**Pillarstone Capital REIT**

**Notes to Consolidated Financial Statements**

**(unaudited)**

**1.** **Organization and Summary of Significant Accounting Policies**

Pillarstone Capital REIT (the "Company," "Pillarstone," "we," "our," or "us") is a Maryland real estate investment trust ("REIT") engaged in investing in, owning and operating commercial properties. We own 18.6% of Pillarstone Capital REIT Operating Partnership LP ("Pillarstone OP") and serve as its general partner. Substantially all of our operations and activities are conducted for the benefit of and through Pillarstone OP. As the general partner of Pillarstone OP, we had the exclusive power to manage and conduct the business of Pillarstone OP, subject to certain customary exceptions.

Pillarstone OP owned two office buildings in the Dallas metropolitan area and six office/warehouse and retail locations in the Houston metropolitan area having approximately 927 thousand square feet of gross leasable area. Following the period covered by this report, we sold all of our Real Estate Assets pursuant to the plans of liquidation as part of bankruptcy filings made by Pillarstone and each of the entities we controlled (see Note 14).

*Liquidity and Financial Resources.* On December 8, 2016, we and Pillarstone OP, entered into a Contribution Agreement (the "Contribution Agreement") with Whitestone REIT Operating Partnership, L.P. ("Whitestone OP"), a subsidiary and the operating partnership of Whitestone REIT, both of which were related parties to Pillarstone and Pillarstone OP. Pursuant to the terms of the Contribution Agreement, Whitestone OP contributed to Pillarstone OP all of the equity interests in four of its wholly-owned subsidiaries (the "Subsidiaries"): Whitestone CP Woodland Ph. 2, LLC, a Delaware limited liability company; Whitestone Industrial-Office, LLC, a Texas limited liability company; Whitestone Offices, LLC, a Texas limited liability company; and Whitestone Uptown Tower, LLC, a Delaware limited liability company ("Uptown Tower") that owned 14 real estate assets (the "Real Estate Assets" and, together with the Subsidiaries (the "Property"), for aggregate consideration of approximately $84 million, consisting of (1) approximately $18.1 million of Class A units representing limited partnership interests in Pillarstone OP ("OP Units"), issued at a price of $1.331 per OP Unit; and (2) the assumption of approximately $65.9 million of liabilities by Pillarstone OP. Pursuant to the Contribution Agreement, Pillarstone became the general partner of Pillarstone OP with an equity ownership interest in Pillarstone OP totaling approximately 18.6% valued at $4.1 million as of the date of the Contribution Agreement.

Pursuant to the Contribution Agreement, Pillarstone agreed to file with the SEC on or prior to June 8, 2018, a shelf registration statement to register for sale under the Securities Act of 1933, as amended, the issuance of the common shares in the Company that may be issued upon redemption of the OP Units issued pursuant to the Contribution Agreement and the offer and resale of such common shares by the holders thereof. In addition, pursuant to the Contribution Agreement, in the event of a Change of Control (as defined therein), Pillarstone OP shall have the right, but not the obligation, to repurchase the OP Units issued thereunder from Whitestone OP at their initial issue price of $1.331 per OP Unit. Pillarstone and Whitestone agreed to extend the filing of the shelf registration statement to the date that the Company closes a public equity offering.

In connection with the Contribution Agreement, (1) with respect to each Real Estate Asset (other than the Real Property Asset owned by Uptown Tower), Whitestone TRS, Inc. ("Whitestone TRS"), a subsidiary of Whitestone, entered into a Management Agreement with Pillarstone OP who owns such Real Estate Asset and (2) with respect to Uptown Tower, Whitestone TRS entered into a Management Agreement with Pillarstone OP (collectively, the "Management Agreements"). Pursuant to the Management Agreements with respect to each Real Estate Asset (other than Uptown Tower), Whitestone TRS agreed to provide certain property management, leasing and day-to-day advisory and administrative services to such Real Estate Asset in exchange for (x) a monthly property management fee equal to 5.0% of the monthly revenues of such Real Estate Asset and (y) a monthly asset management fee equal to 0.125% of gross asset value ("GAV") (as defined in each Management Agreement as, generally, the purchase price of the respective Real Estate Asset based upon the purchase price allocations determined pursuant to the Contribution Agreement, excluding all indebtedness, liabilities or claims of any nature) of such Real Estate Asset. Pursuant to the Management Agreement with respect to Uptown Tower, Whitestone TRS agreed to provide certain property management, leasing and day-to-day advisory and administrative services to Pillarstone OP in exchange for (x) a monthly property management fee equal to 3.0% of the monthly revenues of Uptown Tower and (y) a monthly asset management fee equal to 0.125% of GAV of Uptown Tower. These activities were conducted by Whitestone TRS and Whitestone REIT using their own employees, processes, and systems and in some cases, third-party providers for services they sub-contracted to perform.

As a result of the Contribution Agreement, Whitestone OP owned approximately 81.4% and Pillarstone owned approximately 18.6% of the outstanding equity in Pillarstone OP, which is fully consolidated in Pillarstone's financial statements.

On July 19, 2022, we received written notice that Whitestone TRS confirmed termination of the Management Agreements for the Real Estate Assets. We had previously communicated to Whitestone REIT our plan to internalize the management of our Real Estate Assets, but we had not made efforts to terminate the Management Agreements or transition the management activities. However, Whitestone REIT stated in its notice letter that while it had not received written notice of the termination of the Management Agreements, it "confirms receipt of your intent to terminate, and hereby confirms termination of the Agreements effective 30 days from" July 19, 2022.

------

Prior to receiving the termination notice, we had anticipated an orderly transition of the management of the Real Estate Assets over an appropriate timeframe, particularly as Whitestone OP owned 81.4% of Pillarstone OP as a limited partner. As a result, we were materially and adversely affected by Whitestone's abrupt termination of the Management Agreements, incomplete and inadequate delivery of books and records, our website and other materials required to be delivered under the Management Agreements, and the failure to provide for an appropriate transition. We had no way to continue our accounting and financial reporting responsibilities as a public company. Further, for several months following the abrupt termination of services by Whitestone, we were unable to systematically invoice our tenants and pursue collection of delinquent accounts.

Within days after the termination of the Management Agreements by Whitestone, we internalized management and began to manage the Real Estate Assets and our business without an external management company. This process involved commencing a selection process for an enterprise resource planning, or ERP, system of our own. We immediately hired an experienced management team with prior experience working with our property portfolio, including former Whitestone senior staff. Our newly assembled leadership team quickly engaged consultants (a) to assist us in implementing the newly selected ERP system, (b) to analyze, reconcile and transform historical data obtained from Whitestone REIT into a usable format for our new system and (c) to design procedures for regular accounting closes and preparation of accurate and reliable financial statements for our shareholders and other stakeholders.

In 2023, we continued our work to restore operations that were disrupted by Whitestone's abrupt termination as manager of our Real Estate Assets. In that time, we were working to extend the maturity date or to find new financing for mortgage indebtedness secured by our Uptown Tower office building or a buyer for the Uptown Tower property. The borrower, Whitestone Uptown Tower, LLC, Pillarstone OP's subsidiary that owned the Uptown Tower office building, was not in compliance with loan covenants. These efforts were unsuccessful and soon after the mortgage's maturity on October 1, 2023, the lender delivered a notice of foreclosure sale to the borrower.

On December 1, 2023, Whitestone Uptown Tower, LLC filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Northern District of Texas in the case styled *In re: Whitestone Uptown Tower, LLC a/a/ Pillarstone Capital REIT Operating Partnership*, Case No. 23-32832-mvl-11, in the United States Bankruptcy Court for the Northern District of Texas, Dallas Division.

On March 4, 2024, bankruptcy cases were filed for us and Pillarstone OP, as well as Whitestone CP Woodland Ph. 2, LLC, Whitestone Industrial-Office, LLC and Whitestone Offices, LLC, the subsidiaries owning our Real Estate Assets other than Uptown Tower, which were consolidated into the jointly administered bankruptcy cases styled In re: Whitestone Industrial-Office, LLC, et. al., Case No. 24-30653-mvl-11, in the United States Bankruptcy Court for the Northern District of Texas, Dallas Division, the same court as, but separate cases from, the Whitestone Uptown Tower, LLC bankruptcy case.

Following the period covered by this report, we sold all of our Real Estate Assets pursuant to the plan of liquidation in the jointly administered bankruptcy cases and the Whitestone Uptown Tower plan of reorganization (see Note 14).

*Going Concern.* The accompanying consolidated financial statements have been prepared assuming that we will continue as a going concern. In addition to the events described above, we have incurred significant losses since the year ended December 31, 2020 and have an accumulated deficit of approximately $23.7 million as of June 30, 2023 and need to raise substantial amounts of additional funds to meet our obligations and afford us time to implement our business plan and resume profitable operations. These conditions raise substantial doubt about the Company's ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Until the sales of our Real Estate Assets in 2024 and 2025, we were dependent on cash generated by our ownership of the eight Real Estate Assets to meet our liquidity needs. Our debts have been repaid from the proceeds from the sales of our Real Estate Assets except for those of certain unsecured creditors subject to the Chapter 11 bankruptcy filings. We expect that remaining third-party indebtedness will be repaid in due course from these same proceeds once payment is approved by the Court.

To implement our business strategy, additional capital will need to be raised. Our ability to access the capital markets will be dependent on a number of factors, including general market conditions and market perceptions about our Company. There can be no assurance that we will be able to raise capital, obtain debt financing, or improve operating results sufficiently to continue as a going concern, if at all. The consolidated financial statements included in this report do not include any adjustments that might result from the outcome of this uncertainty.

*Basis of presentation*. The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles ("U.S. GAAP") and applicable rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. These consolidated financial statements present the Company's consolidated financial condition and results of operations including those of Pillarstone OP which we control as general partner. Noncontrolling interest in the accompanying consolidated financial statements represents the share of equity and earnings of Pillarstone OP allocable to holders of partnership interests other than us. All significant intercompany balances and transactions have been eliminated in consolidation.

------

The unaudited consolidated balance sheet as of December 31, 2022 included herein was derived from the audited consolidated financial statements as of that date, but does not include all disclosures, including certain notes required by GAAP on an annual reporting basis. In management's opinion, the unaudited consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the balance sheets and statements of operations, comprehensive income, stockholders' equity, and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year or any future period.

These unaudited consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes included in its Annual Report on Form 10-K for the year ended December 31, 2022.

*Use of estimates.* The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include the estimated fair value of properties acquired, allowance for doubtful accounts, impairment, the estimated useful lives for depreciable and amortizable assets and costs, and deferred taxes and the related valuation allowance for deferred taxes.

*Recent accounting pronouncements*. In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-07, *Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures* ("ASU 2023-07"). The amendments in ASU 2023-07 require incremental disclosures related to a public entity's reportable segments and increase the frequency with which most segment disclosures are made. Incremental disclosures required by the ASU include significant segment expenses regularly provided to the chief operating decision maker ("CODM") and included within the segment's measure of profit or loss, the title and position of the CODM and an explanation how the CODM uses the reported measure of a segment's profit or loss to assess performance and allocate resources, and the amount and composition of other segment items necessary to reconcile segment revenue, significant expenses, and the reported measure of profit or loss. The ASU also expands interim disclosure requirements such that nearly all annual quantitative segment disclosures will be made on an interim basis. Lastly, ASU 2023-07 requires that entities with a single reportable segment provide all segment disclosures that are not evident from the primary financial statements, including significant segment expenses, consistent with the approach used by management to evaluate performance, which affects the Company's disclosures. ASU 2023-07 is effective and will be adopted starting with the Company's 2024 annual report, and on a quarterly basis thereafter, and requires retrospective application.

In December 2023, the FASB issued ASU 2023-09, *Income Taxes (Topic 740): Improvements to Income Tax Disclosures* ("ASU 2023-09"). The amendments in ASU 2023-09 require reporting entities to disclose annual income taxes paid, net of refunds, disaggregated by federal, state, and foreign taxes and to provide additional disaggregated information for individual jurisdictions that equal or exceed 5% of total income taxes paid, net of refunds. ASU 2023-09 also requires public business entities to disclose additional categories of information about federal, state, and foreign income taxes in their annual rate reconciliation table and provide more information about some categories if the quantitative threshold is met. The ASU will also require disclosure of amounts and percentages in the annual rate reconciliation table, rather than amounts or percentages, and will eliminate certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. ASU 2023-09 is effective starting with the Company's 2025 annual consolidated financial statements and may be applied prospectively to only the income tax disclosures provided for 2025 or retrospectively by providing revised disclosures for all periods presented. Early adoption is permitted. The Company is currently evaluating the impact of the ASU; however, incremental disclosures will likely be provided on a prospective basis in the Company's 2025 annual consolidated financial statements upon adoption.

In November 2024, the FASB issued ASU 2024-03, *Income Statement* – *Reporting Comprehensive Income* – *Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses* ("ASU 2024-03"). The amendments in ASU 2024-03 require public business entities to disclose in the notes to the financial statements, among other things, specific information about certain costs and expenses including purchases of inventory, employee compensation, and depreciation, amortization, and depletion expenses for each caption on the income statement where such expenses are included. ASU 2024-03 is effective starting with the Company's 2027 annual consolidated financial statements and on a quarterly basis thereafter. Early adoption is permitted, and the amendments may be applied prospectively to reporting periods after the effective date or retrospectively to all periods presented in the financial statements. The Company is currently evaluating the extent to which its disclosures will be affected by the ASU.

**6.** **Variable Interest Entity**

Pillarstone became the general partner of Pillarstone OP with an equity ownership interest in Pillarstone OP totaling approximately 18.6% pursuant to the Contribution Agreement. Pursuant to the terms of the Contribution Agreement, Whitestone OP contributed to Pillarstone OP all of the equity interests in four of its wholly owned subsidiaries that owned 14 real estate assets at that time. In connection with the Contribution Agreement, the Company, as the general partner of Pillarstone OP, entered into an Amended and Restated Agreement of Limited Partnership. Pursuant to the Amended and Restated Agreement of Limited Partnership, subject to certain protective rights of the limited partners described below, the general partner has full, exclusive and complete responsibility and discretion in the management and control of Pillarstone OP, including the ability to cause Pillarstone OP to enter into certain major transactions including a merger of Pillarstone OP or a sale of substantially all of the assets of Pillarstone OP. The limited partners have no power to remove the general partner without the general partner's consent. In addition, pursuant to the Amended and Restated Agreement of Limited Partnership, the general partner may not conduct any business without the consent of a majority of the limited partners other than in connection with certain actions described therein. The Company is deemed to exercise significant influence over Pillarstone OP as it has the power to direct the activities that most significantly impact Pillarstone OP's economic performance and the Company's right to receive benefits based on its ownership percentage in Pillarstone OP. Accordingly, the Company accounts for Pillarstone OP as a Variable Interest Entity.

The Amended and Restated Agreement of Limited Partnership designates two classes of units of limited partnership interest in Pillarstone OP: the OP Units and LTIP units. In general, LTIP units are similar to the OP Units and will receive the same quarterly per-unit profit distributions as the OP Units. The rights, privileges, and obligations related to each series of LTIP units will be established at the time the LTIP units are issued. As profits interests, LTIP units initially will not have full parity, on a per-unit basis, with OP Units with respect to liquidating distributions. Upon the occurrence of specified events, LTIP units can over time achieve full parity with the OP Units and therefore accrete to an economic value for the holder equivalent to OP Units. If such parity is achieved, vested LTIP units may be converted on a one-for-one basis into OP Units, which in turn are redeemable by the holder for cash or, at the Company's election, exchangeable for Common Shares on a one-for-one basis.

The carrying amounts and classification of certain assets and liabilities for Pillarstone OP in our consolidated balance sheets consists of the following (in thousands):

The mortgage debt was an obligation of Whitestone Uptown Tower, LLC as borrower, collateralized by the Uptown Tower property and guaranteed by Whitestone OP. As of June 30, 2023, we were not in compliance with loan covenants. The mortgage loan matured on October 1, 2023. The registrant and the borrower had been working to extend the maturity date and to find new financing or a buyer for the Uptown Tower property. However, on October 19, 2023, Whitestone objected to a proposed sale of the Uptown Tower property under the Status Quo Order issued by the court in the previously disclosed lawsuit Whitestone OP instituted against us in the Delaware Court of Chancery.

On October 24, 2023, the lender delivered a notice of foreclosure sale to the borrower providing notice that, among other things, as of the maturity date, the borrower failed to repay all amounts due under the note, and making a demand on (1) the borrower and all persons and entities obligated on the promissory note evidencing the mortgage loan (except to the extent that the obligation is expressly limited by written contract or applicable law) for payment in full of the entire indebtedness, and on (2) the borrower for payment of rents and proceeds of any rents to which the lender is entitled under the mortgage loan documents and Texas Property Code chapter 64, Assignment of Rents to Lienholder. The notice of foreclosure sale also included a notice of foreclosure sale regarding the planned foreclosure sale of Uptown Tower on December 5, 2023.

On December 1, 2023, Whitestone Uptown Tower, LLC filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Northern District of Texas in the case styled *In re: Whitestone Uptown Tower, LLC a/a/ Pillarstone Capital REIT Operating Partnership*, Case No. 23-32832-mvl-11, in the United States Bankruptcy Court for the Northern District of Texas, Dallas Division. The filing of the petition constituted an event of default under the mortgage loan. Prior to the filing of the bankruptcy petition, in November 2023, representatives of our board of trustees attempted to initiate discussions with representatives of Whitestone REIT's board of trustees to address these matters and to approach Rialto Capital Advisors, LLC jointly. However, without the borrower's knowledge or consent, Whitestone attempted to pay off the loan and grant broad releases to the lender and special servicer on behalf of the borrower, including the application of the trapped cash, escrows and reserves to the indebtedness. No Whitestone REIT entity had the authority to make such agreements on behalf of the borrower, and we were informed that the agreement was not consummated, but Whitestone did send approximately $13.6 million to Rialto Capital Advisors, LLC pursuant to this arrangement.

In June 2024, Whitestone Uptown Tower, LLC and Whitestone OP each settled with the lender. Whitestone Uptown Tower entered into a loan agreement with American Bank, N.A. for a loan amount of up to $1,500,000, secured by Uptown Tower and all of the other assets of Whitestone Uptown Tower. Whitestone Uptown Tower paid approximately $1.1 million to the prior lender, and the prior lender retained approximately $2.2 million of trapped cash and escrows from the cash sweep and the approximately $13.6 million mistakenly sent to it by Whitestone OP in satisfaction of the prior mortgage loan.

The plan of reorganization in the Uptown Tower bankruptcy case, providing for the sale of Uptown Tower and treatment of claims, was confirmed in July 2024. We sold Uptown Tower in July 2025 for a purchase price of $20 million, or $17.3 million after deductions, closing costs and commissions and reimbursements to the seller, and paid off the American Bank, N.A. indebtedness.

**8.** **Convertible Notes Payable** 

On November 20, 2015, five trustees on our board of trustees, one of whom is no longer affiliated with the Company, loaned $198 thousand to the Company in exchange for convertible notes payable. The convertible notes payable accrue interest at 10% per annum and originally matured on November 20, 2018. The convertible notes payable can be converted by the noteholders into common shares at the rate of $1.331 per common share at any time. At maturity or when the Company chooses to call the convertible notes payable, the noteholders have the option to receive cash plus accrued interest or convert the convertible notes payable into common shares at $1.331 per common share. Accrued interest on these related convertible notes was approximately $154 thousand as of June 30, 2023 and $141 thousand as of December 31, 2022.

**9.** **Shareholders**' **Equity**

*Operating partnership units.* Substantially all of our business is conducted through Pillarstone OP, and we are the sole general partner. As of June 30, 2023, we owned an 18.6% interest in Pillarstone OP. At any time, limited partners in Pillarstone OP holding OP Units have the right to convert their OP Units for cash, or at our option, common shares of Pillarstone. As of June 30, 2023, there were 16,688,167 OP Units outstanding.

*Pillarstone equity.* We have authority to issue up to 450,000,000 shares of beneficial interest, $0.01 par value per share, of which 400,000,000 are classified as common shares of beneficial interest, $0.01 par value per share and 50,000,000 are classified as preferred shares of beneficial interest, $0.01 par value per share. Of the 50,000,000 preferred shares of beneficial interest, 1,518,000 shares are designated as Class A Cumulative Preferred Shares ("Class A Preferred Shares") and 300,000 shares are designated as Preferred Class C Convertible Preferred shares ("Class C Preferred Shares").

On December 26, 2021, the board authorized a dividend of one preferred share purchase right (a "Right") for each outstanding common share of the Company, payable on December 27, 2021. The description and terms of the Rights are set forth in a rights agreement, dated as of December 27, 2021 (as the same may be amended from time to time, the "Rights Agreement"), between the Company and American Stock Transfer & Trust Company, LLC, as rights agent (the "Rights Agent").

Each Right entitles the registered holder to purchase from the Company one one-thousandth (a "Unit") of a Series D Preferred Share, par value $0.01 per share, of the Company at a purchase price ("Purchase Price") of $7.00 per Unit, subject to adjustment. The Rights initially trade with the common shares and will generally only become exercisable on the 10th business day after a person or entity has become the owner of 5% or more of the common shares (20% or more with respect to certain passive institutional investors) or the commencement of a tender or exchange offer which would result in any person becoming an owner of 5% or more of the common shares, except in certain situations specified in the Rights Agreement (such person an "Acquiring Person"), with proper provision (i) to provide each holder of certain units of Pillarstone OP with the number of Rights as would be issued to the applicable holder as if the holder had exercised its applicable redemption rights relating to such units immediately prior to the distribution date under the Rights Agreement, and the Company had elected to satisfy the redemption rights by paying the holder in shares in accordance with Pillarstone OP's partnership agreement, and (ii) to provide each holder (other than the Company) of Class C Convertible Preferred Shares of beneficial interest, $0.01 par value per share, of the Company with the number of Rights, evidenced by Rights Certificates, as would be issued to such holder as if such holder had converted all of its Class C Preferred Shares into common shares immediately prior to the distribution date.

If any person or group of affiliated or associated persons becomes an Acquiring Person, each holder of a Right (other than Rights beneficially owned by an Acquiring Person, affiliates and associates of an Acquiring Person and certain transferees thereof, which Rights will thereupon become null and void) will thereafter have the right to receive upon exercise of a Right that number of common shares having a market value of two times the Purchase Price. If, after any person or group of affiliated or associated persons has become an Acquiring Person, the Company is acquired in a merger, consolidation or combination or 50% or more of its consolidated assets, cash flow or earning power are transferred, proper provisions will be made so that each holder of a Right (other than Rights beneficially owned by an Acquiring Person, affiliates and associates of an Acquiring Person and certain transferees thereof, which Rights will have become null and void) will thereafter have the right to receive upon the exercise of a Right that number of common shares of the person (or its parent) with whom the Company has engaged in the foregoing transaction having a market value of two times the Purchase Price. At any time after any person or group of affiliated or associated persons becomes an Acquiring Person and prior to the earlier of one of the events described in the previous paragraph or the acquisition by an Acquiring Person of 50% or more of the outstanding common shares, the Board may exchange the Rights (other than Rights owned by an Acquiring Person, affiliates and associates of an Acquiring Person and certain transferees thereof, which Rights will have become null and void), in whole or in part, for common shares at an exchange ratio of one common share per Right.

The Rights will expire on the earliest of (i) the close of business on December 27, 2024, (ii) the time at which the Rights are redeemed pursuant to the Rights Agreement, (iii) the closing of any merger or other acquisition transaction involving the Company that has been approved by the Board, at which time the Rights are terminated, (iv) the business day immediately following the Company's 2022 annual meeting of shareholders (including any adjournment thereof) if the Rights Agreement shall not have been approved, on or before such date, by the affirmative vote of the holders of a majority of the voting power present, in person or by proxy, and entitled to vote at a meeting of the Company's shareholders duly held in accordance with the Articles of Amendment and Restatement of the Declaration of Trust of the Company, the Company's bylaws and Maryland law, and (v) the time at which the Rights are exchanged pursuant to the Rights Agreement. The Rights are in all respects subject to and governed by the provisions of the Rights Agreement.

*Preferred shares*. The Company has outstanding 256,636 Class A Preferred Shares of which 95,226 Class A Preferred Shares were issued to the public. The Class A Preferred Shares bear a liquidation value of $10.00 per share. We have the right to redeem the Class A Preferred Shares.

------

Effective June 30, 2003, we issued 696,078 Class A Preferred Shares valued at approximately $2.4 million to James C. Mastandrea, our Chairman and previous Chief Executive Officer and President, and John J. Dee, our previous Chief Financial Officer and Senior Vice President, pursuant to separate restricted share agreements. Under each restricted share agreement, the restricted shares vest upon the date our gross assets exceed $50 million. None of the restricted shares have vested. While the Company's gross assets exceed $50 million, when considering its 18.6% ownership of Pillarstone OP, its effective ownership of gross assets is less than $50 million.

In conjunction with a one-time incentive exchange offer for Class A Preferred shareholders, Messrs. Mastandrea and Dee exchanged 534,668 of these restricted Class A Preferred Shares into 163,116 restricted common shares. The restrictions described above are also applicable to their common shares. The 161,410 restricted Class A Preferred Shares continuing to be held by Messrs. Mastandrea and Dee can each be converted into 0.305 restricted common shares.

Holders of the remaining 95,226 Class A Preferred Shares did not participate in the one-time exchange offer above and, as a result, these Class A Preferred Shares are convertible into 0.046 common shares, subject to certain formulas.

Effective September 29, 2006, Pillarstone filed articles supplementary to its Declaration of Trust, as amended, restated and supplemented with the State Department of Assessment and Taxation of Maryland designating 300,000 Class C Preferred Shares. The Class C Preferred Shares have voting rights equal to the number of common shares into which they are convertible. Each Class C Preferred Share is convertible into common shares by dividing the sum of $10.00 and any accrued but unpaid dividends on the Class C Preferred Shares by the conversion price of $1.00. The Class C Preferred Shares have a liquidation preference of $10.00 per share, plus any accrued but unpaid dividends, and can be redeemed by the board of trustees at any time, with notice, at the same price per share.

*Restricted Common Shares*. The following table summarizes the activity of our unvested restricted common shares:

---

| | | |
|:---|:---|:---|
|  | Unvested Restricted<br> Common Shares | Unvested Restricted<br> Common Shares |
|  |  | Weighted-Average |
|  | Number of | Grant-Date |
|  | Shares | Fair Value |
| Unvested at December 31, 2021 | 168449 | $11.44 |
| Vested |  |  |
| Unvested at December 31, 2022 | 168449 | $11.44 |
| Vested |  |  |
| Unvested at June 30, 2023 | 168449 | $11.44 |

---

In the above table, 163,116 restricted shares vest upon meeting performance goals as discussed under "Preferred Shares." Since the grant date, we have determined that meeting these performance goals is not probable, and no compensation expense has been recognized related to this grant. The grant date fair value of $1.8 million would be recognized at the point we deem it probable that we would meet the performance goals. The balance of 5,333 restricted shares had grant date fair values totaling $79 thousand, which was recognized in prior periods though the restrictions remain on the shares.

**10.** **Stock-Based Compensation**

At the 2016 Annual Meeting of Shareholders, our shareholders approved the 2016 Equity Plan ("2016 Plan"). The 2016 Plan provides that awards may be made in common shares of the Company or units in the Company's operating partnership, which may be converted into common shares. Subject to adjustment as provided by the terms of the 2016 Plan, the maximum aggregate number of common shares with respect to which awards may be granted under the 2016 Plan will be increased based on future issuances of common shares and units of the operating partnership, including issuances pursuant to the 2016 Plan, so that at any time the maximum number of shares that may be issued under the 2016 Plan shall equal 12.5% of the aggregate number of common shares and units of the operating partnership issued and outstanding (other than treasury shares and/or units issued to or held by the Company). There were 2,086,655 shares available for grant under the 2016 Plan at June 30, 2023.

The Company did not recognize any stock-based compensation expense for trustee compensation or employee stock-based compensation in the periods ended June 30, 2023 or 2022.

*Options*. The Company has a single option award outstanding for 667 shares of our Common Stock for $33.75. This award is fully vested and remains effective until 90 days after the term ends of the individual trustee. The awards have no intrinsic value as they were out-of-the-money at June 30, 2023. No compensation expense was recognized for these awards in the periods ended June 30, 2023 or 2022 as the awards became fully vested in previous years.

------

**11.** **Income Taxes**

Income tax provisions for interim quarterly periods are generally based on an estimated annual effective income tax rate calculated separately from the effect of significant, infrequent or unusual items related specifically to interim periods. The income tax impacts of discrete items are recognized in the period these occur.

Our effective tax rate for the three months ended June 30, 2023 and 2022 was 0% and (52)%, respectively, and for the six months ended June 30, 2023 and 2022 was (3)% and 3%, respectively. The primary difference from the federal statutory rate of 21% in each period is related to state taxes and permanent differences for non-deductible expenses.

**12.** **Earnings (Loss) per Share**

The following is the computation of earnings (loss) per basic and diluted share:

In periods when we incur a net loss, the computation of diluted earnings per share for each of the periods above excludes shares issuable upon conversion of the Company's Class A Preferred Shares, Class C Preferred Shares and convertible notes payable because the effect of the conversions would be anti-dilutive. Similarly, outstanding options and restricted Common Shares were not included in the computation of diluted earnings per share for each of the periods above because they would be anti-dilutive.

**13.** **Related Party Transactions**

*Managerial Agreements.* From December 8, 2016 through August 18, 2022, we contracted with Whitestone TRS for managerial services and paid them managerial fees. On July 19, 2022, Pillarstone received written notice that Whitestone TRS confirmed termination of the Management Agreements for the Pillarstone OP Real Estate Assets. On August 18, 2022, Whitestone TRS ceased all managerial services without providing any transition services.

*Expense Reimbursements.* Under the Pillarstone OP Amended and Restated Agreement of Limited Partnership, Pillarstone OP is responsible for all expenses relating to its organization, the ownership of its assets and its operations. It is also responsible for the administrative and operating costs and expenses incurred by Pillarstone Capital REIT as its General Partner, including, without limitation, all expenses relating to the General Partner's (i) continued existence and subsidiary operations, (ii) offerings and registration of securities, (iii) preparation and filing of any periodic or other reports and communications required under federal, state or local laws and regulations, (iv) compliance with laws, rules and regulations promulgated by any regulatory body, and (v) operating or administrative costs incurred in the ordinary course of business on behalf of Pillarstone OP; provided, however, that such costs and expenses shall not include any administrative or operating costs of the General Partner attributable to assets owned by the General Partner directly and not through Pillarstone OP or its subsidiaries. We have no assets, activities or operations other than those related to Pillarstone OP.

------

Indemnification provisions within the Pillarstone OP Amended and Restated Agreement of Limited Partnership also provide for indemnification by Pillarstone of all losses, claims, damages, liabilities, joint or several, expenses (including, without limitation, attorneys fees and other legal fees and expenses), judgments, fines, settlements and other amounts, arising from or in connection with any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, relating to Pillarstone OP or the General Partner or the operation of, or the ownership of property in which an indemnitee may be involved, or is threatened to be involved, unless a court of competent jurisdiction establishes that indemnification is not permitted under the circumstances described in the Pillarstone OP Amended and Restated Agreement of Limited Partnership.

These reimbursement provisions have provided us with critical sources of cash and liquidity to maintain our operations. Following Whitestone's abrupt termination of managerial services to Pillarstone OP, we have incurred significant costs to internalize management and to select and implement an enterprise-wide system of our own. We have also incurred substantial legal costs in our litigation with Whitestone.

We determined that Whitestone, under the property Management Agreements in effect until August 2022, was not making appropriate reimbursement of the General Partner's operating and administrative expenses from Pillarstone OP. During the first quarter of 2022, we recorded $1.8 million as reimbursement of expenses for the years ended 2017 through 2021. We recorded reimbursements from Pillarstone OP totaling $559 thousand and $271 thousand in the six months ended June 30, 2023 and 2022, respectively, for operating and administrative expenses incurred.

The reimbursements initially reported in our Quarterly Reports on Forms 10-Q for the periods ended March 31, 2022 and June 30, 2022 were offset by reserves totaling $1.8 million because the amounts were disputed by Whitestone. We reversed the reserves in August 2022 after internalizing management and reaffirming our rights to the full reimbursement as provided by the Amended and Restated Agreement of Limited Partnership. Whitestone has notified us that they will contest some or all of these reimbursements. We intend to vigorously defend these reimbursements. For financial reporting purposes, Pillarstone REIT and Pillarstone OP report on a consolidated basis, therefore, the reimbursement of our expenses does not change net income but only the allocations between controlling and noncontrolling interests.

*Whitestone Claim for Expenses.* After we notified Whitestone of the $1.8 million reimbursement required from Pillarstone OP, Whitestone and Whitestone OP made a claim to Pillarstone and Pillarstone OP to be reimbursed for construction and lease commission expenditures of $1.4 million paid by Whitestone OP on behalf of Pillarstone OP during 2017 and 2018. Pillarstone requested additional information for the $1.4 million expenditures to determine if any of the items claimed should have been prorated between Pillarstone OP and Whitestone OP in our transaction with Whitestone and Whitestone OP on December 8, 2016 for the initial acquisition of the Real Estate Assets. These expenditures were recorded on Pillarstone OP in 2017 and 2018 as an increase in the Whitestone OP limited partner investment account and as assets of Pillarstone OP that have been depreciated and amortized to expense over their useful lives. As of June 30, 2023, the amount due Whitestone OP for these expenditures, if any, had not been determined. If Pillarstone OP reimburses any amounts to Whitestone OP, the payment would reduce the Whitestone OP limited partner investment account. Whitestone's claims were settled pursuant to the settlement agreement described in Part II, Item 1, "Legal Proceedings—Jointly Administered Bankruptcy Cases."

**14.** **Commitments and Contingencies**

We are party to lawsuits and bankruptcy filings discussed in detail below. This litigation has been and is expected to continue to be expensive, lengthy, and disruptive to normal business operations following the period covered by this report. Moreover, the results of these proceedings are difficult to predict.

As of June 30, 2023, the Company believes that the allegations in these lawsuits are without merit and intends to continue to vigorously defend against them. However, the outcomes of these lawsuits, including the timing of the final disposition of the lawsuits, are unpredictable. It is reasonably possible that these lawsuits could result in large monetary awards, especially if compensatory and/or punitive damages are awarded. Such damages may include a partial or complete loss of the value of the Company's interest in Pillarstone OP. Management, with the consultation of the Company's legal counsel, is not able to conclude whether these lawsuits will be resolved without a material adverse effect on our financial position, earnings, or cash flows.

*Delaware Lawsuit by Whitestone OP Against Us*.

On July 12, 2022, we were named as a defendant in a lawsuit by Whitestone OP in a lawsuit styled *Whitestone REIT Operating Partnership, L.P. v. Pillarstone Capital REIT,* C.A. No. 2022-0607-LWW, in the Court of Chancery of the State of Delaware. The suit challenged our rights agreement, dated as of December 27, 2021 (as the same may be amended from time to time, the "Rights Agreement"), between us and American Stock Transfer & Trust Company, LLC, as rights agent, and claimed that our adoption of the Rights Agreement breached the Pillarstone OP Amended and Restated Agreement of Limited Partnership, and that we breached our fiduciary duties as general partner of Pillarstone OP to Whitestone OP and breached the implied covenant of good faith and fair dealing under the Amended and Restated Agreement of Limited Partnership.

Based upon various issues, including those discussed in this report, we filed a lawsuit on September 16, 2022, in district court in Harris County, Texas, against Whitestone and related parties alleging, among other things, breach of the Pillarstone OP Amended and Restated Agreement of Limited Partnership and fiduciary duty and breach of the Management Agreements.

On July 21, 2022, Whitestone OP filed a Motion to Preserve the Status Quo in the Delaware lawsuit requesting broad restrictions on our ability to conduct our business, including buying properties, enforcing the Rights Agreement, incurring expenses, or engaging in transactions. The Status Quo Order also prevented Whitestone OP from exercising its right under the Pillarstone OP Amended and Restated Agreement of Limited Partnership to require Pillarstone OP to redeem its OP Units. Our amended petition in the Texas lawsuit argued that Whitestone's material breaches of contract and fiduciary duty operated to discharge and/or excuse any obligation to perform under the redemption provisions of the Pillarstone OP Amended and Restated Agreement of Limited Partnership.

Representatives of our board of trustees attempted to initiate discussions to settle these matters in August 2022 with representatives of Whitestone's board of trustees to avoid a prolonged, expensive legal fight. However, Whitestone was not open to settling these matters at that time or the other various times since August 2022 we attempted to initiate discussions to resolve these matters.

On July 17, 2023 and July 18, 2023, trial was held in the Delaware lawsuit. Post-trial argument in the lawsuit was held on October 18, 2023. Whitestone has asked the Delaware court to award damages of approximately $51,200,600 and post-judgement interest of $6,820,000 in the filing of its post-trial opening brief on August 28, 2023. On January 25, 2024, the Delaware court issued its opinion and determined that we breached the implied covenant of good faith and fair dealing without resolving the breach of contract or breach of fiduciary duty claims. Although Whitestone asked for monetary damages of $51,200,600 plus interest, the Delaware court declined to award damages.

The Delaware court declared the Rights Agreement unenforceable against Whitestone, permitted Whitestone OP to tender a notice of redemption for its OP Units and determined that the Pillarstone OP limited partnership agreement should be followed whereby we would decide whether to assume Pillarstone OP's redemption obligation and determine what value to attribute to Pillarstone OP's assets. The Delaware court declared that any further relief must await future proceedings. On January 25, 2024, Whitestone OP delivered its notice of redemption for all but one of its OP Units. The claims in this case were settled pursuant to the settlement agreement described in "—Bankruptcy Filings" below.

*Our Texas Lawsuit against Whitestone*.

Our executive management team worked to restore normal operations and leasing activities quickly after Whitestone's unanticipated termination of their managerial services. Many of our actions were affected by a lack of usable information being made available to us on a timely basis. We discovered significant deferred maintenance and neglect of our assets had occurred under Whitestone's management. Our efforts to address these matters were in some cases stymied by Whitestone's litigation against us in Delaware where the court limited our ability to incur expenses above low threshold amounts for the types of expenses a company in our industry could expect to incur in the ordinary course of business. Our legal and professional fees have increased substantially as we address the internalization of management and the litigation matters discussed above.

------

On September 16, 2022, we filed a lawsuit styled *Pillarstone Capital REIT and Pillarstone Capital REIT Operating Partnership LP v. Whitestone TRS, Inc., Whitestone REIT, Whitestone REIT Operating Partnership, L.P.,* Cause No. 2022-59478, in the District Court, Harris County, Texas, 189th Judicial District alleging, among other things, breach of the Pillarstone OP limited partnership agreement and the Management Agreements for the Real Estate Assets by the Whitestone defendants and breach of fiduciary duties relating to Pillarstone OP by Whitestone OP going outside the role of limited partner and harming us and Pillarstone OP. A portion of the claims in this case were moved into an adversary proceeding by Whitestone Uptown Tower, LLC in the Uptown Tower bankruptcy case described in "—Bankruptcy Filings" below, and the other claims were settled pursuant to the settlement agreement described in "—Bankruptcy Filings" below.

*Bankruptcy Filings*.

On December 1, 2023, Whitestone Uptown Tower, LLC filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Northern District of Texas in the case styled *In re: Whitestone Uptown Tower, LLC a/a/ Pillarstone Capital REIT Operating Partnership*, Case No. 23-32832-mvl-11, in the United States Bankruptcy Court for the Northern District of Texas, Dallas Division.

On March 4, 2024, bankruptcy cases were filed for us and Pillarstone OP, as well as Whitestone CP Woodland Ph. 2, LLC, Whitestone Industrial-Office, LLC and Whitestone Offices, LLC, the subsidiaries owning our Real Estate Assets other than Uptown Tower. The bankruptcy cases were consolidated into the jointly administered bankruptcy cases styled *In re: Whitestone Industrial-Office, LLC, et. al.*, Case No. 24-30653-mvl-11, in the United States Bankruptcy Court for the Northern District of Texas, Dallas Division, the same court as, but separate cases from, the Whitestone Uptown Tower, LLC bankruptcy case.

The bankruptcy cases proceeded under an approved plan of liquidation in the jointly administered bankruptcy cases and an approved plan of reorganization in the Uptown Tower bankruptcy case. The plan of liquidation in the jointly administered bankruptcy cases provided for a plan agent, and Frances A. Smith was appointed plan agent. The plan agent was appointed for the purposes of administering all claims in the plan of liquidation in the jointly administered bankruptcy cases and making distributions to holders of allowed claims and equity interests under the plan of liquidation in the jointly administered bankruptcy cases. The plan agent's administration of the claims may include, without limitation, and pursuant to her reasonable business judgment, investigating, prosecuting, objecting to, resolving, reconciling, compromising, litigating, administering, and making distributions on account of, the claims.

The plan agent is not a trustee and does not participate in the management or operations of the debtors' businesses, assets or financial affairs or the review and approval of the day-to-day operational expenses of the debtors' business post-confirmation, unless the bankruptcy court determines cause exists for the plan agent to do so after notice and hearing.

The plan agent has the sole and exclusive authority to administer the claims in the jointly administered bankruptcy cases, including the determination to compromise a claim involving Whitestone OP, any debtor or their affiliates or professionals, subject to notice and hearing and a party's good-faith objection and the bankruptcy court's final adjudication of the matter. The plan agent also has the authority to make demand on the debtors for funds necessary to satisfy allowed claims asserted against a debtor from that debtor's funds (even if held by Pillarstone OP), which may include sales proceeds.

The plan agent is entitled to receive compensation as a flat fee of $10,000 per month, plus reimbursement of actual, necessary expenses. If during any month the plan agent spends more than fifteen (15) hours in the performance of her duties, she will be entitled to compensation at a rate of $650 per hour for each additional hour of services.

The plan of liquidation in the jointly administered bankruptcy cases and the plan of reorganization in the Uptown Tower bankruptcy case authorized the sale of all of our properties. Those properties were sold between October 2024 and July 2025. Our debts have been repaid from the proceeds from these sales of our Real Estate Assets in accordance with our plan of liquidation and the Whitestone Uptown Tower, LLC plan of reorganization following the period covered by this report.

In December 2025 over our objections, the bankruptcy court in the jointly administered bankruptcy cases issued an order approving an agreement between the plan agent and Whitestone REIT, Whitestone OP and Whitestone TRS settling the Whitestone claims in the jointly administered bankruptcy cases. The plan agent and Whitestone negotiated the settlement agreement without our participation. The bankruptcy court's order and the settlement agreement provided for, among other things:

● Allowed Claims (as defined in the plan of liquidation) of Whitestone Industrial-Office, LLC, Whitestone Offices, LLC and Whitestone CP Woodland Ph. 2, LLC (the "Subsidiary Debtors") shall be satisfied by payment in full from the Subsidiary Debtors. At the direction of the plan agent, the debtors shall make such payments to holders of Allowed Claims of the Subsidiary Debtors. After payment of the Allowed Claims of the Subsidiary Debtors, all remaining funds (the "<u>Partnership Estate Funds</u>") shall flow to the Pillarstone OP estate.

● the debtors shall use Partnership Estate Funds to establish the following three reserves to support the plan agent's claim administration process:

------

---

| | |
|:---|:---|
| o | the debtors shall use $1,000,000.00 of the Partnership Estate Funds to establish the "Partnership Tax Reserve". The plan agent shall direct the debtors to use the Partnership Tax Reserve to satisfy state and federal tax claims owed by Pillarstone OP and us. The debtors shall make such payments as directed by the plan agent; |

---

---

| | |
|:---|:---|
| o | the debtors shall use $1,000,000.00 of the Partnership Estate Funds to establish the "Case Administration Reserve". The plan agent shall direct the debtors to use the Cash Administration Reserve to fund estate administrative expenses including payment of estate employees, attorneys' fees, accounting fees, costs of administering claims, and winding up the estates of us, Pillarstone OP and the Subsidiary Debtors (together, the "Debtors Estates"). The debtors shall make such payments as directed by the plan agent; and |

---

---

| | |
|:---|:---|
| o | the debtors shall use $500,000.00 of the Partnership Estate Funds to establish the "Partnership GUC Reserve". The plan agent shall direct the debtors to use the Partnership GUC Reserve to satisfy all allowed general unsecured claims, including insider general unsecured claims, against Pillarstone OP. The debtors shall make such payments as directed by the plan agent. Should the debtors fail to make payment as directed, the plan agent shall seek relief from the Bankruptcy Court; |

---

● the debtors shall distribute $4,050,000.00 to the Pillarstone Capital REIT estate (the "Pillarstone Distribution") from the Partnership Estate Funds in satisfaction of all outstanding claims by us against the Pillarstone OP estate. The plan agent shall administer claims against our estate and shall direct the debtors to satisfy any allowed claims against our estate with the Pillarstone Distribution and any other cash in our estate. The plan agent shall direct the debtors to distribute any surplus proceeds remaining from the Pillarstone Distribution to our equity interest holders in accordance with the plan of liquidation in the jointly administered bankruptcy cases. This distribution was made in December 2025;

● following the satisfaction of all the claims of the Subsidiary Debtors, and of the reserves set forth above, the debtors shall distribute all funds remaining in the Pillarstone OP estate to Whitestone OP no later than December 12, 2025. This payment (the "WROP Distribution") was made in December 2025;

● the plan agent shall direct the debtors to distribute any surplus funds from the Partnership Tax Reserve, Case Administrative Reserve, and Partnership Tax Reserve remaining after the complete administration of the Debtors' Estates to Whitestone OP. The debtors shall make such Surplus Reserve Funds payments as directed by the plan agent;

● upon entry of the final order approving the motion to approve the settlement, the plan agent and Whitestone OP shall promptly move to dismiss with prejudice:

---

| | |
|:---|:---|
| o | the adversary proceeding commenced by Pillarstone OP in the jointly administered bankruptcy cases; |

---

---

| | |
|:---|:---|
| o | the Houston litigation discussed in Part II, Item 1 "Legal Proceedings—Houston Case"; and |

---

---

| | |
|:---|:---|
| o | the Delaware litigation discussed in Part II, Item 1 "Legal Proceedings —Delaware Case"; |

---

● upon entry of the final order, and payment of the WROP Distribution, Whitestone OP shall (a) move to dismiss with prejudice all pending litigation initiated by it against any of the debtors, and (b) withdraw its proof of claim against Pillarstone OP in the amount of $52,963,904.83 and its proof of claim against Pillarstone Capital REIT in the amount of $9,966,778.64;

● the plan agent, on behalf of the debtors and the Debtors Estates, granted a release to Whitestone REIT, Whitestone OP, Whitestone TRS and certain of their related parties and agreed to ensure the dismissal with prejudice of all pending claims, causes of action and lawsuits brought by any of the debtors against such parties. The Whitestone parties granted releases to the plan agent and the Debtors Estates and agreed to ensure the dismissal with prejudice of all pending claims, causes of actions and lawsuits against any of the debtors, including the Delaware litigation. Whitestone OP agreed to dismiss its claims and causes of action against James C. Mastandrea pending in his adversary claims in the jointly administered bankruptcy cases to the extent he is seeking indemnification against the Debtors Estates on account of those claims; and

● the bankruptcy court shall retain exclusive personal and subject matter jurisdiction to enforce the terms of the settlement agreement and to decide any claims or disputes that may arise or result from, or be connected with, the settlement agreement, or any breach or default thereunder.

Whitestone Uptown Tower, LLC was not party or subject to the settlement, and the litigation in its bankruptcy case was not resolved under the settlement.

We cannot predict or quantify the ultimate impact that events occurring during the bankruptcy process may have on our business, financial condition and results of operations, and there is no certainty as to our ability to continue as a going concern.

**15.** **Subsequent Events**

• the impact of a public health crisis and the governmental and third-party response to such a crisis, which may affect our key personnel, our tenants, and the costs of operating our assets;

• changes in the needs of our tenants brought about by the desire for co-working arrangements, trends toward utilizing less office space per employee, and the effect of employees working remotely;

• sociopolitical unrest such as political instability, civil unrest, armed hostilities, or political activism, which may result in a disruption of day-to-day building operations;

• increases in interest rates and operating costs;

• availability and terms of capital and financing, both to fund our operations and to refinance any indebtedness as it matures, in each case, on terms favorable to us;

------

• decreases in rental rates or increases in vacancy rates;

• litigation risks;

• volatility in interest rates and insurance rates;

• inflation and continuing increases in the inflation rate;

• the risks associated with real estate developments (such as zoning approval, receipt of required permits, construction delays, cost overruns, and leasing risk);

• changes in senior management, changes in the Board of Trustees, and the loss of key personnel;

• the potential liability for uninsured losses, condemnation, or environmental issues;

• the potential liability for a failure to meet regulatory requirements;

• any failure to comply with debt covenants under credit agreements;

• potential changes to state, local, or federal regulations applicable to our business;

• cybersecurity attacks, loss of confidential information and other business disruptions; and

• our inability to generate sufficient cash flows due to market conditions, competition, uninsured losses, changes in tax or other applicable laws.

In addition, an investment in the Company involves numerous risks that potential investors should consider carefully, including, without limitation:

• our cash resources are limited;

• we have a history of losses;

• we have not raised funds through a public equity offering;

• our trustees control a significant percentage of our voting shares;

• shareholders could experience possible future dilution through the issuance of additional shares;

• we are dependent on a small number of key senior professionals; and

• we currently do not plan to distribute dividends to the holders of our shares.

**Overview**

We are a Maryland real estate investment trust ("REIT") engaged in investing in, owning and operating commercial properties. As of June 30, 2023, we owned approximately 18.6% of Pillarstone Capital REIT Operating Partnership LP ("Pillarstone OP") and serve as its general partner. Substantially all of our operations and activities are conducted for the benefit of and through Pillarstone OP. As the general partner of Pillarstone OP, we had the exclusive power to manage and conduct the business of Pillarstone OP, subject to certain customary exceptions. As of June 30, 2023, Pillarstone OP owned two office buildings in the Dallas metropolitan area and six office/warehouse and retail locations in the Houston metropolitan area having approximately 927 thousand square feet of gross leasable area.

Following the period covered by this report, we sold all of our Real Estate Assets described below pursuant to the plan of liquidation in the jointly administered bankruptcy cases for us and Pillarstone OP, as well as Whitestone CP Woodland Ph. 2, LLC, Whitestone Industrial-Office, LLC and Whitestone Offices, LLC, the subsidiaries owning our Real Estate Assets other than Uptown Tower, and the plan of reorganization in the separate bankruptcy case for our Whitestone Uptown Tower, LLC subsidiary. We are considering our strategic plans following the outcome of the bankruptcy cases.

***History***

Pillarstone was formed on March 15, 1994 as a Maryland REIT. We operated as a traditional REIT by buying, selling, owning and operating commercial and residential properties through December 31, 1999. In 2000, we purchased a software technology company, resulting in our not meeting the qualifications to be a REIT under the Code. In 2002, we discontinued the operations of the technology segment, and from 2003 through 2006, pursued a value-added business plan primarily focused on acquiring well located, under-performing multifamily residential properties, including affordable housing communities, and repositioning them through renovation, leasing, improved management and branding. From 2006 until December 2016, we continued our existence as a corporate shell current in our SEC filings.

On December 8, 2016, Pillarstone and Pillarstone OP entered into the Contribution Agreement with Whitestone OP, a subsidiary and the operating partnership of Whitestone REIT, both of which were related parties to us and Pillarstone OP, pursuant to which Whitestone OP contributed to Pillarstone OP all of the equity interests in four of its wholly-owned subsidiaries that owned 14 real estate assets (the "Real Estate Assets") for aggregate consideration of approximately $84 million, consisting of (1) approximately $18.1 million of Class A units representing limited partnership interests in Pillarstone OP issued at a price of $1.331 per OP Unit; and (2) the assumption of approximately $65.9 million of liabilities by Pillarstone OP (collectively, the "Acquisition"). Whitestone OP was the 81.4% limited partner of Pillarstone OP following the transaction.

In connection with the Contribution Agreement, on December 8, 2016, we entered into management agreements with Whitestone TRS, Inc., a subsidiary of Whitestone ("Whitestone TRS"). Pursuant to the management agreements, Whitestone TRS agreed to provide certain property management, leasing and day-to-day advisory and administrative services to such properties in exchange for monthly property and asset management fees.

On July 19, 2022, we received written notice that Whitestone TRS confirmed termination of the management agreements for the Real Estate Assets. We had previously communicated to Whitestone our plan to internalize the management of the Real Estate Assets, but we had not made efforts to terminate the management agreements. However, Whitestone TRS stated in its notice letter that while it had not received written notice of the termination of the management agreements, it "confirms receipt of your intent to terminate, and hereby confirms termination of the Agreements effective 30 days from" July 19, 2022. The management agreements provided that "Unless otherwise terminated pursuant to the provisions hereof, the term of this Agreement shall automatically renew on a month to month basis at the end of the term unless either of the Parties has notified the other in writing not less than thirty (30) days prior to the expiration of the term, as the same may be extended."

Prior to receiving the termination notice, we had anticipated an orderly transition of the management of the Real Estate Assets over an appropriate timeframe. The management agreements provided for Whitestone TRS to provide such services, or in certain cases contracting with other providers to perform such services, as:

• providing management, leasing, and maintenance personnel to operate the Real Estate Assets;

• maintaining the Real Estate Assets;

• maintaining connected utility services at the Real Estate Assets;

• invoice and collect the monthly rent from the tenants; default and pursue collection for delinquent tenants;

• pay monthly invoices to vendors, including loan payments to lenders;

• maintain monthly accounting records and provide monthly operating statements for each Real Estate Asset;

• perform an annual audit of the financial statements, prepare workpapers for the annual audit, and assist the auditors to complete the annual audit;

• assist in the preparation of the annual tax returns for Pillarstone, Pillarstone OP and the owners of the Real Estate Assets; and

• assist in the preparation of the Pillarstone SEC financial reports and other filings.

We worked diligently to restore normal operations and leasing activities following Whitestone's unanticipated termination of its managerial services. Many of our actions were affected by a lack of usable information made available to us by Whitestone on a timely basis. Prior to receiving the termination notice, we had anticipated an orderly transition of the management of the Real Estate Assets over an appropriate timeframe, particularly as Whitestone OP owned 81.4% of Pillarstone OP as a non-controlling limited partner.

Whitestone's 30-day notice period of termination was insufficient. Whitestone did not cooperate with us to provide for an orderly transition of its contracted responsibilities. The services under the management agreements were extensive and material to the operation of Pillarstone's business and our accounting and financial reporting. The management functions, as operated by Whitestone, were deeply co-mingled with Whitestone's management functions for its own business. As a result, Pillarstone was materially and adversely affected by Whitestone's abrupt termination of the management agreements, its incomplete and inadequate delivery of books and records and other materials required to be delivered under the management agreements, and the failure to provide for an appropriate transition. We had no way to continue our accounting and financial reporting responsibilities as a public company. For several months following the abrupt termination of services by Whitestone, we were unable to systematically invoice our tenants and pursue collection of delinquent accounts as an independent, internally-managed company. In addition, several vendor service contracts were tied to Whitestone and the pricing of services was based on the combination of Pillarstone and Whitestone. The transition caused us to obtain separate services, which caused delays in our business operations and higher costs. In other cases, Whitestone obligated us to long-term contracts for essential services that we cannot easily replace.

------

Specifically, Whitestone:

• removed our access to all operations, accounting, and financial reporting systems intentionally causing harm to landlord-tenant relations at all of our properties. They immediately ceased daily accounting responsibilities and exported our general ledger history into disparate and unorganized Microsoft Excel files;

• copied more than 27,000 files into poorly organized and incomplete electronic folders containing Adobe PDF, Microsoft Excel and other file formats not easily available, and in some situations not readable by industry standard software, as source documents or historical filings and accounting records;

• ceased daily managerial responsibilities without documentation of key processes and communicating the status of incomplete items;

• neglected routine proper maintenance of the Real Estate Assets while under their management; and

• left the Real Estate Assets with numerous tenant life and health safety concerns requiring our immediate attention to correct; specifically, infestations, long ignored roof leaks causing property and mold damage, and electrical, water and security systems neglect.

Within days after the termination of the management agreements by Whitestone, we internalized management and began to manage our Real Estate Assets and our business without an external management company. Our board of trustees immediately hired an experienced executive management team with prior experience working with our property portfolio and our leadership team quickly began:

• recruiting and engaging consultants and employees for maintenance and leasing of our Real Estate Assets;

• evaluating the life safety and deferred maintenance issues that arose and were inadequately addressed, if at all, by Whitestone during the term of the management agreements;

• communicating with tenants and vendors regarding the change in management. The abrupt termination of the management agreements caused some confusion among tenants and vendors regarding payment issues and responsibility to take actions. We learned that many tenants were not pleased with the services they received from Whitestone during the term of the management agreements and have tried to assure the tenants that the internalization of management will lead to improvements for them. In addition, we began transitioning vendor relationships from entangled transactions with Whitestone properties arising from arrangements and contracts Whitestone entered into during the term of the management agreements. For example, on August 19, 2022, Whitestone dropped our properties from their insurance, and we had to obtain a separate insurance and risk management package; and

• evaluating the redevelopment plans available to us that were developed but left dormant during the term of the management agreements. Whitestone neglected to provide us with all of the redevelopment plans for our property portfolio.

We selected an enterprise resource planning, or ERP, system of our own and began implementation which continued into 2023. Our leadership team quickly engaged consultants (a) to assist us in implementing the newly selected ERP system, (b) to analyze, reconcile and transform historical data obtained from Whitestone into a usable format for our new system and (c) to design procedures for regular accounting closes and preparation of accurate and reliable financial statements for our shareholders and other stakeholders. While this process has been underway, we have been directing the maintenance and operations of the Real Estate Assets and taking steps available to us to address the significant deferred maintenance and neglect of our assets which occurred while under Whitestone's management.

***Lawsuits, Bankruptcy Proceedings and Sale of Our Properties***

On July 12, 2022, we were named as a defendant in a lawsuit by Whitestone OP in a lawsuit styled *Whitestone REIT Operating Partnership, L.P. v. Pillarstone Capital REIT,* C.A. No. 2022-0607-LWW, in the Court of Chancery of the State of Delaware. The suit challenged our rights agreement, dated as of December 27, 2021 (as the same may be amended from time to time, the "Rights Agreement"), between us and American Stock Transfer & Trust Company, LLC, as rights agent, and claimed that our adoption of the Rights Agreement breached the Pillarstone OP Amended and Restated Agreement of Limited Partnership, and that we breached our fiduciary duties as general partner of Pillarstone OP to Whitestone OP and breached the implied covenant of good faith and fair dealing under the Amended and Restated Agreement of Limited Partnership.

------

Based upon various issues, including those discussed in this report, we filed a lawsuit on September 16, 2022, in district court in Harris County, Texas, against Whitestone and related parties alleging, among other things, breach of the Pillarstone OP Amended and Restated Agreement of Limited Partnership and fiduciary duty and breach of the management agreements.

On July 21, 2022, Whitestone OP filed a Motion to Preserve the Status Quo in the Delaware lawsuit requesting broad restrictions on our ability to conduct our business, including buying properties, enforcing the Rights Agreement, incurring expenses, or engaging in transactions. The Status Quo Order also prevented Whitestone OP from exercising its right under the Pillarstone OP Amended and Restated Agreement of Limited Partnership to require Pillarstone OP to redeem its OP Units. Our amended petition in the Texas lawsuit argued that Whitestone's material breaches of contract and fiduciary duty operated to discharge and/or excuse any obligation to perform under the redemption provisions of the Pillarstone OP Amended and Restated Agreement of Limited Partnership.

Representatives of our board of trustees attempted to initiate discussions to settle these matters in August 2022 with representatives of Whitestone's board of trustees to avoid a prolonged, expensive legal fight. However, Whitestone was not open to settling these matters at that time or the other various times since August 2022 we attempted to initiate discussions to resolve these matters.

Whitestone indicated to us its intent to cause Whitestone OP to exercise its redemption right and stated publicly that it intended to monetize its investment in Pillarstone OP. We believed that if Whitestone were to be permitted to exercise its redemption right for cash amounts, we may not have the cash available to pay such amounts and may be required to sell one or more of our Real Estate Assets to satisfy this obligation, which may cause us to sell some or all of our Real Estate Assets at below fair market value and otherwise have a material adverse effect on our liquidity and financial condition and our ability to operate and improve our Real Estate Assets. We stated that a redemption request would not trigger the Rights Agreement, and our board of trustees had the sole discretion to interpret the Rights Agreement. However, Whitestone OP indicated that the Rights Agreement caused them to not exercise their redemption rights and claimed damages based on the alleged decline in the value of the Real Estate Assets following their failure to exercise the redemption rights.

Based on Whitestone's performance under the management agreements and their public statements regarding their intentions for their interest in Pillarstone, we did not believe that Whitestone's actions in connection with the exercise of the redemption rights would respect the rights of the holders of our common shares. The Pillarstone OP Amended and Restated Agreement of Limited Partnership expressly provides that in the event of a conflict between the interests of the limited partners (Whitestone OP as the sole limited partner) and our shareholders, we shall act in the interests of our shareholders, and we shall not be liable for monetary or other losses sustained, liabilities incurred or benefits not derived by the limited partners in connection therewith.

On September 16, 2022, we filed a lawsuit styled *Pillarstone Capital REIT and Pillarstone Capital REIT Operating Partnership LP v. Whitestone TRS, Inc., Whitestone REIT, Whitestone REIT Operating Partnership, L.P.,* Cause No. 2022-59478, in the District Court, Harris County, Texas, 189th Judicial District alleging, among other things, breach of the Pillarstone OP limited partnership agreement and the management agreements for the Real Estate Assets by the Whitestone defendants and breach of fiduciary duties relating to Pillarstone OP by Whitestone OP going outside the role of limited partner and harming us and Pillarstone OP. A portion of the claims in this case were moved into an adversary proceeding by Whitestone Uptown Tower in the Uptown Tower bankruptcy case described in Part II, Item 1, "Legal Proceedings—Uptown Tower", and the remaining claims in the Houston case were settled pursuant to the settlement agreement described in Part II, Item 1, "Legal Proceedings—Jointly Administered Bankruptcy Cases".

Our executive management team worked to restore normal operations and leasing activities quickly after Whitestone's unanticipated termination of their managerial services. Many of our actions were affected by a lack of usable information being made available to us on a timely basis.

We discovered significant deferred maintenance and neglect of our assets had occurred under Whitestone's management. Our efforts to address these matters were in some cases stymied by Whitestone's litigation against us in Delaware where the court limited our ability to incur expenses above low threshold amounts for the types of expenses a company in our industry could expect to incur in the ordinary course of business. Our legal and professional fees increased substantially as we addressed the internalization of management and the litigation matters discussed in this report.

On July 17, 2023 and July 18, 2023, trial was held in the Delaware lawsuit. Post-trial argument in the lawsuit was held on October 18, 2023. Whitestone has asked the Delaware court to award damages of approximately $51,200,600 and post-judgement interest of $6,820,000 in the filing of its post-trial opening brief on August 28, 2023. On January 25, 2024, the Delaware court issued its opinion and determined that we breached the implied covenant of good faith and fair dealing without resolving the breach of contract or breach of fiduciary duty claims. Although Whitestone asked for monetary damages of $51,200,600 plus interest, the Delaware court declined to award damages. The Delaware court declared the Rights Agreement unenforceable against Whitestone, permitted Whitestone OP to tender a notice of redemption for its OP Units and determined that the Pillarstone OP limited partnership agreement should be followed whereby we would decide whether to assume Pillarstone OP's redemption obligation and determine what value to attribute to Pillarstone OP's assets. The Delaware court declared that any further relief must await future proceedings.

------

On January 25, 2024 Whitestone OP delivered its notice of redemption for all but one of its OP Units.

On March 4, 2024, bankruptcy cases were filed for us and Pillarstone OP, as well as Whitestone CP Woodland Ph. 2, LLC, Whitestone Industrial-Office, LLC and Whitestone Offices, LLC, the subsidiaries owning our Real Estate Assets other than Uptown Tower. The bankruptcy cases were consolidated into the jointly administered bankruptcy cases styled *In re: Whitestone Industrial-Office, LLC, et. al.*, Case No. 24-30653-mvl-11, in the United States Bankruptcy Court for the Northern District of Texas, Dallas Division, the same court as, but separate cases from, the Whitestone Uptown Tower, LLC bankruptcy case.

The plan of liquidation in the jointly administered bankruptcy cases providing for the sale of the Real Estate Assets other than Uptown Tower and treatment of claims was confirmed in November 2024. Those Real Estate Assets were sold between October 2024 and July 2025.

The plan provided for a plan agent, and Frances A. Smith was appointed plan agent in the jointly administered bankruptcy cases. The plan agent was appointed for the purposes of administering all claims in the bankruptcy cases and making distributions to holders of allowed claims and equity interests under the plan of liquidation. The plan agent's administration of the claims may include, without limitation, and pursuant to her reasonable business judgment, investigating, prosecuting, objecting to, resolving, reconciling, compromising, litigating, administering, and making distributions on account of, the claims.

The plan agent is not a trustee and does not participate in the management or operations of the debtors' businesses, assets or financial affairs or the review and approval of the day-to-day operational expenses of the debtors' business post-confirmation, unless the bankruptcy court determines cause exists for the plan agent to do so after notice and hearing.

The plan agent has the sole and exclusive authority to administer the claims, including the determination to compromise a claim involving Whitestone OP, any debtor or their affiliates or professionals, subject to notice and hearing and a party's good-faith objection and the bankruptcy court's final adjudication of the matter. The plan agent also has the authority to make demand on the debtors for funds necessary to satisfy allowed claims asserted against a debtor from that debtor's funds (even if held by Pillarstone OP), which may include sales proceeds.

The plan agent is entitled to receive compensation as a flat fee of $10,000 per month, plus reimbursement of actual, necessary expenses. If during any month the plan agent spends more than fifteen (15) hours in the performance of her duties, she will be entitled to compensation at a rate of $650 per hour for each additional hour of services.

In December 2025, the plan agent and Whitestone REIT, Whitestone OP and Whitestone TRS entered into a settlement agreement discussed in "—Liquidity and Capital Resources" below.

Following the period covered by this report, we sold all of our Real Estate Assets. We are considering our strategic plans following the outcome of the proceedings in the bankruptcy cases.

**Results of Operations**

The following discussion of our results of operations should be read in conjunction with the consolidated financial statements and notes thereto appearing elsewhere in this report.

***Comparison of the Three Months Ended June 30, 2023 and 2022***

The following provides a comparison of our results of operations (dollars in thousands):

---

| | | |
|:---|:---|:---|
|  | **Three Months Ended June 30,** | **Three Months Ended June 30,** |
|  | **2023** | **2022** |
| Number of properties | 8 | 8 |
| Aggregate GLA (sq. ft.) | 926798 | 926798 |
| Ending occupancy rate | 51% | 56% |
| Total revenues | $2112 | $2278 |
| Total operating expenses | 2900 | 2099 |
| Total other expenses | 156 | 202 |
| Provision for income tax expense (benefit) |  | (12) |
| Net income (loss) | (944) | (11) |
| Less: Non-controlling interest in subsidiary | (949) | 64 |
| Net income (loss) attributable to Common Shareholders | $5 | $(75) |

---

*Revenues.* Total revenues for the three months ended June 30, 2023 were $2.1 million as compared with $2.3 million for the same period of 2022. The decrease of $166 thousand or 7% was principally caused by a decline in occupancy rates from 56% at June 30, 2022 to 51% at June 30, 2023. Leasing activity was adversely affected by Whitestone's unexpected termination of their managerial services in August 2022.

In July 2022, Whitestone terminated leases with us for approximately 30,000 square feet at four Real Estate Assets that it maintained as it acted as manager of the Real Estate Assets. This impact was particularly notable at our Uptown Tower property where Whitestone leased approximately 1,800 square feet of office space and an additional 15,822 square feet for its Cubexec executive office business. Whitestone's lease terminations also included 8,231 square feet of space at the LBJ building for its Cubexec executive office business. As Whitestone vacated the terminated leased properties, it removed critical items needed for the Cubexec customers while requesting that we take over its agreements with those customers. We subsequently restored the executive office offering at Uptown Tower and LBJ and worked to restore normal operations across our portfolio since Whitestone's abrupt termination of leases and management services. We also believe that Whitestone used other portions of our Holly Hall and Corporate Park Northwest properties for their storage and for other Whitestone purposes without paying rent or maintaining those areas in suitable condition for third party tenants, also impacting our occupancy before and after the termination of Whitestone's management services.

*Expenses.* Our operating expenses were $2.9 million for the three months ended June 30, 2023 compared to $2.1 million for the same period of 2022, an increase of $801 thousand, or 38%. The overall increase was primarily due to legal expenses incurred for the lawsuits with Whitestone and contract accounting services and other costs as we internalized management after Whitestone's unexpected termination of managerial services. The primary components of operating expenses are detailed in the table below (in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Three Months Ended June 30,** | **Three Months Ended June 30,** |  |  |
|  | **2023** | **2022** | **Change** | **% Change** |
| Depreciation and amortization | $499 | $506 | $(7) | -1% |
| Operating and maintenance | 837 | 852 | (15) | -2% |
| Real estate taxes | 367 | 413 | (46) | -11% |
| General and administrative | 970 | 185 | 785 | 424% |
| Management fees | 227 | 143 | 84 | 59% |
| Total operating expenses | $2900 | $2099 | $801 | 38% |

---

Our effective tax rate for the three months ended June 30, 2023 and 2022 was 0% and (52)%, respectively. The primary difference from the federal statutory rate of 21% in each period is related to state taxes and permanent differences for non-deductible expenses.

Noncontrolling interest in subsidiary represents the share earnings of Pillarstone OP allocable to holders of partnership interests other than us.

**Comparison of the Six Months Ended June 30, 2023 and 2022**

The following provides a general comparison of our results of operations (dollars in thousands):

|:---|:---|:---|
|  | **Six Months Ended June 30,** | **Six Months Ended June 30,** |
|  | **2023** | **2022** |

| Aggregate GLA (sq. ft.) | 926798 | 926798 |
| Ending occupancy rate | 51% | 56% |
| Total revenues | $4227 | $4604 |
| Total operating expenses | 5522 | 4009 |
| Total other expenses | 419 | 399 |
| Provision for income tax expense (benefit) | (45) | (5) |
| Net income (loss) | (1669) | 201 |
| Less: Non-controlling interest in subsidiary | (1420) | 293 |
| Net income (loss) attributable to Common Shareholders | $(249) | $(92) |

---

***Revenues.*** We had total revenues for the six months ended June 30, 2023 and 2022 of $4.2 million and $4.6 million, respectively, a decrease of $377 thousand, or 8%. The decrease was principally caused by a decline in average occupancy rates in the six months ended June 30, 2023. Leasing activity was adversely affected by Whitestone's unexpected termination of their managerial services in August 2022.

In addition, in July 2022, Whitestone terminated leases with us for approximately 30,000 square feet at four Real Estate Assets that it maintained as it acted as manager of the Real Estate Assets. This impact was particularly notable at our Uptown Tower property where Whitestone leased approximately 1,800 square feet of office space and an additional 15,822 square feet for its Cubexec executive office business. Whitestone's lease terminations also included 8,231 square feet of space at the LBJ building for its Cubexec executive office business. As Whitestone vacated the terminated leased properties, it removed critical items needed for the Cubexec customers while requesting that we take over its agreements with those customers. We have subsequently restored the executive office offering at Uptown Tower and LBJ and worked to restore normal operations across our portfolio since Whitestone's abrupt termination of leases and management services. We also believe that Whitestone used other portions of our Holly Hall and Corporate Park Northwest properties for their storage and for other Whitestone purposes without paying rent or maintaining those areas in suitable condition for third party tenants, also impacting our occupancy before and after the termination of Whitestone's management services.

***Expenses.*** Our operating expenses were approximately $5.5 million for the six months ended June 30, 2023 compared to $4.0 million the same period of 2022, an increase of approximately $1.5 million, or 38%. The overall increase was primarily due to legal expenses incurred for the lawsuits with Whitestone and contract accounting services and other costs as we internalized management after Whitestone's unexpected termination of managerial services. The primary components of operating expenses are detailed in the table below (in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Six Months Ended June 30,** | **Six Months Ended June 30,** |  |  |
|  | **2023** | **2022** | **Change** | **% Change** |
| Depreciation and amortization | $985 | $990 | $(5) | -1% |
| Operating and maintenance | 1474 | 1623 | (149) | -9% |
| Real estate taxes | 792 | 741 | 51 | 7% |
| General and administrative | 1851 | 372 | 1479 | 398% |
| Management fees | 420 | 283 | 137 | 48% |
| Total operating expenses | $5522 | $4009 | $1513 | 38% |

---

Our effective tax rate for the six months ended June 30, 2023 and 2022 was (3)% and 3%, respectively. The primary difference from the federal statutory rate of 21% in each period is related to state taxes and permanent differences for non-deductible expenses.

Noncontrolling interest in subsidiary represents the share earnings of Pillarstone OP allocable to holders of partnership interests other than us.

------

**Liquidity and Capital Resources** 

As of June 30, 2023, our unrestricted cash resources were $3.3 million.

*Significant sources and uses of cash during the six months ended June 30, 2023.*

● Cash used for operating activities was $598 thousand.

● We received $253 thousand of insured loss reimbursements for elevator damage at Uptown Tower.

● Capital expenditures were $1.1 million principally for elevator repairs at Uptown Tower and other health and safety needs at our properties.

● We made repayments of notes payable totaling $396 thousand.

*Expense Reimbursements.* Under the Pillarstone OP Amended and Restated Agreement of Limited Partnership, Pillarstone OP is responsible for all expenses relating to its organization, the ownership of its assets and its operations. It is also responsible for the administrative and operating costs and expenses incurred by Pillarstone Capital REIT as its General Partner, including, without limitation, all expenses relating to the General Partner's (i) continued existence and subsidiary operations, (ii) offerings and registration of securities, (iii) preparation and filing of any periodic or other reports and communications required under federal, state or local laws and regulations, (iv) compliance with laws, rules and regulations promulgated by any regulatory body, and (v) operating or administrative costs incurred in the ordinary course of business on behalf of Pillarstone OP; provided, however, that such costs and expenses shall not include any administrative or operating costs of the General Partner attributable to assets owned by the General Partner directly and not through Pillarstone OP or its subsidiaries. We have no assets, activities or operations other than those related to Pillarstone OP.

Indemnification provisions within the Pillarstone OP Amended and Restated Agreement of Limited Partnership also provide for indemnification by Pillarstone of all losses, claims, damages, liabilities, joint or several, expenses (including, without limitation, attorneys fees and other legal fees and expenses), judgments, fines, settlements and other amounts, arising from or in connection with any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, relating to Pillarstone OP or the General Partner or the operation of, or the ownership of property in which an indemnitee may be involved, or is threatened to be involved, unless a court of competent jurisdiction establishes that indemnification is not permitted under the circumstances described in the Pillarstone OP Amended and Restated Agreement of Limited Partnership.

These reimbursement provisions have provided us with critical sources of cash and liquidity to maintain our operations. Following Whitestone's abrupt termination of managerial services to Pillarstone OP, we have incurred significant costs to internalize management and to select and implement an enterprise-wide system of our own. We have also incurred substantial legal costs in our litigation with Whitestone.

We determined that Whitestone, under the property management agreements in effect until August 2022, was not making appropriate reimbursement of the General Partner's operating and administrative expenses from Pillarstone OP. During the first quarter of 2022, we recorded $1.8 million as reimbursement of expenses for the years ended 2017 through 2021. We recorded reimbursements from Pillarstone OP totaling $1.1 million in 2022 for operating and administrative expenses incurred in 2022. We recorded reimbursements from Pillarstone OP totaling $559 thousand and $271 thousand in the six months ended June 30, 2023 and 2022, respectively, for operating and administrative expenses incurred.

For financial reporting purposes, Pillarstone REIT and Pillarstone OP report on a consolidated basis, therefore, the reimbursement of our expenses does not change net income but only the allocations between controlling and noncontrolling interests.

*Whitestone Claim for Expenses.* After we notified Whitestone of the $1.8 million reimbursement required from Pillarstone OP, Whitestone and Whitestone OP made a claim to Pillarstone and Pillarstone OP to be reimbursed for construction and lease commission expenditures of $1.4 million paid by Whitestone OP on behalf of Pillarstone OP during 2017 and 2018. Pillarstone requested additional information for the $1.4 million expenditures to determine if any of the items claimed should have been prorated between Pillarstone OP and Whitestone OP in our transaction with Whitestone and Whitestone OP on December 8, 2016 for the initial acquisition of the Real Estate Assets. These expenditures were recorded on Pillarstone OP in 2017 and 2018 as an increase in the Whitestone OP limited partner investment account and as assets of Pillarstone OP that have been depreciated and amortized to expense over their useful lives. As of June 30, 2023, the amount due Whitestone OP for these expenditures, if any, had not been determined. If Pillarstone OP reimburses any amounts to Whitestone OP, the payment would reduce the Whitestone OP limited partner investment account. Whitestone's claims were settled pursuant to the settlement agreement described in Part II, Item 1, "Legal Proceedings—Jointly Administered Bankruptcy Cases."

*Indebtedness.* The Company's indebtedness at June 30, 2023 is presented in Item 1, "Financial Statements – Note 7 – Debt" and our lease obligations are presented in Item 1, "Financial Statements—Note 4 – Leases."

At June 30, 2023, Whitestone Uptown Tower, LLC, Pillarstone OP's subsidiary that owned the Uptown Tower office building, was the borrower under a loan agreement. The Uptown Tower office building was subject to a mortgage under the loan agreement. The mortgage debt was guaranteed by Whitestone OP. This mortgage was an obligation of Whitestone Uptown Tower, LLC, a subsidiary included in our consolidated financial statements. Neither Pillarstone Capital REIT nor Pillarstone OP had any obligation or guarantee of this indebtedness nor did any of our other properties collateralized this indebtedness.

------

As of June 30, 2023, the borrower was not in compliance with loan covenants requiring timely filing of financial information to the lender for mortgage loan.

In July 2023, Rialto Capital Advisors, LLC, the special servicer for the mortgage loan, implemented a cash sweep and began to seize the funds from the operations of the Uptown Tower property under the cash management agreement relating to the mortgage loan. Prior to Rialto Capital Advisors, LLC's seizing the funds from those operations, those funds had been used for the operation and maintenance of the Uptown Tower property, with excess funds used for the operations of Pillarstone OP and the General Partner. We did not have an alternate source of funds for the operation of Uptown Tower.

On August 3, 2023, we received a notice of the default of the mortgage loan from counsel for the lender and Rialto Capital Advisors, LLC. The default notice asserted non-monetary defaults resulting from Whitestone's failure to comply with the loan agreement in connection with the Contribution Agreement in 2016. The default notice also alleged a non-monetary default caused by Whitestone's termination of its management agreement for Uptown Tower in August 2022.

In the default notice, the lender and special servicer noted that the borrower, prior to the Contribution Agreement and while it was controlled by Whitestone OP, represented, warranted, and covenanted that "[F]following the Transfer, Sponsor [Whitestone REIT] through its ownership of Guarantor [Whitestone OP] [. . .] shall continue to Control Borrower [Whitestone Uptown Tower, LLC], and shall continue to control the day-to-day operation of the Property." The lender and special servicer contend that this representation was false because Pillarstone OP and the borrower are controlled by the general partner (Pillarstone Capital REIT, the sole general partner of Pillarstone OP) and not Whitestone REIT.

As the 2016 alleged defaults occurred while Whitestone was in control of all loan parties and we believe Whitestone caused the 2022 default through its unilateral termination of the management agreement for Uptown Tower, we are not in a position to agree with or dispute the determination of the alleged defaults or Whitestone OP's liability under its guaranty, or any further effect they may have on the borrower or the Uptown Tower property.

The borrower had requested disbursements of capital and operating expenditures from Rialto Capital Advisors, LLC under the terms of the loan agreement in August 2023 and September 2023, but Rialto Capital Advisors, LLC did not release the funds and indicated that it did not intend to release funds or reverse the cash sweep to permit the funding of the operations and leasing of Uptown Tower.

The mortgage loan matured on October 1, 2023. The registrant and the borrower had been working to extend the maturity date and to find new financing or a buyer for the Uptown Tower property. When Whitestone learned of our negotiations with Rialto Capital Advisors, LLC to attempt to resolve this issue and believing we were intending to abandon the building, it filed a motion with the Delaware Court of Chancery asking the court for an order declaring that we shall not (a) stop managing the Uptown Tower, (b) "hand the keys" to Uptown Tower to the lender, or (c) otherwise abandon the Uptown Tower, which the court granted on a temporary basis on September 22, 2023. On October 19, 2023, Whitestone objected to a proposed sale of the Uptown Tower property under the Status Quo Order issued by the court in the previously disclosed lawsuit Whitestone OP instituted against us in the Delaware Court of Chancery.

On October 24, 2023, the lender delivered a notice of foreclosure sale to the borrower providing notice that, among other things, as of the maturity date, the borrower failed to repay all amounts due under the note, and making a demand on (1) the borrower and all persons and entities obligated on the promissory note evidencing the mortgage loan (except to the extent that the obligation is expressly limited by written contract or applicable law) for payment in full of the entire indebtedness, and on (2) the borrower for payment of rents and proceeds of any rents to which the lender is entitled under the mortgage loan documents and Texas Property Code chapter 64, Assignment of Rents to Lienholder. The notice of foreclosure sale also included a notice regarding the planned foreclosure sale of Uptown Tower on December 5, 2023.

On December 1, 2023, Whitestone Uptown Tower, LLC filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Northern District of Texas. The filing of the petition constituted an event of default under the mortgage loan. Prior to the filing of the bankruptcy petition, representatives of our board of trustees attempted to initiate discussions with representatives of Whitestone REIT's board of trustees in November 2023 to address these matters and to approach Rialto Capital Advisors, LLC jointly. However, without the borrower's knowledge or consent, Whitestone attempted to pay off the loan and grant broad releases to the lender and special servicer on behalf of the borrower, including the application of the trapped cash, escrows and reserves to the indebtedness. No Whitestone REIT entity had the authority to make such agreements on behalf of the borrower, and we were informed that the agreement was not consummated but that Whitestone did send approximately $13.6 million to Rialto Capital Advisors, LLC pursuant to this arrangement.

On January 3, 2024, Rialto Capital Advisors, LLC provided a preliminary estimate of the payoff amounts for the Uptown Loan as of December 4, 2023. The estimated total amount due was listed as approximately $21.5 million, which included an outstanding principal balance of approximately $14.4 million, note interest of approximately $242,000 and default interest of approximately $6.6 million. In addition, Rialto was also holding approximately $2.6 million of trapped cash, escrows and reserves under the mortgage loan, which the borrower needed to operate the Uptown Tower property and pay its obligations, including then-upcoming property taxes. On January 31, 2024, the lender sued Whitestone OP to enforce Whitestone OP's guaranty of the mortgage loan.

------

In June 2024, Whitestone Uptown Tower, LLC and Whitestone OP each settled with the lender. Whitestone Uptown Tower entered into a loan agreement with American Bank, N.A. for a loan amount of up to $1,500,000, secured by Uptown Tower and all of the other assets of Whitestone Uptown Tower. Whitestone Uptown Tower paid approximately $1.1 million to the prior lender, and the prior lender retained approximately $2.2 million of trapped cash and escrows from the cash sweep and the approximately $13.6 million mistakenly sent to it by Whitestone OP in satisfaction of the prior mortgage loan.

The plan of reorganization in the bankruptcy case, providing for the sale of Uptown Tower and treatment of claims, was confirmed in July 2024. We sold Uptown Tower in July 2025 for a purchase price of $20 million, or $17.3 million after deductions, closing costs and commissions and paid off the American Bank, N.A. indebtedness. We distributed approximately $13.6 million of the sale proceeds to Whitestone OP, which represented funds Whitestone OP mistakenly paid to the prior mortgage lender for Uptown Tower when it attempted to pay off the mortgage loan without informing us and without authority to do so on Whitestone Uptown Tower, LLC's behalf. We are currently disputing the treatment and timing of repayment of the $13.6 million to Whitestone OP in the Whitestone Uptown Tower bankruptcy case.

In addition to the mortgage loan, we have approximately $198,000 of convertible notes payable and corresponding accrued interest of approximately $154,000 as of June 30, 2023. The convertible notes payable can be converted by the noteholders into Common Shares at the rate of $1.331 per Common Share at any time. At maturity or when the Company chooses to call the convertible notes payable, the noteholders have the option to receive cash plus accrued interest or convert the convertible notes payable into Common Shares at $1.331 per Common Share. The commencement of our bankruptcy case constituted an event of default under the notes, pursuant to which all principal and accrued interest became automatically and immediately due and payable. We repaid the convertible notes in January 2026.

At June 30, 2023, the reported net equity in Whitestone Uptown Tower, LLC was approximately $8.0 million.

*Long Term Liquidity and Operating Strategies.*

Our consolidated financial statements have been prepared assuming that we will continue as a going concern. We have incurred significant losses since the year ended December 31, 2020 and have an accumulated deficit of approximately $23.7 million as of June 30, 2023 and need to raise substantial amounts of additional funds to meet our obligations and afford us time to implement our business plan and resume profitable operations.

We worked diligently to restore normal operations and leasing activities following Whitestone's unanticipated termination of its managerial services. Many of Pillarstone's actions were affected by a lack of usable information being made available to us by Whitestone on a timely basis. Prior to receiving the termination notice, we had anticipated an orderly transition of the management of the Real Estate Assets over an appropriate timeframe, particularly as Whitestone OP owned 81.4% of Pillarstone OP as a non-controlling limited partner during the period covered by this report. We believe the management functions as operated by Whitestone were deeply integrated with Whitestone's management functions for its own business and have been difficult, expensive, and time-consuming to separate, causing material adverse effects on our business, income, cash flow, results of operations, financial condition, liquidity and prospects. As a result, Whitestone did significant damage to us by its intentional actions. In addition, our litigation with Whitestone has been and is expected to continue to be expensive, lengthy, and disruptive to normal business operations. Moreover, the results of these proceedings are difficult to predict. As a result, future adverse rulings, settlements, or unfavorable developments could result in charges that could have a material adverse effect on our business, results of operations or financial condition.

We were dependent on cash generated by our ownership of the eight Real Estate Assets to meet our liquidity needs. Following the period covered by this report, we have sold all of our Real Estate Assets pursuant to the plan of liquidation in the jointly administered bankruptcy cases and the Whitestone Uptown Tower plan of reorganization. Our debts have been repaid from the proceeds from the sales of our Real Estate Assets, including those of unsecured creditors subject to the Chapter 11 bankruptcy filings, which were repaid in December 2025 and January 2026.

Historically, we have financed our long-term capital needs, including acquisitions, as follows:

• borrowings from new loans;

• additional equity issuances of our common and preferred shares and operating partnership units; and

• proceeds from the sales of our Real Estate Assets.

------

In December 2025 over our objections, the bankruptcy court in the jointly administered bankruptcy cases issued an order approving an agreement between the plan agent and Whitestone REIT, Whitestone OP and Whitestone TRS settling the Whitestone claims in the jointly administered bankruptcy cases. The plan agent and Whitestone negotiated the settlement agreement without our participation. The bankruptcy court's order and the settlement agreement provided for, among other things:

• Allowed Claims (as defined in the plan of liquidation) of Whitestone Industrial-Office, LLC, Whitestone Offices, LLC and Whitestone CP Woodland Ph. 2, LLC (the "Subsidiary Debtors") shall be satisfied by payment in full from the Subsidiary Debtors. At the direction of the plan agent, the debtors shall make such payments to holders of Allowed Claims of the Subsidiary Debtors. After payment of the Allowed Claims of the Subsidiary Debtors, all remaining funds (the "Partnership Estate Funds") shall flow to the Pillarstone OP estate.

• the debtors shall use Partnership Estate Funds to establish the following three reserves to support the plan agent's claim administration process:

---

| | |
|:---|:---|
| o | the debtors shall use $1,000,000.00 of the Partnership Estate Funds to establish the "Partnership Tax Reserve". The plan agent shall direct the debtors to use the Partnership Tax Reserve to satisfy state and federal tax claims owed by Pillarstone OP and us. The debtors shall make such payments as directed by the plan agent; |

---

---

| | |
|:---|:---|
| o | the debtors shall use $1,000,000.00 of the Partnership Estate Funds to establish the "Case Administration Reserve". The plan agent shall direct the debtors to use the Cash Administration Reserve to fund estate administrative expenses including payment of estate employees, attorneys' fees, accounting fees, costs of administering claims, and winding up the estates of us, Pillarstone OP and the Subsidiary Debtors (together, the "Debtors Estates"). The debtors shall make such payments as directed by the plan agent; and |

---

---

| | |
|:---|:---|
| o | the debtors shall use $500,000.00 of the Partnership Estate Funds to establish the "Partnership GUC Reserve". The plan agent shall direct the debtors to use the Partnership GUC Reserve to satisfy all allowed general unsecured claims, including insider general unsecured claims, against Pillarstone OP. The debtors shall make such payments as directed by the plan agent. Should the debtors fail to make payment as directed, the plan agent shall seek relief from the Bankruptcy Court; |

---

• the debtors shall distribute $4,050,000.00 to the Pillarstone Capital REIT estate (the "Pillarstone Distribution") from the Partnership Estate Funds in satisfaction of all outstanding claims by us against the Pillarstone OP estate. The plan agent shall administer claims against our estate and shall direct the debtors to satisfy any allowed claims against our estate with the Pillarstone Distribution and any other cash in our estate. The plan agent shall direct the debtors to distribute any surplus proceeds remaining from the Pillarstone Distribution to our equity interest holders in accordance with the plan of liquidation in the jointly administered bankruptcy cases. This distribution was made in December 2025;

• following the satisfaction of all the claims of the Subsidiary Debtors, and of the reserves set forth above, the debtors shall distribute all funds remaining in the Pillarstone OP estate to Whitestone OP no later than December 12, 2025. This payment (the "WROP Distribution") was made in December 2025;

• the plan agent shall direct the debtors to distribute any surplus funds from the Partnership Tax Reserve, Case Administrative Reserve, and Partnership Tax Reserve remaining after the complete administration of the Debtors' Estates to Whitestone OP. The debtors shall make such Surplus Reserve Funds payments as directed by the plan agent;

• upon entry of the final order approving the motion to approve the settlement, the plan agent and Whitestone OP shall promptly move to dismiss with prejudice:

---

| | |
|:---|:---|
| o | the adversary proceeding commenced by Pillarstone OP in the jointly administered bankruptcy cases; |

---

---

| | |
|:---|:---|
| o | the Houston litigation discussed in Part II, Item 1 "Legal Proceedings—Houston Case"; and |

---

---

| | |
|:---|:---|
| o | the Delaware litigation discussed in Part II, Item 1 "Legal Proceedings —Delaware Case"; |

---

• upon entry of the final order, and payment of the WROP Distribution, Whitestone OP shall (a) move to dismiss with prejudice all pending litigation initiated by it against any of the debtors, and (b) withdraw its proof of claim against Pillarstone OP in the amount of $52,963,904.83 and its proof of claim against Pillarstone Capital REIT in the amount of $9,966,778.64;

• the plan agent, on behalf of the debtors and the Debtors Estates, granted a release to Whitestone REIT, Whitestone OP, Whitestone TRS and certain of their related parties and agreed to ensure the dismissal with prejudice of all pending claims, causes of action and lawsuits brought by any of the debtors against such parties. The Whitestone parties granted releases to the plan agent and the Debtors Estates and agreed to ensure the dismissal with prejudice of all pending claims, causes of actions and lawsuits against any of the debtors, including the Delaware litigation. Whitestone OP agreed to dismiss its claims and causes of action against James C. Mastandrea pending in his adversary claims in the jointly administered bankruptcy cases to the extent he is seeking indemnification against the Debtors Estates on account of those claims; and

------

• the bankruptcy court shall retain exclusive personal and subject matter jurisdiction to enforce the terms of the settlement agreement and to decide any claims or disputes that may arise or result from, or be connected with, the settlement agreement, or any breach or default thereunder.

Whitestone Uptown Tower, LLC was not party or subject to the settlement, and the litigation in its bankruptcy case was not resolved under the settlement.

To implement our business strategy, additional capital will need to be raised. Our ability to access the capital markets will be dependent on a number of factors, including general market conditions and market perceptions about our Company. There can be no assurance that we will be able to raise capital, obtain debt financing, or improve operating results sufficiently to continue as a going concern, if at all. The consolidated financial statements included in this report do not include any adjustments that might result from the outcome of this uncertainty.

**Interest Rates and Inflation**

We were not significantly affected by rising interest rates during the periods presented in this report due primarily to having 100% of our debt with a fixed rate as of June 30, 2023. Any new indebtedness may be at higher rates than the 4.97% base rate of interest under the loan agreement, plus the default rate of interest, which is 5% above the interest rate under the loan agreement. For example, the mortgage loan with American Bank, N.A. that replaced the prior loan for Uptown Tower bears interest at the WSJ Prime Rate (as defined in the loan agreement) plus 7.5%. If we are not able to incur indebtedness on favorable terms to us, our business, financial condition, results of operations, or cash flows could be materially adversely affected.

We anticipate that the majority of our leases will continue to be triple-net leases or otherwise provide that tenants pay for increases in operating expenses and will contain provisions that we believe will mitigate the effect of inflation. In addition, many of our leases are for terms of less than five years, which allows us to adjust rental rates to reflect inflation and other changing market conditions when the leases expire. Leases of longer-term durations or which include renewal options that specify a maximum rate increase may result in below-market lease rates over time if we do not accurately estimate inflation or market lease rates. Provisions of our leases designed to mitigate the risk of inflation and unexpected increases in market lease rates, such as periodic rental increases, may not adequately protect us from the impact of inflation or unexpected increases in market lease rates. If we are subject to below-market lease rates on a significant number of our properties pursuant to long-term leases and our operating and other expenses increase faster than anticipated, our business, financial condition, results of operations, or cash flows could be materially adversely affected.

**Off-Balance Sheet Arrangements** 

We have no off-balance sheet arrangements that have, or are likely to have, a current or future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

**Critical Accounting Estimates**

Our consolidated financial statements are prepared in accordance with GAAP, which require us to make certain estimates and assumptions. The following section is a summary of certain estimates that both require our most subjective judgment and are most important to the presentation of our financial condition and results of operations. It is possible that the use of different estimates or assumptions in making these judgments could result in materially different amounts being reported in our consolidated financial statements.

*Revenue recognition*. All leases on our properties are classified as noncancelable operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases. Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to accrued rents and accounts receivable. Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the period the corresponding costs are incurred. We combine lease and non-lease components in lease contracts, which includes combining base rent and recoveries into a single line item, Rental, within the consolidated statements of operations. We recognize lease termination fees in the year that the lease is terminated, and collection of the fee is reasonably assured.

*Impairment.* We review our properties for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations. We determine whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property. If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. There was no impairment of our Real Estate Assets during the periods presented in this report.

------

*Accrued Rents and Accounts Receivable.* Included in accrued rent and accounts receivable are base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. We review the collectability of charges under our tenant operating leases on a regular basis, taking into consideration changes in factors such as the tenant's payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. We recognize an adjustment to rental revenue if we deem it probable that the receivable will not be collected. Our review of collectability under our operating leases includes any accrued rental revenues related to the straight-line method of reporting rental revenue.

*Income taxes*. We have not elected to be taxed as a REIT for federal income tax purposes. As such, we account for income taxes using the asset and liability method under which deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the period in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We are also subject to certain state and local income, excise and franchise taxes. The provision for state and local taxes has been reflected in the provision for income taxes in the consolidated statements of operations and has not been separately stated due to its insignificance.

**ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

Not applicable.

**ITEM 4. CONTROLS AND PROCEDURES**

**Evaluation of Disclosure Controls and Procedures**

Our management, under the supervision and with the participation of our principal executive and financial officers, has evaluated the effectiveness of our disclosure controls and procedures, as such term is defined in Rules 13a 15(e) and 15d 15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act") in ensuring that the information required to be disclosed in our filings under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, including ensuring that such information is accumulated and communicated to management to allow timely decisions regarding required disclosure.

Based on such evaluation, our principal executive and financial officers have concluded at a reasonable assurance level that such disclosure controls and procedures were not effective as of June 30, 2023.

**Management**'**s Report on Internal Control Over Financial Reporting**

In connection with the preparation of our consolidated financial statements, management assessed the effectiveness of our internal control over financial reporting as of June 30, 2023, based on criteria established in the *Internal Control-Integrated Framework (2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission (the "COSO criteria").

Based on this assessment, the following material weaknesses have been identified:

● we did not design and implement logical access controls for certain financially relevant systems. Business processes, both automated and manual, that are dependent upon the information derived from those financially relevant systems were also determined to be ineffective as a result of such deficiency; and

● business process controls across our financial reporting processes were not effectively designed and implemented to properly address the risk of material misstatement, including controls without proper segregation of duties between preparer and reviewer and key management review controls.

Management has concluded that, based on applying the COSO criteria, as of June 30, 2023, our internal control over financial reporting was not effective to provide reasonable assurance of the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles.

*Remediation Plans.* These material weaknesses arose because of Whitestone's abrupt termination in August 2022 of managerial services they provided. At the date its managerial services ceased, we did not have our own personnel, processes or systems needed for proper accounting and financial reporting. While we immediately began to address these needs after Whitestone's termination, we were unable to complete the design and implementation of appropriate internal control over financial reporting before year-end. These material weaknesses did not result in a material misstatement of our consolidated financial statements for the periods presented.

We have been working diligently on the process of designing and implementing effective internal control measures to remediate the reported material weaknesses. Our efforts include implementing a new enterprise-wide system that will help us in reducing reliance on manual processes and spreadsheets supporting the financial statements. This implementation was completed in 2023. We are using contract personnel for specialized accounting and financial reporting roles.

------

While we believe that these efforts will improve our internal control over financial reporting, our remediation efforts are ongoing and will require validation and testing of the design and operating effectiveness of internal controls. The actions that we are taking are subject to ongoing senior management review, as well as audit committee oversight. We will not be able to conclude whether the steps we are taking will fully remediate the remaining material weakness in our internal control over financial reporting until we have completed our remediation efforts and subsequent evaluation of their effectiveness. We may also conclude that additional measures may be required to remediate the material weakness in our internal control over financial reporting.

**Changes in Internal Control Over Financial Reporting**

We are taking actions to remediate the material weakness relating to our internal control over financial reporting, as described above. Our efforts to internalize management, establish new accounting and financial reporting processes and implement new systems have resulted in changes to our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Except as otherwise described herein, there were no changes in our internal control over financial reporting that occurred during the three months ended June 30, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**PART II. OTHER INFORMATION**

**ITEM 1. LEGAL PROCEEDINGS**

We may from time to time become a party to legal proceedings and claims that arise in the ordinary course of our business. These matters are generally covered by insurance. While the frequency and resolutions of any ordinary course matters cannot be predicted with certainty, we believe that occurrence and outcomes of these ordinary course matters will not have a material effect on our financial position, results of operations or cash flows. Other legal matters are discussed below.

**Delaware Case**

On July 12, 2022, we were named as a defendant in a lawsuit by Whitestone OP in a lawsuit styled *Whitestone REIT Operating Partnership, L.P. v. Pillarstone Capital REIT,* C.A. No. 2022-0607-LWW, in the Court of Chancery of the State of Delaware. The suit challenged our rights agreement, dated as of December 27, 2021 (as the same may be amended from time to time, the "Rights Agreement"), between us and American Stock Transfer & Trust Company, LLC, as rights agent, and claimed that our adoption of the Rights Agreement breached the Pillarstone OP Amended and Restated Agreement of Limited Partnership, and that we breached our fiduciary duties as general partner of Pillarstone OP to Whitestone OP and breached the implied covenant of good faith and fair dealing under the Amended and Restated Agreement of Limited Partnership.

Based upon various issues, including those discussed in this report, we filed a lawsuit on September 16, 2022, in district court in Harris County, Texas, against Whitestone and related parties alleging, among other things, breach of the Pillarstone OP Amended and Restated Agreement of Limited Partnership and fiduciary duty and breach of the management agreements.

On July 21, 2022, Whitestone OP filed a Motion to Preserve the Status Quo in the Delaware lawsuit requesting broad restrictions on our ability to conduct our business, including buying properties, enforcing the Rights Agreement, incurring expenses, or engaging in transactions. The Status Quo Order also prevented Whitestone OP from exercising its right under the Pillarstone OP Amended and Restated Agreement of Limited Partnership to require Pillarstone OP to redeem its OP Units. Our amended petition in the Texas lawsuit argued that Whitestone's material breaches of contract and fiduciary duty operated to discharge and/or excuse any obligation to perform under the redemption provisions of the Pillarstone OP Amended and Restated Agreement of Limited Partnership.

Representatives of our board of trustees attempted to initiate discussions to settle these matters in August 2022 with representatives of Whitestone's board of trustees to avoid a prolonged, expensive legal fight. However, Whitestone was not open to settling these matters at that time or the other various times since August 2022 we attempted to initiate discussions to resolve these matters.

Whitestone indicated to us its intent to cause Whitestone OP to exercise its redemption right and stated publicly that it intended to monetize its investment in Pillarstone OP. We believed that if Whitestone were to be permitted to exercise its redemption right for cash amounts, we may not have the cash available to pay such amounts and may be required to sell one or more of our Real Estate Assets to satisfy this obligation, which may cause us to sell some or all of our Real Estate Assets at below fair market value and otherwise have a material adverse effect on our liquidity and financial condition and our ability to operate and improve our Real Estate Assets. We stated that a redemption request would not trigger the Rights Agreement, and our board of trustees had the sole discretion to interpret the Rights Agreement. However, Whitestone OP indicated that the Rights Agreement caused them to not exercise their redemption rights and claimed damages based on the alleged decline in the value of the Real Estate Assets following their failure to exercise the redemption rights.

Based on Whitestone's performance under the management agreements and their public statements regarding their intentions for their interest in Pillarstone, we did not believe that Whitestone's actions in connection with the exercise of the redemption rights would respect the rights of the holders of our common shares. The Pillarstone OP Amended and Restated Agreement of Limited Partnership expressly provides that in the event of a conflict between the interests of the limited partners (Whitestone OP as the sole limited partner) and our shareholders, we shall act in the interests of our shareholders, and we shall not be liable for monetary or other losses sustained, liabilities incurred or benefits not derived by the limited partners in connection therewith.

------

Our executive management team worked to restore normal operations and leasing activities quickly after Whitestone's unanticipated termination of their managerial services. Many of our actions were affected by a lack of usable information being made available to us on a timely basis.

We discovered significant deferred maintenance and neglect of our assets had occurred under Whitestone's management. Our efforts to address these matters were in some cases stymied by Whitestone's litigation against us in Delaware where the court limited our ability to incur expenses above low threshold amounts for the types of expenses a company in our industry could expect to incur in the ordinary course of business. Our legal and professional fees increased substantially as we addressed the internalization of management and the litigation matters discussed in this report.

On July 17, 2023 and July 18, 2023, trial was held in the Delaware lawsuit. Post-trial argument in the lawsuit was held on October 18, 2023. Whitestone has asked the Delaware court to award damages of approximately $51,200,600 and post-judgement interest of $6,820,000 in the filing of its post-trial opening brief on August 28, 2023. On January 25, 2024, the Delaware court issued its opinion and determined that we breached the implied covenant of good faith and fair dealing without resolving the breach of contract or breach of fiduciary duty claims. Although Whitestone asked for monetary damages of $51,200,600 plus interest, the Delaware court declined to award damages.

The Delaware court declared the Rights Agreement unenforceable against Whitestone, permitted Whitestone OP to tender a notice of redemption for its OP Units and determined that the Pillarstone OP limited partnership agreement should be followed whereby we would decide whether to assume Pillarstone OP's redemption obligation and determine what value to attribute to Pillarstone OP's assets. The Delaware court declared that any further relief must await future proceedings.

On January 25, 2024, Whitestone OP delivered its notice of redemption for all but one of its OP Units.

This case was settled pursuant to the settlement agreement described in "—Jointly Administered Bankruptcy Cases" below.

**Houston Case**

On September 16, 2022, we filed a lawsuit styled *Pillarstone Capital REIT and Pillarstone Capital REIT Operating Partnership LP v. Whitestone TRS, Inc., Whitestone REIT, Whitestone REIT Operating Partnership, L.P.,* Cause No. 2022-59478, in the District Court, Harris County, Texas, 189th Judicial District alleging, among other things, breach of the Pillarstone OP limited partnership agreement and the management agreements for the Real Estate Assets by the Whitestone defendants and breach of fiduciary duties relating to Pillarstone OP by Whitestone OP going outside the role of limited partner and harming us and Pillarstone OP. A portion of the claims in this case were moved into an adversary proceeding by Whitestone Uptown Tower, LLC in the Uptown Tower bankruptcy case described in "—Uptown Tower" below, and the other claims were settled pursuant to the settlement agreement described in "—Jointly Administered Bankruptcy Cases" below.

**Jointly Administered Bankruptcy Cases**

On March 4, 2024, bankruptcy cases were filed for us and Pillarstone OP, as well as Whitestone CP Woodland Ph. 2, LLC, Whitestone Industrial-Office, LLC and Whitestone Offices, LLC, the subsidiaries owning our Real Estate Assets other than Uptown Tower. The bankruptcy cases were consolidated into the jointly administered bankruptcy cases styled *In re: Whitestone Industrial-Office, LLC, et. al.*, Case No. 24-30653-mvl-11, in the United States Bankruptcy Court for the Northern District of Texas, Dallas Division, the same court as, but separate cases from, the Whitestone Uptown Tower, LLC bankruptcy case described under "—Uptown Tower" below.

The plan of liquidation in the jointly administered bankruptcy cases providing for the sale of the Real Estate Assets other than Uptown Tower and treatment of claims was confirmed in November 2024. Those Real Estate Assets were sold between October 2024 and July 2025.

The plan provided for a plan agent, and Frances A. Smith was appointed plan agent in the jointly administered bankruptcy cases. The plan agent was appointed for the purposes of administering all claims in the bankruptcy cases and making distributions to holders of allowed claims and equity interests under the plan of liquidation. The plan agent's administration of the claims may include, without limitation, and pursuant to her reasonable business judgment, investigating, prosecuting, objecting to, resolving, reconciling, compromising, litigating, administering, and making distributions on account of, the claims.

The plan agent is not a trustee and does not participate in the management or operations of the debtors' businesses, assets or financial affairs or the review and approval of the day-to-day operational expenses of the debtors' business post-confirmation, unless the bankruptcy court determines cause exists for the plan agent to do so after notice and hearing.

------

The plan agent has the sole and exclusive authority to administer the claims, including the determination to compromise a claim involving Whitestone OP, any debtor or their affiliates or professionals, subject to notice and hearing and a party's good-faith objection and the bankruptcy court's final adjudication of the matter. The plan agent also has the authority to make demand on the debtors for funds necessary to satisfy allowed claims asserted against a debtor from that debtor's funds (even if held by Pillarstone OP), which may include sales proceeds.

The plan agent is entitled to receive compensation as a flat fee of $10,000 per month, plus reimbursement of actual, necessary expenses. If during any month the plan agent spends more than fifteen (15) hours in the performance of her duties, she will be entitled to compensation at a rate of $650 per hour for each additional hour of services.

In December 2025 over our objections, the bankruptcy court issued an order approving an agreement between the plan agent and Whitestone REIT, Whitestone OP and Whitestone TRS settling the Whitestone claims in the jointly administered bankruptcy cases. The plan agent and Whitestone negotiated the settlement agreement without our participation. The bankruptcy court's order and the settlement agreement provided for, among other things:

● Allowed Claims (as defined in the plan of liquidation) of Whitestone Industrial-Office, LLC, Whitestone Offices, LLC and Whitestone CP Woodland Ph. 2, LLC (the "Subsidiary Debtors") shall be satisfied by payment in full from the Subsidiary Debtors. At the direction of the plan agent, the debtors shall make such payments to holders of Allowed Claims of the Subsidiary Debtors. After payment of the Allowed Claims of the Subsidiary Debtors, all remaining funds (the "<u>Partnership Estate Funds</u>") shall flow to the Pillarstone OP estate.

● the debtors shall use Partnership Estate Funds to establish the following three reserves to support the plan agent's claim administration process:

---

| | |
|:---|:---|
| o | the debtors shall use $1,000,000.00 of the Partnership Estate Funds to establish the "Partnership Tax Reserve". The plan agent shall direct the debtors to use the Partnership Tax Reserve to satisfy state and federal tax claims owed by Pillarstone OP and us. The debtors shall make such payments as directed by the plan agent; |

---

---

| | |
|:---|:---|
| o | the debtors shall use $1,000,000.00 of the Partnership Estate Funds to establish the "Case Administration Reserve". The plan agent shall direct the debtors to use the Cash Administration Reserve to fund estate administrative expenses including payment of estate employees, attorneys' fees, accounting fees, costs of administering claims, and winding up the estates of us, Pillarstone OP and the Subsidiary Debtors (together, the "Debtors Estates"). The debtors shall make such payments as directed by the plan agent; and |

---

---

| | |
|:---|:---|
| o | the debtors shall use $500,000.00 of the Partnership Estate Funds to establish the "Partnership GUC Reserve". The plan agent shall direct the debtors to use the Partnership GUC Reserve to satisfy all allowed general unsecured claims, including insider general unsecured claims, against Pillarstone OP. The debtors shall make such payments as directed by the plan agent. Should the debtors fail to make payment as directed, the plan agent shall seek relief from the Bankruptcy Court; |

---

● the debtors shall distribute $4,050,000.00 to the Pillarstone Capital REIT estate (the "Pillarstone Distribution") from the Partnership Estate Funds in satisfaction of all outstanding claims by us against the Pillarstone OP estate. The plan agent shall administer claims against our estate and shall direct the debtors to satisfy any allowed claims against our estate with the Pillarstone Distribution and any other cash in our estate. The plan agent shall direct the debtors to distribute any surplus proceeds remaining from the Pillarstone Distribution to our equity interest holders in accordance with the plan of liquidation in the jointly administered bankruptcy cases. This distribution was made in December 2025;

● following the satisfaction of all the claims of the Subsidiary Debtors, and of the reserves set forth above, the debtors shall distribute all funds remaining in the Pillarstone OP estate to Whitestone OP no later than December 12, 2025. This payment (the "WROP Distribution") was made in December 2025;

● the plan agent shall direct the debtors to distribute any surplus funds from the Partnership Tax Reserve, Case Administrative Reserve, and Partnership Tax Reserve remaining after the complete administration of the Debtors' Estates to Whitestone OP. The debtors shall make such Surplus Reserve Funds payments as directed by the plan agent;

● upon entry of the final order approving the motion to approve the settlement, the plan agent and Whitestone OP shall promptly move to dismiss with prejudice:

---

| | |
|:---|:---|
| o | the adversary proceeding commenced by Pillarstone OP in the jointly administered bankruptcy cases; |

---

---

| | |
|:---|:---|
| o | the Houston litigation discussed in "—Houston Case" above; and |

---

---

| | |
|:---|:---|
| o | the Delaware litigation discussed in "—Delaware Case" above; |

---

------

● upon entry of the final order, and payment of the WROP Distribution, Whitestone OP shall (a) move to dismiss with prejudice all pending litigation initiated by it against any of the debtors, and (b) withdraw its proof of claim against Pillarstone OP in the amount of $52,963,904.83 and its proof of claim against Pillarstone Capital REIT in the amount of $9,966,778.64;

● the plan agent, on behalf of the debtors and the Debtors Estates, granted a release to Whitestone REIT, Whitestone OP, Whitestone TRS and certain of their related parties and agreed to ensure the dismissal with prejudice of all pending claims, causes of action and lawsuits brought by any of the debtors against such parties. The Whitestone parties granted releases to the plan agent and the Debtors Estates and agreed to ensure the dismissal with prejudice of all pending claims, causes of actions and lawsuits against any of the debtors, including the Delaware litigation. Whitestone OP agreed to dismiss its claims and causes of action against James C. Mastandrea pending in his adversary claims in the jointly administered bankruptcy cases to the extent he is seeking indemnification against the Debtors Estates on account of those claims; and

● the bankruptcy court shall retain exclusive personal and subject matter jurisdiction to enforce the terms of the settlement agreement and to decide any claims or disputes that may arise or result from, or be connected with, the settlement agreement, or any breach or default thereunder.

Whitestone Uptown Tower, LLC was not party or subject to the settlement, and the litigation in its bankruptcy case was not resolved under the settlement.

**Uptown Tower**

Whitestone Uptown Tower, LLC, Pillarstone OP's subsidiary that owned the Uptown Tower office building, was the borrower under a loan agreement. The Uptown Tower office building was subject to a mortgage under the loan agreement. The mortgage debt was guaranteed by Whitestone OP. This mortgage was an obligation of Whitestone Uptown Tower, LLC, a subsidiary included in our consolidated financial statements until its deconsolidation in December 2023. Neither Pillarstone Capital REIT nor Pillarstone OP had any obligation or guarantee of this indebtedness nor did any of our other properties collateralize this indebtedness.

As of June 30, 2023, the borrower was not in compliance with loan covenants requiring timely filing of financial information to the lender for the mortgage loan. In addition, the lender asserted that Whitestone's termination of the management agreement for Uptown Tower also caused an event of default under the loan agreement.

In July 2023, Rialto Capital Advisors, LLC, the special servicer for the mortgage loan, implemented a cash sweep and began to seize the funds from the operations of the Uptown Tower property under the cash management agreement relating to the mortgage loan. Prior to Rialto Capital Advisors, LLC's seizing the funds from those operations, those funds had been used for the operation and maintenance of the Uptown Tower property, with excess funds used for the operations of Pillarstone OP and the General Partner. We did not have an alternate source of funds for the operation of Uptown Tower.

On August 3, 2023, we received a notice of the default of the mortgage loan from counsel for the lender and Rialto Capital Advisors, LLC. The default notice asserted non-monetary defaults resulting from Whitestone's failure to comply with the loan agreement in connection with the Contribution Agreement in 2016. The default notice also alleged a non-monetary default caused by Whitestone's termination of its management agreement for Uptown Tower in August 2022.

In the default notice, the lender and special servicer noted that the borrower, prior to the Contribution Agreement and while it was controlled by Whitestone OP, represented, warranted, and covenanted that "[F]ollowing the Transfer, Sponsor [Whitestone REIT] through its ownership of Guarantor [Whitestone OP] [. . .] shall continue to Control Borrower [Whitestone Uptown Tower, LLC], and shall continue to control the day-to-day operation of the Property." The lender and special servicer contend that this representation was false because Pillarstone OP and the borrower are controlled by the general partner (Pillarstone Capital REIT, the sole general partner of Pillarstone OP) and not Whitestone REIT.

As the 2016 alleged defaults occurred while Whitestone was in control of all loan parties and we believe Whitestone caused the 2022 default through its unilateral termination of the management agreement for Uptown Tower, we are not in a position to agree with or dispute the determination of the alleged defaults or Whitestone OP's liability under its guaranty, or any further effect they may have on the borrower or the Uptown Tower property.

The borrower requested disbursements of capital and operating expenditures from Rialto Capital Advisors, LLC under the terms of the loan agreement in August 2023 and September 2023, but Rialto Capital Advisors, LLC did not release the funds and indicated that it did not intend to release funds or reverse the cash sweep to permit the funding of the operations and leasing of Uptown Tower.

The mortgage loan matured on October 1, 2023. The registrant and the borrower had been working to extend the maturity date and to find new financing or a buyer for the Uptown Tower property. When Whitestone learned of our negotiations with Rialto Capital Advisors, LLC to attempt to resolve this issue and believing we were intending to abandon the building, it filed a motion with the Delaware Court of Chancery asking the court for an order declaring that we shall not (a) stop managing the Uptown Tower, (b) "hand the keys" to Uptown Tower to the lender, or (c) otherwise abandon the Uptown Tower, which the court granted on a temporary basis on September 22, 2023. On October 19, 2023, Whitestone objected to a proposed sale of the Uptown Tower property under the Status Quo Order issued by the court in the previously disclosed lawsuit Whitestone OP instituted against us in the Delaware Court of Chancery.

------

On October 24, 2023, the lender delivered a notice of foreclosure sale to the borrower providing notice that, among other things, as of the maturity date, the borrower failed to repay all amounts due under the note, and making a demand on (1) the borrower and all persons and entities obligated on the promissory note evidencing the mortgage loan (except to the extent that the obligation is expressly limited by written contract or applicable law) for payment in full of the entire indebtedness, and on (2) the borrower for payment of rents and proceeds of any rents to which the lender is entitled under the mortgage loan documents and Texas Property Code chapter 64, Assignment of Rents to Lienholder. The notice of foreclosure sale also included a notice of foreclosure sale regarding the planned foreclosure sale of Uptown Tower on December 5, 2023.

On December 1, 2023, Whitestone Uptown Tower, LLC filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Northern District of Texas in the case styled *In re: Whitestone Uptown Tower, LLC a/a/ Pillarstone Capital REIT Operating Partnership*, Case No. 23-32832-mvl-11, in the United States Bankruptcy Court for the Northern District of Texas, Dallas Division. The filing of the petition constituted an event of default under the mortgage loan. Prior to the filing of the bankruptcy petition, in November 2023, representatives of our board of trustees attempted to initiate discussions with representatives of Whitestone REIT's board of trustees to address these matters and to approach Rialto Capital Advisors, LLC jointly. However, without the borrower's knowledge or consent, Whitestone attempted to pay off the loan and grant broad releases to the lender and special servicer on behalf of the borrower, including the application of the trapped cash, escrows and reserves to the indebtedness. No Whitestone REIT entity had the authority to make such agreements on behalf of the borrower, and we were informed that the agreement was not consummated, but Whitestone did send approximately $13.6 million to Rialto Capital Advisors, LLC pursuant to this arrangement.

On January 3, 2024, Rialto Capital Advisors, LLC provided a preliminary estimate of the payoff amounts for the Uptown Loan as of December 4, 2023. The estimated total amount due was listed as approximately $21.5 million, which included an outstanding principal balance of approximately $14.4 million, note interest of approximately $242,000 and default interest of approximately $6.6 million. In addition, Rialto was also holding approximately $2.6 million of trapped cash, escrows and reserves under the mortgage loan, which the borrower needed to operate the Uptown Tower property and pay its obligations, including then-upcoming property taxes. On January 31, 2024, the lender sued Whitestone OP to enforce Whitestone OP's guaranty of the mortgage loan.

In June 2024, Whitestone Uptown Tower, LLC and Whitestone OP each settled with the lender. Whitestone Uptown Tower entered into a loan agreement with American Bank, N.A. for a loan amount of up to $1,500,000, secured by Uptown Tower and all of the other assets of Whitestone Uptown Tower. Whitestone Uptown Tower paid approximately $1.1 million to the prior lender, and the prior lender retained approximately $2.2 million of trapped cash and escrows from the cash sweep and the approximately $13.6 million mistakenly sent to it by Whitestone OP in satisfaction of the prior mortgage loan.

The plan of reorganization in the bankruptcy case, providing for the sale of Uptown Tower and treatment of claims, was confirmed in July 2024. We sold Uptown Tower in July 2025 for a purchase price of $20 million, or $17.3 million after deductions, closing costs and commissions and reimbursements to the seller, and paid off the American Bank, N.A. indebtedness.

Over the objection of Whitestone Uptown Tower, LLC, the bankruptcy ruled in favor of Whitestone OP that it was statutorily subrogated to the secured claim of the lender of the mortgage loan with respect to its mistaken payment to the mortgage loan lender. We paid $13.6 million of the Uptown Tower sale proceeds to Whitestone OP representing funds it had mistakenly paid to the prior mortgage lender for Uptown Tower when it attempted to pay off the mortgage loan without informing us and without authority to do so. On October 25, 2024, Whitestone Uptown Tower, LLC also appealed that ruling in the United States District Court for the Norther District of Texas, Dallas Division, in the case styled *Whitestone Uptown Tower, LLC v. Whitestone REIT Operating Partnership, L.P.*, Case No. 24-02699. The District Court affirmed the bankruptcy court ruling, and Whitestone Uptown Tower, LLC appealed the District Court's ruling to the United States Court of Appeals for the Fifth Circuit on August 13, 2025. The appeal is ongoing as of the date of this report.

On June 4, 2025, Whitestone Uptown Tower filed an adversary proceeding in its bankruptcy case styled *Whitestone Uptown Tower, LLC v. Whitestone REIT, Whitestone REIT Operating Partnership L.P. and Whitestone TRS, Inc.,* Adv. Proc No. 25-03061, in the United States Bankruptcy Court for the Northern District of Texas, Dallas Division for breach of contract and breach of fiduciary duties related to the management of Uptown Tower under the management agreements as discussed under "—Houston Case" above. This case remains ongoing as of the date of this report.

The Uptown Tower bankruptcy proceedings have been and are expected to continue to be expensive, lengthy, and disruptive to normal business operations. Moreover, the results of these proceedings are difficult to predict. In addition, we intend to vigorously pursue the Uptown Tower action to seek damages from Whitestone due to its violations of the management agreements and fiduciary duties and to protect our shareholders. However, the outcomes of these proceedings, including the timing of the final disposition of the proceedings, are unpredictable and could result in substantial costs to us and affect our ability to recover funds from Whitestone Uptown Tower, LLC. As a result, future adverse rulings, settlements, or unfavorable developments could result in a material adverse effect on the registrant's business, results of operations or financial condition.

**Issuance of Convertible Notes to Trustees**

In November 2015, five trustees serving on the Board of Pillarstone Capital at that time loaned funds to us, each pursuant to a Convertible Note Purchase Agreement (the "Agreement"). Pursuant to an Assignment and Assumption Agreement dated as of March 29, 2019 by and between Dennis Chookaszian Revocable Trust ("Mr. Chookaszian") and a former trustee, and a Stock Purchase Agreement dated as of March 29, 2019 by and between Mr. Chookaszian and the same former trustee, Mr. Chookaszian acquired the Agreement and assumed the rights under the Note. Another former trustee, Mr. DeVos, was a trustee in November 2015 but did not stand for re-election in 2019 and continues to own his note payable as shown in the schedule below.

The following individuals loaned the following face amounts that accrue interest at 10% per annum, which can be converted into common shares of Pillarstone Capital as of June 30, 2023, as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Trustee** | **Face Amount** | **Accrued**<br> **Interest** | **Convertible**<br> **into common**<br> **shares** |
| Dennis H. Chookaszian | $28888 | $22002 | 38234 |
| Daniel G. DeVos | $47780 | $36391 | 63239 |
| Paul T. Lambert | $51112 | $38929 | 67649 |
| James C. Mastandrea | $52224 | $39776 | 69121 |
| John J. Dee | $17776 | $13539 | 23527 |
| **Totals** | $**197780** | $**150637** | **261770** |

---

The convertible notes can be called by us after six months, at which time the noteholder can choose to receive either the amount of the note plus any accrued but unpaid interest or the number of common shares determined by dividing the amount of the note plus any accrued but unpaid interest by the conversion price of $1.331. The noteholder has the option at any time to convert the note plus any accrued but unpaid interest into common shares based on the conversion price of $1.331.

------

The convertible notes were issued effective November 20, 2015, had a maturity date of three years and had been extended multiple times. The commencement of our bankruptcy case constituted an event of default under the notes, pursuant to which all principal and accrued interest became automatically and immediately due and payable. We repaid the convertible notes pursuant to our plan of liquidation and bankruptcy court proceedings in January 2026 in the following amounts:

---

| | |
|:---|:---|
| **Trustee** | **Amount** |
| Dennis H. Chookaszian | $52845.25 |
| Daniel G. DeVos | $87404.67 |
| Paul T. Lambert | $93499.95 |
| James C. Mastandrea | $95534.15 |
