Australia's largest shipbuilder has confirmed preliminary talks with a little-known Florida group, raising the prospect of a contest for its prized Alabama shipyard just as South Korea's Hanwha moves toward a binding offer.

A takeover tussle is brewing over the most strategically sensitive asset in Australia's defence-industrial base. Austal (ASX:ASB), the country's biggest shipbuilder, has confirmed it held preliminary discussions with Florida-based Wildcat Infrastructure about a potential transaction — a disclosure that injects a fresh rival into what had looked like a clear run for South Korea's Hanwha to buy Austal's US operations. Austal shares firmed on the news, rising about 1.2 per cent to $4.47.

The company was careful with its language. "Austal has held preliminary discussions with Wildcat Infrastructure regarding a potential transaction, but no formal offer has been received," it told the market. In takeover terms that is an important distinction: talks are not a bid, and investors should treat Wildcat's interest as an emerging possibility rather than a competing offer on the table.

What Hanwha has proposed

Hanwha remains the front-runner. Through its US Subsidiary Hanwha Defence USA, the conglomerate has tabled an indicative, cash proposal valuing Austal's American arm at roughly US$1.05 billion to US$1.2 billion — around A$1.5 billion to A$1.7 billion — on an enterprise basis, with no financing conditions. Austal's board has granted Hanwha a period of exclusive Due Diligence to firm the approach into a binding offer, and chief executive Paddy Gregg has described the proposal as a "major development" carrying "great momentum."

The structure matters. Rather than pursue the whole company, Hanwha has targeted only Austal USA — the Mobile, Alabama shipyard that builds vessels for the US Navy and Coast Guard and generates roughly two-thirds of group revenue. That Carve-Out would leave Austal's Australian and Asian yards, and its Strategic Shipbuilding Agreement with the Commonwealth, in local hands. Hanwha already owns 19.9 per cent of Austal, having built the stake on-market with Australian regulatory clearance, and says US authorities cleared it in June 2025 to acquire up to 100 per cent of the American business.

This is Hanwha's second tilt. In 2024, Hanwha Ocean pursued the entire company at $2.825 a share before abandoning the effort amid difficulties securing due diligence and uncertainty over US national-security clearance.

The Wildcat wildcard

Wildcat Infrastructure is far less known. Led by Eric Nicolaides, the group has interests spanning the United States, India and South Korea. According to reporting in The West Australian, Wildcat is expected to unveil its own proposal within days, positioning itself as an American alternative to Hanwha — and there is speculation it could seek Austal's Australian and Asian facilities as well as the US yard. Wildcat declined to comment when contacted.

The appeal of a domestic US owner is not hard to see. Any change of control at Austal USA requires approval from Washington, including the Committee on Foreign Investment in the United States, the Defense Counterintelligence and Security Agency and antitrust review. While the current US administration has been receptive to South Korean investment in American shipbuilding, some observers suggest regulators may be more comfortable with a US buyer taking ownership of a yard so central to naval programs.

What it means for shareholders

For Austal investors, competitive tension is the friend of value — but nothing is settled. Hanwha has momentum, a defined price and a head start in due diligence; Wildcat has, so far, only talks and the strategic logic of American ownership. A binding Hanwha offer could arrive before Wildcat formalises anything, and the board has said it will assess any binding proposal on its merits and in the interests of shareholders and other stakeholders. Investors will be watching whether a genuine contest materialises, and how far regulators in Canberra and Washington are prepared to let it run.
