To pursue its investment objective, the fund invests primarily in U.S. common stocks. Under normal circumstances, the fund invests at least 80% of its net assets (including, for this purpose, any borrowings for investment purposes) in large-cap stocks of U.S. companies. The fund will notify its shareholders at least 60 days before changing this policy. Large-cap stocks generally are those with market capitalizations within the universe of the Russell 1000® Index at the time of purchase by the fund. The market capitalization range of the Russell 1000 Index was $228 million to $3.8 trillion, as of June 27, 2025 (the most recent index reconstitution date), and will change as market conditions change. The Russell 1000® Growth Index (the Index), the fund’s comparative index, includes those Russell 1000 Index companies with higher price-to-book ratios and higher forecasted values. The fund invests its assets in companies it believes to have above-average growth potential. Growth may be measured by factors such as earnings or revenue. Companies with high growth potential tend to have higher than average price/earnings (P/E) or price/book (P/B) ratios. Companies with strong growth potential often have new products, technologies, or other opportunities, or have a strong industry or market position. The stocks of these companies are often called “growth” stocks.

The fund actively selects portfolio securities. To aid its stock selection, the fund uses Schwab Equity Ratings®, a model that assigns ratings to approximately 3,000 U.S.-traded stocks. In addition to using Schwab Equity Ratings, the portfolio managers utilize investment data and other analytics to help manage the fund’s portfolio. Generally, when constructing the portfolio, the portfolio managers invest in stocks that are highly rated by Schwab Equity Ratings. As part of the portfolio construction process, the portfolio managers may also purchase lower-rated stocks or stocks that are not rated by Schwab Equity Ratings. This investment approach under normal conditions will result in a portfolio that maintains an overall weighting toward highly-rated stocks. For more information on Schwab Equity Ratings, please see the “More About Schwab’s Research” section in the prospectus.

When constructing the portfolio, the portfolio managers apply a research-driven, “bottom-up” approach focusing primarily on individual securities. Using both quantitative and qualitative techniques, the portfolio managers seek to identify attractive securities for equity investments. The companies are analyzed with respect to business quality, future return potential, and valuation. The portfolio managers assess the portfolio’s risk through a variety

of quantitative and qualitative measures, as well as relative to the Index.

The fund may use a portfolio optimization process to assist in constructing the portfolio. A portfolio optimization process seeks to provide an optimal balance between risk and expected return, given parameters such as the number of stocks desired in the portfolio, the level of portfolio turnover, industry and sector diversification, and volatility considerations.

The fund may invest in derivatives, principally futures contracts, primarily to seek returns on the fund’s otherwise uninvested cash assets. A futures contract is a contract to buy or sell a specific financial instrument at a specified price at a specific future time. By using these instruments, the fund potentially can offset the impact on its performance of keeping some assets in cash.

The fund may invest in exchange-traded funds (ETFs) and stocks of real estate investment trusts (REITs). The fund also may lend portfolio securities to earn additional income. Any income realized through securities lending may help fund performance.

For temporary defensive purposes during unusual economic or market conditions or for liquidity purposes, the fund may invest up to 100% of its assets in cash, money market instruments, repurchase agreements and other short-term obligations. The fund also may invest in these types of securities or hold cash while looking for suitable investment opportunities. When the fund engages in such activities, it may not achieve its investment objective.
