Nektar Therapeutics Reports Third Quarter 2025 Financial Results

SAN FRANCISCO, Nov. 6, 2025 /PRNewswire/ -- Nektar Therapeutics (Nasdaq: NKTR) today reported financial results for the third quarter ended September 30, 2025.

Cash and investments in marketable securities on September 30, 2025 were $270.2 million as compared to $269.1 million on December 31, 2024. Nektar's cash and marketable securities at September 30, 2025 includes $107.2 million of net proceeds from the secondary offering closed on July 2, 2025 and $34.3 million of net proceeds for the issuance of registered stock under the Company's filed at-the-market, "ATM", offering. Following the end of the third quarter, an additional $38.3 million of net proceeds were also raised from the ATM offering in October 2025. We expect our cash and investments in marketable securities to support our operations into the second quarter of 2027.

"We have made tremendous progress advancing rezpegaldesleukin, and the emerging data from the REZOLVE-AD study continue to demonstrate a highly differentiated profile for this first-in-class, novel regulatory T cell mechanism in moderate-to-severe atopic dermatitis," said Howard W. Robin, President and CEO of Nektar. "We will present important new findings from REZOLVE-AD this weekend at the ACAAI Scientific Meeting highlighting the potential of rezpegaldesleukin to treat atopic dermatitis and co-morbid asthma, which occurs in about 25% of atopic dermatitis patients. These compelling data give rezpegaldesleukin a unique position in the competitive landscape as this efficacy signal has not been observed with other biologic mechanisms recently approved or in advanced development. Notably, this year's Nobel Prize in Physiology or Medicine, was awarded for discoveries establishing FOXP3-positive Tregs as essential for peripheral immune tolerance, and we were humbled that rezpegaldesleukin data were referenced in the background documents from the Nobel Committee. Finally, we look forward to reporting in December the topline data for rezpegaldesleukin in patients with severe-to-very-severe alopecia areata, a chronic auto-immune condition that greatly impacts quality of life and mental health for these patients."

Summary of Financial Results

Revenue in the third quarter of 2025 was $11.8 million as compared to $24.1 million in the third quarter of 2024. Revenue for the first nine months of 2025 was $33.4 million compared to $69.3 million in the first nine months of 2024. Revenue has decreased year over year because we no longer recognize product sales due to the sale of the Huntsville manufacturing facility in December 2024.

Total operating costs and expenses in the third quarter of 2025 were $43.5 million as compared to $58.5 million in the third quarter of 2024. Total operating costs and expenses in the first nine months of 2025 were $145.9 million compared to $188.8 million in the first nine months of 2024. Operating costs and expenses for the third quarter and first nine months of 2025 decreased due to the elimination of cost of goods sold following the sale of the Huntsville manufacturing facility and deceases in research and development expenses, as well as non-cash impairment charges recorded in the first nine months of 2024.

R&D expense in the third quarter of 2025 was $27.3 million as compared to $35.0 million for the third quarter of 2024. For the first nine months of 2025, R&D expense was $87.6 million compared to $92.2 million in the first nine months of 2024. R&D expense decreased in the first nine months of 2025 primarily due to a decrease in expense for the development of NKTR-255, partially offset by an increase in expenses for the development of rezpegaldesleukin and NKTR-0165.

G&A expense was $16.1 million in the third quarter of 2025 as compared to $19.0 million in the third quarter of 2024. G&A expense was $57.5 million for the first nine months of 2025 compared to $59.6 million in the first nine months of 2024. G&A expense decreased for both the third quarter and the first nine months of 2025 due to decreases in facilities and stock-based compensation expenses offset by an increase in legal expenses.

Non-cash restructuring and impairment charges were not material in the third quarter and the first nine months of 2025. Non-cash restructuring and impairment charges were less than $0.1 million in the third quarter of 2024 and $14.3 million in the first nine months of 2024. These non-cash charges were 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 $0.5 million in the third quarter of 2025 and $7.4 million for the first nine months of 2025.

Net loss for the third quarter of 2025 was $35.5 million or $1.87 basic and diluted loss per share as compared to a net loss of $37.1 million or $2.66¹ basic and diluted loss per share in the third quarter of 2024. Net loss in the first nine months of 2025 was $128.0 million or $8.14 basic and diluted loss per share compared to a net loss of $126.2 million or $9.27¹ basic and diluted loss per share in the first nine months of 2024. Excluding the $0.5 million and $7.4 million non-cash loss from our equity method investment in Gannet BioChem, net loss, on a non-GAAP basis, for the third quarter and the first nine months of 2025 were $35.0 million and $120.6 million, respectively, or $1.85 and $7.67 basic and diluted loss per share, respectively.

Cautionary Note Regarding Forward-Looking Statements

This press release contains forward-looking statements which can be identified by words such as: "will," "develop," "potential," "target," "address," "may," "expect" 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 August 8, 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.
