Basis of Presentation

These unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”), and include all assets and liabilities of the Company and its wholly-owned subsidiary, US Spine. All material intercompany transactions and balances have been eliminated in consolidation. SEC rules and regulations allow the omission of certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States, so long as the statements are not misleading. In the opinion of management, these financial statements and accompanying notes contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position and results of operations for the periods presented herein. These condensed consolidated financial statements should be read in conjunction with the consolidated audited financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016, filed with the SEC on September 20, 2017. The results of operations for the six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017. The Company’s significant accounting policies are set forth in Note 1 to the consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2016.

Liquidity and Capital Resources

The condensed consolidated financial statements have been prepared assuming the Company will continue to operate as a going concern, which contemplates the realization of assets and settlement of liabilities in the normal course of business, and does not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to its ability to continue as a going concern within one year from the date of issuance of these condensed consolidated financial statements.

For the six months ended June 30, 2017 and 2016, the Company incurred net losses of $4.3 million and $8.5 million, respectively, and used cash in operations of $3.4 million and $2.4 million, respectively. The Company had an accumulated deficit of $217 million and $213 million as of June 30, 2017 and December 31, 2016, respectively. To date, the Company’s operations have been principally financed by proceeds received from the issuance of preferred and common stock, convertible debt and bank debt and, to a lesser extent, cash generated from product sales. It is anticipated that the Company will continue to generate operating losses and use cash in operating activities. The Company’s continuation as a going concern is dependent upon its ability to increase sales, implement cost saving measures, maintain compliance with debt covenants and/or raise additional funds through the capital markets. Whether and when the Company can attain profitability and positive cash flows from operating activities or obtain additional financing is uncertain.

In 2016, the Company implemented certain cost saving measures, including workforce and office space reductions, and will continue to evaluate additional cost savings alternatives during 2017. These additional cost savings measures may include additional workforce and research and development reductions, as well as cuts to certain other operating expenses. In addition to these costs saving measures, an experienced and highly successful leader for the Sales and Marketing team was recruited and hired. This individual has subsequently hired additional experienced personnel in Sales and Marketing. The Company is actively generating additional scientific and clinical data to have it published in leading industry publications. The unique features of the Company’s silicon nitride material are not well known, and publication of such data would help sales efforts as the Company approaches new prospects. The Company is also making additional changes to the sales strategy, including a focus on revenue growth of silicon nitride lateral lumbar implants and the newly developed pedicle screw system (known as Taurus).

As discussed further in Note 7, in June 2014 the Company entered into a term loan with Hercules Technology Growth Capital, Inc. (“Hercules Technology”), as administrative and collateral agent for the lenders thereunder and as lender, and Hercules Technology III, LP, (“HT III” and, together with Hercules Technology, “Hercules”) as lender (the “Hercules Term Loan”). The Hercules Term Loan has a liquidity covenant that requires the Company to maintain a cash balance of not less than $2.5 million as of June 30, 2017. As of June 30, 2017, the Company’s cash balance was approximately $3.5 million. The Company believes it will be in position to maintain compliance with the liquidity covenant related to the Hercules Term Loan at least through October 2017, as once the Hercules Term Loan principal balance is reduced below $2.5 million the Company is only required to maintain a cash balance equal to the outstanding balance of the Hercules Term Loan from that point forward. The Company has common stock that is publicly traded and has been able to successfully raise capital when needed since the date of the Company’s initial public offering. The Company is engaged in discussions with investment and banking firms to examine financing alternatives, including options to encourage the exercise of outstanding warrants and other lending alternatives. On July 28, 2017, the Company entered into a $2.5 million term loan that will assist the Company in its cash needs through November 2017 (see Note 11).

If the Company is unable to access additional funds prior to becoming non-compliant with the financial and liquidity covenants related to the Hercules Term Loan, the outstanding balance of the Hercules Term Loan would become immediately due and payable at the option of the lender. Although the Company is seeking to obtain additional equity and/or debt financing, such funding is not assured and may not be available to the Company on favorable or acceptable terms, and may involve significant restrictive covenants. Any additional equity financing is also not assured and, if available to the Company, will most likely be dilutive to its current stockholders. If the Company is not able to obtain additional debt or equity financing on a timely basis, the impact on the Company will be material and adverse.

New Accounting Pronouncement, Not Yet Adopted

In January 2017, the FASB issued ASU 2017-04 Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in this guidance eliminate the requirement to calculate the implied fair value of goodwill used to measure goodwill impairment charge (Step 2). As a result, an impairment charge will equal the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the amount of goodwill allocated to the reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendment should be applied on a prospective basis. The guidance is effective for goodwill impairment tests in fiscal years beginning after December 15, 2021. Early adoption is permitted for goodwill impairment tests performed after January 1, 2017. The impact of this guidance for the Company will depend on the outcomes of future goodwill impairment tests.

In August 2016, the Financial Accounting Standards Board (“FASB”) updated accounting guidance on the following eight specific cash flow classification issues: (1) debt prepayment or debt extinguishment costs; (2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (3) contingent consideration payments made after a business combination; (4) proceeds from the settlement of insurance claims; (5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (6) distributions received from equity method investees; (7) beneficial interests in securitization transactions; and (8) separately identifiable cash flows and application of the predominance principle. Under existing U.S. GAAP, there is no specific guidance on the eight cash flow classification issues aforementioned. These updates are effective for the Company for its annual period beginning January 1, 2019, and interim periods therein, with early adoption permitted. The guidance in this standard is not expected to have a material impact on the financial statements of the Company.

In March 2016 the FASB updated the accounting guidance related to stock compensation. This update simplifies the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as the well as classification in the statement of cash flows. The standard is effective for the Company for its annual period beginning January 1, 2018. The guidance in this standard is not expected to have a material impact on the financial statements of the Company.

In February 2016, the FASB updated the accounting guidance related to leases as part of a joint project with the International Accounting Standards Board (“IASB”) to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, a lessee will be required to recognize assets and liabilities for capital and operating leases with lease terms of more than 12 months. Additionally, this update will require disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. The standard is effective for the Company for its annual period beginning January 1, 2020, and interim periods therein, with early adoption permitted. The Company is currently evaluating the potential impact this new standard may have on its financial statements, but believes the most significant change will relate to building leases.

In May 2014, in addition to several amendments issued during 2016, the FASB updated the accounting guidance related to revenue from contracts with customers, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle is that a company should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. The standard defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. The standard is effective for the Company for its annual period beginning January 1, 2019, and interim periods therein, and shall be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is in the preliminary stages of evaluating the impact that the new standard will have on its financial statements.

The Company has reviewed all other recently issued, but not yet adopted, accounting standards, in order to determine their effects, if any, on its results of operations, financial position or cash flows. Based on that review, the Company believes that no other pronouncements will have a significant effect on its financial statements.
