Insights

Institutional Ownership Analyst

Ariel holds a sizable 15.2% stake in OneSpaWorld as of 03/31/2026.

The filing reports 15,432,414 shares beneficially owned and 13,537,401 shares with sole voting power. This signals a substantial passive stake under Schedule 13G/A disclosure norms rather than an activist Schedule 13D filing.

Voting and dispositive power are disclosed explicitly; subsequent filings could show changes. Timing: the beneficial ownership figure is anchored to 03/31/2026 and the amendment was signed 05/14/2026.

Compliance & Corporate Governance Specialist

Adviser-client allocation and economic-interest disclosure are clarified.

The statement notes adviser clients have rights to dividends/proceeds, while none of those clients holds >5% economic interest. This clarifies that Ariel reports aggregated voting/dispositive authority for managed accounts rather than a single dominant client.

Practical implication: the filing documents control metrics (voting/dispositive power) without asserting a change in strategy or plans.

Key Terms

Schedule 13G/A, Beneficially owned, Sole dispositive power

3 terms

Schedule 13G/A regulatory

"Amendment No. 11 ) OneSpaWorld Holdings Ltd ..."

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 financial

"Item 4. | Ownership (a) | Amount beneficially owned: 15,432,414"

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

"(iii) Sole power to dispose or to direct the disposition of: 15,432,414"

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.
