Diploma PLC traded higher Tuesday, topping the FTSE 100. Investors kept buying into the distribution group’s growth story. Hargreaves Lansdown’s late price showed shares up 1.50% at 7,080p/7,085p. The FTSE 100 rose 0.57% at the same point. Diploma shares approached recent highs, valuing the group close to £9.5 billion. HL
No updated trading statement from Diploma in the past one to two days. Shares seem to be pushing higher on follow-through buying after a strong first half. In May, Diploma reported revenue of £851.1 million, a 17% rise. Organic revenue rose 15%, so the growth was from existing business, not acquisitions. Adjusted operating profit rose 33% to £208.9 million. Margin was up to 24.5%, a jump of 300 basis points. Investegate
Diploma is priced like a compounder, not a typical cyclical industrial. The company upped its FY26 guidance, now calling for 12% organic revenue growth, 6% from acquisitions, and around a 25% operating margin. CEO Johnny Thomson said, “The second half has started well and, despite the uncertain environment, we’re confident in our upgraded full year guidance.” Investegate
Diploma fans say its exposure to faster-growing sectors like aerospace, defence, data centres, energy, and life sciences should keep sales ahead of GDP. The company stayed active on M&A, reporting 15 deals in the last year for about £310 million. But the share price tells a different story. Diploma trades at a P/E near 39.7 times trailing earnings, according to HL, and its dividend yield is under 1%. That leaves little room for mistakes if growth slows, acquisition costs rise, or businesses like International Seals keep underperforming. Investegate
Diploma shares have run up and now mostly suit buyers comfortable with paying a high price for steady growth. Analyst consensus from the company as of June 9 sets adjusted FY26 EPS at 236.9p. At 7,080p a share, that’s a forward P/E close to 30. Adjusted EPS cuts out certain items to get at the main business. Investors look to the July 16 Q3 update. Strong organic growth might back up the valuation, but if growth slips the multiple will look tough to justify. Diploma PLC
