Oil India’s Valuation Premium Over ONGC: Market Flows and Fundamentals Diverge

Oil India is trading at a sizeable valuation premium to ONGC even as the two state-owned energy producers operate under similar fiscal conditions and remain exposed to many of the same movements in crude oil and natural gas prices. 

A September 21 report by Kotak Institutional Equities put the difference into numbers. Oil India’s domestic operations were valued at 7.7 times one-year forward earnings, compared with 3.4 times for ONGC’s standalone business. 

The gap is also visible on an enterprise value-to-EBITDA basis. Oil India was valued at 6 times, while ONGC stood at 2.7 times. 

Their recent share-price performance has moved in different directions as well. Oil India gained 14% over the preceding three months, while ONGC declined 4% during the same period. 

Oil India trades at more than twice ONGC’s P/E multiple 

The difference between the two companies is particularly pronounced on forward earnings. 

At 7.7 times one-year forward P/E, Oil India’s domestic business commands more than twice the multiple assigned to ONGC’s standalone operations at 3.4 times. 

Kotak’s comparison found a similar pattern using EV-to-EBITDA. Oil India’s multiple of 6 times compares with 2.7 times for ONGC. 

The brokerage described Oil India’s valuation premium as difficult to justify, particularly given the similarities in the operating environment for the two companies. 

Both are exposed to changes in global crude oil and gas prices and operate under broadly similar fiscal regimes. 

Share-price performance moves in opposite directions 

The valuation difference has widened alongside contrasting stock-market performance. 

Over three months, Oil India share price advanced 14%, while ONGC share price fell 4%. 

Kotak linked part of this divergence to the market’s preference for mid-cap companies over their large-cap counterparts rather than to a comparable difference in operating fundamentals. 

Fund flows provide some context to that trend. Mid-cap and small-cap mutual funds together accounted for 32% of equity-oriented fund flows during the eight months through August 2026. 

Their share increased to 42% during the June-August period. 

The weighted-average net asset value of mid-cap funds had also moved above its September 2024 peak by May 2026. 

ONGC leads on capital returns and cash conversion 

The comparison changes when the two companies are viewed through capital efficiency and cash-generation measures. 

ONGC’s standalone return on average capital employed stood at 11.2% in FY26. Oil India’s corresponding figure was 6.1%. 

Free cash flow relative to profit after tax also favoured ONGC. The ratio stood at 105% for ONGC compared with 78% for Oil India. 

These numbers sit alongside a market valuation that currently assigns substantially higher earnings and EBITDA multiples to Oil India. 

Kotak’s assessment therefore centres on the difference between the relative financial metrics of the two companies and the multiples at which their businesses are being valued. 

Mid-cap flows remain part of the valuation debate 

The brokerage’s analysis points to market flows as one factor behind Oil India’s recent outperformance. 

The rising share of equity flows directed towards mid- and small-cap funds has coincided with Oil India gaining ground in the market, while ONGC has moved lower over the same three-month period. 

Kotak questioned the market assumptions embedded in this valuation difference, describing Oil India’s premium over ONGC as difficult to justify. 

The comparison does not establish that fund flows alone account for the valuation gap. It does, however, show a clear divergence: Oil India has recorded stronger recent share-price performance and trades at substantially higher valuation multiples, while ONGC reported higher FY26 return on capital and stronger free-cash-flow conversion.
