For the fiscal year ended December 31, 2025, Ascent Solar Technologies reported total revenue of $76,773 9, all of which was derived from product sales 10. The cost of revenue for the period was $196,332 11. Research, development, and manufacturing operations costs amounted to $2,443,194 12, while selling, general, and administrative expenses were $4,098,004 13. Share-based compensation expense was $1,133,963 14, and depreciation and amortization totaled $79,661 15. The company reported a net loss of $7,832,755 16 and a diluted EPS of $(3.09) 17. Cash used in operations for the year was $6,903,966 18, and cash and cash equivalents on hand at December 31, 2025, were $2,786,493 19. The company's total liabilities were $2,994,054 20, and total stockholders' equity was $3,337,849 21.
Comparing the fiscal year 2025 to 2024, total revenues increased by $34,880, or 83% 22, primarily due to more customer orders 23.

Selling, general, and administrative expenses decreased by $408,333, or 9% 28, mainly due to lower personnel and professional service costs 29. Share-based compensation increased by $109,205, or 11% 30, primarily due to stock option grants in August 2024 and June 2025, partially offset by lower restricted stock unit expenses 31. The impairment loss decreased by $524,481, or 100%, as no impairment loss was recognized in 2025 compared to a $524,481 loss in 2024 related to the sale of manufacturing assets in Switzerland 32. Net loss decreased by $1,297,519, from $9,130,274 in 2024 to $7,832,755 in 2025 33.
During 2025, Ascent Solar Technologies engaged in several significant operational and financing activities. The company closed a public offering on June 30, 2025, issuing 507,000 shares of common stock, 493,000 pre-funded warrants, and 1,000,000 public warrants, generating gross proceeds of approximately $2.0 million 34. Additionally, a private placement on December 5, 2025, involved the issuance of 769,232 shares of common stock, pre-funded warrants for up to 256,411 shares, Series A warrants for up to 1,025,643 shares, and Series B warrants for up to 1,025,643 shares, resulting in gross proceeds of approximately $2.0 million 35. The company also sold 1,022,434 shares of common stock through an At The Market Offering Agreement, generating approximately $2.6 million in gross proceeds 36. Furthermore, 868,000 warrants were exercised during 2025 37.
Business Outlook
Ascent Solar Technologies does not expect that sales revenue and cash flows will be sufficient to support operations and cash requirements until it has fully implemented its strategy of focusing on selling high-value PV products and manufacturing at full industrial scale 38. Projected revenues are not anticipated to result in a positive cash flow position for the year 2025 overall 39. Management believes that additional financing will be required for the company to reach a level of sufficient sales to achieve profitability 40.
The company continues to focus on cell and aerial efficiency improvements on its CIGS-based solar cells, aiming to improve overall performance and efficiencies by minimizing optical losses and improving short-circuit current and open-circuit voltages 41. These R&D efforts are directed towards increasing aerial efficiencies and power-to-weight ratios in the AM0 spectrum 42. Ascent also plans to continue taking advantage of research and development contracts to fund a portion of this development 43.
Operationally, Ascent's growth plan calls for production and operations at its Thornton facility 44. The company intends to significantly expand its operations and form beneficial strategic alliances to reduce manufacturing costs through economies of scale and partnerships, secure commercially material contracts with reputable customers, and capture a meaningful share of its target markets 45. This expansion will require improving operational and financial systems, oversight, procedures, and controls, as well as expanding, training, and managing its growing employee base 46.
Ascent plans to continue investing in research and development to provide near-term improvements to its manufacturing process, including cost reduction, and products, including technology to increase power, as well as to identify next-generation technologies relevant to both existing and potential new markets 47. The company's capital allocation strategy includes securing additional financing through strategic or financial investors 48.
Risk Factors
Ascent Solar Technologies faces several material risks. The company's continuing operations require additional capital, which may not be obtainable on favorable terms or without significant dilution to stockholders, and auditors have expressed substantial doubt about the company's ability to continue as a going concern due to recurring losses and the need for additional financing 49. The company has a limited operating history and has not generated significant revenue, with a net loss of $7,832,755 for the year ended December 31, 2025, and an accumulated deficit of $499,441,465 50. There is a risk that the company's CIGS on flexible plastic substrate technology may not prove commercially viable or achieve expected performance and cost metrics, potentially hindering demand and revenue generation 51. Failure to further refine technology and introduce improved PV products could render its modules uncompetitive or obsolete 52. Expanding manufacturing capability successfully is critical, and risks include cost overruns, delays, and geopolitical unrest 53. The company depends on a limited number of third-party suppliers for key raw materials, and their failure to perform could cause manufacturing delays or increase costs 54. Product quality or performance issues could lead to warranty expenses, damage reputation, and reduce market share 55. Currency translation risk may negatively affect net sales, costs, gross margin, or profitability 56. Significant increases in raw material prices could lead to higher production costs, impacting margins or competitiveness 57. Inadequate intellectual property rights or enforcement means could result in unauthorized use of products or reduced sales 58. Third-party claims of intellectual property infringement could lead to substantial litigation expenses and damages 59. The company's future success depends on retaining its Chief Executive Officer, Mr. Paul Warley, and existing management team, and the inability to attract or retain key personnel would materially harm the business 60. PV modules contain limited amounts of cadmium, and claims of human exposure or future regulations could have a material adverse effect 61. Environmental obligations and liabilities could negatively impact financial condition, cash flows, and profitability 62. Agreements with international parties subject the company to unfavorable political, regulatory, labor, legal, and tax conditions in foreign countries 63. Existing regulations and policies, or changes to them, may present technical, regulatory, and economic barriers to the purchase and use of PV products, significantly reducing demand 64. Risks related to information technology systems include cyber-attacks and non-compliance with privacy laws 65.
Management Priorities
Management's message to shareholders emphasizes the company's focus on commercializing flexible PV modules using proprietary technology for high-value production and specialty solar markets. The company is actively working to improve cell and aerial efficiency of its CIGS-based solar cells, having achieved 15.7% efficiency 66, and is committed to increasing aerial efficiencies and power-to-weight ratios in the AM0 spectrum. Management explicitly states that sales revenue and cash flows are not expected to be sufficient to support operations and cash requirements until the strategy of focusing on high-value PV products and manufacturing at full industrial scale is fully implemented 67. Therefore, securing additional financing through strategic or financial investors is a key priority. The company's strategic priorities include accelerating sales and marketing efforts for specialty PV applications through expanded sales and distribution channels, continuing research and development to drive efficiency improvements and explore next-generation technologies, and managing the expansion of operations and strategic alliances effectively to reduce manufacturing costs and capture market share.
