PATTERSON UTI ENERGY INC
Patterson-UTI Energy, Inc. is a Delaware corporation (Delaware Division of Corporations file number 2355146, LEI 254900XGFBKIXD6G0697, IRS employer identification number 75-2504748) with its principal executive offices at 10713 W. Sam Houston Pkwy N, Suite 800, Houston, Texas 77064. It provides drilling and completion services to oil and natural gas exploration and production companies, mainly onshore in the United States, and sells specialised drill bits internationally. Its common stock trades on the Nasdaq Global Select Market under the ticker PTEN. GLEIF lists the entity as active, with its Delaware registered office in Wilmington.
The business was formed in 1978 and reincorporated as a Delaware corporation in 1993, according to the company’s annual report for 2001. GLEIF records 14 October 1993 as the Delaware creation date. In Texas, the Comptroller of Public Accounts lists it as a foreign (Delaware) corporation with Secretary of State file number 0009728906, registered on 19 October 1993, with an active right to transact business. The company was called Patterson Energy, Inc. until 8 May 2001, when it merged with UTI Energy Corp. and took its current name.
Patterson-UTI Energy reports three segments. Drilling services covers contract drilling in the continental United States, Colombia and Ecuador (152 marketed land rigs at 31 December 2025), directional drilling, and electrical controls and automation. Completion services covers hydraulic fracturing, wireline and pumping, cementing, natural-gas fuelling and last-mile proppant logistics in basins including the Permian, Marcellus/Utica, Eagle Ford, Haynesville and Bakken. Drilling products, the Ulterra business, makes and rents PDC drill bits and downhole tools, serving energy and mining markets in more than 30 countries from manufacturing sites in Fort Worth, Leduc (Alberta) and Saudi Arabia.
The 10-K for 2025 reports consolidated operating revenues of $4,826.6 million (2024: $5,377.9 million) and a net loss attributable to common stockholders of $93.6 million (2024: $968.0 million, which included an $885.2 million goodwill impairment). The group had about 7,900 full-time employees on 31 January 2026. The 10-K states that Patterson-UTI Energy, Inc. itself has no employees or independent operations, so these are group-level figures.
Recent developments: the company completed its merger with NexTier Oilfield Solutions Inc. on 1 September 2023, closed its acquisition of Ulterra on 14 August 2023, and sold its oilfield rentals business in April 2025. Its website is www.patenergy.com, the address given in its SEC filings.

Shareholders
Shareholders of Patterson-UTI Energy, Inc.
Patterson-UTI Energy, Inc. is a publicly traded company whose common stock ($0.01 par value, its only class of common stock) is listed on the Nasdaq Global Select Market as PTEN. Its shareholders are not named in any register. Holders of more than 5% are disclosed through Schedule 13D/13G filings with the SEC and the company’s annual proxy statement. The 10-K reports 379,575,200 shares outstanding on 4 February 2026. The proxy statement filed on 13 April 2026 reports 379,602,464 shares outstanding on 31 March 2026.
The proxy statement lists these holders of more than 5%, each “based solely on” the holder’s most recent Schedule 13G filing at that date:
| Holder | Shares | Percent of class (proxy, 31 March 2026) | Underlying filing |
|---|---|---|---|
| BlackRock, Inc. | 55,550,653 | 14.6% | Schedule 13G/A filed 30 April 2025, holdings as of 31 March 2025. The filing itself reports 14.4%. |
| Blackstone (BEP Diamond Topco L.P. and related Blackstone entities) | 28,061,525 | 7.4% | Schedule 13G/A filed 8 August 2025, holdings as of 30 June 2025 |
| Dimensional Fund Advisors LP | 21,211,576 | 5.6% | Schedule 13G filed 9 April 2026, holdings as of 31 March 2026. The filing also reports 5.6%. |
The proxy reports that all current directors and executive officers as a group (14 persons) held 8,386,776 shares, or 2.2%.
Filings made after the proxy statement change this picture:
- Blackstone: Schedule 13G/A Amendment No. 3, filed 1 May 2026, reports 7,139,403 shares, or 1.9%, for the Blackstone reporting group as of 31 March 2026 (2,102,773 shares, or 0.6%, held by BEP Diamond Topco L.P.). It states that the reporting persons no longer own more than 5% and calls itself an exit filing. Blackstone’s stake dates from the 2023 Ulterra acquisition, which was paid partly in 34,900,000 Patterson-UTI shares.
- Vanguard Portfolio Management: Schedule 13G filed 29 April 2026 reports 27,192,996 shares, or 7.16%, as of 31 March 2026.
- Vanguard Capital Management: Schedule 13G filed 30 April 2026 reports 19,259,019 shares, or 5.07%, as of 31 March 2026.
- The Vanguard Group: Schedule 13G/A Amendment No. 12, filed 27 March 2026, reports 0 shares, or 0%, as of 13 March 2026.
No BlackRock filing later than the 30 April 2025 amendment appears in the issuer’s EDGAR filing index, so its figure may be more than a year old. Each percentage above is the figure stated in the filing or the proxy. They are investment-manager positions, typically held for clients, not a single owner’s stake.
Ultimate beneficial ownership
No filing discloses a controlling shareholder or a natural person who ultimately owns or controls Patterson-UTI Energy, Inc. It is a widely held listed company, and the largest disclosed holders are institutional investment managers. GLEIF records a reporting exception for the direct accounting-consolidation parent with the reason “no known person”, which is consistent with having no parent company.
Data availability
Shareholdings come from SEC filings only and are as of the dates shown. Holders below 5% do not have to file Schedule 13G, and passive 13G filers report changes periodically, so the current list may differ. Delaware does not publish shareholder lists for corporations.

Recent officer changes

The Form 8-Ks filed after the 4 June 2026 annual meeting, up to 28 October 2026, report no further director or officer changes under Item 5.02.
Data availability
Names and roles come only from SEC filings. Delaware publishes no officer list for corporations. The Pennsylvania Department of State open-data record for the company’s Pennsylvania foreign registration (0003057877) still lists Leslie A. Beyer as a director, so that register’s officer list was not up to date at retrieval. Nationality is not recorded in any of these sources.
