RECOMMENDED ACQUISITION

of

Rotala PLC

by

Rotala Group Limited

("RGL")

a newly incorporated entity directly and indirectly owned and controlled by Simon Dunn, Robert Dunn, John Gunn, the spouses of Simon Dunn and Robert Dunn, and Wengen Pension Plan

Court Sanction of Scheme of Arrangement

On 20 November 2023, the Boards of Rotala and RGL announced that they had reached agreement on the terms of a recommended cash offer, pursuant to which RGL would acquire the entire issued and to be issued share capital of Rotala for 63.5 pence per share (the "Acquisition").

The Acquisition is to be effected by means of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006 (the "Scheme"), full details of which were sent to the shareholders of Rotala in the circular dated 11 December 2023 (the "Scheme Document").

On 4 January 2024, the Scheme was approved by the requisite majorities of Scheme Shareholders at the Court Meeting and the Special Resolutions in connection with the implementation of the Scheme were passed by the requisite majorities of Rotala Shareholders at the General Meeting.

Capitalised terms used and not defined in this announcement have the meanings given to them in the Scheme Document.

Sanction of Scheme

The boards of Rotala and RGL are pleased to announce that, earlier today, the High Court of Justice in England and Wales made an order sanctioning the Scheme under section 889 of the Companies Act.

The Scheme will become Effective upon the delivery of a copy of the Court Order to the Registrar of Companies, which is expected to occur on 17 January 2024.

Next steps and timetable

Rotala confirms that the last day of dealings in, and for registrations of transfers of, Rotala Shares will be 16 January 2024 and the Scheme Record Time will be 6.00 p.m. on 16 January 2024. Scheme Shareholders on Rotala's register of members at the Scheme Record Time will, upon the Scheme becoming Effective, be entitled to receive the consideration under the Scheme.

Trading on AIM in Rotala Shares will be suspended from 7:30 a.m. on 17 January 2024. The suspension is made pursuant to Rotala's application to the London Stock Exchange and is being effected as part of the Scheme.

It is expected that, subject to the Scheme becoming Effective on 17 January 2024, the cancellation of admission to trading on AIM of Rotala Shares will take effect at 7:00 a.m. on 18 January 2024.

A further announcement will be made when the Scheme becomes Effective.

Any decision in respect of, or other response to, the Acquisition should be made only on the basis of the information contained in the Scheme Document or any document by which the Acquisition is made.

To the extent permitted by applicable law, in accordance with normal UK practice, RGL or its nominees, or its brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase Rotala Shares, other than pursuant to the Acquisition, until the date on which the Scheme becomes Effective, lapses or is otherwise withdrawn. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases will be disclosed as required in the UK and will be reported to a regulatory information service and will be available on the London Stock Exchange website at www.londonstockexchange.com.

Overseas Shareholders

The availability of the Acquisition to Overseas Shareholders and the distribution of this announcement in, into or from jurisdictions other than the United Kingdom may be restricted by the laws of those jurisdictions and therefore persons into whose possession this announcement comes should inform themselves of, and observe, any such restrictions. Any person (including without limitation, nominees, trustees and custodians) who would, or otherwise intends to, forward this announcement, the Scheme Document or any accompanying document to any jurisdiction outside the United Kingdom should refrain from doing so and seek appropriate professional advice before taking any action. If any Overseas Shareholder remains in any doubt, it should consult an appropriate independent professional adviser in its relevant jurisdiction without delay. In particular, the ability of persons who are not resident in the United Kingdom to vote their Rotala Shares at the Court Meeting or the General Meeting or to execute and deliver Forms of Proxy appointing another to vote their Rotala Shares in respect of the Court Meeting or the General Meeting on their behalf, may be affected by the laws of the relevant jurisdiction in which they are located.

Failure to comply with any such restrictions may constitute a violation of the securities laws of any such jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility or liability for the violation of such restrictions by any person. This announcement has been prepared for the purposes of complying with the law of England and Wales and the Takeover 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 of England and Wales.

Additional Information for US Investors

The Acquisition is being made to acquire the securities of an English company by means of a scheme of arrangement provided for under the law of England and Wales. A transaction effected by means of a scheme of arrangement is not subject to the tender offer or proxy solicitation rules under the US Exchange Act of 1934 (the "US Exchange Act"). Accordingly, the Scheme will be subject to disclosure requirements and practices applicable in the United Kingdom to schemes of arrangement, which are different from the disclosure requirements of the US tender offer and proxy solicitation rules. The financial information included in this announcement and the Scheme documentation has been or will have been prepared in accordance with International Financial Reporting Standards and thus may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with US GAAP. US GAAP differs in certain significant respects from the International Financial Reporting Standards. None of the financial information in this announcement or the Scheme documentation has been audited in accordance with auditing standards generally accepted in the US or the auditing standards of the Public Company Accounting Oversight Board (United States). If RGL were to elect to implement the Acquisition by means of a Takeover Offer and determines to extend such Takeover Offer into the US, such Takeover Offer would be made in compliance with applicable US laws and regulations, including the US Exchange Act and Regulation 14E thereunder. Such a Takeover Offer would be made in the United States by RGL and no one else.

The receipt of cash pursuant to the Acquisition by a US holder as consideration for the transfer of its Rotala Shares pursuant to the Scheme will likely be a taxable transaction for US federal income tax purposes and under applicable US state and local, as well as foreign and other, tax laws. Each Rotala Shareholder is urged to consult his legal, tax and financial advisers immediately regarding the tax consequences of the Acquisition applicable to him/her, including under applicable US state and local, as well as foreign and other, tax laws.

It may be difficult for US holders to enforce their rights and claims arising out of the US federal securities laws in connection with the Acquisition, since RGL and Rotala are located in countries other than the United States, and some or all of their officers and directors may be residents of countries other than the United States. US holders may not be able to sue a non-US company or its officers or directors in a non-US court for violations of US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court's judgement.

In the event that the Acquisition is implemented by way of Takeover Offer, in compliance with applicable UK laws, RGL, its dealer manager (and their advisors or affiliates), or its nominees, or its brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase, shares or other securities of Rotala other than pursuant to such Takeover Offer during the period in which such Takeover Offer would remain open for acceptance. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases or arrangements to purchase will be disclosed as required in the United Kingdom, will be reported to a Regulatory Information Service and will be available on the London Stock Exchange website at www.londonstockexchange.com.

Neither the Acquisition nor this announcement have been approved or disapproved by the US Securities and Exchange Commission, any state securities commission in the United States or any other US regulatory authority, nor have such authorities approved or disapproved or passed judgement upon the fairness or the merits of the Acquisition, or determined if the information contained in this announcement is adequate, accurate or complete. Any representation to the contrary is a criminal offence in the United States.

Disclosure Requirements of the Takeover Code

Under Rule 8.3(a) of the Takeover Code, any person who is interested in 1 per cent. 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 p.m. (London time) on the 10th Business Day following the commencement of the offer period and, if appropriate, by no later than 3:30 p.m. (London time) on the 10th 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 Takeover Code, any person who is, or becomes, interested in 1 per cent. 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 p.m. (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 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.
