Leadership

SI estimate
5.8/10

What are the people in charge doing?

SI estimate 5.8/10, confidence 20 of 100 (family median).

weight 22% of this tense · 50th percentile among 8 sector filers · read for its shareholders

SI estimate Inferred, not read as filed

Why it is an estimate
It files no Form 8-K (a foreign issuer reports on Form 6-K), so officer and director changes cannot be read there; the record of its people begins on 2026-03-18 (a listing, a merger or a first filing under the rules) and its chief executive and most of the people in charge have filed since then, so the record shows a floor of 8 months and cannot see past it; a floor under five years is not read as years in charge, so the desk assumes the typical reading of its industry family, the median of 8 members with one.

How it was reasoned

What would change it

From the record

SI estimate, not a filed reading: C3is Inc.'s leadership is put at 5.8 of 10 with a confidence of 20 of 100, because it files no Form 8-K (a foreign issuer reports on Form 6-K), so officer and director changes cannot be read there; the record of its people begins on 2026-03-18 (a listing, a merger or a first filing under the rules) and its chief executive and most of the people in charge have filed since then, so the record shows a floor of 8 months and cannot see past it; a floor under five years is not read as years in charge, so the desk assumes the typical reading of its industry family, the median of 8 members with one.
