Exterran Corporation Announces Third Quarter 2017 Results

Strong Quarterly Results Highlighted by Higher Gross Margins in Oil and Gas Products, Growth in Aftermarket Services, Stable Contract Operations

HOUSTON, November 6, 2017 - Exterran Corporation (NYSE: EXTN) (“Exterran” or the “Company”) today announced net income from continuing operations for the third quarter of 2017 of $3.4 million, or $0.09 per share, on revenue of $327.1 million. This compares to net income from continuing operations of $3.6 million, or $0.10 per share, on revenue of $330.6 million for the second quarter of 2017 and net loss from continuing operations of $32.3 million, or $0.93 per share, on revenue of $229.2 million for the third quarter of 2016.

Andrew Way, Exterran’s President and Chief Executive Officer commented, “We are very pleased to once again report strong quarterly results. Our team did a tremendous job delivering solid results in the face of personal and operational disruptions caused by Hurricane Harvey. We executed well and maintained our focus while delivering our highest gross margin percentage in the oil and gas product sales segment in seven quarters. We are benefiting from efficiency gains in engineering and manufacturing as well as improved supply chain management.

“Our ongoing focus on cash and working capital management are also apparent. We continue to improve our cash and working capital conversion metrics, as our cash balance increased from $45 million at June 30, 2017 to $71 million at September 30, 2017, while our long-term debt remained virtually unchanged.

“Third quarter oil and gas products bookings of $245 million resulted in a strong book-to-bill ratio of nearly 130%. Additionally, we believe oil and gas product gross margins continue to improve moving forward.”

Net income for the third quarter of 2017 was $3.4 million. This compares to net income of $3.5 million for the second quarter of 2017 and a net loss of $12.7 million for the third quarter of 2016.

EBITDA, as adjusted, was $47.1 million for the third quarter of 2017, as compared with EBITDA, as adjusted, of $45.7 million for the second quarter of 2017 and $38.0 million for the third quarter of 2016. See table below for reconciliation of GAAP to non-GAAP financial information.

Selling, general and administrative expenses were $44.2 million in the third quarter of 2017, as compared with $46.1 million in the second quarter of 2017 and $37.9 million in the third quarter of 2016.

Contract Operations Segment

Contract operations revenue in the third quarter of 2017 was $92.6 million, a 3% decrease from second quarter 2017 revenue of $95.3 million and a 7% decrease from third quarter 2016 revenue of $99.1 million.

Contract operations gross margin in the third quarter of 2017 was $58.9 million, a 3% decrease from second quarter 2017 gross margin of $60.7 million and a 7% decrease from third quarter 2016 gross margin of $63.1 million. Gross margin percentage in the third quarter of 2017 was 64%, as compared with 64% in the second quarter of 2017 and 64% in the third quarter of 2016.

The sequential revenue and gross margin decrease was primarily due to renegotiations on a contract extension in Latin America and contractual recoveries in the Middle East benefiting second quarter 2017 results that did not repeat in the third quarter.

Aftermarket Services Segment

Aftermarket services revenue in the third quarter of 2017 was $29.8 million, a 23% increase from second quarter 2017 revenue of $24.2 million and a 12% increase from third quarter 2016 revenue of $26.6 million.

Aftermarket services gross margin in the third quarter of 2017 was $7.9 million, a 13% increase from second quarter 2017 gross margin of $7.0 million and a 5% increase from third quarter 2016 gross margin of $7.5 million. Gross margin percentage in the third quarter of 2017 was 26%, as compared with 29% in the second quarter of 2017 and 28% in the third quarter of 2016.

The sequential increase in aftermarket service revenue and gross margin was primarily due to an increase in Eastern Hemisphere parts sales and an increase in service work in Latin America. The sequential decrease in gross margin percentage was driven primarily by business mix.

Oil and Gas Product Sales Segment

Oil and gas product sales revenue in the third quarter of 2017 was $192.1 million, a 3% decrease from second quarter 2017 revenue of $198.1 million, and a 161% increase from third quarter 2016 revenue of $73.7 million.

Oil and gas product sales gross margin in the third quarter of 2017 was $20.5 million, a 2% increase from second quarter 2017 gross margin of $20.1 million and a 468% increase from third quarter 2016 gross margin of $3.6 million. Gross margin percentage in the third quarter of 2017 was 11% as compared with 10% in the second quarter of 2017 and 5% in the third quarter of 2016.

The sequential decrease in revenue was attributable to production downtime associated with Hurricane Harvey, as both of the Company’s Houston manufacturing facilities were closed for more than a week due to the catastrophic flooding in the Houston area. Sequential gross margin and gross margin percentage were higher due to productivity and product mix.

Oil and gas product sales backlog was $559.9 million at September 30, 2017, as compared to $506.5 million at June 30, 2017 and $153.1 million at September 30, 2016. Oil and gas product sales bookings for the third quarter of 2017 were $245.5 million. This compares to bookings of $280.1 million for the second quarter of 2017 and bookings of $132.3 million for the third quarter of 2016.

Belleli EPC Product Sales Segment

As previously disclosed, the Company is in the process of exiting the non-core business lines of Belleli EPC. Third quarter 2017 revenue was $12.6 million and gross margin was $3.5 million. Results for the quarter were positively impacted by improved operational execution.

Non-GAAP 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.

⁽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 provide 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 (restricted stock and certain of our stock settled 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, 2017 from our calculation of diluted adjusted net income (loss) from continuing operations per common share.
