VRP Invesco Variable Rate Preferred ETF

Verona Pharma plc (AIM: VRP) (Nasdaq: VRNA) (“Verona Pharma” or the “Company”), a clinical-stage biopharmaceutical company focused on developing and commercializing innovative therapies for respiratory diseases, announces financial results for the three and nine months ended September 30, 2020 and provides a corporate update.

"We continue to make outstanding progress and are delighted to have started four clinical trials in the third quarter including our pivotal ENHANCE-1 and 2 (Ensifentrine as a Novel inHAled Nebulized COPD thErapy) Phase 3 studies," said David Zaccardelli, Pharm. D., President and Chief Executive Officer. "This important milestone brings us closer to potentially submitting a New Drug Application in the U.S. for ensifentrine and addressing the urgent need for a novel therapy for the treatment of chronic obstructive pulmonary disease ("COPD").

"In addition to the two ENHANCE clinical trials which have both enrolled patients, we started a pilot clinical study to investigate ensifentrine delivered via pressurized metered-dose inhaler ("pMDI") formulation in U.S. patients hospitalized with COVID-19. Clinical data from prior studies of ensifentrine have demonstrated that it improves lung function and reduces cellular markers of inflammation in the lungs. We believe ensifentrine, with its novel mechanism of action, has the potential to benefit patients suffering from COVID-19. Results are anticipated in the first half of 2021.

"Also during the third quarter, we initiated the second, multiple dose part of a Phase 2 study with the pMDI formulation of ensifentrine in COPD, which was postponed due to the pandemic. Results are expected in the first half of 2021.

"This clinical progress is supported by the $200 million raise we completed in July and we appreciate the highly experienced life science investors that participated in the offering. The funds are expected to support our operations and Phase 3 clinical programs into 2023."

OUTLOOK AND STRATEGY

Verona Pharma aims to improve health and quality of life for the millions of people affected by respiratory diseases. The Company's first-in-class development candidate, ensifentrine, has the potential to provide benefit to patients suffering from respiratory conditions such as COPD, COVID-19, cystic fibrosis ("CF") and asthma.

Ensifentrine is a novel, investigational inhaled therapy that has been shown to act as both a bronchodilator and an anti-inflammatory agent in one compound. Initially, the Company is advancing the development of nebulized ensifentrine for the maintenance treatment of COPD.

We are pleased to announce that Verona Pharma has met the following 2020 objectives that were established at the time of the management change:

• Completing an End-of-Phase 2 meeting with the FDA in May to receive guidance on the design of the Phase 3 program with nebulized ensifentrine.
• Securing $200 million in gross proceeds ($185.5 million net of commissions and expenses) through a private placement in July which we expect to be sufficient capital to fund the Phase 3 program for nebulized ensifentrine.
• Initiating the ENHANCE Phase 3 program with nebulized ensifentrine in moderate to severe COPD patients in September.

OPERATIONAL AND DEVELOPMENT HIGHLIGHTS FOR THE THREE MONTH PERIOD ENDED SEPTEMBER 30, 2020

Financial

• In July, the Company completed a $200 million private placement of American Depositary Shares ("ADSs") and ordinary shares that resulted in net proceeds of approximately $185.5 million after giving effect to transaction related fees and expenses (the "Private Placement"). The Company expects the proceeds of the Private Placement to be sufficient to support its operations and clinical programs into 2023.
• In September, Verona Pharma announced plans to delist from the AIM stock market effective from 7:00 am GMT on October 30, 2020. The Company will retain its listing on the Nasdaq Global Market ("Nasdaq"). The move is expected to further enhance liquidity of trading by combining all trading transactions on Nasdaq and to reduce costs through removing duplicative listing and compliance fees.
• Also in September, Verona Pharma rang the Nasdaq closing bell in celebration of the Company's $200 million financing.
• In the third quarter the Company changed its accounting policy with regards to its presentational currency and is now presenting financial results in US dollars. Historical results, including the six months ended June 30, 2020, have been retrospectively presented in US dollars.

Clinical

• In July, the Company received a notice to proceed from the FDA for our Investigational New Drug Application to evaluate pMDI ensifentrine in a randomized, double-blind, placebo-controlled pilot clinical study for the treatment of patients hospitalized with COVID-19 and, in September, the Company initiated the study. The study will evaluate the effect of ensifentrine on key outcomes in patients hospitalized with COVID-19 including facilitation of recovery from the viral infection, clinical status improvement and reduction in supplemental oxygen use and progression to mechanical ventilation.
• In August, the Company initiated the second, multiple dose, part of a Phase 2 study to evaluate pMDI ensifentrine in patients with moderate to severe COPD. Results are expected in the first half of 2021.
• In September, the Company initiated its ENHANCE Phase 3 trials to evaluate the efficacy and safety of nebulized ensifentrine in patients with moderate to severe COPD. The two randomized, double-blind, placebo-controlled studies (ENHANCE-1 and ENHANCE-2) will evaluate ensifentrine as monotherapy and added onto a single bronchodilator. Each study will enroll approximately 800 moderate to severe, symptomatic COPD patients at sites primarily in the U.S. and Europe. The two study designs will replicate measurements of efficacy and safety data over 24 weeks, but ENHANCE-1 will also evaluate longer-term safety in 400 patients over 48 weeks.
• Additionally in September, a detailed analysis of symptom data from a previously reported Phase 2b clinical trial with nebulized ensifentrine as a maintenance treatment for COPD was published in the leading peer reviewed journal for specialists and healthcare professionals, International Journal of Chronic Obstructive Pulmonary Disease. The analyses demonstrate that ensifentrine meaningfully improved symptoms and quality of life after 4 weeks in patients with moderate to severe COPD.
• Also in September, Dr. Tara Rheault, Vice President, R&D and Global Project Management, presented new subgroup analysis from Phase 2b trials with nebulized ensifentrine in COPD at the European Respiratory Society International Congress. The data demonstrated that ensifentrine as monotherapy or added onto tiotropium (Spiriva® Respimat®) improved lung function in moderate or severe COPD patients regardless of smoking status or history of chronic bronchitis over 4 weeks.

FINANCIAL HIGHLIGHTS

• Net cash, cash equivalents and short term investments at September 30, 2020, amounted to $202.0 million (December 31, 2019: $40.8 million). The increase is due to the completion of the Private Placement with gross proceeds of approximately $200 million. The net proceeds of the Private Placement were approximately $185.5 million after deducting placement agent fees and other expenses. We continue to evaluate and consider other financing vehicles, including venture debt and other facilities, to potentially provide us with further financial flexibility.
• For the nine months ended September 30, 2020, the Company reported operating loss of $46.2 million (nine months ended September 30, 2019: $42.7 million) and reported loss after tax of $41.4 million (nine months ended September 30, 2019: $31.0 million). Research and development costs fell by $7.1 million in the nine months ended September 30, 2020, compared to the prior period, primarily due to significantly higher costs of an ongoing Phase 2b study in 2019 compared to the start up costs incurred in 2020 for the ENHANCE program. General and administrative costs increased by $10.6 million as the 2020 period had higher costs related to share based payment charges, executive changes and certain costs related to the Private Placement recorded as expenses in the Statement of Comprehensive Income.
• The Company reported loss per share of 21.0 cents for the nine months ended September 30, 2020 (nine months ended September 30, 2019: 29.4 cents).
• Net cash used in operating activities for the nine months ended September 30, 2020 was $25.7 million (nine months ended September 30, 2019: $31.3 million). Cash used was lower predominantly due to lower cash based operating costs and a higher cash tax credit received.
• Cash generated from financing activities of $188 million was primarily related to net cash proceeds from the Private Placement.
• In the nine months ended September 30, 2020 the Company re-evaluated its assumed contingent liability and In-Process Research and Development asset in light of its determination that ensifentrine had moved from Phase 2 to Phase 3 stage of clinical development. Future cashflows relating to a potential milestone payment and potential royalties payable were remeasured applying updated estimates of probabilities of success based on the assumed reduced clinical risk of moving into Phase 3. Accordingly the Company recorded an increase of $27.7 million to the assumed contingent liability and a corresponding increase to the related In-Process Research and Development intangible asset. There is no material effect on current period comprehensive loss, net assets or cashflows.

COVID-19 IMPACT AND BUSINESS CONTINUITY

To help protect the health and safety of the patients, caregivers and healthcare professionals involved in its ongoing clinical trials of ensifentrine, as well as its employees and independent contractors, the Company continues to follow guidance from the FDA and other health regulatory authorities regarding the conduct of clinical trials during the COVID-19 pandemic to ensure the safety of study participants, minimize risks to study integrity, and maintain compliance with good clinical practice (GCP). The Company continues to review this guidance and the effect of the COVID-19 pandemic on its operations and clinical trials and will provide an update if it becomes aware of any meaningful disruption caused by the pandemic to its clinical trials.

Verona Pharma is closely monitoring activities at the Company’s contract manufacturers associated with clinical supply for the ongoing clinical trials, and is satisfied that appropriate plans and procedures are in place to ensure uninterrupted future supply of ensifentrine to the clinical trial sites, subject to potential limitations on their operations and on the supply chain due to the COVID-19 pandemic. The Company is continuing to monitor this situation and will provide an update if it becomes aware of any meaningful disruption caused by the pandemic to the clinical supply of ensifentrine for its clinical trials.

Corporate Operations and Financial Impact

Verona Pharma has also implemented measures to help keep the Company’s employees, families, and local communities healthy and safe. All employees are working remotely and all business travel has been restricted.

The COVID-19 pandemic has caused significant disruption to the financial markets but Verona Pharma has successfully raised sufficient capital to fund the Phase 3 program for nebulized ensifentrine.

COVID-19 Risk Factor

Verona Pharma has assessed the potential impact on its business of the COVID-19 pandemic and updated its risk factor disclosures on a Report on Form 6-K filed with the SEC on April 30, 2020.

OPERATIONAL REVIEW

Company Overview

Verona Pharma is focused on developing and commercializing our first-in-class Phase 3 candidate, ensifentrine, for the treatment of significant unmet respiratory needs such as chronic obstructive pulmonary disease (“COPD”). Ensifentrine has a novel mechanism of action and has the potential to be the first therapy for the treatment of respiratory diseases that combines bronchodilator and anti-inflammatory activities in one compound. As well as COPD, ensifentrine has potential applications in COVID-19, cystic fibrosis, asthma and other respiratory diseases.

Verona Pharma is evaluating nebulized ensifentrine in the Phase 3 clinical program ENHANCE (Ensifentrine as a Novel inHAled Nebulized COPD thErapy) for the maintenance treatment of COPD. The Company raised gross proceeds of $200 million through a private placement in July 2020 and expects the funds to support its operations and Phase 3 clinical program into 2023. Two additional formulations of ensifentrine are currently in Phase 2 development for the treatment of COPD: dry powder inhaler ("DPI") and pressurized metered-dose inhaler ("pMDI"). Ensifentrine is being evaluated in a pilot clinical study in U.S. patients hospitalized with COVID-19.

Ensifentrine has demonstrated significant and clinically meaningful improvements in both lung function and COPD symptoms, including breathlessness, in patients with moderate to severe COPD. In addition, ensifentrine showed further improved lung function and reduced lung volumes in patients taking standard short- and long-acting bronchodilator therapy, including maximum bronchodilator treatment with dual/triple therapy. Ensifentrine has been well tolerated in clinical trials involving more than 1,300 people to date.

Ensifentrine highlights:

• First-in-class dual bronchodilator and anti-inflammatory agent in a single molecule
• Potentially the first novel class of bronchodilator in COPD in over 40 years
• Potentially the only bronchodilator option as an add-on to existing dual / triple therapy

COPD is a common, progressive, and life-threatening respiratory disease without a cure. It damages the airways and lungs, leading to debilitating breathlessness, hospitalizations and death. COPD has a major impact on everyday life. Patients struggle with basic activities such as getting out of bed, showering and walking. COPD affects approximately 384 million people worldwide. It is the third leading cause of death globally, according to the World Health Organization.

COPD patients are frequently treated with bronchodilators, to relieve airway constriction and make it easier to breathe, and with corticosteroids, to reduce lung inflammation. Despite receiving maximum therapy, many patients, more than 1.2 million in the U.S. alone, remain symptomatic and urgently need additional treatment. We believe that ensifentrine can provide significant benefits for these patients.

The pharmacological profile of ensifentrine including its novel mechanism of action, which is complementary to existing classes, strong improvement in COPD symptoms and meaningful improvement in quality of life, addresses the large unmet need experienced by COPD patients today.

Ensifentrine is a dual phosphodiesterase (“PDE”) 3 and PDE4 inhibitor. It is delivered via inhalation, locally to the lung to maximize pulmonary exposure to ensifentrine while minimizing systemic exposure. This minimizes side-effects such as the gastrointestinal disturbance associated with oral PDE4 inhibitors and the cardiovascular side-effects seen with oral PDE3 inhibitors.

The nebulized formulation of ensifentrine can be used by adults of any age and dexterity and regardless of peak inspiratory flow, offering advantages to patients who may struggle to operate handheld inhaler devices or have low peak inspiratory flow. Nevertheless, handheld inhaler formats are also important delivery mechanisms in the approximately $9.6 billion U.S. market for maintenance COPD therapies. Verona Pharma has developed formulations of ensifentrine in DPI and pMDI formats and successfully demonstrated proof of concept in COPD patients with these formulations. The development of pMDI and DPI formulations of ensifentrine provides expanded opportunities in life cycle management including new indications, formulation combinations and collaborations.

Verona Pharma sees its initial market opportunity as the U.S. and the Company intends to commercialize nebulized ensifentrine itself in this market. Outside of the U.S., Verona Pharma intends to identify collaborators that can maximize ensifentrine's potential in those regions.

FINANCIAL REVIEW

Financial review of the nine and three month periods ended September 30, 2020

Nine months ended September 30, 2020

Research and Development Costs

Research and development costs were $28.1 million for the nine months ended September 30, 2020, compared to $35.2 million for the nine months ended September 30, 2019, a decrease of $7.1 million, predominantly attributable to a $9.9 million decrease in clinical trial expenses, partially offset by a $2.5 million increase in non-cash share based payment charges. While there were six clinical trials (ongoing, in preparation or closing down) in the nine months ended September 30, 2020 compared to four in the same period in 2019, the costs related to the Phase 2b four-week clinical study with ensifentrine added on to tiotropium in the 2019 period were significantly higher than the start-up costs of the ENHANCE program that were incurred in the 2020 period.

General and Administrative Costs

General and administrative costs were $18.1 million for the nine months ended September 30, 2020, compared to $7.5 million for the nine months ended September 30, 2019, an increase of $10.6 million. The increase included $2.7 million of costs relating to executive changes and relocation of our U.S. office to North Carolina, $1.7 million in higher Director's and Officers liability insurance costs, $1.6 million in costs relating to the Private Placement and a $4.4 million increase in non-cash share based payment charges. Other costs increased by $0.2 million.

Finance Income and Expense

Finance income and expense are driven by the changes in the fair value of the warrant liability, changes in the present value of the assumed contingent liability, foreign exchange movements on cash and cash equivalents and interest income and expense.

Finance income was $1.3 million for the nine months ended September 30, 2020, and $4.2 million for the nine months ended September 30, 2019. Finance income was lower in the nine months ended September 30, 2020 as the fair value of the warrant liability decreased by $2.7 million in the 2019 period, compared to an increase in the nine months ended September 30, 2020. The increase in the 2020 period was recorded in finance expense.

Gains on cash and short term investments due to foreign exchange movements were $1.2 million in the nine months ended September 30, 2020, compared to $0.7 million in the same period in the prior year.

Interest received on cash and short term investments reduced by $0.7 million due to lower overall interest rates and a change in our investment policy to use government debt money market funds compared to term deposits previously utilized.

Finance expense was $2.2 million for the nine months ended September 30, 2020, compared to $0.1 million for the nine months ended September 30, 2019. The increase in the nine months ended September 30, 2020 was primarily related to a $1.4 million accounting charge relating to the unwind of the discount on the assumed contingent liability as the present value of the contingent liability increases as the estimated time to potential payment is becoming closer. Additionally, there was a $0.7 million charge relating to an increase in the fair value of the warrant liability in the nine months ended September 30, 2020. In the prior period the present value of the warrant liability decreased resulting in finance income.

Taxation

The tax credit in the Statement of Comprehensive Income is predominantly made up of the UK tax credit and a small tax charge relating to our US operations. The UK tax credits are calculated as a percentage of qualifying research and development expenditure and are payable in cash by the UK government to the Company. Credits recorded in the 2020 financial year are expected to be received in the 2021 financial year. We expect the magnitude of these credits to increase as expenditures on our Phase 3 program accelerate and they continue to be a significant element in our financing strategy.

The tax credit for the nine month period ended September 30, 2020 was $5.7 million compared to a credit of $7.6 million for the nine months ended September 30, 2019, a decrease of $1.9 million. The decrease in the credit amount was attributable to our decreased expenditures on research and development in 2020, compared to the same period in 2019.

Assumed contingent liability and In-Process Research and Development Asset

In the second quarter of 2020, the Company re-evaluated its contingent liability and In-Process Research and Development asset in light of its determination that ensifentrine has moved from Phase 2 to Phase 3 stage of clinical development. Future cashflows relating to a milestone payment and potential royalties payable were remeasured. After applying estimated probabilities of success, the assumed contingent liability that relates to these potential future cashflows was adjusted. Accordingly the Company recorded an increase of $27.7 million to the contingent liability and a corresponding increase to the related In-Process Research and Development asset. There is no material effect on current period comprehensive loss, net assets or cashflows.

The discount that is used to calculate the present value of the assumed contingent liability unwinds each quarter as the time to potential payment becomes closer and is recorded as a finance expense.

Private Placement

On July 17, 2020, Verona Pharma announced that it had raised approximately $200 million in a private placement with new and existing institutional and accredited investors. The Private Placement comprised a placement of 39,090,009 ADSs, each representing eight Ordinary Shares or non-voting Ordinary Shares of the Company, at a price of $4.50 per ADS, and 43,111,112 of the Company’s Ordinary Shares at the equivalent price per Ordinary Share of $0.5625.

The net proceeds of the Private Placement were approximately $185.5 million after deducting placement agent fees and associated expenses (including costs recorded to both equity and the Statement of Comprehensive Income). $1 million of such costs were paid in October 2020. Should the Company need to raise additional capital in the future, there can be no assurance that we will be able to do so on acceptable terms or at all.

Cash Flows

Net cash used in operating activities decreased to $25.7 million for the nine months ended September 30, 2020, from $31.3 million for the nine months ended September 30, 2019, a fall of $5.6 million. Operating loss in the nine months ended September 30, 2020 was $3.5 million higher which included $6.9 million higher non-cash share based payment charges, so cash related charges were approximately $3.4 million lower. In addition, the cash tax credit of $9.0 million received was $3.8 million higher than in the nine months ended September 30, 2019. Offsetting this, the timing of supplier payments led to $1.6 million higher cash outflow in the current period.

The decrease in net cash generated in investing activities to $9.7 million for the nine months ended September 30, 2020, from $49.0 million for the nine months ended September 30, 2019 was due to the net movement of funds from short term investments to cash being less in the 2020 period.

The $187.5 million increase in cash generated from financing activities was primarily due to net cash received from the Private Placement.

Cash, cash equivalents and short-term investments

Net cash, cash equivalents and short-term investments at September 30, 2020, increased to $202.0 million from $40.8 million at December 31, 2019 due to net receipts from the Private Placement, partially offset by utilization of cash in ordinary operating activities.

Net assets

Net assets increased to $197.7 million at September 30, 2020, from $44.9 million at December 31, 2019. This was predominantly due to the increase in equity from the Private Placement, partially offset by Company's operating activities.

Three months ended September 30, 2020

The operating loss for the three months ended September 30, 2020, was $21.2 million (September 30, 2019: $17.2 million) and the loss after tax for the three months ended September 30, 2020, was $19.9 million (September 30, 2019: $12.5 million).

Research and Development Costs

Research and development costs were $12.7 million for the three months ended September 30, 2020, compared to $14.7 million for the three months ended September 30, 2019, a decrease of $2.0 million.

This decrease was primarily attributable to a $4.2 million decrease in clinical trial expenses partially offset by a $2.4 million increase in the share based payment charge recorded in the three months ended September 30, 2020. There were costs relating to four clinical trials (ongoing, in preparation or closing down) in the three months ended September 30, 2020, compared to two in the comparative period, however, the costs related to the Phase 2b four-week clinical study with ensifentrine added on to tiotropium in the 2019 period, were significantly higher than the start-up costs of the ENHANCE program that were incurred in the 2020 period.

General and Administrative Costs

General and administrative costs were $8.5 million for the three months ended September 30, 2020, compared to $2.4 million for the three months ended September 30, 2019, an increase of $6.1 million. The increase was attributable to $1.6 million of costs related to the Private Placement which were recorded as expenses, a $1.0 million increase in Directors and Officers liability insurance costs and a $3.4 million increase in non-cash share based payment charges.

Finance Income and Expense

Finance income was $0.9 million for the three months ended September 30, 2020, and $1.5 million for the three months ended September 30, 2019. Finance income in the three months ended September 30, 2020, predominantly comprised a $0.8 million foreign exchange gain on cash and cash equivalents, which was broadly similar to the gain in the prior period. Also, the prior period included $0.4 million relating to movements in the fair value of the warrants (recorded in finance expense in the 2020 period) and $0.2 million of interest on cash balances.

Finance expense was $1.9 million for the three months ended September 30, 2020, compared to $54 thousand for the three months ended September 30, 2019. The increase was primarily due to a $1.0 million charge relating to the revaluation of the warrants and a $0.9 million charge relating to the unwind of the discount on the assumed contingent liability in the 2020 period.

Taxation

Taxation for the three months ended September 30, 2020, amounted to a credit of $2.3 million compared to a credit of $3.2 million for the three months ended September 30, 2019.

VERONA PHARMA PLC

NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

FOR THE NINE MONTHS ENDED SEPTEMBER 30, 2020

1. General information

Verona Pharma plc (the "Company") and its subsidiaries are a clinical-stage biopharmaceutical company focused on developing and commercializing innovative therapeutics for the treatment of respiratory diseases with significant unmet medical needs.

The Company is a public limited company, which is currently dual listed, with its ordinary shares listed on the AIM market operated by the London Stock Exchange and its American Depositary Shares ("ADSs") on the Nasdaq Global Market ("Nasdaq"). The Company is incorporated and domiciled in the United Kingdom.

The address of the registered office is 1 Central Square, Cardiff, CF10 1FS, United Kingdom.

The Company has two subsidiaries, Verona Pharma, Inc. and Rhinopharma Limited ("Rhinopharma"), both of which are wholly owned.

In September, 2020, Verona Pharma announced plans to delist from the AIM stock market effective as of October 30, 2020. The Company will retain its listing on the Nasdaq.

2. Basis of accounting

The unaudited condensed consolidated interim financial statements of Verona Pharma plc and its subsidiaries, Verona Pharma, Inc., and Rhinopharma Limited (together the "Group”), for the nine months ended September 30, 2020, do not include all the statements required for full annual financial statements and should be read in conjunction with the consolidated financial statements of the Group as of December 31, 2019.

The 2019 Accounts, on which the Company’s auditors delivered an unqualified audit report, have been delivered to the Registrar of Companies.

In the period the Company's functional currency changed from pounds sterling to US dollars and as a consequence the Group changed its accounting policy to present its financial statements in US dollars (see note 3). There have been no other changes to the accounting policies as contained in the annual consolidated financial statements as of and for the year ended December 31, 2019, which have been prepared in accordance with international financial reporting standards (“IFRS”) as issued by the International Accounting Standards Board and as adopted in the EU.

These unaudited condensed interim financial statements were authorized for issue by the Company’s board of directors on October 29, 2020.

The Group’s activities and results are not exposed to any seasonality. The Group operates as a single operating and reportable segment.

Going concern

The Group has incurred recurring losses since inception, including net losses of $40.5 million, $27.2 million and $26.8 million for the years ended December 31, 2019, 2018 and 2017, respectively. In addition, as of September 30, 2020, the Group had an accumulated loss of $180.0 million. The Group expects to continue to generate operating losses for the foreseeable future. On July 17, 2020, the Group announced it raised $200 million in a private placement (the "Private Placement"), with net proceeds after transaction related fees and expenses of approximately $185.5 million (see note 18).

As of the issuance date of these condensed consolidated interim financial statements, the Group therefore expects that its cash and cash equivalents will be sufficient to fund its operating expenses and capital expenditure requirements for at least twelve months from the issuance date of these condensed consolidated interim financial statements. Accordingly, the consolidated financial statements have been prepared on a basis that assumes the Group will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business.

Impairment of intangible assets, goodwill and non-financial assets

The Group continues to review the effect of the COVID-19 pandemic on its operations, ongoing and planned clinical trials and the potential disruption to financial markets. Management has determined that the current effect on the Group does not require an impairment of intangible assets or goodwill as the Company's market value still supports the value of the assets. However, management will continue to monitor the situation for any triggering events that relate to the pandemic or other issues.

Dividend

The Directors do not recommend the payment of a dividend for the nine months ended September 30, 2020, (nine months ended September 30, 2019: $nil and the year ended December 31, 2019: $nil).

3. Change in presentational and functional currency

Accounting policy change - change in presentational currency

On July 1, 2020, the Group changed its presentational currency from pounds sterling to US dollars. This change has been made retrospectively and comparative financial statements, including the six months to June 30, 2020, have been restated using the following procedures:

• assets and liabilities were translated into US dollars at the closing rate of exchange;
• income and expenses were translated into US dollars at the average rate for the month in which they were recorded, which approximates to the rate at the date of the transactions;
• equity balances were translated at historical rates at the date of transactions;
• translation differences were taken to the cumulative translation adjustment reserve; and
• statements of cash flows were prepared in the functional currency of the entities and translated into the presentational currency at rates approximating the dates of transactions.

In accordance with IAS 1, Presentation of Financial Statements, a transition balance sheet has been included in the primary financial statements.

Change in functional currency

The functional currency of an entity is defined by IAS 21, The Effects of Changes in Foreign Exchange Rates, as the currency of the primary economic environment in which an entity operates. Determining the point at which the functional currency changes is a matter of judgment as economic activity changes over time.

In the six months to June 30, 2020, management changes resulted in lower people costs being paid in pounds sterling. Following the Private Placement the Company entered into contracts to commence Phase 3 trials for ensifentrine and the majority of the costs are incurred in US dollars. Management has reviewed budgeted activities over the next five years and identified that the majority of costs from the second half of 2020 onwards will be incurred in US dollars. Furthermore, the Private Placement in July, 2020, raised funds in US dollars and after delisting from AIM any future fund raises will be in US dollars. Also, the commercial focus of Company is the US market.

As a consequence, management determined that the Company's functional currency has changed from sterling to US dollars and this has been accounted for prospectively from July 1, 2020. To convert the Company's books and records into US dollars assets and liabilities were translated at the closing rate of exchange as of June 30, 2020.

4. Segmental reporting

The Group’s activities are covered by one operating and reporting segment: Drug Development. There have been no changes to management’s assessment of the operating and reporting segment of the Group during the period.

All non-current assets are based in the United Kingdom apart from a right-of-use asset relating to a property lease, and associated fixtures and fittings, in the United States.

5. Financial instruments

The Group’s activities expose it to a variety of financial risks: market risk (including foreign currency risk), cash flow and fair value interest rate risk, credit risk and liquidity risk. The condensed consolidated interim financial statements do not include all financial risk management information and disclosures required in the annual financial statements, and they should be read in conjunction with the Group’s annual financial statements for the year ended December 31, 2019. In addition, due to the change of the Company's functional currency to US dollars and Private Placement, the foreign exchange risk profile of the Group has changed, discussed below.

Currency risk

Foreign currency risk reflects the risk that the Company's net assets will be negatively impacted due to fluctuations in exchange rates. The Company has not entered into foreign exchange contracts to hedge against gains or losses from foreign exchange fluctuations. Up to June 30, 2020, movements in the value of its US dollar balances impacted its net assets. From July 1, 2020, movements in the value of its pounds sterling balances impact its net assets.

The summary data about the Company's exposure to currency risk is as follows. Figures are the US dollar values of balances in each currency:

		September 30, 2020
		USD				GBP				EUR
		$'000s				$'000s				$'000s
Cash and cash equivalents		185,608				16,078				282
Trade, other payables and sterling element of assumed contingent liability		10,714				8,716				742

Sensitivity Analysis

A reasonably possible strengthening or weakening of the Euro or pounds sterling against US dollars as of September 30, 2020 would have affected the measurement of the financial instruments denominated in a foreign currency.

The following table shows how a movement in a currency would give rise to a profit or (loss) and a corresponding entry in equity.

		Profit or Loss and equity
		Strengthening				Weakening
		$'000s				$'000s
September 30, 2020
GBP (5% movement)		368				(368	)
EUR (5% movement)		(23	)			23

Foreign currency denominated trade payables are short term in nature (generally 30 to 45 days) except for the sterling element of the assumed contingent liability which is likely to become due between two and five years from the balance sheet date.

6. Critical estimates and judgements

The preparation of condensed consolidated interim financial statements require management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets and liabilities, income and expenses. Actual results may differ from those estimates.

In preparing these condensed consolidated interim financial statements, the significant judgments made by management in applying the Group’s accounting policies and the key sources of estimation uncertainty were the same as those applied to the consolidated financial statements for the year ended December 31, 2019, with the exception of development of the COVID-19 pandemic and the judgment required in determining the date that the Company's functional currency changed (see note 3).

We have assessed whether the COVID-19 pandemic has any impact on the key estimates and judgments previously reported in respect of the derivative financial instrument, the assumed contingent liability or other balances and concluded that there is no significant impact.

Total finance expense	1,858			54			2,182			149

8. Taxation

The tax credit for the nine month period ended September 30, 2020, amounts to $5.7 million and primarily consists of the estimated research and development tax credit receivable on qualifying expenditure incurred during the nine month period ended September 30, 2020 for an amount of $5.8 million less a tax expense of $0.1 million related to the U.S. operations (nine month period ended September 30, 2019: $7.6 million tax credit, comprising $7.7 million for research and development tax credit, less $45 thousand expense for tax on U.S. operations).

The tax credit for the three month period ended September 30, 2020, amounts to $2.3 million, and consists of the estimated research and development tax credit receivable on qualifying expenditure incurred during the three month period ended September 30, 2020 for an amount of $2.3 million less a tax expense of $44 thousand related to the U.S. operations (three month period ended September 30, 2019: $3.2 million tax credit, comprising $3.2 million for research and development tax credit, less $20 thousand expense for tax on U.S. operations).

9. Loss per share calculation

For the nine months ended September 30, 2020, the basic loss per share of 21.0 cents (September 30, 2019: 29.4 cents) is calculated by dividing the loss for the nine months ended September 30, 2020 by the weighted average number of ordinary shares in issue of 197,049,240 during the nine months ended September 30, 2020 (September 30, 2019: 105,326,638). Potential ordinary shares are not treated as dilutive as the entity is incurring losses and such shares would be anti-dilutive.

For the three months ended September 30, 2020, the basic loss per share of 5.8 cents (September 30, 2019: 11.8 cents) is calculated by dividing the loss for the three months ended September 30, 2020 by the weighted average number of ordinary shares in issue of 344,809,792 during the three months ended September 30, 2020 (September 30, 2019: 105,326,638). Potential ordinary shares are not treated as dilutive as the entity is incurring losses and such shares would be anti-dilutive.

Each ADS represents 8 ordinary shares of the Company, so the profit or loss per ADS in any period is equal to eight times the profit or loss per share.

In the nine months ended September 30, 2020, the Group determined that it had moved from Phase 2 of ensifentrine's clinical development plan to Phase 3. The probability of success and estimated cashflows have changed and the $27.7 million movement in the liability relating to this was recorded as an addition to the IP R&D asset that it relates to.

There were no changes in estimated cashflows or probabilities of success in 2019.

11. Right-of-use assets

In the nine months ended September 30, 2020, an office lease was signed in North Carolina and a liability and corresponding right-of-use ("ROU") asset of $703 thousand were recorded. The lease terminates on April 30, 2024.

As at December 31, 2019, the Group had an ROU asset relating to office space in New York. In the nine months ended September 30, 2020, the New York office was closed and the ROU asset was subject to an impairment review and its net book value of $290 thousand was subsequently expensed to the income statement. The Group retains a liability of $195 thousand relating to this asset.

12. Short term investments

Short term investments as at September 30, 2020, amounted to a total of $nil (December 31, 2019: $10.4 million) and in 2019 consisted of fixed term deposits.

13. Cash and cash equivalents

Included in cash and cash equivalents are cash balances held at bank, term deposits with maturities of less than three months at inception and investments in money market funds. Money market funds have been classified as cash and cash equivalents as they are low risk instruments, readily convertible to a known amount of cash and are subject to an insignificant risk of change in value. Management's intention is to manage these funds as cash and to use them to meet short term cash requirements.

14. Derivative financial instrument

On July 29, 2016, the Company issued 31,115,926 warrants, allowing the holders to subscribe for 0.4 of an ordinary share at a per share exercise price of £1.7238. The warrants can be exercised until May 2, 2022.

The warrant holders can opt for a cashless exercise of their warrants, whereby they can choose to exchange the warrants held for a reduced number of warrants exercisable at nil consideration. The reduced number of warrants is calculated based on a formula considering the share price and the exercise price of the warrants. The warrants are therefore classified as a derivative financial liability, since their exercise could result in a variable number of shares to be issued.

At September 30, 2020, and December 31, 2019, warrants over 12,401,262 shares were in effect.

Dividend rate	0.00		%		0.00		%

As of September 30, 2020, the Group updated the underlying assumptions and calculated a fair value of these warrants of $1.9 million.

The variance for the nine month period ended September 30, 2020, was $0.7 million (nine month period ended September 30, 2019: $2.7 million) and is recorded as finance income and expense in the Consolidated Statement of Comprehensive Income.

15. Assumed contingent liability related to the business combination

The value of the assumed contingent liability as of September 30, 2020, amounted to $30.6 million (December 31, 2019: $1.5 million). The increase in value of the assumed contingent liability during the nine months ended September 30, 2020, amounted to $29.1 million (nine months ended September 30, 2019: $78 thousand).

The assumed contingent liability relates to the acquisition, in 2006, of rights to certain patents and patent applications relating to ensifentrine and related compounds under which the Company is obliged to pay royalties to Ligand.

The assumed contingent liability is accounted for as a liability and its value is measured at amortized cost using the effective interest rate method, and is re-measured for changes in estimated cash flows or when the probability of success changes.

The expected cash flows are based on estimated future royalties payable, derived from sales forecasts, and an assessment of the probability of success using standard market probabilities for respiratory drug development. The risk-weighted value of the assumed contingent arrangement is discounted back to its net present value applying an effective interest rate of 12%.

Re-measurements relating to changes in estimated cash flows and probabilities of success are recognized in the IP R&D asset it relates to. The unwinding of the liability is recorded in finance expense.

As at May 13, 2020, the Group determined that it had moved from Phase 2 of ensifentrine's clinical development plan to Phase 3. As a consequence, the probability of success has changed, reducing the risk-weighting adjustment applied to estimated cashflows. Furthermore, the Group had carried out market research and updated its forecasts for ensifentrine's revenue for the maintenance treatment of chronic obstructive pulmonary disorder using a nebulized formulation in the U.S. The Group therefore updated estimated cashflows in the second quarter of 2020. In the third quarter of 2020 and in 2019 there were no events that triggered remeasurement.

There is no material difference between the fair value and carrying value of the financial liability.

For the amount recognized as at September 30, 2020, of $30.6 million, the effect if underlying assumptions were to deviate up or down is presented in the following table (assuming other variables do not change):
