ARMSTRONG FLOORING REPORTS THIRD QUARTER 2021 RESULTS

Third Quarter 2021 Highlights

• Net sales of $168.5 million

• Net loss of $29.7 million

• Adjusted EBITDA loss of $17.9 million

LANCASTER, Pa – November 4, 2021. Armstrong Flooring, Inc. (NYSE:AFI) (“Armstrong Flooring” or the “Company”) a leader in the design and manufacture of innovative flooring solutions, today reported financial results for the third quarter ended September 30, 2021.

Michel Vermette, President and Chief Executive Officer, commented, “During the third quarter we were able to grow our sales by approximately 8% year-over-year, and we continue to see strong demand for our products, carrying an order backlog of approximately $67 million into the fourth quarter. However, we experienced further supply chain disruptions and inflationary pressures that significantly impacted our profitability. While we are disappointed with our results, we are proactively taking measures to address these issues. To that point, we followed-up on our August price increase by announcing the largest set of comprehensive pricing actions in our history, which became effective November 1^st. Additionally, we curtailed our capital expenditures and planned SG&A spend in the third quarter and have taken actions to continue to reduce this spend in the near term. Finally, we are continuing to work to address the disruptions to our supply chain and are expecting a large volume of incoming sourced material in the fourth quarter to help address our backlog and support our go-to-market transformation.”

Amy Trojanowski, Chief Financial Officer, stated, “As announced in our filings with the U.S. Securities and Exchange Commission today, we negotiated amendments to our Credit and Term Loan facilities, which will provide us financial covenant relief through at least December 31, 2021, and which will allow us to work with our lenders to evaluate options for long-term relief. We are in on-going discussions with our lenders and expect to make additional comments concerning these discussions before the end of this year. During the quarter, we took a concerted look at our Transformation Plan initiatives, electing to postpone certain marketing and merchandising activities, reducing planned SG&A in the quarter, and balancing this external spend with long-term strategic goals. In October we announced a temporary furlough and further headcount reductions which are expected to result in approximately $4 million of cost savings on a go-forward basis. These initiatives, along with our recently announced pricing actions, are designed to improve our financial position in the near-term.”

Mr. Vermette, added, “We are balancing these near-term initiatives with the long-term strategic goals of our multi-year Transformation Plan to expand our customer reach, simplify our portfolio and operations, and strengthen our capabilities. We are pleased to have an established direct residential salesforce and to have launched several new products that have been well received by our customers and the market. Looking ahead, our focus into 2022 is to capture the return on these investments while addressing recent financial obstacles and continuing to optimize our cost structure.”

Net sales in the third quarter increased 7.6% to $168.5 million compared to $156.6 million in the third quarter of 2020, reflecting growth in the Company’s North American, China, and Australian business. In North America, recent pricing initiatives and favorable product mix offset slower supply chain related end-of-quarter volumes in Commercial and Residential channels, while sales recovery from the pandemic drove improved results in the Company’s China and Australian businesses.

Operating loss in the third quarter was $28.8 million compared to a loss of $10.1 million in the third quarter of 2020, primarily the result of cumulative inflation in our product costs along with higher domestic and ocean freight, which continued to outpace pricing actions resulting in lower gross profit compared to the prior year. Third quarter operating results were hampered by an additional $21 million of inflation when compared to the third quarter of 2020, with pricing initiatives serving to offset approximately 43% of these costs. Selling, general, and administrative expenses were $41.7 million for the quarter, versus $37.7 million in the third quarter 2020, with the increase reflective of more normalized spend versus pandemic levels in the prior year. Year-over-year increases were mainly attributable to $3.6 million in higher cost associated with salaries, benefits and normalized travel for our expanded sales force and higher marketing and merchandising expenses associated with our change in go-to-market, $2.5 million in normalized corporate support expenses, partially offset by $2.1 million of lower IT and consulting spend, along with the benefits of lower facility costs associated with the Company’s headquarter relocation completed in the first half of 2021.

Net loss in the third quarter of 2021 was $29.7 million, or diluted loss per share of $1.34, compared to a net loss of $11.7 million, or diluted loss per share of $0.53, in the third quarter of 2020. Adjusted net loss was $31.0 million, or adjusted diluted loss per share of $1.40, compared to an adjusted net loss of $11.3 million, or adjusted diluted loss per share of $0.51, in the prior year quarter.

Third quarter 2021 adjusted EBITDA was a loss of $17.9 million, compared to adjusted EBITDA of $2.8 million in the prior year quarter. The difference in adjusted EBITDA was primarily due to higher input costs, driven by the inflationary impacts of both raw materials and shipping costs, along with higher selling, general & administrative expenses in 2021, as well as lower operating expenses in the third quarter 2020, due to the COVID-19 related environment.

Liquidity and Capital Resources Update

At September 30, 2021, the Company had total liquidity of approximately $76.8 million including $14.9 million of cash plus availability under its credit facilities. The Company’s Net Debt on September 30, 2021, was $59.2 million.

Free cash flow is a non-GAAP financial measure and consists of Net cash provided by (used for) operating activities less capital expenditures net of proceeds from asset sales. The Company’s management believes Free cash flow is meaningful to investors because management reviews Free cash flow in assessing and evaluating performance. However, this measure should be considered in addition to, rather than a substitute for Cash flows provided by (used for) operating activities provided in accordance with GAAP. The Company’s method of calculating Free cash flow may differ from methods used by other companies and, as a result, Free cash flow may not be comparable to other similarly titled measures disclosed by other companies.

Adjusted net income (loss) is a non-GAAP financial measures and consists of Net income (loss) adjusted to remove the impact of business transformation items, U.S. pension expense, other (income) expense, net; and adjust such items for the related tax impacts. Adjusted diluted earnings (loss) per share is a non-GAAP financial measure and consists of Adjusted net income (loss) divided by weighted average diluted shares outstanding for the corresponding period. The Company’s management believes Adjusted net income (loss) and Adjusted diluted earnings (loss) per share are meaningful to investors because management reviews Adjusted net income (loss) and Adjusted diluted earnings (loss) per share in assessing and evaluating performance.
