This Cooperation Agreement (this “Agreement”), dated as of August 28, 2023 (the “Effective Date”), is by and among Elliott Investment Management L.P., a Delaware limited partnership, Elliott Associates, L.P., a Delaware limited partnership, and Elliott International, L.P., a Cayman Islands limited partnership (each, an “Elliott Party,” and, together, the “Elliott Parties”), and Catalent, Inc., a Delaware corporation (the “Company”). Capitalized terms in this Agreement shall have the meanings set forth in this Agreement.

WHEREAS, the Company and the Elliott Parties have engaged in discussions concerning the Company; and

WHEREAS, the Company and the Elliott Parties desire to enter into an agreement regarding the appointment of certain new, independent directors to the Board of Directors of the Company (the “Board”) and certain other matters, in each case, on the terms and subject to the conditions set forth herein.

NOW, THEREFORE, in consideration of and reliance upon the mutual covenants and agreements contained herein, the receipt and sufficiency of which are hereby acknowledged, the Elliott Parties and the Company agree as follows:

Section 1. Board of Directors.

(a) New Directors. As promptly as practicable following the Effective Date, the Board and all applicable committees thereof shall take (or shall have taken) such actions as are necessary to increase the size of the Board by four (4) and appoint Steven Barg (subject to the last sentence of Section 1(d)(i), the “Investor Designee”), Frank D’Amelio, Stephanie Okey, and Michelle R. Ryan (the “New Independent Directors,” and together with the Investor Designee, the “New Directors”) as members of the Board to fill the vacancies created by such increase in the Board, with an initial term expiring at the Company’s 2023 Annual Meeting of Stockholders (the “2023 Annual Meeting”).

(b) New Director Agreements, Arrangements, and Understandings. Each of the Elliott Parties represents, warrants, and agrees that neither it nor any of its Affiliates (i) has paid or will pay any compensation to any of the New Directors (including replacement candidates contemplated by Section 1(d)) for such individual’s service on the Board or any committee thereof following their appointment to the Board or (ii) has or will have any agreement, arrangement or understanding, written, or oral, with any of the New Directors (including replacement candidates contemplated by Section 1(d)) for such individual’s service on the Board or any committee thereof following their appointment to the Board.

(c) 2023 Annual Meeting Nominees. The Company and all applicable committees thereof shall take such actions as are necessary so that the slate of nominees standing and recommended by the Board for election at the 2023 Annual Meeting in the Company’s proxy statement and on its proxy card relating to the 2023 Annual Meeting shall include the four (4) New Directors and eight (8) other nominees selected by the Board to stand for election at the 2023 Annual Meeting.

(d) Replacement New Directors.

(i) If the Investor Designee is unable or unwilling to serve as a director, resigns as a director, is removed as a director, or ceases to be a director for any other reason prior to the expiration of the Cooperation Period, the Company and the Elliott Parties shall cooperate in good faith to identify and mutually agree, subject to Sections 1(e) and 1(f), upon a substitute Qualified Director (the “Replacement Investor Designee”), and the Board shall take such actions as are necessary to appoint the Replacement Investor Designee to serve as a director of the Company for the remainder of such Investor Designee’s term; provided that if the Elliott Parties identify and propose an employee of an Elliott Party or an Affiliate of an Elliott Party to serve as the Replacement Investor Designee, the Company’s agreement to such individual’s appointment shall not be unreasonably withheld, delayed or conditioned. Effective upon the appointment of the Replacement Investor Designee to the Board, such Replacement Investor Designee will be considered the Investor Designee for all purposes of this Agreement.

(ii) If any New Independent Director is unable or unwilling to serve as a director, resigns as a director, is removed as a director, or ceases to be a director for any other reason prior to the expiration of the Cooperation Period, the Company and the Elliott Parties shall cooperate in good faith to identify and mutually agree, subject to Sections 1(e) and 1(f), upon a substitute Qualified Director (the “Replacement New Independent Director” and together with any Replacement Investor Designee, the “Replacement New Directors”), and the Board shall take such actions as are necessary to appoint the Replacement New Independent Director to serve as a director of the Company for the remainder of such New Independent Director’s term. Effective upon the appointment of the Replacement New Independent Director to the Board, such Replacement New Independent Director will be considered a New Independent Director for all purposes of this Agreement.

(iii) The Elliott Parties’ rights pursuant to this Section 1(d) are subject to the Elliott Parties’ beneficially holding a Net Long Position equal to, or having aggregate net long economic exposure to, at least 2.0% of the then-outstanding Common Stock (the “Minimum Ownership Threshold”). In the event the Elliott Parties seek to exercise their rights pursuant to this Section 1(d), the Elliott Parties shall certify in writing to the Company that the Minimum Ownership Threshold is satisfied as of the time of such exercise.

(e) Replacement New Director Information. The Elliott Parties acknowledge, as a condition to any Replacement New Director’s appointment to the Board, such individual shall have promptly provided to the Company (i) any consent and information the Company reasonably requests in connection with such appointment, including completion of the Company’s standard forms, D&O questionnaires and other customary onboarding and/or nomination documentation, and an executed consent to be named as a nominee in the Company’s proxy statement and to serve as a director if so elected for the full term for which such individual is elected at any Company meeting of stockholders, in each case, as provided by the Company, (ii) information requested by the Company that is required to be disclosed in a proxy statement

2

or other filing under any applicable law, stock exchange rule, or listing standard, or as may be requested or required by any regulatory or governmental authority having jurisdiction over the Company or its Affiliates, (iii) information reasonably requested by the Company in connection with assessing eligibility, independence, and other criteria applicable to directors or satisfying compliance and legal obligations, (iv) any written consent reasonably requested by the Company for the conduct of the Company’s vetting procedures generally applicable to non-management directors of the Company, and (v) such other information reasonably requested by the Company, including such information as is necessary or appropriate for the Company or its agents to perform a background check in the manner generally performed for non-management directors of the Company, including any one or more executed consents to such background check and the execution of any one or more documents required by the Company of non-management directors of the Company to assure compliance with Section 1(d) and 1(f).

(f) Company Policies. The parties acknowledge that each New Director, upon election or appointment to the Board, will be governed by the same protections and obligations regarding confidentiality, conflicts of interest, related person transactions, fiduciary duties, codes of conduct, trading, and disclosure policies, director resignation policy, stock ownership guidelines, and other governance guidelines and policies of the Company as other directors of the Company (collectively, “Company Policies”), and, except as may be subsequently waived by the Elliott Parties in writing, shall have the same rights and benefits, including with respect to insurance, indemnification, compensation, and fees, as are applicable to all non-management directors of the Company. The Company acknowledges that (i) no Company Policy shall be violated by the Investor Designee receiving indemnification and/or reimbursement of expenses from the Elliott Parties or their respective Affiliates, provided that the Investor Designee neither accepts nor receives compensation from the Elliott Parties or their respective Affiliates with respect to the Investor Designee’s service or action as a director of the Company, (ii) the Company Policies do not apply to the Elliott Parties and their Affiliates as a result of Mr. Barg’s appointment to, or service on, the Board, including Company Policies with respect to trading in the Company’s securities, as they are not directors or employees of the Company, and (iii) no Company Policy currently does, and no Company Policy at any time during the Cooperation Period will, prohibit any member of the Board (including any New Director) from communicating with the Elliott Parties or their Representatives, subject to such director’s observance of standard confidentiality obligations (or in the case of Mr. Barg, subject to the Confidentiality Agreement) and fiduciary duties to the Company. Mr. Barg may provide confidential information of the Company to the Elliott Parties for the purpose of assisting Mr. Barg in his role as a director of the Company and related compliance matters for the Company and the Elliott Parties, subject to, and solely in accordance with the terms of, a customary confidentiality agreement that the Elliott Parties and the Company are entering into simultaneously with this Agreement (the “Confidentiality Agreement”).

(g) Formation of Ad Hoc Strategic and Operational Review Committee. As soon as reasonably practicable following the Effective Date (but in no event later than five (5) Business Days thereafter), the Board shall take all action necessary to form an ad hoc Strategic and Operational Review Committee of the Board (the “Committee”) that will support the Board and management as set forth in the Committee’s charter, which shall be in the form attached to this Agreement as Exhibit A (the “Committee Charter”). As soon as reasonably practicable following the appointment of all the New Directors and through the Cooperation Period, the

3

Committee shall consist of five (5) directors, who shall initially be Steven Barg, John Greisch, Gregory T. Lucier, Michelle R. Ryan, and Jack Stahl. John Greisch will be the initial Chair of the Committee. Any proposed change to the Committee Charter prior to the end of the Cooperation Period will require the prior written consent of the Elliott Parties (such consent not to be unreasonably withheld, conditioned, or delayed). If any New Director is unable or unwilling to serve as a member of the Committee, resigns as a member, is removed as a member or ceases to be a member for any other reason prior to the end of the Cooperation Period, the Elliott Parties shall be entitled to select, in consultation with the Company and as approved by the Board (such approval not to be unreasonably withheld, conditioned, or delayed), a director serving on the Board at the time of such selection (including a Replacement New Director appointed pursuant to Section 1(d)) to serve on the Committee as a replacement for such member (the “Replacement Committee Member”), provided that such Company consultation and Board approval shall not be required for a Replacement Investor Designee selected by the Elliott Parties to serve as a Replacement Committee Member for the Investor Designee. Effective upon the appointment of the Replacement Committee Member to the Committee, such Replacement Committee Member will be considered a “New Director” solely for the purposes of the immediately preceding sentence. The Committee shall continue in existence until the expiration of the Cooperation Period, or such later date as may be determined by the Chair of the Committee following consultation with the Board.

(h) Executive Chair of the Board. As promptly as practicable following the Effective Date, the Board and all applicable committees thereof shall take (or shall have taken) such actions as are necessary to appoint John Greisch as Executive Chair of the Board.

(i) Board Size. Notwithstanding anything to the contrary, (i) from immediately prior to the appointment of the New Directors until the commencement of the 2023 Annual Meeting, the size of the Board shall be no greater than sixteen (16) members, and (ii) from the closing of the 2023 Annual Meeting until the Company’s 2024 annual meeting of stockholders, the size of the Board shall be no greater than twelve (12) members.

(j) 2023 Annual Meeting. The Company shall use its reasonable efforts to hold the 2023 Annual Meeting no later than November 3, 2023, subject to any delay necessitated by compliance with applicable law or regulatory or judicial or stock exchange order, published interpretation or requirement.

(k) Termination. The Company’s obligations under this Section 1 shall terminate upon the earlier of: (i) such time as the Elliott Parties cease to satisfy the Minimum Ownership Threshold, (ii) any material breach of this Agreement (including Section 2) by any Elliott Party or other Restricted Person (treating, for this purpose only, a Restricted Person as though they were a party to this Agreement) upon five (5) Business Days’ written notice by the Company to the Elliott Parties if such breach has not been cured by the end of such notice period; provided that the Company is not in material breach of this Agreement at the time such notice is given or during the notice period, (iii) such time as the Investor Designee notifies the Company of his or her intent to resign from the Board and the Elliott Parties irrevocably waive in writing any right to have a Replacement Investor Designee appointed, or (iv) the Elliott Parties or any other Restricted Person submits any director nomination for election at any meeting of the Company’s stockholders. Upon the occurrence of an event described in clause (iv) of this Section 1(k), the Investor Designee shall promptly offer to resign from the Board (and, if requested by the Company, promptly deliver his or her written resignation to the Board for his or her immediate resignation), subject to the Board’s decision in its sole discretion whether to accept or reject such resignation.

Section 2. Cooperation.

(a) Non-Disparagement. From the execution of this Agreement until the later of (i) the date that is thirty (30) calendar days prior to the notice deadline under the Company’s Bylaws for the nomination of non-proxy access director candidates for election to the Board at the Company’s 2024 Annual Meeting of Stockholders and (ii) the Expiration Time (such period, the “Cooperation Period”), the Company and each Elliott Party shall refrain from making, and shall cause its respective Controlling and Controlled Affiliates (and those under common Control) and each of its and their respective principals, directors, members, general partners, officers and employees (collectively, “Covered Persons”) not to make or cause to be made any public written or oral statement or announcement (including any statement or announcement that can reasonably be expected to become public) (each, a “Statement”) that constitutes an ad hominem attack on, or that otherwise disparages, defames, impugns, or is reasonably likely to damage the reputation of (i) in the case of any Statement by any of the Elliott Parties or their Covered Persons: the Company, any of its Affiliates or any of its or their respective current or former Covered Persons; and (ii) in the case of any Statement by the Company or its Covered Persons: any of the Elliott Parties, any of their respective Affiliates or any of their respective current or former Covered Persons, in each case including (A) in any statement, document, or report filed with, furnished to, or otherwise provided to the SEC or any other governmental or regulatory authority, (B) in any press release or other publicly available format, and (C) to any journalist or member of the media (including in a television, radio, newspaper, or magazine interview, podcast or Internet or social media communication).

other proposals or business that may be the subject of stockholder action; provided, however, that the Elliott Parties and their Affiliates shall be permitted to vote in their sole discretion on any proposal with respect to any Extraordinary Transaction; provided, further, that, in the event that both Institutional Shareholder Services and Glass Lewis & Co. (including any successors thereof) issue a voting recommendation that differs from the voting recommendation of the Board with respect to any Company-sponsored proposal submitted to stockholders at a stockholder meeting (other than with respect to the election of directors to the Board, the removal of directors from the Board, the size of the Board or the filling of any vacancy on the Board), the Elliott Parties and their Affiliates shall be permitted to vote in accordance with any such recommendation.

(c) Standstill.
