Nathan Warwick: Merrill Lynch Advisor Receives Suitability Complaint

Phoenix, Arizona financial advisor Nathan Warwick (CRD# 6942391) recently received an investor complaint alleging that he violated industry rules, leading to damages. Financial Industry Regulatory Authority records show that he is registered as a broker and an investment advisor with Merrill Lynch.

Mr. Warwick’s BrokerCheck report discloses one investor complaint. Filed in July 2026, it alleges that as a representative of Merrill Lynch, he made unsuitable investment recommendations and failed in his supervisory duties. The pending complaint alleges unspecified damages.

For reference, FINRA Rule 3010 required that member firms “establish and maintain a system to supervise the activities of each registered representative, registered principal, and other associated person that is reasonably designed to achieve compliance with applicable securities laws and regulations.” It has been superseded by FINRA Rule 3110, which similarly requires firms to “establish and maintain a system to supervise the activities of each associated person that is reasonably designed to achieve compliance with applicable securities laws and regulations, and applicable FINRA rules.” Section 20(a) of the Securities Exchange Act, meanwhile, makes individuals or entities liable for the actions of persons under their control, potentially making supervisory and management personnel at broker-dealer firms liable for the misconduct of representatives under their management.

According to the Financial Industry Regulatory Authority, Nathan Warwick holds eight years of securities industry experience. Based in Phoenix, Arizona, he has been registered as a broker and an investment advisor with Merrill Lynch since 2018. His credentials include the passage of three securities industry qualifying exams: the Securities Industry Essentials Examination, or SIE; the General Securities Representative Examination, or Series 7; and the Uniform Combined State Law Examination, or Series 66. He holds 38 state licenses. (Information current as of September 19, 2026.)
