Grunst Martin E, EVP and CFO of BOK Financial Corporation (BOKF), has demonstrated a consistent pattern of selling activity in company stock over the past two years, with no recorded purchases in the same period. According to SEC Form 4 filings, Grunst executed multiple sales totaling $137,389.38, primarily through dispositions (coded "D") and tax-related transactions (coded "F"). Notably, on February 18, 2026, Grunst sold shares worth $27,376.86, mirroring a similar transaction earlier that month. This follows a January 2026 sale of $18,101.60 and a February 2025 sale of $17,998.35, suggesting a recurring pattern of mid-five-figure dispositions around the first quarter.
The transactions appear tied to routine equity events rather than discretionary trades, as evidenced by the prevalence of tax withholding ("F") and derivative transactions ("A") with zero reported value. Grunst’s sales have been concentrated exclusively in BOKF stock, with no diversification into other securities. While the dollar amounts are modest relative to executive compensation norms, the absence of buy-side activity and the timing of sales—often clustered in early calendar years—point to a structured divestment approach, possibly linked to vesting schedules or tax obligations. The filings show no recent transactions beyond February 2026, leaving the current position unclear.
