Allison (ALSN) Director Philip J. Christman Receives RSUs

What Happened

Philip J. Christman, a director of Allison Transmission Holdings, had restricted stock units (RSUs) that vested and were settled on May 6, 2026, resulting in 1,586 shares being acquired (1,570 RSUs + 16 dividend equivalents). He also received a 92-share stock retainer on May 6, 2026 and was granted 1,503 new RSUs on May 7, 2026.
No cash purchase or open-market sale occurred. The vested RSUs converted to common shares (reported as exercise/conversion of derivatives, Code M), and new RSUs were awarded (Code A). Based on closing prices cited in the filing, these movements are roughly: 1,586 shares ≈ $202,500; 1,503 RSUs ≈ $184,900 (grant value based on $123.02); and the 92-share retainer ≈ $11,758 (based on $127.70).

Key Details

Transaction dates and types:
- 2026-05-06: 92 shares acquired (award/retainer, Code A) — calculated using $127.70 (F2).
- 2026-05-06: 1,586 shares acquired (exercise/conversion of RSUs/dividend equivalents, Code M) — includes 1,570 RSUs that vested and 16 dividend equivalents (F3–F8).
- 2026-05-07: 1,503 RSUs granted (Code A) — number calculated using $123.02 (F11); these RSUs vest at the next annual meeting (F10).
The filing shows separate “disposed” entries for 1,570 and 16 derivative units — these reflect the conversion/cancellation of the RSU derivative rights when they settled into common shares (not a sale of shares).
Footnotes: quarterly director retainer paid in cash or stock at the director’s discretion (F1); each RSU equals one share and earns dividend equivalents (F5, F7); the 1,503 RSUs are the annual non-employee director equity award (F9).
Shares owned after the transactions are not included in the provided excerpt — see the full Form 4 for total beneficial ownership.
Timeliness: Transactions on May 6 were reported on May 8, 2026 — appears timely (filed within the SEC’s reporting window).

Context

RSU settlements and grants are routine compensation events for non-employee directors and do not represent open-market buying or selling intentions.
“Exercise/conversion” (Code M) here means the derivative RSU rights were converted into common shares upon vesting; no cash proceeds were reported.
Purchases are generally more informative for sentiment than routine awards; these entries mainly reflect compensation and scheduled vesting.
