On Feb 2, 2026, Xie exercised 324,285 options at $16.90 and immediately sold 343,106 shares at ~$81–82, netting roughly $28M. This exercise-and-sell pattern has been his primary monetization method.

What It Means

Xie co-founded Fortinet in 2000 and has systematically converted his equity into cash over two decades. His $5.84B in total sales makes him one of the largest insider sellers in the cybersecurity sector. The zero-share position signals a complete exit from direct ownership.

A founder-CTO holding zero shares is unusual. For FTNT investors, this warrants monitoring whether Xie retains unvested options or RSUs — the Form 4 filings show ongoing exercises, suggesting compensation continues even without a direct stake.

What to Watch

• Remaining unvested option grants
• CTO role retention post-exit
• Fortinet board composition changes
• Peer CTO selling at PANW, CRWD
