What Advanced Energy Industries, Inc. told the SEC could break it.
Advanced Energy's disclosures cluster on two kinds of concentration. Its revenue leans on a few large customers — three individually accounted for about 23%, 19% and 12% of 2025 revenue — so losing one would hurt materially. The other is geographic: its manufacturing is mainly in the Asia-Pacific region and 70% of revenue came from customers outside the U.S., which ties it to APAC supply, currency and geopolitical risk (it closed its Zhongshan, China site in 2025 while expanding in the Philippines, Mexico and Thailand). Reinforcing both, it flags U.S. export restrictions to China and Section 301/232 tariffs that raised its costs and softened China demand, plus key parts available only from sole or limited suppliers.
4 self-disclosed vulnerabilities, pulled from its own filings — each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Customer concentration
- three customers 23% / 19% / 12% of revenuehigh
Advanced Energy's revenue is concentrated: three customers individually accounted for ~23%, 19% and 12% of 2025 revenue (and 26%/10%/20% of accounts receivable); loss of a large customer would materially hurt results.
“customers accounted for 23 %, 19 %, and 12 % of our total revenue, respectively. During the year ended December 31, 2024, two customers accounted for 26 % and 11 % of our total revenue, respectively.”
SEC filing →As of 2026
Geographic concentration
- manufacturing mainly in Asia-Pacific; 70% non-US revenuemedium
Advanced Energy's manufacturing is concentrated in the Asia-Pacific region and 70% of 2025 revenue came from customers outside the U.S., exposing it to APAC supply, FX and geopolitical risk (it shut its Zhongshan, China site in 2025 and is expanding in the Philippines, Mexico and Thailand).
“Our manufacturing facilities are located across the globe (mainly in the Asia-Pacific region), and revenue from customers outside the United States represented 70% of our total revenue during the year ended December 31, 2025.”
Sole-source dependency
- sole/limited-source key partsmedium
Some key parts used in Advanced Energy's products can only be obtained from a sole supplier or a limited group of suppliers, creating production-continuity risk.
“some key parts may only be obtained from a sole supplier or a limited group of suppliers.”

Regulatory & policy
- US-China export restrictions & Section 301/232 tariffslow
U.S. export restrictions to China and Section 301/232 tariffs raised Advanced Energy's costs in 2025 and dampened China semiconductor demand; escalating US-China trade tensions threaten its APAC-centric supply chain and sales.
“lower trailing-edge logic demand due to capacity underutilization, particularly in China, U.S. export restrictions to China, and the impact of tariffs.”
