ALMATY, May 5 (Reuters) - The Kazakh subsidiary of Russia's Sberbank (SBER03.MM) said on Wednesday expansion costs would push its 2010 profit below last year's $15.7 million.

"We expect a lower profit than the one we made in 2009," the chief executive of the Kazakh unit Oleg Smirnov told reporters.
