Halma's Fiscal 2027 Growth Forecast and Market Reaction

June 11 (Reuters) - British health and safety device maker Halma forecast organic constant-currency revenue growth for fiscal 2027 at a slower rate than the previous year, sending its shares down nearly 15% on Thursday. 

Key Details of Halma's Outlook

Here are a few details:   

Revenue Growth Projections

• The company expects to deliver low double-digit percentage organic revenue growth in constant currency for the 12-month period through March 2027, compared with 16% organic growth in fiscal 2026.

Photonics Business Performance

• Halma's growth has been driven by its photonics business, which uses light-based technology in sensors and monitoring systems, including for data centres, due to demand fuelled by the rapid expansion of AI.

• The company's outlook includes growth of around five percentage points from the photonics business, which JP Morgan analysts said would likely disappoint investors.

Analyst Perspectives on Photonics

• Halma's outlook suggested a deceleration in revenue growth for both the photonics business and the rest of the group, Morningstar analyst Matthew Donen said.

Market Reaction

• Shares in FTSE 100-listed Halma were trading lower at 3,962 pence, as of 0825 GMT, making them the biggest laggards in the blue-chip index.

Financial Results
