He also serves as a Director of North America's largest battery industry event, The Battery Show, and is a special advisor to Pure Lithium, a Boston-based lithium metal battery technology company.

Mr. Kenneth Hoffman commented, "The world is looking for faster charging, less expensive, and higher density batteries. Being able to produce lower cost silicon anodes that enable faster charging and longer cycle life will be a key improvement in battery technology. I look forward to working with NEO as they look to solve these problems facing current silicon anodes."

Mr. Spencer Huh, President and Chief Executive Officer of NEO, stated, "We are greatly excited to invite Ken onto NEO's Board. Ken brings exceptional industry insight and strategic capabilities to the Company.
