Aspen Aerogels, Inc. Reports Third Quarter 2026 Financial Results and Recent Business Highlights
East Providence incident-related costs totaled $15.1 million in Q3, with another $5 million to $10 million estimated for Q4.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
Aspen Aerogels (NYSE: ASPN) reported third-quarter 2026 revenue of $85.2 million, exceeding the high end of its outlook. Revenue rose 71% quarter over quarter, versus $73.0 million a year earlier. Thermal Barrier revenue was $45.3 million and Energy Industrial revenue was $39.9 million.
Net loss widened to $10.4 million from $6.3 million a year earlier. Results included $15.1 million in East Providence incident-related costs and a $4.6 million asset-disposal loss. Adjusted EBITDA, a non-GAAP earnings measure, rose to $19.8 million from $6.3 million. Quarter-end cash, cash equivalents and restricted cash totaled $146.5 million.
Aspen expects Q4 revenue of $60 million–$75 million and a net loss of $8 million–$11 million. Its first data center infrastructure order is expected to ship in Q4. Restoration of East Providence production capability remains on track for the first half of 2027.
How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.

See Special Note Regarding Forward-Looking and Cautionary Statements below.
Conference Call and Webcast Notification
A conference call with Aspen management to discuss third quarter 2026 results and recent business developments will be held Thursday, November 5, 2026, at 8:30 a.m. ET. During the call, management will respond to questions concerning, but not limited to, Aspen’s financial performance, business conditions, and financial outlook. Management’s discussion and responses could contain information that has not been previously disclosed.
Shareholders and other interested parties may call +1 (833) 461-5787 (domestic) or +1 (585) 542-9983 (international) and reference Meeting ID “525590106” to participate in the conference call. In addition, the conference call and an accompanying slide presentation will be available live as a listen-only webcast hosted at the Investors section of Aspen’s website, www.aerogel.com.

Non-GAAP Financial Measures
In addition to providing financial measurements based on generally accepted accounting principles in the United States of America (“GAAP”), Aspen provides additional financial metrics that are not prepared in accordance with GAAP (“non-GAAP”). The non-GAAP financial measures included in this press release are Adjusted EBITDA, Adjusted EBITDA margin, adjusted net income (loss), adjusted net income (loss) per share, adjusted gross profit, and adjusted gross margin. Management uses these non-GAAP financial measures, in addition to GAAP financial measures, as a measure of operating performance because the non-GAAP financial measures do not include the impact of items that management does not consider indicative of Aspen's core operating performance. These excluded items include the loss on disposal of property, plant and equipment and costs related to the East Providence incidents, including expedited freight and expedited repair costs, professional fees; and the incremental cost of temporarily sourcing certain products from the Company's external manufacturing facility until the East Providence facility returns to full production capacity. In addition, management uses Adjusted EBITDA (i) for planning purposes, including the preparation of Aspen's annual operating budget, (ii) to allocate resources to enhance the financial performance of its business, and (iii) as a performance measure under its bonus plan.
Management believes that these non-GAAP financial measures reflect Aspen's ongoing business in a manner that allows for meaningful comparisons and analysis of trends in its business, as it excludes expenses and gains not reflective of Aspen's ongoing operating results or that may be infrequent and/or unusual in nature. Management also believes that these non-GAAP financial measures provide useful information to investors in understanding and evaluating Aspen's operating results and future prospects in the same manner as management and in comparing financial results across accounting periods and to those of peer companies. These non-GAAP measures may not be comparable to similarly titled measures presented by other companies.
The non-GAAP financial measures do not replace the presentation of Aspen's GAAP financial results and should only be used as a supplement to, not as a substitute for, Aspen's financial results presented in accordance with GAAP. In this press release, Aspen has provided a reconciliation of Adjusted EBITDA to net income (loss), Adjusted EBITDA margin to net loss margin, adjusted net income (loss) to net loss, adjusted net income (loss) per share to net loss per share, adjusted gross profit to gross profit, and adjusted gross margin to gross margin, in each case to the most directly comparable GAAP financial measure. Management strongly encourages investors to review Aspen's financial statements and publicly filed reports in their entirety and not rely on any single financial measure.

Reconciliation of Non-GAAP Financial Measures
The following tables present reconciliations of the non-GAAP financial measures included in this press release to the most directly comparable GAAP measures:
Reconciliation of Adjusted EBITDA to Net Loss
We define Adjusted EBITDA as net income (loss) before interest expense, taxes, depreciation, amortization, stock-based compensation expense and other items, which occur from time to time and which we do not believe are indicative of our core operating performance. We define Adjusted EBITDA margin as Adjusted EBITDA divided by revenue, and net loss margin as net loss divided by revenue.
