Business Overview
Aspen Aerogels designs and manufactures high-performance aerogel insulation materials, generating revenue from two primary segments: energy industrial (thermal insulation for industrial and LNG applications) and EV thermal barriers (PyroThin, a thermal runaway mitigation product for electric vehicle batteries). The company’s business model combines proprietary manufacturing with contract supply, aiming to leverage its aerogel technology platform across industrial, automotive, and emerging battery materials markets.
Performance Analysis
Q2 2023 marked a pivotal operational and financial shift for Aspen Aerogels. Total revenue grew 6% year over year, constrained by planned plant downtime for upgrades, yet gross profit improved sharply. The energy industrial segment delivered a record 27% gross margin, up from prior quarters, reflecting product mix optimization and efficiency gains. EV thermal barrier revenue rose 17% YoY, though the segment still posted a gross loss, mitigated by automation and lower break-even thresholds.
Material costs fell to 36% of sales, below Aspen’s 40% target, due to procurement wins. Conversion costs, while still elevated at 46% of sales, trended downward as Mexican operations ramped. Adjusted EBITDA loss narrowed 41% YoY, and net loss improved by $8.7 million from last year. Operating expenses held steady at $25 million for the third consecutive quarter, reflecting disciplined scaling ahead of anticipated revenue inflection.
- Backlog and Supply Constraints: $138 million in energy industrial backlog highlights robust demand, but capacity remains a gating factor pending supplemental supply ramp.
- EV Segment Break-Even Progress: Automation lowered PyroThin’s gross profit break-even to $15 million in quarterly revenue, down from $20 million.
- Cash and CapEx Management: Aspen ended Q2 with $134 million in cash, while CapEx focused on Plant 2 preservation and Mexico tooling, with strict limits pending clearer EV demand signals.
The financial trajectory now hinges on GM’s EV production ramp and successful execution of the supplemental supply agreement, both of which are poised to unlock latent revenue and margin gains.
Executive Commentary
"The implementation of this supplemental supply arrangement allows us to focus on driving significant profitability from our existing resources and opportunities. We believe that we are building a business around our current assets and near-term commercial opportunities that has the potential to produce annually approximately $550 million of revenue, approximately $200 million of gross profit, and approximately $140 million of EBITDA."
Don Young, President and CEO
"Our adjusted EBITDA was negative $10.8 million in Q2 compared to negative $18.3 million during the same period last year, resulting in a year-over-year reduction in our EBITDA loss of 41%. When we compare our year-to-date adjusted EBITDA loss of $24.8 million with our original expectations for the first half of 2023, we're $14 million ahead of those plans."

Strategic Positioning
1. Supplemental Supply Arrangement as Margin Lever
Outsourcing production to a contract manufacturer for energy industrial products is a structural shift, freeing Aspen’s Rhode Island plant for PyroThin EV thermal barrier production. This move reduces lead times, aligns with a 35% gross margin target, and unlocks incremental revenue otherwise constrained by capacity.
2. EV Thermal Barrier Ramp and Design Wins
PyroThin, Aspen’s EV battery thermal runaway mitigation solution, is central to growth strategy. The company is supplying GM, Toyota, and a major European commercial truck OEM, with near-term line of sight on three additional EV OEM awards. These wins will diversify revenue, especially as European prismatic cell designs accelerate adoption.
3. Cost Structure Optimization and Operational Discipline
Material and conversion cost reductions, driven by supply chain normalization and automation in Mexico, are improving margins. OPEX is being tightly managed, with recent increases tied to strategic investments in EV ramp readiness. The company’s stated aim is to halve conversion costs as a percentage of sales with scale.
4. Capital Allocation and Balance Sheet Flexibility
CapEx is tightly controlled, with further investment in Plant 2 in Georgia contingent on visible EV demand. Aspen is pursuing non-dilutive financing, including asset-backed loans and a DOE application, to maintain liquidity and avoid shareholder dilution during the ramp phase.
5. Market Leadership in Thermal Runaway Solutions
Aspen’s competitive moat is reinforced by the multidimensional performance of PyroThin, which addresses not just thermal isolation but also mechanical and assembly requirements for next-generation battery packs. The company reports no credible commercial alternatives gaining traction in customer bake-offs.
Key Considerations
This quarter’s results underscore Aspen’s transition from a capacity-constrained industrial supplier to a technology-driven EV solution provider with a disciplined financial approach and expanding addressable market.
Key Considerations:
- Backlog Monetization: Timely execution of the supplemental supply agreement is critical to unlocking $138 million in energy industrial backlog and lifting revenue ceiling.
- GM Ramp Volatility: Aspen’s 2023 outlook remains highly sensitive to the pace of GM’s EV production, with Q4 seen as a possible inflection point for both revenue and EBITDA.
- Design Win Pipeline: Near-term awards from European OEMs could accelerate revenue diversification and de-risk reliance on GM in 2024-2025.
- Cost Discipline: Sustained OPEX control and further conversion cost reductions are essential to achieving targeted margin and EBITDA levels as revenue scales.
Risks
The primary risks center on execution and timing: Delays in GM’s ramp or contract manufacturing onboarding could defer profitability and stretch working capital. The company also faces potential demand variability, competitive responses as the EV market matures, and exposure to macroeconomic or supply chain disruptions. While Aspen is not seeing effective competition for PyroThin today, this could shift as OEM requirements evolve and new entrants emerge.
