Nektar Therapeutics Reports Fourth Quarter and Full Year 2025 Financial Results
SAN FRANCISCO, March 12, 2026 /PRNewswire/ -- Nektar Therapeutics (NASDAQ:NKTR) today reported financial results for the fourth quarter ended December 31, 2025.
Cash and investments in marketable securities on December 31, 2025 were $245.8 million as compared to $269.1 million on December 31, 2024. Cash and investments at December 31, 2025 excludes net proceeds of approximately $432 million from the $460 million secondary offering completed by the Company in February 2026, and also excludes net proceeds of $44 million from sales of shares in February and March 2026 under the Company's existing $110 million at-the-market offering facility that was established in November 2025.
"2025 was a pivotal year for Nektar as we saw successful and transformative Phase 2 data readouts for rezpegaldesleukin," said Howard W. Robin, President and CEO of Nektar. "The data highlighted the promise and differentiation of our novel Treg mechanism in two inflammatory dermatological disease settings of atopic dermatitis and alopecia areata. In early 2026, we reported the 52-week treatment data for rezpegaldesleukin. These data provide hope that complete clearance of disease could be possible for patients with monthly and quarterly maintenance dosing of rezpegaldesleukin. With our strengthened financial position following the recent financing, we look forward to initiating our Phase 3 program in atopic dermatitis in June of this year, while we continue to advance our earlier TNFR2 agonist antibody and bispecific program toward the clinic."
Summary of Financial Results
Revenue in the fourth quarter of 2025 was $21.8 million as compared to $29.2 million in the fourth quarter of 2024. Revenue for the full year of 2025 was $55.2 million compared to $98.4 million in 2024. Revenue primarily decreased year-over-year because we no longer recognize product sales due to the December 2024 sale of the Huntsville manufacturing facility, as well as a decrease in non-cash royalty revenue.
Total operating costs and expenses in the fourth quarter of 2025 were $49.5 million as compared to $14.8 million in the fourth quarter of 2024. Total operating costs and expenses for 2025 were $195.3 million compared to $203.6 million in 2024. In the fourth quarter of 2024, we recorded a one-time $40.4 million gain from the sale of the Huntsville manufacturing facility. Excluding this gain, operating expenses for the fourth quarter and full year of 2025 decreased due to the elimination of cost of goods sold following the sale of the Huntsville manufacturing facility.
R&D expense in the fourth quarter of 2025 was $29.7 million as compared to $28.7 million for the fourth quarter of 2024. For the full year of 2025, R&D expense was $117.3 million compared to $120.9 million in 2024. R&D expense decreased for full year of 2025 primarily due to a decrease in expense for the development of NKTR-255, partially offset by an increase in expense for the development of rezpegaldesleukin.
G&A expense was $11.2 million in the fourth quarter of 2025 as compared to $17.1 million in the fourth quarter of 2024. G&A expense was $68.7 million for 2025 compared to $76.8 million in 2024. G&A expense decreased for both the fourth quarter and the full year of 2025 due to decreases in facilities and stock-based compensation expenses.
Non-cash restructuring and impairment charges were $8.6 million in the fourth quarter of 2025 and $9.3 million for the full year of 2025, as compared to $1.4 million in the fourth quarter of 2024 and $15.7 million in the full year of 2024. These non-cash charges are related to the declining San Francisco commercial real estate market and real estate lease obligations held by Nektar.
In the first quarter of 2025, we began accounting for our investment in the new portfolio company, Gannet BioChem, under the equity method of accounting which calculates our gain or loss based on the change in our share of Gannet BioChem's equity each quarter. This resulted in non-cash losses from the equity method investment of $1.3 million in the fourth quarter of 2025 and $8.7 million for the full year of 2025.
Net loss for the fourth quarter of 2025 was $36.1 million or $1.78 basic and diluted net loss per share as compared to net income of $7.3 million or $0.521 basic and diluted earnings per share in the fourth quarter of 2024. Net loss for 2025 was $164.1 million or $9.73 basic and diluted loss per share compared to a net loss of $119.0 million or $8.681 basic and diluted net loss per share in 2024. Excluding the $8.7 million non-cash loss from our equity method investment in Gannet BioChem, and the $9.3 million restructuring and impairment charges, net loss, on a non-GAAP basis, for the full year of 2025 was $146.0 million or $8.66 basic and diluted net loss per share.

Cautionary Note Regarding Forward-Looking Statements
This press release contains forward-looking statements which can be identified by words such as: "will," "develop," "potential," "evaluate," "target," "address," "may," "initiate" and similar references to future periods. Examples of forward-looking statements include, among others, statements regarding the therapeutic potential of, and future development plans for, rezpegaldesleukin, NKTR-0165, NKTR-0166, NKTR-422, and NKTR-255. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results to differ materially from those indicated in the forward-looking statements include, among others: (i) our statements regarding the therapeutic potential of rezpegaldesleukin, NKTR-0165, NKTR-0166, NKTR-422 and NKTR-255 are based on preclinical and clinical findings and observations and are subject to change as research and development continue; (ii) rezpegaldesleukin, NKTR-0165, NKTR-0166, NKTR-422 and NKTR-255 are investigational agents and continued research and development for these drug candidates is subject to substantial risks, including negative safety and efficacy findings in future clinical studies (notwithstanding positive findings in earlier preclinical and clinical studies); (iii) rezpegaldesleukin, NKTR-0165, NKTR-0166, NKTR-422 and NKTR-255 are in clinical development and the risk of failure is high and can unexpectedly occur at any stage prior to regulatory approval; (iv) data reported from ongoing clinical trials are necessarily interim data only and the final results will change based on continuing observations; (v) the timing of the commencement or end of clinical trials and the availability of clinical data may be delayed or unsuccessful due to regulatory delays, slower than anticipated patient enrollment, manufacturing challenges, changing standards of care, evolving regulatory requirements, clinical trial design, clinical outcomes, competitive factors, or delay or failure in ultimately obtaining regulatory approval in one or more important markets; (vi) a Fast Track designation does not increase the likelihood that rezpegaldesleukin will receive marketing approval in the United States; (vii) patents may not issue from our patent applications for our drug candidates, patents that have issued may not be enforceable, or additional intellectual property licenses from third parties may be required; and (viii) certain other important risks and uncertainties set forth in our Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 7, 2025. Any forward-looking statement made by us in this press release is based only on information currently available to us and speaks only as of the date on which it is made. We undertake no obligation to update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.
