Milestone Scientific wishes to ensure that such statements are accompanied by meaningful cautionary statements pursuant to the safe harbor established in the Private Securities Litigation Reform Act of 1995. The forward-looking statements included herein are based on current expectations that involve numerous risks and uncertainties. Milestone Scientific’s plans and objectives are based, in part, on assumptions involving the continued expansion of its business. Assumptions relating to the foregoing involve judgments with respect to, among other things, future economic, competitive and market conditions and future business decisions, all of which are difficult or impossible to predict accurately and many of which are beyond the control of Milestone Scientific. Although Milestone Scientific believes that its assumptions underlying the forward-looking statements are reasonable, any of the assumptions could prove inaccurate. Considering the significant uncertainties inherent in the forward-looking statements included herein, our history of operating losses that are expected to continue, requiring additional funding which we may be unable to raise capital when needed (which may force us to delay, curtail or eliminate commercialization efforts of our CompuFlo Epidural Computer Controlled Anesthesia System), the early stage operations of and relative lack of acceptance of our medical products, relying exclusively on two third parties to manufacture our products, changes to our distribution arrangements exposes us to risks of interruption of marketing efforts and building new marketing channels, changes in our informal manufacturing arrangements made by the manufacturer of our products and disruptions at the manufacturing facility of our manufacturers, including shortages of or delays in obtaining chips and other components, exposes us to risks that may harm our business, raising additional funds by issuing securities or through licensing or lending arrangements may cause dilution to our existing stockholders, restrict our operations or require us to relinquish proprietary rights, if physicians do not accept or use our CompuFlo Epidural Computer Controlled Anesthesia System, our ability to generate revenue from sales will be materially impaired, exposure to the risks inherent in international sales and operations, including China, the changing tariff and trade policies of the United States and China, and developments by competitors may render our products or technologies obsolete or non-competitive, the inclusion of such information should not be regarded as a representation by Milestone Scientific or any other person that the objectives and plans of Milestone Scientific will be achieved. Prospective investors are cautioned that any forward-looking statements are not guarantees of future performance and are subject to risks and uncertainties and the actual results may differ materially from those included within the forward-looking statements because of various factors. Except as required by the federal securities laws, Milestone Scientific undertakes no obligation to revise or update any forward-looking statements, whether as a result of new information, future events or otherwise, to reflect events or circumstances occurring after the date of this Annual Report on Form 10-K.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) NOTE 1 — ORGANIZATION AND BUSINESS All references in this report to “Milestone Scientific,” “us,” “our,” “we,” the “Company” or “Milestone” refer to Milestone Scientific Inc., and its consolidated subsidiaries, Wand Dental, Inc., and Milestone Innovations Inc. and Milestone Education LLC (all described below), unless the context otherwise indicates. Milestone Scientific is the owner of the following registered U.S. trademarks: C ompuDent ® ; CompuMed ® ; CompuFlo ® ; DPS Dynamic Pressure Sensing technology ® ; Milestone Scientific ® ; the Milestone logo ® ; SafetyWand ® ; STA Single Tooth Anesthesia System ® ; and The Wand ® . Milestone Scientific was incorporated in the State of Delaware in August 1989. Milestone Scientific has developed a proprietary, computer-controlled anesthetic delivery device, using The Wand ®, a single use disposable handpiece. The device is marketed in dentistry under the trademarks CompuDent ® and STA Single Tooth Anesthesia System ®, and in medicine under the trademark CompuMed ® . CompuDent ® is suitable for all dental procedures that require a local anesthetic. CompuMed ® is suitable for many medical procedures regularly performed in plastic surgery, hair restoration surgery, podiatry, colorectal surgery, dermatology, orthopedics, and many other disciplines. The dental devices are sold in the United States, Canada, and 49 other countries. Specific medical devices have obtained CE mark approval and can be marketed and sold in most European countries. In June 2017, Milestone Scientific received 510 (k) marketing clearance from the U.S. Food and Drug Administration (FDA) on the CompuFlo ® Epidural Computer Controlled Anesthesia System (“Epidural”). NOTE 2-- GOING CONCERN AND LIQUIDITY Our financial statements have been prepared in conformity with generally accepted accounting principles which contemplate continuation of the Company on a going concern basis. The going concern basis assumes that assets are realized, and liabilities are extinguished in the ordinary course of business at amounts disclosed in the unaudited condensed financial statements. The Company has incurred aggregate losses of approximately $ 132.7 million since its inception. Operating losses were approximately $ 1.1 million and $ 4.6 million for the three and nine months ended September 30, 2025, respectively. As of September 30, 2025, The Company had cash and cash equivalents of approximately $ 1.3 million and working capital of approximately $ 3.1 million. For the nine months ended September 30, 2025, and 2024, cash flows used in operating activities were approximately $ 2.7 million and $ 1.4 million, respectively. Based on our available cash and cash equivalents, recurring losses, accumulated deficit and the need to raise additional capital to finance operations, as of September 30, 2025, we have concluded that there is substantial doubt about our ability to continue as a going concern for a period of one year from the date that these unaudited condensed financial statements are issued. We will seek additional funding through equity financings or debt financings to support our current operating plan. Although management intends to pursue plans to obtain additional funding to finance its operations, and we have successfully raised capital in the past, we may not be able to obtain financing on acceptable terms, or at all. The terms of any financing may adversely affect the holdings or rights of the Company’s stockholders. We are actively pursuing the generation of positive cash flows from operating activities through an increase in revenue from its dental business worldwide, the generation of revenue from its medical devices and disposables business in the United States and worldwide, and a reduction in operating expenses. However, our continued operations will depend on its ability to raise additional capital through various potential sources until it achieves profitability, if ever. 9 NOTE 3 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 1. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The applicable rules and regulations of the Securities and Exchange Commission (SEC) include the accounts of Milestone Scientific and its wholly owned subsidiaries, including Wand Dental (wholly owned) and Milestone Innovations Inc. (wholly owned). All significant intra-entity transactions and balances have been eliminated in the consolidation. 2. Basis of Presentation The unaudited condensed consolidated financial statements of Milestone Scientific have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information with the instructions for Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete annual financial statements. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of regular recurring entries) necessary to present such interim results fairly. Interim results are not necessarily indicative of the results of operations which may be expected for a full year or any subsequent period. These unaudited consolidated financial statements should be read in conjunction with the unaudited consolidated financial statements and notes thereto for the year ended December 31, 2024, included in Milestone Scientific’s Annual Report on Form 10-K. 3. Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions in determining the reported amounts of assets and liabilities, and disclosure of contingent liabilities at the date of the unaudited condensed consolidated financial statements and reported amounts of revenues and expenses during the reporting period. The most significant estimates relate to the inventory valuation and cash flow assumptions regarding evaluations of going concern considerations. The Company bases its estimates on historical experience, known trends and other market-specific or relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates as there are changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates. 4. Revenue Recognition The Company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To achieve revenue recognition, the Company performs the following five steps: i. identification of the promised goods or services in the contract; ii. determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; iii. measurement of the transaction price, including the constraint on variable consideration; iv. allocation of the transaction price to the performance obligations based on estimated selling prices; and v. recognition of revenue when (or as) the Company satisfies each performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. 10 The Company derives its revenues from the sale of its products, primarily dental and medical instruments, handpieces, and other related products. The Company sells its products directly to consumers in the United States and through a global distribution network that includes both exclusive and non-exclusive distribution agreements international. The Company derives its revenues from the sale of its products, primarily dental and medical instruments, handpieces, and other related products. The Company sells its products directly to consumers in the United States and through a global distribution network that includes both exclusive and non-exclusive distribution agreements international. Revenue is recognized at the point of shipment for all sales. The Company has no obligation to product sales for any installation, set-up, or maintenance, these being the responsibility of the buyer. Milestone Scientific’s only obligation after sale is the standard commercial warranty against manufacturing defects if the alleged defective unit is returned within the warranty period. E-Commerce The Company sells its STA Single Tooth Anesthesia Systems® (STA) and handpieces directly to dental offices and dental groups within the United States via an online portal. The Company’s E-Commerce portal accepts online payments via credit and debit cards. The cost of delivery is charged to the customer along with appropriate sales tax. The Company recognizes revenue from product sales at the time the product ships to a customer via a third-party carrier. Sales Returns The Company records allowances for product returns as a reduction of revenue at the time product sales are recorded. Several factors are considered in determining whether an allowance for product returns is required, including the customers’ return rights, the Company’s historical experience with returns, and the amount of product in the distribution channel not consumed by end users and subject to return. The Company relies on historical return rates to estimate returns. Financing and Payment The Company’s payment terms differ by geography and customer, but payments from distributors are required within 90 days or less from the date of shipment. The E-Commerce portal sells directly to end users and accepts online payments via credit and debit cards through a third-party. These payments from the third party are typically settled within two business days. Disaggregation of Revenue The Company operates in two operating segments: Dental and Medical. The Company evaluates each of the two segments based on performance, using segment financial information compiled in Note 10. The profitability of the segment helps the Company evaluate staffing levels, assess available cash for allocation to projects and resources, and make informed decisions on whether the segment’s activities should be modified to align with the Company’s overall near- and long-term strategies. See Note 10 for revenues by geographical market, based on the customer’s location, and product category for the three and nine months ended September 30, 2025, and 2024 respectively. 5. Cash and Cash Equivalents Milestone Scientific considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. As of September 30, 2025 and December 31, 2024, Milestone Scientific has approximately $ 1.3 million and $ 3.3 million, respectively of cash and cash equivalents. As of September 30, 2025, Milestone Scientific had cash in accounts that exceeded the Federal Deposit Insurance Corporation insurance limit of $ 250,000 . 11 6. Accounts Receivable The E-commerce portal sells directly to end users and accepts online payments via credit and debit cards via a third-party credit card processor. These payments are settled within two business days of the transaction. Sales to distributors are on credit terms. The Company estimates losses from the ability or inability of its distributor to make payments on billed. Distributors’ credit sales are due 90 days or less from the date of invoicing. As of September 30, 2025, and December 31, 2024, accounts receivable were recorded, net of allowance for credit losses of $ 10,000 , respectively. 7. Inventories Inventories principally consist of finished goods and parts stated at the lower cost (first-in, first-out method) or net realizable value. Inventory quantities on hand are reviewed quarterly. A provision for excess slow moving, defective, and obsolete inventory is recorded if required based on past and expected future sales, potential technological obsolescence, and product expiration requirements. The valuation allowance creates a new cost basis for the inventory, and it is not subsequently marked up through a reduction in the valuation allowance based on any changes in the underlying facts and circumstances. When the valuation allowance is initially recorded, the increase to the allowance is recognized as an increase in cost of sales. The valuation allowance is only reduced if or when the underlying inventory is sold or destroyed. At this time, the cost of sales recognized would include the previous adjusted cost basis. 8. Convertible Notes Payable, Related Parties The Company accounts for Convertible Notes Payable, Related Parties in accordance with ASC 470, Debt . Based on analysis performed by the Company, no embedded conversion or redemption features required bifurcation as derivatives in accordance with ASC 815, Derivatives and Hedging. 9. Basic and Diluted Net Loss Per Common Share Milestone Scientific presents “basic” earnings (loss) per common share applicable to common stockholders and, if applicable, “diluted” earnings (loss) per common share applicable to common stockholders pursuant to the provisions of ASC 260, “Earnings per Share”. Basic earnings (loss) per common share is calculated by dividing net income or loss applicable to common stockholders by the weighted average number of common shares outstanding and to be issued common shares as follows: 82,322,910 and 82,008,336 for the three and nine months ended September 30, 2025 and 79,966,833 and 80,165,181 for the three and nine months ended September 30, 2024 respectively. The calculation of diluted earnings per common share is like that of basic earnings per common share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if all potentially dilutive common shares, such as those issuable upon the exercise of stock options, were issued during the period. Since Milestone Scientific had net losses in the nine months ended September 30, 2025 and 2024, the assumed effects of the exercise of potentially dilutive outstanding stock options, unissued restricted stock awards (“RSA”), and convertible notes payable, related parties, were not included in the calculation as their effect would have been anti-dilutive. Such outstanding options, convertible notes payable, and RSAs totaled 8,357,969 and 3,684,697 for the nine months ended September 30, 2025, and 2024, respectively. 10. Recent Accounting Pronouncements Recently Issued Accounting Pronouncement In November 2024, the Financial Accounting Standards Board, “FASB”, issued Accounting Standards Update “ASU” 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40) , to improve the disaggregation of expenses within the consolidated statement of operations. The amendments in ASU 2024-03 require disclosures, in the notes to the consolidated financial statements, specified information about certain costs and expenses. The amendments require that at each interim and annual reporting period an entity disclose (a) employee compensation, (b) depreciation, and (c) intangible asset amortization included in each relevant expense caption; include specific amounts that are already required to be disclosed under current generally accepted accounting principles (GAAP) in the same disclosure as the other disaggregation requirements; and disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. The amendments in ASU 2024-03 are effective January 1, 2027, and effective for interim periods beginning January 1, 2028. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company will evaluate the impact of ASU 2024-03 on its consolidated financial statements. In December 2023, FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 provide improvements primarily related to the rate reconciliation and income taxes paid information included in income tax disclosures. The Company would be required to disclose additional information regarding reconciling items equal to or greater than five percent of the amount computed by multiplying pretax income (loss) by the applicable statutory tax rate. Similarly, the Company would be required to disclose income taxes paid (net of refunds received) equal to or greater than five percent of total income taxes paid (net of refunds received). Additionally, the Company would be required to disclose income (loss) from continuing operations before income tax expense disaggregated by foreign and domestic jurisdictions, as well as income tax expense disaggregated by federal, state, and foreign jurisdictions. The amendments in ASU 2023-09 are effective January 1, 2025. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is evaluating the impact of the adoption of the ASU 2023-09 on its consolidated financial statements. 12 Recently Adopted Accounting Pronouncement In November 2023, FASB issued ASU 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures , which provides improvements to reportable segment disclosure requirements, primarily through enhanced disclosures around segment expenses. ASU 2023-07 requires us to disclose significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss. ASU 2023-07 also requires that the Company disclose an amount for other segment items by reportable segment, a description of their composition and provide all annual disclosures about a reportable segment’s profit or loss and assets pursuant to Topic 280 during interim periods. The Company must also disclose the CODM’s title and position, as well as specific information around the measures used by the CODM and an explanation of how the CODM uses the reported measures in assessing segment performance and deciding how to allocate resources. Public entities with a single reportable segment must provide all the disclosures required pursuant to ASU 2023-07 and all existing segment disclosures under Topic 280. The amendments of ASU 2023-07 are effective for us for annual periods beginning January 1, 2024, and effective for interim periods beginning January 1, 2025. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. As of January 1, 2024, the Company adopted ASU 2023-07 within its consolidated financial statements. See Note 10 for more information.

NOTE 6 — CONVERITBLE NOTE PAYABLE, RELATED PARTY On April 9, 2025, the Company issued a series of promissory notes (the “Notes”) in the aggregate amount of $ 800,000 , to Mr. Neal Goldman, Ms. Benedetta Casamento, and Dr. Didier Demesmin, each of whom is a director of the Company. The Notes are due April 9, 2028 , and bear interest at the annual rate of prime less 2.50 %, payable annually. All principal and interest shall be payable in cash and/or shares of common stock at the sole discretion of the Company. The Notes are convertible into shares of common stock by the holder at any time and by the Company at maturity. If the Company sells equity securities for gross proceeds in excess of $ 4,000,000 , the holders may request repayment of their note in either cash, shares of common stock or a combination of cash and shares; provided, that the holders would then be entitled to receive only so much cash as the net proceeds to the Company in such sale of equity securities, after payment of other indebtedness and other uses (other than working capital) specified as a use of the proceeds in the relevant offering or disclosure documentation, shall be in excess of $ 4,000,000 . Upon a liquidation event of the Company, as defined in the Notes which includes a sale of the Company or assets, a merger, reorganization or combination transaction where the shareholders before the transaction own less than 50 % of the Company after the transaction and a liquidation, dissolution or winding-up of the Company, the Notes will be repaid in cash or its portion of any non-cash consideration. The conversion rate for any issuance of shares of common stock will be at the then fair value of a share of common stock, with the fair value being determined with reference to the public market price of a share of common stock based on the average of the 15 most recent trading days, but not less than $ 0.50 . The Notes are unsecured and have typical default terms. As of September 30, 2025, the Notes were convertible into 1,530,612 shares of common stock based on an average trading price of $ 0.52 per share. For the three and nine months ended September 30, 2025, the Company recognized approximately $ 10,000 and $ 19,222 of interest expenses related to convertible note related party respectively. 13 NOTE 7 — STOCKHOLDERS’ EQUITY PUBLIC OFFERING On January 12, 2024 the underwriter exercised its over-allotment option as to 372,110 shares of common stock for net proceeds after discounts and commission of $ 192,156 .

Options may be granted to employees, directors, and consultants of Milestone Scientific for the purchase of shares of common stock at a price not less than the fair market value of common stock on the date of grant. Generally, options become exercisable over three years from the grant date and expire five years after the date of grant. Milestone Scientific recognizes compensation expenses over the requisite service period and in the case of performance-based options over the period of the expected performance.

NOTE 9 — INCOME TAXES The utilization of Milestone Scientific’s net operating losses may be subject to a substantial limitation due to the “change of ownership provisions” under Section 382 of the Internal Revenue Code and similar state provisions. Such limitations may result in the expiration of the net operating loss carry forwards before their utilization. Milestone Scientific has established a 100 % valuation allowance for all its deferred tax assets due to uncertainty as to their future realization. In April 2024, we received approximately $ 2.0 million, net of expenses, from the sale of New Jersey net operating losses (“NOL”), that were eligible for purchase under the State of New Jersey’s Economic Development Authority’s New Jersey Technology Business Tax Certificate Transfer Program (“ NJEDA Program”). For the nine months ended September 30, 2024, the Company recorded approximately $ 2.0 million in gain on sale of net operating losses within the unaudited condensed consolidated statement of operations. Pursuant to the NJEDA program, the Company must retain a physical presence in the state of New Jersey for 5 years after the sale of the NOLs. If the Company does not retain a physical presence during the 5 years after the sale of the NOLs, the Company can be liable to pay the state of New Jersey up to $ 2.2 million of the surrendered NOLs NOTE 10 — SEGMENT AND GEOGRAPHIC DATA Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker. The chief operating decision maker, who is responsible for allocating resources and assessing performance of operating segments, has been identified as the Chief Executive Officer (the “CODM”). The Company conducts its business through two reportable segments: Dental and Medical. These segments offer different products and services to various customer base. The CODM assesses the financial performance of the segment and decides how to allocate resources based on Product sales, net, and operating income (loss). Certain reclassifications have been made to the 2025 unaudited condensed consolidated financial statements to conform to the 2024 unaudited condensed consolidated financial statement presentation. These reclassifications had no effect on net loss or cash flows as previously reported. The Company provides general corporate services to its segments; however, these services are not considered when making operating decisions and assessing segment performance. These services are reported under “Corporate Services” below and these include costs associated with executive management, investor relations, patents, trademarks, licensing agreements, new instruments developments, financing activities and public company compliance. 15 The following tables present information about our reportable and operating segments for the three and nine months ended September 30, 2025, and 2024: SCHEDULE OF REPORTABLE AND OPERATING SEGMENTS Corporate Dental Medical Grand Total Three Months ending September 30, 2025 Corporate Dental Medical Grand Total Product sales, net $ -

Advances on contracts have been classified as current at September 30, 2025 and December 31, 2024. The termination of the manufacturing relationship with any of these manufacturers could have a material adverse effect on Milestone Scientific’s ability to produce and sell its products. Although alternate sources of supply exist, and new manufacturing relationships could be established, Milestone Scientific would need to recover its existing tools or have new tools produced. Establishing new manufacturing relationships could involve significant expense and delay. Any curtailment or interruption of the supply, because of termination of such a relationship, would have a material adverse effect on Milestone Scientific’s financial condition, business, and results of operations. 17 On January 3, 2023, the Company launched an E-Commerce platform selling and shipping STA Single Tooth Anesthesia System® (STA) and handpieces directly to dental offices and dental groups within the U.S. For the three months ended September 30, 2025, and September 30, 2024, E-Commerce accounted for 43 % and 45 % of net product sales, respectively.

(2) Operating Leases The Company identified and assessed the following significant assumptions in recognizing its right-of-use assets and corresponding lease liabilities: ● As the Company’s leases do not provide an implicit rate, the Company estimated the incremental borrowing rate in calculating the present value of the lease payments. The Company has utilized its incremental borrowing rate based on the long-term borrowing costs of comparable companies in the Medical Device industry. ● Since the Company elected to account for each lease component and its associated non-lease components as a single combined lease component, all contract consideration was allocated to the combined lease component. ● The expected lease terms include non-cancellable lease periods. Renewal option periods are not included in the determination of the lease terms as they were not reasonably certain to be exercised. The components of lease expense were as follows: SCHEDULE OF COMPONENTS OF LEASE EXPENSE September 30, 2025 September 30, 2024 September 30, 2025 September 30, 2024 Three Months Nine Months September 30, 2025 September 30, 2024 September 30, 2025 September 30, 2024 Cash paid for operating lease liabilities $ 31,882 $ 30,373 $ 95,645 $ 95,645 Cash paid for finance lease liabilities 3,417 2,685 10,251 8,055 Weighted Average Remaining Lease Term Finance leases (years) 4.50 years 0.29 years Operating leases (years) 1.5 years 2.50 years Weighted-average discount rate – operating leases 9.20 % 9.20 % Weighted-average discount rate – finance leases 9.20 % 9.20 % NOTE 14 — SUBSEQUENT EVENTS On November 7, 2025, Mr. Osser resigned from the Board of Directors.

OVERVIEW Milestone Scientific is a biomedical technology company that patents, designs, develops, and commercializes innovative diagnostic and therapeutic injection technologies for medical and dental applications. Since our inception, we have pioneered proprietary computer-controlled injection systems that are proven, reliable, and well established in clinical use. Our common stock has been listed on the NYSE American since June 1, 2015, under the symbol “MLSS.” The Company’s mission is to redefine the global standard of care for injection techniques by improving precision, efficiency, and patient comfort while reducing the anxiety associated with traditional injections. Our proprietary Dynamic Pressure Sensing (DPS®) Technology System enables controlled flow and real-time pressure monitoring at the needle tip, facilitating safer and more consistent drug delivery and fluid aspiration. This platform supports multiple medical and dental applications, including accurate epidural space identification in regional anesthesia procedures. In dentistry, our Wand® device—marketed as CompuDent® and STA Single Tooth Anesthesia System®—is a single-use disposable handpiece suitable for all local anesthetic procedures. The dental systems are marketed in the United States, Canada, and more than 40 other countries. In medicine, our CompuFlo® Epidural Computer Controlled Anesthesia System has received FDA 510(k) clearance for use in the lumbar, thoracic, and cervical thoracic junction regions of the spine, as well as CE Mark approval for commercialization across most European countries. The recent issuance of a chronology-specific CPT code by the American Medical Association represents a significant advancement, expanding reimbursement potential for epidural procedures using the CompuFlo® system and supporting broader adoption in anesthesia and pain management practices across the United States. Milestone Scientific and its subsidiaries hold over 317 U.S. and international patents, with additional applications pending. These patents encompass innovations in computer-controlled drug delivery, dynamic pressure sensing, automated flow regulation, tissue identification, and anesthetic injection devices. Milestone Scientific remains focused on advancing efforts to achieve the following three primary objectives: · Establishing Milestone’s DPS Dynamic Pressure Sensing (DPS®) technology platform as the standard of care in painless and precise drug delivery—providing, for the first time, objective visual and audible in-tissue pressure feedback—and continuing to expand platform applications. · Transitioning from a research and development organization to a commercially focused medical device company, following the successful FDA clearance of our first medical device. · Expanding the global footprint of our CompuFlo® Epidural and CathCheck® Systems through a targeted field sales force and strategic partnerships with distribution companies worldwide. Our dental devices have been used to administer more than 95 million injections worldwide. Each of our devices is designed with a corresponding single-use disposable handpiece, providing a recurring revenue stream following the initial device sale. Currently, we continue to sell disposable handpieces unique to our legacy products—The Wand® and CompuDent®—to customers who have not yet upgraded to our current dental product, the STA Single Tooth Anesthesia System®. 20 The Single Tooth Anesthesia System (Dental) Since its introduction in early 2007, the STA Single Tooth Anesthesia System® and earlier computer-controlled local anesthetic delivery (C-CLAD) devices have been used to deliver more than 95 million safe, effective, and comfortable injections. The instrument has been favorably evaluated in numerous peer-reviewed clinical studies and publications. There is a growing consensus among users that the STA System is a valuable and beneficial instrument that is positively transforming dental practice worldwide. Medical Market Product In June 2017, Milestone Scientific received FDA clearance to market the CompuFlo® Epidural Computer Controlled Anesthesia System in the United States for epidural injections. In May 2022, the Company received a chronology-specific CPT code for its technology from the American Medical Association, marking an important milestone. Effective January 1, 2023, this temporary tracking code enables clinicians to submit reimbursement claims to healthcare insurers for epidural sterile injections in the lumbar, thoracic, and cervical thoracic junction regions of the spine. This CPT code significantly expands the reimbursement potential for epidural procedures in pain management utilizing the CompuFlo® Epidural System, supporting broader clinical adoption.

The decline in total revenue was primarily attributable to lower international and e-commerce dental sales, partially offset by new contributions from the Company’s re-entry into the China market and modest growth in institutional sales. Revenue from Dental Service Organizations (DSOs), government agencies, and dental schools increased slightly to approximately $83,000 for the three months ended September 30, 2025, compared to $81,000 in the prior-year period, reflecting steady institutional demand. E-commerce dental revenue totaled approximately $1.0 million for the three months ended September 30, 2025, compared to $1.1 million for the same period in 2024, a decrease of approximately $105,000, or 9%. The decline was primarily driven by reduced order volume from certain online distributors and the timing of promotional campaigns during the quarter. International dental revenue decreased to approximately $1.0 million in the third quarter of 2025, compared to $1.2 million in the third quarter of 2024, a reduction of approximately $242,000, or 20%. The decrease was largely the result of slower distributor purchasing activity in certain European markets, partially offset by resumed sales in China. Sales in China for the three months ended September 30, 2025, were approximately $200,000, compared to no sales in the same period of 2024. The increase reflects the Company’s successful efforts to reestablish operations and distribution channels in the region following prior-year market disruptions. Revenue from the medical segment totaled approximately $41,000 for the three months ended September 30, 2025, compared to $47,000 in the same period of 2024, a decrease of approximately $6,000, or 13%. The decline was primarily related to the timing of equipment sales and ongoing efforts to expand awareness and adoption of the Company’s CompuFlo® Epidural and CathCheck® Systems within the U.S. pain management market. 22 Gross Profit for 2025 and 2024 were as follows: 2025 2024 Change Dental $ 1,600,512 $ 1,794,041 $ ( 195,529 ) Medical 40,358 42,179 ( 1,821 ) Total gross profit $ 1,640,870 $ 1,836,220 $ (195,350 ) Consolidated gross profit for the three months ended September 30, 2025, was approximately $1.6 million, compared to $1.8 million for the same period in 2024, representing a decrease of approximately $195,000, or 11%. The decline in gross profit was primarily attributable to lower revenue levels during the quarter, particularly within international and e-commerce dental sales, as well as a slight shift in the sales mix toward lower-margin products and markets. Gross margin remained strong overall, reflecting the Company’s continued focus on cost management and operational efficiency. Selling, general and administrative expenses for 2025 and 2024 were as follows: 2025 2024 Change Dental $ 891,719 $ 883,666 $ 8,053 Medical 316,544 375,189 ( 58,645 ) Corporate 1,530,748 1,805,914 ( 275,166 ) Total selling, general and administrative expenses $ 2,739,011 $ 3,064,769 $ (325,758 ) Consolidated selling, general, and administrative (SG&A) expenses for the three months ended September 30, 2025, were approximately $2.7 million, compared to $3.1 million for the same period in 2024, representing a decrease of approximately $325,000, or 10%. The reduction primarily reflects management’s continued focus on cost containment and operational efficiency. Employee salaries and benefits decreased by approximately $147,000 for the three months ended September 30, 2025, compared to the same period in 2024, primarily due to workforce realignment and headcount optimization. In addition, the Company achieved further savings of approximately $178,000 through reductions in marketing, consulting, professional service fees, insurance, royalties, regulatory, travel, and other general administrative expenses. These cost reduction measures are part of management’s ongoing initiatives to streamline operations, align expenses with current revenue levels, and support the Company’s transition toward sustainable profitability Research and Development for 2025 and 2024 were as follows: 2025 2024 Change Dental $ 15,401 $ 232,056 $ ( 216,655 ) Medical 825 - 825 Corporate - - - Total research and development $ 16,226 $ 232,056 $ (215,830 ) Consolidated research and development (R&D) expenses for the three months ended September 30, 2025, were approximately $16,000, compared to approximately $232,000 for the same period in 2024, representing a decrease of approximately $216,000, or 93%. The decrease reflects management’s strategic decision to delay development activities related to the next-generation STA Single Tooth Anesthesia System® instrument. This temporary reduction in R&D spending allows the Company to focus financial resources on the commercial expansion of existing products and the continued global rollout of its CompuFlo® and CathCheck® Systems, while maintaining flexibility to resume development activities at a later date based on market conditions and strategic priorities. Profit (Loss) from Operations for 2025 and 2024 were as follows: 2025 2024 Change Dental $ 693,392 $ 678,318 $ 15,074 Medical ( 277,011 ) ( 333,010 ) 55,999 Corporate ( 1,550,852 ) ( 1,814,487 ) 263,635 Total loss from operations $ (1,134,471 ) $ (1,469,179 ) $ 334,708 The loss from operations for the three months ended September 30, 2025, was approximately $1.1 million, compared to $1.5 million for the same period in 2024, representing an improvement of approximately $335,000, or 22%. The reduction in operating loss was primarily attributable to lower selling, general, and administrative (SG&A) expenses and reduced research and development (R&D) expenditures during the quarter. Management’s ongoing cost-control initiatives, combined with the Company’s focus on operational efficiency and disciplined spending, contributed to the improvement in quarterly operating performance despite a modest decline in consolidated revenue. 23 Nine months ended September 30, 2025 compared to nine months ended September 30, 2024 Net sales for 2025 and 2024 were as follows: 2025 2024 Change Dental $ 6,791,353 $ 6,544,394 $ 246,959 Medical 124,650 72,020 52,630 Total sales, net $ 6,916,003 $ 6,616,414 $ 299,589 Consolidated revenue for the nine months ended September 30, 2025, was approximately $6.9 million, compared to $6.6 million for the same period in 2024, representing an increase of approximately $300,000, or 5%. The year-over-year improvement was primarily driven by higher international and medical sales, partially offset by declines in e-commerce and institutional dental revenue. Revenue from Dental Service Organizations (DSOs), government agencies, and dental schools totaled approximately $277,000 for the nine months ended September 30, 2025, compared to $316,000 in the prior-year period, reflecting a decrease of approximately $39,000, or 12%. E-commerce dental revenue decreased to approximately $3.3 million for the nine months ended September 30, 2025, from $3.5 million for the same period in 2024, a decline of approximately $239,000, or 7%. The reduction was primarily attributable to lower order volumes and timing differences in recurring purchases from certain online distributors. International revenue for the nine months ended September 30, 2025, was approximately $2.9 million compared to $2.7 million for the same period in 2024, an increase of approximately $211,000, or 8%. Sales in China for the nine months ended September 30, 2025, were approximately $310,000, compared to no sales in the same period of 2024. The increase reflects the Company’s successful efforts to reestablish operations and distribution channels in the region following prior-year market disruptions. Medical revenue also increased, totaling approximately $125,000 for the nine months ended September 30, 2025, compared to $74,000 in the prior-year period, representing an increase of approximately $51,000, or 69%. The increase primarily reflects ongoing progress in expanding the clinical use and adoption of the CompuFlo® Epidural and CathCheck® Systems within the pain management and anesthesia markets. Gross Profit for 2025 and 2024 were as follows: 2025 2024 Change Dental $ 4,783,111 $ 4, 859,275 $ ( 76,164 ) Medical 122,800 64,251 58,549 Total gross profit $ 4,905,911 $ 4,923,526 $ (17,615 ) Consolidated gross profit for the nine months ended September 30, 2025, and 2024 was approximately $4.9 million for each period, reflecting no material change year over year. Stable gross profit performance was primarily the result of consistent product margins, favorable manufacturing cost management, and a balanced sales mix between domestic and international markets. Despite modest fluctuations in regional and product-level revenue, the Company maintained gross margin stability through ongoing operational efficiencies, disciplined pricing strategies, and continued supply chain optimization. Selling, general and administrative expenses for 2025 and 2024 were as follows: 2025 2024 Change Dental $ 3,027,615 $ 2,695, 029 $ 332,586 Medical 1,234,199 1, 411,053 (176,854 ) Corporate 4,764,877 4, 862,144 (97,267 ) Total selling, general and administrative expenses $ 9,026, 691 $ 8,968,226 $ 58, 465 Consolidated selling, general, and administrative (SG&A) expenses for the nine months ended September 30, 2025, and 2024 were approximately $9.0 million in both periods, reflecting a slight net increase of approximately $58,000 year over year. The modest change primarily resulted from higher consulting, professional, and regulatory expenses totaling approximately $611,000, which were largely offset by reductions in employee salaries and benefits, marketing, warehousing, and travel expenses amounting to approximately $552,000. The overall stability in SG&A spending demonstrates management’s ongoing focus on expense control, operational efficiency, and resource optimization, while continuing to support the Company’s commercial initiatives and regulatory compliance activities Research and Development for 2025 and 2024 were as follows: 2025 2024 Change Dental $ 427,297 $ 638, 226 $ ( 210,929 ) Medical 9,838 3,009 6,829 Corporate - - - Total research and development $ 437,135 $ 641,235 $ (204,100 ) Consolidated research and development (R&D) expenses for the nine months ended September 30, 2025, were approximately $437,000, compared to $641,000 for the same period in 2024, representing a decrease of approximately $204,000, or 32%. The decrease primarily reflects the Company’s decision to delay development activities related to the next-generation STA Single Tooth Anesthesia System®. This strategic decision allows the Company to conserve resources and prioritize commercialization efforts for its existing product portfolio, including the continued expansion of the CompuFlo® Epidural and CathCheck® Systems, while maintaining the flexibility to resume product development as market conditions and business priorities warrant. 24 Profit (Loss) from Operations for 2025 and 2024 were as follows: 2025 2024 Change Dental $ 1,328,199 $ 1, 526,020 $ ( 197,821 ) Medical ( 1,121,237 ) (1, 349,811 ) 228,574 Corporate (4, 823,917 ) (4, 890,879 ) 66,962 Total loss from operations $ ( 4,616,955 ) $ (4,714,670 ) $ 97,715 The loss from operations for the nine months ended September 30, 2025, was approximately $4.6 million, compared to $4.7 million for the same period in 2024, representing an improvement of approximately $98,000, or 2%. The modest improvement primarily reflects lower research and development (R&D) expenses during the period, partially offset by slightly higher consulting, professional, and regulatory costs within selling, general, and administrative (SG&A) expenses. Management remains focused on further improving operating results through disciplined expense management, cost optimization initiatives, and the continued expansion of higher-margin product sales across both the dental and medical segments Liquidity and Capital Resources Cash Flows The following table summarizes our sources and uses of cash for the nine months ended: Cash flow: September 30, 2025 September 30, 2024 Change Net cash used in operating activities $ (2,690,498 ) $ (1,408,387 ) $ (1,282,111 ) Net cash (used in) provided by investing activities (12,008 ) 2,969,977 (2,981,985 ) Net cash provided by financing activities 789,749 236,294 553,455 $ (1,912,757 ) $ 1,797,884 $ (3,710,641 ) Operating Activities Net cash used in operating activities increased by approximately $1.3 million for the nine months ended September 30, 2025, compared to the same period in 2024. The increase was primarily driven by a higher net loss of $4.6 million during the period, partially offset by non-cash adjustments and changes in working capital items. Management continues to monitor cash usage closely and implement measures aimed at improving operational efficiency and aligning expenses with revenue growth. In April 2024, we received approximately $2.0 million, net of expenses, from the sale of New Jersey net operating losses (“NOL”), that were eligible for purchase under the State of New Jersey’s Economic Development Authority’s New Jersey Technology Business Tax Certificate Transfer Program (“ NJEDA Program”). For the nine months ended September 30, 2024, the Company recorded approximately $2.0 million in gain on sale of net operating losses within the unaudited condensed consolidated statement of operations. Pursuant to the NJEDA program, the Company must retain a physical presence in the state of New Jersey for 5 years after the sale of the NOLs. If the Company does not retain a physical presence during the 5 years after the sale of the NOLs, the Company can be liable to pay the state of New Jersey up to $2.2 million of the surrendered NOLs Investing Activities Net cash used in investing activities decreased by approximately $3.0 million for the nine months ended September 30, 2025, compared to the same period in 2024. The change was primarily attributable to the sale of $3.0 million in marketable securities during the prior-year period, which increased cash flows in 2024. As of September 30, 2025, the Company held no marketable securities, reflecting a strategic decision to allocate available funds toward supporting ongoing operations and commercialization efforts. Financing Activities Net cash provided by financing activities increased by approximately $553,000 for the nine months ended September 30, 2025, compared to the same period in 2024. The increase primarily resulted from the issuance of $800,000 in convertible notes payable during 2025, compared to $200,000 raised through a public placement offering in 2024. The Company continues to evaluate financing opportunities to support working capital requirements, product commercialization, and potential future growth initiatives. Consideration of Company ’ s ability to continue as a going concern The accompanying financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP), which contemplate the continuation of the Company as a going concern. The going concern basis assumes that assets will be realized and liabilities will be settled in the ordinary course of business at the amounts disclosed in the unaudited condensed financial statements. Since its inception, the Company has incurred aggregate losses of approximately $132.7 million. Operating losses were approximately $1.1 million and $4.6 million for the three and nine months ended September 30, 2025, respectively. As of September 30, 2025, Milestone Scientific had cash and cash equivalents of approximately $1.3 million and working capital of approximately $3.1 million. Net cash flows used in operating activities were approximately $2.7 million and $1.4 million for the nine months ended September 30, 2025, and 2024, respectively. Based on the Company’s available cash resources, recurring operating losses, accumulated deficit, and the need for additional capital to finance ongoing operations. Management has concluded that substantial doubt exists about the Company’s ability to continue as a going concern for a period of one year from the date these unaudited condensed financial statements are issued. Management is actively pursuing additional sources of funding through equity and debt financing to support the Company’s operating plan. Although Milestone Scientific has successfully raised capital in the past, there can be no assurance that additional financing will be available on acceptable terms, or at all. The terms of any such financing may adversely affect the rights or holdings of existing stockholders. The Company continues to focus on generating positive cash flow from operations by increasing revenue from its dental business worldwide, expanding sales of its medical devices and disposables in the United States and abroad, and reducing operating expenses. However, the continuation of operations is dependent upon the Company’s ability to raise additional capital and ultimately achieve sustained profitability. 25 Item 3. Quantitative and Qualitative Disclosures about Market Risk Milestone Scientific is a “smaller reporting company” as defined by Regulation S-K and, as such, is not required to provide the information required by this item. Item 4. Controls and Procedures Evaluation of Disclosure Controls and Procedures Our management, with the participation of our Chief Executive Officer and Principal Accounting Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2025. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), refers to controls and other procedures designed to ensure that information required to be disclosed by a company in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company is accumulated and communicated to management, including the principal executive and principal financial officers (or persons performing similar functions), as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any system of controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving its objectives. Accordingly, management must apply judgment in evaluating the cost-benefit relationship of potential control enhancements. Based on their evaluation, our Chief Executive Officer and Principal Accounting Officer concluded that, as of September 30, 2025, our disclosure controls and procedures were effective at a reasonable assurance level. Changes in Internal Control over Financial Reporting We routinely review and evaluate our internal control over financial reporting and periodically make changes intended to enhance its effectiveness. During the quarter ended September 30, 2025, there were no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 26 Item 1A. Risk Factors Except as disclosed below, there have been no material changes to the risk factors previously disclosed in Part I, Item 1A, of our 2024 Annual Report. Changes to United States tariff and import/export regulations may have a material adverse effect on our business, financial condition, and results of operations. The United States has recently enacted and proposed to enact significant new tariffs, and President Trump has directed various federal agencies to evaluate key aspects of U.S. trade policy to evaluate key aspects of U.S. trade policy to further evaluate key aspects of U.S. trade policy further. There has been and are ongoing discussions and commentaries regarding potential significant changes to U.S. trade policies, treaties, and tariffs. There exists significant uncertainty about the future relationship between the U.S. and other countries with respect to such trade policies, treaties, and tariffs. These developments, or the perception that any of them could occur, may have a material adverse effect on global economic conditions and the stability of global financial markets, and may significantly reduce global trade and, in particular, trade between the impacted nations and the U.S. We source essential elements used in our products from China. We have significant sales in jurisdictions outside the United States. Any of these factors could depress economic activity and restrict our access to suppliers or customers and have a material adverse effect on our business, financial condition, and results of operations. Government Action on tariffs, and other funding, may impede our ability to conduct our research and to raise capital. Early 2025 federal government actions to impose tariffs and limit research grants and other funding, including funding for universities and research enterprises, may cause disruption to our business. These actions include the imposition of tariffs and ending or restructuring government research funding generally or in conjunction with higher learning institution funding. These government actions have been only recently implemented; therefore, the full impact has yet to be realized by the Company. Nonetheless, (i) tariffs are likely to increase the cost of doing business and to make it more difficult to obtain items where imported equipment is required by our own activities and the activities of our collaborative and research partners, and (ii) ending or reducing research funding is likely to make it more challenging to find collaborative research partners to work with us as government funding is an indirect support for our research and product development activities. We also believe that as research funding impacts our collaborative research partners is reduced or withdrawn, it will make raising capital for the Company more difficult, as investors will want to know if the Company will be able to use the proceeds with fully funded entities for product development.
