• Record Quarterly GAAP Net Income of $122 Million and Record Non-GAAP Net Income of $142 Million in Q2’26

• Record Quarterly Adjusted EBITDA of $186 Million in Q2’26, Up 111% YoY

Richmond, VA, August 3, 2026 – Indivior Pharmaceuticals, Inc. (Nasdaq: INDV) today reported its financial results for the second quarter ended June 30, 2026, and raised its full-year 2026 financial guidance.

“Exceptional operational execution in Phase II – Accelerate – of the Indivior Action Agenda fueled strong SUBLOCADE performance in the quarter and is the primary driver of our raised 2026 guidance,” said Joe Ciaffoni, Chief Executive Officer. “We remain focused on Phase II – Accelerate – for the remainder of 2026 and look forward to closing our proposed merger with Supernus, which is expected in the fourth quarter. Upon the close of our proposed merger, all three Phases of the Indivior Action Agenda will have been successfully completed.”

“We delivered record SUBLOCADE net revenue and adjusted EBITDA in the quarter leading us to raise our 2026 guidance,” said Ryan Preblick, Chief Financial Officer. “We now expect 2026 total SUBLOCADE net revenue growth of 20% year-over-year and adjusted EBITDA growth of 68% year-over-year at the midpoint of our guidance ranges. We returned capital to our shareholders through the repurchase of $175 million in shares during the quarter. We are committed to creating long-term shareholder value.”

Q2 2026 Business Highlights:

•

As of June 30, 2026, over 545,000 patients in the U.S. have been prescribed SUBLOCADE since launch.

•

Grew total SUBLOCADE net revenue 21% year-over-year to $253 million. U.S. SUBLOCADE net revenue increased 22% year-over-year to $238 million versus the prior year, driven by 18% dispense unit volume growth. New patient starts of 32,816 were a record. Net revenue also benefited from more favorable price/mix and gross-to-net adjustments.

•

In the second quarter, Indivior repurchased 4,664,540 shares at an average price of $37.52 for a total of $175 million. Year-to-date, the Company has repurchased 8,638,693 shares at an average price of $34.73 for a total of $300 million.

•

Announced findings from two new real-world evidence studies showing that adherence to SUBLOCADE is associated with lower relapse risk, fewer infection-related complications, and reduced healthcare utilization among people living with opioid use disorder (OUD).

•

Indivior Pharmaceuticals, Inc. and Supernus Pharmaceuticals, Inc. today announced a definitive agreement to combine in an all-stock merger of equals transaction to create a leading, diversified, scaled, CNS-focused biopharmaceutical company. For additional information on the transaction, please reference the announcement press release at Indivior.com.

Raising Full-Year 2026 Financial Guidance:

Full-year financial guidance assumes no material change in exchange rates for key currencies compared with 2025 average rates, notably USD/GBP and USD/EUR.


	Prior FY 2026 Guidance (4/30/2026)	Revised FY 2026 Guidance
Net Revenue	$1,215 million to $1,285 million	$1,295 million to $1,365 million
Total SUBLOCADE Net Revenue	$950 million to $990 million	$1,010 million to $1,050 million
Non-GAAP Operating Expenses*	$430 million to $450 million	$430 million to $450 million
Adjusted EBITDA*	$620 million to $660 million	$700 million to $740 million

We have not provided the forward-looking U.S. GAAP equivalents for certain forward-looking non-U.S. GAAP metrics as a result of the uncertainty and potential variability of reconciling items. Accordingly, the Company has relied upon the exception in Item 10(e)(1)(i)(B) of Regulation S-K to exclude such reconciliations, as the reconciliations of these non-U.S. GAAP guidance metrics to their corresponding U.S. GAAP equivalents are not available without unreasonable effort.

Non-GAAP Financial Measures:

Non-GAAP financial measures adjust for non-recurring items and other items representing expenses or income that we believe do not reflect the Company’s ongoing operations or the adjustment of which may help with the comparison to prior periods. The Company believes its non-GAAP financial measures may be useful to investors to understand the Company’s performance. In addition, the Company uses “Adjusted EBITDA” in its annual incentive plan in which all executive officers participate.

Adjusted EBITDA

Adjusted EBITDA is a non-GAAP financial measure that represents GAAP net income adjusted to exclude interest expense, interest income, income tax expense or benefit, depreciation and amortization, stock-based compensation, and other adjustments reflecting changes in our business that do not represent ongoing operations. Adjusted EBITDA, as used by us, may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.

Forward-looking statements include, among other things, express and implied statements regarding: potential deployment of capital to create long-term value for shareholders, including potential share repurchases and potential business development opportunities and acquisitions of next growth drivers; expected acceleration of SUBLOCADE U.S. dispense unit and net revenue growth throughout 2026; planned initiatives to accelerate SUBLOCADE growth; the Company’s financial guidance for 2026, including total net revenue, SUBLOCADE® net revenue, non-GAAP operating expenses, adjusted EBITDA, and cash flow from operations; planned initiatives to simplify the organization and accelerate Adjusted EBITDA and Cash Flow; anticipated benefits of the proposed merger with Supernus, the expected timing of completion of the proposed merger, estimated costs associated with the proposed merger; and other statements containing the words "believe," "anticipate," "plan," "expect," "intend," "estimate," "forecast," “strategy,” “target,” “guidance,” “outlook,” “potential,” "project," "priority," "may," "will," "should," "would," "could," "can," the negatives thereof, and variations thereon and similar expressions. Actual results may differ materially from those expressed or implied in these forward-looking statements due to a number of factors, including: our ability to identify accretive investment opportunities, to negotiate with third parties to acquire such assets, to obtain necessary regulatory approvals, and to efficiently manage such assets and execute upon opportunities; lower than expected future sales of our products; greater than expected impacts from competition; unanticipated costs including the effects of potential tariffs and potential retaliatory tariffs; whether we are able to identify efficiencies and fund additional investments that we expect to generate increased revenue, and the timing of such actions; market acceptance of long-acting injectables; cash available for share repurchases in the future, and the market price of our common stock in the future; the risk that the proposed merger with Supernus may not be completed on the anticipated timeline or at all; the failure to obtain required stockholder or regulatory approvals for the merger, or the imposition of conditions in connection with such approvals; the restrictions during the pendency of the transaction that may limit the parties' ability to pursue business opportunities or strategic transactions; the risk that the anticipated benefits, synergies, growth, profitability, cash flow generation and earnings accretion of the merger are not realized or are realized more slowly than expected; and the difficulties, costs and risks relating to the integration of the two businesses. For additional information about some of the risks and important factors that could affect our future results and financial condition, see "Risk Factors" in our Annual Report on Form 10-K filed February 26, 2026, and in our other filings with the U.S. Securities and Exchange Commission. Forward-looking statements speak only as of the date that they are made and should be regarded solely as our current plans, estimates and beliefs. Except as required by law, we do not undertake and specifically decline any obligation to update, republish or revise forward-looking statements to reflect future events or circumstances or to reflect the occurrence of unanticipated events.

SUBLOCADE® (buprenorphine extended-release) injection, for subcutaneous use (CIII) INDICATION SUBLOCADE is indicated for the treatment of moderate to severe opioid use disorder in patients who have initiated treatment with a single dose of a transmucosal buprenorphine product or who are already being treated with buprenorphine. SUBLOCADE should be used as part of a complete treatment plan that includes counseling and psychosocial support. HIGHLIGHTED SAFETY INFORMATION WARNING: RISK OF SERIOUS HARM OR DEATH WITH INTRAVENOUS ADMINISTRATION; SUBLOCADE RISK EVALUATION AND MITIGATION STRATEGY See full prescribing information for complete boxed warning. Serious harm or death could result if administered intravenously. SUBLOCADE is only available through a restricted program called the SUBLOCADE REMS Program. Healthcare settings and pharmacies that order and dispense SUBLOCADE must be certified in this program and comply with the REMS requirements. CONTRAINDICATIONS Hypersensitivity to buprenorphine or any other ingredients in SUBLOCADE. WARNINGS AND PRECAUTIONS Addiction, Abuse, and Misuse: SUBLOCADE contains buprenorphine, a Schedule III controlled substance that can be abused in a manner similar to other opioids. Monitor patients for conditions indicative of diversion or progression of opioid dependence and addictive behaviors. Respiratory Depression: Life threatening respiratory depression and death have occurred in association with buprenorphine. Warn patients of the potential danger of self-administration of benzodiazepines or other CNS depressants while under treatment with SUBLOCADE. Risk of Serious Injection Site Reactions: Likelihood of serious injection site reactions may increase with inadvertent intramuscular or intradermal administration. Evaluate and treat as appropriate. The most common injection site reactions are pain, erythema and pruritus with some involving abscess, ulceration and necrosis. Neonatal Opioid Withdrawal Syndrome: Neonatal opioid withdrawal syndrome (NOWS) is an expected and treatable outcome of prolonged use of opioids during pregnancy. Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off the opioid. Risk of Opioid Withdrawal With Abrupt Discontinuation: If treatment with SUBLOCADE is discontinued, monitor patients for several months for withdrawal and treat appropriately. Risk of Hepatitis, Hepatic Events: Monitor liver function tests prior to and during treatment. Risk of Withdrawal in Patients Dependent on Full Agonist Opioids: Verify that patients have tolerated transmucosal buprenorphine before injecting SUBLOCADE. Treatment of Emergent Acute Pain: Treat pain with a non-opioid analgesic whenever possible. If opioid therapy is required, monitor patients closely because higher doses may be required for analgesic effect. ADVERSE REACTIONS Adverse reactions commonly associated with SUBLOCADE (in ≥5% of subjects) were constipation, headache, nausea, injection site pruritus, vomiting, increased hepatic enzymes, fatigue, and injection site pain.
