Greenidge Generation Holdings Inc.
A power-generation and digital-infrastructure company that runs a natural-gas plant on the shores of Seneca Lake in Dresden, New York. That same plant, originally built as a coal-fired station in 1937, has powered the company's own bitcoin-mining operations alongside feeding electricity to the local grid. The company went public in 2021 through a merger with Support.com, and recently rebranded from Greenidge to Vulcan Infrastructure and Power as it shifts toward powering AI and high-performance computing sites.
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: +147.6K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
