## Customers

Merck sells human health products mainly to drug wholesalers, retailers, hospitals, government agencies, and managed care organizations such as HMOs and PBMs. Its vaccines are purchased by physicians, distributors, wholesalers, and government entities, while Animal Health serves veterinarians, distributors, livestock producers, farmers, and pet owners. Pricing, formulary access, and reimbursement are important because many end customers are intermediated by payers and public programs.

- **Wholesalers and retailers** (primary) — Buy prescription medicines in bulk for downstream distribution and are central to Merck's U.S. channel economics and chargeback/rebate structure.
- **Hospitals and managed care organizations** (primary) — Purchase or influence access to branded therapies and vaccines through formularies, reimbursement, and contracting decisions.
- **Government and public health buyers** (secondary) — Buy vaccines and certain medicines through public programs and procurement channels, especially in the U.S. and abroad.
- **Veterinarians and animal producers** (secondary) — Buy animal health medicines, vaccines, and monitoring solutions to prevent and treat disease in livestock and companion animals.
- **Pet owners and companion animal channel** (emerging) — Purchase selected animal health products through veterinary and retail channels for preventive and therapeutic care.

- Drug wholesalers and retailers that distribute prescription medicines
- Hospitals and health systems that buy branded therapies and vaccines
- Managed care organizations and PBMs that influence formulary access
- Government agencies and public programs that purchase vaccines and drugs
- Veterinarians, farmers, and pet owners buying animal health products

## Geography

Merck is a global business with operations across the U.S., Europe, Latin America, the Middle East, Africa, Eastern Europe, and Asia Pacific. The company highlights growth opportunities in developing markets, but those regions also add exposure to currency swings, regulation, and political instability. Manufacturing and development activity is also international, including the Dundalk, Ireland facility acquired in 2025.

- U.S. is the core commercial market and major source of pricing pressure
- Europe is important for sales, manufacturing, and regulatory access
- Asia Pacific and emerging markets support long-term growth
- Latin America, Middle East, Africa, and Eastern Europe add expansion upside
- Ireland is a notable manufacturing footprint after the Dundalk facility deal

## Strategy

Merck's strategy centers on science-led growth through internal R&D, new product approvals, and external business development. The company is prioritizing oncology, cardiometabolic, respiratory, ophthalmology, and immunology programs while continuing to defend and extend key franchises such as vaccines and animal health. Capital allocation remains balanced between pipeline investment, acquisitions/licensing, dividends, and share repurchases.

- **Advance the pipeline in oncology, cardiometabolic, respiratory, and immunology** (medium-term) — Merck needs new products to offset patent expirations, pricing pressure, and declining mature franchises.
- **Use business development to supplement internal R&D** (short-term) — External assets can accelerate growth and diversify the portfolio when internal discovery alone is insufficient.
- **Defend access and pricing in the U.S. market** (short-term) — Rebates, chargebacks, formulary placement, and government pricing materially affect realized net sales.
- **Maintain shareholder returns while funding growth** (medium-term) — Merck uses operating cash flow to support dividends, repurchases, and strategic investments.

- Invest in late-stage and early-stage pipeline to replace maturing products
- Expand oncology and cardiometabolic franchises with new launches and data
- Use licensing and acquisitions to add external science and assets
- Support animal health and vaccines as diversified growth engines
- Return capital through dividends and buybacks while funding R&D

## Risks

Merck's biggest risks come from patent expiry, pricing pressure, and dependence on a small number of large products that generate a disproportionate share of profit and cash flow. The company also faces regulatory, litigation, and R&D execution risk, while its global footprint exposes it to FX, tax, geopolitical, and supply-chain issues. In Animal Health, competition and product-cycle risk are similar, but the commercial channels and end markets differ.

- **Patent expiration and generic/biosimilar competition** [high] — Merck relies on patent protection to preserve exclusivity; once lost, sales can fall quickly.
- **Pricing pressure and formulary access** [high] — Rebates, chargebacks, government pricing, and managed care negotiations lower realized prices.
- **R&D and clinical development failure** [high] — Pipeline assets may not achieve approval or commercial success, leaving gaps after mature products decline.
- **Regulatory and litigation risk** [medium] — Product liability, antitrust, patent disputes, and government investigations can block sales or create charges.
- **Foreign exchange and geopolitical exposure** [medium] — International sales and operations create volatility from currency moves, local regulation, and political instability.

- Patent loss can trigger rapid sales erosion when exclusivity ends
- Key products are concentrated sources of profit and cash flow
- U.S. pricing pressure and rebate growth reduce realized net sales
- R&D and regulatory setbacks can delay or eliminate future growth
- Global operations add FX, tax, political, and supply-chain exposure

## Accounting

Merck's reported results are heavily affected by estimates for rebates, chargebacks, returns, and government pricing, which can change with channel inventory and patient usage. Acquisition accounting, intangible asset valuation, milestone payments, restructuring charges, and impairment testing also matter because they can move earnings materially without changing underlying demand. The company also has meaningful seasonality and quarter-to-quarter variability from product mix, collaboration payments, and tax timing.

- **Revenue deductions for rebates, chargebacks, and returns** — Net revenue and quarterly comparability
- **Acquisition accounting and intangible valuation** — Amortization, impairment risk, and earnings volatility
- **Milestone and upfront collaboration payments** — Period earnings and cash flow timing
- **Restructuring and accelerated depreciation** — Operating margin and comparability
- **Impairment of goodwill and long-lived assets** — Non-cash charges and asset values

- Sales discounts, rebates, and chargebacks affect reported net revenue
- Acquisition fair values for IPR&D and intangibles drive future amortization
- Milestone and upfront collaboration payments can create large period charges
- Restructuring and accelerated depreciation affect operating margins
- Goodwill and intangible impairment risk is tied to product performance
