Lockheed Martin Emerges as Frontrunner in $3.5B Bid for Ultra Maritime

Lockheed Martin is the leading bidder to acquire Ultra Maritime, Advent International's undersea defense unit, in a deal valued around $3.5 billion. Talks are ongoing and no agreement has been finalized, though an announcement could come within days. Lockheed shares gained nearly 5% on the report.

LMT has emerged as the frontrunner to acquire Ultra Maritime, the undersea-warfare specialist owned by private equity firm Advent International, in a deal valued at roughly $3.5 billion. Talks remain ongoing and no agreement has been finalized, though reports suggest a public announcement could come as soon as next week.

Ultra Maritime, part of Advent's Cobham Ultra business, builds anti-submarine warfare technology including advanced sonobuoys used to detect submarines and torpedoes. Advent had explored a sale valuing the business at more than $4 billion, with JPMorgan and Guggenheim Partners advising, and other bidders remain in the auction process.

For Lockheed Martin, with a market capitalization near $110 billion, the price tag is material but manageable, and the deal would deepen its naval and undersea portfolio as Western navies re-prioritize anti-submarine capabilities. Lockheed shares gained nearly 5% on the report. Industry analysts are watching for a formal announcement, rival counterbids, and the shape of any antitrust review in an already consolidated defense sector.
