FOR IMMEDIATE RELEASE:
NASB Financial, Inc. Announces Financial Results

     Grandview, Missouri (February 5, 2007) - NASB Financial, Inc. (NASDAQ:
NASB) announced today net income for the quarter ended December 31, 2006, of
$4,574,000 or $0.55 per share.  This compares to net income of $5,666,000 or

net income of $5,209,000 or $0.62 per share for the quarter ended December
31, 2005.  The decrease in earnings for the quarter ended December 31, 2006,
was primarily the result of continued pressure on the net interest margin

quarterly dividend on common stock of $0.225 per share.  During the quarter
