Lockheed Martin is reportedly leading the competition to acquire Ultra Maritime, the naval defense business owned by private equity firm Advent International, in a transaction that could value the company at approximately $3.5 billion, according to a Financial Times report citing people familiar with the negotiations.
Discussions are still underway, and the report said an agreement could be announced as early as next week if negotiations progress as expected. However, the sale process remains competitive, with several other interested bidders continuing to participate in the auction for the defense technology company.
Neither Advent International nor Lockheed Martin has officially confirmed the report. Advent declined to comment, while Lockheed Martin did not immediately respond to Reuters' request for comment.
Ultra Maritime is recognized for its advanced capabilities in anti-submarine warfare, undersea defense systems, and other naval military technologies. The company is part of Cobham Ultra, a defense group formed after Advent acquired British aerospace and defense company Cobham in 2019. Advent later expanded the business by combining it with Ultra Electronics following its 2022 acquisition, creating a stronger player in the global naval defense market.
The potential acquisition comes as major defense contractors continue to strengthen their portfolios in response to rising global security concerns. Ongoing conflicts, including the war in Ukraine and instability in the Middle East, have prompted governments worldwide to increase military spending, driving demand for advanced defense technologies such as submarine detection systems, sonar solutions, and maritime surveillance equipment.
For Lockheed Martin, acquiring Ultra Maritime would further expand its presence in the naval defense sector and enhance its portfolio of undersea warfare technologies, reinforcing its position as one of the world's leading defense contractors.
Investors showed little immediate reaction to the report, with Lockheed Martin shares edging slightly lower in extended trading. Market participants are expected to closely monitor developments over the coming days as the competitive bidding process continues and a potential agreement draws nearer.
