Nesco - a potential 2 or 3 bagger

I've been following nesco for sometime. The balance sheet looks so solid, great fundamentals, no red flag at all. Its almost at its ATH, but still seems undervalued when compared to the PAT growth. Also they recently got 2 tenders from NHAI with a revenue potential of 700 cr annually after 3 or 4 years (Their current annual revenue is 700 cr). Overall looks like a solid bet having atleast 2 or 3 bagger potential in next 4 years. Is there anyone else following this stock or any red flags im missing?
