If multiple subsidiary brands within a larger company seek to achieve certification, the combined revenue of all certified entities will be used to determine certification requirements for each brand. For example, suppose a parent company has Brand A with $80m in annual revenue and Brand B with $25m in annual revenue. Both Brand A and Brand B would be subject to the requirements for companies >$100m in revenue, regardless of the decision to pursue one certification at the parent level or separate certifications for each brand (see this link)
