Quidel Announces Modification of Revenue Reporting

SAN DIEGO, CA --(Marketwired - January 23, 2017) - Quidel Corporation ( NASDAQ : QDEL ), a provider of rapid diagnostic testing solutions, cellular-based virology assays and molecular diagnostic systems, announced today that it will modify its presentation of the components of its major revenue categories.

During the fourth quarter of 2016, Quidel (the "company") modified its presentation of revenue to reflect how management strategically thinks about the business categories. In association with the change, the revenues of QuickVue® and Sofia® businesses will be reported within the company's Immunoassay category, and the revenues of Solana®, AmpliVue® and Lyra® products will be reported in the company's Molecular category. Quidel's Thyretain® and Diagnostic Hybrids, or DHI, revenues will be reported in the company's Virology category, and the Specialty Products Group, or SPG, businesses will be reported in the company's Specialty Products category.

"Our traditional reporting categories, such as Infectious Disease and Women's Health, for example, were historically useful, but this new approach we believe more accurately reflects how we think about the strategic components of the broader business, especially key pieces of the business, like our Immunoassay or Molecular product categories," said Douglas Bryant, president and chief executive officer of Quidel Corporation.

The following tables provide a recast of the components of quarterly revenue for the periods ended March 31, 2014 through September 30, 2016 and for the fiscal years ended December 31, 2014 and 2015. This information will be presented in future filings on the Company's Quarterly Reports on Form 10-Q and Annual Report on Form 10-K for applicable comparable periods.
