*Strategic Governance Agreement* 

On March 5, 2026 (the "Effective Date"), Sabre Corporation, a Delaware corporation (the "Company") entered into a Strategic Governance Agreement (the "Agreement") with Constellation Canadian Holdings Inc., an Ontario corporation and Constellation Software Inc., an Ontario corporation (each, a "Constellation Party," and collectively, the "Constellation Parties") pursuant to which, among other things, the Company agreed to, as promptly as practicable, but in any event no later than 10 business days following the Effective Date, take all necessary actions to appoint Damian McKay (the "New Director") as a member of the Company's board of directors (the "Board") with a term expiring at the Company's 2026 annual meeting of stockholders (the "2026 Annual Meeting"). In addition, the Company agreed to nominate the New Director for election at the 2026 Annual Meeting, recommend that the Company's stockholders vote to elect the New Director at the 2026 Annual Meeting and use its reasonable best efforts to obtain the election of the New Director at the 2026 Annual Meeting.

Pursuant to the Agreement, the Constellation Parties are subject to certain customary standstill restrictions, including that they will not acquire Beneficial Ownership (as defined in the Agreement) of and economic exposure to more than 15% of the Company's outstanding shares of Common Stock, par value $0.01 per share, in the aggregate, from the Effective Date until the later of (i) the earlier of (a) 30 days prior to the director nomination deadline for the Company's 2027 annual meeting of stockholders and (b) 120 days prior to the first anniversary of the 2026 Annual Meeting, and (ii) 10 days after the date on which the New Director ceases to serve on the Board (the "Specified Period"). The Constellation Parties have also agreed to vote in a manner consistent with the recommendation of the Board during the Specified Period; provided, however, that, except with respect to the 2026 Annual Meeting, if Institutional Shareholder Services Inc. ("ISS") and Glass Lewis & Co., LLC ("Glass Lewis") recommend otherwise with respect to any proposals (other than as related to the election or removal of directors), the Constellation Parties are permitted to vote in accordance with the ISS or Glass Lewis recommendation; provided, further, that the Constellation Parties are permitted to vote in their sole discretion on any proposal with respect to an Extraordinary Transaction (as defined in the Agreement) or that relates to the implementation of takeover defenses. The Agreement also contains certain customary mutual non-disparagement provisions and confidentiality provisions.

In addition, pursuant to the Agreement, in connection with the appointment of the New Director, the Constellation Parties irrevocably withdraw, and are deemed to have irrevocably withdrawn, the director nomination notice previously delivered to the Company. Further, pursuant to the Agreement, the Company agreed to within two business days after the Effective Date (the "Acceleration Date") amend the Rights Agreement, dated as of March 1, 2026 (the "Rights Agreement"), by and between the Company and Equiniti Trust Company, LLC, as rights agent (the "Rights Agent"), such that the Final Expiration Date (as defined in the Rights Agreement) is accelerated to the next immediate business day following the Acceleration Date.

On March 5, 2026, the Company entered into an amendment (the "Rights Agreement Amendment") to the Rights Agreement with the Rights Agent accelerating the expiration of the Rights Agreement and terminating the preferred stock purchase rights, effective at the close of business on March 6, 2026.

Mr. McKay will serve for an initial term expiring at the 2026 Annual Meeting or until his earlier resignation or removal. The Board also appointed Mr. McKay as a member of the Technology Committee of the Board.

The Board has determined that Mr. McKay is an independent director according to NASDAQ listing standards. As a director, Mr. McKay will participate in the Company's non-employee director compensation program. Currently under this program, he is entitled to receive an annual cash retainer of $90,000, as well as an annual cash retainer for service on committees of the Board. Also currently under the program, he is eligible to receive a restricted stock unit award on the date of his appointment to the Board, as well as beginning in 2027 an annual restricted stock unit award on the date of the Company's annual meeting of stockholder, in each case with a grant date value of $200,000 and vesting in full on the first anniversary of the date of grant. Other than the Agreement, there are no arrangements or understandings between Mr. McKay and other persons pursuant to which he was selected as a director and the Company is not aware of any transaction with the New Director that would require disclosure under Item 404(a) of Regulation S-K.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Company Policies</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The parties acknowledge that the New Director, upon election or appointment to the Board, will (except as expressly contemplated by this Agreement) be governed by and required to comply with the same protections and obligations regarding confidentiality, conflicts of interest, related person transactions, fiduciary duties, codes of conduct, trading and disclosure policies, director resignation policy, and other governance guidelines and policies of the Company as all other non-management directors of the Company (collectively, "Company Policies"), and shall have the same rights and benefits, including with respect to insurance, indemnification, compensation and fees as are applicable to all non-management directors of the Company. The Company agrees that, during the Specified Period, any changes to the Company Policies, or any new Company Policies, will be adopted in good faith and not for the purpose of undermining or conflicting with the arrangements contemplated hereby.

Concurrently with the New Director's appointment to the Board and as a condition to the Company's obligations under this Agreement, the New Director will execute and deliver an irrevocable letter of resignation (the "<u>Resignation Letter</u>") in the form attached hereto as <u>Exhibit</u> <u>B</u>, it being understood that it shall be in the Board's sole discretion whether to accept or reject such resignation. The Company's obligations under this <u>Section</u> <u>1</u> shall terminate, and the Constellation Parties shall have no appointment or nomination or other rights under this <u>Section</u> <u>1</u>, other than under <u>Section</u> <u>1(f)</u>, upon the effectiveness of any resignation by the New Director due the Board accepting the resignation of the New Director from the Board pursuant to the Resignation Letter.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Except as otherwise specified in this Agreement, if a replacement director (a "<u>Replacement Director</u>") is appointed to the Board pursuant to this <u>Section</u> <u>1(f)</u>, all reference in this Agreement to the term "New Director" will include such Replacement Director, as applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) The appointment of any Replacement Director shall be subject to (A) the execution and delivery by such Replacement Director of (x) a fully completed copy of the Company's standard director and officer questionnaire and other reasonable and customary director onboarding documentation required by the Company in connection with the appointment or election of all new non-management Board members (including, for the avoidance of doubt, a customary background check, (y) a written acknowledgment that such Replacement Director agrees to be bound by all Company Policies and (z) the Resignation Letter in the form attached as <u>Exhibit</u> <u>B</u> hereto, (B) such Replacement Director qualifying as "independent" pursuant to SEC rules and regulations and applicable stock exchange listing standards, and (C) the Nominating and Governance Committee of the Board (the "<u>Nominating Committee</u>") and the Board determining such Replacement Director to be reasonably acceptable (such acceptance not to be unreasonably withheld).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) The Nominating Committee, acting reasonably and in good faith, shall make its determination and recommendation regarding whether any candidate for Replacement Director so qualifies pursuant to clauses (B) and (C) of <u>Section</u> <u>1(f)(iii)</u> within 10 days after such candidate has submitted to the Company the documentation required by this <u>Section</u> <u>1(f)</u>.

For the purposes of this Agreement, the Constellation Parties agree that none of them shall be deemed to be legally required to disclose any Confidential Information solely by virtue of

------

the fact that, absent such disclosure, the Constellation Parties, any of their respective Affiliates or any Group of which any Constellation Party is a member (1) would be prohibited from purchasing, selling or engaging in derivative or other voluntary transactions with respect to the securities of the Company or any Debt Instruments of the Company or (2) would be unable to file any proxy materials or tender or exchange offer materials in compliance with Section 14 of the Exchange Act or the rules promulgated thereunder. Neither the Constellation Parties nor any of their respective Affiliates or any Group of which any Constellation Party is a member will file any Schedule 13D or other filing pursuant to applicable securities laws, or otherwise make any public statement, disclosing any of the Confidential Information.

Following the expiration of the Specified Period, upon written request of the Company, the Constellation Parties agree to (and agree to cause the Approved Constellation Persons to, if applicable) (i) promptly (and in any event within ten Business Days of such expiration) return or destroy, in the Company's sole discretion (and upon request by the Company, confirm in writing such return or destruction to the Company) all Confidential Information of the Company and its Affiliates in their possession (including, for the avoidance of doubt, that portion of any documents, materials and other items that contain Confidential Information), (ii) not to retain any copies, extracts or other reproductions in whole or in part, mechanical or electronic, of such written material, and (iii) to destroy all computer records, documents, memoranda, notes and other writings prepared by the New Director or an Approved Constellation Person that contain the Confidential Information of the Company or any of its Affiliates; <u>provided</u>*,* <u>however</u>*,* that Constellation Software and the Approved Constellation Persons shall be entitled to retain copies of all such Confidential Information in restricted access legal files or pursuant to automatic electronic archiving and back-up procedures or pursuant to Constellation Software's document retention policies; <u>provided</u>, that the Constellation Parties and the Approved Constellation Persons shall be subject to the confidentiality obligations of this <u>Section</u> <u>3</u> with respect to such retained Confidential Information for the period set forth in <u>Section</u> <u>3(f)</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) It is understood and agreed that the Company may, in its sole discretion, from time to time, on the advice of legal counsel, determine that disclosure of certain of its competitively sensitive Confidential Information by the New Director to Constellation Software or the Approved Constellation Persons can reasonably be expected to have adverse consequences to its business or under applicable law. In each such case, the Company may cause, in its sole discretion, (A) such competitively sensitive Confidential Information to be made available by the New Director to Constellation Software or the Approved Constellation Persons only in accordance with additional procedures mutually agreed by the New Director, and the Company in writing to permit disclosure of such competitively sensitive Confidential Information in an appropriate manner, or (B) the New Director to withhold sharing such competitively sensitive Confidential Information with Constellation Software or the Approved Constellation Persons, and the New Director shall not share such competitively sensitive Confidential Information with Constellation Software or such Approved Constellation Persons. Notwithstanding anything in this Agreement to the contrary, the New Director shall not utilize the Company's competitively sensitive Confidential Information in providing guidance to or acting on behalf of Constellation Software, its Affiliates or the Approved Constellation Persons in a manner that is detrimental to the Company. For purposes of this <u>Section</u> <u>3(d)</u>, "competitively sensitive Confidential Information" shall mean any non-public information the disclosure of which would reasonably be expected to (x) lessen competition or (y) violate applicable competition/anti-trust laws, including information concerning or reflecting (1) the Company's current or future prices, pricing plans or pricing strategies (including per-product margins, discounts, rebates and other price terms) of the Company's products and services or future product plans, (2) detailed sales by customer or customer contract terms, (3) detailed purchases by vendor or vendor contract terms, (4) detailed individual employee compensation and benefits, (5) material non-public information on trademarks, patents, trade secrets, and research and development, (6) the Company's strategy or business plans to compete with any Scheduled Entity, or (7) the Company's strategy or potential strategy with respect to any contemplated transaction, collaboration or investment involving any Scheduled Entity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) The Constellation Parties agree that the Board or any committee thereof, for the purposes of fulfilling the discharge of its fiduciary duties upon the advice of its legal counsel, may, upon the advice of its legal counsel, in its sole discretion, recuse the New Director from any Board or committee meeting (or applicable portion thereof) at which the Board or any such committee is evaluating and/or taking action with respect to (A) the exercise of any of the Company's rights or enforcement of any of the obligations under this Agreement, (B) any transaction or investment with, by or proposed by (i) the Constellation Parties, their Affiliates or Associates involving the Company or (ii) any Scheduled Entity, or (C) any other business activities, in each case, that the Company determines upon the advice of its legal counsel, would create a conflict of interest for the New Director. The Board or such committee, as applicable, may withhold from the New Director any material distributed to the directors solely to the extent it directly relates to the subject matter giving rise to that recusal under clauses (A), (B) or (C) above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Constellation Software shall provide the Company with written notice within five Business Days of the date on which any Constellation Party or any Affiliate thereof enters into a Competitive Transaction. The Company agrees that is shall, and shall cause its Representatives to, keep such information strictly confidential unless and until such time as it is publicly disclosed by any Constellation Party or Affiliate thereof.

Notwithstanding anything to the contrary contained in this Agreement, the Company shall be permitted to cause the New Director to withhold sharing any Confidential Information with Constellation Software or the Approved Constellation Persons, and the New Director shall not share such Confidential Information, as is reasonably determined by the Company upon the advice of legal counsel to be necessary to protect the Company's attorney-client or other legal and professional privileges.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. <u>Severability</u>. If at any time subsequent to the Effective Date, any provision of this Agreement is held by any court of competent jurisdiction to be illegal, void or unenforceable, such provision will be of no force and effect, but the illegality or unenforceability of such provision will have no effect upon the legality or enforceability of any other provision of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15. <u>No Waiver</u>. No failure or delay by any party in exercising any right or remedy hereunder will operate as a waiver thereof, nor will any single or partial waiver thereof preclude any other or further exercise thereof or the exercise of any other right or remedy hereunder. The failure of a party to insist upon strict adherence to any term of this Agreement on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement.
