Utility giant PG&E (PCG) could soon be making some major changes. The Wall Street Journal says the company is close to naming a new CEO, and adding a new slate of independent board members.

The global payment platform, Worldpay (WP), is getting bought up. Fidelity National Information Services is acquiring Worldpay in a $43 billion dollar deal.

Southwest Airlines (LUV) and its mechanics union could be reaching a deal to end their long-running labor dispute. The five year contract, which still needs to be voted on, would give mechanics a 20% raise and about $160 million dollars in bonuses. The agreement comes after six years of ongoing negotiations.
