The U.S. Justice Department offered Boeing a plea deal on Sunday after it reportedly prepares to criminally charge the company of violating a 2021 deferred prosecution agreement that was implemented after two 737 Max crashes in 2018 and 2019.

The Justice Department told Boeing it could plead guilty or go to trial, according to reports.

Under the proposed agreement, if Boeing pleads guilty to a conspiracy charge, it would pay a fine and enter a three-year probationary period where an independent monitor would conduct an audit.
