Halma Raises Full Year Revenue Guidance on Photonics Strength

Halma plc (LON: HLMA) released a trading update today, signaling strong performance in the first half of its financial year.

Bolstered by unexpected growth in its Environmental & Analysis sector, the company has revised its full-year revenue growth expectations upward.

The company now anticipates low double-digit percentage organic constant currency revenue growth for the full year, a notable increase from the previously projected upper single-digit percentage growth. This revision is primarily attributed to robust growth within photonics, a segment within the Environmental & Analysis sector.

Order intake is said to remain a key indicator of Halma’s positive trajectory, with current figures exceeding both year-to-date revenue and the comparative period last year. The company’s adjusted EBIT margin is expected to remain modestly above the middle of its target range of 19-23% for the financial year, reaffirming profitability guidance.

While first-half cash conversion is expected to reflect investments in working capital and capital expenditures, the company anticipates full-year cash conversion to align with its key performance indicator (KPI) of 90%.

The company noted that the strengthening of the GBP is expected to negatively impact the group’s results through currency translation, a trend expected to persist in the second half of the year.

Halma’s half-year results for the period ending 30 September 2025 will be released on 20 November 2025.
