AGREEMENT AND PLAN OF REORGANIZATION

This Agreement and Plan of Reorganization (“Agreement”) is made as of September 8, 2023 by and between The MainStay Funds, a Massachusetts business trust(“MSF”), on behalf of its series, the MainStay MacKay International Equity Fund (the “Acquired Fund”), and MainStay Funds Trust, a Delaware statutory trust (“MFT”), on behalf of its series, the MainStay PineStone International Equity Fund (the “Acquiring Fund” and, together with the Acquired Fund, the “Funds”).

This Agreement is intended to be and is adopted as a “plan of reorganization” within the meaning of Section 368(a)(1) of the Internal Revenue Code of 1986, as amended (the “Code”). The reorganization will consist of the transfer of all of the assets of the Acquired Fund to the Acquiring Fund in exchange solely for Class A, Investor Class, Class C, Class I, Class R1, Class R2, Class R3 and Class R6 shares of beneficial interest of the Acquiring Fund (the “Acquiring Fund Shares”), the assumption by the Acquiring Fund of all liabilities of the Acquired Fund, and the distribution, upon the Closing Date (as defined in paragraph 3.1), of the Acquiring Fund Shares to the shareholders of the Acquired Fund in complete liquidation of the Acquired Fund, all upon the terms and conditions hereinafter set forth in this Agreement (the “Reorganization”).

The Board of Trustees of MSF has determined, with respect to the Acquired Fund, that (1) participation in the Reorganization is in the best interests of the Acquired Fund and its shareholders, and (2) the interests of the existing shareholders of the Acquired Fund would not be diluted as a result of the Reorganization. The Board of Trustees of MFT has determined, with respect to the Acquiring Fund, that (1) participation in the Reorganization is in the best interests of the Acquiring Fund and its shareholders, and (2) the interests of the existing shareholders of the Acquiring Fund would not be diluted as a result of the Reorganization.

NOW, THEREFORE, in consideration of the premises and of the covenants and agreements hereinafter set forth, the parties hereto covenant and agree as follows:

ARTICLE I

THE REORGANIZATION AND FUND TRANSACTIONS

1.1. The Reorganization. Subject to the requisite approval of the Acquired Fund’s shareholders and the other terms and conditions herein set forth and on the basis of the representations and warranties contained herein, at the Effective Time (as defined in paragraph 2.4), MFT shall assign, deliver and otherwise transfer the Assets (as defined in paragraph 1.2) of the Acquired Fund to MFT on behalf of the Acquiring Fund. In consideration of the foregoing, at the Effective Time, MFT shall, on behalf of the Acquiring Fund, deliver to MSF, on behalf of the Acquired Fund, full and fractional Acquiring Fund Shares, and MFT shall assume the Liabilities (as defined in paragraph 1.3) of the Acquired Fund on behalf of the Acquiring Fund. The number of Acquiring Fund Shares to be delivered shall be determined as set forth in paragraph 2.3.

1.2. Assets of the Acquired Fund. The assets of the Acquired Fund to be transferred to the Acquiring Fund shall consist of all assets and property, including, without limitation, all cash, cash equivalents, securities, receivables (including securities, interests and dividends receivable), commodities and futures interests, rights to register shares under applicable securities laws, all rights of the Acquired Fund, any known or unknown class action claims outstanding as of the Effective Time that become payable after the Effective Time, any deferred or prepaid expenses shown as an asset on the books of the Acquired Fund at the Effective Time, books and records and any other property owned by the Acquired Fund at the Effective Time (collectively, the “Assets”). Notwithstanding the foregoing, copies of the applicable books and records may be retained as required by applicable law or as necessary for the Acquired Fund or MSF on behalf of the Acquired Fund to prepare and file Tax Returns pursuant to paragraph 5.14 of this Agreement.

1.3. Liabilities of the Acquired Fund. The Acquired Fund will use commercially reasonable efforts to discharge its known liabilities and obligations prior to the Effective Time, other than liabilities and obligations necessary or appropriate for the Acquired Fund’s normal investment operations that are incurred in the ordinary course of business consistent with past practice. The Acquiring Fund shall assume all liabilities, obligations and debts of the Acquired Fund, whether known or unknown, absolute or contingent, accrued or unaccrued, existing at the Effective Time (collectively, the “Liabilities”).

1.4. Distribution of Acquiring Fund Shares. At the Closing (as defined below) (or as soon thereafter as is reasonably practicable), MSF, on behalf of the Acquired Fund, will distribute the Acquiring Fund Shares received from MFT pursuant to paragraph 1.1, pro rata to the record holders of the shares of the Acquired Fund determined as of the Effective Time (the “Acquired Fund Shareholders”) in complete liquidation of the Acquired Fund. Holders of Class A, Investor Class, Class C, Class I, Class R1, Class R2, Class R3 and Class R6 shares of the Acquired Fund will receive Class A, Investor Class, Class C, Class I, Class R1, Class R2, Class R3 and Class R6 shares of the Acquiring Fund. Such distribution and liquidation will be accomplished by the transfer of the Acquiring Fund Shares then credited to the account of the Acquired Fund on the books of the Acquiring Fund to open accounts on the share records of the Acquiring Fund in the names of the Acquired Fund Shareholders. The aggregate net asset value of the Acquiring Fund Shares to be so credited to Acquired Fund Shareholders shall be equal to the aggregate net asset value of the then outstanding shares of beneficial interest of the Acquired Fund (the “Acquired Fund Shares”) owned by Acquired Fund Shareholders at the Effective Time. All issued and outstanding Acquired Fund Shares will simultaneously be redeemed and canceled on the books of the Acquired Fund. The Acquiring Fund shall not issue certificates representing the Acquiring Fund Shares in connection with such exchange.

1.5. Recorded Ownership of Acquiring Fund Shares. Ownership of Acquiring Fund Shares by the Acquired Fund Shareholders will be shown on the books of the Acquiring Fund’s transfer agent.

1.7. Termination of Acquired Fund. The Acquired Fund will have its affairs wound up and be terminated as a separate series of MSF in accordance with applicable law as soon as practicable following the Closing and the making of the distributions pursuant to paragraph 1.4.

CLOSING

3.1. Closing. The Reorganization, together with related acts necessary to consummate the same (“Closing”), shall occur at the principal office of New York Life Investments on or about September 8, 2023, or by facsimile, email or other communication, at such other place and/or on such other date as to which the parties may agree (the “Closing Date”).

Such presentation, if applicable, shall be made for examination no later than five (5) business days preceding the Effective Time, and shall be transferred and delivered by the Acquired Fund as of the Effective Time for the account of the Acquiring Fund duly endorsed in proper form for transfer in such condition as to constitute good delivery thereof. JPM shall deliver to those persons at JPM who have primary responsibility for the safekeeping of the assets of the Acquiring Fund as of the Effective Time by book entry, in accordance with the customary practices of JPMorgan and of each securities depository, as defined in Rule 17f-4 under the Investment Company Act of 1940, as amended (the “1940 Act”), in which the Assets are deposited, the Assets deposited with such depositories. The cash to be transferred by the Acquired Fund shall be delivered to JPMorgan or as instructed by MSF by wire transfer of federal funds at the Effective Time. To the extent that any Assets of the Acquired Fund, for any reason, are not transferable to the Acquiring Fund on the Closing Date, the Acquired Fund shall cause such Assets to be transferred to the Acquiring Fund’s account with JPMorgan at the earliest practicable date thereafter.

An officer of the Acquiring Fund shall issue and deliver to the Secretary of the Acquired Fund prior to the Effective

Time a confirmation evidencing that the appropriate number of Acquiring Fund Shares will be credited to the Acquired Fund at the Effective Time, or provide other evidence reasonably satisfactory to the Acquired Fund as of the Effective Time that such Acquiring Fund Shares have been credited to the Acquired Fund’s accounts on the books of the Acquiring Fund.

3.4. Postponement of Effective Time. In the event that, at the Effective Time, (a) the NYSE or another primary trading market for portfolio securities of the Acquiring Fund or the Acquired Fund (each, an “Exchange”) shall be closed to trading or trading thereupon shall be restricted, or (b) trading or the reporting of trading on such Exchange or elsewhere shall be disrupted so that, in the judgment of the Board of Trustees of MSF or the Board of Trustees of MFT, accurate appraisal of the value of the assets of the Acquired Fund or the Acquiring Fund, respectively, is impracticable, the Effective Time shall be postponed until the first business day after the day when trading shall have been fully resumed and reporting shall have been restored.

(e) At the Effective Time, MSF, on behalf of the Acquired Fund, will have good and marketable title to the Assets and full right, power, and authority to sell, assign, transfer and deliver such Assets hereunder free of any liens or other encumbrances, and upon delivery and payment for such Assets, MFT, on behalf of the Acquiring Fund, will acquire good and marketable title thereto, subject to no restrictions on the full transfer thereof, including such restrictions as might arise under the 1933 Act; provided, however, that certain Assets may be pledged, segregated or earmarked against the Acquired Fund’s investment contracts, including options, futures, forward contracts and other similar instruments, in accordance with the terms of such contracts or applicable interpretations of the Commission staff.

(f) MSF, on behalf of the Acquired Fund, is not engaged currently, and the execution, delivery and performance of this Agreement will not result, in (i) a material violation of Massachusetts law or of its Declaration of Trust and By-Laws, or a material breach of any agreement, indenture, instrument, contract, lease or other undertaking to which MSF, on behalf of the Acquired Fund, is a party or by which it is bound, or (ii) the acceleration of any material obligation, or the imposition of any material penalty, under any agreement, indenture, instrument, contract, lease, judgment or decree to which MSF, on behalf of the Acquired Fund, is a party or by which it is bound.

(1) The transfer by the Acquired Fund of all of its Assets to the Acquiring Fund in exchange solely for Acquiring Fund Shares and the assumption by the Acquiring Fund of all the Liabilities of the Acquired Fund, followed by the distribution of such shares to the Acquired Fund Shareholders in complete liquidation of the Acquired Fund, will constitute a reorganization under Section 368(a)(1) of the Code and the Acquired Fund and the Acquiring Fund will each be “a party to a reorganization” within the meaning of Section 368(b) of the Code.

(2) No gain or loss will be recognized by the Acquired Fund upon the transfer of the Acquired Fund’s Assets to the Acquiring Fund solely in exchange for Acquiring Fund Shares and the assumption by the Acquiring Fund of the Acquired Fund’s Liabilities, or upon the distribution (whether actual or constructive) by the Acquired Fund of such Acquiring Fund Shares to the Acquired Fund Shareholders in liquidation, except that the Acquired Fund may be required to recognize gain or loss with respect to: (A) contracts described in Section 1256(b) of the Code; (B) stock in a passive foreign investment company, as defined in Section 1297(a) of the Code; or (C) any other gain or loss required to be recognized upon the termination of a position, or upon the transfer of such asset regardless of whether such a transfer would otherwise be a nontaxable transaction under the Code.

(3) No gain or loss will be recognized by the Acquiring Fund upon the receipt of the Acquired Fund’s Assets solely in exchange for Acquiring Fund Shares and the assumption by the Acquiring Fund of the Acquired Fund’s Liabilities.

(4) No gain or loss will be recognized by the Acquired Fund Shareholders upon the distribution to them by the Acquired Fund of the Acquiring Fund Shares solely in exchange for their Acquired Fund Shares as part of the Reorganization.

(5) The basis of the Acquiring Fund Shares received by each Acquired Fund Shareholder in the Reorganization will be the same as the basis of the shareholder’s Acquired Fund Shares exchanged therefor.

(6) The basis of the Acquired Fund’s Assets received by the Acquiring Fund in the Reorganization will be the same as the basis of the Acquired Fund’s Assets in the hands of the Acquired Fund immediately prior to the transfer, adjusted for any gain or loss required to be recognized in paragraph (2) above.

(7) The holding period for the Acquiring Fund Shares received by each Acquired Fund Shareholder in the Reorganization will include the period for which the shareholder held the Acquired Fund Shares exchanged therefor, provided that the shareholder held such Acquired Fund Shares as a capital asset at the time of the exchange.

(8) The holding period of the Acquired Fund’s Assets in the hands of the Acquiring Fund will include the period for which the Acquired Fund’s Assets were held by the Acquired Fund (except where investment activities of the Acquiring Fund have the effect of reducing or eliminating a holding period with respect to an Asset and except for any asset with respect to which gain or loss is required to be recognized as described in paragraph (2) above ).

(9) The Acquiring Fund will succeed to and take into account those tax attributes of the Acquired Fund that are described in Section 381(c) of the Code, subject to the conditions and limitations specified in the Code, the regulations thereunder, and existing court decisions and published interpretations of the Code and regulations.

The delivery of such opinion is conditioned upon receipt by Dechert LLP of representations requested of MSF and the MFT on behalf of the Acquired Fund and the Acquiring Fund, respectively.
