On October 1, 2021, we completed the acquisition of Pioneer by acquiring 100% of its equity interests. Total consideration for the acquisition included the issuance of approximately 26.3 million shares of our common stock and payment of $30 million cash, which based on the closing price of our common stock of $9.44 on October 1, 2021, valued the transaction at approximately $278 million.

Pioneer provided land-based contract drilling services and production services to a diverse group of oil and natural gas exploration and production companies in the United States and internationally in Colombia.

The acquisition has been accounted for as a business combination using the acquisition method. Under the acquisition method of accounting, the fair value of the consideration transferred is allocated to the tangible and intangible assets acquired and the liabilities assumed based on their estimated fair values as of the acquisition date.

The total fair value of the consideration transferred was determined as follows (in thousands, except stock price):


Shares of our common stock issued to Pioneer shareholders		26,274
Our common stock price on October 1, 2021	$	9.44
Fair value of common stock issued	$	248,025
Plus cash consideration	$	30,007
Total fair value of consideration transferred	$	278,032

Approximately $41.5 million of revenues and $30.5 million of direct operating expenses attributed to the Pioneer acquisition are included in our consolidated statements of operations for the period from the closing date on October 1, 2021 through December 31, 2021, excluding the acquired well servicing rig business and the wireline businesses that have been presented as a discontinued operation in our consolidated statements of operations. Revenues and direct operating expenses for our discontinued operations are presented below. During 2021, we incurred costs related to the Pioneer acquisition totaling $12.1 million, which are included in our consolidated statements of operations as “Merger and integration expenses.”

The results of Pioneer’s operations since the Pioneer merger date of October 1, 2021, are included in our consolidated statements of operations. The following pro forma condensed combined financial information was derived from our and Pioneer’s historical financial

statements, excluding the well servicing rig business and wireline business that were disposed on December 31, 2021, and gives effect to the acquisition as if it had occurred on January 1, 2020. The below information reflects pro forma adjustments based on available information and certain assumptions we believe are reasonable, including (i) adjustments related to the depreciation and amortization of the fair value of acquired fixed assets, (ii) removal of the historical interest expense, loss on debt extinguishment and reorganization expenses of the acquired entities and (iv) the tax benefit of the aforementioned pro forma adjustments.

The pro forma results of operations do not include any cost savings or other synergies that may result from the Pioneer acquisition. The pro forma results of operations also do not include any estimated costs that have been or will be incurred to integrate Pioneer operations. The pro forma results of operations include our merger and integration-related costs of $12.1 million and Pioneer’s merger related costs of $4.6 million for the year ended December 31, 2021.

The pro forma condensed combined financial information has been included for comparative purposes and is not necessarily indicative of the results that might have actually occurred had the Pioneer acquisition taken place on January 1, 2020; furthermore, the financial information is not intended to be a projection of future results. The following table summarizes our selected financial information on a pro forma basis (in thousands, except per share data):

On December 31, 2021, we completed the sale of the acquired well servicing rig business and wireline business to Clearwell Dynamics, LLC. The sale price was $43.0 million in cash consideration, subject to customary purchase price adjustments at closing for cash and working capital. The results of operations of these businesses were presented as a discontinued operation in the consolidated financial statements during the fourth quarter of 2021.

Summarized operating results from discontinued operations that are included in our consolidated statements of operations for the year ended December 31, 2021 are shown below (in thousands):

On August 14, 2023, we completed the Ulterra acquisition. Total consideration for the acquisition included the issuance of 34.9 million shares of our common stock and payment of approximately $376 million of cash, which based on the closing price of our common stock of $14.94 on August 14, 2023, valued the transaction at closing at approximately $897 million.

The total fair value of the consideration transferred was determined as follows (in thousands, except stock price):


Shares of our common stock issued to Ulterra		34,900
Our common stock price on August 14, 2023	$	14.94
Common stock equity consideration	$	521,406
Plus net cash consideration (1)		375,740
Total consideration transferred	$	897,146

The aggregate purchase price noted above was allocated to the major categories of assets acquired and liabilities assumed based on preliminary estimated fair values as of the date of the business combination. We applied significant judgment in estimating the fair value of assets acquired and liabilities assumed, which involved the use of significant estimates and assumptions with respect to future rig counts, cash flow projections, estimated economic useful lives, operating and capital cost estimates, customer attrition rates, contributory asset charges, royalty rates and discount rate (10.5%). The carrying amounts of cash and cash equivalents, accounts receivable, other assets, accounts payable and accrued liabilities approximate their fair values due to their nature or the short-term maturity of instruments. The remaining assets acquired and liabilities assumed are based on inputs that are not observable in the market and thus represent Level 3 inputs. The fair value of inventory and rental equipment was determined using a replacement cost approach. Intangible assets primarily consist of customer relationships and developed technology, the fair values of which were determined using an income approach. Property and equipment was valued using a combination of indirect cost and a market approach. The fair value was estimated by using a multi-period excess earnings method for customer relationships and a relief from royalty method for trade name and developed technology. Certain data necessary to complete the purchase price allocation is not yet available, including final tax returns that provide the underlying tax basis of Ulterra’s assets and liabilities. The measurement period adjustments in the fourth quarter of 2023 did not have a material impact on our consolidated financial statements. We will complete the purchase price allocation during the 12-month period following the acquisition date.

The following table summarizes the fair values of the assets acquired and liabilities assumed at the date of acquisition:


Assets acquired:
Cash and cash equivalents	$	18,426

We recorded an adjustment of $5.5 million to write-up acquired drill bits classified as inventory to estimated fair value. This adjustment will be recorded as direct operating expense as acquired drill bits are sold.

The goodwill recognized in the acquisition represents the excess of the gross consideration transferred over the fair value of the underlying net tangible and identifiable intangible assets acquired and liabilities assumed. Goodwill represents the potential for new growth opportunities internationally with the acquisition of Ulterra as well as the recognition of deferred taxes for the difference between the fair value of the assets acquired and liabilities assumed and the respective carry-over tax basis. Goodwill is not deductible for tax purposes. All of the goodwill was assigned to our Drilling Products segment. See Note 7.

Approximately $135 million of revenues and $3.4 million of net loss attributed to the Ulterra acquisition are included in the consolidated statements of operations for the period from the closing date on August 14, 2023 through December 31, 2023. During the twelve months ended December 31, 2023, we incurred costs related to the Ulterra acquisition totaling $5.6 million, which are included in our consolidated statements of operations as “Merger and integration expense.”

A portion of the fair value consideration transferred has been provisionally assigned to identifiable intangible assets as follows:


	Fair Value		Weighted Average Useful Life

Trade name		16,000		11
Developed technology		52,000		5
Intangible assets	$	313,000

The following pro forma condensed combined financial information was derived from our and Ulterra’s historical financial statements and gives effect to the acquisition as if it had occurred on January 1, 2022. The below information reflects pro forma adjustments based on available information and certain assumptions we believe are reasonable, including (i) adjustments related to the depreciation and amortization of the step up to fair value of $77.6 million for acquired intangibles, $74.4 million for acquired drill bits classified as long-lived assets, and $5.5 million for acquired drill bits classified as inventory, (ii) removal of $12.8 million in 2023 and $28.1 million in 2022 of historical interest expense of the acquired entity and (iii) $17.4 million in 2023 and $11.3 million in 2022 of tax benefit relating to the aforementioned pro forma adjustments.

The pro forma results of operations do not include any anticipated cost savings or other synergies that may result from the Ulterra acquisition nor do they include any estimated costs that will be incurred to integrate Ulterra operations. The pro forma results of operations include our merger and integration expense of $5.6 million as if they had been incurred in the first quarter of 2022.

The pro forma condensed combined financial information has been included for comparative purposes and is not necessarily indicative of the results that might have actually occurred had the Ulterra acquisition taken place on January 1, 2022.

On September 1, 2023, we completed the NexTier merger. Under the terms of the merger agreement, NexTier became our wholly-owned subsidiary. Each share of NexTier common stock issued and outstanding immediately prior to the effective time of the merger was converted into the right to receive 0.752 shares of our common stock. Additionally, certain equity awards that were granted and outstanding under NexTier long-term incentive plans were assumed by us, and such equity awards were converted into equity awards in respect of our common stock in accordance with the merger agreement.

NexTier is a predominately U.S. land-focused oilfield service provider, with a diverse set of well completion and production services across a variety of active basins.

The total fair value of the consideration transferred was determined as follows (in thousands, except exchange ratio and stock price):


Number of shares of NexTier common stock outstanding as of September 1, 2023		228,846
Multiplied by the exchange ratio		0.752
Number of shares of Patterson-UTI Energy, Inc. common stock issued in connection with the merger		172,092

In connection with the merger, each of the share-based awards held by legacy NexTier employees were replaced with our share-based awards on the merger date. The fair value of the replacement awards has been allocated between each employee’s pre-combination and post-combination services. Amounts allocated to pre-combination services have been included as consideration transferred as part of the merger. See Note 12 for replacement awards details.

The transaction has been accounted for as a business combination using the acquisition method with Patterson-UTI Energy, Inc. determined to be the acquirer. Under the acquisition method of accounting, the fair value of the consideration transferred is allocated to the tangible and intangible assets acquired and the liabilities assumed based on their estimated fair values as of the acquisition date.

The aggregate purchase price noted above was allocated to the major categories of assets acquired and liabilities assumed based on preliminary estimated fair values as of the date of the business combination. We applied significant judgment in estimating the fair value of assets acquired and liabilities assumed, which involved the use of significant estimates and assumptions with respect to future rig counts, cash flow projections, estimated economic useful lives, operating and capital cost estimates, customer attrition rates, contributory asset charges, royalty rates and discount rate (14.0%). The carrying amounts of cash and cash equivalents, accounts receivable, inventory, other assets, accounts payable, accrued liabilities, and other liabilities approximate their fair values due to their nature or the short-term maturity of instruments. The remaining assets acquired and liabilities assumed are based on inputs that are not observable in the market and thus represent Level 3 inputs. The fair value of property and equipment was determined using a combination of replacement cost and indirect cost. Intangible assets were valued using an income approach. The fair value was estimated by using multi-period excess earnings method for customer relationships and a relief from royalty method for trade name and developed technology.

Total consideration transferred	$	2,799,308

The goodwill recognized in the merger represents the excess of the gross consideration transferred over the fair value of the underlying net tangible and identifiable intangible assets acquired and liabilities assumed. Goodwill largely consisted of the expected synergies and economies of scale from the combined operations of Patterson-UTI Energy, Inc. and NexTier as well as the recognition of deferred taxes for the difference between the fair value of the assets acquired and liabilities assumed and the respective carry-over tax basis. The goodwill is not deductible for tax purposes. All of the goodwill was assigned to our completion services segment. See Note 7.
