The following discussion and analysis of our financial condition and results of
operations should be read in conjunction with our consolidated financial
statements and related notes appearing elsewhere in this Quarterly Report and
our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, as
filed with the SEC on March 29, 2022 (2021 Form 10-K). Some of the information
contained in this discussion and analysis or set forth elsewhere in this
Quarterly Report, including information with respect to our plans and strategy
for our business, includes forward-looking statements that involve risks and
uncertainties. As a result of many factors, including those factors set forth in
the "Item 1.A. Risk Factors" section of this Quarterly Report and our other
filings with the SEC, our actual results could differ materially from the
results described in or implied by the forward-looking statements contained in
the following discussion and analysis.

Overview



We are a clinical stage biopharmaceutical company focused on creating precisely
targeted therapies for patients with cancer. We leverage our team's deep
expertise in chemistry and structure-based drug design to develop innovative
small molecules that are designed with the aim to overcome the limitations of
existing therapies for "clinically proven" kinase targets, or those kinase
targets for which others have developed established, approved therapies that are
used in the clinical setting. By addressing the limitations of existing
therapies, we believe our programs have the potential to drive deeper, more
durable responses with minimal adverse events. We believe these potential
benefits will support opportunities for clinical utility earlier in the
treatment paradigm.

We focus our discovery and development efforts on small molecule inhibitors of
kinases, a class of cellular targets that can play a central role in cancer
growth and proliferation. In particular, we focus on clinically proven kinase
targets. Currently available kinase inhibitors face multiple limitations, which
can include (i) kinase resistance, or the emergence of new mutations in the
kinase target that can enable resistance to existing therapies, (ii) kinase
selectivity, or the potential for existing therapies to inhibit other
structurally similar kinase targets and lead to off-target adverse events, and
(iii) limited brain penetrance, or the ability for the therapy to treat disease
that has spread or metastasized to the brain. By prioritizing target
selectivity, we believe our drug candidates have the potential to overcome
resistance, avoid dose-limiting off-target adverse events, address brain
metastases, and drive more durable responses.

We are advancing a robust pipeline of product candidates with parallel lead
programs in cancers driven by genomic alterations in ROS proto-oncogene 1 (ROS1)
and ALK (i.e., ROS1-positive and ALK-positive, respectively), a new program in
cancers driven by genomic alterations in human epidermal growth factor receptor
2 (HER2), along with multiple discovery-stage research programs. We hold
worldwide development and commercialization rights to our product candidates.

NVL-520



Our first lead product candidate, NVL-520, is a novel ROS1-selective inhibitor
designed with the aim to address the clinical challenges of emergent treatment
resistance, central nervous system (CNS)-related adverse events, and brain
metastases that may limit the use of currently available ROS1 tyrosine kinase
inhibitors (TKIs). Preclinical data has shown that NVL-520 was brain-penetrant,
inhibited wild-type ROS1 fusions, remained active in the presence of mutations
conferring resistance to approved and investigational ROS1 inhibitors, and
displayed strong selectivity for both wild-type ROS1 and its resistance variants
as compared to the structurally related tropomyosin receptor kinase B (TRKB),
thereby indicating the potential to minimize the off-target TRKB-related CNS
adverse events.

We are currently enrolling patients in the ongoing Phase 1 portion of our
ARROS-1 clinical trial, a first-in-human Phase 1/2, multicenter, open-label,
dose-escalation and expansion study evaluating NVL-520 as an oral monotherapy in
patients with advanced ROS1-positive non-small cell lung cancer (NSCLC) and
other solid tumors. ARROS-1 is comprised of two study phases, beginning with a
Phase 1 dose-escalation portion to evaluate the safety, tolerability and
recommended Phase 2 dose (RP2D) of NVL-520 in patients with advanced
ROS1-positive NSCLC or other solid tumors who have received at least one prior
ROS1 TKI or any prior therapy, respectively. Other Phase 1 objectives include
characterizing the pharmacokinetic profile and evaluating preliminary anti-tumor
activity of NVL-520. Once the RP2D is determined, the study may transition
directly into a Phase 2 portion designed to evaluate the RP2D in patients with
advanced ROS1-positive NSCLC and other solid tumors and to support potential
registration of NVL-520 in both ROS1-positive patients with NSCLC who are
TKI-naïve and who have been previously treated with ROS1 kinase inhibitors.

We recently announced preliminary data from the Phase 1 dose-escalation portion of the ARROS-1 clinical trial.



The preliminary dose-escalation data were based on an enrollment cut-off date of
September 1, 2022, and a data cut-off date of September 13, 2022. Thirty-five
patients were enrolled, of which 34 patients had confirmed ROS1-positive NSCLC
and 51% (18/35) had a history of CNS metastases.

                                       14

The patient population was heavily pre-treated:

77% (27/35) had received three or more prior lines of anti-cancer therapy;

71% (25/35) had two or more prior ROS1 TKIs and one or more lines of chemotherapy; and

80% (28/35) had received a ROS1 TKI other than crizotinib or entrectinib, including lorlatinib (57%, 20/35) or repotrectinib (34%, 12/35).

Patients were treated with NVL-520 across five evaluated dose levels ranging from 25 mg once daily (QD) to 125 mg QD, and preliminary safety and pharmacokinetics of NVL-520 were evaluated as of the data cut-off date. Key findings as of the data cut-off date include:

NVL-520 demonstrated exposure above all target efficacy thresholds (ROS1 wild type and ROS1 G2032R in both the periphery and in the CNS).

Favorable pharmacokinetics and low intra-cohort patient pharmacokinetic variability were observed, with exposure increasing with increasing dose level and half-life supportive of once daily dosing.

No dose-limiting toxicities, treatment-related serious adverse events, treatment-related dizziness, or adverse events leading to dose reduction or discontinuation were observed as of the data cut-off date in the 35 patients enrolled.

Most treatment-related adverse events (TRAEs) were low-grade and manageable, with the most frequent TRAE being grade 1 fatigue reported in 11% (4/35) of patients.



As of the data cut-off date, 21 patients with NSCLC were response-evaluable by
investigator assessment with duration of treatment ranging from one to more than
eight months (median 3.6 months). Objective responses (RECIST 1.1) were observed
across all dose levels evaluated, including in:


Heavily pre-treated patients: Partial Responses (PRs) were observed in 48%
(10/21) of all response-evaluable patients, with 76% (16/21) continuing on
treatment. Responses were observed in 53% (9/17) of patients who received two or
more prior TKIs and one or more prior lines of chemotherapy, in 50% (9/18) of
patients previously treated with lorlatinib or repotrectinib, and across all
dose levels evaluated.


Patients with ROS1 G2032R resistance mutation: Of nine patients with known ROS1
G2032R resistance mutation, responses were observed in 78% (7/9), including in
two of three patients previously treated with repotrectinib, and tumor shrinkage
was observed in 100% (9/9). Notably, complete clearance of G2032R allele was
observed in all seven patients with G2032R detected on central ctDNA analysis.


Patients with CNS metastases: Intracranial PRs were observed in 100% (3/3)
patients with measurable (>10 mm) CNS metastases. Responses were observed in 73%
(8/11) of patients with a history of CNS metastases, and no CNS progression was
observed in any of the 35 treated patients.

As of the data cut-off date, 76% (16/21) of response-evaluable patients continued on NVL-520 treatment. Enrollment in the Phase 1 portion of the trial is ongoing.



NVL-655

Our second lead product candidate, NVL-655, is a brain-penetrant ALK-selective
inhibitor designed with the aim to address the clinical challenges of emergent
treatment resistance, CNS-related adverse events, and brain metastases that may
limit the use of first-, second-, and third-generation ALK inhibitors.
Preclinical data has shown that NVL-655 was brain-penetrant, inhibited wild-type
ALK fusions, remained active in the presence of mutations conferring resistance
to approved and investigational ALK inhibitors, and displayed strong selectivity
for both wild-type ALK and its resistance variants as compared to the
structurally related TRKB, thereby indicating the potential to minimize
off-target TRKB-related CNS adverse events.

We also announced new preclinical data for NVL-655 further characterizing its
preclinical profile in TKI-resistant models of ALK-positive cancers harboring
single and compound ALK resistance mutations. Notably, NVL-655 induced
regression in an in vivo model derived from a patient with ALK fusion-positive
NSCLC harboring G1202R/L1196M compound mutation after disease progression on
sequential crizotinib, alectinib and lorlatinib treatment.

We are currently enrolling patients in the ongoing Phase 1 portion of our
ALKOVE-1 clinical trial, a first-in-human Phase 1/2, multicenter, open-label,
dose-escalation and expansion study evaluating NVL-655 as an oral monotherapy in
patients with advanced

                                       15

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

Table of Contents





ALK-positive NSCLC and other solid tumors. In June 2022, we announced that the
first patient was dosed with NVL-655 in the ALKOVE-1 trial. ALKOVE-1 is
comprised of two study phases, beginning with a Phase 1 dose-escalation portion
to evaluate the safety, tolerability and RP2D of NVL-655 in patients with
advanced ALK-positive NSCLC or other solid tumors who have received at least one
prior ALK TKI or at least one prior systemic anticancer therapy, respectively.
Other Phase 1 objectives include characterizing the pharmacokinetic profile and
evaluating preliminary anti-tumor activity of NVL-655. Once the RP2D is
determined, the study may transition directly into a Phase 2 portion designed to
evaluate the preliminary activity of NVL-655 in various cohorts of ALK-positive
NSCLC patients and patients with other solid tumors, with the potential to
expand cohort sizes further into potentially registrational cohorts in
collaboration with the FDA.

NVL-330



In September 2022, we announced the nomination of our newest product candidate,
NVL-330, a brain-penetrant HER2-selective inhibitor designed with the aim to
address the combined medical need of treating tumors driven by HER2ex20,
avoiding treatment-limiting adverse events due to off-target inhibition of
wild-type EGFR, and treating brain metastases. HER2ex20 are oncogenic driver
mutations in an estimated 1-3% of NSCLC, yet there are limited therapeutic
options targeting these mutations.

In addition, we announced preliminary preclinical data demonstrating that
NVL-330 potently inhibited HER2ex20 in cell-based assays and was highly
selective for HER2ex20 over the structurally related wild-type EGFR. This
selectivity is a critical aspect of NVL-330's design given that inhibition of
wild-type EGFR is associated with dose-limiting side effects including skin rash
and gastrointestinal toxicity.

Furthermore, the demonstrated preclinical brain penetrance and intracranial
activity of NVL-330 suggests the potential for treating or preventing brain
metastases. Brain metastases are present at diagnosis in an estimated 19% of
HER2 mutant-positive NSCLC patients, and more patients will develop them during
treatment.

Other Candidates

In addition to our lead programs and our new HER2ex20 development program, we
have prioritized a number of additional small molecule research programs
following an assessment of medical need, including an ALK IXDN program designed
with the aim to address emerging compound resistance mutations. Research for
these programs is ongoing. We do not expect to nominate any further drug
candidates for these programs in 2022.


Since commencing significant operations in 2018, we have focused substantially
all of our efforts and financial resources on research and development
activities for our programs, including NVL-520, NVL-655 and NVL-330,
establishing and maintaining our intellectual property portfolio, organizing and
staffing our company, business planning, raising capital, and providing general
and administrative support for these operations. We do not have any products
approved for sale and have not generated revenue from product sales or any other
source.

On August 2, 2021, we completed an initial public offering (IPO) of our common
stock pursuant to which we issued and sold 10,612,500 shares of Class A common
stock and 600,000 shares of Class B common stock, including the exercise in full
by the underwriters of their option to purchase 1,462,500 additional shares of
Class A common stock, at a public offering price of $17.00 per share. We
received net proceeds of approximately $174.3 million after deducting
underwriting discounts and commissions and offering costs. Prior to the IPO, we
funded our operations primarily with proceeds from the sales of convertible
preferred stock, the issuance of convertible notes (which converted to
convertible preferred stock in 2018) and debt financing from stockholders (which
was settled in convertible preferred stock in February 2021). On November 3,
2022, we issued and sold 7,895,522 shares of Class A common stock, including the
exercise in full by the underwriters of their option to purchase additional
shares of Class A common stock, in a follow-on public offering at a public
offering price of $33.50 per share, resulting in proceeds of $248.6 million
after underwriting discounts and commission but before deducting offering costs.

Since our inception, we have incurred significant operating losses. Our ability
to generate product revenue sufficient to achieve profitability will depend
heavily on the successful development and eventual commercialization of our
product candidates. We reported net losses of $55.7 million for the nine months
ended September 30, 2022, and $46.3 million for the year ended December 31,
2021. As of September 30, 2022, we had an accumulated deficit of $134.0 million.
We expect to incur significant expenses at an increasing rate and increasing
operating losses for the foreseeable future. We expect our expenses and capital
requirements will increase substantially in connection with ongoing activities,
particularly if and as we:

continue to advance our parallel lead programs, NVL-520 and NVL-655, in clinical development;

continue to advance our newly nominated program, NVL-330, in preclinical development;


                                       16

•

advance the development of our discovery programs, including our ALK IXDN program;

expand our pipeline of product candidates through our own product discovery and development efforts;

seek to discover and develop additional product candidates;

seek regulatory approvals for any product candidates that successfully complete clinical trials;


establish a sales, marketing and distribution infrastructure to commercialize
any approved product candidates and related additional commercial manufacturing
costs;

implement operational, financial and management systems;

attract, hire and retain additional clinical, scientific, management and administrative personnel;

maintain, expand, protect and enforce our intellectual property portfolio, including patents, trade secrets and know how;

acquire or in-license other product candidates and technologies; and

operate as a public company.



We will not generate revenue from product sales unless and until we successfully
complete clinical development and obtain regulatory approval for our product
candidates. If we obtain regulatory approval for any of our product candidates
and do not enter into a commercialization partnership, we expect to incur
significant expenses related to developing our internal commercialization
capability to support product sales, marketing and distribution. Further, we
expect to continue to incur additional costs associated with operating as a
public company.

As a result, we will need substantial additional funding to support our
continuing operations and pursue our growth strategy. Until such time as we can
generate significant revenue from product sales, if ever, we expect to finance
our operations through a combination of equity offerings, debt financings,
collaborations, strategic alliances and marketing, distribution or licensing
arrangements. We may be unable to raise additional funds or enter into such
other agreements or arrangements when needed on favorable terms, or at all. Our
ability to raise additional funds may be adversely impacted by potential
worsening global economic conditions and the disruptions to, and volatility in,
the credit and financial markets in the U.S. and worldwide, including inflation
and interest rate fluctuations, as well as concerns related to the COVID-19
pandemic and geopolitical events, including civil or political unrest (such as
the ongoing military conflict between Ukraine and Russia). Our failure to obtain
sufficient funds on acceptable terms when needed could have a material adverse
effect on our business, results of operations or financial condition, including
requiring us to have to delay, reduce or eliminate our product development or
future commercialization efforts. Insufficient liquidity may also require us to
relinquish rights to product candidates at an earlier stage of development or on
less favorable terms than we would otherwise choose. The amount and timing of
our future funding requirements will depend on many factors, including the pace
and results of our development efforts.

Because of the numerous risks and uncertainties associated with pharmaceutical
product development, we are unable to accurately predict the timing or amount of
increased expenses or when or if we will be able to achieve or maintain
profitability. Even if we are able to generate product sales, we may not become
profitable. If we fail to become profitable or are unable to sustain
profitability on a continuing basis, then we may be unable to continue our
operations at planned levels and be forced to reduce or terminate our
operations.

We believe that our cash, cash equivalents and marketable securities, including
the proceeds from our follow-on public offering in November 2022, will be
sufficient to fund our operating expenses and capital expenditure requirements
into the second half of 2025. Our cash, cash equivalents and marketable
securities will not be sufficient to fund any of our product candidates through
regulatory approval, and we anticipate needing to raise additional capital to
complete the development and commercialization of our product candidates. See
"-Liquidity and Capital Resources."

The global COVID-19 pandemic and other significant geopolitical factors,
including the ongoing military conflict between Russia and Ukraine, continue to
rapidly evolve. The extent of the impact of these events on our business,
operations and development timelines and plans remains uncertain, and will
depend on certain developments, including their impact on our development
activities, clinical trial enrollment, future trial sites, CROs, third-party
manufacturers, and other third parties with whom we do business, as well as
their impact on regulatory authorities and our key scientific and management
personnel. The ultimate impact of these events is highly uncertain and subject
to change. We will continue to monitor these situations and may take further
actions that alter our operations, including those that may be required by
federal, state or local authorities, or that we determine are in the best
interests of our employees and other third parties with whom we do business. At
this point, the extent to which the COVID-19 pandemic and other

significant geopolitical factors may affect our business, operations and development timelines and plans, including the resulting impact on our expenditures and capital needs, and on our ability to initiate and conduct clinical trials in the timelines we expect, remains uncertain.

Components of Our Results of Operations

Operating expenses

Our operating expenses are comprised of research and development expenses and general and administrative expenses.

Research and development expenses



Research and development expenses consist primarily of costs incurred for our
research activities, including our drug discovery efforts, and the development
of our product candidates, which include:

personnel-related costs, including salaries, benefits and stock-based compensation expense, for employees engaged in research and development functions;

expenses incurred in connection with our research programs, including under agreements with third parties, such as consultants, contractors and CROs; and

the cost of developing and scaling our manufacturing process and manufacturing drug substance and drug product for use in our research and preclinical and clinical studies, including under agreements with third parties, such as consultants, contractors and contract manufacturing organizations (CMOs).



We track our direct external research and development expenses on a
program-by-program basis. These consist of costs that include fees, reimbursed
materials, and other costs paid to consultants, contractors, CMOs, and CROs in
connection with our preclinical, clinical and manufacturing activities. We do
not allocate employee costs, costs associated with our discovery efforts, and
facilities expenses, including depreciation or other indirect costs, to specific
product development programs because these costs are deployed across multiple
programs and, as such, are not separately classified.

We expect that our research and development expenses will increase substantially
as we continue to advance NVL-520 and NVL-655 in clinical development, advance
NVL-330 in preclinical development, and expand our discovery, research and
preclinical activities in the near term and in the future. Although we are
currently enrolling patients in the Phase 1 portions of our ARROS-1 and ALKOVE-1
clinical trials, at this time, we cannot accurately estimate or know the nature,
timing and costs of the efforts that will be necessary to complete the
preclinical and clinical development of any product candidates we may develop. A
change in the outcome of any number of variables with respect to product
candidates we may develop could significantly change the costs and timing
associated with the development of that product candidate. The duration, costs
and timing of preclinical studies and clinical trials and development of our
product candidates will depend on a variety of factors, including:


the timing and progress of development activities relating to NVL-520, NVL-655,
NVL-330 and any future product candidates from our ALK IXDN and other discovery
programs, including any additional costs that may result from delays in
enrollment or other factors;

the number and scope of preclinical and clinical programs we decide to pursue;

our ability to maintain our current research and development programs and to establish new ones;

establishing an appropriate safety profile with IND-enabling toxicology studies;

successful patient enrollment in, and the initiation and completion of, clinical trials;

the number of trials required for regulatory approval;

the countries in which the trials are conducted;

the length of time required to enroll eligible subjects and initial clinical trials;

the number of subjects that participate in the trials and per subject trial costs;

potential additional safety monitoring requested by regulatory authorities;

the duration of subject participation in the trials and follow-up;


                                       18

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

•

the successful completion of clinical trials with safety, tolerability and efficacy profiles that are satisfactory to applicable regulatory authorities;

the receipt of approvals from applicable regulatory authorities;

the timing, receipt and terms of any marketing approvals and post-marketing approval commitments from applicable regulatory authorities;


the extent to which we establish collaborations, strategic partnerships or other
strategic arrangements with third parties, if any, and the performance of any
such third party;

establishing commercial manufacturing capabilities or making arrangements with CMOs;

development and timely delivery of commercial-grade drug formulations that can be used in our clinical trials and for commercial launch; and

obtaining, maintaining, defending and enforcing patent claims and other intellectual property rights.



Any changes in the outcome of any of these factors could significantly impact
the costs, timing and viability associated with the development of our product
candidates. For example, if the FDA or another regulatory authority were to
delay our planned start of clinical trials or require us to conduct clinical
trials or other testing beyond those that we currently expect 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 of that product candidate.

General and administrative expenses



General and administrative expenses consist primarily of salaries and related
costs, including stock-based compensation, for personnel in executive, finance
and administrative functions. General and administrative expenses also include
professional fees for legal, patent, consulting, investor and public relations
and accounting and audit services. We anticipate that our general and
administrative expenses will increase in the future as we increase our headcount
to support our continued research activities and development of our product
candidates. We also anticipate that we will continue to incur increased
accounting, audit, legal, regulatory, compliance, and director and officer
insurance costs as well as investor and public relations expenses associated
with operating as a public company.

Other income (expense)

Change in fair value of preferred stock tranche rights



Pursuant to the terms of our Series A Preferred Stock Purchase Agreement, we
provided investors with the right and obligation to participate in subsequent
closings of Series A convertible preferred stock upon the achievement of certain
strategic milestones or as determined by the Series A investors (the Series A
Tranche Rights). These Series A Tranche Rights met the definition of a
freestanding financial instrument as the Series A Tranche Rights were legally
detachable and separately exercisable from the Series A convertible preferred
stock. The Series A Tranche Rights were initially classified as a liability on
our consolidated balance sheet that we remeasured to fair value at each
reporting date, and we recognized changes in fair value of the Series A Tranche
Rights as a component of other income (expense) in our consolidated statements
of operations and comprehensive loss. All Series A Tranche Rights were settled
by March 31, 2021.

Other income (expense), net

Other income (expense), net, consists of interest income, interest expense and other income (expense) unrelated to our core operations.

related to NVL-520 of $2.2 million was primarily due to increased clinical and
manufacturing costs as we progressed NVL-520 into the Phase 1 portion of our
ARROS-1 clinical trial. The increase in direct research and development expenses
related to NVL-655 of $0.8 million was primarily due to an increase in clinical
and manufacturing costs as we progressed NVL-655 into the Phase 1 portion of our
ALKOVE-1 clinical trial. The increase in direct research and development
expenses related to our discovery programs of $0.6 million was primarily due to
progress of our discovery programs. The increase in personnel-related expenses
of $1.6 million was primarily due to an increase in headcount. Personnel-related
expenses for the three months ended September 30, 2022 and 2021, included
stock-based compensation expense of $1.0 million and $0.5 million, respectively.

Research and development expenses were $40.9 million for the nine months ended
September 30, 2022, compared to $22.4 million for the nine months ended
September 30, 2021. The increase in direct research and development expenses
related to NVL-520 of $7.1 million was primarily due to increased manufacturing
and clinical costs as we progressed NVL-520 into the Phase 1 portion of our
ARROS-1 clinical trial. The increase in direct research and development expenses
related to NVL-655 of $1.7 million was primarily due to increased clinical costs
as we progressed NVL-655 into the Phase 1 portion of our ALKOVE-1 clinical
trial. The increase in direct research and development expenses related to our
discovery programs of $2.6 million was primarily due to progress of our
discovery programs. The increase in personnel-related expenses of $6.6 million
was primarily due to an increase in headcount. Personnel-related expenses for
the nine months ended September 30, 2022 and 2021, included stock-based
compensation expense of $3.0 million and $0.8 million, respectively. The
increase in other of $0.5 million is due to costs to support our growing
research and development function.

General and administrative expenses

General and administrative expenses for the nine months ended September 30,
2022, were $15.9 million compared to $6.1 million for the nine months ended
September 30, 2021. The increase in personnel-related expenses of $5.6 million
was primarily due to an increase in headcount. Personnel-related expenses for
the nine months ended September 30, 2022 and 2021, included stock-based
compensation expense of $4.3 million and $1.4 million, respectively. The
increase in professional and consultant fees of $1.2 million was primarily due
to increased accounting, audit and legal fees. The increase in other of $3.1
million was primarily due to increased insurance and other costs associated with
operating as a public company and to support our growing organization.

Other income (expense)

Change in fair value of preferred stock tranche rights



The change in the fair value of the Series A Tranche Rights for the nine months
ended September 30, 2021, was primarily due to the change in the fair value of
our Series A convertible preferred stock during that period. All Series A
Tranche Rights were settled by March 31, 2021.

Other income, net

Other income, net consisted primarily of interest income for the nine months ended September 30, 2022, resulting from investing our cash balances. Other income, net was not significant for the nine months ended September 30, 2021.

Liquidity and Capital Resources



Since our inception, we have incurred significant operating losses. We have not
yet commercialized any of our product candidates and we do not expect to
generate revenue from sales of any product candidates for the foreseeable
future, if at all. Through September 30, 2022, we have funded our operations
primarily with proceeds from the sales of convertible preferred stock, the
issuance of convertible notes (which converted to convertible preferred stock in
2018), debt financing from stockholders and our IPO. As of September 30, 2022,
we had cash, cash equivalents and marketable securities of $240.1 million.

On August 10, 2022, we entered into a Sales Agreement (the Sales Agreement) with
Cowen and Company, LLC (Cowen) under which we may issue and sell shares of our
Class A common stock, from time to time, having an aggregate offering price of
up to $150.0 million through Cowen as our Sales Agent (the ATM Facility). We
will pay Cowen a commission of up to 3% of the gross proceeds of any shares of
Class A common stock sold pursuant to the Sales Agreement. As of September 30,
2022, we have not sold any shares of our Class A common stock pursuant to the
Sales Agreement. On October 31, 2022, we entered into an Amendment No. 1 to the
Sales Agreement with Cowen (the Sales Agreement Amendment). The Sales Agreement
Amendment was effective immediately and reduced the maximum aggregate offering
price of the Class A common stock that the Company may sell under the ATM
Facility to $135.0 million.

Operating activities

During the nine months ended September 30, 2022, operating activities used $47.2
million of cash, resulting from our net loss of $55.7 million, partially offset
by net non-cash charges of $7.8 million and by net cash provided by changes in
our operating assets and liabilities of $0.8 million. Net cash provided by
changes in our operating assets and liabilities for the nine months ended
September 30, 2022, consisted primarily of an increase in accounts payable and
accrued expenses of $2.7 million, partially offset by an increase in other
assets and prepaid expenses and other current assets of $1.1 million and $0.8
million, respectively.

During the nine months ended September 30, 2021, operating activities used $27.0
million of cash, resulting from our net loss of $29.0 million and net cash used
by changes in our operating assets and liabilities of $0.8 million, partially
offset by net non-cash charges of $2.8 million. Net cash used by changes in our
operating assets and liabilities for the nine months ended September 30, 2021
consisted primarily of an increase in other assets of $2.8 million and an
increase in prepaid expenses and other current assets of $0.4 million, partially
offset by an increase in accounts payable and accrued expenses of $2.5 million.

Investing activities

During the nine months ended September 30, 2022, net cash provided by investing activities was $54.7 million, due to proceeds from sales and maturities of marketable securities of $105.0 million, partially offset by purchases of marketable securities of $50.3 million.

During the nine months ended September 30, 2021, net cash used in investing activities was $56.6 million, due to purchases of marketable securities.

Financing activities



During the nine months ended September 30, 2022, net cash provided by financing
activities was $0.2 million, consisting of proceeds from the exercise of common
stock options of $0.6 million, partially offset by payments of insurance costs
financed by a third-party.

During the nine months ended September 30, 2021, net cash provided by financing
activities was $319.2 million, consisting of proceeds from our IPO, net of
underwriting discounts and commissions of $177.3 million and proceeds from the
issuance of our Series A and Series B convertible preferred stock of $144.7
million, partially offset by payment of IPO costs of $2.6 million.

Funding Requirements



We expect our expenses to increase substantially in connection with our ongoing
activities, particularly as we advance the preclinical and clinical activities
and clinical trials for our product candidates in development. In addition, we
expect to continue to incur additional costs associated with operating as a
public company. The timing and amount of our operating expenditures will depend
largely on:


the initiation, progress, timing, costs and results of preclinical studies and
clinical trials for our discovery programs and product candidates, including the
advancement of NVL-520, NVL-655 and NVL-330 throughout clinical development;

                                       23

  Table of Contents



•

the clinical development plans we establish for our product candidates, including NVL-520, NVL-655 and NVL-330;

the number and characteristics of product candidates that we discover and develop through our product discovery and research efforts;

the terms of any collaboration agreements we may choose to pursue;

the outcome, timing and cost of meeting regulatory requirements established by the FDA, the EMA and other comparable foreign regulatory authorities;

the cost of filing, prosecuting, defending and enforcing our patent claims and other intellectual property rights;

the cost of defending intellectual property disputes, including patent infringement actions brought by third parties against us;

the effect of competing technological and market developments;

the cost and timing of completion of commercial-scale outsourced manufacturing activities; and


the cost of establishing sales, marketing and distribution capabilities for any
product candidates for which we may receive regulatory approval in regions where
we choose to commercialize our products on our own.

As of September 30, 2022, we had cash, cash equivalents and marketable
securities of $240.1 million. On November 3, 2022, we received proceeds of
$248.6 million after underwriting discounts and commission but before deducting
offering costs. We expect that our cash, cash equivalents and marketable
securities, including the proceeds from our follow-on public offering in
November 2022, will be sufficient to fund our operating expenses and capital
expenditure requirements into the second half of 2025. Our cash, cash
equivalents and marketable securities will not be sufficient to fund any of our
product candidates through regulatory approval, and we anticipate needing to
raise additional capital to complete the development and commercialization of
our product candidates. Our estimate as to how long we expect our cash, cash
equivalents and marketable securities to fund our operations is based on
assumptions that may prove to be wrong, and we could utilize our available
capital resources sooner than we expect. Because of the numerous risks and
uncertainties associated with research, development and commercialization of
pharmaceutical product candidates, we are unable to estimate the exact amount of
our working capital requirements. Our future funding requirements will depend on
and could increase significantly as a result of many factors, including those
listed above.

Until such time, if ever, as we can generate substantial product revenue, we
expect to finance our operations through a combination of equity offerings, debt
financings, collaborations, strategic alliances and marketing, distribution or
licensing arrangements. We do not currently have any committed external source
of funds. To the extent that we raise additional capital through the sale of
equity or convertible debt securities, the ownership interest of our common
stockholders will be diluted, and the terms of these securities may include
liquidation or other preferences that adversely affect the rights of our common
stockholders. Debt financing and preferred equity financing, if available, may
involve agreements that include covenants limiting or restricting our ability to
take specific actions, such as incurring additional debt, making acquisitions or
capital expenditures or declaring dividends. If we raise additional funds
through collaborations, strategic alliances or marketing, distribution or
licensing arrangements with third parties, we may have to relinquish valuable
rights to our technologies, future revenue streams, research programs or product
candidates or grant licenses on terms that may not be favorable to us. If we are
unable to raise additional funds through equity or debt financings or other
arrangements when needed, we may be required to delay, limit, reduce or
terminate our research, product development or future commercialization efforts
or grant rights to develop and market product candidates that we would otherwise
prefer to develop and market ourselves.

Contractual Obligations and Other Commitments

During the three and nine months ended September 30, 2022, there were no material changes to our contractual obligations and commitments from those described under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations - Contractual Obligations and Other Commitments" included in our 2021 Form 10-K.

Critical Accounting Policies and Significant Judgments and Estimates



We prepare our consolidated financial statements in accordance with accounting
principles generally accepted in the United States of America. The preparation
of financial statements requires us to make estimates and assumptions that
affect the reported amounts of assets, liabilities, revenues, costs and expenses
and related disclosures. We base our estimates on historical experience and on
various other assumptions that we believe to be reasonable under the
circumstances. Actual results could differ significantly from the estimates made
by our management.

There have been no material changes to our critical accounting policies and estimates from those disclosed in our consolidated financial statements and the related notes and other financial information included in our 2021 Form 10-K.

Recently Issued and Adopted Accounting Pronouncements



A description of recently issued accounting pronouncements that may potentially
impact our financial position and results of operations is disclosed in Note 2
