MTNH-Credit Rating Amendment MOBILE TELEPHONE NETWORKS HOLDINGS LIMITED Incorporated in the Republic of South Africa Registration number 1993/001411/06) (“MTNH”) or (“the Company”) MTN Group Limited-Credit Rating Review by S&P Global(“S&P”) On 1 April 2020, S&P took rating actions on Nigeria-exposed corporate issuers that are rated at or above sovereign. S&P also considered the effects that lower GDP growth, potential currency movements, and lower oil prices could pose to issuers' earnings prospects and leverage, within the context of their exposure to coronavirus (COVID-19)-related local and global developments. S&P’s rationale for the rating review was that the Nigeria- exposed issuers would be facing the following conspicuous risks that would have an impact on the issuers: • lower demand for a wide variety of products and services due to a likely broad-based COVID-19-related economic recession, negative effects on Nigeria's government finances and • oil-related industries following the recent slump in oil prices, and risks of Nigerian naira (NGN) depreciation versus other global currencies. S&P, stated however, that they foresaw COVID-19 as having a modest effect on MTN's financial metrics, given the heightened importance of telecommunications during a period of restricted movement. MTN Group Ltd - S&P lowered the long-term issuer credit rating to 'BB' from 'BB+' and maintained the negative outlook. Mobile Telephone Networks Holdings Ltd - S&P lowered the issuer credit and issue ratings to 'BB' from 'BB+' and maintained the negative outlook. MTN (Mauritius) Investments Ltd - S&P lowered the issue rating to 'BB' from 'BB+'. The '3 (65%)' recovery rating is unchanged. Furthermore, the South African national scale rating was also lowered to 'zaAA' from 'zaAAA'. Notwithstanding the above, MTN Group’s stand-alone credit profile remains unchanged.
