Thompson Rebecca 4/A

What Happened
Rebecca Thompson, AAON's Chief Accounting Officer, exercised options for 2,287 shares at $29.48 per share (total exercise cost $67,421) on April 21, 2026, and sold those 2,287 shares the same day in open-market trades for a weighted average price of $100.11 per share (total proceeds ≈ $228,952). This sequence—exercise followed by an immediate sale—is effectively a cashless exercise resulting in a net sale.
