Rio Tinto Group (RIO) Cash Flow Statement

The consistent OCF/NI ratio above 1.0 suggests that non-cash charges like depreciation and amortization (ranging from $2.4B to $4.1B) are providing a buffer, but the gap between net income and operating cash flow is not widening alarmingly. However, working capital changes have been volatile, with a notable -$1.6B outflow in 2026Q2, which may indicate timing effects in receivables or inventory. Investors should monitor whether this conversion quality persists if commodity prices soften.

The trajectory shows a clear step-down from the super-cycle peak, with FCF margins now hovering in the 8-11% range, similar to 2024 levels. This suggests that the company is operating in a more normalized pricing environment, and the recent 7.7% revenue growth has not translated into proportional FCF expansion due to higher capex. The gap between net income and FCF is widening, as capex has increased from $3.1B in 2022Q2 to $5.9B in 2026Q2, indicating a strategic shift toward growth investments.

The rising capex/revenue ratio suggests that Rio Tinto is in a phase of elevated investment, which may be aimed at expanding copper and high-grade iron ore capacity. This is a departure from the maintenance-heavy capex of earlier periods, and it implies that near-term FCF will be constrained. The depreciation and amortization charges have also grown steadily, from $2.4B to $4.1B, which may indicate that the asset base is expanding, but investors should assess whether these investments will generate adequate returns given the cyclicality of commodity prices.

The volatility in working capital changes, ranging from -$927M to +$392M, indicates that the company's cash conversion is sensitive to the timing of receivables and inventory, particularly in the Pilbara where shipment schedules can shift. The negative working capital in 2026Q2 may reflect a build-up in inventory or slower collections, which could be a temporary phenomenon. However, if this persists, it could signal weakening demand or operational inefficiencies, warranting close monitoring.

The company's commitment to shareholder returns is evident, but the dividend payout has often surpassed FCF, forcing reliance on cash reserves or debt. For instance, in 2022Q2, dividends were $7.6B against FCF of $7.4B, and in 2021Q4, dividends were $9.1B against FCF of $8.5B. This suggests that the dividend policy is not fully covered by FCF, which could be a concern if commodity prices decline further. The absence of buybacks in the data indicates that dividends are the primary return mechanism, and the sustainability of this payout will depend on the success of growth projects.

The cumulative gap between net income and FCF is substantial, driven by $46.9B in total capex over the period. This indicates that while earnings are strong, the company is reinvesting a large portion of its cash flow into growth initiatives, which may limit distributable cash. The divergence is not a sign of poor earnings quality, but rather a reflection of the capital-intensive nature of the mining industry. Investors should assess whether these investments will generate future cash flows that justify the current payout levels.
