How Will Eli Lilly's Oncology Drugs Perform in Q2 Earnings?

Read MoreHide Full Article

Key Takeaways

  • Oncology contributed over 15% of LLY's Q1 revenues, underscoring its importance to the company's growth.
  • Verzenio sales are likely to rise due to strong demand and higher realized prices despite currency pressures.
  • Declining Alimta and Cyramza sales may offset gains from Jaypirca and Retevmo amid rising competition.

Eli Lilly (LLY - Free Report) offers a diverse range of products that serve multiple therapeutic areas. While the company’s primary focus is on diabetes and obesity drugs, the oncology franchise also remains a key contributor to the top line. Sales from the oncology segment accounted for over 15% of Lilly’s first-quarter revenues, which grew more than 11% year over year.

Our model estimates second-quarter 2025 sales for the overall oncology unit to be $2.4 billion, indicating more than 11% year-over-year growth. A significant portion of these revenues is likely to have been generated from sales of the company’s blockbuster breast cancer drug, Verzenio. Sales of this drug are expected to have been driven by increased demand and higher realized prices during the quarter, partially offset by currency headwinds and competitive dynamics.

Sales of RET inhibitor Retevmo and newer lymphoma drug Jaypirca are also likely to have contributed positively to top-line growth during the quarter.

However, these gains might have been partially offset by the declining sales of older cancer drugs like Alimta and Cyramza, which are being impacted by competition from immuno-oncology agents in the United States.

Though Lilly’s oncology portfolio is contributing meaningfully, investor focus will largely remain on blockbuster GLP-1 medicines — Mounjaro (for type II diabetes) and Zepbound (for obesity). Investors will closely track their sequential growth and market share trends in the upcoming second-quarter results on Aug. 7.

Competition in the Oncology Space

Other bigger players in this area are AstraZeneca (AZN - Free Report) , Merck (MRK - Free Report) and Pfizer (PFE - Free Report) .

For AstraZeneca, oncology sales now account for nearly 41% of total revenues. Growth in AZN’s oncology franchise is being driven by medicines such as Tagrisso, Lynparza, Imfinzi, Calquence and Enhertu (in partnership with Daiichi Sankyo).

Merck’s key oncology medicines are PD-1 inhibitor, Keytruda and PARP inhibitor, Lynparza, which it markets in partnership with AstraZeneca. Keytruda, approved for several types of cancer, alone accounts for nearly half of Merck’s product revenues.

Pfizer’s oncology segment — comprising drugs like Xtandi, Lorbrena, the Braftovi-Mektovi combination and Padcev — currently accounts for more than 27% of its total revenues.
