Dalrymple Bay Infrastructure (ASX:DBI): Reaping In Revenue From The Largest Coking Coal Export Terminal

Dalrymple Bay Infrastructure (ASX:DBI) is often misunderstood. It is not a coal company and it does not behave like one. It is a regulated, inflation‑linked toll road for coal exports, collecting fees whether or not a tonne moves across the wharf. In a year defined by geopolitical shocks and volatile commodity markets, that distinction has become more valuable.

The share price has already moved, rising roughly nearly 40% over the past twelve months, yet the investment case for further growth remains intact. Interest costs are rising, net profit has softened and China demand always sits in the background, but the underlying business continues to do what it was designed to do: generate stable, contracted cash flow.

Dalrymple Bay Infrastructure’s Secret Sauce Of Success

DBI listed on the ASX in December 2020 after being carved out of Brookfield Infrastructure Partners. Its sole asset is the long‑term lease and operating rights to the Dalrymple Bay Terminal, the world’s largest metallurgical coal export terminal by capacity, located at Hay Point in Queensland. The terminal serves the Bowen Basin, one of the most important coking coal regions globally.

The operating model is deliberately simple. Producers contract throughput capacity on long‑duration, take‑or‑pay agreements. DBI earns a Terminal Infrastructure Charge (TIC) regardless of whether the contracted tonnes are shipped. The TIC is regulated by the Queensland Competition Authority and indexed to CPI, which embeds inflation protection directly into revenue. The terminal is fully contracted through to 2028. This combination of regulated pricing, CPI linkage and take‑or‑pay structure is the core of the investment thesis. It is why DBI trades more like a bond‑proxy infrastructure asset than a commodity‑exposed operator.

2025: A Year That Looked Exactly as It Should, From Several Perspectives

DBI’s 2025 results, released in February 2026, were broadly consistent with what investors should want from a regulated infrastructure asset. Revenue rose 10.6% to A$849.81m, driven by CPI‑linked TIC increases and ancillary revenue. EBITDA grew 5.2% to A$294.3m. Funds from Operations, the more relevant measure for distribution sustainability, increased 10.6% to A$173.3m (excluding one‑offs). Management lifted 2026 distribution guidance by 7.7% to 26.375c per security, signalling confidence in the asset’s cash‑generation profile.

Net income fell sharply to A$29.26m, but the decline reflects higher depreciation and financing charges tied to the Northern Expansion Capital Allowance Projects. These are growth investments that expand terminal capacity and are recovered through future TIC adjustments. For income‑focused investors, the FFO line remains the more instructive indicator.

The first half of 2025 had already hinted at the pattern, depicting EBITDA up 5.3%, NPAT up 17%, net debt‑to‑EBITDA falling from near 9x to roughly 6x and its investment‑grade ratings were reaffirmed by S&P and Fitch. The balance sheet is not without leverage, but it is moving in the right direction.

From a share price perspective, DBI has been one of the stronger performers in the ASX infrastructure cohort. The stock reached an all‑time high of A$5.58 on 24 February 2026, the day results were released, before easing back to around A$4.91. Volatility remains low, consistent with a beta in the 0.28–0.43 range. Analyst consensus sits near A$5.50, implying around 12% upside, with a Buy rating across covering brokers. The forward yield is close to 5%, which remains competitive given the inflation‑linked distribution growth.

The Iran Conflict: Noise for Some, Support for Others

The conflict that began on 28 February 2026 with US‑Israeli strikes on Iran and the subsequent closure of the Strait of Hormuz has unsettled commodity markets. For DBI, the implications are indirect but broadly supportive. We know that coal prices rose, but higher energy costs across mining and transport have mitigated any windfall.

But the key point is that DBI’s revenue does not depend on coal prices. The TIC is fixed, regulated and contracted. Higher coal prices may help customers’ economics and support contract renewals, but they do not flow through DBI’s revenue line. What matters is throughput continuity, and there is no plausible scenario in which Bowen Basin exports to Japan, South Korea or India are disrupted by a conflict centred on the Persian Gulf.

The Middle East consumes only around 3m tonnes of metallurgical coke per year, and Iran’s coking coal is domestically sourced. DBI’s customer base is geographically insulated. The conflict has even removed two Iranian steel plants from the global market, modestly supporting demand for Australian steelmaking coal.
Freight costs and war‑risk insurance premiums are rising, which is worth monitoring, but DBI’s take‑or‑pay structure means the terminal charge accrues even if shipments are delayed.

Outlook: A Clear Path with One Notable Headwind

DBI enters the second half of 2026 with several supportive factors. Distribution guidance is locked in. NECAP projects are progressing and will add capacity and TIC recovery. The geopolitical backdrop, while unsettling, reinforces the scarcity value of stable, inflation‑linked Australian infrastructure assets. The A$1.07bn refinancing completed in late 2025 reduced interest costs and extended debt maturity, giving the balance sheet more breathing room.

The main headwind is the roll‑off of lower‑cost interest rate swaps from mid‑2026. Management expects interest costs to rise to around 6.5%, which will pressure net profit and free cash flow. FFO, however, remains supported by non‑cash depreciation and the regulated revenue base.

Consensus for the next financial year is ~$75m profit, or $0.21 EPS, implying a forward PE of roughly 22–23x. It is not a cheap multiple, but scarcity value rarely is. Investors are paying for a globally significant, regulated, inflation‑linked asset with a track record of distribution growth.

Conclusion

DBI is not a growth story. It is a capital‑preservation, income‑compounding asset built for investors who understand the difference between a coal miner and a coal toll road. The business continues to perform as intended: revenue and FFO rising, distributions increasing, leverage trending lower and regulatory frameworks providing predictability. The Iran conflict does not threaten DBI’s contracted revenue base and may even support the economics of its key customers.

With a Buy‑rated consensus, a yield near 5% and CPI‑linked growth embedded in the contract structure, DBI remains a credible core holding for income‑oriented Australian portfolios.
