BofA Securities analyst Jason M. Gerberry reiterated a Buy rating and $132.00 price target on Merck (NYSE: MRK)

The analyst commented, "This morning, MRK announced a definite agreement to acquire Terns Pharmaceuticals (TERN) for a total transaction value of ~$6.7bn ($5.7bn net of cash). MRK will take a ($5.8bn)/($2.35 per share) IPR&D charge in 2Q. The lead product is TERN-701 (Ph3 nearly ready), an allosteric modulator (myristate pocket) of BCR-ABL for CML. Merck sees ‘701 as a drug with multi-bn peak sales potential. In our view, the TERN deal adds to a string of 2025 deals (Cidara, Verona) that provide highly de-risked drugs with multi- $bn peak sales, with growth expected sometime during the Keytruda LOE period (2029- 31 range). Consistent with our thesis, MRK looks well positioned to mitigate the Keytruda LOE and potentially even grow through that event based on pending 2026-27 portfolio developments (data catalysts, launches, and M&A) – this is important because the LOE is the primary reason for MRK’s discounted stock multiple. We maintain our Buy rating on commercial and pipeline diversification catalysts a driving re-rating. We do not include the TERN deal in our model, pending 2Q26 deal close."
