Ryan Christopher Michael

Insider trading profile for Ryan Christopher Michael at Gevo, Inc. (GEVO) -- 269 transactions spanning 2011-03-23 to 2026-06-12. 1,385,719 shares sold vs 9,600 shares acquired -- a 144:1 sell-to-buy ratio. Transaction pattern: The June 2026 cluster shows continued heavy selling: 2026-06-12 (S code, 35,196 shares at $1.43) and 2026-05-27 (S code, 87,700 shares at $1.76) -- total single-day volume of ~123K shares near the stock's current $1-$2 trading range, representing outsized liquidation. 2025 cluster: 2025-10-15 (100,000 shares at $2.82), 2025-09-04 (1,683 shares at $1.63), 2025-08-05/01 (86,463 shares at $1.23-$1.25). Acquisition events are concentrated in the 2022-2024 period and are all marked with null prices and large denominators -- consistent with RSU/performance-vesting events, not open-market conviction: 2025-06-09 (A code, 626,618 + 210,084 = 836,702 shares, null prices -- likely exercise or vesting), 2024-09-01 (10,000 shares), 2024-05-22 (550,000 + 550,000 = 1.1M shares, null prices), 2023-08-03 (266,220 + 266,220 = 532,440 shares at $0 -- exercise price or grant). Buying in the last two years has been almost entirely A-code events at null price. The open-market sell pattern is remarkably consistent: whenever GEVO trades above $2 (2023-2025), insider sells large blocks; at $1.43 range (2026), selling continues. There is no accumulation period visible in the data. The A-code acquisitions (RSU vesting) automatically offset the sell pattern in net-share terms and should not be interpreted as bullish. Bearish read -- without any acquisition events that can be read as discretionary insider confidence, this is a textbook systematic offloading pattern consistent with either (a) a major shareholder seeking liquidity, (b) an officer exercising and immediately selling vested equity as part of compensation, or (c) declining fundamental confidence in a company whose stock has declined significantly from highs. GEVO's business (renewable hydrocarbons, SAF fuel technology) has faced technical and market headwinds; consistent insider offloading across every price regime is a significant negative signal.
