PANTHEON INFRASTRUCTURE PLC

Publication of Sustainability Report

Pantheon Infrastructure PLC ("PINT" or "the Company"), the listed global infrastructure fund, has published its Sustainability Report for 2025 (the "Report").

The Report is available to read and download from the Sustainability page on PINT's website: Sustainability - PINT (pantheoninfrastructure.com). The Report contains the Company's product-level disclosures aligned to the recommendations of the Task Force on Climate-related Financial Disclosures ("TCFD") and the Financial Conduct Authority ("FCA") ESG Sourcebook, including portfolio-level Scope 1, 2 and 3 greenhouse gas ("GHG") emissions. The Report also includes the Company's Part B UK Sustainability Disclosure Requirements ("SDR") Disclosure.

PINT's annual EU Sustainable Finance Disclosure Regulation ("SFDR") Periodic Report and the Company's UK SDR consumer-facing disclosure are also available on the Company's website.

As an Article 8 fund under SFDR, sustainability is central to the Company's approach to investing and key to building a resilient infrastructure portfolio. PINT believes that a focus on sustainability is a driver for value protection and value creation, alongside the traditional emphasis on risk mitigation.

For the second consecutive year, the Company has reported against the Private Markets Decarbonization Roadmap ("PMDR") framework, with approximately 84% of the portfolio by NAV invested in either Climate Solutions or Decarbonisation Leaders[1], up from 65% in 2024. Climate Solutions are companies that directly or indirectly enable others to decarbonise through low-carbon technologies and services, while Decarbonisation Leaders are those that have made progress reducing their own emissions or have a robust decarbonisation plan in place. During the year, 35% of the Portfolio advanced under the PMDR framework, demonstrating progress in their decarbonisation actions.

Andrea Finegan, the Chair of PINT's Sustainability Committee, commented:

"The current macroeconomic and geopolitical environment represents both a challenge and an imperative for responsible infrastructure investors. The Sustainability Committee supports PINT in navigating these developments, providing oversight and informing strategic decisions. We remain committed to staying at the forefront of sustainability best practice, enabling PINT to continue delivering long-term value for shareholders."

Richard Sem, Partner at Pantheon, PINT's investment manager, commented:

"Infrastructure managers continue to demonstrate strong sustainability maturity, particularly with respect to climate-related matters. Our Infrastructure Climate Engagement Programme now monitors performance across more than 1,000 infrastructure assets, reflecting Pantheon's commitment to integrating material sustainability factors throughout the investment lifecycle, with a continued focus on decarbonisation as a driver of resilience and value for PINT's shareholders."
