Paroc Purchase Agreement

On October 27, 2017, Owens Corning Finland Oy (“Acquisition Sub”), a subsidiary of Owens Corning (the “Company”), entered into an agreement (the “Purchase Agreement”) with Parry Investment S.A. (the “Paroc Seller”) and certain individuals (the “Management Warrantors”), for Acquisition Sub to acquire (the “Acquisition”) all of the capital stock of Parry I Holding AB (the “Paroc Target”). The Paroc Target owns Paroc Group Oy (“Paroc”), a leading producer of mineral wool for building and technical insulation products and solutions in Europe.

Acquisition Sub will acquire the Paroc Target at closing for an enterprise value of approximately €900 million in cash. The Acquisition is expected to be financed through a combination of long-term debt and pre-payable bank financings.

The closing of the Acquisition, which is expected to occur in early 2018, is subject to the satisfaction or waiver of customary closing conditions, including: (1) the receipt of certain antitrust approvals, and (2) there being no material breach of certain fundamental warranties.

The Acquisition Sub and the Paroc Seller have each agreed to use reasonable best efforts to cause the Acquisition to be consummated and the Acquisition Sub has agreed to use its best efforts to obtain the necessary antitrust approvals at the first stage of the relevant authority’s review process. The Purchase Agreement includes termination provisions for both Acquisition Sub and the Paroc Seller under specified circumstances including, without limitation, (1) a material adverse effect allowing Acquisition Sub to terminate, (2) failure by the other party to satisfy certain closing covenants, (3) failure by Acquisition Sub to obtain the necessary antitrust approvals, or (4) failure to meet conditions to closing by April 27, 2018, a date that can be extended by the Paroc Seller for up to two months.

A press release regarding the proposed Acquisition is attached hereto as Exhibit 99.1, which is incorporated herein by reference.

The information in Item 7.01 of this Current Report on Form 8-K shall not be deemed to be “filed” for the purposes

of Section 18 of the Securities Act of 1933, or the Securities Exchange Act of 1934, except as shall be expressly set forth by specific reference in such a filing.
