Summary of Significant Accounting Policies (Policies)	12 Months Ended
Sep. 30, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation – The consolidated financial statements include the accounts of Energizer and its subsidiaries. All significant intercompany transactions are eliminated. Energizer has no material equity method investments, variable interests or non-controlling interests. As a result of the Varta Divestiture, the respective operations of the Divestment Business, including a loss recorded on divestment, have been classified as discontinued operations in the accompanying Consolidated Statements of Earnings and Comprehensive Income and Statements of Cash Flows for fiscal years 2020. There were no operations for the twelve months ended September 30, 2022 and 2021, and no assets or liabilities associated with this business as of September 30, 2022 or 2021. See Note 5 - Divestment for more information on the discontinued operations.
Use of Estimates	Use of Estimates – The preparation of the Company's Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. On an ongoing basis, Energizer evaluates its estimates, including those related to customer promotional programs and incentives, product returns, bad debts, the carrying value of inventories, intangible and other long-lived assets, income taxes, pensions and other postretirement benefits, share-based compensation, contingencies and acquisitions. Actual results could differ materially from those estimates. In regard to ongoing impairment testing of goodwill and indefinite lived intangible assets, significant deterioration in future cash flow projections, changes in discount rates used in discounted cash flow models or changes in other assumptions used in estimating fair values, versus those anticipated at the time of the initial acquisition, as well as subsequent estimated valuations, could result in impairment charges that may materially affect the financial statements in a given year. Refer to Note 12 Goodwill & Intangibles for additional information.
Cash and Cash Equivalents	Cash and Cash Equivalents – Cash and cash equivalents consist of cash on hand and marketable securities with original maturities of three months or less. At September 30, 2022 and 2021, Energizer had $205.3 and $238.9, respectively, in available cash, 73.5% and 94.8% of which was outside of the U.S., respectively. The Company has extensive operations, including a significant manufacturing footprint outside of the U.S. We manage our worldwide cash requirements by reviewing available funds among the many subsidiaries through which we conduct our business and the cost effectiveness with which those funds can be accessed. The repatriation of cash balances from certain of our subsidiaries could have adverse tax consequences or be subject to regulatory capital requirements; however, those balances are generally available without legal restrictions to fund ordinary business operations. Our intention is to reinvest these funds indefinitely. Restricted Cash – The Company defines restricted cash as cash that is legally restricted as to withdrawal or usage. There was no restricted cash at September 30, 2022 and 2021.
Foreign Currency Translations	Foreign Currency Translation – Financial statements of foreign operations where the local currency is the functional currency are translated using end-of-period exchange rates for assets and liabilities and average exchange rates during the period for results of operations. Related translation adjustments are reported as a component within accumulated other comprehensive loss in the equity section of the Consolidated Balance Sheets.Effective July 1, 2018, the financial statements for our Argentina subsidiary are consolidated under the rules governing the translation of financial information in a highly inflationary economy. Under U.S. GAAP, an economy is considered highly inflationary if the cumulative inflation rate for a three year period meets or exceeds 100 percent. The Argentina economy exceeded the three year cumulative inflation rate of 100 percent as of June 2018. If a subsidiary is considered to be in a highly inflationary economy, the financial statements of the subsidiary must be remeasured into the Company’s reporting currency (U.S. dollar) and future exchange gains and losses from the remeasurement of monetary assets and liabilities are reflected in current earnings, rather than exclusively in the equity section of the balance sheet, until such time as the economy is no longer considered highly inflationary.
Financial Instruments and Derivative Securities	Financial Instruments and Derivative Securities – Energizer uses financial instruments, from time to time, in the management of foreign currency, interest rate risk and commodity price risks that are inherent to its business operations. Such instruments are not held or issued for trading purposes. Every derivative instrument (including certain derivative instruments embedded in other contracts) is required to be recorded on the balance sheet at fair value as either an asset or liability. Changes in fair value of recorded derivatives are required to be recognized in earnings unless specific hedge accounting criteria are met. Foreign exchange instruments, including currency forwards, are used primarily to reduce cash transaction exposures and to manage other translation exposures. Foreign exchange instruments used are selected based on their risk reduction attributes, costs and the related market conditions. The Company has designated certain foreign currency contracts as cash flow hedges for accounting purposes as of September 30, 2022 and 2021. The Company has interest rate risk with respect to interest expense on variable rate debt. In December 2020, the Company terminated their previously existing interest rate swap agreements and entered into an interest rate swap (2020 interest rate swap) with an effective date on December 22, 2020, that fixed the variable benchmark component (LIBOR) at an interest rate of 0.95% on variable debt of $550.0. The notional value increased to $700.0 on January 22, 2021, and will stay at that value through December 22, 2024. The notional value will decrease by $100.0 on December 22, 2024 and by $100.0 each year thereafter until its termination date on December 22, 2027. The notional value of the swap was $700.0 at September 30, 2022. Energizer uses raw materials that are subject to price volatility. The Company may use hedging instruments to reduce exposure to variability in cash flows associated with future purchases of commodities. At September 30, 2022 and 2021, the Company had derivative contracts for the future purchases of zinc.
Cash Flow Presentation	Cash Flow Presentation – The Consolidated Statements of Cash Flows are prepared using the indirect method, which reconciles net (loss)/earnings to cash flow from operating activities. The reconciliation adjustments include the removal of timing differences between the occurrence of operating receipts and payments and their recognition in net (loss)/earnings. The adjustments also remove cash flows arising from investing and financing activities, which are presented separately from operating activities. Cash flows from foreign currency transactions and operations are translated at an average exchange rate for the period. Cash flows from hedging activities are included in the same category as the items being hedged, which is primarily operating activities. Cash payments related to income taxes are classified as operating activities.
Trade Receivables, net	Trade Receivables, net – Trade receivables are stated at their net realizable value. The allowance for trade promotions reflects management's estimate of the amount of trade promotions that customers will take as an invoice reduction, rather than receiving cash payments for the trade allowances earned. See additional discussion on the trade allowances in the revenue recognition discussion further in this note. The allowance for doubtful accounts reflects the Company's best estimate of probable losses inherent in the receivables portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available information. Receivables that the Company has factored at September 30, 2022 and 2021 are excluded from the Trade receivables, net balance. Bad debt expense is included in Selling, general and administrative expense (SG&A) in the Consolidated Statements of Earnings and Comprehensive Income.
Inventories	Inventories – Inventories are valued at the lower of cost and net realizable value, with cost generally being determined using average cost or the first-in, first-out (FIFO) method. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company records a reserve for excess and obsolete inventory based upon the historical usage rates, sales patterns of its products and specifically-identified obsolete inventory.
Capitalized Software Costs	Capitalized Software Costs – Capitalized software costs are included in Other assets. These costs are amortized using the straight-line method over periods of related benefit ranging from three to seven years. Expenditures related to capitalized software are included in the Capital expenditures caption in the Consolidated Statements of Cash Flows.
Property, Plant and Equipment, net	Property, Plant and Equipment, net – Property, plant and equipment, net is stated at historical costs. Expenditures for new facilities and expenditures that substantially increase the useful life of property, including interest during construction, are capitalized and reported in the Capital expenditures caption in the Consolidated Statements of Cash Flows. Maintenance, repairs and minor renewals are expensed as incurred. When property is retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts, and gains or losses on the disposition are reflected in earnings. Property, plant and equipment, net held under finance leases are amortized on a straight-line bases over the shorter of the lease term or estimated useful life of the asset and such amortization is included in depreciation expense. Depreciation is generally provided on the straight-line basis by charges to pre-tax earnings at rates based on estimated useful lives. Estimated useful lives range from two to twenty-five years for machinery and equipment and three to thirty years for buildings and building improvements. Depreciation expense in 2022, 2021, and 2020 was $53.1, $53.7, and $63.2, respectively, including accelerated depreciation charges of $3.0, $4.7 and $15.9 in 2022, 2021, and 2020, respectively, primarily related to the IT integration assets and certain manufacturing assets including property, plant and equipment located at facilities that are being consolidated as part of the integration of the Battery and Auto Care Acquisitions. Estimated useful lives are periodically reviewed and, when appropriate, changes are made prospectively. When certain events or changes in operating conditions occur, asset lives may be adjusted and an impairment assessment may be performed on the recoverability of the carrying amounts.
Acquisitions	Acquisitions – Energizer accounts for the acquisition of a business using the acquisition method of accounting and allocates the cost of an acquired business to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess value of the cost of an acquired business over the fair value of the assets acquired and liabilities assumed is recognized as goodwill. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to assets acquired and liabilities assumed with the corresponding offset to goodwill. During fiscal 2021, Energizer used variations of the income approach in determining the fair value of the amortizable intangible assets acquired as part of an acquisition to acquire a company that specializes in developing formulations for cleaning tasks. The Company utilized multi-period excess earnings methods for determining the fair value of the proprietary technology and customer relationships acquired. Our determination of the fair value of these assets involved the use of significant estimates and assumptions related to the revenue growth rates and discount rates. Our determination of the fair value of customer relationships also involved assumptions related to customer attrition rates. Energizer believes that the fair value assigned to the assets acquired and liabilities assumed in the acquisition noted above are based on reasonable assumptions and estimates that marketplace participants would use. However, our assumptions are inherently risky and actual results could differ from those estimates. Adverse changes in the judgments, assumptions and estimates used in future measurements of fair value, including discount rates or future operating results and related cash flow projections, could result in an impairment of goodwill or intangible assets that would require a non-cash charge to the consolidated statements of operations and may have a material effect on our financial condition and operating results.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets – Goodwill and indefinite-lived intangibles are not amortized, but are evaluated annually for impairment as part of the Company's annual business planning cycle in the fourth fiscal quarter, or when indicators of a potential impairment are present. Intangible assets with finite lives are amortized on a straight-line basis over expected lives. Such intangibles are also evaluated for impairment including ongoing monitoring of potential impairment indicators. During the fiscal year 2022 annual impairment analysis during the fourth quarter, the Company identified indefinite lived trade name impairments for Armor All, STP, and Rayovac of $370.4, $26.3, and $127.8, respectively. The Company also identified a goodwill impairment for the Auto Care International reporting unit of $17.4. Refer to Note 12 - Goodwill and Intangible Assets for additional information. Impairment of Long-Lived Assets – Energizer reviews long-lived assets, other than goodwill and other intangible assets for impairment, when events or changes in business circumstances indicate that the remaining useful life may warrant revision or that the carrying amount of the long-lived asset may not be fully recoverable. Energizer performs undiscounted cash flow analysis to determine if impairment exists. If impairment is determined to exist, any related impairment loss is calculated based on estimated fair value. Impairment losses on assets to be disposed of, if any, are based on the estimated proceeds to be received, less cost of disposal.
Revenue Recognition	Revenue Recognition – The Company measures revenue as the amount of consideration for which it expects to be entitled in exchange for transferring goods. Net sales reflect the transaction prices for contracts, which include units shipped at selling list prices reduced by variable consideration as determined by the terms of each individual contract. Discounts are offered to customers for early payment and an estimate of the discount is recorded as a reduction of net sales in the same period as the sale. Our standard sales terms generally include payments within 30 to 60 days and are final with returns or exchanges not permitted unless a special exception is made. Our Auto Care channel terms are longer, in some cases up to 365 days, in which case we use our Trade Receivables factoring program for more timely collection. Reserves are established based on historical data and recorded in cases where the right of return does exist for a particular sale. The Company does not offer warranties on products. Energizer offers a variety of programs, primarily to its retail customers, designed to promote sales of its products. Such programs require periodic payments and allowances based on estimated results of specific programs and are recorded as a reduction to net sales. Methodologies for determining these provisions are dependent on specific customer pricing and promotional practices, which range from contractually fixed percentage price reductions to reimbursement based on actual occurrence or performance. Where applicable, future reimbursements are estimated based on a combination of historical patterns and future expectations regarding specific in-market product performance. Energizer accrues, at the time of sale, the estimated total payments and allowances associated with each transaction. Customers redeem trade promotions in the form of payments from the accrued trade allowances or invoice credits against trade receivables. Additionally, Energizer offers programs directly to consumers to promote the sale of its products. Energizer continually assesses the adequacy of accruals for customer and consumer promotional program costs not yet paid. To the extent total program payments differ from estimates, adjustments may be necessary. Historically, these adjustments have not been material. The Company’s contracts with customers do not have significant financing components or non-cash consideration and the Company does not have unbilled revenue or significant amounts of prepayments from customers. Revenue is recorded net of the taxes we collect on behalf of governmental authorities which are generally included in the price to the customer. Shipping and handling activities are accounted for as contract fulfillment costs and recorded in Cost of products sold.
Advertising and Sales Promotion Costs	Advertising and Sales Promotion Costs – The Company advertises and promotes its products through national and regional media and expenses such activities as incurred.
Research and Development Costs	Research and Development Costs - The Company expenses research and development costs as incurred.
Income Taxes	Income Taxes – Our annual effective income tax rate is determined based on our income, statutory tax rates and the tax impacts of items treated differently for tax purposes than for financial reporting purposes. Tax law requires certain items be included in the tax return at different times than the items are reflected in the financial statements. Some of these differences are permanent, such as expenses that are not deductible in our tax return, and some differences are temporary, reversing over time, such as depreciation expense. These temporary differences create deferred tax assets and liabilities. The Company estimates income taxes and the effective income tax rate in each jurisdiction that it operates. This involves estimating taxable earnings, specific taxable and deductible items, the likelihood of generating sufficient future taxable income to utilize deferred tax assets, the portion of the income of foreign subsidiaries that is expected to be remitted to the U.S. and be taxable and possible exposures related to future tax audits. Deferred tax assets are evaluated on a subsidiary by subsidiary basis to ensure that the asset will be realized. Valuation allowances are established when the realization is not deemed to be more likely than not. Future performance is monitored, and when objectively measurable operating trends change, adjustments are made to the valuation allowances accordingly. To the extent the estimates described above change, adjustments to income taxes are made in the period in which the estimate is changed. In determining whether a valuation allowance against the net deferred tax assets are warranted, the Company assesses all available positive and negative evidence such as prior earnings history, expected future earnings, carry-back and carry-forward periods and the feasibility of ongoing tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. After the evaluation of all available positive and negative evidence, the conclusion was that it is more likely than not that the Company will generate enough future taxable income to realize the U.S. net deferred tax asset on its balance sheet as of September 30, 2022. The Company will continue to regularly assess the potential for realization of net deferred tax assets in future periods. Changes in future earnings projections, among other factors, may result in a valuation allowance against some or all of the net deferred tax assets, which may materially impact income tax expense in the period if it is determined that these factors have changed. The Company operates in multiple jurisdictions with complex tax and regulatory environments, which are subject to differing interpretations by the taxpayer and the taxing authorities. At times, the Company may take positions that management believes are supportable, but are potentially subject to successful challenges by the appropriate taxing authority. The Company evaluates its tax positions and establishes liabilities in accordance with guidance governing accounting for uncertainty in income taxes. The Company reviews these tax uncertainties in light of the changing facts and circumstances, such as the progress of tax audits, and adjusts them accordingly. The Company's policy on accounting for tax on the global intangible low-taxed income (GILTI) is to treat the taxes due as a period expense when incurred. In general, it is our practice and intention to permanently reinvest the earnings of our foreign subsidiaries and repatriate earnings only when the tax impact is zero or very minimal. No provision has been provided for taxes that would result upon repatriation of our foreign investments to the United States. We intend to reinvest these earnings indefinitely in our foreign subsidiaries to fund local operations, fund strategic growth objectives, and fund capital projects. See Note 7, Income Taxes, of the Notes to Consolidated Financial Statements for further discussion.
Share-Based Payments	Share-Based Payments – The Company grants restricted stock equivalents, which generally vest over two to four years. Stock compensation expense is measured at the grant date based on the estimated fair value of the award and is recognized on a straight-line basis over the full restriction period of the award, with forfeitures recognized as they occur.
Estimated Fair Value of Financial Instruments	Estimated Fair Values of Financial Instruments – Certain financial instruments are required to be recorded at the estimated fair value. Changes in assumptions or estimation methods could affect the fair value estimates; however, we do not believe any such changes would have a material impact on our financial condition, results of operations or cash flows. Other financial instruments including cash and cash equivalents, restricted cash, and short-term borrowings, including notes payable, are recorded at cost, which approximates estimated fair value. Reclassifications - Certain reclassifications have been made to the prior year financial statements to conform to the current presentation, including the recast of our segment related disclosures to align with our new reportable segments as of October 1, 2021. Refer to Note 10, Segments, for additional information.
Recently Accounting Pronouncements	Recently Issued Accounting Pronouncements – In December 2019, the FASB issued ASU 2019-12 Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendment simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740 and amends existing guidance to improve consistent application. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020. The Company adopted this standard as of October 1, 2021 and the adoption of this standard did not have a material impact on the Company's consolidated financial statements.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Sep. 30, 2022

Basis of Presentation – The consolidated financial statements include the accounts of Energizer and its subsidiaries. All significant intercompany transactions are eliminated. Energizer has no material equity method investments, variable interests or non-controlling interests.

As a result of the Varta Divestiture, the respective operations of the Divestment Business, including a loss recorded on divestment, have been classified as discontinued operations in the accompanying Consolidated Statements of Earnings and Comprehensive Income and Statements of Cash Flows for fiscal years 2020. There were no operations for the twelve months ended September 30, 2022 and 2021, and no assets or liabilities associated with this business as of September 30, 2022 or 2021. See Note 5 - Divestment for more information on the discontinued operations.

Use of Estimates

Use of Estimates – The preparation of the Company's Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. On an ongoing basis, Energizer evaluates its estimates, including those related to customer promotional programs and incentives, product returns, bad debts, the carrying value of inventories, intangible and other long-lived assets, income taxes, pensions and other postretirement benefits, share-based compensation, contingencies and acquisitions. Actual results could differ materially from those estimates. In regard to ongoing impairment testing of goodwill and indefinite lived intangible assets, significant deterioration in future cash flow projections, changes in discount rates used in discounted cash flow models or changes in other assumptions used in estimating fair values, versus those anticipated at the time of the initial acquisition, as well as subsequent estimated valuations, could result in impairment charges that may materially affect the financial statements in a given year. Refer to Note 12 Goodwill & Intangibles for additional information.

Cash and Cash Equivalents

Cash and Cash Equivalents – Cash and cash equivalents consist of cash on hand and marketable securities with original maturities of three months or less. At September 30, 2022 and 2021, Energizer had $205.3 and $238.9, respectively, in available cash, 73.5% and 94.8% of which was outside of the U.S., respectively. The Company has extensive operations, including a significant manufacturing footprint outside of the U.S. We manage our worldwide cash requirements by reviewing available funds among the many subsidiaries through which we conduct our business and the cost effectiveness with which those funds can be accessed. The repatriation of cash balances from certain of our subsidiaries could have adverse tax consequences or be subject to regulatory capital requirements; however, those balances are generally available without legal restrictions to fund ordinary business operations. Our intention is to reinvest these funds indefinitely.

Restricted Cash – The Company defines restricted cash as cash that is legally restricted as to withdrawal or usage. There was no restricted cash at September 30, 2022 and 2021.

Foreign Currency Translations

Foreign Currency Translation – Financial statements of foreign operations where the local currency is the functional currency are translated using end-of-period exchange rates for assets and liabilities and average exchange rates during the period for results of operations. Related translation adjustments are reported as a component within accumulated other comprehensive loss in the equity section of the Consolidated Balance Sheets.Effective July 1, 2018, the financial statements for our Argentina subsidiary are consolidated under the rules governing the translation of financial information in a highly inflationary economy. Under U.S. GAAP, an economy is considered highly inflationary if the cumulative inflation rate for a three year period meets or exceeds 100 percent. The Argentina economy exceeded the three year cumulative inflation rate of 100 percent as of June 2018. If a subsidiary is considered to be in a highly inflationary economy, the financial statements of the subsidiary must be remeasured into the Company’s reporting currency (U.S. dollar) and future exchange gains and losses from the remeasurement of monetary assets and liabilities are reflected in current earnings, rather than exclusively in the equity section of the balance sheet, until such time as the economy is no longer considered highly inflationary.

Financial Instruments and Derivative Securities

Financial Instruments and Derivative Securities – Energizer uses financial instruments, from time to time, in the management of foreign currency, interest rate risk and commodity price risks that are inherent to its business operations. Such instruments are not held or issued for trading purposes. Every derivative instrument (including certain derivative instruments embedded in other contracts) is required to be recorded on the balance sheet at fair value as either an asset or liability. Changes in fair value of recorded derivatives are required to be recognized in earnings unless specific hedge accounting criteria are met.

Foreign exchange instruments, including currency forwards, are used primarily to reduce cash transaction exposures and to manage other translation exposures. Foreign exchange instruments used are selected based on their risk reduction attributes, costs and the related market conditions. The Company has designated certain foreign currency contracts as cash flow hedges for accounting purposes as of September 30, 2022 and 2021.

The Company has interest rate risk with respect to interest expense on variable rate debt. In December 2020, the Company terminated their previously existing interest rate swap agreements and entered into an interest rate swap (2020 interest rate swap) with an effective date on December 22, 2020, that fixed the variable benchmark component (LIBOR) at an interest rate of 0.95% on variable debt of $550.0. The notional value increased to $700.0 on January 22, 2021, and will stay at that value through December 22, 2024. The notional value will decrease by $100.0 on December 22, 2024 and by $100.0 each year thereafter until its termination date on December 22, 2027. The notional value of the swap was $700.0 at September 30, 2022.

Energizer uses raw materials that are subject to price volatility. The Company may use hedging instruments to reduce exposure to variability in cash flows associated with future purchases of commodities. At September 30, 2022 and 2021, the Company had derivative contracts for the future purchases of zinc.

Cash Flow Presentation

Cash Flow Presentation – The Consolidated Statements of Cash Flows are prepared using the indirect method, which reconciles net (loss)/earnings to cash flow from operating activities. The reconciliation adjustments include the removal of timing differences between the occurrence of operating receipts and payments and their recognition in net (loss)/earnings. The adjustments also remove cash flows arising from investing and financing activities, which are presented separately from operating activities. Cash flows from foreign currency transactions and operations are translated at an average exchange rate for the period. Cash flows from hedging activities are included in the same category as the items being hedged, which is primarily operating activities. Cash payments related to income taxes are classified as operating activities.

Trade Receivables, net

Trade Receivables, net – Trade receivables are stated at their net realizable value. The allowance for trade promotions reflects management's estimate of the amount of trade promotions that customers will take as an invoice reduction, rather than receiving cash payments for the trade allowances earned. See additional discussion on the trade allowances in the revenue recognition discussion further in this note. The allowance for doubtful accounts reflects the Company's best estimate of probable losses inherent in the receivables portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available information. Receivables that the Company has factored at September 30, 2022 and 2021 are excluded from the Trade receivables, net balance. Bad debt expense is included in Selling, general and administrative expense (SG&A) in the Consolidated Statements of Earnings and Comprehensive Income.

Inventories

Inventories – Inventories are valued at the lower of cost and net realizable value, with cost generally being determined using average cost or the first-in, first-out (FIFO) method. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company records a reserve for excess and obsolete inventory based upon the historical usage rates, sales patterns of its products and specifically-identified obsolete inventory.

Capitalized Software Costs

Capitalized Software Costs – Capitalized software costs are included in Other assets. These costs are amortized using the straight-line method over periods of related benefit ranging from three to seven years. Expenditures related to capitalized software are included in the Capital expenditures caption in the Consolidated Statements of Cash Flows.

Property, Plant and Equipment, net

Property, Plant and Equipment, net – Property, plant and equipment, net is stated at historical costs. Expenditures for new facilities and expenditures that substantially increase the useful life of property, including interest during construction, are capitalized and reported in the Capital expenditures caption in the Consolidated Statements of Cash Flows. Maintenance, repairs and minor renewals are expensed as incurred. When property is retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts, and gains or losses on the disposition are reflected in earnings.

Property, plant and equipment, net held under finance leases are amortized on a straight-line bases over the shorter of the lease term or estimated useful life of the asset and such amortization is included in depreciation expense.

Depreciation is generally provided on the straight-line basis by charges to pre-tax earnings at rates based on estimated useful lives. Estimated useful lives range from two to twenty-five years for machinery and equipment and three to thirty years for buildings and building improvements. Depreciation expense in 2022, 2021, and 2020 was $53.1, $53.7, and $63.2, respectively, including accelerated depreciation charges of $3.0, $4.7 and $15.9 in 2022, 2021, and 2020, respectively, primarily related to the IT integration assets and certain manufacturing assets including property, plant and equipment located at facilities that are being consolidated as part of the integration of the Battery and Auto Care Acquisitions.

Estimated useful lives are periodically reviewed and, when appropriate, changes are made prospectively. When certain events or changes in operating conditions occur, asset lives may be adjusted and an impairment assessment may be performed on the recoverability of the carrying amounts.

Acquisitions

Acquisitions – Energizer accounts for the acquisition of a business using the acquisition method of accounting and allocates the cost of an acquired business to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess value of the cost of an acquired business over the fair value of the assets acquired and liabilities assumed is recognized as goodwill. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to assets acquired and liabilities assumed with the corresponding offset to goodwill.

During fiscal 2021, Energizer used variations of the income approach in determining the fair value of the amortizable intangible assets acquired as part of an acquisition to acquire a company that specializes in developing formulations for cleaning tasks. The Company utilized multi-period excess earnings methods for determining the fair value of the proprietary technology and customer relationships acquired. Our determination of the fair value of these assets involved the use of significant estimates and assumptions related to the revenue growth rates and discount rates. Our determination of the fair value of customer relationships also involved assumptions related to customer attrition rates.

Energizer believes that the fair value assigned to the assets acquired and liabilities assumed in the acquisition noted above are based on reasonable assumptions and estimates that marketplace participants would use. However, our assumptions are inherently risky and actual results could differ from those estimates. Adverse changes in the judgments, assumptions and estimates used in future measurements of fair value, including discount rates or future operating results and related cash flow projections, could result in an impairment of goodwill or intangible assets that would require a non-cash charge to the consolidated statements of operations and may have a material effect on our financial condition and operating results.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets – Goodwill and indefinite-lived intangibles are not amortized, but are evaluated annually for impairment as part of the Company's annual business planning cycle in the fourth fiscal quarter, or when indicators of a potential impairment are present. Intangible assets with finite lives are amortized on a straight-line basis over expected lives. Such intangibles are also evaluated for impairment including ongoing monitoring of potential impairment indicators. During the fiscal year 2022 annual impairment analysis during the fourth quarter, the Company identified indefinite lived trade name impairments for Armor All, STP, and Rayovac of $370.4, $26.3, and $127.8, respectively. The Company also identified a goodwill impairment for the Auto Care International reporting unit of $17.4. Refer to Note 12 - Goodwill and Intangible Assets for additional information. Impairment of Long-Lived Assets – Energizer reviews long-lived assets, other than goodwill and other intangible assets for impairment, when events or changes in business circumstances indicate that the remaining useful life may warrant revision or that the carrying amount of the long-lived asset may not be fully recoverable. Energizer performs undiscounted cash flow analysis to determine if impairment exists. If impairment is determined to exist, any related impairment loss is calculated based on estimated fair value. Impairment losses on assets to be disposed of, if any, are based on the estimated proceeds to be received, less cost of disposal.

Revenue Recognition

Revenue Recognition – The Company measures revenue as the amount of consideration for which it expects to be entitled in exchange for transferring goods. Net sales reflect the transaction prices for contracts, which include units shipped at selling list prices reduced by variable consideration as determined by the terms of each individual contract. Discounts are offered to customers for early payment and an estimate of the discount is recorded as a reduction of net sales in the same period as the sale. Our standard sales terms generally include payments within 30 to 60 days and are final with returns or exchanges not permitted unless a special exception is made. Our Auto Care channel terms are longer, in some cases up to 365 days, in which case we use our Trade Receivables factoring program for more timely collection. Reserves are established based on historical

data and recorded in cases where the right of return does exist for a particular sale. The Company does not offer warranties on products.

Energizer offers a variety of programs, primarily to its retail customers, designed to promote sales of its products. Such programs require periodic payments and allowances based on estimated results of specific programs and are recorded as a reduction to net sales. Methodologies for determining these provisions are dependent on specific customer pricing and promotional practices, which range from contractually fixed percentage price reductions to reimbursement based on actual occurrence or performance. Where applicable, future reimbursements are estimated based on a combination of historical patterns and future expectations regarding specific in-market product performance. Energizer accrues, at the time of sale, the estimated total payments and allowances associated with each transaction. Customers redeem trade promotions in the form of payments from the accrued trade allowances or invoice credits against trade receivables. Additionally, Energizer offers programs directly to consumers to promote the sale of its products. Energizer continually assesses the adequacy of accruals for customer and consumer promotional program costs not yet paid. To the extent total program payments differ from estimates, adjustments may be necessary. Historically, these adjustments have not been material.

The Company’s contracts with customers do not have significant financing components or non-cash consideration and the Company does not have unbilled revenue or significant amounts of prepayments from customers. Revenue is recorded net of the taxes we collect on behalf of governmental authorities which are generally included in the price to the customer. Shipping and handling activities are accounted for as contract fulfillment costs and recorded in Cost of products sold.

Income Taxes

Income Taxes – Our annual effective income tax rate is determined based on our income, statutory tax rates and the tax impacts of items treated differently for tax purposes than for financial reporting purposes. Tax law requires certain items be included in the tax return at different times than the items are reflected in the financial statements. Some of these differences are permanent, such as expenses that are not deductible in our tax return, and some differences are temporary, reversing over time, such as depreciation expense. These temporary differences create deferred tax assets and liabilities.

The Company estimates income taxes and the effective income tax rate in each jurisdiction that it operates. This involves estimating taxable earnings, specific taxable and deductible items, the likelihood of generating sufficient future taxable income to utilize deferred tax assets, the portion of the income of foreign subsidiaries that is expected to be remitted to the U.S. and be taxable and possible exposures related to future tax audits. Deferred tax assets are evaluated on a subsidiary by subsidiary basis to ensure that the asset will be realized. Valuation allowances are established when the realization is not deemed to be more likely than not. Future performance is monitored, and when objectively measurable operating trends change, adjustments are made to the valuation allowances accordingly. To the extent the estimates described above change, adjustments to income taxes are made in the period in which the estimate is changed.

In determining whether a valuation allowance against the net deferred tax assets are warranted, the Company assesses all available positive and negative evidence such as prior earnings history, expected future earnings, carry-back and carry-forward periods and the feasibility of ongoing tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. After the evaluation of all available positive and negative evidence, the conclusion was that it is more likely than not that the Company will generate enough future taxable income to realize the U.S. net deferred tax asset on its balance sheet as of September 30, 2022. The Company will continue to regularly assess the potential for realization of net deferred tax assets in future periods. Changes in future earnings projections, among other factors, may result in a valuation allowance against some or all of the net deferred tax assets, which may materially impact income tax expense in the period if it is determined that these factors have changed.

The Company operates in multiple jurisdictions with complex tax and regulatory environments, which are subject to differing interpretations by the taxpayer and the taxing authorities. At times, the Company may take positions that management believes are supportable, but are potentially subject to successful challenges by the appropriate taxing authority. The Company evaluates its tax positions and establishes liabilities in accordance with guidance governing accounting for uncertainty in income taxes. The Company reviews these tax uncertainties in light of the changing facts and circumstances, such as the progress of tax

audits, and adjusts them accordingly. The Company's policy on accounting for tax on the global intangible low-taxed income (GILTI) is to treat the taxes due as a period expense when incurred.

In general, it is our practice and intention to permanently reinvest the earnings of our foreign subsidiaries and repatriate earnings only when the tax impact is zero or very minimal. No provision has been provided for taxes that would result upon repatriation of our foreign investments to the United States. We intend to reinvest these earnings indefinitely in our foreign subsidiaries to fund local operations, fund strategic growth objectives, and fund capital projects. See Note 7, Income Taxes, of the Notes to Consolidated Financial Statements for further discussion.

Share-Based Payments

Share-Based Payments – The Company grants restricted stock equivalents, which generally vest over two to four years. Stock compensation expense is measured at the grant date based on the estimated fair value of the award and is recognized on a straight-line basis over the full restriction period of the award, with forfeitures recognized as they occur.

Estimated Fair Value of Financial Instruments

Estimated Fair Values of Financial Instruments – Certain financial instruments are required to be recorded at the estimated fair value. Changes in assumptions or estimation methods could affect the fair value estimates; however, we do not believe any such changes would have a material impact on our financial condition, results of operations or cash flows. Other financial instruments including cash and cash equivalents, restricted cash, and short-term borrowings, including notes payable, are recorded at cost, which approximates estimated fair value.

Reclassifications - Certain reclassifications have been made to the prior year financial statements to conform to the current presentation, including the recast of our segment related disclosures to align with our new reportable segments as of October 1, 2021. Refer to Note 10, Segments, for additional information.
