Oceaneering International, Inc. (OII) Cash Flow Statement

The aggregate ratio above 1.0 suggests reported profits are broadly backed by realized cash, but the dispersion matters more than the total: in both 2025Q1 and 2026Q1, positive net income coincided with negative operating cash flow, implying accrual build that later unwinds. This is consistent with the net income volatility and non-operating noise identified in the income statement work, so investors should anchor on trailing four-quarter conversion rather than extrapolating any single quarter's 3.10 or -1.64 reading.

The progression from a 4.5% FCF margin in 2024Q2 to 18.1% in 2026Q3 appears to corroborate the utilization-driven margin recovery flagged in the prior analysis, with cash margins rising faster than the reported net margin. However, the recurring first-quarter negatives (-$106.8M and -$76.5M) indicate the trajectory is not linear, and 2026Q3's outsized 3.10 conversion likely embeds a working capital release that may not repeat, warranting investigation into whether the exit-rate margin is sustainable.

Capital intensity of 2.5% to 4.7% of revenue is modest for a fleet-dependent services business, and the recent drift toward the low end while depreciation holds near $27M per quarter suggests the company is prioritizing cash preservation over ROV fleet expansion during the upcycle. This posture flatters near-term free cash flow but may leave asset renewal deferred; if utilization continues climbing, a capex re-acceleration toward or beyond D&A would be a natural signal to monitor.

Because the working capital swing is several times larger than quarterly operating income, collections timing and milestone billings in the Manufactured Products and OPG segments appear to be the primary drivers of reported cash results rather than operating performance. The repetition of first-quarter outflows followed by second-half inflows looks structural rather than idiosyncratic, which implies sequential quarterly guidance should be underwritten on a full-year basis and that a reversal of the 2026Q3 release is the most immediate cash flow risk.

Net acquisition activity was negligible, with only a small 2025Q3 inflow suggesting a minor divestiture rather than M&A, so capital return has absorbed a low-single-digit share of discretionary cash generation. Against the fortress leverage profile noted previously, this retention may indicate deliberate liquidity accumulation ahead of fleet reinvestment, though it equally represents an unresolved capital allocation question for holders given the scale of cumulative free cash flow left unreturned.
