Tribus Aerospace Corporation acquires Precision Aerospace Corporation and Precision Micro Mill LLC


Tribus Aerospace LLC (“Tribus Aerospace”) announced today that an affiliate has completed the acquisitions of Precision Aerospace Corp. (“PAC”) and Precision Micro Mill LLC (“PMM”).  Tribus Aerospace is a precision machining business focused on critical engine, motion control and flow control parts and assemblies primarily for the aerospace and defense industries.  Shorehill Private Equity LP, the majority shareholder of Tribus Aerospace, supported the acquisition with additional equity capital.  William (“Bill”) R. Hoyer, President and sole owner of both PAC and PMM, will continue as President of both companies and will become a shareholder in Tribus Aerospace.


The terms of the acquisitions were not disclosed.


Founded in 1956 and acquired by Bill Hoyer in 1990, PAC is a Grand Rapids, Michigan-based manufacturer of complex parts and assemblies for a broad range of commercial aerospace and defense applications.  Products include hydraulic manifolds, port caps, mounting flanges, housings, rotor parts and assemblies used in hydraulic pumps, fuel systems, and transmissions.  PMM is a Wayland, Michigan-based captive contract manufacturer to PAC specializing in small volume, short lead time parts.


“I am grateful to our customers and associates at PAC and PMM who have helped us develop into a world-class manufacturer and believe that joining Tribus Aerospace will increase our ability to support and serve them,” said Bill Hoyer, President of PAC and PMM.


“The acquisitions of PAC and PMM fit precisely with our strategy to build Tribus Aerospace into a leading supplier of critical aircraft turbine engine, motion control and flow control components and assemblies,” said Scott Shedd, Co-Chairman of Tribus Aerospace.  “We are incredibly fortunate to have Bill lead our effort to build Tribus in the Midwest.  He is a proven leader with incomparable knowledge of our market,” added Simon Farhi, Co-Chairman of Tribus Aerospace.


“Bill has built an impressive business at PAC, with significant growth potential across a range of attractive commercial and military platforms.  We are excited to partner with Bill and his teams at PAC and PMM,” said Doug Knoch, Managing Director at Shorehill Capital.
