MEMORANDUM OPINION AND ORDER Plaintiff Mark Michelson sued Defendants Accertify, Inc. (“Accertify”), American Express Company (“American Express”), and Mark Michelon, alleging Sarbanes-Oxley Act (“SOA”) retaliation (Count I), Consumer Financial Protection Act (“CFPA”) retaliation (Count II), and retaliatory discharge (Count III). [1]. Defendants now move for summary judgment. [36]. For the reasons explained below, this Court grants Defendants’ motion. I. Background1 Accertify, a provider in fraud risk mitigation, chargeback management, and digital identity solutions, constitutes a wholly owned subsidiary of American Express, a financial services corporation.2 [49] ¶¶ 1, 2. Plaintiff served as Director of

1 The Court draws these facts from Plaintiff and Defendant’s Rule 56.1 Statements of Facts [38], [48], including exhibits, and the parties’ responses thereto [49], [52], where supported.

2 In 2024, American Express sold Accertify to a private equity firm. [49] ¶ 4. Chargeback Onboarding at Accertify, where he was subject to American Express’ policies, procedures, and benefits plans. Id. ¶¶ 15, 16. In his role, Plaintiff generated code, worked with banks to address and remedy disputed charges, and reported to

Paul Mangino, Vice President of Client Success at Accertify and Vice President of Client Management at American Express. Id. ¶¶ 17, 19. Between 2014 and 2022, Plaintiff worked with Sasil Ripaldi, an employee of Strategic Impact Solutions, Inc. (“Stratis”), an Accertify vendor. Id. ¶ 20. In May 2022, Plaintiff learned Ripaldi received a job offer from another company and planned to resign from Stratis. Id. ¶ 21. Hoping to continue his working relationship with

Ripaldi, Plaintiff offered Ripaldi an open position at Accertify/American Express. Id. ¶ 22. Knowing his job offer paid less than Ripaldi’s competing offer, Plaintiff asked Mangino if Accertify/American Express could increase the compensation offer to Ripaldi. Id. Mangino told Plaintiff he could not. Id. Undeterred, Plaintiff, together with Stratis, devised a scheme to make up the difference in pay. Id. ¶ 23. Under the scheme, Ripaldi would collect her compensation from Accertify/American Express and monthly “bonus” payments from Stratis, which

Stratis would then bill back to Accertify/American Express. Id. To this end, Stratis sent Accertify/American Express a monthly invoice for services, which included Ripaldi’s bonus, labeled “Staff Support.” Id. ¶¶ 28, 29. Plaintiff approved each monthly invoice by email, and Stratis would then send each to Accertify for final approval and payment. In total, from July 2022, when the Ripaldi scheme started, through November 2022, Stratis paid Ripaldi $13,800.97. Id. ¶ 26. In February 2023, it became clear that Plaintiff believed these pass-through payments to Ripaldi would continue only through the end of 2022, while Ripaldi believed the payments would be made through June 2023. As a result, Plaintiff,

looking for help, confessed the scheme to Mangino. Id. ¶ 31. Alarmed by Plaintiff’s disclosure, Mangino in turn took the matter to Mark Michelon, President at Accertify and Vice President and General Manager at American Express. Id. ¶¶ 5, 33. On February 14, 2023, worried that Plaintiff’s billback scheme violated company policy, Michelon escalated the issue to Kelley Joy, then-Vice President Colleague Strategic Partner at American Express and part of the Colleague

Experience Group (“CEG”). Id. ¶ 34. The following day, on February 15, 2023, Joy discussed the scheme with Victor Ayala, manager of the Colleague Labor and Relations group (“CLR”), who said the Internal Audit Group (“IAG”) may need to be involved due to “potential fraud” in the scheme. Id. ¶ 35. That same day, Joy contacted Lavinel Lotrean, Director of Fraud and Special Investigations at American Express, who referred the issue to the IAG for investigation. Id. ¶ 36. In an unrelated matter, in April 2023, Plaintiff told Michelon and Mangino

that he believed an Accertify salesperson was “lying” to customers about the time it would take to implement Accertify’s chargeback solutions, and that he thought the conduct was “not right.” [52] ¶¶ 3, 7. Plaintiff was concerned that the actual implementation periods for Accertify’s chargeback solutions exceeded the timelines sales staff communicated to customers. Id. To investigate Plaintiff’s concerns, Michelon contacted the Accertify salesperson Plaintiff referenced, who denied promising or committing to specific timelines and acknowledged the fluidity of implementation schedules. [52] ¶ 11; [38-3] ¶ 30. Michelon concluded there was no basis to escalate Plaintiff’s concerns. Id.

Finding Plaintiff’s concerns to be unfounded, neither Mangino nor Michelon ever relayed Plaintiff’s timeline concerns up the chain of command in American Express. [49] ¶¶ 70, 73. Joy and the CLR also never learned of Plaintiff’s concerns over the course of the internal investigation. Id. ¶¶ 70–74; [52] ¶ 10. After American Express learned of Plaintiff’s concerns in his demand letter, a separate IAG investigation into the timeline concerns found Plaintiff’s allegations were

unsubstantiated. [49] ¶¶ 77–79. In May 2023, Michelon contacted colleagues at American Express and IAG to discuss the Stratis investigation, stating there was “some urgency to put the investigation to bed.” [52] ¶¶ 14, 15. Additionally, during Michelon’s June 13, 2023 interview with IAG, Michelon said he would “take opinion from the committee to stay consistent with the company” on IAG’s final recommendation as to Plaintiff, to which the investigator said, “it is ultimately your decision.” [49] ¶ 49; [52] ¶ 17. Michelon

responded, “we need to stay consistent.” [52] ¶ 17. On or around June 27, 2023, American Express’ CLR and CEG met to review the IAG investigation’s preliminary findings concerning Plaintiff’s billback scheme with Ripaldi. [49] ¶¶ 43–45. In this meeting, Joy, CLR, and CEG recommended that the company fire Plaintiff. Id. On July 17, 2023, Joy met with Mangino, informing him of CLR and CEG’s recommendation. Id. ¶ 48. Three days later, IAG issued its final report in which IAG “substantiated” concerns that Plaintiff approved the billback payments to Ripaldi to supplement her salary. Id. ¶ 51. IAG determined that Plaintiff “knowingly approved” the payments

to Ripaldi and “purposely did not disclose this arrangement.” Id. ¶ 52. Based upon these findings, IAG recommended Plaintiff be terminated. Id. On July 27, 2023, Mangino met with Plaintiff to tell him the company was terminating his employment. Id. ¶ 53. On October 2, 2024, Plaintiff sued, arguing that his termination violated the SOA, the CFPA, and Illinois law. See [1]. Defendants now seek summary judgment,

arguing that they remain entitled to judgment as a matter of law on all counts, [36]. II. Legal Standard Summary judgment may be properly granted where there is “no dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). A genuine dispute as to any material fact exists if “the evidence is such that a reasonable jury could return a verdict” in favor of the non-moving party. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248 (1986). The moving party bears
