PG&E Announces New Board Member and Appointment of Special Independent Safety Advisor

Enters Agreement with BlueMountain; Intends to Expand Board at 2019 Annual Meeting and Commence Search for an Additional Independent Director with Clean Energy Expertise/Experience

San Francisco, Calif. —PG&E Corporation (NYSE: PCG) today announced additional changes to the Boards of Directors (the “PG&E Boards” or the “Boards”) of the Corporation and Pacific Gas and Electric Company (together, the “company”) as well as actions aimed at strengthening the company’s safety culture.

Fred Buckman, former CEO of Consumers Energy and PacifiCorp, has been appointed to the Boards as a new independent director, effective immediately. Mr. Buckman will replace Richard Kelly, who has resigned as a director of each of the Boards. PG&E also will be hiring Christopher Hart, former chairman of the National Transportation Safety Board, to serve as a special independent safety advisor. Mr. Hart will report directly to PG&E Corporation CEO and President, Bill Johnson. These announcements follow constructive engagement between PG&E and BlueMountain Capital Management, LLC (together with its affiliates, “BlueMountain”).

“On behalf of the Boards of Directors, I want to thank Dick Kelly for his service and the significant contributions he made to the PG&E Boards over the past six years,” said Nora Mead Brownell, Chair of the Board of PG&E Corporation.

Ms. Brownell continued, “We welcome Fred Buckman to the PG&E Boards. Dr. Buckman brings years of utility operations experience over a multi-state service region, including California, and we are confident his industry background will complement the strengths and expertise of PG&E’s substantially refreshed Boards. Dr. Buckman shares our core belief that safety and operational excellence are critical to the success of PG&E, and is committed to ensuring that these remain the Boards’ highest priorities.”

“We are also pleased to welcome Christopher Hart as an independent safety advisor,” said John Simon, Interim Chief Executive Officer of PG&E Corporation. “As we enter another fire season, we can’t overemphasize the importance of safety. Retaining a former industry regulator with Mr. Hart’s expertise reflects that commitment to strengthening our safety culture. He brings years of administrative experience overseeing complex, hazardous industries to ensure they operate safely. We welcome his insights as we confront the growing wildfire threat and commit to advancing the highest standards of transparency and safety.”

In connection with the changes announced today, the company will propose to increase the maximum size of the PG&E Corporation Board to 15 directors, to be voted on at the Annual Meeting. In filling the fifteenth director position, the PG&E Boards will be focused on identifying candidates with strong clean energy/clean technology experience, a background in network and customer technology, strong ties to California, and expertise in California’s clean energy goals. This agreement further exemplifies PG&E’s commitment to engaging and working with its shareholders and stakeholders to address the state’s evolving energy challenges.

“We appreciate the PG&E Boards’ efforts to engage constructively with shareholders,” commented Andrew Feldstein, BlueMountain’sCo-Founder and Chief Investment Officer. “We believe the changes and other undertakings announced today reflect the Boards’ commitment to improving their governance and oversight. We would also like to acknowledge our independent nominees, whom we have come to know through this process. We thank them for their participation as they return to their individual endeavors now that our nominee slate has been withdrawn.”

PG&E and BlueMountain have entered into an agreement under which BlueMountain will vote all of its shares in favor of each of the company’s Board nominees at the joint 2019 Annual Meeting of Shareholders of PG&E Corporation and Pacific Gas and Electric Company. In addition to withdrawing its slate of directors for election at PG&E’s Annual Meeting, BlueMountain will also abide by customary standstill provisions and voting commitments. Additional information about today’s announcement will be included in a Form8-K Report that will be filed with the U.S. Securities and Exchange Commission (the “SEC”).
