SCHX Schwab US Large Cap

Principal Investment Strategies

To pursue its goal, the fund generally invests in securities that are included in the Bloomberg Barclays US 5-10 Year Corporate Bond Index^†. The index measures the performance of U.S. investment grade, taxable corporate bonds with maturities greater than or equal to five years and less than ten years that have $300 million or more of outstanding face value. The securities in the index must be denominated in U.S. dollars and must be fixed-rate. The index includes securities publicly issued by U.S. and non-U.S. industrial, utility and financial issuers. The index excludes certain types of securities, including contingent capital securities, inflation-linked bonds, floating-rate bonds, taxable and tax-exempt municipal securities, and structured notes. The index is market capitalization weighted and the securities in the index are updated on the last business day of each month. As of December 31, 2019, there were approximately 1,777 securities in the index.

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 securities included in the index. The fund will notify its shareholders at least 60 days before changing this policy.

Under normal circumstances, the fund may invest up to 10% of its net assets in securities not included in its 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; (b) high-quality liquid investments, such as securities issued by the U.S. government, its agencies or instrumentalities, including obligations that are not guaranteed by the U.S. Treasury, and obligations that are issued by private issuers; (c) other investment companies; and (d) derivatives, principally futures contracts. The fund may use futures contracts and other derivatives primarily to help manage interest rate exposure. The fund may also invest in cash and cash equivalents, including money market funds, and lend its securities to minimize the difference in performance that naturally exists between an index fund and its corresponding index.

Because it may not be possible or practical to purchase all of the securities in the index, the fund’s investment adviser will seek to track the total return of the index by using sampling techniques. Sampling techniques involve investing in a limited number of index securities that, when taken together, are expected to perform similarly to the index as a whole. These techniques are based on a variety of factors, including interest rate and yield curve risk, maturity exposures, industry, sector and issuer weights, credit quality, and other risk factors and characteristics. The fund expects that its portfolio will hold less than the total number of securities in the index, but reserves the right to hold as many securities as it believes necessary to achieve the fund’s investment objective. The fund may sell securities that are represented in the index in

anticipation of their removal from the index. The fund generally expects that its maturity will be similar to that of the index. In addition, the fund generally expects that its weighted average duration will closely correspond to the weighted average duration of the index, which as of December 31, 2019, was 6.15 years.

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 its index is so concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

The investment adviser seeks to achieve, over time, a correlation between the fund’s performance and that of its 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 its index, including the degree to which the fund uses a sampling technique (or otherwise gives a different weighting to a security than the index does). The correlation between the performance of the fund and its index may also diverge due to transaction costs, asset valuations, 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. Market disruptions could cause delays in the index’s rebalancing schedule which may result in the index and, in turn, the fund experiencing returns different than those that would have been achieved under a normal rebalancing schedule.

Interest Rate Risk. Interest rates rise and fall over time. As with any investment whose yield reflects current interest rates, the fund’s yield will change over time. During periods when interest rates are low, the fund’s yield (and total return) also may be low. Changes in interest rates also may affect the fund’s share price: a rise in interest rates generally causes the fund’s share price to fall. The longer the fund’s portfolio duration, the more sensitive to interest rate movements its share price is likely to be. Also, a change in a central bank’s monetary policy or economic conditions, among other things, may result in a change in interest rates, which could have sudden and unpredictable effects on the markets and significantly impact the value of fixed-income securities in which the fund invests.

Credit Risk. A decline in the credit quality of an issuer, guarantor or liquidity provider of a portfolio investment or a counterparty could cause the fund to lose money or underperform. The fund could lose money if, due to a decline in credit quality, the issuer, guarantor or liquidity provider of a portfolio investment or a counterparty fails to make, or is perceived as being unable or unwilling to make, timely principal or interest payments or otherwise honor its obligations.

Sampling Index Tracking Risk. The fund may not fully replicate the index and may hold securities not included in the index. As a result, the fund is subject to the risk that the investment adviser’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. Because the fund uses a sampling approach it may not track the return of the index as well as it would if the fund purchased all of the securities in the index.

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.

Non-U.S. Issuer Risk. The fund may invest in U.S.-registered, dollar-denominated bonds of non-U.S. corporations. The fund’s investments in bonds of non-U.S. issuers may involve certain risks that are greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; the imposition of economic sanctions or other government restrictions; differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs. These risks may be heightened in connection with bonds issued by non-U.S. corporations and entities in emerging markets.

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 the fund’s 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.

Performance

Because the fund has not completed a full calendar year of operations, no performance figures are given. Once the fund has completed a full calendar year of operations, a bar chart and table will be included that will provide some indication of the risks of investing in the fund by showing the variability of the fund’s returns and comparing the fund’s performance to the index. For current performance information, once available, please see www.schwabfunds.com/schwabetfs_prospectus.

Purchase and Sale of Fund Shares

The fund issues and redeems shares at its NAV only in large blocks of shares, typically 50,000 shares or more (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. Except when aggregated in Creation Units, shares of the fund are not redeemable securities.

Individual shares of the fund trade on national securities exchanges and elsewhere during the trading day and can only be bought and sold at market prices throughout the trading day through a broker-dealer. Because fund shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (premium) or less than NAV (discount).

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.

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.
