The section titled “Non-GAAP Financial Measures” below describes our usage of non-GAAP financial measures. Reconciliations between historical GAAP and non-GAAP information are contained at the end of this press release following the accompanying financial data.

“Our fourth-quarter results represented an important structural inflection point for PubMatic, as we meaningfully exceeded expectations on both revenue and adjusted EBITDA,” said Steve Pantelick, CFO at PubMatic. “Excluding political revenues and the legacy DSP referenced mid 2025, the underlying 83% of our business grew 18% year over year. For the quarter overall, we delivered 35% adjusted EBITDA margins and strong free cash flow. This performance reflects the scaling of our secular growth engines in CTV, mobile app, and emerging revenues, combined with disciplined cost management and AI-enabled automation that continue to drive operating leverage. Looking ahead, we expect to return to double-digit revenue growth in the second half of 2026, with corresponding margin expansion supported by revenue scale and AI-powered efficiencies.”

¹ Net dollar-based retention is calculated by starting with the revenue from publishers in the trailing twelve months ended December 31, 2024 (“Prior Period Revenue”). We then calculate the revenue from these same publishers in the trailing twelve months ended December 31, 2025 (“Current Period Revenue”). Current Period Revenue includes any upsells and is net of contraction or attrition, but excludes revenue from new publishers. Our net dollar-based retention rate equals the Current Period Revenue divided by Prior Period Revenue. 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.

² Omnichannel revenue includes CTV, video and mobile.
³ Emerging revenue includes Activate, Commerce Media, Connect and AI Solutions.

Financial Outlook

Our outlook assumes that general market conditions do not significantly deteriorate as it relates to current macroeconomic and geopolitical conditions.
Accordingly, we estimate the following:
For the first quarter of 2026, we expect the following:

• Revenue to be in the range of $58 million to $60 million, inclusive of an impact from one of our top DSP buyers.
• Adjusted EBITDA to be in the range of $(0.5) million to $1.0 million. Adjusted EBITDA expectation assumes a negative foreign currency exchange impact predominantly from Euro and Pound Sterling.

Although we provide guidance for adjusted EBITDA, we are not able to provide guidance for net income (loss), the most directly comparable GAAP measure. Certain elements of the composition of GAAP net income (loss), including stock-based compensation expenses, are not predictable, making it impractical for us to provide guidance on net income or to reconcile our adjusted EBITDA guidance to net income without unreasonable efforts. For the same reason, we are unable to address the probable significance of the unavailable information.

Conference Call and Webcast details

PubMatic will host a conference call to discuss its financial results on Thursday, February 26, 2026 at 1:30 p.m. Pacific Time (4:30 p.m. Eastern Time). A live webcast of the call can be accessed from PubMatic’s Investor Relations website at https://investors.pubmatic.com . An archived version of the webcast will be available from the same website after the call.

Non-GAAP Financial Measures

In addition to our results determined in accordance with U.S. generally accepted accounting principles (GAAP), including, in particular operating income (loss), net cash provided by operating activities, and net income (loss), we believe that adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, non-GAAP earnings per share and free cash flow, each a non-GAAP measure, are useful in evaluating our operating performance. We define adjusted EBITDA as net income (loss) adjusted for stock-based compensation expense, depreciation and amortization, litigation related expenses, interest income, and provision for (benefit from) income taxes. Adjusted EBITDA margin represents adjusted EBITDA calculated as a percentage of revenue. We define non-GAAP net income as net income (loss) adjusted for stock-based compensation expense, litigation related expenses, and adjustments for income taxes. We define non-GAAP free cash flow as net cash provided by operating activities reduced by purchases of property and equipment and capitalized software development costs.

In addition to operating income (loss) and net income (loss), we use adjusted EBITDA and non-GAAP net income as measures of operational efficiency. We believe that these non-GAAP financial measures are useful to investors for period to period comparisons of our business and in understanding and evaluating our operating results for the following reasons:

• Adjusted EBITDA and non-GAAP net income are widely used by investors and securities analysts to measure a company’s operating performance without regard to items such as stock-based compensation expense, depreciation and amortization, litigation related expenses, interest expense, and provision for (benefit from) income taxes that can vary substantially from company to company depending upon their financing, capital structures and the method by which assets were acquired; and,
• Our management uses adjusted EBITDA and non-GAAP net income in conjunction with GAAP financial measures for planning purposes, including the preparation of our annual operating budget, as a measure of operating performance and the effectiveness of our business strategies and in communications with our board of directors concerning our financial performance; and adjusted EBITDA provides consistency and comparability with our past financial performance, facilitates period-to-period comparisons of operations, and also facilitates comparisons with other peer companies, many of which use similar non-GAAP financial measures to supplement their GAAP results.

Our use of non-GAAP financial measures has limitations as an analytical tool, and you should not consider them in isolation or as a substitute for analysis of our financial results as reported under GAAP. Some of these limitations are as follows:

• Adjusted EBITDA does not reflect: (a) changes in, or cash requirements for, our working capital needs; (b) the potentially dilutive impact of stock-based compensation; or (c) tax payments that may represent a reduction in cash available to us;
• Although depreciation and amortization expense are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements; and
• Non-GAAP net income does not include: (a) the potentially dilutive impact of stock-based compensation; (b) non-ordinary course litigation related expenses; or (c) income tax effects for stock-based compensation

Because of these and other limitations, you should consider adjusted EBITDA and non-GAAP net income along with other GAAP-based financial performance measures, including net income and our GAAP financial results.
