Naprotek, an Edgewater Capital Partners Portfolio Company, Acquires SemiGen

Oct 26, 2021

Naprotek, LLC has completed the acquisition of SemiGen, Inc., a privately held company based in Londonderry, NH. This increases Naprotek’s capabilities to include advanced RF/Microwave products, assembly, and test services and expands its reach across the United States.

Founded in 2009, SemiGen provides products and services to the RF/Microwave community across markets including Defense, SATCOM, Space, and Advanced Communications. Their products include passive and active semiconductor components ranging from attenuators, capacitors, diodes, filters, and resistors to complex thin film circuits. Their manufacturing services span from RF/Microwave and PCB assembly to performance testing and in-house ion beam foundry. 

“We are excited to expand Naprotek’s capabilities and geographical reach with highly engineered products and services from SemiGen,” said Daniel Everitt, President and CEO of Naprotek. “SemiGen brings deep technical expertise in RF/Microwave technologies, aligning perfectly with Naprotek’s core offering, and the sum of our teams is truly greater than its parts. Our customers may now leverage full-service offerings across RF/Microwave microelectronics, SMT, hybrid assembly, and semiconductor products. This is a very important step in our growth strategy and was meaningfully informed by our customers’ feedback and technology roadmaps.”

Tim Filteau, President of SemiGen, commented, “I'm excited to work with the Naprotek team and to continue to lead SemiGen. Together Naprotek and SemiGen offer a unique combination of technical skills, products, manufacturing services, and technology solutions. This acquisition will enhance growth and enable innovation for our customers.”

Naprotek, which was acquired by Edgewater Capital Partners in December 2020, is strategically growing its capabilities in high-quality, technically differentiated electronic technology solutions to better serve its customers and their high-reliability applications. Naprotek’s sophisticated and rapid engineering change management process, commitment to quality, and personalized customer service are essential elements when time-to-market is critical.

“We are thrilled to welcome SemiGen and its team into the Naprotek platform and broader Edgewater portfolio of companies. We plan to continue to add additional differentiated technology capabilities to the Naprotek platform to better service our customers within the high-reliability markets,” commented Pete Ostergard, Partner with Edgewater.
