Apple Tie Deepens, Diversification Still Missing
- Apple was 91% of fiscal 2026 net sales, up from 89% in fiscal 2025 and 87% in fiscal 2024.
- Fiscal 2026 sales rose 5% to $2.00 billion, with HPMS growing faster than Audio.
- The bull case is more Apple content per device, including a new smart power IC for FaceID.
- The bear case is simple: one customer has huge power over price, volume, and design choices.
- PC, automotive, industrial, and general market work matters, but it has not changed the revenue mix yet.
A strong grip, one big hand
Cirrus Logic is best understood as a highly tied Apple supplier. That tie is valuable. Cirrus keeps winning 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 10-K made the main debate clearer. Apple was 91% of net sales for the year. That is lower than the 94% level reported in the third quarter, but still higher than 89% in fiscal 2025 and 87% in fiscal 2024. The dependency is not fading.
The bull case got fresh support. Cirrus disclosed work on a smart power IC for its largest customer's FaceID system and joined that customer's American Manufacturing Program with GlobalFoundries in Malta, New York. Those details point to a deeper design and supply chain link, not a loose parts deal.
The bear case still leads the risk list. If Apple cuts orders, pushes price lower, builds similar chips inside the company, or adds another supplier, Cirrus could feel it fast. A real diversification story needs one clear proof point: a lower Apple sales share in future filings.
Custom chips without owning fabs
Cirrus is a fabless chip company. That means 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 gives sales detail for two product lines: Audio and High-Performance Mixed-Signal, or HPMS. Audio includes parts like boosted amplifiers and smart codecs. HPMS includes chips that handle power, timing, battery, camera, and other control needs.
This model can be attractive when a customer keeps using Cirrus parts across product generations. Design wins can repeat, and fiscal 2026 gross margin was 52.8%. But the same custom work can trap 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 PCs, automotive, industrial, imaging, and professional audio. So far, Apple concentration says 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 and higher PC sales.
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, battery, camera control, and other real-world signals.
Custom boosted amplifiers
These chips help small device speakers sound louder and cleaner. Cirrus cited demand for its latest custom boosted amplifier in smartphones.
Smart codecs
A codec converts sound between digital and analog forms. Cirrus pointed to demand for its 22-nanometer smart codec in fiscal 2026.
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 says it gained share across PC segments and introduced products for more platforms, including AI-enabled PCs. The open question is whether PCs can become large enough to lower Apple concentration.
Two product lines, one customer shadow
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. Custom design work helps lock Cirrus in, but it also ties Cirrus to the customer's choices.
Diversification that stays too small
Medium impact · High oddsCirrus is working in PCs, automotive, industrial, imaging, and professional audio. That sounds broad, but the sales mix still points back to one customer. The Apple share has risen from 87% to 89% to 91% over three fiscal years.
FaceID power chip ramp risk
Medium impact · Medium oddsThe new smart power IC for FaceID supports the bull case, but the company has not quantified its revenue or margin profile. A delayed ramp, smaller content value, or weaker margin would make the win less useful than it sounds.
Supply chain change costs
Medium impact · Medium oddsCustomers want more geographic diversity in supply chains. Cirrus joined an American Manufacturing Program and is working with GlobalFoundries in Malta, New York. That may improve resilience, but new process work can add cost or execution risk.
Engineering talent squeeze
Medium impact · Medium oddsCirrus disclosed risk from changes to the H-1B visa process. The company said rules that favor higher-paid roles may hurt employers seeking early-career or entry-level engineers. For a chip design company, access to engineers matters.
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, camera, 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, automotive, industrial, imaging, and professional audio, but the customer concentration data shows diversification is not yet material to the total company.
What is the main thing to watch next?
Watch the Apple sales percentage in quarterly filings. A real drop would be the clearest sign that non-Apple or non-smartphone growth is starting to matter.
