GISI and Hill International announce enhancements to their strategic merger agreement

August 27, 2022
  • All-cash transaction of approximately US$207 million, or $3.40 per share, plus assumed debt, represents a significant premium to Hill’s 90-day weighted average stock price
  • Amendment provides for a price increase from US$2.85 to $3.40 per share, a 19.3% increase from the previous price

LOS ANGELES and PHILADELPHIA, Aug. 27, 2022 (GLOBE NEWSWIRE) — Global Infrastructure Solutions Inc. (GISI) and Hill International, Inc. (NYSE:HIL) today announced that their boards of directors have approved enhancements to their definitive agreement of August 16, 2022, wherein they agreed to merge the diversified construction management companies, setting the stage for increased competitiveness and accelerated organic growth in global, for-fee infrastructure consulting markets. Following the receipt of an unsolicited proposal from a third party, Hill and GISI negotiated an amended and restated Merger Agreement under the terms of which the per share price is US$3.40, the transaction remains all-cash, and there is no financing contingency. Further, the transaction structure has been changed to a merger requiring the approval of Hill’s stockholders (rather than a tender offer to Hill stockholders). The transaction is expected to close in the fourth quarter of 2022, pending stockholder approval and regulatory review. The parties have also agreed to work together, if requested to do so by Hill, in order to provide Hill interim capital to allow Hill to take advantage of ongoing organic growth opportunities prior to closing.
