WHITESTONE REIT

REPORTS Third QUARTER AND YEAR-TO-DATE 2025 RESULTS

Houston, Texas, October 29, 2025- Whitestone REIT (NYSE: WSR) (“Whitestone” or the “Company”) today announced its operating and financial results for the third quarter and year-to-date of 2025. Whitestone creates neighborhood center communities in its high-quality open-air shopping centers that it acquires, owns, manages, develops, and redevelops primarily in some of the largest, fastest-growing, high-household-income markets in the Sun Belt. For the three months ended September 30, 2025 and 2024, Net income attributable to common shareholders per diluted share was $0.35 and $0.15, respectively.

“Whitestone is solidly on track to deliver on its peer leading long-term Core FFO per share growth target of 5-7%. Operational excellence combined with the 2nd highest percentage of shop space within the peer group has enabled Whitestone to deliver compounded annual growth in excess of 5% for Core FFO per share since 2021. Today management is reiterating its intention to extend that track record. Whitestone has also moved its Green Street portfolio Trade Area Power (TAP) score up by the greatest percentage versus its peer set over the past 3 years as growth within Texas and Arizona pairs with Whitestone’s capital recycling program to enhance our property values and value for our shareholders.”

– Dave Holeman, Chief Executive Officer

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.

Factors that could cause actual results to differ materially from any forward-looking statements made in this Report include: the imposition of federal income taxes if we fail to qualify as a real estate investment trust (“REIT”) in any taxable year or forego an opportunity to ensure REIT status; uncertainties related to national, international, regional and local economic conditions, including impacts and uncertainty from trade disputes and tariffs on goods imported to the United States and goods exported to other countries; real estate risks, including fluctuations in real estate values and the general economic climate in local markets and competition for tenants in such markets; legislative or regulatory changes, including changes to laws governing REITs; adverse economic or real estate developments or conditions in Texas or Arizona, particularly in Austin, Houston, Dallas, San Antonio, Scottsdale and Phoenix in particular, including the potential impact of public health emergencies, on our tenants’ ability to pay their rent, which could result in bad debt allowances or straight-line rent reserve adjustments; our current geographic concentration in the Austin, Houston, Dallas, San Antonio, Scottsdale and Phoenix metropolitan area markets makes us susceptible to potential local economic downturns; increases in interest rates, including as a result of inflation, which may increase our operating costs or general and administrative expenses; natural disasters, such as floods and hurricanes, which may increase as a result of climate change may adversely affect our returns and adversely impact our existing and prospective tenants; increasing focus by stakeholders on environmental, social, and governance matters; financial institution disruptions; availability and terms of capital and financing, both to fund our operations and to refinance our indebtedness as it matures; decreases in rental rates or increases in vacancy rates; harm to our reputation, ability to do business and results of operations as a result of improper conduct by our employees, agents or business partners; litigation risks; lease-up risks, including leasing risks arising from exclusivity and consent provisions in leases with significant tenants; our inability to renew tenant leases or obtain new tenant leases upon the expiration of existing leases; risks related to generative artificial intelligence tools and language models, along with the potential interpretations and conclusions they might make regarding our business and prospects, particularly concerning the spread of misinformation; our inability to generate sufficient cash flows due to market conditions, competition, uninsured losses, changes in tax or other applicable laws; geopolitical conflicts, such as the ongoing conflict between Russia and Ukraine, the conflict in the Gaza Strip and unrest in the Middle East; the need to fund tenant improvements or other capital expenditures out of our operating cash flow; the risk that we are unable to raise capital for working capital, acquisitions or other uses on attractive terms or at all; and the ultimate amount we will collect in connection with the redemption of our equity investment in Pillarstone Capital REIT Operating Partnership LP (“Pillarstone” or “Pillarstone OP.”); and other factors detailed in the Company's most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and other documents the Company files with the Securities and Exchange Commission from time to time.

Non-GAAP Financial Measures

This release contains supplemental financial measures that are not calculated pursuant to U.S. generally accepted accounting principles (“GAAP”) including EBITDAre, FFO, Core FFO, NOI and net debt. Following are explanations and reconciliations of these metrics to their most comparable GAAP metric.

EBITDAre: The National Association of Real Estate Investment Trusts (“NAREIT”) defines EBITDAre as net income computed in accordance with GAAP, plus interest expense, income tax expense, depreciation and amortization and impairment write-downs of depreciable property and of investments in unconsolidated affiliates caused by a decrease in value of depreciable property in the affiliate, plus or minus losses and gains on the disposition of depreciable property, including losses/gains on change in control and adjustments to reflect the entity’s share of EBITDAre of the unconsolidated affiliates and consolidated affiliates with non-controlling interests. We calculate EBITDAre in a manner consistent with the NAREIT definition. Management believes that EBITDAre represents a supplemental non-GAAP performance measure that provides investors with a relevant basis for comparing REITs. There can be no assurance the EBITDAre as presented by the Company is comparable to similarly titled measures of other REITs. EBITDAre should not be considered as an alternative to net income or other measurements under GAAP as indicators of operating performance or to cash flows from operating, investing or financing activities as measures of liquidity. EBITDAre does not reflect working capital changes, cash expenditures for capital improvements or principal payments on indebtedness.

FFO: Funds From Operations: NAREIT defines FFO as net income (loss) (calculated in accordance with GAAP), excluding depreciation and amortization related to real estate, gains or losses from the sale of certain real estate assets, gains and losses from change in control, and impairment write-downs of certain real estate assets and investments in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity. We calculate FFO in a manner consistent with the NAREIT definition and also include adjustments for our unconsolidated real estate partnership.

Core Funds from Operations (“Core FFO”) is a non-GAAP measure. From time to time, we report or provide guidance with respect to “Core FFO” which removes the impact of certain non-recurring and non-operating transactions or other items we do not consider to be representative of our core operating results including, without limitation, default interest on debt of real estate partnership, extinguishment of debt cost, gains or losses associated with litigation involving the Company that is not in the normal course of business, and proxy contest costs.

Management uses FFO and Core FFO as a supplemental measure to conduct and evaluate our business because there are certain limitations associated with using GAAP net income alone as the primary measure of our operating performance. Historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate assets diminishes predictably over time. Because real estate values instead have historically risen or fallen with market conditions, management believes that the presentation of operating results for real estate companies that use historical cost accounting is insufficient by itself. In addition, securities analysts, investors and other interested parties use FFO as the primary metric for comparing the relative performance of equity REITs. FFO and Core FFO should not be considered as alternatives to net income or other measurements under GAAP, as an indicator of our operating performance or to cash flows from operating, investing or financing activities as a measure of liquidity. FFO and Core FFO do not reflect working capital changes, cash expenditures for capital improvements or principal payments on indebtedness. Although our calculation of FFO is consistent with that of NAREIT, there can be no assurance that FFO and Core FFO presented by us is comparable to similarly titled measures of other REITs.

NOI: Net Operating Income: Management believes that NOI is a useful measure of our property operating performance. We define NOI as operating revenues (rental and other revenues) less property and related expenses (property operation and maintenance and real estate taxes). Other REITs may use different methodologies for calculating NOI and, accordingly, our NOI may not be comparable to other REITs. Because NOI excludes general and administrative expenses, depreciation and amortization, deficit in earnings of real estate partnership, interest expense, interest, dividend and other investment income, provision for income taxes, gain on sale of properties, loss on disposal of assets, and includes NOI of real estate partnership (pro rata) and net income attributable to noncontrolling interest, it provides a performance measure that, when compared year-over-year, reflects the revenues and expenses directly associated with owning and operating commercial real estate properties and the impact to operations from trends in occupancy rates, rental rates and operating costs, providing perspective not immediately apparent from net income. We use NOI to evaluate our operating performance since NOI allows us to evaluate the impact that factors such as occupancy levels, lease structure, lease rates and tenant base have on our results, margins and returns. In addition, management believes that NOI provides useful information to the investment community about our property and operating performance when compared to other REITs since NOI is generally recognized as a standard measure of property performance in the real estate industry. However, NOI should not be viewed as a measure of our overall financial performance since it does not reflect the level of capital expenditure and leasing costs necessary to maintain the operating performance of our properties, including general and administrative expenses, depreciation and amortization, equity or deficit in earnings of real estate partnership, interest expense, interest, dividend and other investment income, provision for income taxes, gain on sale of properties, and gain or loss on sale or disposition of assets.

Same Store NOI: Management believes that Same Store NOI is a useful measure of the Company’s property operating performance because it includes only the properties that have been owned for the entire period being compared, and that it is frequently used by the investment community. Same Store NOI assists in eliminating differences in NOI due to the acquisition or disposition of properties during the period being presented, providing a more consistent measure of the Company’s performance. The Company defines Same Store NOI as operating revenues (rental and other revenues, excluding straight-line rent adjustments, amortization of above/below market rents, and lease termination fees) less property and related expenses (property operation and maintenance and real estate taxes), Non-Same Store NOI, and NOI of our investment in Pillarstone OP (pro rata). We define “Non-Same Stores” as properties that have been acquired since the beginning of the period being compared and properties that have been sold, but not classified as discontinued operations. Other REITs may use different methodologies for calculating Same Store NOI, and accordingly, the Company's Same Store NOI may not be comparable to that of other REITs.

Net debt: We present net debt, which we define as total debt net of insurance financing less cash plus our proportional share of net debt of real estate partnership, and net debt to pro forma EBITDAre, which we define as net debt divided by EBITDAre because we believe they are helpful as supplemental measures in assessing our ability to service our financing obligations and in evaluating balance sheet leverage against that of other REITs. However, net debt and net debt to pro forma EBITDAre should not be viewed as a stand-alone measure of our overall liquidity and leverage. In addition, our REITs may use different methodologies for calculating net debt and net debt to pro forma EBITDAre, and accordingly our net debt and net debt to pro forma EBITDAre may not be comparable to that of other REITs.

We rely on reporting provided to us by our third-party partners for financial information regarding the Company's investment in Pillarstone OP. Because Pillarstone OP financial statements as of and for the nine months ended September 30, 2024 have not been made available to us, we have estimated depreciation and amortization of real estate assets based on the information available to us at the time of this Report. On January 25, 2024, we exercised our redemption notice for substantially all of our investment in Pillarstone OP. As a result, our ownership no longer represents a majority interest.
