Insolation Energy SME IPO

Management guided for 1300 Cr. PAT for FY2028. If market gives 10 PE Mcap will be 13,000 Cr. If it gets 15 PE then 19,500 Cr. Mcap. by FY28. Current Mcap is only 2940 Cr. Current PE 16.6

Is my understanding correct?

Disc. invested

The P/E has fallen a lot due to rise in earnings and fall in price. Is it attractive at the current P/E of ~17?
