Cantel Announces Amended Credit Facility; Provides Update on COVID Impact

Little Falls, New Jersey – (May 12, 2020) - CANTEL MEDICAL CORP. (NYSE:CMD) announced today several business and financial updates in light of the ongoing COVID pandemic.

Operating Update in Response to COVID

Given the COVID-related government lockdowns and social distancing initiatives, the Company has seen a deferral of elective medical and dental procedures across markets in which Cantel operates. The Company reacted early to these headwinds to ensure that it could protect its employees, deliver resilience across its supply chain and best position itself for the recovery period during which such deferred procedures will resume. Ultimately, the Company believes that the core value proposition of its ‘complete circle of protection’ offering of infection prevention solutions are even more critical and relevant as we serve customer needs in the post-COVID recovery.

Operationally, the Company has taken significant measures to ensure that its supply chain remains fully operational through the crisis, with all facilities open and manufacturing, while adhering to local regulations. The Company has taken the following actions to preserve cash flow through this period:

Commenting on the current situation, George Fotiades, President and CEO stated, “The COVID pandemic has been an historic event for the industry, our customers, the patients who benefit from our products and services and our Company. I am proud of how our company has operated through these challenges and believe we are well positioned for the recovery in elective procedure volumes. The announcements today put us in a very strong position to navigate the crisis with ample flexibility. A key priority continues to be supporting those on the front lines of this pandemic by supplying much needed PPE, disinfectant chemistries and other infection prevention solutions to those who need it most. We also continue to make important progress on the growth initiatives of Cantel 2.0 which we presented at our last earnings call.”

Amendment of Credit Facilities to Increase Financial Flexibility

On May 11, 2020, the Company entered into an agreement to amend its credit facilities with its lender group. These changes will provide Cantel with ample flexibility to manage through the expected impacts of this difficult operating environment, and enable the Company to be well positioned to serve the needs of its customers in a post-COVID environment.

The principal changes to the credit facilities include:

As of April 30, 2020, the Company had a cash and cash equivalents balance of approximately $110 million and a revolving credit facility outstanding balance of approximately $400 million.

Revenue Update for the Fiscal Third Quarter and Withdrawn Guidance for the Remainder of the Year

As stated previously, the government lockdowns and social distancing initiatives related to the COVID pandemic have led to disruption across many of the markets in which Cantel operates. This disruption had the most pronounced impact over the last five weeks of Cantel’s third quarter, which ended April 30, 2020.

Revenue for the third quarter is estimated at $235–$237 million, down approximately 18% sequentially vs. the prior quarter. Over the last five weeks of the third quarter, the segments of the business most exposed to electives procedures were down approximately 65% versus the second quarter of fiscal year 2020. The Company expects this recent weakness to continue into its fourth quarter, and gradually improve as elective procedures are restored in its end markets. The Company expects to provide a complete update of its financial results for the third quarter on June 4, 2020.

Given the significant uncertainty related to the COVID pandemic, the Company is also withdrawing its financial guidance for fiscal year 2020.

Our estimated unaudited financial results as of and for the three months ended April 30, 2020 presented above are preliminary and are subject to the close of the quarter, completion of our quarter-end closing procedures and further financial review.
