Management's Discussion of Fund Performance

The performance of the Fund for the period presented is shown in the Average Annual Total Returns table.

Top Performance Contributors

Stock selection| Selections in the consumer discretionary, energy and industrials sectors boosted the Fund's relative performance most during the annual period.

Allocations| Larger allocations to the industrials and health care sectors and smaller allocations to the financials and communication services sectors buoyed the Fund's relative performance during the annual period.

Individual holdings| Positions in Celestica Inc., an electronic component manufacturer; Exact Sciences Corporation, a cancer screening and diagnostics company; Aerovironment Inc., a robotics systems developer; Curtiss-Wright Corporation, which builds high-precision parts for airplanes, the military, and nuclear power systems; and Coherent Corp., which makes lasers, optical parts, and high tech materials, were among the top contributors to the Fund's relative performance.

Top Performance Detractors

Stock selection| Selections in the health care, information technology, financials and consumer staples sectors hurt the Fund's relative performance during the annual period.

Allocations| A large weighting in the consumer staples sector and a small allocation to the utilities sector detracted from the Fund's relative performance.

Individual holdings| Fund positions in Globant SA, which helps organizations build modern digital technology like apps, websites, AI systems, and software; Parsons Corporation, a developer of national security and cybersecurity systems to protect roads, bridges, airports, and water systems; Glaukos Corp., a medical technology and pharmaceutical company; Credo Technology Group, a developer of connectivity solutions; and Blue Owl Capital, an asset management firm, were top detractors from the Fund's relative performance during the period.

Notes to Portfolio of Investments
(a)
Non-income producing investment.
(b)
Represents fair value as determined in good faith under procedures approved by the Board of Trustees. At December 31, 2025, the total value of these securities amounted to $200,783, which represents 0.04% of total net assets.
(c)
Denotes a restricted security, which is subject to legal or contractual restrictions on resale under federal securities laws. Disposal of a restricted investment may involve time-consuming negotiations and expenses, and prompt sale at an acceptable price may be difficult to achieve. Private placement securities are generally considered to be restricted, although certain of those securities may be traded between qualified institutional investors under the provisions of Section 4(a)(2) and Rule 144A. The Fund will not incur any registration costs upon such a trade. These securities are valued at fair value determined in good faith under consistently applied procedures approved by the Fund's Board of Trustees. At December 31, 2025, the total market value of these securities amounted to $200,783, which represents 0.04% of total net assets. Additional information on these securities is as follows:

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.

Fair value measurements  (continued)
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. 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 any fees and expenses imposed under your Contract and/or Qualified Plan, as applicable; such fees and expenses would reduce the total returns for all periods shown. 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 Highlights
(a)
Had the Investment Manager and/or its affiliates not waived a portion of expenses, total return would have been reduced.
(b)
In addition to the fees and expenses that the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of any other funds in which it invests. Such indirect expenses are not included in the Fund's reported expense ratios.
(c)
Ratios include 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. If these had been excluded, expenses would have been higher by 0.01%.
(d)
Total net expenses include the impact of certain fee waivers/expense reimbursements made by the Investment Manager and certain of its affiliates, if applicable.

Notes to Financial Statements December 31, 2025
Note 1. Organization
Columbia Variable Portfolio - Acorn Fund (formerly known as Wanger Acorn) (the Fund), a series of Columbia Funds Variable Series Trust (formerly known as Wanger Advisors 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 Massachusetts business trust.
Effective June 1, 2025, the Fund was renamed Columbia Variable Portfolio - Acorn Fund and the Trust was renamed Columbia Funds Variable Series Trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers shares to separate accounts funding variable annuity contracts and variable life insurance policies (collectively, Contracts) issued by affiliated and unaffiliated life insurance companies (Participating Insurance Companies) as well as qualified pension and retirement plans (Qualified Plans) and other qualified institutional investors (Qualified Investors) authorized by Columbia Management Investment Distributors, Inc. (the Distributor). You may not buy (nor will you own) shares of the Fund directly. You may invest by participating in a Qualified Plan or by buying a Contract and making allocations to the Fund.
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. Prior to July 7, 2025, the chief operating decision maker (CODM) was Columbia Wanger Asset Management, LLC (CWAM), a wholly-owned subsidiary of Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Effective July 7, 2025, Columbia Management is the CODM. The CODM, through its Investment Oversight Committee and Global Executive Group, is 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
Equity securities listed on an exchange are valued at the closing price or last trade price on their primary exchange at the close of business of the New York Stock Exchange. Securities with a closing price not readily available or not listed on any exchange are valued at the mean between the closing bid and ask prices. Listed preferred stocks convertible into common stocks are valued using an evaluated price from a pricing service.
12
Columbia Variable Portfolio - Acorn Fund  | 2025
Notes to Financial Statements (continued) December 31, 2025
Foreign equity securities are valued based on the closing price or last trade price on their primary exchange at the close of business of the New York Stock Exchange. If any foreign equity security closing prices are not readily available, the securities are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets. Foreign currency exchange rates are determined at the scheduled closing time of the New York Stock Exchange. Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. In those situations, foreign securities will be fair valued pursuant to a policy approved by the Board of Trustees. Under the policy, the Fund may utilize a third-party pricing service to determine these fair values. The third-party pricing service takes into account multiple factors, including relevant general and sector indices, currency fluctuations, depositary receipts, and futures, as applicable, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the New York Stock Exchange. The fair value of a security is likely to be different from the quoted or published price, if available.
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.
Securities lending
Effective November 30, 2025, the security lending program was terminated and any outstanding loans were recalled on or before the effective date. The Fund, prior to November 30, 2025, had the ability to lend securities up to one-third of the value of its total assets to certain approved brokers, dealers, banks or other institutional borrowers of securities that the Fund's securities lending agent had determined were credit worthy under guidelines established by the Board of Trustees, to earn additional income. The Fund retained the benefits of owning the securities, including the economic equivalent of dividends or interest generated by the security. The Fund also received a fee for the loan. The Fund had the ability to recall the loans at any time and could do so in order to vote proxies or to sell the loaned securities. Each loan was collateralized by cash that exceeded the value of the securities on loan. The market value of the loaned securities was determined daily at the close of business of the Fund and any additional required collateral was delivered to the Fund on the next business day. The Fund elected to invest the cash collateral in the Dreyfus Government Cash Management Fund, a third-party institutional government money market fund in accordance with investment guidelines contained in the securities lending agreement and approved by the Board of Trustees. The income earned from the securities lending program was paid to the Fund, net of any fees remitted to Goldman Sachs Agency Lending, the Fund's lending agent, and borrower rebates. The Investment Manager did not retain any fees earned by the lending program. The net lending income earned by the Fund for the year ended December 31, 2025, is included in the Statement of Operations.
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
Corporate actions and dividend income are generally recorded net of any non-reclaimable tax withholdings, on the ex-dividend date or upon receipt of an ex-dividend notification in the case of certain foreign securities.

Notes to Financial Statements (continued) December 31, 2025
The Fund may receive distributions from holdings in equity securities, business development companies (BDCs), exchange-traded funds (ETFs), limited partnerships (LPs), other regulated investment companies (RICs), and real estate investment trusts (REITs), which report information as to the tax character of their distributions annually. These distributions are allocated to dividend income, capital gain and return of capital based on actual information reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. With respect to REITs, to the extent actual information has not yet been reported, estimates for return of capital are made by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). The Investment Manager's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs, which could result in a proportionate change in return of capital to shareholders.
Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities on the payment date, the proceeds are recorded as realized gains.
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.
Determination of net asset value
The net asset value per share of the Fund is computed by dividing the value of the net assets of the Fund by the total number of outstanding shares of the Fund, rounded to the nearest cent, at the close of regular trading (ordinarily 4:00 p.m. Eastern Time) every day the New York Stock Exchange is open.
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, because the Fund meets the exception under Internal Revenue Code Section 4982(f), the Fund expects not to 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 subaccounts
Distributions to the subaccounts of Contracts, Qualified Plans and Qualified Investors are recorded at the close of business on the record date and are payable on the first business day following the record date. Dividends from net investment income, if any, are declared and distributed semi-annually. Capital gain distributions, when available, will be made annually. However, an additional capital gain distribution may be made during the fiscal year in order to comply with the Internal Revenue Code, as applicable to registered investment companies. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP. All dividends and distributions are reinvested in additional shares of the applicable share class of the Fund at the net asset value as of the ex-dividend date of the distribution.

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
Prior to July 7, 2025, CWAM furnished investment supervision to the Fund and was responsible for the overall management of the Fund's business affairs.
Prior to April 1, 2025, CWAM furnished investment advisory services to the Fund under an investment advisory agreement (the Advisory Agreement) and provided administrative services to the Fund under a separate administrative services agreement (the Administration Agreement). Effective April 1, 2025, the Fund entered into a new management services agreement (the Management Agreement) that combined the management services fee that was previously paid under the Advisory Agreement with the administrative services fee that was previously paid under the Administration Agreement. On June 26, 2025, the Fund's Board of Trustees approved a Novation of Management Agreement pursuant to which all rights, duties and obligations under the Fund's then-current Management Agreement with CWAM transferred to its parent company Columbia Management on July 7, 2025. Prior to July, 7, 2025, Columbia Management was the sub-administrator of the Fund and the investment adviser of each of the other Columbia funds except for Columbia Variable Portfolio - Acorn International Fund and each series of Columbia Acorn Trust. The services provided to, and management fees paid by, the Fund did not change as a result of this transfer and the current portfolio managers of the Fund continued to manage the Fund after the transition.
For the period from January 1, 2025 through February 28, 2025, CWAM received an advisory fee that was equal to a percentage of the Fund's daily net assets that declined from 0.74% to 0.63% as the Fund's net assets increased. The annualized effective advisory fee rate for the period from January 1, 2025 through February 28, 2025 was 0.74% of the Fund's average daily net assets.
Effective March 1, 2025, the Board of Trustees approved a reduction in the advisory fee rates payable to CWAM by the Fund. For the period March 1, 2025 through March 31, 2025 CWAM received an advisory fee that was equal to a percentage of the Fund's daily net assets that declined from 0.74% to 0.61% as the Fund's net assets increased. The annualized effective advisory fee rate for the period from March 1, 2025 through March 31, 2025 was 0.74% of the Fund's average daily net assets. Advisory fees paid by the Fund for the period January 1, 2025 through March 31, 2025 are included in Management services fees on the Statement of Operations.
For the period April 1, 2025 through December 31, 2025, the Investment Manager (CWAM prior to July 7, 2025 and Columbia Management beginning July 7, 2025) received a management services fee that was equal to a percentage of the Fund's daily net assets that declined from 0.79% to 0.63% as the Fund's net assets increased. The annualized effective management services fee rate for the period April 1, 2025 through December 31, 2025 was 0.79% of the Fund's average daily net assets.
For the period January 1, 2025 through December 31, 2025, the effective blended advisory fee (for the period January 1, 2025 through March 31, 2025) and management services fee (for the period April 1, 2025 through December 31, 2025) was 0.78% of the Fund's average daily net assets.

For the period January 1, 2025 through March 31, 2025, the annualized effective administration fee rate was 0.05% 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.
Service fees
The Fund has entered into a Shareholder Services Agreement with Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial. Under this agreement, the Fund pays a service fee equal to the payments made by the Transfer Agent to Participating Insurance Companies and other financial intermediaries (together, Participating Organizations) for services each such Participating Organization provides to its clients, customers and participants that are invested directly or indirectly in the Fund, up to a cap approved by the Board of Trustees from time to time. The effective service fee rate for the year ended December 31, 2025 was 0.12% of the Fund's average daily net assets.
The Transfer Agent may retain as compensation for its services revenues from fees for wire, telephone and redemption orders, account transcripts due to the Transfer Agent from Fund shareholders and interest (net of bank charges) earned with respect to balances in accounts the Transfer Agent maintains in connection with its services to the Fund.
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) indefinitely, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund's net operating expenses, 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 annual rate of 0.91% of the Fund's average daily net assets for the period March 1, 2025 through April 30, 2027. Prior to March 1, 2025, it did not exceed the annual rate of 0.95 of the Fund's average daily net assets.
16
Columbia Variable Portfolio - Acorn Fund  | 2025
Notes to Financial Statements (continued) December 31, 2025
Under the agreement governing this fee waiver and/or expense reimbursement arrangement, 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. 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 December 31, 2025, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, passive foreign investment company (pfic) holdings, capital loss carryforwards, trustees' deferred compensation, net operating loss reclassification and miscellaneous adjustments. 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:

2,411,459
(42,124

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 $367,458,718 and $439,488,341, respectively, for the year ended December 31, 2025. 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 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. 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 December 31, 2025.

Columbia Variable Portfolio - Acorn Fund  | 2025
Notes to Financial Statements (continued) December 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 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, 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 December 31, 2025, one unaffiliated shareholder of record owned 22.7% 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. Affiliated shareholders of record owned 53.2% 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 9. 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 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.

We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Variable Portfolio - Acorn Fund (one of the funds constituting Columbia Funds Variable Series Trust, referred to hereafter as the "Fund") as of December 31, 2025, the related statement of operations for the year ended December 31, 2025, the statement of changes in net assets for each of the two years in the period ended December 31, 2025, including the related notes, and the financial highlights for each of the five years in the period ended December 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 December 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 December 31, 2025 and the financial highlights for each of the five years in the period ended December 31, 2025 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 December 31, 2025 by correspondence with the custodian, transfer agent and issuer of a privately offered security. We believe that our audits provide a reasonable basis for our opinion.

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 accompanying Notes to Financial Statements are an integral part of this statement.

Columbia Variable Portfolio - Acorn International Fund  | 2025
Portfolio of Investments (continued) December 31, 2025
Fair value measurements  (continued)
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.
Values of foreign equity securities actively traded in markets where there is a significant delay in the local close relative to the New York Stock Exchange may include an adjustment to reflect the impact of market movements following the close of local trading, as described in Note 2 to the financial statements - Security valuation. When such adjustments have been made, the foreign equity securities are classified as Level 2.
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 Fund's assets assigned to the Level 2 input category are generally valued using the market approach, in which a security's value is determined through reference to prices and information from market transactions for similar or identical assets. These assets include certain foreign securities for which a third party statistical pricing service may be employed for purposes of fair market valuation. The model utilized by such third party statistical pricing service takes into account a security's correlation to available market data including relevant general and sector indices, currency fluctuations, depositary receipts, and futures, as applicable.

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 any fees and expenses imposed under your Contract and/or Qualified Plan, as applicable; such fees and expenses would reduce the total returns for all periods shown. 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%.

Columbia Variable Portfolio - Acorn International Fund  | 2025
Notes to Financial Statements December 31, 2025
Note 1. Organization
Columbia Variable Portfolio - Acorn International Fund (formerly known as Wanger International) (the Fund), a series of Columbia Funds Variable Series Trust (formerly known as Wanger Advisors 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 Massachusetts business trust.
Effective June 1, 2025, the Fund was renamed Columbia Variable Portfolio - Acorn International Fund and the Trust was renamed Columbia Funds Variable Series Trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers shares to separate accounts funding variable annuity contracts and variable life insurance policies (collectively, Contracts) issued by affiliated and unaffiliated life insurance companies (Participating Insurance Companies) as well as qualified pension and retirement plans (Qualified Plans) and other qualified institutional investors (Qualified Investors) authorized by Columbia Management Investment Distributors, Inc. (the Distributor). You may not buy (nor will you own) shares of the Fund directly. You may invest by participating in a Qualified Plan or by buying a Contract and making allocations to the Fund.
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. Prior to July 7, 2025, the chief operating decision maker (CODM) was Columbia Wanger Asset Management, LLC (CWAM), a wholly-owned subsidiary of Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Effective July 7, 2025, Columbia Management is the CODM. The CODM, through its Investment Oversight Committee and Global Executive Group, is 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
Equity securities listed on an exchange are valued at the closing price or last trade price on their primary exchange at the close of business of the New York Stock Exchange. Securities with a closing price not readily available or not listed on any exchange are valued at the mean between the closing bid and ask prices. Listed preferred stocks convertible into common stocks are valued using an evaluated price from a pricing service.
Columbia Variable Portfolio - Acorn International Fund  | 2025

Notes to Financial Statements (continued) December 31, 2025
Foreign equity securities are valued based on the closing price or last trade price on their primary exchange at the close of business of the New York Stock Exchange. If any foreign equity security closing prices are not readily available, the securities are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets. Foreign currency exchange rates are determined at the scheduled closing time of the New York Stock Exchange. Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. In those situations, foreign securities will be fair valued pursuant to a policy approved by the Board of Trustees. Under the policy, the Fund may utilize a third-party pricing service to determine these fair values. The third-party pricing service takes into account multiple factors, including relevant general and sector indices, currency fluctuations, depositary receipts, and futures, as applicable, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the New York Stock Exchange. The fair value of a security is likely to be different from the quoted or published price, if available.
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.
Foreign currency transactions and translations
The values of all assets and liabilities denominated in foreign currencies are generally translated into U.S. dollars at exchange rates determined at the close of regular trading on the New York Stock Exchange. Net realized and unrealized gains (losses) on foreign currency transactions and translations include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.
For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments in the Statement of Operations.
Securities lending
Effective November 30, 2025, the security lending program was terminated and any outstanding loans were recalled on or before the effective date. The Fund, prior to November 30, 2025, had the ability to lend securities up to one-third of the value of its total assets to certain approved brokers, dealers, banks or other institutional borrowers of securities that the Fund's securities lending agent had determined were credit worthy under guidelines established by the Board of Trustees, to earn additional income. The Fund retained the benefits of owning the securities, including the economic equivalent of dividends or interest generated by the security. The Fund also received a fee for the loan. The Fund had the ability to recall the loans at any time and could do so in order to vote proxies or to sell the loaned securities. Each loan was collateralized by cash that exceeded the value of the securities on loan. The market value of the loaned securities was determined daily at the close of business of the Fund and any additional required collateral was delivered to the Fund on the next business day. The Fund elected to invest the cash collateral in the Dreyfus Government Cash Management Fund, a third-party institutional government money market fund in accordance with investment guidelines contained in the securities lending agreement and approved by the Board of Trustees. The income earned from the securities lending program was paid to the Fund, net of
12
Columbia Variable Portfolio - Acorn International Fund  | 2025
Notes to Financial Statements (continued) December 31, 2025
any fees remitted to Goldman Sachs Agency Lending, the Fund's lending agent, and borrower rebates. The Investment Manager did not retain any fees earned by the lending program. The net lending income earned by the Fund for the year ended December 31, 2025, is included in the Statement of Operations.
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
Corporate actions and dividend income are generally recorded net of any non-reclaimable tax withholdings, on the ex-dividend date or upon receipt of an ex-dividend notification in the case of certain foreign securities.
The Fund may receive distributions from holdings in equity securities, business development companies (BDCs), exchange-traded funds (ETFs), limited partnerships (LPs), other regulated investment companies (RICs), and real estate investment trusts (REITs), which report information as to the tax character of their distributions annually. These distributions are allocated to dividend income, capital gain and return of capital based on actual information reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. With respect to REITs, to the extent actual information has not yet been reported, estimates for return of capital are made by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). The Investment Manager's estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs, which could result in a proportionate change in return of capital to shareholders.
Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities on the payment date, the proceeds are recorded as realized gains.
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.
Determination of net asset value
The net asset value per share of the Fund is computed by dividing the value of the net assets of the Fund by the total number of outstanding shares of the Fund, rounded to the nearest cent, at the close of regular trading (ordinarily 4:00 p.m. Eastern Time) every day the New York Stock Exchange is open.
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, because the Fund meets the exception under Internal Revenue Code Section 4982(f), the Fund expects not to 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.
Columbia Variable Portfolio - Acorn International Fund  | 2025

Notes to Financial Statements (continued) December 31, 2025
Distributions to subaccounts
Distributions to the subaccounts of Contracts, Qualified Plans and Qualified Investors are recorded at the close of business on the record date and are payable on the first business day following the record date. Dividends from net investment income, if any, are declared and distributed semi-annually. Capital gain distributions, when available, will be made annually. However, an additional capital gain distribution may be made during the fiscal year in order to comply with the Internal Revenue Code, as applicable to registered investment companies. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP. All dividends and distributions are reinvested in additional shares of the applicable share class of the Fund at the net asset value as of the ex-dividend date of the distribution.
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
Prior to July 7, 2025, CWAM furnished investment supervision to the Fund and was responsible for the overall management of the Fund's business affairs.
Prior to April 1, 2025, CWAM furnished investment advisory services to the Fund under an investment advisory agreement (the Advisory Agreement) and provided administrative services to the Fund under a separate administrative services agreement (the Administration Agreement). Effective April 1, 2025, the Fund entered into a new management services agreement (the Management Agreement) that combined the management services fee that was previously paid under the Advisory Agreement with the administrative services fee that was previously paid under the Administration Agreement. On June 26, 2025, the Fund's Board of Trustees approved a Novation of Management Agreement pursuant to which all rights, duties and obligations under the Fund's then-current Management Agreement with CWAM transferred to its parent company Columbia Management on July 7, 2025. Prior to July, 7, 2025, Columbia Management was the sub-administrator of the Fund and the investment adviser of each of the other Columbia funds except for Columbia Variable Portfolio - Acorn Fund and each series of Columbia Acorn Trust. The services provided to, and management fees paid by, the Fund did not change as a result of this transfer and the current portfolio managers of the Fund continued to manage the Fund after the transition.
For the period from January 1, 2025 through February 28, 2025, CWAM received an advisory fee that was equal to a percentage of the Fund's daily net assets that declined from 1.10% to 0.72% as the Fund's net assets increased. The annualized effective advisory fee rate for the period from January 1, 2025 through February 28, 2025 was 0.99% of the Fund's average daily net assets.
Effective March 1, 2025, the Board of Trustees approved a reduction in the advisory fee rates payable to CWAM by the Fund. For the period March 1, 2025 through March 31, 2025 CWAM received an advisory fee that was equal to a percentage of the Fund's daily net assets that declined from 0.87% to 0.70% as the Fund's net assets increased. The annualized effective advisory fee rate for the period from March 1, 2025 through March 31, 2025 was 0.87% of the Fund's average daily net assets. Advisory fees paid by the Fund for the period January 1, 2025 through March 31, 2025 are included in Management services fees on the Statement of Operations.
For the period April 1, 2025 through December 31, 2025, the Investment Manager (CWAM prior to July 7, 2025 and Columbia Management beginning July 7, 2025) received a management services fee that was equal to a percentage of the Fund's daily net assets that declined from 0.92% to 0.72% as the Fund's net assets increased. The annualized effective management services fee rate for the period April 1, 2025 through December 31, 2025 was 0.92% of the Fund's average daily net assets.
14
Columbia Variable Portfolio - Acorn International Fund  | 2025
Notes to Financial Statements (continued) December 31, 2025
For the period January 1, 2025 through December 31, 2025, the effective blended advisory fee (for the period January 1, 2025 through March 31, 2025) and management services fee (for the period April 1, 2025 through December 31, 2025) was 0.93% of the Fund's average daily net assets.
Participating Affiliates
The Investment Manager and its investment advisory affiliates (Participating Affiliates), may coordinate in providing services to their clients. These Participating Affiliates, like the Investment Manager, are direct or indirect subsidiaries of Ameriprise Financial and are registered with the appropriate respective regulators and, where required, the Securities and Exchange Commission and the Commodity Futures Trading Commission in the United States. The Investment Manager engages employees of Participating Affiliates to provide portfolio management services to the Fund. These employees provide services to the Investment Manager pursuant to personnel-sharing agreements or other inter-company arrangements and the Fund pays no additional fees and expenses as a result of any such arrangements.
Specifically, pursuant to such arrangements, employees of Participating Affiliates serve as "associated persons" of the Investment Manager and, in this capacity, serve as Fund portfolio managers and provide portfolio management services to the Fund on behalf of the Investment Manager subject to the oversight and supervision of the Investment Manager and the Fund's Chief Compliance Officer, consistent with the investment objectives, policies and limitations set forth in the Fund's prospectus and SAI, and the Investment Manager's and the Fund's compliance policies and procedures.
Administration fees
Prior to April 1, 2025, CWAM received an administration fee from the Fund at the following annual rates:
Aggregate average daily net assets of the Trust
Annual
fee rate
Up to $4 billion
0.05%
$4 billion to $6 billion
0.04%
$6 billion to $8 billion
0.03%
$8 billion and over
0.02%
For the period January 1, 2025 through March 31, 2025, the annualized effective administration fee rate was 0.05% 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.
Service fees
The Fund has entered into a Shareholder Services Agreement with Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial. Under this agreement, the Fund pays a service fee equal to the payments made by the Transfer Agent to Participating Insurance
Columbia Variable Portfolio - Acorn International Fund  | 2025
15
Notes to Financial Statements (continued) December 31, 2025
Companies and other financial intermediaries (together, Participating Organizations) for services each such Participating Organization provides to its clients, customers and participants that are invested directly or indirectly in the Fund, up to a cap approved by the Board of Trustees from time to time. The effective service fee rate for the year ended December 31, 2025 was 0.12% of the Fund's average daily net assets.
The Transfer Agent may retain as compensation for its services revenues from fees for wire, telephone and redemption orders, account transcripts due to the Transfer Agent from Fund shareholders and interest (net of bank charges) earned with respect to balances in accounts the Transfer Agent maintains in connection with its services to the Fund.
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) through April 30, 2027, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund's net operating expenses, 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 annual rate of 1.08% of the Fund's average daily net assets for the period March 1, 2025 through April 30, 2027. Prior to March 1, 2025, it did not exceed the annual rate of 1.14% of the Fund's average daily net assets.
Under the agreement governing this fee waiver and/or expense reimbursement arrangement, 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. 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 December 31, 2025, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, passive foreign investment company (pfic) holdings, capital loss carryforwards, trustees' deferred compensation, foreign currency transactions, distribution reclassifications and foreign capital gains tax. 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:

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.

The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $80,115,676 and $107,519,396, respectively, for the year ended December 31, 2025.

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 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. 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.

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 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, 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 December 31, 2025, affiliated shareholders of record owned 58.3% 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
18

Notes to Financial Statements (continued) December 31, 2025
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 and noted no items requiring adjustment of the financial statements or additional disclosure.
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.

To the Board of Trustees of Columbia Funds Variable Series Trust and Shareholders of Columbia Variable Portfolio - Acorn International Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Variable Portfolio - Acorn International Fund (one of the funds constituting Columbia Funds Variable Series Trust, referred to hereafter as the "Fund") as of December 31, 2025, the related statement of operations for the year ended December 31, 2025, the statement of changes in net assets for each of the two years in the period ended December 31, 2025, including the related notes, and the financial highlights for each of the five years in the period ended December 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 December 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 December 31, 2025 and the financial highlights for each of the five years in the period ended December 31, 2025 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 December 31, 2025 by correspondence with the custodian and transfer agent. We believe that our audits provide a reasonable basis for our opinion.
