Ladies and Gentlemen:

This opinion is being furnished in connection with the Registration Statement on Form N-14 (the “Registration Statement”) being filed today by The Prudential Series Fund (the “Trust”) under the Securities Act of 1933, as amended (the “Act”), relating to the proposed acquisition by PSF PGIM Jennison Blend Portfolio, a series of the Trust (the “Acquiring Fund”), of all the assets and liabilities of PSF PGIM Jennison Focused Blend Portfolio, a series of the Trust (the “Acquired Fund”), and the issuance of Class I, Class II, and Class III shares of beneficial interest of the Acquiring Fund in connection therewith (collectively, the “Shares”), all in accordance with the terms of the Plan of Reorganization, by and among the Trust, on behalf of the Acquiring Fund, and the Trust, on behalf of the Acquired Fund (the “Plan of Reorganization”), in substantially the form included as Appendix A to the prospectus/information statement that is part of the Registration Statement.

We are familiar with the actions taken by the Trustees of the Trust to authorize the issuance of Shares. In connection with this opinion, we have examined such certificates, documents, and records and have made such investigation of fact and such examination of law as we have deemed appropriate in order to enable us to render the opinion set forth herein. In conducting such investigation, we have relied, without independent verification, upon certificates of officers of the Trust, public officials and other appropriate persons. We assume that, upon the delivery of the Shares by the Trust in accordance with the terms of the Plan of Reorganization, the Trust will receive the net asset value thereof.

We have assumed, for the purposes of this opinion, that, prior to the date of the issuance of the Shares, the Plan of Reorganization will have been duly executed and delivered by each party thereto in the form included as Appendix A to the prospectus/information statement that is part of the Registration Statement and will constitute a legal, valid, and binding obligation of the Trust, on behalf of the Acquiring Fund.

In rendering the opinion expressed herein, we have, with your approval, relied solely on the opinion, dated the date hereof, of Morris, Nichols, Arsht & Tunnell LLP. insofar as such opinion relates to the laws of the State of Delaware (subject to all of the assumptions and qualifications to which such opinion is subject), and we have made no independent examination of the laws of that jurisdiction. We are providing a copy of that opinion together with this opinion.

Based upon and subject to the foregoing, we are of the opinion that the Trust is authorized to issue the Shares, and that, when such Shares are issued and delivered in accordance with the terms of the Plan of Reorganization, such Shares will be validly issued, fully paid, and nonassessable by the Trust.

We hereby consent to the filing of this opinion as an exhibit to Registration Statement and to the references to our firm as legal counsel for the Trust in the Registration Statement. This consent shall not constitute an acknowledgment that we are within the category of persons whose consent is required by Section 7 of the Securities Act of 1933, as amended, and the rules and regulations thereunder.

Very truly yours,

/s/ Ropes & Gray LLP

In rendering this opinion, we have examined and relied on copies of the following documents, each in the form provided to us: the Plan; the Trust’s Registration Statement on Form N-14 to be filed with the Securities and Exchange Commission on or about the date hereof, to which the Plan is attached as an exhibit (the “Registration Statement”); the Certificate of Trust of the Trust as filed in the Office of the Secretary of State of the State of Delaware (the “State Office”) on September 9, 2005 (the “Certificate”); the Agreement and Declaration of Trust of the Trust dated September 8, 2005 (the “Governing Instrument”); the By-laws of the Trust (the “By-laws”); resolutions adopted at a meeting of the Trustees of the Trust held on September 19-20, 2023 relating to the approval and authorization of the Plan by the Trustees of the Trust (the “Authorizing Resolutions” and collectively with the Registration Statement, the Governing Instrument and the By-laws, the “Governing Documents”); and a certification of good standing of the Trust obtained as of a recent date from the State Office. In such examinations, we have assumed the genuineness of all signatures, the conformity to original documents of all documents submitted to us as copies or drafts of documents to be executed, and the legal capacity of natural persons to complete the execution of documents. We have further assumed for purposes of this opinion: (i) the due formation or organization, valid existence and good standing, as applicable, of the Acquiring Fund and each other person or entity that is a party to any of the documents reviewed by us under the laws of the jurisdiction of its respective formation or organization (other than the Trust); (ii) the due adoption, authorization, execution and delivery by, or on behalf of, each of the parties thereto of the above-referenced agreements, instruments, certificates and other documents and of all documents contemplated by the Governing Documents to be executed by investors desiring to become Shareholders; (iii) the payment of consideration for Shares, and the application of such consideration, as provided in the Governing Documents and the Plan, the satisfaction of all conditions precedent to the issuance of Shares pursuant to the Plan and compliance with all other terms, conditions and restrictions set forth in the Plan and the Governing Documents in connection with the issuance of Shares under the Plan; (iv) that appropriate notation of the names and addresses of, the number of Shares held by, and the consideration paid by, Shareholders will be maintained in the appropriate registers and other books and records of the Trust in connection with the issuance, redemption or transfer of Shares; (v) that, subsequent to the filing of the Certificate, no event has occurred, or prior to the issuance of the Shares pursuant to the Plan will occur, that would cause a termination, dissolution or reorganization of the Trust under Sections 2 or 3 of Article IX of the Governing Instrument; (vi) that, subsequent to the filing of the Certificate, no event has occurred, or prior to the issuance of the Shares pursuant to the Plan will occur, that would cause a termination, dissolution or reorganization of the Acquiring Fund under Section 6 of Article III or Sections 2 or 3 of Article IX of the Governing Instrument; (vii) that the Trust became, prior to or within 180 days following the first issuance of beneficial interests therein, a registered investment company under the Investment Company Act of 1940, as amended; (viii) that the activities of the Trust have been and will be conducted in accordance with the terms of the Governing Instrument and the Delaware Statutory Trust Act, 12 Del. C. §§ 3801 et seq.; and (ix) that each of the documents examined by us is in full force and effect, expresses the entire understanding of the parties thereto with respect to the subject matter thereof and has not been amended, supplemented or otherwise modified, except as herein referenced. We have not reviewed any documents other than those identified above in connection with this opinion, and we have assumed that there are no documents, facts or circumstances that are contrary to or inconsistent with the opinions expressed herein. No opinion is expressed herein with respect to the requirements of, or compliance with, federal or state securities or blue sky laws.
