Limbach (LMB) investor relations material

Business overview and differentiation

• Focuses on mission-critical facilities with mechanical, electrical, and plumbing services across the Northeast, Southeast, and Midwest regions, serving six key verticals including healthcare, industrial, manufacturing, data centers, life sciences, higher education, and culture/entertainment.

• Operates through two segments: Owner Direct Relationship (ODR) for existing buildings and General Contractor Relationships (GCR) for new construction, with a strategic shift toward ODR over the past four to five years.

• Differentiates through a connected geographic footprint, integrated solutions (design and installation), and a nimble, solutions-partner approach rather than a transactional contractor model.

• Emphasizes long-term customer relationships, aiming for multi-decade partnerships rather than one-off projects.

Market performance and strategy

• Healthcare remains the strongest vertical, but recent years saw spending delays across several sectors, prompting a focus on greater vertical market diversification.

• Bookings have rebounded, with $225 million in Q4 and $209 million in Q1, marking the strongest quarters in recent history and signaling momentum into 2026 and 2027.

• Sales process improvements and executive focus are credited for recent booking successes.

Data center expansion and risk management

• Data center work, especially in Columbus, Ohio, is expanding, leveraging existing relationships and a favorable supply-demand environment.

• Risk is managed by taking on projects of increasing size gradually, with a recent $30 million fabrication project and significant underutilized fabrication capacity in Chattanooga.

• Anticipates growth in retrofit and maintenance opportunities, especially with trends like liquid cooling, and is positioning for future maintenance contracts.

• Data center revenue mix includes both ODR and GCR, with a preference for direct owner contracts and a 20%-25% GCR share in current guidance.
