Subaru Corp. said Friday its operating profit for the past year has halved after it suffered a string of setbacks including production delays and mounting recalls.

Japan's seventh-biggest automaker released its results hours ahead of schedule after it inadvertently uploaded its financial results on its website earlier than planned. The company initially withdrew the material, but not before social media noticed, sending its shares down more than 2 percent after the error.

The results, officially released at 10:25 a.m. instead of the scheduled 1 p.m., showed operating profit had fallen 48.5 percent to ¥195.53 billion ($1.78 billion) in the year ended in March, in line with analysts' estimates.
