What SoundThinking, Inc. told the SEC could break it.
SoundThinking's risks split between who buys from it and how its hardware gets made. On the demand side, revenue is concentrated in a few large government contracts — the City of New York alone was 29% in 2025 — and the City of Chicago's 2024 non-renewal (once about 10%) shows how quickly losing one can sting. On the supply side, its proprietary ShotSpotter sensors are built by a single contract manufacturer with no long-term contract, and many standardized components come from concentrated regions, particularly Greater China, so US tariffs on Chinese-sourced parts raise its cost of revenues (tariff effects have already delayed its Brazil deployment).
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
- City of New York = 29% of revenue; revenue concentrated in few large government contractshigh
SoundThinking's largest customer, the City of New York, was 29% of 2025 revenue, and its revenue is concentrated in a small number of large government contracts; the City of Chicago's 2024 non-renewal (was ~10%) shows the volatility this creates.
“For the year ended December 31, 2025, our largest customer, the City of New York, accounted for 29% of our revenues.”
SEC filing →As of 2026
Geographic concentration
- sensor components concentrated in Greater Chinamedium
Many standardized components used broadly in SoundThinking's sensors are manufactured in significant quantities in concentrated geographic regions, particularly Greater China, exposing its supply chain to regional crises and trade measures.
“many of our standardized components used broadly in our sensors are manufactured in significant quantities in concentrated geographic regions, particularly 53 in Greater China.”
Regulatory & policy
- tariffs on China-sourced sensor components (raising cost of revenues)medium
Increased U.S. tariffs on components exported from China raise SoundThinking's cost of revenues (and tariff-related impacts already delayed its Brazil deployment), with further hardware/infrastructure tariffs threatening costs and supply.
“As a result, increased tariffs placed on components exported from China by the U.S. government will increase our costs of revenues.”
SEC filing →As of 2026
Supplier concentration
- single contract manufacturer for proprietary ShotSpotter sensors (no long-term contract)medium
SoundThinking's proprietary ShotSpotter sensors are produced by a single contract manufacturer with no long-term contract (purchase-order basis), and many key sensor components come from limited or sole sources with long lead times — a sharp single-source production risk.
“we use a single manufacturer, with which we have no long-term contract and from which we purchase on a purchase-order basis, to produce our proprietary ShotSpotter sensors.”
