Allison (ALSN) COO G. Frederick Bohley Receives RSUs; Tax Withholding

What Happened
G. Frederick Bohley, COO, President & BU Leader at Allison Transmission (ALSN), had restricted stock units (RSUs) and dividend equivalent rights (DERs) settle on Feb 21–22, 2026. A total of 5,301 shares were delivered on settlement (2,273 on Feb 21 and 3,028 on Feb 22). To cover tax withholding, ALSN withheld 960 shares (Feb 21) and 1,294 shares (Feb 22) and treated those withholdings as disposals at $118.85 per share, generating proceeds of $114,096 and $153,792 respectively (total ~$267,888). Several filing lines show the derivative-to-share conversions recorded with $0 exercise price (typical for RSU/DER settlements).

Context
This transaction is a routine equity award settlement (RSUs and associated DERs) with company withholding used to cover tax obligations — not an open-market purchase or discretionary sale. The derivative entries reflect conversion/settlement of RSUs/DERs (M codes) and the tax withholding (F code) represents shares retained/sold to satisfy taxes. Such vesting/withholding transactions are standard compensation events and do not by themselves indicate a change in the insider’s view of the company.
