Austal’s Record High: Could Hanwha’s Stake Decision Change the Game for Defence Stocks?

Austal (ASX:ASB) has just delivered a financial performance that stunned the market. Its net profit surged by 503% in FY25, sending the ASB share price to a record high of around A$8.07 and cementing the shipbuilder’s reputation as one of the most strategically vital defence players in the region. Yet, as impressive as these numbers are, the bigger story may be what lies ahead. South Korea’s Hanwha Group is seeking to double its stake in Austal, a move that could reshape ownership dynamics and spark debates over sovereignty in Australia’s defence industry. Could this be the turning point, not only for Austal, but also for the broader sector of ASX-listed defence stocks?

What’s Driving the Rally?

The surge in Austal’s valuation comes down to its ability to consistently deliver on its US Navy contracts, which remain the backbone of its growth. For FY25, the shipbuilder reported a 503% increase in net profit compared to the previous year, driven by strong revenue growth from its aluminium warship programs and a robust pipeline of sustainment work in the United States.

The market reacted swiftly. Investors piled in, sending Austal shares soaring by around 20% to that ASB share price record high of A$8.07. Liquidity in the stock spiked, with volumes reflecting renewed institutional confidence. For a company long viewed as cyclical and dependent on contract wins, the magnitude of this result suggests that Austal has crossed into a new phase of earnings power.

But what’s behind this strength? The answer lies in Austal’s identity as a strategic shipbuilder. Its ability to win major contracts in both the US and Australian defence ecosystems positions it uniquely, particularly at a time when Western allies are prioritising naval capability under the AUKUS framework.

The Hanwha Chess Move

Hanwha’s move to nearly double its stake has introduced a new dynamic. The proposed jump from 9.9% to 19.9% positions Hanwha alongside Andrew Forrest’s Tattarang, which also holds a stake of nearly 19%. This would create two heavyweight shareholders with significant influence, but no outright control.

The US has already approved the proposal through its Committee on Foreign Investment in the United States (CFIUS), which is noteworthy given Austal’s contracts with the US Navy. That approval suggests Washington views Hanwha’s involvement as compatible with allied defence interests. The final hurdle lies with Australia’s Foreign Investment Review Board (FIRB), which must weigh the benefits of foreign capital and industrial partnerships against the risks of compromising Australia’s sovereign shipbuilding capabilities.

For investors, the chessboard looks intriguing. If Hanwha succeeds, Austal could gain not only capital but also access to Hanwha’s technological expertise in missile systems, defence electronics and land-based defence solutions. These synergies could strengthen Austal’s competitiveness in both domestic and export markets. On the other hand, increased foreign influence could raise concerns about governance, national security, and control of intellectual property.

Sovereign Defence Under Scrutiny

The debate over foreign ownership of a critical defence asset has sharpened. Austal founder John Rothwell and other industry voices have cautioned against allowing external shareholders too much influence over the company’s strategic direction. Their concern centres on protecting Australia’s sovereign shipbuilding capability and ensuring that sensitive intellectual property remains under national control.

To address these concerns, the government has introduced a so-called “poison pill” clause. This provision would trigger a public buyback if any shareholder’s stake exceeds 20%, effectively preventing a foreign entity from gaining controlling influence. It reflects the seriousness with which Canberra views Austal’s role in national security.

For investors, this adds another layer of complexity. On the one hand, the clause provides reassurance that ownership will remain balanced and sovereignty will be protected. On the other, it introduces an element of uncertainty around potential capital inflows and partnerships that could otherwise accelerate growth.

Why It Matters for Defence Stocks and Strategy

Austal is more than a listed company; it is a pillar of the $20 billion defence contract pipeline. Its projects underpin Australia’s contribution to the AUKUS alliance and ensure the Royal Australian Navy has the capacity to project power in the Indo-Pacific. In many ways, Austal has become a symbol of Canberra’s determination to maintain sovereign shipbuilding capability.

From an investor’s perspective, Austal’s significance stretches beyond its own balance sheet. Decisions made about Austal will shape the broader ASX defence ecosystem. If Hanwha’s bid is approved, it could signal a greater openness to cross-border collaboration in defence manufacturing. If rejected, it would highlight Australia’s intent to prioritise sovereignty over capital inflows, a stance that could affect other listed players such as Electro Optic Systems (EOS), DroneShield, and Codan.

Investors must therefore see Austal as a bellwether. Its trajectory will influence not only its own valuation but also sentiment across the sector.

Possible Scenarios Ahead

Scenario 1: Green Light for Hanwha

If FIRB approves the move, Hanwha could bring additional capital and technology expertise, potentially boosting Austal’s ability to scale globally. The Korean giant’s footprint in defence electronics and missile systems could complement Austal’s naval shipbuilding strengths. For investors, this scenario might support a continued re-rating of Austal shares as synergies are unlocked.

Scenario 2: Blockage to Protect Sovereignty

If the government blocks the stake increase, Austal remains firmly anchored in Australian hands. This would reassure stakeholders concerned about intellectual property leakage and reinforce the narrative of sovereign defence control. From a market perspective, this might limit some upside potential but provide long-term stability by aligning the company squarely with Canberra’s defence agenda.

Scenario 3: Partial Compromise

Another possibility is a middle ground, where Hanwha is allowed to expand its stake but is subject to strict conditions. This could include limits on board representation, safeguards around technology transfer, and commitments to maintain Australian jobs and facilities. Such an arrangement could provide Austal with resources while addressing sovereignty concerns.

Investor Takeaway

Austal’s record profit has already reshaped investor sentiment, but the Hanwha stake question adds a geopolitical overlay that few ASX companies ever face. For investors, the key variables to monitor are:

• The FIRB’s decision and the political signals it sends.
• The company’s ability to maintain its U.S. Navy pipeline while expanding local programs.
• The ongoing balance between capital inflows and sovereignty safeguards.

At this juncture, Austal represents both opportunity and hand risk. Its ASB share price record high reflects confidence in its operational momentum, but governance and ownership decisions will ultimately determine whether this becomes a sustainable growth story. For those with exposure to defence stocks, Austal is not just another shipbuilder; it is a bellwether for how Australia intends to navigate the intersection of capital markets, allied cooperation, and national security.

Conclusion

Austal stands at a historic crossroads. On one side, its financials and $20b defence contract pipeline reinforce its identity as Australia’s most important strategic shipbuilder. On the other, Hanwha’s ambition to double its stake has stirred debate about sovereignty, alliances, and the acceptable limits of foreign ownership in critical industries.

The outcome of this process could redefine the investment landscape for ASX defence stocks. Whether FIRB approves, imposes conditions, or blocks the move entirely, investors will need to recalibrate their expectations for Austal. What is certain is that the company’s record-breaking performance has placed it firmly on the radar, not just of markets, but of policymakers. For investors, that makes Austal one of the most compelling and closely watched, stories on the ASX in 2025.
