Home decor retailer At Home Group Inc. shares fell 24% in premarket trade Thursday, after the company missed earnings estimates for its fiscal first quarter and offered guidance that lagged expectations. Plano, Texas-based At Home Group said it had net income of $13.9 million, or 21 cents a share, in the quarter, down from $18.4 millin, or 28 cents a share, in the year-earlier period. Adjusted per-share earnings came to 3 cents, below the 8 cents FactSet consensus. Sales rose 19.6% to $306.3 million from $256.2 million, also below the FactSet consensus of $360 million. Same-store sales fell 0.8%, while FactSet expected a 0.4% gain. "It was a challenging first quarter as we faced unusually adverse weather across a majority of our markets, resulting in comparable store sales below our expectations," Chief Executive Lee Bird said in a statement. The retailer has marked down inventory to sell through the product at lower-than-expected margins, and head into the fall in a cleaner position, he said. The company is now expecting fiscal 2020 same-store sales to be down 1% to up 1%. Adjusted EPS is expected to range from 67 cents to 74 cents, well below the $1.03 FactSet consensus. Shares have fallen 6% in the year through Wednesday, while the S&P 500 has gained 13%.
