2025 Final Interim Dividend

The Board of International Public Partnerships Limited ('INPP', 'the Company'), the FTSE 250 listed infrastructure investment company, is pleased to declare the following distribution:

Increase in dividend frequency

As part of a package of portfolio optimisation measures, the Company previously announced an increase in the frequency of its dividend payments from six-monthly to quarterly, in order to provide investors with a more regular income stream. This is the fourth dividend to be declared under the new quarterly payment frequency. 

2025, 2026 and 2027 dividend targets

The Board continues to forecast a long-term projected annual dividend growth rate of c.2.5%. It notes that the 2025 annual dividend target of 8.58 pence per share has been achieved and confirms that the 2026 and 2027 annual dividend targets are 8.79 pence per share and 9.01 pence per share respectively. The target dividend growth rate is determined by taking into account the Company's ambitions to sustainably grow dividends over the long term whilst providing full dividend cash coverage.

Note: The above distribution guidance is provided by the Company in consultation with its Investment Adviser as a target only and is not a profit forecast. There can be no assurance that this target will be met or that the Company will make any distributions whatsoever. The times and dates in this announcement are expected times and dates only and are subject to change. The Board will continue to review whether scrip dividends are appropriate for future dividends.
