The instrument in this event
Read from the adjusted series, so a capital increase or a cash dividend in between does not show as a drop.
Shareholder register
The Tehran exchange register, as of Oct 4, 2026. The named holders together hold 46.90% of the shares.
Source: the Tehran exchange's daily shareholder register. The exchange names only holders at roughly one percent and above, so this is a floor on known ownership: the rest is spread across smaller holders it does not name.
