PubMatic is an independent sell-side advertising platform that just posted its first double-digit growth quarter after a year of demand-side contraction, and the print arrives with a mix that looks different from the open-web exchange the market used to price. Connected television, mobile app, and emerging products now account for about 60% of revenue and grew nearly 40% as a group. That mix, not a rebound in commodity display, is the case that the slump is finished. The counterargument is that agentic products remain early and unseparated from older emerging lines, so the equity may be paying for a product cycle that is still a campaign count rather than a disclosed take-rate.
The second-quarter beat ended a three-quarter decline and produced operating leverage that the first half still does not fully show. Adjusted EBITDA rose 38%, yet first-half adjusted earnings sat slightly below the year-ago half because the opening quarter still carried the hangover. Three named buyers still hold 59% of receivables. Trailing publisher retention printed at 98%. Mix and cash are improving while concentration and GAAP profitability have not yet confirmed that the recovery is broad.
Revenue reached $79 million and cleared the May outlook by a wide margin, returning double-digit growth a quarter earlier than management had framed. Third-quarter guidance of $75 million sits below the quarter just printed even as the year-over-year rate stays in double digits. The next two prints decide whether World Cup, Prime Day, and midterm political spend were a bridge or a one-off, and whether AgenticOS graduates from case studies into a disclosed revenue line.
