Alaska Air Group, Inc. (ALK) Cash Flow Statement

In 2026Q2, operating cash flow of $185M against a net loss of $76M implies a positive cash conversion, but the negative OCF/NI ratio indicates the loss is not fully cash-based. The large working capital contribution of $37M in 2026Q2 and $385M in 2026Q1 suggests that cash generation is heavily influenced by timing of payables and receivables, which may not be sustainable. Investors should monitor whether operating cash flow can remain positive as working capital normalizes.

The trajectory shows no stable trend, with FCF positive in only four of the last ten quarters. The 2025Q4 FCF of -$440M on a 17.2% capex-to-revenue ratio indicates significant investment outlays, likely related to fleet and integration. Compared to peers like DAL with an 8.9% FCF margin, ALK's volatile and often negative FCF suggests a period of elevated investment that may pressure shareholder returns.

The elevated capex in 2025Q4 and 2025Q2 (13.6% of revenue) suggests growth-oriented spending, possibly for fleet expansion or integration of Hawaiian Airlines. However, the lack of a clear maintenance vs. growth split makes it difficult to assess sustainability. If this capex is growth-oriented, it may support future capacity, but it also strains near-term FCF, as seen in the -$440M FCF in 2025Q4.

The large positive working capital changes in several quarters suggest that ALK is delaying payments or accelerating collections, which boosts operating cash flow temporarily. However, the negative changes in other quarters indicate reversals, making cash flow lumpy. This volatility complicates the assessment of underlying cash generation and may indicate that operating cash flow is not a reliable indicator of core profitability.

The company spent heavily on buybacks in 2025Q2 and 2026Q1, coinciding with negative FCF in those quarters, which may indicate a reliance on cash reserves or debt to fund repurchases. No dividends were paid, so buybacks are the primary return mechanism. Given the volatile FCF, investors should question the sustainability of this deployment strategy if cash generation does not improve.

The large cumulative gap between net income and operating cash flow suggests that earnings are understated relative to cash generation, likely due to heavy depreciation and amortization (averaging ~$180M per quarter) and favorable working capital timing. However, this gap may narrow as working capital normalizes, and the recent net losses in 2026Q1 and Q2 could signal deteriorating fundamentals. The divergence warrants monitoring to see if cash flow can remain robust as earnings recover.
