What Aviat Networks, Inc. told the SEC could break it.
Most of what Aviat flagged traces to a thin, geographically concentrated chip supply. It buys the ASICs and MMICs at the heart of its microwave radios from a single source (at a volume discount) and limits suppliers for tooled metal fabrications, so a delay from those sole or limited sources could push out or lose sales. That semiconductor supply is concentrated in Taiwan with little availability elsewhere, meaning a Taiwan–China military conflict could interrupt it, and the components it imports plus the U.S.-made products it ships into China sit on both sides of U.S.–China tariffs. On the demand side, a significant share of revenue may come from a limited number of customers — mobile operators — whose loss would materially affect the business.

In its own words
What could break it.
Sole-source dependency
- single-source ASICs and MMICs (and limited-supplier metal fabrications)high
Aviat procures ASICs and MMICs (key integrated circuits for its microwave radios) from a single source at volume discount and limits suppliers for owned-tooling metal fabrications; a delay from these sole/limited sources could defer or lose sales.
“and ASIC's and MMICs (types of integrated circuit used in manufacturing microwave radios), which we procure at volume discount from a single source.”
SEC filing →As of 2025
Customer concentration
- revenue from a limited number of customersmedium
A significant amount of Aviat's revenue may come from a limited number of customers (mobile operators), so the termination of any of these customer relationships could materially affect its business.
“Because a significant amount of our revenue may come from a limited number of customers”
SEC filing →As of 2025
Geographic concentration
- semiconductor supply concentrated in Taiwan (Taiwan-China conflict risk)medium
Certain of Aviat's semiconductor supply is concentrated in Taiwan with little availability elsewhere, so a military conflict between Taiwan and China could interrupt its component supply.
“certain semiconductor supply is concentrated in Taiwan, with little to no availability in other geographies. As such, any military conflict between Taiwan and China could interrupt supply.”
Regulatory & policy
- U.S.-China tariffs on imported components and U.S.-made productsmedium
Some components Aviat imports are subject to U.S. tariffs, and certain of its U.S.-manufactured products are subject to Chinese retaliatory tariffs on imports into China, raising cost and trade-policy uncertainty.
“Certain of our products manufactured in our U.S. operations are subject to the tariffs imposed on imports into China from the United States.”
