Executive Summary

Gilead Sciences is a biopharmaceutical company focused on developing and commercializing antiviral drugs, primarily for HIV, viral hepatitis, and oncology. Revenue is generated through the sale of patented drugs, facing eventual generic competition. Gilead's economic quality is high when protected by patents and regulatory exclusivity, delivering strong cash flows, but declines sharply upon patent expiration. The competitive edge resides in its R&D capabilities, which are essential for replenishing its drug pipeline. Risks include clinical trial failures, regulatory hurdles, and the unpredictable nature of pharmaceutical innovation. Capital allocation decisions, including acquisitions and share repurchases, significantly influence long-term shareholder returns. Gilead is a business that relies on consistent drug innovation and patent protection to sustain profitability.

1. What They Sell and Who Buys

Gilead sells antiviral therapies to patients, hospitals, and government health agencies. Its primary products target HIV, hepatitis B, hepatitis C, and various cancers.

2. How They Make Money

Revenue is generated from the sale of pharmaceutical products, priced based on efficacy, market demand, and competitive alternatives, primarily through insurance reimbursement models.

3. Revenue Quality

Revenue quality is high during patent protection, characterized by recurring prescriptions. Post-patent expiration, revenue declines as generics erode market share.

4. Cost Structure

The cost structure includes R&D, manufacturing, sales, and administrative expenses. R&D is the largest discretionary expense, essential for future revenue generation. Manufacturing costs are moderate, benefiting from economies of scale.

5. Capital Intensity

The business is moderately capital intensive, requiring investments in manufacturing facilities and ongoing R&D.

6. Growth Drivers

Growth drivers include the development and successful commercialization of new drugs, expansion into new therapeutic areas (e.g., oncology), and geographic expansion.

7. Competitive Edge

Gilead's competitive edge lies in its intellectual property (patents), R&D expertise, and established relationships with healthcare providers and regulatory agencies.

8. Industry Structure and Position

The biopharmaceutical industry is oligopolistic, with a few major players dominating key therapeutic areas. Gilead holds a significant position in antiviral therapies.

9. Unit Economics and Key KPIs

Key KPIs include the number of prescriptions, average selling price per unit, patent expiration dates, R&D success rates, and clinical trial outcomes.

10. Capital Allocation and Balance Sheet

Capital allocation is focused on R&D, acquisitions, and returning capital to shareholders through dividends and share repurchases. The balance sheet carries moderate debt, used strategically for acquisitions.

11. Risks and Failure Modes

Risks include clinical trial failures, regulatory setbacks, patent expirations, competition from generics, and pricing pressures from healthcare payers.

12. Valuation and Expected Return Profile

Valuation depends on pipeline prospects and future earnings potential. Expected returns are linked to successful R&D and efficient capital allocation.

13. Catalysts and Time Horizon

Catalysts include positive clinical trial results, FDA approvals, strategic acquisitions, and patent extensions. The time horizon for realizing returns is medium to long term, reflecting the drug development cycle.
