Our firm is investigating the AMPAM Parks Mechanical Employee Stock Ownership Plan (ESOP) regarding a potential multi-million-dollar loss to the ESOP and the retirement savings of employees.

In 2019, AMPAM’s owners sold 100% of the company to its employees through the ESOP. Based on publicly available documents that AMPAM filed with the Department of Labor, the ESOP paid $247 million for the company, but by the end of the same year the company was worth less than 10% of the purchase price.

If you participated in the AMPAM ESOP, your retirement savings may have been affected by the ESOP transaction and any losses resulting from the transaction.  If you are interested in learning more about this investigation, please complete the questionnaire below and we will contact you soon. You may also call or email us directly. Submission of this form is for the purposes of inquiry only and does not create a binding attorney/client relationship.

Cohen Milstein recognizes the importance of your privacy and personal data. Information collected in this questionnaire is confidential and will not be shared or sold.
