Exhibit 4.3



Description of Registrant’s Securities
The summary of the general terms and provisions of the registered securities of Dynatrace, Inc. (“Dynatrace,” “we,” or “our”) set forth below does not purport to be complete and is subject to and qualified in its entirety by reference to our Amended and Restated Certificate of Incorporation (our “certificate of incorporation”) and our Amended and Restated By-laws (our “bylaws”), each of which is incorporated by reference as an exhibit to this Annual Report on Form 10-K filed with the Securities and Exchange Commission. We encourage you to read our certificate of incorporation and bylaws and the applicable provisions of the General Corporation Law of the State of Delaware (the “DGCL”) for additional information.
General
Our authorized capital stock consists of 650,000,000 shares of capital stock, $0.001 par value per share, of which:
•600,000,000 shares are designated as common stock; and
•50,000,000 shares are designated as preferred stock.
Only our common stock is registered under Section 12 of the Securities Exchange Act of 1934, as amended. Our common stock is listed on the New York Stock Exchange under the symbol “DT”.
Common Stock
Dividend Rights
Subject to preferences that may apply to any shares of preferred stock outstanding at the time, and any contractual limitations, such as those in our credit agreements, the holders of our common stock are entitled to receive dividends out of funds then legally available, if any, if our board of directors, in its discretion, determines to issue dividends and then only at the times and in the amounts that our board of directors may determine.
Voting Rights
The holders of our common stock are entitled to one vote per share. Our common stock votes as a single class on all matters relating to the election and removal of directors on our board of directors and as provided by law. Our stockholders do not have the ability to cumulate votes for the election of directors. Except in respect of matters relating to the election of directors, or as otherwise provided in our charter or required by law, all matters to be voted on by our stockholders must be approved by a majority of the shares present in person or by proxy at the meeting and entitled to vote on the subject matter. In the case of the election of directors, director candidates must be approved by a plurality of the shares present in person or by proxy at the meeting and entitled to vote on the election of directors.
Other Rights
If we become subject to a liquidation, dissolution or winding-up, the assets legally available for distribution to our stockholders would be distributable ratably among the holders of our common stock and any participating preferred stock outstanding at that time, subject to prior satisfaction of all outstanding debt and liabilities and the preferential rights and payment of liquidation preferences, if any, on any outstanding shares of preferred stock.
Preferred Stock
No shares of our preferred stock are currently outstanding. Pursuant to our charter, our board of directors has the authority, without further action by the stockholders, to issue from time to time shares of 






preferred stock in one or more series. Our board of directors may designate the rights, preferences, privileges and restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, redemption rights, liquidation preference, sinking fund terms, and the number of shares constituting any series or the designation of any series. The issuance of preferred stock could have the effect of restricting dividends on our common stock, diluting the voting power of our common stock, impairing the liquidation rights of our common stock, or delaying, deterring or preventing a change in control. Such issuance could have the effect of decreasing the market price of our common stock. Any preferred stock so issued may rank senior to our common stock with respect to the payment of dividends or amounts upon liquidation, dissolution or winding up, or both. We currently have no plans to issue any shares of preferred stock.
Anti-Takeover Provisions in Our Charter and Bylaws
Certain provisions of our charter and bylaws may have the effect of delaying, deferring or discouraging another person from attempting to acquire control of us. These provisions, which are summarized below, may discourage takeovers, coercive or otherwise. These provisions are also geared, in part, towards encouraging persons seeking to acquire control of us to negotiate first with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us because negotiation of these proposals could result in an improvement of their terms.
Board Size; Board of Directors Vacancies; Directors Removed Only for Cause.     Our charter and bylaws allow Thoma Bravo to set the size of our board of directors and fill any vacancy on our board of directors, including newly created seats, for so long as Thoma Bravo beneficially owns at least 30% of the outstanding shares of our common stock. Upon Thoma Bravo ceasing to own at least 30% of the outstanding shares of our common stock, only our board of directors will be allowed to fill vacant directorships. In addition, (i) prior to the first date on which Thoma Bravo ceases to beneficially own at least 30% of the voting power of our then outstanding capital stock entitled to vote generally in the election of directors, our directors may be removed with or without cause upon the affirmative vote of Thoma Bravo and (ii) on and after such date on which Thoma Bravo ceases to beneficially own at least 30% of the voting power of our then outstanding capital stock entitled to vote generally in the election of directors, directors may only be removed for cause and only upon the affirmative vote of the holders of 66 2/3% or more of our outstanding shares of capital stock then entitled to vote at a meeting of our stockholders called for that purpose. In the event Thoma Bravo ceases to beneficially own at least 30% of the voting power of our then outstanding capital stock entitled to vote generally in the election of directors, directors previously nominated by Thoma Bravo would be entitled to serve the remainder of their respective terms, unless they are otherwise removed for cause in accordance with the terms of our charter. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control or management of our company. In addition, following the date on which Thoma Bravo ceases to beneficially own at least 30% of the outstanding shares of our common stock, the number of directors constituting our board of directors will be permitted to be set only by a resolution adopted by a majority vote of our entire board of directors. These provisions would prevent a stockholder from increasing the size of our board of directors and then gaining control of our board of directors by filling the resulting vacancies with its own nominees. This will make it more difficult to change the composition of our board of directors and will promote continuity of management.
Classified Board.     Our charter and bylaws provide that our board of directors is classified into three classes of directors, with each class serving three-year staggered terms. A third party may be discouraged from making a tender offer or otherwise attempting to obtain control of us as it is more 






difficult and time-consuming for stockholders to replace a majority of the directors on a classified board of directors.
Stockholder Action; Special Meeting of Stockholders.     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 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 certificate of incorporation provides otherwise. Our charter provides that so long as Thoma Bravo beneficially owns at least a majority of the outstanding shares of our common stock, any action required or permitted to be taken by our stockholders may be effected by written consent. Our charter provides that, after Thoma Bravo ceases to beneficially own at least a majority of the outstanding shares of our common stock, our stockholders may not take action by written consent but may only take action at annual or special meetings of our stockholders. As a result, a holder controlling a majority of our capital stock after Thoma Bravo no longer owns at least a majority of the outstanding shares of our common stock would not be able to amend our bylaws or remove directors without holding a meeting of our stockholders called in accordance with our bylaws. Our charter provides that special meetings of the stockholders may be called only upon a resolution approved by a majority of the total number of directors that we would have if there were no vacancies, the chairman of our board of directors, the Chief Executive Officer or the President, or, prior to the date that Thoma Bravo ceases to beneficially own at least a majority of the voting power of our then outstanding capital stock entitled to vote generally in the election of directors, at the request of the holders of a majority of the voting power of our then outstanding shares of voting capital stock. These provisions might delay the ability of our stockholders to force consideration of a proposal or for stockholders controlling a majority of our capital stock to take any action, including the removal of directors.
Advance Notice Requirements for Stockholder Proposals and Director Nominations.     Our bylaws provide advance notice procedures for stockholders seeking to bring business before our annual meeting of stockholders or to nominate candidates for election as directors at our annual meeting of stockholders. Our bylaws specify certain requirements regarding the form and content of a stockholder’s notice. Our bylaws prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting. Our bylaws also provide that nominations of persons for election to our board of directors may be made at a special meeting of stockholders at which directors are to be elected pursuant to the notice of meeting (i) by or at the direction of our board of directors or (ii) provided that our board of directors has determined that directors shall be elected at such meeting, by any stockholder who (a) is a stockholder of record both at the time the notice is delivered and on the record date for the determination of stockholders entitled to vote at the special meeting, (b) is entitled to vote at the meeting and upon such election and (c) complies with the notice procedures set forth in our bylaws. These provisions might preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders 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 our company. These provisions will not apply to nominations of candidates for elections as directors by Thoma Bravo.
No Cumulative Voting.     The DGCL provides that stockholders are not entitled to cumulate votes in the election of directors unless a corporation’s certificate of incorporation provides otherwise. Our charter does not provide for cumulative voting.






Amendment of Charter Provisions and Bylaws.     Our charter provides that prior to the date that Thoma Bravo ceases to beneficially own a majority of the voting power of our then outstanding capital stock entitled to vote generally in the election of directors (the “Trigger Date”), our bylaws may be adopted, amended, altered or repealed by the vote of a majority of the voting power of our then outstanding voting capital stock, voting together as a single class. After the Trigger Date, our charter and bylaws may be adopted, amended, altered or repealed by either (i) a vote of a majority of the total number of directors that the company would have if there were no vacancies or (ii) in addition to any other vote otherwise required by law, the affirmative vote of the holders of at least 75% of the voting power of our then outstanding capital stock entitled to vote generally in the election of directors, voting together as a single class; provided, that if the directors recommend that the stockholders approve such amendment or repeal, then the bylaws may be amended or repealed by the vote of a majority of the voting power of our then outstanding voting capital stock, voting together as a single class.
Our charter also provides that following the Trigger Date, the provisions of our charter relating to the size and composition of our board of directors, limitation on liabilities of directors, stockholder action by written consent, the ability of stockholders to call special meetings, business combinations with interested persons, amendment of our bylaws or charter and the Court of Chancery of the State of Delaware as the exclusive forum for certain disputes, may only be amended, altered, changed or repealed by the affirmative vote of the holders of at least 66 2/3% of the voting power of all of our outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class. Prior to the Trigger Date, such provisions may be amended, altered, changed or repealed by the affirmative vote of the holders of a majority of the voting power of our then outstanding capital stock entitled to vote generally in the election of directors, voting together as a single class. Our charter also provides that the provision of our charter that deals with corporate opportunity may only be amended, altered or repealed by a vote of 80.0% of the voting power of our then outstanding capital stock entitled to vote generally in the election of directors, voting together as a single class. See “—Corporate Opportunity.”
Issuance of Undesignated Preferred Stock.     Our board of directors has the authority, without further action by our stockholders, to designate and issue shares of preferred stock with rights and preferences, including super voting, special approval, dividend or other rights or preferences on a discriminatory basis. The existence of authorized but unissued shares of undesignated preferred stock would enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or other means.
Business Combinations with Interested Stockholders.     We have elected in our charter not to be subject to Section 203 of the DGCL, an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination, such as a merger, with an interested stockholder (i.e., a person or group owning 15% or more of the corporation’s voting capital stock) 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 not subject to any anti-takeover effects of Section 203 of the DGCL. However, our charter contains provisions that have the same effect as Section 203, except that they provide that sales of common stock to or by Thoma Bravo will be deemed to have been approved by our board of directors, and thereby not subject to the restrictions set forth in our charter that have the same effect as Section 203 of the DGCL.
Corporate Opportunity.    Messrs. Boro and Virnig, managing partners of Thoma Bravo, and Messrs. Lines and Zuber, operating partners of Thoma Bravo, currently serve on our board of directors 






and will continue to serve as directors following completion of this offering. Thoma Bravo, as the ultimate general partner of the Thoma Bravo Funds, will continue to beneficially own a majority of our outstanding common stock upon the completion of this offering. Thoma Bravo may beneficially hold equity interests in entities that directly or indirectly compete with us, and companies in which it currently invests may begin competing with us. As a result of these relationships, when conflicts between the interests of Thoma Bravo, on the one hand, and of other stockholders, on the other hand, arise, these directors may not be disinterested. Although our directors and officers have a duty of loyalty to us under the DGCL and our charter, transactions that we enter into in which a director or officer has a conflict of interest are generally permissible so long as (i) the material facts relating to the director’s or officer’s relationship or interest as to the transaction are disclosed to our board of directors and a majority of our disinterested directors approved the transactions, (ii) the material facts relating to the director’s or officer’s relationship or interest are disclosed to our stockholders and a majority of our disinterested stockholders approve the transaction or (iii) the transaction is otherwise fair to us.
Our charter provides that no officer or director of our company who is also a principal, officer, director, member, manager, partner, employee and/or independent contractor of Thoma Bravo will be liable to us or our stockholders for breach of any fiduciary duty by reason of the fact that any such individual pursues or acquires a corporate opportunity for its own account or the account of an affiliate, as applicable, instead of us, directs a corporate opportunity to Thoma Bravo instead of us or does not communicate information regarding a corporate opportunity to us. Our charter also provides that any principal, officer, director, member, manager, partner, employee and/or independent contractor of Thoma Bravo or any entity that controls, is controlled by or under common control with Thoma Bravo or any investment funds advised by Thoma Bravo will not be required to offer any transaction opportunity of which they become aware to us and could take any such opportunity for themselves or offer it to other companies in which they have an investment.
This provision may not be modified without the affirmative vote of the holders of at least 80.0% of the voting power of all of our outstanding shares of common stock.
Section 203 of the Delaware General Corporation Law
We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this stockholder becomes an interested stockholder, unless the business combination is approved in a prescribed manner. Under Section 203, a business combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:
		
	•
	before the stockholder became interested, our board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;


		
	•
	upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, shares owned by persons who are directors and also officers, and employee stock plans, in some instances, but not the outstanding voting stock owned by the interested stockholder; or


		
	•
	at or after the time the stockholder became interested, the business combination was approved by our board of directors and authorized at an annual or special meeting of the stockholders by the 








affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.
Section 203 defines a business combination to include:
		
	•
	any merger or consolidation involving the corporation and the interested stockholder;


		
	•
	any sale, transfer, lease, pledge or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;


		
	•
	subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;


		
	•
	subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; and


		
	•
	the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges, or other financial benefits provided by or through the corporation.


In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.
