What Cisco Systems, Inc. told the SEC could break it.

A reduction or interruption in Cisco's global component supply — driven by China-Taiwan relations, tariffs/trade tensions, natural disasters, component price spikes, or semiconductor-market consolidation — could limit supply or increase costs.

“A reduction or interruption in supply, including disruptions on our global supply chain, caused in part by public health emergencies, geopolitical tensions (including as a result of China-Taiwan relations, increasing tariffs or any other trade tensions) or a significant natural disaster”

Cisco receives certain components from sole suppliers and relies on a limited number of contract manufacturers and suppliers; inability of a CM or supplier to meet supply requirements could materially impact operating results.

“We receive certain of our components from sole suppliers. Additionally, we rely on a limited number of contract manufacturers and suppliers to provide manufacturing services for our products. The inability of a contract manufacturer or supplier to fulfill our supply requirements could materially impact future operating results.”

Cisco's corporate HQ and certain R&D operations are in the seismically active Silicon Valley, and some facilities are near rivers that have flooded; customers, suppliers and logistics centers in such regions have disrupted supply-chain flows in the past.

“Our corporate headquarters, including certain of our research and development operations are located in the Silicon Valley area of Northern California, a region known for seismic activity. Additionally, a certain number of our facilities are located near rivers that have experienced flooding in the past.”
