Fortinet, Inc. 4

Fortinet CEO Ken Xie had RSUs vest, exercised 155,000 options at $22.90, and sold about 161,482 shares of common stock around $160–$164 per share under a 10b5-1 plan while retaining over 57.8 million shares in total.

On this Form 4, Fortinet President & CEO Ken Xie reported routine equity compensation activity combined with sizable programmatic sales. On August 1, 2026, several tranches of previously granted RSUs vested, resulting in the acquisition of 6,260, 4,558, and 2,275 shares of Fortinet common stock at no cost, while 6,611 shares were simultaneously withheld at a price of about $161.95 per share to cover tax obligations. On August 3, 2026, Xie exercised a fully vested nonqualified stock option for 155,000 shares at an exercise price of $22.90 and then sold multiple blocks of common stock under a Rule 10b5-1 trading plan: 18,409 shares at a weighted average price of $160.1376, 19,647 shares at $160.823, 7,350 shares at $161.8201, 67,971 shares at $163.0821, 47,943 shares at $163.91, and 162 shares at $164.49. The RSU vestings and tax withholdings are non-open-market equity compensation events, while the option exercise paired with roughly 161,000 shares of open-market sales constitutes a large, pre-planned liquidity transaction. Following these transactions, Xie continued to beneficially own approximately 52,972,372 shares directly and an additional 4,848,774 shares indirectly through his spouse, representing a very substantial ongoing ownership stake in Fortinet.
