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

     On May 11, 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 March 31, 2010, because more
time is needed to complete an evaluation of its investment in LLCs for
possible impairment.  Additionally, the Company has been unable to file
its Form 10-Q for the quarter ended December 31, 2009, due to this
issue.  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.  Sales of lots have
not met previous projections. As a result, the Company is evaluating
its investment, which is accounted for using the equity method of
accounting, to determine whether the investment is impaired.  The
Company's investment in the LLC, prior to any impairment, is
approximately $19 million at March 31, 2010.

     On May 12, 2010, NASB was notified by The NASDAQ Stock Market that
it remains in non-compliance with Listing Rule 5250(c)(1), which
requires the timely filing of periodic financial statements.  The
Company must submit an update to its original plan to regain compliance
no later than May 27, 2010.

     The Company's press release dated May 17, 2010, relating to the
delay in filing its quarterly report on Form 10-Q for the quarter ended
March 31, 2010, is attached hereto as exhibit 99.1, and is incorporated
herein by reference.
