Check out which companies are making headlines after the bell on Wednesday:

Shares of Apogee Enterprises shot up about 6 percent in after-hours trading after the firm easily beat quarterly earnings and revenue expectations. The firm reported earnings of 77 cents per share on revenue of $279 million.

Analysts expected the manufacturing firm to post profits of 67 cents per share on sales of $268.1 million. "The strength we are seeing in our non-residential construction end markets is evident in the results from our architectural segments. All three architectural segments grew revenues and operating income, with operating margins all increasing more than 200 basis points," CEO Joseph Puishys said.

Shares of Wells Fargo fell about 0.1 percent after Dow Jones reported federal prosecutors in New York and California are investigating the firm. The banking giant has been hit hard by a fake account scandal that sent its stock lower recently.

Social media giant Twitter saw its stock climb more after the bell, rising more than 0.5 percent after announcing it will launch its app on Apple TV and other platforms where viewers can stream NFL games.

The FDA recommended removing a serious warning on Pfizer's drug Chantix, which is used to help people quit smoking. Investors were betting big on the drug when Pfizer launched it in 2006, but reports of mental health problems in users prompted the FDA to impose the black box warning three years later. That said, Pfizer shares were unchanged in after-hours.

Shares of Herbalife continued to climb in after-hours trade, rising 1 percent on the heels of activist investor Carl Icahn's remarks. At the Delivering Alpha conference presented by CNBC and Institutional Investor, Icahn said he is seeking permission to be able to own up to 50 percent.
