BUSINESS AND BASIS OF PRESENTATION
BUSINESS AND ORGANIZATION	NOTE 1—BUSINESS AND ORGANIZATIO N 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: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Reporting Interim Period ​ Fiscal Interim Period ​ 2022 2021 Three Months Ended March 31 ​ January 1, 2022 to April 3, 2022 ​ January 1, 2021 to April 4, 2021 Three Months Ended June 30 ​ April 4, 2022 to July 3, 2022 ​ April 5, 2021 to July 4, 2021 Three Months Ended September 30 ​ July 4, 2022 to October 2, 2022 ​ July 5, 2021 to October 3, 2021 ​

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2022
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES.
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 3—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Joint Ventures: In 2017, the Company formed a limited liability company (“LLC”) with an unrelated third party for the execution of a nuclear plant construction project. The Company has a 25 percent participation interest in this LLC, with distribution of expected gains and losses being proportionate to its participation interest. Although the LLC holds the construction contract with the client, the services required by the contract are performed by either the LLC, the Company, or the other member of the LLC, or by other subcontractors under subcontracting agreements with the LLC. The Company accounts for its investment in this LLC using the equity method. The Company’s investment in this LLC was $1.9 million and $2.5 million as of December 31, 2022 and 2021, respectively, and was included in other long-term assets on the consolidated balance sheets. Accounts receivable related to work performed for the Company’s unconsolidated investment in the LLC, included in accounts receivable, net, on the consolidated balance sheets, was $4.8 million and $4.6 million as of December 31, 2022 and 2021, respectively. The Company’s pro-rata share of net income from the LLC was $0.2 million and $0.7 million for the years ended December 31, 2022 and 2021, respectively, and was included in other (income) expense, net, on the consolidated statements of operations. In addition, the Company received a dividend in 2022 of $0.8 million for the period ended December 31, 2021 but did not receive a dividend for the period ended on December 31, 2022. Discontinued Operations: On July 11, 2018, Koontz-Wagner filed a voluntary petition for relief under Chapter 7 of Title 11 of the Bankruptcy Code with the U.S. Bankruptcy Court for the Southern District of Texas. The filing was for Koontz-Wagner only, not for the Company as a whole, and was completely separate and distinct from the Williams business and operations. Unless otherwise specified, the financial information presented in the accompanying financial statements and following notes relates to the Company’s continuing operations; it excludes any results of its discontinued operations. For additional information, please refer to “Note 5—Changes in Business” for financial information on the Company’s discontinued operations. Segment and Geographic Information The Company uses operating income (loss) to compare and evaluate its financial performance. For the year ended December 31, 2022, the Company earned 97.7% and 2.3% of its revenue in the U.S. and Canada, respectively. For the year ended December 31, 2021, the Company earned 88.1% and 11.9% of its revenue in the U.S. and Canada, respectively. Use of Estimates: Revenue Recognition: The Company’s contracts generally include a single performance obligation for which revenue is recognized over time, as performance obligations are satisfied, due to the continuous transfer of control to the customer. For cost-plus contracts, the Company recognizes revenue when services are performed and contractually billable based upon the hours incurred and agreed-upon hourly rates. Revenue on fixed-price contracts is recognized and invoiced over time using the cost-to-cost percentage-of-completion method. To the extent a contract is deemed to have multiple performance obligations, the Company allocates the transaction price of the contract to each performance obligation using its best estimate of the standalone selling price of each distinct good or service in the contract. The Company does not adjust the price of the contract for the effects of a significant financing component. Change orders are generally not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as a modification of the existing contract and performance obligation. The Company believes these methods of revenue recognition most accurately reflect the economics of the transactions with its customers. The Company’s contracts may include several types of variable consideration, including change orders, rate true-up provisions, retainage, claims, incentives, penalties, and liquidated damages. The Company estimates the amount of revenue to be recognized on variable consideration using estimation methods that best predict the amount of consideration to which the Company expects to be entitled. The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based on an assessment of its anticipated performance and all information (historical, current, and forecasted) that is reasonably available. The Company updates its estimate of the transaction price each reporting period and the effect of variable consideration on the transaction price is recognized as an adjustment to revenue on a cumulative catch-up basis. In circumstances where the Company cannot reasonably determine the outcome of a contract, it recognizes revenue over time as the work is performed, but only to the extent of recoverable costs incurred (i.e., zero margin). A loss provision is recorded for the amount of any estimated unrecoverable costs in excess of total estimated revenue on a contract as soon as the Company becomes aware. The Company generally provides a limited warranty for a term of two years or less following completion of services performed under its contracts. Historically, warranty claims have not resulted in material costs incurred. During the year ended December 31, 2022, the Company recognized increases in estimated costs at completion and related gross profit margins related to several projects in Jacksonville, Florida. The Company increased its prior estimates related to the costs of executing the contracts to completion, which led to a decrease in the recognized revenues to date under the percentage of completion revenue recognition methodology. As a result of these changes, net income for the year ended December 31, 2022 decreased by $7,781,220, and basic and diluted earnings per share for the year ended December 31, 2022 Cash and Cash Equivalents: Restricted Cash: Accounts Receivable: Property, Plant and Equipment: Long-Lived Assets: Goodwill and Indefinite-Lived Intangible Assets: The Company’s testing of goodwill for potential impairment involves the comparison of a reporting unit’s carrying value to its estimated fair value, which is determined using the income approach, the market approach and the cost approach. Similarly, the testing of the Company’s trade name for potential impairment involves the comparison of the carrying value of the trade name to its estimated fair value, which is determined using the relief from royalty method. If the carrying value of goodwill or the trade name is deemed to be unrecoverable, the excess of the carrying value over the estimated fair value is charged to results of operations in the period in which the impairment is determined. The Company did not have any impairment write-downs in 2022. Cost of Revenue: Warranty Costs: Insurance: Shipping and Handling Costs: — Advertising Costs: Stock-Based Compensation Expense: one Income Taxes: Under ASC 740—Income Taxes, the Financial Accounting Standards Board (“FASB”) requires companies to assess whether valuation allowances should be established against their deferred tax assets based on the consideration of all available positive and negative evidence, using a “more likely than not” standard. In making such assessments, significant weight is given to evidence that can be objectively verified. A company’s current or previous operating history is given more weight than its future outlook, although the Company does consider future taxable income projections, ongoing tax planning strategies and the limitation on the use of carryforward losses in determining valuation allowance needs. The Company establishes valuation allowances for its deferred tax assets if, based on the available evidence, it is more likely than not that some portion of or all the deferred tax assets will not be realized. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. The Company recognizes the tax benefit from uncertain tax positions only if it is more likely than not to be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The Company believes that its benefits and accruals recognized are appropriate for all open audit years based on its assessment of many factors including past experience and interpretation of tax law. This assessment relies on estimates and assumptions and may involve a series of complex judgments about future events. To the extent that the final tax outcome of these matters is determined to be different than the amounts recorded, those differences will impact income tax expense in the period in which the determination is made. Other Comprehensive Income (Loss): Adoption of New Accounting Pronouncements The Company did not implement any new accounting pronouncements during 2022. However, the Company is currently evaluating the impact of future disclosures that may arise under recent SEC proposals.

LEASES
LEASES	NOTE 4—LEASES In accordance with ASU 2016-02, the recognition of right-of-use assets and lease liabilities on the balance sheet for leases with terms greater than twelve months or leases that contain a purchase option that is reasonably certain to be exercised, require lessees to classify leases as either finance or operating leases. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. The Company primarily leases office space and related equipment, as well as equipment, modular units and vehicles directly used in providing services to our customers. The Company’s leases have remaining lease terms of one renewal For leases with terms greater than twelve months, the Company records the related right-of-use assets and lease liabilities at the present value of the fixed lease payments over the term at the commencement date. The Company uses its incremental borrowing rate to determine the present value of the lease as the rate implicit in the lease is typically not readily determinable. Short-term leases (leases with an initial term of twelve months or less or leases that are cancelable by the lessee and lessor without significant penalties) are expensed on a straight-line basis over the lease term. The majority of the Company’s short-term leases relate to equipment used in delivering services to its customers. These leases are entered into at agreed upon hourly, daily, weekly, or monthly rental rates for an unspecified duration and typically have a termination for convenience provision. Such equipment leases are considered short-term in nature unless it is reasonably certain that the equipment will be leased for a term greater than twelve months. On September 2, 2021, the Company made the decision to relocate its corporate headquarters to Atlanta, Georgia and entered into a ten-year lease agreement. The Company completed its relocation in March 2022. The lease is presented as a right-of-use asset and lease liability and the lease liability amounts to $3.3 million with a present value of $2.2 million over a ten-year term. If the Company defaults, the landlord has the right to use the security deposit for rent or other payments due to other damages, injury, expense or liability as defined in the lease agreement. Although the security deposit shall be deemed the property of the landlord, any remaining balance of the security deposit shall be returned by the landlord to the Company after termination of the lease as the Company’s obligations under the lease have been fulfilled. The Company subleased a portion of its former office space and collected $59,000 of sublease income during 2022. The components of lease expense for the years ended December 31, 2022 and 2021 were as follows: ​ ​ ​ ​ ​ ​ ​ Lease Cost/(Sublease Income) (in thousands) ​ 2022 2021 Operating lease cost ​ $ 2,202 $ 2,263 Short-term lease cost ​ ​ 7,140 ​ 3,813 Sublease income ​ ​ (59) ​ (20) Total lease cost ​ $ 9,283 $ 6,056 ​ Lease cost related to finance leases was not significant for the year ended December 31, 2022.

CHANGES IN BUSINESS	NOTE 5—CHANGES IN BUSINESS Discontinued Operations Electrical Solutions During the fourth quarter of 2017, the Company made the decision to exit and sell its Electrical Solutions segment in an effort to reduce the Company’s outstanding term debt. The Company determined that the decision to exit this segment met the definition of a discontinued operation. As a result, this segment has been presented as a discontinued operation for all periods presented. On July 11, 2018, Koontz-Wagner filed a voluntary petition for relief under Chapter 7 of Title 11 of the Bankruptcy Code with the U.S. Bankruptcy Court for the Southern District of Texas. The filing was for Koontz-Wagner only, not for the Company as a whole, and was completely separate and distinct from the Williams business and operations. As a result of the July 11, 2018 bankruptcy of Koontz-Wagner, the Company recorded a pension withdrawal liability of $2.9 million related to Koontz-Wagner’s International Brotherhood of Electrical Workers Local Union 1392 (“IBEW”) multi-employer pension plan. After an arbitration process, on May 12, 2021, an arbitrator concluded that the IBEW used an incorrect per hour contribution rate in calculating the Company’s pension withdrawal liability, which resulted in the Company overpaying. The arbitrator directed IBEW to refund all overpayments, with interest, to the Company and to redetermine the Company’s payments going forward using the proper contribution rate. Accordingly, the Company’s overall pension withdrawal liability decreased by approximately $0.3 million. The pension liability is expected to be satisfied by annual cash payments of $0.3 million each, paid in quarterly installments, through 2038. The Company recorded a gain on disposal of approximately $0.3 million in 2021 to reduce its previously recorded estimated withdrawal liability to the new amount. Mechanical Solutions During the third quarter of 2017, the Company made the decision to exit and sell substantially all of the operating assets and liabilities of its Mechanical Solutions segment and determined that the decision to exit this segment met the definition of a discontinued operation. As a result, this segment has been presented as a discontinued operation for all periods presented.

GOODWILL AND OTHER INTANGIBLE ASSETS
GOODWILL AND OTHER INTANGIBLE ASSETS	NOTE 7—GOODWILL AND OTHER INTANGIBLE ASSETS The Company determines the fair value of its reporting unit using a combination of income, market and cost approaches. For purposes of the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. The Company uses its internal forecasts to estimate future cash flows and includes an estimate of long-term future growth rates based on its most recent views of the long-term outlook for the reporting unit, which falls within Level 3 of the fair value hierarchy. Under the market approach, the fair value is determined by utilizing comparative market multiples in the valuation estimates. The cost approach is based on the assumption that a prudent investor would pay no more for a security or asset than the amount at which it could be replaced or reproduced and is performed by estimating the replacement cost. As of each of December 31, 2022 and 2021, the Company had $12.5 million of unamortizable indefinite-lived intangible assets related to its Williams Industrial Services Group trade name. The Company did not incur any amortization expense for each of the years ended December 31, 2022 and 2021, respectively. The Company determines the fair value of its trade name using the relief from royalty method. Under that method, the fair value of the trade name is determined by calculating the present value of the after-tax cost savings associated with owning the asset and therefore not having to pay royalties for its use for the remainder of its estimated useful life. As a result of the Company’s annual indefinite-lived intangible asset impairment analysis as of October 1, 2022 and 2021, the Company determined the fair value of its trade name exceeded its book value; therefore, no impairment charge was recorded for the years ended December 31, 2022 and 2021. Goodwill and indefinite-lived intangible assets are tested for impairment annually as of October 1 and whenever events or circumstances indicate that the carrying value may not be recoverable. In accordance with ASC 350—Intangibles—Goodwill and Other, the Company observed certain qualitative circumstances related to performance and current market conditions that indicated the potential for impairment in 2022. As a result the Company engaged an independent consulting firm to perform its annual goodwill impairment analysis as of October 1, 2022, and determined that the fair value of its reporting unit exceeded its book value, and accordingly, no impairment charge was necessary for the years ended December 31, 2022 and 2021. Estimating the fair value of reporting units and trade names requires the use of estimates and significant judgments that are based on a number of factors including current and historical actual operating results, balance sheet carrying values, the Company’s most recent forecasts, and other relevant quantitative and qualitative information, including an estimated rate of return and discount rate. If current or expected conditions deteriorate, it is reasonably possible that the judgments and estimates described above could change in future periods and result in impairment charges.

The net deferred tax liabilities for the years ended December 31, 2022 and 2021 predominantly related to indefinite-lived intangible deferred tax liabilities that can be used to offset deferred tax assets without valuation allowances. A net increase in valuation allowances related to continuing operations of $3.1 million as of December 31, 2022 was recorded against the gross deferred tax asset balances as of December 31, 2022. As of December 31, 2022, the Company would need to generate $306.6 million of future U.S. pre-tax income to realize its deferred tax assets. Inflation Reduction Act of 2022 On August 16, 2022, the Inflation Reduction Act of 2022 (“IRA”) was signed into law, making significant changes to the Internal Revenue Code. Such changes include, but are not limited to, a 15% corporate minimum income tax and a 1% excise tax on corporate stock repurchases in tax years beginning after December 31, 2022. While these tax law changes have no immediate effect and are not expected to have a material adverse effect on the Company’s results of operations going forward, the Company will continue to evaluate the IRA’s impact as further information becomes available. Net Operating Losses and Tax Credit Carryforwards As of December 31, 2022, the Company had $242.8 million of federal net operating loss carryforwards expiring between 2026 2037 2023 2042 2027 2023 2027 Under the Internal Revenue Code, the amount of and the benefits from net operating loss (“NOL”) and tax credit carryforwards may be limited or permanently impaired in certain circumstances. In addition, under the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), the amount of post 2017 NOLs that the Company is permitted to deduct in any taxable year is limited to 80% of its taxable income in such year, where taxable income is determined without regard to the NOL deduction itself. The Tax Act also generally eliminates the ability to carry back any NOL to prior taxable years, while allowing post 2017 unused NOLs to be carried forward indefinitely.

The Company has elected to classify interest and penalties related to uncertain income tax positions in income tax expense. As of December 31, 2022, the Company accrued $1.1 million for potential payment of interest and penalties, compared with $1.5 million accrued as of December 31, 2021. As of each of December 31, 2022 and 2021, the total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $0.1 million. In 2022, the Company released approximately $0.3 million of accruals of uncertain tax positions as the statute of limitations related to these liabilities will lapse in 2022. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was enacted and signed into U.S. law to provide economic relief to individuals and businesses facing economic hardship as a result of the COVID-19 pandemic. The Company has incorporated the impact of the CARES Act to the tax provision. In addition, the Company deferred payments of federal employer payroll taxes of approximately $4.9 million, as permitted by the CARES Act. The first half of the deferred amounts were paid in December 2021, and the second half were paid in December 2022. The Company files a consolidated U.S. federal income tax return.

The Closing Date Term Loan was fully drawn on the Closing Date, while the Delayed Draw Term Loan Facility was available upon the satisfaction of certain conditions precedent for up to 18 months following the Closing Date and expired in June 2022. The Term Loan Agreement matures on December 16, 2025. As of December 31, 2022, borrowings under the Term Loan Agreement bore interest at SOFR, plus a margin of 8.50% (if the Total Leverage Ratio (as defined in the Term Loan Agreement) is less than 2.50:1) or 9.00% per year (if the Total Leverage Ratio is greater than or equal to 2.50:1), subject to a minimum SOFR floor of 1.00%, payable in cash on a quarterly basis. In addition, upon the occurrence of an event of default, and for so long as such event of default continues, default interest equal to 2.00% per year in excess of the rate otherwise applicable will be payable. The Term Loan Borrowers’ Obligations (as defined in the Term Loan Agreement) are guaranteed by certain of the Company’s material, wholly owned subsidiaries, subject to customary exceptions (the “Term Loan Guarantors” and, together with the Term Loan Borrowers, the “Term Loan Credit Parties”). The Term Loan Credit Parties’ obligations are secured by first-priority security interests on substantially all of the Term Loan Credit Parties’ assets, as well as a second-priority security interest on the Term Loan Credit Parties’ accounts receivable and inventory, subject to the Intercreditor Agreement. Subject to certain conditions, the Term Loan Borrowers may voluntarily prepay the Term Loan on any Payment Date (as defined in the Term Loan Agreement), in whole or in part, in a minimum amount of $1.0 million of the outstanding principal amount, plus a prepayment fee. The prepayment fee was amended effective June 30, 2022, as described below. Subject to certain exceptions, within 120 days of the end of each calendar year, beginning with the year ended December 31, 2021, the Term Loan Borrowers must prepay the Obligations in an amount equal to (1) (i) if the Total Leverage Ratio is greater than 3:00:1:00, 50.0% of Excess Cash Flow (as defined in the Term Loan Agreement) or (ii) if the Total Leverage Ratio is equal to or less than 3:00:1:00 and greater than 2:00:1:00, 25.0% of Excess Cash Flow, less (2) all voluntary prepayments made on the Term Loan during such calendar year; provided that, so long as no default or event of default has occurred and is continuing or would result therefrom, no such prepayment will be required unless Excess Cash Flow for such calendar year equals or exceeds $0.5 million. The Company was not required to prepay any Obligations for the year ended December 31, 2022. The Term Loan Agreement also requires mandatory prepayment of certain amounts in the event the Term Loan Borrowers receive proceeds from certain events and activities, including, among others, certain asset sales and casualty events, the issuance of indebtedness and equity interests, and the receipt of extraordinary receipts (with certain exclusions), plus, in certain instances, the applicable prepayment fee. The Term Loan Agreement contains customary representations and warranties, as well as customary affirmative and negative covenants, in each case, with certain exceptions, limitations and qualifications. The Term Loan Agreement also requires the Term Loan Borrowers to regularly provide certain financial information to the lenders thereunder, maintain a maximum total leverage ratio and a minimum fixed charge coverage ratio, and comply with certain limitations on capital expenditures. Events of default under the Term Loan Agreement include, but are not limited to, a breach of certain covenants or any representations or warranties, failure to timely pay any amounts due and owing, the commencement of any bankruptcy or other insolvency proceeding, judgments in excess of certain acceptable amounts, the occurrence of a change in control, certain events related to ERISA matters, impairment of security interests in collateral or invalidity of guarantees or security documents, or a default or event of default under the Revolving Credit Agreement or the Intercreditor Agreement, in each case, with customary exceptions, limitations, grace periods and qualifications. If an event of default occurs, the Term Loan lenders may, among other things, declare all Obligations to be immediately due and payable, together with accrued interest and fees, and exercise remedies under the collateral documents relating to the Term Loan Agreement. On August 3, 2022 (the “Signing Date”), effective as of June 30, 2022, the Company entered into an Amendment to the Term Loan Agreement (the “Term Loan Amendment”) that, among other things, (i) amended and increased the Total Leverage Ratio (as defined in the Term Loan Agreement) applicable to the Company for certain periods, (ii) amended the calculation of Consolidated EBITDA (as defined in the Term Loan Agreement) to include (or “add back”) certain non-recurring losses and expenses relating to projects executed in Jacksonville, Florida, one-time costs and expenses incurred in connection with the Company’s transmission and distribution business unit start-up, and costs and expenses arising out of the Company’s litigation with a designated former executive and his employer (in each case, subject to certain specified dollar limits), (iii) provided for a fee of 1% of the then-outstanding principal balance due upon maturity of the term loan without duplication of fees paid in connection with the Company’s prepayment fee structure, (iv) extended the Company’s existing prepayment fee structure to require upon repayment (a) prior to the first anniversary of the Signing Date, a fee of 3% of the principal amount being repaid, (b) on or after the first anniversary of the Signing Date and prior to the second anniversary of the Signing Date, a fee of 2% of the principal amount being repaid, and (c) on or after the second anniversary of the Signing Date, a fee of 1% of the principal amount being repaid, and (v) provided for the payment of a $0.2 million amendment fee, plus applicable fees and expenses.

The Company received net proceeds of $8.1 million (after payment of attorney’s fees and third-party funding costs) and used these net proceeds to prepay a substantial amount of the Term Loan. The $8.1 million net proceeds, coupled with $0.3 million scheduled principal payments, reduced the Term Loan by a total of $8.4 million to $25.1 million as of September 30, 2022 (including both the noncurrent and current portion of the Term Loan). On December 30, 2022, the Company entered into a second amendment to the Term Loan Agreement, pursuant to which, among other things, the lenders agreed to defer payment of the principal, and part of the interest, due on January 1, 2023 to January 9, 2023.

On February 24, 2023, the Company entered into a fourth amendment to the Term Loan Agreement (the “Fourth Term Loan Amendment”). The Fourth Term Loan Amendment provided for delayed draw term loans in an aggregate principal amount of $1.5 million, which were funded at the time the Fourth Term Loan Amendment was signed, and discretionary delayed draw term loans in an aggregate principal amount of $3.5 million, which will be funded at the lenders’ discretion (together, the “Delayed Draw Term Loans”), subject to the conditions set forth in the Term Loan Agreement, as amended by the Fourth Term Loan Amendment. In addition to interest being payable on the same basis as existing borrowings under the Term Loan Agreement, on the earlier to occur of the maturity date or the termination date of the Term Loan Agreement or any acceleration of the obligations under the Term Loan Agreement, additional interest equal to 50% of the aggregate amount of the Delayed Draw Term Loans borrowed will be payable. The Fourth Term Loan Amendment also includes a minimum liquidity covenant. The Delayed Draw Term Loans are conditioned upon, amount other things, the Company using commercially reasonable best efforts to actively receive net cash proceeds from issuances of subordinated debt or equity of at least $0.5 million on terms acceptable to EICF and the lenders under the Term Loan Agreement, continuing its publicly announced review of strategic alternatives and, subject to the exercise by the Board of Directors of the Company of its fiduciary obligations, using commercially reasonable best efforts to conduct such review in accordance with a customary indicative timeline. The Fourth Term Loan Amendment also imposed certain additional reporting obligations on the Company, including the weekly delivery of a 13-week cash flow forecast. On February 21, 2023, the Company received a $1.0 million advance pursuant to the then-existing terms of the Term Loan Agreement and, on February 24, 2023, the Company received $1.5 million principal amount related to the delayed draw term loans allowed from the Fourth Term Loan Amendment. In addition to interest being payable on the same basis as existing borrowing under the Term Loan Agreement, on the earlier to occur of the maturity date or the termination date of the Term Loan Agreement or any acceleration of the obligations under the Term Loan Agreement, additional interest equal to $0.5 million will be payable in respect of this $1.0 million advance. The scheduled maturities of the Term Loan were as follows as of December 31, 2023: ​ ​ ​ ​ ​ December 31, ​ (in thousands) 2023 ​ $ - 2024 ​ ​ 1,312 2025 ​ ​ 23,970 Total ​ $ 25,282 ​ The Company’s borrowing rate under the Term Loan on December 31, 2022 was 11.0% plus SOFR. The Wynnefield Notes The Wynnefield Notes consist of (i) an Unsecured Promissory Note by and among the Company, as borrower, certain of its subsidiaries, as guarantors under a separate Guaranty Agreement, and Wynnefield Partners Small Cap Value, LP I in the aggregate principal amount of $400,000 and (ii) an Unsecured Promissory Note by and among the Company, as borrower, certain of its subsidiaries, as guarantors under a separate Guaranty Agreement, and Wynnefield Partners Small Cap Value, LP (together with Wynnefield Partners Small Cap Value, LP I, the “Wynnefield Lenders”) in the aggregate principal amount of $350,000. All principal and interest will be due on the maturity date of the Wynnefield Notes, which will be the earliest of (i) December 23, 2025; (ii) a change in control of the Company; (iii) a refinancing or maturity extension of either of the Term Loan Agreement or the Revolving Credit Agreement; or (iv) an acceleration following the occurrence of an event of default (as defined in the Wynnefield Notes, and which includes any default under the Term Loan Agreement or the Revolving Credit Agreement). The Wynnefield Notes bear interest at the fixed rate of (i) 8.0% per annum from the closing date; (ii) 13.0% per annum from and after the maturity date; and (iii) 13.0% per annum from and after an event of default (as defined in the Wynnefield Notes, and which includes any default under the Term Loan Agreement or the Revolving Credit Agreement).

EARNINGS PER SHARE
EARNINGS PER SHARE	NOTE 12—EARNINGS PER SHARE Basic earnings (loss) per common share are calculated by dividing net income (loss) by the weighted average common shares outstanding during the period. Diluted earnings (loss) per common share are based on the weighted average common shares outstanding during the period, adjusted for the potential dilutive effect of common shares that would be issued upon the vesting and release of restricted stock awards and units. Basic and diluted income (loss) per common share from continuing operations were calculated as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, (in thousands, except share data) 2022 2021 Income (loss) from continuing operations ​ $ (14,173) ​ $ 2,702 ​ ​ ​ ​ ​ ​ ​ Basic income (loss) per common share: ​ ​ ​ ​ ​ ​ Weighted average common shares outstanding ​ ​ 26,032,960 ​ ​ 25,506,748 ​ ​ ​ ​ ​ ​ ​ Basic income (loss) per common share ​ $ (0.54) ​ $ 0.11 ​ ​ ​ ​ ​ ​ ​ Diluted income (loss) per common share: ​ ​ ​ ​ ​ ​ Weighted average common shares outstanding ​ ​ 26,032,960 ​ 25,506,748 ​ ​ ​ ​ ​ ​ ​ Diluted effect: ​ ​ ​ ​ ​ Unvested portion of restricted stock units and awards ​ ​ — ​ ​ 630,896 Weighted average diluted common shares outstanding ​ 26,032,960 ​ 26,137,644 ​ ​ ​ ​ ​ ​ Diluted income (loss) per common share ​ $ (0.54) ​ $ 0.10 ​ As of December 31, 2022, the Company’s 26,543,391 shares outstanding included 321,142 shares of contingently issued but unvested restricted stock. As of December 31, 2021, the Company’s 25,939,621 shares outstanding included 215,956 shares of contingently issued but unvested restricted stock. Restricted stock is excluded from the calculation of basic weighted average shares outstanding, but its impact, if dilutive, is included in the calculation of diluted weighted average shares outstanding. The weighted-average number of shares outstanding used in the computation of basic and diluted earnings per share does not include the effect of the following potential outstanding common stock. The effects of the potentially outstanding service-based restricted stock and restricted stock unit awards were not included in the calculation of diluted earnings per common share because the effect would have been anti-dilutive. The effects of the potentially outstanding performance- and market-based restricted stock unit awards were not included in the calculation of diluted earnings per common share because the performance and/or market conditions had not been satisfied as of December 31, 2022 and 2021. ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ 2022 2021 Unvested service-based restricted stock and restricted stock unit awards 535,051 ​ — Unvested performance- and market-based restricted stock unit awards 643,784 ​ 765,857 ​

STOCK-BASED COMPENSATION.
STOCK-BASED COMPENSATION	NOTE 13—STOCK-BASED COMPENSATION Description of the Plans The Company has one equity incentive plan: the 2015 Equity Incentive Plan, as amended and restated on March 15, 2022 (the “2015 Plan”). The 2015 Plan allows for the issuance of up to 4,500,000 shares of stock to the Company’s employees and directors in the form of a variety of instruments, including stock options, restricted stock, restricted share units, stock appreciation rights and other share-based awards. The Company provides the option to repurchase the number of shares required to satisfy tax withholding obligations in connection with the vesting of restricted stock unit awards issued to employees participating in the 2015 Plan. The 2015 Plan also allows for cash-based awards. Generally, all participants who voluntarily terminate their employment with the Company forfeit 100% of all unvested equity awards. Persons who are terminated without cause, or in some cases leave for good reason, are generally entitled to proportionate vesting. The vesting of proportionate time-based shares is accelerated, and such shares distributed upon such individuals’ termination date. Proportionate market-based and performance-based restricted shares remain categorized as unvested pending final conclusion on the achievement of the related awards. As of December 31, 2022, the Company had approximately 1,841,944 shares available under the 2015 Plan to settle previously granted awards. During 2022, the Company granted 1,391,679 restricted shares and restricted stock units under the 2015 Plan. Total stock-based compensation expense during the years ended December 31, 2022 and 2021 was $1.7 million and $3.0 million, respectively, with no related excess tax benefit recognized, and was included in general and administrative expenses on the Company’s consolidated statements of operations. As of December 31, 2022, total unrecognized compensation expense related to all unvested restricted stock and restricted stock unit awards for which terms and conditions are known totaled $2.1 million, which is expected to be recognized over a weighted average period of 1.9 years. The fair value of shares that vested during 2022 and 2021 based on the stock price at the applicable vesting date was $1.5 million and $2.3 million, respectively. The weighted average grant date fair value of the Company’s restricted shares and restricted stock units was $1.95 and $3.27 for the years ended December 31, 2022 and 2021, respectively.

EMPLOYEE BENEFIT PLANS.
EMPLOYEE BENEFIT PLANS	NOTE 14—EMPLOYEE BENEFIT PLANS Defined Contribution Plan: Multiemployer Pension Plans: 1. Assets contributed to the multiemployer pension plan by one employer may be used to provide benefits to employees of other participating employers. 2. If a participating employer stops contributing to the multiemployer pension plan, the unfunded obligations of the multiemployer pension plan may be borne by the remaining participating employers. 3. If the Company chooses to stop participating in some of its multiemployer pension plans, it may be required to pay those plans an amount based on the underfunded status of the multiemployer pension plan, referred to as a withdrawal liability. The Company’s participation in these multiemployer pension plans during the year ended December 31, 2022 is outlined in the following table. All information in the table is as of December 31, 2022, unless otherwise stated. The “EIN/Pension Plan Number” column provides the Employer Identification Number (“EIN”) and the three-digit plan number, if applicable. Unless otherwise noted, the most recent Pension Protection Act zone status available during 2022 and 2021 is for the respective plan’s fiscal year-end as of 2022 and 2021, respectively. The zone status is based on information that the Company received from the plan and is certified by the plan’s actuary. Among other factors, plans in the green zone are at least 80 percent funded. If a plan is critical and declining, the plan sponsor may file an application with the Secretary of the Treasury requesting a temporary or permanent reduction of benefits to keep the plan from running out of money. If a fund is in critical status, adjustable benefits may be reduced and no lump sum distributions in excess of $5,000 can be made. Plans that are in critical and endangered status are required to adopt a plan aimed at restoring the financial health of the benefit plan. The “Rehab Plan Status Pending/Implemented” column indicates plans for which a financial improvement plan or a rehabilitation plan is either pending or has been implemented. The next to last column lists the expiration date of the collective-bargaining agreement to which the plans are subject. Certain plans have been aggregated in the “All Others” line in the following table, as the contributions to each of these individual plans are not material. Only with respect to multiemployer pension plans, we considered contributions in excess of $0.1 million in any period disclosed to be individually significant. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Expiration ​ ​ ​ ​ ​ Pension ​ Rehab Plan ​ ($ in thousands) ​ ​ ​ Date of ​ ​ ​ ​ ​ ​ Protection Act ​ status ​ Contributions by ​ ​ ​ Collective ​ ​ ​ ​ EIN/Pension ​ Zone Status ​ Pending/ ​ the Company ​ Surcharge ​ Bargaining ​ ​ Pension Fund ​ Plan Number ​ 2022 ​ 2021 ​ Implemented ​ 2022 ​ 2021 ​ Imposed ​ Agreement ​ Notes Boilermaker-Blacksmith National Pension Trust ​ 48-6168020 001 ​ Green ​ Endangered ​ Funding Improve ​ 2,194 ​ 4,263 ​ No (8) ​ Annual Agreements - Automatic Renewal ​ 3,4,6,9 IBEW Local 1579 Pension Plan ​ 58-1254974 001 ​ Green ​ Green ​ ​ ​ 1,337 ​ 1,239 ​ No (8) ​ Agreement through end of Job ​ 2, 3, 6, 9, 10 National Asbestos Workers Pension Plan ​ 52-6038497 001 ​ Critical ​ Critical ​ Rehab Plan 2019 ​ 1,091 ​ 1,258 ​ No (7) ​ Annual Agreements-Automatic Renewal ​ 2, 3, 9, 10 Excavators Union Local 731 Pension Fund ​ 13-1809825 002 ​ Green ​ Green ​ ​ ​ 786 ​ 523 ​ No (8) ​ Annual Agreements-Automatic Renewal ​ 6 National Electrical Benefits Fund ​ 53-0181657 001 ​ Green ​ Green ​ ​ ​ 456 ​ 578 ​ No (8) ​ Multiple Agreements ​ 10 Central Pension Fund of the IUOE and Participating Employers ​ 36-6052390 001 ​ Green ​ Green ​ ​ ​ 380 ​ 366 ​ No (8) ​ Multiple Agreements ​ 3, 11 Tri-State Carpenters & Joiners Pension Trust Fund ​ 62-0976048 001 ​ Endangered ​ Endangered ​ Funding Improve ​ 376 ​ 512 ​ No (8) ​ Annual Agreements-Automatic Renewal ​ 2, 3, 5, 10 Laborers National Pension Fund ​ 75-1280827 001 ​ Critical ​ Critical ​ Rehab Plan ​ 372 ​ 417 ​ No (7) ​ Multiple Agreements ​ 1, 2, 3, 5, 9, 10 New Jersey Building Laborers Statewide Pension Fund ​ 22-6077693 001 ​ Critical ​ Critical ​ Rehab Plan ​ 356 ​ 1,340 ​ No (7) ​ Annual Agreements-Automatic Renewal ​ 3 Southern Ironworkers Pension Plan ​ 59-6227091 001 ​ Green ​ Green ​ ​ ​ 355 ​ 270 ​ No (8) ​ Agreement through end of Job ​ 2, 3, 4, 5, 9, 10 United Association National Pension Fund ​ 52-6152779 001 ​ Green ​ Endangered ​ Funding Improve ​ 341 ​ 315 ​ No (7) ​ Multiple Agreements ​ 9 Connecticut laborers Pension Plan ​ 06-6044348 001 ​ Green ​ Green ​ ​ ​ 228 ​ 37 ​ No (8) ​ CBA (Expires 03/31/23) ​ 2, 3, 4, 5, 9, 10 Iron Workers District Council of Tennessee Valley & Vicinity Pension Plan ​ 62-6098036 001 ​ Green ​ Green ​ ​ ​ 225 ​ 316 ​ No (8) ​ Annual Agreements-Automatic Renewal ​ 9, 11 IUPAT Industry Pension Plan ​ 52-6073909 001 ​ Critical ​ Seriously Endangered ​ Rehab Plan ​ 184 ​ 184 ​ No (8) ​ Multiple Agreements ​ 3, 11 Iron Workers Local No. 402 Pension Trust ​ 59-6227518 001 ​ Critical ​ Critical ​ Rehab Plan ​ 124 ​ 47 ​ No (8) ​ Annual Agreements-Automatic Renewal ​ 10, 11 IUOE Local 478 Pension Fund ​ 06-0733831 001 ​ Green ​ Green ​ ​ ​ 108 ​ 29 ​ No (8) ​ CBA (Expires 03/31/23) ​ 3 Pavers and Road Builders District Council Pension Fund ​ 13-1990171 074 ​ Green ​ Green ​ ​ ​ 104 ​ 62 ​ No (8) ​ Annual Agreements-Automatic Renewal ​ 4, 11 Central States, Southeast, and Southwest Pension Fund ​ 36-6044243 001 ​ Critical & Declining ​ Critical & Declining ​ Rehab Plan ​ 104 ​ 103 ​ No (8) ​ Multiple Agreements ​ 4, 11 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ All Others ​ ​ ​ ​ ​ ​ ​ ​ ​ 1,437 ​ 3,983 ​ ​ ​ ​ ​ ​ Total ​ ​ ​ ​ ​ ​ ​ ​ ​ 10,558 ​ 15,842 ​ ​ ​ ​ ​ ​ ​ (1) Defined Benefit Plans for Unions employed through the GPPMA agreement for St. Lucie and Turkey Point.

The Nuclear Power Construction Agreement is for new work at Vogtle and runs through the duration of the project. (11) The status of this plan had not been issued as of the date of filing this Form 10-K. A plan in green status with a calendar year has the option to issue its Annual Funding Notice in March or April of the subsequent year . Employees covered by multiemployer pension plans are hired for project-based building and construction purposes. The Company’s participation level in these plans varies as a result. The Company believes that its responsibility for potential withdrawal liabilities associated with participating in multiemployer plans is limited because the building and construction trades exemption should apply to the substantial majority of the Company’s plan contributions. However, pursuant to the Pension Protection Act of 2006 and other applicable laws, the Company is also exposed to other potential liabilities associated with plans that are underfunded. As of December 31, 2022, the Company had been notified that certain pension plans were in critical funding status. Currently, certain plans are developing, or have developed, a rehabilitation plan that may call for a reduction in participant benefits or an increase in future employer contributions. Therefore, in the future, the Company could be responsible for potential surcharges, excise taxes and/or additional contributions related to these plans. Additionally, market conditions and the number of participating employers remaining in each plan may result in a reorganization, insolvency or mass withdrawal that could materially affect the funded status of multiemployer plans and the Company’s potential withdrawal liability, if applicable. The Company continues to actively monitor, assess, and take steps to limit its potential exposure to any surcharges, excise taxes, additional contributions and/or withdrawal liabilities. However, the Company cannot, at this time, estimate the full amount, or even the range, of this potential exposure.

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	NOTE 15—COMMITMENTS AND CONTINGENCIES Litigation and Claims: The Company completed a bankruptcy filing of its Koontz-Wagner subsidiary on July 11, 2018. This could require the Company to incur legal fees and other expenses related to liabilities from this bankruptcy filing. While the Company does not anticipate these liabilities will have a material adverse effect on its results of operations, cash flows and financial position, and although the statute of limitations has run on certain claims that the Chapter 7 Trustee for the Koontz-Wagner estate might assert, there can be no assurance of the outcome. The filing was for Koontz-Wagner only, not for the Company as a whole, and was completely separate and distinct from the Williams business and operations. For additional information, please refer to “Note 5—Changes in Business” to the consolidated financial statements. The acquiror of certain assets from a former operating unit of the Company has been named as a defendant in an asbestos personal injury lawsuit and has submitted a claim for indemnification and tendered defense of the matter to the Company. The Company has assumed defense of the matter subject to a reservation of rights and objection to the claim for indemnification. Neither the Company nor its predecessors ever mined, manufactured, produced or distributed asbestos fiber, the material that allegedly caused the injury underlying this action. The Company does not expect that this claim will have a material adverse effect on its financial position, results of operations or liquidity. Moreover, during 2012, the Company secured insurance coverage that will help to reimburse the defense costs and potential indemnity obligations of its former operating unit relating to these claims. The Company intends to vigorously defend all currently active actions, and it does not anticipate that this action will have a material adverse effect on its financial position, results of operations or liquidity. However, the outcomes of any legal action cannot be predicted and, therefore, there can be no assurance that this will be the case. Insurance: The Company’s consolidated balance sheets include amounts representing its probable estimated liability related to insurance-related claims that are known and have been asserted against the Company, and for insurance-related claims that are believed to have been incurred but had not yet been reported as of December 31, 2022 and 2021. As of both December 31, 2022 and 2021, the Company provided $0.9 million in letters of credit and provided cash collateral of $1.5 million as security for possible workers’ compensation claims.

SUBSEQUENT EVENTS	NOTE 18—SUBSEQUENT EVENTS In the first quarter of 2023, the Company entered into the following engagement and amendments, each of which is described below: ● the third and fourth amendment to the Revolving Credit Facility; ● the third and fourth amendment to the Term Loan; ● the Wynnefield Notes, which are two unsecured promissory notes in favor of the Wynnefield Lenders. On January 9, 2023, the Company entered into the Third Revolving Credit Amendment to the Revolving Credit Agreement. The Third Revolving Credit Amendment, among other things, (i) modified the financial covenants to require that the Company achieve certain designated minimum levels of trailing twelve-month EBITDA (as defined in the Revolving Credit Agreement) as of the end of each fiscal month beginning on February 5, 2023, and ending December 31, 2023; (ii) amended the calculation of EBITDA to include (or “add back”) certain non-recurring losses and expenses incurred in connection with projects executed by the Company’s Jacksonville, Florida office, one-time costs and expenses incurred in connection with the Company’s transmission and distribution business segment start-up, non-recurring costs and expenses arising out of the implementation of a ERP system, and non-recurring costs and expenses arising out of pro forma headcount reductions implemented by the Company and certain litigation with a former executive and a competitor of the Company that was settled in the fourth quarter of 2022 (in each case, subject to certain specific dollar limits for certain fiscal quarters commencing in the second fiscal quarter of 2021 and ending December 31, 2022); (iii) provided temporary reserve relief of up to $1.0 million from the date of the Third Revolving Credit Amendment until June 30, 2023; (iv) reduced the Eligible Unbilled Receivables (as defined in the Revolving Credit Agreement) sublimit from $7.5 million to $5.5 million; (v) increased the Applicable Margin (as defined in the Revolving Credit Agreement) by 2%; and (vi) provided for an amendment fee of $0.3 million payable when the loan obligations under the Revolving Credit Agreement are repaid or, if earlier, June 30, 2023, and an exit fee of $0.3 million to be paid upon the occurrence of certain stated events, including a prepayment or maturity of the loan obligations under the Revolving Credit Agreement. Additionally, on February 21, 2023, the Company entered into the Fourth Revolving Credit Amendment. The Fourth Revolving Credit Amendment, among other things, provided for the consent of PNC to the Fourth Term Loan Amendment and incorporated into the Revolving Credit Agreement, certain of the conditions and covenants provided for in the Fourth Term Loan Amendment, including the conditions to the Delayed Draw Term Loans, the minimum liquidity covenant and the additional reporting obligations. On January 9, 2023, the Company entered into a Third Term Loan Amendment that, among other things, (i) modified the financial covenants to require that the Company achieve certain designated minimum levels of trailing twelve-month EBITDA (as defined in the Term Loan Agreement) as of the end of each fiscal month beginning on February 5, 2023, and ending December 31, 2023; (ii) amended the calculation of EBITDA to include (or “add back”) certain non-recurring losses and expenses incurred in connection with certain projects executed by the Company’s Jacksonville, Florida office, one-time costs and expenses incurred in connection with the Company’s transmission and distribution business segment start-up, non-recurring costs and expenses arising out of the implementation by the Company of a ERP system, and non-recurring costs and expenses arising out of pro forma headcount reductions implemented by the Company and certain litigation with a former executive and a competitor of the Company that was settled in the fourth quarter of 2022 (in each case, subject to certain specific dollar limits for certain fiscal quarters commencing in the second fiscal quarter of 2021 and ending December 31, 2022); (iii) adjusted the applicable interest rate to SOFR (as defined in the Term Loan Agreement) plus 11%; (iv) for each quarterly interest payment commencing January 1, 2023 through and including January 1, 2024, capped the amount of quarterly interest payable in cash at 10% per annum, with the remainder being payable in kind; (v) deferred amortization payments from the January 1, 2023 quarterly payment date until and including the January 1, 2024 quarterly payment date; (vi) increased the excess cash flow sweep from 50% to 75% for the fiscal year ending December 31, 2023 and each fiscal year thereafter; (vii) required certain additional reporting obligations, including the delivery of weekly updates of a 13-week cash flow forecast and hosting additional periodic conference calls with management and named advisors; (viii) increased, from the pre-existing levels, the permitted total leverage of the Company for the four quarter periods ended December 31, 2022 through March 31, 2024; and (ix) provided for an amendment fee equal to 1% of the principal loan balance under the Term Loan Agreement, payable in kind. On February 24, 2023, the Company entered into the Fourth Term Loan Amendment. The Fourth Term Loan Amendment provided for delayed draw term loans in an aggregate principal amount of $1.5 million, which were funded at the time the Fourth Term Loan Amendment was signed, and discretionary delayed draw term loans in an aggregate principal amount of $3.5 million, which will be funded at the lenders’ discretion (together, the “Delayed Draw Term Loans”), subject to the conditions set forth in the Term Loan Agreement, as amended by the Fourth Term Loan Amendment. In addition to interest being payable on the same basis as existing borrowings under the Term Loan Agreement, on the earlier to occur of the maturity date or the termination date of the Term Loan Agreement or any acceleration of the obligations under the Term Loan Agreement, additional interest equal to 50% of the aggregate amount of the Delayed Draw Term Loans borrowed will be payable. The Fourth Term Loan Amendment also includes a minimum liquidity covenant. The Delayed Draw Term Loans are conditioned upon, amount other things, the Company using commercially reasonable best efforts to actively receive net cash proceeds from issuances of subordinated debt or equity of at least $0.5 million on terms acceptable to EICF and the lenders under the Term Loan Agreement, continuing its publicly announced review of strategic alternatives and, subject to the exercise by the Board of Directors of the Company of its fiduciary obligations, using commercially reasonable best efforts to conduct such review in accordance with a customary indicative timeline. The Fourth Term Loan Amendment also imposed certain additional reporting obligations on the Company, including the weekly delivery of a 13-week cash flow forecast. On February 21, 2023, the Company received a $1.0 million advance pursuant to the then-existing terms of the Term Loan Agreement and, on February 24, 2023, the Company received $1.5 million principal amount related to the delayed draw term loans allowed from the Fourth Term Loan Amendment. In addition to interest being payable on the same basis as existing borrowing under the Term Loan Agreement, on the earlier to occur of the maturity date or the termination date of the Term Loan Agreement or any acceleration of the obligations under the Term Loan Agreement, additional interest equal to $0.5 million will be payable in respect of this $1.0 million advance. The Wynnefield Notes consist of (i) an Unsecured Promissory Note by and among the Company, as borrower, certain of its subsidiaries, as guarantors under a separate Guaranty Agreement, and Wynnefield Partners Small Cap Value, LP I in the aggregate principal amount of $400,000 and (ii) an Unsecured Promissory Note by and among the Company, as borrower, certain of its subsidiaries, as guarantors under a separate Guaranty Agreement, and Wynnefield Partners Small Cap Value, LP in the aggregate principal amount of $350,000. All principal and interest will be due on the maturity date of the Wynnefield Notes, which will be the earliest of (i) December 23, 2025; (ii) a change in control of the Company; (iii) a refinancing or maturity extension of either of the Term Loan Agreement or the Revolving Credit Agreement; or (iv) an acceleration following the occurrence of an event of default (as defined in the Wynnefield Notes, and which includes any default under the Term Loan Agreement or the Revolving Credit Agreement). The Wynnefield Notes bear interest at the fixed rate of (i) 8.0% per annum from the closing date; (ii) 13.0% per annum from and after the maturity date; and (iii) 13.0% per annum from and after an event of default (as defined in the Wynnefield Notes, and which includes any default under the Term Loan Agreement or the Revolving Credit Agreement). The Wynnefield Notes are subject to an aggregate exit fee of $100,000, payable upon the earlier of an event of default or payment in full of all obligations due under the Wynnefield Notes. In connection with the Wynnefield Notes, the Company, certain of its subsidiaries, the Wynnefield Lenders and the agents under each of the Revolving Credit Agreement and the Term Loan Agreement have entered into two Subordination and Intercreditor Agreements, pursuant to which the Wynnefield Lenders have agreed, on the terms and subject to the conditions set forth therein, to subordinate the Wynnefield Notes to the obligations of the Company under the Revolving Credit Agreement and the Term Loan Agreement. The Wynnefield Lenders, together with their affiliates, are the Company’s largest equity investor. Nelson Obus, a member of the Company’s Board of Directors, is a managing member of Wynnefield Capital Management, LLC, the general partner of the Wynnefield Lenders. As future advances of Delayed Draw Term Loans are discretionary on the part of our Term Loan lenders, it is possible that the Term Loan lenders may require enhanced rights or additional fees or interest before funding future advances. In certain circumstances, we may require the consent of PNC before we can agree to such terms. Such a consent from PNC, and any proposed amendments to our intercreditor agreement that might be associated with such a consent, may involve the payment of further fees and expenses by the Company to PNC and any amendments to our intercreditor agreement may require negotiations between our Term Loan lenders, PNC and the Company. A failure to procure any necessary consents or a failure to successfully negotiate such amendments to our intercreditor agreement could result in future Delayed Draw Term Loans not being available to the Company, which could have a material adverse effect on our liquidity position and our operations. The Company anticipates that enhanced rights or additional fees or interest in relation to the funding of future advances of Delayed Draw Term Loans will be forthcoming and that consent fees and related amendments to the Company’s intercreditor agreement may be requested or required by our lenders and may be agreed to by the Company in order to secure necessary funding.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2022
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Principles of Consolidation and Joint Ventures	Principles of Consolidation and Joint Ventures: In 2017, the Company formed a limited liability company (“LLC”) with an unrelated third party for the execution of a nuclear plant construction project. The Company has a 25 percent participation interest in this LLC, with distribution of expected gains and losses being proportionate to its participation interest. Although the LLC holds the construction contract with the client, the services required by the contract are performed by either the LLC, the Company, or the other member of the LLC, or by other subcontractors under subcontracting agreements with the LLC. The Company accounts for its investment in this LLC using the equity method. The Company’s investment in this LLC was $1.9 million and $2.5 million as of December 31, 2022 and 2021, respectively, and was included in other long-term assets on the consolidated balance sheets. Accounts receivable related to work performed for the Company’s unconsolidated investment in the LLC, included in accounts receivable, net, on the consolidated balance sheets, was $4.8 million and $4.6 million as of December 31, 2022 and 2021, respectively. The Company’s pro-rata share of net income from the LLC was $0.2 million and $0.7 million for the years ended December 31, 2022 and 2021, respectively, and was included in other (income) expense, net, on the consolidated statements of operations. In addition, the Company received a dividend in 2022 of $0.8 million for the period ended December 31, 2021 but did not receive a dividend for the period ended on December 31, 2022.
Discontinued Operations	Discontinued Operations: On July 11, 2018, Koontz-Wagner filed a voluntary petition for relief under Chapter 7 of Title 11 of the Bankruptcy Code with the U.S. Bankruptcy Court for the Southern District of Texas. The filing was for Koontz-Wagner only, not for the Company as a whole, and was completely separate and distinct from the Williams business and operations. Unless otherwise specified, the financial information presented in the accompanying financial statements and following notes relates to the Company’s continuing operations; it excludes any results of its discontinued operations. For additional information, please refer to “Note 5—Changes in Business” for financial information on the Company’s discontinued operations.
Segment and Geographic Information	Segment and Geographic Information The Company uses operating income (loss) to compare and evaluate its financial performance. For the year ended December 31, 2022, the Company earned 97.7% and 2.3% of its revenue in the U.S. and Canada, respectively. For the year ended December 31, 2021, the Company earned 88.1% and 11.9% of its revenue in the U.S. and Canada, respectively.
Use of Estimates	Use of Estimates:
Revenue Recognition	Revenue Recognition: The Company’s contracts generally include a single performance obligation for which revenue is recognized over time, as performance obligations are satisfied, due to the continuous transfer of control to the customer. For cost-plus contracts, the Company recognizes revenue when services are performed and contractually billable based upon the hours incurred and agreed-upon hourly rates. Revenue on fixed-price contracts is recognized and invoiced over time using the cost-to-cost percentage-of-completion method. To the extent a contract is deemed to have multiple performance obligations, the Company allocates the transaction price of the contract to each performance obligation using its best estimate of the standalone selling price of each distinct good or service in the contract. The Company does not adjust the price of the contract for the effects of a significant financing component. Change orders are generally not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as a modification of the existing contract and performance obligation. The Company believes these methods of revenue recognition most accurately reflect the economics of the transactions with its customers. The Company’s contracts may include several types of variable consideration, including change orders, rate true-up provisions, retainage, claims, incentives, penalties, and liquidated damages. The Company estimates the amount of revenue to be recognized on variable consideration using estimation methods that best predict the amount of consideration to which the Company expects to be entitled. The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based on an assessment of its anticipated performance and all information (historical, current, and forecasted) that is reasonably available. The Company updates its estimate of the transaction price each reporting period and the effect of variable consideration on the transaction price is recognized as an adjustment to revenue on a cumulative catch-up basis. In circumstances where the Company cannot reasonably determine the outcome of a contract, it recognizes revenue over time as the work is performed, but only to the extent of recoverable costs incurred (i.e., zero margin). A loss provision is recorded for the amount of any estimated unrecoverable costs in excess of total estimated revenue on a contract as soon as the Company becomes aware. The Company generally provides a limited warranty for a term of two years or less following completion of services performed under its contracts. Historically, warranty claims have not resulted in material costs incurred. During the year ended December 31, 2022, the Company recognized increases in estimated costs at completion and related gross profit margins related to several projects in Jacksonville, Florida. The Company increased its prior estimates related to the costs of executing the contracts to completion, which led to a decrease in the recognized revenues to date under the percentage of completion revenue recognition methodology. As a result of these changes, net income for the year ended December 31, 2022 decreased by $7,781,220, and basic and diluted earnings per share for the year ended December 31, 2022

Goodwill and Indefinite-Lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets: The Company’s testing of goodwill for potential impairment involves the comparison of a reporting unit’s carrying value to its estimated fair value, which is determined using the income approach, the market approach and the cost approach. Similarly, the testing of the Company’s trade name for potential impairment involves the comparison of the carrying value of the trade name to its estimated fair value, which is determined using the relief from royalty method. If the carrying value of goodwill or the trade name is deemed to be unrecoverable, the excess of the carrying value over the estimated fair value is charged to results of operations in the period in which the impairment is determined. The Company did not have any impairment write-downs in 2022.

Income Taxes	Income Taxes: Under ASC 740—Income Taxes, the Financial Accounting Standards Board (“FASB”) requires companies to assess whether valuation allowances should be established against their deferred tax assets based on the consideration of all available positive and negative evidence, using a “more likely than not” standard. In making such assessments, significant weight is given to evidence that can be objectively verified. A company’s current or previous operating history is given more weight than its future outlook, although the Company does consider future taxable income projections, ongoing tax planning strategies and the limitation on the use of carryforward losses in determining valuation allowance needs. The Company establishes valuation allowances for its deferred tax assets if, based on the available evidence, it is more likely than not that some portion of or all the deferred tax assets will not be realized. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. The Company recognizes the tax benefit from uncertain tax positions only if it is more likely than not to be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The Company believes that its benefits and accruals recognized are appropriate for all open audit years based on its assessment of many factors including past experience and interpretation of tax law. This assessment relies on estimates and assumptions and may involve a series of complex judgments about future events. To the extent that the final tax outcome of these matters is determined to be different than the amounts recorded, those differences will impact income tax expense in the period in which the determination is made.
