Iconix Brand Group reports a 42 percent jump in sales to $71.7 million for the first quarter, with an equally impressive leap of 53 percent in net income to $27.0 million. It has upped its forecast for sales for the fiscal year to $305-315 million, over the previous guidance of $260-270 million. This would include organic growth of about 7 percent, plus $35 million to $40 million related to its new acquisition of the Peanuts brand, just completed a couple of weeks ago. It has bought the line, which includes characters such as Charlie Brown and Snoopy, in partnership with the family of the late Charles M. Schulz, creator of the comic strip. Iconix will hold an 80 percent stake in the subsidiary created for the purchase, and the Schulzes will have 20 percent. The purchase, from United Features Syndicate and the E.W. Scripps Company, also includes United Media Licensing, which is in charge of such characters as Dilbert and Fancy Nancy. The Peanuts brand is licensed in more than 40 countries and generates annual retail sales of more than $2 billion. Iconix paid $175 million in the deal from its $214 million in cash.
