Director/PDMR shareholding Lonmin Plc (Incorporated in England and Wales) (Registered in the Republic of South Africa under registration number 1969/000015/10) JSE code: LON Issuer Code: LOLMI & ISIN : GB00BYSRJ698 ("Lonmin") 13 April 2017 Lonmin Plc Director/PDMR shareholding Pursuant to Article 19 of the EU Market Abuse Regulation, Lonmin Plc (the “Company”) provides notification of the grant of nil-cost share awards granted on 13 April 2017 under the Company’s Long Term Incentive Plan (“LTIP Awards”) to Ben Magara, Chief Executive Officer and Barrie van der Merwe, Chief Financial Officer. The LTIP Awards are subject to a performance condition comprising two metrics, each assessed independently: - CROIC (Cash Return On Invested Capital) averaged over three financial years. This measures net operating profit after tax (eliminating the impact of depreciation and impairment compared to invested capital); and - TSR (Total Shareholder Return) measured over a three year period relative to the median of a comparator group comprising PGM mining peers, all of whom operate principally in South Africa. Following feedback from shareholders, the Remuneration Committee has amended the vesting schedule (as outlined in the Company’s Annual Report and Accounts 2016) to eliminate any vesting below median performance.
