Item 1A. Ri sk Factors Except as set forth below, there have been no material changes from our risk factors as previously reported in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024 as filed with the Securities and Exchange Commission on February 13, 2025. The following risk factors have been added: Risks Related to our Pending Acquisition of Dana's Off-Highway Business (the "Acquisition") The Acquisition may not be completed in a timely manner or at all, and the Purchase Agreement may be terminated in accordance with its terms. The Acquisition is subject to certain customary closing conditions, including (a) the receipt of specified consents, clearances, authorizations and approvals from governmental entities, (b) the absence of any order, injunction, or other judgment or law that makes illegal or prohibits the closing of the Acquisition (the "Closing") and (c) subject to certain exceptions, the accuracy of the representations and warranties of, and compliance with covenants by, each of the parties to the Purchase Agreement. These conditions may not be satisfied or waived in a timely manner or at all, and, accordingly, the Acquisition may be delayed or may not be completed. In addition, either we or Dana may terminate the Purchase Agreement based on the customary termination rights for each party included therein. In addition, we will be required to pay Dana a termination fee of $120 million if the termination is due to the failure of the transactions contemplated by the Purchase Agreement to be completed by a specified outside date as a result of failure to obtain required approvals or clearances under, or as a result of an injunction or order relating to, competition and foreign investment laws. Failure to complete the Acquisition could negatively impact the price of shares of our common stock, as well as our business and results of operations. If the Acquisition is not completed for any reason, our business and results of operations may be adversely affected and, without realizing any of the benefits of having completed the Acquisition, we would be subject to a number of risks, including: we may experience negative reactions from the financial markets, including negative impacts on the market price of our common stock; we may experience negative reactions from customers, suppliers, and other third parties with whom we do business, which in turn could result in a decline in our market share or negatively impact our ability to execute our strategic initiatives; we may experience negative reactions from employees; we will still be required to pay certain significant costs relating to the Acquisition, such as fees to our financial, legal and accounting advisors; and 43 we will have expended time and resources that could otherwise have been spent on our existing business and the pursuit of other opportunities that could have been beneficial to us. Any of the above could negatively impact our ongoing business and results of operations. In addition, if the Purchase Agreement is terminated under certain specified circumstances, we may be required to pay Dana a termination fee as discussed above. We may fail to obtain financing intended to fund the Acquisition. As previously disclosed, we expect to replace the Bridge Facility prior to the Closing with permanent financing, which may include the issuance of debt securities. Our ability to obtain any such new debt financing will depend on, among other factors, prevailing market conditions and other factors beyond our control. We cannot assure you that we will be able to obtain new debt financing on terms acceptable to us, and any such failure could materially adversely affect our business, results of operations and financial condition. The consummation of the Acquisition is not conditioned upon the receipt of any financing. Uncertainties associated with the Acquisition may cause a loss of our and Danas management personnel and other key employees, which could adversely affect our business and operations. We depend on the experience and industry knowledge of our officers and other key employees to execute our business plans. The success of the combined business and operations after the Closing will depend, in part, on our ability to retain key management personnel and other key employees. Our and Danas current and prospective employees may experience uncertainty about their roles within Allison following the Acquisition or other concerns regarding the timing and completion of the Acquisition or the operations of Allison following the Acquisition, any of which may have an adverse effect on our ability to retain or attract key management and other key personnel, which could materially adversely affect our business, results of operations and financial condition. No assurance can be given that, following the Acquisition, we will be able to retain or attract our and Danas key management personnel and other key employees to the same extent that we and Dana have previously been able to retain or attract personnel. Our and Danas business relationships may be subject to disruption due to uncertainty associated with the Acquisition, which could have a material effect on our business, results of operations and financial condition following the Acquisition. Parties with whom we or Dana do business may experience uncertainty associated with the Acquisition, including with respect to current or future business relationships with us or Dana following the Acquisition. Our and Danas business relationships may be subject to disruption as customers, suppliers, and other third parties with whom we or Dana do business may attempt to delay or defer entering into new business relationships with us or Dana, negotiate changes in their existing business relationships with us or Dana or consider entering into business relationships with parties other than us or Dana. These disruptions could have a material and adverse effect on our business, results of operations and financial condition, regardless of whether the Acquisition is completed, as well as a material and adverse effect on our ability to realize the expected opportunities, cost savings, operating synergies and other benefits of the Acquisition. The adverse impacts could be exacerbated by a delay in completion of the Acquisition or termination of the Purchase Agreement. We expect to incur significant costs in connection with the Acquisition and integration of Dana's off-highway business (the "Business"). We have incurred and expect to continue to incur costs associated with completing the Acquisition and integrating the Business. These costs have been, and will continue to be, substantial and include, among others, fees paid to financial, legal and accounting advisors. Many of these costs will be borne by us even if the Acquisition is not completed. 44 We have incurred and will also continue to incur costs related to formulating and implementing integration plans, including facilities, systems and service contract consolidation costs and employmentrelated costs. We will continue to assess the magnitude of these costs, and additional unanticipated costs may be incurred in connection with the Acquisition and the integration of the Business. The costs described above, as well as other unanticipated costs and expenses, could adversely affect our business, results of operations and financial condition. Litigation relating to the Acquisition, if any, could result in an injunction preventing the completion of the Acquisition and/or substantial costs to us. Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into acquisition, merger or other business combination agreements like the Purchase Agreement. Even if such a lawsuit is without merit, defending against these claims can result in substantial costs and divert management time and resources. Any adverse judgment in such a lawsuit could result in monetary damages, which could have a negative impact on our results of operations and financial condition. Lawsuits that may be brought against us, Dana, or our or their directors could also seek, among other things, injunctive relief or other equitable relief, including a request to enjoin the parties from completing the Acquisition. One of the conditions to the closing of the Acquisition is the absence of any order, injunction, or other judgment or law that makes illegal or prohibits the Closing. Consequently, if a plaintiff is successful in obtaining an injunction prohibiting completion of the Acquisition, that injunction may delay or prevent the Acquisition from being completed within the expected timeframe or at all. The failure to integrate the Business and its operations with ours successfully in the expected time frame may adversely affect our results of operations and financial condition. Following the completion of the Acquisition, the Business and its operations may not be integrated successfully with ours. It is possible that the integration process could result in the loss of our or Danas key employees, the loss of customers, suppliers, service providers or other business counterparties, the disruption of our ongoing businesses, inconsistencies in standards, controls, procedures and policies, potential unknown liabilities and unforeseen expenses, delays, or regulatory conditions associated with and following completion of the Acquisition, higherthanexpected integration costs and an overall postClosing integration process that takes longer than originally anticipated. In addition, the attention of our management team and our resources may be focused on the integration process, which may harm our day-to-day business operations or prevent us from pursuing other opportunities that may be beneficial. We may fail to realize all of the anticipated benefits from the integration of the Business and its operations after the Acquisition. The success of the Acquisition will depend, in part, on our ability to achieve the expected opportunities, cost savings, operating synergies and other benefits from integrating the Business. However, the anticipated benefits of the Acquisition may not be realized fully or at all, may take longer to realize than expected, or may result in other adverse effects that we do not currently foresee. In addition, the estimates and assumptions that we and Dana have made when evaluating the anticipated benefits from the Acquisition may not be accurate, and there could be potential unknown liabilities and unforeseen expenses associated with the Acquisition that could adversely impact us. 45 Our future results following the Acquisition may suffer if we do not effectively manage our expanded operations. Following the Acquisition, the size and complexity of our businesses and operations will increase significantly. Our future success will depend, in part, upon our ability to manage the expanded business. There can be no assurances that the combined businesses and operations will be successful or that we will realize the expected operating synergies, cost savings or other benefits currently anticipated from the Acquisition.
