About NuVasive

NuVasive is a medical device company focused on the design, development and marketing of products for the surgical treatment of spine disorders. The Company's product portfolio is focused on applications in the over $3.6 billion U.S. spine fusion market. The Company's current principal product offering includes a minimally disruptive surgical platform called Maximum Access Surgery, or MAS(TM), as well as a growing offering of cervical and motion preservation products.

The MAS platform offers advantages for both patients and surgeons such as reduced surgery and hospitalization time and faster recovery. MAS combines three categories of current product offerings: NeuroVision(R) a proprietary software-driven nerve avoidance system; MaXcess(R) a unique split-blade design retraction system; and specialized implants, like SpheRx(R) and CoRoent(R), that collectively minimize soft tissue disruption during spine surgery while allowing maximum visualization and surgical reproducibility. NuVasive's product offering is also focused on cervical internal fixation products and its R&D pipeline emphasizes both MAS and motion preservation.

The potential risks and uncertainties that could cause actual growth and results to differ materially include, but are not limited to: the uncertain process of seeking regulatory approval or clearance for NuVasive's products or devices, including risks that such process could be significantly delayed (particularly with respect to the ongoing clinical trial for NeoDisc(TM)); the possibility that the FDA may require significant changes to NuVasive's products or clinical studies; the risk that the Company's financial projections may prove incorrect because of unexpected difficulty in generating sales or achieving anticipated profitability; the risk that products may not perform as intended and may therefore not achieve commercial success; the risk that competitors may develop superior products or may have a greater market position enabling more successful commercialization; the risk that additional clinical data may call into question the benefits of NuVasive's products to patients, hospitals and surgeons; and other risks and uncertainties more fully described in NuVasive's press releases and periodic filings with the Securities and Exchange Commission.
