**Investment Objective**

Multi-Manager Growth Strategies Fund (the Fund) seeks 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 and example below.** 

---

| | |
|:---|:---|
| **Shareholder Fees (fees paid directly from your investment)** | **Shareholder Fees (fees paid directly from your investment)** |
|  | **Class Inst** |
| Maximum sales charge (load) imposed on purchases (as a % of offering price) |  |
| &nbsp;&nbsp;&nbsp; Maximum deferred sales charge (load) imposed on redemptions (as a % of the lower of the original purchase price or current <br> net asset value)<br>|  |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

| | |
|:---|:---|
| **Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)** | **Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)** |
|  | **Class Inst** |
| Management fees<sup>(a)</sup> <br>| 0.77<br> %<br>|
| Distribution and/or service (12b-1) fees | 0.00<br> %<br>|
| Other expenses<sup>(b)</sup> <br>| 0.34<br> %<br>|
| **Total annual Fund operating expenses**<sup>(c)</sup> | 1.11<br> %<br>|
| Less: Fee waivers and/or expense reimbursements<sup>(d)</sup> <br>| &nbsp;&nbsp;&nbsp; (0.39<br> %)<br>|
| **Total annual Fund operating expenses after fee waivers and/or expense reimbursements** | 0.72<br> %<br>|

---

(a) Management fees have been restated to reflect current fees based on current asset levels.

(b) Other expenses have been restated and are based on estimated amounts for the Fund's current fiscal year, taking into consideration changes in the Fund's net assets.

(c) "Total annual Fund operating expenses" include acquired fund fees and expenses (expenses the Fund incurs indirectly through its investments in other investment companies) and may be higher than the ratio of expenses to average net assets shown in the *Financial Highlights* section of this prospectus because the ratio of expenses to average net assets does not include acquired fund fees and expenses.

(d) Columbia Management Investment Advisers, LLC and certain of its affiliates have contractually agreed to waive fees and/or to reimburse expenses (excluding transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses, and infrequent and/or unusual expenses) through July 31, 2026, unless sooner terminated at the sole discretion of the Fund's Board of Trustees. Under this agreement, the Fund's net operating expense, subject to applicable exclusions, will not exceed the annual rate of 0.72% for Class Inst. Any difference in the annual rate relative to the annual rate noted in the last row of the above table (e.g., net expense ratio) are due to applicable exclusions under the agreement.

**Example**

The following 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 illustrates the hypothetical expenses that you would incur over the time periods indicated, and assumes that:

<sup>■</sup>

you invest $10,000 in the class of Fund shares for the periods indicated,

<sup>■</sup>

your investment has a 5% return each year, and

<sup>■</sup>

the Fund's total annual operating expenses remain the same as shown in the *Annual Fund Operating Expenses* table above.

Since the waivers and/or reimbursements shown in the *Annual Fund Operating Expenses* table above expire as indicated in the preceding table, they are only reflected in the 1 year example and the first year of the other examples. Although your actual costs may be higher or lower, based on the assumptions listed above, your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **1 year** | **3 years** | **5 years** | **10 years** |
| **Class Inst** (whether or not shares are redeemed) | &nbsp;&nbsp;&nbsp;&nbsp; $74 | &nbsp;&nbsp;&nbsp;&nbsp; $314 | &nbsp;&nbsp;&nbsp;&nbsp; $574 | &nbsp;&nbsp;&nbsp;&nbsp; $1317 |

---

**Portfolio Turnover**

The Fund may pay 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 52% of the average value of its portfolio.

Multi-Manager Growth Strategies Fund

------

**Principal Investment Strategies**

The Fund invests primarily in common stocks of companies believed to have the potential for long-term growth. The Fund may invest in U.S. and foreign securities, including emerging market securities. The Fund may invest in foreign securities directly or indirectly through depositary receipts. The Fund may from time to time emphasize one or more economic sectors in selecting its investments, including the consumer discretionary and information technology sectors.

The Fund may also invest in exchange-traded funds (ETFs).

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager) serves as the investment manager for the Fund and attempts to achieve the Fund's objective by managing a portion of the Fund's assets and selecting one or more subadvisers to manage other portions of the Fund's assets independently of each other and Columbia Management. The Fund's subadvisers are J.P. Morgan Investment Management Inc. (JPMIM) and Loomis, Sayles & Company, L.P. (Loomis Sayles).

In pursuit of the Fund's objective, the portfolio managers use quantitative analysis to evaluate the relative attractiveness of potential investments.

**Principal Risks**

An investment in the Fund involves risks, including **Market Risk**, **Multi-Adviser Risk**, **Growth Securities Risk**, **Quantitative Models Risk**, and **Sector Risk**, among others. Descriptions of these and other principal risks of investing in the Fund are provided below. *There is no assurance that the Fund will achieve its investment objective and you may lose money*. The value of the Fund's holdings may decline, and the Fund's net asset value (NAV) and share price may go down. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The significance of any specific risk to an investment in the Fund will vary over time depending on the composition of the Fund's portfolio, market conditions, and other factors. You should read all of the risk information below carefully, because any one or more of these risks may result in losses to the Fund.

**Active Management Risk.** Due to its active management, the Fund could underperform its benchmark index and/or other funds with similar investment objectives and/or strategies.

**Allocation Risk.** Because the Fund uses an asset allocation strategy in pursuit of its investment objective, there is a risk that the Fund's allocation among asset classes, investments, managers, strategies and/or investment styles will cause the Fund's shares to lose value or cause the Fund to underperform other funds with similar investment objectives and/or strategies, or that the investments themselves will not produce the returns expected.

**Depositary Receipts Risk.** Depositary receipts are receipts issued by a bank or trust company reflecting ownership of underlying securities issued by foreign companies. Some foreign securities are traded in the form of American Depositary Receipts and/or Global Depositary Receipts. Depositary receipts involve risks similar to the risks associated with investments in foreign securities, including those associated with an issuer's (and any of its related companies') country of organization and places of business operations, which may be related to the particular political, regulatory, economic, social and other conditions or events (including, for example, military confrontations and actions, war, other conflicts, terrorism and disease/virus outbreaks and epidemics) occurring in the country and fluctuations in such country's currency, as well as market risk tied to the underlying foreign company. In addition, holders of depositary receipts may have limited voting rights, may not have the same rights afforded to stockholders of a typical domestic company in the event of a corporate action, such as an acquisition, merger or rights offering, and may experience difficulty in receiving company stockholder communications. There is no guarantee that a financial institution will continue to sponsor a depositary receipt, or that a depositary receipt will continue to trade on an exchange, either of which could adversely affect the liquidity, availability and pricing of the depositary receipt. Changes in foreign currency exchange rates will affect the value of depositary receipts and, therefore, may affect the value of your investment in the Fund.

**Emerging Market Securities Risk.** Securities issued by foreign governments or companies in emerging market countries, such as China, Russia and certain countries in Eastern Europe, the Middle East, Asia, Latin America or Africa, are more likely to have greater exposure to the risks of investing in foreign securities that are described in Foreign Securities Risk. In addition, emerging market countries are more likely to experience instability resulting, for example, from rapid changes or developments in social, political, economic or other conditions. Their economies are usually less mature and their securities markets are typically less developed with more limited trading activity (i.e., lower trading volumes and less liquidity) than more developed countries. Emerging market securities tend to be more volatile, and may be more susceptible to market manipulation, than securities in more developed markets. Many emerging market countries are heavily dependent on international trade and have fewer trading partners, which makes them more sensitive to world commodity prices and economic downturns in other countries, and some have a

Multi-Manager Growth Strategies Fund

------

higher risk of currency devaluations. Due to the differences in the nature and quality of financial information of issuers of emerging market securities, including auditing and financial reporting standards, financial information and disclosures about such issuers may be unavailable or, if made available, may be considerably less reliable than publicly available information about other foreign securities.

**Exchange-Traded Fund (ETF) Risk.** Investments in ETFs have unique characteristics, including, but not limited to, the expense structure and additional expenses associated with investing in ETFs. ETFs are subject to, among other risks, tracking risk and passive and, in some cases, active investment risk. In addition, shareholders bear both their proportionate share of the Fund's expenses, and indirectly the ETF's expenses, incurred through the Fund's ownership of the ETF. Because the expenses and costs of an underlying ETF are shared by its investors, redemptions by other investors in the ETF could result in decreased economies of scale and increased operating expenses for such ETF. The ETFs may not achieve their investment objective. The Fund, through its investment in ETFs, may not achieve its investment objective.

**Foreign Securities Risk.** Investments in or exposure to securities of foreign companies may involve heightened risks relative to investments in or exposure to securities of U.S. companies. Investing in securities of foreign companies subjects the Fund to the risks associated with an issuer's (and any of its related companies') country of organization and places of business operations, including risks related to political, regulatory, economic, social, diplomatic and other conditions or events (including, for example, military confrontations and actions, war, other conflicts, terrorism and disease/virus outbreaks and epidemics) occurring in the country or region, as well as risks associated with less developed custody and settlement practices. Foreign securities may be more volatile and less liquid than securities of U.S. companies, and are subject to the risks associated with potential imposition of economic and other sanctions against a particular foreign country, its nationals or industries or businesses within the country. In addition, foreign governments may impose withholding or other taxes on the Fund's income, capital gains or proceeds from the disposition of foreign securities, which could reduce the Fund's return on such securities. The performance of the Fund may also be negatively affected by fluctuations in a foreign currency's strength or weakness relative to the U.S. dollar, particularly to the extent the Fund invests a significant percentage of its assets in foreign securities or other assets denominated in currencies other than the U.S. dollar.

**Growth Securities Risk.** Growth securities typically trade at a higher multiple of earnings than other types of equity securities. Accordingly, the market values of growth securities may never reach their expected market value and may decline in price. In addition, growth securities, at times, may not perform as well as value securities or the stock market in general, and may be out of favor with investors for varying periods of time. Growth securities may also be sensitive to movements in interest rates.

**Investing in Other Funds Risk.** The Fund's investment in other funds (affiliated and/or unaffiliated funds, including exchange-traded funds (ETFs)) subjects the Fund to the investment performance (positive or negative) and risks of the underlying funds in direct proportion to the Fund's investment therein. In addition, investments in ETFs have unique characteristics, including, but not limited to, the expense structure and additional expenses associated with investing in ETFs. The performance of the underlying funds could be adversely affected if other investors in the same underlying funds make relatively large investments or redemptions in such underlying funds. The Fund, and its shareholders, indirectly bear a portion of the expenses of any funds in which the Fund invests. Due to the expenses and costs of an underlying fund being shared by its investors, redemptions by other investors in the underlying funds could result in decreased economies of scale and increased operating expenses for such underlying funds. The Investment Manager has a conflict of interest in selecting affiliated underlying funds over unaffiliated underlying funds because it receives management fees from affiliated underlying funds, and it has a conflict in selecting among affiliated underlying funds, because the fees paid to it by certain affiliated underlying funds are higher than the fees paid by other affiliated underlying funds. Also, to the extent that the Fund is constrained/restricted from investing (or investing further) in a particular underlying fund for one or more reasons (e.g., underlying fund capacity constraints or regulatory restrictions) or if the Fund chooses to sell its investment in an underlying fund because of poor investment performance or for other reasons, the Fund may have to invest in other underlying funds, including less desirable funds – from a strategy or investment performance standpoint – which could have a negative impact on Fund performance. In addition, Fund performance could be negatively impacted if an appropriate alternate underlying fund is not identified in a timely manner or at all. The underlying funds may not achieve their investment objective. The Fund, through its investment in underlying funds, may not achieve its investment objective.

**Issuer Risk.** An issuer in which the Fund invests or to which it has exposure may perform poorly or below expectations, and the value of its securities may therefore decline, which may negatively affect the Fund's performance. Underperformance of an issuer may be caused by poor management decisions, competitive pressures,

breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, natural disasters, military confrontations and actions, war, other conflicts, terrorism, disease/virus outbreaks, epidemics or other events, conditions and factors which may impair the value of your investment in the Fund.

**Market Risk.** The Fund may incur losses due to declines in the value of one or more securities in which it invests. 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 relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund's ability to price or value hard-to-value assets in thinly traded and closed markets and could cause significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, other conflicts, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.

**Multi-Adviser Risk.** The Fund has multiple advisory firms that each manage a portion of the Fund's net assets on a daily basis. Each adviser makes investment decisions independently from the other adviser(s). It is possible that the security selection process of one adviser will not complement or may conflict or even contradict that of the other adviser(s), including making off-setting trades that have no net effect to the Fund, but which may increase Fund expenses. As a result, the Fund's exposure to a given security, industry, sector or market capitalization could be smaller or larger than if the Fund were managed by a single adviser, which could adversely affect the Fund's performance.

**Quantitative Models Risk.** Quantitative models used by the Fund may not effectively identify purchases and sales of Fund investments and may cause the Fund to underperform other investment strategies. Flaws or errors in the quantitative model's assumptions, design, execution, or data inputs may adversely affect Fund performance. Quantitative models may not perform as expected and may underperform in certain market environments including in stressed or volatile market conditions. There can be no assurance that the use of quantitative models will enable the Fund to achieve its objective.

**Sector Risk.** At times, the Fund may have a significant portion of its assets invested in securities of companies conducting business in a related group of industries within one or more economic sectors, including the consumer discretionary and information technology sectors. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund vulnerable to unfavorable developments in that group of industries or economic sector.

<sup>■</sup>

***Consumer Discretionary Sector.*** The Fund is vulnerable to the particular risks that may affect companies in the consumer discretionary sector. Companies in the consumer discretionary sector are subject to certain risks, including fluctuations in the performance of the overall domestic and international economies, interest rate changes, increased competition and consumer confidence. Performance of such companies may be affected by factors including reduced disposable household income, reduced consumer spending, and changing demographics and consumer tastes.

<sup>■</sup>

***Information Technology Sector.*** The Fund is vulnerable to the particular risks that may affect companies in the information technology sector. Companies in the information technology sector are subject to certain risks, including the risk that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. Performance of such companies may be affected by factors including obtaining and protecting patents (or the failure to do so) and significant competitive pressures, including aggressive pricing of their products or services, new market entrants, competition for market share and short product cycles due to an accelerated rate of technological developments. Such competitive pressures may lead to limited earnings and/or falling profit margins. As a result, the value of their securities may fall or fail to rise. In addition, many information technology sector companies have limited operating histories and prices of these companies' securities historically have been more volatile than other securities, especially over the short term. Some companies in the information technology sector are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action, which could negatively impact the value of their securities.

**Performance Information**

The following bar chart and table show you how the Fund has performed in the past, and can help you understand the risks of investing in the Fund. The bar chart shows how the Fund's Class Inst share performance has varied for each full calendar year shown. The table below the bar chart compares the Fund's returns for the periods shown with a broad measure of market performance, as well as another measure of performance for markets in which the Fund may invest.

The performance of Class Inst shares shown in the table below begins before its inception date. The returns shown for Class Inst shares include the returns of the Fund's Class A shares through January 2, 2017. Additionally, the returns shown in the bar chart include the performance of the Fund's Class A shares through January 2, 2017 (performance of Class Inst shares is shown for all other periods since the Fund no longer offers Class A shares). Class A shares were offered prior to the inception date of the Fund's Class Inst shares but have since been merged into the Fund's Class Inst shares. The after-tax returns shown in the *Average Annual Total Returns* table below are calculated using the highest historical individual U.S. federal marginal income tax rates in effect during the period indicated in the table and do not reflect the impact of state, local or foreign taxes. Your actual after-tax returns will depend on your personal tax situation and may differ from those shown in the table. In addition, the after-tax returns shown in the table do not apply to shares held in tax-advantaged accounts such as 401(k) plans or Individual Retirement Accounts (IRAs).

The Fund's performance prior to July 2025 reflects returns achieved by one or more different subadvisers that managed the Fund according to different principal investment strategies. If the Fund's current subadvisers and strategies had been in place for the prior periods, results shown may have been different.

**The Fund's past performance (before and after taxes) is no guarantee of how the Fund will perform in the future.** Updated performance information can be obtained by calling toll-free 800.345.6611 or visiting columbiathreadneedleus.com.

**Purchase and Sale of Fund Shares**

Fund shares are offered only through certain wrap fee programs sponsored and/or managed by Ameriprise Financial, Inc. or its affiliates.

There is a $100 minimum initial investment and no minimum additional investment.

Generally, you may only exchange a share class of a Multi-Manager Strategies Fund for the same class of shares, if available, of another Multi-Manager Strategies Fund. Please refer to the *Buying, Selling and Exchanging Shares — Exchanging Shares* section of the prospectus for more information on exchangeability.

**Tax Information**

The Fund normally distributes net investment income and net realized capital gains, if any, to shareholders. These distributions are generally taxable to you as ordinary income, qualified dividend income or capital gains, unless you are investing through a tax-advantaged account, such as a 401(k) plan or an IRA. If you are investing through a tax-advantaged account, you may be taxed upon withdrawals from that account.

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies — including Columbia Management Investment Advisers, LLC (the Investment Manager), Columbia Management Investment Distributors, Inc. (the Distributor) and Columbia Management Investment Services Corp. (the Transfer Agent) — may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial advisor to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary's website for more information.
