What Microchip Technology Inc told the SEC could break it.
Microchip's exposure is Asia-centric at both ends of the business. On the demand side, about 75% of fiscal 2026 net sales went to foreign customers, with China at 18% and Taiwan at 15% the two largest. On the supply side it leans on the same region — roughly 65% of sales came from chips made at outside wafer foundries (including all of its 300mm requirements), and about 67% of its assembly and test runs through its own facilities in Thailand and the Philippines. Trade policy lands directly on that map: BIS semiconductor export controls and restricted-party rules constrain who it can sell to, while escalating US-China tariffs and a new 10% U.S. baseline tariff raise its input and product costs.
6 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.
Geographic concentration
- Chinamedium
18% of fiscal 2026 net sales were made to customers in China, the single largest foreign-country exposure.
“During fiscal 2026, approximately 75% of our net sales were made to foreign customers, including 18% in China and 15% in Taiwan.”
- Taiwanmedium
15% of fiscal 2026 net sales were made to customers in Taiwan.
“During fiscal 2026, approximately 75% of our net sales were made to foreign customers, including 18% in China and 15% in Taiwan.”
- Thailand and Philippines assembly/testlow
Internal product assembly and test is concentrated in Thailand and the Philippines, performing ~67% of assembly requirements.
“We operate assembly and test facilities in Thailand and the Philippines. Approximately 67% of our assembly requirements were performed in our internal assembly facilities during each of fiscal 2026 and fiscal 2025.”

Regulatory & policy
- BIS semiconductor export controlsmedium
U.S. Department of Commerce/BIS export licensing restrictions on semiconductors and additions to restricted-party lists constrain transactions, with the 50% Affiliates Rule only temporarily suspended.
“Department of Commerce added restrictions and export license requirements to end uses and product categories previously described in the October 2022 regulation. To date, the U.S. Department of Commerce has issued a number of regulations that further restrict transactions involving semiconductors and related products.”
SEC filing →As of 2026 - US-China tariffs and global baseline tariffmedium
Escalating US-China tariffs plus a new U.S. baseline 10% tariff on almost all imported goods raise input and product costs the company may be unable to fully mitigate.
“Trade tensions between the U.S. and China, have continued to escalate from 2018 to present, and include the U.S. increasing tariffs on Chinese origin goods and China increasing tariffs on U.S. origin goods. Additionally, the U.S. has imposed a baseline 10% tariff on almost all imported goods globally.”
Supplier concentration
- third-party wafer foundriesmedium
65% of fiscal 2026 sales came from products produced at outside wafer foundries, with all 300mm wafer requirements outsourced to third parties.
“We augment our internal manufacturing capabilities by outsourcing a significant portion of our wafer production requirements to third-party wafer foundries, including all of our 300mm wafer requirements and some of our 200mm and 150mm specialty process technologies. In fiscal 2026, approximately 65% of our sales came from products that were produced at outside wafer foundries.”
