Sun Communities, Inc
A real estate investment trust that owns and runs manufactured-housing communities, RV resorts under the Sun Outdoors brand, and holiday parks in the UK, renting out sites for homes and vacation stays. It began in 1975 as Sundance Enterprises, founded by a Michigan doctor named Milton Shiffman who had been investing in real estate on the side; his son Gary joined him, and the business was incorporated as Sun Communities in 1985. In 2025 it sold its Safe Harbor marina business to refocus on its core communities.

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: -433.2K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
