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 when 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 the most recent

fiscal year, the Fund's portfolio turnover rate was 77.56% of the average value of its portfolio.

The following bar chart and table provide some indication of the risks of investing in the Fund. The Fund adopted the performance of the BrandywineGLOBAL—Dynamic US Large Cap Value Fund (the “predecessor mutual fund”) as the result of a reorganization of the predecessor mutual fund into the Fund that was effective after the market close on October 28, 2022 (the “Reorganization”). Prior to the Reorganization, the Fund had not yet commenced operations. The returns shown for periods ending on or prior to October 28, 2022 are those of the predecessor mutual fund. The bar chart shows changes in the Fund’s (and the predecessor mutual fund’s) performance from year to year (predecessor mutual fund performance is represented by the performance of the predecessor mutual fund’s

Class IS Shares). The table shows how the Fund’s (and the predecessor mutual fund’s) average annual returns (in the case of the predecessor mutual fund, the average annual returns of the predecessor mutual fund’s Class IS Shares) for 1 year, 5 years and 10 years compared with those of a broad measure of market performance and additional indexes with characteristics relevant to the Fund.

Had the predecessor mutual fund been structured as an ETF, its performance may have differed. The Fund’s (and the predecessor mutual fund’s) past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Principal Risks

You could lose money by investing in the Fund. ETF shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value (NAV), trading price, yield, total return and ability to meet its investment goal. Unlike many ETFs, the Fund is not an index-based ETF.

Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise. In addition, the value of the Fund’s investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest, inflation or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in additional tariffs, trade barriers and/or investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economic prospects of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.

Stock prices tend to go up and down more dramatically than those of debt securities. A slower-growth or recessionary economic environment could have an adverse effect on the prices of the various stocks held by the Fund.

Quantitative Models: The quantitative models that may be used by the sub-advisor as part of the Fund’s portfolio construction process to evaluate investment opportunities have been tested on historical price data. These models are based on the assumption that price movements in most markets display similar patterns. There is the risk that market behavior will change and that the patterns upon which the forecasts in the models are based will weaken or disappear, which would reduce the ability of the models to generate an excess return. Further, as market dynamics shift over time, a previously highly successful model may become outdated, perhaps without the sub-advisor recognizing that fact before substantial losses are incurred. Successful operation of a model is also reliant upon the information technology systems of the sub-advisor and its ability to ensure those systems remain operational and that appropriate disaster recovery procedures are in place. There can be no assurance that the sub-advisor will be successful in maintaining effective and operational quantitative models and the related hardware and software systems.

Industrials companies: The stock prices of companies in the industrials sector are affected by supply and demand both for their specific product or service and for industrials sector products in general. Companies in the industrials sector may be adversely affected by changes in government regulation, world events and economic conditions. In addition, these companies are at risk for environmental damage and product liability claims. Companies in this sector could be adversely affected by commodity price volatility, changes in exchange rates, imposition of export or import controls, increased competition, depletion of resources, technological developments and labor relations.

Portfolio Turnover: Active and frequent trading may increase a shareholder’s tax liability and the Fund’s transaction costs, which could detract from Fund performance.

Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, the sub-advisor, authorized participants, or index providers (as applicable) and listing exchanges, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming shares or receiving distributions. The investment manager and the sub-advisor have limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund, the investment manager or the sub-advisor. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, the sub-advisor, and their service providers are subject to the risk of cyber incidents occurring from time to time.

Authorized Participant Concentration: Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. "Authorized Participants" are broker-dealers that are permitted to create and redeem shares directly with the Fund and who have entered into agreements with the Fund’s distributor. The Fund has a limited number of institutions that act as Authorized Participants. 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 (as defined below), Fund shares may trade at a discount to NAV and possibly face trading halts and/or delisting. This risk may be more pronounced in volatile markets, potentially where there are significant redemptions in ETFs generally.

Large Shareholder: Certain large shareholders, including other funds or accounts advised by the investment manager, sub-advisor or an affiliate of the investment manager or sub-advisor, may from time to time own a substantial amount of the Fund’s shares. In addition, a third-party investor, the investment manager, sub-advisor or an affiliate of the investment manager or sub-advisor, an authorized participant, a lead market maker, or another entity may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.
