IRVINE, Calif. and BURLINGTON, Mass., Aug. 16, 2023 (GLOBE NEWSWIRE) -- Keystone Dental Holdings, Inc. ("Keystone Dental") and Check-Cap Ltd. ("Check-Cap" or the “Company”) (NASDAQ: CHEK) today announced that they have entered into a definitive Business Combination Agreement (the "Business Combination Agreement") under which the stockholders of Keystone Dental will become the majority holders of the combined company. If completed, the business combination will create a public company headquartered in Irvine, CA and focused on advancing commercial execution and market development of Keystone Dental’s comprehensive portfolio of implants, arches and other tooth replacement solutions comprised of restoration products, prosthetic solutions, biomaterial, and digital dentistry capabilities.

Upon closing of the transaction, the combined company will trade on the NASDAQ under the symbol “KSD.” The executive team of Keystone Dental will serve as the executive team of the combined company, led by Melker Nilsson, Keystone’s Chief Executive Officer.

"We are excited to enter into a definitive business combination agreement with Keystone Dental, a commercial-stage medical technology company focused on providing end-to-end solutions for dental practitioners and tooth replacement procedures,” said Steven Hanley, Chairman of the Board of Directors of Check-Cap. “Following a comprehensive and thorough review of strategic alternatives that Check-Cap’s board and its advisors undertook involving the review of over 40 formal offers, Check-Cap’s Board of Directors concluded that the proposed transaction with Keystone Dental is in the best interest of our shareholders. We intend to hold a special meeting of Check-Cap shareholders in the fourth quarter of 2023 to vote on this business combination."

“The proposed business combination with Check-Cap is expected to be a transformative step forward in the execution of our mission to establish Keystone Dental as a leading, pure-play global provider of tooth replacement solutions. Over the past few years, we have developed a comprehensive portfolio of end-to-end solutions for dental practitioners and tooth replacement procedures with the goal of giving patients a better and more comfortable experience while providing our customers with unique tools to enhance their daily workflow. During that time, we have also established a growing salesforce across the U.S. and distribution system, which has contributed to our robust revenue growth and improved market share position among the premium players,” stated Mr. Nilsson.

Based upon the number of shares to be issued in the business combination, current Check-Cap security holders are expected to own approximately 15% of the combined company representing an equity valuation of $39.7 million and Keystone Dental security holders are expected to own approximately 85% of the combined company representing an equity valuation of $225 million. The actual allocation will be subject to adjustment based on Check-Cap’s net cash balance at the time of closing. The Business Combination Agreement provides for a Check-Cap net cash target of $22.3 million at closing of the transaction which implies a $17.4 million premium to the Check-Cap net cash target.

The proposed transaction has been approved by the board of directors of both companies. The business combination is subject to the approval of Check-Cap shareholders at a special meeting of shareholders, which is expected to occur in the fourth quarter of 2023, along with the satisfaction or waiver of other customary conditions.

Ladenburg Thalmann & Co. Inc. is acting as financial advisor to Check-Cap for the transaction. BofA Securities is acting as capital markets advisor to Keystone Dental.
