A review of first-half 2026 financial results for four tier-two Nigerian banks—Wema Bank, Sterling Financial Holdings, FCMB Group, and Ecobank Transnational Incorporated—highlights significant improvements in operational efficiency but persistent concerns regarding asset quality and disclosure gaps.

Wema Bank emerged as the most efficient performer, successfully reducing its cost-to-income ratio from 81 percent in 2022 to 42 percent by mid-2026. While all four banks showed enhanced operational leanings, concerns remain over non-performing loans, particularly at Ecobank, where the NPL ratio rose to 7.6 percent. Notably, transparency varies significantly across the group, with banks like Wema and FCMB failing to disclose key metrics such as capital adequacy and NPL ratios in their interim filings. Despite these reporting gaps, overall profitability remains strong, with Wema and FCMB leading in earnings quality. Market valuations remain compressed, suggesting investors have yet to fully account for the observed operational turnarounds.
