Fund Fees & Expenses

The following table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in this table. If such expenses were reflected, the expenses set forth below would be higher.

Annual Fund Operating Expenses


(expenses that you pay each year as a percentage of the value of your investment)
Management fees	0.70%
Distribution and/or service (12b-1) fees	0.00%
Other expenses	0.74%
Total annual fund operating expenses	1.44%
Fee waiver and/or expense reimbursement¹	0.64%
Total annual fund operating expenses after fee waiver and/or expense reimbursement	0.80%

Natixis Advisors, LLC (“Natixis Advisors” or the “Adviser”) has given a binding contractual undertaking to the Fund to limit the amount of the Fund’s total annual fund operating expenses to 0.80% of the Fund’s average daily net assets, exclusive of brokerage expenses, interest expense, taxes, acquired fund fees and expenses, and organizational and extraordinary expenses, such as litigation and indemnification expenses. This undertaking is in effect through April 30, 2027 and may be terminated before then only with the consent of the Fund’s Board of Trustees. The Adviser will be permitted to recover management fees waived and/or expenses reimbursed to the extent that expenses in later periods fall below both (1) the expense limitation ratio in place at the time such amounts were waived/reimbursed and (2) the Fund’s current applicable expense limitation ratio. The Fund will not be obligated to repay any such waived/reimbursed fees and expenses more than one year after the end of the fiscal year in which the fees or expenses were waived/reimbursed.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated (whether or not shares are redeemed), and also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that the example is based on the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement assuming that such waiver and/or reimbursement will only be in place through the date noted above and on the Total Annual Fund Operating Expenses for the remaining periods. The example does not take into account brokerage commissions and other fees to financial intermediaries that you may pay on your purchases and sales of shares of the Fund. It also does not include the transaction fees on purchases and redemptions of creation units (“Creation Units”), because those fees will not be imposed on retail investors. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:


If shares are redeemed:	1 year		3 years		5 years		10 years
	$	82	$	255	$	593	$	1,548

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During its most recently ended fiscal year, the Fund’s portfolio turnover rate was 47% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

The Fund, under normal market conditions, will invest primarily in equity securities, including common stocks, preferred stocks and real estate investment trusts (“REITs”). The Fund is non-diversified, which means that it may invest a greater percentage of its assets in a particular issuer and may invest in fewer issuers than a diversified fund. Typically, the Fund’s portfolio will generally hold 20 to 40 securities. The Fund may invest in companies with any market capitalization, although, it will typically focus its investments in mid- to large-capitalization companies. A company will be considered to be a mid- to large-capitalization company if its capitalization is $5 billion or higher.

Vaughan Nelson Investment Management, L.P. (“Vaughan Nelson” or the “Subadviser”) invests in companies of all market capitalizations with a focus on those companies meeting Vaughan Nelson’s return expectations.

Vaughan Nelson uses a bottom-up value oriented investment process in constructing the Fund’s portfolio. Vaughan Nelson seeks companies with the following characteristics, although not all of the companies selected will have these attributes:

•	Companies earning a positive return on capital with stable-to-improving returns.

•	Companies valued at discount to their asset value.

•	Companies with an attractive and sustainable dividend level.

In selecting investments for the Fund, Vaughan Nelson generally employs the following strategies:

•	Vaughan Nelson employs a value-driven investment philosophy that selects securities selling at a relatively low value based on discounted cash flow models. Vaughan Nelson selects companies that it believes are out-of-favor or misunderstood.

•	Vaughan Nelson starts with the entire U.S. equity investment universe. Vaughan Nelson then narrows the investment universe by using fundamental analysis to construct a portfolio of generally 20 to 40 securities.

•	Vaughan Nelson uses fundamental analysis to construct a portfolio that, in the opinion of Vaughan Nelson, is made up of quality companies with the potential to provide significant increases in share price over a three year period.

•	Vaughan Nelson will generally sell a security when it reaches Vaughan Nelson’s price target or when the issuer shows a change in financial condition, competitive pressures, poor management decisions or internal or external forces reducing future expected returns from the investment thesis.

Principal Investment Risks

The principal risks of investing in the Fund are summarized below. The Fund does not represent a complete investment program. You may lose money by investing in the Fund.

Fund shares are not bank deposits and are not guaranteed, endorsed or insured by the Federal Deposit Insurance Corporation or any other government agency, and are subject to investment risks, including possible loss of the principal invested.

The significance of any specific risk to an investment in the Fund will vary over time, depending on the composition of the Fund’s portfolio, market conditions, and other factors. You should read all of the risk information presented below carefully, because any one or more of these risks may result in losses to the Fund.

Equity Securities Risk: The value of the Fund’s investments in equity securities could be subject to unpredictable declines in the value of individual securities and periods of below-average performance in individual securities or in the equity market as a whole. Value stocks can perform differently from the market as a whole and from other types of stocks. Value stocks also present the risk that their lower valuations fairly reflect their business prospects and that investors will not agree that the stocks represent favorable investment opportunities, and they may fall out of favor with investors and underperform growth stocks during any given period. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of the issuer’s bonds generally take precedence over the claims of those who own preferred stock or common stock. Securities of real estate-related companies and REITs in which the Fund may invest may be considered equity securities, thus subjecting the Fund to the risks of investing in equity securities generally.

Non-Diversification Risk: Compared with diversified ETFs, the Fund may invest a greater percentage of its assets in a particular issuer and may invest in fewer issuers. Therefore, the Fund may have more risk because changes in the value of a single security or the impact of a single economic, political or regulatory occurrence may have a greater adverse impact on the Fund’s net asset value.

Market/Issuer Risk: The market value of the Fund’s investments will move up and down, sometimes rapidly and unpredictably, based upon overall market and economic conditions, as well as a number of reasons that directly relate to the issuers of the Fund’s investments, such as management performance, financial condition and demand for the issuers’ goods and services.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares or the Fund’s underlying portfolio securities, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. Any of these factors, among others, may lead to the Fund’s shares trading at a premium or discount to NAV. Accordingly, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV, or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Management Risk: A strategy used by the Fund’s portfolio managers may fail to produce the intended result.

Authorized Participant Concentration Risk: Only an authorized participant (“Authorized Participant”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as Authorized Participants, none of which are or will be obligated to engage in creation or redemption transactions. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, the Fund’s shares may trade at a discount to net asset value (“NAV”) and possibly face trading halts and/or delisting.

Cybersecurity and Technology Risk: The Fund, its service providers, market makers, listing exchange, Authorized Participants and other market participants increasingly depend on complex information technology and communications systems, which are subject to a number of different threats and risks that could adversely affect the Fund and its shareholders. Cybersecurity and other operational and technology issues may result in financial losses to the Fund and its shareholders.

Liquidity Risk: Liquidity risk is the risk that the Fund may be unable to find a buyer for its investments when it seeks to sell them or to receive the price it expects. Decreases in the number of financial institutions willing to make markets in the Fund’s investments or in their capacity or willingness to transact may increase the Fund’s exposure to this risk. Events that may lead to increased redemptions, such as market disruptions or increases in interest rates, may also negatively impact the liquidity of the Fund’s investments when it needs to dispose of them. Markets may become illiquid quickly. If the Fund is forced to sell its investments at an unfavorable time and/or under adverse conditions in order to meet redemption requests, such sales could negatively affect the Fund. During times of market turmoil, there may be no buyers or sellers for securities in certain asset classes. In other circumstances, liquid investments may become illiquid. Liquidity issues may also make it difficult to value the Fund’s investments. The Fund may invest in liquid investments that become illiquid due to financial distress, or geopolitical events such as sanctions, trading halts or wars.

New and Smaller Sized Fund Risk: The Fund is relatively new and has a limited operating history for investors to evaluate and may not be successful in implementing its investment strategies. The Fund may fail to attract sufficient assets to achieve or maintain economies of scale, which could result in the Fund being liquidated at any time without shareholder approval and at a time that may not be favorable for all shareholders. Smaller ETFs will have a lower public float and lower trading volumes, leading to wider bid/ask spreads.

Operational Risk: The Fund is exposed to operational risk arising from a number of factors, including but not limited to human error, processing and communication errors, errors of the Fund’s service providers, market makers, listing exchange, Authorized Participants or the issuers of securities in which the Fund invests or with which they do business, failed or inadequate processes and technology or systems failures.

Premium/Discount Risk: Shares of the Fund are listed for trading on the NYSE Arca, Inc. (the “NYSE Arca”) and are bought and sold in the secondary market at market prices that may differ from their most recent NAV. The market value of the Fund’s shares will fluctuate, in some cases materially, in response to changes in the Fund’s NAV, the intraday value of the Fund’s holdings, and the relative supply and demand for the Fund’s shares on the exchange. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for shares may result in shares trading at a significant premium or discount to NAV and/or in a reduced liquidity of your investment. During such periods, you may be unable to sell your shares or may incur significant losses if you sell your shares. There are various methods by which investors can purchase and sell shares and various types of orders that may be placed. Investors should consult their financial intermediary before purchasing or selling shares of the Fund. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

REITs Risk: Investments in the real estate industry, including REITs, are particularly sensitive to economic downturns and are sensitive to factors such as changes in real estate values, property taxes and tax laws, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use and rents and the management skill and creditworthiness of the issuer. Companies in the real estate industry also may be subject to liabilities under environmental and hazardous waste laws. In addition, the value of a REIT is affected by changes in the value of the properties owned by the REIT or mortgage loans held by the REIT. REITs are also subject to default and prepayment risk. Many REITs are highly leveraged, increasing their risk. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Secondary Market Trading Risk: Investors buying or selling shares of the Fund in the secondary market will pay brokerage commissions or other charges imposed by broker-dealers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of shares.

Trading Issues Risk: Trading in Fund shares on the NYSE Arca may be halted in certain circumstances. There can be no assurance that the requirements of the NYSE Arca necessary to maintain the listing of the Fund will continue to be met.

Purchase and Sale of Fund Shares

The Fund will issue and redeem shares at NAV only in large blocks of shares, typically 10,000 shares, called “Creation Units.” Only a few financial institutions that are Authorized Participants are authorized to purchase and redeem Creation Units directly with the Fund. Creation Units are typically issued and redeemed in exchange for cash and/or the deposit or delivery of a basket of securities specified each day by the Fund as the securities in exchange for which the Fund will issue or redeem shares. Except when aggregated in Creation Units, shares are not redeemable securities of the Fund. The number of shares comprising a Creation Unit may change from time to time.

Individual shares of the Fund may only be purchased and sold in secondary market transactions through broker-dealers. Shares of the Fund are listed for trading on the NYSE Arca, and because shares trade at market prices rather than NAV, shares of the Fund may trade at a price greater than NAV (a premium) or less than NAV (a discount).

You may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (“the bid/ask spread”). For more information, including recent information (when available) regarding the Fund’s NAV, market price, premiums and discounts, and bid/ask spreads, please visit the Fund’s website at im.natixis.com.
