Seplat Energy: An Example of Resilience
While the overall index is high, individual stock performance varies. Seplat Energy Plc, the only oil and gas company on the Premium Index, currently ranks eighth among the top performers with a year-to-date gain of 3.81 per cent.
- Despite a slow start to the year, Seplat has shown resilience, recovering from a May low to post a strong gain in October.
- The company’s performance is underpinned by solid financials, with its first-half 2025 pre-tax profit surging 86 per cent year-on-year to N454.1 billion.
The Premium Index’s performance highlights the strong gains made by Nigeria’s highest-quality, largest-capitalisation stocks this year.
