Additional information xvi
MACOM is subscribing for 151,515,151 new Ordinary Shares in IQE plc at a price of 19.8 pence per share for an aggregate subscription price of £30,000,000 pursuant to a Subscription Agreement dated 27 April 2026. In addition, MACOM is subscribing for (i) £15,000,000 of secured convertible loan notes constituted by a Convertible Loan Note Instrument dated 28 May 2026, and (ii) warrants to subscribe for Ordinary Shares constituted by a Warrant Instrument dated 28 May 2026. The warrants are exercisable at a subscription price of 19.8 pence per share following the Company's redemption of the convertible loan notes during the 60-month subscription period. The warrants and convertible loan notes are linked instruments - if the convertible loan notes convert into shares, the corresponding proportion of warrants will automatically lapse. Accordingly, the warrants and convertible loan notes represent alternative (not cumulative) rights to acquire the same 75,757,575 Ordinary Shares. For completeness, if the Convertible Loan Notes were to convert in full (or, alternatively, the warrants were to be exercised in full), MACOM would hold approximately 14.7% of the shares and voting rights of IQE.
