The Markets in Review

Dear Shareholder,

Investment performance in the 12 months ended July 31, 2019 was a tale of two markets. The first half of the reporting period was characterized by restrictive monetary policy, deteriorating economic growth, equity market volatility, and rising fear of an imminent recession. During the second half of the reporting period, stocks and bonds rebounded sharply, as restrained inflation and weak economic growth led the U.S. Federal Reserve (the “Fed”) to stop raising interest rates, which led to broad-based optimism that stimulative monetary policy could help forestall a recession.

After the dust settled, the U.S. equity and bond markets posted mixed returns while weathering significant volatility. Less volatile U.S. large cap equities and U.S. bonds advanced, while equities at the high end of the risk spectrum — emerging markets, international developed, and U.S. small cap — posted relatively flat returns.

Fixed-income securities delivered modest positive returns with relatively low volatility, as interest rates declined (and bond prices rose). Longer-term U.S. Treasury yields declined further than short-term Treasury yields. This led to positive returns for U.S. Treasuries and a substantial flattening of the yield curve. Investment grade and high yield corporate bonds also posted positive returns, as the credit fundamentals in corporate markets remained relatively solid.

In the U.S. equity market, volatility spiked in late 2018, as a wide range of risks were brought to bear on markets, ranging from rising interest rates and slowing global growth to heightened trade tensions and political turmoil. These risks manifested in a broad-based sell-off in December, leading to the worst December performance on record since 1931.

Volatility also rose in emerging markets, as the rising U.S. dollar and higher interest rates in the U.S. disrupted economic growth abroad. U.S.-China trade relations and debt concerns adversely affected the Chinese stock market, particularly in mainland China, while Turkey and Argentina became embroiled in currency crises, largely due to hyperinflation in both countries. An economic slowdown in Europe and ongoing uncertainty about Brexit led to modest performance for European equities.

As equity performance faltered and global economic growth slowed, the Fed shifted to a more patient perspective on the economy in January 2019. The Fed left interest rates unchanged for six months, then lowered interest rates for the first time in 11 years in July 2019. Similarly, the European Central Bank signaled a continuation of accommodative monetary policy, while China committed to looser credit conditions and an increase in fiscal spending.

The outpouring of global economic stimulus led to a sharp rally in risk assets throughout the world. Hopes continued to remain high thereafter, as the current economic expansion became the longest in U.S. history. Looking ahead, markets are pricing in additional rate cuts by the Fed over the next year, as investors anticipate a steady shift toward more stimulative monetary policy.

We expect a slowing expansion with additional room to run, as opposed to an economic recession. However, escalating trade tensions and the resulting disruptions in global supply chains have become the greatest risk to the global expansion.

We believe U.S. and emerging market equities remain relatively attractive. Within U.S. equities, companies with high-quality earnings and strong balance sheets offer the most attractive risk/reward trade-off. For bonds, U.S. Treasuries are likely to help buffer against volatility in risk assets, while income from other types of bonds can continue to offer steady returns.

In this environment, investors need to think globally, extend their scope across a broad array of asset classes, and be nimble as market conditions change. We encourage you to talk with your financial advisor and visit blackrock.com for further insight about investing in today’s markets.

About Fund Performance

Past performance is no guarantee of future results. Current performance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at www.blackrock.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. The investment return and principal value of shares will vary with changes in market conditions. Shares may be worth more or less than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees. Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint between the highest bid and the lowest ask on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Since shares of a fund may not trade in the secondary market until after the fund’s inception, for the period from inception to the first day of secondary market trading in shares of the fund, the NAV of the fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV, respectively.

Shareholder Expenses

As a shareholder of your Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of fund shares and (2) ongoing costs, including management fees and other fund expenses. The expense example, which is based on an investment of $1,000 invested at the beginning of the period (or from the commencement of operations if less than 6 months) and held through the end of the period, is intended to help you understand your ongoing costs (in dollars and cents) of investing in your Fund and to compare these costs with the ongoing costs of investing in other funds.

Actual Expenses — The table provides information about actual account values and actual expenses. Annualized expense ratios reflect contractual and voluntary fee waivers, if any. To estimate the expenses that you paid on your account over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During the Period.”

Hypothetical Example for Comparison Purposes — The table also provides information about hypothetical account values and hypothetical expenses based on your Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. You may use this information to compare the ongoing costs of investing in your Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as brokerage commissions paid on purchases and sales of fund shares. Therefore, the hypothetical examples are useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Notes to Financial Statements

1.	ORGANIZATION

BlackRock ETF Trust (“BlackRock ETF” or, the “Trust”) was organized as a Delaware statutory trust on October 31, 2018 and is authorized to have multiple series or portfolios. The Trust is an open-end management investment company registered with the U.S. Securities and Exchange Commission (the “SEC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). As of July 31, 2019, BlackRock U.S. Equity Factor Rotation ETF is the only investment series or portfolio of the Trust.

These financial statements relate only to the following fund (“U.S. Equity Factor Rotation” or, the “Fund”):


BlackRock ETF	Diversification Classification
U.S. Equity Factor Rotation^(a)		Non-diversified

^(a)

The Fund commenced operations on March 19, 2019.

The Fund, together with certain other registered investment companies advised by BlackRock Fund Advisors (“BFA” or the “Manager”) or its affiliates, is included in a complex of equity, multi-asset, index and money market funds referred to as the BlackRock Multi-Asset Complex.

2.	SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by the Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

Investment Transactions and Income Recognition: Investment transactions are accounted for on trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Dividend income and capital gain distributions, if any, are recognized on the ex-dividend date, net of any foreign taxes withheld at source. Any taxes withheld that are reclaimable from foreign tax authorities are reflected in tax reclaims receivable. Distributions received by the Fund may include a return of capital that is estimated by management. Such amounts are recorded as a reduction of the cost of investments or reclassified to capital gains. Upon notification from issuers, some of the dividend income received from a real estate investment trust may be re-designated as a return of capital or capital gain. Non-cash dividends, if any, are recognized on the ex-dividend date and recorded as non-cash dividend income at fair value. Interest income is accrued daily.

Foreign Taxes: The Fund may be subject to foreign taxes (a portion of which may be reclaimable) on income, stock dividends, capital gains on investments, or certain foreign currency transactions. All foreign taxes are recorded in accordance with the applicable foreign tax regulations and rates that exist in the foreign jurisdictions in which the Fund invests. These foreign taxes, if any, are paid by the Fund and are reflected in its statement of operations as follows: foreign taxes withheld at source are presented as a reduction of income, foreign taxes on securities lending income are presented as a reduction of securities lending income, foreign taxes on stock dividends are presented as “other foreign taxes”, and foreign taxes on capital gains from sales of investments and foreign taxes on foreign currency transactions are included in their respective net realized gain (loss) categories. Foreign taxes payable or deferred as of July 31, 2019, if any, are disclosed in the statement of assets and liabilities.

In-kind Redemptions: For financial reporting purposes, in-kind redemptions are treated as sales of securities resulting in realized capital gains or losses to the Fund. Because such gains or losses are not taxable to the Fund and are not distributed to existing Fund shareholders, the gains or losses are reclassified from accumulated net realized gain (loss) to paid-in capital at the end of the Fund’s tax year. These reclassifications have no effect on net assets or net asset value per share.

Distributions: Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Fund.

Indemnifications: In the normal course of business, the Fund enters into contracts that contain a variety of representations that provide general indemnification. The Fund’s maximum exposure under these arrangements is unknown because it involves future potential claims against the Fund, which cannot be predicted with any certainty.

3.	INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS

Investment Valuation Policies: The Fund’s investments are valued at fair value (also referred to as “market value” within the financial statements) each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. A fund determines the fair value of its financial instruments using various independent dealers or pricing services under policies approved by the Board of Trustees of the Trust (the “Board”). The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) is the committee formed by management to develop global pricing policies and procedures and to oversee the pricing function for all financial instruments.

Fair Value Inputs and Methodologies: The following methods and inputs are used to establish the fair value of the Fund’s assets and liabilities:

•

Equity investments traded on a recognized securities exchange are valued at that day’s last traded price or official closing price, as applicable, on the exchange where the stock is primarily traded. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last traded price.


N O T E S T O F I N A N C I A L S T A T E M E N T S			17

Notes to Financial Statements (continued)

•

Investments in open-end U.S. mutual funds (including money market funds) are valued at that day’s published net asset value (“NAV”).

If events (e.g., a company announcement, market volatility or a natural disaster) occur that are expected to materially affect the value of an investment, or in the event that application of these methods of valuation results in a price for an investment that is deemed not to be representative of the market value of such investment, or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with policies approved by the Board as reflecting fair value (“Fair Valued Investments”). The fair valuation approaches that may be used by the Global Valuation Committee include market approach, income approach and the cost approach. Valuation techniques used under these approaches take into consideration inputs that include but are not limited to (i) attributes specific to the investment; (ii) the principal market for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, if reasonably available; (v) quoted prices for similar investments in active markets; and (vi) other inputs, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates.

Fair Value Hierarchy: Various inputs are used in determining the fair value of financial instruments. These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows:

•

Level 1 — Unadjusted price quotations in active markets for identical assets or liabilities;

•

Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

•

Level 3 — Unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available, (including the Global Valuation Committee’s assumptions used in determining the fair value of financial instruments).

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its schedule of investments. The categorization of a value determined for financial instruments is based on the pricing transparency of the financial instruments and is not necessarily an indication of the risks associated with investing in those securities.

4.	SECURITIES AND OTHER INVESTMENTS

Securities Lending: The Fund may lend its securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by an approved bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by the Fund is required to have a value of at least 102% of the current market value of the loaned securities for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securities on loan. The market value of the loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fund or excess collateral is returned by the Fund, on the next business day. During the term of the loan, the Fund is entitled to all distributions made on or in respect of the loaned securities but does not receive interest income on securities received as collateral. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

As of July 31, 2019, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA, the Fund’s investment adviser, or its affiliates and is disclosed in the schedule of investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan for the Fund, if any, are also disclosed in its schedule of investments. The market value of any securities on loan as of July 31, 2019 and the value of the related cash collateral are disclosed in the statement of assets and liabilities.

Securities lending transactions are entered into by a fund under Master Securities Lending Agreements (each, an “MSLA”) which provide the right, in the event of default (including bankruptcy or insolvency) for the non-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, the fund, as lender, would offset the market value of the collateral received against the market value of the securities loaned. The value of the collateral is typically greater than the market value of the securities loaned, leaving the lender with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, absent an event of default, the borrower can resell or re-pledge the loaned securities, and the fund can reinvest cash collateral received in connection with loaned securities.

Notes to Financial Statements (continued)

The following table is a summary of the securities lending agreements by counterparty which are subject to offset under an MSLA as of July 31, 2019:


	Market Value of		Cash Collateral			Non-Cash Collateral
BlackRock ETF and Counterparty		Securities on Loan		Received	^(a)		Received		Net Amount

BofA Securities, Inc.		242		242			—		—
Citigroup Global Markets Inc.		12,460		12,460			—		—
Credit Suisse AG Dublin Branch		211		211			—		—

	$	16,876	$	16,876		$	—	$	—

^(a)

Collateral received in excess of the market value of securities on loan is not presented in this table. The total cash collateral received by the Fund is disclosed in the Fund’s statement of assets and liabilities.

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Fund benefits from a borrower default indemnity provided by BlackRock, Inc. (“BlackRock”). BlackRock’s indemnity allows for full replacement of the securities loaned to the extent the collateral received does not cover the value of the securities loaned in the event of borrower default. The Fund could incur a loss if the value of an investment purchased with cash collateral falls below the market value of the loaned securities or if the value of an investment purchased with cash collateral falls below the value of the original cash collateral received. Such losses are borne entirely by the Fund.

5.	INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Advisory Fees: Pursuant to an Investment Advisory Agreement with the Trust, BFA manages the investment of the Fund’s assets. BFA is a California corporation indirectly owned by BlackRock.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and extraordinary expenses (as determined by a majority of the Trustees who are not “interested persons” of the Trust).

For its investment advisory services to the Fund, BFA will be paid a management fee from the Fund based on a percentage of the Fund’s average daily net assets as follows:


Average Daily Net Assets	Investment Advisory Fee
First $1 billion		0.30	%
Over $1 billion, up to and including $3 billion		0.28
Over $3 billion, up to and including $5 billion		0.27
Over $5 billion, up to and including $10 billion		0.26
Over $10 billion		0.25

Expense Waivers: BFA has voluntarily agreed to waive its management fee payable by the Fund to limit the annual management fee paid by the Fund to 0.20%. BFA may also from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

For the year ended July 31, 2019, BFA voluntarily waived its investment advisory fee for the Fund in the amount of $7,565.

Distributor: BlackRock Investments, LLC, an affiliate of BFA, is the distributor for the Fund. Pursuant to the distribution agreement, BFA is responsible for any fees or expenses for distribution services provided to the Fund.

Securities Lending: The SEC has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Fund, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to securities lending.

The Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan (the “collateral investment fees”). The cash collateral is invested in a money market fund managed by BFA or its affiliates. However, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees the Fund bears to an annual rate of 0.04%. The shares of such money market fund will not be subject to a sales load, distribution fee or service fee. The money market fund in which the cash collateral has been invested may, under certain circumstances, impose a liquidity fee of up to 2% of the value redeemed or temporarily restrict redemptions for up to 10 business days during a 90 day period, in the event that the money market fund’s weekly liquid assets fall below certain thresholds.

Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Fund retains a portion of securities lending income and remits a remaining portion to BTC as compensation for its services as securities lending agent.


N O T E S T O F I N A N C I A L S T A T E M E N T S			19

Notes to Financial Statements (continued)

Pursuant to the current securities lending agreement, the Fund retains 73.5% of securities lending income (which excludes collateral investment fees) and this amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees earned across the BlackRock Multi-Asset Complex in a calendar year exceeds a specified threshold, the Fund, pursuant to the securities lending agreement, will retain for the remainder of that calendar year securities lending income in an amount equal to 80% of securities lending income (which excludes collateral investment fees), and this amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

7.	INCOME TAX INFORMATION

The Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of the Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

Management has analyzed tax laws and regulations and their application to the Fund as of July 31, 2019, inclusive of the open tax return years, and does not believe that there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

The tax character of distributions paid was as follows:

8.	PRINCIPAL RISKS

In the normal course of business, the Fund invests in securities or other instruments and may enter into certain transactions, and such activities subject the Fund to various risks, including, among others, fluctuations in the market (market risk) or failure of an issuer to meet all of its obligations. The value of securities or other instruments may also be affected by various factors, including, without limitation: (i) the general economy; (ii) the overall market as well as local, regional or global political and/or social instability; (iii) regulation, taxation or international tax treaties between various countries; or (iv) currency, interest rate or price fluctuations. The Fund’s prospectus provides details of the risks to which the Fund is subject.

Market Risk: Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by its investment in underlying funds. The fair value of securities held by a fund may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’s schedule of investments.

Credit Risk: Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

Concentration Risk: A diversified portfolio, where this is appropriate and consistent with a fund’s objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within the Fund’s portfolio are disclosed in its schedule of investments.

When a fund concentrates its investments in securities within a single or limited number of market sectors, it assumes the risk that economic, regulatory, political and social conditions affecting such sectors may have a significant impact on the fund and could affect the income from, or the value or liquidity of, the fund’s portfolio.

9.	CAPITAL SHARE TRANSACTIONS

Capital shares are issued and redeemed by the Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of the Fund are not redeemable.

Transactions in capital shares were as follows:



	Period Ended
	07/31/19

BlackRock ETF	Shares		Amount

U.S. Equity Factor Rotation
Shares sold		800,000	$	20,000,000

The consideration for the purchase of Creation Units of the Fund generally consists of the in-kind deposit of a designated portfolio of securities and a specified amount of cash. The Fund may be offered in Creation Units solely or partially for cash in U.S. dollars. Investors purchasing and redeeming Creation Units may pay a purchase transaction fee and a redemption transaction fee directly to State Street Bank and Trust Company, the Trust’s administrator, to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units, including Creation Units for cash. Investors transacting in Creation Units for cash may also pay an additional variable charge to compensate the Fund for certain transaction costs (i.e., stamp taxes, taxes on currency or other financial transactions, and brokerage costs) and market impact expenses relating to investing in portfolio securities. Such variable charges, if any, are included in shares sold in the table above.

From time to time, settlement of securities related to in-kind contributions or in-kind redemptions may be delayed. In such cases, securities related to in-kind transactions are reflected as a receivable or a payable in the statement of assets and liabilities.

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of BlackRock U.S. Equity Factor Rotation ETF (the “Fund”) as of July 31, 2019, and the related statements of operations and changes in net assets, including the related notes, and the financial highlights for the period March 19, 2019 (commencement of operations) through July 31, 2019 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of July 31, 2019, and the results of its operations, changes in net assets, and the financial highlights for the period March 19, 2019 (commencement of operations) through July 31, 2019 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks.

Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of July 31, 2019 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures.

Board Review and Approval of Investment Advisory Contract

BlackRock ETF Trust

The Board of Trustees (the “Board,” the members of which are referred to as “Board Members”) of BlackRock ETF Trust (the “Trust”) met in person on February 20-21, 2019 (the “Organizational Meeting”) to consider the approval of the proposed investment advisory agreement (the “Agreement”) between the Trust, on behalf of BlackRock U.S. Equity Factor Rotation ETF (the “Fund”), a series of the Trust, and BlackRock Fund Advisors (the “Manager” or “BlackRock”), the Trust’s investment advisor.

Activities and Composition of the Board

On the date of the Organizational Meeting, the Board consisted of fifteen individuals, thirteen of whom were not “interested persons” of the Trust as defined in the Investment Company Act of 1940, as amended (the “1940 Act”) (the “Independent Board Members”). The Board Members are responsible for the oversight of the operations of the Trust and perform the various duties imposed on the directors of investment companies by the 1940 Act. The Independent Board Members have retained independent legal counsel to assist them in connection with their duties. The Chair of the Board is an Independent Board Member. The Board has established five standing committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight Committee and an Ad Hoc Topics Committee, each of which is chaired by an Independent Board Member and composed of Independent Board Members (except for the Ad Hoc Topics Committee, which also has one interested Board Member).

The Agreement

Consistent with the requirements of the 1940 Act, the Board is required to consider the initial approval of the Agreement. In connection with this deliberative process, the Board assessed, among other things, the nature, extent and quality of the services to be provided to the Fund by BlackRock, BlackRock’s personnel and affiliates, including (as applicable): investment management; accounting, administrative and shareholder services; oversight of the Fund’s service providers; risk management and oversight; legal and compliance services; and ability to meet applicable legal and regulatory requirements.

Board Considerations in Approving the Agreement

The Approval Process: At the Organizational Meeting, the Board reviewed materials relating to its consideration of the proposed Agreement. The Board considered all factors it believed relevant with respect to the Fund, including, among other factors: (a) the nature, extent and quality of the services to be provided by BlackRock; (b) the investment performance of BlackRock portfolio management; (c) the advisory fee and the estimated cost of the services and estimated profits to be realized by BlackRock and its affiliates from their relationship with the Fund; (d) the sharing of potential economies of scale; (e) fall-out benefits to BlackRock and its affiliates as a result of BlackRock’s relationship with the Fund; (f) possible alternatives to the proposed Agreement; (g) the policies and practices of BlackRock with respect to portfolio transactions for the Fund; (h) BlackRock’s portfolio compliance systems and capabilities; and (i) other factors deemed relevant by the Board Members.

In considering approval of the Agreement, the Board met with the relevant investment advisory personnel from BlackRock and considered all information it deemed reasonably necessary to evaluate the terms of the Agreement. The Board received materials in advance of the Organizational Meeting relating to its consideration of the Agreement, including (a) information independently compiled and prepared by Broadridge Financial Solutions, Inc. (“Broadridge”) regarding the Fund’s fees and estimated expense ratio as compared with a peer group of funds as determined by Broadridge (“Expense Peers”); (b) information regarding BlackRock’s economic outlook for the Fund and its general investment outlook for the markets; (c) information regarding fees paid to service providers that are affiliates of BlackRock; and (d) information outlining the legal duties of the Board under the 1940 Act with respect to the consideration and approval of the Agreement. The Board also noted information received at prior Board meetings concerning compliance records and regulatory matters relating to BlackRock.

The Board also considered other matters it deemed important to the approval process, such as other payments made to BlackRock or its affiliates relating to securities lending and cash management and BlackRock’s services related to the valuation and pricing of Fund portfolio holdings. The Board noted the willingness of BlackRock personnel to engage in open, candid discussions with the Board. The Board did not identify any particular information as determinative, and each Board Member may have attributed different weights to the various items considered.

A. Nature, Extent and Quality of the Services Provided by BlackRock

The Board, including the Independent Board Members, reviewed the nature, extent and quality of services to be provided by BlackRock, including the investment advisory services to be provided to the Fund. The Board received information concerning the investment philosophy and investment process to be used by BlackRock in managing the Fund, as well as a description of the capabilities, personnel and services of BlackRock. The Board considered the scope of the services provided by BlackRock to the Fund under the Agreement relative to services typically provided by third parties to other funds. The Board noted that the standard of care applicable under the Agreement was comparable to that found generally in investment company advisory agreements. The Board concluded that the scope of BlackRock’s services to be provided to the Fund was consistent with the Fund’s operational requirements, including, in addition to seeking to meet the Fund’s investment objective, compliance with investment restrictions, and tax and reporting requirements and related shareholder services.

The Board, including the Independent Board Members, also considered the quality of the administrative and other non-investment advisory services to be provided by BlackRock and its affiliates to the Fund. The Board evaluated the procedures of BlackRock designed to fulfill its fiduciary duty to the Fund with respect to possible conflicts of interest, including BlackRock’s code of ethics (regulating the personal trading of BlackRock’s officers and employees), the procedures by which BlackRock allocates trades among its various investment advisory clients, the integrity of the systems in place to ensure compliance with the foregoing and the record of BlackRock in these matters. The Board also noted information received at prior Board meetings concerning standards of BlackRock with respect to the execution of portfolio transactions.

The Board considered, among other factors, with respect to BlackRock: the number, education and experience of investment personnel generally and the Fund’s portfolio management team; BlackRock’s research capabilities; investments by portfolio managers in the funds they manage; portfolio trading capabilities; use of technology;

Board Review and Approval of Investment Advisory Contract (continued)

commitment to compliance; credit analysis capabilities; risk analysis and oversight capabilities; and the approach to training and retaining portfolio managers and other research, advisory and management personnel. The Board also considered BlackRock’s overall risk management program, including the continued efforts of BlackRock and its affiliates to address cybersecurity risks and the role of BlackRock’s Risk & Quantitative Analysis Group. The Board engaged in a review of BlackRock’s compensation structure with respect to the Fund’s portfolio management team and BlackRock’s ability to attract and retain high-quality talent and create performance incentives. The Board also considered the business reputation of BlackRock and its financial resources and concluded that BlackRock would be able to meet any reasonably foreseeable obligation under the Agreement.

The Board also considered that BlackRock and its affiliates will provide the Fund with certain administrative, shareholder and other services (in addition to any such services provided to the Fund by third parties) and officers and other personnel as are necessary for the operations of the Fund, as applicable. In particular, BlackRock and its affiliates will provide the Fund with certain administrative services, including, among others: (i) responsibility for disclosure documents, such as the prospectus, the summary prospectus, the statement of additional information and periodic shareholder reports; (ii) oversight of daily accounting and pricing; (iii) responsibility for periodic filings with regulators; (iv) overseeing and coordinating the activities of other service providers, including, among others, the Fund’s administrator, custodian, fund accountant, transfer agent, and auditor; (v) organizing Board meetings and preparing the materials for such Board meetings; (vi) providing legal and compliance support; and (vii) performing or managing administrative functions necessary for the operation of the Fund, such as tax reporting, expense management, fulfilling regulatory filing requirements, overseeing the Fund’s distribution partners, and shareholder call center and other services. The Board considered the structure and duties of BlackRock’s fund administration, shareholder services, and legal & compliance departments, and considered BlackRock’s policies and procedures for assuring compliance with applicable laws and regulations.

B The Investment Performance of the Fund and BlackRock

The Board, including the Independent Board Members, previously received and considered information about BlackRock’s investment performance for other funds. The Board, however, did not consider the performance history of the Fund because the Fund was newly organized and had not yet commenced operations as of the date of the Organizational Meeting.

C. Consideration of the Advisory/Management Fees and the Estimated Cost of the Services to be Provided and Estimated Profits to be Realized by BlackRock and its Affiliates from their Relationship with the Fund

The Board, including the Independent Board Members, reviewed the Fund’s contractual advisory fee rate compared with those of its Expense Peers, noting that the Agreement provides for a unitary fee structure that includes advisory and administration services. Under the unitary fee structure, the Fund pays a single fee to the Manager and the Manager will pay all operating expenses of the Fund, except the advisory fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and extraordinary expenses. The contractual advisory fee rate does not take into account any reimbursements or fee waivers. The Board also compared the Fund’s estimated total expense ratio, as well as its estimated actual advisory fee rate, to those of its Expense Peers. The total expense ratio gives effect to any expense reimbursements or fee waivers that benefit a fund, and the actual advisory fee rate gives effect to any advisory fee reimbursements or waivers that benefit a fund. Additionally, the Board noted information received at prior Board meetings concerning the services provided and the fees charged by BlackRock and its affiliates to other types of clients with similar investment mandates, as applicable, including institutional accounts, exchange-traded funds, mutual funds and sub-advised mutual funds (including mutual funds sponsored by third parties).

The Board noted that the Fund’s contractual advisory fee rate ranked in the first quartile, and that the estimated actual advisory fee rate and the estimated total expense ratio each ranked in the first quartile, relative to the Fund’s Expense Peers. The Board further noted that the Fund has an advisory fee arrangement that includes breakpoints that adjust the fee rate downward as the size of the Fund increases above certain contractually specified levels. The Board noted that if the size of the Fund were to decrease, the Fund could lose the benefit of one or more breakpoints. The Board noted that BlackRock has voluntarily agreed to waive a portion of the advisory fee payable by the Fund.

Following consideration of this information, the Board, including the independent Board Members, concluded that the fees to be paid pursuant to the Agreement were fair and reasonable in light of the services provided.

As the Fund had not commenced operations as of the date of the Organizational Meeting, BlackRock was not able to provide the Board with specific information concerning the expected profits to be realized by BlackRock and its affiliates from their relationships with the Fund. BlackRock, however, will provide the Board with such information at future meetings.

D. Economies of Scale

The Board, including the Independent Board Members, considered the extent to which economies of scale might be realized as the assets of the Fund increase, including the existence of fee waivers and/or expense caps, as applicable, noting that any contractual fee waivers and expense caps had been approved by the Board.

E. Other Factors Deemed Relevant by the Board Members

The Board, including the Independent Board Members, also took into account other ancillary or “fall-out” benefits that BlackRock or its affiliates may derive from BlackRock’s respective relationships with the Fund, both tangible and intangible, such as BlackRock’s ability to leverage its investment professionals who manage other portfolios and risk management personnel, an increase in BlackRock’s profile in the investment advisory community, and the engagement of BlackRock’s affiliates as service providers to the Fund, including for distribution, securities lending and cash management services. The Board also considered BlackRock’s overall operations and its efforts to expand


26		2 0 1 9 B L A C K R O C K A N N U A L R E P O R T T O S H A R E H O L D E R S

Board Review and Approval of Investment Advisory Contract (continued)

the scale of, and improve the quality of, its operations. The Board also noted that, subject to applicable law, BlackRock may use and benefit from third-party research obtained by soft dollars generated by certain registered fund transactions to assist in managing all or a number of its other client accounts.

The Board, including the Independent Board Members, concluded that these ancillary benefits that BlackRock and its affiliates could receive with regard to providing investment advisory and other services to the Fund were consistent with those generally available to other exchange-traded-fund sponsors. The Board concluded that any such ancillary benefits would not be disadvantageous to the Fund and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the Agreement.

In connection with its consideration of the Agreement, the Board also received information regarding BlackRock’s brokerage and soft dollar practices. The Board received reports from BlackRock which included information on brokerage commissions and trade execution practices that it had received at prior Board meetings.

Conclusion

The Board, including all the Independent Board Members, unanimously approved the Agreement between the Manager and the Trust, with respect to the Fund, for a two-year term beginning on the effective date of the Agreement. Based upon its evaluation of all of the aforementioned factors in their totality, as well as other information, the Board, including the Independent Board Members, was satisfied that the terms of the Agreement were fair and reasonable and in the best interest of the Fund and its shareholders. In arriving at its decision to approve the Agreement, the Board did not identify any single factor or group of factors as all-important or controlling, but considered all factors together, and different Board Members may have attributed different weights to the various factors considered. The Independent Board Members were also assisted by the advice of independent legal counsel in making this determination.

Supplemental Information (unaudited)

Premium/Discount Information

The Premium/Discount Information section is intended to present information about the differences between the daily market price on secondary markets for shares of a fund and that fund’s NAV. NAV is the price at which a fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The “Market Price” of a fund generally is determined using the midpoint between the highest bid and the lowest ask on the primary securities exchange on which shares of such fund are listed for trading, as of the time that the fund’s NAV is calculated. A fund’s Market Price may be at, above or below its NAV. The NAV of a fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of a fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of a fund on a given day, generally at the time the NAV is calculated. A premium is the amount that a fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that a fund is trading below the reported NAV, expressed as a percentage of the NAV.

Premium/discount information for the Fund covering the most recently completed calendar year and the most recently completed calendar quarters since that year (or since the Fund began trading, if shorter) is publicly accessible, free of charge, at www.blackrock.com.

The following information shows the frequency of distributions of premiums and discounts for the Fund for the immediately preceding five calendar years (or from the date the Fund began trading on the secondary market, if less than five years) through the date of the most recent calendar quarter-end. Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. Premium/discount ranges with no trading days are omitted. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by each table. All data presented here represents past performance, which cannot be used to predict future results.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

The Committee has adopted policies and procedures with regard to the pre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the Investment Adviser and Affiliated Service Providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are (a) consistent with the SEC’s auditor independence rules and (b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis (“general pre-approval”). The term of any general pre-approval is 12 months from the date of the pre-approval, unless the Committee provides for a different period. Tax or other non-audit services provided to the registrant which have a direct impact on the operations or financial reporting of the registrant will only be deemed pre-approved provided that any individual project does not exceed $10,000 attributable to the registrant or $50,000 per project. For this purpose, multiple projects will be aggregated to determine if they exceed the previously mentioned cost levels.

Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. At this meeting, an analysis of such services is presented to the Committee for ratification. The Committee may delegate to the Committee Chairman the authority to approve the provision of and fees for any specific engagement of permitted non-audit services, including services exceeding pre-approved cost levels.

(e)(2) None of the services described in each of Items 4(b) through (d) were approved by the Committee pursuant to the de minimus exception in paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not Applicable

(g) The aggregate non-audit fees, defined as the sum of the fees shown under “Audit-Related Fees,” “Tax Fees” and “All Other Fees,” paid to the accountant for services rendered by the accountant to the registrant, the Investment Adviser and the Affiliated Service Providers were:


Entity Name	Current Fiscal Year End	Previous Fiscal Year End
BlackRock U.S. Equity Factor Rotation ETF	$8,800	N/A


		(h) The Committee has considered and determined that the provision of non-audit services that were rendered to the Investment Adviser and the Affiliated Service Providers that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant’s independence.
