Transaction in Own Shares.

Completion of First Tranche and Commencement of Second Tranche of Share Buyback Programme

INTERNATIONAL CONSOLIDATED AIRLINES GROUP, S.A. ("IAG" or the "Company") confirms that following the last acquisition of shares on 29 May 2025, the first tranche of €500 million of its share buyback programme of up to €1,000 million (the "Programme"), which the Company announced on 28 February 2025, has now been completed in accordance with its terms. To date, under the Programme, the Company has acquired a total of 148,068,554 ordinary shares in the aggregate, representing approximately 2.98 per cent. of the Company's share capital.

IAG today also announces the launch of the second tranche of €500 million (the "Second Tranche") of the Programme.

The purpose of the Programme is the reduction of IAG's share capital (subject to the approval of such reduction by its Shareholders' Meeting) and the Programme has been and will continue to be carried out in accordance with the authorisation granted by the Annual General Shareholders' Meeting held on 26 June 2024 and, if granted, by the Annual General Shareholders' Meeting which is scheduled to be held on 19 June 2025.

As previously announced on 28 February 2025, Goldman Sachs Bank Europe SE ("GS") and Morgan Stanley Europe SE ("MS") have been engaged to implement the Programme, in sequential portions (so that each bank will implement alternate portions of each tranche of the Programme). GS and MS (and/or its delegates) will make the share purchases on the Company's behalf (acting as riskless principal and not as agent) and make all trading decisions independently of, and uninfluenced by, the Company, subject to certain parameters agreed between the Company and each of GS and MS prior to the commencement of the Programme.

Also, as announced on 28 February 2025, Qatar Airways Group Q.C.S.C. ("Qatar Airways") has agreed to participate in the Programme on a pro rata basis so as to maintain its current aggregate stake in IAG (25.1434% of its share capital). For such purpose, arrangements have been entered into between Qatar Airways and each of GS and MS pursuant to which Qatar Airways has agreed not to sell IAG shares in the market during the Programme but instead to sell to GS and MS, as applicable, on each trading day during the Programme (for on-sale to IAG) a number of shares proportionate to the number of shares bought by GS or MS, as applicable, in the market on each trading day, and at a price per share equal to the volume weighted average price at which GS or MS, as applicable, has purchased such shares on the market on such trading day.

Therefore, the Second Tranche of the Programme will be executed through purchases of shares from market participants and purchases of shares from Qatar Airways on the terms set forth above, in an aggregate amount of up to €500 million (€374 million for purchases from market participants and €126 million for purchases from Qatar Airways).

The Second Tranche of the Programme will start on 2 June 2025 and is expected to end no later than 28 November 2025, unless terminated by the Company, GS or MS, as applicable, in certain circumstances.

The Second Tranche of the Programme will also be carried out in accordance with the provisions of the Market Abuse Regulation (EU) 596/2014 and Commission Delegated Regulation (EU) 2016/1052 (including as incorporated into UK law) regarding the exemption for buyback programmes, and will have the following characteristics:

a)    Regulated market: the shares will be purchased on both the London Stock Exchange and the Spanish Stock Exchanges (each an "Exchange").

b)    Maximum pecuniary amount allocated to the Second Tranche: €500,000,000, with up to €374,283,000 allocated to purchases of shares from market participants.

c)    Maximum number of shares to be acquired pursuant to the Second Tranche: up to 181,931,446  ordinary shares, which represent 3.66 per cent. of the Company's share capital as of today's date (30 May 2025).

d)    Consideration per share: the shares will be purchased at a price of no more than the lower of: (i) the higher of the price of the last independent trade and the highest then current independent purchase bid on the Exchange where the purchase is carried out, and (ii) 105 per cent. of the average market value of the shares for the five business days prior to the day the purchase is made.

e)    Maximum volume per trading session (including share purchases from both market participants and from Qatar Airways): no more than 25 per cent. of the average daily volume of the shares traded on the Exchange in the 20 trading days immediately preceding the date of purchase.

The shares purchased under the Programme will be held in treasury pending approval to cancel such shares being granted by IAG's Shareholders' Meeting.
