Rio Tinto shares (ASX: RIO) are down 3.72% today at A$172.75, as markets work through the news that the majority-owned Tomago aluminium smelter will receive A$2.5 billion in combined federal and state government support to remain operational amid crippling energy costs.
Why Are Rio Tinto Shares Down?
The Tomago aluminium smelter in New South Wales, which consumes roughly 10-15% of the state’s electricity supply, secured the decade-long support package after warning that its viability was under threat when its current power supply contract expires later this decade. Rio Tinto owns slightly more than 50% of the facility, with Gove Aluminium Finance and Norsk Hydro holding the remaining stakes.
Electricity accounts for more than 40% of Tomago’s operating costs, making it acutely vulnerable to Australia’s surging power prices. The support package is structured to help the smelter transition to renewable energy sources while installing flexibility upgrades that will allow the facility to reduce power consumption during periods of high grid demand, effectively functioning as a large-scale demand response asset.
The venture partners will contribute A$1.1 billion toward plant upgrades, with the government funds spread over approximately ten years to underpin long-term renewable power purchase agreements and grid-service capabilities. The arrangement follows a similar A$2 billion support package announced in March 2026 for Rio’s Boyne smelter in Queensland, establishing a pattern of government intervention to preserve Australia’s energy-intensive aluminium industry.
Political and Public Backlash
The bailout has drawn sharp criticism from taxpayer advocacy groups and opposition politicians, who point out that Rio Tinto reported net profits between A$10 billion and A$17 billion in recent years. Public sentiment, reflected in Australian online forums and social media, has questioned why profitable multinational corporations require taxpayer support to maintain operations, with some commentators arguing the government should have demanded equity stakes in exchange for the funding.

The optics are particularly challenging for Rio given its recent history of seeking government assistance for its Australian aluminium operations. The company’s 2024 annual report explicitly acknowledged that government support would be necessary to maintain the competitiveness of its energy-intensive smelting assets in the face of structural power market changes.
From Rio’s perspective, the deal aligns with its broader decarbonisation strategy and ambitions to produce low-carbon aluminium that can command premium pricing from customers focused on reducing Scope 3 emissions. The company has already signed power purchase agreements for 2.2 gigawatts of renewable energy capacity at its Gladstone operations and views the transition of its Australian smelters to clean power as essential to maintaining social licence and market positioning.
Government officials have framed the support as an investment in critical manufacturing capacity for the energy transition, noting that aluminium is essential for transmission infrastructure, electric vehicles, solar panels, and wind turbines. The argument positions Tomago as strategically important beyond pure commercial metrics, though this has done little to assuage concerns about corporate welfare.
What Lay Ahead
The company’s recent half-year and production update was broadly reassuring. Iron ore sales volumes were solid, copper and lithium output continued to ramp, and full-year guidance across key commodities was reaffirmed. Progress at Oyu Tolgoi and in the lithium portfolio added to the execution confidence. That backdrop has not changed, but strong operational delivery can only carry a stock so far when valuation starts to stretch and the macro mood turns cautious.
Adding to the pressure, RBC moved to a sell-equivalent rating on Rio’s shares, citing expectations of further weakness in iron ore prices and limited upside following the recent share price gains. That kind of broker call does not always move the stock directly, but it reinforces a narrative that has been building, that the easy money from the rally may have already been made, and the risk-reward is less compelling at current levels. The Street’s consensus price target of A$168.63 sits approximately 2.8% below today’s last price, which does not help.
Price Targets
On the charts, the medium-term structure remains intact. The stock is still trading above its 50-day moving average, which itself sits well above the 200-day average. That alignment suggests the trend has not broken, and the pullback is occurring from a firm base. The RIO share price currently sits around a support zone that previously held in April, and July, before breaking down.
The Tomago removes near-term closure risk and preserves earnings from a strategic asset, but it also reinforces uncomfortable truths about the structural challenges facing Australian aluminium production and the company’s dependence on government largesse to maintain operations that were once profitable on their own merits.
