What does Merck & Co. do?

Merck & Co. is a globally active pharmaceutical company based in the US. The company develops, produces and markets prescription medicines and vaccines for human health as well as animal health products. The focus is on oncology, vaccines, infectious diseases, cardiovascular diseases and hospital medicines. The best-known brands include the PD-1 antibody Keytruda, the HPV vaccine series Gardasil, and products such as Welireg, Winrevair and Bridion.

Merck generates revenue mainly from wholesalers, pharmacies, hospitals, healthcare systems and government vaccination programs. The pharmaceutical business is complemented by the animal health division, which serves livestock, companion animals and aquaculture. In competition, Merck is among the largest research-based drugmakers worldwide and competes with companies such as Pfizer, Bristol Myers Squibb, Roche and AstraZeneca. Its position is based on an extensive research pipeline, patent protection, regulatory expertise and global distribution structures. At the same time, earnings are strongly tied to individual blockbuster products. Confusion with the German Merck KGaA should be avoided, as they are separate companies.

What the business depends on

  • Revenue depends largely on the success of a few high-selling drugs, particularly in oncology.
  • New approvals, indication expansions and successful clinical trials secure the long-term supply of patent-protected products.
  • Vaccine demand and government vaccination recommendations shape growth in the vaccine division and the utilization of production.

Risks

  • The expiration of patents leads to generic and biosimilar competition and can put significant pressure on major revenue contributors.
  • Price regulation, negotiations with government programs and political intervention in drug pricing weigh on margins.
  • Failures in clinical trials or approval procedures can impair the value of high research investments and weaken the pipeline.

What to look for with Merck & Co.

The share of the top-selling product in total revenue shows the dependence on individual blockbusters and thus the risk at patent expiration.
