Middleton, WI, October 26, 2004 – Bone Care International, Inc. (Nasdaq: BCII) today announced financial results for its first fiscal quarter ended September 30, 2004. The Company reported record quarterly sales for Hectorolâ (doxercalciferol) of $17.4 million, compared to $8.1 million for the first quarter of fiscal 2004, representing a 114 percent increase. The Company achieved its third consecutive quarter of profitability, reporting net income of $1.2 million, or $0.06 per diluted share. In the first quarter of fiscal 2004 the Company reported a net loss of $2.1 million, or $0.15 per share. The Company ended the first quarter of fiscal 2005 with a total of $113.2 million in cash and investments.

“The strong first quarter performance reflects the sound execution of our customer business plans,” said Paul L. Berns, President and Chief Executive Officer of Bone Care International. “In particular we continued to advance our Hectorolâ brand as evidenced by the revenue growth of 114 percent compared to the first quarter of fiscal 2004, and 18 percent quarter-over-quarter. We accomplished our fifth consecutive quarter of double-digit growth, driven primarily by our Hectorolâ Injection product. The profitability in the first quarter of fiscal 2005 of $1.2 million was achieved while we continued to expand our sales organization, invested in research and development activities and continued to scale-up our launch efforts for our newly approved Hectorolâ 0.5 mcg Capsules. I want to recognize and thank our employees for their commitment to building our Company to better serve patients.”

Gross margin on sales of Hectorolâ was 75 percent in the first quarter of fiscal 2005 compared with a gross margin of 70 percent for the same period in fiscal 2004. The improvement in margin in fiscal 2005 was primarily due to a reduction in manufacturing validation costs.

Research and development expenses were $2.3 million, an increase of $521,000, or 29 percent, from the first quarter of fiscal 2004. This increase resulted primarily from investments in the Company’s pre-clinical and clinical programs, investments in the lifecycle development of the Hectorolâ brand and an increase in the clinical research support staff.

Selling, general and administrative expenses were $9.9 million, an increase of $3.8 million, or 63 percent, from the first quarter of fiscal 2004. This increase was primarily due to the launch of Hectorolâ 0.5 mcg Capsules, including $1.5 million for increased promotional activities and $1.9 million for the expansion of the sales organization.

“The growth in our sales organization has allowed us to execute on new business initiatives in both the national dialysis and independent dialysis segments which are designed to provide greater future potential in our business,” said Mr. Berns. Additionally, the excellent results achieved by our organization have allowed us to increase our sales guidance for fiscal 2005. Originally we had planned for total annual product sales to range between $71 and $76 million. We are now planning for product sales to range between $75 and $79 million for fiscal 2005.”

Additional highlights during the first quarter of fiscal 2005 included the hiring of Chrys Kokino to lead the Company’s marketing efforts and the appointment of Michael A. Appelbaum to the Company’s Board of Directors. Also, in July, the Company entered into a collaborative agreement with Cardinal Health, Inc. for the launch and commercialization of Hectorolâ 0.5 mcg Capsules with nephrologists in pre-dialysis, Stages 3 and 4 chronic kidney disease.
