FORM OF Promissory Note

PROMISSORY NOTE

FOR VALUE RECEIVED, the undersigned, Duos Technologies, Inc., a Florida corporation (“Maker”), whose address is 7660 Centurion Parkway North, Suite 100, Jacksonville, Florida 32256, promises to pay to the order of Duos Technologies Group, Inc., a Florida corporation (“Holder”, which term shall include any subsequent holder hereof), whose address is 7660 Centurion Parkway North, Suite 100, Jacksonville, Florida 32256, the principal sum of Five Million Four Hundred Thirty-Five Thousand Four Hundred Three and 00/100 Dollars ($5,435,403.00) (the “Principal Amount”), together with interest accruing at a simple rate of 5% per annum on the Principal Amount from time to time outstanding. Interest shall be calculated on the basis of a 365-day year for the actual number of days elapsed.

This Promissory Note (this “Note”) is given pursuant to that certain Stock Transfer Agreement of even date herewith, by and between Sandbank Acosta, LLC and Holder (the “Transfer Agreement”), with respect to the transfer of all of the issued outstanding stock of Maker. This Note is the “Note” referred to in the Transfer Agreement.

1. Payments. The Principal Amount and accrued interest hereunder shall be due and payable as follows:

(a) The Principal Amount, together with all accrued but unpaid interest hereunder, shall be immediately due and payable in one balloon payment upon the earlier of (i) a Change of Control (as defined below) and (ii) August __, 2031 (the earlier of the foregoing (i) and (ii), the “Maturity Date”).

As used herein, “Change of Control” means (i) the sale, transfer or other disposition of all or substantially all of the assets of Maker other than to a wholly owned subsidiary of Maker; (ii) the sale, transfer or other disposition (whether by merger, consolidation or otherwise, and whether in a single transaction or a series of related transactions) of a majority of the outstanding equity interests of Maker; or (iii) the sale, transfer or other disposition (whether by merger, consolidation or otherwise, and whether in a single transaction or a series of related transactions) of one or more subsidiaries of Maker if substantially all of the assets of Maker and its subsidiaries taken as a whole are held by such subsidiary or subsidiaries.

(b) All payments hereunder shall be in lawful money of the United States of America in immediately available funds at Holder’s address set forth herein or at such other place as Holder may designate by written notice to Maker. All payments hereunder shall be applied as follows: (i) first, to any fees or other charges owed by Maker hereunder, (ii) second, to accrued and unpaid interest due under this Note, and (iii) the remainder, if any, to the outstanding principal balance of this Note.

(c) Notwithstanding anything in this Note to the contrary, all outstanding principal, interest and other amounts payable hereunder shall be due and payable on the date such amount is declared by Holder to be immediately payable following an Event of Default.

2. Time of the Essence. Time is of the essence of this Note.

3. Prepayments. This Note may be prepaid in full or in part at any time without penalty. Any such prepayment shall reduce the principal and interest otherwise payable hereunder by the amount of such prepayment. Prepayment in part shall not affect, vary or postpone the duty of Maker to pay all obligations when due, and it shall not affect or impair the right of Holder to pursue all remedies available to it hereunder.

4. Right of Setoff. Maker shall be entitled, but not obligated, to recover any Amtrak Overages (as defined below) by setting off such amounts against this Note. If Maker exercises its right of setoff, the amount recovered by Maker shall reduce the principal and interest otherwise payable hereunder by the amount of such setoff; provided, however, that any such setoff shall be applied in the manner set forth in Section 1(b) above. If Maker exercises its right of setoff and subsequently either (a) Maker and Holder agree that all or a portion of such amount should not have been setoff and is owed to Holder, or (b) a judgment is entered that provides that all or a portion of such amount should not have been setoff and is owed to Holder, then Maker shall promptly thereafter pay such amount to Holder, including interest earned thereon from the date of such wrongful setoff. For purposes of this paragraph, “Amtrak Overages” means out-of-pocket expenses required to be paid by Maker during the period commencing on July 1, 2026 and ending on the Maturity Date (such period, the “Overage Lookback Period”) to complete the installation of rail portals in New York and Maryland pursuant to the Amtrak contracts listed in Schedule 4 hereto (the “Amtrak Contracts”), solely to the extent that such expenses exceed the payments received by Maker from Amtrak under the Amtrak Contracts during the Overage Lookback Period.

5. Unsecured Obligation; No Liens. This Note is a general, unsecured obligation of Maker.

6. Representations and Warranties of Maker. Maker represents and warrants, as of the date of this Note, as follows:

(a) Maker is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Florida.

(b) Maker has the requisite power and authority to execute, deliver and perform Maker’s obligations under this Note.

(c) The execution, delivery and performance by Maker of this Note will not violate or be in conflict with, result in a breach of, or constitute a default under, any indenture, agreement or any other instrument to which Maker is a party or by which Maker or any of its assets or properties is bound, or any judgment, decree, order or award of any court, governmental body or arbitrator, or any law, rule or regulation applicable to Maker.

7. Financial Reporting. Commencing with the fiscal year ended December 31, 2026 and continuing with respect to each fiscal year thereafter, Maker shall provide to Holder, not later than 45 days after and as of the end of each fiscal year, Maker’s balance sheet and profit and loss statement, certified by the chief financial officer or other appropriate executive officer of Maker as having been prepared in accordance with generally accepted accounting principles and as presenting fairly the financial condition of Maker as of the date thereof and for the period then ended.

8. Default. The occurrence of any one or more of the following conditions shall each and all constitute an “Event of Default” under this Note:

(a) The Principal Amount, together with all accrued but unpaid interest, is not paid in full within five (5) days after the Maturity Date.

(b) Maker breaches or fails to comply with any of its covenants or other obligations under this Note, other than the obligation to pay the Principal Amount, accrued but unpaid interest thereon or any other amount owed hereunder, and such breach is not cured within ten (10) days after receipt of written notice of such failure or breach.

(c) Any application or petition is filed by or against Maker in connection with any bankruptcy or similar proceeding (which, in the case of an involuntary petition only, is not dismissed or stayed within sixty (60) days after the date of filing same) or if Maker acknowledges its inability or otherwise fails to pay its debts as and when they become due.

Upon the occurrence of an Event of Default, the entire outstanding Principal Amount and accrued and unpaid interest thereon shall become due and payable at once or thereafter, at the option of Holder, without notice to or demand upon Maker, or Holder may exercise any and all other rights available to it under applicable law or under the Transfer Agreement, each of which remedies shall be cumulative. Forbearance to exercise this right with respect to any failure or breach of Maker shall not constitute a waiver of the right as to any subsequent failure or breach. Exercise of this right shall be without notice to Maker, notice of such exercise being hereby expressly waived.

9. Default Interest. During the existence of an Event of Default, all unpaid principal and accrued interest hereunder shall bear interest at the rate of 8% per annum (the “Default Rate”) until paid.

10. Payment of Costs and Attorneys’ Fees. Maker covenants and agrees to pay all and singular the costs, taxes, fees and expenses of every kind and nature, including Holder’s reasonable attorneys’ fees (including on appeal and in bankruptcy), documentary stamp taxes, intangible taxes and other excise taxes, and including Holder’s reasonable attorneys’ fees and costs in enforcing Holder’s rights under this Note. Every such payment made by or on behalf of Holder shall be immediately due and payable by Maker to Holder and shall bear interest from the date of disbursement by Holder at the Default Rate. Nothing contained in this paragraph shall be construed as requiring Holder to advance or spend money for any of the purposes mentioned in this paragraph. Notwithstanding the foregoing, in any litigation or proceeding arising out of or relating to this Note, the prevailing party shall be entitled to recover its reasonable attorneys’ fees and costs (including on appeal and in bankruptcy) from the non-prevailing party.

11. Waivers and Consents. Maker, for itself, its legal representatives, successors and assigns, respectively, hereby expressly waives presentment, demand for payment, notice of dishonor, protest, notice of non-payment, and diligence in collection, and consents that the time of all payments or any part thereof may be extended, rearranged, renewed or postponed by Holder and agrees that Holder shall not be required first to institute any suit or to exhaust any of its remedies against Maker in order to enforce payment of this Note.

12. Governing Law. This Note shall be governed by and construed in accordance with the laws of the State of Florida, without regard to conflicts of law principles thereunder.

13. Limitation of Interest. All agreements between Maker and Holder are expressly limited so that in no contingency or event whatsoever, whether by reason of advancement of the proceeds hereof, acceleration of maturity of the unpaid principal balance hereof, or otherwise, shall the amount paid or agreed to be paid to Holder for the use, forbearance or detention of the money to be advanced hereunder exceed the highest lawful rate permissible under any law which a court of competent jurisdiction may deem applicable. If, from any circumstances whatsoever, fulfillment of any provision of this Note, or by any other agreement referred to herein, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by law which a court of competent jurisdiction may deem applicable thereto, then ipso facto, the obligation to be fulfilled shall be reduced to the maximum limit of such validity, and if for any circumstances whatsoever Holder shall ever receive interest, the amount of which would exceed the highest lawful rate, such amount which would be excessive interest shall be applied to the reduction of the principal balance remaining unpaid hereunder and not to the payment of interest. This provision shall control every other provision of all agreements between Maker and Holder.

14. Documentary and Intangible Taxes. In the event that any intangible tax or documentary stamp tax is due from Holder to any state or other governmental agency or authority because of the execution or holding of this Note, Maker shall, upon demand, reimburse Holder for any such tax paid.

15. Exclusive Venue and Jurisdiction. Any claim, litigation, legal action or other proceeding brought for the enforcement of this Note, or because of an alleged dispute, breach, default or misrepresentation in connection with any provision of this Note, shall lie solely in the state courts of the State of Florida located in Duval County, Florida. Maker and, by its acceptance of this Note, Holder acknowledge that such courts shall have exclusive jurisdiction over any such claim, litigation, legal action or proceeding and hereby waive all (i) objections to personal jurisdiction or venue in such courts, and (ii) claims to the effect that any of such courts constitutes an inconvenient forum.

16. Notices. Any notice required or permitted to be given hereunder shall be given in accordance with Section 19.3 of the Transfer Agreement.

17. Amendments. This Note may not be modified or changed orally, but only by an agreement in writing signed by the party against whom enforcement of such modification or change is sought.

18. Waiver of Jury Trial. MAKER AND, BY ITS ACCEPTANCE OF THIS NOTE, HOLDER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THEIR RIGHTS TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED UPON THIS NOTE OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS NOTE, ANY OTHER AGREEMENT CONTEMPLATED TO BE EXECUTED IN CONJUNCTION HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF ANY PARTY. THE PROVISIONS OF THIS PARAGRAPH HAVE BEEN FULLY NEGOTIATED AND SHALL BE SUBJECT TO NO EXCEPTIONS. NEITHER MAKER NOR HOLDER HAS IN ANY WAY AGREED WITH OR REPRESENTED TO ANY OTHER PARTY THAT THE PROVISIONS OF THIS PARAGRAPH WILL NOT BE FULLY ENFORCED IN ALL INSTANCES.

THIS NOTE IS A BALLOON PAYMENT NOTE WITH ALL PRINCIPAL AND INTEREST IN THE AMOUNT OF $5,435,403.00 IN PRINCIPAL PLUS $1,358,850.75 (IF PAID ON THE STATED MATURITY DATE OF AUGUST 5, 2031) IN INTEREST (TOTAL $6,794,253.75), DUE NO LATER THAN THE MATURITY DATE SET FORTH IN SECTION 1(a). HOLDER IS NOT OBLIGATED TO REFINANCE OR EXTEND THE TERM OF THIS NOTE.

Exhibit 99.1

Duos Technologies Group Completes Sale of Duos Technologies, Inc. to Sandbank Acosta, LLC

Rail Inspection Technology Pioneer to Operate as an Independent, Privately Held Company Under the DuosTI Brand; Javier Acosta Appointed President

JACKSONVILLE, FL / Globe Newswire / August 6, 2026 - Duos Technologies Group, Inc. (“Duos” or the “Company”) (Nasdaq: DUOT), a leading provider of adaptive, modular, and scalable Edge Data Center solutions, today announced that it has completed the sale of its wholly owned rail technology subsidiary, Duos Technologies, Inc. (“DTI”), to Sandbank Acosta, LLC, a Florida limited liability company. Effective with the closing, DTI operates as an independent, privately held company under the DuosTI brand, led by newly appointed President Javier Acosta.

The transaction, which closed on August 5^th, 2026 with effect as of June 30^th, 2026, returns Duos’ original operating business to private ownership as a focused railroad technology enterprise. DTI is a pioneer in machine vision and artificial intelligence-based inspection of moving trains and operates the largest installed base of Railcar Inspection Portals (RIP®) in North America, serving major carriers across the United States, Canada and Mexico. The Company believes DTI holds an extensive patent portfolio covering wayside scanning and AI defect detection and maintains the largest image database of railcar components in the world.

“DTI built the technology that put Duos on the map, and its Railcar Inspection Portals remain the standard for AI-driven train inspection in North America,” said Doug Recker, Chief Executive Officer of the Company. “This transaction completes the strategic repositioning we announced earlier this year, placing the rail business with owners who are singularly focused on its growth while allowing Duos to dedicate its full capital and management attention to scaling our Edge Data Center and AI infrastructure platforms. We wish Javier and the DuosTI team every success and look forward to supporting a smooth transition.”

“I had the privilege of leading the commercialization and field deployment of the Railcar Inspection Portal across the United States, Canada and Mexico, and I am honored to return to lead this exceptional team into its next chapter,” said Javier Acosta, President of DTI. “As DuosTI, we return to our roots as a focused railroad technology company. With the largest installed base of inspection portals in North America, a deep patent portfolio and an unmatched image database, we are well positioned to expand the reach of our inspection services for our railroad customers and the broader industry.”

In connection with the closing, Adrian Goldfarb, the Company’s interim Chief Financial Officer, has stepped down as President of DTI, a role he had held since March 2026 to oversee the business and the divestiture process, with Mr. Acosta assuming the office of President. Mr. Goldfarb holds a 50% membership interest in Sandbank Acosta, LLC, and the sale was accordingly reviewed and approved by the Company’s Board of Directors as a related-party transaction, supported by an independent fairness opinion process undertaken in the second quarter of 2026.

The divestiture completes the strategic repositioning announced by Duos in March 2026 and enables the Company to concentrate its resources on its Edge Data Center and AI infrastructure businesses through Duos Edge AI, Inc. and Duos Technology Solutions, Inc. Duos will provide certain transition services to DTI for a period following the closing to support continuity for DTI’s customers and employees.
