Investment Objective

Columbia Emerging Markets Consumer ETF (the Fund) seeks investment results that correspond (before fees and expenses) to the price and yield performance of the Dow Jones Emerging Markets Consumer Titans^TM Index (the Index).

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, to financial intermediaries, which are not reflected in the table and example below. If such expenses were reflected, the expenses set forth below would be higher.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management fees(a)	0.49%
Distribution and/or service (12b-1) fees	0.00%
Other expenses	0.00%
Total annual Fund operating expenses	0.49%

(a) Pursuant to the Investment Management Services Agreement with Columbia ETF Trust II on behalf of the Fund, Columbia Management Investment Advisers, LLC pays the operating costs and expenses of the Fund, but not taxes, interest, brokerage expenses, portfolio transaction expenses, and infrequent and/or unusual expenses.

  Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example illustrates the hypothetical expenses that you would incur over the time periods indicated (whether or not shares are redeemed), and assumes that:

■ you invest $10,000 in the Fund for the periods indicated,

■ your investment has a 5% return each year, and

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

Investors may pay brokerage commissions on their purchases and sales of the Fund’s shares, which are not reflected in the example. 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
$50	$157	$274	$616

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 25% of the average value of its portfolio.

Principal Investment Strategies

The Fund is an exchange-traded fund (ETF). The Fund seeks to achieve its investment objective by attempting to replicate the performance of the Index through investments in equity securities, including, but not limited to, common shares traded on local exchanges, American Depositary Receipts (ADRs) and Global Depositary Receipts (GDRs).

Under normal circumstances, the Fund invests at least 80% of its net assets in securities of emerging markets consumer companies which comprise the Index and generally expects to be substantially invested at such times with at least 95% of its net assets invested in these securities. The Index is owned and calculated by S&P Dow Jones Indices LLC (S&P DJI or the Index Provider). “Emerging market” companies are those included in the S&P Emerging BMI (Broad Market Index). The Fund may invest in mid-capitalization (mid cap) companies (i.e., those with market capitalizations between U.S. $2 billion and U.S. $10 billion) as well as large capitalization companies. A substantial portion of the Fund’s assets are denominated in currencies other than the U.S. dollar.

The Index is a free-float adjusted market capitalization-weighted stock market index that measures the performance of 60 leading emerging market companies in the Consumer Discretionary sector, Consumer Staples sector, and Communication Services sector, each as defined by Global Industry Classification System (GICS), with the Index

1 Columbia Emerging Markets Consumer ETF

holding 20 companies in each of the three sectors. Companies are first ranked by float adjusted market capitalization, revenue and net income. A final rank is given per company, calculated by weighting market capitalization rank at 60%, revenue at 20%, and net income at 20%. The top 20 ranked securities in each of three sectors are then selected (a total of 60 names). The market capitalization of Index constituents as of June 30, 2023 ranged from approximately U.S. $1.8 billion to U.S. $405.1 billion. A free-float index is one that only uses freely traded shares in calculating the market capitalization weighting. Market capitalization weighting means each component security is weighted by the issuer’s market capitalization relative to the overall capitalization of the Index.

The Fund intends to replicate the constituent securities of the Index as closely as possible using ADRs, GDRs or ordinary local shares. In certain circumstances when it may not be possible or practicable to fully implement a replication strategy, Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager) may utilize a “representative sampling” strategy whereby the Fund would hold a significant number of the component securities of the Index, but may not track the Index with the same degree of accuracy as would an investment vehicle replicating the entire Index.

The Fund invests in specific countries or geographic regions to approximately the same extent as the Index. The Fund may seek investment exposure to Chinese companies operating in certain sectors using a structure known as a variable interest entity (a VIE), rather than an equity ownership in the Chinese company. The Fund concentrates its investments (i.e., holds 25% or more of its net assets) in a particular industry or group of industries to approximately the same extent that the Index is concentrated. As of March 31, 2023, the Index (and therefore the Fund) was concentrated in the communication services, consumer discretionary and consumer staples sectors.

The Fund may operate as non-diversified when the Index is non-diversified. A non-diversified fund can invest a greater percentage of its assets in the securities of fewer issuers than can a diversified fund.

Principal Risks

An investment in the Fund involves risks, including Emerging Market Securities Risk, Foreign Securities Risk, Geographic Focus Risk, Sector Risk, Focused Portfolio Risk, Market Risk, Passive Investment Risk, and Correlation/Tracking Error 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.

Authorized Participant Concentration Risk. Only an Authorized Participant (as defined below) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants, none of which are or will be obligated to engage in creation or redemption transactions. To the extent that these institutions exit the business or are unable or unwilling to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able or willing to step forward to create or redeem Creation Units, Fund shares may trade at a greater premium or discount between the market price and the NAV of the Fund’s shares and/or wider bid/ask spreads than those experienced by other ETFs. Additionally, the Fund could possibly face trading halts and/or delisting from the Exchange. This risk is heightened in times of market stress, including at both the Fund share level and at the Fund holdings level.

Correlation/Tracking Error Risk. The Fund’s value will generally decline when the performance of the securities within the Index declines. A number of factors may affect the Fund’s ability to achieve a high degree of correlation with the Index, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. In addition, the Fund bears management and other expenses and transaction costs in trading securities or other instruments, which the Index does not bear. The Fund, unlike the Index, is subject to regulatory requirements that can limit the Fund’s investments relative to what the Index can hold. Accordingly, the Fund’s performance will likely fail to match the performance of the Index, after taking expenses into account, as well as regulatory limitations. It is not possible to invest directly in an index.

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

Columbia Emerging Markets Consumer ETF 2

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. To the extent that the exchange price of a depositary receipt differs from the local price of the underlying security used by the Index, the Fund may be prevented from fully achieving its investment objective of tracking the performance of the Index.

Early/Late Close/Trading Halt Risk.  An exchange or market may close early, close late or issue trading halts on specific securities, or the ability to buy or sell certain securities may be restricted, which may result in the Fund being unable to buy or sell these securities. In these circumstances, the Fund may be unable to rebalance and reconstitute its portfolio, may be unable to accurately price its investments, may incur substantial trading losses and/or may be prevented from sufficiently tracking the performance of the Index.

Emerging Market Securities Risk. Securities issued by foreign governments or companies in emerging market countries 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 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.

Focused Portfolio Risk. Because the Fund may invest in a limited number of companies, the Fund as a whole is subject to greater risk of loss if any of those securities decline in price.

Foreign Currency Risk. The performance of the Fund may be materially affected positively or negatively by foreign currency strength or weakness relative to the U.S. dollar, particularly if the Fund invests a significant percentage of its assets in foreign securities or other assets denominated in currencies other than the U.S. dollar.

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. Additionally, the Fund’s foreign investments may trade in markets that may not be open on the same day or at the same time as the Fund, or foreign markets may close after the Fund has calculated its NAV for a given business day, which may cause a difference in the market price of such foreign securities and the value attributed to such securities by the Fund which in turn may result in a greater premium or discount between the market price and the NAV of the Fund's shares and/or wider bid/ask spreads than those experienced by other ETFs.

Geographic Focus Risk. The Fund may be particularly susceptible to risks related to economic, political, regulatory or other events or conditions affecting issuers and countries within the specific geographic regions in which the Fund invests. The Fund’s NAV may be more volatile than the NAV of a more geographically diversified fund.

■ Greater China. The Greater China region consists of Hong Kong, The People's Republic of China and Taiwan, among other countries, and the Fund's investments in the region are particularly susceptible to risks in that region. These economies can be significantly affected by currency fluctuations and increasing competition from other emerging economies. Adverse events in the region will generally have a greater effect on the Fund than if the Fund

3 Columbia Emerging Markets Consumer ETF

were more geographically diversified, which could result in greater volatility in the Fund’s NAV and losses. Markets in the Greater China region can experience significant volatility due to social, economic, regulatory and political uncertainties. Many Chinese companies to which the Fund seeks investment exposure use a structure known as a variable interest entity (a VIE) to address Chinese restrictions on direct foreign investment in Chinese companies operating in certain sectors. The Fund’s investment exposure to VIEs may pose additional risks because the Fund’s investment is in a holding company domiciled outside of China (a Holding Company) whose interests in the business of the underlying Chinese operating company (the VIE) are established through contracts rather than equity ownership. The VIE structure is a longstanding practice in China that, until recently, was not acknowledged by the Chinese government, creating uncertainty over the possibility that the Chinese government might cease to tolerate VIE structures at any time or impose new restrictions on the structure. In such a scenario, the Chinese operating company could be subject to penalties, including revocation of its business and operating license, or the Holding Company could forfeit its interest in the business of the Chinese operating company. Further, in case of a dispute, the remedies and rights of the Fund may be limited, and legal uncertainty may be exploited against the interests of the Fund. Control over a VIE may also be jeopardized if a natural person who holds the equity interest in the VIE breaches the terms of the contractual arrangements, is subject to legal proceedings, or if any physical instruments or property of the VIE, such as seals, business registration certificates, financial data and licensing arrangements (sometimes referred to as “chops”), are used without authorization. In the event of such an occurrence, the Fund, as a foreign investor, may have little or no legal recourse. In addition to the risk of government intervention, investments through a VIE structure are subject to the risk that the China-based company (or its officers, directors, or Chinese equity owners) may breach the contractual arrangements, that Chinese law changes in a way that adversely affects the enforceability of the arrangements, or that the contracts are otherwise not enforceable under Chinese law. In any of these cases, a Fund may suffer significant losses on its investments through a VIE structure with little or no recourse available. Further, the Fund is not a VIE owner/shareholder and cannot exert influence through proxy voting or other means. Foreign companies listed on stock exchanges in the United States, including companies using the VIE structure, could also face delisting or other ramifications for failure to meet the expectations and/or requirements of U.S. regulators. Recently, China has proposed the adoption of rules which would affirm that VIEs are legally permissible, though there remains significant uncertainty over how these rules will operate. Any of these risks could reduce the liquidity and value of the Fund’s investments in Holding Companies or render them valueless. 

Index Methodology and Provider Risk. The Fund seeks performance that corresponds to the performance of the Index. There is no guarantee or assurance that the Index will achieve high, or even positive, returns. The Index may underperform more traditional indices. In turn, the Fund could lose value while other indices or measures of market performance increase in value or performance. In addition, the Fund may be subject to the risk that the Index provider may commit errors in Index computation, construction, reconstitution and rebalancing, despite any Index provider procedures designed to prevent such occurrences and due diligence conducted by the Investment Manager. Errors may result in a negative performance impact to the Fund and its shareholders. The decision of whether to remove a security from the tracking index is made by an independent index provider who is not affiliated with the Fund or the Investment Manager.

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 an investment in the Fund and could result in a greater premium or discount between the market price and the NAV of the Fund's shares and wider bid/ask spreads than those experienced by other ETFs.

■ Mid-Cap Stock Risk. Investments in mid-capitalization companies (mid-cap companies) often involve greater risks than investments in larger, more established companies (larger companies) because mid-cap companies tend to have less predictable earnings and may lack the management experience, financial resources, product diversification and competitive strengths of larger companies, and may be less liquid than the securities of larger companies.

■ Large-Cap Stock Risk. Investments in larger companies may involve certain risks associated with their larger size. For instance, larger companies may be less able to respond quickly to new competitive challenges, such as changes in consumer tastes or innovation from smaller competitors. Also, larger companies are sometimes less able to achieve as high growth rates as successful smaller companies, especially during extended periods of economic expansion.

Liquidity Risk. Liquidity risk is the risk associated with any event, circumstance, or characteristic of an investment or market that negatively impacts the Fund’s ability to sell, or realize the proceeds from the sale of, an investment at a desirable time or price. Liquidity risk may arise because of, for example, a lack of marketability of the investment, which means that when seeking to sell its portfolio investments, the Fund could find that selling is more difficult than anticipated, especially during times of high market volatility. Market participants attempting to sell the same or a similar instrument at the same time as the Fund could exacerbate the Fund’s exposure to liquidity risk. The Fund may have to accept a lower selling price for the holding, sell other liquid or more liquid investments that it might otherwise prefer to hold (thereby increasing the proportion of the Fund’s investments in less liquid or illiquid securities), or forego another more appealing investment opportunity. The liquidity of Fund investments may change significantly over time and certain investments that were liquid when purchased by the Fund may later become illiquid, particularly in times of overall economic distress. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may also adversely affect the liquidity and the price of the Fund's investments. Judgment plays a larger role in valuing illiquid or less liquid investments as compared to valuing liquid or more liquid investments. Price volatility may be higher for illiquid or less liquid investments as a result of, for example, the relatively less frequent pricing of such securities (as compared to liquid or more liquid investments). Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. Overall market liquidity and other factors can lead to an increase in redemptions of creation units, which may negatively impact Fund performance and NAV, including, for example, if the Fund is forced to sell investments in a down market. In certain circumstances, the Fund might not be able to dispose of certain holdings quickly or at fair prices, preventing the Fund from tracking the Index.  Foreign securities can present enhanced liquidity risks, including as a result of less developed custody, settlement or other practices of foreign markets. In addition, in stressed market conditions, the market for Fund shares may become less liquid. Deterioration in the liquidity of Fund shares may adversely impact the liquidity of the Fund's underlying portfolio securities. These adverse impacts on the liquidity of Fund shares and on the liquidity of the Fund's underlying portfolio securities could in turn lead to a greater premium or discount between the market price and the NAV of the Fund's shares and/or wider bid/ask spreads than those experienced by other ETFs.

Market Price Relative to NAV Risk. Shares of the Fund may trade at prices that vary from Fund NAV. Shares of the Fund are listed for trading on the Exchange and are bought and sold in the secondary market at market prices that may differ, in some cases significantly, from their NAV. The NAV of the Fund will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of shares, however, will generally fluctuate in response to changes in NAV, as well as the relative supply of, and demand for, Fund shares on the Exchange. The Investment Manager cannot predict whether Fund shares will trade below, at or above their NAV. Price differences may result because of, among other factors, supply and demand forces in the secondary trading market for Fund shares. It is expected that these forces generally will be closely related to, but not identical to, the same forces influencing the prices of the Fund’s holdings. In this regard, if a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. Different investment strategies or techniques, including those intended to be defensive in nature, including, as examples, stop loss orders to sell an ETF’s shares in the secondary market during negative market events or conditions, such as a “flash crash” or other market disruptions, may not work as intended and may produce significant losses to investors. Investors should consult their financial intermediary prior to using any such investment strategies or techniques, or before investing 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 and could result in a greater premium or discount between the market price and the NAV of the Fund's shares and wider bid/ask spreads than those experienced by other ETFs.

Non-Diversified Fund Risk. The Fund may operate as a non-diversified fund when the Index is non-diversified. A non-diversified fund is permitted to invest a greater percentage of its total assets in the securities of fewer issuers than a diversified fund. This increases the risk that a change in the value of any one investment held by the Fund could

5 Columbia Emerging Markets Consumer ETF

affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, when the Fund operates as a non-diversified fund, the Fund’s value will likely be more volatile than the value of a more diversified fund.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to its Index’s investment exposures. The Fund invests in securities or instruments included in, or believed by the portfolio managers to be representative of, the Index regardless of their investment merits. The Fund does not seek temporary defensive positions when markets decline or appear overvalued.

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 communication services, consumer discretionary and consumer staples sectors. The Fund generally concentrates its investments in issuers conducting business in a related group of industries to approximately the same extent as the Index. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that group of industries or economic sector than funds that invest more broadly. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.

■ Communication Services Sector. The Fund is more susceptible to the particular risks that may affect companies in the communication services sector than if it were invested in a wider variety of companies in unrelated sectors. Companies in the communication services 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 communication services 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.

■ Consumer Discretionary/Staples Sectors. The Fund is more susceptible to the particular risks that may affect companies in the consumer discretionary/staples sectors than if it were invested in a wider variety of companies in unrelated sectors. Companies in the consumer discretionary/staples sectors are subject to certain risks, including fluctuations in the performance of the overall domestic and international economies, interest rate changes, currency exchange rates, 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.

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 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 and the index the Fund seeks to track.

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).

Returns after taxes on distributions and sale of Fund shares are higher than before-tax returns for certain periods shown because they reflect the tax benefit of capital losses realized on the redemption of Fund shares.

Purchase and Sale of Fund Shares

The Fund issues and redeems shares only through Authorized Participants (intermediaries, typically broker-dealers who have executed an agreement with the Fund's distributor that governs transactions in Fund creation units) in large blocks of shares, typically 50,000 shares, called Creation Units. Creation Units are issued and redeemed typically for an in-kind basket of securities. Except when aggregated in Creation Units, the Fund shares are not redeemable securities of the Fund.

Individual shares may only be purchased and sold on secondary markets through a financial intermediary, such as a broker-dealer or a bank. Because the Fund’s shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). You may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the ETF (bid) and the lowest price a seller is willing to accept for shares of the ETF (ask) when buying or selling shares in the secondary market (the bid/ask spread). Recent information, including information regarding the Fund’s NAV, market price, premiums and discounts, and bid/ask spread, is available at columbiathreadneedleus.com/etfs.

Tax Information

The Fund’s distributions are taxable and generally will be taxed as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an IRA, in which case your distributions generally will be taxed when withdrawn from the tax-deferred account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares 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. 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.
