What has Merck guided for the year?

Management’s August 4 outlook calls for sales of $66,300–$67,300 million and non-GAAP earnings per share, or adjusted profit per share, of $2.66–$2.76. Merck still includes major charges for acquired research assets in that adjusted result, so buying future medicines can hurt earnings before those medicines produce sales.

Has Merck kept its past promises?

Merck delivered 2025 revenue within its public forecast range, but its internal bonus targets used a different yardstick and were missed. Manufacturing and organizational savings promised for the end of 2027 remain unfinished. The fairest conclusion is that Merck has meaningful mechanisms for alignment, but managers still need to prove that scientific milestones become successful launches, cost reductions protect supply, and shareholder returns improve.

How have Merck's revenue and profit trended?

Q2 2026 showed resilient sales and better cash flow, but weaker margin quality beneath the acquisition-driven loss. Revenue grew about 5.1% year over year, and Merck reported about 4% growth excluding currency.

What should investors watch in Merck's next results?

October 29’s third-quarter results should clarify SciBrunch’s full-year effect and the underlying launch trend. OHTUVAYRE is especially important because an inventory unwind could weaken shipments without weakening patient use. KEYTRUDA QLEX adoption will show whether easier administration leads to repeat treatment and reimbursement.

From the full memo · 1. The business

Merck & Co. sells treatments, vaccines, and animal-health products, but its business is easier to understand as a chain than as a catalogue. A patient, pet owner, farmer, clinic, insurer, wholesaler, or public programme creates demand; Merck turns that demand into net sales, then spends the proceeds on science, production, partners, and the company itself.
