Exterran Corporation Announces Third Quarter 2018 Results

Productivity Creates Strong Operating Results

Continued Focus on Working Capital Drives Operating Cash Flow

Record Products Backlog

HOUSTON, November 5, 2018 - Exterran Corporation (NYSE: EXTN) (“Exterran” or the “Company”) today reported third quarter financial results.

Andrew Way, Exterran’s President and Chief Executive Officer commented, “We are extremely pleased with our results for the third quarter, which were in-line with our expectations. Despite reports of transitory issues in the Permian, our business has remained resilient as the order activity is set for operations in late 2019 and beyond. Our Exterran Water Solution had a successful pilot with a large E&P operator providing us momentum as we head into 2019. We continued to focus on cash flow and returns that resulted in net cash from operating activities of $61 million, which fully funded our growth CAPEX.

“Product bookings of $344 million provided us a book to bill over 1.5x, as midstream companies continue to prepare for increased pipeline capacity coming into service in the second half of 2019 and beyond. Last quarter, we discussed a Middle East product order that may convert to a contract operations deal. The customer has elected to keep the award as a product sale, resulting in a product sales backlog of $759 million as of September 30, 2018. Contract operations backlog as of September 30, 2018 remained flat at $1.4 billion when compared to the prior quarter.”

Net income from continuing operations was $3.2 million, or $0.09 per share, on revenue of $334.8 million for the third quarter of 2018. This compares to net loss from continuing operations of $1.5 million, or $0.04 per share, on revenue of $343.5 million for the second quarter of 2018 and net income from continuing operations of $1.2 million, or $0.03 per share, on revenue of $314.5 million for the third quarter of 2017. EBITDA, as adjusted, was $52.1 million for the third quarter of 2018, as compared to $51.2 million for the second quarter of 2018 and $44.8 million for the third quarter of 2017. Income before taxes was $11.2 million as compared to $8.2 million for the second quarter of 2018 and $9.6 million a year ago.

Selling, general and administrative expenses were $45.1 million in the third quarter of 2018, as compared with $44.4 million in the second quarter of 2018 and $42.9 million in the third quarter of 2017.

Contract Operations Segment

Contract operations revenue in the third quarter of 2018 was $84.8 million, a 7% decrease from second quarter of 2018 revenue of $91.5 million and an 8% decrease from third quarter of 2017 revenue of $92.6 million.

Contract operations gross margin in the third quarter of 2018 was $57.1 million, as compared to gross margin of $59.1 million in the second quarter of 2018 and $58.9 million in the third quarter of 2017. Gross margin percentage in the third quarter of 2018 was 67%, as compared with 65% in the second quarter of 2018 and 64% in the third quarter of 2017.

The sequential revenue decline was primarily due to exchange rate impact on sales in Argentina and quarter over quarter change in contract recoveries.

Aftermarket Services Segment

Aftermarket services revenue in the third quarter of 2018 was $30.0 million, a 7% decrease from second quarter of 2018 revenue of $32.3 million and a 1% increase from third quarter of 2017 revenue of $29.8 million.

Aftermarket services gross margin in the third quarter of 2018 was $7.9 million, an 8% decrease from the second quarter of 2018 gross margin of $8.6 million and a 1% decrease from the third quarter of 2017 gross margin of $7.9 million. Gross margin percentage in the third quarter of 2018 was 26%, as compared with 27% in the second quarter of 2018 and 26% in the third quarter of 2017.

The sequential decline in aftermarket service revenue was driven primarily by decreases in commissioning services and operation and maintenance services.

Product Sales Segment

Product sales revenue in the third quarter of 2018 was $220.0 million, relatively flat with the second quarter of 2018 revenue of $219.7 million, and a 15% increase from third quarter of 2017 revenue of $192.1 million.

Product sales gross margin in the third quarter of 2018 was $31.8 million, a 14% increase from second quarter of 2018 gross margin of $28.0 million and a 55% increase as compared to the third quarter of 2017 gross margin of $20.5 million. Gross margin percentage in the third quarter of 2018 was 14%, as compared with 13% in the second quarter of 2018 and 11% in the third quarter of 2017.

The revenue was flat sequentially primarily due to increased allocation of hours to our contract operations and mix aligned to longer-cycle products.

Product sales backlog was $759.1 million at September 30, 2018, as compared to $634.9 million at June 30, 2018 and $559.9 million at September 30, 2017. Product sales bookings for the third quarter of 2018 were $344.1 million, resulting in a book-to-bill ratio of 156%. This compares to bookings of $439.7 million for the second quarter of 2018 and bookings of $245.5 million for the third quarter of 2017.

Non-GAAP and Other Financial Information

Gross Margin is defined as revenue less cost of sales (excluding depreciation and amortization expense). Gross margin percentage is defined as gross margin divided by revenue. The Company evaluates the performance of its segments based on gross margin for each segment.

EBITDA, as adjusted, a non-GAAP measure, is defined as net income (loss) excluding income (loss) from discontinued operations (net of tax), cumulative effect of accounting changes (net of tax), income taxes, interest expense (including debt extinguishment costs), depreciation and amortization expense, impairment charges, restructuring and other charges, non-cash gains or losses from foreign currency exchange rate changes recorded on intercompany obligations, expensed acquisition costs and other items. EBITDA, as adjusted, excludes the benefit of the two previously announced sales of our Venezuelan assets.

Adjusted net income (loss) from continuing operations and diluted adjusted net income (loss) from continuing operations per common share, non-GAAP measures, are defined as net income (loss) and earnings per share, excluding the impact of income (loss) from discontinued operations (net of tax), cumulative effect of accounting changes (net of tax), impairment charges (net of tax), restructuring and other charges (net of tax), the benefit of the previously announced sale of our joint ventures’ Venezuelan assets, the effect of income tax adjustments that are outside of the Company’s anticipated effective tax rates and other items.

See tables below for additional information concerning non-GAAP financial information, including a reconciliation of the non-GAAP financial information presented in this press release to the most directly comparable financial information presented in accordance with GAAP. Non-GAAP financial information supplements should be read together with, and are not an alternative or substitute for, the Company’s financial results reported in accordance with GAAP. Because non-GAAP financial information is not standardized, it may not be possible to compare these financial measures with other companies’ non-GAAP financial measures having the same or similar names.

⁽¹⁾Management evaluates the performance of each of the Company’s segments based on gross margin. Total gross margin, a non-GAAP measure, is included as a supplemental disclosure because it is a primary measure used by our management to evaluate the results of revenue and cost of sales (excluding depreciation and amortization expense), which are key components of our operations. Management believes total gross margin is important supplemental information for investors because it focuses on the current 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, the indirect costs associated with our SG&A activities, the impact of our financing methods, restatement related charges (recoveries), restructuring and other charges and income taxes. In addition, the inclusion of depreciation and amortization expense may not accurately reflect the costs required to maintain and replenish the operational usage of our assets and therefore may not portray the costs from current operating activity.

⁽²⁾Management believes EBITDA, as adjusted, is an important measure of operating performance because it allows management, investors and others to evaluate and compare our core operating results from period to period by removing the impact of our capital structure (interest expense from outstanding debt), asset base (depreciation and amortization), our subsidiaries’ capital structure (non-cash gains or losses from foreign currency exchange rate changes on intercompany obligations), tax consequences, impairment charges, restatement related charges (recoveries), restructuring and other charges, expensed acquisition costs and other items. Management uses EBITDA, as adjusted, as supplemental measures to review current period operating performance, comparability measures and performance measures for period to period comparisons. In addition, the Company's compensation committee has used EBITDA, as adjusted, in evaluating the performance of the Company and management and in evaluating certain components of executive compensation, including performance-based annual incentive programs.

⁽³⁾The tax impacts of adjustments were based on the Company’s statutory tax rates applicable to each item in the appropriate taxing jurisdictions. Using statutory tax rates for presentation of the non-GAAP measures allows a consistent basis for investors to understand financial performance of the Company across historical periods. The overall effective tax rate on adjustments was impacted by the inability to recognize tax benefits from charges in jurisdictions that are in cumulative-loss positions.

⁽⁴⁾Management believes adjusted net income (loss) from continuing operations and diluted adjusted net income (loss) from continuing operations per common share provides useful information to investors because it allows management, investors and others to evaluate and compare our core operating results from period to period by removing the impact of impairment charges, restructuring and other charges, restatement related charges (recoveries), expensed acquisition costs and other items not appropriately reflective of our core business.

⁽⁵⁾ Diluted adjusted net income (loss) from continuing operations per common share, was computed using the two-class method to determine the net income (loss) per share for each class of common stock and participating security (certain of our restricted stock and restricted stock units) according to participation rights in undistributed earnings. Accordingly, we have excluded adjusted net income from continuing operations attributable to participating securities of $0.1 million for the three months ended September 30, 2018 from our calculation of diluted adjusted net income (loss) from continuing operations per common share.
