The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the condensed consolidated financial statements and notes to the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. This discussion and analysis contains forward-looking statements based upon current beliefs, plans and expectations that involve risks, uncertainties and assumptions, such as statements regarding our plans, objectives, expectations, intentions and projections. Our actual results and the timing of events could differ materially from those anticipated in these forward-looking statements as a result of several factors that could impact our business, including those set forth in the section titled "Risk Factors" under Part II, Item 1A in this Quarterly Report on Form 10-Q. In some cases, you can identify forward-looking statements by terminology such as "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "plan," "potentially," "predict," "should," "will" or the negative of these terms or other similar expressions. In addition, statements that "we believe" and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report on Form 10-Q, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate we have conducted exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements. Overview of Our Business We are a biopharmaceutical company focused on discovering and developing novel therapeutics based on scientific understanding of key biological pathways underlying retinal diseases, cancer, and liver and metabolic diseases. These diseases represent a significant burden for patients and healthcare systems and, in some cases, are leading causes of morbidity and mortality. Our strategy is to leverage a combination of interrogating human biology and engineering powerful biologics to discover and develop promising product candidates and seek to move them rapidly into proof-of-concept studies and late-stage development, with the goal of delivering impactful first-in-class or best-in-class treatments to underserved patients suffering from grievous diseases. Since the commencement of our operations in 2008, we have generated a robust portfolio of product candidates ranging from early discovery to late-stage development. We aspire to operate one of the most productive research and development engines in the biopharmaceutical industry. Merck Collaboration Update OnJune 30, 2021 , we andMerck Sharp & Dohme Corp. , or Merck, entered into an amended and restated research collaboration, product development and license agreement, or the Amended Collaboration Agreement, that amends and restates the research collaboration, product development and license agreement that we originally entered into with Merck inFebruary 2015 , which, together with amendments made prior to entering into the Amended Collaboration Agreement, we refer to as the Original Agreement. The Original Agreement contemplated an initial five-year research term and, inMarch 2019 , Merck exercised its option to extend the research phase of the collaboration throughMarch 16, 2022 . As part of that extension, Merck agreed to continue to fund up to$75.0 million of our research and development efforts each year consistent with the initial five-year research term and, in lieu of a$20.0 million extension fee payable to us, Merck agreed to make additional payments totaling up to$20.0 million in support of our research and development activities during 2021 through the first quarter of 2022. Under the terms of the Amended Collaboration Agreement, we and Merck agreed to extend the research phase of the collaboration with a narrower scope than contemplated in the Original Agreement. The research phase will now continue generally throughMarch 31, 2024 , with possible extensions for each of the various programs to allow us or Merck to complete ongoing development. Under the Original Agreement, all of our research and development programs, both those existing at the time we entered into the Original Agreement and those we worked on during the research phase of the collaboration, other than aldafermin, were included within the scope of the collaboration. Under the Amended Collaboration Agreement, the scope of the collaboration and the resulting programs for which Merck has a license option was narrowed. The collaboration as now being conducted under the Amended Collaboration Agreement, or the continuing collaboration, focuses primarily on the identification, research and development of collaboration compounds directed to targets of interest to Merck in the fields of ophthalmology and cardiovascular or metabolic, or CVM, disease, including heart failure, as well as certain laboratory testing and other activities on molecules that are directed to one of up to two undisclosed targets outside of the fields of ophthalmology and CVM disease, referred to 26 -------------------------------------------------------------------------------- as the lab programs. The ophthalmology compounds in the continuing collaboration include NGM621 and its related molecules and compounds directed against two other undisclosed ophthalmology targets and their related molecules. Collaboration compounds that remain within the scope of the continuing collaboration under the Amended Collaboration Agreement are referred to as continuing collaboration compounds. Our and Merck's rights and obligations with respect to MK-3655 and related FGFR1c/KLB agonists for which Merck exercised its license option inNovember 2018 under the Original Agreement did not change under the Amended Collaboration Agreement as compared to the Original Agreement. Merck retains the one-time option to obtain an exclusive, worldwide license, on specified terms, to continuing collaboration compounds, as well as to other molecules that are directed against the same target and that result in the same effect on such target, or the related molecules, upon completion of a human proof-of-concept trial for a particular collaboration compound, regardless of the results of such trial, or at earlier points as specified in the Amended Collaboration Agreement, including the option to license NGM621 upon completion of a human proof-of-concept trial in humans, as well as the additional one-time option at that time to license NGM621 together with all of the ophthalmology continuing collaboration compounds included within the scope of the Amended Collaboration Agreement. All such options to license are referred to as Merck license options. Under the Amended Collaboration Agreement, we now have the sole right, in our sole discretion to independently research, develop and commercialize our oncology product candidates NGM120, NGM707 and NGM438 and their related molecules and all other preclinical and research assets that we researched or developed under the Original Agreement but that are not included within the research and development scope of the continuing collaboration, which we refer to as the released NGM compounds, subject to Merck's right to receive royalties at low single digit rates on any released NGM compounds that receive regulatory approval and, if we decide during a certain time period to engage in a formal partnering process or negotiations regarding a license or asset sale for a released NGM compound, to a requirement to notify Merck, provide Merck with certain information and engage in good faith, non-exclusive negotiations with respect to such released NGM compound with Merck at Merck's request. We are generally responsible for funding released NGM compounds going forward, although we may use Merck funding for research and development activities that we perform on these compounds prior toApril 1, 2022 . We also have full rights to all future programs we pursue that fall outside of the scope of the Amended Collaboration Agreement. Aldafermin remains wholly owned and funded by us. Under the terms of the Amended Collaboration Agreement, Merck will provide an aggregate of approximately$120.0 million in research and development funding throughMarch 31, 2024 , including$86.0 million for the period fromApril 1, 2021 throughMarch 31, 2022 (although we are obligated to use commercially reasonable efforts to expend$35.0 million of such funding during such time frame on programs within the scope of the continuing collaboration other than the released NGM compounds), plus additional potential option payments if Merck exercises any Merck license option. We are committed to advancing an undisclosed ophthalmology program to a potential investigational new drug application, or IND, submission, utilizing our own funding afterMarch 2022 . After Merck has exercised the Merck license option for a continuing collaboration program and paid the applicable option fee, the economics for such program are unchanged from the Original Agreement. Following exercise of a Merck license option, Merck is responsible, at its own cost, for any further development and any commercialization activities for compounds within the applicable program that it licensed, or the licensed compounds, subject to our option on a licensed compound-by-licensed compound basis, prior to Merck initiating any Phase 3 clinical trial of such licensed compound, to enter into a worldwide cost and profit share with Merck. If we do not elect to exercise our cost and profit share option for a particular licensed compound, we are eligible to receive milestone and royalty payments. Similar to the Original Agreement, during the research phase and any applicable tail period of the continuing collaboration, we may not directly or indirectly research, develop, manufacture or commercialize, outside of the continuing collaboration, any product with specified activity against any target that is being researched or developed under the continuing collaboration and, if Merck exercises its Merck license option for a program, we may not directly or indirectly research, develop, manufacture or commercialize any product with specified activity against the target that is the subject of that program for so long as Merck's license to it remains in effect. In addition, under the Amended Collaboration Agreement, we are prohibited from directly or indirectly researching, developing or commercializing any product for the treatment of heart failure with preserved ejection fraction (HFpEF) during the research phase for the CVM-related programs. For more information on the terms of the Amended Collaboration Agreement, see Note 5, "Research Collaboration and License Agreements," of the notes to unaudited condensed consolidated financial statements included in Part 1 Item 1 of this Quarterly Report on Form 10-Q. 27 -------------------------------------------------------------------------------- Pipeline Programs and Operations Updates We currently have five product candidates in the clinic, including four Phase 2 and Phase 2b programs, two wholly owned by us (NGM120 and aldafermin), one being progressed by Merck (MK-3655) and one optionable by Merck (NGM621), and one in the Phase 1 component of a Phase 1/2 trial (NGM707). In addition, we have one wholly owned product candidate expected to enter the clinic in the first half of 2022. •Retinal diseases. •NGM621. NGM621 is a humanized Immunoglobulin 1, or IgG1, monoclonal antibody administered via intravitreal, or IVT, injection. NGM621 was engineered to potently inhibit the activity of complement C3 with the treatment goal of reducing disease progression in patients with geographic atrophy, or GA, secondary to age-related macular degeneration. NGM621 remains within the scope of the Amended Collaboration Agreement with Merck, and Merck has a one-time option to license NGM621 and its related molecules upon completion of the Phase 2 CATALINA clinical trial of NGM621 in patients with GA, as well as the additional one-time option at that time to license NGM621 together with all of the ophthalmology continuing collaboration compounds and their respective related molecules included within the scope of the Amended Collaboration Agreement. ?To date in 2021, we completed enrollment of 320 patients into the Phase 2 CATALINA clinical trial of NGM621 in patients with GA, more than the originally planned 240 patients. The CATALINA trial was designed to be a Phase 3-supportive or -enabling clinical trial and is evaluating NGM621's safety and effects on disease progression when given every four weeks or every eight weeks compared to matched sham injection control groups. ?Looking forward: We anticipate a readout of the CATALINA trial topline data in the second half of 2022. •Oncology. •NGM120. NGM120 is an antagonist antibody that binds glial cell-derived neurotrophic factor receptor alpha-like, or GFRAL, and inhibits growth differentiation factor 15, or GDF15, signaling, for the potential treatment of cancer and cancer-related cachexia. We are currently conducting a clinical trial to assess NGM120's effect on cancer-related cachexia and on cancer in patients with select advanced solid tumors and metastatic pancreatic cancer. ?To date in 2021, we initiated a Phase 2 placebo-controlled component of the ongoing Phase 1/2 PINNACLES clinical trial of NGM120 and are continuing enrollment into that trial. This Phase 2 portion of the trial is testing NGM120 in combination with gemcitabine and Abraxane® (paclitaxel protein bound) as first-line treatment in patients with metastatic pancreatic cancer to assess NGM120's effect on both cancer and cancer-related cachexia. ?Looking forward: In the third quarter of 2021, we expect to report interim data from two Phase 1 dose-finding cohorts of the ongoing Phase 1/2 trial of NGM120: a Phase 1a cohort evaluating NGM120 as a monotherapy in patients with select advanced solid tumors and a Phase 1b cohort evaluating NGM120 in combination with gemcitabine and Abraxane in patients with metastatic pancreatic cancer. •NGM707. NGM707 is a dual antagonist antibody that is designed to inhibit Immunoglobulin-like transcript 2, or ILT2 (also known as LILRB1), and Immunoglobulin-like transcript 4, or ILT4 (also known as LILRB2). ILT2 and ILT4 are key myeloid and lymphoid checkpoints that may restrict anti-tumor immunity, enable tumors to evade immune detection and contribute to resistance to T-cell checkpoint inhibitors. Designed to inhibit these key checkpoints, NGM707 has the potential to reverse myeloid suppression and further stimulate effector function activity. InJune 2021 , we initiated the Phase 1 component of a first-in-human Phase 1/2 clinical trial of NGM707, as a monotherapy and in combination with KEYTRUDA® (pembrolizumab), for the treatment of patients with advanced solid tumors and are continuing enrollment into that trial. •NGM438. NGM438 is an antagonist antibody that is designed to inhibit leukocyte-associated immunoglobulin-like receptor 1, or LAIR1. LAIR1, through interactions with tumor-associated collagens, may form a stromal checkpoint that imposes signaling-based immune suppression and impedes antitumor immunity. Designed to inhibit this stromal checkpoint, NGM438 has the potential to treat cancer by promoting the remodeling of the tumor architecture that restricts T cell infiltration of the tumor cell mass and reversing immune suppression in the tumor microenvironment. 28 -------------------------------------------------------------------------------- ?To date in 2021, we have advanced the preparation of an IND for a planned submission later in 2021 or in early 2022. ?Looking forward: We expect to commence a first-in-human Phase 1 clinical trial of NGM438 in patients with advanced solid tumors in the first half of 2022. •Liver and metabolic diseases. •Aldafermin. Aldafermin is an engineered analog of human hormone fibroblast growth factor 19, or FGF19, that is administered through a once-daily subcutaneous injection. Aldafermin is wholly owned by us. InMay 2021 , we announced topline results from our ALPINE 2/3 trial evaluating aldafermin in 171 patients with non-alcoholic steatohepatitis, or NASH, and liver fibrosis stage 2 or 3, or F2 or F3. The trial did not meet its primary endpoint evaluating a dose response at week 24 on liver fibrosis improvement by >1 stage with no worsening of NASH. The lack of statistically significant fibrosis improvement was unexpected given the consistency of histology findings seen with aldafermin in the fourth cohort of a previously completed Phase 2 trial. Although the trial did achieve statistical significance versus placebo on certain secondary endpoints, we have decided to shift resources that had previously been reserved for a Phase 3 F2/F3 NASH development program toward advancing our other programs. Aldafermin remains in Phase 2b development for the treatment of patients with compensated NASH cirrhosis (liver fibrosis stage 4, or F4). To date in 2021, in addition to completing treatment of patients in and announcing topline results from our ALPINE 2/3 trial, we have continued enrollment into our Phase 2b ALPINE 4 clinical trial of aldafermin, with a goal of enrolling approximately 150 patients across 80 sites inthe United States ,Europe , theUK ,Hong Kong andAustralia . •MK-3655 (formerly NGM313). MK-3655 is an agonistic antibody discovered by us that selectively activates fibroblast growth factor receptor 1c-beta-klotho, or FGFR1c/KLB, which regulates insulin sensitivity, blood glucose and liver fat and is administered every four weeks through a subcutaneous injection. MK-3655, in Phase 2b development for the treatment of NASH, was optioned by Merck under the Original Agreement. In 2021, Merck is continuing enrollment into the worldwide 52-week randomized, double-blind Phase 2b trial of MK-3655 in patients with NASH and F2 or F3 liver fibrosis that it initiated in the fourth quarter of 2020. We have additional undisclosed programs that are in various stages of development ranging from functional validation to preclinical development. The success of each of our product candidates may be affected by numerous factors, including preclinical data, clinical data, competition, manufacturing capability, sales capability, collaboration partners, the sufficiency of our cash resources, regulatory matters, third-party payor matters and commercial viability. We do not have any products approved for sale and do not anticipate generating revenue from product sales for the foreseeable future, if ever. Partnering has been and is expected to continue to be a component of our strategy as we plan to develop a broad portfolio of product candidates and, if approved, to commercialize the resulting products. Our collaboration with Merck under the Original Agreement has provided us with substantial financial support; however, under the narrower scope of the Amended Collaboration Agreement, afterMarch 2022 the level of research funding from Merck will be substantially lower on an annual and overall basis than the research funding provided by Merck prior to that date. As a result, our funding requirements for the development of our current and potential future product candidates will increase substantially afterMarch 2022 , particularly with respect to our wholly owned programs, and, to a lesser extent, with respect to our programs that are within the scope of the continuing collaboration under the Amended Collaboration Agreement that we are required to fund. In addition, our funding requirements would increase for any programs that are within the scope of the continuing collaboration in the event Merck does not elect to license these programs, in the event Merck elects to terminate its license to any program it licenses or in the event we opt to co-develop any Merck-licensed programs. Accordingly, we will require significant additional capital in order to proceed with the development through to regulatory approval and commercialization of our current and potential future product candidates, or we will need to enter into additional collaboration or license agreements in order to fund such development and commercialization. Neither may be possible and, as a result, we may be required to delay, scale back or discontinue development of such product candidates, which could have a material adverse effect on our business, operating results and prospects. For any programs wholly owned by us and not within the scope of the continuing collaboration, we may decide to pursue a strategic partner to progress, in whole or in part, the program or commercialize any resulting approved product. 29 -------------------------------------------------------------------------------- In addition, all of our manufacturing activities are outsourced to third-party contract development and manufacturing organizations or third-party contract manufacturing organizations, which we refer to collectively as CMOs, who are generally single source suppliers of the drug product or drug substance they are manufacturing for us. We also utilize third-party contract research organizations, or CROs, to carry out many of our clinical development activities. We expect to be reliant on CMOs and CROs for these activities for the foreseeable future. Significant portions of our research and development resources are focused, and will continue to be focused, on the manufacture of clinical trial materials. If our CROs and CMOs fail to satisfy their contractual duties to us or meet expected deadlines or if our CMOs experience difficulties in scaling production or procuring raw materials or components or experience product loss due to contamination, equipment failure, improper installation or operation of equipment, vendor or operator error, turnover of qualified staff or improper storage conditions, our ongoing and planned trials may be delayed, perhaps substantially, which could materially and adversely affect our business. We seek to allocate our capital efficiently and strategically and fund our portfolio based on each program's scientific and other merits. Our discipline has been demonstrated by our decision not to proceed with development activities on multiple potentially viable product candidates for portfolio management reasons, in order to concentrate our resources on what we consider our most promising product candidates. However, given the narrower scope of the Amended Collaboration Agreement and our associated increased funding requirements with respect to our development programs, particularly afterMarch 2022 , we may need to delay or suspend development activities on product candidates that we consider promising unless and until we are able to raise sufficient additional capital in order to proceed with such development through to regulatory approval. Financial Highlights Since inception, we have funded our operations primarily through: •fees received from collaboration partners, which since inception throughJune 30, 2021 includes reimbursement of research and development expenses of$446.8 million and upfront cash licensing fees of$123.0 million , primarily from Merck, and a payment of$20.0 million from Merck to license MK-3655 and related compounds; •proceeds from private placements of convertible preferred stock prior to our initial public offering, or IPO, including approximately$106.0 million of our Series E convertible preferred stock purchased by Merck; •net proceeds from our IPO in 2019 of approximately$107.8 million , together with proceeds from the concurrent private placement of shares of common stock to Merck of$65.9 million ; •net proceeds of$21.9 million from sales of 809,700 shares of our common stock at an average price of$27.94 per share inDecember 2020 under an Open Market Sale AgreementSM, or the Sales Agreement, we entered into withJefferies LLC , or Jefferies, inJune 2020 ; and •net proceeds of$134.6 million from the sale of 5,324,074 shares of our common stock inJanuary 2021 upon completion of an underwritten public offering of our common stock, or the follow-on offering, which included the full exercise by the underwriters of their option to purchase additional shares. AtJune 30, 2021 , we had$390.6 million in cash, cash equivalents and short-term marketable securities. We have incurred net losses each year since our inception. As ofJune 30, 2021 , we had an accumulated deficit of$362.9 million . Substantially all of our net losses have resulted from costs incurred in connection with our research and development, or R&D, programs and general and administrative costs associated with our operations. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials and our expenses on other R&D activities, and the amount of R&D funding we receive from Merck or other collaboration partners, particularly afterMarch 2022 . For further discussion of our financial position and future sources of funding, see "Liquidity and Capital Resources" below. COVID-19 Business Update We continue to closely monitor the impact of the global COVID-19 pandemic on our business and have taken and continue to take proactive efforts designed to protect the health and safety of our patients, study investigators, clinical research staff and employees, while maintaining business continuity. Following guidance from federal, state and local authorities, we continue to operate with a primarily remote work model. Employees working on site continue to be mostly those individuals conducting essential in-person laboratory work and other business functions considered essential under COVID-19 regulations and guidance. We are still allowing other individuals to work remotely. There have been relatively minor impacts on productivity overall, but future developments could more materially and adversely impact our productivity. In addition, in 2020 and to date in 2021, we have experienced higher-than-normal employee turnover and an increased rate of hiring new employees. We cannot predict whether these trends will continue or be exacerbated, when we will be permitted to, and whether we will, 30 -------------------------------------------------------------------------------- return to a fully office-based working model or a hybrid model, and the impacts of that decision, or whether we will be required to adopt a more restrictive work model as the pandemic evolves. For patients enrolled in our clinical trials, we continue to work closely with clinical trial investigators and site staff with the goal of continuing treatment in a manner designed to uphold trial integrity, while allowing some flexibility in the manner and timing of patient visits, and to observe government and institutional guidelines designed to safeguard the health and safety of patients, clinical trial investigators and site staff. We have experienced, from time to time, a slower pace of clinical trial site initiation and clinical trial enrollment than originally anticipated in certain of our clinical trials, including the ALPINE 4, CATALINA and NGM120 trials, and we experienced a higher dropout rate in our ALPINE 2/3 trial than we had anticipated based on our previous trials in patients with NASH. We believe this may be due to factors such as the vulnerability of our studied patient populations, clinical trial site suspensions, reallocation of medical resources and the challenges of working remotely due to shelter-in-place and similar government orders. We have been proactively working to mitigate these and other effects of the COVID-19 pandemic by monitoring site initiations, patient enrollment and patient study adherence to provide support to patients and trial staff, often on a casebycase and/or patient-by-patient basis. For example, we have implemented additional study policies and procedures designed to help protect trial participants from exposure to COVID-19 as a result of their trial participation, which include the use of telemedicine visits, remote monitoring of patients and clinical trial sites and other measures, as appropriate, designed to ensure that data from clinical trials that may be disrupted as result of the pandemic are collected pursuant to the study protocol and consistent with current Good Clinical Practices, with any material protocol deviation reviewed and approved by the clinical trial site institutional review board, or IRB. Most of our clinical trial sites, both within and outside ofthe United States , continue to screen patients in our clinical trials, and new patients are being enrolled when appropriate. While the COVID-19 pandemic has not yet resulted in a significant impact to our disclosed clinical development timelines, as the pandemic continues, there may be additional negative impacts on our ability to initiate new clinical trial sites, maintain enrollment of existing patients and enroll new patients, which may result in increased clinical trial costs and negatively impact our timelines and our ability to obtain regulatory approvals of our product candidates in a timely fashion, if at all. We also could see an adverse impact on our ability to report clinical trial results, or interact with regulators, IRBs and ethics committees or other important agencies due to limitations in health authority employee resources or otherwise. Moreover, we rely on CROs and other third parties to assist us with clinical development activities, and we cannot guarantee that they will continue to perform their contractual duties in a timely and satisfactory manner as a result of the COVID-19 pandemic. In addition, while we have not experienced significant disruption to drug or related component supply for our ongoing clinical trials, we could experience disruptions to our supply chain and operations due to the evolving effects of the continuing pandemic, including if our CMOs' manufacturing facilities and operations are adversely affected by labor and raw material shortages, turnover of qualified staff or financial difficulties of their owners or operators. Any associated delays in the manufacturing and supply of drug substance and drug product for our clinical trials could adversely affect our ability to conduct ongoing and future clinical trials of our product candidates. Our aldafermin drug product CMO has advised us that it could be required under orders of theU.S. government to allocate manufacturing capacity to the manufacture or distribution of COVID-19 vaccines. If any of our CMOs become subject to acts or orders ofU.S. or foreign government entities to allocate manufacturing capacity to the manufacture or distribution of COVID-19 vaccines or medical supplies needed to treat COVID-19 patients, this could also delay our clinical trials, perhaps substantially, which could materially and adversely affect our business. Finally, we cannot predict how the evolving effects of the COVID-19 pandemic may influence the future decisions of Merck to license any programs available to it under the Amended Collaboration Agreement. For additional information about risks and uncertainties related to the COVID-19 pandemic that may impact our business, financial condition and results of operations, see the section titled "Risk Factors" in Part II, Item 1A of this Quarterly Report on Form 10-Q. Financial Operations Overview Related Party Revenue Our revenue to date has been generated primarily from recognition of license fees and R&D service funding pursuant to our collaboration with Merck. Merck is also a significant stockholder and, as such, collaboration revenue from Merck is referred to as related party revenue. Since inception throughJune 30, 2021 , Merck had paid us$541.6 million under the collaboration. Due to the nature of our collaboration with Merck and the timing of related revenue recognition, our revenue has fluctuated 31 -------------------------------------------------------------------------------- from period to period in the past and we expect that it will continue to fluctuate in future periods, particularly given the amendment and restatement of the collaboration onJune 30, 2021 . As a result, we believe that period-to-period comparisons of our revenue may not be meaningful and should not be relied upon as being indicative of future performance. We use the cost-based input method in accordance with Accounting Standards Codification 606, or ASC 606, to calculate the corresponding amount of revenue to recognize at each reporting period. In applying the cost-based input measure of revenue recognition, we measure actual costs incurred relative to budgeted costs to fulfill our performance obligation. We apply considerable judgment when we re-evaluate the estimate of expected costs to satisfy the performance obligation each reporting period and make adjustments for any significant changes. A significant change in the estimate of expected costs under the Amended Collaboration Agreement could have a material impact on revenue recognized (including the possible reversal of previously recognized revenue) at each reporting period. Our related party revenue was as follows (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 Related party revenue$ 16,773 $ 19,755 $ 38,348 $ 44,119 Research and Development Expenses R&D efforts include drug discovery research activities and development activities relating to our product candidates, such as manufacturing drug substance, drug product and other clinical trial materials, conducting preclinical studies and clinical trials and providing support for these operations. Our R&D expenses consist of both internal and external costs. Our internal costs include employee, consultant, facility and other R&D operating expenses. Our external costs include fees paid to CROs and other service providers in connection with our clinical trials and preclinical studies, third-party license fees and CMO costs related to manufacturing drug substance, drug product and other clinical trial materials. Our R&D expenses related to the development of aldafermin, MK-3655, NGM621, NGM120, NGM707 and NGM438 (and prior to suspending these programs, NGM386, NGM395 and NGM217) consist primarily of: •fees paid to our CROs in connection with our clinical trials and other related clinical trial fees, when applicable; •costs related to acquiring and manufacturing drug substance, drug product and clinical trial materials, including continued testing, such as process validation and stability, of drug substance and drug product; •costs related to toxicology testing and other research and preclinical related studies; •salaries and related overhead expenses, which include stock-based compensation and benefits, for personnel in R&D functions; •fees paid to consultants for R&D activities; •R&D operating expenses, including facility costs and depreciation expenses; and •costs related to compliance with regulatory requirements. Our clinical development efforts are spread across multiple programs, only some of which remain within the scope of our collaboration with Merck. For the foreseeable future, we anticipate the majority of our financial resources, other than those received from Merck and dedicated to continuing collaboration activities under the Amended Collaboration Agreement, will be directed to activities required to advance our Phase 2b ALPINE 4 clinical trial of aldafermin and our trials of NGM120 and NGM707 and to initiate a clinical trial of NGM438. Our R&D efforts are extensive and costly. While Merck has committed under the Amended Collaboration Agreement to provide up to$86.0 million in research funding for the four calendar quarters endingMarch 31, 2022 (with up to$51.0 million of such amount that may be used by us to advance certain of our wholly owned programs), afterMarch 2022 and through the remaining two years of the research phase of the collaboration, Merck is committed to provide only up to$20.0 million in research funding for the ophthalmology- and CVM-related programs (other than NGM621) and to fund certain R&D costs related to NGM621, expected to be approximately$15.0 million , during the earlier of the remaining two years of the research phase afterMarch 2022 or until Merck exercises, or decides not to exercise, its Merck license option with respect to NGM621. As a result, afterMarch 2022 , we will need to devote a substantial amount of our own financial resources to our development programs, 32 -------------------------------------------------------------------------------- particularly with respect to our wholly owned programs and, to a lesser extent, with respect to our programs that are within the scope of the Amended Collaboration Agreement that we are required to fund. In addition, our funding requirements would increase for any programs that are within the scope of the continuing collaboration in the event Merck does not elect to license these programs, in the event Merck elects to terminate its license to any program it licenses or in the event we opt to co-develop any Merck-licensed programs. Accordingly, we will require significant additional capital in order to proceed with the development through to regulatory approval and commercialization of our current and potential future product candidates or we will need to enter into additional collaboration or license agreements in order to fund such development and commercialization. Neither may be possible and, as a result, we may be required to delay, scale back or discontinue development of such product candidates, which could have a material adverse effect on our business, operating results and prospects. In addition, our R&D expenses may exceed the funding caps set forth under the Amended Collaboration Agreement, as happened in the fiscal year endedDecember 31, 2020 under the Original Agreement, and is expected to occur in the fiscal year endingDecember 31, 2021 , in which case our funding requirements will increase. The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs of the efforts that will be necessary to complete the remainder of the development of our product candidates. This is due to the numerous risks and uncertainties associated with developing medicines, including the uncertainty of: •our ability to hire and retain key R&D personnel; •manufacturing scale-up challenges, production shortages or other supply disruptions for clinical trial materials; •the evolving effects of the COVID-19 pandemic on our employees, patients, clinical trial sites and our CROs, CMOs and other service providers; •the timely and quality performance of our CROs, CMOs and other service providers; •whether Merck will elect to license, or to terminate its license, to any of our programs within the scope of the continuing collaboration and the timing of such election or termination; •prior toMarch 2022 , the extent to which we exceed the funding caps provided in the Amended Collaboration Agreement; •afterMarch 2022 , the amount of our financial resources that we will need to devote to our development programs and our obligations under the Amended Collaboration Agreement, and our ability to raise adequate additional capital to meet our requirements; •the effect of products that may compete with our product candidates or other market developments; •our ability to expand and enforce our intellectual property portfolio; •the scope, rate of progress, results and expense of our ongoing, as well as any future, clinical trials and other R&D-related activities; and •the impact and timing of any interactions with regulatory authorities. A change in the outcome of any of the risks and uncertainties associated with the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another health authority were to require us to conduct clinical trials beyond those that we currently anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development. For additional discussion of the risks and uncertainties associated with our R&D efforts, see "Risk Factors-Risks Related to Our Business and Industry," "-Risks Related to Our Dependence on Merck and Other Third Parties" and "-Risks Related to Regulatory Approvals" in Part II, Item 1A of this Quarterly Report on Form 10-Q. General and Administrative Expenses General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation and benefits. Other significant costs include legal fees relating to patent and corporate matters, facility costs not otherwise included in R&D expenses and fees for accounting and other consulting services. We anticipate that our general and administrative expenses will increase in the future to support our continued R&D activities. These increases will likely include increased costs related to the hiring of additional personnel, as well as fees paid to outside consultants, lawyers and accountants, among other expenses. Additionally, we anticipate continued increased costs associated with being a public company, including expenses 33 -------------------------------------------------------------------------------- related to services associated with maintaining compliance with Nasdaq listing rules and relatedSecurities and Exchange Commission , orSEC , requirements and costs related to insurance, investor relations and SOX 404 compliance. In addition, we may incur expenses associated with building a commercial organization in connection with, and prior to, potential future regulatory approval of our product candidates. Results of Operations

As ofMarch 31, 2021 , the Company had a contract asset of$4.6 million under the prior two-year extension of the research phase which, under the Amended Collaboration Agreement, was no longer billable to Merck at any point and therefore was recorded as a reduction in revenue onJune 30, 2021 . Research and Development Expenses Our R&D expenses by program were as follows (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 External R&D expenses: Aldafermin (FGF19 analog)$ 9,474 $ 11,286 $ 19,072 $ 25,437 NGM621 (C3 inhibitor) 5,491 2,597 9,177 3,895 NGM120 (GFRAL antagonist) 2,235 1,529 3,596 2,894 NGM707 (Anti-ILT2/ILT4 dual antagonist) 1,056 1,843 2,221 2,603 NGM438 (LAIR1 antagonist) 956 345 2,471 387 MK-3655 (FGFR1c/KLB agonist) 574 403 609 532 NGM395 (GDF15 analog) 302 1,131 537 1,607 Other external R&D expenses 688 1,975 1,396 3,910 Total external R&D expenses 20,776 21,109 39,079 41,265 Personnel-related expenses 14,192 10,775 28,461 21,593 Internal and unallocated R&D expenses(1) 8,602 6,610 16,729 14,075 Total R&D expenses$ 43,570 $ 38,494 $ 84,269 $ 76,933 _____________
(1)Internal and unallocated research and development expenses consist primarily of research supplies and consulting fees, which we deploy across multiple research and development programs.
34 -------------------------------------------------------------------------------- R&D expenses increased$5.1 million and$7.3 million in the three and six months endedJune 30, 2021 compared to the same periods in 2020, respectively, primarily due to increases in external expenses driven by our ongoing clinical trials of NGM621 and NGM120 and our preclinical studies of NGM438, and increases in personnel-related and internal and unallocated R&D expenses. These increases were partially offset by decreases in expenses for our manufacturing activities and our clinical trials of aldafermin and in external expenses related to our other development programs. We expect R&D expenses for the remainder of 2021 to increase compared to 2020 due to our ongoing activities, particularly as we advance our clinical development of NGM621 and our oncology programs. We are continuing to advance Phase 2b development of aldafermin for the treatment of patients with compensated NASH cirrhosis (F4 liver fibrosis). Resources previously intended for a Phase 3 F2/F3 NASH development program have been shifted toward advancing our other programs. In addition, we may be required to develop and implement additional clinical study policies and procedures to mitigate the evolving effects of the COVID-19 pandemic, which could significantly increase our R&D expenses. General and Administrative Expenses General and administrative expenses increased$3.0 million and$5.2 million in the three and six months endedJune 30, 2021 compared to the same periods in 2020, respectively, primarily due to an increase in personnel-related expenses due to increased headcount and an increase in stock-based compensation expense primarily due to an increase in the average grant date fair value of stock options granted in the six months endedJune 30, 2021 . We anticipate general and administrative expenses for the remainder of 2021 to increase compared to 2020 due to an increase in compensation-related expenses driven by higher headcount and other expenses related to the expansion and support of our business including expenses related to SOX 404 compliance. Interest Income Interest income decreased in the three and six months endedJune 30, 2021 compared to the same periods in 2020 primarily due to the decrease in market interest rates. Liquidity and Capital Resources Funding Requirements We have incurred net losses every year since inception. We have spent, and expect to continue to spend, significant resources to fund R&D of, and seek regulatory approvals for, our product candidates. These activities require us to incur substantial costs related to research, development, manufacturing, preclinical studies, clinical trial and related activities, as well as to cover other expenses related to our ongoing operations. Our collaboration with Merck under the Original Agreement has provided us with substantial financial support; however, under the narrower scope of the Amended Collaboration Agreement, afterMarch 2022 the level of research funding from Merck will be substantially lower on an annual and overall basis than the research funding provided by Merck prior to that date, as described below. In this regard, afterMarch 2022 , we will need to devote a substantial amount of our own financial resources to our development programs, particularly with respect to our wholly owned programs and, to a lesser extent, with respect to our programs that are within the scope of the continuing collaboration under the Amended Collaboration Agreement that we are required to fund, and our failure to allocate funding to meet such requirements may be deemed a breach of the Amended Collaboration Agreement. In addition, our funding requirements would increase for any programs that are within the scope of the continuing collaboration in the event Merck does not elect to license these programs, in the event Merck elects to terminate its license to any program it licenses or in the event we opt to co-develop any Merck-licensed programs. Accordingly, we will require significant additional capital in order to proceed with the development through to regulatory approval and commercialization of our current and potential future product candidates or we will need to enter into additional collaboration or license agreements in order to fund such development and commercialization. Neither may be possible and, as a result, we may be required to delay, scale back or discontinue development of such product candidates, which could have a material adverse effect on our business, operating results and prospects. In addition, our R&D expenses may exceed the funding caps set forth under the Amended Collaboration Agreement, as happened in the fiscal year endedDecember 31, 2020 under the Original Agreement, and is expected to occur in the fiscal year endingDecember 31, 2021 , in which case, our funding requirements will increase. See "Overview of Our Business - Merck Collaboration Update" above. As a result, we expect to incur significant and increasing operating losses. We have no products approved for commercial sale, have not generated any revenue from product sales to date and we are not and may never be profitable. We have incurred losses in each year since commencing operations. As of 35 --------------------------------------------------------------------------------June 30, 2021 , we had an accumulated deficit of$362.9 million and we expect our accumulated deficit will increase significantly over time. The size of our future net losses will depend, in part, on the rate of future growth of our expenses, the amount of revenue generated from Merck under the Amended Collaboration Agreement and our ability to generate revenue outside of the Merck collaboration, particularly afterMarch 2022 . Sources of Liquidity Merck Collaboration The revenue we receive under the Amended Collaboration Agreement with Merck is our only source of revenue. As described in greater detail above, including under "Overview of Our Business - Merck Collaboration Update," under the Amended Collaboration Agreement, Merck has committed to provide us with up to$86.0 million in research funding for the four calendar quarters endingMarch 31, 2022 (with up to$51.0 million of such amount that may be used by us to advance certain of our wholly owned programs). However, afterMarch 2022 and through the remaining two years of the research phase of the collaboration, Merck is committed to provide only up to$20.0 million in research funding for the ophthalmology- and CVM-related programs and to fund the R&D costs related to NGM621, including our CATALINA clinical trial, subject to certain limitations. Other Sources of Liquidity InJune 2020 , we entered into the Sales Agreement with Jefferies relating to the sale of shares of our common stock. In accordance with the terms of the Sales Agreement, we may offer and sell shares of our common stock having an aggregate offering price of up to$150.0 million from time to time through Jefferies, acting as our sales agent. During the six months endedJune 30, 2021 , no shares of our common stock were sold pursuant to the Sales Agreement. As ofJune 30, 2021 ,$127.4 million of our common stock remained available to be sold under the Sales Agreement, subject to conditions specified in the Sales Agreement. InJanuary 2021 , we sold 5,324,074 shares of common stock (inclusive of shares sold pursuant to the full exercise of the option to purchase additional shares granted to the underwriters in connection with the offering) through an underwritten public offering at a price to the public of$27.00 per share for aggregate net proceeds to the Company of$134.6 million , or the follow-on offering. As ofJune 30, 2021 , we had cash and cash equivalents of$99.4 million , short-term marketable securities of$291.1 million , working capital of$358.1 million and an accumulated deficit of$362.9 million . We believe that our existing cash, cash equivalents and short-term marketable securities will be sufficient to fund our operations for at least the next twelve months from the date our interim condensed financial statements are filed. We have based this estimate on assumptions that may prove to be wrong and we could utilize our available capital resources sooner than we currently expect. In addition, our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially as a result of a number of factors, including the factors discussed under "Risk Factors" in Part II, Item 1A of this Quarterly Report on Form 10-Q. We plan to finance our future cash needs through public or private equity or debt offerings, including under the Sales Agreement, government or other third-party funding, product collaborations, strategic alliances, licensing arrangements or a combination of these. Additional capital may not be available in sufficient amounts, on reasonable terms or when we need it, if at all, and our ability to raise additional capital may be adversely impacted by worsening global economic conditions and the disruptions to, and volatility in, the credit and financial markets inthe United States and worldwide resulting from, among other things, the evolving effects of the COVID-19 pandemic. If we raise additional funds by issuing equity securities, our stockholders may experience dilution. Debt financing, if available, may involve restrictive covenants. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. Furthermore, any securities that we may issue may have rights senior to those of our common stock and could contain covenants or protective rights that would lead to restrictions on our operations and potentially impair our competitiveness, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we are unable to raise adequate additional capital, we may be prevented from pursuing development and commercialization efforts, which will have a material adverse effect on our business, operating results and prospects. 36 -------------------------------------------------------------------------------- Cash Flow Activity The following table summarizes our cash flow activity for the periods indicated (in thousands): Six Months Ended June 30, 2021 2020 Net cash provided by (used in): Operating activities (45,535) (38,291) Investing activities (145,880) 34,992 Financing activities 143,801 7,018
Net (decrease) increase in cash and cash equivalents
Operating Activities In the six months endedJune 30, 2021 net cash used in operating activities was$45.5 million , which consisted of a net loss of$64.2 million , adjusted for non-cash charges of$22.6 million and a change in operating assets and liabilities of$3.9 million . The non-cash charges consisted primarily of stock-based compensation expense of$13.3 million , a decrease in related party contract assets due to the Amended Collaboration Agreement with Merck of$4.6 million and depreciation expense of$3.1 million . The change in operating assets and liabilities was mainly driven by increases in contract liabilities of$5.0 million , increases in prepaid expenses and other current assets of$3.2 million and the related party receivable of$3.3 million , partially offset by decreases in related party contract assets of$1.5 million and accounts payable of$4.5 million . In the six months endedJune 30, 2020 cash used in operating activities was$38.3 million , which consisted of a net loss of$44.7 million , adjusted for non-cash charges of$10.8 million and cash used through changes in operating assets and liabilities of$4.4 million . The non-cash charges consisted primarily of stock-based compensation expense of$7.4 million and depreciation expense of$3.4 million . The change in operating assets and liabilities was mainly driven by an increase in prepaid expenses and other assets of$3.1 million and an increase in accrued expenses of$7.6 million . These increases were partially offset by a decrease in related party receivable from our Merck collaboration of$2.1 million , a decrease in accounts payable of$6.9 million , a decrease in deferred rent of$1.4 million and a decrease in deferred revenue of$2.7 million primarily attributable to the timing of advance payments from Merck related to the reimbursement of costs associated with R&D activities. Investing Activities In the six months endedJune 30, 2021 cash used in investing activities was$145.9 million , which consisted of purchases of marketable securities of$194.5 million primarily from the net proceeds of the follow-on offering, partially offset by$50.0 million in net proceeds on maturity of marketable securities. In the six months endedJune 30, 2020 cash provided by investing activities was$35.0 million , which consisted of$65.8 million in net proceeds on maturity of marketable securities, partially offset by purchases of marketable securities of$29.4 million and purchases of property and equipment of$1.4 million . Financing Activities In the six months endedJune 30, 2021 cash provided by financing activities was$143.8 million , which consisted of net proceeds from the follow-on offering of$134.6 million and proceeds from employee equity incentive plans of$7.8 million . In the six months endedJune 30, 2020 cash provided by financing activities was$7.0 million , which primarily consisted of proceeds from employee equity incentive plans. Off-Balance Sheet Arrangements We currently have not entered into and do not have any relationships with unconsolidated entities or financial collaborations, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purpose. 37 -------------------------------------------------------------------------------- Contractual Obligations During the six months endedJune 30, 2021 , there were no material changes to our contractual obligations as set forth in Part II, Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year endedDecember 31, 2020 . Critical Accounting Policies and Estimates Our management's discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which we have prepared in accordance withU.S. generally accepted accounting principles. The preparation of our condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of our condensed consolidated financial statements, as well as revenue and expenses during the reported periods. We evaluate these estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions. We believe that there have been no significant changes in our critical accounting policies and estimates disclosed in our Annual Report on Form 10-K for the year endedDecember 31, 2020 . Newly Issued Accounting Pronouncements Except as described in Note 2 to the condensed consolidated financial statements under the headings "Recently Adopted Accounting Pronouncements" and "Recent Accounting Pronouncements Not Yet Adopted," there have been no new accounting pronouncements or changes to accounting pronouncements during the six months endedJune 30, 2021 , as compared to the recent accounting pronouncements described in our audited consolidated financial statements and notes for the year endedDecember 31, 2020 , included in the Company's Annual Report on Form 10-K for the year endedDecember 31, 2020 , that are of significance or potential significance to us. Item 3. Quantitative and Qualitative Disclosures About Market Risk. During the six months endedJune 30, 2021 , there were no material changes to our market risk disclosures as set forth in Part II, Item 7A "Quantitative and Qualitative Disclosures About Market Risk" in our Annual Report on Form 10-K for the year endedDecember 31, 2020 . Item 4. Controls and Procedures. Evaluation of Disclosure Controls and Procedures As ofJune 30, 2021 , management, with the participation of our Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in theSEC's rules and forms, and that such information is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objective and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as ofJune 30, 2021 , the design and operation of our disclosure controls and procedures were effective at a reasonable assurance level. Changes in Internal Control over Financial Reporting During the quarter endedJune 30, 2021 , there have been no changes to our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 38
