CHAIRMAN’S STATEMENT

INTRODUCTION AND RESULTS

I am pleased to present this interim report for the six months ended 30 September 2022 and my first report to you since being appointed Chairman on 19 July 2022. I would like to thank my predecessor, Andrew Joy, for his excellent stewardship of the Company during his time as Chairman.

After a very difficult year to 31 March 2022, during which the Company’s Net Asset Value (“NAV”) fell substantially and underperformed the NASDAQ Biotechnology Index (the “Benchmark”), I am pleased to report that the first six months of this year have seen the Company regain some lost ground; the NAV per share total return^ was 9.6%, outperforming the rise of 6.8% in the Benchmark.

A number of factors contributed to this improvement in performance, including increased levels of merger and acquisition (“M&A”) activity and an improved regulatory and political backdrop in the USA. A fuller description of performance in the period is set out in the Portfolio Manager’s Review.

The Company’s NAV also benefited from the depreciation in sterling over the period by 15.2% against the U.S. dollar, being the currency in which the majority of the Company’s investments are denominated.

In addition, the presence of gearing^ over the period contributed 0.6% to the Company’s NAV performance. While gearing was reduced from 8.4% to 6.6% over the period and the Portfolio Manager aims to keep gearing in the 5-10% range, they anticipate that gearing will be at the upper end of that range in the future.

The Company has maintained some exposure to “crossover” investments (investments in a Company’s last private funding round prior to an initial public offering (“IPO”)) and to Chinese biotech. Investments in China represented 10.3% of the portfolio as at the period end. Despite satisfactory underlying performance, the value of these investments fell as a result of investors’ concerns about China. The Portfolio Manager continues to believe in the high levels of innovation found in the biotechnology sector in China, but the difficult local macroeconomic and regulatory environments are proving to be a deterrent to further investment.

SHARE PRICE PERFORMANCE

The outperformance of the NAV was enhanced at the share price level, driven by a narrowing in the discount^ of the share price to the NAV per share. At 31 March 2022, the discount of the share price to the NAV per share was 6.2% and at 30 September, 5.3%. When combined with the increase in NAV, this reduction in the discount contributed to a share price return^ over the six months of 10.7%.

DISCOUNT AND PREMIUM MANAGEMENT

The Company’s shares continued to trade at a discount to the net asset value per share throughout the period. Shareholders will be aware that the Company pursues an active discount management policy, buying back shares when the discount of the Company’s share price to the NAV per share is higher than 6%. Accordingly, during the period the Company bought back 1,076,286 shares, at an average discount of 8.2% to the NAV per share, at a cost of £10.5 million.

At the period end there were 40,082,396 shares in issue and, as previously mentioned, the share price traded at a 5.3% discount to the NAV per share. As we have previously commented, it remains possible for the share price discount to trade at a discount wider than 6% for a period of days or indeed longer, particularly in volatile markets. However, the Company remains committed to protecting a 6% share price discount over the longer term. Since the period end a further 61,982 shares have been bought back for cancellation and at the time of writing the share price discount stands at 5.7%.

PERFORMANCE FEE

At the year end, we reported that there was no provision within the Company’s NAV for any performance fee payable at a future calculation date. That is still the case as at the half year end.

As explained in more detail in the Annual Report, the performance fee is calculated quarterly and is dependent on the long-term outperformance of the Company. In addition, a performance fee only becomes payable to the extent that the cumulative outperformance gives rise to a total fee greater than the total of all performance fees paid to date.

OUTLOOK

While current macroeconomic conditions remain extremely challenging, there are a number of potential catalysts for a return to a more positive environment. These include the increase in M&A activity, an improved political environment, and a more benign regulatory environment in the U.S. Most importantly, in the biotechnology sector itself, the industry pipeline is growing and the sector continues to offer compelling innovation based on exciting new drug technologies.

The Board shares the Portfolio Manager’s optimism for the long term. While the current market backdrop may present some headwinds, the Board believes that over the longer term the attractions of the sector and the positioning of the portfolio will generate attractive absolute and relative returns for investors.

PORTFOLIO MANAGER’S REVIEW

GEOFF HSU

Performance

The Company’s NAV per share increased by 9.6% during the six-month period ended 30 September 2022. This compares with a 6.8% increase in the NASDAQ Biotechnology (the “Benchmark” or the “NBI”), measured on a sterling adjusted basis. The devaluation of the pound versus the U.S. dollar contributed approximately 15% of positive NAV performance over the period.

After a difficult fiscal year for the Company, ending 31 March 2022, weakness in the biotech sector continued in April and May, principally driven by macroeconomic factors rather than biotech fundamentals. Investor concerns over rising interest rates, rising inflation, and the risk of a recession resulted in a steep correction in share prices for unprofitable technology stocks broadly, including emerging biotech. Valuations for emerging biotech, which had already been driven to 20-year lows, sank even further at the start of the six-month period but appeared to bottom out in May and June. In August, drug pricing legislation in the U.S. was passed as part of the Democrats’ “Inflation Reduction Act”. While the bill allows for limited drug price negotiation by Medicare starting in 2026, the provisions appear manageable for the industry and passage of the bill clears a longstanding political overhang for the sector. By the end of September, the biotech sector had begun staging a recovery from depressed levels.

The Company’s outperformance versus the Benchmark during the review period was primarily due to outperformance of the emerging biotech positions in the portfolio.

We have chosen to maintain our strategic tilt towards the smaller emerging companies in the biotech sector over the larger profitable companies because most of the innovation in biotech is occurring in the emerging segment of the industry. As shown in Figure 1 on page 5 of the Half Year Report, as of 31 March 2021, the beginning of the prior fiscal year, the Company was significantly overweight small cap biotech stocks (those with a market capitalization under U.S.$2 billion) and significantly underweight large cap biotech (those with a market capitalization above U.S.$10 billion) relative to the Benchmark. Given the significant underperformance of small cap biotech versus large cap biotech of approximately 30%, the Company’s small cap bias has acted as a significant headwind to the Company’s relative performance for the past 18 months. Notably, as of 30 September 2022, the divergence between small and large cap biotech performance had not yet converged. Our view is that a relative performance recovery of the small cap names is long overdue given that their absolute valuations have declined to historical lows.

We have therefore kept our overweight positioning in small caps and underweight positioning in large caps because we believe the small cap stocks have the most upside potential in the near term.

Our confidence in a small cap biotech recovery is based on two observations. The first observation is shown in Figure 2 on page 6 of the Half Year Report, which plots the relative performance of the XBI – an equal weighted biotech index created in 2006 which is commonly used as a proxy for small and mid cap biotech performance - against the S&P 500 Index. Since the XBI’s inception, one can see that it has generally outperformed the S&P 500 over the past 15 years, indicating that emerging biotech has generally been a good place to invest over the long term. Over the course of that multi-year outperformance, there have been temporary periods of relative underperformance, denoted by the red circles in the graph, when the XBI has underperformed the S&P 500. What is so striking about the most recent biotech drawdown is how unusual it is in historical context. The most recent drawdown is the largest absolute fall of the XBI since its inception and the longest and most severe relative drawdown the XBI versus the S&P 500. Historically, each relative performance drawdown of the XBI versus the S&P 500 has been followed by a strong period of relative outperformance of the XBI (shown by the green arrows), ranging from 68-109%. Notably, all previous relative performance drawdowns have seen a subsequent recovery to a new relative performance high. Our expectation is that a relative performance recovery from the low of the most recent drawdown is likely to occur in the near term. Indeed, if one looks at the rightmost portion of the graph, it does appear we are in the early stages of such a recovery.

The second observation giving us confidence in a small cap biotech recovery is the fact that absolute valuations for the emerging biotech segment are so depressed. One objective way of valuing unprofitable biotech is to simply compare the market caps of these companies with the net cash on their balance sheets. If one looks at the median ratio of market cap to net cash for the biotech industry (shown in Figure 3 on page 7 of the Half Year Report), one observes that the current drawdown has driven sector valuations to levels we have not seen in over 20 years. Valuations on this metric are now below those found after the Dot Com Bust, the Great Financial Crisis, and the Hillary Clinton drug pricing tweet in 2015. This translates into over 25% of biotech companies (over 150 companies) that are now trading at market caps below the net cash on their balance sheets. We do not believe these unprecedented valuation levels are warranted given the fundamentals of the industry.

One of the principal factors that has clearly driven overall market weakness – and weakness in unprofitable technology companies in particular – is the rapid rise of interest rates in the U.S. over the past several months. In order to combat rising inflation, the U.S. Federal Reserve (the “Fed”) has been aggressively increasing interest rates. By increasing the risk-free rate, these interest rate hikes increase the discount rate investors use to value biotech companies and reduce their discounted cash flow value. Importantly, because most biotech companies are not heavily dependent on debt financing, an increase in short-term rates has very little impact on their businesses. The impact on biotech really stems from any increase in the long end of the yield curve increasing the discount rate. Figure 5 (on page 9 of the Half Year Report) shows that as of 30 September 2022, the U.S. 10-year government yield had risen to approximately 4%. Importantly, this rate already incorporates expectations for continued Fed rate hikes in the near term through the middle of 2023, followed by rate reductions once inflation is brought under control. We would therefore argue that many of the near-term rate hikes are already priced into market expectations and should not substantially impact the 10-year rate. Given that absolute valuations for emerging biotech are already at 20-year lows, we would not anticipate that further interest rate increases will significantly further depress valuations.

Many economists are now forecasting a recession in 2023. Healthcare has generally been a defensive sector during recessions, and we would argue that biotech as a secular growth sector should be less impacted by an economic downturn compared to other industries. Patient demand for drugs should not be dramatically affected if the U.S. enters a recession.

With regards to inflation, pricing power in the drug industry has traditionally been strong. We believe most companies will be able to push through annual price increases on their drug sales at least on par with inflation in order to maintain margins and offset any inflationary pressure on costs.

The China portion of the portfolio was also under pressure during the review period for entirely different macro reasons. Investor concerns over a slowing Chinese economy, China’s zero COVID policy, rising U.S.-China tensions, and geopolitical fears over a potential invasion of Taiwan by China led to a significant decline in Chinese securities generally during the review period. The Hang Seng Index, a broad market index tracking Hong Kong listed stocks, declined over 21% in local currency terms during the review period and sat at a 10-year low as of the end of the September. While we continue to believe in the long-term prospects for Chinese biotech and the Chinese government’s unwavering commitment to promoting innovation in the sector, we have elected to reduce our Chinese public equity exposure and shift that capital to U.S. emerging biotech. This is a tactical shift driven by our expectation that a recovery in U.S. emerging biotech is likely to occur sooner than a recovery in Chinese biotech.

Contributors to Performance

The principal contributors to performance during the review period were Syndax Pharmaceuticals, Mersana Therapeutics, Forma Therapeutics, Sarepta Therapeutics, and Global Blood Therapeutics.

•        Syndax Pharmaceuticals is a clinical stage oncology company developing two drugs, one for acute myeloid leukemia and one for chronic graft versus host disease. Both programs will have pivotal data readouts in the second quarter of 2023. The company’s share price rose during the review period in anticipation of those data releases.

•        Mersana Therapeutics is a clinical stage company developing antibody-drug conjugate therapeutics. The company’s lead asset, UpRi is in a pivotal program in late-stage ovarian cancer that will have data in mid-2023. The stock appreciated during the review period after the company signed an option license with GlaxoSmithKline for the co-development of one of Mersana’s earlier stage assets. As part of the deal, Mersana received a $100 million upfront payment from GSK, resulting in a re-rating of the stock.

•        Forma Therapeutics is a development stage biopharmaceutical company focused on developing drugs to treat nonmalignant hematological disorders. The company’s lead drug is being developed for the treatment of sickle cell disease. In early September, Novo Nordisk announced that it was acquiring Forma for $1.1 billion in cash, representing a 49% premium to Forma’s closing price the previous day.

•        Sarepta Therapeutics is a commercial biotechnology company focused on rare neuromuscular diseases. It markets three approved therapies for Duchenne muscular dystrophy but is also developing a gene therapy for the condition. The company’s share price rose on the increased investor expectation that the company would be able to obtain accelerated approval for the gene therapy in 2023.

•        Global Blood Therapeutics is a commercial stage biopharmaceutical company focused on developing drugs to treat sickle cell disease. In early August, Pfizer announced that it was acquiring Global Blood for $5.4 billion in cash, representing over a 100% premium to the company’s share price prior to rumours of a potential deal.

Detractors from Performance

The principal detractors from performance were Horizon Therapeutics, Jounce Therapeutics, Guardant Health, Mirati Therapeutics, and GH Research.

•        Horizon Therapeutics is a specialty pharmaceutical company that launched Tepezza, a treatment for thyroid eye disease, in the U.S. in early 2020. Tepezza sales declined sharply in 2022 due to a combination of market saturation, stricter payor coverage, and the COVID Omicron wave. As a result, investor expectations for long-term Tepezza sales declined, sending the stock lower.

•        Jounce Therapeutics develops immunotherapy drugs for the treatment of cancer. Shares of the company declined after it disclosed that a Phase 2 study in lung cancer for one of its drugs failed to meet its primary endpoint.

•        Guardant Health is a genomics company developing liquid biopsy tests for detecting and monitoring cancers. Shares of the company were under pressure during the review period due to the difficult macro environment as well as a delay in the clinical trial data release for the company’s blood-based screening test to detect colorectal cancer.

•        Mirati Therapeutics is a clinical-stage biopharmaceutical company focused on the discovery and development of novel targeted oncology treatments. Shares underperformed amid market weakness and mixed clinical results from their lead program in second-line lung cancer.

•        GH Research is developing a psychedelic drug for treatment-resistant depression. The stock fell due to overall biotech sector weakness during the review period.

IPO Market has Slowed Considerably

Unsurprisingly, the drawdown in the general markets has resulted in a dramatic decline in the number of IPOs, as shown in Figure 6 on page 11 of the Half Year Report. Due to market conditions, none of the Company’s crossover positions went public during the review period. We have also stopped making new crossover investments until the IPO market recovers. The portfolio now includes only three crossover investments, all of which are Chinese companies. Our current expectation is that all of them will go public by mid-2023. Despite the decline in IPO activity, most quality biotech companies that are already public have not had much difficulty in raising capital, so there remains ample investor appetite for funding biotech. Given the lower valuations of biotech generally, we have looked to capitalize on opportunities to finance quality companies at these new lower prices.

Passage of Drug Pricing Legislation Clears Political Overhang

In August, the Democrats’ “Inflation Reduction Act” was signed into law in the U.S. The law includes a number of drug pricing provisions to help pay for the climate and energy provisions of the legislation. There are three elements of the drug pricing reform: 1) a redesign of Medicare Part D to cap out-of-pocket costs that seniors pay for prescription drugs (a positive for the industry); 2) an inflation cap on annual drug price increases; and 3) the ability for the federal government to negotiate Medicare drug prices for a limited number of drugs starting in 2026. We don’t think the bill will have an impact on biotech in the near term and will generally be manageable for the drug industry overall. The spectre of drug pricing legislation has been an overhang and risk for the biotech sector for decades. Now that this legislation has passed, we believe it is a clearing event for the sector that will allow the sector to re-rate. We do not expect Congress to revisit the issue for the next several years. On 8 November 2022, midterm Congressional elections took place in the U.S., but as of 14 November, the results of those elections had not been completely determined.  The Democrats were able to maintain their slight majority in the Senate, with Republicans still appearing likely to win a small majority in the House.  If Republicans gain control of the House, the prospects of any additional drug pricing legislation are even less likely.

M&A Activity Expected to Accelerate

We anticipated that M&A activity in the biotech sector would increase with the recent drawdown in valuations. Development-stage biotech companies that can complete equity financings at healthy prices can remain independent entities to generate additional value and are not forced to sell themselves to a larger player if the acquisition price is deemed insufficient. Now that stock prices are quite a bit lower, biotech companies face the unattractive prospect of financing their programs with much more dilutive equity offerings than they previously contemplated, making a sale to a strategic acquiror a more palatable alternative than it was under healthier market conditions. At the same time, the urgency for large pharma to acquire smaller biotech companies remains elevated. Numerous large pharma companies like Merck, Bristol-Myers Squibb, and AbbVie are facing key patent expirations on multi-billion-dollar blockbuster products in the 2025-2030 timeframe. These companies are highly motivated to acquire innovative biotech products that can help them replace expected revenue losses in the latter half of this decade. The current market environment should therefore be conducive to accelerated M&A activity. Figure 7 (on page 12 of the Half Year Report) shows announced M&A transactions involving public biotech targets each quarter since the beginning of 2018. While there is always natural variability year to year in M&A volume, it is encouraging that the number of announced transactions has increased sequentially in the second and third calendar quarters of 2022, suggestive of a pickup in M&A activity.

The Company benefited directly from two transactions during the review period: Novo Nordisk’s acquisition of Forma Therapeutics for $1.1 billion and Pfizer’s acquisition of Global Blood Therapeutics for $5.4 billion. There are many other companies in the portfolio that we believe would make attractive M&A candidates, and we are optimistic that some of them will be acquired as well in the months ahead.

Outlook

With valuations in emerging biotech at 20-year lows and a drawdown in small and mid-cap biotech that has been the worst in over 15 years, we have never seen such a compelling entry point for long-term investors to invest in biotech. We expect the sector to resume its historical outperformance versus the general market over the next several years. Importantly, the fundamentals of the industry remain strong. The industry pipeline continues to grow, with robust innovation based on new drug development technologies like gene therapy, cell therapy, and RNA-based therapies still in the early stages of reaching their full potential. The regulatory environment at the FDA remains constructive towards the approval of new drugs, especially in areas of unmet medical need. There are signs that M&A activity is accelerating, as large pharma companies facing upcoming patent expirations on key products aggressively look to acquire innovative biotech companies now trading at inexpensive valuations. Finally, the political overhang of drug pricing reform has now been cleared with the passage of the Inflation Reduction Act, which we expect to have minimal impact on biotech. Indeed, we have never seen such a dramatic disconnect between industry fundamentals and share price performance in the sector. While rising interest rates will continue to be a headwind for the stock market generally, any indication of inflation moderation could have a favorable impact on future interest rate expectations. The portfolio will continue its overweight bias in small cap emerging biotech versus the Benchmark, as we believe this positioning will deliver the best returns for investors when the long overdue recovery occurs. Gearing will remain in the 5-10% range, though given the historically depressed valuations, investors should expect gearing at the upper end of the range. Although the market may continue to be challenging in the short term, the compelling valuations in biotech give us optimism that a recovery in the sector will eventually occur in due course.

NOTES TO THE FINANCIAL STATEMENTS

1.A) GENERAL INFORMATION

The Biotech Growth Trust PLC is a company incorporated and registered in England and Wales. The Company operates as an investment company within the meaning of Section 833 of the Companies Act 2006 and has made a successful application under Regulation 5 of the Investment Trust (Approved Company) (Tax) Regulations 2011 for investment trust status to apply to all accounting periods commencing on or after 1 April 2012.

1.B) BASIS OF PREPARATION

The Company’s condensed financial statements for the six months ended 30 September 2022 have been prepared in accordance with IAS 34 “Interim Financial Reporting”. They do not include all the financial information required for the full annual financial statements and have been prepared using accounting policies adopted in the audited financial statements for the year ended 31 March 2022. Those financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”).

The Directors have sought to prepare the financial statements in compliance with presentational guidance set out in the Statement of Recommended Practice (the “SORP”) for Investment Trust Companies and Venture Capital Trusts produced by the Association of Investment Companies (“AIC”), dated July 2022.

The Company’s financial statements are presented in sterling and all values are rounded to the nearest thousand pounds (£’000) except when otherwise indicated.

The financial statements have not been audited by the Company’s auditors.

1.C) SEGMENTAL REPORTING

IFRS 8 requires entities to define operating segments and segment performance in the financial statements based on information used by the Board of Directors. The Directors are of the opinion that the Company is engaged in a single segment of business, being investment business.

1.D) GOING CONCERN

The Directors believe that it is appropriate to adopt the going concern basis in preparing the financial statements as the assets of the Company consist mainly of securities that are readily realisable and, accordingly, the Company has adequate financial resources to continue in operational existence for at least 12 months from the date of the approval of the financial statements. The next continuation vote of the Company will be held at the Annual General Meeting in 2025 and further opportunities to vote on the continuation of the Company will be given to shareholders every five years thereafter.

5. NET ASSET VALUE PER SHARE

The net asset value per share is based on the net assets attributable to equity shareholders of £420,734,000 (31 March 2022: £394,208,000) and on 40,082,396 shares (31 March 2022: 41,158,682) being the number of shares in issue at the period end.

6. TRANSACTION COSTS

Purchase and sale transaction costs for the six months ended 30 September 2022 amounted to £912,000 (six months ended 30 September 2021: £517,000); broken down as follows: purchase transactions for the six months ended 30 September 2022 amounted to £411,000 (six months ended 30 September 2021: £201,000). Sale transactions amounted to £501,000 (six months ended 30 September 2021: £316,000). These costs comprise mainly commission.

7. INVESTMENTS

IFRS 13 requires the Company to classify fair value measurements using the fair value hierarchy that reflects the significance of the inputs used in making the measurements. The fair value hierarchy consists of the following three levels:

•        Level 1 – quoted prices (unadjusted) in active markets for identical assets or liabilities;

•        Level 2 – inputs other than quoted prices included with Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

•        Level 3 – inputs for the asset or liability that are not based on observable market data (unobservable inputs).

At 30 September 2022 the investments in OrbiMed Asia Partners LP Fund (the LP Fund), XtalPi, StemiRNA and Yisheng Biopharma have been classified as Level 3 (see Level 3 reconciliation below).

The LP Fund is valued quarterly by OrbiMed Advisors LLC and is audited annually by KPMG LLP. As the 30 September 2022 valuation is not yet available, the LP Fund has been valued at its net asset value as at 30 June 2022. It is believed that the value of the LP Fund as at 30 September 2022 will not be materially different. If the value of the LP Fund were to increase or decrease by 10%, while other variables had remained constant, the return and net assets attributable to shareholders for the period ended 30 September 2022 would have increased or decreased by £205,000 (year ended 31 March 2022: £209,000).

The following investments have been valued by the Board following recommendations made by the Valuation Committee which has reviewed in detail both the valuations and the methodologies provided by Kroll, an independent valuer.

StemiRNA, XtalPi and Yisheng Biopharma have been valued using the probability-weighted expected returns methodology and are classified as Level 3. If the value of these investments were to increase or decrease by 10%, while all other variables remain constant, the return attributable to shareholders for the period ended 30 September 2022 would have increased or decreased by £3,664,000 (year ended 31 March 2022: £3,218,000).

Awakn Life Sciences warrants have been classified as Level 2 at the period end. If the value of the warrants were to increase or decrease by 10%, the return and net assets attributable to shareholders would have increased or decreased by £1,500.

The table overleaf sets out fair value measurements of financial assets in accordance with the IFRS13 fair value hierarchy system:

8. PRINCIPAL RISKS PROFILE

The principal risks which the Company faces from its financial instruments are:

i)        market price risk, including currency risk, interest rate risk and other price risk;

ii)       liquidity risk; and

iii)      credit risk.

Market price risk – This is the risk that the fair value or future cash flows of a financial instrument held by the Company may fluctuate because of changes in market prices. This market risk comprises three elements – currency risk, interest rate risk and other price risk.

Liquidity risk – This is the risk that the Company will encounter difficulty in meeting obligations associated with financial liabilities.

Credit risk – This is the risk that the counterparty to a transaction fails to discharge its obligations under that transaction, which could result in the Company suffering a loss.

Details of the Company’s management of these risks can be found in note 14 in the Company’s 2022 Annual Report.

There have been no changes to the management of or the exposure to these risks since the date of the Annual Report.

9. RELATED PARTY TRANSACTIONS

There have been no changes to the related party arrangements or transactions as reported in the Annual Report for the year ended 31 March 2022.

10. CREDIT RISK

J.P. Morgan Securities LLC (J.P. Morgan) may take assets with a value of up to 140% of the Company’s loan facility as collateral. Such assets held by J.P. Morgan are available for rehypothecation*.

* See Glossary.

As at 30 September 2022, the maximum value of assets available for rehypothecation was £35.6 million being 140% of the loan balance (£25.5 million) (31 March 2022: £44.4 million).

11. COMPARATIVE INFORMATION

The financial information contained in this half year report does not constitute statutory accounts as defined in sections 434 to 436 of the Companies Act 2006. The financial information for the six months ended 30 September 2022 and 2021 has not been audited by the Company’s auditor.

The information for the year ended 31 March 2022 has been extracted from the latest published audited financial statements. The audited financial statements for the year ended 31 March 2022 have been filed with the Registrar of the Companies. The report of the Company’s auditor on those accounts was unqualified, did not include a reference to any matters to which the Company’s auditor drew attention by way of emphasis without qualifying the report and did not contain statements under section 498(2) or 498(3) of the Companies Act 2006.

INTERIM MANAGEMENT REPORT

PRINCIPAL RISKS AND UNCERTAINTIES

A review of the half year, including reference to the risks and uncertainties that existed during the period and the outlook for the Company can be found in the Chairman’s Statement and in the Portfolio Manager’s Review. The principal risks faced by the Company fall into the following broad categories: objective and strategy; share price volatility and the level of discount/premium; portfolio performance; portfolio management key person risk; operational and regulatory risk (including cyber risk); market price risk; valuation risk; climate change; liquidity risk; shareholder profile; currency risk; the risk associated with the Company’s loan facility; and credit risk. Information on each of these areas is given in the Strategic Report/ Business Review within the Annual Report for the year ended 31 March 2022. The Company’s principal risks and uncertainties have not changed materially since the date of that report and are not expected to change materially for the remaining six months of the Company’s financial year, although Russia’s invasion of Ukraine and the ensuing war, together with increasing tensions between the West and China, have brought the geopolitical aspect of market risk into greater focus.

The Board, the AIFM and the Portfolio Manager discuss and identify emerging risks as part of the risk identification process and have considered, amongst other things, the potential effects of the economic slowdown in China and ongoing global supply chain disruption on the Company’s performance.

RELATED PARTY TRANSACTIONS

During the first six months of the current financial year, no transactions with related parties have taken place which have materially affected the financial position or the performance of the Company.

GOING CONCERN

The Directors believe, having considered the Company’s investment objective, risk management policies, capital management policies and procedures, the nature of the portfolio and expenditure projections, that the Company has adequate resources, an appropriate financial structure and suitable management arrangements in place to continue in operational existence for the foreseeable future and, more specifically, that there are no material uncertainties relating to the Company that would prevent its ability to continue in such operational existence for at least twelve months from the date of the approval of this half yearly financial report. For these reasons, they consider there is reasonable evidence to continue to adopt the going concern basis in preparing the financial statements.

DIRECTORS’ RESPONSIBILITIES

The Board of Directors confirms that, to the best of its knowledge:

(i)       the condensed set of financial statements contained within the Half Year Report have been prepared in accordance with applicable International Accounting Standards (IAS) 34; and

(ii)      the interim management report includes a true and fair review of the information required by:

(a)     DTR 4.2.7R of the Disclosure Guidance and Transparency Rules, being an indication of important events that have occurred during the first six months of the financial year and their impact on the condensed set of financial statements; and a description of the principal risks and uncertainties for the remaining six months of the year; and

(b)     DTR 4.2.8R of the Disclosure Guidance and Transparency Rules, being related party transactions that have taken place in the first six months of the current financial year and that have materially affected the financial position or performance of the entity during that period; and any changes in the related party transactions described in the last annual report that could do so.

The Half Year Report has not been audited by the Company’s auditors.

This Half Year Report contains certain forward-looking statements. These statements are made by the Directors in good faith based on the information available to them up to the date of this report and such statements should be treated with caution due to the inherent uncertainties, including both economic and business risk factors, underlying any such forward-looking information.

GLOSSARY OF TERMS AND ALTERNATIVE PERFORMANCE MEASURES

AIC

Association of Investment Companies.

ALTERNATIVE INVESTMENT FUND MANAGERS DIRECTIVE (“AIFMD”)

Agreed by the European Parliament and the Council of the European Union and transposed into UK legislation, the AIFMD classifies certain investment vehicles, including investment companies, as Alternative Investment Funds (“AIFs”) and requires them to appoint an Alternative Investment Fund Manager (“AIFM”) and depositary to manage and oversee the operations of the investment vehicle. The Board of the Company retains responsibility for strategy, operations and compliance and the Directors retain a fiduciary duty to shareholders.

ALTERNATIVE PERFORMANCE MEASURE (“APMs”)

An APM is a numerical measure of the Company’s current, historical or future financial performance, financial position or cash flows, other than a financial measure defined or specified in the applicable financial framework. In selecting these APMs, the Directors considered the key objectives and expectations of typical investors in an investment trust such as the Company. Definitions of the terms used and the basis of calculation are set out in this Glossary and the APMs are indicated with a caret (^).

ACTIVE SHARE

Active Share is expressed as a percentage and shows the extent to which a fund’s holdings and their weightings differ from those of the fund’s benchmark index. A fund that closely tracks its index might have a low Active Share of less than 20% and be considered passive, while a fund with an Active Share of 60% or higher is generally considered to be actively managed.

CROSSOVER INVESTMENTS

Investments in a company’s last private round prior to an initial public offering (“IPO”).

DISCOUNT OR PREMIUM^

A description of the difference between the share price and the net asset value per share. The size of the discount or premium is calculated by subtracting the share price from the net asset value per share and is usually expressed as a percentage (%) of the net asset value per share. If the share price is higher than the net asset value per share the result is a premium. If the share price is lower than the net asset value per share, the shares are trading at a discount.

DRAWDOWN

A measure of downside volatility, a drawdown refers to how much an investment or sector is down from the peak before it recovers back to the peak.

GEARING^

Gearing represents prior charges, adjusted for net current liabilities, expressed as a percentage of net assets. Prior charges includes all loans for investment purposes.

Gearing 3 6.6% 8.4%

NET ASSET VALUE (“NAV”)

The value of the Company’s assets, principally investments made in other companies and cash being held, minus any liabilities. The NAV is also described as ‘shareholders’ funds’. The NAV is often expressed in pence per share after being divided by the number of shares which are in issue at the relevant date. The NAV per share is unlikely to be the same as the share price which is the price at which the Company’s shares can be bought or sold by an investor. The share price is determined by the relationship between the demand and supply of the shares in the secondary market.

NAV PER SHARE TOTAL RETURN^

The NAV per share total return for the period ended 30 September 2022 is calculated by taking the percentage movement from the NAV per share as at 31 March 2022 of 957.8p (31 March 2021: 1,446.4p) to the NAV at 30 September 2022 of 1,049.7p (30 September 2021: 1,327.0p). The Company has not paid any dividends to shareholders during the period.

ONGOING CHARGES^

Ongoing charges are calculated by taking the Company’s annualised operating expenses expressed as a proportion of the average daily net asset value of the Company over the year.

The costs of buying and selling investments are excluded, as are interest costs, taxation, performance fees, cost of buying back or issuing ordinary shares and other non-recurring costs.

OTC EQUITY SWAPS

Over-the-Counter (“OTC”) refers to the process of how securities are traded via a broker - dealer network, as opposed to a centralised exchange.

An equity swap is an agreement where one party (counterparty) transfers the total return of an underlying equity position to the other party (swap holder) in exchange for a payment of the principal, and interest for financed swaps, at a set date. Total return includes dividend income and gains or losses from market movements. The exposure of the holder is the market value of the underlying equity position.

There are two main types of equity swaps:

•        Funded – where payment is made on acquisition. They are equivalent to holding the underlying equity position with the exception of additional counterparty risk and not possessing voting rights in the underlying; and

•        Financed – where payment is made on maturity. As there is no initial outlay, financed swaps increase exposure by the value of the underlying equity position with no initial increase in the investments value – there is therefore embedded leverage within a financed swap due to the deferral of payment to maturity.

REHYPOTHECATION

Rehypothecation is the practice by banks and brokers of using collateral posted as security for loans as regulated by the U.S. Securities Exchange Commission.

SHARE PRICE TOTAL RETURN^

The share price total return for the period ended 30 September 2022 is calculated by taking the percentage movement from the share price as at 31 March 2022 of 898.0p (31 March 2021: 1,426.0p) to the share price as at 30 September 2022 of 994.0p (31 September 2021: 1,206.0p). The Company has not paid any dividends to shareholders during the period.
