3i Infrastructure plc - Q1 performance update

Strong start to the new financial year. Portfolio performing well overall.  

3i Infrastructure plc ('3iN' or the 'Company') is an investment company whose purpose is to invest responsibly in infrastructure, delivering long-term sustainable returns to shareholders and having a positive influence on our portfolio companies and their stakeholders. This statement relates to the period from 1 April 2026 to 30 June 2026 (the 'Period').

Bernardo Sottomayor, Managing Partner and Head of European Infrastructure, 3i Investments plc, Investment Manager of the Company, commented:

"We have made a strong start to the new financial year. Our high-quality portfolio is performing well overall, with most companies trading in line with or ahead of expectations, and we have completed the sale of TCR, crystallising exceptional value and transforming the Company's liquidity. We are on track and excited to complete the new investment in the Lefdal Mine Datacenter campus this summer."

Highlights:

TCR sale completed: 3iN received proceeds of €1.1 billion on 17 June 2026, generating a c.3.5x money multiple and a c.19% gross annual IRR over the life of the investment. These proceeds were used to repay the Company's Revolving Credit Facility ('RCF') in full.

On track to complete new investment in the Lefdal Mine Datacenter campus ('LMD'): The Company expects to complete in the summer on the c.€300 million investment for a majority stake in LMD, a highly efficient data centre campus on the west coast of Norway. In the Period, the Company's investment manager, 3i, agreed to acquire a further 23 percent stake in LMD from the minority investor which is expected to be funded by third party coinvestors managed by 3i alongside 3iN. The agreed price of this transaction is in line with the terms agreed for the previously announced 3iN investment. The Company will benefit from improved governance terms with 3i managing 90 percent of the equity in the business, including control over the exit timing.

Refinancing activity: Tampnet successfully refinanced its debt facilities, positioning the company for its next phase of growth. This is a multi-currency, multi-tenor package placed across banks and institutional investors, totalling NOK 5.8 billion (c.£450 million). We continue to see strong demand to lend to our portfolio companies and are actively working to raise additional debt and/or refinance existing facilities across three more of our businesses.

Portfolio performing well: Our portfolio companies made a strong start to the new financial year, with most trading in line with or ahead of expectations. Infinis made good progress with 274MW of new solar capacity under construction in the Period and has added a further 230MW of consented solar capacity to its pipeline for future development. Tampnet has been awarded new connectivity contracts for two deepwater developments in the Gulf of Mexico and is making good progress expanding into new geographies. New CEOs have been onboarded at SRL and Ionisos.

Income in line with expectations: Total income and non-income cash was £52 million for the Period.

Final FY26 dividend payment and FY27 target: Payment of the final dividend for FY26 of 6.725 pence per share is due to be made on 10 July 2026. The Company is on track to deliver the FY27 dividend target of 14.30 pence per share, up 6.3% from FY26, which is expected to be covered by net income.

Balance sheet: Following receipt of the TCR proceeds, the Company cancelled the £300 million commitments under the accordion feature of the RCF. At 30 June 2026, the Company had a cash balance of £428 million and no drawings on the £900 million RCF. Subject to approval at the Company's AGM on 2 July 2026, this cash balance will be reduced by the payment of the final dividend of £62 million on 10 July 2026. The pro-forma cash position at 30 June 2026 after adjusting for completion of the LMD investment and payment of the final dividend is £107 million.
