What L3HARRIS TECHNOLOGIES, INC. /DE/ told the SEC could break it.
L3Harris's defining exposure is its dependence on a single customer: 75% of fiscal 2025 revenue came from U.S. Government customers (directly, through prime contractors, or via U.S.-funded foreign military sales), with no other customer over 5% — tying it tightly to federal defense appropriations. Its supply chain carries geopolitical risk too: some materials were previously sourced from areas now under sanctions (specialty metals from Russia) and certain equipment is currently sourced from China or other at-risk areas. And it depends on single suppliers for certain components and a limited number of certified microelectronics suppliers, where it has little negotiating leverage and qualifying alternatives is difficult and costly.
3 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
- U.S. Government — 75% of FY2025 revenue; no other customer >5%high
L3Harris derived 75% of FY2025 revenue from U.S. Government customers (directly or through prime contractors, including foreign military sales funded by the U.S. Government); no other single customer accounted for more than 5% of revenue, creating extreme concentration on federal defense appropriations.
“In fiscal 2025, the percentage of our revenue that was derived from sales to U.S. Government customers, whether directly or through prime contractors, including foreign military sales funded through the U.S. Government, was 75% and no other customer accounted for more than 5% of our revenue.”

Regulatory & policy
- Russia/China sanctions — specialty metals from Russia (prior) and certain equipment from China currently sourced from at-risk areasmedium
L3Harris discloses that certain materials in its supply chain were previously sourced from Russia (specialty metals, now under sanctions) and that certain equipment is currently sourced from China or areas at risk of additional trade restrictions, creating ongoing supply chain vulnerability to geopolitical sanctions.
“some materials and components in our supply chain have previously been sourced from areas now under sanctions or other trade restrictions, such as specialty metals from Russia and certain equipment from China, or are currently sourced from areas which are at risk of sanctions or other trade restrictive actions, not just by the United States but by other nations or groups, such as the European Union.”

Sole-source dependency
- unnamed single-supplier components; limited number of certified microelectronics suppliersmedium
L3Harris depends on single suppliers for certain components and relies on a limited number of certified microelectronics suppliers; the company has limited negotiating leverage with sole-source suppliers and qualifying alternate sources is difficult and costly.
“In some instances, we depend upon a single supplier for certain components, which adds risk because that supplier may at times be unable to meet our needs and because we may have limited negotiating leverage with sole-source suppliers. Identifying and qualifying dual and second-source suppliers can be difficult, time-consuming and may result in increased costs.”
