Waste Connections, Inc. (WCN) Cash Flow Statement

The persistent gap between operating cash flow and net income, which reached 2.47x in 2026Q2, suggests that reported earnings understate actual cash generation, likely due to significant non-cash expenses like depreciation and amortization. This high conversion ratio implies that the company's earnings are of high quality, with minimal reliance on accruals. Investors should note that the 2024Q4 net loss of -$196M, as reported, was an anomaly that did not impair cash generation, as operating cash flow remained positive at $568.9M.

The wide quarterly swings in FCF margin, from 40.2% in 2026Q2 to 6.5% in 2025Q4, are primarily driven by the timing of capital expenditures and working capital fluctuations, as evidenced by the negative working capital changes in most quarters. Despite this volatility, the cumulative FCF over the last four quarters remains substantial, suggesting that the company's core operations generate ample cash. The FCF margin of 40.2% in 2026Q2 appears to be an outlier, likely due to a favorable working capital release, and investors should monitor whether this level is sustainable.

The capital expenditure ratio, which averaged around 12% of revenue, underscores the high fixed-cost nature of the waste management industry, with investments in landfill airspace and equipment being essential for long-term growth. The elevated capex in 2025Q4 (16.6% of revenue) and 2024Q4 (17.6%) suggests that the company may be investing in new landfill capacity or environmental compliance, which could pressure near-term FCF but support future growth. Given the company's strong operating cash flow, this level of capex appears manageable, but investors should monitor whether these investments yield the expected returns.

The persistent negative working capital changes, with the exception of 2024Q2, suggest that the company is effectively managing its receivables and payables, converting sales into cash quickly. This efficiency is a key contributor to the high OCF/NI ratio, as it reduces the need for external financing. However, the positive working capital change in 2024Q2 ($2.6M) was minor and did not disrupt the overall trend, indicating that the company's working capital management remains stable.

The company has been actively repurchasing shares, with buybacks ramping up from zero in 2025Q3 to $330.5M in 2026Q2, suggesting management's confidence in the stock's value. Simultaneously, acquisitions have been a consistent use of cash, with notable outflows in 2024Q1 ($1.2B) and 2024Q3 ($574.6M), reflecting the company's tuck-in M&A strategy. Dividends have grown steadily, from $73.6M in 2024Q1 to $88.4M in 2026Q2, indicating a shareholder-friendly capital allocation policy. The combination of buybacks and acquisitions appears to be well-supported by operating cash flow, but investors should monitor the pace of M&A to ensure it does not strain the balance sheet.

The cumulative gap between operating cash flow and net income, which totals approximately $3.5B over the past ten quarters, is largely attributable to non-cash charges such as depreciation and amortization, which averaged over $300M per quarter. This divergence suggests that the company's earnings quality is high, as cash flows are not being artificially inflated by aggressive revenue recognition. However, the 2024Q4 net loss of -$196M, which was driven by one-time charges, contributed to the gap, and investors should consider whether such charges are recurring. The sustained cash generation provides a solid foundation for the company's capital deployment activities.
