Item 5.02 Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers.
The Board of Directors (the “Board”) of Preformed Line Products Company (the “Company”) announces with great sadness that Michael E. Gibbons, a long-tenured director of the Company, passed away unexpectedly on September 14, 2025. Mr. Gibbons had been a director since 2008 and served as the Chairman of the Audit Committee and a member of the Compensation Committee. He was a valued and dedicated member of the Board and will be remembered for the business acumen, integrity and leadership he brought to the Board and the Company. In addition to his significant contributions to the Board and the Company over the last 17 years, Mr. Gibbons had a long and distinguished career at Brown Gibbons Lang & Company, an investment bank and financial advisory firm he founded in 1989, and was an influential figure in Northeast Ohio, involved in numerous philanthropic and charitable organizations. We are profoundly grateful for his years of guidance, insight, and dedication to the Company. He will be greatly missed, and the Company extends its deepest condolences to his family, friends and colleagues.
Due to the vacancy created by Mr. Gibbons’ passing, the Board reduced the size of the Board to be eight directors. The Board also appointed Matthew D. Frymier, a current member of the Board and the Audit Committee, to serve as Chairman of the Audit Committee and R. Steven Kestner, a current member of the Board and Compensation Committee, to serve as a member and as Chairman of the Compensation Committee, replacing Mr. Frymier as Chairman of such committee.
