INVESTMENT OBJECTIVE

Sit Large 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)   Redemption Fee (as a percentage of amount redeemed only on shares held for less than 30 days)	2.00%
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	1.00%
Total Annual Fund Operating Expenses	1.00%

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
$102	$319	$553	$1,229

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 9.75% 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 the common stocks of companies with capitalizations of $5 billion or more at the time of purchase.

Sit Investment Associates, Inc. (the “Adviser”) invests in domestic growth-oriented companies it believes exhibit the potential for

superior growth. The Fund focuses on stocks issued by companies with long records of earnings and revenue 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, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the Fund and its investments and potentially increase the risks described herein.

The public health crisis caused by the novel coronavirus disease known as COVID-19 has severely impacted business activity in virtually all economies, markets, and sectors and negatively impacted the value of many financial and other assets. The COVID-19 outbreak has resulted in numerous disruptions, including travel and border restrictions, quarantines, supply chain disruptions, lower consumer demand and general market uncertainty. These events could have a significant impact on the Fund’s performance, as well as the performance and viability of issuers in which it invests. Although vaccines for COVID-19 are becoming more widely available, the full extent and duration of the COVID-19 outbreak and its effects cannot be determined with certainty. Similar consequences could arise as a result of the spread of other infectious diseases.

› 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.

› Large Cap Stock Risk: Stocks of large cap companies as a group could fall out of favor with the market, causing the Fund to underperform investments that focus solely on small- or medium- capitalization stocks.

› 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.

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

› 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.

› 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.

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 the Fund’s benchmark index, which is a broad measure of market performance. 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. The benchmark 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.
