 Unaudited Quarterly Net Asset Value & Operational Update

NextEnergy Solar Fund, a specialist investor in solar energy and energy storage, announces it has today published its unaudited Q1 Net Asset Value ("NAV") and Operational Update for the three-month period ended 30 June 2026.

Quarterly NAV:

As of 30 June 2026, the Company's NAV was £420.8m (31 March 2026: £437.5m), representing a NAV per Ordinary Share of 73.2p (31 March 2026: 76.1p). The Company's Gross Asset Value ("GAV") was £902m (31 March 2026: £922m). Key drivers are set out below in more detail

NAV movements:

Time value: The time value reflects the change in the valuation as a result of changing the valuation date, prior to adjusting for any outflows of the Company. The increase in value is attributable to the unwinding of the discount applied to cash flows for the period when calculating the discounted cash flow.

Project actuals: Project actuals reflect the portfolio's actual performance versus budget, with the slight increase during the period being driven by higher than anticipated irradiance and generation, which was offset by lower than anticipated solar capture prices.

Solar power price forecasts: A net decrease in the UK power price forecasts provided by third-party forecasters, driven by a reduction in forecast commodity prices in the mid-term and a decrease in forecast demand in the longer term. 

BESS revenue forecasts: An increase in BESS revenue forecasts provided by a third-party consultant.

Inflation forecasts: A decrease in short-term inflation assumptions up to 2030. The Company continues to take a consistent approach to its inflation assumptions, using external third-party, independent inflation data from HM Treasury Forecasts and long-term implied rates from the Bank of England for its UK assets. For international assets, IMF forecasts are used. Long-term assumptions are aligned with market consensus.

Revaluation of NextEnergy III LP and co-investments: Movements in the fair value of the holding in NextEnergy III LP and the two co-investments.

Cash dividends paid: The dividends paid during the period, including both Ordinary Share and Preference Share dividend payments. This quarter's Ordinary Share dividend payment represents the final distribution under the Company's previous dividend policy.

Other residual value movements: Includes interest and fees paid on short term revolving credit facility, discount rate premium adjustment on cash flows on assets with useful economic life beyond 30 years, FX movements, incremental capex forecasts, planned outages, and other immaterial changes.

Gearing:

As of 30 June 2026, total gearing1, including Preference Shares, was 52.1% (31 March 2026: 51.2%). While this is above the Company's 50% debt to GAV target, the increase was driven by the reduction in NAV relative to existing debt, rather than any additional debt drawdown.

Exceeding the 50% target does not impact the terms or covenants of the Company's debt facilities, it simply restricts the Company from drawing further debt, which it does not intend to do. As set out in the Company's recently published strategic reset and roadmap, NESF is targeting further asset sales to reduce gearing to a range of 40% - 45%.

As previously announced, the Company is already in the advanced stages of its first asset disposal under the extended Capital Recycling Programme, with proceeds expected to be used to make further repayments of the revolving credit facility ("RCF").

The enterprise value gearing ratio applied to the Preference Shares held by USS was 63.3% (31 March 2026: 61.8%). As previously outlined, this does not impact the Company's current operations.

Operational update:

The Company has 99 operating solar and energy storage assets3 (31 March 2026: 99) with a total installed capacity of 839MW4 (31 March 2026: 838MW). The assets have a remaining weighted life of 22.0 years (31 March 2026: 22.3 years).

During the period, generation performance for NESF's UK and Italian assets was +4.9% versus budget (31 March 2026: -10.9%). The outperformance was driven by above-than-expected solar irradiance of

+10.3% (31 March 2026: -9.0%). The variance in performance was attributable to asset-level incidences

and limitations. 

The Company continues to run a proactive hedging strategy on its non-subsidised revenues to minimise risk and lock in future cash flows. The table below shows the hedged position using Power Purchase Agreements ("PPAs") of the 676MW UK NESF portfolio as of 30 June 2026.

The Company captured some near-term upsides from the wholesale market volatility in response to the conflict in the Middle East in the period and continues to lock in further power price hedges on a monthly basis as they become liquid.

Key assumptions:

Inflation Rate (UK RPI) Assumptions

Inflation Rate (UK CPI) Assumptions

Discount Rate Assumptions

Footnotes:

1. Total gearing is the aggregate of financial debt, and £200m of preference shares. The preference shares are equivalent to non-amortising debt with repayment in shares. Excludes total look-through debt of £23.3m since the Company does not have control over this debt for NAV based investments.

2. Excludes total look-through debt of £23.3m.

3. Excluding the $50m commitment into private vehicle NextEnergy III LP ("NEIII", formerly "NextPower III LP").

4. Including share in private equity vehicle NEIII and co-investments (Agenor and Santarém). Inclusion of NESF's 6.21% share of NEIII on a look-through equivalent basis increases total capacity by 49MW (31 March 2026: 48MW). Inclusion of NESF's 24.5% share of Agenor increases total capacity by 12MW (31 December 2025: 12MW). Inclusion of NESF's 13.6% share of Santarém on a look-through equivalent basis increases total capacity by 29MW (31 December 2025: 29MW).

5. Unlevered discount rate for Italian operating assets implying 1.50% country risk premium to 8.0%.

6. Unlevered discount rate for subsidy-free uncontracted operating assets implying 1.0% risk premium to 8.0%.

7. Risk premium on UK unlevered (8.00%) and UK levered assets (8.70% - 9.00%) for cash flows after 30 years.
