Apple's hardware business has been mature for the better part of a decade. iPhone unit volumes have been roughly flat at 220-240 million annually since 2018. Mac and iPad revenue has been cyclical but has not contributed to franchise growth. The Apple Watch and AirPods franchises were initially growth contributors but have plateaued.
The entire compounding story since 2020 has rested on services. Subscription revenue from iCloud, Apple Music, Apple TV+, App Store fee economics, and the financial services and advertising businesses all grew at premium rates. Crucially, services gross margin was structurally above 60%, well above the hardware franchise's 35-40% gross margin. As services mix expanded, consolidated gross margin expanded, and the multiple expanded.
The expansion was supported by App Store economics specifically. Apple's commission rates of 15-30% on most digital transactions in the App Store created a structurally high-margin revenue stream. The growth in subscription apps, gaming microtransactions, and digital content all flowed through that high-margin channel.
The regulatory pressure on App Store economics has been the bear talking point for two years. The EU Digital Markets Act has forced changes in third-party app installation. The US App Store class action settlement has compressed the developer fee structure on smaller revenue tiers. The cumulative impact has been measurable and is starting to show.
