## Management's Discussion of Fund Performance
The performance of Class A shares for the period presented is shown in the Average Annual Total Returns table.

### Top Performance Contributors
**Allocations** \| The Fund benefited most on a relative basis from having exposure to residential mortgage-backed securities, investment-grade corporates, asset-backed securities and commercial mortgage-backed securities. Structured asset sectors are all out-of-benchmark sectors, which contributed to the Fund's relative performance during the annual period. High-yield corporates also contributed to the Fund's relative performance as an out-of-benchmark allocation.

**Security selection** \| Security selection within the investment-grade corporate bond sector was additive to the Fund's performance. Selection within the industrials and financials sub-sectors also contributed to the Fund's relative performance.

### Top Performance Detractors
**Allocations** \| An underweight allocation to the investment-grade corporate bond sector detracted modestly from the Fund's relative performance, as the sector outperformed the benchmark during the annual period. Investment-grade corporate bonds represented the Fund's largest sector underweight, excluding U.S. Treasuries.

**Duration and curve positioning** \| The combination of duration and yield curve positioning had a negative impact on the Fund's relative performance during the annual period. The U.S. Federal Reserve continued easing monetary policy during the period with three 25 basis point cuts resulting in a flattening of the yield curve. However, market volatility and the conflict in Iran have the Fed cautious on future reductions in the fed funds target rate in 2026 due to economic uncertainty and the long-term impact of a potential prolonged war.

## Management's Discussion of Fund Performance
The performance of Class S shares for the period presented is shown in the Average Annual Total Returns table.

### Top Performance Contributors
**Allocations** \| The Fund benefited most on a relative basis from having exposure to residential mortgage-backed securities, investment-grade corporates, asset-backed securities and commercial mortgage-backed securities. Structured asset sectors are all out-of-benchmark sectors, which contributed to the Fund's relative performance during the annual period. High-yield corporates also contributed to the Fund's relative performance as an out-of-benchmark allocation.

**Security selection** \| Security selection within the investment-grade corporate bond sector was additive to the Fund's performance. Selection within the industrials and financials sub-sectors also contributed to the Fund's relative performance.

### Top Performance Detractors
**Allocations** \| An underweight allocation to the investment-grade corporate bond sector detracted modestly from the Fund's relative performance, as the sector outperformed the benchmark during the annual period. Investment-grade corporate bonds represented the Fund's largest sector underweight, excluding U.S. Treasuries.

**Duration and curve positioning** \| The combination of duration and yield curve positioning had a negative impact on the Fund's relative performance during the annual period. The U.S. Federal Reserve continued easing monetary policy during the period with three 25 basis point cuts resulting in a flattening of the yield curve. However, market volatility and the conflict in Iran have the Fed cautious on future reductions in the fed funds target rate in 2026 due to economic uncertainty and the long-term impact of a potential prolonged war.

## Management's Discussion of Fund Performance
The performance of Institutional 2 Class shares for the period presented is shown in the Average Annual Total Returns table.

### Top Performance Contributors
**Allocations** \| The Fund benefited most on a relative basis from having exposure to residential mortgage-backed securities, investment-grade corporates, asset-backed securities and commercial mortgage-backed securities. Structured asset sectors are all out-of-benchmark sectors, which contributed to the Fund's relative performance during the annual period. High-yield corporates also contributed to the Fund's relative performance as an out-of-benchmark allocation.

**Security selection** \| Security selection within the investment-grade corporate bond sector was additive to the Fund's performance. Selection within the industrials and financials sub-sectors also contributed to the Fund's relative performance.

### Top Performance Detractors
**Allocations** \| An underweight allocation to the investment-grade corporate bond sector detracted modestly from the Fund's relative performance, as the sector outperformed the benchmark during the annual period. Investment-grade corporate bonds represented the Fund's largest sector underweight, excluding U.S. Treasuries.

**Duration and curve positioning** \| The combination of duration and yield curve positioning had a negative impact on the Fund's relative performance during the annual period. The U.S. Federal Reserve continued easing monetary policy during the period with three 25 basis point cuts resulting in a flattening of the yield curve. However, market volatility and the conflict in Iran have the Fed cautious on future reductions in the fed funds target rate in 2026 due to economic uncertainty and the long-term impact of a potential prolonged war.

## Management's Discussion of Fund Performance
The performance of Institutional 3 Class shares for the period presented is shown in the Average Annual Total Returns table.

### Top Performance Contributors
**Allocations** \| The Fund benefited most on a relative basis from having exposure to residential mortgage-backed securities, investment-grade corporates, asset-backed securities and commercial mortgage-backed securities. Structured asset sectors are all out-of-benchmark sectors, which contributed to the Fund's relative performance during the annual period. High-yield corporates also contributed to the Fund's relative performance as an out-of-benchmark allocation.

**Security selection** \| Security selection within the investment-grade corporate bond sector was additive to the Fund's performance. Selection within the industrials and financials sub-sectors also contributed to the Fund's relative performance.

### Top Performance Detractors
**Allocations** \| An underweight allocation to the investment-grade corporate bond sector detracted modestly from the Fund's relative performance, as the sector outperformed the benchmark during the annual period. Investment-grade corporate bonds represented the Fund's largest sector underweight, excluding U.S. Treasuries.

**Duration and curve positioning** \| The combination of duration and yield curve positioning had a negative impact on the Fund's relative performance during the annual period. The U.S. Federal Reserve continued easing monetary policy during the period with three 25 basis point cuts resulting in a flattening of the yield curve. However, market volatility and the conflict in Iran have the Fed cautious on future reductions in the fed funds target rate in 2026 due to economic uncertainty and the long-term impact of a potential prolonged war.

(d) All Other Fees include amounts for products and services provided by the principal accountant, other than the services reported in paragraphs (a) through (c) above and typically include SOC-1 reviews.

(e)(1) Audit Committee Pre-Approval Policies and Procedures

The registrant's Audit Committee is required to pre-approve the engagement of the registrant's independent auditors to provide audit and non-audit services to the registrant and non-audit services to its investment adviser (excluding any sub-adviser whose role is primarily portfolio management and is sub-contracted or overseen by another investment adviser (the "Adviser") or any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund (a "Control Affiliate") if the engagement relates directly to the operations and financial reporting of the registrant.

The Audit Committee has adopted a Policy for Engagement of Independent Auditors for Audit and Non-Audit Services (the "Policy"). The Policy sets forth the understanding of the Audit Committee regarding the engagement of the registrant's independent accountants to provide (i) audit and permissible audit-related, tax and other services to the registrant ("Fund Services"); (ii) non-audit services to the registrant's Adviser and any Control Affiliates, that relates directly to the operations and financial reporting of a Fund ("Fund-related Adviser Services"); and (iii) certain other audit and non-audit services to the registrant's Adviser and its Control Affiliates. A service will require specific pre-approval by the Audit Committee if it is to be provided by the Fund's independent auditor; provided, however, that pre-approval of non-audit services to the Fund, the Adviser or Control Affiliates may be waived if certain de minimis requirements set forth in the SEC's rules are met.

Under the Policy, the Audit Committee may delegate pre-approval authority to any pre-designated member or members who are independent board members. The member(s) to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next regular meeting. The Audit Committee's responsibilities with respect to the pre-approval of services performed by the independent auditor may not be delegated to management.

On an annual basis, at a regularly scheduled Audit Committee meeting, the Fund's Treasurer or other Fund officer shall submit to the Audit Committee a schedule of the types of Fund Services and Fund-related Adviser Services that are subject to specific pre-approval. This schedule will provide a description of each type of service that is subject to specific pre-approval, along with total projected fees for each service. The pre-approval will generally cover a one-year period. The Audit Committee will review and approve the types of services and the projected fees for the next one-year period and may add to, or subtract from, the list of pre-approved services from time to time, based on subsequent determinations. This specific approval acknowledges that the Audit Committee is in agreement with the specific types of services that the independent auditor will be permitted to perform and the projected fees for each service.

The Fund's Treasurer or other Fund officer shall report to the Audit Committee at each of its regular meetings regarding all Fund Services or Fund-related Adviser Services provided since the last such report was rendered, including a description of the services, by category, with forecasted fees for the annual reporting period, proposed changes requiring specific pre-approval and a description of services provided by the independent auditor, by category, with actual fees during the current reporting period.

(e)(2) None, or 0%, of the Audit-Related Fees, Tax Fees and All Other Fees paid by the Fund or affiliated entities relating directly to the operations and financial reporting of the Registrant disclosed above were approved by the audit committee pursuant to paragraphs (c)(7)(i)(C) of Rule 2-01 of Regulation S-X (which permits audit committee approval after the start of the engagement with respect to services other than audit, review or attest services, if certain conditions are satisfied).

------

(f) Not applicable.

(g) The aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant and rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant.

(h) The registrant's Audit Committee of the Board of Trustees has considered whether the provision of non-audit services that were rendered to the registrant's adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, is compatible with maintaining the principal accountant's independence.

(i) Not applicable.

(j) Not applicable.

#### Item 5. Audit Committee of Listed Registrants.
Not applicable.

#### Item 6. Investments.
(a) The registrant's "Schedule I – Investments in securities of unaffiliated issuers" (as set forth in 17 CFR 210.12-12) is included in Item 7 of this Form N-CSR.

(b) Not applicable.

**Fair value measurements** 

The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund's assumptions about the information market participants would use in pricing an investment. An investment's level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset's or liability's fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

■

Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.

■

Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

■

Level 3 — Valuations based on significant unobservable inputs (including the Fund's own assumptions and judgment in determining the fair value of investments).

Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment's fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.

Investments falling into the Level 3 category, if any, are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.

The Fund's Board of Trustees (the Board) has designated the Investment Manager, through its Valuation Committee (the Committee), as valuation designee, responsible for determining the fair value of the assets of the Fund for which market quotations are not readily available using valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager's organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. Representatives of Columbia Management Investment Advisers, LLC report to the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

The following table is a summary of the inputs used to value the Fund's investments at March 31, 2026:

Financial Highlights

The following table is intended to help you understand the Fund's financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The ratios of expenses and net investment income are annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund's portfolio turnover rate may be higher. A zero balance may reflect an amount rounding to less than $0.01 or 0.01%.

Notes to Financial Statements

March 31, 2026

Note 1. Organization

Columbia Short Term Bond Fund (the Fund), a series of Columbia Funds Series Trust (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

**Fund shares**

The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust's organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.

As described in the Fund's prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 8 years. Institutional Class, Institutional 2 Class, Institutional 3 Class and Class S shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund's prospectus.

Note 2. Summary of significant accounting policies

**Basis of preparation**

The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, *Financial Services - Investment Companies* (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.

**Segment reporting**

The intent of FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures is to enable investors to better understand an entity's overall performance and to assess its potential future cash flows through improved segment disclosures. The chief operating decision maker (CODM) for the Fund is Columbia Management Investment Advisers, LLC through its Investment Oversight Committee and Global Executive Group, which are responsible for assessing performance and making decisions about resource allocation. The CODM has determined that the Fund has a single operating segment because the CODM monitors the operating results of the Fund as a whole and the Fund's long-term strategic asset allocation is pre-determined in accordance with the terms of its prospectus, based on a defined investment strategy which is executed by the Fund's portfolio managers as a team. The financial information provided to and reviewed by the CODM is consistent with that presented within the Fund's financial statements.

**Security valuation**

Debt securities generally are valued based on prices obtained from pricing services, which are intended to reflect market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized market value, unless this method results in a valuation that management believes does not approximate fair value.

Notes to Financial Statements (continued)

March 31, 2026

Asset- and mortgage-backed securities are generally valued by pricing services, which utilize pricing models that incorporate the securities' cash flow and loan performance data. These models also take into account available market data, including trades, market quotations, and benchmark yield curves for identical or similar securities. Factors used to identify similar securities may include, but are not limited to, issuer, collateral type, vintage, prepayment speeds, collateral performance, credit ratings, credit enhancement and expected life. Asset-backed securities for which quotations are readily available may also be valued based upon an over-the-counter or exchange bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized market value, unless this method results in a valuation that management believes does not approximate fair value.

Investments in open-end investment companies (other than exchange-traded funds (ETFs)), are valued at the latest net asset value reported by those companies as of the valuation time.

Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their principal exchanges or, in the absence of a settlement price, at the mean of the latest quoted bid and ask prices.

Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.

The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.

GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund's Portfolio of Investments.

**Derivative instruments**

The Fund invests in certain derivative instruments, as detailed below, in seeking to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management (hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to sell or terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional exposure of a financial instrument is the nominal or face amount that is used to calculate payments made on that instrument and/or changes in value for the instrument. The notional exposure is a hypothetical underlying quantity upon which payment obligations are computed. Notional exposures provide a gauge for how the Fund may behave given changes in the underlying rate, asset or reference instrument and individual markets. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.

A derivative instrument may suffer a marked-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform its obligations under the contract. The Fund's risk of loss from counterparty credit risk on over-the-counter derivatives is generally expected to be limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central counterparty provides some protection in the case of clearing member default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the primary counterparty credit risk is the risk of failure of the clearinghouse. However, credit risk still exists in exchange-traded and centrally cleared derivatives with respect to any

collateral that is held in a broker's customer accounts. While clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients and such shortfall is remedied by the central counterparty or otherwise, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the clearing broker's customers (including the Fund) by account class, potentially resulting in losses to the Fund.

In connection with certain over-the-counter derivatives, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and foreign exchange forward contracts and contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instruments' payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in bankruptcy, insolvency or other events.

Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or central counterparty for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms for most over-the-counter derivatives are subject to regulatory requirements to exchange variation margin with trading counterparties and may have contract specific margin terms as well. For over-the-counter derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g., $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from the broker or receive interest income on cash collateral pledged to the broker. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

Certain ISDA Master Agreements allow counterparties of over-the-counter derivatives transactions to terminate derivatives contracts prior to maturity in the event the Fund's net asset value declines by a stated percentage over a specified time period or if the Fund fails to meet certain terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet certain terms of the ISDA Master Agreement. In determining whether to exercise such termination rights, the Fund would consider, in addition to counterparty credit risk, whether termination would result in a net liability owed from the counterparty.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.

**Futures contracts**

Futures contracts are exchange-traded and represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought and sold futures contracts to manage its exposure to the securities markets or to movements in interest rates and currency values. A Fund invests in futures contracts as part of its primary investment strategy and/or to equitize its cash flows. Investments in futures contracts may increase or decrease exposure to a particular market. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.

Notes to Financial Statements (continued)

March 31, 2026

Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund generally expects to earn interest income on its margin deposits. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Statement of Assets and Liabilities.

**Effects of derivative transactions in the financial statements**

The following tables are intended to provide additional information about the effect of derivatives on the financial statements of the Fund, including: the fair value of derivatives by risk category and the location of those fair values in the Statement of Assets and Liabilities; and the impact of derivative transactions over the period in the Statement of Operations, including realized and unrealized gains (losses). The derivative instrument schedules following the Portfolio of Investments present additional information regarding derivative instruments outstanding at the end of the period, if any.

Notes to Financial Statements (continued)

March 31, 2026

**Asset- and mortgage-backed securities** 

The Fund may invest in asset-backed and mortgage-backed securities. The maturity dates shown represent the original maturity of the underlying obligation. Actual maturity may vary based upon prepayment activity on these obligations. All, or a portion, of the obligation may be prepaid at any time because the underlying asset may be prepaid. As a result, decreasing market interest rates could result in an increased level of prepayment. An increased prepayment rate will have the effect of shortening the maturity of the security. Unless otherwise noted, the coupon rates presented are fixed rates.

**Delayed delivery securities**

The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a "when-issued" or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.

**To be announced securities** 

The Fund may trade securities on a To Be Announced (TBA) basis. As with other delayed-delivery transactions, a seller agrees to issue a TBA security at a future date. However, the seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms.

In some cases, Master Securities Forward Transaction Agreements (MSFTAs) may be used to govern transactions of certain forward-settling agency mortgage-backed securities, such as delayed-delivery and TBAs, between the Fund and counterparty. The MSFTA maintains provisions for, among other things, initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral relating to such transactions.

**Mortgage dollar roll transactions**

The Fund may enter into mortgage "dollar rolls" in which the Fund sells securities for delivery in the current month and simultaneously contracts with the same counterparty to repurchase similar but not identical securities (same type, coupon and maturity) on a specified future date. These transactions may increase the Fund's portfolio turnover rate. During the roll period, the Fund loses the right to receive principal and interest paid on the securities sold. However, the Fund may benefit because it receives negotiated amounts in the form of reductions of the purchase price for the future purchase plus the interest earned on the cash proceeds of the securities sold until the settlement date of the forward purchase. The Fund records the incremental difference between the forward purchase and sale of each forward roll as a realized gain or loss. Unless any realized gains exceed the income, capital appreciation, and gain or loss due to mortgage prepayments that would have been realized on the securities sold as part of the mortgage dollar roll, the use of this technique may diminish the investment performance of the Fund compared to what the performance would have been without the use of mortgage dollar rolls. Mortgage dollar rolls involve the risk that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the counterparty may default on its obligations. All cash proceeds will be invested in instruments that are permissible investments for the Fund. The Fund identifies cash or liquid securities in an amount equal to the forward purchase price. The Fund does not currently enter into mortgage dollar rolls that are accounted for as financing transactions.

**Security transactions**

Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.

**Income recognition**

Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted. The Fund classifies gains and losses realized on prepayments received on mortgage-backed securities as adjustments to interest income.

Notes to Financial Statements (continued)

March 31, 2026

The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. The Fund may also adjust accrual rates when it becomes probable the full interest will not be collected and a partial payment will be received. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured.

Dividend income is recorded on the ex-dividend date.

The value of additional securities received as an income payment through a payment-in-kind, if any, is recorded as interest income and increases the cost basis of such securities.

**Expenses**

General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.

**Determination of class net asset value**

All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.

**Federal income tax status**

The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.

**Foreign taxes**

The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.

Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability in the Statement of Assets and Liabilities.

**Distributions to shareholders**

Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.

**Guarantees and indemnifications**

Under the Trust's organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund's contracts with its service providers contain general indemnification clauses. The Fund's maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

Note 3. Fees and other transactions with affiliates

**Management services fees**

The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice and is responsible for administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund's daily net assets that declines from 0.43% to 0.28% as the Fund's net assets increase. The effective management services fee rate for the year ended March 31, 2026 was 0.42% of the Fund's average daily net assets.

**Compensation of Board members**

Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. Under a Deferred Compensation Plan (the Deferred Plan), these members of the Board of Trustees may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund's liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Deferred Plan. All amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund. The expense for the Deferred Plan, which includes Trustees' fees deferred during the current period as well as any gains or losses on the Trustees' deferred compensation balances as a result of market fluctuations, is included in "Deferred compensation of board members" in the Statement of Operations.

**Compensation of Chief Compliance Officer**

The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer's total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.

**Transfer agency fees**

Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with SS&C GIDS, Inc. (SS&C GIDS) to serve as sub-transfer agent. The Transfer Agent pays the fees of SS&C GIDS for services as sub-transfer agent and SS&C GIDS is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).

The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund's shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.

The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class. In addition, effective August 1, 2025 through July 31, 2026, Institutional 2 Class shares are subject to a contractual transfer agency fee annual limitation of not more than 0.00% and Institutional 3 Class shares are subject to a contractual transfer agency fee annual limitation of not more than 0.00% of the average daily net assets attributable to each share class. Prior to August 1, 2025, Institutional 2 Class shares were subject to a contractual transfer agency fee annual limitation of not more than 0.02% and Institutional 3 Class shares were subject to a contractual transfer agency fee annual limitation of not more than 0.00% of the average daily net assets attributable to each share class.

Notes to Financial Statements (continued)

March 31, 2026

For the year ended March 31, 2026, the Fund's effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:

---

| | |
|:---|:---|
|  | **Effective rate (%)** |
| Class A | 0.08 |
| Class C | 0.08 |
| Institutional Class | 0.08 |
| Institutional 2 Class | 0.01 |
| Institutional 3 Class | 0.00 |
| Class S | 0.08 |

---

An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class's initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended March 31, 2026, these minimum account balance fees reduced total expenses of the Fund by $920.

**Distribution and service fees**

The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.

Under the Plans, the Fund pays a monthly combined distribution and service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A shares of the Fund. Also under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class C shares of the Fund and a monthly distribution fee to the Distributor at the maximum annual rate of 0.55% of the average daily net assets attributable to Class C shares of the Fund.

**Sales charges (unaudited)**

Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended March 31, 2026, if any, are listed below:

---

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

&nbsp;&nbsp;&nbsp;&nbsp;(a) For purchases made on or after August 1, 2024, this charge is imposed on certain investments of $500,000 or more redeemed within 12 months after purchase, with certain limited exceptions. For purchases made prior to August 1, 2024, this charge is imposed on certain investments of between $1 million and $50 million redeemed within 18 months after purchase, as follows: 1.00% if redeemed within 12 months after purchase, and 0.50% if redeemed more than 12, but less than 18, months after purchase, with certain limited exceptions.

&nbsp;&nbsp;&nbsp;&nbsp;(b) This charge applies to redemptions within 12 months after purchase, with certain limited exceptions.

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, costs associated with shareholder meetings, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes. This arrangement may be revised or discontinued at any time. Reflected in the contractual cap commitment, effective August 1, 2025 through July 31, 2026, is the Transfer Agent's contractual agreement to limit total transfer agency fees to an annual rate of not more than 0.00% for Institutional 2 Class and 0.00% for Institutional 3 Class of the average daily net assets attributable to each share class, unless sooner terminated at the sole discretion of the Board of Trustees. Reflected in the contractual cap commitment, prior to August 1, 2025, is the Transfer Agent's contractual agreement to limit total transfer agency fees to an annual rate of not more than 0.02% for Institutional 2 Class and 0.00% for Institutional 3 Class of the average daily net assets attributable to each share class. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods.

Note 4. Federal tax information

The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.

At March 31, 2026, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, derivative investments, tax straddles, principal and/or interest from fixed income securities, capital loss carryforwards, trustees' deferred compensation and distributions. To the extent these differences were permanent, reclassifications were made among the components of the Fund's net assets. Temporary differences do not require reclassifications.

The following reclassifications were made:

---

| | | |
|:---|:---|:---|
| **Undistributed net** <br>**investment** <br>**income ($)**<br>| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Accumulated** <br>**net realized** <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(loss) ($)**<br>| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Paid in** <br>**capital ($)**<br>|

---

| | | | | | |

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At March 31, 2026, the components of distributable earnings on a tax basis were as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Undistributed** <br>**ordinary income ($)**<br>| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Undistributed** <br>**long-term** <br>**capital gains ($)**<br>| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Capital loss** <br>**carryforwards ($)**<br>| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Net unrealized** <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(depreciation) ($)**<br>|

At March 31, 2026, the cost of all investments for federal income tax purposes along with the aggregate gross unrealized appreciation and depreciation based on that cost was:

---

---

Tax cost of investments and unrealized appreciation/(depreciation) may also include timing differences that do not constitute adjustments to tax basis.

The following capital loss carryforwards, determined at March 31, 2026, may be available to reduce future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code. In addition, for the year ended March 31, 2026, capital loss carryforwards utilized, if any, were as follows:

---

| | | | |
|:---|:---|:---|:---|
| **No expiration** <br>**short-term ($)**<br>| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **No expiration** <br>**long-term ($)**<br>| **Total ($)** | **Utilized ($)** |

---

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management's conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund's federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

Note 5. Portfolio information

The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $1,369,144,467 and $1,184,404,428, respectively, for the year ended March 31, 2026, of which $204,651,397 and $202,434,055, respectively, were U.S. government securities. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.

Note 6. Affiliated money market fund

The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. The Securities and Exchange Commission has adopted amendments to money market fund rules requiring

Columbia Short Term Bond Fund \| 2026

------

Notes to Financial Statements (continued)

March 31, 2026

institutional prime money market funds like the Affiliated MMF to be subject to a discretionary liquidity fee of up to 2% if the imposition of such a fee is determined to be in the best interest of the Affiliated MMF and to a mandatory liquidity fee if daily net redemptions exceed 5% of net assets.

Note 7. Interfund lending

Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.

Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager's relationship with each Participating Fund.

The Fund's activity in the Interfund Program during the year ended March 31, 2026 was as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Borrower or lender** | **Average loan** <br>**balance ($)**<br>| &nbsp;&nbsp;&nbsp; **Weighted average** <br>**interest rate (%)**<br>| &nbsp;&nbsp;&nbsp; **Number of days** <br>**with outstanding loans**<br>|
| Lender | 1900000 | &nbsp;&nbsp;&nbsp;&nbsp;4.53 | &nbsp;&nbsp;&nbsp;&nbsp; 7 |

---

Interest income earned by the Fund is recorded as Interfund lending in the Statement of Operations. The Fund had no outstanding interfund loans at March 31, 2026.

Note 8. Line of credit

The Fund has access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to an October 23, 2025 amendment and restatement, the credit facility, which is an agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits aggregate borrowings up to $750 million. Interest is currently charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the secured overnight financing rate plus 0.10% and (iii) the overnight bank funding rate, plus 1.00% in each case. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in October unless extended or renewed. Prior to the October 23, 2025 amendment and restatement, the Fund had access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. which permitted collective borrowings up to $900 million. Interest was charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the secured overnight financing rate plus 0.10% and (iii) the overnight bank funding rate, plus 1.00% in each case.

The Fund had no borrowings during the year ended March 31, 2026.

Note 9. Risks and uncertainties

An investment in the Fund involves risks, including market risk and concentration risk, among others. The value of the Fund's holdings and the Fund's net asset value may go down. 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.

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,

Columbia Short Term Bond Fund \| 2026

------

Notes to Financial Statements (continued)

March 31, 2026

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.

To the extent that the Fund concentrates its investment in particular issuers, countries, geographic regions, industries or sectors, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of issuers, countries, geographic regions, industries, sectors or investments.

Additional risk factors of the Fund are described more fully in the Fund's Prospectus and Statement of Additional Information.

**Shareholder concentration risk**

At March 31, 2026, affiliated shareholders of record owned 32.3% of the outstanding shares of the Fund in one or more accounts. Fund shares sold to or redeemed by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.

Note 10. Subsequent events

Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.

Note 11. Information regarding pending and settled legal proceedings

Ameriprise Financial and certain of its affiliates are involved, in the normal course of business, in legal proceedings that include regulatory inquiries, arbitration and litigation (including class actions) concerning matters arising in connection with the conduct of their activities as part of a diversified financial services firm. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.

There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, it is inherently difficult to determine whether any loss is probable or even reasonably possible, or to reasonably estimate the amount of any loss that may result from such matters. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief, and may lead to further claims, examinations, adverse publicity or reputational damage, each of which could have a material adverse effect on the consolidated financial condition or results of operations or financial condition of Ameriprise Financial or one or more of its affiliates that provide services to the Fund.

Report of Independent Registered Public Accounting Firm

**To the Board of Trustees of Columbia Funds Series Trust and Shareholders of Columbia Short Term Bond Fund**

***Opinion on the Financial Statements***

We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Short Term Bond Fund (one of the funds constituting Columbia Funds Series Trust, referred to hereafter as the "Fund") as of March 31, 2026, the related statement of operations for the year ended March 31, 2026, the statement of changes in net assets for each of the two years in the period ended March 31, 2026, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of March 31, 2026, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended March 31, 2026 and the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

***Basis for Opinion***

These financial statements are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of March 31, 2026 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

**<u>Overview and Statement</u>**

Item 2 of Form N-CSR, the form used by registered management investment companies to file certified annual and semi-annual shareholder reports, requires a registered management investment company to disclose:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Whether it has adopted a code of ethics that applies to the investment company's principal executive
officer and senior financial officers and, if it has not adopted such a code of ethics, why it has not done so; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Any amendments to, or waivers from, the code of ethics relating to such officers.

The Board of the Columbia Funds ("Columbia Board") has adopted the following Code of Ethics for Principle Executive and Senior Financial Officers (the "Code"), which sets forth the ethical standards to which the Funds holds their principal executive officer and each of its senior financial officers.

This Code should be read and interpreted in conjunction with the *Overview and Implementation of Compliance Program Policy*.

**<u>Policy</u>**

The Board has adopted the Code in order to comply with applicable regulatory requirements as outlined below:

**I.** **Covered Officers/Purpose of the Code** 

This Code applies to the Fund's Principal Executive Officer, Principal Financial Officer, and Principal Accounting Officer or Controller (the "Covered Officers") for the purpose of promoting:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between
personal and professional relationships;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Full, fair, accurate, timely and understandable disclosure in reports and documents that the Fund files with, or
submits to, the SEC, and in other public communications made by the Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Compliance with applicable laws and governmental rules and regulations;

*This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed. This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.* 

*Proprietary and Confidential* 

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The prompt internal reporting of violations of the Code to an appropriate person or persons identified in the
Code; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual or apparent conflicts of interest.

**II.** **Administration of the Code** 

The Board has designated an individual to be primarily responsible for the administration of the Code (the "Code Officer"). In the absence of the Code Officer, his or her designee shall serve as the Code Officer, but only on a temporary basis.

The Board has designated a person who meets the definition of a Chief Legal Officer (the "CLO") for purposes of the Sarbanes-Oxley Act of 2002 and the rules promulgated thereunder as the Fund's CLO. The CLO of the Fund shall assist the Fund's Code Officer in administration of this Code. The Code Officer, in consultation with the CLO, shall be responsible for applying this Code to specific situations (in consultation with Fund counsel, where appropriate) and has the authority to interpret this Code in any particular situation.

**III.** **Managing Conflicts of Interest** 

A "conflict of interest" occurs when a Covered Officer's personal interest interferes with the interests of, or his or her service to, the Fund. For example, a conflict of interest would arise if a Covered Officer, or a member of his or her family, receives improper personal benefits as a result of the Covered Officer's position with the Fund. Certain provisions in the 1940 Act and the rules and regulations thereunder and the Advisers Act and the rules and regulations thereunder govern certain conflicts of interest that arise out of the relationships between Covered Officers and the Fund. If such conflicts are addressed in conformity with applicable provisions of the 1940 Act and the Advisers Act, they will be deemed to have been handled ethically. The Fund's and its Adviser's compliance programs and procedures are designed to prevent, or identify and correct, violations of those provisions. This Code does not, and is not intended to, repeat or replace those programs and procedures, and conduct that is consistent with such programs and procedures falls outside of the parameters of this Code.

Although they do not typically present an opportunity for improper personal benefit, conflicts may arise from, or as a result of, the contractual relationships between the Fund and, as applicable, its Adviser (Columbia Management Investment Advisers, LLC ("CMIA") for the Columbia Funds, administrator, principal underwriter, pricing and bookkeeping agent and/or transfer agent (each, a "Primary Service Provider") of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Fund or for a Primary Service Provider, or for both), be involved in establishing policies and implementing decisions that will have different effects on the Primary Service Providers and the Fund. The participation of the Covered Officers in such activities is inherent in the contractual relationships between the Fund and the Primary Service Providers and is consistent with the performance by the Covered Officers of their duties as officers of the Fund. If such conflicts are addressed in conformity with applicable provisions of the 1940 Act and the Advisers Act, they will be deemed to have been handled ethically. In addition, it is recognized by the Board of the Funds that the Covered Officers also may be officers or employees of one or more other investment companies or organizations affiliated with the sponsor of the Funds covered by other similar codes and that the codes of ethics of those other investment companies or organizations will apply to the Covered Officers acting in such capacities for such other investment companies.

This Code covers general conflicts of interest and other issues applicable to the Funds under the Sarbanes-Oxley Act of 2002. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interests of the Funds. Certain examples of such conflicts of interest follow.

Each Covered Officer must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Not use his or her personal influence or personal relationships improperly to influence investment decisions or
financial reporting by the Fund whereby the Covered Officer, or a member of his or her family, would knowingly benefit personally to the detriment of the Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Not knowingly cause the Fund to take action, or fail to take action, for the individual personal benefit of the
Covered Officer, or a member of his or her family, rather than the benefit of the Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Not use material non-public knowledge of portfolio transactions made
or contemplated for the Fund to trade personally or cause others to trade personally in contemplation of the market effect of such transactions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Report at least annually (or more frequently, as appropriate) known affiliations or other relationships that may
give rise to conflicts of interest with respect to the Fund.

If a Covered Officer believes that he or she has a potential conflict of interest that is likely to materially compromise his or her objectivity or his or her ability to perform the duties of his or her role as a Covered Officer, including a potential conflict of interest that arises out of his or her responsibilities as an officer or employee of one or more Primary Service Providers or other funds, he or she should consult with the Code Officer, the CLO, the Fund's outside counsel, or counsel to the Independent Board Members, as appropriate.

Examples of potential conflicts of interest that may materially compromise objectivity or ability to perform the duties of a Covered Officer and which the Covered Officer should consider discussing with the Code Officer or other appropriate person include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Service as a director on the board of a public or private company or service as a public official;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The receipt of a non-de minimus gift when the gift is in relation to
doing business directly or indirectly with the Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The receipt of entertainment from any company with which the Fund has current or prospective business dealings,
unless such entertainment is business-related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety;

*Proprietary and Confidential* 

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An ownership interest in, or any consulting or employment relationship with, any of the Fund's service
providers, other than the Primary Service Providers or any affiliated person thereof; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A direct or indirect material financial interest in commissions, transaction charges or spreads paid by the Fund
for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer's employment, such as compensation or equity ownership.

**IV.** **Disclosure and Compliance** 

It is the responsibility of each Covered Officer:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To familiarize himself or herself with the disclosure requirements generally applicable to the Fund, as well as
the business and financial operations of the Fund;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To not knowingly misrepresent, and to not knowingly cause others to misrepresent, facts about the Fund to others,
whether within or outside the Fund, including to the Fund's Board, Legal Counsel, Independent Legal Counsel and auditors, and to governmental regulators and self-regulatory organizations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To the extent appropriate within his or her area of responsibility, consult with other officers and employees of
the Fund and the Primary Service Providers with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fund files with, or submits to, the SEC and in other public communications made by the
Fund; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To adhere to and, within his or her area of responsibility, promote compliance with the standards and
restrictions imposed by applicable laws, rules and regulations.

**V.** **Reporting and Accountability by Covered Officers** 

Each Covered Officer must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Upon adoption of the Code or becoming a Covered Officer, acknowledge in writing to the Fund's Board that he
or she has received, read and understands the Code, using the form attached as Appendix A hereto;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Annually thereafter acknowledge in writing to the Fund's Board that he or she has received and read the
Code and believes that he or she has complied with the requirements of the Code, using the form attached as Appendix B hereto;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Not retaliate against any employee or Covered Officer for reports of potential violations that are made in good
faith; and

*Proprietary and Confidential* 

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Notify the Code Officer promptly if he or she knows of any violation, or of conduct that reasonably could be
expected to be or result in a violation, of this Code. Failure to do so is a violation of this Code.

The Fund will follow the policy set forth below in investigating and enforcing this Code:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Code Officer will endeavor to take all appropriate action to investigate any potential violation reported to
him or her;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If, after such investigation, the Code Officer believes that no violation has occurred, the Code Officer will so
notify the person(s) reporting the potential violation, and no further action is required;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Any matter that the Code Officer, upon consultation with the CLO, believes is a violation will be reported by the
Code Officer or the CLO to the Fund's Audit Committee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Fund's Audit Committee will be responsible for granting waivers, as appropriate; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• This Code and any changes to or waivers of the Code will, to the extent required, be disclosed as provided by SEC
rules.

**VI. Other Policies** 

This Code shall be the sole code of ethics adopted by the Fund for the purposes of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms applicable to registered management investment companies thereunder. Insofar as other policies or procedures of the Fund or the Fund's Primary Service Providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superseded by this Code to the extent that they conflict with the provisions of this Code. The Fund's and its Adviser's and principal underwriter's codes of ethics under Rule 17j-1 under the 1940 Act and the more detailed policies and procedures of the Primary Service Providers as set forth in their respect Compliance Manuals are separate requirements applicable to the Covered Officers and are not part of this Code.

**VII. Disclosure of Amendments to the Code** 

Any amendments will, to the extent required, be disclosed in accordance with law.

**VIII. Confidentiality** 

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code or upon advice of counsel, such reports and records shall not be disclosed to anyone other than the Fund's Board, the Covered Officers, the Code Officer, the CLO, the Fund's Primary Service Providers and their affiliates, and outside audit firms, legal counsel to the Fund and legal counsel to the Independent Board Members.

**IX.** **Internal Use** 

The Code is intended solely for the internal use by the Fund and does not constitute an admission, by or on behalf of the Fund, as to any fact, circumstance, or legal conclusion.

The Code Officer or CLO shall report to the Fund's Audit Committee any violations of, or material issues arising under, this Code.
