Item 7.01 Regulation FD Disclosure.

On September 8, 2017, Armstrong World Industries, Inc. issued the following statement in response to litigation filed against it by Roxul USA, Inc. (d/b/a Rockfon) in the United States District Court for the District of Delaware alleging anticompetitive conduct.

“Armstrong World Industries is a recognized global leader in the design and manufacture of innovative commercial and residential ceiling, wall and suspension systems.  For more than 150 years, we have stayed true to our values - delivering superior products to our customers, while competing in a fair and ethical manner.

The litigation recently filed against us by Roxul USA, Inc. (d/b/a Rockfon), a significant ceilings systems competitor with global headquarters in Europe and expanding operations in the Americas, is baseless and we believe its allegations are simply without merit.  We are proud of our broad product portfolio of leading and innovative solutions, our ability to consistently meet architectural and acoustical specifications, our unmatched customer service levels, our dedicated and knowledgeable employees and our trusted Armstrong brand.  Our distributor, contractor and customer relationships reflect voluntary and mutually beneficial arrangements and adhere to all applicable legal requirements. We are confident in our position, look forward to making our case in court and expect to prevail.”

The information in this Current Report on Form 8-K is being furnished herewith and shall not be deemed “filed” for the purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any filing under the Securities Act, or the Exchange Act, except as expressly set forth by specific reference in such filing.

The filing of this Item 7.01 of this Current Report on Form 8-K shall not be deemed an admission as to the materiality of any information herein that is required to be disclosed solely by reason of Regulation FD.
