Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
On March 12, 2026, as a result of a reduction in the number of directors that certain stockholders are entitled to designate for election to the Board of Directors (the “Board”) of Sotera Health Company (the “Company”), Constantine S. Mihas notified the Board of his intention to resign as a Class I director, effective March 16, 2026. Mr. Mihas’ resignation was not the result of any disagreement with the Company on any matter relating to its operations, policies or practices.
On March 15, 2026, the Board appointed Kenneth D. Krause as a Class I director of the Board, effective March 16, 2026.
Mr. Krause has served as Executive Vice President and Chief Financial Officer of Rollins, Inc. (“Rollins”), a global consumer and commercial pest control services company, since September 2022. In 2024, his role expanded to include oversight of Rollins’ International Brands. During his tenure at Rollins, he has led modernization initiatives that have driven improvements in growth, profitability, capital allocation and access to capital, enabling strong shareholder returns. Prior to joining Rollins, Mr. Krause served as Senior Vice President, Chief Financial Officer, Chief Strategy Officer and Treasurer of MSA Safety Incorporated (“MSA Safety”) from December 2015 to September 2022, after holding positions of increasing responsibility in the finance function at MSA Safety from 2006 to 2015. At MSA Safety, he led value creation initiatives that drove transformational change in the growth and profitability profile of the company. Earlier in his career, Mr. Krause served as a Senior Manager in the audit practice of KPMG LLP. He holds a Bachelor of Science in Business Administration in Accounting from Slippery Rock University and an M.B.A. from the University of Pittsburgh Katz Graduate School of Business and is a Certified Public Accountant (inactive) in Pennsylvania. Mr. Krause will serve as a member of the Audit Committee and the Litigation Committee of the Board.
Mr. Krause is entering into a customary indemnification agreement with the Company in connection with his appointment as a director, consistent with those entered into with the Company’s other directors, pursuant to which the Company agrees to provide indemnification and advancement of expenses to the fullest extent permitted by law and the Company’s amended and restated certificate of incorporation and amended and restated bylaws. Mr. Krause has been deemed to be “independent” in accordance with Rule 5605(a)(2) of the Nasdaq Listing Rules. There is no arrangement or understanding between Mr. Krause and any other persons pursuant to which Mr. Krause was appointed to serve on the Board. Additionally, there are no reportable transactions between Mr. Krause and the Company that require disclosure pursuant to Item 404(a) of Regulation S-K. As a director of the Company, Mr. Krause will receive compensation as a non-employee director in accordance with the Company’s non-employee director compensation policy as described in the Company’s Definitive Proxy Statement on Schedule 14A, filed with the U.S. Securities and Exchange Commission on April 10, 2025, as amended and supplemented, which generally consists of an annual cash retainer for Board service and an annual grant of restricted stock units.
