The company is engaging with the FDA on potential opportunities for line-agnostic expansion for zidesamtinib and expects to report pivotal data for neladalkib in TKI pre-treated patients by year-end 2025.

Management Comments

• We believe that our existing cash, cash equivalents and marketable securities will be sufficient to fund our operating expenses and capital expenditure requirements for at least 12 months from the date of issuance of these condensed consolidated financial statements.
• We expect to incur significant expenses for the foreseeable future in connection with ongoing activities, particularly if and as we continue to advance zidesamtinib, neladalkib and NVL-330 in clinical development.
• We will not generate revenue from product sales unless and until we successfully complete clinical development of, obtain regulatory approval for and successfully commercialize one or more of our product candidates.
• Our existing cash, cash equivalents and marketable securities will not be sufficient to fund all of our product candidates through regulatory approval, and we may need to raise additional capital to complete the development and commercialization of our product candidates.

Industry Context

Nuvalent operates in the highly competitive and rapidly evolving field of oncology, specifically focusing on precisely targeted therapies for cancer-associated genomic alterations. This niche requires significant R&D investment and faces high attrition rates. The company's strategy of developing highly selective kinase inhibitors aims to overcome limitations of existing therapies like resistance, off-target adverse events, and limited brain penetrance, positioning its candidates for potential utility earlier in treatment paradigms. The industry is seeing increasing regulatory scrutiny, particularly regarding accelerated approval pathways and drug pricing, as well as geopolitical risks impacting global supply chains and collaborations. The focus on biomarker-driven patient populations, while offering precision, also limits the addressable market size compared to broader cancer populations.

Comparison to Industry Standards

• Nuvalent's zidesamtinib (NVL-520) is competing in the ROS1-positive NSCLC space against four FDA-approved TKIs: crizotinib, entrectinib, repotrectinib, and taletrectinib. The reported 44% ORR in TKI pre-treated patients and 89% ORR in TKI-naive patients, along with strong intracranial activity, suggests a competitive profile, especially given its design to address resistance and brain metastases, which are common challenges with existing ROS1 TKIs.
• For neladalkib (NVL-655), Nuvalent is targeting ALK-positive NSCLC, a field with six FDA-approved ALK inhibitors (crizotinib, lorlatinib, ceritinib, alectinib, brigatinib, and ensartinib). The initiation of a Phase 3 trial against ALECENSA (alectinib), a current standard of care, indicates confidence in neladalkib's potential to offer a superior profile, particularly as a brain-penetrant ALK-selective inhibitor designed to overcome resistance to 1G, 2G, and 3G ALK inhibitors.
• In the HER2 mutant NSCLC space, NVL-330 is in Phase 1a/1b, competing with fam-trastuzumab deruxtecan-nxki (an antibody-drug conjugate) and other kinase inhibitors in development like zongertinib (BI-1810631) and pyrotinib. Nuvalent's focus on a brain-penetrant, HER2-selective inhibitor designed to avoid wild-type EGFR inhibition aims to differentiate it in a market currently lacking approved kinase inhibitors for this specific patient population.

Related Party Transactions

• The company has revenue sharing agreements with Deerfield Healthcare Innovations Fund, L.P. and Deerfield Private Design Fund, IV, L.P. (collectively, Deerfield), and the company's scientific founder.
• These agreements involve paying a fixed low single-digit percentage rate of net sales of certain commercial products.
• The payment obligation expires on the later of 12 years from the first commercial sale in a country or the expiration of the last-to-expire patent in that country.
• The liability with Deerfield is accounted for at fair value, with changes recognized in the consolidated statements of operations and comprehensive loss.
• The fair value of the related party revenue share liability was estimated to be $25.4 million as of June 30, 2025, an increase from $17.9 million at December 31, 2024, due to changes in assumptions, primarily related to the probability and timing of obtaining regulatory approval.
• A material increase in the fair value of this liability is anticipated during the three months ended September 30, 2025, due to the progression of clinical trials subsequent to June 30, 2025.
• No liability has been accrued for the obligation to the scientific founder as of June 30, 2025, or December 31, 2024, as no net sales have been recorded.
