Natural Gas Services Group is no longer a small Permian rental shop waiting for organic horsepower to compound on its own. The June close of Flatrock Compression turned the company into a scaled gas-lift platform that bought density, electric-drive mix, and two new public producers in a single stroke. That is the change the second-quarter print is really about. Record rental revenue and record adjusted earnings before interest, taxes, depreciation, and amortization arrived beside a GAAP earnings decline, because deal costs and revolver interest absorbed the operating lift. The market still prices the equity as a mid-cap rental franchise rather than a completed platform shift.
The tension sits in the gap between cash generation and reported profit. Rental revenue reached $49 million. Adjusted EBITDA printed $25 million. Net income fell even as the fleet worked harder, because selling costs jumped on transaction expense and interest rose with a much larger revolver balance. Horsepower utilization hit a record in the high eighties, and the large-horsepower book was essentially full. Pricing on a pro forma horsepower basis still climbed, even as rental adjusted gross margin eased sequentially from the first-quarter peak. Inflation in labor, lubricants, and parts is no longer a footnote.
The open question is whether Flatrock's first full half, plus a raised organic deployment plan, converts the new full-year adjusted EBITDA guide into cash after growth spending. Occidental and Devon still supplied most of first-half revenue. Bank leverage sits under the covenant ceiling but well above the pre-deal level. Shares closed at $35.37 on the publication date, inside a fifty-two-week band from the mid-twenties to the mid-forties. The second half either proves the platform is earning its new scale, or concentration and interest keep GAAP earnings stuck while the fleet works harder.
