SAN DIEGO, Oct. 27 /PRNewswire-FirstCall/ -- NuVasive, Inc. (Nasdaq: NUVA), a medical device company focused on developing products for minimally disruptive surgical treatments for the spine, announced today third quarter financial results for the period ended September 30, 2005.

The Company reported third quarter revenues of $15.1 million, a 48.6% increase over the $10.2 million for the third quarter of 2004 and consistent with the $15.0 million for the second quarter of 2005. Maximum Access Surgery (MAS) revenues for the third quarter of 2005 were $11.7 million compared to $8.0 million for the third quarter of 2004 and $12.6 million for the second quarter of 2005.

Gross profit for the third quarter of 2005 was $11.8 million with a gross margin of 78.2%, compared with a gross profit of $7.6 million with a gross margin of 74.2% in the third quarter of 2004. For the second quarter of 2005, gross profit was $11.9 million with a gross margin of 78.9%.

The continued strong gross margin for the third quarter of 2005 was due primarily to the revenue mix of 77% MAS revenues and 23% classic fusion revenues and to the mix of products within MAS, specifically NeuroVision(R) and MaXcess(R) disposables and specialized implants. MAS products generally have a higher margin than classic fusion products; however, due to the introduction of new products within classic fusion, this category is increasingly composed of higher margin products such as our cervical plate, SmartPlate(R) Gradient CLP(TM).

Total operating expenses for the third quarter of 2005 were $30.6 million, compared with $10.6 million in the third quarter of 2004 and $16.3 million in the second quarter of 2005. The quarter-over-quarter and year-over-year increases are due primarily to (i) in-process research and development costs of $12.9 million incurred in the third quarter of 2005 related to acquisition activity, (ii) additional sales and marketing expenses related to the Company's program to transition its sales force toward exclusivity; and (iii) continued investment in the Company's next generation MAS products, accelerated surgeon and sales representative training, and marketing and trade show related costs. Operating expenses on a non-GAAP basis for the third quarter of 2005 were $16.9 million, compared with $9.3 million in the third quarter of 2004 and $15.0 million in the second quarter of 2005.

On a GAAP basis for the three-month period ended September 30, 2005, the Company reported a net loss of $18.5 million or $0.74 per share. On a non-GAAP basis, third quarter net loss, was $4.8 million, or $0.19 per share. Non-GAAP net loss consists of GAAP net loss excluding, amortization of acquired intangible assets, stock-based compensation, and in-process research and development charges.

Cash, cash equivalents and short-term investments were $25.0 million at September 30, 2005.

New Products

During the third quarter of 2005, NuVasive launched a total of five new products, completing the Company's planned launch of nine new products in 2005. The five products launched in the third quarter included:

* MaXcess II - an enhancement of the Company's current MaXcess system, with the addition of several features to allow for greater access to the spine, including superior and inferior blades that "kick-out" at an angle to spread the tissue closest to the pathology point. MaXcess II also incorporates the Company's NeuroVision nerve avoidance technology within the posterior retraction blade, allowing surgeons to dynamically test for surrounding nerves during the entire procedure;
* The CoRoent(TM) Large Contoured Implant and CoRoent XLR - designed to allow for simplicity of surgeon placement and proper anatomical fit in the spine. These products are complementary to the CoRoent system designed in response to the demand from spine surgeons for implants with superior anatomical fit that are simple to position and align;
* NeuroVision software upgrade / harness and dual electrodes - incorporates a new graphical user interface that allows for greater ease of use by the surgical staff and improved surface electrodes that relay muscle activity to the NeuroVision nerve monitoring system; and
* ExtenSure - an interspinous dynamic stabilization and fusion system allowing decompression through a more natural restoration of the spinal anatomy. ExtenSure's primary indication is for lumbar spinal stenosis.

The four additional products launched in the first half of 2005 include the SpheRx(R) Dual Ball Rod (DBR(TM)) Minimally Disruptive Fixation System, SmartPlate Gradient CLP, Insulated Pedicle Access System (I-PAS(TM)) and CoRoent Large Tapered.

During the third quarter, the Company acquired technology and assets from Pearsalls Limited, including a cervical disc replacement device called NeoDisc. NeoDisc is an investigational device offering NuVasive a first to U.S. market potential with a nucleus-like device designed to preserve motion in the cervical region of the spine and fill the gap between pre-surgical treatment and Total Disc Replacement (TDR) or spine fusion. NuVasive believes NeoDisc could be attractive for use in broad indications and pathologies because it is easily revisable and is intended to involve a relatively simple surgical placement procedure. The Company also acquired assets and technology from Riverbend Design LLC useful in the development of dynamic stabilization products. The Company launched its first product using this technology, ExtenSure, during the quarter.

Alexis V. Lukianov, Chairman and Chief Executive Officer, said, "Our revenues for the third quarter were in line with our expectations and we remain on track to meet our previously stated 2005 full year revenue target in the range of $61 million to $62 million. The initiative to establish an exclusive sales force, including both independent and direct sales agents, continues on track. At the end of the third quarter, 30% of our sales force was exclusive to NuVasive, up from 21% at the end of the second quarter. "

Mr. Lukianov continued, "We are particularly pleased with the five new products launched during the quarter, including ExtenSure from the Riverbend acquisition. Our acquisition of the NeoDisc investigational device yielded an IDE application on October 21, 2005 and we look forward to formalizing the criteria for the anticipated clinical study. It is our continuing ability to introduce innovative products that places NuVasive at the forefront of providing surgeons with the latest minimally disruptive spine surgery technology."

Non-GAAP Information

Management uses certain non-GAAP financial measures, such as non-GAAP gross profit, non-GAAP operating expenses, non-GAAP net loss and non-GAAP net loss per share, which exclude the following charges: (i) stock based compensation, (ii) charges directly related to acquisition transactions such as in-process research and development, amortization of the acquired technology assets and certain other non-recurring internal costs incurred as a result of the transaction, and (iii) certain other amounts related to non- recurring events. Management has determined that such costs should not be considered in evaluating the continuing operations of the Company because management believes they are not indicative of the ongoing business operations. Therefore, management calculates the non-GAAP financial measures provided in this earnings release excluding these costs and uses these non- GAAP financial measures to enable it to analyze further and more consistently the period-to-period financial performance of its core business operations. Management believes that although it is important for investors to understand GAAP measures, providing investors with these non-GAAP measures gives them additional important information to enable them to assess, in a way management assesses, the Company's current and future continuing operations. These non- GAAP measures are not in accordance with, or an alternative for, GAAP, and may be different from non-GAAP measures used by other companies.
