nostr:npub14yqjkzqkgv4a27egvq5xmh2ravemytg9g5kldqeqfts92uvh90sq2vrfl3 My gut reaction would be three holding companies owning a production company.

Stores only interface with the production company - keeping a simple familiar interface there.

When profit is produced in the production company, it is paid to the holding companies as dividends.

The actual people work out taxes in their home country and only have to deal with their relationship with their own local holding company.
