Aurizon's Rail Network Holds the Value While Coal Haulage Tests Investors

Fund managers broadly agree the regulated network is undervalued, but recontracting losses in coal haulage and softer FY27 guidance have split them on whether the market discount is a bargain or a warning.

Two businesses, one share price

The investment debate over Aurizon comes down to how investors weigh two very different businesses. One is a regulated rail network in central Queensland that managers describe as irreplaceable infrastructure. The other is above-rail coal haulage, which faces contract losses and recontracting risk. In October, ClearBridge Investments pointed to resilience in the regulated assets, noting that “Higher bond yields can feed into regulatory settings and allowed returns, with regulatory pricing resets expected over 2027 providing the potential for higher net cash flows.”

Merlon Capital Partners added to its position in September on the view that the market is pricing Aurizon's highly valuable regulated assets at too steep a discount. Maple-Brown Abbott struck a similar note even as its position detracted, saying network earnings are resilient and valuations remain supportive.

The network at the core

L1 Capital has been the most consistent advocate for the network's value. In a June presentation, L1 said around 60 per cent of its valuation is underpinned by the regulated rail network, which it views as one of the few large-scale listed transport infrastructure assets in Australia. L1's Hawkins said in March that Aurizon is the stock he would be most comfortable owning for the next five years, explaining: “I want a company that has a moat to its earnings and it's not going to be decimated by AI in the next five years”.

Certainty has improved. L1 highlighted a proposed 10-year extension to Aurizon's regulatory arrangements with miners for access to the Queensland network, subject to approval by the Queensland Competition Authority, which it said enhances long-term earnings and cash flow certainty. Pendal Group noted in February that Aurizon decided to retain 100 per cent of the network after its strategic review, meaning no transaction will crystallise the value managers see. Wentworth Williamson had earlier said it would advocate strongly for surplus capital to be returned to shareholders if asset sales proceeded.

Where coal haulage bites

The bear case centres on coal haulage contracts. Perpetual Asset Management rated the stock a sell in March, noting about 50 per cent of above-rail coal contracted volumes are up for expiry over the next two years in a competitive environment, and that “even if they do retain all of those volumes, there's a risk that you see the margin come under pressure as those contracts roll through.” Perpetual cited Whitehaven's expected benefit from a new contract as evidence of that pressure, and questioned whether the One Rail bulk acquisition will earn an adequate return.

The August result appeared to bear this out. Pendal said FY27 guidance disappointed as coal customers reset contracted volumes lower, implying close to no earnings growth, with consensus estimates cut by around 8 per cent. Dividend guidance missed expectations and no buyback was announced, which Pendal read as evidence the company is running low on debt capacity for capital management. Ralton Asset Management said the dividend miss weighed heavily on income-focused investors, and Maple-Brown Abbott cited recent contract losses and risk from further renewals.

Bulk growth and capital returns

Beyond coal, L1 sees optionality in the bulk business, including the contract to rail product from BHP's Olympic Dam, which it described as strategically significant given BHP's ambition to grow the operation beyond 2030, and nearby resource projects including Arafura's Nolans Bore rare earths project. L1 also expects improvement in the containerised freight business as volumes grow, service frequency rises and the QAL terminal in Perth is completed. With growth capex falling, L1 believes improving free cash flow should underpin sustained dividends, and welcomed the increase in the payout ratio to 90 per cent of underlying profit.

Positioning reflects the split

Positioning has been mixed. Allan Gray sold in April after concerns about the bulk business abated, redeploying capital into more contrarian ideas, and Wentworth Williamson fully exited with a strong gain. Investors Mutual Limited trimmed into strength twice, Ellerston Capital took profits after the February result, and Argo Investments used the stock as a funding source while saying it sees nothing wrong with the business. Quest Asset Partners covered a profitable short in August. On the other side, Merlon added, Milford Asset Management participated in a new corporate bond issue from Aurizon Network, and PM Capital invested in Aurizon Network at yields it put at around 6.1 to 6.3 per cent.

What managers are watching next

The key markers are Queensland Competition Authority approval of the 10-year network agreement, the outcome of coal haulage recontracting, and the 2027 regulatory pricing resets that ClearBridge expects could lift network cash flows. Managers will also watch whether falling capex delivers the free cash flow improvement L1 anticipates, and whether Aurizon regains room for buybacks after the August result left none on the table.
