Well capitalized with operating runway anticipated into 2029

Company to present at 44th Annual J.P. Morgan Healthcare Conference on Tuesday, January 13th at 9:00 a.m. PT

CAMBRIDGE, Mass. - January 12, 2026 - Nuvalent, Inc. (Nasdaq: NUVL), a clinical-stage biopharmaceutical company focused on creating precisely targeted therapies for clinically proven kinase targets in cancer, today highlighted pipeline progress and outlined key anticipated milestones towards its first potential U.S. commercial launch under its "OnTarget 2026" operating plan.

As part of this plan, Nuvalent anticipates the following 2026 milestones:

"Over the past two years, the Nuvalent team has seamlessly executed against our OnTarget 2026 operating plan towards our goal of a first potential FDA approval, ending 2025 with the recent FDA acceptance of our NDA for zidesamtinib in TKI pre-treated ROS1-positive NSCLC and commercial preparedness activities well underway," said James Porter, Ph.D., Chief Executive Officer at Nuvalent. "If zidesamtinib is approved, a first commercial launch in 2026 would be a transformative moment for Nuvalent and the first step towards realizing our mission of becoming a sustainable company capable of not only discovering and developing, but delivering new medicines for patients with cancer."

"With cash runway anticipated into 2029, our strong financial position enables us to focus on the execution of a first U.S. launch while also supporting the continued advancement and expansion of both

our commercial and development portfolios," said Alexandra Balcom, Chief Financial Officer at Nuvalent. "We have completed a pre-NDA meeting with the FDA for our ALK program and plan to move forward with an NDA submission of the data for TKI pre-treated patients with ALK-positive NSCLC from our ALKOVE-1 study of neladalkib in the first half of this year. In the second half of the year, we anticipate submitting data to support a potential indication expansion for zidesamtinib in ROS1-positive NSCLC, and growing our discovery portfolio with a new development candidate. Together, we believe the achievement of these anticipated 2026 milestones would position Nuvalent for continued, long-term growth driven by delivering meaningful impact for patients with NSCLC and beyond."

2025 Year-End Cash and Guidance

Nuvalent ended 2025 with approximately $1.4 billion in cash, cash equivalents and marketable securities (unaudited), which, based on its current operating plans, is expected to fund its operations into 2029. This amount is a preliminary, unaudited estimate only as of today, could change following completion of year-end closing procedures, and does not present all information necessary for an understanding of the company's financial position as of December 31, 2025.

Presentation at 44th Annual J.P. Morgan Healthcare Conference

Dr. Porter will present at the 44th Annual J.P. Morgan Healthcare Conference in San Francisco on Tuesday, January 13, 2026 at 9:00 a.m. PT. A live webcast will be available in the Investors section of Nuvalent's website at www.nuvalent.com, and will be archived for 30 days following the conference.

About Zidesamtinib

Zidesamtinib is an investigational, brain-penetrant, ROS1-selective inhibitor created with the aim to overcome limitations observed with currently available ROS1 inhibitors. Zidesamtinib is designed to remain active in tumors that have developed resistance to currently available ROS1 inhibitors, including tumors with treatment-emergent ROS1 mutations such as G2032R. In addition, zidesamtinib is designed for central nervous system (CNS) penetrance to improve treatment options for patients with brain metastases, and to avoid inhibition of the structurally related tropomyosin receptor kinase (TRK) family. Together, these characteristics have the potential to avoid TRK-related CNS adverse events seen with dual TRK/ROS1 inhibitors and to drive deep, durable responses for patients across all lines of therapy.

Based on results for tyrosine kinase inhibitor (TKI) pre-treated patients with advanced ROS1-positive non-small cell lung cancer (NSCLC) enrolled in the global registrational ARROS-1 Phase 1/2 clinical trial, the U.S. Food and Drug Administration (FDA) has accepted for filing Nuvalent's NDA submission for zidesamtinib for the treatment of adult patients with locally advanced or metastatic ROS1-positive NSCLC who received at least 1 prior ROS1 TKI. The application has been assigned a Prescription Drug User Fee Act (PDUFA) target action date of September 18, 2026. Zidesamtinib has received breakthrough therapy designation for the treatment of patients with ROS1-positive metastatic NSCLC who have been previously treated with 2 or more ROS1 TKIs and orphan drug designation for ROS1-positive NSCLC.

About Neladalkib

Neladalkib is an investigational, brain-penetrant, ALK-selective inhibitor created with the aim to overcome limitations observed with currently available ALK inhibitors. Neladalkib is designed to remain active in tumors that have developed resistance to first-, second-, and third-generation ALK inhibitors, including tumors with single or compound treatment-emergent ALK mutations such as G1202R. In addition, neladalkib is designed for central nervous system (CNS) penetrance to improve treatment options for patients with brain metastases, and to avoid inhibition of the structurally related tropomyosin receptor kinase (TRK) family. Together, these characteristics have the potential to avoid TRK-related

CNS adverse events seen with dual TRK/ALK inhibitors and to drive deep, durable responses for patients across all lines of therapy. Neladalkib has received breakthrough therapy designation from the U.S. Food and Drug Administration (FDA) for the treatment of patients with locally advanced or metastatic ALK-positive non-small cell lung cancer (NSCLC) who have been previously treated with 2 or more ALK tyrosine kinase inhibitors and orphan drug designation for ALK-positive NSCLC.

About NVL-330

NVL-330 is an investigational, brain-penetrant, HER2-selective tyrosine kinase inhibitor designed to address the combined medical need of treating HER2-mutant tumors, including those with HER2 exon 20 insertion mutations, avoiding treatment related adverse events due to off-target inhibition of wild-type EGFR, and treating brain metastases.
