Note 2. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). These statements include all adjustments (consisting of normal recurring adjustments and reclassifications and non-recurring adjustments) which management believes necessary for a fair presentation of the statements and have been prepared on a consistent basis using the accounting policies described in Note 2. Significant Accounting Policies included in the Notes to Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the Securities and Exchange Commission on March 31, 2026 (the “2025 Annual Report”). Certain financial information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted from the Company’s interim unaudited condensed consolidated financial statements. Accordingly, these interim unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2025. The December 31, 2025 consolidated balance sheet is derived from those statements. The interim operating results for the three and six months ended June 30, 2026 are not necessarily indicative of the operating results expected for the full year ending December 31, 2026. The Company follows Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 220 in reporting comprehensive (loss) income. Comprehensive (loss) income is a more inclusive financial reporting methodology that includes disclosure of certain financial information that historically has not been recognized in the calculation of net (loss) income. Since the Company has no items of other comprehensive (loss) income, comprehensive (loss) income is equal to net (loss) income. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Nocopi Technologies, Inc. and its wholly-owned subsidiary, Polymeric Nocopi. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates and Assumptions In preparing the unaudited condensed consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet, and revenues and expenses for the period then ended. Actual results may differ significantly from those estimates. Significant estimates made by management include, but are not limited to, the allowance for credit losses and inventory reserves, the estimates of useful lives for depreciation, valuation of the lease liabilities and related right of use assets, valuation of goodwill, fair value of common stock, valuation of stock-based compensation and valuation allowance associated with deferred tax assets. Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. The reclassified amounts have no impact on the Company’s previously reported financial position or results of operations and relates to the presentation of professional and consulting expenses and compensation and related expenses – general and administrative, separately on the condensed consolidated statements of comprehensive loss previously included in the general and administrative expenses. Accounts Receivable and Allowances for Credit Losses Accounts receivable are uncollateralized customer obligations due under normal trade terms generally requiring payment within 30 days from the invoice date. Customer account balances with invoices dated over 90 days old are considered delinquent. The carrying amount of accounts receivable is reduced by an allowance that reflects management’s best estimate of the amounts that will not be collected. Accounts receivable are presented net of an allowance for credit losses, which is an estimate of amounts that may not be collectible. The Company uses historical loss information based on the aging of receivables, adjusted for management’s expectations about current and future economic conditions, as the basis to determine expected credit losses. Management exercises significant judgment in determining expected credit losses. Key inputs include macroeconomic factors, industry trends, and the creditworthiness of counterparties. Management believes that the composition of receivables at quarter-end is consistent with historical conditions as credit terms and practices and the client base has not changed significantly. The Company has elected to apply the practical expedient provided by ASU No. 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. Under this practical expedient, the Company assumes that current conditions existing as of the balance sheet date do not change over the remaining life of current accounts receivable and current contract assets when developing the reasonable and supportable forecasts used to estimate expected credit losses. The practical expedient was adopted prospectively, and its adoption did not have a material impact on the Company's condensed consolidated financial statements. As of June 30, 2026 and December 31, 2025, the allowance for credit losses was $12,000 for both periods. During the three and six months ended June 30, 2026 and 2025, the Company recorded a direct write-off of accounts receivable into provision for credit losses amounting to $0 for all periods. Prepaid Expenses and Other Current Assets Prepaid expenses and other current assets consist primarily of costs paid for future services which will occur within a year. Prepaid expenses principally include prepayments in cash for insurance, rent, and services which are being amortized over the terms of their respective agreements. Intangible Assets and Goodwill Intangible assets consist of patents, trademarks, and customer lists. These intangible assets were acquired in a stand-alone asset purchase and were initially recognized at cost in connection with the Polymeric Acquisition (see Note 7). The Company's finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives of 10 years, which reflect the period over which the assets are expected to contribute directly or indirectly to future cash flows. The estimated useful lives, residual values, and amortization methods are reviewed at least annually and adjusted prospectively if estimates or expectations change. Costs incurred to renew or extend the life of existing intangible assets are capitalized when the applicable recognition criteria are met, while maintenance and other costs that do not extend the useful life are expensed as incurred. The Company records goodwill as the excess of the purchase price over the fair value of the identifiable net assets acquired in a business combination (see Note 8). Goodwill is not amortized but is evaluated for impairment at least annually and more frequently if events or changes in circumstances indicate that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. The Company may first perform a qualitative assessment to determine whether it is necessary to perform a quantitative impairment test. If a quantitative impairment test is performed, any impairment loss is recognized for the amount by which the carrying amount of the reporting unit exceeds its fair value, limited to the carrying amount of goodwill. Impairment losses recognized for goodwill are not subsequently reversed. Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment is determined by comparing the carrying value of the long-lived assets to the estimated undiscounted future cash flows expected to result from use of the assets and their ultimate disposition. In instances where impairment is determined to exist, the Company writes down the asset to its fair value based on the present value of estimated future cash flows. There was no impairment as of June 30, 2026 and December 31, 2025. Revenue Recognition The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers. Revenue is recognized when control of promised goods or services is transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled. The Company’s revenues are derived from royalties paid by licensees of the Company’s technologies, fees for the provision of technical services to licensees, and from the direct sale of (i) products incorporating the Company’s technologies, such as inks, security paper and pressure-sensitive labels, and (ii) equipment used to support the application of the Company’s technologies. Royalties consist of guaranteed minimum royalties payable by certain licensees and additional royalties which vary based on the licensee’s sales or production of products incorporating the licensed technology. Service fees and product sales revenues vary directly with the number of units provided. Fixed-Fee License Agreements Under certain license agreements, customers are required to pay guaranteed minimum royalties over the term of the contract. Management has determined that these licenses represent the right to use functional intellectual property, as the licensed technology has standalone functionality and does not require ongoing substantive activities affecting its utility. Accordingly, revenue related to guaranteed minimum royalties is recognized at a point in time when the license is made available to the customer, provided the contract is enforceable and collection is probable. Because guaranteed minimum payments are received over multiple years, future payments are discounted to present value when a significant financing component exists. The related interest income is recognized over the collection period using the effective interest method. License Agreements – Future Technology Certain license arrangements provide access to future or evolving ink technologies. Revenue under these agreements is recognized over time as the Company satisfies its performance obligations over the contractual term. Sales-Based Royalties In addition to guaranteed minimum royalties, certain license agreements provide for royalties based on the licensee’s sales or production volumes. Royalties in excess of guaranteed minimum amounts are recognized in the period in which the underlying customer sales occur. Product Sales Revenue from product sales is recognized at a point in time when control transfers to the customer, generally upon shipment under FOB shipping point terms. Significant judgment is required in determining the timing of revenue recognition for license arrangements and in assessing whether a significant financing component exists. Income Taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, Income Taxes. Income tax expense is the total of the current-year income tax due or refundable and the change in the deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of the tax benefit that is greater than fifty percent (50%) likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Management is not aware of any issues that could result in significant payments, accruals, or material deviation from its positions. The Company files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. In general, the statute of limitations of the Company’s U.S. federal tax returns remains open three years after a tax return is filed. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction. Management has concluded that there are no uncertain tax positions that would require recognition in the financial statements. If the Company were to incur an income tax liability in the future, interest on any income tax liability would be reported as interest expense and penalties on any income tax liability would be reported as income taxes. Management’s conclusions regarding uncertain tax positions may be subject to review and adjustment at a later date based upon ongoing analysis or tax laws, regulations and interpretations thereof as well as other factors. The Company currently has no federal or state tax examinations in progress. As of June 30, 2026, the Company’s tax returns for the tax years 2025, 2024 and 2023 remain subject to audit, primarily by the Internal Revenue Service. The Company did not have material unrecognized tax benefits as of June 30, 2026 and does not expect this to change significantly over the next 12 months. The Company will recognize interest and penalties accrued on any unrecognized tax benefits as a component of the provision for income taxes. Stock-Based Compensation Stock-based compensation is accounted for based on the requirements of ASC 718 – “Compensation –Stock Compensation”, which requires recognition in the financial statements of the cost of employee and director services along with non-employee services received in exchange for an award of equity instruments over the period the employee, director or non-employee is required to perform the services in exchange for the award (presumptively, the vesting period). The ASC also requires measurement of the cost of employee, director or non-employee services received in exchange for an award based on the grant-date fair value of the award. Earnings (Loss) per Share In accordance with FASB ASC 260, Earnings per Share, basic earnings (loss) per common share is computed using net earnings (loss) divided by the weighted average number of common shares outstanding for the periods presented. Diluted earnings (loss) per share are computed using weighted average number of common shares plus dilutive common share equivalents outstanding during the period. The potential common shares related to unvested RSUs were excluded from diluted EPS because their effect would be antidilutive. Lease Accounting The Company follows ASC Topic 842, Leases (Topic 842) and applies the package of practical expedients, which permits it not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. In addition, the Company elected not to apply ASC Topic 842 to arrangements with lease terms of 12 months or less. Operating lease right of use assets (“ROU”) represents the right to use the leased asset for the lease term and operating lease liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the adoption date in determining the present value of future payments. Lease expense for minimum lease payments is amortized on a straight-line basis over the lease term and is included in other general and administrative expenses. An amendment to a lease is assessed to determine if it represents a lease modification or a separate contract. Lease modifications are reassessed as of the effective date of the modification. For modified leases, the Company also reassesses the lease classification as of the modification’s effective date. Recently Issued Accounting Pronouncements Not Yet Adopted In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (ASU 2024-03). The new guidance requires disaggregated information about certain income statement expense line items on an annual and interim basis. This guidance will be effective for annual periods beginning the year ended December 31, 2027 and for interim periods thereafter. The new standard permits early adoption and can be applied prospectively or retrospectively. The Company is evaluating the effect that this guidance will have on the Company’s consolidated financial statements and related disclosures. On December 8, 2025, the FASB issued ASU 2025-11 – Interim Reporting (“ASU 2025-11”) which is intended to improve the navigability of the guidance in ASC 270, Interim Reporting, and clarify when it applies. Under the amendments, an entity is subject to ASC 270 if it provides interim financial statements and notes in accordance with GAAP. ASU 2025-11 also addresses the form and content of such financial statements, interim disclosures requirements, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027 and early adoption is permitted. The Company is currently evaluating the impact the adoption of ASU 2025-11 may have on the Company’s consolidated financial statements and related disclosures. On December 17, 2025, the FASB issued ASU 2025-12, Codification Improvements. The amendments in this update are to make other incremental improvements to GAAP and facilitate codification updates for a broad range of topics arising from technical corrections, unintended application of the codification, clarifications, and other minor improvements. The resulting amendments are collectively referred to as “Codification Improvements.” ASU 2025-12 is effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. The Company is currently evaluating the impact the adoption of ASU 2025-12 may have on the Company’s consolidated financial statements and related disclosures.

If the Company were to incur an income tax liability in the future, interest on any income tax liability would be reported as interest expense and penalties on any income tax liability would be reported as income taxes. Management’s conclusions regarding uncertain tax positions may be subject to review and adjustment at a later date based upon ongoing analysis or tax laws, regulations and interpretations thereof as well as other factors. The Company currently has no federal or state tax examinations in progress. As of June 30, 2026, the Company’s tax returns for the tax years 2025, 2024 and 2023 remain subject to audit, primarily by the Internal Revenue Service. The Company did not have material unrecognized tax benefits as of June 30, 2026 and does not expect this to change significantly over the next 12 months. The Company will recognize interest and penalties accrued on any unrecognized tax benefits as a component of the provision for income taxes.

Stock-Based Compensation Stock-based compensation is accounted for based on the requirements of ASC 718 – “Compensation –Stock Compensation”, which requires recognition in the financial statements of the cost of employee and director services along with non-employee services received in exchange for an award of equity instruments over the period the employee, director or non-employee is required to perform the services in exchange for the award (presumptively, the vesting period). The ASC also requires measurement of the cost of employee, director or non-employee services received in exchange for an award based on the grant-date fair value of the award.

Earnings (Loss) per Share In accordance with FASB ASC 260, Earnings per Share, basic earnings (loss) per common share is computed using net earnings (loss) divided by the weighted average number of common shares outstanding for the periods presented. Diluted earnings (loss) per share are computed using weighted average number of common shares plus dilutive common share equivalents outstanding during the period. The potential common shares related to unvested RSUs were excluded from diluted EPS because their effect would be antidilutive.

Lease Accounting The Company follows ASC Topic 842, Leases (Topic 842) and applies the package of practical expedients, which permits it not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. In addition, the Company elected not to apply ASC Topic 842 to arrangements with lease terms of 12 months or less. Operating lease right of use assets (“ROU”) represents the right to use the leased asset for the lease term and operating lease liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the adoption date in determining the present value of future payments. Lease expense for minimum lease payments is amortized on a straight-line basis over the lease term and is included in other general and administrative expenses. An amendment to a lease is assessed to determine if it represents a lease modification or a separate contract. Lease modifications are reassessed as of the effective date of the modification. For modified leases, the Company also reassesses the lease classification as of the modification’s effective date.

Recently Issued Accounting Pronouncements Not Yet Adopted In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (ASU 2024-03). The new guidance requires disaggregated information about certain income statement expense line items on an annual and interim basis. This guidance will be effective for annual periods beginning the year ended December 31, 2027 and for interim periods thereafter. The new standard permits early adoption and can be applied prospectively or retrospectively. The Company is evaluating the effect that this guidance will have on the Company’s consolidated financial statements and related disclosures. On December 8, 2025, the FASB issued ASU 2025-11 – Interim Reporting (“ASU 2025-11”) which is intended to improve the navigability of the guidance in ASC 270, Interim Reporting, and clarify when it applies. Under the amendments, an entity is subject to ASC 270 if it provides interim financial statements and notes in accordance with GAAP. ASU 2025-11 also addresses the form and content of such financial statements, interim disclosures requirements, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027 and early adoption is permitted. The Company is currently evaluating the impact the adoption of ASU 2025-11 may have on the Company’s consolidated financial statements and related disclosures. On December 17, 2025, the FASB issued ASU 2025-12, Codification Improvements. The amendments in this update are to make other incremental improvements to GAAP and facilitate codification updates for a broad range of topics arising from technical corrections, unintended application of the codification, clarifications, and other minor improvements. The resulting amendments are collectively referred to as “Codification Improvements.” ASU 2025-12 is effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. The Company is currently evaluating the impact the adoption of ASU 2025-12 may have on the Company’s consolidated financial statements and related disclosures.

Note 4. Inventories Inventories consists primarily of ink components and is stated at the lower of cost (determined by the first-in, first-out method) or net realizable value. Cost includes material costs, labor, and overhead. Provisions are made for the estimated effect of obsolete and slow-moving inventories on the basis of historical experience, current usage patterns, future demand and marketability of products, inventory levels and turns, and known replacement costs. <table cellpadding="0" cellspacing="0" id="xdx_892_eus-gaap--ScheduleOfUtilityInventoryTextBlock_zOHJ0LH28Sne" style="font: 12pt Arial, Helvetica, Sans-Serif;

Note 5. Long-term Receivables As of June 30, 2026 and December 31, 2025, the Company had long-term receivables of $504,700 and $775,000, respectively, from four licensees, respectively, representing the present value of fixed guaranteed royalty payments that will be payable over varying periods of two through five years that commenced in the second half of 2022 and terminate in the second quarter of 2028. The fixed guaranteed royalty payments result from amendments to license agreements with three existing licensees and a license agreement with a new licensee. The receivable represents the present value of the fixed minimum annual payments due under the license agreements, discounted at the Company's incremental borrowing rate of 6.32% for two licensees that renewed in 2022 and 8.14% for a licensee that renewed in January 2025 and 5.52% for a new licensee in June 2025. The Company renewed one its license agreements on January 1, 2026. While the agreement contractually states an effective date of January 1, 2026, the Company’s management determined that the substantive economics of the arrangement do not change until July 1, 2026, which is the accounting effective date of this agreement. The Company’s management believes that the accounting effective date is a more accurate reflection of the business and the economic nature of the agreement and more properly aligns the expenses associated with entering into the agreement with the corresponding revenue. These agreements grant licenses for the use of certain patented ink technology as it exists at the time that it is granted which is considered functional intellectual property. Under Topic 606, a performance obligation to transfer a license for functional intellectual property is satisfied at a point in time and the fixed consideration could be recognized upfront when the Company transfers control of the licensee if certain criteria are met. Specifically, the minimum royalty guarantee could be recognized upfront if the following conditions are met: <table cellpadding="0" cellspacing="0" style="font: 12pt Arial, Helvetica, Sans-Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 3%; padding-right: 0.8pt"> </td> <td style="text-align: left; width: 2%; padding-right: 0.8pt; vertical-align: top">·</td> <td style="width: 95%; padding-right: 0.8pt; text-align: justify">The royalty payment is fixed or determinable</td></tr> </table> <table cellpadding="0" cellspacing="0" style="font: 12pt Arial, Helvetica, Sans-Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 3%; padding-right: 0.8pt"> </td> <td style="text-align: left; width: 2%; padding-right: 0.8pt; vertical-align: top">·</td> <td style="width: 95%; padding-right: 0.8pt; text-align: justify">Collection of the royalty payment is considered probable</td></tr> </table> <table cellpadding="0" cellspacing="0" style="font: 12pt Arial, Helvetica, Sans-Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 3%; padding-right: 0.8pt"> </td> <td style="text-align: left; width: 2%; padding-right: 0.8pt; vertical-align: top">·</td> <td style="width: 95%; padding-right: 0.8pt; text-align: justify">The licensee has the ability to benefit from the licensed technology</td></tr> </table> The Company determined that the above conditions were met upon execution of the four license agreements. The present value of the fixed guaranteed costs of obtaining the license agreements (sales commissions) was recorded upon renewal of three existing license agreements and a new license agreement with a new licensee. The sales commissions are amortized on a systematic basis consistent with the pattern of revenue recognition for the underlying these license agreements. The unamortized balance as of June 30, 2026 and December 31, 2025, for accrued commission payable was approximately $75,300 and $96,100, respectively, included on the condensed consolidated balance sheet in accrued expenses and accrued expenses, non-current. The current portion of the license agreements in the amount of approximately $568,900 and $599,400, is included in accounts receivable on the balance sheets as of June 30, 2026 and December 31, 2025, respectively.

The long-term receivables are recorded at its present value as of June 30, 2026, and the receivable and imputed interest will be amortized over the term of the license agreements using the effective interest method. The book value approximates the fair value for long-term receivables. The unamortized balance of the long-term receivables as of June 30, 2026 and December 31, 2025 was $504,700 and $775,000, respectively.

Note 6. Property and Equipment Property and equipment acquisitions are stated at cost less accumulated depreciation and amortization. Expenditures for maintenance and repairs are expensed currently, while renewals and betterments that materially extend the life of an asset are capitalized. The cost of assets sold, retired, or otherwise disposed of, and the related allowance for depreciation, are eliminated from the accounts, and any resulting gain or loss is recognized. Depreciation and amortization is charged to expense on the straight-line basis over the estimated useful life of each asset. Leasehold improvements are amortized over the shorter of the lease term or their respective estimated useful lives.

Management concluded that the assets and business operations acquired in the transaction meet the definition of a business under ASC 805 because 1) inputs were acquired 2) substantive processes were acquired 3) outputs existed before acquisition; and 4) the acquired operations are capable of continuing as an ongoing business immediately after acquisition. Accordingly, the Polymeric Acquisition is accounted for as a business combination under ASC 805 using the acquisition method with the Company as the acquiring entity. The Polymeric Acquisition was accounted for under the acquisition method of accounting in accordance with FASB ASC Topic No. 805 Business Combinations, with the Company as the acquiring entity. The acquisition method of accounting requires, among other things, that the assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. In addition, the acquisition method of accounting requires that the consideration transferred be measured at current market prices at the date of the acquisition. Accordingly, the assets acquired and liabilities assumed are recorded as of the acquisition date at their respective fair values and added to those of the Company. The financial statements and reported results of operations of the Company issued after completion of the Polymeric Acquisition will reflect these values. Accordingly, the Company recorded the acquired assets and assumed liabilities at their estimated acquisition-date fair values in accordance with ASC 805 directly on the financial statements of its wholly owned subsidiary, Polymeric Nocopi. In accordance with ASC 805-30-30-7, the Company measured the consideration transferred at its acquisition-date fair value. The equity consideration consisted of <span id="xdx_90D_ecustom--BusinessCombinationConsiderationTransferredNumberOfSharesIssued_c20260517__20260518__us-gaap--BusinessAcquisitionAxis__custom--PolymericNocopiMember_z4tWR8lUTef2" title="Equity consideration shares">500,000 shares of the Company's Common Stock, which were measured at $<span id="xdx_90F_ecustom--BusinessCombinationConsiderationTransferredEquityInterestSharesPrice_c20260517__20260518__us-gaap--BusinessAcquisitionAxis__custom--PolymericNocopiMember_zpDnG5Y7iehe" title="Share price">1.50 per share based on the quoted market price of the Company's Common Stock on the acquisition date, resulting in a fair value of $<span id="xdx_90D_eus-gaap--BusinessCombinationConsiderationTransferredEquityInterestsIssuedAndIssuable_c20260517__20260518__us-gaap--BusinessAcquisitionAxis__custom--PolymericNocopiMember_zeh75aWZFcCa" title="Fair value">750,000. The estimated fair values of assets acquired and liabilities assumed are provisional and are based on the information that was available as of the acquisition date to estimate the fair value of assets acquired and liabilities assumed. The Company believes that information provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed. The Company expects to complete the purchase accounting during the measurement period as additional information becomes available.

Note 10. Income Taxes There was no income tax expense reflected in the results of operations for the six months ended June 30, 2026 and the year ended December 31, 2025 because the Company carried forward net losses for tax purposes. As of June 30, 2026 and December 31, 2025, the Company had federal net operating loss carry forwards of $1,382,000 and $804,000 respectively, and state net operating loss carryforwards of $2,976,000 and $2,757,000 which may be used to offset future taxable income. The remaining federal NOL's will not expire but will be limited to 80% of taxable income. Pennsylvania NOL's began to expire in 2024, with $964,948 expiring by 2032. The remaining Pennsylvania NOL's expire in 20 years and the Florida NOL's will not expire. The tax effects of temporary differences which give rise to deferred tax assets (liabilities) are summarized as follows (in approximate amounts): <table cellpadding="0" cellspacing="0" id="xdx_89F_eus-gaap--ScheduleOfDeferredTaxAssetsAndLiabilitiesTableTextBlock_zDChCNhoGcli" style="font: 12pt Arial, Helvetica, Sans-Serif;

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Deferred tax assets consist primarily of the tax effect of NOL carry-forwards. The Company has provided a full valuation allowance on the deferred tax assets because of the uncertainty regarding its realizability.

The Company has not completed an analysis to determine whether an ownership change has occurred or whether any resulting limitation would materially affect the utilization of its net operating loss carryforwards. If an ownership change has occurred, the amount of net operating loss carryforwards available for future use could be limited. The Company’s policy is to record interest and penalties associated with unrecognized tax benefits as additional income taxes in the condensed consolidated statements of comprehensive loss. The Company did not recognize any interest or penalties during 2026 related to unrecognized tax benefits. Tax years 2023 through 2025 remain open to examination for federal income tax purposes and by other major taxing jurisdictions to which the Company is subject.

Note 12. Commitments and Contingencies Legal Matters From time to time the Company may be involved in claims and legal actions that arise in the ordinary course of business. To the Company’s knowledge, there are no material pending legal proceedings to which the Company is a party or of which any of the Company’s property is the subject. Leases The Company conducts its operations in leased facilities located in King of Prussia, PA under a non-cancelable operating lease expiring on December 31, 2027. The Company entered into a second amendment to the operating lease agreement, effective June 1, 2025, relating to the leased facilities. The second amendment provides for an extension term to December 31, 2027, and for monthly rent payments of, initially, $7,147, escalating annually by 3.5%. The Company has capitalized the present value of the minimum lease payments commencing June 1, 2025, using an estimated incremental borrowing rate of 6.5%. The minimum lease payments do not include common area annual expenses which are considered to be non-lease components. On May 18, 2026, the Company, through its wholly owned subsidiary, Polymeric Nocopi, assumed a two-year lease agreement executed in year 2024 to conduct its operations in leased facilities located in North Kansas City, MO. The Company assumed balances of the ROU assets and lease liabilities of $117,458 through the Polymeric Acquisition (see Note 8) based on an weighted average incremental borrowing rate of approximately 4%. Simultaneously, on May 18, 2026, the Company, through its wholly owned subsidiary, Polymeric Nocopi, entered into an amendment agreement due to the Polymeric Acquisition (see Note 8) and extended the lease term of the above lease agreement for an additional two-year period which will expire on December 31, 2028. The May 2026 amendment qualifies as a partial termination because it alters the contractual terms and does not create a separate lease since no new right of use was granted and lease payments did not increase to reflect a new right. This represents a partial termination of the existing lease as defined in ASC 842-10-25-13. Accordingly, the Company recalculated the lease liability for the shortened term (from May 2023 to December 2028) using the incremental borrowing rate as of May 18, 2026 of 6.5%, derecognized the carrying amounts of the ROU asset and lease liability of $117,458 associated with the terminated portion and recognized a new ROU asset and lease liability for the amended term of $473,183. As of June 30, 2026 and December 31, 2025, the operating lease ROU asset amounted to approximately $568,900 and $161,300, respectively. As of June 30, 2026 and December 31, 2025, total operating lease liability amounted approximately $577,700 and $168,900, respectively, consisting of current portion of approximately $249,500 and $80,200, respectively, and non-current portion of approximately $328,200 and $88,700, respectively. Total operating lease costs were $46,500 and $20,400 for the three months ended June 30, 2026 and 2025, respectively, and approximately $68,100 and $40,000 for the six months ended June 30, 2026 and 2025, respectively. Undiscounted future minimum lease payments as of June 30, 2026, by year and in aggregate are approximately as follows: <table cellpadding="0" cellspacing="0" id="xdx_894_eus-gaap--LesseeOperatingLeaseLiabilityMaturityTableTextBlock_z0EaMJkihKte" style="font: 9pt Times New Roman, Times, Serif; border-collapse: collapse; width: 100%" summary="xdx: Disclosure - Commitments and Contingencies (Details)"> <tr style="vertical-align: bottom"> <td colspan="2" style="font-size: 12pt; text-align: left">Schedule of maturities of lease payments</td><td style="padding-bottom: 1pt; font-size: 12pt"> </td><td style="padding-bottom: 1pt"> </td> <td colspan="2"> </td><td style="padding-bottom: 1pt"> </td></tr> <tr style="vertical-align: bottom"> <td style="padding-bottom: 1pt; font-weight: bold; text-align: left"> </td><td style="border-bottom: Black 1pt solid; font-weight: bold; text-align: left">Year ending December 31</td><td style="padding-bottom: 1pt; font-weight: bold; text-align: left"> </td><td style="padding-bottom: 1pt"> </td> <td style="padding-bottom: 1pt; text-align: left"> </td><td style="border-bottom: Black 1pt solid; text-align: right">Operating Leases</td><td style="padding-bottom: 1pt; text-align: left"> </td></tr> <tr style="vertical-align: bottom; background-color: rgb(204,238,255)"> <td style="width: 1%; text-align: left"> </td><td style="width: 79%; text-align: left">2026</td><td style="width: 1%; text-align: left"> </td><td style="width: 1%"> </td> <td style="width: 1%; text-align: left">$</td><td id="xdx_987_eus-gaap--LesseeOperatingLeaseLiabilityPaymentsRemainderOfFiscalYear_iI_c20260630_zkPeFcYXMha4" style="width: 14%; text-align: right" title="2026">134,600</td><td style="width: 1%; text-align: left"> </td></tr> <tr style="vertical-align: bottom; background-color: White"> <td style="text-align: left"> </td><td style="text-align: left">2027</td><td style="text-align: left"> </td><td> </td> <td style="text-align: left"> </td><td id="xdx_98F_eus-gaap--LesseeOperatingLeaseLiabilityPaymentsDueNextTwelveMonths_iI_c20260630_zZufHjNnlCEb" style="text-align: right" title="2027">290,400</td><td style="text-align: left"> </td></tr> <tr style="vertical-align: bottom; background-color: rgb(204,238,255)"> <td style="padding-bottom: 1pt; text-align: left"> </td><td style="padding-bottom: 1pt; text-align: left">2028</td><td style="padding-bottom: 1pt; text-align: left"> </td><td style="padding-bottom: 1pt"> </td> <td style="border-bottom: Black 1pt solid; text-align: left"> </td><td id="xdx_989_eus-gaap--LesseeOperatingLeaseLiabilityPaymentsDueYearTwo_iI_c20260630_zuJDi7EzQGGi" style="border-bottom: Black 1pt solid; text-align: right" title="2028">198,600</td><td style="padding-bottom: 1pt; text-align: left"> </td></tr> <tr style="vertical-align: bottom; background-color: White"> <td style="text-align: left"> </td><td style="text-align: left">Total lease payments</td><td style="text-align: left"> </td><td> </td> <td style="text-align: left"> </td><td id="xdx_98C_eus-gaap--LesseeOperatingLeaseLiabilityPaymentsDue_iI_c20260630_z0jAVMlMhDe5" style="text-align: right" title="Total lease payments">623,600</td><td style="text-align: left"> </td></tr> <tr style="vertical-align: bottom; background-color: rgb(204,238,255)"> <td style="padding-bottom: 1pt; text-align: left"> </td><td style="padding-bottom: 1pt; text-align: left">Less imputed interest</td><td style="padding-bottom: 1pt; text-align: left"> </td><td style="padding-bottom: 1pt"> </td> <td style="border-bottom: Black 1pt solid; text-align: left"> </td><td id="xdx_981_eus-gaap--LesseeOperatingLeaseLiabilityUndiscountedExcessAmount_iNI_di_c20260630_zwlg1xTK3e62" style="border-bottom: Black 1pt solid; text-align: right" title="Less imputed interest">(45,900</td><td style="padding-bottom: 1pt; text-align: left">)</td></tr> <tr style="vertical-align: bottom; background-color: White"> <td style="padding-bottom: 2.5pt; text-align: left"> </td><td style="padding-bottom: 2.5pt; text-align: left">Total</td><td style="padding-bottom: 2.5pt; text-align: left"> </td><td style="padding-bottom: 2.5pt"> </td> <td style="border-bottom: Black 2.5pt double; text-align: left">$</td><td id="xdx_983_eus-gaap--OperatingLeaseLiability_iI_c20260630_z7jNQxXlYEFl" style="border-bottom: Black 2.5pt double; text-align: right" title="Total">577,700</td><td style="padding-bottom: 2.5pt; text-align: left"> </td></tr> </table>

Note 13. Segment Reporting The Company uses “the management approach” in determining reportable operating segments. Operating segments are defined as components of an entity where discrete financial information is evaluated regularly by the chief operating decision maker (“CODM”). The management approach considers the internal organization and reporting used by the Company’s CODM for making operating decisions and assessing performance as the source for determining the Company’s reportable segments. The Company’s CODM is the chief executive officer of the Company, who reviews operating results to make decisions about operating decisions, allocating resources and assessing performance for the entire Company. The CODM reviews and utilizes consolidated financial information, including revenue, gross profit, operating income (loss) and net income (loss) as reported on the condensed consolidated statements of comprehensive loss, to assess performance and allocate resources to support strategic priorities. Consolidated net income (loss) is our segment's primary measure of profit or loss. The measure of segment assets is reported on the consolidated balance sheets as total consolidated assets. The single segment constitutes all the consolidated entities, and the accompanying consolidated financial statements and the notes to the accompanying consolidated financial statements are representative of such amounts. For the three and six months ended June 30, 2026 and 2025, the Company operates in one operating segment. The table below provides information about the Company’s revenue, significant segment expenses and other segment expenses for the following periods. <table cellpadding="0" cellspacing="0" id="xdx_896_eus-gaap--ScheduleOfSegmentReportingInformationBySegmentTextBlock_zX68rv4edRTi" style="font: 12pt Arial, Helvetica, Sans-Serif;
