1. Organization and Summary of Significant Accounting Policies

Organization

SINTX Technologies, Inc. (“SINTX” or “the Company”) (previously known as Amedica Corporation) was incorporated in the state of Delaware on December 10, 1996. SINTX is a commercial-stage biomaterial company focused on using its silicon nitride technology platform to develop, manufacture, and commercialize a broad range of medical devices. The Company believes it is the first and only manufacturer to use silicon nitride in medical applications. The Company acquired US Spine, Inc. (“US Spine”), a Delaware spinal products corporation with operations in Florida, on September 20, 2010. The Company’s products are primarily sold in the United States.

As further explained in Note 12, On October 1, 2018, the Company completed the sale of its retail spine business to CTL Medical, a Dallas, Texas-based privately held medical device manufacturer. As a result of the sale, CTL Medical is now the exclusive owner of SINTX’s portfolio of metal and silicon nitride spine products, which are presently sold under the brand names of Taurus, Preference, and Valeo, with access to future silicon nitride spine technologies. Manufacturing, R&D, and all intellectual property related to the core, non-spine, biomaterial technology of silicon nitride remains with the Company. The Company will serve as CTL’s exclusive OEM provider of silicon nitride products.

On October 30, 2018, the Company amended its Certificate of Incorporation with the State of Delaware to change its corporate name to SINTX Technologies, Inc. in order to better reflect its focus on silicon nitride science and technologies and pipeline of silicon nitride-based products in various biomedical applications. The Company also changed its trading symbol on the NASDAQ Capital Market to “SINT”. The Company also changed the name of its wholly owned subsidiary US Spine, Inc. to “ST Sub, Inc.”

The previous name, Amedica, has transferred to CTL Medical, which is now CTL-Amedica. The Company’s new corporate brand reflects both the Company’s core competence in the science and production of silicon nitride ceramics, as well as encouraging prospects for the future, as an OEM supplier of spine implants to CTL-Amedica, and several opportunities outside of spine. As SINTX Technologies Inc., the Company will focus on developing silicon nitride in terms of product design, and future biomaterial formulations, for a variety of OEM customers.

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, ST Sub, Inc. 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, 2018, filed with the SEC on March 8, 2019. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results to be expected for the year ending December 31, 2019. 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, 2018. 

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the periods then ended. Actual results could differ from those estimates. The most significant estimates relate to inventory, stock-based compensation, long-lived and intangible assets and the liability for preferred stock and common stock warrants.

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 do 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, 2019 and 2018, the Company incurred net losses from continuing operations of approximately $1.6 million and $3.5 million, respectively, and used cash in continuing operations of approximately $1.7 million and $2.3 million, respectively. The Company had an accumulated deficit of approximately $231 million and $229 million as of March 31, 2019 and December 31, 2018, 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 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.

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 the Company believes that 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 March 2018, the Company closed on gross proceeds of $1.4 million, before payment of placement agent fees and costs on a warrant reprice and exercise transaction. Additionally, on May 14, 2018, the Company closed on a public offering of units, consisting of convertible preferred stock and warrants, for gross proceeds of $15 million, which excludes underwriting discounts and commissions and offering expenses payable by the Company. The Company is engaged in discussions with investment and banking firms to examine financing alternatives, including options for a public offering of the Company’s preferred or common stock. On October 1, 2018, the Company sold the retail spine business. This sale will provide cash flows totaling $2.5 million over the next eighteen months and $3.5 million for the following eighteen months. The buyer also assumed the Company’s $2.5 million related party note payable.

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.

These uncertainties create 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.

Significant Accounting Policies

Except as explained below, no material changes were made to the Company’s significant accounting policies as described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Accounting Pronouncements Adopted During the Quarter Ended March 31, 2019

In August 2016, the 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 prior U.S. GAAP, there was no specific guidance on the eight cash flow classification issues aforementioned. The Company adopted the new guidance effective January 1, 2019. The guidance in this standard did not have a material impact on the financial statements of the Company upon adoption.

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. The Company adopted the new guidance effective January 1, 2019 (see Note 13), using the modified retrospective approach. Under the new guidance, the Company was required to record an additional operating lease right-of-use asset totaling approximately $0.659 million and liability totaling approximately $0.946 million (with $0.659 million incremental to adoption of the new guidance) on the date of adoption. The standard did not materially impact the consolidated net loss and had no impact on cash flows.

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 Company adopted the new guidance effective January 1, 2019. The core principle of the new guidance 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 are often required within the revenue recognition process than were required under prior U.S. GAAP. The Company has one primary customer (see Note 12) and related contract that has one performance obligation to which revenue is allocated. Revenue under this contract is recognized when the product is shipped to the customer. The Company generally bills its customer upon shipment of the product and invoices are generally due within 30 days. The Company does provide certain rights of return, which historically have not been significant. The Company does not anticipate incurring significant incremental costs to obtain contracts with future customers. The guidance in this standard did not have a material impact on the financial statements of the Company upon adoption.

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.
