Offer for Renergen by ASPI - Proactive extension of fulfilment of outstanding offer conditions RENERGEN LIMITED ASP ISOTOPES INC. (Incorporated in the Republic of South Africa) (Incorporated in the State of Delaware, (Registration number 2014/195093/06) United States of America) JSE and A2X Share code: REN (Delaware file number 6228898) ISIN: ZAE000202610 Ticker Symbol: NASDAQ: ASPI LEI:378900B1512179F35A69 ISIN: US00218A1051 Australian Business Number (ABN): 93 998 352 675 LEI: 6488WHV94BZ496OZ3219 ASX Share code: RLT JSE Share Code: ISO ("Renergen") ("ASPI") OFFER FOR RENERGEN BY ASPI – SCHEME OF ARRANGEMENT - PROACTIVE EXTENSION OF FULFILMENT OF OUTSTANDING OFFER CONDITIONS Renergen and ASPI remain fully committed to the Scheme and are still optimistic that the remaining Offer Conditions can be met by 30 September 2025, as provided for in the Circular. However, it is not unusual for the fulfilment of conditions for a transaction of this nature to require additional time when regulatory or 3rd party approvals are required as these are out of the control of both ASPI and Renergen. Key milestone transaction approvals have already been received, including the approval from the Competition Commission which has paved the way for the two companies to plan integration processes and begin collaborating, as detailed in the Renergen SENS released on 14th August 2025. Whilst the parties remain optimistic that the remaining Conditions should be fulfilled (or, where applicable, waived) before 30 September 2025, as originally envisaged in paragraph 5.2.4 of the Circular, ASPI has deemed it prudent to proactively extended the deadline for the fulfilment of the outstanding Conditions, from 30 September 2025 to 28 November 2025, in accordance with paragraph 5.2.5 of the Circular. Both Renergen and ASPI are fully engaged in working together to receive the required approvals as quickly as possible. Once the various Conditions have been met (or if applicable waived), Renergen and ASPI will announce the updated salient dates and times for the Scheme on SENS and on the ASX.
