Exterran Corporation Announces First Quarter 2019 Results

Operating Results In-Line with Expectations

Strong Operating Cash Flow

Bought Back 268,500 Shares during the Quarter

HOUSTON, May 1, 2019 - Exterran Corporation (NYSE: EXTN) (“Exterran” or the “Company”) today reported first quarter financial results.

Andrew Way, Exterran’s President and Chief Executive Officer commented, “We continue to execute well on our product sales and ECO backlog and results for the quarter were as expected, including generating $49 million in operating cash flow. Product sales orders were $86 million, including roughly $25 million in our water business, and we remain positive regarding future demand.

“Under the current authorization we repurchased 268,500 shares at an average price of $17.35 per share during the open period in March. Since the spin we have focused on generating cash flow, paying down debt, investing in the business and improving returns. Today we feel the stock value is extremely attractive and plan to use the share buyback authority aggressively going forward.”

Net loss from continuing operations was $5.6 million, or $0.16 per share, on revenue of $351.4 million for the first quarter of 2019. This compares to net loss from continuing operations of $5.3 million, or $0.15 per share, on revenue of $332.2 million for the fourth quarter of 2018 and net income from continuing operations of $3.9 million, or $0.11 per share, on revenue of $350.4 million for the first quarter of 2018. Net loss was $5.4 million for the first quarter of 2019, as compared to net income of $14.1 million for the fourth quarter of 2018 and net income of $5.3 million for the first quarter of 2018. EBITDA, as adjusted, was $50.2 million for the first quarter of 2019, as compared to $51.5 million for the fourth quarter of 2018 and $50.7 million for the first quarter of 2018. Income before taxes was $3.6 million as compared to $11.1 million for the fourth quarter of 2018 and $9.4 million for the first quarter of 2018.

Selling, general and administrative expenses were $43.5 million in the first quarter of 2019, as compared with $44.7 million in the fourth quarter of 2018 and $44.2 million in the first quarter of 2018.

Contract Operations Segment

Contract operations revenue in the first quarter of 2019 was $85.7 million, a 3% decrease from fourth quarter of 2018 revenue of $88.2 million and an 11% decrease from first quarter of 2018 revenue of $96.5 million.

Contract operations gross margin in the first quarter of 2019 was $57.1 million, as compared to gross margin of $61.6 million in the fourth quarter of 2018 and $61.1 million in the first quarter of 2018. Gross margin percentage in the first quarter of 2019 was 67%, as compared with 70% in the fourth quarter of 2018 and 63% in the first quarter of 2018.

Revenue declined sequentially given the impact of commercial negotiations in the fourth quarter of 2018 that did not reoccur. The year over year revenue decline was largely driven by the impact of foreign currency exchange of about $8 million along with stops in the normal course of business.

Aftermarket Services Segment

Aftermarket services revenue in the first quarter of 2019 was $27.3 million, a 15% decrease from fourth quarter of 2018 revenue of $32.0 million and a 4% increase from first quarter of 2018 revenue of $26.4 million.

Aftermarket services gross margin in the first quarter of 2019 was $6.6 million, an 8% decrease from the fourth quarter of 2018 gross margin of $7.1 million and a 12% decrease from the first quarter of 2018 gross margin of $7.5 million. Gross margin percentage in the first quarter of 2019 was 24%, as compared with 22% in the fourth quarter of 2018 and 28% in the first quarter of 2018.

The sequential decline in aftermarket service revenue was largely driven by the typical first quarter seasonality in the parts sales side of the business. The year over year impact to margins is tied to a shift in service mix.

Product Sales Segment

Product sales revenue in the first quarter of 2019 was $238.4 million, a 13% increase from fourth quarter of 2018 revenue of $211.9 million, and a 5% increase from first quarter of 2018 revenue of $227.5 million.

Product sales gross margin in the first quarter of 2019 was $28.9 million, a 9% increase from fourth quarter of 2018 gross margin of $26.6 million and a 6% increase as compared to the first quarter of 2018 gross margin of $27.2 million. Gross margin percentage in the first quarter of 2019 was 12%, as compared with 13% in the fourth quarter of 2018 and 12% in the first quarter of 2018.

The revenue increase was driven by strong execution on our products backlog. Gross margins declined slightly as the mix towards compression increased.

Product sales backlog was $553.5 million at March 31, 2019, as compared to $705.8 million at December 31, 2018 and $426.9 million at March 31, 2018. Product sales bookings for the first quarter of 2019 were $86.2 million, resulting in a book-to-bill ratio of 36%. This compares to bookings of $158.6 million for the fourth quarter of 2018 and bookings of $193.4 million for the first quarter of 2018.

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