&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (e)

This Agreement and all actions, proceedings, causes of action, claims or counterclaims (whether based on contract, tort, statute or otherwise) based upon, arising out of or relating to this Agreement or the actions of the Parties in the negotiation, administration, performance and enforcement thereof (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in connection with this Agreement or as an inducement to enter into this Agreement), shall be governed by, and construed in accordance with the Laws of the State of Delaware, including its statutes of limitations, without giving effect to any choice or conflict of Laws provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws, including any statutes of limitations, of any jurisdiction other than the State of Delaware. Each of the Parties (a) irrevocably consents to the service of the summons and complaint and any other process (whether inside or outside the territorial jurisdiction of the Chosen Courts) in any Legal Proceeding in connection with, arising out of or otherwise relating to this Agreement, any instrument or other document delivered pursuant to this Agreement, for and on behalf of itself or any of its properties or assets, in accordance with Section 13(a) or in such other manner as may be permitted by applicable Law, and nothing in this Section 13(e) will affect the right of any Party to serve legal process in any other manner permitted by applicable Law; (b) irrevocably and unconditionally consents and submits itself and its properties and assets in any Legal Proceeding to the exclusive general jurisdiction of the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware (or, if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any other state or federal court within the State of Delaware) (the "**Chosen Courts**") in the event that any dispute or controversy arises in connection with this Agreement, any instrument or other document delivered pursuant to this Agreement or the transactions contemplated hereby or thereby; (c) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court; (d) agrees that any Legal Proceeding arising in connection with this Agreement, any instrument or other document delivered pursuant to this Agreement or the transactions contemplated hereby or thereby shall be brought, tried and determined only in the Chosen Courts; (e) waives any objection that it may now or hereafter have to the venue of any such Legal Proceeding in the Chosen Courts or that such Legal Proceeding was brought in an inconvenient court and agrees not to plead or claim the same; and (f) agrees that it shall not bring any Legal Proceeding relating to this Agreement, any instrument or other document delivered pursuant to this Agreement or the transactions contemplated hereby or thereby in any court other than the Chosen Courts. Each of the Parties agrees that a final judgment in any Legal Proceeding in the Chosen Courts will be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (f)

<u>Waiver of Jury Trial</u>. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE PURSUANT TO THIS AGREEMENT, any instrument or other document delivered pursuant to this Agreement or the transactions contemplated hereby IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF any LEGAL Proceeding (WHETHER FOR BREACH OF CONTRACT, TORTIOUS CONDUCT or OTHERWISE) directly or indirectly arising out of or relating to this Agreement, any instrument or other document delivered pursuant to this Agreement or the transactions contemplated hereby.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (g)

<u>Assignment</u>. Other than in connection with any Transfer permitted by <u>Section 4</u>, no Party may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other Parties hereto, except that Parent and Merger Sub will have the right to assign all or any portion of their respective rights and obligations pursuant to this Agreement to any Affiliate thereof to whom they have assigned the Merger Agreement; <u>provided</u>, <u>however</u>, that, following the Effective Time, Parent and Merger Sub may assign, in their sole discretion and without the consent of any other party, any or all of their rights, interests and obligations hereunder to each other or to one or more direct or indirect wholly-owned Subsidiaries of Parent in connection with the assignment of the rights, interests and obligations of Parent and/or Merger Sub under the Merger Agreement to such direct or indirect wholly-owned Subsidiaries of Parent in accordance with the terms of the Merger Agreement; <u>provided</u>, <u>further</u>, that no such assignment shall relieve Parent or Merger Sub of any of their respective obligations under this Agreement. Any assignment in violation of the preceding sentence shall be void *ab initio*. Subject to the preceding two sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective successors and assigns.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (h)

<u>Severability of Provisions</u>. The provisions of this Agreement shall be deemed severable and the illegality, invalidity or unenforceability of any provision shall not affect the legality, validity or enforceability of the other provisions of this Agreement. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is held by a court of competent jurisdiction or other Governmental Authority as illegal, invalid or unenforceable, (i) a suitable and equitable provision to be negotiated by the Parties hereto, each acting reasonably and in good faith, shall be substituted therefor in order to carry out, so far as may be legal, valid and enforceable, the original intent and purpose of such illegal, invalid or unenforceable provision, and (ii) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such illegality, invalidity or unenforceability, nor shall such illegality, invalidity or unenforceability affect the legality, validity or enforceability of such provision, or the application of such provision, in any other jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i)

<u>Specific Performance</u>. Each of the Parties hereto acknowledges and agrees that the rights of each Party hereto to consummate the transactions contemplated hereby are special, unique and of extraordinary character and that if for any reason any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached, immediate and irreparable harm or damage would be caused for which money damages would not be an adequate remedy. Accordingly, each Party hereto agrees that, in addition to any other available remedies a Party may have in equity or at law, each Party hereto shall be entitled to enforce specifically the terms and provisions of this Agreement and to an injunction restraining any breach or violation or threatened breach or violation of the provisions of this Agreement in the Chosen Courts without necessity of posting a bond or other form of security. In the event that any Legal Proceeding should be brought in equity to enforce the provisions of this Agreement, no Party shall allege, and each Party hereto hereby waives the defense, that there is an adequate remedy at Law.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (j)

<u>Amendment</u>.

Notwithstanding anything herein to the contrary, this Agreement may not be amended, waived or modified in any manner without the prior written consent of the Company and the approval of the Special Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (k)

<u>No Presumption</u>. This Agreement shall be construed as if drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provisions of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (l)

<u>No Agreement Until Executed</u>. This Agreement shall not be effective unless and until (i) the Merger Agreement is executed by all parties thereto and (ii) this Agreement is executed by the Parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (m)

<u>No Ownership Interest</u>. Nothing contained in this Agreement shall be deemed to vest in Parent or Merger Sub any direct or indirect ownership or incidence of ownership of or with respect to the Stockholder Securities.

Class A Common Stock, par value $0.0001 per share

**(b) Name of Issuer:**
Global Business Travel Group, Inc.

**(c) Address of Issuer's Principal Executive Offices:**

This Amendment No. 1 to the Schedule 13D (the "Amendment No. 1") amends and supplements the Schedule 13D filed by the Reporting Person with the SEC on October 2, 2025 (the "Schedule 13D"). Except as amended and supplemented by the Amendment No. 1, the Schedule 13D remains unchanged.

This Amendment No.1 is being filed to reflect the entry into a Voting and Support Agreement dated May 3, 2026 (the "Voting and Support Agreement") by QIA Retail Holding LLC ("QIA Retail"), a wholly-owned subsidiary of the Reporting Person, with the Issuer, Gaia Purchaser, Inc., a Delaware corporation ("Parent"), and Gaia Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent ("Merger Sub"), with respect to the shares of Class A Common Stock held of record by QIA Retail.

**Item 4. Purpose of Transaction**

Item 4 of the Schedule 13D is hereby supplemented and amended to add the following information:

Merger Agreement

On May 2, 2026, Issuer entered into an Agreement and Plan of Merger (the "Merger Agreement") with Parent and Merger Sub, pursuant to which the Issuer is to be acquired by Long Lake Management Holdings, Inc. Pursuant to the Merger Agreement, Merger Sub will be merged with and into the Issuer (the "Merger" and, together with the other transactions contemplated by the Merger Agreement, the "Transactions"), with the Issuer surviving as a wholly owned subsidiary of Parent. Upon the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the "Effective Time"), each share of Class A Common Stock that is issued and outstanding as of immediately prior to the Effective Time (other than any shares of Class A Common Stock held by the Issuer as treasury stock, owned by Parent or any of its subsidiaries (including Merger Sub), unvested pursuant to a side letter with the Issuer, pursuant to which appraisal rights have been properly exercised and perfected (and not withdrawn or lost) in accordance with Section 262 of the DGCL, and, if applicable, any shares of Class A Common Stock held by any direct or indirect wholly owned subsidiary of Parent (other than Merger Sub) or of the Issuer that are converted in the manner set forth in the Merger Agreement) will be automatically cancelled, extinguished and converted into the right to receive cash in an amount equal to $9.50, without interest thereon (the "Per Share Price"), as more fully described in the Form 8-K filed by the Issuer with the SEC on May 4, 2026. Neither the Reporting Person nor QIA Retail is party to the Merger Agreement.

Voting and Support Agreement

In connection with the execution of the Merger Agreement, QIA Retail, the Issuer, Parent and Merger Sub have entered into the Voting and Support Agreement. On the terms and subject to the conditions set forth in the Voting and Support Agreement, QIA Retail has agreed to vote all shares of Class A Common Stock over which it has voting power (representing, in the aggregate approximately, 16.7% of the Issuer's total outstanding voting power as of May 3, 2026) (A) in favor of (i) the adoption of the Merger Agreement, approval of the Merger and related transactions, (ii) any adjournment or postponement requested by the Issuer or Parent, (iii) any amendment to the Merger Agreement that is not an adverse amendment (i.e., one that decreases the per share price, changes its form, or is materially adverse to QIA Retail), and (iv) any other proposal necessary or desirable to consummate the Merger, and (B) against (i) any competing acquisition proposal, (ii) any action likely to cause a breach of the Merger Agreement or the Voting and Support Agreement, (iii) any action that could prevent closing conditions of the Merger from being satisfied, and (iv) any action that could delay or impede the Merger. However, if the board of directors of the Issuer changes its recommendation for the Merger due to an intervening event, QIA Retail is only required to vote a pro rata portion of its shares equal to 35% of the Issuer's total outstanding voting power (calculated proportionally among all stockholders who signed voting and support agreements with the Issuer, Parent and Merger sub).

Prior to the termination date of the Voting and Support Agreement, QIA Retail may not transfer or otherwise dispose of any shares of Class A Common Stock, enter into any related contract or arrangement, grant proxies, deposit shares into a voting trust, or take any other action that would impede the consummation of the Merger, with the exception of certain permitted transfers to controlled affiliates, provided the transferee executes a joinder agreement binding them to the terms of the Voting and Support Agreement. The Voting and Support Agreement also restricts QIA Retail and its controlled affiliates from taking any action that the Issuer or its subsidiaries would be prohibited from taking under the non-solicitation provisions of the Merger Agreement, subject to certain exceptions.

The Voting and Support Agreement, and QIA Retail's obligations to vote in favor of the adoption of the Merger Agreement, will terminate automatically upon the earliest of (i) termination of the Merger Agreement in accordance with its terms, (ii) the effective time of the Merger, (iii) any amendment to the Merger Agreement that is adverse to QIA Retail in certain respects, as further set forth in the Voting and Support Agreement, (iv) written consent of the parties thereto, or (v) November 1, 2026 (or February 1, 2027, if the Merger Agreement's termination date is extended to such date).

The foregoing description of the Voting and Support Agreement and the transactions contemplated thereby does not purport to be complete and is subject to and qualified in its entirety by reference to the Voting and Support Agreement, a copy of which is filed as Exhibit 1 to this Amendment and is incorporated herein by reference.
