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 intellectual property rights for some of our product candidates are dependent on the abilities of third parties to assert and defend such rights;
patent reform legislation and court decisions can diminish the value of patents in general, thereby impairing our ability to protect our products;
we may not be able to protect our intellectual property rights throughout the world;
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;
additional costs and expenses related to no longer being considered an emerging growth company or a smaller reporting company;
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.

Notes to the Interim Condensed Consolidated Financial Statements
(unaudited)

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, 2019.
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, 2020 and 2019 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, 2019, except for the new accounting guidance adopted during the period (note 3).
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 for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations.

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 the outbreak, 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, 2020, 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
Initial adoption of new accounting pronouncements
In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments—Credit Losses (Topic 326), in order to improve financial reporting of expected credit losses on financial instruments and other commitments to extend credit. ASU 2016-13 requires that an entity measure and recognize expected credit losses for financial assets held at amortized cost and replaces the incurred loss impairment methodology in prior GAAP with a methodology that requires consideration of a broader range of information to estimate credit losses. The Company adopted this accounting standard as of January 1, 2020. The adoption of this standard did not have any impact to the Company's consolidated financial statements as credit losses at the transition date were not expected to be significant, based on the evaluation of the financial condition of payment partners, and external market factors.
In August 2018, the FASB issued ASU 2018–13, Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU eliminate, add and modify certain disclosure requirements for fair value measurements as part of its disclosure framework project. The standard is effective for the Company in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted this accounting standard as of January 1, 2020. The adoption of this new accounting standard did not have a significant impact on the Company’s consolidated financial statements.
In August 2018, the FASB issued ASU 2018–15, Intangibles — Goodwill and Other — Internal Use Software (Subtopic 350–40). This ASU addresses the accounting for implementation costs incurred by a customer in a cloud computing arrangement that is a service contract and also adds certain disclosure requirements related to implementation costs incurred for internal-use software and cloud computing arrangements. The amendment aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted this accounting standard as of January 1, 2020 and has applied it prospectively to all implementation costs incurred after January 1, 2020. The adoption of this new accounting standard did not have a significant impact on the Company’s consolidated financial statements.
Recent accounting pronouncements not yet adopted
The Company has reviewed other recent accounting pronouncements and concluded that they are either not applicable to the business, or that no material impact is expected on the consolidated financial statements as a result of future adoption.

5. Investments
Short-term Investments
Short-term investments consist of guaranteed investment certificates (“GICs”), term deposits and commercial paper acquired from financial institutions in accordance with the Company’s treasury policy. Short-term GICs, term deposits and commercial paper bear interest at rates of 0.8%-2.0% per annum with original maturities of up to 12 months, are classified as held to maturity and are accounted for at amortized cost.
Long-term Investments
Long-term investments at June 30, 2020 consist of GIC's and term deposits of $75,260 (December 31, 2019 -$nil) acquired from financial institutions in accordance with the Company’s treasury policy and other debt and equity securities of $718 (December 31, 2019 - $nil) acquired for strategic purposes or in connection with licensing and collaboration agreements. Long-term GICs and term deposits bear interest at rates of 0.9%-1.0% per annum with original maturities ranging from 12 to 24 months, are classified as held to maturity and are accounted for at amortized cost. Other long-term debt and equity securities are accounted for as available for sale financial instruments with changes in fair value recorded through other comprehensive income or at cost subject to impairment.
6. IPR&D and Goodwill
Acquired IPR&D
In-process research and development assets (“IPR&D”) acquired in the 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, 2020 and December 31, 2019. The Company concluded that there were no impairment indicators related to IPR&D as of June 30, 2020.
Goodwill
The Company performed its most recent annual impairment test of goodwill as of December 31, 2019. 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, 2019, 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, 2020.

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 ten-year life. Common shares are issued from treasury when options are exercised.
Options issued to employees under the Original Plan vest over 4 years. Options issued to directors under the Original Plan vest over 3 years, 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 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 maximum number of common shares reserved for issuance under the New Plan is 8,654,682, which includes 6,294,820 shares issuable upon exercise of options outstanding as of June 30, 2020. Beginning in 2020 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, 2020 , the Company granted 78,679 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. The grant date fair value for the RSUs granted in the six months ended June 30, 2020 was $2,786.
Stock Options
All options granted under the New Plan will have an exercise price determined and approved by the Board 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 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 at the fair market value of the Company’s stock at the date the grant is approved by the Board. 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, with input from management. Management estimated the fair value
