Independent Auditors’ Report

The Board of Directors

Worthington Armstrong Venture:

Opinion

We have audited the consolidated financial statements of Worthington Armstrong Venture and its subsidiary (the Company), which comprise the consolidated balance sheets as of December 31, 2023 and 2022, 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, 2023, and the related notes to the consolidated financial statements.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2023 in accordance with U.S. generally accepted accounting principles.

Basis for Opinion

We conducted our audits in accordance with auditing standards generally accepted in the United States of America (GAAS). Our responsibilities under those standards are further described in the Auditors’ Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are required to be independent of the Company and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements relating to our audits. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.
 

Responsibilities of Management for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with U.S. generally accepted accounting principles, and for 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.

In preparing the consolidated financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year after the date that the consolidated financial statements are issued.

Auditors’ Responsibilities for the Audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an audit conducted in accordance with GAAS will always detect a material misstatement when it exists. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the consolidated financial statements.

In performing an audit in accordance with GAAS, we:

We are required to communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control related matters that we identified during the audit.

See accompanying notes to consolidated financial statements.

(1) Description of Business

Worthington Armstrong Venture (the Company) is a general partnership, formed in June 1992, between Armstrong Ventures, Inc. (Armstrong), a subsidiary of Armstrong World Industries, Inc., and The Worthington Steel Company (Worthington), a Delaware corporation (a subsidiary of Worthington Enterprises, Inc.). Its business is to manufacture and market suspension systems for commercial and residential ceiling markets throughout the world. The Company has seven manufacturing plants located throughout the United States.

(2) Summary of Significant Accounting Policies

(a) Basis of Presentation and Use of Estimates

These consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and include management estimates and judgments, where appropriate. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the valuation of property, plant, and equipment and goodwill, operating lease liabilities and right-of-use assets, accrual for volume rebates, and assets and obligations related to employee benefits.

The consolidated financial statements include the accounts of the Company and its subsidiary. All significant intercompany transactions have been eliminated.

(b) Revenue Recognition

The Company recognizes revenue upon transfer of control of 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 for the products purchased under the arrangement. Direct shipments to building materials distributors, home centers, direct customers and retailers represent the majority of sales transactions. Standard sales terms are Free On Board (“FOB”) shipping point; however, the Company does have minimal sales terms that are FOB destination. At the point of shipment, the customer is required to pay under normal 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 typically short.

The Company’s products are sold with normal and customary return provisions. Limited warranties are provided 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 written instructions. In addition to the warranty program, under certain limited circumstances, the Company will occasionally, at its 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 the Company’s independent distributors. Sales returns and warranty claims have historically not been material and do not constitute separate performance obligations.

The Company often offers incentive programs to its customers, primarily volume rebates and promotions. The majority of the Company’s rebates are designated as a percentage of annual customer purchases. Rebate amounts are estimated based on actual sales for the period and accrued for the projected incentive programs costs. The costs of rebate accruals are recorded as a reduction to revenue. Other sales discounts, including early pay promotions, are deducted immediately from the sales invoice.

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 Hedging Activities

The Company recognizes all derivative instruments as either assets or liabilities in the consolidated 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 $1,844, $2,102, and $2,079 for the years ended December 31, 2023, 2022, and 2021 respectively.

(e) Research and Development Expenditures

The Company recognizes research and development expense as expenditures are incurred. Total research and development expense was $3,924, $4,195, and $4,157 for the years ended December 31, 2023, 2022, and 2021 respectively.

(f) Taxes

The Company is a general partnership in the United States, and accordingly, generally, U.S. federal and state income taxes are the responsibility of the two general partners. The Company recognizes the effect of uncertain income tax positions only if those positions are more likely than not of being sustained. Recognized income tax benefits are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

(g) Trade Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for doubtful accounts for estimated credit losses inherent in its accounts receivable portfolio. In establishing the required allowance, management considers historical losses, current receivables aging, and existing industry and national economic data. 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 its customers.

(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‑Lived Assets

Property, plant, and equipment are stated at cost, with accumulated depreciation and amortization deducted to arrive at net book value. Depreciation charges are determined generally on the straight-line basis over the useful lives as follows: buildings, 30 years; machinery and equipment, 5 to 15 years; and leasehold improvements over the shorter of 10 years or the life of the lease. Impairment losses are 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 fair value.

(j) Leases

The Company enters into operating leases for certain manufacturing plants, warehouses, and automobiles. The Company’s leases have remaining lease terms of up to 10 years. Several leases include options for the Company to renew in certain increments. The Company considers these components in determining the lease term used to establish the right-of-use ("ROU") assets and lease liabilities when it is reasonably certain that the Company will exercise that option. The Company’s lease agreements do not contain any residual value guarantees or material restrictive covenants. Short term

leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet. The lease expenses are recognized on a straight-line basis over the lease term.

As the Company’s leases do not provide an implicit rate, an Incremental Borrowing Rate (“IBR”) based on information that is available at the lease commencement date is used to compute the present value of lease payments, which is an estimate of the collateralized borrowing rate the Company would incur on future lease payments over a similar term.

(k) Goodwill

Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in a purchase business combination. Goodwill is tested for impairment at least annually. The impairment tests performed in 2023 and 2022 did not result in an impairment of goodwill.

(l) Recently Issued Accounting Standards

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 establishes a ROU model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The FASB issued additional related ASUs that provide further guidance and clarification and become effective for the Company upon the adoption of ASU 2016-02.

Effective January 1, 2022, the Company adopted these standards using the modified retrospective transition approach. The Company elected to adopt the package of transition practical expedients and, therefore, has not reassessed (1) whether existing or expired contracts contain a lease, (2) lease classification for existing or expired leases or (3) the accounting for initial direct costs that were previously capitalized. Adoption of the new leasing standard had a material effect on the Company’s consolidated balance sheet but did not materially affect the consolidated statement of income and comprehensive income. Adoption drove a $29,439 increase in operating lease liabilities with a corresponding equal increase in ROU assets as of January 1, 2022. Adoption did not have a material impact to the Company’s consolidated statement of cash flows.

In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance, which requires most business entities to disclose information about certain government assistance they receive. The related disclosure requirements include (1) the nature of the transactions and the related accounting policy used; (2) the line items on the balance sheet and income statement that are affected and the amounts applicable to each financial statement line item; and (3) significant terms and conditions of the transactions. The Company adopted the ASU on January 1, 2022. See Note 10 for discussion regarding such amounts recorded in 2022.

(3) Accounts Receivable

The Company sells its products to select, preapproved customers whose businesses are directly affected by changes in economic and market conditions. The Company considers these factors and the financial condition of each customer when establishing its allowance for losses from doubtful accounts. The allowance for doubtful accounts was $134 and $167 at December 31, 2023 and 2022, respectively.

(4) Inventory
 

(5) Derivative Instruments and Hedging Activities

The Company may use interest-rate related derivative instruments to manage its exposure related to changes in interest rates on its variable-rate debt instruments and uses commodity derivatives to manage its exposure to commodity price fluctuations. The Company does not enter into derivative instruments for any purpose other than cash flow hedging. The Company does not speculate using derivative instruments.

The Company currently uses Secured Overnight Financing Rate (SOFR) debt to finance its operations after transitioning from the variable-rate London Interbank Offered Rate (LIBOR) debt in December 2022. The Company’s mechanisms for using SOFR as the base rate remain largely the same as under LIBOR, with the exception of a small monthly basis point adjustment intended to ensure that SOFR rates effectively mirror higher LIBOR rates. 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, and thus may enter into interest rate swap agreements to manage fluctuations in cash flows resulting from changes in the benchmark interest rate. The swap changes the variable-rate cash flow exposure on the debt obligations to fixed cash flows. The Company is not currently utilizing interest rate swaps; however, management will continue to evaluate opportunities to limit variability of cash flows resulting from changes in the benchmarked interest rate.

The Company also strategically enters into certain derivative instruments to hedge exposure to changes in cash flows attributable to commodity price fluctuations associated with certain forecasted transactions, specifically the future purchases of steel and aluminum used in manufacturing the Company’s products. Changes in the fair value of steel and aluminum derivative instruments designated as hedging instruments and that effectively offset the variability of cash flows associated with anticipated purchases of steel and aluminum are reported in accumulated other comprehensive income. These amounts subsequently are reclassed into cost of goods sold when the related inventory is liquidated and affects earnings. The Company assesses hedge effectiveness both at the onset of the hedge and at regular intervals throughout the life of the derivative instrument.

The fair value of derivatives designated as hedging instruments held as of December 31, 2023 and 2022 are as follows:

The amount of gain (loss) recognized in accumulated other comprehensive income was $1,091 and ($153), respectively as of December 31, 2023 and 2022.

(6) Property, Plant, and Equipment

Depreciation and amortization expense was $4,739, $4,774 and $4,273 for the years ended December 31, 2023, 2022 and 2021, respectively.

(7) Fair Value of Financial Instruments

The Company does not hold or issue financial instruments for trading purposes.

The carrying amounts of cash and cash equivalents, accounts receivable, and accounts payable approximate their fair value due to the short-term maturity of these instruments. The carrying value and estimated fair value of debt was $326,341 and $306,420, respectively, at December 31, 2023. The carrying value and estimated fair value of debt was $334,126 and $309,094, respectively, at December 31, 2022.

The fair value of the Company’s debt is based on the amount of future cash flows discounted using rates the Company would currently be able to realize for similar instruments of comparable maturity.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction 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.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies, and similar techniques that use significant unobservable inputs.

The Company’s derivatives are valued using Level 2 inputs. The fair values are disclosed in Note 5. The Company does not have any significant financial or nonfinancial assets or liabilities that are valued using Level 3 inputs.

(8) Debt

The Company has a $250,000 revolving credit facility (Facility) with PNC Bank and other lenders. Upon its expiration in March 2021, the Facility was amended and restated. While there was no change in the amount of the Facility, the term now expires March 31, 2026. In December 2022, the Company entered into an amendment to its Revolving Credit agreement which replaced LIBOR with the SOFR as the reference rate plus a spread adjustment. The Company applied an optional expedient under Topic 848, Reference Rate Reform, that allowed it to account for the contract modification as a continuation of the existing contract without further analysis. As of December 31, 2023 and 2022 there was $177,000 and $185,000, respectively, outstanding under the Facility. The Company can borrow at rates with a range over adjusted SOFR of 1.125% to 1.75%, depending on the Company’s leverage ratio, as defined by the terms of the Facility. As of December 31, 2023 and 2022, the Company’s interest rate was 6.71% and 5.68%, respectively.

On October 19, 2018, the Company issued $50,000 of 10-year private placement notes with PGIM, Inc. (PGIM Series B Notes) that mature in October 2028. At December 31, 2023 and 2022, there was $50,000 outstanding. The PGIM Series B Notes bear interest at 4.79% that is paid on a quarterly basis.

On February 5, 2021, the Company issued $50,000 of 8-year private placement notes with PGIM, Inc. (PGIM Series D Notes) that mature in February 2029. At December 31, 2023 and 2022, there was $50,000 outstanding. The PGIM Series D Notes bear interest at 3.05% that is paid on a quarterly basis.

On January 7, 2021, the Company issued $50,000 of 10-year private placement notes with Bank of America N.A. (BoA Series C Notes) that mature in January 2031. At December 31, 2023 and 2022 there was $50,000 outstanding. The BoA Series C Notes bear interest at 2.90% that is paid bi-annually.

As of December 31, 2023 and 2022, unamortized debt issuance costs were $659 and $874, respectively. The debt agreements contain certain restrictive financial covenants, including, among others, interest coverage and leverage ratios. The Company was in compliance with its covenants during the years ended and as of December 31, 2023 and 2022.

(9) Pension Benefit Programs

The Company contributes to the Worthington Industries Deferred Profit Sharing Plan for eligible U.S. employees. Costs for this plan were $1,584, $1,297 and $1,687 for 2023, 2022 and 2021, respectively.

The Company also has a U.S. defined-benefit pension plan for eligible hourly employees that worked in its former manufacturing plant located in Malvern, Pennsylvania. This plan was curtailed in January 2004 due to the consolidation of the Company’s East Coast operations, which eliminated the expected future years of service for participants in the plan.

The following tables set forth the defined-benefit pension plan’s benefit obligations, fair value of plan assets, and funded status at December 31, 2023 and 2022:

Amounts recognized in accumulated other comprehensive loss represent unrecognized net actuarial losses.

The components of net periodic benefit cost (benefit) are as follows:

The accumulated benefit obligation for the U.S. defined-benefit pension plan was $3,706 and $4,145 at December 31, 2023 and 2022, respectively. The unrecognized net loss for the defined-benefit pension plan that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the next fiscal year is $40.

The valuations and assumptions reflect the Society of Actuaries PRI 2012 mortality table with MP-2021 generational projection scales as of December 31, 2023.

Weighted average assumptions used to determine benefit obligations for the years ended and as of December 31, 2023 and 2022 are as follows:

Pension plan assets are required to be disclosed at fair value in the consolidated financial statements. Fair value is defined in Note 7 – Fair Value of Financial Instruments.

The U.S. defined-benefit pension plan assets’ fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

The following tables set forth by level within the fair value hierarchy a summary of the plan’s assets measured at fair value on a recurring basis as of December 31, 2023 and 2022, respectively:

Following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2023 and 2022.

Cash: Consists of cash and cash equivalents. The carrying amounts of cash and cash equivalents approximate fair value due to the short‑term maturity of these instruments.

Money market funds: The money market investment consists of an institutional investor money market fund, valued at the fund’s net asset value (NAV), which is normally calculated at the close of business daily. The fund’s assets are valued as of this time for the purpose of computing the fund’s NAV.

Debt securities: Consist of investments in individual corporate bonds, municipal bonds, or government bonds. These bonds are each individually valued using a yield curve model, based on observable inputs, which may also incorporate available trade and bid/ask spread data where available.

In developing the 3.50% expected long-term rate of return assumption, the Company considered its historical returns and reviewed asset class return expectations and long-term inflation assumptions.

The primary investment objective of the defined-benefit pension plan historically was to achieve long-term growth of capital in excess of 6.50% annually, exclusive of contributions or withdrawals. Near the end of 2021, the Company’s investment objective shifted to a more conservative fixed-income approach to reduce market risk in anticipation of purchasing annuities for the remaining plan participants; accordingly, during 2022 the investment mix was shifted to a fixed-income approach targeting a mix of 65% fixed income investments and 35% cash equivalents. The Company anticipates purchasing annuities for the remaining plan participants in 2024.

Each asset class utilized by the defined-benefit pension plan has a targeted percentage. The following table shows the 2023 asset allocation target and the December 31, 2023 and 2022 position:

The Company made no contributions to the U.S. defined-benefit pension plan in 2023, 2022, and 2021. The Company does not expect to contribute to the plan in 2024.

The benefits expected to be paid in each of the next five years and in the aggregate for the five years thereafter are shown in the following table:

The expected benefits are based on the same assumptions used to measure the Company’s benefit obligation at December 31, 2023.

(10) Income Taxes

The Company is a general partnership in the United States, and accordingly, U.S. federal and state income taxes are generally the responsibility of the two general partners. Therefore, no federal income tax provision has been recorded on U.S. income.

Other taxes

In 2022, the Company recorded an Employee Retention Credit (ERC) benefit of $2,154, representing a refundable payroll tax credit for eligible wages paid to our employees in 2021 under the Coronavirus Aid, Relief, and Economic Security Act. The Company accounted for the ERC by applying the grant model. The credit was recorded as an offset to payroll tax expenses within cost of goods sold and selling, general and administrative expenses in the consolidated statements of income and comprehensive income.

(11) Leases

The Company is a lessee in several noncancellable operating leases, primarily real estate for its corporate office as well as for certain of its manufacturing facilities; substantially all of the Company’s lease expense relates to building and warehouse lease expense. Several leases include options for renewal, and contain clauses for payment of real estate taxes, insurance, and certain

operating costs. In most cases, management expects that in the normal course of business, leases will be renewed or replaced by other leases.

Minimum rent payments under operating leases are recognized on a straight-line basis over the term of the lease including any periods of free rent. Rent expense during 2023, 2022, and 2021 amounted to $5,005, $4,347, and $3,304, respectively.

Short-term lease expense and variable lease costs were not material for the years ended December 31, 2023, 2022 and 2021. As of December 31, 2023, the Company did not have any material leases that have not yet commenced.

The weighted average remaining lease term for the Company’s operating leases at December 31, 2023 and 2022 was 8.3 years and 9.4 years, respectively. The weighted average discount rate at December 31, 2023 and 2022 was 4.1% and 4.1%, respectively.

Cash paid for amounts included in the measurement of lease liabilities was $5,701 and $3,872 for the years ended December 31, 2023 and 2022, respectively.

Maturities of operating lease liabilities under noncancellable leases as of December 31, 2023 are as follows:

(12) Accumulated Other Comprehensive Income (Loss)

The following table summarizes the activity, by component, related to the change in AOCI for December 31, 2023 and the balances for accumulated other comprehensive income (loss):

The amount reclassified from AOCI was recorded in other income, net in the consolidated statements of income and comprehensive income.

(13) Related Parties

AWI provides certain selling, promotional, and administrative processing services to the Company for which it receives reimbursement. AWI purchases grid products from the Company, which are then resold along with AWI inventory to AWI's customers.

AWI owed the Company $1,913 and $5,336 for purchases of product as of December 31, 2023 and 2022, respectively, which are included in receivables from affiliates.

Worthington, and affiliates of Worthington, provide certain administrative processing services, steel processing services, and insurance‑related coverages to the Company for which it receives reimbursement.
