3rd Quarter 2024 Earnings Presentation October 29, 2024 Exhibit 99.2

Safe Harbor Statement Disclosures in this presentation contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including without limitation, those relating to future financial and operational results, market and broader economic conditions and guidance. Those statements provide our future expectations or forecasts and can be identified by our use of words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “outlook,” “target,” “predict,” “may,” “will,” “would,” “could,” “should,” “seek,” and other words or phrases of similar meaning in connection with any discussion of future operating or financial performance. This includes annual guidance. Forward-looking statements, by their nature, address matters that are uncertain and involve risks because they relate to events and depend on circumstances that may or may not occur in the future. As a result, our actual results may differ materially from our expected results and from those expressed in our forward-looking statements. 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 report for the quarterly period ended September 30, 2024, that the Company expects to file today. 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, we will be referring to non-Generally Accepted Accounting Principles (“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 are included within this presentation and available on the Investor Relations page of our website at www.armstrongceilings.com. The guidance in this presentation is only effective as of the date given, October 29, 2024, 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, contingent third-party professional fees, changes in the fair value of contingent consideration and deferred compensation accruals for acquisitions). Acquisition related deferred compensation accruals excluded from adjusted EBITDA represented cash and stock awards that were recorded over each award’s respective vesting period, as such payments were subject to the sellers’ and employees’ continued employment with the Company. 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 2024. Our tax rate may be adjusted for certain discrete items which are identified in the footnotes. 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. 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 based on unrounded figures. Operating Segments: “MF”: Mineral Fiber, “AS”: Architectural Specialties, “UC”: Unallocated Corporate 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.
