Crocs reported third-quarter earnings on Thursday that beat estimates, and the casual-footwear maker forecast sales gains this year and next even as it navigates a mangled global supply chain. The clog maker reported a month after announcing an accelerated buyback program, and as it seeks longer-term growth in nations like China and tires to broaden its footwear offerings. Crocs earned $2.47 a share, more than double a year ago, beating estimates for $1.87.
