Part of the Company's 125th Anniversary Celebration and Continued Evolution into a Building Systems Solutions Firm

Limbach Holdings, Inc. (NASDAQ:LMB) ("Limbach" or the "Company"), a building systems solutions firm that partners with building owners and operators who have mission-critical mechanical, electrical, plumbing, and controls ("MEPC") systems, today announced that it will be relocating its corporate headquarters to Tampa, Florida, marking a milestone in the Company's 125th anniversary year.

Founded in 1901 in Pittsburgh, Pennsylvania, Limbach has spent more than a century delivering mechanical, electrical, plumbing, and control ("MEPC") systems for mission-critical facilities nationwide. While Tampa becomes the new corporate home, Limbach will maintain a strong presence in the Pittsburgh area, honoring its heritage.

The headquarters move aligns with the location of the majority of the Company's senior leadership and nearly 40% of its corporate workforce. Since establishing its Tampa office in 2020, the team has tripled in size, underscoring the city's growing talent pool. The establishment of the Tampa headquarters provides space for collaboration, innovation, and employee development.

"Our new headquarters reflects who we are today - aligned, collaborative, and committed to building on our legacy. As we formalize Tampa as our headquarters, we remain proud of our Pittsburgh roots and fully committed to growing our organic business in the region," said Mike McCann, President & CEO.

"We're thrilled that Limbach chose to move their corporate headquarters to Tampa," said Craig J. Richard, CEcD, President and CEO of the Tampa Bay Economic Development Council. "They've found the best talent and business climate to support their future growth objectives here, and we look forward to assisting them with further expansions in the years ahead."

Limbach will celebrate the new headquarters with a ribbon-cutting ceremony on March 11th, 2026, joined by the Tampa Bay Economic Development Council (EDC), a longstanding partner in the relocation. As part of the event, Limbach will present a donation to Feeding Tampa Bay, continuing its commitment to supporting the local community.
