Merck revenue falls after dramatic drop in sales of Covid antiviral treatment

Merck on Thursday reported first-quarter revenue that fell 9% from the same period a year ago largely due to a steep drop in sales of its Covid antiviral treatment molnupiravir. 

Sales of molnupiravir plunged to $392 million during the period, down 88% from the $3.2 billion reported in the first quarter of 2022. Merck said the decrease is primarily the result of lower sales in the U.S., U.K., Japan and Australia. 

The company reported total revenue of $14.5 billion during the quarter, down nearly $1.5 billion from the same period a year ago. But excluding the Covid drug, Merck said its revenue grew 11%. 

Here’s what Merck reported compared with Wall Street’s expectations, based on a survey of analysts by Refinitiv:

• Earnings per share: $1.40 adjusted, vs. $1.32 expected
• Revenue: $14.49 billion, vs. $13.78 billion expected

Merck’s stock rose more than 2% in premarket trading Thursday. Shares are up more than 2% for the year through Wednesday’s close, putting the company’s market value at nearly $288 billion.

The pharmaceutical giant posted a net income of $2.82 billion, or $1.11 per share. That compares with a net income of $4.31 billion, or $1.70 per share, for the same period a year ago. Excluding certain items, Merck’s adjusted earnings per share were $1.40 for the period. 

The Rahway, New Jersey-based company is now forecasting 2023 sales of $57.7 billion to $58.9 billion, slightly higher than the $57.2 to $58.7 billion guidance provided in early February. The lifted guidance includes approximately $1 billion in sales of molnupiravir.

The company also raised its full-year adjusted earnings outlook to $6.88 to $7.00 per share, from a previous forecast of $6.80 to $6.95 per share.

The forecast does not reflect any financial impact from Merck’s proposed acquisition of biotech company Prometheus Biosciences earlier this month, the company noted. Merck said that deal is expected to close in the third quarter of 2023.

Merck’s molnupiravir treatment first entered the market after the Food and Drug Administration authorized the pill for certain adults in December 2021. Once hailed as a game-changing treatment for Covid-19, Merck signed several contracts to supply millions of courses of the drug to the U.S. government and other nations. 

But Merck and drugmakers such as Pfizer, Moderna and Johnson & Johnson have been bracing for a drop-off in Covid-related sales this year as the world emerges from the pandemic and relies less on blockbuster vaccines and treatments. 

Molnupiravir weighed on sales for Merck’s pharmaceutical business, which declined 10% to $12.7 billion compared with the first quarter of 2022. Excluding molnupiravir, pharmaceutical sales grew 14%. 

Merck said diabetes treatments also drove the sales decrease. Sales of sitagliptin and a similar diabetes treatment fell 29% to $880 million during the quarter, primarily due to generic competition in several international markets and lower demand and pricing in the U.S.

But Merck’s pharmaceutical unit saw higher sales of the blockbuster antibody treatment Keytruda, which increased 20% to $5.8 billion during the quarter. Keytruda is used against several types of cancer, including certain types of breast cancer and skin cancer. 

Sales of Gardasil, Merck’s vaccine that prevents cancer from HPV, also grew 35% to $2 billion. The company said the growth reflects strong demand outside of the U.S., particularly in China. 

Merck will hold an earnings conference call at 9:00 a.m. ET.
