Insights

Equity compensation and insider-trading analyst

Director sells 19,000 AAON shares while retaining sizable equity exposure.

Director Gary D. Fields executed an open-market sale of 19,000 AAON common shares at $140.20 per share on May 29, 2026. Following the transaction, he continues to hold 15,252 shares directly, plus additional indirect holdings.

Filings also show indirect interests in 6,249 shares via a 401(k) Plan and 9,250 shares held as custodian for his grandchildren. These are long-term style vehicles, indicating part of his position is structured for retirement and family purposes rather than short-term trading.

Fields maintains option-based exposure through three Stock Options (Right to Buy) with exercise prices of $82.39, $79.73, and $62.03, expiring between 2033 and 2035 and tied to 7,329, 22,338, and 31,968 underlying shares. This combination of ongoing share ownership and long-dated options suggests the filing reflects portfolio adjustment rather than a full exit.

5 terms

open-market sale financial

"transaction_action: "open-market sale" for 19,000 common shares"

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.

Stock Option (Right to Buy financial

"security_title: "Stock Option (Right to Buy)" with underlying Common Stock"

401(k) Plan financial

"nature_of_ownership: "401(k) Plan" for indirect holdings of common stock"

A 401(k) plan is a workplace retirement account that lets employees set aside part of their pay into a tax-advantaged savings pot, often with employers adding matching contributions — like a workplace piggy bank for future income. It matters to investors because the amount people save and how employers fund these plans influence consumer spending, corporate payroll costs and the flow of money into financial markets, which can affect stock prices and company valuations.

custodian for the benefit of his grandchildren financial

"nature_of_ownership: "Custodian for the benefit of his grandchildren""

exercise price financial

"conversion_or_exercise_price fields such as "82.3900" and "62.0300""

The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
