Record-setting first-quarter Net Sales with double-digit growth in Architectural Specialties and solid Mineral Fiber results driven by both Average Unit Value (AUV) and volume growth
Operating Income down 4% and Adjusted EBITDA up 1%
Diluted Net Earnings Per Share down 2% and Adjusted Diluted Net Earnings Per Share up 2%
Reaffirming 2026 guidance for Net Sales, Adjusted EBITDA and Adjusted Free Cash Flow; Raising Adjusted Diluted Earnings Per Share guidance to +10% to +14% growth versus prior year

(Comparisons above are versus the prior-year period unless otherwise stated)

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 first-quarter 2026 financial results highlighted by 7.1% net sales growth.

"We delivered solid topline growth this quarter, driven by Mineral Fiber AUV and higher volumes, along with double-digit sales growth in Architectural Specialties," said AWI President and CEO, Mark Hershey. "We continued to deliver strong Mineral Fiber Adjusted EBITDA performance, while total company Adjusted EBITDA in the quarter was pressured by short-term headwinds in the Architectural Specialties segment, including a non-recurring tariff adjustment, as well as continued growth investments."

"Looking forward, we remain encouraged by the stability of our key markets and our expanding order intake levels for Architectural Specialties. We are also pleased by the momentum building for our recently introduced products focused on energy efficiency and data centers. With our dedicated teams focused on execution and attractive growth initiatives, we remain confident in our expectation to deliver profitable topline growth and expanded adjusted EBITDA margins in both segments for the full year."

First-Quarter Consolidated Results

(Dollar amounts in millions except per-share data)	For the Three Months Ended March 31,
	2026			2025			Change
Net sales	$	409.9		$	382.7		7.1%
Operating income	$	94.2		$	98.5		(4.4)%
Operating income margin (Operating income as a % of net sales)		23.0	%		25.7	%	(270)bps
Net earnings	$	66.8		$	69.1		(3.3)%
Diluted net earnings per share	$	1.55		$	1.58		(1.9)%

*Additional Non-GAAP Measures**

Adjusted EBITDA margin (Adjusted EBITDA as a % of net sales)		31.7	%		33.6	%	(190)bps
Adjusted net earnings	$	73		$	73		0.5%
Adjusted diluted net earnings per share	$	1.69		$	1.66		1.8%

* 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 first quarter of 2026 increased 7.1% from the prior-year period due to higher volumes of $17 million and favorable AUV of $10 million. Architectural Specialties net sales increased $15 million and Mineral Fiber net sales increased $12 million from the prior-year period. Architectural Specialties segment net sales improved due to a $10 million increase in organic net sales and a $5 million inorganic contribution. The increase in Mineral Fiber net sales was primarily driven by favorable AUV and improved sales volumes.

Consolidated operating income decreased 4.4% in the first quarter of 2026 compared to the prior-year period, primarily driven by certain non-recurring costs and discrete items, including a $3 million increase in expenses related to severance and cost reduction actions, a $3 million increase in acquisition costs associated with the Eventscape transaction and a $2 million increase in expenses related to a tariff adjustment. Excluding the impact of these non-recurring costs and discrete items, operating income increased compared to the prior year, driven by a $9 million increase in AUV and a $7 million increase in organic sales volumes, partially offset by an $8 million organic increase in manufacturing costs and a $5 million increase in organic selling, general and administrative ("SG&A") expenses.

First-Quarter Segment Results

Mineral Fiber

(Dollar amounts in millions)	For the Three Months Ended March 31,
	2026			2025			Change
Net sales	$	257.2		$	245.1		4.9%
Operating income	$	85.5		$	84.5		1.2%
Adjusted EBITDA*	$	109		$	105		3.5%
Operating income margin		33.2	%		34.5	%	(130)bps
Adjusted EBITDA margin*		42.4	%		43.0	%	(60)bps

Mineral Fiber net sales increased 4.9% in the first quarter of 2026 compared to the prior-year quarter due to $10 million of favorable AUV, driven primarily by favorable like-for-like price, and $2 million of higher sales volumes driven primarily by solid commercial execution.

Mineral Fiber operating income increased 1.2% year-over-year due to a $9 million benefit from favorable AUV, a $1 million benefit from higher sales volumes and a $1 million increase in WAVE equity earnings. These benefits were partially offset by a $5 million increase in manufacturing costs, including raw material and energy inflation and unfavorable inventory valuation impacts, partially offset by improved manufacturing productivity, and a $4 million increase in SG&A expenses. The year-over-year increase in SG&A expenses was primarily driven by a $2 million increase related to severance and cost reduction actions and a $1 million decrease in company-owned life insurance gains related to deferred compensation plans.

Architectural Specialties

(Dollar amounts in millions)	For the Three Months Ended March 31,
	2026			2025			Change
Net sales	$	152.7		$	137.6		11.0%
Operating income	$	9.3		$	14.8		(37.2)%
Adjusted EBITDA*	$	21		$	24		(11.9)%
Operating income margin		6.1	%		10.8	%	(470)bps
Adjusted EBITDA margin*		13.6	%		17.1	%	(350)bps

Architectural Specialties net sales increased 11.0% in the first quarter of 2026 compared to the prior-year quarter due to a $10 million increase in organic net sales driven by growth within our metal and wood categories and a $5 million inorganic contribution from our 2026 and 2025 acquisitions.

Architectural Specialties operating income decreased 37.2% in the first quarter of 2026 compared to the prior-year quarter, as certain non-recurring costs and discrete items offset a $6 million benefit from higher organic net sales. These costs included a $3 million increase in acquisition costs associated with the Eventscape transaction, a $2 million increase in expenses related to a tariff adjustment and a $1 million increase in expenses related to severance and cost reduction actions. Operating income was also impacted by a $3 million increase in organic manufacturing costs and a $2 million increase in organic selling expenses, driven primarily by higher net sales and investments in selling resources to support growth, both of which pressured operating leverage.

Unallocated Corporate

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

Cash Flow

Cash flows from operating activities in the first quarter of 2026 decreased $9 million in comparison to the prior-year period. The unfavorable change in operating cash flows was primarily driven by an unfavorable timing-related change in accounts receivable, partially offset by a favorable timing-related change in accounts payable and accrued expenses. Also contributing to the decrease in operating cash flows was an unfavorable change in net income taxes payable. Cash flows used for investing activities increased $57 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 first quarter of 2026, we repurchased 0.3 million shares of common stock for a total cost of $60 million, excluding the cost of commissions and taxes, or at an average price of $176.00 per share. As of March 31, 2026, there was $473 million remaining under our Board of Directors' current authorized share repurchase program**.

** In July 2016, our Board of Directors approved our share repurchase program authorizing us to repurchase outstanding shares of common stock (the "Program"). Since inception of the Program, this authorization has been increased to permit repurchases of up to an aggregate of $1,700 million of our outstanding shares of common stock through December 2026. Since inception and through March 31, 2026, we have repurchased 15.7 million shares under the Program for a total cost of $1,227 million, excluding commissions and taxes, or an average of $77.89 per share.

Maintaining 2026 Outlook

"While first quarter topline results were solid in both segments, we faced margin pressure in Architectural Specialties primarily due to short-term headwinds in the quarter," said Chris Calzaretta, AWI Senior Vice President and CFO. "Looking ahead, we expect profitability to improve sequentially and further accelerate in the second half of the year as we continue to execute our value creation drivers across the company. We remain confident in our outlook for the year and expect full-year margin expansion in both segments. We are also reaffirming our full-year Net Sales, Adjusted EBITDA and Adjusted Free Cash Flow guidance and are modestly increasing our Adjusted Diluted Net Earnings Per Share guidance to reflect acceleration in our share repurchases as we continue to deliver 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.
