Merger Update

C&J and Keane completed its previously announced merger on October 31, 2019, creating an industry-leading U.S. land completions provider called NexTier Oilfield Solutions Inc. NexTier’s common stock began trading on the New York Stock Exchange under the ticker symbol “NEX” on October 31, 2019.

“We are excited to complete our merger as planned, creating an industry-leading U.S. land completions provider,” said Robert Drummond. “I appreciate the tremendous efforts made by our collective team to achieve this milestone, and look forward to achieving continued success as NexTier. Our leadership team is laser focused on executing across NexTier’s four points of distinction, including our commitment to partnerships, safety, efficiency, and innovation.”

Synergy Update

The Company previously announced its expectation to achieve $100 million of run-rate cost synergies within one year of closing. NexTier now expects to realize $125 million of run-rate cost synergies by the end of the second quarter of 2020.

“The upsize in magnitude and acceleration in timing of our synergy commitment reflects the complementary nature of our asset base and deep experience in integration planning and execution,” said Greg Powell, Executive Vice President and Chief Integration Officer of NexTier. “Our robust integration planning process has revealed additional opportunities, and we remain highly confident in our ability to achieve our targets, while ensuring strong customer execution.”

Asset Portfolio Update

On a combined basis at closing, NexTier owned a combined fleet of approximately 2.3 million horsepower, representing 50 total hydraulic fracturing fleets. NexTier conducted a thorough review of its joint asset base as part of the Company’s integration planning. As a result of synchronizing horsepower definitions across companies, establishing fleet configurations to account for increasing job intensity, and removing assets from service, the Company has effectively reduced its marketed hydraulic fracturing asset base to 2.2 million horsepower, representing 45 total hydraulic fracturing fleets. Separately, the Company has made a number of asset retirements across its other service areas, including wireline, coiled tubing, cementing, and well services.

“We are happy to contribute to industry capacity rationalization through a sizable reduction in our effective marketed asset base,” said Robert Drummond. “As a result, our asset portfolio is even better positioned to deliver leading safety, efficiency and service quality for customers.”

Balance Sheet and Capital

Pro-forma total debt as of September 30, 2019 was approximately $338 million, net of unamortized debt discounts and unamortized deferred charges and excluding lease obligations. Pro-forma cash and equivalents as of September 30, 2019 was approximately $335 million, resulting in pro-forma net debt of approximately $3 million.

Concurrent with the closing of the merger, NexTier expanded its asset based revolving credit facility from $300 million to $450 million. Total pro-forma liquidity as of September 30, 2019 was $712 million, which includes $335 million in cash and $377 million of availability under our expanded asset based credit facility.

Guidance and Outlook

2

NexTier’s total revenue for the fourth quarter of 2019, covering the three months ended December 31, 2019, is expected to range between $600 million and $650 million, including between $310 million and $340 million for legacy Keane, and between $290 million and $310 million for legacy C&J. Adjusted EBTDA for the fourth quarter of 2019 is expected to range between $60 million and $75 million, including between $50 million and $60 million for legacy Keane operations, and between $10 million and $15 million for legacy C&J operations. The reduction relative to the third quarter of 2019 is primarily driven by lower utilization, mainly due to customer budget exhaustion and seasonality, as well as continued competitive pricing.

“Market conditions for U.S. completions will be challenging during the fourth quarter, driven by E&P budget exhaustion and seasonality,” said Jan Kees van Gaalen, Executive Vice President and Chief Financial Officer of NexTier. “Regardless of the industry backdrop, NexTier is uniquely positioned to deliver value to all stakeholders, supported by leading safety and service quality, profitability, balance sheet strength, and a commitment to further investment in innovation.”

Definitions of Non-GAAP Financial Measures and Other Items

The Company has included both financial measures compiled in accordance with GAAP and certain non-GAAP financial measures in this press release, including Adjusted EBITDA and Adjusted Gross Profit and ratios based on these financial measures. These measurements provide supplemental information which the Company believes is useful to analysts and investors to evaluate its ongoing results of operations, when considered alongside GAAP measures such as net income and operating income. 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 Adjusted EBITDA and Adjusted Gross Profit provide helpful information to analysts and investors to facilitate a comparison of its operating performance to that of other companies.

Adjusted EBITDA is defined as net income (loss) adjusted to eliminate the impact of interest, income taxes, depreciation and amortization, along with certain items management does not consider in assessing ongoing performance. 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.
