Lockheed Martin has positioned itself as the leading contender to purchase Ultra Maritime, a specialized naval defense contractor currently held by private equity giant Advent International, in a transaction valued at approximately $3.5 billion, the Financial Times reports.
Lockheed Martin Corporation, LMT
Shares of LMT dropped over 1.4% in extended trading Wednesday following the report. The stock had gained 4.62% during the regular session, finishing at $545.91.
Ultra Maritime represents a strategic carve-out from Advent’s broader Cobham Ultra holdings — an enterprise Advent assembled through two significant United Kingdom transactions: the £4 billion privatization of Cobham in 2019 and the £2.6 billion purchase of Ultra Electronics in 2022.
The company specializes in submarine detection and anti-submarine warfare systems, manufacturing advanced sonobuoys capable of identifying torpedoes and underwater vessels. Its client roster includes the United States Navy and the United Kingdom’s Royal Navy.
Negotiations continue without a finalized agreement. People familiar with the matter told the FT that a public announcement could materialize during the week of July 7.
Advent International declined to provide comment. Lockheed Martin has not yet responded to inquiries.
Strategic Rationale
Lockheed’s existing Rotary and Mission Systems division already provides naval platforms with advanced sensors, sonar arrays, and integrated combat systems. Acquiring Ultra Maritime would significantly enhance its underwater warfare portfolio.
With a market capitalization hovering around $110 billion, a $3.5 billion acquisition represents a strategic bolt-on rather than a transformational mega-deal for Lockheed.
Multiple competing bidders remain engaged in the process. The FT emphasized that the sale process continues as a competitive auction, leaving open the possibility that a rival suitor could submit a superior proposal. The identities of alternative bidders have not been disclosed.
Regulatory Considerations
The proposed acquisition will likely encounter significant regulatory examination. Given Ultra Maritime’s British origins and its critical supply relationship with the Royal Navy, the transaction will probably require approval under the United Kingdom’s National Security and Investment Act.
U.S. review by the Committee on Foreign Investment (CFIUS) also appears probable considering the cross-border technology transfer and the sensitive nature of the defense applications.
The Financial Times report did not specify Lockheed’s planned financing approach for the acquisition. Lockheed has traditionally financed smaller acquisitions through a combination of debt issuance and available operating cash flow.
Shareholders will be seeking transparency regarding how a $3.5 billion capital allocation affects the company’s share repurchase program and dividend policy.
Bloomberg previously disclosed that Advent initiated the sale process for Ultra Maritime earlier this year.
