Shares of DTS Inc. soared 12 percent Tuesday just a day after the company announced it will have to restate earnings for three quarters from last year. The Calabasas home entertainment audio technology company reported fourth-quarter results Monday. In the same announcement, it said it would restate earnings for the first, second and third quarters of last year due to an understatement of tax benefits arising from a one-time transfer to Japan and Taiwan of intellectual property licensing rights during the first quarter. The company had net income of $1.9 million (11 cents a share) for the quarter ending Dec. 31, compared with net income of $17.3 million (96 cents) in the same period a year earlier. Revenue decreased 5 percent to $35.2 million. On a pro forma basis, the company had net income of $6.2 million (34 cents a share), compared with net income of $8.3 million (46 cents) in the same period a year earlier. Analysts on average expected earnings of 32 cents on revenue of $34.3 million, according to Thomson Financial Network. The company gave no explanation as to why the pro-forma income was higher for the quarter. Shares rose as high as $34.30 before closing at $33.72, up 12 percent, on the Nasdaq.
