Management Commentary and Outlook
“We are pleased to report another quarter of strong execution and continued momentum across our business,” said Justin Jacobs, Chief Executive Officer. “We are taking market share, expanding our presence in key basins, and investing in our fleet, including the deployment of large-horsepower electric motor units. Our recent credit facility expansion, which also decreased our interest rate and provided more flexible covenants, further improves our ability to take advantage of organic and inorganic growth opportunities.”

Jacobs continued, “While broader market uncertainty increased in recent weeks—driven primarily by tariff concerns, commodity price volatility, and macroeconomic factors—we are not seeing any meaningful direct impact on our operations. We will continue to monitor indirect effects closely, but we remain confident in our ability to deliver results consistent with our guidance.”

“We increased our EBITDA outlook to reflect our first quarter outperformance relative to internal expectations and our confidence in the trajectory of the business. We remain excited about our prospects as we look to the remainder of 2025 and into 2026. Our team remains focused on disciplined capital allocation, operational excellence, and long-term value creation for our shareholders.”

Corporate Guidance — 2025 Outlook

The Company today provides updates to its previously announced guidance for the 2025 Fiscal Year. Based on a strong start to the year in the first quarter and its confidence for the remainder of the year, the Company today increased the high-end of its adjusted EBITDA guidance to $79 million. The Company now anticipates adjusted EBITDA for the 2025 Fiscal Year to be in the range of $74 – $79 million.

The Company also reaffirms its outlook for 2025 growth capital expenditures of between $95 – $120 million, which are mostly  comprised of new units (essentially all of which are under contract). Once all these units are deployed, which is expected by early 2026, the Company expects its rented horsepower fleet to increase by approximately 90,000 horsepower, representing an increase of approximately 18% compared to year-end 2024. Customer deployments remain on schedule and the timing of deployments as previously noted is heavily weighted to the second half of 2025 and early 2026. Additionally, the Company anticipates 2025 maintenance expenditures of $10 – $13 million, consistent with its prior guidance and its target return on invested capital of 20% remains unchanged.

The Company also reiterates the statement from the 2024 year end release that once all the 2025 growth capital expenditures are spent and the units are deployed, its “run rate” Adjusted EBITDA should increase at a rate (when compared to the fourth quarter of 2024) well in excess of (but less than double the rate of) the Company’s anticipated horsepower growth of 18%.

Jacobs concluded, “We have multiple pathways to build on our industry-leading growth and drive shareholder value: fleet optimization, asset utilization (both unutilized units and non-cash assets), new rental units (both electric motor and natural gas engine), and accretive mergers and acquisitions. Given our strong balance sheet, low relative leverage, and recent increase in our borrowing capacity, we are well positioned to capitalize on opportunities for significant growth throughout the remainder of 2025.”

2025 First Quarter Financial Results

Revenue:  Total revenue for the three months ended March 31, 2025, increased 12% to $41.4 million from $36.9 million for the three months ended March 31, 2024. This increase was primarily due to higher rental revenues for the comparable periods. Rental revenue increased 15% to $38.9 million from $33.7 million in the first quarter of 2024 due to the addition of higher horsepower packages and pricing improvements. As of March 31, 2025, we had 492,679 rented horsepower (1,202 rented units) compared to 444,220 horsepower (1,245 rented units) as of March 31, 2024, reflecting an 11% increase in total utilized horsepower. Sequentially, total revenue increased 2% from $40.7 million primarily related to higher rental revenue for the current period.

Gross Margins and Adjusted Gross Margins: Total gross margins, including depreciation expense increased to $15.7 million for the three months ended March 31, 2025, compared to $14.2 million for the same period in 2024 and increased on a sequential basis from $14.6 million for the three months ended December 31, 2024. Total adjusted gross margin, exclusive of depreciation expense, increased to $24.3 million for the three months ended March 31, 2025, compared to $21.1 million for the same period in 2024. On a sequential basis, total adjusted gross margin, exclusive of depreciation expense increased by $1.3 million compared to $23.0 million for the period ended December 31, 2024. For a reconciliation of Gross Margin, see Non-GAAP Financial Measures – Adjusted Gross Margin, below.

Operating Income:  Operating income for the three months ended March 31, 2025, was $9.5 million compared to operating income of $9.3 million for the comparable 2024 period. On a sequential basis, operating income increased $3.5 million compared to $6.0 million for the period ended December 31, 2024.

Net Income: Net income for the three months ended March 31, 2025, was $4.9 million, or $0.38 per diluted share compared to net income of $5.1 million or $0.41 per diluted share for the comparable 2024 period. On a sequential basis, net income increased $2.0 million when compared to net income of $2.9 million, or $0.23 per diluted share, in the fourth quarter of 2024. The modest year-over-year decline in net income was primarily related to an adjustment to inventory allowance, retirement of rental equipment, a gain on the sale of property and equipment, as well as an increase in depreciation and amortization. The sequential improvement in net income was primarily driven by higher rental revenue and rental gross margin.

Cash Flows: At March 31, 2025, cash and cash equivalents were approximately $2.1 million, while working capital was $24.7 million. For the three months ended March 31, 2025, cash flows provided by operating activities were $21.3 million, while cash flows used in investing activities was $19.3 million. This compares to cash flows from operating activities of $5.6 million and cash flows used in investing activities of $10.9 million for the comparable three-month period in 2024. Cash flow used in investing activities during the first quarter 2025 included $19.3 million in capital expenditures.

Adjusted EBITDA: Adjusted EBITDA increased 14% to $19.3 million for the three months ended March 31, 2025, from $16.9 million for the same period in 2024. The increase was primarily attributable to higher rental revenue and rental adjusted gross margin. Sequentially, Adjusted EBITDA increased 7% when compared to $18.0 million for the three months ended December 31, 2024.

Debt:  Outstanding debt on our revolving credit facility as of March 31, 2025, was $168 million. Our leverage ratio at March 31, 2025, was 2.18x and our fixed charge coverage ratio was 2.98x. The Company is in compliance with all terms, conditions and covenants of the credit agreement.

Selected data: The tables below show revenue by product line, gross margin and adjusted gross margin for the trailing five quarters.   Adjusted gross margin is the difference between revenue and cost of sales, exclusive of depreciation.

(1) For a reconciliation of adjusted gross margin to its most directly comparable financial measure calculated and presented in accordance with GAAP, please read “Non-GAAP Financial Measures – Adjusted Gross Margin” below.

Non-GAAP Financial Measure – Adjusted Gross Margin: “Adjusted Gross Margin” is defined as 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 shows 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, as well as an increase in inventory allowance, impairments, retirement of rental equipment, nonrecurring restructuring charges including severance 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; (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:
