LANCASTER, Pa.--(BUSINESS WIRE)--Feb. 24, 2026-- 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 2025 financial results highlighted by strong sales and earnings growth and issued 2026 guidance with strong growth across all key metrics.

“These results represent another strong year for Armstrong with record-setting sales and earnings for both the quarter and the full year as the key fundamental growth drivers of our business – Mineral Fiber average unit value growth, productivity and Architectural Specialties sales growth – were on full display,” said Vic Grizzle, President and CEO of Armstrong World Industries. “For the second consecutive year, we have achieved double-digit growth in both annual sales and earnings, and for the fifth consecutive year we have delivered profitable top and bottom line growth despite challenging market conditions. This sustained profitable growth reflects the impact from successful investments in our growth initiatives, the dedication and agility of our teams, our commitment to operational excellence, and the strength of our resilient business model. Together with our disciplined strategy to strengthen our core business and expand into adjacencies, the resulting consistent cash flow generation allows for reinvestment for profitable growth. It’s these attributes that set Armstrong apart and provide a strong foundation as we transition to our next CEO, Mark Hershey, and position us for continued growth into 2026 and beyond.”

Fourth-Quarter Consolidated Results

Consolidated net sales for the fourth quarter of 2025 increased 5.6% from the prior-year period due to higher volumes of $6 million and favorable Average Unit Value ("AUV") of $15 million. Architectural Specialties net sales increased $14 million and Mineral Fiber net sales increased $6 million from the prior-year period. Architectural Specialties net sales improved primarily due to an $8 million contribution from the 2024 acquisitions of 3form, LLC and A. Zahner Company (collectively "the 2024 Acquisitions") and a $5 million increase in organic net sales. The increase in Mineral Fiber net sales was driven by favorable AUV, partially offset by lower sales volumes.

Consolidated operating income increased 12.3% in the fourth quarter of 2025 compared to the prior-year period primarily due to a $13 million margin benefit from favorable AUV and a $1 million increase in equity earnings from the Worthington Armstrong Joint Venture ("WAVE"). These benefits were partially offset by a $2 million increase in selling, general and administrative ("SG&A") expenses, driven primarily by the 2024 Acquisitions, and a $2 million increase in manufacturing costs.

Fourth-Quarter Segment Results
Mineral Fiber

Mineral Fiber net sales increased 2.7% in the fourth quarter of 2025 compared to the prior-year quarter due to $15 million of favorable AUV, partially offset by $8 million of lower sales volumes. The improvement in AUV was driven by favorable like-for-like price and, to a lesser extent, favorable mix. Sales volumes decreased as benefits from our growth initiatives were more than offset by short-term headwinds from the indirect impacts of the federal government shutdown and softer home center demand.

Mineral Fiber operating income increased 17.2% year-over-year primarily due to a $13 million benefit from favorable AUV and a $2 million decrease in manufacturing costs, primarily due to favorable inventory valuation impacts and improved manufacturing productivity, partially offset by higher input costs. Also contributing to the increase in operating income was a $1 million increase in WAVE equity earnings and a $1 million reduction in SG&A expenses. These benefits were partially offset by a $6 million negative impact from lower sales volumes.

Architectural Specialties

Architectural Specialties net sales increased 11.0% in the fourth quarter of 2025 primarily due to an $8 million increase from the 2024 Acquisitions, in addition to increased organic net sales driven by growth across most of our specialty product categories.

Architectural Specialties operating income decreased $2 million in the fourth quarter of 2025, primarily due to a $4 million increase in SG&A expenses, primarily driven by the 2024 Acquisitions, and a $4 million increase in manufacturing costs primarily driven by less favorable operating leverage due to the timing of custom projects and the 2024 Acquisitions. These negative impacts were partially offset by a $5 million margin benefit from higher sales volumes.

Full-Year Consolidated Results

Consolidated net sales for 2025 increased 12.1% versus the prior year due to higher volumes of $117 million and favorable AUV of $58 million. Architectural Specialties net sales increased $130 million and Mineral Fiber net sales increased $45 million. Architectural Specialties segment net sales improved primarily due to a $94 million year-over-year increase attributable to the 2024 Acquisitions, in addition to a $36 million increase in organic net sales driven by strong growth across most of our specialty product categories. The increase in Mineral Fiber net sales was driven by favorable AUV, due to favorable like-for-like price and, to a lesser extent, favorable mix, partially offset by lower sales volumes. Our strong execution and benefits from growth initiatives contributed both volume and mix benefits, which were partially offset by a decrease in volumes driven by softer demand, primarily from home centers.

Consolidated operating income increased 15.1% primarily due to a $55 million margin benefit from higher sales volumes, a $38 million benefit from favorable AUV and a $9 million increase in WAVE equity earnings. These increases were partially offset by a $31 million increase in SG&A expenses and a $17 million increase in manufacturing costs.

The year-over-year increase in manufacturing costs was primarily driven by increased costs within Architectural Specialties, both organically and from the 2024 Acquisitions, as well as higher input costs, partially offset by improved manufacturing productivity and favorable inventory valuations within Mineral Fiber.

The year-over-year increase in SG&A expenses was primarily driven by a $27 million increase related to the 2024 Acquisitions, a $4 million increase in incentive compensation and a $3 million increase in Architectural Specialties selling and advertising expenses driven primarily by higher net sales as well as additional investments in selling capabilities. These increases were partially offset by a $2 million increase in company-owned officer life insurance gains related to deferred compensation plans and a prior-period increase in reserves for environmental remediation matters of $2 million that did not recur in the current period.

Cash Flow
Cash flows from operating activities in 2025 increased $89 million or 33% in comparison to prior year. The favorable change in operating cash flows was primarily driven by higher cash earnings compared to the prior year, including a benefit from a decrease in income taxes paid due to the impact of 2025 federal tax reform. Also contributing to the increase in operating cash flows was a favorable timing-related working capital change in accounts receivable, partially offset by an unfavorable change in inventory. Cash flows used for investing activities decreased $76 million versus the prior year, primarily due to a $110 million reduction in cash paid for acquisitions and an increase in dividends from WAVE. These decreases were partially offset by an increase in purchases of property, plant and equipment and a decrease in proceeds from the sale of fixed assets, due primarily to 2024 cash proceeds received from the sale of our idled St. Helens manufacturing plant and undeveloped land adjacent to our corporate headquarters.

Eventscape Acquisition
On February 19, 2026, we acquired Eventscape, Inc., a globally recognized design and fabrication company known for delivering complex, design-driven architectural spaces. Based in New York City and Toronto, Canada, Eventscape specializes in the design, fabrication and installation of high-design, complex architectural features for multiple applications including ceilings, feature walls and facades. With this addition as well as the 2025 acquisitions of wood ceiling product manufacturer Geometrik Manufacturing, Inc. and exterior metal manufacturer FGM-Parallel LLC, the company has completed 15 acquisitions since 2017 as part of its strategy to expand its reach and capabilities in the Architectural Specialties market in North America.

Share Repurchase Program
In the fourth quarter of 2025, we repurchased 0.3 million shares of common stock for a total cost of $50 million, excluding the cost of commissions and taxes. For the full year 2025, we repurchased 0.8 million shares of common stock for a total cost of $129 million, excluding the cost of commissions and taxes, or at an average price of $167.75 per share. As of December 31, 2025, there was $533 million remaining under our Board of Directors' current authorized share repurchase program**.

2026 Outlook
“We delivered strong results across both segments in 2025, featuring double‑digit growth across our key financial metrics and margin expansion achieved through AUV growth, continued manufacturing productivity and disciplined cost control,” said Chris Calzaretta, AWI Senior Vice President and CFO. “These results highlight the strength of our value creation drivers and the resilience of our business model that enable us to outperform in challenging market conditions. In 2026, we remain focused on delivering another year of profitable growth with further margin expansion and adjusted free cash flow growth to support all of our capital allocation priorities. With a strong balance sheet, a focus on executing our growth initiatives and a disciplined approach to capital deployment, we are confident in our ability to continue to create value for our shareholders.”

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 and percentages)

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). 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 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.
