1. Business Overview, Basis of Presentation, and Recently Issued Accounting Standards

Business Overview

Indivior Pharmaceuticals, Inc. and its subsidiaries (together, "Indivior" or the "Company") is the leader in long-acting injectable medications for opioid use disorder (OUD). The Company's core products include SUBLOCADE (buprenorphine extended-release monthly injection) and SUBOXONE Film (buprenorphine and naloxone sublingual film), both of which are treatments for OUD.

On August 1, 2026, Indivior Pharmaceuticals, Inc., a Delaware corporation (“Indivior”) and Artemis Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of Indivior (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Supernus Pharmaceuticals, Inc., a Delaware corporation (prior to the Effective Time (as defined below), “Supernus”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, the Company's Merger Sub, a wholly owned subsidiary, will merge with and into Supernus (the “Merger”), with Supernus continuing as the surviving company, and as a wholly-owned subsidiary of Indivior following the transaction. As a result of the Merger, Indivior will change its name to Supernus, Inc. (subsequent to the Effective Time, the “Combined Company”).

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”) and as a result of the Merger, each share of common stock of Supernus issued and outstanding immediately prior to the Effective Time will be converted into the right to receive 1.5401 shares of common stock of Indivior and cash in lieu of fractional shares. Additionally, at the Effective Time and as a result of the Merger, outstanding Supernus equity awards will be automatically converted into Indivior equity awards. RSUs and stock options will generally retain their existing vesting and other terms, while PSUs will be converted into time-based RSUs and the related performance conditions will cease to apply. The conversion of the equity awards will occur at the same exchange ratio as applies to Supernus common stock in the Merger; the exercise price of converted Supernus stock options will also be correspondingly adjusted.

In connection with a termination of the Merger Agreement in certain limited circumstances, Indivior could be required to pay a termination fee to Supernus in the amount of $174 million and Supernus could be required to pay a termination fee to Indivior of $101 million.

Upon completion of the Merger, Indivior stockholders are expected to own approximately 56.5% of the Combined Company on a fully diluted basis and Supernus stockholders will own approximately 43.5% of the Combined Company on a fully diluted basis.

Indivior declared a special cash dividend in an aggregate amount of $1,000 million, which will be payable to (i) holders of record of the issued and outstanding Indivior Common Stock as of the October 30, 2026 record date and (ii) holders of certain Indivior equity awards outstanding as of such date with respect to the Indivior Common Stock underlying such Indivior equity award, with such special dividend to be paid following the Effective Time (the "Special Dividend").

In connection with the Merger Agreement and the Special Dividend, Indivior entered into a commitment letter with Citibank, N.A. pursuant to which Citibank, N.A. has committed to provide, subject to the terms and conditions thereof, a senior secured term loan facility in an aggregate principal amount of $650 million. Proceeds from the senior secured term loan facility, together with cash on hand of the combined company, are expected to be used to fund the Special Dividend.

Pursuant to the terms of the Merger Agreement, as of the Effective Time of the Merger, (i) the board of directors of Combined Company will consist ofeight individuals, including four individuals who are nominees of the board of directors of Indivior immediately prior to the Effective Time of the merger andfour individuals who are nominees of the board of directors of Supernus immediately prior to the Effective Time of the Merger; (ii) Jack A. Khattar will serve as Chief Executive Officer and as a member of the Combined Company board; and (iii) Timothy C. Dec will serve as Chief Financial Officer.

The Company has concluded that Supernus Pharmaceuticals, Inc. (“Supernus”) will be the accounting acquirer in the merger under Accounting Standards Codification (“ASC”) 805, Business Combinations. Because Indivior will be the legal parent and issuer of the equity consideration while Supernus is the accounting acquirer, the transaction will be accounted for as a reverse acquisition under ASC 805-40.

On October 15, 2026, Indivior's stockholders approved the issuance of shares of common stock of Indivior (par value $0.001 per share) in connection with the proposed merger. Also on October 15, 2026, Supernus stockholders approved certain proposals related to the merger. The transaction is expected to close on or about November 2, 2026, subject to the satisfaction or waiver of other specified closing conditions.

Basis of Presentation

The accompanying unaudited interim Condensed Consolidated Financial Statements and related notes should be read in conjunction with the audited Consolidated Financial Statements of Indivior Pharmaceuticals, Inc. and its subsidiaries and related notes as contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. The unaudited interim financial statements include all adjustments (consisting only of normal recurring adjustments) and accruals necessary in the judgment of management for a fair statement of the results for the periods presented.

Certain prior‑period amounts have been reclassified to conform to the current‑period presentation. These reclassifications had no impact on previously reported net income, comprehensive income, or cash flows.

The accounting policies of the Company are consistent with those disclosed in"Item 1. Financial Statements - Note 2. Summary of Significant Accounting Policies"of the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

Columns and rows within tables may not add due to rounding. Percentages and per share data have been calculated using actual, non-rounded figures.

Use of Estimates

The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported. Significant estimates are used in determining items such as accruals for returns, incentives and rebates, certain accrued expenses, acquisitions, and ongoing litigation. Actual results may differ from those estimates.

Recently Adopted Accounting Standards

ASU 2024-04, Debt - Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments, was issued in November 2024 and clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as induced conversions or debt extinguishments. ASU 2024-04 is effective for annual and interim periods beginning after December 15, 2025. The Company adopted ASU 2024-04 effective January 1, 2026 and applied the guidance on a prospective basis. The adoption of ASU 2024-04 did not have a material impact on the Company's condensed consolidated financial statements.

ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets was issued in July 2025 and allows entities to elect a practical expedient that assumes that the current conditions as of the balance sheet date do not change for the remaining life of the asset. ASU No. 2025-05 is effective for annual and interim periods beginning after December 15, 2025. The Company adopted ASU 2025-05 effective January 1, 2026 and applied the guidance on a prospective basis. The adoption of ASU 2025‑05 did not have a material impact on the Company’s condensed consolidated financial statements.

ASU 2025‑07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share‑Based Noncash Consideration from a Customer in a Revenue Contract refines the scope of derivative accounting under Topic 815 by introducing a new scope exception for certain contracts or embedded features that are not exchange traded and have underlyings based on the operations or activities specific to one of the parties to the contract. In addition, the ASU clarifies that share‑based noncash consideration received from a customer in exchange for goods or services is initially accounted for under Topic 606, Revenue from Contracts with Customers, unless and until the entity’s right to receive or retain such consideration becomes unconditional. The Company early adopted ASU 2025‑07 effective January 1, 2026 and applied the guidance on a prospective basis. The adoption of ASU 2025‑07 did not have a material impact on the Company’s condensed consolidated financial statements.

Recently Issued Accounting Standards Not Yet Adopted

ASU 2024-03: Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)—Disaggregation of Income Statement Expenses (as clarified by ASU 2025-01) was issued in November 2024, requires disclosure of specified information about certain costs and expenses in the notes to the financial statements and is required to be applied by the Company for annual periods beginning after December 31, 2026 and interim periods beginning after December 15, 2027. As this accounting standard only impacts disclosures, it is not expected to have a material impact on the Company’s financial statements.

ASU No. 2025-06, Intangibles-Goodwill and Other-Internal Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software was issued in September 2025 and removes all references to software development project stages. Software capitalization will begin when management has authorized and committed to funding the software project and when it is probable that the project will be completed and the software will be used to perform the function intended. ASU 2025-06 is effective for interim and annual periods beginning after December 15, 2027. The guidance may be applied on a prospective basis, a modified transition approach or a retrospective transition approach and allows for early adoption. Adoption is not expected to have a material impact on the Company's financial statements.

2. Segment, Geographic and Other Revenue Information

The Company operates in a single operating and reportable segment for all periods presented and the Chief Executive Officer has been identified as the chief operating decision maker (the “CODM”). The CODM reviews the Company's financial information on a consolidated basis for purposes of allocating resources and evaluating performance. The CODM uses income from operations to measure the profitability of the segment. These amounts are reported on the Condensed Consolidated Statements of Operations. The measure of segment assets is reported on the Condensed Consolidated Balance Sheets as total consolidated assets.

Effective in the first quarter of 2026, the Company updated the presentation of segment operating expenses provided to the CODM. Amounts previously reported separately as Sales and Marketing and General and Administrative expenses are now presented on a combined basis as Selling, General and Administrative expenses. This change reflects how segment information is currently reviewed by the CODM. Prior‑period segment information has been recast to conform to the current‑period presentation.

The financial data provided to the CODM is as follows:

1 Discontinued sales and marketing support for OPVEE® during Q3 2025.

2 Marketing and promotional activities for PERSERIS were discontinued in 2024.

Significant segment expenses within net income include cost of sales, selling, general and administrative, and research and development at the consolidated level. Other segment items within net income include operating income, interest (income), interest expense, loss on debt extinguishment, and income tax expense. The Company's CODM is also regularly provided depreciation and amortization and stock-based compensation expense information, both of which are presented above and are recorded within cost of sales and selling, general and administrative expenses.

Revenue recognized from performance obligations satisfied in previous periods was $33 million and $97 million in the three and nine months ended September 30, 2026 and $15 million and $60 million during the three and nine months ended September 30, 2025, respectively.

3. Income Tax

Indivior is subject to taxation in several different jurisdictions. The Company's tax provision for each period presented was calculated using a forecasted annual tax rate, adjusted for discrete items occurring during the applicable period to arrive at an effective tax rate. The effective income tax rates for the relevant periods are calculated as follows:

On January 26, 2026, the Company completed a redomiciliation to the United States, which resulted in a change in the applicable statutory income tax rate from the U.K. rate of 25% to the U.S. federal statutory rate of 21%.

The Company's income tax rate for the three months ended September 30, 2026 of 25% differs from the U.S. federal statutory rate of 21%, primarily driven by foreign earnings taxed at different tax rates, U.K. global minimum top-up tax, state taxes, and disallowed expenses, partially offset by U.K. innovation deductions.

The company's income tax rate for the nine months ended September 30, 2026 of 24% differs from the U.S. federal statutory rate of 21% primarily driven by foreign earnings taxed at different tax rates, U.K. global minimum top-up tax, state taxes, disallowed expenses and a write-off of U.K. Net Operating Losses, partially offset by U.K. innovation deductions.

The Company's income tax rate for the three months ended September 30, 2025 differs from the U.K. statutory rate of 25%, primarily due to U.K. innovation deductions and a reduction in Pillar II top-up tax expense, offset by disallowed expenses.

The Company's income tax rate for the nine months ended September 30, 2025 differs from the U.K. statutory rate of 25%, primarily due to expense recognized for a U.K. HMRC settlement which became probable during the second quarter of 2025, a valuation allowance against corporate interest limitation carryforwards, share-based compensation shortfall tax expense and disallowed expenses, partially offset by U.K. innovation deductions and intragroup financing transactions. The HMRC settlement relates to aspects of prior years' intercompany financing arrangements and is not expected to impact future tax rates.

The Company is subject to income taxation in many jurisdictions. Unrecognized tax benefits reflect the differences between tax positions the Company has taken or expect to take on income tax returns and the amounts recognized in its financial statements. Resolution of the related tax positions with the relevant tax authorities may take many years to complete, and such timing is not entirely within the Company's control.

Changes in unrecognized tax benefits are summarized as follows for the nine months ended September 30, 2026.

During the nine months ended September 30, 2026 there were no material changes to the Company's unrecognized tax benefit when compared to the year ended December 31, 2025.

The total amount of unrecognized tax benefits relating to the Company’s tax positions is subject to change based on future events including, but not limited to, the settlement of ongoing tax audits and assessments and the expiration of applicable statutes of limitations.

The Company files income tax returns in the U.S., U.K., and in various foreign, state and local jurisdictions. The Company is subject to tax audits in the various jurisdictions until the respective statutes of limitations expire. The Company is no longer subject to U.K. examinations by tax authorities for fiscal years before 2020 and U.S. federal income tax examinations by tax authorities for fiscal years before 2022. U.K. and U.S. state and local audits covering 2018 - 2023 are ongoing.

4. Inventories

Inventories consist of the following:

Inventory expected to be sold more than one year from the balance sheet date is classified as noncurrent inventory and recorded in other noncurrent assets on the condensed consolidated balance sheets. At September 30, 2026 and December 31, 2025, the noncurrent portion of inventory was $3 million and $2 million, respectively, consisting primarily of raw materials and consumables.

5. Property, Plant and Equipment, Net

Property, plant and equipment, net consist of the following:

Capital expenditures of $1 million and $6 million were included in accounts payable and accrued expenses at September 30, 2026 and December 31, 2025, respectively.

6. Accounts Payable and Accrued Expenses

7. Accrued Litigation Settlement Expenses

Opioid litigation

The accrual of $56 million at September 30, 2026 reflects the present value of the agreed amount in a settlement between Indivior, the plaintiffs' executive committee and certain state attorneys general covering certain opioid litigation (including cases in the Opioid MDL) brought by municipalities and tribes, as well as a separate settlement with the State and subdivisions of Maryland. During the nine months ended September 30, 2026, payments totaling $26 million were made under the Opioid MDL settlement agreement related to obligations for 2025 and 2026.

Other

The final installment of $8 million related to an indemnity settlement with Reckitt Benckiser was paid in the nine months ended September 30, 2026. The Company has no remaining obligations related to this matter.

See Note 13. Commitments and Contingencies for additional information on legal matters.

8. Debt

Convertible Senior Notes Due 2031

On March 17, 2026, the Company completed an offering of $500 million aggregate principal amount of 0.625% Convertible Senior Notes due 2031 (the "Notes"), which included an option to purchase up to an additional $50 million aggregate principal amount of the Notes granted to the initial purchasers, which was exercised in full (the "Convertible Notes Offering"). The Notes were offered at par and will mature on March 15, 2031, unless earlier converted, redeemed, or repurchased. At issuance, net proceeds to the Company were approximately $486 million, after deducting initial purchasers' discounts, commissions, and estimated offering expenses of approximately $14 million.

The Notes are senior, unsecured obligations of the Company, ranking equally in right of payment with all existing and future senior, unsecured indebtedness. The Notes are structurally subordinated to all indebtedness and other liabilities of the Company's subsidiaries. The Notes bear interest at 0.625% per annum, payable semi-annually in arrears on March 15 and September 15 of each year, commencing September 15, 2026. Interest expense related to the Notes is included in interest expense in the consolidated statement of operations.

Holders may convert their Notes at their option prior to the close of business on December 15, 2030, only upon satisfaction of one or more of the following conditions: (1) during any calendar quarter commencing after June 30, 2026, if the last reported sale price of the Company's common stock exceeds 130% of the conversion price of $41.66 per share for at least 20 of the 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter; (2) during thefive business days immediately following any 10-consecutive trading day period in which the trading price per one thousand USD principal amount of Notes was less than 98% of the product of the last reported sale price of the Company's common stock and the applicable conversion rate; (3) upon the occurrence of certain corporate events or distributions on the Company's common stock; or (4) if the Company calls the Notes for redemption. On or after December 16, 2030, through the second scheduled trading day immediately preceding the maturity date, holders may convert their Notes at any time.

The initial conversion rate is 24.0033 shares of common stock per one thousand USD principal amount of Notes, equivalent to an initial conversion price of approximately $41.66 per share, a premium of approximately 35% to the last reported sale price of $30.86 per share on March 12, 2026. The conversion rate is subject to adjustment upon the occurrence of certain events as described in the indenture. If a fundamental change occurs or the Company exercises its optional redemption right, a higher make-whole conversion rate will apply, subject to a maximum conversion rate of 32.4044 shares per one thousand USD principal amount. The maximum number of shares of common stock issuable upon conversion of the Notes, including at the maximum make-whole conversion rate, is approximately 16,202,200 shares.

Upon conversion, the Company will satisfy its conversion obligation through combination settlement, consisting of cash equal to the lesser of (i) the aggregate principal amount of Notes being converted or (ii) the daily conversion value during the applicable 25‑trading‑day observation period based on the volume‑weighted average price (“VWAP”) of the Company’s common stock, plus shares of common stock for any excess conversion value above such cash amount. The Company may also elect to settle conversions entirely in cash.

On or after March 20, 2029 and on or before the 25 th scheduled trading day before the maturity date, the Company may redeem the Notes, in whole or in part, at a cash redemption price equal to the principal amount plus accrued and unpaid interest, provided that the Notes are freely tradable and the last reported sale price of the Company's common stock exceeds 130% of the conversion price for at least 20 of the 30 consecutive trading days ending on the trading day immediately before the redemption notice is sent. If a fundamental change occurs, holders may require the Company to repurchase their Notes at a cash repurchase price equal to 100% of the principal amount plus accrued and unpaid interest.

As of September 30, 2026, the carrying value of the Notes was $488 million, net of unamortized issuance costs of $12 million, and the effective interest rate of the Notes was 1.17%.

As a result of the Special Dividend declared on September 16, 2026, holders of the Convertible Notes became entitled to exercise a temporary conversion right under the terms of the Notes, which caused the outstanding principal amount of the Notes to be classified as current liabilities as of September 30, 2026. The temporary conversion right expires following the dividend record date, at which time all remaining Notes will revert to noncurrent in accordance with the original maturity schedule. Refer to Note 1. Business Overview, Basis of Presentation, and Recently Issued Accounting Standards for additional details related to the Special Dividend and pending merger.

Repayment of Prior Indebtedness

In March 2026, the Company used a portion of the proceeds from the Notes to repay in full the $333 million outstanding balance under its Note Purchase Agreement dated November 4, 2024, resulting in an $18 million loss on debt extinguishment recognized in the condensed consolidated statement of operations for the nine months ended September 30, 2026.

9. Financial Instruments and Fair Value Measurements

Financial instruments include cash and cash equivalents, accounts receivable, accounts payable, debt, and investments in securities. The carrying value of these financial instruments, excluding debt instruments and the Company’s investments in corporate debt and equity securities, approximates fair value because of the short-term nature of these instruments.

The following three levels of inputs are used to measure fair value:

Level 1 — Quoted prices in active markets for identical assets and liabilities.

Level 2 — Significant other observable inputs.

Level 3 — Significant unobservable inputs.

The fair value of debt securities at September 30, 2026 and December 31, 2025 was $27 million and $28 million, respectively. The fair value of debt securities held at amortized cost was calculated based on quoted market prices which would be classified as Level 1 in the fair value hierarchy above. At September 30, 2026, the Company's debt securities were held as part of an agreement to fund insurance coverage. These debt securities are classified as long-term investments on the condensed consolidated balance sheets as access to the investments is subject to contractual restrictions, regardless of the underlying investment maturity.

The estimated fair value of the Convertible Senior Notes due 2031 at September 30, 2026 was approximately $526 million. The fair value was determined based on the quoted price of the Notes in an inactive market on the last trading day of the reporting period and has been classified as Level 2 in the fair value hierarchy.

10. Earnings Per Share

The table below summarizes the basic and diluted earnings per share calculation for each period:

1 No potential shares were excluded from the diluted earnings per share computation because of their antidilutive impact in the three and nine months ended September 30, 2026 and three and nine months ended September 30, 2025, respectively.

The weighted average number of shares is adjusted for the number of shares granted to the extent market conditions have been met at the balance sheet date and determined using the treasury stock method.

The Notes are evaluated for dilution using the if‑converted method. For the three and nine months ended September 30, 2026, as the average market price of the Company's common stock did not exceed the conversion price of $41.66, no incremental shares were included in diluted weighted-average shares outstanding.

11. Stockholders' Equity

Share Repurchase Program

In February 2026, the Company's Board of Directors authorized a share repurchase program of up to $400 million of the Company’s common stock over a period of up to 18 months. Repurchases may be made from time to time in open market transactions, privately negotiated transactions, accelerated share repurchase arrangements or other transactions, subject to market conditions, applicable legal requirements and other relevant factors.

During the three months ended March 31, 2026, the Company repurchased 3,974,153 shares of its common stock at an average price of $31.45 per share for total consideration of $125 million.

On May 1, 2026, the Company entered into an accelerated share repurchase agreement (the "ASR Agreement") to repurchase $175 million of the Company’s common stock under the $400 million share repurchase program described above. Pursuant to the terms of the ASR Agreement, the Company made an up-front payment totaling $175 million and received an initial delivery of 3,717,473 shares. The initial share delivery represented approximately 80 percent of the total shares expected to be repurchased under the ASR Agreement. The final number of shares repurchased under the ASR Agreement was determined based on the volume-weighted average price of the Company’s common stock during the term of the ASR Agreement, subject to adjustments in accordance with the terms of the agreement. The Company received additional settlement deliveries of 281,207 shares on June 1, 2026 and 665,860 shares on June 2, 2026, and the ASR Agreement was settled on June 2, 2026. In total, the Company repurchased 4,664,540 shares under the ASR at an average price of approximately $37.52 per share. The shares repurchased under the ASR were retired and recorded as a reduction of stockholders’ equity.

As of September 30, 2026, $100 million remained available for future repurchases under the share repurchase program.

12. Stock-Based Payments

The Company's stock-based compensation plans and related accounting are described in Note 15 to the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

Indivior Long-Term Incentive Plan (LTIP)

A summary of the service-based restricted stock awards and performance-based stock awards activity under the LTIP for the nine months ended September 30, 2026 is presented below (values in thousands):

Conditional awards of 2 million shares were granted in the nine months ended September 30, 2026 and 5 million in the nine months ended September 30, 2025 under the Company’s Long-Term Incentive Plan, respectively.

The weighted average fair value per share of the service-based restricted stock awards granted was $33.68 for the nine months ended September 30, 2026, based on the fair market value at the date of grant. The total fair value of restricted stock awards issued was $13 million for the nine months ended September 30, 2026.

The weighted average fair value per share of the performance-based stock awards granted per award was $53.87 for the nine months ended September 30, 2026, calculated using the weighted average fair market value for each of the component goals at the date of grant. Performance-based stock awards granted in the nine months ended September 30, 2026 vest based on the Company's relative total shareholder return compared to a peer group within the S&P Pharmaceutical Select Index, with vesting between 0% and 200% of target. The total fair value of performance-based stock awards issued was $85 million for the nine months ended September 30, 2026.

Compensation cost for unvested service-based restricted stock awards and performance-based restricted awards not yet recognized at September 30, 2026 was $34 million and $24 million, respectively. This compensation cost will be recognized over the expected remaining weighted-average period of 2.11 years and 2.17 years for service-based restricted stock awards and performance-based stock awards, respectively.

13. Commitments and Contingencies

Legal Proceedings and Contingencies

The Company records accruals for loss contingencies associated with legal matters when it is probable a liability will be incurred and the amount of loss can be reasonably estimated. This note also discusses certain legal matters for which a loss is reasonably possible, including some for which the Company cannot reasonably estimate the amount or range of possible loss, including because the claims remain at an early stage, are not fully developed, or the information necessary to evaluate the claims is not yet available. Adverse outcomes to such litigation, if any, could have a material impact to the Company. Legal proceedings or threats of legal proceedings for which the Company believes the possibility of loss is remote are not discussed in this note.

Dental Allegations

The Company has been named as a defendant in numerous lawsuits alleging that SUBOXONE Film was defectively designed and caused dental injury, and that the Company failed to properly warn of the risks of such injuries. The plaintiffs generally seek compensatory damages, as well as punitive damages and attorneys’ fees and costs. Plaintiffs and potential plaintiffs related to these lawsuits generally can be grouped as follows:

As of October 23, 2026, approximately 1,925 cases naming approximately 22,098 plaintiffs have been consolidated in multi-district litigation in the Northern District of Ohio. See In Re Suboxone (Buprenorphine/Naloxone) Film Products Liability Litigation, MDL No. 3092 (N.D. Oh.) (the "Dental MDL").

Dental MDL Schedule A Plaintiffs: one complaint filed in the Dental MDL on June 14, 2024 attached a schedule of nearly 10,000 plaintiffs (the “Schedule A Plaintiffs”). The parties negotiated a tolling agreement for the Schedule A Plaintiffs that would permit plaintiffs’ counsel additional time to investigate issues such as whether any Indivior product was used before determining whether to file individual complaints to be coordinated with the Dental MDL. Plaintiffs have been dismissing Schedule A claimants pursuant to a mechanism provided by the court. As of October 23, 2026, the plaintiffs had reduced the number of Schedule A claimants to approximately 4,813.

State Court Plaintiffs: one complaint has been filed in New Jersey state court, and the parties have agreed to toll the claims of no less than 1,043 other individuals in Delaware, New Jersey, and Virginia. Complaints have not yet been filed on behalf of the tolled individuals.

These lawsuits and claims follow a June 2022 required revision to the Prescribing Information and Patient Medication Guide about dental problems reported in connection with buprenorphine medicines dissolved in the mouth to treat opioid use disorder, which was required by the FDA of all manufacturers of these products.

The MDL cases are in their preliminary stages. Any bellwether trials in the MDL would not occur until the end of the first quarter of 2028 at the earliest.

The Company has begun its evaluation of the claims, believes it has meritorious defenses, and intends to vigorously defend itself. Given the status and preliminary stage of litigation, no estimate of possible loss can be made at this time.

Proposed class actions based on similar allegations as in the Dental MDL, but also relating to SUBOXONE Tablets, were filed in Quebec and British Columbia against various subsidiaries of the Company, among other defendants, in April 2024. The Company has begun its evaluation of the claims, believes it has meritorious defenses, and intends to vigorously defend itself. Given the status and preliminary stage of the litigation, no estimate of possible loss can be made at this time.

Civil Opioid Litigation

The Company is named as a defendant in a number of civil lawsuits alleging that manufacturers, distributors, and retailers of opioids engaged in a longstanding practice to market opioids as safe and effective for the treatment of long-term chronic pain to increase the market for opioids and their own market shares for opioids, or alleging individual personal injury claims. Most of these cases were consolidated and are pending in a federal multi-district litigation in the U.S. District Court for the Northern District of Ohio. See In re National Prescription Opiate Litigation, MDL No. 2804 (N.D. Oh.) (the “Opioid MDL”).

As previously disclosed, the Company in January 2026 finalized settlement of all cases involving (i) cities, counties and other government subdivisions of 49 states, including, in some instances, school districts and hospitals, along with the District of Columbia (DC) and (ii) a number of territories; and in 2025 finalized a separate settlement with the tribal nations (collectively, the "Master Settlement Agreements").

The Company separately reached a settlement in principle with Maryland as discussed below, as Maryland and its subdivisions did not join the Master Settlement Agreements. The Master Settlement Agreements include these states, DC, and certain territories along with government subdivisions (upwards of 10,000 subdivisions) and tribal nations that filed suit or never filed suit, and the parties are in the process of filing appropriate materials in the Opioid MDL to release these claims per the settlement agreement. Additionally, the Master Settlement Agreements released certain cases with similar allegations pending outside the Opioid MDL. Those cases have been dismissed or are in the process of being dismissed per the Master Settlement Agreements.

Maryland did not opt into the national Opioid MDL settlement. Instead, the Company negotiated a separate settlement with the Maryland Office of the Attorney General and reached an agreement in principle in January 2026. On June 23, 2026, Maryland confirmed final approval of the negotiated settlement agreement. A separate litigation settlement provision of $1.9 m as of September 30, 2026 represents management's best estimate of the expected settlement with Maryland. On July 7, 2026, Maryland's political subdivisions received notice of the settlement. All listed political subdivisions have joined, and the last form was received on October 15, 2026. The settlement will be finalized by signature of both parties in the coming weeks.

Once the process of dismissing these settled cases per the Master Settlement Agreements is completed (and if the Maryland settlement agreement in principle is finalized), the Company should be a party to only the following cases in the Opioid MDL:

•5 cases filed by private individual plaintiffs who have asserted claims relating to neonatal abstinence syndrome ("NAS"). Since a requirement by the court in the MDL to file "fact sheets" related to their cases, over 100 plaintiffs have had their cases dismissed or have dismissed their cases against the Company.

•cases filed byone third party payor andone individual plaintiff. In each of these cases the Company is not the only defendant.

The Company expects that all lawsuits outside the Opioid MDL with allegations similar to the Opioid MDL will be dismissed with the exception of the West Virginia NAS matters, where the plaintiffs filed a notice of appeal in the West Virginia Supreme Court on February 27, 2025. Briefing on this matter was completed in August 2025. As of the date of this filing, there has been no decision by the West Virginia Supreme Court.

With respect to the cases still pending that it does not anticipate will be dismissed, the Company has begun its evaluation of all of the claims, believes it has meritorious defenses, and intends to vigorously defend itself. Given the status and preliminary stage of litigation in these cases, no estimate of possible loss for those matters can be made at this time.

U.K. Shareholder Claims

On September 21, 2022, certain shareholders issued representative and multiparty claims against Indivior PLC in the High Court of Justice for the Business and Property Courts of England and Wales, King’s Bench Division. The representative action was struck out and affirmed on appeal, so only the multiparty action remains. The claims made in the multiparty action generally allege that Indivior PLC (now known as Indivior Limited) violated the U.K. Financial Services and Markets Act 2000 (“FSMA 2000”) by making false or misleading statements or material omissions in public disclosures, including the 2014 Demerger Prospectus, regarding an alleged product-hopping scheme regarding the switch from SUBOXONE Tablets to SUBOXONE Film.

In the second half of 2025, those certain shareholders served their "Particulars of Claim" related to the multiparty action and the Company served its Defence. The parties have exchanged certain limited information related to the Particulars of Claim and the Defence since that time. The first case management conference occurred on July 23-24, 2026, at which the court directed a split trial. The first trial, covering certain matters going to liability (in particular, whether the Company's published information was misleading / contained material omissions, and whether the directors were aware of any such misstatements or omissions), will be scheduled for Q4 2028 for 8 weeks. A decision would not be expected in this trial until the first half of 2029. Following the first trial, if the Company is found liable, the parties would then work to schedule a second trial, which likely would not occur until late 2030 at the earliest. The Company has begun its evaluation of the claims, believes it has meritorious defenses, and intends to vigorously defend itself. Given the status and preliminary stage of the litigation, no estimate of possible loss can be made at this time.

False Claims Act Allegations

In August 2018, the U.S. District Court for the Western District of Virginia unsealed a declined qui tam complaint alleging causes of action under the federal and state False Claims Acts against certain entities within the Company predicated on best price issues and claims of retaliation. See United States ex rel. Miller v. Reckitt Benckiser Group PLC et al., Case No. 1:15-cv-00017 (W.D. Va.). The suit also seeks reasonable attorneys’ fees and costs. The Company filed a Motion to Dismiss in June 2021, which was granted in part and denied in part on October 17, 2023. The relator filed a sixth amended complaint against only Indivior Inc. on December 7, 2023, which Indivior answered on March 18, 2024. Discovery has been stayed pending resolution of certain discovery disputes.

The Company is evaluating the claims, believes it has meritorious defenses, and intends to vigorously defend itself. Given the status and preliminary stage of the litigation, no estimate of possible loss can be made at this time.

14. Restructuring

The following table summarizes restructuring activity related to major initiatives as part of Phase I of the Indivior Action Agenda — Generate Momentum for the nine months ended September 30, 2026:

Cumulative restructuring charges incurred since the inception of the program were $143 million as of September 30, 2026, of which $16 million was recognized during the nine months ended September 30, 2026. $8 million of restructuring charges were recognized within research and development expenses and consisted of the impairment of long-lived assets.

No significant additional costs related to this initiative are expected to be incurred.

During the three months ended June 30, 2026, the Company initiated a restructuring initiative primarily related to the decision to cease Phase 3 development of INDV-6001 and to not advance

INDV-2000 internally. The following table summarizes activity related to this initiative for the nine months ended September 30, 2026:

Cumulative restructuring charges incurred since the inception of the program were $6 million of severance, legal, consulting, and other corporate initiative transition costs, of which $5 million was recorded within research and development expenses and $1 million was recorded within selling, general and administrative expenses. No significant additional costs related to this initiative are expected to be incurred.

Outstanding liabilities related to restructuring activities are expected to be settled within the next twelve months.

15. Subsequent Events

Merger Agreement with Supernus

On October 15, 2026, at a special meeting of Indivior's stockholders, the stockholders approved the issuance of shares of common stock of Indivior (par value $0.001 per share) in connection with the proposed merger. Also on October 15, 2026, Supernus stockholders approved certain proposals related to the merger. These approvals were conditions to the consummation of the merger.

Divestiture

On October 19, 2026, the Company entered into an asset purchase agreement with a third party to divest its SUBUTEX tablet business in France and Germany for $95 million.90% of the purchase price will be paid at closing, with the balance to be paid upon regulatory approval of the transfer of the relevant marketing authorizations. The Company expects the transaction to close later in 2026, and for the relevant regulatory approvals to be obtained in the first half of 2027. This business contributed less than 4% of the Company’s total net revenues in 2025 with a smaller contribution expected in 2026. Additionally, at closing, the parties will enter into an agreement for the sale of remaining SUBUTEX inventory for the French and German markets upon transfer of the marketing authorizations.
