Nektar Therapeutics Announces Third Quarter 2026 Financial Results

SAN FRANCISCO, Nov. 12, 2026 /PRNewswire/ -- Nektar Therapeutics (Nasdaq: NKTR) today announced its financial results for the third quarter ended September 30, 2026, and provided a business update.

Cash and investments in marketable securities on September 30, 2026, were $952.9 million as compared to $245.8 million on December 31, 2025.

"This was a pivotal quarter for Nektar as we moved rezpegaldesleukin quickly into Phase 3 development," said Howard Robin, President and Chief Executive Officer of Nektar. "We have now initiated all three global ZENITH AD registrational trials in atopic dermatitis and our global ZENITH AA registrational trial in alopecia areata is on track to begin in December, earlier than previously planned. The strong body of clinical and translational data generated to-date for rezpegaldesleukin reinforce our conviction in its novel and differentiated Treg mechanism, which targets multiple inflammatory pathways that underpin chronic autoimmune disease. We believe rezpegaldesleukin has the potential to offer an important new therapeutic approach for patients, and we're focused on advancing to our topline data readouts in the summer of 2028 with the first BLA filing in 2029."

Revenue in the third quarter of 2026 was $9.4 million as compared to $11.8 million in the third quarter of 2025. Revenue for the first nine months of 2026 was $30.4 million as compared to $33.4 million in the first nine months of 2025.

Total operating costs and expenses in the third quarter of 2026 were $67.2 million as compared to $43.5 million in the third quarter of 2025. Total operating costs and expenses were $169.6 million in the first nine months of 2026 as compared to $145.9 million in the first nine months of 2025. Operating expenses for 2026 reflect an increase in research and development (R&D) expenses for both the third quarter and first nine months of 2026 and an increase in general and administrative (G&A) expenses for the third quarter of 2026 but a decrease in G&A expenses for the first nine months of 2026.

R&D expense in the third quarter of 2026 was $44.1 million as compared to $27.3 million for the third quarter of 2025. R&D expense in the first nine months of 2026 was $118.9 million as compared to $87.6 million for the first nine months of 2025. R&D expense increased primarily due to activities to support the Phase 3 ZENITH AD program in atopic dermatitis and the Phase 3 ZENITH AA program in alopecia areata, as well as manufacturing activities associated with rezpegaldesleukin.

G&A expense was $24.6 million in the third quarter of 2026 as compared to $16.1 million in the third quarter of 2025. G&A expense was $50.8 million in the first nine months of 2026 as compared to $57.5 million in the first nine months of 2025. G&A expense increased for the third quarter of 2026 but decreased in the first nine months of 2026, primarily due to an increase in legal expenses in the third quarter of 2026 and a decrease in legal expenses in the first nine months of 2026.

Our non-cash loss from our equity method investment in Gannet BioChem was $0.6 million in the third quarter of 2026, as compared to $0.5 million in the third quarter of 2025. The non-cash loss from the equity method investment was $2.7 million in the first nine months of 2026, as compared to $7.4 million in the first nine months of 2025.

Net loss for the third quarter of 2026 was $55.7 million or $1.63 basic and diluted net loss per share as compared to a net loss of $35.5 million or $1.87 basic and diluted loss per share in the third quarter of 2025. Net loss in the first nine months of 2026 was $141.2 million or $4.60 basic and diluted net loss per share as compared to a net loss of $128.0 million or $8.14 basic and diluted loss per share in the first nine months of 2025.

Third Quarter 2026 and Recent Business Highlights

Atopic Dermatitis

• In October 2026, Nektar announced the initiation of ZENITH AD-3, the third and final registrational trial in the global Phase 3 ZENITH AD program evaluating rezpegaldesleukin in atopic dermatitis. ZENITH AD-3 is enrolling patients with prior systemic biologic and/or JAK inhibitor treatment experience. The goal is to support a broad label. Initial topline data from the ZENITH AD program are expected in mid-2028, with a BLA submission targeted for 2029.
• In September 2026, data from a 100-patient biomarker sub-study of the Phase 2b REZOLVE-AD study in atopic dermatitis were presented by collaborators at the Icahn School of Medicine at Mount Sinai in a late-breaking oral presentation at the European Academy of Dermatology and Venereology (EADV) Congress 2026. The results showed early molecular responses to rezpegaldesleukin as early as Week 2 across multiple immune pathways that are known to be dysregulated in patients with atopic dermatitis. Additionally, these early serum biomarker changes were associated with subsequent clinical responses at Week 16. These findings support rezpegaldesleukin as a Treg-directed approach to treating heterogeneous inflammatory diseases like atopic dermatitis.
• In August 2026, results from the 16-week induction period of the Phase 2b REZOLVE-AD were published in The Lancet. As previously announced, the study met all primary and key secondary endpoints on the 24 micrograms per kilogram Q2W regimen, including at least a 75% improvement in the Eczema Area and Severity Index (EASI-75), at least a 90% improvement in the Eczema Area and Severity Index (EASI-90), validated Investigator Global Assessment of Atopic Dermatitis (vIGA-AD^TM) response, and Itch Numerical Rating Scale (NRS) response and body surface area (BSA).

• 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, ZENITH AD-2 and ZENITH AD-3.

Alopecia Areata

• In October 2026, data from the 52-week treatment extension cohort and the 6-month off-treatment period in the global Phase 2b REZOLVE-AA study in patients with severe-to-very-severe alopecia areata were presented at EADV 2026. As previously reported, continued rezpegaldesleukin treatment through Week 52 demonstrated clear and consistent separation from placebo on key measures of efficacy. Among the patients who achieved a SALT Score ≤20 from the 52-week treatment cohort, 75% (6/8) maintained that response after four months off treatment and 63% (5/8) maintained it after six months off treatment. Hair regrowth continued for 6 months off treatment with 19% of patients achieving SALT Score ≤10, an improvement from 7% at the end of 52 weeks of treatment. These data support evaluation of less frequent rezpegaldesleukin dosing (Q4W or Q12W) beyond the 52-week induction period for patients who achieve a SALT Score ≤20. The presentations at EADV were discussed on a conference call and webinar hosted by Nektar on October 1st. Dr. Benjamin Ungar, Director of the Alopecia Center of Excellence and Director of the Rosacea & Seborrheic Dermatitis Clinic at the Kimberly and Eric J. Waldman Department of Dermatology at Mount Sinai also participated in the call. A replay can be accessed on the company website here.

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.
