Lockheed Martin to buy Ultra Maritime for $3.45 billion in ASW push

Lockheed Martin's $3.45 billion acquisition of Ultra Maritime marks the latest consolidation in the defense sector as navies race to modernize anti-submarine warfare capabilities.

Lockheed Martin agreed to buy Ultra Maritime for $3.45 billion on Monday, adding sonar and torpedo defense systems to its portfolio as allied navies accelerate spending on undersea warfare technology.

"Undersea superiority belongs to those who move fastest and work together best," said Stephanie C. Hill, president of Lockheed Martin Rotary and Mission Systems. "By joining forces with Ultra Maritime, we're accelerating our commitment to deliver the most advanced undersea and anti-submarine warfare capabilities to our U.S. and allied partners across the globe."

The all-cash transaction values Ultra Maritime at roughly 2.7 percent of Lockheed Martin's $125.6 billion market capitalization. Ultra Maritime, which Advent International acquired in 2022, develops sonobuoys, towed sonar arrays, hull-mounted sonar systems, and autonomous maritime sensing platforms for allied naval forces. Citi served as financial adviser to Lockheed Martin, with Hogan Lovells Cadwalader providing legal counsel and Fried Frank advising on tax.

The deal reflects a broader push by defense contractors to consolidate niche maritime technology providers as China's naval expansion and undersea infrastructure investments drive demand for anti-submarine warfare systems. Lockheed Martin expects the transaction to close in the second half of 2026, subject to regulatory approvals.

Ultra Maritime's Turnaround Under Advent

When Advent International invested in Ultra Maritime in 2022, the business had mission-critical technology but had been underinvested and was not yet fully delivering for customers, said Shonnel Malani, managing partner at Advent and chair of the board at Ultra Electronics. Over four years, Advent strengthened Ultra Maritime's industrial capacity and developed next-generation autonomous solutions. The sale price reflects that turnaround, with Advent exiting at a premium to its 2022 entry.

What the Deal Means for Defense Investors

Lockheed Martin shares traded at $544.75 on Monday, near the midpoint of their 52-week range of $410.11 to $692.00. The stock carries a price-to-earnings ratio of 26.38 and offers a dividend yield of 2.5 percent. The acquisition expands Lockheed Martin's addressable market in maritime defense, a segment where allied governments are increasing budgets amid rising undersea threats from state actors. Ultra Maritime's exportable product lines — particularly its sonobuoys and towed sonar arrays — give Lockheed Martin a broader platform to compete for international naval contracts that historically went to European defense primes.
