Chairman’s Statement

Synairgen has made significant progress during 2020, from being 
one of the first movers in the UK to begin clinical trials to combat 
COVID-19, to ending the year with compelling clinical data and late-
stage clinical trials underway both in the UK and internationally 
to investigate our inhaled interferon beta candidate (SNG001) 
in patients with COVID-19. The year has been unprecedented 
globally for all sectors, and the healthcare industry, and in 
particular biotechnology, has played a central role. Synairgen’s 
expanded team and speed to action has enabled the Company to 
make significant strides in the fight against COVID-19. Synairgen 
has a potential role to play in the provision of a life-saving 
treatment against COVID-19 and other viruses, and in situations 
where the various vaccines may not prove effective or suitable. 

In July 2020, we received landmark positive results in the Phase II 
study SG016 in hospitalised COVID-19 patients. This paved the 
way for our follow-on trial in the home setting and, ultimately,  
our larger multinational Phase III study SG018, which has been 
approved to commence by regulators in 12 countries. The 
importance of progress being made in trials of COVID-19 
treatments cannot be understated. While vaccination efforts are 
crucial to defeating the pandemic, we also need therapeutics to 
save lives and to help those who become infected despite 
vaccination. Based on the compelling data published in November 
2020 in the Lancet Respiratory Medicine journal supported by 
evidence from the recently announced home-based trial results, 
we believe Synairgen’s inhaled interferon beta candidate could 
play a critical role in addressing the impact of COVID-19 and 
similar viruses by reducing the severity of the disease and 
accelerating patient recovery.

The inclusion of SNG001 in the US government-funded 
ACTIV-2 trial is a further indication of international interest 
in our inhaled interferon beta treatment. Unlike many 
other treatments, inhaled interferon beta, as a drug taken 
through a nebuliser, can be self-administered at home under 
virtual supervision, making it a key part of reducing strain 
on healthcare systems, both through preventing severe 
disease and through lowering the number of necessary 
hospital visits for patients suffering respiratory symptoms. 

These successes reflect the scientific research supporting the role 
of interferons in orchestrating antiviral responses undertaken by 
our scientific founders, Prof. Donna Davies, Prof. Ratko Djukanovic, 
and Prof. Sir Stephen Holgate, who continue to play an active role 
in Synairgen. 2021 is set to be an even more impactful year for 
Synairgen pending the clinical results from our late-stage trials 
evaluating SNG001. We are optimistic about the potential for 
inhaled interferon beta as a potentially effective treatment for 
COVID-19 and future viral outbreaks.   

It has been a very challenging year for Synairgen’s staff, combining 
the significant additional workload of our COVID-19 programmes 
and an escalation of our manufacturing and commercialisation 
strategies with the logistical limitations of lockdown and travel 
restrictions. On behalf of the Board, I wholeheartedly thank 
our staff and outsourced contractors for their hard work, 
perseverance and resilience.  

Thanks to the support of our shareholders, Synairgen is in a 
robust financial position following two oversubscribed fundraises 
during the year. We continue to scale up operations and prepare 
for commercialisation of the product and look forward to 
reporting further progress in the coming months.

Strategic Report

The directors present their Strategic Report  
for the year ended 31 December 2020.

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

Synairgen is developing a broad-spectrum inhaled 
antiviral for the treatment of severe viral lung infections 
and is currently conducting a Phase III clinical trial for 
COVID-19. Launch preparations are underway, which 
may involve licensing or partnership. A glossary on pages 
58 to 61 provides additional explanation of some of the 
more detailed scientific and clinical terminology.

Operating Review

Summary
2020 was an unprecedented year for Synairgen. We were able 
to respond rapidly to the COVID-19 crisis and continue on our 
mission to bring our inhaled interferon beta-1a drug product to 
patients for the treatment of COVID-19.

SNG001 has potential value in three settings:  

1.  The near term business objective is to gain registrations  
as soon as possible to treat patients with COVID-19:

(i) 

 in the hospital setting, to prevent further deterioration 
 and death, and to accelerate discharge from hospital    
 and rate of recovery; 

(ii)  in non-hospitalised patients with significant  

breathlessness, to prevent hospitalisation and   
accelerate recovery; and

(iii) to reduce the number of patients who develop Long COVID

2.  The medium term business objective is to work with 
governments to prepare for the next pandemic. The 
SARS-CoV-2 pandemic has demonstrated the value of 
being prepared. Providing SNG001 trials continue to 
produce positive data, SNG001, as a broad-spectrum 
antiviral, could be stockpiled for future pandemics. It 
can be stored in concentrated form in freezers for over 
six years, and in ready to use format for three years.

3.  The long term business model envisages applying SNG001’s 

broad-spectrum antiviral activity to treat patients hospitalised 
on account of a severe viral lung infection. Chest infections are 
the fifth largest cause of death globally1 and approximately 
half of chest infections have a viral component.2

Progress in 2020
During the year Synairgen made significant clinical progress 
with its inhaled formulation of interferon beta, SNG001. Results 
from the SG016 Phase II trial of SNG001 in 101 hospitalised 
COVID-19 patients support its use as a valuable treatment option 
to prevent development of severe disease and to expedite 
patient recovery. Further safety, efficacy and other supporting 
data were provided from the interim analysis of Synairgen’s 
SG015 Phase II COPD trial in September 2020. Expansion of 
the SG016 trial to include an additional 120 patients treated 
in the home environment was completed post period-end in 
January 2021, with analysis of the combined data from the 
Hospital and Home Cohorts announced in April 2021 showing 
that the more breathless patients are significantly more likely to 
recover to “no limitation of activities” on SNG001 than placebo. 

Based on the positive outcome of these Phase II results, 
SNG001 is being trialled in COVID-19 patients around the 
world. Synairgen has initiated an international Phase III trial 
(SG018), which will involve a total of 610 hospitalised COVID-19 
patients who require supplemental oxygen. Our inhaled 
interferon beta has also been included in the US government-
funded ACTIV-2 Phase II/III trial in COVID-19 outpatients. 
Dosing began in both trials post period-end in Q1 2021. 

The Company is currently focused on progressing these trials to 
produce the data for accelerated regulatory approvals of SNG001 
as a COVID-19 treatment. We are also working on the supply chain 
in preparation for launch.

COVID-19
COVID-19, caused by the SARS-CoV-2 virus, is a global pandemic 
and there has been, and continues to be, an urgent need to 
assess new treatments to prevent and effectively treat the 
severe lower respiratory tract illness that can occur with 
this disease. Older people and those with co-morbidities 
such as obesity, heart and lung complications or diabetes 
are at greatest risk of developing severe or fatal disease. 

The SARS-CoV-2 knowledge base is continually expanding 
with respect to transmissibility and pathogenicity of 
the virus and its variants, and the effectiveness of the 
interventions, which include social distancing, vaccines 
and therapeutics. The need for a therapeutic persists to 
cover the possibility that vaccine effectiveness wanes, 
or that vaccine rollout and uptake is sub-optimal.

Rationale for the use of inhaled interferon beta  
to treat COVID-19
Interferon beta (‘IFN-beta’) is a naturally-occurring protein, 
orchestrating the body’s antiviral responses. There is growing 
evidence that deficiency in IFN-beta production by the lung could 
explain the enhanced susceptibility in ‘at-risk’ patient groups to 
developing severe lower respiratory tract (lung) disease during 
respiratory viral infections. Furthermore, viruses, including 
coronaviruses such as SARS-CoV-2, have evolved mechanisms 
to suppress endogenous IFN-beta production, helping the virus 
to evade the innate immune system. The addition of exogenous 
IFN-beta before or during viral infection of lung cells in vitro either 
prevents or greatly reduces viral replication. The Company is 
currently conducting further in vitro testing of SNG001 against 
two SARS-CoV-2 variants. Synairgen’s SNG001 is a formulation 
containing the fully glycosylated form of IFN-beta (IFN-beta-1a) 
for direct delivery to the lungs via specific nebulisers. It is near to 
pH neutral, and is free of mannitol, arginine and human serum 
albumin, which may be pharmacologically active in the airways, 
making it suitable for inhaled delivery direct to the site of infection, 
where the aim is to halt progression of disease, reduce duration of 
stay in hospital and prevent further deterioration and death. 

The inhaled route of delivery is necessary if levels of IFN-beta are 
to be attained in the lungs at the concentration needed to drive 
antiviral activity. We believe these concentrations could not be 
accomplished at the lining of the lungs via the injected route.

COVID-19 Phase II trial – SG016
Synairgen’s Phase II clinical trial in COVID-19 patients, SG016, was a 
double-blind, placebo-controlled trial. The two cohort 221 patient 
trial comprised 101 patients randomised in the hospital setting 
(initial results reported 20 July with further analyses announced 
in September 2020), and a further 120 patients randomised in 
the home setting (trial recruitment completed, with initial data 
announced in April 2021). 

SG016: Hospital Cohort
Synairgen’s Phase II trial of SNG001 in hospitalised COVID-19 
patients was conducted across nine NHS trusts in the UK and 
was adopted by the NIHR Respiratory Translational Research 
Collaboration, who gave it Urgent Public Health status. 

The design of this trial, which began dosing patients in March 2020, 
was based on the recommendations contained within the World 
Health Organization (WHO) R&D Blueprint Novel Coronavirus 
COVID-19 Therapeutic Trial Synopsis issued in February 2020. 

On 20 July 2020, the Company announced positive top-line results 
from the trial with further analyses announced in September 2020. 
The primary endpoint was the change in condition assessed using 
the WHO Ordinal Scale for Clinical Improvement (OSCI) during the 
dosing period.

In November, these results were published in the peer-reviewed 
Lancet Respiratory Medicine journal. The full title of the publication 
is: “Safety and efficacy of inhaled nebulised interferon beta-1a (SNG001) 
for treatment of SARS-CoV-2 infection: a randomised, double-blind, 
placebo-controlled, phase 2 trial”.

Key findings included:

•  The odds of improvement across the entire OSCI scale were 
more than two-fold greater in the SNG001 group than the 
placebo group at the end of the treatment period in both the  
ITT (Intention-To-Treat) population (OR 2.32; p=0.033) and the  
PP (Per Protocol) population (OR 2.80; p=0.017).

•  There was a trend towards reduced odds of progression to 
severe disease (requiring non-invasive ventilation, high-flow 
oxygen, intubation and mechanical ventilation) or death in the  
ITT population (72% reduction; p=0.064) that became significant 
in the PP population (82% reduction; p=0.041).

•  Patients who received SNG001 were more than twice as likely 
to recover (defined as ”no limitation of activities” or “no clinical 
or virological evidence of infection”) over the course of the 
treatment period compared to those receiving placebo in both 
the ITT population (HR 2.19; p=0.043) and the PP population  
(HR 2.29; p=0.033).

•  Over the treatment period, patient-reported Breathlessness 

Cough and Sputum Scale (BCSS) and in particular breathlessness 
scores were markedly reduced in patients who received SNG001 
compared to those receiving placebo (p=0.026 for BCSS and 
p=0.007 for breathlessness).

•  Three subjects (6%) died after being randomised to placebo. 
There were no deaths among subjects treated with SNG001.

Other findings included:

•  The median duration of COVID-19 symptoms at the 

point dosing commenced was 10 days. This goes against 
conventional wisdom with IFN-beta usage, where efficacy is 
expected based on early use. If treatment is administered 
to hospitalised patients after 10 days of illness, then this 
is late in terms of time (because the patient has been 
ill for 10 days) and late in terms of illness severity.  

•  Odds ratios for improvement, recovery and hospital discharge 

were in favour of SNG001 at day 28 suggesting that the 
treatment effect extends beyond the end of the dosing period. 
A treatment that accelerates full recovery may be especially 
relevant to patients with COVID-19 who experience wide-ranging 
long-term symptoms for at least a month and sometimes longer 
(known as Long COVID or Long-haul COVID).

•  SNG001 was well tolerated.

Strategic Report 
(continued)

SG016: Home Cohort
In April 2020, Synairgen received approvals to extend the SG016 
trial into the home environment, with the objective of initiating 
dosing earlier in the infection cycle of COVID-19 to prevent 
severe lower respiratory tract symptoms. The trial recruited 
patients who were either aged over 65, or over 50 with a high-
risk comorbidity. Patients must have had symptoms for less 
than eight days. The trial was fully recruited in January 2021. 

The Home Cohort trial involved SNG001 (or placebo) being 
delivered to eligible participants by couriers observing appropriate 
social distancing measures. In order to minimise risks to patients 
and healthcare workers in this setting, all visits were conducted 
remotely by video link. If positive for SARS-CoV-2, the drug (placebo 
or SNG001), aerosol delivery device, and other trial equipment 
were despatched to the patient. Each dose was taken under video 
supervision. Safety and efficacy endpoints were also assessed 
during the video calls.

The study confirmed the feasibility of rapid roll-out of antiviral 
treatment in the context of a pandemic, where there is a need to 
limit the movement of people to minimise risks to patients, the 
public and healthcare providers.

The top-line results from the Home Cohort and combined data for 
the whole SG016 trial were announced in April 2021 and the key 
findings were:

•  The vast majority of Home Cohort patients experienced mild 

disease – only two patients were hospitalised due to worsening 
of COVID-19 during the treatment period, both on placebo.

•  Home Cohort patients successfully self-administered SNG001.

•  Encouraging pattern of recovery and reduction in breathlessness 
in SNG001-treated patients compared to placebo in those with 
marked or severe breathlessness at the start of treatment.

•  A combined analysis of the Hospital and Home Cohorts data 
was conducted to explore the impact of the different levels of 
breathlessness, which is one of the most prominent symptoms 
of COVID-19, on time to recovery. 

•  An assessment of only those patients on placebo indicated 
that those with marked or severe breathlessness at time of 
treatment initiation had slower recovery to “no limitation of 
activities” than those patients who were not as breathless. This 
is a strong indicator of those patients who should be selected 
for treatment with SNG001.

•  In the Hospital Cohort (reported in July 2020) patients were 

2.19 times more likely to recover to level 1 on the Ordinal Scale 
compared to placebo, HR 2.19; p=0.043. The addition of the 12 
markedly and severely breathless Home Cohort patients further 
improves the Hazard Ratio to 2.49; p=0.009. 

•  Interestingly, not all hospitalised patients were markedly or 

severely breathless at time of treatment initiation. An analysis 
including only patients who were markedly or severely 
breathless at the time of treatment initiation, irrespective of 
whether they were in hospital or at home, showed that those 
treated with SNG001 (n=33) were 3.41 times more likely to 
recover than those on placebo (n=36) (HR 3.41; p=0.004). This 
further underlines the potential benefit of SNG001 for patients 
identified as breathless.

The data from the Home Cohort and the combined data analysis 
showing the potential importance of breathlessness as a 
stratification tool to identify patients most likely to benefit from 
SNG001 is invaluable. We now know better who not to treat and 
who to treat. Fortunately, when we designed the Phase III clinical 
trial, we selected patients most likely to be breathless and these 
data make us feel more confident of a positive outcome.

COVID-19 Phase III trial – SG018
Synairgen’s global Phase III “SPRINTER” clinical trial in hospitalised 
COVID-19 patients, SG018, is a randomised, placebo-controlled 
study being conducted in 17 countries enrolling a total of 610 
COVID-19 patients who require supplemental oxygen (i.e. they are 
by definition more likely to have marked or severe breathlessness). 
After reporting the results for the primary and secondary endpoints 
of the study, enrolled patients will continue to be assessed for  
Long COVID symptoms.

In October 2020, Synairgen appointed Parexel Biotech, a division 
of the leading global clinical research organisation, Parexel, to help 
conduct the Phase III trial. The trial is deemed an Urgent Public 
Health study by the UK’s National Institute for Health Research 
(NIHR). In the US, SNG001 has been granted Fast Track status from 
the US Food and Drug Administration (FDA).

There are two primary endpoints: ‘time to recovery to “no limitation 
of activities” up to Day 28’; and ‘time to hospital discharge’. In addition, 
there are secondary endpoints relating to changes in OSCI score 
and symptoms, especially breathlessness, and Long COVID.  
There will also be a safety assessment. 

First patient dosing commenced in the UK in January 2021, where 
the regulators were familiar with SNG001. The trial is now approved 
by regulators in 11 additional countries, with further approvals 
expected in five more countries in the coming weeks. Initial trial 
results are expected in H2 2021.

US NIH ACTIV-2 trial
In January 2021, Synairgen announced signature of a clinical 
trial agreement to include SNG001 in the ACTIV-2/A5401 
Phase II/III trial in patients with COVID-19 not yet requiring 

hospitalisation. This is a government-funded trial sponsored 
by the US National Institute of Allergy and Infectious Diseases 
(NIAID), part of the US National Institutes of Health (NIH). NIH’s 
ACTIV (Accelerating COVID-19 Therapeutic Inventions and 
Vaccines) is a public-private partnership to develop a coordinated 
research strategy to speed up the development of the most 
promising treatments and vaccine candidates for COVID-19. 
ACTIV-2 is a master protocol designed for evaluating multiple 
investigational agents compared to placebo in adults with 
mild-to-moderate COVID-19, not requiring hospitalisation.

The Phase II/III study is an adaptive, randomised, blinded, 
placebo-controlled trial which commenced patient dosing in 
February 2021. The Phase II evaluation of inhaled interferon 
beta will see the recruitment of up to a maximum of 220 
participants across US sites in home-based settings. A positive 
result enables progression into the Phase III stage of the study. 

As in the case with the Home Cohort of Synairgen’s Phase II study, 
the inclusion in another home-based trial reflects the ease of use 
that inhaled treatments offer, making it possible for patients to 
self-administer treatment at home with professional supervision, 
reducing the risk of virus transmission during hospital visits and 
reducing pressure on healthcare systems. At-home treatments also 
have the potential to be taken earlier in the course of the illness, 
preventing the progression of the virus in the lower respiratory 
tract and the concomitant risk of hospitalisation, which could 
be of very significant benefit if hospitals are overstretched.

Manufacturing and Delivery of SNG001 
In preparation for gaining approval for inhaled interferon 
beta, the Company announced deals in October with 
Akron Biotechnology and Catalent Biologics.

Akron Biotechnology is manufacturing inhaled interferon beta 
drug substance to meet clinical and commercial demand. 

Catalent Biologics is a leading global provider of advanced 
development and manufacturing solutions for drugs and 
biologics, and is supporting the inhaled interferon beta fill/
finish at its Brussels, Belgium facility, where it is conducting 
manufacturing scale-up of the drug candidate into pre-
filled syringes. The Company is also evaluating blow fill 
seal technology as an alternative to glass syringes. 

Synairgen is collaborating with Aerogen, a leader in high-
performance aerosol drug delivery in the acute care setting. 
Aerogen is providing the Aerogen Solo/Ultra aerosol delivery 
system, which is already widely used in hospitals in the EU and 
US, for delivery of SNG001 directly into the lungs of patients.

Strategic Report  
(continued)

Managed Access Program
In September 2020, Synairgen put in place a Managed Access 
Program facility with Clinigen to enable physicians in the 
UK and EU to access SNG001 for hospitalised patients.

Chronic Obstructive Pulmonary Disease (COPD) 
COPD is a progressive lung disease, punctuated by periods of 
exacerbation characterised by acute worsening of symptoms which 
require treatment with oral corticosteroids and/or antibiotics, which 
have major implications for both the patient and the healthcare 
system. Worldwide, COPD affects approximately 384 million 
people3 and is the third leading cause of death according to the 
World Health Organisation.4 COPD exacerbations are the second 
most common cause of unplanned hospitalisation in England.5

COPD trial – SG015
In 2018, Synairgen commenced a two-part COPD trial (SG015) 
to assess the safety and lung antiviral biomarker and efficacy 
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 and in addition to look at lung function. Recruitment 
into the trial commenced in earnest in January 2019 and 
was progressing well until the emergence of COVID-19.

Impact of COVID-19 on SG015 programme

COVID-19 made it difficult to dose COPD patients in trial units 
without potentially exposing vulnerable patients and research staff 
to SARS-CoV-2. Hence in March 2020 the trial was paused (now 
stopped), with 109 out of the targeted 120 patients recruited. 
MHRA approval was then received to run an interim analysis on 
the grounds that the data from COPD patients with confirmed 
viral infection could generate useful safety, biomarker and efficacy 
data to support ongoing trials of SNG001 in COVID-19 patients.

Results of interim analysis of SG015 trial in COPD patients

On 8 September 2020, Synairgen announced a positive interim 
analysis of SNG001 in COPD patients, supporting progression of 
SNG001 in COVID-19. Key findings included:

•  SNG001 was well tolerated during the treatment period in a study 
population that was elderly (mean age 66 years) and suffering 
from reduced respiratory function, as measured by forced 
expiratory volume in one second (FEV1) (59% of predicted value).

•  The percentage of on-treatment adverse events was similar in 

the placebo and SNG001 treatment groups (48.1% versus 45.6%, 

respectively), with treatment-related adverse events being more 
frequent in the placebo group (25%) compared to the SNG001 
group (15.8%).

•  Over the treatment period, lung antiviral responses to 
viral infection were significantly enhanced in patients 
receiving SNG001 compared to those on placebo, as 
assessed by measuring increases in the gene expression 
of interferon beta-dependent antiviral biomarkers MX1 
(p=<0.001) and OAS1 (p=<0.001) in lung (sputum) cells.

•  The impact of viral infection on COPD patients in the trial was 

most evident on peak expiratory flow rate (PEFR), a measure of 
lung function, and patient-reported symptoms assessed using 
the Breathlessness Cough and Sputum Score (BCSS), and was 
particularly apparent in exacerbating patients (i.e. patients 
already requiring treatment with oral corticosteroids and/or 
antibiotics at the time of randomisation, who represented one 
third of patients enrolled).

•  Exacerbating patients who received SNG001 had significantly 

better lung function during the treatment period (difference in 
change from baseline morning PEFR between patients receiving 
SNG001 and placebo over days 2-15 was 25.5L/min; p=0.041).

•  Although there was no significant difference in total BCSS in 
this group over the treatment period, there was a trend for 
the breathlessness component of the score in exacerbating 
patients, suggesting that these patients may have recovered 
more rapidly if they received SNG001 rather than placebo.

•  Viral infections had less impact on non-exacerbating 

patients and there were no significant treatment effects.

The trial data is supportive of not only the near term COVID-19 
development activity, but also the longer term aim to use SNG001 
to treat patients admitted to hospital with severe viral lung 
infections. COPD patients represent one of the largest groups  
of patients in this setting.

LOXL2 
Pharmaxis, the Company’s Australian-based partner for the 
antifibrotic LOXL2 inhibitor programme, updated the market post 
period-end on 30 April 20216 to state it is currently pursuing a 
number of different options to enable PXS-5382 to enter the clinic 
in Phase II trials in a chronic kidney disease. Pharmaxis also states 
that it continues to have discussions with potential partners and 
independent investigators in relation to study protocol design 
and funding options including grants. In the event of a qualifying 
licensing agreement or other commercialisation of the product, 
Synairgen is entitled to receive circa 17% of Pharmaxis’ licence 
receipts/royalties, net of allowable expenses and we have no 
ongoing financial obligations to the programme.

Intellectual Property

Patent filings
Adding to the Company’s IP portfolio, patent applications were 
filed following (i) the results from the study for the use of inhaled 
IFN-beta in COVID-19 patients and (ii) the interim analysis of 
the data from the trial that used inhaled IFN-beta to treat virus-
induced exacerbations in COPD patients undergoing treatment 
with systemic corticosteroids. Further updates regarding pending 
patents will be provided in due course.

Addition to the management team
Richard Hennings joined Synairgen as Chief Commercial Officer 
in March 2021. Between 1999 and 2017 he held Commercial 
leadership roles at Gilead Sciences, Novartis and AstraZeneca. 
During his eight-year Gilead tenure, Richard led the expansion 
of respiratory and anti-viral portfolios in the EU and US markets, 
launching inhaled Cayston® for Cystic Fibrosis and HIV treatment 
Stribild®. During his subsequent AstraZeneca assignment, 
Richard led Antibiotic Zavicefta® EU/ LATAM launch readiness and 
divestment of the antibiotics business unit to Pfizer. Between 2017 
and 2020 Richard was VP & Commercial Head of Verona Pharma.

Key Performance Indicators (KPIs)
The Board considers that the most important KPIs are non-
financial and relate to the progress of the clinical programmes and 
the scale up of SNG001 manufacturing, which are discussed in the 
preceding sections of this report.

The most important financial KPIs are the planned expenditure 
on COVID-19 related clinical trials and manufacturing scale-up 
and the cash position of the Group. The actual expenditure on 
the COVID-19 activities 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 37 to 52. The consolidated financial statements are 
prepared in accordance with international accounting standards 
in conformity with the requirements of the Companies Act 2006.

The financial statements of the Company, set out on pages 53 to 
57, 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 2020  
was £17.74 million (2019: £4.82 million) with research and 

development expenditure amounting to £15.50 million  
(2019: £3.46 million) and other administrative expenses  
£2.25 million (2019: £1.36 million).

During 2019 our research and development activities were solely 
focussed on the Phase II trial in COPD patients. During 2020 we 
continued to work on the COPD trial until it was halted on account 
of COVID-19. However, the majority of the £12.0 million year-
on-year increase in research and development expenditure is 
attributable to our COVID-19 clinical trials and manufacturing  
scale-up activities. 

Clinical trial expenditure was initially focussed on the SG016 
hospital and home Phase II trial activities. This was followed by 
preparatory activities for the international SG018 Phase III trial in 
hospitalised patients and finally for participation in the ACTIV-2 
study, where we have provided study product for the trial. The 
clinical trial preparatory and execution activities necessitated a 
very significant scale up of our clinical trial infrastructure and this 
resulted in a much greater use of outsourced experts. 

Significant investment was made into manufacturing scale-
up. Two batches of active and placebo pre-filled syringes were 
manufactured to meet clinical trial requirements. Process 
Performance Qualification (PPQ) preparation activities (in advance 
of commercialisation) were commenced at both a new drug 
substance manufacturer and at a new drug product manufacturer, 
with the latter involving both pre-filled syringes and blow-fill-seal 
ampoules. The Company’s advisory base in both regulatory and 
CMC activities was also significantly expanded.

Other administrative expenses increased from £1.36 million to 
£2.25 million. The increase was attributable to higher personnel 
costs, as we scaled up to handle greater volumes of transactions, 
higher investor relations activity costs, and the costs of hedging 
an element of our future foreign exchange exposures on 
manufacturing costs denominated in US dollars and Euros.

Despite the significant increases in cash on hand after the two 
fundraisings during the year, finance income reduced on account of 
the reduction in interest rates during the period. Finance expense 
relates to interest expense on lease liabilities and the increase 
reflects the first full year of interest expense, due to the lease 
signed in mid-2019 being the first to be accounted under IFRS 16.

The research and development tax credit increased from  
£0.91 million to £3.82 million on account of the increased  
qualifying expenditure. The credit equates to 25% of our 2020 
research and development expenditure (2019: 26%).

The loss after tax for 2020 was £13.92 million (2019: £3.89 million) 
and the basic loss per share was 9.46p (2019: basic loss per  
share of 3.55p).

Strategic Report  
(continued)

Fundraisings
During 2020, two fundraisings were conducted to fund our 
ongoing COVID-19 clinical and manufacturing activities. 

•  Share issue proceeds (net of costs): £97.89 million (2019: £nil);

•  Net settlement of options £1.29 million (2019: £nil); and

•  Lease payments: £0.21 million (2019: £nil).

The first of these, conducted in March 2020, raised £14 million 
(before expenses) by the issue of 40 million ordinary shares at 
a price of 35p per share to fund: COVID-19 clinical trial activity; 
manufacturing of SNG001 drug product and other supply 
chain considerations; and strengthen the balance sheet.

The second fundraising took place in October 2020 and raised 
£87.07 million (before expenses) by the issue of 49.75 million 
ordinary shares at a price of 175p per share. 45.71 million shares 
were issued pursuant to an institutional placing and 4.04 million 
shares on account of a fully subscribed Open Offer. The proceeds 
were raised to fund: the Phase III trial in COVID-19 patients; 
SNG001 manufacturing and device scale-up activities; the 
generation of further data to support SNG001 clinical development, 
manufacturing processes and regulatory activities; strengthening 
the balance sheet; and the net settlement of option costs.

Statement of Changes in Equity
In addition to the net proceeds from the share issues, the 
recognition of share-based payments and the loss after taxation, 
a charge of £1.29 million was taken to reserves in respect of net 
settled options for the year ended 31 December 2020 (2019: 
£nil). At the time of the second fundraising, two of the executive 
directors exercised options over some 1,176,334 ordinary shares. 
The Company net settled by paying the income tax and NICs 
on the option holders’ behalf and issuing 534,172 new ordinary 
shares. The cost of the income tax and NICs paid by the Company 
amounted to £1.29 million and, in accordance with IFRS 2, was 
charged directly to reserves as it equated to the fair value of the 
number of shares withheld by the Company.

Statement of Financial Position  
and Cash Flows
At 31 December 2020, net assets amounted to £85.14 million 
(2019: £2.25 million), including cash balances of £74.98 million 
(2019: £2.45 million).

The principal elements of the £72.53 million increase during the 
year ended 31 December 2020 (2019: £2.88 million decrease) in 
cash balances were:

•  Cash used in operations: £24.73 million (2019: £3.73 million);

•  Research and development tax credits received: £0.91 million 

(2019: £0.84 million);

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

•  Current tax receivable increased from £0.87 million to  
£3.77 million on account of the higher research and  
development tax credit;

•  Trade and other receivables increased from £0.14 million to 
£9.37 million. Prepayments and accrued income increased  
from £0.10 million to £8.82 million on account of manufacturing 
and clinical trial prepayments. VAT recoverable increased from 
£0.04 million to £0.55 million on account of higher transactional 
values; and

•  Trade and other payables increased from £1.49 million to  

£3.28 million, reflecting  the increased level of activity.

Section 172 statement
In accordance with section 172(1) ((a) through (f)) of the 
Companies Act 2006, the directors have acted, both 
individually and collectively, in a way that would be most likely 
to promote the success of the Company for the benefit of its 
members as a whole. The directors have regard (amongst 
other matters) to the:

a) 

likely consequences of any decision in the long-term;

b) 

interests of the Company’s employees;

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

suppliers, customers and others;

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

and the environment;

e)  desirability of the Company maintaining a reputation for 

high standards of business conduct; and

f)  need to act fairly between members of the Company.

The following table, in combination with the Corporate 
Governance Statement set out on pages 19 to 22 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.

•  Business strategy
•  Operational performance
•  Financial performance and  

cash requirements
•  Corporate Governance

•  RNS announcements
•  Website updates
•  Meetings after preliminary statement release 

and interims for institutional investors

•  AGM
•  Proactive investor interview

Employees
Synairgen has 22 employees (including executive 
directors) who are multi-skilled and many 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.

•  Operational targets  

and progress

•  Regular full company meetings and  

a policy of open disclosure

•  Opportunities to share ideas
•  Financial resources of the Group
•  Share price
•  Working time flexibility

•  Team meetings
•  Open door policy to executive directors
•  Structured appraisal process
•  Use of share-based incentives for employees

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.

•  Operating facilities
•  Intellectual property
•  Joint projects
•  Published papers

•  Meetings with Founders
•  Interaction on projects with scientists  

and clinicians

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

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 continue to 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 which governments will buy for 
stockpiling and it is therefore critical that there is an 
identified market need in the community.

•  Supplier product  

development plans

•  Our clinical trial and longer-term 

development needs

•  Regular project meetings

•  Programme development plans,  
including clinical trial designs

•  Regular meetings at key respiratory 

conferences (ATS, ERS)

•  Clinical trial read-outs
•  In-house and external 
competing products

•  New therapeutics development
•  Involvement in clinical trials

•  Interactions with clinicians
•  Patient data from clinical trials

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

•  Clinical trial approvals
•  Regulatory compliance

•  Use of external consultants to make  

sure we are complying with regulations

•  Interactions with Ethics Committees, MHRA, 
FDA, EMA and other regulatory agencies

Strategic Report  
(continued)

Principal decisions in 2020
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 five key 
decisions taken during the year fall into this category and were 
made with full consideration of both internal and external 
stakeholders.

•  The decision to undertake the SG016 clinical trial in 

hospitalised and home-based COVID-19 patients and  
raise £14 million (before expenses).

•  The decision to raise £87 million (before expenses)  

to undertake a Phase III trial in hospitalised COVID-19 
patients and to scale up manufacturing capacity.

•  The decision to source a new drug substance manufacturer 
for SNG001 and to scale up manufacture of drug substance 
and drug product prior to any marketing authorisation 
being received.

•  The decision in respect of primary and secondary  

endpoints to be measured in the Phase III clinical trial.

•  The decision to proceed with a twin track strategy of 
progressing both pre-filled glass syringe and blow fill  
seal technologies for the ‘Fill and Finish’ element of drug 
product manufacturing.

Principal risks and uncertainties
In addition to the fact that the Group has one lead candidate 
(SNG001), albeit with a number of indications, and is therefore 
dependent on there being a successful outcome to its 
development, the Board considers that the principal risks and 
uncertainties facing the Group may be summarised as follows:

•  Pre-clinical testing and/or clinical trials fail to  
  generate positive data

There is a high failure rate in the development of 
pharmaceuticals and there is a substantial risk of adverse, 
undesirable, unintended or inconclusive results from pre-
clinical testing or clinical trials, which may substantially 
delay, halt entirely or make uneconomic any further 
development of SNG001 (whether in the indication 
of COVID-19 or in others) and may prevent or limit its 
commercial use.

•  Clinical trials overrun

There are a number of factors which may lead to delays, 
including but not limited to: (i) delays to regulatory 
approvals; (ii) variations in labelling and other regulatory 

requirements between countries; (iii) dealing with protocol 
changes; (iv) difficulty in finding suitable sites and patients; 
and (v) incidence of COVID-19 declining or resolving.

If any of the above circumstances or events occur, then 
delays may impact the Phase III timetable, which in turn may 
also have cost and/or ultimately commercial implications.

To mitigate this risk, the Group monitors the prevalence of 
COVID-19 on a country-by-country basis and has regular 
meetings with its outsourced Clinical Research Organisation 
(CRO) to expedite the set up and execution of the trial on a 
local level.

•  The regulatory approval processes of the MHRA, EMA, FDA  
  and other comparable regulatory agencies may be lengthy,  

time-consuming and unpredictable
The Group’s future success is dependent upon its ability 
to develop successfully, obtain regulatory approval for and 
then successfully commercialise SNG001. Even if SNG001 
is successful in clinical trials, there can be no assurance it 
will receive regulatory approval at all or in a timely manner. 
A drug which has received approval in one territory may 
not succeed in getting approval in other territories and 
regulators in different jurisdictions may seek different 
criteria and endpoints in order for regulatory approval 
and marketing authorisations to be granted. In the event 
of COVID-19 resolving, regulators may take a different 
approach to regulatory approval for any new therapeutics, 
which may increase the regulatory burden on the Group  
and have both time and cost implications.

The Group takes the advice of specialist regulatory advisers 
and maintains an on-going dialogue with regulators.

•  Coverage and reimbursement

Significant uncertainty exists as to the coverage and 
reimbursement status of any pharmaceutical or biological 
products for which the Group may obtain regulatory 
approval. In the United States and other countries, patients 
who are prescribed treatments for their conditions and 
providers performing the prescribed services generally 
rely on third-party payors to reimburse all or part of the 
associated healthcare costs. Patients are unlikely to use 
the Group’s products unless coverage is provided and 
reimbursement is adequate to cover a significant portion of 
the cost of our products. Sales of any products for which the 
Group receives regulatory approval for commercial sale will 
therefore depend, in part, on the availability of coverage and 
adequate reimbursement from third-party payors. Third-
party payors include government authorities, managed care 
plans, private health insurers and other organisations.

•  There are a number of competing COVID-19 therapeutics 

at different stages of regulatory approval

There are a number of competing therapeutics for COVID-19 
at varying stages of regulatory approval, which may be 
brought to market more quickly than SNG001 or prove 
to be more effective, desirable or cheaper. Many of the 
Group’s competitors have substantially greater financial and 
other resources. There can therefore be no assurance that 
competitors will not succeed in developing products which 
would render SNG001 non-competitive or obsolete.

•  Synairgen is dependent on a small team of key personnel  
  and scientific and clinical collaborators

The Group’s success is highly dependent on the expertise 
and experience of a small team of key personnel and 
scientific and clinical advisers/contractors. Whilst 
the Group has entered into employment and other 
agreements with each of these key personnel, the 
retention of such personnel cannot be guaranteed. 
Should key personnel leave or no longer be party to 
agreements or collaborations with the Group, the 
Group’s business prospects, financial condition and/
or results of operations could be adversely affected. 

To mitigate this risk, the Group has contracted with 
certain key partners to provide services to the Group, 
including CRO services, regulatory affairs consultants, 
CMC consultants and clinical management services. In 
the event of positive Phase III trial results, it is likely that 
the Group will have to consider partnering with other 
organisations in order to scale up its operations particularly 
in respect of marketing and distribution activities. There 
can be no guarantee that the Group will find suitable 
partners or on commercially advantageous terms.

•  Manufacturing complexity

SNG001 is a biological product with inherent batch to batch 
variation. Manufacturing issues could substantially increase 
our costs and limit supply of SNG001 for clinical trials and 
commercial sales.

•  The Group is dependent on third party supply,  
  manufacturing and clinical service relationships

In common with other drug developers of similar size, 
the Group engages the expertise and resources of third 
parties in a number of key areas including: (i) the conduct 
of clinical trials (Parexel); (ii) the manufacture, scale-
up, fill/finish and supply of SNG001 (Rentschler, Akron 
Biotechnology and Catalent); and (iii) the manufacture and 
supply of the nebuliser (Aerogen). Critical and complex 

aspects of the Group’s business, some of which are 
being scaled up for the first time and progressed to meet 
accelerated timelines as a result of COVID-19, are therefore 
in the hands of third parties over whom the Group has 
limited control. The Group cannot guarantee that those 
third parties or their suppliers (including suppliers of raw 
materials and components necessary for manufacturing 
activities) will be able to perform their contractual and 
regulatory obligations satisfactorily or on time.

Default, delay, non-compliance with law and regulation 
or other sub-optimal performance by a third party 
may adversely affect the Company’s ability to carry out 
the Phase III trial and/or deliver production in a timely 
and cost-effective manner, which would adversely 
affect the Group’s business plans and prospects.

Regulatory requirements for pharmaceutical products 
tend to make the substitution of counterparties 
costly and time-consuming. Alternative suppliers 
may not be able to manufacture products effectively, 
on time or obtain the necessary manufacturing 
licences from applicable regulatory authorities.

The Group seeks to minimise risk by holding regular 
meetings with key suppliers and the use of project 
managers and other consultants to manage the 
relationships. Where possible the Group tries to 
have more than one supply route – for example 
it is pursuing both pre-filled syringes and blow fill 
seal technology for the finished dosage form.

•  Intellectual property

The commercial success of the Group depends on its 
ability to obtain patent and other protection for its 
pharmaceutical discoveries in the US, Europe and elsewhere 
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 products. Litigation 
may be necessary to protect the Group’s intellectual 
property, which may result in substantial costs.

Strategic Report  
(continued)

Synairgen’s
Founders 

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.

•  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 equity capital. The Group may not 
be able to generate positive net cash flows in the future or 
attract such additional funding required on suitable terms, 
or at the time it is needed. In such circumstances, the 
Group’s 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.

•  Cyber attack or IT systems failure

The Group is at risk of cyber attack or IT systems failure to 
it or its key suppliers, 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.

Outlook
Trial readouts are due over the coming months which we 
anticipate will add to the growing body of evidence supporting 
the use of inhaled interferon beta as a potential treatment 
for patients with COVID-19. These include data from our 
international SG018 Phase III trial and the US ACTIV-2 Phase 
II trial in COVID-19 outpatients, with initial data for SG018 
expected in H2 2021. Beyond these trials Synairgen is in 
regular dialogue with government bodies and companies 
regarding the progress of inhaled interferon beta and its 
application as an effective treatment in both hospitalised  
and home-based patients. 

In the second half of 2021 Synairgen will continue its 
commercialisation and manufacturing plans in order to scale 
up manufacturing and supply capacity, with the aim of making 
the drug readily available internationally and to meet potential 
commercial demand in the event of a regulatory approval.

On behalf of the Board.

Corporate Governance Statement

The Board of directors of the Company (the “Board”) is 
accountable to the Company’s shareholders for good corporate 
governance and it is the objective of the Board to attain and 
maintain 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 seek to 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 2021 we undertook a formal Board performance review, 
building on the initial formal review conducted in 2019.

Board of Directors
On 31 December 2020, the Board consisted of myself, as the non-
executive Chairman, three executive directors (Richard Marsden, 
Dr Phillip Monk and John Ward), and three non-executive directors 
(Iain Buchanan, Dr Bruce Campbell and Prof. Sir Stephen Holgate).

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  
pages 17 and 18. 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 several 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 set 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 clinical trials, particularly with reference to biomarker 
and statistical analysis. Phillip regularly interacts with expert 
advisers/KoLs and attends key relevant medical conferences.

John Ward
John is a Chartered Accountant who has worked for more than 
20 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 and  
the ICAEW.

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 several 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 several other 
life sciences companies either as a director or consultant.

Prof. Sir 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 capital markets 
experience from other companies. The Board has expertise in 
the following key areas: capital 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 the current phase of its strategy. 
However, in due course as the business evolves, the Board  
would seek to further enhance its experience in certain areas.  
The Board is still composed solely of males and recognises this 
gender imbalance. Over ensuing periods, the Board will look to 
enhance its composition appropriately.

On 18 January 2021, Simon Holden was appointed as Company 
Secretary, fulfilling the role previously carried out by John 
Ward. Simon is a corporate lawyer by background and fulfils 
the role of secretary for several other quoted companies, on 
both the Main Market and AIM. The Company Secretary 
reports directly to the Chairman on governance matters.

Non-executive directors are required to attend six 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. It is anticipated that enhancements to Board 
composition over the coming periods will result in greater 
QCA Code compliance in respect of director independence.

The Board also notes that one of its non-executive directors 
was granted options in 2010, which lapsed in 2020. The practice 
of granting non-executive directors options has now ceased. 

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 for the directors 
and that, in the case of the non-executives, they are considered 
by shareholders as remaining functionally 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. 
Scheduled Board meetings take place throughout the year and the 
Board also meets on any other occasions it considers necessary. 
During the year ended 31 December 2020, the Board met six times 
for Scheduled Board meetings, with all members in attendance. 
At each meeting there was an opportunity for non-executive 
directors to discuss matters without executive directors present.

In addition, there were 13 other meetings, 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 
March 2021. 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, had not been feasible 
to date. However, it was agreed to review Board composition over 
the coming period including from the perspective of Diversity and 
Inclusion. It was also agreed that given the significant developments 
of the previous year and the speed with which the approach to 
COVID-19 had to operate, there had been little time for the Board’s 
annual strategy review. This too, will be held in the coming period. 

Also, during March 2021, 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.

Corporate Governance Statement
(continued)

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

During 2020, the committee met six times with all 
members attending. The Directors’ Remuneration 
Report is detailed on pages 23 to 27.

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, without affecting their 
Audit Independence). 

During 2020, the committee met three times with all members in 
attendance. The Audit Committee Report is detailed on page 28.

Remuneration and Nomination Committee
The Remuneration and Nomination Committee currently 
comprises Iain Buchanan (Chairman), Dr Bruce Campbell 
and Simon Shaw. 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. 

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 Sir 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 Board.

Business model and strategy
As detailed in the Strategic Report on page 5, Synairgen’s strategy 
is to develop SNG001 as a broad-spectrum antiviral by conducting 
a Phase III study and preparing for launch. 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:

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 13 to 15. 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. A Health and Safety report  
is reviewed by the Board.

Simon Shaw 
Chairman

11 May 2021

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.

•  Passion – to demonstrate a passion for delivering high  

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

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.

•  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.

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.

2020 was a transformative year for the Group with considerable 
progress on its drug pipeline including its SNG001 treatment for 
COVID-19. The Group also raised some £101 million of new capital 
and its share price rose over the year from 6p to 153p. Both the 
executives and the wider workforce were critical to the delivery 
of these exceptional results and, after many years of providing 
modest fixed pay due to affordability constraints, the Remuneration 
Committee reviewed pay both for the executives and the wider 
workforce. For completeness, no staff were made redundant or 
placed on furlough.

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 pages 21. The members of the Committee are Iain Buchanan 
(Chairman), Dr Bruce Campbell and Simon Shaw. 

The Committee, which is required to meet at least twice a year, met 
six times during the year ended 31 December 2020 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 9% 
pension contribution (which has been frozen as explained in 
this report) either to the executive director’s individual money 
purchase scheme or, 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 and typical benefits including family 
private health cover, permanent health and life assurance. 

The previous salary and benefit review took effect 
from 1 January 2020, at which point the executive 
directors’ salaries were increased by 2% (in line with 
or below the level awarded to staff generally).  

During the year, a benchmarking exercise was undertaken across 
the workforce. Salaries and benefits have therefore been reviewed 
with effect from 1 January 2021, taking into account Group and 
individual performance, external benchmark information and 
internal relativities. As a consequence of the 2021 review, executive 
director salaries were increased by 12%, which was consistent 
with the level awarded to staff generally. Given the significant 
accomplishments made in 2020, this award is considered merit-
based and modest when benchmarked against equivalently 
sized companies, demonstrating that the Committee is being 
conscious of the need to both show restraint and ensure that 
colleagues are appropriately but not excessively paid in a sector 
currently subject to intense skills shortages. It, therefore, plans 
to keep all salaries and packages under review and may make an 
interim award if it considers that to be necessary or appropriate.

Recognising the increased focus on pension provision, the 
Committee decided that the level of pension provision should 
be frozen with the current 9% contribution level only applying 
to the pre-2021 salary levels. This will be reconsidered as part 
of subsequent reviews. If the recipient takes cash in lieu of a 
contribution to a registered pension, the amount payable is 
reduced to ensure that the total cost to the employer (inclusive  
of employers’ NICs) is not increased.

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

Directors’ remuneration for the year ended 31 December 2020 is 
set out on page 27 of this document.

(ii) Chairman and non-executive director remuneration
No changes have been made to the fees set out in last year’s  
report which remain a fee payable to the Chairman of £45,000 
per annum, a fee for the non-executive directors of £25,000 and 
a fee of £5,000 will continue to be paid to non-executive directors 
who chair either the Audit or Remuneration and Nomination 
committees. The Chairman continues to waive 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 within an overall cap of 100% 
of salary. Given the exceptional achievements including the 
conducting of the COVID-19 clinical trial, manufacturing scale up 
activities and significant fundraisings, as reflected by the share 
price increasing some twenty-five fold, the Committee awarded  
the maximum opportunity of 100% of salary.

Bonuses in respect of 2020 will be paid in H1 2021.

(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 LTIP, 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 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 
June 2020 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 100% of salary with 
performance conditions as set out below. 

The Committee intends to make a similar LTIP award (the 2021 
award) during the six week period following the preliminary 
announcement of the results for the year ended 31 December 
2020, with each of Richard Marsden, Phillip Monk and John Ward 
being granted awards over shares worth up to 100% of salary with 
vesting and performance conditions similar to the 2020 LTIP award. 

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. Each of the 
executive directors has achieved this level.

All awards will lapse at the end of the applicable performance 
period to the extent that the applicable performance 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.

Directors’ Remuneration Report 
(continued)

Performance conditions for the 2018, 2019 and 2020 LTIP awards
The performance conditions for all three 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 
shareholder over the performance period in terms of change in 
the share price and assuming re-investment of any dividends in 
more shares at the prevailing price on the relevant ex-dividend 
date) of the Company over the three year performance period is 
equal or greater than the percentage increase in the techMARK 
mediscience™ index over the same period as follows: 

TSR growth over the performance 
period less percentage increase in the 
techMARK mediscience™ index over the 
same period

Less than 10%
10%
20% 
30% 
Performance between the steps

Vesting percentage  
of total number of shares  
subject to award

0%
25%
50%
100%
Pro-rata on a straight-line basis

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%.

Post period-end, the 2018 LTIP award vested in full.

TSR Performance
The latest guidelines from the QCA encourage companies to 
include a chart showing its TSR performance over the preceding

(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. In 
February 2021, Richard Marsden’s notice period was amended 
from six months to twelve months from either party.

During the year ended 31 December 2020, 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:

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 and 
2010 awards and the Committee agreed to extend the exercise window until the end of 2020.

Note 2. The Company issued (i) 40,000,000 new shares pursuant to a placing on 30 March 2020 and 15 April 2020 and (ii) 49,753,026 new shares pursuant to  
a further placing on 19 October 2020 and 4 November 2020. While this would have permitted the Committee to adjust the shares subject to awards using the 
HMRC established Theoretical Ex-Rights Price (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.

Options over 1,176,334 shares granted under the LTIP were exercised during the year by Richard Marsden and John Ward. The Company 
agreed to net-settle these options on behalf of Richard Marsden and John Ward. Under this process, the Company settled the relevant 
options by delivering 534,172 ordinary shares (386,842 to Richard Marsden and 147,330 to John Ward), which represented the notional gain 
on exercise with the income tax and National Insurance Contributions (NICs) due on such gain paid by the Company to HMRC on behalf of 
Richard Marsden and John Ward. Richard Marsden and John Ward did not receive any cash proceeds from the exercise of these options.

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 2020 was 153.0p. During the year then ended, the mid-market price 
ranged from 5.875p to 247.52p. On 11 May 2021 the closing price was 102.2p.

(i)  Richard Marsden was the highest paid director during the year ended 31 December 2020, earning a total of £415,000 as set out above. In addition,  

he made a gain (before tax and NICs) on the exercise of 851,889 options amounting to £1,712,000 and Mr Ward made a gain of £652,000 on the exercise of  
324,445 options. Richard Marsden was the highest paid director during the year ended 31 December 2019 and did not exercise any options during that year. 

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

(iii)  The Committee approved that executive directors could carry forward a maximum of 10 days’ holiday pay into 2021 and that, owing to the exceptional nature 

of 2020, the remaining element of unused holiday entitlement could be paid. The amounts payable in respect of Mr Marsden, Dr Monk and Mr Ward amounted 
to £8,000, £8,000 and £6,000 and were paid in Q1 2021. These sums are included under Benefits in the table above.

(iv)  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.

In respect of key management personnel (the three executive directors), for the year ended 31 December 2020, the total share-based 
payment amounted to £152,000 (2019: £85,000) and total social security costs were £134,000 (2019: £126,000).   

On behalf of the Board

Iain Buchanan 
Chairman of the Remuneration and Nomination Committee

11 May 2021

BDO, the Company’s auditors, were present at all meetings. 
John Ward, the Group’s Chief Financial Officer, 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 21, 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 £46,000. £9,000 
of these fees relate to tax compliance services. The majority of 
the remaining tax advice was for indirect tax advisory services in 
relation to the Group’s overseas manufacturing and clinical trial 
activities. Whilst the Committee notes that the non-audit fees are 
in excess of the audit fees, it has confirmed that the amount of the 
audit fees are not material to BDO or the audit partner concerned. 
The Committee therefore considers that the amount of non-audit 
fees does not impair the independence of BDO as auditor. 

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

11 May 2021

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 21. 

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 three times during the year ended 31 December 2020, 
with all members attending all meetings, and covered the 
following matters:

•  May 2020: 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.

•  September 2020: interim report completion meeting for 
2020, including agreement of scope and materiality and 
reviews of: the financial forecast to support the Group’s 
ability to account on a going concern basis; the report from 
the Company’s auditors; and the interim statement.

•  December 2020: planning meeting for the 2020 year-end 

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

The Committee also met in March 2021 for the audit completion 
meeting for the 2020 year-end audit including reviews of: the 
support for Synairgen plc’s investment in Synairgen Research 
Limited; the financial forecast to support the Group’s ability to 
account on a going concern basis, the auditor’s report on the audit; 
and the annual report.

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 accounting standards in conformity with the 
requirements of the Companies Act 2006 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  

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 

Simon Holden 
Company Secretary

11 May 2021

Research and development
During the year ended 31 December 2020, the Group 
has invested £15,495,000 (2019: £3,460,000) in 
research and development activities and a review of this 
expenditure is included in the Strategic Report.

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 Phase III clinical trial of SNG001 in 
COVID-19 patients and the manufacturing scale-up activities. 

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 16 to the financial statements on pages 49 and 50.

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

Substantial shareholdings
As at 11 May 2021, the Company had been advised of the 
following shareholders with an interest of 3% or more in its 
ordinary share capital:

in respect of the personal liabilities which may be incurred 
by directors and officers of the Group during the course 
of their service with the Group. This insurance has been 
in place during the year and to the date of this report.

Auditors
All of the current directors have taken all the steps that 
they ought to have taken to make themselves aware of any 
information needed by the Company’s auditors for the purposes 
of their audit and to establish that the auditors are aware of 
that information. The directors are not aware of any relevant 
audit information of which the auditors are unaware.

Independent Auditor’s Report 
to the members of Synairgen plc

Opinion on the financial statements 
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 2020 and of the Group’s loss for the year  
then ended;

•  the Group financial statements have been properly prepared 
in accordance with international accounting standards in 
conformity with the requirements of the Companies Act 2006;

•  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.

We have audited the financial statements of Synairgen plc (the 
‘Parent Company’) and its subsidiary (the ‘Group’) for the year 
ended 31 December 2020 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 accounting standards in conformity with 
the requirements of the Companies Act 2006. 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).

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 believe 
that the audit evidence we have obtained is sufficient 
and appropriate to provide a basis for our opinion. 

Independence

We remain 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.

Conclusions relating to going concern
In auditing the financial statements, we have concluded that 
the Directors’ use of the going concern basis of accounting 
in the preparation of the financial statements is appropriate. 
Our evaluation of the Directors’ assessment of the Group and 
the Parent Company’s ability to continue to adopt the going 
concern basis of accounting included evaluating the following: 

•  The Directors’ method for assessing going concern 

including the relevance and reliability of underlying data 
used to make the assessment, and whether assumptions 
and changes to assumptions from prior years are 
appropriate and where relevant consistent with each 
other. The assumptions were assessed against the Group’s 
development plans and committed expenditure.

•  The Directors’ plans for future actions in relation to 
the going concern assessment including whether 
such plans are feasible in the circumstances.

•  The Directors’ stress-testing of the forecasts to the extent 

of reasonable worst-case scenarios, solely in relation 
to their estimates of planned operational costs.

•  The adequacy and appropriateness of disclosures in the 

financial statements regarding the going concern assessment.

We carried out the above procedures through using our 
understanding of the business model, objectives, strategies 
and related business risk, the measurement and review of 
the entity’s financial performance, forecasting and budgeting 
processes and the entity’s risk assessment process.

Based on the work we have performed, we have not 
identified any material uncertainties relating to events 
or conditions that, individually or collectively, may cast 
significant doubt on the entity’s ability to continue as a 
going concern for a period of at least twelve months from 
when the financial statements are authorised for issue. 

Our responsibilities and the responsibilities of the Directors  
with respect to going concern are described in the relevant 
sections of this report.

Our Group audit was scoped by obtaining an understanding 
of the Group and its environment, including the Group’s 
system of internal control, and assessing the risks of material 
misstatement in the financial statements. We also addressed 
the risk of management override of internal controls, including 
assessing whether there was evidence of bias by the Directors 
that may have represented a risk of material misstatement.

The Group’s operations are based solely in Southampton,  
United Kingdom. 

Both components, Synairgen plc and Synairgen Research 
Limited, are considered significant components and were 
subject to full-scope audits by the group audit team.

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

Key audit matters

Key audit matters are those matters that, in our professional 
judgement, were of most significance in our audit of the financial 
statements of the current period and include the most significant 
assessed risks of material misstatement (whether or not due to 
fraud) that we identified, 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 matter

Clinical trial accounting

The accounting policy in 
respect of the accounting 
for manufacturing activities 
is included within the 
Inventories accounting policy 
on page 41; the accounting 
policy in respect of research 
and development activities is 
included within the “Research 
and development” accounting 
policy on page 40; significant 
balance sheet items in relation 
to clinical trial activities are 
included in notes 13 and 15.

Due to the nature of clinical trials, 
drug manufacturing processes 
and general research, it is often 
difficult to estimate the length of 
time a particular research process 
is going to take. This is reinforced 
by the fact that such activities are 
often contracted to third parties.

As a result, it can be challenging for 
the entity to measure what costs have 
been incurred in relation to outsourced 
research and manufacturing at a 
particular point in time and as such, 
based on billings received, whether 
project accruals and prepayments 
recorded are reasonably estimated. 

Our audit risk is focused on whether 
the relevant expenditure has been 
appropriately included in the income 
statement and whether prepayments 
and accruals are appropriately 
calculated and recognised.

How the scope of our audit  
addressed the key audit matter

We have assessed the key terms of all material ongoing third party 
research and drug manufacturing agreements to ensure that we 
understood the nature of the goods or services to be provided, the 
total contracted costs and, where relevant, milestone payments. 

We then reviewed a sample of invoices raised in 
accordance with the research and drug manufacturing 
agreements and reviewed their content to determine the 
correct accounting treatment and if the expenditure was 
appropriately classified within the financial statements.

 Where relevant, we have obtained third party confirmation 
of stages of completion of a project and compared the 
progress against both the contract and the value of 
expenditure billed to date. We have then verified this to 
the year-end cost position to determine whether related 
prepayments or accruals are accurately recognised. 

We verified the completeness of management’s calculation of 
the accruals and prepayments position by selecting a sample 
of significant purchase orders raised in the final quarter of the 
year and checking that, based on evidence such as invoices 
received and third party confirmations, the associated costs 
had been recognised in the appropriate accounting period.

We also considered completeness of related accruals through 
testing a sample of invoices recorded post year end checking 
that, based on the terms of the service, they had been accounted 
for correctly. In addition, we inspected board meeting minutes 
for evidence of any significant contracts entered that might 
require cost accruals that had not been recognised.

Key observations:

We consider the Group’s related accounting policies 
have been appropriately applied, in the recording 
of research and development expenditure, related 
prepayments and accruals in the financial statements.

Our application of 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 users that are 
reasonably 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.

Based on our professional judgement, we determined 
materiality for the financial statements as a whole 
and performance materiality as follows:

Component materiality

Aside from the Parent company, there is only one additional 
component – being the trading subsidiary Synairgen Research 
Limited. The materiality for this component was set at 
£800,000 (2019: £180,000), based on 90% (2019: 90%) of Group 
materiality. In the audit of this component, we further applied 
a performance materiality level of 75% of the component 
materiality to our testing to ensure that the risk of errors 
exceeding component materiality was appropriately mitigated.

Reporting threshold

We agreed with the Audit Committee that we would report to them all 
individual audit differences in excess of £18,000 (2019: £4,000). 
We also agreed to report differences below this threshold that, 
in our view, warranted reporting on qualitative grounds.

Other information
The directors are responsible for the other information. The other 
information comprises the information included in the Annual 
Report and Accounts 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. Our 
responsibility is to read the other information and, in doing so, 
consider whether the other information is materially inconsistent 
with the financial statements or our knowledge obtained in 
the course of the audit, or otherwise appears to be materially 
misstated. If we identify such material inconsistencies or 
apparent material misstatements, we are required to determine 
whether this gives rise to a material misstatement in the 
financial statements themselves. If, based on the work we have 
performed, we conclude that there is a material misstatement 
of this other information, we are required to report that fact.

We have nothing to report in this regard.

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

Other Companies Act 2006 reporting
Based on the responsibilities described below and our 
work performed during the course of the audit, we are 
required by the Companies Act 2006 and ISAs (UK) to report 
on certain opinions and matters as described below.

Strategic 
Report and  
Directors’ 
Report

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.

In the light of the knowledge and understanding 
of the Group and 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.

Matters on 
which we 
are required 
to report by 
exception

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 statement, the Directors are responsible for 
the preparation of the financial statements and for being 
satisfied that they give a true and fair view, and for such 
internal control as the Directors determine is necessary to 
enable the preparation of financial statements that are free 
from material misstatement, whether due to fraud or error.

In preparing the financial statements, the Directors are 
responsible for assessing the 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.

Extent to which the audit was capable of 
detecting irregularities, including fraud

Irregularities, including fraud, are instances of non-
compliance with laws and regulations. We design procedures 
in line with our responsibilities, outlined above, to detect 
material misstatements in respect of irregularities, including 
fraud. The extent to which our procedures are capable of 
detecting irregularities, including fraud, is detailed below.

We focused on laws and regulations that could give 
rise to a material misstatement in the Group financial 
statements and the susceptibility of the entity’s financial 
statements to material misstatement including fraud. 
Our procedures included, but were not limited to:

• Evaluation of management incentives and opportunities 

for fraudulent manipulation of the financial 
statements including management override;

• This evaluation involved a particular focus on the judgements 
and estimates inherent in the key audit matter and exercising 
professional scepticism in considering the impact of those 
estimates and judgements on the reported results and 
key performance measures such as the loss before tax;

• The evaluation also involved gaining an understanding of 
management remuneration schemes and the extent to 
which remuneration is influenced by reported results;

• Discussions with Management and the Audit 

Committee regarding known or suspected instances 
of non-compliance with laws and regulations;

• Obtaining and understanding of controls designed 

to prevent and detect irregularities;

• Review of board meeting minutes for any evidence of 
fraud or non-compliance with laws and regulations 
including health and safety; taxation regulations; and 
drug development regulatory authorities and

• Assessment of journal entries to accounts that 
are considered to carry a greater risk of fraud 
as part of our planned audit approach.

We also communicated relevant identified laws and regulations 
and potential fraud risks to all engagement team members 
and remained alert to any indications of fraud or non-
compliance with laws and regulations throughout the audit.

Our audit procedures were designed to respond to risks of 
material misstatement in the financial statements, recognising 
that the risk of not detecting a material misstatement due 
to fraud is higher than the risk of not detecting one resulting 
from error, as fraud may involve deliberate concealment by, for 
example, forgery, misrepresentations or through collusion. There 
are inherent limitations in the audit procedures performed and 
the further removed non-compliance with laws and regulations 
is from the events and transactions reflected in the financial 
statements, the less likely we are to become aware of it.

A further description of our responsibilities is 
available on the Financial Reporting Council’s website 
at: 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.

Amendments to Existing Standards  
With effect from 1 January 2020, the Group adopted two amendments to existing standards: 

(i)  Amendments to References to the Conceptual Framework in IFRS Standards 
The revised Conceptual Framework introduces a number of new aspects including: concepts on measurement, including factors to be 
considered when selecting a measurement basis; concepts on presentation and disclosure, including when to classify income and expenses in 
other comprehensive income; and guidance on when assets and liabilities are removed from financial statements. It also updates the definitions 
of asset and liability and the criteria for recognising assets and liabilities in financial statements. Finally, it has clarified the guidance on prudence, 
stewardship, measurement uncertainty, and substance over form.

(ii)  Amendments to IAS 1 and IAS 8 – Definition of Material 
The amendments clarify the definition of ‘material’ and align the definition used in the Conceptual Framework and the standards themselves.

The adoption of these amendments has not had a material impact on the Group’s financial statements.

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 Phase III clinical trial of SNG001 in COVID-19 patients and the manufacturing scale up activities. 

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 57) 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. No substantive performance obligations on the Group remained at 1 January 2019. 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.

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.

Notes to the Consolidated Financial Statements 

Notes to the Consolidated Financial Statements 

for the year ended 31 December 2020 (continued)

for the year ended 31 December 2020 (continued)

1. Accounting policies (continued) 

Financial liabilities

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.

Where vested share options are exercised by the participants but settled by the Company net of shares withheld to meet the participant’s tax and 
NIC liabilities (‘net settlement’), the payment to meet such tax and NIC liabilities is treated as a deduction to equity to the extent that the payment 
equates to the settlement date fair value of the shares withheld, and in the consolidated statement of cash flows is included within cash flows from 
financing activities.  

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 of products approved for sale are stated at the lower of cost and net realisable value. 

Raw materials inventory purchased and associated processing/manufacturing costs, related to therapeutics produced for clinical trial purposes or 
commercial use ahead of regulatory approval, are expensed as incurred through research and development expenditure.

Where inventory manufacturers invoice in advance of the manufacturing activities, the invoice is recorded as a prepayment within trade and  
other receivables.

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 (e.g. 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.

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.

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.

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.

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.

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:

• 

• 

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 nor 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.

The directors consider that the research and development tax credit recognised in respect of 2020, which amounts to £3.8 million  
(2019: £0.9 million), is a critical accounting estimate on account of its size.

The expected reduction in main UK corporation tax rate to 17% from 1 April 2020 enacted by the Finance Act 2016 was reversed in the Finance 
Act 2020. Therefore, the UK statutory tax rate remains at 19% and the rate used to calculate any deferred tax balances at 31 December 2020 has 
increased from 17% to 19%. 

For the purpose of presentation in the consolidated statement of comprehensive income, remuneration costs of £1,116,000 (2019: £788,000) are 
included in research and development expenditure and £1,095,000 (2019: £879,000) are included in other administrative expenses.

At 31 December 2020 the Group has trading losses carried forward which are available for offset against future profits of the Group amounting to 
£24,254,000 (2019: £16,653,000) and non-trading losses of £2,847,000 (2019: £2,444,000). At 31 December 2020 the Group has an unrecognised 
deferred tax asset in respect of these losses of £5,149,000 (2019: £3,247,000). 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 £8,921,000 (2019: £248,000)  
and a deferred tax asset of £1,695,000 (2019: £42,000) 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.

The movement on the unrecognised deferred tax asset comprises the following:

Unrecognised deferred tax asset at the start of the year

Change in tax rate

Movement in the year

Unrecognised deferred tax asset at the year-end

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.

The Group has one lease with its landlord, the University of Southampton, which provides the Group with office space and  
access to laboratory equipment. A new two-year lease was entered into with effect from 1 August 2019. 

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.

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 and National Westminster Bank Plc, which 
at 31 December 2020 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 2020 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 the three above institutions.

Currency risk
During the year under review, the Group was exposed to Euro and US Dollar currency movement as some of the manufacturing costs and 
clinical trial costs are denominated in these currencies. To naturally hedge against currency movement, the Group purchases these currencies 
in advance of payment due dates.

Capital structure and funding

The Group is funded by equity capital, reflecting the early-stage nature of its discovery and development programmes.

The Group considers its capital to be its total equity, which at 31 December 2020 amounted to £85.14 million (2019: £2.25 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.

Cash and cash equivalents held by the Group at 31 December 2020 amounted to £74.98 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:

(i)  Trade and other receivables shown above excludes prepayments and other taxes, which are not a contractual right to receive cash,  

amounting to £9,371,000 (2019: £95,000).

(ii)  Trade and other payables shown above excludes amounts due in respect of social security and other taxes, which are not a contractual obligation to pay cash, 

amounting to £224,000 (2019: £114,000).

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.

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 £46,000 (2019: £9,000).   

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 2020 
and 31 December 2019 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.

The Group did not have any bank borrowings as at 31 December 2020 (2019: £nil).

There have been ten significant issues of shares raising a total (net of costs) of £127.61 million, with the most recent two raising £97.89 million  
in March and October 2020. The other major sources of funding received by the Group from the formation of the business until 31 December 2020 
have been: revenues from licensing transactions of £9.25 million, research and development tax credits of £5.49 million, bank interest of £1.81 million, 
and revenues from collaborative work of £0.79 million.

Notes to the Parent Company Financial Statements 

Notes to the Parent Company Financial Statements 

for the year ended 31 December 2020

for the year ended 31 December 2020 (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 Limited, to which the Company has confirmed its intention to provide financial support for a 
period of not less than twelve months from the date that its financial statements for the year ended 31 December 2020 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 Phase III clinical trial 
of SNG001 in COVID-19 patients and the manufacturing scale up activities being conducted by Synairgen Research Limited. 

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

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. 

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 £51.1 million (2019: £26.9 million). 

At 31 December 2020, the Directors assessed recoverable amount by reference to Synairgen Research Limited’s fair value less costs to sell,  
estimated by reference to the AIM market capitalisation of the Group (since all group intellectual property is owned by the subsidiary)  
at that date, £306 million. No impairment was identified.

3. Profit and loss account

The only employees of the Company during 2020 and 2019 were the three executive directors. Their aggregate remuneration,  
which is borne by the Company’s subsidiary undertaking, comprised:

Wages and salaries
