Bloom Energy Corporation
A maker of solid-oxide fuel cells, Bloom Energy builds the Bloom Energy Server — boxy units that quietly turn natural gas, biogas, or hydrogen into electricity without burning anything, powering data centers, factories, and utilities. Its roots trace to founder K.R. Sridhar's NASA work on making oxygen for Mars; when that mission was shelved, he flipped the idea to make power on Earth. The fuel-cell stacks are built from cheap sand-like materials, and the company's name hints at the idea of clean energy "blooming" wherever it lands.

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: -11.58M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
