Safe Harbor Statement Our disclosures in this presentation, including without limitation, those relating to future financial results market conditions and guidance, the impacts of COVID-19 on our business, and in our other public documents and comments contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act. 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 both annual guidance and five-year growth targets which represent internal company estimates at a five-year compounded annual growth rate. 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 may affect our ability to achieve the projected performance is included in the “Risk Factors” and “Management’s Discussion and Analysis” sections of our reports on Form 10-K and 10-Q filed with the U.S. Securities and Exchange Commission (“SEC”). 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-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 Generally Accepted Accounting Principles (“GAAP”) are included within this presentation and available on the Investor Relations pageof our website at www.armstrongceilings.com. The guidance in this presentation is only effective as of the date given, April 26, 2022, 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 net sales, adjusted EBITDA, adjusted diluted earnings per share (EPS) and adjusted free cash flow. The Company excludes certain acquisition related expenses (i.e. – changes in the fair value of earn-outs, deferred compensation accruals(1), impact of adjustments related to the fair value of inventory and deferred revenue) for recent acquisitions. The Company excludes all acquisition-related amortization from adjusted earnings from continuing operations and in calculations of adjusted diluted earnings per share. Examples of other excluded items include plant closures, restructuring actions and related costs, impairments, separation costs, environmental site expenses and related insurance recoveries, endowment level charitable contributions, and certain other gains and losses. The Company also adjusts for our U.S. Retirement Income Plan (RIP) (credit) expense(2). Our tax rate may be adjusted for certain discrete items which are identified in the footnotes. Investors should not consider non-GAAP measures as a substitute for GAAP measures. Non-GAAP figures are rounded to the nearest million and corresponding percentages are rounded to the nearest percent based on unrounded figures. The deferred compensation accruals are for cash and stock awards that will be recorded over the vesting period, as such payments are subject to the sellers’ and employees’ continued employment with the Company. RIP (credit) expense represents the entire actuarial net periodic pension (credit) expense recorded as a component of earnings from continuing operations. For all periods presented, we were not required to and did not make cash contributions to our RIP. All dollar figures throughout the presentation are in $ millions, except per share data, and all comparisons are versus prior year unless otherwise noted. Figures may not sum due to rounding.
