Accounting Policies [Abstract]
Business Overview and Significant Accounting Policies	Business Overview and Significant Accounting Policies Unless we state otherwise or the context otherwise requires, references to "Masonite," "we," "our," "us" and the "Company" in these notes to the condensed consolidated financial statements refer to Masonite International Corporation and its subsidiaries. Description of Business Masonite International Corporation is a leading global designer, manufacturer, marketer and distributor of interior and exterior doors, door system components and door systems for the new construction and repair, renovation and remodeling sectors of the residential and non-residential building construction markets. Masonite operates 63 manufacturing locations in seven countries and sells doors to customers throughout the world with our largest markets being the United States, Canada and the United Kingdom. Basis of Presentation We prepare these unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") and applicable rules and regulations of the U.S. Securities and Exchange Commission ("SEC") regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, all adjustments consisting of normal and recurring entries considered necessary for a fair presentation of the results for the interim periods presented have been included. All significant intercompany balances and transactions have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts in the financial statements and accompanying notes. These estimates are based on information available as of the date of the unaudited condensed consolidated financial statements; therefore, actual results could differ from those estimates. Interim results are not necessarily indicative of the results for a full year. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the fiscal year ended January 1, 2023, as filed with the SEC (the "Annual Report"). Our fiscal year is the 52- or 53-week period ending on the Sunday closest to December 31. In a 52-week year, each fiscal quarter consists of 13 weeks. For ease of disclosure, the 13-week periods are referred to as three-month periods and the 52- or 53-week periods are referred to as a year. Changes in Accounting Standards and Policies There have been no changes in the significant accounting policies from those that were disclosed in the fiscal year 2022 audited consolidated financial statements, other than as noted below. Adoption of Recent Accounting Pronouncements In December 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2021-10, "Government Assistance," which requires annual disclosures that increase the transparency of transactions involving government grants, including (1) the types of transactions, (2) the accounting for those transactions and (3) the effect of those transactions on an entity's financial statements. The guidance is effective for annual periods beginning after December 15, 2021, with early adoption permitted. We adopted the new guidance as of January 3, 2022, the beginning of fiscal year 2022, and the adoption did not have a material impact on our financial statements. In October 2021, the FASB issued ASU 2021-08, "Accounting for Contract Assets and Contract Liabilities from Contracts with Customers," which clarifies that an acquirer of a business should recognize and measure contract assets and contract liabilities in a business combination in accordance with ASU 2014-09, "Revenue from Contracts with Customers" as if the entity had originated the contracts. We adopted the new guidance as of January 1, 2023, the beginning of fiscal year 2023, and the adoption did not have a material impact on our financial statements.

Business Combination and Asset Acquisition [Abstract]
Acquisitions and Divestitures	Acquisitions and Divestitures Acquisitions On January 3, 2023, we completed the acquisition of 100% of the outstanding equity of EPI Holdings, Inc. ("Endura"), for total consideration of approximately$403.3 million, including an $18.0 million holdback which is payable 24 months after the acquisition date and was recorded in the consolidated balance sheets as a component of other liabilities. Endura is a leading innovator and manufacturer of high-performance door frames and door system components in the United States. Endura’s product offerings include engineered frames, self-adjusting sill systems, weather sealing, multi-point locks and installation accessories used by builders and contractors in residential new construction as well as repair and remodeling applications. The acquisition is intended to accelerate our Doors That Do More TM strategy and maximize our growth potential. The $182.9 million excess purchase price over the fair value of tangible and intangible assets acquired was allocated to goodwill. The goodwill principally represents anticipated synergies to be gained from the integration into our existing business and acquisition of the assembled workforce. This goodwill is not deductible for tax purposes and relates to the North American Residential segment. The Company has accounted for the acquisition as a business combination and allocated the preliminary estimated purchase price to the estimated fair values of assets acquired and liabilities assumed utilizing various valuation methods including replacement cost, market values and the income approach. The Company has not yet completed its evaluation and determination of certain assets acquired and liabilities assumed, primarily (i) the final valuation of intangible assets related to customers relationships, patents and trade names, and (ii) the final assessment and valuation of certain other assets acquired and liabilities assumed, including inventory, property, plant and equipment, leases, and deferred income taxes, which could also impact goodwill during the measurement period. The allocation of the purchase price to assets acquired and liabilities assumed is as follows: (In thousands) Initial Purchase Price Allocation Measurement Period Adjustments Preliminary Purchase Price Allocation Cash acquired $ 32,501 $ (100) $ 32,401 Accounts receivable, net 7,871 290 8,161 Inventories, net 44,183 35 44,218 Property, plant and equipment, net 54,373 10,576 64,949 Goodwill 189,938 (7,044) 182,894 Intangible assets 135,800 (7,400) 128,400 Accounts payable and accrued expenses (15,088) (190) (15,278) Deferred income taxes (44,345) (946) (45,291) Other assets and liabilities, net 2,868 (35) 2,833 Total purchase price $ 408,101 $ (4,814) $ 403,287 The fair values of intangible assets acquired are based on management's estimates and assumptions including the income approach, the cost approach and the market approach. The intangible assets acquired are not expected to have any residual value. The gross contractual value of acquired trade receivables was $8.3 million. Intangible assets acquired from the Endura acquisition consist of the following: Fair Value Expected Useful Life (Years) Customer relationships $ 108,600 10 Trademarks and trade names 6,600 10 Patents 13,200 12 Total intangible assets acquired $ 128,400 Endura's results of operations were included in the condensed consolidated statements of income and comprehensive income for the period subsequent to the acquisition date. For the three and nine months ended October 1, 2023, Endura had net sales of $59.7 million and $178.9 million, respectively. For the three and nine months ended October 1, 2023, Endura had $1.7 million in net income attributable to Masonite and $1.5 million in net loss attributable to Masonite, respectively. Pro Forma Information The following unaudited pro forma financial information represents the consolidated financial information as if the Endura acquisition had been included in our consolidated results beginning on January 2, 2022, the first day of the fiscal year prior to the respective acquisition date. The pro forma results have been calculated after adjusting the results of the acquired entities to remove intercompany transactions and to reflect the additional depreciation, amortization and interest expense that would have been charged assuming the fair value adjustments to property, plant and equipment and intangible assets and the additional debt incurred to fund the acquisition had been applied on the first day of the fiscal year prior to the respective acquisition date, together with the consequential tax effects. The pro forma results do not reflect any cost savings, operating synergies or revenue enhancements that the combined companies may achieve as a result of the acquisition; the costs to combine the companies' operations; or the costs necessary to achieve these costs savings, operating synergies and revenue enhancements. As a result, the pro forma information below does not purport to represent actual results had the acquisition been consummated on the date indicated and it is not necessarily indicative of future results of operations.

Receivables [Abstract]
Accounts Receivable	Accounts Receivable Our customers consist mainly of retailers, distributors and contractors. Our ten largest customers accounted for 59.4% and 62.3% of total accounts receivable as of October 1, 2023, and January 1, 2023, respectively. Our largest customer, The Home Depot, Inc., accounted for more than 10% of the consolidated gross accounts receivable balance as of October 1, 2023, and January 1, 2023. In addition, Lowe's Companies, Inc. accounted for more than 10% of the consolidated gross accounts receivable balance as of October 1, 2023. The allowance for doubtful accounts balance was $2.9 million and $2.5 million as of October 1, 2023, and January 1, 2023, respectively. We maintain an accounts receivable sales program with a third party (the "AR Sales Program"). Under the AR Sales Program, we can transfer ownership of eligible trade accounts receivable of certain customers. Receivables are sold outright to a third party who assumes the full risk of collection, without recourse to us in the event of a loss. Transfers of receivables under this AR Sales Program are accounted for as sales. Proceeds from the transfers reflect the face value of the accounts receivable less a discount. Receivables sold under the AR Sales Program are excluded from trade accounts receivable in the condensed consolidated balance sheets and are included in cash flows from operating activities in the condensed consolidated statements of cash flows. The discounts on the sales of trade accounts receivable sold, if any, under the AR Sales Program were not material for any of the periods presented and were recorded in selling, general and administration expenses within the condensed consolidated statements of income and comprehensive income. In most countries we pay and collect Value Added Tax ("VAT") when procuring goods and services within the normal course of business. VAT receivables are established in jurisdictions where VAT paid exceeds VAT collected and are recoverable through the filing of refund claims.

The 2030 Notes bear interest at 3.50% per annum, payable in cash semiannually in arrears on February 15 and August 15 of each year and are due February 15, 2030. The 2030 Notes were issued at par. Information concerning obligations under the 2030 Notes and the indenture governing them are described in detail in our Annual Report. As of October 1, 2023, we were in compliance with all covenants under the indenture governing the 2030 Notes. 5.375% Senior Notes due 2028 On July 25, 2019, we issued $500.0 million aggregate principal senior unsecured notes (the "2028 Notes"). The 2028 Notes bear interest at 5.375%, payable in cash semiannually in arrears on February 1 and August 1 of each year and are due February 1, 2028. The 2028 Notes were issued at par. Information concerning obligations under the 2028 Notes and the indenture governing them are described in detail in our Annual Report. As of October 1, 2023, we were in compliance with all covenants under the indenture governing the 2028 Notes. Term Loan Facility On December 13, 2022, we and certain of our subsidiaries entered into a new delayed-draw term loan credit agreement (the "Term Loan Credit Agreement") maturing on December 12, 2027 (the "Term Loan Maturity Date"). The Term Loan Credit Agreement provides for a senior secured five-year delayed-draw term loan facility of $250.0 million (the "Term Loan Facility"). Loans under the Term Loan Facility (the "Term Loans") will bear interest at a rate equal to, at our option, (1) the Adjusted Term SOFR Rate (as defined in the Term Loan Credit Agreement) plus an applicable margin of 2.25% or (2) an alternate base rate equal to the greatest of (i) the "Prime Rate" in the U.S. last quoted by The Wall Street Journal, (ii) 0.50% above the greater of the federal funds rate and the rate comprised of both overnight federal funds and overnight Eurodollar transactions denominated in U.S. dollars, (iii) 1.00% above the Adjusted Term SOFR Rate for a one month interest period and (iv) 1.00%, plus, in each case, an applicable margin of 1.25%, subject to, in each of cases (1) and (2), an agreed interest rate floor. The Term Loans are repayable in equal quarterly installments for an annual aggregate amortization payment equal to 15% of the aggregate principal amount of the Term Loans, with the balance of the principal being due on the Term Loan Maturity Date. Obligations under the Term Loan Credit Agreement are fully and unconditionally guaranteed, jointly and severally, by us and by certain of our directly or indirectly wholly owned subsidiaries organized in the U.S. and are secured by the equity in, and substantially all the assets of, such subsidiaries. The Term Loans were funded in an amount of $250.0 million and applied to finance a portion of the consideration payable in connection with the consummation of the Endura acquisition on January 3, 2023. We received net proceeds of $246.4 million after deducting $3.6 million of debt issuance costs. The debt issuance costs were capitalized as a reduction to the carrying value of debt and are being accreted to interest expense over the term of the Term Loan using the effective interest method. The Term Loan Credit Agreement contains various customary representations, warranties by us and covenants that are described in detail in our Annual Report. As of October 1, 2023, we were in compliance with all covenants under the indenture governing the Term Loan Credit Agreement. ABL Facility On January 31, 2019, we and certain of our subsidiaries entered into a $250.0 million asset-based revolving credit facility (the "ABL Facility") maturing on January 31, 2024, which replaced the previous facility. On October 28, 2022, we and certain of our subsidiaries entered into an amendment which, among other things, (i) increased the revolving credit commitments available thereunder by $100.0 million to an aggregate amount of $350.0 million and (ii) replaced the LIBOR-based interest rate applicable to borrowings thereunder in U.S. dollars with an interest rate based on the sum of (x) a "Term SOFR" rate published by the CME Group Benchmark Administration Limited (CBA) plus (y) 10 basis points ("Adjusted Term SOFR"). Additionally, on December 12, 2022, we entered into an amendment to the ABL Facility, which, among other things, extended the maturity of the ABL Facility from January 31, 2024 to December 12, 2027. The terms of the ABL Facility remained otherwise substantially unchanged and are described in detail in our Annual Report. On January 3, 2023, we borrowed $100.0 million under our ABL Facility in order to fund a portion of the cash consideration paid for the acquisition of Endura. During the first quarter of 2023, we repaid all amounts outstanding under the ABL Facility. The ABL Facility contains various customary representations, warranties by us and covenants that are described in detail in our Annual Report. As of October 1, 2023, we were in compliance with all covenants under the credit agreement governing the ABL Facility. We had availability of $276.0 million under our ABL Facility, and there were no amounts outstanding as of October 1, 2023.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We may become involved from time-to-time in litigation and regulatory compliance matters incidental to our business, including employment and wage and hour claims, antitrust, tax, product liability, environmental, health and safety, commercial disputes, intellectual property, contracts and other matters arising out of the normal conduct of our business. Since litigation is inherently unpredictable and unfavorable resolutions can occur, assessing contingencies is highly subjective and requires judgments about future events. We regularly review and accrue for contingencies related to litigation and regulatory compliance matters, if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Based on current information, in the opinion of management, the ultimate resolution of these matters, individually or in the aggregate, will not have a material adverse effect on our financial condition, results of operations or cash flows. Antitrust Class Action Proceedings - Canada On May 19, 2020, an intended class proceeding was commenced in the Province of Québec, Canada naming as defendants Masonite Corporation, Corporation Internationale Masonite, JELD-WEN, Inc., JELD-WEN Holding, Inc. and JELD-WEN of Canada, Ltd. The plaintiff alleges that the Masonite and JELD-WEN defendants engaged in anticompetitive conduct, including price-fixing involving interior molded doors. The intended class proceeding seeks damages, punitive damages, and other relief. On December 22, 2020, the parties filed a motion with the court seeking to stay the proceeding. On October 2, 2020, an intended class proceeding was commenced in the Federal Court of Canada naming as defendants Masonite International Corporation, Masonite Corporation, JELD-WEN, Inc., JELD-WEN Holding, Inc. and JELD-WEN of Canada, Ltd. The plaintiff alleges that the Masonite and JELD-WEN defendants engaged in anticompetitive conduct, including price-fixing involving interior molded doors. The intended class proceeding seeks damages, punitive damages, and other relief. The plaintiff served its certification record on March 31, 2021. On November 3, 2023, the Company entered into a preliminary settlement agreement with the plaintiff class that would result in the resolution of all the plaintiffs’ underlying claims and lawsuits in exchange for a payment by the Company of approximately $0.9 million. As a result, for the three and nine months ended October 1, 2023, we accrued approximately $0.9 million in selling, general and administrative expense in the condensed consolidated statement of income and comprehensive income in connection with this matter. The preliminary settlement agreement is subject to court approval. A settlement approval hearing date has not yet been set.

Share-Based Payment Arrangement [Abstract]
Share Based Compensation Plans	Share Based Compensation Plans Share based compensation expense was $4.3 million and $17.4 million for the three and nine months ended October 1, 2023, respectively, and $5.6 million and $16.3 million for the three and nine months ended October 2, 2022, respectively. As of October 1, 2023, the total remaining unrecognized compensation expense related to share based compensation amounted to $31.8 million, which will be amortized over the weighted average remaining requisite service period of 1.7 years. Equity Incentive Plans Our equity incentive plans under the 2021 Equity Plan and 2012 Plan are described in detail and defined in our Annual Report. The aggregate number of common shares that can be issued with respect to equity awards under the 2021 Equity Plan cannot exceed 880,000 shares; plus the number of shares reserved for the 2012 Plan that is in excess of the number of shares related to outstanding grants; plus the number of shares subject to existing grants under the 2012 Plan that may expire or be forfeited or cancelled. As of October 1, 2023, there were 766,368 shares of common stock available for future issuance under the 2021 Equity Plan. Deferred Compensation Plan We offer to certain of our employees and directors a Deferred Compensation Plan, which is further described and defined in our Annual Report. As of October 1, 2023, the liability and asset relating to deferred compensation had a fair value of $8.0 million and $7.3 million, respectively. As of October 1, 2023, participation in the deferred compensation plan is limited and no restricted stock awards have been deferred into the deferred compensation plan. All plan investments are categorized as having Level 1 valuation inputs as established by the FASB’s Fair Value Framework. Stock Appreciation Rights We have granted Stock Appreciation Rights ("SARs") to certain employees, which entitle the recipient to the appreciation in value of granted common shares over the exercise price over a period of time, each as specified in the applicable award agreement. The exercise price of any SAR granted may not be less than the fair market value of our common shares on the date of grant. The compensation expense for the SARs is measured based on the fair value of the SARs at the date of grant and is recognized over the requisite service period. The SARs vest over a maximum of three years, have a life of ten years and settle in common shares. It is assumed that all time-based SARs will vest. We recognize forfeitures of SARs in the period in which they occur. The total fair value of SARs vested was $0.7 million during the nine months ended October 1, 2023.

Expected volatility is based upon the historical volatility of our common shares amongst other considerations. The expected term is calculated based upon historical employee exercise behavior and the contractual term of the SAR amongst other considerations. The weighted average grant date assumptions used for the SARs granted were as follows for the periods indicated: 2023 Grants SAR value (model conclusion) $ 32.63 Risk-free rate 4.1 % Expected dividend yield 0.0 % Expected volatility 28.4 % Expected term (years) 6.0 Restricted Stock Units We have granted Restricted Stock Units ("RSUs") to directors and certain employees under the 2021 Equity Plan and the 2012 Plan. The RSUs confer the right to receive shares of our common stock at a specified future date or when certain conditions are met. The compensation expense for the RSUs granted is based on the fair value of the RSUs at the date of grant, which is equal to the stock price on the date of grant and is recognized over the requisite service period. The RSUs vest over a maximum of three years and call for the underlying shares to be delivered no later than 30 days following the vesting date unless the participant is subject to a blackout period. In such case, the shares are to be delivered once the blackout restriction has been lifted. It is assumed that all time-based RSUs will vest. We recognize forfeitures of RSUs in the period in which they occur.

We remit the equivalent cash to the appropriate taxing authorities. These net share settlements had the effect of share repurchases by us as we reduced and retired the number of shares that would have otherwise been issued as a result of the vesting. RSUs granted during the nine months ended October 1, 2023, vest at specified future dates with only service requirements. The value of RSUs granted in the nine months ended October 1, 2023, was $19.1 million and is being recognized over the weighted average requisite service period of 2.0 years. During the nine months ended October 1, 2023, 123,672 RSUs vested at a fair value of $11.3 million. Performance-based Restricted Stock Units We have granted certain Performance-based Restricted Stock Units ("PRSUs") under the 2021 Equity Plan and the 2012 Plan. These PRSUs are settled with payouts ranging from zero to 200% of the target award value depending on performance goal achievement. The compensation expense for the PRSUs awarded is based on the fair value of the PRSUs at the date of grant, which is equal to the stock price on the date of grant and is recognized over the requisite service period. The compensation expense for certain PRSUs is determined using the Monte Carlo simulation method. The PRSUs vest over a maximum of three years and call for the underlying shares to be delivered no later than 30 days following the vesting date unless the participant is subject to a blackout period. In such case, the shares are to be delivered once the blackout restriction has been lifted.

Certain awards are settled with payouts ranging from zero to 200% of the target award value depending on achievement. The performance adjustment represents the difference in shares ultimately awarded due to performance attainment above or below target. (2) A portion of the vested PRSUs delivered were net shares settled to cover statutory requirements for income and other employment taxes. We remit the equivalent cash to the appropriate taxing authorities. These net share settlements had the effect of share repurchases by us as we reduced and retired the number of shares that would have otherwise been issued as a result of the vesting.

Restructuring and Related Activities [Abstract]
Restructuring Costs	Restructuring Costs In December 2022, we began implementing a plan intended to improve overall business performance that includes the optimization of our manufacturing capacity and reduction of our overhead and selling, general and administration workforce primarily in our North American Residential reportable segment as well as actions in the Architectural reportable segment and in our head offices (collectively, the "2022 Plan"). The optimization of our manufacturing capacity involves specific plants in the North American Residential segment and costs associated with the closure of these plants and related headcount reductions. Costs associated with the 2022 Plan include severance and closure charges which continue throughout 2023. As of October 1, 2023, we expect to incur approximately $4 million to $9 million of additional charges related to the 2022 Plan. The following tables summarize the restructuring (benefit) costs recorded for the periods indicated: Three Months Ended October 1, 2023 (In thousands) North American Residential Architectural Corporate & Other Total 2022 Plan $ 1,898 $ — $ 2 $ 1,900 Total Restructuring Costs $ 1,898 $ — $ 2 $ 1,900 Three Months Ended October 2, 2022 (In thousands) North American Residential Architectural Corporate & Other Total Other $ (178) $ 23 $ 14 $ (141) Total Restructuring (Benefit) Costs $ (178) $ 23 $ 14 $ (141) Nine Months Ended October 1, 2023 (In thousands) North American Residential Architectural Corporate & Other Total 2022 Plan $ 7,153 $ 863 $ 627 $ 8,643 Total Restructuring (Benefit) Costs $ 7,153 $ 863 $ 627 $ 8,643 Nine Months Ended October 2, 2022 (In thousands) North American Residential Architectural Corporate & Other Total Other $ (359) $ 71 $ 67 $ (221) Total Restructuring (Benefit) Costs $ (359) $ 71 $ 67 $ (221) Cumulative Amount Incurred Through October 1, 2023 (In thousands) North American Residential Architectural Corporate & Other Total 2022 Plan $ 9,284 $ 863 $ 627 $ 10,774 Total Restructuring Costs $ 9,284 $ 863 $ 627 $ 10,774 The changes in the accrual for restructuring by activity were as follows for the periods indicated: (In thousands) January 1, Severance Closure Costs Cash Payments October 1, 2022 Plan $ — $ 5,552 $ 3,091 $ (8,098) $ 545 Total $ — $ 5,552 $ 3,091 $ (8,098) $ 545

Income Taxes	Income Taxes The effective tax rate differs from the Canadian statutory rate of 26.13% primarily due to mix of earnings in foreign jurisdictions that are subject to tax rates which differ from the Canadian statutory rate. In addition, we recognized zero income tax benefit due to the exercise and delivery of share based awards during both the three and nine months ended October 1, 2023, compared to zero and $1.1 million of income tax benefit during the three and nine months ended October 2, 2022, respectively. On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 ("IRA") into law. The IRA includes several changes to existing tax law, including a minimum tax on adjusted financial statement income of applicable corporations and an excise tax on certain corporate stock buybacks. The tax provisions included in the IRA were generally effective beginning January 1, 2023, and no significant impact to the consolidated financial statements resulted from their adoption as of October 1, 2023.

Segment Reporting [Abstract]
Segment Information	Segment Information Our reportable segments are organized and managed principally by end market: North American Residential, Europe and Architectural. The Corporate & Other category includes unallocated corporate costs and the results of immaterial operating segments which were not aggregated into any reportable segment. In addition to similar economic characteristics, we also consider the following factors in determining the reportable segments: the nature of business activities, the management structure directly accountable to our chief operating decision maker for operating and administrative activities, availability of discrete financial information and information presented to the Board of Directors and investors. Our management reviews net sales and Adjusted EBITDA (as defined below) to evaluate segment performance and allocate resources. Net assets are not allocated to the reportable segments. Adjusted EBITDA is a non-GAAP financial measure which does not have a standardized meaning under GAAP and is unlikely to be comparable to similar measures used by other companies. Adjusted EBITDA should not be considered as an alternative to either net income or operating cash flows determined in accordance with GAAP. Adjusted EBITDA is defined as net income (loss) attributable to Masonite adjusted to exclude the following items, as applicable: • depreciation; • amortization; • share based compensation expense; • loss (gain) on disposal of property, plant and equipment; • registration and listing fees; • restructuring costs (benefit); • asset impairment; • loss (gain) on disposal of subsidiaries; • interest expense (income), net; • loss on extinguishment of debt; • other expense (income), net; • income tax expense (benefit); • other items; • loss (income) from discontinued operations, net of tax; and • net income (loss) attributable to non-controlling interest. This definition of Adjusted EBITDA differs from the definitions of EBITDA contained in the indentures governing the 2030 Notes and the 2028 Notes and the credit agreements governing the Term Loan Facility and the ABL Facility . Although Adjusted EBITDA is not a measure of financial condition or performance determined in accordance with GAAP, it is used to evaluate and compare the operating performance of our reportable segments and it is one of the primary measures used to determine employee incentive compensation. Intersegment sales are recorded using market prices. Certain information with respect to reportable segments is as follows for the periods indicated: Three Months Ended October 1, 2023 (In thousands) North American Residential Europe Architectural Corporate & Other Total Net sales $ 553,294 $ 64,813 $ 82,558 $ 4,066 $ 704,731 Intersegment sales (315) (254) (1,900) (15) (2,484) Net sales to external customers $ 552,979 $ 64,559 $ 80,658 $ 4,051 $ 702,247 Adjusted EBITDA $ 108,999 $ 3,698 $ 5,132 $ (10,593) $ 107,236 Three Months Ended October 2, 2022 (In thousands) North American Residential Europe Architectural Corporate & Other Total Net sales $ 579,908 $ 66,109 $ 82,388 $ 4,625 $ 733,030 Intersegment sales (468) (391) (4,545) — (5,404) Net sales to external customers $ 579,440 $ 65,718 $ 77,843 $ 4,625 $ 727,626 Adjusted EBITDA $ 115,092 $ 3,898 $ (219) $ (6,849) $ 111,922 Nine Months Ended October 1, 2023 (In thousands) North American Residential Europe Architectural Corporate & Other Total Net sales $ 1,708,145 $ 194,761 $ 267,751 $ 12,502 $ 2,183,159 Intersegment sales (1,158) (498) (11,373) (15) (13,044) Net sales to external customers $ 1,706,987 $ 194,263 $ 256,378 $ 12,487 $ 2,170,115 Adjusted EBITDA $ 334,451 $ 11,540 $ 17,768 $ (31,901) $ 331,858 Nine Months Ended October 2, 2022 (In thousands) North American Residential Europe Architectural Corporate & Other Total Net sales $ 1,757,820 $ 222,120 $ 236,941 $ 15,641 $ 2,232,522 Intersegment sales (2,040) (2,081) (12,684) — (16,805) Net sales to external customers $ 1,755,780 $ 220,039 $ 224,257 $ 15,641 $ 2,215,717 Adjusted EBITDA $ 367,733 $ 24,307 $ (3,039) $ (34,202) $ 354,799 A reconciliation of our net income attributable to Masonite to consolidated Adjusted EBITDA is set forth as follows for the periods indicated: Three Months Ended Nine Months Ended (In thousands) October 1, 2023 October 2, 2022 October 1, 2023 October 2, 2022 Net income attributable to Masonite $ 41,486 $ 57,037 $ 128,222 $ 183,134 Plus: Depreciation 22,889 17,461 67,355 51,977 Amortization 7,452 4,256 21,915 13,164 Share based compensation expense 4,282 5,556 17,439 16,251 Loss (gain) on disposal of property, plant and equipment 1,779 155 3,319 (1,245) Restructuring costs (benefit) 1,900 (141) 8,643 (221) Interest expense, net 11,913 10,266 39,653 31,098 Other (income) expense, net (1,083) 211 (1,581) (1,604) Income tax expense 12,041 16,376 38,074 59,502 Other items (1) 3,760 — 6,349 — Net income attributable to non-controlling interest 817 745 2,470 2,743 Adjusted EBITDA $ 107,236 $ 111,922 $ 331,858 $ 354,799

Subsequent Event Abstract [Abstract]
Subsequent Event	Subsequent Event Acquisition of Fleetwood On October 19, 2023, the Company completed the acquisition of all of the issued and outstanding limited liability company interests of Fleetwood Aluminum Products, LLC (“Fleetwood”), for $285 million in cash. The Company held back approximately $26 million from the Base Purchase Price to secure the obligations of Sellers to Buyer with respect to any purchase price adjustment and indemnification claims. The total consideration was funded with a combination of cash on hand and borrowings under the ABL facility. Fleetwood is a leading designer and manufacturer of premium, aluminum-framed glass door and window solutions for luxury homes. Their products include multi-slide and pocket glass patio doors, pivot and hinged glass entry doors and folding glass door wall systems, as well as accompanying premium window products. The acquisition aligns with the Doors That Do More TM strategy focused on bringing differentiated door systems to the residential market. The acquisition will be accounted for as a business combination, with the goodwill being non-deductible for tax purposes. The allocation of the purchase price to the underlying assets acquired and liabilities assumed is subject to a formal valuation process, which has not yet been completed. The major classes of assets acquired will include trade receivables, inventories, trade payables and goodwill and intangibles. Our 2023 operating results will include the results from Fleetwood from the date of acquisition. Based on the timing of the acquisition and lack of available information, we determined it to be impracticable to disclose a preliminary purchase price allocation at this time.

Accounting Policies [Abstract]
Adoption of Recent Accounting Pronouncements	Adoption of Recent Accounting Pronouncements In December 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2021-10, "Government Assistance," which requires annual disclosures that increase the transparency of transactions involving government grants, including (1) the types of transactions, (2) the accounting for those transactions and (3) the effect of those transactions on an entity's financial statements. The guidance is effective for annual periods beginning after December 15, 2021, with early adoption permitted. We adopted the new guidance as of January 3, 2022, the beginning of fiscal year 2022, and the adoption did not have a material impact on our financial statements. In October 2021, the FASB issued ASU 2021-08, "Accounting for Contract Assets and Contract Liabilities from Contracts with Customers," which clarifies that an acquirer of a business should recognize and measure contract assets and contract liabilities in a business combination in accordance with ASU 2014-09, "Revenue from Contracts with Customers" as if the entity had originated the contracts. We adopted the new guidance as of January 1, 2023, the beginning of fiscal year 2023, and the adoption did not have a material impact on our financial statements.
