Amadeus IT Group share Buy-back Programme

The Board of Directors of Amadeus, at its meeting held on 14 December 2017, has agreed to undertake a Share Buy-back Programme (Buy-back Programme or Programme) in accordance with the authorisation granted by the Ordinary General Shareholders' Meeting held on 20 June 2013.

The Buy-back Programme will be carried out in accordance with the provisions of the Commission Delegated Regulation (EU) 2016/1052 of 8 of March (the Regulation), in order to reduce the share capital of the Company through the redemption of shares, subject to the prior agreement to be granted by the Ordinary General Shareholders'

Meeting to take place after the closing of each of the respective tranches of the Programme.

The maximum investment of the Buy-back Programme will be €1,000 million and under no circumstances shall the number of shares to be acquired under the Programme exceed 25,000,000 shares, representing 5.69% of the share capital of the Company, for redemption, and it will be carried out in the following manner:

Maximum Execution Period: 27 months (from 1st January 2018 to 31st March 2020), without considering potential suspension periods.

Execution of the Buy-back Programme: Two tranches

• - Tranch 1: Up to €500 million (non-cancellable), 15 months term (from 1st January 2018 to 31st March 2019), with a compulsory minimum purchase period of 9 months.

• - Tranch 2: Up to €500 million (cancellable if the circumstances so required, at Company's discretion), 12 months term (from 1st April 2019 to 31st March 2020).

Suspension: The Company will have the right to suspend the Tranche 2 of the Buy-back Programme if the circumstances so required, at Company's discretion. In case of suspension, the corresponding suspension period would be added to the Maximum Execution Period.

Compulsory suspension: The Buy-back Programme will be compulsory suspended on June 20, 2018 (expiration date of the authorization granted to the Board of Directors by the Ordinary General Shareholder's Meeting to acquire treasury shares), until the date of the new authorization to be granted by the Ordinary General Shareholder's Meeting to take place tentatively on June 21, 2018.

Compulsory cancellation: The Buy-back Programme will be automatically cancelled if the Ordinary General Shareholder's Meeting to take place tentatively on June 21, 2018, does not pass a resolution granting new authorization to the Board of Directors to acquire treasury shares, replacing the current one dated June 20, 2013.

Notwithstanding the above, Amadeus reserves the right to terminate the Buy-back Programme if, prior to its expiration date, Amadeus has acquired thereunder shares for a purchase price that reached the maximum investment price or has acquired the maximum number of shares under the Programme.

The shares will be purchased at the market price in accordance with the price and volume requirements set forth in Article 3 of the Regulation. In particular, with respect to the price, Amadeus will not purchase shares at a price higher of the price of the last independent trade and the highest current independent bid on the trading venue where the purchase is carried out. With respect to the trading volume, the Company will not purchase on any trading day more than 25% of the average daily volume of the shares of Amadeus on the trading venue on which the purchase is carried out. This limit applies to the entire Buy-back Programme.

An irrevocable mandate to purchase shares will be granted to the financial entity acting as agent on behalf of the Company for the execution of the Buy-back Programme and it will make its purchasing decisions independently and without influence from Amadeus.

The approval, modification or extension, if so required, interruption and termination of the Buy-back Programme as well as purchase of shares made thereunder will be duly notified to the Spanish Stock Exchange Commission (CNMV) through the corresponding relevant information announcement in accordance with the provisions of the Regulation and recommendations of the CNMV regarding discretionary transaction information of treasury stock of July 18, 2013.
