Leadership

SI estimate

5.4/10

What are the people in charge doing?

SI estimate 5.4/10, confidence 20 of 100 (family median).

weight 22% of this tense · 50th percentile among 78 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 78 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 2026-03-18 (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.
How it was reasoned: family median, 78 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: United Microelectronic Corp.'s leadership is put at 5.4 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 78 members with one. Its next annual report on file with the inputs replaces this estimate with the filed reading.

top 44% of 93 in its family for growth drivers.

weight 45% of this tense · 56th percentile among 93 sector filers · read for its customers

From the record

United Microelectronic Corp.'s growth drivers, from the filed years to fiscal 2024: revenue grew 2.9% a year over the last three filed years against 5.4% over all 10, slowing (top 37% of its family); the newest year grew 4.4% (bottom 36%); research spending grew 6.5% a year (top 48%); capital spending grew 22.6% a year (top 26%) (its annual reports).
