Allison (ALSN) Director Perna Gustave Converts RSUs, Receives Grant

What Happened

Perna Gustave, a director of Allison Transmission Holdings, had derivative awards convert into common shares and received a new RSU grant. On May 6, 2026 the filing shows 1,586 derivative units converted into shares (1,570 RSUs plus 16 dividend equivalents). The same filing reports dispositions of 1,570 and 16 derivative units on May 6 (these appear alongside the conversions). On May 7, 2026 Gustave was granted 1,503 RSUs (reported as an award), a grant whose reported number was calculated using a $123.02 share price (implying an approximate grant value of $184,899).

Key Details

Transaction dates: Conversions/dispositions — May 6, 2026; Grant — May 7, 2026. Form filed May 8, 2026 (timely).
Transaction codes: M = exercise/conversion of derivative (conversion of vested RSUs and dividend equivalents); A = grant/award (new RSUs).
Share counts reported: 1,586 shares acquired via conversion (includes 16 dividend equivalents); 1,570 and 16 units reported as disposed (same dates); 1,503 RSUs granted on May 7.
Shares owned after the transaction: not shown in the provided filing details.
Footnotes: RSUs represent a contingent right to one share; the 1,570 RSUs were granted May 8, 2025 and vested May 6, 2026; 16 dividend equivalents vested with the RSUs; the new RSUs are the director’s annual award and vest at the next annual meeting; grant count based on $123.02 closing price.
Possible meaning of simultaneous “disposed” entries: filings commonly show conversions and concurrent net settlement/withholding (e.g., to cover taxes) when RSUs vest — the form here reports both conversion and disposition line items.

Context

These transactions are RSU settlements and a standard non-employee director equity award, not open-market buys or sales of previously held stock. RSU conversions and grant awards are routine compensation events for directors and don’t by themselves indicate buy/sell market sentiment.
The filing is timely (filed two days after the primary transaction date), and the details align with the company’s director compensation policy and RSU vesting schedule.
