[Form 4] ALLISON TRANSMISSION HOLDINGS, INC. Insider Trading Activity

Rhea-AI Filing Summary

Everitt David C, a director of Allison Transmission Holdings, Inc. (ALSN), reported an acquisition on 08/29/2025 of 95 shares of common stock resulting from dividend equivalent rights tied to previously awarded deferred stock units (DSUs).

Following the acquisition, Mr. Everitt beneficially owns 3,519 shares directly. The Form 4 was executed by an attorney-in-fact on 09/03/2025. The filing discloses the mechanics: dividend equivalent rights accrue and vest with the related DSUs and each right is economically equivalent to one share of common stock.

Insights

Corporate Governance Expert

TL;DR: Small non-cash acquisition from vested DSU dividend equivalents; routine insider disclosure.

The filing documents a standard equity compensation conversion where dividend equivalent rights tied to deferred stock units were settled into 95 shares. This is a common mechanism to compensate directors while preserving cash and aligning interests with shareholders. The resulting beneficial ownership of 3,519 shares is modest for a director and does not indicate a change in control or significant shift in governance influence. Documentation and timely reporting meet Section 16 disclosure expectations.

Securities Analyst

TL;DR: Non-material issuance of 95 shares via dividend equivalents; unlikely to affect valuation or market perception.

The transaction is coded as an acquisition (A) with a price of $0 because it reflects dividend equivalent rights converting into shares rather than a market purchase. The size—95 shares increasing direct ownership to 3,519—is small relative to a public company equity base and therefore has negligible market impact. The form contains the required explanation tying the shares to previously awarded DSUs, supporting transparency for investors and regulators.
