Notice of AGM & Proposed Rule 9 Waiver

Primorus Investments PLC

("Primorus" or the "Company")

Notice of AGM & Proposed Rule 9 Waiver

Primorus Investments plc (AIM: PRIM) announces that a circular to Shareholders giving Notice of the Annual General Meeting ("AGM") with accompanying Form of Proxy will be sent to Shareholders shortly.  The circular includes a letter from the Chairman of the Company setting out details about the Resolutions being proposed at the AGM.

The AGM will be held on 15 July 2026 at 9:00 a.m. at Sackville House, 55 Buckhurst Avenue, Sevenoaks, Kent TN13 1LZ.

Proposed Share Buyback and Rule 9 Waiver

The Company has, since its annual general meeting held in June 2022, been granted by Shareholders the authority to make market purchases of its own shares, subject to specific conditions relating to price and volume, in common with many other UK public companies. The buyback authority was obtained to allow the Company to purchase Ordinary Shares through the London Stock Exchange if there was limited liquidity in the market, and if the Directors considered that it was in the best interests of the Company and Shareholders as a whole. Any purchased Ordinary Shares would be held as treasury shares.

The Company sought Shareholder approval at the 2025 AGM to make market purchases of up to 55,932,387 Ordinary Shares. Since the 2025 AGM, the Company has bought back an aggregate 15,330,968 Ordinary Shares, being the Treasury Shares.

At the 2026 AGM, to be held on 15 July 2026, the Company will seek Shareholder approval of a new buyback authority for the Company to make on market purchases of up to 29.04 per cent. of its Existing Issued Share Capital implemented by way of share buyback (the "Share Buyback Authority"). Accordingly, the AGM Notice convening the 2026 AGM, which is set out on pages 19 and 20 of the Circular, sets out a resolution to be proposed to seek Shareholder approval of the Share Buyback Authority ("Share Buyback Resolution").

The Company has agreed with the Panel that the following persons are acting in concert in relation to the Company: Rupert Labrum and Hedley Clark, being the Executive Chairman and a Non-Executive Director respectively. Accordingly they (together with their close relatives and the related trusts of any of them) make up a concert party as defined by the Takeover Code (the "Concert Party"). As at the date of the Notice of AGM, the Concert Party has a combined interest in 41,780,673 Ordinary Shares, representing approximately 29.88 per cent. of the Existing Issued Share Capital and approximately 33.56 per cent. of the Voting Share Capital.

Any purchases by the Company of its own Ordinary Shares will reduce the Voting Share Capital and may thereby increase the Concert Party's holding of the resultant Voting Share Capital.

Under Rule 9 of the Takeover Code, when any person acquires an interest in shares which (taken together with shares in which the person or any person acting in concert with that person is interested) carry 30 per cent. or more of the voting rights of a company, such person shall extend offers to the holders of the other shares in company. Under Rule 37.1 of the Takeover Code, when a company redeems or purchases its own voting shares, any resulting increase in the percentage of shares carrying voting rights in which a person or group of persons acting in concert is interested will be treated as an acquisition for the purpose of Rule 9. Subject to prior consultation, the Panel will normally waive any resulting obligation to make an offer under Rule 9 if there is a vote of independent shareholders.

The Panel has agreed to waive the obligation to make an offer that would otherwise arise under Rule 9 as a result of the Share Buyback Programme, subject to the approval of the Independent Shareholders. Accordingly, the Rule 9 Waiver Resolution is being proposed at the Annual General Meeting of the Company and will be taken on a poll. The members of the Concert Party will not be entitled to vote on the Rule 9 Waiver Resolution.

The Chairman's letter is set out in full below.

A copy of the Company's AGM Notice will shortly be available on the Company's website www.primorusinvestments.com.  Defined terms used in this announcement are the same as those defined in the Circular unless the context requires otherwise.

Dear Shareholder

1.       Annual General Meeting 2026

I have pleasure in enclosing the Notice of the 2026 Annual General Meeting ("AGM Notice" or "2026 AGM", as the context requires) of Primorus Investments plc (the "Company" or "Primorus") which will be held at 9:00 a.m. on 15 July 2026 at Sackville House, 55 Buckhurst Avenue, Sevenoaks, Kent TN13 1LZ.

Full details of the meeting and the resolutions to be put to Shareholders are set out in the enclosed AGM Notice (the "Resolutions") on pages 19 and 20 of this document. An explanation of the business to be considered and voted on at the 2026 AGM is set out in section 2 (Resolutions) below.

2.       Resolutions

In addition to the routine business customarily undertaken at an annual general meeting, we are asking Shareholders to consider and, if thought fit, approve a specific item of special business at the 2026 AGM, namely the Rule 9 Waiver. Shareholders may recall that a similar resolution was proposed at the 2025 AGM.

The purpose of this document is to provide you with information about the Resolutions, and to explain why the Board considers the Resolutions to be in the best interests of the Company and its Shareholders as a whole.

Regarding the Rule 9 Waiver Resolution, Shareholders should note that, unless the Rule 9 Waiver Resolution is approved at the 2026 AGM, the Rule 9 Waiver will not become effective. The waiver granted at the 2025 AGM will expire at the end of the 2026 AGM.

3.       Rule 9 Waiver

As at the Latest Practicable Date, the Company had: (i) available cash of approximately £31,576 and no debt; and (ii) 139,830,968 Ordinary Shares in issue and admitted to trading on AIM and holds 15,330,968 Ordinary Shares in treasury (being the Treasury Shares). The number of Ordinary Shares in issue (excluding Treasury Shares), and the figure to be used as the denominator for calculations of interests in the Company's voting rights, is 124,500,000.

The Company has, since its annual general meeting held in June 2022, been granted by Shareholders the authority to make market purchases of its own shares, subject to specific conditions relating to price and volume, in common with many other UK public companies. The buyback authority was obtained to allow the Company to purchase Ordinary Shares through the London Stock Exchange if there was limited liquidity in the market, and if the Directors considered that it was in the best interests of the Company and Shareholders as a whole. Any purchased Ordinary Shares would be held as treasury shares.

The Company sought Shareholder approval at the 2025 AGM to make market purchases of up to 55,932,387 Ordinary Shares. Since the 2025 AGM, the Company has bought back an aggregate 15,330,968 Ordinary Shares, being the Treasury Shares.

At the 2026 AGM, to be held on 15 July 2026, the Company will seek Shareholder approval of a new buyback authority for the Company to make on market purchases of up to 29.04 per cent. of its Existing Issued Share Capital implemented by way of share buyback (the "Share Buyback Authority"). Accordingly, the AGM Notice convening the 2026 AGM, which is set out on pages 19 and 20 of this document, sets out a resolution to be proposed to seek Shareholder approval of the Share Buyback Authority ("Share Buyback Resolution").

The Company has agreed with the Panel that the following persons are acting in concert with each other in relation to the Company: Rupert Labrum and Hedley Clark, being the Executive Chairman and an Executive Director respectively. Accordingly, they (together with their close relatives and the related trusts of any of them) make up a concert party as defined by the Takeover Code (the "Concert Party"). As at the date of this document, the Concert Party has a combined interest in 41,780,673 Ordinary Shares, representing approximately 29.88 per cent. of the Existing Issued Share Capital and approximately 33.56 per cent. of the Voting Share Capital. Further information on the Concert Party and its holdings is set out in section 6 of this Part I and section 4 of Part II of this document.

Any purchases by the Company of its own Ordinary Shares will reduce the Voting Share Capital and may thereby increase the Concert Party's holding of the resultant Voting Share Capital.

Under Rule 9 of the Takeover Code, when any person acquires an interest in shares which (taken together with shares in which the person or any person acting in concert with that person is interested) carry 30 per cent. or more of the voting rights of a company, such person shall extend offers to the holders of the other shares in company. Under Rule 37.1 of the Takeover Code, when a company redeems or purchases its own voting shares, any resulting increase in the percentage of shares carrying voting rights in which a person or group of persons acting in concert is interested will be treated as an acquisition for the purpose of Rule 9. Subject to prior consultation, the Panel will normally waive any resulting obligation to make an offer under Rule 9 if there is a vote of independent shareholders.

The Panel has agreed to waive the obligation to make an offer that would otherwise arise under Rule 9 as a result of the Share Buyback Programme, subject to the approval of the Independent Shareholders. Accordingly, the Rule 9 Waiver Resolution is being proposed at the Annual General Meeting of the Company and will be taken on a poll. The members of the Concert Party will not be entitled to vote on the Rule 9 Waiver Resolution.

The purpose of this document is to provide you with the background to the Rule 9 Waiver, explain why the Independent Director considers the Rule 9 Waiver and the Share Buyback Authority to be in the best interests of the Company and the Independent Shareholders as a whole, and sets out the action required to be taken by Shareholders.

This document also contains the AGM Notice convening the 2026 AGM, at which the Rule 9 Waiver Resolution referred to above will be proposed.

The 2026 AGM is to be held at 9:00 a.m. on 15 July 2026 at Sackville House, 55 Buckhurst Avenue, Sevenoaks, Kent TN13 1LZ.

4.       Share Buyback Programme

At the 2025 AGM, the Company was given authority by Shareholders to purchase up to 55,932,387 Ordinary Shares in aggregate (being approximately 40 per cent. of the number of Ordinary Shares in issue at that time). The Directors have previously sought buyback authorities to allow the Company to purchase Ordinary Shares through the London Stock Exchange if there was limited liquidity in the market, should the Directors consider it to be in the best interests of the Company and Shareholders as a whole.

To date, the Company has completed the buyback of 15,330,968 Ordinary Shares pursuant to the 2025 Share Buyback Authority. The 2025 Share Buyback Authority will expire at the conclusion of the 2026 AGM.

There are no proposed management incentivisation arrangements as part of the Share Buyback Programme.

The Directors intend to seek Shareholders' consent to renew the buyback authority at the 2026 AGM. The terms of the Share Buyback Resolution to be proposed at the 2026 AGM are that the Company be authorised to make on market purchases or tender offer of up to 40,603,066 Ordinary Shares representing approximately 29.04 per cent. of its Existing Issued Share Capital and approximately 32.61 per cent. of the Voting Share Capital. The minimum price that can be paid for an Ordinary Share is 0.2p, being the nominal value of an Ordinary Share. The maximum price that can be paid is the higher of: (i) 5 per cent. over the average of the middle market prices for an Ordinary Share, derived from the Daily Official List of the London Stock Exchange, for the five business days immediately before the day on which the Ordinary Share is contracted to be purchased; and (ii) the higher of the price of the last independent trade, and the highest current independent bid on the trading venue where the purchase is carried out.

The Company will be under no obligation to buyback the maximum number of Ordinary Shares that the Share Buyback Authority allows and will consider the best course of action for the Company in light of the prevailing share price and investment opportunities at the relevant time.

The Board reserves the right to decide how much, if any, of the Voting Share Capital the Company will buyback under the Share Buyback Authority and may decide to not to implement the Share Buyback Programme entirely if the Board decides that it would not be in the best interests of the Company and Shareholders as a whole.

5.       Takeover Code

5.1       Application of the Code

The proposed Share Buyback Authority gives rise to certain considerations under the Takeover Code. The Takeover Code is issued and administered by the Takeover Panel. The Takeover Code applies to all takeover and merger transactions, however effected, where the offeree company is, among other things, a listed or unlisted public company resident in the United Kingdom, the Channel Islands or the Isle of Man (and to certain categories of private limited companies). The Company is a public company registered in the United Kingdom with its Ordinary Shares admitted to trading on AIM and its Shareholders are therefore entitled to the protections afforded by the Takeover Code.

The Takeover Code applies to the Company. Under Rule 9 of the Takeover Code, any person who acquires an interest in shares which, taken together with shares in which that person or any person acting in concert with that person is interested, carry 30 per cent. or more of the voting rights of a company which is subject to the Takeover Code is normally required to make an offer to all the remaining shareholders to acquire their shares.

Similarly, when any person, together with persons acting in concert with that person, is interested in shares which in the aggregate carry not less than 30 per cent. of the voting rights of such a company but does not hold shares carrying more than 50 per cent. of the voting rights of the company, an offer will normally be required if such person or any person acting in concert with that person acquires a further interest in shares which increases the percentage of shares carrying voting rights in which that person is interested.

Further, under Rule 37.1 of the Takeover Code, when a company redeems or purchases its own shares, any resulting increase in the percentage of voting rights carried by the shares in which a person, or group of persons acting in concert, is interested will be treated as an acquisition of interests in shares carrying voting rights for the purpose of Rule 9.1.

An offer under Rule 9 must be made in cash at the highest price paid by the person required to make the offer, or any person acting in concert with such person, for any interest in shares of the company during the 12 months prior to the announcement of the offer.

5.2       Panel Waiver

To enable the Company to buyback Ordinary Shares pursuant to the proposed Share Buyback Authority without triggering a mandatory offer obligation for the Concert Party, the Company has consulted with the Takeover Panel, which has agreed to waive the requirement, subject to the approval of Independent Shareholders, for the Concert Party and individual members of the Concert Party to make a general offer to all Shareholders under Rule 9 of the Takeover Code in circumstances where the Concert Party or individual Concert Party member holding increases.

If the maximum number of Ordinary Shares (being 40,603,066 Ordinary Shares) are bought back and cancelled by the Company pursuant to the proposed Share Buyback Authority and assuming that: (i) no members of the Concert Party participate in the Share Buyback Programme; (ii) no further Ordinary Shares are issued by the Company; and (iii) there are no other changes in the Concert Party holding, then the Concert Party would, in aggregate, be considered to be interested in Ordinary Shares carrying a maximum of 49.80 per cent. of the resultant Voting Share Capital, which is the highest possible percentage of the Voting Share Capital the Concert Party would hold if the Share Buyback Authority is exercised in full.

In addition, based on the assumptions noted above, Rupert Labrum, Chairman of the Company, and his close relatives would, in aggregate, be considered to be interested in Ordinary Shares carrying a maximum of 43.42 per cent. of the resultant Voting Share Capital, which is the highest possible percentage of the Voting Share Capital Rupert Labrum and his close relatives could obtain if the Share Buyback Authority is exercised in full.

If the Rule 9 Waiver is approved, then the Concert Party will not be required to make an offer as a result of the implementation of the Share Buyback Authority. The proposed Share Buyback Authority will expire at the end of the next annual general meeting of the Company following the 2026 AGM or 12 months from the passing of the Share Buyback Resolution, whichever is the earlier.

Accordingly, the obligations under Rule 9 of the Takeover Code would be waived in relation to any exercise of the Share Buyback Authority. Following completion of the Share Buyback Programme, the members of the Concert party will be interested in Ordinary Shares carrying 30 per cent. or more of the voting rights of the Company but will not hold shares carrying more than 50 per cent. of the voting rights of the Company. For so long as they continue to be acting in concert, any increase in their aggregate interests in Ordinary Shares will be subject to the provisions of Rule 9.

Whether or not the Rule 9 Waiver is approved, the Concert Party will not be restricted from making an offer for the Company.

5.3       Concert Party Intentions

The Concert Party has confirmed to the Company that it is not proposing, following any increase in the percentage interests in the Voting Share Capital in which it is considered to be interested as result of the Share Buyback Programme, to seek any change in the general nature of the Company's business. The Concert Party has further confirmed that it has no intention to change the Company's plans with respect to: (i) the composition of the Board, nor the Company's plans with respect to the continued employment of employees and management of the Company (including any material change in conditions of employment) or any material change to the balance of skills and functions of the employees and management; (ii) the Company's future business and its strategic and development plans; (iii) the location of the Company's headquarters or headquarter functions or the location of the Company's place of business; (iv) employer contributions into any of the Company's pension schemes, the accrual of benefits for existing members, nor the admission of new members; (v) redeployment of the Company's fixed assets; or (vi) the continuation of the Ordinary Shares being admitted to trading on AIM.

6.       Background to and details of the Concert Party

6.1       Information on the Concert Party

The Concert Party Directors were both appointed to the Company after a requisition notice was presented to the Company on behalf of Rupert Labrum under section 303 of the CA 2006 in September 2020 to remove the then directors of the Company and replace them with the Concert Party Directors, as announced by the Company on 23 September 2020. The requisition notice was withdrawn, and the Concert Party Directors were appointed to the Board on 27 October 2020, along with Matthew Beardmore, with the previous directors resigning from the Board at the same time or shortly thereafter. The Panel has agreed with the Company that Matthew Beardmore is not a member of the Concert Party.

Rupert Labrum, Executive Chairman, is a former investment banker, who retired after a successful career in the City of London. He was involved with Treasury and funding operations of international banks and building societies. He worked as a fund manager at Gartmore Investment Management and previously ran a proprietary derivatives trading desk at Deutsche Bank. Over the last several years, Mr Labrum has been an active investor in multiple private and publicly quoted companies. He has held notifiable positions in several AIM-quoted companies and is the Company's largest shareholder.

Hedley Clark, an Executive Director, is a Fellow of the Institute of Chartered Accountants in England and Wales. After nine years working in private practice, the last five at KPMG, he left to take up senior financial and management roles in various companies where he gained a wealth of international business experience. This included two successful start-ups. Until the recent sale of the business, for the last 12 years, Mr Clark's principal role had been as the Managing Director of Credence Background Screening Limited, a successful background screening company which, since his initial involvement in 2009, saw significant revenue and profits growth.

6.2       Current interests of the Concert Party

Table 1 below sets out the interests of each member of the Concert Party. Each member listed in Table 1 below are together considered to be acting in concert for the purposes of the Takeover Code and therefore form the Concert Party.

As at the date of this document, the Concert Party is considered to be interested in Ordinary Shares equating to an aggregate of 33.56 per cent. of the Voting Share Capital. As at the date of this document, no other persons with whom the Concert Party is presumed to be acting in concert, including those persons and entities referred to below, had any interests in Ordinary Shares. The current interests of the individual members of the Concert Party in the Ordinary Shares (represented as a percentage of the Voting Share Capital) are set out below:

Table 1

 ¹ Susan Labrum is the spouse of Rupert Labrum, and Georgina Labrum and Lucy Labrum are the adult children of Rupert and Susan.

² Elizabeth Clark is the spouse of Hedley Clark, and Harmim is a company in which Hedley and Elizabeth are directors and shareholders.

³ Represented as a percentage of the Voting Share Capital.

As at the Latest Practicable Date, Rupert Labrum and his close relatives are considered to be interested in Ordinary Shares equating to an aggregate of 29.25 per cent. of the Voting Share Capital of the Company.

6.3       Maximum interests of the Concert Party following the Buyback

If the maximum number of Ordinary Shares (being 40,603,066 Ordinary Shares) are bought back and cancelled by the Company pursuant to the proposed Share Buyback Authority and assuming that: (i) no members of the Concert Party participate in the Share Buyback Programme; (ii) no further Ordinary Shares are issued by the Company; and (iii) there are no other changes in the Concert Party holding, then the Concert Party would, in aggregate, be considered to be interested in Ordinary Shares carrying a maximum of 49.80 per cent. of the resultant Voting Share Capital, which is the highest possible percentage of the Voting Share Capital the Concert Party could obtain if the Share Buyback Authority is exercised in full.

Based on the assumptions noted above, Rupert Labrum and his close relatives would, in aggregate, be considered to be interested in Ordinary Shares carrying a maximum of 43.42 per cent. of the resultant Voting Share Capital, which is the highest possible percentage of the Voting Share Capital Rupert Labrum and his close relatives could obtain if the Share Buyback Authority is exercised in full.

Table 2 below sets out the shareholdings and maximum voting rights of each member of the Concert Party in this event.

Table 2

¹ Susan Labrum is the spouse of Rupert Labrum, and Georgina Labrum and Lucy Labrum are the adult children of Rupert and Susan.

² Elizabeth Clark is the spouse of Hedley Clark, and Harmim is a company in which Hedley and Elizabeth Clark are directors and shareholders.

³ Represented as a percentage of the Voting Share Capital if the Share Buyback was to be exercised in full.

7.       2026 AGM

You will find at the end of this document the AGM Notice convening the 2026 AGM, to be held at 9:00 a.m. on 15 July 2026 at Sackville House, 55 Buckhurst Avenue, Sevenoaks, Kent TN13 1LZ to consider and, if thought appropriate, pass the Resolutions set out therein.

The Rule 9 Waiver Resolution proposes to approve the Rule 9 Waiver conditionally granted by the Takeover Panel for the disapplication of Rule 9 following the undertaking by the Company of the Share Buyback Programme (whether in whole or in part). The Takeover Panel has confirmed that, subject to the Rule 9 Waiver Resolution being passed by the requisite majority of Independent Shareholders on a poll, no mandatory bid obligation would apply to the Concert Party (or any other persons with whom it may be acting in concert) under Rule 9 which would otherwise arise by virtue of the Share Buyback Programme. The Rule 9 Waiver Resolution seeks the approval of the Panel Waiver by Independent Shareholders.

The Rule 9 Waiver Resolution will be proposed as an ordinary resolution. In accordance with the requirements of the Takeover Code, no members of the Concert Party nor any persons with who are considered to be acting in concert with the Concert Party are permitted to vote on the Rule 9 Waiver Resolution.

9.       Recommendation

The Independent Director, Matthew Beardmore, who has been so advised by Cairn, considers the Rule 9 Waiver and Share Buyback Authority to be fair and reasonable and in the best interests of the Independent Shareholders and the Company as a whole. Accordingly, the Independent Director recommends that Independent Shareholders vote, or procure the vote, in favour of the Rule 9 Waiver Resolution and the Share Buyback Resolution (as set out in the AGM Notice) to be proposed at the 2026 AGM as he intends to do in respect of his own interest in 100,000 Ordinary Shares representing approximately 0.08 per cent. of the Voting Share Capital. In providing advice to the Independent Director, Cairn has taken into account the Independent Director's commercial assessments.

In accordance with the provisions of the Takeover Code, the Concert Party Directors (being members of the Concert Party), being Rupert Labrum and Hedley Clark, are considered to be interested in the outcome of the Rule 9 Waiver Resolution and, accordingly, each of them will not vote on the Rule 9 Waiver Resolution.

Thank you, on behalf of the Board, for your continued support of Primorus.

Yours faithfully

Rupert Labrum

Executive Chairman
