In accordance with the authoritative guidance on fair value measurements and disclosure under U.S. GAAP, the Funds disclose fair value of its investments in a hierarchy that prioritizes the inputs to valuation techniques used to measure the fair value. The objective of a fair value measurement is to determine the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date (an exit price). Accordingly, the fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).

The three levels of the fair value hierarchy are described below:

•    Level 1 — Unadjusted quoted prices in active markets for identical, unrestricted assets or liabilities that the Funds have the ability to access at the measurement date;

•    Level 2 — Quoted prices which are not active, or inputs that are observable (either directly or indirectly) for substantially the full term of the asset or liability; and

•    Level 3 — Prices, inputs or proprietary modeling techniques which are both significant to the fair value measurement and unobservable (supported by little or no market activity).

The valuation techniques used by the Funds to measure fair value during the six months ended May 31, 2026 maximized the use of observable inputs and minimized the use of unobservable inputs. Investments are classified within the level of the lowest significant input considered in determining fair value.

Federal Income Taxes — It is each Fund’s intention to qualify as a regulated investment company for Federal income tax purposes by complying with the appropriate provisions of Subchapter M of the Internal Revenue Code of 1986, as amended. Accordingly, no provisions for Federal income taxes have been made in the financial statements.

Each Fund’s policy is to classify interest and penalties associated with underpayment of federal and state income taxes, if any, as income tax expense on their Statements of Operations. As of May 31, 2026, the Funds did not have any interest or penalties associated with the underpayment of any income taxes. Current tax years, the last three tax year ends, remain open and subject to examination by tax jurisdictions. The Funds have reviewed all major jurisdictions and concluded that there is no impact on the Funds’ net assets and no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken on its tax returns.

Foreign Taxes — The Funds may be subject to taxes imposed by countries in which it invests. Such taxes are generally based on either income or gains earned or repatriated. The Funds accrue and apply such taxes to net investment income, net realized gains and net unrealized gains as income and/or capital gains earned.

Security Transactions and Investment Income — Security transactions are accounted for on trade date. Costs used in determining realized gains and losses on the sale of investment securities are based on specific identification. Dividend income is recorded on the ex-dividend date. Interest income is recognized on the accrual basis. Withholding taxes and reclaims on foreign dividends, if any, have been provided for in accordance with the Funds’ understanding of the applicable country’s tax rules and rates.

Foreign Currency Translation — The books and records of the Funds are maintained in U.S. dollars. Investment securities and other assets and liabilities denominated in a foreign currency are translated into U.S. dollars on the date of valuation. Purchases and sales of investment securities, income and expenses are translated into U.S. dollars at the relevant rates of exchange prevailing on the respective dates of such transactions. The Funds do not isolate that portion of realized or unrealized gains and losses resulting from changes in the foreign exchange rate from fluctuations arising from changes in the market prices of the securities. These gains and losses are included in net realized and unrealized gains and losses on investments on the Statements of Operations. Net realized and unrealized gains and losses on foreign currency transactions represent net foreign exchange gains or losses from foreign currency exchange contracts, disposition of foreign currencies, currency gains or losses realized between trade and settlement dates on securities transactions and the difference between the amount of the investment

income and foreign withholding taxes recorded on the Funds’ books and the U.S. dollar equivalent amounts actually received or paid. The Funds may be subject to foreign taxes related to foreign income received, capital gain on the sale of securities and certain foreign currency transactions (a portion of which may be reclaimable). All foreign taxes are recorded in accordance with the applicable regulations and rates that exist in the foreign jurisdictions in which the Funds invest.

Cash and Cash Equivalents — Idle cash may be swept into various overnight demand deposits and is classified as Cash and Cash equivalents on the Statements of Assets and Liabilities, if any. The Funds maintain cash in bank deposit accounts which, at times, may exceed United States federally insured limits. Amounts swept overnight are available on the next business day.

Dividends and Distributions to Shareholders — Each Fund pays out dividends from its net investment income and distributes its net capital gains, if any, to investors at least annually. All distributions are recorded on ex-dividend date.

Creation Units — The Funds issue and redeem shares at NAV and only in Creation Units, or multiples thereof. Purchasers of Creation Units (“Authorized Participants”) at NAV must pay a standard creation transaction fee, regardless of the number of Creation Units created in a given transaction. An Authorized Participant who holds Creation Units and wishes to redeem at NAV would also pay a standard minimum redemption transaction fee to the custodian on the date of such redemption, regardless of the number of Creation Units redeemed in a given transaction. The Funds may charge, either in lieu of or in addition to the fixed creation transaction fee, a variable fee for creations and redemptions in order to cover certain non-standard brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from such transactions. In all cases, such fees will be limited in accordance with the requirements of the Commission applicable to management investment companies offering redeemable securities.

The Adviser may retain all or a portion of the transaction fee to the extent the Adviser bears the expenses that otherwise would be borne by the Trust in connection with the purchase or redemption of a Creation Unit, which the transaction fee is designed to cover.

Except when aggregated in Creation Units, shares are not redeemable securities of the Funds. Shares of the Funds may only be purchased or redeemed by certain Authorized Participants. An Authorized Participant is either (i) a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the National Securities Clearing Corporation or (ii) a Depository Trust Company (“DTC”) participant and, in each case, must have executed an Authorized Participant Agreement with the Funds’ distributor. Most retail investors will not qualify as Authorized Participants or have the resources to buy and sell whole Creation Units. Therefore, they will be unable to purchase or redeem the shares directly from the Funds. Rather, most retail investors will purchase and sell shares in the secondary market with the assistance of a broker and will be subject to customary brokerage commissions or fees.

To the extent contemplated by an Authorized Participant Agreement, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the shares comprising a Creation Unit to be redeemed to SEI Investments Distribution Co. (the “Distributor”), on behalf of a Fund, by the time as set forth in the Authorized Participant Agreement, the Distributor may nonetheless accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible, which undertaking shall be secured by the Authorized Participant’s delivery and maintenance of collateral equal to a percentage of the value of the missing shares as specified in the Authorized Participant Agreement. An Authorized Participant Agreement may permit a Fund to use such collateral to purchase the missing shares, and could subject an Authorized Participant to liability for any shortfall between the cost of a Fund acquiring such shares and the value of the collateral. Amounts are disclosed as Segregated Cash Balance from Authorized Participants for Deposit Securities and Collateral Payable upon Return of Deposit Securities on the Statements of Assets and Liabilities, when applicable.

5. TAX INFORMATION

The amount and character of income and capital gain distributions to be paid, if any, are determined in accordance with Federal income tax regulations, which may differ from U.S. GAAP. As a result, net investment income (loss) and net realized gain (loss) on investment transactions for a reporting period may differ significantly from distributions during such period. These book/tax differences may be temporary or permanent. To the extent these differences are permanent in nature, they are charged or credited to paid-in capital or total distributable earnings (accumulated losses) as appropriate, in the period that the differences arise.

The tax character of dividends and distributions paid during the years ended November 30, 2025 and November 30, 2024 were as follows:

As of November 30, 2025, the components of Distributable Earnings (Accumulated Losses) on a tax basis were as follows:

The Funds are permitted to utilize capital losses that are carried forward and will retain their character as either short-term or long-term capital losses. As of November 30, 2025, the following Funds had capital loss carryforwards to offset capital gains for an unlimited period:

6. PRINCIPAL RISKS OF INVESTING IN THE FUNDS

As with all exchange traded funds (“ETFs”), each shareholder of a Fund is subject to the risk that their investment could lose money. The Funds are subject to the principal risks noted below, any of which may adversely affect a Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. Risk information is applicable to each Fund unless otherwise noted. Additional principal risks are disclosed in the Funds’ prospectus. Please refer to the Funds’ prospectus for a complete description of the principal risks of investing in a Fund.

Limited Authorized Participants, Market Makers and Liquidity Providers Risk. Because each Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Funds. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occurs, the risk of which is higher during periods of market stress, shares of the Funds may trade at a material discount to their NAV per share and possibly face delisting, and may experience wide bid-ask spreads: (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.

Currency Exchange Rate Risk. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of a Fund’s investments and the value of your shares. Because each Fund’s NAV is determined on the basis of U.S. dollars, the U.S. dollar value of your investment in a Fund may go down if the value of the local currency of the non-U.S. markets in which that Fund invests depreciates against the U.S. dollar. This is true even if the local currency value of securities in a Fund’s holdings goes up. Conversely, the dollar value of your
investment in a Fund may go up if the value of the local currency appreciates against the U.S. dollar. The value of the U.S. dollar measured against other currencies is influenced by a variety of factors. These factors include: national debt levels and trade deficits, changes in balances of payments and trade, domestic and foreign interest and inflation rates, global or regional political, economic or financial events, monetary policies of governments, actual or potential government intervention, and global energy prices. Political instability, the possibility of government intervention and restrictive or opaque business and investment policies may also reduce the value of a country’s currency. Government monetary policies and the buying or selling of currency by a country’s government may also influence exchange rates. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in a Fund may change quickly and without warning, and you may lose money.

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to expropriation, nationalization or adverse political or economic developments. Foreign securities may have relatively low market liquidity and decreased publicly available information about issuers. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. Non-U.S. issuers may also be subject to inconsistent and potentially less stringent accounting, auditing, financial reporting and investor protection standards than U.S. issuers. These and other factors can make investments in each Fund more volatile and potentially less liquid than other types of investments. In addition, where all or a portion of the Funds’ portfolio holdings trade in markets that are closed when the Funds’ market is open, there may be valuation differences that could lead to differences between each Fund’s market price and the value of its portfolio holdings.

Sector Focus Risk. A Fund may invest a significant portion of its assets in one or more sectors and thus will be more susceptible to the risks affecting those sectors. While each Fund’s sector exposure is expected to vary over time based on the composition of its Index, each Fund anticipates that it may be subject to some or all of the risks described below.

Energy Sector Risk. The market value of securities in the energy sector may decline for many reasons including, fluctuations in energy prices and supply and demand of energy fuels caused by geopolitical events, the success of exploration projects, weather or meteorological events, taxes, increased governmental or environmental regulation, resource depletion, rising interest rates, declines in domestic or foreign production, accidents or catastrophic events that result in injury, loss of life or property, pollution or other environmental damage claims, terrorist threats or attacks, among others. Markets for various energy-related commodities can have significant volatility and are subject to control or manipulation by large producers or purchasers. Companies in the energy sector may need to make substantial expenditures, and may incur significant amounts of debt, to maintain or expand their reserves through exploration of new sources of supply, through the development of existing sources, through acquisitions, or through long-term contracts to acquire reserves. Factors adversely affecting producers, refiners, distributors, or others in the energy sector may adversely affect companies that service or supply those entities, either because demand for those services or products is curtailed, or those services or products come under price pressure. Issuers in the energy sector may also be impacted by changing investor and consumer preferences arising from the sector’s potential exposure to sustainability and environmental concerns.

Industrials Sector Risk. Stock prices for industrials companies are affected by supply and demand both for their specific product or service and for industrials sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies.

Materials Sector Risk. Companies in the materials sector may be adversely impacted by the volatility of commodity prices, changes in exchange rates, depletion of resources, over-production, litigation and changes in government regulations, among other factors.

Utilities Sector Risk. The utilities sector is subject to significant government regulation and oversight. Deregulation, however, may subject utility companies to greater competition and may reduce their profitability. Companies in the utilities sector may be adversely affected due to increases in fuel and operating costs, rising costs of financing capital construction and the cost of complying with U.S. federal and state regulations, among other factors.

Risk of Investing in Nuclear Companies (NUKZ). The Fund will be sensitive to, and its performance will depend to a greater extent on, the overall condition of nuclear companies. Nuclear companies may face considerable risk as a result of, among other risks, incidents and accidents, breaches of security, ill-intentioned acts of terrorism, air crashes, natural disasters (such as floods or earthquakes), equipment malfunctions or mishandling in storage, handling, transportation, treatment or conditioning of substances and nuclear materials. Such events could have serious consequences, especially in case of radioactive contamination and irradiation of the environment, for the general population, as well as a material, negative impact on a Fund’s portfolio companies and thus the Fund’s financial situation. In addition, nuclear companies are subject to competitive risk associated with the prices of other energy sources, such as natural gas and oil. Consumers of nuclear energy may have the ability to switch between nuclear energy and other energy sources and, as a result, during periods when competing energy sources are less expensive, the revenues of nuclear energy companies may decline with a corresponding impact on earnings.

Risk of Investing in Coal Companies (COAL). Companies involved in activities relating to the exploration for, mining of, and other related activities for coal face risks due to supply and demand variability. Weather conditions, a strong or weak domestic economy, the price levels of competing sources of fuel, political instability and conservation efforts may affect the demand for coal. The productivity of mining operations may be reduced by geological conditions, regulatory permits for mining activities and the availability of coal that meets standards set forth in the Clean Air Act, as amended in 1990. Companies involved in activities relating to the exploration for, mining of, and other related activities for coal are also impacted by the level and volatility of commodity prices, the exchange value of the dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources and mandated expenditures for safety and pollution control devices. In addition, companies in this industry may be significantly affected by the occurrence of certain events relating to international political and economic developments, the success of exploration projects and tax and other government regulations. A primary risk of the coal industry is the competitive risk associated with the prices of alternative fuels, such as natural gas and oil. For example, consumers of coal often have the ability to switch between the use of coal, oil or natural gas. As a result, during periods when competing fuels are less expensive, the revenues of companies in the coal industry may decline with a corresponding impact on earnings.

Market Risk. The market price of an investment could decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. The market value of an investment also may decline because of factors that affect a particular industry or industries such as labor shortages, increased production costs, and competitive conditions. Local, regional, or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the market generally and on specific investments. For example, in recent years, the COVID-19 pandemic, the large expansion of government deficits and debt as a result of government actions to mitigate the effects of the
