Sources:13G by Polar Asset Management Partners (May 15, 2026) ↗All of the company's proxy statements on EDGAR ↗
13F percentages divide the shares each institution reports by the Class A shares outstanding on the cover of the company's latest report before the quarter end (May 15, 2026). Entities of the same group file separately and are not added up. With more than one share class, a 13D or 13G counts shares convertible from another class as owned, so we do not show its percentage. We hold 13D and 13G filings made since Dec 23, 2024: a holder above 5% that has not filed since then does not appear here.

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.
Fundamentals
Balance sheet only, for now. IACO has not yet filed its first annual report (10-K) with the SEC, so there are no 12-month figures (revenue, margins, earnings and cash flow). We show the balance sheet from its latest filing; once the 12-month figures are available, this section fills in automatically.
- Cash and equivalents
- $1.2M
- Total debt
- $251K
- Net cash
- $917K
- Shareholders' equity
- $-13.1M
Balance sheet figures the company filed with the SEC (10-Q or 10-K), in dollars. Net debt = total debt − cash − investments; when negative, the company has more cash than debt (net cash). How each figure is calculated
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.

Above 5% (13D/13G)
Disclosed stakes, with their amendments. A filing is not always a purchase: there are also reductions and changes of filing entity.
This list may be incomplete: we hold 13D and 13G filings made since Dec 23, 2024. A holder above 5% that has not filed anything since then is not shown here.

Flagged material events (8-K)
Unregistered sale of equity securities (Item 3.02)
Change in directors or officers (Item 5.02)
Alert items the company itself flagged in its 8-K filings with the SEC, most serious first. It is the form's label, with no interpretation from us: Item 5.02 covers routine appointments as well as a chief executive's departure; open the filing. The quoted headline is the original press release's.
