Analysts expect RIM will post a loss of about 47 cents per share, according to a poll from Bloomberg.
But the results could also be less dismal than some analysts have expected.
Earlier this week chief executive Thorsten Heins said that the company managed to add two million new subscribers to its services in the quarter _ a surprise to many analysts who were predicting the number of subscribers to plateau.
Some analysts have noted that even though RIM has added new customers, many of them have been in emerging markets where lower priced phones are the norm.
Cheaper phones don't add as much to the bottom line.
RIM has been pushing ahead with plans to launch its much-delayed BlackBerry 10 operating system and new smartphones sometime early next year.
