Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	1. Description of Business PGT Innovations, Inc. (“PGTI”, “we,” or the “Company”), formerly named PGT, Inc., is a leading manufacturer of impact-resistant aluminum and vinyl-framed windows and doors and offers a broad range of fully customizable window and door products. The majority of our sales are to customers in the state of Florida; however, we also sell products in many other states, the Caribbean, Canada, and in South and Central America. Our acquisition of Eco Enterprises ("Eco Acquisition") in February 2021 expands our range of product offerings in our major market of southeast Florida. We also have sales of products that are designed to unify indoor and outdoor living spaces, through our Western Windows Systems’ (“WWS”) division, and most of its sales are in the western United States. Our acquisitions of Anlin Windows and Doors in October 2021 and Martin Door Holdings, Inc. ("Martin") in October 2022 expanded our presence in the west. The acquisition of Martin, which produces residential and commercial garage doors, expands the Company into building products adjacent to its portfolio of window and door brands. Products are sold primarily through an authorized dealer and distributor network. We began selling window products in the direct-to-consumer channel, a “factory-direct” sales model, through our acquisition of NewSouth Windows Solutions in February 2020. We were incorporated in the state of Delaware on December 16, 2003, as JLL Window Holdings, Inc., with primary operations in North Venice, Florida. On February 15, 2006, our Company was renamed PGT, Inc. On December 14, 2016, we announced that we changed our name to PGT Innovations, Inc. and, effective on December 28, 2016, the listing of our common stock was transferred to the New York Stock Exchange (“NYSE”) from the NASDAQ Global Market, and began trading on the NYSE under its existing ticker symbol of “PGTI”. As of December 31, 2022, we had major manufacturing operations in Florida, in North Venice, Ft. Myers, Tampa, and in the greater Miami area. We also have manufacturing operations in Arizona, California and, with the Martin Acquisition, Utah. Additionally, we have two glass tempering and laminating plants and one insulation glass plant located in North Venice. All references to PGTI or our Company apply to the consolidated financial statements of PGT Innovations, Inc. unless otherwise noted.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Fiscal period Our fiscal year consists of 52 or 53 weeks ending on the Saturday nearest December 31 of the related year. The years ended December 31, 2022, and January 1, 2022, consisted of 52 weeks. The year ended January 2, 2021 consisted of 53 weeks. Principles of consolidation The consolidated financial statements present the results of the operations, financial position and cash flows of PGTI, and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. We are consolidating all wholly owned subsidiaries, as well as Eco, based on the 75 % majority ownership. We refer to Note 20 for our accounting policies relating to the non-redeemable minority interest. Segment information We operate as two segments based on geography: the Southeast segment and the Western segment. See Note 19 for more information. Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. Revenue recognition Revenue is recognized when our performance obligations are satisfied. Generally, our performance obligations are satisfied over time when control of our products is transferred, and revenue is recognized at a single point in time, when title transfers to our customer for product shipped or when services are provided. Revenues are recorded net of any sales incentives. See Note 4, “Revenue Recognition and Contracts with Customers.” Cost of sales Cost of sales represents costs directly related to the production of our products. Primary costs include raw materials, direct labor, and manufacturing overhead, which consist of salaries, wages, employee benefits, utilities, maintenance, lease costs and depreciation. Shipping and handling costs Shipping and handling costs incurred in the purchase of materials used in the manufacturing process are included in cost of sales. Costs relating to shipping, handling and distribution of finished products to our customers are included in selling, general and administrative expenses and totaled $ 75.1 million, $ 62.4 million and $ 39.3 million for the years ended December 31, 2022, January 1, 2022, and January 2, 2021, respectively. Advertising We expense advertising costs as incurred. Advertising expense, which is included in selling, general and administrative expenses, was $ 22.7 million, $ 15.8 million and $ 11.6 million for the years ended December 31, 2022, January 1, 2022 and January 2, 2021, respectively. NewSouth, acquired on February 1, 2020, relies heavily on advertising, consistent with its sales-direct-to-homeowner business model. Cash and cash equivalents Cash and cash equivalents consist of cash on hand or highly liquid investments with an original maturity date of three months or less when purchased. Accounts receivable, net In the ordinary course of business, we extend credit to qualified dealers and distributors, generally on a non-collateralized basis. The Company maintains an allowance for credit losses which is based on management’s assessments of the amount which may become uncollectible in the future and is determined through consideration of our write-off history, specific identification of uncollectible accounts based in part on the customer’s past due balance (based on contractual terms), and consideration of prevailing economic and industry conditions. Uncollectible accounts are written off after repeated attempts to collect from the customer have been unsuccessful. December 31, January 1, 2022 2022 (in thousands) Accounts receivable $ 173,763 $ 145,923 Less: Allowance for credit losses ( 13,656 ) ( 4,702 ) Accounts receivable, net $ 160,107 $ 141,221 Self-insurance reserves We are primarily self-insured for employee health benefits and workers’ compensation claims prior to 2010 and after 2017. Provisions for losses under these programs are recorded based on the Company’s estimates of the aggregate liabilities for the claims incurred. Accruals for healthcare claims and workers’ compensation are included in accrued liabilities in the accompanying consolidated balance sheets. Warranty expense We have warranty obligations with respect to most of our manufactured products. Warranty periods, which vary by product components, generally range from 1 to 10 years , although the warranty period for a limited number of specifically identified components in certain applications is a lifetime. However, the majority of the products sold have warranties on components which range from 1 to 3 years . The Company has recorded a reserve for estimated warranty and related costs based on historical experience and periodically adjusts these provisions to reflect actual experience. During 2022, we recorded warranty expense at an average rate of 2.1 % of sales. This rate approximates the average rate of 2.0 % of sales recorded in 2021. The average rate of 2.0 % of sales in 2021 compares to an average rate of 1.7 % of sales recorded in 2020. The increase in our warranty expense rate in 2021, compared to 2020 was a result of costs associated with higher levels of warranty repair experience on larger commercial projects than experienced in 2020, which resulted in warranty costs incremental to those we would incur in the normal course of business. The increase in our warranty expense in 2021, compared to 2020, was also affected by costs associated with the wind-down of the commercial business of NewSouth in the first quarter of 2021, which resulted in warranty costs incremental to those we would incur in the normal course of business. We assess the adequacy of our warranty accrual on a quarterly basis, and adjust the previous amounts recorded, if necessary, to reflect the change in estimate of the future costs of claims yet to be serviced. The following provides information with respect to our warranty accrual. Accrued Warranty Beginning of Acquired (Acquisition Charged to Adjustments Settlements End of (in thousands) Year ended December 31, 2022 $ 13,504 $ ( 2,537 ) $ 31,223 $ 698 $ ( 27,500 ) $ 15,388 Year ended January 1, 2022 $ 8,001 $ 4,150 $ 23,637 $ ( 1,440 ) $ ( 20,844 ) $ 13,504 Year ended January 2, 2021 $ 6,244 $ 3,515 $ 15,256 $ 266 $ ( 17,280 ) $ 8,001 During the third quarter of 2022, we finalized our calculation of the reserve for warranty obligations assumed in the Anlin Acquisition. As a result, we recorded an acquisition adjustment to decrease Anlin's warranty reserve by $ 2.5 million from its initial estimate in our then preliminary allocation of the fair value of assets acquired and liabilities assumed, resulting in an equal decrease in goodwill. The accrual for warranty is included in accrued liabilities and other liabilities, depending on estimated settlement date, in the consolidated balance sheets as of December 31, 2022 and January 1, 2022. The portion of warranty expense related to the issuance of product of $ 3.9 million, $ 3.0 million and $ 3.8 million is included in cost of sales in the consolidated statements of operations for the years ended December 31, 2022, January 1, 2022, and January 2, 2021, respectively. The portion related to servicing warranty claims including costs of the service department personnel is included in selling, general and administrative expenses in the consolidated statements of operations, and is $ 28.1 million, $ 19.2 million and $ 11.7 million, respectively, for the years ended December 31, 2022, January 1, 2022, and January 2, 2021. Inventories Inventories consist principally of raw materials purchased for the manufacture of our products. We have limited work-in-progress and finished goods inventory as most products are custom, made-to-order products manufactured under noncancelable purchase orders and therefore are recognized as costs of sales relating to revenue recognized over time during the manufacturing process. All inventories are stated at the lower of cost (first-in, first-out method) or net realizable value. The reserve for obsolescence, which was immaterial at December 31, 2022 and January 1, 2022, is based on management’s assessment of the amount of inventory that may become obsolete in the future and is determined through Company history, specific identification and consideration of prevailing economic and industry conditions. Inventories consist of the following: December 31, January 1, 2022 2022 (in thousands) Raw materials $ 109,679 $ 87,164 Work in progress 916 3,248 Finished goods 2,077 1,028 Inventories $ 112,672 $ 91,440 Property, plant and equipment Property, plant and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. Depreciable assets are assigned estimated lives as follows: Building and improvements 5 to 40 years Leasehold improvements Shorter of lease term or estimated useful life Furniture and equipment 3 to 10 years Vehicles 5 to 10 years Computer software 3 years Maintenance and repair expenditures are charged to expense as incurred. Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets, current portion of operating lease liability, and operating lease liability, less current portion, on our consolidated balance sheets. The Company currently does not have any finance leases. Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease right-of-use asset also includes any up-front lease payments made and initial direct costs incurred, less lease incentives received. Our lease terms may include options to extend or terminate the lease. Lease expense is recognized on a straight-line basis over the lease term. We elected the practical expedient to not separate lease and non-lease components for all classes of underlying assets. Long-lived assets We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of long-lived assets to future undiscounted net cash flows expected to be generated . If such assets are considered to be impaired, the impairment recognized is the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell, and depreciation is no longer recorded. Computer software We capitalize costs associated with software developed or obtained for internal use when both the preliminary project stage is complete, and it is probable that computer software being developed will be completed and placed in service. Capitalized costs include: (i) external direct costs of materials and services consumed in developing or obtaining computer software, (ii) payroll and other related costs for employees who are directly associated with and who devote time to the software project, and (iii) interest costs incurred, when material, while developing internal-use software. Capitalization of such costs ceases no later than the point at which the project is substantially complete and ready for its intended purpose. Capitalized software as of December 31, 2022, and January 1, 2022, was $ 31.7 million and $ 31.8 million, respectively. Accumulated depreciation of capitalized software was $ 30.3 million and $ 29.0 million as of December 31, 2022, and January 1, 2022, respectively. Amortization expense for capitalized software was $ 3.0 million, $ 3.7 million, and $ 4.1 million for the years ended December 31, 2022, January 1, 2022, and January 2, 2021, respectively. We review the carrying value of capitalized software and development costs for impairment in accordance with our policy pertaining to the impairment of long-lived assets. Goodwill Goodwill is calculated as the excess of the consideration paid in a business combination over the fair value of the identifiable net assets acquired. We test goodwill for impairment at the reporting unit level at least annually or whenever events or circumstances indicate that the carrying value of goodwill may not be recoverable. Our annual test for impairment is done on the first date of our fiscal fourth quarter. We consider various qualitative factors, including macroeconomic and industry conditions, financial performance of the Company and changes in the stock price of the Company to determine whether it is necessary to perform a quantitative test for goodwill impairment. If we believe, as a result of our qualitative assessment, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Under the quantitative test, goodwill is tested under a one-step method for impairment at a level of reporting referred to as a reporting unit. This quantitative analysis involves identifying potential impairment by comparing the fair value of each reporting unit with its carrying amount and, if the carrying amount of a reporting unit exceeds its fair value, then a charge for goodwill impairment will be recognized in the amount by which a reporting unit’s carrying value exceeds its fair value. For our Southeast and Western reporting units, based on qualitative assessments, we concluded that quantitative assessments were not required to be performed. See Note 7 for further discussion of the goodwill of our reporting units. Trade names The Company has indefinite-lived intangible assets in the form of certain trade names. The impairment evaluation of the carrying amount of our indefinite-lived trade names is conducted annually, or more frequently, if events or changes in circumstances indicate that they might be impaired. We have the option of performing a qualitative assessment of impairment to determine whether any further quantitative testing for impairment is necessary. If we elect to bypass the qualitative assessment or if we determine, based on qualitative factors, that it is more likely than not that the fair value of our indefinite-lived trade names is less than the carrying amount, an evaluation is performed by comparing their carrying amount to their estimated fair values. If the estimated fair value is less than the carrying amount of the indefinite-lived trade name, then an impairment charge is recorded to reduce the carrying value to its estimated fair value. The estimated fair value is determined using the relief from royalty method that is based upon the discounted projected cost savings (value) attributable to ownership of our trade names, our only indefinite-lived intangible assets. Other than the WinDoor trade name, based on qualitative assessments for 2022, the Company concluded it was more likely than not the fair value of the indefinite-lived intangible assets exceeded their carrying values. For the WinDoor trade name, we concluded that a quantitative assessment was required, given the recent decrease in sales of the brand and given the narrow excess of the fair value over the carrying value of our WinDoor trade name in our prior quantitative assessment, which resulted in an impairment charge of $ 7.4 million in the year ended December 31, 2022. We review the carrying value of our finite-lived trade name in accordance with our policy for long-lived assets. See Note 7 for further discussion of our trade name. Derivative financial instruments We utilize certain derivative instruments, from time to time, including forward contracts to manage variability in cash flow associated with commodity market price risk exposure in the aluminum market. We do not enter into derivatives for speculative purposes. Concentrations of credit risk Financial instruments, which potentially subject us to concentrations of credit risk, consist principally of cash and cash equivalents, trade accounts receivable and contract assets. Accounts receivable and contract assets are due primarily from dealers and distributors of building materials, and other companies in the construction industry, primarily located in Florida, California, Texas, Arizona and, with the Martin Acquisition in October 2022, Utah. Credit is extended based on an evaluation of the customer’s financial condition and credit history, and generally collateral is not required. The Company maintains an allowance for potential credit losses on trade receivables and contract assets. We maintain our cash with several financial institutions, the balance of which exceeds federally insured limits. At December 31, 2022 and January 1, 2022, our cash balance exceeded the insured limit by $ 61.4 million and $ 89.0 million, respectively. Comprehensive income (loss) The Company reports comprehensive income (loss), defined as the total of net income and other comprehensive income (loss), which is composed of all other non-owner changes in equity, and the components thereof, in its consolidated statements of comprehensive income. The components of other comprehensive income (loss) relate to gains and losses on cash flow hedges. Reclassification adjustments reflecting such gains and losses are recorded as income in the same period as the hedged items affect earnings. Stock-based compensation We use a fair-value based approach for measuring stock-based compensation and record compensation expense over an award’s vesting period based on the award’s fair value at the date of grant. Our Company’s awards vest based on service conditions and certain performance conditions and compensation expense is recognized generally on a straight-line basis for each separately vesting portion of an award. Stock-based compensation expense is recognized only for those awards that ultimately vest. Income and Sales Taxes We account for income taxes utilizing the liability method. Deferred income taxes are recorded to reflect consequences on future years of differences between financial reporting and the tax basis of assets and liabilities measured using the enacted statutory tax rates and tax laws applicable to the periods in which differences are expected to affect taxable earnings. We have no liability for unrecognized tax benefits. However, should we accrue for such liabilities, when and if they arise in the future, we will recognize interest and penalties associated with uncertain tax positions as part of our income tax provision. Income taxes relating to gains and losses on our cash flow hedges are released at the same time as the underlying transactions are realized. Interest and penalties on income taxes, if any, are recorded as income taxes. Refer to Note 12 for additional information regarding the Company’s income taxes. Sales taxes collected from customers have been recorded on a net basis. Net income per common share Basic earnings per share (“EPS”) available to PGT Innovations, Inc. common stockholders is computed using the two-class method by dividing net income attributable to common shareholders, after deducting the redemption adjustment related to the redeemable noncontrolling interest, by the average number of common shares outstanding during the period. Diluted EPS available to PGT Innovations, Inc. common stockholders is computed using the two-class method by dividing net income attributable to common shareholders, after deducting the redemption adjustment related to the redeemable noncontrolling interest, by the average number of common shares outstanding, including the dilutive effect of common stock equivalents computed using the treasury stock method and the average share price during the period. Forfeiture of unvested equity are recognized on an actual basis, at the same time as the equity is forfeited. There were no anti-dilutive shares outstanding for the years ended December 31, 2022 and January 1, 2022. Our weighted average number of diluted shares outstanding excludes underlying securities of 23 thousand for the year ended January 2, 2021, because their effects were anti-dilutive. The table below presents the calculation of basic and diluted earnings per share, including a reconciliation of weighted average common shares: Year Ended December 31, January 1, January 2, 2022 2022 2021 (in thousands, except per share amounts) Net income $ 98,405 $ 35,196 $ 45,108 Less: Net income attributable to redeemable non-controlling interest ( 1,523 ) ( 2,318 ) — Net income attributable to the Company 96,882 32,878 45,108 Change in redemption value of redeemable non-controlling interest 2,000 ( 6,081 ) — Net income attributable to common shareholders $ 98,882 $ 26,797 $ 45,108 Weighted-average common shares - Basic 59,926 59,518 58,887 Add: Dilutive shares from equity plans 393 540 473 Weighted-average common shares - Diluted 60,319 60,058 59,360 Weighted average number of common shares outstanding: Basic $ 1.65 $ 0.45 $ 0.77 Diluted $ 1.64 $ 0.45 $ 0.76 Supplemental cash flow information and non-cash activity The table below presents supplemental cash flow information and non-cash activity for the years ended December 31, 2022, January 1, 2022, and January 2, 2021: Year Ended December 31, January 1, January 2, (in thousands) 2022 2022 2021 Supplemental cash flow information: Interest paid $ 27,948 $ 32,636 $ 25,156 Income tax payments, net of refunds $ 21,499 $ 12,166 $ 9,242 Non-cash activity: Establish right-of-use asset $ 29,031 $ 65,678 $ 19,185 Establish operating lease liability $ ( 29,031 ) $ ( 65,678 ) $ ( 19,185 ) Reclassification of accounts receivable to notes receivable $ 4,225 $ — $ 1,437 Property, plant and equipment additions in accounts payable $ 565 $ 772 $ 61

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	3. Recent Accounting Pronouncements Accounting Pronouncements Recently Adopted Business Combinations - Contracts Assets and Liabilities On October 28, 2021, the FASB issued ASU 2021-08,1 which amends ASC 805-20 to “require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination.” Under current GAAP, an acquirer generally recognizes such items at fair value on the acquisition date. This standard was effective beginning December 31, 2022 . Early adoption was permitted. The Company adopted this standard for the year ended January 1, 2022. The adoption of this standard did not have any impact on our consolidated financial statements. Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” and in January 2021, subsequent amendment to the initial guidance, ASU 2021-01, “Reference Rate Reform (Topic 848): Scope” (collectively, “Topic 848”). In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848,” which defers its sunset date to June 2023 as a result of the UK Financial Conduct Authority's extension of the LIBOR cessation date to June 30, 2023. Topic 848 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The guidance generally can be applied currently, through June 30, 2023. Topic 848 has had and will have no impact on the reference rates in our financing agreements. Accounting Pronouncements Recently Issued, Not Yet Adopted Disclosure of Supplier Finance Program Obligations In September 2022, the FASB issued ASU 2022-04, “Supplier Finance Programs: Disclosure of Supplier Finance Program Obligations,” to improve the disclosures of supplier finance programs. Specifically, the ASU requires disclosure of key terms of the supplier finance programs and a rollforward of the related obligations. The amendments in this ASU do not affect the recognition, measurement, or financial statement presentation of obligations covered by supplier finance programs. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2022, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. The Company does not engage in supplier finance programs and, therefore, does not expect to add any incremental disclosures required by ASU 2022-04.

Revenue from Contract with Customer [Abstract]
Revenue Recognition and Contracts with Customers	4. Revenue Disaggregation of Revenue from Contracts with Customers As discussed in Note 1, we have two reportable segments: our Southeast segment and our Western segment. See Note 19 for more information. The following table provides information about our net sales by reporting segment, product category and market for the years ended December 31, 2022, January 1, 2022, and January 2, 2021 (in millions): Year Ended December 31, January 1, January 2, Disaggregation of revenue: 2022 2022 2021 Reporting segment: Southeast $ 1,110.4 $ 968.7 $ 752.4 Western 381.6 192.8 130.2 Total net sales $ 1,492.0 $ 1,161.5 $ 882.6 Product category: Impact-resistant window and door products $ 878.8 $ 787.2 $ 630.2 Non-impact window and door products 613.2 374.3 252.4 Total net sales $ 1,492.0 $ 1,161.5 $ 882.6 Market: New construction $ 625.1 $ 489.9 $ 402.5 Repair and remodel 866.9 671.6 480.1 Total net sales $ 1,492.0 $ 1,161.5 $ 882.6 The Company’s Western segment includes both custom and volume products. This segment’s volume products are not made-to-order and are of standardized sizes and design specifications. Therefore, the Company’s assessment is that the Western segment’s volume products have alternative uses, and that control of these products passes to the customer at a point in time, which is typically when the product has been delivered to the customer. For the years ended December 31, 2022, January 1, 2022, and January 2, 2021, the Western segment’s net sales of its volume products were $ 111.5 million, $ 83.0 million and $ 53.2 million, respectively. Contract Balances Contract assets represent sales recognized in excess of billings related to finished goods not yet shipped and certain unused glass components not yet placed into the production process for which revenue is recognized over time as noted above. Contract liabilities relate to customer deposits at the end of reporting periods. At December 31, 2022 and January 1, 2022, those contract liabilities totaled $ 39.1 million and $ 45.2 million, respectively, of which $ 33.4 million and $ 37.0 million, respectively, are classified within accrued liabilities, and $ 5.7 million and $ 8.2 million, respectively, are classified within contract assets, net, in the accompanying consolidated balance sheets at December 31, 2022 and January 1, 2022. Because of the short-term nature of our performance obligations, as discussed below, substantially all of our performance obligations are satisfied within the quarter following the end of a reporting period. As such, substantially all of the contract liabilities at January 1, 2022 were satisfied in the first quarter of 2022, and contract assets at January 1, 2022 were transferred to accounts receivable in the first quarter of 2022. Also, substantially all of the contract liabilities at December 31, 2022 will be satisfied in the first quarter of 2023, and contract assets at December 31, 2022 will be transferred to accounts receivable in the first quarter of 2023. Contract liabilities at December 31, 2022 represents cash received during the three-month period ended December 31, 2022, excluding amounts recognized as revenue during that period. Contract assets at December 31, 2022 represents revenue recognized during the three-month period ended December 31, 2022, excluding amounts transferred to accounts receivable during that period. Contract liabilities at January 1, 2022 represents cash received during the three-month period ended January 1, 2022, excluding amounts recognized as revenue during that period. Contract assets at January 1, 2022 represents revenue recognized during the three-month period ended January 1, 2022, excluding amounts transferred to accounts receivable during that period.

Business Combinations [Abstract]
Acquisitions	5. Acquisitions Martin Doors On October 14, 2022 , we completed the acquisition of the Martin Doors brand. The acquisition was done by WWS Acquisition, LLC, a Missouri limited liability company, indirectly wholly-owned by PGT Innovations, Inc., which acquired all of the shares of stock of Martin Door Holdings, Inc., a Utah corporation, headquartered in Salt Lake City, Utah, a custom manufacturer of overhead garage doors and hardware serving the Western U.S. (the "Martin Acquisition"), pursuant to that certain Share Purchase Agreement dated as of October 14, 2022 (the “Martin Purchase Agreement”). The fair value of consideration transferred in the Martin Acquisition was $ 187.8 million, composed entirely of cash, including $ 185.0 million for purchase price and $ 2.8 million in estimated working capital adjustments paid at closing. The cash portion of the Martin Acquisition of $ 98.4 million was financed with borrowings under the fifth amendment of our 2016 Credit Agreement due 2027, with the remaining $ 89.4 million fund with cash on hand. Generally, cash on hand for the Martin Acquisition was provided by cash generated through operations. Purchase Price Allocation The preliminary estimated fair value of assets acquired, and liabilities assumed as of the closing date, are as follows: Preliminary Accounts receivable $ 6,653 Inventories 9,543 Contract assets, net 5,242 Prepaid expenses and other assets 90 Property and equipment 11,422 Operating lease right-of-use asset 12,259 Intangible assets 91,900 Total assets acquired 137,109 Accounts payable ( 2,482 ) Accrued and other liabilities ( 1,270 ) Deferred tax liabilities ( 23,604 ) Operating lease liability ( 12,259 ) Total liabilities assumed ( 39,615 ) Net assets acquired 97,494 Goodwill 90,300 Fair value of consideration transferred $ 187,794 Consideration: Cash $ 187,794 Fair value of consideration transferred $ 187,794 The fair value of certain working capital related items, including Martin’s accounts receivable, prepaid expenses and other assets, and accounts payable and accrued and other liabilities, approximated their book values at the date of the Martin Acquisition. The fair value of inventory was estimated by major category, at net realizable value, which we believe approximates the price a market participant could achieve in a current sale. The substantial majority of inventories at the acquisition date was comprised of raw materials. The fair value of property and equipment and remaining useful lives were estimated by management, with the assistance of a third-party valuation firm, using the cost approach. Valuations of the intangible assets were done using income and royalty relief approaches based on projections provided by management, which we consider to be Level 3 inputs, with the assistance of a third-party valuations firm. Certain aspects of our intangible valuations, as well as the amount of deferred tax liabilities acquired in the Martin Acquisition are still being finalized and subject to change. We incurred acquisition costs totaling $ 4.8 million relating to legal expenses, representations and warranties insurance, diligence, accounting and other services in the Martin Acquisition, classified as selling, general and administrative expenses in the accompanying consolidated statements of operations for the year ended December 31, 2022. Because the Martin Acquisition was an acquisition of stock, Martin's assets and liabilities retain their tax bases at the time of the acquisition. Therefore, none of the identifiable intangible assets or goodwill acquired in the Martin Acquisition are deductible for tax purposes. As of December 31, 2022, goodwill is estimated to be $ 90.3 million. Martin's goodwill is included as part of the Western reporting unit. We believe Martin's goodwill relates to the expansion of our footprint in a key, strategic market we have identified as a geographic area of growth for our Company, as well as being a key component of our strategy to expand into adjacent building material products, other than windows and doors. Pro forma results of operations as well as net sales and income attributable to the Martin Acquisition are not presented as it did not have a material impact on our results of operations, Valuation of Identified Intangible Assets The valuation of the identifiable intangible assets acquired in the Martin Acquisition and our estimate of their respective useful lives are as follows: Initial Preliminary Useful Life Valuation (in years) (in thousands) Trade name $ 24,000 indefinite Customer relationships 52,700 15 Customer-related backlog (amortized in 2022) 400 < 1 Developed technology 14,600 3 - 14 Non-compete-related intangible 200 5 Intangible assets, net $ 91,900 Anlin Windows & Doors On October 25, 2021 , we completed the acquisition of Anlin Windows & Doors. The acquisition was done by Western Window Holding LLC, a Delaware limited liability company, indirectly wholly-owned by PGT Innovations, Inc., which acquired substantially all of the assets, properties and rights owned, used or held for use in the business, as operated by Anlin Industries, a California corporation, of manufacturing vinyl windows and doors for the replacement market and the new construction market, and all activities conducted in connection therewith (the "Anlin Acquisition"), pursuant to that certain Asset Purchase Agreement dated as of September 1, 2021 (the “Anlin Purchase Agreement”), by and among the Company, and Anlin Industries. The fair value of consideration transferred in the Anlin Acquisition was $ 121.7 million, composed of $ 115.0 million in cash, including $ 113.5 million for purchase price and $ 1.5 million in working capital adjustments, including $ 0.8 million paid during the three months ended October 1, 2022, and fair value of contingent consideration of $ 6.7 million, discussed in greater detail below. The Anlin Purchase Agreement provides for the potential for earn-out contingency payments to sellers should Anlin achieve a certain level of earnings before interest, taxes, depreciation and amortization, ("Anlin EBITDA"), as defined in the Anlin Purchase Agreement, for its fiscal years of 2021 and 2022, of up to $ 3.2 million to be paid out by March 31, 2022, and of up to $ 9.5 million to be paid out by March 31, 2023, respectively. We had recorded a preliminary earn-out contingent liability of $ 5.9 million as of our year ended January 1, 2022, which represented its then estimated fair value based on probability adjusted levels of estimated Anlin EBITDA. Estimated Anlin EBITDA is a significant input that is not observable in the market, which ASC 820 considers to be a Level 3 input. In the first quarter of 2022, we finalized the fair value of the earn-out contingency, which we adjusted by an additional $ 0.8 million, to a total of $ 6.7 million of estimated fair value of contingent consideration as of the effective date of the Anlin Acquisition. This amount included $ 2.4 million for the contingent consideration relating to 2021 Anlin EBITDA and $ 4.3 million for the contingent consideration relating to the 2022 Anlin EBITDA. The first contingent consideration payment was agreed to be $ 2.7 million, which exceeded its estimated fair value by $ 0.3 million. This excess is classified as selling, general and administrative expenses in the accompanying consolidated statement of operations for year ended December 31, 2022. The payment was made during the second quarter of 2022 after both parties agreed to extend the deadline for the first payment past the March 31, 2022 due date stated in the Anlin Purchase Agreement. As of the end of 2022, we updated our estimate of the fair value of the contingent consideration relating to 2022 Anlin EBITDA, which was estimated to be $ 9.5 million, the maximum potential payout for fiscal year 2022 under the Anlin Purchase Agreement, which we expect to pay-out in the first quarter of 2023. As such, we recognized an expense of approximately $ 5.1 million, representing the difference between this updated estimated fair value, and the fair value estimated in our purchase price allocation, classified as selling, general and administrative expenses in the accompanying consolidated statement of operations for the year ended December 31, 2022. For tax purposes, contingent consideration does not become part of tax goodwill until paid. As such, the amount of goodwill deductible for tax purposes will not be finalized until the payment of the contingent consideration for 2022 is known. As of December 31, 2022, the estimated fair value of the contingent consideration in the allocation relating to this remaining payment was $ 4.3 million, and goodwill according to the current allocation of consideration is $ 9.6 million. As such, as of December 31, 2022, the amount of goodwill estimated to be tax deductible is the difference of $ 5.3 million. Anlin's goodwill is included as part of the Western reporting. We believe Anlin's goodwill relates to the expansion of our footprint in a key, strategic market we have identified as a geographic area of growth for our Company. Our estimate of the amount of tax deductible goodwill may change as the amounts of the payments of contingent consideration are finalized.

Goodwill We perform our annual goodwill impairment testing on the first day of our fiscal fourth quarter of each year, and at interim periods if needed based on occurrence of triggering events.

The qualitative assessments indicated that it was more likely than not that the fair value of each reporting unit exceeded its respective carrying value. As of December 31, 2022, and January 1, 2022, the carrying value of our Southeast reporting unit goodwill is $ 228.3 million and $ 226.8 million, respectively. As of December 31, 2022, and January 1, 2022, the carrying value of our Western reporting unit goodwill is $ 232.1 million and $ 137.8 million, respectively. Indefinite-Lived Intangible Assets We perform our annual indefinite-lived intangible asset impairment testing on the first day of our fiscal fourth quarter of each year, and at interim periods if needed based on occurrence of triggering events. Given the narrow excess of fair value over carrying value of our WinDoor trade name in the first quarter of 2020, the last time we performed a quantitative assessment of our WinDoor trade name, and recent decrease in sales of our WinDoor brand, we determined such conditions represented triggering events and that we should complete a quantitative impairment test of our WinDoor trade name as of our annual impairment test date of the first day of our fourth quarter of 2022. Based on our revised modeling, which included our assumptions regarding future revenue, which we consider to be a Level 3 input, using the relief-from-royalty method, we concluded that the fair value of our WinDoor trade name was less than its carrying value, which resulted in an impairment of our WinDoor trade name of $ 7.4 million in our fourth quarter of 2022. As of December 31, 2022, and January 1, 2022, the carrying value of our WinDoor tradename was $ 11.0 million and $ 18.4 million, respectively. For our other indefinite-lived trade names, we completed qualitative assessments of these assets on the first day of our fourth quarter of 2022. These qualitative assessments included an evaluation of relevant events and circumstances that existed at the date of our assessment. Those events and circumstances included conditions specific to our other indefinite-lived trade names, such as the industry in which we use these other indefinite-lived trade names, our competitive environment, the availability and costs of raw materials and labor, the financial performance of our Company, and factors related to the markets in which our Company operates. We also considered that, for our other indefinite-lived trade names, no new impairment indicators were identified since the dates of our prior assessments, which were qualitative assessments all other indefinite-lived intangibles other than goodwill. Based on these assessments, we concluded that it is more likely than not that the fair values of our other indefinite-lived trade names exceed their carrying values. As of December 31, 2022, and January 1, 2022, excluding the WinDoor trade name, the carrying values of other indefinite-lived trade names were $ 214.0 million and $ 193.7 million, respectively.

The 2021 Senior Notes due 2029 are jointly and severally and fully and unconditionally guaranteed on a senior unsecured basis by each of the Company’s existing and future restricted subsidiaries, other than any restricted subsidiary of the Company that does not guarantee the existing senior secured credit facilities or any permitted refinancing thereof. The 2021 Senior Notes due 2029 are senior unsecured obligations of the Company and the guarantors, respectively, and rank pari passu in right of payment with all existing and future senior debt and senior to all existing and future subordinated debt of the Company and the guarantors. The 2021 Senior Notes due 2029 were offered under Rule 144A of the Securities Act, and in transactions outside the United States under Regulation S of the Securities Act, and have not been, and will not be, registered under the Securities Act. The 2021 Senior Notes due 2029 mature on October 1, 2029 . Interest on the 2021 Senior Notes due 2029 is payable semi-annually, in arrears, beginning on April 1, 2022, with interest accruing at a rate of 4.375 % per annum from September 24, 2021. We incurred financing costs relating to bank fees and professional services costs relating to the offering and issuance of the 2021 Senior Notes due 2029 totaling $ 8.7 million, which included a 1.25 % lender spread on the total principal value of the 2021 Senior Notes due 2029, or $ 7.2 million, and $ 1.5 million of other costs, all of which are being amortized under the effective interest method. As of December 31, 2022, the face value of debt outstanding under the 2021 Senior Notes due 2029 was $ 575.0 million, and accrued interest totaled $ 6.4 million. Proceeds from the 2021 Senior Notes due 2029 were used, in part, to redeem in full the $ 425.0 million of 2018 Senior Notes due 2026, including the related fees, costs and prepayment call premium of $ 21.5 million, representing 5.063 % of the $ 425.0 million face value then outstanding, prepay the outstanding term loan borrowings under the then existing 2016 Credit Agreement due 2024 of $ 54.0 million and the related fees and costs, and finance the Anlin Acquisition in the fourth quarter of 2021. See Note 5, Acquisitions, for a discussion of the Anlin Acquisition. The indenture for the 2021 Senior Notes due 2029 gives us the option to redeem some or all of the 2021 Senior Notes due 2029 at the redemption prices and on the terms specified in the indenture governing the 2021 Senior Notes due 2029. The indenture governing the 2021 Senior Notes due 2029 does not require us to make any mandatory redemptions or sinking fund payments. However, upon the occurrence of a change of control, as defined in the indenture, the Company is required to offer to repurchase the notes at 101 % of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase. We also may make optional redemptions at various premiums including a make-whole call at the then current treasury rate plus 50 basis points prior to October 1, 2024, then 102.188 % on or after August 1, 2024, 101.094 % on or after August 2025, then at 100.000 % on or after August 1, 2026. The indenture for the 2021 Senior Notes due 2029 includes certain covenants limiting the ability of the Company and any guarantors to, (i) incur additional indebtedness; (ii) pay dividends on or make distributions in respect of capital stock or make certain other restricted payments or investments; (iii) enter into agreements that restrict distributions from restricted subsidiaries; (iv) sell or otherwise dispose of assets; (v) enter into transactions with affiliates; (vi) create or incur liens; merge, consolidate or sell all or substantially all of the Company’s assets; (vii) place restrictions on the ability of subsidiaries to pay dividends or make other payments to the Company; and (viii) designate the Company’s subsidiaries as unrestricted subsidiaries. These covenants are subject to a number of important exceptions and qualifications. 2016 Credit Agreement due 2027 On February 16, 2016 , we entered into the 2016 Credit Agreement. From 2016 to 2022, we entered into various amendments to the 2016 Credit Agreement, including the amendment in October 2022, as described below. On October 13, 2022, the Company entered into an amendment of the 2016 Credit Agreement (the “Fifth Amendment”). The Fifth Amendment provides for, among other things, a new five-year revolving credit facility in an aggregate principal amount of $ 250.0 million (the “New Revolving Credit Facility”). The New Revolving Credit Facility refinances and replaces the previously existing $ 80.0 million revolving credit facility under the 2016 Credit Agreement. The Company’s obligations under the 2016 Credit Agreement continue to be secured by substantially all of its and its direct and indirect subsidiaries’ assets, and is senior in position to the 2021 Senior Notes due 2029. Contemporaneously with the Fifth Amendment, the Company drew down $ 160.0 million of funds available under the New Revolving Credit Facility. Proceeds totaling $ 61.6 million from the $ 160.0 million drawdown were used to repay then existing term loan borrowings under the 2016 Credit Agreement totaling $ 60.0 million, plus accrued interest and fees totaling $ 1.6 million. As discussed below, the remaining $ 98.4 million of proceeds were used to fund the cash portion of the Martin Acquisition. The Company made repayments of borrowings under the New Revolving Credit Facility totaling $ 83.6 million through December 31, 2022. Interest on borrowings under the New Revolving Credit Facility is payable either quarterly or at the expiration of any Secured Overnight Financing Rate ("SOFR") interest period applicable thereto. Borrowings under the New Revolving Credit Facility accrue interest at a rate equal to, at our option, a base rate (with a floor of 100 basis points) plus a percentage spread (ranging from 0.75 % to 1.75 %) based on our first lien net leverage ratio or SOFR (with a floor of 0 basis points) plus a percentage spread (ranging from 1.75 % to 2.75 %) based on our first lien net leverage ratio. After giving effect to the Fifth Amendment, we will pay quarterly commitment fee on the unused portion of the New Revolving Credit Facility equal to a percentage spread (ranging from 0.25 % to 0.35 %) based on our first lien net leverage ratio. The Fifth Amendment also modifies the application of the financial covenant under the 2016 Credit Agreement such that testing will occur on a quarterly basis, commencing with the fiscal quarter ending December 31, 2022. As of December 31, 2022, borrowings outstanding under the $ 250.0 million New Revolving Credit Facility totaled $ 76.4 million, and accrued interest was $ 235 thousand. There were $ 5.7 million in letters of credit outstanding. Availability under the New Revolving Credit Facility at December 31, 2022 totaled $ 167.9 million. The weighted average all-in interest rate for borrowings under the existing revolving credit facility of the 2016 Credit Agreement due 2027 was 6.07 % as of December 31, 2022, and for borrowings under the term loan facility of the then existing 2016 Credit Agreement due 2024 was 2.10 % at January 1, 2022. The Martin Acquisition was financed in past with the $ 250.0 million available under the New Revolving Credit Facility provided by the Fifth Amendment of our 2016 Credit Agreement, under which we drew $ 160.0 million on October 14, 2022, the proceeds of which were used to pay $ 98.4 million of the $ 187.8 million total fair value of consideration transferred, and $ 61.6 million to prepay our $ 60.0 million existing term loans under the Fourth Amendment of our 2016 Credit Agreement, plus $ 1.6 million in fees, costs and accrued interest. The remainder of the total fair value of consideration transferred totaling $ 89.4 million was funded with cash on hand previously generated through operations. We also paid buyer fees and costs relating to the Martin Acquisition totaling $ 4.8 million in the year ended December 31, 2022, classified as selling, general and administrative expenses in the accompanying consolidated statements of operations for the year ended December 31, 2022.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	10. Derivatives Aluminum Contracts and Midwest Transaction Premium We enter into aluminum forward contracts to hedge the fluctuations in the purchase price of aluminum extrusion we use in production. We also enter into forward contracts to hedge the fluctuations in the price of the delivery component of our aluminum extrusion purchases, known as the Midwest Transaction Premium, or MTP. Our contracts are designated as cash flow hedges since they are highly effective in offsetting changes in the cash flows attributable to forecasted purchases of aluminum and the related MTP. We record our aluminum hedge contracts at fair value, based on trading values for aluminum forward contracts. Aluminum forward contracts identical to those held by us trade on the London Metal Exchange (“LME”). The LME provides a transparent forum and is the world’s largest center for the trading of futures contracts for non-ferrous metals. The prices are used by the metals industry worldwide as the basis for contracts for the movement of physical material throughout the production cycle. Based on this high degree of volume and liquidity in the LME, we believe the valuation price at any measurement date for contracts with identical terms as to prompt date, trade date and trade price as those we hold at any time represents a contract’s exit price to be used for purposes of determining fair value. We record our MTP hedge contracts at fair value, based on the Platts MW US Transaction price per pound assessment, which has been a benchmark for decades in the North American aluminum industry. Platts surveys the North American market daily to capture trades, bids and offers on a delivered Midwest basis. Data is normalized to reflect the typical price per pound between the largest number of market participants, for delivery within 7 to 30 days from date of publication, net- 30 -day payment terms, for typical order quantities, chemistries and freight allowances. The survey is extensive and encompasses both domestic and offshore producers, traders and brokers that are varied in scope. Based on the extensive nature of this pricing mechanism, we believe the Platts MW US Transaction price at any time represents a contract’s exit price to be used for purposes of determining fair value. Guidance under the Financial Instruments Topic 825 of the Codification requires us to record our hedge contracts at fair value and consider our credit risk for contracts in a liability position, and our counter-party’s credit risk for contracts in an asset position, in determining fair value. We assess our counter-party’s risk of non-performance when measuring the fair value of financial instruments in an asset position by evaluating their financial position, including cash on hand, as well as their credit ratings. We assess our risk of non-performance when measuring the fair value of our financial instruments in a liability position by evaluating our credit ratings, our current liquidity including cash on hand and availability under our New Revolving Credit Facility as compared to the maturities of the financial liabilities. Management makes an accounting policy election not to offset the estimated fair value amounts recognized for derivatives executed with the same counterparty under the same master netting arrangement. Our counterparties to our derivative contracts do not require the Company to post collateral against hedge contracts in a liability position, if any. At December 31, 2022, we had no outstanding aluminum forward contracts. At December 31, 2022, the fair value of our MTP hedge contracts was in an asset position of $ 0.3 million. We had one outstanding MTP contract to hedge the Platt US MW Transaction price per pound for the delivery of 7.5 million pounds of aluminum through December 2023, at an average price of $ 0.21 per pound, with a maturity date in twelve months . We assessed the risk of non-performance of the Company and our counterparty, as applicable, and determined it was immaterial and, therefore, did not record any adjustment to the fair value as of December 31, 2022. We assess the effectiveness of our cash flow hedges by comparing the change in the fair value of the forward contract to the change in the expected cash to be paid for the hedged item. The gain or loss on our hedging contracts is reported as a component of accumulated other comprehensive income (loss) and is reclassified into earnings in the same line item in the income statement as the hedged item in the same period or periods during which the transaction affects earnings. The amount of income, net, recognized in the “accumulated other comprehensive income (loss)” line item in the accompanying consolidated balance sheet as of December 31, 2022, that we expect will be reclassified to earnings within the next twelve months, is $ 0.3 million.

Fair Value Disclosures [Abstract]
Fair Value	11. Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A three-tier fair value hierarchy is used to prioritize the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The three levels of the fair value hierarchy are as follows: Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. The accounting guidance concerning fair value allows us to elect to measure financial instruments at fair value and report the changes in fair value through earnings. This election can only be made at certain specified dates and is irrevocable once made. We do not have a policy regarding specific assets or liabilities to elect to measure at fair value, but rather we make the election on an instrument-by-instrument basis as they are acquired or incurred. During 2022, 2021, or 2020, we did no t make any transfers between Level 1, Level 2 or Level 3 financial assets. We conduct reviews on a quarterly basis to verify pricing, assess liquidity, and determine if significant inputs have changed that would impact the fair value hierarchy disclosure. Fair Value of Financial Instruments Our financial instruments include cash equivalents, accounts and notes receivable, accounts payable, and accrued liabilities, whose carrying amounts approximate their fair values due to their short-term nature. Our financial instruments also include borrowings under our 2016 Credit Agreement due 2027, as well as the 2021 Senior Notes due 2029 at December 31, 2022 and January 1, 2022, all classified as long-term debt. The fair value of borrowings under the 2016 Credit Agreement due 2027 approximates its carrying value due to its variable interest rate nature, and was approximately $ 76.4 million as of December 31, 2022, compared to a principal outstanding value of $ 76.4 million, and $ 60.0 million as of January 1, 2022, compared to a principal outstanding value of $ 60.0 million. The fair value of the 2021 Senior Notes due 2029 is also based on debt with similar terms and characteristics and was approximately $ 480.8 million as of December 31, 2022, compared to a principal outstanding value of $ 575.0 million, and $ 578.2 million as of January 1, 2022, compared to a principal outstanding value of $ 575.0 million. Fair values were determined based on observed trading prices of our debt between domestic financial institutions, which we consider to be Level 2 inputs. The carrying amounts for financial instruments measured at fair value are as follows: Fair Value Measurements Assets (Liabilities) Quoted Significant Prices in Other Significant Active Observable Unobservable Markets Inputs Inputs December 31, 2022 Total (Level 1) (Level 2) (Level 3) Description Aluminum forward contracts $ — $ — $ — $ — MTP contracts 300 — 300 — $ 300 $ — $ 300 $ — January 1, 2022 Total (Level 1) (Level 2) (Level 3) Description Aluminum forward contracts, net $ 4,829 $ — $ 4,829 $ — MTP contracts, net 4,599 — 4,599 — $ 9,428 $ — $ 9,428 $ —

The unamortized amount of this goodwill for tax purposes, including the goodwill as a result of the Anlin Acquisition discussed below, was $ 169.4 million and $ 185.7 million at December 31, 2022, and January 1, 2022, respectively. These amounts exclude the tax basis of goodwill of Eco, which we may benefit from based on our 75 % ownership stake in Eco Enterprises LLC. For tax purposes, contingent consideration does not become part of tax goodwill until paid. As such, the amount of goodwill deductible for tax purposes in the Anlin Acquisition will not be finalized until the payment of the contingent consideration for 2022 is paid. As of December 31, 2022, the estimated fair value of the contingent consideration in the allocation relating to this remaining payment was $ 4.3 million, and goodwill according to the current allocation of consideration is $ 9.6 million. As such, as of December 31, 2022, the amount of goodwill estimated to be tax deductible is the difference of $ 5.3 million. See Note 5 for further discussion of the contingent consideration in the Anlin Acquisition. In the Martin Acquisition, we acquired goodwill totaling $ 90.3 million. Because the Martin Acquisition was structured as an acquisition of the stock of a C corporation, a step-up election is not available. Therefore, we do not believe any of the goodwill as a result of the Martin Acquisition is deductible for tax purposes. Excess Tax Benefits Excess tax benefits resulting from the exercise of stock options and lapse of restriction on stock awards are recognized as a component of tax expense. Income tax expense in the years ended December 31, 2022, January 1, 2022, and January 2, 2021, includes excess tax benefits totaling $ 0.2 million, $ 0.9 million, and $ 0.8 million, respectively. Income Taxes Payable Accrued liabilities on December 31, 2022 includes income taxes currently payable of $ 16.4 million. Other current assets on January 1, 2022 included income taxes receivable of $ 6.7 million. Open Tax Years The tax years 2014 to 2021 remain open for examination by the IRS and Florida due to the statute of limitations and net operating losses utilized in prior tax years.

Legal Proceedings We are a party to various legal proceedings in the ordinary course of business. Although the ultimate disposition of those proceedings cannot be predicted with certainty, management believes the outcome of any claim that is pending or threatened, either individually or on a combined basis, will not have a materially adverse effect on our operations, financial position or cash flows.

Equity [Abstract]
Shareholders' Equity	16. Shareholders’ Equity 2019 Share Repurchase Program On May 22, 2019, our Board of Directors authorized and approved a share repurchase program of up to $ 30.0 million. The repurchases may be made in open-market or private transactions from time to time. Repurchases of shares may be made under a Rule 10b5-1 plan, which would permit repurchases when the Company might otherwise be precluded from doing so under applicable laws. The Company bases repurchase decisions, including the timing of repurchases, on factors such as the Company’s stock price, general economic and market conditions, the potential impact on the Company’s capital structure, the expected return on competing uses of capital such as strategic acquisitions and capital investments, and other corporate considerations, as determined by management. From the inception of the program on May 22, 2019, through January 2, 2021, we made repurchases of 393,819 shares of our common stock at a total cost of $ 5.5 million under this program. We made no repurchases under this program during 2020 or 2021. During the fourth quarter of 2022, we made repurchases of 86,124 shares of our common stock at a total cost of $ 1.6 million under this program. The repurchase program may be suspended or discontinued at any time. Repurchases of Company Common Stock In addition to the repurchases of our common stock in the open market during 2022 discussed above, during 2022 and 2021, we repurchased 95,001 shares and 73,105 shares, respectively, of our common stock at a total cost of $ 1.9 million and $ 1.6 million, respectively, all relating to purchases from employees to satisfy tax withholding obligations in connection with the vesting of restricted stock awards. Those shares were immediately retired. 2021 Equity Issuance in Eco Acquisition On February 1, 2021 , we completed the Eco Acquisition, which represented a 75 % stake in the newly created entity Eco Enterprises. The fair value consideration we transferred for Eco was $ 102.0 million, including $ 94.4 million in cash and $ 1.5 million in fair value of contingent consideration. The fair value of consideration also included PGT Innovations, Inc. common stock with a then estimated fair value of $ 6.1 million. The common stock portion of the purchase price was represented by the issuance of 357,797 shares of PGT Innovations, Inc. common stock on February 1, 2021, with a closing price value of $ 21.34 per share on that date, or approximately $ 7.6 million based on that price. However, the seller of Eco, who is also the holder of the 25 % redeemable non-controlling interest in Eco Enterprises, is restricted from selling these shares for a three-year period from the date of the acquisition. As such, we estimated that there was an approximately 20 % discount for the lack of marketability of the shares.

Share-Based Payment Arrangement [Abstract]
Stock Based Compensation	17. Stock-Based Compensation 2019 Equity Plan On May 22, 2019, our shareholders approved, and we adopted the 2019 Equity and Incentive Compensation Plan (the “2019 Equity Plan”) whereby equity-based awards of up to a total of 1,550,000 shares may be granted by the Board to eligible non-employee directors, selected officers and other employees, advisors and consultants of ours. A summary of certain key features and terms of the 2019 Equity Plan is set forth below. A more complete discussion about the 2019 Equity Plan is set forth in the Company’s proxy statement for its 2019 annual meeting of stockholders, which was filed with the SEC on April 23, 2019. On June 10, 2022, our shareholders approved, and we adopted, the Amended and Restated 2019 Equity and Incentive Compensation Plan (the "Amended and Restated 2019 Equity Plan") which, among other things, increase the total number of shares of common stock available for grant by 3,000,000 shares. A more complete discussion about the 2019 Equity Plan is set forth in the Company’s proxy statement for its 2019 annual meeting of stockholders, which was filed with the SEC on June April 29, 2022. Amended and Restated 2019 Equity and Incentive Compensation Plan • sets forth the total number of shares of common stock available for grant thereunder, at 4,550,000 shares, • sets forth the types of awards eligible under the plan, including issuances of options, share appreciation rights, restricted shares, restricted share units, share bonuses, other share-based awards and cash awards, and • sets forth the maximum number of shares that may be made subject to awards in any calendar year to any “covered employee” (within the meaning of Section 162(m) of the Internal Revenue Code). • shares previously granted under predecessor plans, including the 2014 Equity Plan and the 2006 Equity Plan, may be available for issuance under the 2019 Equity Plan under certain circumstances described below. There were 3,066,540 shares available for grant under the Amended and Restated 2019 Equity Plan at December 31, 2022. Recent Issuances On February 14, 2022, we issued 468,518 shares of restricted stock to certain executive and non-executive employees of the Company, under the Company’s 2022 long-term incentive plan (“2022 LTIP”). The final number of half of the shares awarded under the 2022 LTIP, or 234,259 shares, is subject to adjustment based on the performance of the Company for the 2022 fiscal year and was not final as of December 31, 2022. Additionally, a portion of the 234,259 performance shares issued under the 2022 LTIP are subject to a total shareholder return ("TSR") component, which will not be finalized until the third anniversary of the February 14, 2022 grant date. Specifically, 37.5 % of the one-half of the restricted stock awarded in the 2022 LTIP are performance restricted shares which will not be earned unless certain financial performance metrics are met by the Company for the 2022 fiscal year. The performance criteria, as defined in the share awards, provide for a graded awarding of shares based on the percentage by which the Company meets earnings before interest, taxes, depreciation and amortization ("EBITDA") as defined in our 2022 business plan. The percentages, ranging from less than 80 % to greater than or equal to 120 % of the target amount of that EBITDA metric, provide for the awarding of shares ranging from 0 % to 200 % of the target amount of shares with respect to 37.5 % of half of the 468,518 shares, or 87,847 shares. The remaining 62.5 % of the one-half of the restricted stock awarded in the 2022 LTIP, or 146,412 shares, are subject to the same EBITDA metric, but are also subject to a TSR component which stratifies the performance of the Company's common stock price compared to a defined peer group of companies over the three-year period subsequent to February 14, 2022, such that if the Company's TSR falls at the 75th percentile or higher compared to the peer group, grantees will receive an additional 25 % of performance shares. If the Company's TSR falls at the 25th percentile or lower compared to the peer group, grantees will forfeit 25 % of performance shares. If the Company's TSR falls within the 75th and 25th percentiles, there will be no additional adjustment and grantees will receive their performance shares as per the EBITDA metric previously discussed. The final award is also affected by forfeitures upon the termination of a grantee’s employment with the Company. The remaining 234,259 shares from the 2022 LTIP are not subject to adjustment based on any performance or other criteria, but rather, vest in three equal installments on each of the first, second and third anniversaries of the grant date, assuming the grantee is employed by the Company on those vesting dates. The grant date fair value of the 2021 LTIP was $ 18.27 per share for those shares not subject to adjustment based on any performance or other criteria except the passage of time, and the 37.5 % of shares subject only to the EBITDA criteria of Company performance. For the 62.5 % of performance shares subject to both the EBITDA criteria of Company performance and the TSR component, the grant date fair value was $ 20.79 per share as determined by a third-party valuation specialist engaged by the Company, which used Monte Carlo simulation techniques to determine the fair value of such shares, which we consider to be a Level 3 input. On June 10, 2022, we issued a total of 35,588 shares of restricted stock awards to seven non-employee board members of the Company, and 10,168 restricted stock units to two non-employee board members of the Company who elected to defer receipt of their stock awards, as the non-cash portion of their annual compensation for participation on the Company’s Board of Directors. The restrictions on these awards lapse one year after the grant date. The awards have a weighted average fair value on date of grant of $ 19.67 based on the New York Stock Exchange market price of the common stock. We record stock compensation expense over an equity award’s vesting period using the award’s fair value at the date of grant. We recorded compensation expense for stock-based awards of $ 9.7 million, $ 7.8 million and $ 5.5 million for the years ended December 31, 2022, January 1, 2022, and January 2, 2021, respectively. Of the $ 9.7 million, $ 7.8 million and $ 5.5 million in stock-based compensation expense in the years ended December 31, 2022, January 1, 2022, and January 2, 2021, respectively, $ 8.2 million, $ 6.4 million and $ 4.8 million, respectively, are classified within selling, general and administrative expense in the accompanying consolidated statements of operations for those years, with the remainder classified within cost of sales. Restricted Share Awards A summary of the status of restricted share awards as of December 31, 2022, and changes during the year then ended, are presented below: Number of Weighted Outstanding at January 1, 2022 1,146,106 $ 18.25 Granted 566,906 $ 19.15 Vested ( 359,360 ) $ 19.83 Forfeited/Performance adjustment ( 85,394 ) $ 20.82 Outstanding at December 31, 2022 1,268,258 $ 18.75 As of December 31, 2022, the remaining compensation cost related to non-vested share awards was $ 9.6 million which is expected to be recognized in earnings using an accelerated method resulting in higher levels of compensation costs occurring in earlier periods over a weighted average period of 1.6 years.

Redeemable Non-Controlling Interest	20. Redeemable Non-Controlling Interest On February 1, 2021, we completed an acquisition of a 75 % ownership stake in Eco. The seller of Eco obtained the remaining equity interest in the newly formed company, Eco Enterprises. The seller’s redeemable non-controlling interest was initially established at fair value. The agreement between PGT Innovations, Inc. and the seller provides the Company with a call right for seller’s equity interest in the third year following the acquisition date. If the Company does not exercise its right to call by the third anniversary, the agreement provides the seller with a put right which can be exercised during the 15-day period following the third anniversary. Upon exercise of the put or call right, the purchase price is calculated based on a future agreed performance metric. The put option makes the non-controlling interest redeemable and, therefore, the redeemable non-controlling interest is classified as temporary equity outside of shareholders’ equity. The Company calculates the estimated future redemption value of the non-controlling interest on a quarterly basis and is adjusted to accreted value using the effective interest method. Any accretion adjustment in the current reporting period of the redeemable non-controlling interest is offset against retained earnings and impacts earnings used in the calculation of earnings per share attributable to common shareholders in the reporting period. Based on the formula in the operating agreement governing this transaction, the future redemption value of the redeemable non-controlling interest was estimated to be $ 37.3 million, which we accreted to $ 34.7 million as of December 31, 2022. The following table presents the changes in the Company’s redeemable non-controlling interest for the period presented: Year Ended December 31, January 1, (in thousands) 2022 2022 Balance at beginning of year $ 36,863 $ — Redeemable non-controlling interest in Eco at initially estimated fair value — 28,464 Net income attributable to redeemable non-controlling interest 1,523 2,318 Change in value of redeemable non-controlling interest ( 2,000 ) 6,081 Distribution to non-controlling interest ( 1,665 ) — Balance at end of year $ 34,721 $ 36,863

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”).
Fiscal period	Fiscal period Our fiscal year consists of 52 or 53 weeks ending on the Saturday nearest December 31 of the related year. The years ended December 31, 2022, and January 1, 2022, consisted of 52 weeks. The year ended January 2, 2021 consisted of 53 weeks.
Principles of consolidation	Principles of consolidation The consolidated financial statements present the results of the operations, financial position and cash flows of PGTI, and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. We are consolidating all wholly owned subsidiaries, as well as Eco, based on the 75 % majority ownership. We refer to Note 20 for our accounting policies relating to the non-redeemable minority interest.
Segment information	Segment information We operate as two segments based on geography: the Southeast segment and the Western segment. See Note 19 for more information.
Use of estimates	Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates.
Revenue recognition	Revenue recognition Revenue is recognized when our performance obligations are satisfied. Generally, our performance obligations are satisfied over time when control of our products is transferred, and revenue is recognized at a single point in time, when title transfers to our customer for product shipped or when services are provided. Revenues are recorded net of any sales incentives. See Note 4, “Revenue Recognition and Contracts with Customers.”
Cost of sales	Cost of sales Cost of sales represents costs directly related to the production of our products. Primary costs include raw materials, direct labor, and manufacturing overhead, which consist of salaries, wages, employee benefits, utilities, maintenance, lease costs and depreciation.
Shipping and handling costs	Shipping and handling costs Shipping and handling costs incurred in the purchase of materials used in the manufacturing process are included in cost of sales. Costs relating to shipping, handling and distribution of finished products to our customers are included in selling, general and administrative expenses and totaled $ 75.1 million, $ 62.4 million and $ 39.3 million for the years ended December 31, 2022, January 1, 2022, and January 2, 2021, respectively.
Advertising	Advertising We expense advertising costs as incurred. Advertising expense, which is included in selling, general and administrative expenses, was $ 22.7 million, $ 15.8 million and $ 11.6 million for the years ended December 31, 2022, January 1, 2022 and January 2, 2021, respectively. NewSouth, acquired on February 1, 2020, relies heavily on advertising, consistent with its sales-direct-to-homeowner business model.
Cash and cash equivalents	Cash and cash equivalents Cash and cash equivalents consist of cash on hand or highly liquid investments with an original maturity date of three months or less when purchased.
Accounts receivable, net	Accounts receivable, net In the ordinary course of business, we extend credit to qualified dealers and distributors, generally on a non-collateralized basis. The Company maintains an allowance for credit losses which is based on management’s assessments of the amount which may become uncollectible in the future and is determined through consideration of our write-off history, specific identification of uncollectible accounts based in part on the customer’s past due balance (based on contractual terms), and consideration of prevailing economic and industry conditions. Uncollectible accounts are written off after repeated attempts to collect from the customer have been unsuccessful. December 31, January 1, 2022 2022 (in thousands) Accounts receivable $ 173,763 $ 145,923 Less: Allowance for credit losses ( 13,656 ) ( 4,702 ) Accounts receivable, net $ 160,107 $ 141,221
Self-insurance reserves	Self-insurance reserves We are primarily self-insured for employee health benefits and workers’ compensation claims prior to 2010 and after 2017. Provisions for losses under these programs are recorded based on the Company’s estimates of the aggregate liabilities for the claims incurred. Accruals for healthcare claims and workers’ compensation are included in accrued liabilities in the accompanying consolidated balance sheets.
Warranty expense	Warranty expense We have warranty obligations with respect to most of our manufactured products. Warranty periods, which vary by product components, generally range from 1 to 10 years , although the warranty period for a limited number of specifically identified components in certain applications is a lifetime. However, the majority of the products sold have warranties on components which range from 1 to 3 years . The Company has recorded a reserve for estimated warranty and related costs based on historical experience and periodically adjusts these provisions to reflect actual experience. During 2022, we recorded warranty expense at an average rate of 2.1 % of sales. This rate approximates the average rate of 2.0 % of sales recorded in 2021. The average rate of 2.0 % of sales in 2021 compares to an average rate of 1.7 % of sales recorded in 2020. The increase in our warranty expense rate in 2021, compared to 2020 was a result of costs associated with higher levels of warranty repair experience on larger commercial projects than experienced in 2020, which resulted in warranty costs incremental to those we would incur in the normal course of business. The increase in our warranty expense in 2021, compared to 2020, was also affected by costs associated with the wind-down of the commercial business of NewSouth in the first quarter of 2021, which resulted in warranty costs incremental to those we would incur in the normal course of business. We assess the adequacy of our warranty accrual on a quarterly basis, and adjust the previous amounts recorded, if necessary, to reflect the change in estimate of the future costs of claims yet to be serviced. The following provides information with respect to our warranty accrual. Accrued Warranty Beginning of Acquired (Acquisition Charged to Adjustments Settlements End of (in thousands) Year ended December 31, 2022 $ 13,504 $ ( 2,537 ) $ 31,223 $ 698 $ ( 27,500 ) $ 15,388 Year ended January 1, 2022 $ 8,001 $ 4,150 $ 23,637 $ ( 1,440 ) $ ( 20,844 ) $ 13,504 Year ended January 2, 2021 $ 6,244 $ 3,515 $ 15,256 $ 266 $ ( 17,280 ) $ 8,001 During the third quarter of 2022, we finalized our calculation of the reserve for warranty obligations assumed in the Anlin Acquisition. As a result, we recorded an acquisition adjustment to decrease Anlin's warranty reserve by $ 2.5 million from its initial estimate in our then preliminary allocation of the fair value of assets acquired and liabilities assumed, resulting in an equal decrease in goodwill. The accrual for warranty is included in accrued liabilities and other liabilities, depending on estimated settlement date, in the consolidated balance sheets as of December 31, 2022 and January 1, 2022. The portion of warranty expense related to the issuance of product of $ 3.9 million, $ 3.0 million and $ 3.8 million is included in cost of sales in the consolidated statements of operations for the years ended December 31, 2022, January 1, 2022, and January 2, 2021, respectively. The portion related to servicing warranty claims including costs of the service department personnel is included in selling, general and administrative expenses in the consolidated statements of operations, and is $ 28.1 million, $ 19.2 million and $ 11.7 million, respectively, for the years ended December 31, 2022, January 1, 2022, and January 2, 2021.
Inventories	Inventories Inventories consist principally of raw materials purchased for the manufacture of our products. We have limited work-in-progress and finished goods inventory as most products are custom, made-to-order products manufactured under noncancelable purchase orders and therefore are recognized as costs of sales relating to revenue recognized over time during the manufacturing process. All inventories are stated at the lower of cost (first-in, first-out method) or net realizable value. The reserve for obsolescence, which was immaterial at December 31, 2022 and January 1, 2022, is based on management’s assessment of the amount of inventory that may become obsolete in the future and is determined through Company history, specific identification and consideration of prevailing economic and industry conditions. Inventories consist of the following: December 31, January 1, 2022 2022 (in thousands) Raw materials $ 109,679 $ 87,164 Work in progress 916 3,248 Finished goods 2,077 1,028 Inventories $ 112,672 $ 91,440
Property, plant and equipment	Property, plant and equipment Property, plant and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. Depreciable assets are assigned estimated lives as follows: Building and improvements 5 to 40 years Leasehold improvements Shorter of lease term or estimated useful life Furniture and equipment 3 to 10 years Vehicles 5 to 10 years Computer software 3 years Maintenance and repair expenditures are charged to expense as incurred.
Leases	Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets, current portion of operating lease liability, and operating lease liability, less current portion, on our consolidated balance sheets. The Company currently does not have any finance leases. Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease right-of-use asset also includes any up-front lease payments made and initial direct costs incurred, less lease incentives received. Our lease terms may include options to extend or terminate the lease. Lease expense is recognized on a straight-line basis over the lease term. We elected the practical expedient to not separate lease and non-lease components for all classes of underlying assets.
Long-lived assets	Long-lived assets We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of long-lived assets to future undiscounted net cash flows expected to be generated . If such assets are considered to be impaired, the impairment recognized is the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell, and depreciation is no longer recorded.
Computer software	Computer software We capitalize costs associated with software developed or obtained for internal use when both the preliminary project stage is complete, and it is probable that computer software being developed will be completed and placed in service. Capitalized costs include: (i) external direct costs of materials and services consumed in developing or obtaining computer software, (ii) payroll and other related costs for employees who are directly associated with and who devote time to the software project, and (iii) interest costs incurred, when material, while developing internal-use software. Capitalization of such costs ceases no later than the point at which the project is substantially complete and ready for its intended purpose. Capitalized software as of December 31, 2022, and January 1, 2022, was $ 31.7 million and $ 31.8 million, respectively. Accumulated depreciation of capitalized software was $ 30.3 million and $ 29.0 million as of December 31, 2022, and January 1, 2022, respectively. Amortization expense for capitalized software was $ 3.0 million, $ 3.7 million, and $ 4.1 million for the years ended December 31, 2022, January 1, 2022, and January 2, 2021, respectively. We review the carrying value of capitalized software and development costs for impairment in accordance with our policy pertaining to the impairment of long-lived assets.
Goodwill	Goodwill Goodwill is calculated as the excess of the consideration paid in a business combination over the fair value of the identifiable net assets acquired. We test goodwill for impairment at the reporting unit level at least annually or whenever events or circumstances indicate that the carrying value of goodwill may not be recoverable. Our annual test for impairment is done on the first date of our fiscal fourth quarter. We consider various qualitative factors, including macroeconomic and industry conditions, financial performance of the Company and changes in the stock price of the Company to determine whether it is necessary to perform a quantitative test for goodwill impairment. If we believe, as a result of our qualitative assessment, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Under the quantitative test, goodwill is tested under a one-step method for impairment at a level of reporting referred to as a reporting unit. This quantitative analysis involves identifying potential impairment by comparing the fair value of each reporting unit with its carrying amount and, if the carrying amount of a reporting unit exceeds its fair value, then a charge for goodwill impairment will be recognized in the amount by which a reporting unit’s carrying value exceeds its fair value. For our Southeast and Western reporting units, based on qualitative assessments, we concluded that quantitative assessments were not required to be performed. See Note 7 for further discussion of the goodwill of our reporting units.
Trade names	Trade names The Company has indefinite-lived intangible assets in the form of certain trade names. The impairment evaluation of the carrying amount of our indefinite-lived trade names is conducted annually, or more frequently, if events or changes in circumstances indicate that they might be impaired. We have the option of performing a qualitative assessment of impairment to determine whether any further quantitative testing for impairment is necessary. If we elect to bypass the qualitative assessment or if we determine, based on qualitative factors, that it is more likely than not that the fair value of our indefinite-lived trade names is less than the carrying amount, an evaluation is performed by comparing their carrying amount to their estimated fair values. If the estimated fair value is less than the carrying amount of the indefinite-lived trade name, then an impairment charge is recorded to reduce the carrying value to its estimated fair value. The estimated fair value is determined using the relief from royalty method that is based upon the discounted projected cost savings (value) attributable to ownership of our trade names, our only indefinite-lived intangible assets. Other than the WinDoor trade name, based on qualitative assessments for 2022, the Company concluded it was more likely than not the fair value of the indefinite-lived intangible assets exceeded their carrying values. For the WinDoor trade name, we concluded that a quantitative assessment was required, given the recent decrease in sales of the brand and given the narrow excess of the fair value over the carrying value of our WinDoor trade name in our prior quantitative assessment, which resulted in an impairment charge of $ 7.4 million in the year ended December 31, 2022. We review the carrying value of our finite-lived trade name in accordance with our policy for long-lived assets. See Note 7 for further discussion of our trade name.
Derivative financial instruments	Derivative financial instruments We utilize certain derivative instruments, from time to time, including forward contracts to manage variability in cash flow associated with commodity market price risk exposure in the aluminum market. We do not enter into derivatives for speculative purposes.
Concentrations of credit risk	Concentrations of credit risk Financial instruments, which potentially subject us to concentrations of credit risk, consist principally of cash and cash equivalents, trade accounts receivable and contract assets. Accounts receivable and contract assets are due primarily from dealers and distributors of building materials, and other companies in the construction industry, primarily located in Florida, California, Texas, Arizona and, with the Martin Acquisition in October 2022, Utah. Credit is extended based on an evaluation of the customer’s financial condition and credit history, and generally collateral is not required. The Company maintains an allowance for potential credit losses on trade receivables and contract assets. We maintain our cash with several financial institutions, the balance of which exceeds federally insured limits. At December 31, 2022 and January 1, 2022, our cash balance exceeded the insured limit by $ 61.4 million and $ 89.0 million, respectively.
Comprehensive income (loss)	Comprehensive income (loss) The Company reports comprehensive income (loss), defined as the total of net income and other comprehensive income (loss), which is composed of all other non-owner changes in equity, and the components thereof, in its consolidated statements of comprehensive income. The components of other comprehensive income (loss) relate to gains and losses on cash flow hedges. Reclassification adjustments reflecting such gains and losses are recorded as income in the same period as the hedged items affect earnings.
Stock-based compensation	Stock-based compensation We use a fair-value based approach for measuring stock-based compensation and record compensation expense over an award’s vesting period based on the award’s fair value at the date of grant. Our Company’s awards vest based on service conditions and certain performance conditions and compensation expense is recognized generally on a straight-line basis for each separately vesting portion of an award. Stock-based compensation expense is recognized only for those awards that ultimately vest.
Income and Sales Taxes	Income and Sales Taxes We account for income taxes utilizing the liability method. Deferred income taxes are recorded to reflect consequences on future years of differences between financial reporting and the tax basis of assets and liabilities measured using the enacted statutory tax rates and tax laws applicable to the periods in which differences are expected to affect taxable earnings. We have no liability for unrecognized tax benefits. However, should we accrue for such liabilities, when and if they arise in the future, we will recognize interest and penalties associated with uncertain tax positions as part of our income tax provision. Income taxes relating to gains and losses on our cash flow hedges are released at the same time as the underlying transactions are realized. Interest and penalties on income taxes, if any, are recorded as income taxes. Refer to Note 12 for additional information regarding the Company’s income taxes. Sales taxes collected from customers have been recorded on a net basis.
Net income per common share	Net income per common share Basic earnings per share (“EPS”) available to PGT Innovations, Inc. common stockholders is computed using the two-class method by dividing net income attributable to common shareholders, after deducting the redemption adjustment related to the redeemable noncontrolling interest, by the average number of common shares outstanding during the period. Diluted EPS available to PGT Innovations, Inc. common stockholders is computed using the two-class method by dividing net income attributable to common shareholders, after deducting the redemption adjustment related to the redeemable noncontrolling interest, by the average number of common shares outstanding, including the dilutive effect of common stock equivalents computed using the treasury stock method and the average share price during the period. Forfeiture of unvested equity are recognized on an actual basis, at the same time as the equity is forfeited. There were no anti-dilutive shares outstanding for the years ended December 31, 2022 and January 1, 2022. Our weighted average number of diluted shares outstanding excludes underlying securities of 23 thousand for the year ended January 2, 2021, because their effects were anti-dilutive. The table below presents the calculation of basic and diluted earnings per share, including a reconciliation of weighted average common shares: Year Ended December 31, January 1, January 2, 2022 2022 2021 (in thousands, except per share amounts) Net income $ 98,405 $ 35,196 $ 45,108 Less: Net income attributable to redeemable non-controlling interest ( 1,523 ) ( 2,318 ) — Net income attributable to the Company 96,882 32,878 45,108 Change in redemption value of redeemable non-controlling interest 2,000 ( 6,081 ) — Net income attributable to common shareholders $ 98,882 $ 26,797 $ 45,108 Weighted-average common shares - Basic 59,926 59,518 58,887 Add: Dilutive shares from equity plans 393 540 473 Weighted-average common shares - Diluted 60,319 60,058 59,360 Weighted average number of common shares outstanding: Basic $ 1.65 $ 0.45 $ 0.77 Diluted $ 1.64 $ 0.45 $ 0.76
Supplemental cash flow information and non-cash activity	Supplemental cash flow information and non-cash activity The table below presents supplemental cash flow information and non-cash activity for the years ended December 31, 2022, January 1, 2022, and January 2, 2021: Year Ended December 31, January 1, January 2, (in thousands) 2022 2022 2021 Supplemental cash flow information: Interest paid $ 27,948 $ 32,636 $ 25,156 Income tax payments, net of refunds $ 21,499 $ 12,166 $ 9,242 Non-cash activity: Establish right-of-use asset $ 29,031 $ 65,678 $ 19,185 Establish operating lease liability $ ( 29,031 ) $ ( 65,678 ) $ ( 19,185 ) Reclassification of accounts receivable to notes receivable $ 4,225 $ — $ 1,437 Property, plant and equipment additions in accounts payable $ 565 $ 772 $ 61
Accounting Pronouncements Recently Adopted	Accounting Pronouncements Recently Adopted Business Combinations - Contracts Assets and Liabilities On October 28, 2021, the FASB issued ASU 2021-08,1 which amends ASC 805-20 to “require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination.” Under current GAAP, an acquirer generally recognizes such items at fair value on the acquisition date. This standard was effective beginning December 31, 2022 . Early adoption was permitted. The Company adopted this standard for the year ended January 1, 2022. The adoption of this standard did not have any impact on our consolidated financial statements. Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” and in January 2021, subsequent amendment to the initial guidance, ASU 2021-01, “Reference Rate Reform (Topic 848): Scope” (collectively, “Topic 848”). In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848,” which defers its sunset date to June 2023 as a result of the UK Financial Conduct Authority's extension of the LIBOR cessation date to June 30, 2023. Topic 848 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The guidance generally can be applied currently, through June 30, 2023. Topic 848 has had and will have no impact on the reference rates in our financing agreements. Accounting Pronouncements Recently Issued, Not Yet Adopted Disclosure of Supplier Finance Program Obligations In September 2022, the FASB issued ASU 2022-04, “Supplier Finance Programs: Disclosure of Supplier Finance Program Obligations,” to improve the disclosures of supplier finance programs. Specifically, the ASU requires disclosure of key terms of the supplier finance programs and a rollforward of the related obligations. The amendments in this ASU do not affect the recognition, measurement, or financial statement presentation of obligations covered by supplier finance programs. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2022, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. The Company does not engage in supplier finance programs and, therefore, does not expect to add any incremental disclosures required by ASU 2022-04.
