Lowe, Hansen Medical’s interim Chief Executive Officer. “We will continue to develop the clinical experience and utilization of our core technology, and expand our catheter and technology offerings toward the long-term opportunity of making robotics the standard of care for intravascular procedures.

Fourth Quarter of 2013 Financial Results

Total revenue for the fourth quarter ended December 31, 2013 increased 29% to $5.6 million, compared to revenue of $4.3 million in the same period in 2012. The Company commercialized six systems in the quarter (5 Magellan and 1 Sensei). The Company uses the term “commercialized” to refer to revenue-generating system transactions, including rental transactions. The Company sold 600 catheters in the fourth quarter of fiscal 2013, down 29% year-over-year. The decrease was driven primarily by hospitals’ and distributors’ intentions to manage inventory at lower levels at the end of the calendar year, despite continued growth in procedures. Physicians performed an estimated 815 robotic procedures in the fourth quarter of 2013, up 8% year-over-year.

Gross profit in the fourth quarter of fiscal 2013 increased 29% to $1.1 million, or 20% of sales, compared to $0.9 million, or 20% of sales, last year. Fourth quarter gross margin was negatively impacted by one time price discounts on the strategic sales of two systems in two new international markets.

Research and development expenses for the fourth quarter were $3.7 million, compared to $3.5 million for same period in 2012. The increase of $0.2 million is primarily due to incremental costs associated with continued new product development and clinical program initiatives designed to expand the utilization of our platform.

Selling, general and administrative expenses for the fourth quarter were $8.0 million, compared to $6.8 million for the same period of 2012. The increase of $1.2 million is primarily due to costs related to the expansion of our global sales organization and marketing activities in the quarter.

Net loss for the fourth quarter of 2013 was $11.9 million, or $0.12 per share compared to net income of $9.6 million, or $0.15 per share, in the fourth quarter of 2012. Net loss for the fourth quarter of 2013 included total non-cash stock compensation expenses of $1.3 million compared to $0.6 million in the fourth quarter of 2012. Net income for the fourth quarter of 2012 included a $20.0 million gain on licensing of intellectual property to Intuitive Surgical. Weighted average shares outstanding to compute diluted net income or loss per share were 96.8 million for the fourth quarter compared to 65.9 million in the fourth quarter of 2012.

Cash, cash equivalents, short-term investments and restricted cash were $35.3 million as of December 31, 2013, down $11.8 million quarter-over-quarter from the $47.1 million balance as of September 30, 2013.

Fiscal Year 2013 Financial Results

Total revenue for the year ended December 31, 2013 was $17.0 million, a decrease of 4% compared to $17.6 million in fiscal year 2012. The Company commercialized 14 systems in 2013 (9 Magellan and 5 Sensei), including two rental systems, compared to 13 systems in the prior year period (4 Magellan and 9 Sensei). Revenue in fiscal year 2012 included approximately $2.6 million on five systems that were sold prior to 2012 (1 Magellan and 4 Sensei). Catheter sales increased 2% to 2,857 in fiscal year 2013, compared to 2,807 in the prior year period, and physicians performed an estimated 3,210 procedures in 2013, a 19% increase compared to estimated procedures of 2,688 in 2012.

Gross profit for fiscal year 2013 declined 3% to $3.5 million, or 21% of sales, compared to gross profit of $3.6 million, or 21% of sales in 2012. Gross profit for the year was negatively impacted by one time price discounts on the strategic sales of two systems in two new international markets, partially offset by continuing efforts to lower product manufacturing costs.

Total operating expenses for 2013 were $52.4 million, which included a $4.5 million loss on settlement of litigation compared to 2012 operating expenses of $42.1 million. Excluding the $4.5 million settlement charge, the $5.8 million increase over prior year is due primarily to additional litigation and other legal expenses in the current year of approximately $2.8 million, additional costs associated with the Company’s development of global sales organization, and other marketing activities of approximately $1.4 million, and $1.5 million of insurance reimbursement proceeds received, and recorded as a reduction to expense, in 2012.

The Company reported a net loss of $55.7 million, or $0.70 per share, in fiscal year 2013, compared to a net loss of $22.1 million, or $0.35 per share in the prior year. Fiscal year 2013 results included $4.9 million of non-cash stock compensation expense and a loss of $1.9 million on the extinguishment of debt. The Company’s net loss in 2012 included non-cash stock compensation expense of $2.9 million, and a gain $20.0 million on the licensing of intellectual property to Intuitive Surgical. Weighted average shares outstanding used to compute diluted net loss were 79.1 million for fiscal year 2013 compared to 62.5 million for fiscal year 2012.

Expected Exercise of Series A Warrants

The FDA clearance of the Magellan 6Fr Robotic Catheter triggered the required exercise period for approximately $14 million of Series A warrants that were issued as part of the private placement of stock and warrants that was announced on July 31, 2013. The Company issued Series A warrants to purchase approximately 11.4 million shares of common stock with a per share exercise price of $1.23 as part of the private placement transaction. The holders of these Series A warrants are required to exercise the warrants, upon 15 days’ notice of the FDA clearance of the 6Fr catheter, which the Company provided to holders on February 11. Any

About Hansen Medical, Inc.

Hansen Medical, Inc., based in Mountain View, California, is a global leader in intravascular robotics, developing products and technology designed to enable the accurate positioning, manipulation and control of catheters and catheter-based technologies. The Company’s Magellan™ Robotic System, 9Fr Magellan™ Robotic Catheter, Magellan™ 6Fr Robotic Catheter, and related accessories are intended to facilitate navigation to anatomical targets in the peripheral vasculature and subsequently provide a conduit for manual placement of therapeutic devices. The Magellan 9Fr Robotic Catheter has undergone both CE marking and 510(k) clearance and is commercially available in the European Union, and the U.S. The Magellan 6Fr Robotic Catheter has undergone 510(k) clearance in the U.S. and is in limited release for the next several months in anticipation of more wide-scale commercially availability later in 2014. In the European Union, the Company’s Sensei^® X Robotic Catheter System and Artisan^® and Artisan Extend^® Control Catheters are cleared for use during electrophysiology (EP) procedures, such as guiding catheters in the treatment of atrial fibrillation (AF), and the Lynx^® Robotic Ablation Catheter is cleared for the treatment of AF. This robotic catheter system is compatible with fluoroscopy, ultrasound, 3D surface map and patient electrocardiogram data. In the U.S., the Company’s Sensei X Robotic Catheter System and Artisan and Artisan Extend Control Catheters are cleared by the U.S. Food and Drug Administration for manipulation and control of certain mapping catheters in EP procedures. In the U.S., the Sensei X Robotic Catheter System is not approved for use in guiding ablation procedures; this use remains experimental. The U.S. product labeling therefore provides that the safety and effectiveness of the Sensei X Robotic Catheter System and Artisan and Artisan Extend Control Catheter for use with cardiac ablation catheters in the treatment of cardiac arrhythmias, including AF, have not been established.
