We are a global leading provider of integrated, digitally-enabled asset performance assurance and optimization solutions. We deploy conventional to highly specialized inspection, condition assessment, maintenance and repair services that result in greater safety, reliability, and operational efficiency for our clients’ most critical assets. Prior to the sale of our Quest Integrity segment as discussed below, we conducted operations in three segments: Inspection and Heat Treating, Mechanical Services and Quest Integrity. We currently conduct operations in two segments. Through the capabilities and resources in these two segments, we believe that we are uniquely qualified to provide integrated solutions involving: inspection to assess condition; engineering assessment to determine fitness for purpose in the context of industry standards and regulatory codes; and mechanical services to repair, rerate or replace based upon the client’s election. In addition, we are capable of escalating with the client’s needs, as dictated by the severity of the damage found and the related operating conditions, from standard services to some of the most advanced services and integrated asset integrity and reliability management solutions available in the industry. We also believe that we are unique in our ability to provide services in three distinct client demand profiles: (i) turnaround or project services, (ii) call-out services, and (iii) nested or run-and-maintain services.

On November 1, 2022, we completed the sale of all of the issued and outstanding equity interests of our wholly-owned subsidiary, TQ Acquisition Inc., a Texas corporation, to Baker Hughes Holdings LLC for an aggregate purchase price of approximately $279.0 million, after certain post-closing adjustments pursuant to that certain Equity Purchase Agreement by and among us and Baker Hughes, dated as of August 14, 2022. TQ Acquisition and its subsidiaries constituted Quest Integrity, which provided integrity and reliability management solutions for the process, pipeline and power sectors. In connection with the Quest Integrity Transaction, the credit support in the form of guarantees by and liens on assets, as applicable, of TQ Acquisition and its subsidiaries in respect of our existing debt arrangements were released. We used approximately $238.0 million of the net proceeds from the Quest Integrity Transaction to pay down $225.0 million of our term loan debt, and certain fees associated with that repayment and related accrued interest, with the remainder reserved for general corporate purposes, thereby reducing our future debt service obligations and leverage, and improving our liquidity.

The criteria for reporting Quest Integrity as a discontinued operation were met as of completion of the Quest Integrity sale transaction and, as such, all periods presented in this Form 10-K have been recast to present Quest Integrity as a discontinued operation. Unless otherwise specified, the financial information and discussion in this Form 10-K are based on our continuing operations (IHT and MS segments) and exclude any results of our discontinued operations (Quest Integrity). Refer to Note 2 - Discontinued Operations for additional details.

IHT provides conventional and advanced non-destructive testing (“NDT”) services primarily for the process, pipeline and power sectors, pipeline integrity management services, and field heat treating services, as well as associated engineering and condition assessment services. These services can be offered while facilities are running (on-stream), during facility turnarounds or during new construction or expansion activities. IHT also provides advanced digital imaging including remote digital video imaging.

MS provides solutions designed to serve clients’ unique needs during both the operational (onstream) and off-line states of their assets. Our onstream services include our range of standard to custom-engineered leak repair and composite solutions; emissions control and compliance; hot tapping and line stopping; and on-line valve insertion solutions, which are delivered while assets are in an operational condition, which maximizes client production time. Asset shutdowns can be planned, such as a turnaround maintenance event, or unplanned, such as those due to component failure or equipment breakdowns. Our specialty maintenance, turnaround and outage services are designed to minimize client downtime and are primarily delivered while assets are off-line and often through the use of cross-certified technicians, whose multi-craft capabilities deliver the production needed to achieve tight time schedules. These critical services include on-site field machining; bolted-joint integrity; vapor barrier plug testing; and valve management solutions.

Prior to its sale, Quest Integrity provided integrity and reliability management solutions for the process, pipeline and power sectors. These solutions encompass two broadly-defined disciplines: (1) highly specialized in-line inspection services for historically unpiggable process piping and pipelines using proprietary in-line inspection tools and analytical software; and (2) advanced engineering and condition assessment services through a multi-disciplined engineering team and related lab support. As referenced previously, Quest Integrity is now reported as discontinued operations.

CARES Act. Under the Coronavirus Aid, Relief and Economic Security Act we qualified to defer the employer portion of social security taxes incurred through the end of calendar year 2020. We deferred total employer payroll taxes of $14.1 million. We paid $7.0 million of the deferred payroll taxes in January 2022 and transferred $0.5 million of such obligation as part of the Quest Integrity sale transaction to the buyer. The remaining amount of $6.6 million, outstanding as of December 31, 2022, was paid in January 2023. Additionally, other governments in jurisdictions where we operate passed legislation to provide employers with relief programs, which include wage subsidy grants, deferral of certain payroll related expenses and tax payments and other benefits. We elected to treat qualified government subsidies from Canada and other governments as offsets to the related expenses. As these other governments review compliance with their relief programs, we may be required to return a portion of these funds. We recognized $0.6 million and $0.1 million as a reduction to operating expenses and selling, general and administrative expenses, respectively, during the twelve months ended December 31, 2022. We recognized $6.2 million and $1.5 million as a reduction to operating expenses and selling, general and administrative expenses, respectively, during the twelve months ended December 31, 2021. We also deferred certain payroll related expenses and tax payments under other foreign government programs. We had $2.1 million and $3.2 million as of December 31, 2022 and 2021, respectively, related to these foreign deferrals.

Reverse Stock Split. On November 2, 2022, the Company’s shareholders approved a proposal to authorize the Board to implement a reverse stock split of the outstanding shares of the Company’s common stock at a ratio of one-for-ten. The Board approved the Reverse Stock Split on December 9, 2022, which became effective on December 21, 2022. As of the effective date, every ten issued and outstanding shares of common stock was converted into one share of common stock, The common stock began trading on a reverse split-adjusted basis on the NYSE at the opening of trading on December 22, 2022.

All issued and outstanding common stock and per share amounts contained in the financial statements have been retroactively adjusted to reflect this Reverse Stock Split for all periods presented. In addition, a proportionate adjustment was made to the per share exercise price and the number of shares issuable upon the exercise and/or vesting of all outstanding stock options, restricted stock units and warrants to purchase shares of common stock. A proportionate adjustment was also made to the number of shares reserved for issuance pursuant to the Company’s equity incentive compensation plans to reflect the Reverse Stock Split. Any fraction of a share of common stock that was created as a result of the Reverse Stock Split was rounded up to the next whole share. The common stock par value and additional paid-in-capital line items contained in the financial statements were adjusted to account for the Reverse Stock Split for all periods presented.

Basis for presentation. These consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and the rules and regulations of the Securities and Exchange Commission. In the opinion of management, these consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of results for such periods.

Related Party Transactions. A related party transaction is any transaction, arrangement or relationship or series of similar transactions, arrangements or relationships (including the incurrence or issuance of any indebtedness or the guarantee of indebtedness) in which (1) the Company or any of its subsidiaries is a participant, and (2) any Related Party (as defined herein) has or will have a direct or indirect material interest.

A related party is any person who is, or, at any time since the beginning of the Company’s last fiscal year, was (1) an executive officer, director or nominee for election as a director of the Company or any of its subsidiaries, (2) a person with greater than five percent (5%) beneficial interest in the Company, (3) an immediate family member of any of the individuals or entities identified in (1) or (2) of this paragraph, and (4) any firm, corporation or other entity in which any of the foregoing individuals or entities is employed or is a general partner or principal or in a similar position or in which such person or entity has a five percent (5%) or greater beneficial interest. Immediate family members includes a person’s spouse, parents, stepparents, children, stepchildren, siblings, mothers- and fathers-in-law, sons- and daughters-in-law, brothers- and sisters-in-law and anyone residing in such person’s home, other than a tenant or employee.

Liquidity and Going Concern. These consolidated financial statements have been prepared in accordance with GAAP and assuming the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the issue date of these consolidated financial statements. Our ability to continue as a going concern is dependent on many factors, including among other things, our ability to comply with the covenants in our debt agreements, our ability to cure any defaults that occur under our debt agreements, or forbearances with respect to any such defaults, and our ability to pay, retire, amend, replace or refinance our indebtedness as defaults occur or as interest and principal payments come due. Liquidity risk is the risk that we will be unable to meet our financial obligations as they become due. Our liquidity may be affected by improvements and declines in commodity prices, our segments’ operational performance, and our ability to access capital and credit markets.

We evaluated our liquidity within one year after the date of issuance of these audited consolidated financial statements to determine if there is substantial doubt about the Company’s ability to continue as a going concern. In the preparation of this liquidity assessment, we applied judgment to estimate the projected cash flows of the Company, including the following: (i) projected cash outflows, (ii) projected cash inflows, and (iii) projected availability under the Company’s existing debt arrangements. The cash flow projections were based on known or planned cash requirements for operating and financing costs and include management’s best estimate regarding future customer activity levels, pricing for its services and for its supplies and other factors. Actual results could vary significantly from those projections. We do not believe, based on the Company’s forecast, that current working capital, cash flow from operations, expected availability under our existing credit agreements and capital expenditure financing is sufficient to fund the operations, maintain compliance with our debt covenants (as amended), and satisfy the Company’s obligations, specifically with respect to the Notes described below, as they come due within one year after the date of issuance of these consolidated financial statements.

Our Notes are due on August 1, 2023 and had a principal balance of $41.2 million as of December 31, 2022 following the exchanged transactions described in Note 12 - Debt. We are exploring alternatives to reduce or refinance the Notes outstanding balance, including extending their maturity as well as other alternatives. There is no assurance that we will be able to execute a reduction, extension, or refinancing of the Notes or that the terms of any replacement financing would be as favorable as the terms of the Notes prior to the maturity date. Under the terms of our amended financing arrangements that were entered into during 2022, the Maturity Reserve Trigger Date (as defined in the 2022 ABL Credit Agreement), and the Maturity Trigger Date (as defined in the Term Loan Credit Agreement) collectively referred to as the “Trigger Date” is June 17, 2023, see Note 12 - Debt for additional information. Therefore, the Notes balance must be paid down to less than $10.0 million by June 17, 2023.

On October 4, 2022, we entered into Amendment No. 8 (“Corre Amendment 8”) to the Subordinated Term Loan Credit Agreement. On November 1, 2022, we completed the Quest Integrity Transaction with Baker Hughes, as discussed above, for an aggregate purchase price of approximately $279.0 million, after certain post-closing adjustments, in accordance with the Sale Agreement. On November 4, 2022, we entered into Amendment No. 9 (“Term Loan Amendment No. 9”) to the Term Loan Credit Agreement and Amendment No. 10 (“Corre Amendment 10”) to the Subordinated Term Loan Credit Agreement. Refer to Note 12 - Debt for more information on the terms, maturity dates and amendments to our debt that may affect our future liquidity.

As of December 31, 2022, we are in compliance with our debt covenants. Without the execution of a refinancing transaction, an agreement to extend the Notes maturity date, and/or amendments to our existing debt agreements there is a risk that the Company could be, among other things, unable to make principal payments on the Notes to satisfy the Trigger Date provision or will be unable to pay off the Notes when they become due on August 1, 2023. The failure to pay down the Notes to less than $10.0 million would (i) trigger the early maturity of our Term Loan Credit Agreement pursuant to the Trigger Date concept, and (ii) permit the administrative agent under the 2022 ABL Credit Agreement to implement a borrowing base reserve in an amount equal to the outstanding principal amount of the Notes on such date. A required repayment of the Term Loan Credit Agreement in accordance with the Trigger Date concept would in turn trigger a requirement to repay the Subordinated Term Loans pursuant to the Subordinated Term Loan Credit Agreement 14 days after repayment in full of the Term Loan Credit Agreement. There is no assurance that we would be able to make such payments, and failure to make such payments would result in events of default under the applicable credit facility and associated cross defaults under the Company’s other debt instruments. Failure to pay the Notes off at the maturity date on August 1, 2023 will result in an event of default under the Notes and the associated cross defaults noted above under the Company’s other debt instruments. Refer to Note 12 - Debt for more information on the terms and maturity dates of our debt that may affect our future liquidity.

Our ability to maintain compliance with the financial covenants contained in the 2022 ABL Credit Agreement, the Term Loan Credit Agreement and the Subordinated Term Loan Credit Agreement is dependent upon our future operating performance and future financial condition, both of which are subject to various risks and uncertainties. The lingering effects of COVID-19, threat of recession and resulting economic repercussions could have a significant adverse effect on our financial position and business condition, as well as our clients and suppliers. Additionally, these events may, among other factors, impact our ability to generate cash flows from operations, access the capital markets on acceptable terms or at all, and affect our future need or ability to borrow under our 2022 ABL Credit Facility. In addition to our current sources of funding our business,

the effects of such events may impact our liquidity or our need to revise our allocation or sources of capital, implement further cost reduction measures and/or change our business strategy. Political economic repercussions could have a broad range of effects on our liquidity sources and will depend on future developments and cannot be predicted at this time.

As a result of our current liquidity condition and the potential inability to negotiate an extension or amend the financial covenants, substantial doubt about the Company’s ability to continue as a going concern is raised. We are evaluating and will continue to explore strategic alternatives to a refinancing transaction or the reduction of the debt, including negotiating amendments to our credit facilities and the financial covenants contained therein, the sale of assets, or other alternative financing transactions. While our lenders agreed on an extension and amended the financial covenants in prior periods, there can be no assurance that our lenders will provide additional extensions, waivers or amendments in the event of future non-compliance with our debt covenants, or other possible events of default. As such, substantial doubt exists about our ability to continue as a going concern. The consolidated financial statements do not include any adjustments to the carrying amounts and classification of assets, liabilities, and reported expenses that may be necessary if the Company were unable to continue as a going concern.

Use of estimates. Our accounting policies conform to Generally Accepted Accounting Principles (“GAAP”) in the United States. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and judgments that affect our reported financial position and results of operations. We review significant estimates and judgments affecting our consolidated financial statements on a recurring basis and record the effect of any necessary adjustments prior to their publication. Estimates and judgments are based on information available at the time such estimates and judgments are made. Adjustments made with respect to the use of these estimates and judgments often relate to information not previously available. Uncertainties with respect to such estimates and judgments are inherent in the preparation of financial statements. Estimates and judgments are used in, among other things, (1) valuation of acquisition related tangible and intangible assets and assessments of all long-lived assets for possible impairment, (2) estimating various factors used to accrue liabilities for workers’ compensation, auto, medical and general liability, (3) establishing an allowance for uncollectible accounts receivable, (4) estimating the useful lives of our assets, (5) assessing future tax exposure and the realization of tax assets, (6) selecting assumptions used in the measurement of costs and liabilities associated with defined benefit pension plans, (7) assessments of fair value and (8) managing our foreign currency risk in foreign operations. Our most significant accounting policies are described below.

Fair value of financial instruments. As defined in FASB ASC 820 Fair Value Measurements and Disclosure (“ASC 820”), fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or generally unobservable. We primarily apply the market approach for recurring fair value measurements and endeavor to utilize the best information available. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The use of unobservable inputs is intended to allow for fair value determinations in situations in which there is little, if any, market activity for the asset or liability at the measurement date. We are able to classify fair value balances based on the observability of those inputs. ASC 820 establishes a fair value hierarchy such that “Level 1” measurements include unadjusted quoted market prices for identical assets or liabilities in an active market, “Level 2” measurements include quoted market prices for identical assets or liabilities in an active market which have been adjusted for items such as effects of restrictions for transferability and those that are not quoted but are observable through corroboration with observable market data, including quoted market prices for similar assets, and “Level 3” measurements include those that are unobservable and of a highly subjective measure.

Our financial instruments consist primarily of cash, cash equivalents, accounts receivable, accounts payable, pension assets and debt obligations. The carrying amount of cash, cash equivalents, trade accounts receivable and trade accounts payable are representative of their respective fair values due to the short-term maturity of these instruments. For additional information regarding our pension assets, see Note 16 - Employee Benefit plan. The fair value of our 2022 ABL Credit Facility and Term Loans are representative of the carrying value based upon the variable terms and management’s opinion that the current rates available to us with the same maturity and security structure are equivalent to that of the debt. The fair value of the Notes as of December 31, 2022 and 2021 was $37.5 million and $84.0 million, respectively, (inclusive of the fair value of the conversion option) and are a “Level 2” measurement, determined based on the observed trading price of these instruments. For additional information regarding our 2022 ABL Credit Facility, Term Loan, Subordinated Term Loan and Notes, see Note 12 - Debt.

Inventory. Except for certain inventories that are valued based on standard cost, we use the first-in, first-out method to value our inventory. Inventory includes material, labor, and certain fixed overhead costs. Inventory is stated at the lower of cost and net realizable value. Inventory quantities on hand are reviewed periodically and carrying value is reduced to net realizable

Property, plant and equipment. Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Leasehold improvements are amortized over the shorter of their respective useful life or the lease term. Depreciation and amortization of assets are computed by the straight-line method over the following estimated useful lives of the assets:

Goodwill and intangible assets. Goodwill and intangible assets acquired in a business combination determined to have an indefinite useful life are not amortized, but are instead tested for impairment, and assessed for potential triggering events, at least annually in accordance with the provisions of the ASC 350 Intangibles—Goodwill and Other (“ASC 350”). Intangible assets with finite lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment in accordance with ASC 360-10 Impairment or Disposal of Long-Lived Assets (“ASC 360”).

We assess goodwill for impairment at the reporting unit level, which we have determined to be the same as our operating segments. If the carrying value of a reporting unit exceeds its fair value, we measure any goodwill impairment losses as the amount by which the carrying amount of a reporting unit exceeds its fair value, not to exceed the total amount of goodwill allocated to that reporting unit.

During the year ended December 31, 2021, our assessment of qualitative indicators associated with our interim and annual goodwill impairment tests indicated a potential impairment existed. The next step of goodwill assessment determined that an impairment existed as the carrying value of the MS segment exceeded its fair value. As a result, we recorded goodwill impairment of $55.8 million during the year ended December 31, 2021. We also recorded goodwill impairment of $8.8 million on our discontinued operations during the year ended December 31, 2021. There was no goodwill impairment recorded during or as of December 31, 2022.

Impairment of Long-lived Assets. The Company reviews its property and equipment, intangible assets subject to amortization and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset class may not be recoverable. Indicators of potential impairment include: an adverse change in legal factors or in the business climate that could affect the value of the asset; an adverse change in the extent or manner in which the asset is used or is expected to be used, or in its physical condition; and current or forecasted operating or cash flow losses that demonstrate continuing losses associated with the use of the asset. If indicators of impairment are present, the asset is tested for recoverability by comparing the carrying value of the asset to the related estimated undiscounted future cash flows expected to be derived from the asset. If the expected cash flows are less than the carrying value of the asset, then the asset is considered to be impaired and its carrying value is written down to fair value, based on the related estimated discounted cash flows. There were no impairment charges in 2022 or 2021.

Income taxes. We follow the guidance of ASC 740 Income Taxes (“ASC 740”), which requires that we use the asset and liability method of accounting for deferred income taxes and provide deferred income taxes for all significant temporary differences. As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax payable or receivable and related tax expense or benefit together with assessing temporary differences resulting from differing treatment of certain items such as depreciation for tax and accounting purposes. These differences can result in deferred tax assets and liabilities, which are included within our consolidated balance sheets.

In accordance with ASC 740, we are required to assess the likelihood that our deferred tax assets will be realized and, to the extent we believe it is more likely than not (a likelihood of more than 50%) that some portion or all of the deferred tax assets will not be realized, we must establish a valuation allowance. We consider all available evidence to determine whether, based on the weight of the evidence, a valuation allowance is needed. Evidence used includes the reversal of existing taxable

temporary differences, taxable income in prior carryback years if carryback is permitted by tax law, information about our current financial position and our results of operations for the current and preceding years, as well as all currently available information about future years, including our anticipated future performance and tax planning strategies.

We regularly assess whether it is more likely than not that we will realize the deferred tax assets in the jurisdictions we operate in. Management believes future sources of taxable income, reversing temporary differences and other tax planning strategies will be sufficient to realize the deferred tax assets for which no valuation allowance has been established. Our valuation allowance primarily relates to net operating loss carryforwards. While we have considered these factors in assessing the need for additional valuation allowance, there is no assurance that additional valuation allowance would not need to be established in the future if information about future years change. Any changes in valuation allowance would impact our income tax provision and net income (loss) in the period in which such a determination is made. As of December 31, 2022, our deferred tax assets were $94.7 million, less a valuation allowance of $73.5 million. As of December 31, 2022, our deferred tax liabilities were $24.5 million.

Significant judgment is required in assessing the timing and amounts of deductible and taxable items for tax purposes. In accordance with ASC 740-10, we establish reserves for uncertain tax positions when, despite our belief that our tax return positions are supportable, we believe that it is not more likely than not that the position will be sustained upon challenge. When facts and circumstances change, we adjust these reserves through our provision for income taxes. To the extent interest and penalties may be assessed by taxing authorities on any related underpayment of income tax, such amounts have been accrued and are classified as a component of income tax expense (benefit) in our consolidated statements of operations. As of December 31, 2022, our gross unrecognized tax benefits, excluding penalties and interest related to uncertain tax positions, were $1.1 million.

Workers’ compensation, auto, medical and general liability accruals. In accordance with ASC 450 Contingencies (“ASC 450”), we record a loss contingency when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. We review our loss contingencies on an ongoing basis to ensure that we have appropriate reserves recorded on our balance sheet. These reserves are based on historical experience with claims incurred but not received, estimates and judgments made by management, applicable insurance coverage for litigation matters, and are adjusted as circumstances warrant. For workers’ compensation, our self-insured retention is $1.0 million and our automobile liability self-insured retention is currently $2.0 million per occurrence. For professional liability claims, our self-insured retention is $2.0 million. For general liability claims, we have a self-insured retention of $1.0 million and a deductible of $4.0 million per occurrence. For environmental liability claims, our self-insured retention is $1.0 million per occurrence. We maintain insurance for claims that exceed such self-retention limits. For medical claims, our self-insured retention is $350,000 per individual claimant determined on an annual basis. The insurance is subject to terms, conditions, limitations, and exclusions that may not fully compensate us for all losses. Our estimates and judgments could change based on new information, changes in laws or regulations, changes in management’s plans or intentions, or the outcome of legal proceedings, settlements, or other factors. If different estimates and judgments were applied with respect to these matters, it is likely that reserves would be recorded for different amounts.

Allowance for credit losses. In the ordinary course of business, a portion of our accounts receivable are not collected due to billing disputes, customer bankruptcies or other various reasons. We establish an allowance to account for those accounts receivable that we estimate will eventually be deemed uncollectible. The allowance for credit losses is based on a combination of our historical experience and management’s review of long outstanding accounts receivable.

Accounting for Warrants. The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

As of December 31, 2022 and 2021, we had equity-classified warrants that were issued in connection with our APSC Term Loan and Subordinated Term Loan Credit Agreement (see Note 12 - Debt). The warrants were accounted for as a component of additional paid-in capital and a debt warrant discount. The warrant discount was being amortized over the term of the debt. As of December 31, 2022 and 2021, an unamortized balance of warrant discount amounted to $3.3 million and $29.2 million, respectively.

Earnings (loss) per share. Basic earnings (loss) per share is computed by dividing income (loss) from continuing operations, income (loss) from discontinued operations or net income (loss) by the weighted-average number of shares of common stock outstanding during the year. Diluted earnings (loss) per share is computed by dividing income (loss) from continuing operations, income (loss) from discontinued operations or net income (loss) by the sum of (1) the weighted-average number of shares of common stock outstanding during the period, (2) the dilutive effect of the assumed exercise of share-based compensation using the treasury stock method and (3) the dilutive effect of the assumed conversion of our Notes under the treasury stock method. Our current intent is to settle the principal amount of our Notes in cash upon conversion. If the conversion value exceeds the principal amount, we may elect to deliver shares of our common stock with respect to the remainder of our conversion obligation in excess of the aggregate principal amount (the “conversion spread”). Accordingly, the conversion spread is included in the denominator for the computation of diluted earnings per common share using the treasury stock method and the numerator is adjusted for any recorded gain or loss, net of tax, on the embedded derivative associated with the conversion feature.

For the years ended December 31, 2022, and 2021, all outstanding share-based compensation awards were excluded from the calculation of diluted loss per share because their inclusion would be antidilutive due to the loss from continuing operations in those periods. Also, the effect of our Notes was excluded from the calculation of diluted earnings (loss) per share since the conversion price exceeded the average price of our common stock during the applicable periods. For information on our Notes and our share-based compensation awards, refer to Note 12 - Debt and Note 14 - Share-Based Compensation, respectively.

Foreign currency. For subsidiaries whose functional currency is not the U.S. dollar, assets and liabilities are translated at period ending rates of exchange and revenues and expenses are translated at period average exchange rates. Translation adjustments for the asset and liability accounts are included as a separate component of accumulated other comprehensive loss in stockholders’ equity. Foreign currency transaction gains and losses are included in our statements of operations.

We have historically executed a foreign currency hedging program to mitigate the foreign currency risk in countries where we have significant assets and liabilities denominated in currencies other than the functional currency. Our hedging program ended in October 2021. The impact from the foreign currency swap contracts was not material for the year ended December 31, 2022 or 2021.

Defined benefit pension plans. Pension benefit costs and liabilities are dependent on assumptions used in calculating such amounts. The primary assumptions include factors such as discount rates, expected investment return on plan assets, mortality rates and retirement rates. These rates are reviewed annually and adjusted to reflect current conditions. These rates are determined based on reference to yields. The expected return on plan assets is derived from detailed periodic studies, which include a review of asset allocation strategies, anticipated future long-term performance of individual asset classes, risks (standard deviations) and correlations of returns among the asset classes that comprise the plans’ asset mix. While the studies give appropriate consideration to recent plan performance and historical returns, the assumptions are primarily long-term, prospective rates of return. Mortality and retirement rates are based on actual and anticipated plan experience. In accordance with GAAP, actual results that differ from the assumptions are accumulated and are subject to amortization over future periods and, therefore, generally affect recognized expense in future periods. While we believe that the assumptions used are appropriate, differences in actual experience or changes in assumptions may affect the pension obligation and future expense.

ASU No. 2020-06. In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, (“ASU 2020-06”), which simplifies the accounting for convertible instruments by eliminating certain separation models and will generally be reported as a single liability at its amortized cost. In addition, ASU 2020-06 eliminates the treasury stock method to calculate diluted earnings per share for convertible instruments and requires the use of the if-converted method. On January 1, 2022, we adopted this ASU using the modified retrospective method. We recognized a cumulative effect of initially applying this ASU as an adjustment to the January 1, 2022 opening accumulated deficit balance. The prior period consolidated financial statements have not been retrospectively adjusted and continue to be reported under the accounting standards in effect for those periods. Refer to Note 12 - Debt for impact on the adoption of this ASU as of January 1, 2022.

ASU No. 2020-04. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, (“ASU 2020-04”). The guidance in ASU 2020-04 and ASU 2021-01, Reference Rate Reform (Topic 848): Scope, which was issued in January 2021, provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria that reference the London Interbank Offered Rate, (“LIBOR”), or another rate that is expected to be discontinued. The amendments in ASU 2020-04 are effective for all entities as of March 12, 2020 through December 31, 2022. On December 21, 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848) Deferral of the Sunset Date of Topic 848 which defers the sunset date of ASC 848, Reference Rate Reform, from December 31, 2022, to December 31, 2024. While we are currently determining whether we will elect the optional expedients, we do not expect our adoption of these ASU’s to have a significant impact on our consolidated financial position, results of operations, and cash flows.
