ImmunityBio, Inc. ((IBRX), a commercial-stage biotechnology company, announced today preliminary select operational results for the fiscal quarter ending March 31, 2026. ImmunityBio reported preliminary net product revenue of approximately $44.2 million during the three-month period ending March 31, 2026, with net product revenue growth in every quarter since ANKTIVA's commercial launch, including a 168% increase over Q1 2025. This builds on full-year 2025 net product revenue of $113 million, a 700% increase over full-year 2024. Q1 2026 net product revenue also represents a 15% sequential increase over the $38.3 million earned during Q4 2025.

ANKTIVA is now approved or authorized across five regulatory jurisdictions, representing approximately 34 countries. Additionally, the pivotal BCG-naïve CIS trial (QUILT-2.005) is fully enrolled, with the IDMC confirming no additional enrollment is required. A supplemental BLA submission is on track for 2026.

The Company ended the quarter with an estimated $380.9 million in cash, cash equivalents and marketable securities as of March 31, 2026.

"ANKTIVA's continued momentum reflects growing physician adoption and disciplined commercial execution," said Richard Adcock, President and CEO of ImmunityBio. "Following strong growth in 2025, we are focused on scaling in the U.S. and expanding across an increasing number of global markets."

"The sustained momentum of ANKTIVA reflects its growing commercial adoption in the BCG-unresponsive NMIBC CIS setting and feedback from treating urologists has been consistently positive," said Patrick Soon-Shiong, M.D., Founder, Executive Chairman and Global Chief Scientific and Medical Officer of ImmunityBio. "Across our clinical programs, we are seeing strong enrollment and growing investigator participation, supporting advancement of our broader pipeline. Full enrollment of our pivotal BCG-naïve CIS with or without papillary disease trial, with IDMC confirmation of adequate statistical power further strengthen the expanding body of clinical evidence supporting ANKTIVA in the NMIBC bladder cancer setting. With our BCG-unresponsive NMIBC with papillary-only disease supplemental BLA now filed and our commitment to our pipeline development across multiple solid and liquid tumor types, we remain focused on advancing new treatment options for patients with bladder cancer and other indications."
