On May 6, 2025, the Borrowers and Aspen Aerogels Georgia, LLC, a Georgia limited liability company (Aspen Georgia), entered into that certain Amendment No. 1 and Joinder to Credit, Security and Guaranty Agreement (Amendment No. 1), by and among the Borrowers, Aspen Georgia, the Agent and the Lenders party thereto, amending the MidCap Loan Facility and on December 16, 2025, the Borrowers, Aspen Georgia, and Aspen Aerogels Mexico Holdings, LLC, a Delaware limited liability company (Aspen Mexico), entered into that certain Amendment No. 2 and Joinder to Credit, Security and Guaranty Agreement (Amendment No. 2), by and among the Borrowers, Aspen Georgia, Aspen Mexico, the Agent and the Lenders party thereto, further amending the MidCap Loan Facility (the MidCap Loan Facility, as amended by Amendment No. 1 and Amendment No. 2, the Amended MidCap Loan Facility).

Current report

Pursuant to Amendment No. 1, the financial covenants under the MidCap Loan Facility were amended such that (a) the minimum Liquidity (as defined in the Amended MidCap Loan Facility) which must be maintained at all times has changed from $75 million to an amount equal to the greater of (i) $50 million and (ii) 85% of the then aggregate outstanding principal amount of the Term Loan Facility and (b) the minimum EBITDA level to be tested quarterly has changed to reflect a new range from $15 million to $50 million, with the next test set at $15 million with respect to the fiscal quarter ended June 30, 2025 and a $50 million level applicable commencing with the fiscal quarter ended December 31, 2027 and thereafter. The Liquidity amount trigger of a cash dominion event was also reduced from $100 million to an amount equal to the greater of (i) $50 million and (ii) 85% of the then aggregate outstanding principal amount of the Term Loan Facility.

Current report

Pursuant to Amendment No. 2, the financial covenants under the MidCap Loan Facility have been amended such that (a) the applicable minimum liquidity threshold (both for (i) the minimum liquidity financial covenant, which must be maintained by the Company at all times and (ii) the “Cash Dominion Event” definition for purposes of triggering cash dominion) has changed from (i) an amount equal to the greater of (x) $50 million and (y) 85% of the then aggregate outstanding principal amount of the Term Loan (as defined in the Amended MidCap Loan Facility) to (ii) an amount equal to the greater of (x) $50 million and (y) 100% of the then aggregate outstanding principal amount of the Term Loan (as defined in the Amended MidCap Loan Facility) and (b) the minimum EBITDA (as defined in the Amended MidCap Loan Facility) financial maintenance covenant has been removed entirely.

Current report

The Amended MidCap Loan Facility includes representations and warranties, affirmative covenants (including reporting obligations), negative covenants and events of default that are usual and customary for facilities of this type, in each case, subject to certain permitted exceptions as set forth therein. In addition, the mandatory prepayment provisions were revised to make clear that any mandatory prepayment of the loans under the Amended MidCap Loan Facility made with proceeds of an asset sale will be used to reduce the Company’s required amortization payments in direct order of maturity, and the basket for making permitted acquisitions under the Amended MidCap Loan Facility was reduced.

Current report

During 2025, we experienced a significant decline in volume for our thermal barrier products, primarily driven by lower North American EV production levels. As a result, total revenue decreased by 40% compared to the prior year. Our expectation for 2026 thermal barrier revenue is based, in part, on our OEM customers’ production forecasts. The automotive industry in which our OEM customers operate is cyclical and is sensitive to changes in consumer demand, regulatory environments, and broader economic conditions. EV adoption rates in certain markets have been lower than previously anticipated, influenced in part by changes in regulatory frameworks and incentive programs as well as evolving consumer demand. OEMs have adjusted production plans and investment timelines accordingly. These actions have resulted in revised capacity plans and re-timed EV-related investments, particularly in North America. In addition, changes in trade policy and other macroeconomic factors have impacted both our customers and our operating environment, and we expect these conditions to continue to influence demand. OEM customers continue to pursue cost reduction and product redesign initiatives, which may result in engineering changes to the components we supply. Our supply agreements generally include pricing step-down provisions over the production life of a program, consistent with industry practice. We expect thermal barrier revenues to decline in 2026, primarily due to lower anticipated production volumes. In February 2026, there was a fire at our manufacturing facility in East Providence, Rhode Island, which damaged one of our emissions control units and rendered it inoperable. If our remaining emissions control unit were to fail or otherwise cease to operate before the damaged unit is replaced, or if demand for our products increases materially before our damaged emissions control is replaced, we may not able to meet customer demand for our products, which could have a material adverse impact our revenue and earnings.

Current report

We expect energy industrial revenue to increase in 2026, driven by anticipated volume growth in our core petrochemical and refinery markets, project-based demand, and continued penetration into adjacent applications.

Current report

In response to these developments, we plan to continue cost reduction measures, including reduced headcount and operational efficiency initiatives. As a result, we expect Adjusted EBITDA to decline in 2026 primarily due to lower thermal barrier revenue. However, we expect net loss to improve relative to 2025, as the impairment recorded for the previously planned second plant in Statesboro, Georgia is not expected to recur. We also expect capital expenditures to decrease in 2026.

Current report

During 2026, we expect gross profit to decline in absolute dollars and as a percentage of revenue due to expected decreases in total revenue and production volumes, offset partially by manufacturing productivity.

Current report

Restructuring and demobilization costs consists of severance and other personnel costs, and costs associated with the demobilization of our previously planned Statesboro Plant.

Current report

During the fiscal year ended December 31, 2025, loss on disposal of property, plant and equipment consists of charges to remeasure at fair value less costs to sell the assets of our previously planned Statesboro Plant which have been classified as assets held for sale.

Current report

During the fiscal year ended December 31, 2025, impairment of property, plant and equipment consists of impairment incurred on our previously planned Statesboro Plant and impairment of other property, plant and equipment in connection with a restructuring action.

Current report

Total cost of revenue decreased $44.7 million, or 17%, to $225.1 million in 2025 from $269.8 million in 2024 driven by declines in both thermal barrier and energy industrial cost of revenues.

Current report

Energy industrial cost of revenue decreased $22.4 million, or 26%, to $65.0 million from $87.4 million in the comparable period in 2024. The $22.4 million decrease was the result of a $13.7 million decrease in material costs and an $8.7 million decrease in manufacturing and other operating costs due to lower volume in comparison to the same period in 2024.

Current report

Thermal barrier cost of revenue decreased $22.3 million to $160.1 million as compared to $182.4 million in the comparable period in 2024. The $22.3 million decrease was the result of a $44.4 million decrease in material cost, partially offset by accelerated depreciation of $22.1 million on certain assets whose useful lives were lowered to align utilization with revised expected demand. Material costs decreased primarily due to lower volume and operational efficiencies generating lower scrap.

Current report

Gross profit decreased $136.9 million, or 75%, to $46.0 million in 2025 from $182.9 million in 2024. The decrease in gross profit was the result of the $181.6 million decrease in total revenue, partially offset by the $44.7 million decrease in total cost of revenue.

Current report

Research and development expenses decreased by $4.7 million, or 26%, to $13.4 million in 2025 from $18.1 million in 2024. The $4.7 million decrease was the result of decreases in compensation and related costs of $4.4 million, driven by a headcount reduction, operating supplies and equipment of $0.4 million, and professional fees of $0.2 million, partially offset by an increase in other expenditures of $0.3 million.

Current report

Research and development expenses as a percentage of total revenue increased to 5% during the year ended December 31, 2025 from 4% in the comparable period in 2024 primarily due to the 40% decrease in revenue from the comparable period in 2024.

Current report

Sales and marketing expenses decreased by $7.5 million, or 21%, to $28.2 million in 2025 from $35.7 million in 2024. The decrease was the result of decreases in compensation and related costs of $5.2 million, driven by a headcount reduction, employee-related expenses of $1.0 million, marketing expenses of $0.6 million, operating supplies and equipment of $0.5 million, and other expenditures of $0.2 million.

Current report

Sales and marketing expenses as a percentage of total revenue increased to 10% in 2025 from 8% in 2024 primarily due to the 40% decrease in revenue from the comparable period in 2024.

Current report

General and administrative expenses decreased by $15.3 million, or 22%, to $55.8 million in 2025 from $71.1 million in 2024. The $15.3 million decrease was the result of decreases in compensation and related costs of $15.9 million, driven by a headcount reduction, employee-related expenses of $0.7 million, foreign currency transaction losses of $2.4 million and professional fees of $1.6 million, partially offset by an increase in bad debt expense of $3.3 million, utilities expenses of $1.7 million and other expenditures of $0.3 million. Compensation and related costs for the year ended December 31, 2024 included $2.0 million of charge from the cancellation of the unearned performance-based restricted shares.

Current report

In February 2025, we announced and began implementing a restructuring plan to realign our operational focus to improve costs and align capital expenditure to anticipated long term demand. The plan included reducing our headcount and ceasing construction of our previously planned Statesboro Plant. In connection with the demobilization, we are no longer pursuing our application for a loan from the Department of Energy's Loan Programs Office and have withdrawn from the loan application process. During each of the three months ended June 30, 2025, September 30, 2025 and December 31, 2025, we announced further headcount reductions to realign our operations and to improve costs. Restructuring and demobilization costs for the year ended December 31, 2025 include severance and other personnel costs of $8.2 million, facility closures and other costs associated with demobilization of $3.1 million and a write off of deferred financing costs of $6.2 million incurred in connection with pursuing financing for the construction of the Statesboro Plant. We did not incur restructuring and demobilization costs for the year ended December 31, 2024.

Current report

Loss on disposal of property, plant and equipment consists of $18.2 million in charges to remeasure at fair value less costs to sell the assets of our previously planned Statesboro Plant which have been classified as assets held for sale.

Current report

Impairment of property, plant and equipment costs increased $287.7 million, to $291.2 million, for the year ended December 31, 2025 from $3.5 million in the comparable period in 2024. The increase was due to impairment of $286.6 million on our previously planned Statesboro Plant and impairment of $4.6 million incurred on research and development equipment and construction in progress that are no longer needed due to lower forecasted demand in the Thermal Barrier business. Impairment of $3.5 million for the comparable period in 2024 was the result of a charge for impairment of assets due to obsolescence following development of new and more efficient equipment.

Current report

The $7.6 million decrease in interest expense, related party for the year ended December 31, 2025 is the result of the repurchase of the 2022 Convertible Note in August 2024.

Current report

The $6.3 million increase in interest expense, net for the year ended December 31, 2025 is the result of a $9.9 million increase in interest expense from the Amended MidCap Loan Facility and sale and leaseback transactions, offset by $1.8 million of deferred financing costs written off related to the loan agreement with GM (the GM Loan Agreement) during the three months ended March 31, 2024 which did not repeat during the comparable period, and an increase in interest income of $1.8 million.

Current report

The $27.5 million loss on extinguishment of debt for the year ended December 31, 2025 is the result of the repayment of the 2022 Convertible Note in August 2024.

Current report

The $1.8 million increase in other income for the year ended December 31, 2025 is primarily due to a $1.1 million legal settlement payment to us.

Previous report

On March 16, 2022, we entered into a sales agreement for an at-the-market offering program with Cowen and Company, LLC and Piper Sandler & Co., as our sales agents (the 2022 ATM offering program). During the year ended December 31, 2022, we sold 5,241,400 shares of our common stock through the 2022 ATM offering program and received net proceeds of $72.7 million. The 2022 ATM offering program was terminated on June 20, 2023.

Previous report

On March 28, 2022, we sold to an affiliate of Koch, 1,791,986 shares of our common stock for aggregate gross proceeds of $50.0 million, pursuant to a securities purchase agreement, dated as of February 15, 2022, by and between us and the affiliate of Koch.

Previous report

On November 29, 2022, we completed an underwritten public offering of 29,052,631 shares of our common stock at a public offering price of $9.50 per share. We received net proceeds of $267.5 million after deducting underwriting discounts and commissions of $8.1 million and offering expenses of approximately $0.5 million.

Previous report

During 2024, we experienced strong volume growth in our thermal barrier products. As a result, we experienced total revenue growth of 90% during the year. Our expectation for 2025 revenue is based, in part, on our OEM customers’ production volume forecasts and targets. Our OEM customers operate in a cyclical industry that is sensitive to shifting consumer trends, political and regulatory uncertainty and economic conditions in the markets they operate. EV adoption rates in some of our customers’ markets are expected to be at a slower rate than originally expected and EV investment continues to be re-timed as demand expectations in North America and Europe are reset. However, some of our OEM customers have been gaining market share from a low base volume and expect to continue to gain market share in 2025. Furthermore, changes are being considered to government and economic policies, incentives, and tariffs that may impact our customers and our production, sales, cost structure and the competitive landscape. Additionally, our OEM customers continue to innovate which could result in engineering changes to the parts we supply primarily to reduce costs for our OEMs. Cost-cutting initiatives adopted by our customers may result in increased downward pressure on pricing. Accordingly, we expect thermal barrier revenues could range from a decline to moderately higher in 2025. However, we are expecting an increase in energy industrial revenues. We are projecting growth in energy industrial revenue due to expected volume growth in our core petrochemical and refinery markets, an anticipated increase in project-based demand and continued penetration of new markets. We will continue to adjust to these developments, and we believe our ongoing cost reduction, including improved production innovation and efficiency, will continue to benefit us. As a result, we expect to experience a decline to no or minimal growth in net income and Adjusted EBITDA during 2025. We also expect to incur reduced capital expenditures during 2025.

Previous report

In the longer term, we expect gross profit to improve in absolute dollars and as a percentage of revenue due to expected increases in total revenue, production volumes and manufacturing productivity. In addition, we expect the gross profit improvement derived from the increases in revenue, volume and productivity will be supported by the continued implementation of lower cost product formulations and realization of material purchasing efficiencies.

Previous report

Energy industrial cost of revenue decreased $11.5 million, or 11%, to $94.5 million from $106.0 million in the comparable period in 2022. The $11.5 million decrease was the result of a $11.4 million decrease in material costs and a $0.1 million decrease in manufacturing and other operating costs from the comparable period in 2022. The decrease in material costs was the result of the lower revenue volume from the comparable period in 2022, and lower raw material costs in 2023 compared to 2022.

Previous report

Thermal barrier cost of revenue increased $17.9 million to $87.3 million as compared to $69.4 million in the comparable period in 2022. The $17.9 million increase was the result of a $5.8 million increase in material costs and a $12.1 million increase in manufacturing costs. The increase in material costs was the result of the increase in revenue volume from the comparable period in 2022, offset by lower raw material prices in 2023 compared to 2022. The increase in manufacturing costs was driven by increases in depreciation and facility costs of $7.1 million and utilities expenses of $3.3 million and other manufacturing and operating costs of $1.7 million.

Previous report

Research and development expenses decreased by $0.5 million, or 3%, to $16.4 million in 2023 from $16.9 million in 2022.

Previous report

Sales and marketing expenses increased by $4.2 million, or 15%, to $33.0 million in 2023 from $28.8 million in 2022. The increase was the result of increases in depreciation and facility related expenses of $2.9 million and compensation and related costs of $2.1 million, partially offset by a decrease in operating material and supplies costs of $0.8 million.

Previous report

General and administrative expenses increased by $18.3 million, or 47%, to $56.8 million in 2023 from $38.5 million in 2022. The $18.3 million increase was the result of increases in compensation and related costs of $15.3 million and professional fees of $3.6 million, offset by a decrease in other costs of $0.6 million.

Previous report

General and administrative expenses as a percentage of total revenue increased to 24% in 2023 from 21% in 2022 primarily due to increased expenditures associated with the growth in our human resource, finance, information technology and general management organizations in preparation for the anticipated growth in our business.

Previous report

Other income (expense), net increased by $6.9 million to $3.4 million in 2023 from $(3.5) million in 2022. The $6.9 million increase was the result of $4.9 million of interest income, $2.2 million of Employee Retention Credits and a $(0.2) million net impact of capitalized interest relating to our Convertible Note in the comparable period in 2022.

Previous report

Our long-term financial projections anticipate revenue growth, increasing levels of gross profit, and improved cash flows from operations. To meet expected demand for our aerogel products, we plan to make additional productivity improvements in our existing East Providence facility and utilize a flexible supply strategy, including but not limited to use of our external manufacturing capabilities in China, which currently support Aspen’s Energy Industrial segment and are capable of delivering increased aerogel production capacity. We expect that the productivity improvements in our existing East Providence facility as well as the supply from our external manufacturing facility will permit us to achieve our target revenue capacity in 2025 and in the long-term. Accordingly, we have ceased construction at our previously planned second manufacturing plant in Statesboro, Georgia. We will be demobilizing the plant and are in the process of assessing options to derive value from the assets, including potentially relocating certain equipment to improve and expand our existing manufacturing facility in East Providence.

Previous report

On October 16, 2024, we announced that the U.S. Department of Energy (DOE) Loan Programs Office provided us a conditional commitment for a proposed loan of up to $670.6 million (the Loan) under the Advanced Technology Vehicles Manufacturing loan program within DOE’s Loan Programs Office (LPO) for financing the construction of our previously planned second aerogel manufacturing facility (the Statesboro Plant) in Statesboro, Georgia. On February 12, 2025, we announced that we had stopped construction on the Statesboro Plant and are demobilizing the project. In connection with the demobilization, we are no longer pursuing our application for the Loan from the DOE’s LPO and have withdrawn from the Loan application process.
