CGN Power (SEHK:1816) Could Be 25% Undervalued As First Half Output Softens

CGN Power (SEHK:1816) drew fresh investor focus after reporting first half 2026 operating data, with total nuclear power generation and on grid output both below the levels reported a year earlier.

CGN Power's recent operating update came as the share price closed at HK$2.88, with a 7 day share price return of 5.49% and a 90 day share price return that declined 15.04%. The 5 year total shareholder return of 110.13% points to a much stronger long run outcome.

After softer first half output and a recent bounce in CGN Power's share price, the discussion now turns to what you are actually paying for the stock and whether the current valuation still tilts the risk reward towards buyers.

Price to earnings of 13.2x for CGN Power: Is it justified?

On the latest data, CGN Power trades on a P/E of 13.2x, which our checks flag as mixed value territory compared with both its peer group and an internal fair value benchmark.

The P/E multiple compares the HK$2.88 share price with the earnings generated per share, so it captures what investors are currently paying for each unit of profit. For a regulated, capital intensive utility such as CGN Power, this lens is a common shorthand for how the market is weighing steady cash generation against growth expectations.

Two signals pull in different directions. On one hand, the stock is described as good value versus the wider Asian renewable energy industry average P/E of 15.6x, which suggests the broader sector trades on a richer earnings multiple. On the other hand, CGN Power is described as expensive versus a closer peer average P/E of 7.7x, and also above an estimated fair P/E of 12.1x that the SWS framework indicates the multiple could converge toward over time.

Putting those pieces together, the current 13.2x looks modest compared with the regional sector but richer than both near peers and the modelled fair ratio level.

Result: Price to earnings of 13.2x (OVERVALUED)

However, there are clear risks for CGN Power if softer first half output persists, or if sector peers continue to trade on materially lower P/E multiples.

Another view on CGN Power's value

While the P/E discussion paints CGN Power as slightly expensive at 13.2x versus a 12.1x fair ratio, the SWS DCF model points the other way, with an estimated fair value of HK$3.60 versus the HK$2.88 share price. This suggests the stock is undervalued based on cash flow assumptions.

This split between earnings-based and cash flow-based signals leaves a practical question for you as an investor: which lens do you trust more when short term output data looks soft but long term nuclear assets are still generating cash?

Look into how the SWS DCF model arrives at its fair value.
