Additional Explanations

As per our previous announcements regarding debt capital market instrument issuance, our Company plans to issue Eurobonds to qualified investors abroad, with a tenor of between 5 to 7 years, within the current issue ceiling approved by the Capital Markets Board of Turkey. The Eurobonds will be subject to 144A/RegS regulations. In this respect, starting from February 15, 2019, high level management of our Company will carry out investor meetings arranged by mandated banks, in London, Boston and New York. The final decision on the bond issuance, the issuance amount and conditions, will be determined according to market developments following these meetings. The Eurobonds are planned to be listed on the Euronext Dublin when the issuance is completed. The Eurobonds are expected to be rated "BB-" by S&P Global Ratings and "BB+" by Fitch Ratings. BofA Merrill Lynch, Citi, ING, MUFG and Société Générale have been mandated for the issuance.
