What Sonos, Inc. told the SEC could break it.

Sonos sells primarily through third-party retail/channel partners rather than direct, and depends on them for the vast majority of its product sales. The largest, Best Buy, accounted for 14% of fiscal 2025 revenue (captured as an edge). Its contracts give channel partners significant discretion over placement and promotion, and they can favor competing consumer-electronics brands. Loss of, reduced shelf space at, or financial distress of a major channel partner — Best Buy in particular — would materially hurt revenue. A concentrated retail-distribution dependence.

“We are dependent on our channel partners for a vast majority of our product sales.”

Sonos concentrates its product manufacturing in a few Asian countries — China, Malaysia and Vietnam — so a catastrophic event (natural disaster, geopolitical disruption, labor or power interruption) near those facilities could significantly damage its ability to produce and ship product, with substantial recovery time. This physical single-region manufacturing concentration is distinct from the trade-policy (tariff) and supplier-count channels: even absent tariffs, a Southeast Asia disruption would halt supply. A concentrated manufacturing-geography exposure.

“Any catastrophic event that occurred near our headquarters, or near our manufacturing facilities in China, Malaysia or Vietnam, could impose significant damage to our ability to conduct our business”

Sonos imports substantially all of its hardware, so U.S. tariffs hit its cost base directly (tariffs and duty costs are an explicit component of cost of revenue; gross margin fell to 43.7% from 45.4%). After the 2018 China tariffs — from which it secured exemptions while it relocated production — it diversified its supply chain primarily to Vietnam and Malaysia, making China reliance for U.S.-bound product 'very modest.' But the U.S. has since proposed/imposed tariffs on countries beyond China, including Southeast Asia (exactly where it moved) and EMEA, and trading partners have threatened reciprocal tariffs. A concrete, already-incurred trade-policy cost exposure that its prior mitigation no longer fully insulates.

“Starting in 2018, the U.S. government imposed significant tariffs on China for U.S.-bound goods in our product categories. We received exemptions to almost all of those tariffs until such time as we were able to diversify our supply chain, primarily to Vietnam and Malaysia.”

Sonos depends on a limited number of suppliers for various key components used in its speakers — and from time to time on sole-source suppliers — and on a limited number of contract manufacturers to assemble its products. Many components have long lead times and are subject to industry-wide shortages and price swings. A shortage, price spike, quality issue, or failure at a sole-source component vendor or a key contract manufacturer could interrupt production; its efforts to diversify manufacturers may not succeed. Suppliers and contract manufacturers are unnamed, so this registers as a sole-source/limited-supplier risk.

“We are dependent on a limited number of suppliers for various key components used in our products, and we may from time to time have sole source suppliers.”
