What Skyworks Solutions, Inc. told the SEC could break it.

Skyworks is extremely concentrated in Apple, which (via distributors, contract manufacturers and direct sales) was 67% of FY2025 net revenue, and its three largest receivables balances were 82% of aggregate gross accounts receivable.

“During fiscal 2025, fiscal 2024, and fiscal 2023, Apple, through sales to multiple distributors, contract manufacturers, and direct sales for multiple applications including smartphones, tablets, desktop, and notebook computers, watches and other devices, in the aggregate accounted for 67 %, 69 %, and 66 % of the Company's net revenue, respectively.”

China's 2025 countermeasures have impacted the availability and cost of materials critical to Skyworks' RF semiconductors — gallium, germanium, antimony, tungsten, molybdenum, scandium and other rare earth metals/critical minerals.

“the countermeasures announced in 2025, has impacted and could continue directly or indirectly adversely impacting our manufacturing costs, the availability and cost of materials, including gallium, germanium, antimony, tungsten, molybdenum, scandium, and other rare earth metals/critical minerals, and the sales of our products in China, the United States and elsewhere.”

Skyworks derives significant revenue from Asia-Pacific and Europe, runs its own wafer fab in Osaka, Japan plus packaging/test in Singapore and Mexicali, Mexico, and relies on Asia-Pacific foundries/OSATs — concentrating operations and customers in regions exposed to China business and trade risk.

“We derive significant revenues from customers located outside the United States, primarily in countries located in the Asia-Pacific region and Europe. We have suppliers located outside the United States, including third-party packaging, assembly, and test facilities and semiconductor foundries located in the Asia-Pacific region. We also operate our own wafer processing facilities in Osaka, Japan, as well as packaging, assembly, and test facilities in Singapore and in Mexicali, Mexico.”

2025 U.S. tariffs on numerous trading partners and sectors, plus Chinese countermeasures, have impacted and could further raise Skyworks' operating costs and depress demand for its and its customers' products.

“the imposition of or changes to tariffs, including the tariffs announced by the United States in 2025 with respect to numerous global trading partners and sectors, and any retaliatory tariffs or measures by any such trading partners, including countermeasures by China, have impacted and could further negatively impact trade between, or increase the cost of operating in, or increase the cost of or negatively impact the demand for, our products or our customers' products in the countries”

Although Skyworks generally avoids single-source supply, it is currently dependent on a limited number of sole-source suppliers for certain components and services, and losing them could materially harm the business until alternates are qualified.

“While we do not typically rely on a single source of supply for our raw materials, we are currently dependent on a limited number of sole-source suppliers and in the future could become dependent on additional sole-source suppliers. If we were to lose these sole sources of supply, for any reason, a material adverse effect on our business could result until an alternate source is obtained.”
