Companies to watch: Pivotal in buyout talks, Canopy Growth posts a loss, iHeartMedia's strong quarter

Here are the companies the Yahoo Finance team is watching for you today.

Software company Pivotal (PVTL) is skyrocketing amid word it could soon have a new owner. VMware is in talks to buy the company's shares for $15 dollars a piece. Both companies are controlled by Dell and the purchase would simplify Dell's ownership structure.

Canopy Growth's (CGC) earnings went up in smoke last quarter. The cannabis company reported a nearly $1 billion loss, as costs grew and some warrants from a big investment from Constellation Brands (STZ) expired. It was the first earnings report since CEO Bruce Linton was ousted. The acting CEO says they remain focused on expanding and evolving the business.

It was a big quarter back on the public markets for iHeartMedia (IHRT). The radio station owner posted a revenue beat in its first report after emerging from bankruptcy. Net income topped $11 billion dollars, and it has reaffirmed its guidance for the rest of the year. The company says the results show the "resilience and growth" of the business.

PG&E (PCG) seems to be having problems with its tree trimming program. A federal court monitor has found issues with the electric company’s effort to trim trees to reduce the risk of sparking wildfires. The monitor called PG&E’s quality of completed work on the vegetation-management questionable. The court has been cracking down after state investigators tied PG&E equipment to deadly wildfires in 2017 and 2018.

U.S. aviation regulators want to streamline the return of Boeing's (BA) 737 Max jet, which was grounded more than six months ago following two deadly crashes, by implementing a computer-based training course. This has caused some controversy, prompting families of the victims of the crashes to pen a letter to Transportation Secretary, Elaine Chao, asking to mandate simulator training before the planes return to service.
