Quantic Electronics this week said it has acquired BEI Precision Systems & Space Company, adding to its portfolio of defense electronics companies.

Terms of the deal were not disclosed. Quantic purchased BEI from the private equity firm J.F. Lehman & Co.

BEI, which is based in Arkansas, designs and manufactures resilient and reliable position feedback sensors and frequency reference technologies for space, land, air and sea applications.  The company’s products are used in military helicopters, fixed-wing aircraft and unmanned aircraft systems, combat vehicles, ground instruments, submarines and surface ships, satellites and other space platforms.

“This acquisition further establishes Quantic as a leading supplier of critical components for space, aerospace, and defense applications,” Kevin Perhamus, president and CEO of Quantic, said in a statement. “BEI Precision brings more than 60 years of experience designing and manufacturing proprietary optical encoders, scanners, accelerometers, and frequency products.”

Quantic’s financial adviser on the deal was Evercore and J.F. Lehman was advised by KippsDeSanto. Quantic is a portfolio company of the private equity firm Arcline Investment Management.

J.F. Lehman said that after acquiring BEI in 2017 it worked with the company’s management on two acquisitions, overhauled its research and development and business development functions, and optimized manufacturing operations. The result was “substantial revenue and earnings growth,” J.F. Lehman said.

“Our successful partnership with management has enabled BEI Precision to transform from a small, stable business unit of a larger corporate parent into a standalone, high-growth enterprise with state-of-the-art products occupying sole-source positions on high priority space and defense electronics programs,” Steve Brooks, BEI’s chairman and a partner at J.F. Lehman, said in a statement.

BEI has about 300 employees and Quantic, prior to the deal, about 600.
