Overview



We are a clinical-stage biopharmaceutical company applying a precision medicine
approach to acquiring, developing and commercializing life-changing medicines
for underserved patient populations suffering from devastating rare diseases and
cancer. We have a differentiated portfolio of small molecule targeted oncology
product candidates and are advancing two potentially registrational clinical
trials in rare tumor types, as well as several other programs addressing highly
prevalent, genetically defined cancers. Our strategic approach and operational
excellence across research, translational science, and clinical development have
enabled us to rapidly advance our two lead product candidates into late-stage
clinical trials while simultaneously entering into multiple shared-value
partnerships with industry leaders to expand our portfolio. From this
foundation, we are continuing to build a differentiated global biopharmaceutical
company intensely focused on understanding patients and their diseases in order
to develop transformative targeted medicines.

Our most advanced product candidate, nirogacestat, is an oral, small molecule
gamma secretase inhibitor currently in development for the treatment of desmoid
tumors, a rare and often debilitating and disfiguring soft tissue tumor for
which there are currently no therapies approved by the U.S. Food and Drug
Administration, or FDA. We believe nirogacestat may address the significant
limitations associated with existing treatment options and has the potential to
become the first therapy approved by the FDA for both newly diagnosed and
previously treated desmoid tumors. Since we licensed nirogacestat from Pfizer
Inc., or Pfizer, in August 2017, the FDA has granted us Orphan Drug Designation,
Fast Track Designation and Breakthrough Therapy Designation for this indication,
and the European Commission granted Orphan Drug Designation to nirogacestat for
the treatment of soft tissue sarcoma. In May 2019, we announced the initiation
of the DeFi trial, a potentially registrational, double-blind,
placebo-controlled Phase 3 trial evaluating the efficacy, safety and
tolerability of nirogacestat for the treatment of adult patients with
progressing desmoid tumors, and in May 2022, we announced positive topline
results from the DeFi trial. The DeFi trial met its primary endpoint of
improving progression-free survival, or PFS, demonstrating a statistically
significant improvement for nirogacestat over placebo, with a 71% reduction in
the risk of disease progression (hazard ratio (HR) = 0.29 (95% CI: 0.15, 0.55);
p < 0.001). In addition, the trial met all key secondary endpoints, with
nirogacestat demonstrating statistically significant improvements as compared to
placebo in objective response rate, or ORR, and patient-reported outcomes, or
PROs. Nirogacestat was generally well tolerated with a manageable safety
profile. The majority of women of childbearing potential had adverse events
consistent with ovarian dysfunction. Other adverse events were generally
consistent with previously reported data. Additional data are expected to be
presented at a medical conference in the second half of 2022, and SpringWorks
plans to submit a New Drug Application, or NDA, to the FDA in the second half of
2022.

Our second product candidate is mirdametinib, an oral, small molecule MEK
inhibitor currently in development for the treatment of neurofibromatosis type
1-associated plexiform neurofibromas, or NF1-PN, a rare tumor of the peripheral
nerve sheath that causes significant pain and disfigurement, and that most often
manifests in children. We believe that mirdametinib has the potential to offer a
best-in-class profile in order to enable the long-term treatment required for
this patient population, as compared to other MEK inhibitors. As with
nirogacestat, we licensed mirdametinib from Pfizer in August 2017; since then,
the FDA has granted mirdametinib both Orphan Drug Designation and Fast Track
Designation for NF1-PN, and the European Commission has granted mirdametinib
Orphan Drug Designation for NF1. In October 2019, we announced the initiation of
the
                                       17

  Table of Contents
ReNeu trial, a potentially registrational Phase 2b clinical trial of
mirdametinib for pediatric and adult patients with NF1-PN. In February 2021, we
reported interim clinical data from the first 20 adult patients enrolled in the
Phase 2b ReNeu trial, and updated interim clinical data from these patients were
presented in June 2021 at the Children's Tumor Foundation NF Conference. In
November 2021, we announced full enrollment of the ReNeu trial.

We are also evaluating mirdametinib for the treatment of solid tumors harboring
mitogen activated protein kinase, or MAPK, aberrations, in both monotherapy and
combination approaches. In June 2021, we announced the initiation of Phase 1/2
clinical trial of mirdametinib in children and young adults with low-grade
glioma. The study is sponsored by St. Jude Children's Research Hospital and
supported by SpringWorks. In August 2021, we announced the evaluation of
mirdametinib in a Phase 1b/2a platform study sponsored by Memorial Sloan
Kettering Cancer Center and supported by SpringWorks to explore the compound
both as a monotherapy and as a combination therapy in advanced solid tumors
harboring MAPK-activating mutations. The trial, which initiated in the third
quarter of 2021, is initially exploring mirdametinib in two patient cohorts: the
first in combination with fulvestrant, a selective estrogen receptor degrader,
in patients with estrogen receptor-positive metastatic breast cancer with MAPK
alterations (particularly inactivating mutations in NF1), and as a monotherapy
in advanced solid tumors harboring oncogenic MEK1 or MEK2 mutations.

In addition to our late-stage programs in rare oncology indications, we have
expanded our portfolio to develop targeted therapies for the treatment of highly
prevalent hematologic malignancies and genetically defined metastatic solid
tumors. To advance this strategy, we are taking a precision medicine approach in
collaboration with industry leaders. In hematologic malignancies, we have
announced collaborations with GSK plc, formerly GlaxoSmithKline plc, or GSK,
Janssen Biotech, Inc., Pfizer, Allogene Therapeutics, Inc., Precision
BioSciences, Inc., Seagen, Inc., AbbVie Inc and Regeneron Pharmaceuticals, Inc.,
or Regeneron, to develop novel combination regimens of nirogacestat alongside
our collaborators' B-cell maturation antigen, or BCMA, directed therapies for
the treatment of multiple myeloma. In addition to our industry collaborations
with leading BCMA-directed therapy developers, we are working with the Fred
Hutchinson Cancer Research Center and Dana-Farber Cancer Institute to further
explore nirogacestat's ability to potentiate BCMA-directed therapies as part of
sponsored research agreements. In October 2021, we announced an update from our
ongoing clinical collaboration with GSK evaluating nirogacestat in combination
with BLENREP (belantamab mafodotin-blmf) in patients with relapsed or refractory
multiple myeloma, or RRMM; the initiation of an expanded Phase 2 cohort from the
first combination dose level that evaluated 0.95 mg/kg dose of BLENREP every
three weeks plus nirogacestat based on encouraging preliminary data observed in
the Phase 1 cohort. We also announced the addition of two new sub-studies that
will explore BLENREP plus nirogacestat in combination with (i) pomalidomide plus
dexamethasone and (ii) lenalidomide plus dexamethasone in patients with RRMM. In
June 2022, initial clinical data from the Phase 1/2 study evaluating
nirogacestat in combination with BLENREP in patients with RRMM were presented at
the 2022 American Society of Clinical Oncology, or ASCO, Annual Meeting. At the
time of data cut-off, the ORR at low-dose (0.95 mg/kg) BLENREP plus nirogacestat
across the dose exploration, or DE, and cohort expansion, or CE, arms was 38% in
24 patients, with 17% of patients achieving a very good partial response, or
VGPR, or better. The ORR of the BLENREP monotherapy control arm was 50% in 14
patients, with 0% of patients achieving a VGPR or better. An encouraging safety
profile for the combination was observed, with Grade 3 ocular adverse events
occurring in 1/14 (7%) patients in the low-dose BLENREP plus nirogacestat
combination compared to 7/14 patients (50%) in the BLENREP monotherapy arm,
using the Keratopathy Visual Acuity ocular toxicity grading scale. The DE cohort
utilized the CTCAE-5 ocular toxicity grading scale; the low-dose BLENREP plus
nirogacestat combination demonstrated Grade 3 ocular adverse events in 2/10
(20%) patients.

In genetically defined metastatic solid tumors, our current clinical-stage
efforts center on the MAPK pathway. In collaboration with BeiGene, Ltd., or
BeiGene, we are exploring the combination of mirdametinib with BeiGene's
lifirafenib in RAS mutated and other MAPK aberrant cancers. In addition, we are
exploring the use of BGB-3245 in a distinct set of genetically defined BRAF
mutated tumors via MapKure, LLC, or MapKure, an entity jointly owned by us and
BeiGene. In June 2022, we presented initial clinical data from the ongoing Phase
1/2 study evaluating mirdametinib in combination with lifirafenib in patients
with advanced solid tumors with MAPK-activating mutations and the ongoing Phase
1 study evaluating BGB-3245 in patients with advanced solid tumors with BRAF or
RAS mutations, providing evidence of a manageable safety profile and clinical
activity in a variety of solid tumor types with MAPK-activating mutations for
each program.

Together, we believe that our portfolio provides multiple opportunities for
value creation across three distinct categories of oncology programs, each of
which has the potential to provide meaningful clinical benefit to patients
suffering from severe rare diseases and cancer. In our late-stage rare oncology
programs, we believe that our two potentially registrational trials with
nirogacestat and mirdametinib each have best-in-class potential for the patient
populations in which they are being advanced. In our malignant hematology
programs, we believe that nirogacestat has the potential to become a cornerstone
of BCMA combination therapy in multiple myeloma and we are seeking to achieve
this goal by working with partners developing BCMA-targeted agents across
modalities. In our biomarker defined metastatic solid tumor programs, we believe
that our precision medicine approach to cancers harboring mutations in key MAPK
pathway genes, such as RAS and BRAF, provides the opportunity for meaningful
clinical benefit for biomarker defined patient populations.

Furthermore, we intend to continue to build our portfolio by licensing additional programs with strong biological rationales and validated mechanisms of action, such as the TEA Domain, or TEAD, inhibitor program that we in-licensed from Katholieke


                                       18

Universiteit Leuven, or KU Leuven and the Flanders Institute for Biotechnology,
and the portfolio of epidermal growth factor receptor small molecule inhibitors
that we in-licensed from Dana-Farber Cancer Institute. We also plan to continue
using shared-value partnerships to maximize the potential of our therapies to
serve patients. We continue to invest in building leading preclinical
development, clinical development and commercial capabilities and have focused
on structuring innovative partnerships that seek to align incentives and
optimize business outcomes for each party involved. We believe that this
approach will continue to allow us to expand our shared-value relationships with
innovators, maximize the potential of our existing and future portfolio, and
support the building of a scalable and sustainable business focused on the
efficient advancement and commercialization of product candidates that hold the
potential to transform the lives of patients living with severe rare diseases
and cancer.

Recent Developments

In June 2022, as described in greater detail above, initial clinical data from
the Phase 1/2 study evaluating nirogacestat in combination with BLENREP
(belantamab mafodotin-blmf), GSK's antibody drug conjugate targeting BCMA, in
patients with RRMM were presented at the 2022 ASCO Annual Meeting. Long-term
follow-up data from a Phase 2 study sponsored by the National Cancer Institute,
or NCI, evaluating nirogacestat in patients with progressing desmoid tumors were
also presented at the 2022 ASCO Annual Meeting.

In June 2022, we made an additional investment in MapKure and purchased
4,200,000 Series B preferred units of MapKure for $4.2 million pursuant to the
terms of a Series B preferred unit purchase agreement. Pursuant to the
agreement, we are obligated to purchase an additional 2,800,000 Series B
preferred units of MapKure for $2.8 million at a second closing to be held in
the first quarter of 2023.

In May 2022, as described in greater detail above, we announced positive topline
results from the DeFi trial, a double-blind, placebo-controlled Phase 3 trial
evaluating the efficacy, safety and tolerability of nirogacestat in adult
patients with progressing desmoid tumors.

In April 2022, we entered into a clinical trial collaboration and supply
agreement with Regeneron to evaluate nirogacestat in combination with REGN5458,
Regeneron's investigational bispecific antibody targeting CD3 and BCMA, in
patients with RRMM. Pursuant to the terms of the agreement, other than expenses
related to the manufacturing and supply of nirogacestat and certain expenses
related to intellectual property rights, Regeneron is responsible for the
clinical development and will assume all costs associated with the study.

COVID-19 Impact



In December 2019, a novel strain of coronavirus, severe acute respiratory
syndrome coronavirus 2, or SARS-CoV-2, was identified in Wuhan, China. On March
11, 2020, the World Health Organization designated the outbreak of COVID-19, the
disease associated with SARS-CoV-2, as a global pandemic. The disease continues
to spread, including emerging variant strains of COVID-19, in the areas in which
we operate. Governments and businesses around the world have taken unprecedented
actions to mitigate the spread of COVID-19, including, but not limited to,
shelter- in-place orders, quarantines, significant restrictions on travel, as
well as restrictions that prohibit many employees from going to work. Since the
onset of the COVID-19 pandemic, we have undertaken a number of business
continuity measures to mitigate potential disruption to our operations and in
order to preserve the integrity of our research and development programs. To
date, we have not experienced any material disruptions to the execution of the
research and development activities that we currently have underway; however, as
a result of the COVID-19 pandemic, or any impacts of emerging variant strains of
the COVID-19 virus, stagnant vaccination rates and related factors, we may
experience disruptions that could impact our research and development timelines
and outcomes. We will continue to evaluate the impact of the ongoing COVID-19
pandemic, along with the impact of emerging variants, on our business. While the
extent to which COVID-19 impacts our future results will depend on future
developments, including the duration, spread and intensity of the pandemic
(including any resurgences), the impact of emerging variant strains of the
COVID-19 virus and the rollout of COVID-19 vaccines, all of which remain
uncertain and difficult to predict, it is possible that the global pandemic and
its associated economic impacts could result in a material impact to our
business, future financial condition, results of operations and cash flows.

Based on our cash, cash equivalents and marketable securities balance as of
June 30, 2022, of $334.5 million, management estimates that its current
liquidity position will enable it to meet operating expenses through at least
twelve months after the date this Quarterly Report is filed. For further details
on our liquidity position, see the "Results of Operations."

We have not generated any commercial revenue from the sale of products. If our
development efforts for our current product candidates or additional product
candidates that we may develop in the future are successful and can be
commercialized, we may generate revenue in the future from product sales. We may
enter into collaboration and license agreements from time to time that provide
for certain payments due to us. Accordingly, we may generate revenue from such
collaboration or license agreements in the future.

Operating expenses

Research and development expenses

Our research and development expenses consist of expenses incurred in connection with the development of our product candidates. These expenses include:



•employee-related expenses, which include salaries, benefits and stock-based
compensation for our research and development personnel;
•fees paid to consultants for services directly related to our research and
development programs;
•expenses incurred under agreements with third-party contract research
organizations, or CROs, investigative clinical trial sites, academic
institutions and consultants that conduct research and development activities on
our behalf or in collaboration with us;
•costs associated with preclinical studies and clinical trials;
•costs associated with the manufacture of drug substance and finished drug
product for preclinical testing and clinical trials;
•costs associated with technology and intellectual property licenses; and
•an allocated portion of facilities and facility-related costs, which include
expenses for rent and other facility-related costs and other supplies.

External costs for research and development expenses are tracked on a
program-by-program basis. Internal costs for research and development expenses,
such as compensation-related costs for our research and development employees,
as well as depreciation and other indirect costs, are not tracked on a
program-by-program basis.

Expenditures for clinical development, including upfront licensing fees and
milestone payments associated with our product candidates, are charged to
research and development expense as incurred. These expenses consist of expenses
incurred in performing development activities, including salaries and benefits,
materials and supplies, preclinical expenses, clinical trial and related
clinical manufacturing expenses, depreciation of equipment, contract services
and other outside expenses. Costs for certain development activities, such as
manufacturing and clinical trials, are recognized based on an evaluation of the
progress to completion of specific tasks using either time-based measures or
data such as information provided to us by our vendors on actual activities
completed or costs incurred.

We expect our research and development expenses to increase substantially for
the foreseeable future as we continue to invest in activities related to
developing our product candidates and our preclinical programs, and as certain
product candidates advance into later stages of development, including the DeFi
trial and the ReNeu trial. The process of conducting the necessary clinical
trials to obtain regulatory approval is costly and time-consuming, and the
successful development of our product candidates is highly uncertain. As a
result, we are unable to determine the duration and completion costs of our
research and development projects or when and to what extent we will generate
revenue from the commercialization and sale of any of our product candidates.

General and administrative expenses



General and administrative expenses consist primarily of salaries and related
costs, including stock-based compensation, for personnel in executive, finance,
corporate, commercial, business development and administrative functions.
General and administrative expenses also include legal fees relating to patent
and corporate matters; professional fees for accounting, auditing, tax and
administrative consulting services; insurance costs; administrative travel
expenses; and facility-related expenses, which include direct depreciation costs
and allocated expenses for rent and maintenance of facilities and other
operating costs.

We anticipate that our general and administrative expenses will increase in the
future as we increase our headcount to support the continued development of our
product candidates and expand operations to support the organization.

Research and Development

Research and development expense increased by $5.9 million to $38.0 million for
the three months ended June 30, 2022 from $32.1 million for the three months
ended June 30, 2021, an increase of 18%.

The increase in research and development expense was primarily attributable to a
$11.4 million increase in internal costs driven by the growth in employee costs
associated with increases in the number of personnel, including an increase in
stock-based compensation expense, and an increase of $5.3 million in external
costs related to drug manufacturing, clinical trial and other research,
partially offset by an $11.0 million decrease in licensing costs related to the
nonrefundable upfront payment to KU Leuven and VIB LLC, or VIB, for the
in-licensing of the TEAD inhibitor program in May 2021.

General and Administrative



General and administrative expense was $31.0 million for the three months ended
June 30, 2022, an increase of $16.1 million from $14.9 million for the three
months ended June 30, 2021.

The increase in general and administrative expense was primarily attributable to
a $8.2 million increase in internal costs driven by the growth in employee costs
associated with increases in the number of personnel, including an increase in
stock-based compensation expense as we continue to expand our operations to
support the organization, and a $7.2 million increase in information technology
costs and consulting and professional services, including legal, regulatory and
compliance, as we continue to build new capabilities, including commercial.

Research and Development



Research and development expense increased by $22.7 million to $72.1 million for
the six months ended June 30, 2022 from $49.5 million for the six months ended
June 30, 2021, an increase of 46%.

The increase in research and development expense was primarily attributable to a
$21.9 million increase in internal costs driven by the growth in employee costs
associated with increases in the number of personnel, including an increase in
stock-based compensation expense, and an increase of $11.1 million in external
costs related to drug manufacturing, clinical trial and other research,
partially offset by an $11.0 million decrease in licensing costs related to the
nonrefundable upfront payment to KU Leuven and VIB for the in-licensing of the
TEAD inhibitor program in May 2021.

General and Administrative



General and administrative expense was $58.4 million for the six months ended
June 30, 2022, an increase of $31.0 million or 114% from $27.3 million for the
six months ended June 30, 2021.

The increase in general and administrative expense was primarily attributable to
a $17.7 million increase in internal costs driven by the growth in employee
costs associated with increases in the number of personnel, including an
increase in stock-based compensation expense as we continued to expand our
operations to support the organization, and a $12.0 million increase in
information technology costs and consulting and professional services, including
legal, regulatory and compliance, as we continue to build new capabilities,
including commercial.

Liquidity and Capital Resources

Sources of Liquidity



We have incurred operating losses and experienced negative operating cash flows
since our inception and anticipate that we will continue to incur losses for at
least the foreseeable future. Our net loss was $130.9 million and $76.8 million
for the six months ended June 30, 2022 and 2021, respectively. We had an
accumulated deficit of $423.4 million and $292.5 million as of June 30, 2022 and
December 31, 2021, respectively. Based on our cash, cash equivalents and
marketable securities balances as of June 30, 2022, management estimates that
our liquidity position will enable it to meet operating expenses through at
least twelve months after the date that this Quarterly Report is filed. Our
marketable securities consist of high-quality, highly liquid available-for-sale
debt securities including corporate debt securities, U.S. government securities,
non-U.S. government securities, and commercial paper.

June 30, 2021 consisted of proceeds from stock option exercises.

Funding Requirements



Our primary use of cash is to fund operating expenses, primarily our research
and development expenditures. Cash used to fund operating expenses is impacted
by the timing of when we pay these expenses, as reflected in the change in our
outstanding accounts payable, accrued expenses and prepaid expenses.

Our future funding requirements will depend on many factors, including the following:



•the initiation, progress, timing, costs and results of preclinical studies and
clinical trials for our product candidates, including the DeFi trial and the
ReNeu trial;
•the clinical development plans we establish for our product candidates;
•the number and characteristics of product candidates that we develop;
•the outcome, timing and cost of meeting regulatory requirements established by
the FDA, the European Medicines Agency, or EMA, and other comparable foreign
regulatory authorities;
•the terms of our existing and any future license or collaboration agreements we
may choose to enter into, including the amount of upfront, milestone and royalty
obligations;
•the other costs associated with in-licensing new technologies, such as any
increased costs of research and development and personnel;
•the cost of filing, prosecuting, defending and enforcing our patent claims and
other intellectual property rights;
                                       23

  Table of Contents
•the cost of defending intellectual property disputes, including patent
infringement actions brought by third parties against us or our product
candidates;
•the effect of competing technological and market developments;
•the cost and timing of completion of commercial-scale outsourced manufacturing
activities;
•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; and
•the degree of commercial success achieved following the successful completion
of development and regulatory approval activities for a product candidate.

We will need additional funds to meet operational needs and capital requirements
for clinical trials, other research and development expenditures, commercial
activities and business development efforts. Because of the numerous risks and
uncertainties associated with the development and commercialization of our
product candidates, we are unable to estimate the amounts of increased capital
outlays and operating expenditures associated with our current and anticipated
clinical studies.

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. To the extent that we raise additional capital through
the sale of equity or convertible debt securities, current ownership interests
will be diluted, and the terms of these securities may include liquidation or
other preferences that adversely affect rights of 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



In October 2018, we entered into a lease for our corporate headquarters in
Stamford, CT. In January 2022, we amended this lease agreement to extend the
lease term through April 2028, with two five-year renewal options or one
ten-year renewal option. Pursuant to the amendment, we are entitled to $0.5
million in tenant allowances, which may be used to offset certain future capital
expenditures, and the lease payments increase by 2.5% in each year commencing
December 1, 2022. The amendment was treated as a modification and the lease
liability and operating lease right-of-use asset were updated to reflect minimum
lease payments and any other adjustments.

As of June 30, 2022, the Company's future lease payments under non-cancelable leases with terms greater than one year are as follows:



(in thousands)                            Operating Leases
2022                                     $             213
2023                                                 1,262
2024                                                 1,155
2025                                                 1,184
2026 and thereafter                                  2,881
Total lease payments                                 6,695
Less: imputed interest                                (913)
Present value of lease liabilities       $           5,782


During the six months ended June 30, 2022, there were no other material changes
to our contractual obligations and commitments than those described under the
heading "Management's Discussion and Analysis of Financial Condition and Results
of Operations-Contractual Obligations" in Part II Item 6. of our 2021 Form 10-K.

We enter into contracts in the normal course of business for clinical trials,
preclinical studies, manufacturing and other services and products for operating
purposes. These contracts generally provide for termination following a certain
period after notice and therefore we believe that our non-cancelable obligations
under these agreements are not material.

Critical Accounting Policies and Use of Estimates



This discussion and analysis of our financial condition and results of
operations is based on our condensed consolidated financial statements, which
have been prepared in accordance with accounting principles generally accepted
in the United States. The preparation of these condensed consolidated financial
statements requires us to make estimates and assumptions that affect the
reported amounts and the related disclosures in the financial statements and
accompanying notes. These accounting policies involve critical accounting
estimates because they are particularly dependent on estimates and assumptions
made by management about matters that are uncertain at the time the accounting
estimates are made. We base our estimates on historical experience, known trends
and other market-specific or relevant factors that we believe to be reasonable
under the circumstances, the results of which form the basis of making
judgments; However, because future events and their effects cannot be determined
with certainty, actual results may differ from those estimates, judgments or
assumptions, and such differences could be material. On an ongoing basis, we
evaluate our estimates, judgments and assumptions, and adjust those estimates,
judgments and assumptions when facts or circumstances change. Changes in
estimates are recorded in the period in which they become known. Although we
believe that these estimates are reasonable actual results could differ.

We describe our significant accounting policies in Note 3, Summary of
Significant Accounting Policies, of the notes to the financial statements
included in our 2021 Form 10-K. We discuss our critical accounting estimates in
Item 7, Management's Discussion and Analysis of Financial Condition and Results
of Operations, in our 2021 Form 10-K. There have been no changes in our
significant accounting policies or critical accounting estimates during the six
months ended June 30, 2022.
