NABORS INDUSTRIES LTD

Previous wording

The demand for our services and products is a function of the level of spending by oil and gas companies for exploration, development and production activities. The level of exploration, development and production activities is to a large extent tied to the prices of oil and natural gas, which can fluctuate significantly, are highly volatile and tend to be highly sensitive to supply and demand cycles. Additionally, some oil and gas companies may intentionally limit their capital spending to a percentage of their operating cash flows.

Current wording

The demand for our services and products is a function of spending by oil and gas companies for exploration, development and production activities. The level of exploration, development and production activities is to a large extent tied to the prices of oil and natural gas, which can fluctuate significantly, are highly volatile and tend to be highly sensitive to factors including supply and demand cycles and geopolitical uncertainties, particularly those impacting large hydrocarbon-producing countries. Certain oil and gas companies may also intentionally limit their capital spending as they focus on generating returns to shareholders as opposed to maximizing hydrocarbon production. Additionally, there has recently been an increasing number of customer consolidations within the industry especially in the United States. In some cases, these transactions may have an impact on overall rig demand, as the acquiring company may apply criteria that results in a different level of demand for drilling rigs than the previous two companies would have had on a stand-alone basis.

Previous wording

Since late 2022 and through 2023, global energy commodity markets have experienced high levels of volatility. In the U.S., operators generally reacted to this market by reducing their drilling activity. Recent production actions announced by certain large international oil producers have been supportive of both oil prices and oil-focused activity broadly, especially in international markets. Natural gas prices, particularly in the United States, declined significantly through 2023.

Current wording

Since late 2022 and continuing through the fourth quarter of 2024, global energy commodity markets have experienced high levels of volatility. In the U.S., operators generally reacted to these market conditions by reducing their drilling activity. Recent production actions announced by certain large international oil producers have been supportive of both oil prices and oil-focused activity broadly, especially in international markets. Natural gas prices, particularly in the United States, declined significantly through 2023 and into 2024, to levels which largely persisted into the fourth quarter of 2024 and which have caused operators to reduce natural gas directed activity.

Previous wording

Coming into 2023 economic sentiment was overshadowed by a pervasive concern that a global recession would take hold. The U.S. Federal Reserve’s tightening of interest rates reduced capital availability in the U.S energy market. Rig counts in the U.S. Lower 48 continued to decline throughout the year. Despite the reduction in rig count, rig pricing discipline remained intact.

Current wording

In early 2023 economic sentiment was overshadowed by a pervasive concern that a global recession would take hold. The U.S. Federal Reserve’s tightening of interest rates reduced capital availability in the U.S energy market. As these higher interest rates continued, rig counts in the U.S. Lower 48 continued to decline throughout the year. More recently, the U.S. Federal Reserve reduced interest rates. The impact of that decision should become evident in the coming quarters. Despite the reduction in rig count, rig pricing discipline remained intact, generally supportive of rig dayrates and daily rig margins.

Previous wording

Entering 2024 U.S. oil and gas production has proved resilient in the face of reduced drilling activity. Internationally, we see the expansion of production capacity as well as the widespread development of unconventional resources driving an expected increase in oilfield activity across those markets.

The decrease in net loss is attributable to improved market conditions, which has resulted in an increase of approximately $239.3 million in adjusted operating income across all of our segments from the prior year. In addition, gains related to mark-to-market activity for the common share warrants during 2023 contributed approximately $153.8 million to the decrease in net loss along with approximately $20.7 million in gains related to debt repurchases. These gains were offset by an increase of $30.6 million in foreign currency losses. See Other Financial Information —Other, net below for additional discussion.

Adjusted operating income (loss) across our operating segments, declined by $16.9 million, or 2%. A decline in U.S. activity was largely offset by increased activity in international markets, benefiting both our International Drilling and Drilling Solutions segments. Approximately $78.0 million of the increase in net loss is attributable to lower mark-to-market gains related to the common share warrants, which decreased from $54.7 million in 2023 to $16.9 million in 2024, and the impact from gains or losses from debt repurchases, which resulted in a gain of $25.3 million in 2023 and losses of $14.9 million in 2024. In addition, interest expense increased by approximately $25.6 million due to increasing interest rates.

These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the balance sheet date and the amounts of revenues and expenses recognized during the reporting period. We analyze our estimates based on our historical experience and various other assumptions that we believe to be reasonable under the circumstances. However, actual results could differ from our estimates. The following is a discussion of our critical accounting estimates. Management considers an accounting estimate to be critical if:

Depreciation of Property, Plant and Equipment. The drilling and drilling services industries are very capital intensive. Property, plant and equipment represented 55% of our total assets as of December 31, 2023, and depreciation and amortization constituted 22% of our total costs and other deductions in 2023.

Impairment of Long-Lived Assets. As discussed above, the drilling and drilling services industries are very capital intensive. We review our assets for impairment when events or changes in circumstances indicate that their carrying amounts may not be recoverable. If the estimated undiscounted future cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to the extent the carrying amount of the long-lived asset exceeds its estimated fair value determined utilizing either a discounted cash flows or market approach model. Management considers a number of factors such as estimated future cash flows from the assets, appraisals and current market value analysis in determining fair value. The determination of future cash flows requires the estimation of utilization, dayrates, operating margins, sustaining capital and remaining economic life. Such estimates can change based on market conditions, technological advances in the industry or changes in regulations governing the industry. The appraisals require estimation based on location, working status, asset condition and market conditions. Significant and unanticipated changes to the assumptions could result in future impairments. A significantly prolonged period of lower oil and natural gas prices could continue to adversely affect the demand for and prices of our services, which could result in future impairment charges. As the determination of whether impairment charges should be recorded on our long-lived assets is subject to significant management judgment, and an impairment of these assets could result in a
