News Release

SAN DIEGO, March 6, 2014 /PRNewswire/ -- Tandem Diabetes Care®, Inc. (NASDAQ: TNDM), a medical device company and manufacturer of the t:slim® Insulin Pump, today reported its financial results for the quarter and year ended December 31, 2013.

For the year ended December 31, 2013, sales were $29.0 million compared to $2.5 million for the same period of 2012.  Commercial sales of the t:slim Insulin Pump and related supplies commenced in August of 2012.  Sales for the fourth quarter of 2013 were $10.2 million, compared to $2.3 million for the same period of 2012.  Sales for the fourth quarter of 2013 also grew 32 percent sequentially over the third quarter of 2013.  These increases in sales were driven by continued growth of the t:slim Insulin Pump customer base.

"We experienced tremendous growth in 2013 and achieved positive gross margins in our first full year of commercialization," said Kim Blickenstaff, President and Chief Executive Officer of Tandem Diabetes Care. "We believe these are key accomplishments that establish a firm foundation from which we can expand market awareness and adoption of the t:slim Insulin Pump, and strengthen our business operations."

For the year ended December 31, 2013, gross margin was 21 percent compared to a negative gross margin of -54 percent for the same period of 2012.  Gross margin for the fourth quarter of 2013 was 12 percent, compared to a negative gross margin of -20 percent for the fourth quarter of 2012.  The gross margins for the year and quarter ended December 31, 2013 were negatively impacted by approximately $1.3 million of costs directly related to the previously announced voluntary cartridge recall that the Company initiated in January 2014.  The total direct cost of the recall is expected to be $1.6 million, consisting of costs associated with the return and replacement of affected cartridges in the field and the write-off of cartridges within the Company's inventory.

For the year ended December 31, 2013, operating expenses totaled $55.6 million compared to $31.7 million for the same period of 2012.  For the fourth quarter of 2013, operating expenses totaled $17.7 million compared to $8.0 million for the same period of 2012.  The increases in operating expenses are primarily associated with the expansion of commercial operations and non-cash, stock-based compensation. Operating expenses included non-cash, stock-based compensation for the year and quarter ended December 31, 2013 of $4.5 million and $2.7 million, respectively, compared to $246,000 and $49,000 for the comparable periods of 2012.

For the year ended December 31, 2013, operating loss was $49.4 million compared to $33.0 million for the same period of 2012. Operating loss for the fourth quarter of 2013 was $16.5 million, compared to $8.4 million for the same period of 2012.  

As of December 31, 2013, the Company had $129.5 million in cash, cash equivalents and short-term investments.

For the year ending December 31, 2014, the Company estimates that sales will be in the range of $48.0 million to $54.0 million.
