AUSTIN, Texas, — Luminex Corporation (NASDAQ: LMNX) today announced a restructuring plan focused on its Assay and Related Products (“ARP”) Segment’s Newborn Screening Group and its Brisbane, Australia office. The Company anticipates it will reduce its workforce by approximately 5% and close its Brisbane, Australia office. This plan has been put in place to reduce expenses and better align the Company’s resources with its focused growth initiatives. As part of the restructuring, the Company will make additional investments in R&D and commercial operations to support the development of its next generation molecular diagnostics products and the sales and marketing of these products.

On an ongoing basis, we review our strategic priorities, market position and allocation of resources. These changes reflect an increased focus on our growth initiatives and our ongoing strong commitment to a leadership position in molecular diagnostics and our partnership franchises” said Patrick J. Balthrop, president and chief executive officer of Luminex. “While we never take decisions that affect the composition of our workforce lightly, we strongly believe that this reallocation of resources and related adjustments will make our company stronger and deliver value to our shareholders in the short term and the long term.”

Approximately half of the restructuring charge is expected to be expensed in the quarter ending September 30, 2013, with the remainder expected to be expensed in the quarters ending December 31, 2013 and March 31, 2014. The Company expects approximately $1.1 million of the total charge to be in the form of cash expenditures, the majority of which is expected to be paid out in the quarters ending September 30, 2013 and December 31, 2013.

The Company reaffirms its 2013 annual revenue guidance of between $220 and $230 million. As previously stated in our second quarter earnings call, we expect a challenging reimbursement environment near-term for select molecular diagnostic tests that could weigh on overall corporate performance and have cautioned investors toward the lower end of this revenue range.

Management will hold a conference call webcast to discuss the restructuring on August 8, 2013, at 8:30 a.m. Eastern Time.
