About 3i Group plc

Full-Year Performance

The total return of £5.3 billion included a currency benefit of 77p per share. Net asset value per share rose to £30.30, up from £25.42 the year before.

The portfolio generated £1.9 billion of cash during the year, including proceeds of €1.1 billion, or £950 million, from the sale of TCR, which delivered a 3.6 times return on the original investment.

Action

Action remained the largest contributor, with a gross investment return of £4.5 billion, or 25% on opening value. 3i recognised £1.19 billion of proceeds and Dividend distributions from the Business during the year.

Action's net sales grew 16% in 2025, with like-for-like growth of 4.9%. It has continued to open new stores in Europe, adding to its footprint and bringing its low-price offer to more customers.

Portfolio Activity

Beyond Action, 3i continued to invest in and develop its portfolio, supporting management teams with capital and expertise. Portfolio realisations, such as the TCR sale, show how the group can crystallise value from mature holdings and recycle capital into new opportunities.

Shareholder Returns

The group launched a share buyback alongside its results. Returning capital through Buybacks is one way the board has sought to balance reinvestment and distributions.

Why the Discount Retail Model Matters

Action's formula combines a wide range of low-priced products, a rapid pace of new items and a simple store format. Because customers visit frequently and spend a modest amount each time, the retailer benefits from steady footfall.

Its purchasing scale allows it to keep prices low, and its Supply chain and store network have expanded across more than a dozen countries. This combination has made it one of the leading retailers in Europe.

Investment Approach

3i typically takes significant stakes in businesses with leading market positions, and works alongside management on strategy, acquisitions and operational improvements. Its experience across cycles helps it select opportunities with durable demand.

The group also manages infrastructure investments through a separate vehicle, adding Diversification to its portfolio. Active ownership means working with boards on strategy, capital allocation and succession, and 3i has a long record of helping businesses expand into new markets and categories. Careful selection of opportunities remains central to the approach.

Responsible Investment

3i integrates environmental, social and governance factors into its decision making and engages with portfolio companies on topics such as emissions, supply chain standards and employee welfare. These practices are part of how it seeks to build sustainable businesses.

Portfolio Companies

The wider portfolio spans sectors such as healthcare, industrial technology, consumer and business services. 3i typically supports its companies with bolt-on acquisitions, international expansion and operational improvements, working alongside management teams over several years.
