The following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed here. Factors that could cause or contribute to such differences include, but are not limited to those discussed in this section as well as factors described in Part II, Item 1A "Risk Factors."

Overview

Strategic Direction of Our Business

Nektar Therapeutics is a research-based biopharmaceutical company that discovers
and develops innovative new medicines in areas of high unmet medical need. Our
research and development pipeline of new investigational drugs includes
potential therapies for oncology and immunology. We leverage our proprietary and
proven chemistry platform to discover and design new drug candidates. These drug
candidates utilize our advanced polymer conjugate technology platforms, which
are designed to enable the development of new molecular entities that target
known mechanisms of action. We continue to make significant investments in new
drug discovery and advancing our pipeline of drug candidates as we believe that
this is the best strategy to build long-term stockholder value.

In oncology, we focus on developing medicines in immuno-oncology (I-O), which is
a therapeutic approach based on targeting biological pathways that stimulate and
sustain the body's immune response in order to fight cancer. In the I-O area, we
executed a broad clinical development program to develop bempegaldesleukin
(formerly NKTR-214) in combination with Opdivo® (nivolumab) in collaboration
with Bristol-Myers Squibb Company (BMS) under our Strategic Collaboration
Agreement. We also conducted independent development work evaluating
bempegaldesleukin in combination with other checkpoint inhibitors and agents
with potential complementary mechanisms of action, including studies evaluating
bempegaldesleukin combination with Keytruda® (pembrolizumab). In April 2022, we
and BMS jointly announced that the companies would be ending the global clinical
development program for bempegaldesleukin in combination with Opdivo® and
discontinue all ongoing studies in our collaboration with BMS. We also decided
to discontinue all studies of bempegaldesleukin in combination with Keytruda®,
as well as our studies of NKTR-262, which was being evaluated in combination
with bempegaldesleukin.

In April 2022, we announced new strategic reorganization and cost restructuring
plans (together, the Restructuring Plan) focused on prioritizing key research
and development efforts that will be most impactful to the Company's future,
including our NKTR-255 and rezpegaldesleukin (previously referred to as
NKTR-358) programs and several core research programs.

NKTR-255 is a biologic that targets the IL-15 pathway in order to activate the
body's innate and adaptive immunity. Activation of the IL-15 pathway enhances
the survival and function of natural killer (NK) cells and induces survival of
both effector and CD8+ memory T cells. Recombinant human IL-15 is rapidly
cleared from the body and must be administered frequently and in high doses
limiting its utility due to toxicity. Through optimal engagement of the IL-15
receptor complex, NKTR-255 is designed to enhance functional NK cell populations
and formation of long-term immunological memory, which may lead to sustained and
durable anti-tumor immune response. Preclinical findings suggest NKTR-255 has
the potential to synergistically combine with antibody-dependent cellular
cytotoxicity molecules as well as to enhance CAR-T therapies. We have initiated
a Phase 1 dose escalation and expansion clinical study of NKTR-255 in adults
with relapsed or refractory non-Hodgkin lymphoma or multiple myeloma, as well as
a Phase 1/2 clinical study of NKTR-255 in patients with relapsed or refractory
head and neck squamous cell carcinoma or colorectal cancer. We are continuing
our oncology clinical collaboration with Merck KGaA and Pfizer Inc. to evaluate
the maintenance regimen of NKTR-255 in combination with avelumab, a PD-L1
inhibitor, in patients with locally advanced or metastatic urothelial carcinoma
in the Phase II JAVELIN Bladder Medley study. We are also designing a
Nektar-sponsored Phase 2/3 study to combine NKTR-255 with approved autologous
CAR-T therapies in relapsed/refractory large B-cell lymphoma, to be initiated in
the first quarter of 2023.

In immunology, we recognize that a large number of diseases and conditions are
caused by an imbalance in the body's immune system. Pharmaceutical agents
designed to restore balance to the immune system can be used to help patients
suffering from immunology-based conditions, such as autoimmune diseases and
inflammatory diseases. Our drug candidate rezpegaldesleukin is being developed
as a once or twice monthly self-administered injection for a number of
autoimmune diseases and inflammatory diseasesis, and is designed to optimally
target the IL-2 receptor complex in order to stimulate proliferation and growth
of regulatory T cells. In 2017, we entered into a worldwide license agreement
with Eli Lilly and Company (Lilly) to develop and commercialize
rezpegaldesleukin, pursuant to which we received an initial payment of $150.0
million and are eligible for up to an additional $250.0 million for development
and regulatory milestones. We have completed our responsibilities for Phase 1
clinical development and certain drug product development and supply activities.
We also share Phase 2 development costs with Lilly, with Lilly responsible for
75% and Nektar responsible for 25% of these costs. Lilly is responsible for the
costs of Phase 3 development, but we retain the option to contribute up to 25%
of the costs of Phase 3 development on an indication-by-indication basis in
order for us to achieve the maximum royalty level under the Lilly Agreement, and
further, if approved, we will
                                       23

have the opportunity to receive a royalty rate up to the low twenties percent
based upon our Phase 3 development cost contribution and the level of annual
global product sales.

We have completed a Phase 1 dose-finding trial of rezpegaldesleukin to evaluate
single-ascending doses of rezpegaldesleukin in approximately 100 healthy
patients. We also completed treatment of a Phase 1 multiple-ascending dose trial
to evaluate rezpegaldesleukin in patients with systemic lupus erythematosus
(SLE). Lilly is conducting two Phase 1b studies in patients with psoriasis and
atopic dermatitis, and based on positive interim Phase 1b results in atopic
dermatitis announced in December 2021, Lilly is planning to initiate a Phase 2
study in atopic dermatitis. Lilly also initiated a Phase 2 study in SLE in
October 2020 and a Phase 2 study in ulcerative colitis in March 2021. In April
2022, we announced that Lilly had informed us that an interim analysis in the
Phase 2 study in ulcerative colitis led to the discontinuation of further
development in this indication. Lilly also plans to initiate another Phase 2
study in another immune-mediated disease to potentially start in 2023.

We have historically derived all of our revenue and substantial amounts of
operating capital from our collaboration agreements. In addition to our
collaborations with BMS and Lilly, we have received upfront and milestone
payments under a number of other previous collaboration agreements, several of
which have resulted in approved drugs, for which we may continue to manufacture
the polymer reagents used in the production of the drug products and may be
entitled to royalties for net sales of these approved drugs. As of December 31,
2020, however, we have sold the majority of our rights to receive royalties
under these arrangements, including:

•2012 Purchase and Sale Agreement: In 2012, we sold all of our rights to receive
royalties from CIMZIA® (for the treatment of Crohn's disease and other
autoimmune indications) and MIRCERA® (for the treatment of anemia associated
with chronic kidney disease) under our collaborations with UCB Pharma and F.
Hoffmann-La Roche Ltd, respectively, to RPI Finance Trust (RPI), an affiliate of
Royalty Pharma for $124.0 million.

•2020 Purchase and Sale Agreement: In December 2020, we sold our rights, subject
to a cap, to receive royalties from MOVANTIK® / MOVENTIG® (for the treatment of
opioid-induced constipation), ADYNOVATE® / ADYNOVI® (a half-life extension
product of Factor VIII) and other hemophilia products, under our arrangements
with AstraZeneca AB, Baxalta, Inc. (a wholly owned-subsidiary of Takeda
Pharmaceutical Company Ltd.), and Novo Nordisk A/S, respectively, for $150.0
million to entities managed by HealthCare Royalty Management (HCR) under a
capped sale arrangement, such that all future royalties return to Nektar if HCR
receives $210.0 million in royalties by December 31, 2025 (the 2025 Threshold)
or $240.0 million if the 2025 Threshold is not met.

While in the near-term we continue to expect to generate substantially all of
our revenue from collaboration arrangements, our long-term plan is to generate
significant commercial revenue from proprietary products. Over the next several
years, we plan to continue to make significant investments to advance our early
drug candidate pipeline. We have several drug candidates in earlier stage
clinical development or are being explored in research and that we are preparing
to advance into clinical trials in future years. We are cultivating several
research programs, including a collaboration with Biolojic Design to develop a
unique bivalent antibody targeting TNFR2 and our NKTR-288 research program.
NKTR-288 is a PEG conjugate of the protein interferon gamma that is designed
utilizing a site-specific conjugation approach to modify binding of interferon
gamma with one of its substrates and to optimize the pharmacodynamic duration of
interferon gamma signaling. NKTR-288 has potential applications in a number of
therapeutic indications in oncology and other infectious diseases. We believe
that our substantial investment in research and development has the potential to
create significant value if one or more of our drug candidates demonstrates
positive clinical results, receives regulatory approval in one or more major
markets and achieves commercial success.

Our business is subject to significant risks, including the risks inherent in
our development efforts, the results of our clinical trials, our dependence on
the marketing efforts by our collaboration partners, uncertainties associated
with obtaining and enforcing patents, the lengthy and expensive regulatory
approval process and competition from other products. Drug research and
development is an inherently uncertain process with a high risk of failure at
every stage prior to approval. The timing and outcome of clinical trial results
are extremely difficult to predict. Clinical development successes and failures
can have a disproportionately positive or negative impact on our scientific and
medical prospects, financial condition and prospects, results of operations and
market opportunities. For a discussion of these and some of the other key risks
and uncertainties affecting our business, see Item 1A "Risk Factors."

Effects of the COVID-19 Pandemic



We continue to actively monitor the ongoing COVID-19 pandemic and applicable
government recommendations in light of new developments. Currently, our
operations in research, manufacturing and maintenance that occur within our
facilities are continuing in accordance with applicable guidelines and orders.
Across all our locations, we have instituted a temporary work from home policy
for office personnel who do not need to work on site to maintain productivity
and we allow employees to voluntarily return to work on site with appropriate
health and safety measures. We believe that the safety measures we are taking
and instructing our contractors to take in response to the COVID-19 pandemic
meet or exceed the guidance and requirements
                                       24

issued from government and public health officials. We also continue to monitor
our supply chains for any disruptions or constraints caused by the COVID-19
pandemic. To date, we have not experienced any significant impacts on our
supply, but ongoing global shortages in labor, raw materials and equipment could
limit our ability to manufacture our products or to supply drug candidates for
our clinical trials, or delay our research and development efforts.

We and our partners are currently engaged in the clinical testing of our drug
candidates and the COVID-19 pandemic introduces challenges to our clinical
development programs which are central to our business. Nektar's Phase 1
clinical study of NKTR-255 in patients with relapsed/refractory hematologic
malignancies has enrolled slower than anticipated due to the challenges caused
by the COVID-19 pandemic. While we are not currently aware of significant delays
by our partners and collaborators caused by the COVID-19 pandemic on clinical
trials involving our drug candidates, any current assessments of the effects of
the COVID-19 pandemic on our clinical programs are difficult to predict and
subject to change and, with regard to individual clinical trial sites within
these studies, will likely vary by the geographic region in which they are
located.

We cannot predict what the overall impact the COVID-19 pandemic will be on our business and it could potentially adversely affect our business, financial condition, operations and prospects.



With respect to financing our near-term business needs, as set forth below in
"Key Developments and Trends in Liquidity and Capital Resources," we estimate we
have working capital to fund our current business plans through at least the
next twelve months.

Key Developments and Trends in Liquidity and Capital Resources



We estimate that we have working capital to fund our current business plans for
at least the next twelve months from the date of filing. At September 30, 2022,
we had approximately $546.4 million in cash and investments in marketable
securities.

Our revenue is derived from our collaboration agreements, under which we may
receive product sales revenue, royalties, and license fees, as well as
development and sales milestones and other contingent payments. We recognize
revenue when we transfer promised goods or services to our collaboration
partners. The amount of upfront fees received under our license and
collaboration agreements allocated to continuing obligations, such as
development or manufacturing and supply commitments, is generally recognized as
we deliver products or provide development services. As a result, there may be
significant variations in the timing of receipt of cash payments and our
recognition of revenue. We make our best estimate of the timing and amount of
                                       25

products and services expected to be required to fulfill our performance obligations. Given the uncertainties in research and development collaborations, significant judgment is required to make these estimates.

Product Sales

Product sales include predominantly fixed price manufacturing and supply agreements with our collaboration partners and are the result of firm purchase orders from those partners. The timing of shipments is based solely on the demand and requirements of our collaboration partners and is not ratable throughout the year.



Product sales decreased for the nine months ended September 30, 2022 as compared
to the nine months ended September 30, 2021 primarily due to a decrease in
product demand from our collaboration partners. We expect product sales for the
full year of 2022 to be marginally lower than 2021.

Non-cash Royalty Revenue Related to Sales of Future Royalties

For a discussion of our Non-cash royalty revenue, please see our discussion below in "Non-Cash Royalty Revenue and Non-Cash Interest Expense."

License, Collaboration and Other Revenue



License, collaboration and other revenue includes the recognition of upfront
payments, milestone and other contingent payments received in connection with
our license and collaboration agreements and certain research and development
activities. The level of license, collaboration and other revenue depends in
part upon the estimated recognition period of the upfront payments allocated to
continuing performance obligations, the achievement of milestones and other
contingent events, the continuation of existing collaborations, the amount of
research and development work, and entering into new collaboration agreements,
if any. During the nine months ended September 30, 2022, we recognized $1.5
million for a license agreement, under which we are entitled to no further
consideration. As a result of the recognition of this revenue in the nine months
ended September 30, 2022, we expect license, collaboration and other revenue for
2022 to increase compared to 2021.

The timing and future success of our drug development programs and those of our
collaboration partners are subject to a number of risks and uncertainties. See
Item 1A. Risk Factors for a discussion of the risks associated with the complex
nature of our collaboration agreements.

Our strategy is to manufacture and supply polymer reagents to support our
proprietary drug candidates or our third-party collaborators where we have a
strategic development and commercialization relationship or where we derive
substantial economic benefit. We have elected to only enter into and maintain
those manufacturing relationships associated with long-term collaboration
agreements which include multiple sources of revenue, which we view holistically
and in aggregate. We have a predominantly fixed cost base associated with our
manufacturing activities. As a result, our product gross profit and margin are
significantly impacted by the mix and volume of products sold in each period.

Our product gross margin improved from the three and nine months ended
September 30, 2021 to the three and nine months ended September 30, 2022 due to
the mix of manufacturing orders from our customers. Product gross margin was
negative for several of these periods. We have a manufacturing arrangement with
a partner that includes a fixed price which is less than the fully burdened
manufacturing cost for the reagent, and we expect this situation to continue
with this partner in future years. In addition to product sales to this partner,
we also receive royalty revenue from this collaboration. In the three and nine
months ended September 30, 2022 and 2021, the royalty revenue from this
collaboration exceeded the related negative gross profit for this customer.

We expect product gross margin to continue to fluctuate in future periods depending on the level and mix of manufacturing orders from our customers. We expect product gross profit to be negative in 2022 as a result of the collaborative arrangement described above.

Research and development expense consists primarily of clinical study costs,
contract manufacturing costs, direct costs of outside research, materials,
supplies, licenses and fees as well as personnel costs (including salaries,
benefits, and stock-based compensation). Research and development expense also
includes certain overhead allocations consisting of support and
facilities-related costs. Where we perform research and development activities
under a joint development collaboration, such as our collaboration with BMS, we
record the expense reimbursement from our partners as a reduction to research
and development expense, and we record our share of our partners' expenses as an
increase to research and development expense. Under the BMS Collaboration
Agreement, BMS generally bears 67.5% of development costs for bempegaldesleukin
in combination with Opdivo® and 35% of costs for manufacturing
bempegaldesleukin.

As discussed in Note 1, BMS and we have decided to discontinue development of
bempegaldesleukin in combination with Opdivo® and will wind down the various
clinical trials under the BMS Collaboration Agreement, and we have also decided
to discontinue all other development of bempegaldesleukin. The cost sharing
under the BMS Collaboration Agreement remains unchanged. Additionally, as
discussed in Note 8 to our Condensed Consolidated Financial Statements, we have
also implemented the Restructuring Plan to reduce our workforce by approximately
70%. As a result, beginning in the three months ended June 30, 2022, we report
clinical trial expense, other third-party costs and employee costs for the
bempegaldesleukin program, net of the reimbursement from BMS, within
Restructuring, impairment and other costs of terminated program in our Condensed
Consolidated Statement of Operations. Because we no longer report these expenses
in research and development expense, research and development expense decreased
significantly for the three and nine months ended September 30, 2022 as compared
to the three and nine months ended September 30, 2021, respectively, and we
expect this to continue for the remainder of 2022 as compared to 2021. During
the nine months ended September 30, 2022, we recorded $24.9 million as a
reduction of research and development expense for the net reimbursement from
BMS, reflecting the reimbursement we recorded in the three months ended March
31, 2022. For the three and nine months ended September 30, 2021, we recorded
$24.3 million and $76.5 million, respectively, as a reduction of research and
development expense for the net reimbursement from BMS. Please see our
discussion below in Restructuring, impairment and other costs of terminated
program for additional information.

We incurred research and development expense in the three and nine months ended
September 30, 2022 and September 30, 2021 for development costs and
manufacturing activities for NKTR-255 and development costs for
rezpegaldesleukin as Lilly conducts its Phase 1B and Phase 2 studies, for which
we are responsible for 25% of costs and Lilly is responsible for 75% of costs,
and we will continue to incur these costs as the development of NKTR-255 and
rezpegaldesleukin continues.

The timing and amount of our future clinical trial expenses will vary significantly based upon our evaluation of ongoing clinical results and the structure, timing, and scope of additional clinical development programs and potential clinical collaboration partnerships (if any) for these programs.

In addition to our drug candidates that we plan to evaluate in clinical
development during 2022 and beyond, we believe it is vitally important to
continue our substantial investment in a pipeline of new drug candidates to
continue to build the value of our drug candidate pipeline and our business. Our
discovery research organization is identifying new drug candidates across a wide
range of molecule classes, including small molecules and large proteins,
peptides and antibodies, across multiple therapeutic areas. We also plan from
time to time to evaluate opportunities to in-license potential drug candidates
from third parties to add to our drug discovery and development pipeline. We
plan to continue to advance our most promising early research drug candidates
into preclinical development with the objective to advance these early stage
research programs to human clinical studies over the next several years.

Our expenditures on current and future preclinical and clinical development
programs are subject to numerous uncertainties in timing and cost to completion.
In order to advance our drug candidates through clinical development, each drug
candidate must be tested in numerous preclinical safety, toxicology and efficacy
studies. We then conduct clinical studies for our drug candidates that take
several years to complete. The cost and time required to complete clinical
trials may vary significantly over the life of a clinical development program as
a result of a variety of factors, including but not limited to:

•the number of patients required for a given clinical study design;

•the length of time required to enroll clinical study participants;

•the number and location of sites included in the clinical studies;

•the clinical study designs required by the health authorities (i.e. primary and secondary endpoints as well as the size of the study population needed to demonstrate efficacy and safety outcomes);

•the potential for changing standards of care for the target patient population;

•the competition for patient recruitment from competitive drug candidates being studied in the same clinical setting;

•the costs of producing supplies of the drug candidates needed for clinical trials and regulatory submissions;

•the safety and efficacy profile of the drug candidate;

•the use of clinical research organizations to assist with the management of the trials; and

•the costs and timing of, and the ability to secure, approvals from government health authorities.



Furthermore, our strategy includes the potential of entering into collaborations
with third parties to participate in the development and commercialization of
some of our drug candidates such as the collaboration that we have already
completed for rezpegaldesleukin, or clinical collaborations where we would share
costs and operational responsibility with a partner. In certain situations, the
clinical development program and process for a drug candidate and the estimated
completion date will largely be under the control of that third party and not
under our control. We cannot forecast with any degree of certainty which of our
drug candidates will be subject to future collaborations or how such
arrangements would affect our development plans or capital requirements.

General and administrative expense includes the cost of administrative staffing,
commercial, finance and legal activities. As discussed in Note 8 to our
Condensed Consolidated Financial Statements, we have implemented a Restructuring
Plan to reduce our workforce by approximately 70%. As a result of our
Restructuring Plan, the commercial organization was eliminated and all other
bempegaldesleukin-related commercialization activities ceased. Accordingly,
general and administrative expense decreased for the three and nine months ended
September 30, 2022 compared with the three and nine months ended September 30,
2021,

As discussed in Note 8 to our Condensed Consolidated Financial Statements,
following the announcements in March and April 2022 that our registrational
trials in bempegaldesleukin failed to meet their primary endpoints, on April 25,
2022, we announced strategic reorganization and cost restructuring plans
(together, the Restructuring Plan) to prioritize key Phase 2 development
programs, to advance our early stage research pipeline and to reduce our
workforce by approximately 70% from approximately 735 to approximately 225
employees. In connection with these events, we reported the following costs in
Restructuring, impairment and other costs of terminated program:

•Clinical trial expense, other third-party costs and employee costs for the wind down of the bempegaldesleukin program, net of the reimbursement from BMS;

•Severance and related benefit costs pursuant to the Restructuring Plan;



•Impairment of right-of-use assets and property, plant and equipment resulting
from the Restructuring Plan, primarily reflecting excess office and laboratory
leased spaces in San Francisco, CA; and

•Contract termination and other costs associated with these plans.

For the three and nine months ended September 30, 2022, we recorded reductions
of expense of $8.3 million and $16.7 million, respectively, for the net
reimbursement from BMS, primarily for clinical trial expense, other third-party
and employee costs for the wind down of the bempegaldesleukin program. We will
continue to recognize expenses in future periods for the winddown of the
bempegaldesleukin program and related costs, of which we expect to recognize a
significant portion in 2022. The ultimate amount of expense will be affected by
the timing to complete the full wind down of the clinical trials run by BMS and
us and whether or not we are able to enter into subleases and, if we do enter
into subleases, the economic terms of those subleases. We will revise our
estimates for the costs to wind down these studies for the bempegaldesleukin
program, the amount of severance and benefits paid to employees, and our
assessment of impairment charges as new information becomes available to us in
future periods.

(1) Percentage change represents a reduction of the expense or change to income.




As discussed in Note 4 to our Condensed Consolidated Financial Statements, we
remeasured the development derivative liability under our co-development
agreement with SFJ to fair value at each reporting date. As discussed in Note 4,
as of March 31, 2022, due to the results of the metastatic melanoma trial, we
concluded that it was remote that SFJ and we would continue the clinical trial
in head and neck cancer. Accordingly, we reduced the liability to $0 as of March
31, 2022 and recognized a corresponding gain in the change in fair value of
development derivative liability. As a result of the decision to discontinue the
clinical trial in head and neck cancer, we do not expect to record any future
significant adjustments for the change in fair value.

The expense recorded for the change in fair value for the three and nine months
ended September 30, 2021 primarily reflected the accretion of our obligation to
potentially pay Success Payments to SFJ using our imputed borrowing rate.

As discussed in Note 5 to our Condensed Consolidated Financial Statements, we
recognize non-cash royalty revenue for the 2012 Purchase and Sale Agreement and
the 2020 Purchase and Sale Agreement.

Non-cash royalty revenue decreased for the three and nine months ended
September 30, 2022 as compared to the three and nine months ended September 30,
2021. Non-cash interest expense decreased significantly for the three and nine
months ended September 30, 2022 as compared to the three and nine months ended
September 30, 2021

2012 Purchase and Sale Agreement



The decrease in the non-cash interest expense in 2022 resulted from the decrease
in the interest rate from 48% in the three and nine months ended September 30,
2021 to 16% for the three and nine months ended September 30, 2022 as a result
of the revaluation of the liability, which we recognized in the three months
ended December 31, 2021.

To resolve UCB's challenges to our patents and their resulting obligation to pay
us royalties on net sales of CIMZIA® which we had sold to RPI, RPI and UCB
negotiated a reduction in the royalty term and decreased royalty rates over the
remaining term, which was implemented through the Settlement Agreement between
UCB and us. As a result of accounting for the Settlement Agreement as a debt
modification during the three months ended December 31, 2021, we remeasured the
liability to fair value using a discount rate of 16%. The Settlement Agreement
and revaluation do not affect our cash flows, and the net income statement
effect over the term of 2012 Purchase and Sale Agreement remains unchanged.

Over the term of this arrangement, the net proceeds of the transaction of $114.0
million, consisting of the original proceeds of $124.0 million, net of $10.0
million in payments from us to RPI, is amortized as the difference between the
non-cash royalty revenue and the sum of the non-cash interest expense and the
loss on the revaluation of the liability. To date, we have amortized $51.4
million of the net proceeds. We periodically assess future non-cash royalty
revenues, and we may adjust the prospective effective interest rate based on our
best estimates of future non-cash royalty revenue such that future non-cash
interest expense will amortize the remaining $62.6 million of the net proceeds,
since RPI receives all of the benefits of the increases in future royalties.
There are a number of factors that could materially affect our estimated
interest rate, in particular, the amount and timing of royalty payments from
future net sales of CIMZIA® and MIRCERA®. As a result, future interest rates
could differ significantly, and we will adjust any such change in our estimated
interest rate prospectively.

2020 Purchase and Sale Agreement



To date, we have amortized $44.7 million of the proceeds. We periodically assess
future non-cash royalty revenues, and we may adjust the prospective effective
interest rate based on our best estimates of future non-cash royalty revenue
such that future non-cash interest expense will amortize the remaining $105.3
million. Our current estimate of the imputed interest rate
                                       31

reflects that our estimates of sales of MOVANTIK®, ADYNOVATE® and REBINYN® will
result in meeting the 2025 Threshold. Because the 2025 Threshold of $210.0
million and the increase in the threshold to $240.0 million (if the 2025
Threshold is not timely achieved) limit the amount of royalties payable to HCR,
the potential for the implicit interest rate to vary is more limited. Instead,
we will receive the benefit of net sales if they exceed the threshold, but do
not bear risk of loss or payments to HCR if royalties are less than expected.

Interest income and other income (expense) increased for the three and nine months ended September 30, 2022 as compared to the three months ended September 30, 2021 due to increases in interest rates. We expect that our interest income and other income (expense), net will increase for 2022 compared to 2021 for the same reason.

Liquidity and Capital Resources



We have financed our operations primarily through revenue from upfront and
milestone payments under our strategic collaboration agreements, royalties and
product sales, as well as public and private placements of debt and equity
securities. As of September 30, 2022, we had approximately $546.4 million in
cash and investments in marketable securities.

We estimate that we have working capital to fund our current business plans for
at least the next twelve months from the date of filing, which includes the
payments for the winddown of the bempegaldesleukin program, as further disclosed
in Note 8 to our Condensed Consolidated Financial Statements.

We expect the clinical development of our drug candidates, including
rezpegaldesleukin and NKTR-255, will continue to require significant investment
to continue to advance in clinical development with the objective of obtaining
regulatory approval or entering into one or more collaboration partnerships. In
the past, we have received a number of significant payments from collaboration
agreements and other significant transactions, including $1.9 billion in total
consideration received under our arrangement with BMS, development cost
reimbursements from BMS, and a $150.0 million upfront payment from Lilly for our
collaboration agreement for rezpegaldesleukin. In the future, we have the
opportunity to receive up to $250.0 million in milestone payments under our
collaboration with Lilly.

Our current business is subject to significant uncertainties and risks as a
result of, among other factors, clinical and regulatory outcomes for
rezpegaldesleukin and NKTR-255, the sales levels for those products (for both
wholly owned products such as NKTR-255 and for licensed products such as
rezpegaldesleukin for which we are entitled to royalties), if and when they are
approved, whether, when and on what terms we are able to enter into new
collaboration transactions, expenses being higher than anticipated, unplanned
expenses, cash receipts being lower than anticipated, and the need to satisfy
contingent liabilities, including litigation matters and indemnification
obligations.

We have no credit facility or any other sources of committed capital. The
availability and terms of various financing alternatives, if required in the
future, substantially depend on many factors including the success or failure of
drug development programs in our pipeline. The availability and terms of
financing alternatives and any future significant payments from existing or new
collaborations depend on the positive outcome of ongoing or planned clinical
studies, whether we or our partners are successful in obtaining regulatory
authority approvals in major markets, and if approved, the commercial success of
these drugs, as well as general capital market conditions. We may pursue various
financing alternatives to fund the expansion of our business as appropriate.

In the short term, we do not anticipate that the effects of the COVID-19
pandemic will have a material effect on our results of operations or financial
position since we do not generate significant cash flows from recurring revenues
and our revenues are generally less affected by regulatory restrictions and
guidelines that have been implemented in response to the pandemic. However, if
delays caused by the COVID-19 pandemic in commencing and enrolling patients in
our clinical trials or
                                       32

those run by our partners result in a delay in completing these trials, our or
our partner's ability to file for regulatory approval and commercialize these
products (if approved) and receive associated milestone payments may also be
delayed.

Due to the potential for adverse developments in the credit markets, we may
experience reduced liquidity with respect to some of our investments in
marketable securities. These investments are generally held to maturity, which,
in accordance with our investment policy, is less than two years. However, if
the need arises to liquidate such securities before maturity, we may experience
losses on liquidation. To date we have not experienced any liquidity issues with
respect to these securities. We believe that, even allowing for potential
liquidity issues with respect to these securities and the effect of various
conditions on the financial markets, our remaining cash and investments in
marketable securities will be sufficient to meet our anticipated cash needs for
at least the next twelve months.

We currently have an effective shelf registration statement on Form S-3 (the
2021 Shelf Registration Statement) on file with the Securities and Exchange
Commission, which expires in March 2024. The 2021 Shelf Registration Statement
currently permits the offering, issuance and sale by us of up to an aggregate
offering price of $300.0 million of common stock, preferred stock, debt
securities and warrants in one or more offerings and in any combination, all of
which may be offered, issued and sold in "at-the-market" sales pursuant to an
equity distribution agreement with Cowen and Company, LLC (the Equity
Distribution Agreement). No securities have been sold under the 2021 Shelf
Registration Statement or the Equity Distribution Agreement.

Cash flows from operating activities

Cash flows used in operating activities for the nine months ended September 30, 2022 and 2021 totaled $246.3 million and $261.1 million, respectively.

We expect that cash flows used in operating activities, excluding upfront, milestone and other contingent payments received, if any, will decrease for 2022 as compared to 2021 as a result of the wind down of the bempegaldesleukin program and the various cost restructuring activities described above.

Cash flows from investing activities



During the nine months ended September 30, 2022 and 2021, the maturities and
sales of our investments, net of purchases, totaled $331.0 million and
$91.7 million, respectively, which we used to fund our operations. Our
maturities and sales of investments, net of purchases was lower during the nine
months ended September 30, 2021 as compared to the nine months ended September
30, 2022, because we purchased securities in early 2021, utilizing the $150.0
million in proceeds from the 2020 Purchase and Sale Agreement that were included
in cash equivalents at December 31, 2020.

We paid $5.2 million and $9.1 million for the purchase or construction of property, plant and equipment in the nine months ended September 30, 2022 and 2021, respectively.

Cash flows from financing activities



We received proceeds from issuance of common stock related to our employee
option and stock purchase plans of $0.7 million and $31.4 million in the nine
months ended September 30, 2022 and 2021, respectively. Additionally, during the
nine months ended September 30, 2022 and 2021, we received $0.8 million and $2.3
million, respectively, from SFJ pursuant to our co-development agreement.

Critical Accounting Policies and Estimates



The preparation and presentation of financial statements in conformity with
U.S. generally accepted accounting principles (GAAP) requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period.

We base our estimates on historical experience and on various other assumptions
that we believe to be reasonable under the circumstances, the results of which
form our basis for making judgments about the carrying value of assets and
liabilities that are not readily apparent from other sources. We evaluate our
estimates on an ongoing basis. Actual results may differ from those estimates
under different assumptions or conditions. See Note 1 and Note 8 to our
Condensed Consolidated Financial Statements for our accounting policies and
estimates related to the severance and benefits and the impairment of
right-of-use assets and property, plant and equipment. Other than these
accounting policies and estimates, there have been no material changes to our
critical accounting policies and estimates discussed in our Annual Report on
Form 10-K for the fiscal year ended December 31, 2021.
