EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem or hold 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 Fund 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 111% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Large Cap Disciplined Equity Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in equity securities of large companies. These securities may include common stocks, preferred stocks, depositary receipts, warrants, exchange-traded funds (ETFs) and real estate investment trusts (REITs) based on a large capitalization equity index and equity securities of foreign companies. The Fund will invest primarily in common stocks of U.S. companies with market capitalizations in the range of companies in the S&P 500 Index (between $7.03 billion and

$4.85 trillion as of July 31, 2026) at the time of purchase. The market capitalization range and the composition of the S&P 500 Index are subject to change. The Fund may also, to a lesser extent, invest in common and preferred stocks of small and medium capitalization companies.

The Fund seeks to exceed the total return of the S&P 500 Index, with a similar level of volatility, by investing primarily in a portfolio of common stocks included in the S&P 500 Index, as well as other equity investments and derivative instruments whose value is derived from the performance of the S&P 500 Index. The Fund uses a multi-manager approach, relying on one or more sub-advisers (each, a Sub-Adviser and collectively, the Sub-Advisers) with differing investment philosophies to manage portions of the Fund’s portfolio under the general supervision of SEI Investments Management Corporation (SIMC or the Adviser). The Fund may employ Sub-Advisers that use a variety of different methods to seek to outperform the Fund’s benchmark, including purchasing stocks with strong anticipated future earnings growth, selecting stocks that the Sub-Adviser believes are undervalued relative to their fundamentals, capturing returns from the natural volatility of the market and employing strategies that rotate among various sectors of the market. The Fund may also utilize one or more additional Sub-Advisers who manage in a complementary style with the objective to seek to add value over the S&P 500 Index while maintaining a similar level of volatility to the S&P 500 Index. Due to its investment strategy, the Fund may buy and sell securities frequently.

One or more Sub-Adviser(s) may implement a long/short equity investment strategy by investing in securities believed to offer capital appreciation opportunities while also attempting to take advantage of an anticipated decline in the price of a company. A long/short equity investment strategy takes (i) long positions with respect to investments that the Sub-Adviser believes to be undervalued relative to their potential increase in price, and (ii) short positions (including through derivatives instruments such as swaps) with respect to investments that the Sub-Adviser believes to be overvalued and likely to decrease in price. A long/short equity investment strategy seeks returns from strong security selection on both the long and short sides. These long and short positions may be completely unrelated.
