How to Play LLY Stock as Zepbound Beats NVO's Wegovy in Obesity Study

Eli Lilly and Company announced earlier this week that its popular obesity drug, Zepbound (tirzepatide) outperformed rival Novo Nordisk’s Wegovy (semaglutide) in a weight-loss head-to-head study.

In the phase IIIb 72-week study, Zepbound led to an average weight loss of 20.2% of body weight in obese or overweight adults, compared to 13.7% for Wegovy, representing a 47% greater relative weight loss for Zepbound users.

In the study, Zepbound showed superior results across the primary endpoint and all five key secondary endpoints, and its safety profile was consistent with previous studies.

The latest Zepbound data bodes well for Lilly. It can help drive market share and potentially establish the drug as the new standard for obesity medications.

Lilly markets tirzepatide as Zepbound for obesity and as Mounjaro for type II diabetes. Though demand for the two drugs remains massive, Mounjaro and Zepbound’s sales were hurt due to inventory issues in the third quarter. This led the shares of the company to drop after third-quarter results after a powerful first-half performance. However, it looks like the stock is back on investors’ radar with the latest positive Zepbound data.

Let’s understand the company’s strengths and weaknesses to better analyze how to play the stock after the latest news.

Mounjaro & Zepbound: Key Top-Line Drivers for Lilly

Tirzepatide is a dual GIP and GLP-1 receptor agonist (GIP/GLP-1 RA). The GLP-1 segment is a very important class of drugs for multiple cardiometabolic diseases and is gaining significant popularity.

Despite a short time on the market, Mounjaro and Zepbound have become key top-line drivers for Lilly in 2024, with demand rising rapidly. Mounjaro and Zepbound generated sales of $11.0 billion in the first three quarters of 2024, accounting for around 45% of the company’s total revenues.

However, the quarter-over-quarter growth of Zepbound and Mounjaro in 2024 has been impacted by supply and channel dynamics. In the second quarter, increased supply led to higher shipments, which allowed the company to fulfill all backorders for its wholesales. However, channel inventory decreased at wholesalers in the third quarter, which hurt sales of the drugs. It is difficult to predict the demand/inventory dynamics of these products with the potential for lumpiness in channel stocking.
