DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 (this “Post-Effective Amendment”) relates to the following Registration Statements on Form S-8 (each, a “Registration Statement” and collectively, the “Registration Statements”) of Alteryx, Inc., a Delaware corporation (the “Registrant”), which were previously filed by the Registrant with the U.S. Securities and Exchange Commission (the “SEC”) and is being filed to deregister any and all securities that remain unsold or otherwise unissued as of the date hereof under each such Registration Statement:

On March 19, 2024, pursuant to an Agreement and Plan of Merger, dated December 18, 2023, by and among Azurite Intermediate Holdings, Inc. (“Parent”), Azurite Merger Sub, Inc., a wholly owned subsidiary of Parent (“Merger Sub”), and the Registrant, Merger Sub merged with and into the Registrant, with the Registrant surviving as a wholly owned subsidiary of Parent (the “Merger”).

As a result of the Merger, the Registrant is terminating all offers and sales of its securities registered pursuant to the Registration Statements and deregistering the remaining shares of Class A common stock and Class B common stock (collectively, the “Shares”) registered but unsold as of the effective time of the Merger under the Registration Statements, if any. In accordance with an undertaking made by the Registrant in the Registration Statements to remove from registration, by means of a post-effective amendment, any of the Shares that had been registered for issuance under the Registration Statements that remain unsold at the termination of the offerings, the Registrant hereby removes from registration any and all such Shares registered but unsold as of the date hereof under the Registration Statements. The Registration Statements are hereby amended, as appropriate, to reflect the deregistration of such Shares as of the date hereof and the Registrant hereby terminates the effectiveness of the Registration Statements.
