Our technology platform empowers the world’s leading digital content creators (which we refer to as “publishers”) across the open internet to maximize monetization of their advertising inventory. Our platform also provides control and transparency to buyers, which includes advertisers, agencies, agency trading desks, and demand side platforms (“DSPs”), (which we collectively refer to as “buyers”) and enables both publishers and buyers to drive better business outcomes. Our infrastructure-driven approach allows for the efficient processing and utilization of data in real time. By delivering scalable and flexible programmatic innovation, we believe we improve outcomes for our customers while championing a vibrant and transparent digital advertising supply chain.
Current wording

Previous wording
We continue to focus on the strengths that we believe provide us with long-term competitive advantages. These strengths include our global, omnichannel reach which targets a diverse set of publishers touching many ad formats and digital device types, including mobile app, mobile web, desktop, display, video, over-the-top video/connected TV (“OTT/CTV”), and rich media. Additionally, as an independent infrastructure provider prioritizing transparency, we can be more closely aligned with both publishers and buyers which has enabled us to build direct relationships with publishers, advertisers, agencies, and DSPs and create bespoke products that meet our customers’ needs. We have also maintained a demonstrated track record of stability and agility to address these market conditions and provide superior outcomes for both publishers and buyers. Finally, we have designed our technology to efficiently process real-time advertising transactions while leveraging data to optimize outcomes for publishers and buyers. We own and operate our software and hardware infrastructure globally, which saves significant infrastructure expenditures as compared to public cloud alternatives.

The digital advertising ecosystem continues to evolve and adapt at a rapid pace. Some noted trends include the continued growth of digital media across multiple platforms, a continued increase in the number of ad impressions processed and analyzed in real-time by each participant in the digital advertising ecosystem, and a desire for transparency and control throughout the supply chain from both the buyers and publishers. Additionally, rapidly evolving data and privacy regulations and industry standards continue to impact our business. For example, in April 2025, Google confirmed that it was abandoning its effort to deprecate the use of third-party cookies in Chrome and instead ask users to opt-in or opt-out of cookies in Chrome, which may impact the industry’s anticipated shift to alternative identity solutions.

Additionally, recent macroeconomic uncertainty, including adopted or proposed changes in the trade policies and tariff rates of the United States and international trade partners, slowing domestic growth, economic recession concerns, interest rate fluctuations, volatility in domestic and international equity and debt markets, foreign currency fluctuation and weakening of the U.S. Dollar, and persistent inflation in the U.S. and other markets globally, continue to create economic volatility and dislocation in the capital and credit markets in the U.S. and globally. To date, we have not observed material impacts in our business or outlook, but we intend to continue to monitor macroeconomic conditions closely and may determine to take certain financial or operational actions in response to such conditions to the extent our business begins to be adversely impacted.
Current wording
Additionally, recent macroeconomic uncertainty, including impacts from the ongoing conflict in the Middle East and resulting disruption to international trade and energy markets, adopted or proposed changes in the trade policies and tariff rates of the United States and international trade partners, slowing domestic growth, economic recession concerns, interest rate fluctuations, volatility in domestic and international equity and debt markets, foreign currency fluctuation and weakening of the U.S. Dollar, and persistent inflation in the U.S. and other markets globally, continue to create economic volatility and dislocation in the capital and credit markets in the U.S. and globally. A prolonged disruption to global trade, whatever the source, could dampen advertiser budgets, increase operating costs, reduce consumer spending, and adversely affect economic conditions in the markets in which we operate, including North America, Europe, and Asia. Escalating geopolitical tensions and volatility, including in the Middle East, could compound these effects by disrupting energy markets, global supply chains, and general consumer and business confidence. To date, we have not observed material impacts in our business or outlook, but we intend to continue to monitor macroeconomic conditions closely and may determine to take certain financial or operational actions in response to such conditions to the extent our business begins to be adversely impacted.

Net dollar-based retention rate is an important indicator of publisher satisfaction and usage of our platform, as well as potential revenue for future periods. We calculate our net dollar-based retention rate at the end of each quarter for a cumulative twelve months.

We then calculate the revenue from these same publishers in the current trailing twelve-month period (“Current Period Revenue”). Current Period Revenue includes any upsells and is net of contraction or attrition, but excludes revenue from new publishers.

Further, we work with DSPs to help them reduce their costs and improve advertiser ROI, which in turn makes us the specialized cloud infrastructure platform of choice for many of our buying partners. We depend upon a limited number of large DSPs for a large percentage of impressions purchased and our business results, including revenues, may be impacted by changes in their pricing strategies, bidding algorithms or go-to market efforts. As buyers increasingly consolidate their spending with fewer larger technology platforms, we seek to bring an increased proportion of their digital ad spending to our platform through direct deals. Supply Path Optimization (“SPO”) continues to be a major growth driver for us as we add new SPO relationships and expand existing ones. We have been investing in SPO technology and partnerships for over five years and SPO represented over 55% of total activity for the three months ended September 30, 2025.

We focus on monetizing digital impressions by coordinating over a hundred billion real-time auctions and nearly a trillion bids globally on a daily basis, using our specialized cloud software, machine learning algorithms, and scaled transaction infrastructure. Valuable ad impressions are transparent and data rich, viewable by humans, and verifiable. Each ad impression we auction consists of 703 independent data parameters, which can yield valuable insights if recorded and analyzed properly. This processing of voluminous data for each ad impression must occur in less than half a second as consumers expect a seamless digital ad experience. We continually assess impressions from new and existing publishers through a rigorous validation process. We add or remove impressions from our platform based on an assessment of the projected value of the impressions, which is influenced by the type of publisher and its related consumers, as well as the potential volume of monetizable impressions and ad format types, such as digital video. We continuously create and iterate algorithms that leverage vast datasets flowing through our infrastructure to improve the liquidity in our marketplace. Our ability to drive successful outcomes in the real-time auction process on behalf of our publishers and buyers will affect our operating results.

Our future capital requirements and the adequacy of available funds will depend on many factors, including those set forth under “Risk Factors” in this report and in our Annual Report on Form 10-K for the year ended December 31, 2025. As of March 31, 2026, our material cash requirements included the contractual commitments set forth under “Contractual Obligations and Future Cash Requirements.”
