Group Structure
ALLEGRO MICROSYSTEMS INC. sits 1 level below its ultimate parent, SANKEN ELECTRIC CO., LTD., registered in Japan. 6 subsidiaries are recorded beneath it, across 2 jurisdictions. The full chain up to SANKEN ELECTRIC CO., LTD. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by ALLEGRO MICROSYSTEMS INC.'s own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 6 subsidiaries span United States, Philippines jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. One of the 6 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
