NextEnergy Solar Fund Limited

("NESF" or the "Company")

 2026 Sustainability and ESG Report

NextEnergy Solar Fund, a leading specialist investor in solar and energy storage, has today published its annual standalone Sustainability and ESG Report ("Report") for the year ended 31 March 2026, and announced its designation as a Natural Capital Fund by the Guernsey Financial Services Commission ("GFSC").

The Report is available to download from the Sustainability and ESG Reports section of the Company's website or via the following link:  [2026 Sustainability and ESG Report].

Background:

The purpose of the Report is to inform NESF stakeholders of the Company's approach to sustainability and Environmental, Social and Governance ("ESG") factors, how it executes its strategy, and how it creates impact. The Report is designed to be read in conjunction with the NESF Annual Report for the year ended 31 March 2026.

The intent of the integrated disclosures in the Report is to provide consistent, decision-useful information on sustainability and ESG issues to investors and other users of the Company's Annual Report. As such the Report makes disclosures in alignment with the General ("S1") and Climate ("S2") standards of the International Sustainability Standards Board ("ISSB") IFRS, as well as the recommendations of the Taskforce on Nature-related Financial Disclosures ("TNFD").

Key ESG highlights:

·    Climate:

o  Generated 844GWh of clean electricity, enough to power c.256,714 homes for a year.

o  Avoided c.275,583 tonnes of carbon emissions, reducing reliance on fossil fuels.

o  c.96% of the portfolio is not exposed to material physical climate risks, demonstrating strong asset resilience.

o  Released its first Climate Transition Plan which sets out the Company's ambition to progressively decarbonise NESF's portfolio across both its operations and value chain.

·    Nature:

o  68% of land under management is now restored or rehabilitated, supporting improved biodiversity.

o  89% of land is actively managed for both energy generation and nature ("dual use"), well ahead of long‑term targets.

o  100% of sensitive sites are covered by dedicated Nature Management Plans, protecting ecosystems where it matters most.

·    People:

o  Board gender diversity 60:40 (female/male).

o  c.£167,000 community and charitable funding.

·    Reporting:

o  Maintained EU Article 9 classification, reflecting a core objective of sustainable investment, and continued reporting alignment with the ISSB and TNFD.

·    Recognition:

o  Achieved Natural Capital Fund designation from the GFSC, a regulated recognition of measurable positive environmental impact.

Approach to sustainability and ESG reporting:

There are three key priority areas in the NESF Sustainability and ESG Framework: People, Nature and Prosperity. Each priority area is underpinned by three focus topics as set out in the NESF Sustainability and ESG framework. These priority areas and topics are the result of a double materiality assessment undertaken in 2023. These areas remain a priority for the Company. The Framework structures NESF's approach to creating positive sustainability and ESG outcomes alongside generating long-term total returns.

The Company's reporting strategy aligns with the Framework's priority areas and those of the ISSB and TNFD, ensuring stakeholders receive decision-useful insights into its performance. The information NESF discloses includes climate and nature-related considerations across its construction activities, direct operations, and value chain. NESF also reports on key people topics, such as health and safety, diversity, equity and inclusion, community engagement, and human rights.

Natural Capital Fund designation:

In February 2026, the GFSC recognised the Company's long‑standing commitment to delivering measurable benefits for nature while generating investor value and awarded the Company one of its first Natural Capital Fund designations.

This designation puts the Company at the forefront of nature‑positive renewable investment and reporting and represents an important milestone for the renewable infrastructure sector, recognising the role that well-managed solar assets can play in delivering measurable natural capital outcomes.

Josephine Bush, Chair of the NESF Board's ESG Committee, said:

"NESF continues to play an important role in the energy transition, providing resilient, domestically generated renewable power in an increasingly uncertain world. During the year, the Company made meaningful progress in delivering its sustainability strategy, including publishing its first Climate Transition Plan and achieving Natural Capital Fund designation, recognising its positive contribution to the environment. With a strong framework in place, NESF is well positioned to manage climate and nature-related risks while capturing the opportunities arising from the energy transition and delivering long-term value for shareholders."
