INNOVATION AND TECH ACTIVE ETF Ticker: BAI       Stock Exchange: NYSE ARCA Investment Objective <div style="margin-top: 4pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">The iShares A.I. Innovation and Tech Active ETF (the “Fund”) seeks to maximize total return.</div> Fees and Expenses <div style="margin-top: 4pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. Amounts in the table are rounded to the nearest basis point, which in some cases may be “0.00.” The investment advisory agreement between BlackRock ETF Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except: (i) the management fees, (ii) interest expenses, (iii) taxes, (iv) expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, (v) distribution fees or expenses, and (vi) litigation expenses and any extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund’s pro rata share of the fees and expenses incurred indirectly by the Fund as a result of investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">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.</div> Annual Fund Operating Expenses(ongoing expenses that you pay each year as apercentage of the value of your investments) 0.0065 0 0.0000 0.0065 -0.0010 0.0055 June 30, 2028 Example.  This Example is intended to help you compare the cost of owning shares of 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 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. <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">Although your actual costs may be higher or lower, based on these assumptions, your costs would be:</div> 58 200 354 802 Portfolio Turnover <div style="margin-top: 4pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">The Fund may pay 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</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. For the fiscal year ended April 30, 2026, the Fund’s portfolio turnover rate was 107% of the average value of its portfolio.</div> 1.07 Principal Investment Strategies <div style="margin-top: 4pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">Under normal market conditions, the Fund invests at least 80% of its net assets plus any borrowings for investment purposes in equity securities issued by U.S. and non‑U.S. artificial intelligence (“A.I.”) companies, technology companies and technology-related companies. Investments in derivatives are counted toward the Fund’s 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. Fund management focuses on A.I. innovation by seeking to invest in companies that, as determined by Fund management in its discretion, meet current or forecasted revenue or net income thresholds or are projected to be future market leaders in the enablement, development, utilization and/or deployment of A.I. technology or products or services that leverage A.I. technology. Fund management has developed a proprietary framework to map companies to one or more of the following interconnected layers of an A.I. stack: A.I. power; accelerated computing; cloud infrastructure; A.I. models; data; data tools/infrastructure software; A.I. applications; and A.I. services and solutions. Fund management’s investment process includes, but is not limited to, direct engagement with company management, examination of corporate strategies and vision, and development of proprietary forecasts modeling expected outcomes.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">Technology or technology-related companies may include companies operating in any industry including, but not limited to, software, IT consulting, IT services, interactive home entertainment, interactive media and services, networking equipment, telecom services, communications equipment, technology hardware, storage and peripherals, electrical equipment, electronic equipment, instruments and components, semiconductors and semiconductor equipment, consumer finance, and interactive media and services. Technology-related companies include those that, for example, are using technology to innovate or disrupt a different industry or are developing an application that is being used by a technology company.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">Because the Fund’s 80% policy is measured in aggregate across A.I., technology and technology-related companies, at a given time the Fund may have less than 80% of its net assets invested in either A.I. or technology or technology-related companies.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">BFA determines, in its discretion, whether a company is an A.I., technology or technology-related company.</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">The Fund may invest in companies of any market capitalization located anywhere in the world, including companies located in emerging markets. Equity securities in which the Fund may invest include common stocks, preferred stocks, warrants, depositary receipts, and equity interests in real estate investment trusts (“REITs”) and master limited partnerships (“MLPs”). The Fund may also purchase convertible securities. The Fund may invest in shares of companies through initial public offerings (“IPOs”).</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">The Fund may, when consistent with the Fund’s investment objective, buy or sell options or futures on a security or an index of securities and may buy options on a currency or a basket of currencies, or enter into foreign currency transactions, including swaps (including total return swaps, some of which may be known as contracts for difference) (collectively, commonly known as derivatives). An option is the right to buy or sell a security or an index of securities at a specific price on or before a specific date. A future is an agreement to buy or sell a security or an index of securities at a specific price on a specific date. A swap is an agreement whereby one party exchanges its right to receive or its obligation to pay one type of currency for another party’s obligation to pay or its right to receive another type of currency in the future or for a period of time. The Fund typically uses derivatives as a substitute for taking a position in the underlying asset and/or as part of a strategy designed to reduce exposure to other risks, such as currency risk. The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques. The Fund may not enter into derivative transactions that create economic leverage.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">The Fund may also use forward foreign currency exchange contracts (obligations to buy or sell a currency at a set rate in the future).</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">The Fund will concentrate its investments in companies operating in one or more industries within the technology group of industries. The Fund may not invest more than 20% of its net assets in the securities of a single issuer.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">The Fund may engage in active and frequent trading of portfolio securities to achieve its primary investment strategies.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">The Fund is classified as non‑diversified under the Investment Company Act of 1940, as amended (the ”Investment Company Act”).</div> <div style="margin-top: 4pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">Under normal market conditions, the Fund invests at least 80% of its net assets plus any borrowings for investment purposes in equity securities issued by U.S. and non‑U.S. artificial intelligence (“A.I.”) companies, technology companies and technology-related companies. Investments in derivatives are counted toward the Fund’s 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. Fund management focuses on A.I. innovation by seeking to invest in companies that, as determined by Fund management in its discretion, meet current or forecasted revenue or net income thresholds or are projected to be future market leaders in the enablement, development, utilization and/or deployment of A.I. technology or products or services that leverage A.I. technology. Fund management has developed a proprietary framework to map companies to one or more of the following interconnected layers of an A.I. stack: A.I. power; accelerated computing; cloud infrastructure; A.I. models; data; data tools/infrastructure software; A.I. applications; and A.I. services and solutions. Fund management’s investment process includes, but is not limited to, direct engagement with company management, examination of corporate strategies and vision, and development of proprietary forecasts modeling expected outcomes.</div> Under normal market conditions, the Fund invests at least 80% of its net assets plus any borrowings for investment purposes in equity securities issued by U.S. and non‑U.S. artificial intelligence (“A.I.”) companies, technology companies and technology-related companies. Investments in derivatives are counted toward the Fund’s 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Artificial Intelligence Technology Risk.</span></span> Artificial intelligence technology is generally highly reliant on the collection and analysis of large amounts of data, and it is not possible or practicable to incorporate all relevant data into the model that such artificial intelligence utilizes to operate. Certain data in such models will inevitably contain a degree of inaccuracy and error — potentially materially so — and could otherwise be inadequate or flawed, which would be likely to degrade the effectiveness of the artificial intelligence technology.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">Companies involved in, or exposed to, artificial intelligence-related businesses may have limited product lines, markets, financial resources or personnel. These companies face intense competition and potentially rapid product obsolescence, and many depend significantly on retaining and growing the consumer base of their respective products and services. Many of these companies are also reliant on the end‑user demand of products and services in various industries that may in part utilize artificial intelligence. Further, many companies involved in, or exposed to, artificial intelligence-related businesses may be substantially exposed to the market and business risks of other industries or sectors, and the Fund may be adversely affected by negative developments impacting those companies, industries or sectors. It can be difficult to accurately capture what qualifies as an A.I. company.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">A.I. technology could face increasing regulatory scrutiny in the future, which may limit the development of this technology and impede the growth of companies that develop and/or utilize this technology. Similarly, the collection of data from consumers and other sources could face increased scrutiny as regulators consider how the data is collected, stored, safeguarded and used. A.I. companies may face regulatory fines and penalties, including potential forced break‑ups, that could</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">hinder the ability of the companies to operate on an ongoing basis. Country, government, and/or region‑specific regulations or restrictions could have an impact on A.I. and big data companies.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Technology Companies Risk.</span></span> Technology companies and companies that rely heavily on technological advances may have limited product lines, markets, financial resources, supply chains and personnel. These companies typically face intense competition, potentially rapid product obsolescence and changes in product cycles and customer preferences. They may face unexpected risks and costs associated with technological developments, such as artificial intelligence and machine learning. Technology companies also depend heavily on intellectual property rights and may be adversely affected by the loss or impairment of those rights. Technology companies may face increased government scrutiny and may be subject to adverse government or legal action.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Equity Securities Risk.</span></span> Stock markets are volatile. The price of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Non‑Diversification Risk</span></span>. The Fund is a non‑diversified fund. Because the Fund may invest in securities of a smaller number of issuers, it may be more exposed to the risks associated with and developments affecting an individual issuer than a fund that invests more widely.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Authorized Participant Concentration Risk.</span></span> Only an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus) may engage in creation or redemption transactions directly with the Fund. There are a limited number of institutions that may act as Authorized Participants for the Fund, including on an agency basis on behalf of other market participants. No Authorized Participant is obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for the Fund and no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Biotechnology Industry Risk</span></span>. Companies in the biotechnology industry, as traditionally defined, face intense competition and potentially rapid product obsolescence. Biotechnology companies may be adversely affected by the loss or impairment of intellectual property rights or changes in government regulations.</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Concentration Risk</span></span>. The Fund’s strategy of concentrating in U.S. and non‑U.S. A.I. companies, technology companies and technology-related companies means that its performance will be closely tied to the performance of a particular market segment. The Fund’s concentration in these companies may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. A downturn in these companies would have a larger impact on the Fund than on a mutual fund that does not concentrate in such companies. At times, the performance of these companies will lag the performance of other industries or the broader market as a whole.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Convertible Securities Risk</span></span>. The market value of a convertible security performs like that of a regular debt security; that is, if market interest rates rise, the value of a convertible security usually falls. In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest, principal or dividends when due, and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risks that apply to the underlying common stock, including the potential for increased volatility in the price of the convertible security.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Depositary Receipts Risk.</span></span> Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. In addition to investment risks associated with the underlying issuer, depositary receipts expose the Fund to additional risks associated with the non‑uniform terms that apply to depositary receipt programs, credit exposure to the depository bank and to the sponsors and other parties with whom the depository bank establishes the programs, currency risk and the risk of an illiquid market for depositary receipts. The issuers of unsponsored depositary receipts are not obligated to disclose information that is, in the United States, considered material. Therefore, there may be less information available regarding these issuers and there may not be a correlation between such information and the market value of the depositary receipts. While depositary receipts provide an alternative to directly purchasing underlying foreign securities in their respective markets and currencies, they continue to be subject to many of the risks associated with investing directly in foreign securities, including political, economic, and currency risk.</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Derivatives Risk.</span></span> The Fund’s use of derivatives may increase its costs, reduce the Fund’s returns and/or increase volatility. Derivatives involve significant risks, including:</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-style: italic;">Leverage Risk </span>— The Fund’s use of derivatives can magnify the Fund’s gains and losses. Relatively small market movements may result in large changes in the value of a derivatives position and can result in losses that greatly exceed the amount originally invested.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-style: italic;">Market Risk</span> — Some derivatives are more sensitive to interest rate changes and market price fluctuations than other securities. The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, which losses are potentially unlimited. Finally, BFA may not be able to predict correctly the direction of securities prices, interest rates and other economic factors, which could cause the Fund’s derivatives positions to lose value.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-style: italic;">Counterparty Risk</span> — Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will be unable or unwilling to fulfill its contractual obligation, and the related risks of having concentrated exposure to such a counterparty.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-style: italic;">Illiquidity Risk</span> — The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-style: italic;">Operational Risk</span> — The use of derivatives includes the risk of potential operational issues, including documentation issues, settlement issues, systems failures, inadequate controls and human error.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-style: italic;">Legal Risk</span> — The risk of insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-style: italic;">Volatility and Correlation Risk</span> — Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate with the overall securities markets.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-style: italic;">Valuation Risk </span>— Valuation for derivatives may not be readily available in the market. Valuation may be more difficult in times of market turmoil since many</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">investors and market makers may be reluctant to purchase complex instruments or quote prices for them.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-style: italic;">Hedging Risk</span> — Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund’s hedging transactions will be effective. The use of hedging may result in certain adverse tax consequences.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-style: italic;">Tax Risk </span>— Certain aspects of the tax treatment of derivative instruments, including swap agreements and commodity-linked derivative instruments, are currently unclear and may be affected by changes in legislation, regulations or other legally binding authority. Such treatment may be less favorable than that given to a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Emerging Markets Risk</span></span>. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging financial markets have far lower trading volumes and less liquidity than developed markets.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Financial Services Industry Risk</span></span>. Because of its investments in the financial services industry, the Fund will be more susceptible to any economic, business, political or other developments which generally affect this industry sector. As a result, the Fund will be exposed to a large extent to the risks associated with that industry, such as government regulation, the availability and cost of capital funds (including the availability and stability of deposits in the case of deposit-taking institutions), consolidation and general economic conditions. Financial services companies are also exposed to losses if borrowers and other counterparties experience financial problems and/or cannot repay their obligations.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">When interest rates go up, the value of securities issued by many types of financial services companies generally goes down. In many countries, financial services and the companies that provide them are regulated by governmental entities, which can increase costs for new services or products and make it difficult to pass increased costs on to consumers. In certain areas, deregulation of financial</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">services companies has resulted in increased competition and reduced profitability for certain companies.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">The profitability of many types of financial services companies may be adversely affected in certain market cycles, including periods of rising interest rates, which may restrict the availability and increase the cost of capital, and declining economic conditions, which may cause credit losses due to financial difficulties of borrowers. Because many types of financial services companies are vulnerable to these economic cycles, the Fund’s investments may lose value during such periods.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Foreign Securities Risk</span></span>. Foreign investments often involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money. These risks include:</div> <table cellpadding="0" cellspacing="0" style="border-collapse: collapse; font-family: arial; font-size: 10pt; border-spacing: 0px; width: 100%;"> <tr style="page-break-inside: avoid;"> <td style="width: 19.5pt; vertical-align: top; text-align: left;">•</td> <td style="width: 0.75pt; vertical-align: top;"> </td> <td style="vertical-align: top; text-align: left;">The Fund generally holds its foreign securities and cash in foreign banks and securities depositories, which may be recently organized or new to the foreign custody business and may be subject to only limited or no regulatory oversight.</td> </tr> </table> <table cellpadding="0" cellspacing="0" style="border-collapse: collapse; font-family: arial; font-size: 10pt; border-spacing: 0px; width: 100%;"> <tr style="page-break-inside: avoid;"> <td style="width: 19.5pt; vertical-align: top; text-align: left;">•</td> <td style="width: 0.75pt; vertical-align: top;"> </td> <td style="vertical-align: top; text-align: left;">Changes in foreign currency exchange rates can affect the value of the Fund’s portfolio.</td> </tr> </table> <table cellpadding="0" cellspacing="0" style="border-collapse: collapse; font-family: arial; font-size: 10pt; border-spacing: 0px; width: 100%;"> <tr style="page-break-inside: avoid;"> <td style="width: 19.5pt; vertical-align: top; text-align: left;">•</td> <td style="width: 0.75pt; vertical-align: top;"> </td> <td style="vertical-align: top; text-align: left;">The economies of certain foreign markets may not compare favorably with the economy of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources and balance of payments position.</td> </tr> </table> <table cellpadding="0" cellspacing="0" style="border-collapse: collapse; font-family: arial; font-size: 10pt; border-spacing: 0px; width: 100%;"> <tr style="page-break-inside: avoid;"> <td style="width: 19.5pt; vertical-align: top; text-align: left;">•</td> <td style="width: 0.75pt; vertical-align: top;"> </td> <td style="vertical-align: top; text-align: left;">The governments of certain countries, or the U.S. Government with respect to certain countries, may prohibit or impose substantial restrictions through capital controls and/or sanctions on foreign investments in the capital markets or certain industries in those countries, which may prohibit or restrict the ability to own or transfer currency, securities, derivatives or other assets.</td> </tr> </table> <table cellpadding="0" cellspacing="0" style="border-collapse: collapse; font-family: arial; font-size: 10pt; border-spacing: 0px; width: 100%;"> <tr style="page-break-inside: avoid;"> <td style="width: 19.5pt; vertical-align: top; text-align: left;">•</td> <td style="width: 0.75pt; vertical-align: top;"> </td> <td style="vertical-align: top; text-align: left;">Many foreign governments do not supervise and regulate stock exchanges, brokers and the sale of securities to the same extent as does the United States and may not have laws to protect investors that are comparable to U.S. securities laws.</td> </tr> </table> <table cellpadding="0" cellspacing="0" style="border-collapse: collapse; font-family: arial; font-size: 10pt; border-spacing: 0px; width: 100%;"> <tr style="page-break-inside: avoid;"> <td style="width: 19.5pt; vertical-align: top; text-align: left;">•</td> <td style="width: 0.75pt; vertical-align: top;"> </td> <td style="vertical-align: top; text-align: left;">Settlement and clearance procedures in certain foreign markets may result in delays in payment for or delivery of securities not typically associated with settlement and clearance of U.S. investments.</td> </tr> </table> <table cellpadding="0" cellspacing="0" style="border-collapse: collapse; font-family: arial; font-size: 10pt; border-spacing: 0px; width: 100%;"> <tr style="page-break-inside: avoid;"> <td style="width: 19.5pt; vertical-align: top; text-align: left;">•</td> <td style="width: 0.75pt; vertical-align: top;"> </td> <td style="vertical-align: top; text-align: left;">The Fund’s claims to recover foreign withholding taxes may not be successful, and if the likelihood of recovery of foreign withholding taxes materially decreases, due to, for example, a change in tax regulation or approach in the foreign country, accruals in the Fund’s net asset value for such refunds may be written down partially or in full, which will adversely affect the Fund’s net asset value.</td> </tr> </table> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">High Portfolio Turnover Risk</span></span>. The Fund may engage in active and frequent trading of its portfolio securities. High portfolio turnover (more than 100%) may result in increased transaction costs to the Fund, including brokerage commissions, dealer mark‑ups and other transaction costs on the sale of the securities and on reinvestment in other securities. The sale of Fund portfolio securities may result in the realization and/or distribution to shareholders of higher capital gains or losses as compared to a fund with less active trading policies, such as index ETFs. These effects of higher than normal portfolio turnover may adversely affect Fund performance.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Industrials Sector Risk.</span></span> Companies in the industrials sector may be adversely affected by changes in the supply of and demand for products and services, product obsolescence, claims for environmental damage or product liability and changes in general economic conditions, among other factors.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Issuer Risk</span></span>. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Large Shareholder and Large-Scale Redemption Risk</span></span><span style="font-weight: bold;">. </span>Certain shareholders, including an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares, or may invest in the Fund and hold their investment for a limited period of time. There can be no assurance that any large shareholder or large group of shareholders would not redeem their investment.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">Redemptions of a large number of Fund shares could require the Fund to dispose of assets to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such tax year. In some circumstances, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. To the extent the Fund permits redemptions in cash, these large redemptions may also force the Fund to sell portfolio securities when it might not otherwise do so, which may negatively impact the Fund’s NAV, increase the Fund’s brokerage costs and/or have a material effect on the market price of the Fund shares.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Leverage Risk.</span></span> Some transactions may give rise to a form of economic leverage. These transactions may include, among others, derivatives, and may expose the Fund to greater risk and increase its costs. The use of leverage may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet the applicable requirements of the Investment Company Act, and the rules thereunder. Increases and decreases in the value of the Fund’s portfolio will be magnified when the Fund uses leverage.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Market Risk and Selection Risk.</span></span> Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. An investor could lose money over short periods due to fluctuation in the Fund’s net asset value in response to short-term market movements and over longer periods during market downturns. Securities or other investments held by the Fund may underperform the markets, the relevant indices or benchmarks, or the securities selected by other funds with similar investment objectives and investment strategies, or may otherwise fail to perform as intended. The value of a security or other asset may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or other asset, or factors that affect a particular issuer or issuers, exchange, country, group of countries, region, market, industry, group of industries, sector or asset class. The success of the Fund’s activities could be affected by interest rates, availability of credit, inflation rates, economic uncertainty, changes in laws, tariffs and trade barriers, supply chain disruptions, economic sanctions, currency exchange controls, and local, regional or global events such as war, acts of terrorism, natural and environmental disasters, the spread of infectious illness or other public health issues, recessions, or other events.</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">Recent policy initiatives undertaken by the U.S. government have the potential to impact international relations, trade agreements and the overall regulatory environment in ways that could create uncertainty and instability in domestic and global markets, and could adversely affect the investment performance of the Fund. In particular, actions taken by the U.S. government in respect of international trade relations could lead to trade wars, increased costs for imported goods, disruptions in supply chains, reduced foreign investment, and instability in regions where the Fund invests.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Market Trading Risk. </span></span>The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund shares.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Master Limited Partnerships Risk</span></span>. The common units of an MLP are listed and traded on U.S. securities exchanges and their value fluctuates predominantly based on prevailing market conditions and the success of the MLP. Unlike owners of common stock of a corporation, owners of common units have limited voting rights and have no ability to annually elect directors. In the event of liquidation, common units have preference over subordinated units, but not over debt or preferred units, to the remaining assets of the MLP.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">“New Issues” Risk</span></span>. “New issues” are IPOs of equity securities. Securities issued in IPOs have no trading history, and information about the companies may be available for very limited periods. In addition, the prices of securities sold in IPOs may be highly volatile or may decline shortly after the IPO.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Operational and Technology Risks.</span></span> The Fund is directly and indirectly susceptible to operational and technology risks, including those related to human errors, processing errors, communication errors, systems failures, cybersecurity incidents, and the use of artificial intelligence and machine learning (“AI”), which may result in losses for the Fund and its shareholders or may impair the Fund’s operations.</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">While the Fund’s service providers are required to have appropriate operational, information security and cybersecurity risk management policies and procedures, their methods of risk management may differ from those of the Fund. Operational and technology risks for the issuers in which the Fund invests could also result in material adverse consequences for such issuers and may cause the Fund’s investments in such issuers to lose value.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Preferred Securities Risk.</span></span> Preferred securities may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. In addition, a company’s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">REIT Investment Risk.</span></span> Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, may engage in dilutive offerings of securities and may be more volatile than other securities. REIT issuers may also fail to maintain their exemptions from investment company registration or fail to qualify for the “dividends paid deduction” under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), which allows REITs to reduce their corporate taxable income for dividends paid to their shareholders.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Risk of Investing in the United States</span></span>. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Small and Mid‑Capitalization Company Risk</span></span>. Companies with small or mid‑size market capitalizations will normally have more limited product lines, markets and financial resources and will be dependent upon a more limited management group than larger capitalized companies. In addition, it is more difficult to get information on smaller companies, which tend to be less well known, have shorter operating histories, do not have significant ownership by large investors and are followed by relatively few securities analysts.</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Telecommunications Risk.</span></span> The telecommunications industry is subject to governmental regulation and a greater price volatility than the overall market and the products and services of telecommunications companies may be subject to rapid obsolescence resulting from changing consumer tastes, intense competition, and strong market reactions to technological developments throughout the industry. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Tokyo Stock Exchange Issuer Limitation Risk</span></span>. Because the Fund is held by another fund that is listed on the Tokyo Stock Exchange, the Fund is required to limit its exposure to a single issuer to less than 20% of the Fund’s net assets. In the event of a breach, the Fund is required to reduce the position to below 20% of net assets within one month. If the Fund is required to undertake such a sale, it could have adverse tax consequences for the Fund or impact Fund performance.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Valuation Risk</span></span>. The price that the Fund could receive upon the sale (or other disposition) of a security or other asset may differ from the Fund’s valuation of the security or other asset, particularly</div> <div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when investors are not able to purchase or sell Fund shares.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">Authorized Participants that create or redeem Fund shares on days when the Fund is holding fair-valued securities or other assets may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the securities or other assets not been fair valued or been valued using a different methodology. The ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.</div> <div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;"><span style="font-weight: bold;"><span style="font-style: italic;">Warrants Risk</span></span>. If the price of the underlying stock does not rise above the exercise price before the warrant expires, the warrant generally expires without any value and the Fund will lose any amount it paid for the warrant. Thus, investments in warrants may involve substantially more risk than investments in common stock. Warrants may trade in the same markets as their underlying stock; however, the price of the warrant does not necessarily move with the price of the underlying stock.</div> Performance Information <div style="margin-top: 4pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial;">The information shows you how the Fund’s performance has varied year by year and provides some indication of the risks of investing in the Fund.

Morningstar Global Artificial Intelligence Select Index (Net) is designed to deliver unparalleled, thematically pure exposure to companies involved with artificial intelligence (AI) technologies by drawing on the in-depth knowledge and forward-looking insights of Morningstar’s equity research team. It targets stocks with exposure to generative AI, AI data & infrastructure, AI software, and AI services. Returns for net indices generally assume the reinvestment of dividends after the deduction of the maximum withholding tax in each country applicable to non-residents of the country as determined by the index provider. Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund’s applicable withholding tax rates, if any. For additional comparative performance information for the Morningstar Global Artificial Intelligence Select Index, please see the Fund’s Statement of Additional Information. As described in the “Management” section of the Fund’s prospectus beginning on page 16, BFA has contractually agreed to waive 0.10% of its management fee payable through June 30, 2028.
