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. In May 2020, the Company dissolved its wholly owned subsidiary ST Sub, Inc. At the time of dissolution, the subsidiary had no assets, liabilities, equity, or operations. The financial statements after May 8, 2020, are not consolidated.

SEC rules and regulations allow the omission of certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) 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, 2020, filed with the SEC on March 22, 2021. The results of operations for the three months ended March 31, 2021, are not necessarily indicative of the results to be expected for the year ending December 31, 2021. 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, 2020.

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 three months ended March 31, 2021 and 2020, the Company incurred a net loss of $2.6  million and generated a net income of $1.2  million, respectively, and used cash in operations of $3.0  million and $3.4 million, respectively. The Company had an accumulated deficit of $243.7 million and $241.1 million as of March 31, 2021 and December 31, 2020, respectively. To date, the Company’s operations have been principally financed from proceeds from the issuance of preferred and common stock 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 operations. The Company’s continuation as a going concern is dependent upon its ability to increase sales, and/or raise additional funds through the capital markets. Whether and when the Company can attain profitability and positive cash flows from operations or obtain additional financing is uncertain.

The Company is actively generating additional scientific and clinical data to have it published in leading industry publications. The unique features of our silicon nitride material are not well known, and we believe the 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 by expanding the use of silicon nitride in other areas outside of spinal fusion applications.

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 in February 2014. On February 6, 2020, the Company closed on a rights offering to its stockholders of units, consisting of convertible preferred stock and warrants, for gross proceeds of $9.4 million, which excludes underwriting discounts and commissions and offering expenses payable by the Company of approximately $1.2 million. Additionally, during the period of June 2020 through August 2020, the Company closed four registered direct offerings of shares of its common stock, priced at-the-market under Nasdaq rules, resulting in the issuance of a total of 11,015,000 shares of its common stock for gross proceeds of approximately $20.9 million, before considering issuance costs of approximately $1.6 million (see Note 8).

During the year ended December 31, 2019, the Company entered into an at-the-market (2019 ATM) equity distribution agreement under which the Company could sell, from time to time, shares of common stock having an aggregate offering price of up to $2.5 million. During the year ended December 31, 2020, the Company sold 354,381 shares of common stock under the ATM, raising approximately $0.8 million before deducting fees to the placement agent and other offering expenses of approximately $0.1 million. As of March 31, 2021, no funding capacity is available under the ATM. (see Note 8). 

On February 25, 2021, the Company entered into an Equity Distribution Agreement (the “2021 Distribution Agreement”) with Maxim Group LLC (“Maxim”), pursuant to which the Company may sell from time to time, shares of the Company’s common stock having an aggregate offering price of up to $15.0 million through Maxim, as agent. As of March 31, 2021, there have been no sales of shares of common stock under the 2021 Distribution Agreement.

Subject to the terms and conditions of the 2021 Distribution Agreement, Maxim will use its commercially reasonable efforts to sell the Shares from time to time, based on our instructions. Under the 2021 Distribution Agreement, Maxim may sell the Shares by any method permitted by law deemed to be an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act of 1933, as amended (the “Securities Act”), including, without limitation, sales made directly on the Nasdaq Capital Market. We have no obligation to sell any shares under the ATM and may at any time suspend offers under the 2021 Distribution Agreement. The Offering will terminate upon the earlier of (i) the sale of shares having an aggregate offering price of $15.0 million, (ii) the termination by either Maxim or the Company upon the provision of fifteen (15) days written notice, or (iii) February 25, 2022. Under the terms of the 2021 Distribution Agreement, Maxim will be entitled to a transaction fee at a fixed rate of 2.0% of the gross sales price of Shares sold under the 2021 Distribution Agreement. The Company will also reimburse Maxim for certain expenses incurred in connection with the 2021 Distribution Agreement and agreed to provide indemnification and contribution to Maxim with respect to certain liabilities under the Securities Act and the Securities Exchange Act of 1934, as amended. As of March 31, 2021 there have been no sales of shares of common stock under the 2021 Distribution Agreement.

On October 1, 2018, the Company sold the retail spine business to CTL Medical. The sale included a $6.0 million noninterest bearing note receivable payable over a 36-month term. The 36-month term of the note receivable requires 18 payments of $138,889 followed by 18 payments of $194,444, with maturing of the note receivable to occur October 1, 2021. The Company expects cash flows of approximately $1.4  million for the remaining seven months of the term of the note.

Management has concluded existing capital resources will be sufficient to fund operations for at least the next 12 months, or through May 2022.

New Accounting Pronouncements Not Yet Adopted

The Company has reviewed all 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.
