The register reports 15 officers in total, including past appointments, though only the 5 most relevant records are shown here.

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
Casa Systems, Inc. has no recorded parent company — it sits at the top of its own group structure, with 7 subsidiaries recorded beneath it across 6 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, France, Australia, Hong Kong, Netherlands, China 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. Two of the 7 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
