London, June 23, 2026, 13:08 BST
Halma is trading 1.9% lower at 3,896 pence as of 13:07 BST in delayed London action. The stock is lagging the main market, with the FTSE 100 off 0.7% earlier. Diploma slipped 1.9%, Smiths Group is 1.3% lower.
Halma is still looking to recover after shares plunged 15.4% in one session on June 11. The drop came even with record annual results, as investors worried about slower organic growth heading into fiscal 2027. Halma flagged that photonics, its light-driven tech division for data-centre customers, would add less than before.
Halma’s regulatory feed didn’t show any new filings since June 16, when it had a director buying shares and a director declaration. Tuesday’s drop comes with no new operating developments, so it looks like more of the ongoing valuation reset.
Tech stocks in Europe slid 3.4% as traders reconsidered aggressive spending on AI and weighed the risk of rising rates. “This debt issuance is a trend that investors will need to keep watching out for the next one or two years,” said Kiran Ganesh, an executive at UBS. Reuters
Halma is looking for low-double-digit organic constant-currency revenue growth through March 2027, excluding acquisitions, disposals and currency shifts. The company sees photonics adding about five percentage points of “premium” growth, down from last year’s eight points. For fiscal 2026, revenue was up 15% to £2.582 billion. Adjusted EBIT grew 22% to £594.5 million, after stripping out acquisition and restructuring charges. “Growth was broad-based across all three sectors,” Chief Executive Marc Ronchetti said. Halma
Halma analysts still can’t agree. Matthew Donen at Morningstar said the guidance points to slower growth in photonics and the rest of the group. JPMorgan analysts warned the five-point photonics contribution won’t meet investor hopes. But Citi moved the other way, upgrading Halma to “buy” and raising its price target to £46 from £37 after shares sold off. Reuters
But the risk sits in one place. Around 20% of Halma’s group revenue comes from a single hyperscale technology customer. If that customer slows AI data-center spend, order conversion drops off, or interest rates go higher, Halma could struggle to hit its growth target and its valuation could take another hit.
Halma (LON:HLMA) is set for a July 9 ex-dividend date, with its annual meeting coming up on July 23. The company proposed a final dividend at 15.11p, putting the full-year total at 24.74p, which is up 7%. The final dividend is due for payment August 14.
