NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

July 3, 2021

(Unaudited)

NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited consolidated financial statements for Cornerstone Building Brands, Inc. (together with its subsidiaries, unless otherwise indicated, the “Company,” “Cornerstone,” “we,” “us” or “our”) have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles (“GAAP”) for complete financial statements. In the opinion of management, the unaudited consolidated financial statements included herein contain all adjustments, which consist of normal recurring adjustments, necessary to fairly present the Company’s financial position, results of operations and cash flows for the periods indicated. Operating results for the period from January 1, 2021 through July 3, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2021.

 Certain reclassifications have been made to the prior period amounts in the consolidated financial statements to conform to the current presentation.

For additional information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the Securities and Exchange Commission (the “SEC”) on March 4, 2021.

Reporting Periods

The Company’s fiscal quarters are based on a four-four-five week calendar with periods ending on the Saturday of the last week in the quarter except that December 31st will always be the year-end date. Therefore, the financial results of certain fiscal quarters may not be comparable to prior fiscal quarters.

Restricted Cash

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheets that total the amounts shown in the consolidated statements of cash flows (in thousands):

	July 3, 2021		December 31, 2020
Cash and cash equivalents	$	88,978	$	674,255
Restricted cash(1)	6,224		6,223
Total cash, cash equivalents and restricted cash shown in the consolidated statements of cash flows	$	95,202	$	680,478

(1)Restricted cash primarily relates to escrow balances held for an outstanding earn-out agreement and other indemnification agreements.

Accounts Receivables and Related Allowance

The Company reports accounts receivable net of the allowance for expected credit losses. Trade accounts receivable are the result of sales of vinyl windows, aluminum windows, vinyl siding, metal siding, injection molded products, metal building products, insulated metal panels, metal coating, and other products and services to customers throughout the United States and Canada and affiliated territories, including international builders who resell to end users. Sales are primarily denominated in U.S. dollars. Credit sales do not normally require a pledge of collateral; however, various types of liens may be filed to enhance the collection process and we require payment prior to shipment for certain international shipments.

The Company establishes provisions for expected credit losses based on the Company’s assessment of the collectability of amounts owed to us by our customers. Such provisions are included in selling, general and administrative expenses. In establishing these reserves, the Company considers changes in the financial position of a customer, age of the accounts receivable balances, availability of security, unusual macroeconomic conditions, lien rights and bond rights as well as disputes, if any, with our customers. Our allowance for credit losses reflects reserves for customer receivables to reduce receivables to amounts expected to be collected. Interest on delinquent accounts receivable is included in the trade accounts receivable balance and recognized as interest income when earned and collectability is reasonably assured. Uncollectible accounts are written off when a settlement is reached for an amount that is less than the outstanding historical balance, all collection efforts have been exhausted, and/or any legal action taken by the Company has concluded.

The following table represents the rollforward of the allowance for credit losses for the periods indicated (in thousands):

	Six Months Ended
	July 3, 2021		July 4, 2020
Ending balance, prior period	$	13,313	$	9,962
Cumulative effect of accounting change(1)	—		678
Provision for expected credit losses	1,428		252
Amounts charged against allowance for credit losses, net of recoveries	(750)		(2,076)
Held for sale adjustment	(3,651)		—
Allowance for credit losses of acquired company at date of acquisition	—		810
Ending balance	$	10,340	$	9,626

(1)Cumulative effect of accounting change reflects the modified retrospective effect of adopting ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.

Net Sales

The Company enters into contracts that pertain to products, which are accounted for as separate performance obligations and are typically one year or less in duration. Given the nature of the Company's sales arrangements, we are not required to exercise significant judgment in determining the timing for the satisfaction of performance obligations or the transaction price. Revenue is measured as the amount of consideration expected to be received in exchange for our products. Revenue is generally recognized when the product has shipped from our facility and control has transferred to the customer. For a portion of our business, when we process customer owned material, control is deemed to transfer to the customer as the processing is being completed.

The Company’s revenues are adjusted for variable consideration, which includes customer volume rebates and prompt payment discounts. The Company measures variable consideration by estimating expected outcomes using analysis and inputs based upon anticipated performance, historical data, and current and forecasted information. Customer returns are recorded as a reduction to sales on an actual basis throughout the year and also include an estimate at the end of each reporting period for future customer returns related to sales recorded prior to the end of the period. The Company generally estimates customer returns based upon the time lag that historically occurs between the sale date and the return date while also factoring in any new business conditions that might impact the historical analysis such as new product introduction. Measurement of variable consideration is reviewed by management periodically and revenue is adjusted accordingly. We do not have significant financing components. The Company recognizes installation revenue, primarily within the stone veneer business, over the period for which the stone is installed, which is typically a very short duration.

Shipping and handling activities performed by us are considered activities to fulfill the sales of our products. Amounts billed for shipping and handling are included in net sales, while costs incurred for shipping and handling are included in cost of sales.

In accordance with certain contractual arrangements, we receive payment from our customers in advance related to performance obligations that are to be satisfied in the future and recognize such payments as deferred revenue, primarily related to the Company’s weathertightness warranties (see Note 12 — Warranty).

A portion of the Company’s revenue, exclusively within the Commercial segment, includes multiple-element revenue arrangements due to multiple deliverables. Each deliverable is generally determined based on customer-specific manufacturing and delivery requirements. Because the separate deliverables have value to the customer on a stand-alone basis, they are typically considered separate units of accounting. A portion of the entire job order value is allocated to each unit of accounting. Revenue allocated to each deliverable is recognized upon shipment. The Company uses estimated selling price (“ESP”) based on underlying cost plus a reasonable margin to determine how to separate multiple-element revenue arrangements into separate units of accounting, and how to allocate the arrangement consideration among those separate units of accounting. The Company determines ESP based on normal pricing and discounting practices.

NOTE 3 — ACQUISITIONS

2021 Acquisition

On April 30, 2021, the Company acquired Prime Windows LLC (“Prime Windows”) for total consideration of $93.0 million, exclusive of a $2.0 million working capital adjustment which has not been finalized as of July 3, 2021. Prime Windows serves residential new construction and repair and remodel markets with energy efficient vinyl window and door products from two manufacturing facilities in the United States, expanding our manufacturing capabilities and creating new opportunities for us in the Western United States. This acquisition was funded through borrowings under the Company’s existing credit facilities. Prime Windows’ results are reported within the Windows segment.

The Company preliminarily determined the fair value of the tangible and intangible assets and the liabilities acquired, and recorded goodwill based on the excess of the fair value of the acquisition consideration over such fair values, as follows (in thousands):

Assets acquired:
Cash	$	997
Accounts receivable	5,500
Inventories	4,295
Prepaid expenses and other current assets	823
Property, plant and equipment	2,000
Lease right of use assets	2,637
Intangible assets (trade names/customer relationships)	52,700
Goodwill	31,770
Other assets	50
Total assets acquired	100,772
Liabilities assumed:
Accounts payable	1,676
Other accrued expenses	1,429
Lease liabilities	2,637
Total liabilities assumed	5,742
Net assets acquired	$	95,030

The $31.8 million of goodwill was allocated to the Windows segment and is expected to be deductible for tax purposes. The goodwill is primarily attributable to the synergies expected to be realized.

During the three and six months ended July 3, 2021, the Company incurred $0.7 million of acquisition-related costs for Prime Windows, $0.3 million of which are recorded in strategic development and acquisition related costs in the Company’s consolidated statements of operations.

Due to the recent closing of the transaction, the purchase price allocation is preliminary and will be finalized when valuations are complete and final assessments of the fair value of acquired assets and assumed liabilities are completed. There can be no assurance that such finalization will not result in material changes from the preliminary purchase price allocations. The Company’s estimates and assumptions are subject to change during the measurement period (up to one year from the acquisition date), as the Company finalizes the valuations of accounts receivable, inventories, prepaid expenses, property, plant and equipment, lease right of use assets, goodwill, intangible assets, other assets, accounts payable, other accrued expenses, deferred income taxes and lease liabilities.

2020 Acquisition

On March 2, 2020, the Company acquired 100% of the issued and outstanding shares of the common stock of Kleary Masonry, Inc. (“Kleary”) for total consideration of $40.0 million, exclusive of the $2.0 million working capital adjustment that was finalized during the three months ended July 4, 2020. The transaction was financed with cash on hand and through borrowings under the Company’s asset-based revolving credit facility. Kleary’s results are reported within the Siding segment.

10

The Company determined the fair value of the tangible and intangible assets and the liabilities acquired, and recorded goodwill based on the excess of the fair value of the acquisition consideration over such fair values, as follows (in thousands):

Assets acquired:
Cash	$	143
Accounts receivable	7,135
Inventories	670
Prepaid expenses and other current assets	277
Property, plant and equipment	1,042
Lease right of use assets	445
Intangible assets (trade names/customer relationships)	22,350
Goodwill	12,539
Total assets acquired	44,601
Liabilities assumed:
Accounts payable	1,149
Other accrued expenses	1,020
Lease liabilities	339
Other long-term liabilities	109
Total liabilities assumed	2,617
Net assets acquired	$	41,984

The $12.5 million of goodwill from the Kleary acquisition was allocated to the Siding segment and will be deductible for tax purposes. The goodwill is attributable to the workforce of the acquired business and the synergies expected to be realized. The fair value of all assets acquired and liabilities assumed was finalized during the first quarter of 2021.

Strategic development and acquisition related costs in the consolidated statements of operations for the three and six months ended July 3, 2021 included a reduction of $4.2 million to the previously estimated accrual to reflect the final contingent earnout for the Kleary acquisition at approximately $5.4 million.

Unaudited Pro Forma Financial Information

During the three and six months ended July 3, 2021, Prime Windows contributed net sales of $13.0 million and net income of $0.7 million which has been included within the Company’s consolidated statement of operations. The following table provides unaudited supplemental pro forma results for Cornerstone for the three and six months ended July 3, 2021 and July 4, 2020 as if the Prime Windows and Kleary acquisitions had occurred on January 1, 2020 (in thousands, except for per share data):

	Three Months Ended				Six Months Ended
	July 3, 2021		July 4, 2020		July 3, 2021		July 4, 2020
Net sales	$	1,406,296	$	1,098,542	$	2,691,089	$	2,234,251
Net income (loss) applicable to common shares	9,609		28,649		9,827		(510,707)

NOTE 4 — RESTRUCTURING

The Company has various initiatives and programs in place within its business units to reduce selling, general, and administrative expenses (“SG&A”), manufacturing costs and to optimize the Company’s combined manufacturing footprint. During the six months ended July 3, 2021, the Company incurred restructuring charges of $1.0 million, $0.2 million and $3.0 million in the Windows, Siding and Commercial segments, respectively, and $2.3 million in restructuring charges at Corporate headquarters. Restructuring charges incurred to date since the current restructuring initiatives began in 2019 are $58.8 million. The following table summarizes the costs related to those restructuring plans for the three and six months ended July 3, 2021 and costs incurred to date since inception of those initiatives and programs (in thousands):

	Three Months Ended		Six Months Ended		Costs Incurred to Date
	July 3, 2021		July 3, 2021		(Since inception)
Severance	$	1,157	$	2,479	$	38,710
Asset impairments	3,495		3,988		11,856
Gain on sale of facilities, net	—		—		(1,298)
Other restructuring costs	—		23		9,559
Total restructuring costs	$	4,652	$	6,490	$	58,827

For the three and six months ended July 3, 2021, total restructuring costs are recorded within restructuring and impairment costs in the consolidated statements of operations. The asset impairments of $4.0 million for the six months ended July 3, 2021 primarily included assets held for sale that were recorded at fair value less cost to sell, which was less than the assets’ carrying amount, and the write-off of previously capitalized software development costs.

The following table summarizes our severance liability, included within other accrued expenses on the consolidated balance sheets, and cash payments made pursuant to the restructuring plans from inception through July 3, 2021 (in thousands):

	Windows		Siding		Commercial		Corporate		Total
Balance, December 31, 2018	$	—	$	85	$	—	$	2,333	$	2,418
Costs incurred	1,094		1,834		2,721		4,009		9,658

Total intangible assets				9	$	2,006,766	$	(422,162)	$	1,584,604

The Company expects to recognize amortization expense over the next five fiscal years as follows (in thousands):

2021	$	91,068
2022	181,971
2023	181,971
2024	181,689
2025	181,118

NOTE 8 — ASSETS AND LIABILITIES HELD FOR SALE

An asset or business is classified as held for sale when: (i) management has the authority and commits to a plan to sell the asset; (ii) the asset is available for immediate sale in its present condition; (iii) there is an active program to locate a buyer and the plan to sell has been initiated; (iv) the sale is probable within one year; (v) the asset is being actively marketed at a reasonable sale price relative to its current fair value; and (vi) it is unlikely that the plan to sell will be withdrawn or that significant changes to the plan will be made. Upon being classified as held for sale, the recoverability of the carrying value must be assessed. Evaluating the recoverability of the assets of a business classified as held for sale follows a defined order in which property and intangible assets subject to amortization are considered only after the recoverability of goodwill and other assets are assessed. In determining the fair value of the assets less cost to sell, we consider factors including current sales prices for comparable assets in the area, recent market analysis studies, appraisals and any recent legitimate offers. After the valuation process is completed, the assets held for sale are reported at the lower of the carrying value or fair value less cost to sell, and the assets are no longer depreciated or amortized. An impairment charge is recognized if the carrying value exceeds the fair value less cost to sell. The assets and related liabilities are aggregated and reported on separate lines of the balance sheet.

In June 2021, we entered into definitive agreements to sell our insulated metal panels (IMP) business for $1.0 billion in cash and roll-up sheet door (DBCI) business for $168 million in cash within the Commercial segment. The transactions are expected to close in the second half of 2021, subject to regulatory approval and other customary closing conditions. We determined that the assets and liabilities associated with each of these transactions met the held for sale criteria during the three months ended July 3, 2021. Accordingly, the respective assets and liabilities were classified in the consolidated balance sheet at July 3, 2021 as held for sale. Additionally, we ceased recording depreciation and amortization for the held for sale assets upon meeting the held for sale criteria. The transactions do not represent strategic shifts that will have a major effect on our operations and financial results, so they are not presented as discontinued operations. We determined the estimated fair value of these transactions based on the sales price defined by each respective definitive agreement. The estimated fair value less cost to sell exceeds the respective carrying amount for the IMP and DBCI businesses, therefore no impairment was recognized in the three months ended July 3, 2021.

14

The following table reconciles the carrying amounts of major classes of assets and liabilities that are classified as held for sale in the consolidated balance sheets (in thousands):

	July 3, 2021		December 31, 2020
Carrying amounts of major classes of assets held for sale:
Accounts receivable, net	$	65,812	$	—

Intangible assets, net	60,623		—
Other assets	1,257		—
Total assets held for sale	$	390,025	$	4,644
Carrying amounts of major classes of liabilities held for sale:

Other long-term liabilities	2,841		—
Total non-current liabilities	25,703		—
Total liabilities held for sale	$	75,927	$	—

There were no asset sales completed in the three months ended July 3, 2021. During the six months ended July 3, 2021, the Company completed the sale of certain real property assets resulting in approximately $0.7 million in net proceeds and an immaterial loss from the transaction.

Due to uncertainties in the estimation process, actual results could differ from the estimates used in our historical analysis. Our assumptions about property sales prices require significant judgment because the current market is highly sensitive to changes in economic conditions. We determined the estimated fair values of real property assets held for sale based on current market conditions and assumptions made by management, which may differ from actual results and may result in impairments if market conditions deteriorate.

NOTE 9 — LEASES

The Company leases certain manufacturing, warehouse and distribution locations, vehicles and equipment, including fleet vehicles. Many of these leases have options to terminate prior to or extend beyond the end of the term. The exercise of the majority of lease renewal options is at the Company’s sole discretion. Some lease agreements have variable payments, the majority of which are real estate agreements in which future increases in rent are based on an index. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company accounts for lease and non-lease components as a single lease component for all leases other than leases of durable tooling. The Company excludes leases with an initial term of 12 months or less from the consolidated balance sheets and recognizes related lease payments in the consolidated statements of operations on a straight-line basis over the lease term.

Operating lease liabilities are recognized based on the present value of the future minimum lease payments over the reasonably expected holding period at the commencement date of the leases. Few of the Company’s lease contracts provide a readily determinable implicit rate. For these contracts, an estimated incremental borrowing rate (“IBR”) is utilized, based on information available at the inception of the lease. The incremental borrowing rate represents an estimate of the interest rate we would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of the lease.

15

Accounting for leases may require judgment, including determining whether a contract contains a lease, the incremental borrowing rates to utilize for leases without a stated implicit rate, the reasonably certain holding period for a leased asset, and the allocation of consideration to lease and non-lease components. The allocation of the lease and non-lease components for leases of durable tooling is based on the Company’s best estimate of standalone price.

Weighted average information about the Company’s lease portfolio as of July 3, 2021 was as follows:

Weighted-average remaining lease term	6.0 years
Weighted-average IBR	5.91	%

Operating lease costs were as follows (in thousands):

NOTE 10 — SHARE-BASED COMPENSATION

Our 2003 Long-Term Stock Incentive Plan, as amended (the “Incentive Plan”), is an equity-based compensation plan that allows us to grant a variety of types of awards, including stock options, restricted stock awards, stock appreciation rights, cash awards, phantom stock awards, restricted stock unit awards (“RSUs”) and long-term incentive awards with performance conditions (“performance share units” or “PSUs”). Awards are generally granted once per year, with the amounts and types of awards determined by the Compensation Committee of our Board of Directors (the “Committee”). In connection with the Merger (as defined herein) with Ply Gem Parent, LLC (“Ply Gem”), on November 16, 2018 awards were granted to certain senior executives and key employees (the “Founders Awards”), which included stock options, RSUs, and PSUs. A portion of the Founders Awards was not granted under the Incentive Plan but was instead granted pursuant to a separate equity-based compensation plan, the Long-Term Incentive Plan. These Founders Awards were subject award agreements with the same terms and provisions as awards of the same type granted under the Incentive Plan.

As of July 3, 2021, and for all periods presented, the Founders Awards and our share-based awards under the Incentive Plan have consisted of RSUs, PSUs and stock option grants, none of which can be settled through cash payments. Both our stock options and restricted stock awards are subject only to vesting requirements based on continued employment through the end of a specified time period and typically vest in annual increments over three to five years or earlier upon death, disability or a change in control. As a general rule, option awards expire on the earlier of (i) 10 years from the date of grant, (ii) 60 days after termination of employment or service for a reason other than death, disability or retirement, or (iii) 180 days after death, disability or retirement. Awards are non-transferable except by disposition on death or to certain family members, trusts and other family entities as the Committee may approve.

Our time-based restricted stock awards are typically subject to graded vesting over a service period, which is three to five years. Our performance-based and market-based restricted stock awards are typically subject to cliff vesting at the end of the service period, which is typically three years. Our share-based compensation arrangements are equity classified and we recognize compensation cost for these awards on a straight-line basis over the requisite service period for each award grant. In the case of performance-based awards, expense is recognized based upon management’s assessment of the probability that such performance conditions will be achieved. Certain of our awards provide for accelerated vesting upon a change of control or upon termination without cause or for good reason.

Vesting of the PSUs granted as part of the Founders Awards is contingent upon the achievement of synergies captured from the Merger and continued employment. Based on achieved synergies during the period comprising the two fiscal years ended December 31, 2020, the Founders Awards will vest at 200% of target amounts, subject to continuing employment through the requisite service period ending on November 16, 2021. Vesting of the PSUs granted under the Incentive Plan during the six months ended July 3, 2021 and July 4, 2020 are contingent upon achievement of a cumulative three-year EBITDA growth target with an additional modifier based on total shareholder return. The grant-date fair value of the PSUs granted during the six months ended July 3, 2021 and July 4, 2020 were determined by a Monte Carlo simulation.

Stock option awards

During the six months ended July 3, 2021 and July 4, 2020, we granted 0.6 million and 1.0 million stock options, respectively. The average grant date fair value of options granted during the six months ended July 3, 2021 and July 4, 2020 was $6.50 and $1.96 per share, respectively. There were 0.1 million options with an intrinsic value of $0.7 million exercised during the six months ended July 3, 2021 and cash received from the options exercised was $1.5 million. No options were exercised during the six months ended July 4, 2020.

Restricted stock units and performance share units

Annual awards to our key employees generally have a three-year performance period. The fair value of RSUs awarded is based on the Company’s stock price as of the date of grant. During the six months ended July 3, 2021, we granted RSUs to key employees with a fair value of $11.6 million representing approximately 0.8 million shares. During the six months ended July 4, 2020, we granted RSUs to key employees with a fair value of $6.1 million, representing 1.3 million shares. During the six months ended July 3, 2021 and July 4, 2020, we granted PSUs with a total fair value of approximately $14.4 million and $5.4 million, respectively, to key employees.

Share-based compensation expense

During the three and six months ended July 3, 2021, we recorded share-based compensation expense for all awards of $5.3 million and $8.6 million, respectively. During the three and six months ended July 4, 2020, we recorded share-based compensation expense for all awards of $5.2 million and $8.5 million, respectively.

NOTE 11 — EARNINGS PER COMMON SHARE

Basic earnings per common share is computed by dividing net income allocated to common shares by the weighted average number of common shares outstanding. Diluted earnings per common share, if applicable, considers the dilutive effect of common stock equivalents. The reconciliation of the numerator and denominator used for the computation of basic and diluted earnings per common share is as follows (in thousands, except per share data):

	Three Months Ended				Six Months Ended
	July 3, 2021		July 4, 2020		July 3, 2021		July 4, 2020
Numerator for Basic and Diluted Earnings Per Common Share
Net income (loss) applicable to common shares	$	8,804	$	26,457	$	7,179	$	(515,174)
Denominator for Basic and Diluted Earnings Per Common Share
Weighted average basic number of common shares outstanding	125,863		125,754		125,683		125,927
Common stock equivalents:
Employee stock options	978		1		786		—
PSUs and Performance Share Awards	—		—		—		—
Weighted average diluted number of common shares outstanding	126,841		125,755		126,469		125,927

Diluted income (loss) per common share	$	0.07	$	0.21	$	0.06	$	(4.09)
Incentive Plan securities excluded from dilution(1)	130		4,358		216		3,338

(1)Represents securities not included in the computation of diluted earnings per common share because their effect would have been anti-dilutive.

We calculate earnings per share using the “two-class” method, whereby unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are “participating securities” and, therefore, these participating securities are treated as a separate class in computing earnings per share. The calculation of earnings per share presented here excludes the income attributable to unvested restricted stock units from the numerator and excludes the dilutive impact of those shares from the denominator. Awards subject to the achievement of performance conditions or market conditions for which such conditions had been met at the end of any of the fiscal periods presented are included in the computation of diluted earnings per common share if their effect was dilutive.

NOTE 12 — WARRANTY

The Company offers a number of warranties associated with the products it sells. The specific terms and conditions of these warranties vary depending on the product sold. The Company’s warranty liabilities are undiscounted and adjusted for inflation based on third party actuarial estimates. Factors that affect the Company’s warranty liabilities include the number of units sold, historical and anticipated rates of warranty claims, cost per claim and new product introduction. Warranties are normally limited to replacement or service of defective components for the original customer. Some warranties are transferable to subsequent owners and are generally limited to ten years from the date of manufacture or require pro-rata payments from the customer. A provision for estimated warranty costs is recorded based on historical experience and the Company periodically adjusts these provisions to reflect actual experience. Warranty costs are included within cost of goods sold. The Company assesses the adequacy of the recorded warranty claims and adjusts the amounts as necessary. Separately, upon the sale of a weathertightness warranty in the Commercial segment, the Company records the resulting revenue as deferred revenue, which is included in other accrued expenses and other long-term liabilities on the consolidated balance sheets depending on when the revenues are expected to be recognized.

18

The following table represents the rollforward of our accrued warranty obligation and deferred warranty revenue activity for the six months ended July 3, 2021 and July 4, 2020 (in thousands):

	Six Months Ended

The current portion of the warranty liabilities are recorded within other accrued expenses and the long-term portion of the warranty liabilities are recorded within other long-term liabilities in the Company’s consolidated balance sheets.

NOTE 13 — DEFINED BENEFIT PLANS

RCC Pension Plan — With the acquisition of Robertson-Ceco II Corporation (“RCC”) on April 7, 2006, we assumed a defined benefit plan (the “RCC Pension Plan”). Benefits under the RCC Pension Plan are primarily based on years of service and the employee’s compensation. The RCC Pension Plan is frozen and, therefore, employees do not accrue additional service benefits. Plan assets of the RCC Pension Plan are invested in broadly diversified portfolios of government obligations, mutual funds, stocks, bonds, fixed income securities and master limited partnerships.

CENTRIA Benefit Plans — As a result of the CENTRIA Acquisition on January 16, 2015, we assumed noncontributory defined benefit plans covering certain hourly employees (the “CENTRIA Benefit Plans”) and which are closed to new participants. Benefits under the CENTRIA Benefit Plans are calculated based on fixed amounts for each year of service rendered, although benefits accruals for one of the plans previously ceased. Plan assets of the CENTRIA Benefit Plans are invested in fixed income funds. CENTRIA also sponsors postretirement medical and life insurance plans that cover certain of its employees and their spouses (the “OPEB Plans”). Currently, the Company’s policy is to fund the CENTRIA Benefit Plans as required by minimum funding standards of the Internal Revenue Code.

Ply Gem Pension Plans — As a result of the Merger on November 16, 2018, we assumed the Ply Gem Group Pension Plan (the “Ply Gem Plan”) and the MW Manufacturers, Inc Retirement Plan (the “MW Plan”). The Ply Gem Plan was frozen during 1998, and no further increases in benefits for participants may occur as a result of increases in service years or compensation. The MW Plan was frozen for salaried participants during 2004 and non-salaried participants during 2005. No additional participants may enter the plan, but increases in benefits for participants as a result of increase in service years or compensation will occur.

We refer to the RCC Pension Plan, the CENTRIA Benefit Plans, the Ply Gem Plan and the MW Plan collectively as the “Defined Benefit Plans” in this Note.

Amortization of net actuarial loss	17		27		35		54
Net periodic benefit cost	$	67	$	90	$	133	$	180

We expect to contribute $3.2 million to the Defined Benefit Plans and $0.7 million to OPEB Plans in the year ending December 31, 2021. Our policy is to fund the CENTRIA Benefit Plans as required by minimum funding standards of the Internal Revenue Code. The contributions to the OPEB Plans by retirees vary from none to 25% of the total premiums paid.

NOTE 14 — LONG-TERM DEBT

Total long-term debt, less current portion	$	3,180,759	$	3,563,429

(1)Includes the unamortized discounts and unamortized deferred financing costs associated with the term loan facility, the 8.00% senior notes due April 2026 (included in December 31, 2020 balance only as the notes were redeemed in full in April 2021), and the 6.125% senior notes due January 2029. The unamortized deferred financing costs associated with the asset-based and revolving credit facilities of $1.5 million and $1.7 million as of July 3, 2021 and December 31, 2020, respectively, are classified in other assets on the consolidated balance sheets.

Term Loan Facility due April 2028 and Cash Flow Revolver

On April 12, 2018, Ply Gem Midco entered into a Cash Flow Agreement (the "Current Cash Flow Credit Agreement"), which provides for (i) a term loan facility (the “Existing Term Loan Facility”) in an original aggregate principal amount of $1,755.0 million, issued with a discount of 0.5%, and (ii) a cash flow-based revolving credit facility (the “Existing Cash Flow Revolver” and together with the Existing Term Loan Facility, the “Existing Cash Flow Facilities”) of up to $115.0 million.

20

On November 16, 2018, the Company entered into an incremental term loan facility in connection with the Merger, which increased the aggregate principal amount of the Existing Term Loan Facility by $805.0 million. The proceeds of this incremental term loan facility were used to, among other things, (a) finance the Merger and to pay certain fees, premiums and expenses incurred in connection therewith, (b) repay in full amounts outstanding under the Pre-merger Term Loan Credit Agreement and the Pre-merger ABL Credit Agreement and (c) repay $325.0 million of borrowings outstanding under the ABL Facility. On November 16, 2018, in connection with the consummation of the Merger, NCI and Ply Gem Midco entered into a joinder agreement with respect to the Existing Cash Flow Facilities, and the Company became the Borrower (as defined in the Current Cash Flow Credit Agreement) under the Existing Cash Flow Facilities.

On April 15, 2021, the Company entered into a Second Amendment to the Current Cash Flow Credit Agreement (the “Second Amendment"), among the Company, the several banks and other financial institutions party thereto (the "Cash Flow Lenders") and JPMorgan Chase Bank, N.A., as administrative agent and collateral agent (the “Cash Flow Agent”), which amended the Current Cash Flow Credit Agreement to, among other things:

•Terminate $92.0 million of commitments by Cash Flow Lenders under the Company’s cash flow-based revolving credit facility of up to $115.0 million, maturing on April 12, 2023 (the “Existing Cash Flow Revolver”) and;

•Replace such commitments with $92.0 million of extended cash flow-based revolving commitments, maturing on April 12, 2026 (the “Extended Cash Flow Revolver” and together with the Existing Cash Flow Revolver, the “ Current Cash Flow Revolver”).

On April 15, 2021, the Company entered into (i) a Third Amendment to Current Cash Flow Credit Agreement (the “Third Amendment”), among the Company, the subsidiary guarantors parties thereto, the Cash Flow Lenders party thereto and the Cash Flow Agent and (ii) an Increase Supplement (the “Increase Supplement”), between the Company and JPMorgan Chase Bank, N.A., as the increasing lender. The Third Amendment amended the Current Cash Flow Credit Agreement to, among other things, refinance the Existing Term Loan Facility in an original aggregate principal amount of $1,755.0 million with Tranche B Term Loans in an aggregate principal amount of approximately $2,491.6 million, maturing on April 12, 2028. The Increase Supplement supplemented the Current Cash Flow Credit Agreement to, among other things, increase the aggregate principal amount of the Tranche B Term Loan Facility by approximately $108.4 million (the “Incremental Tranche B Term Loans”), for a total principal amount of $2,600.0 million (the “Current Term Loan Facility” and together with the Current Cash Flow Revolver, the “Current Cash Flow Facilities”). Proceeds of the Incremental Tranche B Term Loans were used, together with cash on hand, (i) for the redemption of all of the 8.00% Senior Notes (as defined below) (the “Senior Notes Redemption”) and (ii) to pay any fees and expenses incurred in connection with the extension and refinancing of the Company’s senior credit facilities and the Senior Notes Redemption.

In connection with the Third Amendment and the Increase Supplement to the Current Cash Flow Credit Agreement, we incurred $21.8 million and $24.8 million in financing costs for the three and six months ended July 3, 2021, respectively, of which $13.1 million and $13.2 million, respectively, were deferred and will be amortized using the effective interest method.

The Current Term Loan Facility amortizes in nominal quarterly one installments equal to one percent of the aggregate initial principal amount thereof per annum, with the remaining balance payable upon final maturity. The Current Term Loan Facility bears annual interest at a floating rate measured by reference to, at the Company’s option, either (i) an adjusted LIBOR rate (subject to a floor of 0.50%) plus an applicable margin of 3.25% per annum or (ii) an alternate base rate plus an applicable margin of 2.25% per annum. At July 3, 2021, the interest rates on the Current Term Loan Facility were as follows:

	July 3, 2021
Interest rate	3.75	%
Effective interest rate	4.02	%

The Company entered into certain interest rate swap agreements in 2019 and 2021 to effectively convert a portion of its variable rate debt to fixed. See Note 15 — Derivatives.

Loans outstanding under the Current Cash Flow Revolver bear annual interest at a floating rate measured by reference to, at the Company’s option, either (i) an adjusted LIBOR rate (subject to a floor of 0.00%) plus an applicable margin ranging from 2.50% to 3.00% per annum depending on the Company’s secured leverage ratio or (ii) an alternate base rate plus an applicable margin ranging from 1.50% to 2.00% per annum depending on the Company’s secured leverage ratio. There are no amortization payments under the Current Cash Flow Revolver. Additionally, unused commitments under the Current Cash Flow Revolver are subject to a fee ranging from 0.25% to 0.50% per annum depending on the Company’s secured leverage ratio.

21

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

Subject to certain exceptions, the Current Term Loan Facility is subject to mandatory prepayments in an amount equal to:

•the net cash proceeds of (1) certain asset sales, (2) certain debt offerings and (3) certain insurance recovery and condemnation events; and

•50% of annual excess cash flow (as defined in the Current Cash Flow Credit Agreement), subject to reduction to 25% and 0% if specified secured leverage ratio targets are met to the extent that the amount of such excess cash flow exceeds $10.0 million. For 2020, no payments were required under the excess cash flow calculation.

The obligations under the Current Cash Flow Credit Agreement are guaranteed by each direct and indirect wholly-owned U.S. restricted subsidiary of the Company, subject to certain exceptions, and are secured by:

•a perfected security interest in substantially all tangible and intangible assets of the Company and each subsidiary guarantor (other than ABL Priority Collateral (as defined below)), including the capital stock of each direct material wholly-owned U.S. restricted subsidiary owned by the Company and each subsidiary guarantor, and 65% of the capital stock of any non-U.S. subsidiary held directly by the Company or any subsidiary guarantor, subject to certain exceptions (the “Cash Flow Priority Collateral”), which security interest will be senior to the security interest in the foregoing assets securing the Current ABL Facility; and

•a perfected security interest in the ABL Priority Collateral, which security interest will be junior to the security interest in the ABL Priority Collateral securing the Current ABL Facility.

The Current Cash Flow Revolver includes a financial covenant set at a maximum secured leverage ratio of 7.75:1.00, which will apply if the outstanding amount of loans and drawings under letters of credit which have not then been reimbursed exceeds a specified threshold at the end of any fiscal quarter.

ABL Facility due April 2026

On April 12, 2018, Ply Gem Midco entered into an ABL Credit Agreement (the "Current ABL Credit Agreement"), which provides for an asset-based revolving credit facility (the “Existing ABL Facility”) of up to $360.0 million, consisting of (i) $285.0 million available to U.S. borrowers (subject to U.S. borrowing base availability) (the “ABL U.S. Facility”) and (ii) $75.0 million available to both U.S. borrowers and Canadian borrowers (subject to U.S. borrowing base and Canadian borrowing base availability) (the “ABL Canadian Facility”). The Company and, at their option, certain of their subsidiaries are the borrowers under the Existing ABL Facility.

On October 15, 2018, Ply Gem Midco entered into an incremental asset-based revolving credit facility of $36.0 million, which upsized the Existing ABL Facility to $396.0 million in the aggregate, and with (x) the ABL U.S. Facility being increased from $285.0 million to $313.5 million and (y) the ABL Canadian Facility being increased from $75.0 million to $82.5 million.

On November 16, 2018, Ply Gem Midco entered into an incremental asset-based revolving credit facility of $215.0 million in connection with the Merger, which upsized the Existing ABL Facility to $611.0 million in the aggregate, and with (x) the ABL U.S. Facility being increased from $313.5 million to approximately $483.7 million and (y) the ABL Canadian Facility being increased from $82.5 million to approximately $127.3 million. On November 16, 2018, in connection with the consummation of the Merger, the Company and Ply Gem Midco entered into a joinder agreement with respect to the Existing ABL Facility, and the Company became the Parent Borrower (as defined in the ABL Credit Agreement) under the Existing ABL Facility.

On April 15, 2021, the Company entered into Amendment No. 6 to the Current ABL Credit Agreement, by and among the Company, the subsidiary borrowers party thereto, the several banks and financial institutions party thereto and UBS AG, Stamford Branch, as administrative agent and collateral agent, which amended the ABL Credit Agreement in order to, among other things:

•Terminate the existing revolving commitments of each of the Extending ABL Credit Lenders (as defined in therein), originally maturing on April 12, 2023 (the “Existing ABL Commitments”); and

•Replace the Existing ABL Commitments with an extended revolving commitment of $611.0 million, maturing on April 12, 2026 (the “Current ABL Facility”).

22

Borrowing availability under the Current ABL Facility is determined by a monthly borrowing base collateral calculation that is based on specified percentages of the value of eligible inventory, eligible accounts receivable and eligible credit card receivables, less certain reserves and subject to certain other adjustments as set forth in the Current ABL Credit Agreement. Availability is reduced by issuance of letters of credit as well as any borrowings. As of July 3, 2021, the Company had the following in relation to the Current ABL Facility (in thousands):

	July 3, 2021
Excess availability	$	403,994
Revolving loans outstanding	160,000
Letters of credit outstanding	40,902

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

The obligations under the Current ABL Credit Agreement are guaranteed by each direct and indirect wholly-owned U.S. restricted subsidiary of the Company, subject to certain exceptions, and are secured by:

•a perfected security interest in all present and after-acquired inventory, accounts receivable, deposit accounts, securities accounts, and any cash or other assets in such accounts and other related assets owned by the Company and the U.S. subsidiary guarantors and the proceeds of any of the foregoing, except to the extent such proceeds constitute Cash Flow Priority Collateral, and subject to certain exceptions (the “ABL Priority Collateral”), which security interest is senior to the security interest in the foregoing assets securing the Current Cash Flow Facilities; and

•a perfected security interest in the Cash Flow Priority Collateral, which security interest will be junior to the security interest in the Cash Flow Collateral securing the Current Cash Flow Facilities.

Additionally, the obligations of the Canadian borrowers under the Current ABL Credit Agreement are guaranteed by each direct and indirect wholly-owned Canadian restricted subsidiary of the Canadian borrowers, subject to certain exceptions, and are secured by substantially all assets of the Canadian borrowers and the Canadian subsidiary guarantors, subject to certain exceptions.

The Current ABL Credit Agreement includes a minimum fixed charge coverage ratio of 1.00:1.00, which is tested only when specified availability is less than 10.0% of the lesser of (x) the then applicable borrowing base and (y) the then aggregate effective commitments under the Current ABL Facility, and continuing until such time as specified availability has been in excess of such threshold for a period of 20 consecutive calendar days.

6.125% Senior Notes due January 2029

On September 24, 2020, the Company issued $500.0 million in aggregate principal amount of 6.125% Senior Notes due January 2029 (“the 6.125% Senior Notes”). Proceeds from the 6.125% Senior Notes were used to repay outstanding amounts under the Company’s Current ABL Facility and Current Cash Flow Revolver. The 6.125% Senior Notes bear interest at 6.125% per annum and will mature on January 15, 2029. Interest is payable semi-annually in arrears on January 15 and July 15 commencing on January 15, 2021. The effective interest rate for the 6.125% Senior Notes was 6.33% as of July 3, 2021, after considering each of the different interest expense components of this instrument, including the coupon payment and the deferred debt issuance costs.

The 6.125% Senior Notes are guaranteed on a senior unsecured basis by each of the Company’s existing and future wholly-owned domestic subsidiaries that guarantee the Company’s obligations under the Current Cash Flow Facilities or the Current ABL Facility (including by reason of being a borrower under the Current ABL Facility on a joint and several basis with the Company or a subsidiary guarantor). The 6.125% Senior Notes are unsecured senior indebtedness and are effectively subordinated to all of the Company’s existing and future senior secured indebtedness, including indebtedness under the Current Term Loan Facility, Current Cash Flow Revolver and Current ABL Facility, and are senior in right of payment to future subordinated indebtedness of the Company.

The Company may redeem the 6.125% Senior Notes in whole or in part at any time as set forth below:

•prior to September 15, 2023, at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to but not including the redemption date, plus the applicable make-whole premium;

•prior to September 15, 2023, up to 40% of the aggregate principal amount with the proceeds of certain equity offerings at a redemption price of 106.125% plus accrued and unpaid interest, if any, to but not including the redemption date;

23

•on or after September 15, 2023 and prior to September 15, 2024, at a price equal to 103.063% of the principal amount thereof, plus accrued and unpaid interest, if any, to but not including the redemption date;

•on or after September 15, 2024 and prior to September 15, 2025, at a price equal to 101.531% of the principal amount thereof, plus accrued and unpaid interest, if any, to but not including the redemption date; and

•on or after September 15, 2025, at a price equal to 100.000% of the principal amount thereof, plus accrued and unpaid interest, if any, to but not including the redemption date.

Redemption of 8.00% Senior Notes

On April 15, 2021, the Company redeemed the outstanding $645.0 million aggregate principal amount of the 8.00% Senior Notes due April 2026 (the “8.00% Senior Notes”) for $670.8 million using cash on hand and proceeds from the Incremental Tranche B Term Loans. The redemption resulted in a pre-tax loss on extinguishment of debt of $41.9 million during the three and six months ended July 3, 2021, comprising a make-whole premium of $25.8 million and a write-off of $16.1 million in unamortized deferred financing costs.

Debt Covenants

The Company’s debt agreements contain a number of covenants that, among other things, limit or restrict the ability of the Company and its subsidiaries to incur additional indebtedness; make dividends and other restricted payments; incur additional liens; consolidate, merge, sell or otherwise dispose of all or substantially all assets; make investments; transfer or sell assets; enter into restrictive agreements; change the nature of the business; and enter into certain transactions with affiliates. As of July 3, 2021, the Company was in compliance with all covenants that were in effect on such date.

NOTE 15 — DERIVATIVES

We utilize derivative instruments, including interest rate swap agreements and foreign currency hedging contracts, to manage our exposure to interest rate risk and currency fluctuations. We only hold such instruments for economic hedging purposes, not for speculative or trading purposes. Our derivative instruments are transacted only with highly rated institutions, which reduces our exposure to credit risk in the event of nonperformance.

Interest Rate Swaps

We are exposed to interest rate risk associated with fluctuations in interest rates on our floating-rate Current Term Loan Facility. The objective in using interest rate derivatives is to manage our exposure to interest rate movements. To accomplish this objective, we have entered into interest rate swap agreements as part of our interest rate risk management strategy. Interest rate swaps involve the receipt of variable amounts from a counterparty in exchange for the company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

On a monthly basis, we net settle with our swap counterparties for the difference between the fixed rate specified in each swap agreement and the variable rate as applied to the notional amount of the swap.

In May 2019, the Company entered into four-year interest rate swaps to mitigate variability in forecasted interest payments on $1,500.0 million of the Company’s Current Term Loan Facility. The interest rate swaps effectively converted a portion of the floating rate interest payment into a fixed rate interest payment. Three interest rate swaps each covered of notional amount of $500.0 million. The Company designated the interest rate swaps as qualifying hedging instruments and accounted for these derivatives as cash flow hedges.

As discussed in Note 14 — Long-Term Debt, the Company refinanced its Term Loan Facility. Contemporaneously with the refinancing on April 15, 2021, we completed a series of transactions to modify our interest rate swap positions as follows: (i) we de-designated all existing interest rate swaps as cash flow hedges; (ii) we terminated two existing interest rate swaps with a notional value of $500 million each; (iii) we entered into two receive-fixed interest rate swaps with a notional amount of $250 million each, which are designed to offset the terms of an existing, active interest rate swap with a notional amount of $500 million; and (iv) we entered into two pay-fixed interest rate swaps with a notional amount of $750 million each, effectively blending the liability position of our existing interest rate swap agreements into the new swaps and extending the term of our hedged position to April 2026.

The amount remaining in accumulated other comprehensive loss for the de-designated and terminated swaps at the de-designation date was approximately $65.5 million and will be amortized as an increase to interest expense over the effective period of the original swap agreements.

The new receive-fixed interest rate swaps will remain undesignated to economically offset the now undesignated existing, active swap. The new receive-fixed and the existing, active swaps mature on July 12, 2023. Cash settlements related to these receive-fixed interest rate swaps will offset and are classified as operating activities in the consolidated statements of cash flows.

24

The new pay-fixed interest rate swaps also qualify as hybrid instruments in accordance with ASC 815, Derivatives and Hedging, consisting of a loan and an embedded at-market derivative that was designated as a cash flow hedge. The loan is accounted for at amortized cost over the life of the swap while the embedded at-market derivative is accounted for at fair value. The new swaps are indexed to one-month LIBOR and will be net settled on a monthly basis with the counterparty for the difference between the fixed rate of 2.0369% and 2.0340%, respectively, and the variable rate based upon one-month LIBOR (subject to a floor of 0.5%) as applied to the notional amount of the swaps. In connection with the transactions discussed above, no cash was exchanged between the Company and the counterparty. The liability of the terminated interest rate swaps as well as the inception value of the receive-fixed interest rate swap was blended into the new pay-fixed interest rate swap. The cash flows related to the portion treated as debt will be classified as financing activities in the consolidated statements of cash flows while the portion treated as an at-market derivative will be classified as operating activities.

The key terms of interest rate swaps are as follows (amounts in thousands):

			July 3, 2021			December 31, 2020
Effective Date	Fixed Rate Paid (Received)		Notional Amount		Status	Notional Amount		Status	Maturity Date

			$	1,500,000		$	1,500,000

Our interest rate swap agreements, excluding the portion treated as debt, are recognized at fair value in the consolidated balance sheets and are valued using pricing models that rely on market observable inputs such as yield curve data, which are classified as Level 2 inputs within the fair value hierarchy.

Foreign Currency Hedging Contracts

In December 2020, the Company entered into forward contracts to hedge approximately $66.0 million of its 2021 non-functional currency inventory purchases. These forward contracts were established to protect the Company from variability in cash flows attributable to changes in the U.S. dollar relative to the Canadian dollar. The forward contracts are highly correlated to the changes in the U.S. dollar relative to the Canadian dollar. Unrealized gains and losses on these contracts are designated as effective or ineffective. The effective portion of such gains or losses is recorded as a component of accumulated other comprehensive income or loss, while the ineffective portion of such gains or losses is recorded as a component of cost of goods sold. Future realized gains and losses in connection with each inventory purchase will be reclassified from accumulated other comprehensive income or loss to cost of goods sold. The gains and losses on the derivative contracts that are reclassified from accumulated other comprehensive income or loss to current period earnings are included in the line item in which the hedged item is recorded in the same period the forecasted transaction affects earnings.

During the three months ended July 3, 2021, the Company entered into forward contracts to hedge approximately $20.2 million of its 2022 non-functional currency inventory purchases. Similar to the December 2020 contracts described above, these contracts were established to protect the Company from variability in cash flows attributable to changes in the U.S dollar relative to the Canadian dollar. All of the Company’s foreign currency forward contracts are designated as qualifying hedging instruments and are accounted for as cash flow hedges in accordance with ASC 815, Derivatives and Hedging.

During the three and six months ended July 3, 2021, the Company realized a loss of approximately $0.4 million and $0.5 million, respectively within cost of goods sold in the consolidated statements of operations based on the foreign currency forward contracts described above. The changes in fair values of derivatives that have been designated and qualify as cash flow hedges are recorded in accumulated other comprehensive income or loss and are reclassified into cost of goods sold in the same period the hedged item affects earnings. Due to the high degree of effectiveness between the hedging instruments and the underlying exposures being hedged, fluctuations in the value of the derivative instruments are generally offset by changes in the fair value or cash flows of the underlying exposures being hedged. The changes in the fair value of derivatives that do not

25

qualify as effective are immediately recognized in earnings. As of July 3, 2021, the Company had a hedge liability of approximately $1.3 million and a loss of approximately $1.4 million in accumulated other comprehensive loss on the consolidated balance sheets. No hedge liability or asset or deferred gain or loss in accumulated other comprehensive loss existed as of December 31, 2020 related to the forward contracts.

NOTE 17 — STOCK REPURCHASE PROGRAM

The Company announced that its Board of Directors authorized new stock repurchase programs for the repurchase of up to $50.0 million of the Company’s outstanding Common Stock on October 10, 2017 and March 7, 2018, for a cumulative total of $100.0 million. Under these repurchase programs, the Company is authorized to repurchase shares at times and in amounts that it deems appropriate in accordance with all applicable securities laws and regulations. Shares repurchased pursuant to the repurchase programs are usually retired. There is no time limit on the duration of the programs. Following repurchases made during the three months ended July 4, 2020, no authorized amount remained available under the program announced on October 10, 2017.

During the six months ended July 3, 2021, there were no stock repurchases under the stock repurchase programs. The Company repurchased 1.1 million shares for $6.4 million under the stock repurchase programs during the six months ended July 4, 2020. As of July 3, 2021, $49.1 million remained available for stock repurchases under the program announced on March 7, 2018. The timing and method of any repurchases, which will depend on a variety of factors, including market conditions, are subject to results of operations, financial conditions, cash requirements and other factors, and may be suspended or discontinued at any time.

During the six months ended July 3, 2021 and July 4, 2020, the Company withheld approximately 0.1 million and 0.1 million shares, respectively, of stock to satisfy minimum tax withholding obligations arising in connection with the vesting of stock awards, which are included in treasury stock purchases in the consolidated statements of stockholders’ equity.

27

During the six months ended July 3, 2021 and July 4, 2020, the Company cancelled approximately 0.1 million and 1.2 million shares that had been previously withheld to satisfy minimum tax withholding obligations arising in connection with the vesting of stock awards and shares repurchased under the stock repurchase programs. The cancellations resulted in $1.5 million and $6.9 million decreases in both treasury stock and additional paid in capital during the six months ended July 3, 2021 and July 4, 2020, respectively.

NOTE 18 — FAIR VALUE OF FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, restricted cash, trade accounts receivable and accounts payable approximate fair value as of July 3, 2021 and December 31, 2020, respectively, because of their relatively short maturities. The carrying amounts of the indebtedness under the Current ABL Facility and Current Cash Flow Revolver approximate fair value as the interest rates are variable and reflective of market rates. At July 3, 2021, there was $160.0 million of borrowings outstanding under the Current ABL Facility and no outstanding indebtedness under the Current Cash Flow Revolver. The fair values of the remaining financial instruments not currently recognized at fair value on our consolidated balance sheets at the respective period ends were (in thousands):

	July 3, 2021				December 31, 2020
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Term Loan Facility	$	2,593,500	$	2,589,610	$	2,497,967	$	2,485,477
8.00% Senior Notes	—		—		645,000		674,025
6.125% Senior Notes	500,000		536,250		500,000		530,000

The fair value of the term loan facility was based on recent trading activities of comparable market instruments, which are level 2 inputs and the fair values of the 8.00% and 6.125% senior notes were based on quoted prices in active markets for the identical liabilities, which are level 1 inputs.

Fair Value Measurements

ASC Subtopic 820-10, Fair Value Measurements and Disclosures, requires us to use valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized as follows:

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

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

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

The following is a description of the valuation methodologies used for assets and liabilities measured at fair value. There have been no changes in the methodologies used as of July 3, 2021 and December 31, 2020.

Money market: Money market funds have original maturities of three months or less. The original cost of these assets approximates fair value due to their short-term maturity.

Mutual funds: Mutual funds are valued at the closing price reported in the active market in which the mutual fund is traded. 

Assets held for sale: Assets held for sale are valued based on current market conditions, prices of similar assets in similar condition and expected proceeds from the sale of the assets.

Deferred compensation plan liability: Deferred compensation plan liability is comprised of phantom investments in the deferred compensation plan and is valued at the closing price reported in the active markets in which the money market and mutual funds are traded.

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

28

Foreign currency hedges: The fair value of the foreign currency forward contracts are estimated using industry standard valuation models using market-based observable inputs, including spot rates, forward points, interest rates and volatility inputs (Level 2).

The following tables summarize information regarding our financial assets and liabilities that are measured at fair value on a recurring basis as of July 3, 2021 and December 31, 2020, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (in thousands):

(1)Unrealized holding gains (losses) for the six months ended July 3, 2021 and July 4, 2020 were $0.2 million and $(0.7) million, respectively. These unrealized holding gains (losses) were substantially offset by changes in the deferred compensation plan liability.

(2)The Company records the short-term investments in deferred compensation plan within investments in debt and equity securities, at market, and the deferred compensation plan liability within accrued compensation and benefits on the consolidated balance sheets.

(3)The balance as of July 3, 2021 of $19,518 is related to receive-fixed interest rate swap for which the fair value option has been elected.

29

(4)The balance as of July 3, 2021 includes $63.1 million related to the financing component of pay-fixed interest rate swaps and $19.5 million related to pay-fixed May 2019 active interest rate swap which has been de-designated as cash flow hedge.

The following table summarizes information regarding our financial assets that are measured at fair value on a nonrecurring basis as of July 3, 2021, segregated by level of the valuation inputs within the fair value hierarchy utilized to measure fair value (in thousands):

(1)Assets held for sale are reported at fair value, if, on an individual basis, the fair value of the asset less cost to sell is less than its carrying amount. The fair value of assets held for sale is estimated using Level 3 inputs, such as broker quotes for like-kind assets or other market indications of a potential selling value that approximates fair value.

NOTE 19 — INCOME TAXES

Under FASB ASC 740-270, Income Taxes - Interim Reporting, each interim period is considered an integral part of the annual period and tax expense is measured using an estimated annual effective tax rate. Estimates of the annual effective tax rate at the end of interim periods are, of necessity, based on evaluations of possible future events and transactions and may be subject to subsequent refinement or revision. The Company calculates its quarterly tax provision consistent with the guidance provided by ASC 740-270, whereby the Company forecasts its estimated annual effective tax rate then applies that rate to its year-to-date ordinary pre-tax book income (loss). In addition, the Company excludes jurisdictions with a projected loss for the year or the year-to-date ordinary loss where the Company cannot recognize a tax benefit from its estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections. In addition to the tax resulting from applying the estimated annual effective tax rate to pre-tax book income (loss), the Company includes certain items treated as discrete events to arrive at an estimated effective tax rate. Future changes in the forecasted annual income (loss) projections, tax rate changes, or discrete tax items could result in significant adjustments to quarterly income tax expense in future periods in accordance with ASC 740-270.

For the six months ended July 3, 2021, the Company’s estimated annual effective income tax of ordinary forecasted pre-tax book income was approximately 31.9%, which varied from the statutory rate primarily due to state income tax expense, valuation allowances, and foreign income taxes. For the six months ended July 3, 2021, the effective tax rate was (3.9)%, which varied from the annual effective tax rate due to discrete items recorded during the period, including interest recorded on unrecognized tax benefits, adjustments to state income tax rates, and stock compensation.

Valuation allowance

As of July 3, 2021, the Company remained in a valuation allowance position, in the amount of $12.0 million, against its deferred tax assets for certain state jurisdictions of certain entities as it is currently deemed “more likely than not” that the benefit of such net tax assets will not be utilized as the Company continues to be in a three-year cumulative loss position for these state jurisdictions. The Company will continue to monitor the positive and negative factors for these jurisdictions and make further changes to the valuation allowances as necessary.

Unrecognized tax benefits

Despite the Company’s belief that its tax return positions are consistent with applicable tax laws, the Company believes that certain positions could be challenged by taxing authorities. The Company’s tax reserves reflect the difference between the tax benefit claimed on tax returns and the amount recognized in the consolidated financial statements. These reserves have been established based on management’s assessment as to potential exposure attributable to permanent differences as well as interest and penalties applicable to both permanent and temporary differences. The tax reserves are reviewed periodically and adjusted in light of changing facts and circumstances, such as progress of tax audits, lapse of applicable statutes of limitations and changes in tax law. The Company is currently under examination by various taxing authorities. During the six months ended July 3, 2021, the tax reserves increased by approximately $6.2 million. The increase is primarily due to a new uncertain tax benefit and additional interest expense related to previously recorded unrecognized tax benefits.

The liability for unrecognized tax benefits as of July 3, 2021 was approximately $17.9 million and is recorded in other long-term liabilities in the consolidated balance sheet.

30

CARES Act

Under the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) that was signed into law on March 27, 2020, the Company elected to defer employer side social security payments for approximately $19.9 million as of December 31, 2020, $10 million of which is recorded in current liabilities on the consolidated balance sheet. Approximately $10 million of the deferral will be paid by December 31, 2021 and the remainder will be paid by December 31, 2022.

NOTE 20 — SEGMENT INFORMATION

Operating segments are defined as components of an enterprise that engage in business activities for which discrete financial information is available and is evaluated on a regular basis by the chief operating decision maker to make decisions regarding the allocation of resources to the segment and assess the performance of the segment. The Company has three reportable segments: Windows, Siding and Commercial.

These operating segments follow the same accounting policies used for our consolidated financial statements. We evaluate a segment’s performance on a U.S. GAAP basis primarily upon operating income before corporate expenses.

Corporate assets consist primarily of cash, investments, prepaid expenses, current and deferred taxes and property, plant and equipment associated with our headquarters in Cary, North Carolina and office in Houston, Texas. These items (and income and expenses related to these items) are not allocated to the operating segments. Corporate unallocated expenses primarily include share-based compensation expenses, restructuring charges, acquisition-related costs, and other expenses related to executive, legal, finance, tax, treasury, human resources, information technology and strategic sourcing, and corporate travel expenses. Additional unallocated amounts primarily include non-operating items such as interest income, interest expense, loss on extinguishment of debt and other income (expense).

The following table represents summary financial data attributable to the segments for the periods indicated (in thousands):

NOTE 21 — CONTINGENCIES

As a manufacturer of products primarily for use in building construction, the Company is inherently exposed to various types of contingent claims, both asserted and unasserted, in the ordinary course of business. As a result, from time to time, the Company and/or its subsidiaries become involved in various legal proceedings or other contingent matters arising from claims or potential claims arising out of its operations and businesses that cover a wide range of matters, including, among others, environmental, contract, employment, intellectual property, securities, personal injury, property damage, product liability, warranty, and modification, adjustment or replacement of component parts or units sold, which may include product recalls. The Company insures (or self insures) against these risks to the extent deemed prudent by its management and to the extent insurance is available. The Company regularly reviews the status of ongoing proceedings and other contingent matters along with legal counsel. Liabilities for such items are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably estimated. Liabilities are adjusted when additional information becomes available. Management believes that the ultimate disposition of these matters will not have a material adverse effect on the Company’s results of operations, financial position or cash flows. However, such matters are subject to many uncertainties and outcomes and are not predictable with assurance.

Further, due to the lack of adequate information and the potential impact of present regulations and any future regulations, there are certain circumstances in which no range of potential exposure may be reasonably estimated. Also, it is not possible to ascertain the ultimate legal and financial liability with respect to certain contingent liabilities, including lawsuits, and therefore no such estimate has been made as of July 3, 2021.

Environmental

The Company’s operations are subject to various federal, state, local and foreign environmental, health and safety laws. Among other things, these laws regulate the emissions or discharge of materials into the environment; govern the use, storage, treatment, disposal and management of hazardous substances and wastes; protect the health and safety of its employees and the end-users of its products; regulate the materials used in its products; and impose liability for the costs of investigating and remediating (as well as other damages resulting from) present and past releases of hazardous substances. Violations of these laws or of any conditions contained in environmental permits could result in substantial fines or penalties, injunctive relief, consent orders, requirements to install pollution controls or other abatement equipment, or civil sanctions.

The Company could be held liable for costs to investigate, remediate or otherwise address contamination at any real property it has ever owned, operated or used as a disposal site, or at other sites where we or predecessors may have released hazardous materials. The Company could incur fines, penalties or sanctions or be subject to third-party claims, including indemnification claims, for property damage, personal injury or otherwise as a result of violations of (or liabilities under) environmental, health and safety laws, or in connection with releases of hazardous or other materials.

MW Manufacturers Inc. (“MW”), a subsidiary of Ply Gem Industries, Inc., entered into a September 2011 Administrative Order on Consent with the EPA under the Corrective Action Program to address known releases of hazardous substances at MW’s Rocky Mount, Virginia property. A Phase I RCRA Facility Investigation (“RFI”) was submitted to the Virginia Department of Environmental Quality (“VDEQ”) in December 2015, and a Phase II RFI and the Human Health Risk Assessment and Baseline Ecological Risk Assessment were submitted in October 2018. A Limited Corrective Measures Study (“LCMS”) based on the investigations was submitted to the VDEQ for review and approval in September 2019. The VDEQ concurred with the LCMS and prepared a Statement of Basis, which was published for a 30-day public review and comment in April 2021. Upon completion, the VDEQ issued its Final Decision and Response to Comments on May 19, 2021 to approve the final remedy proposed in the LCMS. The Company has recorded a liability of $4.5 million for this MW site, of which $1.0 million is in other current liabilities in the Company’s consolidated balance sheet as of July 3, 2021. 

The EPA is investigating groundwater contamination at a Superfund site in York, Nebraska, referred to as the PCE/TCE Northeast Contamination Site (“PCE/TCE Site”). Kroy Building Products, Inc. (“KBP”), a subsidiary of Ply Gem Industries, Inc., has been identified as a potentially responsible party (“PRP”) at the site and has liability for investigation and remediation costs associated with the contamination. On May 17, 2019, KBP and an unrelated respondent, Kroy Industries, Inc., entered into an Administrative Settlement Agreement and Order on Consent with the EPA to conduct a Remedial Investigation/Feasibility Study (“RI/FS”) of the PCE/TCE Site. A final RI/FS Work Plan was submitted to EPA in November 2019 and approved in December 2019. RI Phase I field sampling and mobile laboratory analysis was initiated in Spring 2020. After a delay due to the COVID-19 pandemic, Phase 2 of the R1 Phase field work was completed in May 2021, and results are being analyzed to determine scope of additional investigation. The Company has recorded a liability of $4.4 million within other current liabilities in its consolidated balance sheet as of July 3, 2021. The Company will adjust our remediation liability in future periods, if necessary, as the RI/FS progresses or if additional requirements are imposed. The Company may be able to recover a portion of costs incurred in connection with the PCE/TCE Site from other potentially responsible parties, though there is no assurance we would receive any funds.

32

Based on current information, the Company is not aware of any environmental compliance obligations, claims or investigations that will have a material adverse effect on its results of operations, cash flows or financial position except as otherwise disclosed in the Company’s consolidated financial statements. However, there can be no guarantee that previously known or newly discovered matters will not result in material costs or liabilities.

Litigation

The Company believes it has valid defenses to the outstanding claims discussed below and will vigorously defend all such claims; however, litigation is subject to many uncertainties and there cannot be any assurance that the Company will ultimately prevail or, in the event of an unfavorable outcome or settlement of litigation, that the ultimate liability would not be material and would not have a material adverse effect on the business, results of operations, cash flows or financial position of the Company.

In November 2018, Aurora Plastics, LLC (“Aurora”) initiated an arbitration demand against Atrium Windows and Doors, Inc., Atrium Extrusion Systems, Inc., and North Star Manufacturing (London) Ltd. (collectively, “Atrium”) pursuant to a Third Amended and Restated Vinyl Compound and Supply Agreement dated as of December 22, 2016. A settlement was reached in this case during the fourth quarter of 2019. The Company has a $3.9 million liability related to the settlement, of which $2.3 million is in other current liabilities in the Company’s consolidated balance sheet as of July 3, 2021.

On November 14, 2018, an individual stockholder, Gary D. Voigt, filed a putative class action Complaint in the Delaware Court of Chancery against Clayton Dubilier & Rice, LLC (“CD&R”), Clayton, Dubilier & Rice Fund VIII, L.P. (“CD&R Fund VIII”), and certain directors of the Company. Voigt purports to assert claims on behalf of himself, on behalf of a class of other similarly situated stockholders of the Company, and derivatively on behalf of the Company, the nominal defendant. An Amended Complaint was filed on April 11, 2019. The Amended Complaint asserts claims for breach of fiduciary duty and unjust enrichment against CD&R Fund VIII and CD&R, and for breach of fiduciary duty against twelve director defendants in connection with the Merger. Defendants moved to dismiss the Amended Complaint and, on February 10, 2020, the court denied the motions except as to four of the director defendants. Voigt seeks damages in an amount to be determined at trial.

Other contingencies

The Company’s imports of fabricated structural steel (“FSS”) from its Mexican affiliate, Building Systems de Mexico S.A. de C.V. (“BSM”) were subject to antidumping (“AD”) and countervailing duty (“CVD”) tariff proceedings before the U.S. Department of Commerce (“DOC”) and the U.S. International Trade Commission (“USITC”). The proceedings were initiated in February 2019 by the American Institute of Steel Construction against FSS being imported into the USA from Mexico, Canada, and China. In 2019, the DOC issued preliminary tariff rates and in 2020 finalized CVD and AD tariff rates of 0% and 8.47%, respectively, for the Company’s imports of FSS from BSM. However, in February 2020, in a 3 to 2 vote, the USITC concluded there was no injury or threat of injury to the domestic FSS industry. In March 2020 the USITC opinion was published in the Federal Register, ceasing the Company’s requirement to pay the AD and CVD tariffs. The Company received full reimbursement for the $4.1 million in tariffs previously deposited with United States Customs and Border Protection and recorded a reduction in costs of sales during the fiscal year ended December 31, 2020. This matter has been appealed and the Company will continue to vigorously advocate its position that its import of FSS from BSM should not be subject to any CVD or AD tariffs.

NOTE 22 — SUBSEQUENT EVENTS

On July 30, 2021, the Company entered into an agreement to acquire Cascade Windows for $245 million in cash, subject to customary adjustments. We expect the transaction to close during the third quarter of 2021, subject to regulatory approval and the satisfaction of customary closing conditions. Cascade Windows serves the residential new construction and repair and remodel markets with energy efficient vinyl window and door products from various manufacturing facilities in the United States, expanding our manufacturing capabilities and creating new opportunities for us in the Western United States. We anticipate funding the acquisition with cash available on the balance sheet. The Company expects Cascade Window’s results to be reported within the Windows segment.

OVERVIEW

Cornerstone Building Brands, Inc. is the largest manufacturer of exterior building products in North America. The Company serves residential and commercial customers across new construction and the repair and remodel markets. Our mission is to be relentlessly committed to our customers and to create great building solutions that enable communities to grow and thrive.

We have developed and continue to implement a well-defined business strategy focused on: (i) driving profitable growth in new and existing markets; (ii) leveraging operational excellence across our businesses; (iii) implementing a capital allocation

35

framework balanced between a focus on opportunistic investment in high return initiatives and continued debt repayment; and (iv) operating every part of our business with an ongoing commitment to sustainability.

We believe that by focusing on operational excellence every day, creating a platform for future growth and investing in market-leading residential and commercial building brands, we will deliver unparalleled financial results. We design, engineer, manufacture, install and market external building products through our three operating segments: Windows, Siding, and Commercial.

Our manufacturing processes are vertically integrated, which we believe provides cost and competitive advantages. As the leading manufacturer of vinyl windows, vinyl siding, insulated metal panels, metal roofing and wall systems and metal accessories, Cornerstone Building Brands combines a diverse portfolio of products with an expansive national footprint that includes over 20,000 employees at manufacturing, distribution and office locations primarily in North America.

At Cornerstone Building Brands, corporate stewardship is a responsibility that is deeply embedded. Our sustainable business practices have given us the staying power to make a real difference in countless cities and neighborhoods.

Our sales and earnings are subject to both seasonal and cyclical trends and are influenced by general economic conditions, interest rates, the price of material costs relative to other building materials, the level of residential and nonresidential construction activity, repair and remodel demand and the availability and cost of financing for construction projects. Our sales normally are lower in the first and fourth fiscal quarters of each year compared to the second and third fiscal quarters because of unfavorable weather conditions for construction and typical business planning cycles affecting construction.

Markets We Serve

Our products are available across several large and attractive end markets, including residential new construction, repair and remodel and low-rise non-residential construction. We believe that there are favorable underlying fundamental factors that will drive long-term growth across the end markets in which we operate. We also believe that the ongoing COVID-19 pandemic, while still causing economic uncertainty worldwide, has driven strong demand for residential repair and remodel activity, residential new construction and select segments of the low-rise non-residential construction market, such as distribution, warehouse, healthcare and educational facilities in suburban regions; however, the COVID-19 pandemic has also caused challenges in other areas of non-residential construction, most notably in retail and commercial office facilities in densely populated urban centers, where we have minimal, if any, participation. We believe our business is well-positioned to benefit from broader societal and population trends favoring suburban regions, as employment and living preferences shift towards such regions.

Cornerstone Building Brands is deeply committed to the communities where our customers and employees live, work and play. We recognize that our customers are increasingly environmentally conscious in their purchasing behavior, and we believe our sustainable solutions favorably address these evolving consumer preferences. For example, certain products in our portfolio are high in recycled end content, virtually 100% recyclable at the end of their useful life and often manufactured to meet or exceed specified sustainability targets, such as ENERGY STAR and LEED certifications. We recognize that efficient use of recycled materials helps to conserve natural resources and reduces environmental impact, and we are committed to driving these sustainable practices throughout our business.

COVID-19 Update

We experienced an overall decrease in customer demand across all our markets during 2020 as the COVID-19 pandemic caused temporary closures of non-life sustaining businesses and delayed construction activity. Throughout this pandemic, the Company has been adhering to mandates and other guidance from local governments and health authorities as well as taken extraordinary measures and invested significantly in practices to protect the health and safety of our employees and our communities. During 2020, the Company quickly implemented a range of actions aimed at reducing costs and preserving liquidity. These actions included plant closures, permanent workforce reductions, employee furloughs, a hiring freeze, a deferral of annual wage raises, and reducing discretionary and non-essential expenses, such as consulting expenses. Additionally, we reduced capital expenditures to focus on key strategic initiatives, such as automation, product innovation, and critical maintenance items. We believe our business model, our existing balances of domestic cash and cash equivalents, availability under our revolving credit facilities, currently anticipated operating cash flows, and overall liquidity will be sufficient to meet our cash needs arising in the ordinary course of business for the next twelve months. We will continue to evaluate the nature and extent of the COVID-19 pandemic’s impact on our financial condition, results of operations and cash flows.

RESULTS OF OPERATIONS

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

	Three Months Ended									Six Months Ended
(Amounts in thousands)	July 3, 2021			July 4, 2020			$ change	% change		July 3, 2021			July 4, 2020			$ change	% change

Strategic development and acquisition related costs	(61)			784			(845)	(107.8)	%	3,252			5,641			(2,389)	(42.4)	%
Interest expense	47,458			52,384			(4,926)	(9.4)	%	103,957			107,219			(3,262)	(3.0)	%
Net income (loss)	8,927			26,899			(17,972)	(66.8)	%	7,272			(515,174)			522,446	(101.4)	%

Net sales - Consolidated net sales for the three and six months ended July 3, 2021 increased by approximately 29.1% and 21.3%, respectively, as compared to the same period last year. The net sales growth was driven by improved volume of 13.4% and price actions in response to rising commodity costs and other inflationary impacts. Strong demand for residential products sold through the Windows and Siding segments was 18.2% higher than last year, while demand for non-residential improved approximately 3.6%.

For the first half of 2021, net sales grew 21.3% as compared to the same period last year with approximately 55% of the increase driven by strong demand within the Windows and Siding segments coupled with higher price realization.

Gross profit % of net sales - The Company’s gross profit percentage was 22.3% and 21.4% for the three and six months ended July 3, 2021, respectively, which was a 120 and 70 basis point decline over the three and six months ended July 4, 2020, respectively. As a result of the quick pace of recovery experienced across many end-markets, there has been a rapid rise in raw materials and many other manufacturing input costs. While we have responded by remaining disciplined with price leadership, the timing delay between when costs were incurred and when the price increase was realized compressed margins. Additionally, the pace and length of time we remain in an inflationary environment can have the effect of reducing gross profit margins. We remain focused on structurally improving our highly variable cost structure with cost savings initiatives. Also contributing to the lower gross profit as a % of net sales are higher manufacturing costs incurred to serve customers. These costs include increased freight, labor, and maintenance expenses.

Selling, general, and administrative expenses increased 21.7% and 5.8% during the three and six months ended July 3, 2021, respectively, compared to the three and six months ended July 4, 2020. The increase was primarily driven by return of near-term costs, such as variable compensation, IT and professional services, to support market recovery and further growth. Additionally, selling, general, and administrative expenses at July 4, 2020 included near-term cost savings initiatives executed in response to the COVID-19 pandemic.

Restructuring and impairment charges, net decreased $10.8 million and $22.8 million during the three and six months ended July 3, 2021, respectively, compared to the three and six months ended July 4, 2020, primarily due to completion of operational and organizational actions taken in response to the COVID-19 pandemic.

Strategic development and acquisition related costs decreased $0.8 million and $2.4 million during the three and six months ended July 3, 2021, respectively, compared to the three and six months ended July 4, 2020, due to the timing of these activities, primarily acquisition related.

Interest expense decreased $4.9 million or 9.4% and $3.3 million or 3.0% in the three and six months ended July 3, 2021, respectively, as compared to the three and six months ended July 4, 2020, primarily as a result of the redemption of the $645 million 8.00% Senior Notes coupled with the refinancing of the Current Term Loan Facility.

Consolidated provision (benefit) for income taxes was a benefit of $1.1 million and $0.3 million for the three and six months ended July 3, 2021, respectively, compared to a benefit of $17.3 million and $35.3 million for the three and six months ended July 4, 2020, respectively. The effective tax rate for the three and six months ended July 3, 2021 was (13.5)% and (3.9)%, respectively, compared to (181.2)% and 6.4% for the three and six months ended July 4, 2020, respectively. The change

37

in the effective tax rate was primarily driven by the improved financial results for the three and six months ended July 3, 2021, in addition to the impact associated with the goodwill impairment recorded during the three months ended April 4, 2020.

Net income (loss) was $8.9 million or $0.07 per diluted share and $7.3 million or $0.06 per diluted share for the three and six months ended July 3, 2021, respectively.

We continue to experience positive momentum from residential single-family and repair and remodel end-markets due to demand and historic backlog levels. Single family housing starts were on a historic pace before construction delays and stoppage due to the COVID-19 pandemic. Housing starts have rebounded above prior levels and are expected to grow for the next couple of years. We are experiencing historic backlog levels from the improving non-residential end-markets as the Architecture Billings Index (“ABI”) increases. In the current marketplace, we continue to face significant raw material and labor inflation.

Segment Results of Operations

We report our segment information in the same way management internally organizes the business in assessing performance and making decisions regarding allocation of resources in accordance with ASC 280, Segment Reporting. We have determined that we have three reportable segments, organized and managed principally by the different industry sectors they serve. While the segments often operate using shared infrastructure, each reportable segment is managed to address specific customer needs in these diverse market sectors. We report all other business activities in Corporate and unallocated costs. Corporate assets consist primarily of cash, investments, prepaid expenses, current and deferred taxes and property, plant and equipment associated with our headquarters in Cary, North Carolina and office in Houston, Texas. These items (and income and expenses related to these items) are not allocated to the operating segments. Corporate unallocated expenses primarily include share-based compensation expenses, restructuring charges, acquisition costs, and other expenses related to executive, legal, finance, tax, treasury, human resources, information technology and strategic sourcing, and corporate travel expenses. Additional unallocated amounts primarily include non-operating items such as interest income, interest expense and other income (expense).

One of the primary measurements used by management to measure the financial performance of each segment is Adjusted EBITDA, a non-GAAP financial measure. We define Adjusted EBITDA as net income (loss), adjusted for the following items: income tax (benefit) expense; depreciation and amortization; interest expense, net; restructuring and impairment charges; acquisition costs; non-cash charges; goodwill impairment; share-based compensation expense; non-cash foreign exchange transaction/translation (income) loss; other non-cash items; and other items.

The presentation of segment results below includes a reconciliation of the changes for each segment reported in accordance with U.S. GAAP to a pro forma basis to allow investors and the Company to meaningfully evaluate the percentage change on a comparable basis from period to period. The pro forma financial information is based on the historical information of Cornerstone, Prime Windows LLC (“Prime Windows”), which the Company acquired on April 30, 2021, and Kleary Masonry, Inc. (“Kleary”), which the Company acquired on March 2, 2020. The pro forma financial information does not give effect to the potential impact of current financial conditions, any anticipated synergies, operating efficiencies or cost savings that may result from the Prime Windows and Kleary acquisitions or any integration costs. Pro forma balances are not necessarily indicative of operating results had the Prime Windows and Kleary acquisitions occurred on January 1, 2020 or of future results.

See Note 20 — Segment Information in the notes to the unaudited consolidated financial statements for more information on our segments.

NON-GAAP FINANCIAL MEASURES

Set forth below are certain “non-GAAP financial measures” as defined under the Securities Exchange Act of 1934 and in accordance with Regulation G. Management believes the use of such non-GAAP financial measures assists investors in understanding the ongoing operating performance of the Company by presenting the financial results between periods on a more comparable basis. Such non-GAAP financial measures should not be construed as an alternative to reported results determined in accordance with U.S. GAAP. We have included reconciliations of these non-GAAP financial measures to the most directly comparable financial measures calculated and provided in accordance with U.S. GAAP.

Net sales for the three and six months ended July 3, 2021 were 23.4% and 10.8% higher than the same period a year ago, respectively, driven by disciplined price actions to mitigate rising steel costs. This combined with an increase in volume of 3.6% and flat volume of 0.1% respectively during the three and six months ended July 3, 2021 driven by strong demand despite supply constraints.

Operating income for the three months ended July 3, 2021 increased $16.7 million or 45.5% compared to the three months ended July 4, 2020, primarily due to realization of price actions taken to offset rising steel and other manufacturing costs coupled with higher volume from positive end-market demand offsetting return of near-term costs and manufacturing inefficiencies as a result of supply constraints. Operating income for the six months ended July 3, 2021 increased $41.4 million or 77.4% compared to the six months ended July 4, 2020, due to lower selling, general and administrative expenses, and lower restructuring and impairment charges, improved manufacturing efficiencies and structural cost, $5.4 million of a goodwill impairment incurred in the comparable period, favorable price/mix, net of inflation.

Adjusted EBITDA for the three months ended July 3, 2021 was $67.5 million or 14.7% of net sales, a decrease of 50 basis points from the same period a year ago primarily due to favorable price, net of commodity and other inflation impacts, partially offset by manufacturing inefficiencies caused by material constraints and labor shortages. On a year-to-date basis, net sales increased 10.8%, and Adjusted EBITDA margin increased 80 basis points.

LIQUIDITY AND CAPITAL RESOURCES

General

Our principal source of funds is cash generated from operations, supplemented by borrowings against our asset-based lending and revolving credit facility. We typically invest our excess cash in various overnight investments that are issued or guaranteed by the U.S. federal government. Our cash, cash equivalents and restricted cash decreased from $680.5 million as of December 31, 2020 to $95.2 million as of July 3, 2021. The following table summarizes our consolidated cash flows for the six months ended July 3, 2021 and July 4, 2020 (in thousands):

Cash, cash equivalents and restricted cash at end of period	$	95,202	$	489,720

Operating Activities

The Company used cash in operating activities during the six months ended July 3, 2021 to invest in working capital items to support strong market demand.

The following table shows the impact of working capital items on cash during the six months ended July 3, 2021 and July 4, 2020, respectively (in thousands):

	Six Months Ended
	July 3, 2021		July 4, 2020		$ Change
Net cash (used in) provided by:

Net cash (used in) provided by working capital items	$	(222,263)	$	4,210	$	(226,473)

The use of cash for working capital between periods was due to robust market demand across the segments coupled with aggressive price actions in response to rising commodity costs and other inflationary impacts. See the Consolidated Statements of Cash Flows in the unaudited consolidated financial statements for additional information.

Investing Activities

Net cash used in investing activities was $141.3 million during the six months ended July 3, 2021 compared to $89.3 million used in investing activities during the six months ended July 4, 2020. During the six months ended July 3, 2021, we paid approximately $94.4 million toward acquisitions and we used $47.6 million for capital expenditures. In the six months ended July 4, 2020, we paid approximately $41.8 million, net of cash acquired, for the acquisition of Kleary and used $47.6 million for capital expenditures.

Financing Activities

Net cash used in financing activities was $431.4 million during the six months ended July 3, 2021 compared to $410.3 million provided by financing activities in the six months ended July 4, 2020. During the six months ended July 3, 2021, we borrowed an additional $108.4 million on our Current Term Loan Facility, borrowed $160.0 million on our Current ABL Facility, paid $670.8 million to redeem the 8.00% Senior Notes and paid quarterly installments of $12.9 million on the Current Term Loan Facility.

43

During the six months ended July 4, 2020, we borrowed $40.0 million on our Current ABL Facility to finance the acquisition of Kleary, borrowed an additional $305.0 million on our Current ABL Facility and repaid $30.0 million of that amount, and $115.0 million on our Current Cash Flow Revolver to increase our cash position and preserve financial flexibility in light of uncertainty in the global markets resulting from the COVID-19 pandemic, paid $12.8 million on quarterly installments on our Current Term Loan Facility and used $6.4 million to repurchase shares of our outstanding common stock under our stock repurchase programs.

Debt

Below is a reconciliation of the Company’s net debt (in thousands) as of the dates indicated. Management considers net debt to be more representative of the Company’s financial position than total debt due to the amount of cash and cash equivalents held by the Company and the ability to utilize such cash and cash equivalents to reduce debt if needed.

Net Debt	$	3,164,522	$	2,968,712

On April 15, 2021, the Company fully redeemed its $645 million aggregate principal amount of 8.00% Senior Notes using available cash from the balance sheet and net proceeds from its extended and upsized senior term loan facility. The Company successfully upsized and extended the maturity of its $2,492 million senior term loan facility due 2025 in the form of $2,600 million in Tranche B term loans due April 12, 2028. Additionally, the Company amended and refinanced its senior cash flow based and asset-based revolving credit facilities, extending the maturities to April 12, 2026.

In connection with the new Tranche B term loans, the Company also terminated existing two interest rate swaps and entered into two new swaps maturing in April 2026 on an aggregate notional value of $1.5 billion. The interest rate swaps effectively convert a portion of the floating rate interest payment into a fixed rate interest payment.

We may not be successful in refinancing, extending the maturity or otherwise amending the terms of our outstanding indebtedness in the future because of market conditions, disruptions in the debt markets, our financial performance or other reasons. Furthermore, the terms of any refinancing, extension or amendment may not be as favorable as the current terms of our indebtedness. If we are not successful in refinancing our indebtedness or extending its maturity, we and our subsidiaries could face substantial liquidity problems and may be forced to reduce or delay capital expenditures, sell assets, seek additional capital or restructure our indebtedness.

For additional information, see Note 14 — Long-Term Debt and Note 15 — Derivatives in the notes to the unaudited consolidated financial statements.

Additional Liquidity Considerations

We periodically evaluate our liquidity requirements, capital needs and availability of resources in view of inventory levels, expansion plans, debt service requirements and other operating cash needs. To meet our short-term and long-term liquidity requirements, including payment of operating expenses and repayment of debt, we rely primarily on cash from operations. The following table summarizes key liquidity measures under the Current ABL Credit Agreement and the Current Cash Flow Credit Agreement in effect as of July 3, 2021 and December 31, 2020 (in thousands):

	July 3, 2021		December 31, 2020

We expect to contribute $3.2 million to the defined benefit plans and $0.7 million to the postretirement medical and life insurance plans in the year ending December 31, 2021.

On April 15, 2021, the Company fully redeemed its $645 million aggregate principal amount of 8.00% Senior Notes using available cash from the balance sheet and net proceeds from its extended and upsized senior term loan facility, which reduced total liquidity. We expect that cash generated from operations and our availability under the ABL Credit Facility and Current Cash Flow Revolver will be sufficient to provide us the ability to fund our operations and to provide the increased working capital necessary to support our strategy and fund planned capital expenditures for fiscal 2021 and expansion when needed. The Company expects total capital expenditures to be approximately 2.0% to 2.5% of net sales during fiscal 2021.

Consistent with our growth strategy, we evaluate potential acquisitions that would provide additional synergies in our Windows, Siding and Commercial segments. From time to time, we may enter into letters of intent or agreements to acquire assets or companies in these business lines. The consummation of these transactions could require substantial cash payments and/or issuance of additional debt.

On April 30, 2021, the Company acquired Prime Windows. Prime Windows serves residential new construction and repair and remodel markets with energy efficient vinyl window and door products from two manufacturing facilities in the United States, expanding our manufacturing capabilities and creating new opportunities for us in the Western United States. This acquisition was funded through borrowings under the Company’s existing credit facilities.

On July 30, 2021, the Company entered into an agreement to acquire Cascade Windows. We expect the transaction to close during the third quarter of 2021, subject to regulatory approval and the satisfaction of customary closing conditions. Cascade Windows serves the residential new construction and repair and remodel markets with energy efficient vinyl window and door products from various manufacturing facilities in the United States, expanding our manufacturing capabilities and creating new opportunities for us in the Western United States. We anticipate funding the acquisition with cash available on the balance sheet.

We also evaluate from time-to-time possible dispositions of assets or businesses when such assets or businesses are no longer core to our operations and do not fit into our long-term strategy.

On June 7, 2021, the Company announced that it has entered into a definitive agreement to sell its insulated metal panels (“IMP”) business to Nucor Insulated Panel Group Inc and certain of its subsidiaries (collectively, “Nucor”) in a cash transaction for $1 billion. The IMP transaction includes products sold under the Metl-Span and CENTRIA brands. On July 27, 2021, the Company announced that it has entered into a definitive agreement to sell its roll-up sheet door business to Janus International Group, Inc. (“Janus”) in a cash transaction for $168 million. The roll-up sheet door transaction includes products sold under the DBCI brand. Both transactions are expected to close in the second-half of 2021, subject to regulatory approval and other customary closing conditions. The Company expects post-tax proceeds of approximately $875 million from these transactions to be used to pay down a portion of its secured credit facilities, invest in organic growth and efficiency projects, and make strategic acquisitions.

From time to time, we have used available funds to repurchase shares of our common stock under our stock repurchase programs. On March 7, 2018, we announced that our Board of Directors authorized a new stock repurchase program for the repurchase of up to an aggregate of $50.0 million of our outstanding Common Stock. Under this repurchase programs, we are authorized to repurchase shares, if at all, at times and in amounts that we deem appropriate in accordance with all applicable securities laws and regulations. Shares repurchased are usually retired. There is no time limit on the duration of the program. During the six months ended July 3, 2021, there were no stock repurchases under the stock repurchase program. As of July 3, 2021, approximately $49.1 million remained available for stock repurchases under the program announced on March 7, 2018. In addition to repurchases of shares of our common stock under our stock repurchase program, we also withhold shares of

45

restricted stock to satisfy minimum tax withholding obligations arising in connection with the vesting of share-based compensation.

We may from time to time take steps to reduce our debt or otherwise improve our financial position. These actions could include prepayments, open market debt repurchases, negotiated repurchases, other redemptions or retirements of outstanding debt, opportunistic refinancing of debt and raising additional capital. The amount of prepayments or the amount of debt that may be refinanced, repurchased or otherwise retired, if any, will depend on market conditions, trading levels of our debt, our cash position, compliance with debt covenants and other considerations. Our affiliates may also purchase our debt from time to time through open market purchases or other transactions. In such cases, our debt may not be retired, in which case we would continue to pay interest in accordance with the terms of the debt, and we would continue to reflect the debt as outstanding on our consolidated balance sheets.

OFF-BALANCE SHEET ARRANGEMENTS

As part of our ongoing business, we do not participate in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities (“SPEs”), which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As of July 3, 2021, we were not involved in any material unconsolidated SPE transactions.

CONTRACTUAL OBLIGATIONS

Our contractual obligations principally include obligations associated with our outstanding indebtedness, operating lease obligations and inventory purchase commitments. Contractual obligations did not materially change during the six months ended July 3, 2021, except for debt related activities as disclosed in Note 14 — Long-Term Debt in the notes to the unaudited consolidated financial statements and in Liquidity and Capital Resources — Financing Activities, and lease activity as disclosed in Note 9 — Leases in the notes to the unaudited consolidated financial statements.

CRITICAL ACCOUNTING POLICIES 

Critical accounting policies are those that are most important to the portrayal of our financial position and results of operations. These policies require our most subjective judgments, often employing the use of estimates about the effect of matters that are inherently uncertain. Our most critical accounting policies include those that pertain to accounting for acquisitions, intangible assets and goodwill; warranty; and income taxes, which are described in Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

RECENT ACCOUNTING PRONOUNCEMENTS

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Windows and Siding Businesses

We are subject to market risk with respect to the pricing of our principal raw materials, which include PVC resin, aluminum and glass. If prices of these raw materials were to increase dramatically, we may not be able to pass such increases on to our customers and, as a result, gross margins could decline significantly. We manage the exposure to commodity pricing risk by increasing our selling prices for corresponding material cost increases, continuing to diversify our product mix, strategic buying programs and vendor partnering. The average market price for PVC resin was estimated to have increased approximately 57.6% for the six months ended July 3, 2021 compared to the six months ended July 4, 2020.

Commercial Business

We are subject to market risk exposure principally related to volatility in the price of steel. For the six months ended July 3, 2021, material costs (predominantly steel costs) constituted approximately 64% of our Commercial segment’s cost of sales. Our business is heavily dependent on the price and supply of steel. Our various products are fabricated from steel produced by mills to forms including bars, plates, structural shapes, sheets, hot-rolled coils and galvanized or Galvalume® — coated coils (Galvalume® is a registered trademark of BIEC International, Inc.). The steel industry is highly cyclical in nature, and steel prices have been volatile in recent years and may remain volatile in the future. Steel prices are influenced by numerous factors beyond our control, including general economic conditions, domestically and internationally, the availability of raw materials, competition, labor costs, freight and transportation costs, production costs, import duties and other trade restrictions. Based on the cyclical nature of the steel industry, we expect steel prices will continue to be volatile.

With material costs (predominantly steel costs) accounting for approximately 64% of our Commercial segment's cost of sales for the six months ended July 3, 2021, a one percent change in the cost of steel could have resulted in a pre-tax impact on cost of sales of approximately $4.3 million for our six months ended July 3, 2021. The impact to our financial results of operations of such an increase would be significantly dependent on the competitive environment and the costs of other alternative building products, which could impact our ability to pass on these higher costs.

Other Commodity Risks

In addition to market risk exposure related to the volatility in the price of steel, aluminum, PVC resin, and glass, we are subject to market risk exposure related to volatility in the price of natural gas. As a result, we occasionally enter into both index-priced and fixed-price contracts for the purchase of natural gas. We have evaluated these contracts to determine whether the contracts are derivative instruments. Certain contracts that meet the criteria for characterization as a derivative instrument may be exempted from hedge accounting treatment as normal purchases and normal sales and, therefore, these forward contracts are not marked to market. At July 3, 2021, all of our forward contracts for commodities met the scope exemption for normal purchases and normal sales.

Interest Rates

We are subject to market risk exposure related to changes in interest rates on our Current Cash Flow Facilities and Current ABL Facility, which provides for borrowings of up to $2,715.0 million on the Current Cash Flow Facilities and up to $611.0 million on the Current ABL Facility. These instruments bear interest at an agreed upon percentage point spread from either LIBOR or an alternate base rate. Assuming the Current Cash Flow Revolver is fully drawn, each quarter point increase or decrease in the interest rate would change our interest expense by approximately $6.8 million per year for the Current Cash Flow Facilities. Assuming the Current ABL Facility is fully drawn, each quarter point increase or decrease in the interest rate would change our interest expense by approximately $1.5 million per year. The fair value of our term loan credit facility at July 3, 2021 and December 31, 2020 was approximately $2,589.6 million and $2,485.5 million, respectively, compared to a face value of approximately $2,593.5 million and $2,498.0 million, respectively. In April 2021, we entered into cash flow interest rate swap hedge contracts for $1.5 billion to mitigate the exposure risk of our floating interest rate debt. The interest rate swaps effectively convert a portion of the floating rate interest payment into a fixed rate payment. As of July 3, 2021, our cash flow hedge contracts had a fair value liability of $86.5 million and are recorded as a non-current liability on our consolidated balance sheet.

See Note 14 — Long-Term Debt and Note 15 — Derivatives in the notes to the unaudited consolidated financial statements for information on the material terms of our long-term debt and interest rate swaps.

Foreign Currency Exchange Rates

We are exposed to the effect of exchange rate fluctuations on the U.S. dollar value of foreign currency denominated operating revenue and expenses.

The functional currency for our Canada operations is the Canadian dollar. Translation adjustments resulting from translating the functional currency financial statements into U.S. dollar equivalents are reported separately in accumulated other

47

comprehensive income (loss) in stockholders’ equity. The net foreign currency exchange gain (loss) included in net income (loss) for the three and six months ended July 3, 2021 was $38 thousand and $0.3 million, respectively; and $1.7 million and $(1.4) million for the three and six months ended July 4, 2020, respectively. Net foreign currency translation adjustment, net of tax, and included in other comprehensive income (loss) for the three and six months ended July 3, 2021 was $4.6 million and $10.7 million, respectively; and was $8.6 million and $(1.0) million for the three and six months ended July 4, 2020, respectively.

The functional currency for our Mexico operations is the U.S. dollar. Adjustments resulting from the re-measurement of the local currency financial statements into the U.S. dollar functional currency, which uses a combination of current and historical exchange rates, are included in net income (loss) in the current period. Net foreign currency re-measurement gain (loss) was $0.2 million and $(0.1) million for the three and six months ended July 3, 2021, respectively; and $0.4 million and $(0.6) million for the three and six months ended July 4, 2020, respectively.

We have entered into currency forward contracts with a financial institution through May 2022 to hedge primarily inventory purchases in Canada of approximately $57.5 million in the aggregate at fixed USD/CAD rates ranging from 1.2120 to 1.2726. In the future, we may enter into additional currency hedging contracts, to further mitigate the exposure risk of currency fluctuation against the Canadian dollar and/or the Mexican peso. See Note 15 — Derivatives in the notes to the unaudited consolidated financial statements for information on our currency hedges.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of July 3, 2021. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding the required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Management believes that our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives and based on the evaluation of our disclosure controls and procedures as of July 3, 2021, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at such reasonable assurance level. 

Internal Control over Financial Reporting

We are currently in the process of assessing the internal controls of Prime Windows LLC (“Prime Windows”) as part of the post-close integration process. Prime Windows has been excluded from our assessment of internal control over financial reporting as of July 3, 2021. The total assets and revenues excluded from management’s assessment represent 0.1% and 0.5%, respectively, of the consolidated financial statements as of and for the six months ended July 3, 2021.

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended July 3, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On March 7, 2018, the Company announced that its Board of Directors authorized a stock repurchase program for up to an aggregate of $50.0 million of the Company’s Common Stock. Under this repurchase program, the Company is authorized to repurchase shares at times and in amounts that we deem appropriate in accordance with all applicable securities laws and regulations. Shares repurchased are usually retired. There is no time limit on the duration of the program.

During the second quarter of fiscal 2021, there were no stock repurchases under the program. At July 3, 2021, approximately $49.1 million remained available for stock repurchases under the program.

R E C I T A L S:

Article 1

Transfer ofEquity Interests and Canada Transferred Assets and Assumption of Canada Assumed Liabilities

Section 1.1     Closing. The closing of the sale and purchase of the Equity Interests and Canada Transferred Assets and the assignment and assumption of the Canada Assumed Liabilities (the “Closing”) shall take place at the offices of Debevoise & Plimpton LLP, 919 Third Avenue, New York, New York 10022 or at such other place as the parties shall mutually agree, at 10:00 a.m. on the date that is three (3) Business Days after the conditions set forth in Article 6 have been satisfied or waived (other than those conditions which by their nature are to be satisfied at the Closing but subject to the satisfaction or waiver of those conditions at such time), unless another time, date or place is agreed to in writing by the parties, provided that the transfer of the Canada Transferred Assets and the assignment and assumption of the Canada Assumed Liabilities to Canada Buyer shall each occur immediately following the transfer of the Equity Interests. The date on which the Closing actually occurs is referred to hereinafter as the “Closing Date”. At the Closing:

(a)Transfer of Equity Interests and Canada Transferred Assets and Assumption of Canada Assumed Liabilities. Seller shall, sell, convey, assign, transfer, grant and deliver, or cause to be sold, conveyed, assigned, transferred, granted and delivered, (i) to Buyer all of the Equity Interests, free and clear of all Liens, other than Liens arising under applicable securities Laws, and (ii) to Canada Buyer, the Canada Transferred Assets free and clear of all Liens, other than Permitted Liens, and Canada Buyer shall assume the Canada Assumed Liabilities and cause all such Canada Assumed Liabilities to be paid, performed and discharged when due, without further recourse to Seller or its Affiliates.

2

(b)Estimated Purchase Price. Buyer shall pay Seller or other Persons designated by Seller, by wire transfer of immediately available funds to such account(s) as Seller shall designate in writing to Buyer not less than two (2) Business Days prior to the Closing Date (the “Seller Designated Account(s)”), an aggregate amount in cash equal to the Estimated Purchase Price, provided that any payments made under this Agreement by Buyer with respect to the Canada Transferred Assets shall be made on behalf of Canada Buyer and may, at the election of Buyer and Canada Buyer, be made directly by Canada Buyer.

(c)Indebtedness. Seller shall arrange for the Company, the Transferred Assets and the Canada Transferred Assets to be released, prior to or at the Closing, from all guarantee and collateral obligations under the Credit Facilities and any other Indebtedness of Seller or its Subsidiaries (other than the Company), pursuant to customary documentation (including obligations to fully release any Liens relating thereto) reasonably acceptable to Buyer, such that the Transferred Assets and Canada Transferred Assets are free and clear of any Liens other than Permitted Liens at Closing.

(d)Transaction Expenses. Simultaneously with Closing, Buyer shall pay, or cause to be paid, on behalf of Seller and its Affiliates (including the Company), as applicable, the Transaction Expenses (based on the estimates provided by Seller pursuant to Section 1.2(b)) by wire transfer of immediately available funds as directed by Seller.

Section 1.2    Purchase Price.

(a)Final Purchase Price. The aggregate consideration for the Equity Interests and Canada Transferred Assets shall be (x) an amount in cash equal to (i) the Enterprise Value, plus (ii) the Final Closing Date Cash, minus (iii) the Final Closing Date Indebtedness, plus (iv) the Final Net Working Capital Adjustment Amount (which may be a positive or negative number), minus (v) the Final Transaction Expenses (the calculation resulting from clauses (i), (ii), (iii), (iv) and (v), the “Final Purchase Price”) and (y) the assumption by Canada Buyer of the Canada Assumed Liabilities. Buyer shall prepare and deliver to Seller a statement allocating the Final Purchase Price between the aggregated Transferred Assets (other than the Canada Transferred Assets) (the “U.S. Purchase Price”) and the aggregated Canada Transferred Assets (the “Canadian Purchase Price”), which in the case of the U.S. Purchase Price shall include the Assumed Liabilities and in the case of the Canadian Purchase Price shall include the Canada Assumed Liabilities.

(b)Estimated Purchase Price. Beginning no later than five (5) Business Days prior to the Closing Date, or such other time as Buyer and Seller may mutually agree, Buyer and Seller, or their designated representatives, shall reasonably cooperate to jointly conduct a physical count and tally of the finished products, raw materials and supplies of the Company or attributable to the Transferred Assets (the “Inventory” and such count and tally, the “Inventory Count”) of the Company or attributable to the Transferred Assets (which for the avoidance of doubt, shall include amounts attributable to the Canada Transferred Assets) and shall use commercially reasonably efforts to jointly agree on a valuation (the “Inventory Valuation”) of the same to be included in the Net Working

3

Capital Adjustment Amount, which physical count and tally shall be rolled forward to the Closing Date in order to determine the amount of the Inventory for the good-faith estimate of the Net Working Capital Adjustment Amount; provided that in no event shall such Inventory Count or the determination of the Inventory Valuation delay the date that the Closing would otherwise occur as contemplated by Section 1.1 hereof and if the parties are unable to agree in good faith on the Inventory Valuation, Seller’s good faith determination of the Inventory Valuation shall control for purposes of the Estimated Closing Statement. Such Inventory shall be valued in accordance with the Accounting Principles. No later than two (2) Business Days prior to the Closing Date, Seller shall provide to Buyer a statement (the “Estimated Closing Statement”) setting forth an estimate of the Final Purchase Price which shall be based upon (i) the Enterprise Value and (ii) good-faith estimates of the Closing Date Cash, the Closing Date Indebtedness, the Net Working Capital Adjustment Amount and the Transaction Expenses (the “Estimated Purchase Price”), in each case, delivered with reasonable supporting detail with respect to the calculation of such amounts.

(c)Post-Closing Adjustments.

(i)Post-Closing Adjustment. As soon as practicable, but no later than ninety (90) days after the Closing Date, Seller shall prepare and deliver to Buyer a statement setting forth Seller’s calculation of (A) the Closing Date Cash, (B) the Closing Date Indebtedness, (C) the Net Working Capital Adjustment Amount, (D) the Transaction Expenses and (E) based thereon, Buyer’s calculation of the Final Purchase Price (such calculations, collectively, the “Proposed Purchase Price Calculations”), together with reasonable supporting detail with respect to the calculation of such amounts (the “Closing Statement”).

(ii)Within forty-five (45) days of receipt of the Closing Statement, Buyer may provide written notice to Seller disputing all or a part of the Proposed Purchase Price Calculations (such notice, a “Purchase Price Dispute Notice”). If Buyer does not provide a Purchase Price Dispute Notice to Seller within such forty-five (45)-day period, then the parties agree that the Proposed Purchase Price Calculations set forth in the Closing Statement shall become final and binding on the parties hereto. If a Purchase Price Dispute Notice is provided to Seller within such forty-five (45)-day period, then Seller and Buyer shall use reasonable best efforts to resolve the disputed items during the thirty (30)-day period commencing on the date of Seller’s receipt of the Purchase Price Dispute Notice.

(iii)If Seller and Buyer do not agree upon a final resolution with respect to any disputed items within such thirty (30)-day period, then the remaining items in dispute shall be submitted immediately to KPMG, or, if such firm declines to be retained to resolve the dispute, another nationally recognized, independent accounting firm reasonably acceptable to Seller and Buyer (in either case, the “Accounting Firm”). The parties agree to instruct the Accounting Firm to render a determination of the applicable dispute within forty-five (45) days after referral of the matter to such Accounting Firm, which determination must be in writing and must set forth, in reasonable detail, the basis therefor. The terms of

4

appointment and engagement of the Accounting Firm shall be as agreed upon between Seller and Buyer, and any associated engagement fees shall be initially borne fifty percent (50%) by Seller and fifty percent (50%) by Buyer; provided that such fees shall ultimately be borne by Seller and Buyer in inverse proportion as they may prevail on matters resolved by the Accounting Firm, which proportionate allocations shall also be determined by the Accounting Firm at the time the determination of the Accounting Firm is rendered on the merits of the disputed items. Except as provided in the preceding sentence, all other costs and expenses incurred by the parties hereto in connection with resolving any dispute hereunder before the Accounting Firm shall be borne by the party incurring such cost and expense. In resolving the disputed items, the Accounting Firm (A) shall be bound by the terms of this Agreement, (B) may not assign a value to any item greater than the greatest value claimed for such item or less than the smallest value claimed for such item by either Seller or Buyer, (C) shall rely solely on the written submissions of the parties and shall not conduct an independent investigation, (D) shall limit its decision to such items as are in dispute and to only those adjustments as are necessary for the Proposed Purchase Price Calculations to comply with the provisions of this Agreement and (E) shall act as an expert and not as an arbitrator. Such determination of the Accounting Firm shall be conclusive and binding upon the parties hereto, absent fraud, bad faith or manifest mathematical error. No ex parte conferences, oral examinations, testimony, depositions, discovery or other form of evidence gathering or hearings shall be conducted or allowed; provided that at the Accounting Firm’s request, or as mutually agreed by Seller and Buyer, Seller and Buyer may meet with the Accounting Firm so long as representatives of both Seller and Buyer are present.

(iv)The parties agree that they will, and agree to cause their respective independent accountants and their respective Subsidiaries to, cooperate and assist in all commercially reasonable respects in the calculation of the Final Purchase Price and in the conduct of the review by the other party and its representatives or, if applicable, the Accounting Firm of any proposed calculations of the Final Purchase Price or the components thereof, including the making available, to the extent necessary, of books, records, work papers and personnel.

or as required for the performance of the Ancillary Agreements, all Excluded Confidential Information; provided that Seller and its Affiliates may disclose Business Confidential Information and Buyer and its Affiliates may disclose Excluded Confidential Information, in each case (A) to the extent requested or required under any Law, rule or regulation applicable to such party (including reports required to be filed by Seller under the Exchange Act) or (B) to their respective Affiliates and their and their respective Affiliates’ directors, offices, employees, agents and advisors (including auditors, legal counsel and insurance providers) who need to know such information and who are bound by obligations of confidentiality to the disclosing party or one of its Affiliates with respect to such information; provided, further, that, in the event of any such request or requirement, to the extent permitted by Law, the party requested or required to make such disclosure shall (x) give Buyer (in the case of Business Confidential Information) or Seller (in the case of Excluded Confidential Information) prompt written notice of such request or requirement and reasonably consult with Buyer or Seller, as applicable, regarding the timing and content of such disclosure, (y) use commercially reasonable efforts (at Buyer’s or Seller’s, as applicable, expense) to cooperate with Buyer’s or Seller’s, as applicable, reasonable efforts to obtain a protective order or other remedy and (z) with respect to any disclosure, use commercially reasonable efforts to obtain assurances that confidential treatment will be accorded to the information being disclosed. It is understood that the foregoing shall not restrict Seller or its Affiliates from making such disclosure (1) as Seller or its Affiliates deem appropriate in their reasonable judgment (x) in connection with any issuance, incurrence or refinancing of any Indebtedness (including in any relevant offering documents or information memoranda), (y) in connection with any repayment or repurchase offer to the holders of Indebtedness under the Credit Facilities or any other Indebtedness of Seller or its Affiliates pursuant to the terms thereof or (z) pursuant to its reporting obligations under the Credit Facilities or the terms of any other Indebtedness of Seller or its Affiliates or (2) to potential acquirers of all or a material part of, or investors in, Seller’s business (other than the Business), in each case, so long as the recipients of such information are bound by customary confidentiality obligations with respect to such information.

(d)Buyer acknowledges and agrees that Seller and its Affiliates (excluding the Company) shall have the right to retain copies of all books, data, files, information and records in any media of the Company or the Business relating to periods ending on or prior to the Closing Date (i) relating to information (including employment and medical records) regarding the Business Employees, (ii) as may be required by any Governmental Authority, including pursuant to any applicable Law or regulatory request, (iii) as may be necessary for Seller or its Affiliates to perform their respective obligations pursuant to this Agreement or any of the Ancillary Agreements or (iv) constituting an Excluded Asset, in each case subject to compliance with all applicable privacy Laws (such retained books, data, files, information and records, collectively, the “Retained Information”). After the Closing Date, Seller and its Affiliates shall, until the seventh (7th) anniversary of the Closing Date, (A) make the Retained Information (other than any such Retained Information constituting an Excluded Asset) available for inspection and copying by Buyer or its Affiliates (at Buyer’s expense) and (B) cause the employees, counsel and financial advisors of Seller and its Affiliates to reasonably cooperate with Buyer and its Affiliates in connection with their ongoing financial reporting, accounting or other

30

purpose related to Buyer’s ownership of the Business after the Closing (including the provision of relevant parts of the books and records of the Company), during normal business hours, upon reasonable request and upon reasonable notice; provided that Seller and its Affiliates may, prior to the seventh (7th) anniversary, elect to destroy any such Retained Information so long as Seller notifies Buyer prior to the destruction of any such material Retained Information and gives Buyer a reasonable opportunity (at Buyer’s expense) to obtain possession thereof.

(e)After the Closing Date, Buyer shall, and shall cause the Company to, until the seventh (7th) anniversary of the Closing Date, (i) retain all material books, records and other documents pertaining to the Business that are in existence on the Closing Date and make the same available for inspection and copying by Seller and its Affiliates (at Seller’s expense) and (ii) cause the employees, counsel and financial advisors of Buyer and its Affiliates to reasonably cooperate with Seller and its Affiliates in connection with their ongoing financial reporting, accounting or other purpose related to Seller and its Affiliates ownership of the Business prior to the Closing (including the provision of relevant parts of the books and records of the Company), during normal business hours, upon reasonable request and upon reasonable notice; provided that Buyer and the Company may, prior to the seventh (7th) anniversary, elect to destroy any such information so long as Buyer notifies Seller prior to the destruction of any such information and give Seller a reasonable opportunity to obtain possession thereof.

(f)Each of Buyer and Seller shall, upon advance written request the other party, shall cause it and its Affiliates to make available, at reasonable times, such books and records and such directors, employees, and agents for fact finding, consultation, and interviews and as witnesses to the extent that any such Person may reasonably be requested by such party in connection with any pending or threatened Litigation, claim or demand asserted by a third party against Buyer, Seller or their respective Affiliates relating to pre-Closing Matters of the Business (excluding any threatened Litigation, claim or demand asserted by Buyer, Seller or their respective Affiliates against another party hereto). The requesting party shall promptly reimburse the other party and/or its Affiliates for any and all reasonable out-of-pocket costs in complying with its obligations under this Section 4.2(f).

(g)Upon advance written request by Buyer, Seller shall, and shall cause its Affiliates to make available, at reasonable times, the Retained Information and such directors, employees, and agents of Seller or its Affiliates for fact finding, consultation, and interviews and as witnesses to the extent that any such Person may reasonably be requested by Buyer in connection with any pending or threatened Litigation, claim or demand asserted by a third party (excluding Seller or their Affiliates) against Buyer or its Affiliates relating to pre-Closing matters of the Business (other than any Retained Assets and Retained Liabilities). Buyer shall promptly reimburse Seller and/or its Affiliates for any and all reasonable out-of-pocket costs in complying with its obligations under this Section 4.2(g).

Section 4.3    Governmental Approvals.

31

(a)Subject to the terms and conditions herein provided, each of Buyer and Seller shall, and shall cause their respective Affiliates to, use reasonable best efforts to take, or cause to be taken, all action and to do, or cause to be done, all things reasonably necessary, proper or advisable to consummate and make effective as promptly as practicable, and not take any action that would reasonably be expected to prevent, materially delay, impair, or impede, the transactions contemplated by this Agreement (including the satisfaction, but not waiver, of the conditions precedent set forth in Article 6). Each of Buyer and Seller shall, and shall cause their respective Affiliates to, use reasonable best efforts to promptly obtain consents of all Governmental Authorities necessary, proper or advisable to consummate the transactions contemplated by this Agreement. Each party hereto shall ensure that filings pursuant to the HSR Act and all other filings required by applicable Competition Laws for the jurisdictions set forth on Section 4.3 of the Seller Disclosure Letter with respect to the transactions contemplated by this Agreement are submitted promptly (and in any event, within ten (10) Business Days) after the date of this Agreement and shall resubmit any such filings as soon as is practicable in the event such filings are rejected for any reason whatsoever by the relevant Governmental Authority. Each party shall supply as promptly as practicable to any Governmental Authority information and documentary material that may be requested by such Governmental Authority in connection with this Agreement or the consummation of the transactions contemplated hereby (including, pursuant to the HSR Act, other Competition Laws or other applicable Laws). Without limiting the foregoing, Buyer, Seller and their respective Affiliates shall not extend any waiting period or comparable period under the HSR Act, other Competition Laws or other applicable Laws or enter into any agreement with any Governmental Authority not to consummate the transactions contemplated hereby, except with the prior written consent of the other party hereto. Notwithstanding the foregoing, nothing in this Section 4.3 or otherwise in this Agreement shall require Buyer, Canada Buyer or any of their respective Affiliates to propose or agree to the sale, divestiture, license or other disposition of any assets or businesses of Buyer, Canada Buyer or any of their respective Affiliates (including the Business) or otherwise take any action that limits its ability to retain any of the businesses, product lines or assets of Buyer, Canada Buyer or any of their respective Affiliates (including the Business).

(b)Each of Buyer and Seller will promptly notify the other party hereto of any written communication made to or received by either Buyer or Seller or any of their respective Affiliates, as the case may be, from any Governmental Authority regarding any of the transactions contemplated hereby, and, subject to applicable Law permit the other party hereto to review in advance any proposed written communication to any such Governmental Authority and consider in good faith and incorporate the other party’s reasonable comments, not agree to participate in any substantive meeting or discussion with any such Governmental Authority in respect of any filing, investigation or inquiry concerning this Agreement or the transactions contemplated hereby unless it consults with the other party hereto in advance and, to the extent permitted by such Governmental Authority, gives the other party the opportunity to attend, and furnish the other party with copies of all correspondence, filings and written communications (and summaries of any oral communications which a Governmental Authority does not permit the other party to attend) between them and their Affiliates and their respective representatives on one hand

32

and any such Governmental Authority or its respective staff on the other hand, with respect to this Agreement and the transactions contemplated hereby. Buyer and Seller shall consult with each other prior to taking any material position in discussions with or filings to be submitted to any Governmental Authority in connection with this Agreement. Buyer shall consult with Seller regarding process and strategy but shall have final decision making authority, including as to process and strategy, with respect to obtaining the required consents of any Governmental Authority to the transactions contemplated hereby.

(c)In the event any claim, action, suit, investigation or other proceeding by any Governmental Authority or other Person is commenced which questions the validity or legality of the transactions contemplated hereby or seeks damages in connection therewith, the parties hereto agree to cooperate and use reasonable best efforts to defend against such claim, action, suit, investigation or other proceeding and, if an injunction or other order is issued in any such action, suit or other proceeding, to use reasonable best efforts to have such injunction or other order lifted, and to cooperate reasonably regarding any other impediment to the consummation of the transactions contemplated hereby, in each case, in order to permit the consummation of the transactions contemplated hereby to occur as promptly as practicable. Buyer shall consult with Seller regarding any Litigation in connection with this Section 4.3 involving any Governmental Authority, but shall have final decision making authority regarding whether or not the parties will litigate to oppose any claim, action, suit, investigation or other proceeding or remove any court or regulatory orders impeding the ability to consummate the transactions contemplated by this Agreement (any such matter, an “Antitrust Proceeding”). In the event that Buyer determines not to defend or oppose any such Antitrust Proceeding, Buyer shall promptly give written notice of its decision to Seller (an “Antitrust Notice”).

Section 4.4    Employees and Employee Benefits

(a)Prior to the Closing Date, the employment of any Business Employee (other than the Canadian Business Employees) who is not employed by the Company as of the date of this Agreement shall (unless such Person has ceased to be employed by Seller and its Subsidiaries prior thereto) be transferred to, and each such employee shall become an employee of, the Company, without any interruption or cessation of employment, terms and conditions of employment or break in service. Each Business Employee employed by Seller or its Affiliates (including the Company) as of the Closing Date shall be referred to herein as a “Transferred Business Employee”. As of the Closing Date, Seller shall cause Transferred Business Employees to cease accruing any benefits under any Benefit Plan or Seller Plan with respect to services rendered or compensation paid on or after the Closing Date.

(i)At least ten (10) days prior to the Closing Date, Buyer shall, or shall cause one of its Affiliates to, offer employment in writing to each Canadian Business Employee conditional and effective on the Closing. Offers pursuant to this Section 4.4(a)(i) shall be for employment on substantially the same terms (including the same work location and comparable hours) as applicable to such

33

Canadian Business Employee immediately prior to the Closing, and shall otherwise comply with applicable Law with respect to such offers and this Section 4.4. Each Canadian Business Employee who accepts such offer of employment from Buyer or its Affiliate shall, upon the Closing Date, become a Transferred Business Employee for all purposes of this Agreement. A Canadian Business Employee shall be deemed to have accepted such offer of employment from Buyer or its Affiliate if such Canadian Business Employee presents himself or herself as available for work on the first Business Day for which such Canadian Business Employee is scheduled to work following the Closing. Notwithstanding the foregoing, Buyer may make an offer of employment pursuant to this Section 4.4(a)(i) to any Canadian Business Employee who is absent from work on the Closing Date due to approved leave (an “Inactive Business Employee”) that is conditional and effective on the date that such Inactive Business Employee returns to active employment (with or without accommodation required by applicable Law), and the Inactive Business Employee shall be deemed to be a “Transferred Business Employee” on the date such Inactive Business Employee returns to active employment.

(ii)In the event that either (a) a Canadian Business Employee does not, for any reason, become a Transferred Business Employee or (b) the consummation of the transactions contemplated by this Agreement, any action taken in order to effectuate such transactions, or Buyer’s or its Affiliates’ failure to provide to any Transferred Business Employee the terms and conditions of employment required under applicable Law, and in any such case such failure results in any obligation, contingent or otherwise, of Seller or its Affiliates to pay any termination pay, severance pay, pay in lieu of notice or other compensation or benefits to any Business Employee, or any additional Liability is incurred by Seller or its Affiliates in connection therewith, Buyer shall, and shall cause its Affiliates to, reimburse and otherwise hold harmless Seller and its Affiliates for all such compensation benefits and additional Liabilities (each, a “Business Employee Liability”).

(iii)Seller and its Affiliates shall use commercially reasonable efforts to assist the transition of the Canadian Business Employee to Buyer or one of its Affiliates, and shall instruct its officers not to attempt in any way to discourage any Canadian Business Employee from accepting the offer of employment made by Buyer or one of its Affiliates, provided, that nothing herein shall be construed as a representation or guarantee by Seller and its Subsidiaries that any particular Canadian Business Employee will accept such offer of employment.

(iv)Buyer shall not assume any of the Canada Benefit Plans. The Canadian Business Employees shall, as of the Closing Date, cease to accrue further benefits under the Canada Benefit Plans (or the date such Inactive Business Employee becomes a Transferred Business Employee). Buyer agrees that it shall permit the Canadian Business Employees who become Transferred Business Employees to participate in benefit plans sponsored by Buyer (such plans to be called the “Canada Replacement Plans”).

34

(b)During the period beginning on the Closing Date and ending on the first (1st) anniversary of the Closing Date (the “Continuation Period”), Buyer shall provide each Transferred Business Employee with (i) at least the same wage rate or base salary, level in effect for such Transferred Business Employee immediately prior to the Closing, and (ii) qualified retirement plan and welfare plan employee benefits (within the meaning of Section 3(1) of ERISA) that are no less favorable in the aggregate than those provided to such Transferred Business Employee immediately prior to the Closing. Through the conclusion of the 2021 calendar year, Buyer shall provide Transferred Benefit Employees, who were eligible under each applicable Seller Plan, with cash incentive compensation opportunities comparable to those provided to such Transferred Business Employees immediately prior to the Closing under the following Seller Plans: (i) annual Short-Term Incentive Plan; (ii) manufacturing gain share plan; and (iii) sales commission program (the “Continuing Incentive Opportunities”). For the duration of the Continuation Period following the end of the 2021 calendar year, each Transferred Business Employee shall be provided with cash incentive (including commission) opportunities comparable to those provided to Buyer’s (or its Affiliate’s) similarly situated employees. Except with respect to payments forfeited in connection with a termination of employment, the aggregate amount actually paid to the Transferred Business Employees for 2021 under the Continuing Incentive Opportunities shall be no less than the aggregate accrued amount of cash incentive compensation included in the Closing Date Working Capital, as governed by plans, programs or arrangements of Buyer and its Affiliates (including the Company) in Buyer’s discretion. Notwithstanding the foregoing, Buyer shall (x) not be prohibited by this Section 4.4(b) from terminating the employment of any Transferred Business Employee following the Closing Date and (y) in addition to meeting the applicable requirements of this Section 4.4, comply with any additional obligations arising under applicable Laws governing the terms and conditions or termination of employment of the Transferred Business Employees.

(c)As of and after the Closing, Buyer shall, or shall cause the Company to, give each Transferred Business Employee full credit for all purposes under (i) each employee benefit plan, policy or arrangement, and (ii) any paid time off policy, in each case maintained or made available for the benefit of Transferred Business Employees as of and after the Closing by Buyer or any of its Affiliates, for such Transferred Business Employee’s service prior to the Closing with Seller and its applicable Affiliates (including the Company) and their respective predecessors, to the same extent such service is recognized by Seller and its applicable Affiliates (including the Company) for analogous Seller Plans immediately prior to the Closing; provided that such credit shall not be given for purposes of benefit accrual under any defined benefit pension plan or to the extent that it would result in a duplication of benefits for the same period of service. With respect to US based Transferred Business Employees and in accordance the applicable plan terms, Buyer shall use commercially reasonable efforts to waive pre-existing condition exclusions, eligibility and waiting periods and evidence of insurability requirements under Buyer’s employee benefit plans in which Transferred Business Employees will participate following the Closing, as well as to provide credit for deductibles, coinsurance and other out-of-pocket costs incurred prior to the Closing Date for the year of Closing under such benefit plans.

35

(d)Buyer will recognize and assume all Liabilities with respect to accrued but unused vacation time for all Transferred Business Employees (including, without limitation, any Liabilities to Transferred Business Employees for payments in respect of earned but unused vacation time that arise as a result of the transfer of employment contemplated by this Section 4.4), to the extent such Liabilities are accrued and accounted for in the calculation of the Closing Date Net Working Capital (the “Transferred Business Employees Paid Time Off Liability”). Buyer shall allow Transferred Business Employees to use the vacation, sick leave and personal time recognized or established in accordance with the first sentence of this Section 4.4(d) in accordance with the terms of the paid time off programs of applicable to such Transferred Business Employees immediately prior to the Closing Date.

(e)Buyer and its Affiliates shall not at any time prior to ninety (90) days after the Closing Date effectuate a “plant closing” or “mass layoff” as such terms are defined in the Worker Adjustment and Retraining Notification Act of 1988 (“WARN”) or effectuate any similar triggering event under any other applicable Law, affecting in whole or in part any site of employment, facility, operating unit or Transferred Business Employee. Buyer agrees to provide any required notice under WARN and any other applicable Law and to otherwise comply with any such statute with respect to any “plant closing” or “mass layoff” (as defined in WARN) or any similar triggering event under any other applicable Law occurring on or after the Closing or arising as a result of the transactions contemplated hereby.

(f)Buyer and Seller acknowledge and agree that, with effect from the Closing Date, the Transferred Business Employees shall cease to be eligible to contribute to Seller’s and its Affiliates’ defined contribution savings plan(s) that are qualified under Section 401(a) of the Code (the “Seller’s Savings Plans”). With effect from the Closing Date, Buyer shall establish or otherwise maintain, or shall cause one or more of its Affiliates to establish or otherwise maintain, one or more defined contribution savings plans that are qualified under Section 401(a) of the Code (the “Buyer’s Savings Plan”) that shall permit immediate participation as of the Closing Date for the Transferred Business Employees who remain employed by a U.S. employer, credit all service that was credited under Seller’s Savings Plans for purposes of the eligibility, vesting and match eligibility requirements of Buyer’s Savings Plan, provide for tax-deferred contributions pursuant to Section 401(k) of the Code and accept elective direct rollovers of Transferred Business Employees’ accounts (including any loans) under Seller’s Savings Plans.

(g)With respect to the Transferred Business Employees who participate in the Seller Long-Term Incentive Plan prior to the Closing Date (as identified in the document described in Section 4.4(g) of the Seller Disclosure Letter, the “LTIP Summary”), Buyer shall compensate each such participant for any unvested equity-based awards under the Seller Long-Term Incentive Plan, as described in the LTIP Summary, that remain outstanding immediately prior to the Closing, pursuant to a cash-based bonus opportunity that will become payable on the terms described below (the “LTIP Replacement Bonus”). The portion of the LTIP Replacement Bonus available to be received by any holder of restricted stock units (“RSUs”) with respect to each award allocation, as described in the

36

LTIP Summary, shall equal the value of one (1) share of Seller’s common stock determined by using the average per share closing price reported on the New York Stock Exchange for each trading day over the preceding thirty (30) day look back period prior to the Closing Date (the “Per Share Value”) multiplied by the number of RSUs held on the Closing Date (the “Cash RSU Value”). Unless the value of such an award has otherwise been fixed prior to the Closing Date, the portion of the LTIP Replacement Bonus available to be received by any holder of performance restricted stock units (“PSUs”), as described in the LTIP Summary, shall be calculated with respect to the target number of such PSUs multiplied by the Per Share Value (the “Cash PSU Value”). The portion of the LTIP Replacement Bonus available to be received by any holder of options, as described in the LTIP Summary, shall equal, in the aggregate, the product of (x) the difference between the Per Share Value minus the applicable exercise price, multiplied by (y) the Per Share Value (such aggregate value, the “Cash Option Value”). For the avoidance of doubt, the total value of the LTIP Replacement Bonus that each individual described in the LTIP Summary shall be eligible to receive shall equal, to the extent applicable for each such individual, the sum of the Cash RSU Value (if any), the Cash PSU Value (if any) and the Cash Option Value (if any). Any amounts in respect of an LTIP Replacement Bonus potentially payable pursuant to this Section 4.4(g) shall be paid in accordance with the applicable vesting schedule for the RSUs, PSUs and options on which the value of such LTIP Replacement Bonus is based, in each case as identified in the LTIP Summary. Notwithstanding the foregoing, all compensation potential payable pursuant to the LTIP Replacement Bonuses described in this Section 4.4(g) shall be subject to the applicable participant’s remaining actively employed through the payment date consistent with the terms of the Seller Long-Term Incentive Plan. From the date hereof through the Closing, neither Seller nor any of its Affiliates shall grant any award pursuant to the Seller Long-Term Incentive Plan.

(h)From and after the Closing, Buyer shall honor (and assume as necessary), or shall cause the Company to honor (and assume as necessary), the Transferred Plans set forth on Section4.4(h) of the Seller Disclosure Letter as in effect immediately prior to the Closing.Nothing contained in this Agreement is intended to prevent Buyer, the Company or any of their Affiliates from amending or terminating any Transferred Plan in accordance with its terms after the Closing.

(i)Buyer and Seller hereby agree to follow the alternate procedure for United States employment tax withholding as provided in Section 5 of Rev. Proc. 2004-53, 2004-34 I.R.B. 320. Accordingly, Seller shall have no United States employment tax reporting responsibilities, and Buyer or its Affiliate, as the successor employer to Seller, shall have full United States employment tax reporting responsibilities, for Transferred Business Employees subject to United States employment taxes following the close of business on the Closing Date. In addition, Buyer and Seller hereby agree to adopt the “alternative procedure” of Revenue Procedure 2004-53 for purposes of filing IRS Forms W-4 (Employee’s Withholding Allowance Certificate) and W-5 (Earned Income Credit Advance Payment Certificate).

(j)Without limiting the provisions of Exhibit B or this Agreement, Buyer and Seller hereby agree that with respect to all Pre-Closing Employment Liabilities provided

37

for in subsection (c) of the definition thereof (costs for timely submitted outstanding and unpaid health claims arising prior to the Closing Date for Business Employees and their dependents and beneficiaries under any self-insured Seller Plan providing for group health benefits), Seller shall or shall through the applicable Seller Plan pay or satisfy all valid claims incurred prior to the Closing in full in a timely manner in accordance with the terms of the applicable Seller Plan and shall provide Buyer with a written request for reimbursement for such payments (after applying any applicable stop loss coverage reimbursement), which shall contain evidence, which shall not include “Protected Health Information” (within the meaning of the Health Insurance Portability and Protection Act of 1996), of such payment accompanying any requests for reimbursement. Buyer shall reimburse Seller for the amount of such payments subject to the reimbursement request within thirty (30) days of the receipt of the applicable request for reimbursement; provided, however, that Buyer shall have no obligation to reimburse Seller with respect to any claim submitted to Seller or the applicable Seller Plan following the (6) month anniversary of the Closing Date that was not paid by Seller with ninety (90) days of the receipt of claim. In the event of a dispute regarding whether a payment is validly subject to reimbursement under this provision, including the determination of whether such claim is covered by the reimbursement mechanism contained herein, Buyer and Seller agree to take commercially reasonable steps to resolve such dispute in a timely manner.

(k)Seller acknowledges and agrees that from and after the Closing Date Seller shall have no right to enforce any non-competition covenant contained in any Retention Letter identified on Schedule 2.16(a)(i) in respect of the services performed from and after the Closing Date by any Retention Letter holder on behalf of the Company, any Affiliate or Buyer.

(l)Nothing contained in this Section 4.4, expressed or implied, is intended to confer upon any Person any benefits under any benefit plans, programs, policies or other arrangements, including severance benefits or right to employment or continued employment with Buyer for any period. In addition, the provisions of this Agreement, in particular this Section 4.4, are solely for the benefit of the parties to this Agreement and no current or former employee shall be regarded for any purpose as a third-party beneficiary of this Agreement or otherwise entitled to enforce the provisions of this Section 4.4.

Section 4.5    Public Announcements. Neither Buyer nor Seller shall make, or permit any of their respective Affiliates or representatives to make, any public announcement in respect of this Agreement, the Ancillary Agreements or the transactions contemplated hereby or thereby without the prior written consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), except as may be required (a) to obtain consents and approvals, and to provide such notices and make such filings, necessary, proper or reasonably advisable to consummate the transactions contemplated by this Agreement, (b) by Law, rule or regulation applicable to Buyer or Seller or any of their respective Affiliates, including reporting required of Buyer or Seller under the Exchange Act (and only to the extent so required) or (c) in the case of Buyer or Seller, pursuant to internal announcements to employees; provided, that the announcing party shall inform the other party prior to any such announcement and consider in good faith any comments from such other party prior to making any such announcement, and any

38

such disclosure is generally consistent with the parties’ prior public disclosures regarding the transactions contemplated hereby. It is understood that the foregoing shall not restrict Seller and its Affiliates from making disclosure (i) as Seller or its Affiliates deem appropriate in its reasonable judgment (A) in connection with any issuance, incurrence or refinancing of any Indebtedness (including in any relevant offering documents or information memoranda), (B) in connection with any repayment or repurchase offer to the holders of indebtedness for borrowed money under the Credit Facilities or any other indebtedness for borrowed money of Seller or its Affiliates pursuant to the terms thereof or (C) pursuant to its reporting obligations under the Credit Facilities or the terms of any other Indebtedness of Seller or its Affiliates or (ii) to potential acquirers of all or a material part of, or investors in, Seller’s business (other than the Business), in each case, so long as the recipients of such information are bound by customary confidentiality obligations with respect to such information.

Section 4.6    D&O Indemnification.

(a)From and after the Closing Date until six (6) years from the Closing Date, Buyer shall or shall cause the Company to indemnify, defend, hold harmless, and advance expenses to (to the extent consistent with the Company’s Organizational Documents as of the Closing Date), the individuals who on or prior to the Closing Date were directors or officers of the Company with respect to all acts or omissions by them in their capacities as such or taken at the request of the Company at any time on or prior to the Closing Date.

(b)Except as required by applicable Law, the certificates of incorporation, by-laws and all other organization documents of the Company shall not be amended, repealed or otherwise modified for a period of three (3) years from the Closing Date in any manner that would adversely affect the rights thereunder of individuals who at or at any time prior to the Closing Date were directors, officers, agents or employees of the Company or otherwise entitled to indemnification pursuant to the Company’s certificate of incorporation, by-laws or other Organizational Documents.

(c)Buyer shall cause the Company to obtain with effect from the Closing Date and shall cause the Company to maintain in effect for six (6) years after the Closing Date a “run-off” or “tail” directors’ and officers’ liability insurance policy to the current policy for the Company with respect to matters occurring prior to the Closing and having coverage limits in at least the same aggregate amount as provided in the current policy for such six (6)-year period and terms and conditions otherwise no less advantageous to the indemnitees than the terms and conditions of the current policy for the Company. The provisions of this Section 4.6 are intended to be for the benefit of, and shall be enforceable by, each officer and director entitled to indemnification under this Section 4.6, his or her heirs and his or her representatives and are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by contract or otherwise. From and after the Closing Date, Buyer hereby agrees that the Company is the indemnitor of first resort (i.e., their obligations to such officers and directors are primary and any obligation of any secondary indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by any such officer or director are secondary).

39

Section 4.7    R&W Insurance. At its election, on or prior to the Closing, Buyer may procure a buyer-side representation and warranty insurance policy (the “R&W Insurance Policy”) the cost of the premium of which will be borne fifty percent (50%) by Buyer and fifty percent (50%) by Seller. Seller’s portion of the cost of such premium shall be treated as a Transaction Expense. Any such R&W Insurance Policy shall include a provision whereby the insurer under the R&W Insurance Policy expressly waives, and agrees not to pursue, directly or indirectly, any subrogation rights against Seller or its Affiliates or any former or current equityholder(s), managers, members, directors, officers, employees, agents or representatives of Seller or its Affiliates in connection with this Agreement and the transactions contemplated hereby with respect to any claim made by an insured thereunder, except in the case of Fraud by any such Person in connection with this Agreement. Buyer shall not waive, amend or modify such subrogation provision, or allow such subrogation provision to be waived, amended or modified, without the prior written consent of Seller.

Section 4.8    Resignations. On the Closing Date, Seller shall cause to be delivered to Buyer duly signed resignations, effective immediately after the Closing, of all of the directors of the Company and the officers thereof, and shall take such other action as is necessary to cause such persons to no longer be directors or officers of the Company, as the case may be, immediately after the Closing.

Section 4.9    Affiliate Agreements; Intercompany Balances. Prior to the Closing Date, Seller shall cause all Affiliate Contracts to be settled or terminated prior to the Closing without any Liability on the part of the Company (following Closing), Buyer or any of its Affiliates (including Liability arising from such termination), except for this Agreement, the Ancillary Agreements, as contemplated by Section 4.10, those contracts or other transactions set forth on Section 4.9 of the Seller Disclosure Letter. For the avoidance of doubt, such settlement shall, to the extent applicable, include Seller causing to be paid or discharged any intercompany Indebtedness owed by or to the Company.

Section 4.10    Pre-Closing Steps; Third-Party Consents.

(a)Prior to the Closing, Seller shall, and shall cause its applicable Affiliates to, take all actions necessary to effect and carry out the steps set forth in Exhibit B (such steps set forth in Exhibit B, the “Pre-Closing Steps”) as the same may be amended by mutual written agreement between Seller and Buyer, including making timely requests for any required third party consents or approvals to transfer any Material Contracts; provided that, and subject to the proviso at the end of this clause (a), in the event the Pre-Closing Steps (other than Clause 2 thereof) have not been completed as of Closing notwithstanding the reasonable best efforts of Seller, due solely to the failure to obtain one or more third party consents or approvals or other action of a Governmental Authority or other third party, in each case, that is legally necessary for a Transferred Business Contract to be transferred or an Assumed Liability relating thereto to be assumed, in each case, as contemplated hereby, or because such transfer or assumption would violate any applicable Law, Seller shall be deemed to have complied with this clause (a) for purposes of satisfying the condition to Closing; provided, however, (i) the foregoing shall not be deemed to include the failure by Seller to (A) obtain the Required Consents, (B) complete the amalgamation of Robertson Building Systems, Limited and

40

Gienow Canada Inc.

(b)Upon receipt of notice of a claim for indemnity from an Indemnified Party pursuant to this Section 8.5 in respect of a pending or threatened claim or demand by a third party that the Indemnified Party has determined has given or could reasonably give rise to a right of indemnification under this Agreement (such claim or demand being a “Third-Party Claim” and including a pending or threatened claim or demand asserted by a third party against the Indemnified Party), the Indemnifying Party may, by notice to the Indemnified Party delivered within twenty (20) Business Days of the receipt of notice of such Third-Party Claim, assume the defense and control of such Third-Party Claim, with its own counsel and at its own expense and the Indemnified Party shall, at its sole cost and expense, cooperate with the Indemnifying Party in connection therewith; provided that the Indemnifying Party shall allow the Indemnified Party a reasonable opportunity to participate in the defense of such Third-Party Claim with its own counsel and at its own expense. So long as the Indemnifying Party is reasonably contesting any such Third-Party Claim in good faith, the Indemnified Party shall not pay or settle any such Third-Party Claim. If the Indemnifying Party elects to conduct the defense and settlement of a Third-Party Claim, then the Indemnified Party shall have the right to pay or settle such Third-Party Claim; provided that in such event it shall waive any right to indemnity by the Indemnifying Party for all Losses related to such Third-Party Claim unless the Indemnifying Party shall have consented to such payment or settlement. If the Indemnifying Party does not notify the Indemnified Party within twenty (20) Business Days after the receipt of the Indemnified Party’s notice of a claim hereunder that it elects to undertake the defense thereof, the Indemnified Party shall have the right to contest, settle or compromise the claim but shall not thereby waive any right to indemnity therefor pursuant to this Agreement. The Indemnifying Party shall not, except with the consent of the Indemnified Party (which shall not be unreasonably withheld, conditioned or delayed), enter into any settlement that does not include as a term thereof the giving by the Person(s) asserting such claim to all Indemnified Parties of a release from all Liability with respect to such claim or consent to entry of any judgment.

(a)This Agreement shall be governed in all respects, including as to validity, interpretation and effect, by the Laws of the State of Delaware, without giving effect to its principles or rules of conflict of laws, to the extent such principles or rules are not mandatorily applicable by statute and would permit or require the application of the Laws of another jurisdiction. Each of the parties hereto (i) submits to the jurisdiction of the federal and state courts sitting in the State of Delaware, in any action or proceeding arising out of or relating to this Agreement, and (ii) other than pursuant to Section 1.2(c)(iii) above, (A) agrees to bring all claims under any theory of liability in respect of such action or proceeding exclusively in any such court and (B) agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court. Each of the parties hereto waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto. Each party hereto agrees that service of summons and complaint or any other process that might be served in any action or proceeding may be made on such party by sending or delivering a copy of the process to the party to be served at the address of the party and in the manner provided for the giving of notices in Section 10.1. Nothing in this Section 10.4, however, shall affect the right of any party to serve legal process in any other manner permitted by Law. Each party hereto agrees that a final, non-appealable judgment in any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by Law.

(b)Each party to this Agreement hereby waives, to the fullest extent permitted by Law, any right to trial by jury of any claim, demand, action, or cause of action (i) arising under this Agreement or (ii) in any way connected with or related or incidental to the dealings of the parties hereto in respect of this Agreement or any of the transactions related hereto, in each case whether now existing or hereafter arising, and whether in contract, tort, equity or otherwise. Each party to this Agreement hereby agrees and consents that, other than pursuant to Section 1.2(c)(iii) above, any such claim, demand, action, or cause of action shall be decided by court trial without a jury and that the parties to this Agreement may file an original counterpart of a copy of this Agreement with any court as written evidence of the consent of the parties hereto to the waiver of their right to trial by jury.

Section 10.5    Successors and Assigns. This Agreement and the Ancillary Agreements shall be binding upon and inure to the benefit of the parties and their respective heirs, successors and permitted assigns; provided that this Agreement shall not be assigned by any party hereto (whether by operation of Law or otherwise), without the prior written consent of the other party.

72

Any attempted assignment of this Agreement not in accordance with the terms of this Section 10.5 shall be void.

Section 10.7    Severability. If any term or other provision of this Agreement is determined by a court of competent jurisdiction to be invalid, illegal or unenforceable, all other provisions of this Agreement shall remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon any such determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 10.8    Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall together constitute one and the same instrument.

Section 10.9    Specific Performance. Each party acknowledges and agrees that the other party would be damaged irreparably in the event that any provision of this Agreement is not performed in accordance with its specific terms or otherwise breached, so that, in addition to any other remedy that a party may have under law or equity, a party shall be entitled to injunctive relief to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof. Each party acknowledges and agrees that monetary damages would be inadequate in the event of any such failure to perform or breach, and waives any equitable defense to the granting of specific performance or other injunctive relief available to such party. Any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction. In the event that a court of competent jurisdiction fails to grant specific performance or other injunctive relief to a party as a remedy for such failure to perform or breach, the parties hereby acknowledge and agree that such party shall be entitled to receive benefit of the bargain and lost profits damages as redress for such failure to perform or breach. Notwithstanding anything to the contrary in this Agreement, the parties hereby irrevocably waive any right of rescission they may otherwise have or to which they may become entitled.

or shall confer upon any other Person any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement.

The Seller Disclosure Letter and the information and statements contained therein are not intended to constitute, and shall not be construed as constituting, representations or warranties of Seller or its Affiliates except as and to the extent expressly provided in this Agreement.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited consolidated financial statements for Cornerstone Building Brands, Inc. (together with its subsidiaries, unless otherwise indicated, the “Company,” “Cornerstone,” “we,” “us” or “our”) have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles (“GAAP”) for complete financial statements. In the opinion of management, the unaudited consolidated financial statements included herein contain all adjustments, which consist of normal recurring adjustments, necessary to fairly present the Company’s financial position, results of operations and cash flows for the periods indicated. Operating results for the period from January 1, 2021 through July 3, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2021.

 Certain reclassifications have been made to the prior period amounts in the consolidated financial statements to conform to the current presentation.

For additional information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the Securities and Exchange Commission (the “SEC”) on March 4, 2021.

Reporting Periods

The Company’s fiscal quarters are based on a four-four-five week calendar with periods ending on the Saturday of the last week in the quarter except that December 31st will always be the year-end date. Therefore, the financial results of certain fiscal quarters may not be comparable to prior fiscal quarters.

Restricted Cash

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheets that total the amounts shown in the consolidated statements of cash flows (in thousands):

	July 3, 2021		December 31, 2020
Cash and cash equivalents	$	88,978	$	674,255
Restricted cash(1)	6,224		6,223
Total cash, cash equivalents and restricted cash shown in the consolidated statements of cash flows	$	95,202	$	680,478

(1)Restricted cash primarily relates to escrow balances held for an outstanding earn-out agreement and other indemnification agreements.

Accounts Receivables and Related Allowance

The Company reports accounts receivable net of the allowance for expected credit losses. Trade accounts receivable are the result of sales of vinyl windows, aluminum windows, vinyl siding, metal siding, injection molded products, metal building products, insulated metal panels, metal coating, and other products and services to customers throughout the United States and Canada and affiliated territories, including international builders who resell to end users. Sales are primarily denominated in U.S. dollars. Credit sales do not normally require a pledge of collateral; however, various types of liens may be filed to enhance the collection process and we require payment prior to shipment for certain international shipments.

The Company establishes provisions for expected credit losses based on the Company’s assessment of the collectability of amounts owed to us by our customers. Such provisions are included in selling, general and administrative expenses. In establishing these reserves, the Company considers changes in the financial position of a customer, age of the accounts receivable balances, availability of security, unusual macroeconomic conditions, lien rights and bond rights as well as disputes, if any, with our customers. Our allowance for credit losses reflects reserves for customer receivables to reduce receivables to amounts expected to be collected. Interest on delinquent accounts receivable is included in the trade accounts receivable balance and recognized as interest income when earned and collectability is reasonably assured. Uncollectible accounts are written off when a settlement is reached for an amount that is less than the outstanding historical balance, all collection efforts have been exhausted, and/or any legal action taken by the Company has concluded.

The following table represents the rollforward of the allowance for credit losses for the periods indicated (in thousands):

	Six Months Ended
	July 3, 2021		July 4, 2020
Ending balance, prior period	$	13,313	$	9,962
Cumulative effect of accounting change(1)	—		678
Provision for expected credit losses	1,428		252
Amounts charged against allowance for credit losses, net of recoveries	(750)		(2,076)
Held for sale adjustment	(3,651)		—
Allowance for credit losses of acquired company at date of acquisition	—		810
Ending balance	$	10,340	$	9,626

(1)Cumulative effect of accounting change reflects the modified retrospective effect of adopting ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.

Net Sales

The Company enters into contracts that pertain to products, which are accounted for as separate performance obligations and are typically one year or less in duration. Given the nature of the Company's sales arrangements, we are not required to exercise significant judgment in determining the timing for the satisfaction of performance obligations or the transaction price. Revenue is measured as the amount of consideration expected to be received in exchange for our products. Revenue is generally recognized when the product has shipped from our facility and control has transferred to the customer. For a portion of our business, when we process customer owned material, control is deemed to transfer to the customer as the processing is being completed.

The Company’s revenues are adjusted for variable consideration, which includes customer volume rebates and prompt payment discounts. The Company measures variable consideration by estimating expected outcomes using analysis and inputs based upon anticipated performance, historical data, and current and forecasted information. Customer returns are recorded as a reduction to sales on an actual basis throughout the year and also include an estimate at the end of each reporting period for future customer returns related to sales recorded prior to the end of the period. The Company generally estimates customer returns based upon the time lag that historically occurs between the sale date and the return date while also factoring in any new business conditions that might impact the historical analysis such as new product introduction. Measurement of variable consideration is reviewed by management periodically and revenue is adjusted accordingly. We do not have significant financing components. The Company recognizes installation revenue, primarily within the stone veneer business, over the period for which the stone is installed, which is typically a very short duration.

Shipping and handling activities performed by us are considered activities to fulfill the sales of our products. Amounts billed for shipping and handling are included in net sales, while costs incurred for shipping and handling are included in cost of sales.

In accordance with certain contractual arrangements, we receive payment from our customers in advance related to performance obligations that are to be satisfied in the future and recognize such payments as deferred revenue, primarily related to the Company’s weathertightness warranties (see Note 12 — Warranty).

A portion of the Company’s revenue, exclusively within the Commercial segment, includes multiple-element revenue arrangements due to multiple deliverables. Each deliverable is generally determined based on customer-specific manufacturing and delivery requirements. Because the separate deliverables have value to the customer on a stand-alone basis, they are typically considered separate units of accounting. A portion of the entire job order value is allocated to each unit of accounting. Revenue allocated to each deliverable is recognized upon shipment. The Company uses estimated selling price (“ESP”) based on underlying cost plus a reasonable margin to determine how to separate multiple-element revenue arrangements into separate units of accounting, and how to allocate the arrangement consideration among those separate units of accounting. The Company determines ESP based on normal pricing and discounting practices.

The following table presents disaggregated revenue disclosure details of net sales by segment (in thousands):

Accounting Standards Update and Change in Accounting Principle [Abstract]

ACCOUNTING PRONOUNCMENTS

ACCOUNTING PRONOUNCEMENTS

Adopted Accounting Pronouncements

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and also improves consistent application of and simplifies U.S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. Effective January 1, 2021, the Company adopted this guidance. The application of ASU 2019-12 did not have a material effect on the consolidated financial statements.

Recent Accounting Pronouncements

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, which provides optional guidance to ease the potential burden in accounting for reference rate reform on financial reporting. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope, which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the reference rate transition. The amendments in these ASUs are elective, apply to all entities that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of rate reform, and may be adopted as of March 12, 2020 through December 31, 2022. The Company is evaluating the impact of electing to apply the amendments.

Business Combination and Asset Acquisition [Abstract]

ACQUISITIONS

ACQUISITIONS

2021 Acquisition

On April 30, 2021, the Company acquired Prime Windows LLC (“Prime Windows”) for total consideration of $93.0 million, exclusive of a $2.0 million working capital adjustment which has not been finalized as of July 3, 2021. Prime Windows serves residential new construction and repair and remodel markets with energy efficient vinyl window and door products from two manufacturing facilities in the United States, expanding our manufacturing capabilities and creating new opportunities for us in the Western United States. This acquisition was funded through borrowings under the Company’s existing credit facilities. Prime Windows’ results are reported within the Windows segment.

The Company preliminarily determined the fair value of the tangible and intangible assets and the liabilities acquired, and recorded goodwill based on the excess of the fair value of the acquisition consideration over such fair values, as follows (in thousands):

Assets acquired:
Cash	$	997
Accounts receivable	5,500
Inventories	4,295
Prepaid expenses and other current assets	823
Property, plant and equipment	2,000
Lease right of use assets	2,637
Intangible assets (trade names/customer relationships)	52,700
Goodwill	31,770
Other assets	50
Total assets acquired	100,772
Liabilities assumed:
Accounts payable	1,676
Other accrued expenses	1,429
Lease liabilities	2,637
Total liabilities assumed	5,742
Net assets acquired	$	95,030

The $31.8 million of goodwill was allocated to the Windows segment and is expected to be deductible for tax purposes. The goodwill is primarily attributable to the synergies expected to be realized.

During the three and six months ended July 3, 2021, the Company incurred $0.7 million of acquisition-related costs for Prime Windows, $0.3 million of which are recorded in strategic development and acquisition related costs in the Company’s consolidated statements of operations.

Due to the recent closing of the transaction, the purchase price allocation is preliminary and will be finalized when valuations are complete and final assessments of the fair value of acquired assets and assumed liabilities are completed. There can be no assurance that such finalization will not result in material changes from the preliminary purchase price allocations. The Company’s estimates and assumptions are subject to change during the measurement period (up to one year from the acquisition date), as the Company finalizes the valuations of accounts receivable, inventories, prepaid expenses, property, plant and equipment, lease right of use assets, goodwill, intangible assets, other assets, accounts payable, other accrued expenses, deferred income taxes and lease liabilities.

2020 Acquisition

On March 2, 2020, the Company acquired 100% of the issued and outstanding shares of the common stock of Kleary Masonry, Inc. (“Kleary”) for total consideration of $40.0 million, exclusive of the $2.0 million working capital adjustment that was finalized during the three months ended July 4, 2020. The transaction was financed with cash on hand and through borrowings under the Company’s asset-based revolving credit facility. Kleary’s results are reported within the Siding segment.

The Company determined the fair value of the tangible and intangible assets and the liabilities acquired, and recorded goodwill based on the excess of the fair value of the acquisition consideration over such fair values, as follows (in thousands):

Assets acquired:
Cash	$	143
Accounts receivable	7,135
Inventories	670
Prepaid expenses and other current assets	277
Property, plant and equipment	1,042
Lease right of use assets	445
Intangible assets (trade names/customer relationships)	22,350
Goodwill	12,539
Total assets acquired	44,601
Liabilities assumed:
Accounts payable	1,149
Other accrued expenses	1,020
Lease liabilities	339
Other long-term liabilities	109
Total liabilities assumed	2,617
Net assets acquired	$	41,984

The $12.5 million of goodwill from the Kleary acquisition was allocated to the Siding segment and will be deductible for tax purposes. The goodwill is attributable to the workforce of the acquired business and the synergies expected to be realized. The fair value of all assets acquired and liabilities assumed was finalized during the first quarter of 2021.

Strategic development and acquisition related costs in the consolidated statements of operations for the three and six months ended July 3, 2021 included a reduction of $4.2 million to the previously estimated accrual to reflect the final contingent earnout for the Kleary acquisition at approximately $5.4 million.

Unaudited Pro Forma Financial Information

During the three and six months ended July 3, 2021, Prime Windows contributed net sales of $13.0 million and net income of $0.7 million which has been included within the Company’s consolidated statement of operations. The following table provides unaudited supplemental pro forma results for Cornerstone for the three and six months ended July 3, 2021 and July 4, 2020 as if the Prime Windows and Kleary acquisitions had occurred on January 1, 2020 (in thousands, except for per share data):

	Three Months Ended				Six Months Ended
	July 3, 2021		July 4, 2020		July 3, 2021		July 4, 2020
Net sales	$	1,406,296	$	1,098,542	$	2,691,089	$	2,234,251
Net income (loss) applicable to common shares	9,609		28,649		9,827		(510,707)
Net income (loss) per common share:

Diluted	$	0.08	$	0.23	$	0.08	$	(4.06)

The unaudited supplemental pro forma financial information was prepared based on the historical information of Cornerstone, Prime Windows and Kleary. The unaudited supplemental pro forma financial information does not give effect to the potential impact of current financial conditions, any anticipated synergies, operating efficiencies or cost savings that may result from the acquisitions or any integration costs. Unaudited pro forma balances are not necessarily indicative of operating results had the Prime Windows and Kleary acquisitions occurred on January 1, 2020 or of future results.

Restructuring and Related Activities [Abstract]

RESTRUCTURING

RESTRUCTURING

The Company has various initiatives and programs in place within its business units to reduce selling, general, and administrative expenses (“SG&A”), manufacturing costs and to optimize the Company’s combined manufacturing footprint.

For the three and six months ended July 3, 2021, total restructuring costs are recorded within restructuring and impairment costs in the consolidated statements of operations. The asset impairments of $4.0 million for the six months ended July 3, 2021 primarily included assets held for sale that were recorded at fair value less cost to sell, which was less than the assets’ carrying amount, and the write-off of previously capitalized software development costs.

The following table summarizes our severance liability, included within other accrued expenses on the consolidated balance sheets, and cash payments made pursuant to the restructuring plans from inception through July 3, 2021 (in thousands):

ASSETS AND LIABILITIES HELD FOR SALE

ASSETS AND LIABILITIES HELD FOR SALE

ASSETS AND LIABILITIES HELD FOR SALE

An asset or business is classified as held for sale when: (i) management has the authority and commits to a plan to sell the asset; (ii) the asset is available for immediate sale in its present condition; (iii) there is an active program to locate a buyer and the plan to sell has been initiated; (iv) the sale is probable within one year; (v) the asset is being actively marketed at a reasonable sale price relative to its current fair value; and (vi) it is unlikely that the plan to sell will be withdrawn or that significant changes to the plan will be made. Upon being classified as held for sale, the recoverability of the carrying value must be assessed. Evaluating the recoverability of the assets of a business classified as held for sale follows a defined order in which property and intangible assets subject to amortization are considered only after the recoverability of goodwill and other assets are assessed. In determining the fair value of the assets less cost to sell, we consider factors including current sales prices for comparable assets in the area, recent market analysis studies, appraisals and any recent legitimate offers. After the valuation process is completed, the assets held for sale are reported at the lower of the carrying value or fair value less cost to sell, and the assets are no longer depreciated or amortized. An impairment charge is recognized if the carrying value exceeds the fair value less cost to sell. The assets and related liabilities are aggregated and reported on separate lines of the balance sheet.

In June 2021, we entered into definitive agreements to sell our insulated metal panels (IMP) business for $1.0 billion in cash and roll-up sheet door (DBCI) business for $168 million in cash within the Commercial segment. The transactions are expected to close in the second half of 2021, subject to regulatory approval and other customary closing conditions. We determined that the assets and liabilities associated with each of these transactions met the held for sale criteria during the three months ended July 3, 2021. Accordingly, the respective assets and liabilities were classified in the consolidated balance sheet at July 3, 2021 as held for sale. Additionally, we ceased recording depreciation and amortization for the held for sale assets upon meeting the held for sale criteria. The transactions do not represent strategic shifts that will have a major effect on our operations and financial results, so they are not presented as discontinued operations. We determined the estimated fair value of these transactions based on the sales price defined by each respective definitive agreement. The estimated fair value less cost to sell exceeds the respective carrying amount for the IMP and DBCI businesses, therefore no impairment was recognized in the three months ended July 3, 2021.

The following table reconciles the carrying amounts of major classes of assets and liabilities that are classified as held for sale in the consolidated balance sheets (in thousands):

	July 3, 2021		December 31, 2020

There were no asset sales completed in the three months ended July 3, 2021. During the six months ended July 3, 2021, the Company completed the sale of certain real property assets resulting in approximately $0.7 million in net proceeds and an immaterial loss from the transaction.

Due to uncertainties in the estimation process, actual results could differ from the estimates used in our historical analysis. Our assumptions about property sales prices require significant judgment because the current market is highly sensitive to changes in economic conditions. We determined the estimated fair values of real property assets held for sale based on current market conditions and assumptions made by management, which may differ from actual results and may result in impairments if market conditions deteriorate.

LEASES

Leases [Abstract]

LEASES

LEASES

The Company leases certain manufacturing, warehouse and distribution locations, vehicles and equipment, including fleet vehicles. Many of these leases have options to terminate prior to or extend beyond the end of the term. The exercise of the majority of lease renewal options is at the Company’s sole discretion. Some lease agreements have variable payments, the majority of which are real estate agreements in which future increases in rent are based on an index. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company accounts for lease and non-lease components as a single lease component for all leases other than leases of durable tooling. The Company excludes leases with an initial term of 12 months or less from the consolidated balance sheets and recognizes related lease payments in the consolidated statements of operations on a straight-line basis over the lease term.

Operating lease liabilities are recognized based on the present value of the future minimum lease payments over the reasonably expected holding period at the commencement date of the leases. Few of the Company’s lease contracts provide a readily determinable implicit rate. For these contracts, an estimated incremental borrowing rate (“IBR”) is utilized, based on information available at the inception of the lease. The incremental borrowing rate represents an estimate of the interest rate we would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of the lease.

Accounting for leases may require judgment, including determining whether a contract contains a lease, the incremental borrowing rates to utilize for leases without a stated implicit rate, the reasonably certain holding period for a leased asset, and the allocation of consideration to lease and non-lease components. The allocation of the lease and non-lease components for leases of durable tooling is based on the Company’s best estimate of standalone price.

Weighted average information about the Company’s lease portfolio as of July 3, 2021 was as follows:

Weighted-average remaining lease term	6.0 years

SHARE-BASED COMPENSATION

Share-based Payment Arrangement [Abstract]

SHARE-BASED COMPENSATION

SHARE-BASED COMPENSATION

Our 2003 Long-Term Stock Incentive Plan, as amended (the “Incentive Plan”), is an equity-based compensation plan that allows us to grant a variety of types of awards, including stock options, restricted stock awards, stock appreciation rights, cash awards, phantom stock awards, restricted stock unit awards (“RSUs”) and long-term incentive awards with performance conditions (“performance share units” or “PSUs”). Awards are generally granted once per year, with the amounts and types of awards determined by the Compensation Committee of our Board of Directors (the “Committee”). In connection with the Merger (as defined herein) with Ply Gem Parent, LLC (“Ply Gem”), on November 16, 2018 awards were granted to certain senior executives and key employees (the “Founders Awards”), which included stock options, RSUs, and PSUs. A portion of the Founders Awards was not granted under the Incentive Plan but was instead granted pursuant to a separate equity-based compensation plan, the Long-Term Incentive Plan. These Founders Awards were subject award agreements with the same terms and provisions as awards of the same type granted under the Incentive Plan.

As of July 3, 2021, and for all periods presented, the Founders Awards and our share-based awards under the Incentive Plan have consisted of RSUs, PSUs and stock option grants, none of which can be settled through cash payments. Both our stock options and restricted stock awards are subject only to vesting requirements based on continued employment through the end of a specified time period and typically vest in annual increments over three to five years or earlier upon death, disability or a change in control. As a general rule, option awards expire on the earlier of (i) 10 years from the date of grant, (ii) 60 days after termination of employment or service for a reason other than death, disability or retirement, or (iii) 180 days after death, disability or retirement. Awards are non-transferable except by disposition on death or to certain family members, trusts and other family entities as the Committee may approve.

Our time-based restricted stock awards are typically subject to graded vesting over a service period, which is three to five years. Our performance-based and market-based restricted stock awards are typically subject to cliff vesting at the end of the service period, which is typically three years. Our share-based compensation arrangements are equity classified and we recognize compensation cost for these awards on a straight-line basis over the requisite service period for each award grant. In the case of performance-based awards, expense is recognized based upon management’s assessment of the probability that such performance conditions will be achieved. Certain of our awards provide for accelerated vesting upon a change of control or upon termination without cause or for good reason.

Vesting of the PSUs granted as part of the Founders Awards is contingent upon the achievement of synergies captured from the Merger and continued employment. Based on achieved synergies during the period comprising the two fiscal years ended December 31, 2020, the Founders Awards will vest at 200% of target amounts, subject to continuing employment through the requisite service period ending on November 16, 2021. Vesting of the PSUs granted under the Incentive Plan during the six months ended July 3, 2021 and July 4, 2020 are contingent upon achievement of a cumulative three-year EBITDA growth target with an additional modifier based on total shareholder return. The grant-date fair value of the PSUs granted during the six months ended July 3, 2021 and July 4, 2020 were determined by a Monte Carlo simulation.

Stock option awards

During the six months ended July 3, 2021 and July 4, 2020, we granted 0.6 million and 1.0 million stock options, respectively. The average grant date fair value of options granted during the six months ended July 3, 2021 and July 4, 2020 was $6.50 and $1.96 per share, respectively. There were 0.1 million options with an intrinsic value of $0.7 million exercised during the six months ended July 3, 2021 and cash received from the options exercised was $1.5 million. No options were exercised during the six months ended July 4, 2020.

Restricted stock units and performance share units

Annual awards to our key employees generally have a three-year performance period. The fair value of RSUs awarded is based on the Company’s stock price as of the date of grant. During the six months ended July 3, 2021, we granted RSUs to key employees with a fair value of $11.6 million representing approximately 0.8 million shares. During the six months ended July 4, 2020, we granted RSUs to key employees with a fair value of $6.1 million, representing 1.3 million shares. During the six months ended July 3, 2021 and July 4, 2020, we granted PSUs with a total fair value of approximately $14.4 million and $5.4 million, respectively, to key employees.

Share-based compensation expense

During the three and six months ended July 3, 2021, we recorded share-based compensation expense for all awards of $5.3 million and $8.6 million, respectively. During the three and six months ended July 4, 2020, we recorded share-based compensation expense for all awards of $5.2 million and $8.5 million, respectively.

EARNINGS PER COMMON SHARE

EARNINGS PER COMMON SHARE

Basic earnings per common share is computed by dividing net income allocated to common shares by the weighted average number of common shares outstanding. Diluted earnings per common share, if applicable, considers the dilutive effect of common stock equivalents. The reconciliation of the numerator and denominator used for the computation of basic and diluted earnings per common share is as follows (in thousands, except per share data):

Incentive Plan securities excluded from dilution(1)	130		4,358		216		3,338

(1)Represents securities not included in the computation of diluted earnings per common share because their effect would have been anti-dilutive.

We calculate earnings per share using the “two-class” method, whereby unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are “participating securities” and, therefore, these participating securities are treated as a separate class in computing earnings per share. The calculation of earnings per share presented here excludes the income attributable to unvested restricted stock units from the numerator and excludes the dilutive impact of those shares from the denominator. Awards subject to the achievement of performance conditions or market conditions for which such conditions had been met at the end of any of the fiscal periods presented are included in the computation of diluted earnings per common share if their effect was dilutive.

Product Warranties Disclosures [Abstract]

WARRANTY

WARRANTYThe Company offers a number of warranties associated with the products it sells. The specific terms and conditions of these warranties vary depending on the product sold. The Company’s warranty liabilities are undiscounted and adjusted for inflation based on third party actuarial estimates. Factors that affect the Company’s warranty liabilities include the number of units sold, historical and anticipated rates of warranty claims, cost per claim and new product introduction. Warranties are normally limited to replacement or service of defective components for the original customer. Some warranties are transferable to subsequent owners and are generally limited to ten years from the date of manufacture or require pro-rata payments from the customer. A provision for estimated warranty costs is recorded based on historical experience and the Company periodically adjusts these provisions to reflect actual experience. Warranty costs are included within cost of goods sold. The Company assesses the adequacy of the recorded warranty claims and adjusts the amounts as necessary. Separately, upon the sale of a weathertightness warranty in the Commercial segment, the Company records the resulting revenue as deferred revenue, which is included in other accrued expenses and other long-term liabilities on the consolidated balance sheets depending on when the revenues are expected to be recognized.

The following table represents the rollforward of our accrued warranty obligation and deferred warranty revenue activity for the six months ended July 3, 2021 and July 4, 2020 (in thousands):

DEFINED BENEFIT PLANS

Retirement Benefits [Abstract]

DEFINED BENEFIT PLANS

DEFINED BENEFIT PLANS

RCC Pension Plan — With the acquisition of Robertson-Ceco II Corporation (“RCC”) on April 7, 2006, we assumed a defined benefit plan (the “RCC Pension Plan”). Benefits under the RCC Pension Plan are primarily based on years of service and the employee’s compensation. The RCC Pension Plan is frozen and, therefore, employees do not accrue additional service benefits. Plan assets of the RCC Pension Plan are invested in broadly diversified portfolios of government obligations, mutual funds, stocks, bonds, fixed income securities and master limited partnerships.

CENTRIA Benefit Plans — As a result of the CENTRIA Acquisition on January 16, 2015, we assumed noncontributory defined benefit plans covering certain hourly employees (the “CENTRIA Benefit Plans”) and which are closed to new participants. Benefits under the CENTRIA Benefit Plans are calculated based on fixed amounts for each year of service rendered, although benefits accruals for one of the plans previously ceased. Plan assets of the CENTRIA Benefit Plans are invested in fixed income funds. CENTRIA also sponsors postretirement medical and life insurance plans that cover certain of its employees and their spouses (the “OPEB Plans”). Currently, the Company’s policy is to fund the CENTRIA Benefit Plans as required by minimum funding standards of the Internal Revenue Code.

Ply Gem Pension Plans — As a result of the Merger on November 16, 2018, we assumed the Ply Gem Group Pension Plan (the “Ply Gem Plan”) and the MW Manufacturers, Inc Retirement Plan (the “MW Plan”). The Ply Gem Plan was frozen during 1998, and no further increases in benefits for participants may occur as a result of increases in service years or compensation. The MW Plan was frozen for salaried participants during 2004 and non-salaried participants during 2005. No additional participants may enter the plan, but increases in benefits for participants as a result of increase in service years or compensation will occur.

We refer to the RCC Pension Plan, the CENTRIA Benefit Plans, the Ply Gem Plan and the MW Plan collectively as the “Defined Benefit Plans” in this Note.

The following tables set forth the components of the net periodic benefit cost, before tax for the periods indicated (in thousands):

	Defined Benefit Plans

We expect to contribute $3.2 million to the Defined Benefit Plans and $0.7 million to OPEB Plans in the year ending December 31, 2021. Our policy is to fund the CENTRIA Benefit Plans as required by minimum funding standards of the Internal Revenue Code. The contributions to the OPEB Plans by retirees vary from none to 25% of the total premiums paid.

Term Loan Facility due April 2028 and Cash Flow Revolver

On April 12, 2018, Ply Gem Midco entered into a Cash Flow Agreement (the "Current Cash Flow Credit Agreement"), which provides for (i) a term loan facility (the “Existing Term Loan Facility”) in an original aggregate principal amount of $1,755.0 million, issued with a discount of 0.5%, and (ii) a cash flow-based revolving credit facility (the “Existing Cash Flow Revolver” and together with the Existing Term Loan Facility, the “Existing Cash Flow Facilities”) of up to $115.0 million.

On November 16, 2018, the Company entered into an incremental term loan facility in connection with the Merger, which increased the aggregate principal amount of the Existing Term Loan Facility by $805.0 million. The proceeds of this incremental term loan facility were used to, among other things, (a) finance the Merger and to pay certain fees, premiums and expenses incurred in connection therewith, (b) repay in full amounts outstanding under the Pre-merger Term Loan Credit Agreement and the Pre-merger ABL Credit Agreement and (c) repay $325.0 million of borrowings outstanding under the ABL Facility. On November 16, 2018, in connection with the consummation of the Merger, NCI and Ply Gem Midco entered into a joinder agreement with respect to the Existing Cash Flow Facilities, and the Company became the Borrower (as defined in the Current Cash Flow Credit Agreement) under the Existing Cash Flow Facilities.

On April 15, 2021, the Company entered into a Second Amendment to the Current Cash Flow Credit Agreement (the “Second Amendment"), among the Company, the several banks and other financial institutions party thereto (the "Cash Flow Lenders") and JPMorgan Chase Bank, N.A., as administrative agent and collateral agent (the “Cash Flow Agent”), which amended the Current Cash Flow Credit Agreement to, among other things:

•Terminate $92.0 million of commitments by Cash Flow Lenders under the Company’s cash flow-based revolving credit facility of up to $115.0 million, maturing on April 12, 2023 (the “Existing Cash Flow Revolver”) and;

•Replace such commitments with $92.0 million of extended cash flow-based revolving commitments, maturing on April 12, 2026 (the “Extended Cash Flow Revolver” and together with the Existing Cash Flow Revolver, the “ Current Cash Flow Revolver”).

On April 15, 2021, the Company entered into (i) a Third Amendment to Current Cash Flow Credit Agreement (the “Third Amendment”), among the Company, the subsidiary guarantors parties thereto, the Cash Flow Lenders party thereto and the Cash Flow Agent and (ii) an Increase Supplement (the “Increase Supplement”), between the Company and JPMorgan Chase Bank, N.A., as the increasing lender. The Third Amendment amended the Current Cash Flow Credit Agreement to, among other things, refinance the Existing Term Loan Facility in an original aggregate principal amount of $1,755.0 million with Tranche B Term Loans in an aggregate principal amount of approximately $2,491.6 million, maturing on April 12, 2028. The Increase Supplement supplemented the Current Cash Flow Credit Agreement to, among other things, increase the aggregate principal amount of the Tranche B Term Loan Facility by approximately $108.4 million (the “Incremental Tranche B Term Loans”), for a total principal amount of $2,600.0 million (the “Current Term Loan Facility” and together with the Current Cash Flow Revolver, the “Current Cash Flow Facilities”). Proceeds of the Incremental Tranche B Term Loans were used, together with cash on hand, (i) for the redemption of all of the 8.00% Senior Notes (as defined below) (the “Senior Notes Redemption”) and (ii) to pay any fees and expenses incurred in connection with the extension and refinancing of the Company’s senior credit facilities and the Senior Notes Redemption.

In connection with the Third Amendment and the Increase Supplement to the Current Cash Flow Credit Agreement, we incurred $21.8 million and $24.8 million in financing costs for the three and six months ended July 3, 2021, respectively, of which $13.1 million and $13.2 million, respectively, were deferred and will be amortized using the effective interest method.

The Current Term Loan Facility amortizes in nominal quarterly one installments equal to one percent of the aggregate initial principal amount thereof per annum, with the remaining balance payable upon final maturity. The Current Term Loan Facility bears annual interest at a floating rate measured by reference to, at the Company’s option, either (i) an adjusted LIBOR rate (subject to a floor of 0.50%) plus an applicable margin of 3.25% per annum or (ii) an alternate base rate plus an applicable margin of 2.25% per annum. At July 3, 2021, the interest rates on the Current Term Loan Facility were as follows:

	July 3, 2021
Interest rate	3.75	%
Effective interest rate	4.02	%

The Company entered into certain interest rate swap agreements in 2019 and 2021 to effectively convert a portion of its variable rate debt to fixed. See Note 15 — Derivatives.

Loans outstanding under the Current Cash Flow Revolver bear annual interest at a floating rate measured by reference to, at the Company’s option, either (i) an adjusted LIBOR rate (subject to a floor of 0.00%) plus an applicable margin ranging from 2.50% to 3.00% per annum depending on the Company’s secured leverage ratio or (ii) an alternate base rate plus an applicable margin ranging from 1.50% to 2.00% per annum depending on the Company’s secured leverage ratio. There are no amortization payments under the Current Cash Flow Revolver. Additionally, unused commitments under the Current Cash Flow Revolver are subject to a fee ranging from 0.25% to 0.50% per annum depending on the Company’s secured leverage ratio.

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

Subject to certain exceptions, the Current Term Loan Facility is subject to mandatory prepayments in an amount equal to:

•the net cash proceeds of (1) certain asset sales, (2) certain debt offerings and (3) certain insurance recovery and condemnation events; and

•50% of annual excess cash flow (as defined in the Current Cash Flow Credit Agreement), subject to reduction to 25% and 0% if specified secured leverage ratio targets are met to the extent that the amount of such excess cash flow exceeds $10.0 million. For 2020, no payments were required under the excess cash flow calculation.

The obligations under the Current Cash Flow Credit Agreement are guaranteed by each direct and indirect wholly-owned U.S. restricted subsidiary of the Company, subject to certain exceptions, and are secured by:

•a perfected security interest in substantially all tangible and intangible assets of the Company and each subsidiary guarantor (other than ABL Priority Collateral (as defined below)), including the capital stock of each direct material wholly-owned U.S. restricted subsidiary owned by the Company and each subsidiary guarantor, and 65% of the capital stock of any non-U.S. subsidiary held directly by the Company or any subsidiary guarantor, subject to certain exceptions (the “Cash Flow Priority Collateral”), which security interest will be senior to the security interest in the foregoing assets securing the Current ABL Facility; and

•a perfected security interest in the ABL Priority Collateral, which security interest will be junior to the security interest in the ABL Priority Collateral securing the Current ABL Facility.

The Current Cash Flow Revolver includes a financial covenant set at a maximum secured leverage ratio of 7.75:1.00, which will apply if the outstanding amount of loans and drawings under letters of credit which have not then been reimbursed exceeds a specified threshold at the end of any fiscal quarter.

ABL Facility due April 2026

On April 12, 2018, Ply Gem Midco entered into an ABL Credit Agreement (the "Current ABL Credit Agreement"), which provides for an asset-based revolving credit facility (the “Existing ABL Facility”) of up to $360.0 million, consisting of (i) $285.0 million available to U.S. borrowers (subject to U.S. borrowing base availability) (the “ABL U.S. Facility”) and (ii) $75.0 million available to both U.S. borrowers and Canadian borrowers (subject to U.S. borrowing base and Canadian borrowing base availability) (the “ABL Canadian Facility”). The Company and, at their option, certain of their subsidiaries are the borrowers under the Existing ABL Facility.

On October 15, 2018, Ply Gem Midco entered into an incremental asset-based revolving credit facility of $36.0 million, which upsized the Existing ABL Facility to $396.0 million in the aggregate, and with (x) the ABL U.S. Facility being increased from $285.0 million to $313.5 million and (y) the ABL Canadian Facility being increased from $75.0 million to $82.5 million.

On November 16, 2018, Ply Gem Midco entered into an incremental asset-based revolving credit facility of $215.0 million in connection with the Merger, which upsized the Existing ABL Facility to $611.0 million in the aggregate, and with (x) the ABL U.S. Facility being increased from $313.5 million to approximately $483.7 million and (y) the ABL Canadian Facility being increased from $82.5 million to approximately $127.3 million. On November 16, 2018, in connection with the consummation of the Merger, the Company and Ply Gem Midco entered into a joinder agreement with respect to the Existing ABL Facility, and the Company became the Parent Borrower (as defined in the ABL Credit Agreement) under the Existing ABL Facility.

On April 15, 2021, the Company entered into Amendment No. 6 to the Current ABL Credit Agreement, by and among the Company, the subsidiary borrowers party thereto, the several banks and financial institutions party thereto and UBS AG, Stamford Branch, as administrative agent and collateral agent, which amended the ABL Credit Agreement in order to, among other things:

•Terminate the existing revolving commitments of each of the Extending ABL Credit Lenders (as defined in therein), originally maturing on April 12, 2023 (the “Existing ABL Commitments”); and

•Replace the Existing ABL Commitments with an extended revolving commitment of $611.0 million, maturing on April 12, 2026 (the “Current ABL Facility”).

Borrowing availability under the Current ABL Facility is determined by a monthly borrowing base collateral calculation that is based on specified percentages of the value of eligible inventory, eligible accounts receivable and eligible credit card receivables, less certain reserves and subject to certain other adjustments as set forth in the Current ABL Credit Agreement. Availability is reduced by issuance of letters of credit as well as any borrowings. As of July 3, 2021, the Company had the following in relation to the Current ABL Facility (in thousands):

	July 3, 2021
Excess availability	$	403,994
Revolving loans outstanding	160,000
Letters of credit outstanding	40,902

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

The obligations under the Current ABL Credit Agreement are guaranteed by each direct and indirect wholly-owned U.S. restricted subsidiary of the Company, subject to certain exceptions, and are secured by:

•a perfected security interest in all present and after-acquired inventory, accounts receivable, deposit accounts, securities accounts, and any cash or other assets in such accounts and other related assets owned by the Company and the U.S. subsidiary guarantors and the proceeds of any of the foregoing, except to the extent such proceeds constitute Cash Flow Priority Collateral, and subject to certain exceptions (the “ABL Priority Collateral”), which security interest is senior to the security interest in the foregoing assets securing the Current Cash Flow Facilities; and

•a perfected security interest in the Cash Flow Priority Collateral, which security interest will be junior to the security interest in the Cash Flow Collateral securing the Current Cash Flow Facilities.

Additionally, the obligations of the Canadian borrowers under the Current ABL Credit Agreement are guaranteed by each direct and indirect wholly-owned Canadian restricted subsidiary of the Canadian borrowers, subject to certain exceptions, and are secured by substantially all assets of the Canadian borrowers and the Canadian subsidiary guarantors, subject to certain exceptions.

The Current ABL Credit Agreement includes a minimum fixed charge coverage ratio of 1.00:1.00, which is tested only when specified availability is less than 10.0% of the lesser of (x) the then applicable borrowing base and (y) the then aggregate effective commitments under the Current ABL Facility, and continuing until such time as specified availability has been in excess of such threshold for a period of 20 consecutive calendar days.

6.125% Senior Notes due January 2029

On September 24, 2020, the Company issued $500.0 million in aggregate principal amount of 6.125% Senior Notes due January 2029 (“the 6.125% Senior Notes”). Proceeds from the 6.125% Senior Notes were used to repay outstanding amounts under the Company’s Current ABL Facility and Current Cash Flow Revolver. The 6.125% Senior Notes bear interest at 6.125% per annum and will mature on January 15, 2029. Interest is payable semi-annually in arrears on January 15 and July 15 commencing on January 15, 2021. The effective interest rate for the 6.125% Senior Notes was 6.33% as of July 3, 2021, after considering each of the different interest expense components of this instrument, including the coupon payment and the deferred debt issuance costs.

The 6.125% Senior Notes are guaranteed on a senior unsecured basis by each of the Company’s existing and future wholly-owned domestic subsidiaries that guarantee the Company’s obligations under the Current Cash Flow Facilities or the Current ABL Facility (including by reason of being a borrower under the Current ABL Facility on a joint and several basis with the Company or a subsidiary guarantor). The 6.125% Senior Notes are unsecured senior indebtedness and are effectively subordinated to all of the Company’s existing and future senior secured indebtedness, including indebtedness under the Current Term Loan Facility, Current Cash Flow Revolver and Current ABL Facility, and are senior in right of payment to future subordinated indebtedness of the Company.

The Company may redeem the 6.125% Senior Notes in whole or in part at any time as set forth below:

•prior to September 15, 2023, at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to but not including the redemption date, plus the applicable make-whole premium;

•prior to September 15, 2023, up to 40% of the aggregate principal amount with the proceeds of certain equity offerings at a redemption price of 106.125% plus accrued and unpaid interest, if any, to but not including the redemption date;

•on or after September 15, 2023 and prior to September 15, 2024, at a price equal to 103.063% of the principal amount thereof, plus accrued and unpaid interest, if any, to but not including the redemption date;

•on or after September 15, 2024 and prior to September 15, 2025, at a price equal to 101.531% of the principal amount thereof, plus accrued and unpaid interest, if any, to but not including the redemption date; and

•on or after September 15, 2025, at a price equal to 100.000% of the principal amount thereof, plus accrued and unpaid interest, if any, to but not including the redemption date.

Redemption of 8.00% Senior Notes

On April 15, 2021, the Company redeemed the outstanding $645.0 million aggregate principal amount of the 8.00% Senior Notes due April 2026 (the “8.00% Senior Notes”) for $670.8 million using cash on hand and proceeds from the Incremental Tranche B Term Loans. The redemption resulted in a pre-tax loss on extinguishment of debt of $41.9 million during the three and six months ended July 3, 2021, comprising a make-whole premium of $25.8 million and a write-off of $16.1 million in unamortized deferred financing costs.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVES

DERIVATIVES

We utilize derivative instruments, including interest rate swap agreements and foreign currency hedging contracts, to manage our exposure to interest rate risk and currency fluctuations. We only hold such instruments for economic hedging purposes, not for speculative or trading purposes. Our derivative instruments are transacted only with highly rated institutions, which reduces our exposure to credit risk in the event of nonperformance.

Interest Rate Swaps

We are exposed to interest rate risk associated with fluctuations in interest rates on our floating-rate Current Term Loan Facility. The objective in using interest rate derivatives is to manage our exposure to interest rate movements. To accomplish this objective, we have entered into interest rate swap agreements as part of our interest rate risk management strategy. Interest rate swaps involve the receipt of variable amounts from a counterparty in exchange for the company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

On a monthly basis, we net settle with our swap counterparties for the difference between the fixed rate specified in each swap agreement and the variable rate as applied to the notional amount of the swap.

In May 2019, the Company entered into four-year interest rate swaps to mitigate variability in forecasted interest payments on $1,500.0 million of the Company’s Current Term Loan Facility. The interest rate swaps effectively converted a portion of the floating rate interest payment into a fixed rate interest payment. Three interest rate swaps each covered of notional amount of $500.0 million. The Company designated the interest rate swaps as qualifying hedging instruments and accounted for these derivatives as cash flow hedges.

As discussed in Note 14 — Long-Term Debt, the Company refinanced its Term Loan Facility. Contemporaneously with the refinancing on April 15, 2021, we completed a series of transactions to modify our interest rate swap positions as follows: (i) we de-designated all existing interest rate swaps as cash flow hedges; (ii) we terminated two existing interest rate swaps with a notional value of $500 million each; (iii) we entered into two receive-fixed interest rate swaps with a notional amount of $250 million each, which are designed to offset the terms of an existing, active interest rate swap with a notional amount of $500 million; and (iv) we entered into two pay-fixed interest rate swaps with a notional amount of $750 million each, effectively blending the liability position of our existing interest rate swap agreements into the new swaps and extending the term of our hedged position to April 2026.

The amount remaining in accumulated other comprehensive loss for the de-designated and terminated swaps at the de-designation date was approximately $65.5 million and will be amortized as an increase to interest expense over the effective period of the original swap agreements.

The new receive-fixed interest rate swaps will remain undesignated to economically offset the now undesignated existing, active swap. The new receive-fixed and the existing, active swaps mature on July 12, 2023. Cash settlements related to these receive-fixed interest rate swaps will offset and are classified as operating activities in the consolidated statements of cash flows.

The new pay-fixed interest rate swaps also qualify as hybrid instruments in accordance with ASC 815, Derivatives and Hedging, consisting of a loan and an embedded at-market derivative that was designated as a cash flow hedge. The loan is accounted for at amortized cost over the life of the swap while the embedded at-market derivative is accounted for at fair value. The new swaps are indexed to one-month LIBOR and will be net settled on a monthly basis with the counterparty for the difference between the fixed rate of 2.0369% and 2.0340%, respectively, and the variable rate based upon one-month LIBOR (subject to a floor of 0.5%) as applied to the notional amount of the swaps. In connection with the transactions discussed above, no cash was exchanged between the Company and the counterparty. The liability of the terminated interest rate swaps as well as the inception value of the receive-fixed interest rate swap was blended into the new pay-fixed interest rate swap. The cash flows related to the portion treated as debt will be classified as financing activities in the consolidated statements of cash flows while the portion treated as an at-market derivative will be classified as operating activities.

The key terms of interest rate swaps are as follows (amounts in thousands):

			July 3, 2021			December 31, 2020
Effective Date	Fixed Rate Paid (Received)		Notional Amount		Status	Notional Amount		Status	Maturity Date
Entered into May 2019:

April 15, 2021	2.0340	%	750,000		Active				April 15, 2026
April 15, 2021	(2.1680)	%	(250,000)		Active				July 12, 2023
April 15, 2021	(2.1680)	%	(250,000)		Active				July 12, 2023
			$	1,500,000		$	1,500,000

Our interest rate swap agreements, excluding the portion treated as debt, are recognized at fair value in the consolidated balance sheets and are valued using pricing models that rely on market observable inputs such as yield curve data, which are classified as Level 2 inputs within the fair value hierarchy.

Foreign Currency Hedging Contracts

In December 2020, the Company entered into forward contracts to hedge approximately $66.0 million of its 2021 non-functional currency inventory purchases. These forward contracts were established to protect the Company from variability in cash flows attributable to changes in the U.S. dollar relative to the Canadian dollar. The forward contracts are highly correlated to the changes in the U.S. dollar relative to the Canadian dollar. Unrealized gains and losses on these contracts are designated as effective or ineffective. The effective portion of such gains or losses is recorded as a component of accumulated other comprehensive income or loss, while the ineffective portion of such gains or losses is recorded as a component of cost of goods sold. Future realized gains and losses in connection with each inventory purchase will be reclassified from accumulated other comprehensive income or loss to cost of goods sold. The gains and losses on the derivative contracts that are reclassified from accumulated other comprehensive income or loss to current period earnings are included in the line item in which the hedged item is recorded in the same period the forecasted transaction affects earnings.

During the three months ended July 3, 2021, the Company entered into forward contracts to hedge approximately $20.2 million of its 2022 non-functional currency inventory purchases. Similar to the December 2020 contracts described above, these contracts were established to protect the Company from variability in cash flows attributable to changes in the U.S dollar relative to the Canadian dollar. All of the Company’s foreign currency forward contracts are designated as qualifying hedging instruments and are accounted for as cash flow hedges in accordance with ASC 815, Derivatives and Hedging.

During the three and six months ended July 3, 2021, the Company realized a loss of approximately $0.4 million and $0.5 million, respectively within cost of goods sold in the consolidated statements of operations based on the foreign currency forward contracts described above. The changes in fair values of derivatives that have been designated and qualify as cash flow hedges are recorded in accumulated other comprehensive income or loss and are reclassified into cost of goods sold in the same period the hedged item affects earnings. Due to the high degree of effectiveness between the hedging instruments and the underlying exposures being hedged, fluctuations in the value of the derivative instruments are generally offset by changes in the fair value or cash flows of the underlying exposures being hedged. The changes in the fair value of derivatives that do not

qualify as effective are immediately recognized in earnings. As of July 3, 2021, the Company had a hedge liability of approximately $1.3 million and a loss of approximately $1.4 million in accumulated other comprehensive loss on the consolidated balance sheets. No hedge liability or asset or deferred gain or loss in accumulated other comprehensive loss existed as of December 31, 2020 related to the forward contracts.

STOCK REPURCHASE PROGRAM

STOCK REPURCHASE PROGRAM

The Company announced that its Board of Directors authorized new stock repurchase programs for the repurchase of up to $50.0 million of the Company’s outstanding Common Stock on October 10, 2017 and March 7, 2018, for a cumulative total of $100.0 million. Under these repurchase programs, the Company is authorized to repurchase shares at times and in amounts that it deems appropriate in accordance with all applicable securities laws and regulations. Shares repurchased pursuant to the repurchase programs are usually retired. There is no time limit on the duration of the programs. Following repurchases made during the three months ended July 4, 2020, no authorized amount remained available under the program announced on October 10, 2017.

During the six months ended July 3, 2021, there were no stock repurchases under the stock repurchase programs. The Company repurchased 1.1 million shares for $6.4 million under the stock repurchase programs during the six months ended July 4, 2020. As of July 3, 2021, $49.1 million remained available for stock repurchases under the program announced on March 7, 2018. The timing and method of any repurchases, which will depend on a variety of factors, including market conditions, are subject to results of operations, financial conditions, cash requirements and other factors, and may be suspended or discontinued at any time.

During the six months ended July 3, 2021 and July 4, 2020, the Company withheld approximately 0.1 million and 0.1 million shares, respectively, of stock to satisfy minimum tax withholding obligations arising in connection with the vesting of stock awards, which are included in treasury stock purchases in the consolidated statements of stockholders’ equity.

During the six months ended July 3, 2021 and July 4, 2020, the Company cancelled approximately 0.1 million and 1.2 million shares that had been previously withheld to satisfy minimum tax withholding obligations arising in connection with the vesting of stock awards and shares repurchased under the stock repurchase programs. The cancellations resulted in $1.5 million and $6.9 million decreases in both treasury stock and additional paid in capital during the six months ended July 3, 2021 and July 4, 2020, respectively.

FAIR VALUE OF FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

FAIR VALUE OF FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, restricted cash, trade accounts receivable and accounts payable approximate fair value as of July 3, 2021 and December 31, 2020, respectively, because of their relatively short maturities. The carrying amounts of the indebtedness under the Current ABL Facility and Current Cash Flow Revolver approximate fair value as the interest rates are variable and reflective of market rates. At July 3, 2021, there was $160.0 million of borrowings outstanding under the Current ABL Facility and no outstanding indebtedness under the Current Cash Flow Revolver. The fair values of the remaining financial instruments not currently recognized at fair value on our consolidated balance sheets at the respective period ends were (in thousands):

	July 3, 2021				December 31, 2020
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Term Loan Facility	$	2,593,500	$	2,589,610	$	2,497,967	$	2,485,477
8.00% Senior Notes	—		—		645,000		674,025
6.125% Senior Notes	500,000		536,250		500,000		530,000

The fair value of the term loan facility was based on recent trading activities of comparable market instruments, which are level 2 inputs and the fair values of the 8.00% and 6.125% senior notes were based on quoted prices in active markets for the identical liabilities, which are level 1 inputs.

Fair Value Measurements

ASC Subtopic 820-10, Fair Value Measurements and Disclosures, requires us to use valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized as follows:

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

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

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

The following is a description of the valuation methodologies used for assets and liabilities measured at fair value. There have been no changes in the methodologies used as of July 3, 2021 and December 31, 2020.

Money market: Money market funds have original maturities of three months or less. The original cost of these assets approximates fair value due to their short-term maturity.

Mutual funds: Mutual funds are valued at the closing price reported in the active market in which the mutual fund is traded. 

Assets held for sale: Assets held for sale are valued based on current market conditions, prices of similar assets in similar condition and expected proceeds from the sale of the assets.

Deferred compensation plan liability: Deferred compensation plan liability is comprised of phantom investments in the deferred compensation plan and is valued at the closing price reported in the active markets in which the money market and mutual funds are traded.

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

Foreign currency hedges: The fair value of the foreign currency forward contracts are estimated using industry standard valuation models using market-based observable inputs, including spot rates, forward points, interest rates and volatility inputs (Level 2).

The following tables summarize information regarding our financial assets and liabilities that are measured at fair value on a recurring basis as of July 3, 2021 and December 31, 2020, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (in thousands):

Income Tax Disclosure [Abstract]

INCOME TAXES

INCOME TAXES

Under FASB ASC 740-270, Income Taxes - Interim Reporting, each interim period is considered an integral part of the annual period and tax expense is measured using an estimated annual effective tax rate. Estimates of the annual effective tax rate at the end of interim periods are, of necessity, based on evaluations of possible future events and transactions and may be subject to subsequent refinement or revision. The Company calculates its quarterly tax provision consistent with the guidance provided by ASC 740-270, whereby the Company forecasts its estimated annual effective tax rate then applies that rate to its year-to-date ordinary pre-tax book income (loss). In addition, the Company excludes jurisdictions with a projected loss for the year or the year-to-date ordinary loss where the Company cannot recognize a tax benefit from its estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections. In addition to the tax resulting from applying the estimated annual effective tax rate to pre-tax book income (loss), the Company includes certain items treated as discrete events to arrive at an estimated effective tax rate. Future changes in the forecasted annual income (loss) projections, tax rate changes, or discrete tax items could result in significant adjustments to quarterly income tax expense in future periods in accordance with ASC 740-270.

For the six months ended July 3, 2021, the Company’s estimated annual effective income tax of ordinary forecasted pre-tax book income was approximately 31.9%, which varied from the statutory rate primarily due to state income tax expense, valuation allowances, and foreign income taxes. For the six months ended July 3, 2021, the effective tax rate was (3.9)%, which varied from the annual effective tax rate due to discrete items recorded during the period, including interest recorded on unrecognized tax benefits, adjustments to state income tax rates, and stock compensation.

Valuation allowance

As of July 3, 2021, the Company remained in a valuation allowance position, in the amount of $12.0 million, against its deferred tax assets for certain state jurisdictions of certain entities as it is currently deemed “more likely than not” that the benefit of such net tax assets will not be utilized as the Company continues to be in a three-year cumulative loss position for these state jurisdictions. The Company will continue to monitor the positive and negative factors for these jurisdictions and make further changes to the valuation allowances as necessary.

Unrecognized tax benefits

Despite the Company’s belief that its tax return positions are consistent with applicable tax laws, the Company believes that certain positions could be challenged by taxing authorities. The Company’s tax reserves reflect the difference between the tax benefit claimed on tax returns and the amount recognized in the consolidated financial statements. These reserves have been established based on management’s assessment as to potential exposure attributable to permanent differences as well as interest and penalties applicable to both permanent and temporary differences. The tax reserves are reviewed periodically and adjusted in light of changing facts and circumstances, such as progress of tax audits, lapse of applicable statutes of limitations and changes in tax law. The Company is currently under examination by various taxing authorities. During the six months ended July 3, 2021, the tax reserves increased by approximately $6.2 million. The increase is primarily due to a new uncertain tax benefit and additional interest expense related to previously recorded unrecognized tax benefits.

The liability for unrecognized tax benefits as of July 3, 2021 was approximately $17.9 million and is recorded in other long-term liabilities in the consolidated balance sheet.

CARES Act

Under the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) that was signed into law on March 27, 2020, the Company elected to defer employer side social security payments for approximately $19.9 million as of December 31, 2020, $10 million of which is recorded in current liabilities on the consolidated balance sheet. Approximately $10 million of the deferral will be paid by December 31, 2021 and the remainder will be paid by December 31, 2022.

Segment Reporting [Abstract]

SEGMENT INFORMATION

SEGMENT INFORMATION

Operating segments are defined as components of an enterprise that engage in business activities for which discrete financial information is available and is evaluated on a regular basis by the chief operating decision maker to make decisions regarding the allocation of resources to the segment and assess the performance of the segment. The Company has three reportable segments: Windows, Siding and Commercial.

These operating segments follow the same accounting policies used for our consolidated financial statements. We evaluate a segment’s performance on a U.S. GAAP basis primarily upon operating income before corporate expenses.

Corporate assets consist primarily of cash, investments, prepaid expenses, current and deferred taxes and property, plant and equipment associated with our headquarters in Cary, North Carolina and office in Houston, Texas. These items (and income and expenses related to these items) are not allocated to the operating segments. Corporate unallocated expenses primarily include share-based compensation expenses, restructuring charges, acquisition-related costs, and other expenses related to executive, legal, finance, tax, treasury, human resources, information technology and strategic sourcing, and corporate travel expenses. Additional unallocated amounts primarily include non-operating items such as interest income, interest expense, loss on extinguishment of debt and other income (expense).

The following table represents summary financial data attributable to the segments for the periods indicated (in thousands):

CONTINGENCIES

Commitments and Contingencies Disclosure [Abstract]

CONTINGENCIES

CONTINGENCIES

As a manufacturer of products primarily for use in building construction, the Company is inherently exposed to various types of contingent claims, both asserted and unasserted, in the ordinary course of business. As a result, from time to time, the Company and/or its subsidiaries become involved in various legal proceedings or other contingent matters arising from claims or potential claims arising out of its operations and businesses that cover a wide range of matters, including, among others, environmental, contract, employment, intellectual property, securities, personal injury, property damage, product liability, warranty, and modification, adjustment or replacement of component parts or units sold, which may include product recalls. The Company insures (or self insures) against these risks to the extent deemed prudent by its management and to the extent insurance is available. The Company regularly reviews the status of ongoing proceedings and other contingent matters along with legal counsel. Liabilities for such items are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably estimated. Liabilities are adjusted when additional information becomes available. Management believes that the ultimate disposition of these matters will not have a material adverse effect on the Company’s results of operations, financial position or cash flows. However, such matters are subject to many uncertainties and outcomes and are not predictable with assurance.

Further, due to the lack of adequate information and the potential impact of present regulations and any future regulations, there are certain circumstances in which no range of potential exposure may be reasonably estimated. Also, it is not possible to ascertain the ultimate legal and financial liability with respect to certain contingent liabilities, including lawsuits, and therefore no such estimate has been made as of July 3, 2021.

Environmental

The Company’s operations are subject to various federal, state, local and foreign environmental, health and safety laws. Among other things, these laws regulate the emissions or discharge of materials into the environment; govern the use, storage, treatment, disposal and management of hazardous substances and wastes; protect the health and safety of its employees and the end-users of its products; regulate the materials used in its products; and impose liability for the costs of investigating and remediating (as well as other damages resulting from) present and past releases of hazardous substances. Violations of these laws or of any conditions contained in environmental permits could result in substantial fines or penalties, injunctive relief, consent orders, requirements to install pollution controls or other abatement equipment, or civil sanctions.

The Company could be held liable for costs to investigate, remediate or otherwise address contamination at any real property it has ever owned, operated or used as a disposal site, or at other sites where we or predecessors may have released hazardous materials. The Company could incur fines, penalties or sanctions or be subject to third-party claims, including indemnification claims, for property damage, personal injury or otherwise as a result of violations of (or liabilities under) environmental, health and safety laws, or in connection with releases of hazardous or other materials.

MW Manufacturers Inc. (“MW”), a subsidiary of Ply Gem Industries, Inc., entered into a September 2011 Administrative Order on Consent with the EPA under the Corrective Action Program to address known releases of hazardous substances at MW’s Rocky Mount, Virginia property. A Phase I RCRA Facility Investigation (“RFI”) was submitted to the Virginia Department of Environmental Quality (“VDEQ”) in December 2015, and a Phase II RFI and the Human Health Risk Assessment and Baseline Ecological Risk Assessment were submitted in October 2018. A Limited Corrective Measures Study (“LCMS”) based on the investigations was submitted to the VDEQ for review and approval in September 2019. The VDEQ concurred with the LCMS and prepared a Statement of Basis, which was published for a 30-day public review and comment in April 2021. Upon completion, the VDEQ issued its Final Decision and Response to Comments on May 19, 2021 to approve the final remedy proposed in the LCMS. The Company has recorded a liability of $4.5 million for this MW site, of which $1.0 million is in other current liabilities in the Company’s consolidated balance sheet as of July 3, 2021. 

The EPA is investigating groundwater contamination at a Superfund site in York, Nebraska, referred to as the PCE/TCE Northeast Contamination Site (“PCE/TCE Site”). Kroy Building Products, Inc. (“KBP”), a subsidiary of Ply Gem Industries, Inc., has been identified as a potentially responsible party (“PRP”) at the site and has liability for investigation and remediation costs associated with the contamination. On May 17, 2019, KBP and an unrelated respondent, Kroy Industries, Inc., entered into an Administrative Settlement Agreement and Order on Consent with the EPA to conduct a Remedial Investigation/Feasibility Study (“RI/FS”) of the PCE/TCE Site. A final RI/FS Work Plan was submitted to EPA in November 2019 and approved in December 2019. RI Phase I field sampling and mobile laboratory analysis was initiated in Spring 2020. After a delay due to the COVID-19 pandemic, Phase 2 of the R1 Phase field work was completed in May 2021, and results are being analyzed to determine scope of additional investigation. The Company has recorded a liability of $4.4 million within other current liabilities in its consolidated balance sheet as of July 3, 2021. The Company will adjust our remediation liability in future periods, if necessary, as the RI/FS progresses or if additional requirements are imposed. The Company may be able to recover a portion of costs incurred in connection with the PCE/TCE Site from other potentially responsible parties, though there is no assurance we would receive any funds.

Based on current information, the Company is not aware of any environmental compliance obligations, claims or investigations that will have a material adverse effect on its results of operations, cash flows or financial position except as otherwise disclosed in the Company’s consolidated financial statements. However, there can be no guarantee that previously known or newly discovered matters will not result in material costs or liabilities.

Litigation

The Company believes it has valid defenses to the outstanding claims discussed below and will vigorously defend all such claims; however, litigation is subject to many uncertainties and there cannot be any assurance that the Company will ultimately prevail or, in the event of an unfavorable outcome or settlement of litigation, that the ultimate liability would not be material and would not have a material adverse effect on the business, results of operations, cash flows or financial position of the Company.

In November 2018, Aurora Plastics, LLC (“Aurora”) initiated an arbitration demand against Atrium Windows and Doors, Inc., Atrium Extrusion Systems, Inc., and North Star Manufacturing (London) Ltd. (collectively, “Atrium”) pursuant to a Third Amended and Restated Vinyl Compound and Supply Agreement dated as of December 22, 2016. A settlement was reached in this case during the fourth quarter of 2019. The Company has a $3.9 million liability related to the settlement, of which $2.3 million is in other current liabilities in the Company’s consolidated balance sheet as of July 3, 2021.

On November 14, 2018, an individual stockholder, Gary D. Voigt, filed a putative class action Complaint in the Delaware Court of Chancery against Clayton Dubilier & Rice, LLC (“CD&R”), Clayton, Dubilier & Rice Fund VIII, L.P. (“CD&R Fund VIII”), and certain directors of the Company. Voigt purports to assert claims on behalf of himself, on behalf of a class of other similarly situated stockholders of the Company, and derivatively on behalf of the Company, the nominal defendant. An Amended Complaint was filed on April 11, 2019. The Amended Complaint asserts claims for breach of fiduciary duty and unjust enrichment against CD&R Fund VIII and CD&R, and for breach of fiduciary duty against twelve director defendants in connection with the Merger. Defendants moved to dismiss the Amended Complaint and, on February 10, 2020, the court denied the motions except as to four of the director defendants. Voigt seeks damages in an amount to be determined at trial.

Other contingencies

The Company’s imports of fabricated structural steel (“FSS”) from its Mexican affiliate, Building Systems de Mexico S.A. de C.V. (“BSM”) were subject to antidumping (“AD”) and countervailing duty (“CVD”) tariff proceedings before the U.S. Department of Commerce (“DOC”) and the U.S. International Trade Commission (“USITC”). The proceedings were initiated in February 2019 by the American Institute of Steel Construction against FSS being imported into the USA from Mexico, Canada, and China. In 2019, the DOC issued preliminary tariff rates and in 2020 finalized CVD and AD tariff rates of 0% and 8.47%, respectively, for the Company’s imports of FSS from BSM. However, in February 2020, in a 3 to 2 vote, the USITC concluded there was no injury or threat of injury to the domestic FSS industry. In March 2020 the USITC opinion was published in the Federal Register, ceasing the Company’s requirement to pay the AD and CVD tariffs. The Company received full reimbursement for the $4.1 million in tariffs previously deposited with United States Customs and Border Protection and recorded a reduction in costs of sales during the fiscal year ended December 31, 2020. This matter has been appealed and the Company will continue to vigorously advocate its position that its import of FSS from BSM should not be subject to any CVD or AD tariffs.

Accounts Receivables and Related Allowance

The Company reports accounts receivable net of the allowance for expected credit losses. Trade accounts receivable are the result of sales of vinyl windows, aluminum windows, vinyl siding, metal siding, injection molded products, metal building products, insulated metal panels, metal coating, and other products and services to customers throughout the United States and Canada and affiliated territories, including international builders who resell to end users. Sales are primarily denominated in U.S. dollars. Credit sales do not normally require a pledge of collateral; however, various types of liens may be filed to enhance the collection process and we require payment prior to shipment for certain international shipments.

The Company establishes provisions for expected credit losses based on the Company’s assessment of the collectability of amounts owed to us by our customers. Such provisions are included in selling, general and administrative expenses. In establishing these reserves, the Company considers changes in the financial position of a customer, age of the accounts receivable balances, availability of security, unusual macroeconomic conditions, lien rights and bond rights as well as disputes, if any, with our customers. Our allowance for credit losses reflects reserves for customer receivables to reduce receivables to amounts expected to be collected. Interest on delinquent accounts receivable is included in the trade accounts receivable balance and recognized as interest income when earned and collectability is reasonably assured. Uncollectible accounts are written off when a settlement is reached for an amount that is less than the outstanding historical balance, all collection efforts have been exhausted, and/or any legal action taken by the Company has concluded.

Net Sales

Net Sales

The Company enters into contracts that pertain to products, which are accounted for as separate performance obligations and are typically one year or less in duration. Given the nature of the Company's sales arrangements, we are not required to exercise significant judgment in determining the timing for the satisfaction of performance obligations or the transaction price. Revenue is measured as the amount of consideration expected to be received in exchange for our products. Revenue is generally recognized when the product has shipped from our facility and control has transferred to the customer. For a portion of our business, when we process customer owned material, control is deemed to transfer to the customer as the processing is being completed.

The Company’s revenues are adjusted for variable consideration, which includes customer volume rebates and prompt payment discounts. The Company measures variable consideration by estimating expected outcomes using analysis and inputs based upon anticipated performance, historical data, and current and forecasted information. Customer returns are recorded as a reduction to sales on an actual basis throughout the year and also include an estimate at the end of each reporting period for future customer returns related to sales recorded prior to the end of the period. The Company generally estimates customer returns based upon the time lag that historically occurs between the sale date and the return date while also factoring in any new business conditions that might impact the historical analysis such as new product introduction. Measurement of variable consideration is reviewed by management periodically and revenue is adjusted accordingly. We do not have significant financing components. The Company recognizes installation revenue, primarily within the stone veneer business, over the period for which the stone is installed, which is typically a very short duration.

Shipping and handling activities performed by us are considered activities to fulfill the sales of our products. Amounts billed for shipping and handling are included in net sales, while costs incurred for shipping and handling are included in cost of sales.

In accordance with certain contractual arrangements, we receive payment from our customers in advance related to performance obligations that are to be satisfied in the future and recognize such payments as deferred revenue, primarily related to the Company’s weathertightness warranties (see Note 12 — Warranty).

A portion of the Company’s revenue, exclusively within the Commercial segment, includes multiple-element revenue arrangements due to multiple deliverables. Each deliverable is generally determined based on customer-specific manufacturing and delivery requirements. Because the separate deliverables have value to the customer on a stand-alone basis, they are typically considered separate units of accounting. A portion of the entire job order value is allocated to each unit of accounting. Revenue allocated to each deliverable is recognized upon shipment. The Company uses estimated selling price (“ESP”) based on underlying cost plus a reasonable margin to determine how to separate multiple-element revenue arrangements into separate units of accounting, and how to allocate the arrangement consideration among those separate units of accounting. The Company determines ESP based on normal pricing and discounting practices.

Adopted Accounting Pronouncements and Recent Accounting Pronouncements

Adopted Accounting Pronouncements

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and also improves consistent application of and simplifies U.S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. Effective January 1, 2021, the Company adopted this guidance. The application of ASU 2019-12 did not have a material effect on the consolidated financial statements.

Recent Accounting Pronouncements

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, which provides optional guidance to ease the potential burden in accounting for reference rate reform on financial reporting. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope, which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the reference rate transition. The amendments in these ASUs are elective, apply to all entities that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of rate reform, and may be adopted as of March 12, 2020 through December 31, 2022. The Company is evaluating the impact of electing to apply the amendments.

Leases

The Company leases certain manufacturing, warehouse and distribution locations, vehicles and equipment, including fleet vehicles. Many of these leases have options to terminate prior to or extend beyond the end of the term. The exercise of the majority of lease renewal options is at the Company’s sole discretion. Some lease agreements have variable payments, the majority of which are real estate agreements in which future increases in rent are based on an index. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company accounts for lease and non-lease components as a single lease component for all leases other than leases of durable tooling. The Company excludes leases with an initial term of 12 months or less from the consolidated balance sheets and recognizes related lease payments in the consolidated statements of operations on a straight-line basis over the lease term.

Operating lease liabilities are recognized based on the present value of the future minimum lease payments over the reasonably expected holding period at the commencement date of the leases. Few of the Company’s lease contracts provide a readily determinable implicit rate. For these contracts, an estimated incremental borrowing rate (“IBR”) is utilized, based on information available at the inception of the lease. The incremental borrowing rate represents an estimate of the interest rate we would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of the lease.

Accounting for leases may require judgment, including determining whether a contract contains a lease, the incremental borrowing rates to utilize for leases without a stated implicit rate, the reasonably certain holding period for a leased asset, and the allocation of consideration to lease and non-lease components. The allocation of the lease and non-lease components for leases of durable tooling is based on the Company’s best estimate of standalone price.

Fair Value Measurements

Fair Value Measurements

ASC Subtopic 820-10, Fair Value Measurements and Disclosures, requires us to use valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized as follows:

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

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

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

The following is a description of the valuation methodologies used for assets and liabilities measured at fair value. There have been no changes in the methodologies used as of July 3, 2021 and December 31, 2020.

Money market: Money market funds have original maturities of three months or less. The original cost of these assets approximates fair value due to their short-term maturity.

Mutual funds: Mutual funds are valued at the closing price reported in the active market in which the mutual fund is traded. 

Assets held for sale: Assets held for sale are valued based on current market conditions, prices of similar assets in similar condition and expected proceeds from the sale of the assets.

Deferred compensation plan liability: Deferred compensation plan liability is comprised of phantom investments in the deferred compensation plan and is valued at the closing price reported in the active markets in which the money market and mutual funds are traded.

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

Foreign currency hedges: The fair value of the foreign currency forward contracts are estimated using industry standard valuation models using market-based observable inputs, including spot rates, forward points, interest rates and volatility inputs (Level 2).
