This registration statement shall also cover any additional shares of common stock, par value $0.01 per share (the "Common Stock"), of the registrant which become issuable with respect to the shares of Common Stock registered hereunder for issuance under the Piper Sandler Companies Amended and Restated 2003 Annual and Long-Term Incentive Plan (as amended and restated May 17, 2023) by reason of any stock dividend, stock split, recapitalization or other similar transaction effected without the registrant's receipt of consideration which results in an increase in the number of the outstanding shares of Common Stock.

Note 1b. Estimated solely for purposes of calculating the registration fee, pursuant to Rule 457(h) and Rule 457(c), based on the average of the high and low sale prices per share of Common Stock on May 18, 2026, as reported on the New York Stock Exchange.
