Atomera Inc (ATOM) is a semiconductor materials and technology licensing company that has been making significant strides in advancing its proprietary Mears Silicon Technology (MST) across multiple high-growth market segments. With a focus on enabling semiconductor designers and manufacturers to overcome key engineering challenges, Atomera has positioned itself as a technological pioneer in an industry undergoing rapid transformation.
Company Background
Established in 2001 and headquartered in Los Gatos, California, Atomera has a rich history of innovation and development. The company was originally incorporated in the state of Delaware in March 2007 under the name MEARS Technologies, Inc., focusing on the development and commercialization of proprietary processes and technologies for the semiconductor industry. In January 2016, the company changed its name to Atomera Incorporated, reflecting its commitment to commercializing its proprietary MST technology.
As an early-stage company, Atomera has only recently begun limited revenue-generating activities. The company has devoted substantially all of its efforts towards technology research and development and commercially licensing its technology to designers and manufacturers of integrated circuits. To date, Atomera has generated limited revenue from customer engagements for engineering services, integration license agreements, an R&D license granted under a joint development agreement, and licensing of its MSTcad software.
Throughout its history, Atomera has faced challenges typical of an early-stage technology company. The company has incurred recurring operating losses and has had to carefully manage its cash resources. Atomera has also had to navigate the long and complex sales cycles inherent in the semiconductor industry as it works to commercialize its MST technology with potential customers.
Technology and Business Model
Atomera's flagship technology, MST, is a thin film of reengineered silicon that typically ranges from 100 to 300 angstroms in thickness, or approximately 20 to 60 silicon atomic unit cells. This patented and proprietary performance enhancement technology is designed to address several key engineering challenges faced by the semiconductor industry, including the ability to make transistors smaller, faster, more reliable, and more power-efficient.
One of the key strengths of Atomera's business model is its focus on licensing its technology to semiconductor designers and manufacturers, rather than engaging in the capital-intensive process of chip fabrication. This approach has allowed the company to concentrate its resources on research, development, and commercialization of its MST technology, while leveraging the expertise and infrastructure of its industry partners.
Atomera's commercialization strategy is centered on generating revenue through licensing arrangements where foundries, integrated device manufacturers (IDMs), and fabless semiconductor manufacturers pay licensing fees for the right to use MST technology in the manufacture of silicon wafers, as well as royalties for each wafer or device that incorporates the MST technology.
The company has entered into several types of licensing agreements with customers, including integration license agreements, a joint development agreement (JDA), and its first full commercial manufacturing and distribution license agreement with STMicroelectronics (ST). The integration license agreements grant customers the right to build products that integrate Atomera's MST technology, but do not include the rights to manufacture or sell those products commercially. The JDA with a leading semiconductor provider included the grant of an R&D license, which allowed the customer to install MST in one of their fabrication tools and use it to manufacture wafers for internal use.
In April 2023, Atomera entered into its first full commercial license agreement with ST. This agreement grants ST the rights to manufacture and distribute MST-enabled products to its customers. The license agreement includes upfront milestone payments as well as ongoing royalties to Atomera based on ST's sales of MST-enabled products.
Financials
Atomera's financial performance has been characterized by limited revenue to date, as the company has been primarily focused on technology development, customer engagement, and laying the groundwork for future commercialization. For the fiscal year ended December 31, 2024, the company reported revenue of $135,000, a significant decline from the $550,000 reported in the previous year. This decrease in revenue was primarily due to the company's shift in focus towards securing additional licensing agreements and advancing its technology integration with key customers.
Despite the limited revenue, Atomera has been able to maintain a strong financial position, with a balance of cash, cash equivalents, and short-term investments of $26.8 million as of December 31, 2024, compared to $19.5 million at the end of 2023. This liquidity has been bolstered by the company's successful at-the-market (ATM) equity offering, which raised approximately $21.3 million in net proceeds during 2024.
In terms of operating performance, Atomera reported a GAAP net loss of $18.4 million, or $0.68 per share, for the fiscal year 2024, compared to a net loss of $19.8 million, or $0.80 per share, in the previous year. The decrease in net loss was driven by a $1.9 million reduction in operating expenses, primarily due to a decline in research and development (R&D) costs.
Atomera's research and development efforts have been a key focus, with the company investing $11.0 million in R&D during 2024, down from $12.5 million in the prior year. This decrease was largely attributable to a reduction in outsourced engineering services following the closure of TSI Semiconductor's operations, which had previously provided some of Atomera's foundry services.
The company's cash flow performance has also been a point of emphasis, with Atomera reporting cash used in operating activities of $13.2 million in 2024, compared to $14.6 million in 2023. This improvement in cash flow was driven by the company's ongoing efforts to manage its expenses and optimize its operations. The annual free cash flow for 2024 was -$13.25 million.
For the most recent quarter (Q4 2024), Atomera reported revenue of $23,000, a significant decrease from $550,000 in Q4 2023. This 95.8% year-over-year decrease was due to the company recognizing a large manufacturing license fee in Q4 2023 that did not recur in Q4 2024. The net loss for Q4 2024 was $4.66 million.
Liquidity
Atomera's liquidity position remains strong, with a debt-to-equity ratio of 0.08 as of December 31, 2024. The company's current ratio and quick ratio both stand at 7.58, indicating a robust ability to meet short-term obligations. As mentioned earlier, Atomera had $26.8 million in cash, cash equivalents, and short-term investments at the end of 2024. The company does not have any disclosed available credit lines.
Recent Developments and Market Opportunities
One of the critical developments for Atomera in recent years has been its progress towards commercialization with its lead customer, ST Microelectronics (STM). In April 2023, the company announced its first full commercial license agreement with STM, which granted the semiconductor manufacturer the rights to manufacture and distribute MST-enabled products. This was a significant milestone for Atomera, as it was the first time the company granted such broad commercial rights to a customer. Prior to this, Atomera had entered into various integration license agreements and joint development agreements with other customers, but those did not confer the same level of manufacturing and distribution rights. While the timeline for this engagement has faced some delays, Atomera remains optimistic about its potential to reach the next milestone of process qualification, which could lead to the start of production and the recognition of royalty-based revenue.
Atomera has also been actively expanding its technology offerings and customer engagements across several high-growth market segments, including advanced logic, memory, radio frequency silicon-on-insulator (RF-SOI), power semiconductors, and emerging opportunities in gallium nitride (GaN) materials. The company's MST technology has demonstrated the potential to address key challenges in these areas, such as enhancing transistor performance, reducing power consumption, and improving manufacturing yields.
In the advanced logic and memory segments, Atomera has highlighted the growing importance of materials engineering, particularly in the context of the industry's shift towards gate-all-around transistor architectures at the 2-nanometer node and below. The company believes its MST technology can be readily integrated into these advanced manufacturing processes, providing a compelling solution to overcome performance and power-related obstacles.
Within the RF-SOI market, Atomera has continued to work with the majority of device manufacturers leveraging this substrate technology, offering performance advantages that the company believes are not possible without its MST innovation. In the power semiconductor space, the company's MST-SP and MST-SPX products have been attracting interest from a wide range of players, driven by the growing demand for efficient power management solutions in areas such as artificial intelligence, data centers, and vehicle electrification.
More recently, Atomera has made inroads into the rapidly expanding gallium nitride (GaN) market, which is projected to grow at a compound annual rate of over 26% to reach $12 billion in the next five years. The company's collaboration with Sandia National Laboratories' Center for Integrated Nanotechnologies (CINT) aims to validate the effectiveness of its MST technology in addressing key manufacturing challenges associated with GaN-on-silicon devices, which could open up a new avenue for revenue generation.

Atomera's patent portfolio is a crucial asset for the company, containing 108 U.S. patents and 112 foreign patents as of December 31, 2024, with 50 pending U.S. patent applications and 77 pending foreign patent applications. The company relies on both its patent portfolio as well as trade secret protections for its technology, underscoring the importance of intellectual property in its business model.
In terms of human capital, Atomera has 20 full-time employees as of the date of this report. This lean workforce allows the company to maintain a focused approach to its research and development efforts while keeping operational costs in check.
Outlook and Conclusion
Despite the challenges and delays encountered in some of its customer engagements, Atomera remains optimistic about its long-term growth prospects. The company's diverse portfolio of market opportunities, expanding patent portfolio, and strengthened financial position provide a solid foundation for continued innovation and commercialization efforts.
Looking ahead to 2025, Atomera expects its non-GAAP operating expenses to be in the range of $17 million to $18 million, consistent with 2023 levels. The company has not provided specific revenue guidance beyond Q1 2025, stating that it does not expect to recognize any revenue in that quarter. The next major revenue milestone under Atomera's agreement with ST Microelectronics will occur when ST enters formal process qualification, which typically takes about 9 months before production starts.
As Atomera navigates the complexities of the semiconductor industry, the company's ability to successfully execute its licensing strategy, secure additional commercial agreements, and capitalize on emerging market trends will be crucial in determining its future success. Investors will likely keep a close eye on the company's progress in transitioning its customer relationships from the integration and development phases to high-volume manufacturing and royalty-bearing revenue streams.
