ARBUTUS BIOPHARMA CORPORATION

Notes to Condensed Consolidated Financial Statements
(Tabular amounts in thousands of U.S. Dollars, except share and per share amounts) 

1.      Nature of business and future operations

Arbutus Biopharma Corporation (the “Company” or “Arbutus”) is a clinical-stage biopharmaceutical company primarily focused on developing a cure for people with chronic hepatitis B virus (“HBV”) infection. The Company is advancing multiple drug product candidates that may be combined into a potentially curative regimen for chronic HBV infection. Arbutus has also initiated a drug discovery and development effort for treating coronaviruses, including COVID-19.

The Company’s pipeline includes:

AB-729, a subcutaneously-delivered RNA interference (“RNAi”) product candidate currently in a Phase 1a/1b clinical trial. Preliminary positive safety data in single-dose cohorts of healthy subjects and safety and efficacy data in the 60 mg and 180 mg single-dose cohorts in subjects with chronic HBV infection were reported in March 2020 and additional follow-on week 12 data for the 60 mg single-dose cohort were reported in May 2020. Week 12 data for the 90 mg single-dose cohort were reported in September 2020. The Company is dosing two 60 mg multi-dose cohorts of subjects with chronic HBV infection with dosing intervals of every four and eight weeks, respectively. Results from the 60 mg multi-dose cohort with a dosing interval of every four weeks and additional follow-up data on the 60 mg and 90 mg single-dose cohorts are expected to be disclosed as part of an oral presentation at the upcoming American Association for the Study of Liver Disease Conference (“AASLD”) in November. Separately, results from the 60 mg multi-dose cohort with a dosing interval of every eight weeks and a 90 mg single-dose cohort in HBV positive subjects are expected in the fourth quarter of 2020. Additionally, the Company is dosing two 90 mg multi-dose cohorts with chronic HBV infection with dosing intervals of every eight and twelve weeks, respectively;
AB-836, a next-generation capsid inhibitor product candidate currently advancing through CTA/IND-enabling studies, which the Company expects to be completed by the end of 2020; and
other compounds early in the development process, including oral compounds that inhibit PD-L1 and a next-generation oral HBV RNA destabilizer.

The Company’s research and development activities and the commercialization of its products are dependent on its ability to successfully obtain adequate financing through a combination of financing activities and operations. The success of the Company is dependent on progressing its pipeline and subsequently obtaining the necessary regulatory approvals to bring its products to market and achieving profitable operations. It is not possible to predict either the outcome of the Company’s existing or future research and development programs or the Company’s ability to continue to fund these programs in the future, nor to predict whether it will be successful in obtaining the necessary regulatory approvals to bring its products to market.

COVID-19

In December 2019, an outbreak of a novel strain of coronavirus (COVID-19) was identified in Wuhan, China. The virus continues to spread globally, has been declared a pandemic by the World Health Organization and has spread to nearly every country in the world. The impact of the pandemic has been, and will likely continue to be, extensive in many aspects of society. The pandemic has resulted in and will likely continue to result in significant disruptions to businesses. A number of countries and other jurisdictions around the world have implemented extreme measures in an attempt to slow the spread of the virus.  These measures include the closing of businesses and requiring people to stay in their homes, the latter of which raises uncertainty regarding the ability to travel to hospitals in order to participate in clinical trials. Additional measures that have had, and will likely continue to have, a major impact on clinical development, at least in the near-term, include shortages and delays in the supply chain, and prohibitions in certain countries on enrolling subjects in new clinical trials.  Despite the challenges of COVID-19, the Company has not had to alter its objectives for 2020.  However, future disruptions related to the COVID-19
6


pandemic could negatively impact the Company’s plans and timelines, including enrolling and monitoring subjects in the Company’s clinical trials.

While Arbutus’ core mission is to find a cure for hepatitis B, the magnitude of the coronavirus pandemic is undeniable. Given the Company’s proven expertise in the discovery of new antiviral therapies, Arbutus feels compelled to work towards the discovery of a new treatment. To that end, the Company has assembled an internal team of expert scientists under the direction of Arbutus’ Chief Scientific Officer, Dr. Michael Sofia, to identify novel small molecule therapies to treat COVID-19 and future coronavirus outbreaks. Dr. Sofia, who was awarded the Lasker-DeBakey Award for his discovery of sofosbuvir, brings extensive antiviral drug discovery experience to this new program. The Company has also joined the COVID R&D consortium to further support and expedite efforts to address the SARS-CoV-2 pandemic and any future coronavirus outbreaks. At this time, Arbutus’ COVID-19 research program will focus on the discovery and development of new molecular entities that address specific viral targets including the nsp12 viral polymerase and the nsp5 viral protease. The Company is actively screening multiple new oral molecular entities. These targets are essential viral proteins which Arbutus has experience in targeting.

2.      Significant accounting policies

Basis of presentation

These unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles for interim financial statements and accordingly, do not include all disclosures required for annual financial statements. These statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 Form 10-K”). These unaudited condensed consolidated financial statements reflect, in the opinion of management, all adjustments and reclassifications necessary to fairly present the Company’s financial position as of September 30, 2020, the Company’s results of operations for the three and nine months ended September 30, 2020 and the Company’s cash flows for the nine months ended September 30, 2020. The results of operations for the three and nine months ended September 30, 2020 are not necessarily indicative of the results for the full year. These unaudited condensed consolidated financial statements follow the same significant accounting policies as those described in the notes to the audited consolidated financial statements of the Company for the year ended December 31, 2019, except as described below under Recent Accounting Pronouncements.

Principles of consolidation

These unaudited condensed consolidated financial statements include the accounts of the Company and its two wholly-owned subsidiaries, Arbutus Biopharma Inc. (“Arbutus Inc.”) and Arbutus Biopharma US Holdings, Inc. All intercompany transactions and balances have been eliminated in consolidation.

Net loss attributable to common shareholders per share

The Company follows the two-class method when computing net loss attributable to common shareholders per share as the Company has issued Series A participating convertible preferred shares (the “Preferred Shares”), as further described in note 11, that meet the definition of participating securities. The Preferred Shares entitle the holders to participate in dividends but do not require the holders to participate in losses of the Company. Accordingly, if the Company reports a net loss attributable to holders of the Company’s common shares, net losses are not allocated to holders of the Preferred Shares.

Net loss attributable to common shareholders per share is calculated based on the weighted average number of common shares outstanding. The calculation of diluted net loss attributable to common shareholders per share does not differ from the calculation of basic net loss attributable to common shareholders per share, as the effect of the Company’s dilutive potential common shares was anti-dilutive. During the nine months ended September 30, 2020 and 2019, potential common shares of 31.6 million and 28.2 million, respectively, consisting of the “if-converted” number of Preferred Shares and outstanding stock and Employee Stock Purchase Plan (“ESPP”) options, were excluded from the calculation of diluted net loss per common share because their inclusion would be anti-dilutive.

Revenue recognition

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (”ASC 606”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers under a five-step model: (i) identify contract(s) with a customer; (ii) identify the performance obligations
7


in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when or as a performance obligation is satisfied.

The Company generates revenue primarily through collaboration agreements and license agreements. Such agreements may require the Company to deliver various rights and/or services, including intellectual property rights or licenses and research and development services. Under such agreements, the Company is generally eligible to receive non-refundable upfront payments, funding for research and development services, milestone payments, and royalties.

In contracts where the Company has more than one performance obligation to provide its customer with goods or services, each performance obligation is evaluated to determine whether it is distinct based on whether (i) the customer can benefit from the good or service either on its own or together with other resources that are readily available and (ii) the good or service is separately identifiable from other promises in the contract. The consideration under the contract is then allocated between the distinct performance obligations based on their respective relative stand-alone selling prices. The estimated stand-alone selling price of each deliverable reflects the Company’s best estimate of what the selling price would be if the deliverable was regularly sold on a stand-alone basis and is determined by reference to market rates for the good or service when sold to others or by using an adjusted market assessment approach if the selling price on a stand-alone basis is not available.

The consideration allocated to each distinct performance obligation is recognized as revenue when control is transferred to the customer for the related goods or services. Consideration associated with at-risk substantive performance milestones, including sales-based milestones, is recognized as revenue when it is probable that a significant reversal of the cumulative revenue recognized will not occur. Sales-based royalties received in connection with licenses of intellectual property are subject to a specific exception in the revenue standards, whereby the consideration is not included in the transaction price and recognized in revenue until the customer’s subsequent sales or usages occur.

Segment information

The Company operates as a single segment.

Recent accounting pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s financial position or results of operations upon adoption.

In June 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments (ASC 326). The guidance is effective for the Company beginning January 1, 2023 and it changes how entities account for credit losses on financial assets and other instruments that are not measured at fair value through net income, including available-for-sale debt securities. The Company is currently evaluating the impact of the new standard on its consolidated financial statements.

3.    Fair value of financial instruments

The Company measures certain financial instruments and other items at fair value.

To determine the fair value, the Company uses the fair value hierarchy for inputs used in measuring fair value that maximize the use of observable inputs and minimize the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use to value an asset or liability and are developed based on market data obtained from independent sources. Unobservable inputs are inputs based on assumptions about the factors market participants would use to value an asset or liability. The three levels of inputs that may be used to measure fair value are as follows:
 
Level 1 inputs are quoted market prices for identical instruments available in active markets.
Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly. If the asset or liability has a contractual term, the input must be observable for substantially the full term. An example includes quoted market prices for similar assets or liabilities in active markets.
8


Level 3 inputs are unobservable inputs for the asset or liability and will reflect management’s assumptions about market assumptions that would be used to price the asset or liability.

Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy.

The carrying values of cash and cash equivalents, investments in marketable securities, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the immediate or short-term maturity of these financial instruments.

To determine the fair value of the contingent consideration (note 8), the Company uses a probability weighted assessment of the likelihood the milestones would be met and the estimated timing of such payments, and then the potential contingent payments were discounted to their present value using a probability adjusted discount rate that reflects the early stage nature of the development program, time to complete the program development, and overall biotech indices. The Company determined the fair value of the contingent consideration was $3.3 million as of September 30, 2020 and the increase of $0.3 million has been recorded as a component of total operating expenses in the statement of operations and comprehensive loss for the nine months ended September 30, 2020. The assumptions used in the discounted cash flow model are level 3 inputs as defined above. The Company assessed the sensitivity of the fair value measurement to changes in these unobservable inputs, and determined that changes within a reasonable range would not result in a materially different assessment of fair value.  

The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis, and indicates the level within the fair value hierarchy of the valuation techniques used to determine such fair value:

There were no realized gains or losses for the three and nine months ended September 30, 2020 or 2019.

5.     Investment in Genevant

In April 2018, Arbutus entered into an agreement with Roivant Sciences Ltd. (“Roivant”), its largest shareholder, to launch Genevant Sciences Ltd. (“Genevant”), a company focused on the discovery, development, and commercialization of a broad range of RNA-based therapeutics enabled by Arbutus’ lipid nanoparticle (“LNP”) and ligand conjugate delivery technologies. Arbutus licensed exclusive rights to its LNP and ligand conjugate delivery platforms to Genevant for RNA-based applications outside of HBV, except to the extent certain rights had already been licensed to other third parties. Arbutus retained all rights to its LNP and conjugate delivery platforms for HBV. Arbutus is entitled to receive tiered low single-digit royalties on future sales of Genevant products covered by the licensed patents. If Genevant sub-licenses the intellectual property licensed by Arbutus to Genevant, Arbutus would receive upon the commercialization of a product developed by such sub-licensee the lesser of (i) twenty percent of the revenue received by Genevant for such sublicensing and (ii) tiered low single-digit royalties on product sales by the sublicensee.

On July 23, 2020, the United States Patent and Trademark Office before the Patent Trial and Appeal Board ("PTAB") announced their decision in Moderna Therapeutics, Inc.'s challenge of the validity of U.S. Patent 8,058,069 ("the '069 Patent"). In this decision, the PTAB determined no challenged claims were unpatentable. While Arbutus is the patent holder, this patent has been licensed to Genevant. The '069 Patent was included in the license agreement between Genevant and Arbutus.

On July 31, 2020, Genevant was recapitalized through an equity investment and conversion of previously issued convertible debt securities held by Roivant. In addition, Arbutus participated in the recapitalization of Genevant with an investment of $2.5 million. Arbutus determined that this $2.5 million additional investment in Genevant represented the funding of prior losses and accordingly, the Company recorded the amount as an equity investment loss on the Condensed Consolidated Statements of Operations and Comprehensive Loss during the three months ended September 30, 2020.

Following the recapitalization, Arbutus owned approximately 16% of the common equity of Genevant. In connection with the recapitalization, Genevant, Arbutus and Roivant entered into an Amended and Restated Shareholders Agreement that provides Roivant with substantial control of Genevant. Arbutus has a non-voting observer seat on Genevant’s Board of Directors. Due to Arbutus’ loss of significant influence with respect to Genevant as a result of the recapitalization, Arbutus discontinued the use of the equity method of accounting for its interest in Genevant. Following the recapitalization, Arbutus accounts for its interest in Genevant as equity securities without readily determinable fair values. Accordingly, an estimate of the fair value of the securities is based on the original cost less previously recognized equity method losses, less impairments, plus or minus changes resulting from observable price changes in orderly transactions for identical or a similar Genevant securities. As of September 30, 2020, the carrying value of Arbutus’ investment in Genevant was zero and Arbutus owned approximately 16% of the common equity of Genevant.

Arbutus’ entitlement to receive future royalties or sublicensing revenue from Genevant was not impacted by the recapitalization.

7.    Sale of future royalties
On July 2, 2019, the Company entered into a Purchase and Sale Agreement (the “Agreement”) with the Ontario Municipal Employees Retirement System (or “OMERS”), pursuant to which the Company sold to OMERS part of its royalty interest on future global net sales of ONPATTRO® (Patisiran) (“ONPATTRO”), an RNAi therapeutic currently being sold by Alnylam Pharmaceuticals, Inc. (“Alnylam”).

ONPATTRO utilizes Arbutus’ LNP technology, which was licensed to Alnylam pursuant to the Cross-License Agreement, dated November 12, 2012, by and between the Company and Alnylam (the “LNP License Agreement”). Under the terms of the LNP License Agreement, the Company is entitled to tiered royalty payments on global net sales of ONPATTRO ranging from 1.00% to 2.33% after offsets, with the highest tier applicable to annual net sales above $500 million. This royalty interest was sold to OMERS, effective as of January 1, 2019, for $20 million in gross proceeds before advisory fees. OMERS will retain this entitlement until it has received $30 million in royalties, at which point 100% of such royalty interest on future global net sales of ONPATTRO will revert to the Company. OMERS has assumed the risk of collecting up to $30 million of future royalty payments from Alnylam and Arbutus is not obligated to reimburse OMERS if they fail to collect any such future royalties.

The $30 million in royalties to be collected by OMERS is accounted for as a liability, with the difference between the liability and the gross proceeds received accounted for as a discount. The discount, as well as $1.5 million of transaction costs, will be amortized as interest expense based on the projected balance of the liability as of the beginning of each period. Over the course of the Agreement, the actual interest rate will be affected by the amount and timing of royalty revenue recognized and changes in the timing of forecasted royalty revenue. On a quarterly basis, the Company will reassess the expected timing of the royalty revenue, recalculate the amortization and effective interest rate and adjust the accounting prospectively as needed. As of September 30, 2020, the effective annual interest rate was approximately 22%.

The Company will recognize non-cash royalty revenue related to the sales of ONPATTRO during the term of the Agreement. As royalties are remitted to OMERS from Alnylam, the balance of the recognized liability will be effectively repaid over the life of the Agreement. From the inception of the royalty sale through September 30, 2020, the Company has recorded an aggregate of $3.7 million of non-cash royalty revenue for royalties earned by OMERS. There are a number of factors that could materially affect the amount and timing of royalty payments from Alnylam, none of which are within the Company’s control.

During the three and nine months ended September 30, 2020, the Company recognized non-cash royalty revenue of $0.7 million and $2.0 million, respectively, and $1.1 million and $3.2 million of related non-cash interest expense, respectively. During the three and nine months ended September 30, 2019, the Company recognized non-cash royalty revenue of $0.5 million and $1.0 million, respectively, and $1.1 million of related non-cash interest expense during the three and nine months ended September 30, 2019.
The table below shows the activity related to the net liability for 2020:
Nine Months Ended September 30, 2020
(in thousands)
Net liability related to sale of future royalties - beginning balance $ 18,992 
Non-cash royalty revenue (2,041)
Non-cash interest expense 3,166 
Net liability related to sale of future royalties - ending balance $ 20,117 

In addition to the royalty from the LNP License Agreement, the Company is also receiving a second, lower royalty interest on global net sales of ONPATTRO originating from a settlement agreement and subsequent license agreement with Acuitas Therapeutics, Inc. (“Acuitas”). The royalty from Acuitas has been retained by the Company and was not part of the royalty sale to OMERS.

8.      Contingencies and commitments

Product development partnership with the Canadian Government

The Company entered into a Technology Partnerships Canada (“TPC”) agreement with the Canadian Federal Government on November 12, 1999.  Under this agreement, TPC agreed to fund 27% of the costs incurred by the Company, prior to March 31, 2004, in the development of certain oligonucleotide product candidates up to a maximum contribution from TPC of $7.2 million (C$9.3 million).  The Company received a cumulative contribution of $2.7 million (C$3.7 million).  In return for the funding provided by TPC, the Company agreed to pay royalties on the share of future licensing and product revenue, if any, that is received by the Company on certain non-RNAi oligonucleotide product candidates covered by the funding under the agreement.  These royalties are payable until a certain cumulative payment amount is achieved or until a pre-specified date.  In addition, until a cumulative amount equal to the funding actually received under the agreement has been paid to TPC, the Company agreed to pay 2.5% royalties on any royalties the Company receives on sales of Acrotech Biopharma LLC’s Marqibo® (formerly Spectrum Pharmaceuticals, Inc.). For each of the nine months ended September 30, 2020 and 2019, the Company earned royalties on Marqibo sales in the amount of $0.2 million. The resulting royalties payable by the Company to TPC were not material in either period. The cumulative amount paid or accrued up to September 30, 2020 was less than $0.1 million, resulting in the contingent amount due to TPC being $2.7 million (C$3.7 million).

Arbitration with the University of British Columbia

Certain early work on lipid nanoparticle delivery systems and related inventions was undertaken at the University of British Columbia (“UBC”), as well as by the Company that was subsequently assigned to UBC. These inventions are licensed to the Company by UBC under a license agreement, initially entered into in 1998 and amended in 2001, 2006 and 2007. The Company has granted sublicenses under the UBC license to certain third parties, including Alnylam.  In November 2014, UBC filed a demand for arbitration against the Company and in January 2015, filed a Statement of Claim, which alleged entitlement to $3.5 million in allegedly unpaid royalties based on publicly available information, and an unspecified amount based on non-public information. UBC also sought interest and costs, including legal fees. The Company filed its Statement of Defense to UBC’s Statement of Claims, as well as a Counterclaim involving a patent application that the Company alleged UBC wrongly licensed to a third party. The proceedings were divided into three phases, with the first hearing taking place in June 2017. In the first phase, the arbitrator determined which agreements are sublicense agreements within UBC’s claim. Also in the first phase, UBC updated its alleged entitlement from $3.5 million originally claimed to seek $10.9 million in alleged unpaid royalties, plus interest arising from payments as early as 2008. The arbitrator also held in the first phase of the arbitration that the patent application that is the subject of the Counterclaim was not required to be licensed to the Company. The second phase of the arbitration took place in the second quarter of 2019. In August 2019, the arbitrator issued his decision for the second phase of the arbitration, awarding UBC $5.9 million, which includes interest of approximately $2.6 million. The Company paid the $5.9 million award to UBC in September 2019. The arbitrator also held that the third phase of the arbitration, which would address patent validity, should the Company choose to pursue a third phase, would not provide a defense to the award. An award for costs and attorneys’ fees is still to be determined. The Company has accrued $0.4 million for an estimate of a potential award for costs and attorneys’ fees as of September 30, 2020.

Stock Purchase Agreement with Enantigen

In October 2014, Arbutus Inc., our wholly-owned subsidiary, acquired all of the outstanding shares of Enantigen Therapeutics, Inc. (“Enantigen”) pursuant to a stock purchase agreement. Through this transaction, Arbutus Inc. acquired an HBV surface antigen secretion inhibitor program and a capsid assembly inhibitor program.

Under the stock purchase agreement, Arbutus Inc. agreed to pay up to a total of $21.0 million to Enantigen’s selling stockholders upon the achievement of specified development and regulatory milestones for (a) the first two products that contain either a capsid compound or an HBV surface antigen compound that is covered by a patent acquired under this agreement, or (b) a capsid compound from an agreed upon list of compounds. The development milestones are tied to programs which are no longer under development by the Company, and therefore the contingency related to these milestones has been reduced to zero.

An additional $102.5 million may also be paid to Enantigen’s selling stockholders related to the achievement of certain sales performance milestones in connection with the sale of the first commercialized product by Arbutus Inc. for the treatment of HBV, regardless of whether such product is based upon assets acquired under this agreement, and a low single-digit royalty on net sales of such first commercialized HBV product, up to a maximum royalty payment of $1.0 million that, if paid, would be offset against Arbutus Inc.’s milestone payment obligations.
13



The contingent consideration for this acquisition is a financial liability, which is measured at its fair value at each reporting period, with any changes in fair value from the previous reporting period recorded in the statements of operations and comprehensive loss (see note 3). The fair value of the contingent consideration was $3.3 million as of September 30, 2020.

9.      Collaborations, contracts and licensing agreements

Revenue contracts are described in detail in the Overview section of Part II, Item 8, “Financial Statements and Supplementary Data” in the Company’s 2019 Form 10-K.

Assembly BioSciences, Inc.

In August 2020, the Company and Assembly BioSciences, Inc. (“Assembly”) entered into a clinical collaboration agreement to evaluate the Company’s proprietary GalNAC delivered RNAi therapeutic AB-729 in combination with Assembly’s lead HBV core inhibitor (capsid inhibitor) candidate vebicorvir and a standard-of-care nucleos(t)ide reverse transcriptase inhibitor (Nrtl) therapy for the treatment of patients with chronic HBV infection. The companies will share in the costs of the collaboration and the associated clinical trial is projected to initiate in the first half of 2021. The Company incurred no costs related to the collaboration during the three months ended September 30, 2020.

Alnylam Pharmaceuticals, Inc. and Acuitas Therapeutics, Inc.

The Company has two royalty entitlements to Alnylam’s global net sales of ONPATTRO.

In 2012, the Company entered into a license agreement with Alnylam that entitles Alnylam to develop and commercialize products with the Company’s LNP technology. Alnylam’s ONPATTRO, which represents the first approved application of the Company’s LNP technology, was approved by the United States Food and Drug Administration (“FDA”) and the European Medicines Agency (“EMA”) during the third quarter of 2018 and was launched by Alnylam immediately upon approval in the United States. Under the terms of this license agreement, the Company is entitled to tiered royalty payments on global net sales of ONPATTRO ranging from 1.00% - 2.33% after offsets, with the highest tier applicable to annual net sales above $500 million. This royalty interest was sold to OMERS, effective as of January 1, 2019, for $20 million in gross proceeds before advisory fees. OMERS will retain this entitlement until it has received $30 million in royalties, at which point 100% of this royalty entitlement on future global net sales of ONPATTRO will revert back to the Company. OMERS has assumed the risk of collecting up to $30 million of future royalty payments from Alnylam and the Company is not obligated to reimburse OMERS if they fail to collect any such future royalties. If this royalty entitlement reverts to the Company, it has the potential to provide an active royalty stream or to be otherwise monetized again in full or in part.
The Company also has rights to a second, lower royalty interest on global net sales of ONPATTRO originating from a settlement agreement and subsequent license agreement with Acuitas.  This royalty entitlement from Acuitas has been retained by the Company and was not part of the royalty entitlement sale to OMERS.

10. Stockholders’ equity
 
Open Market Sales Agreement

In December 2018, the Company entered into an Open Market Sale Agreement with Jefferies LLC (“Jefferies”) (the “Sale Agreement”), under which it could issue and sell common shares, from time to time, for an aggregate sales price of up to $50.0 million. In December 2019, the Company entered into an amendment to the Sale Agreement with Jefferies (the “2019 Amendment”) in connection with the filing of a shelf registration statement on Form S-3 (File No. 333-235674), filed with the SEC on December 23, 2019 (the “Shelf Registration Statement”). The 2019 Amendment revised the original Sale Agreement to reflect that the Company could sell its common shares, without par value, from time to time, for an aggregate sales price of up to $50 million, under the Shelf Registration Statement. In July 2020, the Company fully utilized the remaining availability under the Sale Agreement, as amended by the 2019 Amendment. In August 2020, the Company entered into a new amendment to the Sale Agreement (the “2020 Amendment”) with Jefferies. Pursuant to the 2020 Amendment, the Company can issue and sell common shares, from time to time, for an aggregate sales price of up to $75 million under the Sale Agreement, as amended.

For the nine months ended September 30, 2019, the Company issued 1,208,090 common shares pursuant to the Sale Agreement resulting in net proceeds of approximately $5.2 million. There were no shares issued under the Sale Agreement during the three months ended September 30, 2019.

During the three and nine months ended September 30, 2020, the Company issued 13,258,096 and 19,696,361 common shares pursuant to the Sale Agreement, as amended, resulting in net proceeds of approximately $48.8 million and $66.1 million, respectively.

As of September 30, 2020, there was approximately $62.3 million available under the Sale Agreement, as amended.

Stock-based compensation

The table below summarizes information about the Company’s stock based compensation for the three and nine months ended September 30, 2020 and 2019 and the expense recognized in the condensed consolidated statements of operations:

Awards with performance conditions are expensed when it is probable that the performance condition will be achieved. For each of the three and nine months ended September 30, 2020, $0.3 million was expensed for stock option awards with performance conditions. These expenses are included in the table above.

Employee Stock Purchase Plan

In May 2020, the Company’s stockholders approved the 2020 Employee Stock Purchase Plan which became effective on May 28, 2020. A total of 1.5 million common shares were reserved for issuance under the ESPP. Company employees contribute funds via payroll deductions, which are used to buy Company common shares at a discount of up to 15% based on the lower of the price at the start of the offering period and at the end of the relevant purchase period within such offering period. The initial offering period under the ESPP is September 1, 2020 through August 31, 2021 with purchase dates set on February 26, 2021 and August 31, 2021. All 1.5 million common shares remained available for future issuance under the plan at September 30, 2020. For the three and nine months ended September 30, 2020, the Company recognized less than $0.1 million of stock-based compensation expense related to the ESPP, which is included in the table above.

Series A Preferred Shares

In October 2017, the Company entered into a subscription agreement with Roivant for the sale of 1,164,000 Preferred Shares for gross proceeds of $116.4 million. These Preferred Shares are non-voting and accrue an 8.75% per annum coupon in the form of additional Preferred Shares, compounded annually, until October 16, 2021, at which time all the Preferred Shares will be subject to mandatory conversion into common shares (subject to limited exceptions in the event of certain fundamental corporate transactions relating to Arbutus’s capital structure or assets, which would permit earlier conversion at Roivant’s option). The conversion price is $7.13 per share, which will result in the Preferred Shares being converted into approximately 23 million common shares. After conversion of the Preferred Shares into common shares, based on the number of common shares outstanding as of September 30, 2020, Roivant will hold approximately 36% of the Company’s common shares. Roivant agreed to a four year lock-up period for this investment and its existing holdings in the Company. Roivant also agreed to a four year standstill whereby Roivant will not acquire greater than 49.99% of the Company’s common shares or securities convertible into common shares. The initial investment of $50.0 million closed in October 2017, and the remaining amount of $66.4 million closed in January 2018 following regulatory and shareholder approvals.

The Company records the Preferred Shares wholly as equity under ASC 480, Distinguishing Liabilities From Equity, with no bifurcation of the conversion feature from the host contract, given that the Preferred Shares cannot be cash settled and the redemption features are within the Company’s control, which include a fixed conversion ratio with predetermined timing and proceeds. The Company accrues for the 8.75% per annum compounding coupon at each reporting period end date as an increase to preferred share capital, and an increase to deficit (see Condensed Consolidated Statement of Stockholders’ Equity).

11.      Related Party Transactions

On July 31, 2020, Genevant was recapitalized through an equity investment and conversion of previously issued convertible debt securities held by Roivant. In addition, Arbutus participated in the recapitalization with an investment of $2.5 million. Following the recapitalization, Arbutus owned approximately 16% of the common equity of Genevant. See note 5 for more information.

Through the first quarter of 2019, the Company purchased certain research and development services from Genevant. These services were billed at agreed hourly rates and were reflective of market rates for such services.  The total cost of these services during 2019 was less than $0.1 million, which was included in the Condensed Consolidated Statement of Operations under research and development. There were no such costs incurred during 2020.

Conversely, Genevant purchased certain administrative and transitional services from the Company totaling less than $35 thousand for each of the three and nine months ended September 30, 2020. The total income from these services was $40 thousand and $284 thousand for the three and nine months ended September 30, 2019. This income is netted against research and development expenses in the condensed consolidated statements of operations.

In addition, during 2019 Genevant had a sublease for 17,900 square feet in the Company’s Burnaby facility. Sublease income from Genevant was $21 thousand and $145 thousand for the three and nine months ended September 30, 2019, and was netted against site consolidation costs and lease liability. The Company’s Burnaby facility lease and the corresponding sublease to Genevant expired on July 31, 2019.

OVERVIEW

Arbutus is a clinical-stage biopharmaceutical company primarily focused on developing a cure for people with chronic hepatitis B virus (“HBV”) infection. We are advancing multiple drug product candidates that may be combined into a potentially curative regimen for chronic HBV infection. We have also initiated a drug discovery and development effort for treating coronaviruses, including COVID-19.

Hepatitis B is a potentially life-threatening liver infection caused by HBV. HBV can cause chronic infection which leads to a higher risk of death from cirrhosis and liver cancer. Chronic HBV infection represents a significant unmet medical need. The World Health Organization estimates that over 250 million people worldwide suffer from chronic HBV infection, while other estimates indicate that approximately 2 million people in the United States suffer from chronic HBV infection. Approximately 900,000 people die every year from complications related to chronic HBV infection despite the availability of effective vaccines and current treatment options.

Today’s current treatment options include nucleos(t)ide analogs (“NA”) and pegylated interferon regimens (“Peg-IFN”). However, less than 5% of patients are cured by these current treatment options after a finite treatment duration. With such low cure rates, most patients with chronic HBV infection are required to take NA therapy daily for the rest of their lives.

Our focus is on developing new HBV treatment regimens with finite treatment durations and higher cure rates. We define a cure as a functional cure where HBV DNA replication and hepatitis B surface antigen (“HBsAg”) expression are reduced to undetectable levels and this level of expression is sustained six months after a finite duration of therapy. Our HBV product pipeline includes RNA interference (“RNAi”) therapeutics, oral capsid inhibitors, oral compounds that inhibit PD-L1 and oral HBV RNA destabilizers. We believe a combination of these product candidates could lead to a curative treatment regimen with a finite duration for patients with chronic HBV infection.

There is a compelling market opportunity for an HBV curative regimen. Currently, an estimated 27 million (10.5%) of a total of over 250 million people worldwide with chronic HBV infection are diagnosed and approximately 4.5 million (1.8%) are on treatment. We believe that the introduction of an HBV curative regimen with a finite duration would substantially increase diagnosis and treatment rates for patients with chronic HBV.
 
Strategy

Our business strategy is to develop a curative combination regimen for patients with chronic HBV infection. We believe this can best be achieved by:

developing a broad portfolio of proprietary therapeutic assets that target multiple elements of the HBV viral lifecycle, most importantly suppressing HBV replication and HBsAg expression;
developing compounds that reawaken the host immune response;
identifying a combination of therapeutic assets with complementary mechanisms of action that can deliver higher cure rates with a finite treatment duration; and
advancing a curative combination regimen through clinical development, regulatory approval and commercial launch.

Additionally, we have initiated an internal research program to identify new small molecule antiviral medicines to treat COVID-19 and future coronavirus outbreaks.

Our product candidates are first evaluated in Phase 1 clinical trials as a monotherapy or in combination with other currently-marketed therapies to assess patient safety and antiviral activity. We are currently conducting a Phase 1a/1b clinical trial and performing pre-clinical and investigational new drug (“IND”)-enabling studies for our HBV product candidates. Results from our Phase 1 clinical trials and other studies will inform the design of future Phase 2 and Phase 3 clinical trials that will evaluate a combination of our therapeutic agents in a potentially curative combination regimen.

Our Product Candidates

Given the biology of HBV, we believe therapeutic success will require a combination of agents with complementary mechanisms of action. We are developing product candidates that have the potential to reduce HBsAg expression, suppress HBV DNA replication and reawaken the immune response in patients with chronic HBV.
19



Our HBV product pipeline consists of the following programs:
     ABUS-20200930_G1.JPG

We believe that AB-729, our subcutaneously administered RNAi product candidate, may be combinable with AB-836, our lead capsid inhibitor product candidate, and other currently-marketed or investigational therapies, in our first proprietary combination therapy for chronic HBV patients. In parallel, we are in lead optimization with several oral compounds for our PD-L1 program and our next-generation HBV RNA destabilizer program. In addition, we announced in August 2020, that we entered into a clinical collaboration agreement with Assembly BioSciences, Inc. (“Assembly”) to evaluate AB-729 in combination with Assembly’s lead HBV core inhibitor (capsid inhibitor) candidate vebicorvir (VBR) and standard-of-care nucleos(t)ide reverse transcriptase inhibitor (“NrtI”) therapy for the treatment of patients with chronic HBV infection. This collaboration will include a randomized, multi-center, open-label Phase 2 clinical trial that will explore the safety, pharmacokinetics, and antiviral activity of the triple combination of AB-729, VBR and an NrtI compared to the double combinations of VBR with an NrtI and AB-729 with an NrtI. This trial is expected to initiate in the first half of 2021 and enroll approximately 60 virologically-suppressed subjects with chronic HBV infection.

We continue to explore expansion of our HBV pipeline through internal discovery and development activities and through potential strategic alliances.

GalNAc RNAi (AB-729)

RNAi therapeutics represent a recent significant advancement in drug development. RNAi therapeutics utilize a natural pathway within cells to silence genes by eliminating the disease-causing proteins that they code for. We are developing RNAi therapeutics that are designed to reduce HBsAg expression and other HBV antigens in patients chronically infected with HBV. Reducing HBsAg is widely believed to be a key prerequisite to enable a patient’s immune system to reawaken and respond against the virus.

AB-729 is a subcutaneously-delivered RNAi therapeutic targeted to hepatocytes using our novel covalently conjugated GalNAc delivery technology. AB-729 inhibits viral replication and reduces all HBV antigens. In July 2019, we initiated a single- and multi-dose Phase 1a/1b clinical trial for AB-729, designed to investigate the safety, tolerability, pharmacokinetics, and pharmacodynamics of AB-729 in healthy volunteers and in chronic HBV subjects.

The ongoing first-in-human clinical trial of AB-729 consists of three parts:
In Part 1, three cohorts of healthy subjects were randomized 4:2 to receive single doses (60 mg, 180 mg or 360 mg) of AB-729 or placebo.
In Part 2, non-cirrhotic, HBeAg positive or negative, chronic hepatitis B subjects (n=6) currently taking nucleos(t)ide antiviral therapy with HBV DNA below the limit of quantitation received single doses (60 mg, 90 mg or 180 mg) of
20


AB-729. All subjects continued their nucleos(t)ide antiviral therapy throughout the trial. Part 2 will also include dosing of AB-729 in HBV DNA positive chronic hepatitis B subjects.
In Part 3, chronic hepatitis B subjects, HBV DNA negative first and HBV DNA positive later, will receive multiple doses of AB-729 for up to six months at four, eight or twelve week dosing intervals.

In March 2020, we announced positive preliminary results in the three cohorts of healthy subjects, all of whom received a single subcutaneous injection of AB-729 with no serious adverse events (“SAEs”) observed and most adverse events (“AEs”) were mild and considered unrelated to AB-729. Two subjects in the 360 mg cohort had asymptomatic, reversible Grade 3 ALT elevations assessed as related to AB-729. Neither subject had meaningful changes in any other laboratory parameter excepting Grade 1 or 2 AST elevation. There were no other clinically relevant abnormalities in laboratory tests, ECGs, or vital signs.

In March 2020, we also announced positive preliminary results in two cohorts (60 mg and 180 mg dose groups) of chronic hepatitis B subjects and, in May 2020, we announced additional Week 12 follow-up data on the 60 mg cohort. Week 12 data for the 90 mg single-dose cohort were reported in September 2020. All chronic hepatitis B subjects were on nucleos(t)ide antiviral therapy and received a single subcutaneous injection of AB-729.

Mean HBsAg changes from baseline:
60 mg Single-Dose
Cohort (B)
(N=6)
90 mg Single-Dose
Cohort (C)
(N=6)
180 mg Single-Dose
Cohort (A)
(N=4)
Week 12 (day 84) mean log10 IU/mL (Standard Error of the Mean) -0.99 (0.24)   -1.23 (0.18) -0.98 (0.22)


All single-dose cohorts achieved meaningful week 12 mean log10 (SE) HBsAg declines and the 60 mg and 90 mg single doses demonstrated favorable safety and tolerability profiles with no SAEs.  Most AEs were mild (13/15) and considered unrelated (12/15) to AB-729. One subject receiving the 180 mg dose who experienced the highest HBsAg decline also experienced a Grade 3 ALT/AST flare. Notably, this subject experienced an unrelated gastroenteritis and self-medicated. 

We are currently dosing two 60 mg multi-dose cohorts of subjects with chronic HBV infection with dosing intervals of every four and eight weeks, respectively. Results from the 60 mg multi-dose cohort with a dosing interval of every four weeks and additional follow-up data on the 60 mg and 90 mg single-dose cohorts are expected to be disclosed as part of an oral presentation at the upcoming American Association for the Study of Liver Disease Conference (“AASLD”) in November. Separately, results from the 60 mg multi-dose cohort with a dosing interval of every eight weeks and a 90 mg single-dose cohort in HBV DNA positive subjects are expected in the fourth quarter of 2020. Additionally, the Company is dosing two 90 mg multi-dose cohorts of subjects with chronic HBV infection with dosing intervals of every eight and twelve weeks, respectively.

While we have been able to progress with our clinical and pre-clinical activities to date, it is not possible to predict if the COVID-19 pandemic will negatively impact our plans and timelines, including enrolling and monitoring subjects in the trial.

HBV RNA Destabilizers

HBV RNA destabilizers are small molecule orally active agents that cause the destabilization and ultimate degradation of HBV RNAs. These agents result in the reduction of HBsAg and other viral proteins in both whole cell systems and animal models. They have the potential to selectively impact HBV versus other RNA or DNA viruses and demonstrate pangenotypic characteristics. HBV RNA destabilizers have demonstrated additive effects in combination with other anti-HBV mechanisms of action. HBV RNA destabilizers have the potential to complement or replace subcutaneously delivered RNAi agents with an oral therapy in combination with a capsid inhibitor and an approved NA.

In February 2020, we discontinued the development of AB-452, our first-generation oral HBV RNA destabilizer product candidate following extensive preclinical evaluations. However, oral HBV RNA destabilizers have shown compelling anti-viral effects in multiple HBV pre-clinical models and we believe this target offers potential for an oral HBsAg reducing agent and potentially an all oral combination HBV therapy. Given this, we continue to advance next-generation oral HBV RNA-destabilizers with chemical scaffolds distinct from AB-452 through lead optimization.

Capsid Inhibitors (AB-836)

HBV core protein assembles into a capsid structure, which is required for viral replication. The current commercially available therapies (NAs or Peg-IFN) significantly reduce HBV DNA levels in the serum, but HBV replication continues in the liver, thereby enabling HBV infection to persist. More effective therapies for patients require new agents which will further block viral replication. We are developing capsid inhibitors (also known as core protein inhibitors) as oral therapeutics which, in combination with NAs, could further reduce HBV replication. By inhibiting assembly of functional viral capsids, the ability of HBV to replicate is impaired. Capsid inhibitor molecules also inhibit the uncoating step of the viral life cycle and thus reduce the formation of cccDNA, the viral reservoir which resides in the cell nucleus, and which is believed to play a role in viral persistence.

Our oral capsid inhibitor discovery effort generated promising next-generation compounds, which led to the nomination of AB-836 in January 2020. AB-836 is a novel chemical series differentiated from competitor compounds with the potential for increased efficacy and an enhanced resistance profile. AB-836 leverages a novel binding site within the core protein dimer-dimer interface, has shown to be active against NA resistant variants and has the potential to address certain known capsid resistant variants. AB-836 is anticipated to be combinable with other mechanisms of action and is also anticipated to be dosed once daily. We anticipate completing CTA/IND-enabling studies for AB-836 by the end of 2020.

Immune Reawakening

We are in lead optimization with oral compounds which are potentially capable of reawakening patients’ HBV-specific immune response by inhibiting PD-L1. These compounds complement our pipeline of agents and could potentially be an important part of a combination therapy for the treatment of HBV.

COVID-19

In December 2019, an outbreak of a novel strain of coronavirus (COVID-19) was identified in Wuhan, China. This virus continues to spread globally, has been declared a pandemic by the World Health Organization and has spread to nearly every country in the world. The impact of this pandemic has been, and will likely continue to be, extensive in many aspects of society. The pandemic has resulted in and will likely continue to result in significant disruptions to businesses. A number of countries and other jurisdictions around the world have implemented extreme measures to try and slow the spread of the virus.  These measures include the closing of businesses and requiring people to stay in their homes, the latter of which raises uncertainty regarding the ability to travel to hospitals in order to participate in clinical trials. Additional measures that have had, and will likely continue to have, a major impact on clinical development, at least in the near-term, include shortages and delays in the supply chain, and prohibitions in certain countries on enrolling subjects in new clinical trials.  Despite the challenges of COVID-19, we have not had to alter our objectives for 2020.  However, future disruptions related to the COVID-19 pandemic could negatively impact our plans and timelines, including enrolling and monitoring subjects in the trial.

While our core mission is to find a cure for hepatitis B, the magnitude of the coronavirus pandemic is undeniable. Given our proven expertise in the discovery of new antiviral therapies, we feel compelled to work towards the discovery of a new treatment. To that end, we have assembled an internal team of expert scientists under the direction of our Chief Scientific Officer, Dr. Michael Sofia, to identify novel small molecule therapies to treat COVID-19 and future coronavirus outbreaks. Dr. Sofia, who was awarded the Lasker-DeBakey Award for his discovery of sofosbuvir, brings extensive antiviral drug discovery experience to this new program. We have also recently joined the COVID R&D consortium to further support and expedite efforts to address the SARS-CoV-2 pandemic and any future coronavirus outbreaks. At this time, our COVID-19 research program will focus on the discovery and development of new molecular entities that address specific viral targets including the nsp12 viral polymerase and the nsp5 viral protease. These targets are essential viral proteins which we have experience in targeting. We are actively screening multiple new oral molecular entities.

Royalty Entitlements and Collaborations

Alnylam Pharmaceuticals, Inc. and Acuitas Therapeutics, Inc.

The Company has two royalty entitlements to Alnylam Pharmaceuticals, Inc.’s (“Alnylam”) global net sales of ONPATTRO® (“ONPATTRO”).

22


In 2012, we entered into a license agreement with Alnylam that entitles Alnylam to develop and commercialize products with our lipid nanoparticle (“LNP”) delivery technology. Alnylam’s ONPATTRO, which represents the first approved application of our LNP technology, was approved by the United States Food and Drug Administration (“FDA”) and the European Medicines Agency (“EMA”) during the third quarter of 2018 and was launched by Alnylam immediately upon approval in the United States. Under the terms of this license agreement, we are entitled to tiered royalty payments on global net sales of ONPATTRO ranging from 1.00% - 2.33% after offsets, with the highest tier applicable to annual net sales above $500 million. This royalty interest was sold to OMERS, effective as of January 1, 2019, for $20 million in gross proceeds before advisory fees. OMERS will retain this entitlement until it has received $30 million in royalties, at which point 100% of this royalty entitlement on future global net sales of ONPATTRO will revert to us. OMERS has assumed the risk of collecting up to $30 million of future royalty payments from Alnylam and we are not obligated to reimburse OMERS if they fail to collect any such future royalties. If this royalty entitlement reverts to us, it has the potential to provide an active royalty stream or to be otherwise monetized again in full or in part.
We also have rights to a second, lower royalty interest on global net sales of ONPATTRO originating from a settlement agreement and subsequent license agreement with Acuitas.  This royalty entitlement from Acuitas has been retained by us and was not part of the royalty entitlement sale to OMERS.

Genevant Sciences, Ltd.

In April 2018, we entered into an agreement with Roivant Sciences Ltd. (“Roivant”), our largest shareholder, to launch Genevant Sciences Ltd. (“Genevant”), a company focused on the discovery, development, and commercialization of a broad range of RNA-based therapeutics enabled by Arbutus’ LNP and ligand conjugate delivery technologies. We licensed exclusive rights to our LNP and ligand conjugate delivery platforms to Genevant for RNA-based applications outside of HBV, except to the extent certain rights had already been licensed to other third parties. We retained all rights to our LNP and conjugate delivery platforms for HBV. We are entitled to receive tiered low single-digit royalties on future sales of Genevant products covered by the licensed patents. If Genevant sub-licenses the intellectual property licensed by us to Genevant, we would receive upon the commercialization of a product developed by such sub-licensee the lesser of (i) twenty percent of the revenue received by Genevant for such sublicensing and (ii) tiered low single-digit royalties on product sales by the sublicensee.

On July 23, 2020, the United States Patent and Trademark Office before the Patent Trial and Appeal Board (“PTAB”) announced their decision in Moderna Therapeutics, Inc.'s challenge of the validity of U.S. Patent 8,058,069 (“the ‘069 Patent”). In this decision, the PTAB determined no challenged claims were unpatentable. While Arbutus is the patent holder, this patent has been licensed to Genevant. The ‘069 Patent was included in this license agreement between Genevant and Arbutus.

On July 31, 2020, Roivant recapitalized Genevant through an equity investment and conversion of previously issued convertible debt securities held by Roivant. We participated in the recapitalization of Genevant with an equity investment of $2.5 million. In connection with the recapitalization, the three parties entered into an Amended and Restated Shareholders Agreement that provides Roivant with substantial control of Genevant. We have a non-voting observer seat on Genevant’s Board of Directors. As of September 30, 2020, we owned approximately 16% of the common equity of Genevant and the carrying value of our investment in Genevant was zero. Our entitlement to receive future royalties or sublicensing revenue from Genevant was not impacted by the recapitalization.

Collaboration with Assembly BioSciences, Inc.

In August 2020, the Company and Assembly entered into a clinical collaboration agreement to evaluate AB-729 in combination with Assembly’s lead HBV core inhibitor (capsid inhibitor) candidate VBR and standard-of-care Nrtl therapy for the treatment of patients with chronic HBV infection. The companies will share in the costs of the collaboration and the associated clinical trial is projected to initiate in the first half of 2021.

Research and development

Research and development expenses consist primarily of clinical and pre-clinical trial expenses, personnel expenses, consulting and third party expenses, consumables and materials, as well as a portion of stock-based compensation and general overhead costs.

Research and development expenses decreased $5.7 million and $12.2 million for the three and nine months ended September 30, 2020, respectively, as compared to the same periods in 2019. The decrease was due primarily to the October 2019 decision to discontinue development of AB-506, our prior generation capsid inhibitor product candidate, as well as higher spend on AB-729 during 2019 for preclinical studies and drug product supply in preparation for the Phase 1a/1b clinical trial which commenced in the second quarter of 2019. These decreases for the three and nine months ended September 30, 2020 were partially offset by higher spend related to AB-836, our next generation capsid inhibitor.

A significant portion of our research and development expenses are not tracked by project as they benefit multiple projects or our technology platform and because our most-advanced programs are not yet in late-stage clinical development.

General and administrative

General and administrative expenses increased $0.8 million for the three months ended September 30, 2020, as compared to the same period in 2019 due primarily to increased compensation-related expenses and an increase in insurance premiums.

26


General and administrative expenses decreased $4.7 million for the nine months ended September 30, 2020 due primarily to our former President and Chief Executive Officer's departure from the company in June 2019 and a decrease in legal fees primarily associated with the arbitration case with the University of British Columbia that was settled in September 2019. In accordance with the terms of his legacy employment agreement, our former President and Chief Executive Officer received $2.3 million of cash severance, which was paid in July 2019, and we recognized $1.1 million of non-cash stock-based compensation expense for accelerated vesting of his stock options. Partially offsetting the decreases in general and administrative expenses were increased stock-based compensation expense and an increase in insurance premiums.

Change in fair value of contingent consideration

Contingent consideration is a liability we assumed from our acquisition of Arbutus, Inc. in March 2015. In general, as time passes and assuming no changes to the assumptions related to the contingency, the fair value of the contingent consideration increases as the progress of our programs get closer to triggering contingent payments. There were no changes to the assumptions related to the contingency in 2020.

Site consolidation

As of September 30, 2020, we have recognized all of the expense related to our site consolidation.

Other income (loss)

Other income (loss) is summarized in the following table:
  Three Months Ended September 30, Nine Months Ended September 30,
  2020 2019 2020 2019
(in thousands)
Interest income $ 100  $ 503  $ 645  $ 1,709 
Interest expense (1,074) (1,100) (3,214) (1,114)
Foreign exchange (losses) / gains (19) (25) (84) 43 
Net equity investment loss (2,545) (3,512) (2,545) (11,497)
Total other loss $ (3,538) $ (4,134) $ (5,198) $ (10,859)

Interest income

The decreases in interest income for the three and nine months ended September 30, 2020, compared to the same periods in 2019 were due primarily to a general decline in market interest rates.

Interest expense

Interest expense for the three and nine months ended September 30, 2020 consisted primarily of non-cash amortization of the liability related to the sale of future royalties, which occurred in July 2019.

Foreign exchange gains (losses)

In connection with our site consolidation to Warminster, PA, our Canadian dollar denominated expenses and cash balances have decreased significantly now that a majority of our business transactions are based in the United States. We continue to incur expenses and hold some cash balances in Canadian dollars, and as such, will remain subject to risks associated with foreign currency fluctuations. In the future, we expect that the proportion of cash balances and expenses incurred in Canadian dollars, relative to U.S. dollars, will continue to decrease as a result of the site consolidation.

Equity investment losses

In the second quarter of 2018, together with Roivant, we launched Genevant, a company focused on the discovery, development, and commercialization of a broad range of RNA-based therapeutics enabled by our LNP delivery technologies. On July 31, 2020, Roivant recapitalized Genevant through an equity investment and conversion of previously issued convertible debt securities held by Roivant. We participated in the recapitalization of Genevant with an equity investment of $2.5 million. Following the recapitalization, we own approximately 16% of the common equity of Genevant. In connection with the
27


recapitalization, the three parties entered into an Amended and Restated Shareholders Agreement that provides Roivant with substantial control of Genevant. We have a non-voting observer seat on Genevant’s Board of Directors.

We determined that this $2.5 million additional investment in Genevant was funding prior losses and recorded the amount as an equity investment loss on the Condensed Consolidated Statements of Operations and Comprehensive Loss during the third quarter of 2020. For the three and nine months ended September 30, 2019, we recorded $3.5 million and $11.5 million of equity investment losses, respectively. The equity investment losses for 2019 reflected our proportionate share of Genevant’s net results on a one-quarter lag basis.

Due to our loss of significant influence with respect to Genevant as a result of the recapitalization, we discontinued the use of equity method accounting for our interest in Genevant. Following the recapitalization, we account for our interest in Genevant as equity securities without readily determinable fair values. Accordingly, an estimate of the fair value of the securities is based on the original cost less previously recognized equity method losses, less impairments, plus or minus changes resulting from future observable price changes in orderly transactions for identical or a similar Genevant securities. As of September 30, 2020, the carrying value of our investment in Genevant was zero and we owned approximately 16% of the common equity of Genevant.

Our entitlement to receive future royalties or sublicensing revenue from Genevant was not impacted by the recapitalization.


LIQUIDITY AND CAPITAL RESOURCES

The following table summarizes our cash flow activities for the periods indicated:
  Nine Months Ended September 30,
  2020 2019
(in thousands)
Net loss $ (46,703) $ (129,069)
Non-cash items 10,365  73,410 
Net change in operating items (90) (1,996)
Net cash used in operating activities (36,428) (57,655)
Net cash provided by investing activities 35,067  87,160 
Net cash provided by financing activities 66,536  23,564 
Effect of foreign exchange rate changes on cash and cash equivalents (56) 71

Cash and cash equivalents, beginning of period 31,799  36,942 
Cash and cash equivalents, end of period $ 96,918  $ 90,082 

Since our incorporation, we have financed our operations through the sales of equity, debt, revenues from research and development collaborations and licenses with corporate partners, royalty monetization, interest income on funds available for investment, and government contracts, grants and tax credits.

For the nine months ended September 30, 2020, $36.4 million of cash was used in operating activities compared to $57.7 million of cash used in the nine months ended September 30, 2019. The decrease in net cash used in operating activities was related primarily to lower research and development expenses from our decision in October 2019 to discontinue development of AB-506 as well as higher spend on AB-729 during 2019 for preclinical studies and drug product supply in preparation for the Phase 1a/1b clinical trial which commenced in the second quarter of 2019, in addition to the payment of a $5.9 million arbitration award to UBC during the nine months ended September 30, 2019.

For the nine months ended September 30, 2020, net cash provided by investing activities was $35.1 million as we purchased additional investments in marketable securities of $28.9 million, while $66.5 million of short-term investments matured. For the nine months ended September 30, 2019, net cash provided by investing activities was $87.2 million as certain short-term investments matured.

28


For the nine months ended September 30, 2020, net cash provided by financing activities was $66.5 million due primarily to proceeds from sales of common shares under our open market sale agreement, as amended, with Jefferies LLC (“Jefferies”). For the nine months ended September 30, 2019, net cash provided by financing activities was $23.6 million due primarily to proceeds from the sale of a portion of our future royalties from sales of ONPATTRO and proceeds from sales of common shares under our open market sale agreement.

Sources of Liquidity

As of September 30, 2020, we had cash, cash equivalents and investments of $118.3 million. We had no outstanding debt at September 30, 2020.

In December 2018, we entered into an Open Market Sale Agreement with Jefferies (the “Sale Agreement”), under which we could issue and sell common shares, from time to time, for an aggregate sales price of up to $50.0 million. In December 2019, we entered into an amendment to the Sale Agreement with Jefferies (the “2019 Amendment”) in connection with the filing of a shelf registration statement on Form S-3 (File No. 333-235674), filed with the SEC on December 23, 2019 (the “Shelf Registration Statement”). The 2019 Amendment revised the original Sale Agreement to reflect that we may sell our common shares, from time to time, for an aggregate sales price of up to $50.0 million, under the Shelf Registration Statement. During July 2020, we fully utilized the remaining availability under the Sale Agreement, as amended by the 2019 Amendment. In August 2020, we entered into a new amendment to the Sale Agreement (the “2020 Amendment”) with Jefferies. Pursuant to the 2020 Amendment, we can issue and sell common shares, from time to time, for an aggregate sales price of up to an additional $75.0 million under the Sale Agreement. For the three and nine months ended September 30, 2020, we issued 13,258,096 and 19,696,361 common shares, respectively, under the Sale Agreement, as amended, resulting in net proceeds of approximately $48.8 million and $66.1 million, respectively. As of September 30, 2020, there is approximately $62.3 million available under the Sale Agreement, as amended.

In August 2020, we filed a new $200 million shelf registration statement on Form S-3 (File No. 333-248467), which was declared effective by the SEC on October 22, 2020 (the “New Shelf Registration Statement”). We have not yet sold any securities under the New Shelf Registration Statement.

Additionally, we have a royalty entitlement on ONPATTRO, a drug developed by Alnylam that incorporates our LNP technology and was approved by the FDA and the EMA during the third quarter of 2018 and was launched immediately upon approval in the US. In July 2019, we sold a portion of this royalty interest to OMERS, effective as of January 1, 2019, for $20 million in gross proceeds before advisory fees. OMERS will retain this entitlement until it has received $30 million in royalties, at which point 100% of such royalty interest on future global net sales of ONPATTRO will revert to us. OMERS has assumed the risk of collecting up to $30 million of future royalty payments from Alnylam and Arbutus is not obligated to reimburse OMERS if they fail to collect any such future royalties. If this royalty entitlement reverts to us, it has the potential to provide an active royalty stream or to be otherwise monetized again in full or in part. In addition to the royalty from the Alnylam LNP license agreement, we are also receiving a second, lower royalty interest on global net sales of ONPATTRO originating from a settlement agreement and subsequent license agreement with Acuitas. The royalty from Acuitas has been retained by us and was not part of the royalty sale to OMERS.

In October 2017, we closed the sale of 500,000 Series A participating convertible preferred shares (the “Preferred Shares”) to Roivant for gross proceeds of $50.0 million. A second tranche of 664,000 Preferred Shares for gross proceeds of $66.4 million closed in January 2018, following receipt of the approval of our shareholders. We are using these proceeds to develop and advance product candidates through clinical trials, as well as for working capital and general corporate purposes.

Cash requirements

At September 30, 2020, we held an aggregate of $118.3 million in cash, cash equivalents and investments. We believe that our cash, cash equivalents and investments as of September 30, 2020 is sufficient to fund our operations into mid-2022. In the future, substantial additional funds will be required to continue with the active development of our pipeline products and technologies.

In particular, our funding needs may vary depending on a number of factors including:

the effects of the COVID-19 pandemic on our business, the medical community and the global economy;
revenue earned from our legacy collaborative partnerships and licensing agreements, including potential royalty payments from Alnylam’s ONPATTRO;
revenue earned from ongoing collaborative partnerships, including milestone and royalty payments;
the extent to which we continue the development of our product candidates, add new product candidates to our pipeline, or form collaborative relationships to advance our product candidates;
delays in the development of our product candidates due to pre-clinical and clinical findings;
our decisions to in-license or acquire additional products, product candidates or technology for development, in particular for our HBV therapeutics programs;
our ability to attract and retain corporate partners, and their effectiveness in carrying out the development and ultimate commercialization of our product candidates;
whether batches of drugs that we manufacture fail to meet specifications resulting in delays and investigational and remanufacturing costs;
the decisions, and the timing of decisions, made by health regulatory agencies regarding our technology and products;
competing technological and market developments; and
costs associated with prosecuting and enforcing our patent claims and other intellectual property rights, including litigation and arbitration arising in the course of our business activities.

We intend to seek funding to maintain and advance our business from a variety of sources including public or private equity or debt financing, potential monetization transactions, collaborative or licensing arrangements with pharmaceutical companies and government grants and contracts. There can be no assurance that funding will be available at all or on acceptable terms to permit further development of our research and development programs. Further, the continued spread of COVID-19 has also led to severe disruption and volatility in the global capital markets, which could increase our cost of capital and adversely affect our ability to access the capital markets in the future. 

If adequate funding is not available, we may be required to delay, reduce or eliminate one or more of our research or development programs or reduce expenses associated with our non-core activities. We may need to obtain funds through arrangements with collaborators or others that may require us to relinquish most or all of our rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise seek if we were better funded. Insufficient financing may also mean failing to prosecute our patents or relinquishing rights to some of our technologies that we would otherwise develop or commercialize.

OFF-BALANCE SHEET ARRANGEMENTS

We do not have any off-balance sheet arrangements 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 that is material to investors.

ITEM 3.      QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes in our quantitative and qualitative disclosures about market risk from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019.

ITEM 4.      CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

30


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 September 30, 2020. The term “disclosure controls and procedures”, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure, particularly during the period in which this Quarterly Report on Form 10-Q was being prepared. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their desired objectives, and our 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 September 30, 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 have been no changes in our internal control over financial reporting (as defined in Rules 13a–15(f) and 15d–15(f) under the Exchange Act) during the three months ended September 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 1.       LEGAL PROCEEDINGS

For other information regarding legal matters, please refer to note 8. Contingencies and Commitments to the condensed consolidated financial statements contained in Part I of this Quarterly Report on Form 10-Q, which is incorporated herein by reference.
Moderna Inter Partes Review Petitions

On February 21, 2018 and on March 5, 2018, Moderna Therapeutics, Inc. (“Moderna”) filed petitions requesting the United States Patent and Trademark Office to institute an Inter Partes Review of Arbutus United States Patents 9,404,127 (“’127 patent”) and 9,364,435 (“’435 patent”), respectively. In its petitions, Moderna sought to invalidate all claims of each Arbutus patent based on Moderna’s allegation that the claims are anticipated and/or obvious. Arbutus filed a response to Moderna’s petitions on June 14, 2018. On September 12, 2018, the Patent Trial and Appeal Board (“PTAB”) rendered its decision to institute Inter Partes Review of both challenged patents. Arbutus’ response was provided December 21, 2018. Oral hearing took place on June 6, 2019. On September 10, 2019, the PTAB rendered its decision on the ‘127 patent, holding all claims invalid as anticipated and on September 11, 2019, the PTAB rendered its decision on the ‘435 patent, holding certain claims invalid and upholding other claims as valid. On February 27, 2020, the Federal Circuit vacated the ‘127 IPR decision and remanded it back to the PTAB for rehearing, where it is presently being held in abeyance until the Supreme Court acts on a petition for writ of certiorari filed July 23, 2020 in a different case. On October 13, 2020, the Supreme Court granted certiorari in United States v. Athrax, Inc. which was the basis of the Federal Circuit’s remand in the ‘127 IPR. On November 27, 2019, Moderna and Arbutus both appealed the ‘435 IPR decision. Moderna filed its opening brief on May 4, 2020. Arbutus’ opening and responsive brief was provided on July 27, 2020. Moderna filed its reply and responsive brief on October 5, 2020.

On January 9, 2019, Moderna filed an additional petition requesting Inter Partes Review of Arbutus United States Patent 8,058,069 (“’069 patent”). The PTAB instituted Inter Partes Review of the ‘069 patent on July 24, 2019, with a hearing held on April 22, 2020. On July 23, 2020, the PTAB rendered its decision on the ‘069 patent, upholding all claims as valid. On September 23, 2020, Moderna appealed the ‘069 IPR decision.

Moderna and Merck European Oppositions

On April 5 2018, Moderna and Merck, Sharp & Dohme Corporation (“Merck”) filed Notices of Opposition to Arbutus’ European patent EP 2279254 (“’254 patent”) with the European Patent Office (“EPO”), requesting that the patent be revoked in its entirety for all contracting states. Arbutus filed a response to Moderna and Merck’s oppositions on September 3, 2018. A hearing was conducted before the Opposition Division on October 10, 2019. At the conclusion of the hearing, the EPO upheld an auxiliary request adopting the amendment, as put forth by Arbutus, of certain claims of the ‘254 patent. In February 2020 Moderna and Merck filed Notices of Appeal challenging the EPO’s grant of the auxiliary request. Merck filed its notice of appeal on February 24, 2020 and Moderna on February 27, 2020. Arbutus’ response was filed on September 8, 2020.

ITEM 1A.    RISK FACTORS

The COVID-19 coronavirus could adversely impact our business, including our clinical development plans.

In December 2019, a novel strain of coronavirus, COVID-19, was reported to have surfaced in Wuhan, China. Since then, the COVID-19 coronavirus has spread to multiple countries, including the United States, and has caused significant disruptions around the world. We may experience other disruptions as a result of the COVID-19 pandemic that could severely impact our business, including:
interruption of key manufacturing, research and clinical development activities due to limitations on work and travel imposed or recommended by federal or state governments, employers and others;
delays or difficulties in clinical trial site operations, including difficulties in recruiting clinical site investigators and clinical site staff and difficulties in enrolling patients or treating patients in active trials;
interruption of key business activities due to illness and/or quarantine of key individuals and delays associated with recruiting, hiring and training new temporary or permanent replacements for such key individuals, both internally and at our third party service providers;
delays in research and clinical trial sites receiving the supplies and materials needed to conduct preclinical studies and clinical trials, due to work stoppages, travel and shipping interruptions or restrictions or other reasons;
32


difficulties in raising additional capital needed to pursue the development of our programs due to the slowing of our economy and near term and/or long term negative effects of the pandemic on the financial, banking and capital markets;
changes in local regulations as part of a response to the COVID-19 coronavirus outbreak that may require us to change the ways in which research, including clinical development, is conducted, which may result in unexpected costs; and
delays in necessary interactions with regulators and other important agencies and contractors due to limitations in employee resources, travel restrictions or forced furlough of government employees.
 
The global outbreak of the COVID-19 coronavirus continues to rapidly evolve. The extent to which the COVID-19 coronavirus may impact our business will depend on future developments, which 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 social distancing 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 virus.

There have been no other material changes in our risk factors from those disclosed in our Annual Report on Form 10-K for the fiscal year-ended December 31, 2019.
