OFFER MADE BY EURONEXT N.V. (“OFFEROR” OR “EURONEXT”) FOR THE ORDINARY
REGISTERED SHARES OF HELLENIC EXCHANGES-ATHENS STOCK EXCHANGE S.A. (“ATHEX”)



TENDER OFFER REVISION

1. In accordance with Article 21, paragraph 2 of Law 3461/2006 as in force (the “Law”), Euronext
announces the following:

a) On 30 July 2025, (the “Date of the Tender Offer”) the Offeror submitted a voluntary tender offer
(the “Tender Offer”) to acquire all ordinary registered shares, each having a nominal value of €0.42
(each, a “ATHEX Share”) issued by ATHEX, which Euronext and any “persons acting in concert”
(as defined in article 2(e) of the Law) with Euronext, did not hold directly or indirectly as at the Date
of the Tender Offer.

b) On 3 October 2025, the Hellenic Capital Market Commission (the “HCMC”) approved the
information circular in connection with the Tender Offer (the “Information Circular”).

c) In the terms of the Tender Offer included in the Information Circular, Euronext had set as a
prerequisite for the completion of the Tender Offer that no later than the end of the Acceptance
Period, at least 38,759,500 ATHEX Shares, corresponding to at least 67% of ATHEX’s total voting
rights whose exercise is not subject to suspension, shall have been lawfully and validly tendered
to the Offeror (the “Minimum Number of Shares”). Euronext had stated that this prerequisite may
be amended in accordance with the provisions of the Law.

d) On 7 November 2025 (the “Date of the Revision”), Euronext submitted to the HCMC a request to
revise the Tender Offer. According to the revised terms of the Tender Offer, the minimum number
of shares that should have been lawfully and validly tendered to the Offeror for the Tender Offer to
complete shall be equal to 28,925,001 ATHEX Shares, corresponding to 50% plus one (1) ATHEX
Share of the total voting rights of ATHEX whose exercise is not subject to suspension (the
“Reduced Minimum Number of Shares”).

e) The above revision of the Tender Offer in relation to the Reduced Minimum Number of Shares
remains subject to approval by the HCMC in accordance with Article 21 of the Law.

f) The revision of the Tender Offer does not extend the acceptance period of the Tender Offer which
started on 6 October 2025 and ends on 17 November 2025, at the end of the business hours of
banks operating in Greece (the “Acceptance Period”).

2. Shareholders who have duly and validly accepted the Tender Offer in accordance with the acceptance
procedure described in the Information Circular shall be deemed to have also accepted the revised
terms of the Tender Offer.

3. This announcement does not substitute the full text of the Information Circular to which any interested
party should refer and read carefully in conjunction with the section hereof headed “TENDER OFFER
REVISION”.

4. Statement of the Advisor

Deutsche Bank AG is acting as advisor to Euronext in connection with the Tender Offer and has provided
the following statement in accordance with article 12 of the Law:


1
“The Tender Offer is an offer consisting exclusively of shares as consideration. For this reason, the
credibility of the Tender Offer primarily depends on the Offeror’s ability to issue and deliver the required
number of Consideration Shares to the Accepting Shareholders. Deutsche Bank AG has certified, as per
paragraph 4.10 of the Information Circular, that the Offeror has the necessary means to pay the relevant
clearance rights to ATHEXCSD, as set out in section 4.10 therein. Furthermore, the Offeror has taken all
the corporate actions required and possible to be adopted up to the date of the Information Circular under
the laws of The Netherlands in order to increase its share capital through contribution in kind and to issue
the Consideration Shares, as described in the Information Circular and subject to the publication the
Offeror’s Exemption Document enabling the issuance of the Consideration Shares (which has been
satisfied) and the validly executed private deed of issuance. In addition, the Offeror has taken all appropriate
measures in order to perform the additional actions expected to take place and outlined in sections 5.5 of
the Information Circular and has appointed the Tender Agent and the Offeror’s DSS Participant in order to
ensure the duly closing of the Tender Offer.

In light of the above, the Advisor considers the Tender Offer to be credible. The Offeror has taken all
appropriate measures to be able to issue and deliver the Consideration Shares, as described above, and
to complete the Tender Offer in accordance with the terms and conditions set forth in the Information
Circular, subject, however, to the revision to section 4.2 (Prerequisite and Conditions of the Tender Offer)
described herein and to the occurrence of a force majeure event. In the event of force majeure, the relevant
provisions of the Greek Civil Code on the failure to perform obligations without fault shall apply.

Nonetheless, the Advisor does not provide any guarantee (within the meaning of Article 847 of the Greek
Civil Code) for the fulfilment by the Offeror of the obligation to offer the Consideration Shares or any
monetary and other obligations undertaken by the Offeror in the context of the Tender Offer nor does it bear
any liability within the meaning of article 729 of the Greek Civil Code.”

IMPORTANT NOTICES

General

The Tender Offer described herein is addressed to holders of ATHEX Shares and only to persons to whom
it may be lawfully addressed. The Tender Offer will be made in the territory of the Hellenic Republic. The
making of the Tender Offer to specific persons who are residents in or nationals or citizens of jurisdictions
outside the Hellenic Republic or to custodians, nominees or trustees of such persons (the “Excluded
Shareholders”) may be made only in accordance with the laws of the relevant jurisdiction. It is the
responsibility of the Excluded Shareholders and each person wishing to accept the Tender Offer to inform
themselves of and ensure compliance with the laws of their respective jurisdictions in relation to the Tender
Offer. If you have any doubts about your status, you should consult with your professional advisor in the
relevant jurisdiction.

The Tender Offer is not being made, directly or indirectly, by mail or by any means in or into any jurisdiction
within which, under its laws, rules and regulations, the submission, the making or the presentation of the
Tender Offer or the mailing or distribution of the Information Circular to be approved by the HCMC a
declaration of acceptance and any other document or material relevant thereto (together, the “Relevant
Documents”) is illegal or contravenes any applicable legislation, rule or regulation (together, the “Excluded
Territories”). Accordingly, copies of any such Relevant Documents and materials will not be, and must not
be, directly or indirectly, mailed, distributed or otherwise sent to anyone or from anyone in or into or from
any Excluded Territory.

No Offeror Shares have been offered or will be offered pursuant to the Tender Offer to the public in the
United Kingdom, except that the Offeror Shares may be offered to the public in the United Kingdom at any
time: (a) to any legal entity which is a qualified investor as defined under Article 2 of the UK Prospectus
Regulation; (b) to fewer than 150 natural or legal persons (other than qualified investors as defined under
Article 2 of the UK Prospectus Regulation); or (c) in any other circumstances falling within Section 86 of the


2
FSMA. Provided that no such offer of the Offeror Shares shall require Euronext or the Advisor to publish a
prospectus pursuant to Section 85 of the FSMA or supplement a prospectus pursuant to Article 23 of the
UK Prospectus Regulation. For the purposes of this provision, the expression an “offer to the public” in
relation to the Offeror Shares in the United Kingdom means the communication in any form and by any
means of sufficient information on the terms of the offer and any Offeror Shares to be offered so as to
enable an investor to decide to purchase or subscribe for any Offeror Shares and the expression “UK
Prospectus Regulation” means Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the
European Union (Withdrawal) Act 2018.

The Consideration Shares have not been and will not be registered under the U.S. Securities Act of 1933,
as amended (the “Securities Act”), or the securities laws of any state or other jurisdiction of the United
States and may not be offered, sold or delivered, directly or indirectly, in or into the United States absent
registration, or pursuant to an exemption from, or in a transaction not subject to, the registration
requirements of the Securities Act and in compliance with any applicable state and other securities laws of
the United States. This release does not constitute an offer to sell or solicitation of an offer to buy any of
the Consideration Shares in the United States. Euronext has no intention to register any part of the Tender
Offer in the United States or make a public offering of the Consideration Shares in the United States. Any
Consideration Shares offered in the United States will be offered only to (i) holders of the Company Shares
located outside of the United States and (ii) holders of Company Shares located within the United States
that are “Qualified Institutional Buyers” (as defined in Rule 144A under the Securities Act). Such holders of
Company Shares will be required to make such acknowledgements and representations to, and
agreements with, Euronext as Euronext may require establishing that they are entitled to receive
Consideration Shares pursuant to an exemption from or in a transaction not subject to the registration
requirements of the Securities Act. Accordingly, any holder of Company Shares located within the United
States who is not a Qualified Institutional Buyer or who does not make such acknowledgement and
representation to establish their entitlement to receive the Consideration Shares is ineligible to participate
in the Tender Offer, and any purported acceptance of the Tender Offer by such holder will be ineffective and
disregarded.

The Tender Offer is being made in the U.S. in reliance on the expected availability of the Tier II exemption

otherwise in accordance with the requirements of Greek law. The Tender Offer is not subject to Section
14(d)(1) of, or Regulation 14D promulgated under, the Exchange Act. The Company is not currently subject
to the periodic reporting requirements under the Exchange Act and is not required to, and does not, file any
reports with the SEC thereunder.

of the Tender Offer, Euronext may purchase, or arrange to purchase, whether directly or through any of its
affiliates, any broker or other financial institution acting as its agent or any affiliates of any broker or other
financial institution acting as its agent, shares of the Company as permitted by applicable law. The Offeror
Shares are issued to the Company's existing shareholders in Singapore without the intention of being
onsold there, and no documents issued by or on behalf of the Company may be used in any subsequent
sale by these shareholders. The Information Circular has not been and will not be lodged with or registered
as a prospectus under the Securities and Futures Act 2001 of Singapore with the Monetary Authority of
Singapore. Therefore, the Information Circular does not constitute an offer or invitation for the sale or
purchase of the Offeror Shares in Singapore, whether directly or indirectly, and shall not form the basis of
any contract for the issue or sale of the Consideration Shares in Singapore.
