Atomera Incorporated

Notes to the Unaudited Condensed Financial Statements

For the Three and Nine Months Ended September 30, 2026 and 2025

1. NATURE OF OPERATIONS

Atomera Incorporated (“Atomera” or the “Company”) was incorporated in the state of Delaware in March 2007 under the name MEARS Technologies, Inc. and is engaged in the development, commercialization and licensing of proprietary processes and technologies for the semiconductor industry. On January 12, 2016, the Company changed its name to Atomera Incorporated.

Atomera is an early-stage company, having generated only limited revenue, 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.

2. LIQUIDITY AND MANAGEMENT PLANS

At September 30, 2026, the Company had cash, cash equivalents and short-term investments of approximately $34.8 million and working capital of approximately $30.6 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 in an at the market offering to or through the agents, having aggregate offering proceeds of approximately $44.8 million (the “2022 ATM”). The 2022 ATM 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 $0.001 par value 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 nine months ended September 30, 2026, the Company sold approximately 1.3 million shares of common stock pursuant to the 2025 ATM at an average price per share of approximately $2.47 resulting in approximately $3.1 million in net proceeds to the Company after deducting commissions and other offering expenses. The Company did not sell any shares of common stock pursuant to the 2025 ATM during the three months ended September 30, 2026.

On February 24, 2026, the Company completed a registered direct offering (the “Offering”) of 5,000,000 shares of its $0.001 par value common stock at a purchase price of $5.00 per share pursuant to a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional investors. In connection with the Offering, the Company entered into a placement agent agreement with Craig-Hallum, pursuant to which Craig-Hallum served as the exclusive placement agent for the issuance and sale of securities of the Company pursuant to the Purchase Agreement. As compensation for such placement agent services, the Company paid Craig-Hallum an aggregate cash fee equal to 5.0% of the gross proceeds received by the Company from the Offering and agreed to reimburse up to $75,000 of legal and other expenses actually incurred. Net proceeds to the Company after deducting the placement agent fee and expenses were approximately $23.6 million.

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.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Significant Accounting Policies

There have been no material changes in the Company’s significant accounting policies to those previously disclosed in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 24, 2026.

Basis of Presentation of Unaudited Condensed Financial Information

The unaudited condensed financial statements of the Company for the three and nine months ended September 30, 2026 and 2025 have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. However, such information reflects all adjustments (consisting solely of normal recurring adjustments) which are, in the opinion of management, necessary for the fair presentation of the Company’s financial position and its results of operations. Results shown for interim periods are not necessarily indicative of the results to be obtained for the full fiscal year. The balance sheet information as of December 31, 2025 was derived from the audited financial statements included in the Company’s financial statements as of and for the year ended December 31, 2025, included in the Company’s Annual Report on Form 10-K filed with the SEC on February 24, 2026. These unaudited condensed financial statements should be read in conjunction with that report.

Cash, Cash Equivalents, and Short-Term Investments

The Company considers all highly-liquid investments with an original maturity date of three months or less, when purchased, to be cash equivalents. Cash equivalents may be invested in money market funds, treasury bills or U.S. government agency bonds. Cash and cash equivalents are carried at cost, which approximates their fair value.

The Company may also purchase short-term investments comprised of U.S. treasury bills and U.S. government agency bonds with maturities of more than three months, but less than one year. The Company classifies these as available-for-sale at their 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 condensed 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 condensed statements of operations when incurred. Unrealized gains and losses are included in other comprehensive income (loss) on the condensed balance sheets.

Recent Accounting Standards

In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-03 (as clarified by ASU 2025-01 in January 2025), 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 annual reporting periods beginning after December 15, 2026, and for interim periods within annual reporting 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.

9

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 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. 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 believe ASU 2025-06 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 to improve the navigability of the interim reporting guidance in ASC 270 and clarify when it applies. For public business entities, the amendments in this update are effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company does not believe ASU 2025-11 will have a material impact on its financial position, results of operations or financial statement disclosure.

4. FAIR VALUE MEASUREMENTS

Accounting Standards Codification (“ASC”) 820, Fair Value Measurements states that fair value represents the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. The three-tiered fair value hierarchy, which prioritizes which inputs should be used in measuring fair value, consists of:

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.

The Company’s Money Market Funds and U.S. Treasury securities are valued using quoted prices in active markets and are classified as Level 1. The Company’s U.S. government agency securities are valued using prices obtained from a third-party pricing service, which uses observable market inputs such as benchmark yields, reported trades and quoted prices for similar securities, and are classified as Level 2.

10

The Company’s cash, cash equivalents and short-term investments classified by security type as of September 30, 2026 and December 31, 2025 consisted of the following (in thousands):

September 30, 2026
Cost Unrealized Gain/(Loss) Accretion of Discount Fair Value
Cash $316 $ – $ – $316

Cash $279 $ – $ – $279
Money Market Funds 18,931 – – 18,931
Total $19,210 $– $– $19,210

5. REVENUE

The Company recognizes revenue in accordance with ASC 606. The amount of revenue that the Company recognizes reflects the consideration it expects to receive in exchange for goods or services and such revenue is recognized at the time when goods or services are transferred and/or delivered to its customers. Revenue is recognized when the Company satisfies a performance obligation by transferring the product or service to the customer, either at a point in time or over time. Revenue from MSTcad licenses is recognized over a period of time.

Unbilled contracts receivable

Timing of revenue recognition may differ from the timing of invoicing customers. 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 September 30, 2026.

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 September 30, 2026, the Company had no deferred revenue.

6. BASIC AND DILUTED LOSS PER SHARE

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of shares outstanding for the period. 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 (ii) vesting of restricted stock units and (iii) 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):

The Company accounts for leases over one year under ASC 842. 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 a 300mm 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, 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 right-of-use (“ROU”) asset and corresponding lease liability. Effective August 1, 2025, the lease payments for this tool were adjusted to $133,125 per month for the period August 1, 2025 through April 30, 2026. The final three months of the lease were prepaid at the commencement of the lease. This adjustment to the lease payments also resulted in a reduction in the ROU asset and corresponding lease liability. In August 2026, the lease was extended for an additional three months through October 2026 at a rate of $250,000 per month. Due to the modification, an additional ROU and lease liability of approximately $590,000 was recorded during the three months ended September 30, 2026. The lease liability is based on the present value of the minimum lease payments, discounted using an estimated incremental borrowing rate of 8.75%.

In December 2025, the Company and its landlord amended the lease of the corporate headquarters in Los Gatos, California. The amendment extends the expiration date of the lease from January 2026 to March 2031. An additional ROU asset and lease liability of approximately $856,000 was recorded during the year ended December 31, 2025. The lease liability is based on the present value of the minimum lease payments, discounted using an estimated incremental borrowing rate of 8.75%. The lease contains escalating payments on the anniversary of the original commencement of the lease which are included in the measurement of the lease liability. Additional payments based on a change in the Company’s share of the operating expenses, including property taxes and insurance are recorded as a period expense when incurred.

In February 2026, the Company and its landlord amended the lease of its Tempe office location. The lease also contains a performance standard for research collaboration with Arizona State University. The agreement requires a minimum value of collaboration in each year of the lease. The lease is accounted for under ASC 842 and accordingly, the research payments are included in the ROU and lease liability. The lease is for three years with an option to extend the lease for an additional two years. The lease liability is based on the present value of the minimum lease payments, discounted using an estimated incremental borrowing rate of 8.75%. An ROU asset and lease liability of approximately $342,000 was recorded during the nine months ended September 30, 2026.

In December 2025, the Company entered into a lease agreement for a 200mm 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. At inception, the lease term was not for more than one year and there were no extension provisions in the lease, and therefore, the future lease payments were not included in the lease obligations on the Company’s condensed balance sheets. In September 2026, the Company agreed to extend the lease through December 31, 2027. The lease included a lump sum payment of approximately $1.4 million due and paid on October 1, 2026 for all of 2027. Lease payments for October 2026 through December 2026 remained at $95,000 per month. At the time of the modification, the Company recorded an ROU asset and current lease liability of approximately $1.7 million. The lease liability is based on the present value of the minimum lease payments, discounted using an estimated incremental borrowing rate of 8.75%.

8. STOCK-BASED COMPENSATION

In May 2017, the Company’s shareholders approved its 2017 Stock Incentive Plan (“2017 Plan”) after its 2007 Stock Incentive Plan (“2007 Plan”) had expired in March 2017. The 2017 Plan provides for the grant of non-qualified stock options and incentive stock options to purchase shares of the Company’s common stock and for the grant of restricted and unrestricted shares of common stock and restricted stock units. The 2017 Plan provides for the issuance of 3,750,000 shares of common stock. In May 2023, the Company’s shareholders approved its 2023 Stock Incentive Plan (“2023 Plan”). The 2023 plan provides for the issuance of 2,000,000 shares of common stock. In May 2025, the Company’s shareholders approved an amendment to the 2023 Plan, adding an additional 1,750,000 shares to this plan. All employees (including officers and directors who are also employees), as well as all of the nonemployee directors and other consultants, advisors and other persons who provide services to the Company are eligible to receive incentive awards under the 2017 Plan and 2023 Plan. Generally, stock options, restricted stock and restricted stock units issued under the 2017 Plan and 2023 Plan vest over a period of one to four years from the date of grant. As of September 30, 2026, a total of approximately 725,000 shares remain available for issuance under the plans.

The intrinsic value is based on the Company’s closing stock price of $4.36 on September 30, 2026.

16

Performance-based Stock Options:

In March 2026, the Company began issuing performance-based stock options (“PSOs”) to certain employees. The PSOs include both time-based and stock-price-based vesting thresholds, with 25% of the PSO time-vesting one year after the grant date and the remaining PSOs time-vesting over the next three years, but the PSOs only vest and become exercisable if the volume-weighted average price of the Company’s common stock as quoted on the Nasdaq Stock Market over any 30 consecutive trading days during the five-year period from the date of grant exceeds the stock-price hurdles specified in the PSO awards. The stock-price hurdles for PSOs granted were $7.50, $12.50 and $20.00. The fair value of these PSOs was estimated using a Monte Carlo simulation and the stock compensation expense is amortized over the requisite service period for each tranche, which is the longer of the derived service period or the explicit service period. Approximately 184,000 options achieved the performance criteria and will begin vesting one year after the grant date. The average grant date fair value was determined to be $3.87 on the day of grant.

Restricted Stock Units:

The Company issues restricted stock units (“RSUs”) to employees, directors and consultants and a portion of the RSUs issued are subject to time-based vesting and a portion are subject to performance-based vesting criteria. The fair value of time-based RSUs is based on the closing price on the day of grant and they vest over zero to four years. Awards of performance-based restricted stock units by the Company have a performance period of one, two or 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 awards is 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.

Overview

We are engaged in the business of developing, commercializing and licensing proprietary processes and technologies for the $700+ billion semiconductor industry. Our lead technology, named Mears Silicon Technology™, or MST®, is a thin film of reengineered silicon. MST is our proprietary and patent-protected transistor enhancement technology that we believe addresses a number of key engineering challenges facing the semiconductor industry. MST provides multiple benefits to the semiconductor manufacturing process, enabling transistors to be made smaller, with increased speed, reliability and power efficiency. In addition, since MST is an additive and low-cost technology, we believe it can be deployed on an industrial scale, with machines commonly used in semiconductor manufacturing. We believe that MST can be widely incorporated into the most common types of semiconductor products, including analog, logic, optical and memory integrated circuits.

We do not design or manufacture wafers or integrated circuits directly. Instead, we develop and license technologies and processes that we believe offer the designers and manufacturers of wafers and integrated circuits a low-cost solution to the industry’s need for greater performance and lower power consumption. Our customers and partners include:

· foundries, which manufacture integrated circuits on behalf of fabless manufacturers;
· integrated device manufacturers, or IDMs, which are the fully-integrated designers and manufacturers of integrated circuits;
·

fabless semiconductor manufacturers, which are designers of integrated circuits that outsource the manufacturing of their chips to foundries;

· manufacturers of semiconductor wafers, which provide the substrates upon which integrated circuits are fabricated;
· original equipment manufacturers, or OEMs, that manufacture the epitaxial, or epi, machines used to deposit semiconductor layers, such as the MST film, onto silicon wafers; and
· electronic design automation companies, which make tools used throughout the industry to simulate performance of semiconductor products using different materials, design structures and process technologies.
20

Our principal business objective is to enter into commercial license agreements that enable our customers to manufacture and sell MST-enabled products, generating license revenues and ongoing royalties. We also license our MSTcad® software to customers, enabling them to simulate the effects of MST on their products using Synopsys, Inc.’s technology computer-aided design, or TCAD, software. In addition, we offer fee-based integration engineering services to customers to evaluate the effects of MST as integrated into their manufacturing flow. Typically, we offer these services through paid evaluation arrangements, joint development agreements (“JDAs”) or integration license agreements.

Our goal is that MSTcad licensing and engineering service arrangements will be tools that demonstrate the benefits of MST when integrated into customers’ manufacturing processes and will lead customers to enter into commercial license agreements. A “commercial license” consists of (i) an R&D license, which grants our customer the rights to install MST on a tool in their fab and to manufacture MST-enabled products, but only for internal use and limited customer sampling and (ii) a high-volume manufacturing, or HVM, license which grants the rights to manufacture and sell MST-enabled products to their customers.

Depending upon our customers’ business needs and how we initially engaged with them, we may make these license grants in one or more separate contracts. Our preferred model is to charge our customers upfront license fees for each license grant. Under our licensing model, the R&D license fee is due upon installation of MST in a tool at our customer’s fab and a larger HVM license fee will be due when our customer completes qualification of MST in their process and before they can sell MST -enabled products to their customers. Upon the grant of an HVM license, our licensees are also required to make royalty payments to us based on the number and/or sales price of MST-enabled products they sell. We have engaged with certain customers under joint development agreements, or JDAs. Our JDAs include development, technology transfer, manufacturing and licensing components.

To date, applications of our MST technology have primarily been for power devices, RFSOI devices and advanced CMOS integrated circuits including logic and memory. CMOS integrated circuits are the most widely used type of integrated circuits in the semiconductor industry. We believe MST has the potential to overcome the key challenges found in the implementation of next-generation nano-scale semiconductor devices incorporating CMOS-type transistors, namely enhancing drive current, reducing leakage and reducing variability. In addition, we believe that MST has the potential to deliver these benefits through a single technology that requires relatively minor modifications to the industry-standard CMOS manufacturing flow. Consequently, we believe that by incorporating MST, designers can make transistors with increased speed, reliability and energy efficiency, without significantly altering the current fabrication process or cost of production.

Starting in 2024, we began applying our technology to wafers used for fabrication of “compound semiconductors” which are devices built using materials other than silicon, such as gallium nitride (GaN), which have properties especially attractive to the power and radio frequency markets. Currently, materials such as GaN suffer from a tradeoff between high-cost specialized wafers and defective, low-yielding wafers resulting from the crystal lattice mismatch between heterogeneous materials. We believe MST can offer a cost-effective solution to these tradeoffs by serving as a buffer layer between different materials, such as between GaN and a silicon wafer substrate.

We were organized as a Delaware limited liability company under the name Nanovis LLC on November 26, 2001. On March 13, 2007, we converted to a Delaware corporation under the name Mears Technologies, Inc. On January 12, 2016, we changed our name to Atomera Incorporated. Shares of our common stock are listed on the NASDAQ Capital Market under the symbol “ATOM”.

On May 31, 2022, we entered into an Equity Distribution Agreement with Oppenheimer & Co. Inc. and Craig-Hallum Capital Group LLC (“Craig-Hallum”), as agents, under which we offered and sold, from time to time at our sole discretion, shares of our 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 expired on March 18, 2025.

21

On May 27, 2025, we entered into an Equity Distribution Agreement with Craig-Hallum as agent, under which we may offer and sell, from time to time at our sole discretion, shares of our common stock in an “at-the-market” offering, (the “2025 ATM”) to or through the agent, having aggregate offering proceeds of up to $50.0 million. During the three months ended September 30, 2026, no shares were sold pursuant to the 2025 ATM. During the nine months ended September 30, 2026, approximately 1.3 million shares were sold pursuant to the 2025 ATM at an average price per share of approximately $2.47 resulting in approximately $3.1 million of net proceeds to us after deducting commissions and other offering expenses.

On February 24, 2026, we completed a registered direct offering (the “Offering”) of 5,000,000 shares of our common stock at a purchase price of $5.00 per share pursuant to a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional investors. In connection with the Offering, the Company entered into a placement agent agreement with Craig-Hallum, pursuant to which Craig-Hallum served as the exclusive placement agent for the issuance and sale of securities of the Company pursuant to the Purchase Agreement. As compensation for such placement agent services, the Company paid Craig-Hallum an aggregate cash fee equal to 5.0% of the gross proceeds received by the Company from the Offering and agreed to reimburse up to $75,000 of legal and other expenses actually incurred. Net proceeds to the Company after deducting the placement agent fee and expenses were approximately $23.6 million.

Results of Operations

Revenues. To date, we have generated only limited revenue from customer engagements for engineering services, integration license agreements, R&D licenses granted under a JDA and under our license agreement with ST Microelectronics and from licensing of MSTcad. Our MSTcad licenses grant customers the right to use MSTcad software to simulate the effects of incorporating MST technology into their semiconductor manufacturing process. MSTcad licenses are granted on a monthly or yearly basis and revenue is recognized over time.

Revenue for the three and nine months ended September 30, 2026 was approximately $0 and $169,000, respectively. Revenue consisted of engineering services revenue from the delivery of MST wafers. Revenue for the three and nine months ended September 30, 2025 of approximately $11,000 and $15,000 and consisted of MSTcad licensing and delivery of MST wafers.

Cost of revenue. Cost of revenue consists of costs of materials, as well as direct compensation and expenses incurred to deliver wafers and perform services, and consulting services provided for our MSTcad licenses. Cost of revenue for the three and nine months ended September 30, 2026 was approximately $0 and $152,000, respectively. Cost of revenue for the three and nine months ended September 30, 2025 was approximately $128,000 and $190,000, respectively. We anticipate that our cost of revenue will vary substantially depending on the mix of license and engineering services revenues we receive and the nature of products and/or services delivered in each customer’s engagement. Cost of revenue is expensed when incurred and may not correspond with revenue earned in the same period.

Operating expenses. Operating expenses consist of research and development, general and administrative, and selling and marketing expenses. For the three months ended September 30, 2026 and 2025, our operating expenses totaled approximately $6.3 million and $5.7 million, respectively. For the nine months ended September 30, 2026 and 2025, our operating expenses totaled approximately $19.4 million and $16.3 million, respectively.

Research and development expense. To date, our operations have focused on research, development, patent prosecution, and commercialization of our MST technology and related technologies such as MSTcad. Our research and development costs primarily consist of payroll and benefits costs for our engineering staff and costs of outsourced fabrication (including epi tool leases) and metrology of semiconductor wafers incorporating our MST technology.

For the three months ended September 30, 2026 and 2025, we incurred approximately $3.6 million and $3.3 million, respectively, of research and development expenses, an increase of approximately $343,000, or 10%. This increase was primarily due to an approximately $325,000 increase in tool lease costs under the lease extension for our 300mm epitaxial deposition tools in August 2026.

22

The lease extension that resulted in these increased costs runs through October 31, 2026 and negotiations for continued usage of this tool or a similar one are ongoing so future tool usage costs may be higher or lower than the rates under our past lease and the related extension.

For the nine months ended September 30, 2026 and 2025, we incurred approximately $10.4 million and $9.6 million, respectively, of research and development expenses, an increase of approximately $828,000, or 9%. This increase is primarily related to an increase in tool related costs of approximately $524,000, which consisted of increased costs for the amended tool lease in August 2026 and a cancellation fee relating to a planned purchase of a lab infrastructure tool. Additionally, there were increases in stock-based compensation of approximately $267,000, and an increase in accrued bonus expense of approximately $137,000.

General and administrative expense. General and administrative expenses consist primarily of payroll and benefit costs for administrative personnel, office-related costs and professional fees. General and administrative costs were approximately $2.3 million and $2.2 million for the three months ended September 30, 2026 and 2025, respectively, representing an increase of approximately $173,000, or 8%. The increase is primarily related to increases in stock-based compensation expenses of approximately $239,000 and increase of approximately $86,000 in legal costs and filing fees related to our patent portfolio. These increases were partially offset by a decrease in employee related costs of approximately $139,000, mainly related to a reduction in our bonus accrual.

For the nine months ended September 30, 2026 and 2025, general and administrative costs were approximately $7.8 million and $6.3 million, respectively, representing an increase of approximately $1.5 million, or 24%. The increase is primarily related to increases of approximately $505,000 in bonus accrual, stock-based compensation expenses of approximately $766,000 and an increase in legal costs and filing fees related to our patent portfolio of approximately $262,000.

We believe that our available working capital is sufficient to fund our presently forecasted working capital requirements for, at least, the next 12 months following the date of the filing of this report. However, our future capital requirements and the adequacy of our available funds will depend on many factors, including our ability to successfully commercialize our MST technology, competing technological and market developments, and the need to enter into collaborations with other companies or acquire technologies to enhance or complement our current offerings. If we are not able to generate sufficient revenue from license fees and royalties in a timeframe that satisfies our cash needs, we will need to raise more capital. In the event we require additional capital, we will endeavor to acquire additional funds through various financing sources, including our ATM, follow-on equity offerings, debt financing and joint ventures with industry partners. In addition, we will consider alternatives to our current business plan that may enable us to achieve revenue-producing operations and meaningful commercial success with a smaller amount of capital. If we are unable to secure additional capital, we may be required to curtail our research and development initiatives and take additional measures to reduce costs in order to conserve cash.
