IREN shares dropped 8% in Friday pre-market trading after the bitcoin miner-turned-AI cloud company's fiscal fourth-quarter results laid bare the steep near-term cost of its strategic pivot. Adjusted EBITDA plunged 68% quarter over quarter to $19.2 million, and the company recorded a $684 million net loss driven by a $450.4 million non-cash impairment on decommissioned bitcoin mining hardware. Total quarterly revenue fell 5% to $137.2 million, with mining revenue down 40% as power and infrastructure were redirected to AI.
The quarter also marked a structural milestone: AI cloud revenue more than doubled sequentially to $70.5 million, surpassing bitcoin mining revenue of $66.7 million for the first time. AI cloud now contributes 51.4% of IREN's top line, up from less than half a year ago.
Why it matters
This is a classic pay-the-capex-before-you-book-the-revenue print. IREN is converting mining sites into AI infrastructure, and the income statement is bearing the full weight of that transition while the cloud business is still ramping. The numbers point straight at the gap between announced contracts and recognized revenue: management said the company holds $4 billion in contracted annualized run-rate revenue tied to its 2026 capacity, but only $1 billion is currently operational. The market is being asked to underwrite a multi-year build-out at the moment bitcoin mining margins are compressing.
Market impact
The IREN trade is now a reference print for every other bitcoin miner evaluating a similar pivot, especially those sitting on large-scale power capacity. Mining revenue fell 40% sequentially as power and infrastructure were redirected, and rising employee costs ahead of the cloud ramp compounded margin pressure. AI cloud services contributed 51.4% of quarterly revenue while mining generated 48.6%, a near-even split that marks the first time the new business has outweighed the legacy one. The next data points investors will watch are quarterly disclosures showing how quickly the remaining $3 billion in contracted pipeline converts to recognized revenue, and whether the AI unit can sustain its doubled sequential growth rate.
