"Tower delivered solid financial results in the fourth quarter as revenue, adjusted EBITDA, adjusted EPS and free cash flow were all above our previous outlook," said CEO Jim Gouin.
"The Tower team did a great job throughout 2017, remaining focused on safety and quality, while meeting our customers' requirements and delivering impressive financial results. We continue to invest in Tower's growth, and are benefiting from the emerging industry trends, as demonstrated by the $350m of net new business backlog.
"This new business coupled with our exposure to trucks and SUVs in North America position Tower for continued growth in the coming years at a faster pace than the industry."
