Auxilium Pharmaceuticals Announces First Quarter 2006 Financial Results

MALVERN, Pa., May 9 /PRNewswire-FirstCall/ -- Auxilium Pharmaceuticals, Inc. , a specialty pharmaceutical company, today announced financial results for the quarter ended March 31, 2006. For the first quarter of 2006, Auxilium reported net revenues of $14.9 million compared to net revenues of $8.8 million in the first quarter of 2005.

“Testim delivered another quarter of record performance with solid growth in sales, prescriptions and market share, marking the 12th consecutive quarter of all-time high net revenues for Auxilium,” said Ms. Gerri Henwood, Chief Executive Officer. “Testim continues to be an important source of support for the Company and the late-stage clinical development programs that we look forward to advancing into pivotal trials later this year.”

First Quarter 2006 Highlights: * According to National Prescription Audit data from IMS, a leading market research firm, Testim’s market share increased again and for the month of March 2006 represented 16.9% of total prescriptions for testosterone gels. This compares to 12.1% for the month of March 2005. * In January 2006, we began a Phase III long-term safety trial in the European Union for AA2600, our testosterone replacement transmucosal film product candidate. This trial, which is critical to achieving our timelines for the U.S. filing of AA2600, met patient enrollment targets during the first quarter. We expect to commence the U.S. Phase III pivotal trial for AA2600 in the second quarter of 2006. First Quarter Financial Detail

For the quarter ended March 31, 2006, Auxilium reported net revenues of $14.9 million compared to net revenues of $8.8 million in the first quarter of 2005. Net revenues for 2006 include a one-time benefit of $1.2 million, resulting from the adoption of the wholesaler method of revenue recognition under which revenue, net of estimated customer returns and allowances, is recognized at time of shipment to our customers. Prior to 2006, revenue was deferred until units were dispensed through patient prescriptions. Excluding this one-time increase, net revenues for the 2006 first quarter increased 56% over the comparable 2005 period.

For the quarter ended March 31, 2006, Auxilium reported a net loss of $(9.7) million, or $(0.33) per share, compared to a net loss of $(11.6) million, or $(0.56) per share, for the first quarter of 2005. The net loss for 2006 was reduced by a one-time benefit of $0.7 million, or $0.02 per share, resulting from the change to the wholesaler method of revenue recognition. As of January 1, 2006 the Company implemented Statement of Financial Accounting Standard No. 123R (SFAS 123R) which requires companies to estimate on grant date the fair value of share-based payment awards to employees and directors, and record compensation expense in their financial statements. The Company’s financial statements for periods prior to 2006 do not include any SFAS 123R costs related to employee or director stock options. As a result of adoption of SFAS 123R, the net loss for the first quarter of 2006 includes additional stock compensation expense of $0.3 million, or $0.01 per share.

Auxilium’s gross margin on net revenues was 74.1 % for the first quarter of 2006 and 67.9 % for the first quarter of 2005. Excluding the change in revenue recognition, gross margin was 75.5% for the first quarter of 2006. Gross margin reflects the cost of product sold as well as royalty payments made to the Company’s licensor on the sales of Testim. The improvement in gross margin reflects the benefit of year-over-year price increases, a reduction in the royalty rate paid to the Company’s licensor, and manufacturing cost reductions. First quarter 2006 gross margin includes amortization of up-front and milestone revenues received under an international marketing and distribution agreement which commenced in the third quarter of 2005. The gross margin rate for the first quarter of 2006 was positively impacted in comparison to 2005 by the lack of low-margin sales on international product shipments.

Research and development costs for the first quarter of 2006 were $8.4 million compared with $9.1 million for the comparable year-ago period. Research and development expenses for the first quarter of 2005 included the accrual of a $3.0 million anniversary payment under the AA4500 license and development agreement and a $0.5 million up-front payment for licensing the rights to various pain formulations using the transmucosal film technology. Excluding these items, the increase in research and development expense in the first quarter of 2006 compared to the first quarter of 2005 was primarily due to the increased spending for development and manufacturing scale up for AA4500 and ongoing investment in developing AA2600.

Selling, general and administrative expenses totaled $12.9 million for the quarter ended March 31, 2006 compared with $8.7 million for the year-ago quarter. The increase was primarily due to higher investment in promotional spending including the costs associated with Auxilium’s co-promotion agreement with Oscient Pharmaceuticals Corp., and the additional stock compensation expense resulting from the adoption of SFAS 123R.

At March 31, 2006, Auxilium had $44.1 million in cash, cash equivalents, and short-term investments compared to $56.7 million at December 31, 2005.
