Soft domestic as well as overseas CD sales hurt Warner Music Group Corp.’s third-quarter earnings, sending shares down nearly 9 percent.

Warner reported a third quarter loss of $17 million (minus12 cents per share), worse that the $14 million loss (minus 10 cents) the company reported for the same period a year earlier. Warner said that excluding one-time items related to corporate restructuring and a settlement, the loss was $29 million (minus 20 cents per share). Wall Street was expecting a loss of 14 cents per share, according to Thomson Financial.

Revenue for the New York-based record label, which has significant offices in Burbank, also dropped 2 percent to $804 million, missing analysts’ expectations of $836 million.

“This proved to be a more challenging quarter industry-wide, as the difficult global music environment persisted,” Edgar Bronfman Jr., Warner’s chairman and chief executive, said during a conference call.

The record label said that digital revenue increased 29 percent to $119 million while revenue from recorded music fell 4 percent to $653 million. Domestic recorded music sales declined 1 percent to $345 million, while international recorded music sales fell 7 percent to $308 million.

For the nine-month period ended June 30, Warner posted a net loss of $26 million (minus 18 cents per share), compared to net income of $48 million (34 cents) for the same period a year earlier. Revenue for the nine-month period fell 5 percent to $2.5 billion.

Shares in Warner fell 8.8 percent to, or 97 cents, to $10.06 in afternoon trading Tuesday on the New York Stock Exchange.
