Mr. Macricostas has over 30 years of technical and management experience in business operations and information technology. He has been a member of the Photronics Board of Directors since 2002, serving on the Nomination and Cybersecurity committees, and most recently as Chairman of the Compensation Committee.

Mr. Macricostas was a Founder, Chairman, and CEO of RagingWire Data Centers, Inc., a provider of mission critical data center colocation facilities, which is where the “Cloud” lives. He guided the company through a two-stage sale to NTT of Japan in 2014 and 2018. Previously, he was a senior vice president at Photronics, where he was responsible for all aspects of the company’s IT infrastructure.

“George is an outstanding leader who has had an invaluable voice on the Photronics Board,” said CEO Frank Lee. “We are pleased that he will be spending more time on the execution of Photronics’ future direction and we expect to continue to benefit from his passion and leadership.”

“I am pleased to have my son George take on the role of Executive Chairman of the company,” said Deno Macricostas, who will remain a member of the Photronics Board of Directors. “His extensive business experience and knowledge of the photomask industry will help guide the company’s growth and operations into the future.”
