I N V E S T O R P R E S E N T A T I O N \| J U N E 2 0 2 5 Important Cautionary Statement Regarding Forward-looking Statements This presentation contains certain statements that are forward-looking. Forward-looking statements include, among other things, express and implied statements regarding expected future cash flows; the Company's financial guidance including operating and profit margins for 2025 and its medium- and long-term growth outlook; expected future savings; expected future growth and expectations for sales levels for particular products; expected future product launches in particular markets; expected growth in LAI usage, the prescriber base, payor access, and the number of patients treated with our products; our product development pipeline and potential future products, the timing of clinical trials, expectations regarding regulatory approval of such product candidates, the timing of such approvals, and the timing of commercial launch of such products or product candidates, and eventual annual revenues of such future products; patent applications the potential future issuance of patents; 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, guidance, the negatives thereof, and variations thereon and similar expressions. By their nature, forward-looking statements involve risks and uncertainties as they relate to events or circumstances that may or may not occur in the future. c Actual results may differ materially from those expressed or implied in these forward-looking statements due to a number of factors, including: lower than expected future sales of our products; greater than expected impacts from competition; failure to achieve market acceptance of OPVEE; 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 revenues, and the timing of such actions; and other unanticipated events. For additional information about some of the risks and important factors that could affect our future results and financial condition, see Risk Factors in Indivior's Annual Report on Form 10-K for the fiscal year 2024 filed March 3, 2025 and its other filings with the U.S. Securities and Exchange Commission.

I N V E S T O R P R E S E N T A T I O N \| J U N E 2 0 2 5 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 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.

I N V E S T O R P R E S E N T A T I O N \| J U N E 2 0 2 5 OPVEE® (nalmefene) nasal spray INDICATION AND USAGE OPVEE nasal spray is an opioid antagonist indicated for the emergency treatment of known or suspected overdose induced by natural or synthetic opioids in adults and pediatric patients aged 12 years and older, as manifested by respiratory and/or central nervous system depression. OPVEE nasal spray is intended for immediate administration as emergency therapy in settings where opioids may be present. OPVEE nasal spray is not a substitute for emergency medical care. HIGHLIGHTED SAFETY INFORMATION CONTRAINDICATIONS Hypersensitivity to nalmefene or to any of the other ingredients. WARNINGS AND PRECAUTIONS Risk of Recurrent Respiratory and Central Nervous System Depression: While the duration of action of nalmefene is as long as most opioids, a recurrence of respiratory depression is possible, therefore, keep patient under continued surveillance and administer repeat doses of OPVEE using a new nasal spray with each dose, as necessary, while awaiting emergency medical assistance. Limited Efficacy with Partial Agonists or Mixed Agonist/Antagonists: Reversal of respiratory depression caused by partial agonists or mixed agonists/antagonists, such as buprenorphine and pentazocine, may be incomplete. Larger or repeat doses may be required. Precipitation of Severe Opioid Withdrawal: Use in patients who are opioid dependent may precipitate opioid withdrawal. In neonates, opioid withdrawal may be life-threatening if not recognized and properly treated. Monitor for the development of opioid withdrawal. Risk of Cardiovascular (CV) Effects: Abrupt postoperative reversal of opioid depression may result in adverse CV effects. These events have primarily occurred in patients who had preexisting CV disorders or received other drugs that may have similar adverse CV effects. Monitor these patients closely in an appropriate healthcare setting after use of nalmefene hydrochloride. Risk of Opioid Overdose from Attempts to Overcome the Blockade: Attempts to overcome opioid withdrawal symptoms caused by opioid antagonists with high or repeated doses of exogenous opioids may lead to opioid intoxication and death. ADVERSE REACTIONS Most common adverse reactions (incidence at least 2%) are nasal discomfort, headache, nausea, dizziness, hot flush, vomiting, anxiety, fatigue, nasal congestion, throat irritation, rhinalgia, decreased appetite, dysgeusia, erythema, and hyperhidrosis.
