IREN Shares Slide 8% as AI Transition Costs Hit Earnings

IREN is remaking a business built around bitcoin mining into an AI cloud platform, using its portfolio of power, land and data centers to meet surging demand for GPU computing. The shift could reduce its exposure to cryptocurrency cycles and open a larger, contract-backed revenue stream. But converting mining sites, buying hardware and expanding staff require heavy upfront investment before the new capacity contributes fully, leaving execution, financing and near-term profitability at the center of investors’ assessment.

On Aug. 27, IREN reported results for the fiscal fourth quarter ended June 30, 2026. Revenue fell 5% sequentially to $137.2 million, adjusted EBITDA dropped 68% to $19.2 million and the company posted a $684 million net loss, including a $450.4 million non-cash impairment tied mainly to retired mining equipment. AI cloud revenue more than doubled to $70.5 million and exceeded bitcoin mining revenue of $66.7 million for the first time. IREN said 2026 capacity carries $4 billion of contracted ARR, with $1 billion operating; shares fell 8% in Aug. 28 premarket trading.
