In a bid to accelerate its manufacturing processes to meet well-reported client demand, Tesla has acquired Minnesota-based Perbix Machine Co Inc., a former partner, and manufacturer of automation systems.

Perbix is long-known to Tesla, serving as one of its machine suppliers for the past three years. One key responsibility has focused on the automation of drive-unit rotor production for Tesla’s vehicles, along with other equipment at Tesla’s Gigafactory, its Nevada battery manufacturing facility.

The terms of the deal, including purchase price, have yet to be disclosed. However, payment is believed to be a combination of cash and Tesla shares with roughly $10.5 million in stock, or the equivalent of approximately 34,770 shares using today’s stock price, due to James S. Dudley, Perbix’ owner, according to an SEC filing.

Currently, Perbix comprises a team of around 150 employees, working out of manufacturing, design, and engineering facilities in Brooklyn Park, Minnesota. Tesla has not indicated the transfer of any employees from Perbix’ Minnesota location. According to its Linkedin profile, Perbix was founded in 1976 with a focus on “comprehensive manufacturing and engineering services including complete design and fabrication of automation systems, build-to-print equipment, custom machining of components, and contract manufacturing services.”

With ongoing production bottlenecks for its Model 3, subsequently postponed product launches, and a backlog of roughly 500,000 orders, Tesla has made many moves to increase its production and supply capacity. In addition to building an internal team dedicated to factory automation, it has made several acquisitions.

Last year, it acquired Grohman Engineering for $135 million, a German engineering firm specializing in automated manufacturing systems, later spun off into the Tesla Advanced Automation group. Before that, Tesla acquired Riviera Tool and SolarCity, a tool and die producer and clean-energy company, respectively. It even failed an acquisition with a $325 million deal gone awry for Simbol Materials, a lithium extraction startup that valued itself at a $1.6 million valuation, poorly matched to Tesla’s only offer of $325 million before the deal fell apart.
