Nabors Announces Second Quarter 2025 Results

HAMILTON, Bermuda, July 29, 2025 /PRNewswire/ - Nabors Industries Ltd. (“Nabors” or the “Company”) (NYSE: NBR) today reported second quarter 2025 operating revenues of $833 million, compared to operating revenues of $736 million in the first quarter. Net loss attributable to Nabors shareholders for the quarter was $31 million, compared to net income of $33 million in the first quarter. This equates to a loss per diluted share of $2.71, compared to earnings per diluted share of $2.18 in the first quarter. The first quarter included a one-time, non-cash net gain on the Parker transaction of $113.0 million, or $9.68 per diluted share. Second-quarter adjusted EBITDA was $248 million, compared to $206 million in the previous quarter.

2Q 2025 Highlights

| o | The SANAD drilling joint venture with Saudi Aramco deployed two newbuild rigs in the Kingdom. These bring the total number of deployments to twelve. Two more units are scheduled to start operations over the balance of this year.

| o | Saudi Aramco awarded the fourth tranche of newbuilds to SANAD. This award of five rigs marks the next step in SANAD’s 50-rig newbuild program. The first rigs of this tranche are scheduled to commence operating in 2026, with the final one in 2027.

| o | Several impactful international rig reactivations were completed in Kuwait. All three previously announced awards have commenced operations, one of which began in early July. These high-specification rigs are working under multiyear contracts and are expected to contribute materially to the International Drilling segment earnings during the second half of 2025 and beyond.

| o | Nabors’ high-specification PACE® series SmartRigs® set several milestones extending lateral wellbore lengths.

| o | In the Bakken, a PACE®-X rig followed up drilling an operator’s first four-mile lateral in the formation with two more four-mile lateral wells.

| o | Also in the Bakken, another operator utilizing a PACE®-B rig drilled back-to-back four-mile lateral wells.

| o | In the Haynesville a PACE®-X rig drilled the basin’s longest lateral at 20,000 feet; the well reached a total depth of 32,000 feet.

| o | In the Eagle Ford, a PACE®-M rig drilled a record well in the basin, at 32,525 feet, including a 22,500-foot lateral section.

| o | Significant progress was made on the integration of the Parker Wellbore businesses acquired in March. These contributed materially to Nabors financial results in the second quarter. Cost synergies realized during the quarter support the $40 million previously targeted for 2025.

Anthony G. Petrello, Nabors Chairman, CEO and President, commented, “Our second quarter results demonstrated the strength of the Nabors portfolio while reflecting a full quarter contribution from the acquisition of Parker Wellbore. In total, EBITDA from the legacy Nabors businesses increased sequentially. I am pleased with the performance of the Parker operations, and our progress to realize expected cost synergies.

“Recent deployments of high-spec rigs in the Middle East along with those scheduled over the balance of 2025 should drive growth in our International Drilling segment. The SANAD newbuild program is a key element of our future value creation. The award of the fourth five-rig tranche cements SANAD’s growth prospects into 2027.

“Before the impact from Parker, adjusted EBITDA grew sequentially in all three of the business lines in our U.S. Drilling segment. The Lower-48 rig market in oil focused basins remains flat to down, and we are working to mitigate the impact of the current industry rig count and dayrates. At the same time, natural gas drilling has moved upwards. We see our rig count and leading-edge pricing stabilizing in the third quarter and through the end of the year.

“Our U.S. Offshore and Alaska operations are performing well. Including the contributions of Parker, these two businesses comprise a growing portion of our overall U.S. Drilling segment. In particular, our Alaska fleet is poised to capitalize on growth in that market.

“With the addition of Parker’s operations, Nabors Drilling Solutions now comprises over 25% of adjusted EBITDA from our operating segments. The Parker product lines in NDS – the largest being Quail Tools – outperformed our expectations in the second quarter. These results highlight the potential that led us to the acquisition.”

Segment Results

International Drilling adjusted EBITDA totaled $117.7 million, compared to $115.5 million in the first quarter. Average rig count increased by one, primarily reflecting the startup of newbuild rigs in Saudi Arabia and Kuwait, offset by the conclusion of contracts for a rig each in Papua New Guinea and Mexico. Daily adjusted gross margin for the second quarter improved to $17,534, driven primarily by the high-margin additions.

The U.S. Drilling segment reported second quarter adjusted EBITDA of $101.8 million, compared to $92.7 million in the previous quarter. All three of the U.S. Drilling segment’s operations drove this improvement. In the Lower 48, the higher rig count more than offset a decline in daily margins. Improvements in Nabors legacy Alaska and Offshore were augmented by the contribution of a full quarter of the corresponding Parker operations.

Drilling Solutions adjusted EBITDA was $76.5 million, compared to $40.9 million in the first quarter. The legacy Nabors business was down slightly, while the addition of Parker accounted for the sequential increase. This segment’s gross margin, at 53%, improved moderately.

Rig Technologies adjusted EBITDA was $5.2 million, compared to $5.6 million in the prior quarter. A decline in capital equipment deliveries, primarily in the Middle East, contributed to the sequential decrease in adjusted EBITDA.

Adjusted Free Cash Flow

In the second quarter, consolidated adjusted free cash flow was $41 million. This compares to free cash consumption of $61 million in the prior quarter. These figures exclude transaction costs related to the acquisition of Parker Wellbore. Lower quarterly cash interest payments and improved collections from customers contributed to the improved adjusted free cash flow in the second quarter, even as capital expenditures increased. Although receivable collections during the second quarter from Nabors’ main customer in Mexico were significantly lower than expected, the company benefited from higher payments from other clients. The recently announced a $7 - $10 billion capital raise sponsored by the Mexico government is intended to address the issue of overdue vendor liabilities.

William Restrepo, Nabors CFO, stated, “The current economic backdrop appears to be stabilizing, as markets digest recent developments on foreign trade, Federal Reserve policy, and geopolitical conflicts. Favorable trends in employment and inflation indicate a relatively constructive environment, for both our potential capital markets activities and our global operations. These factors have already had a positive impact on credit spreads. Interest rate actions by the Fed and a further narrowing of spreads later this year should benefit us, as we look to refinance our senior notes.

“Our results for the second quarter were solid. In addition to the higher adjusted EBITDA contribution from Parker Wellbore, our legacy drilling rig business improved. Legacy Drilling Solutions and Rig Technologies declined slightly.

“We are encouraged by our relatively stable Lower 48 rig count as we enter the second half and expect our rig count to continue at approximately its current level through year end. This outlook assumes some continued weakness in oil-focused activity, offset by anticipated strength in natural gas drilling. At the same time, our leading-edge daily revenue has remained resilient in the low $30,000 range, providing support to our daily gross margin. This environment gives us confidence about our expected pace of cash flow generation and debt reduction during the balance of 2025.

“Adjusted free cash flow generated by our operations of $41 million in the second quarter improved by more than $100 million as compared to the first quarter. In the third quarter, we expect progress on our collections in Mexico. Assuming these materialize, we forecast similar adjusted free cash flow in the third quarter and anticipate reaching our $80 million target for the full year.

“Parker Wellbore has exceeded our expectations as it grew sequentially on a comparable basis. Margins were high and cash flow generation was better than anticipated. In addition, our synergy capture post-closing has exceeded our targets.”

| o | Daily adjusted gross margin of approximately $17,900

Drilling Solutions

| o | Adjusted EBITDA approximately in line with the second quarter

Rig Technologies

| o | Adjusted EBITDA up approximately $2 - $3 million from the second quarter

Capital Expenditures

| o | Capital expenditures of $200 - $210 million, including $110 - $115 million for the newbuilds in Saudi Arabia

| o | Full-year capital expenditures of $700 - $710 million, with $300 million for the SANAD newbuilds and $60 million for Parker Wellbore

Adjusted Free Cash Flow

| o | Adjusted free cash flow should be in line with the second quarter

Mr. Petrello concluded, “Challenge and change are constants in the oilfield services business. The current environment is no exception. Our strategy to diversify by service line and by geography continues to position Nabors for success throughout the cycle. The Parker business adds key complementary elements to our portfolio.

“With the award of another tranche of newbuild rigs, the outlook for significant free cash flow at SANAD is solidified. We are confident this growth in SANAD will drive significant value creation.”

Forward-looking Statements

The information included in this press release includes forward-looking statements within the meaning of the Securities Act of 1933 and the Securities Exchange Act of 1934. Such forward-looking statements are subject to a number of risks and uncertainties, as disclosed by Nabors from time to time in its filings with the Securities and Exchange Commission. As a result of these factors, Nabors' actual results may differ materially from those indicated or implied by such forward-looking statements. The forward-looking statements contained in this press release reflect management's estimates and beliefs as of the date of this press release. Nabors does not undertake to update these forward-looking statements.

Non-GAAP Disclaimer

This press release presents certain “non-GAAP” financial measures. The components of these non-GAAP measures are computed by using amounts that are determined in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Adjusted operating income (loss) represents income (loss) from continuing operations before income taxes, interest expense, investment income (loss), gain on bargain purchase, and other, net. Adjusted EBITDA is computed similarly, but also excludes depreciation and amortization expenses. In addition, adjusted EBITDA and adjusted operating income (loss) exclude certain cash expenses that the Company is obligated to make. Net debt is calculated as total debt minus the sum of cash, cash equivalents and short-term investments.

Adjusted free cash flow represents net cash provided by operating activities less cash used for capital expenditures, net of proceeds from sales of assets, and before cash paid for acquisition-related costs. Management believes that adjusted free cash flow is an important liquidity measure for the company and that it is useful to investors and management as a measure of the company’s ability to generate cash flow, after reinvesting in the company for future growth, that could be available for paying down debt or other financing cash flows, such as dividends to shareholders. Adjusted free cash flow does not represent the residual cash flow available for discretionary expenditures. Adjusted free cash flow is a non-GAAP financial measure that should be considered in addition to, not as a substitute for or superior to, cash flow from operations reported in accordance with GAAP.

5

| NEWS RELEASE

Each of these non-GAAP measures has limitations and therefore should not be used in isolation or as a substitute for the amounts reported in accordance with GAAP. However, management evaluates the performance of its operating segments and the consolidated Company based on several criteria, including Adjusted EBITDA, adjusted operating income (loss), net debt, and adjusted free cash flow, because it believes that these financial measures accurately reflect the Company’s ongoing profitability, performance and liquidity. Securities analysts and investors also use these measures as some of the metrics on which they analyze the Company’s performance. Other companies in this industry may compute these measures differently. Reconciliations of consolidated adjusted EBITDA and adjusted operating income (loss) to income (loss) from continuing operations before income taxes, net debt to total debt, and adjusted free cash flow to net cash provided by operations, which are their nearest comparable GAAP financial measures, are included in the tables at the end of this press release. We do not provide a forward-looking reconciliation of our outlook for Segment Adjusted EBITDA, Segment Gross Margin or Adjusted Free Cash Flow, as the amount and significance of items required to develop meaningful comparable GAAP financial measures cannot be estimated at this time without unreasonable efforts. These special items could be meaningful.

(1) | Includes our oilfield equipment manufacturing activities.
(2) | Represents the elimination of inter-segment transactions related to our Rig Technologies operating segment.

(3) | Adjusted EBITDA represents net income (loss) before income tax expense (benefit), investment income (loss), interest expense, gain on bargain purchase, other, net and depreciation and amortization. Adjusted EBITDA is a non-GAAP financial measure and should not be used in isolation or as a substitute for the amounts reported in accordance with GAAP. In addition, adjusted EBITDA excludes certain cash expenses that the Company is obligated to make. However, management evaluates the performance of its operating segments and the consolidated Company based on several criteria, including adjusted EBITDA and adjusted operating income (loss), because it believes that these financial measures accurately reflect the Company’s ongoing profitability and performance. Securities analysts and investors use this measure as one of the metrics on which they analyze the Company’s performance. Other companies in this industry may compute these measures differently. A reconciliation of this non-GAAP measure to net income (loss), which is the most closely comparable GAAP measure, is provided in the table set forth immediately following the heading "Reconciliation of Non-GAAP Financial Measures to Net Income (Loss)".
(4) | Represents the elimination of inter-segment transactions and unallocated corporate expenses.
(5) | Adjusted operating income (loss) represents net income (loss) before income tax expense (benefit), investment income (loss), interest expense, gain on bargain purchase and other, net. Adjusted operating income (loss) is a non-GAAP financial measure and should not be used in isolation or as a substitute for the amounts reported in accordance with GAAP.

(6) | Rig revenue days represents the number of days the Company's rigs are contracted and performing under a contract during the period. These would typically include days in which operating, standby and move revenue is earned.
(7) | Average rigs working represents a measure of the average number of rigs operating during a given period. For example, one rig operating 45 days during a quarter represents approximately 0.5 average rigs working for the quarter. On an annual period, one rig operating 182.5 days represents approximately 0.5 average rigs working for the year. Average rigs working can also be calculated as rig revenue days during the period divided by the number of calendar days in the period.
(8) | Daily rig revenue represents operating revenue, divided by the total number of revenue days during the quarter.
(9) | Daily adjusted gross margin represents operating revenue less direct costs, divided by the total number of rig revenue days during the quarter.
(10) | The U.S. Drilling segment includes the Lower 48, Alaska, and Gulf of Mexico operating areas.

(1) Adjusted operating income (loss) represents net income (loss) before income tax expense (benefit), investment income (loss), interest expense, gain on bargain purchase and other, net. Adjusted operating income (loss) is a non-GAAP financial measure and should not be used in isolation or as a substitute for the amounts reported in accordance with GAAP. In addition, adjusted operating income (loss) excludes certain cash expenses that the Company is obligated to make. However, management evaluates the performance of its operating segments and the consolidated Company based on several criteria, including adjusted EBITDA and adjusted operating income (loss), because it believes that these financial measures accurately reflect the Company’s ongoing profitability and performance. Securities analysts and investors use this measure as one of the metrics on which they analyze the Company’s performance. Other companies in this industry may compute these measures differently.

Adjusted free cash flow represents net cash provided by operating activities less cash used for capital expenditures, net of proceeds from sales of assets, and before cash paid for acquisition related costs. Management believes that adjusted free cash flow is an important liquidity measure for the company and that it is useful to investors and management as a measure of the company’s ability to generate cash flow, after reinvesting in the company for future growth, that could be available for paying down debt or other financing cash flows, such as dividends to shareholders. Adjusted free cash flow does not represent the residual cash flow available for discretionary expenditures. Adjusted free cash flow is a non-GAAP financial measure that should be considered in addition to, not as a substitute for or superior to, cash flow from operations reported in accordance with GAAP.
