Organization and Summary of Significant Accounting Policies

Note 1 — Organization and Summary of Significant Accounting Policies

Organization

We are a clinical stage, research-based drug discovery biopharmaceutical company headquartered in San Francisco, California and incorporated in Delaware, focused on discovering and developing innovative medicines in the field of immunotherapy. Within this growing field, we direct our efforts toward creating new immunomodulatory agents that selectively induce, amplify, attenuate or prevent immune responses in order to achieve desired therapeutic outcomes. Our pipeline of clinical-stage and preclinical-stage immunomodulatory agents targets the treatment of autoimmune diseases (e.g. rezpegaldesleukin and NKTR-0165, respectively) and cancer (e.g. NKTR-255).

Our research and development activities have required significant ongoing investment to date and are expected to continue to require significant investment. As a result, we expect to continue to incur substantial losses and negative cash flows from operations in the future. We have financed our operations primarily through cash generated from licensing, collaboration and manufacturing agreements and financing transactions. As of March 31, 2024, we had approximately $326.0 million in cash and investments in marketable securities.

Financing Transactions

During the three months ended March 31, 2024, we entered into the following transactions:

•On February 12, 2024, for total cash consideration paid of $3.0 million, we repurchased from Bristol Myers Squibb Company (BMS) 8.3 million shares of Nektar's common stock that were previously sold to BMS, which we report as treasury stock on our Condensed Consolidated Balance Sheets. See Note 6 for additional information.

•On March 4, 2024, we entered into a Securities Purchase Agreement with TCG Crossover Fund II, L.P. (TCG), pursuant to which we issued a pre-funded warrant to TCG to purchase 25,000,000 shares of Nektar’s common stock for gross proceeds of $30.0 million (or a purchase price of $1.20 per share of common stock that can be issued upon exercise of the pre-funded warrant). See Note 5 for additional information.

•On March 4, 2024, for total cash consideration received of $15.0 million, we entered into an amendment (the Amendment) with entities managed by Healthcare Royalty Management, LLC (collectively, HCR) to remove the cap on royalties previously sold to HCR under a Purchase and Sale Agreement (the 2020 Purchase and Sale Agreement). See Note 3 for additional information.

Restructuring Plans

In April 2022, we announced the termination of the bempegaldesleukin program and a new strategic reorganization and cost restructuring plan (together, the 2022 Restructuring Plan), pursuant to which we completed an approximate 70% reduction of our workforce during 2022. We also decided to seek a sublease for certain of our leased premises in San Francisco, CA, including all of our office leased space on Third St. and portions of our office and laboratory space on Mission Bay Blvd. South.

In April 2023, we announced Eli Lilly and Company's (Lilly) decision to terminate our license agreement (the Lilly Agreement) for the development of rezpegaldesleukin, as well as a new strategic reprioritization and cost restructuring plan (the 2023 Restructuring Plan). Under the 2023 Restructuring Plan, we reduced our San Francisco-based workforce by approximately 60%. In addition, under the 2023 Restructuring Plan, we decided to seek a sublease for our remaining office and laboratory space on Mission Bay Blvd. South which we had not planned to sublease pursuant to the 2022 Restructuring Plan.

We have regained full rights to rezpegaldesleukin from Lilly, and we initiated a Phase 2b study of rezpegaldesleukin in patients with moderate-to-severe atopic dermatitis in October 2023 and a Phase 2b study of rezpegaldesleukin in patients with severe-to-very severe alopecia areata in March 2024. We will also explore other auto-immune indications for the development of rezpegaldesleukin.

We have incurred significant costs resulting from the 2022 and 2023 Restructuring Plans. See Note 7 for additional information on the effect on our Condensed Consolidated Financial Statements.

Basis of Presentation and Principles of Consolidation

Our Condensed Consolidated Financial Statements include the financial position, results of operations and cash flows of Nektar Therapeutics and our wholly-owned subsidiaries. We have eliminated all intercompany accounts and transactions in consolidation.

We prepared our Condensed Consolidated Financial Statements following the requirements of the Securities and Exchange Commission (SEC) for interim reporting. As permitted under those rules, we may condense or omit certain footnotes or other financial information that are normally required by U.S. generally accepted accounting principles (GAAP) for annual periods. In the opinion of management, these financial statements include all normal and recurring adjustments that we consider necessary for the fair presentation of our financial position and operating results.

Our Condensed Consolidated Financial Statements are denominated in U.S. dollars. Accordingly, changes in exchange rates between the applicable foreign currency and the U.S. dollar will affect the translation of each foreign subsidiary’s financial results into U.S. dollars for purposes of reporting our consolidated financial results. We include translation gains and losses in accumulated other comprehensive loss in the stockholders’ equity section of our Condensed Consolidated Balance Sheets.

Our comprehensive loss consists of our net loss plus our foreign currency translation gains and losses and unrealized gains and losses on available-for-sale securities. There were no significant reclassifications out of accumulated other comprehensive income (loss) to the statements of operations during the three months ended March 31, 2024 and 2023.

The accompanying Condensed Consolidated Financial Statements are unaudited. The Condensed Consolidated Balance Sheet data as of December 31, 2023 was derived from the audited consolidated financial statements which are included in our Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on March 5, 2024. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and the accompanying notes to those financial statements.

Revenue, expenses, assets, and liabilities can vary during each quarter of the year. The results and trends in these interim Condensed Consolidated Financial Statements are not necessarily indicative of the results to be expected for the full year or any other period.

Use of Estimates

The preparation of consolidated 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 consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Accounting estimates and assumptions are inherently uncertain.

Actual results could differ materially from those estimates and assumptions. As appropriate, we assess estimates each period, update them to reflect current information, and generally reflect any changes in estimates in the period first identified.

Significant Concentrations

Our customers are primarily pharmaceutical companies that are located in the U.S. and Europe and with whom we have multi-year arrangements. Our accounts receivable balance contains billed and unbilled trade receivables from product sales, milestones (to the extent that they have been achieved and are due from the counterparty), and other contingent payments, as well as reimbursable costs from collaborative research and development agreements. We generally do not require collateral from our

customers. We perform a regular review of our customers’ credit risk and payment histories, including payments made after period end. Historically, we have not experienced credit losses from our accounts receivable. We have not recorded reserves for credit losses for the three months ended March 31, 2024 and 2023, nor have recorded such an allowance as of March 31, 2024 or December 31, 2023.

We are dependent on our suppliers and contract manufacturers to provide raw materials and drugs of appropriate quality and reliability and to meet applicable contract and regulatory requirements. In certain cases, we rely on single sources of supply of one or more critical materials. Consequently, in the event that supplies are delayed or interrupted for any reason, our ability to develop and produce our drug candidates or our ability to meet our supply obligations could be significantly impaired, which could have a material adverse effect on our business, financial condition and results of operations.

For our available-for-sale securities, we have significant concentrations of issuers in the banking and financial services industries. While our investment policy requires that we only invest in highly-rated securities and limit our exposure to any single issuer, various factors may materially affect the financial condition of issuers. Additionally, pursuant to our investment policy, we may sell securities before maturity if the issuer’s credit rating has been downgraded below our minimum credit rating requirements, which may result in a loss on the sale. Accordingly, if various factors result in downgrades below our minimum credit rating requirements and if we decide to sell these securities, we may experience losses on such sales.

Treasury Stock

We record treasury stock activities under the cost method. Treasury stock is included in authorized and issued shares but excluded from outstanding shares. The re-issuance of treasury stock is accounted for on a first in, first-out basis and any differences between the cost of treasury stock and the re-issuance proceeds are charged or credited to additional paid-in capital.

Restructuring

We recognize restructuring charges related to reorganization plans that have been committed to by management when liabilities have been incurred. In connection with these activities, we record restructuring charges at fair value for:

•contractual or other employee termination benefits provided that the obligations result from services already rendered based on rights that vest or accumulated when the payment of benefits becomes probable and the amount can be reasonably estimated,

•one-time employee termination benefits on the communication date from management to the employees provided that management has committed to a plan of termination, the plan identifies the employees and their expected termination dates, the details of termination benefits are complete, and it is unlikely that changes to the plan will be made or the plan will be withdrawn,

•contract termination costs when we cancel the contract in accordance with its terms, and

•costs to be incurred over the remaining contract term without economic benefit to us at the cease-use date.

For one-time employee terminations benefits, we recognize the liability in full on the communication date when future services are not required or amortize the liability ratably over the service period, if required. The fair value of termination benefits reflects our estimates of expected utilization of certain Company-funded post-employment benefits.

See Note 7 for additional information on the severance expense that we recognized for employees terminated in connection with our reductions-in-force.

Impairment of Goodwill

Goodwill is assessed for impairment on an annual basis and whenever events and circumstances indicate that it may be impaired. Factors that may indicate potential impairment and trigger an impairment test include, but are not limited to, current economic, market and geopolitical conditions, including a significant, sustained decline in our stock price and market

capitalization compared to the net book value; an adverse change in legal factors, business climate or operational performance of the business; or significant changes in the ability of the reporting unit to generate positive cash flows for our strategic business objectives. If the carrying value of the reporting unit, including goodwill, exceeds the reporting unit’s fair value, we will recognize a goodwill impairment loss, and we will write down goodwill such that the carrying value of the reporting unit equals its fair value, provided that we cannot reduce goodwill below zero.

See Note 8 for additional information regarding the impairment charges we recorded during the three months ended March 31, 2023 in connection with our goodwill.

Long-Lived Asset Impairment

We assess the impairment of long-lived assets whenever events or changes in business circumstances indicate that the carrying amounts of the assets may not be fully recoverable. In the case of property, plant and equipment and right-of-use assets for our leases, we determine whether there has been an impairment by comparing the carrying value of the asset to the anticipated undiscounted net cash flows associated with the asset. If such cash flows are less than the carrying value, we write down the asset to its fair value, which may be measured as anticipated net cash flows associated with the asset, discounted at a rate that we believe a market participant would utilize to reflect the risks associated with the cash flows, such as credit risk.

See Note 7 for additional information regarding the impairment charges we recorded in connection with our leased facilities and certain property and equipment.

Net Loss per Share

For all periods presented in the Condensed Consolidated Statements of Operations, the net loss available to common stockholders is equal to the reported net loss. We calculate basic net loss per share based on the weighted-average number of common shares outstanding, including the pre-funded warrant, during the periods presented. Shares of common stock into which the pre-funded warrant may be exercised are considered outstanding for the purposes of computing basic net loss per share because the shares may be issued for little or no consideration, are fully vested and are exercisable after the original issuance date. For the three months ended March 31, 2024 and 2023, basic and diluted net loss per share are the same due to our net losses and the requirement to exclude potentially dilutive securities which would have an antidilutive effect on net loss per share. We excluded shares underlying the weighted average outstanding stock options, restricted stock units (RSUs) and performance stock units (PSUs), as follows (in thousands):

	Three Months Ended March 31,
	2024		2023
Potentially dilutive securities		26,973		22,798
