ImmunityBio, Inc. (NASDAQ: IBRX), a commercial-stage immunotherapy company, today announced full-year 2025 financial and operational highlights, including approximately $113 million in net product revenue for ANKTIVA, representing an approximately 700% increase year-over-year. The Company also reported a 750% increase in unit sales volume and a 20% quarter-over-quarter increase in net product revenue, demonstrating sustained commercial momentum. In parallel, ImmunityBio expanded its global regulatory footprint to 33 countries across four jurisdictions and secured the first approval for ANKTIVA in combination with checkpoint inhibitors for lung cancer.

Global Regulatory Approvals

ANKTIVA in combination with BCG for the treatment of BCG-unresponsive non-muscle invasive bladder cancer (NMIBC) carcinoma in situ (CIS), with or without papillary tumors, is now authorized across four major regulatory jurisdictions encompassing 33 countries:

• United States: FDA approval (April 2024)
• United Kingdom: MHRA authorization (July 2025)
• Kingdom of Saudi Arabia: SFDA accelerated approval for BCG-unresponsive NMIBC CIS (January 2026) and conditional accelerated approval for metastatic NSCLC in combination with checkpoint inhibitors (January 2026), the first jurisdiction globally to authorize ANKTIVA for lung cancer
• European Union: European Commission conditional marketing authorization covering all 27 EU member states plus Iceland, Norway, and Liechtenstein (February 2026)

This global regulatory footprint of 33 countries was established in under two years from initial 2024 FDA approval, representing the most rapid international expansion for an immunotherapy in this indication.

First Approval for Lung Cancer and Label Expansion Plans

In January 2026, the SFDA granted conditional accelerated approval for ANKTIVA^® in combination with checkpoint inhibitors for the treatment of metastatic NSCLC, making Saudi Arabia the first jurisdiction globally to authorize ANKTIVA outside of bladder cancer. The commercial launch in Saudi Arabia is planned within 60 days of approval. Submissions to multiple additional regulatory authorities (Ex-USA) for accelerated approval are planned for 2026, with discussions with the U.S. FDA regarding an accelerated approval pathway also planned for 2026. The Company is pursuing further label expansion across multiple tumor types and for the treatment of chemotherapy-induced lymphopenia, supported by ongoing clinical trial programs.

Long-Term Patent Protection

Multiple issued patents, including U.S. Patent Nos, protect the combination of ANKTIVA plus checkpoint inhibitor therapy. 9,925,247 and 11,071,774, with patent terms extending beyond 2035. These patents cover the combination of IL-15 receptor agonist therapy with anti-PD-1 and anti-PD-L1 checkpoint inhibitors across multiple tumor types, providing long-term exclusivity protection for ANKTIVA’s expanding combination indications.

“In under two years from initial FDA approval, ImmunityBio has built a global commercial footprint spanning 33 countries across four regulatory jurisdictions, with $113 million in full-year net product revenue representing 700% year-over-year growth,” said Dr. Patrick Soon-Shiong, Founder, Executive Chairman, and Global Chief Scientific and Medical Officer of ImmunityBio. “The SFDA’s accelerated approval of ANKTIVA in combination with checkpoint inhibitors for metastatic NSCLC marks a defining moment for the Company, the first authorization of ANKTIVA beyond bladder cancer and the first validation of its role as a lymphocyte-stimulating agent in solid tumors. We are now pursuing accelerated approvals in multiple additional jurisdictions and engaging with the U.S. FDA on a regulatory pathway for this indication. In parallel, our pipeline spans over 30 active and planned clinical trials across 10 tumor types, including randomized trials in BCG-naïve bladder cancer, first-line NSCLC, glioblastoma, and pancreatic cancer. ANKTIVA’s mechanism activating NK cells, CD8+ T cells, and memory T cells without expanding regulatory T cells positions it as a backbone immunotherapy across the oncology landscape, and our expanding patent portfolio protecting these combinations through 2035 and beyond ensures long-term commercial exclusivity.”

Commercial Partnerships and Global Infrastructure

ImmunityBio has established strategic partnerships and infrastructure to support the global commercial launch of ANKTIVA:

• European Union and United Kingdom: Partnered with Accord Healthcare to deploy over 100 sales, medical, and marketing professionals across 30 countries in the EU, UK, and European Free Trade Association (EFTA) member states. ImmunityBio also established an Irish subsidiary in Dublin to support European distribution and commercialization strategy.
• Kingdom of Saudi Arabia: Partnering with BioPharma & Cigalah to expand access to ANKTIVA in Saudi Arabia and, over time, throughout the MENA region. ImmunityBio has formed a KSA subsidiary to support commercial launch operations in the Kingdom.

“Our 2025 financial results reflect the growing clinical adoption of ANKTIVA as a foundational backbone of immunotherapy for bladder cancer,” said Richard Adcock, President and CEO of ImmunityBio. “Our partnership with Accord Healthcare deploys over 100 commercial professionals across 30 European countries, and our collaboration with BioPharma & Cigalah positions us for rapid commercial execution in Saudi Arabia and the broader MENA region. With subsidiaries now established in Dublin and the Kingdom of Saudi Arabia, we have the infrastructure to support sustained commercial growth across all 33 countries where ANKTIVA is authorized. As we advance toward initial international commercial activities, we remain focused on disciplined execution: completing enrollment in our BCG-naïve randomized trial with a BLA filing targeted by Q4 2026, expanding the ANKTIVA label into lung cancer and lymphopenia, and converting our 700% revenue growth trajectory into durable, long-term value for shareholders.”

Selling, General and Administrative Expense

SG&A expense decreased $18.8 million to $150.0 million during the year ended December 31, 2025, as compared to $168.8 million during the year ended December 31, 2024. The decrease was primarily driven by lower costs related to litigation settlements and commercial consulting activities, partially offset by higher stock-based compensation expense, recruiting and training expenses, salaries, benefits and commissions, and travel expenses due to growing sales and marketing activities.

Net Loss Attributable to ImmunityBio Common Stockholders

Net loss attributable to ImmunityBio common stockholders was $351.4 million during the year ended December 31, 2025, compared to $413.6 million during the year ended December 31, 2024. This reduction of loss was primarily driven by increased product revenue, lower SG&A expense described above, lower related-party interest expense, and changes in the fair value of warrant liabilities, partially offset by higher R&D expense described above, changes in the fair value of derivative liabilities and a related-party convertible note, an increase in interest expense related to the revenue interest liability, and lower interest and investment income.

About ImmunityBio

ImmunityBio, Inc. is a biotechnology company focused on innovating, developing, and commercializing next-generation immunotherapies designed to activate the patient’s immune system and deliver durable protection against cancer and infectious diseases. Our approach harnesses both the adaptive and innate immune systems with the goal of restoring immune function and generating lasting immunological memory in patients. At the core of our strategy is the Cancer BioShield platform, which is designed to stimulate critical lymphocytes, including natural killer (NK) cells, cytotoxic T cells, and memory T cells via our proprietary IL-15 superagonist, ANKTIVA^® (nogapendekin alfa inbakicept). Our Cancer BioShield platform is anchored by this antibody-cytokine fusion protein and is complemented by a portfolio that includes adenovirus-vectored vaccines, allogeneic (off-the-shelf) and autologous NK-cell therapies, and additional immunomodulators intended to promote immunogenic cell death and support durable immune responses while potentially reducing reliance on high-dose chemo-radiation therapy.

About ANKTIVA

ANKTIVA (nogapendekin alfa inbakicept) is our lead biologic product and a first-in-class IL-15 receptor superagonist antibody-cytokine fusion protein. We are commercializing ANKTIVA for the treatment of BCG-unresponsive NMIBC with CIS, with or without papillary tumors. ANKTIVA has received U.S. Food and Drug Administration (FDA) Breakthrough Therapy designation for use in BCG-unresponsive NMIBC with CIS in adult patients with or without papillary tumors.

ANKTIVA is now approved in the U.S., UK, and Saudi Arabia for BCG-unresponsive NMIBC with CIS with or without papillary tumors. In February 2026, the European Commission granted conditional marketing authorization in the EU for ANKTIVA for the same indication. In addition, ANKTIVA is conditionally approved in Saudi Arabia, for use in combination with a CPI, for the treatment of adult patients with metastatic NSCLC whose disease has progressed following standard-of-care therapy. The approved labels highlight ANKTIVA’s ability to simultaneously activate NK cells, cytotoxic T cells, and memory T cells.

ANKTIVA in combination with our CAR-NK therapy (PD-L1 t-haNK) has received RMAT designation from the FDA for use in combination with chemotherapy/radiotherapy for reversal of lymphopenia and treatment of relapsed locally advanced or metastatic pancreatic cancer. Separately, the FDA has authorized an EAP for ANKTIVA to treat lymphopenia in adult patients with refractory or relapsed solid tumors, regardless of tumor type, who have progressed following first-line standard-of-care treatment, including chemotherapy, radiation, or immunotherapy. The EAP includes patients with solid tumors who have failed first-line therapy and have a low ALC (ALC <1,000/μL).

Important Safety Information

INDICATION AND USAGE:

ANKTIVA^® is an interleukin-15 (IL-15) receptor agonist indicated with Bacillus Calmette-Guérin (BCG) for the treatment of adult patients with BCG-unresponsive non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS) with or without papillary tumors.

WARNINGS AND PRECAUTIONS: Risk of Metastatic Bladder Cancer with Delayed Cystectomy. Delaying cystectomy can lead to the development of muscle-invasive or metastatic bladder cancer, which can be lethal. If patients with CIS do not have a complete response to treatment after a second induction course of ANKTIVA^® with BCG, reconsider cystectomy.

DOSAGE AND ADMINISTRATION: For Intravesical Use Only. Do not administer by subcutaneous or intravenous routes.

USE IN SPECIFIC POPULATIONS: Pregnancy: May cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception.
