Case Study

The Authority on PFAS

A Due Diligence Case Study

John Gardella was recently contacted by a group of private equity investors that had representatives from six of the country’s top ten private equity firms. In an invitation-only event, Attorney Gardella spoke to over fifty private equity representatives on the investment portfolio risks associated with PFAS to sectors such as manufacturing, industry, waste management, construction, utilities, and insurance. These risks are not widely understood, and Attorney Gardella was sought out for his expertise based on his years of thought leadership and due diligence advising about PFAS. As a result of the session, attendees from the event adjusted portfolio content to reduce risk from unforeseen PFAS concerns to investors, thereby strengthening the security of their equity offerings.
