Investment Objective

The fund’s goal is to track as closely as possible, before fees and expenses, the total return of the Dow Jones U.S. Large-Cap Total Stock Market Index.

Fund Fees and Expenses

This table describes the fees and expenses you may pay if you buy, hold and sell shares 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.

Shareholder Fees (fees paid directly from your investment)
​	None

Annual Fund Operating Expenses (expenses that you pay each year as a % of the value of your investment)
Management fees	0.03
Other expenses	None
Total annual fund operating expenses	0.03

Example

This example is intended to help you compare the cost of investing in 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 time periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. Your actual costs may be higher or lower.

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 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. During the most recent fiscal year, the fund’s portfolio turnover rate was 4% of the average value of its portfolio.

Principal Investment Strategies

To pursue its goal, the fund generally invests in stocks that are included in the Dow Jones U.S. Large-Cap Total Stock Market Index†. The index includes the large-cap portion of the Dow Jones U.S. Total Stock Market Index actually available to investors in the marketplace. The Dow Jones U.S. Large-Cap Total Stock Market Index includes the components ranked 1-750 by full market capitalization. The index is a float-adjusted market capitalization weighted index. As of August 31, 2022, the index was composed of 756 stocks.

It is the fund’s policy that under normal circumstances it will invest at least 90% of its net assets (including, for this purpose, any borrowings for investment purposes) in these stocks. The fund will notify its shareholders at least 60 days before changing this policy. The fund generally will seek to replicate the performance of the index by giving the same weight to a given stock as the index does. However, when the investment adviser believes it is appropriate to do so, such as to avoid purchasing odd-lots (i.e., purchasing less than the usual number of shares traded for a security), for tax considerations, or to address liquidity considerations with respect to a stock, the investment adviser may cause the fund’s weighting of

a stock to be more or less than the index’s weighting of the stock. The fund may sell securities that are represented in the index in anticipation of their removal from the index, or buy securities that are not yet represented in the index in anticipation of their addition to the index.

Under normal circumstances, the fund may invest up to 10% of its net assets in securities not included in the index. The principal types of these investments include those that the investment adviser believes will help the fund track the index, such as investments in (a) securities that are not represented in the index but the investment adviser anticipates will be added to the index or as necessary to reflect various corporate actions (such as mergers and spin-offs); (b) other investment companies; and (c) derivatives, principally futures contracts. The fund may use futures contracts and other derivatives primarily to seek returns on the fund’s otherwise uninvested cash assets to help it better track the index. The fund may also invest in cash and cash equivalents, including money market funds, and may lend its securities to minimize the difference in performance that naturally exists between an index fund and its corresponding index.

The fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry, group of industries or sector to approximately the same extent that the index is so concentrated.

The investment adviser seeks to achieve, over time, a correlation between the fund’s performance and that of the index, before fees and expenses, of 95% or better. However, there can be no guarantee that the fund will achieve a high degree of correlation with the index. A number of factors may affect the fund’s ability to achieve a high correlation with the index, including the degree to which the fund utilizes a sampling technique (which involves investing in a limited number of index securities which, when taken together, are expected to perform similarly to the index as a whole). The correlation between the performance of the fund and the index may also diverge due to transaction costs, asset valuations, corporate actions (such as mergers and spin-offs), timing variances, and differences between the fund’s portfolio and the index resulting from legal restrictions (such as diversification requirements) that apply to the fund but not to the index.

Principal Risks

The fund is subject to risks, any of which could cause an investor to lose money. The fund’s principal risks include:

Market Risk. Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory and other conditions, including economic sanctions and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. As with any investment whose performance is tied to these markets, the value of an investment in the fund will fluctuate, which means that an investor could lose money over short or long periods.

Investment Style Risk. The fund is an index fund. Therefore, the fund follows the securities included in the index during upturns as well as downturns. Because of its indexing strategy, the fund does not take steps to reduce market exposure or to lessen the effects of a declining market. In addition, because of the fund’s expenses, the fund’s performance may be below that of the index. Errors relating to the index may occur from time to time and may not be identified by the index provider for a period of time. In addition, market disruptions could cause delays in the index’s rebalancing schedule. Such errors and/or market disruptions may result in losses for the fund.

Equity Risk. The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities market as a whole. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Market Capitalization Risk. Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. During a period when securities of a particular market capitalization fall behind other types of investments, the fund’s performance could be impacted.

Large-Cap Company Risk. Large-cap companies are generally more mature and the securities issued by these companies may not be able to reach the same levels of growth as the securities issued by small- or mid-cap companies.

Tracking Error Risk. As an index fund, the fund seeks to track the performance of the index, although it may not be successful in doing so. The divergence between the performance of the fund and the index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant.

Derivatives Risk. The fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. The fund’s use of derivatives could reduce the fund’s performance, increase its volatility and cause the fund to lose more than the initial amount invested. In addition, investments in derivatives may involve leverage, which means a small percentage of assets invested in derivatives can have a disproportionately large impact on the fund.

Liquidity Risk. The fund may be unable to sell certain securities, such as illiquid securities, readily at a favorable time or price, or the fund may have to sell them at a loss.

Securities Lending Risk. Securities lending involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent.

Concentration Risk. To the extent that the fund’s or the index’s portfolio is concentrated in the securities of issuers in a particular market, industry, group of industries, sector or asset class, the fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more

vulnerable to adverse economic, market, political or regulatory occurrences affecting that market, industry, group of industries, sector or asset class.

Market Trading Risk. Although fund shares are listed on national securities exchanges, there can be no assurance that an active trading market for fund shares will develop or be maintained. If an active market is not maintained, investors may find it difficult to buy or sell fund shares.

Shares of the Fund May Trade at Prices Other Than NAV. Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of the shares of the fund will approximate the fund’s net asset value (NAV), there may be times when the market price and the NAV vary significantly. An investor may pay more than NAV when buying shares of the fund in the secondary market, and an investor may receive less than NAV when selling those shares in the secondary market. The market price of fund shares may deviate, sometimes significantly, from NAV during periods of market volatility or market disruption.

Purchase and Sale of Fund Shares

The fund issues and redeems shares at its NAV only in large blocks of shares (Creation Units). These transactions are usually in exchange for a basket of securities included in the index and/or an amount of cash. As a practical matter, only Authorized Participants purchase or redeem Creation Units.

Individual shares may only be purchased and sold in the secondary market (i.e., on a national securities exchange) through a broker or dealer at market prices. Because fund shares trade at market prices rather than at NAV, fund shares may trade at a price greater than NAV (premium) or less than NAV (discount). When buying or selling shares in the secondary market, you 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) (the

Schwab U.S. Large-Cap ETF | Summary Prospectus3​

“bid-ask spread”). Recent information regarding the fund’s NAV, market price, premiums and discounts, and bid-ask spreads is available at www.schwabassetmanagement.com.

Tax Information

Dividends and capital gains distributions received from the fund will generally be taxable as ordinary income or capital gains, unless you are investing through an IRA, 401(k) or other tax-advantaged account (in which case you may be taxed later, upon withdrawal of your investment from such account).

Payments to Financial Intermediaries

If you purchase shares of the fund through a broker-dealer or other financial intermediary (such as a bank), the adviser and its related companies may pay the intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
