GALION, Ohio – August 1, 2005 – PECO II, Inc. (Nasdaq:PIII) announced today the appointment of John G. Heindel, 50, as President and Chief Executive Officer of the Company. Mr. Heindel, a telecommunications industry veteran who guided the formation of Lucent Worldwide Services, succeeds James L. Green, 77, who previously announced his retirement as President and CEO.
Mr. Green will continue to serve as a member of the Board of Directors and has been elected Chairman. In that capacity he succeeds Matthew P. Smith, who remains on the Board. Mr. Heindel has been appointed to the Board for a two year term.
PECO II is a full-service provider of engineering and installation on- site services and manufacturer of communications power systems and equipment to the communications industry.
“John Heindel is a strong leader whose demonstrated success in delivering revenue and profit growth in competitive arenas is ideally suited for PECO II as it takes advantage of markets that appear to be increasingly favorable,” said Mr. Green. “With our stable operations, cash flow and balance sheet, and major new contracts in place, we now embark on an exciting period under his direction.”
Mr. Heindel said, “Our entire industry while still facing significant challenges is positioned for growth. PECO II has a rich history of service to its customers and I am excited to become a member of its leadership team. Leveraging our competencies and solid balance sheet with a strong focus on our customers will afford us the opportunity to win in today’s very competitive market place. I look forward to working with the team in taking PECO II to the next level.”
Mr. Heindel spent more than 22 years with Lucent Technologies and its predecessor companies, most recently as president, Worldwide Services. In that capacity, he was responsible for the formation of Lucent Worldwide Services and led the services business to profitability despite the severe industry downturn.
