**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", or the "Company") and its wholly-owned subsidiaries, SINTX Armor, Inc. ("SINTX Armor"), SINTX Agribiotech, Inc., Sinaptic Surgical, LLC, and Technology Assessment and Transfer, Inc. (TA&T) through February 19, 2025 (see Note 2), which are collectively referred to as "we" or the "Company." SINTX Technologies is an advanced ceramics company formed in December 1996 that develops and commercializes materials, components, and technologies for medical, industrial and agribiotech applications. SINTX develops silicon nitride (Si₃N₄)-based biomedical solutions for musculoskeletal and antipathogenic medical device applications. The Company also manufactures advanced silicon nitride components for leading industrial customers operating in high-performance and mission-critical applications. SINTX is a global leader in the research, development, and manufacturing of silicon nitride, and its products have been implanted in humans since 2008.

**SINTX Core Business**

**Biomedical Applications**: Since its inception, SINTX has focused on medical-grade silicon nitride. SINTX biomedical products have been shown to be biocompatible, bioactive, antipathogenic, and to exhibit strong bone affinity. Spinal implants made from SINTX silicon nitride have been successfully implanted in humans since 2008 in the U.S., Europe, South America, and Asia. In October 2025, SINTX received U.S. Food and Drug Administration (FDA) 510(k) clearance for the SiNAPTIC® Foot & Ankle Osteotomy Wedge System, enabling SINTX's commercial entry into reconstructive foot and ankle surgery in the U.S. In March 2026, a SiNAPTIC wedge manufactured from Si₃N₄ was utilized in a reconstructive foot and ankle procedure in the U.S. This established clinical use, together with silicon nitride's inherent resistance to bacterial adhesion and strong bone affinity, suggests potential suitability for additional orthopedic and fusion-related applications including arthroplasty implants and dental implants.

**Antipathogenic Applications**: SINTX believes that by incorporating its unique composition of silicon nitride antipathogenic powder into products such as face masks, drapes, filters, sutures, and wound care devices, it is possible to manufacture surfaces that inactivate pathogens, thereby limiting the spread of infection and disease. We presently manufacture advanced ceramic powders and components in our manufacturing facilities based in Salt Lake City, Utah.

**Industrial Applications:** SINTX manufactures advanced silicon nitride ceramic components for industrial customers operating in demanding technical and high-performance environments. The Company's silicon nitride materials are utilized in applications requiring exceptional mechanical strength, thermal stability, wear resistance, and corrosion resistance. Industrial applications have become an increasingly significant component of the Company's commercial activities, with SINTX collaborating with industrial partners to develop precision-engineered ceramic solutions across multiple end markets. The Company believes its expertise in silicon nitride processing, advanced manufacturing, and materials science positions SINTX to support continued growth in industrial applications.

The SINTX Salt Lake City facility is registered with the FDA, is cGMP and ANVISA RDC 665 compliant, as well as being ISO 9001:2015, ISO 13485:2016 certified, and AS9100D certified. The Company's products are primarily sold in the United States.

*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, 2025, filed with the SEC on March 20, 2026. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026. 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, 2025.

*Segment Information*

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 condensed 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 condensed consolidated financial statements.

*Reclassification*

Certain other prior period balances have been reclassified to conform to the current period presentation.

*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 March 31, 2026, 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. 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. The Company continues to seek opportunities to raise additional funding through equity and/or debt financing. However, such funding is not guaranteed and may not be available to the Company on favorable terms and may involve restrictive covenants. If the Company is not able to obtain additional debt or equity financing, the impact on the Company will be material and adverse.

For the three months ended March 31, 2026, and 2025, the Company incurred a net loss of $2.8 million and $2.3 million, respectively, and used cash in operating activities of $2.5 million and $1.3 million, respectively. The Company had an accumulated deficit of $295 million and $292 million as of March 31, 2026, and December 31, 2025, respectively.

The board of directors and management remain aligned in advancing the Company's strategic direction and business objectives. While the Company expects to continue generating a significant portion of its revenues from its industrial business operations, management is increasingly concentrating resources on high-growth areas within the healthcare sector where the Company's proprietary materials and technologies—such as silicon nitride—provide a distinct competitive advantage due to their unique strength, durability, and biocompatibility. The Company believes its established industrial activities provide an important operational and revenue foundation that supports the continued development and commercialization of its medical technologies. Building upon its established advanced materials expertise and recent FDA 510(k) clearance of the SiNAPTIC Foot & Ankle Osteotomy Wedge System, SINTX is focused on commercializing its medical technologies and advancing additional silicon nitride-based compositions and applications for orthopedic, spinal, wound care, and other medical markets in order to expand its footprint in the medical device sector and support long-term shareholder value creation.

As part of the Company's ongoing strategic review of its operations aimed at improving operational efficiency and reducing costs, as discussed in Note 2 to the condensed consolidated financial statements, on February 19, 2025, the Company sold to Tethon all the issued and outstanding shares of TA&T in exchange for the assumption by Tethon of the outstanding liabilities of TA&T.

As discussed in further detail above, in October 2025, the Company received FDA 510(k) clearance for a new foot and ankle osteotomy wedge system, enabling SINTX's commercial entry into reconstructive foot and ankle surgery in the United States. Revenue was recognized during Q1 2026 and is expected to increase throughout 2026.

As discussed in Note 9 to the condensed consolidated financial statements, in October 2025, the Company entered into the 2025 ATM Agreement to sell shares of its common stock from time to time, through an "at the market offering" program, having an aggregate offering price of $6.4 million. Through March 31, 2026, the Company has sold $0.7 million under the ATM, leaving a remaining balance of $5.7 million available under the ATM. Subsequent to March 31, 2026, the Company sold an additional $0.5 million under the ATM.

As discussed in Note 12 to the condensed consolidated financial statements, in October 2025, the Company entered into a sublease agreement to lease the SINTX Armor facility, that is expected to save the Company approximately $1.0 million over the sublease term.

Despite the actions undertaken by management to improve liquidity and operating costs—including the divestiture of non-core operations, implementation of cost improvement initiatives, commercialization of newly cleared medical products, access to capital through the Company's ATM program, and execution of the Armor facility sublease—management has concluded that substantial doubt remains regarding the Company's ability to continue as a going concern for a period of at least 12 months from the date these condensed consolidated financial statements are issued. The Company's ability to continue as a going concern will depend on its ability to generate increased revenues, achieve profitability, obtain additional financing, and successfully execute its strategic business objectives. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

*Recent Accounting Pronouncements* 

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.

**2. Disposition of TA&T**

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 the issued and outstanding shares of TA&T in exchange for the assumption by Tethon of the outstanding liabilities of TA&T. The disposal did not represent a strategic shift that will have a major effect on the Company's operations and financials and, therefore, did not qualify for discontinued operations treatment under ASC 205-20.

The following table summarizes the carrying amounts of the major classes of assets and liabilities of TA&T at the date of sale that were transferred to the Tethon (in thousands):

---

| | |
|:---|:---|
|  | **February 19, 2025** |
| Cash and cash equivalents | $4 |
| Inventories | 8 |
| Accounts receivable | 91 |
| Right of use asset | 376 |
| Property and equipment, net | 248 |
| Other assets | 16 |
| &nbsp;&nbsp;&nbsp;Total assets sold | 743 |
| Accounts payable | (26) |
| Accrued expenses | (275) |
| Operating lease liability | (384) |
| Other liabilities | (34) |
| &nbsp;&nbsp;&nbsp;Total liabilities assumed | (719) |
| Net assets sold | $24 |

---

No consideration was paid other than the assumption by Tethon of the above liabilities. No significant transaction costs were incurred. No earnout or other contingent consideration arrangements were included in the Agreement.

**3. Business Combinations**

On July 1, 2025, the Company entered into an Asset Purchase Agreement with Sinaptic Surgical, LLC ("Sinaptic Surgical") and Sinaptic Holdings, LLC ("Holdings"), pursuant to which the Company agreed to purchase substantially all the assets and assume certain liabilities of Sinaptic Surgical. As consideration for the purchase of the assets under the Asset Purchase Agreement, the Company issued common stock warrants to purchase 325,000 shares of the Company's common stock (the "Warrants"). The Warrants expire five years from the date of issue and have an exercise price of $6.30 per share. The Warrants will become exercisable upon the achievement of certain milestones prior to the expiration of the Warrants. In connection with the Asset Purchase Agreement, Sinaptic Surgical purchased 216,450 shares of the Company's common stock at a purchase price of $3.465 per share in a private placement.

The fair value for the acquired intangible asset was estimated utilizing the income approach, which involves the use of significant estimates and assumptions including projected revenue growth rates, projected earnings, and discount rates.

The following table summarizes the consideration transferred, the estimated fair value of the assets acquired, and liabilities assumed, at the acquisition date (in thousands):

Schedule of Recognized Identified Assets Acquired and Liabilities Assumed

| &nbsp;&nbsp;&nbsp;Accounts payable and other accrued expenses | (20) |
| **Total identifiable net assets** | $875 |
| **Goodwill** | $302 |

---

The Company recognized goodwill of $302,000, which reflects the future benefits of certain synergies, and regulatory and commercialization strategies. Acquired intangible assets are being amortized over the estimated useful life of five years on a straight-line basis.

**4. 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 of approximately 2.8 million and 2.1 million as of March 31, 2026, and 2025, respectively, that were not included in the fully diluted loss per share calculation because they would have been antidilutive.

Below are basic and diluted loss per share data for the three months ended March 31, 2026, which are in thousands, except for share and per share data:

As of March 31, 2026, all inventories were classified as current. Inventories classified as current represent the carrying value of inventories as of March 31, 2026, that management estimates will be sold or used by March 31, 2027.

**6. 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 certain 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:

---

| | |
|:---|:---|
| Level 1 - | quoted market prices for identical assets or liabilities in active markets. |
| Level 2 - | observable prices that are based on inputs not quoted on active markets but corroborated by market data. |
| Level 3 - | unobservable inputs reflecting management's assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. |

---

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 or liabilities (except the derivative liabilities explained above) were measured on a recurring basis as of March 31, 2026, and December 31, 2025. 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 March 31, 2026, and December 31, 2025 (in thousands):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Fair Value Measurements as of March 31, 2026** | **Fair Value Measurements as of March 31, 2026** | **Fair Value Measurements as of March 31, 2026** | **Fair Value Measurements as of March 31, 2026** |

| Derivative liabilities: |  |  |  |  |
| &nbsp;&nbsp;&nbsp;Common stock warrants | $- | $- | $827 | $827 |

---

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 three months ended March 31, 2026, and 2025. 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 three months ended March 31, 2026, and 2025 (in thousands):

| | |
|:---|:---|
|  | **Common Stock**<br> **Warrants** |
| Balance as of December 31, 2024 | $208 |
| Change in fair value | (87) |
| Balance as of March 31, 2025 | $121 |
| Balance as of December 31, 2025 | $827 |
| Change in fair value | (343) |
| Balance as of March 31, 2026 | $484 |

---

*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 March 31, 2026, and December 31, 2025, 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 March 31, 2026, and December 31, 2025 were as follows:

---

| | | |
|:---|:---|:---|
|  | **March 31,**<br> **2026**  | **December 31,**<br> **2025**  |
| Weighted-average risk-free interest rate | 3.74-3.88% | 3.42-3.65% |
| Weighted-average expected life (in years) | 1.55-4.23 | 0.11-4.48 |
| Expected dividend yield | -% | -% |
| Weighted-average expected volatility | 120.00-150.00% | 115.00-175.00% |

---

*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.

**7. Accrued and Other Current Liabilities**

Accrued liabilities consisted of the following (in thousands):

---

| | | |
|:---|:---|:---|
|  | **March 31,<br> 2026** | **December 31,<br> 2025** |
| Payroll and related expense | $530 | $120 |
| Accrued payables | 170 | 50 |
| Other | 192 | 252 |
|  | $892 | $422 |

---

Other current liabilities consisted of deposits for stock issuance of $1.7 million. The stock issuance is related to the 2025 Warrant Inducement (see Note 9), and the stock is held in abeyance, as of March 31, 2026.

**8. Debt**

**9. Equity**

*2025 ATM Agreement*

On October 3, 2025, the Company entered into an At The Market Offering Agreement (the "2025 ATM Agreement") with H.C. Wainwright & Co., LLC, as sales agent ("Wainwright"), to sell shares of its common stock, par value $0.01 per share (the "2025 ATM Shares") from time to time, through an "at the market offering" program under which Wainwright will act as sales agent. The sales, if any, of the 2025 ATM Shares made under the 2025 ATM Agreement will be made 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, including, without limitation, sales made directly on or through the Nasdaq Capital Market or on any other existing trading market for the Company's common stock. The 2025 ATM Shares will be issued pursuant to the Company's shelf registration statement on Form S-3 (File No. 333-274951) initially filed by the Company with the SEC on October 12, 2023, and declared effective by the SEC on November 27, 2023, and related prospectus supplements to be prepared and filed pursuant to Rule 424(b) from time to time in connection with the offer and sale of the Shares. A prospectus supplement, dated October 3, 2025, covering the offer and sale of the 2025 ATM Shares having an aggregate offering price of $6,413,876 was filed with the SEC.

*2025 Warrant Inducement*

On September 8, 2025, the Company entered into an inducement agreement (the "Inducement Letter") with certain holders of the Company's outstanding common stock purchase warrants. Pursuant to the Inducement Letter, the holders agreed to exercise for cash existing warrants to purchase an aggregate of 1,099,431 shares of the Company's common stock at an exercise price of $3.32 per share in consideration of the Company's agreement to issue new common stock purchase warrants to purchase up to an aggregate of 1,649,147 shares of the Company's common stock at an exercise price of $4.79 per share. The warrant holders paid $0.125 per new warrant as consideration for the issuance of the new warrants. The Company received aggregate gross proceeds of approximately $3.8 million from the exercise of the existing warrants, before deducting placement agent fees and other offering expenses payable by the Company.

The Company estimated the fair value of each warrant on the issuance date using the Black-Scholes-Merton valuation model. The aggregate fair value of the new warrants issued as part of the inducement was $6.7 million, which is presented as a deemed dividend on the condensed consolidated statements of operations and the condensed consolidated statements of stockholders' equity (during the three months ended September 30, 2025).

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.

Unrecognized stock-based compensation as of March 31, 2026, is as follows:

**11. 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 awards.

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.

**12. Leases**

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

*SINTX*

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*

The Company, on behalf of SINTX Armor, leases approximately 10,936 square feet of office and manufacturing space from which SINTX Armor conducted its operations. This lease expires in October 2031. Impairment of operating lease right-of-use assets of $0.7 million was recorded during 2024 related to Armor exit costs. In October 2025, the Company entered into a sublease agreement (the "Sublease") with Hayes Performance Systems, Inc., a Delaware corporation ("Hayes"), pursuant to which the Company agreed to sublease to Hayes all of the premises the Company currently leases under its Industrial Lease Agreement dated August 19, 2021 with SLS Industrial Portfolio Owner SLCP, LLC (the "Prime Lease"). The Sublease term commenced on November 1, 2025, and expires on October 31, 2031, unless earlier terminated in accordance with the Sublease or upon termination of the Prime Lease. Under the Sublease, Hayes will pay the Company base rent ranging from approximately $9,700 per month during the first year of the Sublease to approximately $11,300 per month during the final year of the term, plus its proportionate share of operating expenses and taxes, currently estimated at $0.25 per rentable square foot per month. The Sublease provided for a three-month rent deferral totaling approximately $29,200, which will be repaid in six equal monthly installments beginning February 1, 2026. The Sublease is structured as a triple-net arrangement under which Hayes will be responsible for substantially all costs associated with the Subleased Premises, including utilities, maintenance, and insurance.

*TA&T*

In connection with the disposition of TA&T, the lease facilities, including right of use assets and lease liabilities, were transferred to Tethon (see Note 2).

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 March 31, 2026, operating lease right-of-use assets were approximately $2.4 million, and operating lease liability was approximately $3.2 million. Non-cash operating lease expense was immaterial during the three months ended March 31, 2026 and 2025. As of March 31, 2026, the weighted-average discount rate for the Company's operating lease was 8.8%.

Operating lease future minimum payments together with the present values as of March 31, 2026, are summarized as follows (in thousands):

**ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

*You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our consolidated financial statements for the year ended December 31, 2025 and the notes thereto, along with Management's Discussion and Analysis of Financial Condition and Results of Operations, included in our Annual Report on Form 10-K for the year ended December 31, 2025, filed separately with the U.S. Securities and Exchange Commission. This discussion and analysis contains forward-looking statements based upon current beliefs, plans, expectations, intentions and projections that involve risks, uncertainties and assumptions, such as statements regarding our plans, objectives, expectations, intentions and projections. Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth under the "Risk Factors" section of our Annual Report on Form 10-K for the year ended December 31, 2025, and any updates to those risk factors filed from time to time in our Quarterly Reports on Form 10-Q and in other filings with the Securities and Exchange Commission we may make from time-to-time.*

**Overview**

SINTX Technologies is an advanced ceramics company formed in December 1996 that develops, manufactures, and commercializes silicon nitride biomaterials, composites, devices, and related technologies for medical and other high-value applications. SINTX provides biomedical solutions for medical devices specializing in silicon nitride (Si₃N₄) for musculoskeletal and antipathogenic applications. We also manufacture parts made from silicon nitride for customers in the electrical, aerospace and other industrial sectors. SINTX is a global leader in the research, development, and manufacturing of silicon nitride, and its products have been implanted in humans since 2008.

**Components of our Results of Operations**

We manage our business within one reportable segment, which is consistent with how our management reviews our business, makes investment and resource allocation decisions, and assesses operating performance.

**Revenue**

Our product revenue is derived from the manufacture and sale of products. These revenue sources primarily include coatings, materials, and components for aerospace and medical device markets, toll processing services, and government contracts and grants. We generally recognize revenue from sales where control transfers at a point in time as the title and risk of loss passes to the customer, which is at the time the product is shipped. In general, our customer does not have rights of return or exchange.

We believe our product revenue will increase as we complete development and obtain regulatory clearance for our product candidates and secure opportunities to manufacture third party products with silicon nitride.

We also derive grant and contract revenue from awards provided by governmental agencies.

**Cost of revenue**

The expenses that are included in cost of revenue include all in-house manufacturing costs for the products we manufacture.

**Gross profit**

Our gross profit measures our product revenue relative to our cost of revenue.

**Research and development expenses**

Our research and development costs are expensed as incurred. Research and development costs consist of engineering, product development, clinical trials, test-part manufacturing, testing, developing and validating the manufacturing process, manufacturing, facility and regulatory-related costs. Research and development expenses also include employee compensation, employee and non-employee stock-based compensation, supplies and materials, consultant services, and travel and facilities expenses related to research and development activities.

We expect to incur additional research and development costs as we continue to develop new medical devices, related product candidates for antipathogenic applications, and other products which may increase our total research and development expenses.

**General and administrative expenses**

General and administrative expenses consist primarily of salaries, benefits and other related costs, including stock-based compensation for certain members of our executive team and board of directors, and other personnel employed in finance, legal, compliance, administrative, information technology, customer service, executive and human resource departments. General and administrative expenses also include other expenses not part of the other cost categories mentioned above, including facility expenses and professional fees for accounting and legal services.

**RESULTS OF OPERATIONS**

*Revenue*

For the three months ended March 31, 2026, total revenue increased $11,000, or 3%, compared to the same period in 2025. When excluding the total revenue decrease of $109,000 due to the sale of the TA&T subsidiary, the remaining total revenue increased by $120,000, or 46%.

For the three months ended March 31, 2026, product revenue increased $9,000, or 3%, compared to the same period in 2025. When excluding the product revenue decrease of $64,000 due to the sale of the TA&T subsidiary, the remaining product revenue increased by $73,000, or 32%.

During the three months ended March 31, 2026, grant and contract revenue increased $2,000, or 3%, as compared to the same period in 2025. When excluding the grant and contract revenue decrease of $45,000 due to the sale of the TA&T subsidiary, the remaining grant and contract revenue increased by $47,000, or 142%.

*Revenue trends and strategic focus*

Total revenue for the period was relatively consistent with the prior year, reflecting a combination of underlying growth in the Company's continuing operations and the impact of changes to its business portfolio.

Revenue from ongoing product lines and customer activities increased compared to the prior year period, driven by growth in the Company's spine-related product offerings and continued demand within its OEM technical manufacturing business. In addition, activity under grant and contract programs contributed to period-over-period variability.

These increases were partially offset by the absence of revenue associated with the Company's former TA&T subsidiary, which was divested in Q1 2025.

The Company continues to support its OEM technical manufacturing operations as a source of revenue and cash flow, with recent, meaningful pricing actions improving the profitability of this segment. At the same time, the Company remains focused on the long-term commercialization of proprietary silicon nitride-based biomedical devices, including its orthopedic product portfolio.

*Cost of revenue and Gross profit*

For the three months ended March 31, 2026, cost of revenue decreased by $10,000, or 4%, compared to the same period in 2025, primarily due to a continued focus on higher-margin sales.

*Research and development expenses*

For the three months ended March 31, 2026, research and development expenses decreased by $0.8 million, or 67%, compared to the same period in 2025. The decrease was primarily due to a $0.3 million reduction in headcount-related costs and $0.5 million due to the reallocation of certain overhead costs to general and administrative expenses. Historically, a significant portion of our operations was focused on research and development, resulting in the majority of overhead costs being allocated to research and development. As our focus has shifted toward commercialization, a greater portion of these costs is now classified as general and administrative.

*General and administrative expenses*

For the three months ended March 31, 2026, general and administrative expenses increased by $1.2 million, or 92%, compared to the same period in 2025. The increase was primarily due to $1.1 million in higher headcount-related costs, including $0.4 million of non-cash stock-based compensation, as well as the reallocation of certain overhead costs of $0.5 million, as discussed above. These increases were partially offset by decreases of $0.2 million in non-employee stock-based compensation, $0.1 million in impairment cost recognized in 2025, and $0.1 million in other general expenses.

*Sales and marketing expenses*

For the three months ended March 31, 2026, sales and marketing expenses increased by $0.4 million, or 1,895%, compared to the same period in 2025. The increase was primarily due to $0.2 million in higher headcount-related costs, including $0.1 million of non-cash stock-based compensation, as well as a $0.2 million increase in other sales and marketing related costs associated with our product launch.

*Grant and contract expenses*

For the three months ended March 31, 2026, grant and contract expenses increased by $2,000, or 4%, compared to the same period in 2025, primarily due to the increase in grant and contract revenue.

*Other income, net*

For the three months ended March 31, 2026, other income increased by $0.3 million, or 324%, compared to the same period in 2025, primarily due to a $0.3 million increase in other income from the change in value of derivative liabilities.

*Liquidity and capital resources* 

The condensed consolidated financial statements have been prepared assuming we will continue to operate as a going concern. To date, our 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 we will continue to generate operating losses and use cash in operations. Our continuation as a going concern is dependent upon our ability to increase sales, decrease expenses and raise additional funding. We continue to seek opportunities to raise additional funding through equity and/or debt financing. However, such funding is not guaranteed and may not be available to us on favorable terms and may involve restrictive covenants. If we are not able to obtain additional debt or equity financing, the impact on us will be material and adverse.

For the three months ended March 31, 2026, and 2025, we incurred a net loss of $2.8 million and $2.3 million, respectively, and used cash in operating activities of $2.5 million and $1.3 million, respectively. We had an accumulated deficit of $295 million and $292 million as of March 31, 2026, and December 31, 2025, respectively.

The board of directors and management remain aligned in advancing the Company's strategic direction and business objectives. While we expect to continue generating a significant portion of our revenues from our industrial business operations, management is increasingly concentrating 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. We believe our established industrial activities provide an important operational and revenue foundation that supports the continued development and commercialization of our medical technologies. Building upon our established advanced materials expertise and recent FDA 510(k) clearance of the SiNAPTIC Foot & Ankle Osteotomy Wedge System, we are focused on commercializing our medical technologies and advancing additional silicon nitride-based compositions and applications for orthopedic, spinal, wound care, and other medical markets in order to expand our footprint in the medical device sector and support long-term shareholder value creation.

As part of our ongoing strategic review of our operations aimed at improving operational efficiency and reducing costs, as discussed in Note 2 to the condensed consolidated financial statements, on February 19, 2025, we sold to Tethon all the issued and outstanding shares of TA&T in exchange for the assumption by Tethon of the outstanding liabilities of TA&T.

As discussed in further detail above, in October 2025, we received FDA 510(k) clearance for a new foot and ankle osteotomy wedge system, enabling SINTX's commercial entry into reconstructive foot and ankle surgery in the United States. Revenue was recognized during Q1 2026 and is expected to increase throughout 2026.

As discussed in Note 9 to the condensed consolidated financial statements, in October 2025, we entered into the 2025 ATM Agreement to sell shares of our common stock from time to time, through an "at the market offering" program, having an aggregate offering price of $6.4 million. Through March 31, 2026, we have sold $0.7 million under the ATM, leaving a remaining balance of $5.7 million available under the ATM. Subsequent to March 31, 2026, we sold an additional $0.5 million under the ATM.

As discussed in Note 12 to the condensed consolidated financial statements, in October 2025, we entered into a sublease agreement to lease the SINTX Armor facility, that is expected to save us approximately $1.0 million over the sublease term.

Despite the actions undertaken by management to improve liquidity and operating costs—including the divestiture of non-core operations, implementation of cost improvement initiatives, commercialization of newly cleared medical products, access to capital through our ATM program, and execution of the Armor facility sublease—management has concluded that substantial doubt remains regarding our ability to continue as a going concern for a period of at least 12 months from the date these condensed consolidated financial statements are issued. Our ability to continue as a going concern will depend on our ability to generate increased revenues, achieve profitability, obtain additional financing, and successfully execute our strategic business objectives. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

**Cash Flows**

The following table summarizes, for the periods indicated, cash flows from operating, investing and financing activities (in thousands) – unaudited:

---

| | | |
|:---|:---|:---|
|  | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
|  | **2026** | **2025** |
| Net cash used in operating activities | $(2491) | $(1301) |
| Net cash used in investing activities | (7) | (63) |
| Net cash provided by financing activities | 247 | 4266 |
| Net increase (decrease) in cash | $(2251) | $2902 |

---

*Net cash used in operating activities*

Net cash used in operating activities was $2.5 million during the three months ended March 31, 2026, compared to $1.3 million used during the same period in 2025, an increase of $1.2 million. The increase was primarily due to an increase in net loss of $0.5 million, combined with increases in inventories of $0.4 million, change in fair value of derivative liabilities of $0.3 million, accounts receivable of $0.2 million and decreases in non-cash adjustments of $0.2 million for non-employee stock based compensation and $0.1 million in impairment cost. These changes were partially offset by an increase of $0.5 million in employee stock based compensation.

*Net cash used in investing activities*

Net cash used in investing activities was $7,000 during the three months ended March 31, 2026, compared to $63,000 during the same period in 2025, a decrease of $56,000, primarily due to a decrease in purchases of property and equipment.

*Net cash provided by financing activities*

Net cash provided by financing activities was $0.2 million during the three months ended March 31, 2026, compared to $4.3 million provided during the same period in 2025. The $4.0 million decrease to net cash provided by financing activities was primarily due to a decrease in proceeds from issuance of common stock and prefunded warrants of $4.4 million, partially offset by an increase in proceeds from issuance of common stock in connection with ATM of $0.3 million and a decrease in repurchases of common stock into treasury of $0.1 million.

**Indebtedness**

Information with respect to Indebtedness may be found in Note 8 to the condensed consolidated financial statements included in Item 1 of Part I of this report.

**Off-Balance Sheet Arrangements**

This Report includes the certifications of our Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial and Accounting Officer) required by Rule 13a-14 of the Securities Exchange Act of 1934 (the "Exchange Act"). See Exhibits 31.1 and 31.2. This Item 4 includes information concerning the controls and control evaluations referred to in those certifications.

**Evaluation of Disclosure Controls and Procedures**

We maintain disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (the "Exchange Act"), that are designed to ensure that information required to be disclosed in the reports filed or submitted under the Exchange Act, is recorded, processed, summarized, and reported within the time periods specified by the Commission's rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act are properly recorded, processed, summarized and reported within the time periods required by the Commission's rules and forms.

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial and Accounting Officer), of the effectiveness of the design and operation of these disclosure controls and procedures, as such term is defined in Exchange Act Rule 13a-15(e), as of March 31, 2026. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2026, the end of the period covered by this Quarterly Report on Form 10-Q.

**Changes in Internal Control over Financial Reporting**

There were no changes in our internal control over financial reporting that occurred during the first quarter of 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**PART II**

**ITEM 1. LEGAL PROCEEDINGS**

We are not aware of any pending or threatened legal proceeding against us that could have a material adverse effect on our business, operating results or financial condition. The medical device industry is characterized by frequent claims and litigation, including claims regarding patent and other intellectual property rights as well as improper hiring practices. As a result, we may be involved in various legal proceedings from time to time.

**Item 1A. Risk Factors**

**Information regarding risk factors appears in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2025, which was filed with the SEC on March 20, 2026. There have been no material changes from the risk factors previously disclosed in the Annual Report on Form 10-K.**

**ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS**

**Share Repurchase Program**

In November 2024, the Company announced that its board of directors authorized a share repurchase program that would allow the Company to repurchase up to $500,000 of the Company's outstanding common stock. The extent to which the Company repurchases its shares, and the timing of such repurchases, will depend upon a variety of factors, including trading volume, market conditions, legal requirements, business conditions and other factors. The repurchase program may be discontinued at any time, and the program does not obligate the Company to acquire any specific number of shares of its common stock. There were no repurchases of shares under the share repurchase program during the first quarter of 2026. As of March 31, 2026, the maximum dollar value of shares that may yet be purchased under the program was $366,935.
