Exxon Mobil Corporation (XOM) Cash Flow Statement

The OCF/NI ratio ranged from 1.14 in 2024Q2 to 2.08 in 2026Q1, showing that cash generation is not only stable but often amplified relative to reported earnings. The persistent positive gap is largely attributable to substantial D&A (averaging $6.5B per quarter) and working capital swings, which are typical for capital-intensive integrated oil companies. This suggests that reported net income understates the company's cash-generating ability, though investors should monitor the volatility in working capital changes, which can distort quarterly comparisons.

The trajectory of FCF is highly erratic, with the 2026Q2 surge driven by a sharp revenue increase and a modest working capital outflow, while the prior quarter's FCF was depressed by a $2.5B working capital drag. Over the ten quarters, cumulative FCF of approximately $73.6B is substantial, but the quarterly swings highlight the cyclicality of the business. This pattern suggests that while XOM can generate significant cash in upcycles, investors should expect periodic contractions when prices soften, as evidenced by the -4.5% YoY revenue decline in the latest quarter.

The CapEx/Revenue ratio has trended upward from 6.3% in 2024Q1 to 9.3% in 2025Q4, suggesting an acceleration in growth-oriented spending, likely tied to the Pioneer acquisition and Guyana expansion. While maintenance capex is a baseline, the elevated ratios imply a deliberate push to expand production capacity, which could enhance future cash flows if commodity prices remain supportive. However, the high capital intensity also means that any downturn in prices could strain free cash flow, as seen in 2026Q1 when FCF dropped to $2.2B despite CapEx of $6.5B.

The working capital line is a major source of quarterly noise, with large outflows in 2024Q2 (-$4.8B) and 2026Q1 (-$2.5B) contrasting with inflows in 2024Q3 (+$2.3B) and 2024Q1 (+$2.0B). These fluctuations likely reflect timing of crude purchases and product sales, as well as LIFO inventory effects, which can create non-cash gains or losses. Investors should look through these swings to the underlying operational cash flow, which remains robust, but the volatility warrants monitoring for potential liquidity management issues.

The company consistently allocates roughly $9-10B per quarter to shareholder returns, with dividends stable at ~$4.3B and buybacks ranging from $3.0B to $5.8B. This deployment is supported by strong operating cash flow, which averaged $14.0B per quarter, leaving a comfortable cushion for reinvestment. However, the sustainability of this pace depends on commodity prices; in 2026Q1, when OCF dropped to $8.7B, the combined distributions of $9.2B exceeded OCF, indicating a reliance on cash reserves or debt, though the balance sheet remains fortress-like with a debt/equity of 0.16%.

The cumulative gap of $58.4B between OCF and net income is substantial, driven primarily by D&A (cumulative $65.0B) and working capital inflows. This suggests that XOM's earnings understate its cash-generating power, a common feature in capital-intensive industries. However, the gap also implies that a significant portion of cash flow is being reinvested into the business, as evidenced by cumulative CapEx of $66.2B, which nearly matches cumulative D&A. This balance indicates that XOM is maintaining its asset base while also funding growth, though the sustainability of this model depends on the returns generated from these investments.
