Leadership

SI estimate
4.6/10

What are the people in charge doing?

SI estimate 4.6/10, confidence 20 of 100 (family median).

weight 22% of this tense · 50th percentile among 17 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 2026-03-17 (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 7 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 17 members with one.
What the record cannot read
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 2026-03-17 (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 7 months and cannot see past it; a floor under five years is not read as years in charge.
How it was reasoned
family median, 17 readings behind it.
Confidence
20 of 100
What would change it
Its next annual report on file with the inputs replaces this estimate with the filed reading.

From the record

SI estimate, not a filed reading: Tantech Holdings Ltd.'s leadership is put at 4.6 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 2026-03-17 (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 7 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 17 members with one. Its next annual report on file with the inputs replaces this estimate with the filed reading.
