Two ways you can do this:

1. ExListPersons can access EXShowCompany through its 'parent' instance
variable.  So ExListPersons can simply check 'parent companyID'.

2. ExShowCompany can use #addHandlers to pass information down to
ExListPersons.  For example,

ExShowCompany>>addHandlers
  (template elementNamed: 'persons')
    onDisplay: [:p | p companyID: companyID]

Does this work for what you need?
