Management Commentary

"We are reporting strong financial results for the second quarter that feature top-line growth, gross margin expansion, and expense control, leading to a 43% reduction in our operating loss versus the prior year,"said Thomas M. Patton, President and Chief Executive Officer of CASMED."Total FORE-SIGHT sales increased 17%, our third consecutive quarter of year-over-year double-digit growth, led by a 20% increase in U.S. FORE-SIGHT sales. Worldwide disposable sensor sales increased 13% and included 16% growth in U.S. sensor sales.

"Given our continued strong performance in the second quarter, we are affirming our full-year 2018 expectations for year-over-year mid-teen percentage growth for total FORE-SIGHT sales, U.S. FORE-SIGHT sales, and U.S. disposable sensor sales. We are raising our expectation for international FORE-SIGHT sales to a low double-digit increase over 2017."
