LAYNE CHRISTENSEN REPORTS

FISCAL 2018 FIRST QUARTER RESULTS

THE WOODLANDS, TEXAS, June 8, 2017 – Layne Christensen Company (NASDAQ: LAYN) (“Layne” or the “Company”) today announced financial and operating results for the fiscal 2018 first quarter (Q1 FY 2018) ended April 30, 2017.

Q1 FY 2018 Financial Highlights

CEO Commentary

Michael J. Caliel, President and Chief Executive Officer of Layne, commented, “We are encouraged with the significant financial improvement we delivered in the first quarter that was led by continuing strength at Inliner, further reductions in SG&A costs, and significantly improved activity and profitability at Mineral Services.  Further, the improvements underway at Water Resources to stem project losses we incurred in the last half of fiscal year 2017 led to meaningful sequential improvement for the division.

“The completion of the sale of our Heavy Civil business will allow us to concentrate on growing our core water infrastructure businesses, while reducing our overall risk exposure to large construction projects.  

“We are pleased and excited about our new energy infrastructure business and the construction of our new high-capacity water pipeline and infrastructure system in the Delaware Basin of West Texas.  This investment is part of our longer-term strategy to leverage our substantial know-how in providing water infrastructure solutions to our clients and is expected to build on our core water and energy expertise, and broaden our diverse water customer base.

“Our objectives for fiscal 2018 are to significantly improve profitability at Water Resources, leverage our strengths at Inliner to further grow the business, take advantage of the improved levels of activity in the Americas for Minerals Services, further reduce our cost base and significantly grow our energy infrastructure business. While clearly there is more work to be done, we expect our overall financial performance in fiscal 2018 to show material improvement over last fiscal year and are confident that our efforts will be successful.”

Summary of Operating Segment Data

The following table summarizes financial information for Layne's operating segments. A discussion of the results for Q1 FY 2018 for each segment compared to the prior year period follows the table.

Water Resources

Revenues for Water Resources decreased during Q1 FY 2018 primarily due to reduced activity in agricultural drilling projects in the western U.S. stemming from increased precipitation in the region.  

The decrease in Adjusted EBITDA for the Water Resources segment for Q1 FY 2018 was primarily due to reduced drilling activity in the western U.S.

Backlog was $62.3 million at April 30, 2017 compared to $49.2 million at January 31, 2017 and $91.7 million at April 30, 2016.  Backlog increased from Q4 FY 2017 to Q1 FY 2018 as a result of increased bookings in both water well drilling and repair and maintenance work.  

Inliner

Revenues for Inliner during Q1 FY 2018 were relatively flat as compared to the prior year period.

4

The increase in Adjusted EBITDA for the Inliner segment as compared to the prior year period reflects improved results across most operating regions.  The increase in Adjusted EBITDA for the Inliner segment as a percentage of revenues was primarily attributable to a higher mix of self-performed work and increased crew efficiency in the current quarter compared to the prior year period.

Backlog was $109.9 million at April 30, 2017 compared to $117.4 million at January 31, 2017 and $121.8 million at April 30, 2016.

Mineral Services

Revenues for Mineral Services were almost double the prior year period due to increased activity in the western U.S., Mexico and Brazil.

The increase in Adjusted EBITDA for the Mineral Services segment for Q1 FY 2018 was primarily due to significantly increased activity and profitability in the western U.S. and Mexico, compared to the prior year period.

Unallocated Corporate Expenses

Unallocated corporate expenses reflected in Adjusted EBITDA were $4.0 million for the Q1 FY 2018, compared to $7.0 million for the same period last year. The improvement was primarily due to a reduction in legal and professional fees, consulting fees and compensation related expenses.

Use of Non-GAAP Financial Information

Layne defines Total Adjusted EBITDA, a non-GAAP financial measure, as the total of Adjusted EBITDA for all segments plus unallocated corporate expenses and other items/eliminations.  Layne’s management evaluates segment performance based primarily on the segment’s revenues and Adjusted EBITDA, among other factors.  Layne’s measure of segment Adjusted EBITDA, which may not be comparable to other companies’ measure of Adjusted EBITDA, represents the segment’s shares of income or loss from continuing operations before interest, taxes, depreciation and amortization, gain on sale of fixed assets, non-cash share-based compensation, equity in earnings or losses from affiliates, certain non-recurring items such as restructuring costs, and certain other gains or losses, plus dividends received from affiliates. Total Adjusted EBITDA is included as a complement to results provided in accordance with generally accepted accounting principles (GAAP) because management believes this non-GAAP financial measure helps us understand and evaluate our operating performance and trends and provides useful information to both management and investors.  In addition, we use Total Adjusted EBITDA as a factor in incentive compensation decisions and our credit facility agreement uses measures similar to Total Adjusted EBITDA to measure compliance with certain covenants.

The following table reconciles Total Adjusted EBITDA to income (loss) from continuing operations before income taxes, which Layne consider to be the most directly comparable GAAP financial measure to Total Adjusted EBITDA.
