Mine to Margin: Steel Stocks' Secret Profit Play

Companies that secure their primary inputs, such as iron ore and manganese, achieve superior operating margins compared to those who purchase them on the open market. Sandur Manganese & Iron Ores Limited, India's third-largest manganese ore miner, demonstrates this by owning vast reserves in Ballari, with leases extending to 2033. Its standalone operations have consistently reported operating profit margins exceeding 40%.

Sandur's integration extends to self-sufficient coke production and captive waste-heat power, minimizing reliance on external suppliers. A significant shift occurred in November 2024 with the acquisition of Arjas Steel, nearly quadrupling revenue but reducing consolidated operating margins to approximately 24%, a figure that understates the strength of its mining operations.

Sarda Energy & Minerals Limited, another key player, differentiates itself through ownership of coal mines and an expanding fleet of power plants. Energy now constitutes about two-thirds of its operating profit. This strategic pivot has attracted notable investors like Mukul Agrawal and Abakkus Emerging Opportunities Fund.

Both Sandur and Sarda have experienced substantial stock price appreciation. Sandur's share price surged 472% from approximately Rs 36 in June 2021 to Rs 206 by June 25, 2026. Sarda Energy & Minerals Ltd saw an even more dramatic increase, from about Rs 12 in July 2021 to Rs 521 on June 25, 2026, a 4,241% jump.

Despite these successes, risks remain. The acquisition of Arjas Steel dilutes Sandur's high margins, and forest clearance issues present a compensatory demand of Rs 131 crore. Sarda faces commodity price cyclicality and execution risks in its energy expansion. Both stocks have already undergone significant re-rating, moving from undervalued to fairly valued positions.
