- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Organization and Principles of Consolidation. Newpark Resources, Inc. was organized in 1932 as a Nevada corporation. In 1991, we changed our state of incorporation to Delaware. The consolidated financial statements include our company and our wholly-owned subsidiaries (the “Company,” “we,” “our,” or “us”). All intercompany transactions are eliminated in consolidation.

We are a geographically diversified supplier providing environmentally-sensitive products, as well as rentals and services to customers across multiple industries. We currently operate our business through two reportable segments: Fluids Systems and Industrial Solutions. In addition, we had a third reportable segment, Industrial Blending, which was exited in 2022. Prior to 2022, we aggregated our now exited Industrial Blending business and reported it within Industrial Solutions. We have reflected these three reportable segments for all periods presented in this Annual Report on Form 10-K.

•Our Fluids Systems segment provides customized drilling, completion, and stimulation fluids products and related technical services to oil and natural gas exploration and production (“E&P”) customers primarily in North America and Europe, the Middle East and Africa (“EMEA”), as well as certain countries in Asia Pacific and Latin America.

•Our Industrial Solutions segment provides temporary worksite access solutions, including the rental of our recyclable composite matting systems, along with related site construction and services to customers in various markets including power transmission, E&P, pipeline, renewable energy, petrochemical, construction and other industries, primarily in the United States and Europe. We also manufacture and sell our recyclable composite mats to customers around the world, with power transmission being the primary end-market.

•Our Industrial Blending segment began operations in 2020 and supported industrial end-markets, including the production of disinfectants and industrial cleaning products. We completed the wind down of the Industrial Blending business in the first quarter of 2022, and we completed the sale of the industrial blending and warehouse facility and related equipment located in Conroe, Texas in the fourth quarter of 2022.

Use of Estimates and Market Risks. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates used in preparing our consolidated financial statements include, but are not limited to, the following: estimated cash flows and fair values used for impairments of long-lived assets, including goodwill and other intangibles, and valuation allowances for deferred tax assets.

Our Fluids Systems operating results remain dependent on oil and natural gas drilling activity levels in the markets we serve and the nature of the drilling operations (including the depth and whether the wells are drilled vertically or horizontally), which governs the revenue potential of each well. Drilling activity levels, in turn, depend on a variety of factors, including oil and natural gas commodity pricing, inventory levels, product demand, and regulatory restrictions. Oil and natural gas prices and activity are cyclical and volatile, and this market volatility has a significant impact on our operating results.

Cash Equivalents. All highly liquid investments with a remaining maturity of three months or less at the date of acquisition are classified as cash equivalents.

Restricted Cash. Cash that is restricted as to withdrawal or usage is recognized as restricted cash and is included in other current assets in the consolidated balance sheets.

Allowance for Credit Losses. Trade receivables are presented at the net amount expected to be collected. We estimate the lifetime “expected credit loss” for such assets at inception, which generally results in the earlier recognition of allowances for losses. Our allowance for credit losses reflects losses that are expected over the contractual life of the asset, and takes into account historical loss experience, current and future economic conditions, and reasonable and supportable forecasts.

Inventories. Inventories are stated at the lower of cost (principally average cost) or net realizable value. Certain conversion costs associated with the acquisition, production, blending, and storage of inventory in our Fluids Systems segment as well as the manufacturing operations in the Industrial Solutions segment are capitalized as a component of the carrying value of the inventory and expensed as a component of cost of revenues as the products are sold. Reserves for inventory obsolescence are determined based on the net realizable value of the inventory using factors such as our historical usage of inventory on-hand, future expectations related to our customers’ needs, market conditions, and the development of new products.

Property, Plant and Equipment. Property, plant and equipment are recorded at cost. Additions and improvements that extend the useful life of an asset are capitalized. We capitalize interest costs on significant capital projects. Maintenance and repairs are expensed as incurred. Sales and disposals of property, plant and equipment are removed at carrying cost less accumulated depreciation with any resulting gain or loss reflected in earnings.

Depreciation is provided on property, plant and equipment, including finance lease assets, primarily utilizing the straight-line method over the following estimated useful service lives or lease term:


Computer hardware and office equipment		3-5 years
Computer software		3-5 years
Autos and light trucks		5-7 years
Furniture, fixtures, and trailers		7-10 years
Composite mats (rental fleet)		7-12 years
Machinery and heavy equipment		10-15 years
Owned buildings		20-39 years
Leasehold improvements	Lease term, including reasonably assured renewal periods

Goodwill and Other Intangible Assets. Goodwill represents the excess of the purchase price of acquisitions over the fair value of the net identifiable assets acquired in business combinations. Goodwill and other intangible assets with indefinite lives are not amortized. Intangible assets with finite useful lives are amortized either on a straight-line basis over the asset’s estimated useful life or on a basis that reflects the pattern in which the economic benefits of the asset are realized. Any period costs of maintaining intangible assets are expensed as incurred.

Impairment of Long-Lived Assets. Goodwill and other indefinite-lived intangible assets are tested for impairment annually as of November 1, or more frequently, if indicators of impairment exist. As part of our annual goodwill review, we first perform a qualitative assessment based on company performance and future business outlook to determine if indicators of impairment exist. When there are qualitative indicators of impairment, we use an impairment test which includes a comparison of the carrying value of net assets of our reporting units, including goodwill, with their estimated fair values, which we estimate using a combination of a market multiple and discounted cash flow approach (classified within level 3 of the fair value hierarchy). If the carrying value exceeds the estimated fair value, an impairment charge is recorded in the period in which such review is performed. We identify our reporting units based on our analysis of several factors, including our operating segment structure, evaluation of the economic characteristics of our geographic regions within each of our operating segments, and the extent to which our business units share assets and other resources.

We review property, plant and equipment, finite-lived intangible assets and certain other assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. We assess recoverability based on the undiscounted future net cash flows expected from the use and eventual disposition of such asset. Should the review indicate that the carrying value is not fully recoverable, the amount of impairment loss is determined by comparing the carrying value to the estimated fair value.

Insurance. We maintain reserves for estimated future payments associated with our self-insured employee healthcare programs, as well as the self-insured retention exposures under our general liability, auto liability, and workers compensation insurance policies. Our reserves are determined based on historical experience under these programs, including estimated development of known claims and estimated incurred-but-not-reported claims.

Treasury Stock. Treasury stock is carried at cost, which includes the entire cost of the acquired stock.

Revenue Recognition. The following provides a summary of our significant accounting policies for revenue recognition.

Fluids Systems. Revenues for fluid system additive products and engineering services, when provided to customers in the delivery of an integrated fluid system, are recognized as product sales revenues when utilized by the customer. Revenues for formulated liquid systems are recognized as product sales revenues when utilized or lost downhole while drilling. Revenues for equipment rentals and other services provided to customers that are ancillary to the fluid system product delivery are recognized in rental and service revenues when the services are performed. For direct sales of fluid system products, revenues are recognized when control passes to the customer, which is generally upon shipment of materials.

Industrial Solutions. Revenues for rentals and services are generated from both fixed-price and unit-priced contracts, which are generally short-term in duration. The activities under these contracts include the installation and rental of matting

systems for a period of time and services such as access road construction, site planning and preparation, environmental protection, erosion control, and site restoration services. Rental revenues are recognized over the rental term and service revenues are recognized when the specified services are performed. Revenues from any subsequent extensions to the rental agreements are recognized over the extension period. Revenues from the direct sale of products are recognized when control passes to the customer, which is upon shipment or delivery, depending on the terms of the underlying sales contract.

For all segments, the amount of revenue we recognize for products sold and services performed reflects the consideration to which we expect to be entitled in exchange for such goods or services, which generally reflects the amount we have the right to invoice based on agreed upon unit rates. While billing requirements vary, many of our customer contracts require that billings occur periodically or at the completion of specified activities, even though our performance and right to consideration occurs throughout the contract. As such, we recognize revenue as performance is completed in the amount to which we have the right to invoice. We do not disclose the value of our unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue for the amount to which we have the right to invoice for products sold and services performed.

Shipping and handling costs are reflected in cost of revenues, and all reimbursements by customers of shipping and handling costs are included in revenues.

Income Taxes. We provide for deferred taxes using an asset and liability approach by measuring deferred tax assets and liabilities due to temporary differences existing at year end using currently enacted tax rates and laws that will be in effect when the differences are expected to reverse. We reduce deferred tax assets by a valuation allowance when, based on our estimates, it is more likely than not that a portion of those assets will not be realized in a future period. The estimates utilized in recognition of deferred tax assets are subject to revision, either up or down, in future periods based on new facts or circumstances. We present deferred tax assets and liabilities as noncurrent in the balance sheet based on an analysis of each taxpaying component within a jurisdiction. We evaluate uncertain tax positions and record a liability as circumstances warrant.

Share-Based Compensation. Share-based compensation cost is measured at the grant date based on the fair value of the award, net of an estimated forfeiture rate. We recognize these costs in the statement of operations using the straight-line method over the vesting term.

Foreign Currency Translation. The functional currency for substantially all international subsidiaries is their respective local currency. Financial statements for these international subsidiaries are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities and the average exchange rates in effect during the respective period for revenues and expenses. Exchange rate adjustments resulting from translation of foreign currency financial statements of our international subsidiaries are reflected in accumulated other comprehensive loss in stockholders’ equity until such time that the international subsidiary is sold or liquidation is substantially complete, at which time the related accumulated adjustments would be reclassified into income. Exchange rate adjustments resulting from foreign currency denominated transactions are recorded in income. At December 31, 2022 and 2021, accumulated other comprehensive loss related to foreign subsidiaries reflected in stockholders’ equity was $67.2 million and $61.5 million, respectively.

During the fourth quarter of 2019, we made the decision to wind down our Brazil operations, and during the fourth quarter of 2020, we completed the substantial liquidation of our Brazil subsidiary and recognized an $11.7 million non-cash charge to "impairments and other charges" for the reclassification of cumulative foreign currency translation losses related to our subsidiary in Brazil.

Fair Value Measurement. Fair value is measured as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at a measurement date. We apply the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

•Level 1: The use of quoted prices in active markets for identical financial instruments.

•Level 2: The use of quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active or other inputs that are observable in the market or can be corroborated by observable market data.

•Level 3: The use of significantly unobservable inputs that typically require the use of management’s estimates of assumptions that market participants would use in pricing.

New Accounting Pronouncements

Standards Adopted in 2021

Income Taxes: Simplifying the Accounting for Income Taxes. In 2019, the FASB issued new guidance intended to simplify various aspects related to accounting for income taxes. We adopted this new guidance as of January 1, 2021. The adoption of this new guidance had no material impact on our financial statements or related disclosures.

Standards Adopted in 2020

Credit Losses: In 2016, the FASB issued new guidance which requires financial assets measured at amortized cost basis, including trade receivables, to be presented at the net amount expected to be collected. We adopted this new guidance as of January 1, 2020 using the modified retrospective transition method, and recorded a net reduction of $0.7 million to opening retained earnings to reflect the cumulative effect of adoption. The cumulative effect of the changes made to our consolidated balance sheet for the adoption of the new accounting guidance for credit losses were as follows:


(In thousands)	Balance at December 31, 2019		Impact of Adoption of New Credit Losses Guidance		Balance at January 1, 2020
Receivables, net	$	216,714	$	(959)	$	215,755
Deferred tax assets	3,600		59		3,659
Deferred tax liabilities	34,247		(165)		34,082
Retained earnings	134,119		(735)		133,384

Business Combination and Asset Acquisition [Abstract]

Divestitures and Business Combinations

Divestitures

Throughout the oil and natural gas cycle of the last couple of years, we continuously reviewed our portfolio. These reviews have focused on evaluating changes in the outlook for our served markets and customer priorities, while identifying opportunities for value-creating options in our portfolio, placing investment emphasis in markets where we generate strong returns and where we see greater long-term viability and stability. As part of this review, our Board of Directors approved the following actions in 2022.

Exit of Industrial Blending Segment and Sale of Conroe, Texas Blending Facility

In the first quarter of 2022, in consideration of broader strategic priorities and the timeline and efforts required to further develop the industrial blending business, we exited our Industrial Blending operations. In November 2022, we completed the sale of the industrial blending and warehouse facility and related equipment located in Conroe, Texas to a global chemical provider, and received cash proceeds of approximately $14 million. In connection with this divestiture, we recognized a $7.9 million impairment charge related to these long-lived assets in the second quarter of 2022, and subsequently recognized a gain of $2.6 million upon the eventual sale in the fourth quarter of 2022.

Sale of Excalibar U.S. Mineral Grinding Business

In the second quarter of 2022, we initiated a formal sale process for our Excalibar U.S. mineral grinding business (“Excalibar”), which is reported within our Fluids Systems segment. On November 30, 2022, we completed the sale of substantially all the long-lived assets, inventory, and operations of Excalibar to Cimbar Resources, INC. (“Cimbar”), received cash proceeds (after purchase price adjustments) of approximately $51 million, and recognized a gain of $1.0 million. The Company retained certain assets and liabilities, including accounts receivable and accounts payable. Such working capital provided approximately $10 million of cash generation in the fourth quarter of 2022 and is expected to provide approximately $5 million of additional cash generation in early 2023. In connection with the sale, the Company and Cimbar have entered into a long-term barite supply agreement for certain regions of our U.S. drilling fluids business, with an initial term of four years following the closing of the transaction.

Exit of Gulf of Mexico Operations

In the third quarter of 2022, our Board of Directors approved management’s plan to exit our Fluids Systems Gulf of Mexico operations, including the potential sale of related assets. In December 2022, we completed the sale of substantially all assets associated with our Gulf of Mexico completion fluids operations. Separately, we also entered a seven-year arrangement to sublease our Fourchon, Louisiana drilling fluids shorebase and blending facility to a leading global energy services provider. As part of this arrangement, substantially all of our Gulf of Mexico drilling fluids inventory will be sold as consumed by the lessee or no later than nine months from the closing of the transaction. The sale of the completion fluids operations provided approximately $6 million of cash generation in the fourth quarter of 2022, and the exit of the drilling fluids operations is expected to provide approximately $25 million of additional cash generation, primarily in early 2023.

As a result of the plan to exit the Gulf of Mexico operations as described above, we considered the third quarter developments to be a potential indicator of impairment that required us to complete an impairment evaluation. Accordingly, we estimated the fair value for our Gulf of Mexico assets as of September 30, 2022 based on the expected cash flows to be generated from the anticipated transactions and determined that a $21.5 million impairment charge was required related to the long-lived assets. We also recognized an $8.0 million charge to reduce the carrying value of inventory to their net realizable value primarily based on the anticipated transactions. The total charges of $29.4 million were recorded to impairments and other charges in the third quarter of 2022.

Total impairments and other charges consisted of the following:


	Year Ended December 31,
(In thousands)	2022
Industrial Blending - Long-lived assets impairment	$	7,905
Gulf of Mexico - Long-lived assets impairment	21,461
Gulf of Mexico - Inventory write-downs	7,956
Total impairments and other charges	$	37,322

Summarized operating results of the business units exited in 2022 (including impairments and other charges described above) are shown in the following table:


	Year Ended December 31,
(In thousands)	2022		2021		2020

Property, plant and equipment, net	4,508		74,318
Accounts payable	(2,060)		(5,136)
Accrued liabilities	(311)		(1,976)
Total net assets	$	35,740	$	121,767

As described above, the change in net assets related to these divested business units includes the impact of the $37.3 million of impairments and other charges, the impact from the divestiture transactions, as well as the wind-down of retained working capital. The net assets remaining as of December 31, 2022 relate to the remaining Gulf of Mexico net assets and retained working capital from the Excalibar sale. As noted above, we expect to generate approximately $31 million of cash primarily in the first half of 2023 from the realization of the remaining working capital related to these divestitures.

Business Combinations

In December 2021, we acquired certain assets and assumed certain liabilities of Lentzcaping, Inc. and Lentzcaping, LLC (together, "Lentzcaping"). The purchase price for this acquisition was $13.5 million, net of cash acquired, and was funded with borrowings under the ABL Facility (as defined in Note 6). The results of operations of Lentzcaping are reported within the Industrial Solutions segment for the periods subsequent to the date of the acquisition. Results of operations and pro-forma combined results of operations for the acquired business have not been presented as the effect of this acquisition is not material to our consolidated financial statements.

Inventories

Inventories consisted of the following at December 31:


(In thousands)	2022		2021
Raw materials:
Fluids Systems	$	110,623	$	119,242
Industrial Solutions	3,966		4,939
Total raw materials	114,589		124,181
Blended fluids systems components	29,244		27,793
Finished goods — mats	5,738		3,367
Total inventories	$	149,571	$	155,341

Raw materials for the Fluids Systems segment consist primarily of chemicals and other additives that are consumed in the production of our fluids systems. Raw materials for the Industrial Solutions segment consist primarily of resins, chemicals, and other materials used to manufacture composite mats, as well as materials that are consumed in providing ground protection and other services to our customers. Our blended fluids systems components consist of base fluids systems that have been either mixed internally at our blending facilities or purchased from third-party vendors. These base fluids systems require raw materials to be added, as needed to meet specified customer requirements.

The decrease in inventories in 2022 was primarily attributable to a $36.6 million decrease related to our divestitures described in Note 2, including the impact of related inventory impairments, partially offset by activity-driven increases and raw materials cost inflation in the Fluids Systems segment.

The Fluids Systems segment operating results for 2022 includes $8.0 million of total charges for inventory write-downs included in impairments and other charges, primarily attributable to the reduction in carrying values of certain inventory related to the exit of our Gulf of Mexico operations to their net realizable value.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Other Intangible Assets

Changes in the carrying amount of goodwill, which all relates to the Industrial Solutions segment, are as follows:


(In thousands)	Industrial Solutions
Balance at December 31, 2020	$	42,444

Asset-Based Loan Facility. In October 2017, we entered into a U.S. asset-based revolving credit agreement, which was amended in March 2019 (the “ABL Facility”). In May 2022, we amended and restated the ABL Facility (the “Amended ABL Facility”). The Amended ABL Facility provides financing of up to $175.0 million available for borrowings (inclusive of letters of credit), which can be increased up to $250.0 million, subject to certain conditions. The Amended ABL Facility has a five-year term expiring May 2027, expands available borrowing capacity associated with the Industrial Solutions rental mat fleet, replaces the LIBOR-based pricing grid with a Bloomberg Short-Term Bank Yield Index (“BSBY”) pricing grid, and includes a mechanism to incorporate a sustainability-linked pricing framework with the consent of the required lenders (as defined in the Amended ABL Facility).

As of December 31, 2022, our total borrowing availability under the Amended ABL Facility was $167.6 million, of which $80.3 million was drawn and $3.3 million was used for outstanding letters of credit, resulting in remaining availability of $84.0 million.

Borrowing availability under the Amended ABL Facility is calculated based on eligible U.S. accounts receivable, inventory and composite mats included in the rental fleet, net of reserves and subject to limits on certain of the assets included in the borrowing base calculation. To the extent pledged by the borrowers, the borrowing base calculation also includes the amount of eligible pledged cash. The administrative agent may establish reserves in accordance with the Amended ABL Facility, in part based on appraisals of the asset base, and other limits in its discretion, which could reduce the amounts otherwise available under the Amended ABL Facility.

Under the terms of the Amended ABL Facility, we may elect to borrow at a variable interest rate based on either, (1) the BSBY rate (subject to a floor of zero) or (2) the base rate (subject to a floor of zero), equal to the highest of (a) the federal funds rate plus 0.50%, (b) the prime rate of Bank of America, N.A., and (c) BSBY for a one-month interest period plus 1.00%, plus, in each case, an applicable margin per annum. The applicable margin ranges from 1.50% to 2.00% per annum for BSBY borrowings, and 0.50% to 1.00% per annum for base rate borrowings, based on the consolidated leverage ratio (as defined in the Amended ABL Facility) as of the last day of the most recent fiscal quarter. We are also required to pay a commitment fee equal to (i) 0.375% per annum at any time the average daily unused portion of the commitments is greater than 50% and (ii) 0.25% per annum at any time the average daily unused portion of the commitments is less than 50%.

As of December 31, 2022, the applicable margin for borrowings under the Amended ABL Facility was 1.75% with respect to BSBY borrowings and 0.75% with respect to base rate borrowings. As of December 31, 2022, the weighted average interest rate for the Amended ABL Facility was 5.9% and the applicable commitment fee on the unused portion of the Amended ABL Facility was 0.375% per annum.

The Amended ABL Facility is a senior secured obligation of the Company and certain of our U.S. subsidiaries constituting borrowers thereunder, secured by a first priority lien on substantially all of the personal property and certain real property of the borrowers, including a first priority lien on certain equity interests of direct or indirect domestic subsidiaries of the borrowers and certain equity interests issued by certain foreign subsidiaries of the borrowers.

The Amended ABL Facility contains customary representations, warranties and covenants that, among other things, and subject to certain specified circumstances and exceptions, restrict or limit the ability of the borrowers and certain of their

subsidiaries to incur indebtedness (including guarantees), grant liens, make investments, pay dividends or distributions with respect to capital stock and make other restricted payments, make prepayments on certain indebtedness, engage in mergers or other fundamental changes, dispose of property, and change the nature of their business.

The Amended ABL Facility requires compliance with the following financial covenants: (i) a minimum fixed charge coverage ratio of 1.00 to 1.00 for the most recently completed four fiscal quarters and (ii) while a leverage covenant trigger period (as defined in the Amended ABL Facility) is in effect, a maximum consolidated leverage ratio of 4.00 to 1.00 as of the last day of the most recently completed fiscal quarter.

The Amended ABL Facility includes customary events of default including non-payment of principal, interest or fees, violation of covenants, inaccuracy of representations or warranties, cross-default to other material indebtedness, bankruptcy and insolvency events, invalidity or impairment of security interests or invalidity of loan documents, certain ERISA events, unsatisfied or unstayed judgments and change of control.

Convertible Notes. In December 2016, we issued $100.0 million of unsecured convertible senior notes (“Convertible Notes”) which bore interest at a rate of 4.0% per year and matured in December 2021. A total of $38.6 million of our Convertible Notes were repaid at maturity. During 2021, we repurchased $28.3 million of our Convertible Notes in the open market for a total cost of $28.1 million and recognized a net loss of $1.0 million reflecting the difference in the amount paid and the net carrying value of the extinguished debt, including original issue discount and debt issuance costs. During 2020, we repurchased $33.1 million of our Convertible Notes in the open market for a total cost of $29.1 million and recognized a net gain of $0.4 million reflecting the difference in the amount paid and the net carrying value of the extinguished debt, including original issue discount and debt issuance costs.

Other Debt. In February 2021, a U.K. subsidiary entered a £6.0 million term loan facility that was scheduled to mature in February 2024. In April 2022, this facility was amended to increase the term loan to £7.0 million and establish a £2.0 million revolving credit facility. Both the amended term loan and revolving credit facility mature in April 2025 and bear interest at a rate of Sterling Overnight Index Average (“SONIA”) plus a margin of 3.25% per year. As of December 31, 2022, the interest rate for the U.K. facilities was 6.7%. The term loan is payable in quarterly installments of £350,000 plus interest beginning June 2022 and a £2.8 million payment due at maturity. We had $8.5 million outstanding under these arrangements at December 31, 2022.

In August 2021, we completed sale-leaseback transactions related to certain vehicles and other equipment for net proceeds of approximately $7.9 million. The transactions have been accounted for as financing arrangements as they did not qualify for sale accounting. As a result, the vehicles and other equipment continue to be reflected on our balance sheet in property, plant and equipment, net. The financing arrangements have a weighted average annual interest rate of 5.4% and are payable in monthly installments with varying maturities through October 2025. We had $3.4 million in financing obligations outstanding under these arrangements at December 31, 2022.

Certain of our foreign subsidiaries maintain local credit arrangements consisting primarily of lines of credit or overdraft facilities which are generally renewed on an annual basis. We utilize local financing arrangements in our foreign operations in order to provide short-term local liquidity needs. We had $14.3 million and $11.8 million outstanding under these arrangements at December 31, 2022 and 2021, respectively.

We incurred net interest expense of $7.0 million, $8.8 million and $11.0 million for the years ended December 31, 2022, 2021 and 2020, respectively. There was no capitalized interest for the years ended December 31, 2022, 2021 or 2020. As of December 31, 2022, we had scheduled repayments for financing arrangements of approximately $23 million in 2023, $4 million in 2024, $7 million in 2025, and $80 million in 2027.

Fair Value of Financial Instruments and Concentrations of Credit Risk

12 Months Ended

Dec. 31, 2022

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments and Concentrations of Credit Risk

Fair Value of Financial Instruments

Our financial instruments include cash and cash equivalents, receivables, payables, and debt. We believe the carrying values of these instruments approximated their fair values at December 31, 2022 and 2021.

Concentrations of Credit Risk

Financial instruments that potentially subject us to significant concentrations of credit risk primarily consist of cash and trade accounts receivable. At December 31, 2022, substantially all of our cash deposits were held by our international subsidiaries in accounts at numerous financial institutions across the various regions in which we operate. As part of our investment strategy, we perform periodic evaluations of the relative credit standing of these financial institutions.

Customer Revenue Concentration

We derive a significant portion of our revenues and profitability from companies in the energy industry, and more specifically, customers in the E&P and utility sectors. Our E&P customer base consists primarily of mid-sized and international oil companies as well as government-owned or government-controlled oil companies operating in the markets that we serve. Our utility customer base consists primarily of large regulated electrical utility providers, as well as power transmission service providers. For 2022, 2021 and 2020, revenues from our 20 largest customers represented approximately 38%, 39% and 49%, respectively, of our consolidated revenues. For 2022, 2021 and 2020, no single customer accounted for more than 10% of our consolidated revenues.

Receivables

Receivables consisted of the following at December 31:


(In thousands)	2022		2021
Trade receivables:
Gross trade receivables	$	227,762	$	185,065
Allowance for credit losses	(4,817)		(4,587)
Net trade receivables	222,945		180,478
Income tax receivables	2,697		4,167
Other receivables	16,605		9,651
Total receivables, net	$	242,247	$	194,296

The increase in trade receivables in 2022 was primarily attributable to the increase in revenues in the fourth quarter of 2022 compared to the fourth quarter of 2021, including trade amounts outstanding of $17.0 million at December 31, 2022 related to our divestitures described in Note 2.

Other receivables included $3.5 million and $5.7 million for value added, goods and service taxes related to foreign jurisdictions as of December 31, 2022 and 2021, respectively. Other receivables also included $10.8 million at December 31, 2022 related to our divestitures described in Note 2.

We adopted the new accounting guidance for credit losses as of January 1, 2020 (see Note 1 for additional information). To measure expected credit losses, we evaluate our receivables on a collective basis for assets that share similar risk characteristics. Our allowance for credit losses reflects losses that are expected over the contractual life of the asset, and takes into account historical loss experience, current and future economic conditions, and reasonable and supportable forecasts.

Changes in our allowance for credit losses were as follows:


(In thousands)	2022		2021		2020
Balance at beginning of year	$	4,587	$	5,024	$	6,007
Cumulative effect of accounting change	—		—		959
Credit loss expense	1,039		664		1,427
Write-offs, net of recoveries	(809)		(1,101)		(3,369)
Balance at end of year	$	4,817	$	4,587	$	5,024

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Leases

12 Months Ended

Dec. 31, 2022

Leases [Abstract]

Leases

We lease certain office space, warehouses, land, equipment, and an industrial facility. Our leases have remaining terms ranging from 1 to 9 years with various extension and termination options. We consider these options in determining the lease term used to establish our operating lease assets and liabilities. Lease agreements with lease and non-lease components are accounted for as a single lease component. Leases with an initial term of 12 months or less are not recorded in the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term.

Leases consisted of the following at December 31:

Total operating lease expenses were $27.3 million for 2022, of which $19.1 million related to short-term leases and $8.3 million related to leases recognized in the balance sheet. Total operating lease expenses were $24.4 million and $25.8 million for 2021 and 2020, respectively. Total operating lease expenses approximate cash paid during each period. Amortization and interest for finance leases are not material. Operating lease expenses and amortization of leased assets for finance leases are included in either cost of revenues or selling, general and administrative expenses. Interest for finance leases is included in interest expense, net.

The effective income tax rate is reconciled to the statutory federal income tax rate as follows:

Other items, net	415		(200)		218
Total provision (benefit) for income taxes	$	4,371	$	7,293	$	(11,883)

The provision for income taxes was $4.4 million for 2022, which includes an income tax benefit of $3.1 million related to the restructuring of certain subsidiary legal entities within Europe, as the undistributed earnings for an international subsidiary are no longer subject to certain taxes upon future distribution. The provision for income taxes in 2022 was unfavorably impacted as we are unable to recognize a tax benefit related to the $37.3 million of impairment charges. The provision for income taxes was $7.3 million for 2021, despite reporting a pretax loss for the period. In both years, income tax expense primarily reflects earnings from our international operations since we are unable to recognize the tax benefit from our U.S. losses as they may not be realized. The benefit for income taxes was $11.9 million for 2020 reflecting an effective tax benefit rate of 13%. This result primarily reflects the impact of the $11.7 million non-cash recognition of cumulative foreign currency translation losses related to the substantial liquidation of our subsidiary in Brazil and other nondeductible expenses, as well as the impact of the geographic composition of our pretax loss, where the tax benefit from losses in the U.S was partially offset by the tax expense related to earnings from our international operations.

The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted in March 2020 in the United States. The CARES Act contains several tax provisions, including additional carry back opportunities for net operating losses, temporary increases in the interest deductibility threshold, and the acceleration of refunds for any remaining alternative minimum tax (“AMT”) carryforwards. There was no material impact from the CARES Act in our provision for income taxes for 2020. In addition, we filed an amendment to our 2018 U.S. federal income tax return in the second quarter of 2020 and received a refund of $0.7 million for AMT carryforwards in July 2020.

The CARES Act also permitted most companies to defer paying their portion of certain applicable payroll taxes from the date the CARES Act was signed into law through December 31, 2020. The deferred amount was due and paid in two equal installments in December 2021 and 2022.

Temporary differences and carryforwards which give rise to deferred tax assets and liabilities consisted of the following at December 31:


(In thousands)	2022		2021
Deferred tax assets:
Net operating losses	$	35,430	$	38,746
Foreign tax credits	8,836		8,330

Noncurrent deferred tax liabilities	(8,121)		(11,819)
Net deferred tax liabilities	$	(5,846)	$	(9,503)

We have U.S. federal income tax net operating loss carryforwards (“NOLs”) of approximately $83.7 million available to reduce future U.S. taxable income, which do not expire. We also have state NOLs of approximately $217.8 million available to reduce future state taxable income, including approximately $158.3 million which do not expire and approximately $59.5 million which expire in varying amounts beginning in 2023 through 2042. Foreign NOLs of approximately $22.8 million are available to reduce future taxable income, some of which expire beginning in 2023. Effective January 1, 2022, certain research and development expenditures are now required under regulations enacted as part of the 2017 U.S. Tax Cuts and Jobs Act (“Tax Act”) to be capitalized and amortized over five years, resulting in a $4.3 million deferred tax asset at December 31, 2022.

The realization of our net deferred tax assets is dependent on our ability to generate taxable income in future periods. At December 31, 2022 and 2021, we have recorded a valuation allowance in the amount of $47.3 million and $38.4 million, respectively, primarily related to certain U.S. federal, state, and foreign NOL carryforwards, including Australia, as well as for certain foreign tax credits recognized related to the accounting for the impact of the Tax Act, which may not be realized.

We file income tax returns in the U.S. and several non-U.S. jurisdictions and are subject to examination in the various jurisdictions in which we file. We are no longer subject to income tax examinations for U.S. federal and substantially all state jurisdictions for years prior to 2018 and for substantially all foreign jurisdictions for years prior to 2008.

We are under examination by various tax authorities in countries where we operate, and certain foreign jurisdictions have challenged the amounts of taxes due for certain tax periods. These audits are in various stages of completion. We fully cooperate with all audits but defend existing positions vigorously. We evaluate the potential exposure associated with various filing positions and record a liability for uncertain tax positions as circumstances warrant. Although we believe all tax positions are reasonable and properly reported in accordance with applicable tax laws and regulations in effect during the periods involved, the final determination of tax audits and any related litigation could be materially different than that which is reflected in historical income tax provisions and accruals.

A reconciliation of the beginning and ending provision for uncertain tax positions is as follows:


(In thousands)	2022		2021		2020
Balance at January 1	$	485	$	213	$	291
Additions (reductions) for tax positions of prior years	(8)		(6)		(6)
Additions (reductions) for tax positions of current year	—		306		—
Reductions for settlements with tax authorities	(93)		—		—
Reductions for lapse of statute of limitations	(66)		(28)		(72)
Balance at December 31	$	318	$	485	$	213

Approximately $0.3 million of unrecognized tax benefits at December 31, 2022, if recognized, would favorably impact the effective tax rate.

We recognize accrued interest and penalties related to uncertain tax positions in operating expenses. The amount of interest and penalties was immaterial for all periods presented.

Basic	$	(0.22)	$	(0.28)	$	(0.89)
Diluted	$	(0.22)	$	(0.28)	$	(0.89)

We excluded the following weighted-average potential shares from the calculations of diluted net loss per share during the applicable periods because their inclusion would have been anti-dilutive:


	Year Ended December 31,
(In thousands)	2022	2021	2020
Stock options and restricted stock awards	5,545	5,754	5,238

For 2022, 2021 and 2020, we excluded all potentially dilutive stock options and restricted stock awards in calculating diluted earnings per share as the effect was anti-dilutive due to the net loss incurred for these periods. For 2021 and 2020, the Convertible Notes, which matured in December 2021, did not impact the calculation of diluted earnings per share due to the net loss incurred for those periods.

Stock-Based Compensation and Other Benefit Plans

12 Months Ended

Dec. 31, 2022

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation and Other Benefit Plans

The following describes stockholder approved plans utilized by us for the issuance of stock-based awards.

2014 Non-Employee Directors’ Restricted Stock Plan

In May 2014, our stockholders approved the 2014 Non-Employee Directors’ Restricted Stock Plan (“2014 Director Plan”) which authorizes grants of restricted stock to non-employee directors. Each restricted share granted to a non-employee director vests in full on the earlier of the day prior to the next annual meeting of stockholders following the grant date or the first anniversary of the grant. In May 2022, our stockholders approved an amendment to the 2014 Director Plan, increasing the number of shares authorized for issuance from 1,200,000 to 1,400,000 shares. At December 31, 2022, 86,188 shares remained available for award under the 2014 Director Plan. During 2022, non-employee directors received 260,339 shares of restricted stock at a weighted average grant-date fair value of $4.11 per share.

2015 Employee Equity Incentive Plan

In May 2015, our stockholders approved the 2015 Employee Equity Incentive Plan (“2015 Plan”) pursuant to which the Compensation Committee of our Board of Directors (“Compensation Committee”) may grant to key employees, including executive officers and other corporate and divisional employees, a variety of forms of equity-based compensation, including options to purchase shares of common stock, shares of restricted common stock, restricted stock units, stock appreciation rights, other stock-based awards, and performance-based awards. In May 2022, our stockholders approved an amendment to the 2015 Plan, increasing the number of shares authorized for issuance from 14,300,000 to 15,300,000 shares. At December 31, 2022, 1,767,893 shares remained available for award under the 2015 Plan.

In June 2017, our Board of Directors approved the Long-Term Cash Incentive Plan (“Cash Plan”), a sub-plan to the 2015 Plan, pursuant to which the Compensation Committee may grant time-based cash awards or performance-based cash awards to key employees, including executive officers and other corporate and divisional employees, to provide an opportunity

for employees to receive a cash payment upon either completion of a service period or achievement of predetermined performance criteria at the end of a performance period.

Activity under each of these programs is described below.

Stock Options

Stock options granted by the Compensation Committee are granted with a three-year vesting period and a term of ten years. There have been no options granted since 2016.

The following table summarizes activity for our outstanding stock options for the year ended December 31, 2022:


Stock Options	Shares	Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value (In thousands)
Outstanding at beginning of period	1,796,876	$	7.08
Granted	—	—
Exercised	—	—
Expired or canceled	(364,138)	5.71
Outstanding at end of period	1,432,738	$	7.39	2.40	$	—

Vested or expected to vest at end of period	1,432,738	$	7.39	2.40	$	—
Options exercisable at end of period	1,432,738	$	7.39	2.40	$	—

There were no stock options exercised and no compensation cost recognized for stock options during the years ended December 31, 2022, 2021, or 2020.

Restricted Stock Awards and Units

Time-vested restricted stock awards and restricted stock units are periodically granted to key employees, including grants for employment inducements, as well as to members of our Board of Directors. Employee awards provide for vesting periods ranging from three to four years. Non-employee director grants vest in full on the earlier of the day prior to the next annual meeting of stockholders following the grant date or the first anniversary of the grant. Upon vesting of these grants, shares are issued to award recipients.

The following tables summarize the activity for our outstanding time-vested restricted stock awards and restricted stock units for the year ended December 31, 2022:


Nonvested Restricted Stock Awards (Time-Vesting)	Shares	Weighted-Average Grant Date Fair Value
Nonvested at January 1, 2022	235,367	$	3.97

Total compensation cost recognized for restricted stock awards and restricted stock units was $6.7 million, $7.7 million and $6.3 million for the years ended December 31, 2022, 2021 and 2020, respectively. Total unrecognized compensation cost at December 31, 2022 related to restricted stock awards and restricted stock units was approximately $10.0 million which is expected to be recognized over the next 1.8 years. During the years ended December 31, 2022, 2021 and 2020, the total fair value of shares vested was $9.4 million, $5.3 million and $1.9 million, respectively. For the years ended December 31, 2022, 2021 and 2020, we recognized tax benefits resulting from the vesting of restricted stock awards and units of $1.8 million, $1.1 million and $0.4 million, respectively.

Cash-Based Awards

The Compensation Committee also approved the issuance of cash-based awards to certain executive officers during 2022, 2021 and 2020. The 2022 awards included a target amount of $2.8 million of performance-based cash awards. The 2021 awards included $1.4 million of time-based cash awards and a target amount of $3.0 million of performance-based cash awards. The 2020 awards included a target amount of $2.6 million of performance-based cash awards.

The performance-based cash awards are settled based on the relative ranking of our TSR as compared to the TSR of our designated peer group over a three-year period. The performance period began June 1, 2022 and ends May 31, 2025 for the 2022 awards, began May 2, 2021 and ends May 31, 2024 for the 2021 awards, and began May 2, 2020 and ends May 31, 2023 for the 2020 awards. The ending TSR price is equal to the average closing price of our shares over the last 30-calendar days of the performance period, and provide for a cash payout ranging from 0% to 200% of target for each eligible executive.

The performance-based cash awards are accrued as a liability award over the performance period based on the estimated fair value. The fair value of the performance-based cash awards is remeasured each period using a Monte Carlo valuation model with changes in fair value recognized in the consolidated statement of operations. As of December 31, 2022 and 2021, the total liability for cash-based awards was $6.5 million and $5.7 million, respectively.

Defined Contribution Plan

Substantially all of our U.S. employees are covered by a defined contribution plan (“401(k) Plan”). Employees may voluntarily contribute up to 50% of compensation, as defined in the 401(k) Plan. Participants’ contributions, up to 3% of compensation, are matched 100% by us, and the participants’ contributions, from 3% to 6% of compensation, are matched 50% by us. Effective January 1, 2023, Participant’s contributions up to 4% are matched 100% by us with contributions from 4% to 6% being matched 50%. In connection with the cost reduction programs implemented in early 2020, we temporarily eliminated our 401(k) matching contribution beginning in April 2020. Beginning in the second quarter of 2021, we reinstituted the matching contribution for our U.S. defined contribution plan. Under the 401(k) Plan, our cash contributions were $2.5 million, $2.2 million and $1.2 million for 2022, 2021 and 2020, respectively.

Segment Reporting [Abstract]

Segment and Related Information

We currently operate our business through two reportable segments: Fluids Systems and Industrial Solutions. In addition, we had a third reportable segment, Industrial Blending, which was exited in 2022. Prior to 2022, we aggregated our now exited Industrial Blending business and reported it within Industrial Solutions. We have reflected these three reportable segments for all periods presented in this Annual Report on Form 10-K. All intercompany revenues and related profits have been eliminated.

•Fluids Systems — Our Fluids Systems segment provides customized drilling, completion, and stimulation fluids products and related technical services to customers for oil, natural gas, and geothermal projects primarily in North America and EMEA, as well as certain countries in Asia Pacific and Latin America. In the fourth quarter of 2022, we exited two of our Fluids Systems business units, including our U.S.-based mineral grinding business as well as our Gulf of Mexico fluids operations (see Note 2 for additional information).

•Industrial Solutions — Our Industrial Solutions segment provides temporary worksite access solutions, including the rental of our recyclable composite matting systems, along with related site construction and services to customers in various markets including power transmission, E&P, pipeline, renewable energy, petrochemical, construction and other industries, primarily in the United States and Europe. We also manufacture and sell our recyclable composite mats to customers around the world, with power transmission being the primary end-market.

•Industrial Blending — Our Industrial Blending segment began operations in 2020 and supported industrial end-markets, including the production of disinfectants and industrial cleaning products. We completed the wind down of the Industrial Blending business in the first quarter of 2022, and we completed the sale of the industrial blending and warehouse facility and related equipment located in Conroe, Texas in the fourth quarter of 2022 (see Note 2 for additional information).

Summarized financial information for our reportable segments is shown in the following tables:

The increase in Corporate office segment assets primarily relates to the transition in 2022 of our Katy, Texas technology center from the Fluids Systems segment to a multi-purpose facility housing both business headquarters and support personnel, as well as administrative offices for two third-party lessees. The decrease in Fluids Systems segment assets includes the impact of the Excalibar divestiture (see Note 2) and the transfer of the Katy technology center to the Corporate office, as described above, partially offset by an increase in working capital.

Operating results for the Fluids Systems segment include the following charges. See Note 2 for additional information regarding the 2022 charges.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the ordinary course of conducting our business, we become involved in litigation and other claims from private party actions, as well as judicial and administrative proceedings involving governmental authorities at the federal, state, and local levels. While the outcome of litigation or other proceedings against us cannot be predicted with certainty, management does not expect that any loss resulting from such litigation or other proceedings, in excess of any amounts accrued or covered by insurance, will have a material adverse impact on our consolidated financial statements. Other We do not have any special purpose entities. At December 31, 2022, we had $42.3 million in outstanding letters of credit, performance bonds, and other guarantees for which certain of the letters of credit are collateralized by $1.9 million in restricted cash. We also enter into normal short-term operating leases for office and warehouse space, as well as certain operating equipment. None of these off-balance sheet arrangements either had, or is expected to have, a material effect on our financial statements. We are self-insured for health claims, subject to certain “stop loss” insurance policies. Claims in excess of $250,000 per incident are insured by third-party insurers. Based on historical experience, we had accrued liabilities of $0.7 million for unpaid claims incurred at both December 31, 2022 and 2021. Substantially all of these estimated claims are expected to be paid within six months of their occurrence. In addition, we are self-insured for certain workers’ compensation, auto, and general liability claims up to a certain policy limit. Claims in excess of $750,000 are insured by third-party reinsurers. Based on historical experience, we had accrued liabilities of $3.1 million and $2.5 million for the uninsured portion of claims at December 31, 2022 and 2021, respectively. We also maintain accrued liabilities for asset retirement obligations, which represent obligations associated with the retirement of tangible long-lived assets that result from the normal operation of the long-lived asset. Our asset retirement obligations primarily relate to required expenditures associated with owned and leased facilities. Upon settlement of the liability, a gain or loss for any difference between the settlement amount and the liability recorded is recognized. We had accrued asset retirement obligations of $1.2 million and $1.1 million at December 31, 2022 and 2021, respectively.
