Equity compensation and insider-transactions analyst

Director exercised 2,000 options and increased direct FAST shareholdings.

The report shows a Fastenal director exercising a stock option for $13.75 per share on 11/18/2025 to acquire 2,000 shares of common stock. This is coded as transaction type "M," indicating an option exercise rather than an open-market purchase or sale. The shares are priced at $39.96 in the acquisition column, tying the option exercise to current share value.

Following the transaction, the director directly holds 56,190 shares, including amounts in a revocable trust and a self-directed IRA, and indirectly holds 13,008 shares through a 401(k) plan. The director also retains 12,948 stock options after the exercise, so additional option-based exposure to Fastenal remains. This appears to be a routine equity compensation event rather than a large change in ownership structure.
