PROXY STATEMENT FOR ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON APRIL 14, 2026

GENERAL

This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of Cornerstone Strategic Investment Fund, Inc., a Maryland corporation (the “Fund”) for use at the Annual Meeting of Stockholders for the year 2026 (the “Meeting”) to be held 11:30 a.m., Eastern Time, on April 14, 2026 at the First Floor Conference Room, 1075 Hendersonville Rd., Asheville, NC 28803, and at any and all adjournments and postponements thereof. A form of proxy is enclosed herewith. This Proxy Statement and the accompanying form of proxy are being first mailed to stockholders of the Fund (“Stockholder(s)”) on or about February 26, 2026.

Any Stockholder who executes and delivers a proxy may revoke it by written communication to the Secretary of the Fund at any time prior to its use or by voting in person at the Meeting. Attendance by a Stockholder at the Meeting does not, in itself, revoke a proxy. Unrevoked proxies will be voted in accordance with the specifications thereon and, unless specified to the contrary, will be voted FOR the election of Mr. Peter K. Greer and Ms. Marcia E. Malzahn as nominees for Class I Directors.

In general, abstentions and broker non-votes, as defined below, count for purposes of obtaining a quorum but do not count as votes cast with respect to any proposal requiring that the broker has discretion. With respect to a proposal requiring the affirmative vote of a majority of the Fund’s outstanding shares of common stock, the effect of abstentions and broker non-votes is the same as a vote against such proposal. Otherwise, abstentions and broker non-votes have no effect on the outcome of a proposal. A broker non-vote is a proxy from a broker or nominee indicating that such person has not received instructions from the beneficial owner or other person entitled to vote shares on a particular matter with respect to which the broker or nominee does not have discretionary voting power.

At least one-third of the Fund’s Stockholders must be present at the Meeting in person or by proxy to constitute a quorum for the transaction of business by the Fund. In the event that a quorum is not present at the Meeting, the persons named as proxies may propose one or more adjournments of the Meeting from time to time. Any such adjournment will require the affirmative vote of a majority of those shares represented at the Meeting in person or by proxy. The persons named as proxies will vote those proxies which they are entitled to vote FOR or AGAINST any such proposal in their discretion.

Your vote is being solicited by the directors of the Fund. The cost of soliciting these proxies will be borne by the Fund. The Fund will reimburse brokerage firms and others for their expenses in forwarding proxy materials to the beneficial owners and soliciting them to execute proxies.

The directors and officers of the Fund, Equiniti Trust Company, LLC, the stock transfer agent to the Fund (“Equiniti”), and Ultimus Fund Solutions, LLC, the administrator to the Fund (the “Administrator”), may be involved in the solicitation of proxies. The Fund does not reimburse such persons for the solicitation of proxies.

The Fund expects that the solicitation will be primarily by mail, but also may include telephone, electronic, oral or other means of communication. If the Fund does not receive your proxy by a certain time, you may receive a telephone call from a proxy soliciting agent asking you to vote. The cost of soliciting the proxies will be borne by the Fund.

Only holders of issued and outstanding shares of the Fund’s common stock of record at the close of business on February 13, 2026 are entitled to notice of, and to vote at, the Meeting. Each such holder is entitled to one vote per share of common stock so held. The number of shares of common stock outstanding on February 13, 2026 was 297,921,983. The Fund is a diversified, closed-end management investment company.

Copies of the Fund’s most recent annual and semi-annual report may be ordered free of charge to any Stockholder by writing to the Fund, c/o Ultimus Fund Solutions, LLC, 225 Pictoria Drive, Suite 450, Cincinnati, OH 45246, or by calling (866) 668-6558. This report is not to be regarded as proxy-soliciting material.

This Proxy Statement is first being mailed to Stockholders on or about February 26, 2026.

PROPOSAL NO. 1
ELECTION OF DIRECTORS

In accordance with the Fund’s By-laws, the Fund’s Board of Directors is divided into three classes: Class I, Class II and Class III. Each class has a term of three years and each year the term of office of one class expires. The effect of these staggered terms is to limit the ability of other entities or persons to acquire control of the Fund by delaying the replacement of a majority of the Board of Directors.

At the Meeting, Stockholders will be asked to elect Mr. Peter K. Greer and Ms. Marcia E. Malzahn as Class I directors to hold office until the year 2029 Annual Meeting of Stockholders or thereafter until each of their respective successors is duly elected and qualified. If elected, the term of office of the Class I Directors will expire at the year 2029 Annual Meeting or thereafter until his or her respective successor is duly elected and qualified. If elected, each nominee has consented to serve as a Director of the Fund until his or her successor is duly elected and qualified. Each nominee was considered and recommended by the Fund’s Nominating and Corporate Governance Committee. Each of Robert E. Dean, a current non-interested director, and Daniel W. Bradshaw, a current interested director, will step down from the Board of Directors as of the Annual Meeting date and is not standing for re-election.

Under the terms of the Board’s retirement policy, unless the Board has granted an exception, a non-interested director shall retire as of the date of the annual meeting, typically in April, following the calendar year such non-interested director attains the age of 76 years.

The persons named in the accompanying form of proxy intend to vote at the Meeting (unless directed not to vote) FOR the election of each nominee. Each nominee has indicated that he or she will serve if elected, and the Board of Directors has no reason to believe that any of the nominees named above will become unavailable for election as a director, but if any nominee should be unable to serve, the proxy will be voted for any other person determined by the persons named in the proxy in accordance with their judgment.

***	Mr. Ralph Bradshaw is the father of Mr. Joshua Bradshaw.

The Board believes that the significance of each Director’s experience, qualifications, attributes or skills is an individual matter (meaning that experience that is important for one Director may not have the same value for another) and that these factors are best evaluated at the Board level, with no single Director, or particular factor, being indicative of the Board’s effectiveness. The Board determined that each of the Directors is qualified to serve as a Director of the Fund based on a review of the experience, qualifications, attributes and skills of each Director. In reaching this determination, the Board has considered a variety of criteria, including, among other things: character and integrity; ability to review critically, evaluate, question and discuss information provided, to exercise effective business judgment in protecting stockholder interests and to interact effectively with the other Directors, the Investment Adviser, other service providers, counsel and the independent registered accounting firm (“independent auditors”); and willingness and ability to commit the time necessary to perform the duties of a Director. Each Director’s ability to perform his duties effectively is evidenced by his experience or achievements in the following areas: management or board experience in the investment management industry or companies or organizations in other fields, educational background and professional training; and experience as a Director of the Fund. In addition, the Board values the diverse skill sets and experiences that each Director contributes. The Board considers that its diversity as a whole is as a result of a combination of Directors who are working in the private, as opposed to public, sector, those that are retired from professional work and the various perspectives that each Director provides as a result of his present experiences and his background. Information as of December 31, 2025 discussing the specific experience, skills, attributes and qualifications of each Director which led to the Board’s determination that the Director should serve in this capacity is provided below.

Bradshaw, who is not standing for re-election and will cease to be a Director as of the Annual Meeting date, is currently an Interested Director and is an Assistant Secretary of the Fund, and is an Assistant Secretary and a director of Cornerstone Total Return Fund, Inc. The Board does not have a lead independent director.

The Board believes that its structure facilitates the orderly and efficient flow of information to the Directors from the Investment Adviser and other service providers with respect to services provided to the Fund, potential conflicts of interest that could arise from these relationships and other risks that the Fund may face. The Board further believes that its structure allows all of the Directors to participate in the full range of the Board’s oversight responsibilities. The Board believes that the orderly and efficient flow of information and the ability to bring each Director’s talents to bear in overseeing the Fund’s operations is important, in light of the size and complexity of the Fund and the risks that the Fund faces. The Board and its committees review their structure regularly, to help ensure that it remains appropriate as the business and operations of the Fund and the environment in which the Fund operates changes.

Currently, the Board has an Audit Committee and a Nominating and Corporate Governance Committee. The responsibilities of each committee and its members are described below. The Board convened five (5) times during the 2025 calendar year (including regularly scheduled and special meetings). Each of the Directors attended at least seventy-five (75%) percent of the meetings held during the period for which he or she was a member. Each director attended at least seventy-five percent (75%) of the four (4) meetings of its Audit Committee (including regularly scheduled and special meetings) held during the period for which he or she was a member. Each director attended at least seventy-five (75%) percent of the four (4) meetings of its Nominating and Corporate Governance Committee (including regularly scheduled and special meetings) held during the period for which he or she was a member. The Board does not have a policy regarding Directors’ attendance at the Annual Stockholders Meeting, but all are invited to attend.

THE AUDIT COMMITTEE

The Fund has a standing Audit Committee (the “Audit Committee”), which is comprised of Messrs. Dean, Greer, Maresca, Morris, Rogers and Strauss, and Ms. Malzahn, all of whom are Directors who are not interested persons of the Fund, as such term is defined in Section 2(a)(19) of the Investment Company Act of 1940, as amended. The Audit Committee has a written charter. The principal functions of the Audit Committee include but are not limited to, (i) the oversight of the accounting and financial reporting processes of the Fund and its internal control over financial reporting; (ii) the oversight of the quality and integrity of the Fund’s financial statements and the independent audit thereof; and (iii) the approval, prior to the engagement of, the Fund’s independent registered public accounting firm and, in connection therewith, to review and evaluate the qualifications, independence and performance of the Fund’s independent registered public accounting firm. The Audit Committee convened four (4) times during the 2025 calendar year.

The Board has appointed Mr. Maresca to be the Audit Committee Financial Expert, as such term is defined in Section 407 of the Sarbanes-Oxley Act of 2002.

The responsibilities of the Audit Committee, as approved by the Directors, are set forth in the Audit Committee Charter, a copy of which is available on the Fund’s website at www.cornerstonestrategicInvestmentfund.com under the section “Corporate Governance – Audit Committee Charter.”

THE NOMINATING AND CORPORATE GOVERNANCE COMMITTEE

The Fund has a standing Nominating and Corporate Governance Committee (the “N&CG Committee”), which is comprised of Messrs. Dean, Greer, Maresca, Morris, Rogers and Strauss, and Ms. Malzahn, all of whom are Directors who are not interested persons of the Fund, as such term is defined in Section 2(a)(19) of the Investment Company Act of 1940, as amended. The N&CG Committee has a written charter. In addition to its responsibility to oversee the corporate governance of the Fund, the N&CG

Committee is appointed to identify and select qualified candidates that have exhibited strong decision making ability, substantial business experience, relevant knowledge of the investment company industry (including closed-end funds), skills or technological expertise and exemplary personal integrity and reputation. In addition, the N&CG Committee seeks candidates that have experience and knowledge of the service providers of a registered investment company.

The N&CG Committee will consider all nominees recommended by Stockholders of the Fund, so long as Stockholders send their recommendations in writing to the Secretary of the Fund in a manner consistent with the Fund’s By-laws. The N&CG Committee will seek candidates for the Board that have exhibited strong decision-making ability, substantial business experience, relevant knowledge, skills or technological expertise, and exemplary personal integrity and reputation. Specifically, the N&CG Committee assesses all director nominees taking into account several factors, including, but not limited to, issues such as the current needs of the Board and the nominee’s: (i) integrity, honesty, and accountability; (ii) successful leadership experience and strong business acumen; (iii) forward-looking, strategic focus; (iv) collegiality; (v) independence and absence of conflicts of interests; and (vi) ability to devote necessary time to meet director responsibilities. The N&CG Committee does not have a policy with regard to considering diversity when identifying candidates for election, but would expect to consider race, gender and professional experience diversity when identifying future candidates. The N&CG Committee will ultimately recommend nominees that it believes will enhance the Board’s ability to oversee, in an effective manner, the affairs and business of the Fund. The N&CG Committee will consider and evaluate Stockholder-recommended candidates by applying the same criteria used to evaluate director-recommended candidates. The deadline for submitting a Stockholder proposal for inclusion in the Fund’s proxy statement and proxy for the Fund’s 2027 annual meeting of stockholders pursuant to Rule 14a-8 promulgated under the Securities Exchange Act of 1934, is October 29, 2026. Stockholders wishing to submit proposals or director nominations that are to be included in such proxy statement and proxy must deliver notice to the Secretary at the principal executive offices of the Fund no later than the close of business on October 29, 2026. Stockholders are also advised to review the Fund’s By-laws, which contain additional requirements with respect to advance notice of stockholder proposals and director nominations.

In February 2026, the N&CG Committee met and discussed the nomination of the Class I Director nominees of the Fund for the 2026 Annual Meeting of Stockholders. The Nominees were recommended by the N&CG Committee, comprised of the non-interested Directors. The N&CG Committee convened four (4) times during the 2025 calendar year.

The responsibilities of the N&CG Committee, as approved by the Directors, are set forth in the N&CG Committee Charter, a copy of which is available on the Fund’s website at www.cornerstonestrategicInvestmentfund.com under the section “Corporate Governance – Nominating and Corporate Governance Committee Charter.”

BOARD’S ROLE IN RISK OVERSIGHT OF THE FUND

The Board oversees risk management for the Fund directly and, as to certain matters, through its Audit and Nominating and Corporate Governance Committees. The Board exercises its oversight in this regard primarily through requesting and receiving reports from and otherwise working with the Fund’s senior officers (including the Fund’s Chief Compliance Officer), portfolio management personnel of the Investment Adviser, the Fund’s independent auditors, legal counsel and personnel from the Fund’s other service providers. The Board has adopted, on behalf of the Fund, and periodically reviews with the assistance of Fund personnel, policies and procedures designed to address certain risks associated with the Fund’s activities. In addition, the Investment Adviser and the Fund’s other service providers have also adopted policies, processes and procedures designed to identify, assess and manage certain risks associated with the Fund’s activities, and the Board receives reports from service providers with respect to the operation of these policies, processes and procedures as required and/or as the Board deems appropriate. The Board does not believe that a separate Risk Oversight Committee is necessary for effective risk oversight at this time, but intends to continuously evaluate how it assesses risk and consider whether any changes to the current structure are prudent.

REQUIRED VOTE

Directors are elected by a plurality of the votes cast by the holders of shares of common stock of the Fund present in person or represented by proxy at a meeting with a quorum present. For purposes of the election of Directors, abstentions and broker non-votes will be counted as shares present for quorum purposes, may be considered votes cast, and may affect the plurality vote required for Directors. Proposal No. 1 is considered a “routine” matter under the rules of the New York Stock Exchange (“NYSE”), and beneficial owners who do not provide proxy instructions or who do not return a proxy card may have their shares voted by broker-dealer firms on the proposal in the discretion of such broker-dealer firms.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE ELECTION OF MR. PETER K. GREER AND MS. MARCIA E. MALZAHN AS CLASS I DIRECTORS OF THE FUND.

AUDIT COMMITTEE REPORT

In February 2026, the Audit Committee met with the Fund’s Administrator, Ultimus Fund Solutions, LLC, and the Fund’s independent registered public accounting firm, Cohen & Company, Ltd., to discuss and review the Fund’s audited financial statements for the calendar year ended December 31, 2025. The Fund’s independent registered public accounting firm represented to the Audit Committee that the Fund’s financial statements were prepared in accordance with U.S. Generally Accepted Accounting Principles, and the Audit Committee has reviewed and discussed the financial statements with the Fund’s Administrator and its independent registered public accounting firm. The Audit Committee also discussed with the independent registered public accounting firm matters required to be discussed by current auditing standards.

The Fund’s independent registered public accounting firm also provided to the Audit Committee the written disclosures required by current independence standards regarding Independence Discussions with Audit Committees, and the Audit Committee discussed with the independent registered public accounting firm their independence, in light of the services they were providing.

Based upon the Audit Committee’s discussion with the Fund’s Administrator and the independent registered public accounting firm and the Audit Committee’s review of the representations and report of the independent registered public accounting firm to the Audit Committee, the Audit Committee recommended that the Board of Directors include the audited financial statements in the Fund’s Annual Report for the calendar year ended December 31, 2025 filed with the Securities and Exchange Commission (the “SEC”).

This Audit Committee report shall not be deemed incorporated by reference in any document previously or subsequently filed with the SEC that incorporates by reference all or any portion of this proxy statement except to the extent that the Fund specifically requests that the report be specifically incorporated by reference.

	Frank J. Maresca, Chairman
