Allison Transmission Announces Second Quarter 2021 Results

• Net Sales of $603 million, up 60% year-over-year

• Net Income of $110 million, 18% of Net Sales, up over 375% year-over-year

• Adjusted EBITDA of $213 million, 35% of Net Sales

• Diluted EPS of $1.01

INDIANAPOLIS, July 28, 2021 – Allison Transmission Holdings Inc. (NYSE: ALSN), a leading designer and manufacturer of conventional and electrified vehicle propulsion solutions and the largest global manufacturer of medium- and heavy-duty fully automatic transmissions for commercial and defense vehicles, today reported a 60 percent increase in net sales from the same period in 2020, as the recovery in customer demand and the global economy continue to strengthen, despite ongoing industry production constraints due to global supply chain challenges.

Year-over-year results were led by an 84 percent increase in net sales in the North America On-Highway end market and a 63 percent increase in net sales in the Outside North America On-Highway end market as a result of the continuing recovery in global on-highway customer demand following the pandemic-related disruptions experienced in 2020. Service Parts, Support Equipment & Other end market net sales were up 44 percent from the same period in 2020 principally driven by higher demand for North America service parts, aluminum die cast components and support equipment.

Net sales for the quarter were $603 million. Net income for the quarter was $110 million. Diluted EPS for the quarter was $1.01. Adjusted EBITDA, a non-GAAP financial measure, for the quarter was $213 million. Net cash provided by operating activities for the quarter was $131 million. Adjusted free cash flow, a non-GAAP financial measure, for the quarter was $95 million.

David S. Graziosi, Chairman and Chief Executive Officer of Allison Transmission commented, “Allison’s second quarter 2021 results reflect an unprecedented recovery in global markets. Customer demand is quickly nearing pre-pandemic levels, and despite broad challenges to global supply chains, industry production is recovering. I am extremely proud of the resilience and dedication demonstrated by the Allison team and extended family throughout this critical and historic time to ensure the continuous delivery of the Allison Brand Promise.

Graziosi continued, “As a result of the ongoing global economic recovery, we are reaffirming the 2021 guidance ranges released to the market on April 28. Finally, during the second quarter, we continued our well-defined approach to capital allocation by settling $130 million of share repurchases, representing 3 percent of outstanding shares, and paying a quarterly dividend of $0.19 per share. Notably, Allison has repurchased over 50 percent of outstanding shares since its 2012 initial public offering.”

Second Quarter Financial Highlights

Gross profit for the quarter was $288 million, an increase of 75 percent from $165 million for the same period in 2020. Gross margin for the quarter was 47.8 percent, an increase of 400 basis points from a gross margin of 43.8 percent for the same period in 2020. The increase in gross profit was principally driven by higher net sales, 2020 restructuring charges that did not recur in 2021 and price increases on certain products partially offset by higher manufacturing expense commensurate with higher net sales and unfavorable material costs.

Selling, general and administrative expenses for the quarter were $80 million, an increase of $11 million from $69 million for the same period in 2020. The increase was principally driven by higher incentive compensation expense and higher commercial activities spending partially offset by the impact of 2020 restructuring charges.

Engineering – research and development expenses for the quarter were $41 million, an increase of $3 million from $38 million for the same period in 2020. The increase was principally driven by increased product initiatives spending partially offset by the impact of 2020 restructuring charges.

Net income for the quarter was $110 million, an increase of $87 million from $23 million for the same period in 2020. The increase was principally driven by higher gross profit partially offset by higher selling, general and administrative expenses and increased product initiatives spending.

Net cash provided by operating activities was $143 million, an increase of $51 million from $92 million for the same period in 2020. The increase was principally driven by higher gross profit and lower cash interest expense partially offset by higher operating working capital requirements, higher cash income taxes, increased product initiatives spending and higher commercial activities spending.

Second Quarter Non-GAAP Financial Measures

Adjusted EBITDA for the quarter was $213 million, an increase of $98 million from $115 million for the same period in 2020. The increase in Adjusted EBITDA was principally driven by higher gross profit partially offset by increased incentive compensation expense, increased product initiatives spending and higher commercial activities spending.

Adjusted free cash flow for the quarter was $95 million, an increase of $28 million from $67 million for the same period in 2020. The increase was principally driven by higher net cash provided by operating activities partially offset by increased capital expenditures.

Full Year 2021 Guidance Update

We are reaffirming the full year 2021 guidance ranges released to the market on April 28 for Net Sales, Adjusted EBITDA, Net Cash Provided by Operating Activities, Adjusted Free Cash Flow and Capital Expenditures. Allison expects 2021 Net Sales in the range of $2,325 to $2,475 million, Net Income in the range of $395 to $465 million, Adjusted EBITDA in the range of $795 to $885 million, Net Cash Provided by Operating Activities in the range of $585 to $655 million, Adjusted Free Cash Flow in the range of $415 to $475 million and Capital Expenditures in the range of $170 to $180 million.

Our 2021 net sales guidance continues to reflect higher demand in the global On-Highway, Service Parts, Support Equipment & Other and North America Off-Highway end markets as a result of the ongoing global economic recovery and price increases on certain products. Our full year 2021 guidance also assumes the continuation of industry production constraints and global supply chain challenges for the foreseeable future.

Forward-looking statements are not guarantees of future performance and involve known and unknown risks. Factors which may cause the actual results to differ materially from those anticipated at the time the forward-looking statements are made include, but are not limited to: the duration and spread of the COVID-19 pandemic, including new variants of the virus and the pace and availability of vaccines, mitigating efforts deployed by government agencies and the public at large, and the overall impact from such outbreak on economic conditions, financial market volatility and our business, including but not limited to the operations of our manufacturing and other facilities, our supply chain, our distribution processes and demand for our products and the corresponding impacts to our net sales and cash flow; increases in cost, disruption of supply or shortage of labor, freight, raw materials or components used to manufacture or transport our products, including as a result of the COVID-19 pandemic; risks related to our substantial indebtedness; our participation in markets that are competitive; the highly cyclical industries in which certain of our end users operate; uncertainty in the global regulatory and business environments in which we operate; our ability to prepare for, respond to and successfully achieve our objectives relating to technological and market developments, competitive threats and changing customer needs; the concentration of our net sales in our top five customers and the loss of any one of these; 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 increased trade protectionism; general economic and industry conditions; 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; labor shortages, labor strikes, work stoppages or similar labor disputes, which could significantly disrupt our operations or those of our principal customers or suppliers; our intention to pay dividends and repurchase shares of our common stock and other risks and uncertainties associated with our business described in our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. Although we believe the expectations reflected in such forward-looking statements are based upon reasonable assumptions, we can give no assurance that the expectations will be attained or that any deviation will not be material.

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

3

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, 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 the 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, excluding non-recurring restructuring charges, after additions of long-lived assets.

The most directly comparable U.S. generally accepted accounting principles (“GAAP”) measure to Adjusted EBITDA and Adjusted EBITDA as a percent of net sales is Net income and Net income as a percent of net sales, respectively. Adjusted EBITDA is calculated as the earnings before interest expense, 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, excluding non-recurring restructuring charges, after additions of long-lived assets.
