ROME and CORAL GABLES, Fla., July 16, 2026 (GLOBE NEWSWIRE) -- Angelini Pharma S.p.A. ("Angelini Pharma"), international pharmaceutical company and part of Angelini Industries, announces today the completion of its acquisition of Catalyst Pharmaceuticals, Inc. ("Catalyst") (Nasdaq: CPRX). Catalyst is now part of Angelini Pharma, integrating Catalyst’s portfolio and commercial infrastructure with Angelini Pharma's expertise and products in Brain Health.

The transaction provides the participation of funds managed by Blackstone, that will invest 1 billion euros in preferred equity, subject to customary regulatory clearances.

CDP Equity has approved to invest around 1 billion euros through a capital increase to acquire a 23.5 per cent stake in the common equity of Angelini Pharma. The investment, strongly supported by CDP Equity, underpins Angelini Pharma’s transformation into a global player in brain health and rare diseases. It accelerates its expansion into the US market through the acquisition of Catalyst and promotes a significant increase in investments in research and development, thereby strengthening the entire national pharmaceutical sector and fostering high-quality employment growth in Italy as well.

The operation was financed with the support of BNP Paribas, acting as Sole Global Coordinator and Underwriter of the overall financing package, including the bridge-to-equity, for Angelini Pharma. Morgan Stanley & Co. International plc is acting as sole financial advisor to Angelini Pharma in connection with the participation of Blackstone and CDP Equity.

This acquisition marks a pivotal moment in the ongoing transformation journey that Angelini Industries — a company with more than 100 years of history – has been pursuing with a clear strategic vision over the past four years and establishes Angelini Pharma's presence in the U.S. as part of a balanced growth strategy, that will continue to see Italy as a strategic reference hub for production and scientific research within the Group's global operations.

Sergio Marullo di Condojanni, CEO of Angelini Pharma, said: “With the completion of this transaction, Angelini Pharma takes a decisive step to become a global player, increasingly driven by science and guided by a patient-centric vision, with a growing focus on Brain Health and Rare Disease. Expanding the U.S. market, combined with Catalyst's portfolio and expertise in rare neurological diseases, allows us to gain the scale needed to build a next-generation therapeutic platform in Brain Health and Rare Disease, while continuing to strengthen our core business in Europe, where our industrial presence in Italy remains a strategic asset for the Group. I want to extend a warm welcome to Rich and to the entire Catalyst team joining Angelini Pharma: I am thrilled by the opportunity to build something ambitious together, and I look forward to working closely as we shape the future of this platform, with patient care always at the center of our vision. Finally, I would like to thank Blackstone and CDP Equity for their trust and for their valuable contribution as partners in this transformative phase for the Group.”

Rich Daly, President, Global Rare Disease Business Unit Angelini Pharma: “We are honoured to become part of the long-standing, strong legacy of Angelini Pharma. Today marks a significant day for all of our important stakeholders - especially patients living with rare diseases, their caregivers, and our employees as we create an impressive new global scale with the goal to continue to bring new treatments to people globally. As the newly formed Global Rare Disease Business Unit of Angelini Pharma, we look forward to working together to make a meaningful difference.”

Fabio Barchiesi, Ceo of CDP Equity, said: “This investment is a concrete example of the role that CDP Equity intends to play in supporting the country’s economic ecosystem. Our investment targets a sector that embodies Italian excellence with high growth potential and supports a national champion in its journey from a predominantly Italian and European operator to a player of global significance. The transaction is consistent with our commitment to supporting the drive for innovation and the international growth of Italy’s industrial excellence. These objectives have, in fact, been identified in CDP Equity’s Strategic Plan as key drivers for the competitiveness, strategic autonomy and economic security of our production sector”.

Andrea Valeri, Chairman of Blackstone Italy, said: “We are pleased to support one of Italy’s leading companies in this transformative acquisition, leveraging Blackstone’s global franchise and deep expertise in life sciences,” and Craig Shepherd, Senior Managing Director, Blackstone Life Sciences, added: “Blackstone sees compelling opportunities to provide capital solutions at scale to biopharmaceutical companies and we are thrilled to back Angelini Pharma’s continued growth and strategic goals.”
