Backblaze Q3 Revenue Accelerates to 26% Growth, but Key Proof Points Remain Unresolved

What happened

Backblaze reported Q3 revenue of $47 million, up 26% year over year, with accelerated growth driven by B2 Cloud Storage and ongoing capacity investments for AI-related demand. This compares to Q1's 12% growth, signaling a meaningful step-up, though the brief announcement does not disclose whether CoreWeave revenues were recognized or how B2 retention fared after the May 2026 price increase. The company continues to build capacity for AI workloads, aligning with its neocloud strategy, but gross margin and cash flow details are absent from the market update. Given prior caution around CoreWeave revenue recognition and post-price-change B2 retention, this update is positive but incomplete. Investors should await full filing details to assess the quality and sustainability of the acceleration.

Implication

Holders can maintain positions given the clear revenue inflection, but new capital should wait for confirmation that CoreWeave revenues are recognized and that B2 net revenue retention remained near 110% after the May price increase. The reported 26% growth likely includes some benefit from the pricing action and possibly CoreWeave utilization, but without margin and retention data, the durability of this acceleration is uncertain. If Q4 guidance or subsequent filings show continued B2 strength and margin stability, the bull case strengthens toward the $18 target. Conversely, if the growth was driven by one-time AI capacity builds or if retention deteriorated, the stock could revert toward the $10-12 range. Given the current price near $14.60, the risk/reward is balanced, so waiting for the 10-Q is prudent.

Thesis delta

The investment thesis is partially validated by the revenue acceleration, suggesting B2 demand is real and AI capacity builds are translating into sales. However, the core uncertainties remain: CoreWeave revenue recognition status and post-price-change B2 retention are still unconfirmed. Thus, the WAIT rating is maintained, but the probability of the bull case has increased modestly, and the next few weeks will be critical to determine if this becomes a BUY.
