Our Board believes that each director should be committed to serving on our Board for an extended period of time and to devoting sufficient time to carry out the director’s duties and responsibilities in an effective manner for the benefit of our shareholders. Our Board’s Corporate Governance Guidelines require each director to promptly notify the Governance Committee Chair before accepting any invitation to serve on the board of anyfor-profit business entity. The Governance Committee evaluates and advises whether it believes service on such outside board would interfere with the director’s service on our Board.

Our Board recognizes that the public company commitments of our director, John Plant, who also serves as the Chair of the Board and Chief Executive Officer of Howmet Aerospace Inc. and as a member of Jabil Inc.’s board, exceed the policies of certain of our shareholders and of proxy advisors. Our Board believes that Mr. Plant has been a highly valued member of our Board since 2012, has demonstrated his active engagement through his consistent attendance and participation with Board matters, both during andin-between Board meetings, and that he has the time and ability to fulfill his obligations to our Board. During the past three years, Mr. Plant has attended 95% of all of our Board and

Committee meetings of which he is a member. He brings to our Board uniquely deep expertise in leading complex and efficient business and manufacturing operations and executing significant M&A transactions, as well as capital allocation strategies, all of which drivetop-and bottom-line growth and long-term shareholder value creation. After robust and thorough discussion and consideration of Mr. Plant’s contributions to our Board, and his demonstrated continued focus and attention to our Company, our Board uniformly believes that his continued service as a director is in the best interest of our Company and our shareholders and recommends Mr. Plant forre-election at our Annual Meeting.
