NxStage Medical Reports First Quarter 2007 Results

Tuesday May 8, 2007

LAWRENCE, Mass., May 8 /PRNewswire-FirstCall/ — NxStage Medical, Inc. (Nasdaq: NXTM), the manufacturer of the NxStage System One &#153 portable kidney dialysis machine, today announced its financial results for the first quarter ended March 31, 2007.

Revenues for the first quarter of 2007 were $8.4 million, compared to $3.4 million in the first quarter of 2006, an increase of 146%. Revenues in the chronic home dialysis market were $5.4 million for the first quarter of 2007, compared to $1.8 million in the first quarter of 2006. Revenues in the critical care market for the first quarter of 2007 were $2.9 million, compared to $1.6 million in the first quarter of 2006.

At the end of the first quarter of 2007, NxStage was working with 200 dialysis centers to provide home hemodialysis therapy with its System One to 1,295 end-stage renal disease (ESRD) patients. This compares to 174 centers and 1,022 patients at the end of 2006. NxStage also continued its successful roll-out of the PureFlow SL, a key element of its margin improvement strategy. At the end of the first quarter 2007, PureFlow penetration reached 47% of all System One machines in the chronic market.

I am very pleased with our strategic accomplishments in the first quarter, as we focused on long-term initiatives to drive NxStage’s growth and increase the Company’s gross margins, said Jeffrey H. Burbank, President & CEO of NxStage Medical. We formed three long-term distribution collaborations with our top dialysis center partners, signed two key, long- term supply agreements, and established plans to begin manufacturing in Mexico. We expect that these initiatives will raise awareness of home hemodialysis, increase patient access to the System One and reduce our product costs, while advancing NxStage’s mission of transforming renal care.

NxStage reported a net loss of $12.0 million, or ($0.41) per share, for the first quarter of 2007, compared with a net loss of $9.3 million, or ($0.44) per share, for the first quarter of 2006, reflecting increased sales and marketing and distribution expenses to support the Company’s commercialization efforts.

Cash, cash equivalents and short term investments as of March 31, 2007 were $70.7 million, compared to $61.8 million at the end of 2006. The balance at the end of the first quarter reflects the net proceeds of $20 million from the sale of 2,000,000 shares of common stock to DaVita Inc.

Recent Highlights

In the first quarter of 2007, NxStage announced multiple strategic initiatives designed to drive the growth of System One and increase the Company’s gross margins, including:

  • Long-term agreements with two of its key suppliers, Medisystems Corporation and Membrana GmbH, as part of a broad strategy to reduce product costs and secure supply to meet the growing demand for the System One;
  • A multi-year, national distribution agreement, with certain market rights, for the System One with DaVita under which the two companies will collaborate on expanding the availability of home hemodialysis to patients. DaVita made a $20 million investment in the Company’s stock, purchased its existing base of System One machines for $5 million and agreed to purchase, rather than rent, the majority of its equipment requirements going forward;
  • Multi-year distribution agreements for the System One with Wellbound and Renal Advantage, two other leading dialysis chains; and
  • Plans to initiate manufacturing of certain System One products in Mexico as part of its ongoing efforts to reduce product costs and optimize operations. Beginning this month, NxStage expects to execute a phased relocation of the manufacture of its PureFlow SL disposables and System One cycler to a new facility in Mexico provided by The Entrada Group.

Guidance

For the second quarter of 2007, NxStage expects revenue to be in the range of $9.7 million to $10.3 million. The Company expects a net loss in the range of ($12.4) million to ($12.8) million or ($0.41) to ($0.43) per share, including estimated non-cash stock-based stock compensation charges of $750,000 to $850,000. The Company expects to add approximately 300 to 340 additional net patients and 30 to 40 new centers offering therapy with the NxStage System One during the second quarter.

For the full year 2007, the Company expects revenue to be in the range of $42.0 million to $45.0 million and to end the year with 2,200 to 2,400 patients at approximately 330 centers offering therapy with the NxStage System One.
