While such regulations aim to drive transformative change, responses often remain compliance-driven and symbolic. Drawing on interviews with OEMs and a sustainability expert, the study finds that identity dynamics shape whether regulation prompts deep, coherent change. It introduces the Strategic Identity Alignment Framework (SIAF), which links regulatory disruption to identity and strategy alignment. The findings offer insights for scholars of sustainability transitions and top managers in legacy industries navigating identity-rooted tensions in strategic transformations.engOrganizational identitySustainability transformationStrategic adaptationIdentity change regulatory disruptionAutomotive sectormaster thesis203990951
