The business model is exclusively B2B and OEM-embedded. Revenue is generated through direct enterprise sales to automotive manufacturers, data-center and cloud operators, medical device OEMs, and industrial vehicle producers, with pricing negotiated per project or volume contract (no public pricing). The company co-develops custom products to customer specifications under black-box design agreements and supports products through full lifecycle from concept to series production. Approximately 600+ engineers across the German and UK sites are supported by Delta Group's global infrastructure of 73 R&D centers, 55 manufacturing sites in Europe and Asia, and 165 sales offices, enabling dual-region manufacturing and direct enterprise account management. Certification coverage (IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, TISAX, IEC 60601) and ASPICE-compliant software development create barriers typical of safety-critical automotive and medical applications.
