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.

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, 2023, filed with the SEC on March 29, 2023. The results of operations for the three months ended March 31, 2024, are not necessarily indicative of the results to be expected for the year ending December 31, 2024. 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, 2023.

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, 2024, and 2023, the Company incurred a net loss of $0.9 million and $0.3 million, respectively, and used cash in operating activities of $2.7 million and $4.9 million, respectively. The Company had an accumulated deficit of $271.6 million and $270.7 million as of March 31, 2024, and December 31, 2023, 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 advanced ceramic materials 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 also acquired equipment and certain proprietary know-how for the purpose of developing, manufacturing and commercializing armored plates made from boron carbide and a composite of boron carbide and silicon carbide for military, law enforcement and other civilian uses.

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 25, 2021, the Company entered into an Equity Distribution Agreement (as amended, 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 million through Maxim, as agent. On October 12, 2023, the Company entered into an amendment to the Distribution Agreement, pursuant to which the expiration date of the Distribution Agreement was extended to 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, 2025. No other changes were made to the terms of the Distribution Agreement. The Company currently has registered up to $1.1 million for sale under the Distribution Agreement, pursuant to the Registration Statement on Form S-3 (File No. 333-274951). As of March 31, 2024, the Company had $0.07 million available for sale under the Distribution Agreement. As of March 31, 2024, there have been 2,471,949 shares of common stock sold under the 2021 Distribution Agreement for gross proceeds of $1.0 million. The Company is subject to General Instruction I.B.6 of Form S-3 which limits the amounts that we may sell under the registration statement over a 12-month period to an amount equal to or less than one-third of our public float. The shares of the Company’s common stock to be sold under the Distribution Agreement will be sold and issued pursuant to the Form S-3, as amended, which was previously declared effective by the Securities and Exchange Commission, and the related prospectus and one or more prospectus supplements.

On February 10, 2023, the Company closed on a public offering of 2,150,000 units, with each unit consisting of one share of common stock, or one pre-funded warrant to purchase one share of its common stock, one Class C Warrant to purchase one share of common stock, and one half of one Class D Warrant with each whole Class D Warrant entitling the holder to purchase one share of common stock. Gross proceeds, before deducting offering expenses, totaled approximately $12.0 million. Of the $12.0 million of gross proceeds, approximately $5.4 million were allocated to common stock and prefunded warrants ($4.8 million net of offering costs) and approximately $6.7 million were allocated to derivative liabilities (with approximately $0.7 million of cash offering costs and $0.1 million of agent warrant offering costs recorded as derivative expense).

On February 2, 2024, the Company closed on a public offering of 16,000,000 units, with each unit consisting of one share of its common stock, or one pre-funded warrant to purchase one share of its common stock, one Class E Warrant with each warrant to purchase one share of common stock, and one Class F Warrant with each warrant to purchase one share of common stock. Each unit was sold at a public offering price of $0.25 resulting in gross proceeds to the Company of $4 million before deducting offering fees and expenses. The Class E and Class F Warrants in the units will be immediately exercisable at a price of $0.25 per share. The Class E Warrants will expire five years from the date of issuance and the Class F Warrants will expire eighteen months from the date of issuance. Of the $4.0 million of gross proceeds, approximately $0.6 million were allocated to common stock and prefunded warrants ($0.5 million net of offering costs) and approximately $3.4 million were allocated to derivative liabilities (with approximately $0.5 million of cash offering costs and $0.1 million of agent warrant offering costs recorded as derivative expense).

On March 26, 2024, the Company closed on a public offering 28,400,000 shares of the Company’s common stock, (the “Offering”). Each Share was sold at a public offering price of $0.047. The aggregate proceeds to the Company from the Offering were approximately $1.3 million before deducting placement agent fees and other estimated offering expenses payable by the Company.

If the Company seeks 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. These uncertainties raise substantial doubt about our ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

New Accounting Pronouncements Not Yet Adopted

On December 14, 2023, the Financial Accounting Standards Board issued Accounting Standards Update, No. 2023-09 “Improvements to Income Tax Disclosures.” (“ASU 2023-09”). ASU 2023-09 enhances the detail that a business is required to disclose within its income tax footnote, including, but not limited to, a breakout of the rate reconciliation into more specific categories, such as state and local income tax, and foreign taxes. Additionally, a business must break out specific jurisdictions that encompass greater than or equal to 5% of their state and local, and foreign jurisdictions. The Company will adopt ASU 2023-09 on January 1, 2025. The adoption of this Standard is not expected to have a significant impact on the Company’s 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.
