Investment Objective

The GMO Systematic Investment Grade Credit ETF (the "Fund") seeks total return in excess of the Bloomberg U.S. Corporate Index.

Fees and Expenses

The table below describes the fees and expenses that you may pay if you buy, hold or 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 the table and Example below.

Annual Fund Operating Expenses (Expenses that you pay each year as a percentage of the value of your investment)
Management fee			0.25	%
Distribution and service (12b-1) fees			0.00	%
Other expenses			0.00	%
Total annual Fund operating expenses			0.25	%

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 and then sell or hold all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year				3 Years
$	26			$	80

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 may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example above, affect the Fund's performance. For the fiscal period June 4, 2025 (commencement of operations) through June 30, 2025, the Fund's portfolio turnover rate was 0% of the average value of its portfolio.

Principal Investment Strategies

The Fund is an actively managed exchange-traded fund ("ETF") that seeks to achieve its investment objective by investing primarily in U.S. investment grade debt securities. GMO determines Fund investments utilizing its proprietary systematic investment approach analyzing bonds based on factors including value, quality, momentum, and company fundamentals. These factors are captured through proprietary fair value models, measures of changes in default risk, and bond and equity momentum indicators. The strategy seeks to invest in attractive risk/return opportunities and limit tracking error by managing the Fund's exposure at the country, sector, and issuer levels and to risks such as liquidity, interest-rates, and credit spreads. The Fund expects to have material exposure to bonds issued by U.S. and non-U.S. companies.

As an alternative to investing directly in bonds, the Fund may invest in exchange-traded and over-the-counter (OTC) derivatives and exchange-traded funds (ETFs). The Fund also may invest in derivatives and ETFs in an attempt to obtain or adjust elements of its long or short investment exposure. Derivatives used may include options, futures, forward currency contracts, and swap contracts.

Under normal circumstances, the Fund invests directly and indirectly (through underlying funds or derivatives) at least 80% of its assets in investment grade debt securities.

The Fund also may invest in the GMO U.S. Treasury Fund, a mutual fund advised by GMO, or in money market funds unaffiliated with GMO, and directly in the types of investments typically held by money market funds.

Principal Risks of Investing in the Fund

The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly. Many factors can affect this value, and you may lose money by investing in the Fund or your investment in the Fund could underperform other investments. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. The principal risks of investing in the Fund are summarized below and are all considered a "principal risk of investing in the Fund regardless of the order in which it appears. For a more complete discussion of these risks, see "Additional Principal Risk Information."

●

Credit Risk - The Fund runs the risk that the issuer or guarantor of a fixed income investment (including a sovereign or quasi-sovereign debt issuer) or the obligor of an obligation underlying an asset-backed security will be unable or unwilling to satisfy its obligation to pay principal and interest or otherwise to honor its obligations in a timely manner or at all. The market price of a fixed income investment will normally decline as a result of the failure of an issuer, guarantor, or obligor to meet its payment obligations or in anticipation of such a failure.

●

Market Risk - Fixed Income - The market price of a fixed income investment can decline due to market-related factors, including rising interest or inflation rates and widening credit spreads, or decreased liquidity due, for example, to market uncertainty about the value of a fixed income investment (or class of fixed income investments).

●

Management and Operational Risk - The Fund runs the risk that GMO's investment techniques will fail to produce intended results. GMO uses quantitative models as part of its investment process. GMO's models may not accurately predict future market movements. In addition, GMO's models rely on assumptions and data that are subject to limitations (e.g., inaccuracies, staleness) that could adversely affect their predictive value. The Fund also runs the risk that GMO's assessment of an investment, including a security's fundamental fair (or intrinsic) value, is wrong or that deficiencies in GMO's or another service provider's internal systems or controls will cause losses for the Fund or impair Fund operations.

●

Derivatives and Short Sales Risk - The use of derivatives involves the risk that their value may not change as expected relative to changes in the value of the underlying assets, pools of assets, rates, currencies or indices. Derivatives also present other risks, including market risk, illiquidity risk, currency risk, credit risk, leveraging risk, commodities risk and counterparty risk. The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in such indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index or underlying securities. The Fund typically creates short investment exposure by selling securities short or by taking a derivative position in which the value of the derivative moves in the opposite direction from the price of an underlying asset, pool of assets, rate, currency or index. Specifically, the net asset value of the Fund's shares will be adversely affected if the equities or other assets that are the subject of the Fund's short exposures appreciate in value. The risk of loss associated with derivatives that provide short investment exposure and short sales of securities is theoretically unlimited. The purchaser of TBA securities generally is subject to higher market risk and interest rate risk, because the delivered securities may be less favorable than anticipated by the purchaser.

●

Illiquidity Risk - Low trading volume, lack of a market maker, large position size, or legal restrictions increase the risk that the Fund or an underlying fund is limited or prevented from selling particular securities or closing derivative positions at desirable prices at a particular time or at all.

●

Futures Contracts Risk - The loss to the Fund resulting from its use of futures contracts is potentially unlimited. Futures markets are highly volatile, and the use of futures contracts increases the volatility of the Fund's net asset value. A liquid secondary market may not exist for any particular futures contract at any particular time, and the Fund may be unable when it wishes to terminate its exposure under that contract. When the Fund uses futures contracts for hedging purposes, it runs the risk that changes in the prices of the contracts will not correlate perfectly with changes in the securities, index, or other asset underlying the contracts or movements in the prices of the Fund's investments that are subject to the hedge. In addition, the Fund may be unable to recover or may be delayed in recovering margin or other amounts deposited with a futures commission merchant or futures clearinghouse. Foreign futures contracts are often less liquid and more volatile than U.S. futures contracts.

●

Non-U.S. Investment Risk - The market prices of many non-U.S. securities fluctuate more than those of U.S. securities. Many non-U.S. securities markets are less stable, smaller, less liquid, and less regulated than U.S. securities markets, and the cost of trading in those markets often is higher than in U.S. securities markets. In addition, non-U.S. securities issuers often are not subject to as much regulation as U.S. issuers, and the reporting, recordkeeping, accounting, custody, and auditing standards to which those issuers are subject often are not as rigorous as U.S. standards. In addition, the Fund is subject to taxation by countries other than the United States, including potentially on a retroactive basis, on (i) capital gains it realizes or dividends, interest, or other amounts it realizes or accrues in respect of non-U.S. investments; (ii) transactions in those investments; and (iii) repatriation of proceeds generated from the sale or other disposition of those investments. Also, the Fund needs a license to invest directly in securities traded in many non-U.S. securities markets, and the Fund is subject to the risk that its license is terminated or suspended. In some non-U.S. securities markets, prevailing custody and trade settlement practices (e.g., the requirement to pay for securities prior to receipt) expose the Fund to credit and other risks. Further, adverse changes in investment regulations, capital requirements or exchange controls could adversely affect the value of the Fund's investments. The risks above (such as substantial price fluctuations and market instability, illiquidity and lack of regulation) and other risks (e.g., nationalization, expropriation or other confiscation of assets of non-U.S. issuers, difficulties enforcing legal judgments or contractual rights and geopolitical risks) tend to be higher for investments in the securities of issuers tied economically to emerging countries. The economies of emerging countries often depend predominantly on only a few industries or commodities and often are more volatile than the economies of developed countries.

●

Counterparty Risk - The Fund runs the risk that the counterparty to a derivatives contract or a clearing member used by the Fund to hold a cleared derivatives contract is unable or unwilling to make timely settlement payments, return the Fund's collateral or otherwise honor its obligations.

●

Focused Investment Risk - Investments in countries, regions, asset classes, sectors, industries, currencies, or issuers that are subject to the same or similar risk factors and investments whose market prices are closely correlated, such as the Fund's investments in non-U.S. government bonds and asset-backed securities secured by different types of consumer debt (e.g., credit-card receivables, automobile loans, and home equity loans), are subject to higher overall risk than investments that are more diversified or whose market prices are not as closely correlated.

●

Leveraging Risk - The use of derivatives, short sales and securities lending can create leverage. Leverage increases the Fund's losses when the value of its investments (including derivatives) declines. In addition, the Fund's portfolio will be leveraged if it exercises its right to delay payment on a redemption and the value of the Fund's assets declines between the time a redemption request is treated as being received by the Fund and the time the Fund liquidates assets to fund that redemption.

●

Large Shareholder Risk - To the extent that a large number of shares of the Fund is held by a single shareholder (e.g., an institutional investor or another GMO Fund) or a group of shareholders with a common investment strategy (e.g., GMO asset allocation accounts), the Fund is subject to the risk that a redemption by that shareholder or group will require the Fund to sell investments at disadvantageous prices, disrupt the Fund's operations, or force the Fund's liquidation.

●

Market Disruption and Geopolitical Risk - Geopolitical and other events (e.g., wars, pandemics, sanctions, terrorism) often disrupt securities markets and adversely affect the general economy or particular economies and markets. Those events, as well as other changes in non-U.S. and U.S. economic and political conditions, could exacerbate other risks or otherwise reduce the value of the Fund's investments.

●

Smaller Company Risk - Smaller companies may have limited product lines, markets, or financial resources, lack the competitive strength of larger companies, have less experienced managers or depend on a few key employees. The securities of companies with smaller market capitalizations often are less widely held and trade less frequently and in lesser quantities, and their market prices often fluctuate more, than the securities of companies with larger market capitalizations.

●

ETF Risks - The Fund is an ETF and, as a result of this structure, is exposed to the following risks:

o

Costs of Buying or Selling Shares Risk. Due to the costs of buying or selling Fund shares, including brokerage commissions imposed by brokers and the variance in bid-ask spreads, frequent trading of Fund shares may significantly reduce investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

o

Limited Authorized Participants, Market Makers and Liquidity Providers Risk. Because the Fund is an ETF, typically only a limited number of institutional investors (known as "Authorized Participants") are authorized to purchase and redeem shares directly from the Fund. Retail investors cannot transact directly with the Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace to transact in Fund shares, there may be demand for Fund shares thereby increasing the market price above NAV, or lack of demand, which may decrease the market price below NAV, or in stressed market conditions, the market for Fund shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings. As a result of these considerations, Fund shares may trade at a material premium or discount to net asset value ("NAV") or these factors may, in turn, lead to wider spreads between the bid and ask price of Fund shares. In addition, the Fund may face possible delisting if: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

o

Trading Risk. Shares of the Fund may trade on the NYSE Arca, Inc. (the "Exchange") above (premium) or below (discount) their NAV. In stressed market conditions, the market for Fund shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings, which may increase the variance between the market price of the Fund shares and the value of its underlying holdings. This can be reflected as a spread between the bid and ask prices for the Fund shares quoted during the day or a premium or discount in the closing price from the Fund's NAV. In addition, although the Fund's shares are currently listed on the Exchange, there can be no assurance that an active trading market for Fund shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable.

o

Cash Transactions Risk. The Fund may effect some of its creations and redemptions for cash, rather than in-kind securities. As a result, the Fund may have to sell portfolio securities at inopportune times in order to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. The use of cash creations and redemptions may also cause the Fund's shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund's NAV. In effecting creations and redemptions in exchange for cash, the Fund may incur certain costs, including brokerage costs in connection with investing cash received and may recognize capital gains in connection with cash redemptions, unlike an ETF that effects creations and redemptions only in-kind. In addition, costs could be imposed on the Fund which would have the effect of decreasing the Fund's NAV to the extent the costs are not offset by a transaction fee payable by an Authorized Participant.

●

New/Smaller Fund Risk - A new or smaller fund is subject to the risk that its performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new and smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. There can be no assurance that the Fund will achieve an economically viable size, in which case it could ultimately liquidate.

Purchase and Sale of Fund Shares

The Fund issues shares to, and redeems shares from, certain institutional investors known as "Authorized Participants" (typically market makers or other broker-dealers) only in large blocks of Fund shares known as "Creation Units." Creation Unit transactions are generally conducted in exchange for the deposit or delivery of a portfolio of in-kind securities designated by the Fund, cash or a combination of securities and cash.

Individual Fund shares may only be purchased and sold in the secondary market through a broker or dealer at a market price. Because Fund shares trade at market prices rather than at NAV, Fund shares may trade at a price greater than NAV (premium) or less than NAV (discount). When buying or selling shares in the secondary market, 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) (the "bid-ask spread"). When available, recent information regarding the Fund's NAV, market price, premiums and discounts, and bid-ask spreads will be available at https://www.gmo.com/americas/investment-capabilities/etfs.

U.S. Tax Information

The Fund intends to elect to be treated, and intends to qualify and be treated each year, as a regulated investment company (a "RIC") under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") for U.S. federal income tax purposes and to distribute net investment income and net realized capital gains, if any, to shareholders.

Distributions made by the Fund may be taxable as ordinary income, qualified dividend income (if applicable), or long-term capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or individual retirement account. In that case, you may be taxed when you take a distribution from such account, depending on the type of account, the circumstances of your distribution, and other factors.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Fund shares through a broker-dealer or other financial intermediary (such as a bank), GMO or its affiliates may pay the financial intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
