Semtech (SMTC) concentration risks

The company's disclosed concentration profile has two interlocking moderate-share exposures — a geographic revenue skew toward China and a supply dependency on Chinese-sourced materials — plus two smaller customer dependencies. China, including Hong Kong, comprised 47% of net sales in fiscal year 2026, a moderate-share geographic exposure that is structural in character, reflecting where the company's end markets for wireless connectivity and IoT semiconductor products are concentrated. The exposure to a single country of that magnitude means trade policy developments, tariffs, export control changes, and local economic conditions in China have a disproportionate effect on revenue relative to the global footprint. The supply side reinforces the geographic dependency: certain products rely on rare earth elements for their manufacturing, with a significant majority sourced from China, a moderate-share dependency that is geopolitically linked to the same country risk as the revenue skew. This creates a situation where an adverse trade or regulatory development in China could simultaneously impair sales access and input material availability. Customer B and Customer A appear in the filing as the two individually disclosed customers, at shares that appear only in pipe-delimited table fragments and are therefore not cited as specific percentages here; both are smaller-share individual accounts. Because both individual customer names are anonymized and their revenue shares are qualitative in the source, the key concentration monitoring variables remain the China geographic exposure and the rare earth supply dependency rather than specific named customer relationships.
