Thompson Rebecca 4/A

What Happened
Rebecca Thompson, Chief Accounting Officer of AAON, exercised 7,292 stock options on April 23, 2026 at an exercise price of $29.48 per share (cost $214,968) and then sold the 7,292 shares in the open market at a weighted-average price of $100.10 per share, generating proceeds of roughly $729,929. The filing shows both the option exercise (transaction code M) and the resulting sale (transaction code S), indicating a cashless exercise followed by an immediate disposition.

Key Details

• Transaction date: April 23, 2026.
• Exercise: 7,292 shares at $29.48 each — total exercise cost $214,968 (coded M).
• Sale: 7,292 shares at a weighted-average price of $100.10 — total proceeds ~$729,929 (coded S).
• Footnote: The sale was executed in multiple trades at prices between $100.00 and $100.25; $100.10 is the weighted average. Reporting person will provide detailed trade-level info on request (footnote F1).
• Filing status: This Form 4 is amended solely to correct an inadvertent omission of the Rule 10b5-1(c) checkbox designation (indicating a planned trade).
• Shares owned after transaction: Not specified in the provided filing.

Context
Because the options were exercised and the resulting shares were sold the same day, this is effectively a cashless exercise rather than a new long-term purchase signal. The amendment to add the Rule 10b5-1 designation suggests the sale may have been executed under a prearranged trading plan; the filing does not provide motive or additional context beyond the transactions.
