LSE:HLMA 20 November 2025 - 10 March 2026

Halma plc slipped 1.6% to close at 3,800 pence on Monday. Attention is turning to Thursday’s trading statement, where investors hope to see whether the British technology group can sustain its growth, a trend helped by data-centre investment. Halma’s valuation looks steep by UK standards right now. Shares have jumped roughly 42% in the past year, and they’re trading at about 41 times earnings. That’s despite the FTSE 100 slipping to a five-week low on Monday, pressured by rising oil prices and inflation concerns.

London, Feb 7, 2026, 09:14 GMT — Market closed Halma plc closed out Friday at 3,548 pence, gaining 0.74% for the session. That puts the FTSE 100 life-safety tech firm’s market cap near £13.4 billion. With shares changing hands at about 35 times expected earnings, the lofty P/E leaves the stock exposed to outsized swings if investors shift their rate outlook.
