What Knowles Corporation told the SEC could break it.

Knowles uses a wide variety of raw materials — primarily metals and semi-processed/finished components — and is exposed to commodity-price fluctuations in precious and base metals including palladium, gold, brass, stainless steel and copper, which are used in its film/electrolytic/mica capacitors (Cornell Dubilier) and precision devices. Palladium in particular is a volatile, supply-constrained metal (significant Russian supply), so price spikes or supply disruption raise input costs for its Precision Devices segment. A specific metals-commodity input dependence.

Knowles discloses that the majority of its largest manufacturing facilities are located in China and Southeast Asia, so U.S./China/other trade-policy changes — tariffs, sanctions, export/import controls — present particular risks to its results. U.S.–China tariff escalation (and retaliatory tariffs from China and Mexico), plus China's stated policy of reducing dependence on foreign suppliers (decoupling/localization), threaten both Knowles' cost base and its access to the China market. With its manufacturing footprint concentrated in the most trade-policy-sensitive region, this is a thesis-central geopolitical/trade-policy exposure (combining geographic manufacturing concentration with active tariff/sanctions risk).

“Given that the majority of our largest manufacturing facilities are located in China and Southeast Asia, trade policy changes in the United States, China, or other countries, such as tariffs and sanctions would present particular risks for us”

Knowles relies on highly specialized suppliers and foundries for critical materials, components and subassemblies, and in some cases these are its sole source of supply — explicitly its ASIC and MEMS foundry partners. Some of these foundries are also strategic suppliers to one of Knowles' competitors or customers, adding allocation/priority risk. If a key or sole foundry became unable or unwilling to deliver, Knowles may not be able to identify or qualify an alternative supplier in time (semiconductor foundry requalification is slow), which could materially affect results. A genuine sole-source foundry dependence for its micro-acoustic/MEMS products.
