PubMatic, Inc. (NASDAQ: PUBM) saw an insider sale this week as Chief Growth Officer Paulina Klimenko sold 12,091 shares of the company’s Class A common stock on April 2, 2026, for roughly $98,823, according to a Form 4 filing with the Securities and Exchange Commission.
The disposition was carried out at a weighted average price of $8.1733 per share, with individual trade prices reported in the filing between $7.98 and $8.27. The company’s stock is currently quoted at $8.27, a level noted in the filing as below InvestingPro’s Fair Value estimate and identified in the filing as an undervalued name within the digital advertising sector.
The Form 4 filing specifies that the shares sold were used to satisfy tax withholding requirements associated with the vesting and settlement of restricted stock units. The sale, therefore, was reported as a tax-related disposition rather than an open-market sell for other stated reasons.
The insider activity followed a series of equity events on April 1, 2026. Klimenko exercised options to acquire 33,531 shares of Class A common stock at an exercise price of $0. On the same date she also exercised options tied to restricted stock units: 6,583; 6,484; 5,364; and 15,100 RSUs, each of which represents the right to receive one share of PubMatic’s Class A common stock upon settlement, the filing shows.
Separately, PubMatic released fourth-quarter 2025 financial results that the filing describes as strong. The company reported notable expansion in its Connected TV and mobile app businesses and cited the rollout of new AI-driven solutions as a contributor to the performance. Market reaction to the earnings was positive, including a premarket uptick in the stock, and the earnings release was characterized as reinforcing PubMatic’s stated growth strategy.
