Description of the Registrants Securities Registered Pursuant to Section 12 of the Securities Exchange Act of 1934, as amended

Exhibit 4.3

​

DESCRIPTION OF SECURITIES

As of December 31, 2021, Enfusion, Inc. (“Enfusion,” “we,” “our” or “us”) had one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended, or the Exchange Act): our Class A common stock, $0.001 per share. The following descriptions are summaries of the material terms of our amended and restated certificate of incorporation and amended and restated bylaws. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description of the matters set forth in this Exhibit 4.3, you should refer to our amended and restated certificate of incorporation, amended and restated bylaws, and registration rights agreement, or the RRA, which are included as exhibits to the Annual Report on Form 10-K of which this Exhibit 4.3 forms a part, and to the applicable provisions of Delaware law. We refer in this Exhibit 4.3 to our amended and restated certificate of incorporation as our certificate of incorporation, and we refer to our amended and restated bylaws as our bylaws.

General

Our authorized capital stock consists of 1,000,000,000 shares of Class A common stock, par value $0.001 per share, 150,000,000 shares of Class B common stock, par value $0.001 per share and 100,000,000 shares of preferred stock, par value $0.001 per share, all of which shares of preferred stock are undesignated.

Common Stock

Class A common stock

In general, 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. Our board of directors is divided into three classes with staggered three-year terms.

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 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 are entitled to receive pro rata our remaining assets available for distribution.

All of the outstanding shares of our Class A common stock are fully paid and non-assessable. The Class A common stock is not 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.

Class B common stock

Each share of our Class B common stock entitles its holder to one vote on all matters to be voted on by stockholders generally. Holders of shares of our Class B common stock vote together with holders of our Class A common stock 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 and Class B common stock to vote separately as different classes 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 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 we are entitled to issue and that the holders of Class B common stock would otherwise have with respect to an amendment to the certificate of incorporation increasing or decreasing the number of shares of Class B common stock we are 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 either Class A common stock or Class B common stock that we are authorized to issue would require a vote of a majority of the outstanding voting power of all capital stock (including both the Class A common stock and the Class B common stock), voting together as a single class.

Holders of our Class B common stock do not have any right to receive dividends or to receive a distribution upon a liquidation, dissolution or winding up of Enfusion, Inc. Shares of Class B common stock are not convertible into or exchangeable for shares of Class A common stock or any other security.

Shares of Class B common stock may be transferred to any transferee (other than to us) only if, and only to the extent permitted by our Seventh Amended and Restated Operating Agreement, such holder also simultaneously transfers an equal number of such holder’s Common Units to such transferee.

Preferred Stock

Our board of directors has the authority, without further action by our stockholders, to issue up to 100,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting, or the designation of, such series, any or all of which may be greater than the rights of Class A common stock. The issuance of our preferred stock could adversely affect the voting power of holders of Class A common stock and the likelihood that such holders will receive dividend payments and payments upon our liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change in control of

our company or other corporate action. No shares of preferred stock are outstanding, and we have no present plan to issue any shares of preferred stock.

Registration Rights

Certain holders of our common stock are entitled to rights with respect to the registration of these securities under the Securities Act of 1933, as amended, or the Securities Act. These rights are provided under our RRA. Our RRA includes demand registration rights, Form S-3 registration rights and piggyback registration rights. All fees, costs and expenses of underwritten registrations under the RRA will be borne by us and all selling expenses, including underwriting discounts and selling commissions, will be borne by the holders of the shares being registered.

Demand Registration Rights

Certain holders of our common stock are entitled to demand registration rights. At any time beginning 180 days after the effective date of our registration statement for our initial public offering, the FTV Investors, the ICONIQ Investors, the ELL Investors and any of their successors in interest thereof, or the Founders (in each case as defined in the RRA), subject to certain exceptions, can request that we register the offer and sale of their shares as long as such registration would cover at least 10% of the shares registrable under our RRA (or if less, all of the registrable securities of such holders). We are obligated to effect only one such registration if requested by certain holders of our common stock and only two such registrations from the holders of registrable securities as a group. If we determine that it would be materially detrimental to us and our stockholders to effect such a demand registration, we have the right to defer such registration, not more than once in any 12-month period, for a period of up to 90 days. Additionally, we will not be required to effect a demand registration during the period beginning 60 days prior to our good faith estimate of the date of the filing of, and ending on a date 180 days following the effectiveness of, an Enfusion-initiated registration statement relating to the public offering of our common stock.

Form S-3 Registration Rights

Certain holders of our common stock are entitled to certain Form S-3 registration rights. Such holders under our RRA may make a written request that we register the offer and sale of their shares on a registration statement on Form S-3 if we are eligible to file a registration statement on Form S-3, so long as the request covers securities the anticipated aggregate public offering price of which is at least $500,000, net of selling expenses. We are obligated to effect only two such registrations per year if requested by certain holders of our common stock and only two such registrations per year from the holders of registrable securities as a group. However, we will not be required to effect a registration on Form S-3 if we have effected one such registration within the 6-month period preceding the date of the request. If we determine that it would be materially detrimental to us and our stockholders to effect such a registration, we have the right to defer such registration, not more than once in any 12-month period, for a period of up to 90 days. Additionally, we will not be required to effect a Form S-3 registration during the period that is 60 days prior to our good faith estimate of the date of the filing of, and ending on a date 180 days following the effectiveness of, an Enfusion-initiated registration statement relating to the public offering of our common stock.

Piggyback Registration Rights

If we propose to register the offer and sale of our common stock under the Securities Act, in connection with the public offering of such common stock, certain holders of our common stock will be entitled to certain “piggyback” registration rights allowing the holders to include their shares in such registration, subject to certain marketing and other limitations. As a result, whenever we propose to file a registration statement under the Securities Act, other than with respect to (i) a registration relating to the sale of securities to our employees or employees of a subsidiary pursuant to a stock option, stock purchase, or similar plan; (ii) a registration relating to an SEC Rule 145 transaction; (iii) a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the registrable securities; or (iv) a registration in which the only common stock being registered is common stock issuable upon conversion of debt securities that are also being registered, the holders of these shares are entitled to notice of the registration and have the right, subject to certain limitations, to include their shares in the registration.

Indemnification

Our RRA contains customary cross-indemnification provisions, under which we are obligated to indemnify each selling stockholder, each underwriter of the shares being registered and each other person, if any, who controls such selling stockholder or underwriter within the meaning of the Securities Act or Exchange Act for losses, claims, damages or liabilities, joint or several, and any legal or other expenses reasonably incurred, arising from or based upon any untrue statement or alleged untrue statement of a material fact contained in any registration statement, any omission or alleged omission to state a material fact in any registration statement or necessary to make the statements therein not misleading, or any violation or alleged violation by the indemnifying party of securities laws, subject to certain exceptions.

Expiration of Registration Rights

The registration rights granted under our RRA will terminate on the earliest of (i) October 25, 2026, (ii) the consummation of a sale event, (iii) with respect to any particular stockholder, when such stockholder is able to sell all of its shares pursuant to Rule 144 or any similar exemption under the Securities Act during any three-month period without registration, or (iv) the closing of any merger or other transaction in which all of our outstanding shares are exchanged for securities registered under the Exchange Act.

Anti-Takeover Provisions

Our certificate of incorporation and bylaws include a number of provisions that may have the effect of delaying, deferring or preventing another party from acquiring control of us. These provisions, which are summarized below, are also designed to encourage persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our board of directors rather than pursue non-negotiated takeover attempts. 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 Composition and Filling Vacancies

Our certificate of incorporation provides for the division of our board of directors into three classes serving staggered three-year terms, with one class being elected each year. Our certificate of incorporation provides that directors may be removed only for cause and then only by the affirmative vote of the holders of at least two-thirds or more of the shares then entitled to vote at an election of directors. Furthermore, any vacancy on our board of directors, however occurring, including a vacancy resulting from an increase in the size of our board, may only be filled by the affirmative vote of a majority of our directors then in office even if less than a quorum. The classification of directors, together with the limitations on removal of directors and treatment of vacancies, has the effect of making it more difficult for stockholders to change the composition of our board of directors.

No Written Consent of Stockholders

Our certificate of incorporation provides that all stockholder actions are required to be taken by a vote of the stockholders at an annual or special meeting, and that stockholders may not take any action by written consent in lieu of a meeting. This limit may lengthen the amount of time required to take stockholder actions and would prevent the amendment of our bylaws or removal of directors by our stockholders without holding a meeting of stockholders.

Meetings of Stockholders

Our certificate of incorporation and bylaws provide that only a majority of the members of our board of directors then in office may call special meetings of stockholders and only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders. Our bylaws limit the business that may be conducted at an annual meeting of stockholders to those matters properly brought before the meeting.

Advance Notice Requirements

Our bylaws establish advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of stockholder proposals must be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, 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 annual meeting for the preceding year. Our bylaws specify the requirements as to form and content of all stockholders’ notices. These requirements may preclude stockholders from bringing matters before the stockholders at an annual or special meeting.

Amendment to Certificate of Incorporation and Bylaws

Our certificate of incorporation provides that any amendment thereof must first be approved by a majority of our board of directors, and if required by law or our certificate of incorporation, must thereafter be approved by a majority of the outstanding shares entitled to vote on the amendment and a majority of the outstanding shares of each class entitled to vote thereon as a class, except that the amendment of the provisions relating to stockholder action, board composition, limitation of liability and the amendment of our bylaws and certificate of incorporation must be

approved by not less than two-thirds of the outstanding shares entitled to vote on the amendment, and not less than two-thirds of the outstanding shares of each class entitled to vote thereon as a class.

Our bylaws provide that any amendment thereof must be approved by the affirmative vote of a majority of the directors then in office, subject to any limitations set forth in the bylaws; and may also be amended by the affirmative vote of not less than two-thirds of the outstanding shares entitled to vote on the amendment, voting together as a single class.

Undesignated Preferred Stock

Our certificate of incorporation provides for 100,000,000 authorized shares of preferred stock. The existence of authorized but unissued shares of preferred stock may enable our board of directors to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise. For example, if in the due exercise of its fiduciary obligations, our board of directors were to determine that a takeover proposal is not in the best interests of our stockholders, our board of directors could cause shares of preferred stock to be issued without stockholder approval in one or more private offerings or other transactions that might dilute the voting or other rights of the proposed acquirer or insurgent stockholder or stockholder group. In this regard, our certificate of incorporation grants our board of directors broad power to establish the rights and preferences of authorized and unissued shares of preferred stock. The issuance of shares of preferred stock could decrease the amount of earnings and assets available for distribution to holders of shares of Class A common stock. The issuance may also adversely affect the rights and powers, including voting rights, of these holders and may have the effect of delaying, deterring or preventing a change in control of us.

Choice of Forum

Our bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Chancery Court does not have jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) will be the sole and exclusive forum for state law claims for; (i) any derivative action or proceeding brought on our behalf: (ii) any action asserting a claim of, or a claim based on, a breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders; (iii) any action asserting a claim against us, or any current or former director, officer, or other employee or stockholder, arising out of or pursuant to any provision of the General Corporation Law of the State of Delaware or our certificate of incorporation or bylaws; (iv) any action to interpret, apply, enforce or determine the validity of our certificate of incorporation or bylaws; or (v) any action asserting a claim against us or any current or former director or officer or other employee governed by the internal affairs doctrine; provided, however, that this choice of forum provision does not apply to any causes of action arising under the Securities Act or the Exchange Act. Our bylaws further provide that, unless we consent in writing to an alternative forum, the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. Our bylaws also provide that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of and to have consented to this choice of forum provision. We recognize that the forum selection clause that is in our bylaws may impose additional litigation costs on stockholders in pursuing any such claims, particularly if the stockholders do not reside in or near the State of Delaware. Additionally, the forum selection clause that is in our bylaws may limit our

stockholders’ ability to bring a claim in a judicial forum that they find favorable for disputes with us or our directors, officers or employees, which may discourage such lawsuits against us and our directors, officers and employees even though an action, if successful, might benefit our stockholders. In addition, while the Delaware Supreme Court ruled in March 2020 that federal forum selection provisions purporting to require claims under the Securities Act be brought in federal court are “facially valid” under Delaware law, there is uncertainty as to whether other courts will enforce our Federal Forum Provision. If the Federal Forum Provision is found to be unenforceable in an action, we may incur additional costs associated with resolving such an action. The Federal Forum Provision may also impose additional litigation costs on stockholders who assert that the provision is not enforceable or invalid. The Court of Chancery of the State of Delaware or the federal district courts of the United States may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments may be more or less favorable to us than our stockholders.

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:

Section 203 defines a business combination to include:

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.
