Item 3.01  Notice or Delisting or Failure to Satisfy a Continued
Listing Rule or Standard; Transfer of Listing

     On February 10, 2010, NASB Financial, Inc. ("NASB" or the
"Company") filed a Form 12b-25, which stated that the Company was
unable to file timely its Form 10-Q for the quarter ended December 31,
2009, because more time is needed to complete an evaluation of its
investment in LLCs for possible impairment. The Company has an
investment in an LLC consisting of its 50% ownership interest in an
entity that was formed for the purpose of developing land for
residential real estate sales. Due to the economic downturn, sales of
lots have not met previous expectations. As a result, the Company is
evaluating its investment, which is accounted for using the equity
method of accounting, to determine if its investment is impaired.  The
Company's investment in the LLC, prior to any impairment, is
approximately $19 million at December 31, 2009.

     On February 17, 2010, NASB was notified by The NASDAQ Stock Market
of its non-compliance with Listing Rule 5250(c)(1), which requires the
timely filing of periodic financial statements.  The Company must
submit a plan to regain compliance no later than April 19, 2010.
Although NASB cannot predict with certainty when the Form 10-Q for the
quarter ended December 31, 2009 will be available, it expects that it
will be before April 19, 2010.

     The Company's press release dated February 19, 2010, relating to
the delay in filing its quarterly report on Form 10-Q for the quarter
ended December 31, 2009, is attached hereto as exhibit 99.1, and is
incorporated herein by reference.
