Item 1.01.

Entry into a Material Definitive Agreement.

On August 28, 2025, Global Business Travel Group, Inc. a Delaware corporation (the “Company”), entered into Amendment No. 5 to Agreement and Plan of Merger (“Amendment No. 5 to the Merger Agreement”) with CWT Holdings, LLC, a Delaware limited liability company (“CWT”), Cape Merger Sub I LLC, a Delaware limited liability company (“Merger Sub I”), Cape Merger Sub II LLC, a Delaware limited liability company (“Merger Sub II” and together with Merger Sub I, the “Merger Subs”) and Redwood Drawdown Partners III, LLC, solely in its capacity as the representative of the equityholders of CWT (the “Member Representative” and together with the Company, CWT and the Merger Subs, the “Parties”).

As previously announced, on March 24, 2024, the Parties entered into an Agreement and Plan of Merger (as amended on January 17, 2025, March 17, 2025, March 20, 2025 and March 21, 2025, and as further amended, the “Merger Agreement”), pursuant to which, among other things, (i) Merger Sub I will merge with and into CWT (the “First Merger”) with CWT surviving the First Merger as an indirect subsidiary of the Company (the “First Merger Surviving Company”) and (ii) the First Merger Surviving Company will merge with and into Merger Sub II (the “Second Merger” and, together with the First Merger, the “Mergers”) with Merger Sub II surviving the Second Merger as an indirect subsidiary of the Company. Capitalized terms used and not otherwise defined herein shall have the respective meanings ascribed to them in the Merger Agreement.

Pursuant to Amendment No. 5 to the Merger Agreement, the Parties (i) agreed that the Company would hold back 400,000 shares (the “Holdback Shares”) of Class A common stock, par value $0.0001 per share (“Common Stock”) that would otherwise be released to CWT’s equityholders at the closing of the Mergers (the “Closing”) and (ii) increased the amount of Debt-Like Items by $13,660,000, thereby reducing the Estimated Purchase Price and Final Purchase Price by an equal amount. On the date that is nine (9) months following the Closing Date, the Company will release to CWT’s equityholders the aggregate number of Holdback Shares, minus a number of Holdback Shares equal to fifty percent (50%) of the aggregate cash amount of certain resolved claims arising out of the Business Restructuring, divided by $7.50; provided that if any such claims are pending on such date, the applicable portion of the Holdback Shares as the Company deems reasonably necessary to satisfy such pending claims shall be retained by the Company and shall not be released until such pending claims are finally resolved. In addition, the Company agreed to pay to CWT’s equityholders an amount in cash equal to the amount by which $20,000,000 exceeds fifty percent (50%) of certain costs arising out of the Business Restructuring promptly following the last date with respect to which such costs are payable or reimbursable by the Company or any of its subsidiaries to the counterparty of the Business Restructuring.

From and after the date of Amendment No. 5 to the Merger Agreement, references in the Merger Agreement to this “Agreement” or any provision thereof shall be deemed to refer to the Merger Agreement or such provision as amended by Amendment No. 5 to the Merger Agreement unless the context otherwise requires.

Except as otherwise expressly provided in Amendment No. 5 to the Merger Agreement, Amendment No. 5 to the Merger Agreement does not by implication or otherwise limit, impair, constitute a waiver of, or otherwise affect the rights and remedies of the Parties under the Merger Agreement and do not in any way alter, modify, amend or affect any of the terms, conditions, obligations, covenants or agreements contained in the Merger Agreement, all of which remain unchanged and continue in full force and effect.

Registration Rights Agreement; Lock-Up

At the Closing, the Company entered into a registration rights agreement (the “Registration Rights Agreement”) pursuant to which, among other things, the Company agreed to register for resale, pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), shares of Common Stock that were issued to certain of CWT’s equityholders in connection with the Mergers and who duly execute and deliver a signature page to the Registration Rights Agreement. The Merger Agreement provides that (a) until the date that is ninety (90) days following the date of Closing (the “Closing Date”), no Member shall, subject to certain exceptions, directly or indirectly, transfer any shares of Common Stock issued to such Member pursuant to the Merger Agreement and (b) from and after the date that is ninety-one (91) days following the Closing Date until the date that is two hundred and seventy (270) days following the Closing Date, no Member shall transfer more than fifty percent (50%) of the shares of Common Stock issued to such Member pursuant to the Merger Agreement.

The foregoing descriptions of the Merger Agreement, Amendment No. 5 to the Merger Agreement, the Registration Rights Agreement and the transactions contemplated thereby do not purport to be complete, and are subject to, and qualified in their entirety by reference to, the full text of (i) Amendment No. 5 to the Merger Agreement attached as Exhibit 2.1 and incorporated by reference herein, (ii) the Registration Rights Agreement, which is attached as Exhibit 2.2 and is incorporated by reference herein, (iii) the Merger Agreement prior to any amendments thereto, which was previously filed as Exhibit 2.1 to the Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission (the “SEC”) by the Company on March 25, 2024, (iv) Amendment No. 1 to the Merger Agreement, which was previously filed as Exhibit 2.1 to the Current Report on Form 8-K filed with the SEC by the Company on January 17, 2025, and (v) Amendment Nos. 2, 3 and 4 to the Merger Agreement, which were previously filed as Exhibits 2.1, 2.2 and 2.3 to the Current Report on Form 8-K filed with the SEC by the Company on March 17, 2025. Amendment No. 5 to the Merger Agreement and the Registration Rights Agreements have been included to provide investors with information regarding their terms and are not intended to provide any other factual information about the Company, Merger Subs, CWT, the Member Representative or their respective subsidiaries or affiliates. Further, Amendment No. 5 to the Merger Agreement should not be read alone but should be read in conjunction with the Merger Agreement, which it amends, and with the other information regarding the Merger Agreement, the Mergers, the Parties, their respective affiliates and their respective businesses that is contained in, or incorporated by reference into, the Company’s other SEC filings.

There can be no assurance that future developments affecting us, including as a result of the transaction, will be those that we have anticipated.
