Stanmore Posts $174 Million EBITDA as Wet Weather Bites

Stanmore Resources reported underlying EBITDA of $174 million for the first half of 2026 on its H1 earnings call, while advancing its Eagle Downs and Lancewood metallurgical coal projects through wet weather and softer macroeconomic conditions.

Stanmore Resources Ltd (OTC: STMRF) told investors on its first-half 2026 earnings call that underlying EBITDA came in at $174 million, a result the Queensland-focused metallurgical coal producer delivered while wet weather disrupted mining and a softer macroeconomic backdrop weighed on steelmaking demand. The company also used the call to mark progress on two development assets, Eagle Downs and Lancewood, that will shape its production profile well beyond this year.

The market reaction on the company's thinly traded American over-the-counter line was not kind. STMRF last changed hands at 1.73, down 9.99% from the prior close of 1.92, with the shares finishing at the bottom of a day range that began and ended at the same level — a sign of how little depth the US quote carries. That close was recorded as of 20:00 GMT on Friday, 21 August 2026, and the market is shut. On the same day the broad American benchmarks moved the other way: the S&P 500 tracker closed at $765.72, up 0.41%, the Nasdaq 100 proxy at $713.44, up 0.35%, and the Dow tracker at $532.22, up 0.89%.

What underlying EBITDA does and does not tell you

Underlying EBITDA — earnings before interest, tax, depreciation and amortisation, stripped of items management deems one-off — is the number coal producers lean on because it isolates the cash-generating capacity of the mines from the accounting noise of a capital-heavy business. At $174 million for the half, it is the single figure Stanmore chose to anchor the call around, and it is the one against which the market will judge the cost programme the company says it is running.

What EBITDA does not capture is exactly what matters most for a producer in the middle of a build cycle: the cash going out the door on development. Depreciation is added back, interest is added back, and sustaining and growth capital are not deducted at all. For a company simultaneously funding Eagle Downs and Lancewood, the distance between reported EBITDA and free cash flow is where the real story sits. Investors listening to the call would have been watching capital commitments as closely as the headline earnings line.

Eagle Downs and Lancewood as the output story

Both projects sit in Queensland's Bowen Basin, the source of much of the world's seaborne hard coking coal — the grade steelmakers feed into blast furnaces, distinct from thermal coal burned for power. Metallurgical coal pricing is cyclical and tied to steel production rather than electricity demand, which means Stanmore's revenue moves with global construction and manufacturing activity rather than with weather-driven power loads.

Advancing two development assets at once during a period the company itself describes as carrying macroeconomic headwinds is a deliberate bet on the medium term. The logic is familiar in mining: build through the soft part of the cycle so tonnes arrive when prices recover. The risk is equally familiar — capital is committed against a price deck nobody controls, and a longer-than-expected downturn turns a growth pipeline into a balance-sheet strain. Stanmore's management flagged both projects as progressing, which is the language of schedule adherence rather than acceleration.

Rain is a production variable, not an excuse

Wet weather is a structural feature of Bowen Basin mining, not an anomaly. Heavy rainfall floods pits, softens haul roads, cuts truck cycle times and forces dewatering before overburden removal can restart. The effect flows straight through to unit costs: fixed costs are spread over fewer tonnes, so cost per tonne rises even when nothing about the operating plan has changed. That is the mechanism behind the cost-management emphasis Stanmore struck alongside the earnings figure, as reported by GuruFocus.

The distinction worth holding onto is between tonnes lost and tonnes deferred. Rain-affected volume that can be recovered later in the year hurts a half-year print without damaging the annual outcome. Volume genuinely lost to a washed-out pit does not come back. The company did not quantify the split, and it is not something an outside observer can reconstruct from the earnings figure alone.

The US listing is a poor read on the business

The 9.99% single-day decline in STMRF looks dramatic, but the mechanics deserve a caveat. An over-the-counter American quote on a company whose primary listing and liquidity sit elsewhere tends to trade in wide, infrequent increments. A day range that opens and closes at 1.73 with no intraday variation suggests very few prints. Reading a percentage move off that quote as a considered market verdict on $174 million of EBITDA overstates what the tape can support.

That does not make the move meaningless — it simply means the signal is weaker than the number implies, and that anyone tracking Stanmore's valuation should be watching the primary listing rather than the American shadow quote. It also puts the divergence from the US benchmarks in context: STMRF fell on a day when all three major American index trackers finished higher, but the company's operating exposure is to seaborne coking coal prices and Chinese and Indian steel output, not to the drivers moving the S&P 500.

What to watch from here

Three things will determine whether the first-half figure marks a floor or a step down. First, whether second-half volumes recover the ground lost to rain, which will show up in unit costs before it shows up in revenue. Second, the capital profile at Eagle Downs and Lancewood — how much is committed, over what period, and whether either schedule shifts. Third, the direction of metallurgical coal pricing, which Stanmore does not control and which will swamp most of what management can do on costs.

The cost-management framing on the call is the tell. Producers emphasise costs when they expect revenue to do the heavy lifting for a while yet. Delivering $174 million in a half described as weather-hit and macro-pressured is a workmanlike outcome; whether it looks strong or thin in retrospect depends entirely on where coking coal prices go while two new mines are being built.

Frequently asked questions

What did Stanmore Resources report for the first half of 2026?

Stanmore Resources reported underlying EBITDA of $174 million for the first half of 2026 on its H1 earnings call. Management framed the result around cost management, noting that wet weather disrupted operations and that broader macroeconomic conditions created headwinds. The company also confirmed continued progress on its Eagle Downs and Lancewood development projects during the period.

What are Eagle Downs and Lancewood?

Eagle Downs and Lancewood are the two development projects Stanmore Resources highlighted as advancing on its first-half 2026 earnings call. Both sit within the company's Queensland metallurgical coal portfolio in Australia's Bowen Basin region. They represent the medium-term output story for the business, though Stanmore did not publicly attach specific capital figures or production timelines to them in the earnings call summary.

Why did STMRF shares fall 9.99%?

STMRF last closed at 1.73, down 9.99% from a prior close of 1.92, as of 20:00 GMT on 21 August 2026. The day range opened and closed at the same 1.73 level, indicating very few trades. STMRF is an American over-the-counter quote for a company whose main liquidity sits on its primary listing, so single-day percentage moves can be exaggerated.

What is underlying EBITDA and why do miners use it?

Underlying EBITDA is earnings before interest, tax, depreciation and amortisation, adjusted to remove items management considers one-off. Mining companies favour it because it isolates cash generated by operations from the accounting effects of a capital-intensive asset base. Its weakness is that it excludes capital spending entirely, so it can look healthy while a company is consuming cash on new mine construction.

How does wet weather affect coal mining costs?

Heavy rain floods open pits, degrades haul roads and slows truck cycles, forcing dewatering before overburden removal can resume. Because a large share of mining costs are fixed, spreading them over fewer tonnes pushes unit cost per tonne higher even when the operating plan is unchanged. Some rain-affected volume is deferred and recoverable later; some is permanently lost.

What is metallurgical coal and how does it differ from thermal coal?

Metallurgical coal, also called coking coal, is fed into blast furnaces to make steel. Thermal coal is burned to generate electricity. The two trade at different prices and respond to different demand drivers: metallurgical coal tracks global steel production, construction and manufacturing activity, while thermal coal follows power demand. Stanmore's Queensland operations are focused on the metallurgical grade.
