Insider transactions

EDGAR

HORIZON SPACE ACQUISITION I CORP.

Transactions reported by directors, officers and 10% owners on SEC Forms 3, 4 and 5, read from each filing’s XML. Codes and their wording are the SEC’s own.

A Form 4 is due within two business days of the transaction, so the most recent trades may not be filed yet.

Window: transactions dated on or after 2025-11-15.

Open-market purchases (code P)
0 transactions, — shares
Open-market sales (code S)
0 transactions, — shares

Totals add the filed transactions listed; they are counts of what was reported, not a measure of direction.

This issuer has insider filings in the store, but no transaction in this window or code group.

Institutional holders (Form 13F)

No Form 13F position in this issuer is placed in the store. A holder not yet linked or not yet filed is absent, not zero.
