Merck's Strategic Acquisition and Growth Potential: Analyst Upgrades Stock Rating to 'Buy'We rate MRK as Buy on valuation. In our view, the stock is too cheap for the growth it should be able to deliver on a near- and long-term basis, but admittedly, pending Keytruda competitor datasets in 2026, and Keytruda LOE in 2029 may continue to make investors apprehensive until additional solutions come through. MRK describes the 2029+ period as more of a “hill” versus a “cliff,” and our model shows the same. before it, should help make the description more believable to more investors. We raise our PO from $98 to $105, which is a 11x (vs 10x before) multiple on our unchanged 2026 EPS, given better long-term earnings visibility.
