All statements in the Presentation that do not directly and exclusively relate to historical facts constitute “forward looking statements.” Any such statements and projections reflect various estimates and assumptions by Direct Vet Marketing, Inc. (d/b/a Vets First Choice “we,” “us,” the “Company,” “Vets First Choice” or “VFC”) concerning anticipated results. Such statements are subject to numerous assumptions, risks, uncertainties and other factors that could cause actual results to differ materially from those described in such statements, including risks relating to the completion of the transaction, anticipating timing of the transaction, anticipated tax treatment, unforeseen liabilities, future capital expenditures, inability to achieve expected synergies, loss of revenues, delay or business disruption caused by difficulties integrating our business and the animal health businesses of Henry Schein, Inc. (“Henry Schein”) which we refer to as the “Henry Schein Animal Health Business” or “HSAH” as well as the matters described in the “Cautionary Note Regarding Forward-Looking Statements,” “Risk Factors,” and elsewhere in HS Spinco, Inc.’s (“Spinco” or “Covetrus”) filings with the U.S. Securities and Exchange Commission (“SEC”) including in the Registration Statement on Form S-4/S-1 (a copy of which can be found on SEC.gov). No representations or warranties are made by the Company, Henry Schein, Spinco or their respective affiliates as to the accuracy of any such statements or projections. Whether or not any such forward looking statements or projections are in fact achieved will depend upon future events some of which are not within the control of the Company. Accordingly, actual results may vary from the projected results and such variations may be material. These statements and projections speak only as of the date hereof and the estimates and assumptions that underlie them are based on matters as they exist as of the date of their preparation and not as of any future date, and will not be updated or otherwise revised to reflect information that subsequently becomes available, or circumstances existing or changes occurring after the date hereof, including changes in general economic or industry conditions, except as may be required by applicable law. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. New risks and uncertainties arise over time, and it is not possible for the Company to predict those events or how they may affect the Company. 2019 J.P.
