Lancaster, PA, August 7, 2018. Armstrong Flooring, Inc. (NYSE: AFI) (“Armstrong Flooring” or the “Company”), North America’s largest producer of resilient and wood flooring products, today reported financial results for the second quarter ended June 30, 2018.

Don Maier, Chief Executive Officer, commented, “I am very proud of the Armstrong Flooring team as we delivered both top and bottom line growth in the second quarter, building on our strong start in Q1. Net sales increased 2.9% driven by significant volume growth in Luxury Vinyl Tile (“LVT”) and higher selling prices across most product categories. Adjusted EBITDA growth reflected the combination of higher sales, productivity and cost saving actions that more than offset significant inflationary pressures. Into the second half of 2018, we have a range of initiatives in motion to further advance our strategic priorities and deliver on our reaffirmed full-year 2018 outlook.”

Second Quarter of 2018 Results Compared with Second Quarter of 2017 Results

Consolidated Results

In the second quarter of 2018, net sales increased 2.9% to $306.0 million as compared to $297.3 million in the second quarter of 2017, primarily due to higher Resilient segment net sales.

Second quarter 2018 net income was $10.5 million, or diluted earnings per share of $0.40, as compared to net income of $5.4 million, or diluted earnings per share of $0.20, in the prior year quarter. Adjusted net income was $12.2 million, or adjusted diluted earnings per share of $0.47, as compared to an adjusted net income of $7.5 million, or adjusted diluted earnings per share of $0.27, in the prior year quarter.

Second quarter 2018 adjusted EBITDA was $29.6 million, as compared to $25.5 million in the prior year quarter. The increase in adjusted EBITDA was primarily due to higher net sales, stronger productivity and lower manufacturing costs, which more than offset the impact of significantly higher input costs.

Resilient Flooring Segment

Net sales were $199.9 million as compared to $187.8 million in the prior year period. The increase in net sales was primarily due to double-digit volume growth in LVT, along with higher selling prices and improved mix across most categories.

Operating income was $9.4 million as compared to operating income of $13.5 million in the prior year quarter. Adjusted EBITDA was $21.5 million as compared to $24.0 million in the prior year quarter, primarily attributable to the impact of higher input costs, which more than offset the benefit of improved productivity and higher net sales.

Wood Flooring Segment

Net sales were $106.1 million as compared to $109.5 million in the prior year quarter, with the decline driven by lower volumes in engineered wood. Higher selling prices in both solid and engineered wood provided a partial offset to lower volumes.

Operating income was $4.6 million, compared to an operating loss of $2.3 million in the prior year quarter. Adjusted EBITDA was $8.1 million as compared to $1.5 million in the prior year quarter, driven by improved manufacturing costs and productivity, along with lower SG&A spending, which more than offset higher input costs.

Full Year 2018 Outlook

For the full year 2018, the Company continues to expect adjusted EBITDA to be in the range of $70 million to $80 million. The adjusted EBITDA outlook assumes sales growth in the low single-digits. The Company continues to expect capital expenditures to be in the range of $40 million to $45 million for the full year 2018 while delivering another year of free cash flow in line with recent years.

Supplemental Reconciliations of GAAP to non-GAAP Results (unaudited)

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 restructuring charges and related costs, impairments, the non-cash impact of the U.S. pension plan, and certain other gains and losses. Free cash flow is defined as net cash from operating activities less purchases of property, plant and equipment plus proceeds from the sale of property, plant and equipment. The Company uses these adjusted performance measures in managing the business, including in communications with its Board of Directors and employees, and believes that they can provide users of this financial information with meaningful comparisons of operating performance between current and prior periods. The Company believes that these non-GAAP financial measures are appropriate to enhance understanding of its past performance, as well as its prospects for future performance. A reconciliation of these non-GAAP financial measures 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. The Company does not provide financial guidance for forecasted net income since certain items that impact net income are outside of our control and cannot be reasonably predicted. Therefore, the Company is unable to provide a reconciliation of its Adjusted EBITDA guidance to net income, the most comparable financial measure calculated in accordance with GAAP.
