SAN FRANCISCO, Aug. 13, 2026 /PRNewswire/ — Nektar Therapeutics (Nasdaq: NKTR), a clinical-stage biotechnology company focused on development of novel immunology therapies, today reported financial results for the second quarter ended June 30, 2026.

Cash and investments in marketable securities on June 30, 2026, were $1,023.4 million as compared to $245.8 million on December 31, 2025. 

“This year continues to be a transformative year for Nektar as we advance our lead program, rezpegaldesleukin, into Phase 3 clinical trials,” said Howard W. Robin, President and Chief Executive Officer of Nektar. “We initiated the first Phase 3 ZENITH AD trials in atopic dermatitis in July, and we plan to start a single registrational Phase 3 study in alopecia areata in early 2027. Our Phase 3 program establishes a clear path to the first BLA submission for rezpegaldesleukin in 2029. With its novel T-reg mechanism, rezpegaldesleukin is uniquely positioned to provide benefit for patients across a number of chronic autoimmune conditions. Importantly, our financial position is strong with over one billion dollars in cash and investments at the end of the quarter, and a cash runway that extends into the third quarter of 2028, past the initial Phase 3 data readouts expected in mid-2028.”

Revenue in the second quarter of 2026 was $10.1 million as compared to $11.2 million in the second quarter of 2025. Revenue for the first half of 2026 was $21.0 million as compared to $21.6 million in the first half of 2025.

Total operating costs and expenses in the second quarter of 2026 were $52.5 million as compared to $47.4 million in the second quarter of 2025. Total operating costs and expenses were $102.4 million for both the first half of 2026 and first half of 2025. Operating expenses for the second quarter and first half of 2026 reflect an increase in R&D expenses, offset by a decrease in G&A expenses.

R&D expense in the second quarter of 2026 was $39.1 million as compared to $29.9 million for the second quarter of 2025. R&D expense in the first half of 2026 was $74.8 million as compared to $60.4 million for the first half of 2025. R&D expense increased primarily due to the commencement of activities to support the Phase 3 ZENITH AD program in atopic dermatitis as well as manufacturing activities associated with rezpegaldesleukin.

G&A expense was $12.8 million in the second quarter of 2026 as compared to $17.1 million in the second quarter of 2025. G&A expense was $26.2 million in the first half of 2026 as compared to $41.4 million in the first half of 2025. G&A expense decreased primarily due to a decrease in legal expenses.

Our non-cash loss from our equity method investment in Gannet BioChem was $0.3 million in the second quarter of 2026, as compared to $2.4 million in the second quarter of 2025. The non-cash loss from the equity method investment was $2.1 million in the first half of 2026, as compared to $6.8 million in the first half of 2025.

Net loss for the second quarter of 2026 was $40.6 million or $1.23 basic and diluted net loss per share as compared to net loss of $41.6 million or $2.95 basic and diluted loss per share in the second quarter of 2025. Net loss in the first half of 2026 was $85.5 million or $2.96 basic and diluted net loss per share as compared to a net loss of $92.5 million or $6.57 basic and diluted loss per share in the first half of 2025.

Second Quarter 2026 Business Highlights

• In July 2026, Nektar announced the initiation of the first two global registrational trials in the Phase 3 ZENITH AD program evaluating rezpegaldesleukin in moderate-to-severe atopic dermatitis. The program will include a total of three randomized, double-blind, placebo-controlled trials: ZENITH AD-1 and ZENITH AD-2 will enroll biologic and systemic JAK inhibitor treatment naive patients, and ZENITH AD-3 will enroll patients with prior biologic and/or systemic JAK inhibitor treatment experience.
• In April 2026, Nektar completed an underwritten public offering of its common stock resulting in $373.8 million of gross proceeds.
• In April 2026, Nektar announced positive 52-week topline results from the 16-week blinded treatment extension of the Phase 2b REZOLVE-AA study, demonstrating deepening of responses to rezpegaldesleukin in patients with severe-to-very-severe alopecia areata with continued twice-monthly dosing.

Cautionary Note Regarding Forward-Looking Statements

This press release contains forward-looking statements which can be identified by words such as: “will”, “develop,” “potential,” “expect”, “may,” “plan” and similar references to future periods. Examples of forward-looking statements include, among others, statements regarding the safety and efficacy profile and therapeutic potential of, and future development plans for, rezpegaldesleukin, NKTR-0165, NKTR-0166, and NKTR-422, potential patient preferences and market adoption related thereto, and plans and timing of future clinical trials and data releases. 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 and NKTR-422 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 and NKTR-422 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 and NKTR-422 are in various stages of preclinical and clinical development, the risk of failure is high and can unexpectedly occur at any stage of development, and there can be no assurance that any such drug candidate will obtain regulatory approval; (iv) data reported from ongoing clinical trials may be preliminary or interim and may change as additional patient data becomes available or as continuing observations, verifications and analysis are completed; (v) the timing of the initiation or completion 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 filings with the Securities and Exchange Commission (SEC), including the risks and uncertainties described under the heading “Risk Factors” in our most recent Annual Report on Form 10-K or Quarterly Report Form 10-Q, as such risks and uncertainties may be amended or supplemented by our other filings with the SEC. 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.
