Operational highlights

Financial highlights

•  In March 2020, Synairgen raised £14.0 million in a 

heavily oversubscribed equity issue to fund its COVID-19 
related activities and strengthen its balance sheet.

•  Research and development expenditure for the year 
amounted to £3.46 million (2018: £3.23 million) and 
the majority of this expenditure was focussed on 
running the IFN-beta Phase II clinical trial in COPD.

•  The loss from operations for the year ended  

31 December 2019 was £4.82 million  
(2018: loss £4.13 million).

•  Cash and bank deposits of £2.45 million at  

31 December 2019 (31 December 2018: £5.33 million).

•  Synairgen has paused the SG015 trial of SNG001 

(inhaled interferon-beta 1a) in COPD patients due to 
the prevalence of COVID-19 in the community, with 
109 out of 120 patients recruited. The Company has 
received approval from the Medicines and Healthcare 
products Regulatory Agency (MHRA) to conduct an 
unplanned interim analysis on the grounds that 
data from the 109 COPD patients with confirmed 
viral infection generates useful safety, biomarker 
and potentially efficacy data to support ongoing 
trials of SNG001 in COVID-19 patients. The results 
of this interim analysis are expected this Summer.

•  In March 2020, Synairgen announced it had 

received expedited approvals from the MHRA 
and Health Research Authority (HRA) to conduct a 
trial of SNG001 in COVID-19 patients (SG016).

•  The SG016 study has progressed well, with 98 
patients out of the target of 100 now dosed 
in the hospital setting. Results from this part 
of the study are expected in July 2020.

•  Synairgen is extending the SG016 study to patients  
in the home environment with confirmed COVID-19,  
to initiate dosing with SNG001 (or placebo) earlier 
in the course of the illness and before severe lower 
respiratory tract symptoms develop. Dosing in the home 
environment is expected to commence in May 2020.

Strategic Report

The directors present their Strategic Report 
for the year ended 31 December 2019.

Principal activities and strategy

Synairgen plc (the ‘Company’) is the holding company for 
Synairgen Research Limited, a respiratory drug discovery  
and development company.

Synairgen leverages its deep understanding of respiratory biology 
to discover and develop novel therapies in areas of high unmet 
respiratory medical need, including severe asthma, chronic 
obstructive pulmonary disease (COPD), idiopathic pulmonary 
fibrosis (IPF) and respiratory viruses such as COVID-19. Using 
our BioBank platform (consisting of human tissue models of 
respiratory disease), and our clinical trial capabilities, Synairgen’s 
strategy is to identify novel drug targets, progress them through 
early stage clinical trials and license them to partners to advance 
through to commercialisation. A glossary on pages 50 to 52 
provides additional explanation of some of the more detailed 
scientific and clinical terminology.

Operating Review 

Summary
In 2019 we recruited steadily into our SG015 Phase II trial 
of SNG001 in patients with COPD. Due to the emergence of 
the SARS-CoV-2 virus, which causes COVID-19, recruitment 
into this trial was paused from March 2020. Post period-
end, addressing whether SNG001 has potential utility as a 
therapeutic for COVID-19 has been a key priority for the 
business. Synairgen has commenced a placebo-controlled 
trial of SNG001 in hospitalised patients with COVID-19 and is 
aiming to commence dosing in home-based ‘at risk’ patients 
imminently. We are also investing in the supply chain to 
minimise the impact of long lead times in the event that there 
is demand for SNG001 to treat COVID-19 patients. Separately, 
Synairgen’s partner in the LOXL2 programme, Pharmaxis, has 
continued its licensing discussions during the period, which 
in time could potentially yield financial benefit to Synairgen.

Progress with SGN001 programme
SNG001 is a formulation of IFN-beta 1a (IFN-beta) for 
inhalation via a nebuliser. Compared to injected formulations 
of IFN-beta, which have been used extensively as a treatment 
for patients with multiple sclerosis, SNG001 is pH neutral and 
is free of excipients which may be pharmacologically active 
in the airways such as mannitol and human serum albumin. 

The relevance of interferons in virus defence
The Type I interferons, such as interferon alpha (IFN-alpha) 
and interferon beta (IFN-beta), are key mediators involved in 
responses to viral infection. Although these antiviral proteins 

bind to the same receptor, they differ in their antiviral and 
immunomodulatory effects. Cells produce interferons as an 
innate immune response to combat a viral infection. It is this 
innate immune response that provides a first line of defence 
against viruses until the adaptive immune system generates 
antibodies, which clear the virus infection and can provide long 
term immunity. IFN-alpha is produced in large quantities by 
specialised white blood cells called plasmacytoid dendritic cells 
and is approved for use in some systemic infections such as  
hepatitis. IFN-beta is made by many cell types, including epithelial 
cells and fibroblasts where it is produced as an immediate 
local response to viral infection and triggers an antiviral 
programme preparing the tissue to fight off the infection.  

Various groups have shown that upon infection with a respiratory 
virus IFN-beta production is deficient in lung epithelial cells of 
patient groups such as those with asthma, COPD, cystic fibrosis, 
and also the elderly, who can become severely ill due to common 
respiratory viruses (e.g. influenza, RSV, rhinovirus) each winter.1 
The reasons for this are being explored, however treatment with 
exogenous IFN-beta in vitro has been shown to be protective 
irrespective of background co-morbidity risk factors and whether 
cells are treated with IFN-beta pre- or post-infection.

SNG001 programme in asthma and COPD
SNG001 has been progressed through three clinical trials in 
asthma. A Phase I safety and proof-of- delivery trial showed 
a dose-dependent upregulation of antiviral responses 
measured in lung (sputum) samples. In two Phase II trials, 
SNG001 accelerated a recovery in lung function from the 
losses caused by a range of common respiratory viruses.  
With the development of an immediate point-of-care testing 
system to validate viral infection in patients (bioMérieux 
BioFire FilmArray technology) in 2018, the SNG001 
programme switched from asthma to COPD, a condition 
where the impact of viral infections can be very severe.

COPD patients are approximately five times more likely to 
become severely ill due to respiratory viruses than asthmatic 
patients,2 and have always been recognised as a larger potential 
market for a broad spectrum antiviral product which could 
prevent exacerbations or accelerate recovery from exacerbation. 
However, half of infectious COPD exacerbations are caused by 
bacteria, with no virus present. This meant use of SNG001 in 
the context of COPD would be very challenging without a 
point-of-care test for viral infections. The bioMérieux BioFire 
FilmArray and other technologies which have subsequently 
become available, ensure the selection and treatment of solely 
those patients where the presence of a virus is confirmed.

In 2018 Synairgen commenced a two-part COPD trial (SG015) to 
assess initially, the safety and lung antiviral biomarker responses 
to SNG001 in the absence of viral infection. In the first part of 
the trial SNG001 was well tolerated in patients with moderate 
to severe COPD. We also observed a strong antiviral biomarker 
signal, which was comparable to the response previously 
observed in asthma. This paved the way to proceed into the 
second part of the trial, which was designed to dose 120 patients 
with confirmed naturally-occurring respiratory virus infections. 
Recruitment into the trial commenced in earnest in January 2019 
and was progressing well until the emergence of SARS-CoV-2 
which made it difficult to test for virus and dose patients without 
potentially exposing them and research staff to SARS-CoV-2 virus. 
Hence in March 2020 the trial was paused, with 109 out of the 
targeted 120 patients recruited. We have received approval 
from the Medicines and Healthcare products Regulatory Agency 
(MHRA) to run an unplanned interim analysis on the grounds 
that data from 109 COPD patients with confirmed viral infection 
generates useful safety, biomarker and potentially efficacy data 
to support ongoing trials of SNG001 in COVID-19 patients.  
We expect to have data from this interim analysis in the  
Summer 2020. In due course we will consider options as  
to how to progress SNG001 in COPD.

Rationale for using SNG001 in COVID-19 patients
The high-risk groups for severe COVID-19 illness are the elderly 
and those with chronic co-morbidities. These groups overlap 
with the observed innate immune deficiency in the elderly and in 
patients with COPD, many of whom will have other co-morbidities. 
Further to this compromised immunity, some viruses, including 
coronaviruses, have evolved to suppress IFN-beta production to 
enable them to evade the “first response” immune system.  
This therefore provides two reasons to warrant assessment of 
SNG001 in COVID-19 patients. In the laboratory, IFN-beta has 
been shown to protect cells from infection by SARS-CoV-2,  
the virus which causes COVID-19.3

Clinical trial (SG016) in COVID-19 patients

Patients initiated in hospital
In late March 2020, Synairgen dosed the first COVID-19 patients 
in a randomised placebo-controlled trial. This trial has received 
‘National Priority’ status from the National Institute of Health 
Research, thereby enabling 9 top UK respiratory Translational 
Research Centre sites to participate. The trial has now recruited 
98 COVID-19 patients who are hospitalised but breathing 
unaided; the trial does not include severe patients requiring 
ventilatory support. There has been a notable slowdown 
in recruitment during the last three weeks as the incidence 

of COVID-19 has reduced, but we would hope to reach our 
recruitment target of 100 shortly. A planned review of the data 
will inform onward clinical trial activity, which will be agreed 
with regulatory agencies. Conducting high quality clinical trials 
in the current environment is very challenging. It is the efforts 
and support of the participating centres and key contributing 
partners, suppliers and the regulatory bodies which have 
enabled this trial to happen quickly. We anticipate producing 
initial trial data in July 2020.

Patients initiated at home
The SG016 protocol also allows the dosing of patients in the 
home environment; the objective being to initiate treatment 
earlier than the hospital study to prevent development of 
significant lower respiratory tract illness and subsequent 
hospitalisation. In order to minimise risks to patients and 
healthcare workers in this setting, all visits will be conducted  
by video link. Dosing is set to commence in May 2020.

Patients will interact with the trial team using Skype/Teams/
Zoom or their preferred choice of video conferencing as soon as 
COVID-19 symptoms develop. Patients will be informed about 
the trial and provide online consent. Patients will self-swab 
under video supervision. Within a few hours of the swab having 
been taken, the virus test results will be known. If positive for 
SARS-CoV-2, the drug (placebo or SNG001), aerosol delivery 
device, and other trial equipment will be despatched to the 
patient. Each dose will be taken under video supervision. 
Endpoints will also be assessed during the video calls.

This is the first trial of its type to be conducted “remotely”  
in this way and if successful, may point towards a potential 
domiciliary care protocol for this and future viral outbreaks.

Supply chain in the event of success
In the event that the current trials prove successful, 
Synairgen has made good progress with suppliers to scale 
up production of SNG001 rapidly with the aim of being able 
to supply meaningful quantities by the end of this year.

LOXL2 inhibitor programme 
Pharmaxis, the Company’s Australian-based partner 
for the antifibrotic LOXL2 inhibitor programme, has 
updated the market (on 30 April 2020) stating that it 
is currently pursuing a number of different partnering 
options with international pharma companies to enable 
this drug to enter the clinic in phase 2 trials and will 
provide more information when the process concludes. 
Synairgen is entitled to receive circa 17% of Pharmaxis’ 
licence receipts/royalties, net of allowable expenses.

Strategic Report  
(continued)

Board changes 
In April 2019, Paul Clegg announced his intention to retire 
from the Board as a non-executive director after the 2019 
AGM in June. The Board thanks Paul for his significant 
contribution and advice to Synairgen over the last 10 
years and for his Chairmanship of the Remuneration and 
Nomination Committee. Iain Buchanan became the new 
Chairman of the Remuneration and Nomination Committee.

Key performance indicators (KPIs)

The Board considers that the most important KPIs are 
non-financial and relate to the progress of the scientific 
programmes which are discussed in the preceding section  
of this report. 

The most important financial KPIs are the planned R&D 
expenditure on the COPD trial and the cash position of the 
Group. The actual expenditure on the COPD trial was below 
budget and the closing cash position was ahead of budget. 
These are further described in the financial review below. 

Financial Review

The Financial Review should be read in conjunction with 
the consolidated financial statements of the Company and 
Synairgen Research Limited (together the ‘Group’) and the 
notes thereto on pages 29 to 45. The consolidated financial 
statements are presented under International Financial 
Reporting Standards as adopted by the European Union. 

The adoption of IFRS 16 ‘Leases’ has only had a limited impact 
on the Consolidated Statement of Financial Position as at  
31 December 2019 with the recognition of right-of-use assets 
(£0.26 million) and lease liability payables (£0.33 million). There 
was no impact on the 2018 primary statements presented.

The financial statements of the Company, set out on 
pages 46 to 49, are prepared in accordance with Financial 
Reporting Standard 101 Reduced Disclosure Framework. 

Statement of Comprehensive Income
The loss from operations for the year ended 31 December 
2019 was £4.82 million (2018: loss £4.13 million). There were no 
revenues for the year (2018: £0.11 million). The 2018 revenue 
comprised fee for service work in relation to the LOXL2 
programme, through our partnership with Pharmaxis Ltd.

Research and development expenditure for the year 
amounted to £3.46 million (2018: £3.23 million) and the 
majority of this expenditure was on running the IFN-beta 
Phase II clinical trial in COPD.

Other administrative costs for the year were £1.36 million  
(2018: £1.01 million), with the increase attributable to higher 
staff costs during the period. The tax credit for 2019 amounted 
to £0.91 million (2018: £0.80 million) and included £0.04 million 
in respect of prior periods. The loss after tax for 2019 was £3.89 
million (2018: loss of £3.30 million) and the basic loss per share 
amounted to 3.55p (2018: basic loss per share of 3.47p). 

Statement of Financial Position and cash flows
At 31 December 2019, net assets amounted to £2.25 million 
(2018: £6.03 million), including cash and bank deposits of 
£2.45 million (2018: £5.33 million). 

The principal elements of the £2.88 million decrease over the 
year ended 31 December 2019 (2018: £1.51 million decrease) 
in cash and bank deposits were:

•  Cash used in operations: £3.73 million (2018: £3.89 million); 

•  Research and development tax credits received:  

£0.84 million (2018: £0.07 million);

•  Capital expenditure on property, plant and equipment: 

£0.01 million (2018: £0.39 million); and

•  Share issue proceeds (net of costs): £nil (2018: £2.67 million).

The other significant changes in the statement of financial 
position were:

•  Net book value of property, plant and equipment reduced 

from £0.37 million to £0.30 million as we depreciated 
the bioMérieux multiplex PCR virus detection machines 
purchased in 2018 for use in the SG015 clinical trial;

•  Following the adoption of IFRS 16 (as discussed above) 

we recognised right-of-use assets in 2019 and at 
31 December 2019 the balance net of depreciation 
charged amounted to £0.26 million (2018: £nil). We also 
recognised the corresponding lease liabilities and at 
31 December 2019 the non-current liability element 
amounted to £0.13 million (2018: £nil) and the current 
liability element £0.20 million (2018: £nil); and

•  Trade and other payables increased from £0.78 million to 

£1.49 million, on account of higher accruals for clinical trial 
related activities and staff performance bonuses. 

Post year-end fundraising
£14 million (before expenses) was raised in March 2020 by the 
issue of 40 million ordinary shares at a price of 35p per share 
to fund the following activities:

•  COVID-19 clinical trial activity (£7 million);

•  Manufacture of SNG001 drug product and other supply 

c)  the need to foster the Company’s business relationships 

chain considerations (£4 million); and

with suppliers, customers and others;

•  Strengthened balance sheet for potential partnering 
discussions, working capital and fees (£3 million).

d)  the impact of the Company’s operations on the community 

and the environment;

Section 172 statement
For years beginning on or after 1 January 2019 companies 
quoted on AIM now have to include a Section 172(1) statement 
in the Strategic Report explaining how directors have had 
regard to the matters set out in Section 172(1).

Under Section 172(1) of the Companies Act 2006, a director 
of a company must act in the way he considers, in good faith, 
would be most likely to promote the success of the Company 
for the benefit of its members as a whole, and in doing so 
have regard (amongst other matters) to:

a)  the likely consequences of any decision in the long-term;

b)  the interests of the Company’s employees;

e)  the desirability of the Company maintaining a reputation 

for high standards of business conduct; and

f) 

the need to act fairly between members of the Company.

The directors acknowledge their duty under Section 172 of 
the Companies Act 2006 and consider that they have, both 
individually and together, acted in the way that, in good faith, 
would be most likely to promote the success of the Company 
for the benefit of its members as a whole.

The following table, in combination with the Corporate 
Governance Statement set out on pages 13 to 16 and the 
Company’s website (www.synairgen.com), sets out the 
framework of our engagement with key stakeholder groups. 

Our stakeholders

Material topics

How we engage

Investors
The Group continues to consume cash 
resources and remains dependent upon 
securing funding through share issues. It is 
therefore critical that we have shareholders 
who will continue to invest in the company  
over the longer term.

Employees
Synairgen has 14 employees (including 
executive directors) who are multi-skilled and 
most of them have worked for the Group 
for many years. They all play a key role in the 
business and it is vital that they all understand 
and support the key decisions taken in the 
running of the business.

University of Southampton
Synairgen is a spin-out company from the 
University and still maintains many links with 
it, which benefit both parties. The University 
is Synairgen’s landlord and certain intellectual 
property is licensed from it.

Suppliers
We have a number of key long-term suppliers 
who play an important part in our development 
programmes and it is important that we under-
stand their product/service development plans 
and they understand our needs.

Our stakeholders

Material topics

How we engage

Collaboration partners
Following our earlier collaboration with 
Pharmaxis, we maintain a 17% stake in the 
LOXL2 programme.

Customers (licensees)
Our customers are the large pharmaceutical 
and biotech companies who have the resources 
and infrastructure to take our products to 
market. It is therefore critical that we interact 
with these companies at an early stage to make 
sure we are developing a product which they 
may wish to license.

Community
We aim to develop therapeutics which 
pharmaceutical companies can sell to the 
community and it is therefore critical that there 
is an identified market need in the community.

Regulators
We work in a highly regulated sector and it is 
critical that we maintain full compliance with  
all appropriate regulations.

Principal decisions in 2019

Principal risks and uncertainties

We have considered the decisions taken by the Board which 
will have an impact on the longer-term performance and 
prospects for the Company. The Board believes that two 
decisions taken during the year fall into this category and  
were made with full consideration of both internal and 
external stakeholders.

•  The decision to initiate more clinical trial sites and enlarge 
the patient pool for the Group’s phase II trial of interferon 
beta in COPD.

•  The decision to commit resources to explore the potential 
for interferon beta in immuno-compromised patients. 

In addition, the Board keeps the Company’s finances under 
close scrutiny, seeking to ensure that it has sufficient capital 
resources to execute its business plan. During the year, the 
Board continually assessed whether additional funding would 
be required to complete the COPD trial (SG015).

The Board considers that the principal risks and uncertainties 
facing the Group may be summarised as follows:

•  Interferon beta Phase II trials fail to generate  

encouraging data
There can be no guarantee that the trials being conducted 
in COPD patients, hospitalised COVID-19 patients and 
home-based COVID-19 patients will generate data which 
merits further development expenditure in the programmes 
either by Synairgen or a licensee.

•  Impact of COVID-19 on the wider economy

Whilst the emergence of the COVID-19 pandemic has 
presented a very significant potential opportunity for the 
Group to develop a new indication for its interferon beta 
programme and the Group’s employees have been able to 
function effectively working from home or where required in 
the clinical and laboratory facilities, it remains unclear at this 
stage what the medium and long term impact will be on the 
wider economy and how this will affect the Group.

•  Interferon beta Phase II trial in COVID-19 patients at home 

overruns or is unable to randomise 120 patients
The Group is commencing a Phase II trial in COVID-19 
patients at home, which is seeking to randomise 120 
patients. The conclusion of the trial is dependent upon the 
rate at which such patients can be recruited into the trial, 
which will be determined by the success in being able to find 
such patients and the prevalence of COVID-19 in the coming 
months. Overrunning of the trial would result in extra costs 
to complete the trial, as a number of the monthly costs 
are fixed in nature. Inability to recruit the full patient target 
will reduce the chance of finding statistically significant 
outcomes.

At the date of this report recruitment activity is about to 
commence. The Group is continually monitoring the best 
recruitment options available and will also consider the 
benefits of opening additional sites. In the event that the 
COVID-19 infection rates reduce very substantially, the 
Group would consider whether it is best to finish the trial 
before the target 120 patients have been randomised.  

•  Ability to scale up interferon beta production

In the event of a positive read-out from the COVID-19 trials, 
there will potentially be a need to significantly increase 
production to maximise the commercial opportunity.  
The Group is currently exploring routes whereby the drug 
and delivery devices can be manufactured at scale.

•  Commercial risk

There can be no guarantee that the Group, or Pharmaxis, 
in the case of its LOXL2 programme in which the 
Group has a 17% share, will succeed in securing and 
maintaining the necessary contractual relationships 
with licensing partners for its programmes under 
development. Even if the programmes are successfully 
out-licensed and pharmaceutical products are brought 
to market by a partner, there is no guarantee that 
such products will succeed in the marketplace.

The Group seeks to reduce this risk by structuring 
its development programmes to meet the needs 
and requirements of its potential partners and by 
engaging with partners who have the appropriate 
experience, resource and interest to bring such 
pharmaceutical products to the global marketplace.

• Intellectual property risk

The commercial success of the Group depends on its 
ability to obtain patent protection for its pharmaceutical 

discoveries in the US, Europe and other countries and 
to preserve the confidentiality of its know-how. There 
is no guarantee that patent applications will succeed or 
be broad enough to provide protection for the Group’s 
intellectual property rights and exclude competitors 
with similar pharmaceutical products. The success of the 
Group is also dependent on non-infringement of patents, 
or other intellectual property rights, held by third parties. 
Competitors and third parties may hold intellectual property 
rights which the Group may not be able to license upon 
favourable terms, potentially inhibiting the Group’s ability 
to develop and exploit its own business. Litigation may 
be necessary to protect the Group’s intellectual property, 
which may result in substantial costs.

The Group seeks to reduce this risk by seeking patent 
attorney advice that patent protection will be available prior 
to investing in a project, by seeking patent protection where 
appropriate, and by minimising disclosure to third parties.

•  Competition risk

The Group’s current and potential competitors include 
pharmaceutical and biotechnology companies and 
academic institutions, many of whom have significantly 
greater financial resources than the Group. There can be no 
assurance that competitors will not succeed in developing 
products that are more effective or economic than any 
developed by the Group, or which would render the Group’s 
products non-competitive or obsolete. 

•  Funding risk

The Group continues to consume cash resources. Until the 
Group generates positive net cash inflows from successful 
out-licensing transactions and commercialisation of its 
products, it remains dependent upon securing funding 
through the injection of capital from share issues. The 
Group may not be able to generate positive net cash flows 
in the future or attract such additional funding required at 
all, or on suitable terms. In such circumstances, the Group’s 
discovery and development programmes may be delayed 
or cancelled and the business operations curtailed.

The Group seeks to reduce this risk through tight financial 
control, prioritising programmes which will generate the 
best returns, and keeping shareholders informed on 
progress. Post period-end, the Group raised £14 million 
(before expenses) to fund its COVID-19 activities and 
strengthen its balance sheet.

•  Dependence on Founders, senior management  

and key staff
The Founders and certain members of staff are highly 
skilled scientists and clinicians. The Group has deliberately 
pursued a lean headcount policy to conserve financial 
resources. Failure to continue to attract and retain such 
individuals could adversely affect operational results. 
The setting up and running of two COVID-19 clinical trials 
whilst in a “lockdown” environment has placed a significant 
additional burden on the existing headcount.

The Group seeks to reduce this risk by recruiting 
additional staff/contractors and additionally appropriate 
incentivisation of staff through participation in long term 
equity incentive schemes.

•  Brexit

The UK left the European Union in January 2020 and 
is now in a transition period until the end of 2020. 

It remains unclear what the final outcome of the transition 
process will be. In the short term our key focus is upon 
completing the Phase II clinical trials during 2020 and we 
have secured adequate stocks of drug and consumable 
items to complete them at our trial sites which are all 
located in the UK. 

•  Cyber attack or IT systems failure

The Group is at risk of cyber attack or IT systems failure, 
which would cause operational harm, including potential 
theft or loss of data.

The Group seeks to minimise this risk by retaining 
the services of external IT advisers and pursuing 
suitable back-up and security policies.

Summary and Outlook

During the calendar year 2019 we made good progress in the trial 
of our wholly-owned asset SNG001 in COPD. The emergence of 
SARS-CoV-2 has caused us to pause the COPD trial and to divert 
our expertise and investment to addressing the more pressing 
COVID-19 pandemic. Knowing that a broad spectrum antiviral 
agent delivered directly to the lungs may prevent the development 
of lower respiratory tract illness or accelerate the recovery of 
patients already hospitalised, we have raised additional funding 
of £14 million, which has enabled us to successfully initiate a 
trial of approximately 220 patients with COVID-19, some 100 of 
whom are in the hospital environment with severe respiratory 
symptoms, with a further 120 patients who will be dosed in the 
home environment upon early signs of COVID-19. Our staff and 
our key suppliers in both the UK and overseas have been able to 
continue working through lockdown. Data from the hospital trial 
will read out during the summer, and, if positive, the Company will 
work closely with regulators to determine an expeditious route 
to securing approval for SNG001, a treatment we believe could 
play an important role in addressing the current COVID-19 crisis 
and similar viruses in the future. In parallel the Company is now 
working with manufacturers to scale up for potential demand 
for SNG001. The outlook for the business is positive and we look 
forward to updating the market on further progress in due course.

Corporate Governance Statement

The Board is accountable to the Company’s shareholders 
for good corporate governance and it is the objective of the 
Board to attain a high standard of corporate governance. 
As Chairman, it is my primary responsibility to lead the 
Board effectively and to oversee the adoption, delivery and 
communication of the Company’s corporate governance model. 

In September 2018 the Board adopted the Quoted Companies 
Alliance Corporate Governance Code (QCA Code). On 
our website (www.synairgen.com/investors/corporate-
governance-statement/) we set out how we comply with 
the 10 principles of the QCA Code. The following sections 
of the Corporate Governance Statement explain how the 
QCA Code is applied by the Company. During 2019 we 
undertook another formal Board performance review, which 
identified two areas for improvement during 2020.

Board of Directors
On 31 December 2019 the Board of directors (the ‘Board’) 
consisted of a non-executive Chairman (Simon Shaw), three 
executive directors (Richard Marsden, Dr Phillip Monk 
and John Ward), and three non-executive directors (Iain 
Buchanan, Dr Bruce Campbell and Prof. Stephen Holgate). 
Paul Clegg retired from the Board as a non-executive 
director after 10 years of service on 3 June 2019.

The responsibilities of the non-executive Chairman and the 
Chief Executive Officer are clearly divided.  The non-executive 
directors bring relevant experience from different backgrounds 
and receive a fixed fee for their services and reimbursement 
of reasonable expenses incurred in attending meetings. 

Brief curriculum vitae details about the directors are given on 
page 11. The key experience, skills, qualities and capabilities 
that each director brings to the Board are summarised below:

Simon Shaw
Simon is an experienced public company director, having fulfilled 
both the roles of Chief Financial Officer and Chief Operating Officer 
for listed companies. He has life science company experience 
and in addition to his skills as a Chairman contributes strong 
financial and corporate finance skills. As an executive director of a 
FTSE 250 company he keeps his skill set in these areas up to date.

Richard Marsden
Richard has worked in a number of roles within the life sciences 
sector and has experience of sales and marketing, clinical 
trials, project management, business development and 
general management. He is actively involved in the design 
and management of clinical trials and leads the Company’s 
business development activities. He maintains and develops 
his skill sets in these areas by regular interaction with the 
Company’s expert advisers and key opinion leaders (KoLs).

Dr Phillip Monk
Phillip is a leading scientist in respiratory biology, with experience 
of managing teams of scientists and taking drugs through pre-
clinical and early clinical trials. His particular contribution to the 
Board is championing the identification and management of new 
opportunities up to the clinical stage, and maximising value from 
early stage clinical trials, particularly with reference to biomarker 
and statistical analysis. Phill regularly interacts with expert 
advisers/KoLs and attends key relevant medical conferences.

John Ward
John is a Chartered Accountant who has worked for 23 years 
as Finance Director and Company Secretary in the life sciences 
sector, with experience gained in private and quoted companies. 
From his time at Price Waterhouse he also has corporate 
finance experience. He keeps his skill set up to date by attending 
appropriate courses run by accountancy firms, the ICAEW and ICSA.

Iain Buchanan
Iain has 40 years’ management experience in the pharmaceutical 
and biotech sector. Iain keeps his skill set up to date through 
his involvement with a number of other life sciences boards.

Dr Bruce Campbell
Bruce has 50 years’ drug development experience. He has 
particular expertise in pre-clinical development. Bruce keeps 
his skill set up to date through his involvement with a number of 
other life sciences companies either as a director or consultant.

Prof. Stephen Holgate
Stephen is a leading academic in respiratory medicine, combining 
an outstanding knowledge of base and clinical science. He has 
experience of working with many pharmaceutical companies 
and guides the Board on developments in the respiratory sector. 
Stephen keeps up to date through his ongoing involvement with 
many industry and government-related organisations as an advisor.

All seven members of the Board bring relevant sector experience 
in life sciences. Four members of the Board have public markets 
experience from other companies. The Board has expertise 
in the following key areas: public markets; discovery and pre-
clinical respiratory projects, clinical development, business 
development/licensing and finance. The Board believes that 
its blend of relevant experience, skills and personal qualities 
and capabilities is sufficient to enable it to successfully execute 
its strategy. The Board is still composed solely of males 
and recognises this gender imbalance.  In due course, the 
Board will look to amend its composition appropriately.

John Ward fulfils the roles of Finance Director and Company 
Secretary. The Board considers that at this stage of the Company’s 
development this is an appropriate and cost-effective modus 
operandi. It will continue to monitor when it will be necessary 
and appropriate to separate the roles. The Company Secretary 
reports directly to the Chairman on governance matters.

Non-executive directors are required to attend 6 scheduled 
bi-monthly Board meetings (Scheduled Board meetings) 
and committee or Scientific Advisory Board meetings. Non-
executive directors are required to be available at other 
times as required for face-to-face and telephone meetings 
with the executive team. All members of the executive 
team work for the Company on a full-time basis and have 
no non-executive directorships with other companies.

The Board notes that its directors have been in post for more than 
nine years but considers that they remain functionally independent, 
in that they remain fully committed to promoting the success 
of the Company for the benefit of shareholders as a whole.

The Board also notes that one of its non-executive directors 
was granted options in 2010, which will expire in 2020. The 
practice of granting non-executive directors options has 
now ceased and the Board considers that the holding of 
these options (which represents less than 0.3% of the 
issued share capital at 31 December 2019) does not 
compromise the independence of the director concerned.

With effect from the 2019 AGM and on an on-going 
basis, the Board puts all directors up for re-election on 
an annual basis to enable shareholders to confirm their 
support that the directors remain independent.

The Company does not have a Senior Independent 
Director and we believe that this is appropriate at 
this stage of the Company’s development.

The Board retains full and effective control of the Group. This 
includes responsibility for determining the Group’s strategy and 
for approving budgets and business plans to fulfil this strategy. 
There are a number of Scheduled Board meetings and the Board 
also meets on any other occasions it considers necessary. During 
the year ended 31 December 2019, the Board met six times for 
Scheduled Board meetings, with each member attending as follows:

Director

In addition there was one other meeting, to which Board members 
were invited, during the year.

It is the duty of the Chairman to ensure that all directors are 
properly briefed on issues arising at Board meetings. Prior to each 
Board meeting, directors are sent an agenda and Board papers 
for each agenda item to be discussed. Additional information is 
provided when requested by the Board or individual directors.

The Company Secretary is responsible to the Board for ensuring 
that Board procedures are followed and that the applicable rules 
and regulations are complied with. All directors have access to the 
advice and services of the Company Secretary, and independent 
professional advice, if required, at the Company’s expense. Removal 
of the Company Secretary would be a matter for the Board.

Board performance
A Board evaluation process led by the Chairman took place in 
December 2019. All of the directors completed a questionnaire 
about the effectiveness of the Board and the results were compiled 
on an anonymous basis by the Company Secretary. The Board 
reviewed the outcome of the questionnaire and noted that some of 
the areas identified, such as succession planning, were not feasible 
at this stage of the Company’s evolution. However a number of 
refinements in working practices were identified as a result of this 
exercise with regards to improvement of Board meeting efficiency 
and risk management systems and have been scheduled for 
implementation in 2020.

Corporate Governance Statement
(continued)

Also during December 2019, a review of the Chairman’s 
performance over the last year was carried out by the completion 
of a questionnaire by other Board members. It is intended that 
this internal review will be carried out on an annual basis.

Board committees
As appropriate, the Board has delegated certain responsibilities to 
Board committees.

Audit Committee
The Audit Committee currently comprises Simon Shaw 
(Chairman), Iain Buchanan and Dr Bruce Campbell. Whilst 
it is not normal in larger companies for the chairman of 
the Company to chair the Audit Committee, the Company 
considers it appropriate for Simon Shaw to be Chairman as 
he is considered to have the most significant, recent and 
relevant financial experience of the non-executive directors. 

The committee has primary responsibility for ensuring that the 
financial performance of the Group is properly measured and 
reported on and it reviews the interim financial information 
and annual financial statements before they are submitted 
to the Board. The committee reviews accounting policies and 
material accounting judgements. The committee also reviews, 
and reports on, reports from the Group’s auditors relating to 
the Group’s accounting controls. It makes recommendations to 
the Board on the appointment of auditors and the audit fee. The 
committee monitors the scope, results and cost-effectiveness 
of the audit. It has unrestricted access to the Group’s auditors. 
In certain circumstances it is permitted by the Board for the 
auditors to supply non-audit services (in the provision of tax 
advice, or on specific projects where they can add value).

During 2019, the committee met four times. Simon Shaw and  
Iain Buchanan attended all four meetings and Dr Bruce Campbell 
attended three meetings. The Audit Committee Report is detailed 
on page 22.

Remuneration and Nomination Committee
The Remuneration and Nomination Committee currently 
comprises Iain Buchanan (Chairman), Dr Bruce Campbell and 
Simon Shaw. Iain Buchanan became Chairman of the committee 
on 3 June 2019 when Paul Clegg retired from the Company as a 
non-executive director. The committee is responsible for making 
recommendations to the Board on remuneration policy for 
executive directors and the terms of their service contracts, with 
the aim of ensuring that their remuneration, including any share 
options and other awards, is based on their own performance 
and that of the Group generally. The committee administers the 

Long-Term Incentive Plan, the staff share option scheme and the 
Qualifying Non-Employee Option Scheme and approves grants 
under all three schemes. It also advises on the remuneration 
policy for the Group’s employees. The committee is responsible 
for all senior appointments that are made within the Group.

During 2019, the committee met three times with all 
members attending. The Directors’ Remuneration 
Report is detailed on pages 17 to 21.

Scientific Advisory Board
The Company established a Scientific Advisory Board (‘SAB’) 
in 2016. The purpose of the SAB is to provide strategic advice 
and input on scientific aspects of Synairgen’s research and 
development projects.

The SAB currently comprises Dr Phillip Monk (Chairman), Iain 
Buchanan, Dr Bruce Campbell, and Synairgen’s three academic 
founders (Professors Stephen Holgate, Donna Davies and Ratko 
Djukanovic). Other external experts and Synairgen employees 
attend meetings as required. Dr Bruce Campbell is responsible for 
feeding back the outputs from the SAB to the Company’s Board.

Business model and strategy
As detailed in the Strategic Report on page 3, Synairgen’s 
strategy is to identify novel drug targets, progress them 
through early stage clinical trials and license them to 
partners to advance through to commercialisation. The 
key challenges in execution are set out in the section of the 
Strategic Report entitled Principal risks and uncertainties. 

Corporate culture
Synairgen is a biotechnology company focussed on developing new 
respiratory therapies which will make a difference to people’s lives.  
Our core values to achieve this are:

•  Passion – to demonstrate a passion for delivering high  

quality service

•  Professionalism – to demonstrate courtesy, honesty and 

responsibility when dealing with individuals or others in the 
business environment

•  Collaboration – to work effectively and inclusively with individuals, 

institutions, or other companies in the business environment

•  Experience – to demonstrate knowledge and skills in the  

business environment

•  Approachability – to be accommodating, friendly and  

transparent when working with others

These matters are reviewed annually during staff appraisals.

Investor relations
The directors seek to build a mutual understanding of objectives 
between the Company and its shareholders by meetings with 
major institutional investors and analysts after the Company’s 
preliminary announcement of its year-end results and its interim 
results. The Company also maintains investor relations pages 
on its website (www.synairgen.com) to increase the amount of 
information available to investors. 

There is an opportunity at the Annual General Meeting for 
individual shareholders to question the Chairman, the Chairmen 
of the Audit and Remuneration and Nomination committees, 
and the executive directors. Notice of the meeting is sent 
to shareholders at least 21 clear days before the meeting. 
Shareholders are given the opportunity to vote on each separate 
issue.  The Company counts all proxy votes and indicates the 
level of proxies lodged on each resolution, after it has been 
dealt with by a show of hands. Details of the proxies lodged 
are also published on the Company’s website. Details of the 
resolutions and explanations thereto are included with the notice, 
including any special arrangements necessitated by COVID-19.

Internal control and risk management
The directors are responsible for establishing and maintaining the 
Group’s system of internal control and reviewing its effectiveness. 
The system of internal control is designed to mitigate, rather than 
eliminate, the risk of failure to achieve business objectives and 
can only provide reasonable but not absolute assurance against 
material misstatement or loss.

The main features of the internal control system are as follows:

•  a control environment exists through the close management of 

the business by the executive directors. The Group has a defined 
organisational structure with delineated approval limits. Controls 
are implemented and monitored by personnel with the necessary 
qualifications and experience;

•  a list of matters reserved for board approval;

•  monthly management reporting and analysis of variances;

•  regular financial reforecasts;

•  financial risks for each major transaction are identified and 

evaluated by the Board; and

•  standard financial controls operate to ensure that the assets of 
the Group are safeguarded and that proper accounting records 
are maintained.

The Company maintains a summary risk register which is 
reviewed by the Board on an annual basis. The principal risks 
and uncertainties facing the Group, with mitigation strategies, 
are set out in the Strategic Report on pages 7 to 9. Project risk 
management is continually evaluated by weekly project meetings 
and other management tools. IT risk is covered at bi-annual 
meetings with external IT advisers. An annual Health and Safety 
report is prepared for the Board.

Directors’ Remuneration Report

In September 2018 the Company adopted the QCA Corporate 
Governance Code which includes the requirement to prepare a 
remuneration committee report. This report includes and complies 
with the disclosure obligations of the AIM Rules.

The previous salary and benefit review took effect from  
1 January 2019, at which point the executive directors’  
salaries were increased by 2% (in line with or below the  
level awarded to staff generally).  

Remuneration Committee
The Company’s remuneration policy is the responsibility of the 
Remuneration and Nomination Committee (the ‘Committee’), 
which was established in October 2004. The terms of 
reference of the Committee are outlined in the Corporate 
Governance Statement on page 15. The members of the 
Committee are Iain Buchanan (Chairman), Dr Bruce Campbell 
and Simon Shaw. Paul Clegg was Chairman of the Committee 
until his retirement from the Board on 3 June 2019, after 
which Iain Buchanan joined the Committee as Chairman.

The Committee, which is required to meet at least twice a 
year, met three times during the year ended 31 December 
2019 and considered the pay of the executive directors and 
ensured it understood pay arrangements more broadly 
across the Group. The Chief Executive Officer and certain 
executives may be invited to attend meetings of the Committee 
to assist it with its deliberations, but no executive is present 
when his or her own remuneration is discussed.

During the year, the Committee has been advised on director 
remuneration by its retained independent remuneration adviser, 
FIT Remuneration Consultants LLP. No other advice has been 
provided to the Group by this firm during the year.

Remuneration policy
(i) Executive remuneration
The Committee has a duty to establish a remuneration policy 
which will enable it to attract and retain individuals of the highest 
calibre to run the Group. Its policy is to ensure that the executive 
remuneration packages of executive directors and the fee of 
the Chairman are appropriate given performance, scale of 
responsibility, experience, and consideration of the remuneration 
packages for similar executive positions in companies it considers 
to be comparable. Packages are structured to motivate executives 
to achieve the highest level of performance in line with the best 
interests of shareholders. A significant element of the total 
remuneration package, in the form of bonus and Long Term 
Incentive Plan (‘LTIP’) awards, is performance driven. 

Executive remuneration currently comprises a base salary, an 
annual performance-related bonus, LTIP participation, a pension 
contribution to the executive director’s individual money purchase 
scheme or, where it is not permitted under HMRC rules, as a salary 
supplement after deducting an amount to reflect employer’s NICs 
to ensure that the overall cost to the employer is not increased  
(at 9% of base salary) and typical benefits including family  
private health cover, permanent health and life assurance. 

Salaries and benefits have been reviewed with effect from 
1 January 2020, taking into account Group and individual 
performance, external benchmark information and 
internal relativities. As a consequence of the 2020 review, 
executive director salaries were, again, increased by 2%, 
which was below the level awarded to staff generally.

Executive directors are also rewarded for improvements in the 
performance of the Group sustained over a period of years in 
the form of Long Term Incentive Plan share awards granted on a 
discretionary basis by the Committee.

Directors’ remuneration for the year ended 31 December 2019 is 
set out on page 20 and 21 of this document.

(ii) Chairman and non-executive director remuneration
During the year ended 31 December 2019, the Chairman and the 
non-executive directors received a fixed fee of £25,000 per annum. 
The fixed fee covers preparation for and attendance at meetings of 
the full Board and committees thereof. A fee of £5,000 per annum 
was also paid for chairing each of the audit and remuneration 
committees. The Chairman and the executive directors are 
responsible for setting the level of non-executive director 
remuneration. The non-executive directors are also reimbursed  
for all reasonable expenses incurred in attending meetings.

The remuneration paid to the Chairman and the non-executive 
directors has remained unchanged since 2009 and 2014 
respectively. In April 2020, a benchmarking of the remuneration 
of the Chairman and the non-executive directors was undertaken. 
As a result of this, the fee payable to the Chairman was increased 
to £45,000 per annum with effect from 1 January 2020. The fixed 
fee for the non-executive directors remains unchanged at £25,000 
and a fee of £5,000 will continue to be paid to non-executive 
directors who chair either the audit or remuneration committees. 
The Chairman has waived his entitlement to the fee for chairing the 
audit committee. 

(iii) Annual bonus plan 
The Company operates a discretionary bonus scheme for executive 
directors for delivery of exceptional performance against pre-set 
relevant corporate objectives, which are subject to malus and 
clawback provisions. As reported last year in respect of 2018, the 
scheme for 2018 involved a range of operational milestone targets 
linked to the interferon beta programme, the LOXL2 programme 
and potential new opportunities. Again, as reported last year 
in respect of 2018, the Committee noted that, while significant 
progress had, again, been made against these milestones in 
2018, as the Company had not received any revenues from 
these achievements, the executive directors requested that the 
Committee defer a final decision regarding such bonuses until such 
a commercial benefit is delivered.

Following the significant progress made since then, the Committee 
determined that the 2018 bonus targets should now be assessed 
rather than held over again. It determined that the scorecard was 
achieved as to 55%. This was wholly based on achievement in 2018.

The Committee also assessed performance against the scorecard 
for 2019. This included supporting the LOXL2 programme, 
recruitment targets for the interferon beta COPD trial, commencing 
another study of interferon beta, announcement of a new programme 
and investor relations targets. The Committee determined that 
this was met as to 42% noting, in particular, full achievement of the 
stretch target of entering 286 patients into the pool by the end of 
September 2019 (which had been given a 40% weighting).

Bonuses in respect of 2018 and 2019 will be paid in Q2 2020.

(iv) Equity-based incentive schemes
The Committee strongly believes that long term equity-based 
incentive schemes increase the focus of employees in improving 
Group performance, whilst at the same time providing a strong 
incentive for retaining and attracting individuals of a high calibre.

Long Term Incentive Plan (LTIP)
The Synairgen Long Term Incentive Plan, comprising conditional 
(performance-related) share awards (technically structured as 
nominal cost options pursuant to which participants must pay  
1p per share on the exercise of their awards) is the sole on-going  
long-term incentive vehicle for executive directors. 

Senior executives and other employees may be granted an award, 
which will normally vest if demanding performance conditions are 
achieved over a three-year period and if the grantee remains an 
employee of the Group. 

Grants under the LTIP in any financial year are capped  
at a maximum of 100% of base salary. 

As indicated in last year’s report, an LTIP award was made in 
April 2019 during the six week period following the preliminary 
announcement of the results for the year ended 31 December 
2018, with each of Richard Marsden, Phillip Monk and John Ward 
being granted awards over shares worth approximately 51% of 
salary (the Committee approved an award over shares worth 65% 
of salary but determined that this should be assessed on a higher 
than actual share price (the 16p price at which funds were raised 
in October 2018) so 51% represents the actual grant multiple), with 
performance conditions as set out below. 

The Committee intends to make an LTIP award (the 2020 award) 
during the six week period following the preliminary announcement 
of the results for the year ended 31 December 2019, with each 
of Richard Marsden, Phillip Monk and John Ward being granted 
awards over shares worth up to 100% of salary with performance 
conditions similar to the 2019 LTIP award. The Committee’s long-
term policy has been to grant executive directors an award over 
shares worth one times salary at grant. However, that has not 
been feasible in recent years due a combination of close period 
constraints and management of the dilution limits. The Committee 
noted that the current share price is approximately 3 times the 
share price used for the 2019 grant and that it was, therefore, 
now feasible and appropriate to award shares in line with the 
shareholder approved policy level of 100% of salary.

Executive directors are expected to retain no fewer than 50% of 
shares acquired upon vesting of awards under the LTIP, net of 
shares sold to pay taxes, until such time as, in combination with  
any other shares the executives may have acquired, they hold 
shares with a value equivalent to 100% of base salary. 

All awards will lapse at the end of the applicable performance 
period to the extent that the applicable performance criteria 
conditions have not been satisfied with no opportunity for 
retesting.  In the event of a good leaver event or a change of control 
of the Company, the LTIP awards may vest early, but only to the 
extent that, in the opinion of the Committee, the performance 
conditions have been satisfied at that time. The awards will 
generally also be subject to a time pro-rated reduction to reflect 
the reduced period of time between the grant of the awards and 
the time of vesting although this reduction may not be applied in 
certain cases.

Performance conditions for the 2018 and 2019 LTIP awards
The performance conditions for both awards were the same. 
The awards are subject to two conditions. Firstly, awards will 
only vest to the extent that the percentage increase in the 
total shareholder return (‘TSR’, being the return earned by a

the share price and assuming re-investment of any dividends in 
more shares at the prevailing price on the relevant ex-dividend

equal or greater than the percentage increase in the techMARK

Secondly, no award will vest unless the average annual growth in 
the TSR of the Company over the performance period is equal to or 
greater than RPI plus 2% or, for more than 75% of an award to vest, 
annual average TSR must exceed RPI by at least 5% rather than 2%.

(v) Service contracts and letters of appointment
The executive directors have entered into service agreements 
which can be terminated on six months’ notice by either party.  

During the year ended 31 December 2019, the executive directors 
did not hold any non-executive directorships with other companies.

The Chairman and non-executive directors have entered into 
letters of appointment for an initial fixed period of twelve months, 
which renew automatically for a further twelve month period on 
the anniversary of commencement. The appointment can be 
terminated on three months’ notice by either party.

Directors’ interests in share options
The interests of directors in share options over ordinary shares during the year were as follows:

These awards were granted under a legacy plan. The exercise of the options awarded in June 2010 (which vested in 2013) is subject to  
the rules of the scheme. The option granted to Mr Clegg lapsed without being exercised on its 10th anniversary.

There were no other options granted to directors or which were exercised or lapsed during the year. 

The mid-market price of the Company’s shares at 31 December 2019 was 5.875p. During the year then ended, the mid-market price  
ranged from 5.875p to 18.00p. On 22 May 2020 the closing price was 51p.

Note 1. Awards normally lapse on the tenth anniversary of grant. Due to close period constraints, it was not feasible for the executives to exercise their 2009 awards and  
the Committee agreed to extend the exercise window until the end of 2020.

Note 2. The Company issued 40,000,000 new shares pursuant to a placing on 30 March 2020 and 15 April 2020. While this would have permitted the Committee to adjust 
the shares subject to awards using the HMRC established TERPS formulae (which would have increased the shares subject to awards by approximately a further one-third), 
the Committee felt that this was not appropriate as the placing was offered on a non-pre-emptive basis.

Directors’ Remuneration Report  
(continued)

Report of the Audit Committee  

for the year ended 31 December 2019

(i)  Richard Marsden was the highest paid director during the years ended 31 December 2019 and 2018. He did not exercise any options during either year. 

(ii)  Paul Clegg retired as a non-executive director on 3 June 2019. He received no payments for loss of office.

(iii)  The Company permits employees, including executive directors, to change their pension provision through an election under a flexible benefits arrangement.  

The reported numbers are before any personal elections.

(iv)  As explained on page 18, the executive directors were also awarded past due bonuses in respect of 2018; in 2019, the Committee had deferred a decision on  

such bonuses so no bonus was included in the 2018 report. The 2018 bonuses were £102,000, £74,000 and £80,000 in respect of Richard Marsden, Phillip Monk  
and John Ward.

In respect of key management personnel, for the year ended 31 December 2019, the total share-based payment amounted to £85,000  
(2018: £78,000) and total social security costs were £126,000 (2018: £62,000).  

By order of the Board

Iain Buchanan 
Chairman of the Remuneration and Nomination Committee

25 May 2020

BDO, the Company’s auditors, were present at all meetings.  
John Ward, the Company’s Finance Director, was present at all 
meetings except for when his performance was being discussed  
by the Committee.

Auditor independence
As set out in the Corporate Governance Statement on page 15,  
in certain circumstances it is permitted by the Board for the 
auditors to supply non-audit services (in the provision of tax advice, 
or on specific projects where they can add value). The Committee 
has approved and monitored the application of this policy in order 
to safeguard auditor objectivity and independence. The overall 
fees paid to the auditors for tax advice during the year (as detailed 
in note 4 to the Financial Statements) amounted to £7,000 and in 
relation to a Group audit fee of £35,000 are not deemed to be of 
such significance to them as to impair their independence. 

Internal audit function
The Group does not have an internal audit function, 
but the Committee considers that this is appropriate, 
given the size and relative lack of complexity of the 
Group at this stage in its development. The Committee 
keeps this matter under review annually. 

Simon Shaw 
Chairman of the Audit Committee

25 May 2020

Constitution and membership
The Audit Committee (the ‘Committee’) has primary responsibility 
for ensuring that the financial performance of the Group 
is properly measured and reported on. It was established 
in October 2004 and its terms of reference are outlined 
in the Corporate Governance Statement on page 15. 

The members of the Committee during the year under review and 
at the date of this report are Simon Shaw (Chairman), Iain Buchanan 
and Dr Bruce Campbell. Whilst it is not normal in larger companies 
for the chairman of the Company to chair the Audit Committee, 
the Company considers it appropriate for Simon Shaw to be 
Chairman as he is considered to have the most significant, recent 
and relevant financial experience of the non-executive directors.

Matters covered by the Committee
The Committee, which is required to meet at least twice a year, 
met four times during the year ended 31 December 2019,  
with Simon Shaw and Iain Buchanan attending all meetings  
and Bruce Campbell attending three meetings, and covered 
the following matters:

•  February 2019: audit completion meeting for the 2018 

year-end audit, including review of the valuation model to 
support Synairgen plc’s investment in Synairgen Research 
Limited, review of the financial forecast to support the 
Group’s ability to account on a going concern basis, review 
of the auditor’s report on the audit, and review of the annual 
report.

•  July 2019: planning meeting for the 2019 interim review, 

including agreement of scope, materiality, areas of focus and 
fees. The Committee also reviewed the impact of adoption 
of IFRS 16 Leases.

•  September 2019: interim report completion meeting 

for 2019, including review of report from the Company’s 
auditors.

•  December 2019: planning meeting for the 2019 year-end 

audit, including agreement of audit scope, materiality, areas 
of audit focus, audit fees and auditor independence.

The Committee also met in May 2020 for the audit completion 
meeting for the 2019 year-end audit including reviews of: the 
valuation model to support Synairgen plc’s investment in Synairgen 
Research Limited; the financial forecast to support the Group’s 
ability to account on a going concern basis, including the potential 
impact of COVID-19; the implementation of IFRS 16 accounting;  
the auditor’s report on the audit; and the annual report.

Directors’ Report

The directors present their report and the audited financial 
statements for Synairgen plc (the ‘Company’) and its subsidiary 
(together the ‘Group’) for the year ended 31 December 2019. 

The review of future developments is covered in the Outlook 
section of the Strategic Report. Details of directors’ remuneration 
and share options are given in the Directors’ Remuneration Report.

Research and development
During the year ended 31 December 2019, the Group 
has invested £3,460,000 (2018: £3,232,000) in research 
and development activities and a review of this 
expenditure is included in the Strategic Report.

Post balance sheet event
Post year-end, COVID-19 developed into a global pandemic.  
As described in the Strategic Report, the Group is now evaluating 
SNG001 in clinical trials of COVID-19 patients. As set out in note 21 
to the consolidated financial statements on page 45, post year-
end, the Company raised £14 million (before expenses) to fund 
its COVID-19 related activities and strengthen its balance sheet. 

Going concern
The directors have prepared financial forecasts to estimate 
the likely cash requirements of the Group over the next twelve 
months, given its stage of development and lack of recurring 
revenues. In preparing these financial forecasts, the directors 
have made certain assumptions with regards to the timing and 
amount of future expenditure over which they have control. The 
directors have attempted to take a prudent view in preparing 
these forecasts, recognising the inherent variability in costs of 
the ongoing clinical trials of SNG001 in COVID-19 patients. 

COVID-19 impacted the Group in a number of ways. The 
Phase II study in COPD was paused in March 2020 with 109 of 
the planned 120 patients randomised. An unplanned interim 
analysis is now being undertaken. The potential therapeutic 
benefits of interferon beta for patients with COVID-19 is now 
being explored in two clinical trials. The impact of lockdown 
and the challenge of commencing two new trials in a very 
short timescale has placed a significant burden on staff, whose 
response has been outstanding. With the exception of clinical 
staff who are working on the COVID-19 clinical trials and a small 
number of laboratory staff, all other staff have worked from 
home and communications have been facilitated by conference 
calls and videoconferencing. Key suppliers have also continued 
working during lockdown and this has not materially impeded 
on our ability to commence the trials in COVID-19 patients. Our 
clinical staff who are working in the hospital facility are issued 
with appropriate PPE, in accordance with NHS guidelines.

After due consideration of these forecasts and current cash 
resources, the directors consider that the Company and the Group 
have adequate financial resources to continue in operational 
existence for the foreseeable future (being a period of at least 
twelve months from the date of this report), and for this reason, the 
financial statements have been prepared on a going concern basis.

Treasury policy and financial risk management
The Group’s treasury policy and financial risk management is set 
out in note 17 to the financial statements on page 42.

Dividends
The directors do not propose the payment of a dividend.

Statement of Directors’ responsibilities in respect  
of the Annual Report and the Financial Statements

Independent Auditor’s Report 
to the members of Synairgen plc

The directors are responsible for keeping adequate accounting 
records that are sufficient to show and explain the Group’s and 
Company’s transactions and disclose with reasonable accuracy 
at any time the financial position of the Group and the Company 
and enable them to ensure that the financial statements comply 
with the requirements of the Companies Act 2006. They are 
also responsible for safeguarding the assets of the Group and 
the Company and hence for taking reasonable steps for the 
prevention and detection of fraud and other irregularities.

Website publication
The directors are responsible for ensuring the annual report 
and financial statements are made available on a website. 
Financial statements are published on the Group’s website in 
accordance with legislation in the United Kingdom governing the 
preparation and dissemination of financial statements, which 
may vary from legislation in other jurisdictions. The maintenance 
and integrity of the Group’s website is the responsibility of 
the directors. The directors’ responsibility also extends to the 
ongoing integrity of the financial statements contained therein. 

By order of the Board 

John Ward 
Company Secretary

25 May 2020

The directors are responsible for preparing the annual report  
and the financial statements in accordance with applicable law  
and regulations. 

Company law requires the directors to prepare financial 
statements for each financial year. Under that law the directors 
have elected to prepare the Group financial statements in 
accordance with International Financial Reporting Standards 
(‘IFRSs’) as adopted by the European Union and the Company 
financial statements in accordance with United Kingdom 
Generally Accepted Accounting Practice (United Kingdom 
Accounting Standards and applicable law). Under company law 
the directors must not approve the financial statements unless 
they are satisfied that they give a true and fair view of the state 
of affairs of the Group and Company and of the profit or loss 
of the Group for that period. The directors are also required to 
prepare financial statements in accordance with the rules of the 
London Stock Exchange for companies trading securities on AIM.  

In preparing these financial statements, the directors are  
required to:

•  select suitable accounting policies and then apply  

them consistently;

•  make judgements and accounting estimates that are  

reasonable and prudent;

•  state whether the Group financial statements have been 

prepared in accordance with IFRSs as adopted by the European 
Union and the Company financial statements in accordance  
with United Kingdom Generally Accepted Accounting Practice 
(United Kingdom Accounting Standards and applicable law), 
subject to any material departures disclosed and explained  
in the financial statements; and

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

Opinion 
We have audited the financial statements of Synairgen plc (the 
‘Parent Company’) and its subsidiaries (the ‘Group’) for the year 
ended 31 December 2019 which comprise the Consolidated 
Statement of Comprehensive Income, Consolidated Statement of 
Changes in Equity, Consolidated Statement of Financial Position, 
Consolidated Statement of Cash Flows, Parent Company Balance 
Sheet, Parent Company Statement of Changes in Equity and notes 
to the Consolidated and Parent Company financial statements, 
including a summary of significant accounting policies.

The financial reporting framework that has been applied in the 
preparation of the Group financial statements is applicable 
law and International Financial Reporting Standards (IFRSs) 
as adopted by the European Union. The financial reporting 
framework that has been applied in the preparation of the 
Parent Company financial statements is applicable law and 
United Kingdom Accounting Standards, including Financial 
Reporting Standard 101 Reduced Disclosure Framework 
(United Kingdom Generally Accepted Accounting Practice).

In our opinion: 

•  the financial statements give a true and fair view of the state  

of the Group’s and of the Parent Company’s affairs as at  
31 December 2019 and of the Group’s loss for the year  
then ended;

•  the Group financial statements have been properly prepared 
in accordance with IFRSs as adopted by the European Union;

•  the Parent Company financial statements have been 

properly prepared in accordance with United Kingdom 
Generally Accepted Accounting Practice; and

•  the financial statements have been prepared in accordance 

with the requirements of the Companies Act 2006.

Basis for opinion
We conducted our audit in accordance with International 
Standards on Auditing (UK) (ISAs (UK)) and applicable law.  
Our responsibilities under those standards are further  
described in the Auditor’s responsibilities for the audit of the 
financial statements section of our report. We are independent 
of the Group and the Parent Company in accordance with the 
ethical requirements that are relevant to our audit of the financial 
statements in the UK, including the FRC’s Ethical Standard  
as applied to listed entities, and we have fulfilled our other 
ethical responsibilities in accordance with these requirements. 
We believe that the audit evidence we have obtained is 
sufficient and appropriate to provide a basis for our opinion. 

Conclusions relating to going concern
We have nothing to report in respect of the following matters in 
relation to which the ISAs (UK) require us to report to you where: 

•  the Directors’ use of the going concern basis of accounting in the 
preparation of the financial statements is not appropriate; or

•  the Directors have not disclosed in the financial statements 

any identified material uncertainties that may cast significant 
doubt about the Group’s or the Parent Company’s ability 
to continue to adopt the going concern basis of accounting 
for a period of at least twelve months from the date when 
the financial statements are authorised for issue.

Key audit matters
Key audit matters are those matters that, in our professional 
judgment, were of most significance in our audit of the financial 
statements of the current period and include the most significant 
assessed risks of material misstatement (whether or not due to 
fraud) we identified, including those which had the greatest effect 
on: the overall audit strategy, the allocation of resources in the 
audit; and directing the efforts of the engagement team. These 
matters were addressed in the context of our audit of the financial 
statements as a whole, and in forming our opinion thereon, 
and we do not provide a separate opinion on these matters. 

Key audit matters impacting the 
Group financial statements
In respect of our audit of the Group financial 
statements we have determined that there are no 
key audit matters to communicate in our report.

Key audit matters impacting the Parent Company  
financial statements only
Investment in subsidiary: impairment review

As at 31 December 2019, the Parent Company held an investment 
of £26.9m in its subsidiary, Synairgen Research Limited (as set  
out in note 4 of the Parent Company financial statements).  
At each reporting date, management carries out an impairment 
review in accordance with accounting standards that involves 
assessing the recoverable amount of the investment by 
estimating future cash flows and discounting to present value. 
There is inherent uncertainty in estimating the timing and  
extent of future cash flows of a drug development company.

The degree of estimation and complexity involved in the 
impairment review, for example in determining the appropriate 
discount rate and clinical success probabilities to be applied to the 
cash flows, causes us to consider this to be a significant audit risk.

Independent Auditor’s Report 
to the members of Synairgen plc
(continued)

How We Addressed the Key Audit Matter in the Audit
We challenged the impairment review prepared by 
management through assessing the appropriateness 
of the key assumptions including:

•  The discount rate – through use of specialists and  
carrying out sensitivity analysis, using our internal 
valuations experts in order to assist with assessing 
the appropriateness of the discount rate;

•  The scale of the market opportunities used to develop 

future revenue forecasts – with reference to third 
party sources such as medical journals and publicly 
available information in respect of the structure and 
quantum of transactions involving similar assets;

•  Future development costs forecasts, by reference to 
supplier quotations and previous clinical trials and 
related development costs experience; and

•  The risk-weighting of estimated future cash flows - 
ensuring, through third party sources, that these 
weightings are in line with industry valuation practice.

We have assessed the methodology used in the 
preparation of the model with reference to the 
requirements of accounting standards.

We have also performed sensitivity analysis to test whether 
a reasonably possible change could result in an impairment. 
We also considered the adequacy of the disclosures in the 
financial statements relating to the directors’ assessment.

Based on the procedures we performed, we consider 
the estimates and judgements made by management to 
assess the carrying value of the investment in subsidiary 
to be reasonable. We reviewed the disclosures in note 
2 and are satisfied that they are appropriate.

Our application of materiality
Group materiality: £200,000 (2018: £170,000).
Parent Company materiality: £180,000 (2018: £140,000).

Our Group materiality was based upon 4% of the loss before 
tax for the year (2018: 5% of the loss before tax for the year). 
We consider losses before tax to be one of the principal 
considerations for the users of the financial statements 
in assessing the financial performance of the Group.

The audit of Synairgen Research Limited, the only subsidiary in 
the Group was performed to a materiality of £150,000, calculated 
on the same basis as that of the Group, while materiality 
for Synairgen plc, as the holding company, was capped at a 
level which is 90% (2018: 70%) of the Group materiality.

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 decisions of reasonable users that are 
taken on the basis of the financial statements. In order to 
reduce to an appropriately low level the probability that any 
misstatements exceed materiality, we use a lower materiality 
level, performance materiality, to determine the extent of 
testing needed. Importantly, misstatements below these 
levels will not necessarily be evaluated as immaterial as we 
also take account of the nature of identified misstatements, 
and the particular circumstances of their occurrence, when 
evaluating their effect on the financial statements as a whole.

Performance materiality was set at 75 per cent of the above 
materiality levels, being £150,000 (2018: £150,000) for the Group 
and £135,000 (2018: £105,000) for Synairgen plc. In setting the 
level of performance materiality we considered a number of 
factors including the expected total value of known and likely 
misstatements based on past experience and other factors.

We agreed with the audit committee that we would report to 
the committee all individual audit differences identified during 
the course of our audit in excess of £4,000 (2018: £4,000). We 
also agreed to report differences below these thresholds that, 
in our view, warranted reporting on qualitative grounds.

An overview of the scope of our audit
The Group’s operations are based solely in Southampton,  
United Kingdom. 

The scope of our Group audit was established by obtaining an 
understanding of the Group, including its control environment,  
and assessing the risks of material misstatement.

Both components, Synairgen plc and Synairgen Research 
Limited, are considered significant components and 
were subject to full-scope audits by BDO LLP.

Other information
The Directors are responsible for the other information.  
The other information comprises the information included in 
the 2019 annual report other than the financial statements 
and our auditor’s report thereon. Our opinion on the financial 
statements does not cover the other information and, except 
to the extent otherwise explicitly stated in our report, we do 
not express any form of assurance conclusion thereon.

In connection with our audit of the financial statements, our 
responsibility is to read the other information and, in doing so, 
consider whether the other information is materially inconsistent 
with the financial statements or our knowledge obtained in 
the audit or otherwise appears to be materially misstated. If 
we identify such material inconsistencies or apparent material 
misstatements, we are required to determine whether there 
is a material misstatement in the financial statements or a 
material misstatement of the other information. If, based on the 
work we have performed, we conclude that there is a material 
misstatement of this other information, we are required to report 
that fact. We have nothing to report in this regard.

Opinion on other matters prescribed by the  
Companies Act 2006
In our opinion, based on the work undertaken in the course of  
the audit:

•   the information given in the strategic report and the directors’ 
report for the financial year for which the financial statements 
are prepared is consistent with the financial statements; and

•   the strategic report and the directors’ report have been  

prepared in accordance with applicable legal requirements. 

Matters on which we are required to report by exception
In the light of the knowledge and understanding of the Group 
and the Parent Company and its environment obtained 
in the course of the audit, we have not identified material 
misstatements in the strategic report or the Directors’ report.

We have nothing to report in respect of the following 
matters in relation to which the Companies Act 2006 
requires us to report to you if, in our opinion:

•  adequate accounting records have not been kept by the 
Parent Company, or returns adequate for our audit have 
not been received from branches not visited by us; or

•  the Parent Company financial statements are not in 

agreement with the accounting records and returns; or

•  certain disclosures of Directors’ remuneration 

specified by law are not made; or  

•  we have not received all the information and 

explanations we require for our audit.

Responsibilities of directors
As explained more fully in the Statement of Directors’ 
responsibilities, the Directors are responsible for the 
preparation of the financial statements and for being satisfied 
that they give a true and fair view, and for such internal 

control as the Directors determine is necessary to enable 
the preparation of financial statements that are free from 
material misstatement, whether due to fraud or error.

In preparing the financial statements, the Directors are 
responsible for assessing the Group’s and the Parent 
Company’s ability to continue as a going concern, disclosing, 
as applicable, matters related to going concern and using the 
going concern basis of accounting unless the Directors either 
intend to liquidate the Group or the Parent Company or to 
cease operations, or have no realistic alternative but to do so.

Auditor’s responsibilities for the audit of  
the financial statements
Our objectives are to obtain reasonable assurance about 
whether the financial statements as a whole are free from 
material misstatement, whether due to fraud or error, and to 
issue an auditor’s report that includes our opinion. Reasonable 
assurance is a high level of assurance, but is not a guarantee 
that an audit conducted in accordance with ISAs (UK) will 
always detect a material misstatement when it exists.

Misstatements can arise from fraud or error and are considered 
material if, individually or in the aggregate, they could 
reasonably be expected to influence the economic decisions 
of users taken on the basis of these financial statements.

A further description of our responsibilities for the audit of 
the financial statements is located on the Financial Reporting 
Council’s website : www.frc.org.uk/auditorsresponsibilities. 
This description forms part of our auditor’s report.

Use of our report
This report is made solely to the Parent Company’s members, as 
a body, in accordance with Chapter 3 of Part 16 of the Companies 
Act 2006. Our audit work has been undertaken so that we might 
state to the Parent Company’s members those matters we 
are required to state to them in an auditor’s report and for no 
other purpose. To the fullest extent permitted by law, we do not 
accept or assume responsibility to anyone other than the Parent 
Company and the Parent Company’s members as a body, for our 
audit work, for this report, or for the opinions we have formed.

1. Accounting policies

Basis of preparation
The Group financial statements have been prepared in accordance with International Financial Reporting Standards, International Accounting 
Standards and Interpretations (collectively ‘IFRSs’) as adopted by the European Union (‘Adopted IFRSs’) and with those parts of the Companies 
Act 2006 applicable to companies preparing their financial statements under IFRSs.

The accounting policies adopted are consistent with those of the previous financial year except for the adoption of IFRS 16.

Adoption of new standards 

IFRS 16 Leases 
The Group has adopted IFRS 16 Leases with effect from 1 January 2019 and the accounting policy is detailed in note 11. This has resulted in the 
Group’s lease with the University of Southampton being brought onto the statement of financial position, as both a right-of-use asset and a lease 
liability. The right-of-use asset and lease liability are both based on the present value of lease payments due over the term of the lease, with the 
asset being depreciated and the liability increased for the accretion of interest and reduced by lease payments.

Other new standards 
Other new amended standards and interpretations issued by the International Accounting Standards Board (IASB) that apply to the financial 
statements do not impact the Group as they are either not relevant to the Group’s activities or require accounting which is consistent with the 
Group’s current accounting policies.

There are a number of standards and amendments to standards, and interpretations which have been issued by the IASB that are effective in 
future accounting periods that the Group has decided not to adopt early. The most significant of these (which are all effective for the period 
beginning 1 January 2020) are (i) Amendments to References to the Conceptual Framework in IFRS Standards; and (ii) Amendments to IAS 1 and 
IAS 8 – Definition of Material. The Group is currently assessing the impact of these new standards and amendments. The Group does not expect 
any other standards issued by the IASB, but not yet effective, to have a material impact on the Group. 

The Group financial statements are presented in Sterling.

Going concern 
The directors have prepared financial forecasts to estimate the likely cash requirements of the Group over the next twelve months, given its stage of 
development and lack of recurring revenues. In preparing these financial forecasts, the directors have made certain assumptions with regards to the 
timing and amount of future expenditure over which they have control. The directors have attempted to take a prudent view in preparing these forecasts, 
recognising the inherent variability in costs of the ongoing  clinical trials of SNG001 in COVID-19 patients. 

After due consideration of these forecasts and current cash resources, the directors consider that the Company and the Group have adequate financial 
resources to continue in operational existence for the foreseeable future (being a period of at least twelve months from the date of this report) and, for 
this reason, the financial statements have been prepared on a going concern basis.

Basis of consolidation 
The consolidated financial statements incorporate the financial statements of the Company and entities controlled by the Company (as detailed in 
note 4 to the Parent Company Financial Statements on page 49) made up to the reporting date. All intra-group transactions, balances, income and 
expenses are eliminated on consolidation. The formation of the Group arose from merger accounting and as the business combination took place 
prior to 1 July 2006, the date of transition to IFRS, the transaction has not been restated as permitted by IFRS 1 “First-time Adoption of International 
Financial Reporting”.

Revenue 
Revenue is stated net of value added tax. 

The Group’s licensing and collaboration agreement with Pharmaxis in respect of the jointly developed LOXL2 inhibitors was renegotiated in 
December 2017. As no substantive performance obligations remained at 1 January 2019, it was treated as a completed contract on transition to 
IFRS 15 and the Group elected to account for the income related to it in the 2017 financial year, together with any future income resulting from the 
Group’s share of its partner’s future income from the collaboration, under IAS 18. Only the up-front receipt was recognised as revenue in 2017, as 
a reliable estimate of the other amounts which might be received could not be made at that time. Revenue from other amounts which may be 
received in future under this agreement, will be recognised when a reliable estimate can be made, which is likely to be when the partner’s income 
has been earned and the Group’s share is contractually due.

Revenue from the provision of services (which is not considered to be material in the current or prior year) is recognised over time, based on the 
estimated stage of completion of the contracted work.

for the year ended 31 December 2019 (continued)

1. Accounting policies (continued) 

Research and development
All ongoing research expenditure is currently expensed in the period in which it is incurred. Due to the regulatory and other uncertainties inherent 
in the development of the Group’s products, the criteria for development costs to be recognised as an asset, as set out in IAS 38 “Intangible Assets”, 
are not met until a product has been submitted for regulatory approval and it is probable that future economic benefit will flow to the Group.  
The Group currently has no such qualifying expenditure.

Employee benefits
All employee benefit costs, notably salaries, holiday pay, bonuses and contributions to personal defined contribution pension schemes are charged 
to the consolidated statement of comprehensive income on an accruals basis.

Share-based payments
Where equity-settled share options are awarded to employees, the fair value of the options at the date of grant is charged to the consolidated 
statement of comprehensive income over the vesting period. Non-market vesting conditions are taken into account by adjusting the number of 
equity instruments expected to vest at each reporting date so that, ultimately, the cumulative amount recognised over the vesting period is based 
on the number of options that eventually vest. Non-vesting conditions and market vesting conditions are factored into the fair value of the options 
granted. As long as all other vesting conditions are satisfied, a charge is made irrespective of whether the market vesting conditions are satisfied. 
The cumulative expense is not adjusted for failure to achieve a market vesting condition. 

Intangible assets
Intangible assets are stated at cost less any accumulated amortisation and any accumulated impairment losses. Patent costs are amortised over 
ten years on a straight-line basis and the amortisation cost is charged to research and development expenditure in the consolidated statement of 
comprehensive income. 

Property, plant and equipment
Property, plant and equipment are stated at cost less any accumulated depreciation and any accumulated impairment losses. Depreciation is 
provided on a straight-line basis at rates calculated to write off the cost of property, plant and equipment less their estimated residual value over 
their expected useful lives, which are as follows:

Computer equipment: 
Laboratory and clinical equipment: 

3 years 
5 years

The carrying values of property, plant and equipment are reviewed for impairment if events or changes in circumstances indicate that the carrying 
value may not be recoverable.

Inventories
Inventories are stated at the lower of cost and net realisable value.

Financial instruments
Financial assets and financial liabilities are recognised on the Group’s consolidated statement of financial position when the Group becomes a party 
to the contractual provisions of the instrument.

Financial assets
The Group classifies its financial assets as financial assets held at amortised cost.

These assets arise principally from the provision of goods and services to customers (eg trade receivables), but also incorporate other types of 
financial assets where the objective is to hold these assets in order to collect contractual cash flows and the contractual cash flows are solely 
payments of principal and interest. They are initially recognised at fair value plus transaction costs that are directly attributable to their acquisition 
or issue, and are subsequently carried at amortised cost using the effective interest rate method, less provision for impairment. 

The Group’s financial assets measured at amortised cost comprise trade and other receivables, other financial assets and cash and cash 
equivalents in the consolidated statement of financial position. Other financial assets comprise short-term deposits not meeting the IAS 7 definition 
of a cash equivalent. Cash and cash equivalents includes cash in hand, deposits held at call with banks, other short term highly liquid investments 
with original maturities of three months or less.

Financial liabilities
The Group classifies its financial liabilities as financial liabilities held at amortised cost. Trade payables are initially recognised at fair value and 
subsequently carried at amortised cost using the effective interest rate method.

Leases
All leases are accounted for by recognising a right-of-use asset and a lease liability except for leases of low value assets and leases with a duration of 
twelve months or less.

IFRS 16 was adopted 1 January 2019 without restatement of comparative figures. For an explanation of the transitional requirements that were 
applied as at 1 January 2019, see note 11. The following policies apply subsequent to the date of initial application, 1 January 2019.

Lease liabilities are measured at the present value of the contractual payments due to the lessor over the lease term, with the discount rate 
determined by reference to the rate inherent in the lease unless (as is typically the case) this is not readily determinable, in which case the Group’s 
incremental borrowing rate on commencement of the lease is used. Variable lease payments are only included in the measurement of the lease 
liability if they depend on an index or rate. In such cases, the initial measurement of the lease liability assumes the variable element will remain 
unchanged throughout the lease term. Other variable lease payments are expensed in the period to which they relate.

On initial recognition, the carrying value of the lease liability also includes: amounts expected to be payable under any residual value guarantee;  
the exercise price of any purchase option granted in favour of the Group if it is reasonably certain to exercise that option; and any penalties payable 
for terminating the lease, if the term of the lease has been estimated on the basis of termination option being exercised.

Right-of-use assets are initially measured at the amount of the lease liability, reduced for any lease incentives received, and increased for: lease 
payments made at or before commencement of the lease; initial direct costs incurred; and the amount of any provision recognised where the 
Group is contractually required to dismantle, remove or restore the leased asset.

Subsequent to initial measurement, lease liabilities increase as a result of interest charged at a constant rate on the balance outstanding and are 
reduced for lease payments made. Right-of-use assets are amortised on a straight-line basis over the remaining term of the lease or over the 
remaining economic life of the asset if, rarely, this is judged to be shorter than the lease term.

When the Group revises its estimate of the term of any lease (because, for example, it re-assesses the probability of a lessee extension or 
termination option being exercised), it adjusts the carrying amount of the lease liability to reflect the payments to make over the revised term,  
which are discounted at the same discount rate that applied on lease commencement. The carrying value of lease liabilities is similarly revised  
when the variable element of future lease payments dependent on a rate or index is revised. In both cases an equivalent adjustment is made to  
the carrying value of the right-of-use asset, with the revised carrying amount being amortised over the remaining (revised) lease term.

When the Group renegotiates the contractual terms of a lease with the lessor, the accounting depends on the nature of the modification:

• 

• 

• 

if the renegotiation results in one or more additional assets being leased for an amount commensurate with the standalone price for 
the additional rights-of-use obtained, the modification is accounted for as a separate lease in accordance with the above policy;

in all other cases where the renegotiation increases the scope of the lease (whether that is an extension to the lease term, or one or 
more additional assets being leased), the lease liability is remeasured using the discount rate applicable on the modification date,  
with the right-of-use asset being adjusted by the same amount; and

if the renegotiation results in a decrease in the scope of the lease, both the carrying amount of the lease liability and right-of-use asset 
are reduced by the same proportion to reflect the partial or full termination of the lease with any difference recognised in profit or 
loss. The lease liability is then further adjusted to ensure its carrying amount reflects the amount of the renegotiated payments over 
the renegotiated term, with the modified lease payments discounted at the rate applicable on the modification date. The right-of-use 
asset is adjusted by the same amount.

For contracts that both convey a right to the Group to use an identified asset and require services to be provided to the Group by the lessor,  
the Group has elected to account for the entire contract as a lease, i.e. it does not allocate any amount of the contractual payments to,  
and account separately for, any services provided by the supplier as part of the contract.

1. Accounting policies (continued) 

Taxation
Income tax is recognised or provided at amounts expected to be recovered or to be paid using the tax rates and tax laws that have been enacted or 
substantively enacted at the reporting date. Research and development tax credits are included as an income tax credit under current assets.

5. Employee benefit expense

The average monthly number of employees (including executive directors) was:

Deferred tax balances are recognised in respect of all temporary differences that have originated but not reversed by the reporting date except for 
differences arising on:

Research

Administration

• 

• 

investments in subsidiaries where the Group is able to control the timing of the reversal of the difference and it is probable that the 
difference could not reverse in the foreseeable future; and

the initial recognition of an asset or liability in a transaction which is not a business combination and at the time of the transaction affects 
neither accounting or taxable profit.

The amount of the asset or liability is determined using tax rates that have been enacted or substantively enacted by the reporting date and are 
expected to apply when the deferred tax liabilities/(assets) are settled/(recovered).

Recognition of deferred tax assets is restricted to those instances where it is probable that a taxable profit will be available against which the  
temporary difference can be utilised. Deferred tax balances are not discounted.

2. Critical accounting estimates and judgements

Critical accounting estimates, assumptions and judgements are continually evaluated by management based on available information and experience. 
As the use of estimates is inherent in financial reporting, actual results could differ from these estimates.

There are no critical accounting estimates and judgements.

3. Segmental analysis

The Group operates in one area of activity, namely drug discovery and development.  All assets of the Group are located within the United Kingdom  
and all losses were generated in that territory. The revenue generated in 2018 was generated from one customer.

4. Loss from operations

The loss from operations has been arrived at after charging:

Depreciation of property, plant and equipment

Depreciation of right-of-use assets

Amortisation of intangible assets

Operating lease rentals payable:

 Land and buildings

 Other operating lease rentals

Finance Act 2015 included provision for the main rate of corporation tax to reduce from 20% to 19% on 1 April 2017. Finance Act 2016 included 
provision for the rate to reduce further to 17% on 1 April 2020.  This will reduce the Company’s future tax charge accordingly. The 17% tax rate was 
substantively enacted on 15 September 2016. Accordingly, deferred tax balances have been recognised at 17%, being as at 31 December 2019 the 
rate of corporation tax expected to be in force at the time that these timing differences are expected to reverse. Post year-end, a change to the main 
UK corporation tax rate, announced in the Budget on 11 March 2020, was substantively enacted on 17 March 2020. The rate applicable from 1 April 
2020 now remains at 19%, rather than the previously enacted reduction to 17%. However as this is classified as a non-adjusting post balance sheet 
event the deferred tax balances remain recognised at 17%. The impact of this change to the unrecognised deferred tax asset is shown below.

At 31 December 2019 the Group has trading losses carried forward which are available for offset against future profits of the Group amounting to 
£16,653,000 (2018: £14,964,000) and non-trading losses of £2,444,000 (2018: £2,222,000). At 31 December 2019 the Group has an unrecognised 
deferred tax asset in respect of these losses of £3,247,000 (2018: £2,922,000). The full utilisation of these losses in the foreseeable future is  
uncertain and no deferred tax asset has therefore been recognised.

In addition to the deferred tax asset on losses, the Group has a potential future tax deduction on share options of £248,000 (2018: £429,000)  
and a deferred tax asset of £42,000 (2018: £73,000) thereon. The additional tax deduction will crystallise at the point the options are exercised.  
As the utilisation of this additional deduction against taxable profits in the Group is uncertain, no deferred tax asset has been recognised in  
respect of the future tax deduction on share options.

As noted above the unrecognised deferred tax asset at 31 December 2019 is calculated at a rate of 17%. If this amount had been calculated at 19% 
the unrecognised deferred tax asset would increase to £3,676,000.

Basic loss per share is calculated by dividing the loss attributable to ordinary equity holders of the parent company by the weighted average  
number of ordinary shares in issue during the year.

The loss attributable to ordinary shareholders and weighted average number of ordinary shares for the purpose of calculating the diluted earnings 
per ordinary share are identical to those used for basic loss per share. This is because the exercise of share options would have the effect of  
reducing the loss per ordinary share and is therefore antidilutive under the terms of IAS 33.

120

All leases are accounted for by recognising a right-of-use asset and a lease liability except for:

•  Leases of low value assets; and 

•  Leases with a duration of 12 months or less.

The Group has one lease with its landlord, the University of Southampton, which provides the Group with office space and access  
to laboratory equipment. At 1 January 2019 the existing lease (the ‘Existing Lease’) had 7 months to run and therefore was covered 
by one of the exclusions noted above. A new two year lease (the ‘New Lease’) was entered into with effect from 1 August 2019. 

IFRS 16 was adopted on 1 January 2019 using the modified retrospective method without restatement of comparative figures.  
The New Lease has been accounted for by recognising a right-of-use asset and a lease liability.

The lease liability has been measured at the present value of the contractual payments due to the lessor over the lease term  
using a discount rate of 5%, which is an estimate of the discount rate applicable to a property lease. 

The right-of-use asset has been initially measured at the amount of the lease liability. Subsequent to initial measurement the  
lease liability increases as a result of interest charged at a constant rate on the balance outstanding and is reduced for any  
lease payments made. Right-of-use assets are depreciated on a straight-line basis over the remaining term of the lease.

The objective of holding financial instruments is to have access to finance for the Group’s operations and to manage related risks.  
The main risks arising from holding these instruments are interest rate risk, liquidity risk, credit risk and currency risk.

Interest rate risk
The Group’s deposit balances are subject to the risk of fluctuating base rates.

Short-term deposits are placed with banks for periods of up to twelve months and are categorised as floating rate financial assets. Contracts in 
place at 31 December 2018 had a weighted average period to maturity of 53 days and a weighted average annualised rate of interest of 0.85%.

Sensitivity analysis
It is estimated that an increase of quarter of one percentage point in interest rates would have decreased the Group’s loss before taxation by 
approximately £9,000 (2018: £14,000).  

Liquidity risk
The Group’s policy is to maintain adequate cash resources to meet liabilities as they fall due. All Group payable balances as at 31 December 2019 
and 31 December 2018 fall due for payment within one year. Cash balances are placed on deposit for varying periods with reputable banking 
institutions to ensure there is limited risk of capital loss. The Group does not maintain an overdraft facility.

Credit risk
The Group’s credit risk is attributable to its banking deposits. The Group follows a risk-averse policy of treasury management. Sterling deposits 
are held with one or more approved UK-based financial institutions (HSBC UK Bank plc, Bank of Scotland plc and National Westminster Bank 
Plc, which at 31 December 2019 had good short term credit ratings, being at least F1 for Fitch, P-1 for Moody’s and A-1 for Standard and Poor’s) 
and in the Institutional Cash Series plc Institutional Sterling Liquidity Fund managed by BlackRock Investment Management (UK) Limited (rated 
at 31 December 2019 as AAAmmf by Fitch, Aaa-mf by Moody’s and AAAm by Standard and Poor’s). The Group’s primary treasury objective is 
to minimise exposure to potential capital losses whilst at the same time securing prevailing market rates. The Group seeks to lessen risk by 
placing its cash deposits with at least three of the above institutions.

Currency risk
During the year under review, the Group was exposed to Euro currency movement as some of the pharmaceutical development costs  
for the interferon beta trial were denominated in Euros. To hedge against currency movement, the Group purchased Euros before the  
payment was due.

The Group considers its capital to be its total equity, which at 31 December 2019 amounted to £2.25 million (2018: £6.03 million). The Group’s 
objectives when managing capital are to safeguard the Group’s ability to continue as a going concern in order to provide returns to equity holders of 
the Company and benefits to other stakeholders and to maintain an optimal capital structure to reduce the cost of capital. The Group manages this 
objective through tight control of its cash resources and, upon reaching significant drug development programme milestones (to decrease investment 
risk), by raising additional equity from shareholders to meet its forecast future cash requirements.

Net funds held by the Group at 31 December 2019 amounted to £2.45 million and comprised short-term deposits (with original maturities of greater 
than three months and less than one year) and cash and cash equivalents as shown below:

The Company has applied IFRS 2 to all the above share-based payments and the following comments apply to these options:

(i)  Stochastic valuation methodology was used for all awards.
(ii)  Expected dividend yield is nil, consistent with the directors’ view that the Group’s model is to generate value through capital growth rather than payment of dividends.
(iii)  The risk free rate is equal to the prevailing UK Gilts rate at grant date that most closely matches the expected term of the grant.
(iv)  The fair value charge is spread evenly over the expected vesting period.
(v)  Volatility for the grants made in 2018 and 2019 was calculated by reviewing share price movement over the period of three years prior to grant, excluding any large 

share price movements (as these were not considered to be representative of future expectations of volatility). 
(vi)   The charge for the year ended 31 December 2019 for share-based payment amounted to £111,000 (2018: £98,000).

Parent Company Balance Sheet 

for the year ended 31 December 2019 (continued)

as at 31 December 2019

19. Capital and reserves 

19a Share capital 
Share capital represents the nominal value of shares issued.

19b Share premium
Share premium represents amounts subscribed for share capital in excess of nominal value less the related costs of share issues.

19c Merger reserve
The merger reserve represents the reserve arising on the acquisition of Synairgen Research Limited on 11 October 2004 via a share for share 
exchange accounted for as a Group reconstruction using merger accounting under UK GAAP.

19d Retained deficit
The retained deficit represents cumulative net gains and losses recognised in the consolidated statement of comprehensive income, adjusted for 
cumulative recognised share-based payments.

20. Related party transactions and balances

Details of key management personnel and their compensation are given in note 5 and on pages 20 and 21 of the Directors’ Remuneration Report.

21. Post balance sheet event

Post year-end, COVID-19 developed into a global pandemic. As described in the Strategic Report, the Group is now evaluating SNG001 in clinical trials 
of COVID-19 patients. The Group also paused its SG015 trial in March 2020, having dosed 109 of the targeted 120 patients, and will now conduct an 
unplanned interim analysis of the results. The potential therapeutic benefits of interferon beta for patients with COVID-19 is now being explored in 
two clinical trials. The impact of lockdown and the challenge of commencing two new trials in a very short timescale has placed a significant burden 
on staff, whose response has been outstanding. With the exception of clinical staff who are working on the COVID-19 clinical trials and a small number 
of laboratory staff, all other staff have worked from home and communications have been facilitated by conference calls and videoconferencing. Key 
suppliers have also continued working during lockdown and this has not materially impeded on our ability to commence the trials in COVID-19 patients. 

On 26 March 2020, the Company announced that it had conditionally raised £14.0 million (before expenses) by a fundraising of 40,000,000 ordinary 
shares at a price of 35 pence per share. The fundraising comprised a placing of 10,943,295 ordinary shares admitted on 30 March 2020 (made pursuant 
to existing authorities to allot shares for cash and disapply pre-emption rights) and a placing and subscription of 29,056,705 ordinary shares admitted 
on 15 April 2020 (approved by shareholders in a general meeting on 14 April 2020). Total expenses of the fundraising were approximately £0.8 million.

The fundraising was for the following purposes:

•  COVID-19 clinical trial activity (£7 million);

•  Manufacture of SNG001 drug product and other supply chain considerations (£4 million); and

• 

Strengthened balance sheet for potential partnering discussions, working capital and fees (£3 million).

At this time it is unclear what the medium and long term impact of COVID-19 will be on the wider economy and how this will affect the Group.  
The COVID-19 pandemic wasn’t a condition in existence at the year-end date and therefore it is being treated as a non-adjusting subsequent event.

Notes to the Parent Company Financial Statements 

Notes to the Parent Company Financial Statements 

for the year ended 31 December 2019 (continued)

for the year ended 31 December 2019 (continued)

1. Accounting policies

Basis of preparation

The financial statements have been prepared in accordance with Financial Reporting Standard 101 Reduced Disclosure Framework (‘FRS 101’).

Disclosure exemptions adopted

In preparing these financial statements the Company has taken advantage of all disclosure exemptions conferred by FRS 101.  
Therefore these financial statements do not include:

•  certain comparative information as otherwise required by EU-endorsed IFRS;

•  certain disclosures regarding the Company’s capital;

•  a statement of cash flows;

•  the effect of future accounting standards not yet adopted;

•  the disclosure of the remuneration of key management personnel; and

•  disclosures of related party transactions with other wholly-owned members of Synairgen plc group of companies.

In addition, and in accordance with FRS 101, further disclosure exemptions have been adopted because equivalent disclosures are included in the 
Company’s consolidated financial statements. These financial statements do not include certain disclosures in respect of:

•  share-based payments; or

•  financial instruments. 

Going Concern
The directors have prepared financial forecasts for the next twelve months to estimate the likely cash requirements of the Company and its 
subsidiary Synairgen Research Ltd, to which the Company has confirmed its intention to provide financial support for a period of not less than 
one year from the date that its financial statements for the year ended 31 December 2019 are signed, given its stage of development and lack of 
recurring revenues. In preparing these financial forecasts, the directors have made certain assumptions with regards to the timing and amount of 
future expenditure over which they have control. The directors have attempted to take a prudent view in preparing these forecasts, recognising 
the inherent variability in costs of the ongoing clinical trials of SNG001 in COVID-19 patients being conducted by Synairgen Research Ltd. 

After due consideration of these forecasts and current cash resources, the directors consider that the Company has adequate 
financial resources to continue in operational existence for the foreseeable future (being a period of at least twelve months from 
the date of this report), and for this reason, the financial statements have been prepared on a going concern basis.

Principal accounting policies
The principal accounting policies adopted in the preparation of the financial statements are set out below.  
The policies have been consistently applied to all the years presented.

Investments in subsidiary undertakings
Investments in subsidiary undertakings where the Company has control are stated at cost less any provision for impairment. 

Financial instruments
Financial assets and financial liabilities are recognised on the Company’s balance sheet when the Company becomes a party to  
the contractual provisions of the instrument.

Financial assets

The Company classifies its financial assets as financial assets held at amortised cost.

These assets incorporate types of financial assets where the objective is to hold these assets in order to collect contractual 
cash flows and the contractual cash flows are solely payments of principal and interest. They are initially recognised 
at fair value plus transaction costs that are directly attributable to their acquisition or issue, and are subsequently 
carried at amortised cost using the effective interest rate method, less provision for impairment. 

The Company’s financial assets measured at amortised cost comprise debtors, investments: short-term deposits and 
cash and cash equivalents in the balance sheet. Investments: short-term deposits comprise short-term deposits not 
meeting the definition of a cash equivalent. Cash and cash equivalents includes cash in hand, deposits held at call with 
banks and other short term highly liquid investments with original maturities of three months or less.

Financial liabilities

Share-based payments
When the Company grants options over equity instruments directly to the employees of a subsidiary undertaking, the effect of the share-based 
payment is capitalised as part of the investment in the subsidiary as a capital contribution, with a corresponding increase in equity.

Taxation
The charge for taxation is based on the loss for the period and takes into account taxation deferred.

Current tax is measured at amounts expected to be paid using the tax rates and laws that have been enacted or substantively enacted by the 
balance sheet date. Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the balance 
sheet date, except that the recognition of deferred tax assets is limited to the extent that the Company anticipates making sufficient taxable profits 
in the future to absorb the reversal of the underlying timing differences. Deferred tax balances are not discounted.

Share capital
The Group’s ordinary shares are classified as equity instruments. Financial instruments issued by the Company are classified as equity  
only to the extent that they do not meet the definition of a financial liability or financial asset.

2. Critical accounting estimates and judgements 

Critical accounting estimates, assumptions and judgements are continually evaluated by management based on available information and experience.  
As the use of estimates is inherent in financial reporting, actual results could differ from these estimates.

The Company holds a significant investment in its subsidiary, Synairgen Research Limited, of £26.9 million (2018: £24.3 million). In assessing the carrying 
value of this asset for impairment, the directors have exercised judgement in estimating its recoverable amount, including the value of the inferferon beta 
programmes and the share of the LOXL2 collaboration with Pharmaxis. The value of the interferon beta programmes for 2019 is based on the COPD and 
immuno-compromised patient indications (2018 – COPD alone). The potential value of interferon beta in COVID-19 patients has been excluded from the 
impairment review at 31 December 2019, as the pandemic and related treatment opportunity is considered a non-adjusting post balance sheet event.  
The determination of the valuation for these assets is based on the discounted value of the estimated probability-adjusted future cash flows generated 
from out-licensing transactions. The valuation is derived from a financial model that evaluates a range of potential outcomes from what are considered  
the key variables, including the probability of the success of clinical trials, the expected licensing terms that will be negotiated and the anticipated peak  
sales values for the resultant drugs. 

The most significant judgement in arriving at the valuation is the quantity and timing of forecast cash flows from future out-licensing. Given the level of 
headroom indicated by the impairment review, based on the discount rate assumption of 12%, which is applied to a series of probability-adjusted cash 
flows, the recoverable amount of the investment is not considered to be sufficiently sensitive to a reasonably possible increase in the discount rate, to 
impact the conclusion of the review. At this stage of the product development, the key sensitivity is the probability of successful completion of clinical trials  
in the interferon beta programmes. A failure in the development of either of these assets might result in an impairment of the investment in the subsidiary.

3. Profit and loss account

which are ascribed as forming part of these financial statements.

The Company classifies its financial liabilities as financial liabilities held at amortised cost. Trade creditors are initially recognised at fair value and 
subsequently carried at amortised cost using the effective interest rate method.

Auditor’s remuneration is disclosed in note 4 to the Group accounts on page 35.
