The fund’s goal is to track as closely as possible, before fees and expenses, the total return of an index composed of U.S. real estate investment trusts classified as equities.

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.

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 10% of the average value of its portfolio.

To pursue its goal, the fund generally invests in securities that are included in the Dow Jones Equity All REIT Capped Index^†. The index is a float-adjusted market capitalization weighted index that is subject to capping constraints at each quarterly rebalancing. The index generally includes all publicly traded equity real estate investment trusts (REITs) with a minimum float-adjusted market capitalization of $200 million and a three-month median daily value traded of at least $5 million. A security becomes ineligible if its float-adjusted market capitalization falls below $100 million for two consecutive quarters. The index excludes mortgage REITs, defined as REITs that lend money directly to real estate owners and/or operators or indirectly through the purchase of mortgages or mortgage-backed securities, and hybrid REITs, defined as REITs that participate both in equity and mortgage investing. As of February 27, 2026, the index was composed of 116 REITs.

The index uses a capping methodology to limit the weight of the securities of any single issuer (as determined by the index provider) to a maximum of 10% of the index. Additionally, the capping methodology limits the sum of the weights of the securities of all issuers that individually constitute more than 4.5% of the weight of the index to a maximum of 22.5% of the weight of the index in the aggregate. In order to implement this capping methodology, the index constrains at quarterly rebalance: (i) the weight of any single issuer to a maximum of 10%, and (ii) the aggregate weight of all issuers that individually exceed 4.5% of the index weight to a maximum of 22.5%. Between scheduled quarterly index reviews, the index is reviewed daily to assess whether the sum of all individual constituents with more than 5% of the weight of the index exceeds more than 25% of the weight of the index in the aggregate. When daily capping is necessary, the changes are announced after the close of the business day on which the daily weight caps are exceeded, with the reference date after the close of that same business day, and changes are effective after the close of the next trading day.

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. The fund will generally seek to replicate the performance of the index by giving the same weight to a given security as the index does. However, when the investment adviser believes it is in the best interest of the fund, 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 security, the investment adviser may cause the fund’s weighting of a security to be more or less than the index’s weighting of the security. 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 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) 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, cash equivalents and 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.

Due to the composition of the index, the fund will concentrate its investments (i.e., hold more than 25% of its total assets) in real estate companies and companies related to the real estate industry. The fund may also invest in a particular industry, group of industries or sector to approximately the same extent that its index is so concentrated.

The bar chart below shows how the fund’s investment results have varied from year to year, and the following table shows how the fund’s average annual total returns for various periods compared to that of one or more indices. The S&P 500 Index serves as the fund’s regulatory index and provides a broad measure of market performance. The fund generally invests in securities that are included in the Dow Jones Equity All REIT Capped Index. The fund does not seek to track the regulatory index. This information provides some indication of the risks of investing in the fund. All figures assume distributions were reinvested. Keep in mind that future performance (both before and after taxes) may differ from past performance. For current performance information, please see www.schwabassetmanagement.com/prospectus.

The after-tax figures reflect the highest individual federal income tax rates in effect during the period and do not reflect the impact of state and local taxes. Your actual after-tax returns depend on your individual tax situation. In addition, after-tax returns are not relevant if you hold your fund shares through a tax-deferred arrangement, such as a 401(k) plan, an individual retirement account (IRA) or other tax-advantaged account. In some cases, the

return after taxes on distributions and sale of shares may exceed the fund’s other returns due to an assumed benefit from any losses on a sale of shares at the end of the measurement period.

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, tariffs, 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.

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.

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.

Small-Cap Company Risk — Securities issued by small-cap companies may be riskier than those issued by larger companies, and their prices may move sharply, especially during market upturns and downturns.

REITs Risk — In addition to the risks associated with investing in securities of real estate companies and real estate related companies, REITs are subject to certain additional risks. Equity REITs may be affected by changes in the value of the underlying properties owned by the trusts. Further, REITs are dependent upon specialized management skills and cash flows, and may have their investments in relatively few properties, or in a small geographic area or a single property type. Failure of a company to qualify as a REIT under federal tax law may have adverse consequences to the fund. In addition, REITs have their own expenses, and the fund will bear a proportionate share of those expenses. The value of a REIT may be affected by changes in interest rates.

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 could 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.

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.
