PubMatic (NASDAQ: PUBM) shares jumped more than 30% in pre-market trading on August 7, 2026, after the digital advertising technology company reported second-quarter results that substantially exceeded Wall Street expectations. Revenue reached $78.6 million, up 11% year-over-year, while adjusted earnings per share hit $0.12 and adjusted EBITDA rose 38% to $19.6 million with a 25% margin. The results marked an earlier-than-expected return to double-digit growth, stronger profitability, and raised third-quarter guidance.
PubMatic Q2 Revenue Rises 11% to $78.6 Million
PubMatic reported Q2 2026 revenue of $78.6 million, an 11% increase from $71.1 million in the year-ago period and well ahead of analyst estimates that clustered around $69–$70 million. Non-GAAP (adjusted) net income was $5.9 million, or $0.12 per diluted share, compared with $2.5 million or $0.05 a year earlier and versus consensus estimates that had anticipated a small loss or near-breakeven result. Adjusted EBITDA climbed to $19.6 million (25% margin) from $14.2 million (20% margin), marking the company’s 41st consecutive quarter of positive adjusted EBITDA. Free cash flow rose 47% to $13.7 million, and operating cash flow increased 36% to $20.2 million. GAAP net loss narrowed to $1.2 million, or $0.03 per share, from $5.2 million, or $0.11 per share.
High-growth areas drove the performance: connected TV (CTV), mobile app, and emerging revenue streams together accounted for approximately 60% of total revenue (roughly double the share three years earlier) and grew nearly 40% year-over-year in aggregate. Mobile-app revenue rose more than 40% and represented about 25% of total revenue. Global CTV revenue increased 13% (approximately 20% of total revenue), with the Americas region up 25%. Emerging revenues (including Activate, commerce media, Connect, and AI solutions) nearly doubled year-over-year to about 15% of total revenue.
AgenticOS, the company’s AI-native platform, scaled to more than 80 fully autonomous campaigns (up from over 30 in Q1) and more than 4,000 AI-powered deals (up from just over 1,000). The company processed nearly 92 trillion impressions, an 18% increase, while cost per million impressions declined 20% on a trailing-twelve-month basis. PubMatic repurchased 2.1 million shares in the quarter (about 4.2% of fully diluted shares as of June 30), leaving $63.6 million remaining under its authorization through the end of 2026. Cash, cash equivalents, and marketable securities stood at $137.5 million with no debt.
For the third quarter, management guided revenue of $75–$77 million (implying roughly 12% year-over-year growth at the midpoint) and adjusted EBITDA of $17–$19 million, both above prior consensus estimates. Full-year capital-expenditure guidance was raised to $20–$25 million to support AI infrastructure. In a separate announcement, long-serving CFO Steve Pantelick said he plans to retire after 15 years; he will remain CFO into the first quarter of 2027 and then serve as a senior adviser through July 1, 2027, while the company searches for a successor.
PubMatic Stock Surges Over 30% on Strong Q2 Results
Investors responded strongly because the results delivered a clear inflection: double-digit revenue growth arrived earlier than the company had previously indicated, profitability and free-cash-flow expansion accelerated, and forward guidance exceeded expectations. The mix shift toward higher-growth CTV, mobile app, and AI/emerging streams reduced dependence on slower traditional channels and demonstrated leverage from prior investments. Aggressive share buybacks and a debt-free balance sheet further supported the valuation reset. After-hours and pre-market trading saw the stock climb sharply (reports ranged from roughly 20% to more than 30%), pushing shares well above the prior 52-week high of $14.04 amid a modestly positive broader market backdrop. The catalyst was almost entirely company-specific rather than macro-driven.
PubMatic’s Shift to CTV, Mobile and AI Powers Growth
PubMatic operates an AI-powered supply-side platform that helps publishers monetize digital advertising inventory across the open internet while giving advertisers greater control and transparency. The company has navigated earlier headwinds, including disruption from a legacy demand-side platform partner, by investing in CTV, mobile apps, and proprietary AI capabilities such as AgenticOS. Over the past three years the contribution of these faster-growing segments has roughly doubled. Management has consistently generated positive adjusted EBITDA and returned capital via buybacks while maintaining a strong cash position and zero debt. The Q2 results validated the strategy and accelerated the timeline for sustained double-digit growth and margin expansion.
What’s Next: PubMatic Focuses on Q3 Guidance and Margin Expansion
Attention turns to execution against the raised Q3 guidance and continued scaling of AgenticOS, CTV, and mobile-app revenue. Investors will watch for further evidence of AI-driven performance gains, the impact of higher CapEx on AI infrastructure (expected payback within about 12 months), and any contribution from political advertising later in the year. The CFO transition will also be monitored for continuity. Full-year margin expansion remains a key management priority as the higher-growth mix continues to scale.
