Contura + Alpha Transaction: Financial FAQs  

Could you provide a high-level investment case for the combined company?

The transaction between Contura and Alpha is expected to create a stronger, more globally competitive coal company that will be the largest metallurgical coal supplier in the United States. With a strengthened balance sheet and improved competitive positioning, the post-merger company is expected to enjoy greater flexibility in blending and sales capabilities as well as diversification in its thermal platform. Additionally, the combined company is expected to realize annual synergies between $30 million and $50 million.

Can you provide more details on synergies expected to result from the transaction? What are the main categories of expected synergies?

The annual synergy target associated with the transaction is expected to be between $30 million and $50 million. The four main categories of targeted synergies are sourcing improvements, SG&A rationalization, coal blending and marketing optimization, and operational optimization.

How were the ownership percentages of the post-merger company determined (53.5% Contura and 46.5% Alpha)?

Following negotiation between the companies, percentage ownership of the post-merger company was approved by the boards of directors of both entities.

When will Contura’s shares begin trading on the NYSE and under what symbol?

As part of this transaction, Contura will take steps to become a public company and list shares of the post-merger company on the NYSE. The timing of the listing is expected to occur concurrently with the closing of the transaction.

Once determined, the combined company’s trading symbol will be announced as a part of the listing process.

Do you have any plans to conduct an additional offering of common stock to increase trading liquidity?

There are no current plans to conduct an additional offering. In the coming weeks, we will be focused on completing both the transaction and the process to list our shares on the NYSE. Any future decision to conduct an additional offering will be at the discretion of the board of the combined company.

What do you expect to be the combined company’s capital allocation priorities for 2018 and beyond?

As always, the company’s primary financial focus will be to maintain a healthy balance sheet. Beyond that, we will continue to evaluate where the best expected return on investment will be, whether that be organic growth, strategic acquisitions, or returning capital to shareholders, and allocate capital accordingly.

Do you plan to pursue any additional transactions in the next 12 to 18 months?

While we will always consider strategic opportunities, we plan to be fully focused on integration over the next few quarters and do not currently envision any additional transactions in the near-term.

As a result of Alpha’s October 2017 sale of inactive and idle assets to Lexington Coal Company (LCC), Alpha is scheduled to make $94 million in additional payments to LCC. Are they equal payments from 2018 to 2023? What is the timing of those payments?

No, the scheduled payments are not in equal amounts each year. The following are Alpha’s scheduled payments to Lexington Coal Company:

Do you expect any benefits with regards to surety and bonding? Can you quantify them?

Yes, we expect meaningful benefits in the surety and bonding area. While it is too early to quantify the exact amount expected from those benefits, we anticipate having approximately $100 million released from restricted cash over the next several quarters after the transaction closes, a portion of which is related to surety and bonding. As is customary with transactions of this nature, we expect the integration process to take several quarters before the full projected benefit will be achieved.

Will you conduct regular earnings calls going forward? Do you plan to attend investor conferences and conduct NDRs?

Yes, we plan to begin hosting regular earnings conference calls, as well as attending investor conferences, after the transaction is completed and the combined company’s shares begin trading on the NYSE. As announced, the transaction is currently expected to close in the third quarter of 2018.
