BURLINGAME, Calif. – July 31, 2024 – Innoviva, Inc. (NASDAQ: INVA) (“Innoviva” or the “Company”), a diversified holding company with a core royalties portfolio, a leading critical care and infectious disease platform known as Innoviva Specialty Therapeutics (“IST”), and a portfolio of strategic investments in healthcare assets, today reported financial results for the second quarter ended June 30, 2024, and highlighted select corporate achievements.

“Our robust second quarter continues to demonstrate the successful transformation of Innoviva. We have strong performance across multiple fronts, driven by our core GSK royalties portfolio and accelerating growth from our commercial products, GIAPREZA^®, XACDURO^® and XERAVA^®,” said Pavel Raifeld, Chief Executive Officer of Innoviva. “We remain committed to enhancing shareholder value through thoughtful capital allocation and operational excellence. We also are excited about our portfolio of strategic healthcare assets, where we continue to see potential for significant value creation.”

Mr. Raifeld added, “In addition to driving strong operational delivery from our critical care and infectious disease platform IST, we continue to expand its global footprint and enhance recognition. Our partner in China, Zai Lab, successfully obtained regulatory approval for XACDURO^®, bringing us closer to making XACDURO^® available to all patients globally. In the U.S, important treatment guidelines and guidance updates recognized our key products, underscoring their life-saving potential. XACDURO^® was named the preferred agent for treatment of Carbapenem-resistant Acinetobacter baumannii infections in the 2024 Infectious Diseases Society of America (IDSA) treatment guidance. XERAVA^® is recommended by the 2024 Surgical Infection Society (SIS) treatment guidelines for empiric therapy in the management of complicated intra-abdominal infection.”
