Endologix Reports 20% Revenue Growth for the Third Quarter 2012

Updates 2012 Revenue Guidance to 25% to 27% Growth

IRVINE, Calif. (October 25, 2012) - Endologix, Inc. (NASDAQ: ELGX), developer and marketer of innovative treatments for aortic disorders, today announced financial results for the three and nine months ended September 30, 2012.

John McDermott, Endologix President and Chief Executive Officer, said, “During the third quarter we continued to gain market share, achieving 20% revenue growth over the prior year. There continues to be strong interest in the AFX® Endovascular AAA System and our new product pipeline, which will further expand our market opportunity. During the quarter we made good progress advancing our new products and expanding our global sales force and remain on track to achieve our goals for the remainder of the year.”

Mr. McDermott added, “We recently announced the settlement of a patent dispute with Cook Incorporated. We are pleased to put this lawsuit behind us and eliminate the ongoing costs and uncertainty of litigation.”

Financial Results

Global revenue in the third quarter of 2012 was $26.7 million, a 20% increase from $22.3 million in the same quarter of 2011. For the nine months ended September 30, 2012, total revenue increased 28% to $76.7 million, compared to $60.0 million for the nine months ended September 30, 2011.

U.S. revenue in the third quarter of 2012 was $21.3 million, a 5% increase compared with $20.3 million in the third quarter of 2011, which was largely driven by the continued adoption of the AFX system and the expansion of the U.S. sales force through the addition of clinical specialists. International revenue was

$5.4 million, a 170% increase compared to $2.0 million in the third quarter of 2011. The international sales increase is attributable to a transition to a direct sales organization in Europe, beginning in September 2011, and improved penetration in the Latin American and Japanese markets.

Gross profit was $20.3 million in the third quarter of 2012, which represents a gross margin of 76%. This compares with gross margin of 78% in the third quarter of 2011. Gross profit was $58.6 million for the nine months ended September 30, 2012, representing a gross margin of 76%. This compares with gross margin of 78% for the nine months ended September 30, 2011. Lower gross margins for the three and nine months ended September 30, 2012 are the result of a greater proportion of international sales to global sales in both periods, and royalty payments to CR Bard Inc. that had not yet commenced in the corresponding 2011 periods.

Total operating expenses were $27.2 million in the third quarter of 2012, compared to $22.6 million in the third quarter of 2011. Total operating expenses for the nine months ended September 30, 2012 were $74.8 million, compared with $61.8 million for the nine months ended September 30, 2011. Operating expense for the three and nine months ended September 30, 2012 include a $5.0 million charge related to the Company's previously announced settlement agreement with Cook Incorporated (“Cook”).

Marketing and sales expenses were $12.7 million in the third quarter of 2012, an increase from $12.3 million in the prior year period. For the nine months ended September 30, 2012, marketing and sales expenses were $38.9 million, an increase from $33.2 million in the prior year period. These increases were driven primarily by costs associated with building the direct sales organization in Europe.

Research and development expenses were $3.1 million in the third quarter of 2012, a decrease from $3.6 million in the prior year period.  For the nine months ended September 30, 2012, research and development expenses were $11.9 million, a decrease from $12.8 million in the prior year period.  The decrease in the third quarter of 2012 primarily reflects decreasing Ventana® Fenestrated System development activities, as the device progresses towards production and European commercialization. The decrease for the nine months ended September 30, 2012 largely represents the aforementioned Ventana progression, partially offset by a $1.0 million charge in the current period to acquire an exclusive patent license.

Clinical and regulatory affairs expenses were $1.5 million in the third quarter of 2012, an increase from $1.2 million in the prior year period.  For the nine months ended September 30, 2012, clinical and regulatory affairs expenses were $4.7 million, an increase from $3.0 million in the prior year period.  These increases were primarily driven by the continued enrollment and follow-up costs associated with

PEVAR and Ventana clinical trials, and various costs to achieve CE Mark approval of Ventana and the Nellix® EndoVascular Aneurysm Sealing System.

General and administrative expenses were $4.9 million in the third quarter of 2012, up from $4.2 million in the same period in 2011. For the nine months ended September 30, 2012, general and administrative expenses were $13.8 million, up from $11.1 million in the same period last year. These increases were driven primarily by expenses associated with the establishment of European operations.

Endologix reported a net loss for the third quarter of 2012 of $(5.9) million, or $(0.10) per share, compared with a net loss of $(6.6) million, or $(0.12) per share, for the third quarter of 2011. The third quarter 2012 loss includes a $1.0 million non-cash credit for the reduction of the contingent liability related to the Nellix acquisition, and a $5.0 million charge for the Cook settlement. Endologix reported Adjusted Net Loss (non-GAAP and defined below) for the third quarter of 2012 of $(1.8) million, or $(0.03) per share, compared with an Adjusted Net Loss (non-GAAP and defined below) for the third quarter of 2011 of $(3.9) million, or $(0.07) per share.

For the nine months ended September 30, 2012, Endologix reported a net loss of $(29.3) million, or $(0.49) per share, compared to a net loss of $(25.1) million, or $(0.44) per share, for the nine months ended September 30, 2011.

Discussion of Non-GAAP Financial Measures

The Endologix management believes that the non-GAAP measures of (1) "Adjusted Net Income (Loss)", (2) "Adjusted Net Income (Loss) Per Share”, and (3) “Adjusted EBITDA'" measures enhance an investor's overall understanding of Endologix's financial and operating performance and its future prospects by (i) being more reflective of core operating performance; (ii) providing enhanced measures of progress towards generating positive cash flows from core operations; and (iii) being more comparable with financial results over various periods.  Endologix management uses these financial measures for strategic decision making, forecasting future financial results, and evaluating current period financial and operating performance.

Adjusted Net Income (Loss) and Adjusted Net Earnings (Loss) per Share Definitions:

"Adjusted Net Income (Loss)" is a non-GAAP measure defined by Endologix as net income (loss) under GAAP, excluding: (i) all effects arising from applicable business combination accounting under GAAP for its acquisition of Nellix; (ii) settlement costs; (iii) contract termination fees and business acquisition expenses; and (iv) business development expenses.

In the three months ended September 30, 2012, this GAAP adjustment to net loss specifically represents: (i) the fair value adjustment to the liability for contingent payments (in the form of Endologix common stock) to the former shareholders of Nellix and (ii) the cost of the Cook settlement.

In the nine months ended September 30, 2012, this GAAP adjustment to net loss specifically represents: (i) the fair value adjustment to the liability for contingent payments to the former shareholders of Nellix; (ii) the cost of the Cook settlement; (iii) expenses associated with the acquisition of its distributor in Italy; and (iv) the cost of an exclusive patent.

In the three months ended September 30, 2011, this GAAP adjustment to net loss specifically represents: (i) the fair value adjustment to the liability for contingent payments (in the form of Endologix common stock) to the former shareholders of Nellix; and (ii) distribution agreement termination fees with a pan-European distributor.

In the nine months ended September 30, 2011, this GAAP adjustment to net loss specifically represents: (i) the fair value adjustment to the liability for contingent payments to the former shareholders of Nellix; and (ii) distribution agreement fees with a pan-European distributor and a separate distributor in Italy.

In future periods, Adjusted Net Income (Loss) will continue to exclude: (i) the fair value adjustments to the liability for contingent payments to the former shareholders of Nellix (in the form of Endologix common stock); (ii) contract termination fees; (iii) the effects of acquisitions or other business development transactions; and (iv) other non-recurring expenses or income, as described by Endologix.

"Adjusted Net Income (Loss) per Share" is a non-GAAP measure defined by Endologix as Adjusted Net Income (Loss) divided by average shares outstanding (basic and diluted, as applicable under GAAP).

"GAAP" is generally accepted accounting principles in the United States.

Adjusted EBITDA Definition:
