Commenting on corporate performance, Carl H. Guild, Jr., President and Chief Executive Officer of TCC, said, "During the Company's second quarter ended March 31, 2018, we did not achieve our desired financial performance for fiscal 2018. Several international opportunities have made significant progress but have not yet closed due to delays in the evaluation and procurement process. TCC's products go through rigorous field and laboratory testing, which ensures that all customer requirements are met prior to procurement. We expect that some customer evaluations will be completed during the next quarter, thereby allowing associated procurements to proceed."

"TCC is committed to returning to profitability over the remainder of fiscal 2018. We continue to closely monitor and reduce operating expenses as appropriate, while strategically investing in business development efforts, developing productive relationships and expanding our sales channel network."
