The reported quarter missed the near-term revenue bar. Q4 revenue was $137.2 million versus published consensus of roughly $145 million, a miss of about 5%; adjusted EBITDA fell to $19.2 million from $59.5 million in Q3. The weak comparison matters because AI Cloud revenue is growing, but Bitcoin mining revenue dropped sharply quarter over quarter as capacity shifts toward AI. 〔0〕
| US$ millions | Q4 FY26 / FY26 | Comparison | Market read |
|---|---|---|---|
| Q4 total revenue | 137.2 | Q3: 144.8 | Below roughly $145M consensus |
| Q4 AI Cloud revenue | 70.5 | Q3: 33.6 | More than doubled sequentially |
| Q4 Bitcoin mining revenue | 66.7 | Q3: 111.2 | Fell materially |
| Q4 adjusted EBITDA | 19.2 | Q3: 59.5 | Margin fell to 14% from 41% |
| FY26 total revenue | 707.0 | FY25: 501.0 | Higher, but mix is changing |
| FY26 AI Cloud revenue | 128.8 | FY25: 16.4 | Approximately eightfold increase |
| FY26 adjusted EBITDA | 245.7 | FY25: 269.7 | Down despite revenue growth |
| FY26 net income | (702.6) | FY25: 86.9 | Hit by $638.8M impairment |
The strategic news is materially better than the reported quarter. IREN disclosed $4 billion of contracted ARR for 2026 capacity and $1 billion of operating ARR as of August 26, while also signing a new multi-year contract with a leading frontier AI lab. 〔1〕 That is a meaningful increase in commercial visibility, but ARR is not GAAP revenue and the company says the $4 billion target depends on commissioning, testing, customer acceptance, utilization and pricing assumptions.
Execution and financing reduce—but do not remove—the delivery risk. Horizon 1 has been delivered to Microsoft, and the company says Horizon 2 is commissioning while Horizons 3 and 4 target Q4 2026 delivery. 〔2〕 New GPU financings total $2.8 billion, while the Microsoft financing and prepayments cover most associated GPU costs; that supports expansion but also leaves IREN reliant on large-scale construction, hardware deployment and customer acceptance.
The transition is generating real cash but still carries heavy economic costs. FY26 operating cash flow of $2.1 billion was boosted by $1.84 billion of deferred-revenue inflows, while investing cash outflow reached $4.72 billion and financing cash inflow was $9.68 billion (Cash Flow statement). Net income fell to a $702.6 million loss, including $638.8 million of impairments tied primarily to retiring Bitcoin hardware (Income Statement).
Net: the filing is a mixed update, not a clean earnings win. The new AI contracts, $4 billion capacity backlog and funded GPU buildout improve the long-term commercial picture, but the actual quarter missed consensus, EBITDA compressed, and the business remains in a capital-intensive conversion phase. The scorecard is therefore a Q4 earnings miss, offset by strategically stronger AI Cloud visibility.
