TABLE OF CONTENTS

THE COMPANY

GBTG operates American Express Global Business Travel, the world’s leading B2B travel platform, measured by 2021 TTV, according to Travel Weekly (“2022 Power List,” June 2022, Travel Weekly). We provide a full suite of differentiated, technology-enabled solutions to business travelers and business clients, suppliers of travel content (such as airlines, hotels, ground transportation and aggregators) and third-party travel agencies. We differentiate our value proposition through our commitment to deliver to our customers unrivaled choice, value and experience, with the powerful backing of American Express GBT.

We are at the center of the global B2B travel ecosystem, managing the end-to-end logistics of business travel and providing an important link between businesses, their employees, travel suppliers and other industry participants. We service our clients in the following ways:

•

Our portfolio of travel management solutions, built around and targeting the needs of key client segments we serve, provide extensive access to flights, hotel rooms, car rentals and other travel services as well as meeting and events solutions, including exclusive negotiated content, supported by a full suite of services that allows our clients to design and operate an efficient travel program and solve complex travel requirements across all stages of the business process from planning, booking, on trip, and post trip activities.

•

Our award-winning client facing proprietary platforms are built to deliver business value through optimized user experiences across the act of business travel. These platforms, accessible over web and mobile interfaces and powered by our data management infrastructure and built by one of the world’s largest product engineering teams dedicated to driving technical innovation across the business travel industry. These client facing platforms are known to the market as:

•

Egencia primarily focuses on digital-first clients (more than 90% of transactions were served through digital channels in 2022) who value a simple, easy to use and standardized end-to-end solution.

•

The GBT platform is a modular solution primarily focused on flexibility of service offerings; seamlessly integrating a wide range of third-party and proprietary software and services in to one complete travel solution designed and built around the needs of each customer.

•

GBT Partner Solutions extends our platform to our Network Partners, TMCs and independent advisors, by offering them access to our differentiated content and technology. Through GBT Partner Solutions, we aggregate business travel demand serviced by our Network Partners at low incremental cost, which we believe enhances the economics of our platform, generates increased return on investment and expands our geographic and segment footprint.

•

GBT Supply MarketPlace provides travel suppliers with efficient access to business travel clients serviced by our diverse portfolio of leading travel management solutions and Network Partners. We believe this access allows travel suppliers to benefit from premium demand (which we generally view as demand that is differentially valuable and profitable to suppliers) without incurring the costs associated with directly marketing to, and servicing the complex needs of, our business clients. Our travel supplier relationships generate efficiencies and cost savings that can be passed on to our business clients.

In June 2014, American Express established the joint venture (“JV”) comprising the GBT JerseyCo operations with a predecessor of Juweel held by a group of institutional investors led by an affiliate of Certares Management LLC. Since the formation of the JV in 2014, we have evolved from a leading TMC into a complete B2B travel platform, becoming one of the leading marketplaces in travel for business clients and travel suppliers according to Travel Weekly (“2022 Power List,” June 2022, Travel Weekly). Before June 2014, our operations were owned by American Express and primarily consisted of providing business travel solutions for business clients.

In May 2022, we executed long-term commercial agreements with American Express, including an amended and restated trademark license agreement (the “A&R Trademark License Agreement”), pursuant to which we continue to license the American Express trademarks used in the American Express Global Business Travel brand, and we license the American Express trademarks used in the American Express

The term of the A&R Trademark License Agreement is for 11 years from May 27, 2022, unless earlier terminated or extended.

On May 25, 2022, Apollo Strategic Growth Capital (“APSG”), a blank check company incorporated as a Cayman Islands exempted company, held an extraordinary general meeting of its shareholders at which the APSG shareholders considered and adopted, among other matters, a proposal to approve the Business Combination pursuant to the terms of the Business Combination Agreement. Upon the completion of the Business Combination and the other transactions contemplated by the Business Combination Agreement on May 27, 2022, GBT JerseyCo became a direct subsidiary of APSG, with APSG being re-domesticated as a Delaware corporation and renamed “Global Business Travel Group, Inc.” and conducting its business through GBT JerseyCo in an umbrella partnership-C corporation structure.

TABLE OF CONTENTS

DESCRIPTION OF CAPITAL STOCK

The following descriptions are summaries of the material terms of our Certificate of Incorporation and our Bylaws. Because they are only summaries, they do not contain all the information that may be important to you. For a complete description of the matters set forth in this section, you should refer to our Certificate of Incorporation and our Bylaws, the GBT JerseyCo Amended and Restated M&A, the Exchange Agreement and the Shareholders Agreement, which have been filed with the SEC and to the applicable provisions of Delaware law. Under “Description of Securities,” “we,” “us,” “our” and “Company” refer to GBTG and not to any of its subsidiaries.

General

Our purpose is to engage in any lawful act or activity for which a corporation may now or hereafter be organized under the Delaware General Corporation Law, as amended (the “DGCL”). Our authorized capital stock consists of (i) 3,000,000,000 shares of Class A Common Stock, par value $0.0001 per share, (ii) 3,000,000,000 shares of Class B common stock, par value $0.0001 per share (the “Class B Common Stock” and together with the Class A Common Stock, the “Common Stock”) and (iii) 6,010,000,000 shares of preferred stock, par value of $0.00001 per share (the “Preferred Stock”). With respect to our Preferred Stock, (a) 3,000,000,000 shares of Class A-1 preferred stock (the “Class A-1 Preferred Stock”) is designated pursuant to the Certificate of Designations for the Class A-1 Preferred Stock, (b) 3,000,000,000 shares of Class B-1 preferred stock (the “Class B-1 Preferred Stock”) is designated pursuant to the Certificate of Designations for the Class B-1 Preferred Stock and (c) the remaining 10,000,000 shares of preferred stock is undesignated Preferred Stock. Pursuant to our Certificate of Incorporation and subject to the provisions of the DGCL, our board of directors (the “Board”) has the authority, without stockholder approval (but without limitation of the rights of any party to the Shareholders Agreement and the Exchange Agreement), to issue additional shares of Class A Common Stock. Unless the Board determines otherwise, we will issue all shares of our capital stock in uncertificated form.

As of May 31, 2023, our issued and outstanding share capital consisted of (i) 69,921,386 shares of Class A Common Stock, (ii) 394,448,481 shares of Class B Common Stock and (iii) no shares of Preferred Stock.

Common Stock

We have two classes of authorized Common Stock: Class A Common Stock and Class B Common Stock, each of which has one vote per share. All classes of Common Stock vote together as a single class on all matters submitted to a vote of stockholders, except as otherwise required by applicable law, including in connection with amendments to the Certificate of Incorporation that increase or decrease the par value of the shares of such class, or alter or change the powers, preferences or special rights of the shares of such class so as to affect them adversely.

In order to preserve the Up-C structure, the Exchange Agreement provides that we and GBT JerseyCo will take (or, in some cases, forbear from taking) various actions, as necessary to maintain a one-to-one ratio between the number of issued and outstanding (x) Class A Stock (and equivalents) and the GBT JerseyCo A Ordinary Shares and (y) Class B Stock and the GBT JerseyCo B Ordinary Shares. For example, the Exchange Agreement provides that, if we issue or sell additional shares of Class A Common Stock, we will contribute the net proceeds of such issuance and sale to GBT JerseyCo, and GBT JerseyCo will issue to us an equal number of GBT JerseyCo A Ordinary Shares. Similarly, the Exchange Agreement provides that neither we nor GBT JerseyCo may effect any subdivision or combination of any of its equity securities unless the other effects an identical subdivision or combination of the corresponding class of its equity securities.

Class A Common Stock

Holders of shares of Class A Common Stock are entitled to one vote for each share held of record on all matters on which stockholders are entitled to vote generally, including in the election or removal of directors elected by our stockholders generally. The holders of Class A Common Stock do not have cumulative voting rights in the election of directors.

TABLE OF CONTENTS

Holders of shares of Class A Common Stock are entitled to receive dividends when, as and if declared by the Board out of funds legally 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.

In the case of our liquidation, dissolution or winding up and after payment in full of all amounts required to be paid to creditors and to the holders of preferred stock having liquidation preferences, if any, the holders of shares of Class A Common Stock will be entitled to receive, ratably on a per share basis with other holders of Class A Common Stock (subject to the nominal economic rights of holders of the Class B Common Stock described below), our remaining assets available for distribution to stockholders.

All shares of Class A Common Stock that are outstanding are fully paid and non-assessable. The Class A Common Stock will not be subject to further calls or assessments by us. Except as set forth in the Shareholders Agreement and the Exchange Agreement, holders of shares of Class A Common Stock do not have preemptive, subscription, redemption or conversion rights. There will be no redemption or sinking fund provisions applicable to the Class A Common Stock. The rights powers, preferences and privileges of Class A Common Stock will be subject to those of the holders of any shares of our preferred stock or any other series or class of stock we may authorize and issue in the future.

Class B Common Stock

Holders of shares of Class B Common Stock are entitled to one vote for each share held of record on all matters on which stockholders are entitled to vote generally, including in the election or removal of directors elected by our stockholders generally. The holders of Class B Common Stock do not have cumulative voting rights in the election of directors.

The shares of Class B Common Stock generally have only nominal economic rights (limited to the right to receive up to the par value in the event of our liquidation, dissolution or winding up). Dividends and other distributions shall not be declared or paid on Class B Common Stock. Holders of shares of Class B Common Stock have the right to receive, ratably on a per share basis with other holders of Class B Common Stock and holders of Class A Common Stock, a distribution from our remaining assets available for distribution to stockholders, up to the par value of such shares of Class B Common Stock, but otherwise are not entitled to receive any of our assets in connection with any such liquidation, dissolution or winding up.

Preferred Stock

No shares of Preferred Stock are issued or outstanding. The Certificate of Incorporation authorizes the Board to establish one or more series of preferred stock (including convertible preferred stock). An accompanying prospectus supplement will describe the specific terms of the shares of preferred stock offered through that prospectus supplement. If there are differences between the prospectus supplement relating to

TABLE OF CONTENTS

a particular series of preferred stock and this prospectus, the prospectus supplement will control. We will file a copy of the certificate of amendment to our certificate of incorporation that contains the terms of each new series of preferred stock with the Secretary of the State of Delaware and with the SEC each time we issue a new series of preferred stock. Each such certificate of amendment will establish the number of shares included in a designated series and fix the designation, powers, privileges, preferences and rights of the shares of each series as well as any applicable qualifications, limitations or restrictions. You should refer to the applicable certificate of amendment as well as our certificate of incorporation before deciding to buy shares of our preferred stock as described in any accompanying prospectus supplement. For more information on how you can obtain copies of such documents, see “Where You Can Find More Information” and “Incorporation of Certain Information by Reference.” We urge you to read the applicable certificates and any accompanying prospectus supplement in their entirety.

The Certificate of Designations for the Class A-1 Preferred Stock and the Certificate of Designations for the Class B-1 Preferred Stock are part of our Certificate of Incorporation and authorize the issuance of 3,000,000,000 shares of Class A-1 Preferred Stock and 3,000,000,000 shares of Class B-1 Preferred Stock, respectively.

Holders of Class A-1 Preferred Stock and Class B-1 Preferred Stock have no voting rights except as otherwise from time to time required by law.

Except as set forth in the Certificate of Designations, and as described below, holders of Class A-1 Preferred Stock are entitled to the same rights and privileges, qualifications and limitations as holders of Class A Common Stock and holders of Class B-1 Preferred Stock are entitled to the same rights and privileges, qualifications and limitations as holders of Class B Common Stock, as provided for in our Certificate of Incorporation, Bylaws, applicable law or otherwise and Class A-1 Preferred Stock shall be identical in all respects to the Class A Common Stock and Class B-1 Preferred Stock shall be identical in all respects to the Class B Common Stock.

In the event of any binding share exchange or reclassification involving the Class A-1 Preferred Stock or the Class B-1 Preferred Stock, merger or consolidation of us with another entity (whether or not a corporation) or conversion, transfer, domestication or continuance of us into another entity or into another jurisdiction, in each case, in connection with which holders of Class A Common Stock or Class B Common Stock, as applicable, would receive shares of capital stock that constitute “voting securities” (as such term is used for purposes of the BHC Act) (or options, rights or warrants to purchase, or of securities convertible into or exercisable or exchangeable for, such shares of capital stock), we may provide for the holders of shares of Class A-1 Preferred Stock or the Class B-1 Preferred Stock, as applicable, to receive, in lieu thereof, on a per share basis, the same number of shares of capital stock of another class or series that constitute “nonvoting securities” (as such term is used for purposes of the BHC Act) (or options, rights or warrants to purchase, or securities convertible into or exercisable or exchangeable for, such shares of capital stock), and that otherwise have the same rights and privileges, qualifications and limitations as the shares of capital stock to be received by the holders of Class A Common Stock or Class B Common Stock, as applicable.

In the event any rights, qualifications or limitations would result in the holders of Class A-1 Preferred Stock or the Class B-1 Preferred Stock, as applicable, receiving voting securities in connection with any dividend or distribution by us, such holders shall receive, in lieu of such voting securities, non-voting securities that are otherwise entitled to the same rights, privileges and qualifications as such voting securities subject to the limitations on voting described above.

In the event that the shares of Class A Common Stock or Class B Common Stock shall be split, divided, or combined, substantially concurrently therewith, the outstanding shares of the Class A-1 Preferred Stock or the Class B-1 Preferred Stock, as applicable, shall be proportionately split, divided or combined.

per share of Class A-1 Preferred Stock and (ii) the distribution to “Participating Shares” contemplated by Section 5.3(c)(i) of the Certificate of Incorporation. For purposes of calculating the amount pursuant to clause (ii) of the immediately preceding sentence, it shall be assumed that all then outstanding shares of Class A-1 Preferred Stock shall have been converted into Class A Common Stock and (b) the holders of Class B-1 Preferred Stock shall be entitled to receive a distribution from our remaining assets, before any payment shall be made to the holders of Common Stock by reason of their ownership thereof, up to the par value of Class B-1 Preferred Stock plus $0.0001 per share of Class B-1 Preferred Stock. Other than as set forth in the preceding sentence, the holders of shares of Class B-1 Preferred Stock, as such, shall not be entitled to receive any of our assets in the event of any voluntary or involuntary liquidation, dissolution or winding up of our affairs. If upon any such liquidation, dissolution or winding up, the assets available for distribution to our stockholders shall be insufficient to pay to holders of shares of Class A-1 Preferred Stock or Class B-1 Preferred Stock, as applicable, the full amount to which they shall be entitled, the holders of shares of Class A-1 Preferred Stock or the Class B-1 Preferred Stock, as applicable, shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full.

Shares of Class A-1 Preferred Stock and Class B-1 Preferred Stock are not convertible into Common Stock other than in connection with a Permitted BHCA Transfer (as defined below). Any holder of shares of Class A-1 Preferred Stock or Class B-1 Preferred Stock may transfer such shares in a Permitted BHCA Transfer to a Permitted BHCA Transferee (as defined below), and any shares of Class A-1 Preferred Stock or Class B-1 Preferred Stock so transferred shall immediately following such transfer automatically be converted into an equal number of shares of Class A Common Stock or Class B Common Stock, respectively. A “Permitted BHCA Transferee” shall mean a person or entity who acquires shares of Class A-1 Preferred Stock or Class B-1 Preferred Stock from a holder thereof in any of the following transfers (each a “Permitted BHCA Transfer”): (i) a widespread public distribution; (ii) a transfer to us; (iii) a transfer in which no transferee (or group of associated transferees) would receive 2% or more of the outstanding securities of any “class of voting securities” of ours (as such term is used for purposes of the BHC Act); or (iv) a transfer to a transferee who would control more than 50% of every “class of voting securities” (as such term is used for purposes of the BHC Act) of us without giving effect to the shares of our capital stock transferred by the applicable transferred stockholder or any of its Permitted BHCA Transferees.

The Certificate of Incorporation authorizes the Board to establish one or more series of preferred stock (including convertible preferred stock). Subject to any limitations prescribed by the DGCL, the authorized shares of preferred stock are available for issuance without further action by the holders of our Class A Common Stock or Class B Common Stock. The Board may fix the number of shares constituting a series of preferred stock and the designation of such series, the voting powers (if any) of the shares of such series and the powers, preferences and relative, participating, optional or other special rights, if any, and any qualifications, limitations or restrictions thereof.

We could issue a series of preferred stock that could, depending on the terms of the series, impede or discourage an acquisition attempt or other transaction that some, or a majority, of the holders of our Class A Common Stock might believe to be in their best interests or in which the holders of our Class A Common Stock might receive a premium over the market price of the shares of our Class A Common Stock. Additionally, the issuance of preferred stock may adversely affect the rights of holders of our Class A Common Stock by restricting dividends on the Class A Common Stock, diluting the voting power of the Class A Common Stock or, as is the case with the Class A-1 Preferred Stock and the Class B-1 Preferred Stock, subordinating the liquidation rights of the Class A Common Stock. As a result of these or other factors, the issuance of preferred stock could have an adverse impact on the market price of Class A Common Stock.

Dividend Rights

The DGCL permits a corporation to declare and pay dividends out of “surplus” or, if there is no “surplus,” out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. “Surplus” is defined as the excess of the net assets of the corporation over the amount determined to be the capital of the corporation by its board of directors. The capital of the corporation is typically

TABLE OF CONTENTS

calculated to be (and cannot be less than) the aggregate par value of all issued shares of capital stock. Net assets equal the fair value of the total assets minus total liabilities. The DGCL also provides that dividends may not be paid out of net profits if, after the payment of the dividend, remaining capital would be less than the capital represented by the outstanding stock of all classes having a preference upon the distribution of assets. Declaration and payment of any dividends will be subject to the discretion of the Board.

We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends from future earnings for the foreseeable future. In addition, our ability to pay dividends is limited by that certain senior secured credit agreement, dated as of August 13, 2018, by and among GBT Group Services B.V., as borrower, GBT III B.V., as the original parent guarantor, the other loan parties from time to time party thereto, Morgan Stanley Senior Funding, Inc., as administrative agent and as collateral agent, and the lenders and letter of credit issuers from time to time party thereto, as amended from time to time. and may be limited by covenants under other indebtedness we and our subsidiaries incur in the future, as well as other limitations and restrictions imposed by law.

Annual Stockholder Meetings

Our Bylaws provide that annual stockholder meetings will be held on a date and at a time and place, if any, as exclusively selected by the Board. To the extent permitted under applicable law, we may conduct meetings by remote communications, including by webcast.

Anti-Takeover Effects of Provisions of Delaware Law and our Certificate of Incorporation and Bylaws

Our Certificate of Incorporation and our Bylaws contain certain provisions that are intended to enhance the likelihood of continuity and stability in the composition of the Board and which may have the effect of delaying, deferring or preventing a future takeover or change in control of the Company unless such takeover or change in control is approved by the Board. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile or abusive change of control and enhance the ability of the Board to maximize stockholder value in connection with any unsolicited offer to acquire us. However, these provisions may have an anti-takeover effect and may delay, deter or prevent a merger or acquisition of the Company by means of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the prevailing market price for the shares of Class A Common Stock held by stockholders.

These provisions include:

Action by Written Consent; Special Meetings of Stockholders

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 or are 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 the corporation’s certificate of incorporation provides otherwise. Our Certificate of Incorporation provides that stockholder action can be taken only at an annual or special meeting of stockholders and cannot be taken by written consent in lieu of a meeting (with exceptions for (i) actions taken by holders of a series of preferred stock, as provided by the applicable certificate of designation, and (ii) actions required or permitted to be taken by holders of Class B Common Stock separately as a class but only if such action were taken by holders of at least 662∕3% of the total voting power of all the Class B Common Stock then, outstanding). Our Certificate of Incorporation and our Bylaws also provide that, except as otherwise required by law, special meetings of the stockholders can be called only by or at the direction of the Board pursuant to a resolution adopted by a majority of the total number of directors. Stockholders will not be permitted to call a special meeting or to require the Board to call a special meeting. Our Bylaws prohibit the conduct of any business at a special meeting other than as specified at the notice for such meeting. These provisions may have the effect of deterring, delaying or discouraging hostile takeovers or changes in control of the Company.

TABLE OF CONTENTS

Election and Removal of Directors

Our Certificate of Incorporation provides that our directors may be removed only for cause and only by the affirmative vote of at least 662∕3% of the votes that all our stockholders would be entitled to cast in an annual election of directors, voting together as a single class, at a meeting of the stockholders called for that purpose. This requirement of a supermajority vote to remove directors could enable a minority of our stockholders to prevent a change in the composition of the Board. In addition, our Certificate of Incorporation and our Bylaws provide that any vacancies on the Board will be filled only by the affirmative vote of a majority of the remaining directors, even if less than a quorum, or by a sole remaining director or at a special meeting of stockholders called by or at the direction of the Board for such purpose. Moreover, under our Certificate of Incorporation, the Board is divided into three classes of directors, each of which will hold office for a three-year term. The existence of a classified board could delay a successful tender offeror from obtaining majority control of the Board, and the prospect of that delay might deter a potential offeror.

No Cumulative Voting

Under Delaware law, the right to vote cumulatively does not exist unless the certificate of incorporation specifically authorizes cumulative voting. Our Certificate of Incorporation does not authorize cumulative voting. Therefore, stockholders holding a majority in voting power of the shares of our Class A Common Stock entitled to vote generally in the election of directors will be able to elect all of our directors.

Advance Notice Procedures

Our Bylaws establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to the Board. Stockholders at an annual meeting will only be able to consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the Board or by a stockholder who was a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has given our secretary timely written notice, in proper form, of the stockholder’s intention to bring that business before the meeting. Generally, to be timely, a stockholder’s notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the immediately preceding annual meeting of stockholders. Our Bylaws also specify requirements as to the form and content of a stockholder’s notice. Although our Bylaws do not give the Board the power to approve or disapprove stockholder nominations of candidates or proposals regarding other business to be conducted at a special or annual meeting, our Bylaws may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of the Company.

Supermajority Approval Requirements

The DGCL generally provides that the affirmative vote of a majority of the shares entitled to vote thereon is required to amend a corporation’s certificate of incorporation, unless the corporation’s certificate of incorporation or bylaws requires a greater percentage. The DGCL does not specify a required vote for stockholders to amend a corporation’s bylaws and, therefore, the default voting standard set forth in a corporation’s bylaws will apply to votes to amend the bylaws unless the certificate of incorporation or bylaws provide otherwise. In addition, the DGCL provides that a board of directors may amend the bylaws without further stockholder action if authorized to do so by the corporation’s certificate of incorporation. Our Certificate of Incorporation provides that, without limiting the rights of any party to the Shareholders Agreement, a majority vote of the Board or the affirmative vote of holders of at least 662∕3% of the total votes of the outstanding shares of our capital stock entitled to vote with respect thereto, voting together as a single class, will be required to amend, alter, change or repeal our Bylaws or adopt any provision inconsistent therewith. In addition, our Certificate of Incorporation provides that, without limiting the rights of any party to the Shareholders Agreement, the affirmative vote of the holders of at least 662∕3% of the total votes of the outstanding shares of our capital stock entitled to vote with respect thereto, voting together as a single class, will be required to amend our Certificate of Incorporation (and, in addition, the affirmative

TABLE OF CONTENTS

vote of the holders of at least 662∕3% of the total voting power of the Class B Common Stock, voting separately as a class, will be required to amend any provision of the Certificate of Incorporation that adversely affects the rights, priorities or privileged of the Class B Common Stock). This requirement of a supermajority vote to approve amendments to our bylaws and certificate of incorporation could enable a minority of our stockholders to exercise veto power over any such amendments.

These provisions may have the effect of deterring hostile takeovers or delaying or preventing changes in control of us or our management, such as a merger, reorganization or tender offer. These provisions are intended to enhance the likelihood of continued stability in the composition of the Board and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of the Company. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions are also intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of Class A Common Stock that could result from actual or rumored takeover attempts. Such provisions may also have the effect of preventing changes in our management.

Authorized but Unissued Shares

Delaware law does not require stockholder approval for any issuance of shares that are authorized and available for issuance. However, the listing requirements of the NYSE, which would apply if and so long as Class A Common Stock remains listed on the NYSE, require stockholder approval prior to the issuance of shares of Class A Common Stock in certain circumstances, including (i) if the number of shares of Class A Common Stock to be issued is, or will be upon issuance, equal to or in excess of 20% of the number of shares of Class A Common Stock outstanding before the issuance and (ii) if such issuance is to a person considered a Related Party (as defined in Rule 312.03 of the NYSE Listed Company Manual) solely by virtue of being a substantial security holder of the issuer and the number of shares of Class A Common Stock to be issued exceeds five percent of the number of shares of Class A Common Stock outstanding before the issuance.

The Board may generally issue preferred shares on terms calculated to discourage, delay or prevent a change of control of the Company or the removal of our management. Moreover, our authorized but unissued shares of preferred stock will be available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, to facilitate acquisitions and employee benefit plans.

Our authorized but unissued shares of Class A Common Stock will be available for future issuance without stockholder approval. These additional shares may be used for a variety of corporate purposes, including future public offerings to raise additional capital and corporate acquisitions. The existence of authorized but unissued shares of Class A Common Stock could render more difficult or discourage an attempt to obtain control of a majority of our Class A Common Stock by means of a proxy contest, tender offer, merger or otherwise.

Dissenters’ Rights of Appraisal and Payment

Under the DGCL, with certain exceptions, our stockholders will have appraisal rights in connection with a merger or consolidation of us. Pursuant to the DGCL, stockholders who properly request and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery.

Stockholders’ Derivative Actions

Under the DGCL, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholders’ stock thereafter devolved by operation of law.

TABLE OF CONTENTS

Exclusive Forum

Our Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Delaware Court of Chancery shall, to the fullest extent permitted by applicable law, be the sole and exclusive forum for any (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, other employee or stockholder of ours to us or our stockholders, or any claim for aiding and abetting such alleged breach, (3) any action asserting a claim arising under any provision of the DGCL, Certificate of Incorporation or our Bylaws or as to which the DGCL confers jurisdiction on the Delaware Court of Chancery, (4) any action to interpret, apply, enforce or determine the validity of our Certificate of Incorporation or our Bylaws, (5) any action asserting a claim governed by the internal affairs doctrine of the law of the State of Delaware or (6) any action asserting an “internal corporate claim” as defined in Section 115 of the DGCL. Our Certificate of Incorporation further provides that, (i) such exclusive forum provision shall not apply to claims or causes of action brought to enforce a duty or liability created by the Securities Act or the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction and (ii) to the fullest extent permitted by law, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States shall be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. We note that our investors and stockholders cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and to have consented to the provisions of our Certificate of Incorporation described above. Although we believe these provisions benefit us by providing increased consistency in the application of Delaware law for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against our directors and officers. 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, in connection with one or more actions or proceedings described above, a court could find the choice of forum provisions contained in our Certificate of Incorporation to be inapplicable or unenforceable. For example, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. Accordingly, there is uncertainty as to whether a court would enforce such a forum selection provision as written in connection with claims arising under the Securities Act.

Registration Rights

Pursuant to the Registration Rights Agreement and the Subscription Agreements, we are obligated to, among other things, register for resale certain securities that are held by the Sponsor, any other parties to the Registration Rights Agreement and the PIPE Investors. Subject to certain exceptions, we will bear all registration expenses under the Registration Rights Agreement. See the section titled “Certain Relationships and Related Party Transactions — Related Party Transactions — Registration Rights Agreement” in our Proxy Statement incorporated by reference herein for a description of these registration rights.

Conflicts of Interest

Delaware law permits corporations to adopt provisions renouncing any interest or expectancy in certain opportunities that are presented to the corporation or its officers, directors or stockholders. Our Certificate of Incorporation, to the maximum extent permitted by applicable law, renounces any interest or expectancy that we have in, or right to be offered an opportunity to participate in, business opportunities that are from time to time presented to our officers, directors or stockholders or their respective affiliates, other than those officers, directors, stockholders or affiliates who are our or our subsidiaries’ employees. Our Certificate of Incorporation provides that, subject to the terms thereof, to the fullest extent permitted by law, none of our non-employee directors (including any non-employee director who serves as one of our officers in both his or her director and officer capacities) or his or her affiliates will have any duty to refrain from (1) engaging in a corporate opportunity in the same or similar lines of business in which we or our affiliates now engage or propose to engage or (2) otherwise competing with us or our affiliates. In addition, to the fullest extent permitted by law, subject to the terms of our Certificate of Incorporation, and without

TABLE OF CONTENTS

limiting any separate agreement to between any person and us or any of our subsidiaries, no non-employee director will (i) have any duty to present business opportunities to us or our subsidiaries or (ii) be liable to us, any of our stockholders or any other person who acquires an interest in our stock, by reason of the fact that such person pursues or acquires a business opportunity for itself, directs such opportunity to another person or does not communicate such opportunity or information to us or any of our subsidiaries. Our Certificate of Incorporation does not renounce our interest in any business opportunity that is expressly offered to a non-employee director or officer solely in his or her capacity as a director or officer of, through his or her service to, or pursuant to a contract with, the Company.

Limitations on Liability and Indemnification of Officers and Directors

The DGCL authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of directors’ fiduciary duties, subject to certain exceptions. Our Certificate of Incorporation includes a provision that eliminates the personal liability of directors for monetary damages to the Company or its stockholders for any breach of fiduciary duty as a director to the maximum extent permitted by the DGCL from time to time. The effect of these provisions is to eliminate the rights of us and our stockholders, through stockholders’ derivative suits on our behalf, to recover monetary damages from a director for breach of fiduciary duty as a director, including breaches resulting from grossly negligent behavior. The DGCL does not permit a corporation to eliminate or limit the liability of a director who has acted in bad faith, engaged in intentional misconduct, knowingly violated the law, authorized illegal dividends or redemptions or derived an improper benefit from his or her actions as a director. If, however, the DGCL is amended to permit a corporation to eliminate or limit a director’s liability for any such conduct, then the exculpation provisions in our Certificate of Incorporation will function automatically to eliminate our directors’ personal liability to the Company and its stockholder for such conduct.

Our Certificate of Incorporation and our Bylaws generally provide that we must indemnify and advance expenses to our directors and officers to the fullest extent authorized by the DGCL. We are also expressly authorized to carry directors’ and officers’ liability insurance providing indemnification for our directors, officers and certain employees for some liabilities. In addition, in the event that one of our directors or officers may have certain rights to indemnification, advancement of expenses and/or insurance provided by other persons (collectively, the “Other Indemnitors”), with respect to the rights to indemnification, advancement of expenses and/or insurance set forth in our Certificate of Incorporation and our Bylaws, the Company: (i) shall be the indemnitor of first resort (i.e., its obligations to any such director or officer are primary and any obligation of the Other Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by such director or officer are secondary); and (ii) shall be required to advance and indemnify the full amounts to which such director or officer are entitled under our Certificate of Incorporation and our Bylaws, without regard to any rights such director or officer may have against any of the Other Indemnitors. We believe that these indemnification and advancement provisions and insurance are useful to attract and retain qualified directors and executive officers.

The limitation of liability, indemnification and advancement provisions in our Certificate of Incorporation and our Bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

We have entered into indemnification agreements with each of our directors and executive officers. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors or executive officers, we have been informed that in the opinion of the SEC such indemnification is against public policy and is therefore unenforceable.

There is currently no pending material litigation or proceeding involving any of our directors, officers or employees for which indemnification is sought.

TABLE OF CONTENTS

Section 203 of the DGCL

In general, Section 203 of the DGCL 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. A “business combination” includes, among other things, a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns, or did own within three years prior to the determination of interested stockholder status, 15% or more of the corporation’s voting stock. For purposes of this section only, “voting stock” has the meaning given to it in Section 203 of the DGCL.

A Delaware corporation may “opt out” of Section 203 of the DGCL with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or bylaws resulting from a stockholders’ amendment approved by at least a majority of the outstanding voting shares. We have elected not to be governed by Section 203 of the DGCL. Our Certificate of Incorporation, however, includes provisions similar to Section 203 of the DGCL that generally prohibit us from engaging in any of a broad range of business combinations with an interested stockholder for a period of three years following the date on which the stockholder becomes an interested stockholder, unless (i) such person became an interested stockholder as a result of a transaction approved by the Board (other than the Business Combination), (ii) such person acquired at least 85% of our voting stock (excluding shares owned by our officers and directors and employee stock plans) in the transaction by which such person became an interested stockholder or (iii) such transactions are approved by the Board and the affirmative vote of at least 662∕3% of our outstanding voting stock (other than such stock owned by the interested stockholder). In general, a person and its affiliates and associates will be an “interested stockholder” under our Certificate of Incorporation if such person (a) holds at least 15% of our voting stock or is an affiliate or associate of ours and (b) held at least 15% of our voting stock at any time during the three-year period preceding the date on which it is sought to be determined whether such person is an interested stockholder; however, a person that acquires greater than 15% of our voting stock solely as a result of actions taken by us will not be an interested stockholder unless such person thereafter acquires additional shares of voting stock other than as a result of further corporate action not caused by such person. Further, the foregoing restrictions will not apply if the business combination is with a person who became an interested stockholder as a result of the Business Combination (provided such person does not acquire more than an additional 1% of the outstanding shares of our voting stock after the date of the Closing). As a result, mergers or other takeover or change in control attempts of us may be discouraged or prevented.

Transfer Agent and Registrar

The transfer agent and registrar for our capital stock is Continental Stock Transfer & Trust Company.

Listing

Our Class A Common Stock is listed on the NYSE under the symbol “GBTG”.

TABLE OF CONTENTS

DESCRIPTION OF DEPOSITARY SHARES

We may offer depositary receipts representing fractional shares of our preferred stock, rather than full shares of preferred stock. The shares of preferred stock represented by depositary shares will be deposited under a depositary agreement between us and a bank or trust company that meets certain requirements and is selected by us (the “Bank Depositary”). Each owner of a depositary share will be entitled to all the rights and preferences of the preferred stock represented by the depositary share.

The description in an accompanying prospectus supplement of any depositary shares we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable depositary agreement, which will be filed with the SEC if we offer depositary shares. For more information on how you can obtain copies of any depositary agreement if we offer depositary shares, see “Where You Can Find More Information” and “Incorporation of Certain Information by Reference.” We urge you to read the applicable depositary agreement and any accompanying prospectus supplement in their entirety.

Dividends and Other Distributions

If we pay a cash distribution or dividend on a series of preferred stock represented by depositary shares, the Bank Depositary will distribute such dividends to the record holders of such depositary shares. If the distributions are in property other than cash, the Bank Depositary will distribute the property to the record holders of the depositary shares. However, if the Bank Depositary determines that it is not feasible to make the distribution of property, the Bank Depositary may, with our approval, sell such property and distribute the net proceeds from such sale to the record holders of the depositary shares.

Redemption of Depositary Shares

If we redeem a series of preferred stock represented by depositary shares, the Bank Depositary will redeem the depositary shares from the proceeds received by the Bank Depositary in connection with the redemption. The redemption price per depositary share will equal the applicable fraction of the redemption price per share of the preferred stock. If fewer than all the depositary shares are redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as the Bank Depositary may determine.

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of the preferred stock represented by depositary shares are entitled to vote, the Bank Depositary will mail the notice to the record holders of the depositary shares relating to such preferred stock. Each record holder of these depositary shares on the record date, which will be the same date as the record date for the preferred stock, may instruct the Bank Depositary as to how to vote the preferred stock represented by such holder’s depositary shares. The Bank Depositary will endeavor, insofar as practicable, to vote the amount of the preferred stock represented by such depositary shares in accordance with such instructions, and we will take all action that the Bank Depositary deems necessary in order to enable the Bank Depositary to do so. The Bank Depositary will abstain from voting shares of the preferred stock to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred stock.

Amendment and Termination of the Depositary Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the depositary agreement may be amended by agreement between the Bank Depositary and us. However, any amendment that materially and adversely alters the rights of the holders of depositary shares will not be effective unless such amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. The depositary agreement may be terminated by the Bank Depositary or us only if (1) all outstanding depositary shares have been redeemed or (2) there has been a final distribution in respect of the preferred stock in connection with any liquidation, dissolution or winding up of our company and such distribution has been distributed to the holders of depositary receipts.

Withdrawal of Preferred Stock

Except as may be provided otherwise in an accompanying prospectus supplement, upon surrender of depositary receipts at the principal office of the Bank Depositary, subject to the terms of the depositary

TABLE OF CONTENTS

agreement, the owner of the depositary shares may demand delivery of the number of whole shares of preferred stock and all money and other property, if any, represented by those depositary shares. Partial shares of preferred stock will not be issued. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the Bank Depositary will deliver to such holder at the same time a new depositary receipt evidencing the excess number of depositary shares. Holders of withdrawn preferred stock may not thereafter deposit those shares under the depositary agreement or receive depositary receipts evidencing depositary shares therefor.

DESCRIPTION OF DEBT SECURITIES

We may offer debt securities in one or more series, which may be senior debt securities or subordinated debt securities and which may be convertible into another security.

The following description briefly sets forth certain general terms and provisions of the debt securities. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which the following general terms and provisions may apply to the debt securities, will be described in an accompanying prospectus supplement.

•

our obligation or right to redeem, purchase or repay debt securities under a sinking fund, amortization or analogous provision;

•

any restriction or conditions on the transferability of the debt securities;

General

We may sell the debt securities, including original issue discount securities, at par or at a substantial discount below their stated principal amount. Unless we inform you otherwise in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series or any other series outstanding at the time of issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of securities under the indenture.

We will describe in an accompanying prospectus supplement any other special considerations for any debt securities we sell that are denominated in a currency or currency unit other than U.S. dollars. In addition, debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of such securities may receive a principal amount or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable currencies, commodities, equity indices or other factors. Information as to the methods for determining the amount of principal or interest, if any, payable on any date, and the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked will be described in an accompanying prospectus supplement.

United States federal income tax consequences and special considerations, if any, applicable to any such series will be described in an accompanying prospectus supplement.

We expect most debt securities to be issued in fully registered form without coupons and in denominations of $1,000 and any integral multiple of $1,000 in excess thereof. Subject to the limitations provided in the indenture and in an accompanying prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the designated corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

Global Securities

Unless we inform you otherwise in an accompanying prospectus supplement, the debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in an accompanying prospectus supplement. Unless and until a global security is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of shares of our Class A Common Stock, shares of preferred stock or our debt securities. We may issue warrants independently or together with other securities, and they may be attached to or separate from the other securities. Each series of warrants will be issued under a separate warrant agreement that we will enter into with a bank or trust company, as warrant agent, as detailed in an accompanying prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation, or agency or trust relationship, with you.

The prospectus supplement relating to a particular issue of warrants will describe the terms of those warrants, including, when applicable:

•

the offering price;

•

the currency or currencies, including composite currencies, in which the purchase price and/or exercise price of the warrants may be payable;

•

the number of warrants offered;

•

the exercise price and the amount of securities you will receive upon exercise;

•

the procedure for exercise of the warrants and the circumstances, if any, that will cause the warrants to be automatically exercised;

•

the rights, if any, we have to redeem the warrants;

•

the date on which the right to exercise the warrants will commence and the date on which the warrants will expire;

•

the name of the warrant agent; and

•

any other material terms of the warrants.

After warrants expire they will become void. The prospectus supplement may provide for the adjustment of the exercise price of the warrants.

Warrants may be exercised at the appropriate office of the warrant agent or any other office indicated in an accompanying prospectus supplement. Before the exercise of warrants, holders will not have any of the rights of holders of the securities purchasable upon exercise and will not be entitled to payments made to holders of those securities.

The description in an accompanying prospectus supplement of any warrants we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable warrant agreement, which will be filed with the SEC if we offer warrants. For more information on how you can obtain copies of any warrant agreement if we offer warrants, see “Where You Can Find More Information” and “Incorporation of Certain Information by Reference.” We urge you to read the applicable warrant agreement and any accompanying prospectus supplement in their entirety.

DESCRIPTION OF PURCHASE CONTRACTS AND PURCHASE UNITS

We may issue purchase contracts, including contracts obligating holders to purchase from us, and obligating us to sell to the holders, a specified number of shares of our Class A Common Stock, shares of our preferred stock or our debt securities at a future date or dates, which we refer to in this prospectus as purchase contracts. The price of the securities and the number of securities may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula set forth in the purchase contracts and may be subject to adjustment under anti-dilution formulas. The purchase contracts may be issued separately or as part of units consisting of a stock purchase contract and our debt securities or preferred securities or debt obligations of third parties, including U.S. treasury securities, or any combination of the foregoing, securing the holders’ obligations to purchase the securities under the purchase contracts, which we refer to herein as purchase units. The purchase contracts may require holders to secure their obligations under the purchase contracts in a specified manner. The purchase contracts also may require us to make periodic payments to the holders of the purchase contracts or the purchase units, as the case may be, or vice versa, and those payments may be unsecured or pre-funded in whole or in part.

The description in an accompanying prospectus supplement of any purchase contract or purchase unit we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable purchase contract or purchase unit, which will be filed with the SEC if we offer purchase contracts or purchase units. For more information on how you can obtain copies of any purchase contract or purchase unit we may offer, see “Where You Can Find More Information” and “Incorporation of Certain Information by Reference.” We urge you to read the applicable purchase contract or applicable purchase unit and any accompanying prospectus supplement in their entirety.

SELLING STOCKHOLDERS

This prospectus relates to the sale or other disposition of up to 3,775,304 shares of our Class A Common Stock by the selling stockholders named below, and their donees, pledgees, or other successors-in-interest selling shares of Class A Common Stock or interests in shares of Class A Common Stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer.

The following table, based upon information currently known by us, sets forth as May 31, 2023, (i) the number of shares held of record or beneficially by the selling stockholders as of such date (as determined below) and (ii) the number of shares that may be sold or otherwise disposed of under this prospectus by the selling stockholders. Percentage ownership is based on 69,921,386 shares of Class A Common Stock outstanding as of May 31, 2023, plus securities deemed to be outstanding with respect to individual stockholders pursuant to Rule 13d-3(d)(1) under the Exchange Act. Beneficial ownership includes shares of Class A Common Stock plus any securities held by the holder exercisable for or convertible into shares of Class A Common Stock within 60 days after May 31, 2023, in accordance with Rule 13d-3(d)(1) under the Exchange Act. The inclusion of any shares in this table does not constitute an admission of beneficial ownership for the selling stockholders named below. We do not know when or in what amounts a selling stockholder may sell or otherwise dispose of the shares of Class A Common Stock covered hereby. The selling stockholders may not sell or otherwise dispose of any or all of the shares offered by this prospectus and may sell or otherwise dispose of shares covered hereby in transactions exempt from the registration requirements of the Securities Act. Because the selling stockholders may sell or otherwise dispose of some, all or none of the shares covered hereby, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the shares, we cannot estimate the number of the shares that will be held by the selling stockholders after completion of the offering. However, for purposes of the following table, we have assumed that all of the shares covered hereby are sold by the selling stockholders.

Except as described in the footnotes in the table below, the selling stockholders have not held any position or office, or otherwise had a material relationship, with us or any of our subsidiaries within the past three years other than as a result of the ownership of our shares or other securities. Unless otherwise indicated below, to our knowledge, all persons named in the table have sole voting and investment power with respect to their shares of Class A Common Stock, except to the extent authority is shared by their spouses under applicable law.
