Subject Company: Layne Christensen Company

Commission File No.: 001-34195

Date: March 7, 2018

On March 7, 2018, Layne Christensen Company sent the following communication on behalf of its Chief Executive Officer to its employees regarding the proposed combination with Granite Construction Incorporated.

Two weeks ago, I shared with you what I believe to be the most exciting and transformative announcement in Layne’s 135-year history: the agreement to combine our company with Granite Construction. While this move is the right thing for our company, our customers, and, most importantly, our people, we must remember that for now, Layne and Granite are two separate companies, and it’s business as usual here at Layne. Until this transaction closes, which we expect to happen in the second quarter of this year, we must continue to execute our business plans and strategy. During the next few months, it’s more important than ever to keep our people safe and deliver the same high-quality service our customers expect from Layne.

Over the past week, some of you had the opportunity to meet Granite CEO Jim Roberts when he visited our headquarters in The Woodlands, Texas, and our Inliner office in Orleans, Indiana. These introductions are the first steps in the process of integrating our two organizations. Teams from Granite and Layne are working together to develop the integration plan and timeline. The Layne integration team, composed of senior divisional and functional leaders from around our company, held its kickoff meeting with its Granite counterparts earlier this week, and meetings between the two teams will continue on an ongoing basis as we move toward combining our companies.

As the integration plan takes shape and more information becomes available, we will keep you updated through Fast Layne, updates on LBC, and Laynecasts. I am committed to ensuring that everyone knows what’s happening with our company during this important integration period. As always, if you have any questions, you can reach me directly at (+1) 281-475-2690 or via email at AskMike@layne.com.

These forward-looking statements involve certain risks and uncertainties that could cause actual results to differ materially from those indicated in such forward-looking statements, including but not limited to: failure to obtain applicable regulatory or stockholder approvals in a timely manner or otherwise; failure to satisfy other closing conditions to the merger; risks that Layne will not be integrated successfully or that Granite will not realize estimated cost savings, synergies and growth or that such benefits may take longer to realize than expected; failure to realize anticipated benefits from Layne’s operations; risks relating to unanticipated costs of integration; reductions in customer spending, or a slowdown in customer payments; unanticipated changes relating to competitive factors in the industry in which Layne and Granite participate; ability to hire and retain key personnel; ability to successfully integrate Layne’s businesses; the potential impact of announcement or consummation of the merger on relationships with third parties, including customers, employees and competitors; ability to attract new customers and retain existing customers in the manner anticipated; reliance on and integration of information technology systems; changes in legislation or governmental regulations affecting the companies; international, national or local economic, social or political conditions that could adversely affect the companies or their customers; conditions in the credit markets; risks associated with assumptions the parties make in connection with the parties’ critical accounting estimates and legal proceedings; the continuing recovery in the mining industry; prevailing prices for various commodities; the timing and extent of future oil and gas drilling and production in the Delaware Basin; longer term weather patterns; the availability of credit; the availability of equity or debt capital needed for the business and foreign currency fluctuations that may affect Layne’s and Granite’s results of operations. Additional factors that may cause results to differ materially from those described in the forward-looking statements are set forth in the reports filed with the Securities and Exchange Commission (the “SEC”) and in each company’s other filings made with the SEC available at the SEC’s website at www.sec.gov.
