Our cybersecurity program is built upon the National Institute for Standards and Technology (“NIST”), International Organization for Standardization (“ISO”) and other best practice frameworks. We employ processes for assessing, identifying, and managing material risks from cybersecurity threats, including engagement of an independent cybersecurity consultant to audit our systems and procedures, make recommendations for improvement and monitor remediation of any identified risks. We also conduct random vulnerability testing including network penetration, phishing and social engineering tests. In addition, we also request Systems and Organization Control (“SOC”) type reports from several of our service providers including our payroll and human resources system provider and stock administration provider. In addition, we provide awareness training to our employees to help identify, avoid and mitigate cybersecurity threats and to remind them of the importance of handling and protecting our information.  Although we develop and maintain systems and controls designed to prevent cybersecurity breaches from occurring, and we have a process to identify and mitigate threats, the development and maintenance of these systems, controls and processes is costly and requires ongoing monitoring and updating as technologies change and efforts to overcome security measures become increasingly sophisticated. Moreover, despite our efforts, the possibility of a breach occurring cannot be eliminated entirely. As we outsource more of our information systems to vendors, engage in more electronic transactions with service customers and vendors, and rely more on cloud-based information systems, the related security risks will increase and we will need to expend additional resources to protect our technology and information systems. <span class="xdx_phnt_RGlzY2xvc3VyZSAtIEN5YmVyc2VjdXJpdHkgUmlzayBNYW5hZ2VtZW50IGFuZCBTdHJhdGVneSBEaXNjbG9zdXJlAA__" id="xdx_908_ecyd--CybersecurityRiskThirdPartyOversightAndIdentificationProcessesFlag_dbT_c20250101__20251231_ztDgannoOoDf">In addition, there can be no assurance that our internal information technology systems or those of our <span class="xdx_phnt_RGlzY2xvc3VyZSAtIEN5YmVyc2VjdXJpdHkgUmlzayBNYW5hZ2VtZW50IGFuZCBTdHJhdGVneSBEaXNjbG9zdXJlAA__" id="xdx_903_ecyd--CybersecurityRiskManagementThirdPartyEngagedFlag_dbT_c20250101__20251231_zuB9MeVUHsFl">third-party contractors, or our consultants’ efforts to implement adequate security and control measures, will be sufficient to protect us against breakdowns, service disruption, data deterioration or loss in the event of a system malfunction, or prevent data from being stolen or corrupted in the event of a cyberattack, security breach, industrial espionage attacks or insider threat attacks which could result in financial, legal, business or reputational harm. <span class="xdx_phnt_RGlzY2xvc3VyZSAtIEN5YmVyc2VjdXJpdHkgUmlzayBNYW5hZ2VtZW50IGFuZCBTdHJhdGVneSBEaXNjbG9zdXJlAA__" id="xdx_903_ecyd--CybersecurityRiskMateriallyAffectedOrReasonablyLikelyToMateriallyAffectRegistrantTextBlock_c20250101__20251231_zAQFculpUhzi">As of the date of this report, we are <span class="xdx_phnt_RGlzY2xvc3VyZSAtIEN5YmVyc2VjdXJpdHkgUmlzayBNYW5hZ2VtZW50IGFuZCBTdHJhdGVneSBEaXNjbG9zdXJlAA__" id="xdx_904_ecyd--CybersecurityRiskMateriallyAffectedOrReasonablyLikelyToMateriallyAffectRegistrantFlag_dbF_c20250101__20251231_zw4Azy9hyE53">not aware of cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition. true true As of the date of this report, we are <span class="xdx_phnt_RGlzY2xvc3VyZSAtIEN5YmVyc2VjdXJpdHkgUmlzayBNYW5hZ2VtZW50IGFuZCBTdHJhdGVneSBEaXNjbG9zdXJlAA__" id="xdx_904_ecyd--CybersecurityRiskMateriallyAffectedOrReasonablyLikelyToMateriallyAffectRegistrantFlag_dbF_c20250101__20251231_zw4Azy9hyE53">not aware of cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition. false Governance. <span class="xdx_phnt_RGlzY2xvc3VyZSAtIEN5YmVyc2VjdXJpdHkgUmlzayBNYW5hZ2VtZW50IGFuZCBTdHJhdGVneSBEaXNjbG9zdXJlAA__" id="xdx_908_ecyd--CybersecurityRiskRoleOfManagementTextBlock_c20250101__20251231_zXcfOoHheQM7">Our senior management team conducts the regular assessment and management of material risks from cybersecurity threats, including review with our IT team and third-party service providers. <span class="xdx_phnt_RGlzY2xvc3VyZSAtIEN5YmVyc2VjdXJpdHkgUmlzayBNYW5hZ2VtZW50IGFuZCBTdHJhdGVneSBEaXNjbG9zdXJlAA__" id="xdx_90E_ecyd--CybersecurityRiskManagementPositionsOrCommitteesResponsibleTextBlock_c20250101__20251231_z8VC87daTO3f">All employees and consultants are directed to report to our senior management any irregular or suspicious activity that could indicate a cybersecurity threat or incident. <span class="xdx_phnt_RGlzY2xvc3VyZSAtIEN5YmVyc2VjdXJpdHkgUmlzayBNYW5hZ2VtZW50IGFuZCBTdHJhdGVneSBEaXNjbG9zdXJlAA__" id="xdx_907_ecyd--CybersecurityRiskBoardCommitteeOrSubcommitteeResponsibleForOversightTextBlock_c20250101__20251231_zk9AQfBRumvl">The <span class="xdx_phnt_RGlzY2xvc3VyZSAtIEN5YmVyc2VjdXJpdHkgUmlzayBNYW5hZ2VtZW50IGFuZCBTdHJhdGVneSBEaXNjbG9zdXJlAA__" id="xdx_90A_ecyd--CybersecurityRiskManagementPositionsOrCommitteesResponsibleFlag_dbT_c20250101__20251231_zFuTS1LQPIN7">Audit Committee of our Board of Directors has a cybersecurity subcommittee which evaluates our cybersecurity assessment and management policies, including quarterly interviews with our senior officers. <span class="xdx_phnt_RGlzY2xvc3VyZSAtIEN5YmVyc2VjdXJpdHkgUmlzayBNYW5hZ2VtZW50IGFuZCBTdHJhdGVneSBEaXNjbG9zdXJlAA__" id="xdx_901_ecyd--CybersecurityRiskProcessForInformingBoardCommitteeOrSubcommitteeResponsibleForOversightTextBlock_c20250101__20251231_zY1VILUUUXP2">Our Audit Committee meets at least quarterly with our independent registered accounting firm and communicates with them regarding any cybersecurity related risks.

On January 12, 2016, the Company changed its name to Atomera Incorporated. Atomera is an early-stage company, having only recently begun limited revenue-generating activities, and is devoting substantially all its efforts toward technology research and development and to commercially licensing its technology to designers and manufacturers of integrated circuits.

<table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 5%">2.</td> <td style="width: 95%; text-align: justify">LIQUIDITY AND MANAGEMENT PLANS</td></tr> </table> At December 31, 2025, the Company had cash and cash equivalents of approximately $19.2 million and working capital of approximately $17.6 million. The Company has generated only limited revenues since inception and has incurred recurring operating losses. Accordingly, it is subject to all the risks inherent in the initial organization, financing, expenditures, and scaling of a new business that is not generating positive cashflow. On May 31, 2022, Atomera entered into an Equity Distribution Agreement with Oppenheimer & Co. Inc. and Craig-Hallum Capital Group LLC (“Craig-Hallum”), as agents, under which the Company offered and sold, from time to time at its sole discretion, shares of its $0.001 par value common stock (“common stock”) in an at the market offering to or through the agents, having aggregate offering proceeds of up to $50.0 million (the “2022 ATM”). The 2022 ATM Facility expired on March 18, 2025. On May 27, 2025, Atomera entered into an Equity Distribution Agreement with Craig-Hallum as agent, under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock in an at-the-market offering to or through the agent, having aggregate offering proceeds of up to $50.0 million (the “2025 ATM”). During the year ended December 31, 2025, the Company sold approximately 1.6 million shares of common stock pursuant to the 2022 ATM and the 2025 ATM at an average price per share of approximately $5.15, resulting in approximately $7.6 million of net proceeds to the Company after deducting commissions and other offering expenses. Based on the funds it has available as of the date of the filing of this report, the Company believes that it has sufficient capital to fund its current business plans and obligations over, at least, 12 months from the date that these financial statements have been issued. The Company’s future capital requirements and the adequacy of its available funds will depend on many factors, including the Company’s ability to successfully commercialize its technology, competing technological and market developments, and the need to enter into collaborations with other companies or acquire technologies to enhance or complement its current offerings. The Company’s operating plans for the next 12 months include increased research and development expenses.

The Company operates as one business segment. Fair Value of Financial Instruments Authoritative guidance requires disclosure of the fair value of financial instruments. The Company’s financial instruments consist of cash and cash equivalents, short-term investments, accounts receivable and accounts payable, the carrying amounts of which approximate their estimated fair values primarily due to the short-term nature of the instruments or based on information obtained from market sources and management estimates. The Company measures the fair value of certain of its financial assets and liabilities on a recurring basis. A fair value hierarchy is used to rank the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value which is not equivalent to cost will be classified and disclosed in one of the following three categories: Level 1 — Quoted prices (unadjusted) in active markets for identical assets and liabilities. Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as unadjusted quoted prices for similar assets and liabilities, unadjusted quoted prices in the markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Cash, Cash Equivalents, and Short-Term Investments The Company considers all highly-liquid investments with an original maturity of three months or less, when purchased, to be cash equivalents. Cash equivalents may be invested in money market funds or U.S. agency bonds. Cash and cash equivalents are carried at cost, which approximates their fair value. The Company's portfolio of short-term investments is comprised solely of U.S. treasury bills and agency bonds with maturities of more than three months, but less than one year. The Company classifies these as available-for-sale at purchase date and will reevaluate such designation at each period end date. The Company may sell these marketable debt securities prior to their stated maturities depending upon changing liquidity requirements. These debt securities are classified as current assets in the balance sheets and recorded at fair value, with unrealized gains or losses included in accumulated other comprehensive income (loss). Gains and losses are recognized when realized. Gains and losses are determined using the specific identification method and are reported in other income, net in the statements of operations when incurred. Unrealized gains and losses are included in other comprehensive income (loss) on the balance sheets. Concentration of Credit Risk and Major Customers Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, short-term investments and accounts receivable.

At times, the amounts on deposit at the financial institution exceed the federally insured limits. Management believes that the financial institution which holds the Company’s cash is financially sound and, accordingly, that minimal credit risk exists. As of December 31, 2025 and 2024, the Company’s cash balances were in excess of insured limits maintained at the financial institution. Accounts Receivable and Unbilled Contracts Receivable The Company grants credit to its business customers. Collateral is generally not required for trade receivables. The Company maintains allowances for potential credit losses when necessary. Trade accounts receivable and unbilled contracts receivable are recorded net of allowances for cash discounts for prompt payment, doubtful accounts, and sales returns. The Company’s policy is to reserve for uncollectible accounts based on its best estimate of the amount of probable credit losses in its existing accounts receivable and unbilled contracts receivable accounts under Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The Company periodically reviews these receivables to determine whether an allowance for doubtful accounts is necessary based on an analysis of past due accounts and other factors that may indicate that the realization of an account may be in doubt. Other factors that the Company considers include its existing contractual obligations, historical payment patterns of its customers and individual customer circumstances, and an analysis of days sales outstanding by customer. Due to the Company’s low volume of customers, management reviews the receivable balances on a customer by customer basis. Account balances deemed to be uncollectible are charged to the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The accounts receivable balance at December 31, 2025 was zero. At December 31, 2024, there were no allowances for doubtful accounts as the Company deemed the balance fully collectible. Impairment of Long-lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that it is more likely than not that the asset’s carrying amount may not be recoverable. The Company conducts its long-lived asset impairment analyses in accordance with authoritative guidance which requires the Company to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals. At December 31, 2025 and 2024, the Company had noted no indicators of impairment. Property and Equipment Items capitalized as property and equipment are stated at cost. Maintenance and routine repairs are charged to operations when incurred, while betterments and renewals are capitalized. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the respective assets starting when the asset is placed in service. Revenue The Company generates revenue from integration engineering services, which it delivers either pursuant to integration license agreements or delivery of engineering services and from the grant of R&D licenses to customers to use its technology in the manufacture of semiconductor wafers and/or devices for the customer’s internal use. Revenue is recognized based on the following steps: (i) identification of the contract, or contracts, with a customer, (ii) identification of the performance obligations in the contract, (iii) determination of the transaction price, (iv) allocation of the transaction price to the performance obligations of the contract, and (v) recognition of revenue when, or as, the Company satisfies a performance obligation. The Company’s integration services generally consist of depositing its proprietary technology onto the customer’s semiconductor wafers and delivering such wafers back to the customer. Revenue from integration services is recognized as the performance obligations are satisfied, which is upon transfer of control of the wafers to the customer (generally upon shipment). Revenue from manufacturing licenses is recognized as the performance obligations are satisfied, which is generally upon delivery of the Company’s MST recipe to the customer but is recognized over time if the performance obligation related to the grant of the license includes customer acceptance. For recognizing integration service revenue from integration license agreements, the Company assesses (i) whether the license grant is distinct from or combined with the transfer of goods or services and (ii) whether the license is a right to access intellectual property or a right to use the intellectual property. For licenses that are not distinct, but combined with other goods or services, the revenue is recognized at a point in time or over time as the obligations to perform the combined services and/or deliver the combined goods are satisfied. The Company’s integration license agreements contain a technology grant as well as a performance obligation to deliver wafers with its technology deposited on them. The Company has determined the grant of rights in these integration license agreements is not distinct from the integration service. Accordingly, revenue from integration license agreements is recognized as the service is provided to the customer. For manufacturing licenses, revenue is recognized at the point in time when the Company delivers its MST recipe because this license confers a right to use the Company’s technology and not a right to access the technology over time. However, in cases where the Company’s grant of a manufacturing license includes a customer acceptance requirement, revenue is recognized over time. The Company’s MSTcad licenses grant customers the right to use MSTcad software to simulate the effects of incorporating MST technology into their semiconductor manufacturing process. Such MSTcad licenses are granted on a monthly basis and revenue is recognized over time. Deferred revenues consist of unearned amounts that have been billed to the customer in advance of the Company’s performance obligations. These amounts have not yet been recognized as revenue. Revenue for these items will be recognized in accordance with the Company’s revenue policy. Research and Development Expenses In accordance with authoritative guidance, the Company charges research and development costs to operations as incurred. Research and development expenses consist of personnel costs for the design, development, testing and enhancement of the Company’s technology, and certain other allocated costs, such as depreciation and other facilities related expenditures. Leases The Company accounts for leases in accordance with ASU No 2016-02, Leases (Topic 842). The Company determines if a contract contains a lease in whole or in part at the inception of the contract. Right-of-use (“ROU”) assets represent its right to use an underlying asset for the lease term while lease liabilities represent its obligation to make lease payments arising from the lease. All leases greater than 12 months result in the recognition of a ROU asset and a liability at the lease commencement date based on the present value of the lease payments over the lease term. Leases are accounted for as operating leases unless it meets one of the following criteria: (a) the lease term accounts for most of the remaining economic life of the underlying asset; (b) the present value of the lease payments is over 90% of the fair value of the underlying asset; (c) the underlying asset would have no alternative use for the lessor at the end of the lease; or (d) ownership of the underlying assets transfers to the Company at the end of the lease term. If the lease meets one of these criteria, then it would be accounted for as financing lease and the ROU assets would be amortized over the life of the lease and interest expense is recognized on the liability. Stock-based Compensation The Company computes stock-based compensation in accordance with authoritative guidance. The Company uses the Black-Scholes-Merton option-pricing model to determine the fair value of its stock options. The Black-Scholes-Merton option-pricing model includes various assumptions, including the fair market value of the common stock of the Company, expected life of stock options, the expected volatility and the expected risk-free interest rate, among others. The fair value for performance-based restricted stock units is fixed at the grant date using a Monte Carlo simulation. These assumptions reflect the Company’s best estimates, but they involve inherent uncertainties based on market conditions generally outside the control of the Company. Forfeitures are recorded when they occur. As a result, if other assumptions had been used, stock-based compensation cost, as determined in accordance with authoritative guidance, could have been materially impacted. Furthermore, if the Company uses different assumptions on future grants, stock-based compensation cost could be materially affected in future periods. Income Taxes In accordance with authoritative guidance, deferred tax assets and liabilities are recorded for temporary differences between the financial reporting and tax bases of assets and liabilities using the current enacted tax rate expected to be in effect when the differences are expected to reverse. A valuation allowance is recorded on deferred tax assets unless realization is considered more likely than not. The Company evaluates its tax positions taken or expected to be taken in the course of preparing the Company’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are not recorded as a tax benefit or expense in the current year. The Company recognizes interest and penalties, if any, related to uncertain tax positions in interest expense. No interest and penalties related to uncertain tax positions were accrued at either December 31, 2025 or 2024. The Company follows authoritative guidance which requires the evaluation of existing tax positions. Management has analyzed all open tax years, as defined by the statute of limitations, for all major jurisdictions, which includes both federal and states where the Company has operations. Open tax years are those that are open for examination by taxing authorities. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates are used when accounting for the fair value of stock-based compensation, borrowing rates used for lease accounting and valuation allowance against deferred tax assets. Actual results could differ from those estimates. Subsequent Events Management has evaluated subsequent events and transactions occurring through the date these financial statements were issued. See Note 15. Adoption of Recent Accounting Standards In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). This new guidance requires entities on an annual basis disclose specific categories in the income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The guidance applies to annual periods beginning after December 15, 2024 on a prospective basis. The Company adopted this ASU on January 1, 2025 and it did not have a material impact on its financial position, results of operations or financial statement disclosure. Recent Accounting Standards In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company does not believe ASU 2024-03 will have a material impact on its financial position, results of operations or financial statement disclosure. In May 2025, the FASB issued ASU 2025-04 Compensation - Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Clarifications to Share-Based Consideration Payable to a Customer (“ASU 2025-04”) which clarifies the guidance on the accounting for share-based payment awards that are granted by an entity as consideration payable to its customer, with the intent to reduce diversity in practice and improve existing guidance by revising the definition of a “performance condition” and eliminating a forfeiture policy election for service conditions associated with share-based consideration payable to a customer. It also clarifies the guidance in Topic 606 on the variable consideration constraint does not apply to share-based consideration payable to a customer “regardless of whether an award’s grant date has occurred”. ASU 2025-04 will be effective for the annual periods beginning after December 15, 2026 with early adoption permitted. The Company does not believe ASU 2025-04 will have a material impact on its financial position, results of operations or financial statement disclosure. In September 2025, the FASB issued ASU 2025-06 Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). The amendments require that an entity capitalize software costs when both: management has authorized and committed to funding the software project; and it is probable that the project will be completed and the software will be used to perform the function intended (referred to as the “probable-to-complete recognition threshold”). In evaluating the probable-to-complete recognition threshold, an entity is required to consider whether there is significant uncertainty associated with the development activities of the software. ASU 2025-06 will be effective for the annual periods beginning after December 15, 2027. The Company does not expect ASU 2025-04 will have a material impact on its financial position, results of operations or financial statement disclosure. In December 2025, the FASB issued ASU 2025-11: Interim Reporting (Topic 270): Narrow-Scope Improvements. The guidance was issued to improve the guidance in Topic 270, Interim Reporting, by improving the navigability of the required interim disclosures and clarifying when that guidance is applicable. The guidance also provides additional guidance on what disclosures should be provided in interim reporting periods. The guidance is effective on a prospective or retrospective basis for financial statements issued for fiscal years beginning after December 15, 2027, and interim reporting periods within fiscal years beginning after December 15, 2028. Early adoption of the guidance is permitted. The Company does not expect ASU 2025-11 will have a material impact on its financial position, results of operations or financial statement disclosure.

Basis of Presentation The financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and reflect the financial position, results of operations and cash flows for all periods presented. The Company operates as one business segment.

Fair Value of Financial Instruments Authoritative guidance requires disclosure of the fair value of financial instruments. The Company’s financial instruments consist of cash and cash equivalents, short-term investments, accounts receivable and accounts payable, the carrying amounts of which approximate their estimated fair values primarily due to the short-term nature of the instruments or based on information obtained from market sources and management estimates. The Company measures the fair value of certain of its financial assets and liabilities on a recurring basis.

Revenue is recognized based on the following steps: (i) identification of the contract, or contracts, with a customer, (ii) identification of the performance obligations in the contract, (iii) determination of the transaction price, (iv) allocation of the transaction price to the performance obligations of the contract, and (v) recognition of revenue when, or as, the Company satisfies a performance obligation. The Company’s integration services generally consist of depositing its proprietary technology onto the customer’s semiconductor wafers and delivering such wafers back to the customer. Revenue from integration services is recognized as the performance obligations are satisfied, which is upon transfer of control of the wafers to the customer (generally upon shipment). Revenue from manufacturing licenses is recognized as the performance obligations are satisfied, which is generally upon delivery of the Company’s MST recipe to the customer but is recognized over time if the performance obligation related to the grant of the license includes customer acceptance. For recognizing integration service revenue from integration license agreements, the Company assesses (i) whether the license grant is distinct from or combined with the transfer of goods or services and (ii) whether the license is a right to access intellectual property or a right to use the intellectual property. For licenses that are not distinct, but combined with other goods or services, the revenue is recognized at a point in time or over time as the obligations to perform the combined services and/or deliver the combined goods are satisfied. The Company’s integration license agreements contain a technology grant as well as a performance obligation to deliver wafers with its technology deposited on them. The Company has determined the grant of rights in these integration license agreements is not distinct from the integration service. Accordingly, revenue from integration license agreements is recognized as the service is provided to the customer. For manufacturing licenses, revenue is recognized at the point in time when the Company delivers its MST recipe because this license confers a right to use the Company’s technology and not a right to access the technology over time. However, in cases where the Company’s grant of a manufacturing license includes a customer acceptance requirement, revenue is recognized over time. The Company’s MSTcad licenses grant customers the right to use MSTcad software to simulate the effects of incorporating MST technology into their semiconductor manufacturing process. Such MSTcad licenses are granted on a monthly basis and revenue is recognized over time. Deferred revenues consist of unearned amounts that have been billed to the customer in advance of the Company’s performance obligations. These amounts have not yet been recognized as revenue. Revenue for these items will be recognized in accordance with the Company’s revenue policy.

Research and Development Expenses In accordance with authoritative guidance, the Company charges research and development costs to operations as incurred. Research and development expenses consist of personnel costs for the design, development, testing and enhancement of the Company’s technology, and certain other allocated costs, such as depreciation and other facilities related expenditures.

Leases The Company accounts for leases in accordance with ASU No 2016-02, Leases (Topic 842). The Company determines if a contract contains a lease in whole or in part at the inception of the contract. Right-of-use (“ROU”) assets represent its right to use an underlying asset for the lease term while lease liabilities represent its obligation to make lease payments arising from the lease. All leases greater than 12 months result in the recognition of a ROU asset and a liability at the lease commencement date based on the present value of the lease payments over the lease term. Leases are accounted for as operating leases unless it meets one of the following criteria: (a) the lease term accounts for most of the remaining economic life of the underlying asset; (b) the present value of the lease payments is over 90% of the fair value of the underlying asset; (c) the underlying asset would have no alternative use for the lessor at the end of the lease; or (d) ownership of the underlying assets transfers to the Company at the end of the lease term. If the lease meets one of these criteria, then it would be accounted for as financing lease and the ROU assets would be amortized over the life of the lease and interest expense is recognized on the liability.

Stock-based Compensation The Company computes stock-based compensation in accordance with authoritative guidance. The Company uses the Black-Scholes-Merton option-pricing model to determine the fair value of its stock options. The Black-Scholes-Merton option-pricing model includes various assumptions, including the fair market value of the common stock of the Company, expected life of stock options, the expected volatility and the expected risk-free interest rate, among others. The fair value for performance-based restricted stock units is fixed at the grant date using a Monte Carlo simulation. These assumptions reflect the Company’s best estimates, but they involve inherent uncertainties based on market conditions generally outside the control of the Company. Forfeitures are recorded when they occur. As a result, if other assumptions had been used, stock-based compensation cost, as determined in accordance with authoritative guidance, could have been materially impacted. Furthermore, if the Company uses different assumptions on future grants, stock-based compensation cost could be materially affected in future periods.

Income Taxes In accordance with authoritative guidance, deferred tax assets and liabilities are recorded for temporary differences between the financial reporting and tax bases of assets and liabilities using the current enacted tax rate expected to be in effect when the differences are expected to reverse. A valuation allowance is recorded on deferred tax assets unless realization is considered more likely than not. The Company evaluates its tax positions taken or expected to be taken in the course of preparing the Company’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are not recorded as a tax benefit or expense in the current year. The Company recognizes interest and penalties, if any, related to uncertain tax positions in interest expense. No interest and penalties related to uncertain tax positions were accrued at either December 31, 2025 or 2024. The Company follows authoritative guidance which requires the evaluation of existing tax positions. Management has analyzed all open tax years, as defined by the statute of limitations, for all major jurisdictions, which includes both federal and states where the Company has operations. Open tax years are those that are open for examination by taxing authorities.

Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates are used when accounting for the fair value of stock-based compensation, borrowing rates used for lease accounting and valuation allowance against deferred tax assets. Actual results could differ from those estimates.

Subsequent Events Management has evaluated subsequent events and transactions occurring through the date these financial statements were issued. See Note 15.

Adoption of Recent Accounting Standards In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). This new guidance requires entities on an annual basis disclose specific categories in the income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The guidance applies to annual periods beginning after December 15, 2024 on a prospective basis. The Company adopted this ASU on January 1, 2025 and it did not have a material impact on its financial position, results of operations or financial statement disclosure.

Recent Accounting Standards In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company does not believe ASU 2024-03 will have a material impact on its financial position, results of operations or financial statement disclosure. In May 2025, the FASB issued ASU 2025-04 Compensation - Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Clarifications to Share-Based Consideration Payable to a Customer (“ASU 2025-04”) which clarifies the guidance on the accounting for share-based payment awards that are granted by an entity as consideration payable to its customer, with the intent to reduce diversity in practice and improve existing guidance by revising the definition of a “performance condition” and eliminating a forfeiture policy election for service conditions associated with share-based consideration payable to a customer. It also clarifies the guidance in Topic 606 on the variable consideration constraint does not apply to share-based consideration payable to a customer “regardless of whether an award’s grant date has occurred”. ASU 2025-04 will be effective for the annual periods beginning after December 15, 2026 with early adoption permitted. The Company does not believe ASU 2025-04 will have a material impact on its financial position, results of operations or financial statement disclosure. In September 2025, the FASB issued ASU 2025-06 Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). The amendments require that an entity capitalize software costs when both: management has authorized and committed to funding the software project; and it is probable that the project will be completed and the software will be used to perform the function intended (referred to as the “probable-to-complete recognition threshold”). In evaluating the probable-to-complete recognition threshold, an entity is required to consider whether there is significant uncertainty associated with the development activities of the software. ASU 2025-06 will be effective for the annual periods beginning after December 15, 2027. The Company does not expect ASU 2025-04 will have a material impact on its financial position, results of operations or financial statement disclosure. In December 2025, the FASB issued ASU 2025-11: Interim Reporting (Topic 270): Narrow-Scope Improvements. The guidance was issued to improve the guidance in Topic 270, Interim Reporting, by improving the navigability of the required interim disclosures and clarifying when that guidance is applicable. The guidance also provides additional guidance on what disclosures should be provided in interim reporting periods. The guidance is effective on a prospective or retrospective basis for financial statements issued for fiscal years beginning after December 15, 2027, and interim reporting periods within fiscal years beginning after December 15, 2028. Early adoption of the guidance is permitted. The Company does not expect ASU 2025-11 will have a material impact on its financial position, results of operations or financial statement disclosure.

Accounts receivable includes amounts billed and currently due from customers. Unbilled contracts receivable represents unbilled amounts expected to be received from customers in future periods, where the revenue recognized to date exceeds the amount billed, and the right to receive payment is subject to the underlying contractual terms. Unbilled contracts receivable amounts may not exceed their net realizable value and are classified as long-term assets if the payments are expected to be received more than one year from the reporting date. The Company had no unbilled contracts receivable as of December 31, 2025. Deferred Revenue The Company records deferred revenue for customers that were issued invoices, but from which the Company has not yet recognized the revenue based on its revenue recognition policy. As of December 31, 2025, the Company has approximately $7,000 in deferred revenue that is expected to be recognized in the next 12 months.

Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the sum of the weighted average number of shares of common stock outstanding and the dilutive common stock equivalent shares outstanding during the period. The Company’s potentially dilutive common stock equivalent shares, which include incremental common shares issuable upon (i) the exercise of outstanding stock options and warrants and (ii) vesting of restricted stock units and restricted stock awards, are only included in the calculation of diluted net loss per share when their effect is dilutive. Since the Company has had net losses for all periods presented, all potentially dilutive securities are anti-dilutive. Accordingly, basic and diluted net loss per share are equal. The following potential common stock equivalents were not included in the calculation of diluted net loss per common share because the inclusion thereof would be anti-dilutive (in thousands): <table cellpadding="0" cellspacing="0" id="xdx_888_eus-gaap--ScheduleOfAntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareTextBlock_pn3n3_zwdp9EVIQ3c7" style="font: 10pt Times New Roman, Times, Serif;

Lease expense for the Company’s operating leases consists of the lease payments recognized on a straight-line basis over the lease term. Expenses for the Company’s financing leases consists of the amortization expenses recognized on a straight-line basis over the lease term and interest expense. The Company’s lease agreement for an epitaxial deposition tool used in the development and marketing of the Company’s technology established a monthly lease payment of $150,000 per month. The lease contains a provision for an annual adjustment of lease payments based on tool availability and usage during the preceding 12 months and the adjusted payment is calculated on August 1 of each year of the lease. Effective August 1, 2023, the lease payments for this tool were adjusted to $137,650 per month for the period August 1, 2023 through July 31, 2024. This adjustment to the lease payments also resulted in a reduction in the ROU and corresponding lease liability. Effective August 1, 2024, the lease payments for this tool were adjusted to $124,071 per month for the period August 1, 2024 through July 31, 2025. This adjustment to the lease payments also resulted in a reduction in the ROU and corresponding lease liability.

In December 2025, the Company entered into a lease agreement for an epitaxial deposition tool in Tempe, Arizona, distinct from the tool previously mentioned. The term of this lease is for 12 months beginning on January 1, 2026 for $95,000 per month. Since the lease term is not for more than one year and there are no extension provisions in the lease, the future lease payments are not included in the lease obligations on the Company’s balance sheets.

The fair value of time-based RSUs is based on the closing price on the day of grant and compensation expenses are recorded on a straight-line method. Awards of performance-based restricted stock units by the Company have a performance period of one, two and three years with the vesting of each award tranche dependent on the Company’s Total Shareholder Return (“TSR”) relative to the TSR of companies in the Russell 2000 Index over that tranche’s performance period. The fair value for performance-based RSUs are fixed at the grant date using a Monte Carlo simulation and the amount of compensation expense is not adjusted during the performance period regardless of changes in the level of TSR achievement. The compensation expense is recognized using the accelerated expense attribution method for each award, which generally equals the vesting term for each performance period.

The Company accounts for income taxes in accordance with ASC 740, which requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company's ability to generate sufficient taxable income within the carryforward period. Because of the Company's recent history of operating losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly, has provided a full valuation allowance. The valuation allowance increased by approximately $4.0 million and $3.6 million during the years ended December 31, 2025 and 2024, respectively.

Under those sections of the Code, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change attributes, such as research tax credits, to offset its post-change income or tax may be limited. In general, an “ownership change” will occur if there is a cumulative change in ownership by “5% stockholders” that exceeds 50 percentage points over a rolling three-year period. The Company rolled forward its Section 382 study through the period ended December 31, 2024. The Company did not trigger an ownership change through this period. Although the Company has not rolled its Section 382 through December 31, 2025, an ownership change during the 2025 is not expected as there have been limited amounts of equity activity. The Company establishes reserves for uncertain tax positions based on the largest amount that is more-likely-than-not to be sustained. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. It is the Company’s policy to recognize interest and penalties related to income tax matters in income tax expense. As of December 31, 2025 and 2024, respectively, the Company has no accrued interest or penalties related to uncertain tax positions. The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions. In the normal course of business, the Company is subject to examination by their respective taxing authorities. The Company is not currently under audit by the Internal Revenue Service or other similar state or local authority. The statute of limitations remains effectively open for all tax years since inception (2007). Tax years outside the normal statute of limitations remain open to examination by tax authorities due to tax attributes generated in earlier years which have been carried forward and may be examined and adjusted in subsequent years when utilized.

Since December 31, 2025, the Company has issued 1.3 million additional shares of common stock through its ATM offering at an average price per share of $2.47 resulting in additional net proceeds of approximately $3.2 million, after deduction of commissions and expenses.
