Why this edge matters
ROHM (major in IDM) is a tracked supplier of STMicroelectronics (major in IDM). Japanese power and analog IDM; early mover in SiC devices. European IDM spanning MCUs, sensors, analog and SiC power. The edge is one of 5 tracked suppliers of STMicroelectronics and one of 3 tracked customers of ROHM.
Source: derived from both company records and the counted edges.
Concentration / risk note
ROHM has only 3 tracked customers in this dataset. Demand-side concentration is high.
Basis: few customers. Omitted on edges where the graph does not back a concentration claim.
