The Company’s services and capabilities allow for integration with customers and form part of their sourcing and procurement function. Substantially all of the Company’s long-lived assets are located within the U.S.

Core & Main is a holding company that indirectly owns Core & Main LP through its ownership interest in Core & Main Holdings, LP (“Holdings”). Core & Main’s primary material assets are its direct and indirect ownership interest in Holdings and deferred tax assets associated with such ownership.

Repurchase Program

On June 12, 2024, the Company’s board of directors authorized a share repurchase program (the “Repurchase Program”), pursuant to which the Company may purchase up to $500 million of the Company’s Class A common stock. Shares repurchased under the Repurchase Program are retired immediately and are accounted for as a decrease to stockholders’ equity. For the three months ended May 4, 2025, the Company repurchased 837,268 shares of Class A common stock for a total of $39 million through open market transactions. As of May 4, 2025, $285 million of the authorized amount remained available for use under the Repurchase Program.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements present the results of operations, financial position and cash flows of Core & Main and its subsidiaries, which includes the consolidated financial statements of Holdings and its consolidated subsidiary, Core & Main LP, as the legal entity that conducts the operations of the Company. All intercompany balances and transactions have been eliminated in consolidation. The limited partner interests of Holdings (“Partnership Interests”) not held by Core & Main are reflected as non-controlling interests in the consolidated financial statements.

In management’s opinion, the unaudited condensed consolidated financial information for the interim periods presented include all normal recurring adjustments necessary for a fair statement of the Company's results of operations, financial position and cash flows, which include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”). Revenues, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim unaudited condensed consolidated financial statements may not be the same as those for the full year. The February 2, 2025 condensed consolidated Balance Sheet was derived from audited financial statements as of that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the fiscal year ended February 2, 2025 included in our Annual Report on Form 10-K for the fiscal year ended February 2, 2025 (the “2024 Annual Report on Form 10-K”).

Segments

The Company’s chief operating decision maker (“CODM”) is the Chief Executive Officer. The CODM manages the business as a single operating and reportable segment. The Company operates approximately 370 branch locations across the U.S. The nature of the products and services, suppliers, customers and distribution methods are similar across branches. The consolidated performance of the Company is utilized to determine incentive compensation for executive officers, annual merit decisions, management of national supplier relationships, allocation of resources and in evaluating acquisitions and the Company’s capital structure. Performance is most notably measured by the CODM based on net sales and net income at the consolidated level, as reported in the consolidated statement of operations. Significant expenses within net income include cost of sales and selling, general and administrative expense, which are each separately presented in the consolidated statement of operations. Other segment items within net income include depreciation and amortization expense, interest expense and income tax expense.

Fiscal Year

The Company’s fiscal year is a 52- or 53-week period ending on the Sunday nearest to January 31 st. Quarters within the fiscal year include 13-week periods, unless a fiscal year includes a 53 rd week, in which case the fourth quarter of the fiscal year will be a 14-week period. Each of the three months ended May 4, 2025 and three months ended April 28, 2024 included 13 weeks. The current fiscal year ending February 1, 2026 (“fiscal 2025”) will include 52 weeks.

Estimates

Management has made a number of estimates and assumptions relating to the reporting of certain assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses in preparing the elements of these financial statements in conformity with U.S. GAAP. Actual results could differ from these estimates.

Accounting Policies

The Company’s significant accounting policies are discussed in Note 2 to the audited consolidated financial statements in our 2024 Annual Report on Form 10-K. There have been no significant changes to these policies which have had a material impact on the Company’s unaudited condensed consolidated financial statements and related notes during the three months ended May 4, 2025.

2)RECENT ACCOUNTING PRONOUNCEMENTS

Income Tax Disclosures- In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). The new guidance requires, on an annual basis, disclosure of specific categories in the rate reconciliation and disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. The adoption of ASU 2023-09 is expected to result in additional disclosures, but not have a material impact on the consolidated financial statements.

Disaggregation of Income Statement Expenses- In November 2024, the FASB issued ASU No. 2024-03, “Disaggregation of Income Statement Expenses” (“ASU 2024-03”). The new guidance requires additional disclosure related to the disaggregation of income statement expense categories. ASU 2024-03 is effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The adoption of ASU 2024-03 is expected to result in additional disclosures and the Company is currently evaluating the effect this standard will have on the consolidated financial statements.

3)REVENUE

Disaggregation of Revenue

The following table represents net sales disaggregated by product category:

4)ACQUISITIONS

The Company did not complete any acquisitions during the three months ended May 4, 2025. The Company made various acquisitions during the three months ended April 28, 2024 (the "Fiscal 2024 Acquisitions") with an aggregate transaction value of $585 million, subject to working capital adjustments, respectively. These transactions were funded with cash and borrowings under the Senior Term Loan Credit Facility (as defined in Note 6).

Fiscal 2024 Acquisitions

•On April 1, 2024, the Company acquired all of the outstanding shares of NW Geosynthetics Inc. (“ACF West”). ACF West hassix locations and is a distributor of geosynthetic products and provider of soil stabilization solutions.

•On March 7, 2024, the Company acquired all of the membership interests of DKC Group Holdings, LLC, and associated entities (collectively, “Dana Kepner”). Dana Kepner hastwenty-one locations and is a distributor of water, wastewater, and storm drainage products.

•On February 12, 2024, the Company acquired certain assets and assumed certain liabilities of Eastern Supply Inc. and a related entity (collectively, “Eastern Supply”). Eastern Supply hastwo locations and is a distributor of a broad range of storm drainage products, with custom fabrication capabilities.

The following table represents the final allocation of the transaction price to the fair value of identifiable assets acquired and liabilities assumed in the Fiscal 2024 Acquisitions.

(1) Amounts include the purchase price allocation of Dana Kepner net assets of $263 million to goodwill, $184 million to intangible assets, $89 million to net working capital, $29 million to cash and $8 million to fixed assets. Additionally, includes a deferred income tax liability of $36 million for the Dana Kepner acquisition.

The net outflow of cash in respect of the purchase of businesses is as follows:

In the above transactions, to the extent applicable, the excess of purchase price over net tangible and intangible assets acquired resulted in goodwill, which represents the assembled workforce and anticipated long-term growth in new markets, customers and products. Goodwill of $195 million associated with the Fiscal 2024 Acquisitions is fully deductible by the Company for U.S. income tax purposes.

Intangible Assets

For the Fiscal 2024 Acquisitions, the intangible assets acquired consist of customer relationships and other intangible assets.

The customer relationship intangible assets represent the value associated with those customer relationships in place at the date of each transaction included in the Fiscal 2024 Acquisitions. The Company valued the customer relationships using an excess earnings method including various inputs such as customer attrition rate, revenue growth rate, gross margin percentage and discount rate. Cash flows associated with the existing relationships are expected to diminish over time due to customer turnover. The Company reflected this expected diminishing cash flow through the utilization of an annual customer attrition rate assumption and in its method of amortization.

The other intangible assets primarily consist of trademark intangible assets that represent the value associated with the brand names in place at the date of the applicable closing.

A summary of the intangible asset acquired and assumptions utilized in the valuation for the Fiscal 2024 Acquisitions is as follows:

(1) Customer relationships acquired and assumptions utilized in the valuation for the Dana Kepner acquisition were as follows: $181 million customer relationship intangible asset,10 years amortization period,13.0% discount rate and 12.5% attrition rate.

Pro Forma Financial Information

The following pro forma information presents a summary of the results of operations for the periods indicated as if the Dana Kepner acquisition had been completed as of January 30, 2023. The pro forma financial information is based on the historical financial information for the Company and Dana Kepner, along with certain pro forma adjustments. These pro forma adjustments consist primarily of:

•increased amortization and depreciation expense related to the intangible assets and fixed assets acquired, respectively, in the Dana Kepner acquisition;

•increased interest expense to reflect the borrowings under the Senior Term Loan Credit Facility including the interest and amortization of deferred financing costs;

•reclassification of direct acquisition transaction costs, retention bonuses and inventory fair value adjustments from the period incurred to periods these expenses would have been recognized given the assumed transaction date identified above; and

•the related income tax effects of the aforementioned adjustments to the provision for income taxes for Core & Main.

The following pro forma information has been prepared for comparative purposes only and is not necessarily indicative of the results of operations as they would have been had the Dana Kepner acquisition occurred on the assumed date, nor is it necessarily an indication of future operating results. In addition, the pro forma information does not reflect the cost of any integration activities, benefits from any synergies that may be derived from the Dana Kepner acquisition or revenue growth that may be anticipated.

As a result of integration of the Dana Kepner acquisition with existing operations of the Company it is impracticable to identify the discrete financial performance associated with the Dana Kepner acquisition. As such, the Company has not presented the post-acquisition net sales and net income for the Dana Kepner acquisition.

5)GOODWILL AND INTANGIBLE ASSETS

Goodwill

The changes in the carrying amount of goodwill are as follows:

Goodwill adjusted during the three months ended May 4, 2025 was related to the Fiscal 2024 acquisitions, as further discussed in Note 4.

Goodwill represents the excess of purchase price over the fair value of net assets acquired. The Company does not amortize goodwill but does assess the recoverability of goodwill on an annual basis during the fourth quarter. If an event occurs or circumstances change that would “more likely than not” reduce the fair value of a reporting unit below its carrying value, an interim impairment test would be performed between annual tests.

Intangible Assets

The Company’s intangible assets included in its Balance Sheets consist of the following:

Amortization expense related to intangible assets was as follows:

The estimated aggregate amortization expense on intangible assets owned by the Company for the remainder of fiscal 2025 and the next four full fiscal years is expected to be as follows:

6)DEBT

Debt consisted of the following:

The Company’s debt obligations as of May 4, 2025 include the following debt agreements:

Senior Term Loan Credit Facility

Core & Main LP has entered into a Senior Term Loan Credit Facility (as defined herein) under which it can incur tranches of indebtedness. Pursuant to the Senior Term Loan Credit Facility, Core & Main LP entered into a $1,500 million senior term loan (the “2028 Senior Term Loan”), which matures on July 27, 2028. The 2028 Senior Term Loan requires quarterly principal payments on the last business day of each fiscal quarter in an amount equal to approximately 0.25% of the original principal amount. The remaining balance is payable upon final maturity of the 2028 Senior Term Loan on July 27, 2028. The 2028 Senior Term Loan bears interest at a rate equal to (i) term secured overnight financing rate (“Term SOFR”) plus, in each case, an effective applicable margin of 2.00% or (ii) the base rate, which will be the highest of (x) the corporate base rate established by the administrative agent as its prime rate in effect at its principal office in New York City from time to time, (y) the overnight federal funds rate plus 0.50% per annum and (z) one-month Term SOFR (adjusted for maximum reserves) plus 1.00% per annum, plus, in each case, an applicable margin of 1.50%. The 2028 Senior Term Loan is subject to a Term SOFR “floor” of 0.00%. The weighted average interest rate, excluding the effect of the interest rate swap, of Core & Main LP’s outstanding borrowings under the 2028 Senior Term Loan as of May 4, 2025 was 6.27%. See further discussion of the interest rate swap below. Based on quotes from financial institutions (i.e., level 2 of the fair value hierarchy), the fair value of the 2028 Senior Term Loan was $1,237 millionas of May 4, 2025.

Pursuant to the Senior Term Loan Credit Facility, Core & Main LP also entered into an additional $944 million senior term loan (the “2031 Senior Term Loan” and, together with the 2028 Senior Term Loan, the “Senior Term Loan Credit Facility”), which matures on February 9, 2031. The 2031 Senior Term Loan requires quarterly principal payments, payable on the last business day of each fiscal quarter, in an amount equal to approximately 0.25% of the principal amount of the 2031 Senior Term Loan. The remaining balance is payable upon final maturity of the 2031 Senior Term Loan on February 9, 2031. The 2031 Senior Term Loan bears interest at a rate equal to (i) Term SOFR plus, in each case, an applicable margin of 2.00% or (ii) an alternate base rate plus an applicable margin of 1.00%. The 2031 Senior Term Loan is subject to a Term SOFR “floor” of 0.00%. The weighted average interest rate, excluding the effect of the interest rate swap, of Core & Main LP’s outstanding borrowings under the 2031 Senior Term Loan as of May 4, 2025 was 6.27%. See further discussion of the interest rate swap below. Based on quotes from financial institutions (i.e., level 2 of the fair value hierarchy), the fair value of the 2031 Senior Term Loanwas $938 millionas of May 4, 2025.

Asset-Based Credit Facility

Core & Main LP has a senior asset-based revolving credit facility with a borrowing capacity of up to $1,250 million, subject to borrowing base availability, with a maturity date of February 9, 2029 (the “Senior ABL Credit Facility”). Borrowings under the Senior ABL Credit Facility bear interest at either a Term SOFR rate plus an applicable margin ranging from 1.25% to 1.75%, or an alternate base rate plus an applicable margin ranging from 0.25% to 0.75%, depending on the borrowing capacity under the Senior ABL Credit Facility. Additionally, Core & Main LP pays a fee of 0.25% on unfunded commitments under the Senior ABL Credit Facility. As of May 4, 2025 and February 2, 2025 there was $100 million and $93 million outstanding, respectively, under the Senior ABL Credit Facility with a weighted average interest rate of 5.57% as of May 4, 2025.

The aforementioned debt agreements include customary affirmative and negative covenants, which include, among other things, restrictions on Core & Main LP’s ability to make distributions, pay dividends, create liens, incur additional indebtedness, make investments, dispose of assets and merge or consolidate with any other person. The Senior Term Loan Credit Facility may require accelerated repayment based upon cash flows generated in excess of operating and investing requirements when the Consolidated Secured Leverage Ratio (as defined in the agreement governing the Senior Term Loan Credit Facility) is greater than or equal to 3.25. In addition, the Senior ABL Credit Facility requires Core & Main LP to comply with a consolidated fixed charge coverage ratio of greater than or equal to 1.00 when availability under the Senior ABL Credit Facility is less than 10.0% of the lesser of (i) the then applicable borrowing base or (ii) the then aggregate effective commitments. The Company was in compliance with all debt covenants as of May 4, 2025.

Substantially all of Core & Main LP’s assets are pledged as collateral for the Senior Term Loan Credit Facility and the Senior ABL Credit Facility.

The aggregate amount of debt payments for the remainder of fiscal 2025 and the next four full fiscal years are as follows:

Interest Rate Swaps

Core & Main LP entered into an instrument in which it makes payments to a third party based upon a fixed interest rate of 0.693% and receives payments based upon the one-month Term SOFR rate. The interest rate swap has a notional amount of $800 million as of May 4, 2025. The notional amount decreases to $700 million on July 27, 2025 through the instrument maturity on July 27, 2026. This instrument is intended to reduce the Company's exposure to variable interest rates under the Senior Term Loan Credit Facility. As of May 4, 2025, this instrument resulted in an effective fixed rate of 2.693%, based upon the 0.693% fixed rate plus an effective applicable margin of 2.00%.

Core & Main LP entered into an additional instrument pursuant to which it will make payments to a third party based upon a fixed interest rate of 3.913% and receive payments based upon the one-month Term SOFR rate. The interest rate swap has a starting notional amount of $750 million that increases to $1,500 million on July 27, 2026 through the instrument maturity on July 27, 2028. The instrument is intended to reduce the Company’s exposure to variable interest rates under the Senior Term Loan Credit Facility. As of May 4, 2025, this instrument resulted in an effective fixed rate of 5.913%, based upon the 3.913% fixed rate plus an effective applicable margin of 2.00%.

The fair value of these cash flow interest rate swaps was a $28 million asset and a $17 million liability as of May 4, 2025, which is included within other assets and other current liabilities, respectively, in the Balance Sheet. The aggregate fair value of these cash flow interest rate swaps was a $40 million asset as of February 2, 2025, which is included within other assets in the Balance Sheet.

The cash flows related to settlement of the interest rate swaps are classified in the consolidated statements of cash flows based on the nature of the underlying hedged items. Fair value is based upon the present value of future cash flows under the terms of the contract and observable market inputs (level 2). Significant inputs used in determining fair value include forward-looking one-month Term SOFR rates and the discount rate applied to projected cash flows.

As of May 4, 2025, the Company estimates $23 million of the cash flow interest rate swap gains will be reclassified from accumulated other comprehensive income into earnings over the next 12 months.

7)INCOME TAXES

For the three months ended May 4, 2025 and April 28, 2024, the Company's effective tax rate was 25.5% and 24.6%, respectively. The effective tax rate for the three months ended May 4, 2025 increased primarily due to a decrease in the non-controlling interest ownership that increased the allocation of net income to taxable entities.

Tax Receivable Agreements

The Company is party to a tax receivable agreement with certain stockholders affiliated with Clayton, Dublier & Rice (“CD&R”) that transferred all of their Partnership Interests at the time of the initial public offering (the “Former Limited Partners Tax Receivable Agreement”) and a tax receivable agreement with certain stockholders affiliated with CD&R and Core & Main Management Feeder, LLC (“Management Feeder”) that continued to own Partnership Interests beyond the time of the initial public offering (the “Continuing Limited Partners Tax Receivable Agreement”) (collectively, the “Tax Receivable Agreements”). The Company has generated tax attributes, and expects to generate additional tax attributes with future exchanges of Partnership Interests, that will reduce amounts that it would otherwise pay in the future to various tax authorities. The Tax Receivable Agreements provide payments to the parties subject to the Tax Receivable Agreements, or their permitted transferees, of 85% of the tax benefits realized by the Company, or in some circumstances are deemed to be realized.

The Company recorded payables to related parties pursuant to the Tax Receivable Agreements of $710 million and $725 million as of May 4, 2025 and February 2, 2025, respectively. Payments under the Tax Receivable Agreements within the next 12 months are expected to be $41 million, whichis included within other current liabilities in the Balance Sheet.

The actual amount and timing of any payments under the Tax Receivable Agreements will vary depending upon a number of factors, including the timing of exchanges by the holders of Partnership Interests, the amount of gain recognized by such holders of Partnership Interests, the amount and timing of the taxable income the Company generates in the future and the federal tax rates then applicable. Assuming (i) that Management Feeder exchanged all of its remaining Partnership Interests at $53.88 per share of our Class A common stock (the closing stock price on May 2, 2025), (ii) no material changes in relevant tax law, (iii) a constant corporate tax rate of 25.1%, which represents a pro forma tax rate that includes a provision for U.S. federal income taxes and assumes the highest statutory rate apportioned to each state and local jurisdiction and (iv) that the Company earns sufficient taxable income in each year to realize on a current basis all tax benefits, the Company would recognize an additional deferred tax asset (subject to offset with existing deferred tax liabilities) of approximately $118 million and a liability of approximately $100 million, payable over the life of the Continuing Limited Partners Tax Receivable Agreement. The full exchange will also decrease Core & Main's aforementioned deferred tax asset associated with its investment in Holdings by $5 million. The foregoing amounts are estimates and subject to change.

8)SUPPLEMENTAL FINANCIAL STATEMENT INFORMATION

Receivables

Receivables consisted of the following:

Accrued Compensation and Benefits

Accrued compensation and benefits consisted of the following:

Leases

The table below presents cash and non-cash impacts associated with leases:

The non-cash impact related to right-of-use assets obtained in exchange for new operating lease liabilities in the table above excludes the impact from acquisitions.

Depreciation Expense

Depreciation expense is classified within cost of sales and depreciation and amortization within the Statement of Operations. Depreciation expense related to property, plant and equipment, including capitalized software, was as follows:

9)NON-CONTROLLING INTERESTS

Core & Main consolidates the consolidated financial statements of Holdings and attributes a portion of net income and equity of Holdings to non-controlling interests related to the vested Partnership Interests held by Management Feeder. The Company had non-controlling interests of 3.8% and 3.9% as of May 4, 2025 and February 2, 2025, respectively.

10)BASIC AND DILUTED EARNINGS PER SHARE

The following table presents the calculation of basic and diluted earnings per share for the three months ended May 4, 2025 and April 28, 2024.

Basic earnings per share is computed by dividing net income attributable to Core & Main for the period by the weighted average number of shares of Class A common stock outstanding during the same period. Shares of Class A common stock issued during the period were weighted for the portion of the period in which the shares of Class A common stock were outstanding. The Company did not apply the two-class method because shares of Class B common stock do not participate in earnings of Core & Main. As a result, the shares of Class B common stock are not considered participating securities and are not included in the weighted average shares outstanding for purposes of basic earnings per share. Net income allocated to holders of non-controlling interests was excluded from net income available to the Class A common stock. There wereno preferred dividends andno shares of preferred stock outstanding for the period.

The diluted earnings per share calculation includes the basic weighted average number of shares of Class A common stock outstanding plus the dilutive impact of potential outstanding shares of Class A common stock that would be issued upon exchange of Partnership Interests, together with the retirement of a corresponding number of shares of Class B common stock, under the if-converted method, if dilutive. The treasury stock method is applied to outstanding awards, including unvested Partnership Interests and outstanding stock appreciation rights, restricted stock units and stock options.

11)RELATED PARTIES

The Company has entered into the Tax Receivable Agreements and the Exchange Agreement, dated as of July 22, 2021 (as amended, the “Exchange Agreement”) with related parties, that are discussed in Note 14 to the audited consolidated financial statements in our 2024 Annual Report on Form 10-K. There have been no significant changes to these related party agreements.

12)SUBSEQUENT EVENTS

Management has evaluated events or transactions that may have occurred that would merit recognition or disclosure in the condensed consolidated financial statements. No subsequent events were identified.
