Austal Shares Soar 17% After Hanwha’s $1.2 Billion Takeover Bid For US Shipyard Operations

SYDNEY — Shares in Australian shipbuilder Austal Ltd surged more than 17% Tuesday after the company disclosed that South Korea’s Hanwha Group had offered to buy its United States operations for up to $1.2 billion, as the defense conglomerate looks to deepen its push into the American shipbuilding market.

The stock closed up 17.45% at $4.51, after touching an intraday high of $4.59, on volume of more than 10.3 million shares, giving the company a market capitalization of approximately $1.9 billion. The move marked Austal’s best intraday jump since mid-February and made it the top gainer on the benchmark ASX 200 index for the session.

Hanwha Defense USA offered to acquire Austal’s U.S. entities and operations for between $1.05 billion and $1.20 billion, according to the company’s disclosure. Austal’s board said the proposal deserved further evaluation and granted Hanwha a four-week due diligence period to firm up its offer, while cautioning there was no certainty the process would ultimately result in a completed deal.

Austal specifically noted that the proposal did not include any publicly traded shares in Austal itself, nor any of its core Australasian shipbuilding operations, meaning the company’s Australian defense manufacturing business and broader ASX-listed structure would remain intact regardless of the outcome of discussions over the U.S. unit. The company said its sovereign shipbuilding mandate and high-performing Australasian business would continue to generate value for shareholders independent of any transaction involving its American operations.

Hanwha already holds a substantial stake in Austal through a combination of direct share ownership and a cash-settled equity swap arrangement. Austal said Hanwha owns a 9.9% direct stake in the company alongside a swap arrangement covering a further 9.9%, effectively giving the South Korean group economic exposure to roughly one-fifth of Austal’s total shares outstanding. Hanwha increased its position from an initial 9.9% stake after receiving approval from Australian Treasurer Jim Chalmers in December 2025, following a review by the country’s Foreign Investment Review Board. That approval was granted subject to conditions governing Hanwha’s access to and storage of sensitive information, as well as restrictions on its board nominations.

Because the current proposal is centered on Austal’s U.S. operations rather than the parent company or its Australian assets, the potential transaction would not require scrutiny from Australia’s foreign investment regulator, according to reporting on the disclosure. Instead, the deal would need to clear a separate set of approvals from U.S. government agencies, given Austal’s extensive contracts with the U.S. Navy and the sensitive nature of its shipbuilding programs for the American military.

Alongside news of the offer, Austal disclosed that its U.S. business was expected to post an operating earnings loss of roughly 175 million Australian dollars for the 2026 financial year, reflecting higher losses on its shipbuilding programs. That would leave the broader Austal group with an operating loss of approximately 113 million Australian dollars for the year, compared with earnings of 113.4 million Australian dollars a year earlier. Despite those losses, the company said it retained a robust balance sheet, with cash at bank of 312 million Australian dollars as of June 30 and a net cash position of 185 million Australian dollars.

Hanwha’s offer follows its 2024 acquisition of the Philly Shipyard in Philadelphia, a deal that marked the South Korean conglomerate’s initial entry into U.S. commercial shipbuilding and signaled its broader ambitions to expand within the American defense manufacturing sector. A spokesman for Hanwha Defense USA said the company has made it a priority to significantly contribute to revitalizing American shipbuilding and is exploring a range of options to expand its footprint in the United States.

The offer for Austal’s U.S. unit comes as Australia pursues a broader military modernization push amid heightened tensions in the Indo-Pacific region, including concerns tied to Taiwan and the South China Sea, a backdrop that has drawn growing international interest toward Australian defense contractors and shipbuilders. Austal, considered Australia’s largest shipbuilder, designs and constructs vessels for both commercial and military customers, including long-running contracts to build littoral combat ships and other vessels for the U.S. Navy through its Alabama-based operations.

Austal is scheduled to release its full 2025-26 financial year results on August 29, a report that is likely to provide further detail on the performance of both its U.S. and Australasian operations as the due diligence period with Hanwha proceeds. Hanwha has not yet publicly commented further on the specifics of its offer beyond the initial disclosure.

With the four-week due diligence window now underway, investors are likely to watch closely for further updates on the negotiations in the coming weeks, particularly given the regulatory complexity involved in any transaction covering sensitive U.S. defense shipbuilding assets. Tuesday’s sharp share price reaction reflected significant investor optimism that a deal, if finalized, could unlock substantial value from Austal’s struggling U.S. operations, even as the company emphasized that its core Australian business would remain unaffected by the outcome.
