WARRENVILLE, Ill. — Navistar and Ford have ended litigation against each other and also terminated their current diesel engine supply agreement, but will continue to collaborate on other initiatives, the companies reported this week.

“Navistar and Ford benefitted from a successful partnership that provided value to both companies for nearly three decades. However, it’s in our best interests to resolve our conflict and continue our relationship with each other in other areas,” said Dan Ustian, Navistar chairman, president and chief executive officer. “The next phase of our relationship is consistent with Navistar’s strategy to diversify our customer base, while continuing to provide value to both companies through our existing joint ventures and our supply agreement in South America.”

“We are pleased to have reached an agreement with Navistar that we believe is in the best interest of both companies,” added Mark Fields, Ford’s president of The Americas. “This agreement comprehensively addresses our business relationship with Navistar and will help both companies focus on meeting the needs of our current and future truck customers.”
