COVID-19 Business Update

We are closely monitoring developments related to COVID-19, which was declared a pandemic by the World Health Organization on March 11, 2020. In response to this global pandemic, we have concentrated our efforts to remain focused on the health and safety of our employees and patients, while maintaining business continuity and honoring our commitment to deliver life-changing treatments for people battling devastating diseases.

We implemented business continuity plans in March 2020 designed to address the impact of COVID-19 on our business, which continue to evolve with the rapid evolution of the pandemic. Effective March 12, 2020, we implemented measures to mitigate the spread of COVID-19 and contribute to the ongoing public health effort to reduce the spread of the virus. We formed a COVID-19 Response Team to maintain business continuity while safeguarding employee and patient health. We also mandated a work-from-home policy for most employees and set up additional processes to work from home effectively, including measures to bolster our cybersecurity. Our COVID-19 Response Team continues to assess, evaluate and evolve our ongoing business continuity plans and our COVID-19 policies and guidance.

Our manufacturing operations and lab-based activities continue with social-distancing and updated protocols for accessing our facilities. As a biopharmaceutical research and development company, we are deemed to provide essential services under the “stay at home” advisory that was issued by the Governor of Massachusetts on March 23, 2020. While we continue to conduct R&D activities, including our ongoing clinical trials, the COVID-19 pandemic has impacted, and may continue to impact, certain of our early-stage discovery efforts and clinical trials. We are working with our clinical investigators, R&D vendors and supply chain vendors to continually assess and take steps to mitigate the potential impact of COVID-19 on our manufacturing operations and R&D activities.

We will continue to closely monitor the COVID-19 situation as we evolve our business continuity plans. Given the global economic slowdown and the other risks and uncertainties associated with COVID-19, our business, financial condition, results of operations, and prospects could be materially adversely affected. For additional information, see “Item 1A. Risk Factors” of this Quarterly Report on Form 10-Q.

Overview

We are a clinical-stage genetic medicines company committed to delivering life-changing treatments for people battling devastating diseases. Using PRISM, our proprietary discovery and drug development platform that enables the precise design, optimization and production of novel stereopure oligonucleotides, we aspire to develop best in class medicines for genetically defined diseases with a high degree of unmet need.

Nucleic acid therapeutics, including oligonucleotides, are a growing and innovative class of drugs comprised of a sequence of nucleotides that are linked together by a backbone of chemical bonds. We are initially developing oligonucleotides that target the ribonucleic acid (“RNA”) to either reduce the expression of disease-promoting proteins or transform the production of dysfunctional mutant proteins into the production of functional proteins. RNA is a critical molecule that can adopt complex three-dimensional structures and affect various cellular functions. By intervening at the RNA level, we have the potential to address diseases that have historically been difficult to treat with small molecules or biologics. The mechanisms that we are currently using to target RNA with our oligonucleotides include RNase H-mediated RNA degradation, Ago2-mediated RNA interference (“RNAi”), exon-skipping, and ADAR (adenosine deaminases acting on RNA)-mediated RNA editing. Oligonucleotides have additional advantages as a therapeutic class including the ability to target multiple tissue types, often without the need for a delivery vehicle, and the ability to modulate the frequency of dosing to ensure broad distribution within tissues. Oligonucleotides also have well-established manufacturing processes and validated test methods based on decades of improvements.

The oligonucleotides we are developing with PRISM are stereopure. A stereopure oligonucleotide is comprised of molecules with atoms precisely arranged in three-dimensional orientations at each linkage. We believe that controlling the stereochemistry of each backbone position will optimize the pharmacological profile of our oligonucleotides by maximizing the potential therapeutic benefit while minimizing the potential for side effects and safety risks. The stereopure oligonucleotides we are developing differ from the mixture-based oligonucleotides currently on the market or in development by others. Our preclinical studies have demonstrated that our stereopure oligonucleotides may achieve superior pharmacological properties compared with mixture-based oligonucleotides. Through our work in developing stereopure oligonucleotides, we have created and continue to evolve PRISM, our proprietary discovery and drug development platform.

PRISM enables us to target genetically defined diseases with stereopure oligonucleotides across multiple therapeutic modalities. PRISM combines our unique ability to construct stereopure oligonucleotides with a deep understanding of how the interplay among oligonucleotide sequence, chemistry and backbone stereochemistry impacts key pharmacological properties. By exploring these interactions through iterative analysis of in vitro and in vivo outcomes and artificial intelligence-driven predictive modeling, we continue to define design principles that we deploy across programs to rapidly develop and manufacture clinical candidates that meet pre-defined product profiles.

Our lead clinical development programs are focused in genetic diseases within neurology. Our most advanced stereopure therapeutic candidates in development, WVE-120101 and WVE-120102, are designed to selectively target mutant huntingtin (“mHTT”) and spare wild-type, or healthy, huntingtin (“wtHTT”) for the treatment of Huntington’s disease (“HD”). WVE-120101 and WVE-120102 are currently being studied in two Phase 1b/2a clinical trials, PRECISION-HD1 and PRECISION-HD2. Our next neurology programs approaching clinical development include our mHTT SNP3 program for the treatment of HD and our C9orf72 program for the treatment of amyotrophic lateral sclerosis (“ALS”) and frontotemporal dementia (“FTD”). We are also pursuing additional CNS programs in collaboration with Takeda Pharmaceutical Company Limited (“Takeda”), including spinocerebellar ataxia 3 (“SCA3”). Outside of neurology, we are advancing discovery research in ophthalmologic disorders, specifically inherited retinal diseases, in hepatic diseases, and in ADAR-mediated RNA-editing applications. In further support of our pipeline, we continue to invest in PRISM to potentially develop the next generation of stereopure oligonucleotides. We have also established and continue to enhance our internal current good manufacturing practices (“cGMP”) manufacturing capabilities to increase control and visibility of our drug substance supply chain.

18

Our Current Programs

Additional details regarding our programs are set forth below.

Neurology

Huntington’s Disease (“HD”): HD is a rare hereditary neurodegenerative disease that results in early death and for which there is no cure. HD is caused by a mutation (i.e., an expanded CAG triplet repeat) in the HTT gene, which results in production of mutant HTT (“mHTT”) protein. In HD patients, there is a progressive loss of neurons in the brain leading to cognitive, psychiatric and motor disabilities. HD patients still possess wild-type (healthy) HTT (“wtHTT”) protein, which is important for neuronal function and there is increasing evidence that wtHTT may be neuroprotective in an adult brain. Additionally, a dominant gain of function in mHTT protein and a concurrent loss of function of wtHTT protein may be important components of the pathophysiology of HD. Accordingly, suppression of wtHTT may have detrimental long-term consequences. Absence of wtHTT protein has been shown to be embryonically lethal in mice. In October 2019, at our Analyst and Investor Research Day, key opinion leaders in HD research presented data suggesting that wtHTT is neuroprotective in an adult brain; transport of key neurotrophic factors such as brain-derived neurotrophic factor (“BDNF”) are regulated by wtHTT levels; and HD may be caused by a dominant gain of function in mutant HTT and a loss of function of wtHTT protein. Further, the relative proportion of wtHTT to mHTT is critical based on evidence that suggests an increased amount of wtHTT relative to mHTT may result in slower disease progression (measured by age-at-onset). Also, HD patients that lack wtHTT all together have significantly more severe disease, as measured by disease progression after symptom onset.

Our HD Portfolio: In HD, we are currently advancing two clinical programs and one preclinical program. WVE-120101 and WVE-120102 are our clinical programs, where each is a distinct stereopure antisense oligonucleotide designed to selectively target a single nucleotide polymorphism (“SNP”) associated with the disease-causing mutant huntingtin (mHTT) mRNA transcript within the HTT gene: rs362307 (“mHTT SNP1”) and rs362331 (“mHTT SNP2”), respectively. Our third program in HD, which we refer to as our “mHTT SNP3” program, is also a stereopure antisense oligonucleotide designed to selectively target an undisclosed SNP on the mHTT mRNA transcript. Our mHTT SNP3 program is currently in the preclinical stage. Approximately 50% of the HD population carries SNP1 or SNP2 and, with overlap, up to 70% of the HD population carries either SNP1, SNP2 or both. Approximately 40% of the HD population carries SNP3 and, with overlap, up to 80% of the HD population carries at least one of SNP1, SNP2 and/or SNP3. Targeting mRNA transcript with these SNPs allows us to lower the mutant allele transcript, while leaving the healthy transcript relatively intact. The healthy transcript is required to produce healthy HTT protein which is important for neuronal function. We commonly refer to this method (or approach) as “allele selective targeting.” SNPs are naturally occurring variations within a given genetic sequence and in certain instances can be used to distinguish between two related copies of a gene where only one is associated with the expression of a disease-causing protein. Our allele selective approach may also enable us to address the pre-manifest, or asymptomatic, HD patient population in the future. We have shown that by targeting mHTT SNP1 and mHTT SNP2 in preclinical in vitro studies, the production of disease-causing proteins associated with HD can be selectively reduced. In addition, we have shown that by targeting mHTT SNP3 in preclinical in vitro studies, our SNP3 compounds selectively reduce the expression of the mutant HTT.

19

Phase 1b/2a Clinical Trials: PRECISION-HD is a global clinical program consisting of the PRECISION-HD1 and PRECISION-HD2 clinical trials. PRECISION-HD1 and PRECISION-HD2 are two parallel, multicenter, double-blind, randomized, placebo-controlled Phase 1b/2a clinical trials evaluating WVE-120101 and WVE-120102, respectively, administered intrathecally, consisting of single-ascending dose and multiple-ascending dose portions. The primary objective of these two trials is to assess the safety and tolerability of intrathecal doses of WVE-120101 and WVE-120102, respectively, in early manifest HD patients. Additional objectives include measurement of total HTT protein and mutant HTT protein, and exploratory pharmacokinetic, pharmacodynamic, clinical and MRI endpoints. Each trial is designed with five multi-dose cohorts (2, 4, 8, 16, and 32 mg), each with 12 patients that have Stage I or Stage II HD, ages 25-65, who have screened positively for the presence of SNP1 or SNP2. Outside of the United States, we are conducting both the single-ascending dose and multiple-ascending dose portions of the PRECISION-HD1 and PRECISION-HD2 trials. In the United States, we received approvals to proceed with the single-dose portions of both trials. However, the FDA indicated to us that we cannot progress to the multiple-ascending dose portions of these trials in the United States unless we conduct an additional preclinical study and present the resulting data to the FDA for its review. For the single-dose portion of the PRECISION-HD1 trial in the United States, escalation to our highest proposed doses is subject to the FDA’s review and approval of additional monitoring plans. WVE-120101 and WVE-120102 have been granted orphan drug designation for the treatment of HD by the FDA. In response to the global COVID-19 pandemic, we have taken, and will continue to take, actions to minimize disruptions to our PRECISION-HD clinical trials, including, among other actions, more frequent communications with our trial sites to monitor the impact of the evolving pandemic. If global restrictions continue or worsen, the ability to evaluate patients in both of the PRECISION-HD trials as planned may be impacted.

PRECISION-HD2 trial: In December 2019, we announced initial clinical data from our ongoing PRECISION-HD2 trial. In an analysis comparing all patients treated with multiple intrathecal doses of WVE-120102 to placebo, a statistically significant reduction of 12.4% (p<0.05) in mHTT protein was observed in cerebrospinal fluid (“CSF”). An analysis to assess a dose response across treatment groups (2, 4, 8, or 16 mg) suggested a statistically significant response in mHTT reduction at the highest doses tested (p=0.03). WVE-120102 was generally safe and well tolerated across all cohorts. These topline data supported the addition of higher dose cohorts, and we initiated the 32 mg cohort in January 2020. We expect to deliver clinical data from the 32 mg cohort in the second half of 2020.

PRECISION-HD1 trial: We initiated the 32 mg cohort of the PRECISION-HD1 trial in March 2020. We expect to deliver topline clinical data from the five multi-dose cohorts (2, 4, 8, 16, 32 mg) of the PRECISION-HD1 trial in the second half of 2020.

Open-label Extensions of PRECISION-HD1 and PRECISION-HD2: In October 2019, we initiated an OLE of the PRECISION-HD2 trial outside of the United States for patients who participated in that trial. In February 2020, we initiated an OLE of the PRECISION-HD1 trial outside of the United States for patients who participated in that trial.

mHTT SNP3 Program in HD: We expect to initiate clinical development of our mHTT SNP3 program in the second half of 2020.

ALS and FTD: In amyotrophic lateral sclerosis (“ALS”) and frontotemporal dementia (“FTD”), we are advancing our C9orfF72 program, which is designed to selectively target the transcripts containing the hexanucleotide repeat expansion (G4C2) in the C9orf72 gene. Our C9orf72 program is designed to minimize the impact on normal C9orf72 protein in patients, thereby reducing potential on-target risk. The G4C2 expansion in the C9orf72 gene is the most common cause of familial ALS and FTD and is a strong genetic risk factor for non-inherited (sporadic) forms of ALS and FTD. We expect to initiate clinical development of our C9orf72 program in the second half of 2020.

SCA3: In spinocerebellar ataxia 3 (“SCA3”), we are continuing to advance our program targeting ATXN3. SCA3 is a rare, hereditary (autosomal dominant), progressive, neurodegenerative disorder that is caused by a CAG-repeat expansion in the ATXN3 gene.

Additional CNS Disorders: We are collaborating with Takeda to advance genetically defined targets for the treatment of other CNS disorders, including Alzheimer’s disease, Parkinson’s disease, and others. Under the terms of the agreement, we may collaborate with Takeda on up to six preclinical programs at any one time, during a four-year term. Takeda is entitled to exclusively license multiple preclinical programs from us during the term.

Ophthalmology

We are designing and advancing stereopure oligonucleotides for the potential treatment of rare, inherited eye diseases. Our preclinical data demonstrate that a single intravitreal injection of stereopure oligonucleotide in the eye of non-human primates (“NHPs”) resulted in greater than 95% knockdown of a target RNA in the retina for at least four months. Based on these data, we are working to design candidates that could achieve a therapeutic effect with only two doses per year. We are focused on advancing two preclinical programs: Usher syndrome type 2A (“USH2A”) and retinitis pigmentosa due to a P23H mutation in the RHO gene (“RhoP23H”). In October 2019, we presented in vitro and ex vivo preclinical data on our USH2A program, which is designed to promote USH2A exon 13 skipping, and we presented in vitro data on our RhoP23H program, which is designed to selectively silence RhoP23H transcripts.

20

Hepatic

In May 2020, we announced the first in vivo data from our novel RNA-editing platform, which demonstrated successful RNA editing of ACTB (Beta-actin) mRNA in NHPs via endogenous ADARs using stereopure GalNAc-conjugated oligonucleotides. In this ongoing proof-of-concept study, our oligonucleotides demonstrated up to 50% A to I (G) editing of ACTB mRNA in the liver of NHPs two-days post-last dose. To our knowledge, these are the first publicly available data that demonstrate successful RNA editing in vivo in NHPs.

We recently concluded our collaboration with Pfizer Inc. to advance genetically defined targets for the treatment of metabolic diseases. Through our work in the collaboration, we have incorporated valuable learnings and technology advancements into PRISM, where we have leveraged our new understanding of GalNAc conjugations to design novel RNA-editing oligonucleotides.

Recent Developments

On February 6, 2020, we implemented a plan to reduce operating costs and better align our workforce with the needs of our business following our December 16, 2019 announcement of our decision to discontinue the suvodirsen program for patients with DMD and to cease development of our other DMD programs. Under this cost reduction plan, we reduced our workforce by approximately 22%. The reduction in workforce was completed in February 2020.

Financial Operations Overview

We have never been profitable, and since our inception, we have incurred significant operating losses. Our net loss was $47.5 million and $44.2 million in the three months ended March 31, 2020 and 2019, respectively. As of March 31, 2020 and December 31, 2019, we had an accumulated deficit of $580.9 million and $533.4 million, respectively. We expect to incur significant expenses and operating losses for the foreseeable future.

Revenue

We have not generated any product revenue since our inception and do not expect to generate any revenue from the sale of products for the foreseeable future. Our revenue during the three months ended March 31, 2020 and 2019 represents revenue earned under our two revenue-generating collaboration agreements: the Pfizer Collaboration Agreement (as defined in Note 5 in the notes to the unaudited consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q (“Note 5”)), which was entered into in May 2016, and the Takeda Collaboration Agreement (as defined in Note 5), which became effective in April 2018.

Operating Expenses

Our operating expenses since inception have consisted primarily of research and development costs and general and administrative costs.

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for our research activities, including our discovery efforts, and the development of our product candidates, which include:

We recognize research and development costs as incurred. We recognize external development costs based on an evaluation of the progress to completion of specific tasks using information provided to us by our vendors. Payments for these activities are based on

21

the terms of the individual agreements, which may differ from the pattern of costs incurred, and are reflected in our financial statements as prepaid or accrued expenses.

Our primary research and development focus since inception has been the development of our proprietary discovery and drug development platform, PRISM. We are using PRISM to design, develop and commercialize a broad pipeline of nucleic acid therapeutic candidates.

Our research and development expenses consist primarily of expenses related to our CROs, CMOs, consultants, other external vendors and fees paid to global regulatory agencies to conduct our clinical trials, in addition to compensation-related expenses, internal manufacturing expenses, facility-related expenses and other general operating expenses. These expenses are incurred in connection with research and development efforts and our preclinical studies and clinical trials. We track certain external expenses on a program-by-program basis. However, we do not allocate compensation-related expenses, internal manufacturing expenses, equipment repairs and maintenance expense, facility-related expenses or other operating expenses to specific programs. These expenses, which are not allocated on a program-by-program basis, are included in the “PRISM and other research and development expenses” category along with other external expenses related to our discovery and development programs, as well as platform development and identification of potential drug discovery candidates.

The table below summarizes our research and development expenses incurred for the three months ended March 31, 2020 and 2019:

Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect to continue to incur significant research and development expenses in the foreseeable future as we continue to manage our existing clinical trials, initiate additional clinical trials for certain product candidates, pursue later stages of clinical development for certain product candidates, maintain our manufacturing capabilities and continue to discover and develop additional product candidates in multiple therapeutic areas.

General and Administrative Expenses

General and administrative expenses consist primarily of compensation-related expenses, including salaries, bonuses, share-based compensation and other related benefits costs for personnel in our executive, finance, corporate, legal and administrative functions, as well as compensation-related expenses for our board of directors. General and administrative expenses also include legal fees; expenses associated with being a public company; professional fees for accounting, auditing, tax and consulting services; insurance costs; travel expenses; other operating costs; and facility-related expenses.

Other Income, Net

Other income, net consists primarily of refundable tax credits from tax authorities and dividend income earned on cash and cash equivalents balances. We recognize refundable tax credits when there is reasonable assurance that we will comply with the requirements of the refundable tax credit and that the refundable tax credit will be received.

Income Taxes

We are a Singapore multi-national company subject to taxation in the United States and various other jurisdictions.

22

Critical Accounting Policies and Significant Judgments and Estimates

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States. The preparation of our financial statements and related disclosures requires us to make estimates and assumptions that affect the reported amount of assets, liabilities, revenue, costs and expenses and related disclosures.

Our significant accounting policies, judgments and estimates are described in Note 2 in the notes to the audited consolidated financial statements included in the 2019 Annual Report on Form 10-K, as well as in Note 2 in the notes to the unaudited consolidated financial statements included in this Quarterly Report on Form 10-Q. We believe that our revenue recognition policy, particularly (a) assessing the number of performance obligations; (b) determining the transaction price; (c) allocating the transaction price to the performance obligations in the contract; and (d) determining the pattern over which performance obligations are satisfied, including estimates to complete performance obligations, and the assumptions and estimates used in our analysis of contracts with CROs and CMOs to estimate the contract expense, involve a greater degree of judgment, and therefore we consider them to be our critical accounting policies. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions and conditions.

Results of Operations

Comparison of the three months ended March 31, 2020 and 2019

Revenue

Revenue of approximately $4.2 million and $3.0 million was earned under the Pfizer Collaboration Agreement and the Takeda Collaboration Agreement for the three months ended March 31, 2020 and 2019, respectively. The $1.1 million increase in revenue is due to an increase in research and development services under the Pfizer Collaboration Agreement and the Takeda Collaboration Agreement.

Research and development expenses were $41.2 million for the three months ended March 31, 2020, compared to $40.1 million for the three months ended March 31, 2019. The increase of approximately $1.0 million was due to the following:

General and Administrative Expenses

General and administrative expenses were $13.0 million for the three months ended March 31, 2020, as compared to $10.9 million for the three months ended March 31, 2019. The increase of $2.1 million was mainly driven by compensation-related costs, including employee severance, benefits and related termination costs due to the February 2020 reduction in workforce.

Other Income, Net

Other income, net for the three months ended March 31, 2020 and 2019 was $2.5 million and $3.8 million, respectively. The decrease of $1.3 million in other income, net is primarily due to decreased dividend income earned on cash and cash equivalents.

Income Tax Provision

During the three months ended March 31, 2020 and 2019, we recorded no income tax provision. We maintained a full valuation allowance for the three months ended March 31, 2020 and 2019 in all jurisdictions due to uncertainty regarding future taxable income.

Liquidity and Capital Resources

Since our inception, we have not generated any product revenue and have incurred recurring net losses. To date, we have primarily funded our operations through private placements of debt and equity securities, public offerings of our ordinary shares and collaborations with third parties. Through March 31, 2020, we have received an aggregate of approximately $655.0 million in net proceeds from these transactions. We received $89.3 million in net proceeds from private placements of our debt and equity securities, $100.4 million in net proceeds from our initial public offering, $40.0 million under the Pfizer Agreements (as defined in Note 5), including $10.0 million as an upfront payment under the Pfizer Collaboration Agreement and $30.0 million in the form of an equity investment, $93.5 million in net proceeds from our April 2017 follow-on underwritten public offering, $170.0 million in upfront payments under the Takeda Agreements (as defined in Note 5), including $110.0 million as an upfront payment under the Takeda Collaboration Agreement (as defined in Note 5) and $60.0 million in the form of an equity investment, and $161.8 million in net proceeds from our January 2019 follow-on underwritten public offering.

As of March 31, 2020, we had cash and cash equivalents totaling $120.9 million, an accumulated deficit of $580.9 million and restricted cash of $3.6 million for our leased premises in Cambridge, Massachusetts and Lexington, Massachusetts.

We expect that our existing cash and cash equivalents will be sufficient to fund our operations for at least the next twelve months. We have based this expectation on assumptions that may prove to be incorrect, and we may use our available capital resources sooner than we currently expect. In addition, we may elect to raise additional funds before we need them if the conditions for raising capital are favorable due to market conditions or strategic considerations, even if we expect we have sufficient funds for our current or future operating plans.

Until we can generate significant revenue from product sales, if ever, we expect to continue to finance our operations through a combination of public or private equity or debt financings or other sources, which may include collaborations with third parties.

In May 2019, we filed a shelf registration statement on Form S-3ASR with the SEC pursuant to which we registered for sale an indeterminate amount of any combination of our ordinary shares, debt securities, warrants, rights and/or units from time to time and at prices and on terms that we may determine. Our shelf registration statement on Form S-3ASR also includes a prospectus covering up to an aggregate of $250.0 million in ordinary shares that we may issue and sell from time to time, through Jefferies LLC acting as our sales agent, pursuant to the open market sales agreement that we entered into with Jefferies LLC in May 2019, as amended in March 2020, for our “at-the-market” equity program. Since we no longer qualified as a “well-known seasoned issuer” at the time of the filing of our 2019 Annual Report on Form 10-K, we amended the shelf registration statement to register for sale up to $500.0 million of any

24

combination of our ordinary shares, debt securities, warrants, rights and/or units from time to time and at prices and on terms that we may determine, including the up to $250.0 million in ordinary shares that we may issue and sell from time to time pursuant to our “at-the-market” equity program. During the three months ended March 31, 2020, we sold approximately 60,000 ordinary shares under our at-the market equity program for aggregate net proceeds of approximately $0.6 million. As of this filing on May 11, 2020, we have sold an aggregate of approximately 357,000 ordinary shares resulting in aggregate net proceeds of approximately $3.4 million under our at-the-market equity program, thereby leaving approximately $246.6 million in ordinary shares available for sale thereunder.

Adequate additional financing may not be available to us on acceptable terms, or at all. Raising capital in the current economic environment, particularly in light of the economic downturn and ongoing uncertainty related to the COVID-19 pandemic, may be challenging. Our inability to raise capital as and when needed would have a negative impact on our financial condition and our ability to pursue our business strategy. We will need to generate significant revenue to achieve profitability, and we may never do so.

Cash Flows

The following table summarizes our cash flow activity:

Operating Activities

During the three months ended March 31, 2020, operating activities used $26.3 million of cash, primarily due to our net loss of $47.5 million, offset by a $20.0 million decrease in accounts receivable.

During the three months ended March 31, 2019, operating activities used approximately $50.4 million of cash, primarily due to our net loss of $44.2 million and changes in our operating assets and liabilities of $12.7 million, offset by non-cash charges of $6.5 million. The largest changes in operating assets and liabilities were a decrease of $6.5 million in accrued expenses and other current liabilities, as well as a decrease of $3.0 million in deferred revenue. The non-cash charges for the three months ended March 31, 2019 were mainly related to share-based compensation expense of $4.3 million and depreciation expense of $1.8 million.

Investing Activities

During the three months ended March 31, 2020, investing activities used $0.6 million of cash, related to purchases of property and equipment.

During the three months ended March 31, 2019, investing activities used $0.5 million of cash, related to purchases of property and equipment.

Financing Activities

During the three months ended March 31, 2020, net cash provided by financing activities was $0.6 million, which was primarily due to the net proceeds from sales of ordinary shares under our at-the-market equity program.

During the three months ended March 31, 2019, net cash provided by financing activities was $163.6 million, which was primarily due to the $162.1 million in net proceeds from our underwritten public offering of ordinary shares in January 2019 and approximately $1.5 million in proceeds from the exercise of share options.

Funding Requirements

We expect to continue to incur significant expenses in connection with our ongoing research and development activities and our internal cGMP manufacturing activities. Furthermore, we anticipate that our expenses will continue to vary if and as we:

We may experience delays or encounter issues with any of the above, including but not limited to failed studies, complex results, safety issues or other regulatory challenges.

Because of the numerous risks and uncertainties associated with the development of drug candidates and because the extent to which we may enter into collaborations with third parties for development of product candidates is unknown, we are unable to estimate the amounts of future capital outlays and operating expenses associated with completing the research and development for our therapeutic programs. Our future capital requirements for our therapeutic programs will depend on many factors, including:

Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our product revenue, if any, will be derived from sales of products that we do not expect to be commercially available for many years, if ever. Accordingly, we will need to obtain substantial additional funds to achieve our business objectives.

Adequate additional funds may not be available to us on acceptable terms when we need them, or at all. We do not currently have any committed external source of funds, except for committed funds and possible future payments from Takeda under the Takeda Collaboration Agreement. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our existing shareholders will be diluted, and the terms may include liquidation or other preferences that adversely affect the rights of our shareholders. Additional debt financing and 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

26

capital expenditures or declaring dividends and may require the issuance of warrants, which could potentially dilute our shareholders’ 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.

Contractual Obligations and Commitments

There have been no material changes to our contractual obligations and commitments set forth under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Contractual Obligations and Commitments” in our 2019 Annual Report on Form 10-K.

Off-Balance Sheet Arrangements

We had no off-balance sheet arrangements (as that term is defined in Item 303(a)(4)(ii) of Regulation S-K) as of March 31, 2020 that have, or are reasonably likely to have, a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Recently Issued Accounting Pronouncements

The recently issued accounting pronouncements described in the Company’s audited financial statements as of and for the year ended December 31, 2019, and the notes thereto, which are included in the 2019 Annual Report on Form 10-K, have had no material changes during the three months ended March 31, 2020.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily the result of fluctuations in interest rates and foreign exchange rates, as well as, to a lesser extent, inflation and capital market risk.

Interest Rate Risk

We are exposed to interest rate risk in the ordinary course of our business. Our cash and cash equivalents are held in readily available checking and money market accounts.

Foreign Currency Exchange Rate Risk

Due to our operations outside of the United States, we are exposed to market risk related to changes in foreign currency exchange rates. Historically, we have not hedged our foreign currency exposure. For the three months ended March 31, 2020 and 2019, changes in foreign currency exchange rates did not have a material impact on our business, financial condition, results of operations or cash flows.

Inflation Risk

We do not believe that inflation had a material effect on our business, financial condition, results of operations or cash flows for the three months ended March 31, 2020 and 2019.

Capital Market Risk

We currently have no product revenues and depend on funds raised through other sources. One possible source of funding is through further equity offerings. Our ability to raise funds in this manner depends upon capital market forces affecting our share price, including impacts on the capital markets resulting from the COVID-19 pandemic.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2020. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to its management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2020, our principal executive officer and principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation of such internal control required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the three months ended March 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

We are not currently a party to any material legal proceedings.

Item 1A. Risk Factors

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors below and the factors discussed under the caption “Risk Factors” that appear in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2019, filed with the Securities and Exchange Commission on March 2, 2020, as amended.

We, or third parties upon whom we depend, may face risks related to health epidemics, including the novel coronavirus (COVID-19) pandemic, which may delay our ability to complete our ongoing clinical trials, initiate additional clinical trials, delay regulatory activities and have other adverse effects on our business and operations.

In December 2019, a novel strain of coronavirus was first identified in Wuhan, Hubei Province, China. Since that time, multiple other countries throughout the world and their economies, including the United States, have been effectively shut down and significantly affected by the spread of the virus. To date, responsive measures such as social distancing, work-from-home policies, travel bans and quarantines have been implemented in many countries throughout the world, including the United States. We are in the midst of the global pandemic, therefore the extent to which these responsive measures may materially and adversely affect our business operations and financial condition is currently unclear and we are continuing to evaluate the situation.

As a clinical-stage company with multiple programs and multiple clinical trials currently underway, the pandemic is impacting the execution of our clinical trials. We have clinical trial sites located in countries that have been affected by COVID-19. Clinical site initiation and patient enrollment may be delayed due to prioritization of hospital resources in favor of COVID-19 patients and difficulties in recruiting clinical site investigators and clinical site staff. Some patients may not be able to comply with clinical trial protocols if quarantines impede patient movement or interrupt healthcare services, or patients may not be willing to travel to clinical trial sites. Similarly, our ability to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 and adversely impact our clinical trial operations. We may also experience delays or disruptions in our clinical trials or preclinical studies due to unforeseen circumstances at contract research organizations and vendors along their supply chain. We may also experience interruption of key clinical trial activities, such as clinical trial site data monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others or interruption of clinical trial subject visits and study procedures (particularly any procedures that may be deemed non-essential), which may impact the integrity of subject data and clinical trial endpoints.

The COVID-19 pandemic has affected and may continue to affect the operations of the FDA, EMA and other regulatory authorities, which could result in delays of reviews and approvals, including with respect to our product candidates. If regulatory matters resulting from COVID-19 continue to prevent regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could impact the ability of regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

28

We rely upon third parties for many aspects of our business, including the raw materials used to make our product candidates and the conduct of our clinical trials and preclinical studies. While we have built up inventory to assist us through this uncertain operating environment, our suppliers may be disrupted now or in the future, which may affect our ability to procure items that are essential for our research and development activities and may cause significant disruptions to our business.

We have implemented procedures to protect our workforce in manufacturing and laboratory operations while ensuring appropriate remote working protocols have been implemented for our employees who can work from home. The spread of COVID-19 and the responsive measures taken to date have limited our access to our facilities and caused the majority of our employees to work from home. We continue to monitor the global spread of COVID-19 and the response of international, national and local authorities, and have implemented and will continue to implement measures that we believe are appropriate and necessary for our business and the safety of our employees. In response to these public health directives and orders, we have implemented a work-from-home policy for our employees. The effects of the executive order, the stay-at-home advisory and our work-from-home policy may negatively impact productivity, disrupt our business and delay our clinical programs and timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course. The increase in working remotely may increase our cybersecurity risk, create data accessibility concerns, and make us more susceptible to communication disruptions. In addition, as a result of potential shelter-in-place orders or other mandated travel restrictions, our on-site staff conducting research and development and manufacturing activities may experience difficulties or delays in accessing our laboratories or manufacturing space.

Our future capital requirements depend on many factors, including the uncertain impact of the COVID-19 pandemic. The pandemic has already caused significant disruptions to the financial markets, and may continue to cause such disruptions, which could impact our ability to raise capital. Raising capital in the current economic environment, particularly in light of the economic downturn and ongoing uncertainty related to the COVID-19 pandemic, may be challenging. As a result, we may face difficulties raising capital through sales of our securities or such sales may be on unfavorable terms.

The COVID-19 global pandemic is evolving rapidly and its impact on us is highly uncertain and subject to change. We do not yet know the full extent of potential delays or long-term impacts on our business, our clinical trials, healthcare systems or the global economy. These impacts are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and actions to contain the outbreak or treat its impact, such as social distancing and quarantines or lock-downs in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease. These effects may materially adversely affect our business, financial condition, results of operations, and prospects.

Item 5. Other Information

The information set forth in this Item 5 is included herein for the purpose of providing the disclosure required under “Item 5.02 - Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers” of Form 8-K.

On May 8, 2020, the Company entered into amended and restated employment agreements (the “Employment Agreements”) with certain of its named executive officers (each, an “Executive”): Paul B. Bolno, M.D., MBA; and Chandra Vargeese, Ph.D. The Employment Agreements amend and restate the prior employment arrangements between the Company and such Executives. Under the terms of the Employment Agreements, the 2020 annual base salaries for Drs. Bolno and Vargeese are $578,977 and $434,520, respectively, and their annual target bonus percentages are 65% and 40% of their base salary, respectively.

The terms of the Employment Agreements provide that, if Drs. Bolno or Vargeese is involuntarily terminated by the Company without cause or such Executive terminates his or her employment for good reason, such Executive will be entitled to receive continued payment of his or her base salary for 18 months or 12 months, respectively, following termination; continued payment of health insurance premiums at the Company’s then normal rate of contribution until the earlier of 18 months or 12 months, respectively, following termination or until he or she commences new employment; and the payment of a separation bonus equal to his or her then annual target bonus opportunity, prorated through the termination date.

In addition, if a change of control occurs and within one year following the change of control Drs. Bolno or Vargeese is involuntarily terminated without cause or such Executive terminates his or her employment for good reason, such Executive will be entitled to receive a lump sum cash payment equal to 18 months or 12 months, respectively, of his or her then-current annual base salary; continued payment of health insurance premiums at the Company’s then normal rate of contribution until the earlier of 18 months or 12 months, respectively, following termination or until he or she commences new employment; and the payment of a separation bonus equal to his or her then annual target bonus opportunity.

Receipt of the severance and change of control benefits described above are subject to execution of a release of claims against the Company and compliance with certain restrictive covenants following the termination of his or her employment.

Copies of the Employment Agreements will be filed as exhibits to our Quarterly Report on Form 10-Q for the quarter ending June 30, 2020. The foregoing descriptions of the terms of the Employment Agreements are qualified in their entirety by reference to the full text of such exhibits.
