The Group utilises a combination of in-house expertise and outsourced manufacturing and has trading operations in Europe, the Far East and the Americas. CML targets niche markets with strong growth profiles and high barriers to entry. It has secured a diverse, blue chip customer base, including some of the world’s leading communications equipment providers and industrial product manufacturers.

The spread of its customers and products significantly insulates the business from the cyclicality usually associated with the consumer side of the semiconductor industry. Growth in its end markets is being driven by factors such as the endless appetite for data to be transmitted faster and more securely in the commercial and industrial sectors, the upgrading of telecoms infrastructure around the world and the growing prevalence of private commercial communications networks for voice and/or data communications linked to the industrial internet of things (IIoT).

Semiconductor solutions are targeted predominantly at Wireless Communications applications demanding high reliability and durability.

The Group is cash-generative, with a strong, asset-backed balance sheet and a net cash position.
