Investment Objective

The investment objective of the WCM Small Cap Growth Fund (the “Fund”) is long-term capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that 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.

1

from the Fund, subject to certain limitations, of fees waived or payments made to the Fund for a period ending three years after the date of the waiver or payment. This reimbursement may be requested from the Fund if the reimbursement will not cause the Fund’s annual expense ratio to exceed the lesser of (a) the expense limitation in effect at the time such fees were waived or payments made, or (b) the expense limitation in effect at the time of the reimbursement.

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 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. The example reflects the Fund’s contractual fee waiver and/or expense reimbursement for the term of the contractual fee waiver and/or expense reimbursement.

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 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 89% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of small-capitalization companies. The Fund primarily invests in common stocks of U.S. companies. The Fund may also invest in real estate investment trusts (“REITs”). The Fund’s advisor considers small-capitalization companies to be companies with market capitalizations within the range of those companies included in the Russell 2000^® Index at the time of purchase. Because small-capitalization companies are defined by reference to an index, the range of market capitalization of companies in which the Fund invests may vary with market conditions. As of March 31, 2026, the market capitalizations of companies included in the Russell 2000^® Index were between $4.39 million and $38.01 billion. Investments in companies that move above or below the capitalization range of the companies comprising the Russell 2000^® Index may continue to be held by the Fund in the Fund advisor’s sole discretion.

The Fund’s advisor uses a bottom-up approach that seeks to identify companies believed to have above-average potential for growth in the rate of return on invested capital and assets. The advisor’s investment process seeks companies that are industry leaders with sustainable competitive advantages; corporate cultures emphasizing strong, quality and experienced management; little or no debt; attractive relative valuations; and potential for asset base growth. The Fund’s advisor employs a dynamic process to analyze corporate performance and valuation, which includes evaluating the current trajectory and outlook for each company held by the Fund, as well as the value the market is assigning to the cash flow the company can generate. In selecting securities, the Fund’s advisor also considers other factors including, among others, political risk, monetary policy risk, and regulatory risk.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Fund, carefully consider these risk factors associated with investing in the Fund, which may cause investors to lose money. There can be no assurance that the Fund will achieve its investment objective.

2

Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic, political, or geopolitical conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as tariffs, labor shortages or increased production costs and competitive conditions within an industry. In addition, local regional or global events such as war, acts of terrorism, international conflicts, trade disputes, supply chain disruptions, cybersecurity events, technological advances (such as artificial intelligence and machine learning), the spread of infectious illness or other public health issues, natural disasters or climate events, or other events could have a significant impact on a security or instrument. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests.

Small-Cap Company Risk. The securities of small-capitalization companies may be subject to more abrupt or erratic market movements and may have lower trading volumes or more erratic trading than securities of larger, more established companies or market averages in general. In addition, such companies typically are more likely to be adversely affected than large capitalization companies by changes in earning results, business prospects, investor expectations or poor economic or market conditions.

Sector Focus Risk. The Fund may invest a larger portion of its assets in one or more sectors than many other mutual funds, and thus will be more susceptible to negative events affecting those sectors. For example, as of December 31, 2025, 29.6% and 25.4% of the Fund’s assets were invested in the industrials sector and health care sector, respectively. Performance of companies in the industrials sector may be affected by, among other things, supply and demand for their specific product or service and for industrial sector products in general. Moreover, government regulation, world events, exchange rates and economic conditions, technological developments, fuel prices, labor agreements, insurance costs, and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Performance of companies in the health care sector may be affected by, among other things, government regulation, industry innovation, and extensive litigation based on product liability and similar claims.

Growth-Oriented Investment Strategies Risk. Growth funds generally focus on stocks of companies believed to have above-average potential for growth in revenue and earnings. Growth securities typically are very sensitive to market movements because their market prices frequently reflect projections of future earnings or revenues, and when it appears that those expectations will not be met, the prices of growth securities typically fall.

Liquidity Risk. The Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. Illiquid assets may also be difficult to value.

Management and Strategy Risk. The value of your investment depends on the judgment of the Fund’s advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

Recent Market Events. Periods of market volatility may occur in response to market events, public health emergencies, natural disasters or climate events, and other economic, political, and global macro factors. U.S. and international markets have recently experienced, and may continue to experience, periods of significant volatility due to various factors, including uncertainty regarding inflation and central banks’ interest rate changes, the possibility of a national or global recession, trade tensions and tariffs, and political and geopolitical events. In addition, wars or threats of war and aggression, such as Russia’s invasion of Ukraine and conflicts among nations and militant groups

in the Middle East, have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund’s investments. Additionally, since the change in the U.S. presidential administration in 2025, the administration has pursued an aggressive foreign policy agenda, including through suggestions that the United States should control certain sovereign foreign territories, attempts to restructure federal government agencies with international influence, and the imposition of tariffs and trade barriers on certain foreign countries, including China and long-time U.S. allies. These and other similar events could be prolonged and could adversely affect the value and liquidity of the Fund’s investments, impair the Fund’s ability to satisfy redemption requests, and negatively impact the Fund’s performance.

REIT Risk. The Fund’s investment in REITs will subject the Fund to risks similar to those associated with direct ownership of real estate, including losses from casualty or condemnation, and changes in local and general economic conditions, supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses.

Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data (including private shareholder information), or proprietary information, or cause the Fund, the Fund’s advisor, and/or other service providers (including custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality. In an extreme case, a shareholder’s ability to exchange or redeem Fund shares may be affected. The use of artificial intelligence and machine learning could exacerbate these risks. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of those securities could decline if the issuers experience cybersecurity incidents.

Performance

The bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year for Institutional Class shares and by showing how the average annual total returns of each class of the Fund compare with the average annual total returns of the Russell 3000 Index and the Russell 2000 Growth Index. The Russell 3000 Index has been included as the Fund’s primary broad-based securities market index in order to satisfy regulatory requirements. The Fund also compares its performance with the returns of Russell 2000 Growth Index, which the Advisor believes is a better performance benchmark for comparison to the Fund’s performance in light of the Fund’s investment strategies. Performance for classes other than those shown may vary from the performance shown to the extent the expenses for those classes differ. Updated performance information is available at the Fund’s website www.wcminvest.com/funds, or by calling the Fund at 1-888-988-9801. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

Tax Information

The Fund’s distributions are generally taxable, and will ordinarily be taxed as ordinary income, qualified dividend income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account. Shareholders investing through such tax-advantaged arrangements may be taxed later upon withdrawal of monies from those arrangements.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services.

Ask your salesperson or visit your financial intermediary’s website for more information.
