Myseum.AI Assigns Sales Agent Role to StoneX via Second Amendment

What Happened
Myseum.AI, Inc. (MYSE) announced on September 21, 2026 that it entered into a Second Amendment to its Sales Agreement, assigning The Benchmark Company, LLC’s obligations under the Sales Agreement to StoneX Financial Inc. The original Sales Agreement was dated February 10, 2025 and was previously amended on February 6, 2026. The company also filed Amendment No. 2 to its prospectus supplement on September 21, 2026 to reflect this assignment.

Key Details

• The Second Amendment assigns Benchmark’s rights, interests and obligations under the Sales Agreement to StoneX Financial Inc.
• All references to “The Benchmark Company, LLC” as the “Sales Agent” in the Sales Agreement are now deemed to refer to StoneX Financial Inc.
• StoneX Financial Inc. is an SEC-registered broker‑dealer and a member of FINRA and SIPC.
• The Second Amendment is filed as Exhibit 1.1 to the Form 8-K; the prospectus supplement was amended the same day (Amendment No. 2).

Why It Matters
This is an operational change to who will act as the sales agent under Myseum.AI’s at‑the‑market (ATM) or similar sales arrangement—StoneX will now handle the execution of sales that were previously handled by Benchmark. For investors, it does not, by itself, change the terms of the Sales Agreement or disclose new financing amounts; it simply documents the transfer of the sales-agent role to a different, registered broker‑dealer. Review the filed Second Amendment (Exhibit 1.1) and the updated prospectus supplement for full details.
