COMMON STOCK PURCHASE WARRANT

SINTX TECHNOLOGIES, INC.

THIS COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received, Sinaptic Surgical, LLC, a Delaware limited liability company or its assigns (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, to subscribe for and purchase from SINTX Technologies, Inc., a Delaware corporation (the “Company”), up to THREE HUNDRED AND TWENTY FIVE THOUSAND SHARES (as subject to adjustment hereunder, the “Warrant Shares”) of Common Stock.

This Warrant is issued under and in accordance with that certain Asset Purchase Agreement (as such agreement may be amended from time to time, the “APA”), dated June 23, 2025, by and among SINTX Technologies, Inc., a Delaware corporation, and Sinaptic Surgical, LLC., a Delaware limited liability company and Sinaptic Holdings, LLC, a Delaware limited liability company, and is subject to the terms and provisions contained therein. In the event of any conflict or inconsistency between this Warrant and the APA, the APA shall control. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in APA.

The purchase price of one share of Common Stock under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).

Section 1. Vesting and Exercisability of Warrant Shares

a) Vesting Schedule. The Warrant Shares issuable upon exercise of this Warrant shall vest and become exercisable, in whole or in part, upon the occurrence of certain milestone events (each, a “Milestone Event”) as set forth in Section 1.5(a)(1) – (5) of the APA. The date upon which a Milestone Event is achieved shall be referred to herein as an “Exercise Date.” The date of achievement of the Milestone Event set forth in Section 1.5(a)(1) of the APA shall be referred to as the “Initial Exercise Date.”

b) Exercise Period. Once vested, the Warrant Shares may be exercised by the Holder at any time prior to the Termination Date.

c) Notice of Milestone Achievement. The Company shall provide written notice to the Holder within five (5) business days of the occurrence of any Milestone Event, specifying the number of Warrant Shares that have vested as a result.

Notwithstanding anything to the contrary contained herein, the Warrants shall expire at 5:00 p.m. (New York Time) on June 27, 2030 (the “Termination Date”).

Section 2. Exercise.

a) Exercise of Warrant. Once vested in accordance with Section 1, exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the achievement of a Milestone Event and on or before the Termination Date, by delivery to the Company of a duly executed PDF copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (the “Notice of Exercise”). Within the earlier of (i) one (1) Trading Day and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date on which the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise on the Trading Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

b) Exercise Price. The exercise price per share of Common Stock under this Warrant shall be $6.30, subject to adjustment hereunder (the “Exercise Price”).

c) Cashless Exercise. If at any time after ninety (90) days after the Initial Exercise Date there is no effective registration statement registering, or the prospectus contained therein is not available for the resale of the Warrant Shares by the Holder, then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

If Warrant Shares are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the holding period of the Warrant Shares being issued may be tacked on to the holding period of this Warrant. The Company agrees not to take any position contrary to this Section 2(c).

“Bid Price” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the bid price of the Common Stock for the time in question (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported on The Pink Open Market (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

“VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if the OTCQB Venture Market (“OTCQB”) or the OTCQX Best Market (“OTCQX”) is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported on the Pink Open Market (“Pink Market”) operated by the OTC Markets, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

i. Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder or (B) the Warrant Shares are eligible for resale by the Holder without volume or manner-of-sale limitations pursuant to Rule 144 (assuming cashless exercise of the Warrants), and otherwise by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is the earlier of (i) one (1) Trading Day after the delivery to the Company of the Notice of Exercise and (ii) the number of Trading Days comprising the Standard Settlement Period after the delivery to the Company of the Notice of Exercise (such date, the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares, provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within the earlier of (i) one (1) Trading Day and (ii) the number of Trading Days comprising the Standard Settlement Period following delivery of the Notice of Exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. As used herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect on the date of delivery of the Notice of Exercise.

ii. Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

iii. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

iv. Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that, in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. For the avoidance of doubt, the Company shall not be responsible for any tax which may be payable in respect of any transfers involved in the registration of any book entry or certificates for Warrant Shares or Warrants in a name other than that of the Holder. The Company shall pay all Transfer Agent fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares.

v. Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

e) Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within one Trading Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 19.99% of the number of shares of Common Stock outstanding on the Issuance Date. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.

Section 3. Certain Adjustments.

a) Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification; provided that if such record date is fixed and such dividend is not fully paid or such Distribution is not fully made on the date fixed therefor, the Exercise Price shall be recomputed accordingly as of the close of business on such record date and thereafter such Exercise Price shall be adjusted pursuant to this Section 3(a) to reflect the actual payment of such dividends or Distributions.

b) Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

c) Notice to Holder.

i. Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly deliver to the Holder by email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

Section 4. Transfer of Warrant.

a) Transferability. Subject to compliance with any applicable securities laws, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on which the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

b) New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the Initial Exercise Date and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

c) Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

d) Representation by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant to sales registered or exempted under the Securities Act.

Section 5. Miscellaneous.

a) No Rights as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i). Without limiting any rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant to Section 2(c), in no event shall the Company be required to net cash settle an exercise of this Warrant.

b) Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

c) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

d) Authorized Shares.

The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

e) Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the provisions of the Purchase Agreement.

f) Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.

g) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies, notwithstanding the fact that all rights hereunder terminate on the Termination Date. Without limiting any other provision of this Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

h) Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in accordance with the notice provisions of the Purchase Agreement.

i) Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

j) Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

k) Successors and Assigns. Subject to applicable securities laws, and the restrictions on transfer described herein, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

l) Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

m) Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law rule or regulation (including those of Nasdaq), but if any provision of this Warrant shall be prohibited by or invalid under applicable law, rule or regulation, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

n) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

This ASSET PURCHASE AGREEMENT (this “Agreement”) is made and entered into as of June 23, 2025, by and between Sinaptic Surgical, LLC (“Seller”), Sinaptic Holdings, LLC (“Parent”) and SINTX Technologies, Inc. (“Buyer”).

RECITALS

NOW, THEREFORE, in consideration of the mutual representations, warranties, covenants, and agreements contained in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

ARTICLE I. PURCHASE AND SALE OF ASSETS.

Section 1.1. Purchase and Sale of Assets. Upon the terms and subject to the conditions set forth in this Agreement, effective as of the Closing Date Seller shall sell, transfer, assign, convey, and deliver to Buyer, and Buyer shall purchase and acquire from Seller, all of the Acquired Assets, free and clear of all Liens other than Permitted Liens. “Acquired Assets” means all of Seller’s right, title, and interest in and to the following assets used and/or useful in the operation of the Business, but specifically excluding the Excluded Assets:

Section 1.2. “Excluded Assets” means:

Section 1.3. Assumption of Liabilities. On and subject to the terms and conditions of this Agreement, Buyer agrees to assume and become responsible for the Assumed Liabilities as of the Closing. Buyer shall not assume or have any responsibility with respect to any Liability of Seller that is not an Assumed Liability. “Assumed Liabilities” means (a) all Liabilities of Seller arising from and after Closing under the Contracts, (b) all Liabilities of Seller for accrued paid leave as of the Closing Date of the Proposed Future Employees who accept employment with Buyer, such liability not to exceed more than two (2) weeks’ pay for any Proposed Future Employee that accepts employment at Buyer, and (c) those Liabilities disclosed on Schedule 1.3 of the Disclosure Schedules.

Section 1.4. Retained Liabilities. Notwithstanding anything to the contrary contained in Section 1.3 or elsewhere in this Agreement, Seller shall maintain sole responsibility of, and solely shall retain, pay, perform any Liabilities arising out of or relating to the operation of Seller’s business prior to the Closing, any Liability of Seller under this Agreement or any other document executed in connection with the transactions contemplated hereby, including any Liability of Seller for expenses incurred by Seller or its Affiliates in connection with this Agreement, any Liability of Seller based upon Seller’s acts or omissions occurring after the Closing, and any Liabilities other than the Assumed Liabilities (collectively, the “Retained Liabilities”).

Section 1.5. Purchase Price. The purchase price for the Acquired Assets (the “Purchase Price”) shall be as follows:

Section 1.6. Issuance of Shares of Buyer. Concurrently with the Closing, Buyer shall issue to Seller 216,450 shares (the “Transaction Shares”) of Buyer’s Common Stock in exchange for the payment by Seller to Buyer of $750,000 in immediately available funds (the “Share Purchase Price”).

Section 1.7. Restricted Securities. Upon issuance the Common Stock and Warrants, and shares of Common Stock issuable upon the exercise of the Warrants (the “Warrant Shares”), shall be characterized as “restricted securities” under the federal securities laws, and under such laws no portion may be resold without registration except in certain limited circumstances. Upon the terms and subject to the conditions of this Agreement and on the basis of the representations, warranties and agreements contained herein, at the Closing Buyer shall cause its transfer agent to deliver the Common Stock and Warrants to Seller as designated by Seller. The shares of Common Stock issued under Section 1.6, the Warrant Shares and the Warrants shall bear the following restrictive legends:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. SUCH SECURITIES MAY NOT BE SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION WITHOUT AN EXEMPTION UNDER THE SECURITIES ACT OR AN OPINION OF LEGAL COUNSEL REASONABLY ACCEPTABLE TO THE ISSUER THAT SUCH REGISTRATION IS NOT REQUIRED.”

Section 1.8. Allocation. Within sixty (60) days following the Closing Date, Buyer shall prepare and deliver to Seller a proposed allocation of the Purchase Price among the Acquired Assets for federal income tax purposes (the “Proposed Allocation”). The Proposed Allocation shall be prepared in accordance with Section 1060 of the Internal Revenue Code of 1986, as amended (the “Code”), and the Treasury Regulations thereunder. Seller shall have thirty (30) days following receipt of the Proposed Allocation to review and raise any objections in writing.

SINTX Technologies Acquires SiNAPTIC Surgical Assets and IP to Expand into $1.3B Foot and Ankle Fusion Market

Strategic Acquisition Brings Patented Implant Designs, Seasoned Executive Team, and Near-Term Commercial Opportunities

SALT LAKE CITY, Utah – June 24, 2025 – SINTX Technologies, Inc. (NASDAQ: SINT) (“SINTX” or the “Company”), an advanced ceramics company focused on medical device innovation, today announced that it has executed a Definitive Agreement to acquire the surgical business assets of SiNAPTIC Holdings, LLC, a privately held company focused on silicon nitride ceramic manufacturing and innovation. This transaction is a significant milestone in SINTX’s strategy to acquire a potential competitor and drive commercial revenue growth and expand its product portfolio in the foot and ankle fusion market.

Under the terms of the agreement, SINTX has acquired all intellectual property, product designs, and development assets related to six (6) differentiated foot and ankle implant systems. These designs are backed by clinical development and mechanical testing and a 510(k) pre-submission that is expected to accelerate near-term commercial launch activities. The global ankle fusion market, currently valued at approximately $750.5 million, is expected to grow to $1.38 billion by 2032, representing a CAGR of 9.1%, according to industry research.

“This acquisition is transformative for SINTX by adding a family of FDA-reviewed implants, portfolio of new technologies, and capital, accelerating our shift from R&D to revenue generation and commercial scale,” said Eric Olson, CEO of SINTX Technologies. “Additionally, the SiNAPTIC team brings deep expertise in product development, regulatory strategy, and commercialization to support our existing commercial product portfolio—key elements in driving increased value for our shareholders.”

As part of the transaction, key members of the SiNAPTIC Surgical executive team and board of directors will join SINTX in the following roles:

In consideration for the acquired assets, SINTX issued $750,000 in common shares , priced at $3.465 per share which represents a 10% premium to the closing price of the Company’s common stock on Friday, June 20, 2025, along with 325,000 performance-based common stock purchase warrants. The common shares are subject to a six-month lock-up agreement and the Company has committed to file a resale registration statement with the Securities and Exchange Commission registering the resale of the common shares and the common shares issuable on exercise of the common stock purchase warrants. These warrants are exercisable over five years at a strike price of $6.30, and vest upon achieving specific regulatory and commercial milestones, including FDA clearance and revenue targets.

SINTX will manufacture all devices under its FDA-registered and ISO-certified quality system and leverage existing FDA clearances and Master Files to streamline regulatory approvals.

In addition, Dr. Bryan Scheer, Chairman and CEO of SiNAPTIC, will lead a newly formed Clinical Advisory Board to guide ongoing product development and surgeon engagement.

“This acquisition reflects our shared belief in the transformative potential of silicon nitride ceramic-enhanced implants and the strength of our combined teams,” said Dr. Scheer. “Together, we can accelerate the development of disruptive products and deliver meaningful clinical value.”

Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results and financial condition may differ materially from those indicated in the forward-looking statements. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, difficulty in commercializing ceramic technologies and development of new product opportunities. A discussion of other risks and uncertainties that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements can be found in SINTX’s Risk Factors disclosure in its Annual Report on Form 10-K, filed with the SEC on March 19, 2025, and in SINTX’s other filings with the SEC. SINTX undertakes no obligation to publicly revise or update the forward-looking statements to reflect events or circumstances that arise after the date of this report, except as required by law.
