Nextpower Inc.
A maker of solar tracker systems that tilt panels to follow the sun, Nextpower (formerly Nextracker) supplies hardware and software like the NX Horizon tracker and TrueCapture AI to utility-scale solar plants and their builders. Born in 2013 when Solaria spun off its tracker tech, it rebranded in 2025 to reflect growth beyond tracking. Its earliest tracker was nicknamed the "Self-Powered Tracker" because each row ran on its own motor and battery, skipping the trenching other systems needed.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: -11.68M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
