IMI (LSE:IMI) has lifted its full-year Earnings guidance, giving income investors fresh context for one of the better-covered dividends among UK engineers. The fluid and motion control group now expects Earnings Per Share of 137p to 143p, although its growth slowed to 2% in the third quarter, according to one report. For a share yielding just 1.1%, the argument rests on the dividend's rate of growth, not its starting level.

A small yield, healthy cover

Our figures, from a snapshot dated 7 October, show an annual Dividend of 34.2p per share and a latest interim payment of 12.1p. The trailing 12-month Yield is 1.1% and the indicated yield is also 1.1%. That is low by the standards of the FTSE 100, and income-focused investors would find substantially higher payouts elsewhere in the index.

The Payout Ratio of 25.8% is more striking. It implies cover of around 3.9 times, so only about a quarter of trailing earnings is being distributed. That leaves a large Margin of safety, and it means that the dividend could continue rising without the company straining its finances. It also leaves plenty of room for Investment and other uses of cash.

The raised guidance adds some useful perspective. An annual dividend of 34.2p set against an expected earnings range of 137p to 143p would be a similar ratio of roughly a quarter, although this compares the dividend in our snapshot with forecasts for the current year, so it is an illustration and not a forecast of the final payment.

A long record of payments

Growth of 10.0% year on year is well ahead of what many larger-yielding companies have managed, and it is the principal attraction for dividend investors here. At that pace, a low yield on the purchase price can build meaningfully over time, if the rate is maintained, which is by no means guaranteed.

The streak data adds depth. IMI has 46 years of continuous payments, among the longer records in our data, and five years of continuous growth. A payment record of that length, through multiple industrial downturns, is a real credential. However, the gap between the two figures shows that the dividend has not risen in every one of those years, with the current run of increases being much shorter than the record of payment itself. Continuous payment and continuous growth are different achievements, and only the first has been sustained for decades.

What the trading update showed

IMI's recent trading update covered the third quarter. Reports said the group raised its earnings guidance to the 137p to 143p range, with trading described as resilient in one report and solid in another. A separate report noted growth slowing to 2% in the quarter, and attributed the guidance change to earnings linked to Truflo.

The first half had been firmer. A report on the half-year results recorded rises in profit, Cash Flow and the dividend, while an earlier report mentioned a buyback outlined alongside results, which means that the ordinary dividend is not the only channel through which cash might come back to shareholders.

Slower quarterly growth alongside a guidance rise is a combination that deserves attention. Earnings can improve for a number of reasons, but the dividend's long-term progress ultimately depends on sustained Demand in the markets that IMI (LSE:IMI) serves.

What to watch

The full-year results will show whether earnings land in the 137p to 143p range and how large the final dividend is. Investors should watch whether the 2% pace of third-quarter growth proves temporary or marks a more lasting slowdown, and how order trends look across the group's end markets. It will also be worth checking whether the five-year growth streak extends, and how the board balances Buybacks with the dividend.
