H-D Advanced Manufacturing Co. -- a partnership of The Riverside Co., Weinberg Capital Group and Hicks Equity Partners --  has sold Firstmark Corp., a North Carolina-based manufacturer of highly engineered components and subsystems for the aerospace and defense industries.

“Firstmark was a calculated addition to the H-D strategy, helping to further build the product line in our aerospace technology vertical offering highly engineered solutions for this industry,” Riverside Managing Partner Suzy Kriscunas said in a statement. “We are pleased that we were able to sell Firstmark to a buyer where it will be an even better strategic fit than it was under H-D.”

Houston-based H-D designs and manufactures “mission-critical,” hard-to-make components used in a wide range of applications, such as hydraulic actuation in airplanes, components for downhole mud motors for oil and gas applications and heavy-duty gears and gearboxes for a variety of industrial, construction and mineral extraction uses.

H-D acquired Firstmark in 2015 as a part of the H-D platform. The company manufactures aftermarket replacement products including mechanical, electromechanical and electronic components and subsystems, OEM aftermarket parts, safety restraints and leading-edge inflatable safety solutions used principally in legacy aerospace and defense platforms.

“We will deploy the resources from the Firstmark sale and continue to build H-D’s capabilities in its core aerospace and defense and industrial motion control end markets,” Riverside Partner Tim Gosline said.  “We’ll also continue to support organic growth and look for add-ons to accomplish this.”

  • Vice President Conner Harris.
  • Associate Charlie Cooper.
  • Operating Partner George Benson.
  • Riverside Partner Anne Hayes assisted with financing.
  • Origination Partner Jim Butterfield sourced the Firstmark deal.
