(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 Directors 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.

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
The accompanying Notes to Financial Statements are an integral part of this statement.
Columbia Ultra Short Duration Municipal Bond Fund | 2025

Portfolio of Investments (continued) August 31, 2025
Fair value measurements (continued)
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.

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. For periods ended 2022 and thereafter, 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 August 31, 2025
Note 1. Organization
Columbia Ultra Short Duration Municipal Bond Fund (the Fund), a series of Columbia Funds Series Trust II (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 Massachusetts business 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 shares are offered to the general public for investment. Institutional Class 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.
The Board of Trustees of the Fund approved the conversion of all Advisor Class shares of the Fund to Institutional Class shares of the Fund and the subsequent elimination of Advisor Class shares. Effective on November 22, 2024, Advisor Class shares of the Fund were converted to Institutional Class shares of the Fund. This was a tax-free transaction for existing Advisor Class shareholders.
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
In this reporting period, the Fund adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures (ASU 2023-07). Adoption of the new standard impacted financial statement disclosures only and did not affect the Fund's financial position or its results of operations. The intent of the ASU 2023-07 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.

Columbia Ultra Short Duration Municipal Bond Fund | 2025
Notes to Financial Statements (continued) August 31, 2025
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 characteristicsand 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.
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.
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.
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.
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 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.
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.
Columbia Ultra Short Duration Municipal Bond Fund | 2025
15
Notes to Financial Statements (continued) August 31, 2025
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 net tax-exempt and 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.
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.
Recent accounting pronouncements and regulatory updates
Accounting Standards Update 2023-09 Income Taxes (Topic 740)
In December 2023, the FASB issued Accounting Standards Update No. 2023-09 Income Taxes (Topic 740) Improvements to Income Tax Disclosures. The amendments were issued to enhance the transparency and decision usefulness of income tax disclosures primarily related to rate reconciliation and income taxes paid information. The amendments are effective for annual periods beginning after December 15, 2024, with early adoption permitted. Management expects that the adoption of the amendments will not have a material impact on its financial statements.
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 ManagementAgreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to 0.21% of the Fund's 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
16
Columbia Ultra Short Duration Municipal Bond Fund | 2025
Notes to Financial Statements (continued) August 31, 2025
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.
For the year ended August 31, 2025, 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
0.10
Advisor Class
0.02
(a)
Institutional Class
0.10
(a)
Unannualized.
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 August 31, 2025, these minimum account balance fees reduced total expenses of the Fund by $20.
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 0.15% of the average daily net assets attributable to Class A shares of the Fund. The Fund pays the distribution and/or shareholder services fees for Class A up to the point where the Distributor's expenses are fully recovered.
Columbia Ultra Short Duration Municipal Bond Fund | 2025
17
Notes to Financial Statements (continued) August 31, 2025
Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund's net operating expenses, including indirect expenses of the underlying funds, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund's custodian, do not exceed the following annual rate(s) as a percentage of the classes' average daily net assets:
Fee rate(s) contractual
through
December 31, 2025 (%)
Class A
0.47
Institutional Class
0.32
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. Prior to January 1, 2025, expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds) were included with the waivers and/or expense reimbursement arrangement. 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 August 31, 2025, these differences were primarily due to differing treatment for capital loss carryforwards, trustees' deferred compensation, distributions and re-characterization of distributions for investments. 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

Accumulated
net realized

Net investment income (loss) and net realized gains (losses), as disclosed in the Statement of Operations, and net assets were not affected by this reclassification.

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 $24,924,859 and $44,377,534, respectively, for the year ended August 31, 2025. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. 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 did not borrow or lend money under the Interfund Program during the year ended August 31, 2025.
Note 7. 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
Columbia Ultra Short Duration Municipal Bond Fund | 2025
19
Notes to Financial Statements (continued) August 31, 2025
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 August 31, 2025.
Note 8. 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 NAV 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, 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 August 31, 2025, one unaffiliated shareholder of record owned 64.0% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. 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 9. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued. Other than as noted below, there were no items requiring adjustment of the financial statements or additional disclosure.
20
Columbia Ultra Short Duration Municipal Bond Fund | 2025
Notes to Financial Statements (continued) August 31, 2025
The Board of Trustees of the Fund approved a custody agreement with State Street Bank and Trust Company (State Street). The transition of custody services to State Street is expected to be completed by December, 2026. In addition, the Board approved the engagement by the Investment Manager of State Street as sub-administrator. In such capacity, and subject to the supervision and direction of the Investment Manager, State Street will provide certain sub-administration services to the Fund, including fund accounting and financial reporting services.
Note 10. 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 II and Shareholders of Columbia Ultra Short Duration Municipal Bond Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Ultra Short Duration Municipal Bond Fund (one of the funds constituting Columbia Funds Series Trust II, referred to hereafter as the "Fund") as of August 31, 2025, the related statement of operations for the year ended August 31, 2025, the statement of changes in net assets for each of the two years in the period ended August 31, 2025, including the related notes, and the financial highlights for each of the three years in the period ended August 31, 2025 (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 August 31, 2025, 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 August 31, 2025 and the financial highlights for each of the three years in the period ended August 31, 2025 in conformity with accounting principles generally accepted in the United States of America.
The financial statements of the Fund (i) as of and for the year ended August 31, 2022 and the financial highlights for the year or period indicated therein ended August 31, 2022 (not presented herein, other than the financial highlights) and (ii) as of and for the year ended August 31, 2021 and the financial highlights for the year ended August 31, 2021 (not presented herein, other than the financial highlights) were audited by other auditors whose reports dated October 25, 2022 and October 27, 2021, respectively, expressed unqualified opinions on those financial statements and financial highlights.
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 August 31, 2025 by correspondence with the custodian and broker; when replies were not received from the broker, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Approval of Management Agreement
(Unaudited)
Columbia Management Investment Advisers, LLC (the Investment Manager, and together with its domestic and global affiliates, Columbia Threadneedle Investments), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Ultra Short Duration Municipal Bond Fund (the Fund). Under a management agreement (the Management Agreement), the Investment Manager provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).
On an annual basis, the Fund's Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the Management Agreement. The Investment Manager prepared detailed reports for the Board and its Contracts Committee (including its Contracts Subcommittee) in March, April and June 2025, including reports providing the results of analyses performed by a third-party data provider, Broadridge Financial Solutions, Inc. (Broadridge), and comprehensive responses by the Investment Manager to written requests for information by independent legal counsel to the Independent Trustees (Independent Legal Counsel), to assist the Board in making this determination. In addition, throughout the year, the Board (or its committees or subcommittees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by the Investment Manager addressing the services the Investment Manager provides and Fund performance. The Board also accords appropriate weight to the work, deliberations and conclusions of the various committees (including their subcommittees), such as the Contracts Committee, the Investment Review Committee, the Audit Committee and the Compliance Committee in determining whether to continue the Management Agreement.
The Board, at its June 26, 2025 Board meeting (the June Meeting), considered the renewal of the Management Agreement for an additional one-year term. At the June Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. The Independent Trustees considered such information as they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to approve the continuation of the Management Agreement. Among other things, the information and factors considered included the following:

Information on the investment performance of the Fund relative to the performance of a group of mutual funds determined to be comparable to the Fund by Broadridge, as well as performance relative to one or more benchmarks;

Information on the Fund's management fees and total expenses, including information comparing the Fund's expenses to those of a group of comparable mutual funds, as determined by Broadridge;

The Investment Manager's agreement to contractually limit or cap total operating expenses for the Fund so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund's net assets;

Terms of the Management Agreement;

Descriptions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of transfer agency and shareholder services to the Fund;

Descriptions of various services performed by the Investment Manager under the Management Agreement, including portfolio management and portfolio trading practices;

Information regarding any recently negotiated management fees of similarly-managed portfolios of other institutional clients of the Investment Manager;

Information regarding the resources of the Investment Manager, including information regarding senior management, portfolio managers and other personnel;

Information regarding the capabilities of the Investment Manager with respect to compliance monitoring services;

The profitability to the Investment Manager and its affiliates from their relationships with the Fund; and

Approval of Management Agreement (continued) (Unaudited)

Report provided by the Board's independent fee consultant, JDL Consultants, LLC (JDL).
Following an analysis and discussion of the foregoing, and the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the Management Agreement.
Nature, extent and quality of services provided by the Investment Manager
The Board analyzed various reports and presentations it had received detailing the services performed by the Investment Manager, as well as its history, expertise, resources and relative capabilities, and the qualifications of its personnel.
The Board specifically considered the many developments during recent years concerning the services provided by the Investment Manager. Among other things, the Board noted the organization and depth of the equity and credit research departments. The Board further observed the enhancements to the investment risk management department's processes, systems and oversight over the past several years. The Board also took into account the broad scope of services provided by the Investment Manager to the Fund, including, among other services, investment, risk and compliance oversight. The Board also took into account the information it received concerning the Investment Manager's ability to attract and retain key portfolio management personnel and that it has sufficient resources to provide competitive and adequate compensationto investment personnel.
In connection with the Board's evaluation of the overall package of services provided by the Investment Manager, the Board also considered the nature, quality and range of administrative services provided to the Fund by the Investment Manager, as well as the achievements in 2024 in the performance of administrative services, and noted the various enhancements anticipated for 2025. In evaluating the quality of services provided under the Management Agreement, the Board also took into account the organization and strength of the Fund's and its service providers' compliance programs. The Board also reviewed the financial condition of the Investment Manager and its affiliates and each entity's ability to carry out its responsibilities under the Management Agreement and the Fund's other service agreements.
In addition, the Board discussed the acceptability of the terms of the Management Agreement, noting that no changes were proposed from the form of agreement previously approved. The Board also noted the wide array of legal and compliance services provided to the Fund under the Management Agreement.
After reviewing these and related factors (including investment performance as discussed below), the Board concluded, within the context of their overall conclusions, that the nature, extent and quality of the services provided to the Fund under the Management Agreement supported the continuation of the Management Agreement.
Investment performance
The Board carefully reviewed the investment performance of the Fund, including detailed reports providing the results of analyses performed by each of the Investment Manager, Broadridge and JDL collectively showing, for various periods (including since manager inception): (i) the performance of the Fund, (ii) the Fund's performance relative to peers and benchmarks and (iii) the net assets of the Fund. The Board observed that the Fund's performance for certain periods ranked above median based on information provided by Broadridge.
The Board also reviewed a description of the third-party data provider's methodology for identifying the Fund's peer groups for purposes of performance and expense comparisons.
The Board also considered the Investment Manager's performance and reputation generally. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager, in light of other considerations, supported the continuation of the Management Agreement.

Approval of Management Agreement (continued) (Unaudited)
Comparative fees, costs of services provided and the profits realized by the Investment Manager and its affiliates from their relationships with the Fund
The Board reviewed comparative fees and the costs of services provided under the Management Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by Broadridge and JDL) showing a comparison of the Fund's expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund's contribution to the Investment Manager's profitability.
The Board considered the reports of JDL, which assisted in the Board's analysis of the Funds' performance and expenses and the reasonableness of the Funds' fee rates. The Board accorded particular weight to the notion that a primary objective of the level of fees is to achieve a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with certain exceptions) are generally in line with the current "pricing philosophy" such that Fund total expense ratios, in general, approximate or are lower than the median expense ratios of funds in the same Lipper comparison universe. The Board took into account that the Fund's total expense ratio (after considering proposed expense caps/waivers) was below the peer universe's median expense ratio shown in the reports.
After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the levels of management fees and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.
The Board also considered the profitability of the Investment Manager and its affiliates in connection with the Investment Manager providing management services to the Fund. With respect to the profitability of the Investment Manager and its affiliates, the Independent Trustees referred to information discussing the profitability to the Investment Manager and Ameriprise Financial from managing, operating and distributing the Funds. The Board considered that the profitability generated by the Investment Manager in 2024 had increased from 2023 levels due to a variety of factors, including the increased assets under management of the Funds. It also took into account the indirect economic benefits flowing to the Investment Manager or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Fund should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.
Economies of scale
The Board considered the economies of scale that might be realized as the Fund's net asset level grows and took note of the extent to which Fund shareholders might also benefit from such growth. The Board took into account, however, that the Management Agreement already provides for a relatively low flat fee regardless of the Fund's asset level, and requires Columbia Threadneedle to provide investment advice, as well as administrative, accounting and other services to the Fund.
Conclusion
The Board reviewed all of the above considerations in reaching its decision to approve the continuation of the Management Agreement. In reaching its conclusions, no single factor was determinative.
On June 26, 2025, the Board, including all of the Independent Trustees, determined that fees payable under the Management Agreement were fair and reasonable in light of the extent and quality of services provided and approved the renewal of the Management Agreement.
