Fortinet (FTNT) CTO Michael Xie Exercises RSUs, Sells 3,121 Shares

What Happened

• Michael Xie, VP Engineering & CTO and a company director at Fortinet (FTNT), had 6,306 restricted stock units (RSUs) convert to shares on Aug 1, 2026 (reported as exercise/conversion, code M). Of those, 3,185 shares were relinquished/withheld to cover tax obligations at $161.95 per share ($515,811 total; exempt payment/tax withholding per footnote F2).
• The remaining 3,121 shares were sold in the open market on Aug 3, 2026 (sales at prices between $160.36 and $163.98), producing gross proceeds of about $507,574. Combined value of withheld shares and open-market sales is roughly $1,023,385. These sales were reported under the applicable transaction codes (S for sale, F for tax withholding).

• Notable footnotes: F13 clarifies each RSU = right to one share; F2 describes the tax-withholding/cancelled-share process; F3 notes the sales were made pursuant to a Rule 10b5-1 trading plan (adopted Mar 4, 2026); F14–F17 describe the RSU vesting schedule/terms.

Context

• These were RSU vesting and settlement transactions (derivative/conversion), not open-market purchases. The withholding of shares to pay taxes is a routine, exempt transaction when RSUs vest (often called a cashless/withholding settlement). The subsequent open-market sales were effected under a 10b5-1 plan, which is a pre-arranged trading plan. Such transactions are typically routine and meant to satisfy tax obligations or diversify holdings rather than indicating a change in the insider’s private view of the stock.
