History
Nabors grew through acquisitions and a completion-services merger, repeatedly refinanced its debt, shrank its share count in 2020, and by late 2025 had absorbed Parker Drilling and sold Quail Tools.
2010-2012: Buying Superior Well Services
In August 2010 Nabors agreed to buy Superior Well Services for $22.12 a share in cash, a deal valued at about $681.5 million. Holders of about 34% of Superior's stock agreed to tender. Nabors planned to pay from cash, new notes and a $700 million four-year revolving credit facility, which it signed on September 7. The antitrust waiting period expired on August 30, and the offer closed with about 92.4% of shares tendered. A short-form merger took effect on September 10, making Superior a wholly owned subsidiary at a total cost of $681,275,030. On September 14 Nabors closed $700 million of 5.0% notes due 2020, with net proceeds of about $692 million.
In 2011 it added a $550 million revolver in April and $700 million of 4.625% notes due 2021 in August. In July 2012 it adopted a shareholder rights plan, which triggers if anyone acquires 10% or more of the shares. In November 2012 it replaced its two revolvers with a $1.5 billion five-year facility.
2013-2015: Dividend, refinancing and the C&J merger
Nabors declared its first quarterly dividend, $0.04 a share, in February 2013. In July it extended the rights plan to July 2016. In September it sold $700 million of new notes and bought back about $785.4 million of its 9.25% notes due 2019, paying $992.1 million.
In June 2014 Nabors agreed to combine its U.S. and Canadian completion and production services businesses with C&J Energy Services. In February 2015 the terms were cut: cash to Nabors fell from about $938 million to about $688 million, and Nabors took a $300 million term loan. The merger closed on March 24, 2015. Nabors received about $688 million in cash and owned about 53% of the combined company, renamed C&J Energy Services Ltd. In July 2015 it enlarged its revolver to $2.2 billion, maturing in 2020. The share count rose in 2015 and fell back by 2016, but the beats do not explain either move.
2016-2017: Aramco joint venture and Tesco
In October 2016 Nabors agreed a 50/50 joint venture with Saudi Aramco to run onshore drilling rigs in Saudi Arabia. Nabors was to contribute $20 million in cash plus rigs, and each side's initial investment through January 2019 was expected to approach $500 million. In December it sold $600 million of 5.5% notes due 2023. In January 2017 it sold $575 million of 0.75% exchangeable notes due 2024, with capped calls to limit dilution.
In August 2017 Nabors agreed to buy Tesco in an all-stock deal at 0.68 of a Nabors share per Tesco share. It closed on December 15, with about 32.0 million new Nabors shares issued.
2018-2020: Equity raising and a debt squeeze
In January 2018 Nabors priced $800 million of 5.75% notes due 2025. In May it raised $521.25 million by selling 35 million shares at $7.75 and 5 million mandatory convertible preferred shares at $50. In October it closed a new $1.267 billion revolver. In December 2019 lenders cut their commitments and the covenant was reset to a limit of 5.5 times EBITDA.
In January 2020 Nabors sold $600 million of 7.25% notes due 2026 and $400 million of 7.50% notes due 2028, and used the money to buy back older, lower-rate notes, accepting about $953 million of them. In September 2020 lenders gained a first claim on certain rigs, with a $160 million minimum liquidity test replacing the debt-to-EBITDA test. In October and December Nabors swapped older notes for new 6.5% and 9.0% notes due 2025, with no cash raised. The year-end share count fell from 363,415,783 in 2019 to 7,294,015 in 2020. The beats do not explain this, though it is consistent with a share consolidation.
2021-2024: Warrants, refinancing and the Parker deal
In June 2021 Nabors issued warrants of two-fifths of a warrant per share, each allowing the purchase of one share at $166.66667 until June 11, 2026. It also agreed to sell its Canadian drilling rigs to Ensign for CAD $117.5 million, though the beats do not confirm that this closed. In November 2021 it sold $700 million of 7.375% notes due 2027. In January 2022 it signed a $350 million secured revolver.
In February 2023 it raised $250 million of 1.750% exchangeable notes due 2029, exchangeable at about $212.51 a share, to redeem its 9.00% notes. In November 2023 it sold $650 million of 9.125% notes due 2030 to retire its 5.75% notes due 2025. In June 2024 it signed a $475 million secured credit facility maturing in 2029. In July it sold $550 million of 8.875% notes due 2031 to redeem the 7.25% notes due 2026.
In October 2024 Nabors agreed to buy Parker Drilling for up to 4,800,000 new Nabors shares, which would give Parker holders about 31% of the combined company.
2025-2026: Parker, Quail Tools and refinancing
The Parker merger closed on March 11, 2025. Parker holders received up to 4,800,000 Nabors shares plus $562,000 in cash. Parker's $178.1 million second-lien loan stayed in place, and Nabors said it intended to refinance it. The year-end share count rose from 10,709,216 in 2024 to 15,722,454 in 2025. On August 20 Nabors sold Quail Tools, which it gained with Parker, to Superior Energy Services for $600 million: $375 million in cash and a $250 million secured note due May 20, 2026. Nabors said the sale cut its net debt by more than 25%. On November 10 it closed $700 million of 7.625% notes due 2032 to retire its 7.375% notes due 2027, of which $546.1 million was outstanding.
As of the latest beat, in November 2025, Nabors was a wholly owned-subsidiary structure under Nabors Industries Ltd, with Parker integrated. The outcomes of the Quail seller note, the Parker loan refinancing and the warrants' June 2026 expiry were not reported in the beats.
