ESTABLISHED FDA APPROVED PRODUCT TO ITS COMMERCIAL PORTFOLIO

Cumberland to expand its gastroenterology offerings

with the market-leading Helicobacter pylori therapy

NASHVILLE, Tenn., (Oct. 20, 2025) – Cumberland Pharmaceuticals Inc. (Nasdaq: CPIX), a specialty pharmaceutical company focused on delivering high-quality products to improve patient care, announced strategic arrangements with RedHill Biopharma Ltd. (Nasdaq: RDHL), a specialty biopharmaceutical company, to jointly commercialize Talicia®. The FDA-approved oral capsule is indicated for the treatment of Helicobacter pylori infection in adults, a bacterial infection and leading risk factor for gastric cancer.

Under the terms of the agreement, Cumberland and RedHill will form a new, jointly owned company. RedHill will contribute all its Talicia assets to the new company, including the product’s growing international licenses with associated revenues. Cumberland will provide $4 million in investment capital. Cumberland will assume responsibility for the product’s distribution and record the product sales. Talicia net revenues were $8 million in 2024. The two companies will equally share in those net revenues and collaborate on all operational aspects, including sales, marketing, manufacturing, regulatory and supply chain functions. Through this co-commercialization agreement, Cumberland will leverage its established national field sales force to lead promotional efforts for Talicia and expand its reach among office-based healthcare providers.

“Talicia features an outstanding clinical profile and represents an excellent strategic match for our organization,” said A.J. Kazimi, CEO of Cumberland Pharmaceuticals. “It provides us with an immediate growth opportunity, as we will build on the excellent foundation RedHill has created and bring this critical therapy to many more patients.”

Talicia is the only all-in-one treatment containing omeprazole, amoxicillin and rifabutin. It was FDA approved based on two large Phase 3 studies demonstrating excellent safety and efficacy results. The product features include three key advantages: 1) high eradication rates at >90%, 2) simplicity of an all-in-one capsule and 3) low resistance.

As a result of these attributes, Talicia is now listed as a first line option in the newly updated American College of Gastroenterology guidelines for the treatment of H. pylori infections.

“These arrangements represent an excellent opportunity for Cumberland, a highly capable and driven partner with a strong gastroenterology market presence, to add a market-leading approved product to its portfolio,” said Rick Scruggs, Chief Commercial Officer of RedHill Inc. We believe Cumberland can help drive prescriptions and deliver revenue growth, further strengthening Talicia’s U.S. market leadership.”

The product is patent protected through 2042 and received eight years of U.S. market exclusivity under its Qualified Infectious Disease Product (QIDP) designation.

There is broad U.S. insurance coverage established for the product with includes 70% of American lives covered by commercial plans and 60% coverage by government plans.
