John's Ethical Dilemma in Conflict of Interest

John, a financial analyst at Wealth Management Corp, has been working on a significant project involving the assessment of potential investment opportunities for high-net-worth clients. During his analysis, he discovers that one of the potential investments is linked to a company that his firm has a contentious relationship with due to previous disputes over fees and services. Additionally, John has a personal investment in the company that could benefit from the project’s positive outcome.

He justifies his decision by stating that he believes his analysis was thorough and objective. What should John do in order to uphold his responsibilities to his employer?
