EXTON, Pa., Feb. 24 /PRNewswire-FirstCall/ -- ViroPharma Incorporated reported today its financial results for the fourth quarter and year ended December 31, 2008.

Key events since September 30, 2008 include:

Operational:

Development:

Financial Results:

"While, clearly the early part of 2009 produced disappointing clinical results for maribavir, 2008 was a very successful year for ViroPharma -- from strong financial results to great execution in all aspects of our business to the transformational acquisition of Lev Pharmaceuticals and the launch of Cinryze. As a result we believe we have positioned ourselves with a number of growth drivers and multiple opportunities for success," stated Vincent Milano, ViroPharma's president and chief executive officer. "Those who follow our company can look for a number of exciting milestones throughout the upcoming year, such as progress on Cinryze, including the ongoing commercial launch and our acute indication sBLA with a June PDUFA date; continued success with Vancocin; the planned initiation of clinical studies for NTCD; and continued strong financial performance."

Net sales of Vancocin were $50.0 million for the fourth quarter of 2008 and $232.3 million for the year ended December 31, 2008, as compared to $47.7 million and $203.8 million in the respective 2007 periods.

Operating income for the year ended December 31, 2008 was $78.7 million. Our operating loss for the fourth quarter 2008 was $3.4 million. These amounts are compared to operating income of $115.8 million and $19.0 million for the year and fourth quarter of 2007, respectively. Operating income decreased in both comparative periods primarily due to increased amortization expense, the growth in the investment in our pipeline and increased SG&A costs.

Net loss in the fourth quarter ended December 31, 2008 was $1.0 million, compared to net income of $20.4 million for the same period in 2007. For the twelve months ended December 31, 2008, net income was $67.6 million, compared to $95.4 million for the same period in 2007. Net loss per share for the quarter ended December 31, 2008 was $0.01 per share, basic and diluted, compared to a net income of $0.29 per share, basic, and $0.25 per share, diluted, for the same period in 2007. Net income per share for the year ended December 31, 2008 was $0.95 per share, basic, and $0.83 per share, diluted, compared to net income of $1.37 per share, basic, and $1.21 per share, diluted, for the same period in 2007.

The primary drivers of the decrease in net income for the fourth quarter and year ended December 31, 2008 were the increase in R&D, SG&A and intangible amortization expenses, and lower interest income offset by the lower tax expense. Additionally, in the fourth quarter of 2008 we had a $2.3 million charge to write down to fair value our previous corporate headquarters which is currently held for sale.

Operating Highlights

During the three months and year ended December 31, 2008, net sales increased 4.9 percent and 14.0 percent, respectively, compared to the same periods in 2007.

The cost of sales for the three months and year ended December 31, 2008 increased $0.1 million and remained consistent, respectively, as compared to the same periods in 2007. For the three months and year ended December 31, 2008 the cost of sales was $2.1 million and $8.9 million, respectively, compared to $2.0 million and $8.9, respectively, for the same period in 2007.

Investment in our product pipeline and the company continued to grow as research and development (R&D) and selling, general and administrative (SG&A) expenses in the fourth quarter and year ended December 31, 2008 were $43.6 million and $131.7 million, respectively compared to $25.2 million and $72.9 million for the fourth quarter and year ended December 31, 2007, respectively. The quarter increases were due primarily to our investments in our infrastructure related to our development programs, costs to support the Cinryze open label trial and launch related costs, and increased personal and personal related costs for our technical operations. For the year ended December 31, 2008, increased expenses resulted from investments in our development programs, increased medical education activities and increased marketing activities.

Our effective income tax rate was a benefit of 76.3 percent and an expense of 18.0 percent for the quarters ended December 31, 2008 and 2007, respectively and an expense of 22.4 percent and 29.7 percent for the year ended December 31, 2008 and 2007, respectively. Our income tax expense includes federal, state and foreign income taxes at statutory rates and the effects of various permanent differences. The decrease in the 2008 rate as compared to 2007 is primarily due to the impact of the orphan drug credit for maribavir and the decreased level of income before taxes.

Working Capital Highlights

As of December 31, 2008, ViroPharma's working capital was approximately $305.4 million, which represents a $289.0 million decrease from December 31, 2007, caused by a $366.4 million decrease in the fourth quarter of 2008 mainly related to the acquisition of Lev ($380.2 million), offset slightly by operating cash flows. Cash flow from operating activities for the three months and year ended December 31, 2008 was $0.6 million and $91.4 million, respectively.

Business Development Highlights

In October 2008, we completed our acquisition of Lev. Lev was a biopharmaceutical company focused on developing and commercializing therapeutic products for the treatment of inflammatory diseases. The terms of the merger agreement provided for the conversion of each share of Lev common stock into upfront consideration in the aggregate amount of $442.9 million, or $2.75 per Lev share, comprised of $2.25 per share in cash and $0.50 per share in ViroPharma common stock, and contingent consideration (CVRs) of up to $1.00 per share which may be paid upon the achievement of certain regulatory and commercial milestones. The first CVR payment of $0.50 per share (or $87.5 million) would become payable when either (i) Cinryze is approved by the FDA for acute treatment of HAE and the FDA grants orphan exclusivity for Cinryze encompassing the acute treatment of HAE to the exclusion of all other human C1 inhibitor products or, (ii) orphan exclusivity for the acute treatment of HAE has not become effective for any third party's human C1 inhibitor product by October 21, 2010. The second CVR payment of $0.50 per share ($87.5 million) would become payable when Cinryze reaches at least $600 million in cumulative net product sales within 10 years of closing of the acquisition.

Disclosure Notice

Certain statements in this press release contain forward-looking statements that involve a number of risks and uncertainties. Forward-looking statements provide our current expectations or forecasts of future events. Forward looking statements in this press release include our financial guidance for 2009, and statements regarding our clinical development programs, the effectiveness of our Vancocin and Cinryze sales efforts, our estimates of future tax rates, or our ability to execute a successful launch of Cinryze, our ability to conduct future studies with maribavir, and the timing and potential outcomes of the review of our regulatory submission related to an acute treatment indication for Cinryze.

Our 2009 revenue guidance is based upon our plans to remain vigorous in our opposition to any bioequivalence approach considered for use in approving generic formulations of Vancocin that does not require rigorous scientific methods to demonstrate safety and efficacy consistent with good medicine and science. There can be no assurance that the FDA will agree with the positions stated in our Vancocin related submissions or that our efforts to oppose the FDA's December 2008 bioequivalence guidance for Vancocin will be successful. We cannot predict the timeframe in which the FDA will make a decision regarding either our citizen petition for Vancocin or the approval of generic versions of Vancocin. If we are unable to change the recommendation set forth by the FDA in December 2008, the threat of generic competition will be high. The entry of competing generic products will significantly affect our sales of Vancocin and our financial performance.

Our actual results may vary depending on a variety of factors, including:

There can be no assurance that we will conduct additional CMV studies in the future. The FDA or other regulatory authorities may prohibit any future studies with maribavir or alternatively may require additional or unanticipated studies or clinical trial outcomes before granting regulatory approval. There can be no guarantee that we will be successful in gaining regulatory approval of maribavir for any indications. The data that were submitted to the U.S. Food and Drug Administration includes data from two separate studies including the pivotal Phase 3 study of Cinryze in acute HAE attacks and the ongoing open-label study of Cinryze for acute treatment of HAE, which includes partial data from an ongoing open label study. The FDA may view the data regarding the use of Cinryze for acute treatment of HAE we have submitted as a supplemental BLA as insufficient or inconclusive, not accept our submission, request additional data, require additional clinical studies, delay any decision past the time frames anticipated by us, limit any approved indications, deny the approval of Cinryze for acute treatment of HAE or approve a competing product which has been granted orphan drug designation thereby preventing Cinryze from reaching the market for acute treatment of HAE. There can be no assurance that the FDA or EMEA will not require additional or unanticipated studies or clinical trial outcomes before granting regulatory approval of any of our product candidates, or that we will be successful in gaining regulatory approval of any of our product candidates. Currently our market capitalization is less than our book value. As a result, we may be required to take a significant non-cash goodwill impairment charge and may be required to write off goodwill or other intangible assets in the future. If we are required to write off goodwill or other intangible assets, our financial position or results of operations could be adversely affected. These factors, and other factors, including, but not limited to those described in ViroPharma's annual report on Form 10-K and quarterly reports on Form 10-Q filed with the Securities and Exchange Commission during 2008, could cause future results to differ materially from the expectations expressed in this press release. The forward-looking statements contained in this press release may become outdated over time. ViroPharma does not assume any responsibility for updating any forward-looking statements.
