Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K includes “forward-looking statements” as that term is defined in Section 27A of the Securities Act, and Section 21E of the Exchange Act, including statements regarding the Proposed Transaction among Gentherm, Modine and SpinCo. These forward-looking statements generally are identified by the words “believe,” “feel,” “project,” “expect,” “anticipate,” “appear,” “estimate,” “forecast,” “outlook,” “target,” “endeavor,” “seek,” “predict,” “intend,” “suggest,” “strategy,” “plan,” “may,” “could,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” or the negative thereof or variations thereon or similar terminology generally intended to identify forward-looking statements. All statements, other than historical facts, including, but not limited to, statements regarding the expected timing and structure of the Proposed Transaction, the ability of the parties to complete the Proposed Transaction, the expected benefits of the Proposed Transaction, including future financial and operating results, anticipated strategic benefits of the Proposed Transaction, the amount and timing of synergies from the Proposed Transaction, the tax consequences of the Proposed Transaction, the terms and scope of the expected financing in connection with the Proposed Transaction, the aggregate amount of indebtedness of the combined company following the closing of the Proposed Transaction, the combined company’s plans, objectives, expectations and intentions, legal, economic and regulatory conditions, and any assumptions underlying any of the foregoing, are forward-looking statements.

These forward-looking statements are based on Gentherm’s and Modine’s current expectations and are subject to risks and uncertainties surrounding future expectations generally. Actual results could differ materially from those currently anticipated due to a number of risks and uncertainties, many of which are beyond Gentherm’s and Modine’s control. None of Gentherm, Modine, SpinCo or any of their respective directors, executive officers, advisors or representatives make any representation or provide any assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements will actually occur, or if any of them do occur, what impact they will have on the business, results of operations or financial condition of Gentherm, Modine or the combined business. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those indicated or anticipated by such forward-looking statements, including developments that could have a material adverse effect on Gentherm’s and Modine’s businesses and the ability to successfully complete the Proposed Transaction and realize its benefits. The inclusion of such statements should not be regarded as a representation that such plans, estimates or expectations will be achieved. Important factors that could cause actual results to differ materially from such plans, estimates or expectations include, among others, (1) that one or more closing conditions to the Proposed Transaction, including certain regulatory approvals, may not be satisfied or waived, on a timely basis or otherwise, including that a governmental entity may prohibit, delay or refuse to grant approval for the consummation of the Proposed Transaction, may require conditions, limitations or restrictions in connection with such approvals or that the required approval by the shareholders of Gentherm may not be obtained; (2) the risk that the Proposed Transaction may not be completed on the terms or in the time frame expected by Gentherm, Modine and SpinCo, or at all; (3) unexpected costs, charges or expenses resulting from the Proposed Transaction; (4) uncertainty of the expected financial performance of the combined company following completion of the Proposed Transaction; (5) failure to realize the anticipated benefits of the Proposed Transaction, including as a result of delay in completing the Proposed Transaction or integrating the businesses of Gentherm and SpinCo, on the expected timeframe or at all; (6) the ability of the combined company to implement its business strategy; (7) difficulties and delays in the combined

company achieving revenue and cost synergies; (8) inability of the combined company to retain and hire key personnel; (9) the occurrence of any event that could give rise to termination of the Proposed Transaction; (10) the risk that shareholder litigation in connection with the Proposed Transaction or other litigation, settlements or investigations may affect the timing or occurrence of the Proposed Transaction or result in significant costs of defense, indemnification and liability; (11) evolving legal, regulatory and tax regimes; (12) changes in general economic and/or industry specific conditions or any volatility resulting from the imposition of and changing policies, including those policies with respect to tariffs; (13) actions by third parties, including government agencies; (14) the risk that the anticipated tax treatment of the Proposed Transaction is not obtained; (15) the risk of greater than expected difficulty in separating the business of SpinCo from the other businesses of Modine; (16) risks related to the disruption of management time from ongoing business operations due to the pendency of the Proposed Transaction, or other effects of the pendency of the Proposed Transaction on the relationship of any of the parties to the Proposed Transaction with their employees, customers, suppliers, or other counterparties; and (17) other risk factors detailed from time to time in Gentherm’s and Modine’s reports filed with the SEC, including Gentherm’s and Modine’s annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and other documents filed with the SEC, including documents that will be filed with the SEC in connection with the Proposed Transaction. The foregoing list of important factors is not exclusive.

Any forward-looking statements speak only as of the date of this Current Report on Form 8-K. None of Gentherm, Modine or SpinCo undertakes, and each party expressly disclaims, any obligation to update any forward-looking statements, whether as a result of new information or development, future events or otherwise, except as required by law. Readers are cautioned not to place undue reliance on any of these forward-looking statements.
