SAN FRANCISCO — Apple’s next iPhone is coming. But when, exactly? 

Buried in Apple’s third-quarter results late Tuesday may be details about the availability of its redesigned iPhone 8, expected to be announced in early September. 

If revenue outlook is on the high end, it would suggest the smartphone will be on sale later that month. If not, it would confirm fears the product’s OLED screens, an improved display that would allow for sharper colors and better battery life, are in short supply, and consumers won’t be able to get their hands on the new phone until October or later, cautions RBC Capital Markets analyst Amit Daryanani in a report.

Whispers are a new, features-packed iPhone could spur a super-cycle of sales that send Apple’s shares as high as $170, according to a recent report from investment firm UBS. The company’s market value might soar to a record $1 trillion.

But Apple’s path to smartphone gold comes with a big if — as in, when does the long-rumored iPhone 8 go on sale?

Two analyst reports issued last weekunderline growing concerns about the initial availability of iPhone 8 and two other new iPhones, which are said to be akin to an iPhone 7S and 7S Plus.

“Based on incremental supply chain data points that suggest a more pronounced OLED iPhone delay, we think the flagship device may not see initial shipments until October (vs. mid/late September for historical new iPhone launches) with volume shipments not occurring until the November/December time frame,”analyst Daryanani said in a report.

Short-term concerns about the 10th-anniversary iPhone were underscored in a note to clients by BMO Capital Markets. Analyst Tim Long lowered his estimates for Apple’s September quarter guidance to $43.5 billion to $45.5 billion “owing to our view that initial shipment volumes of the premium iPhone Pro will be limited.”

As iPhone 8 production steadily increases, BMO analyst Long says he will adjust his fiscal 2018 iPhone “unit and average selling price estimates higher.”

Apple historically announces new iPhones in early September, so they can be sold during the quarter ending in September and count toward the company’s third quarter. For example, the company sold 13 million iPhones in the first weekend iPhone 6S and 6S Plus were available in the fourth week of September 2015.
