Armstrong World Industries : First Quarter 2026 Earnings Presentation

AWI

Published on 04/28/2026 at 06:44 am EDT

1st Quarter 2026 Earnings Presentation

April 28, 2026

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 based on unrounded figures. 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.
