Apple is set to announce its fiscal Q3 earnings today, following a brief climb to a $5 trillion market cap. Analysts anticipate no major surprises, with revenue growth expected to be in the 14% to 17% range year-over-year. The consensus estimate for EPS is $1.88 and revenue is $108.8 billion, marking significant year-over-year increases.

While Apple has consistently exceeded earnings estimates in recent quarters, the focus for investors will be on the company's outlook regarding its new Apple Upgrade program. This initiative aims to make purchases more affordable monthly, potentially offsetting recent price hikes.

The key question is whether Apple expects the program to merely maintain sales or drive substantial new growth. This outlook is likely to significantly influence market reaction to today's earnings report, especially as it marks Tim Cook's final earnings call as CEO.
