Notes to Consolidated Financial Statements

(Unaudited)

1. Description of Business

TranS1 Inc., a Delaware corporation (the “Company”), was incorporated in May 2000 and is headquartered in Wilmington, North Carolina. The Company is a medical device company focused on designing, developing and marketing products to treat degenerative conditions of the spine affecting the lower lumbar region. The Company operates in one business segment. The Company currently markets the AxiaLIF® family of products for single and two level lumbar fusion, the VEO^TM lateral access and interbody fusion system, the Vectre™ lumbar posterior fixation system and Bi-Ostetic^TM bone void filler, a biologics product. All of the Company’s AxiaLIF products are delivered using its pre-sacral approach. The Company also markets products that may be used with its surgical approach, including bowel retractors, a bone graft harvesting system and additional discectomy tools. The AxiaLIF 1L product was commercially released in January 2005. The AxiaLIF 2L™ product was commercially released in Europe in the fourth quarter of 2006 and in the United States in the second quarter of 2008. The AxiaLIF 2L product was discontinued in 2010 after the Company launched its AxiaLIF 2L+™ product in July 2010. The Company commercially launched its next generation Vectre facet screw system in April 2010. In the first quarter of 2010, the Company entered into an agreement to distribute Bi-Ostetic bone void filler, a biologics product. The Company commercially launched its AxiaLIF 1L+ product in September 2011. The Company commercially launched its VEO lateral access and interbody fusion system in November 2011 in the United States and in July 2012 in the European Union. The Company sells its products through a direct sales force, independent sales agents and independent distributors.

The Company has forty-five issued United States patents, fourteen pending patent applications or provisional patent applications in the United States, eight issued European patents, seven issued Japanese patents, and seven foreign patent application families as counterparts of U.S. cases. The issued and pending patents cover, among other things, (i) the Company’s method for performing trans-sacral procedures in the spine, including diagnostic or therapeutic procedures, and trans-sacral introduction of instrumentation or implants, (ii) apparatus for conducting these procedures including access, disc preparation and implantation including the current TranS1 instruments individually and in kit form, (iii) implants for fusion and motion preservation in the spine, and (iv) a lateral access and interbody fusion system.

The Company owns eight trademark registrations in the United States, nine trademark registrations in the European Union and two registered trademarks in Canada. The Company also owns two pending trademark applications in the United States, four pending trademark applications in China and one pending trademark application in the European Union.

On September 26, 2011, the Company completed a public offering of 6,200,000 shares of its common stock at an offering price of $3.25 per share. The offering resulted in aggregate proceeds to the Company of approximately $18.2 million, net of underwriting discounts, commissions and offering expenses, and has been included in stockholders' equity as common stock and additional paid-in capital. At September 30, 2012 and December 31, 2011, there were 27,274,823 and 27,244,059 shares of common stock issued and outstanding, respectively, and there were no shares of preferred stock issued and outstanding.

5

The Company is subject to a number of risks similar to other similarly-sized companies in the medical device industry. These risks include, without limitation, acceptance and continued use of the Company’s products by surgeons, the lack of clinical data about the efficacy of these products, uncertainty of reimbursement from third-party payors, cost pressures in the healthcare industry, competitive pressures from substitute products and larger companies, the historical lack of profitability, the dependence on key employees, regulatory approval and market acceptance for new products, compliance with complex and evolving healthcare laws and regulations, uncertainty surrounding the outcome of the matters relating to the subpoena issued to the Company by the Department of Health and Human Services, Office of Inspector General, the reliance on a limited number of suppliers to provide these products, changes in economic conditions, the ability to effectively manage a sales force to meet the Company’s objectives and the ability to conduct successful clinical studies.

2. Basis of presentation

The Company has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC. The consolidated financial statements are unaudited and should be read in conjunction with the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2011. The accompanying unaudited interim consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of the Company’s management, necessary for a fair statement of the Company’s consolidated financial position, results of operations and cash flows for the periods presented. These principles require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The principal estimates relate to accounts receivable reserves, inventory reserves, stock-based compensation, accrued expenses and income tax valuations. Actual results could differ from those estimates. The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. All intercompany accounts and transactions have been eliminated in consolidation.

Impact of Recently Issued Accounting Standards

In May 2011, the Financial Accounting Standard Board (“FASB”)issued new authoritative guidance to provide a consistent definition of fair value and ensure that fair value measurements and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. This guidance changes certain fair value measurement principles and enhances the disclosure requirements for fair value measurements. This guidance was effective for interim and annual periods beginning after December 15, 2011 and is applied prospectively. The Company implemented this guidance in the first quarter of 2012 and it did not have a material impact on its financial statements.

6

In June 2011, the FASB issued guidance on the presentation of comprehensive income. This guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity and requires the presentation of other comprehensive income in a single continuous statement, or in two separate, but consecutive, statements.This guidance was effective for fiscal years and interim periods beginning after December 15, 2011. The Company implemented this guidance in the first quarter of 2012 and it did not have a material effect on its financial statements.

3. Income Taxes

No provisions for federal or state income taxes have been recorded as the Company has incurred net operating losses since inception.

4. Net Loss Per Common Share

Basic net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding. Diluted net loss available to common stockholders per common share is computed by dividing net loss by the weighted average number of common shares and dilutive potential common share equivalents then outstanding. The Company’s potential dilutive common shares, which consist of shares issuable upon the exercise of stock options, have not been included in the computation of diluted net loss per share for all periods as the result would be anti-dilutive.

The following table sets forth the potential shares of common stock that are not included in the calculation of diluted net loss per share as the result would be anti-dilutive as of the end of each period presented:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2012		2011		2012		2011
Weighted average stock options outstanding		3,409,083		2,790,581		3,224,660		2,546,090

5. Cash, Cash Equivalents and Investments

The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents include money market treasury funds. Short-term investments consist of U.S. agency backed debt instruments.

At September 30, 2012, the Company held certain assets that are required to be measured at fair value on a recurring basis. These assets include available for sale securities classified as cash equivalents. Accounting Standards Codification 820-10 requires the valuation of investments using a three-tiered approach, which requires that fair value measurements be classified and disclosed in one of three tiers. These tiers are: Level 1, defined as quoted prices in active markets for identical assets or liabilities; Level 2, defined as valuations based on observable inputs other than those included in Level 1, such as quoted prices for similar assets and liabilities in active markets, or other inputs that are observable or can be corroborated by observable input data; and Level 3, defined as valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants.

9. Contingencies

In October 2011, the Company received a subpoena issued by the Department of Health and Human Services, Office of Inspector General, under the authority of the federal healthcare fraud and false claims statutes. The subpoena seeks documents for the period January 1, 2008 through October 6, 2011. The Company is cooperating with the government’s request and is in the process of responding to the subpoena. The Company and its counsel have met with representatives from the government several times during the past four months and continue to work toward a conclusion to this matter. The Company is unable to predict what action, if any, might be taken in the future by the Department of Health and Human Services, Office of Inspector General or other governmental authorities as a result of the matters related to this subpoena or what impact, if any, the outcome of these matters might have on the Company’s consolidated financial position, results of operations, or cash flows. No claims have been made against the Company at this time. The Company’s liability, if any, resulting from this investigation cannot be estimated and as such, the Company has not recorded any liability within the condensed consolidated financial statements in relation to this matter.

In January 2012, the Company received notice that a class action lawsuit had been filed in the U.S. District Court Eastern District, North Carolina, on behalf of a class consisting of all persons other than the defendants who purchased the Company’s common stock between February 21, 2008 and October 17, 2011. The Company is in the process of responding to this lawsuit. The Company is unable to predict what impact, if any, the outcome of this matter might have on the Company’s consolidated financial position, results of operations, or cash flows.

10. Subsequent Event

In October 2012, the Company entered into a distribution agreement with Jiade Sunshine (“Jiade”), pursuant to which Jiade will be the exclusive distributor of AxiaLIF products in the People’s Republic of China, with the exception of Hong Kong, Macau and Taiwan. Under the agreement, Jiade placed an initial order for $1,360,000, which is expected to be shipped in the fourth quarter of 2012, and is required to place additional orders on at least an annual basis for a specified minimum amount of products over the life of the agreement.

Overview

We are a medical device company focused on designing, developing and marketing products to treat degenerative conditions of the spine affecting the lower lumbar region. We are committed to delivering minimally invasive surgical technologies that enhance patient clinical care while providing sustained value for our customers. Using our pre-sacral approach, a surgeon can access discs in the lower lumbar region of the spine through an incision adjacent to the tailbone and can perform an entire interbody fusion procedure through instrumentation that provides direct access to the intervertebral space. We developed our pre-sacral approach to allow spine surgeons to access and treat intervertebral spaces without compromising important surrounding soft tissue, nerves and bone structures. We currently market the AxiaLIF family of products for single and two level lumbar fusion, the VEO lateral access and interbody fusion system, the Vectre lumbar posterior fixation system and Bi-Ostetic bone void filler, a biologics product. We also market products that may be used with our AxiaLIF surgical approach, including bowel retractors, a bone graft harvesting system and additional discectomy tools. Our philosophy of continuous improvement is driven by ongoing research and development investment in our core technologies. We support this investment by diligently expanding, maintaining, and protecting our significant patent portfolio.

From our incorporation in 2000 through 2004, we devoted substantially all of our resources to research and development and start-up activities, consisting primarily of product design and development, clinical trials, manufacturing, recruiting qualified personnel and raising capital. We received 510(k) clearance from the FDA for our AxiaLIF 1L product in the fourth quarter of 2004, and commercially introduced our AxiaLIF 1L product in the United States in the first quarter of 2005. We received a CE mark to market our AxiaLIF 1L product in the European market in the first quarter of 2005 and began commercialization in the first quarter of 2006. We received a CE mark for our AxiaLIF 2L product in the third quarter of 2006 and began commercialization in the European market in the fourth quarter of 2006. We received FDA 510(k) clearance for our AxiaLIF 2L product and began marketing this product in the United States in the second quarter of 2008. The AxiaLIF 2L product was discontinued in 2010 after we launched our AxiaLIF 2L+ product in July 2010, for which we had received FDA 510(k) clearance in January 2010. We commercially launched our next generation Vectre facet screw system in April 2010. In the first quarter of 2010, we entered into an agreement to distribute Bi-Ostetic bone void filler, a biologics product. We commercially launched our AxiaLIF 1L+ product in September 2011, for which we had received FDA 510(k) clearance in March 2011. In 2010, we received 510(k) clearance for our VEO lateral access and interbody fusion system, which was commercially launched in November 2011 and in July 2012 we received a CE mark for our VEO lateral access and interbody fusion system and began commercialization in the European market. We currently sell our products through a direct sales force, independent sales agents and international distributors.

In March 2012, we announced that the Current Procedural Terminology (“CPT”) Editorial Panel, or the Panel, voted to approve an application for a new Category I CPT code, 22586, for L5/S1 spinal fusion utilizing our AxiaLIF implant when performing a pre-sacral interbody fusion. In addition, the Panel voted to establish a new Category III CPT code, 0309T, as an add-on code to the new Category I code for use with 22586 when performing L4/5 spinal fusion. The new CPT codes were announced on the American Medical Association’s website on March 2, 2012, and will become effective on January 1, 2013. The Medicare final rule was released in November 2012, which stated a valuation of the Category I CPT code 22586 for pre-sacral interbody single level spinal fusion at L5-S1, and will become effective January 1, 2013. This CPT code, which applies to our AxiaLIF 1L+ device, is a bundled lumbar arthrodesis procedure that includes bone graft, posterior instrumentation and fixation.

11

We rely on third parties to manufacture all of our products and their components, except for our nitinol nucleus cutter blades, which we manufacture at our facility in Wilmington, North Carolina. Our outsourcing partners are manufacturers that meet FDA, International Organization for Standardization or other internal quality standards, where applicable. We believe these manufacturing relationships allow us to work with suppliers who have the best specific competencies while we minimize our capital investment, control costs and shorten cycle times.

Since inception, we have been unprofitable. As of September 30, 2012, we had an accumulated deficit of $126.8 million.

We expect to continue to invest in sales and marketing infrastructure for our products in order to gain wider acceptance for them. We also expect to continue to invest in research and development and related clinical trials, and increase general and administrative expenses as we grow. As a result, we will need to generate significant revenue in order to achieve profitability.

On September 26, 2011, we completed a public offering of 6,200,000 shares of our common stock at an offering price of $3.25 per share. The offering resulted in aggregate proceeds to us of approximately $18.2 million, net of underwriting discounts, commissions and offering expenses.

Revenue

We generate revenue from the sales of our implants and disposable surgical instruments. We have two distinct sales methods. The first method is when implants and/or disposable surgical instruments are sold directly to hospitals or surgical centers for the purpose of conducting a scheduled surgery. Our sales representatives or independent sales agents hand deliver the products to the customer on or before the day of the surgery. The sales representative or independent agent is then responsible for reporting the delivery of the products and the date of the operation for proper revenue recognition. We recognize revenue upon the confirmation that the products have been used in a surgical procedure. The second sales method is for sales to distributors outside the United States. These transactions require the customer to send in a purchase order before shipment and the customer only has the right of return for defective products. We primarily recognize revenue upon the shipment of the product to distributors outside the United States. We expect that a substantial portion of our revenues will continue to be generated in the United States in future periods.

12

Cost of Revenue

Cost of revenue consists primarily of material and overhead costs related to our products, including reusable kit depreciation and product royalties. Overhead costs include facilities-related costs, such as rent and utilities.

Research and Development

Research and development expenses consist primarily of personnel costs within our product development, regulatory and clinical functions and the costs of clinical studies, product development projects and technology licensing costs. In future periods, we expect research and development expenses to grow as we continue to invest in basic research, clinical trials, product development and intellectual property.

Sales and Marketing

Sales and marketing expenses consist of personnel costs, sales commissions paid to our direct sales representatives and independent sales agents, and costs associated with physician training programs, promotional activities and participation in medical conferences.

General and Administrative

General and administrative expenses consist of personnel costs related to the executive, finance, business development, and human resource functions, as well as professional service fees, legal fees, accounting fees, insurance costs and general corporate expenses.

Other Income (Expense), Net

Other income (expense), net is primarily composed of interest earned on our cash, cash equivalents and available-for-sale securities and the gain or loss on disposal of fixed assets.

Results of Operations

Comparison of the Three Months Ended September 30, 2011 and 2012

Revenue Revenue decreased from $4.7 million in the three months ended September 30, 2011 to $3.2 million in the three months ended September 30, 2012. The $1.5 million decrease in revenue from 2011 to 2012 was primarily a result of a lower number of AxiaLIF cases performed in 2012, which was due primarily to physician reimbursement limitations and insurance denials for lumbar fusion surgery due to medical necessity. Domestically, sales of our AxiaLIF 1L and AxiaLIF 1L+ products decreased from $2.2 million in the three months ended September 30, 2011 to $1.2 million in the three months ended September 30, 2012, and sales of our AxiaLIF 2L+ products decreased from $1.3 million in the three months ended September 30, 2011 to $0.7 million in the three months ended September 30, 2012. In the three months ended September 30, 2012, average revenue per AxiaLIF case increased, primarily as a result of a price increase effective April 1, 2012, the release of new AxiaLIF products and penetration into existing cases by our other products. In the three months ended September 30, 2011 and 2012, we recorded 304 and 164 domestic AxiaLIF cases, respectively, including 88 AxiaLIF 2L+ cases in the three months ended September 30, 2011, and 46 AxiaLIF 2L+ cases in the three months ended September 30, 2012. During the three months ended September 30, 2011 we generated $0.2 million in revenue from our VEO lateral access and interbody fusion system, which was commercially launched in November 2011, compared to $0.5 million in the three months ended September 30, 2012. During both the three months ended September 30, 2011 and 2012 we generated $0.2 million, in revenues from sales of our posterior fixation systems. Sales of our Bi-Ostetic bone void filler decreased from $0.3 million in the three months ended September 30, 2011 to $0.2 million in the three months ended September 30, 2012, primarily due to the decrease in AxiaLIF cases. Revenue generated outside the United States decreased from $0.4 million in the three months ended September 30, 2011 to $0.3 million in the three months ended September 30, 2012. Effective January 1, 2012, we replaced our direct sales representatives in Europe with an independent sales agent, comprised of former employees of our direct sales organization. There were no initial stocking shipments to new distributors outside the United States in the three months ended September 30, 2011 compared to $85,000 in initial stocking shipments to new distributors in the three months ended September 30, 2012. In both the three months ended September 30, 2011 and 2012, 91% of our revenues were generated in the United States.

13

Cost of Revenue Cost of revenue decreased from $1.0 million in the three months ended September 30, 2011 to $0.8 million in the three months ended September 30, 2012. Gross margin decreased from 77.8% in the three months ended September 30, 2011 to 73.8% in the three months ended September 30, 2012. The decrease in gross margin was due to a higher percentage of sales being derived from ancillary and distributed products in 2012 as compared to 2011, which have a lower gross margin than our AxiaLIF products, increased depreciation expense on reusable kits, primarily due to building reusable kits as we launched the VEO product, increased inventory obsolescence reserves taken and royalty expense.

Research and Development Research and development expenses increased from $1.0 million in the three months ended September 30, 2011 to $1.4 million in the three months ended September 30, 2012. The increase in expenses of $0.4 million from 2011 to 2012 was primarily related to increased clinical trials expense of $0.2 million and an increase in personnel-related costs of $0.2 million as we increased our headcount in our regulatory and clinical functions.

Sales and Marketing Sales and marketing expenses decreased from $4.6 million in the three months ended September 30, 2011 to $4.5 million in the three months ended September 30, 2012. The decrease in expenses from 2011 to 2012 of $0.1 million was primarily due to lower personnel-related costs of $0.4 including lower commissions of $0.3 million as our revenues declined, partially offset by an increase in training expenses of $0.1 million to train surgeons on our new products and an increase to travel and entertainment expense of $0.1 million.

General and Administrative General and administrative expenses increased from $1.3 million in the three months ended September 30, 2011 to $2.3 million in the three months ended September 30, 2012. The increase in expenses from 2011 to 2012 of $1.0 million was primarily due to an increase in legal fee expense of $0.7 million, primarily related to the investigation being conducted by the Department of Health and Human Services, Office of Inspector General and a restructuring expense of $0.3 million for establishing a reserve related to underutilized office space in our Wilmington facility.

Other Income (Expense), Net Other income (expense), net, increased from $32,000 in expense in the three months ended September 30, 2011 to $114,000 in expense in the three months ended September 30, 2012. The change of $82,000 from 2011 to 2012 was primarily related to a loss on the disposal of fixed assets in the three months ended September 30, 2012 from the disposal of obsolete components of certain reusable instrument kits and a decrease in interest income earned on cash and cash equivalents.

14

Comparison of the Nine Months Ended September 30, 2011 and 2012

Revenue Revenue decreased from $15.2 million in the nine months ended September 30, 2011 to $10.4 million in the nine months ended September 30, 2012. Consistent with the third quarter comparison, the $4.8 million decrease in revenue from 2011 to 2012 was primarily a result of a lower number of AxiaLIF cases performed in 2012, which was due primarily to physician reimbursement limitations and insurance denials for lumbar fusion surgery due to medical necessity. Domestically, sales of our AxiaLIF 1L and AxiaLIF 1L+ products decreased from $7.4 million in the nine months ended September 30, 2011 to $4.3 million in the nine months ended September 30, 2012, and sales of our AxiaLIF 2L+ products decreased from $4.2 million in the nine months ended September 30, 2011 to $2.6 million in the nine months ended September 30, 2012. In the nine months ended September 30, 2012, average revenue per AxiaLIF case increased, primarily as a result of a price increase effective April 1, 2012, the release of new AxiaLIF products and penetration into existing cases by our other products. In the nine months ended September 30, 2011 and 2012, we recorded 1,041 and 579 domestic AxiaLIF cases, respectively, including 280 AxiaLIF 2L+ cases in the nine months ended September 30, 2011, and 174 AxiaLIF 2L+ cases in the nine months ended September 30, 2012. During the nine months ended September 30, 2011 and 2012, we generated $0.3 million and $1.2 million in revenue from our VEO lateral access and interbody fusion system, which was commercially launched in November 2011. For the nine months ended September 30, 2011 and 2012 we generated $1.0 million and $0.6 million, respectively, in revenues from sales of our posterior fixation systems. Sales of our Bi-Ostetic bone void filler decreased from $0.8 million in the nine months ended September 30, 2011 to $0.6 million in the nine months ended September 30, 2012, primarily due to the decrease in AxiaLIF cases. Revenue generated outside the United States decreased from $1.4 million in the nine months ended September 30, 2011 to $0.8 million in the nine months ended September 30, 2012. Effective January 1, 2012, we replaced our direct sales representatives in Europe with an independent sales agent, comprised of former employees of our direct sales organization. In the nine months ended September 30, 2011 and 2012, there were $47,000 and $110,000, respectively, in initial stocking shipments to new distributors outside the United States. In the nine months ended September 30, 2011 and 2012, 91% and 92%, respectively, of our revenues were generated in the United States.

Cost of Revenue Cost of revenue decreased from $3.5 million in the nine months ended September 30, 2011 to $2.7 million in the nine months ended September 30, 2012. Gross margin decreased from 76.8% in the nine months ended September 30, 2011 to 73.7% in the nine months ended September 30, 2012. The decrease in gross margin was due to a higher percentage of sales being derived from ancillary and distributed products in 2012 as compared to 2011, which have a lower gross margin than our AxiaLIF products, increased depreciation expense on reusable kits, primarily due to building reusable kits as we launched the VEO product, and royalty expense. These decreases in gross margin were partially offset by lower inventory obsolescence reserves taken in the current year.

Research and Development Research and development expenses increased from $3.8 million in the nine months ended September 30, 2011 to $3.9 million in the nine months ended September 30, 2012. The $0.1 million increase in expenses from 2011 to 2012 was primarily related to an increase in personnel-related expense of $0.2 million as we increased our headcount in regulatory and clinical functions and an increase in travel and entertainment expenses of $0.1 million, partially offset by a decrease in project and clinical study expense of $0.2 million.

15

Sales and Marketing Sales and marketing expenses decreased from $16.7 million in the nine months ended September 30, 2011 to $15.1 million in the nine months ended September 30, 2012. The decrease in expenses from 2011 to 2012 of $1.6 million was primarily due to lower personnel-related costs of $1.3 million as we reduced our direct sales headcount, lower commissions of $0.8 million as our revenues declined and decreased travel and entertainment expenses of $0.2 million related to the lower headcount, partially offset by an increase in consulting and training expenses of $0.7 million.

General and Administrative General and administrative expenses increased from $4.5 million in the nine months ended September 30, 2011 to $6.4 million in the nine months ended September 30, 2012. The increase in expenses from 2011 to 2012 of $1.9 million was primarily related to an increase in legal fee expense of $2.0 million, primarily related to the investigation being conducted by the Department of Health and Human Services, Office of Inspector General.

Other Income (Expense), Net Other income (expense), net, decreased from $7,000 in income in the nine months ended September 30, 2011 to expense of $146,000 in the nine months ended September 30, 2012. The change of $153,000 from 2011 to 2012 was primarily related to a loss on the disposal of fixed assets in the nine months ended September 30, 2012 from the disposal of obsolete components of certain reusable instrument kits and a decrease in interest income earned on cash and cash equivalents.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception in 2000, we have incurred significant losses and, as of September 30, 2012, we had an accumulated deficit of $126.8 million. We have not yet achieved profitability, and we cannot assure investors that we will achieve profitability with our existing capital resources. We expect to continue to fund research and development, sales and marketing and general and administrative expenses at similar to current levels or higher and, as a result, we will need to generate significant revenues to achieve profitability. Prior to our October 2007 initial public offering, our operations were funded primarily with the gross proceeds from the sale of preferred stock of $40.5 million. The net proceeds from our October 2007 initial public offering of $86.7 million and the net proceeds of our September 2011 stock offering of $18.2 million have funded our operations since then.

In May 2011, we filed a “universal shelf” Registration Statement on Form S-3 (Filing No. 333-174255)(the “Shelf Registration Statement”) with the Securities and Exchange Commission (“SEC”), which became effective on August 1, 2011. The Shelf Registration Statement allowed us to raise up to $50 million through the sale of debt securities, common stock, preferred stock, or warrants, or any combination thereof. On September 21, 2011, we entered into a purchase agreement with Piper Jaffray & Co. as the lead underwriter, to sell 6,200,000 shares of our common stock in a public offering. The shares were offered and sold pursuant to a prospectus supplement dated September 21, 2011 and an accompanying base prospectus dated August 1, 2011, in connection with a "takedown" offering pursuant to the Shelf Registration Statement. On September 26, 2011, the shares were sold to the public at a price of $3.25 per share. The net proceeds, after deducting underwriting discounts, commissions and offering expenses, were $18.2 million. As a result of the public offering of the shares, we are currently authorized to issue up to $29.85 million of our securities pursuant to the Shelf Registration Statement (which amount may be subject to increase in accordance with SEC rules). The timing and terms of any additional financing transactions pursuant to the Shelf Registration Statement, or otherwise, have not yet been determined. Any additional financing may not be available in amounts or on terms acceptable to us, if at all.

16

As of September 30, 2012, we did not have any outstanding debt financing arrangements, other than capital lease obligations, we had working capital of $30.5 million and our primary source of liquidity was $27.2 million in cash and cash equivalents. We currently invest our cash and cash equivalents primarily in money market treasury funds.

Cash, cash equivalents and short-term investments decreased from $44.8 million at December 31, 2011 to $27.2 million at September 30, 2012. The decrease of $17.6 million was primarily the result of net cash used in operating activities of $15.8 million and purchases of property and equipment of $1.8 million.

Cash Flows

Net Cash Used in Operating Activities. Net cash used in operating activities was $15.8 million in the nine months ended September 30, 2012. This amount was attributable primarily to the net loss after adjustment for non-cash items, such as depreciation, stock-based compensation expense, inventory, and bad debt reserves, and the loss on disposal of fixed assets, combined with changes in working capital requirements to support the market acceptance of our products.

Net Cash Provided by Investing Activities. Net cash provided by investing activities was $4.2 million in the nine months ended September 30, 2012. This amount reflected sales and maturities of short-term investments of $6.0 million, offset by the purchases of property and equipment of $1.8 million, primarily for reusable instrument kits used in the field and up-fitting our new training facility.

Net Cash Provided by Financing Activities. Net cash provided by financing activities in the nine months ended September 30, 2012 was $68,000, which represented proceeds from the issuance of shares of common stock under our employee stock purchase program and upon the exercise of stock options.

Operating Capital and Capital Expenditure Requirements

We believe that our existing cash and cash equivalents, together with cash received from sales of our products, will be sufficient to meet our anticipated cash needs for at least the next twelve months. We intend to spend substantial amounts on sales and marketing initiatives to support the ongoing commercialization of our products and on research and development activities, including product development, regulatory and compliance, clinical studies in support of our currently marketed products and future product offerings, and the enhancement and protection of our intellectual property. To the extent our available cash and cash equivalents are insufficient to satisfy our operating requirements, we will need to seek additional sources of funds, including selling additional equity, debt or other securities, or modify our current business plan.

Under the Shelf Registration Statement, we have the ability to issue debt securities, common stock, preferred stock, or warrants, or any combination thereof. We are currently authorized to issue up to $29.85 million of our securities pursuant to the Shelf Registration Statement (which amount may be subject to increase in accordance with SEC rules). The timing and terms of any additional financing transactions, whether pursuant to the Shelf Registration Statement or otherwise, have not yet been determined.

17

If we raise additional funds by issuing equity or convertible debt securities, our stockholders may experience dilution and the securities may contain terms that are preferential to the new investors as compared to the holders of our common stock. If we raise additional funds by issuing debt securities, the securities may have rights senior to those associated with our common stock and contain covenants that could restrict our operations, our ability to pay dividends, the amount of capital expenditures we can make, or our ability to incur additional debt. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. In addition, if we raise additional funds through collaboration and licensing arrangements with third parties, it may be necessary to relinquish some rights to our technologies or our products, or grant licenses on terms that are not favorable to us. If we are unable to raise adequate funds, we may have to delay, reduce the scope of or eliminate some or all of our planned product development and marketing efforts. Additionally, if we do not have, or are not able to obtain, sufficient funds, we may have to delay development or commercialization of our products or license to third parties the rights to commercialize products or technologies that we would otherwise seek to commercialize. We also may have to reduce marketing, customer support or other resources devoted to our products or cease operations.

In October 2011, we received a subpoena issued by the Department of Health and Human Services, Office of Inspector General, under the authority of the federal healthcare fraud and false claims statutes. We are cooperating with the government’s request and are in the process of responding to the subpoena. Although we cannot predict whether or when proceedings might be initiated by the federal government or when these matters may be resolved, it is not unusual for investigations such as these to continue for a considerable period of time. Responding to the subpoena will continue to require management’s attention and significant legal expense. Any negative findings could result in substantial financial penalties against us. To our knowledge, no proceedings have been initiated against the Company at this time. We are currently unable to predict what impact, if any, the outcome of this matter might have on our consolidated financial position, results of operations, or cash flows.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, revenue and expenses, and disclosures of contingent assets and liabilities at the date of the financial statements. On an on-going basis, we evaluate our estimates, including those related to revenue recognition, accounts receivable reserves, inventory reserves, accrued expenses, income tax valuations and stock-based compensation. We base our estimates on historical experience and various other assumptions that we believe to be reasonable, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not apparent from other sources. Actual results could differ from those estimates under different assumptions or conditions.

For a description of our critical accounting policies and estimates, please refer to the “Critical Accounting Policies and Estimates” section of the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section contained in our Annual Report on Form 10-K for the year ended December 31, 2011. There have been no material changes in any of our accounting policies since December 31, 2011.

18

New Accounting Standards

In May 2011, the FASB issued new authoritative guidance to provide a consistent definition of fair value and ensure that fair value measurements and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. This guidance changes certain fair value measurement principles and enhances the disclosure requirements for fair value measurements. This guidance was effective for interim and annual periods beginning after December 15, 2011 and is applied prospectively. We implemented this guidance in the first quarter of 2012 and it did not have a material impact on our financial statements.

In June 2011, the FASB issued guidance on the presentation of comprehensive income. This guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity and requires the presentation of other comprehensive income in a single continuous statement, or in two separate, but consecutive, statements. This guidance was effective for fiscal years and interim periods beginning after December 15, 2011. We implemented this guidance in the first quarter of 2012 and it did not have a material effect on our financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are filing this report as a “Smaller Reporting Company” and, as a result, are not required to provide disclosure pursuant to this Item 3 of Part I of Form 10-Q.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of September 30, 2012. We maintain disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2012, our principal executive officer and principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

19

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Reporting Status

Effective July 1, 2010, we became a “Smaller Reporting Company” under Rule 12b-2 of the Exchange Act and we continue to qualify as a “Smaller Reporting Company” for purposes of filing this report. Prior to that date, we were an “Accelerated Filer” under Rule 12b-2. This classification is based on the aggregate market value of our voting and non-voting stock held by non-affiliates as of the last trading day of our second fiscal quarter of any particular fiscal year.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are subject to legal proceedings and claims in the ordinary course of our business. These claims potentially cover a variety of allegations spanning our entire business. The following is a brief discussion of the most significant claims that have been brought against us in the operation of our business.

In October 2011, we received a subpoena issued by the Department of Health and Human Services, Office of Inspector General, under the authority of the federal healthcare fraud and false claims statutes. The subpoena seeks documents for the period January 1, 2008 through October 6, 2011. We are cooperating with the government’s request and are in the process of responding to the subpoena. We, along with our counsel, have met with representatives from the government several times during the past four months and continue to work toward a conclusion to this matter. We are unable to predict what action, if any, might be taken in the future by the Department of Health and Human Services, Office of Inspector General or other governmental authorities as a result of the matters related to this subpoena or what impact, if any, the outcome of these matters might have on our consolidated financial position, results of operations, or cash flows. No claims have been made against us at this time. Our liability, if any, resulting from this investigation cannot be estimated and as such, we have not recorded any liability within the condensed consolidated financial statements in relation to this matter.

In January 2012, we received notice that a class action lawsuit had been filed in the U.S. District Court Eastern District, North Carolina, on behalf of a class consisting of all persons other than the defendants who purchased our common stock between February 21, 2008 and October 17, 2011. We are in the process of responding to this lawsuit. We are unable to predict what impact, if any, the outcome of this matter might have on our consolidated financial position, results of operations, or cash flows.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

(b) Uses of Proceeds from Sale of Registered Securities

In May 2011, we filed the Shelf Registration Statement with the SEC, which became effective on August 1, 2011. The Shelf Registration Statement allowed us to raise up to $50 million through the sale of debt securities, common stock, preferred stock, or warrants, or any combination thereof.

20

On September 21, 2011, we entered into a purchase agreement with Piper Jaffray & Co., as the lead underwriter, to sell 6,200,000 shares of our common stock in a public offering. The shares were offered and sold pursuant to a prospectus supplement dated September 21, 2011 and an accompanying base prospectus dated August 1, 2011, in connection with a "takedown" offering pursuant to the Shelf Registration Statement. On September 26, 2011, the shares were sold to the public at a price of $3.25 per share. The net proceeds, after deducting underwriting discounts, commissions and offering expenses, were $18.2 million. As a result of the public offering of the shares, we are currently authorized to issue up to $29.85 million of our securities pursuant to the Shelf Registration Statement (which amount may be subject to increase in accordance with SEC rules). The timing and terms of any additional financing transactions pursuant to the Shelf Registration Statement or otherwise, have not yet been determined.

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

4. Net Loss Per Common Share

Basic net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding. Diluted net loss available to common stockholders per common share is computed by dividing net loss by the weighted average number of common shares and dilutive potential common share equivalents then outstanding. The Company’s potential dilutive common shares, which consist of shares issuable upon the exercise of stock options, have not been included in the computation of diluted net loss per share for all periods as the result would be anti-dilutive.

The following table sets forth the potential shares of common stock that are not included in the calculation of diluted net loss per share as the result would be anti-dilutive as of the end of each period presented:

Nature of Operations [Text Block]

1. Description of Business

TranS1 Inc., a Delaware corporation (the “Company”), was incorporated in May 2000 and is headquartered in Wilmington, North Carolina. The Company is a medical device company focused on designing, developing and marketing products to treat degenerative conditions of the spine affecting the lower lumbar region. The Company operates in one business segment. The Company currently markets the AxiaLIF® family of products for single and two level lumbar fusion, the VEO^TM lateral access and interbody fusion system, the Vectre™ lumbar posterior fixation system and Bi-Ostetic^TM bone void filler, a biologics product. All of the Company’s AxiaLIF products are delivered using its pre-sacral approach. The Company also markets products that may be used with its surgical approach, including bowel retractors, a bone graft harvesting system and additional discectomy tools. The AxiaLIF 1L product was commercially released in January 2005. The AxiaLIF 2L™ product was commercially released in Europe in the fourth quarter of 2006 and in the United States in the second quarter of 2008. The AxiaLIF 2L product was discontinued in 2010 after the Company launched its AxiaLIF 2L+™ product in July 2010. The Company commercially launched its next generation Vectre facet screw system in April 2010. In the first quarter of 2010, the Company entered into an agreement to distribute Bi-Ostetic bone void filler, a biologics product. The Company commercially launched its AxiaLIF 1L+ product in September 2011. The Company commercially launched its VEO lateral access and interbody fusion system in November 2011 in the United States and in July 2012 in the European Union. The Company sells its products through a direct sales force, independent sales agents and independent distributors.

The Company has forty-five issued United States patents, fourteen pending patent applications or provisional patent applications in the United States, eight issued European patents, seven issued Japanese patents, and seven foreign patent application families as counterparts of U.S. cases. The issued and pending patents cover, among other things, (i) the Company’s method for performing trans-sacral procedures in the spine, including diagnostic or therapeutic procedures, and trans-sacral introduction of instrumentation or implants, (ii) apparatus for conducting these procedures including access, disc preparation and implantation including the current TranS1 instruments individually and in kit form, (iii) implants for fusion and motion preservation in the spine, and (iv) a lateral access and interbody fusion system.

The Company owns eight trademark registrations in the United States, nine trademark registrations in the European Union and two registered trademarks in Canada. The Company also owns two pending trademark applications in the United States, four pending trademark applications in China and one pending trademark application in the European Union.

On September 26, 2011, the Company completed a public offering of 6,200,000 shares of its common stock at an offering price of $3.25 per share. The offering resulted in aggregate proceeds to the Company of approximately $18.2 million, net of underwriting discounts, commissions and offering expenses, and has been included in stockholders' equity as common stock and additional paid-in capital. At September 30, 2012 and December 31, 2011, there were 27,274,823 and 27,244,059 shares of common stock issued and outstanding, respectively, and there were no shares of preferred stock issued and outstanding.

The Company is subject to a number of risks similar to other similarly-sized companies in the medical device industry. These risks include, without limitation, acceptance and continued use of the Company’s products by surgeons, the lack of clinical data about the efficacy of these products, uncertainty of reimbursement from third-party payors, cost pressures in the healthcare industry, competitive pressures from substitute products and larger companies, the historical lack of profitability, the dependence on key employees, regulatory approval and market acceptance for new products, compliance with complex and evolving healthcare laws and regulations, uncertainty surrounding the outcome of the matters relating to the subpoena issued to the Company by the Department of Health and Human Services, Office of Inspector General, the reliance on a limited number of suppliers to provide these products, changes in economic conditions, the ability to effectively manage a sales force to meet the Company’s objectives and the ability to conduct successful clinical studies.

Accounting Policies [Abstract]

Basis of Presentation and Significant Accounting Policies [Text Block]

2. Basis of presentation

The Company has prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC. The consolidated financial statements are unaudited and should be read in conjunction with the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2011. The accompanying unaudited interim consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of the Company’s management, necessary for a fair statement of the Company’s consolidated financial position, results of operations and cash flows for the periods presented. These principles require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The principal estimates relate to accounts receivable reserves, inventory reserves, stock-based compensation, accrued expenses and income tax valuations. Actual results could differ from those estimates. The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. All intercompany accounts and transactions have been eliminated in consolidation.

Impact of Recently Issued Accounting Standards

In May 2011, the Financial Accounting Standard Board (“FASB”)issued new authoritative guidance to provide a consistent definition of fair value and ensure that fair value measurements and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. This guidance changes certain fair value measurement principles and enhances the disclosure requirements for fair value measurements. This guidance was effective for interim and annual periods beginning after December 15, 2011 and is applied prospectively. The Company implemented this guidance in the first quarter of 2012 and it did not have a material impact on its financial statements.

In June 2011, the FASB issued guidance on the presentation of comprehensive income. This guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity and requires the presentation of other comprehensive income in a single continuous statement, or in two separate, but consecutive, statements.This guidance was effective for fiscal years and interim periods beginning after December 15, 2011. The Company implemented this guidance in the first quarter of 2012 and it did not have a material effect on its financial statements.

In October 2011, the Company received a subpoena issued by the Department of Health and Human Services, Office of Inspector General, under the authority of the federal healthcare fraud and false claims statutes. The subpoena seeks documents for the period January 1, 2008 through October 6, 2011. The Company is cooperating with the government’s request and is in the process of responding to the subpoena. The Company and its counsel have met with representatives from the government several times during the past four months and continue to work toward a conclusion to this matter. The Company is unable to predict what action, if any, might be taken in the future by the Department of Health and Human Services, Office of Inspector General or other governmental authorities as a result of the matters related to this subpoena or what impact, if any, the outcome of these matters might have on the Company’s consolidated financial position, results of operations, or cash flows. No claims have been made against the Company at this time. The Company’s liability, if any, resulting from this investigation cannot be estimated and as such, the Company has not recorded any liability within the condensed consolidated financial statements in relation to this matter.

In January 2012, the Company received notice that a class action lawsuit had been filed in the U.S. District Court Eastern District, North Carolina, on behalf of a class consisting of all persons other than the defendants who purchased the Company’s common stock between February 21, 2008 and October 17, 2011. The Company is in the process of responding to this lawsuit. The Company is unable to predict what impact, if any, the outcome of this matter might have on the Company’s consolidated financial position, results of operations, or cash flows.

5. Cash, Cash Equivalents and Investments

The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents include money market treasury funds. Short-term investments consist of U.S. agency backed debt instruments.

At September 30, 2012, the Company held certain assets that are required to be measured at fair value on a recurring basis. These assets include available for sale securities classified as cash equivalents. Accounting Standards Codification 820-10 requires the valuation of investments using a three-tiered approach, which requires that fair value measurements be classified and disclosed in one of three tiers. These tiers are: Level 1, defined as quoted prices in active markets for identical assets or liabilities; Level 2, defined as valuations based on observable inputs other than those included in Level 1, such as quoted prices for similar assets and liabilities in active markets, or other inputs that are observable or can be corroborated by observable input data; and Level 3, defined as valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants.

Cash and available for sale securities classified as Level 1 assets were:

	September 30,		December 31,
	2012		2011

Cash and cash equivalents	$	27,233	$	38,340
Short-term investments		0		6,027
Total cash and available for sale securities	$	27,233	$	44,367

The Company had no Level 2 or Level 3 assets or liabilities at September 30, 2012 or December 31, 2011.
