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 1. Disposition of Air-cooled Automotive Business On April the Company sold its air-cooled automotive business 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 the business’s 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. The finalization of and payment for the purchase price adjustment for net working capital and certain other items, as defined by the sale agreement, is pending. While the Company does not expect a material adjustment, it is possible that the loss on sale may increase when the purchase price adjustment is finalized. Prior to the disposition, the Company reported the financial results of this business within the Automotive segment. The air-cooled automotive business’s net sales were in fiscal In connection with the sale of the air-cooled automotive business, the Company provided the buyer with a 5-year, 4.0 million euro loan facility. Borrowings under the agreement currently bear interest at 2.5 percent. During the second quarter of fiscal 2022, the Company disbursed 4.0 million euro, or $4.7 million, to the buyer under this facility. As of September 30, 2021, the Company recorded the 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. Disposition of Previously-Closed Facility 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 Commercial and Industrial Solutions (“CIS”) 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. Chief Executive Officer (“CEO”) Transition in Fiscal 2021 In August 2020, Thomas A. Burke stepped down from his position as President and CEO. As a result of Mr. Burke’s departure and in connection with the search for his successor, the Company recorded costs totaling $5.5 million during the second quarter of fiscal 2021. These costs, which were recorded as selling, general and administrative (“SG&A”) expenses at Corporate, primarily consisted of severance and benefit-related expenses based upon the terms of Mr. Burke’s transition and separation agreement and costs directly associated with the CEO search, partially offset by the impact of Mr. Burke’s forfeited stock-based compensation awards.

Assets Held for Sale [Abstract]
Assets Held for Sale	Note 2: Assets Held for Sale Liquid-cooled Automotive Business On November 2, 2020, the Company signed a definitive agreement to sell its liquid-cooled automotive business to Dana Incorporated (“Dana”) On October 25, 2021, the Company announced that it has reached a mutual agreement with Dana to terminate the sale agreement. Both companies have been actively engaged in the regulatory review process in Germany for many months and mutually decided that it is no longer in the best interest of either party to pursue the transaction further. As a result, the Company expects that the liquid-cooled automotive business will no longer meet the requirements to be classified as held for sale during the third quarter of fiscal 2022. The Company expects that, upon reverting back to held and used classification during the third quarter of fiscal 2022, it will measure the asset groups within the modified sale perimeter at the lower of their (i) carrying value, as if held for sale classification had not been met; or (ii) fair value. The long-lived assets within the liquid-cooled automotive business, primarily property, plant and equipment, have been fully impaired while classified as held for sale. Through September 30, 2021, the Company recorded $119.6 million of cumulative asset impairment charges related to these assets. At this time, the Company is unable to quantify or predict any adjustments to the carrying value of the liquid-cooled automotive business's long-lived assets to be recorded during the third quarter of fiscal 2022. At each reporting date while the liquid-cooled automotive business was held for sale, the Company reassessed its fair value less costs to sell. As a result of these evaluations for the first two quarters of fiscal 2022, the Company recorded a total of $8.6 million of non-cash impairment charges related to the Automotive segment’s held for sale assets. These impairment charges reduced the net carrying value of property, plant and equipment additions during each quarter to zero. In addition, in connection with the modification to the sale perimeter in the first quarter of fiscal 2022, the Company determined that certain manufacturing operations no longer met the requirements to be classified as held for sale. As a result of its evaluation, the Company reversed $7.4 million of impairment charges to adjust the long-lived asset groups to their estimated fair value as of June 30, 2021. For purposes of its evaluation, the Company estimated the fair value of the businesses primarily using the income approach, which is a valuation technique that focuses on future cash flows anticipated to be generated by a business. The Company’s determination of fair value involved judgement and the use of significant estimates and assumptions, including assumptions regarding future revenue projections and operating profit margins, risk-adjusted discount rates, business trends and market conditions. The fair value measurements of these businesses are categorized as Level 3 within the fair value hierarchy. Refer to Note 4 for the definition of a Level 3 fair value measurement. Assets and Liabilities Held for Sale As of S , the Company presented the assets and liabilities within the modified sale perimeter of the liquid-cooled automotive business as held for sale on its consolidated balance sheet. As of , the Company presented the assets and liabilities of the liquid- and air-cooled automotive businesses as held for sale.

The $4.7 million increase in contract assets during the first six months of fiscal 2022 primarily resulted from an increase in contracts assets for revenue recognized over time and, to a lesser extent, an increase in capitalized costs related to customer-owned tooling contracts. Contract liabilities, included within other current liabilities in the consolidated balance sheets, consist of payments received in advance of satisfying performance obligations under customer contracts, including contracts for customer-owned tooling. The $1.5 million increase in contract liabilities during the first six months of fiscal 2022 was primarily related to customer contracts for which payment was received in advance of the Company’s satisfaction of performance obligations.

Fair Value Measurements

Fair Value Measurements [Abstract]
Fair Value Measurements	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, short-term investments, trade accounts receivable, accounts payable, and short-term debt approximate fair value due to the short-term nature of these instruments. In addition, the Company assesses the fair value of a disposal group for each reporting period it is held for sale. See Note for additional information regarding assets held for sale. The fair value of the Company’s long-term debt is disclosed in Note . The Company holds investments in deferred compensation trusts to fund obligations under certain non-qualified deferred compensation plans. The Company records the fair value of these investments within other noncurrent assets on its consolidated balance sheets. The Company classifies money market investments held by the trusts within Level 2 of the valuation hierarchy. The Company classifies all other investments held by the trusts within Level 1 of the valuation hierarchy, as it uses quoted market prices to determine the investments’ fair value. The Company’s deferred compensation obligations, which are recorded as other noncurrent liabilities, are recorded at the fair values of the investments held by the trust. At September 30, 2021 and March 31, 2021 , the fair values of the investments and obligations for the Company’s deferred compensation plans each totaled $ million and $ million, respectively

Stock-Based Compensation [Abstract]
Stock-Based Compensation	Note 6: Stock-Based Compensation The Company’s stock-based incentive programs consist of the following: (1) a long-term incentive plan (“LTIP”) for officers and other executives that consists of stock awards, stock options, and performance-based stock awards granted for retention and performance, (2) a discretionary equity program for other management and key employees, and (3) stock awards for non-employee directors. 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 and $1.4 million for the three months ended September 30, 2021 and 2020, respectively. The Company recognized stock-based compensation expense of $3.6 million and $2.1 million for the six months ended September 30, 2021 and 2020, respectively . The fair value of stock-based compensation awards granted during the six months ended September 30, 2021 were as follows: Shares Fair Value Per Award Stock options 0.2 $ 8.98 Restricted stock awards 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 2022. The performance metrics for the cash awards are based upon a target average cash flow return on invested capital and a target average growth in consolidated net earnings before interest, taxes, depreciation, amortization, and certain other adjustments (“Adjusted EBITDA ) at the end of the performance period ending March 31, 2024. In fiscal 2021, the Company granted stock-based awards to officers and other executives during the third quarter of the fiscal year. The Company used the following assumptions in determining fair value for stock options for the six months ended September 30, 2021 Expected life of awards in years 6.1 Risk-free interest rate 1.0 % Expected volatility of the Company’s stock 56.4 % Expected dividend yield on the Company’s stock 0.0 % As of September 30, 2021 Unrecognized Compensation Expense Weighted-Average Remaining Service Period in Years Stock options $ 3.0 3.0 Restricted stock awards 8.2 2.7 Performance stock awards 0.3 0.5 Total $ 11.5 2.7

Income Taxes [Abstract]
Income Taxes	Note 9: Income Taxes The Company’s effective tax rate for the three months ended September 30, 2021 and 2020 was and , respectively. The Company’s effective tax rate for the six months ended September 30, 2021 and 2020 was 68.2 percent and 96.5 percent, respectively . The effective tax rate for the second quarter of fiscal 2022 was negatively impacted by a $1.6 million income tax charge related to a valuation allowance established on deferred tax assets in a foreign jurisdiction. The effective tax rate for the first six months of fiscal 2022, however, was positively impacted by a net $3.2 million income tax benefit related to valuation allowances on deferred tax assets in foreign jurisdictions. Compared to the fiscal 2021 periods, the effective tax rates for the fiscal 2022 periods were negatively impacted by changes in the mix and amount of foreign and U.S. earnings. The effective tax rates for the fiscal 2021 periods were negatively impacted by a $6.6 million income tax charge related to a valuation allowance on deferred tax assets in the U.S. 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 $ million in the first quarter of fiscal 2022. The Company’s analysis included consideration of the perimeter modifications for the liquid-cooled automotive business and the associated reversal of $7.4 million of impairment charges during the first quarter of fiscal 2022; see Note 2 for additional information. 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 Based upon the Company’s analysis as of September 30, 2020, the Company recorded an income tax charge of $ 6.6 As of September and , respectively. These totals exclude the full valuation allowances recorded for net deferred tax assets classified as held for sale. 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 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. The Company excluded the impact of its operations in the U.S. and certain foreign locations from the overall effective tax rate methodology and recorded them discretely based upon year-to-date results because the Company anticipates net operating losses for the full fiscal year in these jurisdictions. The Company does not anticipate a significant change in unrecognized tax benefits during the remainder of fiscal 2022

Goodwill and Intangible Assets [Abstract]
Goodwill and Intangible Assets	Note 14: Goodwill and Intangible Assets Effective July 1, 2021, the Company aligned the data center businesses previously managed by and reported within the CIS segment under the BHVAC segment; see Note 20 for additional information. As a result of this segment realignment, the Company reassigned a total of $32.5 million of goodwill from a reporting unit within the CIS The following table presents a rollforward of the carrying value of goodwill from March 31, 2021 to September 30, 2021. The Company has revised the March 31, 2021 goodwill balances to be comparable with the current segment structure. BHVAC CIS Total Goodwill, March 31 2021 $ 47.0 $ 123.7 $ 170.7 Effect of exchange rate changes (0.5 ) (0.1 ) (0.6 ) Goodwill, September 30 2021 $ 46.5 $ 123.6 $ 170.1 In conjunction with the goodwill reassignment evaluation described above, the Company tested its reporting units for potential impairment and concluded that the estimated fair value of each reporting unit exceeded its respective carrying value. Although the Company concluded goodwill was not impaired, the Company identified that subsequent to the segment realignment, the estimated fair value of the Coils and Coolers reporting unit within the CIS segment exceeds its carrying value by approximately 8.0 percent. As such, there is a heightened risk of a future impairment charge with respect to the $61.0 million of goodwill recorded in this reporting unit as of September 30, 2021. In estimating the fair value of the Coils and Coolers reporting unit, the Company calculated the present value of its anticipated future cash flows using a discounted cash flow model. The most significant estimates and assumptions inherent in the discounted cash flow model are forecasted financial results, the terminal growth rate, and the discount rate. These assumptions are classified as level 3 inputs. Refer to Note 4 for the definition of a Level 3 fair value measurement. The Company utilized its multi-year projections for revenue and operating income margins and considered both historical revenue growth rates and earnings levels as well as its assessment of future market potential and expectations for the future financial performance of the reporting unit. The Company used a discount rate corresponding to its estimated cost of capital, adjusting for country-specific risks based upon the location of the businesses within the reporting unit. While the Company believes the assumptions it used in estimating the Coils and Coolers reporting unit’s fair value were appropriate and resulted in a reasonable estimate of its fair value, future events or circumstances could have a negative effect on its estimated fair value and could trigger an impairment charge. These potential future events or circumstances could include lower than forecasted revenues or earnings, market trends that fall below the Company’s current expectations, actions of key customers, or increases in the discount rate. The Company cannot predict the occurrence of events or changes in circumstances that could adversely affect the reporting unit’s future revenue and operating income margins or increase the discount rate, thereby resulting in an impairment charge which could be material to the Company’s consolidated financial statements. Intangible assets consisted of the following: September 30, 2021 March 31, 2021 Gross Carrying Value Accumulated Amortization Net Intangible Assets Gross Carrying Value Accumulated Amortization Net Intangible Assets Customer relationships $ 62.5 $ (18.7 ) $ 43.8 $ 62.8 $ (16.9 ) $ 45.9 Trade names 51.3 (12.6 ) 38.7 51.5 (11.4 ) 40.1 Acquired technology 23.7 (10.2 ) 13.5 23.9 (9.3 ) 14.6 Total intangible assets $ 137.5 $ (41.5 ) $ 96.0 $ 138.2 $ (37.6 ) $ 100.6 The Company recorded amortization expense of $ million for each of the three months ended September 30, 2021 and 2020.

Long-term debt, including the current portion of long-term debt, matures as follows: Fiscal Year Remainder of 2022 $ 15.1 2023 21.8 2024 21.8 2025 215.2 2026 33.8 2027 & beyond 84.8 Total $ 392.5 The Company maintains a credit agreement with a syndicate of banks that provides for a multi-currency $ 250.0 million revolving credit facility expiring in June 2024. In addition, this credit agreement provides for both U.S. dollar- and euro-denominated term loan facilities and shorter-duration swingline loans. 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, 2021, the weighted-average interest rates for revolving credit facility borrowings and the term loans were each 1.6 percent. Based upon the terms of the credit agreement, the Company classifies borrowings under its revolving credit and swingline facilities as long-term and short-term debt, respectively, on its consolidated balance sheets. At September 30, 2021, the Company’s revolving credit facility borrowings totaled $67.2 million and domestic letters of credit totaled $5.7 million, resulting in available borrowings under the revolving credit facility of $177.1 million. The Company also maintains credit agreements for its foreign subsidiaries. The outstanding short-term borrowings related to these foreign credit agreements totaled $15.2 million at September 30, 2021, of which $15.0 million was classified as held for sale. The $5.0 million of outstanding short-term foreign borrowings at March 31, 2021 were classified as held for sale. See Note 2 for additional information. Provisions in the Company’s credit agreement, Senior Note agreements, and various foreign credit agreements require the Company to maintain compliance with various covenants and include certain cross-default clauses. 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, 2021 and March 31, 2021, 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 $155.1 million and $146.0 million, respectively. The fair value of the Company’s long-term debt is categorized as Level 2 within the fair value hierarchy. Refer to Note 4 for the definition of a Level 2 fair value measurement.

Risks, Uncertainties, Contingencies and Litigation [Abstract]
Risks, Uncertainties, Contingencies and Litigation	Note 18: Risks, Uncertainties, Contingencies and Litigation COVID-19 The COVID-19 pandemic has broadly impacted the global economy and the Company’s key end markets, which were most severely impacted during the first quarter of fiscal 2021. In connection with local government requirements or customer shutdowns, the Company suspended production at many of its manufacturing facilities in March and April 2020. Beginning largely in April 2020 and to mitigate the negative impacts of COVID-19, the Company took actions including, but not limited to, production staffing adjustments, furloughs, shortened work weeks, and temporary salary reductions at all levels of the organization. All of the temporarily-closed facilities reopened in the first or second quarter of fiscal 2021 and have generally returned to more normal production levels. However, since reopening, production at certain of our plants has been negatively affected at times by employee absences due to COVID-19. The Company is continuing to focus on protecting the health and wellbeing of its employees and the communities in which it operates, while also ensuring the continuity of its business operations and timely delivery of quality products and services to its customers. While the Company withdrew most of the cost-saving actions in the third quarter of fiscal 2021 as production returned to more normal levels as markets recovered, it remains focused on controlling operating and administrative expenses. The Company’s consolidated financial statements reflect estimates and assumptions made by management, including assumptions regarding the future impacts of the COVID-19 pandemic, that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. While the Company believes it used appropriate estimates and assumptions to prepare the consolidated financial statements, actual amounts could differ materially, and future events or circumstances could have a potential negative effect on the assumptions used. If the Company, its suppliers, or its customers experience additional shutdowns or other significant business disruptions associated with the COVID-19 pandemic, its ability to conduct business in the manner and on the timelines presently planned could be materially and negatively impacted, which could have a material adverse effect on the Company’s business, financial position, results of operations and cash flows. Environmental The Company has recorded environmental investigation and remediation accruals related to manufacturing facilities in the U.S., one of which the Company currently owns and operates, and a 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 $18.9 million and $16.0 million as of September 30, 2021 and March 31, 2021, respectively. During the first quarter of fiscal 2022, the Company increased its remediation accrual related to a former manufacturing facility in the U.S. by $3.4 million. As additional information becomes available regarding the 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 .
