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.

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, 2025, and 2024, the Company incurred a net loss of $2.3 million and $0.9 million, respectively, and used cash in operating activities of $1.3 million and $2.7 million, respectively. The Company had an accumulated deficit of $284 million and $282 million as of March 31, 2025, and December 31, 2024, respectively. We will require substantial future capital in order to continue operating our business, conduct 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 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, decrease expenses and raise additional funding. Whether and when the Company can attain profitability and positive cash flows from operations or obtain additional financing is uncertain.

On February 25, 2021, the Company entered into an Equity Distribution Agreement ( the “ATM Agreement”) with Maxim Group LLC (the “Agent”) as sales agent, as amended on January 10, 2023 and October 12, 2023,pursuant to which the Company, could offer and sell shares of the Company’s common stock, par value $0.01 per share (the “Shares”), initially up to an aggregate offering price of $15,000,000, from time to time in an at-the-market public offering. On March 22, 2024, the Company suspended sales under the ATM Agreement and terminated the continuous offering. On July 11, 2024, the Company filed a Prospectus Supplement with the SEC adjusting the amount available for sale under the ATM Agreement to $3.1 million and shortly thereafter begin offering and selling Shares under the ATM Agreement to the public. During the year ended December 31, 2024, 602,357 Shares were sold under the ATM Agreement for gross proceeds of approximately $3.7 million. Because the Company is subject to General Instruction I.B.6 of Form S-3, it is restricted from selling securities in a public primary offering with a value exceeding one-third of its public float (the market value of our common stock held by our non-affiliates) in any 12-month period so long as its public float remains below $75.0 million. As of December 31, 2024, there was no capacity to offer and sell Shares under the ATM Agreement.

On February 2, 2024, the Company closed 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 entitled to purchase one share of common stock, and one Class F Warrant with each warrant entitled 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 were immediately exercisable at a price of $50.00 per share. The Class E Warrants expire five years from the date of issuance and the Class F Warrants 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 a public offering of 142,000 shares of the Company’s common stock, (the “March 26 Offering”). Each Share was sold at a public offering price of $9.40. The aggregate proceeds to the Company from the March 26 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 a public offering of 358,000 shares of the Company’s common stock, (the “April 5 Offering”). Each Share was sold at a public offering price of $4.20. The aggregate proceeds to the Company from the April 5 Offering were approximately $1.5 million before deducting placement agent fees and other offering expenses payable by the Company.

On February 20, 2025, the Company entered into a private placement transaction with certain institutional and accredited investors for aggregate gross proceeds of $5.0 million, before deducting fees to the placement agent and other expenses payable by the Company in connection with the Private Placement. As part of the Private Placement, the Company issued 1,171,189 shares of the Company’s common stock, par value $0.01 per share (“Common Stock”), pre-funded warrants to purchase 278,098 shares of Common Stock (the “Pre-Funded Warrants”) with an exercise price of $0.0001 per share, and warrants to purchase 1,449,287 shares of Common Stock (the “Common Warrants,” together with the Pre-Funded Warrants, the “Warrants”) (the Warrants, together with the Shares and Warrant Shares (as defined below), the “Securities”) with an exercise price of $3.32 per share. The purchase price per share of Common Stock and the associated Common Warrant was $3.45 and the purchase price per Pre-Funded Warrant and associated Common Warrant was $3.4499. The Common Warrants are exercisable immediately and expire five-and one-half years from issuance. The Pre-Funded Warrants are exercisable immediately and terminate when exercised in full.

We are actively seeking opportunities to raise additional equity and/or debt financing. However, such funding is not guaranteed and may not be available to the Company on favorable or acceptable terms and may involve significant restrictive covenants. Any additional equity financing, 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.

The Board of Directors, together with management, is performing an ongoing evaluation of the Company’s business strategy and focus.

An option being evaluated is a change in strategic emphasis to advancements in the medical device sector. Historically engaged in both industrial and biomedical applications, SINTX would prioritize the development and commercialization of innovative medical devices, leveraging our expertise in advanced ceramics and biomaterials. Such a renewed focus would align with a commitment to improving patient outcomes through the creation of products designed for surgical, orthopedic, and other specialized medical applications. We would concentrate our resources on high-growth areas within the healthcare sector where our proprietary materials and technologies—such as silicon nitride—provide a distinct competitive advantage due to their unique strength, durability, and biocompatibility.

Through this transformation, SINTX’s aim would be to deliver meaningful innovations to the medical community. Our current research and development pipeline is centered on medical-grade devices that incorporate antimicrobial properties, enhanced imaging capabilities, and durability under physiological conditions, which are critical for orthopedic implants, spinal fusion devices, and other surgical tools. If we transition away from industrial applications, we anticipate this strategic shift will enable us to better serve the medical sector, address critical unmet needs, and position SINTX as a leading provider in the medical device market. By focusing on partnerships and collaborations with healthcare institutions and industry leaders, SINTX is positioned to expand its footprint in the medical device sector and drive shareholder value through sustainable, high-impact innovations, however, such a transition has not been approved by the Board of Directors, nor can such approval or successful transition be assured.

SINTX Technologies has initiated discussions with the leaseholder for our Armor location in Salt Lake City, Utah, to explore options for reducing the Company’s overall lease liability. This action aligns with our broader strategy to streamline operating expenses and the option to reallocate resources towards growth initiatives in the medical device sector. While these discussions reflect our commitment to financial optimization, there can be no assurance that negotiations will lead to a reduction in the existing lease liability. The outcome of these discussions remains uncertain, and SINTX will continue to evaluate additional measures to manage long-term obligations in alignment with our strategic objectives.

On August 8, 2024, the Board of Directors approved a plan to implement a Company-wide reduction in the workforce. This decision is part of the Company’s ongoing strategic review of its operations aimed at improving operational efficiency and reducing costs.

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 incurred an impairment charge of approximately $4.6 million during the year ended December 31, 2024. This charge primarily relates to the write-down of certain long-lived assets associated with the armor plant to their estimated fair value.

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 intends 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 $4.6 million impairment charge, management has assumed no proceeds will be received from a potential sale of the furnace and related equipment.

As explained in Note 2, on February 19, 2025, the Company entered into an Entity Acquisition Agreement (“the Agreement”) with Tethon Corporation (“Tethon”), pursuant to which the Company sold to Tethon all of the issued and outstanding shares of TA&T in exchange for the assumption by Tethon of the outstanding liabilities of TA&T. The Company expects that this will have a positive impact on the reduction of the net loss.

Based on the decrease in expenditures from the reduction in force and the increase in cash on February 20, 2025, SINTX management has determined that there is no significant uncertainty of the Company’s ability to continue as a going concern through at least May 15, 2026.

Recent Accounting Pronouncements

ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures

In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The standard is effective for full year 2024 reporting, and for interim reporting beginning in 2025. The adoption of this ASU did not change the way the Company evaluates its reportable segments and, as a result, did not have a material impact on the Company’s segment-related disclosures.

The Company operates as one operating segment.  Operating segments are defined as components of an entity for which separate financial information is regularly evaluated by the chief operating decision maker (“CODM”), which is the Company’s Chief Executive Officer, in deciding how to allocate resources and assess performance.  The Company’s CODM evaluates financial information and resources and assesses the performance of these resources on a consolidated basis.  There is no expense or asset information that is supplemental to information disclosed within the consolidated financial statements, that is regularly provided to the CODM.  The allocation of resources and assessment of performance of the operating segment is based on consolidated net loss and functional expenses as reported on our consolidated statements of operations and comprehensive loss.  Because the Company operates as one operating segment, financial segment information, including expense and asset information, can be found in the consolidated financial statements.

ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” on the topic of income taxes. The standard requires additional disclosure for income taxes. These requirements include: (i) requiring a public entity to disclose specific categories in the rate reconciliation; (ii) disclosure of additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate); (iii) annual disclosure of the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes; (iv) annual disclosure of the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5% of total income taxes paid (net of refunds received); (v) annual disclosure of income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign; and (vi) annual disclosure of income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. For public entities, the guidance is effective for annual periods beginning after December 15, 2024. The Company will adopt this guidance in fiscal 2025 and is in the process of evaluating the new requirements. As a result, the Company has not yet determined the impact this new ASU will have on its disclosures.

ASU 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement—Reporting Comprehensive Income (Topic 220): Disaggregation of Income Statement Expenses,” which requires public business entities, such as the Company, to provide disaggregated disclosure of specific natural expense categories underlying certain income statement expense line items in the notes to the financial statements. The standard identifies five required natural expense categories for disaggregation—employee compensation, depreciation, amortization, inventory expense, and other manufacturing expenses—along with a residual “other” category for remaining amounts within relevant expense captions (e.g., cost of sales, selling, general and administrative expenses). ASU 2024-03 does not alter the expense captions presented on the face of the income statement but enhances footnote disclosures to improve transparency. The standard is effective for annual periods beginning after December 15, 2026, with early adoption permitted, and must be applied prospectively, though retrospective application is optional. An update in ASU 2025-01 clarified that interim period disclosures are not required until annual periods beginning after December 15, 2027. The Company is in the process of evaluating the impact of ASU 2024-03 on its consolidated financial statements. We expect adoption to necessitate modifications to our financial reporting processes and systems to capture and disclose the required disaggregated expense information in the footnotes. Management anticipates that this will enhance the granularity of expense disclosures but does not expect a material effect on our reported financial position or results of operations. We are reviewing our current expense classification practices and data collection capabilities to ensure compliance with the new requirements upon adoption.

The Company has determined that recently issued accounting standards, other than the above discussed, will not have a material impact on its consolidated financial position, results of operations or cash flows.
