POSTING OF CIRCULAR AND NOTICE OF EGM

Johannesburg. Monday, 11 June 2018. Harmony advises that the Company has made available to download on its website, www.harmony.co.za/invest, today, a circular to Harmony shareholders. The circular will be posted on or about Tuesday, 12 June 2018.

INTRODUCTION

Harmony shareholders (“ Shareholders ”) are referred to the announcements released by the Company on 5 June and 6 June 2018, in which it advised that in terms of existing authorities granted by Shareholders, it concluded an accelerated bookbuild offering through the subscription by qualifying investors of 55,055,050 new Harmony shares at a price of ZAR19.12 per share (the " Placing Price ") for an aggregate consideration of approximately ZAR1.05 billion (US$82 million) (the " Placing ”).

Harmony remains proactively engaged in accelerating transformation of the mining sector and the economy overall. Accordingly, the Board has identified that it is of strategic importance to ensure ARM's continued contribution to Harmony’s BEE credentials at the same ownership level as before the Placing and consequently, the Board is proposing to issue 11,032,623 new Ordinary Shares at the Placing Price to ARM.

In turn, African Rainbow Minerals Limited (" ARM "), Harmony's long-term anchor strategic black economic empowerment (" BEE ") partner, has agreed to subscribe for 11,032,623 shares at the Placing Price (" ARM Placing ") to ensure that ARM will hold the same shareholding percentage of 14.29% of the issued ordinary share capital of the Company as before the Placing and the issue of shares to the Community Trust and Employee Trust as previously announced and approved by shareholders.

The ARM Placing will be carried out under the vendor consideration placing rules in terms of paragraph 5.62 of the JSE Listings Requirements. The proceeds raised from the ARM Placing will be used to repay part of the outstanding bridge loan raised for the acquisition of Moab Khotsong.

Given that ARM may be “ related or inter-related ” (as such terms are construed in section 2 of the Companies Act, No. 71 of 2008, as amended (" Companies Act ")) to the chairman of the Company, and consequently, as prescribed by section 41(1)(b) of the Companies Act, the Board has determined that notwithstanding their authority to deal with a certain number of the authorised but unissued shares in their discretion as granted at the 2017 annual general meeting, no issue of shares can be made to ARM without first obtaining the approval of Shareholders by way of special resolution.

Accordingly, Harmony has issued a circular, incorporating a notice of Extraordinary General Meeting (" EGM "), to download on its website, www.harmony.co.za/invest, today.

NOTICE OF EGM

Notice is hereby given to the Shareholders that a general meeting will be held at the Hilton Hotel, 138 Rivonia Road, Sandton, Johannesburg, South Africa at 11:00 (South African Standard Time) on 12 July 2018.
