Business Description

Overview Indivior Pharmaceuticals, Inc. and its subsidiaries (together, "Indivior" or the "Company") is the market leader in long-acting injectable medications for opioid use disorder (OUD). Indivior is focused on delivering evidence-based pharmacotherapies for OUD and is committed to advancing the neurobiological understanding of OUD as a chronic, relapsing, but treatable brain disease. For more than 25 years, Indivior has led innovation in addiction medicine, developing differentiated therapeutic solutions that support long-term patient recovery, expand access to care, and drive sustainable value for patients, healthcare systems and stockholders. Headquartered in the U.S. in Richmond, Virginia, Indivior and its portfolio of products is available primarily in the U.S. with additional products available in Canada, Australia, France, and Germany. Our core products include the following approved treatments: • SUBLOCADE (buprenorphine extended-release monthly injection); and • SUBOXONE Film (buprenorphine and naloxone sublingual film); both of which are treatments for OUD. Product availability varies across the countries in which Indivior treatments are available, including in terms of dosage, strength and indication. Our core geographic market (based on the country where the sale originates) is the U.S., which accounted for 85%, 85%, and 83% of net revenues for the years ended December 31, 2025, 2024, and 2023, respectively. In the U.S., we sell only SUBLOCADE and SUBOXONE Film. Corporate History Our business was initially developed and managed as a separate division of Reckitt Benckiser Group PLC (“RB” and, together with its subsidiaries, the “RB Group”), a public limited company incorporated under the laws of England and Wales. Indivior PLC was incorporated on September 26, 2014, for the purpose of acquiring the specialty pharmaceutical business unit from RB (the “Demerger”). Following the Demerger, which was effective on December 23, 2014, Indivior PLC operated as a standalone business. On December 11, 2025, our stockholders approved a plan to change our domicile to the U.S. On January 23, 2026, Indivior Pharmaceuticals, Inc., a corporation formed in Delaware on October 28, 2025 (“Indivior Pharmaceuticals”), became the ultimate parent company of Indivior PLC, a public company limited by shares incorporated under the laws of England and Wales (“Indivior PLC”), and its subsidiaries pursuant to a court-approved scheme of arrangement under Part 26 of the U.K. Companies Act 2006 (the “Scheme of Arrangement”) as part of Indivior PLC’s previously announced intention to change its corporate domicile to the United States (the “U.S. Domestication”). Pursuant to the Scheme of Arrangement, each ordinary share in the capital of Indivior PLC was cancelled. In consideration for this cancellation, each stockholder received one share of common stock, par value $0.001 per share, of Indivior Pharmaceuticals, Inc. for every ordinary share they previously held in Indivior PLC. After the delivery of the order of the High Court of Justice in England and Wales sanctioning the Scheme of Arrangement to the Registrar of Companies in England and Wales, and after the close of market trading on January 23, 2026, the Scheme of Arrangement became effective and binding on all stockholders of Indivior PLC and Indivior PLC became a wholly-owned subsidiary of Indivior Pharmaceuticals, Inc., thereby completing the U.S. Domestication. After this order, Indivior PLC became Indivior Limited. Previously, the ordinary shares of Indivior PLC were listed on the Nasdaq Global Select Market (“Nasdaq”) and registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) prior to the U.S. Domestication. The issuance of shares of common stock of Indivior Pharmaceuticals, Inc. pursuant to the Scheme of Arrangement was exempt from registration under Section 7 3(a)(10) of the Securities Act of 1933, as amended (the “Securities Act”). Further, pursuant to Rule 12g-3(a) under the Exchange Act, Indivior Pharmaceuticals, Inc. is the successor issuer to Indivior PLC and Indivior Pharmaceuticals, Inc.'s common stock is therefore deemed to be registered under Section 12(b) of the Exchange Act. Because the U.S. Domestication was completed after December 31, 2025, the financial statements included herein are those of Indivior PLC. The U.S.…
