Current Thesis

Backblaze’s artificial-intelligence storage thesis now depends on converting the CoreWeave contract into reported growth while absorbing upfront capacity spending; the next quarterly results test that conversion, and a weekly close below $13 invalidates the price-recovery case. The five-year agreement announced on 2026-06-23 was approximately $335 million, according to the company disclosures cited in the preceding coverage.

The 2026-09-09 Investor Day materially updated the financing story. Chief Financial Officer Marc Suidan said B2 revenue growth should reach at least 40% for the remainder of 2026 and through 2027, and explicitly linked the financing proceeds to capital expenditure. These are management expectations, not measured results. The earlier interpretation that capacity spending was merely a possible use of proceeds is therefore superseded. Investor Day transcript

The narrative remains saturated in this assessment: five analyst firms raised targets on 2026-08-04, Citizens reiterated its $21 target on 2026-09-14, and the supplied adjusted market close was $13.16 on 2026-09-18. This is an inference about an established story failing to regain price confirmation, not a measurement of investor ownership. A recovery above the publicly documented 2026-08-19 close of $16.88 alongside delivery of quarterly guidance would overturn that assessment. Citizens action reported by Investing.com

Bullish and bearish views on Backblaze, Inc.

The model's bull view on Backblaze, Inc. (BLZE), in brief: Storage growth already accelerated. Backblaze reported B2 Cloud Storage revenue of $26.6 million for Q2 2026, up 34% year over year, on 2026-08-03. Total revenue was $42.7 million, up 18%; the distinction matters because the storage thesis has stronger measured growth than the… The bear view: Cash spending precedes revenue. At Investor Day on 2026-09-09, Suidan forecast negative free cash flow for four to five quarters and potential gross-margin compression of 300–600 basis points through mid-2027. Management attributed the pressure to capacity deployment ahead of… Both cases follow in full.

Bull Case

• Storage growth already accelerated. Backblaze reported B2 Cloud Storage revenue of $26.6 million for Q2 2026, up 34% year over year, on 2026-08-03. Total revenue was $42.7 million, up 18%; the distinction matters because the storage thesis has stronger measured growth than the company overall. Q2 results
• Contract commitments support the story. The 2026-08-03 Q2 disclosures attributed $313 million of remaining performance obligations to CoreWeave, net of $22 million of warrant value. That is contracted future business; its conversion into quarterly revenue remains the test.
• WEKA broadens the product connection. The 2026-09-09 announcement connects WEKA NeuralMesh’s performance storage with Backblaze B2’s capacity storage. Certification was still underway, and the release disclosed no contract value or minimum revenue commitment; it establishes a product collaboration without establishing another CoreWeave-scale customer. Joint announcement

Bear Case

• Cash spending precedes revenue. At Investor Day on 2026-09-09, Suidan forecast negative free cash flow for four to five quarters and potential gross-margin compression of 300–600 basis points through mid-2027. Management attributed the pressure to capacity deployment ahead of revenue; those expectations qualify the earlier positive-cash-flow narrative. Investor Day transcript
• Legacy revenue dilutes storage growth. Computer Backup revenue fell 2% year over year to $16.1 million in Q2 2026, according to the 2026-08-03 release. The same release reported a $5.1 million net loss despite $12.8 million of adjusted earnings before interest, taxes, depreciation and amortization. Q2 results
• Financing complicates supply attribution. Backblaze priced $175 million of convertible notes on 2026-08-19, according to its financing announcement cited in the preceding coverage. The dated short-interest observation available here covers 2026-08-14, before that financing; it cannot establish whether subsequent weakness reflects convertible hedging.

Setup & Price Structure

The supplied adjusted series records a $13.16 close on 2026-09-18, 35.6% below its $20.43 trailing-year high, despite a three-month price increase of 62.1%. The 14-day relative strength index was 39.4. These observations describe a substantial retreat within a still-positive three-month move; they do not establish a completed base.

The $13 weekly-close threshold remains the published thesis boundary from 2026-09-06. The $16.88 market close associated with the 2026-08-19 convertible pricing provides a documented recovery reference. For this forecast, the recovery case plays out only if a weekly close above $16.88 accompanies next-quarter revenue meeting the $44.4 million guidance floor before invalidation.

Analyst attention is observable: Needham maintained its $23 target on 2026-09-10, followed by Citizens’ $21 reiteration on 2026-09-14. Those actions do not measure fresh demand. No current moving-average series, ownership-flow series or post-financing short-interest observation is established by the evidence used here, so a stronger crowding claim is unsupported.

The next quarterly-results date is unconfirmed in the available evidence. The substantive financial test remains Q3 2026 revenue against the $44.4–44.8 million guidance issued on 2026-08-03; the elapsed 2026-09-09 Investor Day is no longer an upcoming catalyst. Q2 guidance

What Would Change Our Mind

The post-CoreWeave recovery structure breaks on a weekly close below $13, the research boundary retained from the 2026-09-06 note. Separately, Q3 2026 revenue below the company’s 2026-08-03 guidance floor of $44.4 million would contradict the near-term conversion case.

A weekly close above the 2026-08-19 reference close of $16.88, accompanied by delivery of that revenue floor, would establish the defined recovery outcome. A newly disclosed customer commitment with quantified economics would also strengthen the repeatability argument; the 2026-09-09 WEKA release does not supply those economics. WEKA announcement

Correlation Notes

This remains a single-name case rather than a demonstrated group move. The approximately $335 million CoreWeave agreement announced on 2026-06-23 establishes an operating connection to specialist artificial-intelligence cloud infrastructure, but no paired return series is available to establish stock-price correlation. The 2026-09-09 WEKA collaboration supplies another product connection, not evidence of synchronized market performance. WEKA announcement
