The company says it has strong grounds to contest and will file its response. The notice is preliminary, not a final order, so no material financial impact is expected currently.

Likely market impact

Preliminary tax dispute, not a final order. Potential liability up to Rs 56.7 crore if not contested, but management expects no material impact at present.
