Apple Q4: 46.7M iPhones, up 3% YoY from 45.5M; 10.3M iPads, up 11% YoY from 9.3M; 5.4M Macs, up 10% YoY from 4.9M; Q1 2018 revenue of $85-87B expected
Context & Ripple Effects
This Q4 print is the setup for Apple's most-watched quarter of the year: modest iPhone growth of 3% YoY to 46.7M, but an unusually aggressive $85B–$87B revenue guide that implies a much bigger holiday quarter than the units alone suggest. That gap between flat-ish volumes and a big number is the story.
The follow-through came three months later, when Apple reported 77.3M iPhones at a $796 ASP — units slightly down, revenue at the top of this very guidance range. It was also a turning point for iPad, which had been shrinking since at least 2015, when iPad sales were down 23% YoY; this quarter's 11% growth marks the line's return to expansion.
First-order effects
- Apple lands its own $85B–$87B guide, but the mechanism revealed in the next quarter's report is price, not volume — a $796 iPhone ASP against a 1% unit decline means revenue growth now comes from mix, not shipments.
Second-order effects
- With iPhone units plateauing, Wall Street's scorecard shifts from quarterly shipment counts to ASP and attach economics — the same quarter showed services revenue up 18% YoY to $8.5B, giving Apple a second growth lever that doesn't depend on selling more boxes.
Third-order effects
- If the pattern holds — and later reports like the 2026 quarters, where iPhone grew 22% YoY on revenue rather than units, suggest it does — Apple's business settles into a structure where hardware units are roughly flat while revenue per device and services carry growth, changing how every future quarter gets judged.
The trend: Apple's earnings story is migrating from unit-volume growth to pricing power and services mix, with flat-to-modest hardware shipments increasingly offset by rising revenue per device.
