ATOMERA INCORPORATED

NOTES TO THE UNAUDITED CONDENSED FINANCIAL STATEMENTS

For the Three and Six Months Ended June 30, 2023 and 2022

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 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.

At June 30, 2023, the Company had cash, cash equivalents and short-term investments of approximately $23.8 million and working capital of approximately $21.6 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 financing and scaling of a business that is not generating positive cashflow.

The Company has primarily financed operations through private placements of equity and debt securities, the Company’s Initial Public Offering (the “IPO”) which was consummated on August 10, 2016, and subsequent public offerings of its common stock. On May 31, 2022, Atomera entered into an Equity Distribution Agreement with Oppenheimer & Co. Inc. and Craig-Hallum Capital Group LLC, as agents, 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 “at the market” offerings to or through the agent as its sales agent, having an aggregate offering price of up to $50.0 million (the “ATM Facility”). During the three months ended June 30, 2023, the Company sold approximately 1.4 million shares pursuant to our ATM Facility at an average price per share of approximately $8.15, resulting in approximately $10.8 million of net proceeds to us 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. If the Company is not able to generate sufficient revenue from license fees and royalties in a timeframe that satisfies its cash needs, it will need to raise more capital. In the event it requires additional capital, it will endeavor to acquire additional funds through various financing sources, including the ATM Facility, follow-on equity offerings, debt financing and joint ventures with industry partners. In addition to use of the ATM Facility and other capital raising alternatives, the Company will consider alternatives to our current business plan that may enable it to achieve revenue-producing operations and meaningful commercial success with a smaller amount of capital. If the Company is unable to secure sufficient additional capital, it may be required to curtail our research and development initiatives and take additional measures to reduce costs in order to conserve cash.

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 15, 2023.

Basis of presentation of unaudited condensed financial information

The unaudited condensed financial statements of the Company for the three and six months ended June 30, 2023 and 2022 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 a full fiscal year. The balance sheet information as of December 31, 2022 was derived from the audited financial statements included in the Company's financial statements as of and for the year ended December 31, 2022, included in the Company’s Annual Report on Form 10-K filed with the SEC on February 15, 2023. 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 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 consolidated balance sheet 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 (expense), net in the consolidated statements of operations.

Adoption of recent accounting standards

From time to time, new accounting standards are issued by the Financial Accounting Standards Board (“FASB”) that are adopted by the Company as of the specified effective date. No new accounting standards, issued or effective during the period ended June 30, 2023, have had or are expected to have a significant impact on the Company’s financial statements.

Accounting Standards Codification (“ASC”) 820, Fair Value Measurements (“ASC 820”) 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, is comprised 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 cash equivalents and short-term investments that were measured at fair value on a recurring basis as Level 1 assets.

The Company’s cash, cash equivalents and short-term investments classified by security type as of June 30, 2023 and December 31, 2022 consisted of the following (in thousands):

Interest receivable of approximately $50,000 as of June 30, 2023 includes approximately $8,000 of purchased accrued interest.

The Company recognizes revenue in accordance with Accounting Standards Codification (“ASC”) No. 606. The Company generates revenues from engineering service contracts, license agreements and joint development agreements. 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 when the Company satisfies a performance obligation by transferring the product or service to the customer. When the Company’s performance obligation is the promise to grant a license, revenue is recognized either at a point in time (such as a right to use licensed technology that is under the customer’s control), or over time (typically a right to access technology without obtaining control).

The following table provides information about disaggregated revenue by primary geographical markets and timing of revenue recognition (in thousands):

Unbilled contracts receivable and deferred revenue

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.

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 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):

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, variable lease costs and interest expense. The Company’s lease agreement for a tool used in the development and marketing of the Company’s technology contains a provision for an annual adjustment of lease payments based on tool availability and usage. The potential lease payment adjustment is determined on August 1 of each year of the lease and is calculated based on the tool availability and usage for the preceding 12 months. Effective August 1, 2022, the lease payments for this tool were reduced to $100,824 per month for the period August 1, 2022 through July 31, 2023. This adjustment to the variable lease payments resulted in a reduction in ROU and corresponding lease liability.

Effective May 1, 2023, the Company leased an additional 404 square feet at its Tempe office location under an amendment to its current lease. The monthly rent payment increased from $1,277 per month to $2,365 per month and the increased rent under the amended lease is accounted for as a modification to the lease under ASC 842 at the time of commencement. At the effective date of the lease amendment, a right-of-use asset of approximately $33,000 was recorded along with a short-term operating lease liability of approximately $12,000 and long-term operating lease liability of approximately $21,000. The amended lease ends in February 2026.

In December 2022, the Company entered into a lease agreement for a tool in Tempe, Arizona. The term of this lease is for six months beginning on January 1, 2023 with an option to extend the lease for an additional six months. The initial lease terms were $96,000 per month. In March 2023, the Company elected to extend the lease through December 31, 2023 and in consideration for this extension the remaining lease payments were reduced to $84,000. Since the lease and extension are not for more than one year, the future lease payments are not included in the lease obligations on the Company’s condensed balance sheets.

The Company terminated its office lease in Cambridge, Massachusetts as of March 31, 2023. The cost of the lease was $2,942 per month.

The components of lease costs were as follows (in thousands):

Future minimum payments under non-cancellable leases as of June 30, 2023 were as follows (in thousands):

The below table provides supplemental information and non-cash activity related to the Company’s operating and financing leases are as follows (in thousands):

The table above does not include short-term leases that are one-year or less.

The weighted average remaining discount rate is 5.48% for the Company’s operating leases and 5.25% for the financing lease. The weighted average remaining lease term is 2.6 years for the Company’s operating leases and 3.1 years for the financing lease.

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. The 2017 Plan provides for the issuance of 3,750,000 shares of common stock. As of June 30, 2023, approximately 5,000 shares remain available for issuance. 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 commons stock. All employees and employees of any subsidiary (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 and restricted stock issued under the 2017 Plan and 2023 Plan vest over a period of one to four years from the date of grant.

The following table summarizes the stock-based compensation expense recorded in the Company’s results of operations during the three and six months ended June 30, 2023 and 2022 for stock options and restricted stock granted under the Company’s incentive plans (in thousands):

As of June 30, 2023, there was approximately $8.7 million of total unrecognized compensation expense related to unvested share-based compensation arrangements. This cost is expected to be recognized over a weighted-average period of 2.7 years.

The weighted average grant date fair value per share of the options granted under the Company’s 2017 Plan was $4.95 and $10.60 for the six months ended June 30, 2023 and 2022, respectively. No options were issued in the three months ended June 30, 2023 and 2022 from the Company’s 2017 or 2023 Plan and no options were issued from the Company’s 2023 Plan during the periods presented.

The following table summarizes stock option activity during the six months ended June 30, 2023 (in thousands except exercise prices and contractual terms):

During the six months ended June 30, 2023, the Company granted options under the 2017 Plan to purchase approximately 375,000 shares of its common stock to its employees and consultants. The fair value of these options was approximately $1.9 million at the time of grant.

The Company issues restricted stock to employees, directors and consultants and estimates the fair value based on the closing price on the day of grant. The following table summarizes all restricted stock activity during the six months ended June 30, 2023 (in thousands except per share data):

During the six months ended June 30, 2023, the Company granted approximately 357,000 restricted stock awards under the 2017 Plan and 2023 Plan to its employees and directors. The fair value of these awards was approximately $2.5 million at the time of grant.

Overview

We are engaged in the business of developing, commercializing and licensing proprietary processes and technologies for the $550+ billion semiconductor industry. Our lead technology, named Mears Silicon Technology™, or MST^®, is a thin film of reengineered silicon, typically 100 to 300 angstroms (or approximately 20 to 60 silicon atomic unit cells) thick. MST can be applied as a transistor channel enhancement to CMOS-type transistors, the most widely used transistor type in the semiconductor industry. MST is our proprietary and patent-protected performance enhancement technology that we believe addresses a number of key engineering challenges facing the semiconductor industry. We believe that by incorporating MST, transistors can 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 intend to design or manufacture integrated circuits directly. Instead, we develop and license technologies and processes that we believe offer the designers and manufacturers of integrated circuits a low-cost solution to the industry’s need for greater performance and lower power consumption. Our customers and partners include:

Our commercialization strategy is to generate revenue through licensing arrangements whereby foundries, IDMs and fabless semiconductor manufacturers pay us a license fee for their right to use MST technology in the manufacture of silicon wafers as well as a royalty for each silicon wafer or device that incorporates our MST technology. We also license our MSTcad^TM software to our customers for use in simulating the effects of using MST technology on their wafers and/or devices. To date, we have generated revenue from (i) licensing agreements with two IDMs, one fabless manufacturer and one foundry, (ii) a joint development agreement, or JDA, with a leading semiconductor provider, (iii) engineering services provided to foundries, IDMs and fabless companies and (iv) licensing MSTcad.

In April 2023, we entered into a license agreement with ST Microelectronics (“ST”) that authorizes ST to manufacture and distribute MST-enabled products to its customers. This agreement provides for payment of license fees payable upon reaching milestones consistent with Atomera’s standard business model. Our standard model is based around two major milestones, namely the installation of MST in a customer’s fab and qualification of an MST-enabled process. After process qualification is completed, ST will have the right to commercially distribute MST-enabled products and, assuming ST brings such products to market, we will receive royalties on all MST-enabled products manufactured for commercial purposes. This license agreement with ST is our first grant of commercial manufacturing and distribution rights and, assuming the successful installation of MST and related process qualification, would result in our first revenue from commercial use of MST-enabled products. There can be no assurance, however, that ST will pursue the licensed rights through development to the manufacture and commercial sale of MST-enabled wafers.

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.

On May 31, 2022, we entered into an Equity Distribution Agreement with Oppenheimer & Co. Inc and Craig-Hallum Capital Group LLC, as agents, under which we may offer and sell, from time to time at our sole discretion, shares of our common stock having an aggregate offering price of up to $50.0 million in an “at-the-market” offering or “ATM”, to or through the agents. During the three months ended June 30, 2023, we sold approximately 1.4 million shares pursuant to our ATM at an average price per share of approximately $8.15, resulting in approximately $10.8 million of net proceeds to us after deducting commissions and other offering expenses.

Results of Operations

Revenues. To date, we have only generated limited revenue from customer engagements for integration engineering services, integration license agreements, a manufacturing license granted under a JDA and licensing of MSTcad. Our license agreement with ST, which was executed in April 2023, is our first commercial manufacturing and distribution agreement and, assuming successful completion of contractual milestones and payments of associated fees, will entitle us to royalties on all MST-enabled products manufactured for commercial purposes. Our integration services consist of depositing our MST film on semiconductor wafers, delivering such wafers to customers to finalize building devices, and performing tests for customers evaluating MST. The integration license agreements we have entered into grant the licensees the right to build products that integrate our MST technology deposited by us onto their semiconductor wafers, but the agreements do not grant the licensees the rights to manufacture MST-enabled wafers in their facilities or to sell products incorporating MST. Our JDA included the grant of a manufacturing license to our customer and we were paid for such license upon delivery of our IP transfer package which enabled our customer to install MST in a tool in their facility and to use it to manufacture wafers for internal use. This JDA also contained targeted technical specifications that, if met, would result in payment of a success fee to us. Those technical objectives were met and we have collected the success fee.

For revenue recognition purposes, we have determined that the grant of rights in integration licenses is not distinct from the delivery of integration services, and therefore revenue from both integration licenses and integration services is recognized as the services are provided to the customer. In general, this is proportionate to the delivery of MST processed wafers to the customer, but if the agreements do not specify a time and quantity of wafer delivery, we will record revenue over the period of time in which we anticipate delivering an estimated quantity of wafers. We have also determined that the grant of our manufacturing license under the JDA confers a right to use our technology and accordingly revenue was recognized at the point in time when we delivered our IP transfer package. The success fee under our JDA was treated as engineering services revenue and recognized upon our customer’s confirmation that the JDA’s technical objectives had been met. Our licensing of MSTcad grants 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 basis and revenue is recognized over time.

Revenue was not recorded for the three months ended June 30, 2023 and 2022. Revenue for the six month period ended June 30, 2023 and 2022 was $0 and $375,000, respectively. Our revenue in 2022 consisted of a success fee pursuant to our first JDA and a license fee paid under an integration license agreement.

Cost of revenue. Cost of revenue consists of costs of materials, as well as direct compensation and expenses incurred to provide deliverables that resulted in payment of our success fee and wafers delivered as part of the integration license agreement. Cost of revenue for the six months ended June 30, 2023 and 2022 was $0 and approximately $81,000, 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 engagement. Cost of revenue expenses were not recorded for the three months ended June 30, 2023 and 2022.

Operating expenses. Operating expenses consist of research and development, general and administrative, and selling and marketing expenses. For the three months ended June 30, 2023 and 2022, our operating expenses totaled approximately $5.4 million and $4.4 million, respectively. For the six months ended June 30, 2023 and 2022, our operating expenses totaled approximately $10.5 million and $8.8 million, respectively.

Research and development expense. To date, our operations have focused on the 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 benefit 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 June 30, 2023 and 2022, we incurred approximately $3.2 million and $2.4 million, respectively, of research and development expenses, an increase of approximately $759,000, or 31%. This increase was primarily due to increases of approximately $482,000 in outsourced research and development mainly due to price increases for outsourced foundry services combined with an increase in the number of wafers processed. The increase in research and development expenses also reflected increases of approximately $209,000 in employee-related expenses resulting from new hires, and approximately $78,000 in stock-based compensation costs.

For the six months ended June 30, 2023 and 2022, we incurred approximately $6.2 million and $4.8 million, respectively, of research and development expense, an increase of approximately $1.5 million, or 31%. The increase was primarily due to outsourced research and development of approximately $622,000 due to price increases and increased number of wafers processed. Additional increases were due to approximately $413,000 in employee costs for new hires and approximately $111,000 in wafer purchases to support our research efforts. The price increases by our outsourced foundry service provider will continue to affect our research and development expenses going forward, but the magnitude of the increase seen in the first half of 2023 should not recur in the second half due to the larger number of wafer lot starts as cycle time improved.

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 $1.8 million and $1.7 million for the three months ended June 30, 2023 and 2022, respectively, representing an increase of approximately $108,000, or 6%. The increase is primarily related to an increase in stock-based compensation costs of approximately $71,000 and an increase of approximately $26,000 in IT support services.

General and administrative costs were approximately $3.5 million and $3.3 million for the six months ended June 30, 2023 and 2022, respectively, representing an increase of approximately $202,000, or 6%. The increase is primarily related to an increase in stock-based compensation costs of approximately $167,000 and an increase of approximately $53,000 in IT support services. 

Selling and marketing expense. Selling and marketing expenses consist primarily of salary and benefits for our sales and marketing personnel and business development consulting services. Selling and marketing expenses for the three months ended June 30, 2023 and 2022 were approximately $393,000 and $347,000, respectively, representing an increase of approximately $46,000, or 13%. The increase in costs is primarily related to increased travel and stock-based compensation costs.

Selling and marketing expenses for the six months ended June 30, 2023 and 2022 were approximately $782,000 and $672,000, respectively, representing an increase of approximately $110,000, or 16%. The increase in costs is primarily related to increased travel and stock-based compensation costs.

Interest income. Interest income for three months ended June 30, 2023 and 2022 was approximately $152,000 and $35,000, respectively. Interest income for six months ended June 30, 2023 and 2022 was approximately $351,000 and $38,000, respectively.

Liquidity and Capital Resources

As of June 30, 2023, we had cash and cash equivalents of approximately $12.9 million, short-term investments of approximately $11.0 million and working capital of approximately $21.6 million. For six months ended June 30, 2023, we had a net loss of approximately $10.2 million and used approximately $8.2 million of cash and cash equivalents in operations. Since inception, we have incurred recurring operating losses.

During the six months ended June 30, 2023, we sold approximately 1.4 million shares pursuant to our ATM at an average price per share of approximately $8.09, resulting in approximately $11.1 million of net proceeds to us after deducting commissions and other offering expenses. Since June 30, 2023 we have issued approximately 24,000 additional shares through our ATM offering at an average price per share of $9.17 resulting in additional net proceeds of approximately $214,000.

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 Facility, 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.
