AgenticOS Adoption Drives Momentum

• Since launching in January 2026, PubMatic has launched more than 30 fully autonomous, end-to-end campaigns globally. Notably, every participating advertiser has returned to run additional agentic campaigns, reinforcing the strength of performance and operational efficiency.

• PubMatic and Abovo Maxlead launched one of the first Agentic AI advertising campaigns in the Netherlands, integrating Abovo's Mediavision AI with PubMatic's AgenticOS to optimize CTV. The campaign accelerated time to activation and shifted more spend to working media.

Top Global Commerce Media Partners Added

• Integrated with Walmart Connect Select as a preferred supply partner, delivering curated, high-performing CTV inventory to drives stronger engagement, higher conversion rates, and more efficient media spend to its buyers.

• Integrated Unity LevelPlay into PubMatic's OpenWrap SDK. PubMatic provides direct, transparent access to the three largest mobile mediation platforms, representing over 90% of SDK inventories.
• Integrated with AdRoll — the first DSP on PubMatic's platform to connect via Model Context Protocol — enabling AI agents on both the demand and supply side to communicate directly, diagnose and resolve issues within minutes.

New AI-Powered Solutions Drive Performance and Streamline Omnichannel Workflows

• Integrated Creative Engagement Suite into AgenticOS, giving advertisers like Horizon Media unified access to advanced formats like pause ads and shoppable units alongside agentic optimization across CTV, mobile, and premium inventory like Sling TV.

Diversified revenue mix and expanded reach on the buy side

• Strength in CTV was led by the Americas, where revenue grew 13% year over year, and represented approximately 80% of total CTV revenue. Excluding the legacy DSP buyer, global CTV revenue grew 18% year-over-year.
• Q1 2026 revenue from mobile app grew 25%+ year-over-year.
• Emerging revenues² in Q1 2026 grew 80%+ year over year and represented approximately 14% of total revenues in the quarter, which includes revenue from newly launched AI solutions.

• Cost of revenue per million impressions processed decreased 20% on a trailing twelve month period, as compared to the prior period.

Financial Outlook

Our outlook assumes that general market conditions do not significantly deteriorate as it relates to current macroeconomic and geopolitical conditions.

For the second quarter of 2026, we expect the following:

• Revenue to be in the range of $68 million to $70 million, inclusive of an impact from one of our top DSP buyers.
• Adjusted EBITDA to be in the range of $8.0 million to $10.0 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, May 7, 2026 at 1:30 p.m. Pacific Time (4:30 p.m. Eastern Time).

¹ Fully diluted shares include common shares outstanding as of March 31, 2026 plus dilutive securities related to employee stock awards under the treasury stock method, calculated as if the Company were in a net income position.

² Emerging revenue includes Activate, Commerce Media, Connect and AI Solutions.

Non-GAAP Financial Measures

In addition to our results determined in accordance with U.S. generally accepted accounting principles (GAAP), including, in particular operating loss, net cash provided by operating activities, and net 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 loss adjusted for stock-based compensation expense, depreciation and amortization, litigation related expenses, interest income, and benefit from income taxes. Adjusted EBITDA margin represents adjusted EBITDA calculated as a percentage of revenue. We define non-GAAP net income as net 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 loss and net loss, we use adjusted EBITDA and non-GAAP net loss 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 loss 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 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 loss 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 loss 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 loss along with other GAAP-based financial performance measures, including net income and our GAAP financial results.
