Who owns Otsuka Holdings?
Otsuka Holdings trades in the U.S. through ADRs, certificates that represent shares of a non-U.S. company. Form 13F counts ADRs while the company reports ordinary shares, so we do not compute percentages. As of Jun 30, 2026, the largest ADR holders reported on Form 13F were Aristotle Capital Management (2.9 million ADRs), Boston Common Asset Management (82,860 ADRs) and Hantz Financial Services (70,560 ADRs).

The 10 13F filers with the most shares as of Jun 30, 2026, whatever their type (index firms usually come first). “Change”: shares added or cut versus the previous quarter, split-adjusted; “no data” = there is no comparable portfolio for the previous quarter (no filing, or a filing with its holdings under confidential treatment). “% of the company” only where shares outstanding are up to date. Entities of the same group file separately and some 13F filings include other managers: there may be double counting. With a free account: the top 25, the largest buyers and the largest sellers.
Insiders (Form 4)
Open-market purchases, excluding 10b5-1 plans. Officers and directors only; joint filers of the same purchase count as one. 10% owners with no role are shown separately. 0 = nobody bought; “no data” = we do not have its Form 4 filings.

This company filed no 8-K forms in the last year. Foreign companies listed in the US (ADRs) report material events on forms 6-K and 20-F, and ETFs and funds do not file 8-Ks. If it is a foreign company listed in the US through ADRs (American Depositary Receipts), what trades are bank-issued certificates that represent shares from its home market. See its filings on EDGAR ↗
