Contura Internal Employee Announcement
From Kevin Crutchfield, Chief Executive Officer
(7.16.18)

Over the past weeks and months, we’ve been working diligently on the merger process with Alpha. As you might imagine, the vast majority of this work has been occurring behind the scenes, but I wanted to provide you with an update on the good progress we are making and share a few of those details with you.

On Friday, we submitted a preliminary registration statement on Form S-4 with the Securities and Exchange Commission (SEC). This is one of the important steps necessary in order for Contura stock to begin trading on the New York Stock Exchange (NYSE) once the merger with Alpha closes. Given the volume and breadth of information required for submission, there are still pieces of the S-4 filing that need to be updated as the process moves ahead. As the attached news release explains, our filing is therefore confidential for now, meaning the details of the statement will be made public at a later date once the additional information is submitted. This is a customary practice that allows us to work with the SEC to achieve the appropriate milestones in the registration process while Contura and Alpha continue gathering the remaining information required for the filing.

Additionally, we’ve been working with the U.S. Federal Trade Commission (FTC) to seek an early termination of the waiting period required under federal law to review potential anti-trust implications for transactions of this nature.  In early July, the FTC granted our request.  Basically, this means that the FTC found no reason to believe competition in our industry will be substantially reduced because of the merger.  The transaction is now expected to close prior to year-end.

Within the organization, we’ve made great strides in merger preparation as well. Department heads and functional leaders have been working together on a cross-functional transition team and with their Alpha counterparties to identify and execute on the steps necessary for a smooth integration once the merger is complete. This is important work, and I am pleased with the progress that has been made in such a short period of time.

As we continue moving toward the merger’s expected completion, I will share additional details as I can about other milestones in the process. In the meantime, it’s critical that we all remain committed to safe operations throughout the organization each and every day.

Keep doing good work, and continue to look out for each other.
Kevin
