(NASDAQ:LMB) ("Limbach" or the "Company"), a building systems solutions firm that partners with building owners and facilities managers who have mission-critical mechanical, electrical, and plumbing infrastructure, today announced the appointment of Nick Angerosa as Executive Vice President, National Customer Solutions, and Jay Sharp as Executive Vice President, Sales, effective January 13, 2026.

"These leadership appointments support Limbach's long-term growth strategy and reinforce the Company's vision to become an indispensable partner to building owners with mission-critical systems," said Mike McCann, President and Chief Executive Officer of Limbach. "We are excited about the progress we've made in building a proactive sales organization that positions Limbach as a trusted building solutions provider, delivering durable value for our customers. We plan to expand our data center and industrial and manufacturing verticals and believe these new leaders will accelerate our transition toward proactive, consultative partnerships as we grow our geographic footprint to serve national and local customers. Our objective is to deploy talent and capital where it generates the greatest risk adjusted returns."

The creation of a dedicated National Customer Solutions role formalizes Limbach's focus on national account opportunities. Angerosa will lead the strategy to support national owner-direct customers, leveraging Limbach's expertise, services, and resources to deliver consistent performance across key vertical markets. This role strengthens Limbach's ability to execute at the national account level by integrating service and product offerings, technical expertise, and operational insight to support customers where they operate. By centralizing accountability for national customers, the Company expects to improve consistency, and increase lifetime customer value.

Angerosa has been with the Company for more than 13 years, most recently as the President of the Southeast Region. He brings deep insight into the operational and technical complexities of the building systems industry and has played a key role in driving growth across the organization.

Sharp will be responsible for Limbach's overall sales strategy, sales enablement, and growth execution across the Company's footprint. His focus includes equipping teams with the tools, data, and insights needed to best support customers and their complex building systems. Mr. Sharp will provide critical leadership and support for the sales team across the Company, where he will ensure that selling resources are aligned with markets and verticals where returns are structurally higher, driving the long–term growth of the business.

Sharp brings 36 years of experience at Limbach, leading multiple regions through multiple market cycles, most recently as the President of the Midwest and Northeast Regions. Throughout his tenure, he has played a key role in shaping Limbach's customer-first sales approach, strengthening owner-direct relationships, and supporting disciplined, profitable growth. His role is intended to ensure that incremental sales investment is tied to measurable outcomes, including higher conversion rates, improved customer mix, and more predictable revenue streams.
