How it happened

Stem Inc sells AI-driven software (Athena) and services to optimize battery-storage and solar assets, and went public in April 2021 via a SPAC merger with Star Peak Energy Transition Corp amid clean-energy enthusiasm. Growth disappointed, bookings and revenue fell, and losses persisted; the stock dropped about 97% from its post-merger highs, traded below $1 and drew an NYSE delisting warning. Its CEO stepped down in 2024 as the company launched a strategic review. Through the slide, Glassdoor reviews described constant strategy pivots and leadership turnover, recurring layoff rounds that staff complained repeatedly landed before stock grants vested, and an unresolved hardware-versus-software identity question as talent left.
