Diploma PLC (LSE:DPLM) has delivered a robust performance in the third quarter, prompting an upward revision of its full-year organic growth forecast from 8% to 10%. Reported growth for the year to date stands at 12%, with contributions from recent acquisitions helping offset currency headwinds.

In line with its growth strategy, Diploma invested around £39 million in two key acquisitions. The purchase of Haagensen A/S enhances its Seals offering in Denmark, while the acquisition of Alpha Laboratories marks its entry into the UK’s In Vitro Diagnostics sector—expanding its presence within the Life Sciences division. These moves are expected to reinforce the company’s competitive positioning and broaden its operational footprint.

Diploma’s outlook remains positive, supported by consistent financial performance and strategic execution. However, the company’s elevated price-to-earnings ratio and overbought technical indicators suggest investors may want to proceed with caution in the near term due to valuation concerns.
