VP Engineering/CTO Michael Xie sold 3,907 shares at $146.44 avg via scheduled 10b5-1 plan; minimal position impact on 9.92M holdings.

Michael Xie executed 5 separate sales totaling 3,907 shares for $572,143.68 on 2026-06-03 under a pre-arranged 10b5-1 trading plan adopted 2026-03-04, representing a -0.0% reduction in his 9.92M share post-transaction holdings. The transaction was scheduled, not discretionary. Across his same-ticker history at FTNT, Xie's 5 prior sales showed mixed results: three February 2026 sales returned +0.6%, +1.4%, and +2.2% over 30 days, while two August 2025 sales returned -21.4% and -22.6% over the same period. Given the 10b5-1 structure, the timing of this sale relative to FTNT's +64.1% 30-day and +73.5% 90-day price appreciation cannot be attributed to insider discretion or foresight. The sale occurred at $146.44 average, -1.7% from the 52-week high of $149.03.

Xie executed 3 separate sales totaling 343,106 shares for $27,935,332.53, bringing post-transaction holdings to 10,210,282 shares. The blended average sale price of $81.42 exceeds the current price of $79.30, and the stock is -30.8% from its 52-week high of $114.57. At Fortinet, Xie's prior 5 trades show mixed timing: 3 of the 5 prior sales were well-timed (negative 90-day returns ranging from -12.2% to -12.6% on 2025-08-04 sales), while 2 sales in March 2025 occurred near a local bottom (one with +6.2% 90-day return). His cross-ticker track record over 19 prior sells shows a 42.11% well-timed rate with an average 90-day return of +8.8%, indicating historically poor timing across broader activity. This filing occurs as FTNT trades well below its 52-week high, with the insider retaining substantial post-transaction holdings (10.21M shares).

VP Engineering Xie Michael sells 476,596 shares (476.6K) for $46.9M at blended $98.48; retains 9.73M shares

Xie Michael, VP Engineering & CTO, executed 3 separate sales on 2025-08-04 totaling 476,596 shares for $46,936,042.91 at prices ranging from $97.39 to $98.93, reducing his holdings from 10,207,156 to 9,730,560 shares (-4.7%). The sales occurred at a blended average price of $98.48, which is currently 2.4% above the stock's present price of $96.21, placing these transactions near a near-term local peak. Across his prior 5 sales at FTNT, all subsequent 90-day returns were positive (ranging from +2.3% to +6.2%), meaning the stock consistently rose after he sold—a pattern of poorly-timed execution on this ticker. His cross-ticker track record shows an average 90-day return of +12.7% after sells with a well-timed rate of 31.25%, but his same-ticker history at FTNT reveals a 0% well-timed rate, suggesting his selling pattern at this security has not preceded downturns. The transaction occurs as FTNT trades 16% below its 52-week high and down 8.9% over the past 30 days, though the company maintains strong fundamentals with $1.5B in quarterly revenue, $433.4M in net income, and 12.3% annual revenue growth.

His cross-ticker track record shows prior sells averaging +14.2% 90-day returns with a 55.56% well-timed rate, but at FTNT specifically his prior 5 sales showed mixed outcomes: 3 of 5 achieved negative 90-day returns (well-timed), while 2 achieved gains above +35%. Fortinet's fundamentals remain solid with annual revenue growth of +20.1%, a P/E of 45.30, and the stock trading 6.0% below its 52-week high of $82.87, suggesting the company operates in a growth trajectory despite current market positioning.
