Backblaze, Inc. (BLZE) Cash Flow Statement

The persistent gap between net income and operating cash flow is striking: every quarter shows negative net income but positive operating cash flow, with Q2 2026 OCF of $10.4M versus a net loss of $5.1M. This is largely attributable to non-cash charges—D&A of $7.0M and SBC of $9.2M—which together exceed the loss. The pattern implies that reported losses overstate the cash drain, but investors should note that SBC is a real economic cost that dilutes shareholders, even if it does not affect cash balances.

The FCF trajectory is markedly positive: after hovering near breakeven or negative in 2024, FCF jumped to $11.7M in Q2 2026, a margin of 27.5%. This is driven by a surge in operating cash flow to $10.4M, while capex remained minimal at $0.8M (1.9% of revenue). The low capex is surprising for a storage company, suggesting either a pause in infrastructure investment or a shift to more efficient capacity utilization; investors should monitor whether this is sustainable or a temporary lull.

Capex has been volatile, peaking at $3.1M in Q3 2025 and Q4 2024, but dropping to $0.8M in Q2 2026. The capex-to-revenue ratio of 1.9% is unusually low for a cloud storage provider, which typically requires heavy investment in servers and data centers. This could indicate that Backblaze is leveraging its software-defined storage to extend the life of existing hardware, but it also raises questions about whether capacity can keep pace with the 34% B2 growth. If demand accelerates, capex may need to rise sharply, pressuring FCF.

The working capital line has been a persistent drag on operating cash flow, with negative changes in eight of the last ten quarters. In Q2 2026, the -$2.4M change reduced OCF, and Q1 2026 saw a -$5.4M impact. This likely reflects increasing receivables from B2 customers and possibly higher prepaid expenses. While the drag is not alarming given the overall OCF growth, it indicates that the company is not yet generating cash from its working capital cycle, and investors should watch for any deterioration in collection efficiency.

Capital deployment is heavily skewed toward reinvestment: dividends are zero, buybacks are negligible (less than $1M per quarter), and there are no acquisition outlays. The small buybacks in recent quarters may be opportunistic or to offset SBC dilution, but they are immaterial. This is typical for a company in a growth phase, but it means shareholders rely entirely on operational performance for returns. The lack of acquisitions also suggests organic growth is the primary strategy, which may limit near-term diversification.

The cumulative gap between net income and operating cash flow is stark: net losses of $85.4M versus OCF of $49.6M over the ten-quarter period. This is driven by substantial D&A and SBC, which are non-cash but represent real economic costs. The positive OCF suggests the business is self-funding its operations on a cash basis, but the persistent losses indicate that the company is not yet profitable on a GAAP basis. Investors should recognize that the cash flow statement paints a more favorable picture than the income statement, but the SBC component is a genuine shareholder cost that will continue to dilute value.
