All amounts in this news release are in United States dollars.

Third Quarter 2012 Highlights

“We have now filed our outstanding quarterly reports for 2012,” said Thomas Byrne, President and Chief Executive Officer of Swisher Hygiene. “We are working to file our 2012 Form 10-K as soon as possible, and once again thank our shareholders for their patience and continued support during this process.”

Third Quarter 2012 Results

For the three months ended September 30, 2012, Swisher Hygiene reported total revenue from continuing operations of $59.0 million, a 20% increase from $49.2 million in the three months ended September 30, 2011. Hygiene revenue from company-owned operations, excluding acquisitions, increased 3% compared to the three months ended September 30, 2011.

Total costs and expenses for the three months ended September 30, 2012 increased by 41% to $72.8 million, compared to $51.7 million in the three months ended September 30, 2011.

For the three months ended September 30, 2012 and 2011, respectively:

The increase in cost of sales as a percentage of revenue primarily reflects a change in sales mix towards the chemical product line and entering the wholesale chemical business through Swisher Hygiene’s acquisition of Daley International, Cavalier and Kitter spanning the third quarter of 2011, while the favorable change in route expense as a percentage of revenue reflects economies of scale realized through route consolidation initiatives.

Non-GAAP Financial Measures

This press release and the attached financial tables contain certain non-GAAP financial measures. In addition to net income determined in accordance with GAAP, we use certain non-GAAP measures such as “Adjusted EBITDA” in assessing Swisher Hygiene’s operating performance. Swisher Hygiene believes this non-GAAP measure serves as an appropriate measure to be used in evaluating the performance of its business.

Swisher Hygiene defines Adjusted EBITDA as net loss excluding the impact of income taxes, depreciation and amortization expense, investigation and review related expenses, net interest expense, foreign currency gain or loss and other income, net gain on debt related fair value measurements, stock based compensation, third party costs directly related to merger and acquisitions including the debt prepayment penalty, and a gain from bargain purchase related to mergers and acquisitions.

Swisher Hygiene presents Adjusted EBITDA because the company considers it an important supplemental measure of its operating performance and believes it is frequently used by securities analysts, investors and other interested parties in the evaluation of its results. Management uses this non-GAAP financial measure frequently in its decision-making because it provides supplemental information that facilitates internal comparisons to the historical operating performance of prior periods and gives an additional indication of Swisher Hygiene’s core operating performance. Swisher Hygiene includes this non-GAAP financial measure in its earnings announcement in order to provide transparency to its investors and enable investors to better compare its operating performance with the operating performance of its competitors. Adjusted EBITDA should not be considered in isolation from, and is not intended to represent an alternative measure of, revenue, operating results or cash flows from operating activities as determined in accordance with GAAP. Additionally, Swisher Hygiene’s definition of Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies.

Under SEC rules, Swisher Hygiene is required to provide a reconciliation of non-GAAP measures to the most directly comparable GAAP measures. Accordingly, the following is a reconciliation of Adjusted EBITDA to Swisher Hygiene’s net losses for the three and nine months ended September 30, 2012 and 2011:
