Threats made by hackers prompted Sony to initially cancel its theatrical release. It was eventually screened in select art house cinemas, and released on the Internet and via cable TV providers.
Washington has blamed North Korea for the hack -- a claim Pyongyang has denied while still strongly condemning the film, which features a fictional plot to assassinate leader Kim Jon-un.
On Wednesday, Sony also said third-quarter revenue from image sensors and its PlayStation games business picked up, but sales were down in the movie and television production business.
Restructuring costs in the quarter were down by a third from a year ago, it said.
For the nine months to December, Sony estimated it had a net loss of 20.1 billion yen, reversing 9.9 billion yen profit a year earlier.
Sony shares closed 2.65% higher at 2,769.0 yen in Tokyo before the results were released.
