Southwest boosts guidance, Dish close to major deal, CBS may get back together with Viacom: Companies to watch

Here are the companies Yahoo Finance is watching today.

Southwest Airlines (LUV) is raising its guidance, even as the grounding of those Boeing 737 Max jets weighs on capacity. It now expects revenue per seat mile to rise between 6.5% and 7.5% this quarter. However, it's removing all Max flights through September 2 because the timeline for those jets returning to the air remains uncertain.

Another name has emerged as the potential buyer of some assets from Sprint (S) and T-Mobile (TMUS). Dish Network (DISH) is reportedly close to a $6 billion dollar deal to buy Boost mobile and some wireless spectrum from the two carriers. It's part of an agreement with the U.S. Justice Department to clear a Sprint-T-Mobile merger.

CBS (CBS) and Viacom (VIA) could again be getting back together. The Wall Street Journal said the companies have had preliminary talks about a merger, and CBS is preparing to make an offer in the coming weeks. Both are controlled by Sumner Redstone's National Amusements. If this sounds familiar, Viacom bought CBS back in 2000, before they were split up in 2006.

PG&E (PCG) just agreed to a $1 billion dollar deal to compensate more than a dozen California cities for the losses caused by their equipment during the deadly wildfires. The company estimates it could face more than $30 billion dollars in costs for the fires in 2017 and 2018. The agreement is the first major settlement for PG&E since it sought bankruptcy protection earlier this year.

You can now play video games inside your Tesla's (TSLA). The automaker just debuted Tesla Arcade — a game hub found across its line of electric cars. One of the games included is Vector Unit's “Beach Buggy Racing 2,” which is available on Android phones and tablets, and uses the car’s steering wheel as a controller while in park.
