Notes to Condensed Consolidated Financial Statements

(Unaudited; in millions, except per share amounts or otherwise indicated)

1. Company Overview

Beacon Roofing Supply, Inc. (“Beacon” or the “Company”) was incorporated in the state of Delaware on July 16, 1997 and is the largest publicly traded distributor of roofing materials and complementary building products, such as siding and waterproofing, in North America.

The Company operates its business primarily under the trade name “Beacon Building Products” and services customers in all 50 states throughout the U.S. and seven provinces in Canada. The Company’s material subsidiaries are Beacon Sales Acquisition, Inc. and Beacon Roofing Supply Canada Company.

2. Summary of Significant Accounting Policies

Basis of Presentation

The Company prepared the condensed consolidated financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and the requirements of the Securities and Exchange Commission (“SEC”). As permitted under those rules, certain footnotes or other financial information have been condensed or omitted. Certain prior period amounts have been reclassified to conform to current period presentation.

The balance sheet as of March 31, 2023 has been presented for a better understanding of the impact of seasonal fluctuations on the Company’s financial condition. The three-month periods ended March 31, 2024 and 2023 each had 64 business days.

In management’s opinion, the unaudited condensed consolidated financial statements include all normal and recurring adjustments that are considered necessary for the fair presentation of the Company’s financial position and operating results. The results for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the twelve months ending December 31, 2024.

These unaudited condensed consolidated financial statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in the Company’s most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Recent Accounting Pronouncements — Not Yet Adopted

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements – Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative.” This standard affects a wide variety of Topics in the Codification. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. Early adoption is prohibited. The Company does not expect the adoption of this standard to have a material impact on the Company’s consolidated financial statements and related disclosures.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting - Improving Reportable Segment Disclosures (Topic 280).” The standard is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant expenses. The standard requires disclosures to include significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. The standard also requires all annual disclosures currently required by ASC Topic 280 to be included in interim periods. This standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures,” a final standard on improvements to income tax disclosures. The standard requires disaggregated information about a registrant's effective tax rate reconciliation as well as information on income taxes paid. This standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted and should be applied prospectively. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

3. Acquisitions

The following table presents the Company’s acquisitions between January 1, 2023 and March 31, 2024. The Company acquired 100% of the equity or substantially all of the net assets in each case. The Company has not provided pro forma results of operations for any of the transactions below, as the transactions individually and in the aggregate for the respective year are not material to the Company. The results of operations for these transactions are included in the Company’s condensed consolidated statements of operations from the date of the acquisition (dollars in millions):

In each company’s respective twelve months prior to being acquired by Beacon, the companies listed above produced aggregate annual sales of approximately $318.0 million. The total transaction costs incurred by the Company for these acquisitions for the three months ended March 31, 2024 were $2.0 million. Of the $92.0 million of goodwill recognized for these acquisitions, $51.7 million is deductible for tax purposes.

Total net sales	$	1,701.0	$	31.3	$	1,732.3

5. Net Income (Loss) Per Common Share

Basic net income (loss) per common share is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for common share equivalents or

9

the conversion of Preferred Stock (as defined below) when outstanding during the period. Common share equivalents consist of the incremental common shares issuable upon the exercise of stock options and vesting of restricted stock unit (“RSU”) awards. Diluted net income (loss) per common share is calculated by dividing net income (loss) attributable to common stockholders by the fully diluted weighted-average number of common shares outstanding during the period.

In connection with the acquisition of Allied Building Products Corp. on January 2, 2018, the Company completed the sale of 400,000 shares of Series A Cumulative Convertible Participating Preferred Stock, par value $0.01 per share (the “Preferred Stock”), with an aggregate liquidation preference of $400.0 million, at a purchase price of $1,000 per share, to CD&R Boulder Holdings, L.P. (“CD&R Holdings”).

On July 31, 2023 (the “Repurchase Date”), the Company repurchased (the “Repurchase”) all 400,000 issued and outstanding shares of the Preferred Stock held by CD&R Holdings (the shares of Preferred Stock held by CD&R Holdings, the “Shares”) pursuant to a letter agreement dated July 6, 2023 (the “Repurchase Letter Agreement”) in cash for $805.4 million, including $0.9 million of accrued but unpaid dividends as of such date (the “Repurchase Price”). In connection with the Repurchase, CD&R Holdings agreed that for as long as Philip Knisely or Nathan Sleeper remained a member of the Company’s Board and for a period of six months thereafter, the customary voting, standstill, and transfer restrictions set forth in the original Investment Agreement with respect to the Preferred Stock will continue to apply to CD&R Holdings and its related fund in accordance with their terms. Following the closing of the Repurchase, Mr. Sleeper resigned from the Company’s Board and Mr. Knisely remained a member of the Company’s Board until his resignation on January 23, 2024.

The aggregate Repurchase Price and related transaction fees and expenses were financed by a combination of proceeds from the 2030 Senior Notes, which are further described in Note 11, as well as the 2026 ABL and cash on hand.

On and after the Repurchase Date, all dividends and distributions ceased to accrue on the Shares, the repurchased Shares are no longer deemed outstanding, and all rights of CD&R Holdings with respect to the repurchased Shares terminated.

Before the Repurchase occurred, the Preferred Stock was convertible perpetual participating preferred stock of the Company, and conversion of the Preferred Stock into $0.01 par value shares of the Company’s common stock would have been at a conversion price of $41.26 per share (or 9,694,619 shares of common stock). The Preferred Stock accumulated dividends at a rate of 6.0% per annum (payable quarterly in cash or in-kind, subject to certain conditions). The Preferred Stock was not mandatorily redeemable; therefore, it was classified as mezzanine equity in the Company’s condensed consolidated balance sheets. Holders of Preferred Stock would have participated in dividends on an as-converted basis if declared on common shares. As a result, Preferred Stock was classified as a participating security and thereby required the allocation of income that would have otherwise been available to common stockholders when calculating net income (loss) per common share.

For periods in which Preferred Stock is outstanding, diluted net income (loss) per common share is calculated by utilizing the most dilutive result of the if-converted and two-class methods. In both methods, net income (loss) attributable to common stockholders and the weighted-average common shares outstanding are adjusted to account for the impact of the assumed issuance of potential common shares that are dilutive, subject to dilution sequencing rules.

10

The following table presents the components and calculations of basic and diluted net income (loss) per common share (in millions, except per share amounts; certain amounts may not recalculate due to rounding):

	Three Months Ended March 31,
	2024		2023
Numerator:
Net income (loss)	$	5.6	$	24.8
Dividends on Preferred Stock	—		(6.0)
Undistributed income allocated to participating securities	—		(2.5)
Net income (loss) attributable to common stockholders – Basic and Diluted	$	5.6	$	16.3
Denominator:
Weighted-average common shares outstanding – Basic	63.6		64.3
Effect of common share equivalents	1.2		1.3
Weighted-average common shares outstanding – Diluted	64.8		65.6
Net income (loss) per common share:
Basic	$	0.09	$	0.25
Diluted	$	0.09	$	0.25

The following table includes the number of shares that may be dilutive common shares in the future (except for the Preferred Stock, which was redeemed in July 2023 and therefore has no dilutive impact in the future as of March 31, 2024). These shares were not included in the computation of diluted net income (loss) per common share because the effect was either anti-dilutive or the requisite performance conditions were not met (in millions):

	Three Months Ended March 31,
	2024	2023
Stock options	0.0	0.2
Restricted stock units	0.0	0.1
Preferred Stock	—	9.7
Employee Stock Purchase Plan	0.1	—

6. Stock-based Compensation

On December 23, 2019, the Board of Directors of the Company (the “Board”) approved the Beacon Roofing Supply, Inc. Second Amended and Restated 2014 Stock Plan (the “2014 Plan”). On February 11, 2020, the stockholders of the Company approved an additional 4,850,000 shares to be reserved for issuance under the 2014 Plan. The 2014 Plan, which was originally approved by the stockholders on February 12, 2014, provides for discretionary awards of stock options, stock awards, restricted stock units, and stock appreciation rights to selected employees and non-employee directors. The 2014 Plan mandates that all shares underlying lapsed, forfeited, expired, terminated, cancelled and withheld awards, including those from the predecessor plan, be returned to the 2014 Plan and made available for issuance. As of March 31, 2024, there were 2,717,332 shares of common stock available for issuance pursuant to the 2014 Plan. The 2014 Plan is the only plan maintained by the Company pursuant to which equity awards are granted.

All unvested employee equity awards contain a “double trigger” change in control mechanism to the extent such employee equity award is continued or assumed after a change in control. If an award is not continued or assumed by a public company in an equitable manner, such award shall become vested immediately prior to a change in control (in the case of a restricted stock unit award with performance conditions at the then-calculable payout percentage for any completed annual performance periods and at 100% for any annual performance periods not yet calculable, and in the case of a restricted stock unit award with market conditions at 100% of the award then earned but not then vested). If an award is so continued or assumed, vesting will continue in accordance with the terms of the award, unless there is a qualifying termination (without cause or for good reason) within one-year following the change in control, in which event the award shall immediately become vested (in the case of a restricted stock unit award with performance conditions at the then-calculable payout percentage for any completed annual performance periods and at 100% for any annual performance periods not yet calculable, and in the case of a restricted stock unit award with market conditions at 100% of the award then earned but not then vested).

Stock Options

Non-qualified stock options generally expire 10 years after the grant date and, except under certain conditions, the options are subject to continued employment and vest in three annual installments over the three-year period following the grant date.

The fair values of the options granted for the periods presented were estimated on the dates of grants using the Black-Scholes option-pricing model with the following weighted-average assumptions:

	Three Months Ended March 31,
	2024		2023
Risk-free interest rate	4.12	%	4.26	%
Expected volatility	48.05	%	49.92	%
Expected life (in years)	5.08		5.12

1.Aggregate intrinsic value represents the difference between the closing fair value of the underlying common stock and the exercise price of outstanding, in-the-money options on the date of measurement.

During the three months ended March 31, 2024 and 2023, the Company recorded stock-based compensation expense related to stock options of $1.0 million and $0.9 million, respectively. During the three months ended March 31, 2024 and 2023, the Company recognized a tax benefit related to stock-based compensation expense related to stock options of $1.3 million and $0.4 million, respectively.

As of March 31, 2024, there was $6.7 million of unrecognized compensation expense related to unvested stock options, which is expected to be recognized over a weighted-average period of 2.1 years. The following table summarizes additional information on stock options (in millions, except per share amounts):

Total grant date fair value of stock options vested	$	2.7	$	1.8
Total intrinsic value of stock options exercised	$	6.4	$	3.3

Restricted Stock Units

Time-based RSU awards granted to employees are subject to continued employment and generally vest on the third anniversary of the grant date. The Company also grants certain RSU awards to management that additionally may contain market or performance conditions. Market conditions are incorporated into the grant date fair value of the management awards with market conditions using a Monte Carlo valuation model. Compensation expense for management awards with market conditions is recognized over the service period and is not reversed if the market condition is not met. For awards with performance conditions, the actual number of awards that will vest can range from 0% to 200% of the original grant amount, depending upon actual Company performance below or above

12

the established performance metric targets. At each reporting date, the Company estimates performance in relation to the defined targets when determining the projected number of management awards with performance conditions that are expected to vest and calculating the related stock-based compensation expense. Management awards with performance conditions are amortized over the service period if, and to the extent that, it is determined that achievement of the performance condition is probable. If awards with market, performance and/or service conditions are forfeited due to failure to achieve performance conditions or failure to satisfy service conditions, any previously recognized expense for such awards is reversed.

RSUs granted to non-employee directors are subject to continued service and vest on the first anniversary of the grant date (except under certain conditions). Generally, the common shares underlying the RSUs are not eligible for distribution until the non-employee director’s service on the Board has terminated, and for non-employee director RSU grants made prior to fiscal year 2014, the share distribution date is six months after the director’s termination of service on the Board. Any non-employee directors who have Beacon equity holdings (defined as common stock and outstanding vested equity awards) with a total fair value that is greater than or equal to five times the annual Board cash retainer may elect to have any future RSU grants settle simultaneously with vesting.

The following table summarizes all RSU activity for the three months ended March 31, 2024 (in millions, except grant date fair value amounts):

	RSUs Outstanding	Weighted-Average Grant Date Fair Value
Balance as of December 31, 2023	1.2	$	53.14

1.As of March 31, 2024, outstanding awards with performance conditions were expected to vest at less than 100% of their original grant amount.

During the three months ended March 31, 2024 and 2023, the Company recorded stock-based compensation expense related to RSUs of $5.8 million and $5.1 million, respectively. During the three months ended March 31, 2024 and 2023, the Company recognized a tax benefit related to stock-based compensation expense related to RSUs of $1.3 million and $0.1 million, respectively.

As of March 31, 2024, there was $46.0 million of unrecognized compensation expense related to unvested RSUs (including unrecognized expense for RSUs with performance conditions at their estimated value as of March 31, 2024), which is expected to be recognized over a weighted-average period of 2.3 years.

Employee Stock Purchase Plan

On March 20, 2023, the Board adopted the Company’s 2023 Employee Stock Purchase Plan (the “ESPP”), subject to stockholder approval, which was subsequently obtained on May 17, 2023 in conjunction with the 2023 Annual Meeting of Stockholders. The ESPP allows eligible employees to acquire shares of the Company’s common stock through payroll deductions over six-month offering periods. The purchase price per share is equal to 85% of the lesser of (1) the fair market value of a share of the Company’s common stock on the offering date, defined as the first trading day of the offering period, or (2) the fair market value of a share of the Company’s common stock on the purchase date, defined as the last trading day of the offering period; provided that the purchase price is not less than the $0.01 par value per share of the common stock. Participant purchases are limited to a maximum of $12,500 worth of stock per offering period (or $25,000 per calendar year). The Company is authorized to grant up to 1,000,000 shares of its common stock under the ESPP.

During the three months ended March 31, 2024, employees purchased approximately 58.0 thousand shares at a per share price of $70.86. As of March 31, 2024, there were approximately 942.0 thousand shares of common stock available for issuance pursuant to

13

the Company’s ESPP. During the three months ended March 31, 2024, the Company recorded stock-based compensation expense related to the ESPP of $0.6 million.

7. Share Repurchase Program

On February 24, 2022, the Company announced a new share repurchase program (the “Repurchase Program”), pursuant to which the Company may purchase up to $500.0 million of its common stock. On February 23, 2023, the Company announced that its Board authorized and approved an increase of the Repurchase Program by approximately $387.9 million, permitting future share repurchases of $500.0 million after considering actual share repurchases as of such re-authorization date.

Share repurchases under the Repurchase Program may be made from time to time through various means, including open market purchases (including block trades), privately negotiated transactions, accelerated share repurchase transactions (“ASR”) or through a series of forward purchase agreements, option contracts or similar agreements and contracts (including Rule 10b5-1 plans) adopted by the Company, in each case in accordance with the rules and regulations of the SEC, including, if applicable, Rule 10b-18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The timing, volume, and nature of share repurchases pursuant to the Repurchase Program are at the discretion of management and may be suspended or discontinued at any time. Shares repurchased under the Repurchase Program are retired immediately and are included in the category of authorized but unissued shares. Direct and incremental costs associated with the Repurchase Program are deferred and included as a component of the purchase price. The excess of the purchase price over the par value of the common shares is reflected in retained earnings.

The following table sets forth the Company’s share repurchases (in millions, except per share data):

	Three Months Ended March 31,
	2024		2023

Debt Refinancing

In May 2021, the Company entered into various financing arrangements to refinance certain debt instruments to take advantage of lower market interest rates for the Company’s fixed rate indebtedness and to extend maturities (the “2021 Debt Refinancing”). The transactions included a new $350.0 million issuance of senior notes (the “2029 Senior Notes”). In addition, the Company entered into a second amended and restated credit agreement for its $1.30 billion asset-based revolving line of credit (the “2026 ABL”), and an amended and restated term loan credit agreement for a term loan of $1.00 billion (the “2028 Term Loan”), which together are defined as the “Senior Secured Credit Facilities.”

On May 19, 2021, the Company used the net proceeds from the 2029 Senior Notes offering, together with cash on hand and borrowings under the Senior Secured Credit Facilities, to redeem all $1.30 billion aggregate principal amount outstanding of the Company’s 4.875% Senior Notes due 2025 at a redemption price of 102.438%, to refinance all outstanding borrowings under the Company’s previous term loan, and to pay all related accrued interest, fees and expenses.

In March 2024, the Company entered into a financing arrangement to refinance the 2028 Term Loan resulting in an increase in the outstanding principal balance from $975.0 million to $1.275 billion at March 31, 2024. Refer to the discussion below for additional information regarding the refinancing.

2029 Senior Notes

On May 10, 2021, the Company and certain subsidiaries of the Company as guarantors completed a private offering of $350.0 million aggregate principal amount of 4.125% senior unsecured notes due 2029 at an issue price equal to par. The 2029 Senior Notes mature on May 15, 2029 and bear interest at a rate of 4.125% per annum, payable on May 15 and November 15 of each year, which commenced on November 15, 2021. The 2029 Senior Notes are fully and unconditionally guaranteed, on a joint and several basis, by certain of the Company’s active United States subsidiaries.

16

The 2029 Senior Notes and related subsidiary guarantees were offered and sold in a private transaction exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), to qualified institutional buyers in accordance with Rule 144A under the Securities Act and to non-U.S. persons outside of the United States pursuant to Regulation S under the Securities Act. The 2029 Senior Notes and related subsidiary guarantees have not been, and will not be, registered under the Securities Act or the securities laws of any state or other jurisdiction, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and other applicable securities laws.

The Company capitalized debt issuance costs of $4.0 million related to the 2029 Senior Notes, which are being amortized over the term of the financing arrangements.

As of March 31, 2024, the outstanding balance on the 2029 Senior Notes, net of $2.6 million of unamortized debt issuance costs, was $347.4 million.

2026 ABL

On May 19, 2021, the Company entered into a $1.30 billion senior secured asset-based revolving credit facility with Wells Fargo Bank, N.A. and a syndicate of other lenders. The 2026 ABL provides for revolving loan commitments in both the United States in an amount up to $1.25 billion (“2026 U.S. Revolver”) and Canada in an amount up to $50.0 million (“2026 Canada Revolver”) (as such amounts may be reallocated pursuant to the terms of the 2026 ABL). The 2026 ABL has a maturity date of May 19, 2026. The 2026 ABL has various borrowing tranches with an interest rate based, at the Company’s option, on a base rate, plus an applicable margin, or a reserve adjusted LIBOR rate, plus an applicable margin. The applicable margin for borrowings is based on the Company’s quarterly average excess availability as determined by reference to a borrowing base and ranges from 0.25% to 0.75% per annum in the case of base rate borrowings and 1.25% to 1.75% per annum in the case of LIBOR borrowings. The unused commitment fees on the 2026 ABL are 0.20% per annum.

On June 6, 2023, the Company entered into Amendment No. 2 to the 2026 ABL (the “2026 ABL Amendment No. 2”) with Wells Fargo Bank, N.A., as administrative agent and collateral agent, and the lenders party thereto. The 2026 ABL Amendment No. 2, among other things, (i) replaced the LIBOR interest rate index and its related borrowing mechanics under the 2026 ABL with a SOFR interest rate index and its related borrowing mechanics, and (ii) updated certain other provisions of the 2026 ABL to reflect the transition from LIBOR to SOFR. Except as amended by the 2026 ABL Amendment No. 2, the remaining terms of the 2026 ABL remain in full force and effect.

The 2026 ABL contains a springing financial covenant that requires a minimum 1.00:1.00 Fixed Charge Coverage Ratio (consolidated EBITDA less capital expenditures to fixed charges, each as defined in the 2026 ABL credit agreement) as of the end of each fiscal quarter (in each case, calculated on a trailing four fiscal quarter basis). The covenant would become operative if the Company failed to maintain a specified minimum amount of availability to borrow under the 2026 ABL, which was not applicable to the Company as of March 31, 2024.

In addition, the Senior Secured Credit Facilities and the 2029 Senior Notes (as well as the 2030 Senior Notes and the 2026 Senior Notes, each as defined below) are subject to negative covenants that, among other things and subject to certain exceptions, limit the Company’s ability and the ability of its restricted subsidiaries to: (i) incur indebtedness (including guarantee obligations); (ii) incur liens; (iii) engage in mergers or other fundamental changes; (iv) dispose of certain property or assets; (v) make certain payments, dividends or other distributions; (vi) make certain acquisitions, investments, loans and advances; (vii) prepay certain indebtedness; (viii) change the nature of their business; (ix) engage in certain transactions with affiliates; (x) engage in sale-leaseback transactions; and (xi) enter into certain other restrictive agreements. The 2026 ABL is secured by a first priority lien over substantially all of the Company’s and each guarantor’s accounts and other receivables, chattel paper, deposit accounts (excluding any such account containing identifiable proceeds of Term Priority Collateral (as defined below)), inventory, and, to the extent related to the foregoing and other ABL Priority Collateral, general intangibles (excluding equity interests in any subsidiary of the Company and all intellectual property), instruments, investment property (but not equity interests in any subsidiary of the Company), commercial tort claims, letters of credit, supporting obligations and letter of credit rights, together with all books, records and documents related to, and all proceeds and products of, the foregoing, subject to certain customary exceptions (the “ABL Priority Collateral”), and a second priority lien over substantially all of the Company’s and each guarantor’s other assets, including all of the equity interests of any subsidiary held by the Company or any guarantor, subject to certain customary exceptions (the “Term Priority Collateral”). Beacon Sales Acquisition, Inc., a Delaware corporation and subsidiary of the Company, is a U.S. Borrower under the 2026 ABL and Beacon Roofing Supply Canada Company, an unlimited liability company organized under the laws of Nova Scotia and subsidiary of the Company, is a Canadian borrower under the 2026 ABL. The 2026 ABL is fully and unconditionally guaranteed, on a joint and several basis, by the Company’s active U.S. subsidiaries.

The Company capitalized debt issuance costs of $8.3 million related to the 2026 ABL, which are being amortized over the term of the financing arrangements.

17

As of March 31, 2024, the outstanding balance on the 2026 ABL, net of $3.5 million of unamortized debt issuance costs, was $111.5 million. The Company also had outstanding standby letters of credit related to the 2026 U.S. Revolver in the amount of $15.8 million as of March 31, 2024.

2028 Term Loan

On May 19, 2021, the Company entered into a $1.00 billion senior secured term loan B facility with Citibank, N.A. and a syndicate of other lenders. The 2028 Term Loan requires quarterly principal payments in the amount of $2.5 million, with the remaining outstanding principal to be paid on its May 19, 2028 maturity date. The interest rate is based, at the Company’s option, on a base rate, plus an applicable margin, or a reserve adjusted LIBOR rate, plus an applicable margin. The applicable margin for the 2028 Term Loan ranges, depending on the Company’s consolidated total leverage ratio (consolidated total indebtedness to consolidated EBITDA, each as defined in the 2028 Term Loan credit agreement), from 1.25% to 1.50% per annum in the case of base rate borrowings and 2.25% to 2.50% per annum in the case of LIBOR borrowings.

On July 3, 2023, the Company entered into Amendment No. 2 to the 2028 Term Loan (the “2028 Term Loan Amendment No. 2”) with Citibank, N.A., as administrative agent and collateral agent, and the lenders party thereto. The 2028 Term Loan Amendment No. 2, among other things, (i) replaced the LIBOR interest rate index and its related borrowing mechanics under the 2028 Term Loan with a SOFR interest rate index and its related borrowing mechanics, and (ii) updated certain other provisions of the 2028 Term Loan to reflect the transition from LIBOR to SOFR. Except as amended by the 2028 Term Loan Amendment No. 2, the remaining terms of the 2028 Term Loan remain in full force and effect.

On March 28, 2024. the Company entered into Amendment No. 3 to the 2028 Term Loan (the “2028 Term Loan Amendment No. 3”) with Citibank, N.A., as administrative agent and collateral agent, and the lenders party thereto, to refinance the 2028 Term Loan (the “2028 Term Loan Refinancing”). The 2028 Term Loan Amendment No. 3, among other things, (i) increases the aggregate outstanding amount of outstanding term loans to $1.275 billion, (ii) reduces the interest rate to a rate per annum equal to Term SOFR with a 0.00% floor, plus a margin equal to 2.00%, and (iii) increases the required quarterly principal payments from $2.5 million to $3.2 million starting March 31, 2024. Except as amended by the 2028 Term Loan Amendment No. 3, the remaining terms of the 2028 Term Loan remain in full force and effect.

The 2028 Term Loan Refinancing had certain lenders who also participated in previous financing arrangements entered into by the Company; therefore, a portion of the transaction was accounted for as either a debt extinguishment or debt modification. The Company recognized a loss on debt extinguishment totaling $2.4 million during the three months ended March 31, 2024. In addition, unamortized historical debt issuance costs of $9.7 million and new debt issuance costs of $0.1 million related to the 2028 Term Loan are being amortized over the term of the financing arrangement.

The 2028 Term Loan is secured by a shared first-priority lien on the Term Priority Collateral and a shared second-priority lien on the ABL Priority Collateral. Certain excluded assets will not be included in the Term Priority Collateral and the ABL Priority Collateral. The 2028 Term Loan is fully and unconditionally guaranteed, on a joint and several basis, by certain of the Company’s active U.S. subsidiaries.

On March 16, 2023, the Company novated and amended its interest rate swap agreement related to the 2028 Term Loan. For additional information, see Note 17.

As of March 31, 2024, the outstanding balance on the 2028 Term Loan, net of $9.8 million of unamortized debt issuance costs, was $1.27 billion.

2030 Senior Notes

On July 31, 2023, the Company, and certain subsidiaries of the Company as guarantors, completed a private offering of $600.0 million aggregate principal amount of 6.500% Senior Secured Notes due 2030 (the “2030 Senior Notes”) at an issue price equal to par. The 2030 Senior Notes mature on August 1, 2030 and bear interest at a rate of 6.500% per annum, payable on February 1 and August 1 of each year, commencing on February 1, 2024.

The 2030 Senior Notes are fully and unconditionally guaranteed, on a joint and several basis, by certain of the Company’s active U.S. subsidiaries.

The 2030 Senior Notes and related subsidiary guarantees were offered and sold in a private transaction exempt from the registration requirements of the Securities Act, to qualified institutional buyers in accordance with Rule 144A under the Securities Act and to non-U.S. persons outside of the United States pursuant to Regulation S under the Securities Act. The 2030 Senior Notes and related subsidiary guarantees have not been, and will not be, registered under the Securities Act or the securities laws of any state or other jurisdiction, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and other applicable securities laws.

The 2026 Senior Notes mature on November 15, 2026 and bear interest at a rate of 4.50% per annum, payable on May 15 and November 15 of each year, commencing on May 15, 2020. The 2026 Senior Notes and related subsidiary guarantees are secured by a shared first-priority lien on the Term Priority Collateral and a shared second-priority lien on the ABL Priority Collateral. Certain excluded assets will not be included in the Term Priority Collateral and the ABL Priority Collateral. The 2026 Senior Notes are fully and unconditionally guaranteed, on a joint and several basis, by certain of the Company’s active U.S. subsidiaries.

The 2026 Senior Notes and related subsidiary guarantees were offered and sold in a private transaction exempt from the registration requirements of the Securities Act, to qualified institutional buyers in accordance with Rule 144A under the Securities Act and to non-U.S. persons outside of the United States pursuant to Regulation S under the Securities Act. The 2026 Senior Notes and related subsidiary guarantees have not been, and will not be, registered under the Securities Act or the securities laws of any state or other jurisdiction, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and other applicable securities laws.

On October 28, 2019, the Company used the net proceeds from the offering, together with cash on hand and available borrowings under the Company’s previous asset-based revolving credit facility, to redeem all $300.0 million aggregate principal amount outstanding of the Company’s 6.375% Senior Notes due 2023.

The Company capitalized debt issuance costs of $4.7 million related to the 2026 Senior Notes, which are being amortized over the term of the financing arrangements.

13. Commitments and Contingencies

The Company is subject to loss contingencies pursuant to various federal, state, and local environmental laws and regulations; however, the Company is not aware of any reasonably possible losses that would have a material impact on its results of operations, financial position, or liquidity. Potential environmental loss contingencies include possible obligations to remove or mitigate the effects on the environment of the placement, storage, disposal, or release of certain chemical or other substances by the Company or by other parties. Historically, environmental liabilities have not had a material impact on the Company’s results of operations, financial position, or liquidity.

The Company is subject to litigation and governmental investigations from time to time in the ordinary course of business; however, the Company does not expect the results, if any, to have a material adverse impact on its results of operations, financial position, or liquidity. The Company accrues a liability for legal claims when payments associated with the claims become probable and the costs can be reasonably estimated. The Company also considers whether an insurance recovery receivable is applicable and appropriate based on the specific legal claim. The actual costs of resolving legal claims and governmental investigations may be substantially higher or lower than the amounts accrued for those activities.

In December 2018, a Company vehicle was involved in an accident that resulted in a fatality. The estate of the decedent and two bystanders filed a lawsuit in October 2019 in the Fourth Judicial District Court for Utah County, Provo Division, against the driver and the Company. Trial was held in late August 2022; the jury determined that the truck driver was not liable for the accident. The plaintiffs filed post-trial motions seeking a judgment as a matter of law or for a new trial. In April 2023, the trial court ruled on the plaintiffs’ motions, granting plaintiffs judgment against the driver and ordering that the second phase of the trial proceed. On June 29, 2023, the Utah appeals court granted the Company’s petition for an interlocutory appeal. There is not a probable loss with respect to this matter and any potential loss in regard to this matter is not reasonably estimable. Accordingly, the Company has not accrued any amounts related to this matter within its financial statements as of March 31, 2024.

Total long-lived assets	$	889.2	$	837.4	$	786.3

16. Fair Value Measurement

As of March 31, 2024, the carrying amount of cash and cash equivalents, accounts receivable, prepaid and other current assets, accounts payable, and accrued expenses approximated fair value because of the short-term nature of these instruments. The Company measures its cash equivalents at amortized cost, which approximates fair value based upon quoted market prices (Level 1).

As of March 31, 2024, based upon recent trading prices (Level 2), the fair values of the Company’s $300.0 million 2026 Senior Notes, $350.0 million 2029 Senior Notes, and $600.0 million 2030 Senior Notes were $291.8 million, $318.1 million, and $608.3 million, respectively.

As of March 31, 2024, the fair value of the Company’s term loan and revolving lines of credit approximated the amount outstanding. The Company estimates the fair value of its term loan and revolving lines of credit by discounting the future cash flows of each instrument using estimated market rates of debt instruments with similar maturities and credit profiles (Level 3).

17. Financial Derivatives

The Company uses interest rate derivative instruments to manage the risk related to fluctuating cash flows from interest rate changes by converting a portion of its variable-rate borrowings into fixed-rate borrowings.

On September 11, 2019, the Company entered into two interest rate swap agreements to manage the interest rate risk associated with the variable rate on the Company’s previous term loan. Each swap agreement has a notional amount of $250.0 million. As part of the 2021 Debt Refinancing, Beacon refinanced its previous term loan, resulting in the issuance of the 2028 Term Loan; the two interest rate swaps were designed and executed such that they continue to hedge against a total notional amount of $500.0 million related to the refinanced 2028 Term Loan. One agreement (the “5-year swap”) was scheduled to expire on August 30, 2024 and swaps the thirty-day LIBOR with a fixed-rate of 1.49%. The second agreement (the “3-year swap”) expired on August 30, 2022 and swapped the thirty-day LIBOR with a fixed-rate of 1.50%. At the inception of the swap agreements, the Company determined that both swaps qualified for cash flow hedge accounting under ASC 815. Therefore, changes in the fair value of the swaps, net of taxes, were recognized in other comprehensive income each period, then reclassified into the condensed consolidated statements of operations as a component of interest expense, financing costs and other, net in the period in which the hedged transaction affects earnings.

On March 16, 2023, the Company novated its 5-year swap agreement to another counterparty and, in connection with such novation, amended the interest rate swap agreement. The amendment changed the index rate from LIBOR to SOFR, increased the total notional

21

amount of the interest rate swap to $500.0 million, and extended the termination date to March 31, 2027 (the “2027 interest rate swap”). Specifically, the fixed rate of 1.49% indexed to LIBOR was modified to 3.00% indexed to SOFR. The Company used a strategy commonly referred to as “blend and extend” which allows the asset position of the novated 5-year swap agreement of approximately $9.9 million to be effectively blended into the new 2027 interest rate swap agreement. As a result of this transaction, on March 16, 2023, the 5-year swap agreement was de-designated and the unrealized gain of $9.9 million included within accumulated other comprehensive income was frozen and will be ratably reclassified as a reduction to interest expense, financing costs and other, net over the original term of the 5-year swap, or through August 30, 2024 as the hedged transactions affect earnings. Additionally, the 2027 interest rate swap had a fair value of $9.9 million at inception and will be ratably recorded to accumulated other comprehensive income and reclassified to interest expense, financing costs and other, net over the term of the 2027 interest rate swap, or through March 31, 2027 as the hedged transactions affect earnings. At the inception of the 2027 interest rate swap, the Company determined that the swap qualified for cash flow hedge accounting under ASC 815. Therefore, changes in the fair value of the swap, net of taxes, will be recognized in other comprehensive income each period, then reclassified into the condensed consolidated statements of operations as a component of interest expense, financing costs and other, net in the period in which the hedged transaction affects earnings. The 2027 interest rate swap is the only swap agreement outstanding as of March 31, 2024.

The effectiveness of the outstanding 2027 interest rate swap will be assessed qualitatively by the Company during the life of the hedge by (i) comparing the current terms of the hedge with the related hedged debt to assure they continue to coincide and (ii) through an evaluation of the ability of the counterparty to the hedge to honor its obligations under the hedge. The Company performed a qualitative analysis as of March 31, 2024 and concluded that the outstanding 2027 interest rate swap continues to meet the requirements under ASC 815 to qualify for cash flow hedge accounting. As of March 31, 2024, the fair value of the 2027 interest rate swap, net of tax, was $12.9 million in favor of the Company.

During the three months ended March 31, 2024, the Company reclassified gains of $0.8 million out of accumulated other comprehensive income (loss) and to interest expense, financing costs and other, net. Approximately $9.6 million of net gains included in accumulated other comprehensive income (loss) at March 31, 2024 is expected to be reclassified into earnings within the next 12 months as interest payments are made on the Company’s Term Loan and amortization of the frozen AOCI on the 5-year swap and inception date fair value of the 2027 interest rate swap occurs. The Company records any differences paid or received on its interest rate hedges to interest expense, financing costs and other, net within the condensed consolidated statements of operations.

The fair value of the interest rate swap is determined through the use of a pricing model, which utilizes verifiable inputs such as market interest rates that are observable at commonly quoted intervals (generally referred to as the “forward curve”) for the full terms of the hedge agreements. These values reflect a Level 2 measurement under the applicable fair value hierarchy. The following table summarizes the combined fair values, net of tax, of the interest rate derivative instrument (in millions):

		Net Assets (Liabilities) as of
		March 31,		December 31,		March 31,
Instrument	Fair Value Hierarchy	2024		2023		2023

Overview

We are the largest publicly traded distributor of roofing materials and complementary building products, such as siding and waterproofing, in North America. We have served the building industry for over 90 years and as of March 31, 2024, we operated 542 branches throughout all 50 states in the U.S. and seven provinces in Canada. We offer one of the most extensive ranges of high-quality professional grade exterior products comprising over 130,000 SKUs, and we serve nearly 100,000 residential and non-residential customers who trust us to help them save time, work more efficiently, and enhance their businesses.

We are strategically focused on two core markets, residential and non-residential roofing. We also distribute complementary building products like siding and waterproofing that are often utilized by the roofing and other specialty contractors we serve. As a distributor, our national scale, networked model, and specialized capabilities are competitive advantages, providing strong value for both customers and suppliers. We intend to grow faster than the market by enhancing our customers’ experience, activating a comprehensive go-to-market strategy, and expanding our footprint organically and through acquisitions while also driving margin-enhancing initiatives.

Our differentiated service model is designed to solve customer needs. The scale of our business provides branch coverage, technology enablement, and investment in our team that is the foundation of customer service excellence. In addition, service is further enhanced by our Beacon OTC® Network, market-based sales teams, and national call center. We believe we also provide the most complete digital commerce platform in roofing distribution, creating value for customers who are able to operate their businesses more effectively and efficiently.

Our mission is to empower our customers to build more for their customers, businesses, and communities. Our project lifecycle support helps our customers find projects, land the job, do the work, and close projects out by providing guidance that allows our customers to deliver on project specifications and timelines that are critical to their success. Using an omni-channel approach and our PRO+ digital suite, we differentiate our services and drive customer retention. Our customer base is composed of professional contractors, home builders, building owners, lumberyards, and retailers across the U.S. and Canada who depend on reliable local access to exterior building products for residential and non-residential projects. Our customers vary in size, ranging from relatively small contractors to large contractors and builders that operate on a national scale.

On February 24, 2022, we announced our Ambition 2025 Value Creation Framework (“Ambition 2025”) to drive growth, enhance customer service, and expand our footprint in key markets, which included new Ambition 2025 financial targets and the Repurchase Program (as defined and further detailed below), as well as strategic deployment of capital on acquisitions and greenfields.

Specifically, since January 1, 2022 we have expanded our geographic footprint in key markets through the opening of 48 greenfield locations and acquisition of 50 total branches from 16 acquisitions. These greenfields and acquired branches contributed $95.1 million and $136.6 million to net sales in 2024, respectively, demonstrating our success in executing Ambition 2025. The scale we have

23

achieved from our expansion serves as a competitive advantage, allowing us to use our assets more efficiently, and manage our expenses to drive operating leverage. For additional information on our acquisition activity, see Note 3 in the Notes to the Condensed Consolidated Financial Statements.

The Ambition 2025 strategies are central to achieving sales growth, improving operational performance, and increasing profitability. Most importantly, our customers benefit from these initiatives as they are designed to make us more efficient and easier to do business with, differentiating our service from competitors. Our recent highlights in our pursuit of Ambition 2025 are further demonstrated by the following accomplishments during the three months ended March 31, 2024:

•7 branches acquired;

•3 new branch locations opened;

•digital sales 27.6% higher than the prior year; and

•continued improvements in the results of our branches falling in the bottom quintile of our financial performance metrics.

As of March 31, 2024, we operated 542 branches, which we designate as either standalone or co-located. A co-located branch shares all or a portion of a physical location with a standalone branch, but it records sales separately (to a different customer base and/or through different product offerings from the standalone branch) and generally operates with independent employees and inventory.

Preferred Stock Repurchase Agreement

On July 31, 2023 (the “Repurchase Date”), we repurchased (the “Repurchase”) all 400,000 issued and outstanding shares of Preferred Stock held by CD&R Holdings Boulder Holdings, L.P. (“CD&R Holdings,” and the shares of Preferred Stock held by CD&R Holdings, the “Shares”) pursuant to a letter agreement dated July 6, 2023 (the “Repurchase Letter Agreement”) in cash for $805.4 million, including $0.9 million of accrued but unpaid dividends as of such date (the “Repurchase Price”). In connection with the Repurchase, CD&R Holdings agreed that for as long as Philip Knisely or Nathan Sleeper remained a member of our Board and for a period of six months thereafter, the customary voting, standstill, and transfer restrictions set forth in the original Investment Agreement with respect to the Preferred Stock would continue to apply to CD&R Holdings and its related fund in accordance with their terms. Following the closing of the Repurchase, Mr. Sleeper resigned from our Board and Mr. Knisely remained a member of our Board until his resignation on January 23, 2024.

The aggregate Repurchase Price and related transaction fees and expenses were financed by a combination of proceeds from the 2030 Senior Notes, which are further described in Note 11 in the Notes to Condensed Consolidated Financial Statements, as well as the 2026 ABL and cash on hand.

On and after the Repurchase Date, all dividends and distributions ceased to accrue on the Shares, the repurchased Shares are no longer deemed outstanding, and all rights of CD&R Holdings with respect to the repurchased Shares terminated.

Classification of Branch Results

In managing our business, we consider all growth, including the opening of new branches (also referred to as greenfields), to be organic growth, unless it results from an acquisition. When we refer to organic growth, we include growth from existing branches and greenfields but exclude growth from acquired branches until they have been reclassified to existing as described further below.

During the fourth quarter of 2023, we revised our definition of when a branch classification changes from acquired to existing. Previously, the results of operations of branches were designated as acquired until they had been under our ownership for at least four full fiscal quarters at the start of the fiscal reporting period, after which such branches were classified as existing. Under our new definition, the results of operations of branches will be designated as acquired until they have been under our ownership and have contributed to our results of operations for at least 12 calendar months (inclusive of partial month activity), after which such branches are classified as existing. The effect of this change in definition is that the prior year results of operations for branches will be reclassified to existing when the comparable current month’s financial results are also classified as existing. As a result of this change, a branch’s results of operations can also now be classified as both acquired and existing in the same fiscal reporting period. We believes this change enhances comparability of branch results between periods and better demonstrates the economic impact of newly acquired branches on our financial results.

24

The following table illustrates the classification of financial results for branches acquired during the three months ended March 31, 2023:

Date Acquired	Company Name	Branches Acquired	Results of Operations Classified as Acquired	Results of Operations Classified as Existing
March 31, 2023	Al's Roofing Supply, Inc.	4	January 2024 - March 2024	None1
March 31, 2023	Prince Building Systems, LLC	1	January 2024 - March 2024	None1
January 4, 2023	First Coastal Exteriors, LLC	2	None	January 2023 - March 2023 January 2024 - March 2024

1.There were no sales during the three months ended March 31, 2023 for these acquisitions given March 31, 2023 was the last business day of the fiscal quarter ended March 31, 2023.

All branches acquired prior to January 1, 2023 are classified as existing and all branches acquired on or after March 31, 2023 are classified as acquired.

We also apply the same definition for determining when a branch classification changes from greenfield to existing (e.g., branches are designated as greenfields until they have been opened for at least 12 calendar months (inclusive of partial month activity), after which such branches are classified as existing). It should also be noted that greenfield branches incur limited operating costs prior to their open date for things such as lease costs and other costs incurred in getting the branch ready to open. All such costs incurred prior to the greenfield open date are also classified as greenfield in all periods when discussing our results of operations.

Total net sales	$	1,912.4	$	1,732.3	$	180.1	10.4	%

The increase in organic net sales was primarily driven by an increase in estimated organic volume of 6-7% due to strong residential and non-residential demand, as well as an increase in weighted-average selling price of 0-1%. Total net sales continued to benefit from greenfields and acquired branches as we execute on our Ambition 2025 plan.

We estimate the impact of inflation or deflation on our sales and gross profit by looking at changes in our average selling prices and gross margins (discussed below). To calculate approximate weighted average selling price and product cost changes, we review organic U.S. warehouse sales of the same items sold regionally period over period and normalize the data for non-representative outliers. To determine estimated volumes, we subtract the change in weighted average selling price, calculated as described above, from the total changes in net sales, excluding acquisitions and dispositions. As a result, and especially in high inflationary periods, the weighted average selling price and estimated volume changes may not be directly comparable to changes reported in prior periods.

The following table summarizes gross profit and gross margin by branch classification for the periods presented (in millions):

	Three Months Ended March 31,						Change1

27

Gross margin was 24.7% in 2024, down 0.8 percentage points from 25.5% in 2023. The year-over-year decrease in gross margin resulted from a modest weighted-average product cost increase of approximately 0-1% and a higher non-residential product mix, partially offset by a weighted-average selling price increase (calculated as described above) of approximately 0-1%.

Selling, General, and Administrative Expense

The following table summarizes selling, general, and administrative (“SG&A”) expense by branch classification for the periods presented (in millions):

	Three Months Ended March 31,						Change
	2024			2023			$		%
Organic SG&A
Existing	$	360.3		$	338.2		$	22.1	6.5	%
Greenfields	8.9			0.1			8.8		n/m
Total organic SG&A	369.2			338.3			30.9		9.1	%
Acquired	12.3			—			12.3		n/m
Total SG&A	$	381.5		$	338.3		$	43.2	12.8	%
Total SG&A as % of net sales	20.0		%	19.5		%

SG&A expense increased 12.8%, or $43.2 million, to $381.5 million in 2024, up from $338.3 million in 2023. The increase in organic SG&A expense was mainly influenced by the following factors:

•a $19.8 million increase in payroll and employee benefit costs, primarily due to increased headcount to drive and support growth, as well as wage inflation;

•a $3.7 million increase in warehouse operating costs, primarily due to an increase in branches since 2023; and

•a $2.4 million increase in selling costs, primarily due to an increase in fleet costs and advertising.

Depreciation Expense

Depreciation expense was $25.5 million in 2024, compared to $20.7 million in 2023. The comparative increase was primarily due to an increase in property and equipment as a result of new and acquired branches subsequent to 2023.

Amortization Expense

Amortization expense was $21.1 million in 2024, compared to $22.3 million in 2023. The modest comparative decrease was primarily due to previously acquired intangible assets becoming fully amortized, partially offset by amortization expense associated with new intangible assets as a result of acquisitions completed since 2023.

Interest Expense, Financing Costs and Other

Interest expense, financing costs and other, net was $38.6 million in 2024, compared to $27.8 million in 2023. The comparative increase was primarily due to higher average debt balances during the respective periods primarily as a result of the 2030 Senior Notes (as defined in Note 11 in the Notes to the Condensed Consolidated Financial Statements) issued in July 2023, and to a lesser extent, a higher weighted-average interest rate on our outstanding debt as a result of the repricing of our variable rate debt and a higher interest rate on our fixed rate 2030 Senior Notes relative to previously issued senior notes that carry a fixed rate.

Loss on Debt Extinguishment

Loss on debt extinguishment was $2.4 million in 2024 due to the refinancing of our 2028 Term Loan and includes the write-off of certain debt issuance costs attributable to extinguished lenders and certain non-creditor related fees.

Income Taxes

Income tax provision (benefit) was $(1.5) million in 2024, compared to $8.0 million in 2023. The comparative decrease in income tax provision was primarily due to lower pre-tax income coupled with an increase in the excess tax benefits of stock-based compensation during 2024. The effective tax rate, excluding discrete items, was 26.4% in 2024, compared to 26.3% in 2023. We expect our 2024 effective tax rate, excluding any discrete items that may arise during the tax year, will range from approximately 26.0% to 27.0%.

28

Net Income (Loss)/Net Income (Loss) Per Common Share

We calculate basic net income (loss) per common share by dividing net income (loss), less dividends on Preferred Stock and adjustments for participating securities for periods in which they are outstanding, by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per common share is calculated based upon the weighted-average common shares plus the effect of all potentially dilutive common share equivalents, except when the effect would be anti-dilutive. For periods in which Preferred Stock is outstanding, diluted net income (loss) per common share is calculated by utilizing the most dilutive result after applying and comparing the two-class method and if-converted method.

The following table presents all the components utilized to calculate basic and diluted net income (loss) per common share (in millions, except per share amounts; certain amounts may not recalculate due to rounding):

	Three Months Ended March 31,
	2024		2023

Non-GAAP Financial Measures

To provide investors with additional information regarding our financial results, we prepare certain financial measures that are not calculated in accordance with generally accepted accounting principles in the United States (“GAAP”), specifically:

•Adjusted Operating Expense. We define Adjusted Operating Expense as operating expense, excluding the impact of the adjusting items (as described below).

•Adjusted Net Income (Loss). We define Adjusted Net Income (Loss) as net income (loss), excluding the impact of the adjusting items (as described below).

•Adjusted EBITDA. We define Adjusted EBITDA as net income (loss), excluding the impact of interest expense (net of interest income), income taxes, depreciation and amortization, stock-based compensation, and the adjusting items (as described below).

We use these supplemental non-GAAP measures to evaluate financial performance, analyze the underlying trends in our business and establish operational goals and forecasts that are used when allocating resources. We expect to compute our non-GAAP financial measures consistently using the same methods each period.

We believe these non-GAAP measures are useful measures because they permit investors to better understand changes over comparative periods by providing financial results that are unaffected by certain items that are not indicative of ongoing operating performance.

While we believe that these non-GAAP measures are useful to investors when evaluating our business, they are not prepared and presented in accordance with GAAP, and therefore should be considered supplemental in nature. These non-GAAP measures should not be considered in isolation or as a substitute for other financial performance measures presented in accordance with GAAP. These non-GAAP financial measures may have material limitations including, but not limited to, the exclusion of certain costs without a corresponding reduction of net income for the income generated by the assets to which the excluded costs relate. In addition, these non-GAAP financial measures may differ from similarly titled measures presented by other companies.

29

Adjusting Items to Non-GAAP Financial Measures

The impact of the following expense (income) items is excluded from each of our non-GAAP measures (the “adjusting items”):

•Acquisition costs. Represent certain direct and incremental costs related to acquisitions, including: amortization of intangible assets; professional fees, branch integration expenses, travel expenses, employee severance and retention costs, and other personnel expenses classified as selling, general and administrative; gains/losses related to changes in fair value of contingent consideration or holdback liabilities; and amortization of debt issuance costs. Acquisition costs are impacted by the timing and size of the acquisitions. We exclude acquisition costs from our non-GAAP financial measures to provide a useful comparison of our operating results to prior periods and to our peer companies because such amounts vary significantly based on the magnitude of the acquisition and do not reflect our core operations.

•Restructuring costs. Represent costs stemming from headcount rationalization efforts and certain rebranding costs; impact of divestitures; amortization of debt issuance costs; debt refinancing and extinguishment costs; and abandoned lease costs. We exclude restructuring costs from our non-GAAP financial measures, as such items vary significantly based on the magnitude of the restructuring activity and also do not reflect expected future operating expenses. Additionally, these costs do not necessarily provide meaningful insight into the current or past core operations of our business.

The following table presents the pre-tax impact of the adjusting items on our condensed consolidated statements of operations for each of the periods indicated (in millions):

	Operating Expense				Non-Operating Expense
	SG&A		Amortization		Interest Expense		Other (Income) Expense		Total

Total adjusting items	$	2.2	$	22.3	$	1.3	$	—	$	25.8

1.Other (income) expense for the three months ended March 31, 2024 consists of a loss on debt extinguishment of $2.4 million as a result of the refinancing of our 2028 Term Loan, as discussed in Note 11 in the Notes to the Condensed Consolidated Financial Statements.

Seasonality and Quarterly Fluctuations

The demand for exterior building materials is closely correlated to both seasonal changes and unpredictable weather patterns, therefore demand fluctuations are expected.

In general, our net sales and net income are highest in quarters ending June 30, September 30, and December 31, which represent the peak months of construction and re-roofing. Conversely, we have historically experienced low net income levels or net losses in

31

quarters ending March 31, when winter construction cycles and cold weather patterns have an adverse impact on our customers’ ability to conduct their business.

Our balance sheet fluctuates throughout the year, driven by similar seasonal trends. We generally experience an increase in inventory and peak cash usage in the quarters ending March 31 and June 30, driven primarily by increased purchasing that is necessary to meet the rise in demand for our products during the warmer months. Accounts receivable, accounts payable, and cash collections are generally at their highest during the quarters ending June 30 and September 30, when sales are typically at their peak.

At times, we experience fluctuations in our financial performance that are driven by factors outside of our control, including the impact that severe weather events and unusual weather patterns may have on the timing and magnitude of demand and material availability.

Liquidity and Capital Resources

Liquidity is defined as the current amount of readily available cash and the ability to generate adequate amounts of cash to meet the current needs for cash. We assess our liquidity in terms of our cash and cash equivalents on hand and the ability to generate cash to fund our operating activities, taking into consideration available borrowings and the seasonal nature of our business.

Our principal sources of liquidity as of March 31, 2024 were our cash and cash equivalents of $134.6 million and our available borrowings of approximately $1.16 billion under our asset-based revolving lines of credit.

Significant factors which could affect future liquidity include the following:

•the adequacy of available bank lines of credit;

•the ability to attract long-term capital with satisfactory terms;

•cash flows generated from operating activities;

•working capital management;

•acquisitions;

•share repurchases; and

•capital expenditures.

Our primary capital needs are for working capital obligations and other general corporate purposes, including acquisitions, capital expenditures, and share repurchases. Our primary sources of working capital are cash from operations and bank borrowings. We have financed larger acquisitions through increased bank borrowings and the issuance of long-term debt and common or preferred stock. We then repay any such borrowings with cash flows from operations or subsequent financings. We have funded most of our capital expenditures with cash on hand, increased bank borrowings, or equipment financing, and then reduced those obligations with cash flows from operations. We may explore additional or replacement financing sources in order to bolster liquidity and strengthen our capital structure.

We believe we currently have adequate liquidity and availability of capital to fund our present operations, meet our commitments on our existing debt and fund anticipated growth, including expansion in existing and targeted market areas. We may seek additional acquisition opportunities from time to time, including as part of our Ambition 2025 initiative. If suitable acquisition opportunities or working capital needs arise that require additional financing, we believe that our financial position, credit profile, and earnings history provide a sufficient base for obtaining additional financing resources at reasonable rates and terms. We may also choose to issue additional shares of common stock or preferred stock in order to raise funds.

The following table summarizes our cash flows for the periods indicated (in millions):

	Three Months Ended March 31,
	2024		2023
Net cash provided by (used in) operating activities	$	(140.8)	$	101.2
Net cash provided by (used in) investing activities	(135.1)		(44.5)
Net cash provided by (used in) financing activities	327.1		(50.2)
Effect of exchange rate changes on cash and cash equivalents	(0.6)		—
Net increase (decrease) in cash and cash equivalents	$	50.6	$	6.5

32

Operating Activities

Net cash used in operating activities was $140.8 million in 2024, compared to net cash provided by operating activities of $101.2 million in 2023. Cash from operations decreased $242.0 million in 2024 primarily due to an incremental cash outflow of $233.9 million stemming from changes to our net working capital, mainly driven by unfavorable changes in cash flows related to inventories of $343.2 million, prepaid expenses and other current assets of $137.9 million, and accounts receivable of $47.0 million compared to the prior year, partially offset by a favorable change in cash flows related to accounts payable and accrued expenses of $295.8 million. As discussed above, we generally experience an increase in inventory and peak cash usage in the first quarter with 2024 representing the normalization of the timing of inventory purchases relative to 2023 where we proactively built-up inventory to mitigate risks associated with supply chain dynamics.

Investing Activities

Net cash used in investing activities was $135.1 million in 2024, compared to $44.5 million in 2023. Cash used in investing activities increased $90.6 million in 2024 primarily due to an increase in acquisitions and capital expenditures during the period. See Note 3 for more information.

Financing Activities

Net cash provided by financing activities was $327.1 million in 2024, compared to net cash used in financing activities of $50.2 million in 2023. Cash provided by financing activities increased $377.3 million in 2024 primarily due to the refinancing of our 2028 Term Loan resulting in an increase in principal balance of $300.0 million coupled with net borrowings under our revolving lines of credit compared to a net repayment in the prior year, partially offset by a decrease in share repurchases compared to the prior year.

Financing Arrangements

As of March 31, 2024, we had access to the following financing arrangements:

•the 2026 U.S. Revolver, an asset-based revolving line of credit in the U.S., in an amount up to $1.25 billion and with an outstanding balance (net of unamortized debt issuance costs) of $111.5 million;

•the 2026 Canada Revolver, an asset-based revolving line of credit in Canada, in an amount up to $50.0 million and with no outstanding balance;

•the 2028 Term Loan with an outstanding balance (net of unamortized debt issuance costs) of $1.27 billion; and

•three separate senior notes instruments, the 2030 Senior Notes, 2029 Senior Notes, and 2026 Senior Notes, with outstanding balances (net of unamortized debt issuance costs) of $592.6 million, $347.4 million, and $298.3 million, respectively.

See Note 11 in the Notes to Condensed Consolidated Financial Statements for additional information on our current financing arrangements.

Share Repurchase Program

On February 24, 2022, we announced a new share repurchase program (the “Repurchase Program”), pursuant to which we may purchase up to $500.0 million of our common stock. On February 23, 2023, we announced that our Board authorized and approved an increase of the Repurchase Program by approximately $387.9 million, permitting future share repurchases of $500.0 million after considering actual share repurchases as of such re-authorization date.

Share repurchases under the Repurchase Program may be made from time to time through various means, including open market purchases (including block trades), privately negotiated transactions, accelerated share repurchase (“ASR”) transactions or through a series of forward purchase agreements, option contracts or similar agreements and contracts (including Rule 10b5-1 plans) adopted by us, in each case in accordance with the rules and regulations of the SEC, including, if applicable, Rule 10b-18 of the Exchange Act. The timing, volume, and nature of share repurchases pursuant to the Repurchase Program are at our management’s discretion and may be suspended or discontinued at any time. Shares repurchased under the Repurchase Program are retired immediately and are included in the category of authorized but unissued shares. Direct and incremental costs associated with the Repurchase Program are deferred and included as a component of the purchase price. The excess of the purchase price over the par value of the common shares is reflected in retained earnings.

33

The following table sets forth our share repurchases (in millions, except per share data):

	Three Months Ended March 31,
	2024		2023
Total number of shares repurchased	—		0.4
Amount repurchased	$	—	$	23.1
Average price per share	$	—	$	58.21

We did not make any share repurchases during the three months ended March 31, 2024. Share repurchases for the three months ended March 31, 2023 were made on the open market through a Rule 10b5-1 repurchase plan. During the three months ended March 31, 2023, we incurred de minimis costs directly attributable to the Repurchase Program.

As of March 31, 2024, we had approximately $389.1 million available for repurchases remaining under the Repurchase Program. See Note 7 in the Notes to Condensed Consolidated Financial Statements for additional information.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our market risk disclosures set forth in Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 have not changed materially during the three months ended March 31, 2024.

Item 4. Controls and Procedures

As of March 31, 2024, management, including the chief executive officer and interim chief financial officer, performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act). Based on that evaluation, management, including the chief executive officer and interim chief financial officer, concluded that as of March 31, 2024, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and to ensure that such information is accumulated and communicated to our management, including our chief executive officer and interim chief financial officer, as appropriate to allow timely decisions regarding required disclosure. We maintain a system of internal control over financial reporting that is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States.

There have been no material changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended March 31, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Summary of Significant Accounting Policies

Basis of Presentation

The Company prepared the condensed consolidated financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and the requirements of the Securities and Exchange Commission (“SEC”). As permitted under those rules, certain footnotes or other financial information have been condensed or omitted. Certain prior period amounts have been reclassified to conform to current period presentation.

The balance sheet as of March 31, 2023 has been presented for a better understanding of the impact of seasonal fluctuations on the Company’s financial condition. The three-month periods ended March 31, 2024 and 2023 each had 64 business days.

In management’s opinion, the unaudited condensed consolidated financial statements include all normal and recurring adjustments that are considered necessary for the fair presentation of the Company’s financial position and operating results. The results for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the twelve months ending December 31, 2024.

These unaudited condensed consolidated financial statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in the Company’s most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Recent Accounting Pronouncements — Not Yet Adopted

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements – Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative.” This standard affects a wide variety of Topics in the Codification. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. Early adoption is prohibited. The Company does not expect the adoption of this standard to have a material impact on the Company’s consolidated financial statements and related disclosures.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting - Improving Reportable Segment Disclosures (Topic 280).” The standard is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant expenses. The standard requires disclosures to include significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. The standard also requires all annual disclosures currently required by ASC Topic 280 to be included in interim periods. This standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures,” a final standard on improvements to income tax disclosures. The standard requires disaggregated information about a registrant's effective tax rate reconciliation as well as information on income taxes paid. This standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted and should be applied prospectively. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

Net Income (Loss) Per Common Share

3 Months Ended

Earnings Per Share [Abstract]

Net Income (Loss) Per Common Share

Net Income (Loss) Per Common Share

Basic net income (loss) per common share is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for common share equivalents or

the conversion of Preferred Stock (as defined below) when outstanding during the period. Common share equivalents consist of the incremental common shares issuable upon the exercise of stock options and vesting of restricted stock unit (“RSU”) awards. Diluted net income (loss) per common share is calculated by dividing net income (loss) attributable to common stockholders by the fully diluted weighted-average number of common shares outstanding during the period.

In connection with the acquisition of Allied Building Products Corp. on January 2, 2018, the Company completed the sale of 400,000 shares of Series A Cumulative Convertible Participating Preferred Stock, par value $0.01 per share (the “Preferred Stock”), with an aggregate liquidation preference of $400.0 million, at a purchase price of $1,000 per share, to CD&R Boulder Holdings, L.P. (“CD&R Holdings”).

On July 31, 2023 (the “Repurchase Date”), the Company repurchased (the “Repurchase”) all 400,000 issued and outstanding shares of the Preferred Stock held by CD&R Holdings (the shares of Preferred Stock held by CD&R Holdings, the “Shares”) pursuant to a letter agreement dated July 6, 2023 (the “Repurchase Letter Agreement”) in cash for $805.4 million, including $0.9 million of accrued but unpaid dividends as of such date (the “Repurchase Price”). In connection with the Repurchase, CD&R Holdings agreed that for as long as Philip Knisely or Nathan Sleeper remained a member of the Company’s Board and for a period of six months thereafter, the customary voting, standstill, and transfer restrictions set forth in the original Investment Agreement with respect to the Preferred Stock will continue to apply to CD&R Holdings and its related fund in accordance with their terms. Following the closing of the Repurchase, Mr. Sleeper resigned from the Company’s Board and Mr. Knisely remained a member of the Company’s Board until his resignation on January 23, 2024.

The aggregate Repurchase Price and related transaction fees and expenses were financed by a combination of proceeds from the 2030 Senior Notes, which are further described in Note 11, as well as the 2026 ABL and cash on hand.

On and after the Repurchase Date, all dividends and distributions ceased to accrue on the Shares, the repurchased Shares are no longer deemed outstanding, and all rights of CD&R Holdings with respect to the repurchased Shares terminated.

Before the Repurchase occurred, the Preferred Stock was convertible perpetual participating preferred stock of the Company, and conversion of the Preferred Stock into $0.01 par value shares of the Company’s common stock would have been at a conversion price of $41.26 per share (or 9,694,619 shares of common stock). The Preferred Stock accumulated dividends at a rate of 6.0% per annum (payable quarterly in cash or in-kind, subject to certain conditions). The Preferred Stock was not mandatorily redeemable; therefore, it was classified as mezzanine equity in the Company’s condensed consolidated balance sheets. Holders of Preferred Stock would have participated in dividends on an as-converted basis if declared on common shares. As a result, Preferred Stock was classified as a participating security and thereby required the allocation of income that would have otherwise been available to common stockholders when calculating net income (loss) per common share.

For periods in which Preferred Stock is outstanding, diluted net income (loss) per common share is calculated by utilizing the most dilutive result of the if-converted and two-class methods. In both methods, net income (loss) attributable to common stockholders and the weighted-average common shares outstanding are adjusted to account for the impact of the assumed issuance of potential common shares that are dilutive, subject to dilution sequencing rules.

The following table presents the components and calculations of basic and diluted net income (loss) per common share (in millions, except per share amounts; certain amounts may not recalculate due to rounding):

These shares were not included in the computation of diluted net income (loss) per common share because the effect was either anti-dilutive or the requisite performance conditions were not met (in millions):

Stock-based Compensation

Share-Based Payment Arrangement [Abstract]

Stock-based Compensation

Stock-based Compensation

On December 23, 2019, the Board of Directors of the Company (the “Board”) approved the Beacon Roofing Supply, Inc. Second Amended and Restated 2014 Stock Plan (the “2014 Plan”). On February 11, 2020, the stockholders of the Company approved an additional 4,850,000 shares to be reserved for issuance under the 2014 Plan. The 2014 Plan, which was originally approved by the stockholders on February 12, 2014, provides for discretionary awards of stock options, stock awards, restricted stock units, and stock appreciation rights to selected employees and non-employee directors. The 2014 Plan mandates that all shares underlying lapsed, forfeited, expired, terminated, cancelled and withheld awards, including those from the predecessor plan, be returned to the 2014 Plan and made available for issuance. As of March 31, 2024, there were 2,717,332 shares of common stock available for issuance pursuant to the 2014 Plan. The 2014 Plan is the only plan maintained by the Company pursuant to which equity awards are granted.

All unvested employee equity awards contain a “double trigger” change in control mechanism to the extent such employee equity award is continued or assumed after a change in control. If an award is not continued or assumed by a public company in an equitable manner, such award shall become vested immediately prior to a change in control (in the case of a restricted stock unit award with performance conditions at the then-calculable payout percentage for any completed annual performance periods and at 100% for any annual performance periods not yet calculable, and in the case of a restricted stock unit award with market conditions at 100% of the award then earned but not then vested). If an award is so continued or assumed, vesting will continue in accordance with the terms of the award, unless there is a qualifying termination (without cause or for good reason) within one-year following the change in control, in which event the award shall immediately become vested (in the case of a restricted stock unit award with performance conditions at the then-calculable payout percentage for any completed annual performance periods and at 100% for any annual performance periods not yet calculable, and in the case of a restricted stock unit award with market conditions at 100% of the award then earned but not then vested).

Stock Options

Non-qualified stock options generally expire 10 years after the grant date and, except under certain conditions, the options are subject to continued employment and vest in three annual installments over the three-year period following the grant date.

The fair values of the options granted for the periods presented were estimated on the dates of grants using the Black-Scholes option-pricing model with the following weighted-average assumptions:

	Three Months Ended March 31,
	2024		2023
Risk-free interest rate	4.12	%	4.26	%
Expected volatility	48.05	%	49.92	%
Expected life (in years)	5.08		5.12
Dividend yield	—		—

The following table summarizes all stock option activity for the three months ended March 31, 2024 (in millions, except per share amounts and time periods):

	Options Outstanding	Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value1
Balance as of December 31, 2023	1.1	$	41.38	5.8	$	51.3

1.Aggregate intrinsic value represents the difference between the closing fair value of the underlying common stock and the exercise price of outstanding, in-the-money options on the date of measurement.

During the three months ended March 31, 2024 and 2023, the Company recorded stock-based compensation expense related to stock options of $1.0 million and $0.9 million, respectively. During the three months ended March 31, 2024 and 2023, the Company recognized a tax benefit related to stock-based compensation expense related to stock options of $1.3 million and $0.4 million, respectively.

As of March 31, 2024, there was $6.7 million of unrecognized compensation expense related to unvested stock options, which is expected to be recognized over a weighted-average period of 2.1 years. The following table summarizes additional information on stock options (in millions, except per share amounts):

	Three Months Ended March 31,
	2024		2023
Weighted-average fair value per share of stock options granted	$	40.20	$	31.86
Total grant date fair value of stock options vested	$	2.7	$	1.8
Total intrinsic value of stock options exercised	$	6.4	$	3.3

Restricted Stock Units

Time-based RSU awards granted to employees are subject to continued employment and generally vest on the third anniversary of the grant date. The Company also grants certain RSU awards to management that additionally may contain market or performance conditions. Market conditions are incorporated into the grant date fair value of the management awards with market conditions using a Monte Carlo valuation model. Compensation expense for management awards with market conditions is recognized over the service period and is not reversed if the market condition is not met. For awards with performance conditions, the actual number of awards that will vest can range from 0% to 200% of the original grant amount, depending upon actual Company performance below or above

the established performance metric targets. At each reporting date, the Company estimates performance in relation to the defined targets when determining the projected number of management awards with performance conditions that are expected to vest and calculating the related stock-based compensation expense. Management awards with performance conditions are amortized over the service period if, and to the extent that, it is determined that achievement of the performance condition is probable. If awards with market, performance and/or service conditions are forfeited due to failure to achieve performance conditions or failure to satisfy service conditions, any previously recognized expense for such awards is reversed.

RSUs granted to non-employee directors are subject to continued service and vest on the first anniversary of the grant date (except under certain conditions). Generally, the common shares underlying the RSUs are not eligible for distribution until the non-employee director’s service on the Board has terminated, and for non-employee director RSU grants made prior to fiscal year 2014, the share distribution date is six months after the director’s termination of service on the Board. Any non-employee directors who have Beacon equity holdings (defined as common stock and outstanding vested equity awards) with a total fair value that is greater than or equal to five times the annual Board cash retainer may elect to have any future RSU grants settle simultaneously with vesting.

The following table summarizes all RSU activity for the three months ended March 31, 2024 (in millions, except grant date fair value amounts):

	RSUs Outstanding	Weighted-Average Grant Date Fair Value
Balance as of December 31, 2023	1.2	$	53.14

Vested and expected to vest after March 31, 20241	1.2	$	60.23

1.As of March 31, 2024, outstanding awards with performance conditions were expected to vest at less than 100% of their original grant amount.

During the three months ended March 31, 2024 and 2023, the Company recorded stock-based compensation expense related to RSUs of $5.8 million and $5.1 million, respectively. During the three months ended March 31, 2024 and 2023, the Company recognized a tax benefit related to stock-based compensation expense related to RSUs of $1.3 million and $0.1 million, respectively.

As of March 31, 2024, there was $46.0 million of unrecognized compensation expense related to unvested RSUs (including unrecognized expense for RSUs with performance conditions at their estimated value as of March 31, 2024), which is expected to be recognized over a weighted-average period of 2.3 years.

The following table summarizes additional information regarding RSUs (in millions, except per share amounts):

Employee Stock Purchase Plan

On March 20, 2023, the Board adopted the Company’s 2023 Employee Stock Purchase Plan (the “ESPP”), subject to stockholder approval, which was subsequently obtained on May 17, 2023 in conjunction with the 2023 Annual Meeting of Stockholders. The ESPP allows eligible employees to acquire shares of the Company’s common stock through payroll deductions over six-month offering periods. The purchase price per share is equal to 85% of the lesser of (1) the fair market value of a share of the Company’s common stock on the offering date, defined as the first trading day of the offering period, or (2) the fair market value of a share of the Company’s common stock on the purchase date, defined as the last trading day of the offering period; provided that the purchase price is not less than the $0.01 par value per share of the common stock. Participant purchases are limited to a maximum of $12,500 worth of stock per offering period (or $25,000 per calendar year). The Company is authorized to grant up to 1,000,000 shares of its common stock under the ESPP.

During the three months ended March 31, 2024, employees purchased approximately 58.0 thousand shares at a per share price of $70.86. As of March 31, 2024, there were approximately 942.0 thousand shares of common stock available for issuance pursuant to

the Company’s ESPP. During the three months ended March 31, 2024, the Company recorded stock-based compensation expense related to the ESPP of $0.6 million.

Share Repurchase Program

Share Repurchase Program

On February 24, 2022, the Company announced a new share repurchase program (the “Repurchase Program”), pursuant to which the Company may purchase up to $500.0 million of its common stock. On February 23, 2023, the Company announced that its Board authorized and approved an increase of the Repurchase Program by approximately $387.9 million, permitting future share repurchases of $500.0 million after considering actual share repurchases as of such re-authorization date.

Share repurchases under the Repurchase Program may be made from time to time through various means, including open market purchases (including block trades), privately negotiated transactions, accelerated share repurchase transactions (“ASR”) or through a series of forward purchase agreements, option contracts or similar agreements and contracts (including Rule 10b5-1 plans) adopted by the Company, in each case in accordance with the rules and regulations of the SEC, including, if applicable, Rule 10b-18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The timing, volume, and nature of share repurchases pursuant to the Repurchase Program are at the discretion of management and may be suspended or discontinued at any time. Shares repurchased under the Repurchase Program are retired immediately and are included in the category of authorized but unissued shares. Direct and incremental costs associated with the Repurchase Program are deferred and included as a component of the purchase price. The excess of the purchase price over the par value of the common shares is reflected in retained earnings.

The following table sets forth the Company’s share repurchases (in millions, except per share data):

The Company did not make any share repurchases during the three months ended March 31, 2024. Share repurchases for the three months ended March 31, 2023 were made on the open market through a Rule 10b5-1 repurchase plan. During the three months ended March 31, 2023, the Company incurred de minimis costs directly attributable to the Repurchase Program.

As of March 31, 2024, the Company had approximately $389.1 million available for repurchases remaining under the Repurchase Program.

Debt Refinancing

In May 2021, the Company entered into various financing arrangements to refinance certain debt instruments to take advantage of lower market interest rates for the Company’s fixed rate indebtedness and to extend maturities (the “2021 Debt Refinancing”). The transactions included a new $350.0 million issuance of senior notes (the “2029 Senior Notes”). In addition, the Company entered into a second amended and restated credit agreement for its $1.30 billion asset-based revolving line of credit (the “2026 ABL”), and an amended and restated term loan credit agreement for a term loan of $1.00 billion (the “2028 Term Loan”), which together are defined as the “Senior Secured Credit Facilities.”

On May 19, 2021, the Company used the net proceeds from the 2029 Senior Notes offering, together with cash on hand and borrowings under the Senior Secured Credit Facilities, to redeem all $1.30 billion aggregate principal amount outstanding of the Company’s 4.875% Senior Notes due 2025 at a redemption price of 102.438%, to refinance all outstanding borrowings under the Company’s previous term loan, and to pay all related accrued interest, fees and expenses.

In March 2024, the Company entered into a financing arrangement to refinance the 2028 Term Loan resulting in an increase in the outstanding principal balance from $975.0 million to $1.275 billion at March 31, 2024. Refer to the discussion below for additional information regarding the refinancing.

2029 Senior Notes

On May 10, 2021, the Company and certain subsidiaries of the Company as guarantors completed a private offering of $350.0 million aggregate principal amount of 4.125% senior unsecured notes due 2029 at an issue price equal to par. The 2029 Senior Notes mature on May 15, 2029 and bear interest at a rate of 4.125% per annum, payable on May 15 and November 15 of each year, which commenced on November 15, 2021. The 2029 Senior Notes are fully and unconditionally guaranteed, on a joint and several basis, by certain of the Company’s active United States subsidiaries.

The 2029 Senior Notes and related subsidiary guarantees were offered and sold in a private transaction exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), to qualified institutional buyers in accordance with Rule 144A under the Securities Act and to non-U.S. persons outside of the United States pursuant to Regulation S under the Securities Act. The 2029 Senior Notes and related subsidiary guarantees have not been, and will not be, registered under the Securities Act or the securities laws of any state or other jurisdiction, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and other applicable securities laws.

The Company capitalized debt issuance costs of $4.0 million related to the 2029 Senior Notes, which are being amortized over the term of the financing arrangements.

As of March 31, 2024, the outstanding balance on the 2029 Senior Notes, net of $2.6 million of unamortized debt issuance costs, was $347.4 million.

2026 ABL

On May 19, 2021, the Company entered into a $1.30 billion senior secured asset-based revolving credit facility with Wells Fargo Bank, N.A. and a syndicate of other lenders. The 2026 ABL provides for revolving loan commitments in both the United States in an amount up to $1.25 billion (“2026 U.S. Revolver”) and Canada in an amount up to $50.0 million (“2026 Canada Revolver”) (as such amounts may be reallocated pursuant to the terms of the 2026 ABL). The 2026 ABL has a maturity date of May 19, 2026. The 2026 ABL has various borrowing tranches with an interest rate based, at the Company’s option, on a base rate, plus an applicable margin, or a reserve adjusted LIBOR rate, plus an applicable margin. The applicable margin for borrowings is based on the Company’s quarterly average excess availability as determined by reference to a borrowing base and ranges from 0.25% to 0.75% per annum in the case of base rate borrowings and 1.25% to 1.75% per annum in the case of LIBOR borrowings. The unused commitment fees on the 2026 ABL are 0.20% per annum.

On June 6, 2023, the Company entered into Amendment No. 2 to the 2026 ABL (the “2026 ABL Amendment No. 2”) with Wells Fargo Bank, N.A., as administrative agent and collateral agent, and the lenders party thereto. The 2026 ABL Amendment No. 2, among other things, (i) replaced the LIBOR interest rate index and its related borrowing mechanics under the 2026 ABL with a SOFR interest rate index and its related borrowing mechanics, and (ii) updated certain other provisions of the 2026 ABL to reflect the transition from LIBOR to SOFR. Except as amended by the 2026 ABL Amendment No. 2, the remaining terms of the 2026 ABL remain in full force and effect.

The 2026 ABL contains a springing financial covenant that requires a minimum 1.00:1.00 Fixed Charge Coverage Ratio (consolidated EBITDA less capital expenditures to fixed charges, each as defined in the 2026 ABL credit agreement) as of the end of each fiscal quarter (in each case, calculated on a trailing four fiscal quarter basis). The covenant would become operative if the Company failed to maintain a specified minimum amount of availability to borrow under the 2026 ABL, which was not applicable to the Company as of March 31, 2024.

In addition, the Senior Secured Credit Facilities and the 2029 Senior Notes (as well as the 2030 Senior Notes and the 2026 Senior Notes, each as defined below) are subject to negative covenants that, among other things and subject to certain exceptions, limit the Company’s ability and the ability of its restricted subsidiaries to: (i) incur indebtedness (including guarantee obligations); (ii) incur liens; (iii) engage in mergers or other fundamental changes; (iv) dispose of certain property or assets; (v) make certain payments, dividends or other distributions; (vi) make certain acquisitions, investments, loans and advances; (vii) prepay certain indebtedness; (viii) change the nature of their business; (ix) engage in certain transactions with affiliates; (x) engage in sale-leaseback transactions; and (xi) enter into certain other restrictive agreements. The 2026 ABL is secured by a first priority lien over substantially all of the Company’s and each guarantor’s accounts and other receivables, chattel paper, deposit accounts (excluding any such account containing identifiable proceeds of Term Priority Collateral (as defined below)), inventory, and, to the extent related to the foregoing and other ABL Priority Collateral, general intangibles (excluding equity interests in any subsidiary of the Company and all intellectual property), instruments, investment property (but not equity interests in any subsidiary of the Company), commercial tort claims, letters of credit, supporting obligations and letter of credit rights, together with all books, records and documents related to, and all proceeds and products of, the foregoing, subject to certain customary exceptions (the “ABL Priority Collateral”), and a second priority lien over substantially all of the Company’s and each guarantor’s other assets, including all of the equity interests of any subsidiary held by the Company or any guarantor, subject to certain customary exceptions (the “Term Priority Collateral”). Beacon Sales Acquisition, Inc., a Delaware corporation and subsidiary of the Company, is a U.S. Borrower under the 2026 ABL and Beacon Roofing Supply Canada Company, an unlimited liability company organized under the laws of Nova Scotia and subsidiary of the Company, is a Canadian borrower under the 2026 ABL. The 2026 ABL is fully and unconditionally guaranteed, on a joint and several basis, by the Company’s active U.S. subsidiaries.

The Company capitalized debt issuance costs of $8.3 million related to the 2026 ABL, which are being amortized over the term of the financing arrangements.

As of March 31, 2024, the outstanding balance on the 2026 ABL, net of $3.5 million of unamortized debt issuance costs, was $111.5 million. The Company also had outstanding standby letters of credit related to the 2026 U.S. Revolver in the amount of $15.8 million as of March 31, 2024.

2028 Term Loan

On May 19, 2021, the Company entered into a $1.00 billion senior secured term loan B facility with Citibank, N.A. and a syndicate of other lenders. The 2028 Term Loan requires quarterly principal payments in the amount of $2.5 million, with the remaining outstanding principal to be paid on its May 19, 2028 maturity date. The interest rate is based, at the Company’s option, on a base rate, plus an applicable margin, or a reserve adjusted LIBOR rate, plus an applicable margin. The applicable margin for the 2028 Term Loan ranges, depending on the Company’s consolidated total leverage ratio (consolidated total indebtedness to consolidated EBITDA, each as defined in the 2028 Term Loan credit agreement), from 1.25% to 1.50% per annum in the case of base rate borrowings and 2.25% to 2.50% per annum in the case of LIBOR borrowings.

On July 3, 2023, the Company entered into Amendment No. 2 to the 2028 Term Loan (the “2028 Term Loan Amendment No. 2”) with Citibank, N.A., as administrative agent and collateral agent, and the lenders party thereto. The 2028 Term Loan Amendment No. 2, among other things, (i) replaced the LIBOR interest rate index and its related borrowing mechanics under the 2028 Term Loan with a SOFR interest rate index and its related borrowing mechanics, and (ii) updated certain other provisions of the 2028 Term Loan to reflect the transition from LIBOR to SOFR. Except as amended by the 2028 Term Loan Amendment No. 2, the remaining terms of the 2028 Term Loan remain in full force and effect.

On March 28, 2024. the Company entered into Amendment No. 3 to the 2028 Term Loan (the “2028 Term Loan Amendment No. 3”) with Citibank, N.A., as administrative agent and collateral agent, and the lenders party thereto, to refinance the 2028 Term Loan (the “2028 Term Loan Refinancing”). The 2028 Term Loan Amendment No. 3, among other things, (i) increases the aggregate outstanding amount of outstanding term loans to $1.275 billion, (ii) reduces the interest rate to a rate per annum equal to Term SOFR with a 0.00% floor, plus a margin equal to 2.00%, and (iii) increases the required quarterly principal payments from $2.5 million to $3.2 million starting March 31, 2024. Except as amended by the 2028 Term Loan Amendment No. 3, the remaining terms of the 2028 Term Loan remain in full force and effect.

The 2028 Term Loan Refinancing had certain lenders who also participated in previous financing arrangements entered into by the Company; therefore, a portion of the transaction was accounted for as either a debt extinguishment or debt modification. The Company recognized a loss on debt extinguishment totaling $2.4 million during the three months ended March 31, 2024. In addition, unamortized historical debt issuance costs of $9.7 million and new debt issuance costs of $0.1 million related to the 2028 Term Loan are being amortized over the term of the financing arrangement.

The 2028 Term Loan is secured by a shared first-priority lien on the Term Priority Collateral and a shared second-priority lien on the ABL Priority Collateral. Certain excluded assets will not be included in the Term Priority Collateral and the ABL Priority Collateral. The 2028 Term Loan is fully and unconditionally guaranteed, on a joint and several basis, by certain of the Company’s active U.S. subsidiaries.

On March 16, 2023, the Company novated and amended its interest rate swap agreement related to the 2028 Term Loan. For additional information, see Note 17.

As of March 31, 2024, the outstanding balance on the 2028 Term Loan, net of $9.8 million of unamortized debt issuance costs, was $1.27 billion.

2030 Senior Notes

On July 31, 2023, the Company, and certain subsidiaries of the Company as guarantors, completed a private offering of $600.0 million aggregate principal amount of 6.500% Senior Secured Notes due 2030 (the “2030 Senior Notes”) at an issue price equal to par. The 2030 Senior Notes mature on August 1, 2030 and bear interest at a rate of 6.500% per annum, payable on February 1 and August 1 of each year, commencing on February 1, 2024. The 2030 Senior Notes and related subsidiary guarantees are secured by a shared first-priority lien on the Term Priority Collateral and a shared second-priority lien on the ABL Priority Collateral. Certain excluded assets will not be included in the Term Priority Collateral and the ABL Priority Collateral. The 2030 Senior Notes are fully and unconditionally guaranteed, on a joint and several basis, by certain of the Company’s active U.S. subsidiaries.

The 2030 Senior Notes and related subsidiary guarantees were offered and sold in a private transaction exempt from the registration requirements of the Securities Act, to qualified institutional buyers in accordance with Rule 144A under the Securities Act and to non-U.S. persons outside of the United States pursuant to Regulation S under the Securities Act. The 2030 Senior Notes and related subsidiary guarantees have not been, and will not be, registered under the Securities Act or the securities laws of any state or other jurisdiction, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and other applicable securities laws.

On July 31, 2023 the Company used net proceeds from the offering, together with cash on hand and available borrowings under the 2026 ABL to complete the Repurchase of the Preferred Stock.

The Company capitalized debt issuance costs of $8.1 million related to the 2030 Senior Notes, which are being amortized over the term of the financing arrangement.

As of March 31, 2024, the outstanding balance on the 2030 Senior Notes, net of $7.4 million of unamortized debt issuance costs, was $592.6 million.

The 2026 Senior Notes mature on November 15, 2026 and bear interest at a rate of 4.50% per annum, payable on May 15 and November 15 of each year, commencing on May 15, 2020. The 2026 Senior Notes and related subsidiary guarantees are secured by a shared first-priority lien on the Term Priority Collateral and a shared second-priority lien on the ABL Priority Collateral. Certain excluded assets will not be included in the Term Priority Collateral and the ABL Priority Collateral. The 2026 Senior Notes are fully and unconditionally guaranteed, on a joint and several basis, by certain of the Company’s active U.S. subsidiaries.

The 2026 Senior Notes and related subsidiary guarantees were offered and sold in a private transaction exempt from the registration requirements of the Securities Act, to qualified institutional buyers in accordance with Rule 144A under the Securities Act and to non-U.S. persons outside of the United States pursuant to Regulation S under the Securities Act.

On October 28, 2019, the Company used the net proceeds from the offering, together with cash on hand and available borrowings under the Company’s previous asset-based revolving credit facility, to redeem all $300.0 million aggregate principal amount outstanding of the Company’s 6.375% Senior Notes due 2023.

The Company capitalized debt issuance costs of $4.7 million related to the 2026 Senior Notes, which are being amortized over the term of the financing arrangements.

Commitments and Contingencies

The Company is subject to loss contingencies pursuant to various federal, state, and local environmental laws and regulations; however, the Company is not aware of any reasonably possible losses that would have a material impact on its results of operations, financial position, or liquidity. Potential environmental loss contingencies include possible obligations to remove or mitigate the effects on the environment of the placement, storage, disposal, or release of certain chemical or other substances by the Company or by other parties. Historically, environmental liabilities have not had a material impact on the Company’s results of operations, financial position, or liquidity.

The Company is subject to litigation and governmental investigations from time to time in the ordinary course of business; however, the Company does not expect the results, if any, to have a material adverse impact on its results of operations, financial position, or liquidity. The Company accrues a liability for legal claims when payments associated with the claims become probable and the costs can be reasonably estimated. The Company also considers whether an insurance recovery receivable is applicable and appropriate based on the specific legal claim. The actual costs of resolving legal claims and governmental investigations may be substantially higher or lower than the amounts accrued for those activities.

In December 2018, a Company vehicle was involved in an accident that resulted in a fatality. The estate of the decedent and two bystanders filed a lawsuit in October 2019 in the Fourth Judicial District Court for Utah County, Provo Division, against the driver and the Company. Trial was held in late August 2022; the jury determined that the truck driver was not liable for the accident. The plaintiffs filed post-trial motions seeking a judgment as a matter of law or for a new trial. In April 2023, the trial court ruled on the plaintiffs’ motions, granting plaintiffs judgment against the driver and ordering that the second phase of the trial proceed. On June 29, 2023, the Utah appeals court granted the Company’s petition for an interlocutory appeal. There is not a probable loss with respect to this matter and any potential loss in regard to this matter is not reasonably estimable. Accordingly, the Company has not accrued any amounts related to this matter within its financial statements as of March 31, 2024.

Fair Value Measurement

Fair Value Measurement

As of March 31, 2024, the carrying amount of cash and cash equivalents, accounts receivable, prepaid and other current assets, accounts payable, and accrued expenses approximated fair value because of the short-term nature of these instruments. The Company measures its cash equivalents at amortized cost, which approximates fair value based upon quoted market prices (Level 1).

As of March 31, 2024, based upon recent trading prices (Level 2), the fair values of the Company’s $300.0 million 2026 Senior Notes, $350.0 million 2029 Senior Notes, and $600.0 million 2030 Senior Notes were $291.8 million, $318.1 million, and $608.3 million, respectively.

As of March 31, 2024, the fair value of the Company’s term loan and revolving lines of credit approximated the amount outstanding. The Company estimates the fair value of its term loan and revolving lines of credit by discounting the future cash flows of each instrument using estimated market rates of debt instruments with similar maturities and credit profiles (Level 3).

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Financial Derivatives

Financial Derivatives

The Company uses interest rate derivative instruments to manage the risk related to fluctuating cash flows from interest rate changes by converting a portion of its variable-rate borrowings into fixed-rate borrowings.

On September 11, 2019, the Company entered into two interest rate swap agreements to manage the interest rate risk associated with the variable rate on the Company’s previous term loan. Each swap agreement has a notional amount of $250.0 million. As part of the 2021 Debt Refinancing, Beacon refinanced its previous term loan, resulting in the issuance of the 2028 Term Loan; the two interest rate swaps were designed and executed such that they continue to hedge against a total notional amount of $500.0 million related to the refinanced 2028 Term Loan. One agreement (the “5-year swap”) was scheduled to expire on August 30, 2024 and swaps the thirty-day LIBOR with a fixed-rate of 1.49%. The second agreement (the “3-year swap”) expired on August 30, 2022 and swapped the thirty-day LIBOR with a fixed-rate of 1.50%. At the inception of the swap agreements, the Company determined that both swaps qualified for cash flow hedge accounting under ASC 815. Therefore, changes in the fair value of the swaps, net of taxes, were recognized in other comprehensive income each period, then reclassified into the condensed consolidated statements of operations as a component of interest expense, financing costs and other, net in the period in which the hedged transaction affects earnings.

On March 16, 2023, the Company novated its 5-year swap agreement to another counterparty and, in connection with such novation, amended the interest rate swap agreement. The amendment changed the index rate from LIBOR to SOFR, increased the total notional

amount of the interest rate swap to $500.0 million, and extended the termination date to March 31, 2027 (the “2027 interest rate swap”). Specifically, the fixed rate of 1.49% indexed to LIBOR was modified to 3.00% indexed to SOFR. The Company used a strategy commonly referred to as “blend and extend” which allows the asset position of the novated 5-year swap agreement of approximately $9.9 million to be effectively blended into the new 2027 interest rate swap agreement. As a result of this transaction, on March 16, 2023, the 5-year swap agreement was de-designated and the unrealized gain of $9.9 million included within accumulated other comprehensive income was frozen and will be ratably reclassified as a reduction to interest expense, financing costs and other, net over the original term of the 5-year swap, or through August 30, 2024 as the hedged transactions affect earnings. Additionally, the 2027 interest rate swap had a fair value of $9.9 million at inception and will be ratably recorded to accumulated other comprehensive income and reclassified to interest expense, financing costs and other, net over the term of the 2027 interest rate swap, or through March 31, 2027 as the hedged transactions affect earnings. At the inception of the 2027 interest rate swap, the Company determined that the swap qualified for cash flow hedge accounting under ASC 815. Therefore, changes in the fair value of the swap, net of taxes, will be recognized in other comprehensive income each period, then reclassified into the condensed consolidated statements of operations as a component of interest expense, financing costs and other, net in the period in which the hedged transaction affects earnings. The 2027 interest rate swap is the only swap agreement outstanding as of March 31, 2024.

The effectiveness of the outstanding 2027 interest rate swap will be assessed qualitatively by the Company during the life of the hedge by (i) comparing the current terms of the hedge with the related hedged debt to assure they continue to coincide and (ii) through an evaluation of the ability of the counterparty to the hedge to honor its obligations under the hedge. The Company performed a qualitative analysis as of March 31, 2024 and concluded that the outstanding 2027 interest rate swap continues to meet the requirements under ASC 815 to qualify for cash flow hedge accounting. As of March 31, 2024, the fair value of the 2027 interest rate swap, net of tax, was $12.9 million in favor of the Company.

During the three months ended March 31, 2024, the Company reclassified gains of $0.8 million out of accumulated other comprehensive income (loss) and to interest expense, financing costs and other, net. Approximately $9.6 million of net gains included in accumulated other comprehensive income (loss) at March 31, 2024 is expected to be reclassified into earnings within the next 12 months as interest payments are made on the Company’s Term Loan and amortization of the frozen AOCI on the 5-year swap and inception date fair value of the 2027 interest rate swap occurs. The Company records any differences paid or received on its interest rate hedges to interest expense, financing costs and other, net within the condensed consolidated statements of operations.

The fair value of the interest rate swap is determined through the use of a pricing model, which utilizes verifiable inputs such as market interest rates that are observable at commonly quoted intervals (generally referred to as the “forward curve”) for the full terms of the hedge agreements. These values reflect a Level 2 measurement under the applicable fair value hierarchy. The following table summarizes the combined fair values, net of tax, of the interest rate derivative instrument (in millions):

		Net Assets (Liabilities) as of
		March 31,		December 31,		March 31,

Basis of Presentation

Basis of Presentation

The Company prepared the condensed consolidated financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and the requirements of the Securities and Exchange Commission (“SEC”). As permitted under those rules, certain footnotes or other financial information have been condensed or omitted. Certain prior period amounts have been reclassified to conform to current period presentation.

The balance sheet as of March 31, 2023 has been presented for a better understanding of the impact of seasonal fluctuations on the Company’s financial condition. The three-month periods ended March 31, 2024 and 2023 each had 64 business days.

In management’s opinion, the unaudited condensed consolidated financial statements include all normal and recurring adjustments that are considered necessary for the fair presentation of the Company’s financial position and operating results. The results for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the twelve months ending December 31, 2024.

These unaudited condensed consolidated financial statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in the Company’s most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements – Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative.” This standard affects a wide variety of Topics in the Codification. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. Early adoption is prohibited. The Company does not expect the adoption of this standard to have a material impact on the Company’s consolidated financial statements and related disclosures.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting - Improving Reportable Segment Disclosures (Topic 280).” The standard is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant expenses. The standard requires disclosures to include significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. The standard also requires all annual disclosures currently required by ASC Topic 280 to be included in interim periods. This standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures,” a final standard on improvements to income tax disclosures. The standard requires disaggregated information about a registrant's effective tax rate reconciliation as well as information on income taxes paid. This standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted and should be applied prospectively. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.
