INFORMATION STATEMENT

NOTICE REGARDING SUBADVISER

An Important Notice Regarding the Internet Availability of Information Statement is being mailed on or about October 28, 2024. This Information Statement is being made available to shareholders of Multi-Manager International Equity Strategies Fund (the "Fund"), a series of Columbia Funds Series Trust I (the "Trust"), in lieu of a proxy statement, pursuant to the terms of an exemptive order (the "Manager of Managers Order") that Columbia Management Investment Advisers, LLC (the "Investment Manager") received from the U.S. Securities and Exchange Commission (the "SEC"). The Manager of Managers Order permits the Investment Manager, subject to certain conditions such as approval by the Fund's Board of Trustees (the "Board"), and without approval by shareholders, to retain an unaffiliated subadviser (or subadvisers) to manage the Fund.

This Information Statement Is For Informational Purposes Only And No Action Is Requested On Your Part. We Are Not Asking You For A Proxy And You Are Requested Not To Send Us A Proxy.

THE FUND AND ITS MANAGEMENT AGREEMENT

The Investment Manager, located at 290 Congress Street, Boston, MA 02210, serves as investment manager to the Fund pursuant to a management agreement (the "Management Agreement"), amended and restated as of April 25, 2016, and most recently renewed at a meeting of the Board on June 27, 2024.

Under the Management Agreement, the Investment Manager, among other duties, monitors the performance of each subadviser on an ongoing basis. Factors it considers with respect to the selection and retention of a subadviser are, among others: the qualifications of the subadviser's investment personnel, its investment philosophy and process, its compliance program, and its long-term performance results. As compensation for its services, the Investment Manager receives a management fee from the Fund and, from this management fee, the Investment Manager pays each subadviser a subadvisory fee.

Subadvisers serve pursuant to separate subadvisory agreements with the Investment Manager under which a subadviser manages all or a portion of a fund's investment portfolio, as allocated to a subadviser by the Investment Manager, and provides related compliance and record-keeping services. In accordance with procedures adopted by the Board, affiliated broker-dealers of a subadviser may execute portfolio transactions for a subadvised fund and receive brokerage commissions in connection with those transactions as permitted by Rule 17e-1 under the Investment Company Act of 1940, as amended (the "1940 Act"), or separate SEC exemptive relief. A subadviser is allowed to use soft dollar arrangements in which it directs brokerage commissions to brokers to pay for research services it receives, provided that the subadviser's procedures are consistent with the Fund's and the Investment Manager's policies.

WALTER SCOTT & PARTNERS LIMITED AND THE SUBADVISORY AGREEMENT

At meetings of the Board and its committees on June 21 and 26-27, 2024 (the "June Meeting"), the Board, including a majority of the Board members who are not interested persons of the Fund within the meaning of the 1940 Act (the "Independent Trustees"), approved, in accordance with the recommendations of the Investment Manager, (i) a subadvisory agreement (the "Subadvisory Agreement") between the Investment Manager and Walter Scott & Partners Limited ("Walter Scott") with respect to the Fund; and (ii) modifications to the Fund's principal investment strategies to reflect Walter Scott's investment process for the portion of the Fund it manages.

The Subadvisory Agreement went into effect on August 13, 2024. Arrowstreet Capital, Limited Partnership ("Arrowstreet"), Baillie Gifford Overseas Limited ("Baillie Gifford"), and Causeway Capital Management LLC ("Causeway") continue to serve as subadvisers to the Fund, and there were no changes to the subadvisory agreements between the Investment Manager and Arrowstreet, Baillie Gifford and Causeway, respectively.

BOARD CONSIDERATION AND APPROVAL OF THE SUBADVISORY AGREEMENT

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 Multi-Manager International Equity Strategies Fund (the Fund). At its June 27, 2024, meeting (the June Meeting), the Board, including a majority of the Independent Trustees, unanimously approved the proposed subadvisory agreement between the Investment Manager and Walter Scott (the "Subadvisory Agreement") with respect to the Fund.

3

At the June Meeting, independent legal counsel to the Independent Trustees reviewed with the Board the legal standards for consideration by directors/trustees of advisory and subadvisory agreements and referred to the various written materials and oral presentations received by the Board and its Contracts, Compliance, and Investment Review Committees in connection with the Board's evaluation of Walter Scott's proposed services.

The Board held discussions with the Investment Manager and Walter Scott and reviewed and considered various written materials and oral presentations in connection with the evaluation of Walter Scott's proposed services, including the reports from management with respect to the fees and terms of the proposed Subadvisory Agreement and Walter Scott's investment strategy/style and performance and from the Compliance Committee, with respect to the code of ethics and compliance program of Walter Scott. Further, the Board observed that Walter Scott would utilize the same investment strategy that it uses in subadvising another Fund overseen by the Board (using the same portfolio management team). In considering the Subadvisory Agreement, the Board reviewed, among other things:

•

Terms of the Subadvisory Agreement;

•

Subadvisors fees payable by the Investment Manager under the Subadvisory Agreement;

•

Descriptions of various services proposed to be performed by Walter Scott under the Subadvisory Agreement, including portfolio management and portfolio trading practices;

•

Information regarding the experience and resources of Walter Scott, including information regarding senior management, portfolio managers, and other personnel;

•

Information regarding the capabilities of Walter Scott's compliance program; and

•

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

Following an analysis and discussion of the foregoing, and the factors identified below, the Board, including a majority of the Independent Trustees, upon the recommendation of the Investment Manager, unanimously approved the Subadvisory Agreement on June 27, 2024.

Nature, Extent and Quality of Services

The Board considered its analysis of the reports and presentations it received, detailing the services proposed to be performed by Walter Scott as a subadviser for the Fund, as well as the history,

4

reputation, expertise, resources and capabilities, and the qualifications of the personnel of Walter Scott. The Board considered the diligence and selection process undertaken by the Investment Manager to select Walter Scott, including the Investment Manager's rationale for recommending Walter Scott, and the process for monitoring Walter Scott's ongoing performance of services for the Fund. The Board noted that it is proposed that Walter Scott utilize the same investment strategy and portfolio management team that it uses in subadvising another Fund overseen by the Board, Variable Portfolio - Partners International Growth Fund. The Board observed that Walter Scott's compliance program had been reviewed by the Fund's Chief Compliance Officer and was determined by him to be reasonably designed to prevent violation of the federal securities laws by the Fund. The Board also observed that information had been presented regarding Walter Scott's ability to carry out its responsibilities under the proposed Subadvisory Agreement. The Board also considered the information provided by management regarding the personnel, risk controls, philosophy, and investment processes of Walter Scott. The Board also noted the presentation by Walter Scott to the Board's Investment Review Committee.

The Board also discussed the acceptability of the terms of the proposed Subadvisory Agreement. Independent Legal Counsel noted that the proposed Subadvisory Agreement was substantially identical to Walter Scott's existing subadvisory agreement for the Variable Portfolio - Partners International Growth Fund and generally similar in scope and form to subadvisory agreements applicable to other subadvised Funds. The Board noted the Investment Manager's representation that Walter Scott has experience subadvising registered mutual funds, including the other Fund overseen by the Board.

After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the expected nature, extent and quality of the services to be provided to the Fund supported the approval of the Subadvisory Agreement.

Investment Performance of Walter Scott

The Board observed Walter Scott's relevant performance results versus the Fund's benchmark and versus peers over various periods, noting outperformance versus the MSCI EAFE Growth Index for all

5

applicable periods. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the performance of Walter Scott, in light of other considerations, supported the approval of the Subadvisory Agreement.

Comparative Fees, Costs of Services Provided and Profitability

The Board reviewed the proposed level of subadvisory fees under the proposed Subadvisory Agreement, noting that the proposed subadvisory fees payable to Walter Scott would be paid by the Investment Manager and would not impact the fees paid by the Fund. The Board observed that the proposed subadvisory fees for Walter Scott were within a reasonable range of subadvisory fees paid by the Investment Manager to the subadvisers of other Funds with similar strategies. The Board observed that management fees, which were not proposed to change, remained within the range of other peers and that the Fund's expense ratio also remained within the range of other peers.

Additionally, the Board considered the expected decrease in the total profitability of the Investment Manager and its affiliates in connection with the hiring of Walter Scott. Because the Subadvisory Agreement was negotiated at arms-length by the Investment Manager, which is responsible for payments to the subadviser thereunder, the Board did not consider the profitability to Walter Scott from its relationship with the Fund.

After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the proposed level of subadvisory fees, anticipated costs of services provided and the expected profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the approval of the Subadvisory Agreement.

Economies of Scale

The Board also considered the economies of scale that may be realized by the Investment Manager and its affiliates as the Fund grows and took note of the extent to which shareholders might also benefit from such growth. The Board considered, in this regard, the expected decrease in profitability to the

6

Investment Manager from its management agreement with the Fund as a result of the proposed engagement of Walter Scott. The Board took into account, in this regard, the significant oversight services provided by the Investment Manager to the Fund. The Board also observed that fees to be paid under the Subadvisory Agreement would not impact fees paid by the Fund (as subadvisory fees are paid by the Investment Manager and not the Fund). The Board observed that the Fund's management agreement with the Investment Manager continues to provide for sharing of economies of scale as management fees decline as assets increase at pre-established breakpoints.

The Board also noted, for the Subadvisory Agreement, that there were no breakpoints proposed or the Subadviser's fees.

Conclusion

The Board reviewed all of the above considerations in reaching its decision to approve the Subadvisory Agreement. In reaching its conclusions, no single factor was determinative.

On June 27, 2024, the Board, including all of the Independent Trustees, determined that fees payable under the Subadvisory Agreement appeared fair and reasonable in light of the services proposed to be provided and approved the Subadvisory Agreement with respect to the Fund.

FUND ASSETS

For a mutual fund managed by subadvisers, such as the Fund, the Investment Manager, subject to the oversight of the Board, decides the proportion of Fund assets to be managed by the subadvisers, and may change these proportions at any time.

Prior to August 13, 2024, the long-term allocation target of the Fund's assets was as follows:

Arrowstreet		Baillie Gifford		Causeway
30%		35%		35%

As of August 13, 2024, the long-term allocation target of the Fund's assets was as follows:

Arrowstreet		Baillie Gifford		Causeway		Walter Scott
30%		17.5%		35%		17.5%
