Moscow, Russia – August 10, 2012 – Rostelecom OJSC (MICEX - RTS: RTKM, RTKMP; OTCQX: ROSYY), Russia’s national telecommunications operator, today announces that its revenues for the first half of 2012 under Russian Accounting Standards (“RAS”) amounted to RUB 142.9 billion. Rostelecom’s sales profit totalled RUB 18.5 billion, its profit before tax was RUB 29.5 billion and net profit equalled RUB 19.6 billion.

The Company would like to draw attention to the following:

Rostelecom’s financial results under RAS for the first half of 2011 do not include any contribution from the seven regional telecom operators or OJSC Dagsvyazinform, which were merged with Rostelecom on April 1, 2011. The Company’s results under RAS for the first half of 2012 do however comprise of results from the combined Rostelecom, and therefore include contributions from the seven regional operators and from OJSC Dagsvyazinform, but they exclude any contribution from Rostelecom OJSC subsidiaries, including NTK and mobile subsidiaries. Rostelecom’s balance sheet as at June 30, 2012, also comprises contributions from all of the companies merged into the new Rostelecom on April 1, 2011 but it excludes contributions from Rostelecom’s mobile subsidiaries and NTK. Direct like-for-like comparisons of the Company’s financial performance for the first halves of 2011 and 2012 under RAS are therefore not possible.

Furthermore, some costs recorded during the first quarter of 2012 under RAS are booked in the second quarter of 2012, while under International Financial Reporting Standards such costs are included in the reporting period they occur.

Rostelecom intends to publish its key financial and operating results according to the Company’s consolidated statements for the first six months of 2012 on August 30, 2012. These statements will include contributions from Rostelecom as well as the seven merged regional operators, OJSC Dagsvyazinform and their subsidiaries, including NTK.
