Seplat Energy Plc has become the first company listed on the Nigerian Exchange Limited (NGX) to see its share price cross N10,000.

Stock market data from Tuesday showed the company’s shares closed at N10,450, up from N9,550 recorded a day earlier. The 9.42 percent increase pushed Seplat into a new price range never before reached by any stock on the exchange.

Since the beginning of the year, Seplat’s share price has climbed sharply from N5,610 on January 2 to N10,450. This represents a gain of N4,840 per share, or 86.27 percent year-to-date.

The rise has added significant value for investors. Shareholders have recorded a combined gain of about N2.90 trillion within the period, while the company’s market capitalisation increased from N3.36 trillion to N6.26 trillion.

Analysts link the steady rise in the company’s stock to increased investor confidence after a major stake purchase in late 2025. In December, businessman Tony Elumelu, through Heirs Energies, acquired a 20 percent stake in Seplat in a $500 million deal. Since then, the company’s share price has risen by more than N4,600.

With this milestone, Seplat is now ranked among the most valuable companies on the NGX, behind Airtel Africa, BUA Cement, Dangote Cement, BUA Foods and MTN Nigeria.
