While performance this year has been disappointing, our
Portfolio Manager expects that the overweighting of small
and mid cap companies will deliver positive results to
shareholders. In particular, they expect that the divergence
in the valuations of large and small/mid cap companies
will close. In addition, they anticipate that we can expect to
see continued consolidation in the biotechnology industry,

gaps in their own portfolios and, in many cases, impending

OUTLOOK
The biotechnology sector has been a critical area of
innovation and growth in recent years with the rate of

effective treatments continuing apace. With a focus on
precision medicine, cell and gene therapy, digital health,
and rare diseases, small biotechnology companies are
at the forefront of this innovation. Additionally, advances
in technology, the availability of big data and the use of


including regulatory hurdles and uncertainty around
funding. Drug development will remain a long-term and
costly pursuit. The broader economic environment also
remains challenging: global economic growth has slowed,
the cost of capital has risen, and geopolitical instability and
ongoing supply chain disruptions continue to challenge the
post-pandemic recovery. More broadly, elevated energy
prices and surprisingly persistent inflation will continue to
impact business investment.
Although the impact of these factors will continue to

2) We expected an increase in M&A activity due to the
compelling valuations of smaller biotech targets.
3) Emerging biotech, rather than large cap biotech,
was still contributing about two-thirds of the total
biopharmaceutical industry pipeline. Fundamental
innovation was strong.
All of these elements of our investment thesis remain intact.

cap biotech does have some defensive qualities during a
recession, recent analysis from Goldman Sachs shows that
small and mid cap biotech (as reflected by the SPDR S&P
Biotech ETF or XBI) have also outperformed the S&P 500
during the last four recessions.

in 2006. About 50% of this index consists of small cap
names. If one plots the relative performance of the XBI
versus the S&P 500 (shown in Figure 4, below), one can
see that since inception, the XBI has outperformed the
S&P 500, indicating that emerging biotech has historically
been a sector offering better returns than the broader

agency received a similar number of new drug applications
in 2022 as the past few years, reflecting continued strong
innovation in the industry. We suspect many of those
applications will be approved in 2023.
Importantly, we do not believe the reduced number of
approvals in 2022 means the FDA has become less

DRUG PRICING REFORM CLEARS

THE BIOTECH GROWTH TRUST PLC Annual Report for the year ended 31 March 2023
STRATEGIC REPORT
26
BUSINESS REVIEW
The Strategic Report on pages 1 to 37
contains a review of the Company’s
business model and strategy, an
analysis of its performance during
the financial year and its future
developments, as well as details of the
principal risks and challenges it faces.
Its purpose is to inform shareholders in the Company and
help them to assess how the Directors have performed their
duty to promote the success of the Company. The Strategic
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.
Such statements should be treated with caution due to the
inherent uncertainties, including both economic and business
risk factors, underlying such forward-looking information.
BUSINESS MODEL
The Biotech Growth Trust PLC is an externally managed
investment trust and its shares are listed on the premium

the London Stock Exchange.
The purpose of the Company is to achieve long-term growth
in its shareholders' wealth by providing a vehicle for investors
to gain exposure to a portfolio of worldwide biotechnology
companies, through a single investment.
The Company’s strategy is to create value for shareholders
by addressing its investment objective.
As an externally managed investment trust, all of the
Company's day-to-day management and administrative
functions are outsourced to service providers. As a result, the
Company has no executive directors, employees or internal
operations.
The Company employs Frostrow Capital LLP (Frostrow) as
its Alternative Investment Fund Manager (AIFM), OrbiMed
Capital LLC (OrbiMed) as its Portfolio Manager, J.P. Morgan
Europe Limited as its Depositary and J.P. Morgan Securities
LLC as its Custodian and Prime Broker. Further details
about their appointments can be found in the Report of the
Directors on pages 48 and 49.
The Board is responsible for all aspects of the Company’s
affairs, including setting the parameters for and monitoring
the investment strategy as well as the review of investment
performance and policy.
The Company is an investment company within the meaning
of Section 833 of the Companies Act 2006 and has been
approved by HM Revenue & Customs as an investment trust
(for the purposes of Section 1158 of the Corporation Tax Act
2010). As a result, the Company is not liable for taxation on
capital gains. The Directors have no reason to believe that
approval will not continue to be retained. The Company is not
a close company for taxation purposes.
INVESTMENT OBJECTIVE AND POLICY
The Company seeks capital appreciation through investment
in the worldwide biotechnology industry.
In order to achieve its investment objective, the Company

securities in biotechnology companies on a worldwide basis.
In connection with the investment policy, the following
guidelines apply:
The Company will not invest more than 10%, in
aggregate, of the value of its gross assets in other
closed ended investment companies (including
investment trusts) listed on the London Stock Exchange,
except where the investment companies themselves
have stated investment policies to invest no more
than 15% of their gross assets in other closed ended
investment companies (including investment trusts)
listed on the London Stock Exchange.
The Company will not invest more than 15%, in
aggregate, of the value of its gross assets in other closed
ended investment companies (including investment
trusts) listed on the London Stock Exchange.
The Company will not invest more than 15% of the value
of its gross assets in any one individual stock at the
time of acquisition.
The Company will not invest more than 10% of the value
of its gross assets in unquoted investments at the time
of acquisition. This limit includes any investment in
private equity funds managed by the Portfolio Manager

The Company may invest or commit for investment
a maximum of U.S.$15 million, after the deduction of
proceeds of disposal and other returns of capital, in
private equity funds managed by the Portfolio Manager,

The Company’s borrowing policy is that borrowing
will not exceed 20% of the Company’s net assets. The
Company’s borrowing requirements are met through
the utilisation of a loan facility, repayable on demand
and provided by J.P. Morgan Securities LLC. This facility
can be drawn by the Portfolio Manager overseen by

The Company may be unable to invest directly in certain
countries. In these circumstances, the Company may
gain exposure to companies in such countries by
investing indirectly through swaps. Where the Company
invests in swaps, exposure to underlying assets will not
exceed 5% of the gross assets of the Company at the
time of entering into the contract.
In accordance with the requirements of the Financial Conduct
Authority, any material change to the investment policy will
only be made with the approval of shareholders by ordinary
resolution.
PROPOSED CHANGES TO THE INVESTMENT
POLICY
As explained in the Chairman’s Statement on page 3, the Board
is proposing some changes to the investment policy in order to

portfolio management. The proposed changes will:
Enable derivative instruments (other than equity swaps)
to be used to mitigate risk and/or enhance return
subject to an aggregate net exposure of 5% of the value
of the Company’s gross assets measured at the time of
the relevant transaction; and
Remove the current limit on equity swaps but impose
a limit on aggregate net counterparty exposure,
through a combination of derivatives and equity swap
transactions, of 12% of the value of the gross assets of
the Company at the time of the transaction.
Accordingly, an ordinary resolution to approve the amended
investment policy is included in the Notice of AGM, beginning
on page 101, and a blacklined statement of the investment
policy showing the proposed changes is set out on page 106.
The proposed amendments have been approved in principle
by the Financial Conduct Authority in accordance with the
requirements of the Listing Rules.
INVESTMENT STRATEGY
The implementation of the Investment Objective has been
delegated to OrbiMed by Frostrow (as AIFM) under the Board’s
and Frostrow’s supervision and guidance.
Details of OrbiMed’s investment strategy and approach are set
out in the Portfolio Manager’s Review on pages 9 to 25. While
performance is measured against the Benchmark, the Board
encourages OrbiMed to manage the portfolio without regard to
the Benchmark and its make-up.
While the Board’s strategy is to allow flexibility in managing the
investments, in order to manage investment risk it has imposed
various investment, gearing and derivative guidelines and limits,
within which Frostrow and OrbiMed are required to manage the
investments, as set out in the Investment Policy.
PERFORMANCE MEASUREMENT
The Board measures OrbiMed's performance against the
NASDAQ Biotechnology Index (sterling adjusted). The Board
also monitors the Company's performance against its peer
group.
DIVIDEND POLICY
The Company invests with the objective of achieving capital
growth and it is expected that dividends, if any, are likely to
be small. The Board intends only to pay dividends on the
Company’s shares to the extent required in order to maintain
the Company’s investment trust status.
No dividends were paid or declared during the year (2022:
None).

the following ways:
Engaging regularly with institutional investors, discretionary
wealth managers and a range of execution-only platforms:
Frostrow regularly meets with institutional investors,
discretionary wealth managers and execution-only
platform providers to discuss the Company’s strategy and
to understand any issues and concerns, covering both
investment and corporate governance matters;
Making Company information more accessible: Frostrow

groups within the investment community, holding periodic
investment seminars, commissioning and overseeing PR
output and managing the Company’s website and wider
digital offering, including Portfolio Manager videos and
social media;
Disseminating key Company information: Frostrow
performs the Investor Relations function on behalf of the
Company and manages the investor database. Frostrow

factsheets, annual and half yearly reports and updates from
OrbiMed on the portfolio and market developments; and
Monitoring market activity, acting as a link between the
Company, shareholders and other stakeholders: Frostrow
maintains regular contact with sector broker analysts and
other research and data providers, and conducts periodic
investor perception surveys, liaising with the Board to
provide up-to-date and accurate information on the latest
shareholder and market developments.
KEY PERFORMANCE INDICATORS (KPIs)
The Board assesses the Company’s performance in
meeting its objective against the following key performance
indicators:
net asset value total return;
share price total return;
share price discount to net asset value per share; and
ongoing charges.
Information on the Company’s performance is provided
in the Chairman’s Statement and the Portfolio Manager’s
Review and a record of these measures is shown on pages 1,
5 and 6. The KPIs have not changed from the prior year:
NET ASSET VALUE PER SHARE TOTAL RETURN^
The Directors regard the Company’s net asset value per
share total return as being the overall measure of value
generated by the Portfolio Manager over the long term.
The Board considers the principal comparator to be the
NASDAQ Biotechnology Index (sterling adjusted) (the
Benchmark). OrbiMed’s investment style is such that
performance is likely to deviate from that of the Benchmark.
During the year under review, the Company’s net asset
value per total share return was -11.0%, underperforming
the Benchmark by 16.4% (2022: -33.8%, underperforming
the Benchmark by 26.4%). Since OrbiMed’s date of
appointment (19 May 2005) to 31 March 2023, the
Company’s net asset value per share total return is 756.0%
compared with 795.8% for the Benchmark. Please refer
to the Chairman’s Statement (beginning on page 2) and
the Portfolio Manager’s Review (beginning on page 9) for
further information.
SHARE PRICE TOTAL RETURN^
The Directors also regard the Company’s share price total
return to be a key indicator of performance. This reflects the
Company's share price growth which the Board recognises
is important to investors.
During the year under review the Company’s share price
total return was -12.8% (2022: -37.0%). Since OrbiMed’s
date of appointment (19 May 2005) to 31 March 2023, the
Company’s share price total return is 730.8% compared
with Benchmark performance of 795.8%. Please refer to
the Chairman’s Statement beginning on page 2 for further
information.
SHARE PRICE (DISCOUNT)/PREMIUM TO NET
ASSET VALUE PER SHARE^
The Board regularly reviews the level of the discount/
premium of the Company’s share price to the net asset
value per share and considers ways in which share price
performance may be enhanced, including the effectiveness
of marketing, share issuance and buybacks, where
appropriate. The Board has a discount control mechanism
in place, the aim of which is to prevent the level of the share
price discount to the net asset value per share exceeding
6%. Shareholders should note, however, that it remains
possible for the discount to be greater than 6% on any one
day due to sector volatility and the fact that the share price

continues to be influenced by the overall supply of and
demand for the Company’s shares in the secondary market.
Any decision to repurchase shares is at the discretion of the
Board. 2,421,263 shares were repurchased by the Company
during the year (2022: 576,087).
When the Company's shares trade at a premium to the
net asset value per share, new shares can be issued at a
premium to the net asset value per share.

manage the premium at which the Company’s shares
trade to net asset value per share;
to provide a small enhancement to the net asset value
per share of existing shares through new share issuance
at a premium to the estimated net asset value per share;
to grow the Company, thereby spreading operating
costs over a larger capital base, which should reduce
the ongoing charges ratio; and
to improve liquidity in the market for the Company’s
shares.
As the Company's shares traded at a discount to the net
asset value per share throughout the year, no new shares

The volatility of the net asset value per share in an asset
class such as biotechnology is a factor over which the
Board has no control. The making and timing of any share
buy-backs or share issuance is at the absolute discretion of
the Board. Please see the Chairman’s Statement beginning
on page 2 for further information.
ONGOING CHARGES^
Ongoing charges represent the costs that the Company can
reasonably expect to pay from one year to the next, under
normal conditions. The Board continues to be conscious
of expenses and seeks to maintain a sensible balance
between high quality service and costs. The Board therefore
considers the ongoing charges ratio to be a KPI and reviews

RISK MANAGEMENT
The Board is responsible for managing the risks faced by
the Company. Through delegation to the Audit Committee,
the Board has established procedures to manage risk,
to review the Company’s internal control framework and
to establish the level and nature of the principal risks the
Company is prepared to accept in order to achieve its
long-term strategic objective. At least twice during a year
the Audit Committee carries out a robust assessment of
the principal and emerging risks with the assistance of

they are managed or mitigated are set out on the following
pages.

PRINCIPAL RISKS AND UNCERTAINTIES MANAGEMENT/MITIGATION
MARKET RISK
The Company’s portfolio is exposed to fluctuations in
market prices (changes in broad market measures,
individual security prices and foreign exchange rates)
in the biotechnology sector and the regions in which
it invests, which may result in a reduction in assets
due to market falls and higher volatility.
The biotechnology sector has historically been
more volatile than other equity sectors, reflecting
factors inherent in biotech companies, including
emerging technologies, uncertainty of drug
approval outcomes, regulatory and pricing policy.
More generally, geopolitical and economic
uncertainties have affected markets globally and
are likely to continue to do so. These include the
continued impact of the war in Ukraine and the
effect of sanctions against Russia, resulting in
elevated energy prices. More broadly, inflation may
prove more persistent than had been hoped. This
has driven interest rates higher, increasing the cost
of capital for companies in our investment universe
and leading to concerns about the resilience of
elements of the US banking system, in turn reducing
investors’ risk appetites. Globally, political, military
and commercial tensions between the US/West
and China have put the pace of global economic
growth at risk.
The Portfolio Manager has responsibility for selecting investments in
accordance with the Company’s investment objective and policy and seeks
to ensure that investment in individual stocks falls within acceptable risk
levels. Compliance with the limits and guidelines contained in the Company’s
investment policy is monitored daily by Frostrow and OrbiMed and reported
monthly to the Board.

the risks associated with individual stocks and markets. OrbiMed report at

As part of its review of the going concern and long-term viability of the
Company, the Board also considers the sensitivity of the portfolio to changes in
market prices and foreign exchange rates (see note 14 beginning on page 87)
and the ability of the Company to liquidate its portfolio if the need arose. Further
details are included in the Going Concern and Viability Statements beginning on
page 34.
PORTFOLIO PERFORMANCE
Investment performance may not achieve
the Investment Objective and the value of the
investments held in the portfolio may fall materially
out of line with the sector.
The Portfolio Manager’s approach is expected
to lead to performance that will deviate from
comparators, including both market indices and
other investment companies investing in the
biotechnology sector.
The Board reviews regularly investment performance against the Benchmark
and against the Company’s peer group. The Board also receives regular reports
that analyse performance against other relevant indices. The Portfolio Manager

PRINCIPAL RISKS AND UNCERTAINTIES MANAGEMENT/MITIGATION
SHARE PRICE PERFORMANCE
The risk that the Company’s share price is not
representative of its underlying net assets.
To manage this risk, the Board:
regularly reviews the level of the share price discount/premium to the net asset
value per share and considers ways in which share price performance may
be enhanced, including the effectiveness of marketing and investor relations
services, new share issuance and share buybacks, as appropriate;
has implemented a discount management policy, buying back the Company’s
shares when the level of the share price discount to the net asset value per
share exceeds 6% (in normal market conditions). Further information on this
policy is set out on pages 28 to 29.
may issue shares at a premium to the net asset value per share to help prevent
a share price premium reaching too high a level;
reviews an analysis of the shareholder register at each Board meeting and is
kept informed of shareholder sentiment; and
regularly discusses the Company’s future development and strategy with the
Portfolio Manager and the AIFM.
CYBER RISK
Cyber crime may lead to the disruption or failure
of systems covering dealing, trade processing,

operational functions.
The Board relies on controls in place at OrbiMed, Frostrow, J.P. Morgan, Link
and other third-party service providers.
The Audit Committee reviews the internal controls reports of the principal
service providers, as well as their data storage and information security
arrangements.
KEY PERSON RISK
The risk that the individual(s) responsible for
managing the Company’s portfolio may leave
their employment or may be prevented from
undertaking their duties.
The Board manages this risk by:
appointing OrbiMed, who in turn have appointed Geoff Hsu and, in the
course of the year, Josh Golomb to manage the Company’s portfolio. Mr
Hsu and Mr Golomb are supported by a team of researchers and analysts
dedicated to the biotechnology sector;
receiving reports from OrbiMed at each Board meeting, such reports include

participation of the wider OrbiMed team in investor updates; and
delegating to the Management Engagement Committee, the responsibility
to perform an annual review of the service received from OrbiMed, including,
inter alia, the team supporting the lead managers and their succession plans.
VALUATION RISK
Pursuant to the Investment Policy, the Company
may invest up to 10% of its gross assets in
unquoted investments at the time of acquisition.
The valuation of unquoted assets involves a
degree of subjectivity and there is a risk that
proceeds received on the disposal of unquoted

Company’s portfolio.
Unquoted investments comprised 5.7% of the Company's portfolio at the
year end. The Company’s directly held unquoted investments are valued by
an independent, third-party valuation agent. The Board has established a
Valuation Committee to review the valuations of the unquoted investments
and the methodologies used in the valuations. The valuations are
recommended to the Committee by Frostrow, the Company's AIFM, following
review by its own valuations committee. The Valuation Committee makes
recommendations to the Board, as appropriate. Further information can be

PRINCIPAL RISKS AND UNCERTAINTIES MANAGEMENT/MITIGATION
CLIMATE CHANGE
Climate change events, as well as the introduction
of new regulations designed to combat climate
change, could have an impact on portfolio
companies and their operations, as well as on the
Company’s service providers, potentially affecting
their operating models, supply chains, physical
locations and energy costs.
Although the effects of climate change have yet to be fully determined, the
Board and the Portfolio Manager keep the subject under review.
The Board is conscious that climate change poses a general risk to the
investment environment and, through discussions with the Portfolio Manager,
has noted that the biotechnology industry is not a major contributor to
greenhouse gas emissions. For this reason, the Portfolio Manager does not
consider climate change to be a material ESG consideration when engaging
with investee companies. However energy management is noted as a material
concern in the wider healthcare and pharmaceutical sectors, and this forms
part of OrbiMed’s ESG monitoring. Please refer to pages 24 and 25 for further
information.
COUNTERPARTY RISK
The Company is exposed to credit risk arising
from the use of counterparties. If a counterparty
were to fail, the Company could be adversely
affected through either a delay in settlement or a
loss of assets.

Morgan Securities LLC (the Company’s Custodian and Prime Broker) which is
responsible for the safekeeping of the Company’s assets and provides the loan
facility to the Company. As part of the arrangements with J.P. Morgan Securities
LLC (J.P. Morgan) they may take assets as collateral up to 140% of the value
of the loan drawn down. The assets taken as collateral by J.P. Morgan may be
used, loaned, sold, rehypothecated* or transferred. The level of the Company's
gearing is at the discretion of the AIFM and the Board and the loan can be repaid
at any time, at which point the assets taken as collateral will be released back to
the Company. Any of the Company’s assets taken as collateral are not covered
by the custody arrangements provided by J.P. Morgan.
J.P. Morgan is a registered broker-dealer and is accordingly subject to limits on
rehypothecation* imposed by the U.S. Securities and Exchange Commission
(SEC). In the event of J.P. Morgan’s insolvency, the Company may be unable to
recover in full assets held by it as Custodian or held as collateral.

value of the Company's investments), foreign currency
sensitivity (the sensitivity to changes in key exchange
rates to which the portfolio is exposed) and interest rate
sensitivity (the sensitivity to changes in the interest rate
charged on the Company's loan facility).
With an ongoing charges ratio of 1.1%, the expenses of
the Company are predictable and modest in comparison
with the assets and there are no capital commitments
foreseen which would alter that position.
The Company has a short-term bank facility which can
be used to meet its liabilities. Details of the Company’s

The Company has no employees. Consequently it does
not have redundancy or other employment related
liabilities or responsibilities.
The Audit Committee, as well as considering the potential impact
of the Company’s principal risks and various severe but plausible

current time, the Directors believe they have a reasonable
expectation that the next vote will be passed.
THE BIOTECH GROWTH TRUST PLC Annual Report for the year ended 31 March 2023
STRATEGIC REPORT
35
The closed-ended nature of the Company means that,
unlike open-ended funds, it does not need to realise
investments when shareholders wish to sell their shares;
The Company will continue to be able to fund share
buybacks when required. The Company bought back
2,421,263 ordinary shares in the year under review at a
total cost of £22.6 million and experienced no problem
with liquidity in doing so. It had shareholders’ funds in
excess of £330.2 million at the year end; and
The long-term performance of the Company will continue
to be satisfactory.
ENVIRONMENTAL, SOCIAL, COMMUNITY AND
HUMAN RIGHTS MATTERS
As an externally managed investment trust, the Company
does not have any employees or maintain any premises,
nor does it undertake any manufacturing or other
physical operations itself. All its operational functions are
outsourced to third party service providers. Therefore, the
Company has no material, direct impact on the environment
or any particular community and, as a result, the Company
itself has no environmental, human rights, social or
community policies.
Under the Listing Rules, the Company is also exempt
from reporting against the Taskforce for Climate-Related
Financial Disclosures (TCFD) framework. However, the
Board recognises that climate change poses a general risk
to the investment environment and has discussed with the
Portfolio Manager the potential impact of climate change
risk on the Company's investments.
The Board believes that consideration of environmental,
social and governance (“ESG”) factors is important to
shareholders and other stakeholders, and has the potential
to protect and enhance investment returns. The Portfolio
Manager’s investment criteria ensure that ESG factors are
integrated into their investment process and best practice
in this area is encouraged by the Board. The Portfolio
Manager engages with the Company’s underlying investee
companies in relation to their corporate governance
practices and the development of their policies on social,
community and environmental matters. Further information
on OrbiMed’s responsible investing policy, including their
approach to the consideration of climate change in their
investment process, can be found on pages 24 and 25.
The Board is committed to carrying out the Company’s

approach to bribery, corruption, and tax evasion. As such,
policies and procedures are in place to prevent this. In
carrying out the Company’s activities, the Board aims to
conduct itself responsibly, ethically and fairly. The Board’s
expectations are that the Company’s principal service
providers have appropriate governance policies in place.
PERFORMANCE AND FUTURE DEVELOPMENTS
A review of the Company’s year, its performance and the
outlook for the Company can be found in the Chairman’s
Statement beginning on page 2 and in the Portfolio
Manager’s Review beginning on page 9.
The Company’s overall strategy remains unchanged.

and interacts with the other service providers including the Depositary, Custodian and Registrar,
on behalf of the Board, on a daily basis. This can be through email, one-to-one meetings and/or

The Board considers that reporting against the principles

by the Financial Reporting Council) will provide better
information to shareholders. By reporting against the
AIC Code, the Company meets its obligations under the
UK Code (and associated disclosure requirements under

directors’ remuneration and the internal audit function.
The AIC Code is available on the AIC’s website
www.theaic.co.uk and the UK Code can be viewed on the

BOARD LEADERSHIP AND PURPOSE
PURPOSE AND STRATEGY
The purpose and strategy of the Company are described in
the Strategic Report.
BOARD CULTURE
The Board aims to consider and discuss fully differences
of opinion, unique vantage points and to exploit fully areas
of expertise. The Chairman encourages open debate
to foster a supportive and cooperative approach for all
participants. Strategic decisions are discussed openly and
constructively. The Board aims to be open and transparent
with shareholders and other stakeholders and for the
Company to conduct itself responsibly, ethically and fairly
in its relationships with service providers.
The Board has gained assurance on whistleblowing
procedures at the Company’s principal service providers
to ensure employees at those companies are supported in
speaking up and raising concerns. No concerns relating to
the Company were raised during the year.
SHAREHOLDER RELATIONS
The Company has appointed Frostrow to provide marketing
and investor relations services in the belief that a well-
marketed investment company is more likely to grow over
time, have a more diverse, stable list of shareholders and
its shares will trade closer to the net asset value per share
over the long run. Frostrow actively promotes the Company
as set out on pages .
SHAREHOLDER COMMUNICATIONS
The Board, the AIFM and the Portfolio Manager consider
maintaining good communications with shareholders
to be a priority. They engage with larger shareholders
through meetings and presentations. Shareholders are
informed by the publication of annual and half-yearly

are supplemented by the daily release of the net asset
value per share to the London Stock Exchange and the
publication of monthly fact sheets. All this information,
including interviews with the Portfolio Manager, is available
on the Company’s website at www.biotechgt.com.
The Board monitors changes to the share register of
the Company; it also reviews correspondence from
shareholders (if any) at each meeting and maintains regular
contact with major shareholders. Shareholders who wish to
raise matters with a Director may do so by writing to them

investors in particular. Shareholders are encouraged to
attend the AGM, where they are given the opportunity to
question the Chairman, the Board and representatives of the
Portfolio Manager. In addition, the Portfolio Manager makes
a presentation to shareholders covering the investment
performance and strategy of the Company at the AGM.

DIVISION OF RESPONSIBILITIES
THE CHAIRMAN AND THE SID
The Chairman’s primary role is to provide leadership to the
Board, assuming responsibility for its overall effectiveness
in directing the Company.
The Senior Independent Director (“SID”) serves as
a sounding board for the Chairman and acts as an
intermediary for the other Directors and the shareholders.
A full description of the responsibilities of the Chairman
and the SID can be found on the Company’s website: www.

DIRECTOR INDEPENDENCE
The Board consists of six non-executive Directors. All of the
Directors except for Geoff Hsu are independent of OrbiMed

of the Board is a Director of another investment company
managed by OrbiMed, nor has any Board member (with
the exception of Geoff Hsu) been an employee of OrbiMed
or any of the Company’s service providers. Further details
regarding the Directors can be found on pages .
The Board carefully considers the various guidelines for
determining the independence of non-executive Directors,
placing particular weight on the view that independence
is evidenced by an individual being independent of mind,
character and judgement. All Directors, with the exception
of Geoff Hsu, are presently considered to be independent.
Directors obtain approval from the Chairman prior to
accepting any new appointments.
BOARD MEETINGS
The Board is responsible for the effective stewardship of
the Company’s affairs. Strategy issues and all material
operational matters are considered at its meetings.
The Board meets formally at least four times each year. The
primary focus at regular Board meetings is the review of
investment performance and associated matters, including
asset allocation, marketing/investor relations, peer group
information and industry issues.

price and net asset value performance.
The Board is responsible for setting the Company’s
corporate strategy and reviews the continued
appropriateness of the Company’s investment objective,
investment strategy and investment restrictions at each
meeting.
MATTERS RESERVED FOR DECISION BY THE BOARD
The Board has adopted a schedule of matters reserved for its
decision. This includes:
decisions relating to the strategic objectives and overall
management of the Company, including the appointment
or removal of the Portfolio Manager and other service
providers, establishing the investment objectives,
restrictions, strategy and performance comparators;
 
statements, recommendation or declaration of any
dividends, determining the policy on share issuance and
buybacks;
the Company’s internal controls, corporate governance
structure, policies and procedures; and
matters relating to the Board and its committees,
including the appointment of directors.
Day-to-day portfolio management is delegated to OrbiMed
and operational management is delegated to Frostrow.
The Board takes responsibility for the content of
communications regarding major corporate issues, even if
OrbiMed or Frostrow acts as spokesman. The Board is kept
informed of relevant promotional material that is issued by
Frostrow.
RELATIONSHIP WITH SERVICE PROVIDERS
Representatives of the Portfolio Manager and the AIFM are
in attendance at each Board meeting. The Management
Engagement Committee evaluates the performance of
all the Company’s service providers as well as the terms
and conditions on which they are engaged. At the most

that all the service providers were performing well and
recommended to the Board that they should be retained on
the existing terms and conditions. Please refer to page 4 for
further information on the Committee’s assessment of the
AIFM and the Portfolio Manager.
EXERCISE OF VOTING POWERS
The Board and the AIFM have delegated authority to
the Portfolio Manager to vote the shares owned by the
Company. The Portfolio Manager has been instructed to
submit votes in respect of such shares wherever possible.
The Portfolio Manager may refer to the Board or the AIFM
on any matters of a contentious nature. The Board has

their approach.
The Company does not retain voting rights on any shares
that are subject to rehypothecation* in connection with the
loan facility provided by J.P. Morgan Securities LLC.
STEWARDSHIP AND ORBIMED’S RESPONSIBLE
INVESTING POLICY
The Board recognises that Environmental, Social and
Governance (“ESG”) issues can impact the performance of
investments. The Board has delegated authority to OrbiMed
to evaluate investee companies’ performance and engage
with their management teams on material ESG issues. These
matters and any other ESG related issues are discussed
regularly with the Board.
INDEPENDENT PROFESSIONAL ADVICE
The Directors have access to the advice and services of
a specialist investment trust company secretary, who
is responsible for advising the Board on all governance
matters. The Company Secretary ensures governance
procedures are followed and that the Company complies
with applicable statutory and regulatory requirements.
The Board has formalised arrangements under which
the Directors, in the furtherance of their duties, may seek
independent professional advice at the Company’s expense.
No such advice was sought during the year.

INDUCTION AND TRAINING
New appointees to the Board are provided with a full
induction programme. The programme covers the
Company’s investment strategy, policies and practices.
The Directors are also given key information on the
Company’s regulatory and statutory requirements as they
arise including information on the role of the Board, matters
reserved for its decision, the terms of reference of the
Board committees, the Company’s corporate governance

role and Directors are encouraged to participate in training
courses where appropriate.
DIVERSITY POLICY
The Board supports the principle of Boardroom diversity,
of which gender and ethnicity are two important aspects.
The Company’s policy is that the Board and its committees
should be comprised of directors with a diverse range of
skills, knowledge and experience and that appointments
should be made on merit against objective criteria,
including diversity in its broadest sense.
The objective of the policy is to have a broad range of
approaches, backgrounds, skills, knowledge and experience
represented on the Board. To this end, achieving a diversity
of perspectives and backgrounds on the Board will be
a key consideration in any director search process. The
Board encourages any recruitment agencies it engages to

agreed for each appointment and, from the shortlist, aims
to ensure that a diverse range of candidates is brought
forward for interview.
The Board will give due regard to the new diversity
targets in the Listing Rules (set out overleaf), but will not
discriminate unfairly on the grounds of gender, ethnicity,
age, sexual orientation, disability or socio-economic
BOARD COMPOSITION, SUCCESSION AND
EVALUATION
SUCCESSION PLANNING
The Board, meeting as the Nominations Committee,
regularly considers its structure and recognises the need
for progressive refreshment.
The Board has an approved succession planning policy to
ensure that (i) there is a formal, rigorous and transparent
procedure for the appointment of new directors; and (ii) the
Board is comprised of members who collectively display
the necessary balance of professional skills, experience,
length of service and industry knowledge.
POLICY ON THE TENURE OF THE CHAIRMAN AND
OTHER NON-EXECUTIVE DIRECTORS
The tenure of each independent, non-executive director,
including the Chairman, is not ordinarily expected to exceed
nine years. It should be noted that, in practice, the date for
departure from the Board may be on the Annual General
Meeting following this anniversary. However, the Board has
agreed that the tenure of the Chairman may be extended for
a limited time provided such an extension is conducive to the
Board’s overall orderly succession. The Board believes that
this more flexible approach to the tenure of the Chairman is
appropriate in the context of the regulatory rules that apply to
investment companies, which ensure that the chair remains
independent after appointment, while being consistent with
the need for regular refreshment and diversity.
Notwithstanding this expectation, the Board considers that
a Director’s tenure does not necessarily reduce his or her
ability to act independently and will continue to assess
each Director’s independence annually, through a formal
performance evaluation.
APPOINTMENTS TO THE BOARD
The rules governing the appointment and replacement of
Directors are set out in the Company’s articles of association
and the aforementioned succession planning policy.
Where the Board appoints a new Director during the year,
that Director will stand for election by shareholders at the
next AGM. Subject to there being no conflict of interest, all
Directors are entitled to vote on candidates for appointment
to the Board and on the recommendation for shareholders’
approval for the Directors seeking re-election at the AGM.
When considering new appointments, the Board endeavours
to ensure that it has the capabilities required to be effective

appointment.
The Board has noted the FCA's new Listing Rules which
require companies to report against the following diversity
targets:
(a) At least 40% of individuals on the board are women;
(b) At least one of the senior board positions (Chair, CEO,
CFO or SID) is held by a woman; and
(c) At least one individual on the board is from a minority
ethnic background.
As an externally managed investment company, the
Company does not have the positions of CEO or CFO and
therefore, as permitted by the Listing Rules, it has not
reported against the second target as it is not applicable.
In the absence of the aforementioned roles, the Board
considers the Chair of the Audit Committee to be a senior
position and notes that the role is currently held by a woman.
As shown in the tables below, the Company has met the third

will have regard to this target in future director recruitment
processes, due to the Board’s small size, vacancies and
recruitment opportunities arise relatively infrequently and
therefore the target may take some time to achieve.

The format of the above tables is prescribed in the Listing Rules. However, as an externally managed investment trust, the Company has no executive
management functions, including the roles of CEO and CFO, and the Company has therefore excluded columns relating to executive management.
The information above was obtained by asking the Directors to indicate on an anonymous form how they should be categorised
for the purposes of the Listing Rules disclosures.
BOARD EVALUATION
During the year an internal review of the Board, its
committees and individual Directors (including each
Director’s independence) was carried out by the Board, in the
form of electronic performance evaluation questionnaires.
The review concluded that the Board worked in a collegiate,

that the structure, mix of skills and operation of the Board, its

undertaken in 2021, it is anticipated that the next such
review will be in 2024.

PERFORMANCE FEE
The Portfolio Manager is entitled to the payment of a
performance fee which is dependent on the long-term
performance of the Company. The performance fee
is calculated by reference to the amount by which the
Company’s net asset value (NAV) has outperformed the
NASDAQ Biotechnology Index (sterling adjusted), the
Company’s benchmark index.
The fee is calculated quarterly by comparing the cumulative
performance of the Company’s NAV with the cumulative
performance of the Benchmark since the commencement

over the Benchmark. Provision is also made within the daily
NAV per share calculation as required and in accordance
with generally accepted accounting standards.
In order to ensure that only sustained outperformance
is rewarded, at each quarterly calculation date any
performance fee is based on the lower of:
(i) the cumulative outperformance of the NAV over the
Benchmark as at the quarter end date; and
(ii) the cumulative outperformance of the NAV over the
Benchmark as at the corresponding quarter end date in
the previous year.

In addition, a performance fee only becomes payable to the

AIFM AND PORTFOLIO MANAGER
EVALUATION AND RE-APPOINTMENT
The performance of the AIFM and the Portfolio Manager
is reviewed by the Board with a formal evaluation being
undertaken by the Management Engagement Committee
(the MEC) each year. As part of this process, the Board
monitors the services provided by the AIFM and the
Portfolio Manager and receives regular reports and views
from them. The Board also receives comprehensive
performance measurement reports to enable it to
determine whether or not the performance objectives
set by the Board have been met. The MEC reviewed the
appointment of the AIFM and the Portfolio Manager in

theBoard.
The Board believes the continuing appointment of the
AIFM and the Portfolio Manager is in the interests of
shareholders as a whole. In coming to this decision, the
Board took into consideration the following reasons:
the quality and depth of experience allocated by the
Portfolio Manager to the management of the portfolio
and the level of performance of the portfolio in absolute
terms and also by reference to the Benchmark;
the quality and depth of experience of the company
management, company secretarial, administrative
and marketing team that the AIFM allocates to the
management of the Company; and
the terms of the AIFM and Portfolio Management
Agreements, in particular the level and method of
remuneration and the notice period, and the comparable
arrangements of a group of the Company's peers.
The Board resolved that the AIFM and the Portfolio
Manager should continue to be appointed on the same
terms and conditions set out above.
A number of minor updates to the AIFM and Portfolio
Management Agreements were agreed with Frostrow and
OrbiMed in order to:
reflect changes in UK legislation following the UK's exit
from the European Union;

For the avoidance of doubt, no changes were made to the
material terms and conditions of the agreements including
the fee arrangements and the notice periods.
LOAN FACILITY
The Company’s borrowing requirements are met through
the utilisation of a loan facility, repayable on demand,
provided by J.P. Morgan Securities LLC. The potential draw

reviewing and amending, where necessary, the
Company’s register of key risks in light of changes to
the portfolio and the investment environment; and
gaining an overall understanding of the performance of
the portfolio both in capital and revenue terms through
comparison to the Benchmark.
VALUATION OF UNQUOTED INVESTMENTS
The Company has the ability to make unquoted

of acquisition. This does not include any holdings that
are subject to an IPO lock-in (see glossary beginning on
). Both the Directors and the AIFM need to ensure
that an appropriate value is placed on such investments
within the Company’s published net asset value. The
Committee has worked with the Portfolio Manager and
the AIFM to establish clear guidelines for the valuation
of unquoted investments, including the use of valuations
produced by independent external valuers, where
appropriate.
Last year, the Board established a Valuation Committee which
considers in detail the valuations and valuation methodologies
employed in respect of the unquoted assets. The Valuation
Committee also considers whether the third party valuer has
followed appropriate standards and established valuation
procedures, taking into account the views of the Company's
external auditor. The Audit Committee reviewed the minutes
of the Valuation Committee meetings held after the year end
and the half year end and noted the recommendations it had
made to the Board.
RECOGNITION OF REVENUE FROM INVESTMENTS
The Committee took steps to gain an understanding
of the processes in place to record investment income
and transactions. The Committee sought and received

Committee noted and took comfort from the segregation
of duties in place between the AIFM and the Custodian and
Prime Broker.
TAXATION – INVESTMENT TRUST STATUS

meeting and also as part of the monthly compliance
monitoring report sent to the Board; and
understanding the risks and consequences if the
Company breaches this approval in future years.
CALCULATION OF AIFM, PORTFOLIO
MANAGEMENT AND PERFORMANCE FEES
The AIFM, portfolio management and performance
fees are calculated in accordance with the AIFM and
Portfolio Management Agreements. Both the Committee
and the Auditor review and agree the calculation of any
performance fee that becomes payable, however no
performance fees became payable during the year under
review.
OTHER REPORTING MATTERS
AUDIT REGULATION
The Committee has not had to consider any new audit
regulations in the past year. It has, however, taken note
of reporting guidance and thematic reviews published by
the FRC and determined how to apply any relevant best
practice to the Company’s reporting.
The Committee also reviews the outcomes of the FRC’s

The Committee has noted the government response to the
consultation on strengthening the UK’s audit, corporate
reporting and corporate governance systems. We await

Authority, amongst other changes.
INVESTMENT PERFORMANCE
The Committee gained an overall understanding of the
performance of the investment portfolio, both in capital
and revenue terms, through ongoing discussions with the
Portfolio Manager and also with comparison to suitable key
performance indicators.
ACCOUNTING POLICIES
During the year, the Committee ensured that the
accounting policies, as set out on pages  to , were
applied consistently throughout the year. In light of there
being no unusual transactions during the year or other
possible reasons, the Committee agreed that there was no
reason to change the policies.

The Committee also considered the longer-term viability of
the Company in connection with the Board’s statement in
the Strategic Report on pages  and . The Committee

uncertainties and the results of stress tests. The tests
assumed falls in the Company's NAV and reductions in the
liquidity of the portfolio and then examined the effect this
would have on the Company's expenses and the Company's
ability to meet its liabilities as they fell due.
In even the most stressed scenario, the Company was

RISK MANAGEMENT AND INTERNAL CONTROLS
The Board has overall responsibility for the Company’s
risk management and internal control systems and for
reviewing their effectiveness. Operational responsibility
is delegated to the Audit Committee. The Company’s
internal control structure is summarised on page . The
Company applies the guidance published by the Financial
Reporting Council on internal controls. Internal control
systems are designed to manage, rather than eliminate,
the risk of failure to achieve the business objective and
can provide only reasonable and not absolute assurance
against material misstatement or loss. These controls aim

A description of the principal risks facing the Company
(including emerging risks) and an explanation of how
they are managed is provided in the Strategic Report on
pages . The Directors have established an ongoing
process for identifying, evaluating and managing the risks
faced by the Company, including emerging risks, which are
recorded in a risk register. The Committee reviewed the
risk register during the year to ensure the risks facing the

the risk scores were appropriate. The Audit Committee, on
behalf of the Board, assesses the likelihood of occurrence
and the possible impact of each risk. The Committee then
considers the Company’s ability to reduce or mitigate the
incidence and impact of these risks on its performance and
records the controls in place.
The Committee reviewed the effectiveness of the
Company’s risk management and internal controls
systems during the year. As an externally managed
investment trust, the Company is reliant on the operational
systems of its service providers. Therefore the Audit
Committee examined the internal control reports of the
Company’s principal service providers. The Committee also
reviewed the cyber security strategies adopted by each of
the principal service providers and spoke with members of
the Portfolio Manager’s risk management and investment
compliance teams to ensure their processes remain
robust. There were no changes to the Company’s risk

DIRECTORS’ REMUNERATION REPORT
The Directors’ Remuneration Report is subject to an annual advisory shareholder vote and therefore an ordinary resolution
for the approval of this report will be put to shareholders at the Company’s forthcoming Annual General Meeting (AGM).
The law requires the Auditor to audit certain disclosures provided in this report. Where disclosures have been audited,
they are indicated as such and the Auditor’s opinion is included in their report to shareholders beginning on page 65. The
Remuneration Policy on page 64 forms part of this report.
The independent Directors on the Board consider the framework for the Directors’ remuneration on an annual basis. The
independent Directors review the ongoing appropriateness of the Company’s remuneration policy and the remuneration of
individual Directors by reference to the activities of the Company and in comparison with other companies of a similar structure
and size. This is in line with the AIC Code.
The simple fee structure reflects the non-executive nature of the Board, which itself reflects the Company’s business model
as an externally managed investment trust (please refer to the Business Review beginning on page 26 for more information).
Accordingly, statutory reporting requirements relating to executive directors’ and employees’ pay do not apply.
No communications have been received from shareholders regarding Directors’ remuneration.
During the year, having noted that the directors’ base fee rate had remained unchanged for two years and that there has been
a period of high inflation during that time, it was agreed that each Director’s fees should be increased by 5.0% with effect
from 1 April 2023.
The table below shows the level of fees paid to Directors and the percentage increase from the prior year:

Key audit matter How the scope of our audit addressed the key audit matter
Valuation and ownership of investments, Note 1 and note 8
The investment portfolio at the year-
end comprised of quoted and unquoted
investments.
We consider that the valuation and
ownership of investments is the most
nancial
statements and underpin the principal
activity of the entity. Given the

is a risk that an error in their valuation
could have a material impact on the

The investment valuations are prepared
by the Alternative Investment Fund
Manager (AIFM), Frostrow Capital LLP
and the Portfolio Manager, OrbiMed
Capital LLC, who are remunerated
based on the net asset value of the
Company. The investment valuations
are reviewed and approved by the
Board. Notwithstanding this review,
there is a potential risk of misstatement
in the investment valuations. The
majority of the investments are Level
1 quoted investments which we do not
consider to be a highly subjective area.
We do note there are three unquoted
investments which are collectively
material, the valuation of which
involves a higher level of judgment and
subjectivity.
There is also a risk of error in the
recording of investment holdings such
that the investments are misstated due
to the incorrect use of number of shares
held by the Company.
For these reasons and the materiality of

statements as a whole, we considered
this to be a key audit matter.
We responded to this matter by testing the valuation and ownership of the whole
portfolio of investments.
In respect of the quoted investments valuation testing we have for 100% of the
portfolio:

appropriate by corroborating these to independent sources;
Tested the computational accuracy by multiplying the number of shares held per
the statement obtained from the custodian by the valuation per share; and
Assessed if there were contra indicators, such as liquidity considerations,
to suggest bid price is not the most appropriate indication of fair value by
considering the realisation period for individual holdings.
In respect of unquoted investments valuation testing we have for 100% of the
portfolio:
Considered whether the valuation methodology is the most appropriate in
the circumstances under the International Private Equity and Venture Capital
Valuation (“IPEV”) Guidelines;

and our own research;
Recalculated the value attributable to the Company;
Where applicable, we performed back testing by comparing the valuation at IPO
to the most recent fair value per the books to assess the ability of the Company
in valuing unquoted investments;
Considered the competence, capabilities and expertise of the management’s

considered the independence and objectivity of the expert through review of the
independence declaration made by the expert to the Company. We considered
the appropriateness of the methodology and assumptions employed by the
expert through review of the accounting framework and valuation guidelines
followed.
Where appropriate, we performed a sensitivity analysis by developing our
own point estimate where we considered that alternative input assumptions
could reasonably have been applied and we considered the overall impact of
such sensitivities on the portfolio of investments in determining whether the
valuations as a whole are reasonable and free from bias.

from the custodian, J.P. Morgan Securities LLC for quoted investments; and
from the investee companies for the unquoted investments.
Key observations:
Based on our procedures performed we did not identify any matters to suggest
the valuation or ownership of both quoted and unquoted investments was not
appropriate.

We apply the concept of materiality both in planning and performing our audit, and in evaluating the effect of misstatements.
We consider materiality to be the magnitude by which misstatements, including omissions, could influence the economic

impacting revenue return of £164,000 (2022:£197,000) based on 5% of overall materiality (2022: 5% of overall materiality).
Reporting threshold
We agreed with the Audit Committee that we would report to them all individual audit differences in excess of £164,000
(2022:£197,000). We also agreed to report differences below this threshold that, in our view, warranted reporting on
qualitative grounds.

Extent to which the audit was 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:
Non-compliance with laws and regulations
Based on:
Our understanding of the Company and the industry in
which it operates;
Discussion with management and those charged with
governance; and
Obtaining and understanding of the Company’s policies
and procedures regarding compliance with laws and
regulations,

UK tax legislation as any non-compliance of this would
lead to the Company losing various deductions and
exemptions from corporation tax.
Our procedures in respect of the above included:

underlying supporting documentation;
Enquiries of the AIFM, Administrator and those charged
with governance relating to the existence of any non-
compliance with laws and regulations;
Review of a sample of legal invoices to look for
potential non-compliance with laws and regulations or
undisclosed contingencies and commitments;
Reviewing minutes of meetings of those charged with
governance throughout the period for instances of non-
compliance with laws and regulations; and
Reviewing the calculation in relation to Investment Trust
compliance to check that the Company was meeting its
requirements to retain its Investment Trust Status.

material misstatement including fraud.
Our risk assessment procedures included:
Enquiry with management and those charged with
governance regarding any known or suspected
instances of fraud;
Obtaining an understanding of the Company’s policies
and procedures relating to:
o Detecting and responding to the risks of fraud; and
o Internal controls established to mitigate risks related
to fraud;
Review of minutes of the Board and other committee
meetings throughout the period for any known or
suspected instances of fraud;
Discussion amongst the engagement team as to

Obtaining an understanding of the control environment
in monitoring compliance with laws and regulations.
Based on our risk assessment, we considered the areas
most susceptible to be valuation of unquoted investments
and management override of controls.
Our procedures in respect of the above included:
The procedures set out in the Key Audit Matters section

recognising that the risk of not detecting a material
misstatement due to fraud is higher than the risk of
not detecting one resulting from error, as fraud may
involve deliberate concealment by, for example, forgery,
misrepresentations or through collusion. There are inherent
limitations in the audit procedures performed and the
further removed non-compliance with laws and regulations

USE OF OUR REPORT
This report is made solely to the Company’s members,
