Insights

Institutional Ownership Analyst

Vanguard holds a modest, just-over-5% stake in Sun Communities (SUI).

Vanguard Capital Management reports beneficial ownership of 6,588,793 shares (5.34%) as of 03/31/2026, with sole dispositive authority over those shares and sole voting power over 1,135,719 shares.

Institutional holders at this scale commonly reflect passive or index-related positions; the filing does not state any planned transactions or changes. Subsequent filings would show any position changes.

Compliance / SEC Filings Specialist

Schedule 13G was used to report passive beneficial ownership above 5%.

The filing identifies Vanguard Capital Management and affiliated advisory divisions and follows the beneficial‑ownership disclosure rules; it declares dispositive and voting power totals and includes the standard Release No. citation. No statement in the excerpt indicates intent to influence control.

Watch for future amendments if the stake crosses thresholds or the holder changes intent, which would require different reporting.

3 terms

beneficially owned regulatory

"reflects the securities beneficially owned, or deemed to be beneficially owned, by Vanguard"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

sole dispositive power regulatory

"Sole Dispositive Power 6,588,793.00"

Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.

Schedule 13G regulatory

"Item 1. | (a) | Name of issuer: Sun Communities Inc"

A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.
