Defense industry heavyweight Lockheed Martin has emerged as the leading candidate to purchase Ultra Maritime, a naval technology firm currently held by private equity group Advent International, in a transaction potentially valued at approximately $3.5 billion, the Financial Times has disclosed.
Lockheed Martin Corporation, LMT
Shares of LMT tumbled over 1.4% in post-market activity Wednesday following the disclosure. The stock had gained 4.62% during the regular session, finishing at $545.91.
Ultra Maritime represents a carved-out division from Advent’s broader Cobham Ultra holdings — an enterprise assembled through two significant United Kingdom transactions: the £4 billion privatization of Cobham completed in 2019 and the £2.6 billion takeover of Ultra Electronics finalized in 2022.
The business specializes in anti-submarine warfare solutions, manufacturing sophisticated buoys engineered to identify torpedoes and underwater vessels. Key clients include the United States Navy and the Royal Navy of the United Kingdom.
Negotiations remain active, with no binding commitment yet established. People familiar with the matter told the FT that a public announcement might materialize as soon as the week commencing July 7.
Advent International refused to provide commentary. Lockheed Martin has not yet replied to media inquiries seeking comment.
Strategic Rationale
Lockheed’s Rotary and Mission Systems division currently provides naval forces with advanced sensor packages, sonar equipment, and integrated combat platforms. Acquiring Ultra Maritime’s capabilities would strengthen that underwater combat portfolio considerably.
With a market capitalization hovering around $110 billion, a $3.5 billion acquisition represents a digestible transaction for Lockheed — strategic and focused rather than company-transforming.
Additional suitors remain engaged in the competitive process. The Financial Times indicated the sale continues as an active auction, suggesting a competitor could potentially submit a superior proposal. The identities of alternative bidders have not been disclosed publicly.
Regulatory Considerations
The proposed transaction will likely encounter a multifaceted regulatory approval process. Given Ultra Maritime’s British origins and its supply relationship with the Royal Navy, the deal will probably face examination under Britain’s National Security and Investment Act framework.
Review by the Committee on Foreign Investment in the United States (CFIUS) also appears probable considering the international dimensions of the technology and its defense customer relationships.
The Financial Times report did not specify Lockheed’s intended financing structure for the acquisition. Lockheed has typically funded smaller acquisitions through combinations of debt issuance and generated operating cash.
Shareholders will seek detailed information regarding how a $3.5 billion capital deployment might affect the company’s share repurchase program and dividend policy.
Bloomberg previously disclosed that Advent initiated the sale process for Ultra Maritime earlier in the current year.
