Dear Mr. Rodriguez:

Stifel Financial Corp. (the “Company”) is submitting this letter in response to the comment communicated by the Staff of the Securities and Exchange Commission (the “Commission”) during a phone conversation between the Staff and the Company on July 20, 2016 and July 25, 2016, respectively, related to the Company’s disclosures in its Form 8-K filed on February 23, 2016.

The Staff’s verbal comments are included in this letter and are followed by the Company’s responses.

Staff Verbal Comment:

Form 8-K filed February 23, 2016

We believe your full condensed non-GAAP reconciliation is inconsistent with Section 102.10 of the updated Compliance and Disclosure Interpretation issued on May 17, 2016. Please review this guidance when preparing your next earnings release.

Response:

We acknowledge the Staff’s comment and we have revised the Company’s reconciliation of its GAAP to non-GAAP results beginning with our earnings release for the quarter ended June 30, 2016, filed with the Commission on August 2, 2016. We believe the revised reconciliation of the Company’s GAAP to non-GAAP results is consistent with the guidance in Section 102.10 of the updated Compliance and Disclosure Interpretation issued on May 17, 2016.
