EXHIBIT 99.1

ANNOUNCEMENT REGARDING CAPITAL MARKETS BOARD (“CMB”) REQUEST

Subject: Statement made pursuant to Circular VIII, No: 54 of the Capital Markets Board.

Istanbul Stock Exchange

ISTANBUL

Special Subjects:

This is an announcement as per CMB request dated May 21, 2009 in regards to the Information and Communication Technologies Authority (“ICTA”)’s reduction in the termination rates of our Company and decision on retail pricing.

Above requests of ICTA were already made public such that the new termination rates issued by ICTA to be effective May 1, 2009 is announced on April 14 2009. On the other hand, the potential impact of ICTA’s decision in regards to the retail pricing on our financials is publicly made avaible on May 13, 2009 via our 1Q 2009 financial result announcement and on our website at www.turkcell.com.tr.

We believe that some of ICTA’s decisions constitute interference with our retail pricing and may be in conflict with our license agreement and fair competition laws. Therefore, we are evaluating legal actions to protect our rights.
