SWISHER HYGIENE ANNOUNCES RESULTS FOR THE THREE MONTHS AND YEAR

ENDED DECEMBER 31, 2012

CHARLOTTE, NC – May 1, 2013 – Swisher Hygiene Inc. (“Swisher Hygiene”) (NASDAQ: SWSH, TSX: SWI), a leading provider of essential hygiene and sanitizing products and services, announced today fourth quarter and full year results, as well as the filing of its Form 10-K, for the period ended December 31, 2012. All amounts in this news release are in United States dollars.

Fourth Quarter 2012 Highlights

• The Waste segment, which was sold on November 15, 2012, is reported as discontinued operations for 2012.

• Total revenue from continuing operations of $53.2 million for the fourth quarter of 2012, a 4% decrease compared to the fourth quarter of 2011. Hygiene revenue from company-owned operations for the fourth quarter of 2012, excluding acquisitions, decreased 7% compared to the fourth quarter of 2011.

• Adjusted EBITDA loss of $5.3 million for the fourth quarter of 2012, based on a net loss from continuing operations before income taxes of $16.6 million, and compared to an Adjusted EBITDA loss of $6.5 million for the fourth quarter of 2011. For a reconciliation of non-GAAP to GAAP measures, please review the disclosures and table included with this release.

• Basic and diluted loss per share from continuing operations of $0.20 for the fourth quarter of 2012, compared to basic and diluted loss per share from continuing operations of $0.05 in the fourth quarter of 2011.

“With today’s release and the filing of our 10-K, we will have completed the restatement process and our 2012 public reporting obligations,” said Thomas Byrne, President and Chief Executive Officer of Swisher Hygiene. “We again thank our shareholders for their patience and continued support over the past year.”

“Our fourth quarter 2012 results were affected by the investigation and review process that was completed in February 2013, which impacted our top line growth and bottom line results,” continued Mr. Byrne. “As a result of the overall process, we lost a couple of large accounts, from which we will continue to see effects in the first half of 2013. However, we are encouraged by the renewed interest we have seen in our corporate account and distributor programs during the first quarter of 2013, and we will continue to expand our field cross-selling programs while emphasizing customer service, retention and new customer acquisition. Additionally, we continue to simplify and standardize operations, which is enhancing our customer service and allowing us to further eliminate costs and improve cash flow.”

“Also during the fourth quarter, we sold our water treatment operation we had previously acquired as part of our acquisition of Mount Hood Solutions, to U.S. Water Services (USWS). As part of the sale, we are now working with USWS to jointly market our complementary services. Similar to our sale of Choice, while we were very pleased with the performance of this entity, we believe a less capital intensive approach to providing these services makes more sense for our customers, who will still be able to enjoy the benefits of this service on a national scale,” concluded Mr. Byrne.

Fourth Quarter 2012 Results

For the three months ended December 31, 2012, Swisher Hygiene reported total revenue from continuing operations of $53.2 million, a 4% decrease from $55.7 million in the three months ended December 31, 2011. Hygiene revenue from company-owned operations, excluding acquisitions, decreased 7% compared to the three months ended December 31, 2011.

Total costs and expenses for the three months ended December 31, 2012 decreased 3% to $67.9 million, compared to $69.8 million in the three months ended December 31, 2011. Excluding the impact of acquisition and merger expenses, and $2.5 million of investigation and review-related expenses in the three months ended December 31, 2012, total costs and expenses increased 1% compared to the three months ended December 31, 2011.

For the three months ended December 31, 2012 and 2011, respectively:

	Q4 2012			Q4 2011
Cost of sales as a % of revenue		44.7	%		45.3	%
Route expense as a % of revenue		20.3	%		20.1	%
SG&A expense as a % of revenue		52.4	%		49.8	%
SG&A expense (excluding investigation and review-related expenses) as a % of revenue		47.6	%		49.8	%

The decrease in cost of sales as a percentage of revenue primarily reflects the positive effects of Swisher Hygiene’s manufacturing and supply chain initiatives, partially offset by a change in sales mix towards the chemical product line. Route expense as a percentage of revenue was essentially comparable from the prior-year period. SG&A as a percentage of revenue (excluding investigation and review-related expenses) declined primarily due to cost savings initiatives and was partially offset by a one-time accrual fee of $0.5 million attributable to the sale of Waste in the fourth quarter of 2012.

Net loss from continuing operations before income taxes for the three months ended December 31, 2012 was $16.6 million, compared to net loss from continuing operations before income taxes of $14.7 million in the three months ended December 31, 2011.

Adjusted EBITDA loss for the three months ended December 31, 2012 was $5.3 million, compared to an Adjusted EBITDA loss of $6.5 million in the three months ended December 31, 2011.

Full Year 2012 Results

For the full year ended December 31, 2012, Swisher Hygiene reported total revenue from continuing operations of $230.5 million, a 44% increase from $160.6 million in the full year 2011. Hygiene revenue from company-owned operations for the full year 2012, excluding acquisitions, increased 11% compared to the prior year.

Total costs and expenses for the full year ended December 31, 2012 increased by 48% to $289.5 million, compared to $195.2 million in the full year 2011. Excluding the impact of acquisition and merger expenses, and $18.9 million of investigation and review-related expenses for the full year ended December 31, 2012, and the gain from bargain purchase in 2011, total costs and expenses increased 34% compared to the full year 2011.

For the full years ended December 31, 2012 and 2011, respectively:

	FY2012			FY2011
Cost of sales as a % of revenue		44.2	%		42.3	%
Route expense as a % of revenue		18.4	%		20.7	%
SG&A expense as a % of revenue		53.5	%		49.5	%
SG&A expense (excluding investigation and review-related expenses) as a % of revenue		45.3	%		49.5	%

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 acquisitions of Daley International, Cavalier and Kitter, while the favorable change in route expense as a percentage of revenue reflects economies of scale realized through route consolidation initiatives. SG&A as a percentage of revenue (excluding investigation and review-related expenses) declined primarily due to cost savings initiatives.

Net loss from continuing operations before income taxes for the full year ended December 31, 2012 was $62.0 million, compared to net loss from continuing operations before income taxes of $41.3 million for the full year 2011.

Adjusted EBITDA loss for the full year ended December 31, 2012 was $12.6 million, compared to an Adjusted EBITDA loss of $14.8 million for the full year 2011.

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 change on debt related fair value measurements, stock based compensation, severance, 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 months and full year ended December 31, 2012 and 2011:
