CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q includes “forward-looking statements” within the meaning of the U.S. Private Securities Litigation Reform Act of 1995 and “forward-looking information” within the meaning of Canadian securities laws, or collectively, forward-looking statements. Forward-looking statements include statements that may relate to our plans, objectives, goals, strategies, future events, future revenue or performance, capital expenditures, financing needs and other information that is not historical information. Many of these statements appear, in particular, under the headings “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations”. Forward-looking statements can often be identified by the use of terminology such as “subject to”, “believe,” “anticipate,” “plan,” “expect,” “intend,” “estimate,” “project,” “may,” “will,” “should,” “would,” “could,” “can,” the negatives thereof, variations thereon and similar expressions, or by discussions of strategy. In addition, any statements or information that refer to expectations, beliefs, plans, projections, objectives, performance or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking. In particular, these forward-looking statements include, but are not limited to:

the size of our addressable markets and our ability to commercialize product candidates;
the achievement of advances in and expansion of our therapeutic platforms and antibody engineering expertise;
the likelihood of product candidate development and clinical trial progression, initiation or success;
our ability to predict and manage government regulation; and
the impact of the COVID-19 pandemic on our business and operations.

All forward-looking statements, including, without limitation, those related to our examination of historical operating trends, are based upon our current expectations and various assumptions. Certain assumptions made in preparing the forward-looking statements include:

our ability to manage our growth effectively;
the absence of material adverse changes in our industry or the global economy;
our ability to understand and predict trends in our industry and markets;
our ability to maintain good business relationships with our strategic partners;
our ability to comply with current and future regulatory standards;
our ability to protect our intellectual property rights;
our continued compliance with third-party license terms and the non-infringement of third-party intellectual property rights;
our ability to manage and integrate acquisitions;
our ability to retain key personnel; and
our ability to raise sufficient debt or equity financing to support our continued growth.

We believe there is a reasonable basis for our expectations and beliefs, but they are inherently uncertain. We may not realize our expectations, and our beliefs may not prove correct. Actual results could differ materially from those described or implied by such forward-looking statements. The following uncertainties and factors, among others (including those set forth under “Risk Factors”), could affect future performance and cause actual results to differ materially from those matters expressed in or implied by forward-looking statements:

our ability to obtain regulatory approval for our product candidates without significant delays;
the predictive value of our current or planned clinical trials;
delays with respect to the development and commercialization of our product candidates, which may cause increased costs or delay receipt of product revenue;
our, or any of our partners’, ability to enroll subjects in clinical trials and thereby complete trials on a timely basis;
the design or our execution of clinical trials may not support regulatory approval, including where clinical trials are conducted outside the United States;
the extent to which our business may be adversely affected by the COVID-19 pandemic;

our ability to comply with procedural and administrative requirements relating to our patents;
the risk of claims challenging the inventorship of our patents and other intellectual property;

we will require FDA approval for any proposed product candidate names and any failure or delay associated with such approval may adversely affect our business;
the risk of employee misconduct including noncompliance with regulatory standards and insider trading;
our ability to market our products in a manner that does not violate the law and subject us to civil or criminal penalties;
if we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected;
our ability to retain key executives and attract and retain qualified personnel;
our ability to manage organizational growth;
our exposure to potential securities class action litigation; and
if securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our share price and trading volume could decline.

Consequently, forward-looking statements should be regarded solely as our current plans, estimates and beliefs. You should not place undue reliance on forward-looking statements. We cannot guarantee future results, events, levels of activity, performance or achievements. We do not undertake and specifically decline any obligation to update, republish or revise forward-looking statements to reflect future events or circumstances or to reflect the occurrences of unanticipated events, except as required by law.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report on Form 10-Q, and although we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted a thorough inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and you are cautioned not to unduly rely upon these statements.

Notes to the Interim Condensed Consolidated Financial Statements
(unaudited)
(Expressed in thousands of U.S. dollars except share and per share data)

1. Nature of Operations
Zymeworks Inc. (the “Company” or “Zymeworks”) is a clinical-stage biopharmaceutical company dedicated to the development of next-generation multifunctional biotherapeutics. Zymeworks was incorporated on September 8, 2003 under the laws of the Canada Business Corporations Act. On October 22, 2003, the Company was registered as an extra-provincial company under the Company Act (British Columbia). On May 2, 2017, the Company continued under the Business Corporations Act (British Columbia).
Since its inception, the Company has devoted substantially all of its resources to research and development activities, including developing its therapeutic platforms, and identifying and developing potential product candidates by undertaking preclinical studies and clinical trials. The Company supports these activities through general and administrative support, as well as by raising capital, conducting business planning and protecting its intellectual property.
2. Summary of Significant Accounting Policies
Basis of Presentation
The accompanying interim condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC for interim financial information. Accordingly, these financial statements do not include all the information and footnotes required for complete financial statements and should be read in conjunction with the audited consolidated financial statements of the Company and the accompanying notes thereto for the year ended December 31, 2020.
These unaudited interim condensed consolidated financial statements reflect all adjustments, consisting solely of normal recurring adjustments, which, in the opinion of management, are necessary for a fair presentation of results for the interim periods presented. The results of operations for the three and six months ended June 30, 2021 and 2020 are not necessarily indicative of results that can be expected for a full year. These unaudited interim 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, 2020.
All amounts expressed in the interim condensed consolidated financial statements of the Company and the accompanying notes thereto are expressed in thousands of U.S. dollars, except for share and per share data and where otherwise indicated. References to “$” are to U.S. dollars and references to “C$” are to Canadian dollars.
Certain prior period amounts have been reclassified from general and administrative expenses to research and development expenses to conform to the current period's presentation. These reclassifications had no effect on previously reported operating expenses, net loss, shareholders equity and cash flows from operating activities.

Use of Estimates
The preparation of consolidated financial statements in accordance with U.S. GAAP requires the Company to make estimates and judgments in certain circumstances that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, most notably those related to revenue recognition including estimated timing of completion of performance obligations required to meet revenue recognition criteria, accrual of expenses including clinical and preclinical study expense accruals, stock-based compensation, valuation allowance for deferred taxes, benefits under the Scientific Research and Experimental Development (“SR&ED”) program, and other contingencies. Management bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ from these estimates.
The full extent to which the COVID-19 pandemic may directly or indirectly impact the Company’s business, results of operations and financial condition, including revenues, expenses, clinical trials, research and development costs and employee-related amounts, will depend on future developments that are evolving and highly uncertain, such as the duration and severity of outbreaks, including potential future waves or cycles, and the effectiveness of actions taken to contain and treat COVID-19. The Company considered the potential impact of COVID-19 when making certain estimates and judgments relating to the preparation

of these consolidated financial statements. While there was no material impact to the Company’s consolidated financial statements as of and for the three and six months ended June 30, 2021, the Company’s future assessment of the magnitude and duration of COVID-19, as well as other factors, could result in a material impact to the Company’s consolidated financial statements in future reporting periods.
3. Recent Accounting Pronouncements

The Company has reviewed recent accounting pronouncements and concluded that they are either not applicable to the business, or that no material effect is expected on the consolidated financial statements as a result of future adoption.

6. IPR&D and Goodwill
Acquired IPR&D
In-process research and development assets (“IPR&D”) acquired in the 2016 Kairos Therapeutics Inc. (“Kairos”) business combination are classified as indefinite-lived intangible assets and are not currently being amortized. The carrying value of IPR&D, net of impairment was $17,628 at both June 30, 2021 and December 31, 2020.

Goodwill
The Company performed its most recent annual impairment test of goodwill as of December 31, 2020. As part of the evaluation of the recoverability of goodwill, the Company identified only one reporting unit to which the total carrying amount of goodwill has been assigned. As at December 31, 2020, the Company performed a qualitative assessment for its annual impairment test of goodwill after concluding that it was not more likely than not that the fair value of the reporting unit was less than its carrying value. Consequently, a quantitative impairment test was not required. The Company concluded that there were no impairment indicators related to goodwill as of June 30, 2021.

Table of Contents
d.Pre-Funded Common Share Warrants
In connection with a public offering completed on June 24, 2019, the Company issued 4,166,690 Pre-Funded Warrants at a price of $17.9999 per Pre-Funded Warrant which granted holders of warrants the right to purchase up to 4,166,690 common shares of the Company, at an exercise price of $0.0001 per share.
In connection with a public offering completed on January 27, 2020 (note 8a), the Company issued 1,075,271 Pre-Funded Warrants at a price of $46.4999 per Pre-Funded Warrant which granted holders of warrants the right to purchase up to 1,075,271 common shares of the Company, at an exercise price of $0.0001 per share.
The Pre-Funded Warrants are exercisable by the holders at any time on or after the original issue date. The Pre-Funded Warrants do not expire unless they are exercised or settled in accordance with the Pre-Funded Warrant agreement. As the Pre-Funded Warrants meet the condition for equity classification, proceeds from issuance of the Pre-Funded Warrants, net of any transaction costs, are recorded in additional paid-in capital. Upon exercise of the Pre-Funded Warrants, the historical costs recorded in additional paid-in capital along with exercise price collected from holders will be recorded in common shares. No Pre-Funded Warrants have been exercised to date.
e.Stock-Based Compensation
Original Stock Option Plan
On July 14, 2006, the shareholders of the Company approved an employee stock option plan (the “Original Plan”). The Original Plan provides for the granting of options to directors, officers, employees and consultants. Options to purchase common shares may be granted at an exercise price of each option equal to the last private issuance of common shares immediately preceding the date of the grant. The total number of options outstanding is not to exceed 20% of the issued common shares of the Company.
Options granted under the Original Plan are exercisable at various dates over their 10-year life. Common shares are issued from treasury when options are exercised.
Options issued to employees under the Original Plan vest over 4 years, with 25% of the options subject to vesting one year after grant and the remainder of the options vesting monthly over the following three years in equal installments. Options issued to directors under the Original Plan vest over 3 years in equal monthly installments, and options issued to consultants and members of the Scientific Advisory Board under the Original Plan vest immediately upon issuance.
The exercise prices of the Company’s stock options under the Original Plan are denominated in Canadian dollars. The Canadian dollar amounts have been translated to U.S. dollars using the period end rate or the average foreign exchange rate for the period, as applicable, and have been provided for information purposes. Upon the effectiveness of the Company’s New Stock Option Plan described below, no further options were issuable under the Original Plan. However, all outstanding options granted under the Original Plan remain outstanding, subject to the terms of the Original Plan and the applicable grant documents, until such outstanding options are exercised or they terminate or expire by their terms.
New Stock Option and Equity Compensation Plan
On April 10, 2017, the Company’s shareholders approved a new stock option plan, which became effective immediately prior to the consummation of the Company's IPO. This plan allows for the grant of options to directors, officers, employees and consultants in U.S. or Canadian dollars, and also permits the Company to grant incentive stock options (“ISOs”), within the meaning of Section 422 of the Internal Revenue Code, to its employees. On June 7, 2018, the Company’s shareholders approved an amendment and restatement of this plan (this plan, as amended and restated, the “New Plan”), which was further amended on March 4, 2020, that includes an article that allows the Company to grant restricted shares, restricted share units (“RSUs”) and other share-based awards, in addition to stock options. The terms and vesting provisions of options to be granted under the New Stock Option Plan remained same as the Original Stock Option Plan.
The maximum number of common shares reserved for issuance under the New Plan is 10,698,103, which includes 7,671,197 shares issuable upon exercise of options outstanding as of June 30, 2021. Beginning in 2021 and ending in 2028, this maximum number may be increased on the first day of each calendar year by up to 4.0% of the number of outstanding shares on the last day of the immediately preceding calendar year. ISOs may be granted with respect to a maximum fixed amount equal to 20% of the shares reserved for issuance under the New Plan as of June 7, 2018.

Restricted Stock Units (RSUs)
During the six months ended June 30, 2021, the Company granted 122,860 RSUs to certain employees that vest over a period of three years, in the amount of one-third each year on the anniversary of the grant date. RSUs are equity-settled on each vesting date, subject to the grantee’s continued employment with the Company on the vesting date. The fair value of RSUs granted was calculated by using the closing stock price on the grant date. As of June 30, 2021, there was $4,191 of unamortized RSU expense that will be recognized over a weighted average period of 1.68 years.

Stock Options
All options granted under the New Plan will have an exercise price determined and approved by the Board of Directors on the date of the grant, which shall not be less than the market price of the common shares at such time. For the purposes of the New Plan, the market price of a common share shall be the closing sale price of a share on the grant date reported by the stock exchange with the greatest trading volume or, if such day is not a trading day, the closing sale price reported for the immediately preceding trading day. The Company may convert a market price denominated in Canadian dollars into United States dollars and vice versa and such converted amount shall be the market price.
An option shall be exercisable during a period established by the Board of Directors which shall commence on the date of the grant and shall terminate not later than ten years after the date of the granting of the option. The New Plan provides that the exercise period shall automatically be extended if the date on which it is scheduled to terminate shall fall during a black-out period. In such cases, the extended exercise period shall terminate on the tenth business day after the last day of the black-out period, provided that the exercise period shall in no case be extended beyond the tenth anniversary of the date the option was granted. All options shall vest in accordance with the terms of their grant agreements.

Expected Volatility — Volatility is a measure of the amount by which a financial variable such as a share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. As the Company does not yet have sufficient history of its own volatility, the Company has identified several public entities of similar complexity and stage of development and calculates historical volatility using the volatility of these companies.
Risk-Free Interest Rate — This rate is from the Government of Canada and U.S. Federal Reserve marketable bonds for the month prior to each option grant during the year, having a term that most closely resembles the expected life of the option.
Expected Term — This is the period of time that the options granted are expected to remain unexercised. Options granted have a maximum term of ten years. The Company uses the simplified method to calculate the average expected term, which represents the average of the vesting period and the contractual term.
Share Fair Value — Options granted after the Company’s IPO, are issued with exercise price equal to the fair market value of the Company’s stock on the date the grant is approved by the Board of Directors. Before the IPO, the Company granted stock options at exercise prices not less than the fair value of its common shares as determined by the Board of Directors, with input from management. Management estimated the fair value of its common shares based on a number of objective and subjective factors, including the most recently available valuation of common shares prepared by independent valuation specialists, external market considerations affecting the biotechnology industry and the historic prices at which the Company sold common shares.
The weighted-average Black-Scholes option pricing assumptions for liability classified stock options outstanding at June 30, 2021 and 2020 are as follows:

At June 30, 2021, the unamortized compensation expense related to unvested options was $49,929 (C$62,016). The remaining unamortized compensation expense as of June 30, 2021 will be recognized over a weighted-average period of 1.87 years.
f.Employee Stock Purchase Plan:
On April 10, 2017, the Company’s shareholders approved an employee stock purchase plan (“ESPP”) which became effective immediately prior to the consummation of the Company’s IPO. On June 7, 2018, certain amendments to the ESPP were approved by shareholders. Prior to these amendments, the ESPP allowed eligible employees to acquire common shares at a discounted purchase price of 85% of the market value of the Company's common shares on the purchase date. The ESPP, as amended, allows eligible employees to acquire common shares at a discounted purchase price of the lesser of (i) 85% of the market price of a common share on the first day of the applicable purchase period and (ii) 85% of the market price of a common share on the purchase date. The ESPP qualifies as an “employee stock purchase plan” within the meaning of Section 423 of the Code for employees who are United States taxpayers.
The Company currently holds offerings consisting of a single six-month purchase period commencing on January 1 and July 1 of each calendar year, with a single purchase date at the end of the purchase period on June 30 and December 31 of each calendar year.
12

Table of Contents
Eligible employees are able to contribute up to 15% of their gross base earnings for purchases under the ESPP through regular payroll deductions. Purchases of shares under the ESPP are limited for each employee at $25 thousand worth of the Company’s common shares (determined using the lesser of (i) the market price of a common share on the first day of the applicable purchase period and (ii) the market price of a common share on the purchase date) for each year such purchase right is outstanding.
As this plan is considered compensatory, the Company recognizes compensation expense on these awards based on their estimated grant date fair value using the Black-Scholes option pricing model. The Company recognizes compensation expense in the consolidated statements of loss and comprehensive loss on a straight-line basis over the requisite service period. For the six months ended June 30, 2021, the Company recorded compensation expense of and $518 (six months ended June 30, 2020: $311) in research and development expense and general and administrative expense accounts. As of June 30, 2021, the total amount contributed by ESPP participants and not yet settled is $1,296 (December 31, 2020: $926).

Since December 31, 2020, there have not been any material changes to the key terms of the Company's collaboration and license agreements. For further information on the terms and conditions of the Company's existing collaboration and license agreements, please refer to the notes to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year-ended December 31, 2020.
In June 2020, the Company's existing collaboration agreement with BMS was amended to expand the license grant to include the use of the Company's EFECT platform for the development of product candidates and to extend the research term. The amendment included an upfront fee of $12,000 and all other financial terms were unchanged. The Company's performance obligations in relation to the upfront fee were met on the date of amendment. Accordingly, the upfront payment was recognized as revenue during the six months ended June 30, 2020.
In March 2020, the Company recognized milestone revenue of $5,000 under a license and collaboration agreement with BeiGene upon BeiGene's dosing of zanidatamab in the first patient in a clinical study in its territory. The Company did not have any performance obligations in relation to this milestone on the date it was achieved. Accordingly, it was recognized as revenue during the six months ended June 30, 2020.

At June 30, 2021, contract assets from research, collaboration and licensing agreements were nil (December 31, 2020: nil) and contract liabilities were $32,941 (December 31, 2020: $32,941). Contract liabilities include deferred revenue relating to an upfront payment received in 2018 under the licensing and collaboration agreement with BeiGene referred to above. During the six months ended June 30, 2021, the Company did not recognize any revenue from performance obligations satisfied in relation to the deferred revenue (six months ended June 30, 2020: nil). Amounts not expected to be recognized as revenue in the next twelve months from June 30, 2021 have been classified as long-term deferred revenue.

11. Leases

The Company leases separate office and laboratory spaces in Vancouver, British Columbia, with terms of each lease expiring in February 2022. On January 25, 2019, the Company entered into a lease for a new building in Vancouver to serve as the Company’s future headquarters, including both office and laboratory space. This lease commenced for accounting purposes in May 2021 and construction of leasehold improvements is in progress. This lease has an initial term of ten years, with two five-year extension options. In addition, the Company leases office space in Seattle, Washington with lease terms expiring in February 2027. None of the optional extension periods have been included in the determination of the right-of-use assets or the lease liabilities for operating leases as the Company did not consider it reasonably certain that the Company would exercise any such options. The Company also leases office equipment under capital lease agreements.
The balance sheet classification of the Company’s lease liabilities was as follows:

During the six months ended June 30, 2021, the Company incurred total operating lease expenses of $2,378, which included lease expenses associated with fixed lease payments of $2,176, and variable payments associated with common area maintenance and similar expenses of $202.
In addition to the operating lease liabilities included in the table above, the Company has commitments for future operating lease payments of $3,922 under the terms of the lease for the Company’s additional lab space in Seattle, which is expected to commence in November 2021.
12. Financial Instruments
The Company evaluates financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level of classification each reporting period. This determination requires the Company to make subjective judgments as to the significance of inputs used in determining fair value and where such inputs lie within the fair value hierarchy.

Fair Value Measurements
The Company measures certain financial instruments and other items at fair value.
To determine fair value, the Company uses a fair value hierarchy that prioritizes the inputs, assumptions and valuation techniques used to measure fair value. The three levels of the fair value hierarchy are as follows:
Level 1 inputs are unadjusted quoted market prices for identical instruments available in active markets.
Level 2 inputs are inputs other than Level 1 prices, such as prices for a similar asset or liability that are observable 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.
Level 3 inputs are unobservable inputs for the asset or liability and will reflect management’s assessment 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 Company’s financial instruments consist of cash and cash equivalents, short-term and long-term investments in marketable and other securities, amounts receivable, accounts payable and accrued liabilities, finance and operating lease obligations, and other long-term liabilities.

The carrying values of cash and cash equivalents, short-term investments in marketable securities, amounts receivable and accounts payable and accrued liabilities approximate their fair values due to the near-term maturities of these financial instruments. As at June 30, 2021, long-term investments in equity securities of private entities are accounted for as available for

sale at their fair values. Other long-term liabilities for contingent consideration related to business acquisitions are recorded at fair value on the acquisition date and are adjusted quarterly for changes in fair value. Changes in the fair value of contingent consideration liabilities can result from changes in anticipated milestone payments and changes in assumed discount periods and rates. These inputs are unobservable in the market and therefore categorized as level 3 inputs as defined above.

The following tables present information about the Company’s liabilities that are measured at fair value on a recurring basis, and indicate the fair value hierarchy of the valuation techniques used to determine such fair value:

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents, short-term investments, long-term investments and accounts receivable. Cash and cash equivalents and investments in marketable securities are invested in accordance with the Company’s cash investment policy with the primary objective being the preservation of capital and maintenance of liquidity. The cash investment policy includes guidelines on the quality of financial instruments and defines allowable investments that the Company believes minimizes the exposure to concentration of credit risk. The Company limits its exposure to credit loss by placing its cash and cash equivalents and short-term investments with high credit quality financial institutions.

At June 30, 2021, the maximum exposure to credit risk for accounts receivable was $9,160 (December 31, 2020: $15,293) and all accounts receivable are due within the next 12 months. As at June 30, 2021, accounts receivable included $3,598 in lease incentive receivable in relation to the lease for the Company’s future headquarters (December 31, 2020: nil). As at June 30, 2021 and December 31, 2020, the Company has not recognized any provision for expected credit losses in relation to accounts receivable.

Liquidity Risk
Liquidity risk is the risk that the Company will encounter difficulty in meeting the obligations associated with its financial liabilities that are settled by delivering cash or another financial asset. The Company’s short-term cash requirements are primarily to settle its financial liabilities, which consist primarily of accounts payable and accrued liabilities falling due within 45 days and current portion of lease obligations falling due within the next 12 months, with medium-term requirements to invest in property and equipment and research and development. The Company’s principal sources of liquidity to settle its financial liabilities are cash, cash equivalents and short-term investments, collection of accounts receivable relating to research collaboration and license agreements and additional public equity offerings as required. The Company believes that these principal sources of liquidity are sufficient to fund its operations for at least the next 12 months.

Foreign Currency Risk

The Company incurs certain operating expenses in currencies other than the U.S. dollar and accordingly is subject to foreign exchange risk due to fluctuations in exchange rates. The Company does not use derivative instruments to hedge exposure to foreign exchange risk due to the low volume of transactions denominated in foreign currencies. At June 30, 2021, the Company’s net monetary assets denominated in Canadian dollars were $16,580 (C$20,650).

The operating results and financial position of the Company are reported in U.S. dollars in the Company’s consolidated financial statements. The fluctuation of the U.S. dollar relative to the Canadian dollar and other foreign currencies will have an impact on the reported balances for net assets, net loss and shareholders’ equity in the Company’s consolidated financial statements.
13. Commitments and Contingencies
Commitments
The Company has entered into research collaboration agreements with strategic partners in the ordinary course of operations that may include contractual milestone payments related to the achievement of pre-specified research, development, regulatory and commercialization events and indemnification provisions, which are common in such agreements. Pursuant to the agreements, the Company is obligated to make research and development and regulatory milestone payments upon the occurrence of certain events and royalty payments based on net sales. The maximum amount of potential future indemnification is unlimited, however, the Company currently holds commercial and product liability insurance that limits the Company’s liability and may enable it to recover a portion of any future amounts paid. Historically, the Company has not made any indemnification payments under such agreements and believes that the fair value of these indemnification obligations is minimal. Accordingly, the Company has not recognized any liabilities relating to indemnification obligations for any period presented in the consolidated financial statements.
In connection with the Company's 2016 Kairos acquisition, the Company may be required to make future payments to CDRD Ventures Inc. (“CVI”) upon the direct achievement of certain development milestones for products incorporating certain Kairos intellectual property, as well as royalty payments on the net sales of such products. For out-licensed products and technologies incorporating certain Kairos intellectual property, the Company may be required to pay CVI a mid-single digit percentage of the future revenue as a result of a revenue sharing agreement. As of June 30, 2021, the contingent consideration had an estimated fair value of $1,316, which has been recorded within other long-term liabilities on the Company's consolidated balance sheet (December 31, 2020: $1,285). The contingent consideration was calculated using a probability weighted assessment of the likelihood of the milestones being met, a probability adjusted discount rate that reflects the stage of the development and time to complete the development. Contingent consideration is a financial liability and measured at its fair value at each reporting period, with any changes in fair value from the previous reporting period recorded in the statement of loss and comprehensive loss.
Contingencies
From time to time, the Company may be subject to various legal proceedings and claims related to matters arising in the ordinary course of business. The Company does not believe it is currently subject to any material matters where there is at least a reasonable possibility that a material loss may be incurred.

Overview

Zymeworks is a clinical-stage biopharmaceutical company dedicated to the development of next-generation multifunctional biotherapeutics. Our suite of complementary therapeutic platforms and our fully integrated drug development engine provide the flexibility and compatibility to precisely engineer and develop highly differentiated product candidates. These capabilities have resulted in multiple product candidates with the potential to drive positive outcomes in large underserved and unaddressed patient populations.
Our lead product candidate, zanidatamab (formerly known as ZW25), is a novel bispecific antibody that targets two distinct domains of the human epidermal growth factor receptor 2 (“HER2”). The unique mechanism of action of zanidatamab may enable it to address unmet need in patient populations with HER2-expressing cancers, including those with lower levels of expression, for which there are no approved HER2-targeted agents. In clinical trials, monotherapy zanidatamab and zanidatamab in combination with chemotherapy have been well tolerated with promising antitumor activity in patients with heavily pretreated HER2-expressing cancers that have progressed after having received standard of care, including multiple HER2-targeted regimens. Based on these data, we initiated a number of global multicenter clinical trials to evaluate zanidatamab in specific indications and lines of therapy. These include (i) a pivotal trial in patients with previously treated HER2 gene amplified biliary tract cancer (“BTC”), (ii) the first-line treatment of HER2-positive metastatic gastroesophageal adenocarcinomas (“GEA”), BTC, or colorectal cancer in combination with standard of care chemotherapy, (iii) previously-treated locally advanced and/or metastatic HER2-positive, hormone receptor-positive breast cancer in combination with Pfizer’s Ibrance (palbociclib) and fulvestrant, and (iv) previously-treated locally advanced and/or metastatic HER2-expressing breast cancer in combination with Seagen, Inc.’s (“Seagen”) Tukysa (tucatinib) and chemotherapy. Our partner, BeiGene, Ltd. (“BeiGene”), has initiated Phase 1b/2 clinical trials evaluating zanidatamab for (i) the first-line treatment of metastatic HER2-positive breast cancer in combination with docetaxel and for (ii) the first-line treatment of metastatic HER2-positive GEA in combination with tislelizumab and chemotherapy. In addition, zanidatamab continues to be evaluated in several indications including colorectal, endometrial and other HER2-expressing cancers.
Our second product candidate, ZW49, combines the unique design of zanidatamab with our ZymeLink antibody-drug conjugate (“ADC”) platform, comprised of our proprietary cytotoxin (cancer cell-killing compound) and cleavable linker. We designed ZW49 to be a best-in-class HER2-targeting ADC to further address unmet need across a range of HER2-expressing cancers. A Phase 1 clinical trial to establish safety and antitumor activity of ZW49 began in 2019.
We are also advancing a deep pipeline of preclinical product candidates and discovery-stage programs in oncology (including immuno-oncology (“I-O”) agents) and other therapeutic areas.
Our proprietary capabilities and technologies include several modular, complementary therapeutic platforms that can be used in combination with each other and with existing approaches. This ability to layer technologies without compromising manufacturability enables us to engineer next-generation biotherapeutics with synergistic activity, which we believe will result in improved patient outcomes. Our core platforms include:

Azymetric, our bispecific platform, which enables therapeutic antibodies to simultaneously bind multiple distinct locations on a target (known as an epitope) or to multiple targets. This is achieved by tailoring multiple configurations of the antibody’s Fab regions (locations on the antibody to which epitopes bind);
18

Table of Contents
ZymeLink, our ADC platform, comprised of cytotoxins and the linker technology used to couple these cytotoxins to tumor-targeting antibodies or proteins. This platform can be used in conjunction with our other therapeutic platforms to increase safety and efficacy as compared to existing ADC technologies;
EFECT, which enables finely tuned modulation (both up and down) of immune cell recruitment and function; and
ProTECT, which enables tumor-specific activity that may reduce systemic toxicity, and simultaneously enhances localized immune co-stimulation or checkpoint modulation that may increase efficacy.

Our protein engineering expertise and proprietary structure-guided molecular modeling capabilities enable these therapeutic platforms. Together with our internal antibody discovery and generation technologies, we have established a fully integrated drug development engine and toolkit capable of rapidly delivering a steady pipeline of next-generation product candidates in oncology and other therapeutic areas.
Our Azymetric, EFECT and ZymeLink therapeutic platforms have been further leveraged through multiple revenue-generating strategic partnerships with the following global pharmaceutical companies: Merck Sharp & Dohme Research GmbH (“Merck”), Eli Lilly and Company (“Lilly”), Celgene Corporation and Celgene Alpine Investment Co. LLC (formerly “Celgene” and now a Bristol-Myers Squibb company, “BMS”), GlaxoSmithKline Intellectual Property Development Limited (“GSK”), Daiichi Sankyo Co., Ltd. (“Daiichi Sankyo”), Janssen Biotech, Inc. (“Janssen”), LEO Pharma A/S (“LEO”), BeiGene, and Iconic Therapeutics, Inc. (“Iconic”).
Our goal is to leverage our next-generation therapeutic platforms and proprietary protein engineering capabilities to become a domain dominator in the discovery, development and commercialization of best-in-class multifunctional biotherapeutics for the treatment of cancer and other diseases with high unmet medical need.
We commenced operations in 2003 and have since devoted substantially all of our resources to research and development activities including developing our therapeutic platforms, identifying and developing potential product candidates and undertaking preclinical studies and clinical trials. Additionally, we have supported our research and development activities with general and administrative support, as well as by raising capital, conducting business planning and protecting our intellectual property. We have not generated any revenue from the sale of approved products to date and do not expect to do so until such time as we obtain regulatory approval and commercialize one or more of our product candidates. We cannot be certain of the timing or success of approval of our product candidates.
Since our initial public offering (“IPO”) in 2017, we have funded our operations primarily through follow-on public offerings, including the issuance of pre-funded warrants, and payments received under our license and collaboration agreements. Payments received from our license and collaboration agreements include upfront fees, milestone payments, as well as research support and reimbursement payments. Prior to our IPO, we also received financing from private equity placements and the issuance of convertible debt, which was subsequently converted into equity securities, and a credit facility. From inception to June 30, 2021, we received $796.5 million, net of equity issue costs, from these sources of financing including proceeds from exercises of stock options and employee stock purchase plans. As of June 30, 2021, we had $359.8 million of cash resources consisting of cash, cash equivalents and short-term investments.
Although it is difficult to predict our funding requirements, based upon our current operating plan, we anticipate that our existing cash and cash equivalents and short-term investments as of June 30, 2021, combined with the collaboration payments we anticipate receiving, will enable us to fund our planned operations into the second half of 2022 and potentially beyond.

We reported a net loss of $112.1 million for the six months ended June 30, 2021 and through June 30, 2021, we had an accumulated deficit of $583.4 million. Over the next several years, we expect to continue to incur losses as we increase our research and development expenditures in connection with the ongoing development of our product candidates and other clinical, preclinical and regulatory activities.


Recent Developments

COVID-19

COVID-19 has impacted our research and development activities, but has not caused significant disruptions to our business operations to date. In March 2020, we transitioned our workforce to a remote working arrangement to protect the health and safety of our employees. In June 2020, we implemented a program to facilitate the phased return of employees to our lab and office facilities pursuant to enhanced health and safety protocols consistent with guidelines issued by local health authorities. Our preclinical research activities were supplemented by support from external contract research organizations (“CROs”) to complement the temporarily reduced capacity at our lab facilities. Certain clinical trial activities, including patient enrollment and site activations, were delayed or otherwise impacted by COVID-19. To date, COVID-19 has not had a material impact on our financial condition, liquidity or longer-term strategic development and commercialization plans.

Table of Contents

The extent to which COVID-19 may cause more significant disruptions to our business and greater impacts to our results of operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the duration and severity of outbreaks, including potential future waves or cycles, and the effectiveness of actions to contain and treat COVID-19. A lack of coordinated responses on risk mitigation and vaccination deployment with respect to the COVID-19 pandemic could result in significant increases to the duration and severity of the pandemic and could have a corresponding negative impact on our business. For example, with the increased availability of vaccines in North America and certain countries around the world, the rate of additional COVID-19 infections and hospitalizations has declined in certain locations, resulting in relaxed restrictions and a general reopening of the economy and travel across many jurisdictions. While these developments are promising, reduced vaccine availability or resistance to vaccination by certain persons may result in increasing infection and hospitalization rates, which could be further complicated by the emergence of more virulent or infectious variants of the virus. We cannot predict the duration, scope and severity of any potential business shutdowns or disruptions that may result from future waves or cycles of outbreaks, including impacts to our ongoing and planned clinical studies and our regulatory approval prospects. Further prolonged shutdowns or other business interruptions could result in material and negative effects to our ability to conduct our business in the manner and on the timelines currently planned, which could have a material adverse impact on our business, results of operations, and financial condition. The COVID-19 pandemic continues to rapidly evolve, and we will continue to monitor the effects of COVID-19 on our business. See Part II - Item 1A, “Risk Factors – Risks Related to Our Business and the Development and Commercialization of Our Product Candidates – Our business has been and may continue to be adversely affected by the COVID-19 pandemic.”
Zanidatamab Clinical Program:
In January 2021, we presented updated clinical data at the American Society of Clinical Oncology (“ASCO”) Gastrointestinal Cancers Symposium for zanidatamab, in both HER2-expressing biliary tract cancer (“BTC”) and gastroesophageal adenocarcinoma (“GEA”). Overall, zanidatamab was well tolerated with the majority of treatment-related adverse events being mild or moderate (Grade 1 or 2) in severity, and response rates and median duration of response in refractory BTC and GEA compare favorably to current standard of care and emerging treatments.
In July 2021, we announced the first patient dosed in a new cohort of our Phase 1 trial to evaluate zanidatamab in combination with Seagen’s HER2-selective tyrosine kinase inhibitor, Tukysa (tucatinib), and chemotherapy in patients with previously-treated locally advanced and/or metastatic HER2-expressing breast cancer.
ZW49 Clinical Program:

In January 2021, we announced an interim update from the ongoing ZW49 Phase 1 dose-escalation study. In 35 patients who have received ZW49 across all dosing regimens, there have been no dose-limiting toxicities, no treatment-related hematologic, pulmonary, or liver toxicity, and no treatment-related deaths. Over 90% of treatment-related adverse events have been mild or moderate (Grade 1 or 2) in severity, with the most common being keratitis, fatigue, and diarrhea, which have been reversible and manageable in an outpatient setting. There have been no discontinuations due to treatment-related adverse events, and the maximum tolerated dose has not yet been established. ZW49 has demonstrated antitumor activity at all dose levels evaluated in the once every three week regimen including confirmed partial responses and stable disease per RECIST 1.1. Dose escalation is continuing at 3 mg/kg once every three weeks. Three indication-specific expansion cohorts (HER2-positive breast cancer, HER2-positive GEA, and a basket cohort of other HER2-positive cancers) utilizing the 2.5 mg/kg once every three week regimen have also been initiated to better ascertain antitumor activity in more homogeneous patient populations.
Preclinical Programs:
In April 2021, we presented five posters at the American Association for Cancer Research (AACR) Annual Meeting. The presentations highlight preclinical data that reveal new insights into the unique mechanisms of action of our lead product candidate, zanidatamab, introduce our fourth therapeutic platform, ProTECT, and describe two new preclinical assets focused on the cytokine, IL-12, and the immune-oncology target, 4-1BB.
Licensing and Collaboration Agreements:
In August 2021, we announced that our partner, Janssen, dosed the first patient with a bispecific antibody developed using our Azymetric and EFECT platforms. Under our 2017 collaboration and licensing agreement with Janssen, we will receive a payment in connection with this milestone.

Executive Team Changes:
In January 2021, Mr. James Priour was promoted to Chief Commercial Officer and named to the Executive Committee. In May 2021, Dr. Diana Hausman transitioned from her role as our Chief Medical Officer and Dr. Neil Josephson, our Senior Vice President, Clinical Research, assumed the role of interim Chief Medical Officer. Dr. Hausman will remain with the Company as a clinical advisor through November 2021.
Strategic Partnerships and Collaborations
Our novel product candidates, together with the unique combination of proprietary protein engineering capabilities and resulting therapeutic platform technologies, have enabled us to enter into a number of strategic partnerships, many of which were subsequently expanded in scope. Our strategic partnerships, including with Merck, Lilly, BMS, GSK, Daiichi Sankyo, Janssen, LEO, BeiGene, and Iconic, provide us with the ability to accelerate clinical development of our product candidates in certain geographical regions and provide our strategic partners with access to components of our proprietary therapeutic platforms for their own therapeutics development. In addition, these strategic partnerships have provided us with non-dilutive funding as well as access to proprietary therapeutic assets, which increase our ability to rapidly advance our product candidates while maintaining commercial rights to our own therapeutic pipeline. Under our existing collaboration agreements, we have received $218.0 million to date in the form of non-refundable upfront payments and milestone payments, and we are also eligible to receive up to $2.8 billion in preclinical and development milestone payments and $5.8 billion in commercial milestone payments, as well as tiered royalties on potential future product sales. It is possible, however, that our strategic partners’ programs will not advance as currently contemplated, which would negatively affect the amount of development and commercial milestone payments and royalties on potential future product sales we may receive. Importantly, these partnerships include predominantly non-target-exclusive licenses for any of our therapeutic platforms, so we maintain the ability to develop therapeutics directed to many high-value targets utilizing our platforms.

There have not been any material changes to the key terms of any of our licensing and collaboration agreements, since December 31, 2020. For further information on the terms and conditions of our existing collaboration and license agreements, please refer to “Item 1. Business - Strategic Partnerships and Collaborations” of our Annual Report on Form 10-K for the year ended December 31, 2020.
Financial Operations Overview
Revenue
Our revenue consists of collaboration revenue, including amounts recognized relating to upfront non-refundable payments for licenses or options to obtain future licenses, research and development funding and milestone payments earned under collaboration and license agreements. We expect that collaboration revenue from our strategic partnerships will be our primary source of revenue for the foreseeable future.
Operating Expenses
Our operating expenses consist primarily of research and development expenses and general and administrative expenses. Personnel costs including salaries, benefits, bonuses and stock-based compensation expense, comprise a significant component of research and development and general and administrative expenses. We allocate certain indirect expenses associated with our facilities, information technology, depreciation and other overhead costs between research and development and general and administrative categories based on employee headcount and the nature of work performed by each employee.
Research and Development Expense
Research and development expenses consist of expenses incurred in performing research and development activities such as conducting clinical trials and preclinical research studies, technical and manufacturing operations, regulatory affairs and other indirect expenses in support of advancing our product candidates and therapeutic platforms. Research and development expenses include third-party program costs, internal personnel costs and other indirect costs as follows:
fees paid to CROs, consultants, subcontractors and other third-party vendors for work performed for our clinical trials, preclinical studies and regulatory activities;
fees paid to third-party manufacturers to produce our product candidate supplies;
amounts paid to vendors and suppliers for laboratory supplies;
fees, milestone payments and other expenses incurred in connection with license agreements and amendments;
employee-related expenses such as salaries and benefits and stock-based compensation;
depreciation of laboratory equipment, computers and leasehold improvements; and

overhead expenses such as facilities, information technology and other allocated items.
It is difficult to determine with certainty the duration and completion costs of our current or future clinical trials and preclinical programs of our product candidates, or if, when or to what extent we will generate revenue from the commercialization and sale of any of our product candidates that obtain regulatory approval. We may never succeed in achieving regulatory approval for any of our product candidates. The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including the uncertainties of clinical trials and preclinical studies, uncertainties in clinical trial enrollment rates and significant and changing government regulation. In addition, the probability of success for each product candidate will depend on numerous factors, including competition, manufacturing capability and commercial viability. We will determine which programs to pursue and how much to fund each program in response to the scientific and clinical success of each product candidate, as well as an assessment of each product candidate’s commercial potential. We expect our research and development expenses to increase for the foreseeable future as we continue to develop our platforms and product candidates.
General and Administrative Expense
General and administrative expenses consist of salaries, benefits and stock-based compensation costs for employees in our executive, finance, legal, intellectual property, business development, human resources and other support functions, as well as legal and professional fees, business insurance, facilities and information technology costs and other expenses. We expect general and administrative expenses to increase as we expand our infrastructure to support our ongoing research and development activities.
Other Income (Expense)
Other income (expense) primarily consists of interest income and foreign exchange gain (loss).
Critical Accounting Policies and Significant Judgments and Estimates
Our critical accounting policies are those policies that require the most significant judgments and estimates in the preparation of our interim condensed consolidated financial statements. A summary of our critical accounting policies is presented in note 2 of our annual consolidated financial statements for the year ended December 31, 2020.

Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable. We review and evaluate these estimates on an ongoing basis. These assumptions and estimates form the basis for making judgments about the carrying values of assets and liabilities and amounts that have been recorded as revenue and expenses. Actual results and experiences may differ from these estimates. The results of any material revisions would be reflected in the consolidated financial statements prospectively from the date of the change in estimate.

There have been no material changes in our critical accounting policies and significant judgments and estimates during the three and six months ended June 30, 2021 as compared to what has been described in our most recent annual consolidated financial statements.
