Investors apparently complained about securities broker Mark Andrew MacArthur [CRD: 2411397, Newhall, California], given the publicly available information found on Financial Industry Regulatory Authority (FINRA) BrokerCheck. MacArthur worked for Ausdal Financial Partners Inc. from November 1, 2006, to November 1, 2023, was affiliated with Criterion Wealth Management from January 2008 to August 2017, and joined M2 Financial LLC since June 2017. See the following information to discover more about disclosures involving MacArthur.

Ausdal Financial Partners Investor Alleged Unsuitable Recommendations And Failure To Supervise

Specifically, on April 15, 2026, an Ausdal Financial Partners Inc. client filed FINRA Arbitration No. 26-00776 about Mark MacArthur. Primarily, the client alleged that MacArthur made unsuitable recommendations. There was supposedly inadequate supervision involving private placements purchased by the client's late spouse and investments held in an advisory account. Because of this, the client allegedly sustained damages involving complex exchange-traded funds (ETFs) and private placements. Therefore, the client requested up to $500,000 in compensation from Ausdal Financial Partners Inc. or MacArthur. BrokerCheck indicates that this arbitration is awaiting a resolution.

Mark MacArthur Sanctioned By United States Securities And Exchange Commission For Alleged Breach Of Fiduciary Duty

Additionally, the United States Securities and Exchange Commission issued Case No. 2:20-cv-01402 on July 3, 2023, sanctioning MacArthur. Allegedly, MacArthur breached his fiduciary duty by failing to disclose compensation arrangements and conflicts of interest tied to recommendations of private placement funds. The SEC also alleged violations of Sections 206(1) and 206(2) of the Investment Advisers Act of 1940. As a result, MacArthur was ordered to pay disgorgement of $231,948 and a civil penalty of $111,614. A final judgment was entered on July 3, 2023.

According to the SEC, MacArthur and other defendants allegedly recommended that advisory clients invest more than $16 million in four private placement funds between 2014 and 2017. They allegedly received more than $1 million in additional compensation from fund managers. Regulators alleged that these compensation arrangements were not adequately disclosed and created conflicts of interest because the compensation depended on clients remaining invested in the funds. The SEC further alleged that clients were not fully informed about these arrangements and that certain regulatory filings were misleading.
