Is Mangalore Refinery and Petrochemicals Limited undervalued?
We estimate the fair value of Mangalore Refinery and Petrochemicals Limited at ₹232 per share, against a market price of ₹176. That puts the share price about +31.9% below our estimate, at low confidence. This is our view of what the business is worth, not a target price or a forecast of where the share price will go.
How this fair value is calculated
This estimate comes from 2 methods: Discounted cash flow (2-stage) (₹356), Fair multiple (P/E) (₹108). These methods disagree materially, so the estimate is their midpoint rather than a weighted blend, and the disagreement is part of the finding. The full working, including the assumptions and what data was missing, is set out below.
The range around this estimate
Our estimate for Mangalore Refinery and Petrochemicals Limited spans ₹108 to ₹356. That range is wide, which is the honest signal here: read the range rather than the single number. A margin of safety means buying meaningfully below the estimate: the wider the range, the more room the assumptions leave for error.

Estimate range ₹108 – ₹356
Why this method for this business
MRPL is a capital-intensive energy business with cyclical earnings and high debt. DCF is appropriate for its cash flow generation, while relative PE captures sector multiples and market sentiment.
The models behind the number
These methods disagree materially, so the estimate is their plain midpoint rather than a weighted blend. The disagreement is itself the finding.
Intrinsic value from 2-stage discounted cash flows (primary for asset-light / normal businesses); FCFF path
- ev_ebitda is not used due to lack of reliable EBITDA multiples for the energy sector
- forward-looking DCF is not used due to the cyclical nature of the business and the need for normalized earnings
What was missing
- Lack of forward-looking EBITDA multiples for the energy sector
- Limited analyst coverage and dispersion in earnings estimates

Who computed this
A language model (qwen3:8b) selects the valuation method and the judgement inputs for Mangalore Refinery and Petrochemicals Limited: which models suit the business, the moat, the growth and margin assumptions. It does not produce the number. The fair value itself is computed in Python by a deterministic engine (version 2026.08.1) from those inputs, so the same inputs always give the same result and every figure above can be traced to a source.

How we value stocks
We estimate what a business is worth from its own economics: cash flows, returns on capital, and a multiple justified by its quality, rather than from where the share price has been. A fair value estimate is a view, not a verdict, and it is only as good as the inputs listed above.
