Hyzon Motors

How it happened

Hyzon Motors was a US developer of hydrogen fuel-cell systems for heavy trucks, valued around $2.7B after a 2021 SPAC merger. Accounting scrutiny, delayed commercialization, and mounting losses pushed its stock well below $1B, and it moved to wind down operations in 2025 — down roughly 95% from peak. Glassdoor reviews describe a management-heavy organization: many said bosses outnumbered the working engineers, and flagged a clique that installed friends retired from legacy automakers over technical staff. Insiders also questioned whether the fuel-cell trucks had a real market, citing low-quality China-sourced parts, and employees were openly predicting the company's demise more than a year before the wind-down.
