Cyalume Technologies Holdings, Inc. to Be Acquired by an Affiliate of Arsenal Capital Partners

Fort Lauderdale, FL - Cyalume Technologies Holdings, Inc. (OTCQB: CYLU) (the “Company” or “Cyalume”) today announced the signing of a definitive agreement and plan of merger, pursuant to which Cyalume will be acquired by an affiliate of Arsenal Capital Partners (“Arsenal”) in an all-cash transaction. The total cash consideration to be paid by the purchaser in the transaction is $45 million, subject to certain adjustments set forth in the merger agreement, which includes the repayment of outstanding indebtedness of the Company. The deal is expected to close in September 2017, subject to the satisfaction of the closing conditions set forth in the merger agreement. Upon completion of the transaction, the management team will remain in place.

Zivi Nedivi, Cyalume President and CEO, commented “We are very pleased to announce this transaction with Arsenal, as we believe it affords us the opportunity to both deliver a return to many of our various stake holders that have supported Cyalume over the past several years and positions the Company for continued growth and future success.” Dale S. Baker, Chief Operating Officer, added “We are very excited to have Arsenal as our partner and we are confident that with their strategic and financial support we will be able to significantly accelerate our growth in the specialty chemical, pharmaceutical and medical product markets.”

Sal Gagliardo, Industry and Operations Partner at Arsenal, said “Cyalume has a strong brand and long-term relationships with blue chip customers. Given its robust portfolio of technologies, we expect that Cyalume will serve as a platform for further acquisitions in the specialty chemicals and performance polymers sector. We look forward to partnering with the Cyalume team to expand the Company’s capabilities.” Roy Seroussi, Principal at Arsenal, added “The investment in Cyalume represents an opportunity for Arsenal to leverage its industry knowledge and operating expertise in the formulated materials sector to support the Company’s strategy.”

Terms of the Agreement

Under the terms of the merger agreement, each outstanding share of Cyalume common stock and preferred stock will be converted into the right to receive an amount in cash calculated in accordance with the terms of the merger agreement, other than any shares held by stockholders who are entitled to and who properly demand appraisal rights, in each case subject to the terms and conditions of the merger agreement. Cyalume currently estimates that, if the closing of the transaction were to occur on August 31, 2017, the total amount to be paid to holders of Cyalume’s common stock would be approximately $5.8 million, or approximately $0.2081 per share of common stock. However, because this amount is based on Cyalume’s current estimates of deductions from the purchase price, including its outstanding closing indebtedness, transaction expenses, closing working capital and other amounts described in the merger agreement, and because Cyalume does not know the actual date on which the closing will occur or actual amounts of the corresponding deductions, the actual portion of the purchase price payable to holders of common stock could be different.

Stockholders affiliated with certain directors of the Company who hold the requisite percentage of Cyalume shares of voting stock to approve the transaction have executed a written consent approving the transaction, thereby providing the required stockholder approval for this transaction. As a result, no further action by other stockholders of Cyalume is required to approve the transaction, but consummation of the transaction remains subject to certain closing conditions as set forth in the merger agreement. The merger agreement was unanimously recommended by a special committee of Cyalume’s Board of Directors and was then approved by Cyalume’s full Board.
