Exhibit 99.1


Willdan Announces CEO Succession


ANAHEIM, Calif.—(BUSINESS WIRE)—Willdan Group, Inc. (NASDAQ: WLDN) today announced that on December 8, 2023, Tom Brisbin, Willdan’s CEO, notified the Board of Directors (the “Board”) of his intention to retire from his position as CEO of the company effective December 29, 2023. Tom will retain his role as Chairman of the Board and will act as the company’s part-time consultant to ensure a smooth transition after December 29, 2023. Willdan’s President, Mike Bieber will succeed Tom as CEO and will become a Board Member effective as of December 30, 2023.


“I’d like to commend Tom for his leadership and commitment to our company over the past 16 years,” Mike Bieber commented. “I’m proud of what we’ve built at Willdan, and even more excited about where we’re headed. We are building a leading company that transitions communities to clean energy and a sustainable future. Willdan is finishing 2023 strong, and we’re well positioned for the next several years ahead. With just under $500 million in revenue this year and 1,600 team members, we are only getting started. I’d like to thank our customers and shareholders for their support, and I thank the Board for this opportunity.”


Tom has served as Willdan’s CEO since 2007, joining just after the company went public, and growing revenue more than six times over that period. During the 2008 financial crisis, he led the company’s expansion into energy efficiency, diversifying into a growing market and adding long-term financial stability. Tom has focused most of his career on developing a culture of organic growth and fostering leadership.


Mike and Tom met while working with one another 27 years ago. Mike joined Willdan in 2014 as Vice President, Corporate Development. For the last seven years, Mike has served as President and focused on company operations.


Willdan also announced that, in parallel with this transition, Kim Early, Willdan’s CFO, and Micah Chen, Willdan’s General Counsel, will each be promoted to Executive Vice President, effective December 30, 2023.
