Nine Energy Service Announces Fourth Quarter and Full Year 2024 Results

HOUSTON – Nine Energy Service, Inc. (“Nine” or the “Company”) (NYSE: NINE) reported fourth quarter 2024 revenues of $141.4 million, net loss of $(8.8) million, or $(0.22) per diluted share and $(0.22) per basic share, and adjusted EBITDA of $14.1 million. The Company had provided original fourth quarter 2024 revenue guidance between $132.0 and $142.0 million, with actual results coming in the upper end of the provided range.

“We had a good Q4 with revenue increasing sequentially, despite a flat average US rig count and typical Q4 seasonality,” said Ann Fox, President and Chief Executive Officer, Nine Energy Service.

“The Nine team had many accomplishments in 2024, despite a challenging backdrop for the oilfield service sector. Over the past several years, we have seen significant US rig declines, driven mostly by a depressed natural gas price, which averaged around $2.19 for 2024. Nine’s earnings have historically moved in tandem with the US rig count, which will continue to be a significant driver for Nine moving forward. However, in 2024 we created and implemented a two-pronged strategy of market share gains and cost reductions enabling us to drive profitability in a declining rig count environment. We began to see the impacts of this strategy in Q3, which continued into Q4 with sequential revenue increases despite a flat average US rig count and typical Q4 seasonality impacts.”

“Our cementing team was the largest driver of revenue and profitability growth, increasing quarterly cementing revenue by approximately 20% from Q2 to Q4, despite the 2024 US rig count reaching a trough in Q4. We exited 2024 with a Q4 cementing market share within the regions we operate of approximately 19%, an increase of approximately 14% over our Q4 2023 market share. Our completion tools team continued a relentless focus on technology in 2024, fielding multiple new technologies like the Pincer Hybrid Frac Plug and our new frac dart element. We remain bullish on the dissolvable plug thesis, especially as lateral lengths continue to expand. Technology innovation will continue to be a key focus in 2025 with the introduction of a new, state-of-the-art R&D and completion tools testing facility.”

“Safe operations are essential and drive operational excellence, sustain morale, and create cohesion in the team from the field to the corporate office. This year, our Total Recordable Incident Rate (“TRIR”) declined approximately 22% from 2023 to a 0.49, and the severity of our incidents also dropped. We launched our first Sustainability Report in 2024 which includes tough-to-get measurements for a corporation of our size.”

“It is a very dynamic time, but we are optimistic looking into 2025 as we continue to execute our strategy, expanding on our market share gains and cost cutting initiatives we began implementing in 2024. We believe the long-term demand for natural gas will increase. Our revenue is over 30% levered to natural gas basins, and activity increases within these basins would have positive impacts on Nine’s revenue and profitability.”

“With what we know today, we expect 2025 US activity levels to be mostly stable. Despite weather impacts in January and relatively flat activity levels thus far in Q1, we anticipate both revenue and profitability to increase sequentially in Q1 compared to Q4 as we sustain and build-on our market share gains and cost cutting initiatives.”

“We are constantly challenging ourselves to find ways to drive profitability for Nine. Our team is experienced and motivated. We are focused on continuing to execute our strategy and increasing profitability, and I am looking forward to seeing what we can accomplish in 2025.”

^AAdjusted EBITDA is defined as EBITDA (which is net income (loss) before interest, taxes, and depreciation and amortization) further adjusted for (i) goodwill, intangible asset, and/or property and equipment impairment charges, (ii) transaction and integration costs related to acquisitions, (iii) fees and expenses relating to our units offering and other refinancing activities, (iv) loss or gain on revaluation of contingent liabilities, (v) loss or gain on the extinguishment of debt, (vi) loss or gain on the sale of subsidiaries, (vii) restructuring charges, (viii) stock-based compensation and cash award expense, (ix) loss or gain on sale of property and equipment, and (x) other expenses or charges to exclude certain items which we believe are not reflective of ongoing performance of our business, such as legal expenses and settlement costs related to litigation outside the ordinary course of business. Management believes adjusted EBITDA provides useful information to us and our investors regarding our financial condition and results of operations because it allows us and them to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure and helps identify underlying trends in our operations that could otherwise be distorted by the effect of impairments, acquisitions and dispositions and costs that are not reflective of the ongoing performance of our business.

^BAdjusted gross profit (loss) is defined as revenues less cost of revenues excluding depreciation and amortization. This measure differs from the GAAP definition of gross profit (loss) because we do not include the impact of depreciation and amortization, which represent non-cash expenses. Our management believes adjusted gross profit (loss) provides useful information to us and our investors regarding our financial condition and results of operation and helps management evaluate our operating performance by eliminating the impact of depreciation and amortization, which we do not consider indicative of our core operating performance.

^CAdjusted return on invested capital (“adjusted ROIC”) is defined as adjusted after-tax net operating profit (loss), divided by average total capital. We define adjusted after-tax net operating profit (loss), which is a non-GAAP measure, as net income (loss) plus (i) goodwill, intangible asset, and/or property and equipment impairment charges, (ii) transaction and integration costs related to acquisitions, (iii) fees and expenses relating to our units offering and other refinancing activities, (iv) interest expense (income), (v) restructuring charges, (vi) loss (gain) on the sale of subsidiaries, (vii) loss (gain) on extinguishment of debt, and (viii) the provision (benefit) for deferred income taxes. We define total capital as book value of equity (deficit) plus the book value of debt less balance sheet cash and cash equivalents. We compute and use the average of the current and prior period-end total capital in determining adjusted ROIC. Management believes adjusted ROIC provides useful information to us and our investors regarding our financial condition and results of operations because it quantifies how well we generate operating income relative to the capital we have invested in our business and illustrates the profitability of a business or project taking into account the capital invested, and management uses adjusted ROIC to assist them in capital resource allocation decisions and in evaluating business performance.
