UnitedHealth Group (UNH) and Amedisys (AMED) extended the deadline for closing their $3.3 billion merger agreement as the US Department of Justice scrutinizes the deal, a filing showed Friday.

Under a waiver agreement executed Thursday, the deadline is extended to 10 days after a final court decision is issued in the lawsuit filed by the Justice Department to block the proposed acquisition or on Dec. 31, 2025, whichever is earlier, the filing showed.

The new agreement includes a regulatory break fee of $275 million, which may go up to $325 million if the companies fail to divest certain assets to gain approval, according to the filing.

Amedisys' shares were up more than 3% in recent premarket activity and UnitedHealth shares were marginally advancing.
