I. NEWSUB-ADVISORY AGREEMENTS

The Funds follow a sustainable investing approach that aligns with environmental, social and governance (“ESG”) principles and values. Consistent with each Fund’s multi-disciplinary approach, the ESG strategies used by the Funds may vary across the Funds’ underlying funds and separately managed segments. Natixis Advisors acts as the Funds’ investment adviser pursuant to the Advisory Agreement and has overall supervisory responsibility for the general management and investment of each Fund’s assets. A third partysub-adviser, Wilshire Associates Incorporated (“Wilshire”), developed each Fund’s glide path and determines the target allocations among the Fund’s affiliated underlying funds and separately managed segments. Natixis Advisors and Wilshire believe that the addition of the NewSub-Strategies will further diversify the Funds’ exposures, reduce current manager concentration and better position the Funds in the marketplace by incorporating some of Natixis Advisors’ premier actively managed strategies.

Description of the NewSub-Strategies

The Funds were launched in February 2017 as the industry’s first series of target date funds with an ESG focus. Until recently, the Funds allocated their assets among investments in affiliated underlying funds and segments managed directly by Natixis Advisors orsub-advised by Mirova US LLC (“Mirova”) (formerly, Ostrum Asset Management U.S., LLC), an affiliate of Natixis Advisors. Subsequently, Natixis Advisors and Wilshire identified an opportunity to further diversify the Funds’ exposures and enhance the Funds’ position in the marketplace by adding three new segments to besub-advised by Harris Associates and Loomis Sayles, each a wholly-owned subsidiary of Natixis Advisors. The NewSub-Advisers are well-regarded managers that integrate an evaluation of ESG factors into their investment processes. Natixis Advisors believes that the addition of the NewSub-Strategies will improve the quality of the underlying investment strategies in the Funds.

Effective April 30, 2019, each Fund’s principal investment strategies now include the following NewSub-Strategies:

• The U.S equity allocation now includes theHarris Associates Large Cap Value Segment, which will invest in a fairly focused portfolio(30-60 stocks) ofmid- andlarge-cap companies based in the United States. In building the portfolio, the team focuses on stocks of companies that they believe are trading at a significant discount to intrinsic value, are expected to grow in shareholder value over time, and companies that feature shareholder-oriented management.

• Additionally, the U.S. equity allocation now includes theLoomis Sayles All Cap Growth Segment, which seeks to invest in a concentrated portfolio(30-40 stocks) of high quality businesses with sustainable competitive advantages and profitable growth when they trade at a significant discount to intrinsic value.

3

• The fixed-income allocation now includes theLoomis Sayles Core Fixed Income Segment. To achieve its objective, the team utilizes the complete range of insights generated by the Loomis Sayles fixed income organization to identify high potential relative return investment ideas in the investment grade portion of the U.S. fixed income markets.

At a meeting held on March 7, 2019, the Board approved the NewSub-Advisory Agreements with Harris Associates and Loomis Sayles in order to effectuate the investment strategy changes described above. The NewSub-Advisory Agreements are substantially identical to the existingsub-advisory agreement among the Trust, on behalf of the Funds, Natixis Advisors and Mirova. Please see further information below under “Description of the NewSub-Advisory Agreements.” In considering the NewSub-Advisory Agreements, the Board received information regarding the services to be provided by Harris Associates and Loomis Sayles, including presentations by portfolio managers from each NewSub-Advisor on how they would integrate ESG factors into the investment processes of their strategies. Please see further information below under “Consideration of NewSub-Advisory Agreements by the Trustees.”

Under the terms of the Advisory Agreement and the Order, the Funds may add additional segments to be managed by either Natixis Advisors or a wholly-owned or unaffiliatedsub-adviser in the future, provided that the advisory fee rates applicable to such segments do not exceed the maximum advisory fee rates set forth in the Advisory Agreement (0.25% of the average daily net assets of any segment managed directly by Natixis Advisors and 0.70% of the average daily net assets of any segment managed by anysub-adviser other than Wilshire). The NewSub-Advisory Agreements do not affect the maximum aggregate advisory fee rates payable by the Funds set forth in the Advisory Agreement.

Description of the NewSub-Advisory Agreements

Copies of the NewSub-Advisory Agreements are set forth as AppendicesA-1 andA-2 to this Information Statement. The following descriptions of the NewSub-Advisory Agreements are qualified in their entirety by reference to the full text of the NewSub-Advisory Agreements as set forth in AppendicesA-1 andA-2.

The NewSub-Advisory Agreements, which took effect on April 30, 2019, require Harris Associates and Loomis Sayles to manage the investment and reinvestment of such portion of the assets of each Fund as Natixis Advisors or its designee may from time to time allocate to Harris Associates or Loomis Sayles for management (each a “Segment” and, collectively, the “Segments”). The NewSub-Advisory Agreements provide that each NewSub-Advisor shall be paid at an annual rate not to exceed 0.70% of the average daily net assets of each Segment of the Funds (or such lesser amount as the NewSub-Adviser may from time to time agree to receive).

4

The NewSub-Advisory Agreements provide that they will continue in effect for two years from their date of execution and thereafter from year to year if their continuance is approved at least annually (i) by the Board or by vote of a majority of the outstanding voting securities of the Funds, and (ii) by vote of a majority of the Trustees who are not “interested persons,” as that term is defined in the 1940 Act (“Independent Trustees”), of the Trust, Natixis Advisors or the NewSub-Advisers, cast in person at a meeting called for the purpose of voting on such approval. Any amendment to the NewSub-Advisory Agreements must be approved by Natixis Advisors and the NewSub-Advisers and, if required by law, by vote of a majority of the outstanding voting securities of the Funds and by a majority of the Independent Trustees, cast in person at a meeting called for the purpose of voting on such approval. The NewSub-Advisory Agreements may be terminated without penalty by vote of the Board or by vote of a majority of the outstanding voting securities of the Funds, upon 60 days’ written notice to the NewSub- Advisers, or by the NewSub-Advisers or Natixis Advisors upon 90 days’ written notice, and will terminate automatically in the event of their “assignment,” as defined in the 1940 Act.

The NewSub-Advisory Agreements will automatically terminate if the Advisory Agreement is terminated. The NewSub-Advisory Agreements arenon-exclusive with respect to the services of Harris Associates and Loomis Sayles, which means that Harris Associates and Loomis Sayles can serve as advisers to other mutual funds and investment accounts.

The NewSub-Advisory Agreements provide that the NewSub-Advisers shall not be subject to any liability in connection with the performance of their services thereunder in the absence of willful misfeasance, bad faith, gross negligence or reckless disregard of their obligations and duties.

Fees Paid Under theSub-Advisory Agreements

Thesub-advisory fee rate currently paid with respect to the Harris Associates Large Cap Value Segment is 0.52% of the average daily net assets of the Segment. Thesub-advisory fee rates currently paid with respect to the Loomis Sayles All Cap Growth Segment and the Loomis Sayles Core Fixed Income Segment are 0.35% and 0.20%, respectively, of the average daily net assets of such Segments. As noted above, the NewSub-Advisory Agreements do not affect the maximum aggregate advisory fee rates payable by the Funds set forth in the Advisory Agreement (0.25% of the average daily net assets of any segment managed directly by Natixis Advisors and 0.70% of the average daily net assets of any segment managed by anysub-adviser other than Wilshire).

Because Harris Associates and Loomis Sayles were appointed assub-advisers effective April 30, 2019, they did not receivesub-advisory fees for the fiscal year ended January 31, 2019.

Consideration of NewSub-Advisory Agreements by the Trustees

Natixis Advisors recommended the appointment of Harris Associates and Loomis Sayles to manage the NewSub-Strategies, effective April 30, 2019. The Board considered the NewSub- Advisory Agreements at their meeting held on March 7, 2019. The Trustees considered the

5

NewSub-Advisory Agreements in connection with the addition of the NewSub-Strategies. In considering whether to approve the NewSub-Advisory Agreements, the Trustees noted that Natixis Advisors, the entity that serves as the Funds’ investment adviser under a “manager of managers” structure, was recommending the addition of the NewSub-Advisers and the approval of the NewSub-Advisory Agreements was in the best interest of the Funds. In considering whether to approve the NewSub-Advisory Agreements, the Board, including the Independent Trustees, did not identify any single factor as determinative. Matters considered by the Trustees, including the Independent Trustees, in connection with their approval of the NewSub-Advisory Agreements included the following:

The nature, extent and quality of the services to be provided to the Funds under the NewSub- Advisory Agreements.The Trustees considered the nature, extent and quality of the services Harris Associates and Loomis Sayles are believed to be capable of providing to the Funds and the resources expected to be dedicated to the Funds by Harris Associates and Loomis Sayles. The Trustees met with senior representatives of Harris Associates and Loomis Sayles, who presented extensive information regarding their respective experience, capabilities and investment management process and philosophy. The Trustees noted that Harris Associates managed $107 billion in assets as of December 31, 2018 for other mutual funds as well as assets of individual trusts, retirement plans, endowments, foundations, and several private partnerships. The Trustees also noted that Loomis Sayles had over $249.7 billion in assets under management as of December 31, 2018. Therefore, the Trustees determined that each NewSub- Adviser is familiar with the demands of managing mutual fund assets. After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the NewSub-Advisory Agreements, that the nature, extent and quality of services expected to be provided supported the approval of the NewSub-Advisory Agreements.

Investment performance of Harris Associates and Loomis Sayles.The Trustees received information about the performance of accounts managed by Harris Associates and Loomis Sayles, including information which compared the performance of such accounts to the performance of relevant benchmarks. The performance information provided included data for other funds or strategies managed by Harris Associates and Loomis Sayles (in the style of the segments of the Funds to be managed by Harris Associates and Loomis Sayles) and for other accounts managed by applying similar investing approaches to stocks of different capitalization ranges.

After reviewing the information, the Board concluded that the performance of Harris Associates and Loomis Sayles in managing other accounts supported the approval of the NewSub- Advisory Agreements. The Trustees also considered Harris Associates’ and Loomis Sayles’ performance and reputation generally.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the NewSub-Advisory Agreements, that the performance of Harris Associates and Loomis Sayles supported the approval of the NewSub-Advisory Agreements.

6

The costs of the services to be provided and profits to be realized by Natixis Advisors and its affiliates from their respective relationships with the Funds.The Trustees considered the fees charged to the Funds for advisory,sub-advisory and administrative services, as well as the total expense levels of the Funds.

This information included comparisons (provided both by management and also by an independent third party) of the Funds’ advisory andsub-advisory fees and total expense levels to those of their peer groups of mutual funds and information about the advisory andsub-advisory fees and total expense levels to those of their peer groups and information about the advisory fees charged by Natixis Advisors and the Funds’sub-advisers (including Harris Associates and Loomis Sayles) to comparable accounts (such as institutional separate accounts), as well as information about differences in such fees and the reasons for any such differences. In considering the fees charged to comparable accounts, the Trustees considered, among other things, management’s representations about the differences between managing mutual funds as compared to other types of accounts, including the additional resources required to effectively manage mutual fund assets and the greater regulatory costs associated with the management of such assets. The Trustees also took into account the demands, complexity and quality of the investment management of the relevant segments of each Fund.

The Trustees noted that because Harris Associates and Loomis Sayles had not yet begun providing services to the Funds, no historical information was available relating to the profitability to Harris Associates or Loomis Sayles from their relationship to the Funds.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the NewSub-Advisory Agreements, that the advisory andsub-advisory fees charged to each of the Funds (and thesub-advisory fees to be paid to Harris Associates and Loomis Sayles) were fair and reasonable, and that the costs of these services generally supported the approval of the NewSub-Advisory Agreements.

Economies of Scale.The Trustees considered the existence of any economies of scale in the provision of services by Natixis Advisors and the Funds’sub-advisers (including Harris Associates and Loomis Sayles) and whether those economies will be shared with the Funds through breakpoints in their investmentsub-advisory fees or other means, such as expense caps. With respect to economies of scale, the Trustees noted that each of the Funds was subject to an expense cap. In considering these issues, the Trustees also took note of the costs of the services provided (both on an absolute and on a relative basis) and the profitability to Natixis Advisors and its affiliates of their relationships with the Funds, as discussed above.

After reviewing these and related factors, the Trustees considered, within the context of their overall conclusions regarding each of the NewSub-Advisory Agreements, that the extent to which economies of scale will be shared with the Funds supported the approval of the NewSub- Advisory Agreements.

7

The Trustees also considered other factors, which included but were not limited to the following:

• The effect of recent market and economic events on the performance, asset levels and expense ratios of each Fund.

• Whether each Fund has operated in accordance with its investment objective and the Fund’s record of compliance with its investment restrictions, and the compliance programs of the Funds, Natixis Advisors and the NewSub-Advisers. They also considered the compliance-related resources Natixis Advisors and its affiliates were providing to the Funds.

• So-called “fallout benefits” to Natixis Advisors, such as the engagement of affiliates of Natixis Advisors to provide distribution, administrative and brokerage services to the Funds, and the benefits of research made available to Natixis Advisors and the NewSub- Advisers by reason of brokerage commissions (if any) generated by the Funds’ securities transactions. The Trustees also considered the benefits to the parent company of Natixis Advisors from the retention of the NewSub-Advisers. The Trustees considered the possible conflicts of interest associated with these fallout and other benefits, and the reporting, disclosure and other processes in place to disclose and monitor such possible conflicts of interest.

• The Trustees’ review and discussion of the Funds’ advisory arrangements in prior years, and management’s record of responding to Trustee concerns raised during the year and in prior years.

Upon the recommendation of Natixis Advisors, and based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent counsel, the Trustees, including the Independent Trustees, voted to approve each of the NewSub-Advisory Agreements for an initialtwo-year term commencing April 30, 2019.

¹  Such ownership may be beneficially held by individuals or entities other than the owner listed. To the extent that any listed shareholder beneficially owns more than 25% of the Funds, it may be deemed to “control” the Funds within the meaning of the 1940 Act. The effect of such control may be to reduce the ability of other shareholders of the Fund to take actions requiring the affirmative vote of holders of a plurality or majority of the Fund’s shares without the approval of the controlling shareholder.

²  As of May 1, 2019, Natixis Investment Managers, L.P. owned more than 25% of each Fund and therefore may be presumed to “control” each Fund, as that term is defined in the 1940 Act.

15

As of May 31, 2019, the officers and Trustees of the Trust as a group owned less than 1% of the outstanding shares of any class of shares of each Fund.

Shareholder Proposals at Future Meetings

The Trust does not hold annual or other regular meetings of shareholders. Shareholder proposals to be presented at any future meeting of shareholders of the Trust must be received by the Trust a reasonable time before the Trust’s solicitation of proxies for that meeting in order for such proposals to be considered for inclusion in the proxy materials relating to that meeting.

Delivery to Shareholders Sharing an Address

The Trustees are delivering one Information Statement to multiple shareholders sharing an address unless the Trust or Natixis Distribution has received contrary instructions from one or more of such shareholders. Upon written or oral request, Natixis Distribution shall deliver a separate copy of this Information Statement to a shareholder at a shared address to which a single copy of this Information Statement was previously delivered. To find out how to request a separate copy of this Information Statement or any future annual report or information statement or to request delivery of a single copy of annual reports or information statements if they are receiving multiple copies of such documents, shareholders sharing an address with other shareholders may contact Natixis Distribution in writing at 888 Boylston Street, Boston, Massachusetts 02119-8197 or by calling1-800-225-5478.

Sub-Advisory Agreement

(Harris Associates L.P.)

Sub-Advisory Agreement (this “Agreement”) entered into as of this 30th day of April, 2019, by and among Natixis Funds Trust IV, a Massachusetts business trust (the “Trust”), with respect to its series listed in Schedule A (each a “Fund” and, collectively, the “Funds”), Natixis Advisors, L.P., a Delaware limited partnership (the “Manager”), and Harris Associates L.P., a Delaware limited partnership (the“Sub-Adviser”).

WHEREAS, the Manager has entered into an Advisory Agreement dated February 28, 2017 (the “Advisory Agreement”) with the Trust, relating to the provision of portfolio management and administrative services to the Funds;

WHEREAS, the Advisory Agreement provides that the Manager may delegate any or all of its portfolio management responsibilities under the Advisory Agreement to one or moresub-advisers;

WHEREAS, the Manager and the Trustees of the Trust desire to retain theSub-Adviser to render portfolio management services in the manner and on the terms set forth in this Agreement.

NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth in this Agreement, the Trust, the Manager and theSub-Adviser agree as follows:

1.Sub-Advisory Services.

a. TheSub-Adviser shall, subject to the supervision of the Manager and of any administrator appointed by the Manager (the “Administrator”), manage the investment and reinvestment of such portion the assets of each Fund as the Manager or its designee may from time to time allocate to theSub-Adviser for management (each a “Segment” and, collectively, the “Segments”). TheSub- Adviser shall have the authority on behalf of each Fund to vote and shall vote all proxies and exercise all other rights of the Funds as a security holder of companies in which the Segments from time to time invest. TheSub-Adviser shall manage each Segment in conformity with (1) the investment objective, policies and restrictions of the applicable Segment of the applicable Fund set forth in the Trust’s prospectus and statement of additional information relating to the Fund, (2) any additional policies or guidelines established by the Manager or by the Trust’s trustees that have been furnished in writing to theSub-Adviser and (3) the provisions of the Internal Revenue Code as amended (the “Code”) applicable to “regulated investment companies” (as defined in Section 851 of the Code), all as from time to time in effect (collectively, the “Policies”), and with all applicable

1

provisions of law, including without limitation all applicable provisions of the Investment Company Act of 1940, as amended (the “1940 Act”) and the rules and regulations thereunder. For purposes of compliance with the Policies, theSub- Adviser shall be entitled to treat each Segment as though the Segment constituted the entire Fund, and theSub-Adviser shall not be responsible in any way for the compliance of any assets of the Funds, other than the Segments, with the Policies, or for the compliance of the Funds, taken as a whole, with the Policies. For clarification, theSub-Adviser is not responsible for the requirements of the Code or the 1940 Act that Natixis Advisors believes should be monitored for at the Fund level (for example, concentration, diversification and liquidity limits). Subject to the foregoing, theSub-Adviser is authorized, in its discretion and without prior consultation with the Manager, to buy, sell, lend and otherwise trade in any stocks, bonds and other securities and investment instruments on behalf of the Funds, without regard to the length of time the securities have been held and the resulting rate of portfolio turnover or any tax considerations; and the majority or the whole of each Fund may be invested in such proportions of stocks, bonds, other securities or investment instruments, or cash, as theSub-Adviser shall determine. Notwithstanding the foregoing provisions of this Section I .a, however, theSub-Adviser shall, upon written instructions from the Manager, effect such portfolio transactions for a Segment as the Manager shall determine are necessary in order for the applicable Fund to comply with the Policies.

b. TheSub-Adviser shall furnish the Manager and the Administrator monthly, quarterly and annual reports concerning portfolio transactions and performance of the Segments in such form as may be mutually agreed upon, and agrees to review the Segments and discuss the management of the Segments with the Manager and the Administrator. TheSub-Adviser shall permit all books and records with respect to the Segments to be inspected and audited by the Manager and the Administrator at all reasonable times during normal business hours, upon reasonable notice. TheSub-Adviser shall also provide the Manager with such other information and reports as may reasonably be requested by the Manager from time to time, including without limitation all material requested by or required to be delivered to the Trustees of the Trust.

c. TheSub-Adviser shall provide to the Manager a copy of theSub-Adviser’s Form ADV as filed with the Securities and Exchange Commission and a list of the persons whom theSub-Adviser wishes to have authorized to give written and/or oral instructions to custodians of assets of the Funds.

2

2.Obligations of the Manager.

a, The Manager shall provide (or cause the Funds’ Custodian (as defined in Section 3 hereof) to provide) timely information to theSub-Adviser regarding such matters as the composition of assets of each Segment, cash requirements and cash available for investment in each Segment, and all other information as may be reasonably necessary for theSub-Adviser to perform its responsibilities hereunder.

b. The Manager has furnished theSub-Adviser a copy of the prospectus and statement of additional information of the Funds and agrees during the continuance of this Agreement to furnish theSub-Adviser copies of any revisions or supplements thereto at, or, if practicable, before the time the revisions or supplements become effective. The Manager agrees to furnish theSub-Adviser with minutes of meetings of the trustees of the Trust applicable to the Funds to the extent they may affect the duties of theSub-Adviser, and with copies of any financial statements or reports made by the Funds to its shareholders, and any further materials or information which theSub-Adviser may reasonably request to enable it to perform its functions under this Agreement.

3.Custodian. The Manager shall provide theSub-Adviser with a copy of the Funds’ agreement with the custodian designated to hold the assets of the Funds (the “Custodian”) and any modifications thereto (the “Custody Agreement”), copies of such modifications to be provided to theSub-Adviser a reasonable time in advance of the effectiveness of such modifications. The assets of each Segment shall be maintained in the custody of the Custodian identified in, and in accordance with the terms and conditions of, the Custody Agreement (or anysub-custodian properly appointed as provided in the Custody Agreement). TheSub-Adviser shall have no liability for the acts or omissions of the Custodian, unless such act or omission is taken solely in reliance upon instruction given to the Custodian by a representative of theSub-Adviser properly authorized to give such instruction under the Custody Agreement. Any assets added to each Fund shall be delivered directly to the Custodian.

4.Proprietary Rights. The Manager agrees and acknowledges that theSub-Adviser is the sole owner of the name “Harris Associates L.P.” and that all use of any designation consisting in whole or part of “Harris Associates L.P.” under this Agreement shall inure to the benefit of theSub-Adviser. The Manager on its own behalf and on behalf of the Funds agrees not to use any such designation in any advertisement or sales literature or other materials promoting the Funds, except with the prior written consent of theSub-Adviser. Without the prior written consent of theSub-Adviser, the Manager shall not, and the Manager shall use its best efforts to cause the Funds not to, make representations regarding theSub-Adviser in any disclosure document, advertisement or sales literature or other materials relating to any Fund. Upon termination of this Agreement for any reason with respect to any Fund, the Manager shall cease, and the Manager shall use its best efforts to cause the applicable Fund to cease, all use of any such designation as soon as reasonably practicable.

3

5.Expenses. Except for expenses specifically assumed or agreed to be paid by theSub-Adviser pursuant hereto, theSub-Adviser shall not be liable for any organizational, operational or business expenses of the Manager or the Trust including, without limitation, (a) interest and taxes, (b) brokerage commissions and other costs in connection with the purchase or sale of securities or other investment instruments with respect to the Funds, and (c) custodian fees and expenses. Any reimbursement of advisory fees required by any expense limitation provision of any law shall be the sole responsibility of the Manager. The Manager and theSub-Adviser shall not be considered as partners or participants in a joint venture. TheSub-Adviser will pay its own expenses incurred in furnishing the services to be provided by it pursuant to this Agreement. Neither theSub-Adviser nor any affiliated person thereof shall be entitled to any compensation from the Manager or the Trust with respect to service by any affiliated person of theSub-Adviser as an officer or trustee of the Trust (other than the compensation to theSub-Adviser payable by the Manager pursuant to Section 7 hereof).

6,Purchase and Sale of Assets. Absent instructions from the Manager to the contrary, theSub-Adviser shall place all orders for the purchase and sale of securities for each Segment with brokers or dealers selected by theSub-Adviser, which may include brokers or dealers affiliated with theSub-Adviser, provided such orders comply with Rule17e-1 under the 1940 Act in all respects. To the extent consistent with applicable law, purchase or sell orders for the Segments may be aggregated with contemporaneous purchase or sell orders of other clients of theSub-Adviser. TheSub-Adviser shall use its best efforts to obtain execution of transactions for the Segments at prices which are advantageous to the Funds and at commission rates that are reasonable in relation to the benefits received. However, theSub-Adviser may select brokers or dealers on the basis that they provide brokerage, research or other services or products to the Funds and/or other accounts serviced by theSub-Adviser. To the extent consistent with applicable law, theSub-Adviser may pay a broker or dealer an amount of commission for effecting a securities transaction in excess of the amount of commission or dealer spread another broker or dealer would have charged for effecting that transaction if theSub-Adviser determines in good faith that such amount of commission was reasonable in relation to the value of the brokerage and research products and/or services provided by such broker or dealer. This determination, with respect to brokerage and research services or products, may be viewed in terms of either that particular transaction or the overall responsibilities which theSub-Adviser and its affiliates have with respect to the Funds or to accounts over which they exercise investment discretion. Not all such services or products need be used by theSub-Adviser in managing the Segments.

4

To the extent permitted by applicable law, and in all instances subject to the foregoing policy of best execution, theSub-Adviser may allocate brokerage transactions to broker-dealers (including affiliates of Natixis Distribution, L.P.) that have entered into arrangements in which the broker-dealer allocates a portion of the commissions paid by a fund toward the reduction of that fund’s expenses, subject to the policy of best execution.

The Manager agrees that, subject to its fiduciary duties to the Funds arising from its position as Manager of the Funds, the Manager shall not dictate brokerage allocation or selection decisions or investment decisions to or for the Funds, either directly or pursuant to directions given to theSub-Adviser by the Manager; provided, however, that nothing in this paragraph shall prohibit officers of the Trust (who may also be officers or employees of the Manager) from exercising authority conferred upon them as officers of the Trust by the Board of Trustees of the Trust.

7.Compensation of theSub-Adviser. As full compensation for all services rendered, facilities furnished and expenses borne by theSub-Adviser hereunder, with respect to each Segment of each Fund, theSub-Adviser shall be paid at the annual rate not to exceed 0.70% of the average daily net assets of such Segment of the Fund (or such lesser amount as theSub-Adviser may from time to time agree to receive). The compensation schedule for the current Segments of the Funds is set forth in Schedule B. Additional Segments of the Funds may be added in the future, Such compensation shall be paid by the Trust (except to the extent that the Trust, theSub-Adviser and the Manager otherwise agree in writing from time to time). Such compensation shall be payable monthly in arears or at such other intervals, not less frequently than quarterly, as the Manager is paid by the Funds pursuant to the Advisory Agreement.

8.Non-Exclusivity. The Manager and the Trust on behalf of the Funds agree that the services of theSub-Adviser are not to be deemed exclusive and that theSub-Adviser and its affiliates are free to act as investment manager and provide other services to various investment companies and other managed accounts, except as theSub-Adviser and the Manager or the Administrator may otherwise agree from time to time in writing before or after the date hereof. This Agreement shall not in any way limit or restrict theSub-Adviser or any of its directors, officers, employees or agents from buying, selling or trading any securities or other investment instruments for its or their own account or for the account of others for whom it or they may be acting, provided that such activities do not adversely affect or otherwise impair the performance by theSub-Adviser of its duties and obligations under this Agreement. The Manager and the Trust recognize and agree that theSub-Adviser may provide advice to or take action with respect to other clients, which advice or action, including the timing and nature of such action, may differ from or be identical to advice given or action taken with respect to the Funds. TheSub-Adviser shall for all purposes hereof be deemed to be an independent contractor and shall, unless otherwise provided or authorized, have no authority to act for or represent the Trust or the Manager in any way or otherwise be deemed an agent of the Funds or the Manager.

5

9.Liability. Except as may otherwise be provided by the 1940 Act or other federal securities laws, neither theSub-Adviser nor any of its officers, directors, partners, employees or agents (the “Indemnified Parties”) shall be subject to any liability to the Manager, the Trust, any Fund or any shareholder of a Fund for any error of judgment, any mistake of law or any loss arising out of any investment or other act or omission in the course of, connected with, or arising out of any service to be rendered under this Agreement, except by reason of willful misfeasance, bad faith or gross negligence in the performance of theSub-Adviser’s duties or by reason of reckless disregard by theSub-Adviser of its obligations and duties hereunder. The Manager shall hold harmless and indemnify theSub-Adviser for any loss, liability, cost, damage or expense (including reasonable attorneys’ fees and costs) arising from any claim or demand by any past or present shareholder of any Fund that is not based upon the obligations of theSub-Adviser with respect to any Segment under this Agreement.

Without limiting the foregoing, it is expressly understood and agreed that the Manager and each Fund shall hold harmless and indemnify the Indemnified Parties for any loss arising out of any act or omission of any othersub-adviser to the Fund, or for any loss arising out of the failure of the Fund to comply with the Policies, except for losses arising out of theSub-Adviser’s failure to comply with the Policies with respect to a Segment.

The Manager acknowledges and agrees that theSub-Adviser makes no representation or warranty, expressed or implied, that any level of performance or investment results will be achieved by any Fund or any Segment or that any Fund or any Segment will perform comparably with any standard or index, including other clients of theSub-Adviser, whether public or private.

a. unless otherwise terminated, this Agreement shall continue in effect for two years from the date of execution, and from year to year thereafter so long as such continuance is specifically approved at least annually (i) by the Board of Trustees of the Trust or with respect to any Fund by vote of a majority of the outstanding voting securities of the Fund, and (ii) by vote of a majority of the trustees of the Trust who are not interested persons of the Trust, the Manager or theSub-Adviser, cast in person at a meeting called for the purpose of voting on such approval;

Sub-Advisory Agreement (this “Agreement”) entered into as of this 30th day of April, 2019, by and among Natixis Funds Trust IV, a Massachusetts business trust (the “Trust”), with respect to its series listed in Schedule A (each a “Fund” and, collectively, the “Funds”), Natixis Advisors, L.P., a Delaware limited partnership (the “Manager”), and Loomis, Sayles & Company, L.P., a Delaware limited partnership (the“Sub-Adviser”).

WHEREAS, the Manager has entered into an Advisory Agreement dated February 28, 2017 (the “Advisory Agreement”) with the Trust, relating to the provision of portfolio management and administrative services to the Funds;

WHEREAS, the Advisory Agreement provides that the Manager may delegate any or all of its portfolio management responsibilities under the Advisory Agreement to one or moresub-advisers;

WHEREAS, the Manager and the Trustees of the Trust desire to retain theSub- Adviser to render portfolio management services in the manner and on the terms set forth in this Agreement.

NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth in this Agreement, the Trust, the Manager and theSub-Adviser agree as follows:

1.Sub-Advisory Services.

a. TheSub-Adviser shall, subject to the supervision of the Manager and of any administrator appointed by the Manager (the “Administrator”), manage the investment and reinvestment of such portion the assets of each Fund as the Manager or its designee may from time to time allocate to theSub-Adviser for management (each a “Segment” and, collectively, the “Segments”). TheSub- Adviser shall have the authority on behalf of each Fund to vote and shall vote all proxies and exercise all other rights of the Funds as a security holder of companies in which the Segments from time to time invest. TheSub-Adviser shall manage each Segment in conformity with (1) the investment objective, policies and restrictions of the applicable Segment of the applicable Fund set forth in the Trust’s prospectus and statement of additional information relating to the Fund, (2) any additional policies or guidelines established by the Manager or by the Trust’s trustees that have been furnished in writing to theSub-Adviser

1

and (3) the provisions of the Internal Revenue Code as amended (the “Code”) applicable to “regulated investment companies” (as defined in Section 851 of the Code), all as from time to time in effect (collectively, the “Policies”), and with all applicable provisions of law, including without limitation all applicable provisions of the Investment Company Act of 1940, as amended (the “1940 Act”) and the rules and regulations thereunder. For purposes of compliance with the Policies, theSub-Adviser shall be entitled to treat each Segment as though the Segment constituted the entire Fund, and theSub-Adviser shall not be responsible in any way for the compliance of any assets of the Funds, other than the Segments, with the Policies, or for the compliance of the Funds, taken as a whole, with the Policies. For clarification, theSub-Adviser is not responsible for the requirements of the Code or the 1940 Act that Natixis Advisors believes should be monitored for at the Fund level (for example, concentration, diversification and liquidity limits). Subject to the foregoing, theSub-Adviser is authorized, in its discretion and without prior consultation with the Manager, to buy, sell, lend and otherwise trade in any stocks, bonds and other securities and investment instruments on behalf of the Funds, without regard to the length of time the securities have been held and the resulting rate of portfolio turnover or any tax considerations; and the majority or the whole of each Fund may be invested in such proportions of stocks, bonds, other securities or investment instruments, or cash, as theSub-Adviser shall determine. Notwithstanding the foregoing provisions of this Section 1 however, theSub-Adviser shall, upon written instructions from the Manager, effect such portfolio transactions for a Segment as the Manager shall determine are necessary in order for the applicable Fund to comply with the Policies.

b. TheSub-Adviser shall furnish the Manager and the Administrator monthly, quarterly and annual reports concerning portfolio transactions and performance of the Segments in such form as may be mutually agreed upon, and agrees to review the Segments and discuss the management of the Segments with the Manager and the Administrator. TheSub-Adviser shall permit all books and records with respect to the Segments to be inspected and audited by the Manager and the Administrator at all reasonable times during normal business hours, upon reasonable notice. TheSub-Adviser shall also provide the Manager with such other information and reports as may reasonably be requested by the Manager from time to time, including without limitation all material requested by or required to be delivered to the Trustees of the Trust.

c. TheSub-Adviser shall provide to the Manager a copy of theSub- Adviser’s Form ADV as filed with the Securities and Exchange Commission and a list of the persons whom theSub-Adviser wishes to have authorized to give written and/or oral instructions to custodians of assets of the Funds.

2

2.Obligations of the Manager.

a. The Manager shall provide (or cause the Funds’ Custodian (as defined in Section 3 hereof) to provide) timely information to theSub-Adviser regarding such matters as the composition of assets of each Segment, cash requirements and cash available for investment in each Segment, and all other information as may be reasonably necessary for theSub-Adviser to perform its responsibilities hereunder.

b. The Manager has furnished theSub-Adviser a copy of the prospectus and statement of additional information of the Funds and agrees during the continuance of this Agreement to furnish theSub-Adviser copies of any revisions or supplements thereto at, or, if practicable, before the time the revisions or supplements become effective. The Manager agrees to furnish theSub-Adviser with minutes of meetings of the trustees of the Trust applicable to the Funds to the extent they may affect the duties of theSub-Adviser, and with copies of any financial statements or reports made by the Funds to its shareholders, and any further materials or information which theSub-Adviser may reasonably request to enable it to perform its functions under this Agreement.

3.Custodian. The Manager shall provide theSub-Adviser with a copy of the Funds’ agreement with the custodian designated to hold the assets of the Funds (the “Custodian”) and any modifications thereto (the “Custody Agreement”), copies of such modifications to be provided to theSub-Adviser a reasonable time in advance of the effectiveness of such modifications. The assets of each Segment shall be maintained in the custody of the Custodian identified in, and in accordance with the terms and conditions of, the Custody Agreement (or anysub-custodian properly appointed as provided in the Custody Agreement). TheSub-Adviser shall have no liability for the acts or omissions of the Custodian, unless such act or omission is taken solely in reliance upon instruction given to the Custodian by a representative of theSub-Adviser properly authorized to give such instruction under the Custody Agreement. Any assets added to each Fund shall be delivered directly to the Custodian.

4.Proprietary Rights. The Manager agrees and acknowledges that theSub-Adviser is the sole owner of the name “Loomis, Sayles & Company, L.P.” and that all use of any designation consisting in whole or part of “Loomis, Sayles & Company, L.P. under this Agreement shall inure to the benefit of theSub-Adviser. The Manager on its own behalf and on behalf of the Funds agrees not to use any such designation in any advertisement or sales literature or other materials promoting the Funds, except with the prior written consent of theSub-Adviser. Without the prior written consent of theSub-Adviser, the Manager shall not, and the Manager shall use its best efforts to cause the Funds not to, make representations regarding theSub-Adviser in any disclosure

3

document, advertisement or sales literature or other materials relating to any Fund. Upon termination of this Agreement for any reason with respect to any Fund, the Manager shall cease, and the Manager shall use its best efforts to cause the applicable Fund to cease, all use of any such designation as soon as reasonably practicable.

5.Expenses. Except for expenses specifically assumed or agreed to be paid by theSub- Adviser pursuant hereto, theSub-Adviser shall not be liable for any organizational, operational or business expenses of the Manager or the Trust including, without limitation, (a) interest and taxes, (b) brokerage commissions and other costs in connection with the purchase or sale of securities or other investment instruments with respect to the Funds, and (c) custodian fees and expenses. Any reimbursement of advisory fees required by any expense limitation provision of any law shall be the sole responsibility of the Manager. The Manager and theSub-Adviser shall not be considered as partners or participants in a joint venture. TheSub-Adviser will pay its own expenses incurred in furnishing the services to be provided by it pursuant to this Agreement. Neither theSub-Adviser nor any affiliated person thereof shall be entitled to any compensation from the Manager or the Trust with respect to service by any affiliated person of theSub-Adviser as an officer or trustee of the Trust (other than the compensation to theSub-Adviser payable by the Manager pursuant to Section 7 hereof).

6.Purchase and Sale of Assets. Absent instructions from the Manager to the contrary, theSub-Adviser shall place all orders for the purchase and sale of securities for each Segment with brokers or dealers selected by theSub-Adviser, which may include brokers or dealers affiliated with theSub-Adviser, provided such orders comply with Rule17e-1 under the 1940 Act in all respects. To the extent consistent with applicable law, purchase or sell orders for the Segments may be aggregated with contemporaneous purchase or sell orders of other clients of theSub-Adviser. TheSub-Adviser shall use its best efforts to obtain execution of transactions for the Segments at prices which are advantageous to the Funds and at commission rates that are reasonable in relation to the benefits received. However, theSub-Adviser may select brokers or dealers on the basis that they provide brokerage, research or other services or products to the Funds and/or other accounts serviced by theSub-Adviser. To the extent consistent with applicable law, theSub-Adviser may pay a broker or dealer an amount of commission for effecting a securities transaction in excess of the amount of commission or dealer spread another broker or dealer would have charged for effecting that transaction if theSub-Adviser determines in good faith that such amount of commission was reasonable in relation to the value of the brokerage and research products and/or services provided by such broker or dealer. This determination, with respect to brokerage and research services or products, may be viewed in terms of either that particular transaction or the overall responsibilities which theSub-Adviser and its affiliates have with respect to the Funds or to accounts over which they exercise investment discretion. Not all such services or products need be used by theSub-Adviser in managing the Segments.

4

To the extent permitted by applicable law, and in all instances subject to the foregoing policy of best execution, theSub-Adviser may allocate brokerage transactions to broker-dealers (including affiliates of Natixis Distribution, L.P.) that have entered into arrangements in which the broker-dealer allocates a portion of the commissions paid by a fund toward the reduction of that fund’s expenses, subject to the policy of best execution.

The Manager agrees that, subject to its fiduciary duties to the Funds arising from its position as Manager of the Funds, the Manager shall not dictate brokerage allocation or selection decisions or investment decisions to or for the Funds, either directly or pursuant to directions given to theSub-Adviser by the Manager; provided, however, that nothing in this paragraph shall prohibit officers of the Trust (who may also be officers or employees of the Manager) from exercising authority conferred upon them as officers of the Trust by the Board of Trustees of the Trust.

7.Compensation of theSub-Adviser. As full compensation for all services rendered, facilities furnished and expenses borne by theSub-Adviser hereunder, with respect to each Segment of each Fund, theSub-Adviser shall be paid at the annual rate not to exceed 0.70% of the average daily net assets of such Segment of the Fund (or such lesser amount as theSub-Adviser may from time to time agree to receive). The compensation schedule for the current Segments of the Funds is set forth in Schedule B. Additional Segments of the Funds may be added in the future. Such compensation shall be paid by the Trust (except to the extent that the Trust, theSub-Adviser and the Manager otherwise agree in writing from time to time). Such compensation shall be payable monthly in arears or at such other intervals, not less frequently than quarterly, as the Manager is paid by the Funds pursuant to the Advisory Agreement.

8.Non-Exclusivity. The Manager and the Trust on behalf of the Funds agree that the services of theSub-Adviser are not to be deemed exclusive and that theSub-Adviser and its affiliates are free to act as investment manager and provide other services to various investment companies and other managed accounts, except as theSub-Adviser and the Manager or the Administrator may otherwise agree from time to time in writing before or after the date hereof. This Agreement shall not in any way limit or restrict theSub-Adviser or any of its directors, officers, employees or agents from buying, selling or trading any securities or other investment instruments for its or their own account or for the account of others for whom it or they may be acting, provided that such activities do not adversely affect or otherwise impair the performance by theSub-Adviser of its duties and obligations under this Agreement. The Manager and the Trust recognize and agree that theSub-Adviser may provide advice to or take action with respect to other clients, which advice or action, including the timing and nature of such action, may differ from or be identical to advice given or action taken with respect to the Funds. TheSub-Adviser shall for all purposes hereof be deemed to be an independent contractor and shall, unless otherwise provided or authorized, have no authority to act for or represent the Trust or the Manager in any way or otherwise be deemed an agent of the Funds or the Manager.

5

9.Liability. Except as may otherwise be provided by the 1940 Act or other federal securities laws, neither theSub-Adviser nor any of its officers, directors, partners, employees or agents (the “Indemnified Parties”) shall be subject to any liability to the Manager, the Trust, any Fund or any shareholder of a Fund for any error of judgment, any mistake of law or any loss arising out of any investment or other act or omission in the course of, connected with, or arising out of any service to be rendered under this Agreement, except by reason of willful misfeasance, bad faith or gross negligence in the performance of theSub-Adviser’s duties or by reason of reckless disregard by theSub-Adviser of its obligations and duties hereunder. The Manager shall hold harmless and indemnify theSub-Adviser for any loss, liability, cost, damage or expense (including reasonable attorneys’ fees and costs) arising from any claim or demand by any past or present shareholder of any Fund that is not based upon the obligations of theSub-Adviser with respect to any Segment under this Agreement.

Without limiting the foregoing, it is expressly understood and agreed that the Manager and each Fund shall hold harmless and indemnify the Indemnified Parties for any loss arising out of any act or omission of any othersub-adviser to the Fund, or for any loss arising out of the failure of the Fund to comply with the Policies, except for losses arising out of theSub-Adviser’s failure to comply with the Policies with respect to a Segment.

The Manager acknowledges and agrees that theSub-Adviser makes no representation or warranty, expressed or implied, that any level of performance or investment results will be achieved by any Fund or any Segment or that any Fund or any Segment will perform comparably with any standard or index, including other clients of theSub-Adviser, whether public or private.

10.Effective Date and Termination. This Agreement shall become effective as of the date of its execution, and

a. unless otherwise terminated, this Agreement shall continue in effect for two years from the date of execution, and from year to year thereafter so long as such continuance is specifically approved at least annually (i) by the Board of Trustees of the Trust or with respect to any Fund by vote of a majority of the outstanding voting securities of the Fund, and (ii) by vote of a majority of the trustees of the Trust who are not interested persons of the Trust, the Manager or theSub-Adviser, cast in person at a meeting called for the purpose of voting on such approval;
