In This Article:

GREENFIELD, Ind., May 5, 2025 /PRNewswire/ -- Elanco Animal Health Incorporated (NYSE: ELAN) today announced the sale of certain future tiered royalties and commercial milestones associated with XDEMVY® (lotilaner ophthalmic solution) 0.25%, for the human health application of lotilaner, to funds affiliated with Blackstone Life Sciences and Blackstone Credit & Insurance for $295 million in cash. Monetization of this non-core asset will be used to accelerate debt reduction, positioning Elanco to achieve an expected net leverage ratio of 3.9x to 4.3x adjusted EBITDA by the end of 2025. Elanco will repay portions of its outstanding term loans on a pro-rata basis, which is expected to reduce interest expense by approximately $10 million, offset by the sale of approximately $10 million of royalties based on Elanco's initial 2025 guidance.

In 2019, Elanco exclusively licensed lotilaner to Tarsus Pharmaceuticals, Inc. (NASDAQ: TARS) for exploration as a solution to several unmet human health needs. In 2023, XDEMVY became the first lotilaner-based product approved for human use and the only FDA-approved medicine for treatment of Demodex blepharitis (DB), a common eyelid disease in humans caused by Demodex mites.

"Elanco's team of scientific experts is focused on identifying and developing molecules to generate high-impact innovation, not just in our own portfolio, but in adjacent industries to create broader value," said Jeff Simmons, Elanco President and CEO. "As we continue to focus on launching our recent innovation and accelerating our core business sales growth in 2025, this transaction delivers incremental cash that advances our deleveraging goals making high 3x net leverage a real possibility by the end of 2025. We appreciate Blackstone's collaborative investment to further Elanco's goals and their recognition of the positive potential impact of XDEMVY on millions of DB patients in the U.S."

"Elanco's innovation served as the basis for XDEMVY's strong efficacy and safety profile, and Tarsus' executional strength has led to its rapid adoption and commercial success. We are pleased to partner with both leading pharmaceutical companies and back this first-in-class treatment that addresses a pervasive and damaging eyelid disease," said Craig Shepherd and Kiran Reddy, MD, Senior Managing Directors, Blackstone Life Sciences.

The agreement applies to certain tiered royalties associated with the U.S. net sales of XDEMVY from April 2025 through August 2033 and certain commercial milestones. Elanco retains the rights to all royalty payments on net sales outside the U.S. as well as any future human applications of lotilaner beyond ophthalmic solutions.
