Increase in Price for the Recommended Acquisition

On 11 September 2026, Tribal announced that it had entered into a conditional sale and purchase agreement (the "Sale and Purchase Agreement") for the sale of the Tribal Group businesses to Thames Bidco Limited, a company controlled by funds and accounts managed or advised by Main Capital Partners (“Main”).

The circular in respect of the Proposed Sale (the "Circular") was published and made available to Tribal Shareholders on 16 September 2026. This announcement should be read in conjunction with the Circular. The Board of Tribal reminds Shareholders that the General Meeting, notice of which is set out in Part IV of the Circular, will be held at 9:30 a.m. on 2 October 2026 at the offices of Investec Bank plc at 30 Gresham Street, London EC2V 7QP in accordance with the timetable set out in the Circular.

Improved terms of the Proposed Sale

The Company is pleased to confirm that it has reached an agreement with Main on an increase in the cash consideration payable for the Group Companies under the Sale and Purchase Agreement from approximately £189.3 million to approximately £231.2 million (the “Improved Sale Terms”). The Improved Sale Terms will result in the Company receiving proceeds of approximately £231.2 million (the “Increased Net Cash Proceeds”) which is equivalent to approximately 105 pence per Ordinary Share.

The Increased Net Cash Proceeds per Ordinary Share represents a premium to Shareholders of approximately:

66.7 per cent to the closing price of 63 pence per Ordinary Share on 10 September 2026, being the Business Day prior to the date of the Company’s announcement on 11 September 2026;

70.6 per cent to the volume weighted average price of 61.6 pence per Ordinary Share in the one month period ended at the close of business on 10 September 2026;

73.0 per cent to the volume weighted average price of 60.7 pence per Ordinary Share in the three month period ended at the close of business on 10 September 2026; and

80.2 per cent to the volume weighted average price of 58.3 pence per Ordinary Share in the six month period ended at the close of business on 10 September 2026.

Recommendation and irrevocable undertakings

The Tribal Directors consider that the Improved Sale Terms are in the best interests of the Company and its Shareholders as a whole. Accordingly, the Directors continue to unanimously recommend that Shareholders vote in favour of the Resolution to be proposed at the General Meeting. Moreover, the Board, who have been so advised by Investec Bank plc as to the financial terms of the Improved Sale Terms, consider the terms of the Improved Sale Terms to be fair and reasonable.

In addition to the irrevocable undertakings to vote in favour of the Resolution at the General Meeting received from the Tribal Directors and certain shareholders, as set out in the Circular, which continue to remain valid in relation to the Improved Sale Terms, the Company announces that new irrevocable undertakings to vote in favour of the Resolution have been received from each of Harwood Capital, Gresham House Asset Management Limited and Schroder Investment Management Limited which will not lapse in the event of any offer being received by the Company at any value. Harwood Capital’s irrevocable undertaking has increased such that it is now in respect of a total of 33,700,000 Ordinary Shares, being approximately 15.7 per cent of the Company’s issued share capital.

In addition to the above, Liontrust Investment Partners LLP has provided an irrevocable undertaking in respect of 16,553,207 Ordinary Shares, being approximately 7.7 per cent of the Company’s issued share capital and RWC Asset Management LLP has provided an irrevocable undertaking in respect of 12,214,264 Ordinary Shares, being approximately 5.7 per cent of the Company’s issued share capital. These irrevocable undertakings will also not lapse in the event of any offer being received by the Company at any value.

The total number of Tribal shares which are subject to irrevocable undertakings to vote in favour of the Resolution is therefore 113,066,571 Ordinary Shares, representing, in aggregate, approximately 52.7 per cent of the Company’s issued share capital. As a consequence, the Resolution is expected to be passed at the General Meeting which the Directors consider to be in the best interests of the Company and its Shareholders as a whole. Further details can be found in Appendix 2 of this announcement.

The Board of Tribal reminds Shareholders that the General Meeting, notice of which is set out in Part IV of the Circular, will be held at 9:30 a.m. on 2 October 2026 at the offices of Investec Bank plc at 30 Gresham Street, London EC2V 7QP.

Terms and conditions

Save as set out in this announcement, the Proposed Sale will be subject to the same terms and conditions as set out in the Circular and the Sale and Purchase Agreement. Tribal shareholders should note that Tribal does not intend to publish a revised Circular for the Improved Sale Terms.

General

The expected timetable of principal events for the Proposed Sale remains as set out on page 6 of the Circular. If any of the dates and / or times in this expected timetable change, the revised dates and / or times will be notified to Tribal Shareholders, with such announcement being made available on Tribal's website at https://legal.tribalgroup.com/transaction-documents.

This summary should be read in conjunction with, and is subject to, the full text of this document and its appendices. The appendices contain details and bases of belief of the anticipated quantified financial benefits of the Improved Sale Terms, together with the related reports from Tribal’s reporting accountant, BDO LLP, and Tribal’s financial adviser, Investec Bank plc, as required under Rule 28 of the Code, and provides underlying information and bases for the reporting accountant’s and advisers’ respective reports. Each of BDO LLP and Investec Bank plc has given and not withdrawn its consent to the publication of its report in this document in the form and context in which it is included.

For the purposes of Rule 28 of the Code, the Updated Quantified Financial Benefits Statement contained in this document is the responsibility of Tribal and the Board.

This document contains statements of the estimated Net Cash Proceeds arising from, or in connection with the Proposed Sale, the Cancellation and the MVL (together, the “Updated Quantified Financial Benefits Statement”).

A copy of the Updated Quantified Financial Benefits Statement is set out below:

The Board, having reviewed and analysed the cash consideration, the cash resources available to the Company and the Company's costs and liabilities and potential costs and liabilities, is highly confident that following Completion of the Proposed Sale, Cancellation and taking into account the expected costs of the MVL, Shareholders will receive Increased Net Cash Proceeds which will total not less than £231,219,773. The Board expects the resulting Increased Net Cash Proceeds per Ordinary Share to be not less than 105 pence per ordinary share in the Company.

The quantified Increased Net Cash Proceeds per Ordinary Share have been calculated on the basis of the following:

Cash consideration of £231,219,773, payable by the Buyer pursuant to the Proposed Sale;

Approximately £8.4 million being accessible to the Company to meet: (i) costs incurred in respect of the Proposed Sale of approximately £2.8 million; and (ii) ongoing PLC costs from Completion of the Proposed Sale until the distribution, together with costs associated with the MVL and with the return of cash to shareholders, of approximately £5.6 million. As described in assumption 8 below, these amounts are expected to be funded from cash transferred to the Company from the Group Companies prior to Completion of the Proposed Sale and therefore will not be deducted from the cash consideration of £231.2 million payable under the Proposed Sale; and

Of the £8.4 million, approximately £0.2 million being recurring costs and approximately £8.2 million being non-recurring costs incurred or expected to be incurred in connection with the Proposed Sale, the Cancellation, the MVL and the return of cash to Shareholders.

The estimated costs are dependent on future actions and circumstances which, by their nature, involve risks, uncertainties and contingencies. As a result, the actual Increased Net Cash Proceeds and Increased Net Cash Proceeds per Ordinary Share received by Shareholders may differ from, or be materially lower than, those estimated in the Updated Quantified Financial Benefits Statement. For the purposes of Rule 28 of the Code, the statements of cash resources available to the Company, the costs incurred or to be incurred in respect of the Proposed Sale, the ongoing PLC costs from Completion of the Proposed Sale until the distribution, as well as costs associated with the MVL, Increased Net Cash Proceeds and Increased Net Cash Proceeds per Ordinary Share contained in this document are solely the responsibility of Tribal and the Board.

There is no guarantee that the Increased Net Cash Proceeds actually received by Shareholders will be as estimated in these statements and the Increased Net Cash Proceeds and Increased Net Cash Proceeds per Ordinary Share should not be interpreted as such.

This Appendix 1 includes a calculation of the estimated Increased Net Cash Proceeds and Increased Net Cash Proceeds per Ordinary Share.

This Appendix 1 also includes reports from Tribal's reporting accountant, BDO LLP, and its financial adviser, Investec Bank plc, in connection with the anticipated Updated Quantified Financial Benefits Statement, as required pursuant to Rule 28.1 of the Code, and provides underlying information and bases for the reporting accountant's and financial adviser's respective reports. Investec Bank plc, as financial adviser to Tribal, has provided such a report for the purposes of the Code stating that, in their opinion and subject to the terms of the report, the Updated Quantified Financial Benefits Statement, for which the Board are responsible, has been prepared with due care and consideration. Each of BDO LLP and Investec Bank plc has given and not withdrawn its consent to the publication of its report in this document in the form and context in which it is included.

Further information on the bases of belief supporting the Updated Quantified Financial Benefits Statement, including the principal assumptions and sources of information, is set out below.

Basis of calculation of the Increased Net Cash Proceeds and Increased Net Cash Proceeds per Ordinary Share

In preparing the Updated Quantified Financial Benefits Statement, Tribal has relied on a combination of its own internal information, existing agreements, invoices, quotations, publicly available information, external professional advice, estimates and assumptions.

Where appropriate, the cost assumptions have been risk-adjusted by the Board, reflecting the Board’s assessment of the likelihood, timing and quantum of the relevant costs.

In arriving at the Updated Quantified Financial Benefits Statement, the Tribal Directors have made the following assumptions.

Factors outside the influence of the Company

Following Completion of the Proposed Sale, the resolutions required to approve the Cancellation, place the Company into the MVL and appoint the liquidators being passed by Shareholders at the General Meeting convened for this purpose;

the time period from Completion of the Proposed Sale to the final distribution under the MVL being six months and no costs being incurred by the Company subsequent to that time;

no claims being made under any parental guarantees during the period between completion of the Proposed Sale and completion of the MVL;

no unmitigated tax liabilities arising from the Proposed Sale beyond those identified from external advice received;

there being no material change in prevailing foreign exchange rates or interest rates;

there being no change in tax legislation, tax rates or other applicable legislation or regulation in any relevant jurisdiction which could materially affect the costs incurred in connection with the Proposed Sale, the Cancellation, the MVL or the return of cash to Shareholders; and

no material litigation, arbitration, regulatory investigation, claim or other proceedings being commenced or threatened against the Company, and no other material liability or adverse event arising, in each case which would materially reduce the amount of cash available for return to Shareholders.

Factors within the influence of the Company

all liabilities, including transaction expenses, outstanding at the time of Completion of the Proposed Sale being identified correctly and the Company being able to transfer sufficient cash from Group Companies prior to Completion of the Proposed Sale to settle these, such that the proceeds of the Proposed Sale do not need to be used to settle outstanding liabilities on Completion of the Proposed Sale;

no material additional costs being incurred in relation to the Proposed Sale and post Proposed Sale period beyond the amounts set out in the Sale and Purchase Agreement and / or identified prior to publication of this document;

there being no costs to the Company arising from the post Proposed Sale Transitional Services Agreement between the Company and Tribal Education Ltd;

including potential vesting share options under the Tribal Share Plans, Tribal’s fully diluted share capital is 220,397,024. Taking into account the portion of the aggregate cash consideration which will be offered to participants in the Tribal Share Plans in return for the release of their options, Tribal’s effective fully diluted share capital is 220,209,308 using the treasury stock method; and

the Company not seeking to make an acquisition or acquisitions which constitute a reverse takeover under AIM Rule 14 after Completion of the Proposed Sale.

Timing of realisation

Subject to Completion of the Proposed Sale, approval by Shareholders of the resolutions required to place the Company into the MVL and the appointment of the liquidators, the Board expects that the Increased Net Cash Proceeds to be distributed to Shareholders will be distributed in two tranches, (i) the first distribution within 30 days of the liquidators being appointed (expected in Q1 2027), followed by (ii) a final distribution within six months of Completion of the Proposed Sale (expected in Q2 2027).

Reports

As required by Rule 28 of the Code, BDO LLP, as reporting accountants to Tribal, and Investec Bank plc, as financial adviser to Tribal, have provided the reports required under the Code.
