SAN FRANCISCO, Jan 7 (Reuters) - Barnes & Noble Inc (BKS.N) cut its third-quarter earnings forecast on Thursday, citing lower-than-expected holiday sales, but the U.S. bookseller said it expected its stores to be fully stocked with its Nook electronic reader in the coming months.
"Orders for Nook remained strong throughout the holiday season, and, in fact, accelerated after we announced that we had sold out our initial supply," CEO Steve Riggio said in a statement.
"Demand remains strong in the new year and greater than our supply, however, we expect production to catch up with demand and be fully stocked in our stores in the next few months."
Barnes & Noble said for the nine-week holiday period that ended Jan. 2, sales at its namesake stores fell 5 percent to $1.1 billion, while same-store sales were down 5.4 percent.
Sales at barnesandnoble.com rose 17 percent to $134 million. The online sales include Nook revenue recognized since the product began shipping after the U.S. Thanksgiving holiday, it said.
The retailer now expects third-quarter earnings of $1.20 to $1.40 per share, compared with a previous forecast for $1.30 to $1.50 per share. Analysts, on average, were expecting earnings of $1.40 per share, according to Thomson Reuters I/B/E/S.
Barnes & Noble's shares fell 1.4 percent, or 28 cents, to $18.92 in early trading. (Reporting by Nicole Maestri, editing by Maureen Bavdek)
