Valaris Reports Third Quarter 2023 Results

Hamilton, Bermuda, November 6, 2023… Valaris Limited (NYSE: VAL) ("Valaris" or the "Company") today reported third quarter 2023 results.

President and Chief Executive Officer Anton Dibowitz said, “We are pleased that VALARIS DS-17 commenced its contract offshore Brazil during the quarter and expect that it will contribute meaningful earnings and cash flow going forward. While our floater revenue efficiency for the quarter was below our expectations, our year to date fleetwide revenue efficiency remains strong at 97%, and we remain committed to delivering safe and efficient operations.”

Dibowitz added, “During the third quarter, we were awarded new contracts and extensions with associated contract backlog of approximately $465 million. Our long-term contract for VALARIS DS-7 was the seventh contract awarded to our previously stacked floaters since mid-2021. Following this reactivation we will have 10 drillships working and will remain disciplined in exercising our operational leverage with only one stacked drillship and two newbuild drillship options remaining.”

Dibowitz concluded, “The outlook for Valaris is positive, with increasing demand and constrained supply tightening the market. We are confident in the strength and duration of this upcycle, and we expect to deliver meaningfully improved earnings in both 2024 and 2025 due to the impact of recent and ongoing drillship reactivations at attractive day rates, as well as the repricing of rigs from legacy day rate contracts to higher markets rates.”

Financial and Operational Highlights

•Net income of $17 million, Adjusted EBITDA of $40 million and Adjusted EBITDAR of $91 million;

•Delivered revenue efficiency of 94% during the quarter and 97% year to date;

•Recognized by the Center for Offshore Safety with its 2023 Safety Leadership Award for the Valaris Basic Training program;

•Awarded new contracts and extensions with associated contract backlog of approximately $465 million during the third quarter;

•Additional new contracts and extensions awarded following quarter end, with associated contract backlog of approximately $335 million;

•Executed $400 million add-on to Senior Secured Second Lien Notes to finance expected exercise of purchase options for newbuild drillships VALARIS DS-13 and DS-14;

•Repurchased $85 million of shares during the third quarter and $171 million to date;

•Remain on track to deliver on our 2023 share repurchase target of $200 million;

•ARO Drilling secured attractive financing for newbuild jackups Kingdom 1 and 2.

Third Quarter Review

Net income was $17 million compared to net loss of $27 million in the second quarter 2023. Adjusted EBITDA increased to $40 million from $15 million in the second quarter primarily due to two jackups and one floater commencing contracts during the quarter after not working in the second quarter, as well as an increase in average daily revenue for both the floater and jackup fleets. These items were partially offset by higher reactivation expense and an increase in unplanned downtime related to several floaters. Adjusted EBITDAR increased to $91 million from $59 million in the second quarter.

1

Revenues increased to $455 million from $415 million in the second quarter 2023. Excluding reimbursable items, revenues increased to $427 million from $388 million in the second quarter. The increase was primarily due to two jackups and one floater commencing contracts during the quarter after not working in the second quarter, as well as an increase in average daily revenue for both the floater and jackup fleets. These items were partially offset by an increase in unplanned downtime related to several floaters.

Contract drilling expense increased to $391 million from $374 million in the second quarter 2023. Excluding reimbursable items, contract drilling expense increased to $369 million from $348 million in the second quarter. The increase was primarily due to higher reactivation expense and higher operating costs resulting from the contract startups mentioned above.

Depreciation expense increased to $26 million from $25 million in the second quarter 2023. General and administrative expense decreased to $24 million from $26 million in the second quarter 2023.

Other income increased to $11 million from $7 million in the second quarter 2023. This was primarily due to foreign currency exchange gains during the quarter compared to losses in the second quarter.

Tax expense decreased to $11 million from $25 million in the second quarter 2023. The third quarter tax provision included $2 million of discrete tax benefit, which was primarily attributable to the resolution of prior period tax matters, partially offset by changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years. The second quarter tax provision included $6 million of discrete tax expense, which was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years. Adjusted for discrete items, tax expense decreased to $13 million from $18 million in the second quarter primarily due to a reduction in deferred tax asset valuation allowances.

Cash and cash equivalents and restricted cash increased to $1.1 billion as of September 30, 2023, from $805 million as of June 30, 2023. The increase was primarily due to the issuance of $400 million of additional 8.375% Senior Secured Second Lien Notes due 2030, partially offset by capital expenditures and share repurchases. The net proceeds from this issuance are intended to fund the purchase of drillships VALARIS DS-13 and DS-14, and for general corporate purposes.

Capital expenditures increased to $106 million from $71 million in the second quarter 2023 primarily due to an increase in reactivation and customer-specific capital expenditures associated with VALARIS DS-17, DS-8 and DS-7.

Third Quarter Segment Review

Floaters

Floater revenues increased to $243 million from $227 million in the second quarter 2023. Excluding reimbursable items, revenues increased to $232 million from $216 million in the second quarter. The increase was primarily due to VALARIS DS-17 commencing its contract with Equinor offshore Brazil in early September, following its reactivation, as well as an increase in average daily revenue for the rest of the floater fleet during the third quarter. These benefits were partially offset by fewer operating days for several floaters primarily due to unplanned downtime events.

Contract drilling expense increased to $215 million from $196 million in the second quarter 2023. Excluding reimbursable items, contract drilling expense increased to $206 million from $185 million in the second quarter. The increase was primarily due to higher reactivation expense associated with VALARIS DS-7 following a contract award in July for which the rig is being reactivated and VALARIS DS-17 commencing a contract in early September.

2

Jackups

Jackup revenues increased to $166 million from $145 million in the second quarter 2023. Excluding reimbursable items, revenues increased to $155 million from $135 million in the second quarter primarily due to more operating days and an increase in average daily revenue. Revenues from the jackup fleet benefited from contract startups for VALARIS 121 and 249, as well as several rigs commencing new contracts at higher day rates.

Contract drilling expense decreased to $122 million from $124 million in the second quarter 2023. Excluding reimbursable items, contract drilling expense of $114 million was in line with the second quarter. Lower repair and maintenance costs across the fleet and lower costs resulting from the sale of VALARIS 54 were offset by higher operating costs for VALARIS 249, which commenced a contract offshore Trinidad during the quarter after mobilizing from New Zealand during the second quarter.

ARO Drilling

Revenues increased to $122 million from $118 million in the second quarter 2023 primarily due to more operating days resulting from less out of service time for planned maintenance during the third quarter. Contract drilling expense decreased to $92 million from $95 million in the second quarter primarily due to lower repair costs associated with the previously mentioned planned maintenance.

Other

Revenues increased to $46 million from $43 million in the second quarter 2023 and contract drilling expense increased to $19 million from $18 million in the second quarter.

Third Quarter Results Versus Guidance

The Company's third quarter 2023 results were lower than prior guidance primarily due to lower than expected floater revenue efficiency and two contract commencement delays.

(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. Prior periods were 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 excludes two rigs under construction, the first of which was delivered in October 2023 and the second is expected to be delivered in the first quarter 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.

In the second quarter 2023, Valaris changed its Adjusted EBITDA and Adjusted EBITDAR calculations to include amortization associated with deferred mobilization and contract preparation revenues and costs and deferred capital upgrade revenues to better reflect the earnings profile of our operations and more closely align with the calculation methodology used by Valaris' closest offshore drilling peers. Adjusted EBITDA and Adjusted EBITDAR for all comparative periods have been revised using the new methodology to consistently reflect this change.

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 third 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.
