Steadier than most

Based on beta - how much the price swings versus the whole market. Bumpier isn't bad; it just means a rougher ride, which matters more the sooner you might need the money.

Why has it been moving?▼ -2% past week · ▲ +11% past year

Prices move on results, news and the mood of the whole market - no single headline explains a day, and a quiet week is usually just noise, not a signal.

The bull case

Long-term demand for data centres and green energy drives asset values up.

The bear case

A prolonged period of high interest rates making debt refinancing difficult.

What does 3i Infrastructure plc do?

Think of 3i Infrastructure as a professional collector of 'boring but essential' assets that keep the country running. Owning these utilities and digital networks brings in reliable income through long-term contracts. How they handle their debt and interest rates is worth following, as these big infrastructure projects are often expensive to build and maintain.

Does 3i Infrastructure plc pay a dividend?

Yes - 3i Infrastructure plc currently pays a dividend of about 3.5% a year (the yearly payout as a share of the price). A dividend is a slice of profit handed to shareholders; the yield moves as the price moves, and a company can cut or stop it.

What do the numbers say about 3i Infrastructure plc's dividend?

There's no rating here, and we don't judge whether the dividend will continue - that would be advice. Here are the figures income investors usually look at, and what each one means, so you can weigh it up yourself.

Dividend yield3.5%The yearly dividend as a percentage of today's price. A very high figure often means the price has fallen because the market expects a cut, so a big yield is a question to look into, not a prize.
Payout ratio41%The share of profit paid out as dividends. A lower figure leaves headroom; near or above 100% means most or all of the profit is going out as dividends.
Dividend cover2.5×Profit divided by the dividend (the payout ratio the other way up). As a rough convention many income investors like around 2× or more; below 1× means the company paid out more than it earned that year.

Figures are from the latest available data and can be distorted by one-off results. Past payments don't predict future ones, and a dividend can be cut at any time. This lays out the numbers to help you understand them - it is not a view on what will happen.
