Konica Minolta’s $1 billion purchase of Ambry Genetics, which closed today, was shepherded by West L.A.’s Intrepid Investment Bankers, company officials announced.

The investment bank served as the exclusive financial advisor to the Aliso Viejo-based biotech firm in its sale to the Japanese digital technology giant.

Konica Minolta Healthcare Americas Inc. and Innovation Network Corp. of Japan paid $800 million to shareholders of the privately held Orange County company, with another $200 million to be paid over the next two years if certain benchmarks are met. The deal, in which Innovation Network has a 40 percent stake, was announced in July.

Ambry Genetics, an 18-year-old genetics testing company will continue to operate under the Ambry name. It has about 700 employees.

Intrepid, founded 35 years ago, provides merger-and-acquisition, capital raising and strategic advisory services to middle-market companies with revenues between $20 million and $1 billion. It was listed by the Business Journal in April as the fourth largest investment bank in Los Angeles, based on its 23 employees.
