Operating income (EBITDA) fell to $140.8 million on sales of $1.04 billion. As a result, the operating margin rose nearly a point and a half to 13.6%, the company said. Net earnings fell 65.4% to $3.07 million. Prometeon attributed much of the sales decline to an exchange rate effect in Latin America. Prometeon Tyre CEO Giorgio Bruno noted the 2020 performance marks the completion of a turnaround process launched three years ago. During that time, the firm implemented several strategic initiatives that have made Prometeon "healthier, stronger and more resilient in an unprecedented scenario."
