QUIDEL ANNOUNCES STRONG FOURTH QUARTER RESULTS
Reports Earnings from Continuing Operations of $0.28 Per Share
SAN DIEGO (February 15, 2006) – Quidel Corporation (NASDAQ: QDEL), a leader in point-of-care rapid diagnostic tests, today announced unaudited financial results for its fourth quarter and year ended December 31, 2005.
Fourth Quarter Financial Results
For the fourth quarter of 2005, total revenues rose 9% to $34.8 million, compared with total revenues of $31.9 million for the fourth quarter of 2004. Worldwide product sales growth of 8% for the fourth quarter of 2005 was led by Strep A with a 17% increase, pregnancy with an 11% increase and influenza with a 10% increase over prior year. International product sales increased 16% compared with the fourth quarter of 2004, due to increased demand for the Company’s influenza tests and bone health products.
Gross margin for the 2005 fourth quarter increased to 62% from 59% in the fourth quarter of 2004, primarily due to higher product sales, a more favorable geographic and product mix and a price increase on the majority of the Company’s products. Operating expenses for the fourth quarter of 2005 were $11.9 million, compared with $10.7 million for the fourth quarter of 2004. The increase in operating expenses relates primarily to planned increases in research and development, clinical trials, and sales and marketing expenses associated with the Company’s QVB™ (Quidel Value Build) programs.
For the fourth quarter of 2005, earnings from continuing operations were $9.8 million, or $0.28 per diluted share, compared with earnings from continuing operations of $6.0
million, or $0.19 per diluted share, for the fourth quarter of 2004. Loss on discontinued operations, net of tax, for the fourth quarter of 2005 was $0.2 million, or $0.00 per share, compared with a loss of $6.7 million, or $0.21 per share, for the fourth quarter of 2004. Net earnings for the fourth quarter of 2005 were $9.6 million, or $0.28 per diluted share, compared with a net loss of $0.6 million, or $0.02 per diluted share, for the fourth quarter of 2004.
Liquidity
Cash and cash equivalents as of December 31, 2005 were $34.9 million, compared with $36.3 million as of December 31, 2004. The year-over-year decrease in cash includes the one-time $17 million payment made as part of the previously-disclosed patent litigation settlement in April 2005.
2005 Full Year Financial Results
Total revenues for the year ended December 31, 2005 were $92.3 million, up 17% compared with total revenues of $78.7 million in 2004. Strong sales growth in all core product lines included full-year sales of influenza tests up 32%, pregnancy tests up 19%, and Strep A tests up 19%. Significant percentage growth was also recorded in mononucleosis and bone health products compared with 2004.
Gross margin for 2005 was 58%, compared with 54% in 2004, primarily reflecting higher product sales, a more favorable geographic and product mix, and a price increase on the majority of the Company’s products. Excluding the $17 million expense paid under the terms of the patent litigation settlement in the first quarter of 2005, operating expenses for 2005 were $43.5 million, compared with $41.6 million for 2004, primarily as a result of higher research and development costs associated with work on new technologies and increased market research, clinical trials, promotion and advertising costs for key products and development of brand value which were partially offset by lower legal fees for 2005 due to the previously-disclosed patent litigation settlement. The net loss for 2005 was $9.3 million, or $0.28 per diluted share, compared with a net loss for 2004 of $6.3 million, or $0.20 per diluted share, in 2004.
2005 Non-GAAP Results
For the year ended December 31, 2005, adjusted net earnings were $11.7 million, or $0.35 per diluted share. This compares with adjusted net earnings of $1.6 million, or
$0.05 per diluted share, for the year ended December 31, 2004. The components of adjusted net earnings are identified and discussed below under “Non-GAAP Financial Information.”
“We are very pleased with our strong finish to a very strong year for our Company. We delivered substantially improved revenue and earnings from continuing operations, exclusive of litigation settlement, for the fourth quarter and full year 2005 and continued to capitalize on the investments and meet the imperatives outlined for market leadership in rapid diagnostic tests at the point of care in infectious disease and reproductive health. We will continue to invest in manufacturing, research and development and marketing, all of which establish the foundation for further growth and market leadership. In 2006, we expect continued growth from our core product lines and anticipate a strong market entry for our iFOBT test, launched in January of 2006, which aids in the detection of colon cancer. In addition, we anticipate the launch of our new test for respiratory syncytial virus (RSV) to be available for the 2006/2007 cold and flu season” said Caren Mason, President and CEO.
Non-GAAP Financial Information
The Company is providing non-GAAP financial information to reflect the effect of certain non-recurring items on earnings and net earnings per share as a supplement to its consolidated financial statements, which are presented in accordance with generally accepted accounting principles in the U.S., or GAAP. Included in the items in the GAAP net loss but excluded from the adjusted net earnings are: the $17 million payment in 2005 made as part of the patent litigation settlement, a resulting increase in the Company’s tax provision due to the impact of the settlement on the Company’s assessment of deferred tax assets, and discontinued operations encompassing the Company’s urinalysis and ultrasonometer businesses.
Management is providing the adjusted net earnings and adjusted net earnings per share information for the periods presented because it believes this enables a better comparison of the Company’s financial performance from period-to-period, and to that of its competitors. This presentation is not meant to be considered in isolation, or as a substitute for results prepared in accordance with GAAP. A reconciliation of the non-GAAP financial measures to the comparable GAAP measures is included in this release as part of the attached financial tables.
Conference Call Information
Quidel management will host a conference call to discuss these topics today beginning at 5:00 p.m. Eastern time (2:00 p.m. Pacific time). To participate via telephone, please call (888) 803-7396 from the U.S. or (706) 634-1052 for international callers.
