ASPEN AEROGELS INC

Current report

We are dependent on a single manufacturing facility located in East Providence, Rhode Island, as well as our third-party external manufacturing facility in China. Any significant disruption to these facilities or the failure of any of these facilities to operate according to our expectations could have a material adverse effect on our business and results of operations.

Current report

We are reliant on a single manufacturing facility located in East Providence, Rhode Island, as well as our third-party external manufacturing facility in China, to meet customer demand. Our ability to meet customer demand depends on efficient, proper and uninterrupted operations at our East Providence facility and our external manufacturing facility in China. Accordingly, in the event of a significant disruption to our sole manufacturing facility or third-party external manufacturing facility in China, or breakdown of any production lines, we may not have sufficient inventory in stock to meet demand until the operations can be restored. In addition, power failures or disruptions, the breakdown, failure, or substandard performance of equipment, or the damage or destruction of buildings and other facilities due to fire or natural disasters could severely affect our ability to continue our operations. In the event of such disruptions, we are unlikely to find suitable alternatives or may not be able to make needed repairs on a timely basis and at reasonable cost, which could have a material adverse effect on our business and results of operations. In particular, our manufacturing processes include the use of high pressures, high temperatures, and flammable chemicals, which subject us to a significant risk of loss resulting from fire, spill, or related event.

Current report

In January 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. Until the damaged emissions control unit is replaced, we are reliant on our one remaining emissions control unit, which is older and smaller than the damaged control unit, to continue manufacturing operations at our East Providence facility and to meet customer demand for certain of our products. Furthermore, on April 8, 2026, an explosion occurred at our manufacturing facility in East Providence, Rhode Island. The incident related to a high temperature oven and resulted in damage to a portion of the facility’s production space and temporary cessation of operations. As of May 8, 2026, the facility remains offline. We continue to work with the relevant authorities to execute a plan to resume operations. We expect that restart of operations at the manufacturing facility will be in stages and is dependent on the continued progress of mechanical, operational and safety reviews and our work with local and state agencies. To date, we believe we have mitigated any significant commercial impact of the disruption by working through inventory and by leveraging the capacity of our external manufacturing facility. However, our ability to continue to mitigate the impacts of the disruption assume that the staged restart of our East Providence manufacturing facility proceeds as we currently expect, and that we are able to continue to meet customer demand for our products through a combination of restored production in East Providence, production at our external manufacturing facility, and other efforts to mitigate the impact of the disruptions. If we are unable to resume normal operations at our manufacturing facility in East Providence in a timely manner or manufacture the full array of our products, it may impact our ability to meet customer demand, which could have a material adverse impact on our business, results of operations and financial condition. Even if we are successful in our mitigation efforts, if we experience increased customer demand, we may be unable to produce sufficient product to meet such increased customer demand, which could have a material adverse impact on our business, results of operations and financial condition.

Current report

The insurance policies we maintain to cover losses caused by fire or natural disaster, including business interruption insurance, may not adequately compensate us for any such losses. Moreover, these insurance policies will not address the adverse impacts of any loss of customers that may result from such events and may have large deductibles insufficient to support our continuing operations.

Previous report

The terms of the Credit Agreement with MidCap require us to meet certain operating and financial covenants and/or place restrictions on our operating and financial flexibility. If we raise additional capital through debt financing, the terms of any new debt could further restrict our ability to operate our business.

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 (the MidCap Loan Facility, as amended by Amendment No. 1, the Amended MidCap Loan Facility).

Loans borrowed under the Amended MidCap Loan Facility mature on August 19, 2029.

Previous report

The Amended MidCap Loan Facility is guaranteed by Aspen Mexico Holdings and Aspen Georgia (together with the Borrowers and any future subsidiaries that are required to become guarantors or borrowers pursuant to the terms of the Credit Agreement, collectively, the “Loan Parties”) and is secured by a lien on substantially all existing and after-acquired assets of the Loan Parties, including the equity interest in Aspen RI, Aspen Mexico Holdings and Aspen Georgia owned by us, in each case, subject to customary exceptions.

Previous 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. In addition, 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.

Previous report

We are currently in compliance with the financial covenants set forth in the Amended MidCap Loan Facility and as described above. However, given the decline in our revenues in 2025 as compared to the prior year, there can be no assurance that we will comply with one or more of these financial covenants as of the end of the fourth quarter of 2025. If we default under the terms of the Amended MidCap Loan Facility beyond the applicable grace period, if any, the Lenders may declare all amounts outstanding under the Amended MidCap Loan Facility to be immediately due and payable and terminate all unused commitments to extend further credit under the Amended MidCap Loan Facility. If we are unable to repay the amounts due under the Amended MidCap Loan Facility upon such Lenders’ declaration, the Lenders could proceed against the collateral granted to it to secure the obligations under the Amended MidCap Loan Facility (including, but not limited to taking control of our pledged assets and foreclosing on other collateral). In the event of a default under the terms of the Amended MidCap Loan Facility, the Lenders could also require us to renegotiate the Amended MidCap Loan Facility on terms less favorable to us. Either the enforcement by the Lenders upon its declaration to accelerate the obligations under the Amended MidCap Loan Facility or the renegotiation of the Amended MidCap Loan Facility’s terms, each as mentioned above, could adversely affect our operations. Further, if we are liquidated, the Lenders’ right to repayment, as well as the right to repayment of other lenders under any additional debt financing, would be senior to the rights of the holders of our common stock. The Lenders’ interests as lenders may not always be aligned with our interests. If our interests come into conflict with those of the Lenders, including in the event of a default or an Event of Default (as defined in the Amended MidCap Loan Facility) under the Amended MidCap Loan Facility, the Lenders may choose to act in its self-interest, which could adversely affect the success of our current and future collaborative efforts with the Lenders.
