Insights

Institutional Ownership Analyst

Large passive holding disclosed; filer asserts non‑beneficial status.

The amendment records an institutional position of 11,632,065 shares (14.7%) as of 03/31/2026, with sole voting and dispositive powers largely aligned. This quantifies the firm's visible exposure to the company at that date.

Because the filing contains an explicit denial of beneficial ownership, the legal/constructive ownership characterization may be complex. Subsequent filings or schedules could clarify the economic interest or reporting basis.

3 terms

Schedule 13G/A regulatory

"Amendment No. 4 ) PLANET FITNESS INC - CL A COMMON STOCK"

A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.

beneficially owned regulatory

"Item 4. | Ownership (a) | Amount beneficially owned: 11632065"

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 power to dispose or to direct the disposition of: 11632065"

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.
