This Annual Report on Form 10-K contains forward-looking statements within the meaning of the federal securities laws, including discussion and analysis of our financial condition, anticipated capital expenditures required to complete projects, amounts of anticipated cash distributions to our shareholders in the future and other matters. These forward-looking statements are not historical facts but are the intent, belief or current expectations of our management based on its knowledge and understanding of our business and industry. Forward-looking statements are typically identified by the use of terms such as “may,” “will,” “should,” “potential,” “predicts,” “anticipates,” “expects,” “intends,” “plans,” “believes,” “seeks,” “estimates” or the negative of such terms and variations of these words and similar expressions, although not all forward-looking statements include these words. These statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond our control, are difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements.

Forward-looking statements that were true at the time made may ultimately prove to be incorrect or false. You are cautioned not to place undue reliance on forward-looking statements, which reflect our management’s view only as of the date of this Annual Report on Form 10-K.

Item 1. Business.

Company Overview

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. As of December 31, ~~2022~~2023, the Company, through the limited partnership of which the Company is general partner, owned six properties in Houston, Texas and two properties in Dallas, Texas. Future real estate investments may include (i) acquisition and development of retail, office, office warehouse, industrial, multifamily, hotel, and other commercial properties, (ii) acquisition of or merger with a REIT or a real estate operating company and (iii) joint venture investments. Excess funds can be invested in cash equivalents depending on market conditions.

The Company was formed on March 15, 1994 as a Maryland REIT. The Company operated as a traditional REIT by buying, selling, owning and operating commercial and residential properties through December 31, 1999. In 2000, the Company purchased a software technology company, resulting in the Company no longer meeting qualifications to be a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). In 2002, the Company discontinued the operations of the technology segment.

From 2003 through 2006, we 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. In 2006, the Company did not complete a public offering for a portfolio acquisition due to market conditions, and consequently, was not able to meet the listing requirements of the former American Stock Exchange (“Amex”). Accordingly, Pillarstone’s common shares were delisted from the Amex and commenced being quoted on the Over-The-Counter Bulletin Board (“OTC Bulletin Board”), the Pink Market, and currently on the Expert Market under the symbol “~~PRLE~~PRLEQ”.

From 2006 until December 2016, the Company continued its existence as a corporate shell filing its quarterly and annual reports with the Securities and Exchange Commission ("SEC") so that it could be used for future real estate transactions. During this time, the Company was funded by the trustees who contributed $500,000 in exchange for 125,000 Class C Convertible Preferred Shares and $197,780 in exchange for convertible notes payable. In 2016, the shareholders of Pillarstone approved changing the Company's name from Paragon Real Estate Equity and Investment Trust to Pillarstone Capital REIT.

Substantially all of our business is conducted through Pillarstone Capital REIT Operating Partnership LP, a Delaware limited partnership organized in 2016 (“Pillarstone OP”). We are the sole general partner of Pillarstone OP. As of December 31, ~~2022~~2023, we owned 18.6% of the outstanding equity in Pillarstone OP and ~~fully~~ consolidate it onin our financial statements.

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 owns approximately 81.4% and Pillarstone owns approximately 18.6% of the outstanding equity in Pillarstone OP, which is fully consolidated on Pillarstone's financial statements.2

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.

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 ~~owns~~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 ~~has~~ 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.

~~Page~~In 72023, we continued our work to restore operations that were disrupted by Whitestone’s abrupt termination as manager of 63 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.

~~Table~~On December 1, 2023, Whitestone Uptown Tower, LLC filed a voluntary petition for relief under Chapter 11 of ~~Contents~~ 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 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. See Item 3, “Legal Proceedings.”

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. We are considering our strategic plans ~~based~~following on the outcome of the ~~proceedings in the~~ bankruptcy cases.

Competition

We compete for the acquisition of properties and leasing spaces to tenants with many entities, including, among others, publicly traded REITs, life insurance companies, pension funds, partnerships and individual investors. Many competitors have substantially greater financial resources than us. In addition, certain competitors may be willing to accept lower returns on their investments and leases. If competitors prevent us from buying properties that may be targeted for acquisition or leasing our properties to our existing or potential tenants, our capital appreciation and valuation, and our results of operations and financial condition, may be impacted.

Employees

As of December 31, ~~2022~~2023, we had nonine employees, other than our three executive officers. ~~Our operations were conducted by third-party consultants and contractors under the oversight of our management team.~~

Regulatory Matters

Our properties are subject to various covenants, laws, ordinances and regulations, including those relating to common areas and fire and safety requirements.

Federal, state and local environmental laws and regulations regulate releases of hazardous or toxic substances into the environment. Under certain of these laws and regulations, a current or previous owner, operator or tenant may be required to investigate and clean-up hazardous or toxic substances or petroleum product releases or threats of releases, and may be held liable to a government entity or third parties for property damage and for investigation, clean-up and monitoring costs incurred by those parties in connection with actual or threatened contamination. These laws typically impose clean-up responsibility and liability without regard to fault, or whether or not the owner, operator or tenant knew of or caused the contamination. The liability may be joint and several for the full amount of the investigation, clean-up and monitoring costs incurred or to be incurred or actions to be undertaken, although a party held jointly and severally liable may seek contributions from other identified, solvent, responsible parties for their fair share toward these costs. In addition, strict environmental laws regulate a variety of activities that can occur on a property, including the storage of petroleum products or other hazardous or toxic substances, air emissions and water discharges. Such laws may impose fines or penalties for violations. If we do incur material environmental liabilities in the future, our business, financial condition, results of operations, cash flow or our ability to satisfy our financial obligations could be materially adversely affected.

Under the Americans with Disabilities Act of 1990, as amended (the “ADA”), all public accommodations must meet federal requirements related to access and use by disabled persons. Although we believe that our properties, to the extent such properties are “public accommodations” as defined under the ADA, substantially comply with present requirements of the ADA, we have not conducted an audit or investigation of all of our properties to determine our compliance. If one or more of our properties or future properties are not in compliance with the ADA, we may be required to take remedial action which would require us to incur additional costs to bring the property into compliance. We cannot predict the ultimate amount, if any, of the cost of compliance with the ADA or the cost of any damages or attorney’s fees to private litigants or any fines imposed by the federal government in respect of any failure to comply with the ADA.

Whitestone was contracted to perform and maintain the records and processes for much of our accounting and financial reporting functions. As part of the termination of the management agreements, Whitestone removed our access to its accounting and financial software platform. To date, Whitestone has not provided us with a complete electronic copy of our financial and accounting records, as kept and maintained on the software platform. As a result of the abrupt termination of the management agreements, inadequate assistance in the transition of the management of the Real Estate Assets, and Whitestone’s failure to provide a complete copy of our accounting and financial reporting information that was maintained on Whitestone’s accounting and software platform, we are having to rebuild our internal accounting and financial reporting processes.4

In the meantime, we are continuing to rebuild our accounting and financial reporting system and intend as soon as possible to resume timely filing of our current, quarterly and annual reports under the Exchange Act and to file any delinquent reports. We cannot provide assurance at this time as to if or when we will be able to complete such filings.

Under the Pillarstone OP limited partnership agreement, Whitestone OP has the right to require Pillarstone OP to redeems its partnership interests for cash. We have the right to assume directly and satisfy the redemption in the form of cash or common shares. The Status Quo Order prevents Whitestone from exercising its redemption right. In addition, our amended petition in the Texas lawsuit argues that Whitestone’s material breaches of contract and fiduciary duty operate to discharge and/or excuse any obligation to perform under the redemption provisions of the Pillarstone OP limited partnership agreement.

Whitestone has indicated to us that it intends to exercise its redemption right. Whitestone has stated publicly that it intends to monetize its investment in Pillarstone OP. If Whitestone is 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 the Real Estates 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. If Whitestone is permitted to exercise its redemption for common shares, it could constitute a change of control of us and give Whitestone the ability to monetize its interest in Pillarstone OP for the benefit of Whitestone shareholders and not necessarily in the best interests of the other holders of common shares.

Based on Whitestone’s performance under the management agreements and their public statements regarding its intentions to monetize its investment in Pillarstone OP, we do not believe that Whitestone’s actions in connection with the exercise of the redemption rights will respect the rights of the holders of our common shares. The Pillarstone OP limited partnership agreement 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. Accordingly, we intend to vigorously defend the Delaware action and to vigorously pursue the Texas action to seek damages from Whitestone due to its violations of the management agreements and fiduciary duties and to protect our shareholders from the further harms that Whitestone has indicated it intends to inflict on us and our shareholders.

We discovered significant deferred maintenance and neglect of our assets had occurred under Whitestone’s management. Our efforts to address these matters have in some cases been stymied by Whitestone’s litigation against us in Delaware where the court has 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 in this report. As a result, on September 16, 2022, we filed a lawsuit against Whitestone TRS, Inc., Whitestone REIT and Whitestone OP 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.

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.

In addition, Whitestone has challenged our ability to be reimbursed by Pillarstone OP for our expenses, including our litigation expenses in the Delaware case and in our bankruptcy case. We are actively fighting this challenge in the course of our bankruptcy case. If we do not prevail on this issue, we may not have the resources to challenge any further proceedings in the Delaware case or seek some or all of the recoveries we seek in the Houston case. We believe Whitestone’s assertion of damages in the Delaware case to be erroneous and unsupported by the facts, but if we do not have the resources to oppose their claim, we could be subject to damages that would leave us with no assets and the value of our common shares would be worthless.

This litigation 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.

Since the termination of our management agreements by Whitestone, we have incurred significant losses, which raises substantial doubt about our ability to continue as a going concern.

The accompanying financial statements have been prepared assuming that we will continue as a going concern. As discussed in Note 1 to the consolidated financial statements included in this report, we have incurred significant losses since the year ended December 31, 2020 and have an accumulated deficit of approximately $2325.4 million as of December 31, ~~2022~~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 ~~owns~~owned 81.4% of Pillarstone OP as a non-controlling limited partner. 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 isfollowing ~~expected~~the toperiod ~~continue~~covered by this report continued to be, expensive, lengthy, and disruptive to normal business operations. Moreover, the results of these proceedings had been, and following the period covered by this report are expected to continue to be, 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.

WeUntil ~~are~~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. ~~Historically,~~Our wedebts have ~~financed~~been repaid from the proceeds from these sales of our ~~long-term~~Real ~~capital~~Estate ~~needs,~~Assets ~~including~~in ~~acquisitions~~accordance with our plan of liquidation and the Whitestone Uptown Tower, asLLC ~~follows:~~plan of reorganization following the period covered by this report.

We have been developing strategies for the Real Estate Assets in order to create value for the enterprise and our shareholders and selling assets to pay off some of our debt. To implement the strategy to create value with the Real Estate Assets, 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.5

We have identified a material weakness in our internal controls over financial reporting. If we fail to maintain an effective system of internal controls, such failure could cause investors to lose confidence in our reported financial information, which could harm our business and have a material adverse effect on the price of our common shares.

InManagement ~~2022, management~~ identified material weaknesses in our internal controls over financial reporting including:

●

we did not design and implement logical access controls for certain financially relevant systems. Business process, 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 concluded that as of December 31, ~~2022~~2023 and continuing to the date of the filing of this report, 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.

These material weaknesses arose in large part because of Whitestone’s abrupt termination in August 2022 of managerial services it provided, on-going litigation with Whitestone and the subsequent bankruptcy filings. 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~~Our ~~year-end~~efforts were stymied first by Whitestone’s litigation against us in Delaware where the Delaware court limited our ability to incur expenses above low threshold amounts and then by the subsequent bankruptcy filings in 2023 and 2024. 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. The Company’s efforts include implementing aan ~~new~~ enterprise-wide system ~~that~~of ~~will~~our ~~help us in reducing reliance on manual processes and spreadsheets supporting the financial statements~~own. This implementation was completed in 2023. We are using contract personnel for specialized accounting and financial reporting roles.

While we believe that these efforts have improved 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.

We face risks due to lack of geographic diversity.

During the period covered by this report, all of our properties were located in Dallas and Houston. A downturn in general economic conditions and local real estate conditions in these geographic regions, as a result of oversupply of or reduced demand for industrial, office, and warehouse properties, local business climate, business layoffs, and changing demographics, would have a particularly strong adverse effect on us.

We may be affected negatively by tenant bankruptcies and leasing delays.

At any time, a tenant may experience a downturn in its business that may weaken its financial condition. Similarly, a general decline in the economy may result in a decline in the demand for space at our industrial properties. As a result, our tenants may delay lease commencement, fail to make rental payments when due, or declare bankruptcy. Any such event could result in the termination of that tenant’s lease and losses to us. We receive a substantial portion of our income as rents under leases. If tenants are unable to comply with the terms of their leases for any reason, including because of rising costs or falling sales, we may deem it advisable to modify lease terms to allow tenants to pay a lower rent or a smaller share of taxes, insurance, and other operating costs. If a tenant becomes insolvent or bankrupt, we cannot be sure that we would recover the premises from the tenant promptly or from a trustee or debtor-in-possession in any bankruptcy proceeding relating to the tenant. We also cannot be sure that we would receive rent in the proceeding sufficient to cover our expenses with respect to the premises. If a tenant becomes bankrupt, the federal bankruptcy code will apply and, in some instances, may restrict the amount and recoverability of our claims against the tenant. A tenant’s default on its obligations to us could adversely affect our cash flow, financial condition and results of operations.

We face potential difficulties or delays renewing leases or re-leasing space.

WeDuring ~~derive~~the period covered by this report, we derived most of our income from rent received from our tenants. If a tenant experiences a downturn in its business or other types of financial distress, it may be unable to make timely rental payments. Also, when our tenants decide not to renew their leases, renew for less space or terminate early, we may not be able to re-lease the space or there could be a substantial delay in re-leasing the space. Even if tenants decide to renew or lease new space, the terms of renewals or new leases, including the cost of required renovations or concessions to tenants, may be less favorable to us than current lease terms. As a result, our cash flows, results of operations and financial condition could be adversely affected.

Uncertain economic conditions may adversely impact current tenants in our various markets and, accordingly, could affect their ability to pay rent owed to us pursuant to their leases. In periods of economic uncertainty, tenants are more likely to downsize and/or to declare bankruptcy; and, pursuant to various bankruptcy laws, leases may be rejected and thereby terminated. Furthermore, our ability to sell or lease our properties at favorable rates, or at all, may be negatively impacted by general or local economic conditions.

Our ability to collect rent from tenants may affect our ability to pay for adequate maintenance, insurance, and other operating costs, including real estate taxes. Also, the expense of owning and operating a property is not necessarily proportionally reduced when circumstances such as reduced occupancy or other market factors cause a reduction in income from the property. If a property is mortgaged and we are unable to meet the mortgage payments, the lender could foreclose on the mortgage and take title to the property. In addition, interest rates, financing availability, law changes, and governmental regulations (including those governing usage, zoning, and taxes) may adversely affect our financial condition and results of operations.

We face risks associated with our property development.

We intend to continue to develop properties where we believe market conditions warrant such investment. Once made, our investments may not produce results in accordance with our expectations. Risks associated with our current and future development and construction activities include:

• the availability of favorable financing alternatives; • the risk that we may not be able to obtain land on which to develop or that due to the increased cost of land, our activities may not be as profitable; • project costs exceeding original estimates due to rising interest rates and increases in the costs of materials and labor; • disruption in supply and delivery chains; • construction and lease-up delays resulting in increased debt service, fixed expenses, and construction costs; • expenditure of funds and devotion of management’s time to projects that we do not complete; • fluctuations of occupancy and rental rates at newly completed properties, which depend on a number of factors, including market and economic conditions and competition for tenants, resulting in higher than expected rent abatements, capital improvement expenditures, and tenant improvement and other concessions, and lower than expected rental rates, and a corresponding lower return on our investment; and • complications (including building moratoriums and anti-growth legislation) in obtaining necessary zoning, occupancy and other governmental permits.

• the risk that we may not be able to obtain land on which to develop or that due to the increased cost of land, our activities may not be as profitable;

• project costs exceeding original estimates due to rising interest rates and increases in the costs of materials and labor;

• disruption in supply and delivery chains;

• construction and lease-up delays resulting in increased debt service, fixed expenses, and construction costs;

• expenditure of funds and devotion of management’s time to projects that we do not complete;

• fluctuations of occupancy and rental rates at newly completed properties, which depend on a number of factors, including market and economic conditions and competition for tenants, resulting in higher than expected rent abatements, capital improvement expenditures, and tenant improvement and other concessions, and lower than expected rental rates, and a corresponding lower return on our investment; and

• complications (including building moratoriums and anti-growth legislation) in obtaining necessary zoning, occupancy and other governmental permits.

We face risks associated with property acquisitions.

We have acquired portfolios of properties and intend to continue to do so. Our acquisition activities and their success are subject to the following risks:

• even if we enter into an acquisition agreement for a property, we may be unable to complete that acquisition after making a non-refundable deposit and incurring certain other acquisition-related costs; • we may be unable to obtain or assume financing for acquisitions on favorable terms or at all; • the acquisition agreement will likely contain conditions to closing, including completion of due diligence investigations to our satisfaction or other conditions that are not within our control, which may not be satisfied; • acquired properties may be located in new markets where we may face risks associated with a lack of market knowledge or understanding of the local economy, lack of business relationships in the area, costs associated with opening a new regional office, and unfamiliarity with local governmental and permitting procedures; • we may acquire real estate through the acquisition of the ownership entity subjecting us to the risks of that entity; • acquired properties may fail to perform as we project; • the actual costs of repositioning or redeveloping acquired properties may be higher than our estimates; • acquired properties may be located in new markets where we face risks associated with an incomplete knowledge or understanding of the local market, a limited number of established business relationships in the area and a relative unfamiliarity with local governmental and permitting procedures;

~~• we may be unable to obtain or assume financing for acquisitions on favorable terms or at all;~~7

• ~~the~~we ~~acquisition~~may ~~agreement~~be ~~will~~unable ~~likely~~to ~~contain~~quickly ~~conditions~~and toefficiently ~~closing~~integrate new acquisitions, ~~including~~particularly ~~completion~~acquisitions of ~~due~~portfolios ~~diligence~~of ~~investigations~~properties, tointo our ~~satisfaction~~existing operations, and as a result, our results of operations and financial condition could be adversely affected; and • we may acquire properties subject to liabilities and without any recourse, or ~~other~~with ~~conditions~~only ~~that~~limited ~~are~~recourse, ~~not~~to ~~within~~the ~~our~~transferor ~~control~~with respect to unknown liabilities. As a result, if a claim were asserted against us based upon ownership of those properties, we might have to pay substantial sums to settle it, which ~~may~~could ~~not~~adversely beaffect ~~satisfied;~~our cash flow.

• acquired properties may be located in new markets where we may face risks associated with a lack of market knowledge or understanding of the local economy, lack of business relationships in the area, costs associated with opening a new regional office, and unfamiliarity with local governmental and permitting procedures;

• we may acquire real estate through the acquisition of the ownership entity subjecting us to the risks of that entity;

• acquired properties may fail to perform as we project;

• the actual costs of repositioning or redeveloping acquired properties may be higher than our estimates;

• acquired properties may be located in new markets where we face risks associated with an incomplete knowledge or understanding of the local market, a limited number of established business relationships in the area and a relative unfamiliarity with local governmental and permitting procedures;

• we may be unable to quickly and efficiently integrate new acquisitions, particularly acquisitions of portfolios of properties, into our existing operations, and as a result, our results of operations and financial condition could be adversely affected; and

• we may acquire properties subject to liabilities and without any recourse, or with only limited recourse, to the transferor with respect to unknown liabilities. As a result, if a claim were asserted against us based upon ownership of those properties, we might have to pay substantial sums to settle it, which could adversely affect our cash flow.

We may face competition for acquisition opportunities with other investors, and this competition may adversely affect us by subjecting us to the following risks:

• we may be unable to acquire a desired property because of competition from other well-capitalized real estate investors, including publicly traded and private REITs, institutional investment funds and other real estate investors; and • even if we are able to acquire a desired property, competition from other real estate investors may significantly increase the purchase price.

• even if we are able to acquire a desired property, competition from other real estate investors may significantly increase the purchase price.

We face risks due to the illiquidity of real estate which may limit our ability to vary our portfolio.

Real estate investments are relatively illiquid and can be difficult to sell and convert to cash quickly. Our ability to sell one or more of our properties, whether in response to any changes in economic or other conditions or in response to a change in strategy, may be limited. In the event we want to sell a property, we may not be able to do so in the desired time period, the sales price of the property may not meet our expectations or requirements, and/or we may be required to record an impairment on the property as a result.

Coverage under our existing insurance policies may be inadequate to cover losses.

We generally maintain insurance policies related to our business, including casualty, general liability, and other policies, covering our business operations, employees and assets as appropriate for the markets where our properties and business operations are located. However, we would be required to bear all losses that are not adequately covered by insurance. In addition, there may be certain losses that are not generally insured against or that are not generally fully insured against because it is not deemed economically feasible or prudent to do so, including losses due to floods, wind, earthquakes, acts of war, acts of terrorism, or riots. For example, our elevators at our Uptown Tower property have undergone significant renovation and repairs, some of which were covered by insurance. If an uninsured loss or a loss in excess of insured limits occurs with respect to one or more of our properties, then we could be liable for the excess expenses involved in the loss, and we could lose the capital we invested in the properties, as well as the anticipated future revenue from the properties. In addition, if the damaged properties are subject to recourse indebtedness, we would continue to be liable for the indebtedness, even if these properties were irreparably damaged. Property ownership also involves potential liability to third parties for such matters as personal injuries occurring on the property. Such losses may not be fully insured. In addition to uninsured losses, various government authorities may condemn all or parts of operating properties. Such condemnations could adversely affect the viability of such projects.

We face risks in attracting and retaining key personnel.

Our senior executives have strong industry reputations, which aid us in identifying acquisition and development opportunities and negotiating with tenants and sellers of properties. As of the date of this report, we do not have employment agreements with our senior executives. The loss of the services of these key personnel could affect our operations because of diminished relationships with existing and prospective tenants, property sellers and industry personnel. In addition, attracting new or replacement personnel may be difficult in a competitive market.

We face risks associated with security breaches through cyber attacks or cyber intrusions, as well as other significant disruptions of our information technology (“IT”) networks and related systems.

We face risks associated with security breaches or disruptions, whether through cyber attacks or cyber intrusions over the internet, malware, computer viruses, attachments to emails, persons inside our organization, persons with access to systems inside our organization, and other significant disruptions of our IT networks and related systems. The risk of a security breach or disruption, particularly through cyber attacks or cyber intrusion, including by computer hackers, foreign governments, and cyber terrorists, has generally increased as the number, intensity, and sophistication of attempted attacks and intrusions from around the world have increased. Our IT networks and related systems are essential to the operation of our business and our ability to perform day-to-day operations (including managing our building systems) and, in some cases, may be critical to the operations of certain of our tenants. While, to date, we have not had a significant cyber breach or attack that had a material impact on our business or results of operations, there can be no assurance that our efforts to maintain the security and integrity of these types of IT networks and related systems will be effective or that attempted security breaches or disruptions will not be successful or damaging. For example, during the term of the management agreements with Whitestone, Whitestone managed our IT systems and was subject to a ransomware attack that affected our documents, and we cannot be sure of the extent of the damage done to our files despite Whitestone’s recovery of its data files after its payment of the ransom. Following the termination of the management agreements, we have worked on separating our information technology systems from those implemented and maintained by Whitestone. A security breach or other significant disruption involving our IT networks and related systems could adversely impact our financial condition, results of operations, cash flows, liquidity, and the market price of our common shares and would require significant management attention and resources to remedy any resulting damages. A security breach or other significant disruption involving our IT networks and systems could result in our inability to maintain the building systems relied upon by our tenants for their efficient use of their leased space, and the continuation of that circumstance could entitle the affected tenants to abate a portion of their rent. Further, one or more of our tenants could experience a cyber incident which could impact their operations and ability to perform under the terms of their lease with us. As cyber threats continue to evolve, we may be required to expend additional resources to continue to enhance our information security measures and to investigate and remediate any information security vulnerabilities.

In addition, an increase in interest rates could decrease the amounts third-parties are willing to pay for our assets, thereby limiting our ability to change our portfolio promptly in response to changes in economic or other conditions.

~~Page~~As 15we incur indebtedness, we are likely to need to refinance at least a portion of 63 our outstanding debt as it matures. There is a risk that we may not be able to refinance existing debt or that the terms of any refinancing will not be as favorable as the terms of our existing debt. For example, Whitestone Uptown Tower, LLC, Pillarstone OP’s subsidiary that owned the Uptown Tower office building, was the borrower under a mortgage loan agreement during the period covered by this report. We were not able to refinance the mortgage loan for our Uptown Tower property, resulting in the filing of a bankruptcy petition for the borrower. We deconsolidated Whitestone Uptown Tower, LLC from our consolidated financial statements effective December 1, 2023, the date of its bankruptcy filing. As such, Whitestone Uptown Tower, LLC’s financial condition and results of operations are no longer presented in our consolidated financial statements after this date.

~~Table~~If principal payments due at maturity cannot be refinanced, extended, or repaid with proceeds from other sources, such as new equity capital, our cash flow may not be sufficient to repay all maturing debt in years when significant “balloon” payments come due. In addition, we may rely on debt to fund a portion of ~~Contents~~ our new investments such as our acquisition and development activity. There is a risk that we may be unable to finance these activities on favorable terms or at all. In addition, an increase in interest rates could decrease the amounts third-parties are willing to pay for our assets, thereby limiting our ability to change our portfolio promptly in response to changes in economic or other conditions. These conditions, which increase the cost and reduce the availability of debt, may continue or worsen in the future.

We face risks associated with the use of debt to fund acquisitions and developments, including refinancing risk.

We are subject to the risks normally associated with debt financing, including the risk that our cash flow will be insufficient to meet required payments of principal and interest. As we incur indebtedness, we are likely to need to refinance at least a portion of our outstanding debt as it matures. There is a risk that we may not be able to refinance existing debt or that the terms of any refinancing will not be as favorable as the terms of our existing debt. For example, Whitestone Uptown Tower, LLC, Pillarstone OP’s subsidiary that owns the Uptown Tower office building, is the borrower under a mortgage loan agreement. We were not able to refinance the mortgage loan for our Uptown Tower property, resulting in the filing of a bankruptcy petition for the borrower.

If principal payments due at maturity cannot be refinanced, extended, or repaid with proceeds from other sources, such as new equity capital, our cash flow may not be sufficient to repay all maturing debt in years when significant “balloon” payments come due. In addition, we may rely on debt to fund a portion of our new investments such as our acquisition and development activity. There is a risk that we may be unable to finance these activities on favorable terms or at all. These conditions, which increase the cost and reduce the availability of debt, may continue or worsen in the future.

Adverse changes in our credit ratings could impair our ability to obtain additional debt and equity financing on favorable terms, if at all.

Our credit ratings are based on our operating performance, liquidity and leverage ratios, overall financial position, and other factors employed by the credit rating agencies in their rating analysis of us. Our credit ratings can affect the amount and type of capital we can access, as well as the terms of any financings we may obtain. There can be no assurance that we will be able to maintain our current credit ratings. In the event our current credit ratings deteriorate, it may be more difficult or expensive to obtain additional financing or refinance existing obligations and commitments. Also, a downgrade in our credit ratings would trigger additional costs or other potentially negative consequences under our current and future credit facilities and debt instruments.

The lack of certain limitations on our ability to incur debt could result in our becoming more highly leveraged. Any additional indebtedness incurred may have a material adverse effect on our financial condition and results of operations.

Our governing documents do not limit the amount of indebtedness we may incur. Accordingly, we may incur additional debt and would do so, for example, to improve or develop our existing properties or to acquire new properties. We might become more highly leveraged as a result, and our financial condition might be negatively affected and the risk of default on our indebtedness could increase.

The incurrence of additional indebtedness could have adverse consequences on our business, such as:

• requiring us to use a substantial portion of our cash flow from operations to service our indebtedness, which would reduce the available cash flow to fund working capital, capital expenditures, development projects, distributions, and other general corporate purposes; • limiting our ability to obtain additional financing to fund our working capital needs, acquisitions, capital expenditures, or other debt service requirements or for other purposes; • increasing our exposure to floating interest rates; • limiting our ability to compete with other companies who have less leverage, as we may be less capable of responding to adverse economic and industry conditions;

~~• limiting our ability to obtain additional financing to fund our working capital needs, acquisitions, capital expenditures, or other debt service requirements or for other purposes;~~9

• restricting us from making strategic acquisitions, developing properties, or capitalizing on business opportunities; • restricting the way in which we conduct our business due to financial and operating covenants in the agreements governing our future indebtedness; • exposing us to potential events of default (if not cured or waived) under covenants contained in our debt instruments; • increasing our ~~exposure~~vulnerability to ~~floating~~a ~~interest~~downturn ~~rates~~in general economic conditions; and • limiting our ability to react to changing market conditions in our industry.

• limiting our ability to compete with other companies who have less leverage, as we may be less capable of responding to adverse economic and industry conditions;

• restricting us from making strategic acquisitions, developing properties, or capitalizing on business opportunities;

• restricting the way in which we conduct our business due to financial and operating covenants in the agreements governing our future indebtedness;

• exposing us to potential events of default (if not cured or waived) under covenants contained in our debt instruments;

• increasing our vulnerability to a downturn in general economic conditions; and

• limiting our ability to react to changing market conditions in our industry.

The impact of any of these potential adverse consequences could have a material adverse effect on our results of operations, financial condition, and liquidity.

Risks Related to the Real Estate Industry

We face risks associated with local real estate conditions in areas where we own properties.

We may be adversely affected by general economic conditions and local real estate conditions. For example, an oversupply of commercial properties in a local area or a decline in the attractiveness of our Real Estate Assets to tenants would have a negative effect on us. Factors that may adversely affect the economic performance and value of our Real Estate Assets include, among other things:

• population and demographic trends; • employment and personal income trends; • income and other tax laws; • changes in interest rates and availability and costs of financing; • increased operating costs, including insurance premiums, utilities, and real estate taxes, due to inflation and other factors which may not necessarily be offset by increased rents; • changes in the price of oil; • construction costs; • weather-related events; • changes in the national, regional, and local economic climate; • local real estate conditions such as an oversupply of rentable space caused by increased development of new properties, a reduction in demand for rentable space caused by a change in the preferences and requirements of our tenants (including space usage), or economic conditions decreasing the desirability of our locations; • the attractiveness of our properties to tenants or buyers; • competition from other available properties; • changes in market rental rates and related concessions granted to tenants including, but not limited to, free rent and tenant improvement allowances; • uninsured losses or losses in excess of our insurance coverage as a result of casualty events or other claims or events; • insolvency of our insurance carriers; • sociopolitical unrest such as political instability, civil unrest, armed hostilities, or political activism resulting in a disruption of day-to-day building operations; • the impact of a public health crisis and the governmental and third party response to such a crisis; • the need to periodically repair, renovate, and re-lease properties; • changes in federal, state, and local income tax laws as they affect real estate companies and real estate investors; and • changes in interest rates and availability of permanent financing sources that may render the sale of a property difficult or unattractive or otherwise reduce returns to shareholders.

• employment and personal income trends;

• income and other tax laws;

• changes in interest rates and availability and costs of financing;

• increased operating costs, including insurance premiums, utilities, and real estate taxes, due to inflation and other factors which may not necessarily be offset by increased rents;

• changes in the price of oil;

• construction costs;

• weather-related events;

• changes in the national, regional, and local economic climate;

• local real estate conditions such as an oversupply of rentable space caused by increased development of new properties, a reduction in demand for rentable space caused by a change in the preferences and requirements of our tenants (including space usage), or economic conditions decreasing the desirability of our locations;

• the attractiveness of our properties to tenants or buyers;

• competition from other available properties;

• changes in market rental rates and related concessions granted to tenants including, but not limited to, free rent and tenant improvement allowances;

• uninsured losses or losses in excess of our insurance coverage as a result of casualty events or other claims or events;

• insolvency of our insurance carriers;

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

• the impact of a public health crisis and the governmental and third party response to such a crisis;

• the need to periodically repair, renovate, and re-lease properties;

• changes in federal, state, and local income tax laws as they affect real estate companies and real estate investors; and

• changes in interest rates and availability of permanent financing sources that may render the sale of a property difficult or unattractive or otherwise reduce returns to shareholders.

We may be unable to compete for properties and tenants.

The real estate business is highly competitive. We compete for interests in properties with other real estate investors and purchasers, some of whom have greater financial resources, revenues and geographical diversity than we have. Furthermore, we compete for tenants with other property owners. All of our Real Estate Assets are subject to significant local competition. We also compete with a wide variety of institutions and other investors for capital funds necessary to support our investment activities and asset growth.

Inflation and related volatility in the economy could negatively impact our tenants, our results of operations, and the value of our publicly-traded equity securities.

Inflation in the United States accelerated rapidly in 2022 and 2023 ~~and is expected to continue at an elevated level in the near-term~~. Inflation and its related impacts, including increased prices for services and goods and higher interest rates and wages, and any fiscal or other policy interventions by the U.S. government in reaction to such events, could negatively impact our tenants’ businesses or our results of operations. We believe we ~~have~~ lost tenants due to inflationary pressures on their businesses in 2022 and 2023. Many of our leases require the tenants to pay their pro rata share of operating expenses, including real estate taxes, insurance and common area maintenance, although a limited number of tenants have capped the amount of these operating expenses they are responsible for under their lease. As a result, we believe that most of our leases mitigate our exposure to increases in costs and operating expenses resulting from inflation. However, there can be no assurance that our tenants would be able to absorb these expense increases and be able to continue to pay us their portion of operating expenses, capital expenditures and rent. In addition, while most of our leases provide for scheduled rent increases, high levels of inflation could outpace these increases. As a result, our business, financial condition, results of operations, cash flows, and liquidity could be adversely affected over time. There is no guarantee that we will be able to mitigate the effects of inflation and related impacts, and the duration and extent of any prolonged periods of inflation, and any related adverse effects on our results of operations and financial condition, remain unknown at this time.

Additionally, inflationary pricing had and may continue to have a negative effect on the construction costs for repairs and improvements and any development projects we may undertake, including, but not limited to, costs of construction materials, labor, and services from third-party contractors and suppliers. For example, we experienced higher tenant improvement costs during 2023.

Inflation may also cause increased volatility in financial markets, which could affect our ability to access the capital markets or impact the cost or timing at which we are able to do so. To the extent our exposure to increases in interest rates on any of our debt is not eliminated through interest rate swaps and interest rate protection agreements, such increases will result in higher debt service costs, which will adversely affect our cash flows. Our exposure to increases in interest rates in the short term includes the anticipated refinancing of our existing loan agreement. Increases in interest rates could increase our debt financing costs over time.

The state of the economy or other adverse changes in general or local economic conditions may adversely affect our operating results and financial condition.

Turmoil in the global financial markets may have an adverse impact on the availability of credit to businesses generally and could lead to a further weakening of the U.S. and global economies. Our ability to access the capital markets may be restricted at a time when we would like, or need, to raise financing, which could have an impact on our flexibility to react to changing economic and business conditions. Furthermore, deteriorating economic conditions including business layoffs, downsizing, industry slowdowns, and other similar factors that affect our tenants could negatively impact commercial real estate fundamentals and result in lower occupancy, lower rental rates, and declining values in our real estate portfolio and in the collateral securing any loan investments we may make. Additionally, an adverse economic situation could have an impact on our lenders or tenants, causing them to fail to meet their obligations to us. No assurances can be given that the effects of an adverse economic situation will not have a material adverse effect on our business, financial condition and results of operations.

Pandemics, such as COVID-19, and mitigation efforts to control their spread may impact our business, financial condition, results of operations and cash flows.

The COVID-19 pandemic, including the ongoing emergence of viral variants, has caused and could continue to cause widespread disruptions to the U.S. and global economy and has contributed to significant volatility and negative pressure in financial markets. Our financial condition, results of operations and cash flows are affected by our ability to lease our properties and collect rental revenues, renew our leases or lease vacant space on favorable terms, and the health and well-being of our tenants, employees, and other stakeholders, all of which could be adversely affected by COVID-19 or other pandemics. In addition, to the extent the COVID-19 pandemic, its macroeconomic effects or the government responses thereto adversely affect our business, financial condition, results of operations and cash flows, they may also have the effect of heightening many of the other risks described in “Item 1A. Risk Factors” in this report.

Compliance or failure to comply with the Americans with Disabilities Act or other safety regulations and requirements could result in substantial costs.

The Americans with Disabilities Act generally requires that certain buildings, including office buildings, residential buildings and hotels, be made accessible to disabled persons. Noncompliance could result in the imposition of fines by the federal government or the award of damages to private litigants. If, under the Americans with Disabilities Act, we are required to make substantial alterations and capital expenditures in one or more of our properties, including the removal of access barriers, it could adversely affect our financial condition and results of operations.

At December 31, 2023, we owned eight Real Estate Assets, including the Uptown Tower property. Our properties are subject to various federal, state and local regulatory requirements, such as state and local fire and life safety requirements. If we fail to comply with these requirements, we could incur fines or private damage awards or our properties could be shut down by enforcement officials. We do not know whether existing requirements will change or whether compliance with future requirements will require significant unanticipated expenditures that will affect our cash flow and results of operations.

Legislative or regulatory action with respect to tax laws and regulations could adversely affect us and our shareholders.

We are subject to state and local tax laws and regulations. Changes in state and local tax laws or regulations may result in an increase in our tax liability. A shortfall in tax revenues for states and municipalities in which we operate may lead to an increase in the frequency and size of such changes. If such changes occur, we may be required to pay additional taxes on our assets or income. These increased tax costs could adversely affect our financial condition and results of operations. Additional changes to tax laws are likely to continue to occur in the future, and we cannot assure our shareholders that any such changes will not adversely affect the taxation of a shareholder. We cannot assure you that future changes to tax laws and regulations will not have an adverse effect on an investment in our stock.

We are subject to environmental laws and regulations.

Current and previous real estate owners and operators may be required under various federal, state, and local laws, ordinances, and regulations to investigate and clean up hazardous substances released at the properties they own or operate. They may also be liable to the government or to third parties for substantial property or natural resource damage, investigation costs, and cleanup costs. Such laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the release or presence of such hazardous substances. In addition, some environmental laws create a lien on the contaminated site in favor of the government for damages and costs the government incurs in connection with the contamination. Contamination may adversely affect the owner’s ability to use, sell, or lease real estate or to borrow using the real estate as collateral. We have no way of determining at this time the magnitude of any potential liability to which we may be subject arising out of environmental conditions or violations with respect to the properties we currently or formerly owned. Environmental laws today can impose liability on a previous owner or operator of a property that owned or operated the property at a time when hazardous or toxic substances were disposed of, released from, or present at the property. A conveyance of the property, therefore, may not relieve the owner or operator from liability. Moreover, material environmental liabilities or compliance concerns may exist, of which we are currently unaware, that in the future may have a material adverse effect on our business, assets or results of operations.

Climate change and its effects, including compliance with new laws or regulations such as “green” building codes, may require us to make improvements to our existing properties or result in unanticipated losses that could affect our business and financial condition.

To the extent that climate change causes an increase in catastrophic weather events, such as severe storms, fires or floods, our properties may be susceptible to an increase in weather-related damage. Even in the absence of direct physical damage to our properties, the occurrence of any natural disasters or a changing climate in the area of any of our properties could have a material adverse effect on business, supply chains and the economy generally. Climate change could cause an increase in property and casualty insurance premiums. The potential impacts of future climate change on our properties could adversely affect our ability to lease, develop, or sell our properties or to borrow using our properties as collateral. In addition, any proposed legislation or regulatory actions enacted to address climate change could increase the costs of energy, utilities, and overall development. The resulting costs of any proposed legislation or regulatory action may adversely affect our financial position, results of operations, and cash flows.

Risks Related to the Ownership of Our Common Shares

The market price of our common shares may fluctuate.

The market price of our common shares has been, and may continue to be, subject to fluctuation due to many events and factors such as those described in this report, including:

• quarterly variations in operating results; • changes in market valuations of other similar companies; • actual or anticipated variations in our operating results, funds from operations, or liquidity; • the general reputation of real estate as an attractive investment in comparison to other equity securities and/or the reputation of the product types of our assets compared to other sectors of the real estate industry; • material changes in any significant tenant industry concentration; • material changes in market concentrations; • the general stock and bond market conditions, including changes in interest rates or fixed income securities; • changes in tax laws; • changes in market valuations of our properties; • adverse market reaction to the amount of our outstanding debt at any time, the amount of our maturing debt, and our ability to refinance such debt on favorable terms; • any failure to comply with existing debt covenants; • any foreclosure or deed in lieu of foreclosure of our properties; • additions or departures of trustees, key executives, and other employees;

~~• changes in market valuations of other similar companies;~~12

• ~~actual~~actions orby ~~anticipated~~institutional ~~variations~~shareholders; • uncertainties in ~~our~~world ~~operating~~financial ~~results,~~markets; ~~funds~~• ~~from~~general ~~operations~~market and economic conditions; in particular, ormarket ~~liquidity~~and economic conditions of Dallas and Houston; and • the realization of any of the other risk factors described in this report.

• the general reputation of real estate as an attractive investment in comparison to other equity securities and/or the reputation of the product types of our assets compared to other sectors of the real estate industry;

• material changes in any significant tenant industry concentration;

• material changes in market concentrations;

• the general stock and bond market conditions, including changes in interest rates or fixed income securities;

• changes in tax laws;

• changes in market valuations of our properties;

• adverse market reaction to the amount of our outstanding debt at any time, the amount of our maturing debt, and our ability to refinance such debt on favorable terms;

• any failure to comply with existing debt covenants;

• any foreclosure or deed in lieu of foreclosure of our properties;

• additions or departures of trustees, key executives, and other employees;

• actions by institutional shareholders;

• uncertainties in world financial markets;

• general market and economic conditions; in particular, market and economic conditions of Dallas and Houston; and

• the realization of any of the other risk factors described in this report.

Furthermore, the stock markets recently have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political and market conditions such as recessions, interest rate changes, international currency fluctuations or political unrest, may negatively impact the market price of our common shares. In the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could harm our business.

Many of the factors listed above are beyond our control. Those factors may cause the market price of our common shares to decline, regardless of our financial performance, condition, and prospects. The market price of our common shares may fall significantly in the future, and it may be difficult for our shareholders to resell our common shares at prices they find attractive.

We do not qualify as a REIT.

Since we do not qualify as a REIT, we are not be allowed to deduct dividends to shareholders in computing our taxable income and are subject to federal income tax at regular corporate rates. The additional tax incurred at regular corporate rates could significantly reduce the cash flows. Furthermore, we are not required by the Internal Revenue Code to make any dividends to our shareholders as a condition to maintain REIT qualification. The REIT qualification requirements are extremely complex, and interpretation of the U.S. federal income tax laws governing REIT qualification is limited. There can be no assurance that we will meet REIT qualifications in the future. In addition, facts and circumstances that may be beyond our control may affect our ability to qualify as a REIT. We cannot assure you that new legislation, regulations, administrative interpretations, or court decisions will not change the tax laws significantly with respect to any future attempts to qualify as a REIT or with respect to the federal income tax consequences of qualification.

Certain provisions of our declaration of trust and bylaws may inhibit a change of our control.

Certain provisions contained in our declaration of trust and bylaws and the Maryland General Corporation Law may discourage a third party from making a tender offer or acquisition proposal to us. If this were to happen, it could delay, deter, or prevent a change in control or the removal of existing management. These provisions also may delay or prevent our shareholders from receiving a premium for their common shares over then-prevailing market prices. These provisions include:

• no cumulative voting in the election of trustees, which limits the ability of minority shareholders to elect trustee candidates; • a classified board of trustees; • the exclusive right of our board of trustees to elect a trustee to fill a vacancy created by the expansion of the board of trustees or the resignation, death or removal of a trustee, which prevents shareholders from being able to fill vacancies on our board of trustees; • the ability of our board of trustees to determine to issue preferred shares and to determine the price and other terms of those shares, including preferences and voting rights, without shareholder approval, which could be used to significantly dilute the ownership of a hostile acquirer; • a prohibition on shareholder action by written consent by less than unanimous consent, which may force shareholder action to be taken at an annual or special meeting of our shareholders; and • advance notice procedures that shareholders must comply with in order to nominate candidates to our board of trustees or to propose matters to be acted upon at a shareholders’ meeting, which may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the acquiror’s own slate of trustees or otherwise attempting to obtain control of us.

• a classified board of trustees;

• the exclusive right of our board of trustees to elect a trustee to fill a vacancy created by the expansion of the board of trustees or the resignation, death or removal of a trustee, which prevents shareholders from being able to fill vacancies on our board of trustees;

• the ability of our board of trustees to determine to issue preferred shares and to determine the price and other terms of those shares, including preferences and voting rights, without shareholder approval, which could be used to significantly dilute the ownership of a hostile acquirer;

• a prohibition on shareholder action by written consent by less than unanimous consent, which may force shareholder action to be taken at an annual or special meeting of our shareholders; and

• advance notice procedures that shareholders must comply with in order to nominate candidates to our board of trustees or to propose matters to be acted upon at a shareholders’ meeting, which may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the acquiror’s own slate of trustees or otherwise attempting to obtain control of us.

In addition, Maryland law provides protection for Maryland corporations against unsolicited takeovers by limiting, among other things, the duties of the trustees in unsolicited takeover situations and certain “business combinations” and “control share acquisitions.” Our bylaws contain provisions exempting us from the Maryland Control Share Acquisition Act and the Maryland Business Combination Act. Our bylaws prohibit the repeal, amendment or alteration of our Maryland Control Share Acquisition opt out without the approval by the Company’s shareholders; however, there can be no assurance that this provision will not be amended or eliminated at some time in the future.

A small number of existing shareholders control our company, which could limit your ability to influence the outcome of shareholder votes.

Our trustees beneficially own approximately 6254.5% of our common shares and approximately 44.6% of our total common shares and preferred shares, on an as-converted basis, as of June 301, ~~2025~~2026. As a result, these persons may be able to exercise significant influence over the outcome of shareholder votes, including votes concerning the election of trustees, the adoption or amendment of provisions in our declaration of trust or bylaws and the approval of mergers and other significant corporate transactions.

We are subject to the reporting requirements of the federal securities laws, which can be expensive.

We are a public reporting company in the United States and therefore, we are subject to the information and reporting requirements of the Securities Exchange Act of 1934 and other federal securities laws, and the compliance obligations of the Sarbanes-Oxley Act. The costs of preparing and filing annual and quarterly reports and other information with the SEC will cause our expenses to be higher than they would be if we were a privately-held company.

The issuance or sale of equity, convertible or exchangeable securities in the market, or the perception of such future sales or issuances, could lead to a decline in the price, if any, of our common shares.

Our board of trustees has the authority to issue up to 450,000,000 common shares and 50,000,000 preferred shares of beneficial interest. Any issuance of equity or securities convertible into or exchangeable for our equity securities, including for the purposes of expansion of our business, may have a dilutive effect on our existing shareholders.

The perceived risk associated with the possible issuance of a large number of common shares or securities convertible into or exchange for a large number of common shares could cause some of our shareholders to sell their shares, thus causing the price of our shares to decline. Subsequent sales of common shares in the open market or the private placement of common shares or securities convertible into or exchangeable for common shares could also have an adverse effect on the market price, if any, of our common shares. If our common shares price declines, it may be more difficult for us to or we may be unable to raise additional capital.

Page 21 of 63

Table of Contents

We may conduct further equity offerings in the future. If common shares are issued in return for additional funds, property or services, the price per share could be lower than that paid by our current shareholders. Also, any capital stock we sell in the future may be valued on an arbitrary basis by us and the issuance of capital stock for future services, acquisitions, or other corporate actions may have the effect of diluting the value of the shares held by our existing shareholders.

Future sales of substantial amounts of our currently outstanding common shares in the public market, or the perception that such sales could occur, could adversely affect prevailing trading prices of our common shares and could impair our ability to raise capital through future offerings of equity or equity-related securities. We cannot predict what effect, if any, future sales of our common shares, or the availability of shares for future sales, will have on the market price of our common shares.

Because our shares are deemed “penny stock,” you may have difficulty selling them in the secondary trading market.

The SEC has adopted regulations which generally define a “penny stock” to be any equity security that has a market price of less than $5.00 per share or with an exercise price of less than $5.00 per share. Additionally, if the equity security is not registered or authorized on a national securities exchange, the equity security also would constitute a “penny stock.” As our common shares fall within the definition of penny stock, these regulations require the delivery, prior to any transaction involving our common shares, of a risk disclosure schedule explaining the penny stock market and the risks associated with it. Disclosure is also required to be made regarding compensation payable to both the broker-dealer and the registered representative and current quotations for the securities. In addition, monthly statements are required to be sent disclosing recent price information for the penny stocks. The ability of broker-dealers to sell our common shares and the ability of shareholders to sell our common shares in the secondary market may be limited. As a result, the market liquidity for our common shares may be severely and adversely affected. We can provide no assurance that trading in our common shares will not be subject to these or other regulations in the future, which would negatively affect the market for our common shares.

Risks Related to Our Bankruptcy

As a result of our bankruptcy cases, we are subject to the risks and uncertainties associated with bankruptcy cases and operating under Chapter 11 may restrict our ability to pursue strategic and operational initiatives.

For the duration of our bankruptcy cases, our operations and our ability to execute our business strategy will be subject to the risks and uncertainties associated with bankruptcy. These risks include:

• our ability to obtain bankruptcy court approval with respect to motions filed in the bankruptcy cases from time to time; • our ability to comply with and operate under the requirements and constraints of applicable bankruptcy laws and under any cash management, cash collateral, adequate protection, or other orders entered by the bankruptcy court from time to time;

• our ability to comply with and operate under the requirements and constraints of applicable bankruptcy laws and under any cash management, cash collateral, adequate protection, or other orders entered by the bankruptcy court from time to time;14

• our ability to engage in intercompany transactions and to fund operations from cash on hand or from financings and, in the event of such financings, our ability to comply with the terms of such financings; • our ability to consummate our plan of liquidation and the Whitestone Uptown Tower plan of reorganization; • our ability to develop, fund, and execute our business plan; and • our ability to continue as a going concern.

•These ~~our~~risks ~~ability~~and touncertainties ~~negotiate~~could affect our business and ~~consummate~~operations ~~our~~in ~~plan~~various ways. For example, transactions outside the ordinary course of ~~liquidation~~business ~~and~~are subject to the ~~Whitestone~~prior ~~Uptown~~approval ~~Tower~~of ~~plan~~the bankruptcy court, which may limit our ability to respond timely to certain events or take advantage of ~~reorganization;~~opportunities.

•In ~~our~~December ~~ability~~2025, tothe ~~develop~~bankruptcy court in the jointly administered bankruptcy cases approved a settlement agreement between the plan agent and Whitestone REIT, ~~fund~~Whitestone REIT Operating Partnership, L.P. and ~~execute~~Whitestone ~~our~~TRS, ~~business~~Inc. ~~plan;~~settling the claims between us and the Whitestone parties and creating reserves for the payment of claims and the administration of the jointly administered bankruptcy estates. The bankruptcy court retains jurisdiction to enforce the settlement agreement or decide any claims or disputes that may arise or result from or be connected with the settlement agreement. Claims in the Whitestone Uptown Tower, LLC bankruptcy case were not settled as part of this agreement and remain outstanding as of the date of this report.

•Because of the risks and uncertainties associated with the bankruptcy cases, 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.

These risks and uncertainties could affect our business and operations in various ways. For example, transactions outside the ordinary course of business are subject to the prior approval of the bankruptcy court, which may limit our ability to respond timely to certain events or take advantage of opportunities. Because of the risks and uncertainties associated with the bankruptcy cases, 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.

Prosecution of the bankruptcy cases has consumed and will continue to consume a substantial portion of the time and attention of our management, which may have an adverse effect on our business and results of operations.

While the bankruptcy cases continue, our management will be required to spend a significant amount of time and effort focusing on the cases. This diversion of attention may materially adversely affect the conduct of our business, and, as a result, our financial condition and results of operations, particularly if the bankruptcy cases continue to be protracted. During the bankruptcy cases, our employees have faced considerable distraction and uncertainty. A loss of key personnel or material erosion of employee morale could have a materially adverse effect on our ability to meet tenant expectations, thereby adversely affecting our business and results of operations. The failure to retain members of our management team and other key personnel could impair our ability to execute our strategy and implement operational initiatives, thereby having a material adverse effect on our financial condition and results of operations.

We are in the process of Chapter 11 reorganization cases under the Bankruptcy Code, which may cause our common shares to decrease in value or may render our common shares worthless.

Following the commencement of the bankruptcy cases, the price of our common shares, Class A Cumulative Convertible Preferred Shares and Our Class C Convertible Preferred Shares may decrease in value or become worthless. Accordingly, any trading in our shares during the pendency of our bankruptcy cases is highly speculative and poses substantial risks to holders and purchasers of our shares. Recoveries in the bankruptcy cases for holders of shares, if any, will depend upon our ability to implement our plans of liquidation and reorganization, the treatment of claims under the plans and the value of our assets. We expect that shareholders would not receive a recovery through any plan unless the holders of more senior claims and interests, such as secured and unsecured indebtedness, are paid in full. We also expect our shareholders’ equity to decrease as we use cash on hand to support our operations in bankruptcy. We may not be able to implement a post-bankruptcy business plan. Consequently, there is a significant risk that the holders of our shares will receive no recovery under the bankruptcy cases and that our shares will be worthless.

Operating in bankruptcy for a long period of time may harm our business.

Prolonged operations under bankruptcy court protection could have a material adverse effect on our business, financial condition, results of operations, and liquidity. So long as we remain subject to bankruptcy court protection or jurisdiction, senior management will be required to spend a significant amount of time and effort dealing with the reorganization instead of focusing exclusively on business operations. A prolonged period of operating under bankruptcy court protection also may continue to make it more difficult to retain management and other key personnel necessary to the success of our business. In addition, the longer we remain under bankruptcy court protection, the more likely it is that tenants and vendors will lose confidence in our ability to reorganize our business successfully and will seek to establish alternative commercial relationships.

Should the time that we remain under bankruptcy court protection be protracted, we may also need to seek new financing to fund operations. If we are unable to obtain such financing on favorable terms or at all, the chances of confirming a Chapter 11 plan may be seriously jeopardized and the likelihood that we will instead be required to liquidate our assets may increase.15

~~Page~~So 23long as we remain under bankruptcy court protection or jurisdiction, we will be required to incur substantial costs for professional fees and other expenses associated with the administration of 63 the bankruptcy cases, including potentially the cost of litigation. In general, litigation can be expensive and time consuming to bring or defend against. Such litigation could result in settlements or damages that could significantly affect our financial results. It is also possible that certain parties will commence litigation with respect to the treatment of their claims under a Chapter 11 plan. It is not possible to predict the potential litigation that we may become party to, nor the final resolution of such litigation. The impact of any such litigation on our business and financial stability, however, could be material.

~~Table~~Item of1C. ~~Contents~~ Cybersecurity.

Our board of trustees provides oversight of risks from cybersecurity threats, in coordination with our management team and the Audit Committee of the board.

The day-to-day management of cybersecurity is the responsibility of our executive officers, and our board of trustees relies on management, in particular our chief executive officer and chief financial officer, to bring significant matters impacting us to its attention, including with respect to material risks from cybersecurity threats. As a small company with few employees, we do not have employees with expertise in assessing and managing cybersecurity risks. We engage a third-party consultants to oversee and monitor our information technology security processes and implemented technologies.

Cybersecurity threats, including as a result of any previous cybersecurity incidents, have not materially affected us or our business strategy, results of operations or financial condition since the termination of our management agreements with Whitestone TRS. For a disclosure of our cybersecurity risks, see the risk factor under the heading “We face risks associated with security breaches through cyber attacks or cyber intrusions, as well as other significant disruptions of our information technology (“IT”) networks and related systems” in Risk Factors in Part I, Item 1A.

Item 3. 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 ~~challenges~~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 ~~claims~~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 ~~prevents~~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 ~~argues~~argued that Whitestone’s material breaches of contract and fiduciary duty ~~operate~~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 ~~intends~~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 ~~have~~ stated that a redemption request would not trigger the Rights Agreement, and our board of trustees ~~has~~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.

Page 25 of 63

Table of Contents

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 ~~have~~were in some cases ~~been~~ stymied by Whitestone’s litigation against us in Delaware where the court ~~has~~ 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~~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. WeThe ~~disagree with the~~ Delaware court’s ~~ruling~~declared ~~and~~the ~~are~~Rights ~~considering~~Agreement ~~our~~unenforceable ~~options~~against ~~for appeal~~Whitestone, ~~subject~~permitted Whitestone OP to tender a ~~final~~notice ~~order~~of ~~being~~redemption ~~entered~~for inits ~~the~~OP ~~case,~~Units and determined that the ~~outcome~~Pillarstone ofOP ~~various~~limited ~~proceedings~~partnership inagreement ~~the~~should ~~jointly~~be ~~administered~~followed ~~bankruptcy~~whereby ~~cases~~we ~~described~~would ~~below~~decide ~~and~~whether ~~the~~to ~~decision~~assume ofPillarstone ~~the~~OP’s ~~plan~~redemption ~~agent~~obligation inand ~~the~~determine ~~bankruptcy~~what ~~cases~~value to ~~pursue~~attribute anto ~~appeal~~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 ~~also~~moved ~~brought~~into as 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 joint plan of liquidation in the bankruptcy case 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 2025.18

The joint 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 ~~the amount~~ of $10,000~~.00~~ 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~~.00~~ 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 “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:

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;

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

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:

the adversary proceeding commenced by Pillarstone OP in the jointly administered bankruptcy cases;

the Houston litigation discussed in “—Houston Case” above; and

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.

AsDuring ofthe year ended December 31, ~~2022~~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.

Page 27 of 63

Table of Contents

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~~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 ~~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 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 ~~have~~were ~~been~~ 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 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. We are holding approximately $13.6 million of the sale proceeds representing 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.

This litigation 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. The registrant believes that the allegations in the Delaware lawsuit are without merit and intends to continue to vigorously defend against them. In addition, we intend to vigorously pursue the Texas action to seek damages from Whitestone due to its violations of the management agreements and fiduciary duties and to protect our shareholders from the further harms that Whitestone has indicated it intends to inflict on us and our shareholders. However, the outcomes of these lawsuits, including the timing of the final disposition of the lawsuits, are unpredictable and could result in substantial costs to us. As a result, future adverse rulings, settlements, or unfavorable developments could result in charges that could have a material adverse effect on the registrant’s business, results of operations or financial condition.21

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.

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 iswas the 81.4% limited partner of Pillarstone OP following the transaction.

~~Page~~In 31connection with the Contribution Agreement, on December 8, 2016, we entered into management agreements with Whitestone TRS, Inc., a subsidiary of 63 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.

Table of Contents

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 with respect to each property, other than Uptown Tower, Whitestone TRS agreed to provide certain property management, leasing and day-to-day advisory and administrative services to such properties in exchange for (1) a monthly property management fee equal to 5.0% of the monthly revenues of each property and (2) a monthly asset management fee equal to 0.125% of GAV (as defined in each Management Agreement as, generally, the purchase price of the respective property based upon the purchase price allocations determined pursuant to the Contribution Agreement, excluding all indebtedness, liabilities or claims of any nature) of such property. 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 in exchange for (1) a monthly property management fee equal to 3.0% of the monthly revenues of Uptown Tower and (2) a monthly asset management fee equal to 0.125% of GAV of Uptown Tower.

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 ~~Pillarstone’s~~our 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 ~~owns~~owned 81.4% of Pillarstone OP as a non-controlling limited partner.

~~This~~Whitestone’s 30-day notice period of termination was insufficient. ~~because~~ Whitestone did not ~~provide~~cooperate ~~the~~with ~~operation~~us ~~and financial database of our information, nor did Whitestone cooperate~~ 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 ~~and have been difficult, expensive and time-consuming to separate~~. 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. ~~Further,~~For ~~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 ~~disruption~~delays toin our business operations and higher costs. In other cases, Whitestone obligated us to long-term contracts for essential services that we cannot easily replace.

Table of Contents

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 ~~have~~had ~~obtained~~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 has neglected to provide us with all of the redevelopment plans for our property portfolio.25

In• ~~addition,~~evaluating the ~~internalization~~redevelopment ~~process~~plans ~~has~~available ~~involved selecting an enterprise resource planning, or ERP, system of our own. Our newly assembled leadership team quickly engaged consultants (a)~~ to ~~assist~~ us inthat ~~implementing~~were ~~the~~developed ~~newly~~but ~~selected~~left ~~ERP~~dormant ~~system,~~during ~~(b)~~the toterm ~~analyze,~~of ~~reconcile~~the ~~and~~management ~~transform~~agreements. ~~historical data obtained from~~ Whitestone ~~into~~neglected ~~a usable format for our new system and (c)~~ to ~~design~~provide ~~procedures~~us ~~for~~with ~~regular~~all ~~accounting closes and preparation~~ of ~~accurate~~the ~~and~~redevelopment ~~reliable~~plans ~~financial statements~~ for our ~~shareholders~~property ~~and other stakeholders~~portfolio.

~~Table~~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 ~~Contents~~ 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.

Lawsuit, Termination of Management Agreements and Bankruptcy Proceedings

On July 12, 2022, we were named as a defendant in a lawsuit filed in the Court of Chancery of the State of Delaware by Whitestone OP. The suit challenges 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 claims 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.

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 Item 3, “Legal Proceedings—Uptown Tower”, and the other claims were settled pursuant to the settlement agreement described in Item 3, “Legal Proceedings—Jointly Administered Bankruptcy Cases.”

~~Page~~On 34July 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 63 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.

~~Page~~In 36July 2022, Whitestone terminated leases with us for approximately 12,400 square feet at three Real Estate Assets that it maintained as it acted as manager of 63 the Real Estate Assets. Whitestone’s lease terminations 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 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 $8.94 million for the year ended December 31, ~~2022~~2023 compared to $85.08 million for ~~2021~~2022, an increase of $~~853~~2.6 ~~thousand~~million, or 1145%. 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. Legal expenses, principally associated with the Whitestone litigation, totaled $~~855~~2.4 ~~thousand~~million in ~~2022.~~2023 Inand ~~2021, our legal expenses were~~ $69855 thousand in 2022. The primary components of operating expenses are detailed in the table below (in thousands):

Our effective tax rate for the years ended December 31, ~~2022~~2023 and ~~2021~~2022 was 14(16%) and 014%, 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.

Loss from Discontinued Operations. Whitestone Uptown Tower, LLC’s financial condition and results of operations are presented as discontinued operations in our consolidated financial statements for periods presented before its deconsolidation on December 1, 2023. The loss on discontinued operations was $321 thousand for 2023 and $351 thousand for 2022.

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

Liquidity and Capital Resources

As of December 31, ~~2022~~2023, our unrestricted cash resources were $51.23 million.

Significant sources and uses of cash from continuing operations during ~~2022~~2023.

~~Sources~~• We used $1.2 million of cash: for operating activities from continuing operations. The Company had $1.1 million of cash inflows from working capital (receivables, prepaid expenses, accounts payable, security deposits) which partially offset cash operating losses. • Capital expenditures were $1.5 million, principally for deferred maintenance and life safety needs at our properties. • We made repayments of notes payable totaling $810 thousand.

• Cash from operating activities was approximately $1.5 million, which included $292 thousand from the primary components of our working capital (receivables, prepaid expenses, accounts payable, security deposits).

• We received $1.0 million of insured loss reimbursements for elevator damage at Uptown Tower prior to Whitestone’s termination of the management agreements for the Real Estate Assets.

Uses of cash:

• Capital expenditures were $1.8 million principally for elevator repairs at Uptown Tower and other deferred maintenance and life safety needs at our properties.

• We made repayments of notes payable totaling $760 thousand.

Page 37 of 63

Table of Contents

We expect our cash needs to increase significantly during 2023 as a result of the internalization of management and lack of significant cooperation in these efforts from Whitestone, the expenses of the ongoing litigation with Whitestone, and our addressing significant life safety and deferred maintenance issues at the Real Estate Assets that occurred during Whitestone’s management of the Real Estate Assets through Whitestone’s termination of its management activities for the Real Estate Assets in August 2022.

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 $576 thousand in 2023 for operating and administrative expenses incurred in 2023.

The reimbursements initially reported in our Quarterly Reports on Forms 10-Q for the periods ended March 31, 2022 and June 30, 2022 were substantially offset by reserves totaling $1.8 million because the amounts were disputed by Whitestone. In addition, while in control of the bank accounts, Whitestone refused to transfer the reimbursements as directed by the General Partner. As the manager responsible for all of our day-to-day operations prior to August 2022, Whitestone maintained financial records and access to all of our cash balances. The reserves were necessary then in recognition that significant efforts, including litigation, may have been necessary to collect these amounts.

Following Whitestone’s termination of the management agreements in August 2022, we internalized management of the Real Estate Assets. This includes maintenance of our financial records and direct access to all of our cash balances. Based on this and our rights to the full reimbursement as provided by the Pillarstone OP Amended and Restated Agreement of Limited Partnership, we reversed the reserves in August 2022.

Whitestone has notified us that they will contest some or all of these reimbursements. We intend to vigorously defend these reimbursements as they are permitted under provisions of the Pillarstone OP Amended and Restated Agreement of Limited Partnership.

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.

~~Page~~Whitestone 38Claim for Expenses. After we notified Whitestone of 63 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 December 31, 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 Item 3, “Legal Proceedings—Jointly Administered Bankruptcy Cases.”

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 ~~Item~~satisfaction 8of the prior mortgage loan. The plan of reorganization in the Whitestone Uptown Tower bankruptcy case, ~~“Financial~~providing ~~Statements~~for –the ~~Note~~sale 7of –Uptown ~~Debt”~~Tower and ~~our~~treatment ~~lease~~of ~~obligations~~claims, ~~are~~was ~~presented~~confirmed in ~~Item~~July 82024. We sold Uptown Tower in July 2025 for a purchase price of $20 million, ~~“Financial~~or ~~Statements—Note~~$17.3 4million –after ~~Leases~~deductions, closing costs and commissions and reimbursements to the seller, and paid off the American Bank, N.”A. indebtedness.

At December 31, 2022, Whitestone Uptown Tower, LLC, Pillarstone OP’s subsidiary that owns 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 is guaranteed by Whitestone OP. This mortgage is 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 collateralize this indebtedness.

As of December 31, 2022, the borrower was not in compliance with loan covenants requiring timely filing of financial information to the lender. In addition, the lender has asserted that Whitestone’s termination of the management agreement for Uptown Tower also caused an event of default under the loan agreement.

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.

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.

Table of Contents

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 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 have been 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.

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. We are holding approximately $13.6 million of the sale proceeds representing 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.

Page 40 of 63

Table of Contents

In addition to the mortgage loan, we have approximately $198,000 of convertible notes payable and corresponding accrued interest of approximately $141,000. 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. Any repayment of the convertible notes will be determined under our plan of liquidation and bankruptcy court proceedings.

Long Term Liquidity and Operating Strategies.

~~The~~Our ~~accompanying~~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 $2325.4 million as of December 31, ~~2022~~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 itus 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 ~~owns~~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 ~~are~~were dependent on cash generated by our ownership of the eight Real Estate Assets to meet our liquidity needs. ~~Historically~~Following the period covered by this report, we have ~~financed~~sold all of our ~~long-term~~Real ~~capital~~Estate ~~needs~~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 ~~acquisitions~~those of unsecured creditors subject to the Chapter 11 bankruptcy filings, aswhich ~~follows:~~were repaid in December 2025 and January 2026.

●

the Houston litigation discussed in Part I, Item 3 “Legal Proceedings—Houston Case” above; and

the Delaware litigation discussed in Part I, Item 3 “Legal Proceedings —Delaware Case” above;

●

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 December 31, 2022~~. Any new indebtedness may be at materially higher rates than ~~the~~previously ~~4.97%~~available ~~base~~to ~~rate~~us ofgiven ~~interest~~our ~~under~~present ~~the~~financial ~~loan agreement, plus the default rate of interest, which is 5% above the interest rate under the loan agreement~~condition. ~~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.

Page 41 of 63

Table of Contents

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.

At December 31, 2023, Whitestone Uptown Tower, LLC owed Pillarstone OP $3.7 million, net of a $377 thousand impairment loss recognized in 2023. This amount is reported as a receivable in our consolidated balance sheet and represents amounts expended by Pillarstone OP in support of Whitestone Uptown LLC over several years. We estimated the net amount Pillarstone OP is expected to recover after payment of Whitestone Uptown LLC’s third-party liabilities, operating expenses and bankruptcy administration costs.

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 9A. 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 December 31, ~~2022~~2023.

Management’s Report on Internal Control Over Financial Reporting

In connection with the preparation of our annual consolidated financial statements, management assessed the effectiveness of our internal control over financial reporting as of December 31, ~~2022~~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

●

Management has concluded that, based on applying the COSO criteria, as of December 31, ~~2022~~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.

We believe that the circumstances leading to this conclusion is a result of the lack of an orderly transition of the management services provided by Whitestone prior to its abrupt termination of our management agreements in August 2022.

Page 43 of 63

Table of Contents

The services provided by Whitestone under the management agreements were extensive and material to the operation of our 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 and have been difficult, expensive and time-consuming to separate. 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 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 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 disruption to our business 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.

As a result of Whitestone’s unwillingness to have a collaborative and planned transition, we were unable to timely file our annual and quarterly reports with the SEC.

This conclusion does not relate to periods prior to Whitestone’s termination of its management functions under the management agreements.

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 December 31, ~~2022~~2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Trustee Independence

Our common shares are currently quoted on the Expert Market of the OTC Markets Group. Accordingly, we are not subject to the rules of any national securities exchange that require a majority of a listed company’s trustees and specified committees of the board of trustees meet independence standards prescribed by such rules. However, the Board has affirmatively determined that each of Mr. Chookaszian and Ms. Jassem did not have a material relationship with Pillarstone Capital REIT that would interfere with the exercise of independent judgment and are “independent” as defined under NYSE MKT listing standards, applicable SEC rules and the standards prescribed by our declaration of trust.

Meetings and Committees of the Board

Our entire Board considers all major strategic decisions concerning our business. Our Board has also established committees so that certain matters can be addressed in more depth than may be possible at a meeting of the entire Board. Our Board has established a standing Nominating Committee, Audit Committee, and Management, Organization and Compensation Committee.

Audit Committee

We have a separately designated standing Audit Committee of the Board consisting of Mr. Chookaszian, who serves as Chairman and Ms. Jassem. Mr. Lambert served on the committee during 2022 and until his death in November 2024. Mr. Chookaszian also serves as the audit committee financial expert, as defined by the SEC. Each member of the Audit Committee satisfies the independence standards and financial literacy requirements set forth under NYSE MKT listing standards and the applicable rules of the SEC. The Audit Committee is directly responsible for engaging and reviewing the performance of our independent public auditors, oversees our accounting and financial reporting processes, considers and approves the range of audit and non-audit fees, reviews the adequacy of our internal accounting controls and procedures and resolves disagreements between management and our independent public auditors. Mr. Chookaszian also serves as the audit committee financial expert, as defined by the SEC. Each member of the Audit Committee satisfies the independence standards and financial literacy requirements set forth under NYSE MKT listing standards and the applicable rules of the SEC.

Nominating Committee

Mr. Lambert served as Chairman of the Nominating Committee during 2022 until his death in November 2024, with Mr. Chookaszian as a member. The Nominating Committee is responsible for identifying individuals qualified to become trustees and for evaluating potential or suggested trustee nominees. In order for an individual to qualify for nomination or election as a trustee, an individual, at the time of nomination, must have substantial expertise, experience or relationships relevant to the real estate business, which may include:

• commercial real estate experience; • an in-depth knowledge of and working experience in finance or marketing; • capital markets or public company experience; • university teaching experience in a Master of Business Administration or similar program; • experience as a chief executive officer, chief operating officer or chief financial officer of a public or private company; or • public or private company board experience.

•Additionally, an individual shall not have been convicted of a felony or sanctioned or fined for a securities law violation of any nature. The Nominating Committee in~~-depth~~ ~~knowledge~~its sole discretion will determine whether a nominee satisfies the foregoing qualifications or possesses such other characteristics as deemed necessary by the Nominating Committee. Though we have no formal policy addressing diversity, the Nominating Committee will seek to recommend nominees to the Board that represent a diversity of experience, gender, race, ethnicity and ~~working~~age. Any individual who does not satisfy the qualifications above is not eligible for nomination or election as a trustee. The Nominating Committee performs a preliminary evaluation of potential candidates primarily based on the need to fill any vacancies on our Board, the need to expand the size of our Board and the need to obtain representation in key disciplines and/or market areas. The Nominating Committee will seek to identify trustee candidates based on input provided by a number of sources, including the Nominating Committee members and other members of our Board. The Nominating Committee also has the authority to consult with or retain advisors to carry out its duties, though it has not used a third party to locate or evaluate potential candidates for trustee. Once a potential candidate is identified as one who fulfills a specific need, the Nominating Committee performs a full evaluation of the potential candidate. This evaluation includes reviewing the potential candidate’s background information, relevant experience, willingness to serve, independence and integrity. In connection with this evaluation, the Nominating Committee may interview the candidate in ~~finance~~person or ~~marketing;~~by telephone. After completing its evaluation, the Nominating Committee makes a recommendation to the full Board as to the individuals who should be nominated by our Board. Our Board elects nominees recommended by the Nominating Committee to fill vacancies on our Board and nominates the nominees for election by shareholders after considering the recommendations and a report of the Nominating Committee. Due to the small size of the Company and the Board, the Nominating Committee does not have a policy with regard to the consideration of any director candidates recommended by security holders. In addition to the above process, as part of an agreement approved by shareholders in June 2003, Mr. Mastandrea can appoint five trustees to the Board provided he remains as our Chairman or Chief Executive Officer. Mr. Mastandrea has not exercised this right.

Risk Oversight

It is the responsibility of the Board to approve a strategic business plan and select a chief executive officer to execute the strategic plan. While the Board is tasked with the responsibility to detect potential high level risks, management is tasked with managing risk on a daily basis. Where possible, management, in conjunction with the Board, has defined high level risk controls to help mitigate the most significant risks to the Company.

The Management, Organization, and Compensation Committee oversees risks relating to our executive compensation plans and arrangements. The Audit Committee oversees the risks of financial reporting and compliance, including cybersecurity attacks and loss of confidential information. The Nominating Committee oversees risk related to independence of the Board and potential conflicts of interests. Management reports any observed or potential risks to each committee and to the Board members at their meetings.

Code of Conduct and Ethics

Our Board has adopted a Code of Conduct and Ethics that applies to all officers, trustees and employees of Pillarstone, including our principal executive officer, principal financial officer, principal accounting officer, and any person performing similar functions. We have posted our Code of Conduct and Ethics on the Governance Documents page of our website at www.pillarstone-capital.org (previously www.pillarstone-capital.com). If we amend or grant any waiver from a provision of our Code of Conduct and Ethics, we will promptly disclose such amendment or waiver in accordance with and if required by applicable law, including by posting such amendment or waiver on our website at the address above.

Stock Trading Policies

Our Code of Conduct and Ethics provides that employees, officers and trustees may not buy or sell our shares when they are in possession of material, nonpublic information and are prohibited from passing on such information to others who might make an investment decision based on it. Employees, officers and trustees also may not trade in stocks of other companies about which they learn material, nonpublic information through the course of their employment or service. We have not adopted a specific practice or policy regarding the ability of our employees (including officers) or directors, or any of their designees, to purchase financial instruments (including prepaid variable forward contracts, equity swaps, collars, and exchange funds), or otherwise engage in transactions, that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our equity securities granted to the employee or director as part of the compensation of the employee or director or held, directly or indirectly, by the employee or director.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires the Company’s officers, trustees and persons who own more than 10% of our common shares to file reports of ownership and changes in ownership with the SEC. Officers, trustees and greater than 10% shareholders are required by regulation to furnish us with copies of all Section 16(a) forms they file. Based solely on review of the copies of Form 4s filed by trustees reporting share transactions, grants of restricted shares and options furnished to us, or written representations that no Annual Statements of Beneficial Ownership of Securities on Form 5 were required to be filed, we believe that for the fiscal year ended December 31, ~~2022~~2023, all Section 16(a) filing requirements applicable to our officers, trustees and greater than 10% shareholders were complied with, other than delinquent Form 3s to be filed by Bradford D. Johnson, Daniel P. Kovacevic and William Carter.

Item 11. Executive Compensation.

The Management, Organization and Compensation Committee (the “Committee”) administers the compensation program for the executive officers. The Committee is responsible for reviewing and recommending our compensation and employee benefit policies to the Board for its approval and implementation. The Committee reviews and recommends to the Board for approval the compensation for our Chief Executive Officer, including salaries, bonuses and grants of awards under our equity incentive plans. The Committee and the Board review and act upon proposals by the Chief Executive Officer to determine the compensation for other executive officers. The Committee, among other things, reviews and recommends to the Board employees to whom awards will be made under our equity incentive plans, determines the number of options to be awarded, and the time, manner of exercise and other terms of the awards. Equity awards, including options, are not granted in anticipation of the release of material non-public information, and the release of material non-public information is not timed on the basis of option or equity grant dates.

The intent of the compensation program is to align the executive’s interests with that of our shareholders, while providing incentives and competitive compensation for implementing and accomplishing our short-term and long-term strategic and operational goals and objectives.

Under SEC rules for smaller reporting companies, a related person transaction is any transaction or any currently proposed transaction in which the Company was or is to be a participant, the amount involved exceeds the lesser of (i) $120,000 or (ii) 1% of the average of the Company’s total assets at year end for the last two completed fiscal years, and in which any related person had or will have a direct or indirect material interest. A “related person” is a director, executive officer, or a more than 5% shareholder since the beginning of our last completed fiscal year, and their immediate family members.

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

On December 8, 2016, we entered into the Contribution Agreement with Pillarstone OP and Whitestone 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 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. Pursuant to the Contribution Agreement, Whitestone OP became the 81.4% limited partner of Pillarstone OP. The terms of the Contribution Agreement were determined through arm's-length negotiations, were recommended to the board of trustees by a special committee of the board of trustees consisting solely of disinterested trustees of the Company and were approved by the full board. As of December 31, ~~2022~~2023, Whitestone OP, the operating partnership of Whitestone REIT, owned approximately 81.4% of the total outstanding Class A units representing limited partnership interests in Pillarstone OP. We account for Whitestone OP’s interest in Pillarstone OP as a non-controlling interest in our consolidated financial statements.

In connection with our former management agreements with Whitestone TRS, Inc., an affiliate of Whitestone REIT and Whitestone OP, we paid $~~567 thousand and $~~359 thousand in ~~2021 and~~ 2022~~, respectively~~. Whitestone terminated the management agreements in August 2022. For further discussion regarding the management agreements, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview—Lawsuit and Termination of Management Agreements.”

Prior to the termination of the management agreements, during the ordinary course of business, we had transactions with Whitestone OP that included, but were not limited to, rental income, interest expense, general and administrative costs, commissions, and property expenses. Pillarstone OP received rental payments from Whitestone OP of $~~903 thousand and $~~461 thousand in ~~2021 and~~ 2022~~, respectively~~. Pillarstone OP made rental payments for its executive offices to Whitestone OP of $~~19 thousand and $~~11 thousand in ~~2021 and~~ 2022~~, respectively~~.

At December 31, ~~2022~~2023, Pillarstone OP owed interest payable of approximately $~~107~~137 thousand to trustees.

Mr. Mastandrea, our Chairman and former Chief Executive Officer, also served as the Chairman and Chief Executive Officer of Whitestone REIT until January 18, 2022, and beneficially owned approximately 3.6% of the outstanding equity in Whitestone REIT (when calculated in accordance with Rule 13d-3(d)(1) under the Exchange Act).

Mr. Dee, the Senior Vice President, Chief Financial Officer, and Secretary of the Company, also served as the Chief Operating Officer and Corporate Secretary of Whitestone REIT until February 9, 2022, and beneficially owned less than 1% of the outstanding equity in Whitestone REIT (when calculated in accordance with Rule 13d-3(d)(1) under the Exchange Act).

In addition, Mr. Lambert, a trustee of the Company, also served as a trustee of Whitestone REIT until May 12, 2023.

In January 2022, Whitestone REIT terminated, purportedly with cause, Mr. Mastandrea from his position as Chief Executive Officer of Whitestone REIT. In February 2022, Mr. Mastandrea filed suit against Whitestone REIT and certain of its trustees and officers in the District Court of Harris County, Texas, alleging claims relating to the termination of his employment and seeking up to $25 million in damages and equitable relief. This lawsuit is ongoing at the time of this report. In addition, Mr. Mastandrea is involved in ongoing divorce proceedings with Christine Krombeen Mastandrea, who was Whitestone’s Executive Vice President of Corporate Strategy at the time of Mr. Mastandrea’s termination, and was appointed as Whitestone REIT’s Chief Operating Officer shortly thereafter.

On February 9, 2022, Whitestone REIT terminated Mr. Dee as its Chief Operating Officer and Mr. Johnson as its Executive Vice president of Acquisitions and Asset Management. Both Mr. Dee and Mr. Johnson have filed suit against Whitestone REIT in the District Court of Harris County, Texas alleging claims relating to the termination of their employment and breach of their respective employment agreements.

While we are not involved in those proceedings, we believe that these developments may impact our relationship with Whitestone.

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 December 31, ~~2022~~2023, as follows:

Trustee	Face Amount		Accrued Interest		Convertible into common shares

Totals	$	197,780	$	~~140~~160,~~815~~608		~~254~~269,~~391~~263

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 ~~three~~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. ~~Any~~We ~~repayment~~repaid of the convertible notes ~~will~~pursuant beto ~~determined under~~ our plan of liquidation and bankruptcy court proceedings. in January 2026 in the following amounts:

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America. The consolidated financial statements of Pillarstone Capital REIT, as of December 31, 2022, were audited by other auditors whose report dated July 31, 2025, expressed an unqualified opinion on those consolidated financial statements.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company suffered a net loss from operations and negative cash flows from operations, each of which are factors that raise substantial doubt about its ability to continue as a going concern. Management’s plans to address these challenges are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Going Concern:

Due to factors such as the net loss for the year and negative cash flows from operations, the Company evaluated the need to include a going concern qualification in the financial statements. See discussion in Note 1.

Auditing management’s determination regarding the inclusion of a going concern qualification requires significant judgement given the fact that the Company uses management estimates of future revenues and expenses, as well as assumptions about future fundraising activity, which are not able to be substantiated.

To evaluate the appropriateness of the going concern qualification, we examined and evaluated the financial information, including management’s plans to mitigate the going concern qualification, and management’s disclosure on going concern.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of Pillarstone Capital REIT:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Pillarstone Capital REIT and subsidiaries (the “Company”) as of December 31, 2022 ~~and 2021~~, and the related consolidated statements of operations, changes in equity (deficit), and cash flows for ~~each of~~ the ~~years in the two-~~year ~~period~~ ended December 31, 2022, and the related notes and schedules (collectively referred to as the “Consolidated Financial Statements”). In our opinion, the Consolidated Financial Statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 ~~and 2021~~, and the results of its operations and its cash flows for ~~each of~~ the ~~years in the two-~~year ~~period~~ ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These Consolidated Financial Statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s Consolidated Financial Statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the Consolidated Financial Statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting.

Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the Consolidated Financial Statements. We believe that our audits provide a reasonable basis for our opinion.

Substantial Doubt about the Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company’s litigation, bankruptcy and subsequent sale of its real estate assets raises substantial doubt about the Company’s ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the Consolidated Financial Statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the Consolidated Financial Statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Impairment Assessment of Real Estate Assets

As described in Note 1 to the Consolidated Financial Statements, management reviews 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. Management determines if 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. Actual results could differ from estimates supporting the Company’s impairment analysis. If management’s analysis indicates an impairment, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. As of December 31, 2022, the Company had $47 million in real estate assets, net of accumulated depreciation, with no impairment recognized for the year ended December 31, 2022.

F-4

We identified management’s impairment assessment as a critical audit matter primarily because of the significant estimates involved in management’s impairment analysis, as these estimates resulted in audit procedures involving a high degree of auditor judgment and subjectivity and challenges in obtaining and evaluating audit evidence.

Our testing procedures to address this critical audit matter included the following:

■

obtaining an understanding of the Company’s internal control over financial reporting applicable to management’s impairment assessment, including controls pertaining to management’s estimates supporting the impairment analysis;

■

evaluating the methodology used by management in its impairment analysis; and

■

comparing the carrying value of the real estate assets as of December 31, 2022 to their subsequent sales prices.

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.

F-As 9a 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 ~~Table~~July 19, 2022, we received written notice that Whitestone TRS confirmed termination of ~~Contents~~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.

During this 30-day notice period, Whitestone did not provide the operation and financial database of our information, nor did Whitestone cooperate 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 and have been difficult, expensive and time-consuming to separate. As a result, Pillarstone was materially and adversely affected by Whitestone’s abrupt termination of the management agreements, 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. 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 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 disruption to our business and higher costs. In other cases, Whitestone obligated us to long-term contracts for essential services that we cannot easily replace.

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 challenges 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 claims 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.

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 prevents 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 argues that Whitestone’s material breaches of contract and fiduciary duty operate to discharge and/or excuse any obligation to perform under the redemption provisions of the Pillarstone OP Amended and Restated Agreement of Limited Partnership.

Whitestone indicated to us its intent to cause Whitestone OP to exercise its redemption right and stated publicly that it intends 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 have stated that a redemption request would not trigger the Rights Agreement, and our board of trustees has 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.

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

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 also brought as an adversary proceeding by Whitestone Uptown Tower, LLC in the Uptown Tower bankruptcy case described in “—Uptown Tower” below.

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 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 the Whitestone Uptown Tower, LLC bankruptcy case described under “—Uptown Tower” below.

The plan agent is entitled to receive compensation as a flat fee the amount of $10,000.00 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 $650.00 per hour for each additional hour of services.

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 collateralize this indebtedness.

As of December 31, 2022, 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 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.

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 have been informed that the agreement was not consummated, but Whitestone did send approximately $13.6 million to Rialto Capital Advisors, LLC pursuant to this arrangement.

This litigation 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. The registrant believes that the allegations in the Delaware lawsuit are without merit and intends to continue to vigorously defend against them. In addition, we intend to vigorously pursue the Texas action to seek damages from Whitestone due to its violations of the management agreements and fiduciary duties and to protect our shareholders from the further harms that Whitestone has indicated it intends to inflict on us and our shareholders. However, the outcomes of these lawsuits, including the timing of the final disposition of the lawsuits, are unpredictable and could result in substantial costs to us. As a result, future adverse rulings, settlements, or unfavorable developments could result in charges that could have a material adverse effect on the registrant’s business, results of operations or financial condition.

Following the period covered by this report, we sold Real Estate Assets under the Whitestone Uptown Tower, LLC plan of reorganization and the plan of liquidation for the other Pillarstone entities.

In October 2024, we sold 9101 LBJ Freeway for a purchase price of $5,753,000, or approximately $5.1 million after deductions, closing costs and commissions.

In October 2024, we sold Interstate 10 Warehouse for a purchase price of $8,400,000, or approximately $8.1 million after deductions, closing costs and commissions.

In February 2025, we sold Corporate Park Woodland II for a purchase price of $1,650,000, or approximately $1.56 million after deductions, closing costs and commissions.

In July 2025, we sold Uptown Tower for a purchase price of $20,000,000, or approximately $17.3 million after deductions, closing costs and commissions.

In July 2025, in a series of related transactions, we sold:

• Corporate Park Northwest for a purchase price of $8,500,000, or approximately $7.8 million after deductions, closing costs and commissions;

• Holly Hall Industrial Park for a for a purchase price of $7,650,000, or approximately $7.2 million after deductions, closing costs and commissions;

• Holly Knight for a purchase price of $4,750,000, or approximately $4.5 million after deductions, closing costs and commissions; and

• Westgate Service Center for a purchase price of $9,100,000, or approximately $8.6 million after deductions, closing costs and commissions.

The accompanying 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 $23.4 million as of December 31, 2022 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 owns 81.4% of Pillarstone OP as a non-controlling limited partner. 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. 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

F- 15

Table of Contents

● proceeds from the sales of our Real Estate Assets.

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. These consolidated financial statements present the Company’s consolidated financial condition and results of operations including those of a wholly owned subsidiary, operations of which were discontinued in 2002, and variable interest entities (“VIEs”) for which we are the primary beneficiary.

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.

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.

Cash and cash equivalents. We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Real estate. Land, buildings and improvements are recorded at cost. Expenditures related to the development of real estate are carried at cost.

Depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of 5 to 39 years for improvements and buildings. Tenant improvements are depreciated using the straight-line method over the life of the improvement or remaining term of the lease, whichever is shorter.

F- 16

Table of Contents

Unamortized Lease Commissions and Deferred Legal Cost. Leasing commissions and deferred legal cost are amortized using the straight-line method over the terms of the related lease agreements. Costs allocated to in-place leases whose terms differ from market terms related to acquired properties are amortized over the remaining life of the respective leases.

Prepaid expenses and other assets. Prepaid expenses and other assets include escrows established pursuant to certain mortgage financing arrangements for real estate taxes and property improvements.

Stock-based compensation. We account for employee stock-based compensation using the fair value method. Compensation cost for equity incentive awards is based on the fair value of the equity instrument generally on the date of grant and is recognized over the requisite service period. Forfeitures are recognized as they occur. The Company uses the Black-Scholes option pricing model to estimate the fair value of option awards. The Black-Scholes option pricing model requires the input of highly subjective assumptions including the expected stock price volatility of the Company’s common stock, the risk-free interest rate at the date of grant, the expected vesting term of the grant, expected dividends, and an assumption related to forfeitures of such grants. Changes in these subjective input assumptions can materially affect the estimated fair value of the option awards.

F-14

We file tax returns federally and in the state of Texas. Our returns for periods prior to ~~2018~~2021 are no longer subject to examination by tax authorities in these jurisdictions. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. If a tax position meets the “more likely than not” recognition criteria, accounting guidance requires the tax position be measured at the largest amount of benefit greater than 50% likely of being realized upon ultimate settlement. We record income tax related interest and penalties, if any, as a component in the provision for income tax expense.

Earnings (loss) per share – Basic earnings (loss) per share amounts are calculated by dividing income (loss) available to common shareholders by the weighted average number of common shares outstanding. Diluted earnings (loss) per share amounts are calculated by dividing income (loss) available to common shareholders by the weighted average number of common shares and common stock equivalents outstanding which are not antidilutive. Common stock equivalents represent shares issuable upon the assumed conversion of outstanding convertible notes and preferred shares and the assumed exercise of outstanding options.

Fair Value Measurements. We measure the fair value of financial instruments based on assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, a fair value hierarchy distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. In accordance with the fair value hierarchy, Level 1 assets/liabilities are valued based on quoted prices for identical instruments in active markets, Level 2 assets/liabilities are valued based on quoted prices in active markets for similar instruments, on quoted prices in less active or inactive markets or on other “observable” market inputs, and Level 3 assets/liabilities are valued based significantly on “unobservable” market inputs.

Our financial instruments consist primarily of cash, cash equivalents, accounts receivable, accounts and notes payable. The carrying value of cash, cash equivalents, accounts receivable and accounts payable are representative of their respective fair values due to their short-term nature. The fair value of our long-term debt instrument, ~~consisting~~which consisted of a fixed rate secured note, approximated its carrying amounts due to the near-term maturity of the instrument.

Concentration of Risk. Substantially all of our revenues are obtained from office and warehouse locations in the Dallas and Houston metropolitan areas.

We maintain cash accounts in major U.S. financial institutions. The terms of these deposits are on demand to minimize risk. The balances of these accounts sometimes exceed the federally insured limits, although no losses have been incurred in connection with these deposits.

Segment information. Our management historically has not differentiated by property types and therefore does not present segment information.

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 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 financial statements upon adoption.

F-15

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 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.

F-17

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.

On August 3, 2023, we received a notice of default and demand for payment of the mortgage debt. In the letter, the lender and specialty servicer stated that the December 8, 2016 transaction with Whitestone OP pursuant to the Contribution Agreement resulted in a change in control which did not meet the terms of the consent letter obtained at the time of the transaction. As such, the lender and specialty servicer consider that terms of the mortgage debt were breached effective December 8, 2016 and that an event of default has occurred since that date resulting in accrued interest at the default rate totaling approximately $6.5 million.

At December 31, 2022, the reported net equity in Whitestone Uptown Tower, LLC was $4.8 million.

As of December 31, 2022, the borrower was not in compliance with loan covenants requiring timely filing of financial information to the lender for mortgage loan.

Whitestone Uptown Tower, LLC, Pillarstone OP’s subsidiary that owns the Uptown Tower office building, is the borrower under a loan agreement. The Uptown Tower office building is subject to a mortgage under the loan agreement. Whitestone OP is the guarantor of this mortgage loan. The mortgage debt is guaranteed by Whitestone OP. This mortgage is an obligation of Whitestone Uptown Tower, LLC, a subsidiary included in our consolidated financial statements. Neither Pillarstone Capital REIT nor Pillarstone OP has any obligation or guarantee of this indebtedness nor do any of our other properties collateralize this indebtedness.

As of December 31, 2022, 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 has 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 do not have an alternate source of funds for the operation of Uptown Tower. However, when Whitestone learned of our negotiations with the special servicer 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. As of December 31, 2023, Rialto Capital Advisors, LLC held approximately $969 thousand under the cash sweep. The borrower had requested disbursements of capital and operating expenditures from the special servicer 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.

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.

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 December 1, 2023, Whitestone Uptown Tower, LLC, an indirect subsidiary of the registrant, 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 Whitestone REIT to address these matters in November 2023 with representatives of Whitestone REIT’s board of trustees 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, 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 have been informed that the agreement was not consummated, but Whitestone did send approximately $13.6 million to Rialto Capital Advisors, LLC.

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. 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 $141 thousand and $121 thousand as of December 31, 2022 and 2021, respectively.

9. Shareholders’ Equity

Operating partnership units. Substantially all of our business is conducted through Pillarstone OP, and we are the sole general partner. We own 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 December 31, 2022, 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.

F-Effective 24June 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.

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:

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.

11. Whitestone Uptown Tower, LLC’s Bankruptcy and Deconsolidation

With the bankruptcy filing, we lost the ability to control or manage Whitestone Uptown Tower, LLC because of the bankruptcy court trustee taking over effective control and day-to-day management of this subsidiary. As required under U.S. GAAP, we deconsolidated Whitestone Uptown Tower, LLC from our consolidated financial statements effective December 1, 2023, the date of its bankruptcy filing. As such, Whitestone Uptown Tower, LLC’s financial condition and results of operations are no longer presented in our consolidated financial statements after this date.

Prior to deconsolidation, Pillarstone OP made intercompany loans to Whitestone Uptown Tower, LLC and incurred liabilities related to certain intercompany charges. These were considered intercompany transactions and were eliminated in consolidation of Whitestone Uptown Tower, LLC. Subsequent to deconsolidation, these liabilities and receivables were no longer eliminated through consolidation, are considered related-party transactions and are recorded in our consolidated balance sheets at their estimated fair value. We estimated the net amount Pillarstone OP is expected to recover after payment of Whitestone Uptown Tower, LLC’s third-party liabilities, operating expenses and bankruptcy administration costs. At December 31, 2023, Whitestone Uptown Tower, LLC owed Pillarstone OP $3.7 million, which amount is reported as a receivable in our consolidated balance sheet, net of the recognized impairment loss of $377 thousand.

Whitestone Uptown Tower, LLC’s financial condition and results of operations for periods presented before its deconsolidation are presented as discontinued operations in our consolidated financial statements.

On August 18, 2022, Whitestone TRS ceased all managerial services without providing any transition services. Pillarstone has worked since that time to internalize the management of its Real Estate Assets and to continue to pursue its business without the management services provided by Whitestone TRS.F-24

F-Indemnification 28provisions 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 ~~Table~~reimbursement provisions have provided us with critical sources of ~~Contents~~cash and liquidity to maintain our operations.

We determined that Whitestone, as operational manager until August 2022 was not making appropriate reimbursement of the Company’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.

~~The reimbursements initially reported in our Quarterly Reports on Forms 10~~F-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. As the manager responsible for all day-to-day operations, Whitestone maintained financial records and access to all cash balances of the Company. The reserves were necessary then in recognition that significant efforts, including litigation, may have been necessary to collect these amounts.25

Following Whitestone’s termination of managerial services in August 2022, we internalized management of the Company. This includes maintenance of the Company’s financial records and direct access to all cash balances of the Company. Based on this and our rights to the full reimbursement as provided by the Amended and Restated Agreement of Limited Partnership, we reversed the reserves in August 2022.

Whitestone has notified us that they will contest some or all of these reimbursements. We intend to vigorously defend these reimbursements as they are permitted under provisions of the Amended and Restated Agreement of Limited Partnership dated December 8, 2016.

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. The amount due Whitestone OP for these expenditures, if any, has not been determined. If Pillarstone OP reimburses any amounts to Whitestone OP, the payment would reduce the Whitestone OP limited partner investment account.

15As of December 31, 2023, the Company believes that the allegations in these lawsuits are without merit and intends to continue to vigorously defend against them. ~~Subsequent~~However, ~~Events~~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.

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.

FOn 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, 31in 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 ~~Table of Contents~~ Filings.

~~The~~Uptown 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.Tower

On ~~January~~ 25December 1, ~~2024~~2023, Whitestone OPUptown ~~delivered~~Tower, ~~its~~LLC ~~notice~~filed a voluntary petition for relief under Chapter 11 of ~~redemption~~the United States Bankruptcy Code in the United States Bankruptcy Court for ~~all~~the ~~but~~Northern ~~one~~District of ~~its~~Texas OPin ~~Units~~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 for the Uptown Tower property. 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, the special servicer of the mortgage loan, 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 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 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 the Whitestone Uptown Tower, LLC bankruptcy case described under “—Uptown Tower” below.

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 collateralize this indebtedness.

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.

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.

The jointly administered bankruptcy cases proceeded under an an approved plan of liquidation. 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 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:

●

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

F-28

●

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:

the adversary proceeding commenced by Pillarstone OP in the jointly administered bankruptcy cases;

the Houston litigation discussed in Part I, Item 3 “Legal Proceedings—Houston Case”; and

the Delaware litigation discussed in Part I, Item 3 “Legal Proceedings —Delaware Case”;

●

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

In addition to the subsequent events and developments discussed in Notes 1 and 14, the Company reported the following subsequent events:
