Winston. Tritton was most recently executive vice president and chief merchandising officer at Target. His immediate focus will be on "accelerating the [c]ompany's ongoing business transformation," the home goods retailer said in a press release.

Separately, Target announced that Senior Vice President of Operations Michael Fiddelke will become executive vice president and CFO on Nov. 1. The retailer's shares dropped 1%, after the company's stock hit a YTD high earlier Wednesday.

PG&E shares plunged more than 25% after a California judge granted a motion from a group of claimants and senior note-holders led by Elliott Management, which would open the way to a rival restructuring plan. The claimants and creditors must file their plan by Oct. 17, the judge ordered.

Shares of Sprint popped nearly 3% after the bell following Mississippi's Attorney General Jim Hood's settlement with T-Mobile to drop his state's legal challenge against the merger between the two carriers in exchange for new T-Mobile 5G networks, among other commitments. Within six years, New T-Mobile must cover at least 92% of Mississippi's general population and 88% of its rural population with 5G service, according to the terms of the agreement. So far, more than a dozen other state attorneys general have signed onto the multi-state lawsuit opposing the merger, Reuters reported.
