TREX CO INC 10-Q

Item 5. Other Information Trex Company Named Among Top 50 U.S. Manufacturers By Industry Week. In July 2022, Trex was named by Industry Week magazine as one of the 50 Best U.S. Manufacturers. In its first year of eligibility, Trex ranked #6 on the exclusive annual ranking of top-performing manufacturing companies. Companies ranked on IW’s “50 Best” list are pulled from the Industry Week U.S. 500, an annual listing of the top 500 publicly held U.S. manufacturing companies based on revenue. The “50 Best” formula then examines profit margin, revenue growth and inventory over a three-year period, as well as return on assets and return on equity over a five-year timeframe, with the most recent numbers weighted most heavily.
