Ralph Lauren Corp.’s quarterly profit rose 35 percent as it benefited from lower cotton prices and cost controls. But the stock fell because revenue was below expectations. Net income was $127.2 million, or $1.37 per share. Revenue rose a slim 1.2 percent to $1.64 billion. Analysts had expected earnings of $1.31 per share on revenue of $1.7 billion. The company projects revenue to rise 4 to 7 percent for the full year.
