Sabre Corporation Adopts Limited-Duration Shareholder Rights Plan

Board acted in response to substantial accumulation of stock by Constellation Software

SOUTHLAKE, Texas, March 1, 2026 /PRNewswire/ — Sabre Corporation (“Sabre” or the “Company”) (NASDAQ: SABR) today announced that its Board of Directors (the “Board”) has approved the adoption of a limited-duration shareholder rights plan (“Rights Plan”) to protect the interests of Sabre and its shareholders. The Rights Plan is effective immediately and expires in one year.  

The Board, in consultation with its independent advisors, adopted the Rights Plan in response to the substantial accumulation of shares of Sabre’s common stock by Constellation Software Inc. (“Constellation”) (TSX: CSU). In deciding to adopt the Rights Plan, the Board considered, among other things, that:

• Between April 2025 and November 2025, Constellation accumulated a 9.7% economic position in Sabre, comprising 4.7% beneficial ownership of common stock and a further 5% via derivative instruments, and privately informed Sabre of its ownership stake for the first time in early January 2026;
• Constellation is a serial acquirer of software companies that build verticals, and one of its operating groups, Vela Software, has in recent years acquired several travel technology companies;
• In connection with its outreach in early January 2026, Constellation requested a board seat for two of its executives, and during the course of discussions with the Company, delivered a nomination notice under the Company’s bylaws on January 23, 2026;
• Constellation previously suggested to Sabre its desire that its investment in Sabre be similar to its investment in Asseco Poland S.A., where it currently holds a 24.8% position;
• Sabre engaged in constructive discussions with Constellation and began negotiating a strategic governance agreement to appoint the CEO of Constellation’s Vela Software division to the Board and enable continued collaboration between the two parties with the goal of driving long-term growth and value creation;
• On February 26, 2026, despite the parties nearing the finish line on the agreement, Constellation abruptly and without explanation broke off several weeks of constructive negotiations and stated that its intentions “would appear clear with the benefit of time;”
• Sabre made multiple attempts to reengage Constellation on February 26 and February 27, 2026, that remain unanswered, and on February 28, 2026, Constellation withdrew the formal nomination of its second candidate (not the candidate who the parties had been contemplating would join the Board in connection with the proposed strategic governance agreement) without providing any explanation or otherwise responding to Sabre’s requests to reengage; and
• During the week of February 23 through February 27, 2026, the Company observed unusually high trading volume in its stock.

The Rights Plan was not adopted in response to any proposal from Constellation or another party to acquire control of the Sabre and is not intended to deter offers or preclude the Board from considering offers that are fair and otherwise in the best interest of the shareholders. Subject to understanding the basis for Constellation’s changed posture, Sabre remains open to resuming discussions with Constellation regarding a negotiated agreement on acceptable terms.

The Rights Plan is intended to enable all shareholders to realize the long-term value of their investment in Sabre and ensure they receive fair and equal treatment in the event of any proposed takeover. The Rights Plan is also intended to reduce the likelihood that any person or group gains control of the Company through open-market accumulation or other tactics without paying an appropriate control premium or providing the Board sufficient time to make informed decisions that are in the best interests of Sabre and its shareholders.

About the Rights Plan

The Rights Plan is similar to shareholder rights plans adopted by other publicly traded companies. Pursuant to the Rights Plan, Sabre is issuing one right for each share of common stock as of the close of business on March 11, 2026. The rights will initially trade with Sabre common stock and will generally become exercisable only if any person (or any persons acting as a group) acquires 15% (or 20% for certain passive investors) or more of the outstanding common stock (the “triggering percentage”). The Rights Plan does not aggregate the ownership of shareholders “acting in concert” unless and until they have formed a group under applicable securities laws. If the rights become exercisable, all holders of rights (other than any triggering person) will be entitled to acquire shares of common stock at a 50% discount or Sabre may exchange each right held by such holders for one share of common stock. Under the Rights Plan, any person that currently owns more than the triggering percentage may continue to own its shares of common stock but may not acquire any additional shares without triggering the Rights Plan. The Rights Plan does not contain any dead-hand, slow-hand, no-hand or similar feature that limits the ability of a future board of directors to redeem the rights.

The Rights Plan has a one-year term, expiring on February 28, 2027. The Board may consider an earlier termination of the Rights Plan as circumstances warrant. Further details about the Rights Plan will be contained in a Form 8-K to be filed by Sabre with the SEC.
