Management Commentary

“Operationally, NexTier delivered another very strong quarter with improved profitability and returns, even in a counter-seasonal period,” said Robert Drummond, President and Chief Executive Officer of NexTier. “We believe demand for our services continues to exceed supply, and our natural gas fueled fleet is creating significant value by lowering fuel costs. As a result, pricing is still moving higher. The sold out nature of the frac industry is putting a premium on service quality, and we are confident that our wellsite integration strategy offers a superior product for our customers and should continue to earn a premium return for NexTier investors.”

“For 2023, our outlook remains as strong as what we saw in 2022,” Mr. Drummond continued. “We expect oil drilling rig count to only increase slightly throughout the year, but believe there is already current unmet demand of 20-25 frac fleets in oil basins at the current rig count, which will likely be sufficient to absorb all newbuilds and reactivations this year, as well as nearly all capacity that might free up if near term demand weakens in natural gas basins. In addition, lower natural gas prices place an even greater premium on our natural gas powered fleet and our Power Solutions natural gas fueling business.”

Mr. Drummond concluded, “I would like to thank all of our hard-working employees for their efforts in a pivotal year for NexTier. We are excited about our prospects for 2023, and we look forward to delivering another year of strong results for our employees, our customers, and our investors.”

“We have remained steadfast in our strategy to prioritize strong returns and free cash flow, and our success is very apparent in our 2022 financial performance,” said Kenny Pucheu, Executive Vice President & Chief Financial Officer of NexTier. “Fundamentals in the oilfield services sector have improved significantly over the past couple of years, and our intense focus on timely investments and capital discipline has allowed us to generate industry leading returns. We see additional upside in 2023. We believe that a balanced focus on returns, free cash flow, and growth is the best strategy for our company, and our growing operating margins are proof that our strategy is working.”

“We remain committed to return at least half of our free cash flow to our investors,” continued Mr. Pucheu. “Following our Q3 2022 earnings, we initiated a shareholder return program. In just over three months, we have repurchased nearly 6% of the shares that were outstanding prior to commencement of the program. This should demonstrate conviction in our outlook on the industry, as well as conviction in our strategy. We are very excited about the opportunities for the Company over the next several years, and we will continue to prudently deploy every dollar of capital to the highest return project while rewarding our shareholders through the entire cycle.”

Full Year 2022 Financial Results

Revenue totaled $3.24 billion for the year ended December 31, 2022, compared to $1.42 billion for the year ended December 31, 2021. The revenue increase was primarily driven by higher demand for our services including an increase in frac activity, further penetration of our wellsite integration strategy, and higher pricing relative to the prior year. Additionally, 2022 included a full year of Alamo revenue compared to only four months in 2021. Net income was $315.0 million, or $1.26 per diluted share, for the year ended December 31, 2022, compared to a net loss of $119.4 million, or $0.53 per diluted share, for the year ended December 31, 2021.

Fourth Quarter 2022 Financial Results

Revenue totaled $870.9 million in the fourth quarter of 2022, compared to $896.0 million in the third quarter of 2022. Demand for our services remained strong and pricing continued to strengthen during the quarter, which was offset by normal seasonal headwinds as well as lower product sales as we saw a mix shift to lower revenue, higher return work relative to the third quarter.

Net income totaled $133.0 million, or $0.54 per diluted share, in the fourth quarter of 2022, compared to net income of $104.7 million, or $0.42 per diluted share in the third quarter of 2022. Adjusted net income totaled $145.8 million, or $0.59 per diluted share, in the fourth quarter of 2022, compared to adjusted net income of $129.5 million, or $0.52 per diluted share, in the third quarter of 2022.

Selling, general and administrative expense (“SG&A”) totaled $36.9 million in the fourth quarter of 2022, compared to SG&A of $37.4 million in the third quarter of 2022. Adjusted SG&A(1) totaled $29.7 million in the fourth quarter of 2022, compared to adjusted SG&A of $29.2 million in the third quarter of 2022.

Adjusted EBITDA totaled $212.7 million in the fourth quarter of 2022, compared to adjusted EBITDA of $194.8 million in the third quarter of 2022.

Fourth Quarter 2022 Management Adjustments

EBITDA(1) for the fourth quarter of 2022 was $199.9 million. When excluding net management adjustments of $12.8 million, adjusted EBITDA for the fourth quarter of 2022 was $212.7 million. Management adjustments included $7.1 million in stock compensation expense and a net $5.7 million in other adjustments, which includes the finalization of the last earnout for the Alamo Acquisition.

Completion Services

Revenue in our Completion Services segment totaled $829.8 million in the fourth quarter of 2022, compared to $857.8 million in the third quarter of 2022. The sequential decline was due to normal seasonal headwinds and a mix shift to lower revenue, higher return work, partially offset by continued strong demand and additional pricing improvements. Adjusted gross profit(1) totaled $227.5 million in the fourth quarter of 2022, compared to $205.7 million in the third quarter of 2022.

Well Construction and Intervention Services

Revenue in our Well Construction and Intervention (“WC&I”) Services segment, totaled $41.1 million in the fourth quarter of 2022, compared to $38.3 million in the third quarter of 2022. The sequential improvement was primarily driven by increased customer activity and pricing in our Cement product line. Adjusted gross profit totaled $10.5 million in the fourth quarter of 2022, compared to adjusted gross profit of $7.6 million in the third quarter of 2022.

Balance Sheet and Capital

Total debt outstanding as of December 31, 2022 was $361.4 million, net of unamortized deferred financing costs and unamortized debt discount, excluding finance lease obligations. As of December 31, 2022, total available liquidity was $633.8 million, comprised of cash of $218.5 million, and $415.3 million of available borrowing capacity under our asset-based credit facility, which remains undrawn.

Total cash provided by operating activities during the fourth quarter of 2022 was $144.1 million and cash used by investing activities was $50.8 million, resulting in a free cash flow of $93.2 million in the fourth quarter of 2022.

Investor Presentation and CEO Message

NexTier published an updated Investor Presentation to be viewed alongside this earnings release and also released a message from our President and CEO Robert Drummond. To access the Investor Presentation and message from our President and CEO, please visit our Investor Relations page at www.nextierofs.com. The contents of the website, the Investor Presentation and the CEO’s message are not incorporated by reference into this release.

Outlook

For the first quarter of 2023, we expect revenue will be up at least 6%, sequentially. Customer demand remains strong and we have had an encouraging start to the year, with limited impact from startup inefficiencies after the holiday break. Winter weather will have an impact on our Q1 results, although the expected impact is included in the guidance.

Consistent with prior guidance, our 2023 capital expenditure budget remains $350 million, in line with our 8-9% of revenue commitment, with spending weighted towards the first half of the year.

We expect to generate at least $500 million of free cash flow in 2023.

Mr. Drummond concluded, “Frac fundamentals are as strong as they have been in many years. The world is looking to limit the societal impacts of energy and commodity inflation, and doing so will require an increase in oil and gas production even as the world builds out new energy solutions. US shale will undoubtedly play a critical role in solving the world’s long-term energy needs. In order for US shale to maintain its competitiveness, the oilfield services sector will need to invest responsibly to attract capital and drive the next leg of efficiency. The next phase in shale’s development will require a strong and profitable OFS sector, and NexTier is prepared to do our part to help the industry responsibly move forward.”

(1)Non-GAAP Financial Measures. The Company has included in this press release or discussed on the conference call described above certain non-GAAP financial measures, some of which are calculated on segment basis or product line basis. These measurements provide supplemental information which management believes is useful to analysts and investors to evaluate our ongoing results of operations, when considered alongside GAAP measures such as net income and operating income. You should not consider them in isolation from, or as a substitute for, analysis of our results under GAAP.

Non-GAAP financial measures include EBITDA, adjusted EBITDA, adjusted EBITDA per deployed fleet, annualized adjusted EBITDA per deployed fleet, adjusted gross profit, adjusted net income (loss), adjusted net income (loss) per share, free cash flow, cash flow conversion, adjusted SG&A, net debt, invested capital, average invested capital, return on invested capital, annualized return on invested capital, total capital, average total capital, and return on total capital. These non-GAAP financial measures exclude the financial impact of items management does not consider in assessing the Company’s ongoing operating performance, and thereby facilitate review of the Company’s operating performance on a period-to-period basis. Other companies may have different capital structures, and comparability to the Company’s results of operations may be impacted by the effects of acquisition accounting on its depreciation and amortization. As a result of the effects of these factors and factors specific to other companies, the Company believes EBITDA, adjusted EBITDA, adjusted EBITDA per deployed fleet, annualized adjusted EBITDA per deployed fleet, adjusted gross profit, adjusted net income (loss), adjusted net income (loss) per share, and adjusted SG&A provide helpful information to analysts and investors to facilitate a comparison of its operating performance to that of other companies. The Company believes free cash flow, free cash flow conversion, and net debt provide investors a useful measure to assess management’s effectiveness in the areas of profitability and capital management. Invested capital, average invested capital, return on invested capital, annualized return on invested capital, total capital, average total capital, and return on total capital are presented based on the Company’s belief that these non-GAAP measures are useful information to investors and management when comparing profitability and the efficiency with which capital has been employed over time relative to other companies.

For a reconciliation of these non-GAAP measures, please see the tables at the end of this press release. Reconciliations of forward-looking non-GAAP financial measures to comparable GAAP measures are not available due to the challenges and impracticability with estimating some of the items, particularly with estimates for certain contingent liabilities, and estimating non-cash unrealized fair value losses and gains which are subject to market variability and therefore a reconciliation is not available without unreasonable effort.

Non-GAAP Measure Definitions: EBITDA is defined as net income (loss) adjusted to eliminate the impact of interest, income taxes, depreciation and amortization. Adjusted EBITDA is defined as EBITDA as further adjusted with certain items management does not consider in assessing ongoing performance. Management uses adjusted EBITDA to set targets and to assess the performance of the Company. Adjusted EBITDA per deployed fleet is defined as (i) adjusted EBITDA for a given quarter, (ii) divided by number of fleets deployed. Annualized adjusted EBITDA per deployed fleet is defined as (i) Adjusted EBITDA per deployed fleet for a given quarter (ii) multiplied by four quarters. Adjusted gross profit is defined as revenue less cost of services, further adjusted to eliminate items in cost of services that management does not consider in assessing ongoing performance. Adjusted net income (loss) is defined as net income (loss) adjusted with certain items management does not consider in assessing ongoing performance. Adjusted net income (loss) per share is defined as (i) adjusted net income, (ii) divided by the number of weighted average shares outstanding. Free cash flow is defined as the net increase (decrease) in cash and cash equivalents before financing activities, excluding any acquisitions. When presenting free cash flow conversion on a historical basis we define it as (i) free cash flow, (ii) divided by adjusted EBITDA; when presenting free cash flow conversion on a forward-looking basis we define it as (i) free cash flow, (ii) divided by EBITDA.Adjusted SG&A is defined as selling, general and administrative expenses adjusted for severance and business divestiture costs, merger/transaction-related costs, and other non-routine items. Net debt is defined as (i) total debt, net of unamortized debt discount and unamortized deferred financing costs, (ii) subtracting cash and cash equivalents. Invested capital is defined as the sum of (a) long-term operating lease liabilities, less current maturities, (b) plus long-term finance lease liabilities, less current maturities, (c) plus long-term debt, net of unamortized deferred financing cost and unamortized debt discounts, less current maturities (d) plus total stockholder’s equity. Average invested capital is defined as the average of the beginning and ending invested capital. Return on invested capital is defined as (i) net income (loss), (ii) divided by average invested capital during the period. Annualized return on invested capital is defined as (i) net income (loss) for a given quarter, (ii) multiplied by four, (iii) divided by average invested capital during the period. Total capital is defined as the sum of (i) total debt, finance leases, operating leases, and total stockholders’ equity. Average total capital is defined as the average of the beginning and ending total capital. Return on total capital is defined as (i) revenue less the (ii) sum of (a) cost of services, (b) depreciation and amortization, and (c) selling, general and administrative expenses (iii) divided by average total capital.
