Aspen Aerogels
ASPN
Pros
- Aspen Aerogels holds proprietary aerogel technology applied in energy infrastructure and building markets, supporting sustainability and electrification trends.
- Despite recent revenue declines, the company maintains a strong balance sheet with a current ratio near 4 and low debt-to-equity ratio around 0.34.
- Segment resilience is seen in Energy Industrial, which grew revenue 7% quarter-over-quarter, partially offsetting declines in the EV-focused Thermal Barrier segment.
Considerations
- The company projects a steep negative EPS for 2025, between -4.15 and -4.05, significantly below analyst consensus, indicating continued profitability challenges.
- Q3 2025 revenue fell 33.8% year-over-year and the stock price recently dropped sharply following an earnings miss and cautious guidance.
- Thermal Barrier revenues, largely tied to the US electric vehicle market, declined 12% quarter-over-quarter amid a reset in that sector, affecting overall performance.

Quanex
NX
Pros
- Quanex Building Products generates substantial revenue of $1.63 billion, driven by engineered components for windows and doors in residential and commercial construction.
- Recent quarter-over-quarter revenue growth surged 70%, coupled with a solid operating margin around 10%, indicating improving profitability.
- The company focuses on innovative, energy-efficient, and sustainable building product solutions aligned with green building industry trends.
Considerations
- Quanex has a relatively high P/E ratio of 52.9x reflecting expensive valuation and slim net profit margin around 1.1%, indicating limited current profitability.
- The company faces exposure to cyclicality in the construction and real estate markets, which could impact demand for building components.
- While revenue growth is strong, return on equity remains modest at 2.2%, suggesting room for improved capital efficiency.
