Item 8.01 Other Events

On November 16, 2025, a subsidiary of Artisan Partners Asset Management Inc. (the “Company”), entered into a definitive purchase agreement (the “Purchase Agreement”) to acquire 100% of the issued and outstanding equity interests of Grandview Property Partners, LLC ( “Grandview”), a real estate private equity firm specializing in originating, developing, acquiring and managing middle market properties across the United States. Grandview currently manages approximately $940 million of institutional assets. The transaction is expected to close in the first quarter of 2026, subject to customary closing conditions.

The purchase price includes an upfront cash payment and contingent post-closing payments, which are primarily calculated in accordance with a formula based on capital raised in future funds sponsored by Grandview between the closing date and the seventh anniversary of the closing date. The contingent consideration is payable in cash.

The Company intends to use cash-on-hand to pay the purchase price and currently anticipates that the acquisition will have an immaterial impact on the Company’s 2026 financial condition and operating results. The Company expects that the acquisition will be mildly accretive to earnings per share after the final closing of Grandview’s next flagship closed-end draw down fund.

A copy of the press release issued by the Company on November 18, 2025, announcing the transaction is attached as Exhibit 99.1 hereto and is incorporated herein by reference.
