Intuitive Surgical, Inc. (ISRG) Cash Flow Statement

The persistent OCF/NI ratio above 1.0, except for 2025Q1 and 2024Q1, suggests that reported earnings are well-backed by cash generation, with non-cash charges like D&A and SBC providing a cushion. The 2026Q2 ratio of 1.30 reflects a widening gap between net income and operating cash flow, driven by strong collections and controlled working capital outflows. This pattern implies that earnings quality is solid, though investors should monitor the sustainability of such conversion rates as the company scales.

The trajectory shows a clear upward trend, with FCF margins improving from the low 20s in 2024 to the high 20s and low 30s in 2026, far outpacing the peer average of around 20%. This expansion is driven by revenue growth, operating leverage, and moderating capital intensity, as CapEx/Revenue fell from 12.8% in 2024Q1 to 3.9% in 2026Q2. The gap between FCF and net income has narrowed, with FCF now exceeding net income in 2026Q2, suggesting that the company is converting earnings into cash more efficiently than in prior periods.

The sharp reduction in capital intensity, with quarterly CapEx falling from over $300M in 2024 to around $100M in 2026, suggests that the company has largely completed its manufacturing and facility expansion cycle. This trend aligns with the prior income statement analysis showing margin expansion, as lower depreciation and capital requirements boost free cash flow. However, investors should consider whether this lower CapEx level is sufficient to support future growth, particularly in international markets and new product launches, which may require renewed investment.

The large negative working capital changes in most quarters, particularly -$644.8M in 2026Q1, indicate that cash is being tied up in receivables and inventory as the company scales. The positive swing in 2025Q3 suggests a temporary release of cash, but the overall trend points to increasing working capital needs, which could pressure future cash flow if not managed. The company's ability to maintain high OCF/NI ratios despite these swings suggests effective management, but the volatility warrants close monitoring.

After a period of no buybacks in 2024, the company repurchased $1.9B in 2025Q3 and $1.1B in 2026Q1, indicating a new phase of returning capital to shareholders. This deployment is supported by robust free cash flow, which exceeded $700M in those quarters, and a healthy balance sheet. The absence of dividends suggests a preference for buybacks, which may be more tax-efficient and flexible, but investors should assess the sustainability of this pace given the company's growth investments.

The cumulative OCF/NI ratio of approximately 1.10 over the period suggests that earnings are more than fully realized in cash, with non-cash charges like D&A and SBC providing a buffer. This divergence is a positive signal for earnings quality, as it implies that the company is not relying on aggressive accruals to boost reported profits. However, the gap has narrowed in recent quarters as working capital outflows have increased, so investors should watch whether this trend continues.
