Investment bank UBS has lowered it outlook for uranium over the next two years citing lacklustre buyer interest, dashing hopes for a rapid rebound in demand for the controversial energy source.

The broker slashed its uranium price forecast by 9 per cent to $US78 a pound over 2025 and 2026, and cut its share price target for ASX-listed Paladin Energy by 5 per cent to $9.90 and Boss Energy by 3 per cent to $3.40.
