$IREN is now facing a valuation reality check as Wall Street starts separating the AI opportunity from execution risk.

Rothschild Redburn initiated coverage with a Neutral rating and a $40 price target, below IREN's reported $46.68 share price.

Their DCF framework puts the focus on unit economics and the ability to convert the company's AI infrastructure pipeline into actual revenue.

The bull case is still substantial. IREN's Q4 FY2026 AI Cloud revenue jumped to $70.5M from $33.6M, while the company says its 2026 capacity is effectively sold out and could support around $4B in ARR.

But the numbers also show the transition isn't painless. Total Q4 revenue fell to $137.2M, adjusted EBITDA dropped to $19.2M, and the company recorded a $684M net loss, including a $450.4M noncash impairment tied to mining hardware.

AI demand is clearly growing, but execution, financing and the timing of the 2027 capacity ramp will determine how much of that potential becomes actual earnings and cash flow.
