David S. Graziosi, Chair, President and Chief Executive Officer of Allison commented, “Although 2025 presented meaningful macroeconomic challenges, we remained disciplined and focused on the factors within our control. With a prioritization of cost management and execution aligned with end markets demand conditions, our full year results demonstrate the resilient earnings power of our business in difficult and uncertain operating environments. For the full year, we achieved an Adjusted EBITDA margin of 37.5 percent and generated Adjusted free cash flow of $661 million.”

Graziosi continued, “Earlier this year, we announced the completion of our acquisition of Dana’s Off-Highway business, a transformational moment in Allison history. With the combination of these two industry-leading businesses, we have significantly expanded both our presence in the global mobility market and our portfolio of high-quality and reliable products, creating a platform that will continue to deliver strong financial performance from both organic and inorganic growth. While completing this acquisition last year, we remained committed to our capital allocation priorities, including repurchasing $328 million of our common stock, representing 4 percent of outstanding shares.”

Fourth Quarter Financial Results

Gross profit for the quarter was $354 million, a decrease of $19 million from $373 million for the same period in 2024. The decrease in gross profit was principally driven by lower volumes and unfavorable direct material costs, partially offset by price increases on certain products and lower manufacturing expense. Gross margin for the quarter was 48 percent, an increase of 110 basis points year over year.

Selling, general and administrative expenses for the quarter were $110 million, an increase of $26 million from $84 million for the same period in 2024. The increase was principally driven by the Dana Off-Highway business acquisition-related expenses of approximately $26 million.

Engineering – research and development expenses for the quarter were $44 million, a decrease of $10 million from $54 million for the same period in 2024. The decrease was principally driven by reduced product initiatives spending to align costs and programs across our business with end markets demand conditions.

Net income for the quarter was $99 million, a decrease of $76 million from $175 million for the same period in 2024. The decrease was principally driven by a $29 million loss associated with impairment of long-lived assets and $26 million of expenses related to the acquisition of Dana’s Off-Highway business and lower gross profit.

Net cash provided by operating activities was $243 million, an increase of $32 million from $211 million for the same period in 2024. The increase was principally driven by lower cash income taxes, reduced engineering – research and development spending and lower operating working capital funding requirements, partially offset by lower gross profit and payments for the Dana Off-Highway business acquisition-related expenses.

components used to manufacture or transport our products or those of our customers or suppliers, including as a result of geopolitical risks, natural disasters, extreme weather events, wars and public health crises such as pandemics; global economic volatility; general economic and industry conditions, including the risk of prolonged inflation and recession; labor strikes, work stoppages or similar labor disputes, which could significantly disrupt our operations or those of our principal customers or suppliers; the highly cyclical industries in which certain of our end users operate; uncertainty in the global regulatory and business environments in which we operate; the concentration of our net sales in our top five customers and the loss of any one of these; cybersecurity risks to our operational systems, security systems or infrastructure owned by us or our third-party vendors and suppliers; the failure of markets outside North America to increase adoption of fully automatic transmissions; the success of our research and development efforts, the outcome of which is uncertain; U.S. and foreign defense spending; risks associated with our international operations, including acts of war and increased trade protectionism and tariffs; the discovery of defects in our products, resulting in delays in new model launches, recall campaigns and/or increased warranty costs and reduction in future sales or damage to our brand and reputation; our ability to identify, consummate and effectively integrate acquisitions and collaborations; and risks related to our indebtedness.

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.
