We have two reportable segments: the Southeast segment, and the Western segment.

The Southeast reporting segment, which is also an operating segment, is composed of sales from our manufacturing facilities in Florida. The Western reporting segment, also an operating segment, is composed of sales from our manufacturing facilities in Arizona, California and, with the Martin Acquisition, Utah.

Centralized financial and operational oversight, including resource allocation and assessment of performance on an income (loss) from operations basis, is performed by our CEO, whom we have determined to be our chief operating decision maker (“CODM”), with oversight by the Board of Directors.

The following table represents summary financial data attributable to our operating segments for the years ended December 31, 2022, January 1, 2022, and January 2, 2021. Results of the Southeast segment for the year ended January 1, 2022 includes the results of Eco for its post-acquisition period from February 1, 2021. Results of the Southeast segment for the year ended January 2, 2021 includes the results of NewSouth for its post-acquisition period from February 1, 2020.
