Q3 Performance and FY25 Guidance Upgrades

In its trading update for the nine months ended 30 June 2025, Diploma reported organic growth of 10%, up from the previously guided 8%, citing strength in the third quarter. Reported growth year-to-date stood at 12%, with 4% attributed to acquisitions and a minor offset from FX headwinds.

Operating margins continue to impress and remain in line with the upgraded FY25 guidance of approximately 22%. This follows 21.5% adjusted margin recorded for the first half of FY25, driven by operational leverage and effective cost controls.

First Half Performance Reinforces Outlook

For the half-year ended 31 March 2025, Diploma posted:

  • 14% reported revenue growth, with 7% from acquisitions

  • 23% increase in adjusted earnings per share

  • 19.1% return on capital, up 110 basis points

  • Cash conversion and balance sheet health, supporting future investments

Acquisitions and Market Diversification Support Long-Term Growth

Diploma invested approximately £39 million in two key acquisitions during the quarter:

  • Haagensen A/S (Seals) – enhances M-Seals’ operations in Denmark

  • Alpha Laboratories (Life Sciences) – marks Diploma’s entry into the UK In Vitro Diagnostics market

These deals not only strengthen Diploma’s geographic and product footprint but also demonstrate its focus on high-margin.

Diversified Model Insulates Against Volatility

Diploma’s diversified operating model and focus on local supply chains continue to offer resilience in a volatile macroeconomic environment. The company notes a limited impact from tariffs, highlighting its ability to manage geopolitical uncertainties while driving organic and inorganic growth.

Diploma’s blend of consistent organic growth, prudent acquisitions, rising margins, and high capital efficiency paints a compelling investment story. Analysts from Stifel Europe and Berenberg reaffirm their BUY ratings, with up to 11.54% upside potential, backed by the company’s upgraded FY25 outlook.
