Mr. McConnell has nearly forty years of executive experience in the telecommunications sector, including approximately twenty years working for Sprint Corporation (now T-Mobile), where his positions included serving as the Chief Operating Officer and Executive Director of Operations for Sprint’s 4G business unit. Furthermore, Mr. McConnell has also served as Sprint’s Executive Director of Advanced Labs & Innovation, where he was responsible for research and development, systems and network design, engineering, product evaluation, customer trials, and quality certification for all wireless systems and products.

“I am excited to welcome Von, who has decades of experience working with cutting-edge technology, to Advent’s board of directors,” said Dr. Vasilis Gregoriou, Advent’s Chief Executive Officer and Chairman. “We look forward to leveraging his experience and relationships in two global telecommunications corporations as Advent looks to unlock the next step of its own growth.”

Mr. McConnell stated: “During my career, I have seen technology, specifically cell phones, emerge from the fringes of science fiction to mainstream adoption to being ubiquitous. I believe that Advent’s fuel cell technology has the same potential. Where clean, carbon-free energy seemed an impossible pursuit just a few years ago, Advent’s state-of-the-art, cutting-edge MEAs and fuel cells are ready to deliver on that promise as a mainstream solution to the world’s carbon crisis. I am honored to join the board and can’t wait to help Advent develop its IPCEI Green HiPo project and see it enter into long-lasting, mutually beneficial corporate partnerships deploying its fuel cells around the world.”

Mr. McConnell will assume the remainder of Katrina Fritz’s Class I term as director. Ms. Fritz resigned from the Advent board on May 27, 2022. Mr. McConnell qualifies as an independent director under the definition established in the NASDAQ listing rules.
