Cabot Corporation
A global specialty chemicals maker headquartered in Boston, Cabot produces carbon black — the fine black powder that strengthens tires and industrial rubber goods — along with fumed metal oxides, battery materials, and inkjet colorants for industries from automotive to electronics. Founded in 1882 by Harvard-trained chemist Godfrey Lowell Cabot, the company was built around a process he patented for turning natural gas by-product into valuable carbon black. Today its EVOLVE® platform also makes sustainable carbons recycled from end-of-life tires, turning old rubber into new raw material.

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: -586.7K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
