Lockheed Martin Leads $3.5 Billion Bid for Ultra Maritime, Expanding Naval Capabilities

Lockheed Martin's shares dipped about 1.4% in after-hours trading after reports that it has emerged as the leading bidder for Ultra Maritime.
Ultra Maritime is part of Advent's Cobham Ultra portfolio, which was built through a 2019 £4 billion take-private of Cobham and a 2021 £2.6 billion Ultra Electronics acquisition; Ultra Maritime is described as one of the more technologically differentiated assets in that portfolio.
Lockheed Martin's current price-earnings ratio is 26.44x, signaling a premium valuation relative to historical levels.
There have been insider sales at Lockheed Martin in the past 12 months totaling about $3.83 million across two transactions.
Lockheed Martin's market capitalization is reported around $125.9 billion, underscoring the deal's scale within its vast defense portfolio.
Lockheed Martin has emerged as the frontrunner to buy Ultra Maritime, a naval defense specialist, for roughly $3.5 billion, according to Financial Times. An announcement could come as early as next week. The deal would be one of the biggest defense acquisitions of the year.
Lockheed's shares dipped about 1.4% in after-hours trading after the news broke, according to TradingView. The world's largest defense contractor has a market cap of around $125.9 billion, so a $3.5 billion deal would be a significant but manageable move.
Ultra Maritime is part of Advent International's Cobham Ultra portfolio. It makes anti-submarine warfare technology — tools used to find and track enemy submarines. That includes torpedo systems and sonobuoys, which are floating devices dropped into the ocean to detect submarines below the surface.
Its customers include the U.S. Navy and the British Royal Navy. That makes the sale politically sensitive. Both governments will likely want a say in who ends up owning this technology. Yahoo Finance described Ultra Maritime as one of the more technologically distinct assets in the Cobham Ultra portfolio.
Advent International built Cobham Ultra through two large acquisitions. First, it took Cobham private in 2019 for £4 billion. Then in 2021, it bought Ultra Electronics for £2.6 billion. Ultra Maritime was carved out from that combined business as a standalone naval defense unit.
Now Advent is running a competitive auction to sell it. Multiple bidders joined the race, according to Financial Times. Lockheed has pulled ahead, but the deal is not final. Negotiations are still ongoing.
Lockheed Martin already dominates aerospace and missile defense. Buying Ultra Maritime would push it deeper into undersea warfare — a fast-growing priority for the U.S. and its allies. China's submarine fleet has expanded rapidly, and NATO navies are spending more to counter it.
Adding torpedo systems and submarine-detection tools would give Lockheed a stronger hand when bidding for future naval contracts. The company's current price-to-earnings ratio sits at 26.44x, a premium level that signals investors expect growth. An acquisition like this could help justify that valuation.
Lockheed insiders sold about $3.83 million worth of stock in the past 12 months across two transactions, according to Yahoo Finance. That is a small amount relative to the company's $125.9 billion market cap, but worth noting as the deal talks heat up.
The after-hours dip suggests some investors are cautious about the price tag. A $3.5 billion deal adds to Lockheed's cost base at a time when defense budgets are under political pressure. Markets will be watching closely for an official announcement next week.
