Littelfuse, Inc. (LFUS) Cash Flow Statement

The ratio of operating cash flow to net income running near or above 1.5x across most recent quarters suggests that reported earnings are conservatively measured relative to cash, with large non-cash amortization and working capital inflows contributing to the gap. The 2026Q3 working capital inflow of $75.7M appears to account for a meaningful share of that quarter's operating cash flow, so investors should monitor whether this release is repeatable. The negative operating cash flow conversion implied in the 2024Q4 and 2025Q4 quarters, where net losses were paired with positive operating cash flow, indicates that the large charges in those periods were largely non-cash and did not reflect cash deterioration.

The expansion in free cash flow margin across the ten-quarter window appears driven more by operating cash flow growth than by any reduction in capital spending, since capex has remained in a relatively narrow band of roughly $10M to $26M per quarter. The 2026Q3 free cash flow of $215.7M is well above the trailing quarters, which warrants caution because it reflects a single period's working capital release rather than a clearly established new run rate. Investors should weigh the sustainability of this trajectory against the more modest 9.8% to 17.2% margins observed in the first two quarters of 2026.

Capex as a percentage of revenue remained consistently low, with the highest intensity of 4.9% in 2024Q4 coinciding with a period of elevated investment activity. Depreciation and amortization of roughly $32M to $36M per quarter exceeds capex in most periods, which may indicate that the asset base is being run down slightly or that amortization of acquired intangibles inflates the D&A figure. Investors should distinguish between maintenance and growth spending, as the reported figures do not separate these, and a sustained capex level below D&A could eventually constrain capacity if not monitored.

The magnitude of these swings suggests that quarterly operating cash flow is heavily influenced by timing of receivables collection, inventory movements, and payables, rather than by steady underlying cash generation. The sequence of large inflows followed by outflows across 2024 through 2026 may indicate active inventory and receivables management, though it could also reflect distributor destocking dynamics common in this sector. Investors should evaluate trailing multi-quarter cash flow rather than any single quarter to avoid overstating the underlying cash profile.

Aggregating the reported quarters, net income is depressed by two large negative quarters while operating cash flow remains positive throughout, which suggests the earnings shortfall is primarily accounting-driven rather than a sign of weakening cash economics. This pattern is consistent with heavy amortization and impairment charges associated with the company's acquisition history. Investors should nonetheless monitor whether recurring acquisition-related costs continue to depress reported earnings, as persistent divergence can complicate valuation if the market anchors to GAAP profitability.
