[Form 4/A] STEM, INC. Amended Insider Trading Activity

Rhea-AI Filing Summary

Brian Musfeldt, Chief Financial Officer of STEM, Inc. (STEM), amended a Form 4 to report equity awards granted on 07/17/2025. The amendment discloses 2,500 RSUs that vest 100% on 08/07/2027, 6,750 PSUs that vest upon meeting a volume-weighted average price target over any consecutive 60 trading-day period, and 1,250 stock options with an exercise price of $9.27 that expire on 07/17/2035 and vest 100% on 08/07/2027. The amended filing corrects omissions and an earlier miscount: the original Form 4 omitted the RSUs and options and reported 5,500 PSUs instead of 6,750 PSUs. All reported awards are listed as direct holdings.

Insights

Corporate Governance Specialist

Amendment corrects prior disclosure errors; awards now fully reported.

The filing shows the company and its officer corrected a previously filed Form 4 to include omitted awards and to increase the reported PSU count from 5,500 to 6,750. Accurate insider reporting is important for regulatory compliance and investor transparency.

Because the amended filing documents grants made on 07/17/2025 and includes vesting schedules, it clarifies the officer's future potential ownership and resolves the earlier reporting inaccuracy.

Executive Compensation Analyst

Grants combine time-based RSUs, performance PSUs, and options with defined vesting and expiry.

The officer received 2,500 RSUs vesting on 08/07/2027, 6,750 PSUs tied to a VWAP-based 60-day stock-price target, and 1,250 options at $9.27 exercisable through 07/17/2035 with vesting on 08/07/2027. This mix uses time-based and performance-based compensation, making a portion contingent on share-price performance.

The PSU structure means vesting depends on meeting a defined 60 trading-day VWAP condition, a measurable performance trigger disclosed in the filing.
