International Energy Insurance Plc recorded the steepest decline on the Nigerian Exchange (NGX) in the week ended August 28, 2026 with its share price plunging 26.61 percent as investors reacted to increased share supply following the company’s supplementary listing.
The insurance company’s stock fell from N3.87 at the beginning of the week to N2.84, shedding N1.03 per share to emerge as the Exchange’s worst-performing equity during the period.
The sharp decline came in the same week that the Nigerian Exchange listed an additional 8.075 billion ordinary shares of International Energy Insurance Plc arising from the company’s public offer of 5.469 billion ordinary shares at N3.20 per share.
Following the supplementary listing, the company’s total issued and fully paid-up shares increased significantly from 1.284 billion shares to 9.360 billion shares, substantially expanding the number of shares available for trading.
While the NGX weekly report does not attribute the decline to the supplementary listing, the selloff occurred during the same week the additional shares were admitted to trading.
International Energy Insurance’s decline stood out even as the broader market posted gains.
The NGX All-Share Index (ASI) appreciated 0.81 percent to close at 241,298.47 points, while equity market capitalisation rose 0.84 percent to N155.826 trillion.
Despite the positive performance of the benchmark index, weakness in International Energy Insurance highlighted the increasingly selective nature of investor activity across the Exchange.
The insurer also led a group of stocks that recorded double-digit weekly losses.
Fidson Healthcare Plc declined 17.69 percent after falling from N93.55 to N77.00, while Caverton Offshore Support Group Plc lost 15.15 percent.
Other notable decliners included Zichis Agro Allied Industries Plc, down 14.71 percent, Austin Laz & Company Plc, which shed 11.97 percent, Ava Capital Plc, down 10.96 percent, and Veritas Kapital Assurance Plc, which fell 10.77 percent.
The decline in International Energy Insurance contrasted sharply with the performance of several market leaders during the week.
First HoldCo Plc gained 11.58 percent to rank among the week’s best-performing stocks, while Access Holdings Plc advanced 9.26 percent, reflecting continued investor preference for selected banking stocks.
Market activity remained concentrated in financial services throughout the week.
The Financial Services Industry accounted for 1.977 billion shares valued at N71.563 billion, representing 78.87 percent of total market volume and 58.08 percent of total transaction value.
Overall, investors traded 2.507 billion shares worth N123.223 billion in 173,561 deals during the four trading sessions.
International Energy Insurance’s performance serves as a reminder that while the broader market finished the week in positive territory, stock-specific developments continued to play a significant role in shaping investor sentiment.
The sharp decline also illustrates that gains in the benchmark index can coexist with substantial losses in individual equities, particularly when significant changes in a company’s share capital occur during the trading week.
