described in the “Management of the Fund” section of the Fund’s prospectus beginning on page 25, BlackRock has contractually agreed to waive the management fee with respect to any portion of the Fund’s assets
estimated to be attributable to investments in other equity and fixed-income mutual funds and exchange-traded funds (“ETFs”) managed by BlackRock or its affiliates that have a contractual management fee, through June 30, 2026. In addition,
BlackRock has contractually agreed to waive its management fees by the amount of investment advisory fees the Fund pays to BlackRock indirectly through its investment in money
market funds managed by BlackRock or its affiliates, through June 30, 2026. The contractual agreements 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.

Example:
This Example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in shares of the Fund for the time periods indicated and
then redeem 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:

Portfolio Turnover:
The Fund pays
transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher
transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the
Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 19% of the average value of its portfolio.

Principal
Investment Strategies of the Fund
The Fund seeks to track the investment results of the Russell 3000® Index (the “Underlying Index”), which measures the performance of the broad U.S. equity market. As of October 31, 2024, the Underlying Index included issuers
representing approximately 98% of the total market capitalization of all publicly-traded U.S.-domiciled equity securities. The Underlying Index is a float-adjusted capitalization-weighted index of the largest public issuers domiciled in the
United States and its territories. Total market capitalization reflects all equity shares outstanding, while total market value reflects float-adjusted capitalizations based on equity shares available for general investment. The Underlying
Index may include large-, mid- or small-capitalization companies, and components primarily include technology, consumer discretionary and industrials companies. The components of the Underlying Index and the degree to which these
components represent certain industries may change over time.
BlackRock uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment
profile similar to that of the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental
characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.
The Fund generally invests at least 90% of its assets, plus the amount of any borrowing for investment purposes, in
securities of the Underlying Index.
Principal Risks of Investing in the Fund
Risk is inherent in all investing. The value of your investment in the Fund, as well as
the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a
summary description of the principal risks of investing in the Fund. The relative significance of each risk factor below may change over time and you should review each risk factor carefully.
◼
Equity Securities Risk — 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.
◼
Index Fund Risk — An index fund has operating and other expenses while an index does not. As a result, while the Fund will attempt
to track the Underlying Index as closely as possible, it will tend to underperform the Underlying Index to some degree over time. If an index fund is properly correlated to its
stated index, the fund will perform poorly when the index performs poorly.
◼
Index-Related Risk — There is no guarantee that the Fund’s investment results will have a high degree of correlation to those
of the Underlying Index or that the Fund will achieve its investment objective. Market disruptions or high volatility, other unusual market circumstances and regulatory
restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index
data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which
may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen
circumstances (such as natural disasters, political unrest or war) may impact the index provider or a third-party data provider and could cause the index provider to postpone a scheduled rebalance. This could cause the Underlying Index to
vary from its normal or expected composition.
◼
Passive Investment Risk — Because BlackRock does not select individual companies in the index that the Fund tracks, the Fund may hold securities of companies that present risks that an investment adviser researching individual
securities might seek to avoid.
◼
Tracking Error Risk — The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of
the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the
Underlying Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s net asset value, differences in transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or other distributions, interest, the requirements to maintain pass-through tax treatment, portfolio transactions carried
out to minimize the distribution of capital gains to shareholders, changes to the Underlying Index and the cost to the Fund of complying with various new or existing regulatory requirements. These risks may be heightened during times of
increased market volatility or other unusual market conditions. In addition, tracking error may result because the Fund incurs fees and expenses, while the Underlying Index does
not.
3
◼
Concentration Risk — The Fund reserves the right to concentrate its investments (i.e., invest 25% or more of its total assets in securities
of issuers in a particular industry) to approximately the same extent that the Underlying Index concentrates in a particular industry. To the extent the Fund concentrates in a
particular industry, it may be more susceptible to economic conditions and risks affecting that industry.
◼
Consumer Discretionary Sector Risk — The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, supply chains, competition, consumers’
disposable income, consumer preferences, social trends and marketing campaigns.
◼
Industrials Sector Risk — 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.
◼
Issuer Risk — 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.
◼
Management Risk — As the Fund may not fully replicate the Underlying Index, it
is subject to the risk that BlackRock’s investment strategy may not produce the intended results.
◼
Market Risk and Selection Risk — 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. 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.
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, or other events could have a significant impact on the Fund and its
investments. Selection risk is the risk that the securities selected by Fund management will underperform the
markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money.
An outbreak of an infectious coronavirus (COVID-19) that was first
detected in December 2019 developed into a global pandemic that has resulted in numerous disruptions in the market and has had significant economic impact leaving general concern and uncertainty. 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. The impact of this coronavirus, and other epidemics and pandemics that may arise in the future, could affect the economies of many nations,
individual companies and the market in general ways that cannot necessarily be foreseen at the present time.
◼
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 and Mid-Capitalization Company Risk — 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.
◼
Technology Securities Risk — Certain technology-related companies may face special risks that their products or services may not prove to be commercially successful. Technology-related companies are also strongly affected by
worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental
policies. In addition, certain technology-related companies in which the Fund may invest may not currently be profitable and there can be no assurance that such companies will be
profitable in the future.
Performance Information
The information shows you how the performance of the Fund has varied for the periods
since inception and provides some indication of the risks of investing in the Fund. The table compares the Fund’s performance to that of the Russell 3000®
Index. To the extent that dividends and distributions have been paid by the Fund, the performance information for the Fund in the chart and table assumes reinvestment of the
dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. The table includes all applicable fees. If BlackRock and its affiliates had not waived or reimbursed certain Fund expenses during these
4
periods, the Fund’s returns would have
been lower. Updated information on the Fund’s performance, including its current net asset value, can be obtained by visiting www.blackrock.com or can be obtained by phone

open. Purchase orders may also be placed by calling (800) 537-4942, by mail (c/o BlackRock, P.O. Box 534429, Pittsburgh, Pennsylvania 15253-4429), or online at www.blackrock.com.
Institutional Investors are subject to a $5 million minimum initial investment requirement. Other investors, including Employer-Sponsored Retirement Plans, have no minimum

Tax Information
Different income tax rules apply depending on whether you are invested through a
qualified tax-exempt plan described in section 401(a) of the Internal Revenue Code of 1986, as amended. If you are invested through such a plan (and Fund shares are not “debt-financed property” to the plan), then the dividends paid by the Fund and the gain realized from a redemption or exchange of Fund shares will generally not be subject to U.S. federal income taxes until you
withdraw or receive distributions from the plan. If you are not invested through such a plan, then the Fund’s dividends and gain from a redemption or exchange may be subject to U.S. federal income taxes and may be taxed as ordinary income
or capital gains, unless you are a tax-exempt investor.
Payments to Broker/Dealers and Other Financial Intermediaries
If you purchase shares of the Fund through a Financial Intermediary, the Fund and
BlackRock Investments, LLC, the Fund’s distributor, or its affiliates may pay the Financial Intermediary for the sale of Fund shares and related services.
These payments may create a conflict of interest by influencing the Financial Intermediary and your individual financial
professional to recommend the Fund over another investment.
Class K Shares are only available through a Financial Intermediary if the Financial Intermediary will not receive from
Fund assets, or the Fund’s distributor’s or an affiliate’s resources, any commission payments, shareholder servicing fees (including sub-transfer agent and networking fees), or distribution fees (including Rule 12b-1 fees) with respect to
assets invested in Class K Shares.

website for more information.
