DexCom Inc. Reports First Quarter 2007 Financial Results

SAN DIEGO - (BUSINESS WIRE-May 9, 2007) - DexCom, Inc. (Nasdaq:DXCM) today reported a net loss of $10.9 million or $0.39 per share for the first quarter of 2007, compared to $10.9 million or $0.43 per share for the first quarter of 2006.  The company reported revenues of $1.0 million for the first quarter of 2007 compared to $15,000 for the first quarter of 2006 following the launch of its first product on March 28, 2006.

“We continued to make progress developing the market for our STS system during the quarter and added over 900 new customers, while increasing revenues 21% compared sequentially to the fourth quarter of 2006,” said Steve Kemper, Chief Financial Officer. “We also continued to grow in a cash efficient manner, using only $8.4 million in cash from operations during the quarter.”

Cost of sales increased to $3.1 million for the first quarter of 2007 compared to $2.1 million for the first quarter in 2006. The increase was related to increased sales and higher factory overhead costs. Research and development expense decreased $1.5 million to $4.0 million for the first quarter of 2007, compared to $5.5 million for the first quarter of 2006.  Changes in research and development expense include reduced clinical, regulatory, and tooling costs.  Selling, general and administrative expense increased $1.5 million to $5.4 million for the first quarter of 2007, compared to $3.8 million for the first quarter of 2006.  The increase was primarily due to higher sales and marketing costs as the company continued to launch its STS system in the United States.

Cautionary Statement Regarding Forward Looking Statements

DexCom has a limited operating history. The company received approval from the FDA for its STS continuous glucose monitor on March 24, 2006, and has only recently launched the sale of this product throughout the United States. Successful commercialization and sale of the company’s products is subject to numerous risks and uncertainties, including product performance, a lack of acceptance in the marketplace by physicians and patients, the company’s inability to manufacture products in commercial quantities at an acceptable cost and quality level, possible delays in the company’s development programs, the inability of patients to receive reimbursements from third-party payors and inadequate financial and other resources. Certain of these risks and uncertainties, in addition to other risks, are more fully described in the company’s quarterly report on Form 10-Q for the period ending March 31, 2007, as filed with the Securities and Exchange Commission on May 9, 2007.
