Quidel Announces Preliminary Revenue for Fourth Quarter

SAN DIEGO, CA --(Marketwired - January 06, 2017) - Quidel Corporation ( NASDAQ : QDEL ), a provider of rapid diagnostic testing solutions, cellular-based virology assays and molecular diagnostic systems, announced today that it expects revenues in the fourth quarter of 2016 to be in the range of $52 to $53 million.

"According to the CDC, the proportion of outpatient visits for Influenza-like Illness (ILI) crossed the 2.2% national baseline in Week 50, indicating a later start to the Influenza season. In comparison, the 2014-2015 Influenza season crossed the national baseline in Week 47. These data correlate with the insights gleaned from our Virena® Influenza test data, which indicate that people are testing, but the number of positive Influenza diagnoses has not risen until fairly recently. Having said that, the CDC's ILI data for Week 51 measured 2.9%, and suggest to us that the Influenza season has begun," said Douglas Bryant, president and chief executive officer.

"We do continue to see end user demand for our Respiratory Disease products, as our Sofia instruments now total over 17,500 placements," added Bryant.

These preliminary results are based on management's initial analysis of operations for the quarter ended December 31, 2016. The company expects to issue full financial results for the fourth quarter and fiscal year 2016 in February.
