Rhea-AI Filing Summary

Aspen Aerogels reported second quarter 2026 revenue of $49.8 million, down from $78.0 million a year earlier, as Thermal Barrier and Energy Industrial sales declined year-over-year amid changes to North American EV regulatory frameworks. Thermal Barrier revenue was $29.5 million versus $55.2 million, while Energy Industrial revenue was $20.4 million versus $22.8 million. Net loss widened to $23.3 million (or $0.28 per share) from $9.1 million (or $0.11 per share), and Adjusted EBITDA moved to a loss of $(6.6) million from a profit of $9.7 million.

Results reflected an $8.9 million loss on property damage from the April 2026 East Providence incident, offset by an equal insurance recovery receivable, plus $5.3 million of other incident-related costs that Aspen plans to claim under business interruption coverage. Despite this disruption, total revenue grew 32% quarter-over-quarter and Thermal Barrier revenue increased 81% quarter-over-quarter, supported by stabilizing North American EV demand and European momentum. The company highlighted a PyroThin® award from Jaguar Land Rover for two next-generation vehicle architectures and ended the quarter with $153.4 million in cash, cash equivalents and restricted cash. For Q3 2026, Aspen guides to revenue of $65–$80 million, net loss of $6–$9 million, and positive Adjusted EBITDA of $7–$15 million, excluding an estimated $5–$10 million of additional incident-related costs.

Positive

  • Guidance to positive Adjusted EBITDA in Q3 2026 with an outlook of $7–$15 million on revenue of $65–$80 million signals management’s expectation of a near-term improvement from the Q2 Adjusted EBITDA loss.
  • Thermal Barrier recovery and new OEM win: Thermal Barrier revenue rose 81% quarter-over-quarter to $29.5 million, and Aspen secured a PyroThin® award for two Jaguar Land Rover next-generation vehicle architectures, with start of production expected in 2027.
  • Strong liquidity and improved operating cash flow: Cash, cash equivalents and restricted cash totaled $153.4 million, and operating activities provided $17.9 million of cash in the first six months of 2026, compared to $1.7 million in the prior-year period.

Negative

  • Q2 2026 revenue declined to $49.8 million from $78.0 million, with both Thermal Barrier and Energy Industrial segments down year-over-year, compressing gross profit to $3.3 million from $25.3 million.
  • Loss profile worsened versus prior year: Net loss increased to $23.3 million from $9.1 million, and Adjusted EBITDA shifted from a $9.7 million profit to a $(6.6) million loss, reflecting lower volumes and East Providence incident impacts.
  • Operational and cost impact from East Providence incident: Aspen recorded an $8.9 million property damage loss and $5.3 million of other incident-related costs, and expects to incur an additional $5–$10 million of related costs in Q3 2026.

Filing Explained

At June 30, Aspen had 153.4 million dollars of liquidity, but its 8.9 million dollar insurance receivable remained uncollected.

The August 6, 2026 Form 8-K reports completed second-quarter results and provides a third-quarter outlook; at June 30, 2026, Aspen reported $153.4 million of cash, cash equivalents and restricted cash after using $16,200 thousand in operating activities during the quarter.

The $8.9 million insurance-recovery receivable was recognized in the second quarter and is expected to be collected in the third quarter, while the third-quarter outlook does not assume any business-interruption insurance recoveries; the receivable is therefore recorded but not reported as collected cash.

For the Statesboro, Georgia manufacturing assets, the previously disclosed non-binding letter of intent expired without a definitive agreement, and Aspen continues marketing the assets, so a sale and related proceeds remain uncommitted.

Adjusted EBITDA financial
"Adjusted EBITDA was $(6.6) million, compared to $9.7 million"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
business interruption insurance financial
"the Company plans to submit claims under its business interruption insurance"
Business interruption insurance is a policy that helps a company replace lost revenue and cover ongoing expenses when normal operations are halted by a covered event, such as property damage, supply-chain disruption, or other insured perils. For investors it acts like a financial safety net that preserves cash flow and reduces the chance of long-term harm after a shock, influencing a firm’s revenue stability, credit risk, and valuation.
sale and leaseback transactions financial
"Finance obligation for sale and leaseback transactions long-term"
non-GAAP financial measures financial
"The non-GAAP financial measures included in this press release are Adjusted EBITDA"
Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.
forward-looking statements regulatory
"This press release and any related discussion contains “forward-looking statements”"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
Revenue $49.8 million compared to $78.0 million in the prior-year quarter
Net loss $23.3 million compared to $9.1 million in the prior-year quarter
Adjusted EBITDA $(6.6) million compared to $9.7 million in the prior-year quarter
Thermal Barrier revenue $29.5 million up 81% quarter-over-quarter and compared to $55.2 million in the prior-year quarter

For Q3 2026, Aspen expects revenue of $65–$80 million, net loss of $6–$9 million, net loss per share of $0.07–$0.11, and Adjusted EBITDA of $7–$15 million, excluding an estimated $5–$10 million of additional East Providence incident-related costs.

Aspen Aerogels, Inc. Reports Second Quarter 2026 Financial Results and Recent Business Highlights

Q2 2026 Thermal Barrier revenue of $29.5 million, up 81% quarter-over-quarter
Q3 2026 expected revenue range of $65 to $80 million and adjusted EBITDA range of $7 to $15 million
European Thermal Barrier 2026 revenue outlook raised to $20 to $30 million
PyroThin® award from Jaguar Land Rover for two next-generation vehicle architectures

NORTHBOROUGH, Mass., Aug. 06, 2026 (GLOBE NEWSWIRE) -- Aspen Aerogels, Inc. (NYSE: ASPN) (“Aspen” or the “Company”), a technology leader in sustainability and electrification solutions, today announced financial results for the second quarter of 2026, and discussed recent business developments.

Second Quarter 2026 Results
Total revenue for the second quarter of 2026 was $49.8 million, compared to $78.0 million in the prior year period. Thermal Barrier segment revenue was $29.5 million, compared to $55.2 million in the prior year period, reflecting the impact of changes to North American EV regulatory frameworks and incentive programs. Energy Industrial segment revenue was $20.4 million, compared to $22.8 million in the prior year period.

Net loss was $23.3 million, compared to net loss of $9.1 million in the prior year period. Second quarter 2026 results included an $8.9 million loss on property damage related to the April 2026 East Providence incident, offset by a corresponding receivable for an estimated $8.9 million insurance recovery recognized in other income. The Company expects to collect this receivable in the third quarter of 2026. Results also included $5.3 million of other incident-related costs, such as expedited freight and professional fees, for which the Company plans to submit claims under its business interruption insurance. Second quarter 2025 results included a $1.0 million impairment charge related to the demobilization of the Company's previously planned manufacturing facility in Statesboro, Georgia, and $4.9 million in restructuring and demobilization costs. Excluding these items, adjusted net loss for the second quarter of 2026 was $17.9 million, compared to adjusted net loss of $3.2 million in the prior year period.

Net loss per share was $0.28, compared to net loss per share of $0.11 in the prior year period. Excluding the items described above, adjusted net loss per share was $0.22, compared to adjusted net loss per share of $0.04 in the prior year period.

Adjusted EBITDA was $(6.6) million, compared to $9.7 million in the prior year period. Adjusted EBITDA for the second quarter of 2026 excludes the $5.3 million of incident-related costs described above, which the Company does not consider indicative of its core operating performance. The $8.9 million loss on property damage was offset by a corresponding receivable for an estimated insurance recovery and had no net impact on Adjusted EBITDA.

A reconciliation of non-GAAP financial results to GAAP financial results is provided in the financial schedules that are part of this press release. An explanation of these non-GAAP financial measures is also included below under the heading “Non-GAAP Financial Measures.”

Recent Business Highlights & Financial Performance

  • Initiated a staged restart of our manufacturing facility in East Providence, Rhode Island; maintained customer supply throughout the quarter through a combination of existing inventory, production from the external manufacturing facility, and limited production from the East Providence manufacturing facility
  • Delivered total revenue of $49.8 million, a 32% increase quarter-over-quarter (QoQ)
  • Increased Thermal Barrier revenue 81% QoQ to $29.5 million, reflecting stabilizing North American program volumes and continued European OEM revenue momentum
  • Secured a PyroThin® award across two of Jaguar Land Rover's (JLR) next-generation vehicle architectures, supporting multiple JLR brands, with start of production expected in 2027
  • Ended the quarter with cash, cash equivalents, and restricted cash of $153.4 million
  • Continues to pursue the sale of the Statesboro, Georgia manufacturing assets. The previously disclosed non-binding letter of intent with respect to a potential sale expired without a definitive agreement, and the Company is actively marketing the assets to prospective buyers

“The second quarter demonstrated the resilience of our team and the durability of our business. As we managed through the East Providence incident, we kept our customers supplied, advanced the facility’s staged restart, and strengthened the long-term flexibility of our operations. We enter the third quarter with solid momentum, supported by accelerating Energy Industrial project activity, stabilizing North American Thermal Barrier demand, and the continued ramp in European Thermal Barrier revenue. We believe these drivers position Aspen for sustained, profitable growth in 2027 and beyond,” said Don Young, President and CEO.

Financial Outlook
Aspen issues its financial outlook as follows:

  • Q3 2026 Revenue is expected to range between $65 million and $80 million
  • Q3 2026 Net loss is expected to range between $6 million and $9 million
  • Q3 2026 Net loss per share is expected to range between $0.07 and $0.11
  • Q3 2026 Adjusted EBITDA is expected to range between $7 million and $15 million, which excludes an estimated $5 million to $10 million of costs related to the East Providence incident, including expedited freight, professional fees, and the incremental cost of temporarily sourcing certain Energy Industrial products from the Company's external manufacturing facility until the East Providence facility returns to full production capacity; the Company expects to submit claims related to these costs under its insurance policies
  • FY 2026 Capital Expenditures, excluding costs related to the restoration of the East Providence facility, are expected to be less than $10 million

Grant Thoele, Chief Financial Officer and Treasurer, noted, “Our third-quarter outlook of $65 million to $80 million in revenue and $7 million to $15 million in Adjusted EBITDA represents a meaningful improvement in financial performance. Despite elevated costs related to the East Providence incident in the second quarter, we maintained solid liquidity and plan to submit insurance claims for these costs. We remain focused on disciplined cost management and rebuilding our earnings power.”

The Company's Q3 2026 outlook assumes depreciation and amortization of $5.0 million, stock-based compensation expense of $3.0 million, net interest expense of $3.0 million, and diluted weighted average shares outstanding of 83.0 million for the quarter. The Adjusted EBITDA range excludes an estimated $5 million to $10 million of costs related to the East Providence incident and described above. The net loss and Adjusted EBITDA ranges do not assume any business interruption insurance recoveries related to the East Providence incident.

A reconciliation of net loss to non-GAAP Adjusted EBITDA for the Q3 2026 financial outlook is provided in the financial schedules that are part of this press release. An explanation of this non-GAAP financial measure is also included below under the heading “Non-GAAP Financial Measures.”

Aspen may incur, among other items, additional charges, realize gains or losses, incur financing costs or interest expense, or experience other events in 2026, including those related to the recovery from the East Providence incident, the staged restart of the East Providence manufacturing facility, operational disruptions, supply chain disruptions, or further cost inflation, that could cause actual results to vary materially from this outlook. See Special Note Regarding Forward-Looking and Cautionary Statements below.

Conference Call and Webcast Notification
A conference call with Aspen management to discuss second quarter 2026 results and recent business developments will be held Thursday, August 6, 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 (626) 884-3620 (international) and reference Meeting ID “735343488” 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.

Following the live event, an archived version of the webcast will be available on Aspen’s website for convenient on-demand replay for approximately one year. A copy of this press release is posted in the Investors section on Aspen’s website.

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 net loss and adjusted net loss per share. 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 costs related to the East Providence incident, including expedited freight, professional fees, and the incremental cost of temporarily sourcing certain Energy Industrial 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 net loss to net loss and adjusted net loss per share to net loss per share, 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.
