Proceeds used to reduce cost of capital while optimising balance sheet structure
NOT FOR PUBLICATION OR DISTRIBUTION IN OR INTO AUSTRALIA, CANADA, JAPAN OR ANY OTHER JURISDICTION IN WHICH SUCH DISTRIBUTION, OFFERS OR SALES, WOULD BE PROHIBITED BY APPLICABLE LAW.
The securities proposed to be offered pursuant to the Offering referred to herein have not been and will not be registered under the US Securities Act of 1933, as amended, and are being offered and sold only outside the United States to persons that are not, and are not acting for the account or benefit of, US persons as defined in Regulation S under the US Securities Act of 1933, as amended.
Johannesburg, Monday, 21 September 2026. Harmony Gold Mining Company Limited (“Harmony”, the “Issuer” or the “Company”) announces the launch of an offering of US$500 million guaranteed senior unsecured convertible bonds due 2031 (the "Bonds") (the "Offering"). Capitalised terms used in this announcement but not defined have the meanings given to them in the terms and conditions of the Bonds (the "Conditions").
The net proceeds from the convertible bond offering are intended to be used for general corporate purposes.
"The Offering reflects a proactive and disciplined approach to balance sheet management from a position of strength. It enhances funding efficiency, diversifies our capital sources and optimises our funding profile. Our capital programme remains fully funded, and we remain confident in Harmony's ability to continue creating long-term value for shareholders," said Beyers Nel, chief executive officer of Harmony.
Payments in respect of the Bonds will be guaranteed by Harmony Gold (Australia) Pty Limited, African Rainbow Minerals Gold Limited, Avgold Limited, Chemwes Proprietary Limited, Golden Core Trade and Invest Proprietary Limited, Freegold (Harmony) Proprietary Limited, Randfontein Estates Limited, Harmony Copper Limited, Harmony Moab Khotsong Operations Proprietary Limited, MAC Copper Limited, Cobar Management Pty. Limited, Metals Acquisition Corp. (Australia) Pty Ltd and Eva Copper Mine Pty Ltd (together, the “Guarantors”).
Main terms of the Bonds
The Bonds will be issued at 100% of their principal amount (i.e. US$200,000 per Bond). Unless previously redeemed, converted or purchased and cancelled, the Bonds will be redeemed at their principal amount on or around 29 September 2031. The Bonds are expected to pay a coupon of between 1.500 % and 2.000 % per annum, payable semi-annually in arrear in equal instalments on 29 March and 29 September of each year and for the first time on 29 March 2027. The initial conversion price is expected to be set within a premium range of 35.0% to 40.0% above the reference share price, equal to the subscription price of the Delta Placement converted into US$ using the USDZAR exchange rate at the time of pricing.
The conversion price will be subject to customary market-standard adjustments, including certain dividend protection provisions, in accordance with the Terms and Conditions of the Bonds.The Bonds will, subject to any future adjustments, be convertible into approximately 18.9m1 ordinary shares of the Issuer, which represents approximately 2.9% of Issuer's current
1 Calculated based on the close price of 18 September 2026 ZAR 319.71 ($19.61556) and assuming a 35.0% conversion premium
issued ordinary share capital. Upon exercise of conversion rights by bondholders, the Issuer will be able to elect, at its discretion, to deliver the shares underlying the Bonds or to exercise its net share settlement option to limit dilution. In case of exercise of the net share settlement option, the value of the shares underlying the Bonds will be delivered to bondholders by making a payment in cash up to the principal amount of the Bonds and delivery of shares representing the difference with the conversion value, calculated daily over a 20 trading day period, and as further described in the Conditions. The conversion period shall commence from the date falling on the 41st business day after the Issue Date (as defined below).
The Issuer will have the option to redeem all, but not some of the Bonds at their principal amount (plus accrued but unpaid interest) in accordance with the Conditions at any time (i) on or after 20 October 2029, if the Parity Value (as defined in the Conditions) is equal to or exceeds US$300,000 for a specified period of time; or (ii) if at any time 85% or more of the principal amount of the Bonds originally issued have been converted and/or redeemed and/or purchased and cancelled (all as more fully described in the Conditions).
The Bonds may be redeemed at the option of each holder of the Bonds at the principal amount (plus accrued but unpaid interest) following the occurrence of a Change of Control or a De-Listing Event (all as more fully described in the Conditions).
The Bonds will be offered by way of an accelerated bookbuild to qualified investors only. The final terms of the Bonds are expected to be announced after pricing which is expected later today, and issue date is expected to be on or around 29 September 2026 (the “Issue Date”). Application is expected to be made for the Bonds to be admitted to trading on the Open Market (Freiverkehr) segment of the Frankfurt Stock Exchange within 30 days following the Issue Date.
In the context of the Offering, the Issuer, the Guarantors and their respective subsidiaries will agree to a lock-up relating to equity and equity-related securities for a period of 90 calendar days from the Issue Date, subject to certain exceptions and waiver by the joint global coordinators and joint
bookrunners of the Offering (the "Joint Global Coordinators" and "Joint Bookrunners").
The Bonds, the guarantee in respect thereof, the ordinary shares into which the Bonds are convertible and other ordinary shares referred to herein (together, the "Securities") have not been and will not be registered under the U.S. Securities Act of 1933, as amended (the "Securities Act"), or the securities laws of any state or other jurisdiction of the United States, and may not be offered or sold within the United States of America or to, or for the account or benefit of, U.S. persons (as defined in Regulation S under the Securities Act ("Regulation S")) except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and in accordance with any applicable securities laws of any state or other jurisdiction of the United States. There will be no public offer of the Securities in the United States. The Bonds are being sold to certain non-U.S. persons in offshore transactions outside the United States of America in reliance on Regulation S. This announcement does not constitute an offer to sell or the solicitation of an offer to buy the Securities, nor shall it constitute an offer, solicitation or sale in any jurisdiction which such offer, solicitation or sale would be unlawful.
Delta Placement
To facilitate hedging for certain subscribers of the Bonds, the Joint Global Coordinators will, on behalf of certain subscribers of the Bonds, organise a simultaneous limited placement of existing ordinary shares (the "Delta Placement") to purchasers procured by the Joint Global Coordinators. The placement price for the short sales in the Delta Placement shall be determined via an accelerated bookbuilding process that will be carried out by the Joint Global Coordinators, but the Issuer will not receive any proceeds from any sale of existing shares in connection with the Delta Placement.
Prospectus
No prospectus pursuant to Regulation (EU) 2017/1129 or the Prospectus Rules: Admission to Trading on a Regulated Market sourcebook (the “PRM”), nor any prospectus which complies with the South African Companies Act, 2008 (as amended) (the "SA Companies Act"), is required in respect of the Offering, and therefore, no prospectus or similar document will be published in connection with the Offering.

The Joint Lead Managers are acting exclusively on behalf of the Issuer and no-one else in connection with the offering. They
will not regard any other person as their respective client in relation to the offering and will not be responsible to anyone other than the Issuer for providing the same protections as to any of their clients or to provide advice in connection with the offering, the Bonds, the contents of this announcement or any other transaction, arrangement or other matter described herein.
The information contained herein is not and is not intended to be exhaustive. It is not advisable to rely on the information contained herein or on its accuracy or completeness.

Each of the Issuer, the Joint Bookrunners and their respective affiliates expressly disclaims any obligation or undertaking to update, review or revise any statement contained herein whether as a result of new information, future developments or otherwise.

UK and EEA Selling Restrictions and Deemed Investor Representations
This announcement and the offering when made are only addressed to, and directed in, Member States of the European Economic Area (the “EEA”) (each, a “Member State”) and the United Kingdom, at persons who are “Qualified Investors” within the meaning of the EU Prospectus Regulation or the paragraph 15 of Schedule 1 to the Public Offers and Admissions to Trading Regulations 2024, as applicable (“Qualified Investors”). Each person in a Member State or in the United Kingdom who initially acquires any Bonds or to whom any offer of Bonds may be made and, to the extent applicable, any funds on behalf of which such person is acquiring the Bonds that are located in a Member State or in the United Kingdom will be deemed to have represented, acknowledged and agreed that it is a Qualified Investor.
Solely for the purposes of the product governance requirements contained within: (a) EU Directive 2014/65/EU on markets in financial instruments, as amended (“MiFID II”); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; (c) local implementing measures in the EEA; (d) Regulation (EU) No 600/2014 as it forms part of United Kingdom domestic law by virtue of the EUWA (“UK MiFIR”); and (e) the FCA Handbook Product Intervention and Product Governance Sourcebook (together, the “Product Governance Requirements”), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any “manufacturer” (for the purposes of the Product Governance Requirements) may otherwise have with respect thereto, the Bonds have been subject to a product approval process, which has determined that: (i) the target market for the Bonds is (a) in the EEA, eligible counterparties and professional clients only, each as defined in MiFID II and (b) in the United Kingdom, eligible counterparties (as defined in the FCA Handbook Conduct of Business Sourcebook) and professional clients (as defined in UK MiFIR); and (ii) all channels for distribution of the Bonds to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Bonds (a “distributor”) should take into consideration the manufacturers’ target market assessment.
However, a distributor subject to Product Governance Requirements is responsible for undertaking its own target market assessment in respect of the Bonds (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels. The target market assessment is without prejudice to the requirements of any contractual or legal selling restrictions in relation to any offering of the Bonds. For the avoidance of doubt, the target market assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II or UK MiFIR; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Bonds.
The Bonds are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA or in the United Kingdom. For these purposes, a retail investor means (a) in the EEA, a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of MiFID II; or (ii) a customer within the meaning of Directive (EU) 2016/97, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II and (b) in the United Kingdom, a person who is neither: (i) a professional client, as defined in point (8) of Article 2(1) of UK MiFIR; nor (ii) a "qualified investor" as defined in paragraph 15 of Schedule 1 to the Public Offers and Admissions to Trading Regulations 2024.
Consequently, no key information document required by Regulation (EU) No 1286/2014, as amended (the “PRIIPs Regulation”) nor any disclosure document required by the FCA Product Disclosure Sourcebook ("DISC"), for offering or selling the Bonds or otherwise making them available to retail investors in the EEA or in the United Kingdom (as applicable) has been prepared and therefore offering or selling the Bonds or otherwise making them available to any retail investor in the EEA or in the United Kingdom may be unlawful under the PRIIPs Regulation, DISC and the Consumer Composite Investments (Designated Activities) Regulations 2024.
In the case of any securities being offered to a potential investor in its capacity as a financial intermediary (as such term is used in Article 5(1) of the Prospectus Regulation or the POATR or PRM, as applicable), such financial intermediary will be deemed to have represented and agreed that the securities acquired by it in the offering have not been acquired on behalf of persons in a Member State or the United Kingdom other than Qualified Investors or persons in Member States or the United Kingdom for whom such financial intermediary has authority to make decisions on a wholly discretionary basis, nor have the securities been acquired with a view to their offer or resale in a Member State or the United Kingdom where this would result in a requirement for publication by the Issuer, the Guarantors, the Joint Lead Managers or any other bookrunner of a prospectus pursuant to Article 3 of the Prospectus Regulation or the POATRs or the PRM, unless the prior written consent of the Joint Bookrunners has been obtained to such offer or resale.
