Backblaze Q1 2026 slides: AI storage drives 24% B2 growth By Investing.com

Backblaze reported Q1 2026 revenue of $38.7 million, up 12% year over year and above the $37.79 million consensus, while non-GAAP EPS of $0.04 beat expectations of -$0.0043. Gross margin improved to 61% from 56%, adjusted EBITDA rose to $10.1 million with a 26% margin, and full-year 2026 revenue guidance was raised by $5 million to $161.5-$163.5 million. AI-related customers grew 76% year over year, and the stock jumped more than 70% after hours on the earnings beat and improved outlook.

Analysis

BLZE is moving from a “story stock” to a plausibly self-funding infrastructure asset, which matters because the market typically pays a much higher multiple once growth and margin expansion reinforce each other. The key second-order effect is that AI storage demand is not just incremental revenue — it improves product mix, increases the share of customers with usage-based expansion potential, and gives management a cleaner path to leverage fixed infrastructure costs. That creates a near-term valuation rerate even if absolute revenue size remains modest.

The competitive edge is narrower than the headline move suggests. Backblaze is not displacing hyperscalers; it is exploiting a cost/performance gap where flash-heavy stacks are uneconomic and where incumbent storage vendors are slowed by complexity, pricing rigidity, or poor fit for active AI data. The real beneficiaries may be downstream AI tooling ecosystems and neoclouds, because a cheaper storage layer lowers the all-in cost of training pipelines and makes more marginal AI projects viable.

The risk is that this is still early-cycle demand with lumpy customer concentration. In the next 1-2 quarters, any slowdown in AI customer expansion, usage normalization, or a single large account rebaselining could compress the narrative quickly because the stock has already priced in a steeply higher growth trajectory. Over 6-12 months, the bigger watch item is whether the company can translate better gross margin into durable free cash flow without re-accelerating opex too aggressively.

The consensus likely underestimates how much of the move is a multiple expansion event rather than a fundamental step-change. If management sustains 20%+ storage growth while holding EBITDA margins in the low-to-mid 20s, the market will likely begin valuing BLZE against higher-quality infrastructure names instead of legacy SMB storage peers. That said, the post-earnings gap leaves limited margin for error, so the trade should be approached as momentum with a catalyst window, not a permanent re-rating thesis.

Key Decisions for Investors

• Long BLZE on a pullback over the next 1-2 sessions, looking for a retest after the gap-up; thesis is continued multiple expansion if management can validate AI demand in the next quarter. Trim risk aggressively if the stock fails to hold post-earnings gains into the first week.
• For upside convexity, buy BLZE call spreads 1-2 months out rather than outright stock; the setup is strong but post-earnings implied move capture is already partially realized, so defined risk is preferable.
• Pair trade: long BLZE / short NTAP over 1-3 months. The trade expresses the market’s willingness to reward AI-adjacent storage growth while fading slower-moving legacy storage exposure; the spread should widen if AI storage remains the dominant narrative.
• Use a stop on BLZE if next-quarter commentary shows AI revenue concentration or usage volatility from a small number of accounts; that is the highest-probability catalyst for a fast de-rating.
• Watch VRSN only as a relative-quality hedge, not a direct competitor; if the market shifts from growth to defensiveness, rotate partial exposure from BLZE into higher-cash-generation infrastructure names.
