TAM
Global prescription drug spending is projected to exceed $1.9 trillion by 2030, driven by oncology, immunology and cardiometabolic demand. Merck competes in the largest and fastest-growing therapeutic categories, but pricing pressure and patent cliffs shape the addressable opportunity.
RISK ASSESSMENT
HIGKeytruda patent cliff around 2028 could remove a large share of revenue and profit if pipeline/subcutaneous transition underdelivers.
MEDPricing pressure and IRA Medicare negotiation, plus Gardasil weakness in China, weigh on growth.
LOWFX and litigation/legal overhangs are manageable but persistent.
🐂 BULL
Keytruda franchise plus a deep oncology and cardiometabolic pipeline (including subcutaneous Keytruda and acquired obesity assets) can offset the 2028 patent cliff and drive mid-single-digit growth.
🐻 BEAR
Depressed trailing earnings (net margin 4%) and a 155x P/E reflect one-off charges and a looming Keytruda loss of exclusivity; if pipeline replacements disappoint, the stock is expensive on normalized earnings.
