Shares of the San Francisco electric and gas company at last check rose 2.6% to $12.85. The shares initially fell on the news of the deal before rebounding.
PG&E agreed to sell $3.25 billion of common stock at $10.50 a share to a group of large investment firms.
The stock sale deal with Zimmer Partners, Fidelity, Appaloosa and Third Point prices shares of PG&E at a more than 16% discount from their closing price on Friday of $12.52.
The stock is trading at about half its 52-week high above $25, touched last June.
The deal, set to go into effect the day PG&E officially emerges from bankruptcy, is part of the utility company's exit financing plan for emerging from Chapter 11.
PG&E in May said it reached a $13.5 billion settlement with thousands of homeowners in California following a lawsuit over a series of devastating wildfires triggered by the utility giant's equipment.
Faced with $30 billion in potential liability over the wildfires, including the 2018 Camp Fire that destroyed the town of Paradise and killed 85 people, PG&E sought protection from its creditors last year in federal bankruptcy court.
"Today's announcement is another positive step toward PG&E's emergence from Chapter 11" while also "ensuring wildfire victims are paid more quickly," said Jason Wells, executive vice president and chief financial officer of the power company, in a statement.
