Investing.com — Apple Inc. (NASDAQ:AAPL) stock pared gains Wednesday afternoon but remained higher by 0.9% following reports that the tech giant’s ambitious Siri virtual assistant upgrade is facing development challenges.

The company’s latest attempt to revamp Siri has encountered testing difficulties in recent weeks, potentially delaying several highly anticipated features. Apple had initially planned to include the new capabilities in iOS 26.4, an operating system update scheduled for March. However, according to a report from Bloomberg News, citing people familiar with the matter, the company is now working to distribute these features across future updates.

This development could push back the release of at least some features until iOS 26.5, expected in May, or even iOS 27, slated for September. The setbacks represent another chapter in Apple’s extended effort to modernize Siri, which was first announced in June 2024.

Despite the reported delays, investor reaction remained relatively muted. Apple shares had traded up 2% earlier in the session before moderating gains in afternoon trading.
