Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Total revenue increased 29.7% in Q3 and 36.7% for the nine months ended September 30, 2024, compared to the prior year. This was driven primarily by a 34.8% increase in rental revenue, attributed to higher rented horsepower (up 18.7% year-over-year) and a strategic shift toward high-horsepower units.
• Profitability: Net income more than doubled in Q3 (up 131%) and increased 372% for the nine-month period. Operating margins improved as cost of rentals decreased as a percentage of rental revenue (39% in 2024 vs. 49% in 2023) due to higher margins on large units.
• Expense Increases: Selling, General, and Administrative (SG&A) expenses rose 83% in Q3 and 20% for the nine months, driven by higher salaries, commissions, consulting fees, and public company costs. Interest expense surged 90% in Q3 and 399% for the nine months due to higher average borrowings and interest rates.
• Capital Deployment: Capital expenditures decreased significantly to $57.4M for the nine months ended September 30, 2024, compared to $128.6M in the prior year period, reflecting a more measured approach to fleet expansion.

Guidance, Outlook, and Risks

• Outlook: Management anticipates that cash flows from operations and borrowing capacity under the Amended and Restated Credit Agreement will provide adequate liquidity for planned capital expenditures through the remainder of 2024 and into 2025. The company plans to continue expanding its rental fleet, focusing on high-horsepower units, and optimizing asset utilization.
• Debt Facility: In June 2024, NGS amended its credit agreement to increase the potential aggregate commitment to $350.0 million. As of September 30, 2024, $163.0 million was outstanding with approximately $131.1 million available for borrowing. The weighted average interest rate was 8.82%.
• Material Weakness in Internal Controls: Management concluded that internal control over financial reporting was not effective as of September 30, 2024, due to a material weakness related to inventory processes (specifically year-end physical counts and approval of adjusting entries). A remediation plan is underway, including hiring additional management and implementing new IT controls.
• Risks: Key risks include dependence on oil and gas prices, competition, the ability to finance capital expenditures, and the potential for actual results to differ from forward-looking statements due to industry volatility.

Investor Verification Checklist

• Inventory Controls: Verify the progress of the remediation plan for the material weakness in inventory controls and assess the risk of future inventory misstatements.
• Debt Covenants: Confirm continued compliance with leverage and fixed charge coverage ratios under the amended credit facility, especially given the high interest rate environment.
• Capital Expenditure Sustainability: Monitor the balance between operating cash flow generation and capital spending to ensure the company can fund fleet expansion without excessive dilution or covenant breaches.
• High-Horsepower Strategy: Validate the sustainability of the margin improvement driven by the shift to high-horsepower units and the demand outlook for these specific assets.
• Interest Rate Exposure: Assess the impact of rising interest rates on future net income, given the significant increase in interest expense and the variable rate nature of the credit facility.
