Independent Auditors’ Report

The Board of Directors Worthington Armstrong Venture:

We have audited the accompanying consolidated financial statements of Worthington Armstrong Venture and its subsidiaries, which comprise the consolidated balance sheets as of December 31, 2019 and 2018, and the related consolidated statements of income and comprehensive income, partners’ deficit, and cash flows for each of the years in the three year period ended December 31, 2019, and the related notes to the consolidated financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with U.S. generally accepted accounting principles; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditors’ judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Worthington Armstrong Venture and its subsidiaries as of December 31, 2019 and 2018, and the results of their operations and their cash flows for each of the years in the three year period ended December 31, 2019, in accordance with U.S. generally accepted accounting principles.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, in the year ended December 31, 2019, the Company adopted new accounting guidance Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, and the related Accounting Standards Updates using the modified retrospective transition method. Our opinion is not modified with respect to this matter.

Its business is to manufacture and market suspension systems for commercial and residential ceiling marketsthroughouttheworld.TheCompanyhasmanufacturingplantslocatedthroughouttheUnitedStates, following the disposition of all international manufacturing facilities to Knauf International GmbH as disclosedbelow.

On November 17, 2017, Armstrong World Industries, Inc. (AWI) entered into a Share Purchase Agreement (the Purchase Agreement) with Knauf International GmbH (Knauf) to sell certain subsidiaries comprising its business in Europe, the Middle East, Africa (EMEA) and the Pacific Rim. The sale also included the corresponding businesses and operations of the Company, and was approved by both Armstrong and Worthington. The consideration to be paid by Knauf for the Company’s businesses was approximately $92,000,subjecttocertainadjustmentsasprovidedinthePurchaseAgreement,includingadjustmentsbased on the economic impact of any required regulatory remedies and a working capitaladjustment.

On July 18, 2018, AWI entered into an amendment to the above Purchase Agreement, pursuant to which KnaufagreedtoirrevocablyandunconditionallypayAWI(i)$250,000onAugust1,2018,and(ii)$80,000 onSeptember15,2018,if,priortosuchdate(A)anycompetitionconditionhasnotbeensatisfied,or(B)the closing has not yet occurred.

(b) RevenueRecognition

The Company recognizes revenue upon transfer of control of manufactured products to the customer, which typically occurs upon shipment. The main performance obligation to customers is the delivery of products in accordance with purchase orders. Each purchase order confirms the transaction price fortheproductspurchasedunderthearrangement.Directshipmentstobuildingmaterialsdistributors, homecenters,directcustomersandretailersrepresentthemajorityofsalestransactions.Standardsales terms are Free On Board (“FOB”) shipping point; however, the Company does have minimal sales termsthatareFOBdestination.Atthepointofshipment,thecustomerisrequiredtopayundernormal sales terms, which in most cases are 45 days or less, with no material financing components. While the majority of the Company’s revenue is derived from the sale of standard products, the Company also manufactures and sells customized ceiling products. The manufacturing cycle for these products is typicallyshort.

The Company’s products are sold with normal and customary return provisions. We provide limited warranties for defects in materials or factory workmanship, sagging and warping, and certain other manufacturing defects. Warranties are not sold separately to customers, and product warranties place certain requirements on the purchaser, including installation and maintenance in accordance with writteninstructions.Inadditiontothewarrantyprogram,undercertainlimitedcircumstances,wewill occasionally, at our sole discretion, provide a customer accommodation repair or replacement. Warranty repairs and replacements are most commonly made by professional installers employed by or affiliated with our independent distributors. Sales returns and warranty claims have historicallynot been material and do not constitute separate performanceobligations.

We often offer incentive programs to our customers, primarily volume rebates and promotions. The majority of our rebates are designated as a percentage of annual customer purchases. We estimate the amountofrebatesbasedonactualsalesfortheperiodandaccruefortheprojectedincentiveprograms costs. We record the costs of rebate accruals as a reduction to our revenue. Other sales discounts, including early pay promotions, are deducted immediately from the salesinvoice.

Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net basis and, therefore, are excluded from revenues in the consolidated statements of income and comprehensive income.

(c) Derivative Instruments and HedgingActivities

The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. For derivatives designated in hedging relationships, changes in the fair value are recognized in accumulated other comprehensive income, to the extent the derivative is effective at offsetting the changes in cash flows being hedged until the hedged item affects earnings. For derivatives not designated as hedges or that do not meet the criteria for hedge accounting, all changes in fair value are recorded immediately to profit or loss.

(d) Advertising Costs

The Company recognizes advertising expense as incurred. Advertising expense was $1,386, $1,491, and $1,243 for the years ended December 31, 2019, 2018, and 2017 respectively.

(e) Research and DevelopmentExpenditures

The Company recognizes research and development expense as expenditures are incurred. Total research and development expense was $3,913, $3,997, and $4,653 for the years ended December31, 2019, 2018, and 2017respectively.

(f) Taxes

The Company is a general partnership in the United States, and accordingly, generally, U.S. federal andstateincometaxesaretheresponsibilityofthetwogeneralpartners.TheCompanyrecognizesthe effect of uncertain income tax positions only if those positions are more likely than not of being sustained.Recognizedincometaxbenefitsaremeasuredatthelargestamountthatisgreaterthan50% likely of being

realized. Changes in recognition or measurement are reflected in the period in which the change in judgmentoccurs.

(g) Trade AccountsReceivable

Tradeaccountsreceivablearerecordedattheinvoicedamountanddonotbearinterest.TheCompany maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio, as deemed necessary. In establishing the required allowance, management considers historicallosses,currentreceivablesaging,andexistingindustryandnationaleconomicdata.Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to itscustomers.

(h) Inventories

Inventories are valued at the lower of cost and net realizable value. Cost is determined on the first-in, first-out method.

(i) Long-LivedAssets

Property, plant, and equipment are stated at cost, with accumulated depreciation and amortization deductedtoarriveatnetbookvalue.Depreciationchargesaredeterminedgenerallyonthestraight-line basis over the useful lives as follows: buildings, 30 years; machinery and equipment, 5 to 15 years; andleaseholdimprovementsovertheshorterof10yearsorthelifeofthelease.Impairmentlossesare recorded when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. If an impairment exists, the asset is reduced to fairvalue.

(j) Goodwill

Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquiredinapurchasebusinesscombination.Goodwillistestedforimpairmentatleastannually.The impairment tests performed in 2019, 2018, and 2017 did not result in an impairment ofgoodwill.

(k) Recently Adopted AccountingStandards

InMay2014,theFASBissuedASU2014-09,RevenuefromContractswithCustomers,whichrequires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to a customer. Revenue is recognized in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. A company also is required to disclose sufficient quantitative and qualitative information to enable users of financial statementstounderstandthenature,amount,timing,anduncertaintyofrevenueandcashflowsarising from contracts with customers. The FASB also has issued several amendments to the standard,which are intended to promote a more consistent interpretation and application of the principles outlined in thestandard.

Effective January 1, 2019, the Company adopted the provisions of ASU 2014-09 using the modified retrospective transition method. Substantially all of our revenues from contracts with customers are recognizedfromthesaleofproductswithstandardshippingterms,salesdiscountsandwarranties.The Company will continue to record revenue at a single point in time when control of the product is transferred to the customer, which is determined to be generally when the product is shipped to the customer. Adoption of the standard did not have a material impact to our financial condition, results ofoperationsorcashflowsastheamountandtimingofsubstantiallyallofourrevenueswillcontinue to be recognized at a point intime.

(l) Recently Issued AccountingStandards

In February 2016, the FASB issued ASU 2016-02, Leases, which amends accounting for leases,most notably by requiring a lessee to recognize the assets and liabilities that arise from a lease agreement. Specifically, this new guidance will require lessees to recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term, withlimitedexceptions.In2019,theFASBapprovedaproposaltodefertheeffectivedateforprivate companies to January 1, 2021. As such, the Company plans to adopt ASU 2016-02 effective January 1,2021.

(6) Derivative Instruments and Hedging Activities

TheCompanyusesvariable-rateLondonInterbankOfferedRate(LIBOR)debttofinanceitsoperations.The debt obligations expose the Company to variability in interest payments due to changes in interest rates. Management believes that it is prudent to limit the variability of a portion of its interest payments. To meet this objective, management enters into LIBOR based interest rate swap agreements to manage fluctuations in cash flows resulting from changes in the benchmark interest rate of LIBOR. The swap changes the variable-rate cash flow exposure on the debt obligations to fixed cash flows. Under the terms of the interest rate swaps, the Company receives LIBOR-based variable interest rate payments and makes fixed interest rate payments, thereby creating the equivalent of fixed-rate debt for the notional amount of its debthedged.

On July 16, 2013, the Company entered into a LIBOR-based interest rate swap agreement to manage fluctuations in cash flows resulting from changes in the benchmark interest rate of LIBOR. The swap has a notionalamountof$50,000maturinginJuly2020,underthetermsofwhichtheCompanypaysafixedrate of 2.136% and receives one-month LIBOR. This swap is designated as a cash flowhedge.

On April 28, 2017 the Company entered into another swap with a notional amount of $50,000 maturing in February2022,underthetermsofwhichtheCompanypaysafixedrateof1.9365%andreceivesone-month LIBOR. This swap is designated as a cash flowhedge.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (anexitprice)intheprincipalormostadvantageousmarketfortheassetorliabilityinanorderlytransaction between market participants at the measurement date. U.S. GAAP establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level3–Unobservableinputsthataresupportedbylittleornomarketactivityandthataresignificanttothe fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies, and similar techniques that use significant unobservableinputs.

The Company’s derivatives are valued using Level 2 inputs. The fair values are disclosed in Note 6. The Company does not have any significant financial or nonfinancial assets or liabilities that are valued using Level 3 inputs.
