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, dual
inhibitor of the enzymes phosphodiesterase 3 and 4 ("PDE3" and "PDE4"), which is
designed to act as both a bronchodilator and an anti-inflammatory agent.

In the third quarter of 2020, we commenced our Phase 3 ENHANCE ("Ensifentrine as
a Novel inHAled Nebulized COPD thErapy") trials evaluating nebulized
ensifentrine for the maintenance treatment of chronic obstructive pulmonary
disease ("COPD"). In August 2022, we announced positive top-line results from
the ENHANCE-2 trial. ENHANCE-2 successfully met its primary endpoint, as well as
secondary endpoints demonstrating improvements in lung function, and
significantly reduced the rate and risk of COPD exacerbations. Ensifentrine was
well tolerated with safety results similar to placebo.

We expect to report top-line results from ENHANCE-1 around the end of 2022. Conditional upon positive results, we plan to submit a New Drug Application ("NDA") to the US Food and Drug Administration ("FDA") in the first half of 2023 for inhaled ensifentrine for the maintenance treatment of COPD.



We have incurred recurring losses and negative cash flows from operations since
inception, and have an accumulated deficit of $322.4 million as of September 30,
2022. 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 significant expenses in connection with our ongoing activities, as we:

•build out infrastructure and prepare for potential commercial launch;

•continue to invest in the clinical development of ensifentrine for the treatment of COPD or other indications;

•manufacture ensifentrine and engage in other Chemistry, Manufacturing and Controls activities; and

•maintain, expand and protect our intellectual property portfolio.



We believe that our cash and cash equivalents as of September 30, 2022, together
with expected cash receipts from U.K. tax credits and additional funding
expected to become available under the new Oxford Term Loan secured in October
2022, 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. See "Indebtedness" for additional
information.

Clinical development update

ENHANCE-2



In August 2022, we announced positive top-line results from our Phase 3
ENHANCE-2 clinical trial evaluating nebulized ensifentrine for the maintenance
treatment of COPD. ENHANCE-2 successfully met its primary endpoint, as well as
secondary endpoints demonstrating improvements in lung function, and
significantly reduced the rate and risk of COPD exacerbations.

Highlights


•Study population (n=789):
•Subject demographics and disease characteristics were well balanced between
treatment groups.
•Approximately 52% of subjects received background COPD therapy, either a
long-acting muscarinic antagonist ("LAMA") or a long-acting beta-agonist
("LABA"). Additionally, approximately 15% of all subjects also received inhaled
corticosteroids ("ICS") with concomitant LAMA or LABA.
•Primary endpoint met (FEV1* AUC 0-12 hr):
•Placebo corrected, the change from baseline in average FEV1 area under the
curve 0-12 hours post dose at week 12 was 94 mL (p<0.0001) for ensifentrine.
•Statistically significant and clinically meaningful improvements with
ensifentrine demonstrated across all subgroups including gender, age, smoking
status, COPD severity, background medication, ICS use, chronic bronchitis, FEV1
reversibility, and geographic region.
•Secondary endpoints of lung function met:
•Placebo corrected, increase in peak FEV1 of 146 mL (p<0.0001) 0-4 hours post
dose at week 12.
•Placebo corrected, increase in morning trough FEV1 of 49 mL (p=0.0017) at week
12, confirming twice daily dosing regimen.
•Exacerbation rate reduced:
•Subjects receiving ensifentrine demonstrated a 42% reduction in the rate of
moderate to severe COPD exacerbations over 24 weeks compared to those receiving
placebo (p=0.0109).
•Treatment with ensifentrine significantly decreased the risk of a
moderate/severe exacerbation as measured by time to first exacerbation when
compared with placebo by 42% (p=0.0088).
•COPD symptoms and Quality of Life ("QOL"):
•Daily symptoms and QOL as measured by E-RS** Total Score and SGRQ** Total Score
in the ensifentrine group improved from baseline to greater than the minimal
clinically important difference ("MCID") of -2 units and -4 units, respectively,
at week 24. Improvements in these measures were seen as early as 6 weeks and
showed continued improvement at 12 and 24 weeks, numerically exceeding placebo
at each measurement. Statistical significance was not achieved due to
improvements observed in the placebo group over time.
•Favorable safety profile:
•Ensifentrine was well tolerated with safety results similar to placebo,
including occurrence of pneumonia, gastrointestinal and cardiovascular adverse
events.

*FEV1: Forced Expiratory Volume in one second, a standard measure of lung function

**E-RS, Evaluating Respiratory Symptoms, and SGRQ, St. George's Respiratory Questionnaire, are validated patient reported outcome tools



In October 2022, we announced positive additional analyses from the ENHANCE-2
trial demonstrating that ensifentrine reduced rates of exacerbation across all
subgroups analyzed over 24 weeks, including background medication, ICS use,
smoking status and geographic region. Results of the subgroup analyses confirmed
positive effects consistent with the 42% reduction in the rate of moderate to
severe exacerbations observed in the overall population. ENHANCE-2 was not
powered for exacerbation rate.

We plan to release additional information from ENHANCE-2 at upcoming scientific conferences.




                                       18
--------------------------------------------------------------------------------

ENHANCE-1



In June 2022, we completed enrollment in our Phase 3 ENHANCE-1 clinical trial
with more than 800 patients randomized. Based on our current models of study
progress, we expect to report top-line data for ENHANCE-1 around the end of
2022.

The two randomized, double-blind placebo-controlled studies (ENHANCE-1 and
ENHANCE-2) evaluate the efficacy and safety of nebulized ensifentrine in
subjects with COPD as monotherapy and added onto a single bronchodilator, either
a LAMA or a LABA, compared to placebo, and up to approximately 20% of subjects
may receive ICS. The two study designs replicate measurements of efficacy and
safety data over 24 weeks and ENHANCE-1 also evaluates longer-term safety over
48 weeks. The primary endpoint of both studies is improvement in lung function,
as measured by FEV1 area under curve ("AUC") 0-12 hours post dose at week 12.
Key secondary endpoints comprise measurements of COPD symptoms and
health-related quality of life measures, including SGRQ and E-RS.

The design of the ENHANCE program was based on analysis of our two Phase 2b
clinical trials, which each enrolled 400 subjects with moderate to severe COPD.
The attributes of the patient population enrolled in the ENHANCE program are
consistent with those enrolled in prior Phase 2b trials of ensifentrine
including demographics and baseline COPD characteristics, including smoking
history, lung function, symptoms and quality of life measures.

Nuance Pharma



In August 2022, our development partner, Nuance Pharma, received clearance from
China's Center for Drug Evaluation to begin Phase 1 and Phase 3 studies with
ensifentrine for COPD in mainland China. In 2021, we entered into an agreement
with Nuance Pharma with a potential value of up to $219 million, granting Nuance
Pharma exclusive rights to develop and commercialize ensifentrine in Greater
China. See "Significant Agreements" for additional information.

COVID-19 pandemic impact



Whilst the impact of the COVID-19 pandemic and government and other measures in
response have substantially reduced, we continue to monitor the pandemic and any
potential impact on our operations and clinical trials. In addition, we continue
to follow guidance from the FDA and other health regulatory authorities
regarding the conduct of clinical trials during the pandemic to ensure the
safety of study participants, minimize risks to study integrity, and maintain
compliance with good clinical practice.

Russia-Ukraine conflict



We are conducting ENHANCE-1 at a number of clinical trial sites in Russia. The
sanctions and other restrictions imposed by the U.S. and other countries as a
result of the current conflict between Russia and Ukraine are impacting our
outsourced clinical research vendor's ability to pay the clinical trial sites
and investigators in Russia and may impact our clinical trial activities at
sites in Russia. Management is closely monitoring the Russia-Ukraine conflict
and will provide an update if we become aware of any meaningful disruption to
the completion of our Phase 3 program or our plans to submit an NDA for
ensifentrine.

Management update



Following the positive data from ENHANCE-2, we accelerated our commercial launch
preparation activities. We are executing on our strategy and, in September and
October 2022, we added senior leadership across marketing, market access,
commercial operations, IT, HR and finance.

Significant agreements

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 "Ligand
Licensed Products") developed using Ligand Patents, Ligand know-how and the
physical stock of certain compounds.

The contingent liability comprises a milestone payment (the "Milestone Payment")
on obtaining the first approval of any regulatory authority for the
commercialization of a Ligand Licensed Product, low single digit royalties based
on the future sales performance of all Ligand 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 probable.

In March 2022 we entered into an Amendment Agreement (the "Amendment") with Ligand whereby the Ligand Agreement was amended to clarify certain ambiguous terms in the Ligand Agreement. Pursuant to the Amendment:



•we agreed to pay to Ligand (i) $2.0 million within five business days of the
date of the Amendment and (ii) $15.0 million upon the first commercial sale of
ensifentrine by us or a sub-licensee, which amount is payable in cash or, at the
our discretion, by the issuance of Company equity of equivalent value, as
determined based on the volume-weighted average price of the our American
Depositary Shares on the Nasdaq Global Market over the ten (10) trading days
including and prior to such milestone event;

•the Ligand Agreement shall expire on March 24, 2042 unless terminated earlier by either party in accordance with its terms;



• upon termination of the Ligand Agreement, any Sub-licensee (as defined in the
Amendment) shall have the right to enter into a direct license agreement with
Ligand for the portion of the Program IP (as defined in the Amendment) that was
sub-licensed by such Sub-licensee;

•the Milestone Payment may be paid in cash or, at our discretion, by issuing to Ligand shares in the Company of equivalent value; and



•each party's right to terminate the Ligand Agreement is conditioned upon such
party obtaining a final judgment of the English High Court declaring that the
other party is in material breach of its obligations under the Ligand Agreement.

Nuance agreement



We entered into a collaboration and license agreement (the "Nuance Agreement")
with Nuance Pharma Limited ("Nuance Pharma") effective June 9, 2021 (the
"Effective Date") under which we granted Nuance Pharma the exclusive rights to
develop and commercialize ensifentrine in Greater China (China, Taiwan, Hong
Kong and Macau). In return, we received an unconditional right to consideration
aggregating $40.0 million consisting of $25.0 million in cash and an equity
interest valued at $15.0 million as of the Effective Date in Nuance Biotech, the
parent company of Nuance Pharma. We are eligible to receive future milestone
payments of up to $179.0 million, triggered upon achievement of certain
clinical, regulatory, and commercial milestones as well as tiered double-digit
royalties on net sales in Greater China.

As of September 30, 2021, the $25.0 million cash payment and $15.0 million
equity interest had been received and the holding in Nuance Biotech was recorded
as Equity Interest on our unaudited condensed consolidated balance sheet. The
equity interest is recorded at the fair value indicated by the last observable
transaction in Nuance Biotech's stock, which was a fund raising in November,
2020. As of September 30, 2022, there had been no other observable transactions
to indicate any price changes in the value of Nuance Biotech's stock, nor had
there been any indications of impairment. The equity interest is therefore
recorded at a value of $15.0 million.

Nuance Pharma will be responsible for all costs related to clinical development and commercialization of ensifentrine in Greater China. A joint steering committee has been established between us and Nuance Pharma to


                                       20
--------------------------------------------------------------------------------

oversee and coordinate the overall conduct of such clinical development and commercialization. We intend to use the joint steering committee to help ensure the clinical development of ensifentrine in Greater China aligns with our overall global development and commercialization strategy.



Under the terms of the Nuance Agreement, at any time until three months prior to
the expected submission of the first New Drug Application in Greater China, if
(i) a third party is interested in partnering with us, either globally or in
territory covering at least the United States or Europe, for the development
and/or commercialization of ensifentrine or (ii) we undergo a change of control,
we will have an exclusive option right to buy back the license granted to Nuance
Pharma and all related assets. The price is agreed to be equal to the aggregate
of (i) all prior amounts paid by Nuance Pharma to us in cash under the agreement
and (ii) all development and regulatory costs incurred and paid by Nuance Pharma
in connection with the development and commercialization of the ensifentrine
under the Nuance Agreement multiplied by a single-digit factor range dependent
upon achievement of certain milestones, subject to a specified maximum amount.

The Nuance Agreement will continue on a jurisdiction-by-jurisdiction and
product-by-product basis until the expiration of royalty payment obligations
with respect to such product in such jurisdiction unless earlier terminated by
the parties. Either party may terminate the Nuance Agreement for an uncured
material breach or bankruptcy of the other party. Nuance Pharma may also
terminate the Nuance Agreement at will upon 90 days' prior written notice.

We reviewed the buy-back option and determined that because it is conditional on a third party we do not have the practical ability to exercise it and, accordingly, the contract is accounted for under ASC 606.



The transaction price at the Effective Date of the Nuance Agreement was $40.0
million consisting of the $25.0 million upfront cash payment and $15.0 million
equity interest. Developmental and regulatory milestones, and the manufacture
and supply of ensifentrine drug product, were not included in the transaction
price as we determined that it is not probable that a significant reversal in
the amount of cumulative revenue recognized will not occur. Commercial
milestones and sales royalties were also excluded and will be recognized when
the milestones are achieved or the sales occur in Greater China.

The performance obligations in the Nuance Agreement include the grant of the
license (including the right to commercialize ensifentrine until the end of the
term, the sharing of certain know how, and the sharing of certain clinical and
regulatory data), and manufacture and supply of ensifentrine drug product. We
have determined that the manufacturing and supply was not at a discount.

We have determined that the license and the know how shared with Nuance Pharma
constitutes functional intellectual property and that revenue relating to this
should be recognized at a point in time. Consequently, we have determined that
we fulfilled our obligations to Nuance Pharma when we delivered the know how
that will allow Nuance Pharma to file an investigational new drug application in
Greater China. We delivered this know-how in the year ended December 31, 2021,
and the $40.0 million revenue was therefore recognized as revenue in the year
ended December 31, 2021. Revenue relating to the manufacture and supply
obligations will be recognized when the drug product is delivered.

For additional information regarding the Nuance Agreement, see Note 6 to our
unaudited condensed consolidated financial statements and related notes included
elsewhere in this Quarterly Report on Form 10-Q.

Warrants



On July 29, 2016, as part of a private placement we issued warrants to
investors. The warrant holders could subscribe for an ordinary share at a per
share exercise price of £1.7238. They could also opt for a cashless exercise of
their warrants whereby they could 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 were able to demand a cash payment instead of
the delivery of the underlying securities. Accordingly, they were 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 were exercisable by the
holders until May 2, 2022. None of the warrants were exercised prior to their
expiration.

Loan and security agreement

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 "SVB Term Loan"). Subsequent
to the quarter end, on October 14, 2022, we and Verona Pharma, Inc. entered into
a term loan (the "Oxford Term Loan") of up to $150.0 million with Oxford Finance
Luxembourg

                                       21
--------------------------------------------------------------------------------

S.À R.L. ("Oxford"). This Oxford Term Loan replaced the existing term loan with Silicon Valley Bank. See "Indebtedness" for additional information.

Critical accounting estimates



The preparation of consolidated financial statements in conformity with
accounting principles generally accepted in the U.S. ("U.S. 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
recognition of revenue, the accrual and prepayment of research and development
expenses, the fair value of share-based compensation, the carrying value of the
equity interest in Nuance Pharma, research and development tax credit 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 2021 Form 10-K. There have been no material
changes to that information disclosed in our 2021 Form 10-K during the nine
months ended September 30, 2022.

Components of results of operations

We anticipate that our expenses will increase substantially if and as we:



•establish a sales, marketing and distribution infrastructure and scale-up
manufacturing capabilities to potentially commercialize any products for which
we may obtain regulatory approval;

•conduct our ongoing Phase 3 clinical trials for ensifentrine for the maintenance treatment of COPD;

•continue the clinical development of our DPI and pMDI formulations of ensifentrine and research and develop other formulations of or combinations with 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;

•maintain, expand and protect our intellectual property portfolio;



•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; or

•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.


                                       22
--------------------------------------------------------------------------------

Operating expenses

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.

As the Phase 3 ENHANCE program is nearing completion, we expect our research and
development costs to decrease over the next several quarters until we add new
compounds or develop ensifentrine further in 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.

Selling, general and administrative costs

Selling, 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 commercial
operations, prepare for a potential launch and, in the event of successful
regulatory approval, 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/(expense)

Other income/(expense) are driven by interest income and expense, the fair value
movement of the warrant liability until they expired on May 2, 2022, foreign
exchange movements on cash and cash equivalents and taxes receivable, and the
U.K. research and development tax credits.

We 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 us. Credits recorded in the 2021 financial year are expected to be
received in the fourth quarter of 2022.

Taxation



We are subject to corporate taxation in the United States and the United
Kingdom. We have generated losses since inception and have therefore not paid
United Kingdom corporation tax. The income taxes presented in our consolidated
statements of operations and comprehensive loss represents the tax impact from
our operating activities in the United States, which generates taxable income
based on intercompany service arrangements.

United Kingdom losses may be carried forward indefinitely to be offset against
future taxable profits, subject to various utilization criteria and
restrictions. The amount that can be offset each year is limited to £5.0 million
plus an incremental 50% of U.K. taxable profits.

Revenue

Revenue of $40.0 million for the three months ended September 30, 2021 is related to upfront consideration received under the Nuance Agreement. There was no revenue for the three months ended September 30, 2022.

Research and development costs



Research and development costs were $9.8 million for the three months ended
September 30, 2022, compared to $22.6 million for the three months ended
September 30, 2021, a decrease of $12.8 million. This decrease was primarily due
to a $12.5 million decrease in clinical trial and other development costs, as we
progressed to later stages of our Phase 3 ENHANCE program and a $0.6 million
decrease in share-based compensation.

Selling, general and administrative costs



Selling, general and administrative costs were $5.3 million for the three months
ended September 30, 2022, compared to $10.9 million for the three months ended
September 30, 2021, a decrease of $5.6 million, primarily due to a $4.0 million
broker fee relating to the Nuance Agreement in 2021 and a $1.6 million decrease
in share-based compensation.

Other (expense)/income

The research and development tax credit for the three months ended September 30,
2022 was $2.1 million compared to $4.7 million for the three months ended
September 30, 2021, a decrease of $2.6 million. This decrease was primarily due
to a reduction in clinical trial and other development costs, as we progressed
to later stages of our Phase 3 ENHANCE program.

Foreign exchange loss for the three months ended September 30, 2022 was
$3.2 million compared to $0.1 million for the three months ended September 30,
2021, an increase of $3.1 million. This loss was primarily due to a fall in the
value of the British pound against the U.S. dollar affecting pound sterling bank
balances and the R&D tax credit receivable.

                                       24

Net loss

Net loss was $15.6 million for the three months ended September 30, 2022, compared to a net profit of $11.1 million for the three months ended September 30, 2021, because of the factors outlined above.

Revenue

Revenue of $40.0 million for the nine months ended September 30, 2021 is related to upfront consideration received under the Nuance Agreement. There was no revenue for the nine months ended September 30, 2022.

Research and development costs



Research and development costs were $42.4 million for the nine months ended
September 30, 2022, compared to $56.7 million for the nine months ended
September 30, 2021, a decrease of $14.3 million. This decrease was primarily due
to a $11.1 million decrease in clinical trial and other development costs and a
$4.3 million decrease in share-based compensation charges partially offset by a
$1.1 million increase in consultant costs mainly relating to an increase in
clinical trial site audit and NDA filing preparation costs.

Selling, general and administrative costs



Selling, general and administrative costs were $18.3 million for the nine months
ended September 30, 2022 compared to $28.2 million for the nine months ended
September 30, 2021, a decrease of $9.9 million. This decrease was driven
primarily by a $7.3 million decrease in share-based compensation charges and a
$2.0 million decrease due to a $4.0 million broker fee relating to the Nuance
Agreement in 2021 offset by a $2.0 million charge related to the modification of
the Ligand Agreement in 2022.

Other income/(expense)



The research and development tax credit for the nine months ended September 30,
2022 was $8.8 million compared to $10.7 million for the nine months ended
September 30, 2021, a decrease of $1.9 million. This decrease is attributable to
lower qualifying research and development expenditures in the nine months ended
September 30, 2022, compared to the comparative 2021 period.

We recorded no income in the nine months ended September 30, 2022, compared to
an income of $2.2 million in the comparative period relating to the fair value
movements of the warrants. In the nine months ended September 30, 2021, there
was a reduction in liability due to a decrease in the share price in that period
and reduced volatility.

                                       26
--------------------------------------------------------------------------------

Foreign exchange loss for the nine months ended September 30, 2022 was
$6.8 million compared to a gain of $0.1 million gain for the nine months ended
September 30, 2021, an increase of $6.9 million. This loss was primarily due to
a fall in the value of the British pound against the U.S. dollar affecting pound
sterling bank balances and the R&D tax credit receivable.

Net loss

Net loss was $58.3 million for the nine months ended September 30, 2022, compared to $32.3 million for the nine months ended September 30, 2021, because of the factors outlined above.

Cash flows

The following table summarizes our cash flows for the nine months ended September 30, 2022 and 2021 (in thousands):

Operating activities

Net cash used in operating activities was $52.1 million in the nine months ended
September 30, 2022, compared to $15.9 million during the nine months ended
September 30, 2021, an increase of $36.2 million. In 2021, as part of the Nuance
Agreement, we received $25.0 million cash. In 2022, clinical trial and other
development costs decreased as we progressed to later stages of our Phase 3
ENHANCE program.

Financing activities



Net cash provided by financing activities was $138.2 million in the nine months
ended September 30, 2022, compared to $5.2 million net cash used in the nine
months ended September 30, 2021. This increase in net cash received is driven
primarily by the net proceeds from the August 2022 follow-on equity offering.

--------------------------------------------------------------------------------

Liquidity and capital resources



We do not currently have any approved products and have never generated any
revenue from product sales. To date, we have financed our operations primarily
through the issuances of our equity securities, including warrants, from
borrowings under term loan facilities and from upfront payments from the Nuance
Agreement. See "Significant Agreements" and "Indebtedness" for additional
information.

We have incurred recurring losses since inception, including net losses of $58.3
million for the nine months ended September 30, 2022, and $55.6 million for the
year ended December 31, 2021. As of September 30, 2022, we had an accumulated
deficit of $322.4 million. We expect to continue to generate operating losses
for the foreseeable future.

We have no ongoing material financing commitments, such as lines of credit or
guarantees, that are expected to affect our liquidity over the next five years,
other than leases and the Term Loan with Oxford. See "Indebtedness" for details
on the Term Loan.

August 2022 follow-on equity offering



On August 15, 2022, we completed an upsized public offering of 14,260,000 ADSs,
each representing eight of our ordinary shares, nominal value £0.05 per share,
at a price to the public of $10.50 per ADS, which includes the exercise in full
by the underwriters of their option to purchase an additional 1,860,000 ADSs.
The aggregate net proceeds from the offering were approximately $140.1 million
after deducting underwriting discounts and offering expenses.

Open market sale agreement



In March 2021, we entered into 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 to time,
through an "at the market" equity offering program under which Jefferies will
act as sales agent (the "ATM Program").

During the nine months ended September 30, 2022, we sold 80,696 ordinary shares
(equivalent to 10,087 ADSs) under the ATM Program, at an average price of
approximately $0.86 per share (equivalent to $6.86 per ADS), raising aggregate
net proceeds of approximately $0.1 million after deducting issuance costs. As of
September 30, 2022, $99.2 million of ordinary shares, in the form of ADSs,
remained available for sale under the 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, which we refer to as 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
$15.0 million contingent upon achievement of a specific clinical development
milestone and other specified conditions. As of September 30, 2022, we 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 2021 Form
10-K. There have been no material changes to that information disclosed in our
2021 Form 10-K during the nine months ended September 30, 2022.

Subsequent to the quarter end, on October 14, 2022 (the "Effective Date"), we
and Verona Pharma, Inc. ("Verona U.S." and together with us, the "Borrowers")
entered into the Debt Facility with Oxford Finance Luxembourg S.À R.L.
("Oxford") for an aggregate amount of up to $150.0 million (the "Oxford Term
Loan"). The Oxford Term Loan provides for an initial term loan advance in an
aggregate amount of $10.0 million to be funded on the Effective Date (the
"Oxford Term A Loan"), and up to four additional term loan advances in an
aggregate amount of $140.0 million, which are available as described below and
subject to terms of the loan and security agreement ("Loan Agreement"). The
proceeds from the Oxford Term Loan will be used for general corporate and
working capital purposes, and a portion of the proceeds of the Oxford Term A
Loan are being used to repay in full the existing outstanding indebtedness owed
to SVB as discussed in Note 5 - Term Loan. The Oxford Term Loan has a maturity
date of October 1, 2027.

The four additional term loan advances under the Oxford Term Loan consists of a
$10.0 million term loan advance (the "Oxford Term B Loan") which is available at
the option of Company from the Effective Date up to and including March 31,
2023; a $20.0 million term loan advance (the "Oxford Term C Loan") available
during the period commencing on the later of January 1, 2024 and the date on
which we receive positive ENHANCE-1 data in

                                       28
--------------------------------------------------------------------------------

the Phase 3 clinical trial for ensifentrine sufficient to support the submission
of a New Drug Application ("NDA") with the United States Food and Drug
Administration (the "FDA") for ensifentrine through and including March 29,
2024; a $60.0 million term loan advance (the "Oxford Term D Loan") available
during the period commencing on the later of October 1, 2024 and the date on
which we receive final approval from the FDA for our NDA for ensifentrine up to
and including December 31, 2024; and a $50.0 million term loan advance (the
"Oxford Term E Loan") available during the interest-only period at our request
and at Oxford's sole discretion.

Each advance under the Oxford Term Loan accrues interest at a floating per annum
rate equal to (a) the greater of (i) the 1-Month CME Term SOFR reference rate on
the last business day of the month that immediately precedes the month in which
the interest will accrue and (ii) 2.38%, plus (b) 5.50% (the "Basic Rate"). In
no event shall the Basic Rate (x) for the Term A Loan be less than 7.88% and (y)
for each other term loan be less than the Basic Rate on the business day
immediately prior to the funding date of such term loan. The Basic Rate for the
Term A Loan for the period from the Effective Date through and including October
31, 2022 shall be 8.54205% and the Basic Rate for each Term Loan shall not
increase by more than 2.00% above the applicable Basic Rate as of the funding
date of each such term loan. The Oxford Term Loan provides for interest-only
payments on a monthly basis until the payment date immediately preceding
December 1, 2025, if the Term D Loan is not made, and December 1, 2026, if the
Term D Loan is made. Thereafter, amortization payments will be payable monthly
in equal installments of principal plus accrued interest.

Upon repayment, whether at maturity, upon acceleration or by prepayment or
otherwise, we shall make a final payment to the lenders in an amount ranging
from 1.30% to 3.00% of the aggregate principal balance, depending on the
advances received under the Oxford Term Loan. We may prepay the Oxford Term Loan
in full, or in part, in accordance with the terms of the Loan Agreement, which
is subject to a prepayment fee of up to 2.00%, depending on the timing of the
prepayment.

The Oxford Term Loan is secured by a lien on substantially all our assets, other
than intellectual property, but including any rights to payments and proceeds
from the sale, licensing or disposition of intellectual property. We have also
granted Oxford a negative pledge with respect to our intellectual property. The
Loan Agreement contains customary covenants and representations, including but
not limited to financial reporting obligations and limitations on dividends,
dispositions, indebtedness, collateral, investments, distributions, transfers,
mergers or acquisitions, taxes, corporate changes, deposit accounts,
transactions with affiliates and subsidiaries. The Loan Agreement also contains
other customary provisions, such as expense reimbursement, non- disclosure
obligations as well as indemnification rights for the benefit of Oxford.

Funding requirements



We believe that our cash and cash equivalents as of September 30, 2022, together
with, expected cash receipts from U.K. tax credits and additional funding
expected to become available under 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 nebulized
ensifentrine for COPD maintenance treatment in the U.S. Future advances under
the Oxford Term Loan are contingent upon achievement of certain clinical and
regulatory milestones and other specified conditions.

We may require additional capital to commercialize ensifentrine, to continue the
clinical development of our DPI and pMDI formulations of ensifentrine and to
research and develop additional formulations of or with ensifentrine. In
addition, we may seek to initiate or conduct preclinical or clinical studies
with ensifentrine in additional indications or to discover or in-license and
develop additional product candidates. We may 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 capital 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


                                       29
--------------------------------------------------------------------------------

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;



•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 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 revenue, if any, will be derived from sales of products that we
do not expect to be commercially available for several years, if ever.
Accordingly, we may need to obtain substantial additional funds to achieve our
business objectives.
