(Alliance News) - Diploma PLC on Thursday raised its guidance once again after a "very strong" third quarter, supported by its Controls business.
The London-based supplier of specialised technical products and services now expects organic revenue growth of 14% in the financial year ended September, raised from 12%.
In March, the FTSE 100 listing lifted its full-year organic revenue growth expectations to 9% from 6% previously. In May, it increased its forecast further to 12%.
Diploma also raised projections for full-year operating margin to around 26.5% from around 25% before. It had left margin guidance unchanged in May, after boosting it from 22.5% in March.
Diploma said this represents a further around 7% upgrade to consensus for adjusted operating profit of GBP454 million. In the financial year ended September 30, 2025, Diploma reported adjusted operating profit of GBP342.7 million.
Shares in Diploma rose 3.6% to 7,010.00 pence each in London, the biggest riser in the FTSE 100 index, which was down 0.5%. The stock has risen 44% in the past 12 months.
Diploma reported organic growth of 15% in the nine months ended June 30, driven by a "very strong" third quarter, building on the momentum seen in the first half of the financial year.
It highlighted "excellent" execution in "favourable" market conditions in Controls, with continued double-digit growth in IS Group, Clarendon, Peerless and Windy City Wire, while Seals performance was a little stronger than the first half. Performance in "challenging" Life Sciences markets was described as "resilient".
Diploma said acquisitions completed to date will add 6% to reported revenue growth and noted it has a strong acquisition pipeline and significant balance sheet capacity.
