Bloomberg reported that Vistra Corp. is expected to be offered a U.S. government loan package of about $4 billion to upgrade its nuclear plants.

The funding would target three facilities: two in Ohio and one in Pennsylvania. U.S. Energy Secretary Chris Wright is expected to make the formal announcement.

Before the report, Vistra shares were trading near $137 before falling to a session low of $135.79. After the report, they recovered to about $139.20.
