IQE plc

Result of Placing

IQE plc ("IQE" or "the Company"), a leading supplier of compound semiconductor wafer products and advanced material solutions to the global semiconductor industry, is pleased to announce the result of the Placing which was announced on 17 May 2023.

A total of 150,000,000 new Ordinary Shares in the Company (the "Placing Shares") have been placed by Peel Hunt LLP ("Peel Hunt") and Numis Securities Limited ("Numis") (together, the "Joint Bookrunners") at a price of 20 pence per Placing Share (the "Issue Price"), raising gross proceeds of £30 million (before expenses). The Company confirms that certain Directors (the "Participating Directors") have subscribed for, in aggregate 12,700,000 Placing Shares at the Issue Price.

The Issue Price of 20 pence per Placing Share represents a discount of approximately 14.9 per cent. to the closing price of 23.5 pence per existing Ordinary Share on 17 May 2023. The Placing Shares being issued together represent approximately 18.6 per cent. of the existing issued ordinary share capital of the Company immediately prior to the Placing.

Related Party Transactions and Participating Directors

Lombard Odier Asset Management (Europe) Limited ("Lombard Odier") has agreed to subscribe for 50,000,000 Placing Shares at the Issue Price.

The participation of Lombard Odier constitutes a related party transaction under rule 13 of the AIM Rules. Accordingly, the Directors consider, having consulted with the Company's  nominated adviser, that the terms of the transaction are fair and reasonable insofar as the Company's shareholders are concerned.

The Participating Directors have subscribed for, in aggregate 12,700,000 Placing Shares at the Issue Price. The number of Placing Shares subscribed for by each of the Participating Directors pursuant to the Placing and their resulting shareholdings on Admission, are set out below:

The Placing, is conditional on, amongst other things, Admission becoming effective and the Placing Agreement between the Company, Peel Hunt and Numis becoming unconditional and not being terminated in accordance with its terms.

In accordance with the FCA's Disclosure Guidance and Transparency Rules, following this issue of the new Ordinary Shares, the Company's issued share capital consists of 955,522,578 ordinary shares. The Company holds 4,115 Ordinary Shares in treasury. Therefore, the total number Ordinary Shares with voting rights in the Company is 955,518,463.
