On January 29, 2026, the US Department of Justice (DOJ) and
United States Postal Service announced a $1 million payment to a
whistleblower for reporting information about a criminal antitrust
violation. The payment is the first under the DOJ's and
Postal Service's new Whistleblower Rewards Program.
The announcement is reminder of the importance of conducting
comprehensive antitrust due diligence when engaged in mergers and
acquisitions (M&A), building antitrust compliance into
integration planning, and maintaining robust policies and
procedures to detect and prevent antitrust violations across the
enterprise.
