SAN DIEGO, CA - (BUSINESS WIRE-March 9, 2010) - DexCom, Inc. (Nasdaq:DXCM) today reported its audited financial results as of and for the quarter and fiscal year ended December 31, 2009.

For the full-year ended December 31, 2009, product revenue grew to $18.0 million, an increase of 122% from the $8.1 million in product revenue reported for 2008, and total revenue grew to $29.7 million, an increase of 202% from 2008. Product revenue totaled $6.6 million for the fourth quarter of 2009, an increase of 169% from the $2.5 million in product revenue reported for the comparable period in 2008. Total fourth quarter 2009 revenue, which included development grant and other revenue, was $10.5 million, an increase of 157% from the comparable period in 2008. Product gross margin (deficit) totaled $1.2 million and $(0.2) million for the three and twelve months ended December 31, 2009, compared to $(1.1) million and $(5.3) million for the three and twelve months ended December 31, 2008. The Company reported a net loss of $11.5 million, or $0.25 per share, and $53.5 million, or $1.21 per share, for the three and twelve months ended December 31, 2009, down from $14.4 million, or $0.49 per share, and $58.9 million, or $2.00 per share, for the three and twelve months ended December 31, 2008. The net loss for 2009 included $16.4 million in non-cash expenses, comprised primarily of share-based compensation, accretion of non-cash interest expense related to our convertible notes, depreciation, and amortization.

Total cost of sales for the twelve months ended December 31, 2009 totaled $26.0 million compared to $15.4 million for 2008. The increase was due to additional product sales and development expenses relating to our continuing performance obligations under development and collaboration agreements entered into during 2008. Research and development expense totaled $14.3 million compared to $19.6 million in 2008. Changes in research and development expense included lower salaries, consulting, and facility costs. Selling, general and administrative expense totaled $35.2 million in 2009 compared to $27.7 million in 2008, with the change primarily due to additional selling, marketing, and international business development costs, including increased share-based compensation. As of December 31, 2009, the Company had $28.0 million in cash and marketable securities, and $2.4 million in restricted cash. In January 2010, the Company completed a follow-on public offering, selling an aggregate of approximately 4.0 million shares of its common stock for net proceeds of approximately $33.1 million, after deducting underwriting discounts, commissions and estimated offering expenses.
