Arcosa, Inc. (ACA) Cash Flow Statement

The OCF/NI ratio of -0.03 in Q2 2026 starkly contrasts with the prior quarter's 1.90, indicating that the reported net income surge is not translating into cash generation. This suggests the $328.5M net income is heavily influenced by non-cash items, likely a one-time tax benefit or gain, as operating income only grew modestly. Investors should monitor whether future quarters can convert earnings into cash, as the current divergence signals potential earnings quality concerns.

The FCF trajectory is highly erratic, with positive quarters in 2025Q3 and 2024Q4 offset by negative quarters in 2026Q2 and 2025Q1. This volatility appears tied to working capital swings and acquisition timing, as seen in the $179.7M working capital inflow in 2024Q4 versus -$75.6M in 2025Q2. The recent negative FCF in Q2 2026, despite a net income surge, suggests that cash generation is not keeping pace with reported profitability, warranting close monitoring of the company's ability to sustain capital returns.

The rise in CapEx/Rev to 8.9% in Q2 2026 from 3.8% in Q2 2025 suggests Arcosa is investing heavily in fixed assets, possibly for growth in aggregates or utility structures, despite a 10.6% revenue decline. This could signal management's confidence in long-term demand, but it also pressures near-term free cash flow. The elevated capital spending, combined with negative operating cash flow, may indicate a reliance on external financing or cash reserves, which investors should monitor.

The extreme volatility in working capital changes, ranging from +$179.7M to -$80.7M over the past ten quarters, suggests that Arcosa's cash flow is heavily influenced by timing of receivables, payables, and inventory. This pattern may indicate project-based revenue recognition (POC) and large contract milestones, which can distort quarterly cash flows. The recent positive working capital inflow in Q2 2026, despite negative operating cash flow, implies that collections or payables management provided a temporary boost, but the underlying trend remains unstable.

The significant acquisition spending, particularly the $1.2B outflow in Q4 2024, underscores management's strategy to pivot toward construction products, as seen in the StonePoint acquisition. However, the modest buybacks and stable dividends suggest that shareholder returns are secondary to portfolio transformation. The recent $31.3M acquisition in Q2 2026, despite negative free cash flow, may indicate continued M&A appetite, which could strain liquidity if operating cash flow remains weak.

The cumulative OCF of $903.8M versus net income of $668.0M suggests that, on a multi-quarter basis, cash conversion has been strong, but this is distorted by the $1.2B acquisition outflow in Q4 2024, which is not part of operating cash flow. Excluding that, the cumulative OCF would be significantly lower, indicating that earnings quality may be weaker than it appears. The recent negative OCF in Q2 2026, despite high net income, reinforces the need to scrutinize the sustainability of earnings.
