Business Transactions | 4. Business Transactions July 2021 Dispositions In July 2021, we completed sales of certain contract operations customer service agreements and approximately 575 compressors, comprising approximately 100,000 horsepower, used to provide compression services under those agreements, as well as other assets used to support the operations. We allocated customer-related and contract-based intangible assets based on a ratio of the horsepower sold relative to the total horsepower of the asset group. We received cash consideration of $60.3 million for the sales and recorded gains on the sales of $13.0 million in gain on sale of assets, net in our consolidated statements of operations during the year ended December 31, 2021. February 2021 Disposition In February 2021, we completed the sale of certain contract operations customer service agreements and approximately 300 compressors, comprising approximately 40,000 horsepower, used to provide compression services under those agreements as well as other assets used to support the operations. We allocated customer-related and contract-based intangible assets based on a ratio of the horsepower sold relative to the total horsepower of the asset group. We recorded a gain on the sale of $6.0 million in gain on sale of assets, net in our consolidated statements of operations during the year ended December 31, 2021. July 2020 Disposition In July 2020, we completed the sale of the turbocharger business included within our aftermarket services segment. In connection with the sale, we entered into a supply agreement to purchase a minimum amount of turbocharger goods and services over a two-year term. In addition to cash of $9.5 million received upon closing, an additional $3.0 million was received on the first anniversary of the closing date in July 2021, and $3.5 million was received through the purchase of turbocharger goods and services under the supply agreement, including $2.8 million that was received during the year ended December 31, 2021. We recognized a gain on the sale of $9.3 million in gain on sale of assets, net in our consolidated statements of operations during the year ended December 31, 2020. March 2020 Disposition In March 2020, we completed the sale of certain contract operations customer service agreements and approximately 200 compressors, comprising approximately 35,000 horsepower, used to provide compression services under those agreements as well as other assets used to support the operations. We allocated customer-related and contract-based intangible assets and goodwill based on a ratio of the horsepower sold relative to the total horsepower of the asset group. We recognized a gain on the sale of $3.2 million in gain on sale of assets, net in our consolidated statements of operations during the year ended December 31, 2020. Elite Acquisition In August 2019, we completed the Elite Acquisition whereby we acquired from Elite Compression substantially all of its assets, including a fleet of predominantly large compressors comprising approximately 430,000 horsepower, vehicles, real property and inventory, and certain liabilities for aggregate consideration consisting of $214.0 million in cash and 21.7 million shares of common stock with an acquisition date fair value of $225.9 million. The cash portion of the acquisition was funded with borrowings under the Credit Facility. The Elite Acquisition was accounted for using the acquisition method, which requires, among other things, assets acquired and liabilities assumed to be recorded at their fair value on the acquisition date. The excess of the consideration transferred over those fair values was recorded as goodwill. Our valuation methodology and significant inputs for fair value measurements are detailed by asset class below. The fair value measurements for property, plant and equipment and intangible assets were based on significant inputs that are not observable in the market and therefore represent Level 3 measurements. Goodwill The goodwill resulting from the acquisition was attributable to the expansion of our services in various regions in which we currently operate and was allocated to our contract operations segment. The goodwill had an indefinite life that was to be reviewed annually for impairment or more frequently if indicators of potential impairment existed. All of the goodwill recorded for this acquisition is expected to be deductible for U.S. federal income tax purposes. See Note 9 (“Goodwill”) for details on the 2020 impairment of our goodwill. Property, Plant and Equipment The property, plant and equipment is primarily comprised of compression equipment that will be depreciated on a straight-line basis over an estimated average remaining useful life of 15 years. The fair value of the property, plant and equipment was determined using the cost approach, whereby we estimated the replacement cost of the assets by evaluating recent purchases of similar assets or published data, and then adjusted replacement cost for physical deterioration and functional and economic obsolescence, as applicable. Intangible Assets The intangible assets consist of customer relationships that have an estimated useful life of 15 years. The amount of intangible assets and their associated useful life were determined based on the period over which the assets are expected to contribute directly or indirectly to our future cash flows. The fair value of the identifiable intangible assets was determined using the multi-period excess earnings method, which is a specific application of the discounted cash flow method, an income approach, whereby we estimated and then discounted the future cash flows of the intangible asset by adjusting overall business revenue for attrition, obsolescence, cost of sales, operating expenses, taxes and the required returns attributable to other contributory assets acquired. Significant estimates made in arriving at expected future cash flows included our expected customer attrition rate and the amount of earnings attributable to the assets. To discount the estimated future cash flows, we utilized a discount rate that was at a premium to our weighted average cost of capital to reflect the less liquid nature of the customer relationships relative to the tangible assets acquired. Unaudited Pro Forma Financial Information Unaudited pro forma financial information for the year ended December 31, 2019 was derived by adjusting our historical financial statements in order to give effect to the assets and liabilities acquired in the Elite Acquisition. The Elite Acquisition is presented in this unaudited pro forma financial information as though the acquisition occurred as of January 1, 2018, and reflects the following:
| • | the acquisition of substantially all of Elite Compression’s assets, including a compression fleet of approximately 430,000 horsepower, vehicles, real property and inventory, and certain liabilities;
| • | borrowings of $214.0 million under the Credit Facility for cash consideration exchanged in the acquisition; and
| • | the exclusion of $7.8 million of financial advisory, legal and other professional fees incurred related to the acquisition and recorded to transaction-related costs in our consolidated statements of operations during the year ended December 31, 2019.
The unaudited pro forma financial information below is presented for informational purposes only and is not necessarily indicative of our results of operations that would have occurred had the transaction been consummated at the beginning of the period presented, nor is it necessarily indicative of future results. ​

​ The results of operations attributable to the assets and liabilities acquired in the Elite Acquisition have been included in our consolidated financial statements as part of our contract operations segment since the date of acquisition. Revenue attributable to the assets acquired from the date of acquisition, August 1, 2019, through December 31, 2019 was $33.2 million. We are unable to provide earnings attributable to the assets and liabilities acquired since the date of acquisition as we do not prepare full stand-alone earnings reports for those assets and liabilities. Harvest Sale In August 2019, we completed an asset sale in which Harvest acquired from us approximately 80,000 active and idle compression horsepower, vehicles and parts inventory for cash consideration of $30.0 million. We recorded a $6.6 million gain on this sale to gain on sale of assets, net in our consolidated statements of operations during the year ended December 31, 2019. The assets were previously reported under our contract operations segment.
