Informa stock advances as 2025 revenue and profit improve

Informa stock is supported by full-year 2025 numbers and a recent market valuation backdrop. The London-listed group reported £4.1 billion in revenue and £1.0 billion adjusted operating profit for 2025.

Informa stock (GB00BMJ6DW54) is anchored by 2025 results that showed £4.1 billion in revenue and £1.0 billion in adjusted operating profit, while the shares were recently valued on the London market at a level that keeps the group in investor view. The combination of a bigger revenue base and a four-digit profit figure gives the stock a clear financial reference point.

2025 revenue reaches £4.1 billion

For the full year 2025, Informa reported revenue of £4.1 billion and adjusted operating profit of £1.0 billion, according to the companys investor materials. That profit figure leaves the group with an adjusted operating margin of about 24%, a useful marker for a business built around exhibitions, business intelligence, and academic markets.

The comparison is the key point: those 2025 figures sit above the 2024 base and show the scale of the group after another year of growth. In investor terms, the margin profile matters because it ties revenue expansion to cash generation rather than headline size alone.

Margin stays near 24%

Informa also reported that its adjusted operating profit of £1.0 billion translated into an operating margin of about 24% in 2025. That level is important for a company whose earnings mix depends on recurring subscriptions, conference activity, and higher-margin digital information products.

The body of the latest report shows the same pattern in another way: revenue of £4.1 billion against adjusted operating profit of £1.0 billion means the group converted roughly one quarter of sales into operating profit. For a listed media-and-events business, that ratio is a central valuation input.

Product depth supports the model

Informa brands such as Omdia and its exhibition portfolio help diversify the group beyond one-off event cycles. Omdia sits inside the advanced information and intelligence part of the business, where subscription-style revenues typically provide more stability than pure event ticketing.

The strategic value of that mix is visible in the 2025 numbers: a £4.1 billion revenue base and £1.0 billion adjusted operating profit indicate that the company can scale while holding a healthy earnings conversion rate. That is one reason the stock remains tied to both growth and margin delivery.

Stock level and market value

Informa stock last traded on the London market at around GBP 8.00, with a market capitalization near GBP 10 billion as a recent reference point for the equity story. That valuation backdrop fits a company whose 2025 results confirmed both scale and profitability.

For the market, the main question is less about whether Informa is large enough and more about whether it can keep revenue around the £4.1 billion mark moving higher while protecting the roughly 24% operating margin. The stock therefore trades on execution rather than a single catalyst.

Omdia and events matter

Omdia is one of the clearer product references inside Informa because it links the group to recurring information services rather than only event attendance. That matters when investors assess whether the company can keep the profit mix resilient through the year.

The exhibitions side remains relevant as well, because the scale of Informa's revenue base gives management room to balance live events, digital products, and data services. In 2025, that mix supported £1.0 billion in adjusted operating profit.

Close around GBP 8.00

Informa stock was recently around GBP 8.00 on the London market, with the equity valued at about GBP 10 billion. Those figures frame the stock against the 2025 financial base rather than against a one-day move.

The central takeaway is numerical: £4.1 billion of revenue, £1.0 billion of adjusted operating profit, and roughly a 24% margin leave Informa positioned as a scaled, profitable UK-listed information and events group.
