L. Heath Sampson, President and CEO of ADES commented, “We are very pleased to announce this stock repurchase program, which is supported by our solid balance sheet and strong cash generating business model. This tender offer, when coupled with our previously announced recurring quarterly dividend program, which we expect will commence late in the second quarter, could result in the return of up to $32 million to shareholders over the next few quarters. We will continue to take a balanced approach to capital allocation moving forward, as we balance future dividend and share repurchase programs, against investment in our growing chemicals business and potential accretive merger and acquisition opportunities.”

The modified Dutch Auction will allow all the Company's stockholders to tender some or all of their shares at a price within a specified range and to do so without incurring any brokerage fees or commissions. Based on the number of shares tendered and the prices specified by the tendering stockholders, the Company will select a single price per share within the range that will enable the Company to purchase 925,000 shares pursuant to the offer, or such lesser amount of its shares that are properly tendered. All shares accepted in the tender offer will be purchased at the same price per share even if a stockholder tendered at a lower price. The Company reserves the right in the tender offer to purchase up to an additional 2% of its shares outstanding. As of May 1, 2017, the Company had 22,294,573 shares outstanding.

The Company’s directors and executive officers do not intend to participate in the offer and do not intend to tender any of their shares, except that the Company has been advised that Alta Fundamental Advisers LLC (“Alta Fundamental”), which currently owns approximately 4.90% of the Company’s outstanding common stock, intends to sell shares in the tender offer so that upon conclusion of the tender offer, Alta Fundamental will continue to own less than 5.0% of the Company’s outstanding common, Mr. Gilbert Li, a director of the Company, may be deemed to beneficially own such Alta Fundamental shares because he is a manager of Alta Fundamental and holds dispositive powers over such shares.
