Mac-Gray Corporation Announces First-Quarter 2010 Financial Results

Company Delivers Solid Performance, Despite Difficult Multi-Housing Environment;

Generates Strong Cash Flow and Reduces Funded Debt by $17.3 Million

WALTHAM, MA, May 6, 2010 – Mac-Gray Corporation (NYSE: TUC), the nation’s premier provider of laundry facilities management services to multi-unit housing locations, today announced its financial results for the quarter ended March 31, 2010.

Mac-Gray reported first-quarter revenue from continuing operations of $81.5 million, compared with $85.3 million in the first quarter of 2009. Net income from continuing operations for the first quarter of 2010 was $1.5 million, or $0.11 per diluted share, compared with net income from continuing operations of $1.9 million, or $0.14 per diluted share, for the first quarter of 2009. First-quarter 2010 net income from continuing operations includes a loss of $242,000 related to derivative instruments and $97,000 in incremental proxy-related costs. First-quarter 2009 net income from continuing operations included a gain on the sale of real estate of $403,000 and an unrealized gain of $62,000 related to derivative instruments and incremental proxy-related costs of $378,000. Excluding these items from both periods, adjusted net income from continuing operations for the first quarter of 2010 was $1.7 million, or $0.12 per diluted share, compared with adjusted net income from continuing operations of $1.8 million, or $0.13 per diluted share, for the same period of 2009.

Please refer to Table 1, included at the end of this news release, for a reconciliation of net income from continuing operations, as reported, to net income from continuing operations, as adjusted.

For the first quarter of 2010, Mac-Gray’s earnings before interest expense, provision for income taxes, depreciation and amortization expense (EBITDA) from continuing operations was $18.3 million, compared with $21.0 million in the year-earlier quarter. EBITDA from continuing operations, excluding all gains and losses relating to derivative instruments, sale of real estate gains and incremental proxy-related costs, was $18.6 million for the first quarter of 2010, compared with $20.9 million in the year-earlier quarter.

Please refer to Table 2, included at the end of this news release, for a reconciliation of net income from continuing operations to EBITDA from continuing operations and EBITDA from continuing operations, as adjusted.

Results of Discontinued Operations

Income from discontinued operations in the first quarter of 2010 was $44,000 compared with income from discontinued operations of $357,000 in the comparable period of 2009, reflecting the sale of the business in early February.

Comments on the First Quarter

“We delivered solid results in the first quarter despite a very difficult multi-housing environment,” said Stewart G. MacDonald, Mac-Gray’s chief executive officer. “The ongoing record apartment vacancy rates are continuing to affect our core laundry facilities management business in several ways, and consequently first-quarter revenue in our core business declined by 3% year-over-year.”

“Our commercial laundry equipment sales business, which represents approximately 4% of total revenues, was down 26% in the first quarter as challenging trends continue to affect that business. Our customers, who are mostly small business owners, are hesitant to invest based on the economy and are extending the life of outdated equipment. We expect commercial laundry equipment sales to experience continued weakness in the near-term until those conditions improve.”

“While our top-line remained under pressure in the quarter, we continued to carefully manage our capital resources and control our costs wherever possible. Because of our prudent capital allocation, and also as a result of timing, capital expenditures, including incentive payments and capital leases, in the first quarter were $3.2 million compared with $8.2 million for the same period in 2009 and $4.7 million in the fourth quarter. SG&A expenses were also down year over year as a result of an organization-wide effort to control and reduce expenses. At the same time, interest expense was down 22% due to the steady pay down of our funded debt as well as the effect of the Company’s new interest rate structure.”

“By selectively allocating capital and controlling costs, we continued to maximize our cash flow during the quarter. Despite the lower revenue, we reduced our funded debt balance by $17.3 million in the first quarter, which includes the use of $8.5 million in proceeds received from our previously announced sale of MicroFridge. In the trailing 12 months, we have reduced our funded debt by more than $44 million. With this strong reduction of debt, combined with our predictable and stable cash flow, the Company was also able to initiate a dividend program on April 1st.”

Outlook

“While the data is not yet conclusive, it appears that apartment vacancy rates may have begun to peak. A recently issued industry report showed that the nationwide apartment vacancy rate was unchanged in the first quarter versus year-end, and several leading industry metrics, such as a rise in apartment rents, were positive. For Mac-Gray, our same location revenue was down 2% in the first quarter, which is a slower rate of decline than in the past several quarters. Overall, we

continue to see early signs of stabilization in a number of markets and even certain pockets of improvement across the country. These are encouraging signs for a return to more normalized levels, but we also continue to expect our industry’s rebound to lag a broader economic recovery.”

“We remain cautious about capital allocation during this challenging economic period. Our philosophy has been that it is more sensible to apply our free cash to debt reduction in this environment than put our capital to work earning less than desirable returns. However, our capital spending will increase during the remainder of the year from the abnormally low first-quarter level. Our goal remains to maintain the relative size of our overall contract portfolio by investing in the most attractive markets.”

“During the past two years, our core business has proven its resiliency and we have taken steps to counteract the effects of the recession. Despite the effects of the recession and the fact that we are a capital-intensive business, we have still reduced our funded debt by $83 million since our last acquisition in April 2008, and have dramatically improved our leverage ratios during that time. With an eventual economic recovery on the horizon, we remain confident in our long-term outlook and we believe that we will emerge from this as a far stronger and well-positioned Company,” MacDonald concluded.

The Company will host a conference call at 10:00 a.m. ET today during which Stewart MacDonald, Mac-Gray’s chief executive officer, and Michael Shea, executive vice president and chief financial officer, will summarize the Company’s financial results, review business and operating highlights from the quarter, and provide a business and financial outlook.

To supplement the Company’s unaudited condensed consolidated financial statements presented on a generally accepted accounting principles (GAAP) basis, management has used a non-GAAP measure of net income. Management believes that the presentation of “Income from continuing operations as adjusted” is useful to investors to enhance an overall understanding of our historical financial performance and future prospects. Adjusted net income from continuing operations, which is adjusted to exclude certain gains and losses from the comparable GAAP net income is an indication of our baseline performance before gains, losses or other charges that are considered by management to be outside of our core operating results. These non-GAAP results are among the primary indicators management uses as a basis for evaluating the Company’s financial performance as well as for forecasting future periods. Management establishes performance targets, annual budgets and makes critical operating decisions based upon these metrics. Accordingly, disclosure of these non-GAAP measures provides investors with the same information that management uses to understand the Company’s true economic performance year over year. The presentation of this additional information is not meant to be considered in isolation or as a substitute for net income or other measures prepared in accordance with GAAP.

(2) Represents the un-realized (gain) loss on interest rate protection contracts, which do not qualify for hedge accounting treatment.

EBITDA from continuing operations is defined as net income before interest expense, provision for income taxes, and depreciation and amortization expense. Adjusted EBITDA from continuing operations is EBITDA from continuing operations further adjusted to exclude the items described in the table above. We have excluded these items because we believe they are not reflective of our ongoing operating performance. EBITDA from continuing operations and Adjusted EBITDA from continuing operations are not measures of our liquidity or financial performance under GAAP and should not be considered as alternatives to net income or any other performance measure derived in accordance with GAAP, or as an alternative to cash flows from operating activities as a measure of our liquidity.

Our management believes EBITDA from continuing operations and Adjusted EBITDA from continuing operations are useful to investors because they help enable investors to evaluate our business in the same manner as our management. Management uses EBITDA from continuing operations and Adjusted EBITDA from continuing operations as follows: (a) to evaluate the Company’s historical and prospective financial performance, (b) to set internal revenue targets and spending budgets, (c) to measure operational profitability and the accuracy of forecasting, and (d) as an important factor in determining variable compensation for management. In addition, these measures are frequently used by securities analysts, investors and other interested parties in the evaluation of companies with substantial financial leverage. Moreover, investors have historically requested and the Company has historically reported these non-GAAP financial measures as a means of providing consistent and comparable information with past reports of financial results.

While management believes that these non-GAAP financial measures provide useful supplemental information to investors, there are limitations associated with the use of these non-GAAP financial measures. These measures are not prepared in accordance with GAAP and may not be directly comparable to similarly titled measures of other companies due to potential differences in the exact method of calculation. Further, EBITDA from continuing operations and Adjusted EBITDA from continuing operations exclude interest expense and depreciation and amortization expense, which represent significant and unavoidable operating costs given the level of indebtedness and the capital expenditures needed to maintain our business. In addition, our measures of EBITDA from continuing operations and Adjusted EBITDA from continuing

operations are different from those used in the covenants contained in our senior credit facilities and the indenture governing our 7 5/8% senior notes. Management compensates for these limitations by relying primarily on our GAAP results and by using EBITDA from continuing operations and Adjusted EBITDA from continuing operations only supplementally and by reviewing the reconciliations of the non-GAAP financial measures to their most comparable GAAP financial measures.

Non-GAAP financial measures are not in accordance with, or an alternative for, generally accepted accounting principles in the United States. The Company’s non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures, and should be read only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP.
