Notes to Condensed Consolidated Financial Statements
(unaudited)
Note 1 - Organization and description of business operations
Verona Pharma plc (the “Company”) is incorporated and domiciled in the United Kingdom. Verona Pharma plc has 2one wholly-owned subsidiaries,subsidiary, Verona Pharma, Inc., a Delaware corporation, and Rhinopharma Limited (“Rhinopharma”), a Canadian company.corporation. The address of the registered office is 1 Central Square, Cardiff, CF10 1FS, United Kingdom.
The Company is a clinical-stage biopharmaceutical group focused on developing and commercializing innovative therapeutics for the treatment of respiratory diseases with significant unmet medical needs. The Company’s American Depositary Shares (”(“ADSs”) are listed on the Nasdaq whichGlobal Market (“Nasdaq”) and trade under the symbol “VRNA”.
In June 2023, the Company submitted a New Drug Application (“NDA”) to the U.S. Food and Drug Administration for approval of ensifentrine for the maintenance treatment of patients with chronic obstructive pulmonary disease (“COPD”) and is preparing for a potential commercial launch in 2024, subject to approval of the NDA. In conjunction with the submission, the Company paid a $3.2 million Prescription Drug User Fee Act (“PDUFA”) application fee to the FDA. The Company has requested a small business waiver of this application fee and, as such, the amount has been recorded within Other current assets in the Condensed Consolidated Balance Sheets.
Liquidity
The Company has incurred recurring losses and negative cash flows from operations since inception, and has an accumulated deficit of $228.4$359.1 million as of March 31, 2021.June 30, 2023. The Company expects to incur additional losses and negative cash flows from operations until its products potentially gain regulatory approval and reach commercial profitability, if at all.
The Company expects that its cash and cash equivalents as of March 31, 2021,June 30, 2023, will be sufficient to fund its operating expenses and capital expenditure requirements for at least the next 12 months from the date of issuance.
On March 19, 2021,During the six months ended June 30, 2023, the Company sold 20,321,384 ordinary shares (equivalent to 2,540,173 ADSs) under the at-the-market offering program entered into in March 2021 (the “2021 ATM Program”). The shares sold were at an average price of approximately $2.88 per share (equivalent to $23.08 per ADS), raising aggregate net proceeds of approximately $56.9 million after deducting issuance costs.
In March 2023, through a registration statement on Form S-3, the Company replaced the 2021 ATM Program, with an open market sale agreement with respectJefferies LLC (“Jefferies”) to sell its ordinary shares, in the form of ADSs, with aggregate gross proceeds of up to $200.0 million, from time-to-time, through an at-the-market“at the market” equity offering program (the “ATM Program”) under which Jefferies will act as sales agent (the “2023 ATM Program”). Jefferies is entitled to a commission at a rate of up to 3.0% of the gross proceeds.
The Company’s commercial revenue, if any, will be derived from sales of products that we do not expect to be commercially available within the next year, if ever. Additionally, the Company may issueenter into out-licensing transactions from time to time but there can be no assurance that the Company can secure such transactions in the future. Accordingly, the Company may need to obtain substantial additional funds to achieve its business objectives including to further advance clinical and sell its ADSs, withregulatory activities, to fund prelaunch and launch related costs and to create an aggregate offering price of upeffective sales and marketing organization to $100.0 million.commercialize ensifentrine, if approved. Any such funding will need to be obtained through public or private financings, debt financing, collaboration or licensing arrangements or other arrangements. However, there is no guarantee the Company will be successful in securing additional capital on acceptable terms, or at all.

There are no recently adopted accounting standardsIn June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326)-Measurement of Credit Losses on Financial Instruments. This guidance replaces the current incurred loss impairment methodology.
Under this model, on initial recognition and recent accounting standards not yet adoptedat each reporting period, an entity is required to recognize an allowance that reflects its current estimate of credit losses expected to be incurred over the life of the financial instrument based on historical experience, current conditions and reasonable and supportable forecasts. The guidance requires a modified retrospective transition approach through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. This update became effective for the Company believes willon January 1, 2023 and the adoption of this update did not have a material impact on the Company’s consolidated financial statements.statements and related disclosures.

Overview
We are a clinical-stage biopharmaceutical company focused on developing and commercializing innovative therapeutics for the treatment of respiratory diseases with significant unmet medical need. Our product candidate, ensifentrine, is an investigational, potential first-in-class, inhaled, selective, dual inhibitor of the enzymes phosphodiesterase 3 and 4 or PDE3(“PDE3” and PDE4, that is designed to act as both a“PDE4”), combining bronchodilator and annon-steroidal anti-inflammatory agent. activities in one compound.
Initially, we are developing inhaled ensifentrine for the treatment of chronic obstructive pulmonary disease (“COPD”), a common, chronic, progressive, and life-threatening respiratory disease without a cure. If successfully developed and approved, ensifentrine would be the first therapeutic with a novel mode of action for COPD in over a decade.
In June 2023, we submitted a New Drug Application (“NDA”) to the third quarterU.S. Food and Drug Administration (“FDA”) for approval of 2020, we commencedensifentrine for the maintenance treatment of COPD. Based on the results from our successful Phase 3 ENHANCE (“Ensifentrine as a Novel inHAled Nebulized COPD thErapy”) program, we believe ensifentrine, if approved, has the potential to change the treatment paradigm for COPD.
Also, in June 2023, the ENHANCE results were published in the peer reviewed publication, American Journal of Respiratory and Critical Care Medicine (“AJRCCM”). Ensifentrine met the primary endpoint in both the ENHANCE-1 and ENHANCE-2 trials demonstrating statistically significant and ifclinically meaningful improvements in measures of lung function. In addition, ensifentrine substantially reduced the rate and risk of COPD exacerbations in ENHANCE-1 and ENHANCE-2. Ensifentrine was well tolerated in both trials.
In May 2023, we presented 12 abstracts and a symposium on expanded analyses of the ENHANCE trials including subgroup and pooled data covering exacerbations, use of rescue medication and healthcare utilization, at the American Thoracic Society International Conference ("ATS") 2023. The abstracts were published on the ATS website and in AJRCCM.
If approved, we intend to commercialize inhaled ensifentrine for the maintenance treatment of chronic obstructive pulmonary disease (“COPD”) for the nebulized formulationCOPD in the United States.States (“U.S.”). Although we believe ensifentrine will not be regulated as a drug device combination, patients use a readily available standard jet nebulizer to take ensifentrine. Outside the U.S., we intend to license ensifentrine to companies with expertise and experience in developing and commercializing products in those regions. To that end, we have entered into a strategic collaboration with Nuance Pharma Limited, a Shanghai-based specialty pharmaceutical company (“Nuance Pharma”), to develop and commercialize ensifentrine in Greater China.
In Phase 2 clinical trials, ensifentrine has demonstrated positive results in patients with COPD, asthma and cystic fibrosis (“CF”). Two additional formulations of ensifentrine have been evaluated in Phase 2 trials for the treatment of COPD: dry powder inhaler (“DPI”) and pressurized metered-dose inhaler (“pMDI”).
We have incurred recurring losses and negative cash flows from operations since inception, and have an accumulated deficit of $228.4$359.1 million as of March 31, 2021.June 30, 2023. We expect to incur additional losses and negative cash flows from operations until our product candidates potentially gain regulatory approval and reach commercial profitability, if at all.
We anticipate that oursignificant expenses will increase significantly in connection with our ongoing activities, as we:
continue to invest in the clinical development of ensifentrine for the treatment of COPD;
manufacture ensifentrine and engage in other Chemistry, Manufacturing and Control activities;
maintain, expand and protect our intellectual property portfolio; and
enhance our commercial insights and capabilities.
12


We believe that our cash and cash equivalents as of March 31, 2021, together with funding expected to become available under the $30.0 million debt financing facility secured in November 2020 and from cash receipts from U.K. tax credits, will enable us to fund our planned operating expenses and capital expenditure requirements into 2023.
Clinical development update
In February 2021, we announced positive Phase 2 efficacy and safety data with a pressurized metered-dose inhaler (“pMDI”) formulation of ensifentrine in patients with moderate to severe COPD. The primary and secondary lung function endpoints were achieved and the data support twice-daily dosing. The ensifentrine pMDI formulation was well tolerated at each dose with an adverse event profile similar to placebo.
On April 23, 2021, we announced that data from a pilot study of the ensifentrine pMDI formulation showed that ensifentrine was well tolerated in patients infected with SARS-CoV-2, the virus that causes COVID-19. The trial was not powered to identify statistically significant efficacy outcomes and no clinical efficacy benefit with ensifentrine treatment added on to standard of care was observed in the trial. One patient death was reported in the ensifentrine treatment group. We do not currently plan to conduct further studies of ensifentrine in the treatment of COVID-19.
We have continued to enroll patients in the two Phase 3 trials underway in our ENHANCE program, and based on our projections, we continue to expect to complete enrollment in both studies in the second half of 2021 and to report top-line data from ENHANCE-2 in the first half of 2022 and from ENHANCE-1 in the second half of 2022. With the pandemic and government and other measures in response impacting a number of clinical trial activities, we are continuing to monitor these timelines.
Intellectual property update
We hold rights in the major markets relating to certain respirable formulations comprising ensifentrine for treating respiratory disorders, as well as a crystalline form of ensifentrine, combinations of ensifentrine with certain respiratory drugs, certain salts of ensifentrine, ensifentrine for use in the treatment of cystic fibrosis, and a method of making ensifentrine.
As of March 31, 2021, our patent portfolio consisted of nine issued U.S. patents, three pending U.S. patent applications, forty-eight issued foreign patents and fifty-three pending foreign applications including three patent applications made under the Patent Cooperation Treaty. These patents and patent applications include claims directed to certain respirable formulations comprising ensifentrine, a crystalline form of ensifentrine, combinations of ensifentrine with certain respiratory drugs, certain salts of ensifentrine, ensifentrine for use in the treatment of cystic fibrosis, and a method of making ensifentrine, with expected expiry dates up to 2041.
COVID-19 impact
We are closely monitoring the potential impact of the COVID-19 pandemic on our operations and clinical trials, in particular the timelines and costs of our Phase 3 clinical program. The pandemic and government and other measures in response are impacting a number of clinical trial activities and we will provide an update if we become aware of any meaningful disruption caused by the pandemic to our clinical trials.
To help protect the health and safety of the patients, caregivers and healthcare professionals involved in our clinical trials, as well as our employees and independent contractors, we continue 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.
We are closely monitoring activities at our contract manufacturers associated with clinical supply for our clinical trials, and are 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. We continue to monitor this situation and will provide an update if we become aware of any meaningful disruption caused by the pandemic to the clinical supply of ensifentrine for our clinical trials.
We have also implemented measures to help keep the our employees, families, and local communities healthy and safe. All employees are working remotely and all business travel has been restricted.

Significant contracts
Ligand agreement
In 2006 we acquired Rhinopharma and assumed contingent liabilities owed to Ligand UK Development Limited (“Ligand”) (formerly Vernalis Development Limited). We refer to the assignment and license agreement as the Ligand Agreement.
Ligand assigned to us all of its rights to certain patents and patent applications relating to ensifentrine and related compounds (the “Ligand Patents”) and an exclusive, worldwide, royalty-bearing license under certain Ligand know-how to develop, manufacture and commercialize products (the ”Licensed Products”) developed using Ligand Patents, Ligand know-how and the physical stock of certain compounds.
The contingent liability comprises a milestone payment on obtaining the first approval of any regulatory authority for the commercialization of a Licensed Product, low single digit royalties based on the future sales performance of all Licensed Products and a portion equal to a mid-twenty percent of any consideration received from any sub-licensees for the Ligand Patents and for Ligand know-how.
At time of the acquisition the contingent liability was not recognized as part of the acquisition accounting as it was immaterial. We will therefore record as a research and development expense the milestone payment or royalties when they are payable.
Warrants
On July 29, 2016, as part of a private placement we issued warrants to investors. The warrant holders can subscribe for an ordinary share at a per share exercise price of £1.7238. They can also 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.
If, after a transaction, should the warrants be exercisable for unlisted securities, the warrant holders may demand a cash payment instead of the delivery of the underlying securities. Accordingly, they are accounted for as a liability under ASC 480 “Distinguishing Liabilities from Equity” and recorded at fair value using the Black-Scholes valuation methodology, on recognition and at each reporting date. The warrants are currently exercisable and may be exercised by the holders until April 2022 when the warrant instruments may either be exercised, cashlessly exercised, or expire.
Loan and security agreement
In November 2020 we entered into the Term Loan. See “Indebtedness” for additional information.
Critical accounting policies and significant judgments and estimates
The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, the accrual and prepayment of research and development expenses, the fair value of share-based compensation and the fair value of warrants. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from our estimates. The accounting policies considered to be critical to the judgments and estimates used in the preparation of our financial statements are disclosed in the Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our 2020 Form 10-K. There have been no material changes to that information disclosed in our 2020 Form 10-K during the three months ended March 31, 2021.

Components of results of operations
We anticipate that our expenses will increase substantially if and as we:
conductestablish a sales, marketing and distribution infrastructure, ramp up production to commercial scale with our ongoing Phase 3 clinical trialsmanufacturing and other Chemistry, Manufacturing and Controls activities to potentially commercialize any products for ensifentrine for the maintenance treatment of COPD;which we may obtain regulatory approval;
continue the clinical development of our DPI and pMDI formulations of ensifentrine and research and develop other formulations of ensifentrine;
initiate and conduct further clinical trials for ensifentrine for the treatment of acute COPD, CF or any other indication;
initiate and progress pre-clinical studies relating to other potential indications of ensifentrine;
seek to discover and develop additional product candidates;
seek regulatory approvals for any of our product candidates that successfully complete clinical trials;
potentially establish a sales, marketing and distribution infrastructure and scale-up manufacturing capabilities to commercialize any products for which we may obtain regulatory approval;
maintain, expand and protect our intellectual property portfolio;
13


add clinical, scientific, operational, financial and management information systems and personnel, including personnel to support our product development and potential future commercialization efforts and to support our continuing operations as a U.S. public company; orand
experience any delays or encounter any issues from any of the above, including but not limited to failed studies, complex results, safety issues or other regulatory challenges.
We believe that our cash and cash equivalents as of June 30, 2023, together with expected cash receipts from U.K. tax credit program and funding expected to become available under the $150.0 million debt financing facility secured in October 2022 (the “Oxford Term Loan”), will enable us to fund our planned operating expenses and capital expenditure requirements through at least the end of 2025, including the planned commercial launch of ensifentrine in the U.S., if approved. The Oxford Term Loan advances are contingent upon achievement of certain clinical and regulatory milestones and other specified conditions. Refer to Note 5 - Term Loan for additional information on the Oxford Term Loan.

Clinical development update
Phase 3 ENHANCE program
We reported positive top-line results from ENHANCE-2 and ENHANCE-1, in August and December 2022, respectively. Ensifentrine successfully met the primary endpoints in both trials, demonstrating statistically significant and clinically meaningful improvements in measures of lung function in moderate to severe COPD patients. Improvements in symptoms and quality of life measures were shown in both trials, which reached statistical significance in ENHANCE-1. Ensifentrine substantially reduced the rate and risk of moderate to severe COPD exacerbations and was well tolerated in both trials.
The ENHANCE trials were designed to evaluate ensifentrine as monotherapy and added onto a single bronchodilator. Each trial enrolled approximately 800 subjects, for a total of approximately 1,600 subjects, at sites primarily in the U.S. and Europe. The two trials provided replicate evidence of efficacy and safety data over 24 weeks and ENHANCE-1 also evaluated longer-term safety in approximately 400 subjects over 48 weeks.
Subject demographics and disease characteristics were well balanced between treatment groups in both trials.
In ENHANCE-1 approximately 69% of subjects received background COPD therapy, either a long-acting muscarinic antagonist (“LAMA”) or a long-acting beta-antagonist (“LABA”). Additionally, approximately 20% of all subjects received inhaled corticosteroids (“ICS”) with concomitant LAMA or LABA.
In ENHANCE-2 approximately 55% of subjects received background COPD therapy, either a LAMA or a LABA. Additionally, approximately 15% of all subjects received ICS with concomitant LAMA or LABA.
Highlights
Primary endpoint met (FEV1*AUC 0-12 hr)
Placebo corrected, change from baseline in average FEV1 area under the curve 0-12 hours post dose at week 12 was 87 mL (p<0.0001) for ensifentrine in ENHANCE-1 and 94 mL (p<0.0001) for ensifentrine in ENHANCE-2.
Demonstrated consistent improvements with ensifentrine in all subgroups including gender, age, smoking status, COPD severity, background medication, ICS use, chronic bronchitis, FEV1 reversibility and geographic region.
Secondary endpoints evaluating lung function met:
Placebo corrected, increase in peak FEV1 of 147 mL (p<0.0001) 0-4 hours post dose at week 12 in ENHANCE-1 and 146 mL (p<0.0001) in ENHANCE-2.
Placebo corrected, increase in morning trough FEV1 of 35 mL (p=0.0413) at week 12 in ENHANCE-1 and 49 mL (p=0.0016) in ENHANCE-2, supporting twice daily dosing regimen.
Exacerbation rate and risk reduced
Subjects receiving ensifentrine demonstrated a 36% reduction in the rate of moderate to severe COPD exacerbations over 24 weeks (p=0.0503) compared to those receiving placebo in ENHANCE-1 and a 43% reduction (p=0.0090) in ENHANCE-2.
In pooled exacerbation data from ENHANCE-1 and ENHANCE-2, ensifentrine demonstrated a 40% reduction in the rate of moderate to severe COPD exacerbations over 24 weeks (p=0.0012) compared to those receiving placebo.
Treatment with ensifentrine significantly decreased the risk of a moderate/severe exacerbation as measured by time to first exacerbation when compared with placebo by 38% (p=0.0382) in ENHANCE-1 and by 42% (p=0.0089) in ENHANCE-2.
In pooled exacerbation data from ENHANCE-1 and ENHANCE-2, ensifentrine significantly decreased the risk of a moderate/severe exacerbation as measured by time to first exacerbation when compared with placebo by 41% (p=0.0009).

Operating expensesIn ENHANCE-1, daily symptoms as measured by E-RS** Total Score in the ensifentrine group improved from baseline to greater than the minimal clinically important difference (“MCID”) of -2 units with a statistically significant improvement compared to placebo at week 24. Improvements in symptoms were early and sustained with statistical significance versus placebo at weeks 6, 12 and 24. Similar improvements were demonstrated in ENHANCE-2 but statistical significance was not achieved due to improvements observed in the placebo group over time.
In ENHANCE-1, QOL as measured by SGRQ** Total Score in the ensifentrine group improved from baseline to greater than the MCID of -4 units with a statistically significant improvement compared to placebo at week 24. Improvements in QOL were early and sustained with statistical significance versus placebo at weeks 6, 12 and 24. In ENHANCE-2, QOL as measured by SGRQ* Total Score in the ensifentrine group also improved from baseline to greater than the MCID of -4 units at weeks 12 and 24, numerically exceeding placebo at each measurement, but statistical significance was not achieved due to improvements observed in the placebo group over time.
Favorable safety profile
Ensifentrine was well tolerated with very few adverse events occurring in more than 1% of subjects and greater than placebo over 24 and 48 weeks.

Nuance Pharma
In 2021, we entered into an agreement with Nuance Pharma for exclusive rights to develop and commercialize ensifentrine in Greater China, with future potential milestone payments up to $179 million plus royalties. In August 2022, Nuance Pharma received clearance from the Center of Drug Evaluation for its Investigational New Drug application to conduct both Phase 1 and Phase 3 studies with ensifentrine for the maintenance treatment of COPD in mainland China. Nuance Pharma initiated a Phase 1 trial with ensifentrine in healthy volunteers in March 2023. In

Critical accounting estimates
There were no material changes to the Company’s critical accounting estimates described in the Company’s 2022 Form 10-K during the six months ended June 30, 2023.
Components of results of operations
Research and development costs
Research and development costs consist of salary and personnel related costs and third party costs for our research and development activities for ensifentrine. Personnel related costs include a share-based compensation charge relating to our stock option plan. The largest component of third party costs is for clinical trials, as well as manufacturing for clinical supplies and associated development, and pre-clinical studies. Research and development costs are expensed as incurred.
WeAs the Phase 3 ENHANCE program has completed study conduct and analysis, we expect our research and development costs to significantly increasedecrease over the next several quarters until we add new compounds or develop ensifentrine further in the near future as we progress our ENHANCE program.other delivery methods or indications. Due to the nature of research and development, the expected costs are inherently uncertain and may vary significantly from our current expectations.
GeneralSelling, general and administrative costs
GeneralSelling, general and administrative costs consist of salary and personnel related costs, including share-based compensation, expenses relating to operating as a public company, including professional fees, insurance and commercial related costs, as well as other operating expenses.
We expect commercial costs to increase as we continue to develop our potential commercial operations, prepare for a potential launch and, in the event of successful regulatory approval, we expect to incur sales force, marketing and other launch related costs. As we develop our knowledge of the market and refine our commercialization plans, expected costs may vary significantly from our current expectations.
Other income / income/(expense)
Other income / income/(expense) are driven by interest income and expense, the fair value movement of the warrant liability, foreign exchange movements on cash and cash equivalents and taxes receivable, and the U.K. research and development tax credits.credits (the “R&D tax credit”).
We are entitled to participate in the U.K. Small and Medium Enterprises research and development tax relief program. The tax credits are calculated as a percentage of qualifying research and development expenditure and are payable in cash by the U.K. government to the Company.us. Credits recorded in the 20212022 financial year are expected to be received in the 2022 financial year.
The U.K. tax authorities have reviewed legislation and have proposed to cap the amount payable in the program to a multiplefourth quarter of employment taxes a company pays in the year in question, from January 1, 2022. We are currently reviewing recent clarifications to these proposed changes to review the effect on our financing strategy. It is possible that our tax credit for the 2022 financial year, payable in 2023, will be impacted by the cap. If the legislation is enacted as currently drafted, we estimate the potential cash received under this program could be approximately $6 million lower than before the changes.2023.

Additionally, we recorded a $6.3 million reversal of costs, accrued primarily in the three months ended March 31, 2020,2023, related to the resolution of a supplier matter and certain invoices, as discussed in Note 8 - Commitments and contingencies, which resulted in net negative research and development expense for the three months ended June 30, 2023.
Selling, general and administrative costs

This increase was primarily due to a $5.0 million increase in people related costs, inclusive of share-based compensation, as well as an increase of $1.7 million for costs related to the build out of commercial and information technology infrastructure in preparation for a potential commercial launch.
Other income/(expense)
Other income/(expense) for the three months ended June 30, 2023 was income of $1.5 million compared to income of $2.8 million for the three months ended June 30, 2022, a decrease of $1.4 million. This decrease was primarily due to a net reversal in the current period related to the R&D tax credit of $1.9 million resulting from the reversal in clinical trial and other development costs. Additionally, the R&D tax credit in the same period in the prior year was higher as it included the full credit for expenditures made in the second quarter of the prior year as well as an increase in the credit for expenditures made in the first quarter of the prior year based upon feedback from HM Revenue & Customs in July 2022 that a cap on the credit which was previously applied was not applicable to us. This was partially offset by increases of $3.2 million in interest income from higher cash balances and higher interest rates and $3.4 million increaserelated to the strengthening of the pound sterling in the current period while the pound sterling weakened in the second quarter of the prior year.

Other income / (expense)
The research and development tax credit for the three months ended March 31, 2021 was $2.1 million compared to a credit of $1.7 million for the three months ended March 31, 2020, an increase of $0.4 million. This increase is attributable to our higher qualifying expenditure on research and development in the three months ended March 31, 2021, compared to the comparative 2020 period, as we are randomizing patients in our Phase 3 trials.
We recorded an expense of $0.5 million in the three months ended March 31, 2021, compared to a gain of $0.1 million in the comparative period relating to the fair value movements of the warrants, driven by the rise and fall of our share price in each period respectively, as in increase in the share price increases the fair value of the warrants.
Net loss
Net loss was $21.3 million for the three months ended March 31, 2021, compared to $12.3 million for the three months ended March 31, 2020. The increase in net loss was primarily the result of the increase in operating costs and the fall in other income, net, discussed above.

Open market sale agreement
On March 19, 2021,weSold 20,321,384 ordinary shares (equivalent to 2,540,173 ADSs) under the at-the-market offering program entered into in March 2021 (the “2021 ATM Program”), at an average price of approximately $2.88 per share (equivalent to $23.08 per ADS), raising aggregate net proceeds of approximately $56.9 million after deducting issuance costs;
Replaced the 2021 ATM Program with an open market sale agreement with Jefferies LLC (“Jefferies”) to sell shares of our ordinary shares, in the form of ADSs, with aggregate gross sales proceeds of up to $100.0 million, from time$200.0 million.

Ascondensed consolidated financial statements for additional information on the Oxford Term Loan and to Note 1 - Organization and description of March 31, 2021, we had not sold any sharesbusiness operations for additional information on 2023 activity under the 2021 ATM Program.
Indebtedness
In November, 2020, we and Verona Pharma, Inc. entered into a term loan facility of up to $30.0 million with Silicon Valley Bank (the “Term Loan”), consisting of term loan advances in an aggregate amount of $5.0 million funded at closing, a term loan advance of an aggregate amount of $10.0 million available subject to certain terms and conditions and the achievement of a specific clinical milestone, and a term loan advance of an aggregate amount of $15 million contingent upon achievement of a specific clinical development milestone and other specified conditions. As at March 31, 2021, the Company had $5.0 million principal outstanding under the Term Loan. Additional detail surrounding the Term Loan is included under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2020 Form 10-K. There have been no material changes to that information disclosed in our 2020 Form 10-K during the three months ended March 31, 2021.
Funding requirements
We believe that our cash and cash equivalents as of March 31, 2021,June 30, 2023, together with, expected cash receipts from U.K. tax credits and together withadditional funding expected to become available under both the Oxford Term Loan, and from cash receipts from U.K. tax credits will enable us to fund our planned operating expenses and capital expenditure requirements into 2023. Thethrough at least the end of 2025, including the planned commercial launch of nebulized ensifentrine for COPD maintenance treatment in the U.S. Future advances under the Oxford Term Loan advances are contingent upon achievement of certain clinical developmentand regulatory milestones and other specified conditions. Our cash and cash equivalents are maintained at financial institutions in amounts that exceed federally insured limits. In the event of failure of any of the financial institutions where we maintain our cash and cash equivalents, there can be no assurance that we will be able to access uninsured funds in a timely manner or at all.
We willmay require significant additional capital to further advancecommercialize ensifentrine, to continue the clinical development of our DPI and regulatory activities, to fund prelaunch and launch related costspMDI formulations of ensifentrine and to create an effective salesresearch and marketing organizationdevelop additional formulations of or with ensifentrine. In addition, we may seek to commercialize ensifentrine.initiate or conduct preclinical or clinical studies with ensifentrine in additional indications or to discover or in-license and develop additional product candidates. We willmay need to seek additional funding through public or private financings, debt financing, collaboration or licensing agreements and other arrangements. However, there is no guarantee that we will be successful in securing additional financecapital on acceptable terms, or at all.
To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our shareholders and ADS holders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect such holders’ rights as a shareholder or ADS holder. Any future debt financing or preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends and may require the issuance of warrants, which could potentially dilute our security holders’ ownership interests.
If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product

development programs or any future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.
Our future capital requirements for ensifentrine or any future product candidates will depend on many factors, including:
the progress, timing and completion of pre-clinical testing and clinical trials for ensifentrine or any future product candidates and the potential that we may be required to conduct additional clinical trials for ensifentrine;
the number of potential new product candidates we decide to in-license and develop;
the costs involved in growing our organization to the size needed to allow for the research, development and potential commercialization of ensifentrine or any future product candidates;
the costs involved in filing patent applications and maintaining and enforcing patents or defending against claims or infringements raised by third parties;
19


the time and costs involved in obtaining regulatory approvals for ensifentrine or any future product candidate we develop and any delays we may encounter as a result of evolving regulatory requirements or adverse results with respect to ensifentrine or any future product candidates;
any licensing or milestone fees we might have to pay during future development of ensifentrine or any future product candidates;
selling and marketing activities undertaken in connection with the anticipated commercialization of ensifentrine or any future product candidates, if approved, and costs involved in the creation of an effective sales and marketing organization; and
the amount of revenues,revenue, if any, we may derive either directly or in the form of royalty payments from future sales of ensifentrine or any future product candidates, if approved.
Our commercial revenues,revenue, if any, will be derived from sales of products that we do not expect to be commercially available for many years,within the next year, if ever. Accordingly, we willmay need to obtain substantial additional funds to achieve our business objective.objectives.
Off-balance sheet arrangements
22
We do not have any relationships with unconsolidated entities or financial partnerships, including entities sometimes referred to as structured finance or special purpose entities that were established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. We do not engage in off-balance sheet financing arrangements. In addition, we do not engage in trading activities involving non-exchange traded contracts. We therefore believe that we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in these relationships.

Item 1A.    Risk Factors
Our business is subject to risks and events that, if they occur, could adversely affect our financial condition and results of operations and the trading price of our securities. OurExcept as discussed below, our risk factors have not changed materially from those described in Part I, Item 1A of the 20202022 Form 10-K under the heading “Risk Factors”.
We will need additional funding to complete development and commercialization of any future product candidates, or development and commercialization of other formulations or target indications of ensifentrine, if approved. If we are unable to raise capital when needed, or if a failure of any financial institution where we maintain our cash and cash equivalents prevents or delays us from accessing uninsured funds, we could be forced to delay, reduce or eliminate our product development programs or commercialization efforts.
We expect our expenses to increase in connection with our ongoing and planned activities, particularly as we conduct further clinical trials of ensifentrine, and develop ensifentrine in other formulations or for other indications. In addition, if we obtain regulatory approval for ensifentrine or any other product candidates, we expect to incur significant commercialization expenses related to activities including product positioning studies, product manufacturing, medical affairs, marketing, sales and distribution. Furthermore, we expect to incur ongoing costs associated with operating as a public company in the United States and maintaining a listing on the Nasdaq Global Market, or Nasdaq. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts.
If we obtain regulatory approval for ensifentrine for the treatment of COPD in the US, we estimate that our existing cash resources, expected cash receipts from the UK tax credit program and funding expected to become available under the $150.0 million debt facility will enable the Company to fund planned operating expenses and capital expenditure requirements through at least the end of 2025 including the commercial launch of ensifentrine in the US. Future advances under the Oxford Term Loan are contingent upon achievement of certain clinical and regulatory milestones and other specified conditions. We have based this estimate on assumptions that may prove to be incorrect, and we could use our available capital resources sooner than we currently expect. In addition, our operating plan may change as a result of many factors unknown to us. These factors, among others, may necessitate that we seek additional capital sooner than currently planned. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. We maintain the majority of our cash and cash equivalents in accounts with major U.S. and multi-national financial institutions, and our deposits at these institutions exceed insured limits. Market conditions can impact the viability of these institutions. In the event of failure of any of the financial institutions where we maintain our cash and cash equivalents, there can be no assurance that we would be able to access uninsured funds in a timely manner or at all. Any inability to access or delay in accessing these funds could adversely affect our business and financial position.
Our future capital requirements will depend on many factors, including:
the costs, timing and outcome of the regulatory submission and review of ensifentrine for the treatment of COPD in the US and other regions, including any post-marketing studies that could be required by regulatory authorities, if regulatory approval is received;
the cost, progress and results of any other studies required to support the commercial positioning of ensifentrine for the treatment of COPD, if regulatory approval is received;
the cost, progress and results of any clinical trials for the treatment of CF, asthma or other indications, or for other formulations of ensifentrine including fixed-dose combination products;
the cost of manufacturing clinical and, if approved, commercial supplies of the ensifentrine active ingredient and derived formulated drug products;
24


the scope, progress, results and costs of pre-clinical development, laboratory testing and clinical trials for ensifentrine in other indications and of the development of DPI and pMDI formulations of ensifentrine, or fixed-dose combination formulations of ensifentrine for the maintenance treatment of COPD and potentially asthma and other respiratory diseases;
the costs, timing and outcome of potential future commercialization activities, including manufacturing, marketing, sales and distribution, for ensifentrine;
the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims, including any claims by third parties that we are infringing upon their intellectual property rights;
the timing and amount of revenue, if any, received from commercial sales of ensifentrine;
the sales price and availability of adequate third-party coverage and reimbursement for ensifentrine;
the effect of competing technological and market developments; and
the extent to which we acquire or invest in businesses, products and technologies, including entering into licensing or collaboration arrangements for ensifentrine, although we currently have no commitments or agreements to complete any such transactions.
Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize ensifentrine. In addition, we cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all. Moreover, the terms of any financing may adversely affect our business, the holdings or the rights of our shareholders, or the value of our ordinary shares or ADSs.
If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay or discontinue our research and development programs relating to ensifentrine or any commercialization efforts, be unable to expand our operations, or be unable to otherwise capitalize on our business opportunities, as desired, which could harm our business and potentially cause us to discontinue operations.
