Key Takeaways
- Merck stock is up 61% over the past year to $144 at the Oct 2 close, with the sharpest leg coming Aug 19 on the Phase 3 INTerpath-001 melanoma win.
- Scotiabank’s Sept 29 target hike to $180 from $155 sits 25% above the close.
- TIKR’s mid-case model values Merck at $166 by Dec 2030, implying 15% total return, or 3% annualized, from the $144 close, far below the 61% the stock just delivered.
Merck Stock Climbed 61% in a Year as Pipeline Readouts Came Early

Merck (MRK) stock has gained 61% over the past year, closing at $144 on October 2 after peaking above $155 in late August. The sharpest leg higher came on August 19, when Merck and Moderna reported that intismeran autogene plus Keytruda met its primary endpoint of recurrence-free survival in the Phase 3 INTerpath-001 melanoma trial.
The August 4 Q2 earnings call had already set the tone. Asked about the biggest risk to the $70 billion pipeline opportunity, CEO Rob Davis pointed to the pace of readouts: “So as we sit here today, my confidence is higher than it was in January because we are seeing meaningful derisking.” Four results since May back him up: sac-TMT’s survival win in endometrial cancer on May 18, tulisokibart’s Phase 3 pass in ulcerative colitis on June 22, the melanoma data, and tulisokibart’s September 30 hit in hidradenitis suppurativa, where 72% of patients on the top dose reached a 50% lesion reduction versus 35% on placebo.
The run has not been clean. Merck withdrew its ifinatamab deruxtecan filing for small cell lung cancer on September 25 after FDA discussions showed the Phase 2 data did not satisfy requirements for accelerated approval, and Merck stock has slipped from its August high. Growth is also cooling at the core: Keytruda family sales rose 5% to $8.4 billion in Q2, or 4% excluding foreign exchange, and CFO Caroline Litchfield told investors on September 9 that 2027 brings only modest top-line growth as new launches are partly offset by generic competition.
Still, Scotiabank raised its target to $180 from $155 on September 29, a level 25% above Friday’s close. Merck stock rose 61% as the pipeline built to support growth beyond Keytruda delivered several positive readouts, including some earlier than management had expected.
TIKR Values Merck Stock at $166, a 15% Gap After a 61% Run
TIKR’s mid-case model values Merck at $166 by December 2030, implying 15% total return from the current price of $144, or 3% annualized over 4.2 years.

Scotiabank’s $180 target sits 8-9% above that figure, which makes the model the more cautious voice on Merck stock.
A 3% annualized return leaves limited upside under TIKR’s mid-case assumptions after the stock’s 61% run. The path to $166 also comes as Merck expects only modest top-line growth in 2027, with new launches partly offset by generic competition and slowing Keytruda growth.
