As set forth in the Company’s bylaws, except as otherwise provided in the Company’s charter and notwithstanding any other provision of Maryland law, unless all nominees for director are approved by a majority of the Continuing Directors (as such term is defined in the Company’s governing documents), the affirmative vote of the holders of at least two-thirds of the outstanding shares of all classes of voting stock, voting together, shall be required to elect a director. However, if all nominees for director are approved by a majority of the Continuing Directors, a plurality of all the votes cast at a meeting at which a quorum is present shall be sufficient to elect a director. Inasmuch as the election of each of the Nominees was approved by a majority of the Continuing Directors, a plurality of all the votes cast at the Meeting at which a quorum is present shall be sufficient to elect each of the Nominees. Because directors will be elected by a plurality of the votes cast in the election of directors, and no additional nominations may properly be presented at the Meeting, “withhold” votes will have no effect on the result of the vote on this proposal. Abstentions and broker non-votes are not votes cast and will have no effect on the result of the vote on this proposal, although they will be considered present for the purpose of determining the presence of a quorum. Proxies solicited by the Board will be voted "FOR" each of the Nominees, unless otherwise instructed.

The purpose of the Audit Committee is to meet with the Company’s independent registered public accounting firm (“independent registered public accounting firm”) to review its financial reporting, external audit matters, and fees charged by the Company’s independent registered public accounting firm and to evaluate the independence of the independent registered public accounting firm.

Currently, the Independent Directors are paid an annual retainer of $2,000, payable semi-annually, a fee of $10,500 for each semi-annual regular Board meeting attended, $250 for each special Board meeting attended, $250 for each committee meeting attended, $500 per annum per committee chaired, and $500 for attendance at the Company’s annual meeting of stockholders. Each Independent Director is reimbursed for reasonable travel and out-of-pocket expenses associated with attending Board and committee meetings.

Retainer payments are prorated when a director joins the Board other than at the beginning of a calendar year.

Each Independent Director may elect to receive, at any time, the value of their cash compensation in shares of common stock of the Company reserved under the 2017 Equity Incentive Plan (the "Plan").

A summary of the compensation and benefits for the Independent Directors for the fiscal year ended December 31, 2023 is shown in the following table:

(1) Each of Messrs. Burke and Zachary elected to receive payment of a portion of the value of his cash compensation in shares of common stock. Accordingly, Burke and Zachary were each awarded 2,294 shares of common stock from the Plan. The shares were unrestricted and vested immediately. The dollar values shown in the table for the share awards represent the aggregate grant date fair value computed in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718.

Each director’s background and his oversight and service as a member of other boards of directors was evaluated in determining whether he/she should serve as a director of the Company. With respect to the specific experience, qualifications, attributes, or skills that led to the conclusion that each person should serve as a director of the Company, each director’s relevant knowledge, experience, expertise, and independence was considered and evaluated. Burke was selected to serve on the Board because of his prior experience serving on the board of another self storage company and his experience and extensive knowledge of the self storage industry. Langa was selected to serve on the Board because of his experience with and extensive knowledge of commercial real estate transactions, marketing, and management. Zachary was selected to serve on the Board because of his prior experience serving on the board of another self storage company and his experience in underwriting finance.

Thomas Winmill, Esq. was selected to serve on the Board because of his experience with finance, accounting, regulatory, investment, and board operational matters as a result of his service as an officer and director for more than 20 years of the Funds. Mark Winmill was selected to serve on the Board because of his experience and extensive knowledge of the self storage industry and matters relating to real estate development, finance, accounting, and board operations. Each of the directors has experience with finance, accounting, regulatory, and board operational matters as a result of his/her service as a director on the Board and other boards of directors.

We are focused on building our company for the long-term to generate sustainable growth. To that end, we have established a cross-functional Environmental, Social, and Governance (“ESG”) committee, comprised of management, responsible for establishing our sustainability priorities and objectives. Management regularly evaluates sustainability risks faced by our portfolio and believes the low obsolescence, geographic diversification, and low emissions of our portfolio help to mitigate those risks. Our ESG committee reports annually to the Board on the status of our ESG program, our progress against the goals we have set, and provide updates on the various initiatives we have undertaken to improve our sustainability.

A key area of focus from a sustainability perspective is minimizing the impact we make on the environment. Self-storage remains a low-environmental impact business as it consumes less energy and water while emitting fewer greenhouse gases than other real estate property types. We continue to look for ways to further reduce our low impact through a variety of initiatives including solar panel installations, HVAC upgrades, high-efficiency LED lighting retrofits, energy management systems, and paper reduction through our online rental platform. We continue to explore the installation of solar panels at our properties which we expect would reduce energy consumption and costs at such locations.

We are committed to managing climate-related risks and opportunities in relation to our business. This commitment is a key component of our recognition that we must operate in a responsible and sustainable manner that aligns with our long-term corporate strategy and promotes our best interests along with those of our stakeholders, including our tenants, investors, employees, and the communities in which we operate.

Our ESG committee guides our commitment to sustainability and will have primary responsibility for climate-related activities. Our ESG committee reports annually to the Board, which oversees all of our sustainability initiatives.

We consider potential environmental impacts—both positive and negative—in our decision making across the business. The following features of our properties reflect our commitment to responsible environmental stewardship:

We seek to create a diverse and inclusive work environment that values each employee’s talents and contributions. Our success relies on the general professionalism of our property managers and staff which are contributing factors to our ability to successfully secure rentals, retain tenants and maintain clean and secure self storage properties. We seek to increase employee retention and well-being and our employees enjoy an attractive benefit package that includes medical, dental, vision, life insurance, 401(k) with matching employer contribution, cash bonuses, and long-term equity compensation. We offer competitive health benefits and encourage our employees to participate in employee health and wellness programs. We also offer individualized counseling to our employees to assist them with their journey towards better health.

We also seek to promote diversity among our employees and management team. As of December 31, 2023, approximately 40% of our non-store (including finance, human resources, accounting, tax, legal, and marketing, but excluding store-level

operations) employees were women. As of December 31, 2023, we had 35 employees, which includes employees of our property management platform.

In order to attract and retain diverse top talent, we offer training and development opportunities for our employees. In 2023, we offered training and development for our employees, which included anti-harassment training, cyber security training, and site manager training. We value the safety of our employees and provide regular training for our employees to increase safety at our properties. During 2024, we continued to make masks and other personal protective equipment available to our employees.

We remain committed to strong governance practices and the highest ethical standards. For further details on our corporate governance, see the section of this proxy statement titled “Corporate Governance.”

We have adopted a Code of Conduct and Ethics in compliance with rules of the SEC that applies to all of our personnel, including the Board, Chief Executive Officer and Chief Financial Officer. The Code of Conduct and Ethics is available free of charge on the “Governance Documents” section of our website at www.GlobalSelfStorage.us. We intend to satisfy any disclosure requirements under Item 5.05 of Form 8-K regarding amendments to, or waivers from, provisions of our Code of Conduct and Ethics by posting such information on our web site at the address specified above.

The Nasdaq Listing Rules generally require that a majority of the members of a listed company’s board of directors be independent. In addition, the listing rules generally require that, subject to specified exceptions, each member of a listed company’s audit, compensation and governance committees be independent.

Accordingly, the Board has evaluated the independence of its members based upon the rules of Nasdaq and the SEC and the transactions referenced under “Certain Relationships and Related Party Transactions” in this Proxy Statement. Applying these standards, the Board determined that none of the directors who currently serve, other than Mark and Thomas Winmill, have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that Burke, Langa, Zachary, and Carroll are “independent” as that term is defined under Rule 5605(a)(2) of the Nasdaq Listing Rules. Mark and Thomas Winmill are not considered independent because they are officers of the Company and/or its affiliates. The Board also determined that each non-employee director who serves as a member of the Audit, Compensation and Nominating & Governance Committees satisfies the independence standards for such committee established by the SEC and the Nasdaq Listing Rules, as applicable.

The Board is responsible for the oversight of the Company’s operations. The Board is currently composed of six members, four of whom are Independent Directors. As described above, the Board has established five standing committees, the Audit Committee, Compensation Committee, Nominating & Governance Committee, Executive Committee and Committee of Continuing Directors, and may establish ad hoc committees or working groups from time to time, to assist the Board in fulfilling its oversight responsibilities. The inclusion of all Independent Directors as members of the Audit, Compensation, Nominating & Governance, and Continuing Directors committees allows all the Independent Directors to participate in the full range of the Board’s oversight duties, including oversight of risk management processes discussed below.

The Board has designated Mark Winmill to serve as the Chairman of the Board (the “Chairman”). M. Winmill has been active in the real estate and self storage industries for over 20 years as chief executive officer and in other capacities. The Chairman presides at each Board meeting, establishes the agenda for Board meetings, and acts as the primary liaison between the Independent Directors and Company management. The Chairman of the Board is an “interested person” of the Company. The Independent Directors have not appointed a lead Independent Director. The Independent Directors believe that the utilization of an interested person as Chairman provides an efficient structure for them to coordinate with Company management in carrying out their responsibilities. The Chairman plays an important role in communicating with them in identifying matters of special interest to be addressed by Company management and the Board. The Chairman may also perform such other functions as may be requested by the directors from time to time. Designation as Chairman does not impose on such director any duties or standards

greater than or different from other directors. The directors believe that the Board’s leadership structure, taking into account, among other things, its committee structure, which permits certain areas of responsibility to be allocated to the Independent Directors, is appropriate given the characteristics and circumstances of the Company.

The operation of the Company generally involves a variety of risks. As part of its oversight of the Company, the Board oversees risk management through various regular Board and committee activities. The Board, directly or through its committees, reviews reports from, among others, the Company’s management, including the Company’s Chief Compliance Officer, the Company’s independent registered public accounting firm, outside legal counsel, and others, as appropriate, regarding risks faced by the Company and the extent of its risk management programs. Although the Company’s risk management program is designed to be effective, there is no guarantee that it will anticipate or mitigate all risks. Not all risks that may affect the Company can be identified, eliminated, or mitigated and some risks may not be anticipated or may be beyond the control of the Board or the Company.

Information Regarding the Company’s Process for Director Candidate Recommendations and Director Selection Criteria

In identifying potential nominees for the Board, the Nominating & Governance Committee may consider candidates recommended by one or more of the following sources: (i) the Company’s current directors, (ii) the Company’s officers, (iii) the Company’s affiliates, (iv) the Company’s stockholders, and (v) any other source the Nominating & Governance Committee deems to be appropriate. The Nominating & Governance Committee will not consider self-nominated candidates. The Nominating & Governance Committee may, but is not required to, retain a third-party search firm at the Company’s expense to identify potential candidates. The Nominating & Governance Committee may consider, among other things, diversity of gender, race, national origin, ethnicity, culture, age, religion, military service, socio-economic background, and experience and skills as factors in choosing director candidates, but has not adopted any specific policy in this regard.

Pursuant to the Company’s governing documents, to qualify as a nominee for a directorship, an individual, at the time of nomination, (i)(A) shall be a resident United States citizen and have substantial expertise, experience or relationships relevant to the business of the Company, and (B) shall have a master’s degree in economics, finance, business administration or accounting, a graduate professional degree in law from an accredited university or college in the United States or the equivalent degree from an equivalent institution of higher learning in another country, or a certification as a public accountant in the United States, or be deemed an “audit committee financial expert” as such term is defined in Item 401 of Regulation S-K (or any successor provision) of the Exchange Act; or (ii) shall be a current director of the Company. In addition, to qualify as a nominee for a directorship or election as a director, (i) an incumbent nominee shall not have violated any provision of the Conflicts of Interest and Corporate Opportunities Policy (the “Policy”), adopted by the Board on July 8, 2003, as subsequently amended or modified, and (ii) an individual who is not an incumbent director shall not have a relationship, hold any position or office or otherwise engage in, or have engaged in, any activity that would result in a violation of the Policy if the individual were elected as a director. The Nominating & Governance Committee, in its sole discretion, shall determine whether an individual satisfies the foregoing qualifications. Any individual who does not satisfy the qualifications set forth under the foregoing provisions of this section shall not be eligible for nomination or election as a director. In addition, no person shall be qualified to be a director unless the Nominating & Governance Committee, in consultation with counsel to the Company, has determined that such person, if elected as a director, would not cause the Company to be in violation of, or not in compliance with, applicable law, regulation or regulatory interpretation, or the Company’s charter, or any general policy adopted by the Board regarding either retirement age or the percentage of interested persons and non-interested persons to comprise the Company’s Board.

The Nominating & Governance Committee will consider and evaluate nominee candidates properly submitted by stockholders on the basis of the same criteria used to consider and evaluate candidates recommended by other sources. Nominee candidates proposed by stockholders will be properly submitted for consideration by the Nominating & Governance Committee only if the qualifications and procedures set forth in the Nominating & Governance Committee charter, as it may be amended from time to time by the Nominating & Governance Committee or the Board, are met and followed (recommendations not properly submitted will not be considered by the Nominating & Governance Committee).

A candidate recommended for nomination as a director submitted by a stockholder will not be deemed to be properly submitted to the Nominating & Governance Committee for the Nominating & Governance Committee’s consideration unless the following qualifications have been met and procedures followed:

1. A stockholder or group of stockholders (referred to in either case as a “Nominating Stockholder”) that, individually or as a group, has beneficially owned at least 5% of the Company’s common stock for at least two years prior to the date the Nominating Stockholder submits a candidate for nomination as a director may submit one candidate to the Nominating & Governance Committee for consideration at an annual meeting of stockholders.

2. The Nominating Stockholder must submit any such recommendation (a “Stockholder Recommendation”) in writing to the Company, to the attention of the Secretary, at the address of the principal executive offices of the Company.

3. The Stockholder Recommendation must be delivered to or mailed and received at the principal executive offices of the Company not less than 120 calendar days before the first anniversary date of the Company’s proxy statement released to stockholders in connection with the previous year’s annual meeting of stockholders.

4. The Stockholder Recommendation must include: (i) a statement in writing setting forth (A) the name, date of birth, business address and residence address of the person recommended by the Nominating Stockholder (the “Candidate”); (B) any position or business relationship of the candidate, currently or within the preceding five years, with the Nominating Stockholder or an Associated Person of the Nominating Stockholder (as defined below); (C) the class or series and number of all shares of stock of the Company owned of record or beneficially by the Candidate, as reported to such Nominating Stockholder by the Candidate; (D) any other information regarding the Candidate that is required to be disclosed about a nominee in a proxy statement or other filing required to be made in connection with the solicitation of proxies for election of directors pursuant to the Exchange Act; (E) whether the Nominating Stockholder believes that the Candidate is or will be an Independent Director and, if believed not to be an “independent director,” information regarding the Candidate that will be sufficient for the Company to make such determination; and (F) information as to the Candidate’s knowledge of the Company’s industry, experience as a director or senior officer of public companies, and educational background; (ii) the written and signed consent of the Candidate to be named as a nominee and to serve as a director if elected; (iii) the written and signed agreement of the Candidate to complete a directors’ and officers’ questionnaire if elected; (iv) the Nominating Stockholder’s consent to be named as such by the Company; (v) the class or series and number of all shares of stock of the Company owned beneficially and of record by the Nominating Stockholder and any Associated Person of the Nominating Stockholder and the dates on which such shares were acquired, specifying the number of shares of stock owned beneficially but not of record by each, and stating the names of each as they appear on the Company’s record books and the names of any nominee holders for each; and (vi) a description of all arrangements or understandings between the Nominating Stockholder, the Candidate and/or any other person or persons (including their names) pursuant to which the recommendation is being made by the Nominating Stockholder. “Associated Person of the Nominating Stockholder” as used herein means any person required to be identified pursuant to clause (vi) and any other person controlling, controlled by or under common control with, directly or indirectly, (a) the Nominating Stockholder or (b) any person required to be identified pursuant to clause (vi).

5. The Nominating & Governance Committee may require the Nominating Stockholder to furnish such other information as it may reasonably require or deem necessary to verify any information furnished pursuant to the requirements of the Nominating & Governance Committee charter or to determine the qualifications and eligibility of the Candidate proposed by the Nominating Stockholder to serve on the Board. If the Nominating Stockholder fails to provide such other information in writing within seven days of receipt of written request from the Nominating & Governance Committee, the recommendation of such Candidate as a nominee will be deemed not properly submitted for consideration, and will not be considered, by the Nominating & Governance Committee.

A detailed description of the criteria used by the Nominating & Governance Committee as well as information required to be provided by stockholders submitting candidates for consideration by the Nominating & Governance Committee are included in the Nominating & Governance Committee charter. The Nominating & Governance Committee charter, as amended, was approved by the Board on March 25, 2024.

The Board has determined that it has three “audit committee financial experts” (as that term is defined under SEC rules implementing Section 407 of the Sarbanes-Oxley Act) serving on the Audit Committee, each of whom are “independent” directors that satisfy the heightened audit committee independence requirements under the Nasdaq Listing Rules and Rule 10A-3 of the Exchange Act. Further, each member of the Audit Committee possesses the requisite financial sophistication, as required by the Nasdaq Listing Rules.

The Independent Directors serving on the Board regularly meet in executive session with outside counsel at board meetings.

The Company does not have a formal policy regarding attendance by directors at annual meetings of stockholders but encourages such attendance. The Company held an annual meeting of stockholders for the fiscal year ended December 31, 2023 on June 6, 2023, at which all directors were in attendance.

The Audit Committee has established procedures for (i) the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters, and (ii) the confidential and anonymous submission by the Company’s employees of concerns regarding questionable accounting or auditing matters. If you wish to contact the Audit Committee to report complaints or concerns relating to the financial reporting of the Company, you may do so by delivering the report via regular mail, which may be mailed anonymously, to the Audit Committee Chair, c/o Global Self Storage Inc., 3814 Route 44, Millbrook, New York 12545.

PROPOSAL 2: TO ratify the appointment of RSM US LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024.

The Audit Committee is empowered to appoint a firm to serve as the Company’s independent registered public accounting firm. The Audit Committee has previously appointed RSM to serve as the Company’s independent registered public accounting firm for the fiscal period commencing January 1, 2024. RSM served as the Company’s independent registered public accounting firm for the year ended December 31, 2023.

Although the Audit Committee has sole authority to appoint, re-appoint, and dismiss the Company’s independent registered public accounting firm, it is seeking the opinion of the stockholders regarding its appointment of RSM as the Company’s independent registered public accounting firm. For this reason, stockholders are being asked to ratify this appointment. If stockholders ratify the appointment of RSM as the Company’s independent registered public accounting firm, the Audit Committee will take that fact into consideration, but may, nevertheless, dismiss RSM. If stockholders do not ratify the appointment of RSM as the Company’s independent registered public accounting firm, the Audit Committee will take that fact into consideration, but may, nevertheless, continue to retain RSM.

Representatives of RSM are expected to be present at the Annual Meeting and will be provided with an opportunity to make a statement if so desired and to respond to appropriate inquiries.

The following table presents the aggregate fees for professional audit services rendered for the integrated audits of our annual financial statements for the years ended December 31, 2023 and 2022, for the reviews of the financial statements included in our Quarterly Reports on Form 10-Q for those fiscal years and fees billed for other services rendered during those periods.

(1) Audit fees consist of services rendered for the audit of our annual financial statements and other financial disclosures, review of the consolidated financial statements included in our Form 10-Q filings.

(2) Audit-related fees represent professional fees for accounting consultation and consents issued related to registration statements, and comfort letters.

(3) Tax fees represent professional services rendered for tax compliance, tax advice and tax planning.

Audit Committee Pre-Approval of Services by the Independent Registered Public Accounting Firm

In accordance with the Audit Committee charter, which sets forth the Audit Committee’s responsibilities, and applicable rules and regulations adopted by the SEC, the Audit Committee reviews and pre-approves any engagement of the independent registered public accounting firm to provide audit, review or attest services or non-audit services and the fees for any such services. The Audit Committee annually considers and, if appropriate, approves the provision of audit services by the independent registered public accounting firm. In addition, the Audit Committee periodically considers and, if appropriate, approves the provision of any additional audit and non-audit services by our independent registered public accounting firm that are neither pre-approved by the Audit Committee on an annual basis nor prohibited by applicable rules and regulations of the SEC. The Audit Committee has delegated to the chairman of the Audit Committee, Zachary, the authority to pre-approve, on a case-by-case basis, any such additional audit and non-audit services to be performed by our independent registered public accounting firm. Zachary reports any decision to pre-approve such services to the Audit Committee at its next regular meeting. All of the fees described in the table above were pre-approved by the Audit Committee.

The Audit Committee has reviewed and discussed the Company’s audited financial statements in the Company’s annual report on Form 10-K for the year ended December 31, 2023 with Company management and RSM. The Audit Committee has also discussed with RSM the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC.

The Audit Committee has received the written disclosures and the letter from RSM pursuant to the applicable requirements of the PCAOB regarding RSM’s communications with the Audit Committee concerning independence and the Audit Committee has discussed with RSM its independence with respect to the Company.

Based on the foregoing review and discussions, the Audit Committee recommended to the Board (and the Board approved) that the Company’s audited financial statements be included in the Company’s annual report on Form 10-K for the year ended December 31, 2023 filed with the SEC.

The foregoing Audit Committee Report shall not be deemed under the Securities Act of 1933, as amended, or the Exchange Act, to be (i) “soliciting material” or “filed” or (ii) incorporated by reference by any general statement into any filing made by us with the SEC, except to the extent that we specifically incorporate such report by reference.

Under Section 6 of Article II of the Company’s bylaws, a majority of the votes cast at a meeting of stockholders duly called and at which a quorum is present is sufficient to approve any matter which may properly come before the Meeting, unless more than a majority of the votes cast is required by statute or the Company’s charter. Inasmuch as Proposal 2 does not require a greater vote by statute or the Company’s charter, a majority of all the votes cast at the Meeting at which a quorum is present is sufficient to ratify the appointment of the independent registered public accounting firm. Abstentions are not votes cast and will have no effect on the result of the vote on this proposal, although they will be considered present for the purpose of determining the presence of a quorum. Proxies solicited by the Board will be voted "FOR" this proposal, unless otherwise instructed.

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE PROPOSAL TO RATIFY THE APPOINTMENT OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

PROPOSAL 3: to approve, ON A NON-BINDING, ADVISORY BASIS, the Company’s executive compensation.

As required by Section 14A of the Exchange Act, and in accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, stockholders are being asked to approve, on a non-binding, advisory basis, the Company’s executive

compensation. This “say-on-pay” vote is a non-binding, advisory vote on whether to approve the Company’s executive compensation as disclosed pursuant to the SEC’s compensation disclosure rules (which disclosure includes the following compensation tables and related material disclosed in this Proxy Statement).

In connection with our 2023 Annual Meeting of Stockholders (the “2023 Annual Meeting”), we submitted our executive compensation program to our stockholders for approval, on a non-binding, advisory basis (also known as “Say-on-Pay”). Approximately 86% of voting stockholders at the 2023 Annual Meeting approved our executive compensation program. The Compensation Committee reviews our executive compensation program annually to ensure it is aligned with our long-term business strategy and encourages the creation of long-term stockholder value. At the 2023 Annual Meeting, our stockholders also approved, on a non-binding, advisory basis, “every one year” for the frequency of the “say-on-pay” vote. The Compensation Committee considered such strong stockholder support as an endorsement of the Company’s executive compensation program and policies. The Compensation Committee values the opinions of our stockholders and will continue to consider those opinions when making future executive compensation decisions.

Our executive compensation program reflects the philosophy that compensation should reward executives for outstanding individual performance and, at the same time, align the interests of executives closely with those of stockholders. To implement that philosophy, the Company aims to reward above average corporate performance and recognize individual initiative and achievements. Our executive compensation program is designed to attract, retain, motivate, and reward key executives and align their interests with that of our stockholders. As such, we believe that our executive compensation program and the corresponding executive compensation detailed in this Proxy Statement are aligned with the long-term interests of our stockholders.

As an advisory vote, this proposal is not binding upon the Company. However, the Compensation Committee, which is responsible for designing and administering our executive compensation program, values the opinions expressed by stockholders in their vote on this proposal, and intends to consider the outcome of the vote when making future compensation decisions for our executive officers.

The Board strongly endorses the Company’s executive compensation program and recommends that stockholders vote in favor of the following resolution:

RESOLVED, that the stockholders approve, on a non-binding, advisory basis, the compensation paid to the Company’s named executive officers as disclosed pursuant to the compensation disclosure rules of the SEC, including the compensation tables and any related material disclosed in Global Self Storage’s Proxy Statement for the 2024 Annual Meeting of Stockholders.

We recognize that the quality, abilities and dedication of our named executive officers are critical factors that drive the long-term value of the Company. One of the primary objectives of the Compensation Committee is to ensure that the Company provides a competitive and comprehensive compensation program that allows us to attract and retain qualified and talented individuals who possess the skills and expertise necessary to lead, manage and grow the Company and who are accountable for the performance of the Company. The Compensation Committee, which is comprised entirely of Independent Directors, has the overall responsibility for monitoring the performance of our named executive officers and evaluating and approving our executive compensation plans, policies and programs.

The main elements of our executive compensation program include base salary, cash bonuses, and long-term equity compensation. Base salary is a critical element of executive compensation as it provides such executives with assured monthly cash compensation. Annual cash bonuses are also important to incentivize our executives to achieve short-term corporate strategic initiatives, to motivate certain desired individual behaviors, and to reward substantial achievement of these objectives and individual goals. In 2017, the Company engaged Willis Towers Watson (“WTW”), a globally recognized compensation

consultant, to advise and provide guidance to the Compensation Committee with respect to its existing executive compensation practices, and also to help develop and implement our ongoing executive compensation program that incorporates long-term equity compensation. Long-term equity compensation is central to our overall executive compensation program as it promotes retention and encourages the creation of long-term stockholder value and the achievement of our long-term business strategy.

As the Company seeks to continue to implement its growth plan and expand its underlying business, the Compensation Committee will continue to review and consider our executive compensation program to ensure that the Company provides a compensation program that attracts and retains the best executive talent in a manner that allows us to align the interests of our named executive officers with those of our stockholders.

The following table provides summary information concerning compensation paid or accrued by the Company to or on behalf of our named executive officers for services provided to the Company during the years ended December 31, 2022 and December 31, 2023. The Company has not granted or paid any option awards, nonequity incentive plan compensation, or nonqualified deferred compensation earnings to any of our named executive officers during the years ended December 31, 2022 and December 31, 2023.

As of December 31, 2023, M. Winmill, O’Malley, and Klimoski’s compensation plan generally consisted of base salary, employee benefits plan participation, qualified retirement plan participation, bonuses, stock grants, and certain prerequisites. A portion of M. Winmill, O’Malley, and Klimoski’s compensation may be deferred at their election.

Mark Winmill’s compensation as Chief Executive Officer and President of the Company is determined by the Compensation Committee and consists of a salary, bonus, employee benefits, and/or reimbursement of reasonable business expenses. The Compensation Committee reviews and approves corporate goals and objectives relevant to M. Winmill’s compensation, evaluates his performance relative to those goals and objectives, and sets his compensation annually.

Mark Winmill’s compensation is determined annually by the Compensation Committee by level of responsibility and tenure at the Company. For 2022 and 2023, the Board directed that non-CEO employee compensation (other than awards under the 2017 Equity Incentive Plan (our “Plan”), which are typically determined annually by the Compensation Committee), including Messrs. O’Malley’s and Klimoski’s, be set based on a general methodology used in prior years whereby the total level of compensation for each non-CEO employee that is concurrently employed by the Company and its Affiliates is set by Mark Winmill, as Chief Executive Officer of the Company and Tuxis, and Thomas Winmill, as Chief Executive Officer of other affiliates of the Company, and then allocated based on time allocation reports of each such non-CEO employee or other means deemed appropriate by Mark and Thomas Winmill.

The primary components of Mark Winmill, Thomas O’Malley, and Donald Klimoski’s bonuses are typically based on, among other things, (i) the number of weeks’ salary paid as bonuses to Company employees generally, and/or (ii) the financial performance of the Company. A subjective component of M. Winmill, O’Malley, and Klimoski’s bonuses may be based on their overall contribution to management of the Company.

Benefits consist of premiums paid by the Company for medical, dental, vision, life and long term disability insurances. The Company and its affiliates (as detailed below) participate in a 401(k) retirement savings plan for substantially all qualified employees. A matching expense based upon a percentage of contributions to the plan by eligible employees is incurred and allocated among the Company and its affiliates. The matching expense is accrued and funded on a current basis and may not exceed the amount permitted as a deductible expense under the Internal Revenue Code of 1986, as amended (the “Code”). The Company’s allocated matching expense to M. Winmill, O’Malley, and Klimoski under the plan was $15,709, $11,888 and $12,012, respectively, for the year ended December 31, 2023.

The Company currently reimburses monthly automobile expenses of $1,000 per month to its President, Mark C. Winmill. To the extent that the monthly payment under the Company’s automobile lease exceeds the current monthly reimbursement amount, M. Winmill voluntarily reimburses the Company for the excess amount. In this regard, M. Winmill has reimbursed the Company $8,198 for the automobile payments paid and due in 2023.

On March 27, 2023 and March 25, 2024, respectively, in consultation with WTW, the Compensation Committee approved awards under our Plan to our named executive officers and certain of our other officers, employees and independent contractors in respect of performance for the fiscal years ending December 31, 2023 and December 31, 2024, as further described below.

The awards approved on March 27, 2023, consisted of restricted share awards under our Plan to our named executive officers and certain of our other officers, employees and independent contractors in the aggregate amount of 37,976 shares, of which 23,726 shares are performance-based grants and the remainder of the shares are time-based grants. M. Winmill, O’Malley, and Klimoski, received 12,672, 5,527 and 5,527 shares, respectively. With respect to the grants made to M. Winmill, O’Malley, and Klimoski, 100% of the award is subject to annual performance conditions, and vest based on continued employment and the achievement of certain adjusted funds from operations (“AFFO”) and same store revenue growth (“SSRG”) goals by the Company during 2023. Between 0% and 200% of these shares were eligible to be earned based on achievement of the AFFO and SSRG goals in 2023, and the shares which were earned will remain subject to quarterly vesting during the remaining four-year time vesting period. In the event that the Company completed acquisitions in 2023 of a certain dollar amount or more, the number of performance shares earned by M. Winmill, O’Malley, and Klimoski in 2023 would have been increased by 25%. Dividends paid by the Company prior to the determination of the number of shares earned will be retained by the Company and released only with respect to earned shares.

M. Winmill, O’Malley, and Klimoski earned a weighted payout percentage of approximately 127.36% of such shares based on AFFO and SSRG in 2023. With respect to the grants made in 2023 to M. Winmill, O’Malley and Klimoski, 16,139 of the shares for M. Winmill and 7,039 of the shares for each of O’Malley and Klimoski will vest based on continued employment. Dividends paid by the Company prior to the determination of how many shares were earned were retained by the Company and released with respect to earned shares.

On March 25, 2024, the Compensation Committee approved restricted share awards under our Plan to our named executive officers and certain of our other officers, employees and independent contractors in the aggregate amount of 108,374 shares, of which 23,726 shares are performance-based grants and the remainder of the shares are time-based grants. The aggregate amount of shares granted in 2024 follows a multi-year long-term incentive plan with a three-year average annual issuance target of the Company's outstanding common stock, which has been in place since the Plan's inception in 2018. With respect to the grants

made to Messrs. Winmill, O’Malley, and Klimoski, 38,054 of the shares for Mr. Winmill, 16,422 of the shares for Mr. O’Malley and 16,422 of the shares for Mr. Klimoski vest solely based on continued employment, with 6.25% of the shares eligible to vest on each three-month anniversary of the grant date. These time-based restricted shares entitle the holder to dividends paid by the Company on shares of its common stock. Further, these time-based restricted share grants were front loaded and represented three years of grants, which follows the same multi-year long-term incentive plan paradigm that has been in place since the Plan's inception in 2018; therefore, no additional time-based grants are currently expected to be made in 2025 and 2026 to Messrs. Winmill, O’Malley and Klimoski. The remaining 12,672 of the shares for Mr. Winmill, 5,527 of the shares for Mr. O’Malley and 5,527 of the shares for Mr. Klimoski vest based on continued employment and the achievement of certain AFFO and SSRG goals by the Company during 2024. It is currently expected that performance-based grants such as these will be made to M. Winmill, O’Malley and Klimoski on an annual basis. Between 0% and 200% of these shares will be earned based on achievement of the AFFO and SSRG goals in 2024, and the shares which are earned will remain subject to quarterly vesting during the remaining four-year time vesting period. In the event that the Company completes acquisitions in 2024 of a certain dollar amount or more, the number of performance shares earned by M. Winmill, O’Malley, and Klimoski in 2024 shall be increased by 25%. Dividends paid by the Company prior to the determination of how many shares are earned will be retained by the Company and released only with respect to earned shares. If a Change in Control (as defined in our Plan) occurs during 2024, the number of shares earned will equal the greater of the number of shares granted and the number of shares which would have been earned based on the AFFO and SSRG through the date of the Change in Control. If following a Change in Control, a grantee is terminated by the Company without Cause or by the grantee with Good Reason (as each is defined in our Plan), all unvested restricted shares will fully vest.

The following table summarizes all outstanding equity awards held by our named executive officers on December 31, 2023.

(1) For purposes of this table, the market value of the restricted shares is deemed to be $4.635 per share, the closing price of the common stock reported on NASDAQ on December 29, 2023 (the last trading day of the year).

(2) Represents the unvested restricted shares granted on March 25, 2021 and outstanding on December 31, 2023, 6.25% of which vest quarterly solely based on the performance of services.

(3) Represents the number of unvested restricted shares granted on March 26, 2020, March 25, 2021, March 28, 2022, and March 27, 2023, respectively, and outstanding on December 31, 2023 that were eligible to vest at a rate of 6.25% per quarter based on the performances of services and upon attainment of “target” AFFO and SRRG goals in 2020, 2021, 2022 and 2023, respectively, as described immediately below.

The following table sets forth the fiscal year 2023 AFFO and SSRG performance vesting targets for the restricted shares granted on March 27, 2023 that vest based on continued employment and achievement of AFFO and SSRG goals.

(1) In the event AFFO falls between shown points, the payout percentage for the AFFO shares is determined using a straight line linear interpolation.

(2) In the event SSRG falls between shown points, the payout percentage for the SSRG shares is determined using a straight line linear interpolation.

(3) Reflects the weighted payout percentage for the AFFO shares and the SSRG shares.

For 2023, the Company’s AFFO was $4,383,769 and SSRG was 2.1%, which, with each weighted equally, resulted in vesting of 127.36% of the target number of performance vesting restricted shares (a total of 16,139, 7,039 and 7,039 shares for M. Winmill, O’Malley and Klimoski, respectively). As of March 31, 2024, twenty-five percent of these shares were vested and the remainder will vest quarterly in 6.25% increments based on continued employment.

Pay Versus Performance

As discussed above, the Compensation Committee has implemented an executive compensation program designed to link a substantial portion of our executives' compensation to the achievement of the Company’s financial, operational and strategic objectives.

On March 25, 2024, the Company entered into a second amended and restated employment agreement (the Agreement") with its Chief Executive Officer and President, Mark C. Winmill.

The Agreement has an initial term of three years and is subject to automatic one-year extensions thereafter, unless either party provides at least 90 days’ notice of non-renewal.

The Agreement provides that, if Mr. Winmill’s employment is terminated by the Company without “cause” or by Mr. Winmill for “good reason” (each as defined in the Agreement), or as a result of the Company’s notice of non-renewal of the employment term, Mr. Winmill will be entitled to the following severance payments and benefits, subject to the execution and non-revocation of a general release of claims:

In the event Mr. Winmill’s employment terminates by reason of his death or disability he or his estate shall receive:

The Agreement contains standard confidentiality provisions, which apply indefinitely, and both non-competition and non-solicitation of employees and customers covenants, which apply during the term of employment and for a period of twelve months thereafter.

Our Plan is designed to provide equity-based incentives to certain eligible persons, as defined in our Plan, in the form of options, share appreciation rights, restricted shares, restricted share units, dividend equivalent rights or other forms of equity-based compensation as determined in the discretion of the Board, the Compensation Committee, or other designee thereof. For additional information about our Plan, see “–2017 Equity Incentive Plan” below.

The following table presents certain equity compensation plan information as of December 31, 2023:

The purpose of our Plan is to provide us with the flexibility to use stock options and other equity-based awards to provide a means of performance-based compensation.

Key employees, directors, officers, advisors, consultants, and other personnel of ours and our subsidiaries, and other persons expected to provide significant services to us or our subsidiaries, are eligible to be granted incentive and nonqualified share options, share appreciation rights, restricted shares, restricted share units, dividend equivalent rights, and other forms of equity-based compensation under our Plan.

The Compensation Committee has the authority to administer and interpret our Plan, to authorize the granting of awards to eligible participants, to determine the eligibility of eligible participants to receive an award, to determine the number of shares of common stock to be covered under each award agreement, considering the position and responsibilities of the eligible participants, the nature and value to us of the eligible participants’ present and potential contribution to our success, whether directly or through our subsidiaries, and such other factors as the Compensation Committee may deem relevant, to approve the form of award agreement, to determine the terms applicable to each award, which may differ among individual awards and participants, and may include performance goals, to extend at any time the period in which options or share appreciation rights may be exercised, provided that such awards cannot have a term longer than 10 years, to determine the extent to which the transferability of shares issued or transferred pursuant to an award is restricted, to decide all disputes arising in connection with our Plan, and to take any other actions, make all other determinations that it deems necessary or appropriate, and otherwise supervise the administration of our Plan.

Our Plan has been administered by a Compensation Committee consisting of two or more non-employee directors, each of whom is intended to be, to the extent required by Rule 16b-3 under the Exchange Act, a non-employee director and will, at such times as we are subject to Section 162(m) of the Code, qualify as an "outside director" for purposes of Section 162(m) of the Code.

Subject to adjustment upon certain corporate transactions or events, a maximum of 760,000 shares of common stock may be subject to share options, share appreciation rights, restricted shares, restricted share units, dividend equivalent rights, and other forms of equity-based compensation awards under our Plan. If an option or other award granted under our Plan is cancelled, expires or terminates, the shares that expire or terminate without having been exercised or paid, as the case may be, will again become available for the issuance of additional awards. In addition, shares subject to any restricted share unit, dividend equivalent right or other equity-based award (other than share options and share appreciation rights) that are settled in cash will again become available for the issuance of additional awards. Furthermore, awards granted in substitution, assumption, continuation or adjustment of awards remaining available for grant under our Plan pursuant to a change in control or other corporate transaction will not count against the number of shares remaining available for issuance under our Plan. The shares available under a stockholder-approved plan of an entity acquired by us will be available for awards granted to individuals who were not employees of ours immediately before such acquisition, and will not count against the number of shares remaining available for issuance under our Plan. Unless previously terminated by the Board, no new award may be granted under our Plan after October 16, 2027.

Under Section 6 of Article II of the Company’s bylaws, a majority of the votes cast at a meeting of stockholders duly called and at which a quorum is present is sufficient to approve any matter which may properly come before the Meeting, unless more than a majority of the votes cast is required by statute or the Company’s charter. Inasmuch as Proposal 3 does not require a greater vote by statute or the Company’s charter, a majority of all the votes cast at the Meeting at which a quorum is present is sufficient to approve this Proposal 3. Abstentions and broker non-votes are not votes cast and will have no effect on the result of the vote on this proposal, although they will be considered present for the purpose of determining the presence of a quorum. Proxies solicited by the Board will be voted "FOR" this proposal, unless otherwise instructed.

The following table sets forth certain information with respect to the beneficial ownership of our common stock as of April 8, 2024 for:

We have determined beneficial ownership in accordance with the rules of the SEC including, but not limited to, Section 13(d)(3) of the Exchange Act. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power. There are no shares of common stock subject to options or other rights exercisable outstanding as of the date of this Proxy Statement. Except as indicated in the footnotes below, we believe, based on the information furnished to us, that the persons and entities named in the table below have sole or shared voting and investment power with respect to all of the common stock that they beneficially own.

Applicable percentage ownership is based on 11,260,557 shares of common stock outstanding as of April 8, 2024. Unless otherwise indicated, the mailing address of each beneficial owner in the table is: Global Self Storage, Inc., 3814 Route 44, Millbrook, New York 12545.

* Represents beneficial ownership of less than 1.00% of the outstanding shares of common stock.

There are no currently proposed transactions nor have there been any transactions during the Company’s last two fiscal years in which the Company was or is to be a participant and the amount involved exceeds $120,000, and in which any related person (as defined in Item 404 of Regulation S-K of the Exchange Act) had or will have a direct or indirect material interest, except for the transactions described below. The Company has not had a promoter at any time during the past five fiscal years and does not have a parent.

Certain officers and directors of the Company also serve as officers and/or directors of Winco, Bexil, Tuxis, and/or their affiliates (collectively with the Company, the “Affiliates”). As of April 8, 2024, certain of the Affiliates and the Company’s directors and employees may be deemed to own approximately 9.1% of the Company’s outstanding common stock. There may be conflicts of interest resulting from the relationships among the Company, the Affiliates, and other related parties. The outside business interests of the Company’s officers may divert their time and attention away from the Company, and may result in a potential conflict with respect to the allocation of business opportunities, which could harm its business. The Board has adopted policies and procedures designed to mitigate these conflicts of interest, such as allocation procedures for determining the appropriate allocation of such business opportunities. Specifically, if any officer or director of the Company who also serves as an officer, director, or advisor of the Affiliates becomes aware of a potential transaction related primarily to the self storage business that may represent a business opportunity for the Company and one or more of the Affiliates, such officer or director has no duty to present that opportunity to such Affiliates and the Company will have the sole right to pursue the transaction if the Board so determines. Notwithstanding the foregoing, officers or directors of the Company are encouraged to notify the Affiliates of such an opportunity.

Pursuant to an arrangement between a professional employer organization (“PEO”) and the Affiliates, the PEO provides payroll, benefits, compliance, and related services for employees of the Affiliates in accordance with applicable rules and regulations under the Code and, in connection therewith, Midas Management Corporation (“MMC”), a subsidiary of Winco, acts as a conduit payer of compensation and benefits to the Affiliates’ employees including those who are concurrently employed by the Company and its Affiliates. The aggregate compensation and benefits accrued and paid by the Company to MMC were $2,883,067 and $2,465,326 for the years ended December 31, 2023 and 2022, respectively. Expenses for various concurrently used administrative and support functions incurred by the Affiliates are allocated at cost among them. The aggregate administrative and support function expenses accrued and paid by the Company to Winco were $31,243 and $24,183 for the years ended December 31, 2023 and 2022, respectively. The Affiliates participate in a 401(k) retirement savings plan for substantially all qualified employees. A matching expense based upon a percentage of contributions to the plan by eligible employees is incurred and allocated among the Affiliates. The matching expense is accrued and funded on a current basis and may not exceed the amount permitted as a deductible expense under the Code. The Company's allocated matching expense was $102,219 and $87,238 for the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023 and 2022, the Company had reimbursements payable to MMC and Winco for compensation, benefits, and administrative and support function expenses of $23,523 and $16,835, respectively.

The Company currently reimburses monthly automobile expenses of $1,000 per month to its President, Mark C. Winmill. To the extent that the monthly payment under the Company’s automobile lease exceeds the current monthly reimbursement amount, Mr. Winmill voluntarily reimburses the Company for the excess amount. In this regard, Mr. Winmill has reimbursed the Company $8,198 and $1,878 for the automobile payments paid and due in 2023 and 2022, respectively.

The Company leases office space and storage to certain Affiliates under rental agreements. The terms of occupancy are month to month and automatically renew unless terminated by either party on thirty days’ written notice. The Company earned rental income of $4,800 and $18,000 for the years ended December 31, 2023 and December 31, 2022, respectively.

During 2020, MMC (the “Borrower”) entered into a Paycheck Protection Program Term Note (“PPP Note”) with Customers Bank on behalf of itself and the Affiliates under the Paycheck Protection Program of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) administered by the U.S. Small Business Administration (the “SBA”). The Borrower received total

proceeds of $486,602 from the PPP Note of which $307,210 was attributable to the Company under the SBA’s loan determination formula. In accordance with the requirements of the CARES Act, the Affiliates used the proceeds from the PPP Note primarily for payroll and other eligible costs. On April 5, 2022, the Borrower was granted forgiveness of the entire PPP Note and any accrued interest. Upon forgiveness, the Company received $307,210 in cash from the borrower, which was the amount attributable to the Company under the SBA's loan determination formula, and recorded a gain for such amount, in its consolidated statements of operations and comprehensive income.

All costs of soliciting proxies for the Meeting will be borne by the Company. In addition to the solicitation of proxies by use of the mail, directors and officers of the Company may solicit proxies by telephone, electronic communications, or personal contact, for which they will not receive any additional compensation. The Company may pay persons holding shares of its stock in their names or those of their nominees for their expenses in sending soliciting materials to their beneficial owners. Authorizations to execute proxies may be obtained by telephonic instructions in accordance with procedures designed to authenticate the stockholder’s identity. Stockholders requiring further information with respect to telephonic voting instructions may call toll-free at (800) 690-6903. Any stockholder giving a proxy may revoke it at any time before it is exercised by submitting to the Secretary of the Company a written notice of revocation or a subsequently executed proxy.

Stockholders are entitled to one vote for each share held, and a fractional vote for each fractional share held. Shares represented by executed and unrevoked proxies will be voted in accordance with the instructions on the proxy card. If a stockholder has signed a proxy card but no instructions are indicated, the proxies will vote “FOR” each proposal and, in their discretion, upon such other matters as may properly come before the Meeting. A stockholder may revoke a proxy by delivering to the Company’s Secretary, Donald Klimoski II, Esq. Global Self Storage, Inc., 3814 Route 44, Millbrook, New York 12545, a properly executed proxy with a date later than the previously delivered proxy or by sending a written revocation to the Company. To be effective, such revocation must be received prior to the Meeting. In addition, any stockholder who attends the Meeting virtually may vote by ballot at the Meeting, thereby canceling any proxy previously given.

The presence virtually or by proxy of stockholders entitled to cast a majority of all the votes entitled to be cast at the Meeting shall constitute a quorum. If a quorum is not present at the Meeting, the chairman of the Meeting has the power to adjourn the Meeting from time to time to a date not more than 120 days after the original record date without notice other than announcement at the Meeting. At a reconvened Meeting, if a quorum is present, any business may be transacted that might have been transacted at the originally scheduled Meeting. A stockholder vote may be taken for one or more proposals prior to any adjournment if sufficient votes have been received for approval. If a proxy is properly executed and returned accompanied by instructions to withhold authority to vote, represents a broker “non-vote” (that 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 of stock of the Company on a particular matter with respect to which the broker or nominee does not have discretionary power) or is marked with an abstention (collectively, “abstentions”), shares represented thereby will be considered to be present at the Meeting for purposes of determining the existence of a quorum for the transaction of business. Under Maryland law, abstentions are not votes cast and will have no effect on the results of the votes on Proposals 1 through 4. Because directors will be elected by a plurality of the votes cast in the election of directors, and no additional nominations may properly be presented at the Meeting, “withhold” votes will have no effect on the result of the vote on Proposal 1.

No other business is expected to be acted upon at the Meeting other than as described in this Proxy Statement. If any other matters properly come before the Meeting, shares represented by proxies will be voted in the discretion of the person or persons holding the proxies.

The Board knows of no other matters or business to be presented for consideration at the Meeting. If, however, any other matters properly come before the Meeting or any adjournments or postponements thereof, it is the intention of the persons named in the enclosed proxy to vote such proxy in accordance with their discretion on any such matters. The persons named in the enclosed proxy may also, if they deem it advisable, vote such proxy to adjourn the Meeting from time to time.

In accordance with the rules established by the SEC, any stockholder proposal submitted pursuant to Rule 14a-8 under the Exchange Act intended for inclusion in the Company’s proxy statement for the 2025 Annual Meeting of Stockholders (the “2025 Annual Meeting”) must be received by the Company no later than 120 days before the anniversary of the date of this proxy statement (e.g., not later than December 27th). Such proposals should be sent in writing to Global Self Storage, Inc., Attn: Donald Klimoski II, Esq., Senior Vice President - Operations, General Counsel, Secretary, and Chief Compliance Officer, 3814 Route 44, Millbrook, New York 12545. Such proposals must comply with Rule 14a-8 of the Exchange Act and the interpretations thereof, and may be omitted from the Company’s proxy materials for the 2025 Annual Meeting if such proposals are not in compliance with applicable requirements of the Exchange Act and the interpretations thereof.

The Company’s current bylaws also establish advance notice procedures for stockholder proposals and director nominations that are not submitted for inclusion in the Company’s proxy statement for the 2025 Annual Meeting. Pursuant to the Company’s current bylaws, a stockholder of record may nominate a candidate for election as a director at an annual meeting of stockholders or propose business for consideration at such meeting, provided that a proper advance written notice is timely submitted to the Company in accordance with the disclosure, procedural, and other requirements set forth in the Company’s current bylaws. To be timely submitted, a stockholder’s notice must be delivered to the Secretary of the Company, at its principal executive offices, no earlier than the 150th day nor later than 5:00 p.m., Eastern time, on the 120th day prior to the first anniversary of the date of the proxy statement for the preceding year’s annual meeting. Accordingly, pursuant to such bylaws, a record stockholder nomination or proposal intended to be considered at the 2025 Annual Meeting must be delivered and received by the Secretary of the Company no earlier than November 27, 2024, nor later than 5:00 p.m., Eastern time, on December 27, 2024. Stockholder notices of proposals and/or director nominations should be sent to Global Self Storage, Inc., Attn: Donald Klimoski II, Esq., Senior Vice President - Operations, General Counsel, Secretary, and Chief Compliance Officer, 3814 Route 44, Millbrook, New York 12545.

In addition to the above requirements for stockholder proposals and director nominations, the stockholder proponent or a qualified representative must attend the 2025 Annual Meeting to present such proposal or nomination.

Stockholders and other interested parties who wish to communicate with members of the Board or a specified member of the Board should submit the communication in writing to Global Self Storage, Inc., Attn: Donald Klimoski II, Esq., Senior Vice President - Operations, General Counsel, Secretary, and Chief Compliance Officer, 3814 Route 44, Millbrook, New York 12545, identifying the correspondence as intended for the Board, a specified member of the Board, or a specified group of directors.

For future stockholder meetings, you may request separate copies of these materials or request that we send only one set of these materials to you if you are receiving multiple copies by calling or writing to us at the number or address given above.

Please advise the Company’s transfer agent, Equiniti Trust Company, LLC, at (800) 937-5449, whether other persons are the beneficial owners of the shares of stock for which proxies are being solicited and, if so, the number of copies of this Proxy Statement and other soliciting material you wish to receive in order to supply copies to the beneficial owners of shares.
