**Item 1. Security and Issuer**

**(a) Title of Class of Securities:**
Class A Common Stock, $0.01 par value per share

**(b) Name of Issuer:**
Artisan Partners Asset Management Inc.

**(c) Address of Issuer's Principal Executive Offices:**
875 E. Wisconsin Avenue, Suite 800, Milwaukee, WI, 53202

This Amendment No. 21 to Schedule 13D ("Amendment No. 21") amends the statement on Schedule 13D relating to the Class A common stock of Artisan Partners Asset Management Inc. (the "Company") filed by the Reporting Persons with the Securities and Exchange Commission on March 12, 2014, as amended from time to time (the "Schedule 13D").  Capitalized terms used in this Amendment No. 21 but not otherwise defined herein have the meanings given to them in the Schedule 13D.

This Amendment No. 21 is being made to report a decrease in the number of shares subject to the Stockholders Agreement described in the Schedule 13D and the percentage of the combined voting power attributed to those shares. Except as otherwise set forth herein, this Amendment No. 21 does not modify any of the information previously reported by the Reporting Persons in the Schedule 13D.

**Item 4. Purpose of Transaction**

Each Reporting Person may from time to time sell shares of Class A common stock (including, for Mr. Colson and Mr. Daley, shares of Class A common stock received upon exchange of the corresponding Class B common units and Class B common stock) over which the Reporting Person has sole dispositive power.  Shares subject to the Stockholders Agreement over which the Reporting Persons do not have dispositive power may also be sold from time to time by the owners of those shares.  Each Reporting Person may purchase additional shares of the Company's common stock or receive additional shares from the Company from time to time.  The Company may also issue shares to other employees of the Company over which the Stockholders Committee will have voting power pursuant to the Stockholders Agreement.  Any shares issued by the Company to employees (including the Reporting Persons) will be subject to the Stockholders Agreement.

Each of the Reporting Persons is an officer, and Mr. Colson and Mr. Gottlieb are also directors, of the Company.  In those capacities, the Reporting Persons may participate from time to time in discussions and planning with respect to transactions, events or actions set forth in subsections (a) through (j) of Item 4 of Schedule 13D.  The Reporting Persons reserve the right to formulate plans or make proposals, and take such action with respect thereto, including any or all of the items set forth in subsections (a) through (j) of Item 4 of Schedule 13D and any other actions, as they may determine.

**Item 5. Interest in Securities of the Issuer**

**(a)**
As of December 31, 2025, 6,138,834 shares of Class A common stock of the Company and all 1,137,929 shares of Class B common stock of the Company are subject to the Stockholders Agreement (the "Covered Shares"). Those shares, in the aggregate, represent 10.2% of the combined voting power of the Company's outstanding common stock as calculated in accordance with Rule 13d-3(d)(1)(i). Each of the Reporting Persons is a member of the three-person Stockholders Committee that has the power to vote the Covered Shares. As a result, each of the Reporting Persons may be deemed to have acquired beneficial ownership of all Covered Shares.  Each of the Reporting Persons disclaims beneficial ownership of all Covered Shares, except for those shares with respect to which each Reporting Person, respectively, possesses sole dispositive power as indicated on such Reporting Person's cover page to this Schedule 13D.  The Stockholders Agreement is described in greater detail in, and filed as an exhibit to, the Schedule 13D.

The percentage of outstanding common stock represents each Reporting Person's aggregate number of shares of Class A common stock beneficially owned, divided by the sum of the total number of outstanding shares of Class A common stock and the number of shares of Class A common stock that would be issued upon exchange of the shares of Class B common stock deemed to be beneficially owned by the Reporting Person.  Each share of Class B common stock corresponds to a Class B common unit of Holdings, which, together with the corresponding Class B common unit, is exchangeable for one share of Class A common stock, subject to certain restrictions and conditions.

**(b)**
The number of Covered Shares each Reporting Person has sole or shared voting or dispositive power of is set forth on such Reporting Person's cover page to this Schedule 13D.

**(c)**
None of Mr. Colson, Mr. Daley, nor Mr. Gottlieb transacted in Covered Shares in the 60 days prior to the filing of this Amendment No. 21.
