Houston, Texas, May 5, 2014 - Whitestone REIT (NYSE: WSR - “Whitestone” or the “Company”), a fully integrated real estate company that owns, re-develops, leases, manages, and operates Community Centered Properties^TM, announced its financial results for the first quarter of 2014.

"Whitestone's well positioned portfolio of value-add Community Centered Properties^TM and the momentum of our ongoing leasing efforts in our high-growth markets of Arizona and Texas continues to drive meaningful per share increases in our key cash flow and earnings metrics," said James C. Mastandrea, Whitestone’s Chairman and Chief Executive Officer. Mastandrea added, "Leasing, redevelopment and growth from acquisitions will continue to drive our growth as we strive to attain an industry leading valuation multiple on an FFO per share basis.” Mastandrea concluded, “We will commence two developments on land we currently own and expect that this will provide us with additional inventory in 2015.”

Financial Results: First Quarter 2014 Compared to First Quarter 2013

• Funds From Operations ("FFO") Core increased 55%, or approximately $2.5 million, to $7.0 million from $4.5 million.

• FFO Core per diluted common share and Operating Partnership ("OP") unit was $0.31, as compared to $0.26 per diluted common share and OP unit for the same period of 2013. FFO Core excludes non-cash share-based compensation expense related to the expected vesting of restricted share and unit grants of $0.4 million, or $0.02 per diluted common share and OP unit in both periods. FFO Core also excludes acquisition expenses of $0.1 million in both periods and includes rental support payments of $0.1 million in 2014.

• FFO increased 59% to $6.4 million, or $0.28 per diluted common share and OP unit as compared to $4.0 million, or $0.23 per diluted common share and OP unit.

• Net Income was $2.4 million or $0.11 per diluted common share as compared to $1.0 million, or $0.06 per diluted common share in the prior year.

• Total revenues increased 28% to $17.8 million compared to $13.9 million.

• Property net operating income ("NOI") increased by 31% to $11.8 million as compared to $9.0 million.

• Same-store NOI growth improved 3.2% or $0.3 million.

Leasing Activity

The leasing team signed 113 leases totaling 232,000 square feet in new, expansion, and renewal leases in the first quarter of 2014 as compared to 71 leases totaling 131,000 square feet in the first quarter of 2013. The average lease size in the first quarter of 2014 was 2,594 square feet with the total lease value added increasing 6.5% to $11.5 million from the fourth quarter of 2013.

The Company’s total occupancy was 85.8% as of the end of the first quarter 2014, a 1.8% increase over the prior year, and down 1.0% from the prior quarter. The physical occupancy of the Operating Portfolio, which excludes new acquisitions and properties that are undergoing significant redevelopment or re-tenanting, was 86.1% as of March 31, 2014, up 0.6% from the prior year and down 2.0% from the previous quarter. The impact on occupancy from the previous quarter is primarily a result of re-tenanting in the Company's Houston market.

Balance Sheet and Liquidity

As of March 31, 2014, Whitestone had $264.7 million of real estate debt with a consolidated debt to annualized first quarter 2014 earnings before interest, taxes, depreciation and amortization ("EBITDA") of 7.45x. Real estate debt as a percentage of total market capitalization was 45% as of March 31, 2014 and the Company's ratio of EBITDA to interest expense was 4.1x in the first quarter of 2014.

Whitestone had 41 properties unencumbered by mortgage debt as of March 31, 2014, with an undepreciated cost basis of $358.9 million. The total undepreciated value of the Company's real estate assets and real estate indebtedness was $548.2 million and $436.3 million as of March 31, 2014 and 2013, respectively. As of March 31, 2014, $179.8 million, or approximately 68%, of the Company's debt was subject to fixed interest rates. The Company's weighted average interest rate on all debt and on fixed-rate debt as of the end of the first quarter of 2014 was 3.3% and 3.8%, respectively.

At quarter end, Whitestone had $3.4 million of cash available on its balance sheet and $90.2 million of available capacity under its credit facility, including the accordion option.

Dividend

The Company declared a quarterly cash distribution of $0.285 per common share and OP unit for the second quarter of 2014, paid or to be paid in three equal installments of $0.095 in April, May and June 2014. The dividend amount per share has remained the same since the distribution paid on July 8, 2010.

Earnings Guidance

Whitestone is reiterating its 2014 guidance:

• FFO Core in the range of $1.09 to $1.18 per diluted share and OP unit;

• FFO in the range of $0.88 to $0.97 per diluted share and OP unit; and

• EPS in the range of $0.22 to $0.30 per diluted share. Guidance for EPS excludes gains on real estate transactions.

The midpoint of the Company’s 2014 earnings guidance assumes acquisitions of $60 million, dispositions of $15 million, and development of $15 million during 2014. The net impact to 2014 FFO Core from projected 2014 acquisitions, net of dispositions and interest cost is approximately $0.03 to $0.05 per diluted share. Whitestone expects same-property NOI growth between 4% and 7%.

Additional information on the Company’s 2014 financial outlook and a reconciliation of expected net income attributable to common shareholders to expected FFO and FFO Core are included in the financial tables accompanying this press release.

Forward-Looking Statements

Certain statements contained in this press release constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act") and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). 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" or similar words or phrases that are predictions of future events or trends and which do not relate solely to historical matters. Examples of such statements in this press release include, but are not limited to, the strength of the Company's leasing portfolio and lease renewal activities.

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 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; the Company's ability to successfully identify and consummate suitable acquisitions; 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 and regulatory changes; 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; 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.

Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this press release. The Company cannot guarantee the accuracy of any such forward-looking statements contained in this press release, and the Company does not intend to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.

Non-GAAP Financial Measures

This release contains the 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 the National Association of Real Estate Investment Trusts, ("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 and acquisition costs. 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.

EBITDA: Management believes that EBITDA is an appropriate supplemental measure of operating performance to net income attributable to the Company. The Company defines EBITDA as operating revenues (rental and other revenues) less property and related expenses (property operation and maintenance and real estate taxes) and general and administrative expenses. Management believes that EBITDA provides useful information to the investment community about the Company's operating performance when compared to other REITs since EBITDA is generally recognized as a standard measure. However, EBITDA should not be viewed as a measure of the Company's overall financial performance since it does not reflect depreciation and amortization, involuntary conversion, interest expense, 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 EBITDA and, accordingly, the Company's EBITDA may not be comparable to other REITs.
