What insider transaction did AAON (AAON) report for EVP Gordon Douglas Wichman?

AAON’s Executive Vice President Gordon Douglas Wichman reported a tax-related disposition of 102 common shares at $88.33 per share. The F-code indicates shares were withheld to cover tax obligations, not sold in an open-market trade, making this a routine compensation-related event.

How many AAON shares does Gordon Douglas Wichman hold after this Form 4 filing?

Following the reported tax-withholding transaction, Gordon Douglas Wichman holds 10,217 AAON common shares directly. He also has indirect ownership of 4,510 shares through a 401(k) plan, providing a combined visible equity stake alongside his substantial outstanding stock option awards.

What does the F transaction code mean in the AAON Form 4 filing?

The F code in the AAON Form 4 indicates shares were disposed of to pay exercise price or tax liability by delivering securities. Here, 102 shares at $88.33 were used for tax withholding, which differs from a discretionary open-market sale and carries limited informational value on sentiment.

What stock options does AAON EVP Gordon Douglas Wichman retain after the reported transaction?

Gordon Douglas Wichman retains several AAON stock option grants. These include rights over 24,250 underlying common shares at a $27.58 exercise price expiring March 11, 2029, plus additional grants with exercise prices up to $82.39 and expirations extending through March 11, 2035.

Is the AAON EVP’s Form 4 transaction a significant insider sale?

The Form 4 shows a small 102-share tax-withholding disposition at $88.33, not an open-market sale. Because the shares covered tax obligations and Wichman still holds over 10,000 shares plus sizable options, this filing appears routine rather than a major change in insider exposure.
