PubMatic, Inc. Class A (PUBM)

In the past six months, PubMatic's stock has been impacted by Q4 2025 and Q1 2026 earnings reports, both exceeding guidance. Q1 2026 revenue was slightly down, and the company reported a wider GAAP net loss. The stock price as of May 7, 2026, was $10.24, a decline of 6.91% over the past year. Insider selling activity has been observed, and PubMatic filed a lawsuit against Google over alleged anti-competitive behavior in September 2025.

PubMatic's revenue model is exposed to the seasonality and cyclicality of the global advertising market. AdTech businesses typically benefit from seasonality in the last quarter of the year. Economic downturns often lead to cuts in ad budgets, impacting PubMatic's revenue. Specific advertising categories also exhibit seasonality.
