Morgan Stanley & Co. LLC 1585 Broadway New York, NY 10036 SEC-Required Report on Routing of Customer Orders For Quarter Ending March 31st, 2026 The Securities and Exchange Commission (“SEC” or “Commission”) Rule 606, as amended (the “Rule”) requires all brokerage firms to make publicly available quarterly reports that present a general overview of the Firm’s routing of non-directed customer orders in covered equity and option securities. Non-directed orders are orders that customers have not specifically instructed to be routed to a specific destination. For these non-directed orders, Morgan Stanley & Co. LLC (“Morgan Stanley”) has selected the execution venue on behalf of its customers. In addition, Morgan Stanley must identify the significant venues to which it routed customer orders for execution during the applicable quarter. To obtain information about the rule, you may access the following web site addresses: http://www.sec.gov/rules/final/34-43590.htm and http://www.sec.gov/interps/legal/mrslb13a.htm and https://www.sec.gov/rules/final/2018/34-84528.pdf and https://www.sec.gov/tm/faq-rule-606-regulation-nms. The report is divided into three sections: one for stocks included in the S&P 500 index; one for stocks not included in the S&P 500 index; and one for exchange-listed options. For each section, this report identifies the venues most often selected by Morgan Stanley, sets forth the percentage of various types of orders routed to the venues and associated fees and rebates. In addition, at the end of the report, there is a discussion of the material aspects, if any, of Morgan Stanley’s relationship with the venues and General Disclosure section that provides additional information relevant to Morgan Stanley’s order routing and handling practices. 1
