FOR IMMEDIATE RELEASE

RECOMMENDED CASH OFFER

by

ICHOR MANAGEMENT LIMITED

(a newly incorporated company controlled by funds managed by ARCHIMED SAS)

for

INSTEM PLC

Results of Court Meeting and General Meeting

On 30 August 2023, the board of directors of Ichor Management Limited ("Bidco"), a newly incorporated company controlled by funds managed by ARCHIMED SAS, and the board of directors of Instem plc ("Instem") announced that they had reached agreement on the terms of a recommended cash offer by Bidco for the entire issued and to be issued share capital of Instem (the "Acquisition"). The Acquisition is being implemented by means of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006 (the "Scheme").

The scheme document in respect of the Acquisition was published and made available to Instem Shareholders on 25 September 2023 (the "Scheme Document"). Capitalised terms used but not otherwise defined in this announcement shall have the meaning given to them in the Scheme Document.

On 20 October 2023, Instem announced that it had adjourned the Court Meeting and General Meeting to 2 November 2023 to allow Instem Shareholders additional time to consider their votes, and set out an expected timetable of principal events in that announcement (the "Adjournment Announcement").

Results of the Court Meeting and the General Meeting

Instem is pleased to announce that at the Court Meeting and the General Meeting held earlier today:

·    the requisite majority of Scheme Shareholders voted (either in person or by proxy) in favour of the resolution to approve the Scheme at the Court Meeting; and

·    the requisite majority of Instem Shareholders voted (either in person or by proxy) in favour of the Special Resolution, including approving the amendment of the Instem Articles, at the General Meeting.

Details of the resolutions passed are set out in the notices of the Court Meeting and the General Meeting at Parts 9 and 10 (respectively) contained in the Scheme Document.

Voting results of the Court Meeting

The table below sets out the results of the poll at the Court Meeting held on 2 November 2023. Each Scheme Shareholder present was entitled to one vote per Scheme Share held at the Voting Record Time.

Voting results of the General Meeting

The table below sets out the results of the poll at the General Meeting held on 2 November 2023. Each Instem Shareholder was entitled to one vote per Instem Share held at the Voting Record Time.

The total number of Instem Shares in issue at the Voting Record Time was 22,899,433. The Company does not hold any ordinary shares in treasury. Therefore, the total number of voting rights in Instem at the Voting Record Time was 22,899,433.

Acquisition Conditions

The outcome of the Court Meeting and General Meeting means that Conditions 2(a) and (b) (as set out in Part A of Part 3 of the Scheme Document) have been satisfied. The Scheme remains subject to certain other Conditions, including: (i) the Secretary of State confirming that no further action will be taken in relation to the Acquisition pursuant to the NSIA (as set out in Part 3, Part A, paragraph 3(a) of the Scheme Document); (ii) the satisfaction (or, where applicable, waiver) of the remaining general Conditions set out in Part 3 of the Scheme Document; (iii) the Court sanctioning the Scheme; and (iv) the Court Order being duly delivered to the Registrar of Companies.

Subject to the satisfaction of these Conditions, it is the current intention of the Company to seek the Court's sanction of the Scheme on 16 November 2023, at a hearing to be held in The Royal Courts of Justice and the Scheme is expected to become effective on 20 November 2023.

If all the Conditions have not been satisfied before 16 November 2023 the expected timetable of principal events is likely to change, and Instem will make a further announcement regarding the expected timetable for the implementation of the Scheme.

Expected Timetable of Principal Events

An updated expected timetable for the Acquisition is set out in Appendix I to this announcement. Instem will provide a further update should this timetable change. All times shown are to London times unless otherwise stated.

A further announcement will be made by Instem following satisfaction of the NSIA Condition and the satisfaction (or, where applicable, waiver) of the remaining general Conditions set out in Part 3 of the Scheme Document.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in 1 per cent. or more of any class of relevant securities of Instem 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) Instem 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 Instem 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 per cent. or more of any class of relevant securities of Instem or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of Instem 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) Instem and (ii) any securities exchange offeror, 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 Instem 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 Instem and by any offeror, and Dealing Disclosures must also be made by Instem, 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 Takeover 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.
