Larson Engineering Inc., a St. Louis-based engineering firm with Minnesota roots, has acquired Granite Falls-based Fagen Engineering LLC.

The acquisition comes as part of Larson’s ten-year strategic plan to achieve 25 percent growth revenue, according to a news release issued by Larson last week.

The two companies said they have a working relationship that extends more than two decades. The deal stems, in part, from Larson’s interest in Fagen’s “specialized ethanol and biofuel plant and carbon capture expertise,” the release stated.

“Through our 20-plus year relationship with Larson Engineering, we have seen the passion and teamwork they bring to projects,” said CEO of Fagen Engineering Terrin Torvik in the release. “We are excited to join this 100-percent employee-owned company, and we look forward to being a part of Larson’s innovative team in this next chapter.”

In an email to TCB, Larson Engineering Twin Cities regional manager Ethan Charpentier said his company sees potential in Fagen’s bioenergy and industrial engineering sectors.

“Fagen is the ethanol industry leading design builder and has been involved in more than 90 facilities, including original builds, expansions and enhancement projects,” Charpentier said.

Financial details regarding the transaction are confidential, Charpentier said.

Larson will take all of Fagen’s 11 current employees along with the company’s two locations: a headquarters in Granite Falls and another location in Greensville, South Carolina.

For its part, Larson has 45 employees in Minnesota and more than 170 employees nationwide. And though the company is now based in Missouri, Larson was first established in White Bear Lake back in 1974. In the years that followed, the firm went on to open offices in Illinois, Wisconsin, Arizona, and elsewhere. Larson opened a St. Cloud office in 2014.

A spokesperson from Larson said the acquisition will allow the company to take on “larger, more complex industrial projects across multiple sectors, including pulp and paper, and pharmaceutical manufacturing facilities.”

Added Charpentier: “With Fagen Engineering under our umbrella, we are best placed to capitalize on the growing demand in the bioenergy and industrial engineering sectors and help our clients in even more innovative ways.”
