UPDATE: EnergySolutions Amends Energy Capital Partners Merger Pact

EnergySolutions, Inc.

, a leader in nuclear commercial services, today announced that it has signed an amendment to its definitive acquisition agreement with a subsidiary of Energy Capital Partners II, LLC ("Energy Capital" or "ECP"). Under the terms of the amended agreement, EnergySolutions' shareholders will now receive $4.15 in cash for each share of common stock. Carlson Capital, L.P., the largest beneficial institutional owner of the Company's stock, who had previously voiced opposition to the acquisition, has informed the Company that they intend to vote in favor of the transaction based on the amended terms. "We are extremely pleased to have reached this amended agreement with Energy Capital," stated David Lockwood, CEO and President of EnergySolutions. "We strongly believe that this offer provides compelling value for our shareholders and will enables us to continue to execute on our strategic plan by providing the investment capital to de-lever our balance sheet and grow our business. We have been able to visit with many of our larger shareholders and value their support of this transaction." "We have increased the purchase price principally to gain broader support of shareholders for this transaction," said Tyler Reeder, a Partner at ECP. "The increased offer reflects our dedication to EnergySolutions and the important work that they do." ECP also stated that the enhanced merger consideration constitutes a "best and final" offer. The ECP acquisition of EnergySolutions is subject to remaining closing conditions, including regulatory approvals by the Nuclear Regulatory Commission and the State of Utah as well as approval by EnergySolutions' stockholders at the special stockholders meeting on April 26, 2013.
