Description of Registrants securities

The following description summarizes the most important terms of our capital stock. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description, you should refer to our restated certificate of incorporation, restated bylaws, and our amended and restated investors’ rights agreement (“IRA”), which are included as exhibits to this Annual Report on Form 10-K, of which this Exhibit 4.2 is a part, and to the applicable provisions of Delaware law.

Our authorized capital stock consists of 1,500,000,000 shares of our Class A common stock, $0.0001 par value per share, 300,000,000 shares of our Class B common stock, $0.0001 par value per share, and 50,000,000 shares of undesignated preferred stock, $0.0001 par value per share.

Subject to preferences that may apply to any shares of convertible preferred stock outstanding at the time, the holders of shares of our common stock are entitled to receive dividends out of funds legally available 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.

Holders of shares of our Class A common stock are entitled to one vote for each share of Class A common stock held on all matters submitted to a vote of stockholders and holders of our Class B common stock are entitled to 20 votes for each share of Class B common stock held on all matters submitted to a vote of stockholders. Holders of shares of our Class A common stock and Class B common stock vote together as a single class on all matters (including the election of directors) submitted to a vote of stockholders, unless, otherwise required by Delaware law or our restated certificate of incorporation. Delaware law could require either holders of our Class A common stock or Class B common stock to vote separately as a single class in the following circumstances:

•if we were to seek to amend our restated certificate of incorporation to increase or decrease the par value of a class of our capital stock, then that class would be required to vote separately to approve the proposed amendment; and

•if we were to seek to amend our restated certificate of incorporation in a manner that alters or changes the powers, preferences, or special rights of a class of our capital stock in a manner that affected its holders adversely, then that class would be require to vote separately to approve the proposed amendment.

We have not provided for cumulative voting for the election of directors in our restated certificate of incorporation. Accordingly, holders of a majority of the shares of our common stock will be able to elect all of our directors.

Our common stock is not entitled to preemptive rights, and is not subject to redemption or sinking fund provisions.

Upon our 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 of and the payment of liquidation preferences, if any, on any outstanding shares of preferred stock.

Each share of our Class B common stock is convertible into one share of our Class A common stock at any time and will convert automatically upon certain transfers and upon the earlier of (i) the date specified by a vote of the holders of 66 2/3% of the then outstanding shares of Class B common stock, (ii) seven years from June 29, 2021, (iii) the first date following July 2, 2021 which the number of shares of outstanding Class B common stock (including shares of Class B common stock subject to outstanding stock options) held by Tomer Weingarten, including certain permitted entities that Mr. Weingarten controls, is less than 25% of the number of shares of Class B common stock (including shares of Class B common stock subject to outstanding stock options) that Mr. Weingarten originally held as of June 29, 2021, (iv) the date fixed by our board of directors, following July 2, 2021 when Mr. Weingarten is no longer providing services to us as an officer, employee, consultant or member of our board of directors, (v) the date fixed by our board of directors following the date, if applicable, on which Mr. Weingarten is terminated for cause, as defined in our restated certificate of incorporation, and (vi) the date that is 12 months after the death or disability, as defined in our restated certificate of incorporation, of Mr. Weingarten.

Certain holders of shares of our Class B common stock and our Class A common stock or their permitted transferees are entitled to rights with respect to the registration of these shares under the Securities Act. These rights are provided under the terms of our IRA, and include demand registration rights, Form S-3 registration rights and piggyback registration rights. In any registration made pursuant to our IRA, all fees, costs and expenses of underwritten registrations will be borne by us and all selling expenses, including estimated underwriting discounts, selling commissions and stock transfer taxes, will be borne by the holders of the shares being registered.

The registration rights terminate (i) five years following the completion of our initial public offering, (ii) upon a deemed liquidation event, as defined in the IRA, or (iii) with respect to any particular stockholder who holds 1% or less of registrable securities (as defined in our IRA), at the time that such stockholder can sell all of its shares during any 90-day period pursuant to Rule 144 or another similar exemption under the Securities Act.

Certain holders of our common stock are entitled to demand registration rights. Under the terms of our IRA, we will be required, upon the written request of holders of at least 30% of the shares that are entitled to registration rights under our IRA, to register, as soon as practicable, all or a portion of these shares for public resale, if the aggregate price to the public of the shares offered is at least $10.0 million. We may postpone the filing of a registration statement once for up to 120 days in a 12-month period if our board of directors determines that the filing would be materially detrimental to us. We are not required to effect a demand registration under certain additional circumstances specified in our IRA, including at any time earlier than 180 days after the effective date of this offering.

Certain holders of our common stock are entitled to Form S-3 registration rights. The holders representing at least 30% of the then-outstanding shares having registration rights can request that we register all or part of their shares on Form S-3 if we are eligible to file a registration statement on Form S-3 and if the aggregate price to the public of the shares offered is at least $5.0 million. The holders may only require us to effect at most two registration statements on Form S-3 in any 12-month period. We may postpone the filing of a registration statement on Form S-3 no more than once during any 12-month period, for a period of not more than 120 days if our board of directors determines that the filing would be materially detrimental to us.

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 have the right to include their shares in the registration statement. However, this right does not apply to a registration relating to employee benefit plans, a registration relating to an SEC Rule 145 transaction, 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 our common stock, or 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 underwriters of any underwritten offering will have the right to limit the number of shares registered by these holders if they determine that marketing factors require limitation, in which case the number of shares to be registered will be apportioned pro rata among these holders, according to the total amount of securities entitled to be included by each holder. However, the number of shares to be registered by these holders cannot be reduced below 30% of the total shares covered by the registration statement, other than in the initial public offering.

The provisions of the DGCL, our restated certificate of incorporation, and our restated bylaws could have the effect of delaying, deferring or discouraging another person from acquiring control of our company. These provisions, which are summarized below, are expected to discourage certain types of coercive takeover practices and inadequate takeover bids and encourage persons seeking to acquire control of SentinelOne to first negotiate 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.

We are subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. 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 of 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.

Our restated certificate of incorporation and our restated bylaws include a number of provisions that may have the effect of deterring hostile takeovers, or delaying or preventing changes in control of our management team or changes in our board of directors or our governance or policy, including the following:

•Dual Class Common Stock. Our restated certificate of incorporation provides for a dual class common stock structure pursuant to which holders of our Class B common stock will have the ability to control the outcome of matters requiring stockholder approval, even if they own significantly less than a majority of the shares of our outstanding Class A and Class B common stock, including the election of directors and significant corporate transactions, such as a merger or other sale of our company or its assets. Current investors, executives, and employees will have the ability to exercise significant influence over those matters.

•Board of Directors Vacancies. Our restated certificate of incorporation and our restated bylaws authorize generally only our board of directors to fill vacant directorships resulting from any cause or created by the expansion of our board of directors. In addition, the number of directors constituting our board of directors may be set only by resolution adopted by a majority vote of our entire board of directors. These provisions prevent a stockholder from increasing the size of our board of directors and gaining control of our board of directors by filling the resulting vacancies with its own nominees.

•Classified Board. Our restated certificate of incorporation and our restated bylaws provide that our board of directors is classified into three classes of directors. The existence of a classified board of directors could delay a successful tender offeror from obtaining majority control of our board of directors, and the prospect of that delay might deter a potential offeror.

•Directors Removed Only for Cause. Our restated certificate of incorporation provides that stockholders may remove directors only for cause and only by the affirmative vote of the holders of at least two-thirds of the voting power of the then-outstanding capital stock.

•Supermajority Requirements for Amendments of Our Restated Certificate of Incorporation and Restated Bylaws. Our restated certificate of incorporation further provides that the affirmative vote of holders of at least two-thirds of the voting power of all of the then outstanding shares of capital stock will be required to amend certain provisions of our restated certificate of incorporation, including provisions relating to the classified board, the size of our board of directors, removal of directors, special meetings, actions by written consent and designation of our preferred stock, provided that if two-thirds of our board of directors has approved the amendment or repeal of certain provisions of our restated certificate of incorporation, then only the affirmative vote of a majority of the voting power of all of the then outstanding shares of capital stock shall be required to amend or repeal such provisions of our restated certificate of incorporation. In addition, the affirmative vote of holders of 75% of the voting power of each of our Class A common stock and Class B common stock, voting separately by class, will be required to amend the provisions of our restated certificate of incorporation relating to the terms of our Class A or Class B common stock. The affirmative vote of holders of at least two-thirds (2/3) of the voting power of all of the then outstanding shares of capital stock will be required to amend or repeal our restated bylaws, although our restated bylaws may be amended by a simple majority vote of our board of directors. Additionally, in the case of any proposed adoption, amendment, or repeal of any provisions of the restated bylaws that is approved by our board of directors and submitted to the stockholders for adoption, if two-thirds of our board of directors has approved such adoption, amendment, or repeal of any provisions of our restated bylaws, then only the affirmative vote of a majority of the voting power of all of the then outstanding shares of capital stock shall be required to adopt, amend, or repeal any provision of our restated bylaws.

•Stockholder Action; Special Meetings of Stockholders. Our restated certificate of incorporation provides that 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, holders of our capital stock would not be able to amend our restated bylaws or remove directors without holding a meeting of our stockholders called in accordance with our restated bylaws. Our restated certificate of incorporation and our restated bylaws will provide that special meetings of our stockholders may be called only by a majority of our board of directors, the chairman of our board of directors or our chief executive officer, thus prohibiting a stockholder from calling a special meeting. These provisions might delay the ability of our stockholders to force consideration of a proposal or for stockholders to take any action, including the removal of directors.

•Advance Notice Requirements for Stockholder Proposals and Director Nominations. Our restated 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 restated bylaws also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders. We expect that these provisions might 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.

•No Cumulative Voting. The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless a corporation’s certificate of incorporation provides otherwise. Our restated certificate of incorporation and restated bylaws do not provide for cumulative voting.

•Issuance of Undesignated Preferred Stock. Our board of directors has the authority, without further action by the stockholders, to issue up to 50,000,000 shares of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by our board of directors. The existence of authorized but unissued shares of preferred stock enables 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 otherwise.

•Choice of Forum. In addition, our restated certificate of incorporation provides that, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware will be the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the DGCL, our restated certificate of incorporation or our restated bylaws; any action asserting a claim against us that is governed by the internal affairs doctrine; or any to interpret, apply, enforce, or determine the validity of the restated certificate of incorporation or restated bylaws. The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable. Our restated certificate of incorporation also provides that the federal district courts of the United States will, to the fullest extent permitted by law, be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, or the Federal Forum Provision. While there can be no assurance that federal or state courts will follow the holding of the Delaware Supreme Court which recently found that such provisions are facially valid under Delaware law or determine that the Federal Forum Provision should be enforced in a particular case, application of the Federal Forum Provision means that suits brought by our stockholders to enforce any duty or liability created by the Securities Act must be brought in federal court and cannot be brought in state court. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all claims brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. In addition, the Federal Forum Provision applies, to the fullest extent permitted by law, to suits brought to enforce any duty or liability created by the Exchange Act. Accordingly, actions by our stockholders to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder must be brought in federal court. Our stockholders will not be deemed to have waived our compliance with the federal securities laws and the regulations promulgated thereunder. Any person or entity purchasing or otherwise acquiring or holding any interest in any of our securities shall be deemed to have notice of and consented to our exclusive forum provisions, including the Federal Forum Provision. These provisions may limit a stockholder’s ability to bring a claim in a judicial forum of their choosing for disputes with us or our

directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers, and other employees.
