FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q contains forward-looking statements. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, our clinical results and other future conditions. The words “aim,” “anticipate,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “goal,” “intend,” “may,” “on track,” “plan,” “possible,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” “would” or the negative of these terms or other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.
These forward-looking statements include, among other things, statements about:
the initiation, cost, timing, progress and results of our current and future research and development activities and preclinical and clinical studies;
the adequacy of our inventory of XMT-1536 and XMT-1592 to support our ongoing clinical studies, as well as the outcome of planned manufacturing runs;
the timing of, and our ability to obtain and maintain, regulatory approvals for our product candidates;
unmet need of ovarian cancer and non-small cell lung cancer;
our ability to quickly and efficiently identify and develop additional product candidates;
our ability to advance any product candidate into, and successfully complete, clinical studies;
our intellectual property position, including with respect to our trade secrets;
the potential benefits of strategic partnership agreements and our ability to enter into selective strategic partnerships;
our estimates regarding expenses, future revenues, capital requirements, the sufficiency of our current and expected cash resources and our need for additional financing; and
the potential impact of the ongoing COVID-19 pandemic.
We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. We have included important factors in the cautionary statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 and our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2020, particularly in the “Risk Factors” sections, that we believe could cause actual results or events to differ materially from the forward-looking statements that we make. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments we may make.
In addition, while we expect that the COVID-19 pandemic might adversely affect our preclinical and clinical development efforts, business operations and financial results, the extent of the impact and the value of and market for our common stock will depend on future developments that are highly uncertain and cannot be predicted with confidence at this time, such as the ultimate duration of the pandemic, travel restrictions, quarantines, physical distancing and business closure requirements in the U.S. and in other countries, and the effectiveness of actions taken globally to contain and treat the disease.
The forward-looking statements contained herein represent our views as of the date of this Quarterly Report on Form 10-Q. We anticipate that subsequent events and developments will cause our views to change. You should, therefore, not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this Quarterly Report on Form 10-Q.

1. Nature of business and basis of presentation
Mersana Therapeutics, Inc. is a clinical stage biopharmaceutical company focused on developing antibody drug conjugates (ADCs) that offer a clinically meaningful benefit for cancer patients with significant unmet need. The Company has leveraged 20 years of industry learning in the ADC field to develop proprietary and differentiated technology platforms that enable it to design ADCs to have improved efficacy, safety and tolerability relative to existing ADC therapies. The Company’s innovative platforms, which include Dolaflexin and Dolasynthen, each delivering its DolaLock payload, as well as Immunosynthen, delivering a novel stimulator of interferon genes (STING) agonist, provide an efficient product engine that has enabled a robust discovery pipeline for the Company and its partners. The Company’s product candidates include XMT-1536 and XMT-1592. The Company's early stage programs include a potentially first-in-class B7-H4-targeted DolaLock ADC as well as candidates leveraging the Immunosynthen platform.
XMT-1536, an ADC utilizing the Company’s Dolaflexin platform and targeting NaPi2b, an antigen broadly expressed in ovarian cancer and non-small cell lung cancer (NSCLC) adenocarcinoma, is currently in the expansion portion of a Phase 1 study in patients with ovarian cancer and NSCLC adenocarcinoma. XMT-1592 uses one of the Company’s new platforms, Dolasynthen, and also targets NaPi2b. The Company filed an Investigational New Drug (IND) application in the first quarter of 2020 and initiated the Phase 1 dose escalation study of XMT-1592 in the second quarter of 2020.
The Company has incurred cumulative net losses since inception. For the six months ended June 30, 2020, the net loss was $36,712, compared to net income of $4,830 in the six months ended June 30, 2019. The difference year over year is primarily attributable to $39,965 in deferred revenue that was recognized in the first quarter of 2019 as a result of the discontinuation of the partnership with Takeda in the first quarter of 2019. The Company expects to continue to incur operating losses for at least the next several years. As of June 30, 2020, the Company had an accumulated deficit of $229,086. The future success of the Company is dependent on, among other factors, its ability to identify and develop its product candidates and ultimately upon its ability to attain profitable operations. The Company has devoted substantially all of its financial resources and efforts to research and development and general and administrative expense to support such research and development. Net losses and negative operating cash flows have had, and will continue to have, an adverse effect on the Company’s stockholders' equity and working capital.
In April 2020, the Company sold 10,900,599 shares of common stock and received net proceeds of $62,976. In addition, in June 2020, the Company sold 9,200,000 shares of common stock and received net proceeds of $163,991. The Company believes that its currently available funds will be sufficient to fund the Company’s operations through at least the next twelve months from the issuance of this Quarterly Report on Form 10-Q. Management’s belief with respect to its ability to fund operations is based on estimates that are subject to risks and uncertainties. If actual results are different from management’s estimates, the Company may need to seek additional funding.
The Company is subject to risks common to companies in the biotechnology industry, including but not limited to, the need for additional capital, risks of failure of preclinical and clinical studies, the need to obtain marketing approval and reimbursement for any drug product candidate that it may identify and develop, the need to successfully commercialize and gain market acceptance of its product candidates, dependence on key personnel, protection of proprietary technology, compliance with government regulations, development of technological innovations by competitors, reliance on third party manufacturers and the ability to transition from pilot-scale production to large-scale manufacturing of products.
The Company’s unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) and the rules and regulations of the Securities and Exchange Commission (SEC). Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards

2. Summary of Significant Accounting Policies
Principles of Consolidation
The accompanying unaudited condensed consolidated financial statements include those of the Company and its wholly-owned subsidiary, Mersana Securities Corp. All intercompany balances and transactions have been eliminated.
Use of Estimates
The preparation of the Company’s unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenue, expenses and related disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. On an ongoing basis, the Company’s management evaluates its estimates which include, but are not limited to, management’s judgments with respect to the identification of performance obligations and standalone selling prices of those performance obligations within its revenue arrangements, accrued expenses, valuation of stock-based awards and income taxes. Actual results could differ from those estimates.
Segment Information
Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision-maker, or decision making group, in deciding how to allocate resources and assess performance. The Company views its operations and manages its business as a single operating segment, which is the business of discovering and developing ADCs.
Summary of Accounting Policies
The significant accounting policies used in preparation of these condensed consolidated financial statements for the three and six months ended June 30, 2020 are consistent with those discussed in Note 2 to the consolidated financial statements in the Company’s 2019 Annual Report on Form 10-K.

Fair Value Measurements
Fair value is defined as the price that would be received upon sale of an asset or paid to transfer a liability between market participants at measurement dates. ASC Topic 820 Fair Value Measurement (ASC 820) establishes a three-level valuation hierarchy for instruments measured at fair value. The hierarchy is based on the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:
Level 1—Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2—Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
Level 3—Inputs to the valuation methodology are unobservable and significant to the fair value measurement.
Cash and Cash Equivalents
The Company considers all highly-liquid investments with an original maturity, or a remaining maturity at the time of purchase, of three months or less to be cash equivalents. The Company invests excess cash primarily in money market funds, commercial paper and government agency securities, which are highly liquid and have strong credit ratings. These investments are subject to minimal credit and market risks. Cash and cash equivalents are stated at cost, which approximates market value.

Marketable Securities
Short-term marketable securities consist of investments in debt securities with maturities greater than three months and less than one year from the balance sheet date. The Company classifies all of its marketable securities as available-for-sale. Accordingly, these investments are recorded at fair value. Amortization and accretion of discounts and premiums are recorded as interest income within other income. Unrealized gains and losses on available-for-sale securities are included in other accumulated comprehensive income (loss) as a component of stockholders’ equity until realized. Realized gains and losses and declines in value judged to be other than temporary are included as a component of other income (expense), net, based on the specific identification method. When determining whether a decline in value is other than temporary, the Company considers various factors, including whether the Company has the intent to sell the security, and whether it is more likely than not that the Company will be required to sell the security prior to recovery of its amortized cost basis. Fair value is determined based on quoted market prices.
Other Assets
The Company recorded other assets of $2,103 and $1,453 as of June 30, 2020 and December 31, 2019, respectively, comprised of $1,782 and $1,132, respectively, held by a service provider, and restricted cash of $321 at the end of each period held as security deposits for a standby letter of credit related to a facility lease.

Net Loss per Share
Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, without further consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock and potentially dilutive securities outstanding for the period determined using the treasury stock and if-converted methods.
For purposes of the diluted net loss per share calculation, stock options, unvested restricted stock units (RSUs), warrants to purchase common stock and options to purchase common stock are considered to be potentially dilutive securities, but are excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive. Therefore, basic and diluted net loss per share were the same for the three months ended June 30, 2020 and 2019 and the six months ended June 30, 2020.
The following table sets forth the outstanding potentially dilutive securities that have been excluded from the calculation of diluted net loss per share for the three and six months ended June 30, 2020 and the three months ended June 30, 2019, because to include them would be anti-dilutive (in common stock equivalent shares):

For the six months ended June 30, 2019, the Company reported net income. Diluted earnings per share was computed using the "treasury method" by dividing the net income by the weighted-average number of shares of common stock and potentially dilutive securities outstanding during the period. The weighted-average number of shares of common stock were adjusted for the potential dilutive effect of the exercise of stock options and warrants to purchase common stock. Refer to Note 7, "Earnings per share."
Recently Issued Accounting Pronouncements
In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808):Clarifying the Interaction between Topic 808 and Topic 606. The main provisions of ASU 2018-18 include: (i) clarifying that certain transactions between collaborative arrangement participants should be accounted for as revenue when the collaborative arrangement participant is a customer in the context of a unit of account and (ii) precluding the presentation of transactions with collaborative arrangement participants that are not directly related to sales to third parties together with revenue. This guidance is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those annual reporting periods, and early adoption is permitted. The guidance per ASU 2018-18 is to be adopted retrospectively to the date of initial application of Topic 606. The Company adopted the new standard effective January 1, 2020. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements and related disclosures.
In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires that financial assets measured at amortized cost be presented at the net amount expected to be collected. Currently, U.S. GAAP delays recognition of the full amount of credit losses until the loss is probable of occurring. Under this ASU, the income statement will reflect an entity’s current estimate of all expected credit losses. The measurement of expected credit losses will be based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit

losses rather than as a direct write-down of the security. This ASU is effective for annual periods beginning after December 15, 2019, including interim periods within those annual reporting periods, and early adoption is permitted. The Company adopted the new standard effective January 1, 2020 using the modified retrospective method. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements and related disclosures.
3. Collaboration agreements
Merck KGaA
In June 2014, the Company entered into a Collaboration and Commercial License Agreement with Merck KGaA (the Merck KGaA Agreement). Upon the execution of the agreement, Merck KGaA paid the Company a nonrefundable technology access fee of $12,000 for the right to develop ADCs directed to six exclusive targets over a specified period of time. No additional fees are due when a target is designated and the commercial license to the target is granted. Merck KGaA will be responsible for the product development and marketing of any products resulting from this collaboration. All six targets were designated prior to 2018. The Company is eligible to receive milestones under the Merck KGaA Agreement. The next potential milestone payment is a development milestone of $500 on Merck KGaA’s designation of a preclinical development candidate for a target. Revenue for the milestone is fully constrained until it is certain the milestone would be achieved.
Under the terms of the Merck KGaA Agreement, the Company and Merck KGaA develop research plans to evaluate Merck KGaA's antibodies as ADCs incorporating the Company's technology. The Company receives reimbursement for its efforts under the research plans. The goal of the research plans is to provide Merck KGaA with sufficient information to formally nominate a development candidate and begin IND-enabling studies or cease development on the designated target.
In May 2018, the Company entered into a Supply Agreement with Merck KGaA (the Merck KGaA Supply Agreement). Under the terms of the Merck KGaA Supply Agreement, the Company will provide Merck KGaA preclinical non-GMP ADC Drug Substance and clinical GMP Drug Substance for use in clinical trials associated with one of the antibodies designated under the Merck KGaA Agreement. The Company receives fees for its efforts under the Merck KGaA Supply Agreement and reimbursement equal to the supply cost. The Company may also enter into future supply agreements to provide clinical supply material should Merck KGaA pursue clinical development of any other candidates nominated under the Merck KGaA Agreement.
Accounting Analysis
The Company identified the following performance obligations under the Merck KGaA agreement: (i) exclusive license and research services for six designated targets, (ii) rights to future technological improvements and (iii) participation of project team leaders and providing joint research committee services.
The Company is recognizing revenue related to the exclusive license and research and development services over the estimated period of the research and development services using a proportional performance model. The Company measures proportional performance based on the costs incurred relative to the total costs expected to be incurred. To the extent that the Company receives fees for the research services as they are performed, these amounts are recorded as deferred revenue. Revenue related to future technological improvements and joint research committee services will be recognized ratably over the respective performance period (which in the case of the joint research committee services approximates the time and cost incurred each period), which are 10 and five years, respectively. The Company is continuing to reassess the estimated remaining term at each subsequent reporting period. As of December 31, 2019, the total transaction price for the Merck KGaA Agreement was $21,500, which represented the amount of consideration the Company was expected to receive for the transfer of goods and services to Merck KGaA. For each of the three and six months ended June 30, 2020, the Company decreased the fees expected to be received for research and development activities by $175 to $6,325, resulting in a revised total transaction price for the Merck KGaA Agreement of $21,325 as of June 30, 2020.

During the three months ended June 30, 2020, the Company completed its performance obligations associated with one of the six designated targets. For the three months ended June 30, 2020 and 2019, and the six months ended June 30, 2020 and 2019, the Company recorded collaboration revenue of $796, $18, $807, and $36, respectively, related to its efforts under the Merck KGaA Agreement. During the three and six months ended June 30, 2019, the Company recognized $184 and $1,221, respectively, in collaboration revenue and corresponding research and development expense of $184 and $1,221, respectively, related to the Merck KGaA Supply Agreement.
As of June 30, 2020 and December 31, 2019, the Company had $4,008 and $4,815, respectively, in deferred revenue related to the Merck KGaA Agreement and Merck KGaA Supply Agreement that will be recognized over the remaining performance period.
Takeda XMT-1522 Strategic Partnership
In January 2016, the Company entered into a Development Collaboration and Commercial License Agreement with Takeda's wholly owned subsidiary, Millennium Pharmaceuticals, Inc. for the development and commercialization of XMT-1522 (the XMT-1522 Agreement). Under the XMT-1522 Agreement, Takeda was granted the exclusive right to commercialize XMT-1522 outside of the United States and Canada. Under the XMT-1522 Agreement, the Company was responsible for conducting certain Phase 1 development activities for XMT-1522, including the ongoing Phase 1 clinical trial, at its own expense. The parties agreed to collaborate on the further development of XMT-1522 in accordance with a global development plan (Post-Phase 1 Development). On January 2, 2019, the Company received notice from Takeda stating that Takeda was exercising its right to terminate the XMT-1522 Agreement upon 30 days’ prior written notice. The XMT-1522 Agreement terminated in accordance with its provisions, and the Company and Takeda wound down activities related to the XMT-1522 Agreement as of March 31, 2019. Under the XMT-1522 Agreement, the Company and Takeda shared equally all Post-Phase 1 Development costs through the date of termination and for a period of 30 days after the effective termination date.
For the applicable period within the three months ended March 31, 2019, the Company was billed $200 by Takeda, representing the Company’s share of Post-Phase 1 Development costs incurred by Takeda. This amount has been reflected as research and development costs in the consolidated statement of operations.
Takeda strategic research and development partnership
In March 2014, the Company entered into a Research Collaboration and Commercial License Agreement with Takeda through Takeda’s wholly owned subsidiary, Millennium Pharmaceuticals, Inc. (the 2014 Agreement). The 2014 Agreement was amended in January 2015 and amended and restated in January 2016 (the 2016 Restated Agreement). The agreements provided Takeda with the right to develop ADCs directed to a total of seven exclusive targets, designated by Takeda, over a specified period of time. On January 2, 2019, the Company received notice from Takeda stating that Takeda was exercising its right to terminate the 2016 Restated Agreement upon 45 days’ prior written notice. The 2016 Restated Agreement terminated in accordance with its provisions, and the Company and Takeda wound down activities related to the 2016 Restated Agreement as of March 31, 2019.
During the applicable period within the three months ended March 31, 2019, the Company billed Takeda $195 related to ASC 808 costs.
Accounting Analysis
The Company’s collaboration agreements with Takeda were terminated following receipt of written notices during the first quarter of 2019. As there are no further performance obligations, the Company recognized the remaining deferred revenue of $39,965 related to the termination of the Takeda agreements in the first quarter of 2019.
Included in accounts payable as of June 30, 2020 and December 31, 2019 was $2,335 related to the Takeda agreements.

Other Revenue
The Company has provided limited services for a collaboration partner, Asana BioSciences. For the six months ended June 30, 2019, the Company recognized $15 of revenue related to these services. The Company did not recognize any revenue related to these services for the three months ended June 30, 2020 and 2019 and the six months ended June 30, 2020. The next potential milestone the Company is eligible to receive is $2,500 upon dosing the fifth patient in a Phase 1 clinical study by Asana BioSciences. As of June 30, 2020, the Company considers this next milestone to be fully constrained as there is considerable judgment involved in determining whether it is probable that a significant revenue reversal would occur. As part of its evaluation of the constraint, the Company considered numerous factors, including the fact that achievement of the milestone is outside the control of the Company and there is a high level of uncertainty in achieving this milestone, as this would require successful initiation of clinical trials by the collaboration partner. The Company reevaluates the probability of achievement of a milestone subject to constraint at each reporting period and as uncertain events are resolved or other changes in circumstances occur.

therefore basic and diluted net loss per share were the same for the three months ended June 30, 2020 and 2019 and the six months ended June 30, 2020.
8. Debt
On May 8, 2019, the Company entered into a loan and security agreement (the Credit Facility) with Silicon Valley Bank (SVB) pursuant to which the Company can borrow, at its option, up to $20,000, in up to four principal advances of at least $5,000 each (each, a Term Loan or collectively, the Term Loans) through August 31, 2020. The Company drew $5,000 on the Term Loan upon execution of the Credit Facility.
In the event the Company has not borrowed a total of $20,000 upon the earlier of August 31, 2020, acceleration of the Company’s payment obligations or Company’s prepayment of the then extended Term Loans, the Company is required to pay an additional fee equal to 3.0% of any unborrowed portion of the committed funding (the Unused Term Loan Commitment Fee).
As of June 30, 2020, the Company was in compliance with all covenants under the Credit Facility. As such, as of June 30, 2020, the classification of the loan balance as stated on the balance sheet was based on the timing of defined future payment obligations.
As of June 30, 2020, the Company had drawn a Term Loan of $5,000.

10. Stock options
Stock option plans
In June 2017 the Company’s shareholders approved the 2017 Stock Incentive Plan (the 2017 Plan). Under the 2017 Plan, up to 2,255,000 shares of common stock were initially available to be granted to the Company's employees, officers, directors, consultants and advisors in the form of options, restricted stock units (RSUs) or other stock-based awards. The number of shares of common stock issuable under the 2017 Plan will be cumulatively increased annually by 4% of the outstanding shares or such lesser amount specified by the Board. The terms of the awards are determined by the Board, subject to the provisions of the 2017 Plan. Any cancellations under the 2007 Plan, which expired in June 2017, would increase the number of shares that could be granted under the 2017 Plan. In January 2020, the number of shares of common stock issuable under the 2017 Plan was increased by 1,815,520 shares. As of June 30, 2020, there were 1,557,386 shares available for future issuance under the 2017 Plan.
With respect to incentive stock options, the exercise price per share will equal the fair market value of the common stock on the date of grant, and the vesting period is generally four years. Nonqualified stock options will be granted at an exercise price established by the Board at its sole discretion (which has not been less than fair market value on the date of grant) and the vesting periods may vary. Options granted under the 2017 Plan expire no later than 10 years from the date of grant. The Board may accelerate vesting or extend the expiration of granted options in the case of a merger, consolidation, dissolution, or liquidation of the Company.

Stock-based compensation expense
The Company uses the provisions of ASC 718, Stock Compensation, to account for all stock-based awards to employees and non-employees.
The measurement date for employee awards is generally the date of grant. Stock-based compensation expense is recognized over the requisite service period, which is generally the vesting period, using the straight-line method.

Employee Stock Purchase Plan
During the year ended December 31, 2017, the Board adopted, and the Company’s stockholders approved the 2017 employee stock purchase plan (the 2017 ESPP). The Company initially reserved 225,000 shares of common stock for issuance under the 2017 ESPP. In January 2020, the number of shares of common stock for issuance under the 2017 ESPP was increased by 450,000 shares. For the three months ended June 30, 2020 and 2019 and the six months ended June 30, 2020 and 2019, the Company issued 68,419, 82,281, 68,419, and 82,281, respectively, shares under the 2017 ESPP. As of June 30, 2020, there were 656,666 shares available for issuance under the 2017 ESPP.
11. Leases
The Company has an operating lease for its office space in Cambridge, MA and operating and finance leases for certain equipment. In March 2020, the Company entered into the Seventh Amendment to the office space lease to extend the term of the lease through March 2026 and to provide the Company with a tenant improvement allowance of $172. The current rate per square foot that is in place through March 2021 (the original expiration date of the lease) did not change. After March 2021, there are predetermined fixed escalations of the rate as outlined in the amendment. The Company has an option to extend the lease term for an additional five years. The Company’s exercise of this option was not considered reasonably certain as of June 30, 2020.
The extension is accounted for as a lease modification. The Company assessed the lease classification of the amended office space lease at the modification date and determined that the amended office space lease should be accounted for as an operating lease. The right-of-use asset and corresponding operating lease liability have been remeasured based on the present value of remaining lease payments over the remaining extended lease term, using the incremental borrowing rate applicable as of the lease modification date. The Company determined the appropriate incremental borrowing rate by using a synthetic credit rating which was estimated based on an analysis of outstanding debt of companies with similar credit and financial profiles. Since the operating lease is a net lease, as

(unaudited)
the non-lease components (i.e., common area maintenance) are paid separately from rent based on actual costs incurred, such non-lease components were not included in the right-of-use asset and liability and are reflected as an expense in the period incurred.
As a result of the modification in March 2020, the Company recorded an increase of $9,980 to its right-of-use (ROU) asset and lease liabilities in the first quarter of 2020.
Following the change, the Company's future minimum lease payments under non-cancellable leases as of June 30, 2020 were as follows:

12. Commitments
License agreements
Through June 30, 2020, the Company had licensed intellectual property from three biotechnology companies. The consideration included upfront payments and a commitment to pay annual license fees, milestone payments and, upon product commercialization, royalties on revenue generated from the sale of products covered by the licenses. The Company recorded a $750 milestone payment for the dosing of the first patient in the XMT-1592 trial during each of the three and six months ended June 30, 2020. The Company did not record any milestone payments during either of the three and six months ended June 30, 2019.

Overview
We are a clinical-stage biopharmaceutical company focused on developing antibody drug conjugates, or ADCs, that offer a clinically meaningful benefit for cancer patients with significant unmet need. We have leveraged 20 years of industry learning in the ADC field to develop proprietary and differentiated technology platforms that enable us to design ADCs to have improved efficacy, safety and tolerability relative to existing ADC therapies.
We believe that our innovative platforms which include Dolaflexin and Dolasynthen, each delivering our DolaLock payload, as well as Immunosynthen, delivering a novel stimulator of interferon genes, or STING, agonist, provide a highly-efficient product engine that has enabled a robust discovery pipeline for us and our partners. Our ADCs in preclinical and clinical studies are first-in-class molecules that target multiple tumor types with high unmet medical need and have exhibited improved safety and efficacy compared to ADCs developed using first-generation technology.
Our goal is to become a leading oncology company by leveraging the potential of our innovative and differentiated ADC technologies and the experience and competencies of our management team to identify, acquire and develop promising ADC product candidates and to commercialize cancer therapeutics that are improvements over existing treatments.
XMT-1536, a first-in-class ADC targeting the sodium-dependent phosphate transport protein NaPi2b, utilizes the Dolaflexin platform to deliver an average of 10 to 12 DolaLock payload molecules per antibody. The NaPi2b antigen is broadly expressed in NSCLC adenocarcinoma and ovarian cancer with limited expression in normal tissue. We are actively recruiting and dosing patients with ovarian cancer and NSCLC adenocarcinoma, where a majority of patients express NaPi2b, in a Phase 1 clinical trial.
23

Table of Contents
We have also selected our next clinical product candidate, XMT-1592. XMT-1592 uses one of our new platforms, Dolasynthen, and also targets NaPi2b. XMT-1592 comprises the same proprietary NaPi2b antibody and potent auristatin DolaLock payload with controlled bystander effect as XMT-1536, with the additional features of homogeneous, site-specific bioconjugation and precise drug-to-antibody ratio, or DAR. We filed an Investigational New Drug (IND) application in the first quarter of 2020 and initiated the Phase 1 dose escalation study of XMT-1592 in the second quarter of 2020.
Our early-stage programs include a potentially first-in-class B7-H4-targeted DolaLock ADC. Our objective is to rapidly progress through IND-enabling studies and scale up manufacturing activities with third parties. B7-H4 provides significant opportunities for development in areas of high unmet need such as breast cancer, NSCLC and ovarian cancer.
In addition, we have established strategic research and development partnerships with Merck KGaA and Asana Biosciences for the development and commercialization of additional ADC product candidates against a limited number of targets selected by our partners based on our Fleximer platform. We believe the potential of our ADC technologies, supported by our world-class management team and protected by our robust intellectual property portfolio, will allow us to develop targeted and highly tailored therapies to help cancer patients become cancer survivors.
Since inception, our operations have focused on such matters as building our platforms, identifying potential product candidates, producing drug substance and drug product material for use in preclinical studies, conducting preclinical and toxicology studies, manufacturing clinical study material and conducting clinical studies, establishing and protecting our intellectual property, staffing our company and raising capital. We do not have any products approved for sale and have not generated any revenue from product sales. We have funded our operations primarily through our strategic partnerships, private placements of our convertible preferred stock and public offerings of our common stock. In April 2020, we sold approximately 10.9 million shares of common stock and received net proceeds of $63.0 million. In addition, in June 2020, we sold 9.2 million shares of common stock and received net proceeds of $164.0 million.
Since inception, we have incurred significant cumulative operating losses. For the six months ended June 30, 2020, the net loss was $36.7 million, compared to net income of $4.8 million in the six months ended June 30, 2019. The difference year over year is primarily attributable to $40.0 million in revenue that was recognized in the first quarter of 2019 as a result of the discontinuation of the partnership with Takeda in that quarter. As of June 30, 2020, we had an accumulated deficit of $229.1 million. We expect to continue to incur significant expenses and operating losses over the next several years. We anticipate that our expenses will increase significantly in connection with our ongoing activities, as we:
continue clinical development activities for our lead product candidates XMT-1536 and XMT-1592;
develop a research assay and companion diagnostic for the NaPi2b biomarker;
continue activities to discover, validate and develop additional product candidates;
maintain, expand and protect our intellectual property portfolio; and
hire additional research, development and general and administrative personnel.
Impact of COVID-19 on Our Business
The coronavirus pandemic continues to evolve rapidly. We are monitoring the impact of the COVID-19 pandemic on operations and ongoing clinical and preclinical development, as well as discovery efforts. Mitigation activities to minimize COVID-19-related operation disruptions are ongoing and include:

Table of Contents
In line with guidance from the U.S. Centers for Disease Control and Prevention (CDC) and the Commonwealth of Massachusetts, we have implemented work from home measures for all non-laboratory employees and have suspended all business travel. We have also prioritized laboratory activities and implemented staggered schedules in the interest of safety and efficiency for laboratory-based employees. We will continue to modify and adapt our measures to align with guidance as the pandemic evolves.
We are currently enrolling patients at investigational sites in different geographic areas across the United States in the XMT-1536 Phase 1 study and the XMT-1592 Phase 1 dose escalation study. We are in the process of initiating additional clinical sites both inside and outside the United States to increase enrollment, which could additionally mitigate potential impacts from COVID-19. Consistent with FDA guidance, we issued an administrative letter to allow for remote patient monitoring and remote testing, when possible.
To the best of our knowledge, our contract manufacturing partners continue to operate their manufacturing facilities at or near normal levels, and we have not experienced any COVID-related delays in our manufacturing to date. We believe we have sufficient inventory of XMT-1536 and XMT-1592 to support our ongoing clinical studies. We have planned manufacturing runs to address all currently anticipated future needs. At this time, and subject to further COVID-19 implications, we do not anticipate any disruptions to our clinical supply.
The ultimate impact of the coronavirus pandemic on our business operations is highly uncertain and subject to change and will depend on future developments, which cannot be accurately predicted. While the pandemic did not materially affect our financial results and business operations in the second quarter ended June 30, 2020, we are unable to predict the impact that COVID-19 will have on our financial position and operating results in future periods due to numerous uncertainties. Management is actively monitoring this situation and the possible effects on our financial condition, operations, suppliers, industry, and our employees. For additional information about risks and uncertainties related to the COVID-19 pandemic that may impact our business, our financial condition or our results of operations, see “Part II, Item 1A—Risk Factors” below in this Form 10-Q.
Financial operations overview
Revenue
To date, we have not generated any revenue from the sale of products. All of our revenue has been generated from strategic partnerships.
In June 2014, we entered into an agreement with Merck KGaA for the development and commercialization of ADC product candidates utilizing Fleximer for up to six target antigens. Merck KGaA is responsible for generating antibodies against the target antigens and we are responsible for generating Fleximer and our proprietary payloads and conjugating this to the antibody to create the ADC product candidates. Merck KGaA has the exclusive right to and is responsible for the further development and commercialization of these ADC product candidates. In May 2018, we entered into a supply agreement with Merck KGaA for the supply of materials that could be used for IND-enabling studies and clinical trials.
For the three months ended June 30, 2020 and 2019 and the six months ended June 30, 2020 and 2019, we recognized revenue of $0.8 million, $0.2 million, $0.8 million, and $1.2 million, respectively, related to the Merck KGaA agreements.
In January 2016, we entered into collaboration agreements with Takeda for the development and commercialization of XMT-1522, a HER2-targeted ADC, and up to seven ADC product candidates utilizing Fleximer. Our collaboration agreements with Takeda were terminated during the first quarter of 2019. We recognized the remaining deferred revenue of $40.0 million related to the termination of the Takeda agreements in the first quarter of 2019. We do not expect to have any further revenue related to these agreements.
25

Table of Contents
We have provided limited services to Asana BioSciences. For the six months ended June 30, 2019 we recorded an immaterial amount of revenue related to these services. We did not record any revenue related to these services in the three and six months ended June 30, 2020 and the three months ended June 30, 2019.
For the foreseeable future, we expect substantially all of our revenue to be generated from our collaboration agreements with Merck KGaA and Asana BioSciences. Given the uncertain nature and timing of clinical development, we cannot predict when or whether we will receive further milestone payments or any royalty payments under these collaborations.
Operating expenses
Research and development expenses
Research and development expenses consist primarily of costs incurred for our research and development activities, including our drug discovery efforts, and the development of our product candidates, which include:
employee-related expenses, including salaries, bonuses, benefits and stock-based compensation expense;
costs of funding research and development performed by third parties that conduct research, preclinical activities, manufacturing and clinical trials on our behalf;
laboratory supplies;
facility costs, including rent, depreciation and maintenance expenses; and
upfront and milestone payments under our third-party licensing agreements.
Research and development costs are expensed as incurred. Costs of certain activities, such as manufacturing and preclinical and clinical studies, are generally recognized based on an evaluation of the progress to completion of specific tasks. Costs for certain development activities, such as clinical studies, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations and information provided to us by the third parties with whom we contract.
Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials and manufacturing costs. We expect that our total future research and development costs will continue to increase over current levels, depending on the progress of our clinical development programs. There are numerous factors associated with the successful development and commercialization of any of our product candidates, including future trial design and various regulatory requirements, many of which cannot be determined with accuracy at our current stage of development. Additionally, future commercial and regulatory factors beyond our control may impact our clinical development programs and plans.
A significant portion of our research and development costs have been external costs, which we track on a program-by-program basis following nomination as a product candidate. We have not historically tracked all of our internal research and development expenses on a program-by-program basis as they are deployed across multiple projects under development. The following table summarizes our external research and development expenses, by program, following nomination as a development candidate for the three and six months ended June 30, 2020 and 2019. All external research and development expenses not attributable to the XMT-1536, XMT-1592 and XMT-1522 programs are captured within preclinical and discovery costs. These costs relate to XMT-1592 prior to its designation in early 2020 as our next ADC clinical candidate, as well as additional earlier discovery stage programs and certain unallocated costs. We terminated the development of XMT-1522 in the first quarter of 2019. Our internal research and development costs are primarily personnel-related costs, stock-based compensation costs, and facility costs, including depreciation, and lab consumables.

Total research and development costs$15,413  $13,766  $27,632  $28,909  
The successful development of our product candidates is highly uncertain. As such, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the remainder of the development of our product candidates. We are also unable to predict when, if ever, material net cash inflows will commence from the development efforts associated with our product candidates. This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of:
successful completion of preclinical studies and IND-enabling studies;
successful enrollment in and completion of clinical trials;
receipt of marketing approvals from applicable regulatory authorities;
establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;
obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our product candidates;
commercializing the product candidates, if and when approved, whether alone or in collaboration with others; and
continued acceptable safety profile of the drugs following approval.
A change in the outcome of any of these or other variables with respect to the development, manufacture or commercialization of any of our product candidates would significantly change the costs, timing and viability associated with the development of that product candidate.
General and administrative expenses
General and administrative expenses consist primarily of salaries and other employee-related costs, including stock-based compensation, for personnel in executive, finance, accounting, business development, legal operations, information technology and human resources functions. Other significant costs include facility costs not otherwise included in research and development expenses, legal and other fees relating to patent and corporate matters, and fees for accounting and consulting services.
We anticipate that our general and administrative expenses will increase in the future to support continued research and development activities, including increased costs related to the hiring of additional personnel, fees to outside consultants and patent costs, among other expenses.

Table of Contents
Other income (expense)
Other income (expense) consists primarily of interest income earned on cash equivalents and marketable securities. Interest expense is related to borrowings under the credit facility that we entered into on May 9, 2019. These borrowings bear a floating per annum rate interest, as well as a final payment of 5% of the amounts drawn, that is being recorded as interest expense over the term through the maturity date using the effective-interest method. Also included in interest expense is the amortization of the deferred financing costs and the accretion of debt discount relating to the credit facility.

Collaboration Revenue
Collaboration revenue was $0.8 million during the three months ended June 30, 2020 and $0.2 million during the three months ended June 30, 2019. The increase in collaboration revenue was primarily a result of the completion of research services associated with a target included in the Merck KGaA Agreement, which resulted in the recognition of $0.8 million of revenue. Additionally, during the three months ended June 30, 2019, collaboration revenue of $0.2 million was recognized related to the Merck KGaA Agreement and Merck KGaA Supply Agreement.
Research and Development Expense
Research and development expense increased by $1.6 million from $13.8 million for the three months ended June 30, 2019 to $15.4 million for the three months ended June 30, 2020.
The increase in research and development expense was primarily attributable to the following:
an increase of $1.1 million related to XMT-1536 clinical and regulatory expenses;
an increase of $0.8 million related to XMT-1592 clinical and regulatory expenses;
an increase of $0.8 million related to a milestone paid for dosing of the first patient in the XMT-1592 clinical trial;
28

Table of Contents
an increase of $0.5 million related to manufacturing activities for XMT-1536;
an increase of $0.5 million related to research consulting and professional fees; and
an increase of $0.2 million related to advancement of companion diagnostic development efforts for the NaPi2B biomarker.
These increased costs were partially offset by the following:
a decrease of $1.3 million related to preclinical development and manufacturing activities for XMT-1592; and
a decrease of $1.0 million related to the development and manufacturing activities for XMT-1522.
We expect our research and development expenses to increase as we continue our clinical development of XMT-1536 and XMT-1592 and continue to advance our preclinical product candidate pipeline and invest in improvements in our ADC technologies.
General and Administrative Expense
General and administrative expense increased by $1.0 million from $4.2 million during the three months ended June 30, 2019 to $5.2 million during the three months ended June 30, 2020. The increase in general and administrative was primarily attributable to the following:
an increase of $0.6 million related to employee compensation, primarily due to the valuation of stock-based awards granted to employees, resulting in higher stock compensation expense; and
an increase of $0.4 million related to consulting and professional fees.
We expect that our general and administrative expense will increase in future periods as we expand our operations. These increases will likely include legal, auditing and filing fees, additional insurance premiums and general compliance and consulting expenses.
Total Other Income (Expense), net
Total other income (expense), net was immaterial and $0.7 million for the three months ended June 30, 2020 and 2019, respectively. Other income consists primarily of interest income on cash equivalents and short-term marketable securities. Interest expense related to our outstanding borrowings under the credit facility.

Collaboration Revenue
Collaboration revenue was $0.8 million during the six months ended June 30, 2020 and $41.2 million during the six months ended June 30, 2019. The decrease in collaboration revenue was primarily a result of the termination of the Takeda agreements and the recognition of the remaining deferred revenue of $40.0 million in the first quarter of 2019. During the six months ended June 30, 2020 revenue of $0.8 million was recognized as a result of completion of research services associated with a target included in the Merck KGaA Agreement. Additionally, during the six months ended June 30, 2019, collaboration revenue of $1.0 million was recognized related to the Merck KGaA Agreement and Merck KGaA Supply Agreement.
Research and Development Expense
Research and development expense decreased by $1.3 million from $28.9 million for the six months ended June 30, 2019 to $27.6 million for the six months ended June 30, 2020.
The decrease in research and development expense was primarily attributable to the following:
a decrease of $2.7 million related to preclinical development and manufacturing activities for XMT-1592 and finalization of the Dolasynthen platform;
a decrease of $1.7 million related to the development and manufacturing activities for XMT-1522;
a decrease of $1.0 million related to manufacturing activities for XMT-1536.
These decreased costs were partially offset by the following:
an increase of approximately $1.9 million related to XMT-1536 clinical and regulatory expenses;
an increase of approximately $0.9 million related to XMT-1592 clinical and regulatory expenses;
an increase of $0.8 million related to a milestone paid for dosing of the first patient in the XMT-1592 clinical trial; and
30

Table of Contents
an increase of $0.5 million related to advancement of companion diagnostic development efforts for the NaPi2B biomarker.
We expect our research and development expenses to increase as we continue our clinical development of XMT-1536 and XMT-1592 and continue to advance our preclinical product candidate pipeline and invest in improvements in our ADC technologies.
General and Administrative Expense
General and administrative expense increased by $1.5 million from $8.6 million during the six months ended June 30, 2019 to $10.1 million during the six months ended June 30, 2020. The increase in general and administrative was primarily attributable to the following:
an increase of $0.8 million related to employee compensation, primarily due to the valuation of stock-based awards granted to employees, resulting in higher stock compensation expense; and
an increase of $0.7 million related to consulting and professional fees.
We expect that our general and administrative expense will increase in future periods as we expand our operations. These increases will likely include legal, auditing and filing fees, additional insurance premiums and general compliance and consulting expenses.
Total Other Income (Expense), net
Total other income (expense), net was $0.2 million and $1.1 million for the six months ended June 30, 2020 and 2019, respectively. Other income consists primarily of interest income on cash equivalents and short-term marketable securities. Interest expense was related to our outstanding borrowings under the credit facility.
Liquidity and Capital Resources
Sources of Liquidity
Since our initial public offering in July 2017, we have financed our operations primarily with the proceeds from our initial public offering, our follow-on public offerings and use of our ATM program. We completed a follow-on public offering on March 5, 2019 that resulted in net proceeds of $92.2 million. On May 8, 2019, we entered into a term-loan agreement for up to $20.0 million, of which $5.0 million has been funded in connection with the execution of the agreement. No additional amounts have been drawn since the initial $5.0 million.
In April 2020, we sold approximately 10.9 million shares of common stock and received net proceeds of $63.0 million pursuant to our 2018 ATM. In addition, in June 2020, we sold 9.2 million shares of common stock in a follow-on offering and received net proceeds of approximately $164.0 million.
We terminated the 2018 ATM on April 9, 2020. On May 8, 2020, we established a new ATM pursuant to which we are able to sell $100.0 million of our common stock from time to time at prevailing market prices. As of June 30, 2020, we had not sold any shares under the ATM and had $100.0 million of availability under the program.
As of June 30, 2020, we had cash, cash equivalents and marketable securities of $291.4 million.

Net Cash Used in Operating Activities
Net cash used in operating activities was $37.2 million for the six months ended June 30, 2020 and primarily consisted of a net loss of $36.7 million adjusted for changes in our net working capital and other non-cash items including stock-based compensation of $3.3 million and depreciation of $0.5 million. Net cash used in operating activities was $38.9 million for the six months ended June 30, 2019 and primarily consisted of a net income of $4.8 million adjusted for non-cash items including the decrease in deferred revenue of $40.7 million primarily related to the Takeda agreements, stock-based compensation of $2.3 million and depreciation of $0.7 million, as well as change in our net working capital.
Net Cash Provided by (Used in) Investing Activities
Net cash provided by investing activities was $34.4 million during the six months ended June 30, 2020 and consisted primarily of maturities of marketable securities. Net cash used in investing activity was $2.0 million during the six months ended June 30, 2019 and consisted primarily of maturities of marketable securities and purchases of marketable securities.
Net Cash Provided by Financing Activities
Net cash provided by financing activities was $228.8 million during the six months ended June 30, 2020 as compared to net cash provided by financing activities of $97.5 million during the six months ended June 30, 2019. During the six months ended June 30, 2020 cash provided by financing activities consisted primarily of $164.2 million related to the follow-on public offering in May 2020 and the proceeds from the use of the ATM of $63.1 million in April 2020 as well as proceeds from exercise of stock options of $1.4 million, offset by the payment of $0.2 million of debt issuance costs. During the six months ended June 30, 2019 cash provided by financing activities consisted primarily of the proceeds from the our follow-on public offering.
Funding Requirements
We expect our cash expenditures to increase in connection with our ongoing activities, particularly as we continue the research and development of, initiate clinical studies of, and seek marketing approval for our product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to drug sales, marketing, manufacturing and distribution to the extent that such sales, marketing and distribution are not the responsibility of potential collaborators.
We believe our currently available funds will be sufficient to fund our existing cash flow requirements and our current operating plan commitments for more than two years. Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors. We have based this estimate on
32

Table of Contents
assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. Our future capital requirements will depend on many factors, including:
the scope, progress, results and costs of drug discovery, preclinical development, laboratory testing and clinical studies for our product candidates;
the scope, prioritization and number of our research and development programs;
the costs, timing and outcome of regulatory review of our product candidates;
our ability to establish and maintain collaborations on favorable terms, if at all;
the achievement of milestones or occurrence of other developments that trigger payments under any collaboration agreements we obtain;
the extent to which we are obligated to reimburse, or entitled to reimbursement of, clinical study costs under future collaboration agreements, if any;
the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;
the extent to which we acquire or in-license other product candidates and technologies;
the costs of securing manufacturing arrangements for clinical and commercial production; and
the costs of establishing or contracting for sales and marketing capabilities if we obtain regulatory approvals to market our product candidates.
Identifying potential product candidates and conducting preclinical testing and clinical studies is a time-consuming, expensive and uncertain process that takes many years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve drug sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of drugs that we do not expect to be commercially available for many years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all.
Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, strategic partnerships and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interests of our common stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. We have access to an additional line of credit of $15.0 million under the Credit Facility along with funds to be earned in connection with our agreements with Merck KGaA and Asana BioSciences, if development activities are successful under those agreements. Future additional debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.
If we raise funds through additional strategic partnerships or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our drug development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Off-Balance Sheet Arrangements
We did not have, during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under applicable Securities and Exchange Commission rules.
Critical accounting policies and significant judgments and estimates
Our management's discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make judgments and estimates that affect the reported amounts of assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events, and various other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. On an ongoing basis, we evaluate our judgments and estimates in light of changes in circumstances, facts and experience. The effects of material revisions in estimates, if any, will be reflected in the financial statements prospectively from the date of change in estimates. There were no material changes to our critical accounting policies as reported in our Annual Report on Form 10-K for the year ended December 31, 2019, which was filed with the SEC on February 28, 2020.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
We are exposed to market risk-related to changes in interest rates. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because our investments, including cash equivalents and marketable securities are invested in U.S. Treasury obligations, commercial paper and corporate bonds. However, we believe that due to the short-term duration of our investment portfolio and low-risk profile of our investments, an immediate 100 basis points change in interest rates would not have a material effect on the fair market value of our investments portfolio.
We are currently not exposed to market risk related to changes in foreign currency exchange rates, but we may contract with vendors that are located in Asia and Europe and may be subject to fluctuations in foreign currency rates at that time.
Item 4. Controls and Procedures
Management’s Evaluation of our Disclosure Controls and Procedures
We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act), that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to our management, including our principal executive and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their control objectives.
Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2020, the end of the period covered by this Quarterly Report on Form 10-Q. Based upon such evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of such date.

Item 1. Legal Proceedings
From time to time, we may be subject to various legal proceedings and claims that arise in the ordinary course of our business activities. Although the results of litigation and claims cannot be predicted with certainty, as of the date of this Quarterly Report on Form 10-Q, we do not believe we are party to any claim or litigation, the outcome of which, if determined adversely to us, would individually or in the aggregate be reasonably expected to have a material adverse effect on our business. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

ARTICLE 8

8.1Indemnification by MERSANA. MERSANA shall indemnify, hold harmless, and defend SNFX and its Representatives (“SNFX Indemnitees”) from and against any and all Third Party claims, suits, losses, liabilities, damages, costs, fees and expenses (including reasonable attorneys’ fees) (collectively, “Losses”) finally awarded to a Third Party by a court of competent jurisdiction or agreed to in a settlement approved by MERSANA that results from any claim made or brought against a SNFX Indemnitee by or on behalf of such Third Party, and subject to Section 8.3, any direct out-of-pocket costs and expenses (including reasonable attorneys’ fees) (“Litigation Costs”) incurred by a SNFX Indemnitee while investigating or conducting the defense of such Third Party claim, in any such case, solely to the extent such claim is directly based on or directly arises out of (a) the breach by MERSANA of any representation, warranty or covenant contained in this CLOA, (b) the negligence or willful misconduct of MERSANA or its Representatives or Sublicensees in connection with the performance of MERSANA’s obligations in this CLOA, (c) any actual violation by MERSANA of applicable Laws in the Development, Manufacture, Commercialization or Exploitation of any Product, (d) the Development, Manufacturing and/or Commercialization of a Product by
34



Exhibit 10.1

MERSANA or its Affiliates or Sublicensees (including product liability) in the Territory, and/or (e) the Development, Manufacture, Commercialization or Exploitation of any Product that infringes any Patent or misappropriates any Know-How owned or possessed by any Third Party (except to the extent no such infringement or misappropriation would occur but for the practice of the Licensed Technology); provided, however, that such indemnification right shall not apply to any Losses or Litigation Costs for which SNFX is obligated to indemnify MERSANA under Section 8.2.
8.2Indemnification by SNFX. SNFX shall indemnify, hold harmless, and defend MERSANA and its Representatives (“MERSANA Indemnitees”) from and against any and all Losses finally awarded to a Third Party by a court of competent jurisdiction or agreed to in a settlement approved by SNFX that result from any claim made or bought against an MERSANA Indemnitee by or on behalf of such Third Party, and subject to Section 8.3, any Litigation Costs incurred by a MERSANA Indemnitee while investigating or conducting the defense of such Third Party claim, in any such case, solely to the extent such claim is directly based on or directly arises out of (a) the breach by SNFX of any representation, warranty or covenant contained in this CLOA, (b) the negligence or willful misconduct of SNFX or its Representatives or sublicensees in connection with the performance of SNFX’s obligations in this CLOA, (c) any actual violation by SNFX of applicable Laws in its performance of its obligations in this CLOA, and/or (d) any action or omission of the Agent in performing its obligations under or in connection with this CLOA; provided, however, that such indemnification right shall not apply to any Losses or litigation costs for which MERSANA is obligated to indemnify SNFX under Section 8.1.
8.3Procedure. In the event of any such claim against any MERSANA Indemnitee or SNFX Indemnitee (individually, an “Indemnitee”), such Indemnitee shall promptly notify the other Party (the “Indemnifying Party”) in writing of the claim and the Indemnifying Party shall manage and control, at its sole expense, the defense of the claim and its settlement; provided that the failure to so notify promptly shall not relieve the Indemnifying Party of its obligations under this Article 8 except to the extent of the actual prejudice suffered by such Indemnifying Party as a result of such failure. The Indemnitee shall cooperate with the Indemnifying Party and may, at its option and expense, be represented in and participate in any such action or proceeding. The Indemnifying Party shall not be liable for any settlements, litigation costs or expenses incurred by any Indemnitee without the Indemnifying Party’s written authorization. Notwithstanding the foregoing, if the Indemnifying Party believes that any of the exceptions to its obligation of indemnification of the Indemnitees set forth in Section 8.1 or Section 8.2 may apply, the Indemnifying Party shall promptly notify the Indemnitees, which shall then have the right to be represented in any such action or proceeding by separate counsel at their expense; provided that the Indemnifying Party shall be responsible for payment of such expenses if the Indemnitees are ultimately determined to be entitled to indemnification from the Indemnifying Party. The Indemnifying Party shall not effect any settlement of any such claims without the consent of the Indemnitee, which consent shall not be unreasonably withheld or delayed, unless such settlement involves only the payment of money and includes a complete and unconditional release of the Indemnified Party from all liability with respect thereto.

Each Party shall procure and maintain insurance, or shall self-insure, in each case, in a manner adequate to cover its obligations hereunder and consistent with normal business practices of prudent companies similarly situated at all times during which any Product is being Developed, Manufactured, Commercialized or otherwise Exploited hereunder. Each Party shall procure insurance or self-insure at its own expense. Such insurance does not create a limit on either Party’s liability with respect to its indemnification obligations under this Article 8. Each Party shall provide the other Party with written evidence of such insurance or self-insurance upon request. Each Party shall provide the other Party with written notice at least [***] days before the cancellation or non-renewal of such insurance.
ARTICLE 9
LIMITATION OF LIABILITY
9.1LIMITATION. EXCEPT FOR ANY LOSSES THAT RESULT FROM A BREACH OF THE CONFIDENTIALITY OBLIGATIONS IN ARTICLE 6 OR ARE SUBJECT TO INDEMNIFICATION UNDER ARTICLE 8, OR LIABILITY THAT IS THE CONSEQUENCE OF GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF A PARTY, IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR ANY SPECIAL, CONSEQUENTIAL, EXEMPLARY OR INCIDENTAL DAMAGES (INCLUDING LOST OR ANTICIPATED REVENUES OR PROFITS RELATING TO THE SAME), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY ARISING OUT OF THIS CLOA, WHETHER SUCH CLAIM IS BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE) OR OTHERWISE, AND WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. THIS ARTICLE 9 SHALL NOT BE CONSTRUED TO LIMIT EITHER PARTY’S OBLIGATIONS UNDER ARTICLE 8.
ARTICLE 10
TERM AND TERMINATION
10.1Term. This CLOA shall commence on the Effective Date and, on a country-by-country and Licensed Target-by-Licensed Target basis, and, unless earlier terminated pursuant to this Article 10, shall remain in effect until the last to expire of any Royalty Term for each Product against a Licensed Target in such country (the “Term”).
10.2Termination.
(a)For Convenience. MERSANA shall have the right, at any time, to terminate this CLOA in its entirety or on a Licensed Target-by-Licensed Target basis (in the event of termination of this CLOA on a Licensed Target-by-Licensed Target basis pursuant to this Section 10.2(a) or Section 10.2(b), each such terminated Licensed Target, a “Terminated Target”) by providing not less than [***] days’ prior written notice to SNFX of such termination.
(b)For Material Breach. If either Party shall at any time breach any material term, condition or agreement herein, and shall fail to have cured any such default or breach within [***] days (or [***] days if such default or breach is the non-payment of any amounts due hereunder) (such period, the “Notice Period”) after receipt of written notice thereof
36



Exhibit 10.1
CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY [***], HAS BEEN OMITTED BECAUSE IT IS NOT MATERIAL AND WOULD LIKELY CAUSE COMPETITIVE HARM TO MERSANA THERAPEUTICS, INC. IF PUBLICLY DISCLOSED
by the other Party, then the other Party may, at its option, terminate this CLOA; provided that, in the event such an uncured breach by either Party relates only to one or more, but not all, of the Licensed Targets, the non-breaching Party shall only have the right to terminate this Agreement with respect to such Licensed Target(s); provided further, that the non-breaching Party shall have the right to terminate this Agreement in its entirety in the event that such an uncured breach by the other Party relates to at least [***] of the Licensed Targets; provided further, that if a breach is unrelated to any payment obligations hereunder and cannot be cured within the Notice Period but the breaching Party commences actions to cure such breach within the Notice Period, the Notice Period will be extended for an additional [***] days so long as the breaching Party thereafter diligently continues such actions; and provided further that if either Party initiates a dispute resolution procedure under Section 11.11 to resolve the dispute for which termination is being sought during the Notice Period, the Notice Period will be tolled and the termination will become effective only if such breach remains uncured for [***] days after the final resolution of the dispute through such dispute resolution procedure (or, if the breach is unrelated to any payment obligations hereunder and cannot be cured within such [***] day period after such final resolution, such period to cure such breach will be extended for a subsequent [***] day period so long as the breaching Party diligently continues such actions to cure such breach). Any termination of this CLOA under this Section 10.2 shall not, however, prejudice the right of the Party who terminates this CLOA to recover any payment due at the time of such termination.
(c)For Bankruptcy. Either Party may terminate this CLOA upon the occurrence of one or more of the following: (i) immediately upon written notice to the other Party in the event the other Party is insolvent or initiates a voluntary proceeding under any applicable bankruptcy Law or code; or (ii) immediately upon written notice to the other Party in the event the other Party becomes the subject of an involuntary proceeding under any applicable bankruptcy Law or code and such proceeding is not dismissed or stayed within [***] days of its commencement.
(d)Patent Challenge. SNFX may terminate this CLOA in its entirety upon [***] days’ written notice to MERSANA in the event MERSANA, or any of its Affiliates or Sublicensees, challenges in a legal or administrative proceeding the validity or enforceability of a Valid Claim of any Licensed Patent (except as (i) required under a court order or subpoena or (ii) a defense against a claim, action or proceeding asserted by SNFX against MERSANA or any of its Affiliates or Sublicensees); provided that any such termination shall not become effective if (A) such action has been withdrawn before the end of the aforementioned notice period and/or (B) in the event that the challenging party is a Sublicensee of MERSANA, MERSANA terminates such Sublicensee’s Sublicense to the challenged Licensed Patent before the end of the aforementioned notice period. In addition, if the Valid Claim of a Licensed Patent is upheld, MERSANA shall reimburse SNFX for its reasonable legal costs and expenses incurred in defending any such challenge.
10.3Effect of Expiration or Termination.
(a)Rights and Obligations Upon Expiration or Termination.

(1)Upon expiration or termination of this CLOA, neither Party shall have any further rights or obligations hereunder in the Territory with respect to the Terminated Targets or under this CLOA in its entirety, as applicable, except pursuant to any provisions hereunder that expressly survive such expiration or termination (including, for the avoidance of doubt, this Section 10.3).
(2)Upon the date of expiration (but not earlier termination) of each Royalty Term with respect to all Products with respect to a Licensed Target in a country, the rights and licenses granted by SNFX or its Affiliates to MERSANA and its Affiliates under this CLOA to Develop, Manufacture, Commercialize and otherwise Exploit Products against such Licensed Target in the Field throughout the Territory shall convert to irrevocable, perpetual, non-exclusive, royalty-free, fully paid-up, freely transferable, non-terminable rights and licenses, with the right to grant sublicenses (through multiple tiers), with no further obligation to SNFX.
(3)In the event of any termination by MERSANA pursuant to Sections 10.2(b) or 10.2(c), the rights and licenses granted by SNFX or its Affiliates to MERSANA and its Affiliates under this CLOA to Develop, Manufacture, Commercialize and otherwise Exploit Products against a Licensed Target in the Field throughout the Territory shall convert to irrevocable, perpetual, non-exclusive, freely transferable, non-terminable rights and licenses, with the right to grant sublicenses (through multiple tiers), subject to the continued payment by MERSANA of all amounts due to SNFX pursuant to Article 3 during the applicable Royalty Term in a country;
(4)In the event of any termination by SNFX pursuant to Sections 10.2(b), 10.2(c), or 10.2(d) or MERSANA terminates pursuant to Section 10.2(a), as of the effective date of such termination of this CLOA:
(i) this CLOA and all rights and licenses granted to MERSANA under Sections 2.1, 2.2 and 4.4(a) shall terminate with respect to the Terminated Targets or with respect to all Licensed Targets, as applicable, and all such applicable rights in the Licensed Technology shall revert to SNFX; and
(ii) except as required for a Party to exercise its rights or fulfill its obligations under this Section 10.3, each Party shall return to the other Party or destroy (at the disclosing Party’s option) and cease using all Confidential Information of the other Party (including, for the avoidance of doubt, the Licensed Know-How and all copies thereof) that are solely related to the Terminated Targets or with respect to all Confidential Information if this CLOA is terminated in its entirety, as applicable; provided, however, each Party may retain one (1) copy of such Confidential Information for archival purposes. Each Party shall confirm in writing to the other Party that all such Confidential Information, except one (1) copy for archival purposes, has been returned to the other Party. Notwithstanding the foregoing, the obligation to return Confidential Information shall not cover information that is required to be retained by applicable Law or information maintained on routine computer system backup tapes, disks or other backup storage devices as long as such backed-up information is not used, disclosed or otherwise recovered from such backup devices.

(b)Accrued Rights. Termination of this CLOA for any reason will be without prejudice to any rights that will have accrued to the benefit of a Party prior to such termination. Such termination will not relieve a Party from accrued payment obligations or from obligations which are expressly indicated to survive termination of this CLOA.
(c)Survival. The provisions of Sections 2.1(a) (to the extent set forth in Section 10.3(a)(2) and 10.3(a)(3)), 2.8, 2.9, 5.1, 5.2, 5.3, 10.3 and Article 1, Article 3 (to the extent set forth in Section 10.3(a)(3)), Article 6, Article 7, Article 8, Article 9 and Article 11 shall survive expiration or termination of this CLOA for the period so specified, if any, or for perpetuity.
ARTICLE 11
GENERAL PROVISIONS
11.1Entire Agreement. The Parties acknowledge that this CLOA, together with the exhibits and schedules attached hereto, sets forth the entire agreement and understanding of the Parties as to the subject matter hereof, and supersedes all prior and contemporaneous discussions, agreements and writings in respect hereto, except for the Material Transfer Agreement which shall remain in full force and effect between SNFX and MERSANA, and the Three-way Mutual Non-Disclosure Agreement which shall remain in full force and effect between SNFX, MERSANA and Me Jean-Paul Vulliety. To the extent there is any conflict or ambiguity between this CLOA and the Material Transfer Agreement (or any amendments thereto that may be agreed in the future between the Parties), this CLOA shall control. To the extent there is any conflict or ambiguity between this CLOA and the Three-way Mutual Non-Disclosure Agreement (or any amendments thereto that may be agreed in the future between the parties thereto), the Three-way Mutual Non-Disclosure Agreement shall control.
11.2Modification; Waiver. No waiver, modification, amendment or alteration of any provision of this CLOA will be valid or effective unless made in writing and signed by each of the Parties. The failure of a Party to enforce any rights or provisions of the CLOA shall not be construed to be a waiver of such rights or provisions, or a waiver by such Party to thereafter enforce such rights or provisions or any other rights or provisions hereunder.
11.3Further Assurances. Each Party agrees to execute, acknowledge, and deliver such further instruments and to do all such other acts as may be necessary or appropriate in order to carry out the express provisions of this CLOA.
11.4Force Majeure. Neither Party shall be held responsible for any delay or failure in performance hereunder caused by strikes, embargoes, unexpected government requirements, civil or military authorities, acts of God, earthquake, terrorism, or by the public enemy or other causes reasonably beyond such Party’s control and without such Party’s fault or negligence; provided that the affected Party notifies the unaffected Party as soon as reasonably possible, and resumes performance hereunder as soon as reasonably possible following cessation of such force majeure event.

11.5Assignments. A Party shall not have the right to assign, by operation of law or otherwise, any of its rights or obligations under this CLOA without the prior written consent of the other Party, which consent shall not be unreasonably withheld, except that either Party may assign or transfer this CLOA in its entirety, without the written consent of the other Party, (a) to any successor in interest that acquires all or substantially all of the business or assets of a Party or that portion of the business or assets of such Party pertaining to the subject matter of this CLOA (whether by merger, reorganization, acquisition, consolidation, sale or otherwise) or (b) to its Affiliate; provided that any permitted assignee will assume all rights and obligations of its assignor under this CLOA. Any assignment not in accordance with this Section 11.5 will be null and void.
11.6Performance by Affiliates. The Parties recognize that each may perform some or all of its obligations under this CLOA through its Affiliates or may exercise some or all of its rights under this CLOA through its Affiliates; provided, however, that each Party shall remain responsible and be the guarantor of the performance by its Affiliates and shall cause its Affiliates to comply with the provisions of this CLOA in connection with such performance. In particular and without limitation, all Affiliates of a Party that receive Confidential Information of the other Party pursuant to this CLOA shall be governed and bound by all obligations set forth in Article 6. Each Party will prohibit all of its Affiliates from taking any action that such Party is prohibited from taking under this CLOA as if such Affiliates were parties to this CLOA.
11.7Relationship of the Parties. The Parties shall perform their obligations under this CLOA as independent contractors and nothing in this CLOA is intended or will be deemed to constitute a partnership, agency, joint venture or employer-employee relationship between the Parties. Neither Party will have any right, power or authority to assume, create, or incur any expense, liability, or obligation, express or implied, on behalf of the other.
11.8No Third Party Beneficiaries. Except for the rights to indemnification provided for under Article 8 above, all rights, benefits and remedies under this CLOA are solely intended for the benefit of MERSANA and SNFX, and except for such rights to indemnification expressly provided pursuant to Article 8, no Third Party shall have any rights whatsoever to: (a) enforce any obligation contained in this CLOA; (b) seek a benefit or remedy for any breach of this CLOA; or (c) take any other action relating to this CLOA under any legal theory, including actions in contract, tort (including negligence, gross negligence and strict liability), or as a defense, setoff or counterclaim to any action or claim brought or made by the Parties.
11.9No Use of Names. Except as otherwise required under applicable Law or permitted under this CLOA, neither Party will use the name, logo or trademark of the other Party or any of its Affiliates or any of its or their Sublicensees in its advertising, press releases or marketing or promotional materials without the prior written consent of such other Party.
11.10Notices. Any notice, request, delivery, approval or consent required or permitted to be given under this CLOA will be in writing and will be deemed to have been sufficiently given if delivered in person (in which case, it will be effective upon delivery), transmitted by facsimile, if facsimile number is provided below (receipt verified; in which case, it will be effective upon delivery), by express courier service (signature required; in which case, it will be

11.11Dispute Resolution. The Parties agree that any disputes arising with respect to the interpretation, enforcement, termination or invalidity of this CLOA (each, a “Dispute”) shall first be presented to the Parties’ respective Executive Officers for resolution. If the Parties are unable to resolve a given Dispute pursuant to this Section 11.11 after discussions between the Executive Officers within ten (10) days after referring such Dispute to the Executive Officers, either Party may, at its sole discretion, seek resolution of such matter in accordance with Section 11.12.
11.12Submission to Court for Resolution. Subject to Section 11.11, the Parties hereby irrevocably and unconditionally consent to the exclusive jurisdiction of the courts located in the Southern District of New York for any action, suit or proceeding (other than appeals therefrom) arising out of or relating to this CLOA, and agree not to commence any action, suit or proceeding (other than appeals therefrom) related thereto except in such courts. The Parties further hereby irrevocably and unconditionally waive any objection to the laying of venue of any action, suit or proceeding (other than appeals therefrom) arising out of or relating to this CLOA in the courts of New York, and hereby further irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such action, suit or proceeding brought in any

Exhibit 10.1

such court has been brought in an inconvenient forum. Each Party further agrees that service of any process, summons, notice or document by registered mail to its address set forth in Section 11.10 shall be effective service of process for any action, suit or proceeding brought against it under this CLOA in any such court.
11.13Governing Law. This CLOA and all questions regarding its validity or interpretation, or the performance or breach of this CLOA, shall be governed by and construed and enforced in accordance with the laws of the State of New York and the Federal laws of the United States of America, without reference to conflicts of laws principles.
11.14Headings. The article, section and subsection headings contained herein are for the purposes of convenience only and are not intended to define or limit the contents of the articles, sections or subsections to which such headings apply.
11.15Severability. When possible, each provision of this CLOA will be interpreted in such manner as to be effective and valid under applicable Law, but, if any provision of this CLOA is held to be prohibited by or invalid under applicable Law, such provision will be ineffective but only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or of this CLOA. The Parties will make a good faith effort to replace the invalid or unenforceable provision with a valid one which in its economic effect is most consistent with the invalid or unenforceable provision.
11.16Equitable Relief. Nothing contained in this CLOA will deny any Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of prospective irreparable harm.
11.17Counterparts. This CLOA may be executed in two (2) or more counterparts (including by facsimile or electronic signature), each of which shall be deemed an original and all of which together shall constitute one instrument.
