Fortescue’s (ASX.FMG) fiscal fourth-quarter shipments of 52 million metric tons are down 5% from the prior fourth quarter, but shipments for the year are up 1%. Cost inflation and lower volumes meant unit cash costs rose 19% in the quarter, to USD 19.40 per metric ton, while problems at Iron Bridge persist.

Why it matters: Fiscal 2026 shipments and unit costs are broadly in line with our forecasts. However, guidance for fiscal 2027 shipments is lower, and for unit cash costs and capital expenditure, is higher, than we expected, likely why shares have since fallen 5%.

  • Our estimate for hematite volumes at around 190 million metric tons is modestly lowered, but we raise expected hematite unit costs by 1% to around USD 21 per metric ton, the midpoint of USD 20.50-USD 21.75 guidance. We also now expect higher capital expenditure in the coming years.
  • We lower forecast Iron Bridge production by 22% to 8.6 million metric tons (its share) in line with updated guidance for it to reach capacity later than expected. Forecast total shipments for fiscal 2027 are modestly down to about 200 million, near the guidance midpoint, from around 205 million.

The bottom line: We reduce our fair value for no-moat Fortescue by 4% to $15.50, driven by lower near-term sales volumes, higher life of mine unit cash costs for Iron Bridge, and increased capital expenditure.

  • Despite recent declines, shares trade 16% above our intrinsic assessment, likely due to the market expecting strong iron ore prices of around USD 100 per metric ton to continue for longer than we do.
  • We see prices moderating over the longer term to our assumed midcycle price of about USD 75 per metric ton from 2030, based on our estimate for the long-run marginal cost of production. We expect Chinese steel production to soften and seaborne iron ore supply to rise, led by Simandou and Vale.

Fortescue’s fair value lowered by 4% due to Iron Bridge Problems and increased capital expenditure

Fortescue is the world’s fourth-largest iron ore exporter. Margins are well below industry leaders BHP and Rio Tinto, and some way behind Vale, meaning Fortescue sits in the second half of the cost curve, at around the 75th percentile. This is a primary driver of our no-moat rating. Lower margins primarily result from price discounts from selling a lower-grade (57% to 58% iron) product compared with the 61% iron ore benchmark. The lower grade is effectively a cost for customers through a greater proportion of waste to transport and process, additional energy/coal per unit of steel and lower blast furnace productivity. This results in a lower realized price versus the benchmark. In the 10 years ended June 2025, the company realized an approximate 22% discount versus the then 62% benchmark.

It increased production rapidly thanks to favorable iron ore prices, aggressive expansion, and historically low interest rates. Expansion from 55 million metric tons of capacity in fiscal 2012 to around 170 million by fiscal 2016 is unprecedented. It built much of its capacity around the China boom peak and baked in a higher capital base than peers. This means returns are likely to lag the industry leaders who benefited from building significant capacity when the capital cost per unit of output was lower.

It has done an admirable job of reducing cash costs materially versus peers, helped by further expansion in recent years. However, product discounts remain a competitive disadvantage. The addition of 22 million metric tons a year of production from the 69%-owned Iron Bridge joint venture gives it options to blend. Iron Bridge grades are much higher, around 67%, meaning Fortescue could blend most of its iron ore to increase its average grade to between 58% and 59%.

It is a China fixed-asset investment play, with practically all of its iron ore sold there. In the long term, we see demand for steel in China declining as the country’s stock of infrastructure matures and with the rate of urbanization past its peak.

Its strategy is to transform into a diversified iron ore, copper, and clean energy company. Its non-iron ore initiatives are at an early stage, but it has big ambitions.

Bulls say

  • Fortescue provides strong leverage to the Chinese economy. If growth in steel consumption remains strong, it’s also likely iron ore prices and volumes will, too.
  • Fortescue is the largest pure-play iron ore company in the world and offers strong leverage to emerging world growth.
  • When steel industry margins contract, it’s likely that product discounts narrow significantly relative to historical averages, reducing Fortescue’s competitive disadvantage relative to the majors.

Bears say

  • We think that ultimately Chinese fixed-asset investment will slow, and future iron ore volume growth and prices are likely to be much less favorable.
  • Margins are significantly lower than those of diversified peers BHP, Rio Tinto, and Vale, and this could see Fortescue’s margins fall much more than peers if iron ore prices fall.
  • Fortescue produces an inferior, lower-iron-grade product, which attracts a discount to the benchmark 61% iron ore fines price. Lower-grade reserves mean this discount is likely to persist.
