Overall revenue rose 12 percent to $114.5 billion. The Mac business grew 24 percent to $10.79 billion and services, which spans App Store commissions and subscriptions such as Apple TV and Apple Music, reached $31.57 billion. iPad was the outlier, with revenue down 10 percent to $6.23 billion.

Rising memory costs are part of the picture. CEO John Ternus told CNBC the company saw higher memory costs compared with the June quarter, partly offset by carrying inventory and lower costs on non-memory components. Like other device makers, Apple has raised prices across its products in response.

The services side carries some caveats. CFO Kevan Parekh said App Store performance in the September quarter was similar to the prior year, with a record number of paid subscriptions and double-digit growth for third-party apps, but he flagged headwinds in mobile gaming that he expects to continue into the summer quarter. He guided services growth of 8 to 9 percent for the December quarter, citing third-party licensing and foreign exchange as the main drags.

Parekh also hinted at where growth might come from, saying AI offers a compelling upgrade reason for customers and that there are opportunities across third-party apps and partnerships as well as first-party efforts. He did not elaborate, though Reuters reported that investors are wondering whether Apple could take a cut of third-party AI agents distributed through the App Store. Regulatory changes have already cut into App Store commissions in some markets, and third-party estimates in August suggested an 18 percent drop in US commission revenue.
