The Notes will be general unsecured obligations of Nuvation Bio, with any interest payable semiannually in arrears and will mature on July 1, 2032, unless earlier converted, redeemed or repurchased. Upon conversion, Nuvation Bio will pay or deliver cash, shares of Nuvation Bio’s Class A common stock, par value $0.0001 per share ("Class A common stock"), or a combination of cash and shares of Class A common stock, at its election. The interest rate, initial conversion rate and other terms of the Notes will be determined at the time of pricing of the Offering.

Nuvation Bio expects to use the net proceeds from the Offering (i) to pay the cost of the capped call transactions described below, (ii) to repay in full all obligations under our senior secured loan agreement, and (iii) for general corporate purposes, which may include working capital, operating expenses, capital expenditures and general and administrative expenses.

In connection with the pricing of the Notes, Nuvation Bio expects to enter into capped call transactions with one or more of the underwriters or affiliates thereof and/or other financial institutions (the "Option Counterparties"). If the underwriters exercise their over-allotment option, Nuvation Bio expects to enter into additional capped call transactions. The capped call transactions will cover, subject to customary adjustments, the number of shares of Class A common stock initially underlying the Notes. The capped call transactions are expected generally to reduce the potential dilution to the Class A common stock upon any conversion of Notes and/or offset any cash payments Nuvation Bio is required to make in excess of the principal amount of converted Notes, as the case may be, with such reduction and/or offset subject to a cap.

In connection with establishing their initial hedges of the capped call transactions, Nuvation Bio expects the Option Counterparties or their respective affiliates will enter into various derivative transactions with respect to the Class A common stock concurrently with or shortly after the pricing of the Notes, including with certain investors in the Notes. This activity could increase (or reduce the size of any decrease in) the market price of the Class A common stock or the Notes at that time.

In addition, the Option Counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to the Class A common stock and/or purchasing or selling Class A common stock or other securities of Nuvation Bio in secondary market transactions following the pricing of the Notes and prior to the maturity of the Notes (and are likely to do so during the 40-trading day period beginning on the 41st scheduled trading day prior to the maturity date of the Notes, or, to the extent Nuvation Bio exercises the relevant election under the capped call transactions, following any repurchase, redemption or conversion of the Notes). This activity could also cause or avoid an increase or a decrease in the market price of the Class A common stock or the Notes which could affect a noteholder’s ability to convert the Notes and, to the extent the activity occurs during any observation period related to a conversion of Notes, it could affect the number of shares, if any, and value of the consideration that a noteholder will receive upon conversion of its Notes.

The Notes are being offered pursuant to a "shelf" registration statement on Form S-3 (File No. 333-285621), including a base prospectus, that was previously filed by Nuvation Bio and automatically became effective under the rules of the Securities and Exchange Commission (the "SEC") on March 6, 2025. A preliminary prospectus supplement relating to the Offering will be filed with the SEC and will be available on the website of the SEC at www.sec.gov. When available, copies of the preliminary prospectus supplement and the accompanying prospectus relating to the Offering may be obtained from: Jefferies LLC, Attention: Equity Syndicate Prospectus Department, 520 Madison Avenue, New York, New York 10022, by telephone at 877-821-7388 or by email at [email protected]; Citigroup Global Markets Inc., c/o Broadridge Financial Solutions 1155 Long Island Avenue, Edgewood, NY 11717, by phone at 1-800-831-9146; Cantor Fitzgerald & Co. by mail at Attention: Capital Markets, 110 East 59th Street, New York, NY 10022 or by email at [email protected]; or RBC Capital Markets, LLC, Attn: Equity Capital Markets, 200 Vesey Street, 8th floor, New York, NY 10281, by telephone at 877-822-4089 or by email at [email protected].

Racura Oncology Doses First Patient in Phase 1 HARNESS-1 Trial of RC220 in EGFR-Mutant Non-Small Cell Lung Cancer

On June 25, 2026 Racura Oncology Limited (ASX: RAC), a clinical-stage biopharmaceutical company developing new small molecule based approaches to cancer treatment, reported that the first patient has been dosed with RC220 in HARNESS-1, a Phase 1a/b clinical trial evaluating RC220 in combination with osimertinib in patients with epidermal growth factor receptor-mutant (EGFR-mutant) non-small cell lung cancer (NSCLC). The first patient received RC220 at 50 mg/m2 by intravenous infusion. No adverse events were observed.

HARNESS-1 is designed to test whether RC220, Racura’s proprietary formulation of (E,E)-bisantrene, can be safely combined with osimertinib (Tagrisso; AstraZeneca), a third-generation EGFR tyrosine kinase inhibitor (TKI) and standard-of-care therapy for EGFR-mutant NSCLC to delay or prevent TKI treatment resistance. Although EGFR TKIs have transformed outcomes for many patients with EGFR-driven lung cancer, acquired treatment resistance remains a central therapeutic challenge.

Daniel Tillett, Ph.D., Chief Executive Officer of Racura Oncology, said: "Dosing the first patient in HARNESS-1 is an important milestone for Racura and for the clinical development of RC220. The scientific rationale for this trial is grounded in the urgent need to address TKI therapeutic resistance in EGFR-mutant NSCLC. RC220 gives us the opportunity to explore whether targeting G4-DNA and RNA structures, including MYC-associated growth pathways, can delay EGFR TKI resistance arising and support a new therapeutic combination for patients treated with osimertinib. We are grateful to Associate Professor Surein Arulananda and the Monash Health team for enrolling and treating the first participant, and to the patients and families who make this research possible."

Scientific Rationale

EGFR-mutant NSCLC is a molecularly stratified lung adenocarcinoma subtype driven by constitutive EGFR kinase signaling and initial sensitivity to EGFR inhibition. However, responses to EGFR tyrosine kinase inhibitors, including osimertinib, are typically limited by acquired resistance, arising through heterogeneous mechanisms such as secondary EGFR alterations, bypass receptor tyrosine kinase activation, MAPK/PI3K pathway reactivation, oncogenic fusions, lineage plasticity, epithelial-to-mesenchymal transition and histologic transformation.

RC220 is being developed to target the non-canonical G-quadruplex DNA and RNA structures enriched in oncogenic regulatory regions, including promoters, untranslated regions and highly transcribed loci. Stabilization of these structures can disrupt transcriptional and post-transcriptional control networks that sustain malignant proliferation, including silencing the c-MYC-regulated growth and survival pathways.

HARNESS-1 is designed to evaluate the safety and tolerability of RC220 with continued osimertinib-mediated EGFR suppression, while generating pharmacokinetic, pharmacodynamic, molecular response and translational biomarker data.

HARNESS-1 Trial Design

HARNESS-1 is a multi-center Phase 1a/b clinical study in patients with EGFR-mutant NSCLC receiving osimertinib. The study includes an observational screening stage using ctDNA to help identify eligible patients and characterize tumor molecular status before treatment.

The Phase 1a dose-escalation stage will evaluate RC220 administered by intravenous infusion on Day 1 of each 21-day cycle in combination with standard-of-care maintenance osimertinib. The first three dose levels will use single-patient cohorts at 50 mg/m2, 100 mg/m2 and 150 mg/m2, before progressing to larger cohorts to identify the maximum tolerated dose and an appropriate dose for further study. Between 12 and 40 patients are expected to participate in the dose-escalation stage.

Following review of available safety and pharmacokinetic data, the study is expected to advance into a double-blind, randomized Phase 1b expansion stage. In this dose expansion stage, 40 patients will receive one of two RC220 dose levels in combination with osimertinib. Patients will be monitored for safety, pharmacokinetics and early signals of clinical activity, including progression-free survival, overall survival, ctDNA dynamics and changes in cancer-specific mutations.

The first patient was treated by Principal Investigator Associate Professor Surein Arulananda and his team at Monash Health in Clayton, Victoria. Additional clinical trial sites are expected to open in the coming months to support patient recruitment and study progress.

Clinical Trial Information

Further details about HARNESS-1, including open and recruiting sites, are available through the Australian and New Zealand Clinical Trial Registry at www.anzctr.org.au under trial code ACTRN12626000325303. Clinical trial inquiries may be directed to Racura Oncology at [email protected].

About RC220 & (E,E)-bisantrene

RC220 is a proprietary formulation of (E,E)-bisantrene designed to overcome drug solubility issues that prevent safe peripheral intravenous infusion. (E,E)-bisantrene, is a clinical validated small molecule anticancer agent that primarily functions via G4-DNA and RNA binding, leading to potent transcriptional silencing of the important cancer growth regulator c-MYC.
