Aleks’ in-depth knowledge of the automotive industry, experience leading transformational initiatives and significant legal expertise will make her a valuable addition to our recently refreshed boardroom. I look forward to working with Aleks and the other directors as we continue to oversee the successful execution of Tenneco’s strategy to deliver on our strategic and financial objectives.”

“I am honored to join Tenneco’s Board at this important time,” said Ms. Miziolek. “I look forward to working with my fellow directors and the management team to build on Tenneco’s momentum and capitalize on the opportunities ahead.”

“We are grateful to David for his invaluable contributions to our Board during his many years of service as a Tenneco director,” said Gregg Sherrill, Chairman of the Board. “His strategic, operational and financial counsel have helped guide management as the Company has worked through significant changes and successfully navigated our dynamic industry.”

The Company also today announced that it entered into a Cooperation Agreement with Protean Services LLC (“Protean”), a stockholder of the Company. Under the terms of the agreement, Protean will withdraw its slate of directors and vote all of its shares in favor of each of the Tenneco Board’s nominees at the Company’s upcoming Annual Meeting. Protean will also be subject to certain customary standstill provisions for a one-year period ending prior to the 2021 Annual Meeting. The full agreement between Tenneco and Protean will be filed on a Form 8-K with the U.S. Securities and Exchange Commission (the “SEC”).

“Over the past three months, Tenneco has taken a number of positive steps to strengthen its corporate governance practices, including refreshing its Board with highly qualified individuals and reconstituting its board committees to further improve oversight of management,” said Daniel Ninivaggi, Managing Member of Protean. “I support the governance actions the Board has taken and believe in the Company’s long-term prospects.”

Lazard served as a strategic advisor and Kirkland & Ellis LLP served as legal counsel with respect to the Cooperation Agreement and the Board refreshment process.
