History

Encore Wire began its legacy in 1989 as a 68,000 square foot industrial warehouse building in McKinney, Texas. It grew to over 3.5 million square feet under roof across 460 acres. The company held its Initial Public Offering on NASDAQ under the ticker WIRE in 1992. In 1994 it expanded its product line into commercial wire and added Plant 2. It added a Distribution Center in 1997, a Copper Rod Mill in 1998, and a Plastic Mill and railroad in 1999. In 2001 it expanded its product line again, adding Plant 3 for circuit wire (THHN, MTW & Striping). It expanded the distribution center to 420,000 sq. ft. and 60 dock doors in 2004, added Plant 4 for armored cable in 2006, added a Corporate Headquarters in 2007, and added Plant 5 for industrial cable in 2008. In 2010 Encore TechLab was born as a LEED Platinum Certified R&D Center, described as the first of its kind in North Texas. In 2012 it added Plant 6 and introduced aluminum building wire. It expanded its aluminum plant by 225,000 sq. ft. in 2014 and its armored cable plant by 161,000 sq. ft. in 2016. In 2021 it built a new 720,000 sq. ft. Service Center, and in 2022 converted the previous Distribution Center into Plant 7, a 421,500 sq. ft. commercial and industrial plant, and opened an Employee Center with an expanded on-site medical clinic.
