Notes to Financial Statements

June 30, 2026 (Unaudited)

1.Organization. Gateway Trust and Natixis Funds Trust I (the “Trusts” and each a “Trust”) are each organized as a Massachusetts business trust. Each Trust is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. Each Declaration of Trust permits the Board of Trustees to authorize the issuance of an unlimited number of shares of the Trust in multiple series. The financial statements for certain funds of the Trusts are presented in separate reports. The following funds (individually, a “Fund” and collectively, the “Funds”) are included in this report:

Gateway Trust:

Gateway Fund
Gateway Equity Call Premium Fund

Natixis Funds Trust I:

Mirova Global Megatrends Fund (“Global Megatrends Fund”)

Each Fund is a diversified investment company.

Each Fund offers Class A, Class C, Class N and Class Y shares.

Class A shares are sold with a maximum front-end sales charge of 5.75%. Class C shares do not pay a front-end sales charge, pay higher Rule 12b-1 fees than Class A shares for eight years (at which point they automatically convert to Class A shares) (prior to May 1, 2021, Class C shares automatically converted to Class A shares after ten years) and may be subject to a contingent deferred sales charge (“CDSC”) of 1.00% if those shares are redeemed within one year of acquisition, except for reinvested distributions. Class N and Class Y shares do not pay a front-end sales charge, a CDSC or Rule 12b-1 fees. Class N shares are offered with an initial minimum investment of $1,000,000. Class Y shares are offered with an initial minimum investment of $100,000. Certain categories of investors are exempted from the minimum investment amounts for Class N and Class Y as outlined in the relevant Funds’ prospectus.

Most expenses can be directly attributed to a Fund. Expenses which cannot be directly attributed to a Fund are generally apportioned based on the relative net assets of each of the Funds in Natixis Funds Trust I, Natixis Funds Trust II, Natixis Funds Trust IV and Gateway Trust (“Natixis Funds Trusts”), Loomis Sayles Funds I and Loomis Sayles Funds II, Loomis Sayles Credit Income Opportunities Fund (collectively, the “Loomis Sayles Funds Trusts”) and Natixis ETF Trust and Natixis ETF Trust II (“Natixis ETF Trusts”). Expenses of a Fund are borne pro rata by the holders of each class of shares, except that each class bears expenses unique to that class (such as the Rule 12b-1 fees applicable to Class A and Class C), and transfer agent fees are borne collectively for Class A, Class C and Class Y, and individually for Class N. In addition, each class votes as a class only with respect to its own Rule 12b-1 Plan. Shares of each class would receive their pro rata share of the net assets of the Fund if the Fund were liquidated. The Trustees approve separate distributions from net investment income on each class of shares.

2.Significant Accounting Policies. The following is a summary of significant accounting policies consistently followed by each Fund in the preparation of its financial statements. The Funds' financial statements follow the accounting and reporting guidelines provided for investment companies and are prepared in accordance with accounting principles generally accepted in the United States of America which require the use of management estimates that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. Each Fund operates as a single segment entity, focusing on investments in a portfolio of securities. Each Fund's named president acts as chief operating decision maker ("CODM") regarding allocation of resources and performance assessment. Financial information including, but not limited to, portfolio composition, net asset changes and total returns, is used by the CODM to assess performance and to make resource allocation decisions and is consistent with that presented within the financial statements. Management has evaluated the events and transactions subsequent to period-end through the date the financial statements were issued and has determined that there were no material events that would require disclosure in the Funds' financial statements.

a. Valuation. Registered investment companies are required to value portfolio investments using an unadjusted, readily available market quotation. Each Fund obtains readily available market quotations from independent pricing services. Fund investments for which readily available market quotations are not available are priced at fair value pursuant to the Funds’ Valuation Procedures. The Board of Trustees has approved a valuation designee who is subject to the Board’s oversight.

Unadjusted readily available market quotations that are utilized for exchange traded equity securities (including shares of closed-end investment companies and exchange-traded funds) include the last sale price quoted on the exchange where the security is traded most extensively. Domestic, exchange-traded index and single name equity option contracts (including options on exchange-traded funds) are valued at the mean of the National Best Bid and Offer quotations as determined by the Options Price Reporting Authority. Shares of open-end investment companies are valued at net asset value (“NAV”) per share.

Exchange traded equity securities for which there is no reported sale during the day are fair valued at the closing bid quotation as reported by an independent pricing service. Unlisted equity securities (except unlisted preferred equity securities) are fair valued at the last sale price quoted in the market where they are traded most extensively or, if there is no reported sale during the day, the closing bid quotation as reported by an independent pricing service. If there is no last sale price or closing bid quotation available, unlisted equity securities will be fair valued using evaluated bids furnished by an independent pricing service, if available.

27 |

Notes to Financial Statements (continued)

June 30, 2026 (Unaudited)

Debt securities and unlisted preferred equity securities are fair valued based on evaluated bids furnished to the Funds by an independent pricing service or bid prices obtained from broker-dealers. Broker-dealer bid prices may be used to fair value debt and unlisted equities where an independent pricing service is unable to price an investment or where an independent pricing service does not provide a reliable price for the investment.

The Funds may also fair value investments in other circumstances such as when extraordinary events occur after the close of a foreign market, but prior to the close of the New York Stock Exchange. This may include situations relating to a single issuer (such as a declaration of bankruptcy or a delisting of the issuer’s security from the primary market on which it has traded) as well as events affecting the securities markets in general (such as market disruptions or closings and significant fluctuations in U.S. and/or foreign markets). When fair valuing a Fund’s investments, the valuation designee may, among other things, use modeling tools or other processes that may take into account factors such as issuer specific information, or other related market activity and/or information that occurred after the close of the foreign market but before the time the Fund’s NAV is calculated. Fair valuation by the Fund(s) valuation designee may require subjective determinations about the value of the investment, and fair values used to determine a Fund’s NAV may differ from quoted or published prices, or from prices that are used by others, for the same investments. In addition, the use of fair value pricing may not always result in adjustments to the prices of investments held by a Fund.

b. Investment Transactions and Related Investment Income. Investment transactions are accounted for on a trade date plus one day basis for daily NAV calculation. However, for financial reporting purposes, investment transactions are reported on trade date. Dividend income (including income reinvested) and foreign withholding tax, if applicable, are recorded on the ex-dividend date, or in the case of certain foreign securities, as soon as a Fund is notified, and interest income is recorded on an accrual basis. Dividends reinvested and stock dividends are reflected as non-cash dividends on the Statements of Operations. Interest income is increased by the accretion of discount and decreased by the amortization of premium, if applicable. For securities with paydown provisions, principal payments received are treated as a proportionate reduction to the cost basis of the securities, and excess or shortfall amounts are recorded as income. Distributions received from investments in securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments or as a realized gain, respectively. The calendar year-end amounts of ordinary income, capital gains, and return of capital included in distributions received from the Funds’ investments in real estate investment trusts (“REITs”) are reported to the Funds after the end of the fiscal year; accordingly, the Funds estimate these amounts for accounting purposes until the characterization of REIT distributions is reported to the Funds after the end of the fiscal year. Estimates are based on the most recent REIT distribution information available. In determining net gain or loss on securities sold, the cost of securities has been determined on an identified cost basis. Investment income, non-class specific expenses and realized and unrealized gains and losses are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of the Fund.

c. Foreign Currency Translation. The books and records of the Funds are maintained in U.S. dollars. The values of securities, currencies and other assets and liabilities denominated in currencies other than U.S. dollars, if any, are translated into U.S. dollars based upon foreign exchange rates prevailing at the end of the period. Purchases and sales of investment securities, income and expenses are translated into U.S. dollars on the respective dates of such transactions.

Net realized foreign exchange gains or losses arise from sales of foreign currency, changes in exchange rates between the trade and settlement dates on securities transactions and the difference between the amounts of dividends, interest and foreign withholding taxes recorded in the Funds’ books and records and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains or losses arise from changes in the value of assets and liabilities, other than investment securities, as of the end of the fiscal period, resulting from changes in exchange rates. Net realized foreign exchange gains or losses and the net change in unrealized foreign exchange gains or losses are disclosed in the Statements of Operations. For federal income tax purposes, net realized foreign exchange gains or losses are characterized as ordinary income and may, if the Funds have net losses, reduce the amount of income available to be distributed by the Funds.

The values of investment securities are presented at the foreign exchange rates prevailing at the end of the period for financial reporting purposes. Net realized and unrealized gains or losses on investments reported in the Statements of Operations reflect gains or losses resulting from changes in exchange rates and fluctuations which arise due to changes in market prices of investment securities. For federal income tax purposes, a portion of the net realized gain or loss on investments arising from changes in exchange rates, which is reflected in the Statements of Operations, may be characterized as ordinary income and may, if the Funds have net losses, reduce the amount of income available to be distributed by the Funds.

The Funds may use foreign currency exchange contracts to facilitate transactions in foreign-denominated investments. Losses may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts’ terms.

d. Option Contracts. Gateway Fund and Gateway Equity Call Premium Fund’s investment strategies make use of exchange-traded options. Exchange-traded options are standardized contracts and are settled through a clearing house with fulfillment supported by the credit of the exchange. Therefore, counterparty credit risks to a Fund are reduced.

When a Fund writes an index call option, an amount equal to the net premium received (the premium less commission) is recorded as a liability and is subsequently adjusted to the current value until the option expires or a Fund enters into a closing purchase transaction.

| 28

Notes to Financial Statements (continued)

June 30, 2026 (Unaudited)

When an index call option expires or a Fund enters into a closing purchase transaction, the difference between the net premium received and any amount paid at expiration or on effecting a closing purchase transaction, including commission, is treated as a realized gain or, if the net premium received is less than the amount paid, as a realized loss. A Fund, as writer of an index call option, bears the risk of an unfavorable change in the market value of the index underlying the written option.

When a Fund purchases an index put option, it pays a premium and the index put option is subsequently marked-to-market to reflect current value until the option expires or a Fund enters into a closing sale transaction. Premiums paid for purchasing index put options which expire are treated as realized losses. When a Fund enters into a closing sale transaction, the difference between the premium paid and the proceeds of the closing sale transaction is treated as a realized gain or loss. The risk associated with purchasing index put options is limited to the premium paid. Option contracts outstanding at the end of the period, if any, are listed in each applicable Fund’s Portfolio of Investments.

e. Federal and Foreign Income Taxes. The Trusts treat each Fund as a separate entity for federal income tax purposes. Each Fund intends to meet the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. Management has performed an analysis of each Fund’s tax positions for the open tax years as of June 30, 2026 and has concluded that no provisions for income tax are required. The Funds’ federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

A Fund may be subject to foreign withholding taxes on investment income and taxes on capital gains on investments that are accrued and paid based upon the Fund’s understanding of the tax rules and regulations that exist in the countries in which the Fund invests. Foreign withholding taxes on dividend and interest income are reflected on the Statements of Operations as a reduction of investment income, net of amounts that have been or are expected to be reclaimed and paid. Dividends and interest receivable on the Statements of Assets and Liabilities are net of foreign withholding taxes. Foreign withholding taxes where reclaims have been or are expected to be filed and paid are reflected on the Statements of Assets and Liabilities as tax reclaims receivable. Capital gains taxes paid are included in net realized gain (loss) on investments in the Statements of Operations. Accrued but unpaid capital gains taxes are reflected as foreign taxes payable on the Statements of Assets and Liabilities, if applicable, and reduce unrealized gains on investments. In the event that realized gains on investments are subsequently offset by realized losses, taxes paid on realized gains may be returned to a Fund. Such amounts, if applicable, are reflected as foreign tax rebates receivable on the Statements of Assets and Liabilities and are recorded as a realized gain when received.

Certain Funds have filed tax reclaims for previously withheld taxes on dividends earned in certain European Union countries (“EU reclaims”) and may continue to make such filings when it is determined to be in the best interest of the Funds and their shareholders. These filings are subject to various administrative proceedings by the local jurisdictions’ tax authorities within the European Union, as well as a number of related judicial proceedings. EU reclaims are recognized by a Fund when deemed more likely than not to be collected, and are reflected as tax reclaims in the Statements of Operations. Any related receivable is reflected as tax reclaims receivable in the Statements of Assets and Liabilities. Under certain circumstances, and to the extent that EU reclaims recovered by a Fund were previously passed-through as foreign tax credits to its U.S. taxable shareholders, a Fund may enter into closing agreements with the Internal Revenue Service ("IRS"). Doing so will enable a Fund to quantify and remit its tax liability related to any recoveries (on behalf of its shareholders). Accordingly, estimated charges, if any, related to a Fund’s closing agreement liability are presented as tax reclaim expenses in the Statements of Operations and its estimated closing agreement liability is presented as tax reclaim payable in the Statements of Assets and Liabilities. The actual closing agreement payment to the IRS may differ from the estimate and that difference may be material.

f. Dividends and Distributions to Shareholders. Dividends and distributions are recorded on the ex-dividend date. The timing and characterization of certain income and capital gain distributions are determined in accordance with federal tax regulations, which may differ from accounting principles generally accepted in the United States of America. Permanent differences are primarily due to differing treatments for book and tax purposes of items such as redemptions in-kind, passive foreign investment company adjustments, capital gain distribution received, return of capital distributions received, corporate actions, distributions in excess of income and/or capital gain and foreign currency gains and losses. Permanent book and tax basis differences relating to shareholder distributions, net investment income and net realized gains will result in reclassifications to capital accounts reported on the Statements of Assets and Liabilities. Temporary differences between book and tax distributable earnings are primarily due to wash sales, deferred Trustees’ fees, passive foreign investment company adjustments, capital gain distribution received, corporate actions, options contract mark-to-market, deferral of EU reclaim and return of capital distributions received. Amounts of income and capital gain available to be distributed on a tax basis are determined annually, and at other times during the Funds’ fiscal year as may be necessary to avoid knowingly declaring and paying a return of capital distribution. Distributions from net investment income and short-term capital gains are considered to be distributed from ordinary income for tax purposes.

29 |

Notes to Financial Statements (continued)

June 30, 2026 (Unaudited)

The tax characterization of distributions is determined on an annual basis. The tax character of distributions paid to shareholders during the year ended December 31, 2025 was as follows:

	2025 Distributions
Fund	Ordinary Income	Long-Term Capital Gains	Total
Gateway Fund	$35,333,923	$ —	$35,333,923
Gateway Equity Call Premium Fund	1,684,130	—	1,684,130
Global Megatrends Fund	3,123,117	36,398,816	39,521,933

Distributions paid to shareholders from net investment income and net realized capital gains, based on accounting principles generally accepted in the United States of America, are consolidated and reported on the Statements of Changes in Net Assets as Distributions to Shareholders. Distributions paid to shareholders from net investment income and net realized capital gains expressed in per-share amounts, based on accounting principles generally accepted in the United States of America, are separately stated and reported within the Financial Highlights.

As of December 31, 2025, capital loss carryforwards and late-year ordinary and post-October capital loss deferrals were as follows:

	Gateway Fund	Gateway Equity Call Premium Fund	Global Megatrends Fund
Capital loss carryforward:
Short-term:
No expiration date	$(859,986,661 )	$(20,789,531 )	$ —
Long-term:
No expiration date	—	(4,568,795 )	—
Total capital loss carryforward	$(859,986,661 )	$(25,358,326 )	$—
Late-year ordinary and post-October capital loss deferrals*	$—	$—	$(85,860 )

Under current tax law, capital losses, foreign currency losses, and losses on passive foreign investment companies and contingent payment debt instruments after

October 31 or December 31, as applicable, may be deferred and treated as occurring on the first day of the following taxable year. Global Megatrends Fund is

deferring foreign currency losses.

As of June 30, 2026, the tax cost of investments (including derivatives, if applicable) and unrealized appreciation (depreciation) on a federal tax basis were as follows:

	Gateway Fund	Gateway Equity Call Premium Fund	Global Megatrends Fund
Federal tax cost	$1,476,551,736	$157,671,138	$464,687,719
Gross tax appreciation	$5,998,063,732	$184,830,014	$212,689,986
Gross tax depreciation	(71,659,443 )	(2,299,536 )	(26,293,316 )
Net tax appreciation	$5,926,404,289	$182,530,478	$186,396,670

Amounts in the table above exclude certain adjustments that will be made at the end of the Fund’s fiscal year for tax purposes. Adjustments may include, but are not limited to, wash sales and derivatives mark-to-market.

g. Repurchase Agreements. Each Fund may enter into repurchase agreements, under the terms of a Master Repurchase Agreement, under which each Fund acquires securities as collateral and agrees to resell the securities at an agreed upon time and at an agreed upon price. It is each Fund’s policy that the market value of the collateral for repurchase agreements be at least equal to 102% of the repurchase price, including interest. Certain repurchase agreements are tri-party arrangements whereby the collateral is held in a segregated account for the benefit of the Fund and on behalf of the counterparty. Repurchase agreements could involve certain risks in the event of default or insolvency of the counterparty, including possible delays or restrictions upon a Fund’s ability to dispose of the underlying securities. As of June 30, 2026, each Fund, as applicable, had investments in repurchase agreements for which the value of the related collateral exceeded the value of the repurchase agreement. The gross value of repurchase agreements is included in the Statements of Assets and Liabilities for financial reporting purposes.

h. Indemnifications. Under the Trusts’ organizational documents, their officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts

| 30

Notes to Financial Statements (continued)

June 30, 2026 (Unaudited)

with service providers that contain general indemnification clauses. The Funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, based on experience, the Funds expect the risk of loss to be remote.

3.Fair Value Measurements. In accordance with accounting standards related to fair value measurements and disclosures, the Funds have categorized the inputs utilized in determining the value of each Fund’s assets or liabilities. These inputs are summarized in the three broad levels listed below:

• Level 1 — quoted prices in active markets for identical assets or liabilities;

• Level 2 — prices determined using other significant inputs that are observable either directly, or indirectly through corroboration with observable market data (which could include quoted prices for similar assets or liabilities, interest rates, credit risk, etc.); and

• Level 3 — prices determined using significant unobservable inputs when quoted prices or observable inputs are unavailable such as when there is little or no market activity for an asset or liability (unobservable inputs reflect each Fund’s own assumptions in determining the fair value of assets or liabilities and would be based on the best information available).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The Funds' pricing policies have been approved by the Board of Trustees. Investments for which market quotations are readily available are categorized in Level 1. Other investments for which an independent pricing service is utilized are categorized in Level 2. Broker-dealer bid prices for which the Funds have knowledge of the inputs used by the broker-dealer are categorized in Level 2. All other investments, including broker-dealer bid prices for which the Funds do not have knowledge of the inputs used by the broker-dealer, as well as investments fair valued by the valuation designee, are categorized in Level 3. All Level 2 and 3 securities are defined as being fair valued.

Under certain conditions and based upon specific facts and circumstances, the Fund’s valuation designee may determine that a fair valuation should be made for portfolio investment(s). These valuation designee fair valuations will be based upon a significant amount of Level 3 inputs.

The following is a summary of the inputs used to value the Funds' investments as of June 30, 2026, at value:

Gateway Fund
Asset Valuation Inputs
Description	Level 1	Level 2	Level 3	Total
Common Stocks(a)	$7,199,566,085	$ —	$ —	$7,199,566,085

4.Derivatives. Derivative instruments are defined as financial instruments whose value and performance are based on the value and performance of an underlying asset, reference rate or index. Derivative instruments the Funds used during the period include written index call options and purchased index put options.

Through the use of index options, Gateway Fund and Gateway Equity Call Premium Fund intends that its risk management strategy will reduce the volatility inherent in equity investments while also allowing for more participation in equity returns than hybrid investments. Each Fund seeks to provide an efficient trade-off between risk and reward, where risk is characterized by volatility or fluctuations in value over time. To meet this objective, the Funds invest in a broadly diversified portfolio of common stocks, while also writing index call options and, for Gateway Fund, purchasing index put options. Writing index call options can reduce a Fund's volatility, provide a steady cash flow and be an important source of a Fund's return, although it also may reduce a Fund's ability to profit from increases in the value of its equity portfolio. Buying index put options, can protect a Fund from a significant market decline that may occur over a short period of time. The value of an index put option generally increases as the prices of stocks constituting the index decrease and decreases as those stocks increase in price. For Gateway Fund, the combination of the diversified stock portfolio, the steady cash flow from writing of index call options and the downside protection from purchased index put options is intended to provide the Fund with the majority of the returns associated with equity market investments while exposing investors to less risk than other equity investments. For Gateway Equity Call Premium Fund, the combination of the diversified stock portfolio and the steady cash flow from writing of index call options is intended to moderate the volatility of returns relative to an all-equity portfolio. During the six months ended June 30, 2026, Gateway Fund used written index call options and purchased index put options and Gateway Equity Call Premium Fund used written index call options in accordance with these strategies.

Counterparty risk is managed based on policies and procedures established by the Fund’s adviser. Such policies and procedures may include, but are not limited to, minimum counterparty credit rating requirements, monitoring of counterparty credit default swap spreads and posting of collateral. With exchange-traded derivatives, there is minimal counterparty credit risk to the Fund because the exchange’s clearing house, as counterparty to these instruments, stands between the buyer and the seller of the contract. Credit risk still exists in exchange-traded derivatives with respect to initial and variation margin that is held in a broker’s customer accounts. While brokers typically are required to segregate customer margin for exchange-traded derivatives from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its customers, U.S. bankruptcy laws will typically allocate that shortfall on a pro rata basis across all of the broker’s customers, potentially resulting in losses to the Fund.

b. Service and Distribution Fees. Natixis Distribution, LLC (“Natixis Distribution"), which is a wholly-owned subsidiary of Natixis Investment Managers, LLC, has entered into a distribution agreement with the Trusts. Pursuant to this agreement, Natixis Distribution serves as principal underwriter of the Funds of the Trusts.

Pursuant to Rule 12b-1 under the 1940 Act, the Trusts have adopted a Service Plan relating to each Fund’s Class A shares (the “Class A Plans”), a Distribution and Service Plan relating to each Fund’s Class C shares (the “Class C Plans”).

Under the Class A Plans, each Fund pays Natixis Distribution a monthly service fee at an annual rate not to exceed 0.25% of the average daily net assets attributable to the Funds’ Class A shares, as reimbursement for expenses incurred by Natixis Distribution in providing personal services to investors in Class A shares and/or the maintenance of shareholder accounts.

Under the Class C Plans, each Fund pays Natixis Distribution a monthly service fee at an annual rate not to exceed 0.25% of the average daily net assets attributable to the Funds’ Class C shares, as compensation for services provided by Natixis Distribution in providing personal services to investors in Class C shares and/or the maintenance of shareholder accounts.

d. Sub-Transfer Agent Fees. Natixis Distribution has entered into agreements, which include servicing agreements, with financial intermediaries that provide recordkeeping, processing, shareholder communications and other services to customers of the intermediaries that hold positions in the Funds and has agreed to compensate the intermediaries for providing those services. Intermediaries transact with the Funds primarily through the use of omnibus accounts on behalf of their customers who hold positions in the Funds. These services would have been provided by the Funds’ transfer agent and other service providers if the shareholders’ accounts were maintained directly at the Funds’ transfer agent. Accordingly, the Funds have agreed to reimburse Natixis Distribution for all or a portion of the servicing fees paid to these intermediaries. The reimbursement amounts (sub-transfer agent fees) paid to Natixis Distribution are subject to a sub-transfer agent fee limit approved by the Funds’ Board of Trustees, which is based on fees for similar services paid to the Funds’ transfer agent and other service providers. Class N shares do not bear such expenses.

June 30, 2026 (Unaudited)

Natixis ETF Trusts based on a formula that takes into account, among other factors, the relative net assets of each fund. Trustees are reimbursed for travel expenses in connection with attendance at meetings.

A deferred compensation plan (the “Plan”) is available to the Trustees on a voluntary basis. The value of a participating Trustee’s deferral account is based on theoretical investments of deferred amounts, on the normal payment dates, in certain funds of the Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trusts as designated by the participating Trustees. Changes in the value of participants’ deferral accounts are allocated pro rata among the funds in the Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trusts and are normally reflected as Trustees’ fees and expenses in the Statements of Operations. Deferred amounts remain in the funds until distributed in accordance with the provisions of the Plan. The portions of the accrued obligations allocated to the Funds under the Plan are reflected as Deferred Trustees’ fees in the Statements of Assets and Liabilities.

Certain officers and employees of Natixis Advisors and affiliates are also officers and/or Trustees of the Trusts.

g. Reimbursement of Transfer Agent Fees and Expenses. Natixis Advisors has given a binding contractual undertaking to Gateway Equity Call Premium Fund and Global Megatrends Fund to reimburse any and all transfer agency expenses for the Funds’ Class N shares. This undertaking is in effect through April 30, 2027, and is not subject to recovery under the expense limitation agreement described above.

For the six months ended June 30, 2026, Natixis Advisors reimbursed the Funds for transfer agency expenses as follows:

	Reimbursement of Transfer Agency Expenses
Fund	Class N
Gateway Equity Call Premium Fund	$773
Global Megatrends Fund	1,369

7.Class-Specific Transfer Agent Fees and Expenses. Transfer agent fees and expenses attributable to Class A, Class C and Class Y are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of those classes. Transfer agent fees and expenses attributable to Class N are allocated to Class N.

For the six months ended June 30, 2026, the Funds incurred the following class-specific transfer agent fees and expenses (net of expense offsets and including sub-transfer agent fees, where applicable):

	Transfer Agent Fees and Expenses
Fund	Class A	Class C	Class N	Class Y
Gateway Fund	$238,756	$13,513	$4,915	$2,151,300
Gateway Equity Call Premium Fund	1,230	234	773	112,108
Global Megatrends Fund	19,463	3,348	1,369	326,230

8.Expense Offset Arrangements. The Funds have entered into an agreement with the transfer agent whereby certain transfer agent fees and expenses may be paid indirectly by credits earned on the Funds' cash balances. Transfer agent fees and expenses are presented in the Statements of Operations gross of such credits, and the credits are presented as offsets to expenses.

9. Line of Credit. Each Fund, together with certain other funds of Natixis Funds Trusts, Loomis Sayles Funds Trusts and Natixis ETF Trusts, entered into a syndicated, revolving, committed, unsecured line of credit with State Street Bank as administrative agent. The aggregate revolving commitment amount is $575,000,000. Any one Fund may borrow up to $402,500,000 under the line of credit agreement (as long as all borrowings by all Funds in the aggregate do not exceed the $575,000,000 limit at any time), subject to each Fund’s investment restrictions and its contractual obligations under the line of credit. Interest is charged to the Funds based upon the terms set forth in the agreement. In addition, a commitment fee of 0.15% per annum, payable at the end of each calendar quarter, is accrued and apportioned among the participating funds based on their average daily unused portion of the line of credit.

For the six months ended June 30, 2026, Global Megatrends Fund had an average daily balance on the line of credit (for those days on which there were borrowings) of $13,700,000 at a weighted average interest rate of 4.74%. Interest expense incurred on the line of credit was $7,215.

10.Risk. The Funds’ investments in foreign securities may be subject to greater political, economic, environmental, credit/counterparty and information risks. The Fund's investments in foreign securities also are subject to foreign currency fluctuations and other foreign currency-related risks. Foreign securities may be subject to higher volatility than U.S. securities, varying degrees of regulation and limited liquidity.

Geopolitical events (such as trading halts, sanctions or wars) could increase volatility and uncertainty in the financial markets and adversely affect regional and global economies. These, and other related events, could significantly impact a Fund's performance and the value of an investment in the Fund, even if the Fund does not have direct exposure to issuers in the country or countries involved.

11.Concentration of Ownership. From time to time, a Fund may have a concentration of one or more shareholder accounts constituting a significant percentage of shares outstanding. Investment activities by holders of accounts that represent a significant ownership of more than 5% of a Fund’s outstanding shares could have material impacts on a Fund.

Fund	Number of 5% Account Holders	Percentage of Ownership
Gateway Fund	1	5.58 %

Notes to Financial Statements (continued)

June 30, 2026 (Unaudited)

13.Redemption In-Kind. In certain circumstances, a Fund may distribute portfolio securities rather than cash as payment for redemption of Fund shares (redemption in-kind). For financial reporting purposes, the Fund will recognize a gain on in-kind redemptions to the extent the value of the distributed securities on the date of redemption exceeds the cost of those securities; the Fund will recognize a loss if the cost exceeds value. Gains and losses realized on redemptions in-kind are not recognized for tax purposes, and are re-classified from realized gain (loss) to paid-in-capital. For the year ended December 31, 2025, Global Megatrends Fund participated in a redemption in-kind transaction.

BOARD APPROVAL OF THE EXISTING ADVISORY AGREEMENTS

The Board of Trustees of the Trusts (the “Board”), including the Independent Trustees, considers matters bearing on each Fund’s advisory agreement (collectively, the “Agreements”) at most of its meetings throughout the year. Each year, usually in the spring, the Contract Review Committee of the Board meets to review the Agreements to determine whether to recommend that the full Board approve the continuation of the Agreements, for no more than an additional one-year period. This meeting typically includes all the Independent Trustees, including the Trustees who do not serve on the Contract Review Committee. After the Contract Review Committee has made its recommendation, the full Board, including the Independent Trustees, determines whether to approve the continuation of the Agreements at its June Board meeting.

In connection with these meetings, the Trustees receive materials that the Funds’ investment advisers (the “Advisers”) believe to be reasonably necessary for the Trustees to evaluate the Agreements. These materials generally include, among other items, (i) information on the investment performance of the Funds and the performance of peer groups of funds and the Funds’ performance benchmarks, (ii) information on the Funds’ advisory fees and other expenses, including information comparing the Funds’ advisory fees to the fees charged to institutional accounts with similar strategies managed by the Advisers, if any, and to those of peer groups of funds and information about any applicable expense limitations and/or fee “breakpoints,” (iii) sales and redemption data in respect of the Funds, (iv) information about the profitability of the Agreements to the Advisers, including how profitability is determined for the Funds, and (v) information obtained through the completion by the Advisers of questionnaires distributed on behalf of the Trustees throughout the year. The Board, including the Independent Trustees, also considers other matters such as (i) each Fund’s investment objective and strategies and the size, education and experience of the Advisers’ respective investment staffs and their use of technology, external research and trading cost measurement tools, (ii) arrangements in respect of the distribution of the Funds’ shares and the related costs, (iii) the allocation of the Funds’ brokerage, if any, including, to the extent applicable, allocations to brokers affiliated with the Advisers and the use of “soft” commission dollars to pay for research and other similar services, (iv) the Advisers’ policies and procedures relating to, among other things, compliance, trading and best execution, proxy voting, liquidity and valuation, (v) information about amounts invested by the Funds’ portfolio managers in the Funds or in similar accounts that they manage and (vi) the general economic outlook with particular emphasis on the mutual fund industry. Throughout the process, the Trustees are afforded the opportunity to ask questions of and request additional materials from the Advisers and the Independent Trustees meet separately with independent legal counsel outside the presence of Adviser personnel.

In addition to the materials requested by the Trustees in connection with their annual consideration of the continuation of the Agreements, the Trustees receive materials in advance of each regular quarterly meeting of the Board that provide detailed information about the Funds’ investment performance and the fees charged to the Funds for advisory and other services. The information received by the Trustees generally includes, where available, among other things, an internal performance rating for each Fund based on agreed-upon criteria, graphs showing each Fund’s performance and expense differentials against each Fund’s peer group/category of funds, total return information for various periods, performance rankings provided by a third-party data provider for various periods comparing a Fund against similarly categorized funds, and performance ratings provided by a different third-party rating organization. The portfolio management team for each Fund or other representatives of the Advisers make periodic presentations to the Contract Review Committee and/or the full Board, and Funds identified as presenting possible performance concerns may be subject to more frequent Board or Committee presentations and reviews. In addition, the Trustees are periodically provided with detailed statistical information about each Fund’s portfolio. The Trustees also receive periodic updates between meetings, both at the Board and at the Committee level.

The Board most recently approved the continuation of the Agreements for a one-year period at its meeting held in June 2026. In considering whether to approve the continuation of the Agreements, the Board, including the Independent Trustees, did not identify any single factor as determinative. Individual Trustees may have evaluated the information presented differently from one another, giving different weights to various factors. Matters considered by the Trustees, including the Independent Trustees, in connection with their approval of the Agreements included, but were not limited to, the factors listed below.

The nature, extent and quality of the services provided to the Funds under the Agreements. The Trustees considered the nature, extent and quality of the services provided by the Advisers and their affiliates to the Funds and the resources dedicated to the Funds by the Advisers and their affiliates. The Trustees also considered their experience with other funds advised by the Advisers, as well as the affiliation between the Advisers and Natixis Investment Managers, LLC, whose affiliates provide investment advisory services to other funds in the Natixis family of funds.

The Trustees considered not only the advisory services provided by the Advisers to the Funds, but also the benefits to the Funds from the monitoring and oversight services provided by Natixis Advisors, LLC (“Natixis Advisors”). They also considered the administrative and shareholder services provided by Natixis Advisors and its affiliates to the Funds. They also took into consideration the personnel and costs related to preparing for compliance with, and the increases in the services provided required as a result of, new or amended regulatory requirements, such as recent rules relating to, among other topics, privacy, fund marketing and fund names, and anti-money laundering, as well as monitoring proposed rules.

For each Fund, the Trustees also considered the benefits to shareholders of investing in a mutual fund that is part of a family of funds that offers shareholders the right to exchange certain classes of shares of one type of fund for shares of another type of fund, and provides a variety of fund and shareholder services.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the nature, extent and quality of services provided supported the renewal of the Agreements.

Investment performance of the Funds and the Advisers. As noted above, the Trustees received information about the performance of the Funds over various time periods, including information that compared the performance of the Funds to the performance of peer groups and categories of funds and the Funds’ respective performance benchmarks. The Board noted that while it found the data provided by the independent third-party data provider useful, it recognized its limitations, including, in particular, that notable differences may exist between the Funds and the performance comparisons (for example, with respect to investment strategies) and that the results of the performance comparisons may vary depending on (i) the end dates for the performance periods that were selected and (ii) the selection of the performance comparisons. The Trustees also received information about how comparative peer groups and categories are constructed. In addition, the Trustees reviewed data prepared by an independent third-party rating organization that analyzed the performance of the Funds using a variety of performance metrics, including metrics that measured the performance of the Funds on a risk adjusted basis.

The Board noted that, through December 31, 2025, each Fund’s one-, three- and five-year performance, stated as percentile rankings within categories selected by the independent third-party data provider, was as follows (where the best performance would be in the first percentile of its category):

	One-Year	Three-Year	Five-Year
Gateway Fund	41%	40%	40%
Gateway Equity Call Premium Fund	50%	43%	43%
Mirova Global Megatrends Fund	56%	70%	57%

In the case of the Fund that had performance that lagged that of a relevant category median as determined by the independent third-party data provider for all periods, the Board concluded that other factors relevant to performance supported renewal of the Fund’s Agreements. These factors included one or more of the following: (1) that the underperformance was attributable, to a significant extent, to investment decisions (such as security selection or sector allocation) by the Adviser that were consistent with the Fund’s investment objective and policies; (2) that the Fund’s performance ranking relative to its category had improved for each of the last two calendar years; and (3) that the Fund's defensive bias to invest in quality stocks has resulted in positive returns for the last calendar year while limiting exposure to riskier securities. The Board also considered information about the Funds’ more recent performance, including how performance over various periods had been impacted by various factors such as market and economic events.

The Trustees also considered each Adviser’s performance and reputation generally, the performance of the fund family generally, and the historical responsiveness of the Advisers to Trustee concerns about performance and the willingness of the Advisers to take steps intended to improve performance.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the performance of the Funds and the Advisers and/or other relevant factors supported the renewal of the Agreements.

The costs of the services to be provided and profits to be realized by the Advisers and their affiliates from their respective relationships with the Funds. The Trustees considered the fees charged to the Funds for advisory and administrative services as well as the total expense levels of the Funds. This information included comparisons (provided both by management and by an independent third party) of the Funds’ advisory fees and total expense levels to those of their peer groups and information about the advisory fees charged by the Advisers 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, the greater regulatory costs associated with the management of such assets, and the entrepreneurial, regulatory and other risks associated with sponsoring and managing mutual funds. In evaluating each Fund’s advisory fees, the Trustees also took into account the demands, complexity and quality of the investment management of such Fund, and the need for the Advisers to offer competitive compensation and the potential need to expend additional resources to the extent the Fund grows in size. The Trustees considered that over the past several years, management had demonstrated its intention to have competitive fee levels by making recommendations regarding reductions in advisory fee rates, implementation of advisory fee breakpoints and the institution of advisory fee waivers and expense limitations for various funds in the fund family. They noted that all of the Funds included have expense limitations in place, and they considered the amounts waived or reimbursed by the Adviser for all of the Funds under their respective expense limitation agreements. The Trustees further noted that the total advisory fee

| 42

rate for each of Gateway Fund and Gateway Equity Call Premium Fund was at or below the median of its peer group of funds. The Board also considered that the fee and expense information reflected information as of a certain date and that historical asset levels may differ from current asset levels, particularly in a period of market volatility.

The Trustees noted that Mirova Global Megatrends Fund had an advisory fee rate that was above the median of its peer group of funds. In this regard, the Trustees considered the factors that management believed justified such a relatively higher advisory fee rate, including: (1) that the advisory fee was only three basis points higher than the median of a peer group of funds; and (2) that the Fund’s net overall expense ratio was only two basis points above the median of its peer group of funds.

The Trustees also considered the compensation directly or indirectly received by the Advisers and their affiliates from their relationships with the Funds. The Trustees reviewed information provided by management as to the profitability of the Advisers’ and their affiliates’ relationships with the Funds, and information about how expenses are determined and allocated for purposes of profitability calculations. They also reviewed information provided by management about the effect of distribution costs and changes in asset levels on Adviser profitability, including information regarding resources spent on distribution activities. When reviewing profitability, the Trustees also considered information about court cases in which adviser compensation or profitability were issues, the performance of the Funds, the expense levels of the Funds, whether the Advisers had implemented breakpoints and/or expense limitations with respect to such Funds and the overall profit margin of Natixis Investment Managers, LLC compared to that of certain other investment managers for which such data was available. The Board also noted the competitive nature of the global asset management industry.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the advisory fees charged to each of the Funds were fair and reasonable, and that the costs of these services generally and the related profitability of the Advisers and their affiliates in respect of their relationships with the Funds supported the renewal of the Agreements.

Economies of Scale. The Trustees considered the existence of any economies of scale in the provision of services by the Advisers and whether those economies are shared with the Funds through breakpoints in their investment advisory fees or other means, such as expense limitations. The Trustees also considered management’s explanation of the factors that are taken into account with respect to the implementation of breakpoints in investment advisory fees or expense limitations, which reduced the total expenses borne by shareholders. With respect to economies of scale, the Trustees noted that Gateway Fund had breakpoints in its advisory fees and that each of the Funds was subject to an expense limitation. 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 the Advisers and their affiliates of their relationships with the Funds, as discussed above. The Trustees also considered that the Funds have benefitted from the substantial reinvestment certain Advisers had made into their businesses.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the extent to which economies of scale were shared with the Funds supported the renewal of the Agreements.

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

• The effect of various factors and recent market and economic events, such as recent market volatility, geopolitical instability and conflicts, cybersecurity incidents and threats to information systems, including as a result of the proliferation of artificial intelligence, and developments affecting trade policy and global markets generally, as applicable, 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 and the Advisers. They also considered the compliance-related resources the Advisers and their affiliates were providing to the Funds.

• So-called “fallout benefits” to the Advisers, such as the engagement of affiliates of the Advisers to provide distribution and administrative services to the Funds, and the benefits of research made available to the Advisers by reason of brokerage commissions (if any) generated by the Funds’ securities transactions. 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.

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, concluded that each of the existing Agreements should be continued through June 30, 2027.
