NUVERRA ANNOUNCES FOURTH QUARTER AND FULL YEAR 2018 RESULTS

- Q4 2018 revenue up 6% over the prior year driven by increased business activity and improved pricing -

- Company achieves 2018 full year revenue growth of 12% -

SCOTTSDALE, AZ (March 11, 2019) - Nuverra Environmental Solutions, Inc. (NYSE American: NES) (“Nuverra” or the “Company”) today announced financial and operating results for the fourth quarter and full year ended December 31, 2018.

SUMMARY OF FINANCIAL RESULTS

• Fourth quarter revenue was $49.2 million, a decrease of approximately 0.9%, or $0.5 million, when compared to the third quarter of 2018 which was primarily due to lower activity levels at the end of the year due to the holidays.

• When compared to the same period in the prior year, fourth quarter revenue increased 6.0%, or $2.8 million, as a result of increases in both activity and pricing and the acquisition of Clearwater Solutions on October 5, 2018. These increases were offset by a decrease in revenue during the fourth quarter due to the exit of the Eagle Ford shale area in the first quarter of 2018.

• Full year 2018 revenue was $197.5 million, an increase of $21.4 million, or 12.2%, when compared with $176.1 million for 2017. The increase was primarily due to a 14.4% improvement in activity and a 2.8% improvement in pricing, offset by a decrease in revenue due to the exit of the Eagle Ford shale area.

• Net loss for the fourth quarter was $8.8 million as compared to $7.1 million in the third quarter of 2018 and $30.9 million in the fourth quarter of 2017.

• Adjusted EBITDA for the fourth quarter was $6.1 million, an increase of 55.0% when compared with the $3.9 million reported in the third quarter of 2018. The acquisition of Clearwater Solutions represented $1.7 million of the increase, with the remaining increase attributable to increases in pricing, offset by decreases in activity.

• Fourth quarter 2018 adjusted EBITDA increased by $1.0 million, or 18.6%, over the same period in the prior year which was mainly driven by the Clearwater Solutions acquisition, offset by a decrease in activity.

• Total liquidity available for capital spending and other purposes of $25.5 million as of December 31, 2018.

“Nuverra enjoyed a stronger operating environment in 2018, reflecting increased activity and selected pricing improvement,” said Charlie Thompson, Chief Executive Officer. “Revenue and adjusted EBITDA increased meaningfully year over year. 2018 was a year of transition as we made management, business process and technology changes, the benefits of which we hope to see throughout 2019. We acquired three disposal wells in the Northeast region that better positions us to serve customers in that market, and we invested in 28 new trucks that will be in service by the end of the second quarter. We exited the year with a healthy leverage and liquidity position and hope to continue improving the business throughout 2019.”

FOURTH QUARTER 2018 RESULTS

Fourth quarter revenue was $49.2 million, a decrease of approximately 0.9%, or $0.5 million, when compared to the third quarter of 2018 which was primarily due to lower activity levels at the end of the year due to the holidays. When compared to the fourth quarter of 2017, fourth quarter revenue increased by $2.8 million, or 6.0%, as a result of increases in both activity and pricing and the acquisition of Clearwater Solutions on October 5, 2018. These increases were offset by a decrease in revenue during the fourth quarter due to the exit of the Eagle Ford shale area in the first quarter of 2018.

Total costs and expenses for the fourth quarter were $55.7 million. Total costs and expenses, adjusted for special items, were $52.9 million, or a $3.0 million decrease when compared with $55.9 million in the third quarter of 2018 due primarily to lower direct operating expenses as we were able to hire and retain more full time drivers versus using higher cost third party drivers. Total costs and expenses, adjusted for special items, decreased 15.0% compared with $62.3 million in the fourth quarter of 2017, driven primarily by lower depreciation expense.

Net loss for the fourth quarter was $8.8 million as compared to $7.1 million in the third quarter of 2018 and $30.9 million in the fourth quarter of 2017. For the fourth quarter of 2018, the Company reported a net loss, adjusted for special items, of $6.0

1

million. Special items in the fourth quarter primarily included the loss on the sale of underutilized assets, non-recurring legal and professional fees, stock-based compensation expense, $0.8 million in transaction costs incurred in connection with the Clearwater Solutions acquisition, $0.4 million in severance for the departure of the former CFO, as well as $0.3 million in long-lived asset impairment charges for assets held for sale in the Southern division. This compares with a net loss, adjusted for special items, of $7.4 million in the third quarter of 2018 and $17.3 million in the fourth quarter of 2017.

Adjusted EBITDA for the fourth quarter was $6.1 million, an increase of $2.2 million, or 55.0%, when compared with the third quarter of 2018. The acquisition of Clearwater Solutions represented $1.7 million of the increase, with the remaining increase attributable to increases in pricing, offset by decreases in activity. Fourth quarter adjusted EBITDA margin was 12.4%, compared with 7.9% in the third quarter of 2018. When compared with the fourth quarter of 2017, adjusted EBITDA increased by $1.0 million, or 18.6%, which was mainly driven by the Clearwater Solutions acquisition, offset by a decrease in activity. Fourth quarter adjusted EBITDA margin was 12.4%, compared with 11.1% in the fourth quarter of 2017.

FULL YEAR 2018 RESULTS

Revenue for the full year was $197.5 million, an increase of $21.4 million, or 12.2%, when compared with $176.1 million for 2017. Revenue growth was driven primarily by a 14.4% increase in activity levels including water transfer services in the Rocky Mountain and Northeast divisions, offset by a decrease in activity levels for water transfer services, including our permanent disposal water pipeline, in the Southern division. Pricing increases in all divisions also contributed to 2.8% of the increase in revenue during the current year. Offsetting the higher activity levels and price increases was the exit of the Eagle Ford shale area in the first quarter of 2018 which represented approximately 5.0% of the decline in revenues as compared to 2017.

Net loss for the full year was $59.3 million. When adjusted for special items, net loss for the full year was $36.0 million, compared with a net loss, adjusted for special items, of $79.6 million in 2017. 2018 special items primarily included $15.3 million in severance and stock-based compensation expense related to the departure of the former CEO and CFO, $4.8 million in long-lived asset impairment charges for assets held for sale in the Southern, Northeast and Corporate divisions, $1.3 million in transaction costs related to the acquisition of Clearwater Solutions, $1.1 million of exit costs related to management’s decision to exit the Eagle Ford shale area, $1.7 million of capital reorganization costs incurred after the chapter 11 filing recorded to “Reorganization items, net,” and non-routine litigation expenses and non-routine professional fees.

Adjusted EBITDA for the full year was $16.5 million, an increase of 24.1% when compared with $13.3 million in 2017. Pricing increases and the Clearwater Solutions acquisition drove the majority of the increase. Adjusted EBITDA margin for 2018 was 8.4%, compared with 7.6% in 2017.

CASH FLOW AND LIQUIDITY

Net cash provided by operating activities for the full year ended December 31, 2018 was $9.4 million, while asset sales net of capital expenditures provided proceeds of $6.9 million. Free cash flow, defined as cash from operations less net cash capital expenditures, totaled $16.3 million for 2018, up from negative $23.7 million in 2017. Asset sales were related to unused or underutilized assets and the proceeds are expected to continue to be reinvested in returns-driven growth projects during 2019, including the planned purchase of new water transfer trucks for our fleet. Capital expenditures in 2018 primarily consisted of new water transfer trucks in the Northeast division, new water transfer equipment in the Rocky Mountain division, as well as expenditures to extend the useful life and productivity on our existing fleet of trucks, tanks, equipment and disposal wells.

Total liquidity available for capital spending and other purposes as of December 31, 2018 was $25.5 million. This consisted of cash and restricted cash of $8.0 million, $11.8 million of net availability under the revolving facility and $5.7 million available as a delayed draw under the second lien term loan facility. As of December 31, 2018, total debt outstanding was $66.4 million, consisting of $21.9 million under our senior secured term loan facility, $10.1 million under our second lien term loan facility, $32.5 million under our bridge term loan, and $1.9 million of capital leases for vehicle financings. On January 2, 2019, we received aggregate gross proceeds of $32.5 million from a rights offering and repaid the bridge term loan in full.

BASIS OF PRESENTATION

As previously disclosed, the Company emerged from chapter 11 bankruptcy on August 7, 2017, or the “Effective Date,” and elected to apply fresh start accounting as of July 31, 2017 to coincide with the timing of the normal accounting period close. References to “Successor” relate to the financial position and results of operations of the reorganized Company subsequent to July 31, 2017, while references to “Predecessor” refer to the financial position and results of operations of the Company on and prior to July 31, 2017. The Successor and Predecessor GAAP results for the applicable periods are presented in the tables following this release.

2

For discussion purposes, the Company has combined the Successor and Predecessor periods to derive combined results for the year ended December 31, 2017. However, because of various adjustments to the condensed consolidated financial statements in connection with the application of fresh start accounting, the results of operations for the Successor period are not comparable to those of the Predecessor period. The Company believes that, subject to consideration of the impact of fresh start accounting, combining the results of the Successor and Predecessor periods provides meaningful information about the financial results of the Company, including revenues and costs that assist a reader in understanding the financial results for the applicable periods.

NON-GAAP RECONCILIATIONS

(In thousands)

(Unaudited)

This press release contains non-GAAP financial measures as defined by the rules and regulations of the United States Securities and Exchange Commission. A non-GAAP financial measure is a numerical measure of a company’s historical or future financial performance, financial position or cash flows that excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the statements of operations or balance sheets of the Company; or includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented. Reconciliations of these non-GAAP financial measures to their comparable GAAP financial measures are included in the attached financial tables.

These non-GAAP financial measures are provided because management of the Company uses these financial measures in evaluating the Company’s ongoing financial results and trends. Management uses this non-GAAP information as an indicator of business results, and evaluates overall performance with respect to such indicators. Management believes that excluding items such as acquisition expenses, amortization of intangible assets, stock-based compensation, asset impairments, restructuring charges, expenses related to litigation and resolution of lawsuits, and other charges, which may or may not be non-recurring, among other items that are inconsistent in amount and frequency (as with acquisition expenses), or determined pursuant to complex formulas that incorporate factors, such as market volatility, that are beyond our control (as with stock-based compensation), for purposes of calculating these non-GAAP financial measures facilitates a more meaningful evaluation of the Company’s current operating performance and comparisons to the past and future operating performance. The Company believes that providing non-GAAP financial measures such as EBITDA, adjusted EBITDA, adjusted net income (loss), and adjusted net income (loss) per share, in addition to related GAAP financial measures, provides investors with greater transparency to the information used by the Company’s management. These non-GAAP financial measures are not substitutes for measures of performance or liquidity calculated in accordance with GAAP and may not necessarily be indicative of the Company’s liquidity or ability to fund cash needs. Not all companies calculate non-GAAP financial measures in the same manner, and our presentation may not be comparable to the presentations of other companies.

For illustrative purposes, the Company has combined the Successor and Predecessor periods to derive combined results for the year ended December 31, 2017 for these non-GAAP reconciliations. The combination was generated by addition of comparable financial statement line item captions. However, because of various adjustments to the condensed consolidated financial statements in connection with the application of fresh start accounting, including asset valuation adjustments and liability adjustments, the results of operations for the Successor period are not comparable to those of the Predecessor period. The financial information preceding these non-GAAP reconciliations provides the Successor and Predecessor GAAP results for the applicable periods. The Company believes that subject to consideration of the impact of fresh start accounting, combining the results of the Successor and Predecessor periods provides meaningful information about the financial results of the Company, including revenues and costs that assist a reader in understanding the financial results for the applicable periods.
