Management Comments

• "We have made significant progress this year advancing our global Phase 3 program evaluating the regimen of bemnifosbuvir/ruzasvir for the treatment of HCV. Global patient enrollment is on track in both C-BEYOND and C-FORWARD trials." Jean-Pierre Sommadossi, PhD, Chief Executive Officer and Founder of Atea.
• "We are focused on the successful development of a potential best-in-class HCV regimen to treat and cure todays patients infected with HCV." Jean-Pierre Sommadossi, PhD, Chief Executive Officer and Founder of Atea.
• "Based on results to-date, we believe that the profile of our regimen, which includes a short treatment duration, low risk for drug-drug interactions and convenience with no food effect, is particularly well suited for the test-and-treat model and has the potential to help advance HCV elimination in the US and globally." Dr. Sommadossi.

Industry Context

HCV remains a significant global health burden with 2.4 to 4.0 million people in the US and an estimated 50 million worldwide infected, and approximately one million new infections annually. Despite existing direct-acting antivirals (DAAs), diagnoses outpace cure rates in the US. Healthcare providers seek new treatment options with high efficacy, short duration, and low drug-drug interaction risk, especially since up to 80% of HCV patients take multiple medications for comorbidities. Atea's regimen aims to address these unmet needs and advance HCV elimination.

Comparison to Industry Standards

• Atea's bemnifosbuvir/ruzasvir regimen is being compared to the fixed-dose combination of sofosbuvir/velpatasvir in Phase 3 trials.
• The bemnifosbuvir/ruzasvir regimen is administered orally once-daily for 8 weeks (non-cirrhotic patients) or 12 weeks (compensated cirrhotic patients), potentially offering a shorter treatment duration for a significant patient population compared to sofosbuvir/velpatasvir, which is administered for 12 weeks to all patients.
• Phase 2 results for bemnifosbuvir/ruzasvir showed a robust 98% SVR12 in the Per-Protocol Treatment-Adherent Population (n=215) and 95% SVR12 in the Per-Protocol Regardless of Adherence Population (n=259), indicating high efficacy comparable to leading DAAs.
• The regimen's profile includes a low risk for drug-drug interactions and no food effect, which are significant advantages for patient convenience and adherence, particularly for HCV patients who often manage multiple comorbidities and coinfections.
• Bemnifosbuvir can be used without dose adjustment in patients with hepatic or renal impairment, including those undergoing dialysis, which broadens its applicability compared to some existing treatments that may require dose adjustments or be contraindicated in these populations.

Management Changes

Corporate Governance

Stakeholder Impact

• Shareholders: Potential for increased value through share repurchase and strategic alternatives review; positive clinical trial progress could lead to future revenue.
• Patients with HCV: Potential for a new, highly effective, convenient, and well-tolerated treatment option with a shorter duration and fewer drug-drug interactions.
• Healthcare Providers: A new treatment option that could facilitate "test-and-treat" models and address the needs of a changing patient population with comorbidities.
• Employees: Continued focus on the HCV program and strategic review could impact future organizational structure, but current progress is positive.

Next Steps

• Continue patient enrollment in global Phase 3 C-BEYOND and C-FORWARD trials for HCV.
• Successful development of the bemnifosbuvir/ruzasvir regimen.
• Completion of the strategic alternatives review process with Evercore.

Key Dates

Recommendation

While the clinical progress for the HCV program is very positive, showing strong efficacy and a favorable profile, and the company is actively pursuing shareholder value through a share repurchase and strategic review, the company is still in the clinical stage with significant cash burn. The strategic review introduces uncertainty regarding the company's future structure. The decrease in cash reserves, while expected for a clinical-stage company, warrants a cautious approach. The stock repurchase is a positive signal, but the overall financial position still reflects a development-stage company. Investors should hold to see the outcome of the Phase 3 trials and the strategic review.
