General	Note 1: General The accompanying unaudited condensed consolidated financial statements of Modine Manufacturing Company (“Modine” or the “Company”) were prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10- 01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes necessary for a comprehensive presentation of financial position, results of operations and cash flows required by GAAP for complete financial statements. The financial statements include all normal recurring adjustments that are, in the opinion of management, necessary for a fair statement of results for the interim periods. Results for the first six months of fiscal 2025 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the consolidated financial statements and related notes in Modine’s Annual Report on Form 10-K for the year ended March 31, 2024. Supplier finance programs The Company facilitates a voluntary supplier finance program through a financial institution that allows certain suppliers in the U.S. and Europe to request early payment for invoices, at a discount, from the financial institution. The Company or the financial institution may terminate the supplier finance program upon days’ notice. The Company’s obligations to its suppliers, including amounts due and payment terms, are consistent, irrespective of whether a supplier participates in the program. The Company is not party to the arrangements between the participating suppliers and the financial institution. Under this program, the Company confirms the validity of supplier invoices to the financial institution and remits payments to it based on the original payment terms, which typically range from days. The outstanding obligations under this program, included within New accounting guidance Segment reporting disclosures In November 2023, the Financial Accounting Standards Board issued new disclosure guidance for reportable segments. The new guidance will require disclosure of significant segment expenses, which are expenses that are (i) significant to the segment, (ii) regularly provided to the chief operating decision maker (“CODM”) and (iii) included in the reported measure of segment profit or loss. In addition, the new guidance will require companies to disclose the title and position of their CODM and expand interim disclosures to include the majority of the annual segment disclosures. The definition of and method for determining reportable segments is unchanged. The new disclosure requirements will become effective for the Company’s fiscal 2025 annual financial statements. The Company is currently evaluating the new disclosures, but does not expect the guidance will have a material impact on its consolidated financial statements.

Fair Value Measurement	Note 4: Fair Value Measurements Fair value is defined as the price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. Fair value measurements are classified under the following hierarchy: ● Level 1 – Quoted prices for identical instruments in active markets. ● Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. ● Level 3 – Model-derived valuations in which one or more significant inputs are not observable. When available, the Company uses quoted market prices to determine fair value and classifies such measurements as Level 1. In some cases, where market prices are not available, the Company uses observable market-based inputs to calculate fair value, in which case the measurements are classified as Level 2. If quoted or observable market prices are not available, the Company determines fair value based upon valuation models that use, where possible, market-based data such as interest rates, yield curves or currency rates. These measurements are classified as Level 3. The carrying values of cash, cash equivalents, restricted cash, trade accounts receivable, accounts payable, and short-term debt approximate fair value due to the short-term nature of these instruments. The fair value of the Company’s long-term debt is disclosed in Note 17.

In connection with the plan termination, the Company expects to make additional cash contributions in the range of million during fiscal 2026. The timing and amount of the final cash contribution and settlement charges could materially differ from the Company’s estimates due to the nature and timing of participant settlements, prevailing market and economic conditions, the duration of the termination process, or other factors.

Income Taxes
Income Taxes	Note 9: Income Taxes The Company’s effective tax rate for the three months ended September 30, 2024 and 2023 was 30.1 percent and 21.4 percent, respectively. The Company’s effective tax rate for the six months ended September 30, 2024 and 2023 was 29.2 percent and 23.0 percent, respectively. The effective tax rates for fiscal 2025 are higher than the prior year, primarily due to changes in the mix and amount of foreign and U.S. earnings. In addition, the effective tax rates for the prior-year periods were favorably impacted by the release of a $1.8 million unrecognized tax benefit during the second quarter of fiscal 2024, due to a lapse in statute of limitations. The Company records valuation allowances against its net deferred tax assets to the extent it determines it is more likely than not that such assets will not be realized in the future. Each quarter, the Company evaluates the probability that its deferred tax assets will be realized and determines whether valuation allowances or adjustments thereto are needed. This determination involves judgement and the use of significant estimates and assumptions, including expectations of future taxable income and tax planning strategies. In addition, the Company considers the duration of statutory carryforward periods and historical financial results. At September 30, 2024, valuation allowances against deferred tax assets in the U.S. and in certain foreign jurisdictions totaled $46.3 million and $23.8 million, respectively. The Company will maintain the valuation allowances in each applicable tax jurisdiction until it determines it is more likely than not the deferred tax assets will be realized, thereby eliminating the need for a valuation allowance. Future events or circumstances, such as lower taxable income or unfavorable changes in the financial outlook of the Company’s operations in the U.S. and certain foreign jurisdictions, could necessitate the establishment of further valuation allowances. Accounting policies for interim reporting require the Company to adjust its effective tax rate each quarter to be consistent with its estimated annual effective tax rate. Under this methodology, the Company applies its estimated annual income tax rate to its year-to-date ordinary earnings to derive its income tax provision each quarter. The Company records the tax impacts of certain significant, unusual or infrequently occurring items in the period in which they occur. In addition, the Company excludes the impact of operations anticipated to generate net operating losses for the full fiscal year from the overall effective tax rate calculation and instead records them discretely based upon year-to-date results. The Company does not anticipate a significant change in unrecognized tax benefits during the remainder of fiscal 2025.

In addition, the agreements may require prepayment in the event of certain asset sales. Financial covenants within its credit agreements include a leverage ratio covenant, which requires the Company to limit its consolidated indebtedness, less a portion of its cash balances, both as defined by the credit agreements, to no more than three and one-quarter times consolidated net earnings before interest, taxes, depreciation, amortization, and certain other adjustments (“Adjusted EBITDA”). The Company must also maintain a ratio of Adjusted EBITDA of at least times consolidated interest expense. As of September 30, 2024, the Company was in compliance with its debt covenants.

Risks, Uncertainties, Contingencies and Litigation	Note 18: Risks, Uncertainties, Contingencies and Litigation Environmental The Company has recorded environmental monitoring and remediation accruals related to manufacturing facilities in the U.S., one of which the Company currently owns and operates, and at its former manufacturing facility in the Netherlands. These accruals primarily relate to soil and groundwater contamination at facilities where past operations followed practices and procedures that were considered acceptable under then-existing regulations, or where the Company is a successor to the obligations of prior owners, and current laws and regulations require investigative and/or remedial work to ensure sufficient environmental compliance. In instances where a range of loss can be reasonably estimated for a probable environmental liability, but no amount within the range is a better estimate than any other amount, the Company accrues the minimum of the range. The Company’s accruals for environmental matters totaled 2024, respectively. As additional information becomes available regarding environmental matters, the Company will re-assess the liabilities and revise the estimated accruals, if necessary. While it is possible that the ultimate environmental remediation costs may be in excess of amounts accrued, the Company believes, based upon currently available information, that the ultimate outcome of these matters, individually and in the aggregate, will not have a material adverse effect on its financial position. However, these matters are subject to inherent uncertainties, and unfavorable outcomes could occur, including significant monetary damages. Other litigation In the normal course of business, the Company and its subsidiaries are named as defendants in various lawsuits and enforcement proceedings by private parties, governmental agencies and/or others in which claims are asserted against Modine. The Company believes that any additional loss in excess of amounts already accrued would not have a material effect on the Company’s consolidated balance sheet, results of operations, and cash flows. In addition, management expects that the liabilities which may ultimately result from such lawsuits or proceedings, if any, would not have a material adverse effect on the Company’s financial position.

New Accounting Guidance	New accounting guidance Segment reporting disclosures In November 2023, the Financial Accounting Standards Board issued new disclosure guidance for reportable segments. The new guidance will require disclosure of significant segment expenses, which are expenses that are (i) significant to the segment, (ii) regularly provided to the chief operating decision maker (“CODM”) and (iii) included in the reported measure of segment profit or loss. In addition, the new guidance will require companies to disclose the title and position of their CODM and expand interim disclosures to include the majority of the annual segment disclosures. The definition of and method for determining reportable segments is unchanged. The new disclosure requirements will become effective for the Company’s fiscal 2025 annual financial statements. The Company is currently evaluating the new disclosures, but does not expect the guidance will have a material impact on its consolidated financial statements.
