Wheel manufacturer Superior Industries International Inc. reported weaker-than-expected revenue and profitability for 2018 and we expect that its profitability will remain weak in 2019, causing its adjusted debt to EBITDA to remain above 5x. Therefore, we are revising our outlook on the company to negative from stable and are affirming our 'B' issuer credit rating. At the same time, we are affirming our 'B' issue-level rating on Superior's term loan and our 'B-' issue-level rating on its unsecured notes. Our '3' recovery rating on the term loan and '5' recovery rating on the unsecured notes remain unchanged. The negative outlook reflects our expectation that higher operating costs in North America and weaker demand could cause Superior's leverage to remain well
