Aegion Enters into Amended Merger Agreement with Affiliates of New Mountain Capital to Increase Consideration to $30.00 Per Share in Cash

All-Cash Transaction Valued at Approximately $1.1 Billion

Aegion Board of Directors Recommends Voting “FOR” Approval of Amended Merger Agreement at Upcoming May 14 Stockholder Meeting

ST. LOUIS, April 14, 2021 (GLOBE NEWSWIRE) -- Aegion Corporation (NASDAQ: AEGN) today announced that it has entered into a second amendment to the definitive merger agreement with affiliates of New Mountain Capital, L.L.C. (“New Mountain”, and together with such affiliates “Buyer”), a leading growth-oriented investment firm headquartered in New York, to increase the consideration payable to holders of outstanding shares of Aegion common stock to $30.00 per share in cash from $27.00 per share in cash.

The revised transaction price represents a total enterprise value of $1.1 billion, including net debt. The revised per-share price represents a premium of 40% and 48% to Aegion’s closing share price and 30-day VWAP, respectively, as of February 12, 2021, the last trading day prior to announcing the definitive merger agreement with New Mountain.

Pursuant to the amendment, as consideration for the increased purchase price, the break-up fee payable by Aegion in certain circumstances has increased from $40 million to $50 million. The termination fee payable by Buyer to Aegion in certain circumstances has also increased from $70 million to $90 million.

In evaluating this amendment, in consultation with its outside legal and financial advisors, Aegion’s Board of Directors gave due consideration to a revised proposal received from an unsolicited third party (the “Third Party”) (the “Third-Party Proposal”) to acquire 100% of the shares of Aegion for $30.00 per share in cash. The Third-Party Proposal followed discussions and negotiations between the Third Party and management in the last few weeks following the disclosure on March 22, 2021 of the Board’s determination that an unsolicited proposal from the Third Party for $28.50 per share in cash could reasonably be expected to result in a “Superior Proposal.” In making its decision, the Board carefully assessed the relative benefits and risks of the revised proposals from both New Mountain and the Third Party. The Board determined that, based on the consideration payable to stockholders and the superior certainty and anticipated timing to close the transaction with New Mountain, Aegion’s entry into the amendment with New Mountain is in the best interests of Aegion’s stockholders.
