Armstrong World Industries (AWI) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Armstrong World Industries published the results on October 27, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Armstrong World Industries reports EPS two ways: GAAP, under the accounting rules every US filer follows, and adjusted diluted, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Architectural Specialties includes Eventscape (acquired February 2026), Parallel (December 2025) and Geometrik (September 2025). Armstrong calls their results inorganic: $8.2 million of Q3 2026 net sales.

How Armstrong World Industries splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• Armstrong World Industries's Mineral Fiber revenue was $292 million in Q3 2026, up 7% from $274 million in Q3 2025, 61% of total revenue.
• Armstrong World Industries's Architectural Specialties revenue was $184 million in Q3 2026, up 21% from $151 million in Q3 2025, 39% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

• Q3 2026 (this page), reported Oct 27, 2026

Armstrong World Industries' net sales were $475.8 million in Q3 2026, up 11.9% from $425.2 million, a record for a third quarter. Higher volumes added $35 million and favorable average unit value (AUV, Armstrong's measure of like-for-like price plus mix) added $16 million. Mineral Fiber, which makes suspended mineral fiber and fiberglass ceiling systems, had net sales of $292.1 million, and Architectural Specialties had $183.7 million. (Armstrong World Industries Q3 2026 release, Oct 27, 2026; Armstrong World Industries Form 10-K, 2025, Feb 24, 2026)

Mineral Fiber net sales rose $18 million, or 6.6%: $16 million from favorable AUV, driven by like-for-like price and to a lesser extent mix, and $2 million from volume, mainly timing-related demand from Canadian customers. Most Mineral Fiber sales go through distributors, $220.7 million in the quarter, with $29.2 million to home centers and $16.3 million to direct customers. (Armstrong World Industries Q3 2026 release, Oct 27, 2026; Armstrong World Industries Form 10-Q, Q3 2026, Oct 27, 2026)

Architectural Specialties net sales rose $33 million, or 21.5%, made up of $25 million of organic growth across most specialty product categories and an $8 million contribution from acquisitions. Armstrong bought Eventscape in February 2026 for $64.6 million, net of cash, after buying Parallel in December 2025 and Geometrik in September 2025. In this segment direct customers bought $95.0 million and distributors $82.8 million.

Armstrong's 10-K says about 63% of 2025 consolidated net sales went to building materials distributors and nearly 7% to home centers. Two of its largest distributor customers changed hands in 2025: The Home Depot acquired GMS in September 2025, and Lowe's acquired Foundation Building Materials in October 2025. (Armstrong World Industries Form 10-K, 2025, Feb 24, 2026)

Armstrong World Industries' GAAP diluted EPS rose 9.6% to $2.17 in Q3 2026, and adjusted diluted EPS rose 10.2% to $2.26. The adjusted figure excludes $5 million of acquisition-related intangible amortization, along with retirement plan (RIP) costs and acquisition fees, and applies an adjusted tax expense of $34 million. (Armstrong World Industries Q3 2026 release, Oct 27, 2026; Armstrong World Industries Q3 2026 earnings presentation, Oct 27, 2026)

Net earnings grew more slowly than operating income, 6.5% against 11.9%, because the effective tax rate rose to 26% from 21% a year earlier. Operating income of $131.2 million benefited from $13 million of margin on higher volume, $9 million from favorable AUV and $4 million more equity earnings from WAVE, the 50%-owned joint venture that makes ceiling suspension (grid) systems, offset in part by a $10 million rise in manufacturing costs from freight and raw material inflation.

Buybacks lowered the share count. Diluted shares were 42.3 million, against 43.6 million a year earlier. Armstrong repurchased 0.4 million shares in Q3 2026 for $75 million, at an average of $174.36, and had $1.1 billion left under its $2.5 billion program, which runs through December 2029. (Armstrong World Industries Q3 2026 release, Oct 27, 2026; Armstrong World Industries Q3 2026 earnings presentation, Oct 27, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Armstrong World Industries gives full-year guidance and updates it each quarter. With Q3 2026 results it set 2026 net sales at $1,788 to $1,803 million (10% to 11% growth over $1,621 million in 2025), adjusted EBITDA at $602 to $612 million, adjusted diluted EPS at $8.30 to $8.40, and adjusted free cash flow at $380 to $390 million. The prior ranges were $1,770 to $1,800 million for net sales, $605 to $620 million for adjusted EBITDA and $8.30 to $8.50 for adjusted EPS. (Armstrong World Industries Q3 2026 release, Oct 27, 2026; Armstrong World Industries Q3 2026 earnings presentation, Oct 27, 2026)

Armstrong said the update reflects stronger organic Architectural Specialties sales, accelerating cost inflation in both segments, Mineral Fiber mix headwinds and softer contributions from recent acquisitions. It now assumes Mineral Fiber sales growth of about 6.5% (prior about 7%) and Architectural Specialties growth of 18-19% (prior 15-17%), with a book tax rate of about 25% and about 42.5 million shares outstanding.

A consensus figure is the average of the models published by the analysts who cover Armstrong World Industries, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Armstrong World Industries's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning AWI is on is AWI a buy or a sell?, what analysts expect next is on the AWI forecast, and what the company does is on the Armstrong World Industries (AWI) stock page.

Every number on this page can be traced to a document Armstrong World Industries published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
