Armstrong World Industries, Inc. (NYSE:AWI), an Americas leader in the design and manufacture of innovative interior and exterior architectural applications including ceilings, specialty walls and exterior metal solutions, today reported fourth-quarter and full-year 2024 financial results highlighted by robust sales and earnings growth.

"These strong fourth-quarter results capped off another year of significant growth for Armstrong with record-setting sales and earnings, strong free cash flow generation, and two meaningful acquisitions to grow our Architectural Specialties capabilities," said Vic Grizzle, President and CEO of Armstrong World Industries. "These achievements are a testament to our teams' ability to execute our consistent and sustainable growth model in challenging market conditions while continuing our investments in industry-leading innovation and digital initiatives. Our proven record of success gives us confidence we can sustain our consistent growth trajectory in 2025."

^{* The Company uses non-GAAP adjusted measures in managing the business and believes the adjustments provide meaningful comparisons of operating performance between periods and are useful alternative measures of performance. Reconciliations of the most comparable generally accepted accounting principles in the United States ("GAAP") measure are found in the tables at the end of this press release. Excluding per share data, non-GAAP figures are rounded to the nearest million and corresponding percentages are rounded to the nearest decimal.}

Consolidated fourth-quarter 2024 net sales increased 17.7% due to higher sales volumes of $36 million and favorable Average Unit Value ("AUV") of $20 million. Mineral Fiber net sales increased $18 million, while Architectural Specialties net sales increased $38 million. The increase in Mineral Fiber net sales was driven by improved AUV, as a result of favorable mix and increased like-for-like pricing, partially offset by lower sales volumes. Architectural Specialties segment net sales improved primarily due to a $25 million contribution from the recent acquisitions of Zahner, 3form, LLC ("3form") and BOK Modern, LLC ("BOK"), in addition to increased custom project net sales.

Consolidated fourth-quarter 2024 operating income increased 23.5% primarily due to a $21 million margin benefit from Architectural Specialties sales volume growth, a $10 million margin benefit from AUV, and a $4 million increase in equity earnings from Worthington Armstrong Venture ("WAVE"). These benefits were partially offset by a $12 million increase in selling, general and administrative ("SG&A") expenses and a $7 million increase in manufacturing and input costs. Higher operating costs were driven primarily by the acquisition of 3form and increased employee costs, partially offset by lower acquisition-related expenses. The acquisitions of Zahner, 3form and BOK drove the 100 basis points of adjusted EBITDA margin compression in the quarter.

Mineral Fiber net sales increased 8.1% in the fourth quarter of 2024 due to $20 million of favorable AUV, partially offset by $2 million of lower sales volumes. The improvement in AUV was driven by both favorable mix and like-for-like pricing.

Mineral Fiber operating income increased by 12.6% in the fourth quarter of 2024 primarily due to a $10 million margin benefit from favorable AUV and a $5 million increase in WAVE equity earnings. These benefits were partially offset by a $5 million increase in SG&A expenses, primarily driven by higher employee costs as well as a decrease in company-owned officer life insurance gains related to deferred compensation plans, and a $2 million increase in manufacturing and input costs.

Architectural Specialties net sales increased 40.8% in the fourth quarter of 2024 driven primarily by a $25 million increase due to the acquisitions of Zahner, 3form and BOK, and partially due to improved custom project net sales.

Architectural Specialties operating income increased by $8 million in the fourth quarter of 2024 primarily due to a $22 million margin benefit from higher sales volumes, partially offset by a $5 million increase in manufacturing costs. In addition, SG&A expenses increased by $8 million in the fourth quarter of 2024, primarily driven by an $11 million increase related to the acquisitions of Zahner, 3form and BOK and a $2 million increase in selling expenses to support sales growth, partially offset by a $6 million decrease in acquisition-related expenses.

Consolidated net sales for 2024 increased 11.6% due to higher sales volumes of $89 million and favorable AUV of $62 million. Mineral Fiber net sales increased $54 million, while Architectural Specialties net sales increased $97 million. The increase in Mineral Fiber net sales was primarily driven by improved AUV, as a result of increased like-for-like pricing and favorable mix, partially offset by lower sales volumes. The decrease in volumes for 2024 was driven primarily within our home center customer channel, most notably due to prior-year first quarter inventory level increases that did not repeat in the current-year period, partially offset by two additional shipping days in 2024 and the positive contribution from our growth initiatives compared to the prior-year period. Architectural Specialties net sales improved primarily due to a $73 million contribution from the acquisitions of Zahner, 3form and BOK, in addition to increased custom project net sales.

Consolidated operating income increased 15.6% primarily due to a $53 million margin benefit from higher sales volumes, a $39 million benefit from favorable AUV and a $14 million increase in equity earnings from unconsolidated affiliates. These increases were partially offset by a $46 million increase in SG&A expenses and a $7 million increase in manufacturing and input costs, primarily driven by higher costs from the acquisitions of Zahner, 3form and BOK, partially offset by improved Mineral Fiber manufacturing productivity.

The year-over-year increase in SG&A expenses was primarily driven by a $32 million increase related to the acquisitions of Zahner, 3form and BOK, an $8 million increase in selling expenses, primarily due to higher employee costs, a $7 million increase in incentive compensation and a $6 million decrease in company-owned officer life insurance gains related to deferred compensation plans. These increases were partially offset by a $9 million decrease in acquisition-related expenses.

Cash Flow

Cash flows from operating activities in 2024 increased $33 million in comparison to prior year. The favorable change in operating cash flows was primarily driven by higher cash earnings, partially offset by unfavorable net working capital impacts. Cash flows used for investing activities increased $69 million versus the prior year primarily due to $124 million of cash paid for the Zahner and 3form acquisitions, partially offset by proceeds received from sales of real estate.

Share Repurchase Program

In the fourth quarter of 2024, we repurchased 0.1 million shares of common stock for a total cost of $15 million, excluding the cost of commissions and taxes. For the full year 2024, we repurchased 0.5 million shares of common stock for a total cost of $55 million, excluding the cost of commissions and taxes. As of December 31, 2024, there was $662 million remaining under our Board of Directors' current authorized share repurchase program**.

^{** In July 2016, our Board of Directors approved a share repurchase program authorizing us to repurchase up to $150 million of our outstanding common stock through July 2018 (the "Program"). Pursuant to additional authorizations and extensions of the Program approved by our Board of Directors, including $500 million authorized on July 18, 2023, we are authorized to purchase up to $1,700 million of our outstanding shares of common stock through December 2026. Since inception and through December 31, 2024, we have repurchased 14.6 million shares under the Program for a total cost of $1,038 million, excluding commissions and taxes.}

2025 Outlook

"We delivered strong results across both segments in 2024, demonstrating the resilience of our growth model, despite challenging market conditions," said Chris Calzaretta, AWI Senior Vice President and CFO. "Turning to 2025, our focus remains on delivering profitable growth and navigating a choppy operating environment to drive margin expansion in both our Mineral Fiber and Architectural Specialties businesses. We remain focused on adjusted free cash flow growth, which will continue to fuel our balanced approach to capital deployment for value creation."

Reported Financial Results

(Amounts in millions, except per share data)

Supplemental Reconciliations of GAAP to non-GAAP Results (unaudited)

(Amounts in millions, except per share data)

To supplement its consolidated financial statements presented in accordance with accounting principles generally accepted in the United States ("GAAP"), the Company provides additional measures of performance adjusted to exclude the impact of certain discrete expenses and income including adjusted Earnings Before Interest, Taxes, Depreciation and Amortization ("EBITDA"), adjusted diluted earnings per share ("EPS") and adjusted free cash flow. Investors should not consider non-GAAP measures as a substitute for GAAP measures. The Company excludes certain acquisition related expenses (i.e. – impact of adjustments related to the fair value of inventory, contingent third-party professional fees, changes in the fair value of contingent consideration and deferred compensation accruals for acquisitions). Acquisition related deferred compensation accruals excluded from adjusted EBITDA represented cash and stock awards that were recorded over each award's respective vesting period, as such payments were subject to the sellers' and employees' continued employment with the Company. The Company also excludes all acquisition-related intangible amortization from adjusted net earnings and in calculations of adjusted diluted EPS. Examples of other excluded items have included plant closures, restructuring charges and related costs, impairments, separation costs and other cost reduction initiatives, environmental site expenses and environmental insurance recoveries, endowment level charitable contributions, the impact of defined benefit plan settlements, gains and losses on sales or impairment of fixed assets, and certain other gains and losses. The Company also excludes income/expense from its U.S. Retirement Income Plan ("RIP") in the non-GAAP results as it represents the actuarial net periodic benefit credit/cost recorded. For all periods presented, the Company was not required and did not make cash contributions to the RIP based on guidelines established by the Pension Benefit Guaranty Corporation, nor does the Company expect to make cash contributions to the plan in 2025. Adjusted free cash flow is defined as cash from operating and investing activities, adjusted to remove the impact of cash used or proceeds received for acquisitions and divestitures, environmental site expenses and environmental insurance recoveries. Management's adjusted free cash flow measure includes returns of investment from WAVE and cash proceeds received from the settlement of company-owned life insurance policies, which are presented within investing activities on our consolidated statement of cash flows. The Company uses these adjusted performance measures in managing the business, including communications with its Board of Directors and employees, and believes that they provide users of this financial information with meaningful comparisons of operating performance between current results and results in prior periods. The Company believes that these non-GAAP financial measures are appropriate to enhance understanding of its past performance, as well as prospects for its future performance. The Company also uses adjusted EBITDA and adjusted free cash flow (with further adjustments, when necessary) as factors in determining at-risk compensation for senior management. These non-GAAP measures may not be defined and calculated the same as similar measures used by other companies. Non-GAAP financial measures utilized by the Company may not be comparable to non-GAAP financial measures used by other companies. A reconciliation of these adjustments to the most directly comparable GAAP measures is included in this release and on the Company's website. These non-GAAP measures should not be considered in isolation or as a substitute for the most comparable GAAP measures.
