Ducommun Incorporated (DCO) Cash Flow Statement

The OCF/NI ratio of 1.64 in 2026Q2 marks a sharp recovery from the -8.02 in 2025Q4, indicating that the reported net income is now backed by actual cash generation. The persistent gap between net income and operating cash flow in earlier quarters, particularly the -$74.7M operating cash outflow in 2025Q4, appears tied to working capital swings rather than core profitability, as operating margins remained positive. Investors should monitor whether this conversion improvement is sustainable or a one-quarter phenomenon.

The FCF trajectory shows a clear V-shaped recovery, with the 2026Q2 FCF margin of 13.3% far exceeding the 7.4% in 2024Q4 and the negative prints in 2025Q1 and 2025Q4. This improvement appears driven by both stronger operating cash flow and modest capex, suggesting that the company is converting its revenue growth into cash more efficiently. However, the volatility in FCF across quarters—ranging from -36.3% to 13.3% margins—highlights the lumpy nature of working capital and program timing, warranting caution in extrapolating the latest quarter's strength.

Capex/Revenue has consistently stayed below 3%, with 2026Q2 at 1.6%, suggesting that Ducommun's asset base is not requiring heavy reinvestment to support growth. This low capital intensity, combined with D&A of roughly $8.5M per quarter, implies that maintenance capex is likely covered, and the company may be under-investing relative to its growth ambitions. The modest capex could limit future capacity expansion, but it also means that operating cash flow is largely available for debt reduction or shareholder returns.

The negative working capital changes in every quarter—ranging from -$4.5M to -$24.8M—suggest that Ducommun is consistently investing in working capital, likely to support program ramps and build inventory ahead of deliveries. The 2026Q2 improvement to -$6.1M, however, indicates a moderation in that drag, which contributed to the strong FCF. Investors should monitor whether the company can sustain this improved working capital efficiency, as the prior quarters' heavy outflows may reflect structural needs of the aerospace supply chain.

The $13.2M buyback in 2026Q2 contrasts with negligible repurchases in prior quarters, suggesting management's confidence in the company's cash generation and valuation. The absence of dividends indicates a preference for reinvestment or debt reduction, but the low debt-to-equity ratio of 0.52% suggests the balance sheet has capacity for more aggressive capital returns. The timing of the buyback, following the strong EPS beat, may indicate that management views the stock as undervalued, though the sustainability of this deployment remains to be seen.

Despite the -$64.4M net loss in 2025Q3, the cumulative OCF/NI ratio of 1.37 over the period implies that the company's cash-generative ability is not fully reflected in net income, likely due to non-cash charges like impairments or tax adjustments. This divergence supports the view that the underlying business is healthier than headline earnings suggest, but it also highlights the impact of one-time items on reported profitability. Investors should focus on operating cash flow as a more reliable indicator of the company's financial health, while remaining alert to the potential for future non-cash charges.
