NOTE 1—BUSINESS AND BASIS OF PRESENTATION

Business

Williams Industrial Services Group Inc. (together with its wholly owned subsidiaries, “Williams,” the “Company,” “we,” “us” or “our,” unless the context indicates otherwise) was initially formed in 1998 as GEEG Inc., a Delaware corporation, and in 2001 changed its name to “Global Power Equipment Group Inc.,” and, as part of a reorganization, became the successor to GEEG Holdings, L.L.C., a Delaware limited liability company. Effective June 29, 2018, the Company changed its name to Williams Industrial Services Group Inc. to better align its name with the Williams business, and the Company’s stock trades on the NYSE American LLC under the ticker symbol “WLMS.” Williams has been safely helping power plant owners and operators enhance asset value for more than 50 years. It provides a broad range of construction, maintenance, and support services to infrastructure customers in energy, power, and industrial end markets. The Company’s 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.

Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) on a basis consistent with that used in the Annual Report on Form 10-K for the year ended December 31, 2021, filed by the Company with the U.S. Securities and Exchange Commission (“SEC”) on March 16, 2022 (the “2021 Report”). In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, including all normal recurring adjustments, necessary to present fairly the unaudited condensed consolidated balance sheets and statements of operations, comprehensive income, stockholders’ equity and cash flows for the periods indicated. All significant intercompany transactions have been eliminated. The December 31, 2021 condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. These unaudited condensed consolidated interim financial statements and accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the 2021 Report. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year-end. The results of operations for any interim period are not necessarily indicative of operations to be expected for the full year.

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:
