The Walt Disney Company has agreed to acquire Marvel Entertainment in a stock and cash transaction, the companies announced today.

Based on the closing price of Disney stock on Friday, August 28, the transaction value is $50 per Marvel share or approximately $4 billion.

Under the deal, Disney will acquire ownership of Marvel including its more than 5,000 Marvel characters.

This new deal, however, does not affect the current movie deals that Marvel has set up with Sony and Paramount. Those deals are still in effect, but once they expire, Disney hopes to be the sole distributor of any future Marvel films.
