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 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 into 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, 2023 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.

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

Summary of 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 obsolete inventory; the impairment of goodwill and intangible assets; establishing useful lives for and evaluating the recovery of long-lived assets; recognizing the fair value of assets acquired and liabilities assumed in business combinations; determining the fair value of contingent considerations; 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.

The following table sets forth the components of cash and cash equivalents:

	March 30, 2024		December 31, 2023
Cash	$	117,299	$	228,975
Money market funds (Level 1 securities)	—		239,902
Total cash and cash equivalents	$	117,299	$	468,877

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 $6.4 million and $9.6 million at March 30, 2024 and December 31, 2023.

Fair Value Measurements

The carrying amounts of cash and cash equivalents, trade accounts receivable and accounts payable approximate fair value as of March 30, 2024 and December 31, 2023 given the instruments’ relatively short maturities. The carrying amounts of the indebtedness under revolving credit facilities approximate fair value as the interest rates are variable and reflective of market rates. Fair values for our other debt instruments are measured using Level 1 and Level 2 inputs. U.S. GAAP requires us to use valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized as follows:

Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets.

Level 2: Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities or market-corroborated inputs.

Level 3: Unobservable inputs for which there is little or no market data and which require us to develop our own assumptions about how market participants would price the assets or liabilities.

In connection with certain business acquisitions, the Company periodically enters into agreements that require us to pay additional consideration to the relevant seller. These payments are contingent on the achievement of specified EBITDA targets in periods subsequent to the acquisition. The fair value of contingent consideration is based on unobservable, or Level 3, inputs including a probability-weighted average payout approach. Contingent consideration obligations are measured at fair value each reporting period and any adjustments to fair value are recognized in earnings in the period they are identified. The Company has not made any changes to the methods used to determine the fair value of its contingent consideration obligations.

Recent Accounting Pronouncements

In November 2023, the FASB issued Accounting Standards Update (“ASU”) No. 2023-07, Improvements to Reportable Segment Disclosures (Topic 280). This ASU updates reportable segment disclosure requirements by requiring disclosures of significant reportable segment expenses that are regularly provided to the Chief Decision Maker (“CODM”) and included within each reported measure of a segment’s profit or loss. This ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources. The ASU is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Adoption of the ASU should be applied retrospectively to all prior periods presented in the financial statements. Early adoption is also permitted. The ASU will likely result in us including the additional required disclosures when adopted. We are currently evaluating the provisions of this ASU and expect to adopt them for the year ending December 31, 2024.

In December 2023, the FASB issued ASU 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.

Note 3 — Acquisitions

Acquisitions 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. In December 2023, the Company completed the acquisition of the Eastern Architectural Systems (“EAS”) business, whose operations are included in the Company’s Aperture Solutions reportable segment. EAS is based in Ft. Myers, Florida and manufactures custom-made aluminum and vinyl impact windows and doors.

The total purchase price for these acquisitions was $234.9 million comprised of upfront cash payments of $217.7 million and earn-out contingent consideration of $16.8 million related to the MAC Metal transaction. The EAS transaction is subject to a final working capital adjustment. The purchase price of these acquisitions was provisionally allocated to the assets acquired and liabilities assumed, which related primarily to inventory of $15.9 million, property, plant and equipment of $21.3 million, goodwill of $87.5 million, intangible assets such as, customer lists and trademarks, of $73.4 million and $34.3 million, contingent consideration of $16.8 million and noncurrent deferred income tax liabilities of $12.3 million. The goodwill recorded is a result of expected synergies and other benefits that we believe will result from the integration of the acquisitions with our operations.

The MAC Metal acquisition earn-out is payable over two consecutive twelve-month periods, with the first period starting in the month following the close of the applicable acquisition and payments are based upon achieving certain adjusted EBITDA-based metrics, as defined in the purchase agreement. There was no change to the fair-value of the contingent consideration of $16.8 million, of which $7.8 million is recognized in other current liabilities and $9.0 million is recognized in other long-term liabilities on our Condensed Consolidated Balance Sheets at March 30, 2024.

2024 Pending Acquisition

In March 2024, the Company reached an agreement to acquire Harvey Building Products Corp. (“Harvey”), a manufacturer of high performing windows and doors, and its portfolio of industry leading brands: 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 United States (“U.S.”). The transaction is subject to regulatory approval and customary closing conditions and is expected to close in the second quarter of 2024. Upon closing, the business will be integrated into our Aperture Solutions reportable segment.

Repurchase of 6.125% Senior Notes due January 2029

The Company repurchased an aggregate principal amount of $21.7 million of 6.125% Senior Notes for $15.5 million in cash during the three months ended April 1, 2023. The repurchases, which resulted in a write-off of associated unamortized debt discount and deferred financing costs, resulted in a loss of $0.6 million, recognized as a loss on extinguishment in the debt in the Condensed Consolidated Statements of Loss for the three months ended April 1, 2023. There were no repurchases of the Company’s 6.125% Senior Notes during the three months ended March 30, 2024.

(2)     Cash flow revolver commitment of $92.0 million will mature in April 2026.

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 30, 2024.

11

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:

	April 2021 Swaps
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 30, 2024 - Other assets, net	$	72,540
Fair value at December 31, 2023 - Other assets, net	$	64,704
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

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

Note 9 — Share-Based Compensation

Pre-Merger Awards

In connection with the Merger in July 2022, under which Cornerstone Building Brands became a privately held company, unvested share-based compensation awards that were previously granted to key employees and executives were cancelled and converted into a contingent contractual right to receive a cash payment from the Company upon vesting. The Company had $27.6 million at December 31, 2023 and $3.0 million at March 30, 2024 classified as a current liability within employee-related liabilities on its Condensed Consolidated Balance Sheets. The Company paid out $24.7 million of cash to settle Pre-Merger Awards in March 2024.

The Company recognized $1.5 million as expense in the three months ended March 30, 2024 and a gain of $4.8 million for the three months ended April 1, 2023. These amounts are included in selling, general and administrative expense on the Condensed Consolidated Statements of Loss. The gain during the three months ended April 1, 2023 resulted from the Company updating its vesting expectations for certain performance share units.

12

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”). 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 30, 2024, 24,010 incentive units were granted at an average grant date fair value of $46.71 per incentive unit. For the three months ended March 30, 2024, the Company recognized $1.6 million of expense from incentive units and the Company estimates that the unrecognized expense is expected to be recognized over a weighted-average period of 3.6 years totaling $29.5 million. During the three months ended April 1, 2023, the Company recognized $2.5 million of expense related to incentive units.

Note 10 — Equity Transactions

Dividend

In January 2024, the Board of Directors approved the payment of 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.

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 30, 2024 and three months ended April 1, 2023:

	Three Months Ended
	March 30, 2024		April 1, 2023
Effective tax rate	(14.9)	%	23.0	%

The change in the effective tax rate for the three months ended March 30, 2024 compared to the three months ended April 1, 2023 is due to the change in state tax expense period over period.

Note 12 — 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, the Chief Executive Officer, reviews financial information presented on a consolidated basis, accompanied by information about our five operating segments, for the purposes of allocating resources and evaluating financial performance. The Company is organized into three reportable segments: Aperture Solutions, Surface Solutions and Shelter Solutions, which 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 and distribution centers. The Company defines low-rise commercial construction as building applications of up to five stories.

Management monitors the operational results of its reportable segments separately for purposes of making decisions about resources and evaluating performance. Management evaluates performance on the basis of segment earnings before interest, income taxes, depreciation and amortization (“Adjusted reportable segment EBITDA”).

13

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 revenues or expenses are eliminated in consolidation.

Note 13 — 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.

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 $8.5 million as of March 30, 2024 and $8.8 million as of December 31, 2023 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. In January 2023, purported former stockholders filed two 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. The Company intends to vigorously defend against these claims. The Company cannot predict with any degree of certainty the outcome of these matters or determine the extent of any potential liabilities. The Company also cannot provide an estimate of the possible loss or range of loss.

15

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, attorneys’ fees, expenses, and costs. On December 8, 2023, the defendants moved to dismiss the operative complaint, and, in the alternative, to stay the litigation. 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. The Company does not believe, based on currently available information, that the outcome of these proceedings will have a material adverse effect on its financial condition.

% of net sales	9.3		%	11.0		%
* Refer to Non-GAAP Financial Measures for further discussion.

Net sales decreased $133.4 million, or 10.4%, for the three months ended March 30, 2024 compared to the three months ended April 1, 2023, mainly due to lower volume across all reportable segments, partially offset by the strategic acquisitions of M.A.C. Métal Architectural Inc. (“MAC Metal”) in August 2023 and Eastern Architectural Systems (“EAS”) in December 2023.

Gross profit as a percentage of net sales was 20.4% for the three months ended March 30, 2024, compared to 22.0% for the three months ended April 1, 2023. The decrease was driven by lower volumes, partially offset by manufacturing net efficiencies.

Selling, general and administrative expenses increased $13.0 million, or 5.7%, for the three months ended March 30, 2024, compared to the three months ended April 1, 2023. The increase was mainly due to higher employee compensation expenses, related to the timing of long-term incentive compensation accruals.

Other income, net, increased by $1.7 million for the three months ended March 30, 2024, compared to the three months ended April 1, 2023 mainly due to higher interest income earned on our cash and cash equivalents.

Interest expense increased by $0.7 million for the three months ended March 30, 2024, compared to the three months ended April 1, 2023. The following table sets forth the components of interest expense:

19

	Three Months Ended
(Amounts in thousands)	March 30, 2024		April 1, 2023
Interest on outstanding borrowings	$	83,928	$	80,179
Cash impact of interest rate swaps	(13,019)		(9,039)
Amortization of interest rate swap fair value(1)	2,962		2,995
Amortization of debt discount, debt issuance costs and purchase accounting fair value adjustment(1)	20,914		19,768
Other	35		208
Total interest expense	$	94,820	$	94,111

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

Foreign exchange (loss) gain was $4.0 million of loss for the three months ended March 30, 2024 compared to $2.0 million of gains for the three months ended April 1, 2023. The changes period over period are attributable to foreign exchange rate changes on intercompany loans based in Canadian currency.

Loss on extinguishment of debt included a loss of $0.6 million for the three months ended April 1, 2023, which resulted from the repurchase of our 6.125% Senior notes due January 2029 (“the 6.125% Senior Notes”) during the three months ended April 1, 2023. No repurchases were made during the three months ended March 30, 2024.

Income tax provision (benefit) increased by $23.9 million for the three-month period ended March 30, 2024 compared to the three months ended April 1, 2023 mainly due to increased state tax expense.

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.

Reconciliation of Net Loss to Adjusted EBITDA

The following table presents the reconciliation of net loss to Adjusted EBITDA:

	Three Months Ended
(Amounts in thousands)	March 30, 2024		April 1, 2023
Net loss	$	(118,573)	$	(28,815)

Gain on extinguishment of debt	—		563
Other income, net	(2,883)		(1,173)
Income tax provision (benefit)	15,334		(8,609)
(Loss) income from operations	(7,289)		54,060
Depreciation and amortization	94,317		72,662
Strategic development and acquisition related costs	4,074		7,622
Long-term incentive plan compensation(1)	10,514		(2,355)
Facility closure charges and employee separation	1,526		8,822
Other	3,799		369
Adjusted EBITDA	$	106,941	$	141,180

(1)Reflects expenses related to long-term incentive compensation plans, which primarily includes awards that were granted prior to the Merger (“Pre-Merger Awards”) and incentive unit grants that occurred subsequent to the Merger.

See Part I, Item 1, “Condensed Consolidated Financial Statements”, Note 12 — Reportable Segment and Geographical Information, 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.

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 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 30, 2024:

(Amounts in thousands)	Amount
Cash and cash equivalents	$	117,299
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	100,000
Letters of credit outstanding and priority payables	42,000
Net credit facility	895,000
Net liquidity	$	1,012,299

(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.

Cash Flows

	Three Months Ended
(Amounts in thousands)	March 30, 2024		April 1, 2023
Cash flows from operating activities	$	(163,697)	$	(110,571)
Cash flows from investing activities	$	(49,668)	$	(41,706)
Cash flows from financing activities	$	(138,875)	$	(22,000)

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 $(163.7) million for the three months ended March 30, 2024, a decrease from the $(110.6) million used in operations in the prior year. Lower volumes, higher core working capital, consisting of accounts receivable, inventories and accounts payable, were offset by the timing of incentive compensation plan payouts and the impact of the acquisitions.

23

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 $(49.7) million for the three months ended March 30, 2024 compared to $(41.7) million used in investing activities for the three months ended April 1, 2023. The $8.0 million decrease is mainly driven by an increase in capital expenditures during the three months ended March 30, 2024 compared to the three months ended April 1, 2023.

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 $(138.9) million for the three months ended March 30, 2024 compared to $(22.0) million used in financing activities for the three months ended April 1, 2023. The increase of $116.9 million is mainly driven by the dividend payment of $231.6 million made to Camelot Parent, partially offset by $100.0 million in additional short-term borrowings during the three months ended March 30, 2024.

Contingent Liabilities and Commitments

Leases

We have leases for certain manufacturing, warehouse, distribution locations, offices, vehicles and equipment. As of March 30, 2024 the Company had total future lease payments of $617.2 million, with $74.3 million payable within 12 months.

Debt

We have certain long-term debt instruments outstanding. As of March 30, 2024 the Company had total future payments of $3.9 billion, with $129.0 million payable within 12 months. See Note 7 — Long-Term Debt in the Notes to the Condensed Consolidated Financial Statements for additional information.

Critical Accounting Estimates

There have been no material changes in our critical accounting policies and estimates during the three months ended March 30, 2024. Refer to the 2023 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 30, 2024. Refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 for a description of the Company’s market risks.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 30, 2024. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures by a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed with an objective to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding the required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Management believes that our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives and based on the evaluation of our disclosure controls and procedures as of March 30, 2024, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at such reasonable assurance level. 

24

Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 30, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceeding.

See Part I, Item 1, “Condensed Consolidated Financial Statements”, Note 13 — Commitments and Contingencies, which is incorporated herein by reference.

Item 1A. Risk Factors.

In addition to the information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed under “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “2023 Form 10-K”). The risks disclosed in the 2023 Form 10-K, and information provided elsewhere in this report, could materially affect our business, financial condition or results of operations. Additional risks and uncertainties not currently known, or that we currently deem to be immaterial, may materially adversely affect our business, financial condition or results of operations. We believe there have been no other material changes in our risk factors from those disclosed in the 2023 Form 10-K.

Basis of Presentation

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 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 into 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, 2023 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.

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.

Mar. 30, 2024

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Summary of 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 obsolete inventory; the impairment of goodwill and intangible assets; establishing useful lives for and evaluating the recovery of long-lived assets; recognizing the fair value of assets acquired and liabilities assumed in business combinations; determining the fair value of contingent considerations; 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.

The following table sets forth the components of cash and cash equivalents:

	March 30, 2024		December 31, 2023
Cash	$	117,299	$	228,975
Money market funds (Level 1 securities)	—		239,902
Total cash and cash equivalents	$	117,299	$	468,877

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 $6.4 million and $9.6 million at March 30, 2024 and December 31, 2023.

Fair Value Measurements

The carrying amounts of cash and cash equivalents, trade accounts receivable and accounts payable approximate fair value as of March 30, 2024 and December 31, 2023 given the instruments’ relatively short maturities. The carrying amounts of the indebtedness under revolving credit facilities approximate fair value as the interest rates are variable and reflective of market rates. Fair values for our other debt instruments are measured using Level 1 and Level 2 inputs. U.S. GAAP requires us to use valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized as follows:

Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets.

Level 2: Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities or market-corroborated inputs.

Level 3: Unobservable inputs for which there is little or no market data and which require us to develop our own assumptions about how market participants would price the assets or liabilities.

In connection with certain business acquisitions, the Company periodically enters into agreements that require us to pay additional consideration to the relevant seller. These payments are contingent on the achievement of specified EBITDA targets in periods subsequent to the acquisition. The fair value of contingent consideration is based on unobservable, or Level 3, inputs including a probability-weighted average payout approach. Contingent consideration obligations are measured at fair value each reporting period and any adjustments to fair value are recognized in earnings in the period they are identified. The Company has not made any changes to the methods used to determine the fair value of its contingent consideration obligations.

Recent Accounting Pronouncements

In November 2023, the FASB issued Accounting Standards Update (“ASU”) No. 2023-07, Improvements to Reportable Segment Disclosures (Topic 280). This ASU updates reportable segment disclosure requirements by requiring disclosures of significant reportable segment expenses that are regularly provided to the Chief Decision Maker (“CODM”) and included within each reported measure of a segment’s profit or loss. This ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources. The ASU is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Adoption of the ASU should be applied retrospectively to all prior periods presented in the financial statements. Early adoption is also permitted. The ASU will likely result in us including the additional required disclosures when adopted. We are currently evaluating the provisions of this ASU and expect to adopt them for the year ending December 31, 2024.

In December 2023, the FASB issued ASU 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.

Acquisitions 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. In December 2023, the Company completed the acquisition of the Eastern Architectural Systems (“EAS”) business, whose operations are included in the Company’s Aperture Solutions reportable segment. EAS is based in Ft. Myers, Florida and manufactures custom-made aluminum and vinyl impact windows and doors.

The total purchase price for these acquisitions was $234.9 million comprised of upfront cash payments of $217.7 million and earn-out contingent consideration of $16.8 million related to the MAC Metal transaction. The EAS transaction is subject to a final working capital adjustment. The purchase price of these acquisitions was provisionally allocated to the assets acquired and liabilities assumed, which related primarily to inventory of $15.9 million, property, plant and equipment of $21.3 million, goodwill of $87.5 million, intangible assets such as, customer lists and trademarks, of $73.4 million and $34.3 million, contingent consideration of $16.8 million and noncurrent deferred income tax liabilities of $12.3 million. The goodwill recorded is a result of expected synergies and other benefits that we believe will result from the integration of the acquisitions with our operations.

The MAC Metal acquisition earn-out is payable over two consecutive twelve-month periods, with the first period starting in the month following the close of the applicable acquisition and payments are based upon achieving certain adjusted EBITDA-based metrics, as defined in the purchase agreement. There was no change to the fair-value of the contingent consideration of $16.8 million, of which $7.8 million is recognized in other current liabilities and $9.0 million is recognized in other long-term liabilities on our Condensed Consolidated Balance Sheets at March 30, 2024.

2024 Pending Acquisition

In March 2024, the Company reached an agreement to acquire Harvey Building Products Corp. (“Harvey”), a manufacturer of high performing windows and doors, and its portfolio of industry leading brands: 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 United States (“U.S.”). The transaction is subject to regulatory approval and customary closing conditions and is expected to close in the second quarter of 2024. Upon closing, the business will be integrated into our Aperture Solutions reportable segment.

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 30, 2024.

Fair value at December 31, 2023 - Other assets, net	$	64,704
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.

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation

Share-Based Compensation

Pre-Merger Awards

In connection with the Merger in July 2022, under which Cornerstone Building Brands became a privately held company, unvested share-based compensation awards that were previously granted to key employees and executives were cancelled and converted into a contingent contractual right to receive a cash payment from the Company upon vesting. The Company had $27.6 million at December 31, 2023 and $3.0 million at March 30, 2024 classified as a current liability within employee-related liabilities on its Condensed Consolidated Balance Sheets. The Company paid out $24.7 million of cash to settle Pre-Merger Awards in March 2024.

The Company recognized $1.5 million as expense in the three months ended March 30, 2024 and a gain of $4.8 million for the three months ended April 1, 2023. These amounts are included in selling, general and administrative expense on the Condensed Consolidated Statements of Loss. The gain during the three months ended April 1, 2023 resulted from the Company updating its vesting expectations for certain performance share units.

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”). 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 30, 2024, 24,010 incentive units were granted at an average grant date fair value of $46.71 per incentive unit. For the three months ended March 30, 2024, the Company recognized $1.6 million of expense from incentive units and the Company estimates that the unrecognized expense is expected to be recognized over a weighted-average period of 3.6 years totaling $29.5 million. During the three months ended April 1, 2023, the Company recognized $2.5 million of expense related to incentive units.

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, the Chief Executive Officer, reviews financial information presented on a consolidated basis, accompanied by information about our five operating segments, for the purposes of allocating resources and evaluating financial performance. The Company is organized into three reportable segments: Aperture Solutions, Surface Solutions and Shelter Solutions, which 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 and distribution centers. The Company defines low-rise commercial construction as building applications of up to five stories.

Management monitors the operational results of its reportable segments separately for purposes of making decisions about resources and evaluating performance. Management 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 revenues or expenses are eliminated in consolidation.

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.

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 $8.5 million as of March 30, 2024 and $8.8 million as of December 31, 2023 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. In January 2023, purported former stockholders filed two 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. The Company intends to vigorously defend against these claims. The Company cannot predict with any degree of certainty the outcome of these matters or determine the extent of any potential liabilities. The Company also cannot provide an estimate of the possible loss or range of loss.

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, attorneys’ fees, expenses, and costs. On December 8, 2023, the defendants moved to dismiss the operative complaint, and, in the alternative, to stay the litigation. 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. The Company does not believe, based on currently available information, that the outcome of these proceedings will have a material adverse effect on its financial condition.

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, 2023 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.

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 obsolete inventory; the impairment of goodwill and intangible assets; establishing useful lives for and evaluating the recovery of long-lived assets; recognizing the fair value of assets acquired and liabilities assumed in business combinations; determining the fair value of contingent considerations; 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. The Company’s allowance for expected credit losses was $6.4 million and $9.6 million at March 30, 2024 and December 31, 2023.

Fair Value Measurements

Fair Value Measurements

The carrying amounts of cash and cash equivalents, trade accounts receivable and accounts payable approximate fair value as of March 30, 2024 and December 31, 2023 given the instruments’ relatively short maturities. The carrying amounts of the indebtedness under revolving credit facilities approximate fair value as the interest rates are variable and reflective of market rates. Fair values for our other debt instruments are measured using Level 1 and Level 2 inputs. U.S. GAAP requires us to use valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized as follows:

Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets.

Level 2: Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities or market-corroborated inputs.

Level 3: Unobservable inputs for which there is little or no market data and which require us to develop our own assumptions about how market participants would price the assets or liabilities.

In connection with certain business acquisitions, the Company periodically enters into agreements that require us to pay additional consideration to the relevant seller. These payments are contingent on the achievement of specified EBITDA targets in periods subsequent to the acquisition. The fair value of contingent consideration is based on unobservable, or Level 3, inputs including a probability-weighted average payout approach. Contingent consideration obligations are measured at fair value each reporting period and any adjustments to fair value are recognized in earnings in the period they are identified. The Company has not made any changes to the methods used to determine the fair value of its contingent consideration obligations.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In November 2023, the FASB issued Accounting Standards Update (“ASU”) No. 2023-07, Improvements to Reportable Segment Disclosures (Topic 280). This ASU updates reportable segment disclosure requirements by requiring disclosures of significant reportable segment expenses that are regularly provided to the Chief Decision Maker (“CODM”) and included within each reported measure of a segment’s profit or loss. This ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources. The ASU is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Adoption of the ASU should be applied retrospectively to all prior periods presented in the financial statements. Early adoption is also permitted. The ASU will likely result in us including the additional required disclosures when adopted. We are currently evaluating the provisions of this ASU and expect to adopt them for the year ending December 31, 2024.

In December 2023, the FASB issued ASU 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.
