As I first reported yesterday, NYC-based kids media company 4Kids Entertainment has put itself up for sale, and today the company has announced it officially. It has hired Montgomery & Co. to help it evaluate options, it said in a release. “Given recent developments in our business and in the current macroeconomic environment, we have decided to retain a financial advisor…[will] carefully weigh all viable strategic alternatives that may be identified by its financial advisor potentially including, but not limited to, asset sales, alliances with strategic partners, and/or a sale of the company through a merger or other corporate transaction.” More background in my post from yesterday.
