Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

November 2026 Investor Presentation Exhibit 99.2
Safe Harbor Statement When we refer to “AWI,” the “Company,” “we,” “our” or “us,” we are referring to Armstrong World Industries, Inc. and its subsidiaries. Certain statements in this presentation may constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Those forward-looking statements are subject to various risks and uncertainties and include all statements that are not historical statements of fact and those regarding our intent, belief or expectations, including, but not limited to, our expectations concerning our markets and demand for our products, tariffs, broader economic conditions and their effect on our operating results; our expectations regarding the payment of dividends and stock repurchases; and our ability to increase revenues, earnings and earnings before interest, taxes, depreciation and amortization. Words such as “anticipate,” “estimate,” “expect,” “project,” “position,” “deliver,” “intend,” “plan,” “believe,” “outlook,” “target,” “predict,” “mitigate,” “may,” “will,” “would,” “could,” “should,” “seek,” and similar expressions are intended to identify such forward-looking statements. These statements are based on management’s current expectations and beliefs and are subject to a number of factors that could lead to actual results materially different from those described in the forward-looking statements. Although we believe that the assumptions underlying the forward-looking statements are reasonable, we can give no assurance that our expectations will be attained. A more detailed discussion of the risks and uncertainties that could cause our actual results to differ materially from those projected, anticipated or implied is included in the “Risk Factors” and “Management’s Discussion and Analysis” sections of our reports on Form 10-K and Form 10-Q filed with the U.S. Securities and Exchange Commission (“SEC”), including our quarterly report for the quarterly period ended September 30, 2026. Forward-looking statements speak only as of the date they are made. We undertake no obligation to update any forward-looking statements beyond what is required under applicable securities law. In addition, this presentation includes references to non-Generally Accepted Accounting Principles in the United States (“GAAP”) financial measures within the meaning of SEC Regulation G. A reconciliation of the differences between these measures with the most directly comparable financial measures calculated in accordance with GAAP is included within this presentation and available on the Investor Relations page of our website at www.armstrong.com. The full year guidance in this presentation is effective only as of the date it was given, October 27, 2026, and will not be updated or affirmed unless and until we publicly announce updated or affirmed guidance.
Basis of Presentation Explanation Results throughout this presentation are presented on a normalized basis. We remove the impact of certain discrete expenses and income in certain measures including adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”), adjusted diluted earnings per share (“EPS”) and adjusted free cash flow. 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, 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 to 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 the Worthington Armstrong Venture (“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. Investors should not consider non-GAAP measures as a substitute for GAAP measures. Excluding adjusted diluted EPS, non-GAAP figures are rounded to the nearest million and corresponding percentages are rounded to the nearest decimal based on unrounded figures. Basis point changes are calculated based on unrounded margin percentages and rounded to the nearest ten basis points. Operating Segments: “MF”: Mineral Fiber, “AS”: Architectural Specialties, “UC”: Unallocated Corporate. We define “organic” as total company and/or AS results excluding the impact of the February 2026 acquisition of Event Scape Inc. and Eventscape U.S. Holdings Inc. (collectively, “Eventscape”), the December 2025 acquisition of FGM-Parallel LLC (“Parallel”) and the September 2025 acquisition of Geometrik Manufacturing, Inc. (“Geometrik”). All dollar figures throughout the presentation are in $ millions, expect per share data, and all comparisons are versus prior year unless otherwise noted. Figures may not sum due to rounding.
