Rio Tinto Group (RIO) Income Statement

The 14.5% YoY growth in 2026Q2 is the strongest since 2021Q4, suggesting a cyclical upturn, but the trajectory is uneven with prior quarters showing near-flat or negative growth. This volatility reflects the company's exposure to spot commodity pricing, particularly iron ore, and the absence of recurring revenue streams. Investors should monitor whether this growth is sustainable given China's property sector weakness and potential supply additions from Simandou.

The margin decline reflects lower commodity prices and rising input costs, particularly energy and labor. However, Rio Tinto's cost curve advantage in Pilbara iron ore appears to provide a floor, as margins have stabilized around 25-28% in recent quarters. The aluminium segment remains a drag due to electricity costs, but the shift to renewable energy could improve margins over time. Compared to peers, Rio Tinto's gross margin is lower than BHP's 82.2% but higher than Vale's 34.4%, reflecting its diversified portfolio.

The high fixed-cost structure means that small revenue changes lead to outsized operating income movements. For instance, a 10% revenue decline in 2022Q2 led to a 41% drop in operating income. This leverage cuts both ways, as the recent 14.5% revenue growth in 2026Q2 drove a 45.5% EPS increase. SG&A appears well-controlled, with recent quarters showing minimal SG&A, suggesting cost discipline, but the lack of R&D in most quarters may indicate underinvestment in future growth.

The increase in COGS reflects inflationary pressures on energy, labor, and maintenance, particularly in the aluminium and minerals segments. While SG&A has been kept low, the lack of R&D spending in most quarters may indicate a focus on cost reduction over innovation. The company's ability to manage costs will be critical, especially as it invests in growth projects like Simandou and Oyu Tolgoi, which could increase depreciation and operating expenses.

The inflection was driven by record iron ore prices and strong demand, but the subsequent normalization highlights the cyclicality of the business. The company's ability to maintain margins above 25% during the trough suggests structural resilience, but the peak margins are unlikely to return without a similar demand shock. The current recovery in 2026Q2 may indicate a new cycle, but investors should be cautious about extrapolating recent growth.
