**Allison Announces First Quarter 2026 Results** 

**\*** **Net Sales of $1,406 million, up 84% year over year, including the addition of the Allison Off-Highway business unit acquired on January 1, 2026** 

**\*** **Net Income of $112 million, 8% of Net Sales** 

**\*** **Diluted EPS of $1.33, Adjusted Diluted EPS of $2.57, up 6% year over year** 

**\*** **Adjusted EBITDA of $362 million, 26% of Net Sales, up 22% year over year** 

**\*** **First quarter results include segment reporting for Allison Transmission and Allison Off-Highway business units** 

**INDIANAPOLIS, May 4, 2026 – Allison Transmission Holdings Inc. (NYSE: ALSN)**, today reported first quarter net sales of $1,406 million with adjusted EBITDA margin of 26 percent and net cash provided by operating activities of $156 million.

David S. Graziosi, Chair, President and Chief Executive Officer of Allison commented, "Encouraging momentum in key end markets supported solid demand for both Allison business units in the first quarter. Despite ongoing geopolitical uncertainty, we will look to capitalize on further improvement in end markets conditions throughout the year, while continuing to integrate the Allison Off-Highway business unit, maintaining focus and confidence in our synergy capture target in support of our long-term growth and value creation strategy. For the first quarter, adjusted diluted EPS was $2.57, with expectation for the acquisition of the Allison Off-Highway business unit to be accretive to net income and diluted EPS in 2026."

Graziosi continued, "During the first quarter, we announced the seventh consecutive annual increase to our quarterly dividend and repurchased more than $20 million of our common stock, demonstrating Allison's consistent commitment to returning cash to shareholders as part of our capital allocation priorities. Also during the quarter, as we progress toward our 2.0x net leverage target with prudent balance sheet management, our strong cash flow generation enabled us to repay $150 million of amounts outstanding under our revolving credit facility."

First quarter results include segment reporting for Allison Transmission, the Company's legacy business, excluding certain costs now accounted for within the Allison Central Group, and Allison Off-Highway, the business acquired from Dana Incorporated on January 1, 2026. The Allison Central Group is a centralized cost center which includes certain functional costs that support the Company's global operations.

**Allison Consolidated First Quarter Financial Results** 

Net sales for the quarter were $1,406 million, including the addition of $673 million in net sales for the Allison Off-Highway business unit.

Gross profit for the quarter was $406 million, an increase of $28 million from $378 million for the same period in 2025. The increase was principally driven by the addition of the Allison Off-Highway business unit, partially offset by decreased gross profit in the Allison Transmission business unit. Gross profit for the quarter was negatively impacted by approximately $76 million of expenses related to the acquisition of the Allison Off-Highway business unit, primarily inventory step-up costs and incremental depreciation expense related to the stepped-up basis in property, plant and equipment. Gross margin for the quarter was 29 percent.

Selling, general and administrative expenses for the quarter were $157 million, an increase of $70 million from $87 million for the same period in 2025. The increase was principally driven by the addition of the Allison Off-Highway business unit, including $21 million of amortization expense for intangible asset recognition and approximately $17 million of one-time acquisition-related integration costs.

------

Engineering – research and development expenses for the quarter were $54 million, an increase of $12 million from $42 million for the same period in 2025. The increase was principally driven by the addition of the Allison Off-Highway business unit, partially offset by reduced product initiatives spending in the Allison Transmission business unit.

Net income for the quarter was $112 million, a decrease of $80 million from $192 million for the same period in 2025. The decrease was principally driven by costs related to the acquisition of the Allison Off-Highway business unit. The year over year decrease in net income was also driven by higher interest expense, net, partially offset by lower income tax expense. Diluted EPS for the first quarter was $1.33.

Excluding the effect of certain non-cash, non-recurring, infrequent or unusual items, including the costs associated with the acquisition of the Allison Off-Highway business unit, adjusted net income, a non-GAAP financial measure, was $216 million for the first quarter and adjusted diluted EPS was $2.57.

Adjusted EBITDA, a non-GAAP financial measure, was $362 million for the first quarter, an increase of $66 million from $296 million for the same period in 2025. Adjusted EBITDA margin for the quarter was 26 percent.

Net cash provided by operating activities for the quarter was $156 million. Adjusted free cash flow, a non-GAAP financial measure, for the quarter was $103 million.

Allison ended the first quarter with $311 million of cash and cash equivalents and $845 million of available borrowing capacity under its revolving credit facility. Allison ended the first quarter with total debt of $4,292 million and net debt of $3,981 million.

During the first quarter, Allison paid a quarterly dividend of $0.29 per share and repurchased over $20 million of its common stock, with $1,171 million of authorization remaining under its stock repurchase program.

**Allison Transmission First Quarter Financial Highlights** 

Net sales for the quarter were $733 million, a 4 percent decrease from the same period in 2025.

Gross profit for the quarter was $356 million, a decrease of $22 million from $378 million for the same period in 2025. The decrease was principally driven by lower volumes and unfavorable direct material costs, partially offset by price increases on certain products. Gross margin for the first quarter was nearly 49 percent.

Selling, general and administrative expenses for the quarter were $65 million, flat from the same period in 2025 when reflecting allocations of certain selling, general and administrative expenses in the Allison Central Group.

Engineering – research and development expenses for the quarter were $39 million, a decrease of $3 million from $42 million for the same period in 2025. The decrease was principally driven by reduced product initiatives spending.

Segment operating profit was $252 million, or 34 percent of net sales, for the first quarter. Adjusted EBITDA, a non-GAAP financial measure, was $276 million for the first quarter. Adjusted EBITDA margin for the quarter was 38 percent.

**Allison Off-Highway First Quarter Financial Highlights**

**Use of Non-GAAP Financial Measures** 

This press release contains information about Allison's financial results and forward-looking estimates of financial results that are not presented in accordance with accounting principles generally accepted in the United States ("GAAP"). Such non-GAAP financial measures are reconciled to their most directly comparable 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 earnings before interest, taxes, depreciation, and amortization ("EBITDA") and adjusted EBITDA as a percent of net sales ("adjusted EBITDA margin") to measure our operating profitability. We believe that adjusted EBITDA and adjusted EBITDA margin 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. Adjusted EBITDA margin is also used in the calculation of management's incentive compensation program. The most directly comparable GAAP measure to adjusted EBITDA and adjusted EBITDA margin is net income or segment operating profit (loss) in the case of our segments and net income as a percent of net sales ("net income margin") or segment operating profit (loss) as a percent of net sales in the case of our segments, respectively. Adjusted EBITDA is calculated as earnings before interest expense, net, income tax expense, amortization of intangible assets, depreciation of property, plant and equipment and other adjustments as defined by the Second Amended and Restated Credit Agreement dated as of March 29, 2019, as amended, governing Allison Transmission, Inc.'s term loans and revolving credit facility. Adjusted EBITDA margin is calculated as adjusted EBITDA divided by net sales.

In addition, we believe adjusted net income, adjusted basic earnings per share attributable to common stockholders ("adjusted basic EPS") and adjusted diluted earnings per share attributable to common stockholders ("adjusted diluted EPS") provide management, investors and creditors with useful measures of our core business performance and trends and increase the period-to-period comparability of our results of operations. The most directly comparable GAAP measure to adjusted net income, adjusted basic EPS and adjusted diluted EPS is net income, basic earnings per share attributable to common stockholders ("basic EPS") and diluted earnings per share attributable to common stockholders ("diluted EPS"), respectively. Adjusted net income is calculated as net income excluding the effect of certain non-cash, non-recurring, infrequent or unusual items such as: amortization related to acquired intangible assets, depreciation of property, plant and equipment related to the stepped-up basis of acquired assets, step-up in basis of acquired inventory, stock-based compensation expense, acquisition-related expenses, impairment charges, other one-off adjustments and the tax effect of the adjustments. Adjusted basic EPS is calculated by dividing adjusted net income by the weighted average shares of common stock outstanding and adjusted diluted EPS is calculated by dividing adjusted net income by the diluted weighted average shares of common stock outstanding.

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 cash used for additions of long-lived assets.

Non-GAAP Financial Information 3 We use adjusted earnings before interest, taxes, depreciation, and amortization ("EBITDA") and adjusted EBITDA as a percent of net sales ("adjusted EBITDA margin") to measure our operating profitability. We believe that adjusted EBITDA and adjusted EBITDA margin 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. Adjusted EBITDA margin is also used in the calculation of management's incentive compensation program. The most directly comparable GAAP measure to adjusted EBITDA and adjusted EBITDA margin is net income or segment operating profit (loss) in the case of our segments and net income as a percent of net sales ("net income margin") or segment operating profit (loss) as a percent of net sales in the case of our segments, respectively. Adjusted EBITDA is calculated as earnings before interest expense, net, income tax expense, amortization of intangible assets, depreciation of property, plant and equipment and other adjustments as defined by the Second Amended and Restated Credit Agreement dated as of March 29, 2019, as amended, governing Allison Transmission, Inc.'s term loans and revolving credit facility. Adjusted EBITDA margin is calculated as adjusted EBITDA divided by net sales. In addition, we believe adjusted net income, adjusted basic earnings per share attributable to common stockholders ("adjusted basic EPS") and adjusted diluted earnings per share attributable to common stockholders ("adjusted diluted EPS") provide management, investors and creditors with useful measures of our core business performance and trends and increase the period-to-period comparability of our results of operations. The most directly comparable GAAP measure to adjusted net income, adjusted basic EPS and adjusted diluted EPS is net income, basic earnings per share attributable to common stockholders ("basic EPS") and diluted earnings per share attributable to common stockholders ("diluted EPS"), respectively. Adjusted net income is calculated as net income excluding the effect of certain non-cash, non-recurring, infrequent or unusual items such as: amortization related to acquired intangible assets, depreciation of property, plant and equipment related to the stepped-up basis of acquired assets, step-up in basis of acquired inventory, stock-based compensation expense, acquisition-related expenses, impairment charges, other one-off adjustments and the tax effect of the adjustments. Adjusted basic EPS is calculated by dividing adjusted net income by the weighted average shares of common stock outstanding and adjusted diluted EPS is calculated by dividing adjusted net income by the diluted weighted average shares of common stock outstanding. 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 cash used for additions of long-lived assets.
