Shares of Tempur Sealy International Inc. rose 4.4% in premarket trade Thursday, after the mattress maker missed profit expectations, amid declining gross margin, but beat revenue expectations for the first time in five quarters. Net income fell to $23.1 million, or 42 cents a share, from $33.9 million, or 62 cents a share, in the same period a year ago. Adjusted earnings per share of 42 cents was below the FactSet consensus of 48 cents. revenue declined 10% to $648.0 million, but beat the FactSet consensus of $634.3 million, as a slight miss in North America sales was offset by better-than-expected international sales. Gross margin declined 0.9 percentage points, due primarily to commodity cost inflation, fixed cost deleverage on lower unit volume and unfavorable brand mix, while international gross margin slipped 0.1 percentage points. The company affirmed its 2018 financial guidance. The stock had tumbled 29.2% year to date through Wednesday, while the S&P 500 eased 1.4%.
