U-Store-It Trust Reports Operating Results for the Three Months Ended March 31, 2008

15% Increase in FFO per Share


CLEVELAND, OH--(Marketwire - May 8, 2008) - U-Store-It Trust (NYSE: YSI) announced its operating results for the three months ended March 31, 2008. "We are pleased to report very strong first quarter earnings. Our self-storage facilities are looking their best and our people and our systems are fully prepared heading into our prime rental season," said Dean Jernigan, President and Chief Executive Officer of U-Store-It.

Significant highlights of the quarter include:

--  Funds from Operations ("FFO") of $0.24 per share for the three months
    ended March 31, 2008, a 14.6% increase over the $0.21 per share reported in
    the same period of the previous year.
--  An increase in first quarter rental income and total revenue on the
    386 same-store facilities by 6.6% and 5.0%, respectively, when compared to
    the three months ended March 31, 2007.
--  An increase in first quarter net operating income ("NOI") on the 386
    same-store facilities by 4.3% when compared to the three months ended March
    31, 2007.
--  Average first quarter same-store physical occupancy (calculated on
    square feet) of 79.4%, a gain of 100 basis points over the first quarter of
    2007.
--  A 3.2% increase, or 1,100 additional units rented across the portfolio
    in the first quarter of 2008 compared to the same quarter of last year.
    

President and Chief Executive Officer Dean Jernigan commented, "We are very encouraged by our first quarter same-store revenue growth hitting the top-end of our expectations and our same-store net operating income growth and average physical occupancy exceeding our expectations. A second straight quarter of solid internal growth and growth in FFO per share, as well as a strong April, with net rentals up 29% from April of 2007, provides us with an excellent platform to continue to build upon throughout the balance of the year."

Funds from Operations

FFO for the first quarter of 2008 was $14.8 million, compared to $12.9 million for the first quarter of 2007. FFO per share grew 14.6% to $0.24 per share for the first quarter of 2008, compared to $0.21 for the same quarter of last year. The Company's first quarter of 2008 FFO was negatively impacted by approximately $0.01 per share attributable to the Company's development asset acquired in January 2007 and the lease-up portfolio acquired in September 2007.

Operating Results

The Company reported a net loss of $4.0 million or $0.07 per share in the first quarter of 2008, compared to a net loss of $3.4 million or $0.06 per share for the quarter ended March 31, 2007.

Total revenues increased $5.4 million and property operating expenses increased $2.5 million in the first quarter of 2008, compared to the same period in 2007. Increases in total revenues and property operating expenses are attributable to the acquisition of 15 self-storage facilities for approximately $134.5 million since March 31, 2007 and increases in same-store revenues and expenses. Depreciation expense increased $3.4 million in the first quarter of 2008 compared to the same quarter of 2007 due to additional depreciation and amortization of intangible assets attributable to the acquisition of self-storage facilities. General and administrative expenses decreased by $0.5 million in the first quarter of 2008 compared to the same period in 2007.

Interest expense increased approximately $1.0 million in the first quarter of 2008, compared to the first quarter of 2007, primarily as a result of the additional debt used to fund the acquisition of 15 facilities purchased since March 31, 2007.

The Company's 408 owned facilities, containing 26.1 million rentable square feet, had a physical occupancy at March 31, 2008 of 78.8% (79.1% exclusive of the lease-up assets) and an average physical occupancy for the quarter ended March 31, 2008 of 78.9% (79.3% exclusive of the lease-up assets).

Same-Store Results

The Company's same-store pool at March 31, 2008 represented 386 facilities containing approximately 24.5 million rentable square feet and representing approximately 93.7% of the aggregate rentable square feet of the Company's 408 owned facilities. These same-store facilities represent approximately 94.6% of property net operating income for the quarter ended March 31, 2008.

The same-store average physical occupancy for the first quarter of 2008 was 79.4% compared to 78.4% for the same quarter of last year. In-place annual rent per square foot grew 1.9% to $12.16 in the first quarter of 2008 over the same quarter of last year. Same-store rental income for the first quarter of 2008 grew 6.6% over the same period in 2007. Same-store total revenues and operating expenses grew 5.0% and 6.2%, respectively, over the first quarter of 2007. Same-store net operating income grew 4.3% in the first quarter of 2008 compared to the same quarter of 2007.

Acquisition and Disposition Activity

During January 2008, we acquired a self-storage facility in Washington D.C. of approximately 63,000 square feet for $13.3 million. This is one of our identified core growth markets and we plan to recycle a portion of our capital into these markets going forward.

During March 2008, we disposed of two facilities in Florida for aggregate proceeds of $4.6 million and recognized gains totaling $0.6 million. We do not include these gains in our $0.24 of FFO per share.

Quarterly Dividend

On February 27, 2008, the Company declared a dividend of $0.18 per share. The dividend was paid on April 22, 2008, to shareholders of record on April 7, 2008.

Second Quarter and Full Year 2008 Financial Outlook

"As a result of our strong first quarter performance, we are raising our full year guidance for FFO per share by 6% at the low-end and by 4% at the mid-point of our range. Our revised guidance for 2008 represents growth of 8% to 13% over our 2007 FFO per share," said Christopher Marr, Chief Financial Officer. "We intend to accelerate our efforts to improve our balance sheet and create additional liquidity through both our asset disposition program, as well as exploring raising institutional capital, primarily through the joint venture format," Mr. Marr went on to say.

The Company is revising its previously issued 2008 earnings guidance and estimates that its fully-diluted FFO per share will be between $0.93 and $0.97, and that its fully-diluted net loss per share for the period will be between $0.23 and $0.27. The Company's estimate is based on the following key assumptions:

--  General and administrative expenses of approximately $22.5-$23.5
    million
--  Same-store average occupancy of 82.0%-84.0%
--  Same-store revenue growth of 4.5%-5.0%
--  Same-store expense growth of 3.5%-4.0%
--  Same-store net operating income growth of 4.5%-5.5%
--  Dilution during 2008 from the 15 development/lease-up properties of
    approximately $0.02 to $0.03 per share

About U-Store-It Trust

U-Store-It Trust is a self-administered and self-managed real estate investment trust. The Company's self-storage facilities are designed to offer affordable, easily accessible and secure storage space for residential and commercial customers. According to the Self-Storage Almanac, U-Store-It Trust is one of the top four owners and operators of self-storage facilities in the United States.

Non-GAAP Performance Measurements

FFO is a widely used performance measure for real estate companies and is provided here as a supplemental measure of operating performance. The Company calculates FFO in accordance with the best practices described in the April 2002 National Policy Bulletin of the National Association of Real Estate Investment Trusts (the "White Paper"). The White Paper defines FFO as net income (computed in accordance with GAAP), excluding gains (or losses) from sales of property, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.

Management uses FFO as a key performance indicator in evaluating the operations of the Company's facilities. Given the nature of its business as a real estate owner and operator, the Company considers FFO a key measure of its operating performance that is not specifically defined by accounting principles generally accepted in the United States. The Company believes that FFO is useful to management and investors as a starting point in measuring its operational performance because it excludes various items included in net income that do not relate to or are not indicative of its operating performance such as gains (or losses) from sales of property and depreciation, which can make periodic and peer analyses of operating performance more difficult. FFO should not be considered as an alternative to net income (determined in accordance with GAAP) as an indicator of the Company's financial performance, is not an alternative to cash flow from operating activities (determined in accordance with GAAP) as a measure of the Company's liquidity, and is not indicative of funds available to fund the Company's cash needs, including its ability to make distributions.

We define net operating income, which we refer to as "NOI," as total continuing revenues less continuing property operating expenses. NOI also can be calculated by adding back to net income: interest expense, loan procurement amortization expense, early extinguishment of debt, minority interest, loss on sale of storage facilities, depreciation and general and administrative, and deducting from net income: income from discontinued operations, gains on sale of self-storage facilities, and interest income. NOI is not a measure of performance calculated in accordance with GAAP.

Management uses NOI as a measure of operating performance at each of our facilities, and for all of our facilities in the aggregate. NOI should not be considered as a substitute for operating income, net income, cash flows provided by operating, investing and financing activities, or other income statement or cash flow statement data prepared in accordance with GAAP.
