Alafco was suing the U.S. planemaker for $336 million over accusations it wrongly refused to return advance payments on a cancelled order for 40 of its troubled 737 MAX planes.
The Kuwaiti lessor will now buy 20 aircraft from Boeing, instead of 40, with new delivery dates, it said in a bourse filing.
Additional details of the agreement could not be disclosed due to confidentiality clauses, it said.
Alafco said it was “looking forward to a long-lasting and mutually beneficial relationship with Boeing.”
Alafco and Boeing did not immediately respond to emailed requests for comment.
Boeing suspended deliveries of its narrow-body 737 MAX jet in March last year, when the Federal Aviation Administration grounded the aircraft after the deaths of 346 people in crashes of two 737 MAX planes operated by Lion Air and Ethiopian Airlines.
The crisis over the grounding of the once top-selling 737 MAX has cost the U.S. planemaker more than $19 billion, slashed production and hobbled its supply chain, with criminal and congressional investigations still ongoing.
Alafco’s owners include Kuwait Finance House (KW:KFH), Gulf Investment Corporation and state airline Kuwait Airways, according to its website.
