Introduction

On 23 June 2026, Hena Holdings Ltd. ("Bidco"), a company wholly owned by Dr Hend El Sherbini (the Chief Executive Officer of IDH) and her mother, Dr Moamena Abdul Wahab Kamel, announced that it had acquired 126,000,000 IDH Shares from Actis IDH Limited (the "Seller"), an entity controlled by funds managed by Elliott Investment Management L.P. ("Elliott"), which completed on 23 June 2026 (the "Elliott Transaction") and that, as a result of the Elliott Transaction, under Rule 9 of the Takeover Code, Bidco was required to make  a mandatory cash offer for the IDH Shares not already held by Bidco. Accordingly, on 23 June 2026, Bidco announced a mandatory final cash offer (the "Offer") to be made by Bidco for all of the IDH Shares not already held by Bidco at a price of US$0.50 (50 cents) in cash per IDH Share (the "Rule 2.7 Announcement").

The offer document containing the full terms and conditions of the Offer and the procedures for acceptance (the "Offer Document") was published and posted to IDH Shareholders on 8 July 2026.

Important Notice to US holders of IDH Shares

The Offer relates to shares of a Jersey company and is being made by means of a contractual takeover offer under the Takeover Code and under the laws of England and Wales. The Offer is made in the United States pursuant to all applicable laws and regulations, including, to the extent applicable, Section 14(e) and Regulation 14E under the US Exchange Act and otherwise in accordance with the requirements of the Takeover Code. Accordingly, the Offer is subject to disclosure and other procedural requirements, including with respect to withdrawal rights, offer timetable, settlement procedures and timing of payments that are different from those applicable under US domestic tender offer procedures and law. The Offer is made in the United States by Bidco and no one else.

Furthermore, the payment and settlement procedures with respect to the Offer comply with the relevant United Kingdom rules, which differ from US payment and settlement procedures, particularly with regard to the date of payment of consideration.

In accordance with, and to the extent permitted by, the Takeover Code and normal UK market practice, Canaccord Genuity Limited and their respective affiliates may continue to act as exempt principal traders or exempt market makers in IDH Shares on the London Stock Exchange and will engage in certain other purchasing activities consistent with their respective normal and usual practice and applicable law, as permitted by Rule 14e-5(b)(9) under the US Exchange Act. In addition, Bidco, its affiliates, their advisers, and their nominees or brokers (acting as agents) may make certain purchases of, or arrangements to purchase, shares in IDH outside the Offer, such as in open market purchases or privately negotiated purchases, during the period in which the Offer remains open for acceptance. If such purchases or arrangements to purchase were to be made, they would be made outside the US and would comply with applicable law, including United Kingdom laws and the US Exchange Act. Any information about such purchases or arrangements to purchase shall be disclosed as required under United Kingdom laws and will be available to all investors (including US investors) via the Regulatory Information Service on www.londonstockexchange.com.

The financial statements and all financial information included in the Offer Document have been prepared in accordance with the International Financial Reporting Standards as adopted by the European Union and thus may not be comparable to financial statements and information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the US. Neither the Offer nor the Offer Document have been approved or disapproved by the Securities and Exchange Commission, any state securities commission in the United States or any other US regulatory authority, nor have such authorities passed upon or determined the adequacy or accuracy of the information contained in the Offer Document or the merits of the Offer. Any representation to the contrary is a criminal offence in the US.

The receipt of cash by a US holder as consideration for the transfer of its IDH Shares pursuant to the Offer 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 US holder of IDH Shares is urged to consult their independent professional adviser immediately regarding the tax consequences of the Offer applicable to him or her.

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 pm (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).
