Merck’s second-quarter 2026 results, released on August 4, came at an important time for the pharmaceutical company. With its flagship cancer immunotherapy KEYTRUDA facing eventual patent expiration later this decade, Merck has been pursuing a strategy to build a more diversified set of growth drivers. This quarter provided a useful snapshot of how that effort is translating into actual sales. The numbers also reflected the impact of the company’s recent deal-making, particularly the $6.8 billion acquisition of Terns Pharmaceuticals, so investors could assess whether near-term costs are being offset by operational strength and pipeline advancement. I also checked this using Tickeron’s AI Screener to see how the stock compares to others in the industry.
Merck reported worldwide sales of $16.6 billion for the second quarter of 2026, a 5% increase from $15.8 billion in the prior-year period, or 4% excluding foreign exchange effects. The top line came in above the analyst consensus of $16.41 billion.
On the bottom line, Merck recorded a non-GAAP loss of $0.13 per share. Although a loss, this result was notably better than the consensus estimate of a $0.27 loss per share. The GAAP loss was $0.54 per share, compared with a profit of $1.76 per share in the second quarter of 2025. Both GAAP and non-GAAP figures included a $2.31 per share charge related to the Terns Pharmaceuticals acquisition.
The KEYTRUDA family, including the subcutaneous formulation KEYTRUDA QLEX, generated $8.4 billion in sales, up 4% on a constant-currency basis. WINREVAIR, the treatment for pulmonary arterial hypertension, saw sales rise 75% to $588 million. WELIREG climbed 67% to $271 million. GARDASIL vaccine sales reached $1.17 billion, up 4%. Animal Health contributed $1.78 billion, an 8% increase.
Revenue from recently launched products, including WINREVAIR, KEYTRUDA QLEX, CAPVAXIVE, OHTUVAYRE, ENFLONSIA, and others, totaled $1.5 billion, more than doubling from $0.6 billion a year earlier. Non-GAAP gross margin was 81.1%, down 1.1 percentage points, mainly due to higher inventory reserves.
Merck shares rose approximately 1.4% in pre-market trading following the earnings release on August 4, showing investor approval of the revenue beat and the performance of newer products. The stock, which closed the prior session at $127.77, traded near the upper end of its 52-week range of $77.58 to $135.05, reflecting broader market confidence in the diversification strategy.
The post-earnings move was relatively measured. The reduction in full-year EPS guidance—from $5.04–$5.16 to $2.66–$2.76—was anticipated and primarily reflects the Terns acquisition charge rather than any operational shortfall. Investors appeared to focus on the underlying sales trajectory, pipeline progress, and the raised revenue forecast.
Looking ahead, Merck’s story will center on sustaining growth beyond KEYTRUDA. The company now guides for full-year 2026 revenue of $66.3 billion to $67.3 billion, implying 2% to 4% growth, and non-GAAP EPS of $2.66 to $2.76, a range that includes roughly $2.43 per share in total charges tied to the Terns deal.
Several potential catalysts are worth watching. The July FDA approval of LIPFENDRA (enlicitide), the first once-daily oral PCSK9 inhibitor for adults with hypercholesterolemia, opens a sizable cardiometabolic market. The Phase 3 readout for sac-TMT in advanced endometrial cancer met both overall survival and progression-free survival endpoints, marking the first positive pivotal data from the broad sac-TMT program that includes 17 ongoing Phase 3 trials.
In HIV, positive Phase 3 results were presented for the once-weekly oral regimen combining islatravir and lenacapavir (ISL/LEN), developed with Gilead. On the immunology side, tulisokibart met primary and key secondary endpoints in a Phase 3 ulcerative colitis induction study, though a separate trial in systemic sclerosis-associated interstitial lung disease was discontinued after missing its primary endpoint.
Operating expenses are now expected to reach $42.0 billion to $42.7 billion for the full year. Gross margin is projected around 81%. Investors should watch the pace of new product adoption, particularly LIPFENDRA’s early trajectory, along with further sac-TMT data and the competitive environment in oncology and vaccines.
