(4) Fleet utilization is calculated as (i) revenue-generating horsepower divided by (ii) fleet horsepower. Horsepower The 35.0% and 30.4% increases in fleet horsepower and revenue-generating horsepower, respectively, were primarily attributable to the compression assets acquired in the CSI Acquisition and the purchase and deployment of new compression units.
(4) Fleet utilization is calculated as (i) revenue-generating horsepower divided by (ii) fleet horsepower. Horsepower The 1.2% and 2.5% increases in fleet horsepower and revenue-generating horsepower, respectively, were mainly driven by the strategic acquisition and deployment of new large horsepower compression units throughout the period.
The 13.0% decrease in revenue-generating horsepower per revenue-generating compression unit was due to units acquired as part of the CSI Acquisition having, on average, less horsepower. 46 Table of Contents Financial Results of Operations The following table presents selected financial and operating information for the periods presented (in thousands) : Year Ended December 31, % Change 2024 2023 Revenues: Contract Services $ 1,034,173 $ 735,605 40.6 % Other Services 125,138 114,776 9.0 % Total revenues 1,159,311 850,381 36.3 % Operating expenses: Cost of operations (exclusive of depreciation and amortization shown below): Contract Services 355,016 257,092 38.1 % Other Services 103,360 93,779 10.2 % Depreciation and amortization 260,272 182,869 42.3 % Long-lived asset impairment 9,921 — 100.0 % Selling, general and administrative 151,680 73,308 106.9 % Loss (gain) on sale of assets 29,612 (777) n/m Total operating expenses 909,861 606,271 50.1 % Income from operations 249,450 244,110 2.2 % Other income (expenses): Interest expense (197,144) (222,514) (11.4) % Loss on extinguishment of debt — (6,757) (100.0) % Gain on derivatives 24,017 20,266 18.5 % Other (expense) income, net (415) 31 n/m Total other expenses (173,542) (208,974) (17.0) % Income before income taxes 75,908 35,136 116.0 % Income tax expense 25,574 15,070 69.7 % Net income 50,334 20,066 150.8 % Less: Net income attributable to noncontrolling interests 439 — 100.0 % Net income attributable to common shareholders $ 49,895 $ 20,066 148.7 % Revenues and Sources of Income Contract Services Contract Services revenue increased $298.6 million, or 40.6%, for the year ended December 31, 2024 compared to the year ended December 31, 2023.

Furthermore, there was also an increase of $1.9 million related to gas treating and cooling services.
Because we capitalize assets, depreciation and amortization of equipment is a necessary element of our costs. To compensate for the limitations of adjusted gross margin as a measure of our performance, we believe that it is important to consider gross margin determined under GAAP, as well as adjusted gross margin, to evaluate our operating profitability.
