BUSINESS AND ORGANIZATION

NOTE 1—BUSINESS AND ORGANIZATION

Effective June 29, 2018, Global Power Equipment Group Inc. changed its name to Williams Industrial Services Group Inc. (together with its wholly owned subsidiaries, “Williams,” the “Company,” “we,” “us” or “our,” unless the context indicates otherwise) to better align its name with the Williams business, and its stock trades on the NYSE American LLC (the “NYSE American”) under the ticker symbol “WLMS.” Williams has been safely helping plant owners and operators enhance asset value for more than 50 years. It provides a broad range of construction, maintenance, and support services to customers in energy, power, and industrial end markets. Williams’ mission is to be the preferred provider of construction, maintenance, and specialty services through commitment to superior safety performance, focus on innovation, and dedication to delivering unsurpassed value to its customers. The Company’s corporate headquarters are located in Atlanta, Georgia.

The Company reports on a fiscal quarter basis utilizing a “modified” 5-4-4 calendar (modified in that the fiscal year always begins on January 1 and ends on December 31). However, the Company has continued to label its quarterly information using a calendar convention. The effects of this practice are modest and only exist when comparing interim period results. The reporting periods and corresponding fiscal interim periods are as follows:
