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

Shares of Mondelez International spiked as much as 12 percent in extended trade Wednesday after a report surfaced that Kraft-Heinz was planning to acquire the snack giant. Bloomberg News reported the news, citing Bilanz, a Swiss economic magazine.

But the cookie maker pared its gains and was up less than 6 percent after Reuters reported, citing sources, that Mondelez had not heard from Kraft-Heinz. Both companies declined to comment to CNBC. Kraft-Heinz shares were up more than 3 percent after the bell.

Yahoo fell nearly 2 percent in extended trade after announcing that more than 1 billion user accounts were compromised in August 2013. In November, law enforcement provided Yahoo with data files that a third party claimed were Yahoo data. Those files were later verified by Yahoo and outside forensic experts. Separately, the company said the data breach it disclosed in September — affecting about half a billion users — is likely separate from this data breach.

Verizon, which is expected to close its deal with Yahoo in the first quarter of 2017, told CNBC it will "evaluate the situation as Yahoo continues its investigation."

Pier 1 Imports shares were up more than 16 percent in extended trade after the retailer reported earnings and raised its full-year financial guidance. The company reported adjusted earnings of 22 cents a share on revenues of $475.9 million.

Shares of Apogee Enterprises were up more than 2 percent after the bell, following its earnings report. The manufacturing company reported earnings of 78 cents a share on revenues of $274.1 million. It also raised its earnings per share outlook for 2017 by 5 cents to a range from $2.85 to $2.95, saying it expects to increase capabilities and production.
