GHK Capital-Backed WSB Announces Acquisition of NEO Virtus Engineering

MINNEAPOLIS--(BUSINESS WIRE)--WSB LLC (“WSB”), one of the nation’s fastest growing infrastructure engineering and consulting firms, today announced the acquisition of NEO Virtus Engineering (“NEO Virtus” or the “Firm”), a specialized engineering consulting firm with deep expertise in photovoltaic (PV) and energy storage system design. This strategic addition strengthens WSB’s ability to support the full lifecycle of power/energy infrastructure for clients across the country. WSB is a portfolio company of GHK Capital Partners LP (“GHK”), a leading middle-market private equity firm based in Greenwich, CT.

“The acquisition of NEO Virtus Engineering marks a pivotal moment in WSB’s journey to build a national power/energy practice,” said Bret Weiss, WSB’s president and chief executive officer. “NEO Virtus’s technical excellence in PV, energy storage, and power system engineering perfectly complements our existing capabilities and allows us to deliver more comprehensive, future-focused solutions to our clients. Together, we’re expanding our services, empowering our teams, and positioning WSB as a leader in the power and energy space. I’m incredibly excited about what we’ll build together.”

NEO Virtus Engineering, founded in 2001 and headquartered in Littleton, Massachusetts, brings a highly skilled team with a reputation for collaboration, efficiency, and reliability—especially in navigating complex interconnection challenges in emerging solar markets. The Firm’s core services include PV and energy storage system design, owners engineering, power system studies, protection and control engineering, witness testing, and solar analytics.

“Joining WSB is an exciting step forward for NEO Virtus Engineering,” said Jim Bing, president of NEO Virtus. “We’ve always believed in engineering with purpose, and now we have the opportunity to scale that impact alongside a firm that shares our values and vision. This partnership gives our clients access to expanded services and deeper resources, while our staff gain new opportunities for growth, collaboration, and innovation. Together, we’re building something bigger—an energy practice that’s positioned to lead and evolve with the future.”

With the addition of NEO Virtus, WSB expands its technical bench and geographic reach, offering clients enhanced expertise in solar and energy storage, as well as robust operational support in human resources, marketing, project management, and IT. The integration will create new pathways for professional development and upward mobility for staff, while reinforcing WSB’s commitment to delivering elevated service and innovative solutions.

WSB and NEO Virtus will unify their market strategy as WSB in early 2026. This marks WSB’s sixth acquisition in two years and further expands WSB’s expertise across transportation, engineering, power, water resources, and construction management.
