ArcBest Corp (ARCB) Cash Flow Statement

The gap between net income and operating cash flow is the most material signal in this dataset, with quarterly OCF/NI ratios ranging from roughly -9.4x to 4.2x. Such extreme ratios suggest that depreciation of about $40M to $45M per quarter and working capital movements of up to $70M in Q1 2025 are dominating reported earnings, which warrants caution when extrapolating any single quarter. Investors should monitor whether cash conversion normalizes once the working capital cycle stabilizes, since the current pattern may indicate that accounting earnings are a poor proxy for underlying cash generation.

Free cash flow margins ranged from -3.8% to 10.2% over the ten quarters, with only a few quarters reaching margins above 7%, indicating that the business generates inconsistent surplus cash through the cycle. The Q2 2026 spike appears tied to a $37.1M working capital inflow, which may be non-recurring and therefore should not be capitalized into a run-rate valuation. Investors should treat the average FCF margin, rather than any single peak, as the more reliable indicator of cash earning power.

CapEx intensity spiked well above the 1.0% to 1.5% range seen in several 2026 quarters, which suggests that fleet and terminal investment is lumpy and tied to replacement cycles rather than a smooth maintenance baseline. With depreciation and amortization running near $44M per quarter, a sustained CapEx level above that figure would indicate growth-oriented spending, while periods below it may signal under-investment in the asset base. Analysts should separate maintenance from growth capex to judge whether the thin margin profile is being protected or deferred.

The magnitude of these swings relative to net income indicates that collection efficiency and payables management are materially influencing reported operating cash flow. A reversal from a large outflow to a large inflow within a single quarter may reflect collection timing or settlement effects rather than a structural improvement in the business. Investors should monitor days sales outstanding and the trend in working capital across full cycles before treating recent inflows as sustainable.

Buybacks were funded in several quarters where free cash flow was negative, such as Q1 2026 and Q1 2025, which suggests that repurchases may be supported by the balance sheet or prior cash reserves rather than current cash generation. Acquisition outflows were small and inconsistent, with a $26.4M inflow in Q3 2025 that may reflect divestiture proceeds given the reported FleetNet sale. Investors should assess whether cumulative buybacks are sustainable if free cash flow remains as volatile as the recent record indicates.

Summing the disclosed quarters, operating cash flow substantially exceeds net income, which is consistent with heavy non-cash depreciation of roughly $40M to $45M per quarter. This divergence suggests that the earnings base is thin relative to the asset base and that cash metrics may present a more favorable picture than GAAP earnings. Analysts should weigh this against the recurrence of negative quarters, since cumulative cash strength may not persist if depreciation-driven cash flow is offset by replacement capex.
