HW Headwaters Incorporated (delisted)

Item 8.01. Other Events.

As previously disclosed, on November 20, 2016, Headwaters Incorporated (the “ Company ”) entered into an Agreement and Plan of Merger (the “ Merger Agreement ”) with Boral Limited (“ Boral ”) and Enterprise Merger Sub, Inc., a wholly-owned subsidiary of Boral (“ Merger Sub ”), providing for the merger of Merger Sub with and into the Company (the “ Merger ”), with the Company surviving the Merger as a wholly-owned subsidiary of Boral.

Also as previously reported, on January 5, 2017, in consultation with the Company, Boral voluntarily withdrew its Premerger Notification and Report Form (the “ HSR Filing ”), effective at 5:00 pm ET on January 6, 2017, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “ HSR Act ”), in connection with the Merger.  Boral re-filed the HSR Filing on January 10, 2017 and, as a result, the waiting period under the HSR Act with respect to the transactions contemplated by the Merger Agreement was scheduled to expire at 11:59 pm ET on February 9, 2017, unless such period was terminated earlier or extended.

On February 9, 2017, each of the Company and Boral received a Request for Additional Information and Documentary Materials, commonly referred to as a “second request,” from the U.S. Federal Trade Commission (the “ FTC ”). The FTC’s second request has the effect of extending the waiting period under the HSR Act until 30 days after the parties substantially comply with the request, unless the waiting period is extended voluntarily by the parties or terminated earlier by the FTC. The Company and Boral intend to continue to cooperate fully with the FTC in connection with its review.

In addition to the expiration or termination of the applicable waiting period under the HSR Act, completion of the transaction remains subject to the satisfaction or waiver of other customary closing conditions as set forth in the Merger Agreement. The parties continue to expect that the transaction will be completed in mid-calendar year 2017.
