Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business, Basis of Presentation and Summary of Significant Accounting Policies	Business, Basis of Presentation and Summary of Significant Accounting Policies Business Founded in 1971, GMS Inc. (together with its consolidated subsidiaries, “we,” “our,” “us,” “GMS” or the “Company”), through its wholly owned operating subsidiaries, operates a network of more than 300 distribution centers with extensive product offerings of wallboard, ceilings, steel framing and complementary construction products. The Company also operates more than 100 tool sales, rental and service centers. Through these operations, the Company provides a comprehensive selection of building products and solutions for its residential and commercial contractor customer base across the United States and Canada. The Company’s operating model combines the benefits of a national platform and strategy with a local go-to-market focus, enabling the Company to generate significant economies of scale while maintaining high levels of customer service. Principles of Consolidation The consolidated financial statements present the results of operations, financial position, stockholders’ equity and cash flows of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The results of operations of businesses acquired are included from their respective dates of acquisition. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Foreign Currency Translation Assets and liabilities of the Company’s Canadian subsidiaries are translated at the exchange rate prevailing at the balance sheet date, while income and expenses are translated at average rates for the period. Translation gains and losses are reported as a separate component of stockholders’ equity and other comprehensive income. Gains and losses on foreign currency transactions are recognized in the Consolidated Statements of Operations and Comprehensive Income within other income, net. Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. The Company maintains cash at financial institutions in excess of federally insured limits. Though the Company has not experienced any losses on its cash and cash equivalents to date and does not anticipate incurring any losses, there is no assurance that the Company will not experience losses on its cash and cash equivalents. Trade Accounts Receivable The Company records accounts and notes receivable net of allowances, including an allowance for expected credit losses. The Company maintains an allowance for estimated losses due to the failure of customers to make required payments, as well as allowances for cash discounts. The Company’s estimate of the allowance for expected credit losses is based on an assessment of individual past due accounts, historical loss information, accounts receivable aging and current economic factors and the Company’s expectation of future economic conditions. Account balances are written off when the potential for recovery is considered remote. Other receivables primarily include vendor rebate receivables. Other allowances include reserves for cash discounts and reserves for service charges. The Company routinely assesses the financial strength of its customers and generally does not require collateral. Concentrations of credit risk with respect to trade accounts receivable are limited due to the large number of geographically diverse customers comprising the Company’s customer base. Inventories Inventories primarily consist of finished goods purchased for resale and include wallboard, ceilings, steel framing and complementary products. Included within complementary products are parts, merchandise and tools held for sale. Inventories are valued at the lower of cost or market (net realizable value). The cost of inventories is determined by the moving average cost method. The Company routinely evaluates inventory for excess or obsolescence and considers factors such as historical usage rates and demand. Property and Equipment Property and equipment are recorded at cost less accumulated depreciation. Property and equipment obtained through business combinations are stated at estimated fair value as of the acquisition date. Expenditures for improvements are capitalized, while the costs of maintenance and repairs are charged to operating expense as incurred. Gains and losses related to the sale of property and equipment are recorded in selling, general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income. Depreciation expense for property and equipment of U.S. subsidiaries is determined using the straight-line method over the estimated useful lives of the various asset classes. The estimated useful lives of property and equipment are as follows: Buildings 25 - 39 years Furniture, fixtures and automobiles 3 - 5 years Computer hardware and software 3 - 5 years Warehouse, delivery equipment and tools 3 - 10 years Leasehold improvements Shorter of estimated useful life or lease term Depreciation expense for property and equipment of Canadian subsidiaries is recognized over the estimated useful lives of the various asset classes as follows: Vehicles and trucks 30% - 40% declining balance Furniture and fixtures 8% - 20% declining balance Buildings 4% declining balance Machinery and equipment 30% declining balance Leasehold improvements Straight-line over shorter of estimated useful life or lease term Goodwill Goodwill is the excess of the consideration transferred over the fair value of identifiable net assets acquired in business combinations accounted for under the acquisition method of accounting. The Company does not amortize goodwill. The Company tests its goodwill annually during the fourth quarter of its fiscal year or when events and circumstances indicate goodwill might be impaired. Impairment testing of goodwill is required at the reporting unit level (operating segment or one level below operating segment). The Company may make a qualitative assessment of the likelihood of goodwill impairment to determine whether a detailed quantitative analysis is required. The quantitative impairment test involves comparing the estimated fair values of the Company’s reporting units with the reporting units’ carrying amounts, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, a goodwill impairment loss is measured as the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. Intangible Assets Intangible assets consist of customer relationships, trade names and other assets acquired in conjunction with the purchases of businesses or purchases of assets from other companies. The Company typically uses an income method to estimate the acquisition date fair value of intangible assets obtained through a business combination, which is based on forecasts of the expected future cash flows attributable to the respective assets. When management determines material intangible assets are acquired in conjunction with the purchase of a business, the Company determines the fair values of the identifiable intangible assets by considering management’s own analysis and an independent third-party valuation specialist’s appraisal. Intangible assets determined to have definite lives are amortized over their estimated useful lives. Intangible assets determined to have indefinite lives are tested for impairment annually during the fourth quarter of the Company's fiscal year or when events and circumstances indicate that it is more likely than not that the asset is impaired. Long-Lived Assets The Company evaluates the recoverability of long-lived assets, including property and equipment, operating lease right-of-use ("ROU") assets and definite-lived intangible assets, for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used or a significant adverse change that would indicate the carrying amount of an asset or group of assets is not recoverable. For long-lived assets to be held and used, the Company recognizes an impairment loss if the carrying amount is not recoverable through the undiscounted cash flows and measures an impairment loss, if any, based on the difference between the carrying amount and fair value. Long-lived assets held for sale are reported at the lower of cost or fair value less costs to sell and are recorded within prepaid expenses and other current assets in the Consolidated Balance Sheets. The Company classifies assets as held for sale if it commits to a plan to sell the asset within one year and actively markets the asset in its current condition for a price that is reasonable in comparison to its estimated fair value. Leases The Company leases certain facilities, distribution and warehouse equipment and fleet of vehicles. The Company’s leases have lease terms ranging from one one The Company determines if an arrangement is a lease at inception and evaluates whether the lease meets the classification criteria of a finance or operating lease. Operating leases are included in operating lease right-of-use assets, current portion of operating lease liabilities and long-term operating lease liabilities in the Consolidated Balance Sheets. Finance leases are included in property and equipment, current portion of long-term debt long-term debt Lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of the future lease payments over the lease term. If readily determinable, the rate implicit in the lease is used to discount lease payments to present value. For leases in which the implicit rate is not readily determinable, the Company uses its incremental borrowing rate in determining the present value of future payments. The Company determines its incremental borrowing rate based on the applicable lease terms and the current economic environment. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments. Lease ROU assets also include any lease payments made in advance and exclude lease incentives and initial direct costs incurred. Some of the Company’s lease agreements contain rent escalation clauses (including index-based escalations), rent holidays, capital improvements funding or other lease concessions. Lease expense is recognized on a straight-line basis based on the fixed component over the lease term. Reductions in ROU assets and changes in lease liabilities are presented on a net basis within other non-current assets and liabilities within the operating section of the Company's Consolidated Statement of Cash Flows. Variable lease costs consist primarily of taxes, insurance and common area or other maintenance costs for leased facilities and vehicles and equipment, which are expensed as incurred. The Company also made the accounting policy election to not separate lease components from non-lease components related to its fleet of vehicles. Insurance Liabilities The Company is self-insured for certain losses related to medical claims. The Company has stop-loss coverage to limit the exposure arising from medical claims. In addition, the Company has deductible-based insurance policies for certain losses related to general liability, automobile and workers’ compensation. The expected ultimate cost for claims incurred as of the balance sheet date is not discounted and is recognized as a liability if probable and estimable. Insurance losses for claims filed and claims incurred but not reported are accrued based upon estimates of the aggregate liability for uninsured claims using historical loss development factors and actuarial assumptions followed in the insurance industry. The following table presents the Company’s aggregate liabilities for medical self-insurance, general liability, automobile and workers’ compensation and the expected recoveries for medical self-insurance, general liability, automobile and workers’ compensation. Liabilities for medical self-insurance are included in other accrued expenses and current liabilities. Reserves for general liability, automobile and workers’ compensation are included in other accrued expenses and current liabilities and other liabilities in the Consolidated Balance Sheets. Expected recoveries for insurance liabilities are included in prepaid expenses and other current assets and other assets in the Consolidated Balance Sheets. April 30, 2024 2023 (in thousands) Medical self-insurance $ 6,067 $ 4,275 General liability, automobile and workers’ compensation 22,731 20,502 Expected recoveries for insurance liabilities (3,746) (3,531) Restructuring The Company recognizes a liability for costs associated with an exit or disposal activity when the liability is incurred. After the appropriate level of management approves the detailed restructuring plan and the criteria for recognition are met, the Company establishes accruals for employee termination and other costs, as applicable. Restructuring costs are classified within selling, general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income. Debt Issuance Costs The Company defers debt issuance costs and amortizes them over the term of the related debt. The Company uses the straight-line method to amortize debt issuance costs for its revolving credit facilities and uses the effective interest method to amortize debt issuance costs for its other debt facilities. Amortization of debt issuance costs is recorded in interest expense in the Consolidated Statements of Operations and Comprehensive Income. The Company classifies debt issuance costs for its revolving credit facilities as an asset in the Consolidated Balance Sheets and classifies debt issuance costs for its other debt facilities as a reduction of the related debt in the Consolidated Balance Sheets. Stock Appreciation Rights, Deferred Compensation and Liabilities to Noncontrolling Interest Holders Certain subsidiaries have equity-based compensation agreements with the subsidiary’s employees and minority stockholders. These agreements are stock appreciation rights, deferred compensation agreements and liabilities to noncontrolling interest holders. Since these agreements are typically settled in cash or notes, they are accounted for as liability awards and measured at fair value. See Note 13, “Stock Appreciation Rights, Deferred Compensation and Redeemable Noncontrolling Interests,” for additional information with respect to these agreements. Derivative Instruments The Company has entered into derivative instruments to manage its exposure to certain financial risks. The Company’s derivative financial instruments are recognized as either assets or liabilities in the Consolidated Balance Sheets and measured at fair value. Derivative instruments that do not qualify as a hedge or are not designated as a hedge are adjusted to estimated fair value in earnings. Derivative instruments that meet hedge criteria are designated as hedges. For derivative instruments designated as a cash flow hedge, the Company recognizes the change in fair value, net of taxes, to accumulated other comprehensive income (loss) in the Consolidated Balance Sheets, and an amount is reclassified out of accumulated other comprehensive income (loss) into earnings to offset the earnings impact that is attributable to the risk being hedged. See Note 14, “Fair Value Measurements,” for additional information with respect to the Company’s derivative instruments. Revenue Recognition General. Revenue is recognized upon transfer of control of promised goods to customers at an amount that reflects the consideration the Company expects to receive in exchange for those goods. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. The Company includes shipping and handling costs billed to customers in net sales. These costs are recognized as a component of selling, general and administrative expenses. See Note 16, “Segments,” for information regarding disaggregation of revenue, including revenue by product and by geographic area. Performance Obligations. The Company satisfies its performance obligations at a point in time, which is upon delivery of products. The Company’s payment terms vary by the type and location of its customers. The amount of time between point of sale and when payment is due is not significant and the Company has determined its contracts do not include a significant financing component. The Company’s contracts with customers involve performance obligations that are one year or less. Therefore, the Company applied the standard’s optional exemption that permits the omission of information about its unfulfilled performance obligations as of the balance sheet dates. Significant Judgments. The Company’s contracts may include terms that could cause variability in the transaction price, including customer rebates, returns and cash discounts for prompt payment. Variable consideration is estimated and included in the transaction price based on the expected value method. These estimates are based on historical experience, anticipated performance and other factors known at the time. The Company only includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Cost of Sales Cost of sales reflects the direct cost of goods purchased from third parties, rebates earned from vendors, adjustments for inventory reserves and the cost of inbound freight. Vendor Rebates Typical arrangements with vendors provide for the Company to receive a rebate of a specified amount after it achieves any of a number of measures generally related to the volume of the Company's purchases over a period of time. The Company records these rebates to effectively reduce its cost of sales in the period in which the Company sells the product. Throughout the year, the Company estimates the amount of rebates receivable for the periodic programs based upon the expected level of purchases. The Company accrues for the receipt of vendor rebates based on purchases and reduces inventory to reflect the deferral of cost of sales. Selling, General and Administrative Expenses Selling, general and administrative expenses include expenses related to the delivery and warehousing of the Company's products, as well as employee compensation and benefits expenses for employees in the Company's branches and yard support center, as well as other administrative expenses, such as legal, accounting and information technology costs. Selling, general and administrative expenses included delivery expenses of $352.5 million, $324.9 million and $275.0 million during the years ended April 30, 2024, 2023 and 2022, respectively. Advertising Expense The cost of advertising is expensed as incurred and included in selling, general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income. Advertising expenses were $7.4 million, $6.0 million and $4.2 million during the years ended April 30, 2024, 2023 and 2022, respectively. Equity-Based Compensation As of April 30, 2024, the Company had various stock-based compensation plans, which are more fully described in Note 12, “Equity-Based Compensation.” The Company measures compensation cost for all share-based awards at fair value on the grant date (or measurement date if different) and recognizes compensation expense, net of forfeitures, over the requisite service period for awards expected to vest. The Company estimates the fair value of stock options using the Black-Scholes valuation model and determines the fair value of restricted stock units based on the quoted price of GMS common stock on the date of grant. Income Taxes Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized based on the difference between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Inherent in the measurement of deferred balances are certain judgments and interpretations of existing tax law and published guidance as applicable to our operations. The Company evaluates its deferred tax assets to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, we consider both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The primary negative evidence considered includes the cumulative operating losses generated in prior periods. The primary positive evidence considered includes the reversal of deferred tax liabilities related to depreciation and amortization that would occur within the same jurisdiction and during the carry-forward period necessary to absorb the federal and state net operating losses and other deferred tax assets. The reversal of such liabilities supports the realizability of the federal and state net operating losses and other deferred tax assets. The Company records amounts for uncertain tax positions that management believes are supportable but are potentially subject to successful challenge by the applicable taxing authority. Consequently, changes in our assumptions and judgments could materially affect amounts recognized related to income tax uncertainties and may affect our results of operations or financial position. We believe our assumptions for estimates are reasonable, although actual results may have a positive or negative material impact on the balances of such tax positions. Historically, the variation of estimates to actual results is not significant and material variation is not expected in the future. Concentrations of Risk Credit Risk. Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents and trade accounts and notes receivable. The Company assesses the credit standing of counterparties as considered necessary. The Company routinely assesses the financial strength of its customers and generally does not require collateral. Concentrations of credit risk with respect to trade accounts receivable are limited due to the substantial number of geographically diverse customers comprising the Company’s customer base. Additionally, the Company maintains allowances for expected credit losses. The Company does not enter into financial instruments for trading or speculative purposes. As of April 30, 2024 and 2023, no customer accounted for more than 10% of gross accounts receivable. Supply Risk. The Company purchases most of its inventories from a select group of vendors. Without these vendors, the Company’s ability to acquire inventory would be significantly impaired. Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Authoritative guidance for fair value measurements establishes a three-level hierarchy that prioritizes the inputs to valuation models based upon the degree to which they are observable. The three levels of the fair value measurement hierarchy are as follows: Level 1 Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. Level 2 Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 Inputs are unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. The carrying values of the Company’s cash, cash equivalents, trade receivables and trade payables approximate their fair values because of their short-term nature. Based on borrowing rates available to the Company for loans with similar terms, the carrying values of the Company’s variable rate debt instruments approximate fair value. See Note 14, “Fair Value Measurements,” for additional information with respect to the Company’s fair value measurements. Earnings Per Share Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of outstanding shares of common stock for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock, including stock options and restricted stock units (collectively “Common Stock Equivalents”), were exercised or converted into common stock. The dilutive effect of outstanding stock options and restricted stock units is reflected in diluted earnings per share by application of the treasury stock method. In applying the treasury stock method for stock-based compensation arrangements, the assumed proceeds are computed as the sum of the amount the employee must pay upon exercise and the amount of compensation cost attributed to future services and not yet recognized. Diluted earnings per share is computed by increasing the weighted-average number of outstanding shares of common stock computed in basic earnings per share to include the dilutive effect of Common Stock Equivalents for the period. In periods of net loss, the number of shares used to calculate diluted loss per share is the same as basic net loss per share. Recently Issued Accounting Pronouncements Segment Reporting . In November 2023, the Financial Accounting Standards Board ("FASB") issued new guidance to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses regularly provided to the chief operating decision maker ("CODM"). The new guidance is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. The new guidance will apply retrospectively to all periods presented. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements. Income Taxes. In December 2023, the FASB issued new guidance t o enhance income tax disclosures, primarily through changes in the rate reconciliation and income taxes paid disclosures . The new guidance is effective for fiscal years beginning after December 15, 2024. The new guidance will apply on a prospective basis to annual financial statements for periods beginning after the effective date. However, retrospective application in all prior periods presented is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

Business Combination and Asset Acquisition [Abstract]
Business Combinations	Business Combinations The Company accounts for business combinations by recognizing the assets acquired and liabilities assumed at the acquisition date fair value. In valuing certain acquired assets and liabilities, fair value estimates use Level 3 inputs, including future expected cash flows and discount rates. Goodwill is measured as the excess of consideration transferred over the fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to value assets acquired and liabilities assumed at the acquisition date, the Company’s estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments arising from new facts and circumstances are recorded to the Consolidated Statements of Operations and Comprehensive Income. The results of operations of acquisitions are reflected in the Company’s Consolidated Financial Statements from the date of acquisition. The Company's Consolidated Statement of Operations and Comprehensive Income for the year ended April 30, 2024 included $71.5 million of net sales and $5.4 million of net loss from acquisitions made in fiscal 2024. The Company recorded transaction costs of $4.9 million, $2.0 million and $3.5 million during the years ended April 30, 2024, 2023 and 2022, respectively. Fiscal 2024 Acquisitions In fiscal 2024, the Company completed the following acquisitions, with an aggregate preliminary purchase price of $380.0 million of cash consideration.

Home Lumber is a leading supplier of lumber, engineered wood, doors, framing packages and siding as well as other key complementary building materials in the Vancouver Island market. Home Lumber operates from a single location in Victoria, Canada. The primary purpose of the transaction was to expand the geographical coverage of the Company and grow the business. On October 1, 2023, the Company acquired AMW Construction Supply, LLC ("AMW"), a tools and fasteners and other complementary products distributor servicing the Phoenix, Arizona metro area. AMW operates from a single location in Phoenix, Arizona. The primary purpose of the transaction was to expand the Company's complementary product offerings and grow the business. On March 1, 2024, the Company acquired Kamco Supply Corporation and affiliates ("Kamco"), a leading regional supplier of ceilings, wallboard, steel, lumber, and other related construction products. Kamco operates five distribution facilities in the greater New York City area and services the New York metro and tri-state area. The transaction was funded with cash on hand and borrowings under the Company’s revolving credit facility. The primary purpose of the transaction was to expand the geographical coverage of the Company and grow the business. The assets acquired and liabilities assumed were recognized at their acquisition date fair values. The acquisition accounting is subject to change as the Company obtains additional information during the measurement period about the facts and circumstances that existed as of the acquisition dates. The primary areas of the preliminary acquisition accounting that are not yet finalized relate to preliminary fair value estimates, working capital adjustments and residual goodwill. The following table summarizes the preliminary acquisition accounting for these acquisitions, and subsequent measurement period adjustments recorded, based on currently available information: Initial Adjustments Updated (in thousands) Cash $ 3,028 $ — $ 3,028 Trade accounts and notes receivable 37,355 154 37,509 Inventories 25,713 37 25,750 Prepaid and other current assets 411 (32) 379 Property and equipment 17,035 — 17,035 Operating lease right-of-use assets 61,703 — 61,703 Customer relationships 124,954 (4,353) 120,601 Trade names 44,064 (664) 43,400 Non-compete agreements 4,600 — 4,600 Goodwill 151,726 3,700 155,426 Accounts payable and accrued expenses (21,925) (208) (22,133) Operating lease liabilities (61,703) — (61,703) Deferred income taxes (6,586) 963 (5,623) Fair value of consideration transferred $ 380,375 $ (403) $ 379,972 Goodwill recognized is attributable to synergies achieved through the streamlining of operations combined with improved margins attainable through increased market presence and is attributable to the Company's geographic divisions reportable segment. Goodwill of $17.2 million is not expected to be deductible for U.S. federal income tax purposes, and goodwill of $138.2 million is expected to be deductible for U.S. federal income tax purposes. The estimated useful life for the customer relationships is 12.1 years, the estimated useful life for the trade names is 15 years and the estimated useful lives for the non-competition agreements is 5.0 years. Trade accounts and notes receivable had an estimated fair value of $37.5 million and a gross contractual value of $38.0 million. The difference represents the Company’s best estimate of the contractual cash flows that will not be collected. Pro Forma Financial Information The following table presents the unaudited pro forma consolidated net sales and net income for the Company for the periods indicated: Year Ended Year Ended April 30, 2024 April 30, 2023 (in thousands) Net sales $ 5,711,196 $ 5,622,824 Net income 263,482 332,831 The above pro forma results have been calculated by combining the historical results of the Company, Jawl, AMW and Kamco as if the acquisitions of Jawl, AMW and Kamco had occurred on May 1, 2022, the first day of the comparable prior reporting period.

During the year ended April 30, 2024, the Company recorded measurement period adjustments related to its Engler, Meier and Justus, Inc. and Blair Building Materials, Inc. acquisitions. The annual impairment test during the fourth quarter of fiscal 2024 indicated that the fair value of the Company’s reporting units exceeded their carrying values. The Com pany identified ten reporting units for evaluating goodwill for the fiscal 2024 annual impairment test, which were Central, Midwest, New York, Northeast, Southern, Southeast, Southwest, Western, Canada and Ames. Each of these reporting units constitutes a business for which discrete financial information is available and segment management regularly reviews the operating results. The Company evaluates its reporting units on an annual basis. The Company estimates the fair values of its reporting units based on weighting of the income and market approaches. These models use significant unobservable inputs, or Level 3 inputs, as defined by the fair value hierarchy. Under the income approach, the Company calculates the fair value of the reporting unit based on the present value of estimated cash flows using a discounted cash flow method. The significant assumptions used in the discounted cash flow method include internal forecasts and projections developed by management for planning purposes, available industry/market data, discount rates and the growth rate to calculate the terminal value. Under the market approach, the fair value is estimated using the guideline company method. The Company selects guideline companies in the industry in which each reporting unit operates. The Company primarily uses EBITDA multiples based on the multiples of the selected guideline companies. Intangible Assets The following tables present the components of the Company’s definite-lived intangible assets: Estimated Weighted April 30, 2024 Gross Accumulated Net (dollars in thousands) Customer relationships 5 - 15 12.8 $ 695,411 $ (395,117) $ 300,294 Definite-lived trade names 5 - 20 15.4 143,267 (32,613) 110,654 Vendor agreements 10 10.0 1,000 (675) 325 Developed technology 5 - 10 6.9 8,249 (5,843) 2,406 Other 3 - 5 4.8 5,142 (500) 4,642 Definite-lived intangible assets 13.1 $ 853,069 $ (434,748) $ 418,321 Indefinite-lived intangible assets 84,367 Total intangible assets, net $ 502,688 Estimated Weighted April 30, 2023 Gross Accumulated Net (dollars in thousands) Customer relationships 5 - 16 12.4 $ 669,142 $ (432,220) $ 236,922 Definite-lived trade names 5 - 20 15.6 100,326 (25,407) 74,919 Vendor agreements 8 - 10 10.0 1,000 (575) 425 Developed technology 5 - 10 6.9 8,261 (5,596) 2,665 Other 3 - 5 3.2 1,551 (1,189) 362 Definite-lived intangible assets 12.8 $ 780,280 $ (464,987) $ 315,293 Indefinite-lived intangible assets 84,367 Total intangible assets, net $ 399,660 The Company’s indefinite-lived intangible assets, other than goodwill, consist of trade names that had a carrying amount of $84.4 million as of April 30, 2024 and 2023. In connection with the Company's annual impairment test during the fourth quarter of fiscal 2024, the Company performed a quantitative assessment of the carrying value of its indefinite-lived intangible assets. Based on the Company's assessment, the Company concluded there was no impairment of its indefinite-lived intangible assets. Definite-lived intangible assets are amortized over their estimated useful lives. The Company amortizes its customer relationships using an accelerated method to match the estimated cash flow generated by such assets and amortizes its other definite-lived intangibles using the straight-line method because a pattern to which the expected benefits will be consumed or otherwise used up could not be reliably determined. Amortization expense related to definite-lived intangible assets was $64.2 million, $65.7 million and $63.8 million during the years ended April 30, 2024, 2023 and 2022, respectively, and is recorded in depreciation and amortization expense in the Consolidated Statements of Operations and Comprehensive Income.

The indebtedness and obligations under the Term Loan Facility are secured by a first-priority security interest in substantially all of the fixed assets of the Company and its subsidiaries (including the Company’s indirect Canadian subsidiaries) and a second-priority security interest in substantially all of the current assets of the Company and its subsidiaries (including the Canadian Subsidiaries), subject to exclusions as set forth in the Term Loan Facility and related loan documents. As of April 30, 2024, the applicable rate of interest was 7.57%. On May 12, 2023, the Company amended the Term Loan Facility to provide refinancing term loans in the aggregate principal amount of $500.0 million, the net proceeds of which were used, together with cash on hand, to refinance the then outstanding borrowings under the Term Loan Facility in the principal amount of $499.5 million and pay related fees. The amendment also amended the Term Loan Facility to, among other things, (i) replace Credit Suisse with JPMorgan as the administrative agent and collateral agent, (ii) extend the maturity date by seven years from the date of the amendment to May 12, 2030 and (iii) modify certain thresholds, baskets and amounts referenced therein. The amended Term Loan Facility bears interest at a floating rate per annum of SOFR plus 3.00%. The Company recorded a write-off of debt discount and deferred financing fees of $1.4 million, which is included in write-off of debt discount and deferred financing fees in the Consolidated Statement of Operations and Comprehensive Income for the year ended April 30, 2024. The amended Term Loan Facility permits the Borrower to add one or more incremental term loans up to (1) a fixed amount equal to the greater of (x) $500.0 million and (y) 100% of consolidated EBITDA for the most recently ended four fiscal quarter period plus (2) additional amounts subject to a secured first lien leverage ratio test not to exceed 3.50:1.00. The Company is required to make scheduled quarterly payments of $1.3 million, or 0.25% of the aggregate principal amount of the Term Loan Facility, with the balance due May 12, 2030. Provided that the individual affected lenders agree accordingly, the maturities of the Term Loan Facility may, upon the Borrower’s request and without the consent of any other lender, be extended. GYP Holdings II Corp., the sole entity between Borrower and the financial reporting entity, is a holding company with no other operations, assets, liabilities or cash flows other than through its ownership of the Borrower and its operating subsidiaries. On February 2, 2024, the Company amended its Term Loan Facility to reduce the interest rate applicable to the outstanding borrowings under the Term Loan Facility. The applicable rate for term Secured Overnight Financing Rate ("SOFR") loans under the Term Loan Facility was reduced from a floating rate per annum of Term SOFR (as defined in the Term Loan Facility) plus 3.00% to a floating rate per annum of Term SOFR plus 2.25%, and the applicable rate for base rate loans under the Term Loan Facility was reduced from a floating rate per annum of the Base Rate (as defined in the Term Loan Facility) plus 2.00% to a floating rate per annum of the Base Rate plus 1.25%. The other material terms of the Term Loan Facility remain unchanged. The Company recorded a write-off of debt discount and deferred financing fees of $0.7 million, which is included in write-off of debt discount and deferred financing fees in the Consolidated Statement of Operations and Comprehensive Income for the year ended April 30, 2024. Asset Based Lending Facility The Company has an asset based lending facility ("ABL Facility") that provides for aggregate revolving commitments of $950.0 million. GYP Holdings III Corp. is the lead borrower (in such capacity, the “Lead Borrower”). Extensions of credit under the ABL Facility are limited by a borrowing base calculated periodically based on specified percentages of the value of eligible inventory and accounts receivable, subject to certain reserves and other adjustments. At the Company’s option, the interest rates applicable to the loans under the ABL Facility are based on SOFR or base rate plus, in each case, an applicable margin. The margins applicable for each elected interest rate are subject to a pricing grid, as defined in the ABL Facility agreement, based on average daily availability for the most recent fiscal quarter. The ABL Facility also contains an unused commitment fee. As of April 30, 2024, the weighted average interest rate on borrowings was 6.68%. On May 23, 2024, we amended our ABL Facility to replace the Canadian Dollar Offered Rate (CDOR) as the benchmark rate for borrowings under the Canadian revolving credit subfacility with the Canadian Overnight Repo Rate Average (CORRA). As of April 30, 2024, the Company had available borrowing capacity of $655.9 million under the ABL Facility. The ABL Facility matures on December 22, 2027. The ABL Facility contains a cross-default provision with the Term Loan Facility. Terms of the ABL Facility and Term Loan Facilities Collateral The ABL Facility is collateralized by (a) first priority perfected liens on the following assets of the Loan Parties (including the Canadian Subsidiaries): (i) accounts receivable; (ii) inventory; (iii) deposit accounts; (iv) cash and cash equivalents; (v) tax refunds and tax payments; (vi) chattel paper; and (vii) documents, instruments, general intangibles, securities accounts, books and records, proceeds and supporting obligations related to each of the foregoing, subject to certain exceptions (collectively, “ABL Priority Collateral”); and (b) second priority perfected liens on the remaining assets of the Loan Parties not constituting ABL Priority Collateral, subject to customary exceptions (collectively, “Term Priority Collateral”) and excluding real property. The Term Loan Facility is collateralized by (a) first priority liens on the Term Priority Collateral (including certain material real property) and (b) second priority liens on the ABL Priority Collateral, subject to customary exceptions. Prepayments The Term Loan Facility may be prepaid at any time. Under certain circumstances and subject to certain exceptions, the Term Loan Facility will be subject to mandatory prepayments in an amount equal to: • 100% of the net proceeds of certain asset sales and issuances or incurrences of nonpermitted indebtedness; and • 50% of annual excess cash flow for any fiscal year, such percentage to decrease to 25% or 0% depending on the attainment of certain total leverage ratio targets. As of April 30, 2024, there was no prepayment required related to excess cash flow. The ABL Facility may be prepaid at the Company’s option at any time without premium or penalty and will be subject to mandatory prepayment if the outstanding ABL Facility exceeds the lesser of (i) the borrowing base and (ii) the aggregate amount of commitments. Mandatory prepayments do not result in a permanent reduction of the lenders’ commitments under the ABL Facility. Guarantees Holdings guarantees the payment obligations under the ABL Facility and the Term Loan Facility. Certain of Holdings’ subsidiaries (i) guarantee the payment obligations under the Term Loan Facility (in such capacity, the “Subsidiary Guarantors”) and (ii) are co-borrowers under the ABL Facility. Covenants The ABL Facility and Term Loan Facility contain a number of covenants that limit the Company’s ability and the ability of the Company’s restricted subsidiaries, as described in the respective credit agreement, to incur more indebtedness; pay dividends, redeem or repurchase stock or make other distributions; make investments; create restrictions on the ability of our restricted subsidiaries to pay dividends to us or make other intercompany transfers; create liens securing indebtedness; transfer or sell assets; merge or consolidate; enter into certain transactions with our affiliates; and prepay or amend the terms of certain indebtedness. The Company was in compliance with all covenants under the ABL Facility and Term Loan Facility as of April 30, 2024. Events of Default The ABL Facility and Term Loan Facility also provide for customary events of default, including non-payment of principal, interest or fees, violation of covenants, material inaccuracy of representations or warranties, specified cross-default to other material indebtedness, certain bankruptcy events, certain ERISA events, material invalidity of guarantees or security interest, material judgments and changes of control. Senior Notes The Company has $350.0 million of senior notes ("Senior Notes") outstanding. The Senior Notes bear interest at 4.625% per annum and mature on May 1, 2029. Interest is payable semi-annually in arrears on May 1 and November 1. The Senior Notes are general senior unsecured obligations, rank equally in right of payment with all existing and future senior indebtedness of the Company, including the Term Loan Facility and ABL Facility, and are senior in right of payment to any existing and future subordinated indebtedness of the Company. The Senior Notes and the related guarantees are effectively subordinated to all existing and future secured indebtedness of the Company and the Company’s subsidiaries guaranteeing the notes, including indebtedness under the Term Loan Facility and the ABL Facility, to the extent of the value of the assets securing such indebtedness. The Senior Notes and the related guarantees are structurally subordinated to all of the existing and future indebtedness and other liabilities of the Company’s subsidiaries that do not guarantee the Senior Notes. The Company may redeem some or all the Senior Notes at any time on or after May 1, 2024, at the redemption prices set forth in the indenture, plus accrued and unpaid interest up to, but not including, the redemption date. If the Company sells certain assets or consummates certain change in control transactions, the Company will be required to make an offer to repurchase the Senior Notes. The indenture contains certain covenants that, among other things, limit the Company’s ability and the ability of its restricted subsidiaries to incur additional indebtedness, make certain dividends, repurchase Company stock or make other distributions, make certain investments, create liens, transfer or sell assets, merge or consolidate, and enter into transactions with the Company’s affiliates. Such covenants are subject to important exceptions and qualifications set forth in the indenture. The indenture also contains certain customary events of default, including failure to make payments in respect of the principal amount of the Senior Notes, failure to make payments of interest on the Senior Notes when due and payable, failure to comply with certain covenants and agreements and certain events of bankruptcy or insolvency. Installment Notes The Company’s installment notes include notes for subsidiary stock repurchases from stockholders, notes for the payout of stock appreciation rights and a note to the seller of an acquired company. See Note 13, “Stock Appreciation Rights, Deferred Compensation and Redeemable Noncontrolling Interests.” Debt Maturities As of April 30, 2024, the maturities of existing long-term debt and finance leases were as follows: Term Loan Facility ABL Facility Senior Notes Finance Leases Installment Notes Total Year Ending April 30, (in thousands) 2025 $ 4,988 $ — $ — $ 44,287 $ 1,574 $ 50,849 2026 4,988 — — 39,260 714 44,962 2027 4,988 — — 33,971 694 39,653 2028 4,988 270,000 — 27,408 620 303,016 2029 4,988 — — 16,578 568 22,134 Thereafter 472,563 — 350,000 7,234 — 829,797 $ 497,503 $ 270,000 $ 350,000 $ 168,738 $ 4,170 $ 1,290,411

The Company is subject to current tax on global intangible low-taxed income (“GILTI”) earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740 No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred. The Company has elected to recognize the tax on GILTI as a period expense in the period the tax is incurred. As of April 30, 2024, the Company’s assertion has not changed from the year ended April 30, 2023 that it does not intend to permanently reinvest its accumulated earnings in its non-U.S. subsidiaries and will continue to periodically distribute the earnings on an as needed basis. The Company does not anticipate significant tax consequences from any future distributions. NOLs . During recent tax years, the Company generated certain state net operating loss carry-forwards which are available for use against taxable income in each respective state. The Company had gross state net operating losses available for carry-forward of $37.4 million and $26.5 million as of April 30, 2024 and 2023, respectively, which expire beginning in 2029. Valuation allowance. Deferred tax assets and liabilities are computed by applying the federal and state income tax rates in effect to the gross amounts of temporary differences and other tax attributes, such as net operating loss carry-forwards. As of each reporting date, the Company considers new evidence, both positive and negative, that could affect the future realization of deferred tax assets. Valuation allowances are established if management believes that it is more likely than not the related tax benefits will not be realized. The valuation allowance as of April 30, 2024 and 2023 primarily relates to a portion of the outside basis difference that was created as a result of the impairment of goodwill recognized during the year ended April 30, 2020 and state tax attribute carryforwards. The net operating loss carryforwards expire beginning 2029. Uncertain tax positions. The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. The Company’s policy for recording penalties and interest associated with uncertain tax positions is to record such items as a component of selling, general and administrative expenses. The Company had no reserve for uncertain tax positions as of April 30, 2024 and 2023. As of April 30, 2024, the tax years ended April 30, 2021 through 2023 remain subject to examination by the U.S. Internal Revenue Service. As of April 30, 2024, the tax years ended April 30, 2021 and 2023 remain subject to examination by the Barbados Revenue Authority and the tax years ended April 30, 2021 through 2023 remain subject to examination by the Canada Revenue Agency.

Stockholders' Equity	Stockholders’ Equity Share Repurchase Program On October 18, 2023, the Company's Board of Directors approved an expanded share repurchase program under which the Company is authorized to repurchase up to $250.0 million of its outstanding common stock. This expanded program replaced the Company’s previous share repurchase authorization of $200.0 million. The Company may conduct repurchases under the share repurchase program through open market transactions, under trading plans in accordance with SEC Rule 10b5-1 and/or in privately negotiated transactions, in each case in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended. The timing and amount of any purchases of the Company's common stock are subject to a variety of factors, including, but not limited to, the Company’s liquidity, credit availability, general business and market conditions, debt covenants and the availability of alternative investment opportunities. The share repurchase program does not obligate the Company to acquire any amount of common stock, and it may be suspended or terminated at any time at the Company’s discretion. As of April 30, 2024, the Company had $200.5 million of remaining repurchase authorization under its stock repurchase program. Beginning January 1, 2023, share repurchases in excess of issuances are subject to a 1% excise tax. The Company includes the applicable excise tax as part of the cost basis of the shares acquired and records the taxes as a corresponding liability in accrued expenses and other liabilities in the Consolidated Balance Sheet. Shares repurchased pursuant to the Company’s share repurchase program are retired.

Equity-Based Compensation	12 Months Ended

Share-Based Payment Arrangement [Abstract]
Equity-Based Compensation	Equity-Based Compensation General The Company has granted options and restricted stock units to employees and non-employee directors to purchase the Company’s common stock under various stock incentive plans. The plans are administered by a committee of the Board of Directors, which determines the terms of the awards granted. The committee may grant various forms of equity-based incentive compensation, including stock options, stock appreciation rights, restricted stock, restricted stock units and performance awards, among others. Stock options are granted with an exercise price equal to the closing market value of GMS common stock on the date of grant, have a term of ten years, and vest over terms of three one Share-based compensation expense related to stock options and restricted stock units was $14.4 million, $12.2 million and $10.4 million during the years ended April 30, 2024, 2023 and 2022, respectively, and is included in selling, general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income. Stock Option Awards The following table presents stock option activity as of and for the year ended April 30, 2024: Number of Weighted Weighted Aggregate (shares and dollars in thousands) Outstanding as of April 30, 2023 1,106 $ 32.60 6.5 $ 28,155 Options granted 151 74.75 Options exercised (276) 22.97 Options forfeited (13) 42.73 Outstanding as of April 30, 2024 968 $ 41.79 6.7 $ 49,086 Exercisable as of April 30, 2024 633 $ 30.91 5.7 $ 38,995 Vested and expected to vest as of April 30, 2024 967 $ 41.79 6.7 $ 49,079 The aggregate intrinsic value represents the excess of the Company’s closing stock price on the last trading day of the period over the weighted average exercise price multiplied by the number of options outstanding, exercisable or expected to vest. Options expected to vest are unvested shares net of expected forfeitures. The total intrinsic value of options exercised during the years ended April 30, 2024, 2023 and 2022 was $15.7 million, $11.5 million and $7.5 million, respectively. As of April 30, 2024, there was $5.6 million of total unrecognized compensation cost related to stock options. That cost is expected to be recognized over a weighted-average period of 1.5 years. The fair value of stock options granted during the years ended April 30, 2024, 2023 and 2022 was estimated using the Black-Scholes option-pricing model with the following assumptions and resulting weighted average grant date fair value: Year Ended April 30, 2024 2023 2022 Volatility 38.70 % 45.80 % 43.13 % Expected life (years) 6.0 6.0 6.0 Risk-free interest rate 4.30 % 2.67 % 0.89 % Dividend yield — % — % — % Grant date fair value $ 33.33 $ 25.26 $ 20.86 The expected volatility was based on historical and implied volatility. The expected life of stock options was based on a simplified method using the midpoint between the vesting date and the end of the contractual term because the Company’s own historical share option exercise experience does not provide a reasonable basis for estimating expected term. The risk-free rate was based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the stock option. The expected dividend yield was 0%, as the Company has not declared any common stock dividends to date and does not expect to declare common stock dividends in the near future. The fair value of the underlying common stock at the date of grant was determined based on the value of the Company’s closing stock price on the date of the grant. Restricted Stock Units The following table presents restricted stock unit activity for the year ended April 30, 2024: Number of Weighted (shares in thousands) Outstanding as of April 30, 2023 353 $ 46.97 Granted 141 74.80 Vested (175) 44.53 Forfeited (5) 52.84 Outstanding as of April 30, 2024 314 $ 60.74 The total fair value of awards vested during the years ended April 30, 2024, 2023 and 2022 was $13.0 million, $9.0 million and $8.9 million, respectively. As of April 30, 2024, there was $7.7 million of total unrecognized compensation cost related to nonvested restricted stock units. That cost is expected to be recognized over a weighted-average period of 1.3 years. Employee Stock Purchase Plan The Company has an employee stock purchase plan (“ESPP”) which allows for qualified employees (as defined therein) to participate in the purchase of shares of the Company’s common stock at a price equal to 90% of the lower of the closing price at the beginning or end of the last day of the purchase period, which is a six-month period ending on December 31 and June 30 of each year. The ESPP authorizes the issuance of a total of 2.0 million shares, of which 1.5 million shares were still available for issuance as of April 30, 2024. Share-based compensation expense related to the ESPP was $1.2 million, $1.0 million and $0.6 million during the years ended April 30, 2024, 2023 and 2022, respectively. The following table presents the number of shares of the Company’s common stock purchased under the ESPP and average price per share: Year Ended April 30, 2024 2023 2022 (shares in thousands) Number of shares purchased under the ESPP 89 79 70 Average purchase price $ 51.74 $ 40.47 $ 33.19

Current and long-term liabilities for stock appreciation rights, deferred compensation and redeemable noncontrolling interests are included in other accrued expenses and liabilities and other liabilities, respectively, in the Condensed Consolidated Balance Sheets. The Company uses a lognormal binomial method to determine the fair value of stock appreciation rights, deferred compensation and redeemable noncontrolling interests at redemption date. Significant inputs used in this method include volatility rates, a discount rate, the expected time to redemption of the liabilities, historical values of the book equity of certain subsidiaries and market information for comparable entities. The use of these inputs to derive the fair value of the liabilities at a point in time can result in volatility in the financial statements. Stock Appreciation Rights Certain subsidiaries have granted stock appreciation rights to certain employees under which payments are dependent on the appreciation in the book value per share, adjusted for certain provisions, of the applicable subsidiary. Settlements of the awards can be made in a combination of cash or installment notes, generally paid over five years, upon a triggering event. As of April 30, 2024, all stock appreciation rights were vested. Liabilities related to these agreements are classified as share-based liability awards and are measured at fair value. Deferred Compensation Subsidiaries’ stockholders have entered into other deferred compensation agreements that granted the stockholders a payment based on a percentage in excess of book value, adjusted for certain provisions, upon an occurrence as defined in the related agreements. These instruments are redeemed in cash or installment notes, generally paid in annual installments over the five years following termination of employment. Liabilities related to these agreements are classified as share-based liability awards and are measured at fair value. Redeemable Noncontrolling Interests Noncontrolling interests were issued to certain employees of certain of the Company’s subsidiaries. The noncontrolling interest awards are subject to mandatory redemption on termination of employment for any reason. These instruments are redeemed in cash or installment notes, generally paid in annual installments over the five years following termination of employment. Under the terms of the employee agreements, the redemption value is determined based on the book value of the subsidiary, as adjusted for certain items. Liabilities related to these agreements are classified as share-based liability awards and are measured at fair value. Upon the termination of employment or other triggering events including death or disability of the noncontrolling stockholders in the Company’s subsidiaries, we have to purchase, or redeem, the noncontrolling interests at either an agreed upon price or a formula value provided in the stockholder agreements. This formula value is typically based on the book value per share of the subsidiary’s equity, including certain adjustments.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents the estimated carrying amount and fair value of the Company’s liabilities measured at fair value on a recurring basis: April 30, 2024 2023 (in thousands) Interest rate swaps and collars (Level 2) $ 11,260 $ — In connection with the amendment to the Term Loan Facility in May 2023, the Company entered into (a) two-year interest rate swap agreements effective May 31, 2023 and expiring April 30, 2025 with notional amounts totaling $300.0 million to convert the variable interest rate on a portion of the term loans outstanding to a fixed 1-month SOFR interest rate of 3.899% and (b) forward interest rate collars effective April 30, 2025 and expiring April 30, 2029 with notional amounts totaling $300.0 million. The objective of such hedging instruments is to reduce the variability of interest payment cash flows associated with the variable interest rates under the Term Loan Facility and otherwise hedge exposure to future interest rate fluctuations. The Company believes there have been no material changes in the creditworthiness of the counterparties to these interest rate swaps and believes the risk of nonperformance by each party is minimal. The Company designated the interest rate swaps and collars as cash flow hedges. As of April 30, 2024, $3.7 million was classified in prepaid expenses and other current assets and $7.6 million was classified in other assets in the Condensed Consolidated Balance Sheet. The Company recognized gains, net of tax, of $2.9 million in earnings during the year ended April 30, 2024 related to its interest rate swaps and collars. The Company recognized losses, net of tax, of $1.8 million and $8.9 million in earnings related to prior interest rate swaps during the years ended April 30, 2023 and 2022, respectively. These gains and losses are included in interest expense in the Consolidated Statements of Operations and Comprehensive Income and within cash flows from operating activities in the Consolidated Statements of Cash Flows. See Note 11, " Stockholders' Equity," for a reconciliation of the beginning and ending derivative loss in accumulated other comprehensive income. The fair value of interest rate swaps was determined using Level 2 inputs. The Company obtained the Level 2 inputs from its counterparties. Substantially all of the inputs throughout the full term of the instruments were derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. The fair value of the Company’s interest rate swap was determined using widely accepted valuation techniques including a discounted cash flow analysis on the expected cash flows of the derivative. This analysis reflected the contractual terms of the derivatives, including the period to maturity, and used observable market-based inputs, including interest rate curves and implied volatilities. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Disclosures are required for certain assets and liabilities that are measured at fair value on a nonrecurring basis in periods after initial recognition. Such measurements of fair value relate primarily to assets and liabilities measured at fair value in connection with business combinations and asset impairments. For more information on business combinations, see Note 2, “Business Combinations.” There were no material long-lived asset impairments during the years ended April 30, 2024, 2023 or 2022. Fair Value of Debt The estimated fair value of the Company’s Senior Notes was determined based on Level 2 input using observable market prices in less active markets. The carrying amount of the Company’s Term Loan Facility and ABL Facility approximates its fair value as the interest rates are variable and reflective of market rates. The following table presents the carrying value and fair value of the Company’s Senior Notes: April 30, 2024 April 30, 2023 Carrying Amount Fair Value Carrying Amount Fair Value (in thousands) Senior Notes $ 350,000 $ 323,330 $ 350,000 $ 308,000

Segment Reporting [Abstract]
Segments	Segments General The Company defines operating segments as components of the organization for which discrete financial information is available and operating results are evaluated on a regular basis by the Chief Operating Decision Maker (“CODM”) to assess performance and allocate resources. The Company’s CODM is its Chief Executive Officer. The Company has ten operating segments based on the Company’s nine geograp hic divisions, which are Central, Midwest, New York, Northeast, Southern, Southeast, Southwest, Western and Canada, and Ames. The acquisition of Kamco resulted in a new operating segment, New York. The Company aggregates its nine geographic divisions operating segments into one reportable segment based on similarities between the operating segments’ economic characteristics , nature of products sold, production process, type of customer and methods of distribution. The accounting policies of the operating segments are the same as those described in the summary of significant policies. In addition to the Company’s reportable segment, the Company’s consolidated results include both corporate activities and certain other activities. Corporate includes the Company’s corporate office building and support services provided to its subsidiaries. Other includes Tool Source Warehouse, Inc., which functions primarily as an internal distributor of tools, and Ames. Segment Results The CODM assesses the Company’s performance based on the periodic review of net sales, Adjusted EBITDA and certain other measures for each of the operating segments. Adjusted EBITDA is not a recognized financial measure under GAAP. However, we believe it assists investors and analysts in comparing our operating performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. Management believes Adjusted EBITDA is helpful in highlighting trends in our operating results, while other measures can differ significantly depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which companies operate and capital investments. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations -- Non-GAAP Financial Measures” for a further discussion of this non-GAAP measure.

Business, Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Apr. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements present the results of operations, financial position, stockholders’ equity and cash flows of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The results of operations of businesses acquired are included from their respective dates of acquisition.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Foreign Currency Translation	Foreign Currency Translation Assets and liabilities of the Company’s Canadian subsidiaries are translated at the exchange rate prevailing at the balance sheet date, while income and expenses are translated at average rates for the period. Translation gains and losses are reported as a separate component of stockholders’ equity and other comprehensive income. Gains and losses on foreign currency transactions are recognized in the Consolidated Statements of Operations and Comprehensive Income within other income, net.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. The Company maintains cash at financial institutions in excess of federally insured limits. Though the Company has not experienced any losses on its cash and cash equivalents to date and does not anticipate incurring any losses, there is no assurance that the Company will not experience losses on its cash and cash equivalents.
Trade Accounts Receivable	Trade Accounts Receivable The Company records accounts and notes receivable net of allowances, including an allowance for expected credit losses. The Company maintains an allowance for estimated losses due to the failure of customers to make required payments, as well as allowances for cash discounts. The Company’s estimate of the allowance for expected credit losses is based on an assessment of individual past due accounts, historical loss information, accounts receivable aging and current economic factors and the Company’s expectation of future economic conditions. Account balances are written off when the potential for recovery is considered remote. Other receivables primarily include vendor rebate receivables. Other allowances include reserves for cash discounts and reserves for service charges. The Company routinely assesses the financial strength of its customers and generally does not require collateral. Concentrations of credit risk with respect to trade accounts receivable are limited due to the large number of geographically diverse customers comprising the Company’s customer base.
Inventories	Inventories Inventories primarily consist of finished goods purchased for resale and include wallboard, ceilings, steel framing and complementary products. Included within complementary products are parts, merchandise and tools held for sale. Inventories are valued at the lower of cost or market (net realizable value). The cost of inventories is determined by the moving average cost method. The Company routinely evaluates inventory for excess or obsolescence and considers factors such as historical usage rates and demand.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost less accumulated depreciation. Property and equipment obtained through business combinations are stated at estimated fair value as of the acquisition date. Expenditures for improvements are capitalized, while the costs of maintenance and repairs are charged to operating expense as incurred. Gains and losses related to the sale of property and equipment are recorded in selling, general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income. Depreciation expense for property and equipment of U.S. subsidiaries is determined using the straight-line method over the estimated useful lives of the various asset classes. The estimated useful lives of property and equipment are as follows: Buildings 25 - 39 years Furniture, fixtures and automobiles 3 - 5 years Computer hardware and software 3 - 5 years Warehouse, delivery equipment and tools 3 - 10 years Leasehold improvements Shorter of estimated useful life or lease term Depreciation expense for property and equipment of Canadian subsidiaries is recognized over the estimated useful lives of the various asset classes as follows: Vehicles and trucks 30% - 40% declining balance Furniture and fixtures 8% - 20% declining balance Buildings 4% declining balance Machinery and equipment 30% declining balance Leasehold improvements Straight-line over shorter of estimated useful life or lease term
Goodwill	Goodwill Goodwill is the excess of the consideration transferred over the fair value of identifiable net assets acquired in business combinations accounted for under the acquisition method of accounting. The Company does not amortize goodwill. The Company tests its goodwill annually during the fourth quarter of its fiscal year or when events and circumstances indicate goodwill might be impaired. Impairment testing of goodwill is required at the reporting unit level (operating segment or one level below operating segment). The Company may make a qualitative assessment of the likelihood of goodwill impairment to determine whether a detailed quantitative analysis is required. The quantitative impairment test involves comparing the estimated fair values of the Company’s reporting units with the reporting units’ carrying amounts, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, a goodwill impairment loss is measured as the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill.
Intangible Assets	Intangible Assets Intangible assets consist of customer relationships, trade names and other assets acquired in conjunction with the purchases of businesses or purchases of assets from other companies. The Company typically uses an income method to estimate the acquisition date fair value of intangible assets obtained through a business combination, which is based on forecasts of the expected future cash flows attributable to the respective assets. When management determines material intangible assets are acquired in conjunction with the purchase of a business, the Company determines the fair values of the identifiable intangible assets by considering management’s own analysis and an independent third-party valuation specialist’s appraisal. Intangible assets determined to have definite lives are amortized over their estimated useful lives. Intangible assets determined to have indefinite lives are tested for impairment annually during the fourth quarter of the Company's fiscal year or when events and circumstances indicate that it is more likely than not that the asset is impaired.
Long-Lived Assets	Long-Lived Assets The Company evaluates the recoverability of long-lived assets, including property and equipment, operating lease right-of-use ("ROU") assets and definite-lived intangible assets, for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used or a significant adverse change that would indicate the carrying amount of an asset or group of assets is not recoverable. For long-lived assets to be held and used, the Company recognizes an impairment loss if the carrying amount is not recoverable through the undiscounted cash flows and measures an impairment loss, if any, based on the difference between the carrying amount and fair value. Long-lived assets held for sale are reported at the lower of cost or fair value less costs to sell and are recorded within prepaid expenses and other current assets in the Consolidated Balance Sheets. The Company classifies assets as held for sale if it commits to a plan to sell the asset within one year and actively markets the asset in its current condition for a price that is reasonable in comparison to its estimated fair value.
Leases	Leases The Company leases certain facilities, distribution and warehouse equipment and fleet of vehicles. The Company’s leases have lease terms ranging from one one The Company determines if an arrangement is a lease at inception and evaluates whether the lease meets the classification criteria of a finance or operating lease. Operating leases are included in operating lease right-of-use assets, current portion of operating lease liabilities and long-term operating lease liabilities in the Consolidated Balance Sheets. Finance leases are included in property and equipment, current portion of long-term debt long-term debt Lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of the future lease payments over the lease term. If readily determinable, the rate implicit in the lease is used to discount lease payments to present value. For leases in which the implicit rate is not readily determinable, the Company uses its incremental borrowing rate in determining the present value of future payments. The Company determines its incremental borrowing rate based on the applicable lease terms and the current economic environment. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments. Lease ROU assets also include any lease payments made in advance and exclude lease incentives and initial direct costs incurred. Some of the Company’s lease agreements contain rent escalation clauses (including index-based escalations), rent holidays, capital improvements funding or other lease concessions. Lease expense is recognized on a straight-line basis based on the fixed component over the lease term. Reductions in ROU assets and changes in lease liabilities are presented on a net basis within other non-current assets and liabilities within the operating section of the Company's Consolidated Statement of Cash Flows. Variable lease costs consist primarily of taxes, insurance and common area or other maintenance costs for leased facilities and vehicles and equipment, which are expensed as incurred. The Company also made the accounting policy election to not separate lease components from non-lease components related to its fleet of vehicles.
Insurance Liabilities	Insurance Liabilities The Company is self-insured for certain losses related to medical claims. The Company has stop-loss coverage to limit the exposure arising from medical claims. In addition, the Company has deductible-based insurance policies for certain losses related to general liability, automobile and workers’ compensation. The expected ultimate cost for claims incurred as of the balance sheet date is not discounted and is recognized as a liability if probable and estimable. Insurance losses for claims filed and claims incurred but not reported are accrued based upon estimates of the aggregate liability for uninsured claims using historical loss development factors and actuarial assumptions followed in the insurance industry.
Restructuring	Restructuring The Company recognizes a liability for costs associated with an exit or disposal activity when the liability is incurred. After the appropriate level of management approves the detailed restructuring plan and the criteria for recognition are met, the Company establishes accruals for employee termination and other costs, as applicable. Restructuring costs are classified within selling, general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income.
Debt Issuance Costs	Debt Issuance Costs The Company defers debt issuance costs and amortizes them over the term of the related debt. The Company uses the straight-line method to amortize debt issuance costs for its revolving credit facilities and uses the effective interest method to amortize debt issuance costs for its other debt facilities. Amortization of debt issuance costs is recorded in interest expense in the Consolidated Statements of Operations and Comprehensive Income. The Company classifies debt issuance costs for its revolving credit facilities as an asset in the Consolidated Balance Sheets and classifies debt issuance costs for its other debt facilities as a reduction of the related debt in the Consolidated Balance Sheets.
Stock Appreciation Rights, Deferred Compensation and Liabilities to Noncontrolling Interest Holders	Stock Appreciation Rights, Deferred Compensation and Liabilities to Noncontrolling Interest Holders
Derivative Instruments	Derivative Instruments
Revenue Recognition	Revenue Recognition General. Revenue is recognized upon transfer of control of promised goods to customers at an amount that reflects the consideration the Company expects to receive in exchange for those goods. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. The Company includes shipping and handling costs billed to customers in net sales. These costs are recognized as a component of selling, general and administrative expenses. See Note 16, “Segments,” for information regarding disaggregation of revenue, including revenue by product and by geographic area. Performance Obligations. The Company satisfies its performance obligations at a point in time, which is upon delivery of products. The Company’s payment terms vary by the type and location of its customers. The amount of time between point of sale and when payment is due is not significant and the Company has determined its contracts do not include a significant financing component. The Company’s contracts with customers involve performance obligations that are one year or less. Therefore, the Company applied the standard’s optional exemption that permits the omission of information about its unfulfilled performance obligations as of the balance sheet dates. Significant Judgments. The Company’s contracts may include terms that could cause variability in the transaction price, including customer rebates, returns and cash discounts for prompt payment. Variable consideration is estimated and included in the transaction price based on the expected value method. These estimates are based on historical experience, anticipated performance and other factors known at the time. The Company only includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved.
Cost of Sales	Cost of Sales Cost of sales reflects the direct cost of goods purchased from third parties, rebates earned from vendors, adjustments for inventory reserves and the cost of inbound freight.
Vendor Rebates	Vendor Rebates Typical arrangements with vendors provide for the Company to receive a rebate of a specified amount after it achieves any of a number of measures generally related to the volume of the Company's purchases over a period of time. The Company records these rebates to effectively reduce its cost of sales in the period in which the Company sells the product. Throughout the year, the Company estimates the amount of rebates receivable for the periodic programs based upon the expected level of purchases. The Company accrues for the receipt of vendor rebates based on purchases and reduces inventory to reflect the deferral of cost of sales.
Selling, General, and Administrative Expenses	Selling, General and Administrative Expenses
Advertising Expense	Advertising Expense
Equity Based Compensation	Equity-Based Compensation
Income Taxes	Income Taxes Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized based on the difference between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Inherent in the measurement of deferred balances are certain judgments and interpretations of existing tax law and published guidance as applicable to our operations. The Company evaluates its deferred tax assets to determine if valuation allowances are required. In assessing the realizability of deferred tax assets, we consider both positive and negative evidence in determining whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The primary negative evidence considered includes the cumulative operating losses generated in prior periods. The primary positive evidence considered includes the reversal of deferred tax liabilities related to depreciation and amortization that would occur within the same jurisdiction and during the carry-forward period necessary to absorb the federal and state net operating losses and other deferred tax assets. The reversal of such liabilities supports the realizability of the federal and state net operating losses and other deferred tax assets. The Company records amounts for uncertain tax positions that management believes are supportable but are potentially subject to successful challenge by the applicable taxing authority. Consequently, changes in our assumptions and judgments could materially affect amounts recognized related to income tax uncertainties and may affect our results of operations or financial position. We believe our assumptions for estimates are reasonable, although actual results may have a positive or negative material impact on the balances of such tax positions. Historically, the variation of estimates to actual results is not significant and material variation is not expected in the future.
Concentrations of Risk	Concentrations of Risk Credit Risk. Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents and trade accounts and notes receivable. The Company assesses the credit standing of counterparties as considered necessary. The Company routinely assesses the financial strength of its customers and generally does not require collateral. Concentrations of credit risk with respect to trade accounts receivable are limited due to the substantial number of geographically diverse customers comprising the Company’s customer base. Additionally, the Company maintains allowances for expected credit losses. The Company does not enter into financial instruments for trading or speculative purposes. As of April 30, 2024 and 2023, no customer accounted for more than 10% of gross accounts receivable. Supply Risk. The Company purchases most of its inventories from a select group of vendors. Without these vendors, the Company’s ability to acquire inventory would be significantly impaired.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Authoritative guidance for fair value measurements establishes a three-level hierarchy that prioritizes the inputs to valuation models based upon the degree to which they are observable. The three levels of the fair value measurement hierarchy are as follows: Level 1 Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. Level 2 Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 Inputs are unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions.
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of outstanding shares of common stock for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock, including stock options and restricted stock units (collectively “Common Stock Equivalents”), were exercised or converted into common stock. The dilutive effect of outstanding stock options and restricted stock units is reflected in diluted earnings per share by application of the treasury stock method. In applying the treasury stock method for stock-based compensation arrangements, the assumed proceeds are computed as the sum of the amount the employee must pay upon exercise and the amount of compensation cost attributed to future services and not yet recognized. Diluted earnings per share is computed by increasing the weighted-average number of outstanding shares of common stock computed in basic earnings per share to include the dilutive effect of Common Stock Equivalents for the period. In periods of net loss, the number of shares used to calculate diluted loss per share is the same as basic net loss per share.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Segment Reporting . In November 2023, the Financial Accounting Standards Board ("FASB") issued new guidance to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses regularly provided to the chief operating decision maker ("CODM"). The new guidance is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. The new guidance will apply retrospectively to all periods presented. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements. Income Taxes. In December 2023, the FASB issued new guidance t o enhance income tax disclosures, primarily through changes in the rate reconciliation and income taxes paid disclosures . The new guidance is effective for fiscal years beginning after December 15, 2024. The new guidance will apply on a prospective basis to annual financial statements for periods beginning after the effective date. However, retrospective application in all prior periods presented is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.
