OPERATING REVIEW

Sistema's consolidated revenues increased by 39% year on year in the third quarter to US$ 2,863 million and by 38% to US$ 7,461 million for the nine months of 2006, as a result of robust performance by the Group's Telecommunications segment and healthy growth of the Group's non-telecommunications operations. The non-telecommunications businesses accounted for 27% of Group consolidated revenues in the third quarter and 28% for the year to date, compared to 20% and 21% for the corresponding periods of 2005. The organic year on year and like for like growth was 33% in the quarter and 31% for the first nine months period, and amounted to US$ 2.8 billion in the third quarter of 2006 and to US$ 7.0 billion for the year to date, excluding businesses acquired or divested since the end of the third quarter of 2005.

Group OIBDA increased by 56% year on year in the third quarter, and by 31% year on year from US$ 2.3 billion to US$ 3.0 billion for the nine month period. The Group's OIBDA margin increased from 43% to 48% in the third quarter, which reflected the reduction in the cost structure of MTS and a one off gain from sale of a subsidiary holding 35% interest in Sistema-Invest, the owner of the Group's energy companies in the Republic of Bashkortostan, for a total cash consideration of US$ 201.0 million. Group OIBDA margin for nine months period declined slightly from 43% to 41% as a result of lower margin in the Telecommunications, Technology, Insurance and Retail segments, partially offset by the recognition of gain on disposal of 35% share in Sistema-Invest (the holder of investments in Bashkortostan energy companies) of US$ 175.0 million.

Group operating income was up 72% year on year in the quarter from US$ 612.2 million to US$ 1,054.4 million, and by 35% from US$ 1.6 billion to US$ 2.1 billion for the nine months period. The operating margin in the third quarter was 37%, compared to 30% a year ago and was 28% for the nine months period, compared to 29% for the corresponding period of last year.

Consolidated depreciation and amortization expense was up by 18% year on year in the quarter and by 24% for the nine months period, following the growth in the Group's depreciable asset base, and change in estimate for the useful lives of analogue equipment of Comstar UTS in amount of US$ 6.4 million for the nine months of 2006.

Selling, General and Administrative expenses rose by 25% for the quarter and by 47% for the first nine months, from US$ 354.3 million to US$ 443.3 million and from US$ 928.7 million to US$ 1,368.2 million, respectively. US$ nil in the quarter and US$ 94.0 million for the nine months of 2006, included in S,G&A expense, reflects the fair value of non-cash compensation received by employees.

The effective tax rate increased from 29% to 30% for the year to date, as a result of foreign gains on the exchange of non-ruble denominated long term debt.

The increase in minority interest reflects changes both in net income of the Group and ownership's share in the Group's companies.

Net income in the third quarter was up 142% year on year to US$ 500.0 million from US$ 206.6 million. For the nine-month period, the net income growth was 87% from US$ 434.2 million to US$ 810.1 million.

The growth was primarily organic with no scale acquisitions made during the quarter with the exception of Dagtelecom, which contributed US$ 8.6 million to MTS's revenues.

The mobile operator added 9.4 million subscribers during the first nine months of 2006. Revenues for the first nine months of 2006 increased by 24% year on year to US$ 4.6 billion from US$ 3.7 billion.

MTS results for the third quarter of 2006 showed a year on year decrease in average monthly service revenue per subscriber ("ARPU") for the Russian customer base from US$ 9.0 to US$ 8.6 (including all network revenue). Compared to the first quarter of 2006, MTS' ARPU increased from US$ 6.6 to US$ 8.6.

Comstar UTS generated 34% year on year revenue growth in the third quarter and 30% growth for the nine month period, from US$ 217.4 million to US$ 291.8 million and from US$ 636.8 million to US$ 828.2 million, respectively, reflecting robust growth in organic revenues, as well as US$ 26 million contribution received by MGTS from the federal budget for the discounts granted to certain categories of residential subscribers of MGTS prior to January 1, 2005 and US$ 15.7 million from the introduction of CPP ("Calling Party Pays") on July 1, 2006. Data and internet services to residential users were up 32% year on year and accounted for 87% of total residential revenues of the alternative segment for the quarter and 82% for the nine month period.

Segment OIBDA was up 30% year on year in the quarter and up 19% for the nine month period, with OIBDA margin of 54% in the third quarter and 50% for the nine months period, resulting from significant growth in operations. MTS' OIBDA in the third quarter increased by 29% quarter on quarter from US$ 754.9 million to US$ 976.8 million3. OIBDA for the nine month period increased by 18% from US$ 2.0 billion to US$ 2.3 billion. OIBDA margin increased by 5% from 49% in the second quarter to 54% in the third quarter as a result of the cost reduction programme and new marketing initiatives, introduced by the management during the period. Comstar UTS reported a 19% increase in OIBDA from US$ 96.2 million to US$ 114.6 million in the quarter and a 24% increase for the nine month period, from US$ 269.8 million to US$ 333.3 million.

The year on year increase in segment net income was due to the higher contribution from MTS of US$ 486.3 million (US$ 347.2 million in 2005) in the third quarter and of US$ 965.4 million (US$ 883.8 million) for the nine month period as a result of improved underlying performance of the company.

Technology

[TABLE OMITTED]

The Technology segment of Sistema, which includes Sitronics, generated 54% growth year on year in revenues to US$ 349.0 million in the third quarter and 60% increase year on year to US$ 1,054.6 million for the nine month period, and accounted for 10% and 11%, respectively, of Group revenues in 2006, compared to 7% and 8%, respectively, for the same periods of 2005. The growth was primarily organic. The acquisition of Intracom Telecom contributed US$ 306.1 million in revenues and US$ 22.5 million in OIBDA to the segment results. Following the acquisition of Intracom Telecom SITRONICS margin slightly decreased reflecting a lower margin of the new subsidiary's business. The growth was primarily driven by Telecom Solutions division.

SITRONICS is currently re-evaluating the accounting treatment of certain contracts with Group companies to apply a more conservative approach to recognition of revenue from sales of its own software products. This approach implies an extended period of revenue recognition of the transaction, including the period of warranty services. We do not expect that the results of this re-evaluation will materially impact Sistema consolidated accounts.

Real Estate

[TABLE OMITTED]

The Real Estate segment, which includes Sistema Hals, reported almost five-fold revenue growth year on year to US$ 161.1 million in the nine months of 2006. Its revenues almost doubled year on year to US$ 54.6 million in the third quarter. This growth in revenues for the nine months of 2006 resulted primarily from sale of "Pokrovka" project, an office and hotel building in the center of Moscow, for US$ 84.4 million and "Yartsevskaya 27" project, residential premises in Moscow, for US$ 20.3 million, as well as US$ 10 million increase in revenues of Sistema Hals construction projects documentation subsidiary.

The increase in profitability was a result of contribution to OIBDA on the sale of "Pokrovka" project in the amount of US$ 41.6 million and recognition of profit from sale of a part of "Yartsevskaya 27" project for US$ 9.1 million. Revenues on the construction-type contracts were recognized using the percentage of completion method, used for accounting for long-term contracts. Progress towards completion is measured by percentage of costs incurred to date to the estimated total costs at completion for each contract, while revenues only start to be recognized upon conclusion of the agreement for sale.

The Insurance segment, which includes ROSNO, increased revenues by 35% year on year to US$ 163.4 million in the third quarter and by 39% year on year in the nine months of 2006.

[TABLE OMITTED]

The Retail segment of the Group, which includes Detsky Mir, the specialist children's goods retailer, increased its revenues by 42% year on year in the third quarter to US$ 82.3 million and by 94% year on year to US$ 200.2 million for the year to date. The organic revenue growth resulted from the opening of fifteen new retail stores during the nine months of 2006. These stores contributed US$ 33.9 million in sales, or 17% of total revenues for the first nine months of 2006. S-Toys, the wholesaler of consumer goods, accounted for US$ 21.7 million, or 26% of the segments's total revenues in the third quarter of 2006 and for US$ 30.5 million, or 15% of revenues in the nine months period of 2006.

The Company's profitability was adversely affected during the first half of 2006 due to the expansion of its retail network: Detsky Mir now has 58 stores in 21 cities of Russia, compared to 34 stores a year ago. The growth in retail network will enable the company to benefit from the increased purchasing and sales power, and will allow it to secure the footprint in the prime segment of the retail market.

Attachment A

Non-GAAP financial measures. This press release includes financial information prepared in accordance with accounting principles generally accepted in the United States of America, or US GAAP, as well as other financial measures referred to as non-GAAP. The non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information prepared in accordance with US GAAP.

Operating Income Before Depreciation and Amortization (OIBDA) and OIBDA margin. OIBDA represents operating income before depreciation and amortization. OIBDA margin is defined as OIBDA as a percentage of our net revenues. Our OIBDA may not be similar to OIBDA measures of other companies; is not a measurement under accounting principles generally accepted in the United States and should be considered in addition to, but not as a substitute for, the information contained in our consolidated statement of operations. We believe that OIBDA provides useful information to investors because it is an indicator of the strength and performance of our ongoing business operations, including our ability to fund discretionary spending such as capital expenditures, acquisitions of mobile operators and other investments and our ability to incur and service debt. While depreciation and amortization are considered operating costs under generally accepted accounting principles, these expenses primarily represent the non-cash current period allocation of costs associated with long-lived assets acquired or constructed in prior periods. Our OIBDA calculation is commonly used as one of the bases for investors, analysts and credit rating agencies to evaluate and compare the periodic and future operating performance and value of companies within the wireless telecommunications industry. OIBDA can be reconciled to our consolidated statements of operations as follows:

2 Here and further, in the comparison of period to period results of operations, in order to analyze changes, developments and trends in revenues by reference to individual segment revenues, revenues are presented on an aggregated basis, which is revenues after elimination of intra-segment (between entities in the same segment) transactions, but before inter-segment (between entities in different segments) eliminations, unless accompanied by the word "consolidated". Amounts attributable to individual companies, where appropriate, are shown prior to both intra-segment and inter-segment eliminations.

3 Here and further, MTS and Comstar UTS OIBDA are shown on consolidated basis and differ from respective standalone OIBDA values owing to certain consolidation reclassifications.
