Yum’s comments on China, its No. 1 market for revenue and profit, sent company shares up 4.5 percent to $84.52 in extended trading. Yum said China sales at established restaurants fell less than expected for the first quarter as it works to recover from allegations of improper meat handling at OSI Group’s Shanghai Husi Food Co Ltd, which was a small supplier to Yum but a key supplier to rival McDonald’s Corp. Both companies immediately stopped using the supplier. Yum is making “continued progress” in China, Chief Executive Greg Creed said in a statement.
