FAQ
Which listed companies are LEO satellite stocks plays?
Based on each company's own annual report disclosures, this map currently places 7 Taiwan-listed companies: MTI（2314）、VPEC（2455）、WIN（3105）、TrueLight（3234）、UMT（3491）、RPTK（6980）、TMYTEK（7812）. A company's position is determined by the products its annual report says it makes — with the original excerpt cited.
Which Taiwan companies are SpaceX suppliers?
Annual reports almost never name specific customers, so this site does not assert any supply relationship with SpaceX or any other operator. What the market calls "SpaceX supplier stocks" overlaps heavily with the LEO satellite chain shown here — antenna, ground-equipment and RF component makers. The map shows what each company discloses it makes, with sources; the rest is convention, not fact.
Where does the data on this map come from?
Two sources, styled differently on the map: relations tagged with a stock code are extracted from that company's annual report (click an edge to see the original Chinese excerpt and page); the backbone chain is an editorial framework that keeps the chain connected end-to-end. Company placements come 100% from disclosures — nothing is inferred.
Why do some items show no companies?
Dashed items have no collected annual-report disclosure yet — the segment may be dominated by non-Taiwan or unlisted players, or simply not yet covered. We deliberately distinguish "no companies" from "not yet covered".
