Overview





We are a clinical-stage biopharmaceutical company focused on providing novel
cell therapies to people with cancer. We are a leader in the development of
engineered T-cell therapies for solid tumors. Our proprietary platform enables
us to identify cancer targets, find and develop cell therapy candidates active
against those targets and produce therapeutic candidates for administration to
patients. Our cell therapies include Specific Peptide Enhanced Affinity Receptor
("SPEAR") T-cells, which use genetically engineered T-cell receptors, and
HLA-independent TCRs (HiTs) that recognize targets independently of the HLA
profile of the tumor cell. Using our SPEAR T-cells, we aim to become the first
company to have a TCR T-cell approved for the treatment of solid tumor
indication.



As the COVID-19 pandemic continues, we remain focused on ensuring the safety of
our workforce and continuing, where possible, to safely treat patients with our
cell therapies. We continue to work with our clinical sites to ensure that
patients are treated as soon as clinical sites are able to do so. Our facilities
in the United States ("U.S.") and the United Kingdom ("U.K.") remain open to
support manufacturing and delivery of our existing cell therapies as well as
research and development of new cell therapies. Further information on risks
related to COVID-19 is provided in the "Information Regarding Forward-Looking
Statements" and "Risk Factors" sections.



We have clinical trials ongoing with our wholly-owned ADP-A2M4, ADP-A2M4CD8, and ADP-A2AFP SPEAR T-cell therapies.

SPEARHEAD-1 Phase 2 Trial with ADP-A2M4: A Phase 2 clinical trial is underway

in synovial sarcoma and myxoid round cell liposarcoma ("MRCLS") indications.

Subject to the successful conclusion of the SPEARHEAD-1 study, which we aim to

fully enroll during the first half of 2021, and approval of a Biologics License

Application by the FDA, we plan to commercially launch ADP-A2M4 in 2022. Orphan

? Drug designation for ADP-A2M4 for the treatment of soft tissue sarcomas has

been granted in the European Union and U.S. together with Regenerative Medicine

Advanced Therapy (RMAT) designation in the U.S. for the treatment of synovial

sarcoma and access to the Priority Medicines ("PRIME") Regulatory Support


   initiative by the European Medicines Agency ("EMA") for ADP-A2M4 for the
   treatment of synovial sarcoma.



SPEARHEAD-2 Phase 2 Trial with ADP-A2M4: A Phase 2 trial combining ADP-A2M4

? with pembrolizumab in ten patients with head and neck cancer is underway at

clinical sites in the United States.

SURPASS Phase 1 Trial with ADP-A2M4CD8: Enrollment is ongoing in a Phase 1

trial for a next generation SPEAR T-cell, ADP-A2M4CD8. We are focussing on the

treatment of patients with lung, gastroesophageal, head and neck and bladder

cancers. This next generation SPEAR T-cell utilizes the same engineered T-cell

receptor as ADP-A2M4, but with the addition of a CD8? homodimer. The addition

of the CD8? homodimer has been shown in vitro to increase cytokine release and

SPEAR T-cell potency. As of July 16, 2020, five patients (one patient with

? MRCLS, two patients with esophagogastric junction ("EGJ") cancers, one patient

with ovarian cancer, and one patient with head and neck cancer) were treated

with ADP-A2M4 CD8 in the dose escalation phase of the trial. One patient with

EGJ cancer had a partial response and has had progression-free survival for

greater than six months. One patient with head and neck cancer also had a

partial response. All other patients have had best overall response of stable

disease ("SD"). We will update on the dose escalation cohorts of the trial at

the Society for Immunotherapy of Cancer ("SITC") conference in November 2020.






Based on the responses seen in the Phase 1 clinical trial using ADP-A2M4 and
these initial responses seen in the SURPASS trial, we are currently planning to
initiate a Phase 2 clinical trial with ADP-A2M4CD8 in gastric, EGJ and
esophageal cancers in the first half of 2021.



ADP-A2M4 Pilot Trial: Our Phase 1 clinical trial of ADP-A2M4 in urothelial,

melanoma, head and neck, ovarian, non-small cell lung, esophageal and gastric,

synovial sarcoma and MRCLS cancers has now completed enrollment. A data update

on the trial was presented at ASCO on May 29, 2020. Clinical responses and

promising durability was reported in patients with synovial sarcoma, with a 50%

response rate (eight partial responses in 16 patients treated) reported,

? including an unconfirmed partial response (44% response rate without inclusion

of unconfirmed partial response). Responses were also reported in head and neck

cancer (one confirmed partial response in three patients treated) and lung

cancer (one confirmed partial response in two patients treated), with evidence

of anti-tumor activity in ovarian cancer and bladder cancer. A radiation

sub-study under the Phase 1 clinical trial also continues to enroll patients

and a partial response in rectal mucosal melanoma was reported in the first


   patient treated.




   ADP-A2AFP Phase 1 Trial: We continue dosing patients in our Phase 1,
   open-label, dose-escalation trial designed to evaluate the safety and

anti-tumor activity of our alpha fetoprotein ("AFP") therapeutic candidate for

the treatment of hepatocellular carcinoma ("HCC"). Data from the trial was

reported at the International Liver Congress in August 2020. Overall four

patients have been treated with approximately five billion or more transduced

· cells (three in Cohort 3 and one in the expansion phase): One patient was

reported to have had a complete response, one patient had SD, and two patients

were reported to have had progressive disease. Five patients were previously

treated in the first two dose cohorts with doses of 100 million and 1 billion

transduced cells, respectively, and all patients had best responses of SD. A

further cohort has also been initiated for patients with tumors other than HCC

that express the AFP antigen. The first patient treated in that cohort was


   assessed by the investigator to have progressive disease.



We have a number of next generation and combination strategies designed to further enhance our SPEAR T-cells in development both internally and in collaboration with third parties. We have two strategic collaboration programs ongoing;

Astellas co-development and co-commercialization: We are collaborating with

Astellas (through its wholly owned subsidiary Universal Cells) in relation to

? up to three targets with the aim of co-developing T-cell therapy candidates

directed to those targets and utilising our allogeneic platform for

"off-the-shelf" cell therapies.

GSK collaboration: We are collaborating with GSK in relation to the

? development, manufacture and commercialization of TCR therapeutic candidates

for up to five programs. The third target program under the Collaboration and


   License Agreement remains ongoing.




We continue to invest and expand our manufacturing and research capabilities to
facilitate a strong future pipeline of cell therapies, to enhance translational
understanding of our cell therapies and to support our target of launching
ADP-A2M4 in 2022, including:

? expanding our ability to manufacture cell therapies at our Navy Yard facility

in the U.S.;

? enhancing commercial resources and activities within the Company ahead of a


   targeted launch date in 2022;

Financial Operations Overview

Revenue

The Company has two contracts with customers: the GSK Collaboration and License Agreement and the Astellas Collaboration Agreement.

The GSK Collaboration Agreement



The GSK Collaboration and License Agreement consists of multiple performance
obligations. GSK nominated its third target under the Collaboration and License
Agreement in 2019, and the Company received $3.2 million following the
nomination of the target, which is being recognized as revenue as development
progresses.

The Astellas Collaboration Agreement



On January 13, 2020, the Company entered into a collaboration agreement with
Astellas. The Company received $50.0 million as an upfront payment in January
2020 after entering into the agreement. Under the agreement the parties will
agree on up to three targets and will co-develop T-cell therapies directed to
those targets pursuant to an agreed research plan. For each target, Astellas
will fund co-development up until completion of a Phase 1 trial for products
directed to such target. In addition, Astellas was also granted the right to
develop, independently of Adaptimmune, allogeneic T-cell therapy candidates
directed to two targets selected by Astellas. Astellas will have sole rights to
develop and commercialize products resulting from these two targets.

The agreement consists of the following performance obligations: (i) research
services and rights granted under the co-exclusive license for each of the three
co-development targets and (ii) the rights granted for each of the two
independent Astellas targets. The revenue allocated to the co-development
targets is recognized as the development of products directed to the targets
progresses up until completion of a Phase 1 trial. The revenue allocated to each
of the research licenses for the targets being independently developed by
Astellas will be recognized when the associated license commences, which is upon
designation of a target by Astellas.

Research and Development Expenses

Research and development expenditures are expensed as incurred. Research and development expenses consist principally of the following:

? salaries for research and development staff and related expenses, including

benefits;

? costs for production of preclinical compounds and drug substances by contract

manufacturers;

? fees and other costs paid to contract research organizations in connection with

additional preclinical testing and the performance of clinical trials;

? costs associated with the development of a process to manufacture and supply

our lentiviral vector and cell therapies for use in clinical trials;

? costs to develop manufacturing capability at our U.S. facility for manufacture

of cell therapies for use in clinical trials;

? costs relating to facilities, materials and equipment used in research and

development;

? costs of acquired or in-licensed research and development which does not have

alternative future use;

? amortization and depreciation of property, plant and equipment and intangible

assets used to develop our cells therapies; and

? share-based compensation expenses;

offset by:

? reimbursable tax and expenditure credits from the U.K. government.




Research and development expenditure is presented net of reimbursements from
reimbursable tax and expenditure credits from the U.K. government. As a company
that carries out extensive research and development activities, we benefit from
the U.K. research and development tax credit regime for small and medium sized
companies ("SME R&D Tax Credit Scheme"), whereby our principal research
subsidiary company, Adaptimmune Limited, is able to surrender the trading losses
that arise from its research and development activities for a payable tax credit
of up to approximately 33.4% of eligible research and development expenditures.
Qualifying expenditures largely comprise employment costs for research staff,
consumables and certain internal overhead costs incurred as part of research
projects for which we do not receive income. Subcontracted research expenditures
are eligible for a cash rebate of up to approximately 21.7%. A large proportion
of costs in relation to our pipeline research, clinical trials management and
manufacturing development activities, all of which are being carried out by
Adaptimmune Limited, are eligible for inclusion within these tax credit cash
rebate claims.

Expenditures incurred in conjunction with our collaboration agreements are not
qualifying expenditures under the SME R&D Tax Credit Scheme but certain of these
expenditures can be reimbursed through the U.K. research and development
expenditure credit scheme (the "RDEC Scheme"). Under the RDEC Scheme tax relief
is given at 12% (up to April 1, 2020) and 13% (after April 1, 2020) of allowable
R&D costs, which may result in a payable tax credit at an effective rate of
approximately 10.3% of qualifying expenditure for the year ended December 31,
2020.

Our research and development expenses may vary substantially from period to
period based on the timing of our research and development activities, which
depends upon the timing of initiation of clinical trials and the rate of
enrollment of patients in clinical trials. The duration, costs, and timing of
clinical trials and development of our cell therapies will depend on a variety
of factors, including:

? the scope, rate of progress, and expense of our ongoing as well as any

additional clinical trials and other research and development activities;

? uncertainties in clinical trial enrollment rates;




                                       21

  Table of Contents

? future clinical trial results;

? significant and changing government regulation;

? the timing and receipt of any regulatory approvals;

? supply and manufacture of lentiviral vector and cell therapies for clinical

trials; and

? an allocation of indirect costs clearly related to research and development.

For further detail please see Part II - Item 1A Risk Factors - Risks Related to the Development of our cell therapies of this Quarterly Report


A change in the outcome of any of these variables may significantly change the
costs and timing associated with the development of that SPEAR T-cell. For
example, if the FDA, or another regulatory authority, requires us to conduct
clinical trials beyond those that we currently anticipate will be required for
regulatory approval, or if we experience significant delays in enrollment in any
of our clinical trials, we could be required to expend significant additional
financial resources and time on the completion of clinical development.

General and Administrative Expenses

Our general and administrative expenses consist principally of:

? salaries for employees other than research and development staff, including

benefits;

? business development expenses, including travel expenses;

? professional fees for auditors, lawyers and other consulting expenses;

? costs of facilities, communication, and office expenses;

? information technology expenses;

? amortization and depreciation of property, plant and equipment and intangible

assets not related to research and development activities; and

? share-based compensation expenses.

Other (Expense) Income, Net



Other (expense) income, net primarily comprises foreign exchange (losses) gains.
We are exposed to foreign exchange rate risk because we currently operate in the
United Kingdom and United States. Our revenue from the GSK Collaboration and
License Agreement is denominated in pounds sterling and is generated by our
U.K.-based subsidiary, which has a pounds sterling functional currency. As a
result, these sales are subject to translation into U.S. dollars when we
consolidate our financial statements. Our expenses are generally denominated in
the currency in which our operations are located, which are the United Kingdom
and United States. However, our U.K.-based subsidiary incurs significant
research and development costs in U.S. dollars and, to a lesser extent, Euros.
Our U.K. subsidiary has an intercompany loan balance in U.S. dollars payable to
the ultimate parent company, Adaptimmune Therapeutics plc. Since July 1, 2019,
the intercompany loan has been considered of a long-term investment nature as
repayment is not planned or anticipated in the foreseeable future. It is
Adaptimmune Therapeutics plc's intent not to request payment of the intercompany
loan for the foreseeable future. The foreign exchange gains or losses arising on
the revaluation of intercompany loans of a long-term investment nature are
reported within other comprehensive loss.

Our results of operations and cash flows will be subject to fluctuations due to
changes in foreign currency exchange rates, which could harm our business in the
future. We seek to minimize this exposure by maintaining currency cash balances
at levels appropriate to

                                       22

  Table of Contents

meet foreseeable expenses in U.S. dollars and pounds sterling. To date, we have
not used hedging contracts to manage exchange rate exposure, although we may do
so in the future.

Taxation

We are subject to corporate taxation in the United Kingdom and the United States. We incur tax losses and tax credit carryforwards in the United Kingdom. No deferred tax assets are recognized on our U.K. losses and tax credit carryforwards because there is currently no indication that we will make sufficient taxable profits to utilize these tax losses and tax credit carryforwards.

We benefit from reimbursable tax credits in the United Kingdom through the SME R&D Tax Credit Scheme as well as the RDEC Scheme which are presented as a deduction to research and development expenditure.


Our subsidiary in the United States has generated taxable profits due to a
Service Agreement between our U.S. and U.K. operating subsidiaries and is
subject to U.S. federal corporate income tax of 21%. Due to its activity in the
United States, and the sourcing of its revenue, the U.S. subsidiary is not
currently subject to any state or local income taxes. The Company also benefits
from the U.S Research Tax Credit and Orphan Drug Credit.

In the future, if we generate taxable income in the United Kingdom, we may
benefit from the United Kingdom's "patent box" regime, which would allow certain
profits attributable to revenues from patented products to be taxed at a rate of
10%. As we have many different patents covering our products, future upfront
fees, milestone fees, product revenues, and royalties may be taxed at this
favorably low tax rate.

U.K. Value Added Tax ("VAT") is charged on all qualifying goods and services by
VAT-registered businesses. An amount of 20% of the value of the goods or
services is added to all relevant sales invoices and is payable to the U.K. tax
authorities. Similarly, VAT paid on purchase invoices paid by Adaptimmune
Limited and Adaptimmune Therapeutics plc is reclaimable from the U.K. tax
authorities.

Critical Accounting Policies and Significant Judgments and Estimates



The preparation of our unaudited condensed consolidated financial statements
requires us to make estimates and assumptions that affect the reported amounts
of assets and liabilities, disclosure of contingent assets and liabilities, and
the revenues and expenses incurred during the reported periods. We base our
estimates on historical experience and on various other factors that we believe
are relevant under the circumstances, the results of which form the basis for
making judgments about the carrying value of assets and liabilities that are not
apparent from other sources. Actual results may differ from these estimates
under different assumptions or conditions. 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 Annual Report.

Allocation of transaction price and determination of costs to complete



Under our revenue generating collaboration agreements, we allocate the aggregate
transaction price to the performance obligations depending on the standalone
selling price of the performance obligations. In determining the best estimate
of the standalone selling price, we considered internal pricing objectives used
in negotiating the contract, together with internal data regarding the cost and
margin of providing services for each deliverable taking into account the
different stage of development of each development program included in the
contract. Assessing the pricing objectives, internal data and the relative
standalone selling price of each performance obligation is highly judgmental and
can have a significant impact on the amount and timing of revenue recognition.

We expect to satisfy the performance obligations relating to the development
activities as development progresses and recognize revenue based on an estimate
of the percentage of completion of the project determined based on the costs
incurred on the project as a percentage of the total expected costs. We consider
that this depicts the progress of the project, where the significant inputs
would be internal project resources and third-party costs. The determination of
the percentage of completion requires management to estimate the
costs-to-complete the project. We make a detailed estimate of the
costs-to-complete, which is re-assessed every reporting period based on the
latest project plan and discussions with project teams. If a change in facts or
circumstances occurs, the estimate will be adjusted and the revenue will be
recognized based on the revised estimate. The difference between the cumulative
revenue recognized based on the previous estimate and the revenue recognized
based on the revised estimate would be recognized as an adjustment to revenue in
the period in which the change in estimate occurs. Identifying the most
appropriate basis on which to recognize revenue and assessing the inputs and

                                       23

  Table of Contents

outputs of the costs-to-complete estimate require significant judgment and may
have a significant impact on the amount and timing of revenue recognition. In
addition, judgment is required to determine the costs-to-complete at each
reporting date, and it is possible that the costs-to-complete in subsequent
periods may differ significantly to those initially anticipated.

Revenue

Revenue increased by $1.0 million to $1.2 million in the three months ended September 30, 2020 compared to $0.2 million for the three months ended September 30, 2019 due to an increase in development activities under our collaboration agreements.

We expect that revenues will increase in future periods as the Company increases development activities on the first target under the Astellas Collaboration Agreement.

Research and Development Expenses

Research and development expenses decreased by 19% to $24.1 million for the three months ended September 30, 2020 from $29.6 million for the three months ended September 30, 2019.

  Table of Contents

The net decrease in our research and development expenses of $5.6 million for
the three months ended September 30, 2020 compared to the same period in 2019
was primarily due to the following:

a decrease of $5.0 million in accrued purchase commitment expenses related to

the supply of the Dynabeads® CD3/CD28 technology. In the three months ended

September 30, 2019, management considered that there was sufficient uncertainty

? surrounding the utility of the Dynabeads, which was dependent upon then current

clinical trial plans, the Company's clinical pipeline, manufacturing methods

and undetermined future projects, to result in the purchase commitment being

recognized in Research and Development expenses in the period

? an increase of $1.1 million in share-based compensation expense due to option

forfeitures in the three months ended September 30, 2019; and

a decrease of $2.5 million in costs for in-process research and development as

? a result of entering into a collaboration agreement relating to the development

of next-generation SPEAR T-cell products with Noile-Immune Biotech, Inc. in the

three months ended September 30, 2019.


Our subcontracted costs for the three months ended September 30, 2020 were $9.6
million, compared to $9.5 million in the same period of 2019. This includes $6.0
million of costs directly associated with our ADP-A2M4, ADP-A2M4CD8, ADP-A2AFP
and ADP-A2M10 SPEAR T-cells and $3.6 million of other development costs.



Our research and development expenses are highly dependent on the phases and
progression of our research projects and will fluctuate depending on the outcome
of ongoing clinical trials. We expect that our research and development expenses
will increase in future periods as we continue to invest in our translational
sciences and other research and development capabilities.

General and Administrative Expenses



General and administrative expenses increased by 21% to $13.0 million for the
three months ended September 30, 2020 from $10.7 million in the same period in
2019. Our general and administrative expenses consist of the following:




                                    Three months ended
                                      September 30,

The net increase in our general and administrative expenses of $2.3 million for
the three months ended September 30, 2020 compared to the same period in 2019
was primarily due an increase of $1.9 million in other corporate costs, which
include professional fees, investment in our IT systems and costs associated
with the buildout of our commercial capabilities.

We expect that our general and administrative expenses will increase in the future as we expand our operations and move towards commercial launch.

Other Expense (Income), Net



Other expense (income), net was an expense of $1.7 million for the three months
ended September 30, 2020 compared to income of $0.3 million for the three months
ended September 30, 2019. Other expense (income), net primarily relates to
unrealized foreign exchange gains and losses on cash, cash equivalents and on
intercompany loans held in U.S. dollars by our U.K. subsidiary, other than those
of a long-term investment nature, where repayment is not planned or anticipated
in the foreseeable.

Revenue

Revenue increased by $2.1 million to $2.5 million in the nine months ended September 30, 2020, compared to $0.4 million for the nine months ended September 30, 2019, due to an increase in development activities under our collaboration agreements.

We expect that revenues will increase in future periods as the Company increases development activities on the first target under the Astellas Collaboration Agreement.

Research and Development Expenses

Research and development expenses decreased by 15% to $65.8 million for the nine months ended September 30, 2020 from $77.1 million for the nine months ended September 30, 2019.

  Table of Contents

The net decrease in our research and development expenses of $11.4 million for
the nine months ended September 30, 2020 compared to the same period in 2019 was
primarily due to the following:

a decrease in salaries, materials, consumables, depreciation of property, plant

? and equipment and other employee-related costs of $2.7 million, primarily due

to lower consumables costs and a reduction in travel costs as a result of

COVID-19 delays;

? a reduction in subcontracted expenditure of $1.3 million, largely driven by

delays brought about by COVID-19;

a decrease of $5.0 million in accrued purchase commitment expenses related to

the supply of the Dynabeads® CD3/CD28 technology. In the nine months ended

September 30, 2019, management considered that there was sufficient uncertainty

? surrounding the utility of the Dynabeads, which was dependent upon then current

clinical trial plans, the Company's clinical pipeline, manufacturing methods

and undetermined future projects, to result in the purchase commitment being

recognized in Research and Development expenses in the period

a decrease of $3.7 million in in-process research and development costs, as a

result of our entering into a collaboration agreement relating to the

development of next-generation SPEAR T-cell products with Alpine Immune

? Sciences, Inc. and Noile-Immune Biotech Inc. in the nine months ended September

30, 2019, offset by work performed by Universal Cells on gene-edited cell lines

under our amended existing agreement with Universal Cells in the nine months

ended September 30, 2020; and

a decrease in reimbursements receivable for research and development tax and

? expenditure credits of $1.2 million, which is driven by the overall reduction

in expenditure in the nine months ended September 30, 2020.




Our subcontracted costs for the nine months ended September 30, 2020 were $24.2
million, compared to $25.6 million in the same period of 2019. This includes
$15.2 million of costs directly associated with our ADP-A2M4, ADP-A2M4CD8,
ADP-A2AFP and ADP-A2M10 SPEAR T-cells and $9.0 million of other development
costs.



Our research and development expenses are highly dependent on the phases and
progression of our research projects and will fluctuate depending on the outcome
of ongoing clinical trials. We expect that our research and development expenses
will increase in future periods as we continue to invest in our translational
sciences and other research and development capabilities.

General and Administrative Expenses


General and administrative expenses were $32.6 million for the nine months ended
September 30, 2020 compared to $32.7 million in the same period in 2019. Our
general and administrative expenses consist of the following:




                                     Nine months ended
                                       September 30,

The net decrease in our general and administrative expenses of $0.1 million for
the nine months ended September 30, 2020 compared to the same period in 2019 was
primarily due to the following:

a decrease of $1.8 million in salaries, depreciation of property, plant and

? equipment and other employee-related costs, which is mainly driven by reduced

travel costs due to COVID-19 and other staff-related costs

an increase of $3.3 million in other corporate costs due to increased

? professional fees, investment in our IT systems and costs associated with the

buildout of our commercial capabilities; and




                                       27

  Table of Contents

? a decrease of $1.3 million in share-based compensation expense due to option

forfeitures.

We expect that our general and administrative expenses will increase in the future as we expand our operations and move towards commercial launch.

Other Expense, Net


Other expense, net was $1.5 million for the nine months ended September 30, 2020
compared to $0.6 million for the nine months ended September 30, 2019. Other
expense, net primarily relates to unrealized foreign exchange gains and losses
on cash, cash equivalents and on intercompany loans held in U.S. dollars by our
U.K. subsidiary, other than those of a long-term investment nature, where
repayment is not planned or anticipated in the foreseeable. From July 1, 2019,
the intercompany loan between the parent company, Adaptimmune Therapeutics Plc
and its subsidiary, Adaptimmune Limited, has been considered of a long-term
investment nature as repayment is not planned or anticipated in the foreseeable
future. It is Adaptimmune Therapeutics plc's intent not to request payment of
the intercompany loan for the foreseeable future. The foreign exchange gains or
losses arising on the revaluation of intercompany loans of a long-term
investment nature are reported within other comprehensive loss.

Income Taxes

Income taxes decreased to a charge of $110,000 for the nine months ended September 30, 2020 from a charge of $154,000 for the nine months ended September 30, 2019. Income taxes arise in the United States due to our U.S. subsidiary generating taxable profits. We incur losses in the United Kingdom.

Liquidity and Capital Resources

Sources of Funds



Since our inception, we have incurred significant net losses and negative cash
flows from operations. We financed our operations primarily through sales of
equity securities, cash receipts under our collaboration arrangements and
research and development tax and expenditure credits. From inception through to
September 30, 2020, we have raised:

$853.8 million, net of issuance costs, through the issuance of shares,

? including $90.5 million raised through a public offering in January and

February 2020 and $243.8 million through a public offering in June 2020;

? $201.6 million through collaborative arrangements with GSK and Astellas; and

? $59.2 million in the form of reimbursable U.K. research and development tax

credits and receipts from the U.K. RDEC Scheme.




We use a non-GAAP measure, Total Liquidity, which is defined as the total of
cash and cash equivalents and marketable securities, to evaluate the funds
available to us in the near-term. A description of Total Liquidity and
reconciliation to cash and cash equivalents, the most directly comparable U.S.
GAAP measure, are provided below under "Non-GAAP measures".

As of September 30, 2020, we had cash and cash equivalents of $78.5 million and
Total Liquidity of $399.9 million. We regularly assess Total Liquidity against
our activities and make decisions regarding prioritization of those activities
and deployment of Total Liquidity. We believe that our Total Liquidity will be
sufficient to fund our operations, based upon our currently anticipated research
and development activities, planned capital spending, and planned
commercialization costs into 2022. This belief is based on estimates that are
subject to risks and uncertainties and may change if actual results differ

from
management's estimates.

Operating Activities

Net cash used in operating activities was $24.4 million for the nine months
ended September 30, 2020 compared to $100.0 million for the nine months ended
September 30, 2019. The net cash used in operating activities has been
significantly reduced by the receipt of the $50.0 million upfront payment from
Astellas in January 2020 and a reduction in operating expenditure due to
COVID-19.

Net cash used in operating activities of $24.4 million for the nine months ended
September 30, 2020 comprised a net loss of $93.5 million, offset by non-cash
items of $14.9 million and a net cash inflow of $54.2 million from changes in
operating assets and liabilities. The non-cash items consisted primarily of
depreciation expense on plant and equipment of $5.2 million, share-based
compensation expense of $7.4 million, amortization of $0.7 million and other
items of $2.8 million. This was partially offset by unrealized foreign exchange
gains of $1.1 million.

Investing Activities

Net cash used in investing activities was $286.5 million for the nine months
ended September 30, 2020 compared to net cash provided by investing activities
of $71.3 million for the nine months ended September 30, 2019. The net cash
(used in) provided by investing activities for the respective periods consisted
of:

? purchases of property and equipment of $1.2 million and $1.4 million for the

nine months ended September 30, 2020 and 2019, respectively;

purchases of intangible assets of $0.5 million and $1.0 million primarily

? relating to development of internal-use software for the nine months ended

September 30, 2020 and 2019, respectively; and

cash outflows from investment in marketable securities of $363.8 million and

$19.1 million for the nine months ended September 30, 2020 and 2019,

? respectively, and cash inflows from maturity or redemption of marketable

securities of $78.9 million and $92.8 million for the nine months ended

September 30, 2020 and 2019, respectively.




The Company invests surplus cash and cash equivalents in marketable securities.
In the nine months ended September 30, 2019, the investments in marketable
securities were reduced to fund the Company's ongoing operations. In the nine
months ended September 30, 2020, the Company increased its investments in
marketable securities with proceeds from its public offerings.

Financing Activities



Net cash provided by financing activities was $339.9 million and $0.4 million
for the nine months ended September 30, 2020 and 2019, respectively. For the
nine months ended September 30, 2020, the net cash provided by financing
activities consisted of net proceeds from public offerings of $334.4 million,
and proceeds from share option exercises of $5.5 million. The net cash provided
by financing activities in the nine months ended September 30, 2019 consisted of
proceeds from share option exercises.

Non-GAAP Measures

Total Liquidity (a non-GAAP financial measure)



Total Liquidity (a non-GAAP financial measure) is the total of cash and cash
equivalents and marketable securities. Each of these components appears in the
condensed consolidated balance sheet. The U.S. GAAP financial measure most
directly comparable to Total Liquidity is cash and cash equivalents as reported
in the condensed consolidated financial statements, which reconciles to Total
Liquidity as follows (in thousands):


                                                                September 30,       December 31,

We believe that the presentation of Total Liquidity provides useful information
to investors because management reviews Total Liquidity as part of its
management of overall liquidity, financial flexibility, capital structure and
leverage. The definition of Total Liquidity includes investments, which are
highly-liquid and available to use in our current operations, such as marketable
securities.

Off-Balance Sheet Arrangements


We did not have during the periods presented, and we do not currently have, any
off-balance sheet arrangements, as defined in the rules and regulations of
