General [Abstract]
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 -Q and Rule - 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 six months of fiscal 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 -K for the year ended March 2. Disposition of Austrian Air-cooled Automotive Business in Fiscal 2022 On April the Company sold its air-cooled automotive business in Austria to Schmid Metall GmbH. As a result of this transaction, the Company recorded a loss of during the quarter of fiscal which included the write-off of of net actuarial losses related to its pension plan. The Company reported this loss within the loss on sale of assets line on the consolidated statement of operations. Upon transaction closing, of cash within the business transferred to the buyer. In connection with the sale of this business, the Company provided the buyer with a 5-year, €4.0 million loan facility. The buyer began borrowing under this facility during the second quarter of fiscal 2022. At both September 30, 2022 and March 31, 2022, the Company recorded a €4.0 million loan receivable within other noncurrent assets on its consolidated balance sheet because the Company expects to receive the principal repayment more than twelve months from the balance sheet date. Borrowings under the loan facility currently bear interest at 3.7 percent. Liquid-Cooled Automotive Business Held for Sale in Fiscal 2022 The Company previously agreed to sell its liquid-cooled automotive business. During the first quarter of fiscal 2022, the Company and the prospective buyer modified the transaction perimeter to remove certain manufacturing operations. U.S. GAAP requires companies to measure asset groups that revert back to held and used classification at the lower of their (i) carrying value, as if held for sale classification had not been met; or (ii) fair value at the date of the decision not to sell. As a result, the Company evaluated the long-lived assets of these businesses that no longer met the requirements to be classified as held for sale and reversed $7.4 million of previously-recorded impairment charges during the first quarter of fiscal 2022 to adjust the long-lived assets to their estimated fair value. This impairment reversal was partially offset by $8.6 million of impairment charges recorded during the first six months of fiscal 2022 related to other automotive assets held for sale. The Company reported the net $1.2 million impairment charges during the first six months of fiscal 2022 within the impairment charges line on the consolidated statement of operations. The Company and the prospective buyer subsequently terminated the sale agreement during the third quarter of fiscal 2022. As a result, the liquid-cooled automotive business reverted back to held and used classification and the Company remeasured its long-lived assets during the third quarter of fiscal 2022. Disposition of Previously-Closed Facility in Fiscal 2022 During the first quarter of fiscal 2022, the Company signed a definitive agreement to sell a previously-closed manufacturing facility in the U.S. As a result, the Company recorded an impairment charge of $0.3 million within the Climate Solutions segment to write down the property to fair value less costs to sell. During July 2021, the sale was completed and the Company received net cash proceeds of $0.7 million.

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 3: 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, short-term investments, 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 .

The Company calculates compensation expense based upon the fair value of the instruments at the time of grant and subsequently recognizes expense ratably over the respective vesting periods of the stock-based awards. The Company recognized stock-based compensation expense of $2.4 million for each of the three months ended September 30 . The fair value of stock-based compensation awards granted during the six months ended September 30 were as follows: Six months ended September 30 2022 2021 Shares Fair Value Per Award Shares Fair Value Per Award Stock options 0.2 $ 6.97 0.2 $ 8.98 Restricted stock awards 0.4 $ 12.51 0.3 $ 15.97 Unrestricted stock awards - - 0.1 $ 15.93 In lieu of performance-based stock awards, the Company granted performance cash awards to the LTIP participants during the first six months of fiscal 2023.

Income Taxes [Abstract]
Income Taxes	Note 8: Income Taxes The Company’s effective tax rate for the three months ended September 30, 2022 and 2021 was and , respectively. The Company’s effective tax rate for the six months ended September 30, 2022 and 2021 was 22.6 percent and 68.2 percent, respectively. The effective tax rates for fiscal 2023 are lower than the prior year, primarily due to changes in the mix and amount of foreign and U.S. earnings. The effective tax rate for the first six months of fiscal 2022 was favorably impacted by a net million income tax benefit related to valuation allowances on deferred tax assets in foreign jurisdictions. 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. Based upon the Company’s analysis as of June 30, 2021, the Company determined it was more likely than not that the deferred tax assets in a foreign jurisdiction will be realized. As a result, the need for the valuation allowance recorded thereon was eliminated and the Company recorded an income tax benefit of $ 4.8 Based upon the Company’s analysis as of September 30, 2021, the Company determined it was more likely than not that the deferred tax assets in a foreign jurisdiction will not be realized. As a result, the Company recorded an income tax charge of $1.6 million in the second quarter of fiscal 2022. Combined, these fiscal 2022 valuation allowance adjustments resulted in a net income tax benefit of $3.2 million during the first six months of fiscal 2022. At September 30, 2022, valuation allowances against deferred tax assets in the U.S. and in certain foreign jurisdictions totaled and . At present, the Company has recorded a full valuation allowance on its U.S. deferred tax assets. Based upon current and anticipated future earnings in the U.S., the Company believes it is reasonably possible that in late fiscal 2023 or in fiscal 2024, sufficient positive evidence may be available to conclude that a significant portion of the U.S. valuation allowance is not needed. The Company estimates such valuation allowance release, if it were to occur, would result in a decrease to income tax expense of up to $70.0 million in the period recorded. However, if a release of the valuation allowance does occur, the ultimate timing and amount could differ from the Company’s current estimates. Accounting

Borrowings under the revolving credit, swingline and term loan facilities bear interest at a variable rate based upon the applicable reference rate and including a margin percentage dependent upon the Company’s leverage ratio, as described below. At September 30, 2022, the weighted-average interest rates for revolving credit facility borrowings and the term loans were 3.8 and 4.7 percent, respectively .

Under its primary debt agreements in the U.S., the Company has provided liens on substantially all domestic assets. Also, as specified in the credit agreement, the term loans may require prepayments in the event of certain asset sales. In addition, at the time of each incremental borrowing under the revolving credit facility, the Company is required to represent to the lenders that there has been no material adverse effect, as defined in the credit agreement, on its business, property, or results of operations. The leverage ratio covenant 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 The Company estimates the fair value of long-term debt using discounted future cash flows at rates offered to the Company for similar debt instruments of comparable maturities. As of September 30, 2022 and March 31, 2022, the carrying value of the Company’s long-term debt approximated fair value, with the exception of the Senior Notes, which had an aggregate fair value of $130.6 million and $138.9 million, respectively.

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 During the first quarter of fiscal 2023 and 2022, the Company increased its remediation accrual related to a former manufacturing facility in the U.S. by 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 .
