                            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 liver and metabolic diseases, retinal diseases and cancer. 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. Pipeline Programs and Operations Updates

Our discovery engine supports our ability to advance multiple product candidates across our three key therapeutic areas. We currently have five ongoing Phase 2 and Phase 2b programs. In 2021 to date, we have continued to progress the development of our leading product candidates as described below:



•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 and is in Phase 2b
development for the treatment of patients with non-alcoholic steatohepatitis, or
NASH, with liver fibrosis stage 2, 3 or 4, or F2, F3 or F4. To date in 2021, we:
?completed treatment of patients in our Phase 2b ALPINE 2/3 clinical trial of
aldafermin in patients with NASH with F2 and F3 liver fibrosis and
?continued enrollment in our Phase 2b ALPINE 4 clinical trial of aldafermin in
patients with NASH with F4 liver fibrosis and compensated cirrhosis, with a goal
of enrolling approximately 160 patients across 70 sites in the United States,
Europe, Hong Kong and Australia.
?Looking forward: We expect to report topline results from the ALPINE 2/3 trial
in the second quarter of 2021. We are leveraging the results of our completed
clinical trials of aldafermin, as well as guidance from the U.S. Food and Drug
Administration, or FDA, to support our design of a pivotal clinical trial
program to enable a potential biologics license application, or BLA, submission.
                                       23

--------------------------------------------------------------------------------



•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 is in
Phase 2b development for the treatment of NASH and was optioned by Merck Sharp &
Dohme Corp., or Merck, under our collaboration with Merck described below. To
date in 2021, Merck:
?continued the worldwide 52-week randomized, double-blind Phase 2b trial of
MK-3655 in patients with NASH with F2 or F3 liver fibrosis that it initiated in
the fourth quarter of 2020.
•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. Merck
has a one-time option to license NGM621 upon completion of a proof-of-concept
study in humans. To date in 2021, we:
?continued enrollment in the Phase 2 CATALINA clinical trial of NGM621 in
patients with GA to evaluate NGM621's effects on disease progression when given
every four weeks or every eight weeks. The CATALINA trial was designed to be a
Phase 3-supportive or -enabling clinical trial.
?Looking forward: Subject to any future impact of the COVID-19 pandemic on
enrollment, we expect to complete enrollment in the CATALINA trial in mid-2021.
•Oncology.
•NGM120. NGM120 is an antagonistic 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 clinical trials
to assess NGM120's effect on cancer-related cachexia and on cancer in patients
with select advanced solid tumors and metastatic pancreatic cancer. Merck has a
one-time option to license NGM120 upon completion of a proof-of-concept study in
humans. To date in 2021, we:
?initiated a Phase 2 placebo-controlled component of the ongoing Phase 1/2
clinical trial of NGM120 described below. This 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 second half 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 monoclonal antibody that inhibits
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 T-cell checkpoint
resistance. Merck has a one-time option to license NGM707 upon completion of a
proof-of-concept study in humans.
?Looking forward: We expect to commence a first-in-human Phase 1 clinical trial
of NGM707 in patients with advanced solid tumors in mid-2021.
•NGM438. NGM438 is an antagonistic antibody that is designed to inhibit
leukocyte-associated immunoglobulin-like receptor 1, or LAIR1, and promote
immune detection and activation against advanced solid tumors. Merck has a
one-time option to license NGM438 upon completion of a proof-of-concept study in
humans. In 2021, we:
?advanced the preparation of an investigational new drug, or IND, application
for a planned submission in the second half of 2021.
                                       24

--------------------------------------------------------------------------------



?Looking forward: We expect to commence a first-in-human Phase 1 clinical trial
of NGM438 in patients with advanced solid tumors in the fourth quarter of 2021.
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, 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 key component of our
strategy as we plan to continue to develop a broad portfolio of product
candidates and, if approved, to commercialize the resulting products. Our
existing research collaboration, product development and license agreement with
Merck, or the Collaboration Agreement, which we entered into in 2015, has to
date provided us with substantial financial support from Merck. The
collaboration has also afforded us substantial freedom to pursue development
efforts for our collaboration programs and product candidates. We are currently
in discussions with Merck with respect to modifying certain terms of the
collaboration, as described in more detail below. In addition, for any programs
wholly-owned by us and not subject to the Merck collaboration, such as
aldafermin, we may decide to pursue a strategic partner to progress, in whole or
in part, the program or commercialize any resulting approved product.
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 activities required
to prepare aldafermin for potential regulatory approval for the treatment of
NASH, including manufacturing of clinical trial materials and preparation for
potential Phase 3 testing. If our CROs 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 aldafermin trials would 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 the suspension of development activities on multiple
viable product candidates for portfolio management reasons in order to
concentrate our resources on what we consider our most promising product
candidates. For example, in 2020, we suspended development activities related to
multiple metabolic disease product candidates in order to concentrate our
resources on aldafermin and certain other product candidates subject to our
Merck collaboration.
Status of Merck Collaboration
The original research phase of our existing research collaboration, product
development and license agreement with Merck, or the Collaboration Agreement,
was for five years. In March 2019, Merck exercised its option to extend the
research phase of the collaboration through March 16, 2022. Under the terms of
the collaboration, Merck was required to notify us no later than March 17, 2021
of its unilateral decision whether to exercise its option to extend the research
phase of the collaboration for an additional two-year term through March 16,
2024. In March 2021, Merck initiated discussions with us with respect to
elements of the ongoing collaboration that might be optimized to better address
the evolving interests and priorities of both NGM and Merck during the remainder
of the current research phase through March 16, 2022 and during any extension of
the current research phase and any tail period after the end of the research
phase. In this regard, the parties continue to negotiate potential modifications
to the terms of the collaboration. Such modifications may include, among other
things, focusing NGM's research and development under the collaboration on
therapeutic areas of particular interest to Merck, while enabling NGM to conduct
research and development outside of these therapeutic areas, which would, if
mutually agreed to, allow NGM to discover and develop product candidates on its
own or with third parties in other areas of interest. In order to allow
negotiations to proceed, the parties agreed to extend the March 17, 2021
deadline for Merck to deliver its extension notification decision until June 30,
2021. While we do not know whether or when Merck will elect to extend the
research phase of the collaboration or on what terms, or whether or when we will
reach agreement with Merck on the terms of a modified collaboration, we expect
that any modified collaboration would result in a level of annual research
support from Merck during any extension of the current research phase
                                       25

--------------------------------------------------------------------------------



after March 16, 2022 that is meaningfully lower than the annual research support
Merck provided during the initial five-year term and is providing during the
current two-year extension of the research phase. In this regard, we expect that
under the terms of a modified collaboration, Merck will not provide research
funding for certain of our product candidates. We also expect that if we are
unable to reach agreement with Merck on modified terms, Merck will not elect to
extend the research phase of the collaboration and will decide not to proceed
with certain of our product candidates after the end of the research phase. In
any event, we expect that following March 16, 2022, the end of the current
two-year extension of the research phase, funding from Merck will substantially
decrease and our funding for the development of our current and potential future
product candidates will substantially increase regardless of whether we are able
to reach agreement with Merck on modified terms.
Financial Highlights
Since inception, we have funded our operations primarily through:
•fees received from collaboration partners, which since inception through
March 31, 2021 includes reimbursement of research and development expenses of
$423.7 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 in December 2020 under an Open Market
Sale AgreementSM, or the Sales Agreement, we entered into with Jefferies LLC, or
Jefferies, in June 2020; and
•net proceeds of $134.6 million from the sale of 5,324,074 shares of our common
stock in January 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.
At March 31, 2021, we had $412.7 million in cash, cash equivalents and
short-term marketable securities.
We have incurred net losses each year since our inception. As of March 31, 2021,
we had an accumulated deficit of $326.2 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
collaboration partners, including Merck. 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 substantially remote work model. Employees working on site continue to be
primarily those individuals conducting essential in-person laboratory work and
other business functions considered essential under COVID-19 regulations and
guidance, and we are still encouraging all other individuals to work remotely
where feasible. 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 early 2021, we 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, return to a
fully office-based working model or whether we will be required to adopt a more
restrictive work model as the implications of the pandemic evolve.
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
                                       26

--------------------------------------------------------------------------------



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. Most of our clinical
trial sites, both within and outside of the 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 and we believe the
higher-than-planned enrollment we achieved in our ALPINE 2/3 trial has mitigated
the effects of the increased dropout rate, as the pandemic continues, there may
be continuing 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, institutional review boards 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 any 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 continuing pandemic,
and associated delays in the manufacturing and supply of drug substance and drug
product for our clinical trials, which could adversely affect our ability to
conduct ongoing and future clinical trials of our product candidates. For
example, our aldafermin drug product CMO has advised us that it could be
required under orders of the U.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 of U.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, particularly our ongoing and
planned aldafermin trials, 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 Collaboration Agreement, to exercise its remaining option to extend
the research phase of the collaboration beyond March 16, 2022 or to reach
agreement with us on the terms of a modified collaboration, if any. 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 Agreement with Merck.
Merck is also a significant stockholder and, as such, collaboration revenue from
Merck is referred to as related party revenue.
Merck Collaboration
In 2015, we entered into the Collaboration Agreement with Merck, covering the
discovery, development and commercialization of novel therapies across a range
of therapeutic areas, including a broad, multi-year drug discovery and early
development program financially supported by Merck, but scientifically directed
by us with input from Merck. Merck generally has a one-time right to exercise
its option to an exclusive, worldwide license for any collaboration product
candidate and related program when a human proof-of-concept trial is completed.
In 2018, Merck exercised its option to license MK-3655, which is a potential
treatment for NASH. Under the current terms of the Collaboration Agreement, for
a program that Merck licenses, we retain an option, when a product candidate has
advanced to Phase 3 clinical trials, to participate in up to 50% of the economic
return from that product candidate if
                                       27

--------------------------------------------------------------------------------



it becomes an approved medicine by agreeing to share up to 50% of the costs of
future development. If we do not elect this option, we will instead receive
milestone and royalty payments and we will not be required to share in
development costs.
The aldafermin program is not included in the Collaboration Agreement and it
remains wholly-owned and controlled by us.
For a more detailed description of the current terms of the Collaboration
Agreement and the status of the collaboration, see "Our Collaboration with
Merck" in Part I, Item 1A of our Annual Report on Form 10-K for the year ended
December 31, 2020 and "Overview of Our Business - Status of Merck Collaboration"
above. Since inception through March 31, 2021, Merck had paid us $518.5 million
under the Collaboration Agreement. Due to the nature of our agreement with Merck
and the timing of related revenue recognition, our revenue has fluctuated from
period to period in the past and we expect that it will continue to fluctuate in
future periods.
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 for the
remainder of the current two-year extension period 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
                                March 31,

Related party revenue   $   21,575      $ 24,364


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, most of
which are subject to the Merck collaboration. For the foreseeable future, we
anticipate the majority of our financial resources, other than those received
from Merck and dedicated to Merck collaboration activities, will be dedicated to
activities required to prepare aldafermin for potential regulatory approval for
the treatment of NASH, including manufacturing of clinical trial materials and
preparation for a potential pivotal program.
                                       28

--------------------------------------------------------------------------------



In the future, we may devote financial resources to other programs in the event
Merck does not elect to license these programs upon completion of a
proof-of-concept study, 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, or if Merck no longer funds such programs under modified terms of the
collaboration.
Our R&D efforts under the Merck collaboration are extensive and costly and are
currently subject to reimbursement under our Merck collaboration during the
current two-year extension up to the funding caps provided in our Collaboration
Agreement. If our R&D expenses for product candidates subject to the Merck
collaboration, including the clinical development of product candidates subject
to the Merck collaboration through completion of proof-of-concept studies,
exceed the funding caps provided in the Collaboration Agreement, which happened
in the fiscal year ended December 31, 2020 and could happen in the future, we
will be required to devote our own financial resources toward the development of
such product candidates or, if we are unwilling or unable to do so, pause or
suspend such development to remain within the funding caps. In addition, while
we do not know whether or when Merck will elect to extend the research phase of
the collaboration through March 16, 2024 or on what terms, or whether or when we
will reach agreement with Merck on the terms of a modified collaboration, we
expect that any modified collaboration would result in a level of annual
research support from Merck during any extension of the current research phase
after March 16, 2022 that is meaningfully lower than the annual research support
Merck provided during the initial five-year term and is providing during the
current two-year extension of the research phase. In this regard, we expect that
under the terms of a modified collaboration, Merck will not provide research
funding for certain of our product candidates. We also expect that if we are
unable to reach agreement with Merck on modified terms, Merck will not elect to
extend the research phase of the collaboration and will decide not to proceed
with certain of our product candidates after the end of the current research
phase. In any event, we expect that following March 16, 2022, the end of the
current two-year extension of the research phase, funding from Merck will
substantially decrease and our funding for the development of our current and
potential future product candidates will substantially increase, regardless of
whether we are able to reach agreement with Merck on modified terms.
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 and the timing of such election or termination;
•whether we exceed the current or any future funding caps provided in our
Collaboration Agreement and whether Merck decides not to proceed with certain of
our product candidates after the end of the research phase;
•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

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 related to services associated with
maintaining compliance with Nasdaq listing rules and related Securities and
Exchange Commission, or SEC, 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.

Related Party Revenue from Merck Revenue decreased $2.8 million in the three months ended March 31, 2021 compared to the same period in 2020 primarily due to a decrease in the recognition of a portion of the initial upfront payment received from Merck in 2015 that was included within the transaction price and fully recognized over the initial five-year term of our Collaboration Agreement using the cost-based input model. The initial five-year term ended in the first quarter of 2020.

$   40,699      $ 38,439


(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.
R&D expenses increased $2.3 million in the three months ended March 31, 2021
compared to the same period in 2020 primarily due to a $3.5 million increase in
personnel-related expenses and an increase in external expenses driven by our
ongoing clinical and preclinical studies of NGM621, NGM438 and NGM707. These
increases were partially offset by decreases of $4.6 million in expenses for our
manufacturing activities and our ongoing clinical trials of aldafermin and
$1.2 million 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 aldafermin. 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 $2.1 million in the three months
ended March 31, 2021 compared to the same period in 2020 primarily due to an
increase in personnel-related expenses due to increased headcount and an
increase in stock-based compensation expense primarily related to the increase
in our stock price.
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 $1.1 million in the three months ended March 31, 2021 compared to the same period 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 our 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, particularly aldafermin. These activities require us to incur substantial costs related to research, development, manufacturing,


                                       31

--------------------------------------------------------------------------------



preclinical studies, clinical trial and related activities, as well as to cover
other expenses related to our ongoing operations. For example, we will require
substantial additional capital to achieve our development and commercialization
goals for our aldafermin program that is being conducted outside of the Merck
collaboration or for any other programs in the event Merck does not elect to
license these programs upon completion of a proof-of-concept study, 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, or if Merck no longer funds
such programs under modified terms of the collaboration. In addition, while we
do not know whether or when Merck will elect to extend the research phase of the
collaboration through March 16, 2024 or on what terms, or whether or when we
will reach agreement with Merck on the terms of a modified collaboration, we
expect that any modified collaboration would result in a level of annual
research support from Merck during any extension of the current research phase
after March 16, 2022 that is meaningfully lower than the annual research support
Merck provided during the initial five-year term and is providing during the
current two-year extension of the research phase. See "Overview of Our Business
- Status of Merck Collaboration" 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 March 31, 2021, we had an accumulated deficit
of $326.2 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, how much revenue, if any,
continues to be generated under the Merck collaboration and our ability to
generate revenue outside of the Merck collaboration.
In addition, if our R&D expenses for product candidates subject to the Merck
collaboration exceed the funding caps provided in our current Collaboration
Agreement, which happened in the fiscal year ended December 31, 2020 and could
happen in the future, or if Merck no longer funds such programs under modified
terms of the collaboration, we will be required to devote our own financial
resources toward the development of such product candidates or, if we are
unwilling or unable to do so, pause or suspend such development to remain within
the funding caps or to proceed with development of unfunded programs.
Sources of Liquidity
Merck Collaboration
The revenue we receive under our Collaboration Agreement with Merck is our only
source of revenue. The original research phase of the Collaboration Agreement
was for five years. As described in greater detail in "Overview of Our Business
- Status of Merck Collaboration" above, the parties continue to negotiate
potential modifications to the terms of the collaboration. While we do not know
whether or when Merck will elect to extend the research phase of the
collaboration or on what terms, or whether or when we will reach agreement with
Merck on the terms of a modified collaboration, we expect that any modified
collaboration would result in a level of annual research support from Merck
during any extension of the current research phase after March 16, 2022 that is
meaningfully lower than the annual research support Merck provided during the
initial five-year term and is providing during the current two-year extension of
the research phase. In this regard, we expect that under the terms of a modified
collaboration, Merck will not provide research funding for certain of our
product candidates. We also expect that if we are unable to reach agreement with
Merck on modified terms, Merck will not elect to extend the research phase of
the collaboration and will decide not to proceed with certain of our product
candidates after the end of the research phase. In any event, we expect that
following March 16, 2022, the end of the current two-year extension of the
research phase, funding from Merck will substantially decrease and our funding
with respect to the development of our current and potential future product
candidates will substantially increase, regardless of whether we are able to
reach agreement with Merck on modified terms. Accordingly, we will require
significant additional capital in order to proceed with development and
commercialization of our current and potential future product candidates,
including any product candidate that had been subject to the Merck collaboration
but Merck decides not to proceed with under the terms of a modified
collaboration or after the end of the research phase, 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.
Other Sources of Liquidity
In June 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. As of March 31, 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.
                                       32

--------------------------------------------------------------------------------



In January 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 of March 31, 2021, we had cash and cash equivalents of $148.1 million,
short-term marketable securities of $264.5 million, working capital of $385.5
million and an accumulated deficit of $326.2 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. 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 in the 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.

Financing activities                            140,477         3,591

Net increase in cash and cash equivalents $ 1,096 $ 11,354

Cash Used in Operating Activities During the three months ended March 31, 2021, cash used in operating activities was $22.2 million, which consisted of a net loss of $27.5 million, adjusted for non-cash charges of $8.4 million and net cash used in operating assets and liabilities of $3.1 million. The non-cash charges consisted primarily of stock-based compensation expense of $6.6 million and depreciation expense of $1.6 million. The change in operating assets and liabilities was mainly driven by decreases in accounts payable of $2.1 million, related party contract assets of $1.5 million and deferred rent of $0.7 million, partially offset by an increase in prepaid expenses and other current assets of $1.3 million. During the three months ended March 31, 2020, cash used in operating activities was $19.1 million, which consisted of a net loss of $19.1 million, adjusted for non-cash charges of $5.4 million and cash used through changes in operating assets and liabilities of $5.4 million. The non-cash charges consisted primarily of stock-based compensation expense of $3.7 million and depreciation expense of $1.7 million. The change in operating assets and liabilities was mainly driven by an increase in prepaid expenses and other assets of $2.0 million and an


                                       33

--------------------------------------------------------------------------------



increase in accrued expenses of $3.0 million. These increases were partially
offset by a decrease in related party receivable from our Merck collaboration of
$4.5 million, a decrease in accounts payable of $5.3 million, a decrease in
deferred rent of $0.7 million and a decrease in deferred revenue of $4.9 million
primarily attributable to the timing of advance payments from Merck related to
the reimbursement of costs associated with R&D activities.
Cash Provided by (Used in) Investing Activities
During the three months ended March 31, 2021, cash used in investing activities
was $117.2 million, which consisted of purchases of marketable securities of
$145.0 million with net proceeds from our follow-on offering, partially offset
by $28.0 million in net proceeds on maturity of marketable securities. During
the three months ended March 31, 2020, cash provided by investing activities was
$26.9 million, which consisted of $56.8 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 $0.5 million.
Cash Provided by Financing Activities
During the three months ended March 31, 2021 cash provided by financing
activities was $140.5 million and consisted of net proceeds from the follow-on
offering of $134.6 million and proceeds from employee equity incentive plans of
$5.9 million. During the three months ended March 31, 2020, cash provided by
financing activities was $3.6 million and 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.


                            Contractual Obligations

During the three months ended March 31, 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 ended December 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 with U.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 ended December 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 three months ended March 31, 2021, as compared to the recent accounting pronouncements described in our audited consolidated financial statements and notes for the year ended December 31, 2020, included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020, that are of significance or potential significance to us.
