#### MEMX EXECUTION SERVICES LLC Notes to Financial Statement December 31, 2024

#### **1. ORGANIZATION AND DESCRIPTION OF BUSINESS**

MEMX Execution Services LLC (the "Company" or the "broker-dealer") was organized as a Delaware Limited Liability Company on May 7, 2019. The Company is a subsidiary of MEMX Holdings LLC ("MEMX Holdings") and MEMX SubCo LLC ("MEMX SubCo"), with 99.5% and 0.5% ownership interests, respectively. MEMX SubCo is a wholly owned subsidiary of MEMX Holdings.

The Company was established to support its affiliate national securities exchange, MEMX LLC, ("MEMX LLC" or the "Exchange") by taking orders from the Exchange to be routed to other venues for execution. The broker-dealer was approved by the Financial Industry Regulatory Authority ("FINRA") on June 11, 2020 and began routing orders of equity securities on behalf of the Exchange on February 17, 2021. On June 13, 2023, FINRA approved the broker-dealer's continuing membership application to expand its business to routing of options orders on behalf of the Exchange. As of December 31, 2024, the broker-dealer has not begun routing options orders.

The company is a registered broker-dealer regulated by the Securities and Exchange Commission ("SEC"), FINRA, other self-regulatory organizations ("SROs") of which it is a member, and other federal and state agencies. FINRA is the Company's designated examining authority. The Company is subject to the SEC's net capital rule, which specifies minimum net capital levels for registered broker-dealers and is designed to enforce minimum standards for the financial condition and liquidity of broker-dealers. The Company does not hold customer funds or safekeep customer securities and it clears all transactions on a fully-disclosed basis through its clearing firm.

### **2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

#### **Basis of presentation**

The financial statement includes all accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"), following Accounting Standards Codification ("ASC") as set forth by the Financial Accounting Standards Board ("FASB").

### **Segment reporting**

The Company operates as one reportable operating segment, U.S. order routing services. The Company has identified its Chief Executive Officer as the chief operating decision maker ("CODM"), who uses net income and excess net capital, which is not a measure of profit and loss, to make operational decisions while maintaining capital adequacy and manage the Company. The Company's operations constitute a single operating segment and therefore, a single reportable segment, because the CODM manages the business activities using information of the Company as a whole.

#### **Use of estimates**

The preparation of the financial statement in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts and disclosure of contingent amounts in the financial statement and accompanying notes. Management believes the estimates used in preparing the financial statement are reasonable and prudent. Actual results could differ from these estimates.
