LANCASTER, Pa., February 23, 2021 -- Armstrong World Industries, Inc. (NYSE:AWI), a leader in the design, innovation and manufacture of commercial and residential ceiling, wall and suspension system solutions, today reported financial results for the fourth quarter and full year 2020.
Fourth Quarter Results from Continuing Operations
| (Dollar amounts in millions except per-share data) | For the Three Months Ended December 31, | ||||||
|---|---|---|---|---|---|---|---|
| 2020 | 2019 | Change | |||||
| Net sales | $ | 238.7 | $ | 246.9 | (3.3 | )% | |
| Operating income | $ | 44.1 | $ | 62.2 | (29.1 | )% | |
| Earnings from continuing operations | $ | 34.8 | $ | 51.5 | (32.4 | )% | |
| Diluted earnings per share | $ | 0.72 | $ | 1.04 | (30.8 | )% |
Net sales decreased compared to the prior year quarter, driven by lower volume in both the Mineral Fiber and Architectural Specialties segments as a result of lower market demand due to COVID-19, as well as unfavorable Mineral Fiber Average Unit Value (“AUV”) primarily due to unfavorable channel mix and regional weakness in major metropolitan areas heavily impacted by COVID-19, partially offset by the positive sales impact of 2020 and 2019 acquisitions.
Operating income decreased from the prior year quarter, driven primarily by lower sales volume in the Mineral Fiber segment and higher SG&A costs related to growth initiatives, partially offset by improved manufacturing productivity.

“2020 was an extraordinary year with social, economic and health crises all contributing to new and unusual operating challenges. I am extremely proud that Armstrong was able to advance our strategic initiatives in the face of those challenges, as our teams quickly adapted to new ways of working in order to continue the pursuit of our strategic priorities. We continued to invest in digital tools and initiatives, we launched over thirty new products, including many with a focus on Healthy Spaces, and we completed three acquisitions, including Arktura in December.” said Vic Grizzle, President and CEO of Armstrong. “Notwithstanding the impacts of COVID-19, we again demonstrated the strength of our business model, as we delivered over $200 million of free cash flow.”
Additional (non-GAAP*) Financial Metrics from Continuing Operations
| (Dollar amounts in millions except per-share data) | For the Three Months Ended December 31, | ||||||
|---|---|---|---|---|---|---|---|
| 2020 | 2019 | Change | |||||
| Adjusted EBITDA | $ | 73 | $ | 90 | (18.9 | )% | |
| Adjusted net income | $ | 37 | $ | 55 | (32.2 | )% | |
| Adjusted diluted earnings per share | $ | 0.77 | $ | 1.11 | (30.6 | )% | |
| Adjusted free cash flow | $ | 68 | $ | 71 | (4.6 | )% |
* The Company uses the above non-GAAP adjusted measures in managing the business and believes the adjustments provide meaningful comparisons of operating performance between periods. The Company also believes that the adjustments help users of our financial information understand the effect of those adjusted items on our selected reported results and provide useful alternative measurements of performance. See Supplemental Reconciliations of GAAP to non-GAAP results (below) for a breakdown of the adjustments and a reconciliation of the selected reported results to these non-GAAP measures.
| (Dollar amounts in millions) | For the Three Months Ended December 31, | ||||||
|---|---|---|---|---|---|---|---|
| 2020 | 2019 | Change | |||||
| Adjusted EBITDA | |||||||
| Mineral Fiber | $ | 66 | $ | 81 | (19.1 | )% | |
| Architectural Specialties | 7 | 8 | (16.0 | )% | |||
| Consolidated Adjusted EBITDA | $ | 73 | $ | 90 | (18.9 | )% |
Consolidated adjusted EBITDA declined (19)% in the fourth quarter when compared to the same prior year period, driven primarily by unfavorable channel mix and a decrease in WAVE earnings, partially offset by improved manufacturing productivity. Adjusted free cash flow declined primarily due to lower cash earnings driven by volume declines, partially offset by working capital improvements.
Fourth Quarter Segment Highlights
Mineral Fiber
| (Dollar amounts in millions) | For the Three Months Ended December 31, | ||||||
|---|---|---|---|---|---|---|---|
| 2020 | 2019 | Change | |||||
| Net sales (as reported) | $ | 183.1 | $ | 197.2 | (7.2 | )% | |
| Operating income (as reported) | $ | 45.0 | $ | 59.1 | (23.9 | )% | |
| Adjusted EBITDA | $ | 66 | $ | 81 | (19.1 | )% |

Mineral Fiber net sales decreased due to lower volume and unfavorable AUV. Unfavorable AUV was driven primarily by unfavorable channel mix and regional weakness in major metropolitan areas heavily impacted by COVID-19. Like for like price was positive in the quarter.
Operating income decreased in the fourth quarter primarily due to the negative impact of lower sales volume, higher SG&A spend, lower WAVE earnings and the impact of unfavorable AUV, partially offset by improved manufacturing productivity and a reduction in incentive compensation expenses.
Architectural Specialties
| (Dollar amounts in millions) | For the Three Months Ended December 31, | ||||||
|---|---|---|---|---|---|---|---|
| 2020 | 2019 | Change | |||||
| Net sales (as reported) | $ | 55.6 | $ | 49.7 | 11.9 | % | |
| Operating income (as reported) | $ | 1.4 | $ | 5.6 | (75.0 | )% | |
| Adjusted EBITDA | $ | 7 | $ | 8 | (16.0 | )% |
Net sales in Architectural Specialties increased by 12% due to sales from the recent acquisitions of Turf Design, Moz Designs and Arktura, LLC mostly offset by a reduction in demand as a result of COVID-19.
Operating income decreased due to the negative impact of lower sales volume, excluding the impact of the 2020 acquisitions, as well as additional amortization expense related to acquisitions.
Unallocated Corporate
Unallocated corporate expense of $2.3 million decreased from $2.5 million of expense in the prior year quarter.
Year to Date Results from Continuing Operations
| (Dollar amounts in millions) | For the Year Ended December 31, | ||||||
|---|---|---|---|---|---|---|---|
| 2020 | 2019 | Change | |||||
| Net sales (as reported) | $ | 936.9 | $ | 1,038.1 | (9.7 | )% | |
| Operating income (as reported) | $ | 254.8 | $ | 317.4 | (19.7 | )% | |
| Adjusted EBITDA | $ | 330 | $ | 403 | (18.1 | )% | |
| Adjusted free cash flow | $ | 212 | $ | 244 | (13.0 | )% |
Net sales decreased driven mainly by lower volumes in both the Mineral Fiber and Architectural Specialties segments as a result of COVID-19 and unfavorable AUV in the Mineral Fiber segment.
Operating income decreased from the prior year period, primarily due to the impact of decreased sales and lower WAVE earnings, which was partially offset by lower SG&A expenses, the gain on sale of the idled China plant, and improved manufacturing productivity.

Adjusted Free Cash Flow (FCF) decreased from the prior year period, driven by lower cash generated from operating activities as a result of COVID-19 and lower equity earnings from WAVE. Adjusted FCF for the year is 23% as a percent of sales, or 121% of adjusted net income.
Market Outlook and 2021 Guidance
“We continue to expect sequential improvements in our end markets as market conditions improve and vaccinations allow businesses to return to more normal operations,” said Brian MacNeal, CFO of Armstrong. “With our growth initiatives, including Healthy Spaces and kanopi, and the year-on-year benefit of our 2020 acquisitions, we expect to grow sales 10% to 13% in 2021. We expect this sales growth, together with continued productivity in our plants, to deliver adjusted EBITDA growth of 9% to 13%, and, after a step up in capital expenditures, to drive a free cash flow margin of 19%.”

Supplemental Reconciliations of GAAP to non-GAAP Results (unaudited)
(Amounts in millions, except per share data)
To supplement its consolidated financial statements presented in accordance with accounting principles generally accepted in the United States (“GAAP”), the Company provides additional measures of performance adjusted to exclude the impact of certain discrete expenses and income. Investors should not consider non-GAAP measures as a substitute for GAAP measures. The Company excludes certain acquisition related expenses (i.e. – changes in the fair value of earnouts, deferred compensation accruals, impact of adjustments related to the fair value of inventory and deferred revenue) for recent acquisitions. 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. Examples of other excluded items include plant closures, restructuring charges 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 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 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 2021. 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, legacy environmental matters and litigation. The Company believes adjusted free cash flow is useful because it provides insight into the amount of cash that the Company generates for discretionary uses, after expenditures for capital investments and adjustments for acquisitions and divestitures. The Company uses these adjusted performance measures in managing the business, including communications with its Board of Directors and employees, and believes that they provide users of this financial information with meaningful comparisons of operating performance between current results and results in prior periods. The Company believes that these non-GAAP financial measures are appropriate to enhance understanding of its past performance, as well as prospects for its future performance. The Company also uses adjusted EBITDA and adjusted free cash flow as factors in determining at-risk compensation for senior management. These non-GAAP measures may not be defined and calculated the same as similar measures used by other companies. A reconciliation of these adjustments to the most directly comparable GAAP measures is included in this release and on the Company’s website. These non-GAAP measures should not be considered in isolation or as a substitute for the most comparable GAAP measures. Non-GAAP financial measures utilized by the Company may not be comparable to non-GAAP financial measures used by other companies.
In the following charts, numbers may not sum due to rounding.

Earnings Call Presentation 4th Quarter 2020 February 23, 2021 Exhibit 99.2

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. 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 Forms 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 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, February 23, 2021 and will not be updated or affirmed unless and until we publicly announce updated or affirmed guidance Safe Harbor Statement

All figures throughout the presentation are in $ millions unless otherwise noted. Figures may not add due to rounding. When reporting our financial results within this presentation, we make several adjustments. Management uses these non-GAAP measures in managing the business and believes the adjustments provide meaningful comparisons of operating performance between periods. As reported results will be footnoted throughout the presentation on a continuing operations basis (excludes corporate unallocated). Basis of Presentation Explanation Results throughout this presentation are presented on a normalized basis with the exception of cash flow. We remove the impact of certain discrete expenses and income. The Company excludes certain acquisition related expenses (i.e. – changes in the fair value of earnouts, deferred compensation accruals, impact of adjustments related to the fair value of inventory and deferred revenue) for recent acquisitions(1). 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 other large unusual items. We also adjust for our U.S. pension plan (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. 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. U.S. pension (credit) expense represents the actuarial net periodic benefit cost expected to be recorded as a component of earnings from continuing operations. For all periods presented, we were not required and did not make cash contributions to our U.S. Retirement Income Plan based on guidelines established by the Pension Benefit Guaranty Corporation.
