Louisiana-Pacific Corporation
A maker of engineered wood building products, Louisiana-Pacific is the largest producer of siding in North America, with brands like LP SmartSide used by home builders and renovators. Born in 1973 when a court-ordered antitrust ruling forced Georgia-Pacific to spin off part of its business, it kept the "Pacific" and added Louisiana. In 1979 it opened North America's first oriented strand board mill, a product so popular the plant ran around the clock.

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 all recorded history: -529.4K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
