Morgan Stanley-backed Alliance Technical completed the acquisition of four environmental laboratories, including Summit Environmental Technologies, Fremont Analytical, Orange Coast Analytical and CHESTER LabNet. Financial terms were not disclosed. "The laboratory acquisitions are a significant adjacency for Alliance. We originated as a regional stack testing company, but we've made tremendous strides over the last few years to expand our geographic footprint and service offerings to include LDAR, CEMS, environmental consulting, and software. These acquisitions also represent an expansion beyond air testing into different media including water, hazardous waste, and soil," Premal Vora, Alliance Technical Chief Strategy Officer.
