INDIANAPOLIS, February 11, 2025 – Allison Transmission Holdings Inc. (NYSE: ALSN) today reported all-time high full year net sales of $3.2 billion, increasing 6 percent from 2023. Diluted EPS for the year increased 12 percent year over year to a record $8.31.

David S. Graziosi, Chair and Chief Executive Officer of Allison Transmission commented, “Closing out the year, unprecedented demand for Class 8 vocational vehicles persisted in the fourth quarter of 2024, leading to record full year net sales of $1.8 billion in our North America On-Highway end market. Driven by the realization of our growth initiatives, we achieved decade-high full year net sales in our Defense end market and all-time high full year net sales in our Outside North America On-Highway end market.”

Graziosi continued, “In addition to notable top-line performance across multiple end markets, Allison’s full year earnings per share increased 12 percent from 2023 to a company record diluted EPS of $8.31. In 2024, we returned cash to shareholders by increasing our quarterly dividend for the fifth consecutive year while repurchasing over $250 million of our common stock, representing over 3 percent of outstanding shares, and paying down $101 million of existing term loan debt. At the midpoint, we are guiding to another record revenue year for 2025 driven by price increases on certain products, increased demand for Tracked vehicle applications and robust North America vocational demand.”

Use of Non-GAAP Financial Measures

This press release contains information about Allison’s financial results and forward-looking estimates of financial results which are not presented in accordance with accounting principles generally accepted in the United States (“GAAP”). Such non-GAAP financial measures are reconciled to their closest GAAP financial measures at the end of this press release. Non-GAAP financial measures should not be considered in isolation or as a substitute for our reported results prepared in accordance with GAAP and, as calculated, may not be comparable to other similarly titled measures of other companies.

We use Adjusted EBITDA and Adjusted EBITDA as a percent of net sales to measure our operating profitability. We believe that Adjusted EBITDA and Adjusted EBITDA as a percent of net sales provide management, investors and creditors with useful measures of the operational results of our business and increase the period-to-period comparability of our operating profitability and comparability with other companies. Adjusted EBITDA as a percent of net sales is also used in the calculation of management’s incentive compensation program. The most directly comparable GAAP measure to Adjusted EBITDA is Net income. The most directly comparable GAAP measure to Adjusted EBITDA as a percent of net sales is Net Income as a percent of net sales. Adjusted EBITDA is calculated as the earnings before interest expense, net, income tax expense, amortization of intangible assets, depreciation of property, plant and equipment and other adjustments as defined by Allison Transmission, Inc.’s, the Company’s wholly-owned subsidiary, Second Amended and Restated Credit Agreement. Adjusted EBITDA as a percent of net sales is calculated as Adjusted EBITDA divided by net sales.

We use Adjusted Free Cash Flow to evaluate the amount of cash generated by our business that, after the capital investment needed to maintain and grow our business and certain mandatory debt service requirements, can be used for repayment of debt, stockholder distributions and strategic opportunities, including investing in our business. We believe that Adjusted Free Cash Flow enhances the understanding of the cash flows of our business for management, investors and creditors. Adjusted Free Cash Flow is also used in the calculation of management’s incentive compensation program. The most directly comparable GAAP measure to Adjusted Free Cash Flow is Net cash provided by operating activities. Adjusted Free Cash Flow is calculated as Net cash provided by operating activities, after additions of long-lived assets.
