CANTEL MEDICAL REPORTS 25% INCREASE IN NET INCOME - EPS OF $0.35 vs. $0.29 - FOR QUARTER ENDED OCTOBER 31, 2011 ON 30% SALES INCREASE

LITTLE FALLS, New Jersey (December 8, 2011) ... CANTEL MEDICAL CORP. (NYSE:CMN) reported a 25% increase in net income to $6,220,000, or $0.35 per diluted share, on a 30% increase in sales to a record $93,262,000 for the first quarter ended October 31, 2011. This compares with net income of $4,975,000, or $0.29 per diluted share, on sales of $71,993,000 for the first quarter ended October 31, 2010.

Andrew Krakauer, Cantel’s President and CEO stated, “We are pleased to have delivered record sales and strong quarterly earnings. These positive results confirm the continued success of our three prong approach to growth which includes investing in new product development, sales and marketing programs and acquisitions. All of these strategies positively affected the results this quarter.”

Krakauer added, “Our Endoscopy segment had an especially stellar performance this quarter as organic sales grew by 25%, excluding sales from our newly acquired Byrne Medical business. This growth was driven by increased shipments of our newest reprocessor, the DSD Edge™, as well as disinfectants and sterilants, parts and service. Byrne Medical, which is in the process of being integrated into the Endoscopy segment, had core sales growth in excess of 30% and was accretive to earnings in the quarter. We also had excellent performance in our Water Purification and Filtration segment, where sales growth of 21% and effective integration of the Gambro water acquisition resulted in a 57% increase in operating income.”

The Company also reported that its balance sheet at October 31, 2011 included current assets of $118,617,000, including cash of $19,646,000, a current ratio of 2.27:1, gross debt of $116,500,000 and stockholders’ equity of $247,257,000. Krakauer stated, “We continue to maintain a strong balance sheet and generate substantial cash flow and EBITDAS. When compared with the same quarter last year, our EBITDAS grew by 36% to $15,680,000. We were able to reduce our net debt position by approximately $7 million to $96,854,000, since the close of the Byrne Medical acquisition on the first day of this quarter.”

SUPPLEMENTARY INFORMATION

Reconciliation of Earnings Before Interest, Taxes, Depreciation, Amortization and Stock-Based Compensation Expense (“EBITDAS”)

The reconciliation of EBITDAS with net income for the three months ended October 31, 2011 and 2010, respectively, is as follows (in thousands):

	Three Months Ended
	October 31,
	2011			2010

Net income	$	6,220		$	4,975

Income taxes	3,559			2,617
Interest expense	1,031			241
Interest income	(30		)	(19		)
Depreciation	1,677			1,628

EBITDA	14,749			10,750

EBITDAS	$	15,680		$	11,515

EBITDAS is a measure of the Company’s performance that is not required by, or presented in accordance with, Generally Accepted Accounting Principles (“GAAP”). EBITDAS is a non-GAAP financial measure defined by the Company as income before interest, taxes, depreciation, amortization and stock-based compensation expense. The Company believes EBITDAS is an important valuation measurement for management and investors given the increasing effect that non-cash charges, such as stock-based compensation, amortization related to acquisitions and depreciation of capital equipment, has on the Company’s net income. In particular, acquisitions have historically resulted in significant increases in amortization of intangible assets that reduced the Company’s net income. Additionally, the Company regards EBITDAS as a useful measure of operating performance and cash flow before the effect of interest expense and complements operating income, net income and other GAAP financial performance measures. Generally, a non-GAAP financial measure is a numerical measure of a Company’s performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. This measure, however, should be considered in addition to, and not as a substitute or superior to, net income, cash flows, or other measures of financial performance prepared in accordance with GAAP.
