Armstrong World Industries, Inc. (NYSE:AWI), a leader in the design, innovation and manufacture of ceiling and wall solutions in the Americas, today reported third-quarter 2024 financial results highlighted by robust sales and earnings growth.

“With another quarter of record setting sales and strong earnings growth, we continue to demonstrate our ability to deliver growth despite muted market conditions through operational execution and our investments in strategic acquisitions, innovation and digital initiatives,” said Vic Grizzle, President and CEO of Armstrong World Industries. “As market demand continues to stabilize, we are well positioned to deliver full year double-digit top and bottom-line growth with industry-leading margin performance through strong Mineral Fiber Average Unit Value improvement, market-driven innovation, operational excellence and Architectural Specialties growth.”

Third-quarter 2024 consolidated net sales increased 11.3% from prior-year results, driven by higher volumes of $30 million and favorable Average Unit Value (dollars per unit sold, or "AUV") of $9 million. Architectural Specialties net sales increased $31 million and Mineral Fiber net sales increased $8 million. Architectural Specialties segment net sales improved primarily due to a $25 million increase from our April 2024 acquisition of 3form, LLC ("3form") and our July 2023 acquisition of BOK Modern, LLC ("BOK"). The increase in Mineral Fiber net sales was primarily driven by favorable AUV.

Consolidated operating income increased 11.1% in the third quarter of 2024 primarily due to a $17 million margin benefit from higher sales volumes, a $6 million benefit from favorable AUV and a $2 million increase in Worthington Armstrong Joint Venture ("WAVE") equity earnings. These benefits were partially offset by a $13 million increase in selling, general and administrative (“SG&A”) expenses, primarily due to the impact of acquisitions, and to a lesser extent, an increase in Mineral Fiber SG&A expenses.

Mineral Fiber net sales increased 3.3% in the third quarter of 2024 due to $10 million of favorable AUV, partially offset by $1 million of lower sales volumes. The improvement in AUV was driven by favorable like-for-like pricing.

Mineral Fiber operating income increased in the third quarter of 2024 primarily due to a $6 million benefit from favorable AUV, a $3 million decrease in manufacturing and input costs and a $2 million increase in WAVE equity earnings primarily driven by favorable AUV. These benefits were partially offset by a $3 million increase in SG&A expenses, primarily driven by higher incentive compensation.

Architectural Specialties net sales increased 31.8% in the third quarter of 2024 driven primarily by a $25 million increase due to the acquisitions of 3form and BOK, in addition to increased custom metal project net sales.

Architectural Specialties operating income increased in the third quarter of 2024 primarily due to an $18 million margin benefit from increased sales, driven primarily by the acquisitions of 3form and BOK, and partially due to improved custom project margins. This increase largely offset a $10 million increase in SG&A expenses and a $4 million increase in manufacturing costs, both of which were primarily due to the acquisitions of 3form and BOK.

Unallocated Corporate

Unallocated Corporate operating loss was $1 million in the third quarter of 2024 and 2023.

Cash Flow

Year-to-date cash flows from operating activities in 2024 increased $4 million in comparison to the prior-year period. The favorable change in operating cash flows was primarily driven by higher cash earnings partially offset by net unfavorable working capital impacts. Year-to-date cash flows from investing activities decreased $51 million versus the prior-year period primarily due to $94 million of cash paid for the acquisition of 3form, partially offset by proceeds received from sales of real estate.

Share Repurchase Program

During the third 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. As of September 30, 2024, there was $677 million remaining under our Board of Directors' current authorized share repurchase program**.

Updating 2024 Outlook

“We delivered strong profitability in the third quarter, highlighted by forty-four percent Mineral Fiber and twenty percent Architectural Specialties adjusted EBITDA margins. With our strong third quarter results and an improved profitability outlook for the remainder of the year, we are increasing our full-year 2024 guidance for adjusted EBITDA and adjusted diluted net earnings per share, as well as modestly increasing guidance for adjusted free cash flow, while tightening the range on our full-year sales outlook,” said Chris Calzaretta, AWI Senior Vice President and CFO. “We remain focused on expanding adjusted EBITDA margin at the total company level and expect to deliver a fourth consecutive year of net sales and earnings growth in 2024. With a strong balance sheet and our demonstrated ability to generate cash, we expect to continue to execute our capital allocation strategy to drive shareholder value.”

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 2024. 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 condensed 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.

In the following charts, numbers may not sum due to rounding. Excluding adjusted diluted EPS, non-GAAP figures are rounded to the nearest million and corresponding percentages are rounded to the nearest percent based on unrounded figures.
