Talen Energy Corporation
A U.S. independent power producer that runs roughly 13 gigawatts of power plants, anchored by the Susquehanna nuclear plant in Pennsylvania and a fleet of natural gas and coal facilities serving the mid-Atlantic grid. It sells electricity through long-term contracts, including a deal to supply carbon-free nuclear power to Amazon Web Services through 2042, and keeps two Maryland coal plants running under reliability-must-run agreements. The company is expanding its gas-fired baseload generation through acquisitions such as Freedom, Guernsey, and the pending Cornerstone deal.

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 5 years: -5.28M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
