Four out of the eight members of Sequential Brands Group’s board of directors have resigned as required by the extension until Apr. 19, 2021 of a credit agreement with Wilmington Trust and other lenders. The remaining members on the board represent mostly lenders such as KKR and Blackstone Group. The struggling New York-based company, which has been evaluating strategic alternatives, plans to file its 2020 results by Apr. 15 at the latest. Sequential’s roster of brands includes Avia, And1 and Heelys, among others.
