Strengthened leadership team with key internal promotions

CAMBRIDGE, Mass.,May 7, 2026/PRNewswire/ --Nuvalent, Inc.(Nasdaq:NUVL), a clinical-stage biopharmaceutical company focused on creatingpreciselytargeted therapies for clinically proven kinase targets in cancer, today outlined pipeline progress, reiterated key anticipated milestones, and reported first quarter 2026 financial results.

"The forward momentum continues at Nuvalent, with both of our parallel-lead programs advancing toward key US regulatory milestones and the opportunity to bring our first new medicine to patients this year,"said James Porter, Ph.D., Chief Executive Officer of Nuvalent. "We recently submitted our NDA for neladalkib in TKI pre-treated ALK-positive NSCLC and are continuing to build our commercial infrastructure in preparation for a potential US launch of zidesamtinib in TKI pre-treated ROS1-positive NSCLC, if approved."

"Beyond these initial opportunities, we remain focused on progressing our label expansion strategies for ROS1- and ALK-positive NSCLC, as well as our earlier-stage pipeline, with the goal of driving meaningful, long-term impact in NSCLC and beyond. Through these efforts, we believe we are well positioned to realize our vision of becoming a sustainable biotechnology company capable of designing, developing and deliveringpreciselytargeted therapies for patients with cancer."
