UBS downgraded its outlook on NuScale Power, citing concerns that likely include valuation, execution risk, or competitive pressures within the small modular reactor nuclear technology space. The shift in analyst sentiment comes as investor enthusiasm for nuclear power stocks has been elevated this year amid rising electricity demand tied to AI data centers. The downgrade adds a note of caution to a nuclear power investment theme that has otherwise attracted strong investor interest as utilities and tech companies seek reliable power sources for expanding data-center capacity.
