Forward-Looking Statements

The following discussion should be read in conjunction with our audited consolidated financial statements and the notes thereto in this Annual Report on Form 10-K.

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. We undertake no obligation to update or revise forward-looking statements to reflect changed assumptions, the occurrence of unanticipated events or changes to future operating results.

PART I

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, ~~2021~~2022, 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 ~~pink~~Expert ~~sheets~~Market under the symbol “PRLE”.

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, ~~2021~~2022, we owned 18.6% of the outstanding equity in Pillarstone OP and fully consolidate it on our financial statements.

On December 8, 2016, ~~Pillarstone~~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 ~~are~~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 a 18.6% valued at $4.1 million as of the date of the Contribution Agreement.

~~Pursuant~~ Page to6 ~~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) of Whitestone, 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. No Pillarstone OP units were purchased under the OP Unit Purchase Agreement. Pillarstone and Whitestone agreed to extend the filing of the shelf registration statement to the date that the Company closes a public equity offering. 63

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, ~~which~~processes, isand ~~fully~~systems ~~consolidated~~and onin ~~Pillarstone's~~some ~~financial~~cases, ~~statements~~third-party providers for services they sub-contracted to perform.

As ~~Competition~~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.

WeOn ~~compete~~July 19, 2022, we received written notice that Whitestone TRS confirmed termination of the management agreements for the ~~acquisition~~Real ofEstate ~~properties~~Assets. ~~and~~We ~~leasing~~had ~~spaces~~previously communicated to ~~tenants~~Whitestone ~~with~~REIT ~~many~~our ~~entities,~~plan ~~including,~~to ~~among~~internalize ~~others,~~the ~~publicly~~management ~~traded~~of ~~REITs,~~our ~~life~~Real ~~insurance~~Estate ~~companies~~Assets, ~~pension~~but ~~funds,~~we ~~partnerships~~had ~~and~~not ~~individual~~made ~~investors.

~~Employees~~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 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.

AsWithin days after the termination of ~~December 31,~~the ~~2021~~management agreements by Whitestone, we internalized management and began to manage the ~~Company~~Real Estate Assets and our business without an external management company. This process has ~~two~~involved ~~part~~commencing ~~time~~a ~~employees~~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.

~~Item~~Federal, 3state and local environmental laws and regulations regulate releases of hazardous or toxic substances into the environment. ~~Legal~~ ~~Proceedings~~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.

To assist with and expedite this process, we have retained accounting consultants to (i) recreate the accounting records, processes, and systems that Whitestone has not released in usable electronic format to us, and (ii) incorporate those records that we have received, and are continuing to sporadically receive, from Whitestone related to the Real Estate Assets and their management. In the meantime, the registrant is directly overseeing the maintenance and operations of the Real Estate Assets. In the course of doing so, we have confirmed that certain Real Estate Assets have deteriorated following significant deferred maintenance and neglect while under Whitestone’s management. We are working to address these deferred maintenance and other operating issues, and new issues dating back to Whitestone’s management emerge regularly.

OnBased ~~March 30~~upon issues, including those discussed in this report, we filed a lawsuit on September 16, 2022 in Harris County, ~~the~~Texas ~~closing~~against ~~price~~Whitestone and certain officers of ~~our~~Whitestone ~~Common~~REIT ~~Shares~~alleging, ~~reported~~among onother things, breach of the ~~Pink~~Pillarstone ~~Market~~OP ~~was~~limited ~~$1.31~~partnership ~~per~~agreement ~~share.~~and fiduciary duty and breach of the management agreements and seeking an accounting and reconciliation of amounts that may be owed to the registrant or Pillarstone OP.

~~Dividend~~In ~~Policy~~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.

~~Issuer~~Whitestone ~~Purchases~~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 ~~Equity~~the ~~Securities~~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.

~~The~~Based ~~Company~~on ~~did~~Whitestone’s performance under the management agreements and their public statements regarding its intentions to monetize its investment in Pillarstone OP, we do not ~~purchase~~believe ~~any~~that Whitestone’s actions in connection with the exercise of ~~its~~the ~~equity~~redemption ~~securities~~rights will respect the rights of the holders of our common shares. The Pillarstone OP limited partnership agreement expressly provides that in ~~2021~~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.

6We 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.

~~Item~~On 7July 17, 2023 and July 18, 2023, trial was held in the Delaware lawsuit. ~~Management'~~ 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. We disagree with the Delaware court’s ~~Discussion~~ruling and ~~Analysis~~are considering our options for appeal, subject to a final order being entered in the case, the outcome of ~~Financial~~various ~~Condition~~proceedings in the jointly administered bankruptcy cases described below and ~~Results~~the decision of ~~Operations~~the plan agent in the bankruptcy cases to pursue an appeal.

~~Overview~~ Page 10 of 63

~~The~~ Table ~~Company is a Maryland REIT engaged in investing in, owning and operating commercial properties. 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 real estate operating company, and (iii) joint venture investments. Substantially all of our business is conducted through our operating partnership Pillarstone OP. We are the sole general partner of Pillarstone OP. As of December 31, 2021, we owned approximately 18.6% of the outstanding equity in Pillarstone OP and we fully consolidate it on our consolidated financial statements.Contents

~~Brief~~In ~~History~~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.

~~Impact~~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 ~~COVID-19~~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.

~~The~~We ~~ongoing~~worked ~~COVID~~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-19controlling ~~pandemic~~limited ~~has~~partner. inWe believe the ~~past~~management ~~and~~functions ~~may~~as ~~continue~~operated toby ~~materially~~Whitestone were deeply integrated with Whitestone’s management functions for its own business and ~~adversely~~have ~~impact~~been difficult, expensive, and ~~disrupt~~time-consuming to separate, causing material adverse effects on our business, ~~financial~~income, ~~condition~~cash flow, results of operations, financial condition, liquidity and ~~cash~~prospects. ~~flows~~As a result, Whitestone did significant damage to us by its intentional actions. ~~Any~~In ~~future~~addition, ~~outbreak~~our litigation with Whitestone has been and is expected to continue to be expensive, lengthy, and disruptive to normal business operations.

7These material weaknesses arose in large part because of Whitestone’s abrupt termination in August 2022 of managerial services it 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.

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.

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 ~~read~~sure that we would recover the premises from the tenant promptly or from a trustee or debtor-in-possession ~~conjunction~~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 ~~consolidated~~premises. ~~financial~~If ~~statements~~a tenant becomes bankrupt, the federal bankruptcy code will apply and, ~~notes~~in ~~thereto~~some ~~appearing~~instances, ~~elsewhere~~may ~~herein~~restrict the amount and recoverability of our claims against the tenant.

~~Leasing~~We ~~Activity~~derive 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.

Also, the expense of ~~Operations~~ 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.

The difference was comprised of a decrease of approximately $343,000 in rental revenues, $155,000 in expense reimbursements, and $4,000 in other revenue and offset by a decrease of $104,000 in bad debt, which is classified as a reduction of revenue. The overall decrease was primarily due to lower occupancy, which was 3% lower as of December 31, 2021 compared to December 31, 2020.alternatives;

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 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.

~~Interest~~ Page ~~Rates~~14 ~~and~~of ~~Inflation~~63

~~The~~ Table ~~Company was not significantly affected by rising interest rates during the periods presented in this report due primarily to having 100%~~ of its debt with a fixed rate as of December 31, 2021. 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. Consequently, increases due to inflation, as well as ad valorem tax rate increases, generally do not have a significant adverse effect upon our operating results.Contents

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.

~~Revenue~~Risks ~~recognition. All~~Relating leases on our properties are classified as operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases. For the year ended December 31, 2021, we recognized a straight-line rent reserve adjustment decreasing rental revenue by approximately $23,000 for the conversion of one tenant to Financing

~~Acquired~~ Page ~~Properties~~15 ~~and Acquired Lease Intangibles. We allocate the purchase price~~ of the acquired properties to land, building and improvements, identifiable intangible assets and to the acquired liabilities based on their respective fair values at the time of purchase. Identifiable intangibles include amounts allocated to acquired out-of-market leases, the value of in-place leases and customer relationship value, if any. We determine fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends and specific market and economic conditions that may affect the property. Factors considered by management in our analysis of determining the as-if-vacant property value include an estimate of carrying costs during the expected lease-up periods considering market conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand and other economic conditions. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt. Due to COVID-19, we are carefully evaluating acquisitions, development and redevelopment opportunities on an individual basis.63

~~Depreciation. Depreciation~~ Table ~~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.~~Contents

~~Impairment.~~ We ~~review~~face ~~our~~risks ~~properties~~associated ~~for~~with ~~impairment at least annually or whenever events or changes in circumstances indicate that~~ the ~~carrying~~use ~~amount~~ of ~~the~~debt ~~assets,~~to ~~including~~fund ~~accrued~~acquisitions ~~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)~~developments, including ~~the~~refinancing ~~estimated residual value of the property, with the carrying cost of the property~~risk. If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. Management has determined that there has been no impairment in the carrying value of our real estate assets as of December 31, 2021.

We were not able to refinance the mortgage loan for our Uptown Tower property, ~~2020~~resulting in the filing of a bankruptcy petition for the borrower.

~~Item~~If 8principal 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. ~~Financial~~ ~~Statements~~In addition, we may rely on debt to fund a portion of our new investments such as our acquisition and ~~Supplementary~~development ~~Data~~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.

~~Item~~Our 9credit 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. ~~Changes~~ 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 ~~Disagreements~~future ~~with~~credit ~~Accountants~~facilities and debt instruments.

~~None~~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.

11Our 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.

~~Item~~The ~~9A. Controls~~incurrence ~~and~~of ~~Procedures.~~additional indebtedness could have adverse consequences on our business, such as:

~~None~~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.

16Inflation 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.

~~SIGNATURES~~Additionally, inflationary pricing may 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.

~~Pursuant~~Inflation may also cause increased volatility in financial markets, which could affect our ability to access the ~~requirements~~capital ofmarkets ~~Section~~or 13impact the cost or ~~15(d)~~timing ofat which we are able to do so.

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

~~POWER~~Turmoil OFin ~~ATTORNEY~~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.

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.

~~F-1~~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.

~~REPORT~~Legislative OFor ~~INDEPENDENT~~regulatory ~~REGISTERED~~action ~~PUBLIC~~with ~~ACCOUNTING~~respect ~~FIRM~~to tax laws and regulations could adversely affect us and our shareholders.

ToWe 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 ~~Board~~frequency and size of ~~Trustees~~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 ~~Shareholders~~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.

~~Pillarstone~~We ~~Capital~~are ~~REIT:~~subject to environmental laws and regulations.

~~Opinion~~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 ~~Consolidated~~contaminated ~~Financial~~site ~~Statements~~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.

~~Basis~~To ~~for~~the ~~Opinion~~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.

~~These~~ Page ~~Consolidated~~19 ~~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.63

We Table ~~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. Accordingly, we express no such opinion.Contents

~~Our~~Risks ~~audits~~Related ~~included performing procedures~~ to ~~assess~~ the ~~risks~~Ownership 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~~Common 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.Shares

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.

~~F-4~~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.

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 ~~accompanying~~additional ~~notes~~tax incurred at regular corporate rates could significantly reduce the cash flows. Furthermore, we are annot ~~integral~~required ~~part~~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 ~~consolidated~~U.S. ~~financial~~federal ~~statements~~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.

~~F-9~~We are subject to the reporting requirements of the federal securities laws, which can be expensive.

~~Pillarstone~~We ~~Capital~~are ~~REIT~~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.

~~Notes~~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 ~~Consolidated~~a ~~Financial~~decline ~~Statements~~in the price, if any, of our common shares.

~~December~~Our 31board of trustees has the authority to issue up to 450,000,000 ~~2021~~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.

1The 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.~~ORGANIZATION~~ 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.

~~Basis~~The SEC has adopted regulations which generally define a “penny stock” to be any equity security that has a market price of ~~Accounting~~less than $5. ~~Pillarstone's~~00 ~~financial~~per ~~records~~share ~~are~~or ~~maintained~~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 ~~accrual~~equity ~~basis~~security also would constitute a “penny stock.” As our common shares fall within the definition of ~~accounting~~penny ~~whereby~~stock, ~~revenues~~these ~~are~~regulations ~~recognized~~require ~~when~~the ~~earned~~delivery, prior to any transaction involving our common shares, of a risk disclosure schedule explaining the penny stock market and ~~expenses~~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 ~~recorded~~required ~~when~~to ~~incurred~~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.

~~Use~~Risks ofRelated ~~estimates. In order~~ to ~~conform~~Our with U.S. GAAP, management, in preparation of our consolidated financial statements, is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of December 31, 2021 and 2020, and the reported amounts of revenues and expenses for the years ended December 31, 2021 and 2020. Actual results could differ from those estimates. Significant estimates that we use 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. Actual results could differ from those estimates. Bankruptcy

We ~~determine~~These ~~fair~~risks value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends and specific market and economic conditions that may affect the property. Factors considered by management in our analysis of determining the as-if-vacant property value include ~~an estimate of carrying costs during the expected lease-up periods considering market conditions, and costs to execute~~ :

~~F-10~~• our ability to obtain bankruptcy court approval with respect to motions filed in the bankruptcy cases from time to time;

~~Pillarstone~~• ~~Capital~~our ~~REIT~~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;

~~Notes~~• our ability to ~~Consolidated~~engage ~~Financial~~in ~~Statements~~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;

~~December~~• ~~31,~~our ~~2021~~ability to negotiate and consummate our plan of liquidation and the Whitestone Uptown Tower plan of reorganization;

~~similar~~• ~~leases. In~~our ~~estimating~~ability ~~carrying~~to ~~costs~~develop, ~~management includes real estate taxes~~fund, ~~insurance~~ and ~~estimates of lost rentals at market rates during the expected lease-up periods, tenant demand and other economic conditions. Management also estimates costs to~~ execute ~~similar~~our ~~leases~~business ~~including~~plan; ~~leasing commissions, tenant improvements, legal~~ and other related expenses. Intangibles related to out-of-market leases and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt. Due to COVID-19, we are carefully evaluating acquisitions, development and redevelopment opportunities on an individual basis.

~~Depreciation. Depreciation~~• isour ~~computed~~ability ~~using the straight-line method over the estimated useful lives of 5~~ to 39continue ~~years~~as ~~for~~a ~~improvements~~going ~~and buildings~~concern. ~~Tenant improvements are depreciated using the straight-line method over the life of the improvement or remaining term of the lease, whichever is shorter.~~

~~Accrued~~ Page ~~Rents~~22 and Accounts Receivable. Included in accrued rents 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 including the impact of the COVID-19 pandemic on tenants’ businesses and financial condition. 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. For the years ended December 31, 2021 and 2020, we had an allowance for uncollectible accounts of approximately $538,000 and $398,000, respectively. For the years ended December 31, 2021 and 2020, we recorded an adjustment to rental revenue in the amount of approximately $138,000 and $242,000, respectively. Included in the adjustment to rental revenue for the years ended December 31, 2021 and 2020, was an adjustment of approximately $53,000, and $57,000, respectively, related to credit losses for the conversion of approximately four tenants to cash basis revenue as a result of our COVID-19 collectability analysis.63

~~Unamortized~~ Table ~~Lease Commissions and Loan Costs. Leasing commissions are amortized using the straight-line method over the terms~~ of the related lease agreements. Loan costs are amortized on the straight-line method over the terms of the loans, which approximates the interest method. 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.Contents

~~Revenue~~We ~~recognition. All leases on our properties~~ are ~~classified~~in ~~as operating leases, and~~ the ~~related~~process ~~rental income is recognized on a straight-line basis over the terms~~ of ~~the~~Chapter ~~related~~11 ~~leases. For~~reorganization ~~the~~cases ~~year~~under ~~ended December 31, 2021, we recognized a straight-line rent reserve adjustment decreasing rental revenue by approximately $23,000 for~~ the ~~conversion~~Bankruptcy ~~of one tenant to cash basis revenue as a result of our COVID-19 collectability analysis. For the year ended December 31~~Code, ~~2020,~~which wemay ~~recognized~~cause ~~a straight-line rent reserve adjustment decreasing rental revenue by approximately $51,000 for the conversion of four tenants to cash basis revenue as a result of~~ our ~~COVID-19~~common ~~collectability~~shares ~~analysis. Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable,~~ to ~~accrued~~decrease ~~rents and accounts receivable. Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues~~ in ~~the~~value ~~period~~or ~~the~~may ~~corresponding~~render ~~costs~~our ~~are~~common ~~incurred. We~~shares ~~combine lease and nonlease components in lease contracts, which includes combining~~ worthless.

~~F-11~~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. 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.

~~Pillarstone~~Operating ~~Capital~~in ~~REIT~~bankruptcy for a long period of time may harm our business.

~~Notes~~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 ~~Consolidated~~bankruptcy ~~Financial~~court ~~Statements~~protection, 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.

~~December~~So 31long as we remain under bankruptcy court protection, ~~2021~~we will be required to incur substantial costs for professional fees and other expenses associated with the administration of 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.

~~base~~Should ~~rent~~the ~~and~~time ~~recoveries~~that ~~into~~we aremain ~~single~~under ~~line~~bankruptcy ~~item,~~court ~~Rental~~protection be protracted, ~~within~~we ~~the~~may ~~consolidated~~also ~~statements~~need ofto seek new financing to fund operations.

~~Stock-based~~ Page ~~compensation.~~23 The Company accounts for stock-based compensation in accordance with ASC No. 718, "Compensation - Stock Compensation," which addresses the accounting for stock-based payment transactions in which an enterprise receives employee services in exchange for (a) equity instruments of the enterprise or (b) liabilities that are based on the fair value of the enterprise’s equity instruments or that may be settled by the issuance of such equity instruments. ASC No.718 generally requires that these transactions be accounted for using a fair-value-based method. The Company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards. 63

~~Income~~ Table taxes. Because we have not elected to be taxed as a REIT for federal income tax purposes, 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 provision for income taxes in the consolidated statements of operations and has not been separately stated due to its insignificance.Contents

~~The~~Item ~~Company evaluates potential uncertain tax positions on an annual basis in conjunction with the board of trustees and its tax accountants~~2. ~~Authoritative~~ ~~literature provides a two-step approach to recognize and measure tax benefits when realization of the benefits is uncertain~~Properties. The first step is to determine whether the benefit meets the more-likely-than-not condition for recognition and the second step is to determine the amount to be recognized based on the cumulative probability that exceeds 50%. Embedded in the effective tax rate for the years ended December 31, 2021 and December 31, 2020 are the tax effects of the Company's operating activities. For the year ended December 31, 2021, the Company's effective tax rate applied to its income before income taxes decreased in relation to the statutory rate as a result of income allocated to noncontrolling interest and increased in relation to the statutory rate primarily as a result of state income tax. For the year ended December 31, 2021, the Company's effective tax rate applied to its income before income taxes decreased in relation to the statutory tax rate primarily as a result of a change in the treatment of the gain on certain Real Estate Asset sales described below and income allocated to noncontrolling interest. Please refer to Note 15 (Income Taxes) to the accompanying consolidated financial statements for more information regarding the effective tax rate.

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.

On Page ~~December~~24 8, 2016, Pillarstone 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 are 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 a 18.6% valued at $4.1 million as of the date of the Contribution Agreement. 63

In Table ~~connection with the Contribution Agreement, on December 8, 2016, the Company, as the general partner~~ of Pillarstone OP, entered into an Amended and Restated Agreement of Limited Partnership of Pillarstone OP (as amended and restated (the “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.Contents

~~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,~~July ~~LTIP units are similar to the OP Units and will receive the same quarterly per-unit profit distributions as the OP Units.

~~5. REAL~~Delaware ~~ESTATE~~Case

AsOn 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 31 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 ~~owned~~Amended ~~eight~~and ~~commercial~~Restated ~~properties~~Agreement inof ~~the~~Limited ~~Dallas~~Partnership, and ~~Houston~~that ~~metropolitan~~we ~~areas~~breached ~~comprised~~our fiduciary duties as general partner of ~~approximately~~Pillarstone ~~0.9~~OP ~~million~~to ~~square~~Whitestone ~~feet~~OP and breached the implied covenant of ~~gross~~good ~~leasable~~faith ~~area~~and fair dealing under the Amended and Restated Agreement of Limited Partnership.

~~6. ACCRUED~~Based ~~RENTS~~upon ~~AND~~various ~~ACCOUNTS~~issues, ~~RECEIVABLE~~including those discussed in this report, ~~NET~~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.

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.

~~F-14~~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.

~~December~~Based 31on Whitestone’s performance under the management agreements and their public statements regarding their intentions for their interest in Pillarstone, ~~2021~~we did not believe that Whitestone’s actions in connection with the exercise of the redemption rights would respect the rights of the holders of our common shares. The Pillarstone OP Amended and Restated Agreement of Limited Partnership expressly provides that in the event of a conflict between the interests of the limited partners (Whitestone OP as the sole limited partner) and our shareholders, we shall act in the interests of our shareholders, and we shall not be liable for monetary or other losses sustained, liabilities incurred or benefits not derived by the limited partners in connection therewith.

On 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. We disagree with the Delaware court’s ruling and are considering our options for appeal, subject to a final order being entered in the case, the outcome of various proceedings in the jointly administered bankruptcy cases described below and the decision of the plan agent in the bankruptcy cases to pursue an appeal.

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.

11In 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] [. ~~SHAREHOLDERS'~~ ~~EQUITY~~. .] 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.

~~F-16~~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.

~~Pillarstone~~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 ~~REIT~~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.

~~Notes~~On October 24, 2023, the lender delivered a notice of foreclosure sale to ~~Consolidated~~the ~~Financial~~borrower ~~Statements~~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 311, ~~2021~~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.

~~F-17~~Market Information

~~Pillarstone~~There ~~Capital~~is ~~REIT~~no established public trading market for the common shares. Only a sporadic and highly limited market exists for our common shares, particularly as we have been delinquent in filing our annual and quarterly reports under the Exchange Act. There is no assurance that a regular trading market will develop, or if developed, that it will be sustained. Our common shares are not on an exchange but are quoted on the Expert Market of the OTC Markets Group (the "Expert Market") with the symbol "PRLEQ".

~~Notes~~The tonumber ~~Consolidated~~of ~~Financial~~holders ~~Statements~~of record of our common shares was 101 as of July 21, 2025, and we estimate we have approximately 250 beneficial holders of common shares as of that date. As of July 21, 2025, we had 657,084 common shares of beneficial interest outstanding.

The following table sets forth the quarterly high and low sale prices per share of our common shares for the years ended December 31, 2022 and 2021 as reported on the Pink Market, where the common shares were quoted as of those dates. The quotations shown represent inter-dealer prices without adjustment for retail markups, markdowns or commissions, and may not reflect actual transactions.

Each of the trustees of Pillarstone, who were members of the board of trustees in September 2006, signed a restricted share agreement with Pillarstone, dated September 29, 2006, to receive a total of 12,500 restricted Class C Preferred Shares in lieu of receiving fees in cash for service as a trustee for the two years ending September 29, 2008. The restrictions on the Class C Preferred Shares were to be removed upon the latest to occur of a public offering by Pillarstone sufficient to liquidate the Class C Preferred Shares, an exchange of Pillarstone's existing shares for new shares, or September 29, 2008. These shares were fully amortized by the original date in 2008. On October 22, 2018, a trustee forfeited his Class C Preferred Shares as a result of his resignation from our board of trustees.

Our Class A Cumulative Convertible Preferred Shares ("Class A Preferred Shares") are quoted on the Expert Market with the symbol "PRLPQ".

On Page ~~June~~ 30, ~~2003, our shareholders approved the issuance~~ of an agreement to issue additional Common Shares to Paragon Real Estate Development, LLC of which Mr. Mastandrea is the managing member, and Mr. Dee is a member. In September 2006, Pillarstone amended this agreement to include each of the trustees to the agreement so that if a trustee brings a new transaction to Pillarstone, he would receive additional Common Shares of Pillarstone in accordance with a formula in the agreement. In January 2016, the non-employee trustees and Mr. Mastandrea agreed to make this agreement for only non-employee trustees. The agreement is intended to serve as an incentive for our trustees to increase the asset base, net operating income, funds from operations, and share value of Pillarstone. The exact number of Common Shares that would be issued will be calculated in accordance with a formula in the agreement based on future acquisition, development or redevelopment transactions. Any of these transactions would be subject to approval by the members of our board of trustees who are not receiving the additional Common Shares. We would issue our Common Shares only upon the closing of a transaction. The maximum number of Common Shares a trustee may receive under the additional contribution agreement is limited to a total value of $26 million based on the average closing price of our Common Shares for 30 calendar days preceding the closing of any acquisition transaction. The Common Shares will be restricted until we achieve the five years-year pro forma income target 63

We own approximately 18.6% of Pillarstone Capital REIT Operating Partnership LP (“Pillarstone OP”) and serve as its general partner. Substantially all of our operations and activities are conducted for ~~outstanding~~the ~~stock~~benefit ~~options:~~of and through Pillarstone OP. As the general partner of Pillarstone OP, we have the exclusive power to manage and conduct the business of Pillarstone OP, subject to certain customary exceptions.

Future real estate opportunities 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 real estate operating company, (iii) sales of existing properties, (iv) redevelopment of existing properties, and (v) joint venture investments. There can be no assurance that we will be able to close additional transactions. Even if our management is successful in closing additional transactions, investors may not value the transactions or the Company in the same manner as we do, and investors may not value the transactions as they would value other transactions or alternatives. Failure to obtain additional sources of capital will materially and adversely affect the Company’s ability to continue operations, as well as its liquidity and financial results.

(1) The aggregate intrinsic value is calculated as approximately the difference between the weighted average exercise price of the underlying awards and the Company’s estimated current fair market value at December 31, 2021. Because the weighted average exercise price exceeds fair market value at December 31, 2021, there is no aggregate intrinsic value for the options.History

~~Shareholders'~~Pillarstone ~~Rights~~was ~~Plan~~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.

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 the Operating Partnership 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 the Operating Partnership’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.63

If Table ~~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 Contents

FIn 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-19to-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.

~~Pillarstone~~On ~~Capital~~July ~~REIT~~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.”

~~Notes~~Prior to ~~Consolidated~~receiving ~~Financial~~the ~~Statements~~termination notice, we had anticipated an orderly transition of the management of the Real Estate Assets over an appropriate timeframe.

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 3127, 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.

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.

14On July 21, 2022, Whitestone OP filed a Motion to Preserve the Status Quo requesting broad restrictions on our ability to conduct our business, including buying properties, enforcing the Rights Agreement, incurring expenses, or engaging in transactions. ~~DIVIDENDS~~ ~~AND~~The ~~DISTRIBUTIONS~~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.

NoRepresentatives ~~cash~~of ~~distributions~~our ~~were~~board ~~declared~~of ~~during~~trustees ~~2021~~attempted ~~and~~to ~~2020~~initiate discussions to settle these matters in August 2022 with ~~respect~~representatives of Whitestone’s board of trustees to ~~common~~avoid a prolonged, expensive legal fight. However, Whitestone was not open to settling these matters at that time or ~~preferred~~the ~~shares~~other various times since August 2022 we attempted to initiate discussions to resolve these matters.

15Whitestone 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. ~~INCOME~~ ~~TAXES~~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.

~~The~~Based ~~Company~~on ~~follows~~Whitestone’s performance under the ~~provisions~~management ofagreements ~~ASC~~and ~~Topic~~their ~~740~~public ~~which~~statements ~~provides~~regarding their intentions for ~~recognition~~their interest in Pillarstone, we did not believe that Whitestone’s actions in connection with the exercise of ~~deferred~~the ~~tax~~redemption ~~assets~~rights would respect the rights of the holders of our common shares. The Pillarstone OP Amended and ~~liabilities~~Restated ~~for~~Agreement ~~deductible~~of ~~temporary~~Limited ~~timing~~Partnership ~~differences,~~expressly ~~net~~provides that in the event of a ~~valuation~~conflict ~~allowance~~between ~~for~~the ~~any~~interests ~~asset~~of ~~for~~the ~~which~~limited itpartners is(Whitestone ~~more-likely-than-not~~OP ~~will~~as the sole limited partner) and our shareholders, we shall act in the interests of our shareholders, and we shall not be ~~realized~~liable infor monetary or other losses sustained, liabilities incurred or benefits not derived by the ~~Company’s~~limited ~~tax~~partners ~~return~~in connection therewith.

~~Pillarstone~~On ~~Capital~~July ~~REIT~~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. We disagree with the Delaware court’s ruling and are considering our options for appeal, subject to a final order being entered in the case, the outcome of various proceedings in the jointly administered bankruptcy cases described below and the decision of the plan agent in the bankruptcy cases to pursue an appeal.

~~Notes~~The Delaware court declared the Rights Agreement unenforceable against Whitestone, permitted Whitestone OP to ~~Consolidated~~tender ~~Financial~~a ~~Statements~~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.

~~December~~On 31January 25, ~~2021~~2024, Whitestone OP delivered its notice of redemption for all but one of its OP Units.

On Page ~~December~~35 ~~8, 2016, the Company entered into the Contribution Agreement with Pillarstone OP and Whitestone OP, both~~ of which are related parties, resulting in the contribution of an equity ownership interest in Pillarstone OP to the Company valued at $4,121,312 and representing approximately 18.6% of the outstanding equity in Pillarstone OP. The terms of the Contribution Agreement were determined through arm's-length negotiations and 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 approved by the full board. 63

As Table of December 31, 2021, Mr. James C. Mastandrea was the Chairman and Chief Executive Officer of Whitestone REIT and also serves as the Chairman and Chief Executive Officer of Pillarstone Capital REIT and beneficially owns approximately 66.7% of the outstanding equity in Pillarstone Capital REIT (when calculated in accordance with Rule 13d-3(d)(1) under the Exchange Act of 1934, as amended (the “Exchange Act”)).

No Pillarstone OP units were purchased under the OP Unit Purchase Agreement. 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, on December 8, 2016, the Company and Pillarstone OP entered into a Tax Protection Agreement (the “Tax Protection Agreement”) with Whitestone OP pursuant to which Pillarstone OP agreed to indemnify Whitestone OP for certain tax liabilities resulting from its recognition of income or gain prior to December 8, 2021 if such liabilities result from a transaction involving a direct or indirect taxable disposition of all or a portion of the Property or if Pillarstone OP fails to maintain and allocate to Whitestone OP for taxation purposes minimum levels of liabilities as specified in the Tax Protection Agreement, the result of which causes such recognition of income or gain and Whitestone incurs taxes that must be paid to maintain its REIT status for federal tax purposes. As of December 31, 2021 the Tax Protection Agreement has expired.

We recognized a loss on disposal of fixed assets of $67 thousand in the 2022 period as compared with $1 thousand in the 2021 period, which is included in other expenses. We expect our operating and other expenses 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.

~~Pillarstone~~Our ~~Capital~~effective ~~REIT~~tax rate for the years ended December 31, 2022 and 2021 was 14% and 0%, 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.

OnSources ~~April 3, 2006, the board~~ of trustees authorized modifications to Mr. Mastandrea’s employment agreement. The modification agreement allows Mr. Mastandrea to devote time to other business and personal investments while performing his duties for Pillarstone. The original employment agreement with Mr. Mastandrea provides for an annual salary of $60,000 effective as of March 4, 2003. The initial term of Mr. Mastandrea’s employment is for two years and may be extended for terms of one year. Mr. Mastandrea’s base annual salary may be adjusted from time to time, except that the adjustment may not be lower than the preceding year’s base salary. The employment agreement provides that Mr. Mastandrea will be entitled to base salary and bonus at the rate in effect before any termination for a period of three years in the event that his employment is terminated without cause by us or for good reason by Mr. Mastandrea. Effective September 29, 2006, in lieu of an annual salary of $100,000 and to conserve cash, Mr. Mastandrea agreed to receive 44,444 Class C Preferred Shares for his services as an officer of Pillarstone through September 29, 2008. The shares were fully amortized by the original date in 2008.:

~~Pillarstone~~We ~~Capital REIT~~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.

~~Schedule~~Expense IIReimbursements. -Under ~~Valuation~~the Pillarstone OP Amended and ~~Qualifying~~Restated ~~Accounts~~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.

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.

~~F-26~~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.

~~Pillarstone~~The ~~Capital~~reimbursements ~~REIT~~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.

~~Schedule~~Following ~~III~~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 ~~Accumulated~~direct ~~Depreciation~~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.

~~December 31,~~Whitestone ~~2021~~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.

~~Schedule~~Whitestone ~~III~~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 ~~Accumulated~~2018 ~~Depreciation~~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.

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.

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

~~(2) The~~On ~~aggregate~~August ~~cost~~3, 2023, we received a notice of ~~real~~the ~~estate~~default ~~(in~~of ~~thousands)~~the mortgage loan from counsel for ~~federal~~the ~~income~~lender ~~tax~~and ~~purposes~~Rialto isCapital ~~$56~~Advisors,~~017~~ 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.

~~(3) This~~In ~~property~~the ~~secures~~default anotice, ~~$15~~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] [.~~0 million~~ ~~mortgage~~. ~~note~~. ] 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.

~~F-28~~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. 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.

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

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

The plan of reorganization in the bankruptcy case, providing for the sale of Uptown Tower and treatment of claims, was confirmed in July 2024. We sold Uptown Tower in July 2025 for a purchase price of $20 million, or $17.3 million after deductions, closing costs and commissions and reimbursements to the seller, and paid off the American Bank, N.A. indebtedness. 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 accompanying financial statements have been prepared assuming that we will continue as a going concern. We have incurred significant losses since the year ended December 31, 2020 and have an accumulated deficit of approximately $23.4 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 it 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 are 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

•

proceeds from the sales of our Real Estate Assets.

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.

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 higher rates than the 4.97% base rate of interest under the loan agreement, plus the default rate of interest, which is 5% above the interest rate under the loan agreement. For example, the mortgage loan with American Bank, N.A. that replaced the prior loan for Uptown Tower bears interest at the WSJ Prime Rate (as defined in the loan agreement) plus 7.5%. If we are not able to incur indebtedness on favorable terms to us, our business, financial condition, results of operations, or cash flows could be materially adversely affected.

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.

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.

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, based on criteria established in the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO criteria”).

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

●

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

●

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

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

A copy of each charter is available to shareholders free of charge upon written request to the Company’s Secretary at: Pillarstone Capital REIT, Attention: Secretary, 19407 Park Row, Suite 140, Houston, Texas 77084.

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.

Page 49 of 63

Table of Contents

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 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 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 person or 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. 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, 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.

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.

Compensation of Named Executive Officers

James C. Mastandrea did not receive any compensation for serving as our Chief Executive Officer, President and Chairman during the years ended December 31, 2022 and December 31, 2021. John J. Dee did not receive any compensation for serving as our Senior Vice President, Chief Financial Officer, and Corporate Secretary during the years ended December 31, 2022 and December 31, 2021.

Restricted Share Agreements

Effective June 30, 2003, we issued 696,078 preferred shares valued at approximately $2.4 million to Messrs. Mastandrea and Dee pursuant to separate restricted share agreements for their services at that time as executive officers of the Company. On June 30, 2003, 534,668 preferred shares were converted at a factor of 0.305 into 163,116 common shares. Under the restricted share agreement for each of Mr. Mastandrea and Mr. Dee, the restricted shares vest upon the later of the following dates:

●

the date our gross assets exceed $50.0 million, or

●

50% of the restricted shares on March 4, 2004; 25% of the shares on March 4, 2005; and the remaining 25% of the shares on March 4, 2006.

The Company has not vested any of the above shares. Even though the Company’s gross assets exceed $50 million, when considering its 18.6% ownership of Pillarstone OP, the Company’s effective ownership of gross assets is less than $50 million.

The number of common shares and the conversion factor have been revised to reflect the 1-for-75 reverse split of the common shares that occurred in July 2006.

Compensation of Trustees

During 2020, the Management, Organization, and Compensation Committee recommended to the Board, and the Board approved, paying an annual trustee fee of $30,000 to each non-employee trustee in common shares from the 2016 Equity Plan approved by shareholders in 2016, with each trustee having the option to receive up to 50% in cash and the balance in common shares. Due to the Status Quo Order issued by the Court of Chancery of the State of Delaware in the Delaware lawsuit, Mr. Chookaszian, Ms. Jassem, and Mr. Lambert could not be paid in common shares. Mssrs. Dee and Mastandrea became non-employee trustees in July 2022. As of the date of this report, we have not awarded or accrued any compensation to either Mr. Dee or Mr. Mastandrea in their capacities as non-employee trustees but may do so in the future.

Accordingly, the trustee fees of $30,000 each were accrued in 2022 but not paid. The non-employee trustees earned, but were not paid, trustee fees as follows:

Name	Fees earned or paid in cash ($)			Total ($)
Dennis H. Chookaszian	$	60,000.00	(1)	$	60,000.00

Includes fees for service of special committees established by the Board. For the special committee to analyze the Rights Agreement. Ms. Jassem served as chair of the special committee and earned $40,000 during 2022 for her services of which $20,000 was paid, and Mr. Chookaszian served as a member of the special committee and earned $30,000 during 2022 for his services of which $15,000 was paid.

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, 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, Pillarstone OP owed interest payable of approximately $107 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).

Table of Contents

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, as follows:

Trustee	Face Amount		Accrued Interest		Convertible into common shares
Dennis H. Chookaszian	$	28,888	$	20,570		37,158
Daniel G. DeVos	$	47,780	$	34,022		61,459
Paul T. Lambert	$	51,112	$	36,380		65,734
James C. Mastandrea	$	52,224	$	37,186		67,175
John J. Dee	$	17,776	$	12,657		22,865
Totals	$	197,780	$	140,815		254,391

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 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 repayment of the convertible notes will be determined under our plan of liquidation and bankruptcy court proceedings.
