Main revenue and product drivers for Diploma PLC

Within Life Sciences, Diploma supplies products and services to healthcare and environmental laboratories, where demand tends to be relatively stable and less cyclical than broader industrial markets, supporting recurring revenue streams.Kalkine Media as of 05/09/2026 In Controls and Seals, the company benefits from long?term customer relationships in mission?critical applications, where switching suppliers can be costly and time?consuming, contributing to customer stickiness.The Motley Fool UK as of 05/06/2026
