Mazagon Dock Surges: ₹70,000 Cr Submarine Deal

Mazagon Dock Gets Its Biggest Catalyst in Years The Union Finance Ministry has cleared the ₹70,000 crore Project-75I submarine programme to its penultimate stage before contract signing. [Mazagon Dock Shipbuilders](/stock/MAZDOCK) (NSE: MAZDOCK) will build six advanced air-independent propulsion diesel-electric submarines at its Mumbai yard in partnership with Germany's thyssenkrupp Marine Systems.

That's the kind of certainty institutional investors price at a premium. The FairStock Score for MAZDOCK currently sits in the upper band, reflecting strong earnings momentum and a near-monopoly position in Indian submarine construction. The risk, however, is execution. The P75 programme (the predecessor) ran years behind schedule. MDL knows this. thyssenkrupp knows this. The Indian ...
