CASMED Reports Preliminary Sales for Fourth Quarter and Full Year 2013

Places 90 FORE-SIGHT(R) Cerebral Oximeter Monitors During the Quarter

BRANFORD, Conn., Jan. 8, 2014 (GLOBE NEWSWIRE) -- CAS Medical Systems, Inc. (Nasdaq:CASM) (CASMED), a leader in medical devices for non-invasive patient monitoring, today reported preliminary top-line unaudited results for the fourth quarter and full year 2013.

The Company expects net sales for the fourth quarter of 2013 to be between $5.85 million and $5.95 million, compared with net sales of $5.95 million for the fourth quarter of 2012. FORE-SIGHT Oximetry product sales for the fourth quarter are expected to be between $2.5 million and $2.6 million with U.S. sensor sales growth accelerating to above 30% compared to the fourth quarter of 2012. For the full year 2013, net sales are expected to be between $21.8 million and $21.9 million, compared with net sales of $22.7 million for 2012. FORE-SIGHT sales for the full year are expected to be between $9.0 million and $9.1 million, compared to $7.8 million for 2012.

CASMED also disclosed that it shipped to customers a net 90 FORE-SIGHT cerebral oximeters in the fourth quarter. This compares with average net shipments of 35 monitors in each of the previous three quarters. Fourth quarter shipments were driven by demand for the company's next-generation FORE-SIGHT ELITE™ cerebral oximeter which was launched into the market in late September 2013. 

"Preliminary fourth quarter sales results reflect solid market acceptance of our new FORE-SIGHT ELITE monitor," said Thomas M. Patton, President and Chief Executive Officer of CASMED. "We believe the strong demand for the ELITE is allowing us to gain market share and should result in solid growth in disposable sensor sales during 2014."

CASMED expects to report financial results for the fourth quarter of 2013 and hold an investment-community conference call in early March 2014.
