RECOMMENDED CASH OFFER

for

Aquis Exchange plc ("Aquis")

by

SIX Exchange Group AG ("SIX")

PUBLICATION OF SCHEME DOCUMENT

On 11 November 2024, the boards of directors of Aquis and SIX announced that they had reached agreement on the terms of a recommended cash offer to be made by SIX for the entire issued and to be issued share capital of Aquis (the "Acquisition"), to be implemented by way of a court-sanctioned scheme of arrangement under Part 26 of the Companies Act (the "Scheme").

Publication of the Scheme Document

Aquis announces that a circular in relation to the Scheme (the "Scheme Document") setting out, among other things, a letter from the Chair of Aquis, an explanatory statement pursuant to section 897 of the Companies Act, the full terms and conditions of the Scheme, an expected timetable of principal events, notices of the Court Meeting and the General Meeting and details of the actions to be taken by Aquis Shareholders, has been published today on Aquis' website at https://www.aquis.eu/investors/offer-documentation and on SIX's website at www.six-group.com/recommended-offer-aquis.

Hard copies of the Scheme Document (or, depending on Aquis Shareholders' communication preferences, a letter or email giving details of the website where the Scheme Document may be accessed) and Forms of Proxy for the Court Meeting and the General Meeting are being sent to Aquis Shareholders today.

Capitalised terms used in this announcement shall, unless otherwise defined, have the same meanings as set out in the Scheme Document. All references to times in this announcement are to London, United Kingdom times unless stated otherwise.

Action required

As further detailed in the Scheme Document, in order to become Effective, the Scheme will require, among other things, that the requisite majority of: (i) Scheme Shareholders vote in favour of the Scheme at the Court Meeting; and (ii) Aquis Shareholders vote in favour of the Scheme Resolution at the General Meeting. In addition, Aquis Shareholders will be asked to approve the Re-Registration Resolution at the General Meeting. However, the Re-Registration Resolution is not a condition to the Acquisition.

The approval required at the Court Meeting for approval of the Scheme is a majority in number of the Scheme Shareholders who are present and vote, whether in person or by proxy, at the Court Meeting and who represent 75 per cent. or more in value of the Scheme Shares voted by those Scheme Shareholders. The approval required at the General Meeting for the Special Resolutions to be passed is at least 75 per cent. of the votes cast on such resolutions (in person or by proxy).

Notices convening the Court Meeting and the General Meeting to be held at 63 Queen Victoria Street, London, England, EC4N 4UA on 20 December 2024 at 11:00 a.m. (U.K. time) and 11:15 a.m. (U.K. time) (or as soon thereafter as the Court Meeting concludes or is adjourned), respectively, are set out in the Scheme Document.

Any changes to the arrangements for the Court Meeting and the General Meeting will be communicated to Aquis Shareholders before the relevant Meeting, through Aquis' website https://www.aquis.eu/investors/offer-documentation and by announcement through a Regulatory Information Service.

Scheme Shareholders and Aquis Shareholders are asked to submit proxy appointments and instructions for the Court Meeting and the General Meeting as soon as possible and in any event so that the proxy appointment and instructions are received by Equiniti no later than 48 hours prior to the Court Meeting or the General Meeting as applicable (excluding any part of such 48 hour period falling on a day that is not a Business Day) or, in the case of any adjournment, not later than 48 hours (excluding any part of such 48 hour period that is not Business Day) before the time fixed for the adjourned Meeting.

It is important that, for the Court Meeting in particular, as many votes as possible are cast so that the Court may be satisfied that there is a fair representation of opinion of Scheme Shareholders.

Timetable

The Scheme Document contains an expected timetable of principal events in relation to the Scheme, which is also set out in the Appendix to this announcement. The Scheme remains conditional on the approval of the requisite majority of Scheme Shareholders at the Court Meeting and the requisite majority of Aquis Shareholders at the General Meeting. The Scheme is also subject to the satisfaction (or, where applicable, waiver) of the other Conditions (including regulatory and antitrust conditions and the sanction of the Court) and further terms, as described more fully in the Scheme Document.

The Scheme is expected to become Effective during Q2 2025. Aquis will make further announcements through a Regulatory Information Service, with such announcements also being made available on Aquis' website at https://www.aquis.eu/investors/offer-documentation and on SIX's website at www.six-group.com/recommended-offer-aquis.

An update to the expected timetable is expected to be announced following receipt of the relevant regulatory approvals upon which the Acquisition is conditional.

Recommendation

The Aquis Directors, who have been so advised by Evercore as to the financial terms of the Acquisition, consider the terms of the Acquisition to be fair and reasonable. In providing advice to the Aquis Directors, Evercore have taken into account the commercial assessments of the Aquis Directors. Evercore is providing independent financial advice to the Aquis Directors for the purposes of Rule 3 of the Takeover Code.

The Aquis Directors believe that the terms of the Acquisition (including the Scheme) are in the best interests of Aquis Shareholders as a whole. Accordingly, the Aquis Directors unanimously recommend that Scheme Shareholders vote in favour of the Scheme at the Court Meeting and that Aquis Shareholders vote in favour of the Special Resolution to be proposed at the General Meeting, as those Aquis Directors who hold Aquis Shares have irrevocably agreed to do in respect of their own beneficial holdings.

Aquis Shareholders should carefully read the Scheme Document in its entirety before making a decision with respect to the Scheme.

The Scheme Document includes an update on Aquis' current trading which is summarised as follows. Aquis' underlying trading performance since announcing its interim results for the six months ended 30 June 2024 on 12 September 2024 has been in line with Board expectations. Achieving the Board's expectations for full year performance to 31 December 2024 is predicated on a continuation of underlying trading performance and the renewal of a material contract in Aquis' technology division where discussions are ongoing.

A copy of the Scheme Document will be submitted to the National Storage Mechanism and will be available for inspection at https://data.fca.org.uk/#/nsm/nationalstoragemechanism.

If the Scheme is sanctioned as outlined above, it is expected that the last day of dealings in, and registration of transfers of, Aquis Shares on AIM and on the Aquis Stock Exchange will be the Business Day immediately prior to the Effective Date. It is intended that, subject to the Scheme becoming effective, applications will be made to the London Stock Exchange and to the Aquis Stock Exchange for the cancellation of admission to trading of the Aquis Shares on AIM and on the Aquis Stock Exchange respectively, and steps will be taken to re-register Aquis as a private limited company.

Overseas Shareholders

The availability of the Scheme and the Acquisition to Overseas Shareholders may be affected by the laws of the relevant jurisdictions in which they are resident. Overseas Shareholders should inform themselves of, and observe, any applicable requirements. It is the responsibility of all Overseas Shareholders to satisfy themselves as to the full compliance of the laws of the relevant jurisdiction in connection therewith, including the obtaining of any governmental, exchange control or other consents which may be required, or the compliance with other necessary formalities which are required to be observed and the payment of any issue, transfer or other taxes due in such jurisdiction.

The release, publication or distribution of this announcement in jurisdictions other than the United Kingdom may be restricted by law and therefore any persons who are subject to the laws of any jurisdiction other than the United Kingdom should inform themselves about and observe any applicable requirements.

In particular, the ability of persons who are not resident in the United Kingdom to vote their Aquis Shares with respect to the Scheme at the Court Meeting, or to execute and deliver Forms of Proxy appointing another to vote at the Court Meeting on their behalf, may be affected by the laws of the relevant jurisdictions in which they are located. This announcement and accompanying documents have been prepared for the purpose of complying with English law, the AIM Rules, the Aquis Rules and the Code and the information disclosed may not be the same as that which would have been disclosed if this announcement had been prepared in accordance with the laws of jurisdictions outside the United Kingdom.

Copies of this announcement and any formal documentation relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in or into or from any Restricted Jurisdiction and persons receiving such documents (including custodians, nominees and trustees) must not mail or otherwise forward, distribute or send it in or into or from any Restricted Jurisdiction.

If the Acquisition is implemented by way of an Offer (unless otherwise permitted by applicable law and regulation), the Offer may not be made directly or indirectly, in or into, or by the use of mails or any means or instrumentality (including, but not limited to, facsimile, e-mail or other electronic transmission, telex or telephone) of interstate or foreign commerce of, or of any facility of a national, state or other securities exchange of any Restricted Jurisdiction and the Offer may not be capable of acceptance by any such use, means, instrumentality or facilities.

Notice to U.S. investors in Aquis

The Acquisition relates to shares in a U.K. company and is proposed to be made by means of a scheme of arrangement under English company law. U.S. holders of Aquis Shares should note that the Scheme relates to the shares of a U.K. company that are not registered under the U.S. Exchange Act and will be governed by English law. Neither the proxy solicitation rules nor the tender offer rules under the U.S. Exchange Act will apply to the Scheme. Moreover, the Scheme will be subject to the disclosure requirement and practices applicable in the U.K. to schemes of arrangement, which differ from the disclosure requirements of the U.S. proxy solicitation rules and tender offer rules. Financial information included in this announcement and accompanying documents have been prepared in accordance with accounting standards applicable in the U.K. that may not be comparable to financial statements of U.S. companies. If SIX exercises its right to implement the acquisition of the Aquis Shares by way of an Offer, such Offer will be made in compliance with applicable U.S. securities laws and regulations to the extent applicable.

The receipt of cash pursuant to the Acquisition by a U.S. holder of Aquis Shares as consideration for the transfer of its Aquis Shares pursuant to the Scheme may be a taxable transaction for United States federal income tax purposes and under applicable United States state and local, as well as foreign and other, tax laws. Each Aquis Shareholder is urged to consult with independent professional advisers immediately regarding the tax consequences of the Acquisition applicable to it.

It may be difficult for U.S. holders of Aquis Shares to enforce their rights and any claim arising out of the U.S. federal laws, since SIX and Aquis are located in non-U.S. jurisdictions, and some or all of their officers and directors may be residents of a non-U.S. jurisdiction. U.S. holders of Aquis Shares may not be able to sue a non-U.S. company or its officers or directors in a non-U.S. court for violations of the U.S. securities laws. Further, it may be difficult to compel a non-U.S. company and its affiliates to subject themselves to a U.S. court's judgement.

Neither the United States Securities and Exchange Commission nor any U.S. state securities commission has approved or disapproved the Acquisition, passed upon the merits or fairness of the Acquisition or passed any opinion upon the accuracy, adequacy or completeness of this announcement. Any representation to the contrary is a criminal offence in the United States.

Cautionary note regarding forward-looking statements

This announcement (including information incorporated by reference in this announcement), oral statements made regarding the Acquisition, and other information published by Aquis, any member of the Aquis Group, SIX or the SIX Group contain statements which are, or may be deemed to be, "forward-looking statements". Such forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and on numerous assumptions regarding the business strategies and the environment in which Aquis, any member of the Aquis Group, SIX or the SIX Group shall operate in the future and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by those statements.

Forward-looking statements include, among other things, statements concerning the potential exposure of Aquis and the Aquis Group and SIX and the SIX Group to market risks, statements as to accretion and statements expressing management's expectations, beliefs, estimates, forecasts, projections and assumptions, including as to future potential cost savings, synergies, earnings, cash flow, return on capital employed, production and prospects. These forward-looking statements are identified by their use of terms and phrases such as "aims", "anticipate", "believe", "could", "estimate", "expect", "goals", "hopes", "intend", "may", "objectives", "outlook", "plan", "probably", "project", "risks", "seek", "should", "target", "will", "would" and similar terms and phrases.

By their very nature, forward-looking statements involve risks and uncertainties. There are a number of factors that could affect the future operations of SIX and the SIX Group and Aquis and the Aquis Group and could cause those results to differ materially from those expressed in the forward-looking statements included in this announcement. Neither Aquis, the Aquis Group, SIX nor the SIX Group, nor any of their respective associates or directors, officers or advisers, provide any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this announcement will actually occur. Given these risks and uncertainties, potential investors are cautioned not to place any reliance on these forward-looking statements.

The forward-looking statements contained in this announcement and accompanying documents speak only as at the date of this announcement and are not intended to give any assurance as to future results. Other than in accordance with their legal or regulatory obligations, neither Aquis, the Aquis Group, SIX nor the SIX Group is under any obligation, and each such person expressly disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Disclosure requirements of the Takeover Code

Under Rule 8.3(a) of the Code, any person who is interested in 1% or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the offer period and, if later, following the announcement in which any securities exchange offeror is first identified. An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 pm (London time) on the 10th business day following the commencement of the offer period and, if appropriate, by no later than 3.30 pm (London time) on the tenth business day following the announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1% or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s), save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 pm (London time) on the business day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Takeover Panel's website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the offer period commenced and when any offeror was first identified. You should contact the Panel's Market Surveillance Unit on +44 (0) 20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.
