Accounting Policies [Abstract]
Business and Basis of Presentation	1 . Business BrightView Holdings, Inc. (the “Company” and, collectively with its consolidated subsidiaries, “BrightView”) provides landscape maintenance and enhancements, landscape development, snow removal and other landscape related services for commercial customers throughout the United States. BrightView is aligned into two reportable segments: Maintenance Services and Development Services. Basis of Presentation These consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim reporting and are unaudited. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments, including normal, recurring accruals that are necessary for a fair presentation of the Company’s operations for the periods presented in conformity with GAAP. All intercompany activity and balances have been eliminated from the consolidated financial statements. The consolidated results of operations for the interim periods presented are not necessarily indicative of results for the full year. The Consolidated Balance Sheet as of September 30, 2024, presented herein, has been derived from the Company’s audited consolidated financial statements as of and for the fiscal year ended September 30, 2024, but does not include all disclosures required by GAAP, for annual financial statements. For a more complete discussion of the Company’s accounting policies and certain other information, refer to the audited consolidated financial statements and the notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended September 30, 2024 , filed with the Securities and Exchange Commission (“SEC”). Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions 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 the reported amounts of revenues and expenses during the period. On an ongoing basis, management reviews its estimates, including those related to allowances for doubtful accounts, revenue recognition, self-insurance reserves, estimates related to the Company’s assessment of goodwill for impairment, useful lives for depreciation and amortization, realizability of deferred tax assets, and litigation based on currently available information. Changes in facts and circumstances may result in revised estimates and actual results may differ from estimates.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	2 . Recent Accounting Pronouncements Reference Rate Reform In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting which provides optional expedients and exceptions for the accounting for contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. In January 2021, the FASB issued ASU 2021-01 to clarify the scope of certain optional expedients for derivatives that are affected by the discounting transition. In December 2022, the FASB issued ASU 2022-06 to defer the sunset date of Topic 848 from December 31, 2022, to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. As of December 31, 2024, the Company was not party to any contracts, hedging relationships, or other transactions affected by reference rate reform. Segment Reporting In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The purpose of the guidance is to enable investors to better understand an entity’s overall performance and assess potential future cash flows. The amendment is effective for fiscal years beginning after December 15, 2023 and interim periods in fiscal years beginning after December 15, 2024. The Company is in the process of evaluating the impact of ASU No. 2023-07 on its consolidated financial statements. Income Taxes In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU expands public entities tax disclosures including improving disclosures surrounding the company's rate reconciliation, cash taxes paid, and disaggregation of income tax expense (or benefit) from continuing operations. The amendment is effective for annual periods beginning after December 15, 2024. The Company is in the process of evaluating the impact of ASU No. 2023-09 on its consolidated financial statements. Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU No. 2024-03, Income Statement (Subtopic 220-40): Expense Disaggregation Disclosures. The ASU enhances disclosure of income statement expense categories to improve transparency and provide financial statement users with more detailed information about the nature, amount, and timing of expenses impacting financial performance. In January 2025, the FASB issued ASU No. 2025-01 to clarify the effective date of the update. The amendment is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. The Company is in the process of evaluating the impact of ASU No. 2024-03 on its consolidated financial statements.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	3 . Revenue The Company’s revenue is generated from Maintenance Services and Development Services. The Company generally recognizes revenue from the sale of services as the services are performed, typically ratably over the term of the contract(s), which the Company believes to be the best measure of progress. The Company recognizes revenues as it transfers control of products and services to its customers. The Company recognizes revenue in an amount reflecting the total consideration it expects to receive from the customer. Revenue is recognized according to the following five step model: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenues when a performance obligation is satisfied. The Company determined that for contracts containing multiple performance obligations, stand-alone selling price is readily determinable for each performance obligation and therefore allocation of the transaction price to multiple performance obligations is not necessary. The transaction price will include estimates of variable consideration, such as returns and provisions for doubtful accounts and sales incentives, to the extent it is probable that a significant reversal of revenue recognized will not occur. In all cases, when a sale is recorded by the Company, no significant uncertainty exists surrounding the purchaser’s obligation to pay. Maintenance Services The Company’s Maintenance Services revenues are generated primarily through landscape maintenance services and snow removal services. Landscape maintenance services that are primarily viewed as non-discretionary, such as lawn care, mowing, gardening, mulching, leaf removal, irrigation and tree care, are provided under recurring annual contracts, which typically range from one to three years in duration and are generally cancellable by the customer with 30-90 days’ notice. Snow removal services are provided on either fixed fee based contracts or per occurrence contracts. Both landscape maintenance services and snow removal services can also include enhancement services that represent supplemental maintenance or improvement services generally provided under contracts of short duration related to specific services. Revenue for landscape maintenance and snow removal services under fixed fee models is recognized over time using an output based method. Additionally, a portion of the Company’s recurring fixed fee landscape maintenance and snow removal services are recorded under the series guidance. The right to invoice practical expedient is generally applied to revenue related to landscape maintenance and snow removal services performed in relation to per occurrence contracts as well as enhancement services. When use of the practical expedient is not appropriate for these contracts, revenue is recognized using a cost-to-cost input method. Fees for contracted landscape maintenance services are typically billed on an equal monthly basis. Fees for fixed fee snow removal services are typically billed on an equal monthly basis during snow season, while fees for time and material or other activity-based snow removal services are typically billed as the services are performed. Fees for enhancement services are typically billed as the services are performed. Development Services Development Services revenues are generated primarily through landscape architecture and development services. These revenues are primarily recognized over time using the cost-to-cost input method, measured by the percentage of cost incurred to date to the estimated total cost for each contract, which we believe to be the best measure of progress. The full amount of anticipated losses on contracts is recorded as soon as such losses can be estimated. These losses are immaterial to current and historical operations. Changes in job performance, job conditions, and estimated profitability, including final contract settlements, may result in revisions to costs and revenue and are recognized in the period in which the revisions are determined. Disaggregation of revenue The following table presents the Company’s reportable segment revenues, disaggregated by revenue type. The Company disaggregates revenue from contracts with customers into major services lines. The Company has determined that disaggregating revenue into these categories depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. As noted in the business segment reporting information in Note 12 “Segments”, the Company’s reportable segments are Maintenance Services and Development Services. Three Months Ended 2024 2023 Landscape Maintenance $ 376.9 $ 402.6 Snow Removal 32.4 39.7 Maintenance Services 409.3 442.3 Development Services 191.8 185.4 Eliminations ( 1.9 ) ( 1.0 ) Net service revenues $ 599.2 $ 626.7 Remaining Performance Obligations Remaining performance obligations represent the estimated revenue expected to be recognized in the future related to performance obligations which are fully or partially unsatisfied at the end of the period. As of December 31, 2024, the estimated future revenues for remaining performance obligations that are part of a contract that has an original expected duration of greater than one year was approximately $ 521.2 . The Company expects to recognize revenue on 61 % of the remaining performance obligations over the next 12 months and an additional 39 % over the 12 months thereafter. Contract Assets and Liabilities When a contract results in revenue being recognized in excess of the amount the Company has invoiced or has the right to invoice to the customer, a contract asset is recognized. Contract assets are transferred to Accounts receivable, net when the rights to the consideration become unconditional. Contract assets are presented as Unbilled revenue on the Consolidated Balance Sheets. There were $ 51.3 of amounts billed and $ 10.5 of additions to our unbilled revenue balance during the three month period ended December 31, 2024. Contract liabilities consist of payments received from customers, or such consideration that is contractually due, in advance of providing the product or performing services such that control has not passed to the customer. Contract liabilities are presented as Deferred revenue on the Consolidated Balance Sheets. Changes in Deferred revenue for the three month period ended December 31, 2024 were as follows: Deferred Balance, September 30, 2024 $ 83.8 Recognition of revenue ( 252.7 ) Deferral of revenue 280.7 Balance, December 31, 2024 $ 111.8 Practical Expedients and Exemptions The Company offers certain interest-free contracts to customers where payments are received over a period not exceeding one year. Additionally, certain Maintenance Services and Development Services customers may pay in advance for services. The Company does not adjust the promised amount of consideration for the effects of these financing components . At contract inception, the period of time between the performance of services and the customer payment is one year or less. As permitted under the practical expedient available under ASU No. 2014-09, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts with variable consideration that is allocated entirely to unsatisfied performance obligations or to a wholly unsatisfied promise accounted for under the series guidance and (iii) contracts for which the Company recognizes revenue at the amount which we have the right to invoice for services performed.

The Credit Agreement consisted of seven-year $ 1,460.0 term loans (“First Lien Term Loans”) and a five-year $ 210.0 revolving credit facility. All amounts outstanding under the Credit Agreement were collateralized by substantially all of the assets of the Company. The Credit Agreement, as amended, provides for: (i) a $ 1,200.0 seven-year term loan (the “Series B Term Loan”) and (ii) a $ 300.0 five-year revolving credit facility (the “Revolving Credit Facility”). The Series B Term Loan matures on April 22, 2029 . An original issue discount of $ 12.0 was incurred when the Series B Term Loan was issued and is being amortized using the effective interest method over the life of the debt, resulting in an effective yield of 3.42 %. There were no debt repayments for the Series B Term Loan for the three months ended December 31, 2024 and 2023. On August 28, 2023, the Company voluntarily repaid $ 450.0 of the amount outstanding under the Company’s Amendment Agreement. On May 28, 2024, the Company entered into Amendment No. 8 to the Credit Agreement (the “Eighth Credit Agreement Amendment”). Under the Eighth Credit Agreement Amendment, the existing Series B Term Loans were amended to bear interest at a rate per annum based on a secured overnight funding rate (“Term SOFR”), plus a margin of 2.50 % or a base rate (“ABR”) plus a margin of 1.50 %, subject to SOFR and ABR floors of 0.50 % and 1.50 %, respectively.

Fair Value Disclosures [Abstract]
Fair Value Measurements and Derivative Instruments	8 . Fair Value Measurements and Derivative Instruments Fair value is defined as the price at which an orderly transaction to sell an asset or to transfer a liability would take place between market participants at the measurement date under current market conditions (that is, an exit price at the measurement date from the perspective of a market participant that holds the asset or owes the liability). Fair Value Hierarchy The following hierarchy for inputs used in measuring fair value should maximize the use of observable inputs and minimize the use of unobservable inputs by requiring that the most observable inputs be used when available: Level 1 Quoted prices in active markets for identical assets or liabilities that are accessible at the measurement dates. Level 2 Significant observable inputs that are used by market participants in pricing the asset or liability based on market data obtained from independent sources. Level 3 Significant unobservable inputs the Company believes market participants would use in pricing the asset or liability based on the best information available. The carrying amounts shown for the Company’s cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximate fair value due to the short-term maturity of those instruments. The valuation is based on settlements of similar financial instruments all of which are short-term in nature and are generally settled at or near cost. Investments held in Rabbi Trust A non-qualified deferred compensation plan is available to certain executives. Under this plan, participants may elect to defer up to 70 % of their compensation. The Company invests the deferrals in participant-selected diversified investments that are held in a Rabbi Trust and which are classified within Other assets on the Consolidated Balance Sheets. The fair value of the investments held in the Rabbi Trust is based on the quoted market prices of the underlying mutual fund investments. These investments are based on the participants’ selected investments, which represent the underlying liabilities to the participants in the non-qualified deferred compensation plan. Gains and losses on these investments are included in Other (income) on the Consolidated Statements of Operations. Derivatives The Company’s objective in entering into derivative transactions is to manage its exposure to interest rate movements associated with its variable rate debt and changes in fuel prices. The Company recognizes derivatives as either assets or liabilities on the balance sheet and measures those instruments at fair value. The fair values of the derivative financial instruments are determined using widely accepted valuation techniques including discounted cash flow analysis based on the expected cash flows of each derivative. Although the Company has determined that the significant inputs, such as interest yield curve and discount rate, used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with the Company’s counterparties and its own credit risk utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2024 and September 30, 2024, the Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and determined that the credit valuation adjustments were not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. The following tables summarize the financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2024 and September 30, 2024: December 31, 2024 Carrying Value Level 1 Level 2 Level 3 Other assets: Investments held by Rabbi Trust $ 8.9 $ 8.9 $ — $ — Interest rate derivative contracts 8.7 — 8.7 — Total assets $ 17.6 $ 8.9 $ 8.7 $ — Accrued expenses and other current liabilities: Fuel derivative contracts $ ( 0.2 ) $ — $ ( 0.2 ) $ — Other liabilities: Obligation to Rabbi Trust ( 8.9 ) ( 8.9 ) — — Total liabilities $ ( 9.1 ) $ ( 8.9 ) $ ( 0.2 ) $ — September 30, 2024 Carrying Value Level 1 Level 2 Level 3 Other assets: Investments held by Rabbi Trust $ 9.7 $ 9.7 $ — $ — Total assets $ 9.7 $ 9.7 $ — $ — Accrued expenses and other current liabilities: Fuel derivative contracts $ ( 0.5 ) $ — $ ( 0.5 ) $ — Other liabilities: Interest rate derivative contracts ( 2.5 ) — ( 2.5 ) — Obligation to Rabbi Trust ( 9.7 ) ( 9.7 ) — — Total liabilities $ ( 12.7 ) $ ( 9.7 ) $ ( 3.0 ) $ — Hedging Activities As of December 31, 2024 and September 30, 2024, the Company’s outstanding derivatives qualified as cash flow hedges. The Company assesses whether derivatives used in hedging transactions are “highly effective” in offsetting changes in the cash flow of the hedged forecasted transactions. Regression analysis is used for the hedge relationships and high effectiveness is achieved when a statistically valid relationship reflects a high degree of offset and correlation between the fair values of the derivative and the hedged forecasted transaction. The entire change in the fair value for highly effective derivatives is reported in Other comprehensive income (loss) and subsequently reclassified into Interest expense, net (in the case of interest rate contracts) and Cost of services provided (in the case of fuel hedge contracts) in the Consolidated Statements of Operations when the hedged item affects earnings. If the hedged forecasted transaction is no longer probable of occurring, then the amount recognized in Accumulated other comprehensive income (loss) is released to earnings. Cash flows from the derivatives are classified in the same category as the cash flows from the underlying hedged transaction. Interest Rate Contracts The Company has exposures to variability in interest rates associated with its variable interest rate debt, which includes the Series B Term Loan. As such, the Company has entered into interest rate contracts to help manage interest rate exposure by economically converting a portion of its variable-rate debt to fixed-rate debt. Effective for the periods March 18, 2016 through December 31, 2022, the Company held interest rate swaps with a notional amount of $ 500.0 . In January 2023, the Company entered into an interest rate swap agreement with a notional amount of $ 500.0 and an interest rate collar agreement with a notional amount of $ 500.0 , each effective for the period January 31, 2023 through January 31, 2028. On August 28, 2023, the Company terminated $ 400.0 of the notional amount of its outstanding interest rate collar agreement. The notional amount of interest rate contracts was $ 600.0 at December 31, 2024 and September 30, 2024. As of December 31, 2024, net deferred gain on the interest rate contracts of $ 2.9 , net of taxes, is expected to be recognized in Interest expense over the next 12 months. The effects on the consolidated financial statements of the interest rate contracts which were designated as cash flow hedges were as follows: Three Months Ended 2024 2023 Income (Loss) recognized in Other comprehensive income (loss) $ 13.1 $ ( 14.5 ) Net income reclassified from Accumulated other comprehensive income (loss) into Interest expense 2.0 2.9 Fuel Contracts The Company has exposures to variability in fuel pricing associated with its purchase and usage of fuel during the ordinary course of business operating a large fleet of vehicles and equipment. As such, the Company has entered into gasoline hedge contracts to help reduce its exposure to volatility in the fuel markets. In March 2024, the Company entered into a fuel swap agreement with a notional volume of 4.0 million gallons covering the period March 4, 2024 through February 24, 2025. The net deferred loss on the fuel swap as of December 31, 2024 was immaterial and is expected to be recognized in Cost of services provided over the next 3 months. The effects on the consolidated financial statements of the fuel swap contracts which were designated as cash flow hedges were as follows: Three Months Ended 2024 2023 (Loss) recognized in Other comprehensive income (loss) $ — $ — Net loss reclassified from Accumulated other comprehensive income (loss) into Cost of services provided ( 0.4 ) —

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	11. Commitments and Contingencies Risk Management The Company carries general liability, auto liability, workers’ compensation, and employee health care insurance policies. In addition, the Company carries other reasonable and customary insurance policies for a Company of our size and scope, as well as umbrella liability insurance policies to cover claims over the liability limits contained in the primary policies. The Company’s insurance programs, for workers’ compensation, general liability, auto liability and employee health care for certain employees contain self-insured retention amounts, deductibles and other coverage limits (“self-insured liability”). Claims that are not self-insured as well as claims in excess of the self-insured liability amounts are insured. The Company uses estimates in the determination of the required reserves. These estimates are based upon calculations performed by third-party actuaries, as well as examination of historical trends and industry claims experience. The Company’s reserve for unpaid and incurred but not reported claims under these programs at December 31, 2024 was $ 172.5 , of which $ 51.9 was classified in current liabilities and $ 120.6 was classified in non-current liabilities in the accompanying unaudited Consolidated Balance Sheet. The Company’s reserve for unpaid and incurred but not reported claims under these programs at September 30, 2024 was $ 165.6 , of which $ 52.8 was classified in current liabilities and $ 112.8 was classified in non-current liabilities in the accompanying Consolidated Balance Sheet. While the ultimate amount of these claims is dependent on future developments, in management’s opinion, recorded reserves are adequate to cover these claims. The Company’s reserve for unpaid and incurred but not reported claims at December 31, 2024 includes $ 18.2 related to claims recoverable from third-party insurance carriers. Corresponding assets of $ 5.1 and $ 13.1 are recorded at December 31, 2024, as Other current assets and Other assets, respectively. The Company’s reserve for unpaid and incurred but not reported claims at September 30, 2024 includes $ 13.4 related to claims recoverable from third-party insurance carriers. Corresponding assets of $ 4.0 and $ 9.4 were recorded at September 30, 2024, as Other current assets and Other assets, respectively. Litigation Contingency From time to time, the Company is subject to legal proceedings and claims in the ordinary course of its business, principally claims made alleging injuries (including vehicle and general liability matters as well as workers’ compensation and property casualty claims). Such claims, even if lacking merit, can result in expenditures of significant financial and managerial resources. In the ordinary course of its business, the Company is also subject to investigations or claims involving current and/or former employees and disputes involving commercial and regulatory matters. Regulatory matters include, among other things, audits and reviews of local and federal tax compliance, safety and employment practices, and environmental matters. Although the process of resolving regulatory matters and claims through litigation and other means is inherently uncertain, the Company is not aware of any such matter, legal proceeding or claim that it believes will have, individually or in the aggregate, a material effect on the Company, its financial condition, and results of operations or cash flows. For all legal matters, an estimated liability is established in accordance with the loss contingencies accounting guidance. This estimated liability is included in Accrued expenses and other current liabilities in the accompanying Consolidated Balance Sheets.

Segment Reporting [Abstract]
Segments	12 . Segments The operations of the Company are conducted through two operating segments: Maintenance Services and Development Services, which are also its reportable segments. Maintenance Services primarily consists of recurring landscape maintenance services and snow removal services as well as supplemental landscape enhancement services. Development Services primarily consists of landscape architecture and development services for new construction and large scale redesign projects. The operating segments identified above are determined based on the services provided, and they reflect the manner in which operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”) to allocate resources and assess performance. The CODM is the Company’s Chief Executive Officer. The CODM evaluates the performance of the Company’s operating segments based upon Net Service Revenues, Adjusted EBITDA and Capital Expenditures. Management uses Adjusted EBITDA to evaluate performance and profitability of each operating segment. The accounting policies of the segments are the same as those described in Note 2 “Summary of Significant Accounting Policies” in the notes to our consolidated financial statements in the Annual Report on Form 10-K for the fiscal year ended September 30, 2024 . As previously disclosed, effective October 1, 2024, certain expenses previously classified as "Corporate", including corporate executive compensation, finance, legal and information technology and other corporate costs, are allocated to the two reportable segments on a pro rata basis, based on segment revenue. Prior period segment results have been recast to be consistent with the current presentation. There were no changes to the Company's consolidated financial statements. Eliminations represent eliminations of intersegment revenues. The Company does not currently provide asset information by segment, as this information is not used by management when allocating resources or evaluating performance. The following is a summary of certain financial data for each of the segments: Three Months Ended 2024 2023 Maintenance Services $ 409.3 $ 442.3 Development Services 191.8 185.4 Eliminations ( 1.9 ) ( 1.0 ) Net Service Revenues $ 599.2 $ 626.7 Maintenance Services $ 41.7 $ 8.6 Development Services 17.0 1.5 Capital Expenditures $ 58.7 $ 10.1 Maintenance Services $ 34.6 $ 31.4 Development Services 17.5 15.3 Segment Adjusted EBITDA (1) $ 52.1 $ 46.7 (1) Presented below is a reconciliation of (Loss) before income taxes to Segment Adjusted EBITDA: Three Months Ended 2024 2023 Segment Adjusted EBITDA $ 52.1 $ 46.7 Interest expense, net 14.2 17.1 Depreciation expense 30.4 25.6 Amortization expense 8.1 10.1 Business transformation and integration costs (a) 9.2 10.7 Equity-based compensation (b) 4.8 5.3 (Loss) before income taxes $ ( 14.6 ) $ ( 22.1 ) (a) Business transformation and integration costs consist of severance and related costs, information technology, infrastructure, transformation, and other costs. These costs represent expenses related to distinct initiatives, typically significant enterprise-wide changes, including actions taken as part of the Company's One BrightView initiative. Such expenses are excluded from Segment Adjusted EBITDA disclosed above since such expenses vary in amount based on occurrence as well as factors specific to each of the activities, are outside of the normal operations of the business, and create a lack of comparability between periods.

Earnings Per Share [Abstract]
(Loss) Per Share of Common Stock	14 . (Loss) Per Share of Common Stock The Company calculates basic and diluted (loss) earnings per common share using the two-class method. The two-class method is an allocation formula that determines net (loss) income per common share for each share of common stock and Series A Convertible Preferred Stock, a participating security, according to dividends declared and participation rights in undistributed earnings. Under this method, all earnings (distributed and undistributed) are allocated to common shares and Series A Convertible Preferred Stock based on their respective rights to receive dividends. The holders of the Series A Convertible Preferred Stock do not participate in losses. The holders of Series A Convertible Preferred Stock participate in cash dividends that the Company pays on its common stock in an as-converted basis. Diluted net (loss) income per common share is computed based on the weighted average number of shares of common stock outstanding during each period, plus potential common shares considered outstanding during the period, as long as the inclusion of such awards is not antidilutive. Potential common shares consist of unvested and unexercised stock compensation awards and the Series A Convertible Preferred Stock, using the more dilutive of either the two-class method or if-converted stock method. Set forth below is a reconciliation of the numerator and denominator for basic and diluted (loss) earnings per share calculation for the periods indicated: Three Months Ended 2024 2023 Basic (Loss) per common share Numerator: Net (loss) $ ( 10.4 ) $ ( 16.4 ) Less: dividends on Series A convertible preferred shares ( 9.0 ) ( 8.9 ) Less: Earnings allocated to Convertible Preferred Shares — — Net (loss) available to common shareholders $ ( 19.4 ) $ ( 25.3 ) Denominator: Weighted average number of common shares outstanding – basic 95,166,000 93,986,000 Basic (loss) per share $ ( 0.20 ) $ ( 0.27 ) Diluted (loss) per common share Numerator: Net (loss) available to common shareholders – diluted $ ( 19.4 ) $ ( 25.3 ) Denominator: Weighted average number of common shares outstanding – basic 95,166,000 93,986,000 Dilutive effect of: Stock compensation awards — — Series A convertible preferred stock — — Weighted average number of common shares outstanding – diluted 95,166,000 93,986,000 Diluted (loss) per share $ ( 0.20 ) $ ( 0.27 ) Other Information: Weighted average number of anti-dilutive Series A convertible preferred shares, options and restricted stock (a) 58,942,000 59,434,000 (a) Weighted average number of anti-dilutive options is based upon the average closing price of the Company’s common stock on the NYSE for the period.
