Based on reports through September 30, 2025
PTC makes the software in which products are designed and their documentation is kept from drawing to retirement.
A lifecycle management system records which version of a part sits in which product, who approved a change and what must be redone as a result. For a manufacturer with complex products it is the single source of truth, and moving that database to another system is a multi-year project.
Hence exceptionally durable relationships: a customer stays for decades, and the move to subscription made revenue almost entirely recurring. The growing part is electronics design tools and digital twins. Risks: industrial capital budgets, competition from large engineering software vendors and acquisition debt. The company pays no dividend.
