On July 15, 2026, Cloudflare, Inc. CFO Thomas J. Seifert had 2,943 shares of Class A Common Stock withheld at $281.75 per share (about $0.83 million) to cover taxes upon RSU vesting, a non-discretionary event. On July 17, 2026, he exercised 10,000 employee stock options with a $2.04 strike, converting 10,000 Class B shares into 10,000 Class A shares at no stated cost, and simultaneously conducted a series of Rule 10b5-1–planned open-market sales totaling 10,000 Class A shares at weighted-average prices between roughly $266 and $281 per share, generating proceeds of approximately $2.75–$2.80 million. After these transactions, he directly held 113,790 Class A shares, and continued to have substantial additional indirect holdings through various trusts and an entity he controls; the activity is largely compensation- and liquidity-related rather than a pure open-market purchase or discretionary sale of newly acquired equity.
