Description of Business Operations The Company provides mission-critical environmental and maintenance services to the power generation industry, enabling our customers to address challenges related to the remediation of coal ash ponds and landfills at open and closed power plant sites while continuously operating and providing necessary electric power to communities nationwide. Services offered include a suite of coal ash management and recycling, environmental remediation, and outage maintenance services. The Company also designs and implements solutions for complex environmental projects (such as coal ash pond closures) and facilitates coal ash recycling through byproduct sales and other beneficial use services. The Company has corporate offices in Kentucky, North Carolina, and Louisiana, and principally operates in the eastern and mid-central United States. Under the Jumpstart Our Business Startups Act (the “JOBS Act”), the Company meets the definition of an “emerging growth company,” which allows the Company to have an extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act. The Company intends to take advantage of all of the reduced reporting requirements and exemptions, including the longer phase-in periods for the adoption of new or revised financial accounting standards under Section 107 of the JOBS Act until the Company is no longer an emerging growth company. Among other things, we are not required to provide an auditor attestation report on the assessment of the internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act of 2002 and our disclosure obligations regarding executive compensation may be reduced. We may take advantage of these provisions until the last day of our fiscal year following the fifth anniversary of the IPO, or December 31, 2023. However, if certain events occur prior to the end of such five-year period, including if we become a “large accelerated filer,” our annual gross revenue exceeds $1.07 billion, or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-year period. Basis for Presentation The Company’s fiscal year ends December 31. The accompanying unaudited condensed consolidated financial statements include the assets, liabilities, stockholders’ equity and results of operations of the Company and its consolidated subsidiaries. Intercompany transactions and balances have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with rules and regulations of the Securities and Exchange Commission for quarterly reports on Form 10-Q. In the opinion of management, all adjustments considered necessary for a fair presentation have been included, which consist of normal recurring adjustments. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated and combined financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2019. Seasonality of Business Based on historical trends, we expect our operating results to vary seasonally. Nuclear power generators perform turnaround and outages in the off-peak months when demand is lower and generation capacity is less constrained. As a result, our nuclear services offerings may have higher revenue volume in the spring and fall months. Variations in normal weather patterns can also cause changes in the consumption of energy, which may influence the demand and timing of associated services for our fossil services offerings. Inclement weather can impact construction-related activities associated with pond and landfill remediation, which affects the timing of revenue generation for our remediation and compliance services. Our byproduct sales are also seasonally impacted during winter months when the utilization of cement and cement products is generally lower. Business Combinations On March 30, 2018, Charah Management completed a transaction with SCB Materials International, Inc. and affiliated entities (“SCB”), a previously unrelated third party, pursuant to which Charah Solutions acquired certain assets and liabilities of SCB for a purchase price of $35,000, with $20,000 paid at closing and $15,000 to be paid over time in conjunction with certain performance metrics. The contract also contained various mechanisms for a working capital true-up. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations with the allocation of the purchase price for the acquisition finalized as of March 31, 2019 with the recognized goodwill allocated to the Environmental Solutions segment. In November 2018, the $15,000 to be paid over time was reduced by $3,300. As of March 31, 2020, the present value of these future payments using a discount rate of 2.50% was determined to be $11,538. The Company expects the future payments to occur in 2021 and beyond.
