Executive Summary

Steel Partners Holdings L.P. filed an amended Schedule 13D confirming its 17.8% stake in Spruce Power (3,429,380 shares) remains unchanged. The key update is that Benjamin Rosenzweig, a Steel Partners executive, joined the Spruce Power board on September 18, 2026, following the resignation of director Clara Nagy McBane. This board appointment signals Steel Partners' deepening influence and likely escalation of its activist campaign, especially given the recent proxy solicitation challenges at the August 2026 annual meeting.
