Dalrymple Bay Infrastructure Limited

The Business

Dalrymple Bay Terminal is the sole coal export facility serving its section of the Bowen Basin, Queensland's premier metallurgical coal region. Rail infrastructure physically locks roughly 20 producer customers to this single terminal: there is no competing facility they can switch to. Revenue is not won in a marketplace, it is calculated by formula. A regulated per-tonne charge, escalated by inflation and adjusted for capital spending, is applied to 84.2 million tonnes of contracted annual capacity. Customers pay whether or not they ship the coal.

Recent Performance

The stock has traded in a narrow band over the past year, consistent with a bond-like security rather than a growth story. First-half results confirmed the terminal charge stepped up as scheduled, with the per-tonne rate rising from $3.72 to $4.02 at the start of the new contract year, an 8.1% increase off a base that itself grew roughly 5% the year before. Earnings have tracked guidance closely, with no surprises in either direction.

Outlook

The next two years carry the strongest growth in the forecast. A committed $300 million capital upgrade lands in mid-2027, lifting the terminal charge by roughly $0.53 per tonne and driving a step-change in revenue growth over FY27 and FY28 well above the underlying trend. After that, growth is expected to normalise to around inflation alone once the capital-driven uplift is fully absorbed. Margins should stay structurally high near 95% throughout, since almost all operating costs are passed through to customers rather than absorbed.

Key Risks

Structural decline in steel-making demand for metallurgical coal, as electric-arc furnace technology gains share, could strand terminal value over the long run if seaborne demand from India and South East Asia fails to grow as expected. A first-ever pricing renegotiation in 2031 carries no precedent: the terminal's monopoly position offers some negotiating leverage, but there is no track record to anchor expectations, and an adverse outcome could compress growth for several years. Political pressure for heavier-handed economic regulation is a smaller, lower-probability risk, though it would also weigh on the pricing formula that underpins the entire cash flow stream.

What to Watch

• Jul 2027 NECAP capital upgrade commissioning — the thesis-defining event, confirming whether the $300m spend delivers the guided per-tonne charge uplift on schedule.
• 2-4 years New capital investment series approved — would extend growth beyond the currently committed projects.
• 5 years 2031 pricing renegotiation signals — early customer engagement will hint at whether the monopoly position translates into negotiating leverage.

Company Description

Dalrymple Bay Infrastructure owns and operates the Dalrymple Bay Terminal, a coal export facility in Queensland with contracted capacity of 84.2 million tonnes a year. The business has a single operating asset and a single revenue line: a regulated terminal infrastructure charge levied on every tonne of contracted capacity, regardless of whether that coal is actually shipped. There are no other divisions, no diversification by commodity or geography. Around 10 producer customers, mostly Bowen Basin metallurgical coal miners, are contracted under take-or-pay arrangements that run to 2031, with the top three customers accounting for roughly 62% of revenue.

Where the Growth Is

The near-term growth driver is a committed $300 million capital investment program (NECAP) landing in mid-2027. It lifts the regulated terminal charge by approximately $0.53 per tonne, adding an estimated $45 million of annual revenue once commissioned. This drives an elevated, above-trend revenue growth rate through FY27 and FY28 before growth settles back to inflation-only levels. Whether further capital series get approved beyond what is currently committed is the main swing factor for the growth outlook over the next two to four years.

Competitive Position

The terminal's competitive position is about as strong as regulated infrastructure gets. Rail lines physically connect the contracted mines to this one terminal, and building a rival facility would require years of approvals plus capital that no producer group has signalled any intention to commit. Market share is effectively fixed at 100% of its catchment by definition; there is no competitor to lose share to. The durability of this position runs well beyond a decade, underpinned by physical rail lock-in, the regulatory framework governing terminal pricing, and contracts that extend to 2031. The one advantage that erodes over time isn't competitive, it's the underlying demand for metallurgical coal itself as steelmaking technology evolves.

Management & Capital Discipline

Management has delivered its capital program on time and on budget, and has diversified its funding base with a $350 million note issuance at a point when doing so made sense given prevailing rates. Roughly 65-75% of operating cash flow is paid out as distributions each year, with the remainder funding regulated capital works and gradual debt reduction. Disclosure on management's own share ownership and how their pay is structured is thinner than at comparable regulated infrastructure peers, which makes it harder to independently verify how well management's interests are aligned with shareholders, even though the delivery track record itself has been solid.

Financial Position

Net debt sits at roughly 6.7 times earnings before interest, tax, depreciation and amortisation, high by ordinary corporate standards but typical for regulated infrastructure with contracted, inflation-linked cash flows. The debt service coverage ratio (a measure of how many times over cash flow covers debt repayments) sits at 2.6 times against a covenant floor of around 1.4 times, providing a meaningful buffer. Credit ratings sit at investment grade with a stable outlook. Revenue would need to fall by roughly a third before covenant pressure became a real concern, a scenario the fully contracted revenue base makes unlikely outside a structural collapse in coal demand.
