    EXPLANATORY NOTE
    Whitestone REIT (also referred to herein as “we,” “our,” “us,” “Whitestone” and the “Company”) filed its Annual Report on Form
    10-K
    for the fiscal year ended December 31, 2025 (the “Original Filing”) with the Securities and Exchange Commission (the “SEC”) on March 6, 2026. We are filing this Amendment No. 1 to the Original Filing (the “Amended Filing”) solely for the purpose of including in Part III the information that was to be incorporated by reference from our definitive proxy statement for our 2026 Annual Meeting of Shareholders (the “2026 Annual Meeting”). Additionally, this Amended Filing hereby amends and restates the cover page of the Original Filing to remove the statement that information is being incorporated by reference from our definitive proxy statement.
    In addition, as required
    by
    Rule
    12b-15
    under the Securities Act of 1934, as amended, this Amended Filing also contains new certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, as amended. Accordingly, Item 15 of Part IV has also been amended and restated in its entirety to include the currently dated certifications as exhibits, and to reference the consolidated financial statements previously filed with the Original Filing. Because no consolidated financial statements have been included in this Amended Filing and this Amended Filing does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation
    S-K,
    paragraphs 3, 4 and 5 of the certifications have been omitted. Item 15 of Part IV has been amended and restated to include two additional material agreements pursuant to Item 601(b)(10) of Regulation
    S-K
    which were inadvertently omitted from the Original Filing. Exhibit 21.1 has also been amended to correct the list of our subsidiaries pursuant to
    Rule 1-02(w)
    of Regulation
    S-X.
    No other information in the Original Filing is amended hereby.
    In
    connection
    with the entry into an Agreement and Plan of Merger with certain Ares Real Estate funds, we deferred
    the
    2026 Annual Meeting, and the information that was previously contemplated to be incorporated by reference to our definitive proxy statement for the 2026 Annual Meeting is included in this Amended Filing.
    Except for the foregoing amended information or where otherwise noted, this Amended Filing does not reflect events that occurred after the Original Filing or modify or update those disclosures affected by subsequent events. This Amended Filing should be read in conjunction with the Original Filing.
    Cautionary Statement Regarding Forward-Looking Statements
    This Amended Filing contains forward-looking statements, which include all statements that do not relate solely to historical or current facts, such as statements regarding our expectations, intentions or strategies regarding the future. In some cases, you can identify forward-looking statements by the following words: “aim,” “anticipate,” “believe,” “can,” “continue,” “could,” “estimate,” “expect,” “forecast,” “goal,” “guidance,” “intend,” “may,” “plan,” “possible,” “potential,” “predict,” “project,” “ongoing,” “outlook,” “should,” “seek,” “target,” “will,” “would,” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. The forward-looking statements speak only as of the date they are made. Whitestone undertakes no obligation to update or review any forward-looking statements, except as required by law, whether as a result of new information, future events or otherwise.

    Audit Committee
    The primary purposes of the Audit Committee are overseeing our accounting and financial reporting process, the audits of our financial statements; and assisting the Board in its oversight of the following:
     
      i.
    management’s responsibilities to assure there is in place an effective system of internal controls over financial reporting;
     
      ii.
    the qualifications and independence of our independent registered public accounting firm;
     
      iii.
    the performance of our independent registered public accounting firm; and
     
      iv.
    our compliance with our ethical standards, policies, plans and procedures, and applicable laws and regulations.
    The committee also prepares a report each year for inclusion in our proxy statement in accordance with the rules of the SEC.
    The committee currently consists of Julia B. Buthman, Amy S. Feng, Kristian M. Gathright, and Jeffrey A. Jones, with Mr. Jones serving as chair. Our Board has determined that all of the members of the committee are an “audit committee financial expert” as defined by the rules promulgated by the SEC. Each member of the committee is “independent” under the NYSE listing standards and applicable SEC rules.
    Code of Business Conduct and Ethics
    Our Board has adopted a Code of Business Conduct and Ethics that is applicable to all members of our Board, our executive officers and our employees. According to our Code of Business Conduct and Ethics, our employees and trustees are expected to exhibit and promote the highest standard of honest and ethical conduct, by their adherence to the following policies and procedures: (1) they shall engage in only honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships; and (2) they shall inform our General Counsel of any deviations in practice from policies and procedures governing honest and ethical behavior or any material transaction or relationship that comes to their attention that could reasonably be expected to create a conflict of interest.

    Table of Contents
    If we amend or grant any waiver from a provision of our Code of Business Conduct and Ethics, we will promptly disclose such amendment or waiver in accordance with and, if required by applicable law, including by posting such amendment or waiver on our website at the address above. The Audit Committee oversees compliance with our Code of Business Conduct and Ethics. Our Code of Business Conduct and Ethics is available under the “Corporate Governance” page of our website at www.whitestonereit.com.
    Clawback Policy
    As required by the SEC and NYSE listing standards, our Board has adopted a Clawback Policy that permits us to recover incentive compensation from certain officers in the event we are required to prepare a financial restatement, without regard to whether the restatement is caused by wrongdoing, negligence, or other misconduct. Our Clawback Policy is available on our website at http://ir.whitestonereit.com/.
    Insider Trading Compliance Policy
    Our Board has adopted an Insider Trading Compliance Policy which prohibits our trustees and executive officers from engaging in insider trading, executing, “short sales,” purchasing any financial instrument or entering into any transaction that is designed to hedge or offset any decrease in the market value of our shares or other equity securities granted as compensation or held directly or indirectly (“Securities,”) purchasing or selling derivative securities related to our Securities, or pledging Securities as collateral for indebtedness, including holding such shares in a margin account.
    Board Leadership Structure
    The roles of Chair of the Board and Chief Executive Officer are separate. Our Chair of the Board is an independent trustee. Our independent trustees meet separately in executive sessions on a regular basis, typically during a portion of, or immediately after, each regularly scheduled meeting of our Board. Ms. Feng, our independent Chair presides over executive sessions of the independent trustees. The Board believes that its current leadership structure is appropriate for us because it separates the leadership of the Board from the
    day-to-day
    leadership of the Company. The Board also believes that separating the position of Chair from Chief Executive Officer better positions the Board to evaluate the performance of management and enables the Chair to provide guidance to the Chief Executive Officer.
    The duties of the Chair include the following:
     
      •  
    presiding at meetings of the Board, including executive sessions of the independent trustees;
     
      •  
    previewing the information to be provided to the Board;
     
      •  
    approving meeting agendas for the Board;
     
      •  
    assuring that there is sufficient time for discussion of all meeting agenda items;
     
      •  
    organizing and leading the Board’s evaluation of the CEO; and
     
      •  
    being responsible for leading the Board’s annual self-assessment.

    Risk Management
    Our Board has an active role, as a whole and also at the committee level, in overseeing management of our risks. Our Board regularly reviews information regarding our credit, liquidity and operations, as well as the risks associated with each. The Compensation Committee is responsible for overseeing the management of risks relating to our executive compensation plans and arrangements, as more fully described in “Compensation Discussion and Analysis-Compensation Related Risk Management.” The Audit Committee oversees management of financial and legal compliance risks. The Nominating and Corporate Governance Committee manages risks associated with the independence of the Board and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports about such risks. Specific actions that have been taken by the Board include:
     
      •  
    Expenditures for capital projects, tenant improvements and lease commissions, and general invoices of over $3.0 million require Board approval;
     
      •  
    The board reviews and approves all acquisition and disposition decisions over $5 million; and
     
      •  
    A compliance policy regarding insider information, disclosure of
    non-public
    information and limitation on employee and trustee transactions of our shares.
    The Audit Committee considers risks relating to cybersecurity and, for that purpose, receives regular reports from management regarding cybersecurity risks and countermeasures being undertaken or considered by us, including updates on the internal and external cybersecurity landscape and relevant technical developments.
    The Board believes that the administration of its risk oversight function has not affected its leadership structure.
    Communications with our Board of Trustees
    We have established procedures for shareholders or other interested parties to communicate with our Board, including our independent trustees. Such parties can contact the Board by sending a letter to:
     Whitestone REIT, Attn: Peter Tropoli, Corporate Secretary, 2600 South Gessner Road, Suite 500, Houston, Texas 77063
    . Our Corporate Secretary will review all communications made by this means and forward the communication to our Board or to any individual trustee to whom the communication is addressed.

    Say-On-Pay Results and Shareholder Engagement
    Our Board and our Compensation Committee value the opinions of our shareholders and are committed to ongoing engagement with our shareholders on executive compensation practices. The Compensation Committee specifically considers the results from the annual shareholder advisory vote on executive compensation. At the 2025 annual meeting of shareholders, approximately 91% of the votes cast on the shareholder advisory vote on our executive compensation proposal were in favor of our executive compensation. We believe the results of the 2025 say-on-pay vote demonstrate continued strong shareholder support for our current compensation programs.
    Our Performance—2025
    The information presented below demonstrates that our NEOs accomplished significant goals on behalf of our shareholders in 2025. We believe these results are due to the alignment between our NEOs’ interests and those of our shareholders through our executive compensation plans, including the 2018 Plan, under which we predominantly issue performance-based equity grants. We believe the information in this Compensation Discussion and Analysis (“CD&A”) also demonstrates that our compensation program is commensurate with our growth and follows best practices in our industry.
    In 2025, we accomplished the following:
     
      •  
    Revenues of $160.9 million versus $154.3 million for 2024;
     
      •  
    Net Income attributable to common shareholders of $49.9 million, or $0.95 per diluted share, inclusive of a $0.57 per diluted share gain on sale of properties, versus $36.9 million, or $0.72 per diluted share, inclusive of a $0.43 per diluted share gain on sale of properties for 2024;
     
      •  
    Funds from Operations (“FFO”) of $54.6 million versus $50.7 million for 2024;
     
      •  
    Fourth Quarter Annualized Pro Forma EBITDAre of $96.3 million versus $92.0 million for 2024; and
     
      •  
    Same-Store Net Operating Income of $97.5 million versus $93.8 million for 2024.
    FFO, FFO Per Share, EBITDAre, the Ratio of Debt to Pro Forma EBITDAre and Same Store Net Operating Income (“NOI”) are financial measures that are not calculated pursuant to U.S. generally accepted accounting principles (“GAAP”). Please refer to APPENDIX
    A—NON-GAAP
    MEASURES for explanations and reconciliations of these metrics to their most comparable GAAP metric.
    2025 Pay for Performance Decisions
    The following table summarizes the decisions of the Compensation Committee in 2025 versus 2024. Our compensation philosophy is to pay at market median, with the majority of executive pay being aligned with our performance. When our performance and individual performance warrants, we may compensate above the market midpoint in variable pay components. Our independent compensation consultant analyzed the 2025 compensation changes vs. the peer group and concluded the named executive officers’ 2025 total actual compensation was aligned between the 25th and 50th percentile of the peer group. We expect the NEO total actual compensation to move to the 50th percentile over time.

    In 2025, Ms. Mastandrea and Ms. Siv achieved 97% and 94%, respectively and Messrs. Holeman, Hogan and Tropoli, achieved 90%, 94% and 94%, respectively of their annual cash incentive targets. All 2025 incentive amounts were paid in March 2026. The amount reflected in the 2024 Annual Cash Incentive column includes a retention payment of $375,000 and $240,000 for Mr. Holeman and Ms. Mastandrea, respectively, that was awarded on February 10, 2021, earned on December 31, 2024 and paid in March 2025. Further discussion of the annual cash incentive targets and actions is contained in “
    Compensation Strategy and Philosophy
    .”
    Summary of Our Compensation Practices
    The Compensation Committee’s charter specifies its responsibility for establishing, implementing and continually monitoring our executive compensation programs. Additionally, the Compensation Committee is responsible for the assessment of executive compensation relative to our performance, ensuring that the application of our compensation plans to specific executive incentive awards is justifiably appropriate, and making all compensation-related recommendations to our Board.
    The material presented in this CD&A discusses (1) our executive compensation philosophy, strategy, process and procedures which are centered on a
    pay-for-performance
    philosophy and take into consideration the entrepreneurial approach required of our NEOs to build us and (2) all compensation components for our five NEOs, including a summary of the following:

    Compensation Best Practices that We Follow
    Pay for Performance—
    We tie pay to performance. In 2025, 70% of our NEOs’ targeted pay was “at risk.” We set clear financial goals for corporate performance and differentiate based on individual achievement. In establishing goals, we select performance metrics that drive both our short-term and long-term corporate strategy in accordance with our strategic plan.
    Performance Based Long-Term Incentives -
    For our 2025 awards, 70%, 70%, 65%, 65% and 60% of the grant vests based on relative TSR over a three-year performance period for Mr. Holeman, Ms. Mastandrea, Mr. Hogan, Mr. Tropoli and Ms. Siv, respectively, and 30%, 30%, 35%, 35% and 40%, vests based on continued employment over three years for Mr. Holeman, Ms. Mastandrea, Mr. Hogan, Mr. Tropoli and Ms. Siv, respectively. We believe this balance allows us to retain and attract key personnel and aligns those individuals with the interests of shareholders.
    Formulaic Short-Term Incentives
    –75% of the NEOs’ annual incentive awards are based on rigorous objectively-determinable company goals established and approved by the Compensation Committee. 25% is based on the discretion of the Compensation Committee.
    Mitigate Undue Risk—
    We mitigate undue risk associated with compensation, including utilizing caps on potential payments, retention provisions, multiple performance targets, equity ownership guidelines and robust Board and management processes to identify risk.
    Independent Compensation Consulting Firm
    —The Compensation Committee utilizes an independent compensation consulting firm, which provides no other services to us.
    Minimal Perquisites—
    We provide minimal perquisites to our executive officers.
    Regular Review of Share Utilization
    -
    Annually, we evaluate share utilization by reviewing overhang levels (dilutive impact of equity compensation on our shareholders) and annual run rates (the aggregate shares awarded as a percentage of total outstanding shares) to limit dilution to our shareholders while providing adequate market competitive compensation to employees.
    Equity Ownership Guidelines
    —We require our trustees and NEOs to acquire and maintain prescribed levels of ownership of our shares in order to align their interests with those of our shareholders.
    Review NEO Total Compensation
    - We compare the total compensation of our NEOs to that of our peers prior to making executive compensation decisions.
    Negative Compensation Practices That We Do Not Follow
    Excise Tax
    Gross-Ups
    upon Change in Control
    Repricing of Underwater Options
    Severance Multipliers Greater Than 3X
    Automatic Share Reload (“Evergreen”) feature in Equity Incentive Plan

    Compensation Strategy and Philosophy
    Our corporate business model is based on the creation of Community Centered Properties
    ®
    that are carefully tenanted and positioned to add value to the communities in which they are located. Our business model is entrepreneurial, involves a high degree of long-term planning, strategic thought and careful execution so that our properties effectively function as communities.
    In allocating compensation, we believe the compensation of senior levels of management should be predominantly performance-based since these levels of management have the greatest ability to influence corporate performance. The table below summarizes the allocation of the 2025 compensation opportunity for our NEOs and all other executives based upon the three primary elements of compensation—base salary, annual cash incentive, and long-term incentives.
    We generally aim to align with the market in each of the three pay elements as defined in our
    pay-for-performance
    philosophy.
    The three elements of 2025 compensation are discussed in detail below.
    Base Salary
    . The Compensation Committee’s philosophy is to pay for performance, setting base salaries at the market median. Our independent compensation consultant analyzed the NEOs’ 2024 compensation compared to the peer group and concluded the NEOs’ 2025 base salaries were slightly above the 25th percentile of the peer group.

    Annual Cash Incentive
    . Our NEOs are eligible to receive annual cash incentive awards under our annual incentive program (the “AIP”). The AIP provides an opportunity for employees to receive a short-term award based on the achievement of specified organization, operating and financial goals and objectives at the corporate level that are established by the Compensation Committee each year.
    The 2025 target incentive opportunities granted to the NEOs under the AIP were as follows:

    94% of the target amount under the AIP. All amounts were paid to the NEOs in March of 2025.
    Long-Term Equity Incentive Ownership Plan
    . The 2018 Long-Term Equity Incentive Ownership Plan (the “2018 Plan”) became effective on July 30, 2018. The 2018 Plan provides for equity-based grants of incentive compensation to our NEOs and other employees and provides an opportunity for our employees to receive grants of equity that vest over time or upon the achievement of long-term goals that create incremental value for us and our shareholders.

    Table of Contents
    The 2018 Plan is designed to encourage entrepreneurship and align the interests of our NEOs and employees with our long-term strategy. The Compensation Committee considers these awards to be the most important component of total compensation and key retention of participants because they encourage participants to think and act like owners. Our independent compensation consultant analyzed the 2025 compensation compared to the peer group and concluded that the grant date fair value of our NEOs’ 2025 target long-term incentive awards were at the 40th percentile of our peer group.
     
      •  
    For 2025, 70%, 65%, 65%, 70%, 60% of, the restricted common share units granted under the 2018 Plan to Messrs. Holeman, Hogan and Tropoli and Ms. Mastandrea and Siv, respectively, vest based on our TSR relative to that of the peer group defined in the award agreements over a three-year performance period from January 1, 2025 through December 31, 2027 (the “TSR Units”). At the end of the performance period, the number of common shares awarded will be a multiple of the number of units granted based on our ranking in the peer group (the “TSR Peer Group Ranking”) as shown in the table below. Continued employment is required through the end of the performance period.
     
      •  
    The remaining percentage of each NEO’s restricted common share units granted in 2025 under the 2018 Plan vest based on continued employment over three years. Vesting occurs annually over the three years in equal increments on June 30, 2026, 2027 and 2028 (the “Time-Based Units”).

    The grant date fair value for each Time-Based Unit of $11.48 was determined in accordance with ASC Topic 718, utilizing the assumptions discussed in Note 14 to our audited financial statements for the year ended December 31, 2025 as included in the Original Report. The grant date fair value for each TSR Unit of $10.40 was determined using the Monte Carlo simulation method and is being recognized as share-based compensation expense ratably from the June 30, 2025 grant date to the end of the performance period, December 31, 2027. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award grant and calculates the fair value of the award. Expected volatilities utilized in the model were estimated using a historical period consistent with the performance period of approximately three years. The risk-free interest rate was based on the United States Treasury rate for a term commensurate with the expected life of the grant.
    Compensation Objectives
     
    Objective
      
    Compensation Elements Designed to Meet Objective
    Compensation should be linked to performance.
       A significant portion of each NEO’s pay opportunity relates to the performance-based awards granted pursuant to the 2018 Plan, which will vest based on achievement of performance targets.
    Compensation should be fair and competitive.
       We believe that our compensation is fair and competitive and generally aligns between the 25th and 50th percentile of our peer group. Over time we expect to align with the 50th percentile. A significant portion of our NEOs’ compensation is at risk and is expected to be in the form of long-term awards.
    Executive share ownership is required.
       Our long-term incentive award program is a key means by which executives are rewarded for financial performance. As the awards vest, we expect our executives will retain a significant number of their vested shares in accordance with our share ownership guidelines. As of December 31, 2025, all NEOs had satisfied the share ownership guidelines.
    The Compensation Committee and the Board exercise
    independent judgment.
       On behalf of our shareholders, the Compensation Committee and the Board ensure that executive compensation is appropriate and effective, and that all assessments, engagement of advisors, analysis, discussion, rationale and decision making are through the exercise of independent judgment.

    Roles and Responsibilities in Compensation Decisions
    The Compensation Committee is specifically responsible for compensation decisions related to our CEO. The Compensation Committee reviews, assesses and approves recommendations from our CEO regarding any determination of base salary and annual cash incentives to all other officers, including the other NEOs. The Compensation Committee’s philosophy and strategy and the programs adopted by our Board establish the general parameters within which our CEO recommends compensation for the other NEOs.
    David K. Holeman, our Chief Executive Officer, annually reviews the performance of our other officers. The conclusions reached and recommendations made based on these reviews, including base salary adjustments as well as annual cash incentives, are presented to the Compensation Committee. The Compensation Committee can exercise its discretion in modifying any recommended salary adjustment and/or annual cash incentive award.
    The Compensation Committee also evaluates the performance of our NEOs and performs an assessment of market compensation for the NEOs and the general market conditions as related to compensation policy and practices in the industry and among our competitors. This information is used by the Compensation Committee to review our current pay programs and levels and to address questions related to effective compensation plans and associate retention.
    Setting Executive Compensation
    Based on the strategy and philosophy and the objectives described above, the Compensation Committee has structured our annual and long-term executive compensation programs to motivate and reward executive officers in the achievement of our business goals.
    As a part of the compensation decision making process, the Compensation Committee compares each element comprising total compensation for our NEO positions against similar positions in a peer group of other REITs (the “Compensation Peer Group”). The Compensation Committee used the SEC filings of the Compensation Peer Group to assist it in considering compensation for our NEOs. Among other items, the SEC filings provide company specific, sector specific and position specific compensation information including base salary, total annual cash compensation and long-term compensation. The Compensation Committee relied on this data to provide it with relevant market compensation data for our NEOs compared to the Compensation Peer Group in order to make compensation decisions for our NEOs. The Compensation Peer Group, which was analyzed and updated in 2025 by the Compensation Committee, consists of companies with whom we believe we compete for talent, investment opportunities, and shareholder investment dollars.
    In determining the appropriate Compensation Peer Group for 2025, the Compensation Committee utilized its compensation consultant to conduct a comprehensive analysis of the public market to identify peer companies. As part of that review, we used the following criteria:
     
      •  
    Public real estate companies structured as equity REITs that own, invest, manage and develop real estate assets similar to us through an integrated and self-managed operating platform;
     
      •  
    Companies listed and headquartered in the United States;
     
      •  
    Companies in a similar industry (Retail REITs, Office REITs, Diversified REITs, Healthcare REITs, and Residential REITs);
     
      •  
    Geographic proximity; and
     
      •  
    Companies with similar financial metrics. Specifically, we looked for companies with financial metrics that were within a range of 50% to three times our market capitalization, total assets, annual revenue and EBITDA.
     
    19

    Table of Contents
    Additionally
    , we analyzed the Institutional Shareholder Services selected peer group and the SNL US Shopping Center Index to further identify any potential REITs that could be similar in financial size, retail sector and performance.
    We compete with many companies for experienced executives, and the Compensation Committee generally benchmarked compensation for the NEOs against the compensation paid to similarly situated executives of the companies in the Compensation Peer Group. Variations may be expected based on relative experience levels, market factors, and circumstances particular to us.

    The Compensation Committee will continue to review a variety of information, including that provided by compensation consultants, as necessary, in the future to determine the appropriate level and mix of incentive compensation including benchmarking total NEO compensation to the peer group. See “
    2025 Pay for Performance Decisions.
    ”
    Compensation Related Risk Management
    Our incentive compensation programs are largely tied to objectively determinable financial and operating results and by the behavior and decisions of management. As a part of compensation administration, the Compensation Committee must take an oversight role to monitor the actions of management to ensure that the incentive programs are not creating an environment of excessive risk taking which could be detrimental to shareholders. This “risk management” aspect of the Compensation Committee’s responsibility is an evolving duty and focus. The Compensation Committee has reviewed the elements of compensation to determine whether they encourage excessive risk taking and concluded that any risks arising from our compensation policies and practices for its employees are not reasonably likely to have a material adverse effect on us. The Compensation Committee has also taken certain steps to establish policies and procedures, including limits on expenditures and a robust Board-level Investment Committee approval process, which we believe are likely to limit and manage the risk of management actions as well as measure and monitor business activities that can indicate risk and risk management needs. The combined experience of our NEOs, the length of time they have worked together, and our relatively small size at this time makes these risk management policies easier to manage. However, as we grow, the Compensation Committee will consider and adopt policies as needed to continue to ensure that decisions associated with incentive compensation opportunity do not exceed our intended risk level.
    Employment and Change in Control Agreements
    See the section titled “Employment Agreements and Payments Upon Change in Control” for a description of our Employment and Change in Control Agreements for our NEOs.
    Perquisites and Other Personal Benefits
    We provide our NEOs with benefits and other personal perquisites that we deem reasonable and consistent with our overall compensation program. Such benefits enable us to attract and retain superior employees for key positions. The Compensation Committee periodically reviews our overall compensation program and specific perquisites provided to the NEOs.
    Chief Executive Officer Compensation and Employee Compensation and Pay Ratio
    Pursuant to Section 953(b) of the Dodd-Frank Act and in accordance with Item 402(u) of Regulation
    S-K,
    we have estimated the ratio between the total annual compensation of our CEO and the median of the annual total compensation of all employees (excluding the CEO). We identified the representative “median employee” based on the taxable compensation of all full-time, part-time and temporary employees employed by us on December 31, 2025, then we calculated the median employee’s compensation using the same methodology we use for our NEOs as set forth in the “Total” column in the Summary Compensation Table below. This is the same methodology we used for the 2024 pay ratio. We believe the CEO pay ratio information set forth below constitutes a reasonable estimate, calculated in a manner consistent with the applicable SEC rules and applicable guidance.
     
    22

    Table of Contents
    For the fiscal year ended December 31, 2025, Mr. Holeman, our CEO, had annual total compensation of $2,087,555 and our median employee had annual total compensation of $93,757. Therefore, we estimate that the ratio between the annual total compensation of our CEO to the annual total compensation of our median employee is approximately 22 to 1.
    Compensation Committee Interlocks and Insider Participation
    The Compensation Committee is currently composed of Ms. Feng and Messrs. Jones and Miller, with Ms. Feng serving as chair. None of the members of the Compensation Committee during 2025 or previously served as an officer or employee for us and none of our executive officers has served on the board of directors or compensation committee of any company whose executive officers served on the Compensation Committee or our Board.
    Compensation Consultant
    To support the Compensation Committee in fulfilling its duties, the Compensation Committee directly retained an external compensation consultant to assist with its design and evaluation of compensation for our executive officers and trustees. Pursuant to its charter, the Compensation Committee shall retain, as deemed necessary or appropriate by the Compensation Committee, any compensation consultant, independent legal counsel or other compensation advisor and shall approve the advisor’s fees and other retention terms.
    In January 2025, the Compensation Committee retained Zayla Partners (“Zayla”) to provide executive officer and trustee compensation consulting services. During fiscal year 2025, Zayla did not provide any additional services to us or our affiliates.
    Based upon and following receipt of the advice of Zayla, the Compensation Committee reviewed and approved our goals and objectives relevant to CEO and executive compensation and the compensation payable to our CEO and other executive officers for fiscal year 2025.
    As required by its charter and by the NYSE listing standards, the Compensation Committee performed an independence assessment of Zayla and determined that Zayla should be considered independent based on the following factors:
     
      •  
    Zayla has not provided and will not provide any other services to us other than compensation consulting services.
     
      •  
    The fees paid to Zayla by us were less than 1% of Zayla’s total revenue for the year.
     
      •  
    Zayla has developed and provided to us their Conflict of Interest Policy.
     
      •  
    There are no business or personal relationships between Zayla and any member of the Compensation Committee or any of our executive officers.
    Accordingly, the Compensation Committee determined that the services provided by Zayla to the Compensation Committee did not give rise to any conflicts of interest.

    Employment Agreements and Payments Upon Change in Control
    Employment Agreements.
    On March 14, 2025, the Company entered into a Severance and Change in Control Agreement dated as of March 14, 2025 (the “Agreements”) with each of David K. Holeman, Chief Executive Officer; Christine J. Mastandrea, President and Chief Operating Officer, J. Scott Hogan, Chief Financial Officer;; Peter A. Tropoli, General Counsel and Corporate Secretary; and Soklin “Michelle” Siv, Senior Vice President of Human Resources (collectively, the “Executives”). For Mr. Holeman, the Agreement replaces the prior Employment Agreement dated August 29, 2014 and the Amendments to Employment Agreements dated May 23, 2022 and February 10, 2021 (collectively, the “Previous Holeman Employment Agreements”), that Mr. Holeman previously entered into with the Company. For Ms. Mastandrea, the Agreement replaces the prior Change in Control Agreement dated August 29, 2014, and the Amendments to Change in Control Agreement dated May 23, 2022 and February 10, 2021 (collectively, the “Previous Mastandrea Employment Agreement”) that Ms. Mastandrea previously entered into with the Company. For Messrs. Hogan and Tropoli and Ms. Siv the Agreements replace the prior Severance and Change in Control Agreements dated May 23, 2022.
    The Agreements have a three year term and automatically renew for successive additional three-year terms unless either party gives written notice of
    non-renewal
    at least ninety (90) days before the end of the current term. However, if a Change in Control has occurred during any term, the term of the Agreement shall end no earlier than twenty four (24) calendar months after the end of the calendar month in which the Change in Control occurs.
    The severance benefits that the Executives may receive if their employment terminates under certain conditions differ depending on whether a termination occurs (a) within a
    two-year
    period following a Change in Control (as defined in the Agreement, with the
    two-year
    period following a Change in Control being referred to as the “Change in Control Period”), or (b) in the absence of a Change in Control or outside the Change in Control Period, in each case as described below.
    If an Executive is terminated without “Cause” (as defined in the Agreement to mean termination for (i) failing to devote the time and effort required to perform the Executive’s duties, (ii) being convicted of a felony involving moral turpitude, (iii) engaging in acts in violation of confidentiality provisions of the Agreement, or willfully, wantonly and without approval of the Board taking any action that the Executive knows to be materially adverse to the interest of the Company and its shareholders) or the Executive terminates his or her employment for “Good Reason” (also as defined in the Agreement to mean (i) the Executive’s base salary, annual bonus payment, or benefits are reduced by 10% or more, (ii) the Company fails to provide equity award granted pursuant to award agreements, (iii) the Executive’s duties with the Company are reduced to such an extent that a material reduction of the Executive’s authority results, or (iv) the Executive’s principal place of employment for the company is material relocated and the Executive is required to relocate), in either case absent a Change in Control or outside the Change in Control Period, then the Executive will receive a cash lump sum payment equal to the sum of (i) eighteen (18) months for Mr. Holeman and Ms. Mastandrea, and twelve (12) months for Messrs. Hogan, Tropoli and Ms. Siv (the “Other Executives”), respectively, of base salary, (ii) 150% (for Mr. Holeman and Ms. Mastandrea) and 100% (for the Other Executives), respectively, of the Executive’s average annual cash bonus, if any, paid with respect to the three full calendar years prior to termination of employment, (iii) immediate vesting of shares granted pursuant to the Company’s 2018 Long Term Equity Incentive Ownership Plan (the “Equity Incentive Plan”) at the higher of target vesting or performance vesting, and (iv) the replacement cost of eighteen (18) months (for Mr. Holeman and Ms. Mastandrea) and twelve (12) months (for the Other Executives), respectively, of medical benefits, calculated as if such Executives elected COBRA continuation coverage.
    If, during the Change in Control Period, an Executive is terminated without Cause or the Executive terminates his or her employment for Good Reason, then the Executive will receive a cash lump sum payment equal to the sum of (i) thirty (30) months (for Mr. Holeman and Ms. Mastandrea) and eighteen (18) months (for the other Executives), respectively, of base salary, (ii) 250% of average annual cash bonus (for Mr. Holeman and Ms. Mastandrea) and 150% of the average annual cash bonus (for the Other Executives), if any, paid with respect to the three full calendar years prior to termination of employment, (iii) immediate vesting
     
    34

    Table of Contents
    of shares granted pursuant to the Equity Incentive Plan at the higher of target vesting or performance vesting, (iv) the replacement cost of (i) thirty (30) months (for Mr. Holeman and Ms. Mastandrea) and eighteen (18) months (for the Other Executives), respectively, of medical benefits, calculated as if such Executive elected COBRA continuation coverage, and (v) a
    pro-rated
    portion of the Executive’s target annual bonus applicable to the year in which such termination occurred. If such severance payments, or any other payments made to an Executive in connection with a Change in Control, would be subject to the excise tax on “excess parachute payments” imposed by Section 4999 of the Internal Revenue Code, then the applicable Executive will either pay the excise tax or have his or her payments capped at a level so there would be no excise tax depending upon which option provides the Executive with the greatest benefit on an
    after-tax
    basis.
    For Mr. Holeman the May 23, 2022 agreement provided for a retention payment, due on March 15, 2025 for employment through December 31, 2024 in the amount of $375,000, or in the event employment is terminated by the Company without Cause, by Employee for Good Reason, or due to Employee’s death or becoming Disabled prior to December 31, 2024. For Ms. Mastandrea, the May 23, 2022 agreement provides for a retention payment due on March 15, 2025 for employment through December 31, 2024 in the amount of $240,000 or in the event of employment is terminated by the Company without Cause, by Employee for Good Reason, or due to Employee’s death or becoming Disabled prior to December 31, 2024. These retention amounts were approved on February 4, 2021 and included in the Previous Holeman Employment Agreement and in the Previous Mastandrea Employment Agreement. The retention payments for Mr. Holeman and Ms. Mastandrea were paid in March 2025.
    Pursuant to the Agreements, an Executive’s receipt of any severance benefits is expressly conditioned on the Executive executing, and not revoking, a release of claims against the Company. The Agreements also include a confidentiality covenant and a covenant prohibiting the Executive from soliciting employees and customers to leave the Company for one year after termination of employment.
    Treatment of Equity Upon Change in Control.
    In the event of shareholder approval of the First Amendment to the 2018 Plan and the participant’s death or disability any unvested restricted common shares or units will immediately vest. In the event of a Change in Control of the Company, as defined below and a Termination without cause or for good reason, as defined below, (i) all restricted shares, restricted share units, and options theretofore granted and not yet vested, will become fully vested (and restricted share units shall be automatically replaced with fully vested shares), exercisable and issued as of a time immediately before the Change in Control, and (ii) all restrictions and conditions applicable to restricted shares and other share awards will be deemed to have been satisfied as of the date of the Change in Control.
    For purposes of our Amended Plan, “Change in Control” means, unless otherwise defined in the applicable award agreement, any of the following events:
     
      •  
    any person or entity, including a “group” as defined in Section 13(d)(3) of the Exchange Act, other than us or one of our wholly-owned subsidiaries or any employee benefit plan of us or any of our subsidiaries, becomes the beneficial owner of 35% or more of the combined voting power of our outstanding securities that may be cast for the election of our trustees;
     
      •  
    as the result of, or in connection with, any cash tender or exchange offer, merger or other business combination or contested election, less than a majority of the voting power of our outstanding securities or any successor company or entity entitled to vote generally in the election of our trustees or other corporation or entity after such transaction is held in the aggregate by our security holders entitled to vote generally in the election of our trustees immediately prior to such transaction;
     
      •  
    during any period of two consecutive years, individuals who at the beginning of that period constitute our Board cease for any reason to constitute at least a majority thereof, unless the election, or the nomination for election by our shareholders, of each of our trustees first elected during that period was approved by a vote of at least
    two-thirds
    of our trustees then still in office who were (a) our trustees at the beginning of that period, and (b) not initially (1) appointed or elected to office as a result of either an actual or threatened election and/or proxy contest by or on behalf of a person other than our Board, or (2) designated by a person who has entered into an agreement with us to effect a transaction described in the first two bullet points above or the following two bullet points below;

    Trustee Compensation
    We use a combination of cash and share-based compensation to attract and retain qualified candidates to serve on the Board. In setting Board compensation, the Board considers the significant amount of time trustees expend in fulfilling their duties as well as the skill level it requires of members of the Board.
    Non-employee
    trustees are compensated for their service on our Board as shown below. David K. Holeman, our Chief Executive Officer and only
    non-employee
    trustee, receives no additional compensation for serving as a trustee.

      •  
    Annual retainer fee of $55,000

    Funds From Operations (

    ) (
    “
    FFO
    ”
    )
    The National Association of Real Estate Investment Trusts (“NAREIT”) defines FFO as net income (loss) available to common shareholders computed in accordance with GAAP, excluding depreciation and amortization related to real estate, gains or losses from the sale of certain real estate assets, gains and losses from change in control, and impairment write-downs of certain real estate assets and investments in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity. We calculate FFO in a manner consistent with the NAREIT definition and also include adjustments for our unconsolidated real estate partnership.
    Core Funds from Operations (“Core FFO”) is a
    non-GAAP
    measure. From time to time, we report or provide guidance with respect to “Core FFO” which removes the impact of certain
    non-recurring
    and
    non-operating
    transactions or other items we do not consider to be representative of our core operating results including, without limitation, default interest on debt of real estate partnership, extinguishment of debt cost, gains or losses associated with litigation involving the Company that is not in the normal course of business, and proxy contest professional fees.
    Management uses FFO and Core FFO as a supplemental measure to conduct and
    evaluate
    our business because there are certain limitations associated with using GAAP net income (loss) alone as the primary measure of our operating performance.
    Historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate assets diminishes predictably over time. Because real estate values instead have historically risen or fallen with market conditions, management believes that the presentation of operating results for real estate companies that use historical cost accounting is insufficient by itself. In addition, securities analysts, investors and other interested parties use FFO and Core FFO as the primary metric for comparing the relative performance of equity REITs.
    FFO and Core FFO should not be considered as an alternative to net income or other measurements under GAAP, as an indicator of our operating performance or to cash flows from operating, investing or financing activities as a measure of liquidity. FFO does not reflect working capital changes, cash expenditures for capital improvements or principal payments on indebtedness. Although our calculation of FFO is consistent with that of NAREIT, there can be no assurance that FFO and Core FFO presented by us is comparable to similarly titled measures of other REITs.

    NOI: Net Operating
    Income
    :
    Management believes that NOI is a useful measure of our property operating performance. We define NOI as operating revenues (rental and other revenues) less property and related expenses (property operation and maintenance and real estate taxes). Other REITs may use different methodologies for calculating NOI and, accordingly, our NOI may not be comparable to other REITs. Because NOI adjusts for general and administrative expenses, depreciation and amortization, equity in earnings of real estate partnership, interest expense, interest, dividend and other investment income, provision for income taxes, gain or loss on sale of property from discontinued operations, management fee, net of related expenses, gain or loss on sale or disposal of assets, gain on loan forgiveness, our pro rata share of NOI of equity method investments and net income attributable to noncontrolling interests, it provides a performance measure that, when compared year-over-year, reflects the revenues and expenses directly associated with owning and operating commercial real estate properties and the impact to operations from trends in occupancy rates, rental rates and operating costs, providing perspective not immediately apparent from net income. We use NOI to evaluate our operating performance since NOI allows us to evaluate the impact that factors such as occupancy levels, lease structure, lease rates and tenant base have on our results, margins and returns. In addition, management believes that NOI provides useful information to the investment community about our property and operating performance when compared to other REITs since NOI is generally recognized as a standard measure of property performance in the real estate industry. However, NOI should not be viewed as a measure of our overall financial performance since it does not reflect general and administrative expenses, depreciation and amortization, interest expense, interest income, provision for income taxes and gain or loss on sale or disposition of assets, the level of capital expenditures and leasing costs necessary to maintain the operating performance of our properties.
    Same
    Store NOI:
    Management believes that Same Store NOI is a useful measure of our property operating performance because it includes only the properties that have been owned for the entire period being compared, and that it is frequently used by the investment community. Same Store NOI assists in eliminating differences in NOI due to the acquisition or disposition of properties during the period being presented, providing a more consistent measure of our performance. We define Same Store NOI as operating revenues (rental and other revenues, excluding straight-line rent adjustments, amortization of above/below market rents, and lease termination fees) less property and related expenses (property operation and maintenance and real estate taxes),
    Non-Same
    Store NOI, and NOI of our investment in Pillarstone OP (pro rata). We define
    “Non-Same
    Stores” as properties that have been acquired since the beginning of the period being compared and properties that have been sold, but not classified as discontinued operations. Other REITs may use different methodologies for calculating Same Store NOI, and accordingly, our Same Store NOI may not be comparable to that of other REITs.

    EBITDAre: The

    Association of Real Estate
    Investment
    Trusts (“NAREIT”) defines EBITDAre as net income computed in accordance with GAAP, plus interest expense, income tax expense, depreciation and amortization and impairment write-downs of depreciable property and of investments in unconsolidated affiliates caused by a decrease in value of depreciable property in the affiliate, plus or minus losses and gains on the disposition of depreciable property, including losses/gains on change in control and adjustments to reflect the entity’s share of EBITDAre of the unconsolidated affiliates and consolidated affiliates with
    non-controlling
    interests. We calculate EBITDAre in a manner consistent with the NAREIT definition. Management believes that EBITDAre represents a supplemental
    non-GAAP
    performance measure that provides investors with a relevant basis for comparing REITs. There can be no assurance the EBITDAre as presented by us is comparable to similarly titled measures of other REITs. EBITDAre should not be considered as alternatives to net income or other measurements under GAAP as indicators of operating performance or to cash flows from operating, investing or financing activities as measures of liquidity. EBITDAre does not reflect working capital changes, cash expenditures for capital improvements or principal payments on indebtedness.
    Net debt: We present net debt, which we define as total debt net of insurance financing less cash plus our proportional share of net debt of real estate partnership, and net debt to pro forma EBITDAre, which we define as net debt divided by EBITDAre because we believe they are helpful as supplemental measures in assessing our ability to service our financing obligations and in evaluating balance sheet leverage against that of other REITs. However, net debt and net debt to pro forma EBITDAre should not be viewed as a stand-alone measure of our overall liquidity and leverage. In addition, our REITs may use different methodologies for calculating net debt and net debt to pro forma EBITDAre, and accordingly our net debt and net debt to pro forma EBITDAre may not be comparable to that of other REITs.

    Certain Relationships and Related Transactions, and Director Independence

    Policies and Procedures for Transactions with Related Persons

    Under SEC rules, a related person transaction is any transaction or any currently proposed transaction in which we were or are to be a participant, the amount involved exceeds $120,000, and in which any related person had or will have a direct or indirect material interest. A “related person” is a director, officer, nominee for director or a more than 5% shareholder since the beginning of our last completed fiscal year, and their immediate family members.

    Pursuant to its charter, the Nominating and Corporate Governance Committee is responsible for conducting a reasonable prior review of any related party transactions for any potential or actual conflicts of interest.

    Under our Declaration of Trust, we may enter into any contract or transaction with our trustees, officers, employees or agents (or any affiliated person), provided that in the case of any contract or transaction in which any of our trustees, officers, employees or agents (or any affiliated person) have a material financial interest, (1) the fact of the interest is disclosed or known to the following: (a) the Board, and the Board shall approve or ratify the contract or transaction by the affirmative vote of a majority of disinterested trustees, even if the disinterested trustees constitute less than a quorum, or (b) the shareholders entitled to vote, and the contract or transaction is authorized, approved or ratified by a majority of the votes cast by the shareholders entitled to vote other than the votes of shares owned of record or beneficially by the interested party; or (2) the contract or transaction is fair and reasonable to us. In addition, the Nominating and Corporate Governance Committee manages risks associated with the independence of the Board and potential conflicts of interest.

    Related Person Transactions

    The Company did not have any related person transactions in the year ended December 31, 2025.

    Director Independence

    Independence

    Under the listing standards of the NYSE, and pursuant to our Corporate Governance Guidelines and policies, we are required to have a majority of “independent” trustees and a Nominating and Corporate Governance Committee, Compensation Committee, and Audit Committee, each composed solely of independent trustees. In determining trustee independence, the Board broadly considers all relevant facts and circumstances, including the rules of the NYSE. The Board considers these issues not merely from the standpoint of a trustee, but also from that of persons or organizations with which the trustee has an affiliation. An independent trustee is free of any relationship with us or our management that may impair the trustee’s ability to make independent judgments.

    Our Board has affirmatively determined that five of our six trustee nominees are “independent” as that term is defined by the NYSE listing standards and applicable SEC rules. These trustees are Julia B. Buthman, Amy S. Feng, Kristian M. Gathright, Jeffrey A. Jones, and Donald A. Miller. As our Chief Executive Officer, David K. Holeman is not considered independent. Each of the Nominating and Corporate Governance Committee, Compensation Committee, and Audit Committee are composed solely of independent trustees.

    Principal Accountant Fees and Services

    Independent Registered Public Accounting Firm Fees and Services

    Withum Smith+Brown, P.C. (“Withum,”) has served as independent auditor for the Company since July 2025. On July 21, 2025, Whitestone REIT (the “Company”) was notified that Pannell Kerr Forster of Texas, P.C. (“PKF”), the Company’s prior independent registered public accounting firm, entered into a transaction with Withum pursuant to which certain of the professional staff and partners of PKF joined Withum due to the acquisition of certain assets of PKF by Withum. On July 21, 2025, PKF resigned as the auditors of the Company, and with the approval of the Audit Committee of the Company’s Board of Directors, Withum was engaged as the Company’s independent registered public accounting firm.

    The following table sets forth the aggregated fees and costs billed by PKF and Withum to the Company for the years ended December 31, 2025 and 2024 are identified below. 100% of the fees described below were approved by the Audit Committee.
