CORNERSTONE BUILDING BRANDS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in thousands, except share and per share data, unless otherwise noted)

(Unaudited)

Note 1 — Basis of Presentation

Description of Business

Cornerstone Building Brands, Inc. (“Cornerstone Building Brands” or, collectively with its subsidiaries, unless the context requires otherwise, the “Company”) is a holding company incorporated in the State of Delaware. The Company is a leading exterior building products manufacturer by sales in North America and serves residential and commercial customers across new construction and the repair and remodel end markets. The Company is organized in three reportable segments: Aperture Solutions, Surface Solutions and Shelter Solutions.

Basis of Presentation

The accompanying Condensed Consolidated Financial Statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These Condensed Consolidated Financial Statements have been prepared in accordance with the Company's accounting policies and on the same basis as those financial statements included in the Company’s latest Annual Report on Form 10-K for the year ended December 31, 2024, and should be read in conjunction with those Consolidated Financial Statements and the Notes thereto. Certain disclosures normally included in the Company’s Consolidated Financial Statements prepared in accordance with U.S. GAAP have been omitted on a basis consistent with the rules and regulations of the SEC. Certain items have been reclassified in the prior year disclosures to conform to the current year presentation.

The accompanying Condensed Consolidated Financial Statements include the accounts and operations of the Company and its majority-owned subsidiaries and all adjustments (consisting of normal recurring adjustments) that the Company considered necessary to present a fair statement of its results of operations, financial position and cash flows. All significant intercompany accounts and transactions have been eliminated in consolidation.

Note 2 — Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, net sales and expenses and related disclosures of contingent assets and liabilities in the Condensed Consolidated Financial Statements and accompanying notes. These estimates include, but are not limited to: establishing the allowance for expected credit losses; allowance for slow moving and obsolete inventory; the valuation of goodwill; establishing useful lives for and evaluating the recovery of our finite-life, long-lived assets; recognizing the fair value of assets acquired and liabilities assumed in business combinations; determining the fair value of contingent consideration; accounting for rebates and product warranties; the valuation and expensing for share-based compensation; certain assumptions made in accounting for pension benefits; accounting for contingencies and uncertainties; and accounting for income taxes. Actual results may differ from the estimates used in preparing the Condensed Consolidated Financial Statements.

Cash and Cash Equivalents

Cash and cash equivalents mainly consist of highly liquid, unrestricted savings, checking, money market funds with original maturities of less than three months and other bank accounts.

6

Accounts Receivable, Net

The Company reports accounts receivable net of an allowance for expected credit losses. The Company establishes provisions for expected credit losses based on the Company’s assessment of the collectability of amounts owed to the Company by its customers. Such allowances are included in selling, general and administrative expenses in the Company’s Condensed Consolidated Statements of Loss. In establishing the allowance, the Company considers changes in the financial position of a customer, age of the accounts receivable balances, availability of security, unusual macroeconomic conditions, lien rights and bond rights as well as disputes, if any, with its customers. Uncollectible accounts are written off when a settlement is reached for an amount that is less than the outstanding historical balance, all collection efforts have been exhausted or any legal action taken by the Company has concluded. The Company’s allowance for expected credit losses was $20.0 million and $26.3 million at March 29, 2025 and December 31, 2024, respectively.

Business Combinations

We account for business combinations under the acquisition method of accounting, which requires an allocation of the consideration we paid to the identifiable assets, intangible assets and liabilities based on the estimated fair values as of the closing date of the acquisition. The excess of the fair value of the purchase price over the fair values of these identifiable assets, intangible assets and liabilities is recorded as goodwill.

Purchased intangibles other than goodwill are initially recognized at fair value and amortized over their useful lives unless those lives are determined to be indefinite. The valuation of acquired assets will impact future operating results. The fair value of identifiable intangible assets is determined using an income approach on an individual asset basis. Specifically, we use the multi-period excess earnings method to determine the fair value of customer relationships and the relief-from-royalty approach to determine the fair value of trade names. Determining the fair value of acquired intangibles involves significant estimates and assumptions, including forecasted revenue growth rates, margins, percentage of revenue attributable to the trade name, contributory asset charges, customer attrition rate, market-participant discount rates, the assumed royalty rates and income tax rates.

The determination of the useful life of an intangible asset other than goodwill is based on factors including historical trade name performance with respect to consumer name recognition, geographic market presence, market share, plans for ongoing trade name support and promotion, customer attrition rate, and other relevant factors.

The initial purchase price allocation is based upon provisional information and is subject to revision during the measurement period (up to one year from the acquisition date) as additional information concerning valuations is obtained. As the Company obtains new information regarding facts and circumstances that existed as of the acquisition date that, if known, would have resulted in revised estimated values of those assets or liabilities, the Company will accordingly revise the provisional purchase price allocation. These adjustments may include, but are not limited to, adjustments pertaining to intangible assets acquired, property, plant and equipment acquired and tax liabilities assumed.

Recent Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. The new guidance requires consistent categorization and greater disaggregation of information in the rate reconciliation, as well as further disaggregation of income taxes paid. This change is effective for annual periods beginning after December 15, 2024. Prospective application is required, with retrospective application permitted. The Company is currently evaluating the effect the updated guidance will have on its financial statement disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement- Reporting Comprehensive Income- Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which improves disclosure requirements and provides more detailed information about an entity’s expenses, specifically amounts related to purchases of inventory, employee compensation, depreciation, intangible asset amortization and selling expenses, along with qualitative descriptions of certain other types of expenses. This change is effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the effect the updated guidance will have on its financial statement disclosures.

Note 3 — Acquisitions

All purchase price allocations for acquired entities are based upon provisional information and are subject to revision during the measurement period (up to one year from the acquisition date) as additional information is obtained.

Acquisition of Mueller Supply Company, Inc.

In July 2024, the Company completed the acquisition of Mueller Supply Company, Inc. (“Mueller”) for a purchase price of $495.9 million, including a base purchase price of $475.0 million, in addition to closing date cash and working capital adjustments. Mueller is a leading manufacturer of residential metal roofing and components and steel buildings in Texas and the Southwest United States (“U.S.”). Mueller has approximately 900 employees and a comprehensive regional footprint including 38 retail branches and five manufacturing sites in Amarillo, Ballinger and Huntsville, Texas; Oak Grove, Louisiana; and Phoenix, Arizona. This acquisition was funded through issuing long-term debt further discussed in Note 7. Mueller is included in the Company’s Shelter Solutions reportable segment.

The following table summarizes the provisional fair value of net assets acquired:

	Fair Value
Cash and cash equivalent	$	18,074
Accounts receivable	10,346
Inventories	126,516
Property, plant and equipment	207,912
Goodwill	107,543
Trade name and customer relationship intangibles	108,000
Equity investment	11,000
Other assets	5,803
Total assets acquired	595,194
Accounts payable and other liabilities assumed	8,805
Employee related liabilities	5,876
Rebates and customer related liabilities	16,698
Deferred income tax liabilities	67,924
Total liabilities assumed	99,303
Net assets acquired	$	495,891

During the three months ended March 29, 2025, the Company recognized a $3.1 million increase in accounts payable and other liabilities assumed and a corresponding decrease of $3.1 million in employee related liabilities. The Company recorded these measurement period adjustments to update the allocation of the purchase price based upon further analysis of information subsequent to the acquisition date. These adjustments did not have a material impact on the Company’s Condensed Consolidated Statements of Loss for the three months ended March 29, 2025.

As part of the Mueller transaction, the Company acquired a 33.33% interest in BDM Metal Coaters, LLC (“BDM”). The general purpose of BDM is the establishment and operation of a processing facility for the slitting and coating of hot roll steel coils. The Company possesses the ability to exercise significant influence, but not control, over the operating and financial policies of BDM; therefore, the Company accounts for the investment under the equity method of accounting. The carrying value of the investment was $10.7 million as of March 29, 2025 and $11.1 million as of December 31, 2024. The investment in BDM is recognized in other assets, net on our Condensed Consolidated Balance Sheets for both comparable periods.

8

The fair value and expected useful life of identifiable intangible assets consists of the following:

	Fair Value		Useful Life in Years
Customer relationships	$	30,000	11
Trade names and other	78,000		12
Total	$	108,000

The acquisition of Mueller resulted in the recognition of $107.5 million of goodwill. The goodwill recorded is a result of expected synergies and other benefits that we believe will result from the integration of the acquisition within our operations. Goodwill created as a result of the acquisition of Mueller is not expected to be deductible for tax purposes. A net deferred tax liability of $67.9 million was established as a result of the acquisition.

Acquisition of Harvey Building Products Corp.

In April 2024, the Company completed the acquisition of Harvey Building Products Corp. (“Harvey”) for a purchase price of $460.7 million, subject to certain customary adjustments. Harvey is a manufacturer of high performing windows and doors, and its portfolio of industry leading brands include Harvey, Softlite and Thermo-Tech. Headquartered in Waltham, Massachusetts, Harvey has approximately 1,200 employees at four manufacturing facilities located throughout the Northeast and Midwest. Harvey specializes in premium, custom windows and doors primarily serving the Eastern U.S. This acquisition was funded through issuing long-term debt further discussed in Note 7. Harvey is included in the Company’s Aperture Solutions reportable segment.

The following table summarizes the provisional fair value of net assets acquired:

	Fair Value
Cash and cash equivalent	$	10,423
Accounts receivable	27,325
Inventories	21,535
Property, plant and equipment	47,478
Lease right-of-use assets	123,801
Goodwill	173,204
Trade name and customer relationship intangibles	246,000
Other assets	7,375
Total assets acquired	657,141
Accounts payable and other liabilities assumed	36,080
Employee related liabilities	6,208
Lease liabilities	104,807
Deferred income tax liabilities	49,384
Total liabilities assumed	196,479
Net assets acquired	$	460,662

During the three months ended March 29, 2025, the Company recognized a $0.6 million decrease in lease right-of-use assets, a $9.2 million decrease in other assets, $9.2 million decrease in deferred income tax liabilities and a $0.6 million increase in goodwill as a result of these measurement period adjustments. The Company recorded these measurement period adjustments to update the allocation of the purchase price based upon further analysis of information subsequent to the acquisition date. These adjustments did not have a material impact on the Company’s Condensed Consolidated Statements of Loss for the three months ended March 29, 2025.

The fair value and expected useful life of identifiable intangible assets consists of the following:

	Fair Value		Useful Life in Years
Customer relationships	$	200,000	12
Trade names and other	46,000		12
Total	$	246,000

The acquisition of Harvey resulted in the recognition of $173.2 million of goodwill. The goodwill recorded is a result of expected synergies and other benefits that we believe will result from the integration of the acquisition with our operations. Goodwill created as a result of the acquisition of Harvey is not expected to be deductible for tax purposes. A net deferred tax liability of $49.4 million was established as a result of the acquisition.

Contingent Consideration for Acquisition Completed during 2023

In August 2023, the Company completed the acquisition of M.A.C. Métal Architectural Inc. (“MAC Metal”), which became an indirect wholly-owned subsidiary of the Company. Headquartered in Saint-Hubert, Quebec, MAC Metal serves the North American residential and commercial markets with high-end steel siding and roofing products. MAC Metal is included in the Company’s Surface Solutions reportable segment. The total purchase price included earn-out contingent consideration of $16.8 million payable over two consecutive twelve-month periods, with the first period starting in the month following the close of the acquisition and payments are based upon achieving certain adjusted EBITDA-based metrics, as defined in the purchase agreement. There was an increase of $1.0 million in contingent consideration in the three months ended March 29, 2025, including the impact of exchange rates. Total contingent consideration of $22.1 million as of March 29, 2025 and $21.1 million as of December 31, 2024 is recognized in other current liabilities on our Condensed Consolidated Balance Sheets.

Note 4 — Inventories

The carrying amounts of the indebtedness under revolving credit facilities approximate fair value as the interest rates are variable and reflective of market rates.

Issuance of 9.500% Senior Secured Notes due August 2029

On August 7, 2024, the Company issued $500.0 million in aggregate principal amount of 9.500% Senior Secured Notes (“9.500% Senior Secured Notes”) due August 2029 (subject to springing maturity under certain circumstances). Interest is payable semi-annually in arrears on February 15 and August 15 of each year, commencing on February 15, 2025.

The 9.500% Senior Secured Notes are secured senior indebtedness and rank equal in right of payment with all existing and future senior indebtedness of the Company, and are senior in right of payment to all existing and future subordinated indebtedness of the Company.

The Company may redeem the 9.500% Senior Secured Notes in whole or in part, subject to certain prepayment premiums if the 9.500% Senior Secured Notes were to be redeemed prior to August 15, 2028.

Term Loan Facility, due April 2028, Term Loan Facility, due May 2031 and Cash Flow Revolver

In April 2018, Ply Gem Midco entered into a Cash Flow Agreement (as amended from time to time, the “Cash Flow Credit Agreement”); facilities provided thereunder, including the Term Loan Facility, due April 2028, the Term Loan Facility, due May 2031 and the Cash Flow Revolver (each as defined below), the “Cash Flow Facilities”), which provides for (i) a term loan facility (the “Term Loan Facility, due April 2028”) in the aggregate principal amount of $2,600.0 million, issued with a discount of 0.5% and (ii) a cash flow-based revolving credit facility (the “Cash Flow Revolver”) of up to $115.0 million. In connection with the consummation of the Ply Gem merger, the Company and Ply Gem Midco entered into a joinder agreement in which the Company became the Borrower (as defined in the Cash Flow Credit Agreement). On April 11, 2023, the Company amended the Cash Flow Credit Agreement to replace the adjusted LIBOR rate with the Secured Overnight Financing Rate (“SOFR”) rate. On May 15, 2024, the Company entered into a Fifth Amendment to the Cash Flow Credit Agreement (the “Cash Flow Fifth Amendment”) to, among other things, terminate the $92.0 million of commitments under the Cash Flow Revolver and replace such commitments with $92.0 million of extended cash flow-based revolving commitments, maturing on May 15, 2029 (subject to a springing maturity under certain circumstances) and (b) incur a new incremental term loan facility (the “Term Loan Facility, due May 2031”) in the aggregate principal amount of $500.0 million, maturing on May 15, 2031 (subject to a springing maturity under certain circumstances).

The Term Loan Facility, due April 2028 amortizes in nominal quarterly installments equal to one percent of the aggregate initial principal amount thereof per annum, with the remaining balance payable upon final maturity. The Term Loan Facility, due April 2028 bears annual interest at a floating rate measured by reference to, at the Company’s option, either (i) a Term SOFR rate with a credit spread adjustment of 0.10% (subject to a floor of 0.50%) plus an applicable margin of 3.25% per annum or (ii) an alternate base rate plus an applicable margin of 2.25% per annum.

Loans outstanding under the Cash Flow Revolver bear annual interest at a floating rate measured by reference to, at the Company’s option, either (i) a Daily Simple SOFR rate or a Term SOFR rate with (only in the case of Term SOFR rate borrowings with an interest period greater than one month) a credit spread adjustment of 0.10% (subject to a floor of 0.00%) plus an applicable margin ranging from 2.50% to 3.00% per annum depending on the Company’s secured leverage ratio or (ii) an alternate base rate plus an applicable margin ranging from 1.50% to 2.00% per annum depending on the Company’s secured leverage ratio. There are no amortization payments under the Cash Flow Revolver. Additionally, unused commitments under the Cash Flow Revolver are subject to a fee ranging from 0.25% to 0.50% per annum depending on the Company’s secured leverage ratio.

The Term Loan Facility, due May 2031, amortizes in nominal quarterly installments equal to one percent of the aggregate initial principal amount thereof per annum, with the remaining balance payable upon maturity. The Term Loan Facility, due May 2031 bears annual interest at a floating rate measured by reference to, at the Company’s option, either (i) a Term SOFR rate (subject to a floor of 0.50%) plus an applicable margin of 4.50% per annum or (ii) an alternate base rate plus an applicable margin of 3.50% per annum.

Subject to certain exceptions, the Term Loan Facility, due April 2028 and the Term Loan Facility due May 2031 are subject to mandatory prepayments in an amount equal to:

•the net cash proceeds of (i) certain asset sales, (ii) certain debt offerings and (iii) certain insurance recovery and condemnation events; and

•50% of annual excess cash flow (as defined in the Cash Flow Credit Agreement), subject to reduction to 25% and 0% if specified secured leverage ratio targets are met to the extent that the amount of such excess cash flow exceeds $10.0 million. No payments were required in 2022 under the year 2021 excess cash flow calculation.

13

The Term Loan Facility, due April 2028, the Term Loan Facility, due May 2031 and the Cash Flow Revolver may be prepaid at the Company’s option at any time without premium or penalty (other than customary breakage costs), subject to minimum principal amount requirements.

ABL Facility, due May 2029

On April 12, 2018, Ply Gem Midco entered into an ABL Credit Agreement (as amended from time to time, the “ABL Credit Agreement”), which provides for (a) an asset-based revolving credit facility of up to $850.0 million (amended from time to time the “ABL Facility”), a portion of which is (i) available to U.S. borrowers and (ii) available to U.S. and Canadian borrowers. In connection with the consummation of the Ply Gem merger, the Company and Ply Gem Midco entered into a joinder agreement in which the Company became the Parent Borrower (as defined in the ABL Credit Agreement) under the ABL Facility, and (b) a first-in-last-out tranche asset-based revolving credit facility of up to $95.0 million (the “ABL FILO Facility”) available to U.S. borrowers.

On May 15, 2024, the Company entered into Amendment No. 8 to the ABL Credit Agreement (“Amendment No. 8”), which amended the ABL Credit Agreement in order to terminate the existing revolving commitments under the ABL Facility and the ABL FILO Facility originally maturing on July 25, 2027 (the “Existing ABL Commitments”), and replace such Existing ABL Commitments with an extended revolving commitment of $945.0 million maturing on May 15, 2029 (subject to a springing maturity under certain circumstances), subject to the outstanding aggregate principal amount.

Borrowing availability under the ABL Facility and the ABL FILO Facility (collectively, the “ABL Facilities”) is determined by a monthly borrowing base collateral calculation that is based on specified percentages of the value of eligible inventory, accounts receivable, less certain allowances and subject to certain other adjustments as set forth in the ABL Credit Agreement. Availability is reduced by issuance of letters of credit as well as any borrowings.

Loans outstanding under the ABL Facility bear interest at a floating rate measured by reference to, at the Company’s option, either (i) a Term SOFR rate (subject to a SOFR floor of 0.00%) plus an applicable margin ranging from 1.25% to 1.75% per annum depending on the average daily excess availability under the ABL Facility or (ii) an alternate base rate plus an applicable margin ranging from 0.25% to 0.75% per annum depending on the average daily excess availability under the ABL Facility. Additionally, unused commitments under the ABL Facility are subject to a 0.25% per annum fee.

Loans outstanding under the ABL FILO Facility bear interest at a floating rate measured by reference to, at the Company’s option, either (i) a term SOFR rate (subject to a SOFR floor of 0.00%) plus an applicable margin ranging from 2.25% to 2.75% per annum depending on the average daily excess availability under the ABL FILO Facility or (ii) an alternate base rate plus an applicable margin ranging from 1.25% to 1.75% per annum depending on the average daily excess availability under the ABL FILO Facility. Additionally, unused commitments under the ABL FILO Facility are subject to a 0.25% per annum fee.

Covenant Compliance

The ABL Credit Agreement includes a minimum fixed charge coverage ratio of 1.00:1.00, which is tested only when specified availability is less than 10.0% of the lesser of (x) the then applicable borrowing base and (y) the then aggregate effective commitments under the ABL Facility and continuing until such time as specified availability has been in excess of such threshold for a period of 20 consecutive calendar days. The Cash Flow Credit Agreement includes a financial covenant set at a maximum secured leverage ratio of 7.75:1.00, which will apply if the outstanding amount of loans and drawings under letters of credit which have not then been reimbursed exceeds a specified threshold at the end of any fiscal quarter.

The Company’s debt agreements contain a number of covenants that, among other things, limit or restrict the ability of the Company and its subsidiaries to incur additional indebtedness; make dividends and other restricted payments; incur additional liens; consolidate, merge, sell or otherwise dispose of all or substantially all assets; make investments; transfer or sell assets; enter into restrictive agreements; change the nature of the business; and enter into certain transactions with affiliates. The Company is in compliance with all of its covenants as of March 29, 2025.

Interest Rate Swaps

The Company uses certain interest rate swaps to manage a portion of the interest rate risk on its term loans. The following table sets forth the terms of the Company’s interest rate swap agreements:

Notional amount	$	1,500,000
Forecasted term loan interest payments being hedged	1-month SOFR
Fixed rate paid	2.0038%
Origination date	April 17, 2023
Maturity date	April 15, 2026
Fair value at March 29, 2025 - Other assets, net	$	29,427
Fair value at December 31, 2024 - Other assets, net	$	39,159
Level in fair value hierarchy(1)	Level 2

(1)Interest rate swaps are based on cash flow hedge contracts that have fixed rate structures and are measured against market based SOFR yield curves. These interest rate swaps are classified within Level 2 of the fair value hierarchy because they are valued using alternative pricing sources or models that utilized market observable inputs, including current and forward interest rates.

Note 8— Accumulated Other Comprehensive Income (Loss)

The following tables set forth the change in accumulated other comprehensive income (loss) attributable to the Company by each component of accumulated other comprehensive income (loss), net of applicable income taxes:

	Foreign Currency Translation Adjustment		Derivatives, Net of Tax		Pensions, Net of Tax		Total Accumulated Other Comprehensive Income (Loss)
Balance, December 31, 2024	$	(25,092)	$	16,448	$	1,380	$	(7,264)

Balance, March 30, 2024	$	(11,734)	$	34,914	$	820	$	24,000

Note 9 — Share-Based Compensation

Incentive Unit Awards

Beginning in the fourth quarter of 2022, pursuant to an incentive unit grant agreement, certain participants were granted incentive units in Camelot Return Ultimate, LP (the “Partnership” or “Camelot Return Ultimate”), an indirect parent of the Company. The incentive units provide the holder with the opportunity to receive, upon certain vesting events and subject to Partnership repurchase rights and conditions, a return based upon the appreciation of the Partnership’s equity value from the date of grant. The incentive units vest over a five-year period on a straight-line basis. For the three months ended March 29, 2025, 10,400 incentive units were granted at an average grant date fair value of $40.71 per incentive unit. The Company recognized a gain from incentive units of $3.7 million in the three months ended March 29, 2025, due to the reversal of prior expense from terminations, and expense of $1.6 million for the three months ended March 30, 2024. The Company estimates that the unrecognized expense is expected to be recognized over a weighted-average period of 3.0 years totaling $16.0 million.

Note 10 — Equity Transactions

In January 2024, the Company paid a dividend on our common stock in the aggregate amount of $231.6 million, which was received by our direct parent Camelot Return Intermediate Holdings, LLC, (“Camelot Parent”), and further distributed to Camelot Return Parent, LLC (“Camelot Return Parent”), an indirect parent of the Company. Camelot Return Parent used the funds received to redeem all 1,950,000 preferred units of Camelot Return Parent held by CD&R Pisces Holdings, L.P.

15

Note 11 — Income Taxes

The Company’s effective tax rate includes state income taxes, foreign tax rate differentials and changes in the valuation allowance. The following table sets forth the effective tax rate for the three months ended March 29, 2025 and March 30, 2024:

	Three Months Ended
	March 29, 2025		March 30, 2024
Effective tax rate	(18.9)	%	14.9	%

The Company’s effective tax rate varied from the statutory tax rate primarily due to state income taxes, foreign tax rate differentials and changes in the valuation allowance. The change in the effective tax rate for the three months ended March 29, 2025 compared to the three months ended March 30, 2024 is primarily due to the increase in pre-tax book losses and a decrease in long term-compensation related expenses.

Note 12 — Fair Value of Financial Instruments and Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis. 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. The Company uses a three-level hierarchy for fair value measurements based on the observability of inputs to the valuation of an asset or liability as of the measurement date. The three levels of the fair value hierarchy are as follows:

•Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities.

•Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

•Level 3 – Unobservable inputs for the asset or liability, reflecting the Company’s own assumptions about the assumptions that market participants would use in pricing the asset or liability.

Fair Value Measurements on a Recurring Basis

The following table presents the Company’s financial assets and liabilities measured at fair value on a recurring basis as of March 29, 2025:

	Level 1		Level 2		Level 3		Total
Assets – Derivative instruments	$	—	$	29,427	$	—	$	29,427
Liabilities – Contingent consideration	$	—	$	—	$	22,100	$	22,100

The following table presents the Company’s financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2024:

	Level 1		Level 2		Level 3		Total
Assets – Derivative instruments	$	—	$	39,159	$	—	$	39,159
Liabilities – Contingent consideration	$	—	$	—	$	21,122	$	21,122

The fair value for derivative instruments is determined using valuation models that incorporate observable market inputs, such as interest rates and currency exchange rates, and is classified within Level 2 of the fair value hierarchy.

The fair value of contingent consideration is estimated as of the date of the acquisition and is recorded as part of the purchase price, and is subsequently re-measured to fair value at each reporting date, based on a probability-weighted analysis using a rate that reflects the uncertainty surrounding the expected outcomes, which the Company believes is appropriate and representative of market participant assumptions.

Fair Value Measurement Disclosure

The fair value of the Company’s short-term debt is estimated using observable market inputs, including current interest rates for similar types of borrowings. The fair value of long-term debt is determined based on quoted prices for identical or similar

16

instruments in active markets. The fair value of the senior notes is based on quoted prices in active markets for the identical liabilities. The fair value of the term loans is based on recent trading activities of comparable market instruments.

Non-Recurring Fair Value Measurements

Certain assets and liabilities are measured at fair value on a non-recurring basis. These include assets and liabilities that are measured at fair value in the event of impairment or for disclosure purposes. The discounted cash flow method under the income approach is generally employed to estimate the fair value of the reporting units or identified asset groups. For reporting units, the guideline public company method and the guideline transaction method are also utilized under the market approach. Significant assumptions inherent in estimating fair values include the projected future annual net cash flows for each reporting unit, encompassing net sales, cost of sales, selling, general and administrative expenses, depreciation and amortization, working capital, and capital expenditures. Other critical assumptions involve income tax rates, long-term growth rates, and a discount rate that appropriately reflects the risks inherent in each future cash flow stream.

Fair Value of Financial Instruments Not Measured at Fair Value

The carrying amounts of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, and accrued liabilities approximate their fair values due to the short-term nature of these instruments.

Note 13 — Related Party Transactions

The Company had a related party receivable with CD&R of $6.8 million as of March 29, 2025 and $5.7 million as of December 31, 2024, representing legal fees paid on their behalf as part of the ongoing stockholder litigation described in Note 14.

The Company had a related party payable of $6.0 million to our indirect parent, Camelot Return Ultimate, as of March 29, 2025 and December 31, 2024, representing monies paid by Company management for the purchase of incentive units in the Partnership. See Note 9 for further discussion of the incentive units.

Note 14 — Commitments and Contingencies

As a manufacturer of products primarily for use in building construction, the Company is inherently exposed to various types of contingent claims, both asserted and unasserted, in the ordinary course of business. As a result, from time to time, the Company may become involved in various legal proceedings or other contingent matters arising from claims or potential claims arising out of its operations and businesses that cover a wide range of matters, including, among others, environmental, contract, employment, including applicable benefit and pension plans, intellectual property, securities, personal injury, property damage, product liability, warranty and modification, adjustment or replacement of component parts or units sold, which may include product recalls. The Company insures (or self-insures) against these risks to the extent deemed prudent by its management and to the extent insurance is available. Management believes that the ultimate disposition of these matters will not have a material adverse effect on the Company’s results of operations, financial position or cash flows. However, such matters are subject to many uncertainties and outcomes and are not predictable with assurance. The Company believes it is adequately reserved for all matters.

Environmental

The Company’s operations are subject to various federal, state, local and foreign environmental, health and safety laws. Among other things, these laws regulate the emissions or discharge of contaminants into the environment; govern the use, storage, treatment, disposal and management of hazardous substances and wastes; protect employee health and safety, public health and welfare and the end-users of its products; regulate the chemicals used in its products; and impose liability for the costs of investigating and remediating (as well as other damages resulting from) present and past releases of hazardous substances. Violations of these laws or of any conditions contained in environmental permits could impact the Company's current and future operations.

The Company believes it is in material compliance with all applicable laws and regulations and has recorded a liability of $4.1 million as of March 29, 2025 and December 31, 2024 for certain subsurface investigation and remedial matters.

17

Litigation

The Company is a party to a variety of legal actions arising out of the normal course of business. Plaintiffs occasionally seek punitive or exemplary damages. The Company is also included in other kinds of legal actions, some of which assert or may assert claims or seek to impose fines or penalties and other costs in substantial amounts and are described below.

Stockholder Litigation

In July 2022, and pursuant to an Agreement and Plan of Merger dated March 5, 2022 Clayton, Dubilier and Rice, LLC (“CD&R”) became the indirect owner of Cornerstone Building Brands (the “Merger”). In January 2023, purported former stockholders filed 2 separate complaints challenging the fairness of the Merger. The complaints are captioned Firefighters’ Pension System of the City of Kansas City, Missouri Trust and Gary D. Voigt v. Affeldt et al., C.A. No. 2023-0091-JTL (Del. Ch.) and Whitebark Value Partners LP and Robert Garfield v. Clayton Dubilier & Rice, LLC et al., C.A. No. 2023-0092-JTL (Del. Ch.). In both complaints, the plaintiffs allege that CD&R and its affiliates controlled the Company prior to the transaction and that certain directors and officers of the Company, as well as CD&R and its affiliates, breached their fiduciary duties and engaged in conduct resulting in a sale of the Cornerstone Building Brands public stockholders’ shares to CD&R at an unfair price. The plaintiffs seek unspecified monetary damages, attorneys’ fees, expenses and costs. The court consolidated the two cases, and on May 3, 2023, selected Whitebark Value Partners LP as lead plaintiff. On July 14, 2023, the defendants moved to dismiss the operative complaint. The motion to dismiss was denied on January 10, 2024, and the case is ongoing. On June 26, 2024, the plaintiffs filed an amended complaint. On February 24, 2025, the parties to the case filed a Stipulation of Compromise and Settlement (“Stipulation”) setting forth their agreement to settle the litigation. The Stipulation remains subject to court approval. The Stipulation provides for CD&R and the Company, on behalf of the defendants, to pay or cause their respective insurers to pay a total of $45.0 million into an escrow account that will be used to pay escrow expenses, satisfy any fee and incentive amounts awarded by the court in favor of plaintiff and plaintiff’s counsel, and distribute the remaining funds to the non-affiliated shareholders of the Company. The Company's portion of the proposed settlement relating to its indemnification of its former directors and officers is recoverable from insurance. The agreement is contingent upon final court approval, for which a hearing is scheduled on May 29, 2025.

In June 2023, a purported former stockholder filed a class action complaint in the United States District Court for the District of Delaware alleging that the Company’s disclosures issued in connection with the Merger were materially misleading in violation of Section 14(a) and Section 20(a) of the Securities Exchange Act of 1934. The complaint is captioned Water Island Merger Arbitrage Institutional Commingled Master Fund, L.P. v. Cornerstone Building Brands et al., Case No. 1:23-cv-00701 (D. Del.). The complaint alleges that the Company’s directors and officers issued misleading disclosures, which caused stockholders to approve the Merger at an unfair price. The plaintiff seeks unspecified monetary damages, interest, attorney’s fees, expenses and costs. On December 8, 2023, the defendants moved to dismiss the operative complaint, and, in the alternative, to stay in litigation. On September 30, 2024, the court granted the defendants’ motion to dismiss without prejudice.

Note 15 — Reportable Segment and Geographical Information

Operating segments are defined as components of an enterprise for which discrete financial information is available that is evaluated regularly by the chief operating decision maker (“CODM”) for purposes of allocating resources and evaluating financial performance. Our CODM, who is our Chief Executive Officer, reviews financial information presented on a consolidated basis for the purposes of allocating resources and evaluating financial performance. The Company is organized in five operating segments aggregated into three reportable segments: Aperture Solutions (consisting of the Aperture Solutions–U.S. and Aperture Solutions–Canada operating segments), Surface Solutions (consisting of the Surface Solutions–U.S. and Surface Solutions–Canada operating segments) and Shelter Solutions, itself an operating segment. The aggregated reportable segments share similar economic characteristics with respect to product offerings, manufacturing processes, and customer demographics. We operate principally in the U.S. with limited operations in Canada.

•The Aperture Solutions reportable segment offers a broad line of windows and doors at multiple price-points for residential new construction and repair and remodel end markets in the U.S. and Canada. Its main products include vinyl, aluminum, wood-composite and aluminum clad-wood windows and patio doors, as well as steel, wood-composite, and fiberglass entry doors.

18

•The Surface Solutions reportable segment offers a broad suite of surface solutions products and accessories at multiple price-points for the residential new construction and repair and remodel end markets as well as stone installation services. Its main products include vinyl siding and accessories, cellular polyvinyl chloride trim, vinyl fencing and railing, stone veneer and gutter protection products.

•The Shelter Solutions reportable segment designs, engineers, manufactures and distributes extensive lines of metal products for the low-rise commercial construction market under multiple brand names and through a nationwide network of manufacturing plants, distribution centers and retail branches. The Company defines low-rise commercial construction as building applications of up to five stories.

Management monitors the operations results of its operating segments separately for purposes of making decisions about resources and evaluating performance. Management, including the Company’s chief operating decision maker, evaluates performance on the basis of segment earnings before interest, income taxes, depreciation and amortization (“Adjusted reportable segment EBITDA”).

Corporate operating expenses are not allocated to reportable segments. Corporate and Other consists specifically of corporate operating expenses that are generally not allocated to reportable segments, related-party management fees, and other items that are not assigned or allocated to reportable segments. Any intercompany net sales or expenses are eliminated in consolidation.

Company Overview

Our Company

Cornerstone Building Brands, Inc. (“Cornerstone Building Brands”, together with its subsidiaries, unless the context requires otherwise, the “Company,” “we,” “us” or “our”) is a holding company incorporated in the State of Delaware. We are a leading manufacturer of exterior building products in North America by sales and serve residential and commercial customers across both the new construction and repair and remodel markets.

Our operations are organized as three reportable segments: Aperture Solutions, Surface Solutions and Shelter Solutions. We have:

•One of the broadest product offerings in our industry. Our total addressable market is diverse and expands across multiple geographies, end markets, channels and customers providing us with significant benefits.

•A leading market position in various North American markets we serve, including, among others, vinyl windows, vinyl siding, stone veneer installations, metal accessories, metal roofing and wall systems and engineered metal building systems.

•An extensive coast-to-coast network of manufacturing, distribution and branch office facilities throughout North America.

•A vertically integrated manufacturing process that enables us to deliver better service and positions us to be a cost-advantaged manufacturer.

24

We are mindful of the harmful effects of global climate change and the contributions to climate change from manufacturing operations and the end-use of building construction products. We have made and continue to make progress on our work related to sustainability matters.

Tariffs

We are navigating through several external factors that create uncertainty and volatility in our operating environment, including, but not limited to, new tariffs and evolving trade policy. These rapidly changing policies and dynamics pose a risk to our supply chain and cost structure. Any new tariffs and trade restrictions that may be implemented could result in reduced overall economic activity and increased costs in operating our business, which, if unmitigated, could have a material adverse effect on our business, financial condition and results of operations. See Risk Factor “Price volatility and supply constraints for raw materials could prevent us from meeting delivery schedules to our customers or reduce our profit margins” in in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Results of Operations

The following table represents key results of operations on a consolidated basis for the interim periods indicated and the changes between periods:

* Refer to Non-GAAP Financial Measures for further discussion.

Net sales increased $29.6 million, or 2.6%, for the three months ended March 29, 2025, compared to the comparable prior year period, mainly due to the strategic acquisitions of Harvey Building Products Corp. (“Harvey”) in April 2024 and Mueller Supply Company, Inc. (“Mueller”) in July 2024, partially offset by lower volumes across all reportable segments.

Gross profit as a percentage of net sales was 20.1% for the three months ended March 29, 2025, compared to 20.4% for the comparable prior year period, primarily due to lower average selling price and higher materials costs due to inflation.

Selling, general and administrative expenses increased $14.5 million, for the three months ended March 29, 2025 compared to the comparable prior year period. The Company incurred higher employee related expenses and depreciation and amortization during the current year primarily due to the acquisitions of Harvey and Mueller during 2024. These increases are partially offset by sales and incentive compensation related expenses due to reduced volumes, excluding acquisition impacts.

25

Interest expense increased $22.9 million for the three months ended March 29, 2025, compared to the comparable prior year period. The following table sets forth the components of interest expense:

	Three Months Ended
(Amounts in thousands)	March 29, 2025		March 30, 2024
Interest on outstanding borrowings	$	99,712	$	83,928
Cash impact of interest rate swaps	(8,850)		(13,019)
Amortization of interest rate swap fair value(1)	2,962		2,962
Amortization of debt discount, debt issuance costs and purchase accounting fair value adjustment(1)	23,209		20,914
Other	648		35
Total interest expense	$	117,681	$	94,820

(1)The fair value adjustments were made in connection with the Merger in July 2022.

Foreign exchange loss was $0.3 million of losses for the three months ended March 29, 2025 compared to $4.0 million of losses for the three months ended March 30, 2024. The changes period over period are attributable to foreign exchange rate changes on intercompany loans based in Canadian currency.

Other income, net, decreased $2.5 million for the three months ended March 29, 2025, compared to the comparable prior year period, mainly due to less interest income earned on our cash and cash equivalents year over year.

Income tax expense (benefit) was $(25.8) million for the three-month period ended March 29, 2025 compared to $15.3 million for the three-month period ended March 30, 2024. The change was mainly due to an increase in pre-tax book losses during the three months ended March 29, 2025 compared to the three months ended March 30, 2024, in addition to a tax benefit related to deferred compensation during the three months ended March 29, 2025.

(Amounts in thousands)	March 29, 2025		March 30, 2024
Depreciation:
Cost of sales	$	38,903	$	40,932
Selling, general and administrative expenses	11,574		6,151
Total depreciation	50,477		47,083
Amortization — Selling, general and administrative expenses	53,274		47,234
Total depreciation and amortization	$	103,751	$	94,317

Depreciation and amortization increased $9.4 million for the three months ended March 29, 2025 mainly due to the acquisitions of Harvey in April 2024 and Mueller in July 2024.

Liquidity and Capital Resources

Our main liquidity and capital resource needs are payments to service our debt, ongoing operations and working capital requirements, capital expenditures and the cost of acquisitions. Our primary source of liquidity is cash generated from our continuing operations, as well as borrowings under our credit facilities. We believe that funds provided by these sources will be adequate to meet our liquidity and capital resource needs for at least the next 12 months under current operating conditions.

We may from time to time take steps to reduce our debt. These actions may include repurchases or opportunistic refinancing of debt. The amount of debt, if any, that may be repurchased or refinanced will depend on market conditions, trading levels of our debt, our cash position, compliance with debt covenants and other considerations. Our affiliates may also purchase our debt from time to time, through open market purchases or other transactions. In such cases, our debt may not be retired, in which

28

case we would continue to pay interest in accordance with the terms of such debt and we would continue to reflect the debt as outstanding in our Condensed Consolidated Balance Sheets.

The following table sets forth our total net liquidity position as of March 29, 2025:

(Amounts in thousands)	Amount
Cash and cash equivalents	$	162,414
Revolving credit facilities:
Asset-based lending facility(1)	850,000
Cash flow revolving facility	92,000
First-in-last-out tranche asset-based lending facility	95,000
Total revolving credit facilities	1,037,000
Less:
Debt issued under the facilities	265,000
Letters of credit outstanding and priority payables	51,518
Net credit facility	720,482
Net liquidity	$	882,896

(1)    Borrowing availability under the ABL Facilities is determined based on specified percentages of the value of eligible inventory, accounts receivable, less certain allowances and subject to certain other adjustments as set forth in the ABL Credit Agreement. Availability is also reduced by issuance of letters of credit.

In April 2025, the Company borrowed $25.0 million on the ABL Facility.

Cash Flows

	Three Months Ended
(Amounts in thousands)	March 29, 2025		March 30, 2024
Cash flows from operating activities	$	(136,128)	$	(163,697)
Cash flows from investing activities	$	(36,269)	$	(49,668)
Cash flows from financing activities	$	170,000	$	(138,875)

Cash Flows From Operating Activities

Net cash from operating activities consists mainly of: (i) cash collections on credit sales to our customers, (ii) purchases of commodity based raw materials, (iii) labor and other employee-related expenditures, (iv) other non-labor costs, such as, among other items, supplies, insurance, advertising and marketing costs, (v) interest paid on our long-term debt and (vi) payments for income taxes.

Net cash from operating activities was $(136.1) million for the three months ended March 29, 2025, an increase from the $(163.7) million from operations in the prior year. Lower volumes, higher core working capital, consisting of accounts receivable, inventories and accounts payables, were offset by favorable long-term incentive compensation plan adjustments.

Cash Flows From Investing Activities

Our main uses of cash for investing activities are for payments for property and equipment and acquisitions of businesses.

Net cash from investing activities was $(36.3) million for the three months ended March 29, 2025 compared to $(49.7) million from investing activities for the nine months ended March 30, 2024. The $13.4 million increase is mainly driven by reduced spending on capital expenditures during the current year compared to the prior year.

29

Cash Flows From Financing Activities

Our main uses of cash for financing activities include activity to repurchase and make payments on our long-term debt and distributions to our direct parent Camelot Return Intermediate Holdings, LLC, (“Camelot Parent”). Our main sources of cash from financing activities include the proceeds from issuances of debt.

Net cash from financing activities was $170.0 million for the three months ended March 29, 2025 compared to $(138.9) million from financing activities for the three months ended March 30, 2024. The increase of $308.9 million is mainly driven by $70.0 million in additional short-term borrowings during the current year, offset by the dividend payment of $231.6 million made to Camelot Parent during the prior year.

Contingent Liabilities and Commitments

Leases

We have leases for certain manufacturing, warehouse, distribution locations, offices, vehicles and equipment. As of March 29, 2025 the Company had total future lease payments of $678.3 million, with $85.7 million payable within 12 months.

Debt

We have certain debt instruments outstanding. As of March 29, 2025 the Company had total future payments of $5.1 billion, with $42.5 million payable within 12 months. See Note 7 in the Notes to the Condensed Consolidated Financial Statements for additional information.

Non-GAAP Financial Measures

We use several measures derived from consolidated financial information, but not presented in our Condensed Consolidated Financial Statements prepared in accordance with accounting principles generally accepted in the U.S (“U.S. GAAP”). These measures are considered non-GAAP financial measures. Specifically, in this report, we refer to adjusted EBITDA, which is a non-GAAP financial measure. Our non-GAAP financial measure is not intended to replace the presentation of the comparable measure under U.S. GAAP. However, we believe the presentation of the non-GAAP financial measure, when considered together with the comparable U.S. GAAP financial measure, along with a reconciliation to its respective U.S. GAAP financial measure, assists investors in understanding the factors and trends affecting our underlying business that could not be obtained absent these disclosures. Additionally, we believe that the presentation of our non-GAAP financial measure enables investors to evaluate trends in the business excluding certain items which are not entirely a result of our base operations.

Furthermore, the presentation of this non-GAAP financial measure supplements other metrics we use to internally evaluate our business and facilitates the comparison of past and present operations. The non-GAAP financial measure we use may differ from non-GAAP financial measures used by other companies and other companies may not define non-GAAP financial measures we use in the same way.

See Part I, Item 1, “Condensed Consolidated Financial Statements”, Note 15 included herein, for the reconciliation of adjusted reportable segment EBITDA to loss before income taxes. Adjusted reportable segment EBITDA is the only measure of segment profit used by our chief operating decision maker.

Critical Accounting Estimates

There have been no material changes in our critical accounting policies and estimates during the three months ended March 29, 2025. Refer to the 2024 Form 10-K for a description of the Company’s critical accounting estimates.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There have been no significant changes in our exposure to market risk during the three months ended March 29, 2025. Refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, for a description of the Company’s market risks.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, under the supervision and participation of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of March 29, 2025. Based on the evaluation of our disclosure controls and procedures, our CEO and CFO concluded that, as of March 29, 2025, our disclosure controls and procedures were not effective due to the material weakness in our internal control over financial reporting as described below.

Notwithstanding the material weakness in our internal control over financial reporting, management has concluded that the unaudited consolidated financial statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity U.S. GAAP.

31

Material Weakness in Internal Control over Financial Reporting

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

Details on Previously Reported Material Weakness

In our Form 10-Q for the period ended September 28, 2024, management identified a material weakness in our internal control over financial reporting that arose from the ineffective application of the software development life cycle (“SDLC”) information technology general control. Specifically, the Company determined that the assigned team members lacked the requisite knowledge and experience to develop functional requirements, configure the system, and complete user acceptance tests sufficient to fully test the enterprise resource planning system prior to going live.

Remediation Efforts to Address the Material Weakness

Management has evaluated the deficiency described above and developed a remediation plan designed to strengthen our SDLC processes across the organization, to ensure we have appropriate methodology for additional implementations. The remediation plan requires that: (i) functional business experts are identified, trained, and meet established requirements, (ii) business users have sufficient understanding of the underlying functionality being tested, and (iii) additional levels of review are established throughout the SDLC. The remediation plan is subject to ongoing management review, as well as oversight by the Audit Committee of our Board of Directors.

Changes in Internal Control over Financial Reporting

Except for the material weakness identified by management and described above, there were no other changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the period ended March 29, 2025, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Description of Business

Cornerstone Building Brands, Inc. (“Cornerstone Building Brands” or, collectively with its subsidiaries, unless the context requires otherwise, the “Company”) is a holding company incorporated in the State of Delaware. The Company is a leading exterior building products manufacturer by sales in North America and serves residential and commercial customers across new construction and the repair and remodel end markets. The Company is organized in three reportable segments: Aperture Solutions, Surface Solutions and Shelter Solutions.

Basis of Presentation

The accompanying Condensed Consolidated Financial Statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These Condensed Consolidated Financial Statements have been prepared in accordance with the Company's accounting policies and on the same basis as those financial statements included in the Company’s latest Annual Report on Form 10-K for the year ended December 31, 2024, and should be read in conjunction with those Consolidated Financial Statements and the Notes thereto. Certain disclosures normally included in the Company’s Consolidated Financial Statements prepared in accordance with U.S. GAAP have been omitted on a basis consistent with the rules and regulations of the SEC. Certain items have been reclassified in the prior year disclosures to conform to the current year presentation.

The accompanying Condensed Consolidated Financial Statements include the accounts and operations of the Company and its majority-owned subsidiaries and all adjustments (consisting of normal recurring adjustments) that the Company considered necessary to present a fair statement of its results of operations, financial position and cash flows. All significant intercompany accounts and transactions have been eliminated in consolidation.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, net sales and expenses and related disclosures of contingent assets and liabilities in the Condensed Consolidated Financial Statements and accompanying notes. These estimates include, but are not limited to: establishing the allowance for expected credit losses; allowance for slow moving and obsolete inventory; the valuation of goodwill; establishing useful lives for and evaluating the recovery of our finite-life, long-lived assets; recognizing the fair value of assets acquired and liabilities assumed in business combinations; determining the fair value of contingent consideration; accounting for rebates and product warranties; the valuation and expensing for share-based compensation; certain assumptions made in accounting for pension benefits; accounting for contingencies and uncertainties; and accounting for income taxes. Actual results may differ from the estimates used in preparing the Condensed Consolidated Financial Statements.

Cash and Cash Equivalents

Cash and cash equivalents mainly consist of highly liquid, unrestricted savings, checking, money market funds with original maturities of less than three months and other bank accounts.

Accounts Receivable, Net

The Company reports accounts receivable net of an allowance for expected credit losses. The Company establishes provisions for expected credit losses based on the Company’s assessment of the collectability of amounts owed to the Company by its customers. Such allowances are included in selling, general and administrative expenses in the Company’s Condensed Consolidated Statements of Loss. In establishing the allowance, the Company considers changes in the financial position of a customer, age of the accounts receivable balances, availability of security, unusual macroeconomic conditions, lien rights and bond rights as well as disputes, if any, with its customers. Uncollectible accounts are written off when a settlement is reached for an amount that is less than the outstanding historical balance, all collection efforts have been exhausted or any legal action taken by the Company has concluded. The Company’s allowance for expected credit losses was $20.0 million and $26.3 million at March 29, 2025 and December 31, 2024, respectively.

Business Combinations

We account for business combinations under the acquisition method of accounting, which requires an allocation of the consideration we paid to the identifiable assets, intangible assets and liabilities based on the estimated fair values as of the closing date of the acquisition. The excess of the fair value of the purchase price over the fair values of these identifiable assets, intangible assets and liabilities is recorded as goodwill.

Purchased intangibles other than goodwill are initially recognized at fair value and amortized over their useful lives unless those lives are determined to be indefinite. The valuation of acquired assets will impact future operating results. The fair value of identifiable intangible assets is determined using an income approach on an individual asset basis. Specifically, we use the multi-period excess earnings method to determine the fair value of customer relationships and the relief-from-royalty approach to determine the fair value of trade names. Determining the fair value of acquired intangibles involves significant estimates and assumptions, including forecasted revenue growth rates, margins, percentage of revenue attributable to the trade name, contributory asset charges, customer attrition rate, market-participant discount rates, the assumed royalty rates and income tax rates.

The determination of the useful life of an intangible asset other than goodwill is based on factors including historical trade name performance with respect to consumer name recognition, geographic market presence, market share, plans for ongoing trade name support and promotion, customer attrition rate, and other relevant factors.

The initial purchase price allocation is based upon provisional information and is subject to revision during the measurement period (up to one year from the acquisition date) as additional information concerning valuations is obtained. As the Company obtains new information regarding facts and circumstances that existed as of the acquisition date that, if known, would have resulted in revised estimated values of those assets or liabilities, the Company will accordingly revise the provisional purchase price allocation. These adjustments may include, but are not limited to, adjustments pertaining to intangible assets acquired, property, plant and equipment acquired and tax liabilities assumed.

Recent Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. The new guidance requires consistent categorization and greater disaggregation of information in the rate reconciliation, as well as further disaggregation of income taxes paid. This change is effective for annual periods beginning after December 15, 2024. Prospective application is required, with retrospective application permitted. The Company is currently evaluating the effect the updated guidance will have on its financial statement disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement- Reporting Comprehensive Income- Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which improves disclosure requirements and provides more detailed information about an entity’s expenses, specifically amounts related to purchases of inventory, employee compensation, depreciation, intangible asset amortization and selling expenses, along with qualitative descriptions of certain other types of expenses. This change is effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the effect the updated guidance will have on its financial statement disclosures.

Acquisitions

Acquisitions

All purchase price allocations for acquired entities are based upon provisional information and are subject to revision during the measurement period (up to one year from the acquisition date) as additional information is obtained.

Acquisition of Mueller Supply Company, Inc.

In July 2024, the Company completed the acquisition of Mueller Supply Company, Inc. (“Mueller”) for a purchase price of $495.9 million, including a base purchase price of $475.0 million, in addition to closing date cash and working capital adjustments. Mueller is a leading manufacturer of residential metal roofing and components and steel buildings in Texas and the Southwest United States (“U.S.”). Mueller has approximately 900 employees and a comprehensive regional footprint including 38 retail branches and five manufacturing sites in Amarillo, Ballinger and Huntsville, Texas; Oak Grove, Louisiana; and Phoenix, Arizona. This acquisition was funded through issuing long-term debt further discussed in Note 7. Mueller is included in the Company’s Shelter Solutions reportable segment.

The following table summarizes the provisional fair value of net assets acquired:

	Fair Value
Cash and cash equivalent	$	18,074
Accounts receivable	10,346
Inventories	126,516
Property, plant and equipment	207,912
Goodwill	107,543
Trade name and customer relationship intangibles	108,000
Equity investment	11,000
Other assets	5,803
Total assets acquired	595,194
Accounts payable and other liabilities assumed	8,805
Employee related liabilities	5,876
Rebates and customer related liabilities	16,698
Deferred income tax liabilities	67,924
Total liabilities assumed	99,303
Net assets acquired	$	495,891

During the three months ended March 29, 2025, the Company recognized a $3.1 million increase in accounts payable and other liabilities assumed and a corresponding decrease of $3.1 million in employee related liabilities. The Company recorded these measurement period adjustments to update the allocation of the purchase price based upon further analysis of information subsequent to the acquisition date. These adjustments did not have a material impact on the Company’s Condensed Consolidated Statements of Loss for the three months ended March 29, 2025.

As part of the Mueller transaction, the Company acquired a 33.33% interest in BDM Metal Coaters, LLC (“BDM”). The general purpose of BDM is the establishment and operation of a processing facility for the slitting and coating of hot roll steel coils. The Company possesses the ability to exercise significant influence, but not control, over the operating and financial policies of BDM; therefore, the Company accounts for the investment under the equity method of accounting. The carrying value of the investment was $10.7 million as of March 29, 2025 and $11.1 million as of December 31, 2024. The investment in BDM is recognized in other assets, net on our Condensed Consolidated Balance Sheets for both comparable periods.

The fair value and expected useful life of identifiable intangible assets consists of the following:

	Fair Value		Useful Life in Years
Customer relationships	$	30,000	11
Trade names and other	78,000		12
Total	$	108,000

The acquisition of Mueller resulted in the recognition of $107.5 million of goodwill. The goodwill recorded is a result of expected synergies and other benefits that we believe will result from the integration of the acquisition within our operations. Goodwill created as a result of the acquisition of Mueller is not expected to be deductible for tax purposes. A net deferred tax liability of $67.9 million was established as a result of the acquisition.

Acquisition of Harvey Building Products Corp.

In April 2024, the Company completed the acquisition of Harvey Building Products Corp. (“Harvey”) for a purchase price of $460.7 million, subject to certain customary adjustments. Harvey is a manufacturer of high performing windows and doors, and its portfolio of industry leading brands include Harvey, Softlite and Thermo-Tech. Headquartered in Waltham, Massachusetts, Harvey has approximately 1,200 employees at four manufacturing facilities located throughout the Northeast and Midwest. Harvey specializes in premium, custom windows and doors primarily serving the Eastern U.S. This acquisition was funded through issuing long-term debt further discussed in Note 7. Harvey is included in the Company’s Aperture Solutions reportable segment.

The following table summarizes the provisional fair value of net assets acquired:

	Fair Value
Cash and cash equivalent	$	10,423
Accounts receivable	27,325
Inventories	21,535
Property, plant and equipment	47,478
Lease right-of-use assets	123,801
Goodwill	173,204
Trade name and customer relationship intangibles	246,000
Other assets	7,375
Total assets acquired	657,141
Accounts payable and other liabilities assumed	36,080
Employee related liabilities	6,208
Lease liabilities	104,807
Deferred income tax liabilities	49,384
Total liabilities assumed	196,479
Net assets acquired	$	460,662

During the three months ended March 29, 2025, the Company recognized a $0.6 million decrease in lease right-of-use assets, a $9.2 million decrease in other assets, $9.2 million decrease in deferred income tax liabilities and a $0.6 million increase in goodwill as a result of these measurement period adjustments. The Company recorded these measurement period adjustments to update the allocation of the purchase price based upon further analysis of information subsequent to the acquisition date. These adjustments did not have a material impact on the Company’s Condensed Consolidated Statements of Loss for the three months ended March 29, 2025.

The fair value and expected useful life of identifiable intangible assets consists of the following:

	Fair Value		Useful Life in Years
Customer relationships	$	200,000	12
Trade names and other	46,000		12
Total	$	246,000

The acquisition of Harvey resulted in the recognition of $173.2 million of goodwill. The goodwill recorded is a result of expected synergies and other benefits that we believe will result from the integration of the acquisition with our operations. Goodwill created as a result of the acquisition of Harvey is not expected to be deductible for tax purposes. A net deferred tax liability of $49.4 million was established as a result of the acquisition.

Contingent Consideration for Acquisition Completed during 2023

In August 2023, the Company completed the acquisition of M.A.C. Métal Architectural Inc. (“MAC Metal”), which became an indirect wholly-owned subsidiary of the Company. Headquartered in Saint-Hubert, Quebec, MAC Metal serves the North American residential and commercial markets with high-end steel siding and roofing products. MAC Metal is included in the Company’s Surface Solutions reportable segment. The total purchase price included earn-out contingent consideration of $16.8 million payable over two consecutive twelve-month periods, with the first period starting in the month following the close of the acquisition and payments are based upon achieving certain adjusted EBITDA-based metrics, as defined in the purchase agreement. There was an increase of $1.0 million in contingent consideration in the three months ended March 29, 2025, including the impact of exchange rates. Total contingent consideration of $22.1 million as of March 29, 2025 and $21.1 million as of December 31, 2024 is recognized in other current liabilities on our Condensed Consolidated Balance Sheets

In April 2018, Ply Gem Midco entered into a Cash Flow Agreement (as amended from time to time, the “Cash Flow Credit Agreement”); facilities provided thereunder, including the Term Loan Facility, due April 2028, the Term Loan Facility, due May 2031 and the Cash Flow Revolver (each as defined below), the “Cash Flow Facilities”), which provides for (i) a term loan facility (the “Term Loan Facility, due April 2028”) in the aggregate principal amount of $2,600.0 million, issued with a discount of 0.5% and (ii) a cash flow-based revolving credit facility (the “Cash Flow Revolver”) of up to $115.0 million. In connection with the consummation of the Ply Gem merger, the Company and Ply Gem Midco entered into a joinder agreement in which the Company became the Borrower (as defined in the Cash Flow Credit Agreement). On April 11, 2023, the Company amended the Cash Flow Credit Agreement to replace the adjusted LIBOR rate with the Secured Overnight Financing Rate (“SOFR”) rate. On May 15, 2024, the Company entered into a Fifth Amendment to the Cash Flow Credit Agreement (the “Cash Flow Fifth Amendment”) to, among other things, terminate the $92.0 million of commitments under the Cash Flow Revolver and replace such commitments with $92.0 million of extended cash flow-based revolving commitments, maturing on May 15, 2029 (subject to a springing maturity under certain circumstances) and (b) incur a new incremental term loan facility (the “Term Loan Facility, due May 2031”) in the aggregate principal amount of $500.0 million, maturing on May 15, 2031 (subject to a springing maturity under certain circumstances).

The Term Loan Facility, due April 2028 amortizes in nominal quarterly installments equal to one percent of the aggregate initial principal amount thereof per annum, with the remaining balance payable upon final maturity. The Term Loan Facility, due April 2028 bears annual interest at a floating rate measured by reference to, at the Company’s option, either (i) a Term SOFR rate with a credit spread adjustment of 0.10% (subject to a floor of 0.50%) plus an applicable margin of 3.25% per annum or (ii) an alternate base rate plus an applicable margin of 2.25% per annum.

Loans outstanding under the Cash Flow Revolver bear annual interest at a floating rate measured by reference to, at the Company’s option, either (i) a Daily Simple SOFR rate or a Term SOFR rate with (only in the case of Term SOFR rate borrowings with an interest period greater than one month) a credit spread adjustment of 0.10% (subject to a floor of 0.00%) plus an applicable margin ranging from 2.50% to 3.00% per annum depending on the Company’s secured leverage ratio or (ii) an alternate base rate plus an applicable margin ranging from 1.50% to 2.00% per annum depending on the Company’s secured leverage ratio. There are no amortization payments under the Cash Flow Revolver. Additionally, unused commitments under the Cash Flow Revolver are subject to a fee ranging from 0.25% to 0.50% per annum depending on the Company’s secured leverage ratio.

The Term Loan Facility, due May 2031, amortizes in nominal quarterly installments equal to one percent of the aggregate initial principal amount thereof per annum, with the remaining balance payable upon maturity. The Term Loan Facility, due May 2031 bears annual interest at a floating rate measured by reference to, at the Company’s option, either (i) a Term SOFR rate (subject to a floor of 0.50%) plus an applicable margin of 4.50% per annum or (ii) an alternate base rate plus an applicable margin of 3.50% per annum.

Subject to certain exceptions, the Term Loan Facility, due April 2028 and the Term Loan Facility due May 2031 are subject to mandatory prepayments in an amount equal to:

•the net cash proceeds of (i) certain asset sales, (ii) certain debt offerings and (iii) certain insurance recovery and condemnation events; and

•50% of annual excess cash flow (as defined in the Cash Flow Credit Agreement), subject to reduction to 25% and 0% if specified secured leverage ratio targets are met to the extent that the amount of such excess cash flow exceeds $10.0 million. No payments were required in 2022 under the year 2021 excess cash flow calculation.

The Term Loan Facility, due April 2028, the Term Loan Facility, due May 2031 and the Cash Flow Revolver may be prepaid at the Company’s option at any time without premium or penalty (other than customary breakage costs), subject to minimum principal amount requirements.

ABL Facility, due May 2029

On April 12, 2018, Ply Gem Midco entered into an ABL Credit Agreement (as amended from time to time, the “ABL Credit Agreement”), which provides for (a) an asset-based revolving credit facility of up to $850.0 million (amended from time to time the “ABL Facility”), a portion of which is (i) available to U.S. borrowers and (ii) available to U.S. and Canadian borrowers. In connection with the consummation of the Ply Gem merger, the Company and Ply Gem Midco entered into a joinder agreement in which the Company became the Parent Borrower (as defined in the ABL Credit Agreement) under the ABL Facility, and (b) a first-in-last-out tranche asset-based revolving credit facility of up to $95.0 million (the “ABL FILO Facility”) available to U.S. borrowers.

On May 15, 2024, the Company entered into Amendment No. 8 to the ABL Credit Agreement (“Amendment No. 8”), which amended the ABL Credit Agreement in order to terminate the existing revolving commitments under the ABL Facility and the ABL FILO Facility originally maturing on July 25, 2027 (the “Existing ABL Commitments”), and replace such Existing ABL Commitments with an extended revolving commitment of $945.0 million maturing on May 15, 2029 (subject to a springing maturity under certain circumstances), subject to the outstanding aggregate principal amount.

Borrowing availability under the ABL Facility and the ABL FILO Facility (collectively, the “ABL Facilities”) is determined by a monthly borrowing base collateral calculation that is based on specified percentages of the value of eligible inventory, accounts receivable, less certain allowances and subject to certain other adjustments as set forth in the ABL Credit Agreement. Availability is reduced by issuance of letters of credit as well as any borrowings.

Loans outstanding under the ABL Facility bear interest at a floating rate measured by reference to, at the Company’s option, either (i) a Term SOFR rate (subject to a SOFR floor of 0.00%) plus an applicable margin ranging from 1.25% to 1.75% per annum depending on the average daily excess availability under the ABL Facility or (ii) an alternate base rate plus an applicable margin ranging from 0.25% to 0.75% per annum depending on the average daily excess availability under the ABL Facility. Additionally, unused commitments under the ABL Facility are subject to a 0.25% per annum fee.

Loans outstanding under the ABL FILO Facility bear interest at a floating rate measured by reference to, at the Company’s option, either (i) a term SOFR rate (subject to a SOFR floor of 0.00%) plus an applicable margin ranging from 2.25% to 2.75% per annum depending on the average daily excess availability under the ABL FILO Facility or (ii) an alternate base rate plus an applicable margin ranging from 1.25% to 1.75% per annum depending on the average daily excess availability under the ABL FILO Facility. Additionally, unused commitments under the ABL FILO Facility are subject to a 0.25% per annum fee.

Covenant Compliance

The ABL Credit Agreement includes a minimum fixed charge coverage ratio of 1.00:1.00, which is tested only when specified availability is less than 10.0% of the lesser of (x) the then applicable borrowing base and (y) the then aggregate effective commitments under the ABL Facility and continuing until such time as specified availability has been in excess of such threshold for a period of 20 consecutive calendar days. The Cash Flow Credit Agreement includes a financial covenant set at a maximum secured leverage ratio of 7.75:1.00, which will apply if the outstanding amount of loans and drawings under letters of credit which have not then been reimbursed exceeds a specified threshold at the end of any fiscal quarter.

The Company’s debt agreements contain a number of covenants that, among other things, limit or restrict the ability of the Company and its subsidiaries to incur additional indebtedness; make dividends and other restricted payments; incur additional liens; consolidate, merge, sell or otherwise dispose of all or substantially all assets; make investments; transfer or sell assets; enter into restrictive agreements; change the nature of the business; and enter into certain transactions with affiliates. The Company is in compliance with all of its covenants as of March 29, 2025.

Interest Rate Swaps

The Company uses certain interest rate swaps to manage a portion of the interest rate risk on its term loans. The following table sets forth the terms of the Company’s interest rate swap agreements:

Notional amount	$	1,500,000
Forecasted term loan interest payments being hedged	1-month SOFR
Fixed rate paid	2.0038%
Origination date	April 17, 2023
Maturity date	April 15, 2026
Fair value at March 29, 2025 - Other assets, net	$	29,427
Fair value at December 31, 2024 - Other assets, net	$	39,159
Level in fair value hierarchy(1)	Level 2

(1)Interest rate swaps are based on cash flow hedge contracts that have fixed rate structures and are measured against market based SOFR yield curves. These interest rate swaps are classified within Level 2 of the fair value hierarchy because they are valued using alternative pricing sources or models that utilized market observable inputs, including current and forward interest rates.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments and Fair Value Measurements

Fair Value of Financial Instruments and Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis. 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. The Company uses a three-level hierarchy for fair value measurements based on the observability of inputs to the valuation of an asset or liability as of the measurement date. The three levels of the fair value hierarchy are as follows:

•Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities.

•Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

•Level 3 – Unobservable inputs for the asset or liability, reflecting the Company’s own assumptions about the assumptions that market participants would use in pricing the asset or liability.

Fair Value Measurements on a Recurring Basis

The following table presents the Company’s financial assets and liabilities measured at fair value on a recurring basis as of March 29, 2025:

	Level 1		Level 2		Level 3		Total
Assets – Derivative instruments	$	—	$	29,427	$	—	$	29,427
Liabilities – Contingent consideration	$	—	$	—	$	22,100	$	22,100

The following table presents the Company’s financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2024:

	Level 1		Level 2		Level 3		Total
Assets – Derivative instruments	$	—	$	39,159	$	—	$	39,159
Liabilities – Contingent consideration	$	—	$	—	$	21,122	$	21,122

The fair value for derivative instruments is determined using valuation models that incorporate observable market inputs, such as interest rates and currency exchange rates, and is classified within Level 2 of the fair value hierarchy.

The fair value of contingent consideration is estimated as of the date of the acquisition and is recorded as part of the purchase price, and is subsequently re-measured to fair value at each reporting date, based on a probability-weighted analysis using a rate that reflects the uncertainty surrounding the expected outcomes, which the Company believes is appropriate and representative of market participant assumptions.

Fair Value Measurement Disclosure

The fair value of the Company’s short-term debt is estimated using observable market inputs, including current interest rates for similar types of borrowings. The fair value of long-term debt is determined based on quoted prices for identical or similar

instruments in active markets. The fair value of the senior notes is based on quoted prices in active markets for the identical liabilities. The fair value of the term loans is based on recent trading activities of comparable market instruments.

Non-Recurring Fair Value Measurements

Certain assets and liabilities are measured at fair value on a non-recurring basis. These include assets and liabilities that are measured at fair value in the event of impairment or for disclosure purposes. The discounted cash flow method under the income approach is generally employed to estimate the fair value of the reporting units or identified asset groups. For reporting units, the guideline public company method and the guideline transaction method are also utilized under the market approach. Significant assumptions inherent in estimating fair values include the projected future annual net cash flows for each reporting unit, encompassing net sales, cost of sales, selling, general and administrative expenses, depreciation and amortization, working capital, and capital expenditures. Other critical assumptions involve income tax rates, long-term growth rates, and a discount rate that appropriately reflects the risks inherent in each future cash flow stream.

Fair Value of Financial Instruments Not Measured at Fair Value

The carrying amounts of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, and accrued liabilities approximate their fair values due to the short-term nature of these instruments

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

As a manufacturer of products primarily for use in building construction, the Company is inherently exposed to various types of contingent claims, both asserted and unasserted, in the ordinary course of business. As a result, from time to time, the Company may become involved in various legal proceedings or other contingent matters arising from claims or potential claims arising out of its operations and businesses that cover a wide range of matters, including, among others, environmental, contract, employment, including applicable benefit and pension plans, intellectual property, securities, personal injury, property damage, product liability, warranty and modification, adjustment or replacement of component parts or units sold, which may include product recalls. The Company insures (or self-insures) against these risks to the extent deemed prudent by its management and to the extent insurance is available. Management believes that the ultimate disposition of these matters will not have a material adverse effect on the Company’s results of operations, financial position or cash flows. However, such matters are subject to many uncertainties and outcomes and are not predictable with assurance. The Company believes it is adequately reserved for all matters.

Environmental

The Company’s operations are subject to various federal, state, local and foreign environmental, health and safety laws. Among other things, these laws regulate the emissions or discharge of contaminants into the environment; govern the use, storage, treatment, disposal and management of hazardous substances and wastes; protect employee health and safety, public health and welfare and the end-users of its products; regulate the chemicals used in its products; and impose liability for the costs of investigating and remediating (as well as other damages resulting from) present and past releases of hazardous substances. Violations of these laws or of any conditions contained in environmental permits could impact the Company's current and future operations.

The Company believes it is in material compliance with all applicable laws and regulations and has recorded a liability of $4.1 million as of March 29, 2025 and December 31, 2024 for certain subsurface investigation and remedial matters.

Litigation

The Company is a party to a variety of legal actions arising out of the normal course of business. Plaintiffs occasionally seek punitive or exemplary damages. The Company is also included in other kinds of legal actions, some of which assert or may assert claims or seek to impose fines or penalties and other costs in substantial amounts and are described below.

Stockholder Litigation

In July 2022, and pursuant to an Agreement and Plan of Merger dated March 5, 2022 Clayton, Dubilier and Rice, LLC (“CD&R”) became the indirect owner of Cornerstone Building Brands (the “Merger”). In January 2023, purported former stockholders filed 2 separate complaints challenging the fairness of the Merger. The complaints are captioned Firefighters’ Pension System of the City of Kansas City, Missouri Trust and Gary D. Voigt v. Affeldt et al., C.A. No. 2023-0091-JTL (Del. Ch.) and Whitebark Value Partners LP and Robert Garfield v. Clayton Dubilier & Rice, LLC et al., C.A. No. 2023-0092-JTL (Del. Ch.). In both complaints, the plaintiffs allege that CD&R and its affiliates controlled the Company prior to the transaction and that certain directors and officers of the Company, as well as CD&R and its affiliates, breached their fiduciary duties and engaged in conduct resulting in a sale of the Cornerstone Building Brands public stockholders’ shares to CD&R at an unfair price. The plaintiffs seek unspecified monetary damages, attorneys’ fees, expenses and costs. The court consolidated the two cases, and on May 3, 2023, selected Whitebark Value Partners LP as lead plaintiff. On July 14, 2023, the defendants moved to dismiss the operative complaint. The motion to dismiss was denied on January 10, 2024, and the case is ongoing. On June 26, 2024, the plaintiffs filed an amended complaint. On February 24, 2025, the parties to the case filed a Stipulation of Compromise and Settlement (“Stipulation”) setting forth their agreement to settle the litigation. The Stipulation remains subject to court approval. The Stipulation provides for CD&R and the Company, on behalf of the defendants, to pay or cause their respective insurers to pay a total of $45.0 million into an escrow account that will be used to pay escrow expenses, satisfy any fee and incentive amounts awarded by the court in favor of plaintiff and plaintiff’s counsel, and distribute the remaining funds to the non-affiliated shareholders of the Company. The Company's portion of the proposed settlement relating to its indemnification of its former directors and officers is recoverable from insurance. The agreement is contingent upon final court approval, for which a hearing is scheduled on May 29, 2025.

In June 2023, a purported former stockholder filed a class action complaint in the United States District Court for the District of Delaware alleging that the Company’s disclosures issued in connection with the Merger were materially misleading in violation of Section 14(a) and Section 20(a) of the Securities Exchange Act of 1934. The complaint is captioned Water Island Merger Arbitrage Institutional Commingled Master Fund, L.P. v. Cornerstone Building Brands et al., Case No. 1:23-cv-00701 (D. Del.). The complaint alleges that the Company’s directors and officers issued misleading disclosures, which caused stockholders to approve the Merger at an unfair price. The plaintiff seeks unspecified monetary damages, interest, attorney’s fees, expenses and costs. On December 8, 2023, the defendants moved to dismiss the operative complaint, and, in the alternative, to stay in litigation. On September 30, 2024, the court granted the defendants’ motion to dismiss without prejudice. On October 15, 2024, the plaintiffs filed an amended complaint, which the defendants again moved to dismiss or stay on November 26, 2024. The Company intends to vigorously defend against these claims. The Company cannot predict with any degree of certainty the outcome of this matter or determine the extent of any potential liabilities. The Company also cannot provide an estimate of the possible loss or range of loss.

Segment Reporting [Abstract]

Reportable Segment and Geographical Information

Reportable Segment and Geographical Information

Operating segments are defined as components of an enterprise for which discrete financial information is available that is evaluated regularly by the chief operating decision maker (“CODM”) for purposes of allocating resources and evaluating financial performance. Our CODM, who is our Chief Executive Officer, reviews financial information presented on a consolidated basis for the purposes of allocating resources and evaluating financial performance. The Company is organized in five operating segments aggregated into three reportable segments: Aperture Solutions (consisting of the Aperture Solutions–U.S. and Aperture Solutions–Canada operating segments), Surface Solutions (consisting of the Surface Solutions–U.S. and Surface Solutions–Canada operating segments) and Shelter Solutions, itself an operating segment. The aggregated reportable segments share similar economic characteristics with respect to product offerings, manufacturing processes, and customer demographics. We operate principally in the U.S. with limited operations in Canada.

•The Aperture Solutions reportable segment offers a broad line of windows and doors at multiple price-points for residential new construction and repair and remodel end markets in the U.S. and Canada. Its main products include vinyl, aluminum, wood-composite and aluminum clad-wood windows and patio doors, as well as steel, wood-composite, and fiberglass entry doors.

•The Surface Solutions reportable segment offers a broad suite of surface solutions products and accessories at multiple price-points for the residential new construction and repair and remodel end markets as well as stone installation services. Its main products include vinyl siding and accessories, cellular polyvinyl chloride trim, vinyl fencing and railing, stone veneer and gutter protection products.

•The Shelter Solutions reportable segment designs, engineers, manufactures and distributes extensive lines of metal products for the low-rise commercial construction market under multiple brand names and through a nationwide network of manufacturing plants, distribution centers and retail branches. The Company defines low-rise commercial construction as building applications of up to five stories.

Management monitors the operations results of its operating segments separately for purposes of making decisions about resources and evaluating performance. Management, including the Company’s chief operating decision maker, evaluates performance on the basis of segment earnings before interest, income taxes, depreciation and amortization (“Adjusted reportable segment EBITDA”).

Corporate operating expenses are not allocated to reportable segments. Corporate and Other consists specifically of corporate operating expenses that are generally not allocated to reportable segments, related-party management fees, and other items that are not assigned or allocated to reportable segments. Any intercompany net sales or expenses are eliminated in consolidation.

Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying Condensed Consolidated Financial Statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These Condensed Consolidated Financial Statements have been prepared in accordance with the Company's accounting policies and on the same basis as those financial statements included in the Company’s latest Annual Report on Form 10-K for the year ended December 31, 2024, and should be read in conjunction with those Consolidated Financial Statements and the Notes thereto. Certain disclosures normally included in the Company’s Consolidated Financial Statements prepared in accordance with U.S. GAAP have been omitted on a basis consistent with the rules and regulations of the SEC. Certain items have been reclassified in the prior year disclosures to conform to the current year presentation.

The accompanying Condensed Consolidated Financial Statements include the accounts and operations of the Company and its majority-owned subsidiaries and all adjustments (consisting of normal recurring adjustments) that the Company considered necessary to present a fair statement of its results of operations, financial position and cash flows. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, net sales and expenses and related disclosures of contingent assets and liabilities in the Condensed Consolidated Financial Statements and accompanying notes. These estimates include, but are not limited to: establishing the allowance for expected credit losses; allowance for slow moving and obsolete inventory; the valuation of goodwill; establishing useful lives for and evaluating the recovery of our finite-life, long-lived assets; recognizing the fair value of assets acquired and liabilities assumed in business combinations; determining the fair value of contingent consideration; accounting for rebates and product warranties; the valuation and expensing for share-based compensation; certain assumptions made in accounting for pension benefits; accounting for contingencies and uncertainties; and accounting for income taxes. Actual results may differ from the estimates used in preparing the Condensed Consolidated Financial Statements.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents mainly consist of highly liquid, unrestricted savings, checking, money market funds with original maturities of less than three months and other bank accounts.

Accounts Receivable, Net

Accounts Receivable, Net

The Company reports accounts receivable net of an allowance for expected credit losses. The Company establishes provisions for expected credit losses based on the Company’s assessment of the collectability of amounts owed to the Company by its customers. Such allowances are included in selling, general and administrative expenses in the Company’s Condensed Consolidated Statements of Loss. In establishing the allowance, the Company considers changes in the financial position of a customer, age of the accounts receivable balances, availability of security, unusual macroeconomic conditions, lien rights and bond rights as well as disputes, if any, with its customers. Uncollectible accounts are written off when a settlement is reached for an amount that is less than the outstanding historical balance, all collection efforts have been exhausted or any legal action taken by the Company has concluded.

Business Combinations

Business Combinations

We account for business combinations under the acquisition method of accounting, which requires an allocation of the consideration we paid to the identifiable assets, intangible assets and liabilities based on the estimated fair values as of the closing date of the acquisition. The excess of the fair value of the purchase price over the fair values of these identifiable assets, intangible assets and liabilities is recorded as goodwill.

Purchased intangibles other than goodwill are initially recognized at fair value and amortized over their useful lives unless those lives are determined to be indefinite. The valuation of acquired assets will impact future operating results. The fair value of identifiable intangible assets is determined using an income approach on an individual asset basis. Specifically, we use the multi-period excess earnings method to determine the fair value of customer relationships and the relief-from-royalty approach to determine the fair value of trade names. Determining the fair value of acquired intangibles involves significant estimates and assumptions, including forecasted revenue growth rates, margins, percentage of revenue attributable to the trade name, contributory asset charges, customer attrition rate, market-participant discount rates, the assumed royalty rates and income tax rates.

The determination of the useful life of an intangible asset other than goodwill is based on factors including historical trade name performance with respect to consumer name recognition, geographic market presence, market share, plans for ongoing trade name support and promotion, customer attrition rate, and other relevant factors.

The initial purchase price allocation is based upon provisional information and is subject to revision during the measurement period (up to one year from the acquisition date) as additional information concerning valuations is obtained. As the Company obtains new information regarding facts and circumstances that existed as of the acquisition date that, if known, would have resulted in revised estimated values of those assets or liabilities, the Company will accordingly revise the provisional purchase price allocation. These adjustments may include, but are not limited to, adjustments pertaining to intangible assets acquired, property, plant and equipment acquired and tax liabilities assumed.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. The new guidance requires consistent categorization and greater disaggregation of information in the rate reconciliation, as well as further disaggregation of income taxes paid. This change is effective for annual periods beginning after December 15, 2024. Prospective application is required, with retrospective application permitted. The Company is currently evaluating the effect the updated guidance will have on its financial statement disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement- Reporting Comprehensive Income- Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which improves disclosure requirements and provides more detailed information about an entity’s expenses, specifically amounts related to purchases of inventory, employee compensation, depreciation, intangible asset amortization and selling expenses, along with qualitative descriptions of certain other types of expenses. This change is effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the effect the updated guidance will have on its financial statement disclosures.

Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis. 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. The Company uses a three-level hierarchy for fair value measurements based on the observability of inputs to the valuation of an asset or liability as of the measurement date. The three levels of the fair value hierarchy are as follows:

•Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities.

•Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

•Level 3 – Unobservable inputs for the asset or liability, reflecting the Company’s own assumptions about the assumptions that market participants would use in pricing the asset or liability.
