On a sequential basis, revenue increased 8% from $18.7 million in the third quarter of 2009. Gross profit for the fourth quarter of 2009 was $7.3 million, representing a 36% gross margin, compared to a gross profit of $1.2 million, or a 10% gross margin, for the fourth quarter of 2008. On a sequential basis, gross profit increased 26% from $5.8 million in the third quarter of 2009.

Operating loss for the fourth quarter of 2009 was $12.0 million, a 56% improvement compared to operating loss of $27.4 million in the fourth quarter of 2008. Total operating expenses were $19.3 million in the fourth quarter of 2009, compared to $28.6 million in the fourth quarter of 2008. The fourth quarter of 2008 included a non-recurring restructuring and impairment charge of $8.2 million. Net loss for the fourth quarter of 2009 was $14.9 million, or $0.42 per share, compared to a net loss of $29.2 million, or $1.05 per share, for the fourth quarter of 2008.

“2009 was a year of strong commercial execution and growth for Insulet, and I am extremely proud of all that we accomplished,” said Duane DeSisto, President and Chief Executive Officer of Insulet. “Our focus on efficiency and expansion was evident as we significantly increased our revenue, improved gross profit, reduced our operating loss and strengthened our balance sheet. Last year, we launched our new PDM with enhanced features and this year we are moving forward with both the next generation OmniPod and PDM with integrated continuous glucose monitoring. We will continue to deliver results for our shareholders in 2010, as we drive further adoption of the easy-to-use OmniPod System in the US and, with our partner Ypsomed, expand into new markets around the world.”

Full Year Results

For the year ended December 31, 2009, revenue increased 83% to $66.0 million from $36.1 million for the year ended December 31, 2008. Gross profit for the full year 2009 was $18.3 million, representing a 28% gross margin, as compared to a gross loss of $4.6 million, or a (13%) gross margin, in 2008.

Operating loss for the year ended December 31, 2009 was $59.4 million, an improvement of 34% as compared to an operating loss of $89.3 million in the year ended December 31, 2008. Total operating expenses were $77.7 million for the full year 2009, compared to $84.8 million for the full year 2008. Net interest expense was $20.2 million in 2009, compared to $5.4 million in 2008. The increase mainly reflects: (a) $11.1 million in cash and non-cash interest on the Company’s credit facility originally entered into in March 2009 and amended in September 2009, (b) $2.2 million related to the Company’s adoption of FASB Staff Position APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement) and (c) $2.1 million of additional cash interest on the 5.375% Notes. Net loss for the year ended December 31, 2009 was $79.5 million, or $2.68 per share, compared to $94.8 million, or $3.43 per share, for the year ended December 31, 2008.

As of December 31, 2009, the Company had cash and cash equivalents of $128.0 million compared to $56.7 million at December 31, 2008.

Recent Highlights

• Two recently published clinical studies highlight how the tubing-free design of the OmniPod System helps people better control their diabetes. In one study, published in the most recent issue of Infusystems USA, researchers at Albany College of Pharmacy and Health Sciences and The Endocrine Group concluded that the OmniPod System improved blood glucose control in diabetes patients who previously received insulin through multiple daily injections. Study investigators noted the benefits of a tubing-free insulin pump, which can help patients overcome their fear of insertion sets or unsightly tubing and achieve the clinical benefits of insulin pump therapy. In a separate study, published in the Journal of Diabetes Science and Technology, researchers at Sansum Diabetes Research Institute and University of California, Santa Barbara concluded that changing the height of a conventional insulin pump in relation to its tubing and infusion set can significantly impact expected insulin delivery rates. The study noted that the tubing-free OmniPod System, with its integrated cannula, was the least affected by pumping orientation and direction. Previous research has demonstrated how disconnecting from a traditional infusion set impacts glucose levels. These studies collectively offer insight into how the tubing-free OmniPod System may help patients reduce their glycemic variability and better control their diabetes.

• In January 2010, the Company entered into an exclusive agreement with Ypsomed AG for the distribution of the OmniPod System in nine countries across Europe as well as China and Australia. Under the agreement, Ypsomed will have the exclusive right to promote, advertise, market, distribute and sell the OmniPod System in the eleven countries covered by the agreement, beginning in Germany, France and the United Kingdom in mid-2010. At the minimum annual purchase levels called for in the agreement, the Company would recognize in excess of $100 million in revenue over its five year term. The minimum annual purchase levels are heavily weighted towards the final years of the term; accordingly, it is expected that the Company’s 2010 revenues under the agreement will not be material.

• In October 2009, the Company sold 6.9 million shares of its common stock in a public offering at a price of $10.25 per share resulting in net proceeds to the Company of approximately $66.1 million.

Guidance

For the full year 2010, the Company is estimating revenue to be in the range of $90 to $100 million and its operating loss to be in the range of $30 to $40 million. The Company is estimating revenue of $20 to $21 million in the first quarter of 2010.
