Paragon Offshore Announces Confirmation of Restructuring Plan

06/07/2017

HOUSTON, June 07, 2017 (GLOBE NEWSWIRE) — Paragon Offshore plc (“Paragon” or the “company”) (OTC:PGNPQ) announced today that the United States Bankruptcy Court has approved the company’s consensual plan of reorganization (the “Consensual Plan”) under chapter 11 of the United States Bankruptcy Code that the company announced on May 2, 2017. Under the Consensual Plan, Paragon’s existing equity will be deemed worthless and the company’s secured creditors and unsecured bondholders will receive equity in a new reorganized parent company. In confirming the plan, the Bankruptcy Court overruled all objections raised at confirmation, including those raised by an unofficial committee of equity holders.

Paragon is planning for its emergence from chapter 11 in early July; however, this timing is subject to the completion of certain conditions precedent to emergence including, among other things, Paragon’s legal entity restructuring.

Following the ruling, Mr. Dean E. Taylor, President and Chief Executive Officer of Paragon, said, “We are extremely gratified to have received this ruling. Thanks are due to our employees, our board of directors, our creditors, and the professionals retained by Paragon and its creditors. Without their hard work and dedication, we could not have achieved this result, which allows us to emerge from the shadow of bankruptcy and return to our core business of delivering Safe, Reliable, and Efficient services to our customers.”

Additional Information

Details of the Consensual Plan can be found in the Current Report on Form 8-K filed by the company with the U.S. Securities and Exchange Commission (the “SEC”) on May 3, 2017.
