Watsco, Inc. (WSO) Cash Flow Statement

The negative OCF in Q1 and Q2 of 2025 and 2026 is typical for a seasonal HVAC distributor, as cash is tied up in inventory ahead of the summer peak. However, the magnitude of the swings—OCF/NI of -2.22 in Q1 2025 versus 5.57 in Q4 2025—suggests that quarterly net income is not a reliable proxy for cash generation. Investors should focus on annual cash conversion, which appears more stable, but the quarterly volatility warrants monitoring for any structural deterioration in working capital efficiency.

The FCF trajectory is dominated by seasonal patterns, with Q4 consistently generating the bulk of annual FCF due to inventory liquidation and receivables collection. While the cumulative FCF over the past four quarters appears healthy, the negative FCF in Q1 and Q2 of 2026 suggests that the company is investing in working capital ahead of the peak season. This is not necessarily a red flag, but it does mean that FCF growth is not smooth and may be misinterpreted if analyzed on a quarterly basis.

CapEx of roughly $8-10 million per quarter is minimal relative to revenue of over $2 billion, indicating that the business requires very little fixed asset investment to sustain operations. This low capital intensity supports the company's ability to generate high FCF margins and fund its growing dividend. However, the low CapEx also suggests that growth is primarily driven by acquisitions and working capital investment, which may carry different risk profiles than organic fixed asset expansion.

The working capital changes are the primary driver of the quarterly OCF volatility, with large negative changes in Q1 and Q2 (inventory build-up) and large positive changes in Q3 and Q4 (inventory liquidation and receivables collection). The Q2 2026 working capital change of -$70.0M is smaller than the -$238.9M in Q2 2025, which may suggest a more cautious inventory approach given the persistent revenue decline. However, the continued negative working capital changes in Q1 and Q2 of 2026 indicate that the company is still investing in inventory, which could be a risk if demand does not recover as expected.

The company has consistently increased its dividend, with quarterly payments rising from $96.8M to $134.1M over the period. However, in quarters with negative OCF (e.g., Q1 2026), the dividend exceeds operating cash flow, indicating that the company is relying on its cash balance or short-term borrowings to fund the payout. While the balance sheet appears healthy with low debt, investors should monitor whether the dividend growth is sustainable if revenue contraction persists and working capital needs remain elevated.

The cumulative OCF slightly exceeds net income, indicating that, on a multi-year basis, earnings quality is solid and accruals are not a major concern. However, the quarterly divergence is extreme, with OCF/NI ranging from -2.22 to 5.57. This suggests that investors should not read too much into any single quarter's cash flow, but rather focus on the annual or cumulative figures. The positive cumulative divergence may also reflect the impact of non-cash items like D&A and SBC, which are added back to OCF, but the overall picture is one of a business that generates cash in line with earnings over time.
