Allison (ALSN) COO Bohley Receives RSU Vesting; 664 Shares Withheld

What Happened

Bohley G. Frederick, COO, President & BU Leader AT of Allison Transmission Holdings, had equity awards settle on February 19, 2026. A total of 1,607 shares were acquired on vesting: 1,590 restricted stock units (RSUs) and 17 dividend equivalent rights (DERs).
Of those vested shares, 664 shares were withheld by the company to satisfy tax withholding obligations at $117.78 per share, resulting in $78,206 withheld. The settlement/conversion of the RSUs and DERs is reported as derivative conversions at a $0.00 exercise price (routine vesting/conversion, not an open-market purchase or sale).

Key Details

Transaction date: 2026-02-19.
Awards settled: 1,590 RSUs + 17 DERs = 1,607 shares acquired (codes A and M in the filing).
Tax withholding: 664 shares withheld (code F) at $117.78/share = $78,206.
Footnotes: F1 = RSU settlement; F2 = DERs representing dividend equivalents that vest with RSUs; F3 = shares withheld to satisfy tax withholding.
