Deregistration of Securities

This Post-Effective Amendment relates to the following Registration Statements on Form S-8 (collectively, the “Registration Statements”) of Cantel Medical LLC (f/k/a Cantel Medical Corp.) (the “Registrant”), which have been previously filed with the Securities and Exchange Commission (the “Commission”), to deregister any and all shares of the Registrant’s common stock, par value $0.10 per share (“Common Stock”), registered but unsold or otherwise unissued under each such Registration Statement as of the date hereof (note that the share numbers listed below do not take into account corporate actions, such as stock splits, that may have been taken in the interim):

On June 2, 2021, pursuant to the terms of the Agreement and Plan of Merger, dated as of January 12, 2021, as amended, by and among the Registrant, STERIS plc, a company incorporated under the laws of Ireland (“Parent”), Solar New US Holding Corporation (f/k/a Solar New US Holding Co, LLC), a Delaware corporation and indirect and wholly-owned subsidiary of Parent (“US Holdco”), and Crystal Merger Sub 1, LLC, a Delaware limited liability company and direct and wholly-owned subsidiary of US Holdco, Parent completed its previously announced acquisition of the Registrant in a series of transactions (the “Mergers”).

As a result of the Mergers, any offerings of the Registrant’s securities pursuant to the Registration Statements have been terminated. This Post-Effective Amendment to the Registration Statements is being filed to terminate the effectiveness of the Registration Statements and remove from registration any and all securities previously registered but unsold under the Registration Statements as of the effective time of the Mergers. In accordance with undertakings made by the registrant in the Registration Statements to remove from registration, by means of a post-effective amendment, any of the securities registered under the Registration Statements that remain unsold at the termination of the offering, the registrant hereby removes from registration the securities registered but unsold under the Registration Statements, if any.
