Check out the companies making headlines after the bell Monday:
Alcoa shares jumped in after-hours trading Monday after the company reported mixed quarterly results. The metals and mining company kicked off earnings season with fourth-quarter earnings of 4 cents per share, topping analyst expectations. But it fell just short of predictions on revenue, coming in at $5.25 billion. Later this year, Alcoa plans to separate into two publicly traded companies, one housing its legacy aluminum and smelting operations and the other its higher-growth materials segment.
