Description of the Registrants Securities registered pursuant to Section 12 of the Securities Exchange Act of 1934

Our authorized capital stock consists of 675,000,000 shares of common stock, par value $0.01 per share, and 10,000,000 shares of undesignated preferred stock, par value $0.01 per share.

Holders of our common stock are entitled:

to cast one vote for each share of common stock held of record on all matters submitted to a vote of the stockholders;

to receive, on a pro rata basis, dividends and distributions, if any, that our Board may declare out of legally available funds, subject to preferences that may be applicable to our preferred stock, if any, then outstanding; and

upon our liquidation, dissolution or winding up, to share equally and ratably in any assets remaining after the payment of all debt and other liabilities, subject to the prior rights, if any, of holders of any outstanding shares of preferred stock.

We do not currently expect to declare or pay dividends on our common stock for the foreseeable future. See “Dividend Policy.”

The holders of our common stock do not have any preemptive, cumulative voting, subscription, conversion, redemption or sinking fund rights. Our common stock is not subject to future calls or assessments by us. The rights and privileges of holders of our common stock are subject to any series of preferred stock that we may issue in the future, as described below.

The holders of our common stock are not entitled to vote on any amendments to our amended and restated certificate of incorporation that relate solely to the terms of one or more outstanding series of our preferred stock if the holders of such affected series are entitled, either separately or together with holders of one or more other such series, to vote thereon pursuant to our amended or restated certificate of incorporation or the DGCL.

Our common stock is listed on The Nasdaq Global Select Market under the symbol “CVET.”

Under our amended and restated certificate of incorporation, our Board has the authority, by resolution and without approval by our stockholders, to issue from time to time shares of preferred stock in one or more series and to fix the voting powers, designations, preferences and the relative participating, optional or other special rights and other terms and qualifications, limitations and restrictions of each series, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences and the number of shares constituting any series. No shares of our authorized preferred stock are outstanding. Because our Board has the power to establish the preferences and rights of the shares of any series of preferred stock, it may afford holders of any preferred stock preferences, powers and rights, including voting and dividend rights, senior to the rights of holders of our common stock, which could adversely affect the holders of our common stock and could delay, discourage or prevent a takeover of us even if a change of control of us would be beneficial to the interests of our stockholders.

Our amended and restated by-laws provide that annual stockholder meetings will be held at a date, time and place, if any, as selected by resolution adopted by a majority of our entire Board or, if duly authorized by the affirmative vote of a majority of our entire Board, by a committee thereof, or by the Chairman of our Board (if delegated such authority by resolution adopted by a majority of our entire Board). To the extent permitted under applicable law, we may conduct stockholder meetings by remote communications, including by webcast. Our amended and restated certificate of incorporation provides that the first annual stockholder meeting will take place in 2020.

The affirmative vote of holders of a majority of the outstanding shares of our capital stock present, in person or by proxy, at any annual or special meeting of stockholders and entitled to vote will decide all matters voted on by stockholders at such meeting, unless the question is one upon which, by express provision of law, under our amended and restated certificate of incorporation, or under our amended and restated by-laws, a different vote is required, in which case such provision will control.

The provisions of our amended and restated certificate of incorporation and amended and restated by-laws and of the DGCL summarized below may have an anti-takeover effect and may delay, deter or prevent a tender offer or takeover attempt that might be in a stockholder’s best interest, including an attempt that might result in the receipt of a premium over the market price for shares of our common stock. These provisions are also designed, in part, to encourage persons seeking to acquire control of us to first negotiate with our Board, which could result in an improvement of the terms of any offer.

Our amended and restated certificate of incorporation and amended and restated by-laws provide that a special meeting of stockholders may be called only by (i) the Chairman of our Board, (ii) a majority of our entire Board, (iii) our lead independent director or (iv) our Chief Executive Officer.

Our amended and restated certificate of incorporation provides that any action that may be taken at any meeting of stockholders may not be taken by written consent of stockholders in lieu of a meeting (except as may otherwise expressly be provided by the terms of any series of shares of preferred stock permitting the holders of such series to act by written consent).

Our amended and restated certificate of incorporation provides for a board of directors divided into three classes, serving staggered terms of one, two and three years, respectively (for the first three years following February 7, 2019 until the 2022 annual meeting of stockholders). The first class of directors, which is serving a one-year term expiring at the 2020 annual meeting of stockholders, includes two directors designated by Henry Schein and one director designated by Vets First Choice. The second class of directors, which is serving a two-year term expiring at the 2021 annual meeting of stockholders, includes two directors designated by Henry Schein and two directors designated by Vets First Choice. The third class of directors, which is serving a three-year term expiring at the 2022 annual meeting of stockholders, includes two directors designated by Henry Schein and two directors designated by Vets First Choice. Vacancies on our Board will be filled by our Board in accordance with our amended and restated by-laws.

In order to minimize the likelihood that an acquisition of our capital stock by one or more persons (or coordinating groups of persons) after the Distribution could be part of a plan or series of related transactions that includes the Distribution, our amended and restated certificate of incorporation generally prohibits, for the two-year period following the Distribution, direct or indirect beneficial ownership (taking into account applicable ownership provisions of the Code), and any agreement, understanding, or substantial negotiations to acquire beneficial ownership, by any person or persons of more than the applicable Ownership Limitation of our outstanding common stock or any other class or series of outstanding stock. A transfer for this purpose includes not only direct transfers, but also other direct and indirect changes in beneficial ownership. In addition, in general, the shares of beneficial interest owned by related or affiliated owners will be aggregated for purposes of the Ownership Limitation. Our Board may increase or decrease the relevant Ownership Limitation if it determines that such increase or decrease

is advisable to help us maintain the tax-free treatment of the Distribution under Section 355 of the Code and other conditions are met.

Any attempted transfer of our capital stock which, if effective, would result in violation of the relevant Ownership Limitation will be null and void ab initio, and will cause the number of shares causing the violation (rounded up to the nearest whole share) to be automatically transferred to a trust for the exclusive benefit of one or more charitable beneficiaries, and the proposed transferee will not acquire any rights in the shares. The automatic transfer will be deemed to be effective as of the close of business on the business day prior to the date of the transfer. We will designate a trustee of the trust that will not be affiliated with us. We will also name one or more charitable organizations as a beneficiary of the trust. Shares-in-trust will remain issued and outstanding shares. The trustee will receive all distributions on the shares-in-trust and will hold such distributions in trust for the exclusive benefit of the beneficiary. The trustee will vote all shares-in-trust during the period they are held in trust and, subject to Delaware law, will have the authority to rescind as void any vote cast by the proposed transferee prior to our discovery that the shares have been transferred to the trust and to recast the vote in accordance with the desires of the trustee acting for the benefit of the charitable beneficiary. To the fullest extent permitted by law, the transferee will be deemed to have consented to the trustee taking such actions.

The trustee of the trust will be empowered to sell the shares-in-trust to a qualified person selected by the trustee and to distribute to the applicable prohibited owner an amount equal to the lesser of (1) the sales proceeds received by the trust for such shares-in-trust or (2) (A) if the prohibited owner was a transferee for value, the price paid by the prohibited owner for such shares-in-trust or (B) if the prohibited owner was not a transferee or was a transferee but did not give value for the shares-in-trust, the market price on the day of the event causing the shares to be held in trust. The trustee may reduce the amount payable to the prohibited owner by the amount of dividends and other distributions that have been paid to the prohibited owner and are owed by the prohibited owner to the trustee. Any amount received by the trustee in excess of the amount to be paid to the prohibited owner will be distributed to the beneficiary of the trust. In the event that the shares-in-trust shall have been sold by the purported transferee in an open market transaction, such sale will be deemed to have been made on behalf of the trustee and all of the net profit, if any, from such sale shall be paid by the purported transferee to the trustee for the exclusive benefit of the charitable beneficiary. The purported transferee of the shares-in-trust will have no right to share in any profit that may be realized in respect of such shares.

Any person who acquires or attempts to acquire (or who enters into or attempts to enter into any agreement, understanding, arrangement or substantial negotiations to acquire) shares in violation of the foregoing restriction or who owns shares that were transferred to any such trust is required to give immediate written notice to us of such event. Such person shall provide to us such other information as we may request in order to determine the effect, if any, of such transfer on the qualification of the Distribution for its intended tax-free treatment under Section 355 of the Code and to ensure compliance with the relevant Ownership Limitation.

For so long as the ownership restriction is in effect, on or prior to January 31 of each calendar year, every person or persons who own five percent (5%) or more of the issued and outstanding shares of any class or series of our capital stock shall provide to us such information as we may reasonably request to determine the effect, if any, on such person or persons’ ownership of capital stock on the Distribution’s qualification for tax-free status under Section 355 of the Code and to ensure compliance with the relevant Ownership Limitation.

Our Board has the power to waive the relevant Ownership Limitation for specific transfers after following procedures set out in our amended and restated certificate of incorporation. However, other than in respect of certain transfers that meet certain requirements described in our amended and restated certificate of incorporation, our Board is not obligated to grant a waiver.

The ownership restriction is intended to help preserve the tax-free treatment of the Distribution under Section 355 of the Code, but it is possible the restriction could depress the price of shares of our common stock, and, in certain circumstances while the ownership restriction is in effect, could inhibit proxy contests to change our Board or delay, defer or prevent a transaction or a change in control of us that might involve a premium price for holders of our stock or that might otherwise be in the best interest of our stockholders.

Our amended and restated certificate of incorporation provides that directors may be removed only upon the affirmative vote of holders of at least two-thirds of the outstanding shares of our capital stock then entitled to vote and, until the 2022 annual meeting of stockholders, directors may be removed only for cause.

Our amended and restated by-laws include an advance notice procedure for stockholders to make nominations of candidates for election as directors before an annual or special meeting of our stockholders or to bring other business before an annual meeting of our stockholders. The amended and restated by-laws provide that any stockholder wishing to nominate persons for election as directors at, or bring other business before, a stockholder meeting must timely deliver to our secretary at our principal executive offices a written notice of the stockholder’s intention to do so. These provisions may have the effect of precluding the conduct of certain business at a stockholder meeting if the proper procedures are not followed. We expect that these provisions may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of us.

For annual meetings of stockholders, to be timely, the stockholder’s notice to nominate persons for election as directors or to bring other business must be delivered to our secretary at our principal executive offices no earlier than 120 days nor later than 90 days before the first anniversary date of the annual meeting for the preceding year; provided, however, that in the event that the annual meeting is set for a date that is more than 30 days before or more than 60 days after the first anniversary date of the preceding year’s annual meeting, a stockholder’s notice must be delivered to our Secretary no earlier than 120 days before the meeting and no later than the later of (x) 90 days prior to the meeting and (y) the tenth day following the day on which notice of the date of the annual meeting was mailed or a public announcement of the date of the such meeting is first made by us.

For special meetings of stockholders for the purpose of electing directors called pursuant to our amended and restated certificate of incorporation and amended and restated by-laws, to be timely, the stockholder’s notice to nominate persons for election as directors must be delivered to our secretary at our principal executive offices no earlier than 120 days before the special meeting and no later than the later of (x) 90 days prior to the meeting and (y) the tenth day following the day on which notice of the date of the special meeting was mailed or on which a public announcement of the date of the such meeting is first made by us (whichever occurs first).

Our amended and restated certificate of incorporation provides that it may be amended by the affirmative vote of the holders of at least two-thirds of the outstanding shares of our capital stock then entitled to vote at any annual or special meeting of stockholders.

In addition, our amended and restated certificate of incorporation and amended and restated by-laws provide that our by-laws may be amended, altered or repealed, or new by-laws may be adopted, by the affirmative vote of a majority of our entire Board (except to the extent our amended and restated by-laws require a different vote), or by the affirmative vote of the holders of at least two-thirds of the outstanding shares of our capital stock then entitled to vote.

These provisions make it more difficult for any person to remove or amend any provisions in our amended and restated certificate of incorporation and amended and restated by-laws that may have an anti-takeover effect.

We are governed by Section 203 of the DGCL. Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination, such as a merger, with a person or group owning 15% or more of the corporation’s outstanding voting stock (an “Interested Stockholder”) for a period of three years following the date the person became an Interested Stockholder, unless (with certain exceptions) the business combination or the transaction in which the person became an Interested Stockholder is approved in a prescribed manner. Accordingly, we are subject to the anti-takeover effects of Section 203.
