Ecovyst Inc.
A specialty chemicals company that regenerates sulfuric acid for oil refineries and makes catalysts and silica-based materials used in refining, emissions control, and cleaner fuels. Its roots stretch back to 1831, when a Quaker named Joseph Elkinton opened a soap-and-candle shop in Philadelphia that later became PQ Corporation, maker of sodium silicate "waterglass." The company renamed itself Ecovyst in 2021 after selling its performance-chemicals business to focus on sustainability-minded products.

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: -122.01M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
