Exhibit 4.2

SHAKE SHACK INC.

DESCRIPTION OF SECURITIES REGISTERED UNDER SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934

    The Class A common stock, par value $0.001 per share (“Class A Common Stock”) of Shake Shack Inc. is listed on the New York Stock Exchange under the symbol “SHAK” and is registered under Section 12 of the Securities Exchange Act of 1934. All outstanding shares of Class A Common Stock are validly issued, fully paid and nonassessable.

    The following description of the terms of our common stock is not complete and is qualified in its entirety by reference to our Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”), and our Second Amended and Restated Bylaws (the “Bylaws”), both of which are exhibits to our Annual Reports on Form 10-K.

Our authorized capital stock consists of 200,000,000 shares of Class A Common Stock, 35,000,000 shares of Class B common stock, par value $0.001 per share (“Class B Common Stock”), and 10,000,000 shares of blank check preferred stock.

Voting Rights

Holders of our Class A Common Stock and our Class B Common Stock are each entitled to cast one vote per share. Holders of our Class A Common Stock are not entitled to cumulate their votes in the election of directors. Holders of Class A Common Stock and Class B Common Stock generally vote together as a single class on all matters presented to the stockholders for their vote or approval. Generally, all matters to be voted on by stockholders must be approved by a majority (or, in the case of election of directors, by a plurality) of the votes entitled to be cast by all stockholders present in person or represented by proxy, voting together as a single class. Except as otherwise provided by law, amendments to the amended and restated certificate of incorporation must be approved by a majority or, in some cases, a super-majority of the combined voting power of all shares entitled to vote, voting together as a single class.

Dividend Rights

Holders of Class A Common Stock ratably (based on the number of shares of Class A Common Stock held) if and when any dividend is declared by the board of directors out of funds legal available therefor, subject to any statutory or contractual restrictions on the payment of dividends and to any restrictions on the payment of dividends imposed by the terms of any outstanding preferred stock.

Liquidation Rights

On the liquidation, dissolution or winding up of Shake Shack Inc., each holder of Class A Common Stock will be entitled to a pro rata distribution of any assets available for distribution to common stockholders.

Other Matters

Shares of Class A Common Stock are not subject to redemption and do not have preemptive rights to purchase additional shares of Class A Common Stock. Holders of shares of our Class A Common Stock do not have subscription, redemption or conversion rights. There are no redemption or sinking fund provisions applicable to the Class A Common Stock.

Exclusive Venue

Our amended and restated certificate of incorporation requires, to the fullest extent permitted by law, that (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action asserting a claim against us arising pursuant to any provision of the General Corporation Law of the State of Delaware ("DGCL") or our amended and restated certificate of incorporation or the bylaws or (iv) any action asserting a claim against us governed by the internal affairs doctrine will have to be brought only in the Court of Chancery in the State of Delaware. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Classified Board of Directors

Our amended and restated certificate of incorporation provides that our board of directors is divided into three classes, with the classes as nearly equal in number as possible and each class serving three-year staggered terms. Pursuant to the terms of the Stockholders Agreement (as defined in our Bylaws), directors designated by certain parties to the Stockholders Agreement may only be removed with or without cause by the request of the party entitled to designate such director. In all other cases and at any other time, directors may only be removed from our board of directors for cause by the affirmative vote of at least a majority of the confirmed voting power of our Class A Common Stock and Class B Common Stock. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control of us or our management.

Authorized but Unissued Shares

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 NYSE. 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.

Requirements for Advance Notification of Stockholder Meetings, Nominations and Proposals

Our amended and restated certificate of incorporation provides that stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of our board of directors or by a qualified stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered timely written notice in proper form to our secretary of the stockholder’s intention to bring such business before the meeting. Our amended and restated certificate of incorporation provides that, subject to applicable law, special meetings of the stockholders may be called only by a resolution adopted by the affirmative vote of the majority of the directors then in office. Our bylaws prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting. In addition, any stockholder who wishes to bring business before an annual meeting or nominate directors must comply with the advance notice and duration of ownership requirements set forth in our bylaws and provide us with certain information. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers or changes in control of us or our management.

Stockholder Action by Written Consent

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 amended and restated certificate of incorporation provides otherwise. Our amended and restated certificate of incorporation provides that stockholder action by written consent is permitted only if the action to be effected by such written consent and the taking of such action by such written consent have been previously approved by the board of directors.

Amendment of Amended and Restated Certificate of Incorporation or Bylaws

The DGCL provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation or bylaws, unless a corporation’s certificate of incorporation or bylaws, as the case may be, requires a greater percentage. Our bylaws may be amended or repealed by a majority vote of our board of directors or by the affirmative vote of the holders of at least 66-2⁄3% of the votes which all our stockholders would be entitled to cast in any annual election of directors. In addition, the affirmative vote of the holders of at least 66-2⁄3% of the votes which all our stockholders would be entitled to cast in any election of directors is required to amend or repeal or to adopt any provisions inconsistent with any of the provisions of our certificate described above.
