O'Brien Michael Graham, the CFO of GTM, has filed 88 Form 4 transactions across two companies, but the pattern is almost entirely one-directional. His total open-market purchases are zero, while his total open-market sales amount to $20,002.50. That single sale occurred on August 6, 2026, and represents the only transaction coded as a discretionary "S" in the recent filings.
The bulk of his activity is mechanical. The recent trades show a recurring monthly cycle of option exercises (coded "M", valued at $0) paired with shares withheld to cover taxes (coded "F"). For example, on August 1, 2026, he exercised options and had $201,540.90 withheld for tax purposes, alongside a smaller $2,501.40 withholding. Similar patterns appear on July 1, 2026 ($96,048.33 withheld), and smaller amounts on June 1, May 1, and September 1. There is also a grant (coded "A") on May 29, 2026, with no cash value.
The August 6 sale of $20,002.50 is small relative to the tax-withholding figures. It is the only open-market sale in the recent window, and there are no open-market buys at all. The compensation-related transactions, including the option exercises and tax withholdings, dominate the filing history. The data shows a CFO who receives equity grants and exercises options on a schedule, but who has not used his own cash to buy shares in the open market.
