Real Estate Portfolio Update

Community Centered PropertiesTM Portfolio Statistics:

As of June 30, 2018, Whitestone wholly owned 58 Retail Community Centered PropertiesTM with 4.9 million square feet of gross leasable area ("GLA"). Whitestone’s properties are located in Austin (4), San Antonio (3), Chicago (1), Dallas-Fort Worth (7), Houston (16) and the greater Phoenix metropolitan area (27). In addition to being business friendly, the Texas and Arizona markets are among the top in the country in terms of size, economic strength and population growth. Between 2017 and 2022, all of these cities are expected to experience significant population growth, led by Austin and Dallas-Fort Worth each at +9.7%, San Antonio at +8.6%, Houston at +8.0% and Phoenix at +6.6% (1). Whitestone believes that the Company’s properties in these markets are

located on the best retail corners embedded in affluent communities. The Company also owns a majority interest in and manages 14 properties containing 1.5 million square feet of GLA through its investment in Pillarstone Capital REIT Operating Partnership, L.P.

At the end of the second quarter, the Company's diversified tenant base in its wholly-owned properties comprised 1,308 tenants, with the largest tenant accounting for only 3% of annualized base rental revenues.

Through June 30, 2018, leasing volume was 632,108 square feet compared to 451,537 square feet in the prior year.

The Company's total operating portfolio occupancy stood at 91.5% at quarter end, up 170 basis points from 89.8% at June 30, 2017.

Accounting Treatment of Pillarstone OP

In November 2017, we received a comment letter from the Staff of the Division of Corporation Finance of the SEC (the “Staff”) relating to our Annual Report on Form 10-K for the year ended December 31, 2016. In their letter, the Staff requested that we provide them with an analysis to support our determination that Pillarstone OP is a variable interest entity (“VIE”) of which we are the primary beneficiary and that Pillarstone OP should be consolidated in our financial statements in accordance with GAAP. In response to the Staff’s comment, we provided the Staff with our analysis of our accounting and financial reporting obligations relating to our interest in Pillarstone OP. After communicating our analysis and conclusions to the Staff and responding to additional questions from the Staff relating to this matter, the Staff did not object to or otherwise take exception to our initial determinations at the time of the consummation of the Pillarstone OP contribution transactions in December 2016 but provided a verbal reminder that the determination of the primary beneficiary of a VIE should be continually reassessed, noting that the initial terms of our Management Agreements with respect to Pillarstone OP expired in December 2017, and suggesting that we consider pre-clearing future accounting treatment of Pillarstone OP with the Staff of the Office of the Chief Accountant (“OCA”).

In connection with the preparation and review of our financial statements for the quarter ended March 31, 2018, we concluded, in accordance with the Staff’s recommendation, and after consultation with our outside accounting advisors, that it would be prudent to seek the pre-clearance of the OCA of our proposed treatment of Pillarstone OP in our financial statements for such quarter. Accordingly, in April 2018, we submitted a letter to the OCA seeking their concurrence with our determinations that we maintained our status as the primary beneficiary of Pillarstone OP and, accordingly, should continue to consolidate Pillarstone OP in our financial statements for the quarter ended March 31, 2018 in accordance with GAAP. After further correspondence, including telephonic meetings between us, our advisors and the OCA, the OCA informed us that it objected to our conclusions that we were the primary beneficiary of Pillarstone OP and were required to consolidate it in our financial statements under the VIE accounting guidance since the contribution in December 2016 and during the subsequent periods. We and our independent registered public accounting firm respectfully disagreed with the OCA’s determination and made a formal appeal to the Chief Accountant of the SEC.

On July 30, 2018, the Chief Accountant of the SEC informed us that our formal appeal was denied and that the OCA objects to our consolidation of Pillarstone OP in our financial statements under the VIE accounting guidance since the contribution in December 2016. As a result, we should not have consolidated Pillarstone OP in our financial statements under VIE accounting guidance in our historical financial statements for the years ended December 31, 2016 and 2017 and the interim periods. After consideration of the OCA’s objection to our original accounting, we determined that the Pillarstone OP contribution agreements did not meet the requirements for derecognition of the underlying assets and we have revised our accounting treatment accordingly. The revised accounting treatment did not result in a material difference from the previous accounting.

The Company intends for all such forward-looking statements to be covered by the safe-harbor provisions for forward-looking statements contained in Section 27A of the Securities Act and Section 21E of the Exchange Act, as applicable. Such information is subject to certain risks and uncertainties, as well as known and unknown risks, which could cause actual results to differ materially from those projected or anticipated. Therefore, such statements are not intended to be a guarantee of our performance in future periods. Such forward-looking statements can generally be identified by the Company's use of forward-looking terminology, such as “may,” “will,” “plan,” “expect,” “intend,” “anticipate,” “believe,” “continue,” “goals” or similar words or phrases that are predictions of future events or trends and which do not relate solely to historical matters.

The following are some of the factors that could cause the Company's actual results and its expectations to differ materially from those described in the Company's forward-looking statements: the Company's ability to meet its long-term goals, its assumptions regarding its earnings guidance, including its ability to execute effectively its acquisition and disposition strategy, to continue to execute its development pipeline on schedule and at the expected costs, and its ability to grow its NOI as expected, which could be impacted by a number of factors, including, among other things, its ability to continue to renew leases or re-let space on attractive terms and to otherwise address its leasing rollover; its ability to successfully identify, finance and consummate suitable acquisitions, and the impact of such acquisitions, including financing developments, capitalization rates and internal rate of return; the Company’s ability to reduce or otherwise effectively manage its general and administrative expenses; the Company’s ability to fund from cash flows or otherwise distributions to its shareholders at current rates or at all; the Company’s ability to raise capital for working capital, acquisition or other uses on attractive terms or at all; the impact of the de-consolidation of Pillarstone OP on our historical and future financial statements, current adverse market and economic conditions; lease terminations or lease defaults; the impact of competition on the Company's efforts to renew existing leases; changes in the economies and other conditions of the specific markets in which the Company operates; economic, legislative and regulatory changes, including the impact of the Tax Cuts and Jobs Act of 2017; the success of the Company's real estate strategies and investment objectives; the Company's ability to continue to qualify as a REIT under the Internal Revenue Code of 1986, as amended; 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 (“SEC”) from time to time.

Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this press release.

Non-GAAP Financial Measures

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

FFO: Management believes that FFO is a useful measure of the Company's operating performance. The Company computes FFO as defined by NAREIT, which states that FFO should represent net income available to common shareholders (computed in accordance with GAAP) excluding gains or losses from sales of operating assets, impairment charges and extraordinary items, plus depreciation and amortization of operating properties, including the Company's share of unconsolidated real estate joint ventures and partnerships. FFO does not represent cash flows from operating activities determined in accordance with GAAP and should not be considered an alternative to net income as an indication of the Company's performance or to cash flow from operations as a measure of liquidity or ability to make distributions and service debt.

Management considers FFO a useful additional measure of performance for an equity REIT because it facilitates an understanding of the operating performance of its properties without giving effect to real estate depreciation and amortization, which assumes that the value of real estate assets diminishes predictably over time. Since real estate values have historically risen or fallen with market conditions, management believes that FFO provides a more meaningful and accurate indication of the Company's performance and useful information for the investment community to compare Whitestone to other REITs since FFO is generally recognized as the industry standard for reporting the operations of REITs.

Other REITs may use different methodologies for calculating FFO, and accordingly, the Company's FFO may not be comparable to other REITs. The Company presents FFO per diluted share calculations that are based on the outstanding dilutive common shares plus the outstanding OP units for the periods presented.

FFO Core: Management believes that the computation of FFO in accordance with NAREIT's definition includes certain non-cash and non-comparable items that affect the Company's period-over-period performance. These items include, but are not limited to, legal settlements, non-cash share-based compensation expense, rent support agreement payments received from sellers on acquired assets, acquisition costs, and proxy contest professional fees. In addition, the Company believes that FFO Core is a useful supplemental measure for the investing community to use in comparing the Company to other REITs as many REITs provide some form of adjusted or modified FFO. However, other REITs may use different adjustments, and the Company's FFO Core may not be comparable to the adjusted or modified FFO of other REITs.

NOI: Management believes that NOI is a useful measure of the Company's property operating performance. The Company defines NOI as operating revenues (rental and other revenues) less property and related expenses (property operation and maintenance and real estate taxes). Because NOI excludes general and administrative expenses, depreciation and amortization, involuntary conversion, interest expense, interest income, provision for income taxes, gain or loss on sale or disposition of assets and capital expenditures and leasing costs, 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. The Company uses NOI to evaluate its operating performance since NOI allows the Company to evaluate the impact of factors, such as occupancy levels, lease structure, lease rates and tenant base, have on the Company's results, margins and returns. In addition, management believes that NOI provides useful information to the investment community about the Company's 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 the Company's overall financial performance since it does not reflect general and administrative expenses, depreciation and amortization, involuntary conversion, interest expense, interest income, provision for income taxes, gain or loss on sale or disposition of assets, and the level of capital expenditures and leasing costs necessary to maintain the operating performance of the Company's properties. Other REITs may use different methodologies for calculating NOI, and accordingly, the Company's NOI may not be comparable to that of other REITs.
