2. Investment Scenarios
Scenario 1: Steady Growth with Incremental Market Penetration
- Assumptions:
- CAGR of 3-5% driven by population growth.
- Strong adherence to guideline-prescribed metformin as first-line therapy.
- Limited patent expiry and generic competition.
- Financial Outlook:
- Moderna revenue estimate (2023): USD 1.8 billion globally (from branded and generic sales combined).
- Margins: Stable, given manufacturing simplicity and low-cost profile.
Scenario 2: Patent Expiry and Generic Market Expansion
- Assumptions:
- Patent expiry for branded formulations (e.g., Glucophage XR) in leading markets from 2024–2026.

- Financial Impact:
- Decreased revenue per unit (~USD 2-4 retail price for generics).
- Volume increase may compensate for margin erosion.
- Generics dominate the market, reducing branded drug revenues significantly.
Scenario 3: New Indications and Adjunctive Therapies
- Assumptions:
- Regulatory approval for additional indications: e.g., polycystic ovary syndrome (PCOS), cancer adjunct.
- Development of modified formulations (extended-release, combination pills).
- Potential anti-aging applications crossing regulatory hurdles.
- Potential Revenue Uplift:
- New indications could expand the market by 15-20%.
- Higher pricing for specialized formulations.
- Diversification buffer against generic erosion.
