NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    SUMMARY OF MAJOR ACCOUNTING POLICIES

Basis of Presentation. Oceaneering International, Inc. (“Oceaneering,” “we” “our” or “us”) has prepared these unaudited consolidated financial statements pursuant to instructions for quarterly reports on Form 10-Q, which we are required to file with the United States Securities and Exchange Commission (the “SEC”). These financial statements do not include all information and footnotes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). These financial statements reflect all adjustments that we believe are necessary to present fairly our financial position as of September 30, 2023, and our results of operations and cash flows for the periods presented. Except as otherwise disclosed herein, all such adjustments are of a normal and recurring nature. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in our annual report on Form 10-K for the year ended December 31, 2022. The results for interim periods are not necessarily indicative of annual results.

Principles of Consolidation. The consolidated financial statements include the accounts of Oceaneering and our 50% or more owned and controlled subsidiaries. We also consolidate entities that are determined to be variable interest entities if we determine that we are the primary beneficiary; otherwise, we account for those entities using the equity method of accounting. We use the equity method to account for our investments in unconsolidated affiliated companies of which we own an equity interest of between 20% and 50% and as to which we have significant influence, but not control, over operations. We use the cost method for all other long-term investments. Investments in entities that we do not consolidate are reflected on our balance sheet in other noncurrent assets. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires that our management make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates.

Reclassifications. Certain amounts from prior periods have been reclassified to conform with the current period presentation.

Cash and Cash Equivalents. Cash and cash equivalents include demand deposits and highly liquid investments with original maturities of three months or less from the date of investment.

Allowances for Credit Loss—Financial Assets Measured at Amortized Costs. We identify our allowance for credit losses based on future expected losses when accounts receivable, contract assets or held-to-maturity loan receivables are created rather than when losses are probable.

We use the loss-rate method in developing the allowance for credit losses, which involves identifying pools of assets with similar risk characteristics, reviewing historical losses within the last three years and consideration of reasonable supportable forecasts of economic indicators. Changes in estimates, developing trends and other new information could have material effects on future evaluations.

We monitor the credit quality of our accounts receivable and other financing receivable amounts by frequent customer interaction, following economic and industry trends and reviewing specific customer data. Our other receivable amounts include contract assets and held-to-maturity loans receivable, which we consider to have a low risk of loss.

We consider macroeconomic conditions when assessing our credit risk exposure, including any impacts from the conflicts in Russia and Ukraine and in the Middle East and volatility in the financial services industry and the oil and natural gas markets, and the effects thereof on our customers and various counterparties. We have determined the impacts to our credit loss expenses are de minimis for the three- and nine-month periods ended September 30, 2023 and 2022.

As of September 30, 2023, our allowance for credit losses was $2.1 million for accounts receivable and $0.6 million for other receivables. As of December 31, 2022, our allowance for credit losses was $2.0 million for accounts receivable and $0.3 million for other receivables. Our allowance for credit losses increased in the nine months

ended September 30, 2023, as compared to the same period in the prior year, primarily due to corresponding increases in revenue and accounts receivable.

Financial assets are written off when deemed uncollectible and there is no reasonable expectation of recovering the contractual cash flows. During the three- and nine-month periods ended September 30, 2023, we did not write off any financial assets. In the three months ended September 30, 2023, we received cash proceeds of $1.8 million as partial recovery of a previously written off financial asset.

Accounts receivable are considered to be past due after the end of the contractual terms agreed to with the customer. There were no material past due amounts that we consider uncollectible for our financial assets as of September 30, 2023. We generally do not require collateral from our customers.

Inventory. Inventory is valued at the lower of cost or net realizable value. We determine cost using the weighted-average method. We periodically review the value of items in inventory and record write-downs or write-offs of inventory based on our assessment of market conditions. Write-downs and write-offs are charged to cost of services and products. We did not record any write-downs or write-offs of inventory in the three- and nine-month periods ended September 30, 2023 and 2022.

Property and Equipment, Long-Lived Intangible Assets and Right-of-Use Operating Lease Assets. We provide for depreciation of property and equipment on the straight-line method over estimated useful lives. We charge the costs of repair and maintenance of property and equipment to operations as incurred, and we capitalize the costs of improvements that extend asset lives or functionality. Upon the disposition of property and equipment, the related cost and accumulated depreciation accounts are relieved, and any resulting gain or loss is recognized as income.

We capitalize interest on assets where the construction period is anticipated to be more than three months. We did not capitalize interest in the three- and nine-month periods ended September 30, 2023 and 2022. We do not allocate general administrative costs to capital projects.

Long-lived intangible assets, primarily acquired in connection with business combinations, include trade names, intellectual property and customer relationships and are being amortized over their respective estimated useful lives.

Our management periodically, and upon the occurrence of a triggering event, reviews the realizability of our property and equipment, long-lived intangible assets and right-of-use operating lease assets to determine whether any events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable. For long-lived assets to be held and used, we base our evaluation on impairment indicators such as the nature of the assets, the future economic benefits of the assets, any historical or future profitability measurements and other external market conditions or factors that may be present. If such impairment indicators are present or other factors exist that indicate that the carrying amount of an asset may not be recoverable, we determine whether an impairment has occurred through the use of an undiscounted cash flows analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, we recognize a loss for the difference between the carrying amount and the fair value of the asset. We did not identify indicators of impairment for property and equipment, long-lived intangible assets or right-of-use operating lease assets for the three- and nine-month periods ended September 30, 2023 and 2022.

For assets held for sale or disposal, the fair value of the asset is measured using fair market value less estimated costs to sell. Assets are classified as held for sale when we have a plan for disposal of certain assets and those assets meet the held for sale criteria.

For additional information regarding right-of-use operating lease assets, see “Leases” below.

Goodwill. Our goodwill is evaluated for impairment annually and whenever we identify certain triggering events or circumstances that would more likely than not reduce the fair value of a reporting unit below its carrying amount.

In our annual evaluation of goodwill, we perform a qualitative or quantitative impairment test. Under the qualitative approach, if we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we are required to perform the quantitative analysis to determine the fair value for the reporting unit. We then compare the fair value of the reporting unit with its carrying amount and recognize an impairment loss for the amount by which the carrying amount exceeds the fair value of the reporting unit. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. We also consider income tax effects from any

tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. We did not identify indicators of impairment for goodwill for the three- and nine-month periods ended September 30, 2023 and 2022.

Revenue Recognition. All our revenue is realized through contracts with customers. We recognize our revenue according to the contract type. On a daily basis, we recognize service revenue over time for contracts that provide for specific time, material and equipment charges, which we bill periodically, ranging from weekly to monthly. We use the input method to recognize revenue, because each day of service provided represents value to the customer. The performance obligations in these contracts are satisfied, and revenue is recognized, as the work is performed. When appropriate, we apply the practical expedient to recognize revenue for the amount invoiced when the invoice corresponds directly to the value of our performance to date.

We account for significant fixed-price contracts, mainly relating to our Manufactured Products segment, and to a lesser extent in our Offshore Projects Group (“OPG”) and Aerospace and Defense Technologies (“ADTech”) segments, by recognizing revenue over time using the cost-to-cost input method. A performance obligation is satisfied as we create a product on behalf of the customer over the life of the contract. The remainder of our revenue is recognized at the point in time when control transfers to the customer, thus satisfying the performance obligation.

We have elected to recognize the cost for freight and shipping as an expense when incurred. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, and that are collected by us from customers, are excluded from revenue.

In our service-based business lines, we principally charge on a dayrate basis for services provided. In our product-based business lines, predominantly in our Manufactured Products segment, we recognize revenue and profit using the percentage-of-completion method and exclude uninstalled materials and significant inefficiencies from the measure of progress.

We apply judgment in the determination and allocation of transaction price to performance obligations, and the subsequent recognition of revenue, based on the facts and circumstances of each contract. We routinely review estimates related to our contracts and, when required, reflect revisions to profitability in earnings immediately. If an element of variable consideration has the potential for a significant future reversal of revenue, we will constrain that variable consideration to a level intended to remove the potential future reversal. If a current estimate of total contract cost indicates an ultimate loss on a contract, we recognize the projected loss in full when we determine it. During the three- and nine-month periods ended September 30, 2023, we recognized projected losses of $1.8 million and $4.7 million, respectively, for entertainment business contracts in our Manufactured Products segment. During the three- and nine-month periods ended September 30, 2022, we recognized projected losses of $1.5 million and $4.0 million, respectively, for contracts in our Manufactured Products segment. There could be significant adjustments to overall contract costs in the future, due to changes in facts and circumstances.

In general, our payment terms consist of those services billed regularly as provided and those products delivered at a point in time, which are invoiced after the performance obligation is satisfied. Our product and service contracts with milestone payments due at agreed progress points during the contract are invoiced when those milestones are reached, which may differ from the timing of revenue recognition. Our payment terms generally do not provide financing of contracts to customers, nor do we receive financing from customers as a result of these terms.

See Note 3—“Revenue” for more information on our revenue from contracts with customers.

Leases. We determine whether a contract is or contains a lease at inception, whether as a lessee or a lessor. We take into consideration the elements of an identified asset, right to control and the receipt of economic benefit in making those determinations.

As a lessor, we lease certain types of equipment along with the provision of services and utilize the expedient allowing us to combine the lease and non-lease components into a combined component that is accounted for (1) under “Leases” (“ASC 842”), when the lease component is predominant, and (2) under the accounting standard “Revenue from Contracts with Customers” (“ASC 606”), when the service component is predominant. In general, when we have a service component, it is typically the predominant element and leads to accounting under ASC 606.

As a lessor, we lease certain types of equipment, often providing services at the same time. These leases can be priced on a dayrate or lump-sum basis for periods ranging from a few days to multi-year contracts. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our

customer's discretion. These leases generally do not contain options to purchase, material restrictions or covenants that impact our accounting for leases.

As a lessee, we lease land, buildings, vessels and equipment for the operation of our business and to support some of our service line revenue streams. These generally carry lease terms that range from days for operational and support equipment to 15 years for land and buildings. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our discretion. When the exercise of those options is reasonably certain, we include them in the lease assessment. Our leases do not contain material restrictions or covenants that impact our accounting for them, nor do we provide residual value guarantees.

As a lessee, we utilize the practical expedients to not recognize leases with an initial lease term of 12 months or less on the balance sheet and to combine lease and non-lease components together and account for the combined component as a lease for all asset classes, except real estate.

Right-of-use operating lease assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement or modification date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate, based on the information available at commencement or modification date in determining the present value of future payments. In determining the incremental borrowing rate, we considered our external credit ratings, bond yields for us and our identified peers, the risk-free rate in geographic regions where we operate, and the impact associated with providing collateral over a similar term as the lease for an amount equal to the future lease payments. Our right-of-use operating lease assets also include any lease prepayments made and exclude lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease. These options are included in the lease term when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

Foreign Currency Translation. The functional currency for most of our foreign subsidiaries is the applicable local currency. Results of operations for foreign subsidiaries with functional currencies other than the U.S. dollar are translated into U.S. dollars using average exchange rates during the period. Assets and liabilities of these foreign subsidiaries are translated into U.S. dollars using the exchange rates in effect as of the balance sheet date, and the resulting translation adjustments are recognized, net of tax, in accumulated other comprehensive income (loss) as a component of shareholders' equity. All foreign currency transaction gains and losses are recognized currently in the Consolidated Statements of Operations. We recorded $0.9 million and $(3.6) million of foreign currency transaction gains (losses) in the three- and nine-month periods ended September 30, 2023, respectively. We recorded $(1.1) million and $0.2 million of foreign currency transaction gains (losses) in the three- and nine-month periods ended September 30, 2022, respectively. Those amounts are included as a component of other income (expense), net in our Consolidated Statement of Operations.

2.    ACCOUNTING STANDARDS UPDATE

There are no new accounting standards issued in the nine months ended September 30, 2023, that would have a material impact on our consolidated financial statements.

Contract Balances

Our contracts with milestone payments have, in the aggregate, a significant impact on the contract asset and the contract liability balances. Milestones are contractually agreed with customers and relate to significant events across the contract lives. Some milestones are achieved before revenue is recognized, resulting in a contract liability, while other milestones are achieved after revenue is recognized, resulting in a contract asset.

Performance Obligations

As of September 30, 2023, the aggregate amount of the transaction price allocated to remaining performance obligations that were unsatisfied (or partially unsatisfied) was $449 million. In arriving at this value, we have used two expedients available to us and are not disclosing amounts in relation to performance obligations: (1) that are part of contracts with an original expected duration of one year or less; or (2) on contracts where we recognize revenue in line with the billing. Of this amount, we expect to recognize revenue of $324 million over the next 12 months, $124 million within the next 24 months and we expect to recognize substantially all of the remaining balance of $2.2 million within the next 36 months.

In our Manufactured Products and ADTech segments, we have long-term contracts that extend beyond one year, and these make up the majority of the performance obligations balance reported as of September 30, 2023. We also have shorter-term product contracts with an expected original duration of one year or less that have been excluded.

Where appropriate, we have made estimates within the transaction price of elements of variable consideration within the contracts and constrained those amounts to a level where we consider it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The amount of revenue recognized in the three- and nine-month periods ended September 30, 2023 and 2022, that was associated with performance obligations completed or partially completed in prior periods was not significant.

As of September 30, 2023, there were no significant outstanding liability balances for refunds or returns due to the nature of our contracts and the services and products we provide. Our warranties are limited to assurance warranties that are of a standard length and are not considered to be material rights. The majority of our contracts consist of a single performance obligation. When there are multiple obligations, we look for observable evidence of stand-alone selling prices on which to base the allocation. This involves judgment as to the appropriateness of the observable evidence relating to the facts and circumstances of the contract. If we do not have observable evidence, we estimate stand-alone selling prices by taking a cost-plus-margin approach, using typical margins from the type of product or service, customer and regional geography involved.

Costs to Obtain or Fulfill a Contract

In line with the available practical expedient, we capitalize incremental costs to obtain a contract that would not have been incurred if the contract had not been obtained when those amounts are significant and the contract is expected at inception to exceed one year in duration. Our costs to obtain a contract primarily consist of bid and proposal costs, which are generally expensed in the period when incurred. There were no balances or amortization of costs to obtain a contract in the current reporting periods.

Costs to fulfill a contract primarily consist of certain mobilization costs incurred to provide services or products to our customers. These costs are deferred and amortized over the period of contract performance. The closing balance of costs to fulfill a contract was $8.1 million and $10 million as of September 30, 2023 and December 31, 2022, respectively. For the three- and nine-month periods ended September 30, 2023, we recorded amortization expense

12

Table of Contents

of $1.2 million and $4.0 million, respectively. For the three- and nine-month periods ended September 30, 2022, we recorded amortization expense of $1.2 million and $4.2 million, respectively. No impairment costs were recognized.

4.    INCOME TAXES

Our tax provision is based on (1) our earnings for the period and other factors affecting the tax provision and (2) the operations of foreign branches and subsidiaries that are subject to local income and withholding taxes. Factors that affect our tax rate include our profitability levels in general and the geographical mix of our results. The effective tax rate for the three- and nine-month periods ended September 30, 2023 and 2022, was different than the U.S. federal statutory rate of 21%, primarily due to the geographical mix of revenue and earnings, changes in valuation allowances and uncertain tax positions, and other discrete items. We do not believe a comparison of the effective tax rate for the three- and nine-month periods ended September 30, 2023 and 2022, is meaningful. We continue to make an assertion to indefinitely reinvest the unrepatriated earnings of any foreign subsidiary that would incur material tax consequences upon the distribution of such earnings.

During the nine-month period ended September 30, 2023, we received refunds of $23 million, including interest of $1.7 million, which was recorded as a tax benefit under the U.S. Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The outstanding refund of $20 million was classified as other noncurrent assets on our consolidated balance sheet as of December 31, 2022.

We conduct our international operations in jurisdictions that have varying laws and regulations regarding income and other taxes, some of which are subject to different interpretations. We recognize benefit for an uncertain tax position if it is more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the uncertain tax position is then measured and recognized at the largest amount that we believe is greater than 50% likely of being realized upon ultimate settlement.

We have accrued a net total of $29 million and $11 million in other long-term liabilities on our consolidated balance sheet for worldwide unrecognized tax liabilities as of September 30, 2023 and December 31, 2022, respectively. We account for any applicable interest and penalties related to uncertain tax positions as a component of our provision for income taxes in our consolidated financial statements. Changes in our management's judgment related to those liabilities would affect our effective income tax rate in the periods of change.

Our tax returns are subject to audit by taxing authorities in multiple jurisdictions. These audits often take years to complete and settle. The following table lists the earliest tax years open to examination by tax authorities where we have significant operations:

Jurisdiction	Periods
United States	2014
United Kingdom	2020
Norway	2018
Angola	2015
Brazil	2018
Australia	2018

We have ongoing tax audits and judicial tax appeals in various jurisdictions. The outcome of these audits and judicial tax appeals may have an impact on uncertain tax positions for income tax returns subsequently filed in those jurisdictions.

In November 2014, we completed the public offering of $500 million aggregate principal amount of 4.650% Senior Notes due 2024 (the “2024 Senior Notes”). We pay interest on the 2024 Senior Notes on May 15 and November 15 of each year. The 2024 Senior Notes are scheduled to mature on November 15, 2024. In the year ended December 31, 2021, we repurchased $100 million in aggregate principal amount of the 2024 Senior Notes in open-market transactions. On October 2, 2023, we repurchased $312 million principal amount of the 2024 Senior Notes at par plus accrued and unpaid interest of $5.5 million for approximately $318 million in the Tender Offer (as defined herein). On October 2, 2023, we delivered a notice to the holders of the 2024 Senior Notes that we have elected to redeem all of the remaining $88 million principal amount outstanding of the 2024 Senior Notes on November 2, 2023 (the “Redemption Date”), pursuant to our optional redemption right under the indenture governing the 2024 Senior Notes. The redemption price will be equal to 100% of the principal amount of the 2024 Senior Notes plus accrued and unpaid interest up to but not including the Redemption Date plus a “make-whole premium.” See Note 10—“Subsequent Events” for additional information on the Tender Offer (as defined herein) and the redemption of the 2024 Senior Notes.

Table of Contents

In February 2018, we completed the public offering of $300 million aggregate principal amount of 6.000% Senior Notes due 2028 (the “Existing 2028 Senior Notes”). We pay interest on the Existing 2028 Senior Notes on February 1 and August 1 of each year. The Existing 2028 Senior Notes are scheduled to mature on February 1, 2028. We used the net proceeds from the Existing 2028 Senior Notes to repay indebtedness.

We may redeem some or all of the Existing 2028 Senior Notes at specified redemption prices. In the three- and nine-month periods ended September 30, 2023 and 2022, we did not repurchase any of the 2024 Senior Notes or the Existing 2028 Senior Notes.

On October 2, 2023, we completed a private placement of $200 million aggregate principal amount of additional 2028 Senior Notes (the “New 2028 Senior Notes” and, together with the Existing 2028 Senior Notes, the “2028 Senior Notes”) to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act. The New 2028 Senior Notes constitute an additional issuance of the Existing 2028 Senior Notes and form a single series with such notes. We will pay interest on the New 2028 Senior Notes on February 1 and August 1 of each year, commencing on February 1, 2024. The New 2028 Senior Notes are scheduled to mature on February 1, 2028. We may redeem some or all of the New 2028 Senior Notes at specified redemption prices. We received proceeds from the offering of the New 2028 Senior Notes of approximately $180 million, after initial purchasers’ discounts. We used the net proceeds from the New 2028 Senior Notes, together with cash on hand, to fund the Tender Offer (as defined herein). As a result of these transactions, we reclassified approximately $132 million from long-term debt to the current portion of long-term debt as of September 30, 2023. The current portion of long-term debt represents the amount of the 2024 Senior Notes repurchased subsequent to period end utilizing cash on hand as of September 30, 2023, with the remainder repurchased using proceeds from the subsequent issuance of the New 2028 Senior Notes.

On April 8, 2022, we entered into a senior secured revolving credit agreement with a group of banks (as amended by an Agreement and Amendment No. 1 to Credit Agreement, dated September 20, 2023, the “Revolving Credit Agreement”). The commitments under the Revolving Credit Agreement are scheduled to mature on April 8, 2027, or 91 days prior to the maturity date of the 2024 Senior Notes if either we have not prepaid such notes by such date or our Liquidity (as defined in the Revolving Credit Agreement) is less than $175 million on such date. The Revolving Credit Agreement includes a $215 million revolving credit facility (the “Revolving Credit Facility”) with a $100 million sublimit for the issuance of letters of credit. Our obligations under the Revolving Credit Agreement are guaranteed by certain of our wholly owned subsidiaries and are secured by first priority liens on certain of our assets and those of the guarantors, including, among other things, intellectual property, inventory, accounts receivable, equipment and equity interests in subsidiaries. As of September 30, 2023, we had no borrowings outstanding under the Revolving Credit Facility and no letters of credit outstanding under the Revolving Credit Agreement.

We may borrow under the Revolving Credit Facility at either (1) a base rate, determined as the greatest of (A) the prime rate of Wells Fargo Bank, National Association, (B) the federal funds effective rate plus 1⁄2 of 1% and (C) Adjusted Term SOFR (as defined in the Revolving Credit Agreement) for a one-month tenor plus 1%, in each case plus the applicable margin, which varies from 1.25% to 2.25% depending on our Consolidated Net Leverage Ratio (as defined in the Revolving Credit Agreement), or (2) Adjusted Term SOFR plus the applicable margin, which varies from 2.25% to 3.25% depending on our Consolidated Net Leverage Ratio. We will also pay a facility fee based on the amount of the underlying commitment that is being utilized, which fee varies from 0.300% to 0.375%, with the higher rate owed when we use the Revolving Credit Facility less.

The Revolving Credit Agreement includes financial covenants that are tested on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter. The maximum permitted Consolidated Net Leverage Ratio is initially 4.00 to 1.00 and will decrease to 3.25 to 1.00 during the term of the Revolving Credit Facility. As of September 30, 2023, the maximum permitted Consolidated Net Leverage Ratio was 3.50 to 1.00. The minimum Consolidated Interest Coverage Ratio (as defined in the Revolving Credit Agreement) is 3.00 to 1.00 throughout the term of the Revolving Credit Facility. Availability under the Revolving Credit Facility may be limited by these financial covenants and the requirement that any borrowing under the Revolving Credit Facility not require the granting of any liens to secure any senior notes issued by us (“Senior Notes”). The indentures governing the 2024 Senior Notes and the 2028 Senior Notes generally limit our ability to incur secured debt for borrowed money (such as borrowings under the Revolving Credit Facility) to 15% of our Consolidated Net Tangible Assets (as defined in such indentures). As of September 30, 2023, the full $215 million was available to borrow under the Revolving Credit Facility. In addition, the Revolving Credit Agreement contains various covenants that we believe are customary for agreements of this nature, including, but not limited to, restrictions on our ability and the ability of

15

each of our subsidiaries to incur debt, grant liens, make certain investments, make distributions, merge or consolidate, sell assets and enter into certain restrictive agreements. As of September 30, 2023, we were in compliance with all the covenants set forth in the Revolving Credit Agreement.

We had two interest rate swaps in place relating to a total of $200 million of the 2024 Senior Notes for the period to November 2024. The agreements swapped the fixed interest rate of 4.65% on $100 million of the 2024 Senior Notes to the floating rate of one-month London Interbank Offered Rate (“LIBOR”) plus 2.426% and on another $100 million to one-month LIBOR plus 2.823%. In March 2020, we settled both interest rate swaps with the counterparty for cash proceeds of $13 million. The settlement resulted in a $13 million increase to our long-term debt balance that is being amortized to interest expense through the maturity date for the 2024 Senior Notes using the effective interest method. As a result, we amortized $0.6 million and $1.7 million to interest expense for the three- and nine-month periods ended September 30, 2023, respectively and $0.5 million and $1.6 million to interest expense for the three- and nine-month periods ended September 30, 2022, respectively.

We incurred $6.9 million and $4.2 million of issuance costs related to the 2024 Senior Notes and the Existing 2028 Senior Notes, respectively, and $4.0 million of loan costs related to the Revolving Credit Agreement. These costs, net of accumulated amortization, are included as a reduction of long-term debt on our Consolidated Balance Sheets, as they pertain to the Senior Notes, and in other noncurrent assets, as they pertain to the Revolving Credit Agreement. We are amortizing these costs to interest expense through the respective maturity dates for the Senior Notes and the Revolving Credit Agreement using the straight-line method, which approximates the effective interest rate method. As a result, we amortized $0.5 million and $1.6 million to interest expense for the three- and nine-month periods ended September 30, 2023, respectively, and $0.6 million and $1.6 million to interest expense for the three- and nine-month periods ended September 30, 2022, respectively.

7.    COMMITMENTS AND CONTINGENCIES

Litigation. In the ordinary course of business, we are, from time to time, involved in litigation or subject to disputes, governmental investigations or claims related to our business activities, including, among other things:

•performance- or warranty-related matters under our customer and supplier contracts and other business arrangements; and

•workers’ compensation claims, Jones Act claims, occupational hazard claims, premises liability claims and other claims.

Although we cannot predict the ultimate outcome of these matters, we believe that our ultimate liability, if any, that may result from these other actions and claims will not have a material adverse effect on our consolidated financial condition, results of operations or cash flows. However, because of the inherent uncertainty of litigation and other dispute resolution proceedings and, in some cases, the availability and amount of potentially available insurance, we can provide no assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material effect on our consolidated financial condition, results of operations or cash flows for the fiscal period in which that resolution occurs.

Financial Instruments and Risk Concentration. In the normal course of business, we manage risks associated with foreign exchange rates and interest rates through a variety of strategies, including the use of hedging transactions. As a matter of policy, we do not use derivative instruments unless we have an underlying exposure. Other financial instruments that potentially subject us to concentrations of credit risk are principally cash and cash equivalents and accounts receivable.

The carrying values of cash and cash equivalents approximate their fair values due to the short-term maturity of the underlying instruments. Accounts receivable are generated from a broad group of customers, primarily from the energy industry and the U.S. government, which are major sources of our revenue. Due to their short-term nature, carrying values of our accounts receivable and accounts payable approximate fair market values.

We estimated the aggregate fair market value of the Senior Notes to be $678 million as of September 30, 2023, based on quoted prices. Since the market for the Senior Notes is not an active market, the fair value of the Senior Notes is classified within Level 2 in the fair value hierarchy under U.S. GAAP (inputs other than quoted prices in active markets for similar assets and liabilities that are observable or can be corroborated by observable market data for substantially the full terms for the assets or liabilities).

Foreign currency gains (losses) related to the Angolan kwanza of $0.8 million and $(5.2) million in the three- and nine-month periods ended September 30, 2023, respectively, and $(1.4) million and $0.7 million in the three- and nine-month periods ended September 30, 2022, respectively, were primarily related to increasing (declining) exchange rates for the Angolan kwanza relative to the U.S. dollar. We recorded foreign currency transaction gains (losses) related to the Angolan kwanza as a component of other income (expense), net in our Consolidated Statements of Operations.

Any conversion of cash balances from kwanza to U.S. dollars is controlled by the central bank in Angola. As of September 30, 2023 and December 31, 2022, we had the equivalent of approximately $13 million and $5.6 million, respectively, of kwanza cash balances in Angola reflected on our Consolidated Balance Sheets.

To mitigate our currency exposure risk in Angola, we used kwanza to purchase equivalent Angolan central bank (Banco Nacional de Angola) bonds. The bonds were denominated as U.S. dollar equivalents, so that, upon payment of semi-annual interest and principal upon maturity, payment was made in kwanza, equivalent to the respective U.S. dollars at the then-current exchange rate. Our remaining Angolan bonds matured on September 1, 2023, and we received cash proceeds of $6.2 million.

As of December 31, 2022, we had $6.2 million of U.S. dollar equivalent Angolan bonds. These bonds were classified as available-for-sale securities; accordingly, they were recorded at fair market value in other current assets in our Consolidated Balance Sheets as of December 31, 2022. We did not sell any of our Angolan bonds in the three- and nine-month periods ended September 30, 2022. We estimated the fair market value of the Angolan bonds to be $6.4 million as of December 31, 2022, using quoted market prices. Since the market for the Angolan bonds was not an active market, the fair value of the Angolan bonds was classified within Level 2 in the fair value hierarchy under U.S. GAAP. As of December 31, 2022, we had $0.1 million in unrealized loss, net of tax, related to these bonds as a component of accumulated other comprehensive loss in our Consolidated Balance Sheets.

In the three-month period ended June 30, 2021, we were notified by a customer in our Manufactured Products segment that it was suspending a contract that was substantially complete. Specific to this contract, we billed and received $19 million of accounts receivable during the first nine months of 2023. As of September 30, 2023, we had outstanding contract assets of approximately $20 million for the contract and $3.6 million in contract liabilities. As of December 31, 2022, we had outstanding contract assets of approximately $19 million for the contract and contract liabilities of $0.6 million prepaid for storage of components. We are in discussions with the customer concerning the timing of remaining payments. We continue to believe that we will realize these contract assets at their book values, although we can provide no assurance as to the timing of receipt of the remaining payments.

8.    EARNINGS (LOSS) PER SHARE, SHARE-BASED COMPENSATION AND SHARE REPURCHASE PLAN

Earnings (Loss) per Share. For each period presented, the only difference between our calculated weighted-average basic and diluted number of shares outstanding is the effect of outstanding restricted stock units. In periods where we have a net loss, the effect of our outstanding restricted stock units is anti-dilutive, and therefore does not increase our diluted shares outstanding.

For each period presented, our net income (loss) allocable to both common shareholders and diluted common shareholders is the same as our net income (loss) in our consolidated statements of operations.

Share-Based Compensation. Annually, the Compensation Committee grants restricted units of our common stock to certain of our key executives and employees and restricted common stock to our nonemployee directors. The restricted stock units granted to our key executives and key employees generally vest in full on the third anniversary of the award date, conditional on continued employment through such vesting date. The restricted stock unit grants can vest pro rata over three years, provided the individual meets certain age and years-of-service requirements. The grants of restricted stock to our nonemployee directors generally vest in full on the first anniversary of the award date, conditional upon continued service as a director, except for the 2023 grant to one director who retired from our board of directors as of the date of our annual meeting of shareholders in May 2023, which restricted stock grant vested on that date. Each grantee of shares of restricted stock is deemed to be the record owner of those shares during the restriction period, with the right to vote and receive any dividends on those shares. The restricted stock units outstanding have no voting or dividend rights.

17

Table of Contents

For each of the restricted stock units granted in 2021 through September 30, 2023, at the earlier of three years after grant or at termination of employment or service, the grantee will be issued one share of our common stock for each unit vested. As of September 30, 2023 and December 31, 2022, respective totals of 2,327,970 and 2,535,807 shares of restricted stock and restricted stock units were outstanding.

We estimate that share-based compensation cost not yet recognized related to shares of restricted stock or restricted stock units, based on their grant-date fair values, was $13 million as of September 30, 2023. This expense is being recognized on a graded-vesting basis over three years for awards attributable to individuals meeting certain age and years-of-service requirements, and on a straight-line basis over the applicable vesting period of one or three years for the other awards.

Share Repurchase Plan. In December 2014, our Board of Directors approved a share repurchase program under which we may repurchase up to 10 million shares of our common stock on a discretionary basis. Under the program, which has no expiration date, we had repurchased 2.0 million shares for $100 million through December 31, 2015. We have not repurchased any shares under this plan since 2015 and are not obligated to make any future repurchases. We account for the shares we hold in treasury under the cost method, at average cost.

10.            SUBSEQUENT EVENTS

On October 2, 2023, we completed a private placement of $200 million aggregate principal amount of the New 2028 Senior Notes to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act and to non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act. The New 2028 Senior Notes constitute an additional issuance of the Existing 2028 Senior Notes, which we issued in February 2018, in an aggregate principal amount of $300 million, and form a single series with such notes. We will pay interest on the New 2028 Senior Notes on February 1 and August 1 of each year, commencing on February 1, 2024. The New 2028 Senior Notes are scheduled to mature on February 1, 2028. We may redeem some or all of the New 2028 Senior Notes at specified redemption prices. We received net proceeds from the offering of the New 2028 Senior Notes of approximately $180 million after deducting the initial purchasers’ discounts.

On October 2, 2023, we used the net proceeds from the offering discussed above, together with cash on hand, to fund our offer to purchase (the “Tender Offer”) for cash any and all of the $400 million principal amount outstanding of the 2024 Senior Notes. We repurchased $312 million principal amount of the 2024 Senior Notes at par plus accrued and unpaid interest of $5.5 million for approximately $318 million. The consummation of the Tender Offer was contingent upon the completion of the offering discussed above, which was satisfied on October 2, 2023.

On October 2, 2023, we delivered a notice to the holders of the 2024 Senior Notes that we have elected to redeem all of the remaining $88 million principal amount outstanding of the 2024 Senior Notes on the Redemption Date pursuant to our optional redemption right under the indenture governing the 2024 Senior Notes. The redemption price will be equal to 100% of the principal amount of the 2024 Senior Notes plus accrued and unpaid interest up to but not including the Redemption Date plus a “make-whole premium.” We intend to finance the redemption of the 2024 Senior Notes with cash on hand. Upon retirement of the 2024 Senior Notes, we will write off the related unamortized interest rate swaps and debt issuance cost balances.

Item 2.Management's Discussion and Analysis of Financial Condition and Results of Operations

Certain statements we make in this quarterly report on Form 10-Q are forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These statements include, without limitation, statements regarding our expectations about:

•increased costs to operate our business, including the availability and market for our chartered vessels;

•future demand, order intake and business activity levels;

•the collectability of accounts receivable and realizability of contract assets at the amounts reflected on our most-recent balance sheet;

•the backlog of our Manufactured Products segment, to the extent backlog may be an indicator of future revenue or productivity;

•tax refunds and the expected timing thereof;

•the adequacy of our liquidity, cash flows and capital resources to support our operations and internally generated growth initiatives;

•the condition of the debt markets, our possible future debt repurchases and future disclosures regarding the same;

•shares that may be repurchased under our share repurchase plan;

•our expectations about the balance between energy transition and energy security;

•seasonality; and

•industry conditions.

These forward-looking statements are subject to various risks, uncertainties and assumptions, including those we have referred to under the heading “Risk Factors” in Item 1A of this report and under the headings “Risk Factors” and “Cautionary Statement Concerning Forward-Looking Statements” in Part I of our annual report on Form 10-K for the year ended December 31, 2022. Although we believe that the expectations reflected in such forward-looking statements are reasonable, because of the inherent limitations in the forecasting process, as well as the relatively volatile nature of the industries in which we operate, we can give no assurance that those expectations will prove to have been correct. Accordingly, evaluation of our future prospects must be made with caution when relying on forward-looking information.

The following discussion should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our annual report on Form 10-K for the year ended December 31, 2022.

Overview of our Results

Our diluted earnings (loss) per share for the three- and nine-month periods ended September 30, 2023, were $0.29 and $0.52, respectively, as compared to $0.19 in the immediately preceding quarter and $0.18 and $0.03, respectively, for the corresponding periods of the prior year. Our third quarter 2023 results improved as compared to the second quarter of 2023, primarily due to increased activity and improved pricing in our Offshore Projects Group (“OPG”) and Subsea Robotics segments. In addition, we saw improvements in our Aerospace and Defense Technologies (“ADTech”) segment operating results.

During the nine-month period ended September 30, 2023, we utilized $40 million of cash for maintenance capital expenditures and $27 million for growth capital expenditures, partially offset by $57 million of cash provided by operating activities. These items were the largest contributors to our $12 million cash reduction during the nine months ended September 30, 2023.

Results of Operations

We operate in five business segments. Our segments are contained within two businesses—services and products provided primarily to the oil and gas industry, and to a lesser extent, the mobility solutions and offshore renewables industries, among others (“Energy”), and services and products provided to non-energy industries (ADTech). Our four business segments within the Energy business are Subsea Robotics, Manufactured Products, OPG and

21

Table of Contents

Integrity Management & Digital Solutions (“IMDS”). We report our ADTech business as one segment. Our Unallocated Expenses are those not associated with a specific business segment.

Consolidated revenue and profitability information are as follows:

We generate a material amount of our consolidated revenue from contracts for services in the U.S. Gulf of Mexico in our OPG segment, which is usually more active in the second and third quarters, as compared to the rest of the year. The European operations of our IMDS segment are also seasonally more active in the second and third quarters. Revenue in our Subsea Robotics segment is subject to seasonal variations in demand, with our first quarter generally being the low quarter of the year. The level of our Subsea Robotics seasonality depends on the number of Remotely Operated Vehicles (“ROVs”) we have engaged in vessel-based subsea infrastructure inspection, maintenance, repair and installation, which is more seasonal than drilling support. Revenue in each of our Manufactured Products and ADTech segments generally has not been seasonal.

Energy

The primary focus of our Energy business over the last several years has been toward instituting operational efficiency programs that leverage our asset base and capabilities for providing services and products for offshore energy operations and subsea completions, as well as the offshore renewables energy market. These efforts are benefiting us given the continuing increase in global demand for energy which is resulting in improved offshore activity.

The table that follows sets out revenue and profitability for the business segments within our Energy business. In the Subsea Robotics section of the table that follows, “ROV days available” includes all days from the first day that a remotely operated vehicle (“ROV”) is placed into service until the ROV is retired. All days in this period are considered available days, including periods when an ROV is undergoing maintenance or repairs. Our ROVs do not have scheduled maintenance or repair that requires significant time during which the ROVs are not available for utilization.

Subsea Robotics. We believe we are the world’s largest provider of work-class ROV services and, generally, this business segment has been the largest contributor to our Energy business operating income. Our Subsea Robotics segment revenue reflects the utilization percentages, fleet sizes and average pricing in the respective periods. Our survey services business provides survey and positioning, and geoscience services. The following table presents revenue from ROV as a percentage of total Subsea Robotics revenue:

	Three Months Ended						Nine Months Ended

Table of Contents

During the third quarter of 2023, both Subsea Robotics operating income and revenue increased as compared to the immediately preceding quarter, with slight ROV pricing improvements and higher survey activity being partially offset by lower levels of ROV activity. Subsea Robotics operating income and revenue for the three- and nine-month periods ended September 30, 2023, increased as compared to the corresponding periods of the prior year, as a result of higher levels of activity and higher average revenue per day on hire in the first nine months of 2023.

For the three-month period ended September 30, 2023, days on hire decreased when compared to the immediately preceding quarter, with drill support days lower and vessel-based services days higher. Fleet utilization was 69% in the three-month period ended September 30, 2023, as compared to 67% for the corresponding period of the prior year and 70% for the immediately preceding quarter. Fleet utilization increased to 68% from 61% for the nine-month periods ended September 30, 2023 and 2022, respectively. We retired five of our conventional work-class ROV systems and replaced them with five upgraded conventional work-class ROV systems during the nine months ended September 30, 2023, resulting in a total of 250 ROVs in our ROV fleet as of both September 30, 2023 and September 30, 2022.

Manufactured Products. Our Manufactured Products segment provides distribution systems such as production control umbilicals and connection systems made up of specialty subsea hardware, and provides turnkey solutions that include program management, engineering design, fabrication/assembly and installation of autonomous mobile robotic technology to industrial, manufacturing, healthcare, warehousing and commercial theme park markets.

For the three-month period ended September 30, 2023, our Manufactured Products operating results decreased on lower revenue as compared to the immediately preceding quarter, primarily due to changes in product mix. Manufactured Products operating results increased for the three- and nine-month periods ended September 30, 2023, on higher revenue as compared to the corresponding periods of the prior year primarily due to strong order intake in 2022 leading to increased utilization in 2023.

Our Manufactured Products backlog was $556 million as of September 30, 2023, compared to $467 million as of December 31, 2022, and $365 million as of September 30, 2022. Our book-to-bill ratio was 1.41 for the trailing 12 months ended September 30, 2023, as compared to 1.39 for the year ended December 31, 2022, and 1.08 for the trailing 12 months ended September 30, 2022.

Offshore Projects Group. Our OPG segment provides a broad portfolio of integrated subsea project capabilities and solutions as follows:

•subsea installation and intervention, including riserless light well intervention (“RLWI”) services, inspection, maintenance and repair (“IMR”) services, principally in the U.S. Gulf of Mexico and offshore Angola, utilizing owned and chartered vessels;

•installation and workover control systems (“IWOCS”) and ROV workover control systems (“RWOCS”);

•diving services;

•project management and engineering; and

•drill pipe riser services and systems and wellhead load relief solutions.

Our OPG segment operating results improved on higher revenue resulting from strong seasonal demand and international activity during the three months ended September 30, 2023, as compared to the immediately preceding quarter, primarily due to increased demand for vessel-based services globally, changes in service mix and the successful resolution of a commercial dispute. Our OPG operating results were higher on lower revenue in the three months ended September 30, 2023, compared to the corresponding period of the prior year, primarily due to increased activity and utilization in the Africa region during the third quarter of 2023. Our OPG operating results improved on higher revenue in the nine months ended September 30, 2023, as compared to the corresponding period of the prior year, primarily due to increased activity and utilization in the United Kingdom and Asia-Pacific regions, partially offset by reduced vessel work in the Gulf of Mexico.

Integrity Management & Digital Solutions. Our IMDS segment provides asset integrity management, corrosion management, inspection and nondestructive testing services, principally to customers in the oil and gas, power generation and petrochemical industries. We perform these services at onshore and offshore facilities, both topside and subsea. We also provide software, digital and connectivity solutions for the energy industry and software and analytical solutions for the maritime industry.

24

Table of Contents

Our IMDS operating results for the three months ended September 30, 2023 declined slightly, as compared to the immediately preceding quarter primarily due to slight changes in geographic and service mix. IMDS operating results for the three- and nine-month periods ended September 30, 2023, were slightly higher when compared to the corresponding periods of the prior year, primarily due to higher activity levels.

Aerospace and Defense Technologies. Our ADTech segment provides government services and products, including engineering and related manufacturing in defense and space exploration activities, principally to U.S. government agencies and their prime contractors.

Revenue, gross margin and operating income (loss) information for our ADTech segment are as follows:

Our ADTech segment operating results for the third quarter of 2023 increased significantly as compared to the immediately preceding quarter, on higher revenue due to increased activity in our defense subsea technologies and space systems businesses. These improved results benefited from contract costs in the second quarter of 2023 that were not replicated in the three-month period ended September 30, 2023. ADTech operating results for the three- and nine-month periods ended September 30, 2023 were higher when compared to the corresponding periods of the prior year, on increased revenue due to increased activity in all of our government-focused businesses.

Unallocated Expenses

Our Unallocated Expenses (i.e., those not associated with a specific business segment) within gross margin consist of expenses related to our incentive and deferred compensation plans, including restricted stock units, performance units and bonuses, as well as other general expenses. Our Unallocated Expenses within operating expense consist of those expenses within gross margin plus general and administrative expenses related to corporate functions.

The following table sets forth our Unallocated Expenses for the periods indicated:

	Three Months Ended								Nine Months Ended
(dollars in thousands)	Sep 30, 2023			Sep 30, 2022			Jun 30, 2023		Sep 30, 2023			Sep 30, 2022
Gross margin expenses	$	(25,565)		$	(19,417)		(23,685)		$	(73,043)		$	(59,991)

Operating expenses % of revenue	7		%	6		%	6	%	6		%	6		%

Our unallocated operating expenses for the third quarter of 2023 increased as compared to the immediately preceding quarter primarily due to higher accruals in the third quarter of 2023 for incentive-based compensation and increased technology costs. Our Unallocated operating expenses for the three-month period ended September 30, 2023 were higher as compared to the corresponding period of the prior year primarily due to increased accruals in 2023 for incentive-based compensation. Our Unallocated operating expenses for the nine-month period ended September 30, 2023 increased as compared to the corresponding period of the prior year primarily due to higher accruals in 2023 for incentive-based compensation and increased information technology costs.

The following table sets forth our significant financial statement items below the income (loss) from operations line.

Interest income for the three- and nine-month periods ended September 30, 2023, as compared to the three- and nine-month periods ended September 30, 2022, increased primarily due to higher interest rates and increased average amounts of cash invested.

In addition to interest on borrowings, interest expense includes amortization of loan costs and interest rate swap settlements, fees for lender commitments under our senior secured revolving credit agreement and fees for standby letters of credit and bank guarantees that banks issue on our behalf for performance bonds, bid bonds and self-insurance requirements.

Foreign currency transaction gains and losses are the principal component of other income (expense), net. In the three-month periods ended September 30, 2023 and 2022, we incurred foreign currency transaction gains (losses) of $0.9 million and $(1.1) million, respectively. In the nine-month periods ended September 30, 2023 and 2022, we incurred foreign currency transaction gains (losses) of $(3.6) million and $0.2 million, respectively. The currency gains (losses) in the 2023 and 2022 periods were primarily related to increasing (declining) exchange rates for the Angolan kwanza relative to the U.S. dollar. We could incur further foreign currency transaction gains (losses) due to foreign currency exchange fluctuations in Angola and in other countries.

Our tax provision is based on (1) our earnings for the period and other factors affecting the tax provision and (2) the operations of foreign branches and subsidiaries that are subject to local income and withholding taxes. Factors that affect our tax rate include our profitability levels in general and the geographical mix of our results. The effective tax rate for the three- and nine-month periods ended September 30, 2023 and 2022, was different than the federal statutory rate of 21%, primarily due to the geographical mix of revenue and earnings, changes in valuation allowances and uncertain tax positions, and other discrete items. We do not believe a comparison of the effective tax rate for the three- and nine-month periods ended September 30, 2023 and 2022, is meaningful. We continue to make an assertion to indefinitely reinvest the unrepatriated earnings of any foreign subsidiary that would incur material tax consequences upon the distribution of such earnings.

During the nine-month period ended September 30, 2023, we received refunds of $23 million, including interest of $1.7 million which was recorded as a tax benefit, under the U.S. Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The outstanding refund of $20 million was classified as other noncurrent assets on our consolidated balance sheet as of December 31, 2022.

Our income tax payments, excluding the aforementioned CARES Act refund we received in the second quarter of 2023, for the full year of 2023 are estimated to be in the range of $70 million to $75 million, which includes taxes incurred in countries that impose tax on the basis of in-country revenue, without regard to the profitability of such operations.

Liquidity and Capital Resources

We consider our liquidity and capital resources adequate to support our operations, capital commitments and growth initiatives. Our ability to generate substantial cash flow over the last several years has allowed us to grow our cash balance considerably. As of September 30, 2023, we had working capital of $658 million, including cash and cash equivalents of $556 million. Additionally, as of September 30, 2023, we had $215 million of unused commitments through our senior secured revolving credit agreement that we entered into in April 2022 (as amended by an Agreement and Amendment No. 1 to Credit Agreement, dated September 20, 2023, the “Revolving Credit

26

Table of Contents

Agreement”), which is further described below and in Note 6—“Debt” in the Notes to Consolidated Financial Statements included in this quarterly report. Availability under the $215 million revolving credit facility (the “Revolving Credit Facility”) may be limited by certain financial covenants and the requirement that any borrowing under the Revolving Credit Facility not require the granting of any liens to secure any senior notes issued by us (“Senior Notes”). The indentures governing the 2024 Senior Notes (defined below) and the 2028 Senior Notes (defined below) generally limit our ability to incur secured debt for borrowed money (such as borrowings under the Revolving Credit Facility) to 15% of our Consolidated Net Tangible Assets (as defined in such indentures).

On March 19, 2023, following the intervention of the Swiss Federal Department of Finance, the Swiss National Bank and the Swiss Financial Market Supervisory Authority (“FINMA”), Credit Suisse Group AG (“Credit Suisse”) and UBS Group AG (“UBS”) entered into a merger agreement with UBS as the surviving entity. As a result, UBS became a lender under the Revolving Credit Facility. In connection with the amendment of our Revolving Credit Facility in September 2023, Citibank, N.A. replaced UBS as a lender thereunder and assumed the underlying Credit Suisse commitments under the Revolving Credit Agreement.

In 2021, we repurchased $100 million in aggregate principal amount of our 4.650% Senior Notes due 2024 (the “2024 Senior Notes”) in open-market transactions. On October 2, 2023, we repurchased $312 million principal amount of the 2024 Senior Notes at par plus accrued and unpaid interest of $5.5 million for approximately $318 million in the Tender Offer (as defined herein). On October 2, 2023, we delivered a notice to the holders of the 2024 Senior Notes that we have elected to redeem all of the remaining $88 million principal amount outstanding of the 2024 Senior Notes on November 2, 2023 (the “Redemption Date”), pursuant to our optional redemption right under the indenture governing the 2024 Senior Notes. The redemption price will be equal to 100% of the principal amount of the 2024 Senior Notes plus accrued and unpaid interest up to but not including the Redemption Date plus a “make-whole premium.” We intend to finance the redemption of the 2024 Senior Notes with cash on hand. See “—Financing Activities” and Note 10—“Subsequent Events” in the Notes to Consolidated Financial Statements included in this quarterly report for additional information on the Tender Offer and the redemption of the 2024 Senior Notes.

We may, from time to time, complete repurchases of the 2028 Senior Notes (defined below), via open-market or privately negotiated repurchase transactions or otherwise, prior to their maturity date. We can provide no assurances as to the timing of any such repurchases or whether we will complete any such repurchases at all. We do not intend to disclose further information regarding any such repurchase transactions, except to the extent required in our subsequent periodic filings on Forms 10-K or 10-Q, or unless otherwise required by applicable law. See “—Financing Activities” and Note 10—“Subsequent Events” in the Notes to Consolidated Financial Statements included in this quarterly report for additional information on the private placement of our new 2028 Senior Notes.

We have several deepwater vessels under a mix of short-term charters where we can see firm workload and spot charters as market opportunities arise, along with four long-term charters that began in 2022. During the second quarter of 2023, we entered into three new long-term charters for deepwater vessels, two of which began in the third quarter of 2023 and the other that will begin in the first quarter of 2024. We also entered into a contract that will begin in the fourth quarter of 2023 to extend the charter for one of the deepwater vessels we currently utilize. These contracts increased our future contractual obligations for operating lease liabilities by $26 million in 2023, $178 million in the years 2024 and 2025 combined and $56 million in the years 2026 and 2027 combined. There have been no other material changes in our contractual obligations from those disclosed in Part II. Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Contractual Obligations,” of our annual report on Form 10-K for the year ended December 31, 2022. With the current market conditions, we may add additional chartered vessels throughout the year to align with our strategy that balances vessel cost, availability and capability to capture work. We expect to do this through the continued utilization of a mix of short-term, spot and long-term charters.

Our primary sources and uses of cash from operating activities for the nine months ended September 30, 2023 and 2022, are as follows:

		Nine Months Ended
	(in thousands)	Sep 30, 2023		Sep 30, 2022
Cash Flows from Operating Activities:

	Other changes	13,734		(10,535)
	Net Cash Provided by (Used in) Operating Activities	$	57,140	$	(38,583)

The decrease in cash related to accounts receivable and contract assets in the nine months ended September 30, 2023, reflects the timing of project milestones and customer payments. The decrease in cash related to inventory in the nine months ended September 30, 2023, was primarily due to higher activity and related increases in our Manufactured Products and Subsea Robotics inventory. The increase in cash related to current liabilities in the nine months ended September 30, 2023, reflects the timing of vendor payments.

Investing activities

Our capital expenditures of $67 million were higher during the first nine months of 2023, as compared to $55 million in the first nine months of 2022, primarily due to increased capital expenditures in our Subsea Robotics segment.

For 2023, we expect our organic capital expenditures to total between $95 million to $105 million. This includes approximately $45 million to $50 million of maintenance capital expenditures and $50 million to $55 million of growth capital expenditures.

Financing activities

In the nine months ended September 30, 2023 and 2022, we used $5.1 million and $1.9 million, respectively, of cash in financing activities primarily due to payment of tax withholding related to vesting of stock awards.

As of September 30, 2023, we had long-term debt in the principal amount of $700 million outstanding and $215 million of unused commitments under the Revolving Credit Agreement. On September 20, 2023, we entered into an Agreement and Amendment No. 1 to the Revolving Credit Agreement which extended the maturity of the commitments thereunder to April 8, 2027. As of September 30, 2023, we were in compliance with all the covenants set forth in the Revolving Credit Agreement.

In November 2014, we completed the public offering of $500 million aggregate principal amount of the 2024 Senior Notes. We pay interest on the 2024 Senior Notes on May 15 and November 15 of each year. The 2024 Senior Notes are scheduled to mature on November 15, 2024.

In February 2018, we completed the public offering of $300 million aggregate principal amount of 6.000% Senior Notes due 2028 (the “Existing 2028 Senior Notes”). We pay interest on the Existing 2028 Senior Notes on February 1 and August 1 of each year. The Existing 2028 Senior Notes are scheduled to mature on February 1, 2028.

We may redeem some or all of the Existing 2028 Senior Notes at specified redemption prices. In 2021, we repurchased $100 million in aggregate principal amount of the 2024 Senior Notes in open-market transactions.

On October 2, 2023, we completed a private placement of $200 million aggregate principal amount of additional 2028 Senior Notes (the “New 2028 Senior Notes” and, together with the Existing 2028 Senior Notes, the “2028 Senior Notes”) to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to non-U.S. persons outside the United Stated pursuant to Regulation S Under the Securities Act. The New 2028 Senior Notes constitute an additional issuance of the Existing 2028 Senior Notes and form a single series with such notes. We will pay interest on the New 2028 Senior Notes on February 1 and August 1 of each year, commencing on February 1, 2024. The New 2028 Senior Notes are scheduled to mature on February 1, 2028. We may redeem some or all of the New 2028 Senior Notes at specified redemption prices. We received net proceeds from the offering of the New 2028 Senior Notes of approximately $179 million, after deducting the initial purchasers’ discounts and offering expenses.

On October 2, 2023, we used the net proceeds from the offering discussed above, together with cash on hand, to fund our offer to purchase (the “Tender Offer”) for cash any and all of the $400 million principal amount outstanding of the 2024 Senior Notes. We repurchased $312 million principal amount of the 2024 Senior Notes at par plus accrued and unpaid interest of $5.5 million for approximately $318 million. The consummation of the Tender Offer was contingent upon the completion of the offering discussed above, which was satisfied on October 2, 2023.

On October 2, 2023, we delivered a notice to the holders of the 2024 Senior Notes that we have elected to redeem all of the remaining $88 million principal amount outstanding of the 2024 Senior Notes on the Redemption Date pursuant to our optional redemption right under the indenture governing the 2024 Senior Notes. The redemption price will be equal to 100% of the principal amount of the 2024 Senior Notes plus accrued and unpaid interest up to but not including the Redemption Date plus a “make-whole premium.” We intend to finance the redemption of the 2024 Senior Notes with cash on hand.

In December 2014, our Board of Directors approved a plan to repurchase up to 10 million shares of our common stock. In 2015, we repurchased 2.0 million shares under this plan. We have not repurchased any shares under this plan since December 2015. We account for the shares we hold in treasury under the cost method, at average cost. The timing and amount of any future repurchases will be determined by our management. We expect that any additional shares repurchased under the plan will be held as treasury stock for possible future use. The plan does not obligate us to repurchase any particular number of shares.

Off-Balance Sheet Arrangements

We have not guaranteed any debt not reflected on our Consolidated Balance Sheets as of September 30, 2023, and we do not have any off-balance sheet arrangements, as defined by Securities and Exchange Commission's rules.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in conformity with accounting principles generally accepted in the United States. These principles require us to make various estimates, judgments and assumptions that affect the reported amounts in our financial statements and accompanying notes. We disclose our significant accounting policies in Notes to Consolidated Financial Statements—Note 1—“Summary of Major Accounting Policies” in this quarterly report and in our annual report on Form 10-K for the year ended December 31, 2022, in Part II. Item 7. “Financial Statements and Supplementary Data—Note 1—Summary of Major Accounting Policies.”

Item 3.Quantitative and Qualitative Disclosures About Market Risk

We are exposed to certain market risks arising from transactions we enter into in the normal course of business. These risks relate to interest rate changes and fluctuations in foreign exchange rates. Except for our exposure in Angola, we do not believe these risks are material. We have not entered into any market-risk-sensitive instruments for speculative or trading purposes. When we have a significant amount of borrowings, we typically manage our exposure to interest rate changes through the use of a combination of fixed- and floating-rate debt. See Note 6—“Debt” in the Notes to Consolidated Financial Statements included in this quarterly report for a description of our Revolving Credit Agreement and interest rates on our borrowings. We believe significant interest rate changes would not have a material near-term impact on our future earnings or cash flows.

Because we operate in various regions in the world, we conduct a portion of our business in currencies other than the U.S. dollar. The functional currency for most of our international operations is the applicable local currency. A stronger U.S. dollar against the United Kingdom pound sterling, the Norwegian kroner and the Brazilian real could result in lower operating income. We manage our exposure to changes in foreign exchange rates by primarily denominating our contracts and providing for collections from our customers in U.S. dollars or freely convertible currency and endeavoring to match our contract costs with the denominated contractual currency. We use the exchange rates in effect as of the balance sheet date to translate assets and liabilities when the functional currency is the local currency, resulting in translation adjustments that we reflect as accumulated other comprehensive income or loss in the equity section of our Consolidated Balance Sheets. We recorded net adjustments to our equity accounts of $(11) million and $(21) million in the three-month periods ended September 30, 2023 and 2022, respectively, and $(10) million and $(42) million in the nine-month periods ended September 30, 2023 and 2022, respectively. Negative adjustments reflect the net impact of the strengthening of the U.S. dollar against various foreign currencies for locations where the functional currency is not the U.S. dollar. Conversely, positive adjustments reflect the effect of a weakening U.S. dollar.

We recorded foreign currency transaction gains (losses) of $0.9 million and $(1.1) million in the three-month periods ended September 30, 2023 and 2022, respectively, and $(3.6) million and $0.2 million in the nine-month periods ended September 30, 2023 and 2022, respectively. We recorded foreign currency transaction gains (losses) related to the Angolan kwanza as a component of other income (expense), net in our Consolidated Statements of Operations in those respective periods. Foreign currency transaction gains (losses) related to the Angolan kwanza of $0.8 million and $(1.4) million in three-month periods ended September 30, 2023 and 2022, respectively, and $(5.2) million and $0.7 million in the nine-month periods ended September 30, 2023 and 2022, respectively, were primarily due to the remeasurement of our Angolan kwanza cash balances to U.S. dollars.

The Angolan kwanza was devalued against the U.S. dollar by 65% in the nine-month period ended September 30, 2023. Any conversion of cash balances from kwanza to U.S. dollars is controlled by the central bank in Angola. During 2023, we have repatriated $1.8 million in cash from Angola. As of September 30, 2023 and December 31, 2022, we had the equivalent of approximately $13 million and $5.6 million, respectively, of kwanza cash balances in Angola reflected on our Consolidated Balance Sheets.

To mitigate our currency exposure risk in Angola, we used kwanza to purchase equivalent Angolan central bank (Banco Nacional de Angola) bonds. The bonds were denominated as U.S. dollar equivalents, so that, upon payment of semi-annual interest and principal upon maturity, payment was made in kwanza, equivalent to the respective U.S. dollars at the then-current exchange rate. Our remaining Angolan bonds matured on September 1, 2023, and we received cash proceeds of $6.2 million. As of December 31, 2022, we had $6.2 million of U.S. dollar equivalent Angolan bonds. These bonds were classified as available-for-sale securities; accordingly, they were recorded at fair market value in other current assets in our Consolidated Balance Sheets as of December 31, 2022. We did not sell any of our Angolan bonds in the three- and nine-month periods ended September 30, 2022.

We estimated the fair market value of the Angolan bonds to be $6.4 million as of December 31, 2022, using quoted market prices. Since the market for the Angolan bonds was not an active market, the fair value of the Angolan bonds was classified within Level 2 in the fair value hierarchy under U.S. GAAP. As of December 31, 2022, we had $0.1 million in unrealized gains, net of tax, related to these bonds as a component of accumulated other comprehensive loss on our Consolidated Balance Sheets.

Item 4.        Controls and Procedures

In accordance with Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we carried out an evaluation, under the supervision and with the participation of management, including our principal executive officer and principal financial officer, of the effectiveness of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of September 30, 2023, to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms.

There has been no change in our internal control over financial reporting that occurred during the three months ended September 30, 2023, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1.Legal Proceedings

For information regarding legal proceedings, see the discussion under the caption “Litigation” in Note 7—“Commitments and Contingencies” in the Notes to Consolidated Financial Statements included in this report, which discussion we incorporate by reference into this Item.

Item 1A.    Risk Factors

With the exception of the following, there have been no other material changes in our risk factors from those

disclosed in Part I, Item 1A, of our annual report on Form 10-K for the year ended December 31, 2022.

Difficulty in obtaining sufficient capital could adversely impact our business and financial condition.

A financial crisis or economic recession could have an adverse impact on our business and our financial condition. In particular, the cost of capital could increase substantially and the availability of funds from the capital markets could diminish significantly. Since the global recession in 2008, credit and capital markets have, from time to time, experienced unusual volatility. Our ability to access the capital markets in the future could be restricted or available on terms we do not consider favorable. Furthermore, if investors or financial institutions shift funding away from companies in the energy industry, our access to capital or the market for our securities could be negatively impacted. Limited access to the capital markets could adversely impact our ability to take advantage of business opportunities or react to changing economic and business conditions and could adversely impact our ability to continue our growth strategy. Ultimately, we could be required to reduce our future capital expenditures substantially. Such a reduction could have a material adverse effect on our business and our consolidated financial condition, results of operations and cash flows. A financial crisis or economic recession could also affect our suppliers and our customers, causing them to fail to meet their obligations to us, which could have a material adverse effect on our revenue, income from operations and cash flows.

If one or more of the lenders under our revolving credit facility were to become unable or unwilling to perform their obligations under that facility, our borrowing capacity could be reduced. Our inability to borrow under our revolving credit facility could limit our ability to fund our future operations and growth.

In addition, we maintain our cash balances and short-term investments primarily in accounts held by major banks and financial institutions located principally in North America, Europe, Africa and Asia, and some of those accounts hold deposits that exceed available insurance. It is possible that one or more of the financial institutions in which we hold our cash and investments could become subject to bankruptcy, receivership or similar proceedings. As a result, we could be at risk of not being able to access material amounts of our cash, which could result in a temporary liquidity crisis that could impede our ability to fund operations.

Item 5.    Other Information

During the three-month period ended September 30, 2023, no director or officer of the Company adopted or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.

Accounting Policies [Abstract]

Allowance for Credit Losses [Text Block]

Allowances for Credit Loss—Financial Assets Measured at Amortized Costs. We identify our allowance for credit losses based on future expected losses when accounts receivable, contract assets or held-to-maturity loan receivables are created rather than when losses are probable.

We use the loss-rate method in developing the allowance for credit losses, which involves identifying pools of assets with similar risk characteristics, reviewing historical losses within the last three years and consideration of reasonable supportable forecasts of economic indicators. Changes in estimates, developing trends and other new information could have material effects on future evaluations.

We monitor the credit quality of our accounts receivable and other financing receivable amounts by frequent customer interaction, following economic and industry trends and reviewing specific customer data. Our other receivable amounts include contract assets and held-to-maturity loans receivable, which we consider to have a low risk of loss.

We consider macroeconomic conditions when assessing our credit risk exposure, including any impacts from the conflicts in Russia and Ukraine and in the Middle East and volatility in the financial services industry and the oil and natural gas markets, and the effects thereof on our customers and various counterparties. We have determined the impacts to our credit loss expenses are de minimis for the three- and nine-month periods ended September 30, 2023 and 2022.

As of September 30, 2023, our allowance for credit losses was $2.1 million for accounts receivable and $0.6 million for other receivables. As of December 31, 2022, our allowance for credit losses was $2.0 million for accounts receivable and $0.3 million for other receivables. Our allowance for credit losses increased in the nine months

ended September 30, 2023, as compared to the same period in the prior year, primarily due to corresponding increases in revenue and accounts receivable.

Financial assets are written off when deemed uncollectible and there is no reasonable expectation of recovering the contractual cash flows. During the three- and nine-month periods ended September 30, 2023, we did not write off any financial assets. In the three months ended September 30, 2023, we received cash proceeds of $1.8 million as partial recovery of a previously written off financial asset.

Accounts receivable are considered to be past due after the end of the contractual terms agreed to with the customer. There were no material past due amounts that we consider uncollectible for our financial assets as of September 30, 2023. We generally do not require collateral from our customers.

Accounting Policies [Abstract]

Allowance for Credit Losses [Text Block]

Allowances for Credit Loss—Financial Assets Measured at Amortized Costs. We identify our allowance for credit losses based on future expected losses when accounts receivable, contract assets or held-to-maturity loan receivables are created rather than when losses are probable.

We use the loss-rate method in developing the allowance for credit losses, which involves identifying pools of assets with similar risk characteristics, reviewing historical losses within the last three years and consideration of reasonable supportable forecasts of economic indicators. Changes in estimates, developing trends and other new information could have material effects on future evaluations.

We monitor the credit quality of our accounts receivable and other financing receivable amounts by frequent customer interaction, following economic and industry trends and reviewing specific customer data. Our other receivable amounts include contract assets and held-to-maturity loans receivable, which we consider to have a low risk of loss.

We consider macroeconomic conditions when assessing our credit risk exposure, including any impacts from the conflicts in Russia and Ukraine and in the Middle East and volatility in the financial services industry and the oil and natural gas markets, and the effects thereof on our customers and various counterparties. We have determined the impacts to our credit loss expenses are de minimis for the three- and nine-month periods ended September 30, 2023 and 2022.

As of September 30, 2023, our allowance for credit losses was $2.1 million for accounts receivable and $0.6 million for other receivables. As of December 31, 2022, our allowance for credit losses was $2.0 million for accounts receivable and $0.3 million for other receivables. Our allowance for credit losses increased in the nine months

ended September 30, 2023, as compared to the same period in the prior year, primarily due to corresponding increases in revenue and accounts receivable.

Financial assets are written off when deemed uncollectible and there is no reasonable expectation of recovering the contractual cash flows. During the three- and nine-month periods ended September 30, 2023, we did not write off any financial assets. In the three months ended September 30, 2023, we received cash proceeds of $1.8 million as partial recovery of a previously written off financial asset.

Accounts receivable are considered to be past due after the end of the contractual terms agreed to with the customer. There were no material past due amounts that we consider uncollectible for our financial assets as of September 30, 2023. We generally do not require collateral from our customers.

Property, Plant, and Equipment and Intangible Assets

Property and Equipment, Long-Lived Intangible Assets and Right-of-Use Operating Lease Assets. We provide for depreciation of property and equipment on the straight-line method over estimated useful lives. We charge the costs of repair and maintenance of property and equipment to operations as incurred, and we capitalize the costs of improvements that extend asset lives or functionality. Upon the disposition of property and equipment, the related cost and accumulated depreciation accounts are relieved, and any resulting gain or loss is recognized as income.

We capitalize interest on assets where the construction period is anticipated to be more than three months. We did not capitalize interest in the three- and nine-month periods ended September 30, 2023 and 2022. We do not allocate general administrative costs to capital projects.

Long-lived intangible assets, primarily acquired in connection with business combinations, include trade names, intellectual property and customer relationships and are being amortized over their respective estimated useful lives.

Our management periodically, and upon the occurrence of a triggering event, reviews the realizability of our property and equipment, long-lived intangible assets and right-of-use operating lease assets to determine whether any events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable. For long-lived assets to be held and used, we base our evaluation on impairment indicators such as the nature of the assets, the future economic benefits of the assets, any historical or future profitability measurements and other external market conditions or factors that may be present. If such impairment indicators are present or other factors exist that indicate that the carrying amount of an asset may not be recoverable, we determine whether an impairment has occurred through the use of an undiscounted cash flows analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, we recognize a loss for the difference between the carrying amount and the fair value of the asset. We did not identify indicators of impairment for property and equipment, long-lived intangible assets or right-of-use operating lease assets for the three- and nine-month periods ended September 30, 2023 and 2022.

For assets held for sale or disposal, the fair value of the asset is measured using fair market value less estimated costs to sell. Assets are classified as held for sale when we have a plan for disposal of certain assets and those assets meet the held for sale criteria.

For additional information regarding right-of-use operating lease assets, see “Leases” below.

Contract Balances

Our contracts with milestone payments have, in the aggregate, a significant impact on the contract asset and the contract liability balances. Milestones are contractually agreed with customers and relate to significant events across the contract lives. Some milestones are achieved before revenue is recognized, resulting in a contract liability, while other milestones are achieved after revenue is recognized, resulting in a contract asset.

The following table provides information about contract assets and contract liabilities from contracts with customers.

Performance Obligations

As of September 30, 2023, the aggregate amount of the transaction price allocated to remaining performance obligations that were unsatisfied (or partially unsatisfied) was $449 million. In arriving at this value, we have used two expedients available to us and are not disclosing amounts in relation to performance obligations: (1) that are part of contracts with an original expected duration of one year or less; or (2) on contracts where we recognize revenue in line with the billing. Of this amount, we expect to recognize revenue of $324 million over the next 12 months, $124 million within the next 24 months and we expect to recognize substantially all of the remaining balance of $2.2 million within the next 36 months.

In our Manufactured Products and ADTech segments, we have long-term contracts that extend beyond one year, and these make up the majority of the performance obligations balance reported as of September 30, 2023. We also have shorter-term product contracts with an expected original duration of one year or less that have been excluded.

Where appropriate, we have made estimates within the transaction price of elements of variable consideration within the contracts and constrained those amounts to a level where we consider it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The amount of revenue recognized in the three- and nine-month periods ended September 30, 2023 and 2022, that was associated with performance obligations completed or partially completed in prior periods was not significant.

As of September 30, 2023, there were no significant outstanding liability balances for refunds or returns due to the nature of our contracts and the services and products we provide. Our warranties are limited to assurance warranties that are of a standard length and are not considered to be material rights. The majority of our contracts consist of a single performance obligation. When there are multiple obligations, we look for observable evidence of stand-alone selling prices on which to base the allocation. This involves judgment as to the appropriateness of the observable evidence relating to the facts and circumstances of the contract. If we do not have observable evidence, we estimate stand-alone selling prices by taking a cost-plus-margin approach, using typical margins from the type of product or service, customer and regional geography involved.

Costs to Obtain or Fulfill a Contract

In line with the available practical expedient, we capitalize incremental costs to obtain a contract that would not have been incurred if the contract had not been obtained when those amounts are significant and the contract is expected at inception to exceed one year in duration. Our costs to obtain a contract primarily consist of bid and proposal costs, which are generally expensed in the period when incurred. There were no balances or amortization of costs to obtain a contract in the current reporting periods.

Costs to fulfill a contract primarily consist of certain mobilization costs incurred to provide services or products to our customers. These costs are deferred and amortized over the period of contract performance. The closing balance of costs to fulfill a contract was $8.1 million and $10 million as of September 30, 2023 and December 31, 2022, respectively. For the three- and nine-month periods ended September 30, 2023, we recorded amortization expense

of $1.2 million and $4.0 million, respectively. For the three- and nine-month periods ended September 30, 2022, we recorded amortization expense of $1.2 million and $4.2 million, respectively. No impairment costs were recognized.

Revenue Recognition. All our revenue is realized through contracts with customers. We recognize our revenue according to the contract type. On a daily basis, we recognize service revenue over time for contracts that provide for specific time, material and equipment charges, which we bill periodically, ranging from weekly to monthly. We use the input method to recognize revenue, because each day of service provided represents value to the customer. The performance obligations in these contracts are satisfied, and revenue is recognized, as the work is performed. When appropriate, we apply the practical expedient to recognize revenue for the amount invoiced when the invoice corresponds directly to the value of our performance to date.

We account for significant fixed-price contracts, mainly relating to our Manufactured Products segment, and to a lesser extent in our Offshore Projects Group (“OPG”) and Aerospace and Defense Technologies (“ADTech”) segments, by recognizing revenue over time using the cost-to-cost input method. A performance obligation is satisfied as we create a product on behalf of the customer over the life of the contract. The remainder of our revenue is recognized at the point in time when control transfers to the customer, thus satisfying the performance obligation.

We have elected to recognize the cost for freight and shipping as an expense when incurred. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, and that are collected by us from customers, are excluded from revenue.

In our service-based business lines, we principally charge on a dayrate basis for services provided. In our product-based business lines, predominantly in our Manufactured Products segment, we recognize revenue and profit using the percentage-of-completion method and exclude uninstalled materials and significant inefficiencies from the measure of progress.

We apply judgment in the determination and allocation of transaction price to performance obligations, and the subsequent recognition of revenue, based on the facts and circumstances of each contract. We routinely review estimates related to our contracts and, when required, reflect revisions to profitability in earnings immediately. If an element of variable consideration has the potential for a significant future reversal of revenue, we will constrain that variable consideration to a level intended to remove the potential future reversal. If a current estimate of total contract cost indicates an ultimate loss on a contract, we recognize the projected loss in full when we determine it. During the three- and nine-month periods ended September 30, 2023, we recognized projected losses of $1.8 million and $4.7 million, respectively, for entertainment business contracts in our Manufactured Products segment. During the three- and nine-month periods ended September 30, 2022, we recognized projected losses of $1.5 million and $4.0 million, respectively, for contracts in our Manufactured Products segment. There could be significant adjustments to overall contract costs in the future, due to changes in facts and circumstances.

In general, our payment terms consist of those services billed regularly as provided and those products delivered at a point in time, which are invoiced after the performance obligation is satisfied. Our product and service contracts with milestone payments due at agreed progress points during the contract are invoiced when those milestones are reached, which may differ from the timing of revenue recognition. Our payment terms generally do not provide financing of contracts to customers, nor do we receive financing from customers as a result of these terms.

See Note 3—“Revenue” for more information on our revenue from contracts with customers.

In November 2014, we completed the public offering of $500 million aggregate principal amount of 4.650% Senior Notes due 2024 (the “2024 Senior Notes”). We pay interest on the 2024 Senior Notes on May 15 and November 15 of each year. The 2024 Senior Notes are scheduled to mature on November 15, 2024. In the year ended December 31, 2021, we repurchased $100 million in aggregate principal amount of the 2024 Senior Notes in open-market transactions. On October 2, 2023, we repurchased $312 million principal amount of the 2024 Senior Notes at par plus accrued and unpaid interest of $5.5 million for approximately $318 million in the Tender Offer (as defined herein). On October 2, 2023, we delivered a notice to the holders of the 2024 Senior Notes that we have elected to redeem all of the remaining $88 million principal amount outstanding of the 2024 Senior Notes on November 2, 2023 (the “Redemption Date”), pursuant to our optional redemption right under the indenture governing the 2024 Senior Notes. The redemption price will be equal to 100% of the principal amount of the 2024 Senior Notes plus accrued and unpaid interest up to but not including the Redemption Date plus a “make-whole premium.” See Note 10—“Subsequent Events” for additional information on the Tender Offer (as defined herein) and the redemption of the 2024 Senior Notes.

In February 2018, we completed the public offering of $300 million aggregate principal amount of 6.000% Senior Notes due 2028 (the “Existing 2028 Senior Notes”). We pay interest on the Existing 2028 Senior Notes on February 1 and August 1 of each year. The Existing 2028 Senior Notes are scheduled to mature on February 1, 2028. We used the net proceeds from the Existing 2028 Senior Notes to repay indebtedness.

We may redeem some or all of the Existing 2028 Senior Notes at specified redemption prices. In the three- and nine-month periods ended September 30, 2023 and 2022, we did not repurchase any of the 2024 Senior Notes or the Existing 2028 Senior Notes.

On October 2, 2023, we completed a private placement of $200 million aggregate principal amount of additional 2028 Senior Notes (the “New 2028 Senior Notes” and, together with the Existing 2028 Senior Notes, the “2028 Senior Notes”) to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act. The New 2028 Senior Notes constitute an additional issuance of the Existing 2028 Senior Notes and form a single series with such notes. We will pay interest on the New 2028 Senior Notes on February 1 and August 1 of each year, commencing on February 1, 2024. The New 2028 Senior Notes are scheduled to mature on February 1, 2028. We may redeem some or all of the New 2028 Senior Notes at specified redemption prices. We received proceeds from the offering of the New 2028 Senior Notes of approximately $180 million, after initial purchasers’ discounts. We used the net proceeds from the New 2028 Senior Notes, together with cash on hand, to fund the Tender Offer (as defined herein). As a result of these transactions, we reclassified approximately $132 million from long-term debt to the current portion of long-term debt as of September 30, 2023. The current portion of long-term debt represents the amount of the 2024 Senior Notes repurchased subsequent to period end utilizing cash on hand as of September 30, 2023, with the remainder repurchased using proceeds from the subsequent issuance of the New 2028 Senior Notes.

On April 8, 2022, we entered into a senior secured revolving credit agreement with a group of banks (as amended by an Agreement and Amendment No. 1 to Credit Agreement, dated September 20, 2023, the “Revolving Credit Agreement”). The commitments under the Revolving Credit Agreement are scheduled to mature on April 8, 2027, or 91 days prior to the maturity date of the 2024 Senior Notes if either we have not prepaid such notes by such date or our Liquidity (as defined in the Revolving Credit Agreement) is less than $175 million on such date. The Revolving Credit Agreement includes a $215 million revolving credit facility (the “Revolving Credit Facility”) with a $100 million sublimit for the issuance of letters of credit. Our obligations under the Revolving Credit Agreement are guaranteed by certain of our wholly owned subsidiaries and are secured by first priority liens on certain of our assets and those of the guarantors, including, among other things, intellectual property, inventory, accounts receivable, equipment and equity interests in subsidiaries. As of September 30, 2023, we had no borrowings outstanding under the Revolving Credit Facility and no letters of credit outstanding under the Revolving Credit Agreement.

We may borrow under the Revolving Credit Facility at either (1) a base rate, determined as the greatest of (A) the prime rate of Wells Fargo Bank, National Association, (B) the federal funds effective rate plus 1⁄2 of 1% and (C) Adjusted Term SOFR (as defined in the Revolving Credit Agreement) for a one-month tenor plus 1%, in each case plus the applicable margin, which varies from 1.25% to 2.25% depending on our Consolidated Net Leverage Ratio (as defined in the Revolving Credit Agreement), or (2) Adjusted Term SOFR plus the applicable margin, which varies from 2.25% to 3.25% depending on our Consolidated Net Leverage Ratio. We will also pay a facility fee based on the amount of the underlying commitment that is being utilized, which fee varies from 0.300% to 0.375%, with the higher rate owed when we use the Revolving Credit Facility less.

The Revolving Credit Agreement includes financial covenants that are tested on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter. The maximum permitted Consolidated Net Leverage Ratio is initially 4.00 to 1.00 and will decrease to 3.25 to 1.00 during the term of the Revolving Credit Facility. As of September 30, 2023, the maximum permitted Consolidated Net Leverage Ratio was 3.50 to 1.00. The minimum Consolidated Interest Coverage Ratio (as defined in the Revolving Credit Agreement) is 3.00 to 1.00 throughout the term of the Revolving Credit Facility. Availability under the Revolving Credit Facility may be limited by these financial covenants and the requirement that any borrowing under the Revolving Credit Facility not require the granting of any liens to secure any senior notes issued by us (“Senior Notes”). The indentures governing the 2024 Senior Notes and the 2028 Senior Notes generally limit our ability to incur secured debt for borrowed money (such as borrowings under the Revolving Credit Facility) to 15% of our Consolidated Net Tangible Assets (as defined in such indentures). As of September 30, 2023, the full $215 million was available to borrow under the Revolving Credit Facility. In addition, the Revolving Credit Agreement contains various covenants that we believe are customary for agreements of this nature, including, but not limited to, restrictions on our ability and the ability of

each of our subsidiaries to incur debt, grant liens, make certain investments, make distributions, merge or consolidate, sell assets and enter into certain restrictive agreements. As of September 30, 2023, we were in compliance with all the covenants set forth in the Revolving Credit Agreement.

We had two interest rate swaps in place relating to a total of $200 million of the 2024 Senior Notes for the period to November 2024. The agreements swapped the fixed interest rate of 4.65% on $100 million of the 2024 Senior Notes to the floating rate of one-month London Interbank Offered Rate (“LIBOR”) plus 2.426% and on another $100 million to one-month LIBOR plus 2.823%. In March 2020, we settled both interest rate swaps with the counterparty for cash proceeds of $13 million. The settlement resulted in a $13 million increase to our long-term debt balance that is being amortized to interest expense through the maturity date for the 2024 Senior Notes using the effective interest method. As a result, we amortized $0.6 million and $1.7 million to interest expense for the three- and nine-month periods ended September 30, 2023, respectively and $0.5 million and $1.6 million to interest expense for the three- and nine-month periods ended September 30, 2022, respectively.

We incurred $6.9 million and $4.2 million of issuance costs related to the 2024 Senior Notes and the Existing 2028 Senior Notes, respectively, and $4.0 million of loan costs related to the Revolving Credit Agreement. These costs, net of accumulated amortization, are included as a reduction of long-term debt on our Consolidated Balance Sheets, as they pertain to the Senior Notes, and in other noncurrent assets, as they pertain to the Revolving Credit Agreement. We are amortizing these costs to interest expense through the respective maturity dates for the Senior Notes and the Revolving Credit Agreement using the straight-line method, which approximates the effective interest rate method. As a result, we amortized $0.5 million and $1.6 million to interest expense for the three- and nine-month periods ended September 30, 2023, respectively, and $0.6 million and $1.6 million to interest expense for the three- and nine-month periods ended September 30, 2022, respectively.

Commitments and Contingencies Disclosure [Abstract]

Contingencies Disclosure

COMMITMENTS AND CONTINGENCIES

Litigation. In the ordinary course of business, we are, from time to time, involved in litigation or subject to disputes, governmental investigations or claims related to our business activities, including, among other things:

•performance- or warranty-related matters under our customer and supplier contracts and other business arrangements; and

•workers’ compensation claims, Jones Act claims, occupational hazard claims, premises liability claims and other claims.

Although we cannot predict the ultimate outcome of these matters, we believe that our ultimate liability, if any, that may result from these other actions and claims will not have a material adverse effect on our consolidated financial condition, results of operations or cash flows. However, because of the inherent uncertainty of litigation and other dispute resolution proceedings and, in some cases, the availability and amount of potentially available insurance, we can provide no assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material effect on our consolidated financial condition, results of operations or cash flows for the fiscal period in which that resolution occurs.

Financial Instruments and Risk Concentration. In the normal course of business, we manage risks associated with foreign exchange rates and interest rates through a variety of strategies, including the use of hedging transactions. As a matter of policy, we do not use derivative instruments unless we have an underlying exposure. Other financial instruments that potentially subject us to concentrations of credit risk are principally cash and cash equivalents and accounts receivable.

The carrying values of cash and cash equivalents approximate their fair values due to the short-term maturity of the underlying instruments. Accounts receivable are generated from a broad group of customers, primarily from the energy industry and the U.S. government, which are major sources of our revenue. Due to their short-term nature, carrying values of our accounts receivable and accounts payable approximate fair market values.

We estimated the aggregate fair market value of the Senior Notes to be $678 million as of September 30, 2023, based on quoted prices. Since the market for the Senior Notes is not an active market, the fair value of the Senior Notes is classified within Level 2 in the fair value hierarchy under U.S. GAAP (inputs other than quoted prices in active markets for similar assets and liabilities that are observable or can be corroborated by observable market data for substantially the full terms for the assets or liabilities).

Foreign currency gains (losses) related to the Angolan kwanza of $0.8 million and $(5.2) million in the three- and nine-month periods ended September 30, 2023, respectively, and $(1.4) million and $0.7 million in the three- and nine-month periods ended September 30, 2022, respectively, were primarily related to increasing (declining) exchange rates for the Angolan kwanza relative to the U.S. dollar. We recorded foreign currency transaction gains (losses) related to the Angolan kwanza as a component of other income (expense), net in our Consolidated Statements of Operations.

Any conversion of cash balances from kwanza to U.S. dollars is controlled by the central bank in Angola. As of September 30, 2023 and December 31, 2022, we had the equivalent of approximately $13 million and $5.6 million, respectively, of kwanza cash balances in Angola reflected on our Consolidated Balance Sheets.

To mitigate our currency exposure risk in Angola, we used kwanza to purchase equivalent Angolan central bank (Banco Nacional de Angola) bonds. The bonds were denominated as U.S. dollar equivalents, so that, upon payment of semi-annual interest and principal upon maturity, payment was made in kwanza, equivalent to the respective U.S. dollars at the then-current exchange rate. Our remaining Angolan bonds matured on September 1, 2023, and we received cash proceeds of $6.2 million.

As of December 31, 2022, we had $6.2 million of U.S. dollar equivalent Angolan bonds. These bonds were classified as available-for-sale securities; accordingly, they were recorded at fair market value in other current assets in our Consolidated Balance Sheets as of December 31, 2022. We did not sell any of our Angolan bonds in the three- and nine-month periods ended September 30, 2022. We estimated the fair market value of the Angolan bonds to be $6.4 million as of December 31, 2022, using quoted market prices. Since the market for the Angolan bonds was not an active market, the fair value of the Angolan bonds was classified within Level 2 in the fair value hierarchy under U.S. GAAP. As of December 31, 2022, we had $0.1 million in unrealized loss, net of tax, related to these bonds as a component of accumulated other comprehensive loss in our Consolidated Balance Sheets.

In the three-month period ended June 30, 2021, we were notified by a customer in our Manufactured Products segment that it was suspending a contract that was substantially complete. Specific to this contract, we billed and received $19 million of accounts receivable during the first nine months of 2023. As of September 30, 2023, we had outstanding contract assets of approximately $20 million for the contract and $3.6 million in contract liabilities. As of December 31, 2022, we had outstanding contract assets of approximately $19 million for the contract and contract liabilities of $0.6 million prepaid for storage of components. We are in discussions with the customer concerning the timing of remaining payments. We continue to believe that we will realize these contract assets at their book values, although we can provide no assurance as to the timing of receipt of the remaining payments.

Earnings (Loss) Per Share, Stock-Based Compensation and Share Repurchase Plan

Shareholders' Equity, Earnings Per Share And Stock-Based Compensation [Abstract]

Shareholders' Equity and Share-based Payments

EARNINGS (LOSS) PER SHARE, SHARE-BASED COMPENSATION AND SHARE REPURCHASE PLAN

Earnings (Loss) per Share. For each period presented, the only difference between our calculated weighted-average basic and diluted number of shares outstanding is the effect of outstanding restricted stock units. In periods where we have a net loss, the effect of our outstanding restricted stock units is anti-dilutive, and therefore does not increase our diluted shares outstanding.

For each period presented, our net income (loss) allocable to both common shareholders and diluted common shareholders is the same as our net income (loss) in our consolidated statements of operations.

Share-Based Compensation. Annually, the Compensation Committee grants restricted units of our common stock to certain of our key executives and employees and restricted common stock to our nonemployee directors. The restricted stock units granted to our key executives and key employees generally vest in full on the third anniversary of the award date, conditional on continued employment through such vesting date. The restricted stock unit grants can vest pro rata over three years, provided the individual meets certain age and years-of-service requirements. The grants of restricted stock to our nonemployee directors generally vest in full on the first anniversary of the award date, conditional upon continued service as a director, except for the 2023 grant to one director who retired from our board of directors as of the date of our annual meeting of shareholders in May 2023, which restricted stock grant vested on that date. Each grantee of shares of restricted stock is deemed to be the record owner of those shares during the restriction period, with the right to vote and receive any dividends on those shares. The restricted stock units outstanding have no voting or dividend rights.

For each of the restricted stock units granted in 2021 through September 30, 2023, at the earlier of three years after grant or at termination of employment or service, the grantee will be issued one share of our common stock for each unit vested. As of September 30, 2023 and December 31, 2022, respective totals of 2,327,970 and 2,535,807 shares of restricted stock and restricted stock units were outstanding.

We estimate that share-based compensation cost not yet recognized related to shares of restricted stock or restricted stock units, based on their grant-date fair values, was $13 million as of September 30, 2023. This expense is being recognized on a graded-vesting basis over three years for awards attributable to individuals meeting certain age and years-of-service requirements, and on a straight-line basis over the applicable vesting period of one or three years for the other awards.

Share Repurchase Plan. In December 2014, our Board of Directors approved a share repurchase program under which we may repurchase up to 10 million shares of our common stock on a discretionary basis. Under the program, which has no expiration date, we had repurchased 2.0 million shares for $100 million through December 31, 2015. We have not repurchased any shares under this plan since 2015 and are not obligated to make any future repurchases. We account for the shares we hold in treasury under the cost method, at average cost.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

INCOME TAXES

Our tax provision is based on (1) our earnings for the period and other factors affecting the tax provision and (2) the operations of foreign branches and subsidiaries that are subject to local income and withholding taxes. Factors that affect our tax rate include our profitability levels in general and the geographical mix of our results. The effective tax rate for the three- and nine-month periods ended September 30, 2023 and 2022, was different than the U.S. federal statutory rate of 21%, primarily due to the geographical mix of revenue and earnings, changes in valuation allowances and uncertain tax positions, and other discrete items. We do not believe a comparison of the effective tax rate for the three- and nine-month periods ended September 30, 2023 and 2022, is meaningful. We continue to make an assertion to indefinitely reinvest the unrepatriated earnings of any foreign subsidiary that would incur material tax consequences upon the distribution of such earnings.

During the nine-month period ended September 30, 2023, we received refunds of $23 million, including interest of $1.7 million, which was recorded as a tax benefit under the U.S. Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The outstanding refund of $20 million was classified as other noncurrent assets on our consolidated balance sheet as of December 31, 2022.

We conduct our international operations in jurisdictions that have varying laws and regulations regarding income and other taxes, some of which are subject to different interpretations. We recognize benefit for an uncertain tax position if it is more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the uncertain tax position is then measured and recognized at the largest amount that we believe is greater than 50% likely of being realized upon ultimate settlement.

We have accrued a net total of $29 million and $11 million in other long-term liabilities on our consolidated balance sheet for worldwide unrecognized tax liabilities as of September 30, 2023 and December 31, 2022, respectively. We account for any applicable interest and penalties related to uncertain tax positions as a component of our provision for income taxes in our consolidated financial statements. Changes in our management's judgment related to those liabilities would affect our effective income tax rate in the periods of change.

Our tax returns are subject to audit by taxing authorities in multiple jurisdictions. These audits often take years to complete and settle. The following table lists the earliest tax years open to examination by tax authorities where we have significant operations:

Jurisdiction	Periods
United States	2014
United Kingdom	2020
Norway	2018
Angola	2015
Brazil	2018
Australia	2018

We have ongoing tax audits and judicial tax appeals in various jurisdictions. The outcome of these audits and judicial tax appeals may have an impact on uncertain tax positions for income tax returns subsequently filed in those jurisdictions.

SUBSEQUENT EVENTS

On October 2, 2023, we completed a private placement of $200 million aggregate principal amount of the New 2028 Senior Notes to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act and to non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act. The New 2028 Senior Notes constitute an additional issuance of the Existing 2028 Senior Notes, which we issued in February 2018, in an aggregate principal amount of $300 million, and form a single series with such notes. We will pay interest on the New 2028 Senior Notes on February 1 and August 1 of each year, commencing on February 1, 2024. The New 2028 Senior Notes are scheduled to mature on February 1, 2028. We may redeem some or all of the New 2028 Senior Notes at specified redemption prices. We received net proceeds from the offering of the New 2028 Senior Notes of approximately $180 million after deducting the initial purchasers’ discounts.

On October 2, 2023, we used the net proceeds from the offering discussed above, together with cash on hand, to fund our offer to purchase (the “Tender Offer”) for cash any and all of the $400 million principal amount outstanding of the 2024 Senior Notes. We repurchased $312 million principal amount of the 2024 Senior Notes at par plus accrued and unpaid interest of $5.5 million for approximately $318 million. The consummation of the Tender Offer was contingent upon the completion of the offering discussed above, which was satisfied on October 2, 2023.

On October 2, 2023, we delivered a notice to the holders of the 2024 Senior Notes that we have elected to redeem all of the remaining $88 million principal amount outstanding of the 2024 Senior Notes on the Redemption Date pursuant to our optional redemption right under the indenture governing the 2024 Senior Notes. The redemption price will be equal to 100% of the principal amount of the 2024 Senior Notes plus accrued and unpaid interest up to but not including the Redemption Date plus a “make-whole premium.” We intend to finance the redemption of the 2024 Senior Notes with cash on hand. Upon retirement of the 2024 Senior Notes, we will write off the related unamortized interest rate swaps and debt issuance cost balances.

Summary Of Major Accounting Policies (Policy)

Sep. 30, 2023

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation. Oceaneering International, Inc. (“Oceaneering,” “we” “our” or “us”) has prepared these unaudited consolidated financial statements pursuant to instructions for quarterly reports on Form 10-Q, which we are required to file with the United States Securities and Exchange Commission (the “SEC”). These financial statements do not include all information and footnotes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). These financial statements reflect all adjustments that we believe are necessary to present fairly our financial position as of September 30, 2023, and our results of operations and cash flows for the periods presented. Except as otherwise disclosed herein, all such adjustments are of a normal and recurring nature. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in our annual report on Form 10-K for the year ended December 31, 2022. The results for interim periods are not necessarily indicative of annual results.

Principles of Consolidation

Principles of Consolidation. The consolidated financial statements include the accounts of Oceaneering and our 50% or more owned and controlled subsidiaries. We also consolidate entities that are determined to be variable interest entities if we determine that we are the primary beneficiary; otherwise, we account for those entities using the equity method of accounting. We use the equity method to account for our investments in unconsolidated affiliated companies of which we own an equity interest of between 20% and 50% and as to which we have significant influence, but not control, over operations. We use the cost method for all other long-term investments. Investments in entities that we do not consolidate are reflected on our balance sheet in other noncurrent assets. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use Of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires that our management make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and Cash Equivalents. Cash and cash equivalents include demand deposits and highly liquid investments with original maturities of three months or less from the date of investment.

Inventory

Inventory. Inventory is valued at the lower of cost or net realizable value. We determine cost using the weighted-average method. We periodically review the value of items in inventory and record write-downs or write-offs of inventory based on our assessment of market conditions. Write-downs and write-offs are charged to cost of services and products. We did not record any write-downs or write-offs of inventory in the three- and nine-month periods ended September 30, 2023 and 2022.

Property and Equipment

Goodwill. Our goodwill is evaluated for impairment annually and whenever we identify certain triggering events or circumstances that would more likely than not reduce the fair value of a reporting unit below its carrying amount.

In our annual evaluation of goodwill, we perform a qualitative or quantitative impairment test. Under the qualitative approach, if we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we are required to perform the quantitative analysis to determine the fair value for the reporting unit. We then compare the fair value of the reporting unit with its carrying amount and recognize an impairment loss for the amount by which the carrying amount exceeds the fair value of the reporting unit. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. We also consider income tax effects from any

tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. We did not identify indicators of impairment for goodwill for the three- and nine-month periods ended September 30, 2023 and 2022.

Foreign Currency Translations

Foreign Currency Translation. The functional currency for most of our foreign subsidiaries is the applicable local currency. Results of operations for foreign subsidiaries with functional currencies other than the U.S. dollar are translated into U.S. dollars using average exchange rates during the period. Assets and liabilities of these foreign subsidiaries are translated into U.S. dollars using the exchange rates in effect as of the balance sheet date, and the resulting translation adjustments are recognized, net of tax, in accumulated other comprehensive income (loss) as a component of shareholders' equity. All foreign currency transaction gains and losses are recognized currently in the Consolidated Statements of Operations. We recorded $0.9 million and $(3.6) million of foreign currency transaction gains (losses) in the three- and nine-month periods ended September 30, 2023, respectively. We recorded $(1.1) million and $0.2 million of foreign currency transaction gains (losses) in the three- and nine-month periods ended September 30, 2022, respectively. Those amounts are included as a component of other income (expense), net in our Consolidated Statement of Operations.

Leases

Leases. We determine whether a contract is or contains a lease at inception, whether as a lessee or a lessor. We take into consideration the elements of an identified asset, right to control and the receipt of economic benefit in making those determinations.

As a lessor, we lease certain types of equipment along with the provision of services and utilize the expedient allowing us to combine the lease and non-lease components into a combined component that is accounted for (1) under “Leases” (“ASC 842”), when the lease component is predominant, and (2) under the accounting standard “Revenue from Contracts with Customers” (“ASC 606”), when the service component is predominant. In general, when we have a service component, it is typically the predominant element and leads to accounting under ASC 606.

As a lessor, we lease certain types of equipment, often providing services at the same time. These leases can be priced on a dayrate or lump-sum basis for periods ranging from a few days to multi-year contracts. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our

customer's discretion. These leases generally do not contain options to purchase, material restrictions or covenants that impact our accounting for leases.

As a lessee, we lease land, buildings, vessels and equipment for the operation of our business and to support some of our service line revenue streams. These generally carry lease terms that range from days for operational and support equipment to 15 years for land and buildings. These leases are negotiated on commercial terms at market rates and many carry standard options to extend or terminate at our discretion. When the exercise of those options is reasonably certain, we include them in the lease assessment. Our leases do not contain material restrictions or covenants that impact our accounting for them, nor do we provide residual value guarantees.

As a lessee, we utilize the practical expedients to not recognize leases with an initial lease term of 12 months or less on the balance sheet and to combine lease and non-lease components together and account for the combined component as a lease for all asset classes, except real estate.

Right-of-use operating lease assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement or modification date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate, based on the information available at commencement or modification date in determining the present value of future payments. In determining the incremental borrowing rate, we considered our external credit ratings, bond yields for us and our identified peers, the risk-free rate in geographic regions where we operate, and the impact associated with providing collateral over a similar term as the lease for an amount equal to the future lease payments. Our right-of-use operating lease assets also include any lease prepayments made and exclude lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease. These options are included in the lease term when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

Allowance for Credit Losses Notes (Policies)

Accounting Policies Credit Losses [Abstract]

Allowance for Credit Losses [Text Block]

Allowances for Credit Loss—Financial Assets Measured at Amortized Costs. We identify our allowance for credit losses based on future expected losses when accounts receivable, contract assets or held-to-maturity loan receivables are created rather than when losses are probable.

We use the loss-rate method in developing the allowance for credit losses, which involves identifying pools of assets with similar risk characteristics, reviewing historical losses within the last three years and consideration of reasonable supportable forecasts of economic indicators. Changes in estimates, developing trends and other new information could have material effects on future evaluations.

We monitor the credit quality of our accounts receivable and other financing receivable amounts by frequent customer interaction, following economic and industry trends and reviewing specific customer data. Our other receivable amounts include contract assets and held-to-maturity loans receivable, which we consider to have a low risk of loss.

We consider macroeconomic conditions when assessing our credit risk exposure, including any impacts from the conflicts in Russia and Ukraine and in the Middle East and volatility in the financial services industry and the oil and natural gas markets, and the effects thereof on our customers and various counterparties. We have determined the impacts to our credit loss expenses are de minimis for the three- and nine-month periods ended September 30, 2023 and 2022.

As of September 30, 2023, our allowance for credit losses was $2.1 million for accounts receivable and $0.6 million for other receivables. As of December 31, 2022, our allowance for credit losses was $2.0 million for accounts receivable and $0.3 million for other receivables. Our allowance for credit losses increased in the nine months

ended September 30, 2023, as compared to the same period in the prior year, primarily due to corresponding increases in revenue and accounts receivable.

Financial assets are written off when deemed uncollectible and there is no reasonable expectation of recovering the contractual cash flows. During the three- and nine-month periods ended September 30, 2023, we did not write off any financial assets. In the three months ended September 30, 2023, we received cash proceeds of $1.8 million as partial recovery of a previously written off financial asset.

Accounts receivable are considered to be past due after the end of the contractual terms agreed to with the customer. There were no material past due amounts that we consider uncollectible for our financial assets as of September 30, 2023. We generally do not require collateral from our customers.
