Credit Rating Placed on CreditWatch by S&P Global Ratings - BIMTN 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 Placed on CreditWatch by S&P Global Ratings (“S&P”) On 20 September 2018, S&P Global Ratings (S&P) placed its ‘BB+’ foreign and local currency long-term issuer credit ratings on South Africa-based MTN Group Limited(“MTN”) and its subsidiary being the issuer, Mobile Telephone Networks Holdings Limited (MTNH)on CreditWatch negative. S&P has also placed their long-term issue rating on senior unsecured notes issued by MTN Investment Limited (Mauritius) on CreditWatch negative. The South Africa national scale ratings on MTN have been affirmed at ‘zaAAA’. The CreditWatch placements by S&P follow the recent SENS released by MTN on 30 August 2018 and 4 September 2018, in relation to the announcements made by the Central Bank of Nigeria (“CBN”) and the Nigerian Attorney General, respectively. S&P’s CreditWatch placement rationale is based on the uncertainty with regards to these recent announcements and the potential implications on MTN’s credit profile since MTN Nigeria Communications Limited (“MTN Nigeria”) is a significant contributor to MTN's EBITDA (about 30%). According to S&P, the announcement reflects a material increase in risk to the ratings, primarily as a result of reduced consistency of Nigerian government policy implementation in relation to MTN. MTN’s Management remain resolute that MTN Nigeria has not committed any offences and will vigorously defend its position. MTN’s Management will continue to engage with the relevant authorities on all these matters and will provide further information as and when available.
