IREN Expands GPU Fleet to 150,000 Amid Persistent Execution Risks

What happened

IREN announced purchase agreements for over 50,000 NVIDIA B300 GPUs, expanding its total fleet to 150,000 units to bolster AI cloud services tied to its Microsoft contract. This move aligns with its strategic pivot from Bitcoin mining to AI infrastructure, but the DeepValue report highlights that GPU count growth alone doesn't guarantee revenue, as AI revenue was only $17.3M last quarter versus $167.4M from mining. Critical execution hurdles remain, including Dell GPU shipments starting March 2026 with tight payment terms, internal control weaknesses, and the risk of Microsoft contract termination if delivery milestones are missed. Investors must look beyond the headline numbers to assess whether this expansion converts into recognized AI revenue, given the company's history of financial restatements and high valuation multiples. The next 6-12 months will be decisive, requiring visible quarterly AI revenue step-ups and successful tranche acceptances to validate the buildout.

Implication

The GPU purchase increases IREN's capacity but also raises capex and working capital demands, with Dell's 30-day payment terms adding near-term financing pressure. AI revenue must grow from $17.3M to over $35M quarterly by August 2026 to meet the report's upside case, making upcoming disclosures critical for validating the ramp. Internal control weaknesses and past restatements erode confidence in financial reporting, complicating the assessment of cash conversion and unit economics during this capital-intensive phase. With the stock priced for success at current levels and EV/EBITDA at 68.68, any delays in GPU commissioning or Microsoft acceptance could trigger significant downside. Therefore, the 'WAIT' rating remains appropriate, as investors should monitor for sequential AI revenue growth and milestone completions before reconsidering the investment thesis.

Thesis delta

The GPU expansion reinforces IREN's aggressive buildout strategy but does not shift the core investment thesis, which still hinges on 2026 execution and AI revenue conversion. Investors must continue to require evidence of sustained AI revenue growth above $35M quarterly and remediation of internal controls to upgrade from the current 'WAIT' rating.
