Halma (LSE:HLMA) reports half-year results on 19 November, having already raised its Margin guidance in a confident September trading update. The safety, health and environmental technology group offers one of the smallest yields in the FTSE 100, yet one of its longest records of Dividend increases. That combination makes it an unusual case for investors who look beyond the headline income figure.

Tiny yield, formidable consistency

Halma's annual dividend is 24.74p per share, with the latest payment at 15.11p, as of 7 October 2026. The trailing 12-month Yield and the indicated yield are both 0.7%, which means a buyer today is receiving very little immediate income and is relying heavily on future growth.

The record is what sets Halma apart. The company has paid dividends for 47 consecutive years and has increased them for more than four decades in a row, one of the longest growth streaks on the London market. It has maintained that run through recessions, financial crises and the pandemic, which suggests a deeply embedded commitment rather than a recent policy choice.

The split between the two payments is also instructive. The final dividend, paid after the full-year results, is normally larger than the interim, which is why the latest figure of 15.11p sits well above half of the annual total. The interim announced alongside the half-year results is therefore a smaller instalment, and its growth rate is the number to compare with the prior year.

A yield of 0.7% should be read in context. Yield equals the annual dividend divided by the share price, so a company that grows its dividend every year but whose share price has also risen will still show a small percentage. For investors focused on the growth of income over time, the rate of dividend increase and the length of the record tell more of the story than the starting yield does.

Plenty of room to keep raising

The dividend rose 7.0% year on year, a steady rise that extends its long-established pattern of annual increases. The Payout Ratio of 25.1% implies Earnings cover of about four times. Halma retains around three-quarters of its earnings, and it reinvests heavily in acquisitions and organic growth.

For a retail investor, the appropriate comparison is therefore less a high-yield Utility and more a compounding Business that happens to pay a small and reliably rising dividend. The low yield is a function of how little of its profit the company chooses to distribute and of how the market prices its record of growth. A change in sentiment towards the shares would alter the yield without any change to the dividend, which is worth remembering when comparing Halma (LSE:HLMA) with higher-yielding stocks.

Cover of four times is also unusually wide for a company with such a long run of increases. It means earnings could fall sharply before the dividend came under pressure, and it explains why the board has been able to raise the payout through downturns. The more relevant constraint for Halma is not whether it can afford the dividend but how best to balance it against the Options for reinvesting.

September's upgrade and an active deal programme

Halma's most recent update, on 24 September, described solid progress in the first half with broad-based growth. It continued to expect low double-digit organic constant-currency Revenue growth for the year to March 2027, including a notable contribution from its photonics business. It raised its adjusted earnings before interest and tax margin guidance to between 23.5% and 24%, up from about 22.7%, and said order intake was ahead of revenue and of the prior-year period.

There was one modest offset: sterling's recent strength was expected to create a translation headwind of around £8m on revenue and about £2m on profit, if exchange rates hold.

Capital deployment has also been brisk. Halma had completed six acquisitions in the year to date, costing a record £515m, including Dreampath for about £238m and Pyxis for about £148m. It had also made three disposals raising about £83m net of costs, among them NovaBone for about £42m. This activity underlines how the low payout ratio is put to work, as cash not distributed to shareholders is recycled into acquisitions that have historically supported growth in earnings and, in turn, the dividend.

How the model supports the dividend

Halma operates as a group of specialist businesses, each serving niche markets where regulation, safety standards or health requirements create steady demand. Because many of its products are bought to meet legal or operational needs, revenue has tended to be less sensitive to the economic cycle than that of broader industrial groups. That resilience helps explain the unbroken run of dividend increases.

The Acquisition strategy adds a further layer. Buying small and mid-sized technology companies lets the group extend into new niches, while disposals prune activities that no longer fit. The balance between the two shapes returns on capital, and it is also why Leverage deserves attention when the pace of deal-making rises. A higher margin target, such as the 23.5% to 24% range now guided, gives additional room for the dividend to keep growing even if currency or deal costs absorb part of the gain.

What to watch

The 19 November results will reveal the first-half numbers behind September's upbeat language, and they should include the Interim Dividend declaration. Given the long record of increases, attention is likely to focus on the size of the increase rather than on whether there is one. Investors should also watch photonics demand, the margin achieved against the raised guidance, the effect of sterling and the extent to which the recent burst of deals affects the balance sheet.

The group's capacity to sustain growth at this pace will determine how comfortably the dividend can continue to rise from here. For followers of Halma (LSE:HLMA), the interim dividend and the commentary on order intake will be the two clearest signals of whether the momentum described in September has carried through.
