BARBOUR D. SCOTT 4

What Happened

Scott Barbour, a director of Allison Transmission Holdings, Inc. (ALSN), was granted 3 dividend-equivalent awards tied to previously issued restricted stock units (RSUs) on 2026-05-29. The Form 4 reports these as a derivative award (code A) of 3 units at $0.00 — the filing shows no cash purchase price because these are dividend-equivalent rights that accrue with the RSUs.

Key Details

• Transaction date: 2026-05-29; Form 4 filed: 2026-06-02 (filed within the typical two-business-day window).
• Transaction type/code: Award (A) — derivative dividend-equivalent rights tied to RSUs.
• Quantity/pricing: 3 units reported at $0.00 on the Form 4.
• Shares owned after transaction: Not specified in the provided filing.
• Footnote: F1 — the dividend-equivalent rights accrue on previously awarded RSUs and vest proportionately with those RSUs; each dividend equivalent equals the economic equivalent of one share of common stock.

Context

Dividend-equivalent rights are a common, non-cash award that mirror dividends on RSUs and typically convert to shares (or cash) as the underlying RSUs vest. This is an issuance of derivative compensation, not an open-market purchase or sale, and does not by itself indicate a buy/sell signal.
