Valaris Reports Fourth Quarter 2023 Results

Hamilton, Bermuda, February 21, 2024… Valaris Limited (NYSE: VAL) ("Valaris" or the "Company") today reported fourth quarter 2023 results.

President and Chief Executive Officer Anton Dibowitz said, “We continue to execute on our operating leverage by repricing rigs from legacy day rates to meaningfully higher market rates and successfully delivering reactivated rigs with attractive contracts. At the same time, we remain laser focused on delivering high levels of operational performance to our customers, as evidenced by another strong year of revenue efficiency.”

Dibowitz added, “During the fourth quarter, we were awarded new contracts and extensions with associated contract backlog of more than $1.4 billion. These awards include two multi-year drillship contracts at leading-edge day rates and several jackup contracts across the North Sea, Australia and Trinidad, demonstrating the depth of our customer relationships, track record of operational delivery and broad-based strength of the market.”

Dibowitz concluded, “We remain confident in the strength and duration of this upcycle and the outlook for Valaris is positive. We expect to deliver significant earnings and cash flow growth over the next few years and we intend to return all future free cash flow to shareholders unless there is a better or more value accretive use for it.”

Financial and Operational Highlights

•Delivered revenue efficiency of 93% during the quarter and 96% for the year;

•VALARIS 110 received TotalEnergies' and North Oil Company's global jackup Rig of the Year award;

•Awarded new contracts and extensions with associated contract backlog of more than $1.4 billion during the fourth quarter;

•Repurchased $50 million of shares during the fourth quarter and $200 million during the year;

•Valaris Board of Directors authorized an increase in the Company's share repurchase program to $600 million from $300 million in February 2024;

Fourth Quarter Review

Net income increased to $829 million from $17 million in the third quarter 2023. Net income for the fourth quarter 2023 included a tax benefit of $790 million discussed below. Adjusted EBITDA increased to $58 million from $40 million in the third quarter primarily due to more operating days across the fleet and lower reactivation expense. Adjusted EBITDAR increased to $96 million from $91 million in the third quarter.

1

Revenues increased to $484 million from $455 million in the third quarter 2023. Excluding reimbursable items, revenues increased to $453 million from $427 million in the third quarter. The increase was primarily due to more operating days across the fleet, including for drillship VALARIS DS-17 that commenced a contract in early September, following its reactivation, and jackup VALARIS 107, which started a contract early in the fourth quarter after being idle for most of the third quarter.

Contract drilling expense increased to $402 million from $391 million in the third quarter 2023. Excluding reimbursable items, contract drilling expense increased to $374 million from $369 million in the third quarter primarily due to the increase in operating days mentioned above. This was partially offset by lower reactivation expense and lower repair and maintenance expense for the jackup fleet.

Depreciation expense increased to $28 million from $26 million in the third quarter 2023. General and administrative expense of $24 million was in line with the third quarter 2023.

Other income decreased to $0 million from $11 million in the third quarter 2023. This was primarily due to foreign currency exchange losses during the quarter compared to gains in the third quarter and an increase in interest expense associated with a $400 million debt issuance that was completed in the third quarter.

Tax benefit was $790 million compared to tax expense of $11 million in the third quarter 2023. The fourth quarter tax provision included $800 million of tax benefit due to changes in deferred tax asset valuation allowances.

Cash and cash equivalents and restricted cash decreased to $636 million as of December 31, 2023, from $1.1 billion as of September 30, 2023. The decrease was primarily due to capital expenditures and share repurchases, partially offset by positive operating cash flow.

Capital expenditures increased to $463 million from $106 million in the third quarter 2023 primarily due to the Company exercising options to take delivery of newbuild drillships VALARIS DS-13 and DS-14 for an aggregate purchase price of $337 million during the quarter.

Fourth Quarter Segment Review

Floaters

Floater revenues increased to $263 million from $243 million in the third quarter 2023. Excluding reimbursable items, revenues increased to $247 million from $232 million in the third quarter. The increase was primarily due to more operating days for VALARIS DS-17, which commenced its contract with Equinor offshore Brazil in early September, following its reactivation. This was partially offset by fewer operating days for VALARIS DS-12 due to mobilization and a brief shipyard visit between contracts.

Contract drilling expense increased to $226 million from $215 million in the third quarter 2023. Excluding reimbursable items, contract drilling expense increased to $211 million from $206 million in the third quarter. The increase was primarily due to more operating days for VALARIS DS-17, partially offset by lower reactivation expense.

Jackups

Jackup revenues increased to $179 million from $166 million in the third quarter 2023. Excluding reimbursable items, revenues increased to $170 million from $155 million in the third quarter primarily due to more operating days for VALARIS 107, 249 and Norway, all of which incurred some idle time during the third quarter. This was partially offset by fewer operating days for VALARIS 76 and 123, both of which completed contracts during the fourth quarter and are undergoing contract preparation and planned maintenance work prior to the start of their next contracts in 2024.

2

Contract drilling expense increased to $123 million from $122 million in the third quarter 2023. Excluding reimbursable items, contract drilling expense increased to $115 million from $114 million in the third quarter. Contract drilling expense was largely flat on higher revenues primarily due to lower repair and maintenance expense.

ARO Drilling

Revenues increased to $134 million from $122 million in the third quarter 2023 primarily due to newbuild jackup Kingdom 1 commencing its maiden contract in November and more operating days for ARO 4001 following some out of service days for planned maintenance during the third quarter. Contract drilling expense decreased to $88 million from $92 million in the third quarter primarily due to lower bareboat charter expense, partially offset by more operating days for the owned fleet.

Other

Revenues decreased to $41 million from $46 million in the third quarter 2023 primarily due to lower revenues earned from bareboat charter agreements with ARO. Contract drilling expense decreased to $18 million from $19 million in the third quarter.

(1)Our contract drilling backlog reflects commitments, represented by signed drilling contracts, and is calculated by multiplying the contracted day rate by the contract period. Contract drilling backlog includes drilling contracts subject to FID and drilling contracts which grant the customer termination rights if FID is not received with respect to projects for which the drilling rig is contracted. The contracted day rate excludes certain types of lump sum fees for rig mobilization, demobilization, contract preparation, as well as customer reimbursables and bonus opportunities.

(1)Average daily revenue is derived by dividing contract drilling revenues, adjusted to exclude certain types of non-recurring reimbursable revenues, revenues earned during suspension periods and revenues attributable to amortization of drilling contract intangibles, by the aggregate number of operating days. Beginning with the third quarter of 2023, we began presenting average daily revenue instead of the previously reported average day rate metric, which further excluded lump-sum revenues and amortization thereof. Average daily revenue is a more comprehensive measurement of our revenue-earning performance and more closely aligns with the calculation methodology used by our closest offshore drilling peers. The prior period has been adjusted to conform with the current period presentation.

(1)Average daily revenue is derived by dividing contract drilling revenues, adjusted to exclude certain types of non-recurring reimbursable revenues, revenues earned during suspension periods and revenues attributable to amortization of drilling contract intangibles, by the aggregate number of operating days.

(2)All ARO leased rigs are leased from Valaris.

(3)Rig utilization is derived by dividing the number of operating days by the number of available days in the period for the rig fleet.

(4)Revenue efficiency is day rate revenue earned as a percentage of maximum potential day rate revenue.

(5)Rig count for owned rigs as of December 31, 2023 excludes a rig under construction, which is expected to be delivered in the first half of 2024.

(6)Represents the maximum number of days available in the period for the rig fleet, calculated by multiplying the number of rigs in each asset category by the number of days in the period, irrespective of asset status.

(7)Represents the total number of days under contract in the period. Days under contract equals the total number of days that rigs have earned and recognized day rate revenue, including days associated with early contract terminations, compensated downtime and mobilizations. When revenue is deferred and amortized over a future period, for example when we receive fees while mobilizing to commence a new contract or while being upgraded in a shipyard, the related days are excluded from days under contract.

Non-GAAP Financial Measures

To supplement Valaris’ condensed consolidated financial statements presented on a GAAP basis, this press release provides investors with Adjusted EBITDA and Adjusted EBITDAR, which are non-GAAP measures.

Valaris defines "Adjusted EBITDA" as net income (loss) from continuing operations before income tax expense, interest expense, other (income) expense, depreciation expense, amortization, loss on impairment and equity in (earnings) losses of ARO. Adjusted EBITDA is a non-GAAP measure that our management uses to facilitate period-to-period comparisons of our core operating performance and to evaluate our long-term financial performance against that of our peers. We believe that this measure is useful to investors and analysts in allowing for greater transparency of our core operating performance and makes it easier to compare our results with those of other companies within our industry. Adjusted EBITDA should not be considered (a) in isolation of, or as a substitute for, net income (loss), (b) as an indication of cash flows from operating activities, or (c) as a measure of liquidity. Adjusted EBITDA may not be comparable to other similarly titled measures reported by other companies.

Valaris defines "Adjusted EBITDAR" as Adjusted EBITDA before reactivation costs. Adjusted EBITDAR is a non-GAAP measure that our management uses to assess the performance of our fleet excluding one-time rig reactivation costs. We believe that this measure is useful to investors and analysts in allowing for greater transparency of our core operating performance. Adjusted EBITDAR should not be considered (a) in isolation of, or as a substitute for, net income (loss), (b) as an indication of cash flows from operating activities, or (c) as a measure of liquidity. Adjusted EBITDAR may not be comparable to other similarly titled measures reported by other companies.

Valaris defines ARO "EBITDA" as net income before income tax expense, other expense, net and depreciation expense. EBITDA is a non-GAAP measure that our management uses to facilitate period-to-period comparisons of ARO's core operating performance and to evaluate ARO's long-term financial performance against that of ARO's peers. We believe that this measure is useful to investors and analysts in allowing for greater transparency of ARO's core operating performance and makes it easier to compare ARO's results with those of other companies within ARO's industry. EBITDA should not be considered (a) in isolation of, or as a substitute for, net income (loss), (b) as an indication of cash flows from operating activities, or (c) as a measure of liquidity. EBITDA may not be comparable to other similarly titled measures reported by other companies.

The Company is not able to provide a reconciliation of the Company's forward-looking Adjusted EBITDA, as discussed on its fourth quarter 2023 earnings conference call, to the most directly comparable GAAP measure without unreasonable effort because of the inherent difficulty in forecasting and quantifying certain amounts necessary for such a reconciliation, including forward-looking tax expense and other income (expense).

Non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures prepared in accordance with GAAP.
