(1)

TheOfferor has discussed the Offer with certain of the Offeror's ultimate shareholders and entities controlled by one or more of them ('Permitted Holders'),who collectively hold approximately U.S.$6,000,000 in aggregate principal amount of the Securities. Such Permitted Holders have informed the Offeror of their intention to tender some or all of their Securities for purchase pursuant to the Offer.

Purpose of the Offer

The purpose of the Offer is,amongst other things,to proactively manage the Offeror's expected maturity profile. The Offer also provides Holders with the opportunity to sell their current holdings in the Securities,as more fully described in the Offer to Purchase. To the extent that less than all of the Securities are tendered and accepted for purchase pursuant to the Offer,the Offeror intends to give a notice of optional redemption with respect to such Securities to redeem the Securities that remain outstanding after completion of the Offer in full at par on January 15,2025 in accordance with their terms.

The Offer

The Offeror will pay a purchase price (the 'Purchase Price') per U.S. $1,000 principal amount of Securities validly tendered and accepted for purchase pursuant to the Offer of U.S.$995. In addition,the Offeror will also pay accrued and unpaid interest on the Securities purchased pursuant to the Offer (including Securities tendered according to the Guaranteed Delivery Procedures (as defined in the Offer to Purchase)) from and including the immediately preceding interest payment date,and up to but not including,the Settlement Date (the 'Accrued Interest'). Holders whose Securities are tendered and purchased according to the Guaranteed Delivery Procedures will not receive payment in respect of any interest for the period from and including the Settlement Date (as defined below).

The Purchase Price and the Accrued Interest for the Securities validly tendered (and not validly withdrawn) in the Offer will be paid on the Settlement Date or the Guaranteed Delivery Settlement Date,as applicable (subject to the right of the Offeror to extend the Expiration Deadline and delay the acceptance of Tender Instructions as set out in the Offer to Purchase). If a Holder tenders less than the full amount of its holding of Securities,Tender Instructions must be submitted in respect of a principal amount of Securities so that the principal amount of any Securities held by such Holder after tendering is no less than the Minimum Denomination or an integral multiple of U.S.$1,000 above such Minimum Denomination. The 'Minimum Denomination'is U.S.$200,000.

The Offer is not conditioned on any minimum amount of Securities being tendered. The Offeror's obligation to accept and pay for Securities in the Offer is,however,subject to the satisfaction or waiver of the General Conditions and the condition that the Offeror and/or subsidiaries of IQHL shall have completed the New Debt Financing on terms satisfactory to the Offeror in its sole discretion,with aggregate net proceeds of at least €1,600,000 (equivalent) (the 'Financing Condition').

To the extent that less than all of the Securities are tendered and accepted for purchase pursuant to the Offer,2025 in accordance with their terms. Details of such optional redemption will be provided by the Offeror in a separate redemption notice given in accordance with the terms and conditions of the Securities on or after November 18,2024. This announcement does not constitute a notice of redemption.

Announcements in connection with the Offer will be made by issuing a press release to a widely disseminated news or wire service. Copies of all such announcements,press releases and notices will also be available from the Tender & Information Agent. All documentation relating to the Offer,together with any updates,will also be available on the Offer Websitehttps://deals.is.kroll.com/ineosusdoperated by the Tender & Information Agent for the purpose of the Offer.

A tender of Securities for purchase pursuant to the Offer should be made by the submission of a valid Tender Instruction. If any Holder wishes to tender its Securities but such Holder cannot comply with the procedures for the submission of a valid Tender Instruction prior to the Expiration Deadline,such Holder may tender its Securities according to the Guaranteed Delivery Procedures,as set out in the Offer to Purchase.

Securities purchased by the Offeror pursuant to the Offer are expected to be immediately canceled. Securities that have not been validly tendered and/or accepted for purchase,or which have been tendered and validly withdrawn,pursuant to the Offer will remain outstanding after the Settlement Date.
