Andrew Krakauer, Cantel’s President and CEO stated, “We are pleased to have delivered record sales and solid earnings performance in the second quarter. These positive results confirm the continued success of our strategic approach to growth which includes investing in new product development, sales and marketing programs and acquisitions. Most importantly, for the third consecutive quarter we had strong organic sales growth of 10%.”

Krakauer added, “Financial performance was led this quarter by our Water Purification and Filtration unit where year-over-year sales increased 26%, of which 18% was organic. The record sales in this segment were led by increased shipments of central and portable water purification equipment. Our Medivators Endoscopy business also had excellent

organic growth of 13% for the quarter and achieved record sales for the second consecutive quarter. In this segment, organic growth was driven by strength in disinfectant chemicals, procedural products, as well as service and spare parts. Also during the quarter, the Company completed two small but strategically important acquisitions, including Jet Prep Ltd. in the Endoscopy segment and Sterilator Company, Inc. in the Healthcare Disposables segment.

Our strong revenue increases have allowed us to improve earnings, even as we are increasing investments in sales and marketing and new product development. Further, we are taking an aggressive approach in building our international sales, marketing, and operations teams to grow this part of our business in the medium-term. Overall, we expect to continue to accelerate these investments over the next several quarters, while remaining committed to an active global acquisition program.

The Company further reported that its balance sheet at January 31, 2014 included current assets of $147,963,000, including cash of $19,706,000, a current ratio of 3.1:1, gross debt of $74,500,000 and stockholders’ equity of $342,018,000.  Krakauer stated, “The Company has a strong balance sheet and continues to generate significant cash flow and EBITDAS.  When compared with the same quarter last year, our EBITDAS grew by 10% to $24,437,000. EBITDAS for the first six months of fiscal year 2014 of $48,585.000 is 12% ahead of the same period in the prior year.” Subsequent to quarter-end on March 4, 2014, the Company significantly increased its overall financial flexibility and access to capital by entering into a $250,000,000 amended and restated credit facility with its existing bank syndicate which established new and improved terms under its revolving credit facility including an expansion of borrowing capacity, a decrease in applicable rates used for borrowings, the ability to borrow in multiple currencies and an extension of the expiration date to March 4, 2019.

SUPPLEMENTARY INFORMATION

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

(unaudited)

The reconciliation of EBITDAS with net income for the three and six months ended January 31, 2014 and 2013, respectively, is as follows (in thousands):

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.
