InfuSystem Holdings, Inc. (INFU) Cash Flow Statement

The divergence between GAAP earnings and operating cash flow is dominated by depreciation and amortization, which has run at $2.9M to $3.4M per quarter and frequently exceeds reported net income by itself. This pattern suggests a heavy depreciable asset base relative to reported profitability, meaning the low net margin likely understates underlying cash economics. However, quarters such as 2025Q1 and 2026Q1 show the OCF/NI ratio compressing sharply during loss-making periods, so the quality signal appears durable only on a cumulative rather than single-quarter basis.

The FCF trajectory points to a business that crossed an inflection in mid-2025, coinciding with the gross margin regime break identified in the income statement work. Volatility still matters: two of the ten quarters produced negative FCF (2024Q2 at -$5.3M and 2025Q1 at -$1.6M), each tied to capex spikes rather than operating deterioration. The 22.7% FCF margin in 2026Q2 compares favorably against peer OPRX's 18.6% and HCSG's 5.8%, but the sequential lumpiness argues against extrapolating the current run-rate linearly.

This collapse in capex intensity is one of the more consequential shifts in the model: quarterly capex peaked at $7.6M in 2024Q2 and has since settled below $1M in the most recent quarter, which may indicate completion of a growth investment cycle and a transition into harvest mode. The durability of such a low reinvestment rate warrants monitoring, because cumulative capex of roughly $28.3M over the window sits below the $32.1M cumulative D&A charge; a persistent gap between depreciation and capex typically implies asset base drawdown rather than efficiency.

A gap of this magnitude in the direction of cash exceeding earnings is generally a favorable quality-of-earnings signal, suggesting reported net income is depressed by depreciation rather than inflated by aggressive revenue recognition, and cumulative D&A of approximately $32.1M accounts for the vast majority of the difference. Working capital, by contrast, has been a cumulative net drain of roughly $6.5M despite large quarterly swings, so the cash conversion advantage does not appear to rest on systematic payables stretching or inventory liquidation that would reverse.

The deployment pattern is consistent with a business entering a post-investment phase: no dividends have been paid, and the trailing four-quarter buyback total of approximately $9.3M represents a step-up versus the roughly $2.0M deployed across 2024Q1-2024Q3. A single $577K net acquisition in 2026Q2 suggests M&A remains opportunistic rather than a primary capital use. Because SBC continues to run near $1.2M per quarter, investors should cross-check the buyback pace against diluted share count trends in the filings to gauge the net reduction in shares actually outstanding.
