Perella Weinberg Partners (PWP) filed an 8-K dated September 1, 2026 announcing it has filed a prospectus supplement to its effective registration statement on Form S-3ASR (File No. 333-289189). The supplement covers the resale, from time to time, by certain existing stockholders of 1,127,529 shares of the company’s Class A common stock, par value $0.0001 per share. A legal opinion from Mayer Brown LLP regarding the legality of the shares is attached as Exhibit 5.1.

Key Details

• 1,127,529 shares of Class A common stock are covered by the prospectus supplement for resale by certain stockholders.
• Registration statement: Form S-3ASR, File No. 333-289189.
• Legal opinion of Mayer Brown LLP is attached as Exhibit 5.1; Mayer Brown’s consent is included (Exhibit 23.1 included within Ex. 5.1).
• 8-K filed and signed by Alexandra Gottschalk, CFO and COO, dated September 1, 2026.

Why It Matters
This filing enables certain stockholders to resell up to 1,127,529 shares under the company’s existing registration statement, which can increase available float and improve liquidity for those holders. Because the filing registers resale by holders (not a new issuance by the company), it is non-dilutive to existing shareholders’ ownership percentages, but could affect supply dynamics in the market if those shares are sold. The attached legal opinion confirms procedural legality, which can speed the resale process for the selling holders.
