1. Yahoo hacking: Shares in Yahoo (YHOO) are slated to drop Thursday after the company admitted to another hack that may have affected more than 1 billion accounts.

The breach dates back to 2013 and is thought to be separate from a massive cybersecurity incident announced in September.

The new hack threatens Verizon's (VZ) $4.8 billion deal to buy Yahoo, given the hit to Yahoo's brand.

"As we've said all along, we will continue to evaluate the situation as Yahoo continues its investigation," Verizon said in a statement Wednesday. "We will review the impact of this new development before reaching any final conclusions."

2. New food combo?: Two food giants are reportedly considering a major combo.

Shares in Oreo-maker Mondelez International (MDLZ) are surging in extended trading based on reports that Kraft Heinz (KHC) is considering a takeover. Other reports say there's no takeover in the works.

Kraft Heinz and Mondelez declined to comment.

A takeover would be unusual because Mondelez was spun off from Kraft back in late 2012.
