Merck is a mature cash-generator currently heavily reliant on its blockbuster oncology drug Keytruda and the Gardasil vaccine franchise. While near-term cash flows and dividend safety are robust, the long-term investment thesis hinges on management's ability to successfully commercialize its pipeline of Antibody-Drug Conjugates (ADCs) and leverage M&A to offset the massive patent cliff approaching in 2028. Fair value range: low $94.9, high $147, with mid-point at $121.

§2 Cas baissier
A severe stress test assumes structural earnings decline post-2028 as Keytruda revenues drop, combined with a failure to realize ADC revenue and M&A integration issues, compressing gross margins.
