MOSCOW--Russian state gas company OAO Gazprom (GAZP.RS) said Thursday that its net profit for the third quarter fell 10.8% compared to the same period last year due to higher operating expenses and a decline in finance income.

Gazprom said net profit for the quarter stood at 276.1 billion rubles ($8.1 billion). Revenue was up 7.4% to 1.2 trillion rubles.

Through the nine months ending Sept. 31, Gazprom's profits rose 3.8% compared to the same period in 2012, a year in which the company's profits slumped as sales in its key European markets dropped due to increased competition and lower demand. Through September, Gazprom says sales to Europe have increased 6.4% compared to the same period in 2012.
