On October 4, 2023, the Department of Justice (DOJ) announced the advent of a new safe harbor for companies that discover wrongdoing by the acquired business in the course of an M&A transaction. Buyers hoping to take advantage of this avenue for leniency would be well-advised to conduct thorough diligence and act quickly to report any wrongdoing they uncover, as the potential upsides for those who do so may be considerable in light of the DOJ’s new policy.
