Why Did ASPN Stock Plummet 25% Today?

• Aspen posted a net loss of $72.9 million, or $0.88 per share, compared with net income of $11.4 million last year.

• Aspen forecast revenue of $35 million to $40 million and net loss of $20 million to $23 million for Q1 FY26. 

Shares of Aspen Aerogels (ASPN) slumped 25% on Wednesday, after the company reported a sharp decline in fourth-quarter results and launched a strategic review to strengthen its long-term positioning.

ASPN shares were trading at their lowest levels since April 2019.

Fourth-quarter (Q4) revenue crashed 66% to $41.3 million, pressured by weaker demand across Thermal Barriers and Energy Industrials business segments. Analysts, on average, had expected a revenue of $44.3 million, according to Fiscal.ai data.

Aspen posted a net loss of $72.9 million, or $0.88 per share, compared with net income of $11.4 million last year. The company said that its bottom line was impacted by restructuring, asset impairment, and other one-time charges. Excluding these items, adjusted net loss was $27.7 million, or $0.34 per share.

Strategic Review To Enhance Long-Term Prospects

Aspen also launched a strategic review to strengthen its long-term positioning, it said. As part of the process, the company will evaluate a wide range of strategic alternatives to ensure it is properly structured. To support the review, Aspen appointed Piper Sandler & Co. as its exclusive financial advisor.

“Our focus is clear — to ensure the company’s strategy, capital allocation, and asset base are aligned to maximize value creation,” said Don Young, President and CEO.

For the first quarter of 2026, the company forecast revenue of $35 million to $40 million and a net loss of $20 million to $23 million. 

The company confirmed that its Q4 2025 EV customer award is for Volvo Cars. In the previous quarter, Aspen was also awarded a North Sea subsea pipeline project, with delivery expected in Q3 2026.
