Apple Dependency Endures While PC Diversification Meets Supply Friction
- Apple accounted for 91% of fiscal 2026 net sales, an increase from 89% the prior year.
- A capacity agreement with GlobalFoundries secures US wafer supply for 2027 and 2028.
- New analog components for smart meters will begin sampling in the September quarter.
- Efforts to expand into PCs face near-term delays from industry component constraints.
A tight grip from one big customer
Cirrus Logic is best understood as a highly dependent Apple supplier. The company wins custom chip work in areas like smartphone audio and high-performance mixed-signal chips, which manage real-world signals such as power, sound, and sensing.
The fiscal 2026 results showed Apple at 91% of net sales for the year. This dependency is not fading. The bull case is supported by a smart power IC for FaceID and a new capacity agreement with GlobalFoundries through 2028, pointing to a deep supply chain link.
Efforts to diversify remain mixed. Cirrus recently taped out a new component family for smart meters, expecting to sample them in the September quarter. However, PC expansion has slowed due to component shortages and delays in new model introductions.
The bear case leads the risk list. If Apple cuts orders, pushes price lower, or builds similar chips internally, Cirrus would feel it fast. A real diversification story needs one clear proof point, which is a lower Apple sales share in future filings.
Custom chips without owning fabs
Cirrus is a fabless chip company. It designs chips but relies on outside manufacturers to make them. Its job is to win design slots in devices, then ship parts through contract manufacturers when those devices are built.
The company reports one operating segment, but it details sales for two product lines: Audio and High-Performance Mixed-Signal, or HPMS. Audio includes parts like boosted amplifiers. HPMS includes chips that handle power, timing, and other control needs.
This model can be attractive when a customer keeps using Cirrus parts across product generations, which supports strong margins. But the custom work traps the company inside one customer's product roadmap.
Management wants growth from three places: defending smartphone audio, adding more HPMS content in smartphones, and moving into new markets like smart meters and PCs. So far, the Apple concentration shows the first two still dominate.
Where the chips fit
Audio products
Audio is the larger product line. Fiscal 2026 Audio sales were $1.16 billion, helped by smartphone demand.
High-Performance Mixed-Signal products
HPMS was $837.4 million in fiscal 2026 sales and grew 10% from fiscal 2025. These chips handle areas like power and battery control.
Smart power IC for FaceID
This is a new disclosed design area tied to the largest customer's FaceID system. The key unknown is how much revenue and margin it can add.
PC amplifiers and codecs
Cirrus is pushing into PCs, but progress is facing near-term headwinds from industry component shortages and delayed model introductions.
Smart meter analog components
The company recently taped out a new family of high-performance analog front-end components targeting smart meters.
Two product lines, one giant customer
Mix is based on fiscal 2026 product-line sales from the FY2026 10-K. Cirrus reports one operating segment, and Apple was 91% of total net sales for the year.
What could break the story
Apple order shock
High impact · High oddsApple was 91% of fiscal 2026 net sales. A cut in orders, a weaker device cycle, or a shift away from features that use Cirrus chips would hit revenue quickly. This is the main risk, not a side issue.
In-sourcing or second sourcing
High impact · Medium oddsA large customer can choose to build similar chips itself or add another supplier. Even if Cirrus keeps the slot, the threat can pressure price and margin.
Diversification that stays too small
Medium impact · High oddsCirrus is working in PCs, automotive, and smart meters. But the Apple share has risen from 87% to 91% over three fiscal years. If new markets stay small, the concentration risk remains.
PC market headwinds
Medium impact · High oddsThe company noted that memory and component shortages are causing delays in new PC model introductions. This slows down one of the main avenues for diversification.
In one breath
Why is Cirrus Logic so tied to Apple?
Cirrus sells custom chips that go into major consumer devices, and Apple is by far its largest end customer. In fiscal 2026, Apple represented 91% of total net sales through multiple contract manufacturers.
What does HPMS mean for Cirrus Logic?
HPMS means High-Performance Mixed-Signal. These chips manage real-world signals like power, timing, battery, and sensing functions, and HPMS grew faster than Audio in fiscal 2026.
Is Cirrus Logic diversifying away from smartphones?
It is trying to. Management points to PCs and new smart meter components, but the customer concentration data shows diversification is not yet material to the total company.
