Alcoa Corporation (AA) Cash Flow Statement

The wide swings in OCF/NI, from -0.42 in 2026Q1 to 14.35 in 2024Q2, suggest that net income is not a reliable proxy for cash generation on a quarterly basis. The 2026Q2 OCF/NI of 1.49 is more moderate, but the historical volatility implies that working capital changes and other non-cash items heavily influence reported cash flows. Investors should monitor the sustainability of cash conversion, as the gap between net income and operating cash flow appears driven by timing of working capital rather than fundamental profitability.

The FCF trajectory shows a sharp recovery in 2026Q2, driven by a surge in operating cash flow to $608M, which more than offset capex of $186M. However, the prior quarter's negative FCF of -$298M highlights the lumpiness of cash generation, likely tied to aluminum price movements and working capital swings. The 10.6% FCF margin in 2026Q2 is the highest in the trailing ten quarters, suggesting that if sustained, Alcoa could be entering a period of stronger cash generation, but the volatility warrants caution.

Capex has remained relatively steady, ranging from 2.8% to 7.0% of revenue, with no dramatic increases despite revenue growth. This suggests that Alcoa is managing capital expenditures conservatively, likely prioritizing maintenance capex over aggressive expansion. The stable capex/revenue ratio, combined with rising revenue, implies that Alcoa is generating incremental cash flow without a proportional increase in capital spending, which could support higher FCF if revenue remains elevated.

The large swings in working capital changes, particularly the -$795M in 2026Q1 and +$495M in 2025Q4, suggest that Alcoa's operating cash flow is heavily influenced by timing of receivables, inventory, and payables. The 2026Q2 negative working capital change of -$184M partially offset strong net income, but the overall trend indicates that Alcoa may be managing its working capital cycle actively, possibly to align with aluminum price cycles. Investors should monitor whether these swings are seasonal or indicative of structural inefficiencies.

Dividends have been consistent at around $26M per quarter, indicating a stable commitment to shareholder returns. However, buybacks were only executed in 2025Q3 and Q4, totaling $84M and -$84M (net), which may indicate opportunistic repurchases rather than a systematic program. The lack of buybacks in 2026 suggests that Alcoa is prioritizing cash retention or debt reduction, possibly to strengthen its balance sheet given the cyclical nature of aluminum prices.

The cumulative OCF of $2.24B versus cumulative net income of $2.05B suggests that Alcoa has generated more cash than its accounting earnings, which is a positive signal for earnings quality. However, this is partly due to non-cash charges like D&A and favorable working capital movements in certain quarters. The divergence is not extreme, but it implies that Alcoa's earnings are backed by real cash flows, though the quarterly volatility in OCF/NI warrants ongoing scrutiny.
