Sit Mid Cap Growth Fund (the "Fund") seeks to maximize 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 tables or the examples below.

 Shareholder Fees (fees paid directly from your investment)

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. It assumes that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year, that the Fund's operating expenses remain the same, and that you redeem all of your shares at the end of those periods. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year

3 Years 5 Years 10 Years

$128

$399 $690 $1,518

PORTFOLIO TURNOVER

The Fund pays transactions 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 in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 6.67% of the average value of the portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its objective by investing, under normal market conditions, at least 80% of its net assets in common stocks that, at the time of purchase, have market capitalizations that fall within the range of companies included in the Russell Midcap® Growth Index during the most recent 12-month period. The Russell Midcap® Growth Index ranged from approximately $1.07 billion to $127 billion during the 12-month period ended September 30, 2025.

Summary - Sit Mid Cap Growth Fund

Sit Investment Associates, Inc. (the "Adviser") invests in domestic growth-oriented medium to small companies it believes exhibit the potential for superior growth. The Adviser believes that a company's earnings growth is the primary determinant of its potential long-term return and evaluates a company's potential for above average long-term earnings and revenue growth. Several factors are considered in the Adviser's evaluation of a company, including:

>

unique product or service,

>

growing product demand,

>

dominant and growing market share,

>

management experience and capabilities, and

>

strong financial condition.

The Fund may invest in open-end investment companies (mutual funds) and closed-end investment companies which invest in the same types of securities in which the Fund may invest directly.

When selling equity securities for the Fund, the Adviser considers several factors, including changes in a company's fundamentals and anticipated earnings.

PRINCIPAL INVESTMENT RISKS

You could lose money by investing in the Fund. The principal risks of investing in the Fund are listed below. Different risks may be more significant at different times, depending on market conditions or other factors.

>

Market Risk: The market value of securities may fall, sometimes rapidly and unpredictably. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the markets(s) generally. Local, regional or global events such as war, acts of terrorism, other armed conflicts, tariffs, the spread of infectious illness, epidemics or other public health issues, recessions, market instability, or other events could have a significant impact on the Fund and its investments and potentially increase the risks described herein.

>

Mid Cap Stock Risk: Stocks of mid cap companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies.

>

Growth Style Investing Risk: Different types of stocks tend to shift into and out of favor with stock market investors depending on market and economic conditions. The Fund invests in growth style stocks. The Fund's performance may at times be better or worse than the performance of funds that focus on other types of stocks or that have a broader investment style.

>

Small Cap Stock Risk: Stocks of smaller companies involve substantial risk. Prices of small cap stocks may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Additionally, for certain small cap stocks, there may also be limited liquidity or trading opportunities at a favorable price or time.

>

Sector Risk: To the extent the Fund invests a significant portion of its assets in the securities of companies in the same sector of the market or region, an adverse economic, business or political development affecting that sector or region may affect the value of the Fund's investments more, and the Fund's investments may be more volatile, than if its investments were not so concentrated in such economic sector or geographic region.

>

Investment Company Risk: To the extent that the Fund invests in shares of another investment company, it will indirectly absorb its pro rata share of such investment company's operation expenses, including investment advisory and administrative fees, which will reduce the Fund's return on such investment relative to investment alternatives that do not include such expenses. In addition, the ability of the Fund to achieve its investment objective will partially depend upon the ability of the acquired fund to achieve its investment objective.

>

Management Risk: A strategy used by the investment management team may not produce the intended results.

>

Cybersecurity Risk: Cybersecurity breaches may allow an unauthorized party to gain access to Fund assets, shareholder data, or proprietary information, or cause the Fund and/or its service providers to suffer data corruption or lose operational functionality. The issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cyber attacks or other cybersecurity breaches.

HISTORICAL PERFORMANCE

The following bar chart and table provide information on the Fund's volatility and performance. The Fund's past performance before and after taxes is not necessarily an indication of how the Fund will perform in the future. The bar chart below is intended to provide you with an indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year.

The table below compares the Fund's performance over different time periods to that of a broad-based securities market index and a more narrowly-based index that reflects the market sectors in which the Fund invests (each, an "Index"). The table includes returns both before and after taxes. After-tax returns are calculated using historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

The performance information reflects Fund expenses, and assumes that all distributions have been reinvested. Each Index is an unmanaged index, has no expenses, and it is not possible to invest directly in an index. Updated performance information is available at the Fund's website at www.sitfunds.com or by calling 800-332-5580.
