CML Microsystems is a British company that designs microchips used in wireless communications and data storage products. Its chips go into devices like professional radios, industrial equipment, and embedded storage systems. The company sells to electronics manufacturers and system builders, mainly in defense, industrial, and telecommunications markets.

CML makes money by selling its semiconductor chips and licensing its chip designs to other manufacturers. It operates primarily in the United Kingdom but sells to customers across Europe, North America, and Asia. The company is small, with a market cap near zero on public exchanges, and competes by focusing on niche, specialized chip applications rather than high-volume consumer markets. Its negative operating margin shows it is currently spending more than it earns, which is a real financial risk. The key challenge ahead is returning to profitability as demand in its core industrial and communications markets recovers from a prolonged inventory correction that has weighed on semiconductor sales broadly.
