Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization | Organization Nektar Therapeutics (Nektar, we) is 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). We are conducting Phase 2b trials in rezpegaldesleukin in patients with moderate-to-severe atopic dermatitis which we initiated in October 2023 (the Phase 2b REZOLVE-AD trial) and in patients with severe-to-very severe alopecia areata which we initiated in March 2024 (the Phase 2b REZOLVE-AA trial). On February 24, 2025, we announced that we had entered into a collaboration agreement with TrialNet to evaluate rezpegaldesleukin in patients with new onset stage 3 type 1 diabetes mellitus in a Phase 2 study. TrialNet will conduct the study with funding from the National Institutes of Health, primarily through the Special Statutory Funding Program for Type 1 Diabetes through the National Institute of Diabetes and Digestive and Kidney Diseases. Nektar will supply rezpegaldesleukin for the study and will retain all rights to the rezpegaldesleukin program under the collaboration. On June 24, 2025, we announced data from the 16-week induction period of the ongoing Phase 2b REZOLVE-AD trial being conducted in 393 patients. 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 June 30, 2025, we had approximately $175.9 million in cash and investments in marketable securities. As we continue our research and development activities, we will need additional cash to fund our operations. Accordingly, we may enter into new collaboration agreements or other similar transactions, and we may also seek financing transactions, which may include dilutive equity-based financings, such as an offering of our common stock. There can be no assurance that any additional collaboration agreements or financings will be available to us on commercially reasonable terms. We believe we have sufficient cash and investments in marketable securities to fund operations through at least the next twelve months from the date of the filing of these financial statements. We filed a shelf registration statement on Form S-3 and a related prospectus (the Shelf Registration Statement) that was declared effective by the Securities and Exchange Commission (the SEC) on April 1, 2025. Pursuant to the Shelf Registration Statement, we may offer and sell common stock, preferred stock, debt securities, warrants and or units having an aggregate public offering price of up to $300.0 million. In connection with the filing of the Shelf Registration Statement, we also entered into an equity distribution agreement (the Sales Agreement) with Piper Sandler & Co. and BTIG, LLC, relating to the sale of our common stock having an aggregate offering price of up to $75.0 million. We have agreed to pay Piper Sandler & Co. and BTIG, LLC a commission equal to 3.0% of the gross sales price of all common stock sold through them as sales agents. As of June 30, 2025, no shares have been issued under the Shelf Registration Statement or the Sales Agreement. On July 2, 2025, pursuant to the Shelf Registration Statement, we completed the sale and issuance of 4,893,618 shares of our common stock in an underwritten public offering (the 2025 Offering) at a price of $23.50 per share. The net proceeds to the Company from the 2025 Offering totaled approximately $107.5 million, after deducting underwriting discounts and commissions and offering costs of approximately $7.5 million. See Note 6 for additional information. Sale of Manufacturing Facility On December 2, 2024, we completed the sale of our manufacturing facility located in Huntsville, Alabama (the Facility) and certain other manufacturing assets related thereto, including the assignment of our existing manufacturing and supply obligations, to Gannet BioChem, an affiliate of Ampersand Management LLC d/b/a Ampersand Capital Partners (Ampersand), via an Asset Purchase Agreement (the APA), for consideration of $64.7 million in cash, net of transaction costs, and an approximate 20% equity ownership at the time of close in Gannet BioChem. See Note 4 for additional information. As a result of the sale of the Facility, we no longer recognize product sales or cost of goods sold.
Sale of Manufacturing Facility | Sale of Manufacturing Facility On December 2, 2024, we completed the sale of our manufacturing facility located in Huntsville, Alabama (the Facility) and certain other manufacturing assets related thereto, including the assignment of our existing manufacturing and supply obligations, to Gannet BioChem, an affiliate of Ampersand Management LLC d/b/a Ampersand Capital Partners (Ampersand), via an Asset Purchase Agreement (the APA), for consideration of $64.7 million in cash, net of transaction costs, and an approximate 20% equity ownership at the time of close in Gannet BioChem. See Note 4 for additional information. As a result of the sale of the Facility, we no longer recognize product sales or cost of goods sold.
Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation We have prepared our Condensed Consolidated Financial Statements pursuant to U.S. generally accepted accounting principles (U.S. GAAP) and the rules and regulations of the 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. 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 include the financial position, results of operations and cash flows of our wholly-owned subsidiaries. In determining whether we are the primary beneficiary of a variable interest entity, we consider whether we have both the power to direct activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to that entity. We do not have any interests in any variable interest entities of which we are the primary beneficiary. We have eliminated all intercompany accounts and transactions in consolidation. 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 income (loss) in the stockholders’ equity (deficit) section of our Condensed Consolidated Balance Sheets. Our comprehensive loss consists of our net loss plus our foreign currency translation gains and losses (to the extent recognized in other comprehensive income (loss)) 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 and six months ended June 30, 2025 and 2024. We include translation gains and losses in accumulated other comprehensive income (loss) in the stockholders’ equity (deficit) section of our Condensed Consolidated Balance Sheets. However, if we have concluded that we have substantially liquidated the entity, such as for our subsidiary in India, we recognize subsequent translation gains and losses in other income (expense) in our Condensed Consolidated Statement of Operations. The accompanying Condensed Consolidated Financial Statements are unaudited. The Condensed Consolidated Balance Sheet data as of December 31, 2024 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, 2024 filed with the SEC on March 14, 2025. 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 | Use of Estimates The preparation of consolidated financial statements in conformity with U.S. 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.
Related Parties | Related Parties Transactions between related parties are considered to be related party transactions even though they may not be given accounting recognition. Accounting Standards Codification (ASC) 850, Related Party Disclosures (ASC 850) requires that transactions with related parties that would make a difference in decision making shall be disclosed so that users of the financial statements can evaluate their significance. See Note 4 regarding our related party transactions with Gannet BioChem.
Significant Concentrations | Significant Concentrations Our customers are primarily pharmaceutical and biotechnology companies with whom we have multi-year arrangements. Before the sale of the Facility, our accounts receivable balance primarily contained trade receivables from product sales. We have no t recorded provisions for credit losses for the three and six months ended June 30, 2025 and 2024. Accounts receivable at June 30, 2025 and December 31, 2024 are immaterial due to the sale of the Facility in December 2024. 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, our suppliers and contract manufacturers may rely on single sources of supply of one or more critical materials. As a result of the sale of the Facility, we are dependent on Gannet BioChem for the supply of the polyethylene glycol reagents (PEG reagents) used in the manufacture of rezpegaldesleukin and NKTR-255. 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.
Reverse Stock Split | Reverse Stock Split On June 6, 2025, we filed a Certificate of Amendment to the Certificate of Incorporation, or the Reverse Stock Split Amendment, to effect a reverse stock split of Nektar’s Common Stock at a ratio of one-for-fifteen, effective June 8, 2025. No fractional shares of common stock were issued as a result of the Reverse Stock Split. All share and per share figures in these financial statements have been adjusted to give retrospective effect to the Reverse Stock Split. See Note 6 for additional information.
Treasury Stock | 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 | Restructuring In April 2022 and April 2023, we announced certain restructuring plans (the 2022 Restructuring Plan and the 2023 Restructuring Plan, respectively), pursuant to which we terminated significant portions of our workforce and decided to sublease all of our leased premises in San Francisco, California, including our office space on Third St. (Third St. Facility) and our office and laboratory space on Mission Bay Blvd. South (Mission Bay Facility). 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 contract termination costs incurred when we cancel the contract in accordance with its terms, or for costs to be incurred over the remaining contract term without economic benefit to us at the cease-use date.
Long-Lived Asset Impairment | 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 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.
Income Taxes | Income Taxes On July 4, 2025, the budget reconciliation bill H.R. 1, known as the One Big Beautiful Bill (OBBB), was signed into law. The OBBB contains several changes to corporate taxation including modifications to capitalization of research and development expenses, limitations on deductions for interest expense and accelerated fixed asset depreciation. We are in the process of evaluating the OBBB’s impact on our financial statements.
Equity Method Investment | Equity Method Investment Our investment in Gannet BioChem is considered a variable interest entity for which we are not the primary beneficiary. We use the equity method of accounting to account for our investment in Gannet BioChem, which is an entity that we do not control, but have the ability to exert significant influence. Judgments regarding the level of influence over the equity method investment include consideration of key factors such as our ownership interest, representation on the board of directors or participation in policy-making decisions. Under the equity method of accounting, our investment in Gannet BioChem is initially recorded at fair value. The carrying value of the investment is subsequently adjusted based on our share of the net income or loss of the entity which we present as gain or loss from equity method investment in our Condensed Consolidated Statement of Operations. We record our share of the equity method investment’s results of operations on a three-month lag basis. Due to Ampersand’s right to receive a cumulative preferred dividend at a certain annual rate of return and return of capital before any distributions are made to us as further disclosed in Note 4, we record our gain or loss on our investment in Gannet BioChem under the hypothetical liquidation at book value (HLBV) method. The HLBV method is a balance sheet approach that calculates the change in the hypothetical amount Ampersand and we would be entitled to receive if Gannet BioChem were liquidated at book value at the end of each period, adjusted for any contributions made and distributions received during the period, as well as basis differences between the initial fair value of our investment in Gannet BioChem and our claim on the net assets of Gannet BioChem. Our maximum exposure to loss in Gannet BioChem is limited to the carrying value of our investment. We evaluate our equity method investment at the end of each reporting period to determine whether events or changes in business circumstances indicate that the carrying value of the investment may not be recoverable. This evaluation consists of several qualitative and quantitative factors that may include recent financial results, projected financial results and operating trends of the investees and other publicly available information that may affect the value of our investment.
Net Loss per Share | 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, as further disclosed in Note 4, 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 and six months ended June 30, 2025 and 2024, 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 June 30, |  |  | Six Months Ended June 30, |
|  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |
Potentially dilutive securities |  |  | 2,271,937 |  |  |  | 1,760,498 |  |  |  | 2,289,750 |  |  |  | 1,779,695 |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which will require incremental income tax disclosures on an annual basis for all public entities. The amendments require that public business entities disclose specific categories in the rate reconciliation and provide additional information for reconciling items meeting a quantitative threshold. The amendments also require disclosure of income taxes paid to be disaggregated by jurisdiction, and disclosure of income tax expense disaggregated by federal, state, and foreign. ASU 2023-09 is effective for annual reporting beginning with the fiscal year ending December 31, 2025. We are currently evaluating the incremental disclosures that will be required in our consolidated financial statements. In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, an accounting standard update that requires the Company to disclose more detailed information about the types of expenses (including employee compensation, depreciation, and amortization) included in each relevant income statement expense caption. In January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, to clarify the effective date of ASU 2024-03. The ASU is effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. We are currently evaluating the incremental disclosures that will be required in our consolidated financial statements.
