Owens Corning
A maker of asphalt shingles, fiberglass and foam insulation, and doors sold through distributors and home centers across North America, Europe, and Latin America. Founded in 1938 as a joint venture of glassmakers Owens-Illinois and Corning Glass Works, it takes its name from the two. Its pink insulation, tinted since the 1950s, made it the first US company to trademark a single color—PINK®—in 1987, and the Pink Panther has been its mascot since 1980.

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: -209.0K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
