Edelman Financial Engines Lawsuit: Prime, Mariner, and Crypto Scam

The Edelman Financial Engines lawsuit landscape in 2026 centers on three matters: an active federal case against Prime Capital Investment Advisors in Delaware alleging a $1.5 billion advisor-poaching scheme, a June 2026 summary judgment loss against Mariner Wealth Advisors in Kansas, and a small client suit over a cryptocurrency scam that was sent to arbitration in July 2025.¹² Two of the three cases involve the same core question: whether departing financial planners and their new employers stole trade secrets, or simply competed. Courts have split on that question, and the Prime Capital trial in August 2026 is likely to sharpen the answer.

The Prime Capital Case

Edelman filed suit against Prime Capital Investment Advisors on November 19, 2025, in the U.S. District Court for the District of Delaware, naming Prime, its CEO Glenn Spencer, and its Director of M&A and Advisor Recruiting, Grant Spencer, as defendants.¹ The complaint alleges a multi-year conspiracy to recruit Edelman planners, extract confidential client data, and move roughly $1.5 billion in client assets to Prime.³

What Edelman Alleges

According to the complaint, Prime recruited 12 Edelman financial planners between 2023 and 2025 and planned to recruit as many as 40 more.⁴ Edelman says that after planners secretly agreed to join Prime, they were instructed to stay put and covertly harvest confidential client information from Edelman’s proprietary databases, using memorization and other methods designed to avoid detection.¹ Prime then allegedly coordinated the timing of resignations, having planners mail letters to distant Edelman offices before weekends or holidays to buy time for client solicitation.³

The Key Rulings

The case escalated in February 2026 when planners Joan Greenspon and Amanda Salyer resigned and joined Prime. Greenspon’s clients represented approximately $236.2 million in assets under management; Salyer’s about $69.7 million.⁵ Court filings later showed Prime paid Greenspon a $1.25 million “goodwill deposit” and Salyer a $750,000 upfront payment to make the switch.⁶

On March 12, 2026, Judge Maryellen Noreika granted a temporary restraining order in part, finding Edelman’s non-solicitation and confidentiality provisions likely enforceable under Delaware and Pennsylvania law. She barred Prime from using Edelman’s confidential information or soliciting former Edelman clients served by Greenspon and Salyer, but refused to enforce Edelman’s broader “non-acceptance” provisions, reasoning they would “prohibit consumers from accessing and working with a financial planner of their choice.”⁵

The picture shifted at the April 23, 2026 preliminary injunction hearing. Greenspon and Salyer had each submitted sworn declarations claiming they did not possess Edelman client data and had not solicited clients. Expedited discovery proved both claims false. Greenspon had photographed pages from Edelman’s password-protected Salesforce database showing individualized client assets, email addresses, and phone numbers. Salyer had handwritten a list of more than 200 Edelman clients organized by descending assets under management and given it to Prime. When Salyer said she “did not initially think that AUM was financial information,” the court called that claim “hard to believe” for a financial planner. Both were impeached multiple times when their sworn declarations contradicted their deposition testimony.⁶

On May 21, 2026, Judge Noreika converted the TRO into a preliminary injunction. This time she upheld both the non-solicitation and the broader non-acceptance provisions, enforcing Greenspon’s 15-month non-solicitation and non-acceptance period and Salyer’s 12-month non-solicitation and 18-month non-acceptance period.⁶ The court observed that Prime appeared to view the cost of potential litigation and settlements as more economically rational than competing honestly.⁷ Glenn Spencer had testified that AUM is not public information and told the court, “I don’t like the fact that AUM was taken.”

Where the Case Stands

A second temporary restraining order granted on May 11, 2026, imposed broader restrictions: Prime cannot contact clients serviced by any future Edelman planners who leave for Prime, must relinquish all Edelman confidential information, and must confer with Edelman before sending client notices.⁸ Discovery is active, and Prime has filed a motion to dismiss portions of Edelman’s claims.⁹ An expedited jury trial of up to five days is scheduled to begin August 3, 2026.¹⁰

The Mariner Wealth Advisors Case

Edelman brought a similar trade secrets suit in 2023 against Mariner Wealth Advisors, based in Overland Park, Kansas, alleging Mariner lured away 10 Edelman planners between 2021 and 2023, costing Edelman at least 851 clients and more than $621 million in managed assets.¹¹ Edelman claimed the departing advisors improperly took client lists and that Mariner’s CEO, Marty Bicknell, personally solicited at least one Edelman advisor.²

On June 8, 2026, U.S. District Court Judge Holly L. Teeter granted summary judgment to Mariner and dismissed the case entirely. She held that the partial client lists taken by the departing planners did not qualify as trade secrets under the Defend Trade Secrets Act. The advisors had used the “mere memory of their clients’ names” and gathered contact information from public sources, which she found does not amount to protected trade secrets.¹² Client-specific financial data such as account values and fees came to Mariner from the clients themselves when they moved their accounts.¹¹ There was no evidence Mariner directed new hires to bring client data.²

Judge Teeter warned that ruling for Edelman would create a “slippery slope” that could “potentially federalize every restrictive covenant case.” Unusually, she also admonished Edelman’s legal team for improper briefing tactics, including failure to cite the record properly, misrepresenting evidence, and allowing a corporate representative to submit an unauthorized, altered errata sheet to his deposition testimony.¹¹ Mariner had argued the suit was intended as a “chilling public message” to “stifle fair competition.”²

Edelman said it “respectfully disagrees with the court’s decision” and intends to “continue to pursue our claims,” signaling a possible appeal, though no appeal filing had been publicly reported as of mid-June 2026.²

The Crypto Scam Case: Maksumova v. Edelman

In the one case where Edelman is the defendant, former CVS Pharmacy employee Stella Maksumova filed suit in July 2025 in the U.S. District Court for the Eastern District of New York, alleging Edelman failed to stop her from liquidating her IRA to invest in a cryptocurrency scam called “Sluntrades.” Her total losses came to roughly $802,000, including $87,351 from the IRA liquidation.¹³ The complaint accused Edelman of “legitimizing illicit, fraudulent transactions” and said the firm knew or should have known the recommendation to liquidate was unsuitable.¹⁴ The case was referred to arbitration on July 22, 2025, and dismissed by the court two days later.¹⁵

About the Firm

Edelman Financial Engines is among the largest independent registered investment advisory firms in the country, serving approximately 1.3 million clients across more than 144 locations, with over $293 billion in assets under management as of the end of 2024.¹⁶ The firm is led by CEO Ralph Haberli. Founder Ric Edelman transitioned to a strategic advisory role and remains on the board but is not a party in any of these lawsuits.¹⁷

Edelman’s aggressive litigation over restrictive covenants has produced mixed results so far. In Delaware, courts have largely credited its scheme allegations against Prime and enforced its non-solicitation and confidentiality clauses. In Kansas, the same theory against Mariner failed outright, with the judge concluding that an advisor’s memory of client names is not a protectable trade secret. How the Prime Capital jury sees the same core question in August 2026 will matter well beyond these two firms.
