Exterran Corporation Announces Fourth Quarter and Full Year 2018 Results

Strong Operating Results In-Line with Expectations

Board Authorized $100 million Share Repurchase Program

Over $25 million in commitments for Exterran Water Solutions since November

Contract Operations win in the Middle East/Africa Region

HOUSTON, February 25, 2019 - Exterran Corporation (NYSE: EXTN) (“Exterran” or the “Company”) today reported fourth quarter financial results.

Andrew Way, Exterran’s President and Chief Executive Officer commented, “We are very pleased with our results for the fourth quarter which were consistent with our expectations. Commercially we had a key win in the Middle East/Africa region for a fully integrated cryogenic processing plant. Within our water business we converted our trial from late last year into an ECO contract which builds strong momentum as we enter 2019. We have had over $25 million in commitments within the business both domestically and internationally since our last call. We continue to focus on cash flow and returns which resulted in net cash from operating activities of $153 million for the year.

“Product bookings were $159 million in the fourth quarter up 40% year over year, with full year book to bill of 1.3x providing record year-end backlog.

“Our Board has authorized a $100 million share repurchase program that goes through February 2022. We believe this program provides us another avenue to deploy capital to best drive shareholder value over the long run.”

Net loss from continuing operations was $5.3 million, or $0.15 per share, on revenue of $332.2 million for the fourth quarter of 2018. This compares to net income from continuing operations of $3.2 million, or $0.09 per share, on revenue of $334.8 million for the third quarter of 2018 and net income from continuing operations of $2.1 million, or $0.06 per share, on revenue of $337.7 million for the fourth quarter of 2017. Net income was $14.1 million for the fourth quarter of 2018, as compared to $5.4 million for the third quarter of 2018 and $6.7 million for the fourth quarter of 2017. EBITDA, as adjusted, was $51.5 million for the fourth quarter of 2018, as compared to $52.1 million for the third quarter of 2018 and $50.5 million for the fourth quarter of 2017. Income before income taxes was $11.1 million as compared to income before taxes of $11.2 million for the third quarter of 2018 and $5.2 million for the fourth quarter of 2017.

Selling, general and administrative expenses were $44.7 million in the fourth quarter of 2018, as compared with $45.1 million in the third quarter of 2018 and $44.5 million in the fourth quarter of 2017.

Contract Operations Segment

Contract operations revenue in the fourth quarter of 2018 was $88.2 million, a 4% increase from third quarter 2018 revenue of $84.8 million and an 8% decrease from fourth quarter 2017 revenue of $95.3 million.

Contract operations gross margin in the fourth quarter of 2018 was $61.6 million, as compared to gross margin of $57.1 million in the third quarter of 2018 and $61.1 million in fourth quarter of 2017. Gross margin percentage in the fourth quarter of 2018 was 70%, as compared with 67% in the third quarter of 2018 and 64% in the fourth quarter of 2017. Contract operations backlog at the end of 2018 was $1.4 billion, flat when compared the third quarter 2018.

The margin increase was driven by productivity and commercial negotiations.

Aftermarket Services Segment

Aftermarket services revenue in the fourth quarter of 2018 was $32.0 million, a 7% increase from third quarter 2018 revenue of $30.0 million and a 5% increase from fourth quarter 2017 revenue of $30.5 million.

Aftermarket services gross margin in the fourth quarter of 2018 was $7.1 million, a 9% decrease from third quarter 2018 gross margin of $7.9 million and a 12% decrease from fourth quarter 2017 gross margin of $8.1 million. Gross margin percentage in the fourth quarter of 2018 was 22%, as compared with 26% in the third quarter of 2018 and 26% in the fourth quarter of 2017.

The sequential decline in gross margin was largely driven by an increase in the mix of parts sales.

Product Sales Segment

Product sales revenue in the fourth quarter of 2018 was $211.9 million, a 4% decrease from third quarter 2018 revenue of $220.0 million, and flat from fourth quarter 2017 revenue of $211.9 million.

Product sales gross margin in the fourth quarter of 2018 was $26.6 million, a 16% decrease from third quarter 2018 gross margin of $31.8 million and a 9% increase from fourth quarter 2017 gross margin of $24.5 million. Gross margin percentage in the fourth quarter of 2018 was 13% as compared with 14% in the third quarter of 2018 and 12% in the fourth quarter of 2017.

The decline in revenue for product sales sequentially was largely due to timing of processing and treating orders, along with incremental shop hours committed to contract operations projects. Although compression margins improved during the quarter the mix shift towards compression negatively impacted margin rate.

Product sales backlog was $705.8 million at December 31, 2018, as compared to $759.1 million at September 30, 2018 and $461.0 million at December 31, 2017. Product sales bookings for the fourth quarter of 2018 were $158.6 million, resulting in a book-to-bill ratio of 75%. This compares to bookings of $344.1 million for the third quarter of 2018 and bookings of $113.0 million for the fourth quarter of 2017.

⁽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 and $0.2 million for the three months ended September 30, 2018 and year ended December 31, 2018, respectively, from our calculation of diluted adjusted net income (loss) from continuing operations per common share.
