driven internal tools requires significant investment in talent and infrastructure; if these investments do not yield a corresponding increase in productivity or a reduction in legacy costs, our financial condition and results of operations could be adversely affected. Additionally, any over-reliance on AI for critical business functions without adequate human oversight could lead to operational errors, data inaccuracies, or inefficiencies that could harm our reputation and competitive position.
The regulatory landscape governing AI is still developing, and our use of third party AI tools may result in increased legal and regulatory scrutiny, litigation, and reputational harm.
The regulatory landscape governing AI is highly uncertain and rapidly evolving. We face potential risks from new or enhanced governmental oversight and evolving legal standards regarding the use of AI.
The integration of third-party AI models with our products and services relies on certain safeguards implemented by the third-party developers of the underlying AI models. If the content, analyses, or recommendations that AI applications assist in producing are or are alleged to be inaccurate, deficient, or biased, our business and reputation may be adversely affected.
Additionally, AI applications generally state they do not use personal data or other classes of protected data, but we may not know the source of data used by an AI application and may inadvertently incorporate personal information, or data derived from personal data, in the course of using an AI application. Any such inclusion could lead to violations of global privacy laws, such as the GDPR or CCPA, and result in significant fines or legal action.
The use of AI also presents unique cybersecurity and intellectual property risks. Our use of AI tools could lead to cybersecurity incidents or the unauthorized public disclosure of our intellectual property. Moreover, malicious actors may increasingly use AI to develop more sophisticated and automated cyberattacks against our infrastructure.
If we are unable to minimize unintended harmful impacts of AI or fail to adapt to new AI-specific regulations, our competitive position and financial condition may be materially and adversely affected.
In addition, in order to achieve increased advertising spend or prevent loss of business to a competitor, we may negotiate discounts, rebates, or similar incentives with advertisers or agencies.agencies, which we may be unable to recoup. We believe that because our business has many fixed costs, increases in advertising spend volume generally create opportunities to disproportionately improve our bottom line results, even with increased discounts, rebates or other buyer incentives. However, our results could be negatively impacted by discounts, rebates and other buyer incentives, notwithstanding an increase in ad spend.
We face intense competition in the marketplace and are confronted by rapidly changing technology (including advancements in artificial intelligenceAI), evolving industry standards and consumer needs, regulatory changes, and the frequent introduction of new solutions by our competitors to which we must adapt and respond. Our future success will depend in part upon our ability to enhance our existing solution and to develop and introduce competing new solutions in a timely manner with features and pricing that meet changing client and market requirements. Our solutions are complex and require a significant investment of time and resources to develop, test, introduce, and enhance. We schedule and prioritize our development efforts according to a variety of factors, including our perceptions of market trends, client requirements, and resource availability; however, we may encounter unanticipated difficulties that require us to re-direct, scale back, or modify our efforts. If development of our solution becomes significantly more expensive due to changes in regulatory requirements or industry practices, or other factors, we may find ourselves at a disadvantage to larger competitors with more resources to devote to development. These factors place significant demands upon our engineering organization, require complex planning, and can result in acceleration of some initiatives and delay of others. We use outsourced software development for certain development efforts, which may put the company at greater risk with respect to our technology development because we may have less control over the performance of outside programmers and we may be at greater risk of losing their services. To the extent we do not manage our development efforts efficiently and effectively, we may fail to produce solutions that respond appropriately to the needs of buyers and sellers, and competitors may more successfully develop responsive offerings. If our solution is not competitive, buyers and sellers can be expected to shift their business to competing solutions. Buyers and sellers may also resist adopting our new solutions for various reasons, including reluctance to disrupt existing relationships and business practices or to invest in necessary technological integration. Clients, vendors, and competitors may also react negatively to the announcement of new products and offerings, which may have a harmful effect on our relationships and our business.
Our technology must scale to process the increased ad requests on our platform. For each ad request that we process we incur infrastructure costs regardless of whether that ad request is ultimately monetized through our platform. The number of ad requests that we process has grown significantly in order to support additional ad spend on our platform, in particular with respect to CTV sellers who operate at large scale and experience spikes in viewership.
We must continue to increase the capacity of our platform to support the growth of our business and an increasing variety of advertising formats and platforms. Additionally, we must maintain a stable service infrastructure and reliable service delivery. To the extent we are unable, for cost or other reasons, to effectively increase the capacity of our platform, continue to process transactions at fast enough speeds, and support emerging advertising formats or services preferred by buyers, our revenue will suffer. Furthermore, failure to optimize and manage infrastructure costs efficiently could result in margin compression and increased financial strain.
We expect to continue to invest in our platform to meet increasing volume, including investments in on-prem data centers to support a higher percentage of our transactions. Such investment may negatively affect our profitability and results of operations. Additionally, any unexpected surges in traffic, inefficiencies in scaling, or disruptions to our infrastructure could degrade platform performance, harm our reputation, and cause us to lose business to competitors with more resilient or cost-effective solutions.
While header-bidding technologies have not been largely adopted by CTV sellers, such solutions or similar solutions geared towards increasing demand competition may become more prevalent in the future. If we are not able to effectively offer or adapt our technology to such solutions, it may lead to increased competition for CTV inventory, resulting in reduced opportunities or higher costs to monetize such inventory. We have addressed the market need for such requirements in part, through our ad server, SpringServe, which offers a unified programmatic demand solution for CTV, which leverages our existing programmatic SSP capabilities and connects with third party programmatic demand sources. However, this offering may not be adopted by clients, or such clients may adopt competing solutions. While still relatively nascent, as the programmatic market for CTV advertising continues to mature, other ad serving or similar technology platforms are likely to enter the market and/or gain market share, creating additional competitive pressure and attendant risks.
Our technology must scale to process the increased ad requests on our platform. Additionally, for each individual advertising impression created when a user visits a website or uses an application where our auctions technology is integrated, our technology must send bid requests to appropriate buyers, receive and process their responses, select a winner, and, increasingly, integrate with downstream decisioning systems. It must perform these transactions end-to-end within milliseconds.
We must continue to increase the capacity of our platform to support our high-volume strategy, to cope with increased data volumes and parties resulting from header bidding and an increasing variety of advertising formats and platforms. Additionally, we must maintain a stable service infrastructure and reliable service delivery. To the extent we are unable, for cost or other reasons, to effectively increase the capacity of our platform, continue to process transactions at fast enough speeds, and support emerging advertising formats or services preferred by buyers, our revenue will suffer. Furthermore, failure to optimize and manage infrastructure costs efficiently could result in margin compression and increased financial strain.
We expect to continue to invest in our platform to meet increasing demand, which may require significant expenditures on data processing capabilities, infrastructure, security enhancements, and compliance measures. Such investment may negatively affect our profitability and results of operations. Additionally, any unexpected surges in traffic, inefficiencies in scaling, or disruptions to our infrastructure could degrade platform performance, harm our reputation, and cause us to lose business to competitors with more resilient or cost-effective solutions.
We expect mobile applications to be the largest driver of our mobile business. Many mobile apps utilize software development kits, or SDKs, and other proprietary technology of third parties, such as aggregators, and it is those third parties, not the application providers themselves, that contract with us to provide exchange services to help monetize the inventory. Due to this consolidation, if our relationships with these third parties decline or are terminated, it may result in a larger than usual loss of access to mobile inventory. Moreover, while we have introduced our own mobile in-app SDK, we cannot be sure that our development efforts will be successful or that our solution will assist us in accessing mobile inventory. Any rapid and/or significant decline in the availability of mobile inventory can adversely affect our mobile advertising spend and growth prospects.
These fee concessions may be more prevalent among CTV publishers where inventory is scarce and concentrated among large sellers with significant negotiating leverage. Moreover, the majority of CTV transactions are currently executed through reserve auctions and we expect reserve auctions to grow as a percentage of revenue in mobile and desktop as well.auctions. Reserve auctions generally involve lower fees than we can charge for auction transactions and we may experience additional fee pressure as more competitors, including new entrants as well as sellers themselves, build their own technology and infrastructure to enable reserve auctions.
Our revenue, take rate (our fee as a percentage of advertising spend), the value of our business,revenue and the price of our stockprofitability could be adversely affected if we cannot maintain and grow our revenue and profitability through volume increases that compensate for price reductions, or if we are forced to make significant fee concessions, rebates, or refunds, or if buyers reduce spending with us or sellers reduce inventory available through our exchange due to fee disputes or pricing issues.
As a result of these factors, even if we are able to accurately forecast the anticipated total advertising spend transacted by buyers across our platform, we may have limited visibility regarding the revenue or Contribution ex-TAC (as defined in section "Key Operating and Financial Performance Metrics") we will generate. Any decrease in our take rate could cause our revenue and Contribution ex-TAC to decreasedecrease, notwithstanding an increase in the total spend transacted through our seller platform.
We reported net income of $144.6 million and $22.8 million during the years ended December 31, 2025 and December 31, 2024, respectively, and net loss of $159.2 million during the year ended December 31, 2024 and net loss of $159.2 million and $130.3 million during the years ended December 31, 2023, and 2022, respectively.2023. As of December 31, 2024,2025, we had an accumulated deficit of $661.2$516.6 million. We have implemented strategic plans designed to improve our financial performance and continue to increase revenue, and have taken steps to reduce unnecessary expenses and redirect spending to areas we expect to produce higher growth; however, these plans and steps may ultimately prove to be unsuccessful.

•changes in pricing of advertising inventory or pricing for our solution and our competitors' offerings, including potential further reductions in our pricing and overall take rate as a result of competitive pressure, changes in supply, improvements in technology and extension of automation to higher-value inventory,rate, uncertainty regarding rate of adoption, changes in the allocation of demand spend by buyers, changes in revenue mix, auction dynamics, pricing discussions or negotiations with clients and potential clients, header bidding and other factors;
•the effect of AI on our business;
•the ability of buyers to integrate demand directly with sellers without the use of our platform;
Generally, we invoice and collect from buyers the full purchase price for impressions they have purchased, retain our fees, and remit the balance to sellers. However, in some cases, we may be required or chooseelect to pay sellers for impressions delivered before we have collected, or even if we are unable to collect, from the buyer of those impressions. There can be no assurancesassurance that we will not experience bad debt in the future, and write-offs for bad debt could have a materially negative effect on our results of operations for the periods in which the write-offs occur. This is particularly true in the case of buyers that act as technological intermediaries, such as DSPs, since those DSPs control large amounts of spend across various advertisers and agencies. In addition to posing their own credit risk, such DSPs may not be required to pay us for specific inventory in the event the DSP is not able to collect payment from the underlying advertiser directing the campaign.
The digital advertising market may develop more slowly or differently than we expect, including as a response to advancements in AI, and if so, our business, growth prospects and financial condition would be adversely affected.
Advancements in artificial intelligence ("AI”) present both opportunities and risks to our business, particularly within the context of the open internet and display advertising. AI-driven platforms, especially those integrated with walled gardens or closed ecosystems, have the potential to alter the competitive dynamics of digital advertising by changing the way in which users access information and content on the open internet. This shift could reduce advertiser reliance on the open internet and create challenges for independent publishers, which in turn may negatively impact our business model. Furthermore, the rapid evolution of AI technologies could lead to diminishing demand for display advertising or reallocating budgets to new formats and approaches. If we are unable to address these disruptions, adapt to evolving market expectations, or compete effectively with AI-driven ecosystems, our growth and market position could be adversely impacted.
The more informed advertising is about its audience, the more valuable it is. Programmatic advertising enables more precise audience targeting based on the interests and actions of the user. Targeted advertising is generally more effective and valuable for buyers than other types of advertising, resulting in more revenue for sellers. In order to target advertising, we and our clients must collect and use data in a variety of ways. Our ability to collect, use, and disclose data about advertising purchase and sale transactions and user behavior and interaction with content is critical to the value of our services, and any limitation on our data practices could impair our ability to deliver effective solutions to our clients. Any restriction on the types of data we collect could make placement of advertising through our solution less valuable, with commensurate reductions in revenue.
Consumers can, with increasing ease, implement practices or technologies that limit our ability, or that of our sellers, buyers and business partners, to collect data. For example, users may delete or block the use of the cookies and similar technologies used to collect data, including through their browser or connected device settings. Consumers may also download "ad blocking" software that prevents certain cookies and other tracking technologies from being stored on a user’s computer or mobile device or from making calls to advertising partners, which may prevent the delivery of targeted or other advertisements. In addition, device manufacturers, browsers and other tools are increasingly promoting features that allow users to disable the collection of data. For example, Apple requires user opt-in before permitting access to Apple’s unique identifier, or IDFA. These shifts have had, and will likely continue to have, a substantial impact on the mobile advertising ecosystem and could harm growth in this channel.
In addition, device manufacturers, browsers and other tools are increasingly promoting features that allow users to disable the collection of data. For example, Apple requires user opt-in before permitting access to Apple’s unique identifier, or IDFA. Further, it is likely that Google will eventually deprecate the mobile advertising identifier used on Android devices. These shifts have had, and will likely continue to have, a substantial impact on the mobile advertising ecosystem and could harm growth in this channel.
Laws governing the processing of personal data also continue to impact our ability to collect data. For example, Directive 2002/58/EC (as amended by Directive 2009/136/EC), commonly referred to as the ePrivacy Directive, directs EU member states to ensure that accessing personal data on an Internetinternet user’s computer, such as through cookies and similar technologies, generally requires opt in consent and is allowed only if the user has been informed about such access and given his or her opt-in consent. Further, numerous comprehensive state privacy laws across the U.S. require businesses that engage in certain advertising uses of personal data to offer and honor an opt-out of such activities, including, in some states, through browser or device-based opt-out signals, such as the Global Privacy Control (“GPC”). Similar regulations have been proposed in the EU. Use of GPC and similar user privacy features provided on other channels of programmatic advertising, such as CTV, are growing. Technical or policy changes, including regulation or industry self-regulation, could also harm our growth in those channels. As further described in the risk factors below, current and potential future privacy laws and regulations in the U.S. and abroad already restrict, and could further restrict, the ability to collect and process certain types of user data.
Industry participants in the advertising technology ecosystem have long anticipated the deprecation of third-party cookies and other identifiers, making it more difficult to rely on such technologies to identify users' devices.
Industry participants in the advertising technology ecosystem have long anticipated the deprecation of third-party cookies and other identifiers, making it more difficult to rely on such technologies to identify users' devices. For several years, Google had announced plans to fully eliminate support for third-party cookies in the Chrome browser. However, as of the end of 2024, Google has decided to continue supporting third-party cookies for the foreseeable future, citing the need for additional time to refine alternative solutions. While this decision provides temporary continuity in the digital advertising ecosystem, it also perpetuates ongoing uncertainty for the long-term evolution of audience targeting and measurement practices.
Despite the continuation of cookies, advertisers,Advertisers, publishers, and technology platforms are increasingly prioritizing privacy-focused solutions, and a number of industry participants have suggested alternative identity solutions. Efforts like Google’s Privacy Sandbox, which aims to provide alternative tools for audience targeting without relying on third-party cookies, continue to be developed and tested. These tools, while intended to balance privacy and utility, may not fully replicate the capabilities of cookies and could disrupt established advertising workflows. Moreover, alternative identification solutions may require substantial development and commercial changes for us to support. There is also a risk that such tools will favor proprietary ad tech ecosystems, including Google’s,ecosystems potentially disadvantaging independent platforms like Magnite.
Even though third-party cookies remain supported, the programmatic ecosystem is increasingly shifting toward privacy-centric approaches that prioritize first-party data. We believe that this trend has the potential to shift the programmatic ecosystem from an identity model powered by buyers that are able to aggregate and target audiences through cookies and other tracking technologies to one enabled by sellers that have direct relationships with consumers and are therefore better positioned to obtain user data and consent for implementing first party identifiers. Google's shift away from eliminating third party cookies today may simply slow down this shift. While we believe that our platform and scale position us well to provide the infrastructure and tools needed for a publisher-centric identity model to succeed, there is no guarantee that our efforts will lead to an increase of the use of first-party publisher segments in the ecosystem. It is also possible that the increased use of first-party publisher segments will disproportionately benefit sellers or the large walled gardens that have access to large amounts of first party data. Additionally, these changes could create some variability in our revenue across certain buyers or sellers, depending on the timing of changes and developed solutions, and even if there is an increase in the proliferation of first-party publisher segments, we may still incur substantial re-engineering costs to optimize our solution for use with such segments.
These state laws require all businesses that engage in certain advertising uses of consumer personal data to offer and honor an opt-out of such activities, including, in some states, through universal browser or device-based preference signals such as GPC. Some state laws may also restrict use of sensitive information, including precise location information, for advertising purposes. The implementation of these state laws and any corresponding regulations will cause us to incur additional compliance costs and may impose additional restrictions on us and on our industry partners.
Separate from these comprehensive state consumer privacy laws, lawmakers continue to focus their efforts on data collection, processing, and disclosures by companies that do not have direct relationships with the consumers whose personal data they process. Several states, including California, Oregon, and Texas, have recently enacted or updated laws restricting the activities of "data brokers." Notably, California's Delete Act, dramatically increases obligations and potential penalties relative to the state’s preexisting data broker statute. Beyond additional transparency requirements, beginning in August 2026, companies registered as data brokers in California (including Magnite), must honor universal deletion requests consumers make of all data brokers via a deletion mechanism the statestate's willDelete create.Request and Opt-out Platform mechanism. These obligations may reduce the data available to Magnite, require us to develop complex and expensive compliance tools and procedures, and may result in reductions in revenue.
Moreover, we have from time-to-time become subject to putative class actions or other litigation, including claims based on developing or unsettled interpretations of privacy, data use, or consumer protection laws, which regardless of their ultimate merit may require significant resources to address, divert management attention, and result in reputational harm or adverse outcomes.
In 2018, IAB Europe released a tool, the Transparency and Consent Framework (the "TCF"), in order to assist sellers, advertisers and advertising technology providers, with passing signals related to the legal basis obtained for processing personal data. For example, the TCF is used to indicate in the bidstream when there is consent from end users in accordance with the ePrivacy Directive and GDPR. Following a decision by the Belgian Data Protection Authority ("ADP"), the TCF was revised in 2023. While the TCF is actively in use, its viability as a compliance mechanism remains under review by European authorities and we cannot predict its effectiveness over the long term.
We are subject to regulation with respect to political advertising activities, which are governed by various federal and state laws in the U.S., and national and provincial laws worldwide.worldwide, including the new Transparency and Targeting of Political Advertising in the EU, imposing strict prohibitions on the use of personal data for political advertising. Online political advertising laws are rapidly evolving and in certain jurisdictions we have compliance requirements with respect to political ads delivered on our platform. In some jurisdictions we may determine not to serve political advertisements due to uncertainty around these requirements and potential burdens of compliance. In addition, our sellers may impose restrictions on receiving political advertising. The lack of uniformity and increasing compliance requirements around political advertising may adversely impact the amount of political advertising spent through our platform, increase our operating and compliance costs, and subject us to potential liability from regulatory agencies.
Our business is subject to evolving corporate governance and public disclosure regulations and expectations, including with respect to environmental, social and governancesustainability matters that could expose us to numerous risks.

Over the past several years, we have made a number of investments to build what we believe is the leading independent programmatic CTV platform, including our 2021 acquisitions of SpotX, a leading CTV supply side platform, and SpringServe, a leading ad server for CTV. We believe these transactions are highly strategic, as the combination of our SSP and ad server allows us to offer publishers an independent full-stack solution that works across their entire video advertising business, for both programmatic and directly sold inventory, to manage yield and drive value. As a result of our investments, CTV has become the biggest growth driver of our business, with revenue growing 13%9% and Contribution ex-TAC growing 19%17% year over yearyear-over-year from 20232024 to 2024.2025.
We believe that we are well positioned to take advantage of a number of favorable market trends in CTV. In particular, as the pace of consumer adoption has accelerated and the streaming market has proliferated, the largest streaming publishers have adopted ad-supported models leading to a significant increase in the amount of CTV inventory available for advertisers.
As the industry matures, we anticipate that market dynamics will lead CTV sellers to make a greater percentage of inventory available through biddable auction environments with multiple buyers rather than programmatic guaranteed, in order to attractaccommodate a broader set of advertisers that have not historically advertised on linear TV. We believe that this shift, if it were to occur, would likely be beneficial to our CTV growth as biddable transactions tend to require a higher level of service and therefore carry a higher take-rate compared to reserve auctions. At the same time, we expect CTV advertisers that have historically transacted on our platform through managed service insertion orders to continue to shift budgets towards more automated solutions, which tend to carry a lower take rate; and as a result, we expect transactions through managed service insertion orders to become a smaller component of our overall business.
We have made and plan to continue to make significant investments in technology, sales and support related to our CTV growth initiatives, and believe CTV will be a significant driver of our revenue growth for the foreseeable future. In April 2025, we announced the introduction of our next generation SpringServe CTV platform. The new SpringServe platform combines the features and functionalities of our streaming SSP and ad server to provide a more efficient connection for buyers to premium CTV supply, while offering powerful tools and streamlined workflow for sellers through a single user interface.
In addition to CTV, we track mobile and desktop channels. We expect our revenue and Contribution ex-TAC from each of these channels to grow at a slower rate compared to CTV, with mobile expected to grow at a higher rate than desktop. AsIn such,particular, we believe growth rates for open web display will be lower across both mobile and desktop, consistent with the overall decline in search referral traffic. We expect our desktop and mobile web business to continue to decline as an overall percentage of our revenue in future periods; however, we expect that itcontributions from these channels will continue to represent a significant percentage of our revenue in the near term. Therefore, the mix of our desktop and mobile web business will continue to have a negative effect on our overall growth rate.
Our mobile channel consists of mobile web and mobile applications, with mobile applications expected to be a larger driver of our growth in future periods. A significant portion of the mobile application inventory on our platform is made available through third-party mobile technology platforms or aggregators, rather than application developers themselves. Accordingly, we are focused on expanding our relationships with these third parties in order to increase our access to inventory. Other important growth initiatives for our mobile and desktop channels include: bringing additional advertising demand to sellers through SPO and other buyer initiatives; increasing the operational efficiency of our platform to reduce costs for us as well as the process costs for buyers; developing alternative identity solutions to increase the value of seller inventory, as the industry shifts away from third-party cookies; and leveraging our machine learning and big data set to improve traffic shaping and generate higher-quality matching between buyers and sellers.sellers; and increasing adoption of our proprietary SDK for mobile in-app advertising.
Our results for the year-ended December 31, 2024, were negatively impacted by challenges in the fourth quarter in our desktop and mobile channels, where we experienced a significant drop in advertising demand following the election and through year-end. We believe this drop was temporary in nature and was likely due to fears of macro and political uncertainty due to the election.
We anticipate that our operating expenses will continue to increase in absolute dollars for the foreseeable future as we invest in technology and development to enhance our product features, in particular CTV, as well as sales and marketing to acquire new clients and reinforce our relationships with existing clients. At the same time, we are making additional investments in on-prem data centers to support a higher percentage of CTV transactions, with the goal of increasing the operational efficiency of our platform in order to realize long-term cost savings.
Regulatory Developments and Google Litigation
On April 17, 2025, the United States District Court for the Eastern District of Virginia (the "Court") ruled that Google LLC ("Google") had violated federal antitrust laws by willfully acquiring and maintaining monopoly power in the display publisher ad server market and display ad exchange (also called an SSP) market, and had unlawfully tied its display ad server and ad exchange. Having found Google liable, the Court held closing arguments in November 2025 to determine what remedies are appropriate to restore competition to the affected markets. While the specific timing and nature of these remedies remains uncertain, and Google has indicated its intent to appeal the decision, we expect this ruling to have a significant positive impact on our industry and business prospects.
Our mobile and desktop SSP competes directly with Google's ad exchange for the placement of display ads within the Google display ad server, which is estimated to be used by approximately 90% of open-web publishers. We believe that the conduct found to be unlawful by the Court provided Google's ad exchange with an unfair advantage relative to rival exchanges, such as our SSP, and artificially depressed our ability to win impressions within the Google display ad server. Moreover, we believe that Google's illegal conduct foreclosed the ability of publishers to freely choose what SSPs or exchanges they worked with to monetize inventory. As such, any remedy that creates a more level playing field and increases publisher choice is likely to improve our ability to monetize a greater share of display inventory while growing our market share in open-web display.
On September 16, 2025, in light of the Court's decision, we filed a lawsuit against Google in the U.S. District Court of the Eastern District of Virginia, seeking damages and other remedies (the "Google Action"). Our complaint alleges that Google engaged in anticompetitive conduct in the ad exchange and ad server markets in violation of federal antitrust laws, including actions that restrict publishers' ability to use competing services and favor Google's own advertising exchange, which caused us substantial harm and lost opportunity. Refer to "Our litigation with Google LLC presents potential risks that could adversely affect our business, results of operations and financial condition" in Item 1A. "Risk Factors".
Macroeconomic challenges, such as inflation, tariffs and trade wars, the interest rate environment, global conflicts, the risk of a recession, and labor strikes, generally have a negative impact on ad budgets, which in turn may lead to slower ad spend growth through our platform. Any worsening of macroeconomic conditions in future periods would likely have a negative effect on our financial results, the magnitude of which is difficult to predict. In addition, continuedinflation inflationand tariffs could result in an increase in our cost base relative to our revenue.revenue and increased cost associated with our infrastructure investments. Moreover, in response to U.S. tariffs, foreign countries in which we operate may enact additional or new taxes that are applicable to our business.
We generate revenue from the use of our platform for the purchase and sale of digital advertising inventory. Generally, our revenue is based on a percentage of the ad spend that runs through our platform, although for certain clients, services, or transaction types, we may receive a fixed CPM for each impression sold, and for advertising campaigns that are transacted through insertion orders, we earn revenue based on the full amount of ad spend that runs through our platform. In addition, we may receive certain fixed monthly fees for the use of our platform or products. We recognize revenue upon the fulfillment of our contractual obligations in connection with a completed transaction, subject to satisfying all other revenue recognition criteria. For the majority of transactions executed through our platform, we act as an agent on behalf of the publisher that is monetizing its inventory, and revenue is recognized net of any advertising inventory costs that we remit to sellers. With respect to certain revenue streams for managed advertising campaigns that are transacted through insertion orders, we report revenue on a gross basis, based primarily on our determination that the Company acts as the primary obligor in the delivery of advertising campaigns for our buyer clients with respect to such transactions.
For the years ended December 31, 2025, 2024, 2023, and 2022,2023, our revenue reported on a gross basis was 10%, 14%, 18%, and 18% of total revenue for the respective periods. AnyThe mix shift that causes an increasedecline in theour relativerevenue reported on a gross basis as a percentage of our revenue is primarily due to declines in our managed service business, which is accounted for on a gross basis would result in a higher revenue contribution and an associated decrease in our gross margin percentage (with no underlying impact on gross profit or Contribution ex-TAC,basis, as definedadvertisers incontinue sectionto "Keyshift Operatingbudgets and Financial Performance Metrics").

Our revenue recognition policies are discussed in more detail in Note 2 of the "Notes to the Consolidated Financial Statements."
Sales and Marketing. Our sales and marketing expenses primarily consistsconsist of personnel costs, including salaries, bonuses, and stock-based compensation, as well as marketing expenses such as brand marketing, travel expenses, trade shows and marketing materials, amortization expense associated with client relationships, and non-compete agreements from our business acquisitions, professional services, facilities-related costs, and depreciation expense. Our sales and support organization focuses on increasing the adoption of our solution by existing and new buyers and sellers and supports ongoing client relationships. We amortize acquired intangibles associated with client relationships from our business acquisitions over their estimated useful lives.
Technology and Development. Our technology and development expenses primarily consistsconsist of personnel costs, including salaries, bonuses, and stock-based compensation, as well as professional services associated with the ongoing development and maintenance of our solution, software costs, facilities-related costs, and depreciation and amortization expense. These expenses include costs incurred in the development, implementation, and maintenance of internal use software, including platform and related infrastructure. Technology and development costs are expensed as incurred, except to the extent that such costs are associated with internal use software development that qualifies for capitalization, which are then recorded as internal use software development costs, net, on our consolidated balance sheets. We amortize internal use software development costs that relate to our revenue-producing activities on our platform to cost of revenue and amortize other internal use software development costs to technology and development costs or general and administrative expenses, depending on the nature of the related project. We amortize acquired intangibles associated with technology and development functions from our business acquisitions over their estimated useful lives.
General and Administrative. Our general and administrative expenses primarily consistsconsist of personnel costs, including salaries, bonuses, and stock-based compensation, associated with our executive, finance, legal, human resources, compliance, and other administrative personnel, as well as accounting and legal professional services fees, facilities-related costs, depreciation expense, bad debt expense, and other corporate-related expenses.
Merger, Acquisition, and Restructuring Costs. Our merger, acquisition, and restructuring costs primarily consistsconsist of professional service fees associated with merger and acquisition activities, cash-based employee termination costs, related stock-based compensation charges, and other restructuring activities, including facility closures, relocation costs, contract termination costs, and impairment costs of abandoned technology associated with restructuring activities.
Foreign Currency Exchange (Gain) Loss, Net. Foreign currency exchange (gain) loss, net consists of gains and losses on foreign currency transactions and remeasurement of monetary assets and liabilities on our balance sheet denominated in foreign currencies. Foreign currency monetary assets and liabilities primarily consists of cash and cash equivalents, accounts receivable, accounts payable, and various intercompany balances held between our subsidiaries. Our primary foreign currency exposures are currencies other than the U.S. Dollar, principally the Australian Dollar, British Pound, Canadian Dollar, Euro, Japanese Yen, and New Zealand Dollar.
During the year ended December 31, 2025, we recorded an income tax benefit primarily driven by the release of our U.S. federal valuation allowances, the majority of our state valuation allowances, and certain foreign valuation allowances on deferred tax assets. The release was supported by sustained profitability and our cumulative three-year pre-tax income position, together with forecasts of future taxable income. As a result of this release, our effective tax rate for 2025 differs significantly from prior periods. A material valuation allowance release is not expected to recur in future periods.
Revenue increased $45.8 million, or 7%, for the year ended December 31, 2025 compared to the prior year. Our revenue growth was driven primarily by growth in CTV and mobile. Revenue from CTV, mobile, and desktop increased by $28.7 million, or 9%, $16.1 million, or 7%, and $1.0 million, or 1%, respectively.
Our CTV revenue growth for the year ended December 31, 2025 compared to the respective prior year period was negatively impacted by a decline in the relative percentage of transactions reported on a gross basis, compared to on a net basis. Transactions reported on a gross basis generally result in a higher revenue contribution with an associated increase in our traffic acquisition costs. See "Key Operating and Financial Performance Metrics" below for a discussion of Contribution ex-TAC, which presents a year-over-year comparison of our CTV growth, without considering the impact of traffic acquisition costs related to revenue reported on a gross basis.
Revenue increased $42.6 million, or 7%, for the year ended December 31, 2023 compared to the prior year. Our revenue growth was driven primarily by growth in mobile and CTV, which was partially offset by a decrease in desktop. Revenue from mobile and CTV increased by $39.7 million, or 21%, and $13.6 million, or 5%, respectively, while desktop decreased by $10.6 million, or 9%. During 2023, our growth rate in CTV was negatively impacted, in part, by a mix shift towards large CTV sellers that transacted primarily through reserve auctions, which carry a lower overall take rate compared to other transaction types.
Cost of revenue increased $7.8 million, or 3%, for the year ended December 31, 2025 compared to the prior year, primarily due to increases of $11.5 million in cloud hosting, data center, and bandwidth expenses, $9.1 million in software costs, and $4.0 million in personnel costs. These increases were partially offset by decreases of $16.9 million in traffic acquisition costs due to a decrease in revenue reported on a gross basis.
Cost of revenue increased $102.7 million, or 33%, for the year ended December 31, 2023 compared to the prior year, primarily due to increases of $69.3 million in depreciation and amortization. These increases were primarily driven by incremental amortization due to the acceleration of the remaining lives of certain acquired intangible assets and capitalized software from the integration of our legacy Magnite CTV and SpotX CTV platforms, which started in the fourth quarter of 2022 and was completed in the third quarter of 2023. The year over year increase in amortization due to the acceleration was $64.0 million. Cost of revenue also included increases of $26.2 million in cloud hosting, data center, and bandwidth expenses and $8.1 million in traffic acquisition costs, both primarily due to revenue growth and an associated increase in the volume of transactions processed on our platform.
Cost of revenue may fluctuate from quarter to quarter and period to period, on an absolute dollar basis and as a percentage of revenue, depending on revenue levels and the volume of transactions we process supporting those revenues, whether transactions are reported on a gross or net basis, and the timing and amounts of depreciation and amortization of equipment and software.
Sales and marketing expenses decreasedincreased $7.8$5.5 million, or 5%,3%, for the year ended December 31, 20242025 compared to the prior year, primarily due to increases of $10.2 million in personnel costs. These increases were partially offset by decreases of $17.4$6.6 million in depreciation and amortization, which were primarily driven by certain acquired intangible assets becoming fully amortized in 2023. These decreases were partially offset by increases of $9.5 million in personnel costs.2025.
Sales and marketing expenses decreased $26.1$7.8 million, or 13%,5%, for the year ended December 31, 20232024 compared to the prior year, primarily due to decreases of $44.3$17.4 million in depreciation and amortization, which were primarily driven by certain acquired intangible assets becoming fully amortized in 2022 and 2023. These decreases were partially offset by increases of $15.3$9.5 million of personnel costs.
Technology and development expenses decreased $10.5 million, or 11%, for the year ended December 31, 2025 compared to the prior year, primarily due to decreases of $4.6 million in personnel costs and $4.1 million in software costs.
Technology and development expenses increased $0.6 million, or 1%, for the year ended December 31, 2023 compared to the prior year.
General and administrative expenses increaseddecreased $7.8$3.7 million, or 9%,4%, for the year ended December 31, 20242025 compared to the prior year, primarily due to increasesdecreases of $5.9$4.0 million in personnelinsurance costs,and $4.1business taxes and $3.1 million in refinancing expenses associated with refinancing our 2021 Credit Agreement (defined below) in February 2024 and repricing our 2024 Term Loan B Facility (defined below) in September 2024, and $3.7 million in insurance and business taxes.. These increasesdecreases were partially offset by decreasesincreases of $4.1$2.0 million in bad debt expense and $2.7 million in facilities-relatedpersonnel costs. The higher bad debt expense in 2023 as compared to 2024 was primarily due to a buyer defaulting on payment obligations and filing for bankruptcy, resulting in bad debt expense of $4.2 million.

We incurred $0.2 million of merger, acquisition, and restructuring costs for the year ended December 31, 2025 and did not incur any merger, acquisition, and restructuring costs for the year ended December 31, 2024.
We did not incur any merger, acquisition, and restructuring costs for the year ended December 31, 2024. We incurred merger, acquisition, and restructuring costs of $7.5 million and $7.5 million during the years ended December 31, 2023 and 2022, respectively, primarily related to the acquisitions of SpotX, Inc. and SpringServe, LLC, which were completed on April 30, 2021 and July 1, 2021, respectively.
InFor the year ended December 31, 2023, thesewe incurred $7.5 million of merger, acquisition, and restructuring costs primarilyconsisting includedof $3.4 million of severance related expenses, $2.2 million of facilities related loss contracts, and $1.4 million of exit costs,costs all due to restructuring activities as a result of consolidating our legacy CTV and SpotX CTV platforms following the SpotXSpotX, acquisition.Inc. acquisition in 2021.
In 2022, these costs primarily included $3.3 million of impairment costs associated with abandoned technology, $2.0 million non-cash stock-based compensation expense associated with the acceleration of unvested equity awards, and $1.2 million of one-time cash-based employee termination costs due to restructuring activities related to the integration of our acquisitions.
Interest expense, net decreased by $5.3$8.1 million during the year ended December 31, 20242025 compared to the prior year.

The loss on extinguishment of debt of $2.2 million for the year ended December 31, 2025 was due to the March 2025 repricing of our 2024 Term Loan B Facility (defined below) and the loss on extinguishment of debt of $7.7 million for the year ended December 31, 2024 was due to the refinancing of our 2021 Credit Agreement (defined below) in February 2024 and the repricing of our 2024 Term Loan B Facility (defined below) in September 2024,2024. whichOur refinancing and repricing activities are further discussed below. The gain on extinguishment of debt of $26.5 million for the year ended December 31, 2023 was due to the repurchase of portions of our Convertible Senior Notes (defined below).
Other income decreased by $4.0 million for year ended December 31, 2025 compared to the prior year primarily due to decreases in rental income from real estate leases for which we sublease to other tenants. Other income was relatively flat for the year ended December 31, 2024 compared to the prior year as we had similar levels of sublease activity in each of the respective periods.
We recorded an income tax benefit of $74.0 million for the year ended December 31, 2025 compared to an income tax expense of $3.7 million for the year ended December 31, 2024 compared to an income tax expense ofand $1.6 million and an income tax benefit $5.3 million for the years ended December 31, 20232024 and 2022,2023, respectively. The income tax expensebenefit for the year ended December 31, 20242025 was primarily driven by the resultrelease of our abilityU.S. tofederal recognizevaluation DTAs subject toallowances, the domesticmajority of our state valuation allowanceallowances, and thecertain stateof andour foreign income tax provisions. We continue to maintain a valuation allowanceallowances for our domesticon deferred tax assets. The release was supported by sustained profitability and our cumulative three-year pre-tax income position, together with forecasts of future taxable income. As a result of the valuation allowance release, our effective tax rate for 2025 differs significantly from prior periods. A material valuation allowance release is not expected to recur in future periods.
On July 4, 2025, the President of the United States signed H.R. 1, commonly referred to as the "One Big Beautiful Bill Act" into law. These changes were reflected in the income tax provision for the year ended December 31, 2025. We have evaluated the tax law as it relates to our financials and determined there is no material impact on the period presented above. Based on current projections, the continuing impact will be a deferral of the payment of current income taxes over multiple years; however, we expect the net impact to our effective tax rate for 2026 to be immaterial. We will continue to monitor for any impact of future guidance.
The income tax expense for the year ended December 31, 2024 was primarily the result of the domestic valuation allowance and the federal, state, and foreign income tax liabilities.
The income tax benefit for the year ended December 31, 2022 was primarily the result of recognizing the benefit of deferred tax assets previously subject to the domestic valuation allowance and the foreign income tax liability. The net deferred tax liabilities recorded in connection with prior acquisitions and current taxable income for the year provided sources of taxable income to support the realization of pre-existing deferred tax assets.
In addition to our GAAP results, we review non-GAAP financial measures, including Contribution ex-TAC and Adjusted EBITDA, to help us evaluate our business on a consistent basis, measure our performance, identify trends affecting our business, establish budgets, measure the effectiveness of investments in our technology and development and sales and marketing, and assess our operational efficiencies. Our non-GAAP financial measures are discussed below. RevenueRevenue, cost of revenue, and net income (loss) are discussed above under the headings "Components of Our Results of Operations" and "Results of Operations."
Contribution ex-TAC increased $57.8$62.7 million, or 11%,10%, for the year ended December 31, 20242025 compared to the year ended December 31, 2023. The increase in Contribution ex-TAC was primarily due to the growth drivers described above for revenue.2024.
Contribution ex-TAC increased $34.5$57.8 million, or 7%,11%, for the year ended December 31, 20232024 compared to the year ended December 31, 2022. The increase in Contribution ex-TAC was primarily due to the growth drivers described above for revenue.2023.
We define Adjusted EBITDA as net income (loss) adjusted to exclude stock-based compensation expense, depreciation and amortization, including amortization of acquired intangible assets, impairment charges, interest income or expense, provision (benefit) for income taxes, and othercertain cash and non-cash based income or expenses that we do not consider indicative of our core operating performance, including, but not limited to foreign exchange gains and losses, acquisition and related items, gains or losses on extinguishment of debt, other debt refinancing expenses, certain litigation expenses, and non-operational real estate and other expenses (income), net, and provision (benefit) for income taxes.net. We believe Adjusted EBITDA is useful to investors in evaluating our performance for the following reasons:
•Adjusted EBITDA does not reflect certain cash and non-cash charges related to acquisition and related items, such as amortization of acquired intangible assets, merger, acquisition, or restructuring related severance costs, certain transaction expenses, and changes in the fair value of contingent consideration.
•Adjusted EBITDA does not reflect cash and non-cash charges and changes in, or cash requirements for, acquisition and related items, such as certain transaction expenses.
•Adjusted EBITDA does not reflect cash and non-cash charges related to interest income and interest expense and certain financing transactions such as gains or losses on extinguishment of debt or other debt refinancing expenses.
•Adjusted EBITDA does not reflect litigation expenses for specific proceedings.
•Adjusted EBITDA does not reflect certain non-operational real estate and other (income) and expense, net, which consists of transactions or expenses that are typically by nature non-operating, one-time items, or unrelated to our core operations.net.
Adjusted EBITDA increased by $25.5 million during the year ended December 31, 2024 compared to the year ended December 31, 2023, primarily due to increases in revenue, described above, which were partially offset by increases in expenses to support this revenue growth.

CTV viewership is growing rapidly and the pace of adoption is accelerating the transition of linear television to CTV programming. Initially, many streaming services were subscription based, but as the market has matured, the largest streaming publishers have adopted ad-supported models or hybrid models that rely on a combination of subscription fees and advertising. With the proliferation of CTV advertising inventory, we believe that brand advertisers looking to engage with streaming viewers will continue to shift their budgets from linear to CTV. Moreover, we believe that as the amount of CTV inventory continues to scale, it will become increasingly more accessible to small and medium sized businesses, many of whom have no experience advertising on linear TV. We believe this transition is likely to be accelerated by advancements in AI, and in September 2025 we completed the acquisition of Streamrai, Inc. ("see in full comparisonStreamer.aiStreamr.ai"), a self-service platform thatspecializes in artificial intelligence tools that make CTV advertising accessible to small and medium-sized businesses. The Streamr.ai technologyleverages generative AI to automate the creation of broadcast-quality video ads and streamline campaign setup, allowing advertisers to launch CTV campaigns in significantly less time and at significantly less cost than traditional methods.

Artificial Intelligence
Advancements in AI present both opportunities and risks to our business. AI is changing the way in which users access information and content on the open internet, in particular with respect to search referral traffic, which has and is expected to continue to decline. This shift could reduce the volume of open web display inventory monetized through our platform. At the same time, AI has the potential to create new digital advertising opportunities through emerging formats such as advertising units that appear within outputs generated by AI models.
In addition, the emergence of AI-driven protocols and transition frameworks has the potential to simplify programmatic activation and execution, improve advertising outcomes, and increase the value of advertising inventory by surfacing valuable real-time insights. To capitalize on these opportunities, we have made significant investments building AI capabilities into our platform for both publishers and buyers. Our seller agent allows publishers to seamlessly create custom inventory and audience packages that are discoverable and purchasable by buyer agents, while our buyer agent enables buyers to create custom media plans from simple RFIs, generate ad creatives, and activate and discover audience opportunities. We also recently announced Magnite Orchestration, a coordination layer that connects agents within a shared environment, allowing buyers to connect their preferred agentic buying tools with Magnite seller agents.
We believe we are well positioned to benefit from SPO in the long run as a result of our transparency, our broad and unique inventory supply across all channels and formats, buyer tools, such as our ClearLine product offering and buyer marketplaces, traffic filtering technology that reduces the cost of working with us, and brand safety measures.
In addition, header bidding has led to a significant increase in the number of ad impressions to be processed and analyzed through our platform as well as by DSPs, which can lead to increased costs if not properly addressed. WeOur platform analyzes large repositories of data and utilizes machine learning to continuously work to increase the operational efficiency of our platform, so as to enable buyers and sellers to achieve their campaign and monetization objectives in a cost-effective manner.manner, including through the use of traffic optimization and bid filtering technology.
In CTV, solutions similar to header bidding that are geared towards increasing demand competition have largely been built directly within the ad server. For instance, our SpringServe CTV platform enables sellers to offer their inventory to multiple programmatic demand sources to compete in a unified auction.
Macroeconomic challenges such as inflation, tariffs and trade wars, the interest rate environment, global conflicts, the risk of a recession, labor strikes, and significant volatility in commodity prices, including the price of oil, generally have a negative impact on ad budgets, which in turn may lead to slower ad spend growth through our platform. Any worsening of macroeconomic conditions in future periods would likely have a negative effect on our financial results, the magnitude of which is difficult to predict. In addition, inflationinflation, supply chain disruptions and tariffs could result in an increase in our cost base relative to our revenuerevenue, and increased cost or difficulty procuring items associated with our infrastructure investments. Moreover, in response to U.S. tariffs, foreign countries in which we operate may enact additional or new taxes that are applicable to our business.
For the three and six months ended MarchJune 31,30, 20262026, our revenue reported on a gross basis was 3% and 3%, respectively, of total revenue and for the three and six months ended June 30, 2025, our revenue reported on a gross basis was 4%11% and 11%, respectively, of total revenue.11%. The decline in our revenue reported on a gross basis as a percentage of our revenue is primarily due to declines in our managed service business, which is accounted for on a gross basis, as advertisers continue to shift budgets towards more automated solutions.
Comparison of the Three and Six Months Ended MarchJune 31,30, 2026 and 2025
Revenue increased $8.6$19.5 million, or 6%,11%, for the three months ended MarchJune 31,30, 2026 compared to the prior year period. Our revenue growth was driven by growth in CTV,CTV and mobile, which increased by $12.8$17.7 million, or 18%.

Our CTV revenue growth for the threesix months ended MarchJune 31,30, 2026 compared to the prior year period was negatively impacted by a decline in the relative percentage of transactions reported on a gross basis, compared to on a net basis. Transactions reported on a gross basis generally result in a higher revenue contribution with an associated increase in our traffic acquisition costs. See "Key Operating and Financial Performance Metrics" below for a discussion of Contribution ex-TAC, which presents a year-over-year comparison of our CTV growth, without considering the impact of traffic acquisition costs related to revenue reported on a gross basis.
Cost of revenue expenses decreased $2.4$2.9 million, or 4%, for the three months ended MarchJune 31,30, 2026 compared to the prior year period, primarily due to a decrease of $6.5$8.1 million in traffic acquisition costs due to a decrease in revenue reported on a gross basis.basis, This decreasewhich was partially offset by increases of $2.6$3.1 million in cloud hosting, data center,depreciation and bandwidthamortization expenses, $1.2 million in software license expenses and $1.1$0.8 million in personnel costs.
Cost of revenue decreased $5.3 million, or 4%, for the six months ended June 30, 2026 compared to the prior year period, primarily due to a decrease of $14.6 million in traffic acquisition costs due to a decrease in revenue reported on a gross basis, which was partially offset by increases of $4.2 million in depreciation and amortization expenses, $2.8 million in technology fees and $1.9 million in personnel costs.
Sales and marketing expenses decreasedincreased $2.0$4.7 million, or 4%,11%, for the three months ended MarchJune 31,30, 2026 compared to the prior year period, primarily due to an increase of $4.9 million in personnel costs, which was partially offset by a decrease of $2.3$0.8 million in depreciation and amortization, which was driven by certain acquired intangible assets becoming fully amortized in 2025.
Sales and marketing expenses increased $2.7 million, or 3% for the six months ended June 30, 2026 compared to the prior year period, primarily due to an increase in of $5.1 million in personnel costs, which was partially offset by a decrease of $3.1 million in depreciation and amortization, which was driven by certain acquired intangible assets becoming fully amortized in 2025.
Technology and development expenses increased $2.9$2.6 million, or 13%,12%, for the three months ended MarchJune 31,30, 2026 compared to the prior year period, primarily due to increasesan increase of $1.7 million in event and travel-related expenses and $1.2$2.1 million in personnel costs.
Technology and development expenses increased $5.4 million, or 12%, for the six months ended June 30, 2026 compared to the prior year period, primarily due to increases of $3.3 million in personnel costs and $1.7 million in event and travel-related expenses.
General and administrative expenses increased $1.0$5.9 million, or 4%,26%, for the three months ended MarchJune 31,30, 2026 compared to the prior year period, primarily due to increases of $1.0$4.1 million in professional servicesfees, expenses.including legal costs, $0.8 million in personnel costs, $0.5 million in insurance and taxes related costs, and $0.4 million in software license fees.

Foreign exchange (gain) loss, net decreased by $2.4$5.2 million and $7.5 million for the three and six months ended MarchJune 31,30, 20262026, respectively, compared to the prior year periodperiods due to movements in foreign currency exchange rates and the amount of foreign currency-denominated cash, receivables, and payables, which were impacted by our billings to buyers, payments to sellers, and intercompany balances.
The loss on extinguishment of debt of $2.2 million forin the threesix months ended MarchJune 31,30, 2025, was due to the March 2025 repricing of our 2024 Term Loan B Facility (defined below).
Other income was relatively flat for the three and six months ended MarchJune 31,30, 2026 compared to the prior year periodperiods as we had similar levels of sublease activity.activity in both periods.
Provision (Benefit) for Income Taxes
We recorded an income tax benefitprovision of $0.7$6.2 million and $0.9$1.0 million for the three months ended MarchJune 31,30, 2026 and 2025, respectively, and $5.5 million and $0.1 million for the six months ended June 30, 2026 and 2025, respectively. The tax benefitprovision for the three and six months ended MarchJune 31,30, 2026 was primarily the result of thefederal, vestingstate ofand share-basedforeign awards.income tax provisions. The tax benefitprovision for the three and six months ended MarchJune 31,30, 2025 was primarily the result of the Company's ability to recognize deferred tax assets subject to the domestic valuation allowance and the federal, state, and foreign income tax provisions.
On July 4, 2025, the President of the United States signed H.R. 1, commonly referred to as the "One Big Beautiful Bill Act" into law. These changes were reflected in theOur income tax provision for the three and six months ended MarchJune 31,30, 2026.2026 reflects the impacts of the "One Big Beautiful Bill Act," which became effective on July 4, 2025. We have evaluated the tax law as it relates to our financials and determined there is no material impact on the periods presented above. Based on current projections, the continuing impact will be a deferral of the payment of current income taxes over multiple years; however, we expect the net impact to our effective tax rate for 2026 to be immaterial. We will continue to monitor for any impact of future guidance.
In addition to our GAAP results, we review non-GAAP financial measures, including Contribution ex-TAC and Adjusted EBITDA, to help us evaluate our business on a consistent basis, measure our performance, identify trends affecting our business, establish budgets, measure the effectiveness of investments in our technology and development and sales and marketing, and assess our operational efficiencies. Our non-GAAP financial measures are discussed below. Revenue, cost of revenue, and net income (loss) are discussed above under the headings "Components of Our Results of Operations" and "Results of Operations."
Our use of Contribution ex-TAC has limitations as an analytical tool and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under GAAP. A potential limitation of this non-GAAP financial measure is that other companies, including companies in our industry which have similar business arrangements, may define Contribution ex-TAC differently, which may make comparisons difficult. Because of these and other limitations, you should consider our non-GAAP measures only as supplemental to GAAP-based financial performance measures, including revenue, gross profit, net income (loss) and cash flows.
The following table presents the calculation of gross profit and reconciliation of gross profit to Contribution ex-TAC for the three and six months ended MarchJune 31,30, 2026 and 2025:
The following table presents Contribution ex-TAC by channel for the three and six months ended MarchJune 31,30, 2026 and 2025:
Contribution ex-TAC increased $15.1$27.6 million, or 10%,17%, for the three months ended MarchJune 31,30, 2026 compared to the prior year period. The increase in Contribution ex-TAC was primarily due to the growth in CTV revenue.
Contribution ex-TAC increased $42.7 million, or 14%, for the six months ended June 30, 2026 compared to the prior year period. The increase in Contribution ex-TAC was primarily due to the growth in CTV revenue.
We define Adjusted EBITDA as net income (loss) adjusted to exclude stock-based compensation expense, depreciation and amortization, including amortization of acquired intangible assets, impairment charges, interest income or expense, provision (benefit) for income taxes, and certain cash and non-cash based income or expenses that we do not consider indicative of our core operating performance, including, but not limited to foreign exchange gains and losses, acquisitionacquisition, severance costs and other related items, gains or losses on extinguishment of debt, other debt refinancing expenses, certain litigation expenses, and non-operational real estate and other expenses (income), net. We believe Adjusted EBITDA is useful to investors in evaluating our performance for the following reasons:
Our Adjusted EBITDA is influenced by fluctuations in our revenue, cost of revenue, and the timing and amounts of the cost of our operations. Adjusted EBITDA should not be considered as an alternative to net income (loss),income, income (loss) from operations, or any other measure of financial performance calculated and presented in accordance with GAAP.
The following table presents a reconciliation of net income (loss),income, the most comparable GAAP measure, to Adjusted EBITDA for the three and six months ended MarchJune 31,30, 2026 and 2025:
Adjusted EBITDA increased by $6.1$16.2 millionmillion, or 30%, during the three months ended MarchJune 31,30, 2026 compared to the prior year period and increased by $22.3 million, or 24%, during the six months ended June 30, 2026 compared to the prior year period.
