  1. Settlement of restricted stock units ("RSUs") and related dividend equivalents. Includes 16 dividend equivalents. Each RSU represents a contingent right to receive one share of Allison Transmission Holdings, Inc.'s (the "Company") common stock. On May 8, 2025, the reporting person was granted 1,570 RSUs that vested on May 6, 2026. Each dividend equivalent right is the economic equivalent of one share of the Company's common stock. The dividend equivalent rights accrued on previously awarded RSUs and vested on May 6, 2026. The RSUs represent the reporting person's annual equity award under the Company's Ninth Amended and Restated Non-Employee Director Compensation Policy. The RSUs vest on the date of the next annual meeting of the stockholders of the Company. Unvested RSUs earn dividend equivalents when dividends are declared on the Company's common stock. The number of RSUs received was calculated based on $123.02, which was the closing price of the Company's common stock on the date of grant.

Restricted Stock Units financial
"On May 8, 2025, the reporting person was granted 1,570 RSUs that vested"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
dividend equivalents financial
"Unvested RSUs earn dividend equivalents when dividends are declared"
Payments tied to employee or contractor equity awards that mirror the cash dividends paid on the company’s stock; they give the holder the same economic benefit as owning the shares without transferring actual shares—often paid in cash or additional award units when the award becomes payable. Investors care because these payments affect a company’s compensation costs, cash flow and potential share dilution, and they signal how management is being rewarded and aligned with shareholders.
dividend equivalent rights financial
"Each dividend equivalent right is the economic equivalent of one share"
Dividend equivalent rights are promises that mirror the cash payments shareholders get from a company’s profits, but they are paid to holders of certain awards (like stock options or restricted stock units) rather than to actual shares. Think of them as a paycheck top‑up that matches dividends while the award is not yet a real stock, and they matter to investors because they add to employee compensation costs and potential share dilution, affecting company profitability and per‑share value.
