Andrew Krakauer, Cantel Medical’s President and CEO, stated, “We are pleased to have delivered record sales and strong earnings performance again this quarter.  We achieved significant revenue growth in our three major business segments — Endoscopy, Water Purification and Filtration, and Healthcare Disposables. All three business units have greatly benefited from further investments in new product development, sales and marketing programs and the integration of recent acquisitions for this quarter and for the full year. Most importantly this quarter, we had strong organic sales growth of 13%, and have exceeded 10% organic growth for the past five consecutive quarters.”

Krakauer added, “Our Medivators Endoscopy business led sales growth for the company this quarter with a year-over-year increase of 23%, of which 20% was organic. This unit achieved record sales for the fourth consecutive quarter with double digit growth in all product categories. Further, we were pleased to have announced on July 1, that Cantel acquired PuriCore International Limited, which is now called Cantel Medical (UK) Limited. The addition of this United Kingdom-based company further enhances Cantel’s global leadership in the automated endoscope reprocessor and related chemistries business.

Our Mar Cor Water Purification and Filtration unit continued its excellent performance as it has all fiscal year with sales growth this quarter of 14%, of which 11% was organic. Sales growth in this segment was led by increased shipments of central and portable water purification equipment. In our Crosstex Healthcare Disposables segment, sales grew 6% for the quarter, all of which was organic.

We are optimistic about Cantel’s prospects to grow sales and increase profits in fiscal year 2015. We expect to benefit from our significant prior and ongoing investments in sales and marketing, continued progress with new products, as well as from recent and future acquisitions.”

The Company further reported that its balance sheet at July 31, 2014 included current assets of $163,909,000, including cash of $31,781,000, a current ratio of 2.5:1, gross debt of $80,500,000 and stockholders’ equity of $365,246,000. Krakauer stated, “The Company has a strong balance sheet and continues to generate significant cash flow and EBITDAS. For the full fiscal year 2014, EBITDAS grew by 13.5% to $95,724,000. Despite borrowing $28 million to fund the acquisition of PuriCore in June, our net debt position since the third quarter increased only about $9 million to $48,719,000.”

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 twelve months ended July 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.
