Management authority at IMPINJ, INC. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
IMPINJ, INC. has no recorded parent company — it sits at the top of its own group structure, with 7 subsidiaries recorded beneath it across 7 jurisdictions. 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 7 subsidiaries span United States, Brazil, Finland, Taiwan, United Kingdom, Thailand, and 1 more 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 7 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
