Mativ Holdings, Inc.
A maker of engineered specialty materials used in everyday essentials, Mativ produces filtration media that cleans air and water, plus tapes, labels, packaging, and healthcare products sold in over a hundred countries. It was born in 2022 when two storied manufacturers — Schweitzer-Mauduit (spun off from Kimberly-Clark in 1995) and Neenah — merged, and the name "Mativ" was coined to nod to material science. Among its innovations is Gessner filter media that swaps fossil-based resins for lignin, a natural polymer from wood.

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: +378.9K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
