Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
(d) Appointment of Stuart A. (Tony) Kingsley to the Board of Directors
On June 24, 2025, the Board of Directors of Indivior PLC (the “Company” or “Indivior”) announced that it appointed Stuart A. (Tony) Kingsley as a non-executive director effective July 1, 2025. The Company expects to appoint Mr. Kingsley to board committees at a later date.
Mr. Kingsley was selected by the Company to become a member of the Board of Directors with the assistance of a national search firm. Mr. Kingsley's appointment is consistent with Section 3.1.3 of the Amended and Restated Relationship Agreement between the Company and Oaktree Value Opportunities Fund, L.P., Oaktree London Liquid Value Opportunities Fund (VOF), L.P., Oaktree Phoenix Investment Fund, L.P. and Boston Patriot Arlington ST LLC made March 3, 2025, and there are no arrangements or understandings between Mr. Kingsley and any other person pursuant to which he was selected as a director.
The Company will compensate Mr. Kingsley for his service as a director consistent with all other non-executive directors and as set forth in the 2025 Directors’ Remuneration Policy, the complete text of which is set forth in Appendix 1 to the Company’s Notice of Annual General Meeting dated March 27, 2025 for the meeting held on May 8, 2025, a copy of which is available in the Investor Relations section of the Company’s website, www.indivior.com.
Mr. Kingsley has no direct or indirect material interest in any transaction in which the Company is or is to be a participant and which would require reporting under Item 404(a) of Regulation S-K. There are no family relationships between Mr. Kingsley and any Company director or executive officer.
The Company’s related press release is attached as Exhibit 99.1 to this Current Report on Form 8−K and is incorporated by reference in its entirety.
Item 8.01 Other.
Director Equity Arrangements
As contemplated by the Company’s Remuneration Policy approved by shareholders on May 8, 2025, the Company took the following steps to facilitate an increase in the share ownership by its non-executive directors.
Specifically, effective June 20, 2025, each of Keith Humphreys, Daniel Ninivaggi, Barbara Ryan, Mark Stejbach, and David Wheadon (collectively, the “NEDs”), being the U.S. based non-executive directors of the Board of Directors, entered into a Purchase Plan with J.P Morgan Securities LLC (“JPMS”), pursuant to which JPMS will make quarterly purchases of the Company’s securities on behalf of each NED (the "Purchase Plan"). The NEDs intend for the Purchase Plan to qualify under SEC Rule 10b5-1. Pursuant to Paragraph 4 of the Purchase Plan, each NED authorizes the Company to make payment to JPMS of the purchase price on their behalf. Shares purchased on behalf of the NEDs will be subject to a one-year holding period.
Indivior PLC entered into a letter agreement with the NEDs on June 20, 2025 pursuant which Indivior will pay JPMS for all stock purchases made under the plan on behalf of the NEDs and represented to the NEDs that the Company was not aware of any material non-public information at the time they entered into the Purchase Plan.
Together, the two agreements allow each NED effectively to defer approximately 70% of their after-tax, base retainer fee for service as a director into Company shares (80% in the case of Dr. Wheadon).
Separately, Juliet Thompson, who is a U.K.-based non-executive director of the Company, and Timothy Thompson, who is a person closely associated with Juliet Thompson, purchased 1,925 and 3,850 Ordinary Shares, respectively, on June 11, 2025. Following this transaction, Ms. Thompson has an interest in 9,625 Ordinary Shares of the Company. The Company will reimburse Ms. Thompson for these purchases pursuant to the 2025 Directors' Remuneration Policy over the course of the next year.

Purchase Plan

Purchase Plan, adopted June 18, 2025 (the “Purchase Plan”, and such date, the “Adoption Date”), among: (a) Keith Humphreys; (b) Daniel Ninivaggi; (c) Barbara Ryan; (d) Mark Stejbach and (e) David Wheadon; (each of (a), (b), (c), (d) and (e), a “Purchaser”, and collectively “Purchasers”); and (f) J.P. Morgan Securities LLC (“JPMS”).

RECITALS

WHEREAS, the Purchasers desire to establish this Purchase Plan to buy ordinary shares, $0.50 nominal value per share (the “Stock”) of Indivior PLC (the “Issuer”).

WHEREAS, the Purchasers desire to buy a total number of shares of Stock with an aggregate purchase price (before deduction of standard and customary commissions and fees) of between $680,000 (the “Minimum Total Buying Limit”) and $715,000 (the “Maximum Total Buying Limit”) from the Purchase Commencement Date to the Purchase Plan End Date (all shares of Stock purchased pursuant to this Purchase Plan, the “Total Plan Shares”);

WHEREAS, the Purchasers desire to engage JPMS to effect purchases of shares of Stock in accordance with the Purchase Plan;

NOW, THEREFORE, the Purchasers and JPMS hereby agree as follows:

A. IMPLEMENTATION OF THE PURCHASE PLAN

1.    JPMS shall effect purchases (each a “Purchase”) of shares of Stock only on days on which the NasdaqGS (the “Exchange”) is open and the Stock trades regular way on the Exchange (“Trading Day”), pursuant to the specific instructions specified on Schedule A.

2.    Each Purchaser acknowledges and agree that JPMS will handle the above order on a best efforts basis. In the event any limit prices of orders are away from the prevailing market at any time, there can be no assurance that such orders will be executed in whole or in part. Each Purchaser agrees that all orders may be partially executed and will not be treated as an all or none order.

1




3.    In accordance with JPMS’s customary procedures, JPMS will deposit shares of Stock purchased hereunder into the JPMorgan Chase Bank, N.A. Asset Custody Account or JPMS Margin Brokerage Account (“Account”) of each Purchaser against payment to JPMS (which, for the avoidance of doubt, may be made by such Purchaser or by Issuer on such Purchaser’s behalf pursuant to Paragraph A.4). Purchasers will be notified of all transactions pursuant to customary trade confirmations. Each Purchaser’s obligation to make payment in respect of any shares of Stock purchased for the Purchaser prior to any termination hereof shall survive such termination hereof.

4.    JPMS will charge its reasonable and customary commissions for the purchase of shares of Stock under this Purchase Plan, together with any other expenses incurred by JPMS in connection with such purchases. For the avoidance of doubt, each Purchaser authorizes the Issuer to make payment to JPMS of the purchase price on their behalf.

5.    The Total Plan Shares, other share amounts and prices, if applicable, set forth above and in Schedule A shall be adjusted automatically on a proportionate basis to take into account any stock split, reverse stock split or stock dividend with respect to the Stock or any change in capitalization with respect to the Issuer that occurs during the term of this Purchase Plan.

6.    Subject to Paragraph E.6, purchases will commence under this Purchase Plan on the Purchase Commencement Date, as defined in Schedule A, and shall terminate on the earlier of (a) the close of business on the Purchase Plan End Date, as defined in Schedule A; (b) the date on which the Total Plan Shares have been purchased; (c) the date this Purchase Plan is terminated pursuant to Section D; (d) if applicable, the dissolution or termination of any Purchasers’ existence under applicable law, provided that any such dissolution or termination shall be made in good faith and not (i) for the purpose of indirectly causing termination of this Purchase Plan, (ii) as a part of a plan or scheme to evade the prohibitions of Rule 10b5-1 or other applicable securities laws, or (iii) as a part of a plan or scheme to evade the provisions of Section E of this Purchase Plan; (e) the date on which the unit of JPMS responsible for executing purchases of Stock pursuant to this Purchase Plan receives notice or otherwise becomes aware of (i) the closing of a tender or exchange offer with respect to the Stock or of a merger, acquisition, reorganization, recapitalization or comparable transaction affecting the securities of the Issuer as a result of which the Stock is to be exchanged or converted into shares of another company or for other consideration; or (ii) the commencement or impending commencement of any proceedings in respect of or triggered by Purchasers’ bankruptcy or insolvency; or (f) the failure of the Purchasers to comply with Paragraph A.3 above. Notwithstanding the above, this Purchase Plan shall not be considered effective, but instead shall be considered null and void, if at least one of the accounts referenced in A.3 above has not been established in the name of each of the Purchasers and open for the receipt of Stock by the Purchase Commencement Date. Each Purchaser understands that such an account cannot be opened until JPMS, and its affiliates have performed customer due diligence and customer identification in accordance with internal policies and


2






procedures and relevant federal laws including, but not limited to, the Bank Secrecy Act as amended by the USA PATRIOT Act and the regulations promulgated thereunder.  Each Purchaser understands that there may be significant time delays during this process and that an account may not be open for the receipt of Stock by the Purchase Commencement Date.

7.    Each Purchaser acknowledges and agrees that it does not have authority, influence, or control over any purchases of Stock effected by JPMS pursuant to this Purchase Plan, and will not attempt to exercise any authority, influence or control over such purchases. JPMS agrees not to seek advice from Purchasers with respect to the manner in which it effects purchases under this Purchase Plan. JPMS may use its discretion in how to work the order to attempt to achieve the best execution below the maximum price per share, but at no time will the Purchasers communicate to JPMS any instructions on how to execute the order.

8.    Purchasers will be notified of all transactions pursuant to customary trade confirmations that are provided in the normal course of business. In addition, JPMS will use reasonable efforts to notify both the Issuer and the Purchasers via email of each transaction pursuant to this Purchase Plan no later than one Trading Day after the trading date of such transaction. Such notifications shall be sent to the following distribution list as indicated in Schedule A, or such other persons as the Issuer may direct in writing from time to time.

9.    Each Purchaser understands that JPMS may not be able to effect a purchase due to a market disruption or a legal, regulatory or contractual restriction or internal policy applicable to JPMS. If any purchase cannot be executed as required by Paragraph A.1, due to a market disruption, a legal, regulatory or contractual restriction applicable to JPMS or any other such event, such purchase shall be cancelled and shall not be effected pursuant to this Purchase Plan, and, notwithstanding any language to the contrary herein, there shall be no carryover associated with such cancelled purchase.

10.    It is the intent of the parties that this Purchase Plan comply with the requirements of Rule 10b5-1(c)(1)(i)(B) and Rule 10b-18 under the Securities Exchange Act of 1934 (the “Exchange Act”) and this Purchase Plan shall be interpreted to comply with the requirements thereof. JPMS shall comply with the requirements of paragraphs (b)(2), (b)(3) and (b)(4) of Rule 10b-18 under the Exchange Act in connection with Purchases of Stock in the open market pursuant to this Purchase Plan. Each Purchaser agrees not to take any action or cause another person to take any action that would cause Purchases not to comply with Rule 10b-18 or Rule 10b5-1.

B. REPRESENTATIONS AND AGREEMENTS OF PURCHASERS

1.    Each Purchaser (on behalf of itself and all persons holding any interest in or authority over such Purchaser, including without limitation trustees, beneficiaries,


3






grantors and their successors; such persons collectively, “Purchaser Related Persons”) represents and warrants that as of the time of execution of, and entering into, this Purchase Plan, (a) to the best of such Purchaser’s knowledge there is no blackout period (as defined in 17 C.F.R. Section 245.100(b), a “Blackout Period”) in effect for the Issuer, (b) neither such Purchaser nor any Purchaser Related Person is aware of any material, nonpublic information with respect to the Issuer or any securities of the Issuer (including the Stock) or of the actual or approximate beginning or ending dates of a Blackout Period for Issuer, and (c) such Purchaser is entering into this Purchase Plan, and the transactions contemplated herein, in good faith and not as part of a plan or scheme to evade the prohibitions of any applicable laws or regulations, such as Rules 10b5-1 and 10b-18 under the Exchange Act. Each Purchaser further agrees to act in good faith with regard to this Purchase Plan, including without limitation any suspension, termination and/or amendment. For the avoidance of doubt, to the extent a Purchaser is a director or officer of the Issuer (as defined in Rule 16a-1(f) under the Exchange Act, and regardless of whether Issuer is otherwise subject to Section 16 of the Exchange Act and the rules thereunder), such Purchaser’s representations in clauses (b) and (c) of this Paragraph B.1 are intended as “certifying” representations for purposes of Rule 10b5-1(c)(1)(ii)(C) under the Exchange Act.

2.    At the time of each Purchaser’s execution of this Purchase Plan, neither such Purchaser nor any Purchaser Related Person has: (a) entered into or altered a corresponding or hedging transaction with respect to the Total Plan Shares; or (b) entered into or given any additional contract, instruction, or plan that would qualify for the affirmative defense under Rule 10b5-1(c)(1) under the Exchange Act. While this Purchase Plan remains in effect, each Purchaser agrees: (c) not to enter into any such transaction described in clause (a); and (d) not to enter into or give any additional contract, instruction or plan described in clause (b) without the prior consent of JPMS. JPMS will require certain representations from an applicable Purchaser and acknowledgement of Issuer as a condition to granting such consent.

3.    Each Purchaser agrees to make all filings, if any, required under and monitor such Purchaser’s own compliance with Sections 13(d), 13(g) and 16 of the Exchange Act.

4.    Each Purchaser acknowledges and agrees that JPMS has no duty to determine whether Purchasers have violated Sections 13(d), 13(g) or 16 of the Securities Exchange Act of 1934, as amended, or the rules adopted by the SEC thereunder, or any other laws or regulations applicable to the Purchasers in connection with this Purchase Plan. Each Purchaser understands that this Plan in no way alters such Purchaser’s obligations and responsibilities under Section 16, including those prohibitions against short swing profits. JPMS has no duty to ascertain or advise on any reporting or disclosure requirements that may apply to the Issuer (including, without limitation, the obligations contained in the U.S. Securities and Exchange Commission’s December 2022 rulemaking regarding Rule 10b5-1 under the Exchange Act and related matters (publicly available at 87 Federal Register 80362 (Dec. 29, 2022)).


4







5.    Each Purchaser understands the laws and regulations of U.S. states or non-United States jurisdictions (collectively, “State or Foreign Regulation”) may impose further restrictions or limitations on purchases of shares of Stock by or on behalf of such Purchaser. State or Foreign Regulation may include, without limitation, the European Union Market Abuse Regulation (Regulation (EU) No 596/2014 of the European Parliament and of the Council of 16 April 2014). Each Purchaser acknowledges and agrees that JPMS has no duty to determine whether any State or Foreign Regulation would impose restrictions or limitations on this Purchase Plan. Each Purchaser understands that this Purchase Plan in no way alters such Purchaser’s obligations and responsibilities, or the obligations and responsibilities of the Issuer, under State or Foreign Regulation. For the avoidance of doubt, references in this Purchase Plan to applicable laws, regulations and legal/regulatory restrictions shall be construed to include any applicable State and Foreign Regulation.

6.    Each Purchaser acknowledges and agrees that JPMS has not provided such Purchaser with any tax, accounting or legal advice. Each Purchaser understands that such Purchaser should seek the advice of counsel regarding this Purchase Plan and the various securities and tax law issues related thereto.

7.    Each Purchaser agrees to notify JPMS immediately in the event of (a) trading restrictions being imposed as the result of any applicable regulatory prohibition or lock up event restricting purchases by or on behalf of affiliates, such as a stock offering or tender offer; (b) circumstances that would cause the purchases contemplated by this Purchase Plan not to qualify as “Rule 10b-18 purchases” as defined in Rule 10b-18(a)(13); or (c) “Rule 10b-18 purchases” of the Stock by the Purchasers other than those contemplated by this Purchase Plan.

8.    Each Purchaser represents and warrants that (a) such Purchaser is able to purchase shares of Stock, as contemplated by this Purchase Plan, in accordance with the Issuer’s insider trading policies, and (b) such Purchaser has, without contravening the representations and warranties in Paragraph B.2, obtained the acknowledgement of the Issuer to enter into this Purchase Plan.

9.    To the extent this Purchase Plan constitutes a contract, instruction or plan described in Rule 10b5-1(c)(1)(ii)(E) (a “Single-Trade Plan”), each Purchaser represents and warrants that it has not entered into, and will not enter into, another Single-Trade Plan within 12 months before or after the Adoption Date of this Purchase Plan.


C. INDEMNIFICATION AND LIMITATION ON LIABILITY

1.    Each Purchaser agrees, severally and not jointly, to indemnify and hold harmless JPMS and its directors, officers, employees and affiliates from and against all


5






claims, losses, damages and liabilities (including without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) arising out of or attributable to JPMS’s actions taken or not taken in compliance with this Purchase Plan or arising out of or attributable to any breach by such Purchaser of this Purchase Plan (including such Purchaser’s representations and warranties hereunder) or any violation by such Purchaser of applicable laws or regulations. This indemnification shall survive termination of this Purchase Plan. Notwithstanding the foregoing, the Purchasers shall have no indemnification obligation to the extent any claims, losses, damages or liabilities are due to the gross negligence, recklessness or willful misconduct of JPMS or any other person indemnified pursuant to this Paragraph C.1.a.

2.    Notwithstanding any other provision hereof, JPMS shall not be liable to any Purchaser for: (a) special, indirect, punitive, exemplary or consequential damages, or incidental losses or damages of any kind, even if advised of the possibility of such losses or damages or if such losses or damages could have been reasonably foreseen; or (b) any failure to perform or to cease performance or any delay in performance that results from a cause or circumstance that is beyond its reasonable control, including but not limited to failure of electronic or mechanical equipment, strikes, failure of common carrier or utility systems, severe weather, market disruptions or other causes commonly known as “acts of God”.

D. SUSPENSION, TERMINATION AND AMENDMENT

1.    This Purchase Plan may be (a) suspended or terminated by Issuer at any time upon one Trading Day prior written notice or (b) terminated by the Purchasers collectively at any time upon one Trading Day prior written notice; provided however that JPMS may in its sole discretion decide to suspend or terminate on the same Trading Day that written notice is provided, if JPMS deems such action practicable. Any such suspension or termination shall be made in good faith and not as a part of a plan or scheme to evade the prohibitions of Rule 10b5-1 or other applicable securities laws. JPMS will require certain representations from each Purchaser and acknowledgement of Issuer as a condition to such suspension or termination.

2.This Purchase Plan shall be suspended, or at JPMS’s option, terminated, with respect to the Purchasers collectively, if JPMS receives notice, whether pursuant to Paragraph B.7 or otherwise, of (a) the occurrence of any legal, contractual or regulatory restriction applicable to Purchasers or their affiliates, including without limitation, any restriction related to a merger or acquisition, or (b) a stock offering requiring an affiliate lock-up, that would prohibit purchases pursuant to this Purchase Plan, or (c) if the Stock has been delisted from the Exchange, or becomes subject to the delisting procedure from the Exchange.

3.    The Purchasers collectively may amend or modify the economic trading parameters of this Purchase Plan (such as the number, size, price and timing of orders, or


6






the percentage allocation of purchased shares among Purchasers) only upon the written consent of JPMS. Any such amendment or modification shall be made in good faith and not as a part of a plan or scheme to evade the prohibitions of Rule 10b5-1 or other applicable securities laws. Each Purchaser agrees that they will not amend or modify this Purchase Plan at any time: (a) that a Blackout Period is in effect for the Issuer or (b) that any Purchaser or any person controlling any Purchaser (as such term is defined in Rule 405 under the Securities Act), or any Purchaser Related Person, is aware of any material non-public information about the Issuer and/or the Stock or of the actual or approximate beginning or ending dates of a Blackout Period for Issuer. JPMS will require certain representations from Purchasers and acknowledgement of Issuer as a condition to such amendment or modification.

E. GENERAL

1.    This Purchase Plan shall be governed by and construed in accordance with the laws of the State of New York without reference to choice of law principles.
