Investment Objective

The iShares FinTech Active ETF (the “Fund”) (formerly known as “BlackRock Future Financial and Technology ETF”) seeks to maximize total return.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. 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.

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 (ongoing expenses that you pay each year as a percentage of the value of your investments)
Management Fees1	Distribution and Service (12b-1) Fees	Other Expenses2	Total Annual Fund Operating Expenses	Fee Waiver1	Total Annual Fund Operating Expenses After Fee Waiver1
0.70%	None	0.00%	0.70%	(0.00)%	0.70%

¹  As described in the “Management” section of the Fund’s prospectus beginning on page 14, BFA has also contractually agreed to waive a portion of its management fees in an amount equal to the aggregate Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other equity and fixed-income mutual funds and exchange-traded funds (“ETFs”) advised by BFA or its affiliates through June 30, 2026. As described in the “Management” section of the Fund’s prospectus beginning on page 14, BFA has contractually agreed to waive a portion of its management fees in an amount equal to the aggregate Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in money market funds managed by BFA or its affiliates through June 30, 2026. The agreement (with respect to either waiver) may be terminated upon 90 days’ notice by a majority of the non-interested trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund.

²  The amount rounded to 0.00%.

S-1

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. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year	3 Years	5 Years	10 Years
$72	$224	$390	$871

Portfolio Turnover. 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 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 July 31, 2024, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of fintech companies and derivatives that provide investment exposure to such securities or to one or more market risk factors associated with such securities. The fintech companies in which the Fund intends to invest are financials and information technology companies that use technology to modify, enhance or automate financial services for businesses or

consumers. These companies are involved in activities that include, but are not limited to, the following: transaction and payment processing services, consumer finance, banking, insurance, financial exchanges and data, specialized finance, IT services, software, financial services, and capital markets. The Fund does not intend to invest directly in digital assets (including bitcoin and ether) or in pooled investment vehicles that seek to track the price performance of such digital assets. However, the Fund may invest in companies involved in the development and/or use of blockchain technologies, including companies that provide technology or services which support a digital exchange or payment network (such as banks, payment service providers, or other financial services companies) or hold cryptocurrency assets on their balance sheet (including publicly traded operating companies in unrelated industries). The Fund may invest in both newer and/or smaller companies and more established and/or larger companies in the financials and technology industries that use or provide financial services

S-2

technologies, including innovative or emerging technologies.

The Fund will concentrate its investments (i.e., invest at least 25% of its total assets) in the financials and technology groups of industries, in aggregate. Because this concentration is measured in aggregate across both groups of industries, at a given time the Fund may have less than 25% of its total assets invested in either the financials or the technology groups of industries.

Equity securities in which the Fund may invest include U.S. exchange-listed common stocks, exchange-traded preferred stocks and exchange-traded as well as unlisted American Depositary Receipts (“ADRs”). The Fund invests in ADRs to obtain exposure to foreign securities. ADRs are receipts typically issued by an American bank or trust company that evidence underlying securities issued by a foreign corporation.

The Fund may invest in companies of any market capitalization located anywhere in the world, including companies located in emerging markets.

The Fund may buy or sell U.S. exchange-traded futures on a security or an index of securities. A future is an agreement to buy or sell a security or an index of securities at a specific price on a specific date. The Fund may use futures to seek to increase the return of the Fund, to

hedge (or protect) the value of its assets against adverse movements in the securities markets, and to manage cash flows into or out of the Fund.

The Fund is classified as non-diversified under the Investment Company Act of 1940, as amended.

Summary of Principal Risks

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. The Fund is subject to certain risks, including the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective. Unlike many exchange-traded funds (“ETFs”), the Fund is not an index-based ETF. Certain key risks are prioritized below (with others following in alphabetical order), but the relative significance of any risk is difficult to predict and may change over time. You should review each risk factor carefully.

Fintech Risk. Fintech companies could result in new business models, applications, processes or products with an associated effect on the provision of financial services. Certain fintech companies may seek to disrupt or displace established financial institutions and may face competition from larger and more established companies. Fintech companies that utilize

S-3

disruptive technologies may not be able to capitalize on them when facing political and/or legal attacks from competitors, industry groups or local and national governments. Newer or smaller fintech companies may not currently be profitable, and there can be no assurance that these companies will be profitable in the future. Additionally, fintech companies may be adversely impacted by potential rapid product obsolescence, cybersecurity attacks and disruptions in the technology they depend on.

Legal and regulatory changes, particularly related to information privacy and data protection, may impact the products or services of fintech companies. Laws and regulations typically vary by state and by country, which may create challenges for smaller fintech companies to achieve scale. Increasing regulatory scrutiny and legal liability may limit the development and impede the growth of these companies. Similarly, the collection and storage of data from consumers and other sources may face increased scrutiny as regulators consider how data may be collected, stored, safeguarded and used.

Fintech companies that actively engage in blockchain technology are subject to risks that blockchain technology may not be widely adopted or may never develop optimized transactional processes that lead to realized economic returns for the fintech companies.

Furthermore, a lack of regulation on digital commodities and the associated platforms and lack of liquid markets for digital assets, as well as the highly speculative and volatile nature of many digital assets, may also adversely impact an investment in the Fund. Future regulatory developments may impact the Fund’s ability to invest or remain invested in digital asset-based businesses.

Financials Sector Risk. The performance of companies in the financials sector, as traditionally defined, may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, and interest rates, credit rating downgrades, adverse public perception, exposure concentration and decreased liquidity in credit markets. The impact of changes in regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. Cybersecurity incidents and technology malfunctions and failures have become increasingly frequent and have caused significant losses to companies in this sector, which may negatively impact the Fund.

Information Technology Sector Risk. IT companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights. Companies in the IT sector may

S-4

face increased government and regulatory scrutiny and may be subject to adverse government or regulatory action. Companies in the software industry may be adversely affected by, among other things, the decline or fluctuation of subscription renewal rates for their products and services and actual or perceived vulnerabilities in their products or services.

Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Asset Class Risk. Securities and other assets or financial instruments in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

Assets Under Management (AUM) Risk. From time to time, an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus), a third-party investor, BFA or an affiliate of BFA, or a fund may invest in the Fund and hold its investment for a specific period of time in order to facilitate commencement of the Fund’s operations or to allow the

Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels, which could negatively impact the Fund.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for exchange-traded funds (“ETFs”), such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the

S-5

market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund, BFA, the distributor, and other service providers (including the benchmark provider), market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Depositary Receipts Risk. The Fund will invest in stocks of foreign corporations. The Fund’s investment in such stocks will be in the form of ADRs. While the use of ADRs, which are traded on exchanges and represent an ownership in a foreign security, provides an alternative to directly purchasing the underlying

foreign securities in their respective markets and currencies, investments in ADRs continue to be subject to many of the risks associated with investing directly in foreign securities, including political, economic, and currency risk.

Derivatives Risk. The Fund may invest in certain types of derivative contracts, including futures, which can be more sensitive to changes in interest rates or to sudden fluctuations in market prices than conventional securities, which can result in greater losses to the Fund.

Futures Contract Risk. Futures are standardized, exchange-traded contracts that obligate a purchaser to take delivery, and a seller to make delivery, of a specific amount of an asset at a specified future date at a specified price. Unlike equities, which typically entitle the holder to a continuing ownership stake in an issuer, futures contracts normally specify a certain date for settlement in cash based on the level of the reference rate. The primary risks associated with the use of futures contracts are: (i) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (ii) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (iii) losses caused by unanticipated market movements, which are potentially unlimited; (iv) BFA’s inability to predict correctly the direction of prices and

S-6

other economic factors; and (v) the possibility that the counterparty will default in the performance of its obligations.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading of its portfolio securities. High portfolio turnover (considered by the Fund to mean higher than 100% annually) 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, as well as possible increased taxable distributions.

Infectious Illness Risk. An outbreak of an infectious respiratory illness, COVID-19, caused by a novel coronavirus developed into a global pandemic that has resulted in travel restrictions, disruption of healthcare systems, prolonged quarantines, cancellations, supply chain disruptions, lower consumer demand, layoffs, ratings downgrades, defaults and other significant economic impacts. Certain markets have experienced temporary closures, extreme volatility, severe losses, reduced liquidity and increased trading costs. Although vaccines have been developed and approved for use by various governments, the duration of the pandemic and its effects cannot be predicted with certainty. These events will have an impact on the Fund and its investments and could impact the Fund’s ability to

purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund’s NAV. Other infectious illness outbreaks in the future may result in similar impacts.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund may be adversely affected if an issuer of underlying securities held by the Fund is unable or unwilling to repay principal or interest when due. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Management Risk. The Fund is subject to management risk, which is the risk that the investment process, techniques and analyses applied by BFA will not produce the desired results, and those securities or other financial instruments

S-7

selected by BFA may result in returns that are inconsistent with the Fund’s investment objective. In addition, legislative, regulatory, or tax developments may affect the investment techniques available to BFA in connection with managing the Fund and may also adversely affect the ability of the Fund to achieve its investment objective.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues like pandemics or epidemics, recessions, the prospect or occurrence of a sovereign default or other financial crisis, or other events could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s NAV.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. Unlike some ETFs that track specific indexes, the Fund does not seek to replicate the performance of a specified index. Index-based ETFs have generally traded at prices that closely correspond to NAV per share. Given

the high level of transparency of the Fund’s holdings, BFA believes that the trading experience of the Fund should be similar to that of index-based ETFs. However, ETFs that do not seek to replicate the performance of a specified index have a limited trading history and, therefore, there can be no assurance as to whether, and/or the extent to which, the Fund’s shares will trade at premiums or discounts to NAV. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments. In addition, the securities of mid-capitalization companies may be more volatile and less liquid than those of large-capitalization companies.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that, compared with other funds that are classified as “diversified,” the Fund may invest a greater percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

S-8

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting issuers of non-U.S. securities or non-U.S. markets. In addition, non-U.S. securities markets may trade a small number of securities and may be unable to respond effectively to changes in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times.

Preferred Stock Risk. Preferred stocks are subject not only to issuer-specific and market risks generally applicable to equity securities, but also risks associated with fixed-income securities, such as interest rate risk. A company’s preferred stock, which may pay fixed or variable rates of return, generally pays dividends only after the company makes required payments to creditors, including vendors, depositors, counterparties, holders of its bonds and other fixed-income securities. As a result, the value of a company’s preferred stock will react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred stock may be less liquid than many other types of securities, such as common stock, and generally has limited or no voting rights. In addition, preferred stock is subject to the

risks that a company may defer or not pay dividends, and, in certain situations, may call or redeem its preferred stock or convert it to common stock. An issuer may decide to call its outstanding preferred stock in various environments based on its assessment of the relative cost of capital across the company’s capital structure. A market-wide increase in preferred stock being called may reduce the aggregate size of the preferred stock universe and the number of issuers with preferred stock outstanding. Such reductions may make it more challenging for the Fund to invest in the component securities of the Underlying Index, increasing the risk of the Fund being underinvested in the Underlying Index and thus increasing the risk of tracking error. To the extent that the Fund invests a substantial portion of its assets in convertible preferred stocks, declining common stock values may also cause the value of the Fund’s investments to decline.

Risk of Investing in the United States. 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.

Small-Capitalization Companies Risk. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments. In addition, the securities of small-capitalization

S-9

companies may be more volatile and less liquid than those of mid- and large-capitalization companies.

Small Fund Risk. When the Fund’s size is small, the Fund may experience low trading volume and wide bid/ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange. Any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Tax Risk. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and

taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. The tax treatment of certain derivatives is unsettled and may be subject to future legislation, regulation or administrative pronouncements issued by the U.S. Internal Revenue Service (“IRS”).

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund by showing how the Fund’s average annual returns for 1 year and since inception compare with MSCI ACWI Index. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

Calendar Year by Year Returns¹

¹  The Fund’s year-to-date return as of September 30, 2024 was 9.14%.

The best calendar quarter return during the period shown above was 14.15% in the 4th quarter of 2023; the worst was -7.67% in the 1st quarter of 2023.

¹  After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sales of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sales of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

²  The MSCI ACWI captures large- and mid-cap representation across 23 Developed Markets (DM) and 24 Emerging Markets (EM) countries. The index covers approximately 85% of the global investable equity opportunity set.

S-12

Management

Investment Adviser and Sub-Adviser. The Fund’s investment adviser is BFA. The Fund’s sub-adviser is BlackRock International Limited (“BIL” or the “Sub-Adviser”).

Portfolio Managers. Vasco Moreno and Hashim Bhattee (the “Portfolio Managers”) are jointly and primarily responsible for the day-to-day management of the Fund. Mr. Moreno has been Portfolio Manager of the Fund since August 2022. Mr. Bhattee has been Portfolio Manager of the Fund since July 2024.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund may only be bought and sold in the secondary market through a broker-dealer. Because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”).

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”), in which case, your distributions generally will be taxed when withdrawn.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. 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.
