How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Filing Explained

At September 30, NGS reported $708 thousand in cash, $340.0 million in revolver debt and $139.8 million in borrowing availability, which is capacity, not cash.

The nine-month cash-flow statement records $9,999 thousand of common stock issued in connection with the acquisition, a completed issuance rather than an authorization.

At September 30, 2026, the balance sheet lists 14,214 thousand shares issued, versus 13,883 thousand at December 31, 2025; issuing additional shares increases the total share count and reduces existing holders’ percentage ownership absent offsetting changes.

At September 30, 2026, cash was $708 thousand and outstanding revolver debt was $340.0 million, with $139.8 million of availability under the borrowing base; that availability is borrowing capacity, not cash on hand.

Adjusted EBITDA financial
"Adjusted EBITDA increased 42.2% to $29.6 million"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
Adjusted Gross Margin financial
"Adjusted Gross Margin, exclusive of depreciation expense"
Adjusted gross margin is a measure of how much profit a company makes from its sales after accounting for certain expenses or one-time costs, but before deducting other operating expenses. It helps investors see the company's core profitability more clearly by removing factors that might distort the usual profit picture, similar to a runner measuring their speed without considering obstacles or weather. This metric provides a clearer view of the company's ongoing financial health.
fixed charge coverage ratio financial
"our fixed charge coverage ratio was 3.84x"
A fixed charge coverage ratio measures how well a company's operating income can cover its fixed, recurring obligations like interest payments and lease costs. Think of it as a safety margin — the higher the number, the more comfortably a business can pay steady bills from its normal earnings, which matters to investors because it signals financial stability, lower default risk, and greater ability to withstand revenue dips.
borrowing base financial
"reflecting the applicable borrowing base calculation"
A borrowing base is the amount a lender will allow a company to borrow based on the value of assets the company offers as security, typically things like accounts receivable and inventory. It matters to investors because it sets a practical ceiling on short-term financing and influences a company’s liquidity and risk: if the borrowing base falls, the company may lose access to cash or be forced to sell assets, which can affect operations and share value.

NGS Reports Third Quarter 2026 Financial and Operating Results;
Increases Quarterly Dividend and Provides Updated Guidance
SOUTHLAKE, Texas, November 9, 2026 (GLOBE NEWSWIRE) Natural Gas Services Group, Inc. (“NGS” or the “Company”) (NYSE: NGS), a leading provider of natural gas compression equipment, technology, and services to the energy industry, today announced financial results for the three months ended September 30, 2026.
Third Quarter 2026 Highlights
•Rental revenue of $58.9 million for the third quarter of 2026, representing a 41.9% year-over-year increase and a 19.1% sequential increase compared to the second quarter of 2026.
•Net income of $5.6 million, or $0.43 per diluted share, for the third quarter of 2026, compared to $5.8 million, or $0.46 per diluted share, for the third quarter of 2025 and $3.8 million, or $0.30 per diluted share, for the second quarter of 2026.
•Adjusted Net Income(1) of $6.2 million, or $0.48 per diluted share, for the third quarter of 2026, compared to $5.8 million, or $0.46 per diluted share, for the third quarter of 2025.
•Adjusted EBITDA(1) of $29.6 million for the third quarter of 2026, representing a 42.2% year-over-year increase and an 18.2% sequential increase, driven by the first full quarter of Flatrock operations and continued organic growth.
•Returned $5.2 million to shareholders through dividends year to date, including the third-quarter dividend of $0.15 per share, and increased the fourth-quarter dividend to $0.16 per share.
Management Commentary and Outlook
“NGS delivered another record quarter, marking the first full quarter of financial contribution from Flatrock,” said Justin Jacobs, Chief Executive Officer. “During the third quarter, rental revenue increased 42% year over year, Adjusted EBITDA increased 42% year over year, and horsepower utilization remained strong at 88%. These results reflect the hard work and dedication of our field service technicians, whose focus on reliability, uptime, and customer service continues to drive our operating performance."
“Integration of Flatrock continues to advance, with significant operational progress made to date. The addition of Flatrock is accelerating several of our strategic initiatives, particularly efforts to improve operating efficiency and leverage the capabilities of our combined organization. With a full quarter of Flatrock contribution, rental adjusted gross margin remained strong at 62.2%."
“We continue to execute against our four strategic growth and value drivers. During the third quarter, we added more than 20,000 horsepower organically, bringing our year-to-date additions to approximately 43,000 horsepower. More recently, we entered into an agreement for the sale of our Tulsa fabrication facility for $4.75 million, consistent with our focus on monetizing non-core assets and investing capital in higher-return opportunities. The sale is expected to be completed by the end of November 2026."
“Our strong operating performance supports the increase in our full-year 2026 Adjusted EBITDA guidance to $105 million to $108 million, raising the midpoint of our outlook. We are also increasing our quarterly dividend to $0.16 per share, reflecting growing earnings and confidence in the cash-generating capacity of our business.”
Corporate Guidance — 2026 Outlook
The Company now expects 2026 Adjusted EBITDA of $105 million to $108 million, compared to prior guidance of $103 million to $108 million. The updated guidance reflects strong operating performance, continued success integrating Flatrock, high utilization, and organic fleet expansion, balanced with expected inflationary pressures during the remainder of 2026.
Outlook
FY 2026 Adjusted EBITDA$105 million - $108 million
FY 2026 Growth Capital Expenditures$60 million - $75 million
FY 2026 Maintenance Capital Expenditures$15 million - $19 million
The Company has narrowed its 2026 growth capital expenditure guidance to $60 million to $75 million. The updated guidance excludes acquisition consideration and continues to reflect investments in large-horsepower units, including a significant number of electric motor drive compression units. Maintenance capital expenditure guidance remains unchanged at $15 million to $19 million.

Exhibit 99.1




The Company remains committed to disciplined capital allocation and investing in assets that generate attractive long-term returns. The Company's operating cash flow, $500 million credit facility, and significant borrowing capacity provide flexibility to fund organic growth, pursue accretive acquisitions, and return capital to shareholders.
Shareholder Returns
Quarterly Dividend: Our Board of Directors recently declared a quarterly cash dividend of $0.16 per share of common stock, payable on December 2, 2026, to stockholders of record at the close of business on November 19, 2026. The dividend represents a 6.7% increase from the third-quarter dividend of $0.15 per share and a 60% increase since the Company initiated its quarterly dividend at $0.10 per share in the third quarter of 2025.
Share Repurchase Program: The Company also has a $6.0 million share repurchase program in place, which expires in August 2027. No shares were repurchased during the third quarter of 2026.
2026 Third Quarter Financial Results
Revenue: Total revenue for the three months ended September 30, 2026, increased 41.1% to $61.3 million from $43.4 million for the three months ended September 30, 2025. This increase was primarily attributable to higher rental revenues for the comparable periods resulting from a full-quarter contribution from the Flatrock Acquisition, contracted fleet expansion, and continued pricing strength. Rental revenue increased 41.9% to $58.9 million from $41.5 million in the third quarter of 2025. As of September 30, 2026, we had 683,952 rented horsepower (1,529 utilized units) compared to 526,015 horsepower (1,235 utilized units) as of September 30, 2025, reflecting a 30.0% increase in total utilized horsepower.
Gross Margins and Adjusted Gross Margins(1): Total gross margins, including depreciation expense, increased to $23.3 million for the three months ended September 30, 2026, compared to $16.7 million for the same period in 2025. Total Adjusted Gross Margin, exclusive of depreciation expense, increased to $36.9 million for the three months ended September 30, 2026, compared to $25.8 million for the same period in 2025.
Operating Income: Operating income for the three months ended September 30, 2026, was $13.7 million compared to operating income of $10.8 million for the comparable 2025 period.
Net Income and Adjusted Net Income(1): Net income for the three months ended September 30, 2026, was $5.6 million, or $0.43 per diluted share, compared to net income of $5.8 million, or $0.46 per diluted share, for the comparable 2025 period and $3.8 million, or $0.30 per diluted share, for the three months ended June 30, 2026. The modest year-over-year decrease in net income was driven by strategic transaction costs and integration expenses of $0.8 million, attributable to the Flatrock Acquisition, largely offset by increases in rental revenue and the associated gross margin impact, including the full-quarter impact of the Flatrock Acquisition. Similarly, the sequential increase in net income was driven by increases in rental revenue and the associated gross margin impact, including the full-quarter impact of the Flatrock Acquisition and a reduction in strategic transaction costs and integration expenses attributable to the Flatrock Acquisition. Adjusted Net Income for the three months ended September 30, 2026, was $6.2 million, or $0.48 per diluted share, compared to Adjusted Net Income of $5.8 million, or $0.46 per diluted share, for the comparable 2025 period.
Cash Flows: For the three months ended September 30, 2026, cash flows provided by operating activities were $16.7 million, while cash flows used in investing activities were $25.9 million, including $25.9 million of capital expenditures, of which $20.6 million and $5.3 million represented growth and maintenance capital expenditures, respectively. This compares to cash flows from operating activities of $16.8 million and cash flows used in investing activities of $41.9 million for the comparable period in 2025.
Adjusted EBITDA(1): Adjusted EBITDA increased 42.2% to $29.6 million for the three months ended September 30, 2026, from $20.8 million for the same period in 2025. The increase was primarily attributable to higher rental revenue and rental adjusted gross margin, including the full-quarter contribution from the Flatrock Acquisition. Sequentially, Adjusted EBITDA increased 18.2% when compared to $25.1 million for the three months ended June 30, 2026.
Debt: Outstanding debt on our revolving credit facility as of September 30, 2026, was $340.0 million with $139.8 million of availability, reflecting the applicable borrowing base calculation. Our leverage ratio as of September 30, 2026, was 2.80x and our fixed charge coverage ratio was 3.84x. As of September 30, 2026, the Company was in compliance with all terms, conditions and covenants of the credit agreement.

Exhibit 99.1




Non-GAAP Financial Measure - Adjusted Net Income: “Adjusted Net Income” is a non-GAAP financial measure that we define as net income adjusted for nonrecurring interest income attributable to income tax refunds, impairments, nonrecurring restructuring charges, including severance, and costs directly attributable to strategic transactions and integration expenses, including for the Flatrock Acquisition, and income tax effects of these adjustments. We believe that Adjusted Net Income and Adjusted Net Income per share amounts provide meaningful supplemental information regarding our operational performance on a recurring basis.
The following tables reconcile our net income and diluted earnings per share, the most directly comparable GAAP financial measure, to Adjusted Net Income and Adjusted Net Income per diluted share:

Adjusted Net Income per diluted share$0.46 $0.33 $0.53 $0.47 $0.48 

Non-GAAP Financial Measure - Adjusted Gross Margin: “Adjusted Gross Margin” as defined by us is total revenue less costs of revenues (excluding depreciation and amortization expense). Adjusted Gross Margin is included as a supplemental disclosure because it is a primary measure used by our management as it represents the results of revenue and costs (excluding depreciation and amortization expense), which are key components of our operations. Adjusted Gross Margin differs from gross margin, in that gross margin includes depreciation and amortization expense. We believe Adjusted Gross Margin is important because it focuses on the current operating performance of our operations and excludes the impact of the prior historical costs of the assets acquired or constructed that are utilized in those operations. Depreciation and amortization expense does not accurately reflect the costs required to maintain and replenish the operational usage of our assets and therefore may not portray the costs from current operating activity. Rather, depreciation and amortization expense reflects the systematic allocation of historical property and equipment costs over their estimated useful lives.

Adjusted Gross Margin has certain material limitations associated with its use as compared to gross margin. These limitations are primarily due to the exclusion of depreciation and amortization expense, which is material to our results of operations. Because we use capital assets, depreciation and amortization expense is a necessary element of our costs and our ability to generate revenue. In order to compensate for these limitations, management uses this non-GAAP measure as a supplemental measure to other GAAP results to provide a more complete understanding of our performance. As an indicator of our operating performance, Adjusted Gross Margin should not be considered an alternative to, or more meaningful than, gross margin as determined in accordance with GAAP. Our Adjusted Gross Margin may not be comparable to a similarly titled measure of another company because other entities may not calculate Adjusted Gross Margin in the same manner.
The following table calculates our gross margin, the most directly comparable GAAP financial measure, and reconciles it to Adjusted Gross Margin:

Non-GAAP Financial Measures - Adjusted EBITDA: “Adjusted EBITDA” is a non-GAAP financial measure that we define as net income (loss) before interest, taxes, depreciation and amortization, amortization of capitalized technology implementation costs reported in selling, general and administrative expense, as well as an increase in inventory allowance, impairments, retirement of rental equipment, nonrecurring restructuring charges including severance, costs directly attributable to strategic transactions and integration, including the Flatrock Acquisition and non-cash equity-classified stock-based compensation expenses. This term, as used and defined by us, may not be comparable to similarly titled measures employed by other companies and is not a measure of performance calculated in accordance with GAAP. Adjusted EBITDA should not be considered in isolation or as a substitute for operating income, net income or loss, cash flows provided by operating, investing and financing activities, or other income or cash flow statement data prepared in accordance with GAAP. However, management believes Adjusted EBITDA is useful to an investor in evaluating our operating performance because: (i) it is widely used by investors in the energy industry to measure a company’s operating performance without regard to items excluded from the calculation of Adjusted EBITDA, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired, among other factors; (ii) it helps investors to more meaningfully evaluate and compare the results of our operations from period to period by removing the impact of our capital structure and asset base from our operating structure; and (iii) it is used by our management for various purposes, including as a measure of operating performance, in presentations to our Board of Directors, and as a basis for strategic planning and forecasting.
Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are as follows: (i) Adjusted EBITDA does not reflect all our cash expenditures, future requirements for capital expenditures, or contractual commitments; (ii) Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs; (iii) Adjusted EBITDA does not reflect the cash requirements necessary to service interest or principal payments on our debt and finance leases; and (iv) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any capital expenditures for such replacements.
The following table reconciles our net income, the most directly comparable GAAP financial measure, to Adjusted EBITDA:

•inability to finance our future capital requirements and availability of financing;
•cybersecurity threats, including increased use of artificial intelligence and other emerging technologies;
•capacity availability, costs and performance of our outsourced compressor fabrication providers and overall inflationary pressures;
•impacts of world events, such as acts of terrorism, the conflicts in Iran, Ukraine, Venezuela and in the greater Middle East, and significant economic disruptions and adverse consequences resulting from possible long-term effects of potential pandemics and other public health crises; and
•general economic conditions.
In addition, these forward-looking statements are subject to other various risks and uncertainties, including without limitation those set forth in the Company’s filings with the Securities and Exchange Commission, including the Company's Annual Report on Form 10-K for the year ended December 31, 2025, and its Quarterly Report on Form 10-Q for the quarter ended September 30, 2026.
