Production Highlights

In the first six months of 2012 KMG EP produced 6,057 thousand tonnes of crude oil (248 kbopd), including the Company's stakes in Kazgermunai (KGM), CCEL and PetroKazakhstan Inc. (PKI) which is 4% less than in the same period of 2011.

JSC Uzenmunaigas ("UMG") produced 2,467 thousand tonnes (100 kbopd), which is 266 thousand tonnes less than in the same period of 2011. JSC Embamunaigas ("EMG") produced 1,376 thousand tonnes (56 kbopd), which is 7 thousand tonnes less than in the same period of 2011. In total this represents 7% less than in the same period of 2011.

The major reasons for low production levels at UMG were adverse weather conditions in first quarter, effect of wells idle time accumulated during labor action in 2011, as well as deteriorating infrastructure and equipment.

Taking into account recent production trend and the results of the first half of the year, the Company updates its annual production plan for UMG, initially set at 5,800 thousand tonnes. According to preliminary estimates it is expected that UMG will produce about 5,000 thousand tonnes in 2012 (101 kbopd). The Company expects that EMG will achieve initial plan of 2,815 thousand tonnes (57 kbopd). Thus, it is expected that the total volume of the oil produced at UMG and EMG in 2012 will be about the same as in 2011. The modernisation program, which the Company has started in 2012, is intended to lay a foundation for sustainable and efficient production in the future.

The Company's share in the productions from KGM, CCEL and PKI for the six months of 2012 amounted to 2,215 thousand tonnes of crude oil (92 kbopd) or 1% more than in the same period of 2011. The 2012 Production plans of KGM, CCEL and PKI are not being revised.

Crude oil sales

In the first six months of 2012 the Company's export and domestic sales from UMG and EMG were 3,011 thousand tonnes (122 kbopd) and 960 thousand tonnes (39 kbopd) respectively. Thus, total volume of sales from UMG and EMG amounted to 3,970 thousand tonnes (161 kbobd), 5% less than in the same period of 2011.

The Company's shares in sales of crude oil from KGM, CCEL and PKI were 2,237 thousand tonnes (93 kbopd), including 1,530 thousand tonnes (64 kbopd) supplied to export. PKI sales volumes include sales of oil products as well.

Net Profit for the Period

Profit after tax (net income) in the first six months of 2012 was 121bn Tenge (US$820m), representing a 6% increase compared to the same period of 2011, mainly due to higher average sales prices for export and domestic supply and lower SG&A expenses, as well as foreign exchange gain partly offset by a decline in export volumes.

Revenues

The Company's revenues in the first six months of 2012 remained at similar levels to those of the same period of 2011, and amounted to 399bn Tenge (US$2,690m). The effect of the 33% increase in domestic selling prices was partly offset by reduced export volumes. Domestic supply prices were higher, according to the agreement with Government on increase of oil prices in 2012 as partial compensation for the increased costs at Uzen.

Taxes other than on Income

Taxes, other than on income, in the first six months of 2012 were 144bn Tenge (US$974m), which is 11% lower compared to the same period of 2011. The decrease is due to the reduced production and export volumes.

Production Expenses

Production expenses in the first six months of 2012 were 69bn Tenge (US$467m), which is 10% higher compared to the same period of 2011. A significant part of the production costs increase is due to the annual salary indexation applied from January 1, 2012 and the decrease in crude oil balance, which were partly offset by a reduction in repairs and maintenance expenses due to reduction of the number of repaired wells.

Selling, General and Administrative Expenses

Selling, general and administrative expenses in the first six months of 2012 were 47bn Tenge (US$318m), which is 21% lower compared to the same period of 2011. The decrease is mainly due to lower expenses for penalties and fines, lower management fees to National Company Kazmunaigas as well as lower transportation expenses as a result of lower transportation volumes, partially offset by an increase in employee costs.

Fines and penalties

On July 12, 2012 the Tax Committee of the Ministry of Finance of the Republic of Kazakhstan completed the 2006-2008 comprehensive tax audit of the Company. As a result of the tax audit, which was commenced in October 2011, the tax authorities provided a tax assessment to the Company of 16.9bn Tenge, including 5.8bn Tenge of principal, 7.2bn Tenge of administrative fines and 4.0bn Tenge of late payment interest. The Company has begun the process of preparing an appeal to the Court.

Cash Flows from Operating Activities

Operating cash flow in the first six months of 2012 was 91bn Tenge (US$612m), which is 5% higher compared to the same period of 2011, this is mainly due to higher average sales prices for export and domestic supply and lower selling, general and administrative expenses, partly offset by a decline in export volumes.

Capex

Income from associates and joint ventures

In the first six months of 2012, KMG EP's share in associates and joint ventures was 41bn Tenge (US$276m), 16% lower compared to the same period of 2011. This was mainly driven by decrease of export volumes and increase of tax payments, which was partially compensated by higher oil prices.
