Michael Xie

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.

VP Engineering & CTO Michael Xie sold 343,106 shares at $81.01–$82.28 for $27.9M on 2026-02-02, reducing FTNT holdings 3.3%.

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.

Fortinet CTO Michael Xie sold 326,784 shares for $32,079,516.65 across 5 transactions on 2025-03-11

Michael Xie, VP of Engineering & CTO, executed 5 separate sales totaling 326,784 shares for $32,079,516.65 on 2025-03-11, reducing his holdings by 2.9% to 11.00M shares. The blended average price of $98.17 occurs as the stock has declined 8.7% over the prior 30 days and trades 14.2% below its 52-week high of $114.57. Reviewing Xie's historical pattern at Fortinet, 4 of his 5 prior sales (2024-11-04, 2024-08-02) yielded substantial positive 90-day returns (24.2% to 40.2%), indicating poor timing relative to subsequent price appreciation; only 1 of 5 prior Fortinet sales was well-timed. His cross-ticker track record shows an average 90-day return of +16.7% after sells (well-timed rate 45.45%), but the same-ticker outcomes indicate these sales have historically preceded rallies rather than declines. This sale occurs while Fortinet maintains strong fundamentals: $1.5B quarterly revenue, +12.3% annual growth, and $539.9M net income, though valuation at P/E 35.48 is elevated.

FTNT VP/CTO Xie Michael sold 24,712 shares for $1,948,883.30 on 2024-11-04 at blended $78.86

Xie Michael, VP of Engineering and CTO, executed two separate sales on 2024-11-04 totaling 24,712 shares for $1,948,883.30, representing a 0.2% reduction in his 10.83M-share post-transaction holdings. The sales occurred at $78.67 and $79.09 per share, compared to the current price of $77.92, suggesting execution near recent levels. 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.

FTNT VP Engineering/CTO Michael Xie sold 24,712 shares for $1.4M; prior 5 FTNT trades 100% well-timed at 90-day mark

Michael Xie sold 24,712 shares across 2 separate transactions for a total of $1,386,707.23 at a blended average price of $56.11. His prior 5 sales at FTNT show a perfect 100% well-timed pattern at the 90-day mark, with 90-day returns ranging from -10.3% to -1.9%, suggesting consistent ability to precede downturns. More broadly, his cross-ticker track record across 7 prior sells shows an average 90-day return of +7.0% with a 71.43% well-timed rate, though this is less predictive for single-ticker activity. The current stock price of $56.51 is -27.6% from its 52-week high of $78.03 and -7.0% lower over the past 30 days, reflecting recent weakness that aligns with his historical pattern. His post-transaction holdings of 10.85M shares represent a -0.2% reduction, leaving him with substantial exposure to FTNT despite the sale.
