Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) and Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX), a global pharmaceutical company focused on the discovery, development and commercialization of novel therapeutics for endocrine diseases,  announced that the companies have entered into a definitive agreement under which Vertex will acquire Crinetics for $85.00 per share in cash, for a total equity value of approximately $10.0 billion, or approximately $8.8 billion net of estimated cash acquired. The transaction was unanimously approved by both the Vertex and Crinetics Boards of Directors and is anticipated to close in the third quarter of 2026.

Crinetics’ marketed medicine, PALSONIFY^® (paltusotine), received approval from the U.S. Food and Drug Administration (FDA) in September 2025. PALSONIFY was recently approved by the European Medicines Agency (EMA) and is under review by other global regulatory bodies. It is the first and only once-daily oral therapy for adults with acromegaly, a rare and debilitating condition caused by a pituitary tumor that secretes excess growth hormone, which affects an estimated 20,000 diagnosed people in the U.S. PALSONIFY leads to rapid disease control and normalization of key disease markers in both treatment-experienced and untreated populations. Since launch, PALSONIFY has demonstrated promising early commercial momentum, supported by strong demand across all patient segments, prescribing activity expansion, and growing reimbursement coverage, all of which reinforce its potential to redefine the treatment paradigm in acromegaly.

Crinetics' most advanced pipeline candidate, atumelnant, is a once-daily oral adrenocorticotropic hormone (ACTH) receptor antagonist currently in Phase 3 development for congenital adrenal hyperplasia (CAH). Classic CAH, the most severe form of the disease, with 17,000 addressable patients in the U.S., is a rare, chronic genetic condition affecting the adrenal glands that has significant unmet medical need. Among other features, CAH is characterized by impaired cortisol synthesis and, in most cases, excess androgen production, both of which contribute to a range of serious health consequences. In Phase 2 studies, patients taking atumelnant were able to achieve near normalization of excess androgen levels on physiologic replacement doses of glucocorticoids. This unique therapeutic profile positions atumelnant to become the leading medical therapy for people struggling with CAH. Atumelnant was generally well tolerated with no treatment-related severe or serious adverse events to date.

“Crinetics is an excellent strategic fit for Vertex, with its focus on serious diseases in specialty markets with significant unmet need, well-understood causal human biology, and potentially best-in-class medicines that could deliver transformative benefit to patients,” said Reshma Kewalramani, M.D., Chief Executive Officer and President of Vertex. “We believe Vertex can build on the strong momentum of the PALSONIFY launch by applying our experience in commercializing medicines for rare genetic diseases. We are also excited by the significant potential of atumelnant to transform the treatment landscape for CAH, setting a new standard of care where patients do not have to choose between managing their excess adrenal androgens and enduring the side effects of high-dose steroids.”

Dr. Kewalramani continued, “We look forward to working with the talented Crinetics team to rapidly advance their pipeline of medicines for patients living with serious, rare endocrine disorders. Together, these potential blockbuster assets build on our core CF business, ongoing launches and internal innovation portfolio, adding to our growth outlook and driving value for patients and shareholders.”

“Nearly 18 years ago, we founded Crinetics with a clear goal of transforming the lives of patients living with endocrine-related diseases. Today marks a historic milestone as we embark on this next chapter with Vertex,” said Scott Struthers, Ph.D., Founder and Chief Executive Officer of Crinetics Pharmaceuticals. “This partnership is anchored by a mutual commitment to science and a shared vision for delivering innovative treatments to patient communities that have long been underserved. Vertex’s global infrastructure and commercial footprint will serve to amplify the reach of our science and allow us to maximize the impact of PALSONIFY, atumelnant and our pipeline. I want to extend my deepest gratitude for the relentless dedication, brilliance and passion of our extraordinary employees, who have worked tirelessly to bring our scientific vision to life, as well as the clinical partners and patient communities who have championed our mission from the very beginning.”

Financial Benefits

The transaction is expected to contribute immediately to Vertex’s revenue growth via the ongoing launch of PALSONIFY, which has blockbuster potential in acromegaly. Longer term, atumelnant has the potential to be a multi-billion-dollar opportunity in CAH, with additional upside from its potential in Cushing’s syndrome. At peak, these assets have the potential to deliver more than $5 billion in combined annual revenue, which will further Vertex’s goal of delivering sustained double-digit revenue growth, in addition to industry leading operating margins. The transaction is expected to become accretive to non-GAAP operating income in 2029.

Transaction Terms and Financing

Under the terms of the merger agreement, Vertex will acquire all outstanding shares of Crinetics common stock for $85 per share in cash for a total equity value of approximately $10.0 billion or $8.8 billion net of estimated cash acquired. Vertex expects to finance the acquisition using a combination of cash on hand and debt, supported by $4.5 billion of fully committed bridge financing from Bank of America, N.A. and Morgan Stanley Senior Funding, Inc.

The transaction is expected to close in the third quarter of 2026, subject to customary closing conditions, including receipt of regulatory approvals and approval by Crinetics shareholders.
