The market expects Sona BLW to do better than it ever has.
At today’s share price, buyers are assuming Sona BLW grows about 35% a year, forever. Over the last ten years it actually grew about 21% a year. So the share price only makes sense if the business improves on its own track record. If it simply carries on as before, buyers today have paid for something they will not get.
- How it is valued: Discounted cash flow.
- What the price assumes: 35% growth, against 21% the model takes from its own record.
- Ten-year record: Between FY2022 and FY2026, Sona BLW's revenue went from ₹2,131 crore to ₹4,475 crore — it compounded at about 20% a year over 4 years.
- Biggest swing factor: EV adoption. Main risk: EV slowdown.
