US SOLAR FUND PLC (USF, the "Company")

Dividend Declaration and Interim Results to 30 June 2021

US Solar Fund PLC (LSE: USF) is pleased to announce its interim results for the period ended 30 June 2021 and declare an interim dividend of 1.25 cents per ordinary share for the three month period to 30 June 2021 ("Second 2021 Interim Dividend").

Highlights to 30 June 2021

• One transaction closed during the period bringing the total portfolio to 493MWDC of operating capacity across 42 projects in four states, with a variety of investment grade offtakers S&P rated A to BBB. Portfolio revenues are 100% contracted at fixed or escalating prices for a weighted average of 14.9 years.

• The operating portfolio performed well in the first half, with generation within 0.9% of budget. Above-budget performance in Oregon and Utah was offset by underperformance due to contractual curtailment in California and utility outages and maintenance in North Carolina.

• Period end unaudited Net Asset Value (NAV) of $313.3 million or $0.943 per ordinary share, a 2.8% decrease from the 31 December 2020 NAV per ordinary share of $0.970.

• The NAV per share decrease was primarily due to a lower US merchant electricity price forecasts, reflecting COVID uncertainty at the time these forecasts were released during 2020 and early 2021. Since the period end, US merchant price forecasts have trended upwards again due to a reduction in COVID-related sentiment and an increasingly bullish outlook for carbon pricing to 2050. USF's cashflows during the contracted period (weighted average PPA term remaining of 14.9 years) are not impacted by changes in merchant electricity price forecasts.

• The impact of merchant electricity price forecasts was partially offset by favourable reductions in discount rates resulting from the portfolio's continued transition from construction phase to full run-rate operations and the reduction in leverage achieved through the refinancing of the Heelstone portfolio.

• The Company initiated a 12-month Placing Programme with an Initial Issue targeting $105 million. The Initial Issue closed on 7 May significantly oversubscribed, raising gross proceeds of $132 million from existing and new investors. Approximately $92m of these proceeds have been used to pay down or refinance existing debt facilities associated with the Heelstone portfolio with the remainder available for acquisitions (including Tranche Two of Mount Signal 2 (MS2).

• Total dividend of 2.5 cents per ordinary share declared during the period. The Company remains on track to deliver its 2021 annual dividend target of 5.5 cents per ordinary share which is expected to be covered from operating cashflows.

• At 30 June 2021, the Investment Manager's pipeline included 2.2GWDC of high-quality assets (including Tranche Two of MS2), with an aggregate value of approximately $2.2 billion and a weighted-average PPA term of 15.2 years.

Key Metrics

Second 2021 Interim Dividend

The Company is pleased to declare a Second 2021 Interim Dividend of 1.25 cents per Ordinary Share, as timetabled below:

Any such dividend payment to Shareholders may take the form of either dividend income or "qualifying

interest income" which may be designated as an interest distribution for UK tax purposes and therefore

subject to the interest streaming regime applicable to investment trusts. Of this dividend declared of 1.25

cents per Ordinary Share, 0.95 cents is declared as dividend income with 0.30 cents treated as qualifying

interest income.

This quarterly dividend is in line with the Company's target full year dividend of 5.5 cents per share. The

Company expects to declare modestly lower quarterly dividends for the first and second quarters and slightly higher quarterly dividends for the third and fourth quarters due to the cash flow profile of the assets.

Highlights after Period-End

• In August, the Investment Manager announced that John Martin would be stepping down as CEO to take up a position as CEO of Windlab Pty Ltd. Liam Thomas, previously CIO, was appointed as NESM's new CEO.

• In September, the Company also increased the size of the undrawn $25 million RCF to a $40 million facility, which remains undrawn, and extended the tenor for two years.

Gill Nott, Chair of US Solar Fund, commented:

"The last six months represent the first full period that our solar power assets were fully operational, a significant milestone in our development. To that end, we're pleased to declare our second quarterly dividend, as part of our committed target of 5.5 cents per ordinary share per year.

Despite the headwinds of the pandemic, which are looking more favorable as we enter our second half, we continue to make strong progress towards future growth. We made our sixth acquisition and completed an oversubscribed capital raise during the period, and would like to thank our existing and new investors for their ongoing support."

Liam Thomas, CEO of New Energy Solar Manager, added:

"The US solar market continues to offer attractive opportunities. President Biden has clearly made the climate change and decarbonisation one of his administration's core priorities, with a series of executive orders, pressure on federal agencies to speed up their clean energy transition, and most recently his bipartisan Infrastructure Investment and Jobs Act, which allocates over $60 billion to power infrastructure.

The White House has backed this up with plans to further extend and expand of the successful investment and production tax credits. We expect these will benefit the solar rollout, supporting the administration's goal for solar to increase tenfold to 30% of US power production by the end of this decade.

Our focus remains on delivering maximum value from the current portfolio of projects and continuing to grow the fund with new investments in solar and energy storage."

2. Chair's Statement

I am pleased to present the 2021 Interim Report for US Solar Fund plc for the period ended 30 June 2021. The period was marked by a number of significant achievements for the Company. In addition, the new Biden Administration has given a strong indication of further support for the renewables sector and solar development. The Board believes that the US solar market continues to show very considerable scope for expansion and that USF remains well positioned to invest into this growth. The Board and the Investment Manager have continued to operate successfully and efficiently across three continents, with virtual meetings held regularly on both a formal and informal basis, including holding the AGM online.

This last six-months marked the first period that the Company's entire portfolio of solar power assets was fully operational. As a result, the Company paid its first quarterly dividend in line with the Company's target full year dividend of 5.5 cents per Ordinary Share. Year to date, generation is 0.9% below budget, predominantly due to unscheduled maintenance, intermittent grid outages and the Mount Signal 2 (MS2) project in California experiencing almost a full year's curtailment allowances for both the prior and current year periods during the first six months of 2021. Dividend cash cover remains strong at 4.61x for the six months ended 30 June 2021.

In March, USF completed its sixth acquisition, 25% of MS2, bringing the portfolio to 42 fully operating projects in four states totaling 493 MWDC. In May, the Company completed a capital raising exercise with $132 million in gross proceeds, significantly exceeding its $105 million target. On behalf of the Board, I would like to thank existing shareholders for their support and welcome many first-time holders to the register.

Throughout the period, USF shares have traded between $1.00 to $1.09 on the London Stock Exchange. At 30 June 2021, the Company's shares were trading at $1.015 per Ordinary Share. This represents a 7.6% premium to the NAV of $313.3 million or $0.943 per Ordinary Share. Including dividends paid and reinvested during the period, shareholder total return from inception to 30 June is 4.93%.

CAPITAL RAISING AND REFINANCING

We were delighted by the market response to the capital raising in May of $132 million with strong support from existing and new investors.

The main purpose of the capital raising was to refinance the existing debt facilities associated with 177 MWDC portfolio of 22 projects acquired in 2020 (Heelstone Portfolio). Shortly after completing the raise, the existing debt facility was repaid with the proceeds of a new debt facility from a new lender and approximately $92 million of equity from the capital raise (Heelstone Refinancing). The refinance reduces the effective interest rate for the Heelstone Portfolio from approximately 6.25% to less than 3% per annum and brings fund gearing to approximately 40%, in-line with the long-term target of 50%. The Company is evaluating its strong pipeline of assets for suitable investments, including storage opportunities at existing sites, and the option over a further 25% of MS2, to deploy the additional proceeds raised.

PERFORMANCE

USF's unaudited NAV at 30 June 2021 was $313.3 million or $0.943 per Ordinary Share, a 2.8% decrease from the 31 December 2020 NAV of $0.970 per Ordinary Share and a 2.2% decrease to June 2020 NAV of $0.964 per share. The downward movement was primarily due to a decrease in merchant electricity price forecasts during the period, partially offset by reductions in discount rates.

USF's cash flows during the PPA term are fully contracted and not impacted by changes in merchant electricity price forecasts. However, these forecasts are used to estimate revenue received in the post-PPA period, so they still have an impact on NAV. Pleasingly, since 30 June 2021, we have seen an improvement in merchant pricing forecasts reflecting a reduction in COVID-19 uncertainty and increasingly bullish carbon price assumptions relating to net zero targets. We expect this outlook to be reflected in the next valuation.

The impact of merchant electricity price forecasts was partially offset by favourable reductions to discount rates as the portfolio has transitioned from construction phase to full run-rate operations and by a reduction in leverage resulting from the refinancing of the Heelstone Portfolio.

Reductions in discount rates typically occur as a project progresses from construction start to one full year of operations due to lower risks associated with the project. As of June 30, 2021, the portfolio has reached run-rate operations with the exception of our largest asset, Milford. We expect to recognise an incremental reduction in discount rate as the asset reaches a full year of operations during H2 2021.

PORTFOLIO

In March, the Company acquired a 25% interest in the 200 MWDC MS2 project in California, with an option to acquire a further 25% interest prior to March 2022. This sixth acquisition brings the Company's operating portfolio to 42 solar power projects totaling 493 MWDC. All projects have investment grade PPAs for 100% of electricity generated, and the weighted average remaining PPA of portfolio is 14.9 years. The long-term contracted cash flows of USF's portfolio partially mitigate the impact of power price fluctuations on NAV as the merchant power price forecasts only impact revenue after the PPA terms.

DIVIDEND

The Company declared a dividend of 1.25 cents per Ordinary Share in September 2021 for the quarter ending 30 June 2021, totaling 2.5 cents per Ordinary Share for the six-month period. The Company confirms its target 5.5 cent annual dividend, fully covered by operating cash flows.

It is worth noting that USF's highest power generation, and therefore operating cash flows, are produced in the summer months. Allowing for the time taken for electricity sales to be converted to distributable cash flow at the Company level, the profile of dividend payments throughout the year reflects this seasonality of the Company's underlying cash flows.

OUTLOOK

The US utility-scale solar market continues to experience strong growth. During the first quarter of 2021, the US utility scale solar market installed 3.6GWDC of capacity, representing the largest first quarter of installations to date. This momentum is expected to continue throughout the year with 17.9GWDC of solar expected to be installed over the course of 2021, a 25% increase on the total capacity installed in 2020 (14.3GWDC). Installations have been driven by the increase in decarbonisation targets from a variety of offtakers, a renewed focus on clean energy deployment at the federal level, and the continued expansion of state-level renewable energy targets. This is reflected by a strong opportunity pipeline offering numerous high-quality construction-ready and operational solar opportunities, as well as the potential to install energy storage at existing sites

In late March, the Biden Administration announced the American Jobs Plan, which is focused on creating jobs and upgrading US infrastructure. Approximately $60 billion has been allocated to energy infrastructure with a focus on increasing renewable power connection to the grid. A second and related package includes an extension and expanded direct-pay (cash payment for up to 85% of the tax credit) investment tax credit (ITC) and production tax credit for clean energy generation and storage. These have not yet passed through Congress, however, should any of the proposed policies be endorsed, there would be a significant positive impact on the US utility scale solar market.

In April, the parent of the Investment Manager became a signatory to the United Nations sponsored Principles for Responsible Investing

(UN PRI). We are also reviewing European sustainability and Environmental, Social, and Governance (ESG) disclosure frameworks to see how they might best be applied to USF. USF complied with pre-contractual disclosure requirements as part of our recent equity raising to meet the European ESG disclosure obligations for EU domiciled investors and prospective investors. Given the volume of capital from the EU flowing into sustainable funds and the advance of reporting frameworks there, we believe USF would be well-served to be aligned with EU reporting frameworks and are working to implement this.

While many countries globally have moved between reopening and shutting down and vaccination levels in the US and UK increase, the pandemic continues to impact many sectors. However, as we have previously commented, the solar industry in the US has largely been considered critical infrastructure, so COVID-19 continues to have no material impact on USF's on-the-ground operations. Service staff continue to travel to

sites to conduct work as needed and the Company continues to operate efficiently and smoothly, despite international travel restrictions. The pandemic has impacted supply chains for many industries, including solar. Supply chain impacts for USF are limited as the current portfolio is fully operational, and spare parts inventories are maintained for sites based on our independent engineers' recommendations at the time of acquisition.

Finally, during the reporting period, the Investment Manager announced that CEO John Martin is stepping down and that Liam Thomas, who is currently CIO, is replacing him. We thank John for his contribution to USF's establishment and initial growth, and we are pleased that Liam is taking over the role given his knowledge of the US market, the portfolio, and his relationships with many shareholders.

3. Investment Manager's Report

SUMMARY OF THE PERIOD

During the reporting period, the Investment Manager closed its sixth acquisition, a 25% stake in the 200 MWDC Mount Signal 2 project in California, bringing the portfolio to 42 assets across four US states totaling 493MWDC. The portfolio performed close to expectations with generation 0.9% below budget. This was largely driven by curtailment at MS2, where two years of contractual curtailment took place in the first six months of 2021. Budgeted production assumes curtailment is spread evenly over each PPA contract year (periods commence 1 June), so there is expected to be minimal impact for the remainder of 2021.

All cash flows from USF's assets are contracted in the US with investment-grade offtakers for a weighted average of 14.9 years. This was the first six-month period when all assets were fully operating, and USF commenced paying the full target dividend. USF's Q1 2021 dividend was

1.25 cents and Q2 2021, which is announced with this report, is 1.25 cents, totaling 2.5 cents for the period. The payments are in line with the Company's annual target dividend of 5.5 cents per Ordinary Share.

On 13 April, USF announced it was initiating a 12-month Placing Programme with an Initial Issue targeting $105 million. The Initial Issue closed on 7 May significantly oversubscribed, raising gross proceeds of $132 million from existing and new investors. Shortly after the completion of the capital raise, USF used $92 million of equity to successfully refinance, the existing debt facilities associated with a 177 MWDC portfolio of 22 projects acquired in 2020 (the Heelstone Portfolio). This refinancing benefits USF by lowering overall gearing to approximately 40% (below the long-term target of 50%), reducing sensitivity to changes in key assumptions including long-term power prices, and enhancing dividend coverage.

COVID-19 had no material impact on USF during the reporting period.

INVESTMENT PORTFOLIO

In March 2021, USF announced the financial close of a 25% interest (Tranche One) in MS2, a 200MWDC operating solar plant located in the Imperial Valley of Southern California, USF has an option to acquire a further 25% interest (Tranche Two) for $22 million subject to a

performance-based adjustment mechanism which can adjust the price upwards or downwards by up to $1 million. USF may exercise the Tranche Two option for up to 12 months from Tranche One completion (by March 2022), with Tranche Two completion subject to the same customary third-party consents as Tranche One.

This acquisition increases USF's total portfolio to 493MWDC of fully operational assets diversified across four states. USF's portfolio is fully operational with all production sold to a variety of investment-grade offtakers (S&P rated: BBB to A). The Investment Manager continues to work diligently to assess prospective investment opportunities to add to the portfolio.

US SOLAR FUND STRUCTURE

The following diagram is provided to assist with understanding the financial statements set out in this Interim Report.

USF invests in its US-based subsidiary, USF Holding Corp., via a combination of debt and equity. USF is entitled to a Management Services Agreement (MSA) fee for the provision of management services to USF Holding Corp. USF Holding Corp. reimburses USF for investment costs, and costs associated with providing capital and advice to acquire underlying US Solar Assets. In addition, the Company earns interest on an intercompany loan to USF Holding Corp. Cash may also flow from USF Holding Corp. to USF as a dividend or return of capital, which is distributed to USF Holding Corp. on a periodic basis from the Company's underlying Solar Assets.

There are no restrictions on the movement of cash between USF and its subsidiary. As of 30 June 2021, the Company and USF Holding Corp. have available cash of $16.1 million and $10.4 million respectively, for a total balance of $26.5 million which may be used to meet the obligations of USF. At 30 June 2021 an undrawn $25 million revolving credit facility (RCF) was in place at USF Avon LLC (a wholly owned subsidiary of USF Holding Corp.), providing further liquidity support. After the end of the reporting period USF increased the size and tenor of the RCF to $40 million and two years.

OPERATING ASSET UPDATE

Table 2: H1 2021 Operating Portfolio Performance by State

Construction for all USF projects was completed by the end of 2020, and the period ending 30 June 2021 was the first six-month period during which the portfolio was fully operating. Also during the period, USF completed the acquisition of 25% of MS2, adding 50MWDC of capacity

to the portfolio from the start of the second quarter. The portfolio performed well during the reporting period, with actual production of

449GWh (including reimbursed curtailment) which was 0.9% below the budgeted or forecast production of 453GWh. USF measures "Actual" performance against "Budgeted" performance. "Actual" production is the number of GWh generated and sold to the offtaker. "Budget" (also called "Forecasted") is the P50 production forecast for the plant before any adjustment for experienced weather conditions. Budget production

is based on a production model and assumptions verified by an independent engineer at the time of acquisition, taking into account the location of the site, design of the plant and equipment used, degradation of equipment over time, planned maintenance outages, and unplanned maintenance and grid outages.

NORTH CAROLINA

In North Carolina, performance was 7.6% below budget, primarily due to unscheduled maintenance and intermittent grid outages. A utility outage at the 6.7 MWDC Tiburon project was experienced in Q2 2021 which has since come back online. The 6.2MWDC Nitro site also remained offline for several months over the period, as a result of an equipment failure, with site remediation completed in Q2 2021. There was also minor unscheduled maintenance at several other sites due to offline site inverters and combiner boxes over the reporting period, which have since been rectified.

OREGON

The Oregon portfolio, comprising 28% of portfolio capacity, performed 4.5% above budget for the reporting period due to higher than budgeted plane of array irradiance experienced, but did experience some utility outages, cable repairs and substation conductor issues. All outages

that were experienced over the quarter have been investigated and restored. The cable repairs commenced in March and are expected to be completed in Q3 2021. This work is covered by insurance and the project receives business interruption proceeds until repairs are complete.

UTAH

In Utah, the Company's largest single asset, Milford, which comprises 26% of USF's portfolio capacity by MWDC, continues to show strong performance at 3.6% above budget. Milford has been performing well over the period due to the asset's stronger than budgeted availability factor. As Milford commenced commercial operations in Q4 2020, 30 June 2021 marks Milford's first full half-year of operations.

CALIFORNIA

Performance in California was 7.8% below budget for the period, largely driven by curtailment10 at MS2. Under MS2's PPA, the offtaker has the right to curtail MS2 for economic reasons throughout the contract year up to a cap, after which any further curtailment is compensated.

The Investment Manager's budget and NAV assumes that the full annual curtailment cap is spread evenly across all 12 months, however, the offtaker exercised almost its entire contractual curtailment allowance for both the prior and current contractual years during the first six months of 2021, which had an outsized impact on performance over the period. Therefore, no further material economic impact is expected during

this contract year (ending 31 May 2022), and commensurate outperformance against budget during the next half-year is expected (subject to normal operations).

The two smaller assets in California performed above budget over the reporting period.

FUNDS COMMITTED

Since inception, USF has invested $283 million into the operating portfolio. USF has $38 million of investable cash remaining, which is intended to be used to acquire Tranche Two of MS2 or other accretive investment opportunities should they arise.

CAPITAL RAISE

In May 2021, USF announced it had raised gross proceeds of $132 million in the Initial Issue of its 12-month Placing Programme announced in April 2021.

REFINANCING AND DEBT PAYDOWN

Shortly after the completion of the capital raising and consistent with the use of proceeds contemplated in the Company's Prospectus dated

13 April 2021, USF announced the refinancing of the existing debt facilities associated with the Heelstone Portfolio. The refinancing transaction used approximately $92 million of the $132 million gross proceeds of the Initial Issue along with the proceeds of a new debt facility provided

by Fifth Third Bank National Association to repay all of the existing project level debt. The new debt facility has a tenor of seven years but is fully amortised over approximately 17 years, to match the duration of the underlying PPA. Once completed, $7.6 million of restricted cash was released from the legacy debt providers and returned to USF.

The refinancing of these legacy loans reduces the effective interest rate for the Heelstone Portfolio from approximately 6.25% to less than 3% per annum. The base interest rate is fully hedged with fixed interest rate swaps for the full duration of the loan.

This refinancing will benefit USF by lowering overall gearing to approximately 40% (below the long-term target of 50%), reducing sensitivity to changes in key assumptions including long-term power prices, and enhancing dividend coverage.

An additional $7 million of proceeds was used to pay down debt on the Euryalus portfolio. The impact of these transactions is recognised in the movement in fair value of the Company's investment in its US subsidiaries and underlying Solar Assets. Note 13 to the Financial Statements shows the underlying movements on a look through basis for each of USF's Solar Assets.

PIPELINE UPDATE

The pipeline has remained robust since the Company's IPO ranging from US$1.9 billion to US$4.8 billion at any given quarter. As at 30 June 2021, the Investment Manager's pipeline included 2.2GWDC of high-quality assets (including Tranche Two of MS2), with an aggregate value of approximately $2.2 billion in cash equity value and a weighted-average PPA term of 15.2 years.

Throughout the course of the reporting period, the Investment Manager has screened over 7GWDC of projects, with a total cash equity value of over $7 billion. The Investment Manager continues to take a conservative approach to pricing. It also continues to strictly adhere to a process that is consistent with the strategy and return targets of the Company given the pipeline offers numerous high-quality construction-ready and operational investment opportunities, including the potential to install energy storage at existing sites.

EVENTS AFTER THE PERIOD

In August, the Investment Manager announced that John Martin would be stepping down as CEO to take up a position as CEO of Windlab Pty Ltd, a global renewable energy development company. Liam Thomas, previously CIO, was appointed as NESM's new CEO. Liam joined NESM in March 2016 and has overseen the acquisition and construction of utility-scale solar asset portfolios for USF and New Energy Solar, the Australian-listed fund also managed by NESM. Liam has 17 years of experience in the renewable energy, infrastructure, and agribusiness sectors including roles with Origin Energy, Aurizon, and Orica.

Subsequent to period end, USF reached agreement on all commercial terms to increase the size of the undrawn $25 million RCF to a $40 million facility, and extend the tenor for two years. Documentation is expected to be settled and executed in September 2021.

On 20 September 2021, the Company announced a dividend of 1.25 cents per Ordinary Share for the period ending 30 June 2021, bringing total dividends declared for the six-month period to 2.5 cents per Ordinary Share.

CORONAVIRUS

COVID-19 has had limited impact on the Company to date. Since the outbreak, USF has made changes to its work environment to ensure the health and safety of its employees, contractors, and stakeholders. The New York office is staffed on a limited basis with most of the US team working remotely using existing systems. The Sydney office has used staggered access arrangements to enable staff to work from the office while adhering to social distancing guidelines, except when lockdowns are in place.

The Investment Manager works with contractors and other stakeholders to ensure that operational targets are met while also meeting relevant COVID-19 requirements. Essential for economic activity, the generation and provision of electricity in most of the US has not been significantly disrupted by the pandemic. USF's projects have continued to operate and service personnel have been permitted to travel to sites to conduct work as needed. The Investment Manager continues to assess the current and potential impact of the COVID-19 measures implemented by the US federal and state governments on the Company's investment strategy and operations.

INVESTMENT PORTFOLIO

As at 30 June 2021 the Company owned 42 utility-scale solar projects, totaling 493MWDC. All assets in USF's portfolio have achieved commercial operations and are generating revenue for the Company. USF continues to assess new opportunities to add to the Company investment portfolio.

ACQUISITIONS

As of 30 June 2021, the Company had closed six acquisitions. Acquisitions One and Two completed in 2019, Acquisitions Three, Four and Five were completed in 2020 and Acquisition Six in 2021.

In March 2021, the Company announced it had completed the acquisition of the 25% interest in MS2 with an option to acquire a further 25%. As of 30 June, the total operational portfolio capacity of the portfolio reached 493MWDC as seen in Figure 4.

Table 4 shows USF's completed and committed acquisitions and valuation change between 31 December 2020 to 30 June 2021. Approximately US$92 million was invested over the period for the Heelstone Portfolio (Acquisition Four) Debt refinancing, resulting in an Acquisition Four valuation of $116.6 million as at the end of the period. Similarly, approximately US$7 million was used to repay debt on the Euryalus (Acquisition Five) portfolio, resulting in a valuation of $35.2 million as at 30 June 2021. As of the end of the period, the Fair Value of the portfolio acquisitions was $276 million.

Table 4: Portfolio Acquisition Valuation

INVESTMENT PERFORMANCE

At 30 June 2021, the Company's shares were trading at $1.015 per Ordinary Share. This represents a 7.6% premium to the NAV of $313.3 million or $0.943 per Ordinary Share. The NAV is defined as the total assets less any liabilities.

The Company generated a loss after tax of $4,985,055 (0.017 dollars per Ordinary Share) during the period. Intercompany loan interest income of $991,750, foreign exchange gains of $180,245 on funds that were retained in GBP, and MSA fee income of $2,568,123 from management services provided to the Fund's wholly owned US subsidiaries, were offset by a net loss from investments of $6,880,876 and administrative and other expenses of $1,844,297. The net fair value loss on investments arose from negative value impacts from updated merchant curves across the Fund's operating portfolio which offset positive value impacts due to the lower discount rates.

The financial statements of the Company are presented on pages 44 to 47. The Fund's sensitivity to discount rates and power prices is detailed below.

Table 5: Performance Summary

Figure 6 details the 3.4 cents per Ordinary Share movement in the "FV gain on solar investments" category shown in Figure 5. Discount rates were generally revised downwards to reflect current market rates, operational track-record, and capital structure, resulting in an uplift in valuations. The rollforward uplift is a result of bringing forward the valuation date to 30 June 2021, thereby removing cash flows from prior periods and bringing forward future cash flows. The adjustment to USF model reflects the updated valuation method to align with third-party valuation methods. To ensure alignment with these methods, the Investment Manager rounds valuations to the closest $0.5m, which resulted in a decrease this period. Net working capital adjusts for changes in project level cash, assets, and liabilities. The change in merchant curve reflects the update of forecast power prices to use the most recent two power price forecasts from two market consultants. Further details on the change in merchant curve can be found in the Valuation section below.

ONGOING CHARGES

The ongoing charges ratio of the Company is 1.36% of the average NAV for the period ended 30 June 2021. The ratio has been calculated using the AIC recommended methodology. The estimated total cost as laid out in the prospectus was 1.35% based on proceeds of $250 million.

The NAV for the period ending 30 June 2021 is $313.3 million.

The valuation of the Solar Assets produced by the Investment Manager is based on valuations by an independent appraiser on a semi-annual basis as at 30 June and 31 December. These valuations form part of the NAV calculation of the Company, which is subject to review/audit. Additionally, an unaudited NAV and NAV per Ordinary Share is calculated in US dollars on a quarterly basis as at 31 March and 30 September by the administrator, JTC (UK) Limited, (Administrator) in conjunction with the Investment Manager.

VALUATION METHODOLOGY

The Company has engaged an independent third-party appraiser to value operational Solar Assets acquired by the Company and its Project Special Purpose Vehicle (SPV), every six months as at 30 June and 31 December.

At each quarter end, the Investment Manager provides the relevant third-party or internal valuations of the Solar Assets, together with the valuations of the other assets of the Company and its Project SPVs, to the Company Secretary and Administrator of the Company.

The Administrator, in conjunction with the Investment Manager, calculates the NAV and the NAV per Ordinary Share as at the end of each quarter of the Company's financial year, and submits the same to the Board for its approval.

The valuation has been calculated in accordance with Uniform Standards of Professional Appraisal Practice (USPAP) as applied to PV electricity generation systems in the US.

Fair value for operational Solar Assets is derived from a discounted cash flow (DCF) methodology. For Solar Assets that are still under construction at the time of valuation, the purchase price of the Solar Power Asset including construction and acquisition costs is normally used as an appropriate estimate of fair value, provided no significant changes to key underlying economic considerations (such as major construction impediments or natural disasters) have arisen.

Primary valuation methodology:

• The equity fair values of USF's construction assets are based on the equity purchase price plus transaction costs (no assets were valued on this basis for 30 June 2021 as all assets were operational at period end).

• The equity fair values of USF's operational assets are based on DCF modelling of pre-tax cash flows to equity as at 30 June 2021. This methodology more accurately reflects the valuation impact of the discrete debt instruments that USF has in place when compared to an unlevered valuation.

• A post-tax valuation is conducted at the US Holding Corp. level to cross-check the implied post-tax discount rate.

In a DCF analysis, the fair value of the Solar Power Asset is the present value of the asset's expected future cash flows, based on a range of operating assumptions for revenues and costs and an appropriate discount rate range.

The Investment Manager has reviewed a range of sources in determining the fair market valuation of the Solar Assets, including but not limited to:

• discount rates publicly disclosed by the Company's global peers;

• discount rates applicable to comparable infrastructure asset classes; and

• capital asset price model outputs and implied risk premium over relevant risk-free rates.

A broad range of assumptions are used in valuation models. Where possible, assumptions are based on observable long-term historical market and technical data given the long-term life of the assets. The Investment Manager also engages technical experts such as long-term electricity price forecasters to provide long-term inputs for use in its valuations.

Long-term electricity price forecasts are obtained every six months from two leading independent power price forecasting firms for each jurisdiction in which Solar Assets are located. The most recent two electricity price forecasts from each firm are averaged and provided to the independent valuer to project the prices at which existing PPAs will be re-contracted. The averaging of curves and providers is used to prevent the valuation of the portfolio being unduly influenced by one forecaster's set of assumptions; to mitigate potential forecaster errors in a particular period; and to reduce the timing risk inherent in valuing the portfolio shortly before curve updates are released. The independent valuer assesses these forecast prices for reasonableness against their own internal forecasts and others in the marketplace.

The Investment Manager has used its judgement in arriving at appropriate discount rates which are consistent with the discount rates derived by the independent valuer. The Investment Manager's view of discount rates is based on its knowledge of the market, considering

intelligence gained from its bidding activities, discussions with financial advisers in the appropriate market, and publicly available information on relevant transactions.

30 JUNE 2021 VALUATION

NESM has engaged independent valuer KPMG to calculate the fair value of its operating renewable energy assets. KPMG is one of the largest valuation firms in the US with significant experience in estimating the fair value of solar and other renewable energy assets. In line with USF policy, 41 of USF's operating assets were externally valued at 30 June 2021 with MS2 held at cost given the transaction closed during the half-year period.

Figure 7: Merchant Electricity Power Price Forecast (Excluding Acquisition Six)

Figure 8: Movement In Portfolio Weighted Average Merchant Pricing (Excluding Acquisition Six)

 The Company's contracted cash flows during the PPA period are not impacted by any changes in merchant electricity price forecasts, however, these forecasts are used to estimate revenue received in the post-PPA period. The merchant electricity price forecasts used in the 30 June 2021 valuation declined approximately 10.1% across the portfolio compared with 31 December 2020, reflecting COVID uncertainty at the time these forecasts were released in 2020 and early 2021. This resulted in a reduction of $0.05 per share or 5.1% of NAV, consistent with the NAV sensitivity analysis published in our annual report.

The Company uses the average of the most recent two forecasts (available at the valuation date) from two independent providers (a total of four price forecasts). The most recent merchant electricity price forecast released by one of these providers (after the end of period) is, on average, 14.5% higher than the forecast it will replace in the 31 December 2021 valuations; due to a reduction in COVID-related sentiment and an increasingly bullish outlook for carbon pricing to 2050. The other independent provider will release an updated forecast prior to the 31 December 2021 valuation date.

The impact of merchant electricity price forecasts was partially offset by a gain of $0.028 per share from favourable reductions to discount rates reflecting the portfolio's continued transition from construction phase to full run-rate operations, as well as the reduction in leverage achieved through the refinancing of the Heelstone portfolio. The weighted average pre-tax cost of equity used for levered assets was

7.3% (December 2020: 8.3%), and the weighted average pre-tax weighted average cost of capital (WACC) for unlevered assets was 6.5% (December 2020: 6.7%). The largest driver of the reduction in pre-tax cost of equity was the Heelstone Debt Refinancing.

Reductions in discount rates typically occur as a project progresses from construction start to one full year of operations. As of June 30, 2021, the portfolio has reached run-rate operations except for our largest asset, Milford. The Company expects an incremental reduction in discount rate as the asset reaches a full year of operations during H2 2021.

TAX EQUITY

At a federal level in the US, the Investment Tax Credit (ITC) introduced in 2005 to give project owners tax credits for installing designated renewable energy generation equipment, has been highly successful in driving renewable energy adoption in the US. In addition, certain solar PV assets are eligible for accelerated depreciation, enhancing US tax effectiveness. At 30 June 2021, tax equity financing was in place for all projects in the Company's portfolio except for Acquisition Three. US tax equity structures customarily include a mechanism for the tax equity investor to exit the structure after a time or return-based target is met. As expected at the time of acquisition, US Bancorp fully exited the Acquisition Three tax equity structure during the period.

Table 6 below details the tax equity arrangements for the Company's portfolio.

Table 6: Tax Equity Summary

GEARING

On a look-through basis USF had outstanding debt of $202.5 million as at 30 June 2021, based on the face value of drawn debt. This equates to 39.3% of Gross Asset Value (GAV) (calculated as NAV plus outstanding debt).

Refer to Note 8 of the financial statements for further information on USF's debt facilities.

SENSITIVITY ANALYSIS

The Investment Manager and the Company use sensitivity analysis to assess the impact of changes in key assumptions on the fair value of the Company's investments. The sensitivities shown in Figure 9 assume the relevant input is changed over the entire useful life of each of the

underlying renewable energy assets, while all other variables remain constant. All sensitivities have been calculated independently of each other. The full sensitivity analysis, including comments on key assumptions and sensitivities, is included in Note 13 to the financial statements.

4. Environmental, Social and Governance

During the reporting period, the Company and Investment Manager focused on acquiring and operating assets, and in doing so, Environmental, Social and Governance (ESG) factors were taken into account.

The Company invests in and sells energy generated by Solar Assets to energy offtakers, directly contributing to renewable energy infrastructure and renewable power generation. As of 30 June 2021, USF's portfolio comprised 42 operational solar plants which are responsible for displacing more than an estimated 633,000 tonnes21 of CO2 emissions, equivalent to powering over 79,000 US homes, or removing over 137,000 US cars from the road every year.

Core to the Company's investment and environmental objectives is the intention to build a long-term, sustainable business. Accordingly, the Directors and the Investment Manager are committed to managing USF in line with the core principles of good ESG practices.

Investing in utility-scale solar to provide attractive risk-adjusted returns for investors is, by its very nature, a compelling investment for investors focused on sustainability and ESG. It contributes positively and materially to the world's growing awareness of and momentum to address the impact of human activity on the environment and climate. Importantly, through developing utility-scale solar projects and contracting the PPAs with various offtakers, the Company directly contributes to the share of renewable energy in the global energy mix.

In April 2021, the parent of the Investment Manager became a signatory to the United Nations sponsored Principles for Responsible Investing (UN PRI). This Company is also reviewing EU sustainability and ESG disclosure frameworks to see how they might best be applied to USF.

USF complied with pre-contractual disclosure requirements as part of our recent equity raising to meet the EU ESG disclosure obligations for EU-domiciled investors and prospective investors, and is considering aligning with EU reporting frameworks in 2022.

ESG DUE DILIGENCE AND ACQUISITION

• Environmental site assessments are completed for all assets during due-diligence and obtain certification that all projects comply with applicable local, state or federal law.

• Physical climate-related risks are considered during the diligence process and routinely throughout operations.

• O&M contractors and facility managers must obtain and maintain all permits required under applicable laws, including environmental regulations for each facility, and operate them accordingly.

• EPC contracts require third parties to conduct themselves and their processes to the highest standard of environmental control and compliance with all applicable laws. Strict controls are implemented to avoid any spill contamination, hazardous substances, trade sanctions in supply chains, and waste containment, among others.

• Prior to construction or investment, each solar asset site has, as part of the EPC contract, an agreed Health and Safety Plan that explicitly outlines health, safety and security measures to be employed and includes various state and federal laws to which all contractors, subcontractors, and site visitors must adhere, as well as injury reporting and investigation and corrective action processes.

ESG PRINCIPLES AT WORK IN USF

Adherence to ESG principles requires USF to consider the broader impact of its activities and to incorporate practices to further the aim of these principles.

Environmental considerations incorporate the impact on both the local environment, as well as global issues like climate change. USF's primary activity is investing in Solar Assets which support renewable energy development and provide a clean energy source to communities . Further, USF's strategy of owning and operating solar power portfolios directly contributes to the displacement of CO2 emissions and assists states in their transition to becoming low carbon economies, helping to achieve their respective renewable energy targets.

USF's positive environmental impact can be seen in USF's first acquisition, the Milford Solar project in Utah. This project generates over 277,500 megawatt hours of electricity annually. This volume of electricity is equivalent to displacing approximately 235,000 tonnes of CO2 emissions, powering 31,000 US homes, or removing 51,000 US cars from the road, every year.

The Company will often acquire plants that are not yet operational, and as such require many contractors and employees to construct each project. For example there were over 80 contractors on site for the construction of the 128MWDC Milford solar plant. The Company, through the engagement of its contractors, seeks to create quality jobs in the communities in which it operates. Once operational, the plants provide a smaller number of long-term employment opportunities for members of the communities in which the plants are located.

The Company is committed to making tangible contributions to the prosperity and economic development of the regions in which it operates. For example, the Company seeks to form open and strong relationships with the landowners on which its assets are located, as well as those near its assets. The Company also partners with educational and research institutions to share insights and data to further advance the solar industry.

These partnerships also help USF to continue to improve its practices around land preservation, a key consideration for the Company during an asset's construction phase and operational life.

Governance considerations require a company to examine its structure, leadership, shareholder rights and internal controls. USF's Board of Directors is independent of the Investment Manager and seeks to implement a system of rules and practices that preserves the integrity and efficiency of its operations. The Board has worked with the Investment Manager and Company Secretary to maintain a framework of governance to meet the interests of stakeholders including shareholders, customers, financiers, government, suppliers and the community. The Company also considers acquisition and asset management principles and practices as they relate to dealing with anti-corruption and labour standards.

USF recognises that these governance considerations are critical to building a successful, long-term business.

SITE-SPECIFIC ESG INITIATIVES DURING OWNERSHIP

As assets are onboarded and in-construction assets become operational, site-specific Key Performance Indicators (KPIs) are implemented based on a list of potential measures for each asset. The US is vast and contains many different ecological environments. The initiatives used for each site depend on the local environment as well as the size of the asset. As USF's solar assets range from 2MWDC to 128MWDC different measures are appropriate for different size assets. The list below includes actual measures that have been implemented at various USF sites (as noted in parentheses) and options that are being considered at other sites:

ENVIRONMENTAL

• Minimisation of water usage and monitoring consumption (all sites).

• Planting of local/indigenous grasses, plants or wildflowers (Milford, Benson, Eagle Solar, Lane II, Pilot Mountain, Tate, Willard).

• Implementation of sustainable drainage and flood control measures (Benson, Eagle Solar, Lane II, Pilot Mountain, Tate, Willard, Four Oaks).

SOCIAL

• Attendance at local community and government meetings to maintain community engagement and dialogue.

• Ongoing relationship development with O&M providers, construction contractors, and landowners to encourage local community engagement and contribution (all sites).

• Effective complaint reporting and handling (all sites).

• Engagement with local education institutions to help develop understanding of renewable energy (Alkali, Rock Garden, Suntex, West Hines I).

• Contributions to select local and regional charitable organisations (Granger, Alkali, Rock Garden, Suntex, Pilot Mountain).

• On site, all injuries and incidents must be reported immediately, and reporting is followed by a well-documented investigation process, detailed report, and corrective action (all sites).

GOVERNANCE

• Periodic and regular review of safety statistics and site visits with site service providers to ensure compliance with local and regional laws and the Investment Manager's ESG practices (all sites).

• Annual review of contract compliance (including health and safety plans) with site service providers (all sites).

• Regular review of site permits and obligations to ensure safe and effective operations within the regulatory guidelines (all sites).

SUSTAINABILITY

USF was established to both capitalise on and contribute to the world's increasing awareness of the impact of climate change and the need to better manage the world's resources for present and future generations. The Company is focused on sustainability, primarily as an investor in the solar industry, but also in the way the Company is managed.

ALIGNMENT WITH UNITED NATIONS SUSTAINABLE DEVELOPMENT GOALS (UNSDG)

In 2015, the United Nations (UN) developed 17 Sustainable Development Goals (SDG) to enable individuals, organisations, corporations, and governments to implement, record and measure their approach to addressing global challenges including poverty, inequality, and climate change.

The Company is aligned with the UNSDG and has selected two core goals to which the Company can most measurably contribute.

UNSDG 7. 2

The 42 solar power projects in USF's portfolio have a combined capacity of 493MWDC. This power is generated without producing emissions and importantly, also replaces fossil-fuel generated power, thereby displacing CO2 emissions. As USF's 42 assets are all operating, they will be responsible for displacing more than an estimated 633,000 tonnes22 of CO2, every year, equivalent to powering 79,000 US homes or removing 137,000 US cars from the road each year.

As a sustainably run business, USF is conscious of its obligations to carefully consider and plan for the future disposal of solar panels. Given USF's solar plants are relatively new, with only 8% of capacity (including all acquisitions) being operational for greater than five years and the majority being operational between two and five years, the business has not yet needed to manage the disposal of large quantities of solar panels, due to the assumed solar asset life of 35+ years per project. In any case, USF works with its contractors to ensure that materials and panels are disposed of or where appropriate recycled properly according to any associated regulations.

During construction and operation, the solar panels employed in USF's plants have proven to be robust and rates of damage and waste have been very low. With respect to the bulk of the panels installed at USF's solar power plants, USF intends to establish a solar panel recycling system that can facilitate the recovery of valuable secondary raw materials and promote high levels of reuse. To this end, USF is investigating the recycling programs available in the industry and the approaches of its development and construction partners.

UNSDG 8.8

When an acquired project is yet to be constructed, an Engineering, Procurement and Construction (EPC) Agreement must be agreed upon and signed before construction. This agreement contains a comprehensive and systematic Health and Safety Plan that explicitly outlines certain requirements according to each site location and layout of the project. This plan incorporates health, safety and security measures required by various state and federal laws to which all contractors, subcontractors and site visitors must adhere.

A site Health and Safety Committee is established for each project location, comprised of field representatives and management from the EPC contractor once construction commences. These representatives must obtain appropriate construction safety certification (known as "OSHA36") and are responsible for daily safety briefings. The representatives also facilitate weekly "toolbox" meetings, designed to address

potential safety concerns on-site, and ensure the implementation of preventive safety measures. USF did not have any assets under construction during the period.

Once a site is operational, and upon appointment of O&M contractors, a Safety and Health Management Plan is implemented. These plans provide personnel working at the site with a framework for addressing safety and health in the workplace with the goal of preventing any fatalities, injuries, illnesses and equipment damage. The approach is based on the principle that nearly all worksite fatalities, injuries and illnesses are preventable. USF currently has 42 operating projects.

The Company and the Investment Manager are also focused on injury reporting and investigation as they allow for review of existing preventive measures, thereby reducing the likelihood of an event occurring. All injuries and incidents must be reported immediately on the project site, followed by an investigation process, detailed report and corrective action.

Over the course of the period to 30 June 2021, there were no recordable injuries or lost-time accident on site.

The Company and Investment Manager continue to monitor and maintain health and safety management policies and take a preventive and proactive approach when dealing with health and safety hazards, rigorously implementing safety practices and improving them where applicable.

5. Principal Risks and Uncertainties

 The Board is responsible for financial reporting and controls, including the approval of the Annual Report and Accounts, the dividend policy, any significant changes in accounting policies or practices, and treasury policies including a use of derivative financial instruments.

The Company faces a broad range of risks that the Board and Investment Manager aim to mitigate through internal controls and other actions. These risks are regularly assessed on a periodic basis to ensure that the business operates smoothly and that any adverse effect on the Company's performance and share value is mitigated. To the extent possible, the Board also maintains a risk matrix that is reviewed annually under the risk management framework in place to minimise the impact of these risks should they occur. The risks that the Board and Investment Manager believe to be the most relevant to the business can be organised into key categories as set out below:

• legal & regulatory risks;

• financial & market risks; and

• operational risks,

Principal risks for the period and their mitigants are summarised in the tables below:

LEGAL & REGULATORY RISKS

FINANCIAL & MARKET RISKS

OPERATIONAL RISKS

LONGER TERM VIABILITY

The Board is responsible for financial reporting and controls, including the approval of the Annual Report and Accounts, the dividend policy, any significant changes in accounting policies or practices, and treasury policies including the use of derivative financial instruments. The Board of the Company is also required to assess the long-term prospects of the Company according to the Association of Investment Companies (AIC) Code. The Board has assessed the prospects of the group over a five-year period. The Board considers a five-year timeframe to be reasonable on the basis that the Company is in the initial stage of operating assets. The key risks facing the Company including, but not limited to, the risks mentioned on pages 26 to 28 have been individually assessed by the Board. The likelihood and impact of each risk on the Company prior to and after specific risk mitigation controls have taken place have been evaluated.

The Company owns a portfolio of Solar Assets in the US that are fully constructed, operational and generating renewable electricity. As a result, it benefits from predictable and reliable long-term cash flows and is subject to a set of risks that can be identified and assessed. Each Solar Asset is supported by a detailed financial model at acquisition and incorporated into the Company's valuation model for quarterly valuations, which are independently reviewed every half-year. The Board believes the diversification within the Company's portfolio of Solar Assets helps to withstand and mitigate the emerging and principal risks the Company is most likely to face. The Company's revenues from investments provide substantial cover to the operating expenses of the SPVs, USF Holding Corp., and the Company and any other costs likely to be faced by any of them over

the viability assessment period. The Investment Manager also prepares a rolling detailed monthly two-year cash flow forecast to address and specifically consider the sustainability of the dividends.

After assessing these risks, and reviewing the Company's liquidity position, together with the Company's commitments, available but undrawn credit facilities, and forecasts of future performance under various scenarios, the Board has a reasonable expectation that the Company is well positioned to continue to operate and meet its liabilities over the short term and the five-year outlook period. While the Board has no reason to believe that the Company will not be viable beyond the specified outlook period, it is aware that it is difficult to foresee the viability of any business over a longer period given the inherent uncertainty involved.

It is important to note that the risks associated with investments within the infrastructure sector could result in a material adverse effect on the Company's performance and value of Ordinary Shares. When required, experts will be employed to gather information, including tax advisers, legal advisers, and environmental advisers.

SECTION 172

Section 172 of the Companies Act 2006 recognises that directors are responsible for acting fairly as between members and in a way that they consider, in good faith, is the most likely to promote the success of the Company for the benefit of its Shareholders as a whole. In doing so, they are also required to consider the broader implications of their decisions and operations on other key stakeholders and their impact on the wider community and the environment. Key decisions are those that are either material to the Company or are significant to any of the Company's key stakeholders. The Company's engagement with key stakeholders and the key decisions that were made or approved by the Directors during the year are described below:

SHAREHOLDERS

The Company also relies on Shareholders for continued access to capital to support further growth of the Company.

The Investment Manager liaises with Shareholders through specified reporting of Company performance at set dates in the calendar, as well as ad hoc reporting of major announcements.

In addition, Shareholders have the opportunity to meet the Board at the Annual General Meeting (AGM). The Board also endevours to respond to any written queries made by Shareholders during the course of the period, or to meet with major Shareholders if so requested.

In addition to the formal business of the AGM, representatives of the Investment Manager and the Board are available to answer specific questions a Shareholder may have.

LENDERS

The Company also relies on Lenders for continued access to capital to support further growth of the Company, and to refinance existing debt facilities at maturity, or prior to maturity where it is accretive for Shareholders.

The Investment Manager liaises with Lenders through specified reporting of project level performance at set dates in the calendar, as well as ad hoc reporting of major announcements.

SERVICE PROVIDERS

Our service providers are fundamental to the quality of our product and to ensuring that as a business we meet the high standards of conduct that we set ourselves.

The Board meets at least annually to review the performance of the key service providers.

The Board has regular contact with the two main service providers: the Investment Manager and Administrator through quarterly board meetings with the Chair and Audit Chair meeting more regularly.

REGULATORS/GOVERNMENT

The Board regularly considers how it meets regulatory and statutory obligations and follows voluntary and best-practice guidance, including how any governance decisions it makes impact its stakeholders both in the short and long term.

PPA OFFTAKERS

The Offtakers for the Company's projects provide the main source of operating cash inflows to the Company. No Offtaker is a related party of the Board or Investment Manager. The Company is focused on ensuring assets operate in line with weather-adjusted expectations to deliver power to their PPA Offtakers.

LOCAL COMMUNITIES

The local communities, within which the Company's projects are based, provide local support as well as human resources to work on the project sites. The Company works actively with landholders and city councils, to resolve matters including egress and access, erosion, and land management issues.

6. Board of Directors

The Directors are responsible for the determination of the Company's investment objective and policy and its investment strategy and have overall responsibility for the Company's activities, including the review of investment activity and performance and the supervision and control of the Investment Manager. The Directors have delegated responsibility for managing the assets comprising the portfolio to the Investment Manager. Further information on the Board is provided at www.ussolarfund.co.uk.

9. Independent Review Report to US Solar Fund plc.

We have been engaged by the company to review the condensed set of financial statements in the half-yearly financial report for the six months ended 30 June 2021 which comprises the Condensed Statement of Profit and Loss and Other Comprehensive Income, the Condensed Statement of Financial Position, the Condensed Statement of Changes in Equity, the Condensed Statement of Cash Flows and related notes 1 to 17. We have read the other information contained in the half-yearly financial report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the condensed set of financial statements.

Directors' responsibilities

The half-yearly financial report is the responsibility of, and has been approved by, the directors. The directors are responsible for preparing the half-yearly financial report in accordance with the Disclosure Guidance and Transparency Rules of the United Kingdom's Financial Conduct Authority.

As disclosed in note 2, the annual financial statements of the company will be prepared in accordance with United Kingdom adopted International Financial Reporting Standards. The condensed set of financial statements included in this half-yearly financial report has been prepared in accordance with United Kingdom adopted International Accounting Standard 34, "Interim Financial Reporting".

Our responsibility

Our responsibility is to express to the Company a conclusion on the condensed set of financial statements in the half-yearly financial report based on our review.

Scope of review

We conducted our review in accordance with International Standard on Review Engagements (UK and Ireland) 2410 "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Financial Reporting Council for use in the United Kingdom. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK) and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the condensed set of financial statements in the half-yearly financial report for the six months ended 30 June 2021 is not prepared, in all material respects, in accordance with United Kingdom adopted International Accounting Standard 34 and the Disclosure Guidance and Transparency Rules of the United Kingdom's Financial Conduct Authority.

Use of our report

This report is made solely to the company in accordance with International Standard on Review Engagements (UK and Ireland) 2410 "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Financial Reporting Council. Our work has been undertaken so that we might state to the company those matters we are required to state to it in an independent review report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company, for our review work, for this report, or for the conclusions we have formed.
