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”), and 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 and Milestone Innovations Inc. 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 10 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 condensed consolidated financial statements contain all adjustments (consisting of normal recurring entries) necessary to present such interim results fairly. Interim results are not necessarily indicative of the results of operations that may be expected for a full year or any subsequent period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2025, 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 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:

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 international distribution agreements.

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 normal 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.

Segments

The Company operates in two operating segments: Dental and Medical. The Company evaluates each of the two segments based on performance, using financial information compiled utilizing the accounting policies listed in Note 3 of this Form 10-Q. 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 9 for segments by geographical market, based on the customer’s location, and product category for the three months ended March 31, 2026 and 2025, 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 March 31, 2026 and December 31, 2025, Milestone Scientific has approximately $1.2 million and $1.1 million, respectively of cash. As of March 31, 2026, Milestone Scientific had cash in accounts that exceeded the Federal Deposit Insurance Corporation insurance limit of $250,000.

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 2 business days of the transactions. Sales to distributors are on credit terms. The Company estimates losses from the ability or inability of its distributor to make payments on bills.

Distributors’ credit sales are due 90 days or less from the date of invoicing. As of March 31, 2026, and December 31, 2025, accounts receivable was recorded, net of allowance for credit losses of $10,000, respectively.

7. Inventories

Inventories principally consist of finished goods and component parts stated at the lower cost (first-in, first-out method) or net realizable value. Inventory quantities on hand are reviewed on a quarterly basis, and 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 which time cost of sales recognized would include the previous adjusted cost basis.

8. 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: 85,041,913 and 81,854,512 for the three months ended March 31, 2026 and 2025, 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 and warrants, were issued during the period. Since Milestone Scientific had net losses in the three months ended March 31, 2026, and 2025, the assumed effects of the exercise of potentially dilutive outstanding stock options, unissued restricted stock awards (“RSA”) and warrants were not included in the calculation as their effect would have been anti-dilutive. Such outstanding options, RSA’s and warrants totaled 8,178,028 and 3,242,906 for the three months ended March 31, 2026 and 2025, respectively.

9. 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 certain 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 financial statements.
