RECOMMENDED ACQUISITION

of

Rotala PLC

("Rotala" or the "Company")

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

Results of the Court Meeting and the General Meeting

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"). Capitalised terms in this announcement, unless otherwise defined herein, have the same meanings as set out in the Scheme Document.

Results of the Court Meeting and the General Meeting

Rotala is pleased to announce that, at the Court Meeting and General Meeting (together the "Meetings") each held earlier today, the requisite majorities of Scheme Shareholders present and voting (and entitled to vote) either in person or by proxy voted to approve the Scheme at the Court Meeting and of Rotala Shareholders (either in person or by proxy) voted to pass the Special Resolutions in connection with the implementation of the Scheme at the General Meeting.

The resolutions were therefore duly passed. Full details of the resolutions are set out in the notices of the Meetings contained in Parts IX and X of the Scheme Document, respectively.

The total number of Rotala Shares in issue (excluding treasury shares) at the Voting Record Time was 31,021,784. Rotala holds 5,910,000 Ordinary Shares in treasury. Therefore, the total voting rights in Rotala at the Voting Record Time were 31,021,784.

Voting Results of the Court Meeting

The Court Meeting sought approval from the holders of the Scheme Shares (other than the holders of Non-Voting Scheme Shares) for the Scheme. Each Scheme Shareholder, present in person or by proxy (not being a holder of Non-Voting Scheme Shares), was entitled to vote one Scheme Share held at the Voting Record Time and voting was by way of a poll. The Scheme Shares are all the Ordinary Shares except for the 6,601,398 Excluded Shares registered in the name of or beneficially owned directly or indirectly by the RGL Shareholders and the Personal Investment Vehicles, and the 5,910,000 Ordinary Shares held in treasury. Therefore, there are 24,420,386 Scheme Shares currently in issue, of which 6,182,822 Non-Voting Scheme Shares could not be voted at the Court Meeting. In total, 18,237,564 Scheme Shares could be voted at the Court Meeting. The Non-Voting Scheme Shares, unlike the Excluded Shares, are Scheme Shares and will be acquired under the Scheme.

Accordingly, the Court Meeting resolution proposed at the Court Meeting was duly passed.

Details of the votes cast were as follows:

· Note that the percentages in the table above are rounded to the nearest two decimal places.

· Where a Scheme Shareholder has cast some of their votes "for" and some of their votes "against" the resolution, such Scheme Shareholder has been counted as having voted both "for" and "against" the resolution for the purposes of determining the number of Scheme Shareholders who voted as set out in column 2 above. In this instance, 2 Scheme Shareholders voted both "for" and "against" and are therefore counted twice when calculating percentages, however, only 49 Scheme Shareholders voted in total.

· The Excluded Shares comprise any Rotala Shares: (i) registered in the name of, or beneficially owned by, RGL or any other member of the Wider RGL Group or their respective nominees; (ii) registered in the name of, or beneficially owned by, any RGL Shareholder or Personal Investment Vehicle, or any of their respective nominees except for any Rotala Shares acquired after the Scheme Court Hearing pursuant to the exercise of options under the Rotala Share Scheme; and (iii) held in treasury by Rotala.

· The Non-Voting Scheme Shares are the Rotala Shares registered in the name of or beneficially owned directly or indirectly by the Concert Parties.

Voting Results of the General Meeting

The General Meeting sought approval for the Resolutions for the purpose of (i) giving effect to the Scheme and associated amendments to the articles of association of the Company; (ii) conditional on inter alia the cancellation of the Company's listing on AIM, of re-registering the Company as private company, with the name Rotala Limited; and (iii) of disapplying statutory pre-emption rights in connection with the sale or transfer out of treasury of up to 5,910,000 Ordinary Shares. Each Rotala Shareholder, present in person or by proxy, was entitled to vote one Rotala Share held at the Voting Record Time and voting was by way of a poll.

Accordingly, each of the Resolutions were duly passed by the requisite majority.

Details of the votes cast were as follows:

Special Resolution 1

Special Resolution 2

Special Resolution 3

· Note that the percentages in the tables above are rounded to the nearest two decimal places.

· Proxy appointments which gave discretion to the Chairman have been included in the vote "For" totals.

· A vote withheld is not a vote in law and is not counted in the calculation of the proportion of votes 'For' or 'Against' any of the Special Resolutions.

Next steps and timetable

The outcome of today's Meetings means that Conditions 2.1 and 2.2 (as set out in Part III of the Scheme Document) have been satisfied.

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.
