Yahoo Finance analysis indicates that IREN Limited is transitioning from Bitcoin mining to AI business. Its Q2 revenue was $137.2 million, missing market expectations by 2.52%. GAAP net loss was $684 million, primarily due to a $450.4 million impairment charge on mining equipment, but AI cloud revenue doubled quarter-over-quarter to $70.5 million. Nebius Group's Q2 revenue was $582.3 million, a 454.04% year-over-year increase, exceeding expectations by 1.33%. AI cloud adjusted EBITDA reached $285.7 million with a gross margin of 50%, and the company secured four contracts averaging over $1 billion each, with remaining performance obligations totaling $37.49 billion. Analysts believe that despite Nebius' strong performance and a 150% year-to-date stock price increase, 59% of its revenue comes from three clients, posing a customer concentration risk. In contrast, IREN's stock price has fallen 6% year-to-date; if it can deliver Horizon 2-4 on schedule and secure financing, its AI transformation could present a contrarian entry opportunity.
