Transcorp Power Plc has recorded a sharp rally on the Nigerian Exchange, gaining 23.4% across five consecutive trading sessions as market participants aggressively repriced the stock following the reaffirmation of the power generator’s 2026 earnings outlook.

The strong buying momentum pushed the company’s share price from a recent low of N178.00 to close Friday at N219.60. Across its 7.5 billion outstanding shares, the advance expanded Transcorp Power’s market capitalization by approximately N312 billion, lifting its aggregate valuation from N1.335 trillion to N1.647 trillion.

Trading interest peaked on Wednesday with a single-day 10% gain, catalyzed by an analyst briefing where executive leadership outlined concrete strategies to enhance plant availability and expand generating capacity.

The rally reflects investor focus on underlying efficiency and widening margins rather than top-line contraction. In its unaudited results for the nine-month period ended September 30, 2026, the company posted a profit before tax of N83.1 billion on revenue of N266.1 billion. While revenue declined by 14% year-on-year from N308.5 billion and pre-tax profit dropped 9% from N91.2 billion, pre-tax profit margin expanded to 31.2%, up from 29.6% in the corresponding period of 2025.

Balance-sheet strength also supported the market’s positive reception. Total assets grew 11.7% to N629.5 billion, while shareholders’ funds rose 8.9% to N199.8 billion. During the third-quarter conference, management indicated that the balance sheet benefited significantly from accelerated cash collections, orderly debt settlements, and a net reversal of credit loss provisions.

Commenting, Transcorp Power Chief Executive Officer, Peter Ikenga explained that performance had been dampened by external operational headwinds outside the firm’s direct control, notably persistent transmission bottlenecks, grid infrastructure vandalism, and periodic gas supply curtailments.

Industry analysts concurred with the assessment, noting that broader power-sector valuations continue to navigate systemic structural obstacles, including gas feed reliability, national grid wheeling capacity, infrastructure security, and the liquidity discipline of power-purchase counterparties.
