SINTX TECHNOLOGIES, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Organization and Summary of Significant Accounting Policies

The condensed consolidated financial statements include the accounts of SINTX Technologies, Inc. (“SINTX”) and its wholly-owned subsidiaries, SINTX Armor, Inc. (“SINTX Armor”) and Technology Assessment and Transfer, Inc. (TA&T), which are collectively referred to as “we” or “the Company”. SINTX is an advanced ceramics company formed in December 1996, focused on providing solutions in a variety of diverse fields, including biomedical, technical, and antipathogenic applications. SINTX is a company that has grown over time from focusing on the research and development of silicon nitride for use in human interbody implants to becoming an advanced ceramics company engaged in many different fields. The core strength of the Company is the manufacturing, research, and development of advanced ceramics for external partners. The Company presently manufactures ceramic powders and components in its Salt Lake City and Maryland facilities. The SINTX Salt Lake City facility is FDA and ANVISA registered, ISO 13485:2016 certified, and ASD9100D certified. The Company’s products are primarily sold in the United States.

The Company is focused on building revenue generating opportunities in three business industries - antipathogenic, technical (including armor), and biomedical – thereby connecting with current and new customers, partners and manufacturers to help realize the goal of leveraging expertise in high-tech ceramics to create new, innovative opportunities across these sectors. We expect our continued investment in research and development to provide additional revenue opportunities.

The Company’s initial focus was the development and commercialization of products made from silicon nitride for use in spinal fusion and hip and knee replacement applications. SINTX believes it is the first and only manufacturer to use silicon nitride in medical applications primarily focused on spine fusion therapies. Since then, we have developed other applications for our silicon nitride technology as well as utilized our expertise in the use of ceramic materials in other applications. In July 2021, the Company acquired the equipment and obtained certain proprietary know-how rights with which it intends to develop, manufacture, and commercialize protective armor from boron carbide and a composite material of silicon carbide and boron carbide for military, law enforcement and civilian uses. The protective armor operations are housed in SINTX Armor. In June 2022, the Company acquired TA&T, a nearly 40-year-old business with a mission to transition advanced materials and process technologies from a laboratory environment to commercial products and services.

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 became the exclusive owner of the Company’s portfolio of metal and silicon nitride spine products, as well as access to future silicon nitride spine technologies developed by the Company. The Company’s name, Amedica, was also transferred to CTL Medical, which is now CTL Amedica. The Company serves as CTL’s exclusive OEM provider of silicon nitride products. Manufacturing, R&D, and all intellectual property related to the core, non-spine, biomaterial technology including silicon nitride remains with the Company.

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. The Company also changed its trading symbol on the NASDAQ Capital Market to “SINT”.

The Company’s new corporate brand reflects both the Company’s core competence in the science and production of silicon nitride ceramics and other ceramics, as well as encouraging prospects for the future, as an OEM supplier of spine implants to CTL Amedica, and multiple opportunities outside of spine.

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 27, 2024. The results of operations for the six months ended June 30, 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.

Reverse Stock Split

On May 28, 2024, the Company effected a 1 for 200 reverse stock split of the Company’s common stock. The par value and the authorized shares of the common and preferred stock were not adjusted as a result of the reverse stock split. All common stock shares, equivalents, and per-share amounts for all periods presented in these consolidated financial statements have been adjusted retroactively to reflect the reverse stock split.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with 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 at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates. As of June 30, 2024, the most significant estimate relates to derivative liabilities relating to 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 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, 2024, and 2023, the Company incurred a net loss of $3.1 million and $2.7 million, respectively, and used cash in operating activities of $4.9 million and $8.1 million, respectively. The Company had an accumulated deficit of $273.8 million and $270.7 million as of June 30, 2024, and December 31, 2023, respectively. We will require substantial future capital in order to continue to continue operating our business, conduct the research and development and regulatory clearance and approval activities necessary to bring our products to market, and to establish effective marketing and sales capabilities. Our existing capital resources are not sufficient to enable us to fund the completion of the development and commercialization of all of our product candidates.

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.

We are actively seeking opportunities to raise additional capital. However, there can be no guarantee that we will be able to obtain such financing on terms favorable to us or at all.

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 and moving into other advanced ceramic materials outside of silicon nitride. 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.

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 $3.1 million for sale under the Distribution Agreement, pursuant to the Registration Statement on Form S-3 (File No. 333-274951). As of June 30, 2024, the Company had $0.07 million available for sale under the Distribution Agreement. On July 11, 2024, the Company filed a Prospectus Supplement with the SEC increasing the amount available for sale under the Distribution Agreement to $3.1 million. As of June 30, 2024, there have been 12,360 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 10,750 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 80,000 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 $50.00 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 $50.00 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 142,000 shares of the Company’s common stock, (the “Offering”). Each Share was sold at a public offering price of $9.40. 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.

On April 5, 2024, the Company closed on a public offering 358,000 shares of the Company’s common stock, (the “Offering”). Each Share was sold at a public offering price of $4.20. The aggregate proceeds to the Company from the Offering were approximately $1.5 million before deducting placement agent fees and other 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. Thecondensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

Grant and Contract Revenue

Revenues from grants, contracts, and awards provided by governmental agencies are recorded based upon the terms of the specific agreements, which generally provide that revenue is earned when the allowable costs specified in the applicable agreement have been incurred or a milestone has been met. Cash received from federal grants, contracts, and awards can be subject to audit by the grantor and, if the examination results in a disallowance of any expenditure, repayment could be required.

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.

2. Basic and Diluted Net Income (Loss) per Common Share

Basic net income (loss) per share is calculated by dividing the net income (loss) by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period that are determined to be dilutive. Common stock equivalents are primarily comprised of preferred stock and warrants for the purchase of common stock. The Company had potentially dilutive securities that were not included in the fully diluted loss per share calculation because they would have been antidilutive totaling approximately 79 thousand and 6 thousand as of June 30, 2024, and 2023, respectively.

Below are basic and diluted loss per share data for the three months ended June 30, 2024, which are in thousands except for share and per share data:

Below are basic and diluted loss per share data for the six months ended June 30, 2024, which are in thousands except for share and per share data:

3. Inventories

Inventories consisted of the following (in thousands):

As of June 30, 2024, inventories totaling approximately $0.4 million and $0.6 million were classified as current and long-term, respectively.

4. Fair Value Measurements

Financial Instruments Measured and Recorded at Fair Value on a Recurring Basis

The Company has issued certain warrants to purchase shares of common stock, which are considered derivative liabilities because they have registration rights which could require a cash settlement and are re-measured to fair value at each reporting period in accordance with accounting guidance. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:

The Company classifies assets and liabilities measured at fair value in their entirety based on the lowest level of input that is significant to their fair value measurement. No financial assets were measured on a recurring basis as of June 30, 2024, and December 31, 2023. The following tables set forth the financial liabilities measured at fair value on a recurring basis by level within the fair value hierarchy as of June 30, 2024, and December 31, 2023 (in thousands):

The Company did not have any transfers of assets and liabilities between Level 1 and Level 2 of the fair value measurement hierarchy during the six months ended June 30, 2024, and 2023. The following table presents a reconciliation of the derivative liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the six months ended June 30, 2024, and 2023 (in thousands):

Common Stock Warrants

The Company has issued certain warrants to purchase shares of common stock, which are considered derivative liabilities because they have registration rights which could require a cash settlement and are re-measured to fair value at each reporting period in accordance with accounting guidance. As of June 30, 2024, and December 31, 2023, the derivative liability was calculated using the Monte Carlo Simulation valuation.

The assumptions used in estimating the common stock warrant liability using the Monte Carlo simulation valuation model as of June 30, 2024, and December 31, 2023, were as follows:

Other Financial Instruments

The Company’s recorded values of cash and cash equivalents, account and other receivables, accounts payable and accrued liabilities approximate their fair values based on their short-term nature. The recorded value of notes payable approximates the fair value as the interest rate approximates market interest rates.

5. Accrued Liabilities

Accrued liabilities consisted of the following (in thousands):

6. Debt

Business Loan

On July 20, 2021, TA&T entered into a Loan Authorization and Agreement in the amount of approximately $350,000 (the “Business Loan”). The Company made a one-time $35,000 buy down payment when acquiring the loan. The Business Loan bears interest at a rate of 3.75% per annum. The Business Loan is secured by a general security interest in all of the assets of TA&T. The business loan was paid in full during the first quarter of 2023 and there was no outstanding balance at June 30, 2024.

Related Party Debt

TA&T is obligated to repay certain personal loans made by the founders of TA&T to TA&T prior to SINTX’s acquisition of TA&T (the Personal Loans”).

The Company agreed to repay the outstanding balance of the Personal Loans in (i) 24 equal monthly installments beginning September 1, 2022 and each month thereafter until paid in full as one prior owner’s portion of the Personal Loans totaling $157,000, and (ii) for the other owner’s portion of the Personal Loans totaling $193,000. As of June 30, 2024, the related party debt had an outstanding balance of $7,000. The outstanding balance is being paid in monthly installments ending August 1, 2024. The related party debt is not collateralized and has no interest rate.

Insurance Premium Finance Arrangements

In March 2024, in connection with securing Director and Officer professional liability insurance, the Company entered into a Premium Finance Arrangement to extend the premium payment out for a period of 10 months. The Company paid a total of $40,000 up front toward the insurance premium and financed approximately $239,000. The Company will make 10 equal payments under the terms of the Premium Finance Agreement. The Premium Finance Agreement bears interest at an annual percentage rate of 8.510%. As of June 30, 2024, there was an outstanding balance of $139,000.

As of June 30, 2024, there have been 12,360 shares of common stock sold under the 2021 Distribution Agreement for gross proceeds of $1.0 million. Because the company’s public float is less than $75 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.

8. Stock-Based Compensation

A summary of the Company’s outstanding stock option activity for the six months ended June 30, 2024, and 2023 is as follows:

The Company estimates the fair value of each stock option on the grant date using the Black-Scholes-Merton valuation model, which requires several estimates including an estimate of the fair value of the underlying common stock on grant date. The expected volatility was based on an average of the historical volatility of the Company. The expected term was contractual life of option. The risk-free interest rate was based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option. The Company did not grant any stock options during the first quarter of 2023.

Of the 60 options outstanding as of June 30, 2024,18 were awarded to non-executive members of the board of directors.

Unrecognized stock-based compensation as of June 30, 2024, is as follows (in thousands):

9. Commitments and Contingencies

The Company has executed agreements with certain executive officers of the Company which, upon the occurrence of certain events related to a change in control, call for payments to the executives up to three times their annual salary and accelerated vesting of previously granted stock options.

From time to time, the Company is subject to various claims and legal proceedings covering matters that arise in the ordinary course of its business activities. Management believes any liability that may ultimately result from the resolution of these matters will not have a material adverse effect on the Company’s consolidated financial position, operating results or cash flows.

10. Leases

The Company has entered into multiple operating leases from which it conducts its business.

SINTX

With respect to SINTX operations, the Company leases 30,764 square feet of office, warehouse and manufacturing space under a single operating lease. This lease expires in October 2031. The lease has one five-year extension option.

SINTX Armor

On August 19, 2021, the Company, on behalf of SINTX Armor, entered into an Industrial Lease Agreement (the “SINTX Armor Lease”) pursuant to which the Company has agreed to lease approximately 10,936 square feet of office and manufacturing space from which SINTX Armor will conduct its operations. The term of the SINTX Armor Lease is 122 months through October 2031.

TA&T

In connection with operation of its business, TA&T has entered into various leases for approximately 15,840 square feet of office and manufacturing space from which it conducts its research, development and manufacturing activities. The leases have various expiration dates ranging from July 2025 through April 2030. Subsequent to December 31, 2023, we entered into an amended lease agreement reducing this area to 13,560 square feet. The leases have various expiration dates ranging from July 2024 through April 2025.

Leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense is recognized on a straight-line basis over the term of the lease. The Company accounts for lease components separately from the non-lease components. The depreciable life of the assets and leasehold improvements are limited by the expected lease term.

As of June 30, 2024, the operating lease right-of-use assets totaled approximately $3.8 million, and the operating lease liability totaled approximately $3.9 million. Non-cash operating lease expense during the six months ended June 30, 2024 and 2023, totaled approximately $0.3 and $0.4 million, respectively. As of June 30, 2024, the weighted-average discount rate for the Company’s operating lease was 8.7%.

Operating lease future minimum payments together with the present values as of June 30, 2024, are summarized as follows:

On May 23, 2024, the Company announced that its board of directors had declared a 1-for-200 reverse stock split of the company’s common stock. The reverse stock split became effective on May 28, 2024 (the “Effective Date”) at 12:01 AM Eastern. The company’s common stock began trading on a split-adjusted basis on May 28, 2024, under the current trading symbol “SINT.” The reverse stock split was primarily intended to bring the Company into compliance with the minimum bid price requirements for maintaining its listing on the Nasdaq Capital Market. The new CUSIP number for the Company’s shares of common stock following the reverse split will be 829392 703. As a result of the reverse stock split, every 200 shares of the Company’s common stock issued and outstanding were automatically reclassified into one new share of common stock. Proportionate adjustments were made to the conversion and exercise prices and the number of shares underlying the Company’s outstanding warrants, preferred stock, equity awards and the number of shares reserved under the Company’s equity incentive plan. The reverse stock split did not affect the number of authorized shares of common stock or the par value of the common stock. The reverse stock split will affect all stockholders uniformly and will not alter any stockholder’s percentage interest in the company, except to the extent that the reverse stock split would result in a stockholder owning a fractional share. Any fractional shares of common stock resulting from the reverse stock split will be rounded up to the nearest whole share and no stockholders will receive cash in lieu of fractional shares.

NASDAQ Compliance

On June 11, 2024, the Company received notice from The Nasdaq Stock Market LLC (“Nasdaq”) that the Company has evidenced compliance with the $1.00 minimum bid price requirement for continued listing on The Nasdaq Capital Market under Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”). The Company remains subject to a “Mandatory Panel Monitor,” as that term is defined in Listing Rule 5815(d)(4)(B), for a period of one year from June 11, 2024. If, within the one-year period, the Company fails to satisfy the minimum $1.00 closing bid price threshold for 30 consecutive business days, Nasdaq will issue a delist determination rather than provide the Company with a grace period to regain compliance with the Bid Price Rule. In that event, the Company would have the opportunity to request a new hearing to address the deficiency.

Appointment of CEO and President

On August 1, 2024, the board of directors appointed Eric Olson to the office of Chief Executive Officer and President. B. Sonny Bal, MD, continues to serve on the Company’s board of directors in the position of Chairman.

Company-Wide Reduction in Workforce

On August 8, 2024, the Board of Directors approved a plan to implement a Company-wide reduction in workforce. This decision is part of the Company’s ongoing strategic review of its operations aimed at improving operational efficiency and reducing costs. The reduction in force will reduce the number of employees of the Company from 40 to 23. David O’Brien’s employment as the Company’s Executive Vice President and Chief Operating Officer was terminated as part of the reduction in force. The Company is currently assessing the costs associated with this decision, including employee severance. These costs will be disclosed in the Company’s future financial statements as more information becomes available.

Cease Efforts to Make the Armor Plant Operational

On August 12, 2024, the Board of Directors of the Company approved a plan to cease efforts to make the armor plant operational. This decision was made to streamline operations and focus on core business areas that align with the Company’s long-term strategic goals. The armor plant has not been fully operational since the acquisition of the armor equipment in July 2021 and has been completely shut down since October 2023 due to the malfunctioning of the sintering furnace.

In connection with this decision the Company expects to incur an impairment charge of approximately $4.5 million. This charge primarily relates to the write-down of certain long-lived assets associated with the Armor plant to their estimated fair value. The impairment charge will be reflected in the Company’s financial statements for the quarter ended September 30, 2024. The Company is currently assessing other costs associated with this decision, including employee severance and other exit costs. These costs will be disclosed in the Company’s future financial statements as more information becomes available.

The Company’s insurance carrier has determined that a covered loss occurred when the sintering furnace malfunctioned, and coverage is available for the Company’s repair of the sintering furnace. However, the Company’s efforts to fully repair the damaged furnace continue to be delayed. Management will work with the insurance company to continue to fund the repair of the furnace. When the furnace is fully repaired, management hopes to sell the furnace, and related equipment, to a third party. However, the full repair and sale of the furnace, and related equipment, cannot be assured. Therefore, in the calculation of the $4.5 million estimated impairment charge, management has assumed no proceeds will be received from a potential sale of the furnace and related equipment.
