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 second-quarter 2026 financial results highlighted by double-digit net sales and solid earnings growth.

"Consistent execution across our enterprise and continued contributions from our growth initiatives drove record quarterly net sales, operating income and adjusted EBITDA, with solid performance in both segments," said AWI President and CEO, Mark Hershey. "Mineral Fiber delivered solid Average Unit Value growth and a second consecutive quarter of volume growth, while Architectural Specialties posted double-digit sales growth and a healthy adjusted EBITDA margin. These results reflect the durability of our business model, the strength of our growth initiatives and the dedication, discipline and customer focus of our teams. While we continue to monitor macroeconomic and geopolitical uncertainty, we remain well-positioned to manage through these conditions, execute on our growth initiatives and capture additional market opportunities as they emerge."

* 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 net sales for the second quarter of 2026 increased 11.2% from the prior-year quarter due to higher volumes of $31 million and favorable AUV of $16 million. Architectural Specialties net sales increased $26 million and Mineral Fiber net sales increased $21 million from the prior-year quarter. Architectural Specialties segment net sales improved due to a $15 million increase in organic net sales and an $11 million inorganic contribution from the 2025 and 2026 acquisitions. The increase in Mineral Fiber net sales was driven by favorable AUV and improved sales volumes.

Consolidated operating income increased 8.6% in the second quarter of 2026 compared to the prior-year period, primarily due to a $13 million margin benefit from sales volume growth, a $12 million margin benefit from favorable AUV and a $2 million increase in equity earnings from the Worthington Armstrong Joint Venture ("WAVE"). These benefits were partially offset by a $9 million increase in selling, general and administrative ("SG&A") expenses and a $6 million increase in manufacturing costs. Manufacturing costs included a $2 million benefit from tariffs, driven by International Emergency Economic Powers Act ("IEEPA") tariff refunds recognized during the quarter.

Second-Quarter Segment Results

Mineral Fiber

(Dollar amounts in millions)	For the Three Months Ended June 30,
	2026			2025			Change
Net sales	$	288.2		$	267.0		7.9%
Operating income	$	105.3		$	98.4		7.0%
Adjusted EBITDA*	$	129		$	121		6.8%
Operating income margin		36.5	%		36.9	%	(40)bps
Adjusted EBITDA margin*		44.7	%		45.2	%	(50)bps

Mineral Fiber net sales increased $21 million in the second quarter of 2026 compared to the prior-year quarter primarily due to $16 million of favorable AUV, including both favorable like-for-like price and mix driven by continued demand at the high-end of the product portfolio. Additionally, net sales benefited from $5 million of higher volumes, driven primarily by strong commercial execution and benefits from growth initiatives.

Mineral Fiber operating income increased 7.0% due to a $12 million margin benefit from favorable AUV, a $3 million margin benefit from higher sales volumes and a $2 million increase in WAVE equity earnings. These benefits, along with manufacturing productivity gains, were partially offset by a $5 million increase in SG&A expenses, primarily driven by investments to support growth, and a $4 million increase in manufacturing costs, including freight, raw material and energy inflation.

Architectural Specialties

(Dollar amounts in millions)	For the Three Months Ended June 30,
	2026			2025			Change
Net sales	$	183.8		$	157.6		16.6%
Operating income	$	29.4		$	25.6		14.8%
Adjusted EBITDA*	$	37		$	34		10.4%
Operating income margin		16.0	%		16.2	%	(20)bps
Adjusted EBITDA margin*		20.4	%		21.5	%	(110)bps

Architectural Specialties net sales increased $26 million in the second quarter of 2026 compared to the prior-year quarter due to a $15 million increase in organic net sales driven by strong growth across most specialty product categories and an $11 million inorganic contribution.

Architectural Specialties operating income increased 14.8% due to a $5 million margin benefit from higher organic net sales, which includes the impact of higher steel and aluminum costs, and a $4 million inorganic contribution. These benefits were partially offset by a $4 million increase in SG&A expenses, of which approximately half were driven by the 2026 and 2025 acquisitions. In addition, manufacturing costs increased $1 million, inclusive of a $2 million benefit from IEEPA tariff refunds.

Unallocated Corporate

Unallocated Corporate operating loss was $1 million in the second quarter of 2026 and 2025.

Cash Flow

Year-to-date cash flows from operating activities in 2026 increased $3 million or 3% in comparison to the prior-year period. The favorable change in operating cash flows was primarily driven by an increase in cash earnings and favorable timing related changes in accounts payable and accrued expenses, partially offset by unfavorable timing related changes in receivables. Year-to-date cash flows used for investing activities increased $58 million in comparison to the prior-year period, primarily due to cash paid for the acquisition of Eventscape, partially offset by an increase in dividends from WAVE.

Share Repurchase Program

In the second quarter of 2026, the Company repurchased 0.5 million shares of common stock for a total cost of $75 million, excluding the cost of commissions and taxes, at an average price of $163.20 per share. As of June 30, 2026, there was $398 million remaining under the existing authorized share repurchase program. On July 21, 2026, the Board of Directors of the Company authorized an additional $800 million to be added to the Company's existing share repurchase program authorization and extended the authorization through December 2029**.

** In July 2016, the Board of Directors of the Company approved a share repurchase program authorizing the repurchase of outstanding shares of common stock (the "Program"). Pursuant to additional authorization and extensions of the Program approved by the Board of Directors, including $800 million authorized on July 21, 2026, the Company is authorized to repurchase up to $2.5 billion of outstanding shares of common stock through December 2029. Since inception and through June 30, 2026, the Company has repurchased 16.2 million shares under the Program for a total cost of $1.3 billion, excluding commissions and taxes, or an average of $80.31 per share.

Updating 2026 Outlook

"We are pleased with our second quarter results, delivering double-digit sales growth for the total company and solid profitability across both segments against a strong prior-year comparison," said Chris Calzaretta, AWI Senior Vice President and CFO. "The strength of that performance gives us the confidence to raise the midpoint of our full-year guidance across all key metrics. As we look to the second half of the year, we remain focused on executing our growth strategy, driving operational excellence, and continuing to create value for our shareholders."

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, third-party professional fees and changes in the fair value of contingent consideration for acquisitions). 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, 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 2026. 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.
