INVESTMENT

POLICY

US Solar Fund plc (USF or the Company) is listed on the premium segment of the London Stock Exchange and

aims to provide investors with attractive and sustainable dividends with an element of capital growth by investing

in a diversified portfolio of solar power assets in North America and other OECD countries in the Americas.

OBJECTIVES

The Company acquires or constructs, owns and operates solar power assets that are expected to have an asset

life of at least 30 years and generate stable and uncorrelated cash flows by selling electricity to creditworthy

offtakers under long-term power purchase agreements (or PPAs).

INVESTMENT

MANAGER

USF is managed by New Energy Solar Manager, which was established in 2015 and has committed a total of more

than US$1.3billion to 57 utility-scale solar assets, 55 of which are in the US, totalling 1.2GW

HISTORY OF

THECOMPANY

The Company’s initial public offering (IPO) in April 2019 raised $200 million; the funds were all committed or

invested by December 2020 and the solar power assets were fully operational by that date. In May 2021 the

Company raised an additional $132 million as part of a 12-month Placing Program. The majority of the proceeds

have been used to refinance and reduce gearing on an existing portfolio. Subsequent to the period end, the

Company exercised its option to acquire an additional 25% of Mount Signal 2, committing a further $21 million.

PORTFOLIO

USF’s current portfolio consists of 42 projects across four US states with a combined capacity of 543

megawatts (MW

). Its assets are fully operational, generating 851 gigawatt-hours (GWh) over the period

Power offtake agreements are in place for 100% of generation with creditworthy counterparties with a weighted

average remaining life of 14.4 years

, providing a resilient and uncorrelated income stream.

TARGET RETURN

USF aims to deliver an annual cash-covered dividend of 5.5 cents per share, growing at 1.5 to 2% per annum,

foreach financial year from and including 2021.

1. Includes the option over the second 50MW

of MS2 exercised in February 2022.

2. Includes reimbursed curtailment.

3. Remaining PPA term from 31 December 2021.

2. Chair’s Statement

Davis Lane 7MW

I am pleased to present the Annual Report for US Solar Fund plc for the period ended 31 December 2021. This year was an exciting one for the

Company as it continued to deliver on its targets. During the course of the year the Company increased its market capitalisation by 66% following

a successful fund raising. In addition, it completed its first full year with the entire portfolio operating and paid the full target dividend totalling

5.5 cents, in line with the targets set out at and since IPO. This happened against the backdrop of increasing support for the solar industry in the

United States at many levels, most markedly at the federal level, with the Biden Administration taking office. The Board remains confident that the

US solar market is robust and that USF is well positioned to be a significant growth player as the US makes a push toward growing its reliance on

renewable energy.

Recently, the urgency of the shift to renewable power has been reinforced by the energy crisis provoked by the tragic events in Ukraine and its

knock-on effect on oil and gas prices. With oil prices increasing over 50% in the last three months, events such as this highlight one of the key

advantages of solar and other renewable energy in that it is not directly exposed to fuel price fluctuations. With global electricity prices still

largely driven by gas pricing, current high fuel prices are likely to feed through to higher short-term electricity prices, however it remains to be

seen how significant the impact will be on long-term electricity prices.

Throughout the period, USF shares have traded between $0.96 and $1.09 on the London Stock Exchange. At 31 December 2021, the Company’s

shares were trading at $0.96 per Ordinary Share. This represents a 1.6% discount to the NAV of $324.0 million or $0.975 per Ordinary Share, but

a 1.4% premium to the published 30 September NAV of $0.947 per Ordinary Share. Including dividends paid and reinvested during the period,

shareholder total return from inception to 31 December is 3.13%.

PORTFOLIO DEVELOPMENTS

In March 2021 and February 2022, USF acquired a total of 100MW

or 50% of a 200MW

project in California called Mount Signal 2 (MS2)

across two transactions each of 25%

. MS2 was built during 2018 and 2019 by Swinerton Renewable Energy, a leading US constructor, and has

a 20-year PPA with Southern California Edison (SCE), that commenced in June 2020. Under the PPA, 100% of the electricity generated by MS2

is sold to SCE at an annually escalating price. SCE (S&P: BBB), a subsidiary of Edison International, serves a population of more than 15 million

people and is the primary electricity provider for central, southern and coastal California.

As of 31 December, the portfolio comprised 493MW

across 42 fully operating projects in four states. All projects have investment grade PPAs

for 100% of electricity generated, and the weighted average remaining PPA of portfolio is 14.4 years. Including the purchase of 25% of MS2 after

the period, the portfolio totals 543MW

The full year’s generation (including nine-months generation from the first 25% tranche of MS2) was 3.9% below budget. 1.5% of this was due to

lower-than-expected irradiance and 2.4% from a combination of the contractually allowable and expected curtailment at MS2 in California during

the first half of the year, isolated performance issues, unplanned outages, snowfalls, and other adverse weather impacts. Maintenance and repair

of the issues impacting performance have been largely resolved with two smaller issues on track to be completed by spring 2022. The strong

geographic diversification of the assets benefited the portfolio through the year.

Dividend cash cover remained strong at 1.82x for the twelve months ended 31 December 2021.

CAPITAL RAISING AND USE OF PROCEEDS

We were delighted by the market response to the capital raising in May 2021 for $132 million with strong support from existing and

newinvestors.

Just after the capital raise, $92 million

was invested in the refinancing and de-gearing of the existing debt facilities associated with the

177MW

portfolio of 22 projects acquired in 2020 (Heelstone Portfolio and Heelstone Refinancing). The Heelstone Refinancing reduces

the effective interest rate for the Heelstone Portfolio from approximately 6.25% to less than 3% per annum with fund gearing approaching

40%, below the long-term target of 50%. A further $21 million was committed in February 2022 (after the period) to acquire an additional 25%

(TrancheTwo) of MS2.

2. Chair’s Statement

US SOLAR FUND PLC Annual Report and Financial Statements

9. USF has exercised its option over the second 25% tranche. Financial close will occur following customary financier consents and regulatory approvals.

10. USF used approximately $92million for the Heelstone Refinancing however approximately $7.6million was subsequently released from reserve

accounts held by the legacy debt holders resulting in a net use of proceeds of approximately $85million.

The Investment Manager has remained focused on delivering on the Company’s investment thesis and growing the portfolio in line with return

targets. The strong pipeline of assets for suitable investments includes standalone solar projects, integrated solar and battery storage projects,

and solar expansion and/or battery installation opportunities at existing sites. The Board and the Investment Manager are conscious of the need

to grow the Company. Hence as well as continuing to originate opportunities in mature US state solar markets, the Investment Manager is actively

broadening its focus within the existing mandate to include emerging US state solar markets, multi-offtake arrangements, distributed generation,

and suitable co-investment opportunities.

PERFORMANCE

USF’s audited NAV at 31 December 2021 was $324.0 million or $0.975 per Ordinary Share, a 1% increase of the 31 December 2020 NAV of

$0.970 per Ordinary Share. The NAV reflects the impact of useful life extensions for selected assets in the portfolio, and an uplift in the valuation

of USF’s interest in and option over MS2. The work on the useful life extensions was undertaken by an independent engineering firm, who looked

at each project in detail to assess the appropriateness of the extension. The asset life extensions and uplift in MS2’s valuation more than offset a

softer average long-term electricity price outlook, that pertained at the end of December 2021, as well as tax and working capital adjustments,

and valuation roll forward.

The NAV also includes the positive impact of discount rate reductions reflecting current market rates, maturing operational track-records, and

de-geared capital structures. This kind of NAV accretion is indicative of USF’s strategy to de-risk the portfolio by identifying opportunities to

improve capital structures and by purchasing assets at construction ready or in early operations and taking them into steady operations.

DIVIDEND

The Company declared a dividend of 1.5 cents per Ordinary Share in March 2022 for the quarter ending 31 December 2021, bringing the full

year 2021 dividend to 5.5 cents per Ordinary Share, completing its first year of operations with the full target dividend.

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 broadly reflects this seasonality of the Company’s underlying cash flows.

OUTLOOK

The US Solar Market continued remarkable growth during 2021. In late January, Wood Mackenzie released data showing that approximately

7.5GW

of utility-scale solar is expected to come online in Q4 2021, bringing the total 2021 forecast to be 20.2GW

up 30% from 2020’s

14.3GW

of installations. Wood Mackenzie expects challenges around commodity prices and supply chain constraints until early 2023 and

have reduced their 2022 forecast of utility scale solar installations by 7.5GW

(33%). Despite these headwinds, Wood Mackenzie still expects

approximately 122GW

of solar to be installed between 2021 and 2026.

In early 2021, the Biden Administration took office in the US and is working hard to push for more renewable energy through legislation. Although

the Build Back Better Act has not been able to get through the US Senate, there is an expectation that it will be reshaped and that some of the key

clean energy and climate initiatives will pass in a modified form. Wood Mackenzie’s forecasts expect the current ITC extension terms will boost

Solar capacity by 31% in the next five years (43.5GW

). The global supply chain constraints that are impacting all industries are also putting

pressure on the pace of solar development and the ITC extension would be expected to partially offset these impacts.

As we look at the current administration’s ambitious goal of shifting toward clean energy – 100% by 2035 – we believe that solar is set to play

a critical part. The US Department of Energy has said that in order to support initiatives around clean energy, solar could become 40% of US

electricity generation in the next 13 years. According to the EIA, the US generated roughly 3% of electricity from clean energy in 2020, requiring

significant investment and development in the coming years if the Biden administration is to meet its goals.

Although USF as a producer of renewable energy is well aligned with Sustainability and Environmental, Social and Governance (ESG) goals and

considerations, we also recognise the need to review and report on all aspects of the way we conduct business and to share our findings in a clear

and transparent way. Since IPO, USF has reported on Sustainability and ESG through its annual and interim reporting. In April 2021, the parent

of the Investment Manager became a signatory to the United Nations sponsored Principles for Responsible Investing (UN PRI); reporting will

commence in 2023 based on recommendations from the UNPRI.

US SOLAR FUND PLC Annual Report and Financial Statements

In February 2022, after the end of the period, USF published its first annual Sustainability Report covering 2021 and included initiation of USF’s

reporting through the Sustainable Financial Disclosure Regulation (SFDR) Annexe One. In the ESG section of this Annual Report, we also now

begin to include reporting with guidance from the Task Force on Climate-related Financial Disclosures (TCFD). We recognize that ESG and

Sustainability reporting is an evolving, dynamic space and our reporting will continue to adapt to incorporate new best practices in the coming

years. Though we will continue to include updates and disclosures as appropriate in the annual and interim reports, the majority of reporting will

be housed in the Sustainability Report, allowing us to meet the growing needs for greater transparency and depth in the reporting on these topics.

2022 has had a volatile start; with the abhorrent war in Ukraine, destabilising energy supply and the world in general. Of course, we are yet to

see the full repercussions of the conflict across the globe and across industries but the trajectory seems set for higher energy prices and stronger

demand for renewables. We do not yet know how these will affect longer term power prices but it would seem unlikely that the recent trend of

softening power prices will be maintained.

Despite the volatility and inflationary pressures in the broader markets, USF continues to deliver steady cash flows given its long-term PPAs held

by the portfolio of high-quality US solar projects. We are also pleased to have continued growing the portfolio, increasing capacity by 100MW

over the last year. The assets we currently own are fully operating with strong diversification across geographies and investment-grade offtakers

and a weighted average PPA term remaining of 14.4 years. Our debt facilities are protected against interest rate volatility through our strategy

of hedging all base interest rate risk on amortising debt for the full amortisation period. As an established investor, owner and operator in the US

solar market, we are well positioned to support the growth of the solar industry in the years to come. The Board and the Investment Manager

remain focused on delivering steady cash flows from the existing portfolio of assets, whilst looking for suitable opportunities in solar and storage

to grow the Company.

3. Investment Manager’s Report

SUMMARY OF THE PERIOD

During the year the Investment Manager has continued growing USF by completing the capital raise and the acquisition of 25% of MS2,

optimising USF’s financing structure, maximising operating efficiency across the portfolio and meeting and cash-covering the dividend target. All

cash flows from USF’s assets are contracted in the US with investment-grade offtakers for a weighted average remaining term of 14.4years

2021 was the first 12-month period when all assets were fully operating, and USF commenced paying the full target dividend. USF’s Q1 and Q2

2021 dividends were 1.25 cents per share and Q3 and Q4 2021, which is announced with this report, were 1.5 cents per share, totalling 5.5 cents

per share for the period and meeting the Company’s target full year dividend. Coverage of dividends paid during the year by free cash flow and

any cash flows carried forward was 1.82x, and the Investment Manager expects to continue to fully cash cover dividends paid in 2022.

In May, USF successfully closed an Initial Issue which was 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 177MW

portfolio of 22 projects acquired in 2020 (the Heelstone Portfolio). This refinancing benefits USF by

lowering overall gearing towards 40% (below the long-term target of 50%), and reducing sensitivity to changes in key assumptions including long-

term power prices, and enhancing dividend coverage.

In March 2021 and February 2022, USF closed two transactions, each a 25% stake in the 200MW

MS2 project in California adding 100MW

to the portfolio and bringing the portfolio to 42 assets across four US states totalling 543MW

The various strains of COVID-19 which evolved during the year had no material impact on USF’s operations or portfolio during the

reportingperiod.

NAV

The Company’s NAV per share increased from $0.97 per share on 31 December 2020 to $0.975 per share on 31 December 2021, reflecting the

combined impacts from asset life extensions and an uplift in the valuation of USF’s initial investment in, and option over, MS2 less dividends paid

and operating costs. The Investment Manager engaged independent engineers and independent valuers who supported the Manager’s proposed

asset life extensions for 30 of 42 assets in the portfolio. The asset life extension process is further described in the Investment Performance

section of this report.

NAV was also positively impacted by discount rates which were generally revised downwards to reflect current market rates, maturing

operational track-records, and de-geared capital structures, resulting in an uplift in valuations. MS2’s equity valuation increased from its

acquisition valuation reflecting performance more aligned with run-rate expectations, longer operating history, and general market conditions.

This is consistent with USF’s strategy of acquiring construction ready or early stage operating assets and achieving valuation uplifts through de-

risking the portfolio.

PORTFOLIO UPDATE

After the close of the period, USF exercised its option over Tranche Two of MS2 for $21 million. The Tranche Two purchase was subject to an

operational performance-based adjustment mechanism.

As noted above, the MS2 acquisitions increase USF’s total portfolio to 543MW

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 in its robust pipeline to add to the portfolio, including consideration of

storage and solar expansion opportunities at existing sites.

Actual Generation (includes reimbursed curtailment) Budgeted Generation

Figure 2 above shows actual and budgeted generation from the assets in the portfolio for the four quarters in the period. The increase in

production from Q1 to Q2 and decrease from Q3 to Q4 is largely attributable to the seasonality of production as we moved into and then out of

the summer months.

13. Underlying solar assets are held by subsidiaries via various structures including trusts and partnerships.

14. Includes reimbursed curtailment. Curtailment is when a plant is directed to reduce generation due to grid constraints or lower than expected

electricitydemand.

The portfolio performed 3.9% below budget for the year, with actual production of 851GWh (including reimbursed curtailment) versus the

budgeted or forecast production of 885GWh; as shown in Figure 3 below, 1.5% of this was due to lower-than-expected irraiance and 2.4% due

to a combination of H1 curtailment at MS2 in California (0.5%), isolated performance issues (0.7%), unplanned outages (1.2%), and soiling (0.2%),

being partially offset by other net impacts of 0.1%.

Construction for all USF projects was completed by the end of 2020, and the period ending 31 December 2021 was the first year the entire

portfolio was fully operational. During the period, USF completed the acquisition of 25% of MS2, adding 50MW

of capacity to the portfolio

from the start of the second quarter.

NORTH CAROLINA

The North Carolina portfolio (34% of total MW and 28% of budget MWh) performance was 5.5% below budget. Performance was impacted by a

number of small site-specific issues including grid outages and unscheduled maintenance. All identified issues have been resolved.

OREGON

The Oregon portfolio (28% of total MW and 27% of budget MWh) performed 3.7% below budget primarily due to poor weather (including

snow), grid outages (partially driven by the Oregon wildfires, although no sites were damaged by fires), soiling and unscheduled maintenance. All

identified issues have been resolved except damaged feeder cables (rodent damage at Chiloquin, 14.0MW

), which are expected to be repaired

this spring; the Investment Manager has filed an insurance claim for repair costs and business interruption.

US SOLAR FUND PLC Annual Report and Financial Statements

UTAH

In Utah, Milford (26% of total MW and 31% of budget MWh) performed 1.1% below budget for the year. Although the project performed strongly

above budget for the first half of the year, inverter and medium voltage transformer issues drove underperformance in August and September. All

identified issues have now been repaired under warranty and the project is performing well.

CALIFORNIA

Performance in California (12% of total MW and 14% of budget MWh) for the year was 6.9% below budget largely due to soiling, curtailment,

grid outages and unscheduled maintenance at MS2 (50MW

). MS2 experienced roughly two full years of expected curtailment within the 2021

calendar year (the curtailment calendar is June to May). While the curtailment was budgeted for by the Investment Manager, it was expected to

be spread evenly across twelve months for each year. MS2’s soiling and sensor issues are expected to be resolved by the end of March 2022.

CAPITAL RAISE AND USE OF PROCEEDS

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

2021. The raising was oversubscribed and received strong support from existing and new investors.

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

13April 2021, USF completed 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 and is partially

amortised over this period. These amortisation payments are consistent with an anticipated full amortisation schedule out to 2037, which is

slightly shorter than the tenor of the project's underlying aggregated PPAs. This full amortisation profile is reflected in the fixed-for-floating

interest rate swap which is in place to hedge the floating rate risk on the anticipated debt profile.

The refinancing reduced 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. It also lowered overall gearing for USF to 38.4%

(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 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 17 to the Financial Statements shows the

underlying movements on a look through basis for each of USF's Solar Assets.

In February 2022, USF exercised its option over Tranche Two, committing an additional $21 million of the capital raise proceeds.

PIPELINE UPDATE

At 31 December 2021, the Investment Manager’s pipeline included 1.9GW

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 17.7 years.

During 2021, the Investment Manager screened over 13.4GW

of solar projects, with a total cash equity value of over $12.8 billion. Among

these projects, the Investment Manager has screened an increasing number of opportunities that include an energy storage component. The

Investment Manager has commenced assessing projects in the portfolio for suitability of retrofit battery storage and will continue to work with

specialist energy storage consultants in 2022. As well as continuing to originate opportunities in mature US state solar markets, the Investment

Manager is actively broadening its focus within the existing mandate to include emerging US state solar markets, multi-offtake arrangements,

distributed generation, and suitable co-investment opportunities.

The Investment Manager continues to take a conservative approach to valuation of acquisition opportunities. It also continues to strictly adhere

to a process that is consistent with the strategy and return targets of the Company. While the Investment Manager has observed an increasing

level of competition for large-scale solar assets in 2021, the Company was successful in increasing the portfolio by 100MW

including the

exercise of the option for Tranche Two of MS2 (50MW

) post year end.

In September 2021, USF increased the size of the undrawn $25 million RCF to a $40 million facility and extended the tenor for two years. As of

the date of this report, the RCF remains undrawn, which alongside investible cash on hand following the acquisition of Tranche Two of MS2, is

available to fund suitable pipeline opportunities.

15. USF used approximately $92million for the Heelstone Refinancing however approximately $7.6 million was subsequently released from reserve accounts

held by the legacy debt holders resulting in a net use of proceeds of approximately $85 million.

As at 31 December 2021 USF had invested $283 million in the operating portfolio. On 10 February 2022, USF exercised its option to acquire

Tranche 2 of MS2, which will require an additional $21million to be funded from cash on hand. Following the acquisition, USF is forecast to have

$16million of investible cash remaining, which is intended to be used for further acquisitions or storage opportunities.

EVENTS AFTER THE PERIOD

As noted above, in February 2022, USF announced it had exercised its option over Tranche Two of MS2, bringing USF’s ownership of the project

to 50% (100MW

On 24 March 2022, the Company announced a dividend of 1.5 cents per Ordinary Share for the period ending 31 December 2021, bringing total

dividends declared for the twelve-month period to 5.5 cents per Ordinary Share, meeting the dividend target. The dividend is expected to be paid

on or around 29 April 2022.

CORONAVIRUS

USF continues to operate well during the COVID-19 pandemic, with no material impact on the Company to date. USF continues to adjust its

work environment to ensure the health and safety of its employees, contractors, and stakeholders. Both the New York and Sydney offices

of the Investment Manager have arrangements that adhere to local guidelines including limited staffing, remote work and staggered access

arrangements as and when needed. The Investment Manager also recently moved to larger premises in New York to accommodate increased

distancing between team members. As the Board and Investment Manager have been accustomed to working across three continents since

inception, remote meetings and communicating across time zones and flexibility were already efficiently managed by all parties.

The generation and provision of electricity in most of the US has not been significantly disrupted by the pandemic as it has consistently been

considered an essential service. With construction completed, USF’s projects have continued to operate and service personnel have been

permitted to travel to sites to conduct work as needed, with no material supply chain impacts for spare parts. 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.

Table 4 shows USF’s completed and committed acquisitions and valuation change between 31 December 2020 to 31 December 2021.

Approximately $92 million

was invested over the period for the Heelstone Portfolio (Acquisition Four) debt refinancing, resulting in an

Acquisition Four valuation of $119.7 million as at the end of the period. Similarly, approximately $7 million was used to repay debt on the Euryalus

(Acquisition Five) portfolio, resulting in a valuation of $36.7 million as at 31 December 2021. Milford (Acquisition 1) and MS2 (Acquisition 6)

also saw an uplift in valuation across the period primarily due to cost of capital rerates. As of the end of the period, the Fair Value of the portfolio

acquisitions was $289 million.

A detailed summary of the movement during the period can be found in Note 17 to the financial statements.

INVESTMENT PERFORMANCE

At 31 December 2021, the Company’s shares were trading at $0.96 per Ordinary Share and have continued to trade around this level since year

end. This represents a 1.6% discount to the 31 December 2021 NAV of $324.0 million or $0.975 per Ordinary Share. The NAV is defined as the

total assets less any liabilities.

The Company generated a gain after tax of $14,954,943 ($0.052 per Ordinary Share) during the period. Intercompany loan interest income

of $1,988,957, foreign exchange gains of $106,649 on funds that were retained in GBP, US distributions of $2,996,992, MSA fee income of

$4,673,924 from management services provided to the Fund’s wholly owned US subsidiaries, and a net gain on investments of $9,118,692, were

offset by administrative and other expenses of $3,930,271. The net fair value gain on investments was attributable to updated discount rates,

useful life revisions and an increase in value on the MS2 option as detailed in Figure 6.

The financial statements of the Company are presented on pages 82 to 85. The Fund’s sensitivity to discount rates and power prices is

Figure 7 details the 1.8 cents per Ordinary Share movement in the “FV gain on solar investments” category shown in Figure 6. The roll forward uplift

is a result of bringing forward the valuation date to 31 December 2021, thereby removing cash flows from prior periods and bringing forward future

cash flows. This resulted in a slight decrement across the portfolio this period due to the cash flow profiles of Granite, Heelstone, and Euryalus.

Discount rates were generally revised downwards to reflect current market rates, maturing operational track-records, and de-geared capital

structures, resulting in an uplift in valuations. MS2’s (Acquisition Six) equity valuation increased from its acquisition valuation primarily due to an

updated discount rate to reflect improved operating performance more aligned with run-rate expectations, longer operating history, and general

market conditions.

USF engaged a leading independent engineer (IE) to review portfolio useful lives, which resulted in 30 of the 42 assets having their useful

lives extended to 40 years. The IE reviewed the geotechnical and structural design, historical operational performance, budgeted operating

costs, and other key components to determine a recommended useful life and associated assumptions, including additional maintenance and

capital expenditure. Assets that were considered for extensions have permits, contracts, and land control to support the term of useful life. The

Investment Manager’s extension of useful lives was independently reviewed by both the Company’s external engineer and valuer along with it

being considered as part of the fair value of the Company’s investments in the auditor’s report accompanying the financial statements.

The uplift in MS2’s valuation as at 31 December 2021 has also increased the value of the Company’s Tranche 2 option to acquire a further 25%

stake in MS2 as reflected in the 1.6c uplift in the waterfall. Post-period end, the Company announced that it had exercised this option.

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. Over the course of 2021, independent forecasts of merchant prices have generally been revised downwards, resulting in a negative impact

on NAV. Further details on the change in merchant curve and the impact on the Company’s investments can be found in the Valuation section below.

The adjustment to USF model reflects the updated valuation method to align with third-party valuation methods, noting the Investment

Manager’s valuation for each asset (and therefore on a portfolio basis) are within the valuation ranges prepared by the independent valuer.

Net working capital adjusts for changes in project level cash, assets, and liabilities, and the change in transaction costs reflects actual acquisition

and capital raise costs incurred during H1 2021 compared to forecast.

ONGOING CHARGES

The ongoing charges ratio of the Company is 1.36% of the average NAV for the year ended 31 December 2021. The ratio has been calculated

using the AIC recommended methodology.

VALUATION

NET ASSET VALUE

The NAV for the period ending 31 December 2021 is $324.0 million, or $0.975 per Ordinary Share.

US SOLAR FUND PLC Annual Report and Financial Statements

The valuation of the Solar Assets produced by the Investment Manager fully takes into account the overall valuations by an independent appraiser

on a semi-annual basis as at 30 June and 31 December. The Company’s valuations are within the valuation ranges of the independent appraiser.

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 31 December 2021 as all assets were operational during the period and 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 31 December 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, and for the current valuation cycle an independent engineer, to provide or validate 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.

The Investment Manager 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, all 42 of USF’s operating assets were externally valued at 31 December 2021.

31 Dec 2021 Valuation Merchant Pricing

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 impact of merchant electricity price forecasts was partially offset by a gain of $0.037 per share from favourable reductions

to discount rates reflecting the portfolio’s maturing full run-rate operations, improved operating performance, as well as the reduction in leverage

achieved through the refinancing of the Heelstone portfolio and the repayment of debt on the Euryalus portfolio. The weighted average pre-

tax cost of equity used for levered assets was 7.8% (December 2020: 8.3%), and the weighted average pre-tax weighted average cost of capital

(WACC) for unlevered assets was 6.3% (December 2020: 6.7%). A driver of the reduction in pre-tax cost of equity was the Heelstone Debt

Refinancing. In addition, reductions in discount rates typically occur as a project progresses from construction start to one full year of operations.

MS2 (Acquisition Six) saw an equity valuation increase from its initial acquisition cost primarily due to an updated discount rate to reflect improved

operating performance more aligned with run-rate expectations, longer operating history and general market conditions.

The Investment Manager conducted a useful life analysis with a reputable IE in December 2021. The Investment Manager has historically relied

on IE support and recommendations for useful life of the projects in our portfolio. Many of the assets within USF’s portfolio are contractually

able to support a longer useful life so long as the project can support it technically and structurally. The Investment Manager initially reviewed

the projects in the portfolio that had adequate contractual protections to support a longer useful life such as land control and interconnection

terms. The IE then reviewed geotechnical and structural design, major equipment, material selection, historical operating performance, budgeted

operating costs and future forecasts, and other key technical inputs to assess the useful life and provide additional assumptions that would need

to be included in the models to support it. As a result of the analysis, 30 of 42 assets within USF’s portfolio had their operating lives extended to

from 35 to 40 years from commencement of commercial operations. The useful life extensions resulted in a NAV uplift of $0.045 over the period.

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 31 December 2021, tax equity financing was in place for

all projects in the Company’s portfolio except for Granite (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. For valuation purposes, the Investment Manager assumes tax

equity partners exercise their purchase or withdrawal options at the earliest possible date, and as expected at the time of acquisition, US Bancorp

fully exited the Granite (Acquisition Three) tax equity structure during the period.

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

GEARING

Taking the US operating subsidiaries and holding companies into account (which we also refer to as being on a look-through basis), USF had

outstanding debt of $201.9 million as at 31 December 2021, based on the face value of drawn debt. This equates to 38.4% of Gross Asset Value

(GAV) (calculated as NAV plus outstanding debt). This is below USF’s long-term target of 50%.

Refer to Note 10 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.

INFLATION

Rising inflation became a key area of focus in the US during 2021. USF considers inflation in terms of potential impact on cash flows from the

existing portfolio, NAV, and pipeline opportunities.

For the existing portfolio, which is fully operational, the Company is protected from near-term increases in capital and operating costs. While

replacement of equipment in the near-term is unlikely given the age of the portfolio, any required near-term equipment replacements are

expected to be under manufacturer warranties. Contracted operating costs such as operations and maintenance (O&M) and asset management

are fixed under the terms of the Company’s contracts with third party providers for terms of one to four years and are often subject to extensions

at predetermined pricing independent of inflation. Given this, along with increasing competition and continued efficiency gains in the solar O&M

and asset management market, upcoming renewals are expected to be at the same, or lower, pricing. In terms of revenue, although USF’s PPA’s do

not contain direct inflation linkages (which are uncommon in the US), some of the contracts escalate at a specified percentage annually.

In terms of NAV, in an inflationary environment USF would expect the discount rates used in valuation to increase. However, the price at which

the projects can re-contract or sell electricity after the PPA period expires could also be expected to increase with higher inflation and interest

rates, which would partially offset the impact of higher discount rates. Base interest rates on the Company’s drawn amortising debt facilities are

fully hedged for the term of the relevant loan, and for one or more subsequent re-financings.

For pipeline opportunities, higher raw material prices for new projects mean those projects need higher revenues to earn the same return. This

could see some future projects delayed until economics improve however, given the already competitive economics of solar, this is expected to be

a very small number and, importantly, USF does not invest until PPA prices and construction costs are certain .

SHARE CAPITAL

ESG AND SUSTAINABILITY REPORTING DEVELOPMENTS

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. The Company’s Board and Investment Manager are committed to providing

transparent, and thorough reporting on ESG and Sustainability, and will regularly review new frameworks and initiatives that may improve or

refine USF’s approach.

Since its 2019 IPO, USF has consistently reported on ESG and Sustainability considerations throughout its interim and annual reports. In

February 2022, the Company published its first annual Sustainability Report covering 2021, which forms part of the Company’s reporting on the

Taskforce on Climate-related Financial Disclosures (TCFD). The USF Sustainability report included and also expanded on existing frameworks

like the United Nations Sustainable Development Goals (UN SDG), adding detailed descriptions of Environmental, Social, and Governance

considerations and initiating reporting within the European Union Sustainable Financial Disclosure Regulation (EU SFDR) Annex One framework.

Although USF is not required to report through the SFDR framework, the Board and Investment Manager recognise the value of the framework

broadly and the specific relevance to EU based investors who support USF. Key ESG and Sustainability metrics will be mentioned in the Annual

and Interim Reports while fulsome reporting will be captured in the Sustainability Report.

In April 2021, the parent of the Investment Manager became a signatory to the United Nations Principles for Responsible Investing (UNPRI)

and mandatory reporting will commence in 2023 (a slight delay to typical timelines given a change in systems at the UNPRI organisation). As a

signatory, the Company’s Investment Manager has committed to incorporating ESG issues into their policies and practices and also to seek and

promote appropriate ESG disclosures.

The Board and Investment Manager have commenced reporting against the TCFD framework in this annual report, referring to the Company’s

Sustainability Report where relevant disclosures have been made in that document. We believe that the TCFD framework will further assist investors

and other market participants to review and understand USF’s approach and consideration of ESG and Sustainability risks and opportunities. This is

our first time engaging with the framework, and we recognise that over time we will continue to refine and expand our reporting. We have included

our responses to the framework below in addition to our regular reporting on Principal Risks and Uncertainties in the following section.

USF’S TCFD REPORTING (CLIMATE CHANGE RELATED RISKS ANDOPPORTUNITIES)

As mentioned above, 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. This is the principal way in which the Company engages

with opportunities related to climate change. The Company is focused on sustainability, primarily as an investor in the solar industry, but also in

the way the Company is managed as discussed below.

The disclosures on the following pages report against all 11 of the TCFD recommendations. USF has complied with LR 9.8.6R by including

climate-related financial disclosures consistent with the recommendations, other than including integrated climate related risk scenarios and

emissions reporting, which will be incorporated in future reporting.

Governance Disclose the organisation’s governance around climate-related risks and opportunities.

1. Describe the board’s

oversight of climate-related

risks and opportunities.

The USF Board has overall responsibility and oversight of risks and opportunities, which includes climate-

change. The Board comprises four independent directors each with different and complementary

backgrounds and valuable industry and investment trust experience as well as demonstrated stewardship

and governance excellence. The strength of USF’s Board, particularly around governance, sustainability

and clean energy robustly supports USF’s fundamental environmental credentials derived from its core

business as an investor and owner of utility scale solar energy assets. The Company’s policies, including

those pertaining to sustainability, are reviewed with the Board and monitored on an ongoing basis as

needed and formally on an annual basis.

USF’s Board has an Audit Committee whose function is to ensure that the Company maintains the highest

standards of integrity, financial reporting, internal control and risk management systems and corporate

governance. One of the main duties of the Audit Committee is reviewing the risks facing the Company and

monitoring the risk register. These include climate related risks. The Audit Committee is required to report

formally to the Board on its findings after each meeting on all matters within its duties and responsibilities.

2. Describe management’s

role in assessing and

managing climate-related

risks and opportunities.

Developing, implementing, managing and reporting on USF’s sustainability activities is undertaken by the

Investment Manager, which reports to the Board on an ad hoc and at least quarterly basis.

The Investment Manager monitors climate-related legal and regulatory developments in the US and

globally as well as noting the changing dynamics or weather patterns and local climates that may impact the

day-to-day production of USF’s solar projects. This data informs the investment and operating decisions of

the Investment Manager who reports to the Board at least quarterly on generation performance and any

critical changes. The Investment Manager is also informed from specialist opinions on a range of matters,

including environmental factors and irradiance forecasts obtained during acquisitiondue diligence.

Strategy Disclose the actual and potential impacts of climate-related risks and opportunities on the organisation’s

businesses, strategy, and financial planning where such information is material.

3. Describe the climate-

related risks and

opportunities the

organisation has identified

over the short, medium,

and long term.

The Company recognises that the key climate-related opportunity impacting its business is the positive

impact and demand for renewable energy. USF was established to meet this demand and recognises

that the pace of transition to clean energy in the US will impact the size of the Company’s investment

opportunity. Based on the current administration’s position on clean energy, USF expects demand to

continue to grow significantly over the short (1-2 years), medium (2-5 years) and long term (5-25+ years).

USF recognises there are climate change risks which could have an impact on the Company’s returns and

growth opportunities. These risks could be transition risks and physical risks. Transition risks relate to the

transition to a lower carbon economy, and can be grouped into market risks technological risks, political

and legal risks and reputational risks. These risks are discussed in more detail in Section 5 - Principal Risks

and Uncertainties. Physical risks relate to the impact of climate change on energy assets and operating

companies. These include short term extreme weather events (wildfires, flooding, severe storms, drought)

and longer-term impacts such as rising sea levels and global temperatures.

USF notes that the following physical risks (which are also discussed in the following Principal Risks and

Uncertainties Section) are related to climate change and may be viewed as climate-related risks either

directly or indirectly:

• Unfavourable weather conditions including climate change or events impacting irradiance over the

medium to long-term.

• Power Price Fluctuations: Power prices are impacted by changes in weather (extreme heat or cold,

large storm systems, etc. which may be the result of climate change) in the short, medium and long

terms, noting the Company’s PPA arrangements mitigate the short and medium-term impacts.

US SOLAR FUND PLC Annual Report and Financial Statements

Strategy Disclose the actual and potential impacts of climate-related risks and opportunities on the organisation’s

businesses, strategy, and financial planning where such information is material.

• Under-performance of equipment at solar power plants relative to acquisition assumptions: short

duration under-performance may result from the impact of physical risks including weather patterns,

forest fires and storms that result from climate change, such as higher temperatures at peak

generation times.

• Increasing grid outages and time of day pricing: in combination with increasing renewables generation

seeking grid access, climate-related risks can increase grid outages. This is a risk for new projects

and an opportunity for existing projects. USF evaluates this risk/opportunity by considering grid

curtailment and interconnection arrangements as part of acquisition diligence, partly contracting for

curtailment in PPA’s and evaluating storage opportunities.

See Principal Risks and Uncertainties Section for discussion of the impact of the risks and their mitigants.

4. Describe the impact of

climate-related risks

and opportunities

on the organisation’s

business, strategy, and

financialplanning.

The Company was established to take advantage of efforts to increase the share of renewable or clean

energy in the US. This is core to all business activities of the Company.

The Company manages the impact of climate-related risk on both the production of its assets and the

stability of its cash flows, primarily through geographic diversification and by securing long-term PPAs.

USF has a portfolio of 42 solar projects across four states in the US, using diversification to reduce the

portfolio’s exposure to any one extreme weather or environmental event (i.e. fires, heavy rainfall, extreme

heat, heavy snowfall).

The Company minimises the impacts of medium-term climate related risks including the generation

performance of solar assets, ongoing maintenance costs and forecast merchant power prices, on revenue

by acquiring operating assets that have long-term PPAs in place (with a minimum target PPA term of 10

years for each project or portfolio acquisition and a weighted average remaining PPA term of more than

14 years for the Company’s entire portfolio). Medium-term contracts are also entered into with O&M

providers to provide stability to maintenance costs.

More recently, climate related opportunities have been explored relating to the addition of storage

capability where battery pad-sites and interconnection and offtaker arrangements are favourable,

and extending asset useful life where key contractual and asset parameters are met. The Investment

Manager’s assumptions and valuations have been adopted following independent reviews, and a proposal

to install a battery at the Company’s MS2 site is well advanced and will be considered by the Board once it

is complete.

5. Describe the resilience of

the organisation’s strategy,

taking into consideration

different climate-related

scenarios, including a 2°C

or lowerscenario.

USF uses a sensitivity analysis to determine the impact of changes in key assumptions on the fair value

of the Company’s investments. Many of these key assumptions are impacted by climate-related risks,

particularly electricity production and electricity prices which may be impacted by major environmental

or weather events. Based on the analysis, the Directors consider the changes in inputs to be within a

reasonable expected range based on their understanding of market transactions and current industry and

insurer views on longer-term climate volatility.

High transitional risks, associated with a 1.5–2ºC increase in temperature, have been considered to date

on a stand-alone basis. They include downward changes in forecast power prices by 10% from current

levels, which would reduce the Company’s NAV by 6.5 cents per share across the portfolio. Downward

pressure on forecast power prices creates a logic-breach of reducing future investment in new projects

as they become un-economic, leading to reduced roll-out of new power infrastructure. A slower roll-out

creates a supply side risk for power which would have the effect of reducing the downward pressure on

forecast prices. The policy solution to these issues is gathering momentum in most US power markets.

A second transitional risk scenario contemplates an increase in discount rate applied to the Company’s

assets because of price inflation linked to climate risks and demand for goods and services required to

maintain operating plants, and rising interest rates. An increase in the weighted average discount rate by

50 basis points would reduce the Company’s NAV by 5.2 cents per share over the assets’ useful lives.

High physical risk scenarios, associated with a 3-4ºC increase in temperatures, included:

• Reduction in availability of assets due to severe weather events and flooding, wildfires linked to higher

temperatures. A reduction in availability from P50 forecasts to P90 forecasts for the remaining useful

lives would reduce NAV per share by 11.8 cents, assuming access to insurance was not available.

• Reduced operating life of assets resulting from climate-related risks. A three-year reduction in useful

operating lives would reduce NAV per share by 3.8 cents.

The Company’s climate-related risks and opportunities matrix is complex. USF will consider integrated

climate-related scenarios in future reporting.

US SOLAR FUND PLC Annual Report and Financial Statements

Risk Management Disclose how the organisation identifies, assesses, and manages climate-related risks.

6. Describe the organisation’s

processes for identifying

and assessing climate-

related risks.

USF’s Board and Investment Manager review and update the risk register three times a year, including

assessing climate risks as relevant based on legal and regulatory developments, industry reports and

research, and data gathered from its own portfolio of assets. USF released its first annual Sustainability

Report for 2021 in February 2022. The report is a valuable practice for the Board and Investment

Manager to engage with climate-related risks and opportunities, noting that USF was created to take

advantage of investment opportunities in the US arising from the decarbonisation of energy generation

and usage.

At the asset level, the Investment Manager engages with climate-related risks and opportunities as well as

the Company’s impact on the local environment across all aspects of its activities: from due diligence and

acquisition of assets to construction and operation of projects:

• Environmental site assessments are completed for all assets during due diligence including

certification that all projects comply with applicable local, state or federal law. Vegetation clearance is

maintained at or below county regulations and in accordance with insurance requirements.

• Physical climate-related risks and mitigating measures are considered during the diligence process and

routinely throughout operations, including flooding risks, irradiance levels, wildfire and wind stowage.

• Site specific measures implemented during operations as appropriate, including minimisation of

water usage and monitoring consumption; planting of local/indigenous grasses, plants or wildflowers;

implementation of sustainable drainage and flood control measures. Panel cleaning practices and

project budgets are adapted to optimise performance in relation to climate-related risks (i.e., snowfalls,

ash from fires).

• 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.

• Engineering, Procurement, Construction (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.

7. Describe the organisation’s

processes for managing

climate-related risks.

Climate-related risks identified through the acquisition process are managed by the Investment Manager

with oversight from the Investment Committee through bid pricing. The appropriateness of environmental

and climate change risks, along with mitigating actions, are considered by the Investment Committee

and as part of their review of the Investment Manager’s bid assumptions. The Investment Manager’s

asset management team is responsible for reviewing asset performance, operations and maintenance

and external asset management providers, to ensure project level environmental and climate risks are

being managed and mitigated at the project level. Further disclosure is included in the Principal Risks and

Uncertainties section below, including mitigants noted for:

• Unfavourable weather conditions including climate change or events.

• Power Price Fluctuations: Power prices are impacted by changes in weather (including extreme heat

or cold, or large storm systems and flooding, which may be the result of climate change).

• Under-performance of solar power plants relative to acquisition assumptions: Under-performance

may be the result of changes in weather patterns and forest fires that result from climate change.

8. Describe how processes

for identifying, assessing,

and managing climate-

related risks are integrated

into the organisation’s

overall riskmanagement.

The Investment Manager maintains an enterprise-wide risk register and updates are presented to the

Board three times a year for review and updating, including a comprehensive review annually. Climate-

related risks are included in this framework with risk assessed in terms of likelihood of occurrence, and

potential impact. The USF Board and the Investment Manager are acutely aware of the significance of

climate-related risks in terms of the performance of individual assets, and the extent to which correlated

events may have an overall effect on the performance of the portfolio.

Metrics and targets Disclose the metrics and targets used to assess and manage relevant climate-related risks and

opportunitieswhere such information is material.

9. Disclose the metrics used

by the organisation to

assess climate-related

risks and opportunities in

line with its strategy and

risk management process

The Company invests in and sells energy generated by its Solar Assets to energy offtakers, directly

contributing to renewable energy infrastructure and renewable power generation. The Company uses a

variety of metrics to monitor the contribution to mitigating climate change, including GWh of renewable

energy generation, tonnes of carbon dioxide emissions displaced and homes powered by clean energy.

The Company and Investment Manager considers several metrics that relate to climate related risks and

opportunities. At this stage, the metrics are used to manage a pool of climate-related risks, rather than

specific metrics for specific risks, including:

• Proportion of asset life and revenues with fixed price off-take agreements, which influences the extent

to which changes in merchant prices affects forecast cash flows and the portfolio valuation.

• Generation performance to expectations, where variances are examined for root causes, including

longitudinal climate-related impacts on potential asset availability.

• Regional diversification is a critical aspect of USF’s climate risk management with budget generation,

revenue and NAV spread across 42 projects and four states as follows:

State % of Budget Generation MWh % of Revenue % of NAV

and if appropriate,

Scope 3 greenhouse gas

(GHG) emissions, and the

relatedrisks.

The Greenhouse Gas (GHG) Protocol categorises greenhouse gas emissions into three categories or

scopes. Scope 1 covers the Company’s direct emissions from owned/controlled sources; Scope 2 covers

indirect emissions from the generation of purchased electricity, air travel, heating and cooling consumed

by the Company; and Scope 3 includes all other indirect emissions that occur in the Company’s value chain.

Operating solar power plants do not emit greenhouse gases or any gaseous by-product, so Scope 1 direct

emissions are nil.

USF measures its annual carbon footprint as laid out in SFDR Annex One included in the Sustainability

Report. Scope 1 and estimated Scope 2 emissions for 2021 based on Nature (2017) range of 3.5g to

12g CO

eq/KWh are disclosed below. The Company is developing its approach to measuring the GHG

footprint of its entire portfolio.

California 277.5 0 971.4 – 3,330.5

Total 908.3 0 3,179.1 to 10,899.9

Scope 3 emissions involves significant data collection to support baseline emissions calculations and

further work and expert advice is needed to develop the Company’s disclosures. The Company is looking

to engage an expert this year, with a view to commencing this project and developing a timetable to target

reporting on Scope 3 emissions in its 2023 Sustainability Report.

11. Describe the targets used

by the organisation to

manage climate-related

risks and opportunities

and performance

againsttargets.

As the Company’s core business is generating clean energy, the core performance target is the amount

(inGWh) of electricity generated from its portfolio of utility scale solar projects.

In addition, the following secondary performance targets are monitored to track the levels of CO

generated by the business, and the net CO

avoided by the renewable power generated by the portfolio:

• carbon footprint of the business is estimated at 58t per annum (refer Sustainability Report); and

• CO

emissions displaced

USF’s portfolio comprises 42 operational solar plants and the portfolio was responsible for displacing

more than an estimated 639,000 tonnes

of CO

emissions.

25 First year of electricity production once project becomes fully operational or since acquired.

26 Environmental figures use actual generation figures for 2021. US CO² emissions displacement is calculated using data from the US Environmental Protection

Agency’s “AVoid Emissions and geneRation Tool” (AVERT).

US SOLAR FUND PLC Annual Report and Financial Statements

SITE-SPECIFIC ESG INITIATIVES DURING OWNERSHIP

As assets are onboarded and in-construction assets become operational, site-specific KPIs are implemented based on a list of potential measures

for each asset. The US is vast and contains many different ecological environments. The measures used for each site depend on the local

environment as well as the size of the asset. As USF assets range from 2MW

to 200MW

different measures are appropriate for different size

assets. The list below includes actual measures that have been implemented and options that are being considered at various USF sites:

ENVIRONMENTAL

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

• Vegetation management at or below county regulations to minimise the impact of wildfires (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).

Governance considerations also 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.

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 register that is subject to a detailed

review 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:

• climate-related risks (refer to disclosures made in Section 4 and USF’s Sustainability Report);

• legal & regulatory risks;

• financial & market risks; and

• operational risks.

The principal risks for the period and their mitigants are summarised in the tables below.

LEGAL & REGULATORY RISKS

Risk

Impact on Company Mitigant

Changes in laws

or regulations

governing the

Company’s

operations or

the Investment

Manager’s

operations

Regulation changes may adversely affect the

business and performance of the Company.

The Company is sensitive to tax changes for

example, including but not limited to income tax,

Investment Tax Credits and tax restrictions on

renewables. An adverse change in tax legislation

may impact the Company’s overall returns.

The Company and Investment Manager monitor changes in

legislation for relevant jurisdictions to enable rapid and effective

response. This ensures that any upcoming changes in legislation are

proactively accounted for when evaluating potential investment

opportunities. The Company and Investment Manager also consult

with tax and regulatory experts as required.

US legislation remains supportive of an energy transition, with the

Infrastructure and Jobs Act

passed through Congress in November

2021, which included $65billion to upgrade transmission capabilities,

which will assist integration of renewable generation into US grids.

Political risk Political risks often translate to elevated political

uncertainties and have detrimental effects on

investment and currency markets. The separation

of the United Kingdom (UK) from the European

Union (EU) may impact the Company’s ability to

raise additional funds.

The outcome from US Congress decisions and

changes in US administration, and the impacts

on renewable energy credits, tax concessions

and support for the renewable generation sector

areuncertain.

As the Company’s assets are in the US, the Investment Manager does

not consider separation from the EU to cause significant risks to the

US renewables market. Noting the success of the Company’s equity

raise in April 2021, the impact on the Company’s ability to attract

capital was minimal.

The Company and Investment Manager monitor changes in

legislation for relevant jurisdictions to enable rapid and effective

response. The Company and Investment Manager also consult with

tax and legislation experts as required.

The policy objectives of the Biden administration regarding net zero

carbon emission energy generation has lowered the political risk

associated with investment in US renewable energy.

US SOLAR FUND PLC Annual Report and Financial Statements

FINANCIAL & MARKET RISKS

Risk

Impact on Company Mitigant

Long-term power

price fluctuations

PPA terms are generally shorter than the

expected useful life of Solar Assets so price

forecasts are used to estimate the value of cash

flows between PPA expiry and the end of the

asset’s useful life. Lower or higher wholesale

electricity price forecasts will reduce or increase

the revenue that the Solar Assets are expected

to generate after PPA expiry, thereby impacting

asset valuations.

The Company secures revenue by acquiring assets that have long-

term PPAs in place (with a minimum PPA term of 10 years for each

project or portfolio acquisition and a target weighted average PPA

term of approximately 15 years for the Company’s entire portfolio).

The Company continues to regularly monitor changes in expert

energy price forecasts and ensures that they are appropriately

factored into asset valuations. The Company averages forecast

price curves from two reputable providers over their most recent

two periods (i.e., four curves in total) to mitigate the impact on asset

values from any one forecaster changing views. Additionally, the

Company is evaluating energy storage as a means to reduce exposure

to power price and re-contracting risk.

Valuation of

assets

The due diligence process that the Investment

Manager undertakes in evaluating acquisitions

of Solar Assets may not reveal all facts that may

be relevant in connection with such investments,

including the impacts of climate related risks.

This could lead to valuation errors that affect

the returns achieved by the underlying assets or

results in inaccurate reporting to investors and

other stakeholders.

The Company appoints an independent reputable firm to undertake

valuations of its Solar Assets on at least an annual basis. Further, the

Company appoints reputable third parties with industry specific skills

to assist in the due diligence process including reviewing detailed

financial model inpu ts.

Access to capital

from tax equity

partners and debt

providers

The Company may not be able to source funding

from suitable tax equity partners and debt

providers which may limit the amount of capital

the Company is able to invest. Additionally,

the Company may be exposed to risks from its

contractual relationships in relation to tax equity

financing with any tax equity partner.

Debt and tax equity financing is in place for all projects in the

Company’s portfolio except for Granite (Acquisition Three), with

US Bancorp fully exiting the tax equity structure as expected

during the period. The Company has appointed a reputable and

experienced Investment Manager with strong existing banking and

tax equity relationships. These existing relationships, in addition to

new relationships, developed with experienced tax equity partners

allow for various avenues to appoint a partner best suited for the

project. The Company also continues to monitor compliance with tax

equity financing provisions. The Company successfully refinanced

its Acquisition Four (Heelstone Portfolio) debt facility, using existing

banking relationships of the Investment Manager, with proceeds from

the April 2021 share placement.

Unable to source

suitable Solar

Assets

The Company may not be able to source suitable

assets in future, which would result in Company

holding levels of cash which are higher than

optimal. This cash would likely generate much

lower levels of returns than the assets in the

Company, consequentially adversely affecting the

level of returns to shareholders and the market

value of the Company.

The Company has appointed an Investment Manager with a

dedicated team of experienced investment and renewable energy

professionals focused on sourcing, evaluating and transacting on new

investments for the Company, to deploy all available capital. As of

31December, the Investment Manager has a pipeline of 1,940MW

of high-quality assets, with an aggregate value of approximately

$2.2billion in cash equity value and a weighted-average PPA term of

17.7 years, including opportunities to expand USF’s existing projects

with battery storage. The IPO proceeds and 2021 capital raising

proceeds are largely invested (upon completion of MS2 Tranche2)

with $16 million remaining for working capital and other growth

opportunities. In addition, the Company has an undrawn $40 million

RCF to deploy in near term asset purchases.

US SOLAR FUND PLC Annual Report and Financial Statements

Risk

Impact on Company Mitigant

Interest rate risk The Company has debt facilities with both fixed

and floating interest rates. The Company is also

exposed to interest rate risk though holding

variable rate bank deposits. As such, changes in

interest rates may have a positive or negative

impact directly on the Company's net income

and, consequently, the profits of the Company.

Changes in interest rates may also affect the

discount rates used in the valuation of the assets.

Interest rate risk, along with increasing operating

costs, offset by higher long term merchant power

prices are areas that the broader market risk of

rising inflation impacts the Company (refer below).

The base interest rate for all amortising debt is fully hedged for

the term of the relevant loan, and for one or more subsequent

re-financings. The FTB Facility has a floating interest rate which is

not hedged but is currently undrawn. The interest rate risk on this

instrument and on bank deposits is not significant given the relatively

low balances and current low level of interest rates. The Company

does not bear interest rate risk on its loan to USF Holding Corp. as

the loan rate is fixed for the duration of the loan facility. Changes in

interest rate that affect the discount rates used in the valuation of the

assets will also tend to impact long-term electricity price forecasts

which provides a partial hedge. In the event of the Company investing

in new projects, the Company’s standard practice is to hedge the

floating rate risk on the actual and anticipated debt amortisation

profile at the time of investment.

Inflation risk Inflation in the Company’s context is likely to

result in higher:

• capital costs for new projects;

• operating and maintenance costs for existing

and new projects;

• revenues from higher spot and PPA

electricityprices;

• interest rates for servicing debt (refer above);

• market rates of return required for equity

invested in new projects; and

• discount rates for valuing equity in

existingprojects.

USF’s operating cash flows are relatively fixed, except for the period

of merchant generation beyond the term of existing PPAs. Higher

long-term interest rates, however, will result in higher discount rates

being applied to all cash flows for valuing USF’s assets and equity

investments. Adverse changes in valuations are likely to apply to all

asset classes (not just solar generation) which have relatively fixed

cash flows, so USF’s cash flows, which are relatively fixed in the

medium-term due to existing PPAs and interest rate hedging, are

likely to be impacted. A potential mitigant is a reduction is the asset-

specific risk premium applied for each USF asset as well as potentially

higher forecast electricity prices after the term of the existing PPAs.

Higher capital costs, operating costs and required returns of capital

are likely to present additional challenges to new projects. When USF

is investing in new projects, then inflation may make it more difficult

for new projects to meet required returns.

USF has existing fixed term O&M contracts in place, but these are

generally of much shorter term (up to 5 years) than project PPAs and

interest rate hedging (typically over 10 years). Higher costs may be

expected from replacement contracts, which along with higher prices

for replacement parts and equipment, is likely to result in higher

overall operating costs.

USF’s existing long-term PPAs means that the Company’s assets

will not be able to benefit from higher PPA prices until the existing

PPAs expire. The net impact from inflation on the current portfolio is

uncertain as it depends on changes to post-PPA revenue, O&M costs,

debt service costs and valuation effects from higher discount rates.

OPERATIONAL RISKS

Risk

Impact on Company Mitigant

Operational

fraud

The Company is potentially exposed to financial

losses from fraudulent activities related to receipts

from counterparties or wholesale markets,

or payments made to construction entities,

maintenance providers and capital investors.

The Investment Management Agreement (IMA) provides USF

with certain protections through passing certain responsibilities to

the Investment Manager. The Investment Manager maintains and

adheres to policies and processes to mitigate the risk of fraud. The

E&P Financial Group Limited, of which the Investment Manager is a

member, holds insurance which covers fraudulent incidents.

US SOLAR FUND PLC Annual Report and Financial Statements

Risk

Impact on Company Mitigant

Default of

developer or

EPCcontractor

The Company may experience a financial loss

(realised or unrealised) from a developer or EPC

counterparty failing to perform their contractual

obligations including warranty obligations which

continue after construction is completed.

The Company has a fully operational portfolio, with no Solar Assets

currently under construction. Where the Company undertakes

construction activity in the future, it appoints experienced and

reputable contractors with strong track records and through existing

relationships with the Investment Manager. The Company will

periodically review the credit ratings and other available financial

indicators of counterparties before contracting and adjust risk

premiums accordingly. Contractual protections in EPC contracts

(milestone-based payments, performance security, liens over assets

purchased and installed by the EPC contractor), means the potential

impact of EPC contractor default during construction is largely

limited to the time and cost of replacing the contractor rather than

any persistent loss.

Unfavourable

weather

conditions

including climate

change or events

The Company may be exposed to a lower than

expected volume of revenue generation produced

by the Solar Assets. Additionally, the Solar Assets

may face damages due to extreme weather

conditions arising from climate change.

The Company and Investment Manager conduct sensitivity analysis

using a range of power generation forecasts when evaluating

acquisitions however isolated or localised conditions such as storms,

heavy snowfall, or smoke and dust events may cause production

shortfalls outside the range of power generation forecasts. Investing

in geographically diverse projects mitigates the impact of localised,

unfavourable weather conditions.

Under-

performance

of solar power

plants relative

to acquisition

assumptions

The underperformance of Solar Assets may lead

to reductions in energy generated and thereby

a reduction in revenue that the asset would be

expected to produce.

The Company uses third-party independent engineers to review

the assets and provide independent reports on performance before

acquisition, to ensure that reasonable generation assumptions

are utilised. The Company and Investment Manager also conduct

sensitivity analyses on power generation when evaluating the

acquisition target. The Company and the Investment Manager also

seek to engage with reputable O&M and EPC contractors and include

market-standard contractual protections in the relevant contracts.

Pandemics

including

COVID-19

Global health concerns often translate to elevated

uncertainties in financial markets and have

detrimental effects on the global economy. The

COVID-19 outbreak may impact the Company’s

supply chain and service providers (such as

higher O&M costs, longer response times, and

higher insurance costs) and also its ability to raise

additional funds.

The Investment Manager has established systems and procedures

that allow remote monitoring of the solar power assets and remote

work by staff. These systems have operated throughout COVID-19,

included extended periods of lock-down restrictions. The Investment

Manager manages costs by using fixed-time and fixed-cost contracts

for construction, working closely with EPC contractors during the

construction of assets, and with O&M contractors and other key

suppliers once assets become operational.

Noting the success of the Company’s equity raise in April 2021

during the pandemic, the impact on the Company’s ability to attract

capital was minimal.

Counterparty

credit risk

There is the potential for losses to be incurred

due to defaults by PPA counterparties, EPC

contractors, derivative counterparties, and

deposit taking institutions.

There have been no material changes to the creditworthiness of any

of the USF counterparties as a result of COVID-19, and the Company

and the Investment Manager diversifies credit risk across multiple

investment-grade counterparties. No financial transactions are

permitted with counterparties with a credit rating of less than BBB-

from Standard & Poor’s or Baa3 from Moody’s unless specifically

approved by the Board. The Investment Manager will continue

to monitor credit market conditions, including as they apply to

PPAcounterparties.

US SOLAR FUND PLC Annual Report and Financial Statements

Risk

Impact on Company Mitigant

War/Major

conflict risk

War or major conflicts have the potential to

impact the Company’s generating capability

directly (through uninsured damage or

destruction of operating assets or grid

infrastructure) and indirectly, through the fair

value impact on the portfolio from adverse

movements in macro-economic factors or

impacts on the Company’s PPA offtakers and

keysuppliers.

The current Russia/Ukraine conflict is in its early stages, and

therefore it is too early to determine the potential impacts on

the Company. While North Atlantic Treaty Organisation (NATO)

countries are presenting a unified response, with economic sanctions

against Russia and military support for the Ukraine, the overall

impact on the Company’s US operating portfolio of Solar Assets

and its sources of capital from the UK and EU are not clear. While

direct impacts on the operating portfolio are not considered likely,

the Board and Investment Manager continue to monitor the conflict

closely and consider appropriate mitigating actions.

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 principal risks facing the Company set out above over a five-year period, which it considers appropriate given the

long-term nature of the Company’s investments and its long-term planning horizon. 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 30 to 34 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 geographical 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 short term 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, including the potential impacts of climate related risks, over a longer period given the inherent uncertainty involved.

It is important to note that the risks associated with investments within the solar infrastructure sector, including rising inflation and climate

related risks resulting in unfavourable weather conditions for extended periods, 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 relies on Shareholders for continued access to capital to support further growth of the Company. The Board is accountable to the

Shareholders for running of the business, making key strategic decisions and all key service provider appointments. The Board is non-executive

and independent and delegates certain key activities, including the day-to-day investment management and asset management to the Investment

Manager, and administration and company secretarial functions to the Administrator.

US SOLAR FUND PLC Annual Report and Financial Statements

The Board works closely with the Investment Manager, Company Secretary and its Corporate Brokers, to ensure it is aware of Shareholders’

needs or concerns, and the Investment Manager liaises with Shareholders through specified reporting of Company performance, strategy and

outlook at set dates in the calendar, as well as ad hoc reporting of major announcements, and sessions organised by the Company’s brokers.

In addition, Shareholders have the opportunity to meet the Board at the Annual General Meeting (AGM), though during the pandemic these have

been held virtually. The Board also endeavours 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 Company refinanced the Heelstone project debt facilities and

extended the tenor and increased its corporate RCF limit during the period.

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, being renewable power generation, and to ensuring that as a business

we meet the high standards of conduct that we set ourselves. The Company has a set of corporate service providers, including the Investment

Manager, Administrator and External Auditor, who provide services to ensure the smooth operation of the Company, and periodic independent

review of financial statements.

The Board meets once a year to discuss and 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. The External Auditor typically attends two of the three Audit Committee

meetings scheduled throughout the year, to present their reports on the interim review and annual audit.

The Company's underlying project companies also have project suppliers, including O&M and external asset managers who were incumbent at

acquisition. Where assets are acquired in construction, the EPC contractors and Original Equipment Manufacturers (OEM) who supply panels,

inverters, and other key components are key suppliers. While there are currently no projects under construction, the Investment Manager’s asset

management team maintains relationships with all project suppliers, including landowners for leased sites.

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.

The Association of Investment Companies (AIC) shapes the influence of the growing listed investment company segment in the London market,

and USF seeks to apply AIC guidelines where relevant to its operations, including the 2019 AIC Code of Corporate Governance.

PPA OFFTAKERS

The Offtakers for the Company’s projects provide the main source of operating cash inflows to the Company, and the Company requires Offtake

agreements be entered into with credit-worthy counterparties as part of its investment mandate. 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. Complaint handling procedures are in place at all sites, with no significant complaints received during the year, and one minor

complaint regarding screening and vegetation buffers at the Chiloquin site in the process of being resolved at year end.

GOING CONCERN

The Board has reviewed a set of financial projections of the cash flow and distribution profile of the Company prepared by the Investment

Manager. The Board has assessed the prospects of the group by reviewing its short-term cash flow forecast which covers a two year period,

and completed a detailed assessment to support the going concern conclusion for the 12 months following the signing of the Annual Report.

After assessing these risks, and reviewing the Company’s liquidity position, together with forecasts of the Company’s future performance under

various scenarios, the Board has a reasonable expectation that the Company will continue to meet its obligations as they fall due for at least the

next 12 months. As such the Board concluded that it is appropriate to adopt the going concern basis of preparation in preparing these financial

statements. For further details on going concern please see Note 2 of the Financial Statements.

POLITICAL CONTRIBUTIONS

The Company made no political contributions during the period.

POST-BALANCE SHEET EVENTS

On 10 February 2022, USF announced it would exercise the Company’s option on a second 25% tranche of the 200MW

8. Directors’ Responsibility

Statement

The Directors are responsible for preparing the Annual Report and financial statements in accordance with applicable law and regulations.

As a Company listed on the London Stock Exchange, US Solar Fund plc is subject to the FCA’s Listing Rules and Disclosure and Transparency

Rules, as well as to all applicable laws and regulations in England and Wales where it is registered.

The financial statements have been prepared in accordance with UK-adopted international accounting standards. Under the UK Companies Act

2006, the Directors must not approve the financial statements unless they are satisfied they give a true and fair view of the state of affairs of the

Company and of the profit or loss for the period. In preparing these financial statements, the Directors should:

• select suitable accounting policies and then apply them consistently;

• make judgements and estimates that are reasonable;

• specify which generally accepted accounting principles have been adopted in their preparation; and

• prepare the financial statements on the going concern basis, unless it is inappropriate to presume that the Company will continue in business.

The Directors are responsible for keeping proper accounting records which are sufficient to show and explain the Company’s transactions and

are to disclose with reasonable accuracy at any time the financial position of the Company and enable them to ensure that the financial statements

comply with the requirements of the Companies Act 2006. They are also responsible for safeguarding the assets of the Company and hence for

taking reasonable steps for the prevention and detection of fraud and other irregularities.

The Directors are also responsible for preparing the Annual Report and financial statements and the Directors confirm that they consider that,

taken as a whole, the Annual Report and financial statements are fair, balanced and understandable and provide the information necessary for

shareholders to assess the Company’s performance, business model and strategy. In accordance with the FCA’s Disclosure and Transparency

Rules, the Directors confirm to the best of their knowledge that:

a) the financial statements, prepared in accordance with applicable accounting standards, give a true and fair view of the assets, liabilities,

financial position and profit or loss of the Company taken as a whole;

b) the Annual Report and accounts include a fair view of important events that have occurred during the financial period; and

c) the Annual Report and accounts include the related parties’ transactions that have taken place in the financial period and that have materially

affected the financial position or the performance of the enterprise during that period.

9. Corporate Governance

Report

Turkey Hill 13.2MW

Davis Lane 7MW

9. Corporate Governance Report

The Board of US Solar Fund Plc has considered the Principles and Provisions of the Association of Investment Companies (the AIC) Code of

Corporate Governance (AIC Code). The AIC Code addresses the Principles and Provisions set out in the UK Corporate Governance Code (the

UK Code), as well as setting out additional Provisions on issues that are of specific relevance to the Company.

The Board considers that reporting against the Principles and Provisions of the AIC Code, which has been endorsed by the Financial Reporting

Council, provides more relevant information to shareholders.

The Company has complied with the Principles and Provisions of the AIC Code. The AIC Code is available on the AIC website (https://www.

theaic.co.uk/aic-code-of-corporate-governance). The AIC Code includes an explanation of how the AIC Code adapts the Principles and

Provisions set out in the UK Code to make them relevant for investment companies. The Company is a member of the AIC.

THE BOARD

The Board consists of four non-executive directors all of whom are deemed to be independent of the Investment Manager.

The Company has not appointed a senior independent director as all directors are non-executive directors.

Biographical details of all Board members (including significant other commitments of the Chair) are shown on page 40.

In accordance with the AIC Code, all the Directors will retire at the forthcoming AGM and, being eligible, will offer themselves for re-election.

Full Board meetings take place quarterly and the Board meets or communicates more regularly to address specific issues. The Board has a formal

schedule of matters specifically reserved for its decision which includes but is not limited to: considering recommendations from the Investment

Manager ensuring the Company is delivering on its strategy and monitoring performance against the Company’s strategic objectives.

The Board has also established procedures whereby Directors wishing to do so in the furtherance of their duties may take independent

professional advice at the Company’s expense.

All Directors have access to the advice and services of the Company Secretary. The Company Secretary provides the Board with full information

on the Company’s assets and liabilities and other relevant information requested by the Chair, in advance of each Board meeting.

BOARD COMMITTEES

The Board has delegated a number of areas of responsibility to its three committees; the Audit Committee, the Remuneration and Nomination

Committee and the Management Engagement Committee. Each committee has defined terms of reference and duties.

AUDIT COMMITTEE

The Audit Committee consists of the full Board and is chaired by Jamie Richards. Jamie is a chartered accountant and has recent and relevant

financial experience. The Audit Committee normally meets at least three times a year to consider, amongst other things, the following:

• the financial reporting process of the Company including the accounting standards, estimates and judgements made by the Company, taking

into account the views of the Auditor;

• the internal controls and risk management systems;

• oversight of the external audit process including scope, independence and objectivity of the external auditors; and

• the risks facing the Company including ESG risks.

A full list of matters reserved for the Audit Committee can be found in the Audit Committee Report on pages 61 to 64.

The Audit Committee has performed an assessment of the audit process and the Auditor’s Report, details of which can be found in the Audit

Committee Report on pages 61 to 64. The Directors have decided to recommend the re-appointment of Deloitte LLP as auditor and a resolution

concerning this will be proposed at the Annual General Meeting.

REMUNERATION AND NOMINATION COMMITTEE

The Remuneration and Nomination Committee is comprised of the whole Board and chaired by Rachael Nutter, which is considered appropriate

given the size of the Board and the fact that the Company has no executive directors or employees.

US SOLAR FUND PLC Annual Report and Financial Statements

In accordance with the Committee’s terms of reference, no director is involved in any decisions with respect to their own remuneration.

The Company’s Remuneration policy was last approved by Shareholders at the 2020 AGM and will therefore be put to a vote at the 2023 AGM as

part of the regulatory three yearly approval process. Full details on this Policy can be found in the Remuneration Report on pages 65 to 68.

This committee meets as required to consider, amongst other things, the following:

• in conjunction with the chair, setting the directors’ remuneration levels;

• considering the need to appoint external remuneration consultants;

• the process for appointments;

• ensuring plans are in place for orderly succession to the Board; and

• the development of a diverse pipeline for succession.

In reviewing Board composition, the Committee will consider the benefits of all aspects of diversity including, but not limited to, differences in

knowledge and understanding of relevant diverse geographies, peoples and their backgrounds including race or ethnic origin, sexual orientation,

gender, age, disability or religion, in order to maintain an appropriate range and balance of skills, experience and background on the Board.

ACTIVITIES DURING THE YEAR

REVIEW OF BOARD REMUNERATION

During the year the Remuneration and Nomination Committee carried out a review of the non-executive Directors’ fees. This review was

supported by a peer group fee analysis report prepared by the Company Secretary. It was noted that the Director fees had not increased since

the IPO in 2019 and since then there has been significant ongoing time commitments of the Directors which included a successful capital raise.

The Committee also considered the need to maintain remuneration in line with the market as well as inflation, and agreed it was appropriate for

the Board’s fees to be increased by 5% from 1 January 2022. The full details for the directors fees paid during 2021 and to be paid in 2022 are set

out on page 67.

BOARD EVALUATION

The Board undertook a formal internal annual evaluation of its own performance by way of a questionnaire completed by each Director. The

Chair of the Committee and the Chair of the Board then discussed the results with the rest of the Board and took appropriate action to address

any issues arising from the process. It was concluded that the Board performed well and worked effectively together, under the leadership of the

Company’s Chair, to achieve the objectives and that each Director continues to contribute effectively. No weaknesses in the Board’s capabilities

were identified.

TENURE OF CHAIR AND SUCCESION POLICY

The Board has adopted a policy on Chair Tenure and Succession Planning. In line with this policy, the Chair should be in place for a maximum of

nine years. As stated in the 2019 AIC Code of Corporate Governance the chairs of investment companies differ to chairs of other companies

which means that the maximum tenure of nine years does not necessarily apply. However, in order to address the need for regular refreshment

and diversity, the Board believes that a tenure of nine years is appropriate.

The Board’s policy for succession planning is that there should be forward-looking and detailed succession and refreshment plans when proposing

re-election of long-serving members. Any member of the Board who has served for nine years will be subject to a particularly rigorous review and

evaluation process to determine whether they remain independent and should continue in their position. Each Board member is subject to annual

re-election at each AGM.

MANAGEMENT ENGAGEMENT COMMITTEE

The Management Engagement Committee is comprised of the entire Board and is chaired by Rachael Nutter. This Committee meets as required

to consider, amongst other things, the following:

• the appointment and terms of engagement of the Company’s service providers including the Investment Manager and AIFM; and

• the performance of all key service providers.

The auditor is not included in this review as its appointment and evaluation falls under the remit of the Audit Committee.

The Committee met once during the year to review the service levels and the fees for the key service providers to the Company. The Committee

has recommended retention of the existing service providers to the Company, having challenged fee and service levels as appropriate. Key

services providers will continue to be reviewed, at least, annually.

US SOLAR FUND PLC Annual Report and Financial Statements

The Committee also carried out a robust assessment of the Investment Manager and AIFM. The Committee concluded that the Investment

Manager had complied with the terms of the Investment Management Agreement and that the Investment Manager and the AIFM had met their

obligations to the Company during the period under review. The Committee also reviewed the fees paid to the Investment Manager and the AIFM

and concluded that these were at a similar level to the fees paid by the Company’s peers.

The Committee remains firmly of the view that the Investment Manager and AIFM demonstrate the skills and commitment to perform their roles,

and recommended their continued appointment to the Board. Full details of the Committee’s review of the Investment Manager and AIFM’s

overall performance is set out on pages 70 to 71.

Committeemeeting.

The Board meets formally on a quarterly basis and attendance is shown in the table above. During the period there were an additional 8 ad hoc

meetings, these are generally called to approve specific announcements or transactions and frequently involve a quorate sub-committee of the

Board, appointed as necessary.

Representatives of JTC (UK) Limited, as Administrator and Company Secretary, attend all scheduled meetings as Secretary to the Board. In

addition, representatives of the Investment Manager, the external auditor and other advisers, are invited to attend as required.

THE BOARD AGENDA

At our quarterly meetings, the Board follows a formal agenda. This agenda generally includes:

• the Investment Manager’s Report for the period, including strategic performance and acquisitions, a review of the performance of the

investments and market conditions;

• financial results against budget and cash flow forecasts, including dividends declared and forecast;

• reports and updates on shareholder and investor communications;

• the corporate governance and secretary’s report, with a review of policies and procedures, a compliance report and an update on legislative/

regulatory obligations as appropriate; and

• recommendations and updates from Board committees as appropriate.

KEY ACTIVITIES OF THE BOARD DURING 2021

The primary focus at regular Board meetings has been on delivering the strategy and monitoring performance against the Company’s strategic

objectives. The Board has also been monitoring all aspects of the Company’s business in light of COVID-19. This included:

• considering capital structure;

• discussing asset acquisitions and pipelines;

• reviewing conflicts of interest register and significant shareholdings; and

• reviewing the risk register.

US SOLAR FUND PLC Annual Report and Financial Statements

RELATIONS WITH SHAREHOLDERS

The Company communicates with Shareholders and solicits their views where it considers it is appropriate to do so. Shareholders are welcome to

attend the Annual General Meeting where they have the opportunity to ask questions of the Directors. The Board is also happy to respond to any

written queries made by Shareholders during the course of the period, or to meet with major Shareholders if so requested.

During the period the Chair has communicated with Shareholders on several occasions and further details can be found on page 52.

In relation to the conduct of the Company’s AGM, voting on all resolutions will be conducted by way of poll rather than a show of hands. This is

considered a more transparent method of voting as member votes are counted according to the number of shares held. As soon as practicable

following the meeting the results of the voting and number of proxy votes cast for and against and the number of votes actively withheld in

respect of each of the resolutions will be announced via a regulatory information service and also placed on the Company’s website.

The terms of reference of the Committees and the conditions of appointment of non-executive directors are available to Shareholders on request

and are also available on the Company’s website.

INTERNAL CONTROL

Although the Board is ultimately responsible for safeguarding the assets of the Company, the Board has delegated, through written agreements,

the day-to-day operation of the Company (including the Financial Reporting Process) to the following advisers:

Investment Manager New Energy Solar Manager Pty Limited

Administrator JTC (UK) Limited

The Audit Committee keeps under review the internal financial controls and internal control and risk management, ensuring that the procedures

to be followed by the advisers and themselves are in place.

The Board then reviews the effectiveness of the internal controls system, based on the report from the Audit Committee, on an annual basis to

ensure that the controls remain relevant and were in operation throughout the year.

The Board conducted its annual review of the Financial Position and Prospectus Procedures (FPPP) Board memorandum which was prepared by

the Investment Manager and Administrator and approved minor amendments. This sets out the procedures operating to identify the information

needed to monitor the business and manage risk so as to make proper judgements on its financial position and prospects. In addition, it sets out

the procedures to identify, assess and document the risk factors likely to impact on the Company’s financial position, prospects and any changes

and on the preparation and communication to the Directors of related information.

As part of its regular risk assessment procedures, the Board takes account of the significance of environmental, social and governance matters to

the business of the Company. The Board has identified and assessed the significant ESG risks to the Company’s short and long-term value, as well

as the opportunities to enhance value that may arise from an appropriate response. Further information on the Company’s approach to ESG can

be found on pages 21 to 27.

ANTI-BRIBERY POLICY

The Company operates an anti-bribery policy to ensure that it meets its responsibilities arising from the Bribery Act 2010.

making. The Board should keep engagement mechanisms under review so that they

remain effective.

Section 6: Division of Responsibilities (continued)

Principles (continued)

G. The Board should consist of an appropriate combination of Directors (and, in particular,

independent non-executive Directors) such that no one individual or small group of

individuals dominates the Board’s decision making.

The Board has a good mix of skills and works

effectively together, under the leadership of the

Company’s Chair, to achieve the objectives of the

Company. The Board comprises of four non-

executive directors all of whom are independent

from the Investment Manager, this helps to

ensure that appropriate challenge is made at

Board meetings as and when required.

H. Non-executive Directors should have sufficient time to meet their Board

responsibilities. They should provide constructive challenge, strategic guidance, offer

specialist advice and hold third party service providers to account.

The Board as part of its annual evaluation

analyses the time required to meet their Board

responsibilities and confirm that they have

sufficient time to meet them.

I. The Board, supported by the Company Secretary, should ensure that it has the

policies,processes, information, time and resources it needs in order to function

effectively andefficiently.

The Board, supported by the Company Secretary,

keeps under regular review the policies, processes,

information, time and resources it needs in order

to function effectively and efficiently. There

are regular review meetings between the Chair,

Audit Chair, Investment Manager and Company

Secretary to ensure effective and efficient

functioning of the Board.

Provisions – Director Responsibilities

8. The responsibilities of the chair, senior independent director, Board and committees

should be clear, set out in writing, agreed by the Board and made publicly available.

The annual report should set out the number of meetings of the Board and its

committees, and the individual attendance by directors.

These are set out in the Directors’ Report on

pages 41 to 43. The Annual Report also contains

a Committee Report for each Committee. These

can be found on pages 61 to 71.

The Board has not appointed a SID.

9. When making new appointments, the Board should take into account other demands

on directors’ time. Prior to appointment, significant commitments should be disclosed

with an indication of the time involved. Additional external appointments should not

be undertaken without prior approval of the Board, with the reasons for permitting

significant appointments explained in the annual report.

There were no new director appointments during

the year.

Provisions – Board and Director Independence

10. At least half the Board, excluding the chair, should be non-executive directors whom the

Board considers to be independent. The majority of the Board should be independent

of the manager. There should be a clear division of responsibilities between the Board

and the manager.

All the Directors are independent from the

Investment Manager.

11. The chair should be independent on appointment when assessed against the

circumstances set out in Provision 13.

The Chair, Gill Nott, was independent on

appointment and remains independent.

12. On appointment, and throughout the chair’s tenure, the chair should have no

relationships that may create a conflict of interest between the chair’s interest and

those of shareholders, including:

• being an employee of the manager or an ex-employee who has left the

employmentof the manager within the last five years;

• being a professional adviser who has provided services to the manager or the

Boardwithin the last three years; or

• serving on any other Boards of an investment Company managed by the

samemanager.

The Chair, on appointment and throughout her

tenure, continues to have no relationships that

may create a conflict of interest between her

interest and those of shareholders. The Chair

is and has always been independent of the

Investment Manager, in the capacity of employee,

professional adviser or serving on other Boards

managed by the same Investment Manager.

Section 6: Division of Responsibilities (continued)

Provisions – Board and Director Independence (continued)

13. The Board should identify in the annual report each non-executive director it considers

to be independent. Circumstances which are likely to impair, or could appear to impair,

a non-executive director’s independence include, but are not limited to, whether

adirector:

• has, or has had within the last three years, a material business relationship with

the Company or the manager, either directly or as a partner, shareholder, director

or senior employee of a body that has such a relationship with the Company or

themanager;

• has received or receives additional remuneration from the Company apart from a

directors’ fee;

• has close family ties with any of the Company’s advisers, directors or the manager;

• holds cross-directorships or has significant links with other directors through

involvement in other companies or bodies. Directors who sit on the Boards of more

however, they will not be regarded as independent for the purposes of fulfilling the

requirement that there must be an independent majority;

• represents a significant shareholder; or

• has served on the Board for more than nine years from the date of their

firstappointment.

Where any of these or other relevant circumstances apply, and the Board nonetheless

beprovided.

The Board comprises of four non-executive

directors all of whom are independent of the

Investment Manager.

14. The Board should appoint one of the independent non-executive Directors to be the

senior independent Director to provide a sounding Board for the Chair and serve as an

intermediary for the other Directors and shareholders. Led by the senior independent

Director, the non-executive Directors should meet without the Chair present at least

annually to appraise the Chair’s performance, and on other occasions as necessary.

Due to the size of the Board a senior independent

Director has not been appointed.

The Chair and Investment Manager maintain

appropriate communication with Shareholders. If

required, the other non-executive Directors are

available to Shareholders.

As the Board is small, any issues are discussed

and dealt with by the Board as a whole.

In the circumstance that there would be any

issues with the Chair, these would be dealt with

by the remaining non-executive Directors.

Provisions – Board Meetings

15. The primary focus at regular Board meetings should be a review of investment

performance and associated matters such as gearing, asset allocation, attribution

analysis, marketing/investor relations, peer group information and industry issues.

Board of Directors.

Where appropriate, the Investment Manager

supports the Board in discharging its

stewardshipobligations.

17. Non-executive Directors should review at least annually the contractual relationships

with, and scrutinise and hold to account the performance of, the Investment Manager.

Either the whole Board or a management engagement committee consisting solely of

Directors independent of the Investment Manager (or executives) should perform this

review at least annually with its decisions and rationale described in the annual report.

If the whole Board carries out this review, it should explain in the annual report why it

has done so rather than a separate management engagement committee.

The Company Chair may be a member of, and may Chair, the management engagement

committee, provided that they are independent of the Investment Manager.

The Management Engagement Committee

carried out a performance review of the

Investment Manager during the period.

knowledge. Consideration should be given to the length of service of the Board as a

whole and membership regularly refreshed.

Details of the Board’s skills, experience and

knowledge are set out on page 40 of this report.

The Board has a succession planning policy which

demonstrate whether each Director continues to contribute effectively.

Details of the Annual Evaluation can be found on

page 49 of this report.

Provisions

22. The Board should establish a nomination committee to lead the process for

appointments, ensure plans are in place for orderly succession to the Board and

oversee the development of a diverse pipeline for succession. A majority of members

of the committee should be independent non-executive Directors. If the Board has

decided that the entire Board should fulfil the role of the nomination committee, it will

need to explain why it has done so in the annual report. The Chair of the Board should

not Chair the committee when it is dealing with the appointment of their successor.

A combined Remuneration and Nomination

Committee was formed on 16 May 2019. Due

to the size of the Board and the nature of the

Company’s business, the entire Board fulfils

the role of the Remuneration and Nomination

Committee, with Rachael Nutter as Chair.

23. All Directors should be subject to annual re-election. The Board should set out in

the papers accompanying the resolutions to elect each Director the specific reasons

why their contribution is, and continues to be, important to the Company’s long-term

sustainable success.

In accordance with the AIC Code the Directors

are subject to re-election at each AGM.

24. Each Board should determine and disclose a policy on the tenure of the Chair. A clear

rationale for the expected tenure should be provided, and the policy should explain how

this is consistent with the need for regular refreshment and diversity.

The Company’s policy is that the Chair should not

hold office for more than nine years.

25. Open advertising and/or an external search consultancy should generally be used

for the appointment of the Chair and non-executive Directors. If an external search

consultancy is engaged it should be identified in the annual report alongside a

statement about any other connection it has with the Company or individual Directors.

There were no Board appointments made during

the period.

26. There should be a formal and rigorous annual evaluation of the performance of the

Board, its committees, the Chair and individual Directors. The Chair should consider

having a regular externally facilitated Board evaluation. In FTSE 350 companies this

should happen at least every three years. The external evaluator should be identified

in the annual report and a statement made about any other connection it has with the

Company or individual Directors.

The Remuneration and Nomination Committee

reviewed the results of the Annual Evaluation

of the Directors undertaken in 2021. It was

concluded that the Board members work

effectively together to achieve the objectives

and that each Director continues to contribute

effectively. Please refer to the Management

Engagement Committee’s Report on pages

69to71.

27. The Chair should act on the results of the evaluation by recognising the strengths and

addressing any weaknesses of the Board. Each Director should engage with the process

and take appropriate action when development needs have been identified.

The results of the evaluation were good,

no weaknesses in the Board capabilities

wereidentified.

The Audit Committee (the Committee) is chaired by Jamie Richards and comprises all of the independent Directors set out on page 40.

TheCommittee operates within clearly defined terms of reference and includes all matters indicated by Rule 7.1 of the UK FCA’s DTRs and the

AIC Code. The terms of reference were reviewed during the year under review and were updated to enhance the Committee’s scope to consider

key risks facing the Company. The Board is satisfied that the Committee is properly constituted with one member of the Committee who is a

chartered accountant with recent and relevant financial experience.

The Committee meets three times a year, and at such other times as the Committee shall require. Any Director who is not a member of the

Committee, the Administrator and representatives of the Investment Manager may be invited to attend meetings as and when deemedappropriate.

ROLE AND RESPONSIBILITIES OF THE AUDIT COMMITTEE

The function of the Committee is to ensure that the Company maintains the highest standards of integrity, financial reporting, internal and risk

management systems and corporate governance. The main duties of the Audit Committee are:

• monitoring the integrity of the financial statements of the Company and any formal announcements relating to the Company’s financial

performance and reviewing significant financial reporting judgements contained in them;

• review and challenge of the critical estimates and key judgements within the financial statements such as the assumptions supporting

the valuation of the Company’s investments, including discount rates, asset useful lives and forecast merchant power prices, which are

determined by the Investment Manager and independent valuer;

• reporting to the Board on the appropriateness of the Board’s accounting policies and practices including critical judgement areas;

• reviewing the valuation of the Company’s investments prepared by the Investment Manager, and making a recommendation to the Board on

the valuation of the Company’s investments;

• meeting regularly with the Auditor to review their proposed audit plan and the subsequent audit report and assess the effectiveness of the

audit process and the levels of fees paid in respect of both audit and non-audit work;

• making recommendations to the Board in relation to the appointment, re-appointment or removal of the Auditor and approving their

remuneration and the terms of their engagement;

• monitoring and reviewing annually the Auditor’s independence, objectivity, expertise, resources, qualification and non-audit work;

• reviewing the effectiveness of the accounting and internal control systems of the Company and considering annually whether there is a need

for the Company to have its own internal audit function;

• reviewing and considering the UK Code, the AIC Code, the FRC Guidance on Audit Committees and the Company’s institutional investors’

commitment to the UK Stewardship code; and

• reviewing the risks facing the Company and monitoring the risk matrix.

The Audit Committee is required to report formally to the Board on its findings after each meeting on all matters within its duties andresponsibilities.

FINANCIAL REPORTING

The primary role of the Committee in relation to financial reporting is to review with the Investment Manager, the Administrator and the Auditor

the appropriateness of the half-year report and Annual Report and financial statements, concentrating on, amongst other matters:

• the quality and acceptability of accounting policies and practices;

• the clarity of the disclosures and compliance with financial reporting standards and relevant financial and governance reporting requirements;

• amendments to legislation and corporate governance reporting requirements and accounting treatment of new transactions in the year;

• the impact of new and amended accounting standards on the Company’s financial statements;

US SOLAR FUND PLC Annual Report and Financial Statements

MEETINGS

During the year covered by this report, the Committee met formally on three occasions. The Committee considered and discussed the

followingmatters:

• consideration and agreement of the terms of reference of the Audit Committee for approval by the Board;

• review of the Company’s risk register;

• review of the internal controls of the Investment Manager and Administrator;

• review and approval of the audit plan of the Auditor and timetable for the interim and annual financial statements; and

• detailed review of the interim financial statements and Annual Report including active consideration of the judgements associated with the

investment held at fair value and discussions with the Company’s independent valuer.

INTERNAL AUDIT

The Committee considers at least once a year whether or not there is a need for an internal audit function. Currently it does not consider there to

be a need for an internal audit function, given that there are no employees in the Company and all outsourced functions are with parties who have

their own internal controls and procedures.

EXTERNAL AUDIT

Deloitte LLP has performed the role of External Auditor since the Company’s inception and was retained by the Board during the year as the

External Auditor.

EFFECTIVENESS OF THE AUDIT PROCESS

To fulfil its responsibility regarding the independence of the Auditor, the Committee has considered:

• discussions with or reports from the Auditor describing its arrangements to identify, report and manage any conflicts of interest; and

• the extent of non-audit services provided by the Auditor and arrangements for ensuring the independence and objectivity and robustness

and perceptiveness of the Auditor and their handling of key accounting and audit judgements.

To assess the effectiveness of the Auditor, the Committee has reviewed and challenged:

• the Auditor’s fulfilment of the agreed audit plan and variations from it;

• discussions or reports highlighting the major issues that arose during the course of the audit;

• feedback from other service providers evaluating the performance of the audit team;

• arrangements for ensuring independence and objectivity; and

• robustness of the Auditor in handling key accounting and audit judgements.

The Committee is satisfied with Deloitte’s effectiveness and independence as Auditor, having considered the degree of diligence and professional

scepticism demonstrated by them.

FAIR, BALANCED AND UNDERSTANDABLE

As a result of its review of the Annual Report and accounts, underpinned by its discussions with operating and finance management regarding the

strategic report, and with the finance team regarding the financial statements, the Committee advised the Board that, in the Committee’s view,

the Annual Report and Accounts, taken as a whole, is fair, balanced and understandable and provides the information necessary for shareholders

to assess the Company’s position and performance, business model and strategy.

NON-AUDIT SERVICES

Details of audit and non-audit fees paid to the External Auditor Deloitte LLP during the year are disclosed in Note 7 to the financial statements.

The Committee approved these fees after a review of the level and nature of work to be performed, and are satisfied that they are appropriate

for the scope of the work required. In 2021 the non-audit services were limited to the half-year review which is a non-audit service regularly

requested from the external auditor and consistent with the role.

US SOLAR FUND PLC Annual Report and Financial Statements

During the period, the Audit Committee has requested and approved that an Agreed Upon Procedures engagement be carried out by the

External Auditor, Deloitte LLP. This was to confirm that the recommendations made by a third-party accounting firm in March 2020 in connection

with the Investment Manager's financial controls and processes had been implemented by the Investment Manager. No exceptions were noted

during the review.

The objectivity of the Auditor is reviewed by the Committee which also reviews the terms under which the external Auditor may be appointed to

perform non-audit services. The Committee reviews the scope and results of the audit, its cost effectiveness and the independence

and objectivity of the Auditor, with particular regard to any non-audit work that the Auditor may undertake. In order to safeguard Auditor

independence and objectivity, the Committee ensures that any other advisory and/or consulting services provided by the external Auditor do

not conflict with its statutory audit responsibilities. Advisory and/or consulting services will generally only cover reviews of interim financial

statements, specific and relevant assurance engagements and reporting accountant related work. Any non-audit services conducted by the

Auditor outside of these areas will require detailed consideration and the consent of the Committee before being initiated.

INDEPENDENCE

The Committee is required to consider the independence of the external Auditor. In fulfilling this requirement, the Committee has considered

a report from Deloitte describing its arrangements to identify, report and manage any conflict of interest and the extent of non-audit services

provided by them. The Committee has concluded that it considers Deloitte to be independent of the Company and that the provision of the non-

audit services described above is not a threat to the objectivity and independence of the conduct of the audit.

AUDITOR’S TENURE

The Auditor is required to rotate the audit partner every five years. The current partner is in his third year of tenure having been engaged on an

uninterrupted basis since 30 June 2019. There are no contractual obligations restricting the choice of external auditor and the Company will

consider putting the audit services contract out to tender at least every ten years. In line with the FRC’s recommendations on audit tendering, this

will be considered further when the audit partner rotates every five years. Under the Companies Law, the reappointment of the external Auditor

is subject to shareholder approval at the AGM.

Having carried out the review described above and having satisfied itself that the Auditor remains independent and effective, the Audit

Committee has recommended to the Board that Deloitte be reappointed as Auditor for the year ending 31 December 2022.

ANNUAL GENERAL MEETING

The Chair of the Committee will be present at the Company’s AGM to answer questions on the Audit Committee’s activity and matters within the

scope of the Audit Committee’s responsibilities.

11. Directors’ Remuneration Report

The Board has prepared this report in line with the AIC Code as well as the requirements of the Large and Medium-sized Companies and Groups

(Accounts and Reports) Regulations 2008 (SI2008/410) and the Companies Act 2006.

Under the requirements of Section 497 of the Companies Act 2006, the Company’s Auditor is required to audit certain disclosures contained

within the report. These disclosures have been highlighted and the audit opinion thereon is contained within the Auditor’s Report on pages

73to80.

CONSIDERATION BY THE DIRECTORS OF MATTERS RELATING TO

DIRECTORS’ REMUNERATION

The Remuneration and Nomination Committee comprises the entire Board with Rachael Nutter as Chair. This is considered appropriate as all the

Board members are independent non-executive Directors. The Committee has responsibility for reviewing the remuneration of the Directors,

specifically reflecting the time commitment and responsibilities of the role, and meets at least annually. The Committee also undertakes external

comparisons and reviews to ensure that the levels of remuneration paid are broadly in line with industry standards and members have access to

independent advice where they consider it appropriate.

During the year neither the Board nor the Committee has been provided with external advice or services by any person, but has received

industry comparison information from the Company Secretary in respect of the Directors’ remuneration. Following a review of the Directors’

remuneration after the provision to the Remuneration and Nomination Committee of a proposal to increase fees endorsed by the Investment

Manager, and since there have been no changes to Directors’ fees since inception in 2019, it was agreed that the Directors’ fees would be

increased by 5% as of 1 January 2022. Further details can be found below on page 67.

The remuneration policy set by the Board is described below. Individual remuneration packages are determined by the Remuneration and

Nomination Committee within the framework of this policy.

The Directors are not involved in deciding their own individual remuneration with each Director abstaining from voting on their ownremuneration.

REMUNERATION POLICY

The Company’s remuneration policy is detailed below. This policy was adopted on 19 November 2019 and approved by Shareholders at the 2020

AGM. It will next be put to a vote at the 2023 AGM as part of the regulatory three yearly approval process.

POLICY

The Company’s policy is that the remuneration of Non-Executive Directors should be determined with due regard to the experience of the

Board as a whole, the time commitment required and to be fair and comparable to that of other non-executive Directors of similar companies.

The Company may also periodically choose to benchmark Directors’ fees with an independent review, to ensure they remain competitive, fair

andreasonable.

The fees for the Directors are determined within the limits set out in the Company’s Articles of Association which states that the Directors’

remuneration for their services in the office of director shall, in the aggregate, not exceed £500,000 per annum or such higher figure as the

Company, by ordinary resolution, determines. The Directors may elect to apply the cash amount equal to their annual fee to subscribe for or to

purchase ordinary shares. Directors’ fees will be reviewed at least annually.

The Directors are entitled only to their annual fee and to be reimbursed for any expenses properly and reasonably incurred by them respectively

in and about the business of the Company or in the discharge of his or her duties as a director.

Any director who performs services which in the opinion of the Directors are outside the scope of the ordinary duties of a director, may be paid

such reasonable additional remuneration to be determined by the Directors or any committee appointed by the Directors and such additional

remuneration shall be in addition to any remuneration provided for by way of their annual fee and their reasonable expenses.

No element of the Directors’ remuneration is performance related, nor does any director have any entitlement to pensions, share options or any

long-term incentive plans from the Company.

The Directors hold their office in accordance with the Articles and their appointment letters. No director has a service contract with

the Company, nor is any such contract proposed. The Directors’ appointments can be terminated in accordance with the Articles and

withoutcompensation.

US SOLAR FUND PLC Annual Report and Financial Statements

RETIREMENT BY ROTATION

In accordance with the Articles of Association, the requirements of the AIC Code and the Board’s policy, all the Directors will retire annually and, being

eligible, will offer themselves for re-election. Biographical notes on the Directors are given on page 40. The Board believes that each Director’s skills,

experience and knowledge continue to complement each other and add value to the Company and recommends their re-election to the Board.

DETAILS OF DIRECTORS’ REMUNERATION (AUDITED)

The emoluments in respect of qualifying services of each person who served as a Director during the period are shown below. The Directors

were paid a basic annual fee of £40,000 quarterly in arrears for their services. In addition to this fee, Gill Nott was paid an additional £20,000 per

annum for her role as Chair of the Board. Jamie Richards was paid an additional £10,000 per annum for serving as Chair of the Audit committee.

No Director has waived or agreed to waive any emoluments from the Company in the current year. No other remuneration was paid or payable

by the Company during the current period nor were any expenses claimed by or paid to them other than for expenses incurred wholly, necessarily

and exclusively in furtherance of their duties as Directors of the Company.

Following a review of the Directors’ remuneration in November 2021, it was agreed that the Directors’ fees would increase by 5%, effective

1January 2022 given the review was supported by a peer group fee analysis report prepared by the Company Secretary, it was noted that the

Director fees had not increased since the IPO in 2019 and since then there has been significant ongoing time commitments of the Directors which

included a successful capital raise. The below table shows the Directors’ current fees following this increase as well as the fees paid during theperiod.

12. Management Engagement

Committee’s Report

US SOLAR FUND PLC Annual Report and Financial Statements

The Management Engagement Committee is comprised of the entire Board and chaired by Rachael Nutter. The Committee’s two principal

functions are:

• to review annually the compliance by the Investment Manager with the Company’s investment policy as established by the Board and with the

investment management agreement entered into between the Company and the Investment Manager from time to time (the “Management

Agreement”); and

• to review annually the performance of any other key service providers to the Company.

The Committee is required to report formally to the Board on its findings after each meeting on all matters within its duties and responsibilities.

INVESTMENT MANAGER REVIEW

When reviewing the Investment Manager’s performance, the Committee considers its compliance with the terms of the Management Agreement

as well as its overall performance against the Company’s objectives.

The Committee also reviews the relationship with the Investment Manager including (but not limited to):

• making recommendations on the Investment Manager’s remuneration;

• approving of the terms of engagement of the Investment Manager and the terms of the Management Agreement;

• assessing annually the Investment Manager’s independence and objectivity taking into account relevant regulatory requirements;

• assessing annually the qualifications, expertise and resources of the Investment Manager; and

• meeting regularly with the Investment Manager and at least twice a year, to discuss the Investment Manager’s remits, the performance of the

Company’s investments and any issues arising from the management of the Company’s investments.

The Committee also reviews the level and method of remuneration of the Investment Manager pursuant to the terms of the Management

Agreement, including the methodology of calculation of the relevant annual fee. The review of these fee arrangements seeks to ensure that the

methodology does not encourage excessive risk and that it rewards demonstrably superior performance by the Investment Manager in managing

or advising on the portfolio against the stated investment objective when compared to a suitable benchmark or peer group.

The Investment Manager’s arrangements for its employees and contractors to raise concerns, in confidence, about possible wrongdoing in

financial reporting or other matters are also reviewed by the Committee.

Following its review the Committee considers whether the continuing appointment of the Investment Manager on the agreed terms is in the best

interests of the Company and shareholders and whether any recommendations should be made to the Board in this respect.

OTHER SERVICE PROVIDERS

The Committee also reviews the performance of the Company’s other service providers and in particular:

• monitors compliance by providers of other services to the Company with the terms of their respective agreement from time to time;

• reviews and considers the appointment and remuneration of providers of services to the Company; and

• considers any points of conflict which may arise between the providers of services to the Company.

12. Management Engagement Committee’s Report

US SOLAR FUND PLC Annual Report and Financial Statements

ACTIVITY DURING THE YEAR

The Committee met once in the period under review and all members were present. During this meeting, the Committee’s terms of reference

were reviewed and deemed appropriate.

INVESTMENT MANAGER REVIEW

The Committee also carried out a review of the Investment Manager’s performance, noting the content of the Manager Review Paper on the

Investment Manager’s performance in respect of Investment Process and Performance, Business Process and Business Continuity, Marketing,

Legal, Regulatory and Corporate Governance, and Shareholders Communications. The Committee concluded that the Investment Manager was

performing satisfactorily and had complied with the terms of its engagement and had met its obligations to the Company. The Committee found

that there were a few minor areas of improvement for the Investment Manager in relation to the reporting provided to the Board.

The Committee recommended the Investment Manager’s continued appointment to the Board.

SERVICE PROVIDERS REVIEW

The Committee also carried out a full performance review of all its service providers at its last meeting during which all terms of engagement and

fees were carefully considered by the Committee. The International Standard on Assurance Engagements (ISAE) Report for JTC (UK) Limited

was tabled at a Board Meeting during the period and following its review the Board was satisfied with the controls in place and the performance

of the Company Secretary. The Committee found that the Company’s service providers were all performing satisfactorily.

REPORT ON THE AUDIT OF THE FINANCIAL STATEMENTS

1. OPINION

In our opinion the financial statements of US Solar Fund plc (the ‘company’):

• give a true and fair view of the state of the Company’s affairs as at 31 December 2021 and of its profit for the year then ended;

• have been properly prepared in accordance with United Kingdom adopted international accounting standards; and

• have been prepared in accordance with the requirements of the Companies Act 2006.

We have audited the financial statements which comprise:

• the statement of profit and loss and other comprehensive income statement;

• the statement of financial position;

• the statement of changes in equity;

• the statement of cash flows; and

• the related notes 1 to 24.

The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom adopted international

accounting standards.

2. BASIS FOR OPINION

We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under

those standards are further described in the auditor’s responsibilities for the audit of the financial statements section of our report.

We are independent of the Company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the

UK, including the Financial Reporting Council’s (the ‘FRC’s’) Ethical Standard as applied to listed public interest entities, and we have fulfilled our

other ethical responsibilities in accordance with these requirements. The non-audit services provided to the Company for the year are disclosed

in Note 7 to the financial statements. We confirm that we have not provided any non-audit services prohibited by the FRC’s Ethical Standard to

thecompany.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

3. SUMMARY OF OUR AUDIT APPROACH

Key audit matters The key audit matter that we identified in the current year was:

• Fair value of investments

Within this report, key audit matters are identified as follows:

Newly identified

Increased level of risk

Similar level of risk

Decreased level of risk

Materiality The materiality that we used in the current year was $4.87million which was determined on the

basis of 1.5% of total shareholders equity.

Scoping As the Company is required to measure its subsidiaries at fair value rather than consolidate on a

line-by-line basis, the Company has been treated as having only one component.

Significant changes in our approach There have been no significant changes to our audit approach in the current period.

US SOLAR FUND PLC Annual Report and Financial Statements

4. CONCLUSIONS RELATING TO GOING CONCERN

In auditing the financial statements, we have concluded that the directors’ use of the going concern basis of accounting in the preparation of the

financial statements is appropriate.

Our evaluation of the directors’ assessment of the Company’s ability to continue to adopt the going concern basis of accounting included:

• evaluating the Company’s liquidity requirements and forecast cashflows over the assessment period;

• evaluating of the Company’s investment commitments and opportunities alongside the funding strategy and availability of existing facilities;

• assessing the assumptions used in the forecast cashflows, including performing sensitivity analysis in relation to key assumptions; and

• assessing the amount of headroom in the forecasts.

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or

collectively, may cast significant doubt on the Company’s ability to continue as a going concern for a period of at least twelve months from when

the financial statements are authorised for issue.

In relation to the reporting on how the Company has applied the UK Corporate Governance Code, we have nothing material to add or draw

attention to in relation to the directors’ statement in the financial statements about whether the directors considered it appropriate to adopt the

going concern basis of accounting.

Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.

5. KEY AUDIT MATTERS

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements of the

current period and include the most significant assessed risks of material misstatement (whether or not due to fraud) that we identified. These

matters included those which had the greatest effect on: the overall audit strategy, the allocation of resources in the audit; and directing the

efforts of the engagement team.

These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do

not provide a separate opinion on these matters.

5.1. FAIR VALUE OF INVESTMENTS

Key audit

matter

description

The company’s investments held at fair value, comprise of investments in an intermediate holding company and its associated

debt interest. The subsidiary entity holds investments in solar power assets.

The company has made six investments via this subsidiary entity as at 31 December 2021. The total value of investments,

including loan receivables, recognised at fair value as at the reporting date is $314.4million (2020: $195.3million).

The valuation of investments requires significant judgements given there is no liquid or quoted price information available for

the investments made. Critical assumptions used to derive fair value include forecast power generation, power price forecasts

operational expenses, economic life of operational assets and discount rates applied to future cashflows.

Due to the inherent risks described above we have identified a risk of error and a potential fraud risk relating to the possibility

that investments may be valued inappropriately.

A breakdown of the investments and the assumptions applied to the valuation are described in Note 10 and Note 17 of the

financial statements. Detail of the accounting policy applied by the Company is set out in Note 5 with details in respect of the

valuation approach and methodology set out in Note 17.

US SOLAR FUND PLC Annual Report and Financial Statements

How the

scope of

our audit

responded to

the key audit

matter

The timing, nature and extent of our audit procedures were directed to assess the appropriateness of management’s

assessment of fair value of investments at the reporting date. As such we have considered evidence available to support the

assumptions made by management and the sensitivity of the valuation to reasonably possible changes in these assumptions.

We challenged these assumptions and the valuation recognised through the following procedures:

• obtaining an understanding of the relevant controls related to the valuation process at 31 December 2021;

• reviewing legal documentation and correspondence related to the acquisition of investments to assess whether the

Company has the rights and obligations to recognise the investments at the reporting date;

• assessing of the methodology applied in determining fair value and challenge of key assumptions through the use of

benchmarking against third party sources;

• engaging with valuation specialists to assess and evaluate the valuation methodology applied, the financial models prepared

by management and key assumptions adopted including discount rates, merchant price assumptions and useful economic

life assumptions;

• challenging key assumptions, including consideration of the impact of climate change, through consideration of other

sources of macroeconomic and observable market data ;

• evaluating the arithmetic accuracy of the models prepared by management;

• reviewing the share purchase agreements for any newly acquired assets in order to agree the acquisition cost, the

nature and amount of any deferred consideration that may be embedded in the valuation and the impact of financing and

investment structures, including tax equity investments, on the valuations recognised;

• performing sensitivity analysis over key assumptions to assess the impact on valuations recognised; and

• evaluating the adequacy of the disclosures made in the financial statements.

Key

observations

Based on the audit procedures performed we have concluded that the valuation of investments recognised are appropriate.

6. OUR APPLICATION OF MATERIALITY

6.1. MATERIALITY

We define materiality as the magnitude of misstatement in the financial statements that makes it probable that the economic decisions of a

reasonably knowledgeable person would be changed or influenced. We use materiality both in planning the scope of our audit work and in

evaluating the results of our work.

Based on our professional judgement, we determined materiality for the financial statements as a whole as follows:

Materiality $4.87million (2020: $3.8million)

Basis for

determining

materiality

1.5% of total shareholders equity (2020: 2% of total shareholders equity)

Rationale

for the

benchmark

applied

We consider total shareholders equity to be the key benchmark used by members of the Company in assessing financial

performance. Net asset value is a key metric communicated to shareholders and investors and, due to the nature of the

Company as an investment entity, reflects both the performance and position of the Company. In the current year a lower

benchmark was applied reflecting the increasing maturity of the fund.

A lower materiality threshold of $0.14million based upon 5% of expenses (2020: $0.14million based on 5% of expenses) has also been applied

to all administrative expenses and related balances recognised within the statement of financial position at the reporting date. The use of a lower

materiality threshold reflects the nature of these transactions being primarily from related parties.

Materiality

Total Shareholders Equity

Total Shareholders

Equity $324m

Materiality $4.87m

Audit Committee

Reporting Threshold

$0.20m

6.2. PERFORMANCE MATERIALITY

We set performance materiality at a level lower than materiality to reduce the probability that, in aggregate, uncorrected and undetected

misstatements exceed the materiality for the financial statements as a whole. Performance materiality was set at 70% of materiality for the 2021

audit (2020: 70%). In determining performance materiality, we considered the following factors:

• our understanding of the control environment relevant to the financial reporting process;

• no significant changes in the business during the year against the expected business plan and strategy;

• relative complexity of operations and stage of investment lifecycle in the current period.

6.3. ERROR REPORTING THRESHOLD

We agreed with the Audit Committee that we would report to the Committee all audit differences in excess of $0.20million (2020: $0.19million),

as well as differences below that threshold that, in our view, warranted reporting on qualitative grounds. We also report to the Audit Committee

on disclosure matters that we identified when assessing the overall presentation of the financial statements.

7. AN OVERVIEW OF THE SCOPE OF OUR AUDIT

7.1. SCOPING

Our audit was scoped by obtaining an understanding of the entity and its environment, including internal control, and assessing the risks of

material misstatement. Audit work to respond to the risks of material misstatement was performed directly by the audit engagement team.

As the Company is required to measure its subsidiaries at fair value rather than consolidate on a line-by-line basis, the Company has been treated

as having only one component and thus all of the work was carried out by one audit team.

7.2. OUR CONSIDERATION OF THE CONTROL ENVIRONMENT

We did not plan to take a controls reliance approach in the current year and we therefore adopted a non-controls reliance approach with

ourtesting.

7.3. OURCONSIDERATIONOFCLIMATE-RELATEDRISKS

Management has considered transition and physical risks when factoring in climate change as part of their risk assessment process when

considering the principal risks and uncertainties facing the Company. This is set out in the strategic report on pages 21 to 27 and the principal

risks set out on pages 29 to 34. From the financial statements’ perspective, these risks have been focused on the valuation of investments. This

is consistent with our evaluation of the climate-related risks facing the Company and is linked to the key audit matter as highlighted in section 5.1

above. In addition, we have:

• Challenged how the directors considered climate change in their assessment of going concern based on our understanding of the business

environment and by benchmarking relevant assumptions with market data.

• Involved our Environmental Social and Governance (ESG) specialist in assessing the Task Force for Climate related Financial Disclosures

(TCFD) on pages 21 to 27 against the recommendations of the TCFD framework.

• Read the climate risk disclosures included throughout the strategic report section of the annual report to consider whether they are

materially consistent with the financial statements and our knowledge obtained in the audit.

US SOLAR FUND PLC Annual Report and Financial Statements

8. OTHER INFORMATION

The other information comprises the information included in the annual report, other than the financial statements and our auditor’s report

thereon. The directors are responsible for the other information contained within the annual report.

Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report,

we do not express any form of assurance conclusion thereon.

Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the

financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated.

If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material

misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement

of this other information, we are required to report that fact.

We have nothing to report in this regard.

9. RESPONSIBILITIES OF DIRECTORS

As explained more fully in the directors’ responsibilities statement, the directors are responsible for the preparation of the financial statements

and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the

preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the directors are responsible for assessing the Company’s ability to continue as a going concern, disclosing

as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the

Company or to cease operations, or have no realistic alternative but to do so.

10. AUDITOR’S RESPONSIBILITIES FOR THE AUDIT OF THE

FINANCIALSTATEMENTS

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement,

whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is

not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements

can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the

economic decisions of users taken on the basis of these financial statements.

A further description of our responsibilities for the audit of the financial statements is located on the FRC’s website at: www.frc.org.uk/

auditorsresponsibilities. This description forms part of our auditor’s report.

11. EXTENT TO WHICH THE AUDIT WAS CONSIDERED CAPABLE OF

DETECTING IRREGULARITIES, INCLUDING FRAUD

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities,

outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of

detecting irregularities, including fraud is detailed below.

11.1.IDENTIFYINGANDASSESSINGPOTENTIALRISKSRELATEDTOIRREGULARITIES

In identifying and assessing risks of material misstatement in respect of irregularities, including fraud and non-compliance with laws and

regulations, we considered the following:

• the nature of the industry and sector, control environment and business performance including the design of the Company’s

remunerationpolicies;

• results of our enquiries of management and the audit committee about their own identification and assessment of the risks of irregularities;

• any matters we identified having obtained and reviewed the Company’s documentation of their policies and procedures relating to:

– identifying, evaluating and complying with laws and regulations and whether they were aware of any instances of non-compliance;

– detecting and responding to the risks of fraud and whether they have knowledge of any actual, suspected or alleged fraud;

– the internal controls established to mitigate risks of fraud or non-compliance with laws and regulations;

• the matters discussed among the audit engagement team and relevant internal specialists, including tax, ESG and valuations specialists,

regarding how and where fraud might occur in the financial statements and any potential indicators of fraud.

US SOLAR FUND PLC Annual Report and Financial Statements

As a result of these procedures, we considered the opportunities and incentives that may exist within the organisation for fraud and identified

the greatest potential for fraud in the fair value of the investments. In common with all audits under ISAs (UK), we are also required to perform

specific procedures to respond to the risk of management override.

We also obtained an understanding of the legal and regulatory framework that the Company operates in, focusing on provisions of those laws

and regulations that had a direct effect on the determination of material amounts and disclosures in the financial statements. The key laws

and regulations we considered in this context included the UK Companies Act, Listing Rules, tax legislation and Alternative Investment Fund

Managers (AIFM) Directive, Non-Mainstream Pooled Investments regulations.

In addition, we considered provisions of other laws and regulations that do not have a direct effect on the financial statements but compliance

with which may be fundamental to the Company’s ability to operate or to avoid a material penalty.

11.2.AUDITRESPONSETORISKSIDENTIFIED

As a result of performing the above, we identified fair value of investments as a key audit matter related to the potential risk of fraud. The key

audit matters section of our report explains the matter in more detail and also describes the specific procedures we performed in response to that

key audit matter.

In addition to the above, our procedures to respond to risks identified included the following:

• reviewing the financial statement disclosures and testing to supporting documentation to assess compliance with provisions of relevant laws

and regulations described as having a direct effect on the financial statements;

• enquiring of management and the audit committee concerning actual and potential litigation and claims;

• performing analytical procedures to identify any unusual or unexpected relationships that may indicate risks of material misstatement due

tofraud;

• reading minutes of meetings of those charged with governance; and

• in addressing the risk of fraud through management override of controls, testing the appropriateness of journal entries and other

adjustments; assessing whether the judgements made in making accounting estimates are indicative of a potential bias; and evaluating the

business rationale of any significant transactions that are unusual or outside the normal course of business.

We also communicated relevant identified laws and regulations and potential fraud risks to all engagement team members including internal

specialists, and remained alert to any indications of fraud or non-compliance with laws and regulations throughout the audit.

FOR THE YEAR END

ED 31 DECEMBER 2021

1. GENERAL INFORMATION

US Solar Fund plc (the Company) was incorporated as a Public Company, limited by shares, in England and Wales on 10 January 2019 with

registered number 11761009. The registered office of the Company is The Scalpel, 18th Floor, 52 Lime Street, London EC3M 7AF. Its share

capital is denominated in US Dollars and currently consists of ordinary shares. The Company’s principal activity is to invest in a diversified

portfolio of Solar Power Assets located in North America and other countries forming part of the Organisation for Economic Co-operation and

Development (OECD) in the Americas.

2. BASIS OF PREPARATION

The financial statements have been prepared in accordance with UK-adopted international accounting standards and also considers Statement

of Recommended Practice “Financial Statements of Investment Trust Companies and Venture Capital Trusts”, issued by the Association of

Investment Companies, (the AIC SORP) in April 2021. The financial statements have been prepared on a historical cost basis, except where

balances are recognised at fair value. The principal accounting policies are set out in Note 5.

In terms of the AIC SORP, the Company presents a Statement of Profit and Loss and Other Comprehensive Income, which shows amounts split

between those which are revenue and capital in nature.

The determination of the revenue or capital nature of a transaction is determined by giving consideration to the underlying elements of the

transaction and is carried out in accordance with the recommendations and principles as set out in the AIC SORP. Capital transactions are

considered to be those arising as a result of the appreciation or depreciation in the value of assets, whether due to the retranslation of assets held

in foreign currency or fair value movements on investments held at fair value through profit and loss.

Revenue transactions are all transactions, other than those which have been identified as capital in nature.

FUNCTIONAL AND PRESENTATION CURRENCY

The currency of the primary economic environment in which the Company operates (the functional currency) is US Dollar, which is also the

presentation currency.

GOING CONCERN

The financial position of the Company, its cash flows, liquidity position and borrowing facilities are described in the financial statements and

related notes. In addition, Note 16 to the financial statements includes the policies and processes for managing its capital, its financial risk

management, details of its financial instruments and its exposure to credit risk and liquidity risk. The impact of COVID-19 is detailed in the

Investment Manager’s report on page 12. In the opinion of the Directors, the Company has sufficient financial resources and expectation of

growth in the medium-term to meet its financial obligations.

The Company generated profit after tax of $15.0 million and operating cash flows of $5.7 million for the year. As at 31 December 2021, the

Company is in a net current asset position of $9.6million, comprised of cash ($16.2 million) and receivables ($0.2 million) in excess of dividends

payable ($5.0 million) and other payables ($1.9 million). As of the same date, the Company’s subsidiary, USF Holding Corp., has available cash of

$21.0 million, which is available to meet the obligations of the Company. As such the Directors believe that the Company will continue into the

foreseeable future and have adopted the going concern basis of preparation in preparing these financial statements. In September 2021, the

Company (through a wholly owned US subsidiary) upsized its existing revolving credit facility with Fifth Third Bank National Association (RCF)

from $25million to S40million. With an undrawn balance as at 31 December 2021, the RCF provides liquidity for capital expenditures, working

capital and general corporate purposes, including funds to acquire the second tranche of MS2.

US SOLAR FUND PLC Annual Report and Financial Statements

3. CRITICAL JUDGEMENTS AND KEY SOURCES OF

ESTIMATIONUNCERTAINTY

The preparation of the financial statements requires management to make judgements, estimates and assumptions that affect the application

of accounting policies and the reported amount of assets, liabilities, income and expenses. Estimates and underlying assumptions are reviewed

on an ongoing basis. Revisions to the accounting estimates are recognised in the period in which the estimates are revised and in any future

periodsaffected.

During the year, the Directors considered the following significant judgements, estimates and assumptions:

JUDGEMENTS

ASSESSMENT AS AN INVESTMENT ENTITY

Entities that meet the definition of an investment entity within IFRS 10 are required to measure their subsidiaries at fair value through profit or

loss rather than consolidate them unless they provided investment related services to the Company. To determine that the Company continues to

meet the definition of an investment entity, the Company is required to satisfy the following three criteria:

a) the Company obtains funds from one or more investors for the purpose of providing those investors with investment management services;

b) the Company commits to its investors that its business purpose is to invest funds solely for returns from capital appreciation, investment

income, or both; and

c) the Company measures and evaluates the performance of substantially all of its investments on a fair value basis. The Company meets the

criteria as follows:

• the Company provides investment management services and has several investors who pool their funds to gain access to infrastructure

related investment opportunities that they might not have had access to individually;

• the stated strategy of the Company is to deliver stable returns to shareholders through investing in a diversified portfolio of utility-scale

solar power plants and associated infrastructure, which may include transmission and storage (e.g. battery) assets which will typically

be co-located with the solar power plant (together, Solar Power Assets) located in North America and other OECD countries in the

Americas; and

• the Company measures and evaluates the performance of all of its investments on a fair value basis. The fair value method is used to

represent the Company’s performance in its communication to the market, including investor presentations. In addition, the Company

reports fair value information internally to Directors, who use fair value as the primary measurement attribute to evaluate performance.

The Directors are of the opinion that the Company has all the typical characteristics of an investment entity and continues to meet the definition

in the standard. This conclusion will be reassessed on an annual basis.

In respect of the second criterion the Company’s purpose is to invest funds for returns from capital appreciation and investment income. In

respect of the requirement that investments should not be held indefinitely but should have an exit strategy for their realisation the Company

may hold these assets until the end of their expected useful lives, unless there is an opportunity in the market to dispose of the investments

at a price that is considered appropriate. There continues to be an active secondary market for renewables projects in the countries in which

weoperate.

As at 31 December 2021, the Company only had one subsidiary, USF Holding Corp. Being an investment entity, it is measured at fair value

as opposed to being consolidated on a line-by-line basis, meaning its cash, debt and working capital balances are included in the fair value of

investments rather than the Group’s current assets.

ESTIMATES

VALUATION OF INVESTMENT IN SUBSIDIARY

The significant estimate in the Company’s financial statements that carry the most significant risk of a material effect on next year’s financial

statements are the fair value of investments. This estimate is considered to be at risk of actual outcomes in the next 12 months varying from

the estimates made in determining discount rates applied in calculating the reported amount of an asset, as the assumptions used are subject to

measurement uncertainty and possible changes could be significant. Refer to Note 17 for further year-end detail on the fair value measurement

as at 31 December 2021 and detail on the sensitivity analysis on inputs including discount rate, electricity production, electricity prices and

operational expenses.

US SOLAR FUND PLC Annual Report and Financial Statements

4. NEW AND REVISED STANDARDS AND INTERPRETATIONS

APPLICATION OF NEW AND REVISED STANDARDS

The accounting policies adopted in the preparation of the Annual Report and Audited Financial Statements for the year ended 31 December

2021 are consistent with those of the previous financial year. The adoption of new standards, interpretations and amendments in the current year

has not had a material impact. The Company has not early adopted any standard, interpretation or amendment that has been issued but is not yet

effective at 31 December 2021.

NEW AND REVISED STANDARDS IN ISSUE BUT NOT YET EFFECTIVE

The following standards have been issued but are not effective for this accounting period and have not been adopted early:

• IAS 1 (amended) – Amendments regarding classifications of liabilities, and disclosure of accounting policies – effective from 1 January 2023

• IAS 8 (amended) – Amendments regarding the definition of accounting estimates – effective from 1 January 2023.

• IAS 12 (amended) – Amendments regarding deferred tax on leases and decommissioning obligations – effective from 1 January 2023.

Adoption of the new or amended standards and relevant interpretations in future periods is not expected to have a material impact on the

financial statements of the Company.

5. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting policies used in the preparation of the financial statements have been consistently applied during the year ended 31 December

2021 as well as the prior period.

The principal accounting policies applied in the preparation of the financial statements are set out below:

SEGMENTAL INFORMATION

The Board is of the opinion that the Group is engaged in a single segment business, being the investment in Solar Power Assets located in North

America and other countries forming part of the OECD in the Americas.

INCOME

Income comprises interest income (bank interest and loan interest). Interest income is recognised when it is probable that the economic benefits

will flow to the Company and the amount of revenue can be measured reliably. Loan interest income is accrued by reference to the principal

outstanding and at the effective interest rate applicable, which is the rate that exactly discounts estimated future cash receipts through the

expected life of the financial asset to that asset’s net carrying amount on initial recognition. Dividend income is recognised in profit or loss on the

date on which the Group’s right to receive payment is established.

No income is earned from contracts with customers and as such IFRS 15 has not been applied.

EXPENSES

Operating expenses are the Company’s costs incurred in connection with the on-going management of the Company’s investments and

administrative costs. Operating expenses are accounted for on an accruals basis.

The Company’s management and administration fees, finance costs and all other expenses are charged through the Statement of Profit and Loss

and Other Comprehensive Income.

Directly attributable acquisition costs of assets are capitalised on purchase of assets. Costs directly relating to the issue of ordinary shares are

charged to share premium.

NET GAIN OR LOSS ON INVESTMENTS AT FAIR VALUE THROUGH PROFIT

ANDLOSS

The Company recognises movements in the fair value of investments in subsidiaries through profit and loss.

US SOLAR FUND PLC Annual Report and Financial Statements

TAXATION

The Company is approved as an Investment Trust Company under sections 1158 and 1159 of the Corporation Taxes Act 2010 and Part 2 Chapter

1 Statutory Instrument 2011/2999 for accounting periods commencing on or after 25 May 2018. The approval is subject to the Company

continuing to meet the eligibility conditions of the Corporations Tax Act 2010 and the Statutory Instrument 2011/2999. The Company intends

to ensure that it complies with the Investment Trust Company regulations on an ongoing basis and regularly monitors the conditions required to

maintain Investment Trust Company status.

From 1 April 2015 there is a single corporation tax rate of 19%. Tax is recognised in the Statement of Profit and Loss and Other Comprehensive

Income except to the extent that it relates to the items recognised as direct movements in equity, in which case it is similarly recognised as a

direct movement in equity. Current tax is the expected tax payable on any taxable income for the period, using tax rates enacted or substantively

enacted at the end of the relevant period.

INVESTMENT IN SUBSIDIARIES

Subsidiaries are entities controlled by the Company. Control exists when the Company is exposed, or has rights, to variable returns from its

involvement with the subsidiary entity and has the ability to affect those returns through its power over the subsidiary entity.

In accordance with the exception under IFRS 10 Consolidated financial statements, an investment entity is not required to consolidate its

subsidiaries where certain conditions are met, therefore it is required to account for its investments in subsidiaries at fair value. The Company

recognizes the movements in fair value of investments in subsidiaries through profit and loss. See Note 17 to the Financial Statements for a

summary of the fair value movement over the period along with the valuation process and methodology

The Company does not have any subsidiaries that provide investment management services and are not themselves investment entities. As a

result the Company, being an investment entity, does not consolidate any of its subsidiaries.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents comprise cash at bank and deposits held with the bank, with an original maturity of three months or less that are

readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value.

TRADE AND OTHER RECEIVABLES

Trade and other receivables are recognised initially at fair value and subsequently stated at amortised cost less loss allowance which is calculated

using the provision matrix of the expected credit loss model, the effect of which is considered immaterial.

TRADE AND OTHER PAYABLES

Trade and other payables are recognised initially at fair value and subsequently stated at amortised cost.

EQUITY

Equity instruments issued by the Company are recorded at the amount of the proceeds received, net of directly attributable issue costs. Costs

not directly attributable to the issue are immediately expensed in the Statement of Profit and Loss and Other Comprehensive Income. The

Company’s capital is represented by the Ordinary Shares, Share Premium (until cancellation), Accumulated losses and Capital Reduction Reserve.

FINANCIAL INSTRUMENTS

In accordance with IFRS 9, the Company classifies its financial assets and financial liabilities at initial recognition into the categories of amortised

cost or fair value through profit or loss. None of the financial instruments are classified as fair value through other comprehensive income.

FINANCIAL ASSETS

The Company classifies its financial assets at amortised cost or fair value through profit or loss on the basis of both:

• the entity’s business model for managing the financial assets

• the contractual cash flow characteristics of the financial asset.

FINANCIAL ASSETS MEASURED AT AMORTISED COST

A debt instrument is measured at amortised cost if it is held within a business model whose objective is to hold financial assets in order to collect

contractual cash flows and its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on

the principal amount outstanding. The Company includes in this category short-term non-financing receivables including cash and financial

instruments classified as trade and other receivables.

US SOLAR FUND PLC Annual Report and Financial Statements

FINANCIAL ASSET MEASURED AT FAIR VALUE THROUGH PROFIT OR LOSS

(FVPL)

A financial asset is measured at fair value through profit or loss if:

a) its contractual terms do not give rise to cash flows on specified dates that are solely payments of principal and interest (SPPI) on the principal

amount outstanding; or

b) it is not held within a business model whose objective is either to collect contractual cash flows, or to both collect contractual cash flows and

sell; or

c) it is classified as held for trading (derivative contracts in an asset position).

The Company’s investment in subsidiaries (which comprises both debt and equity) is held at fair value through profit or loss under IFRS 9 as

the equity portion of the investment does not meet the SPPI test nor will the Company elect to designate the investments at fair value through

other comprehensive income. The debt investment forms part of a group of assets that are managed and the performance evaluated on a fair

valuebasis.

The Company includes in this category equity instruments including investments in subsidiaries (which comprises both debt and equity). There

are no consolidated subsidiaries.

FINANCIAL LIABILITIES MEASURED AT AMORTISED COST

This category includes all financial liabilities, other than those measured at fair value through profit or loss, including short-term payables.

RECOGNITION AND DERECOGNITION

Financial assets are recognised on trade date, the date on which the Company commits to purchase or sell an asset. A financial asset is

derecognised where the rights to receive cash flows from the asset have expired, or the Company has transferred its rights to receive cash flows

from the asset. The Company derecognises a financial liability when the obligation under the liability is discharged, cancelled or expired.

IMPAIRMENT OF FINANCIAL ASSETS

The company holds trade receivables with no financing component and which have maturities of less than 12 months at amortised cost

and, as such has chosen to apply an approach similar to the simplified approach for expected credit losses (ECL) under IFRS 9 to all of its

tradereceivables.

Interest receivable on cash balances, fall within the scope of IFRS 9. The Company has completed some high-level analysis and forward looking

qualitative and quantitative information, the Directors consider the interest receivable to be low credit risk as the deposits are held with reputable

financial institutions.

For interest receivable that are low credit risk, IFRS 9 allows a 12 month expected credit loss to be recognised. The Directors have concluded

that any ECL on the interest receivable would be immaterial to the Annual Financial Statements and therefore no impairment adjustments were

accounted for.

Investment held at fair value through profit or loss is not subject to IFRS 9 impairment requirements.

FAIR VALUE MEASUREMENT AND HIERARCHY

Fair value is the price that would be received on the sale of an asset, or paid to transfer a liability, in an orderly transaction between market

participants at the measurement date. The fair value measurement is based on the presumption that the transaction takes place either in the

principal market for the asset or liability, or in the absence of a principal market, in the most advantageous market. It is based on the assumptions

that market participants would use when pricing the asset or liability, assuming they act in their economic best interest. A fair value measurement

of a non-financial asset takes into account the best and highest value use for that asset.

US SOLAR FUND PLC Annual Report and Financial Statements

The level in the fair value hierarchy within which the fair value measurement is categorised is determined on the basis of the lowest level input

that is significant to the fair value measurement in its entirety. For this purpose significance of the inputs is assessed against the fair value

measurement in its entirety. Assessing the significance of a particular input to the fair value measurement in its entirety requires judgement,

considering factors specific to the asset or liability. If a fair value measurement uses observable inputs that require significant adjustment based

on unobservable inputs or any other significant unobservable inputs, that measurement is a Level 3 measurement.

The fair value hierarchy to be applied under IFRS 13 is as follows:

Level 1: Quoted (unadjusted) market prices in active markets for identical assets or liabilities.

Level 2: Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable.

Level 3: Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

For assets and liabilities that are carried at fair value and which will be recorded in the financial information on a recurring basis, the Company will

determine whether transfers have occurred between levels in the hierarchy by reassessing categorisation at the end of each reporting period.

8. TAXATION

The Company is approved as an Investment Trust Company with effect as of 16 April 2019 and is subject to tax at the UK corporation tax rate of

19%. An Investment Trust Company can claim a corporation tax deduction for dividends designated as interest distributions that are derived from

net interest income. Therefore, no UK corporation tax charge has been recognised by the Company for the period ended 31 December 2021.

The tax credit of $376,563 (2020: $41,823) arose as a result of dividends payable in respect of the year being designated as interest distributions

in accordance with UK tax legislation specific to Investment Trust Companies. Investment Trust Companies which have been approved by HM

Revenue & Customs are exempt from UK corporation tax on their capital gains. Due to the Company’s status as an approved Investment Trust

Company, and the intention to continue meeting the conditions required to maintain that approval for the foreseeable future, the Company has

not provided for deferred tax in respect of any gains or losses arising on the revaluation of its investments. The Company has an unrecognised

deferred tax asset of $36,288 (2020: $19,465) in respect of tax losses which are available to be carried forward and offset against future taxable

profits. A deferred tax asset has not been recognised as it is considered unlikely that the Company will generate taxable profits in excess of

deductible expenses in future periods. The unrecognised deferred tax asset has been calculated using a corporation tax rate of 25% (2020: 19%).

9. EARNINGS PER SHARE

Earnings per share amounts are calculated by dividing the profit or loss for the year attributable to ordinary equity holders of the Company by the

weighted average number of ordinary shares in issue during the year. As there are no dilutive instruments outstanding, basic and diluted earnings

per share are identical.

were issued in the prior year to the Investment Manager in accordance with the fee arrangement established in the IPO Prospectus. During the

current year Investment Manager acquired 221,176 (2020:Nil) at an average price of $1.01 per share, reflecting the Management Share Amount

16. FINANCIAL RISK MANAGEMENT

The Company is exposed to certain risks through the ordinary course of business and the Company’s financial risk management objective is to

minimise the effect of these risks. The management of risks is performed by the Directors of the Company and the exposure to each financial risk

considered potentially material to the Company, how it arises and the policy for managing it is summarised below:

CREDIT RISK

The Company is exposed to third-party credit risk in several instances and the possibility that counterparties with which the Company and its

subsidiaries, together the Group, contracts may fail to perform their obligations in the manner anticipated by the Group.

Counterparty credit risk exposure limits are determined based on the credit rating of the counterparty. Counterparties are assessed and

monitored on the basis of their ratings from Standard & Poor’s and/or Moody’s. No financial transactions are permitted with counterparties with

a credit rating of less than BBB- from Standard & Poor’s or Baa3 from Moody’s unless specifically approved by the Board.

Cash and other assets that are required to be held in custody will be held at bank. Cash and other assets may not be treated as segregated assets

and will therefore not be segregated from the banks own assets in the event of the insolvency of a custodian. Cash held with the bank will not be

treated as client money subject to the rules of the FCA and may be used by the bank in the ordinary course of its own business. The Company will

therefore be subject to the creditworthiness of the bank. In the event of the insolvency of the bank, the Company will rank as a general creditor in

relation thereto and may not be able to recover such cash in full, or at all.

Credit risk is mainly at subsidiary level where the capital commitments are being made and is managed by diversifying exposures among a

portfolio of counterparties and through applying credit limits to those counterparties with lower credit standing.

Credit exposures may also be managed using credit derivatives. No credit derivatives were in place as at 31 December 2021.

Cash and bank deposits are held with major international financial institutions who each hold a Moody’s credit rating of A2 or higher.

US SOLAR FUND PLC Annual Report and Financial Statements

LIQUIDITY RISK

The objective of liquidity management is to ensure that all commitments which are required to be funded can be met out of readily available and

secure sources of funding. The Company’s only financial liabilities are trade and other payables. The Company intends to hold sufficient cash

across the Company and Subsidiary’s operating accounts to meet the working capital needs over a horizon of at least the next 6 months. Cash

held at subsidiary level is available to meet the obligations of the Company. As at 31 December 2021 USF Holding Corp. held cash at bank of

$21,038,132 and had trade and other payables totalling $583,028. Cash flow forecasts are prepared on a monthly basis for a rolling 2-year

period to assist in the ongoing analysis of short-term cash flow.

MARKET RISK

Market risk is the risk that the fair value or cash flows of a financial instrument will fluctuate due to changes in market prices. Market risk

reflects: (i) other price risks, (ii) interest rate risk, and (iii) currency risk. The objective is to minimise market risk through managing and controlling

these risks to acceptable parameters, while optimising returns. The Company uses financial instruments in the ordinary course of business in

order to manage market risks. Further commentary on financial and market risks is provided in the Principal Risks and Uncertainties section,

includinginflation.

(i) PRICE RISK

Price risk is the risk that the fair value or cash flows of a financial instrument will fluctuate due to changes in market prices. At 31 December 2021,

the Company had no direct exposure to price risk. The effect of price on the Company’s investments is considered in Note 17.

US SOLAR FUND PLC Annual Report and Financial Statements

(ii) INTEREST RATE RISK

Interest rate Risk is the risk of changes in the interest expense for debt, or interest received on deposits, as measured in the currency of that debt,

due to movements in market interest rates.

The Company does not have any borrowings as at 31 December 2021. The Company may manage the cost of borrowing by borrowing using fixed

rate instruments, and/or by overlaying interest rate derivatives against the Company’s debt portfolio. Policy limits for the maximum and minimum

levels of hedging relative to the expected net debt profile for rolling multi-year periods.

In considering whether to execute hedging transactions, the costs and benefits of hedging will be balanced against the effects of movements in

interest rates on the debt portfolio.

At 31 December 2021, the Company is indirectly exposed to interest rate risk through its investment in the subsidiary. However this risk is

managed through interest rate swaps at a subsidiary level and the effect of Interest rate risk on the Company is considered immaterial.

The Company may be exposed to changes in variable market rates of interest as this could impact the discount rate and therefore the valuation of

the projects as well as the fair value of the loan to subsidiary.

(iii) CURRENCY RISK

The Net Asset Value of the Company is calculated in US Dollars whereas the financial instruments at year end may be in other currencies. The

value in terms of USD of the financial instruments of the Company, which may be designated in any currency, may rise and fall due to exchange

rate fluctuations of individual currencies. Adverse movements in currency exchange rates can result in a decrease and loss of capital. At year end,

the currency exposure was considered immaterial.

Currency risk can be mitigated to some extent through transacting wherever possible in USD. Where non-USD exposures are unavoidable, the

Company is able to manage exposures to movements in foreign currencies through foreign exchange derivative transactions.

CAPITAL RISK MANAGEMENT

The capital structure of the Company at year-end consists of equity attributable to equity holders of the Company, comprising issued capital,

reserves and accumulated loss. The Company has no return on capital benchmark, but the Board continues to monitor the balance of the overall

capital structure so as to maintain investor and market confidence. The Company is not subject to any external capital requirements.

US SOLAR FUND PLC Annual Report and Financial Statements

The Company’s policy is to recognise transfers into and transfers out of fair value hierarchy levels as of the date of the event or change in

circumstances that caused the transfer.

In accordance with the guidelines of the Company’s valuation policy, all assets held as at 31 December 2021 have been valued by an external

valuation expert, as they are now fully operational.

VALUATION APPROACH AND METHODOLOGY

Fair value for operational Solar Assets is derived using a discounted cash flow ( DCF) methodology. For Solar Assets that are not yet operational

or where the completion of the acquisition by the Company has not occurred at the time of valuation, the purchase price of the Solar Power Asset

including 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.

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. Given the long-term nature of the assets, valuations are assessed using long-term

historical data to reflect the asset life.

Where possible, assumptions are based on observable market and technical data. The Investment Manager also engages technical experts such as

independent engineers and long-term electricity price forecasters to provide long-term data 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. These two electricity price forecasts are averaged and provided to the independent valuer to

project the prices at which existing power purchase agreements will be re-contracted. A blend of 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, 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.

VALUATION PROCESS

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 United States with significant experience in estimating the fair value of solar and other renewable energy assets. In

accordance with Company policy, all 42 operating assets were externally valued at 31 December 2021. The valuation has been calculated in

accordance with Uniform Standards of Professional Appraisal Practice (USPAP) as applied to photovoltaic electricity generation systems in the

United States.

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 at

cost for 31 December 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 31 December 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 compare the implied post-tax discount rate.

As at 31 December 2021, the weighted average discount rate range used was 6.3% (December 2020: 6.7%) on a WACC basis, and

7.8% (December 2020: 8.3%) on a pre-tax cost of equity basis. The use of a WACC or cost of equity in valuations is dependent on actual

leverageemployed.

SENSITIVITY ANALYSIS

Set out below are the initial indications of the key assumptions the Directors believe would have a material impact upon the fair value of the

investments should they change. In the absence of an operating business model for each underlying renewable energy asset, the sensitivities

have been conducted on the acquisition models of these assets. The following sensitivities 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 Directors consider the changes in inputs to be within a reasonable expected range based on their understanding of market transactions.

Thisis not intended to imply that the likelihood of change or that possible changes in value would be restricted to this range.

DISCOUNT RATE

The sensitivity demonstrates the impact of a change in the discount rate applied to the pre-tax, equity cash flows from all of the Company’s

renewable energy asset investments as at 31 December 2021. A range of +/- 0.5% has been considered to determine the resultant impact on

the Company’s NAV per share and the fair value of its solar asset investments. A sensitivity of +/-0.5% is considered reasonable given historic

Company discount rate changes and is inline with discount rate sensitivities utilised by the Company’s peers.

As at 31 December 2021, the weighted average discount rate range used was 6.3% (December 2020: 6.7%) on a WACC basis, and 7.8% (December

2020: 8.3%) on a pre-tax cost of equity basis. The use of a WACC or cost of equity in valuations is dependent on actual leverageemployed.

ELECTRICITY PRODUCTION

The Company’s solar asset investments are valued based upon a forecast P50 solar energy generation profile (being a 50% probability that this

generation estimate will be met or exceeded). A technical adviser has derived this generation estimate by taking into account a range of irradiation

datasets, satellite and ground-based measurements, and site-specific loss factors including module performance degradation, module mismatch

and inverter losses. These items are then considered in deriving the anticipated production of the individual solar asset (MWh per annum) based

upon a 50% probability of exceedance.

The sensitivity estimates the impact on the fair value of solar asset investments and NAV per share of a change of production estimates to P90

(90% likely probability of exceedance) and a P10 generation estimate (10% probability of exceedance).

101

US SOLAR FUND PLC Annual Report and Financial Statements

As P10 generation estimates were not independently obtained for each solar asset on or about the time of the asset acquisition, the Directors

have determined a proxy P10 estimate for those assets by assessing the relationship between the independently determined P50 and P90

generation estimates for each of the assets in the Operating Portfolio (e.g., a one-year P90 generation estimate might be 92.5% of a one-year P50

generation estimate, implying that it is 7.5% lower than the P50 generation estimate).

In determining the proxy P10 generation estimate, the Directors have assumed that the relationship between a P50 generation estimate and a

P10 generation estimate is the same as that between a P50 generation estimate and a P90 generation estimate in absolute terms. Therefore a

one-year P10 generation estimate by this methodology would be 107.5% (i.e. 100% + 7.5%) of the asset’s P50 generation estimate.

MERCHANT PERIOD ELECTRICITY PRICES

Each of the assets underlying the Company’s solar asset investments have long-term PPAs in place with creditworthy energy purchasers and

thus the PPA prices are not impacted by energy price changes during this period. For the post-PPA period of each solar asset, the Directors use

long-term electricity price forecasts that have been prepared by a market consultant in their determination of the fair value of the Company’s

operating solar asset investments. These forecasts from market consultants take into consideration climate change related factors when pricing

the electricity price forecasts. Further information is included in Section 4 – Environmental, Social and Governance, in the Company’s response to

recommendation 5 of the TCFD reporting framework.

The sensitivities show the impact of an increase / decrease in power prices for each year of the power price curve for each plant over the plant’s

remaining economic life after the conclusion of the existing PPAs. A flat 10% increase / decrease in market electricity prices from forecasted levels

over the remaining asset life of all plants have been used in the sensitivity analysis. A 10% increase / decrease has been used as merchant period

prices are determined upon the discretion of expert market consultants.

OPERATING EXPENSES

The operating costs of the assets underlying the Company’s solar asset investments include annual operations and maintenance (O&M), asset

management (AM), insurance expenses, land lease expenses, major maintenance and general administration expenses. Most operating expenses

for the Solar Power Assets are contracted for a defined period of up to 5 years and as such there is typically little variation in annual operating

costs. Provisions are also raised at the underlying project or SPV level of ongoing major maintenance/repairs and replacement parts throughout

the assets’ useful lives. However, there may be cases where all operating costs are recontracted at a 10% premium or discount.

The sensitivity above assumes a 10% increase/decrease in annual operating costs for all underlying assets and the resultant impact on the

Company’s fair value of investments and NAV per share.

OPERATING LIFE

The useful operating life of a solar asset is generally accepted by independent valuers to be the lesser of the lease term for asset site and

the independent engineer’s assessment of the asset’s useful life. The Investment Manager conducted a useful life analysis with a reputable

independent engineer in December 2021. As a result of the analysis, 30 of 42 assets within USF’s portfolio had their operating lives extended

to from 35 to 40 years from commencement of commercial operations. The Company’s maximum useful life assumption is 40 years (December

2020: 35 years) for newly constructed assets.

The sensitivity above assumes a three-year increase/decrease in useful operating life of the Company’s Solar Assets, and the resultant impact on

the Company’s fair value of investments and NAV per share.

TAX R ATE

The United States imposes a tax on profits of US resident corporations at a rate of 21%. The sensitivity above assumes the US corporate tax rate

increases / decreases by 5% (to 26% / 16%) and shows the resultant impact on the Company’s fair value of investments and NAV per share.

The Company has an authorised share capital of 500,000,000 ordinary shares.

102

US SOLAR FUND PLC Annual Report and Financial Statements

On incorporation the Company issued one ordinary share of $0.01 which was fully paid up.

Following a successful application to the High Court and lodgement of the Company’s statement of capital with the Registrar of Companies, the

Company was permitted to cancel its share premium account. This was effected on 21 June 2019 by a transfer of the balance of $194 million from

the share premium account to the capital reduction reserve. The capital reduction reserve is classed as a distributable reserve and dividends to be

paid by the Company are to be offset against this reserve.

In line with its target dividend, the Company declared a dividend of 1.5 cents per share, totalling $4,982,885 for the period ending 30

September 2021. This dividend was paid on 7 January 2022. This brought total dividends declared during the year ended 31 December 2021

to $14,288,657 (or 4.5 cents per share), of which $1,192,451 was from retained earnings and $13,096,206 was paid from the Capital Reduction

Reserve. The Company paid total cash dividends of $10,306,733 (or 3.5 cents per share) during the year. This comprises 0.5 cents per share (or

$1,000,962 per quarter) for 3Q 2020 (which the Board declared in 2020 and paid in 2021) and 4Q 2020 dividends, and 1.25 cents per share (or

$4,152,405 per quarter) for 1Q 2021 and 2Q 2021 dividends which were declared and paid in 2021.

19. RESERVES

The nature and purpose of each of the reserves included within equity at 31 December 2021 are as follows:

• Share premium reserve: represents the surplus of the gross proceeds of share issues over the nominal value of the shares, net of the direct

costs of equity issues and net of conversion amount. As at 31 December 2021 the share premium account has a balance of $128,035,864

(2020: $184,786).

• Capital reduction reserve: represents a distributable reserve (which may be utilised in respect of dividend payouts) created following a court

approved reduction in capital. As at 31 December 2021 the capital reduction reserve has a balance of $175,080,315 (2020: $188,176,521).

• Capital reserve: represents cumulative net gains and losses, of a capital nature, recognised in the Statement of Profit and Loss and Other

Comprehensive Income and associated tax allocations arising from the MSA fee income and interest distributions. As at 31 December 2021

the capital reserve reflects a profit of $12,648,250 (2020: $3,271,402).

• Retained earnings represent cumulative net gains and losses, of an income nature, recognised in the Statement of Profit and Loss and Other

Comprehensive Income and associated tax allocations arising from the MSA fee income and interest distributions. As at 31 December 2021,

retained earnings reflects a profit of $4,910,359 (2020: $524,715).

The only movements in these reserves during the year are disclosed in the statement of changes in equity.

20. NET ASSET VALUE PER SHARE

Basic NAV per share is calculated by dividing the Company’s net assets as shown in the statement of financial position that are attributable to

the ordinary equity holders of the Company by the number of ordinary shares outstanding at the end of the period. As there are no dilutive

instruments outstanding, basic and diluted NAV per share are identical.

21. CASH FLOW STATEMENT RECONCILIATION

IAS 7 Statement of Cash Flows require additional disclosures about changes in an entity’s financing liabilities, arising from both cash flow and non-

cash flow items. As at 31 December 2021 the Company has no financing liabilities and therefore no further disclosure is required.

22. TRANSACTIONS WITH RELATED PARTIES

The Company and the Directors are not aware of any person who, directly or indirectly, jointly or severally, exercises or could exercise control

over the Company. The Company does not have an ultimate controlling party.

Details of related parties are set out below:

end (2020: $nil).

103

US SOLAR FUND PLC Annual Report and Financial Statements

SUBSIDIARY

The Company previously issued loans totalling $43 million to its subsidiary USF Holding Corp. The principal portions of the loans are repayable in

7 years from issuance. The loans bear interest at rates of 5% and 4.1% respectively, payable semi-annually in arrears.

INVESTMENT MANAGER

The Investment Manager is entitled to management fees under the terms of the Investment Management Agreement. The Company shall pay

to the Investment Manager an annual fee (exclusive of value added tax, which shall be added where applicable) payable quarterly in arrears

calculated at the rate of:

ASSETS UNDER MANAGEMENT

FEE BASED ON NAV

< $500million 1.0% per annum

$500million to $1billion 0.9% per annum

> $1billion 0.8% per annum

Based on the Net Asset Value on the last Business Day of the relevant quarter.

The Management Fee due in respect of each quarter shall be invoiced by the Manager to the Company as at the final Business Day of the relevant

quarter, and shall be due and payable in the following manner:

a) no later than 10 Business Days after the Payment Date, 90% of the Management Fee shall be paid to the Manager in cash to such bank

account as the Manager may nominate for this purpose; and

b) 10% of the Management Fee shall be paid to the Manager or an Associate (as directed by the Manager) in the form of ordinary shares in

accordance with the provisions stated in the Investment Management Agreement.

For the avoidance of doubt, where there are C Shares

in issue, the advisory fee will be charged on the Net Asset Value attributable to the

ordinary shares and C Shares respectively. On 10 November 2020, the Board approved a recommendation from the Investment Manager to have

the Administrator arrange for 10% of its Management Fee to be applied to purchase ordinary USF shares in the secondary market. From that

time, the Company ceased issuing shares to the Investment Manager.

A management fee of $2,880,537 (2020: $1,939,925) was incurred during the year ($193,992 paid or payable in ordinary shares), of which

$1,617,740 (2020: $538,018) remained payable at 31 December 2021 ($97,556 payable in ordinary shares). In addition to the management fee,

the Manager shall also be entitled to payment of the following:

a) a fee for any successful arrangement of debt services payable at a rate of 0.5% of the debt face value; and

b) a fee for any oversight of asset construction services payable at market rates, negotiated on an arms’ length basis and subject to the approval

of the Board.

The Manager provides debt arranging services to the Fund, including contacting and liaising with capital providers, negotiating borrowing terms,

obtaining credit ratings, implementing interest rate hedging strategies and executing documentation. The Manager was successful in securing

debt, interest rate hedging and letter of credit facilities at competitive terms for the Fund, providing diversification to the Fund’s capital sources.

For this service, the Manager receives debt arranging fees of 0.5% of the face value of new third-party debt and letter of credit facilities.

Debt arrangement fees totalling $381,236 were incurred and paid during the year (2020: $336,500). Asset management and construction

services fees totalling $476,277 ($459,393 accrued; $16,884 paid by underlying solar assets) were incurred during the year (2020: $360,061).

23. CAPITAL COMMITMENTS

Other than as disclosed in the post balance date events note, the Company had no contingencies and no other significant capital commitments at

the reporting date.

24. POST BALANCE DATE EVENTS

On 10 February 2022, USF announced it would exercise the Company’s $21 million option on a second 25% tranche of the 200MW

California

project MS2. This will bring USF’s ownership of the project to 50% and 100MW

On 24 March 2022, the Company announced a dividend of 1.5 cents per Ordinary Share for the period ending 31 December 2021.

There were no other events after balance date which requires disclosure.
