PART II - RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)

      ý   (a)The reason described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense   (b)The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and   (c)The accountant's statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.  

PART III - NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

The Quarterly Report on Form 10-Q for period ended September 30, 2006 ("Form 10-Q") of Stifel Financial Corp. (the "Company") cannot be filed within the prescribed time period because additional time is necessary to amend the Form 10-K for the year ended December 31, 2005 ("Form 10-K"), which the Company believes should be filed prior filing the Form 10-Q. The Form 10-K amendment relates to unaudited pro forma financial information contained in the notes to consolidated financial statements. The aforementioned changes to the consolidated financial statements have no effect on the Company's consolidated statement of financial condition as of December 31, 2005 and 2004, or its consolidated statements of operations, stockholders' equity, and cash flows for each of the three years ended December 31, 2005. In addition, the amendment of Form 10-K has no effect on the Form 10-Q condensed consolidated financial statements as of and for the periods ending September 30, 2006. The Company expects to file its Form 10-Q no later than November 14, 2006.
