Financial and Operating Details for the Three and Twelve Months Ended December 31, 2023

Revenue: Total revenue increased by 43% to $121.2 million for the year ended December 31, 2023, compared to $84.8 million for year ended in December 31, 2022. This increase was primarily due to a 43% increase in rental revenue to $106.2 million from $74.5 million during the same period. In addition, sales revenues increased by 4% to $8.9 million in 2023 compared to $8.6 million in 2022. Total revenue increased 61% to $36.2 million for the three months ended December 31, 2023, from $22.5 million for the three months ended December 31, 2022. This increase was primarily related to a $11.1 million increase in rental revenue driven by new unit set activity, rental rate increases, and surcharges. Total revenue increased 15% to $36.2 million for the three months ended December 31, 2023 from $31.4 million for the three months ended September 30, 2023. This increase was primarily related to a $3.9 million or 14% increase in rental revenue.

Gross Margin: Total gross margin increased to $32.9 million for the year ended December 31, 2023, from $14.9 million for the year ended December 31, 2022. Total adjusted gross margin, exclusive of depreciation, increased to $58.7 million for the year ended December 31, 2023, from $38.5 million for the same period ended December 31, 2022. Total gross margin increased to $13.3 million for the three months ended December 31, 2023, from $4.9 million for the three months ended December 31, 2022. Total adjusted gross margin, exclusive of depreciation, increased to $20.3 million for the three months ended December 31, 2023, from $10.7 million for the three months ended December 31, 2022. Sequentially, total gross margin increased to $13.3 million for the three months ended December 31, 2023 from $7.9 million for the three months ended September 30, 2023. Sequentially, total adjusted gross margin increased to $20.3 million for the three months ended December 31, 2023, from $14.6 million for the three months ended September 30, 2023. All of these increases are primarily attributable to increased rental revenues in excess of increased costs of rentals. Please see discussions of Non-GAAP Financial Measures – Adjusted Gross Margin, below.

Operating Income: The Company posted operating income for the year ended December 31, 2023, of $10.5 million, compared to operating income of $0.4 million for the year ended December 31, 2022. This improvement in operating income is primarily due to an increase in gross margin of $17.9 million driven by increased rental revenues. The improvement in the fourth quarter of 2023 versus 2022 operating income was primarily driven by a $6.9 million increase in rental gross margin. Sequentially, total operating income for the three months ended December 31, 2023 was $4.4 million compared to $4.9 million for the three months ended September 30, 2023. This decrease was due to an inventory allowance of $4.0 million related to our decision to cease new unit fabrication at our Midland, Texas fabrication facility.

Net Income (Loss): The Company reported net income of $4.7 million for the year ended December 31, 2023, compared to a net loss of $0.6 million for the year ended December 31, 2022. The improvement in 2023 annual net income, when compared to the full year 2022 results, is primarily due to our increased operating income, as discussed above, partially offset by an increase of $1.3 million in income tax expense in 2023. For the three months ended December 31, 2023, the Company reported net income of $1.7 million compared to a net loss of $0.8 million for the three months ended December 31, 2022. The improvement in net income was primarily attributable to an increase in operating income, as discussed above. Sequentially, the Company’s net income decreased $0.5 million to $1.7 million from $2.2 million primarily due to the inventory allowance of $4.0 million offset by higher rental and sales gross margins.

Earnings (loss) per share: For the year ended December 31, 2023, the Company reported earnings per basic share of $0.39 and per diluted share of $0.38, compared to loss per basic and diluted share of $0.05 for the year ended December 31, 2022. For the three months ended December 31, 2023, the Company reported earnings per basic and diluted share of $0.14 compared to a net loss per basic and diluted share of $0.06 for the three months ended December 31, 2022, and earnings per basic and diluted share of $0.18 for the three months ended September 30, 2023.

Adjusted EBITDA¹: Adjusted EBITDA increased $16.6 million to $45.8 million for the year ended December 31, 2023, compared to $29.2 million for the year ended December 31, 2022. This increase was primarily due to increased rental adjusted gross margin. Adjusted EBITDA increased to $16.3 million for the three months ended December 31, 2023, as compared to $7.8 million for the three months ended December 31, 2022, primarily due to an increase in rental adjusted gross margin (including higher than expected adjusted gross margin percentage) but also from an increase in sales adjusted gross margin. Sequentially, Adjusted EBITDA increased to $16.3 million from $11.8 million for the three months ended September 30, 2023, primarily due to an increase in rental adjusted gross margin (including higher than expected adjusted gross margin percentage) but also from an increase in sales adjusted gross margin. Please see discussion of Non-GAAP Financial Measures – Adjusted EBITDA, below.

Cash flow: At December 31, 2023, cash and cash equivalents were approximately $2.7 million, while working capital was $43.6 million with $164.0 million of outstanding bank borrowings. Cash flow from operating activities was $18.0 million for the year ended December 31, 2023. A significant build in accounts receivable materially reduced cash flow from operations; we expect this build to reduce over the course of 2024. Cash flow used in investing activities (consisting of our capital expenditures) was $153.9 million during 2023. Cash flow provided by financing activities was $135.2 million for the year ended December 31, 2023, which included $139.0 million of net borrowings under our revolving credit facility.

2024 Outlook

NGS’s full year 2024 Outlook is as follows:

	FY 2024 Outlook
Adjusted EBITDA	$58 million – $65 million
New Unit Capital Expenditures	$40 million – $50 million
Target Return on Invested Capital	At least 20%

Our current outlook for 2024 Fiscal Year Adjusted EBITDA is a range of $58 million to $65 million, a material increase from our previously announced outlook. The low end of this range reflects our current view as to the approximate amount of fourth quarter 2023 Adjusted EBITDA that is “run-rate” or likely to recur, then annualized for a full year number.

After a substantial capital expenditure program in 2023, we have a lower but still significant amount of capital expenditures for new units in 2024. Of the total current expected range of $40 million to $50 million, approximately $15 million relates to holdover from the 2023 new unit plan that will be completed and installed in 2024; the balance is the 2024 new unit plan that is expected to be completed and installed in late 2024 and/or early 2025. We are reviewing our capital plans to see if we will further increase new unit capital expenditures in 2024 although no decision has been made. Overall, our target is to generate at least a 20% return on growth capital expenditures.

Selected data: The tables below show, for the three months and year ended December 31, 2023 and 2022 revenues and percentage of total revenues, along with our gross margin and adjusted gross margin (exclusive of depreciation and amortization), as well as, related percentages of revenue for each of our product lines. Adjusted gross margin is the difference between revenue and cost of sales, exclusive of depreciation and amortization.

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

Non-GAAP Financial Measure – Adjusted Gross Margin: We define “Adjusted Gross Margin” as total revenue less cost of sales (excluding depreciation and amortization expense). Adjusted gross margin is included as a supplemental disclosure because it is a primary measure used by management as it represents the results of revenue and cost of sales (excluding depreciation and amortization expense), which are key operating components. Adjusted gross margin differs from gross margin in that gross margin includes depreciation 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 expense reflects the systematic allocation of historical property and equipment values over the estimated useful lives.

Adjusted gross margin has certain material limitations associated with its use as compared to gross margin. Depreciation expense is a necessary element of our costs and our ability to generate revenue. Management uses this non-GAAP measure as a supplemental measure to other GAAP results to provide a more complete understanding of the company’s performance. As an indicator of operating performance, adjusted gross margin should not be considered an alternative to, or more meaningful than, operating income as determined in accordance with GAAP. 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 gross margin, the most directly comparable GAAP financial measure, and reconciles it to adjusted gross margin:

(1) Non-GAAP Financial Measures – Adjusted EBITDA: “Adjusted EBITDA” reflects net income or loss before interest, taxes, depreciation and amortization, non-recurring severance expenses, non-cash stock compensation expense, an increase in inventory allowance and write-off and retirement of rental equipment and assets. Adjusted EBITDA is a measure used by management, analysts and investors as an indicator of operating cash flow since it excludes the impact of movements in working capital items, non-cash charges and financing costs. Therefore, Adjusted EBITDA gives the investor information as to the cash generated from the operations of a business. However, Adjusted EBITDA is not a measure of financial performance under accounting principles (GAAP) and should not be considered a substitute for other financial measures of performance. Adjusted EBITDA as calculated by NGS may not be comparable to Adjusted EBITDA as calculated and reported by other companies. The most comparable GAAP measure to Adjusted EBITDA is net (loss) income.

The following table reconciles our net (loss) income, the most directly comparable GAAP financial measure, to Adjusted EBITDA:
