Description of Registrants Securities

Class A common stock, par value $0.01 per share, is the only class of securities of ZoomInfo Technologies Inc., a Delaware corporation, registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Class A common stock is listed on the Nasdaq under the symbol “ZI”. As used in this Exhibit 4.1, unless the context otherwise requires, references to “we,” “us,” “our,” the “Company,” “ZoomInfo” and similar references refer to ZoomInfo Technologies Inc., and not to any of its subsidiaries.

The following description of our Class A common stock is a summary and does not purport to be complete. It is subject to and qualified in its entirety by our amended and restated certificate of incorporation and amended and restated bylaws, each of which is incorporated by reference as an exhibit to the Annual Report on Form 10-K of which this Exhibit 4.1 is a part (the “Annual Report”), and the Delaware General Corporation Law (the “DGCL”). We encourage you to read the amended and restated certificate of incorporation, amended and restated bylaws and the applicable provisions of the DGCL, as well as our stockholders agreement and the registration rights agreement entered into in connection with our initial public offering of our Class A common stock (the “IPO”), both of which are incorporated by reference as exhibits to the Annual Report, for additional information. Capitalized terms used in this Exhibit 4.1 that are not defined herein are defined in the Annual Report.

Our authorized capital stock consists of 2,500,000,000 shares of Class A common stock, par value $0.01 per share, 500,000,000 shares of Class B common stock, par value $0.01 per share, 300,000,000 shares of Class C common stock, par value $0.01 per share, and 200,000,000 shares of preferred stock, par value $0.01 per share. After the consummation of the Reorganization, there are no issued and outstanding shares of Class B common stock or Class C common stock and we do not intend to issue any shares of Class B common stock or Class C common stock. No shares of preferred stock have been issued or are currently outstanding. Unless our board of directors determines otherwise, we will issue all shares of our capital stock in uncertificated form.

Holders of outstanding shares of our Class A common stock will vote as a single class on all matters on which stockholders are entitled to vote generally, except as otherwise required by law. Delaware law entitles the holders of the outstanding shares of Class A common stock to vote separately as a different class in connection with any amendment to our certificate of incorporation that would increase or decrease the par value of the shares of such class or that would alter or change the powers, preferences or special rights of such class so as to affect them adversely. As permitted by Delaware law, the amended and restated certificate of incorporation includes a provision which eliminates the class vote that the holders of Class A common stock would otherwise have with respect to an amendment to the certificate of incorporation increasing or decreasing the number of shares of Class A common stock the Company is entitled to issue. Thus, subject to any other voting requirements contained in the certificate of incorporation, any amendment to the certificate of incorporation increasing or decreasing the number of shares of Class A common stock that the Company is authorized to issue would require a vote of a majority of the outstanding voting power of all capital stock (including the Class A common stock), voting together as a single class.

Holders of shares of our Class A common stock are entitled to one vote for each share held of record on all matters on which stockholders are entitled to vote generally, including the election or removal of directors. The holders of our Class A common stock do not have cumulative voting rights in the election of directors.

Holders of shares of our Class A common stock are entitled to receive dividends at the same rate when, as and if declared by our board of directors out of funds legally available therefor, subject to any statutory or contractual restrictions on the payment of dividends and to the rights of the holders of one or more outstanding series of our preferred stock.

Upon our liquidation, dissolution, or winding up, and after payment in full of all amounts required to be paid to creditors, and subject to the rights of the holders of one or more outstanding series of preferred stock having liquidation preferences, the holders of shares of our Class A common stock will be entitled to receive pro rata our remaining assets available for distribution.

The Class A common stock is not be subject to further calls or assessments by us. Holders of shares of our Class A common stock do not have preemptive, subscription, redemption or conversion rights. There are no redemption or sinking fund provisions applicable to the Class A common stock. The rights, powers, preferences and privileges of holders of our Class A common stock are subject to those of the holders of any shares of our preferred stock or any other series or class of stock we may authorize and issue in the future.

Our amended and restated certificate of incorporation authorizes our board of directors to establish one or more series of preferred stock (including convertible preferred stock). Unless required by law or the Nasdaq, and subject to the terms of our amended and restated certificate of incorporation, the authorized shares of preferred stock will be available for issuance without further action by holders of our Class A common stock. Our board of directors is able to determine, with respect to any series of preferred stock, the powers (including voting powers), preferences and relative, participating, optional or other special rights, and the qualifications, limitations or restrictions thereof, including, without limitation:

•the designation of the series;

•the number of shares of the series, which our board of directors may, except where otherwise provided in any preferred stock designation, increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares then outstanding);

•whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series;

•the dates at which dividends, if any, will be payable on shares of such series;

•the redemption rights and price or prices, if any, for shares of the series;

•the terms and amounts of any sinking fund provided for the purchase or redemption of shares of the series;

•the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution, or winding-up of our affairs or other event;

•whether the shares of the series will be convertible into shares of any other class or series, or any other security, of us or any other entity, and, if so, the specification of the other class or series or other security, the conversion price or prices or rate or rates, any rate adjustments, the date or dates as of which the shares will be convertible and all other terms and conditions upon which the conversion may be made;

•restrictions on the issuance of shares of the same series or of any other class or series of our capital stock; and

•the voting rights, if any, of the holders of the series.

We could issue a series of preferred stock that could, depending on the terms of the series, impede or discourage an acquisition attempt or other transaction that some, or a majority, of the holders of our Class A common stock might believe to be in their best interests or in which the holders of our Class A common stock might receive a premium over the market price of the shares of our Class A common stock. Additionally, the issuance of preferred stock may adversely affect the rights of holders of our Class A common stock by restricting dividends on the Class A common stock, diluting the voting power of the Class A common stock or subordinating the rights of the Class A common stock to distributions upon a liquidation, dissolution, or winding up or other event. As a result of these or other factors, the issuance of preferred stock could have an adverse impact on the market price of our Class A common stock.

The DGCL permits a corporation to declare and pay dividends out of “surplus” or, if there is no “surplus,” out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. “Surplus” is defined as the excess of the net assets of the corporation over the amount determined to be the capital of the corporation by its board of directors. The capital of the corporation is typically calculated to be (and cannot be less than) the aggregate par value of all issued shares of capital stock. Net assets equals the fair value of the total assets minus total liabilities. The DGCL also provides that dividends may not be paid out of net profits if, after the payment of the dividend, the remaining capital would be less than the capital represented by the outstanding stock of all classes having a preference upon the distribution of assets. Declaration and payment of any dividend will be subject to the discretion of our board of directors.

Our amended and restated certificate of incorporation, amended and restated bylaws, and the DGCL contain provisions that are summarized in the following paragraphs and that are intended to enhance the likelihood of continuity and stability in the composition of our board of directors. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile or abusive change of control and enhance the ability of our board of directors to maximize stockholder value in connection with any unsolicited offer to acquire us. However, these provisions may have an anti-takeover effect and may delay, deter or prevent a merger or acquisition of the Company by means of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the prevailing market price for the shares of common stock held by stockholders.

The authorized but unissued shares of common stock and preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing standards of the Nasdaq. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could make more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Our amended and restated certificate of incorporation provides that, subject to the rights of holders of any series of preferred stock, our board of directors is divided into three classes of directors, as nearly equal in number as possible, and with the directors serving staggered three-year terms, with only one class of directors being elected at each annual meeting of stockholders. As a result, approximately one-third of our board of directors will be elected each year. The classification of directors has the effect of making it more difficult for stockholders to change the composition of our board of directors. Our amended and restated certificate of incorporation and amended and restated bylaws provide that, subject to any rights of holders of preferred stock to elect additional directors under specified circumstances, the number of directors will be fixed from time to time exclusively pursuant to a resolution adopted by the board of directors.

We have opted out of Section 203 of the DGCL; however, our amended and restated certificate of incorporation contains similar provisions providing that we may not engage in certain “business combinations” with any “interested stockholder” for a three-year period following the time that the stockholder became an interested stockholder, unless:

•prior to such time, our board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding certain shares; or

•at or subsequent to that time, the business combination is approved by our board of directors and by the affirmative vote of holders of at least 66⅔% of our outstanding voting stock that is not owned by the interested stockholder.

Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who, together with that person’s affiliates and associates, owns, or within the previous three years owned, 15% or more of our outstanding voting stock. For purposes of this section only, “voting stock” has the meaning given to it in Section 203 of the DGCL.

Under certain circumstances, this provision will make it more difficult for a person who would be an “interested stockholder” to effect various business combinations with us for a three-year period. This provision may encourage companies interested in acquiring us to negotiate in advance with our board of directors because the stockholder approval requirement would be avoided if our board of directors approves either the business combination or the transaction that results in the stockholder becoming an interested stockholder. These provisions also may have the effect of preventing changes in our board of directors and may make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Our amended and restated certificate of incorporation provides that our Sponsors and their affiliates and any of their respective direct or indirect transferees, and any group as to which such persons are a party, do not constitute “interested stockholders” for purposes of this provision.

Under the DGCL, unless otherwise provided in our amended and restated certificate of incorporation, directors serving on a classified board may be removed by the stockholders only for cause. Our amended and restated certificate of incorporation provides that the directors divided into classes may be removed with or without cause upon the affirmative vote of a majority in voting power of all outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class; provided, however, at any time when the parties to our stockholders agreement collectively beneficially own, in the aggregate, less than 50% of the voting power of all outstanding shares of our stock entitled to vote generally in the election of directors, directors may only be removed for cause, and only upon the affirmative vote of holders of at least 66⅔% of the voting power of all the then outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class. In addition, our amended and restated certificate of incorporation also provides that, subject to the rights granted to one or more series of preferred stock then outstanding or the rights granted under the stockholders agreement, any newly created directorship on the board of directors that results from an increase in the number of directors and any vacancies on our board of directors will be filled only by the affirmative vote of a majority of the remaining directors, even if less than a quorum, by a sole remaining director or by the stockholders; provided, however, at any time when the parties to our stockholders agreement collectively beneficially own, in the aggregate, less than 50% of voting power of the stock of the Company entitled to vote generally in the election of directors, any newly created directorship on the board of directors that results from an increase in the number of directors and any vacancy occurring in the board of directors may only be filled by a majority of the directors then in office, although less than a quorum, or by a sole remaining director (and not by the stockholders).

Under Delaware law, the right to vote cumulatively does not exist unless the certificate of incorporation specifically authorizes cumulative voting. Our amended and restated certificate of incorporation does not authorize cumulative voting. Therefore, stockholders holding a majority in voting power of the shares of our stock entitled to vote generally in the election of directors will be able to elect all of our directors.

Our amended and restated certificate of incorporation provides that special meetings of our stockholders may be called at any time only by or at the direction of the board of directors, the chairman of our board or the chief executive officer; provided, however, that at any time when a Sponsor beneficially owns, in the aggregate, at least 20% in voting power of the stock entitled to vote generally in the election of directors, special meetings of our stockholders shall also be called by the board of directors or the chairman of the board of directors at the request of such Sponsor. Our amended and restated bylaws prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting. These provisions may have the effect of deterring, delaying or discouraging hostile takeovers, or changes in control or management of the Company.

Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors. In order for any matter to be “properly brought” before a meeting, a stockholder will have to comply with advance notice requirements and provide us with certain information. Generally, to be timely, a stockholder’s notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the immediately preceding annual meeting of stockholders. Our amended and restated bylaws also specify requirements as to the form and content of a stockholder’s notice. These provisions do not apply to the parties to our stockholders agreement so long as the stockholders agreement remains in effect. Our amended and restated bylaws allow the chairman of the meeting at a meeting of the stockholders to adopt rules and regulations for the conduct of meetings which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed. These provisions may also defer, delay or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control of the Company.

Pursuant to Section 228 of the DGCL, any action required to be taken at any annual or special meeting of the stockholders may be taken without a meeting, without prior notice, and without a vote if a consent or consents in writing, setting forth the action so taken, is or are signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of our stock entitled to vote thereon were present and voted, unless our amended and restated certificate of incorporation provides otherwise. Our amended and restated certificate of incorporation does not permit our Class A common stockholders to act by consent in writing, unless such action is recommended by all directors then in office, at any time when the parties to our stockholders agreement collectively own, in the aggregate, less than 50% in voting power of our stock entitled to vote generally in the election of directors.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that the board of directors is expressly authorized to make, alter, amend, change, add to, rescind or repeal, in whole or in part, our bylaws without a stockholder vote in any matter not inconsistent with the laws of the State of Delaware or our amended and restated certificate of incorporation. At any time when the parties to our stockholders agreement collectively beneficially own, in the aggregate, less than 50% in voting power of our stock entitled to vote generally in the election of directors, any amendment, alteration, rescission or repeal of our bylaws by our stockholders requires the affirmative vote of the holders of at least 66⅔% in voting power of all the then outstanding shares of stock entitled to vote thereon, voting together as a single class.

The DGCL provides generally that the affirmative vote of a majority of the outstanding shares entitled to vote thereon, voting together as a single class, is required to amend a corporation’s certificate of incorporation, unless the certificate of incorporation requires a greater percentage. Our amended and restated certificate of incorporation provides that at any time when the parties to our stockholders agreement collectively beneficially own, in the aggregate, less than 50% in voting power of our stock entitled to vote generally in the election of directors, the following provisions in our amended and restated certificate of incorporation may be amended, altered, repealed or

rescinded only by the affirmative vote of the holders of at least 66⅔% in voting power of all the then outstanding shares of our stock entitled to vote thereon, voting together as a single class:

•the provision requiring a 66⅔% supermajority vote for stockholders to amend our amended and restated bylaws;

•the provisions providing for a classified board of directors (the election and term of our directors);

•the provisions regarding resignation and removal of directors;

•the provisions regarding competition and corporate opportunities;

•the provisions regarding entering into business combinations with interested stockholders;

•the provisions regarding stockholder action by written consent;

•the provisions regarding calling special meetings of stockholders;

•the provisions regarding filling vacancies on our board of directors and newly created directorships;

•the provisions eliminating monetary damages for breaches of fiduciary duty by a director;

•the provision regarding forum selection; and

•the amendment provision requiring that the above provisions be amended only with a 66⅔% supermajority vote.

The combination of the classification of our board of directors, the lack of cumulative voting and the supermajority voting requirements makes it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Because our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management.

These provisions may have the effect of deterring hostile takeovers or delaying or preventing changes in control of us or our management, such as a merger, reorganization or tender offer. These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of the Company. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions are also intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions may also have the effect of preventing changes in management.
