DexCom Inc. Reports Third Quarter 2009 Financial Results

Product revenue grew to approximately $4.6 million for the third quarter of 2009, an increase of 146% from the $1.9 million in product revenue reported for the third quarter of 2008, and an increase of approximately 12% from the $4.1 million reported for the second quarter of 2009. Total third quarter 2009 revenue, which includes development grant revenue, was $7.3 million, an increase of approximately 278% from the same quarter in 2008, and approximately 8% from the second quarter of 2009. The Company reported a net loss of $13.5 million, down from $15.6 million for the third quarter of 2008. Net loss was $0.29 per share for the third quarter of 2009, down from a net loss of $0.53 per share for the third quarter of 2008. The net loss included $4.2 million in non-cash expenses during the third quarter of 2009, centered primarily in share-based compensation and expense of the convertible debt discount.

Product cost of sales increased $1.0 million to $4.6 million for the third quarter of 2009 compared to $3.6 million for the same quarter in 2008, primarily due to increased product sales. Total cost of sales was $6.4 million for the third quarter of 2009, compared to $3.8 million for the third quarter of 2008. The increase was due to additional product sales and development costs related to development and collaboration agreements entered into during 2008. Research and development expense decreased by approximately $1.9 million to $3.5 million for the third quarter of 2009, compared to $5.4 million for the third quarter of 2008. The decrease in research and development expense was due primarily to the allocation of expenses to development cost of sales for activities performed pursuant to development and collaboration agreements entered into in 2008. Selling, general and administrative expense increased by approximately $2.3 million to $8.9 million for the third quarter of 2009, compared to $6.7 million for the third quarter of 2008, with the change primarily due to additional marketing, customer service, insurance reimbursement and sales costs. As of September 30, 2009, the Company had $40.4 million in cash, marketable securities, and restricted cash.
