Armstrong World Industries Reports

Fourth Quarter and Full Year 2017 Results

Key Highlights

LANCASTER, Pa., February 26, 2018 -- 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.     

Fourth Quarter Results from Continuing Operations

 

 

Consolidated net sales increased 9.1% compared to the prior year quarter, driven by higher Architectural Specialties volumes and higher average unit values (“AUV”) in which both positive mix and positive like for like pricing contributed.

Operating income increased over the prior year quarter, driven by SG&A savings, volume growth in both segments, positive AUV and net environmental insurance recoveries, offset by higher manufacturing and input costs and costs related to the announced closing of our St. Helens plant.

 

---

“In many ways, 2017 was a transformational year for AWI. Total company sales growth accelerated to 7% after five years of averaging less than 3% growth. Additionally, in November, we entered into an agreement to sell our EMEA and Pacific Rim businesses to Knauf, with an expectation to close in mid 2018,” said Vic Grizzle, CEO. “The pending sale, coupled with the completion of our advanced manufacturing investments, will benefit Armstrong for years to come as we further accelerate top and bottom line performance.”

Additional (non-GAAP*) Financial Metrics from Continuing Operations

 

 

 

 

Consolidated adjusted operating income declined 2% and adjusted EBITDA improved 9% in the fourth quarter, when compared to the prior year quarter. Adjusted EBITDA grew driven by lower SG&A expenses, volume growth in both segments, and solid AUV fall-through to profit, which was offset by manufacturing and input costs and lower equity earnings from WAVE. Adjusted earnings per share reflects a 25% adjusted tax rate in 2017 and a 35% adjusted tax rate in 2016. Adjusted free cash flow improvement was driven primarily by higher cash earnings and lower capital expenditures.

Fourth Quarter Segment Highlights

Effective December 31, 2017, and in connection with the announced sale of our EMEA and Pacific Rim businesses, our EMEA and Pacific Rim segments have been excluded from our results of continuing

operations. As a result, effective December 31, 2017 and for all periods presented, our operating segments are as follows: Mineral Fiber, Architectural Specialties and Unallocated Corporate.

 

Mineral Fiber

 

Net sales increased 3.4%, driven by mid-single digit AUV expansion and slightly higher volume versus the prior year quarter.

 

As reported operating income decreased $1 million, driven mainly by $7 million of costs related to the announced closing of our St. Helens plant and higher manufacturing and input costs, mostly offset by $8 million of net environmental insurance recoveries and the margin impact of higher sales.

 

Architectural Specialties

 

Net sales increased 49.0%, driven by higher volume, led by the Tectum acquisition and increased new construction activity. Operating income increased driven by the margin impact of higher volumes, partially offset by higher SG&A expenses primarily from the Tectum acquisition and investments in selling and design capabilities.

 

Unallocated Corporate

 

Unallocated corporate income of $4.1 million decreased from $5.4 million of expense in the prior year quarter primarily due to U.S. pension income in 2017 compared to U.S. pension expense in 2016.

Full Year Results from Continuing Operations

 

Consolidated net sales increased 6.7% compared to the prior year, driven by higher AUV in which both mix and like for like pricing were positive and higher volume.

3

 

---

 

Operating income increased primarily driven by lower separation costs, $15 million of net environmental recoveries, the margin impact of higher volume, AUV improvement and a decrease in U.S. pension expense, partially offset by $7 million of costs related to the announced closing of our St. Helens plant and higher manufacturing and input costs.

Market Outlook and 2018 Guidance

“Our guidance for 2018 anticipates a slightly more favorable macro-economic climate, but is largely driven by factors within our control,” said Brian MacNeal, CFO. “We expect to deliver improved Average Unit Value (AUV) in our sales, drive productivity savings greater than inflation, and drive cost savings from our restructuring actions in St. Helens and our corporate back office, especially in the second half of the year.”

Earnings Webcast

Management will host a live Internet broadcast beginning at 11:00 a.m. Eastern time today, to discuss fourth quarter and full year results. This event will be broadcast live on the Company's website. To access the call and accompanying slide presentation, go to www.armstrongceilings.com and click Investors.

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 foreign exchange, restructuring charges and related costs, impairments, U.S. pension plan income/expense, separation costs and certain other gains and losses. The Company excludes U.S. pension income/expense in the non-GAAP results as it represents the actuarial net periodic benefit credit/cost recorded as a component of operating income and for all periods presented, the Company was not required and did not make cash contributions to the U.S. Retirement Income Plan based on guidelines established by the Pension Benefit Guaranty Corporation, nor does the Company expect to make cash contributions to the plan in 2018. Adjusted free cash flow is defined as cash from operations and dividends received from the WAVE joint venture, less expenditures for property and equipment, and is adjusted to remove the impact of cash used or proceeds received for acquisitions and divestitures. The Company believes adjusted free cash flow is useful because it provides insight into the amount of cash that the Company has available for discretionary uses, after expenditures for capital commitments and adjustments for acquisitions and divestitures. Adjusted figures are reported in comparable dollars using the budgeted exchange rate for 2017. 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. 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.

In addition, we will be referring to non-GAAP financial measures within the meaning of SEC Regulation G.

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 the 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. Basis of Presentation Explanation Results throughout this presentation are presented on a continuing operations basis with the exception of cash flow. With the pending sale of our EMEA and Pacific Rim businesses, we no longer adjust our sales for movements in foreign exchange rates as we expect these to have minimal impact on revenue. We remove the impact of certain discrete expenses and income. Examples include plant closures, restructuring actions, separation costs, environmental site expenses and related insurance recoveries, and other large unusual items. We also adjust for our U.S. pension plan (credit) expense(1). Taxes for adjusted net income and adjusted diluted EPS are calculated using a constant 25% rate for 2017 and 2018 guidance. Historical results are presented at a 35% rate. Segment SG&A cost structures reflect updated cost allocation methodology. U.S. pension (credit) expense represents the actuarial net periodic benefit cost expected to be recorded as a component of operating income. 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, nor do we expect to make cash contributions to the plan in 2018.

Adjusted Free Cash Flow Reconciliation Adjusted free cash flow is defined as cash from operations and dividends received from the WAVE joint venture, less expenditures for property and equipment, and is adjusted to remove the impact of cash used or proceeds received for acquisitions and divestitures. The Company believes adjusted free cash flow is useful because it provides insight into the amount of cash that the Company has available for discretionary uses, after expenditures for capital commitments and adjustments for acquisitions and divestitures. Free cash flow includes discontinued international operations.

ARMSTRONG WORLD INDUSTRIES INVESTOR PRESENTATION February 26, 2018 Exhibit 99.3

Safe Harbor Statement Our disclosures in this presentation, including without limitation, those relating to future financial results guidance, 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. 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 recent reports on Forms 10-K and 10-Q filed with the U.S. Securities and Exchange Commission (“SEC”). As a result, our actual results may differ materially from our expected results and from those expressed in our forward-looking statements. 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. The information in this presentation is only effective as of the date given February 26, 2018 and is subject to change. Any distribution of this presentation after February 26, 2018 is not intended and will not be construed as updating or confirming such information. 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 can be found in the appendix to this presentation, in our SEC filings and on the Investor Relations section of our website at www.armstrongceilings.com. Armstrong World Industries competes globally in many diverse markets. References to "market" or "share" data are simply estimations based on a combination of internal and external sources and assumptions. They are intended only to assist discussion of the relative performance of product segments and categories for marketing and related purposes. No conclusion has been reached or should be reached regarding a "product market," a "geographic market" or “market share,” as such terms may be used or defined for any economic, legal or other purpose.

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 the 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. Basis of Presentation Explanation Results throughout this presentation are presented on a continuing operations basis with the exception of cash flow. With the pending sale of our EMEA and Pacific Rim businesses, we no longer adjust our sales for movements in foreign exchange rates as we expect these to have minimal impact on revenue. We remove the impact of certain discrete expenses and income. Examples include plant closures, restructuring actions, separation costs, environmental site expenses and related insurance recoveries, and other large unusual items. We also adjust for our U.S. pension plan (credit) expense(1). Taxes for adjusted net income and adjusted diluted EPS are calculated using a constant 25% rate for 2017 and 2018 guidance. Historical results are presented at a 35% rate. Segment SG&A cost structures reflect updated cost allocation methodology. U.S. pension (credit) expense represents the actuarial net periodic benefit cost expected to be recorded as a component of operating income. 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, nor do we expect to make cash contributions to the plan in 2018.

Adjusted Free Cash Flow Reconciliation Adjusted free cash flow is defined as cash from operations and dividends received from the WAVE joint venture, less expenditures for property and equipment, and is adjusted to remove the impact of cash used or proceeds received for acquisitions and divestitures.
