Two of the most important energy-producing regions in the United States sit in Texas. The Permian Basin, stretching across West Texas and into southeastern New Mexico, is the country’s most productive oil and gas region. The Eagle Ford, located in South Texas, is a major shale play known for its rich mix of oil, natural gas, and natural gas liquids. Together, these two basins hold vast reserves of crude oil, natural gas, and natural gas liquids, and their proximity to Gulf Coast refining and processing centers makes them especially valuable to the broader energy supply chain.
Operating right in the middle of this activity is Natural Gas Services Group, Inc. (NYSE: NGS), a Southlake, Texas-based company that rents, designs, installs, services, and maintains compression equipment for oil and gas producers and midstream companies. Compression is a critical part of the production process: it keeps natural gas moving through pipelines and processing facilities. NGS serves customers across the Permian Basin, Eagle Ford, and other major U.S. basins, making it one of the more infrastructure-dependent players in the domestic energy sector.
NGS has announced it had completed the acquisition of Flatrock Compression Holdings, a private compression services company with operations in both the Permian Basin and the Eagle Ford. The deal came in at $120 million total, structured as $110 million in cash and $10 million in newly issued NGS common stock.
The numbers behind the acquisition are worth looking at closely. Flatrock brings a rental compression fleet of approximately 86,000 horsepower to the table, with a significant portion made up of large horsepower units and electric motor driven units. That fleet is currently running at 95% utilization by horsepower, which is a strong figure in any capital equipment business. The purchase price translates to roughly 6.2 times Flatrock’s first-quarter 2026 annualized adjusted EBITDA, a metric that reflects operating profitability before interest, taxes, depreciation, and amortization. NGS described the deal as immediately accretive, meaning it is expected to add to key financial results from day one, without a long integration runway before the benefits show up.
To fund the deal, NGS amended its credit facility, increasing the committed amount from $400 million to $500 million, while retaining a $100 million accordion feature that can be used to push the maximum commitment to $600 million, subject to lender approval. Even after closing, the company’s pro-forma leverage ratio sits at approximately 3 times, which leaves meaningful room on the balance sheet.
The timing of this acquisition also connects to something bigger playing out across the energy sector. Rapid growth in AI data center power demand is driving a resurgence in fossil fuel investment, with planned natural gas capacity rising from 11.1% in 2024 to 18.1% in 2026 and planned non-renewable additions surging 71% between 2025 and 2026. Meeting the power demand from AI will likely require the U.S. to increase natural gas production by 10% to 15% by the early 2030s. That kind of demand creates a direct tailwind for companies that keep natural gas infrastructure running, and NGS sits squarely in that path.
Beyond the financial mechanics, Flatrock adds customer diversification and new large-account relationships that NGS did not previously have. The combined fleet is also more capable on the large horsepower and electric motor driven side, two categories that are increasingly important as producers push for greater efficiency and lower emissions in their compression operations. Founded in 2001, Flatrock has built a reputation in field operations and customer service that NGS management cited as a cultural fit, not just a financial one.
The Flatrock deal reflects a company that knows its market and moved on an asset that fits its existing strengths, without stretching its balance sheet to get there.
