Appraisal Rights

Mr. Dorsey will hold following the merger. Any such agreements with existing holders of our common stock (including Mr. Dorsey) will not increase or decrease the per share price paid to our stockholders in the merger. Twitter has been advised by Mr. Dorsey and representatives of Mr. Musk that there is no agreement, arrangement, or understanding, whether express or implied, between Mr. Dorsey, on the one hand, and Parent or its affiliates (including Mr. Musk), on the other hand, relating to the voting or contribution of shares of our common stock held by Mr. Dorsey in connection with the merger and, as of the date of this proxy statement, Twitter has not received any information to the contrary.

Pursuant to the merger agreement, Mr. Musk has agreed to vote all of his shares of our common stock in favor of the adoption of the merger agreement. As of June 30, 2022, Mr. Musk beneficially holds approximately 9.5 percent of our common stock. For additional information regarding beneficial ownership of common stock, see the section of this proxy statement captioned “Security Ownership of Certain Beneficial Owners and Management.”

Following the merger, it is expected that Mr. Musk will be a substantial stockholder of Twitter with substantial control over Twitter’s business and operations. In that capacity, Mr. Musk may be able to cause Twitter to enter into various agreements or arrangements with him, including to compensate him for service on the Twitter Board or as an executive of Twitter. As of the date of this proxy statement, Twitter has no knowledge that Mr. Musk will ultimately pursue such agreements or arrangements.

No Arrangements with Morgan Stanley

One or more affiliates of Morgan Stanley beneficially hold approximately 8.7% of our common stock. (For additional information regarding beneficial ownership of common stock, see the section of this proxy statement captioned “Security Ownership of Certain Beneficial Owners and Management.”) Morgan Stanley and certain of its affiliates are providing financial advisory services to Mr. Musk, Parent and Acquisition Sub. In addition, affiliates of Morgan Stanley are parties to the bank debt financing.

Twitter has been advised by representatives of each of Mr. Musk and Morgan Stanley that there were no agreements, arrangements or understandings regarding the voting of our common stock held by Morgan Stanley or any of its affiliates in connection with the merger and, as of the date of this proxy statement, Twitter has not received any information to the contrary.

Closing and Effective Time of the Merger

The closing of the merger will take place as soon as possible in accordance with the terms of the merger agreement, but no later than the second business day after the satisfaction or waiver of all of the conditions to closing of the merger, other than conditions that by their terms are to be satisfied at the closing of the merger, but subject to the satisfaction or waiver of such conditions at the closing, unless another time, date or place is agreed to in writing by the parties. On the closing date of the merger, the parties will file a certificate of merger with the Secretary of State of the State of Delaware as provided under the DGCL. The merger will become effective on the date and time at which the certificate of merger has been duly filed with the Secretary of State of the State of Delaware or such other date and time as may be agreed to by Twitter and Parent and set forth in such certificate of merger in accordance with the DGCL.

Appraisal Rights

If the merger is consummated, our stockholders who (1) do not vote in favor of the adoption of the merger agreement (whether by voting against the adoption of the merger agreement, abstaining or otherwise not voting with respect to the adoption of the merger agreement), (2) properly demand an appraisal of their applicable shares of our common stock prior to the vote on the adoption of the

merger agreement, (3) continuously hold their applicable shares through the effective time of the merger, (4) otherwise comply with the procedures of Section 262 of the DGCL (which we refer to as “Section 262”), including by satisfying certain ownership thresholds set forth therein, and (5) do not withdraw their demands or otherwise lose their rights to appraisal may, subject to the conditions of Section 262, seek appraisal of their shares in connection with the merger under Section 262. Unless the context requires otherwise, all references in Section 262 and in this summary to a “stockholder” or to a “holder of shares” are to a record holder of our common stock.

The following discussion is not a complete statement of the law pertaining to appraisal rights under the DGCL and is qualified in its entirety by the full text of Section 262, which is attached to this proxy statement as Annex B and incorporated into this proxy statement by reference. The following summary does not constitute any legal or other advice and does not constitute a recommendation that our stockholders exercise their appraisal rights under Section 262. Only a holder of record of shares of our common stock is entitled to demand appraisal of the shares registered in that holder’s name. A person having a beneficial interest in shares of our common stock held of record in the name of another person, such as a bank, broker or other nominee, must act promptly to cause the record holder to demand an appraisal of such holder’s shares. If you hold your shares of our common stock through a bank, broker or other nominee and you wish to exercise appraisal rights, you should consult with your bank, broker or the other nominee to ensure that appraisal rights are exercised. Stockholders should carefully review the full text of Section 262 as well as the information discussed below.

Under Section 262, if the merger is completed, holders of record of shares of our common stock who (1) submit a written demand for appraisal of such stockholder’s shares to Twitter prior to the vote on the adoption of the merger agreement; (2) do not vote in favor of the adoption of the merger agreement (whether by voting against the adoption of the merger agreement, abstaining or otherwise not voting with respect to the adoption of the merger agreement); and (3) continuously are the record holders of such shares through the effective time of the merger may be entitled to have their shares of our common stock appraised by the Delaware Court of Chancery and to receive payment in cash of the “fair value” of the shares of our common stock, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with (unless the Delaware Court of Chancery in its discretion determines otherwise for good cause shown) interest on the amount determined by the Delaware Court of Chancery to be fair value from the effective date of the merger through the date of payment of the judgment. However, after an appraisal petition has been filed, the Delaware Court of Chancery, at a hearing to determine stockholders entitled to appraisal rights, will dismiss appraisal proceedings as to all of our stockholders who asserted appraisal rights unless (1) the total number of shares of our common stock entitled to appraisal exceeds one percent of the outstanding shares of our common stock as measured in accordance with subsection (g) of Section 262; or (2) the value of the merger consideration in respect of such shares exceeds $1 million. We refer to these conditions as the “ownership thresholds.” Unless the Delaware Court of Chancery, in its discretion, determines otherwise for good cause shown, interest on an appraisal award will accrue and compound quarterly from the effective time of the merger through the date the judgment is paid at five percent over the Federal Reserve discount rate (including any surcharge) as established from time to time during such period (except that, if at any time before the entry of judgment in the proceeding, the surviving corporation makes a voluntary cash payment to each stockholder entitled to appraisal, interest will accrue thereafter only upon the sum of (1) the difference, if any, between the amount so paid and the fair value of the shares as determined by the Delaware Court of Chancery; and (2) interest theretofore accrued, unless paid at that time). The surviving corporation is under no obligation to make such voluntary cash payment prior to such entry of judgment.

Under Section 262, where a merger agreement is to be submitted for adoption at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, must notify each of its

stockholders of record as of the record date for notice of such meeting that appraisal rights are available and include in the notice a copy of Section 262. This proxy statement constitutes Twitter’s notice to our stockholders that appraisal rights are available in connection with the merger, and the full text of Section 262 is attached to this proxy statement as Annex B. In connection with the merger, any holder of shares of our common stock who wishes to exercise appraisal rights, or who wishes to preserve such holder’s right to do so, should review Annex B carefully. Failure to strictly comply with the requirements of Section 262 in a timely and proper manner may result in the loss of appraisal rights under the DGCL. A stockholder who loses his, her or its appraisal rights will be entitled to receive the per share price described in the merger agreement without interest and less any applicable withholding taxes. Because of the complexity of the procedures for exercising the right to seek appraisal of shares of our common stock, Twitter believes that if a stockholder is considering exercising such rights, that stockholder should seek the advice of legal counsel.

Stockholders wishing to exercise the right to seek an appraisal of their shares of our common stock must do ALL of the following:

•

the stockholder must not vote in favor of the proposal to adopt the merger agreement;

•

the stockholder must deliver to Twitter a written demand for appraisal before the vote on the merger agreement at the special meeting; and

•

the stockholder must continuously hold the shares from the date of making the demand through the effective time of the merger (a stockholder will lose appraisal rights if the stockholder transfers the shares before the effective time of the merger).

In addition, after an appraisal petition has been filed, the Delaware Court of Chancery, at a hearing to determine stockholders entitled to appraisal rights, will dismiss appraisal proceedings as to all of our stockholders who asserted appraisal rights unless one of the ownership thresholds is met.

Because a proxy that does not contain voting instructions will, unless revoked, be voted in favor of the adoption of the merger agreement, each of our stockholders who votes by proxy and who wishes to exercise appraisal rights must vote against the adoption of the merger agreement or abstain with respect to such proposal.

Filing Written Demand

A stockholder wishing to exercise appraisal rights must deliver to Twitter, before the vote on the adoption of the merger agreement at the special meeting, a written demand for the appraisal of such stockholder’s shares. In addition, that stockholder must not vote or submit a proxy in favor of the adoption of the merger agreement. A vote in favor of the adoption of the merger agreement, in person at the special meeting or by proxy (whether by mail or via the internet or telephone), will constitute a waiver of appraisal rights in respect of the shares so voted and will nullify any previously filed written demands for appraisal. A stockholder exercising appraisal rights must hold of record the shares on the date the written demand for appraisal is made and must continue to hold the shares of record through the effective time of the merger. Neither voting (in person or by proxy) against the adoption of the merger agreement nor abstaining from voting or failing to vote on the proposal to adopt the merger agreement will, in and of itself, constitute a written demand for appraisal satisfying the requirements of Section 262. The written demand for appraisal must be in addition to and separate from any proxy or vote on the adoption of the merger agreement.

Only a holder of record of shares of our common stock is entitled to demand appraisal rights for the shares registered in that holder’s name. A demand for appraisal in respect of shares of our common

stock should be executed by or on behalf of the holder of record and must reasonably inform Twitter of the identity of the holder and that the stockholder intends thereby to demand an appraisal of such stockholder’s shares. If the shares are owned of record in the name of another person, such as a broker, fiduciary, depositary or other nominee, such demand must be executed by or on behalf of the record owner, and if such shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent, including an authorized agent for two or more joint owners, may execute a demand for appraisal on behalf of a holder of record; however, the agent must identify the record owner or owners and expressly disclose that, in executing the demand, the agent is acting as agent for the record owner or owners. If a stockholder holds shares of our common stock through a broker who in turn holds the shares through a central securities depository nominee such as Cede & Co., a demand for appraisal of such shares must be made by or on behalf of the depository nominee and must identify the depository nominee as record holder.

STOCKHOLDERS WHO HOLD THEIR SHARES IN “STREET NAME” BY A BANK, BROKER, TRUST OR OTHER NOMINEE AND WHO WISH TO EXERCISE APPRAISAL RIGHTS SHOULD CONSULT WITH THEIR BANK, BROKER, TRUST OR OTHER NOMINEE, AS APPLICABLE, TO DETERMINE THE APPROPRIATE PROCEDURES FOR THE BANK, BROKER, TRUST OR OTHER NOMINEE TO MAKE A DEMAND FOR APPRAISAL OF THOSE SHARES. A PERSON HAVING A BENEFICIAL INTEREST IN SHARES HELD OF RECORD IN THE NAME OF ANOTHER PERSON, SUCH AS A BANK, BROKER, TRUST OR OTHER NOMINEE, MUST ACT PROMPTLY TO CAUSE THE RECORD HOLDER TO FOLLOW PROPERLY AND IN A TIMELY MANNER THE STEPS NECESSARY TO PERFECT APPRAISAL RIGHTS.

All written demands for appraisal pursuant to Section 262 should be mailed or delivered to:

Twitter, Inc.

1355 Market Street, Suite 900

San Francisco, California 94103

Attention: Corporate Secretary

At any time within 60 days after the effective date of the merger, any holder of shares of our common stock who has not commenced an appraisal proceeding or joined that proceeding as a named party may withdraw his, her or its demand for appraisal and accept the per share price offered pursuant to the merger agreement, without interest and less any applicable withholding taxes, by delivering to Twitter, as the surviving corporation, a written withdrawal of the demand for appraisal. However, any such attempt to withdraw the demand made more than 60 days after the effective time of the merger will require written approval of the surviving corporation. Notwithstanding the foregoing, no appraisal proceeding in the Delaware Court of Chancery will be dismissed as to any stockholder without the approval of the Delaware Court of Chancery, and such approval may be conditioned upon such terms as the Delaware Court of Chancery deems just; provided, however, that this will not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the merger consideration within 60 days after the effective time of the merger. If Twitter, as the surviving corporation, does not approve a request to withdraw a demand for appraisal when that approval is required, or, except with respect to any stockholder who withdraws such stockholder’s demand in accordance with the proviso in the immediately preceding sentence, if the Delaware Court of Chancery does not approve the dismissal of an appraisal proceeding with respect to a stockholder, the stockholder will be entitled to receive only the appraised value determined in any such appraisal proceeding, which value could be less than, equal to or more than the per share price being offered pursuant to the merger agreement.

Notice by the Surviving Corporation

If the merger is completed, within 10 days after the effective time of the merger, the surviving corporation will notify each record holder of shares of our common stock who has properly made a written demand for appraisal pursuant to Section 262, and who has not voted in favor of the adoption of the merger agreement, that the merger has become effective and the effective date thereof.

Filing a Petition for Appraisal

Within 120 days after the effective time of the merger, but not thereafter, the surviving corporation or any holder of shares of our common stock who has complied with Section 262 and is entitled to appraisal rights under Section 262 (or a beneficial owner in the circumstances described in the next paragraph) may commence an appraisal proceeding by filing a petition in the Delaware Court of Chancery, with a copy served on the surviving corporation in the case of a petition filed by a stockholder, demanding a determination of the fair value of the shares held by all dissenting stockholders entitled to appraisal. The surviving corporation is under no obligation, and has no present intention, to file a petition, and stockholders should not assume that the surviving corporation will file a petition or initiate any negotiations with respect to the fair value of the shares of our common stock. Accordingly, any holders of shares of our common stock who desire to have their shares appraised should initiate all necessary action to perfect their appraisal rights in respect of their shares of our common stock within the time and in the manner prescribed in Section 262. If no petition for appraisal is filed with the Delaware Court of Chancery within 120 days after the effective time of the merger, stockholders’ rights to appraisal shall cease, and all holders of shares of our common stock will be entitled to receive the consideration offered pursuant to the merger agreement, without interest.

Within 120 days after the effective time of the merger, any holder of shares of our common stock who has complied with the requirements for an appraisal of such holder’s shares pursuant to Section 262 will be entitled, upon written request, to receive from the surviving corporation a statement setting forth the aggregate number of shares not voted in favor of the adoption of the merger agreement and with respect to which Twitter has received demands for appraisal, and the aggregate number of holders of such shares. The surviving corporation must send this statement to the requesting stockholder within 10 days after receipt by the surviving corporation of the written request for such a statement or within 10 days after the expiration of the period for delivery of demands for appraisal, whichever is later. A beneficial owner of shares of our common stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition seeking appraisal or request from the surviving corporation the foregoing statements. As noted above, however, the demand for appraisal can only be made by a stockholder of record.

If a petition for an appraisal is duly filed by a holder of shares of our common stock and a copy thereof is served upon the surviving corporation, the surviving corporation will then be obligated within 20 days after such service to file with the Delaware Register in Chancery a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached. The Delaware Court of Chancery may order that notice of the time and place fixed for the hearing of such petition be given to the surviving corporation and all of the stockholders shown on the verified list at the addresses stated therein. Any such notice shall also be given by one or more publications at least one week before the day of the hearing in a newspaper of general circulation published in the City of Wilmington, Delaware or any other publication which the Delaware Court of Chancery deems advisable. The costs of any such notice are borne by the surviving corporation.

After notice to dissenting stockholders as required by the court, at the hearing on such petition, the Delaware Court of Chancery will determine the stockholders who have complied with Section 262 and

who have become entitled to appraisal rights thereunder. The Delaware Court of Chancery may require the stockholders who demanded appraisal for their shares to submit their stock certificates to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings. If any stockholder fails to comply with the direction, the Delaware Court of Chancery may dismiss the proceedings as to such stockholder.

Pursuant to Section 262(g) of the DGCL, the Delaware Court of Chancery will dismiss appraisal proceedings as to all of our stockholders who assert appraisal rights unless (1) the total number of shares entitled to appraisal exceeds one percent of the outstanding shares of our common stock as measured in accordance with Section 262(g) of the DGCL; or (2) the value of the merger consideration in respect of such shares exceeds $1 million.

Determination of Fair Value

Where proceedings are not dismissed, the appraisal proceeding will be conducted in accordance with the rules of the Delaware Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding, the Delaware Court of Chancery will determine the “fair value” of the shares of our common stock, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining fair value, the Delaware Court of Chancery will take into account all relevant factors. Unless the Delaware Court of Chancery in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment will be compounded quarterly and will accrue at five percent over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. However, the surviving corporation has the right, at any time prior to the Delaware Court of Chancery’s entry of judgment in the proceedings, to make a voluntary cash payment to each stockholder seeking appraisal. If the surviving corporation makes a voluntary cash payment pursuant to subsection (h) of Section 262, interest will accrue thereafter only on the sum of (1) the difference, if any, between the amount paid by the surviving corporation in such voluntary cash payment and the fair value of the shares as determined by the Delaware Court of Chancery; and (2) interest accrued before such voluntary cash payment, unless paid at that time. In Weinberger v. UOP, Inc., the Supreme Court of Delaware discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that “proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court” should be considered, and that “[f]air price obviously requires consideration of all relevant factors involving the value of a company.” The Delaware Supreme Court stated that, in making this determination of fair value, the court must consider market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts that could be ascertained as of the date of the merger that throw any light on future prospects of the merged corporation. Section 262 provides that fair value is to be “exclusive of any element of value arising from the accomplishment or expectation of the merger.” In Cede & Co. v. Technicolor, Inc., the Delaware Supreme Court stated that such exclusion is a “narrow exclusion [that] does not encompass known elements of value,” but which rather applies only to the speculative elements of value arising from such accomplishment or expectation. In Weinberger, the Supreme Court of Delaware also stated that “elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered.”

Stockholders considering seeking appraisal should be aware that the fair value of their shares as so determined by the Delaware Court of Chancery could be more than, the same as or less than the consideration they would receive pursuant to the merger if they did not seek appraisal of their shares and that an opinion of an investment banking firm as to the fairness from a financial point of view of the
