Our engagement did not include an assessment of the adequacy or effectiveness of TRUE’s overall sustainability strategy, nor did it
evaluate the management of sustainability‑related issues beyond the scope of the specified KPIs and Sustainability Performance Targets

2025 reporting period. During the assurance process, TUVN did not come across the limitations to the scope of the agreed assurance
engagement. No external stakeholders were interviewed as a part of the sustainability engagement for the reporting period.
