NOTIFICATION OF THE AVAILABILITY OF THE SUSTAINABILITY COMPLIANCE CERTIFICATE AND SUSTAINABILITY MARGIN ADJUSTMENT EVENT

Notice is hereby given to each noteholder of ZAR535,000,000 senior unsecured floating rate notes due 11   September   2026 (AECI05) and ZAR465,000,000 senior unsecured floating rate notes due 11   September   2028 (AECI06), (together referred to as the Notes), issued under the Company's ZAR5,000,000,000 Domestic Medium Term Note Programme, pursuant to the section headed "Terms and Conditions of the Notes" (the Terms and Conditions) in the programme memorandum dated 12 December 2024, as amended and restated from time to time, read with each of the amended and restated applicable pricing supplements in respect of the Notes (the Applicable Pricing Supplements), of the availability of the Sustainability Compliance Certificate (as defined in the Applicable Pricing Supplements) for the financial year ended 31   December   2025, on the Company's website at https://investor.aeciworld.com/debt-investors.php . A copy of the accompanying Sustainability Assurance Report is also available on the Company's website at https://investor.aeciworld.com/results-reports-presentations.php#integrated-annual-reports .

Capitalised terms used herein which are not otherwise defined shall bear the meaning ascribed thereto in the Terms and Conditions and/or the Applicable Pricing Supplements.

Noteholders are advised that, as a result of AECI having achieved none of the SPTs in respect of each of the three KPIs for the financial year ended 31 December 2025, the Initial Margin applicable to the Notes shall be increased by 10 (ten) basis points and will apply for the Interest Period commencing after the Sustainability Compliance Certificate Delivery Date, being 11   June   2026.

The Company did not achieve its SPTs for Carbon Footprint Efficiency and Effluent Discharge Efficiency for the reporting period, primarily due to operational variability which resulted in fixed environmental loads being distributed across lower production volumes, thus adversely affecting efficiency ratios. In addition, actual production volumes were lower than the levels assumed during the target setting phase. Assumed production levels were based on AECI's strategic ambition at the time to achieve a double EBITDA growth trajectory, as well as an expected return to pre-COVID production levels.

The Group marginally missed its SPT for female representation, achieving 1 percent below the applicable SPT. This shortfall was primarily attributable to organisational restructuring and divestments undertaken during 2025, which impacted workforce composition at management level. Notwithstanding this outcome, the Company remains committed to advancing gender diversity and continues to implement targeted initiatives to support the progression and retention of female talent across the organisation.

Accordingly, the Margins applicable to the Notes for the Interest Period commencing on 11   June   2026 are as follows:

Bond code :	AECI05
ISIN :	ZAG000199258
Margin :	3 Month ZAR-JIBAR plus 149 basis points
Bond code :	AECI06
ISIN :	ZAG000199266
Margin :	3 Month ZAR-JIBAR plus 160 basis points
