Four healthcare companies listed on the Nigerian Exchange have delivered impressive gains so far in 2025.

Notably, all four are pharmaceutical companies whose strong financial performance appears to have boosted investor confidence throughout the year.

Collectively, these firms reported a cumulative pre-tax profit of N23.5 billion in the nine months ended September 2025, a solid 125.20% increase from N10.4 billion in the same period of 2024.

This surge was driven by stronger sales of pharmaceutical products and other healthcare-related services, with combined revenue rising to N187.6 billion, up from N114.8 billion a year earlier.

Beyond earnings, their balance sheets have also demonstrated resilience, with total assets and equity positions expanding across all four companies.

With that context, here are the four pharmaceutical companies that have delivered the biggest returns for investors so far in 2025.
