Apple Inc.’s next earnings report is not due until mid-October, but expectations for another blockbuster quarter are already building.

FactSet projects that the tech giant will be the main positive contributor for tech earnings in the third quarter, even though new iPhones won’t be released until very late in the quarter.

“As of today, if Apple reported actual EPS equal to or above the mean EPS estimate, it would mark the 5th consecutive quarter that Apple has been the largest contributor to year-over-year earnings for the information technology sector,” said John Butters, senior earnings analyst at FactSet.

Apple AAPL, +1.57% is forecast to post earnings of $1.87 a share on revenue of $50.82 billion when it reports its fiscal fourth-quarter results on Oct. 19.

Without Apple, tech earnings are likely to drop 5.9% year-on-year in the third quarter, compared with a decline of 0.4% when Apple is included, FactSet projects.

Strong rise in iPhone sales have supported Apple’s robust results for the past year, even as demand for other products like the iPad and iPod declines.

“The iPhone product segment has reported revenue growth in excess of 50% in the previous three quarters, and is projected to report revenue growth of 31% in third quarter,” Butters said.

It not clear, however, whether Apple can continue to count on steady iPhone demand, with sales projected to drop 1% from last year’s huge fourth quarter.

“As a result, the magnitude of Apple’s contribution to year-over-year earnings growth for the information technology sector is expected to be much smaller in fourth quarter relative to recent quarters,” Butters said.

The Cupertino, Calif.-based company on Wednesday unveiled a slew of devices, including an iPhone 6s, an upgraded Apple TV, and the iPad Pro. However, the iPhone 6S sales do not launch until very late in the quarter, on Sept. 25, and the other new products will begin selling in Apple’s fiscal first quarter.

Shares of Apple rallied 4.5% during the week to close Friday at $114.21, but the stock is off more than 15% from its 52-week high of $134.54 in late April.
