ManTech’s agreement to be acquired by the Carlyle Group in a $ 4.2 billion transaction began a week of private equity acquisitions in the public market.

Following the deal with ManTech, three other announcements were made for PE-supported companies adding to their business, including a start-up.

No conditions have been disclosed for these three transactions, but here are some other details.

Sigma defense systems

Backed by Sagewind Capital, the latest national security technology company focuses on the military’s communication environment and focuses on the so-called “JADC2” design.

Sub U Systems provides Sigma Defense with a broader portfolio of software-based solutions designed to help bring peripheral computing, artificial intelligence, machine learning and communication relay tools to the brink.

“The acquisition of Sub U is in line with our vision of autonomous connectivity of people, systems and data with an integrated hardware and software approach to communications,” Sigma Defense CEO Matt Jones said in a statement.

Sub U Systems was founded in 2008 and manufactures tactical routes, switches and computing technologies for commercial, government and military purposes. Founder and President Keir Tomaso will continue to monitor operations and lead the development of post-closure solutions.

Sagewind, based in New York, also supports government contractors Axient, By Light, Federal Advisory Partners and GCom.


DC Capital Partners not only acquires this defense technology company, but merges it with another of the investment intermediary’s portfolio businesses.

Founded in 2020, Hill Technical Solutions received support from DC Capital in the fall of 2020 to support the next phase of growth as a systems engineering and architecture firm. Valkyrie started in 2007 and today is a business with 700 employees, focused on system design and all phases of the life cycle after that.

The combination of Valkyrie and HTS introduces a company with a larger infrastructure to support C5I customer requirements – command, control, communications, computers, combat systems and intelligence.

“When Valkyrie was founded, our vision was and continues to be to quickly build a customer- and employee-focused company that provides quality support for our national priorities. We see this partnership as a continuation of this vision, “said Valkyrie CEO Gary Lisota in his release.

Chertoff Capital acted as Valkyrie’s financial adviser and Greenberg Traurig’s legal adviser. Arnold & Porter acted as legal advisor to DC Capital.

High Point Aerotechnologies

This brand new name, which is entering the fold, is just the beginning for Highlander Partners, a Dallas-based private investment company and the drone market in sight.

High Point is a holding company that the investor has advocated for, acquiring and merging companies that focus on developing technologies and systems that can withstand competitive unmanned aerial systems.

Jim Gavrilis joined High Point as president and CEO after a 24-year career as an army officer, followed by senior positions in the defense industry. He has also served as a Senior Adviser at the Center for Naval Analysis, the Johns Hopkins University Laboratory of Applied Physics and the Special Operations Command.

“With the right team and focused acquisitions, we have a significant opportunity to create a leadership position in the dynamic C-UAS market,” Gavrilis said in a statement. “We are in the process of recruiting experts on the subject to join the High Point team, and we intend to analyze both mature businesses and the development of potential acquisition technologies.”

“We were very focused on exploring the C-UAS arena,” added Highlander partner Ben Slater. “The industry is young, fragmented and has remarkable growth potential.”
