Aurizon Holdings Limited

The Business

Aurizon runs three businesses under one roof. The Network division operates the Central Queensland Coal Network (CQCN), the only rail corridor connecting Queensland's Bowen Basin coal mines to export ports. It earns regulated returns on a $6.2 billion Regulated Asset Base (RAB), which is the value of infrastructure assets the regulator allows the company to earn a return on. The Coal division hauls coal over that network and others, controlling roughly 60% of Australia's coal rail volumes under contracts averaging 5-10 years. The Bulk division hauls everything else, from iron ore to grain, and is the primary growth engine following a major BHP contract win.

Recent Performance

FY25 delivered revenue of $3,952 million, up 2.8% on the prior year's $3,844 million. EBITDA (earnings before interest, tax, depreciation and amortisation) fell 3.0% to $1,576 million as a fuel cost timing lag and one-off restructuring charges compressed margins from 42.2% to 39.9%. Earnings per share declined 12% to 19.5 cents. The share price has tracked sideways around $3.80-$4.10 over the past twelve months, reflecting investor uncertainty about the coal transition timeline.

Outlook

Management has guided FY26 EBITDA to $1,680-1,750 million, implying a recovery toward 41% margins as the $60 million cost-out programme flows through. We forecast revenue growing at 3-4% annually through FY28, driven by Network RAB expansion, CPI escalation on coal contracts, and the BHP bulk haulage ramp. EBITDA margins should peak near 42% in FY28 when the UT5+ regulatory reset takes effect, before gradually compressing as carbon and labour costs accumulate. Net profit should reach $504 million by FY27, up 45% from the FY25 trough.

Key Risks

The dominant risk is conceptual, not operational: whether the market is correct to apply a discount rate more consistent with a coal industrial than a regulated infrastructure business. If the higher rate is warranted, the investment case narrows considerably. A structural decline in metallurgical coal demand would strip $150 million or more from EBITDA. Adverse modification of the UT5+ regulatory terms could reduce the expected Network uplift by $30 million annually and remove the primary re-rating catalyst.

What to Watch

The thesis-defining event is the Queensland Competition Authority's draft decision on UT5+ in the second half of 2026, which will determine whether the CQCN's access pricing framework supports the infrastructure re-rating that Aurizon's fundamentals justify.

• H2 CY2026 QCA UT5+ Draft Decision — Approval as submitted would add $45 million per year to Network EBITDA from FY28 and crystallise the infrastructure narrative. 68% customer support is unprecedented for an access undertaking.
• FY27-FY28 BHP Bulk Contract Ramp — Full ramp adds $70-100 million in incremental Bulk EBITDA, diluting coal concentration and supporting a higher valuation multiple.

Company Description

Aurizon Holdings is Australia's largest rail freight operator, structured around three divisions. The Network division (36% of revenue, 61% of EBITDA) owns and operates the CQCN under a 99-year lease from the Queensland government, earning regulated returns for providing track access to coal producers. The Coal division (45% of revenue, 33% of EBITDA) hauls coal from mine to port across Queensland and New South Wales, operating under long-term take-or-pay contracts with miners. The Bulk division (28% of revenue, 11% of EBITDA) hauls non-coal commodities including iron ore, grain, alumina, and increasingly copper, anchored by a major BHP contract secured in 2024. A small "Other" segment houses residual container operations and corporate costs, running at a loss that is narrowing as container operations wind down.

Where the Growth Is

The Bulk division is the growth engine. It contributed $169 million of EBITDA in FY25, roughly 11% of the group total, but is accelerating at approximately 8% annually as BHP's copper haulage contract ramps through FY27-28. We estimate $70-100 million of incremental Bulk EBITDA over the next three years. This matters beyond the raw earnings contribution: every dollar of Bulk profit dilutes Aurizon's coal concentration, which is the primary reason the market applies a discount to the stock. By FY28, Bulk should represent 14-15% of group EBITDA, up from 11% today. The segment also provides a template for winning critical minerals haulage as new mines develop in Queensland.

Competitive Position

The CQCN lease is the centrepiece. It grants Aurizon exclusive control of the only rail corridor connecting Bowen Basin mines to export terminals at Gladstone, Hay Point, and Abbot Point. There is no alternative route, no competing rail line, and no realistic prospect of one being built given the $15-20 billion replacement cost and regulatory barriers. The lease runs until 2109. In coal haulage, Aurizon holds approximately 60% market share in a duopoly with Pacific National (owned by Brookfield). Switching rail operators requires 12-18 months of fleet repositioning, creating meaningful switching costs. Contracts averaging 5-10 years with CPI escalation clauses provide revenue visibility well beyond typical industrial businesses. The current contract book covers 229 million tonnes. These advantages are deeply entrenched and unlikely to erode within a decade, barring a structural collapse in Queensland coal demand.

Management & Capital Discipline

CEO Andrew Harding has delivered on near-term commitments. The $60 million cost-out programme was completed in full. The UT5+ regulatory submission secured 68% customer support, an unusually high level for an access undertaking where customers typically oppose higher charges. The BHP bulk contract win was a strategic milestone. In FY25, management returned $550 million to shareholders through dividends and buybacks. Capital expenditure remains disciplined at $710 million, split between $600 million of maintenance and $110 million of growth investment. One honest observation: management's repeated assertion of "long-term growth in coal" deserves scepticism. They have a structural incentive to maintain this narrative given the CQCN's coal dependency, and the thermal coal trajectory clearly contradicts it. The investment case does not require coal growth, only stability in metallurgical coal, and investors should not rely on management's more optimistic framing.

Financial Position

Net debt sits at $5.25 billion, representing 3.3 times EBITDA. For a regulated infrastructure business with predictable cash flows, this leverage is within normal operating parameters. Aurizon has structured its debt through a "split" framework that ring-fences Network borrowings (backed by the regulated asset base) from the operating divisions, reducing contagion risk. Ninety-one percent of debt is hedged against interest rate movements. Operating cash flow converts at 93% of EBITDA, which is strong for a capital-intensive business. The balance sheet can comfortably weather a cyclical downturn, though leverage above 4.0 times would warrant concern given the coal exposure.
